Physicists show that superfluid light is possible

first_img Citation: Physicists show that superfluid light is possible (2010, October 27) retrieved 18 August 2019 from ( — Superfluidity – the phase of matter that enables a fluid to move up the sides of its container – has been known about since the 1930s. Since then, superfluidity has become a prime example of how quantum effects can become visible on the macroscopic scale under certain conditions. Although physicists have previously considered the possibility of superfluid light, their results have been inconclusive until now. In a new study, physicists from France have theoretically shown that superfluid motion of light is indeed possible, and have proposed an experiment to observe the phenomena.

This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of Explore further In their study published in a recent issue of Physical Review Letters, Patricio Leboeuf and Simon Moulieras from the University Paris-Sud and CNRS explain that superfluidity is the ability of a fluid to move with zero dissipation or viscosity. A fluid behaves like a superfluid only under a certain critical velocity; above this critical velocity, superfluidity disappears. Most commonly demonstrated in liquid helium, superfluidity occurs when the helium is cooled and some helium atoms have reached their lowest possible energy. At this point, these atoms’ quantum wave functions begin to overlap so that they form a Bose-Einstein condensate, in which all the atoms behave as one large atom, and their quantum nature is manifested on the macroscopic scale.Previously, investigations of the superfluid motion of light have not revealed clear evidence of the existence of a superfluid critical velocity. Although some recent experiments have observed superfluidity related to light, these experiments did not use photons, but a composite particle, called a polariton, which is a mixture of a photon and an exciton. In this study, Leboeuf and Moulieras have shown that a superfluid critical velocity does exist in a nonlinear medium. They explain how superfluid light can be observed in an array of waveguides. From a dynamical point of view, light propagating through a nonlinear medium is formally equivalent to a Bose gas of interacting massive particles. Light can travel straight along the waveguides in the longitudinal direction, or it can tunnel between adjacent guides in the transverse direction. The benefit of this set-up is that it allows the scientists to engineer different characteristics of the array and control the light’s flow.The physicists were specifically interested in what happens to a light pulse as it travels through the array at different velocities in the presence of a defect. If the light is scattered by the defect, it means dissipative processes have occurred. If the light pulse moves through the defect without changing its shape (i.e., without losing collectivity), there is no dissipation and the light has superfluid motion. Through their calculations, the physicists showed that, for certain low velocities, the transverse motion of light is superfluid with zero dissipation. When the velocity increases, dissipative processes occur that destroy the collectivity of the light’s oscillations, and superfluidity breaks down. In the future, the physicists plan to further investigate additional details of superfluid light, such as how it relates to an underlying quantum theory of light and how it is connected to Bose-Einstein condensation. They predict that superfluid motion is a general property of light that exists in a variety of scenarios, and is not limited to the waveguide array proposed here. Superfluid light could also have applications in light transport optimization.“One straightforward implication is related to transport in the presence of noise,” Leboeuf said. “Such a noise is expected to be present generically, since any material has imperfections and impurities. The impurities are responsible for the scattering of light. In the superfluid regime, we expect a light pulse to be able to propagate through a noisy medium without being affected or scattered (perfect transmission).” Leboeuf and Moulieras plan to perform their proposed experiment and are discussing the opportunity with experimental groups at the Laboratoire de Photonique et de Nanostructures (LPN) at Marcoussis, France. However, the scientists said that superfluid light is not likely to have any strange effect analogous to a superfluid flowing up a container.“The most basic ‘strange’ quantum effect that light shows related to superfluidity is, as shown in our article, dissipationless motion,” Moulieras said. “Another, though more indirect or spectacular, effect is related to quantized vortices, which were observed in laser patterns propagating through nonlinear media. Concerning other possibilities, such as fluid motion up the walls of a container, they are related, for atoms, to the forces between these atoms and a substrate, and the balance between capillary, gravity and viscous forces. We do not see a straightforward application of these concepts to photons, and therefore do not expect them for light.”last_img read more

Another model has enhanced wireless conductivity, which allows for easy streaming of web-based presentations and video streams. The real interest here is the projectors in the line with 3D capabilities. The 3D projector must be paired with a 3D capable computer and with Casio’s proprietary 2D-3D conversion software in order to use this feature. Once that is all set up the hardware will combine a blue laser with its fluorescent element in order to create green light. Some parts of that light are then passed through the red LED’s. This allows the screen to properly shade images to appear 3D, in a style similar to the older optical lens style of 3D instead of trying to project a hologram from multiple angles, as some researchers have been demonstrating in the recent past.

The potential downside to his proposal: the source qubit must be destroyed in the process due to a quantum principle known as the no-cloning theorem26, meaning that it would preclude the possibility (also discussed at GF2045) of having multiple simultaneous instances of oneself in various avatars or other substrates. Then again, the no-cloning theorem has been challenged27 – and the laws of physics being like most things, subject to change, an update may well take place by, say, 2045.

Dr. Theodore Berger: Piecemeal repair and replacement of brain parts is coming. Courtesy of GF2045 The 2011 research paper published by Berger and his co-authors8 states that “A primary objective in developing a neural prosthesis is to replace neural circuitry in the brain that no longer functions appropriately. Such a goal requires artificial reconstruction of neuron-to-neuron connections in a way that can be recognized by the remaining normal circuitry, and that promotes appropriate interaction.” Moreover, the paper notes that “These integrated experimental-modeling studies show for the first time that, with sufficient information about the neural coding of memories, a neural prosthesis capable of real-time diagnosis and manipulation of the encoding process can restore and even enhance cognitive, mnemonic processes.” Already successful on a number of levels, the research intends to provide a hitherto unavailable treatment for damaged brain function, either a result of injury or a result of disease, like Parkinson’s and Alzheimer’s disease – and may, says Berger, be suitable for treating other neurological conditions, including epilepsy. Currently being tested in rats and non-human primates, Berger stated that human trials should begin within the next few years.

Dr. Randal Koene, neuroscientist, neuroengineer and science director of the 2045 Initiative, has been focusing on the functional reconstruction of neural tissue since 1994, introduced the multidisciplinary field of whole brain emulation, and is lead curator of the scientific roadmap with which its technological development is promoted. Working with the VU University Amsterdam, Koene led the creation of NETMORPH, a computational framework for the simulated morphological development of large-scale high-resolution neuroanatomically realistic neuronal circuitry. He is also Founder and CEO of and neural interfaces company NeuraLink Co. In his Whole Brain Emulation: Reverse Engineering A Mind presentation and soon-to-be published book with the same title, Koene describes the process of progressing from our current condition to a possible substrate-independent mind achieved by whole brain emulation and cotes a wide range of research, including the work of fellow GF2045 presenters. “There are several key points to note when discussing substrate-independent minds and whole brain emulation,” Koene tells “First, there’s the importance of understanding the process of iteratively working towards identifying the scope and resolution necessary for whole brain emulation. Second, it’s important to be aware of the fact that we’re on the cusp of a revolution in technology that achieves high-resolution brain activity mapping. Third, we have to be cognizant that much work is still needed in the area of turning data into useful representations and functional systems. Fourth, we need to understand what we are aiming for – that is, only with a good grasp of the goal can you properly set criteria, identify problems and compare possible solutions. Fifth,” Koene concludes, “keep in mind that where whole brain emulation used to be beyond the scope of what was discussed in science labs, it’s now the target for the cutting-edge neuroscience researchers around the world, including those invited to speak at GF2045.”Koene’s presentation and upcoming book also contains recent updates in whole brain emulation, including: A proposal by Michel Maharbiz at UC Berkeley for the development of what he’s termed neural dust – a high density interface to the mammalian brain for wireless neuronal communication, signal detection and recordingThe role of system identification – the iterative process of discovering how an unknown system transforms input into output – in emulating neural tissueHow quantum physics and other candidate mechanisms may or may not be relevant to understanding brain functionThe trade-off between more complex neural data gathering tools and more difficult computational problems A look forward to 2018 – the projected date of successfully emulating the brain of the fruit-fly DrosophilaNew approaches to addressing consciousness and self-awareness”Given these efforts,” Koene tells, “the three most exciting are a June 12, 2013 the National Institutes of Health BRAIN (Brain Research through Advancing Innovative Neurotechnologies) Initiative summit with the explicit aim of 1ms resolution in vivo sampling from every neuron in a brain)11 whole brain emulation being recognized as a valid and desirable research target by the researchers attending the Brain Researchers’ dinner prior to GF2045; and brain activity mapping projects at MIT and UC Berkeley developing microscopic wireless neural interfaces to record vast amounts of data directly from individual neurons.”Dr. Ken Hayworth, who received his doctorate for demonstrating how the human visual system encodes spatial relations among objects13, is Founding President of the Brain Preservation Foundation, Senior Scientist at the Howard Hughes Medical Institute’s Janelia Farm Research Campus, a pioneer in connectomics – the production and study of comprehensive maps of the brain’s neural connections – and an active advocate for whole brain preservation, mind uploading and substrate independent minds. , Physical Review Letters Play Slides: Dr. Theodore Berger: Towards a Hippocampal Neural Prosthesis: Implantable Biomimetic Microelectronics to Restore/Enhance Memory Function.

In Engineering Memories: A Cognitive Neural Prosthesis for Restoring and Enhancing Memory Function, Berger discussed his extraordinary research in the development of biomimetic models of hippocampus to serve as neural prostheses for restoring and enhancing memory and other cognitive functions. Berger and his colleagues have successfully replaced the hippocampus – a component of the cortex found in humans and other vertebrates that transforms short-term memory into long-term memory – with a biomimetic VLSI (Very Large-Scale Integrated circuit) device programmed with the mathematical transformations performed by the biological hippocampus. These transformations, which define the essential memory function of the hippocampus, were first determined through extensive experimental studies of hippocampal neurons and circuits during learning and memory. Then, animals were injected with a drug that suppressed hippocampal function, and thus suppressed new long-term memories. By using one array of electrodes to connect the input of the VLSI chip to the hippocampus (upstream from the damaged region) and a second array of electrodes to connect the output of the VLSI chip to the hippocampus (downstream from the damaged region), the implanted VLSI chip mimics the structure of the nerve tissue in the hippocampus and, in the following sequence, detects incoming neuron activity temporally encoded as short-term memory representations replicates the hippocampal function of transforming this representation into the neural code (or, in Berger’s words, space-time code) used to form long-term memories stimulates electrodes to deliver the appropriate output to the parts of the brain where long-term memories are represented , Proceedings of the National Academy of Sciences Hayworth is also the co-inventor of the Tape-to-SEM process for high-throughput volume imaging of neural circuits at the nanometer scale, and has designed and built several automated machines to implement this process.

This allows the collection of thousands of ultrathin tissue sections on one long continuous plastic film tape with no human intervention. The tissue tape is then stained and imaged in a scanning electron microscope, or SEM.) In addition, Hayworth has envisioned a Connectome Observatory14 as a key milestone for mind uploading.

In terms of animal models and clinical translation9, optogenetics-based research has reportedly led to insights into a range of neurological and psychiatric disorders, including Parkinson’s disease, autism, schizophrenia, drug abuse, obsessive-compulsive disorder, anxiety, and depression. Even more remarkably, in a research paper published just days before this article10, scientists at MIT reported that they “created a false memory in mice by optogenetically manipulating memory engram–bearing cells in the hippocampus,” adding that their data “demonstrate that it is possible to generate an internally represented and behaviorally expressed fear memory via artificial means.” Ray Kurzweil: Immortality by 2045. Courtesy of GF2045 Kurzweil’s brain reengineering approach is based largely on what he terms the Pattern Recognition Theory of Mind (PRTM), which he says describes the basic algorithm used by the neocortex – a brain structure found only in mammals that has evolved into its most complex form in human beings, and where perception, memory, language, reasoning, and abstract thought occur. Kurzweil proposes that the neocortex is hierarchically organized into some 300 million pattern recognizers, each one a 100 neuron cluster arranged in a vertical column, with columns (rather than individual neurons) communicating with one another. His main assertion is that the brain uses these hierarchical pattern recognizers for virtually all aspects of thought, not just for perception.

GF2045 was organized by the 2045 Strategic Social Initiative founded by Russian entrepreneur Dmitry Itskov in February 2011 with the main goals of creating and realizing a new strategy for the development of humanity – one based upon our unique emerging capability to effect self-directed evolution. The initiative’s two main science projects are focused largely on Transhumanism – a multidisciplinary approach to analyzing the dynamic interplay between humanity and the acceleration of technology. Specifically, the 2045 Initiative’s projects seek to (1) enable an individual’s personality to be transferred to a more advanced non-biological substrate, and (2) extend life to the point of immortality – and those skeptical about the likelihood of achieving these goals should consider Arthur C. Clarke’s laws of prediction2: 1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. 2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible. 3.

Courtesy of telexlr8 In his GF2045 talk, Preserving and Mapping the Brain’s Connectome, Hayworth spoke to the concepts and technologies involved in reaching these goals, starting with his central thesis that “our identity is encoded in the structural connections among our brain’s neurons.” In terms of neural imaging, for example, Hayworth points out that with FIBSEM (Focused Ion Beam Scanning Electron Microscopy) – one type of electron microscopy neuroscientists commonly use – preserved neural tissue can be visualized down to resolution of roughly six nanometers, allowing researchers to directly see each neuron’s synapses and dendrites. Moreover, this level of detail includes the ability to directly and indirectly (the latter using molecular probes) image elements of the synaptome – the number and types of special proteins, receptors and neurotransmitters involved in long-term learning and memory – at each synapse; and the epigenome, (learning-based DNA methylation and histone modifications) in the nucleus of each neuron. The outstanding question, says Hayworth, is precisely which features of the synaptome and epigenome need to be preserved to retain memory and identity in each species. That said, he adds, our ability to scan and verify is also rapidly improving through new types of electron microscopy, such as Cryo-TEM (Cryogenic Transmission Electron Microscopy), that can image at a resolution of three angstroms – 50 times greater FIBSEM – where brain proteins and even individual atoms can be directly seen. , PLoS ONE Explore further Dr. Ken Hayworth: GF2045.

Researchers devise broadbandwidth amplifier that ups gain by more than 10 db

first_img Citation: Researchers devise broad-bandwidth amplifier that ups gain by more than 10 db (2014, October 23) retrieved 18 August 2019 from Explore further © 2014 ( —A team of researchers with members from the University of California and Lawrence Berkeley National Laboratory has developed an improvement to a broad-bandwidth amplifier that detects microwave photons allowing them to up the gain by more than 10 db. In their paper published in the journal Physical Review Letters, the team describes the idea behind their amplifier and how it might be used in future superconducting applications. Finnish team devise nanomechanical microwave amplifier with near least possible noise generation The purpose of the newly developed amplifier, like those before it, is to determine the state of a quantum bit in a superconducting device—it’s done by applying a microwave tone. A Josephson parametric amplifier (JPA) is used inside to allow for using a very weak tone in the process. The JPA is actually an oscillating resonator that has a Josephson conductor. This arrangement allows researchers to read a qubit without destroying its state information, as it happens in real time, and in certain circumstances, to actually control it.The goal of the work by the team was to devise a way to overcome the problem of phase mismatch in JPAs so that they could achieve a higher gain over a broad bandwidth. They used a technique known as “resonant phase matching” to up the gain in their JPA—which was achieved by adding several resonating elements into the transmission line. The amplifier is part of an effort by researchers to read and control qubits in superconducting materials, which can involve measuring a single photon in a microwave signal. The result was a design for an amplifier that could be used to create a small device consisting of a transmission line that included subwavelength resonant inclusions that could achieve a gain of 20 dB, saturation power of −98  dBm and a bandwidth of 3 GHz.The Josephson junction type at the heart of the amplifier is typically made by placing an insulator between two superconducting materials. The JPA serves as an inductor serving in the role of a modulated parameter when it’s pumped by a microwave signal.The next step for the team will be creating a device that uses their new amplifier to perform actual measurements of qubits in a superconducting system, possibly taking measurements in a cryogenic broadband microwave application.center_img More information: Resonant Phase Matching of Josephson Junction Traveling Wave Parametric Amplifiers, Phys.

Waiting periods reduce deaths from guns study suggests

first_img Citation: Waiting periods reduce deaths from guns, study suggests (2017, October 17) retrieved 18 August 2019 from Explore further (—A trio of researchers with Harvard Business School has found evidence that they claim shows gun deaths decline when states enact waiting period laws. In their paper published in Proceedings of the National Academy of Sciences, Michael Luca, Deepak Malhotra and Christopher Poliquin describe their study and discuss their results. More information: Michael Luca et al. Handgun waiting periods reduce gun deaths, Proceedings of the National Academy of Sciences (2017). DOI: 10.1073/pnas.1619896114AbstractHandgun waiting periods are laws that impose a delay between the initiation of a purchase and final acquisition of a firearm. We show that waiting periods, which create a “cooling off” period among buyers, significantly reduce the incidence of gun violence. We estimate the impact of waiting periods on gun deaths, exploiting all changes to state-level policies in the Unites States since 1970. We find that waiting periods reduce gun homicides by roughly 17%. We provide further support for the causal impact of waiting periods on homicides by exploiting a natural experiment resulting from a federal law in 1994 that imposed a temporary waiting period on a subset of states. Gun laws requiring domestic abusers to surrender firearms could save lives There is no debate regarding the numbers of people that are killed each year in the United States from bullet wounds—good records exist. The average is now up to 33,000 each year. What remains up for debate is what to do about it. Some individuals and groups have proposed enacting laws restricting gun sales, while others vehemently object to any such restrictions, citing their right to bear arms as spelled out in the Constitution. Somewhere in the middle, there are possible ways to reduce gun violence by enacting less restrictive laws. One such approach is to mandate that anyone buying a gun must wait a specified number of days after the purchase before taking possession of it. The idea is that a waiting period reduces murders and suicides because it gives those gun buyers time to cool off and think a little bit more about their plans before obtaining a gun. Unfortunately, evidence of whether this actually happens has been scant because the U.S. government has enacted laws disallowing the government from funding studies seeking answers to such questions. In this new effort, the researchers circumvented that problem by asking for and receiving funding directly through their own institution.The study consisted of two parts: The first looked at differences in gun death rates between states that had waiting periods and those that did not over the period between 1970 and 2014. The second part consisted of looking at changes in gun death rates in states that enacted waiting periods after passage of the Brady Handgun Violence Prevention Act in 1994, which essentially forced all states to enact waiting periods.Results from the first part of the study showed on average 17 percent fewer gun-related deaths for states with a waiting period (and approximately 10 percent fewer gun-related suicides). Results from the second part of the study nearly mirrored the first—the trio found that gun-related homicide deaths following passage of the Brady Bill dropped on average 17 percent while gun-related suicides dropped approximately 6 percent.The researchers suggest their findings indicate that if the U.S. were to implement a nationwide waiting period for gun purchases, the country as a whole could reduce annual gun deaths by approximately 1,700 a year.center_img Journal information: Proceedings of the National Academy of Sciences © 2017 Credit: CC0 Public Domain This document is subject to copyright.

Study suggests use of genderneutral terms to describe people leads to gender

first_img Explore further Journal information: Proceedings of the National Academy of Sciences Citation: Study suggests use of gender-neutral terms to describe people leads to gender equality (2019, August 6) retrieved 18 August 2019 from More information: Margit Tavits et al. Language influences mass opinion toward gender and LGBT equality, Proceedings of the National Academy of Sciences (2019). DOI: 10.1073/pnas.1908156116 Back in 2012, people in Sweden began debating adding a new word to their language to describe people in a gender-neutral fashion. The language already had the words hon and han, for he and she respectively—the word hen was proposed to describe people without referring to their gender. By 2015, use of the new word had become commonplace, and was added to the Swedish Academy Glossary. In this new effort, the researchers wondered if widespread use of the word in Sweden had reduced male bias in general references, thereby leading to greater gender equality. To find out, they carried out three experiments that involved writing assignments by over 3000 volunteers.In the first experiment, volunteers looked at a picture showing an androgynous character walking a dog. Each was then asked to use the familiar hon or han or the new word, hen, to describe the action in the picture. In the second experiment, volunteers completed a short story about a person of unknown gender running for office. The final experiment involved soliciting volunteers’ views on women and non-males in general (LGBT and non-binary people).The researchers report that those people who used the new word, hen, to describe the dog-walking picture were less likely to use a male name for their character. They also found that people took the same amount of time to write the story about the person running for office regardless of the term they used to describe them. And they found that people who used the new word showed more positivity towards LGBT people. They conclude by suggesting that the introduction of the new word into the Swedish lexicon has led to more gender-inclusive language. They further suggest that such inclusiveness could be leading to less gender bias and the promotion of gender equality. This document is subject to copyright.

Denver area sees more school shootings by population than nations largest metro

first_img— Tuesday’s shooting at STEM School Highlands Ranch, which ended with one student dead, eight others injured and two of their classmates in custody, prompted Coloradans to once again question whether these types of mass shootings are more prevalent here than elsewhere. Ultimately, it’s nearly impossible to be sure if a place is at a higher risk going forward, said Frank Farley, a professor of psychological studies in education at Temple University in Pennsylvania. “If you had suggested to anyone behind me or in this room that, within 20 years in 20 miles, we would have dealt with Columbine, the Aurora theater, Arapahoe High School, the shooting of Zack Parrish and four other deputies, we’d have thought you mad,” he said. “And yet here we are again.”center_img During a 6 a.m. news conference the day after Colorado’s latest school shooting, District Attorney George Brauchler made a point of declaring the tragedies that have rocked the area in recent years don’t define the “kind, compassionate, caring people” who live here. If Columbine did place the Denver area at a higher risk for future shootings, the only thing parents and schools can do is consider responses, like increasing school security and reducing access to weapons, he said.

Its all rain and dance in the city

first_imgBlending in world music with the rhythms from Kerala, Indian Council for Cultural Relations (ICCR) has organised a one of its kind choreographic production, Rain by Vijaylakshmi on 5 July.Rain is a new choreographic work in Mohiniyattam by Vijayalakshmi, the renowned Mohiniyattam dancer. This production is inspired by poet Sudeep Sen’s critically-acclaimed book of poetry, Rain. One of the verse from his book reads: ‘It is raining again, but today’s is a beautiful kind of rain…. steady, symmetrical confident, and unobtrusive. It has a kind of presence that is omnipresent without acutely announcing that it is there, like ambient music.’ Also Read – ‘Playing Jojo was emotionally exhausting’Infusing its essence into a dance form, Vijayalakshmi interprets Rain through the idiom of Mohiniyattam, the south Indian classical dance, which through its fluidity and ability to convey emotions and moods is very suited to express the metaphor of rain.As with most of her path breaking productions, the musical arrangement in Rain is very unique.She has worked very closely with Mac Quayle, an eminent American composer, to arrange traditional Kerala rhythms, Dhrupad, Rabindra Sangeet and contemporary elements which are all brought together seamlessly into a unique blend of world music. Also Read – Leslie doing new comedy special with NetflixIt is perhaps for the first time that Dhrupad has been incorporated into a Mohiniyattam choreographic work, rendered by the eminent torch-bearer of Dhrupad tradition, Wasifuddin Dagar.This vision was furthered by her collaboration with artistic director, Sara Baur-Harding, who also directed the documentary film on Vijayalakshmi and her mother, Beyond Grace and the 3D short film Carmen. Vijayalakshmi has always endeavoured to take Mohiniyattam to higher levels by constantly exploring uncharted territories and expanding traditional boundaries through innovative choreographies inspired from a pan-Indian and global perspective. A recipient of several prestigious national awards, she has carved a distinct niche for herself and has played a significant role in the rejuvenation of this beautiful Indian classical dance form.Head over and experience a confluence of forms.last_img read more

A biography in montage

first_imgArab filmmaker Rania Stephan’s first feature film that sheds light on the life of Egyptian star  Soad hosni will be screened in the Capital this month. The Three Disappearances of Soad Hosni is Rania Stephan’s attempt to tell the story of Soad Hosni, one of Egypt’s most famous film stars who starred in eighty-two feature films between 1959 and 1991. Stephan’ first feature film will be showcased in the capital from 3 to 18 August in the Capital.  Using the technique of filmic montage, Rania Stephan creates a moving portrait of the iconic actress, in which the rumours surrounding her life and death are translated through her image as a projection of the Arab imaginary and its evolution over thirty years. Soad Hosni had fallen from a building on London’s Edgeware Road in 2001. Also Read – ‘Playing Jojo was emotionally exhausting’The film was awarded a Sharjah Biennial Prize in 2011. According to Stefan, ‘The entire film is made from images and sound taken from Hosni’s films. It is built like a tragedy in three acts that ends in death. The film operates like a kind of pre-vision on the tragic destiny of this actress’.Stephan’s film is also a celebration of popular Egyptian cinema, historically sidelined by both Arab critics and the West. ‘I wanted to give popular culture its credence, its value’, says Stephan. Also Read – Leslie doing new comedy special with NetflixBorn in Beirut – Lebanon, Rania Stephan graduated with a degree in Cinema Studies from Latrobe University in Melbourne, Australia and a graduate degree in Cinema Studies from Paris VIII University, France.

Honouring the Maestro

first_imgTo continue the legacy of Sumitra Charat Ram, the illustrious arts patron, who founded Shriram Bharatiya Kala Kendra in 1952, her daughter, Shobha Deepak Singh, has kept alive her mother’s memory through an award instituted by the Kendra. Instituted to be alternatively given to musicians and dancers with at least 30 years of art practice, the award honours the stalwarts of performing arts. This year, Pandit Jasraj was felicitated with the Sumitra Charat Ram Award for Lifetime Achievement on 17 November, at the capital’s Kamani Auditorium. Union Finance Minister Arun Jaitley, presented the award. Also Read – ‘Playing Jojo was emotionally exhausting”I initiated the award to create a benchmark that custodians of Indian cultural forms will value, carrying forward global legacies that have taken birth in India. In felicitating the Indian stalwart Pandit Jasraj, undoubtedly the award has found an appropriate recipient of the honour. Earlier, the award has been given to Pt Birju Maharaj, Kishori Amonkar and Mayadhar Raut’ says Shobha Deepak Singh.The event also marks the commencement of the year long celebrations to commemorate Sumitra Charat Ram’s centenary birth anniversary who was born on November 17, 1914 in Meerut. After schooling in Nainital and Allahabad, she joined the Benares Hindu University, headed at that time by Pandit Madan Mohan Malviya, where she was influenced by the thoughts of renowned writers such as Jaishankar Prasad, Mahadevi Verma, Ramdhari Sinha Dinkar and other luminaries. Also Read – Leslie doing new comedy special with NetflixShe herself organised a night-long concert to commemorate India’s new-found independence. Sumitra ji’s biggest passion was for Kathak, her biggest achievement being the resurrection of the dance form under the aegis of the Kendra. Bharatiya Kala Kendra continued to grow from strength to strength. One of its milestones was the establishment of Kamani Auditorium. Today, the institution is a multifaceted organisation that teaches a wide variety of classical Indian dance styles, as well as vocal and instrumental music. Pt Jasraj himself needs no introduction. Born in 1930 in Hissar, Sangeet Martand Pandit Jasraj hails from a family which has produced three generations of musicians belonging to the Mewati gharana. Endowed with a rich and resonant voice, which traverses a range of three and a half octaves, Pandit ji’s style has been characterised by classical purity in delineation of raga, clarity in diction, music laden with bhakti bhava so much so that it touches the hearts of the listeners which is practically the essence of Indian music.

Exploring trading opportunities

first_imgA part of this thought has been converted into action over the years through the efforts put in by India Trade Promotion Organisation (ITPO) by organising India International Trade Fair (IITF), but it certainly didn’t get a breakthrough until recently, when Prime Minister of India, Narendra Modi gave way to the ‘Make In India’ initiative.IITF, an annual celebration of trade and industry, aims to strengthen our bilateral relations with the rest of the world. In the realm of external relations, the government has intensified India’s engagement with it’s neighbours and all friendly countries across the globe for better trade and cultural relations. Also Read – ‘Playing Jojo was emotionally exhausting’Complimenting ITPO, the President of India, Pranab Mukherjee, underlined the contribution of the organisation in providing an ideal platform to SMEs. According to him, the fair, which is an archetype of the modern trade show, is a brand name in itself, enjoying recognition worldwide.This edition of the fair has a tremendous significance, especially when a unique transformation is taking place in the country. Several recent initiatives of the Government have already shown results and a positive impact has been created in key sectors. The ‘Make in India’ initiative will help India become a sought after investment and manufacturing destination. Also Read – Leslie doing new comedy special with NetflixThe 35th edition of India’s largest trade fair has commenced on a high note here, drawing huge crowds to the sprawling Pragati Maidan fairgrounds on the very first day. Some of the sellers attributed the overwhelming response to Prime Minister Narendra Modi’s ‘Make in India’ mantra.LC Goyal, Chairman and Managing Director, ITPO, expressed his gratitude to the President of India for sparing his gracious time and highlighted the salient features of the fair. He informed that IITF 2015 has participation of over 7000 exhibitors from 28 countries as against 6800 exhibitors last year. He also stated that IITF is a 14-day grand festival to celebrate and stimulate Indian trade and commerce, not only within the country but across the globe as well. Aligning with the Government of India policy of Start- Up, ITPO has earmarked Hall No. 26 for start-up enterpreneurs who have been provided a discounted tariff on rentals. ITPO has dedicated itself to ‘Swachh Bharat Mission,’ by introducing a separate award category for the best State Pavilion.Speaking on the occasion, Shaida Mohammad Abdali, Ambassador of Afghanistan, the partner country for the fair, expressed his happiness over the participation of his country as a partner country and stated that India is a strategic partner of Afghanistan.Syed Muazeem Ali, High Commissioner of Bangladesh, the focus country for the fair, appreciated India’s Look East policy which represents its efforts to cultivate extensive economic and cultural relations with the nations of Southeast Asia.Yashodhara Raje Scindia, Department of Commerce, Industry and Employment, Government of Madhya Pradesh, the focus state of the fair, emphasised that Madhya Pradesh, ranked fifth for Ease of Doing Business in India by World Bank, is also laying emphasis on infrastructure development and IT.As a partner country, Afghanistan had its own pavilion at the exposition with around 50 stalls selling handmade jewellery, watches, world renowned Afghani carpets, kaftans, saffron and dry fruits – a hot seller. Aiming at potential women buyers, is the Afghani Lapis Lazuli stoned jewellery. “Considering it’s the start of the fair, we have had a very good sale and have noticed huge numbers of buyers compared to the previous years. India’s push for ‘Make in India’ could be doing the trick,” said Shirin Qahraman, a woman entrepreneur from Kabul. Qahraman’s store has an exclusive collection of Lapis Lazuli neck-pieces, rings and bracelets. The neck-pieces start from Rs 2,000 and go as high as Rs 10,000.For Sado Zai, 32, a retail carpet seller from Kabul, the fair has been extremely helpful in marketing his products across the world. “The trade fair has been enabling us showcase our products to people around the world. I now have a few clients in India who import my carpets regularly. Through Make in India project, we are exploring ways to set up a business here,” said Zai as he exhibited his wares. The Afghani carpets are priced anywhere between Rs 5,000 and Rs 50,000, depending on their size.As enthusiastic were the sellers about the fair, many expressed concern that the rent they have to pay for their stalls has skyrocketed. “For a stall of 10×6 feet, manned by two people, the rent is as high as $4,500 for the (two-week) duration of the fair.

Childhood head injury may up mental illness mortality risk

first_imgThe findings showed that people who had experienced a single mild, moderate or severe brain injury during childhood were at twice the risk of being admitted to hospital as a mental health inpatient (an increase in absolute risk from 5 per cent to 10 per cent).They were 50 per cent more likely to use a mental health service (increase from 14 per cent to 20 per cent) than unaffected people in the same age group.The risk of outcomes, including the likelihood of developing a psychiatric illness, became higher if the injury was more severe, or if there were multiple injuries.

More serious brain injuries and repeated brain injuries made them even more likely,” said lead author Seena Fazel, professor at Oxford University.Further, they were 80 per cent more likely to receive disability benefits (increase from 4 per cent to 6 per cent) and 70 per cent more likely to die before the age of 41 (increase from 0.8 per cent to 1.6 per cent).  Also Read – Over 2 hours screen time daily will make your kids impulsivePeople who had experienced repeated mild, moderate or severe brain injury were over two-and-a-half times more likely to receive disability benefits than contemporaries who had experienced a single-episode injury (increase from 6 per cent to 12 per cent).In addition, there were also 60 per cent more likely to have done poorly at school (increase from 9 per cent to 14 per cent) or be in receipt of welfare benefits (increase from 12 per cent to 19 per cent). “Our study indicates far-reaching and long-term consequences of head injury. It reinforces what we knew already — that prevention is key,” Fazel said. “Existing work to prevent head injuries to young people in sports, for example, needs to be enhanced. Long-term follow up could identify negative effects so that early intervention can prevent a drift into low attainment, unemployment and mental illness,” Fazel suggested in the paper published in the journal PLOS Medicine.For the study, the international team of researchers, analysed data from more than a million Swedes born between 1973 and 1985 to examine the long-term impact of having a traumatic brain injury before the age of 25.The study looked at low educational attainment, instances of psychiatric care, receiving welfare and disability benefit and early death in the participants.The team compared people who had experienced brain injury to unaffected people in their same age group, and also to their brothers and sisters who had not been injured.last_img read more
