Despite the Odisha government’s order to waive all academic fees for physically challenged students, several government and government-aided higher secondary schools are collecting admission fee from them.As per an order of the Department of School and Mass Education of Odisha dated May 25, 2018, ‘all academic fees, except mess charges, will be waived in respect of students with disabilities of 40% or more’. But due to ignorance of authorities of some higher secondary schools, physically challenged students are being pressed to pay up admission fee during admission to +2 courses.Immediate declaration Retired principal of Red Cross School for the Blind in Berhampur, Nabin Chandra Satapathy, has brought this to the notice of the State Commissioner for Persons with Disbilities, Odisha. Mr. Satapathy, who is actively involved in issues related to bind students, demanded that the government make some immediate declaration so that higher secondary schools stop collecting admission fee from blind students during admissions.In his representation, Mr. Satapathy has cited example of three visually impaired students who have passed the tenth board examination from Red Cross School for the Blind, Berhampur, and have got admitted in different higher secondary schools of the State. Receipts of these students clearly state that admission fee was collected from them.This error has happened in top higher secondary institutions of the State like Ravenshaw Higher Secondary School, Cuttack, and Khallikote Higher Secondary School, Berhampur. “Dutikrushna Jena had to pay over ₹4000 to get admitted in +2 first year of arts course in Muniguda Junior College of Rayagada district. Similarly S.Nahak had to pay ₹961 for admission to higher secondary arts course of Ravenshaw Higher Secondary School, Cuttack. Prabhakar Sethi paid ₹1,062 for +2 arts admission in Khallikote Higher Secondary School, Berhampur,” said Mr. Satapathy.
More than 88% of the driving licences issued in Hailakandi district of Assam have come under the scanner.The southern Assam district has 45,300 driving licence holders. A scrutiny during an attempt to convert the laminated paper licences to smart cards revealed that some 40,000 of them could be “doubtful” or procured fraudulently.Last week, Hailakandi’s District Transport Officer Syed Rafiqul Mannan issued an order saying a majority of the licences were purportedly issued by his counterpart in Manipur’s Bishnupur district while the rest were issued by a “certain district” of Nagaland. These licences were flagged as doubtful.Agents to blame? There have been cases of people acquiring driving licences from neighbouring States after their applications were rejected in Assam.The DTO said that most of the people who applied for smart card revealed on being questioned that they did not go to Manipur or Nagaland to obtain their licences. This brought to the fore the issue of bogus driving licences being made with the help of agents.“Data was not available online as most of the licences were of the laminated type. The process of converting them into smart cards was accordingly put on hold. More than 40,000 such licences are lying in my office,” Mr. Mannan said.Smart cards The smart cards would be issued once his counterparts in Manipur and Nagaland confirm the authenticity of the driving licences purportedly issued from their offices, he said.Officials said the licences will be cancelled, as per the Motor Vehicles Act, if they are not found to be genuine. People can reapply online for fresh smart card licences.
Truly a hero. Sony Pictures While many Marvel fans are focused on the epic conclusion to 10 years worth of storytelling in Avengers: Endgame, a team of Israeli researchers are diving back through Marvel’s movie catalog to help people overcome their fears.New research suggests that fear of spiders (arachnophobia) and fear of ants (myrmecophobia) can be alleviated by viewing a seven-second scene from Spider-Man 2 or Ant-Man.The study, published in Frontiers in Psychiatry on April 23, showed 424 participants segments of the Sony Pictures film Spider-Man 2, the Marvel film Ant-Man, a natural scene or the Marvel opening credits scene. Prior to viewing and after viewing they measured the participants’ responses in an online quiz that assessed their socio-demographic variables, familiarity with the films and phobic symptoms.The team showed watching Spider-Man 2 alleviated some of the symptoms of spider phobia. Post-viewing phobia symptoms were decreased, relative to pre-viewing, by 20%. Similar results were seen with Ant-Man.

This method is routinely used by psychiatrists to treat specific phobias by showing the patient neutral, non-harmful images of the things they are afraid of. Exposing them to their fear without consequence gradually helps ease the symptoms of the phobia.To ensure that it wasn’t just the idea of watching a Marvel film that had participants less fearful, the researchers compared their scores to those who watched the Marvel credits or a natural scene. The credits and the natural scene provided no reduction in phobia symptoms after viewing. Thus, the team concluded that Spider-Man and Ant-Man aren’t just incredibly good at fighting the intergalactic bad guys, they’re also beneficial for those suffering specific insect phobias.Notably, they suggest that because of the “fun” nature of Marvel films — and the fact they are such a huge part of modern pop culture — may reduce some of the stigmas associated with treatment and therapy of these phobias.The team is now looking at how they can improve the effects of their Marvel-based treatment option. Their next study will again assess the effect of watching Marvel movies on the brain, with a focus on how it may benefit those with post-traumatic stress disorder. Tags Sony

Adrian Dennis / AFP / Getty Images Vodafone apparently discovered hidden backdoors in Huawei equipment as far back as 2011.The UK-based carrier found vulnerabilities in routers and other equipment that could have given scandal-scarred Chinese company Huawei unauthorized access to Vodafone’s network in Italy, Bloomberg reported Tuesday.Both Vodafone and Huawei told Bloomberg that these vulnerabilities were addressed in 2011 and 2012. However, the outlet reported that the vulnerabilities remained after that and could also be found in Vodafone’s UK, German, Spanish and Portuguese businesses, citing anonymous sources. Vodafone apparently kept using Huawei equipment because it was competitively priced. Huawei P30 Pro’s four rear cameras from every angle Security Internet Services Share your voice Vodafone disputed the report in an emailed statement, saying the “backdoor” mentioned is a protocol used to perform diagnostic functions and wouldn’t have been accessible from the internet.”In addition, we have no evidence of any unauthorized access. This was nothing more than a failure to remove a diagnostic function after development,” the spokesperson wrote. “The issues were identified by independent security testing, initiated by Vodafone as part of our routine security measures, and fixed at the time by Huawei.”Huawei mirrored this statement, noting that it addressed the “historical vulnerabilities” in 2011 and 2012.”Software vulnerabilities are an industry-wide challenge,” a spokesperson said via email. “Like every ICT vendor we have a well-established public notification and patching process, and when a vulnerability is identified we work closely with our partners to take the appropriate corrective action.”Bloomberg didn’t immediately respond to a request for further comment.The story comes as China urges Britain to let Huawei play a role in developing its next-generation 5G wireless network, even as the US pressures its European allies not to adopt Huawei’s 5G equipment. US officials have said the gear could be used to spy for China. Huawei denies the allegations. Comments Now playing: Watch this: 1:11 Huawei Vodafone
One of the early pioneers of LFM was Marc Levoy, who many folks may have heard of due to his groundbreaking work at Google. His many projects include co-designing their book scanner, launching Street View, and contributions Google glass. Together with his collaborators, Marc also refined the techniques that led to the imaging system used in the popular Lytro camera, which like LFM can be refocussed after-the-fact to different parts of an image. To create the LFM they placed a microlens array beyond the specimen at the intermediate image plane of a conventional microscope. Different points on the sample are then recorded in separate small images on a light field plane further above the sample. Deconvolution techniques can then used to build up whole images.While the LFM has been used before for in-vitro imaging, Ed’s new work represents the first time that spatial resolutions comparable to the groundbreaking zebrafish brain activity maps (courtesy of Misha Ahrens) have been presented. I asked Ed how his new work in imaging the entire c. elegans worm compares with the light sheet methods used by Ahrens and company. He stressed that eliminating the physical component, (the actual scan) is the key to the superb temporal resolution now possible, and that the deconvolution algorithms yield the improved spatial resolution. While the zebrafish results were acquired in a volume 800x600x200 microns per side, with an impressive lateral resolution of 0.65 um, the refresh rate was a relatively slow 1.3 seconds. With Boyden’s LFM, the imaging volume used was slightly smaller (~350 μm x 350 μm x 30 μm) although that is fine here because basically, the entire nervous system of the worm, in fact most of its body, could fit in that volume. The resolution was a respectable ~1.4μm in the lateral dimension and 2.6μm in the axial, still good enough for single neuron precision. The impressive thing here though is the whole volume image rate—up to 50 hz. That is fast enough to shift the temporal resolution problem away from the hardware, and put it back in the laps of the chemists that make the dyes or protein sensors used for imaging.

Last year’s fascinating images of a zebrafish watching its lunch swim by as a cerebral doppelganger of fish activity percolated eerily through its own brain was proof enough of this. Ed and his group were already able to image the complete set of head ganglia neurons in the worm at the same time selected ventral cord control units were imaged, not a bad start. Not having any real experience myself, as far as how these techniques are actually implemented into the experimental workflow, I asked neurophysiologist David Schoppik to comment here. In his words:”This work from the Vaziri and Boyden laboratories is both important and exciting, and is a nice complement to ongoing work in the Levoy lab (Broxton et. al., 2013). While a light-field microscope can acquire data breathtakingly quickly, processing times of 20-90 minutes/frame (i.e. weeks of processing to analyze a couple minutes of acquired data) limits its applicability. As hardware and algorithms mature, this is sure to improve. Perhaps most excitingly, as the next generation of genetically-encoded voltage sensors comes online, light-field microscopy unique holds the promise of acquisition of large volumes with the speed necessary to capture membrane potential dynamics.”To David’s point, we are already beginning to see some of these next generation voltage sensors take shape. Intriguing work on multi-state “Flash Memory” sensors that can be toggled on and off by different wavelengths of light have just been published. Some of the fancier techniques, like direct genetic encoding, enable the sensor to be targeted to just a small number of specific cells. This is crucial so that the total number of signal producers in the field of view is not so large that everything is bright. At the same time however, as we have learned using techniques like Brainbow II, if you only have labelled synapses, you don’t have the whole picture. Glia, blood vessels, and organelles are all critical pieces of the puzzle.However now, we are beginning to understand that much of the larger activity of the nervous system, particularly at the periphery, is not something we can readily comprehend in isolation from the immediate tissue in which it embeds. Something as simple as tactile sensing in the worm, whether by raw nerve ending or whatever version of a vibratory corpuscular sensor a worm might possess, are really larger chemo-mechanical issues that extend beyond nerve membranes. Imaging the entire body of the worm, down to the level of movements of cell organelles should give a fuller picture of integrated activity beyond transient calcium or voltage spikes.If functions like adaptation and memory, as many now believe, involve structurally observable change—actual motions by and within cells—then perhaps these slower dynamics will come to be appreciated on par with the faster spikes associated more with direct signalling. The previously unimagined abilities of cells (including neurons) to target and exchange mitochondria, for example, might be imaged in worms and correlated directly to spiking activity. It may be a slight digression from microscopy techniques, but if we consider an extreme case of organelle transport, we might have some guidance for what to look for in new experiments. The 10-meter long motor axons of the blue whale, for example, need to provide fresh organelles that offer proteins and power to the end effectors where they are needed. However doing this on any kind of timescale relevant to spikes or synaptic modifications is not just difficult, it is impossible. Slow phase axonal transport would take decades to reach their muscle target points, while even the fast component pool (perhaps several mm/day) would still take months. Furthermore, consider here that during the growth phase, the whale axons tethered to the fluke region are being pulled aft at the astounding rate of 3cm per DAY. That imposes a huge “volume debt” that must be satisfied by some source of cellular materials.The point of this diversion is that if in larger creatures, neurons are materially isolated from their targets on the timescales of electrical activity, than local tissue interactions, like sharing mitochondria and other packages of genetic information, most be significant. For now, the humble worm, together with these new LFM methods offers an ideal platform to further probe these kinds of activities from the molecular to tissue level. As they give way to in vivo imaging of larger brains, nerves, and bodies, we should have a clearer picture of what we might count as “activity” in the full functional map of a calculating organism. Capturing brain activity with sculpted light © 2014 Phys.org More information: Simultaneous whole-animal 3D-imaging of neuronal activity using light field microscopy, arXiv:1401.5333 [physics.optics] arxiv.org/abs/1401.5333Abstract3D functional imaging of neuronal activity in entire organisms at single cell level and physiologically relevant time scales faces major obstacles due to trade-offs between the size of the imaged volumes, and spatial and temporal resolution. Here, using light-field microscopy in combination with 3D deconvolution, we demonstrate intrinsically simultaneous volumetric functional imaging of neuronal population activity at single neuron resolution for an entire organism, the nematode Caenorhabditis elegans. The simplicity of our technique and possibility of the integration into epi-fluoresence microscopes makes it an attractive tool for high-speed volumetric calcium imaging. (Phys.org) —Advances in light-sheet microscopy have led to impressive images and videos of the brain in action. With this technique, a plane of light is scanned through the sample to excite fluorescent calcium sensors which proxy neural activity. While the transparent head of a baby zebrafish, or even the whole body of a tiny worm can now be mapped with impressive lateral resolution, the temporal resolution is still limited by the need for the scanning. A potentially much more powerful technique—light field microscopy (LFM)—gets rid of the moving parts and can therefore create volumetric images in a fraction of the time. Ed Boyden and his collaborators have now tuned these methods to create the first “functional LFM images” of the brain. Their results have just been published to the Arxiv preprint server. C. elegans.
