(University of Central Florida) Cell biologists at the University of Illinois at Urbana-Champaign and Bar-Ilan University at Israel and a bioimaging expert at the University of Central Florida are teaming up in what they hope may lead to a major breakthrough in understanding of the three-dimensional organization of the nucleus over time and their role in certain diseases.
(Bar-Ilan University) With the addition of just a small number of autonomous vehicles (AVs) on the road, traffic flow can become faster, greener, and safer in the near future. Researchers from Bar-Ilan University present a simple set of guidelines and regulations for achieving the self-organization of AVs into constellations that dynamically control the entire traffic flow even when fewer than 5% of the vehicles on the road are autonomous.
(Bar-Ilan University) Researchers have introduced a new type of MTJ with four resistance states, and successfully demonstrated switching between the states with spin currents. The increased number of states is achieved by replacing one of the magnetic layers with a structure in the form of two crossing ellipses. Such MTJs may enable novel spintronics devices, e.g., multi-level MRAM which stores data much more densely, or neuromorphic memory that meets artificial intelligence challenges in performing cognitive tasks.
(Bar-Ilan University) A group of Israeli researchers recruited 16 violinists to study the behavior of a human network and find out what sets it apart from other networks, such as animals, computers and other objects. The results combine science and aesthetics and also evoke thoughts about the spread of the coronavirus.
(Bar-Ilan University) After tracking a cohort of community members equipped with naloxone and a smartphone application for more than a year, researchers showed that laypersons can effectively signal and respond to overdose incident to administer nasal naloxone in advance of emergency medical service (EMS) arrival. Just as CPR and early defibrillation administered by laypersons in advance of EMS contribute to positive outcomes after cardiac arrest, so, too, can opioid patients benefit from similar forms of community support.
Random bit sequences are key ingredients of various tasks in modern life and especially in secure communication.In a new study researchers have determined that generating true random bit sequences, classical or quantum, is an impossible mission.Based on these findings, they have demonstrated a new method of classified secure communication.The mathematical definition of a random bit sequence is so simple that it can be summarized in one sentence: A sequence of bits whose next bit is equal to 0 or 1 with equal probability, independent of previous ones.Although the definition is very simple, the practical certification of a process as random is much more complicated but crucial, for example, in secure communication, where information must be scrambled in order to prevent hackers from predicting a bit stream.In an article to be published on November 5, 2019 in the journal Europhysics Letters, researchers at Bar-Ilan University demonstrate that long sequences with certified randomness by the US National Institute of Standard and Technology (NIST) are far from being truly random.
Machine learning, introduced 70 years ago, is based on evidence of the dynamics of learning in our brain.Using the speed of modern computers and large data sets, deep learning algorithms have recently produced results comparable to those of human experts in various applicable fields, but with different characteristics that are distant from current knowledge of learning in neuroscience.Using advanced experiments on neuronal cultures and large scale simulations, a group of scientists at Bar-Ilan University in Israel has demonstrated a new type of ultrafast artifical intelligence algorithms -- based on the very slow brain dynamics -- which outperform learning rates achieved to date by state-of-the-art learning algorithms.In an article published today in the journal Scientific Reports, the researchers rebuild the bridge between neuroscience and advanced artificial intelligence algorithms that has been left virtually useless for almost 70 years."The current scientific and technological viewpoint is that neurobiology and machine learning are two distinct disciplines that advanced independently," said the study's lead author, Prof. Ido Kanter, of Bar-Ilan University's Department of Physics and Gonda (Goldschmied) Multidisciplinary Brain Research Center."The number of neurons in a brain is less than the number of bits in a typical disc size of modern personal computers, and the computational speed of the brain is like the second hand on a clock, even slower than the first computer invented over 70 years ago," he continued.
Also, one man launched a legal battle against the police for using facial recognition cameras in the UKRoundup Hello, here's a quick roundup of recent machine learning tidbits that you can digest after the long weekend.The police have been trialing the technology across the UK for a while now and the results haven’t been great.Ed Bridges, a resident of Cardiff in Wales, reckons his face was snapped during a peaceful anti-arms trade protest when he was out doing a bit of Christmas shopping.Goldberg and the gang will be focused on natural language processing (NLP).It has several NLP projects ranging from Aristo, a system that helps dissect scientific research papers, to Semantic Scholar, a machine learning search engine to help people find the find the relevant papers to read.
The field of genetic sequencing has undergone a dramatic revolution over the past 20 years.In 2001 the first copy of the three billion base pairs that assemble the human genome was published.Many studies focus on identification of genetic patterns and genes related to normal functions and disease.However, certain genomic regions are still poorly characterized.In a study published today in the journal Nature Communications, a team of researchers, led by Prof. Gur Yaari, of the Alexander Kofkin Faculty of Engineering at Bar-Ilan University, reveals a novel computational tool it has developed to study variations in genes that determine the immune system's dynamics and used to analyze genetic variation among 100 individuals.Current knowledge of the regions which determine the immune system's function is very limited.
Every year, they’re responsible for tens of thousands of fatalities and hundreds of millions of displaced homeowners.Accurate flood forecasting is a desirable goal, needless to say; according to some studies, early warning systems can reduce deaths and economic damages by over a third.Fortunately, it’s one scientists continue to inch toward with the help of artificial intelligence (AI).In a new paper (“ML for Flood Forecasting at Scale“) published on the preprint server Arxiv.org, researchers from Google, the Israel Institute of Technology, and Bar-Ilan University describe a machine learning system that accurately predicts riverine floods — that is, floods from overrun riverbanks.And it builds on research published by Harvard and Google in August 2018, which described an AI model capable of predicting the location of aftershocks up to one year after a major earthquake, and by Facebook AI researchers in December, who developed a method to analyze satellite imagery and quantify damage from fires and other disasters.“Effective riverine flood forecasting at scale is hindered by a multitude of factors, most notably the need to rely on human calibration in current methodology, the limited amount of data for a specific location, and the computational difficulty of building … models that are sufficiently accurate,” the team wrote.
Hair-thin optical fibers support measurements over hundreds of km, may be embedded in almost any structure, operate in hazardous environments and withstand electro-magnetic interference.Recently a major breakthrough in optical fiber sensors facilitated the mapping of liquids outside the boundary of the glass fiber, even though guided light in the fiber never reaches there directly.Such seemingly paradoxical measurements are based on the physical principle of opto-mechanics.These ultrasound waves, in turn, can probe the surroundings of the fiber, similar to ultrasonic imaging that is common in medical diagnostics.Without such protective coating, or "jacket" as it is often referred to, bare fibers of 125 micro-meters diameter do not stand much chance.One cannot consider the application of kilometers-long, unprotected optical fibers outside the research laboratory.
The European Union (EU) and the Canadian government have awarded the international iReceptor Plus consortium, which is composed of more than 20 partners, €8.65 million to promote human immunological data storage, integration and controlled sharing for a wide range of clinical and scientific purposes.The four-year project aims to develop an innovative platform to integrate distributed repositories of Adaptive Immune Receptor Repertoire sequencing (AIRR-seq) data for enabling improved personalized medicine and immunotherapy in cancer, inflammatory and autoimmune diseases, allergies and infectious diseases.iReceptor Plus will enable researchers around the world to share and analyze huge immunological datasets taken from healthy and ill patients that have been sequenced and stored in databanks in multiple countries.The project has received €7.85 million from the EU through the Horizon 2020 Research and Innovation Programme and an additional €800,000 from the Canadian government."Most AIRR-seq data is currently stored and curated by individual labs, using a variety of tools and technologies," said Bar-Ilan University Associate Professor Gur Yaari, of the Alexander Kofkin Faculty of Engineering, who is the initiator and coordinator of the iReceptor Plus Project."The platform will lower the barrier to access and analyze large AIRR-seq datasets and will ease the availability of this important data to academia, industry and clinical partners."
Advances in the technology of material growth allow fabricating sandwiches of materials with atomic precision.For example, a magnetic interface found between two non-magnetic materials.Using very sensitive magnetic probes, an international team of researchers led by Prof. Beena Kalisky, of Bar-Ilan University's Department of Physics and Institute of Nanotechnology and Advanced Materials (BINA), has found surprising evidence that magnetism which emerges at the interfaces between non-magnetic oxide thin layers can be easily tuned by exerting tiny mechanical forces.Magnetism already plays a central role in storing the increasing amount of data produced by humanity.Much of our data storage today is based on tiny magnets crammed into our memory drive.One of the promising means in the race to improve memory, in terms of quantity and speed, is the use of smaller magnets.
A test in sheep shows that custom-made electrodes can constrict an injured artery and reduce blood lossOur precious arteries are encased in three layers of protective cells—something to be grateful for, considering that injured vessels can cause an adult to bleed to death in fewer than five minutes.Now, a novel short-term approach for closing a hemorrhaging artery is one step closer to helping humans, as researchers have shown that pulses of electricity can make an injured artery constrict, ultimately reducing blood loss.A team led by Yossi Mandel of Bar-Ilan University, successfully demonstrated this approach in sheep; their results were published on 23 November in IEEE Transactions on Biomedical Engineering.“Bleeding control is, of course, one of the main aims of every army,” he says.“There were some preliminary reports on the effect of electric fields on blood vessels and I wanted to further explore this phenomenon and its translational potential for treating patients and soldiers wounded in the battlefield.”
They are fine threads of glass, as thin as a human hair, produced to transmit light.Optical fibers carry thousands of Giga bits of data per second across the world and back.In contrast, ultrasonic waves can reach the outer boundaries of fibers, and probe their surroundings.Intuition, and much of the training given in fundamental undergraduate classes in mechanics and optics, instructs to consider light and sound waves as separate and unrelated entities.Light and sound waves can interact/affect one another and aren't necessarily separate and unrelated.Such studies, especially on fibers, can be very useful and bear surprising results.
A phenomenon that stands at the core of this development is the Quantum phase transition.Ice melts at zero degrees Celsius and evaporates at a hundred degrees.How cool would it be if instead of heating water in a kettle for a cup of tea we could take a glass of cold water and boil it by bringing it close to a magnet!These transitions are not driven by the temperature, but by changing a different physical property such as mechanical pressure or magnetic field.This principle, developed by German physicist Werner Heisenberg, states that contrary to our intuition, vacuum is not empty but contains temporary changes in the amount of energy in a point in space.Though indirect evidence for their presence appears in many measurements, no one has actually seen them.
Researchers who study and manipulate the behavior of materials at the atomic level have discovered a way to make a thin material that enhances the flow of microwave energy.The advance, which could improve telecommunications, sheds new light on structural traits, generally viewed as static and a hindrance, that, when made to be dynamic, are actually key to the material's special ability.The discovery, reported in the journal Nature, shows how domain walls - the naturally occurring boundaries, separating atoms with different directions of relative displacement, that create dipoles within a material - could actually be an entryway for accessing a much wider range of electromagnetic frequencies.In the paper, researchers from Drexel University, Bar-Ilan University in Israel, the University of California at Berkeley, the University of California at Santa Barbara, the Carnegie Institution for Science, and the University of Pennsylvania showed how a ferroelectric material can be designed in such a way that domain walls can be used to transmit microwaves with a higher degree of frequency control than the mobile devices we currently use."Tunable dielectric materials could be a potential solution."Using the domain walls within a material to enhance its transmission quality is a particularly unexpected approach because the presence of these boundaries tends to strongly diminish a material's ability to pass a microwave electromagnetic field.
Whether it’s heart rate, breathing rate or muscle activity, there are wearable devices that are capable of measuring just about biometric data point you can think of.That is something researchers from Israeli startup ContinUse Biometrics have been working on.Their resulting device — capable of monitoring these vital signs from meters away — is set to hit shelves as soon as the end of 2018.And it all works thanks to the wonder of lasers.“The technology has been investigated for eight years in my lab, in collaboration with the lab of Professor Javier Garcia from Valencia, Spain,” Zeev Zalevsky, professor of electrical engineering and nanophotonics at Israel’s Bar-Ilan University, told Digital Trends.“Two years ago, it was commercialized to ContinUse Biometrics, which is going to release its advanced prototypes toward the end of 2018.
Experts in Israel have found the earliest evidence of ancient “blood vengeance” in a cave in the Jerusalem Hills.A human skull and palm bones were found in the cave by Boaz Zissu, an archaeology professor at Israel’s Bar-Ilan University.Experts from the Israel Antiquities Authority and Tel Aviv University identified the bones as belonging to a man aged between 25 and 40 years."The skull cap shows signs of two traumatic injuries that eventually healed -- evidence of previous violence experienced by the victim -- as well as a small cut-mark caused close to the time of death, and a blow by a sword that caused certain and immediate death,” the researchers said, in a statement.An examination of the skull revealed a great resemblance to the local Bedouin population, which apparently had a tradition of blood vengeance, even before the birth of Islam, according to the experts.Archaeologists cited a text from the beginning of the 20th century that tells the story of a case of revenge, during which the murderer presented his family with the skull and right hand of the victim by way of proof.
Archaeologists in Israel have uncovered an ancient site that may offer fresh insight into the ancient biblical kingdom of David and Solomon.The impressive four-room home, located at Tel ‘Eton in the Judean foothills, had at least two stories and its ground floor extended over 2,420 square feet.Occupying high ground at the top of a mound, the house was carefully built with deep foundations.Large masonry stones were placed in the corners and entrances of the building and high-quality building materials were used, according to experts.While some experts believe that the kingdom existed in the 10th-century B.C., others have questioned its existence, citing a lack of evidence of royal construction at the center of the region where the kingdom is said to have existed.However, part of the building at Tel ‘Eton has been dated to a period in history that coincided with the supposed joint kingdom, according to Prof. Avraham Faust and Dr. Yair Sapir.
