Harvard, Stanford, MIT top 2015 Shanghai Ranking, Hebrew U 67th, Technion 18th in CS

Sunday, August 16th, 2015

(JNi.media) Harvard University is still number one in the world, for the 13th year, in the 2015 Academic Ranking of World Universities (ARWU) released on Saturday by the Center for World-Class Universities at Shanghai Jiao Tong University.

Harvard is followed by Stanford, MIT, Berkeley, Cambridge, Princeton, Caltech, Columbia, Chicago and Oxford. The Hebrew University of Jerusalem ranks 67th, after having dropped in 2014 from 59th to 70th place.

The Technion-Israel Institute of Technology is ranked 18th in the world in computer science in 2015.

Starting in 2003, ARWU has been presenting the world Top 500 universities annually, based on a set of objective indicators and third-party data. It is considered a trustworthy source, using six objective indicators to rank world universities, including the number of alumni and staff winning Nobel prizes and Fields medals; the number of highly cited researchers; the number of articles published in journals of nature and science; the number of articles indexed in Science Citation Index – Expanded and Social Sciences Citation Index, and per capita performance.

More than 1200 universities are ranked by ARWU every year and the best 500 scores are published.

The Technion is in 77th place on the list of world academic institutions. Tel Aviv University ranks between 151-200, alongside Weizmann Institute of Science. Ben-Gurion University of the Negev ranks between 401-500.

Haifa University did not make the top 500 institutions.

Yeshiva University was ranked between 201-300. Yeshiva’s ranking has been on a steady decline in the Shanghai ranking, down from the 100-200 band in 2003-4. The only area where Yeshiva has retained its 151-200 ranking in 2015 is clinical medicine and pharmacy.

The top world academic institution in natural sciences and mathematics in 2015 is the University of California, Berkeley, followed by Harvard, Princeton and Stanford Universities. The Technion ranks in the 51-75 band, together with Hebrew University and the Weizmann Institute of Science. Tel Aviv University ranks in the 101-150 band.

The top world academic institution in computer science in 2015 is Stanford University, followed by MIT, UC Berkeley, Harvard, Princeton, Carnegie Mellon, the University of Texas at Austin, Cornell, UCLA, and USC.

The 18th ranked Technion is followed by Tel Aviv University which ranks 20th in computer science, and the Hebrew U and Weizmann which are in the 76-100 band in the same category. Ben-Gurion is in the 101-150 band. Bar-Ilan University is in the 151-200 band in computer science.

Israeli Eye Surgery Breakthrough Uses Stitch-free Cornea Transplants

Tuesday, July 7th, 2015

An Israeli scientist at Tel Aviv University has developed a new optical fiber that can seal incisions in the eye without using stitches.

The procedure will radically change the way cornea transplants are performed, cutting short the long, drawn-out painful recovery period.

Professor Avraham Katzir, head of the Applied Physics Group at the university’s School of Physics and Astronomy, suggested a new technique called “temperature-controlled laser bonding” for use in sealing the incisions in eye surgery. The technique is described in a recent issue of the Journal of Biomedical Optics.

Using optical fibers made of silver halides to deliver an infrared laser beam, the surgeon can carefully heat spots on the edges of an incision where an infrared detector helps monitor the temperature, keeping it between 140 to 150 degrees Farenheit. This creates a strong bond without causing thermal damage, according to the researchers.

Katzir has already received approval to conduct experiments with the procedure on live animal models.

Medical science is moving towards the least invasive model, he says. This technique can be used – and he has tried it – in endoscopic surgery as well. Using thin and flexible optical fibers inserted through the endoscope to facilitate laser bonding within the body, healing is faster and more successful, with “almost no scar tissue.”

There is a broad future ahead for this technique, Katzir pointed out. Fiber optic laser surgery can be used in endless applications.

Israeli Researchers: Smartphone App May Help Parkinson’s Patients [video]

Thursday, June 25th, 2015

Many patients in the latter stage of Parkinson’s disease are at high risk of dangerous, sometimes fatal, falls. One major reason is the disabling symptom referred to as Freezing of Gait (FoG) — brief episodes of an inability to step forward that typically occurs during gait initiation or when turning while walking.

Patients who experience FoG often lose their independence, which has a direct effect on their already degenerating quality of life. In the absence of effective pharmacological therapies for FoG, technology-based solutions to alleviate the symptom and prolong the patients’ ability to live independently are desperately being sought.

CuPID is a project three years in the making and the product of an eight-member European Union-funded consortium including researchers at Tel Aviv University. It strives to provide personalized rehabilitation for patients with Parkinson’s disease who experience FoG or other gait disturbances.

CuPID is a home-based, personalized rehabilitation tool in the form of a Smartphone app that harnesses wearable sensors, audio biofeedback, and external cueing to provide intense motivational training tailored to each patient. The results are monitored remotely by medical professionals, who provide quality care while enhancing patient compliance.

The CuPID app just completed its pilot run and is being fine-tuned for more widespread use. It utilizes small sensors placed on a patient’s shoes that measure a person’s gait in “real-time.” If certain deviations from a pre-set norm emerge, an audio message alerts the patient to change his or her walking pattern immediately to avoid a dangerous situation.

Tel Aviv University Prof. Jeffrey Hausdorff said:

FoG is a leading cause of disability in patients with Parkinson’s disease. It often occurs during ‘walking transitions’ associated with turning, starting, stopping, and moving in open spaces. It can also occur when people approach narrow spaces, such as doors or elevators, and in crowded places. Recognizing such situations is a very powerful key for prevention — and this is one of the features of this program.

Prof. Hausdorff and his team at Tel Aviv Medical Center conducted a pilot study on 40 subjects: 20 patients with Parkinson’s disease who used the CuPID app and 20 patients who carried out conventional exercises and did not use the app. The results are promising and the investigators are currently exploring the possibility of a larger follow-up study to further demonstrate the app’s efficacy. Tel Aviv University Dr. Anat Mirelman, who co-directed the project, explained that FoG episodes resemble a short-circuit in the brain, rendering it unable to generate the appropriate stepping pattern, often leaving the patient in an untenable and frustrating situation. The app is designed to circumvent that difficulty. She said:

FoG reduces patients’ independence. Patients become afraid of walking by themselves and this leads to self-imposed restrictions in mobility. When their feet get stuck to the ground, their bodies lunge forward — it’s very frightening. People often end up in wheelchairs, and this is a vicious cycle, as it places more reliance on the assisted-living infrastructure.

“The program now integrates the expertise of a patient’s physical therapist, who establishes what is considered a patient’s ‘normal’ or ‘strong’ walking pattern,” said Prof. Hausdorff. “It’s unobtrusive and has the potential to reduce dependence on Parkinson’s medication that has detrimental side effects. How much or how often the app is used depends on how advanced the disease is, but since the system is so small and non-invasive, it can be used just about anywhere.”

Israeli Scientists Start to Bring Star Trek Tricorder to Life

Thursday, April 2nd, 2015

Israeli scientists at Tel Aviv University’s School of Electrical Engineering are in the process of bringing the iconic Star Trek “tricorder” to life.

The essential multi-functional tool used on board the Starship Enterprise as it explored new worlds on its five-year mission in space was used to sense, compute and record data in a non-threatening manner.

So too is a new optical component and imaging processing software developed by Professor David Mendlovic and his doctoral student Ariel Raz.

Mendlovic states the obvious: “A long list stands to gain from this new technology. We predict hyperspectral imaging will play a major role in consumer electronics, the automotive industry, biotechnology and homeland security.”

The two men came together with a team of researchers at the Unispectral Technologies firm and patented an optical component based on existing microelecctromechanical (MEMS) technology that can be used in mass production and is compatible with standard smartphone cameras. The combination of the optical component and newly designed software, however, go further than the current smartphone cameras by offering superior imaging performance and hyperspectral imaging capabilities, Mendlovic said.

“The optical element acts as a tunable filter and the software – an image fusion library – would support this new component and extract all the relevant information from the image,” he said. It works both in video and still photography,” he added.

Ramot is the tech transfer company for Tel Aviv University, and acted to consolidate key intellectual properties. It financed the engineering team to go ahead with the research and development phase of the project, as well as the business development.

Funders for Unispectral include Momentum Fund, backed by Tata Group Ltd and Temasek, based in Singapore. SanDisk also has an interest in the project.

Unispectral is already moving forward to advance discussions with smartphone makers, automotive companies and wearable device manufacturers.

The future is near; closer than one might realize.

Israeli Start-Up May Charge Your Smartphone in 30 Seconds (Video)

Tuesday, April 8th, 2014

An Israeli startup company called StoreDot has unveiled a prototype charger that can re-energize a phone battery in 30 seconds.

The new technology was based on research for Alzheimer’s disease at the nanotechnology department of Tel Aviv University, but the prototype still needs to be developed into a smaller batter to be of commercial use. The amino acids identified in the research are used for the new charger.

The StoreDot is optimistic it will succeed and projects that the new charger will be on the market by the end of 2016.

One of the rumored investors who have plunked down more than $6 million so far is Samsung.

“We are about one year from a functional prototype that will be inside the device,” StoreDot’s CEO and founder Dr. Doron Myersdorf told TechCrunch. “Right now we show a battery that extends beyond the form factor of the smartphone. So in one year we’ll have reached the size, and in two years we’ll reach the required energy density for the entire day.

“So we are talking about three years for a commercial ready device. So I assume it will be three years before you can actually purchase it on the market.

“We’ve demonstrated an iPhone display that the active material which emits light is a bio-organic material that is created by our compounds. This will be the first ever bio-organic display. We already demonstrated all the colors… we can bring the entire RGB spectrum for the display so now it’s all a matter of being able to reach the lifetime and the efficiency similar to cadmium.”

StoreDot needs approximately an additional $20 million to further develop the prototype and set up a manufacturing facility.

Tel Aviv U. Cancels Talk by Former Arab Prisoner for Land Day

Monday, April 7th, 2014

Tel Aviv University has cancelled the appearance at a campus event of a former Arab prisoner jailed by Israel for his activities on behalf of the terrorist Hezbollah organization.

Mohammed Kana’ane, an Arab-Israeli who spent four-and-a-half years in prison, was invited to speak Monday by the left-wing Hadash and Balad student groups at a conference for Land Day, which marks the deaths of six Galilee Arabs in 1976 during riots over a government decision to expropriate land for what it called security purposes.

Land Day took place on March 30.

“In light of concern for public order in the Land Day events scheduled to be held tomorrow, and since the request to approve Kana’neh’s participation was only received recently, leaving no time for preparations, the University does not approve his participation in the event,” the university said in a statement released late Sunday. The statement said that other Land Day events would go forward as planned.

A Sunday protest on campus by Jewish student groups called for the speech to be canceled.

The university last week had issued a statement saying it would allow the event to go forward in an effort to respect students’ right to freedom of speech, which it apparently thought includes screaming “Fire!” in a crowded theater.

JTA contributed most of the material for this report.
