Sinhala & Tamil New Year: Health guidelines to be issued today

Friday, 02 April 2021 - 8:41
The Ministry of Health stated that health guidelines issued in view of the Sinhala and Tamil New Year will be released today (02).
A special discussion was also held in this regard and the proposals made there will be further discussed.
The Health Promotion Bureau stated that this year s New Year festivities will be subject to restrictions.
Chief Epidemiologist at the Epidemiology Unit, Dr. Sudath Samaraweera stated that test to detect COVID-19 will be carried out targetting those employed in the trade zones and economic development zones leaving Colombo during the New Year season.
Meanwhile, a discussion was held yesterday between the Health Minister and the Indian High Commissioner to Sri Lanka on the implementation of several new health development projects. ....

EPFL algorithm in world's most popular deep learning software

Artificial Intelligence technology © 2021 4X-image
PyTorch is used for countless AI applications ranging from Tesla’s Autopilot to Facebook’s translation software and its latest version, just launched, features an EPFL communication-efficient training algorithm that even helps the planet.
Deep learning is part of a broader family of machine learning methods, based on artificial neural networks, and has allowed us to develop everything from voice and image recognition tools, enhance drug discovery and toxicology, and improve financial fraud detection.
As the applications of machine learning become bigger, more complex and increasingly ubiquitous in our modern, digital age, neural networks have grown tremendously in size, consisting of trillions of connections. To train these models faster, researchers typically distribute the training effort over many computers or Graphics Processing Units yet, just like humans that collaborate to solve a task, collaborating comput ....

Stimulating Immune System to Fight Cancer

Max Planck scientists from Dortmund find immunoregulatory substances with newly developed test system
Cancer cells have evolved mechanisms to escape the body’s immune defense. Agents that prevent immune escape are attractive targets for the development of new cancer therapies. A group of scientists led by Herbert Waldmann and Slava Ziegler at the Max Planck Institute of Molecular Physiology in Dortmund has now developed a new cell-based test system to identify immunoregulatory modulators. Screening a library of over 150,000 substances revealed several potent substances with unprecedented structure.

Our immune system is very successful when it comes to warding off viruses and bacteria. It also recognizes cancer cells as potential enemies and fights them. However, cancer cells have developed strategies to evade surveillance by the immune system and to preven ....

Acoustic Graphene Plasmons Study Paves Way for Optoelectronic Applications

Korea Advanced Institute of Science and Technology
– The first images of mid-infrared optical waves compressed 1,000 times captured using a highly sensitive scattering-type scanning near-field optical microscope. –
KAIST researchers and their collaborators at home and abroad have successfully demonstrated a new methodology for direct near-field optical imaging of acoustic graphene plasmon fields. This strategy will provide a breakthrough for the practical applications of acoustic graphene plasmon platforms in next-generation, high-performance, graphene-based optoelectronic devices with enhanced light-matter interactions and lower propagation loss.
It was recently demonstrated that ‘graphene plasmons’ – collective oscillations of free electrons in graphene coupled to electromagnetic waves of light – can be used to trap and compress optical waves inside a very thin dielectric layer separating graphene from a metallic sheet. In such a configuration, graphene� ....
