NATIONAL: SCIENCE & TECHNOLOGY: 4 IISc Researchers get INSA Young Scientist Awards

The award by INSA is given every three years to scientists for the best research paper published in a reputed journal.

Four faculty members of the Indian Institute of Science (IISc) have been selected for the Indian National Science Academy (INSA) Medal for Young Scientists. Dr Srimonta Gayen, Dr Subhojoy Gupta, Dr Mohit Kumar Jolly and Dr Venkatesh Rajendran are among the 42 scientists selected from across India for the medal. The INSA Medal for Young Scientists is awarded annually by INSA to scientists under the age of 40 for their contributions towards Science and Technology. Dr Gayen is an assistant professor at the Molecular Reproduction, Development and Genetics (MRDG) Department.

INSA stated that his work could help in enhancing the success rates of in-vitro fertilisation (IVF) as well as provide a clinical strategy to help prevent the prevalence of gender bias against IVF-born babies. Dr Gupta, an assistant professor at the Department of Mathematics, was awarded for his work on Riemann surfaces.

Dr Jolly, assistant professor at the Centre for BioSystems Science and Engineering (BSSE), is working on minimising cancer metastasis and preventing drug and therapy resistance on cancer cells. Dr Rajendran of the Department of Mathematics specialises in Kac-Moody algebras and their representations. Meanwhile, IISc also announced that Dr Karthik Sunagar, assistant professor at the Centre for Ecological Sciences (CES), was one of two recipients of the Professor Har Swarup Memorial Award.

The award by INSA is given every three years to scientists for the best research paper published in a reputed journal. Dr Sunagar published a paper on the geographical variations of venom in snakes that could render antivenom ineffective depending on the location. The paper, titled ‘Biogeographical venom variation in the Indian spectacled cobra (Naja naja) underscores the pressing need for pan-India efficacious snakebite therapy’ was published in the PLOS Neglected Tropical Diseases scientific journal.

NATIONAL: SCIENCE & TECHNOLOGY: JNCASR Scientists Develop Brain-like Computing with Industry Compatible Nitride Semiconductors

They used scandium nitride (ScN) to develop a device mimicking a synapse that controls the signal transmission as well as remembers the signal.

A team of scientists from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have used scandium nitride (ScN) and Complementary Metal-Oxide-Semiconductor (CMOS) compatibility to develop brain-like computing.

This invention can provide a new material for stable, CMOS-compatible optoelectronic synaptic functionalities at a relatively lower energy cost and also potential to be translated into an industrial product.

According to the Department of Science and Technology, the JNCASR team led by Dheemahi Rao who were working on nitride-based materials used their background for developing hardware for neuromorphic computing. They used ScN to develop a device mimicking a synapse that controls the signal transmission as well as remembers the signal.

“The JNCASR team demonstrates an artificial optoelectronic synapse with ScN thin films that can mimic synaptic functionalities like short-term memory, long-term memory, the transition from short-term to long-term memory, learning–forgetting, frequency selective optical filtering, frequency-dependent potentiation and depression, Hebbian learning, and logic-gate operations,” states the department.

Compared to the existing materials used to demonstrate optoelectronic synapse, ScN is more stable, CMOS compatible, and can be seamlessly integrated with existing Si technology. It can act as a platform for both excitatory and inhibitory functions. The industrial processing techniques of ScN are similar to the existing semiconductor fabrication infrastructure. Response to the optical stimuli also has the advantage of possible integration with photonic circuits known for higher speed and broader bandwidth than electronic circuits.

“Our work enables neuromorphic computing research with a stable, scalable, and CMOS-compatible III-nitride semiconductor that exhibits both excitatory and inhibitory synaptic functionalities. Unlike the previous works on all-electronic synapse, our work shows an optoelectronic synapse with a large bandwidth, reduced RC delays, and low power consumption,”said Dr. Bivas Saha, Assistant Professor, JNCASR.

Apart from JNCASR, researchers from the University of Sydney (Dr. Magnus Garbrecht and Dr. Asha I. K. Pillai) also participated in this study published recently in the scientific journal Advanced Electronic Materials.

KARNATAKA : World Konkani Centre announces 2 New Awards from this year

The World Konkani Centre, Shakthi Nagar, in Mangaluru has instituted two new awards from this year in the name of its chief patron. Each award carries ₹1 lakh in purse and a plaque.

It has chosen Ajit Ganapat Shenvi Kerkar for the P. Dayananda Pai Vishwa Konkani Ranga Shreshta Puraskar 2022 considering his lifetime contribution to the field of theatre and their contribution to the cause of Konkani.

Vidya Pai has been chosen for the P. Dayananda Pai Vishwa Konkani Anuvada Puraskar 2022 considering the enormity and impact of her translation work of Konkani literature in to English resulting in worldwide exposure for the Konkani literature, according to Nandagopal Shenoy, president, Konkani Bhas Ani Sanskriti Prathistan, World Konkani Centre.

The awards will be presented during the Vishwa Konkani Awards Ceremony to be held on February 9, 2023, in the presence of chief patron P. Dayananda Pai and other dignitaries, he said in a release.

The selection is based on the nominations submitted by the public and evaluation by two jury committees comprising of eminent personalities.

The jury for Ranga Shreshta Puraskar comprised of G.G. Lakshman Prabhu as the Chairman, and Muralidhar Shenoy from Kochi, John Permannur from Mangaluru and Sanjiv Verenkar from Goa as members.

The jury of Vishwa Konkani Anuvada Puraskar had Payyanur Ramesh Pai as Chairman and Gokuldas Prabhu, Kiran Budkuley and Melvyn Rodrigues as members.

Mr. Kerkar, 72, has served the Konkani theatre for the past 54 years in Goa. He still continues to be in the field of Konkani theatre by acting, directing and designing the sets for Konkani dramas. So far, he has acted in 89 productions and directed 43 production of dramas with innumerable shows across Goa and Maharashtra. He was instrumental in the success of 143 theatrical productions.

He is the only actor in Goa to have won the State-level best actor award for seven times including 4 times in a row.

Ms. Pai lives in Kolkota. She has translated 68 Konkani short stories and seven novels in to English and published them in reputed publications all across the world. A PhD thesis has been written based on her work and Konkani literature has received much needed attention in the literary world due to her work, the release said.
