We show that the boson peak originates from quasi-localized vibrations of string-like dynamical defects. Furthermore, we reveal that these dynamical defects provide a common structural origin for the three most fundamental dynamic modes of glassy systems: the boson peak, fast β relaxation and ...
The subsequent (second wave) outbreak of the pandemic across all parts of India was more destructive when compared to the first wave. To put it another way, it seems to be distinct over the previous year's spike in various aspects, all of which serve to increase concerns and worry. ...
Center for Climate Change Research, Indian Institute of Tropical Meteorology (IITM), Pune, IndiaBecause the southwest monsoon has broad economic and social impacts on life on the Indian subcontinent, there is considerable interest in predicting the onset and withdrawal dates of the monsoon. While ...

(2015) found that consumers gave domestic meat products (beef, pork, chicken, turkey, and lamb) a higher safety evaluation than meat products from other countries (Canada, Mexico, Brazil, New Zealand, Nicaragua, Russia, India, Thailand, and China). The perceived safety of meat from Canada ...
However, the name is something of a misnomer, as the system was most likely developed in India first. Does everyone use Arabic numerals? Today, Arabic numerals are considered relatively universal around the world. However, some cultures still use other number notation or other base systems....
In these extreme environments microbial and geochemical interactions are tightly interwoven, providing unique chemoclines and thermoclines, which together with the huge availability of diverse metal ions in their different oxidation states provide an excellent surrounding for the evolution of fundamental ...
Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients to build habitable worlds like Earth, but their origin and evolution on terrestrial planets remain highly debated. Here we discuss the processes that distributed th
The interactions between electrons and lattice vibrations are fundamental to materials behaviour. In the case of group IV–VI, V and related materials, these interactions are strong, and the materials exist near electronic and structural phase transitions. The prototypical example is PbTe whose incipie...
