An NMR view of protein dynamics in health and disease

A Sekhar, LE Kay - Annual review of biophysics, 2019 - annualreviews.org
Biological molecules are often highly dynamic, and this flexibility can be critical for function.
The large range of sampled timescales and the fact that many of the conformers that are …

Diagnosis and management of acute ischaemic stroke

R Hurford, A Sekhar, TAT Hughes, KW Muir - Practical Neurology, 2020 - pn.bmj.com
Acute ischaemic stroke is a major public health priority and will become increasingly relevant
to neurologists of the future. The cornerstone of effective stroke care continues to be timely …

Workflow based framework for life science informatics

A Tiwari, AKT Sekhar - Computational biology and chemistry, 2007 - Elsevier
Workflow technology is a generic mechanism to integrate diverse types of available
resources (databases, servers, software applications and different services) which facilitate …

Prevalence of incidental pancreatic cysts in the adult population on MR imaging

KS Lee, A Sekhar, NM Rofsky… - Official journal of the …, 2010 - journals.lww.com
OBJECTIVES: The reporting of incidental pancreatic cystic lesions on cross-sectional imaging
studies has dramatically increased over the last few years. The prevalence of incidental …

Application of discrete wavelet transform for detection of ball bearing race faults

S Prabhakar, AR Mohanty, AS Sekhar - Tribology International, 2002 - Elsevier
Bearing race faults have been detected by using discrete wavelet transform (DWT). Vibration
signals from ball bearings having single and multiple point defects on inner race, outer race …

[HTML][HTML] Visual experience and deprivation bidirectionally modify the composition and function of NMDA receptors in visual cortex

BD Philpot, AK Sekhar, HZ Shouval, MF Bear - Neuron, 2001 - cell.com
The receptive fields of visual cortical neurons are bidirectionally modified by sensory
deprivation and experience, but the synaptic basis for these changes is unknown. Here we …

Effects of coupling misalignment on vibrations of rotating machinery

AS Sekhar, BS Prabhu - Journal of Sound and vibration, 1995 - Elsevier
Improper aligning of shafts through couplings often leads to severe vibration problems in
many rotating machines. The rotor-bearing system is modelled using higher order finite …

[HTML][HTML] Optimization of single plate-serial dilution spotting (SP-SDS) with sample anchoring as an assured method for bacterial and yeast cfu enumeration and single …

P Thomas, AC Sekhar, R Upreti, MM Mujawar… - Biotechnology …, 2015 - Elsevier
We propose a simple technique for bacterial and yeast cfu estimations from diverse samples
with no prior idea of viable counts, designated as single plate-serial dilution spotting (SP-…

NMR paves the way for atomic level descriptions of sparsely populated, transiently formed biomolecular conformers

A Sekhar, LE Kay - Proceedings of the National Academy of …, 2013 - National Acad Sciences
The importance of dynamics to biomolecular function is becoming increasingly clear. A
description of the structure–function relationship must, therefore, include the role of motion, …

Fault detection in rotor bearing systems using time frequency techniques

NH Chandra, AS Sekhar - Mechanical Systems and Signal Processing, 2016 - Elsevier
Faults such as misalignment, rotor cracks and rotor to stator rub can exist collectively in rotor
bearing systems. It is an important task for rotor dynamic personnel to monitor and detect …
