Insights into the flexibility of the domain-linking loop in actinobacterial coproheme decarboxylase through structures and molecular dynamics simulations. [PDF]

Protein Sci
Abstract Prokaryotic heme biosynthesis in Gram‐positive bacteria follows the coproporphyrin‐dependent heme biosynthesis pathway. The last step in this pathway is catalyzed by the enzyme coproheme decarboxylase, which oxidatively transforms two propionate groups into vinyl groups yielding heme b.

Two populations of LIGO-Virgo black holes [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
We analyse the LIGO-Virgo data, including the recently released GWTC-2dataset, to test a hypothesis that the data contains more than one population of black holes.

GstLAL: A software framework for gravitational wave discovery

SoftwareX, 2021
The GstLAL library, derived from Gstreamer and the LIGO Algorithm Library, supports a stream-based approach to gravitational-wave data processing. Although GstLAL was primarily designed to search for gravitational-wave signatures of merging black holes ...

Simulation tools for future interferometers [PDF]

, 2006
For the design and commissioning of the LIGO interferometer, simulation tools have been used explicitly and implicitly. The requirement of the advanced LIGO interferometer is much more demanding than the first generation interferometer.

Memory Consolidation, Brain Atrophy, and Metabolism in Amyloid Positive and Negative Amnestic Mild Cognitive Impairment [PDF]

Alzheimers Dement
Abstract Background The existing literature has established that Alzheimer's disease (AD) is typically characterized by changes in memory‐associated temporal and parietal lobe atrophy and hypometabolism. However, some individuals clinically diagnosed with AD do not have biomarkers consistent with AD pathology. In this cross‐sectional study, we aimed to
