Seasonal variation of tropospheric bromine monoxide over the Rann of Kutch salt marsh seen from space [PDF]

Atmospheric Chemistry and Physics, 2016
The Rann of Kutch (India and Pakistan) is one of the largest salt deserts in the world. Being a so-called "seasonal salt marsh", it is regularly flooded during the Indian summer monsoon.

Hybrid OpenMP/MPI programs for solving the time-dependent Gross-Pitaevskii equation in a fully anisotropic trap

, 2016
We present hybrid OpenMP/MPI (Open Multi-Processing/Message Passing Interface) parallelized versions of earlier published C programs (D. Vudragovic et al., Comput. Phys. Commun.

Wet Ball Milling Synthesis of Iron Oxide Nanoparticles for High‐Efficiency, Controllable Magnetic Hyperthermia in Ovarian Cancer

Advanced Materials Technologies, EarlyView.
A wet ball‐milling method is presented to synthesize iron magnetic nanoparticles and evaluate their magnetic hyperthermia performance. Optimized particles (∼270 nm, Ms ∼114 emu/g) achieve ∼50°C heating under clinically safe alternating magnetic fields, while pulsed‐field operation enables controlled temperature regulation (∼30°C).

Forced expression of MSR repeat transcripts above a threshold limit breaks heterochromatin organisation

Nature Communications
Mouse heterochromatin is characterised by transcriptionally competent major satellite repeat (MSR) sequences and it has been proposed that MSR RNA contributes to the integrity of heterochromatin.

Restless bandit marginal productivity indices I: singleproject case and optimal control of a make-to-stock M/G/1 queue [PDF]

, 2004
This paper develops a framework based on convex optimization and economic ideas to formulate and solve by an index policy the problem of optimal dynamic effort allocation to a generic discrete-state restless bandit (i.e. binary-action: work/rest) project,

Cells Dynamically Adapt Their Nuclear Volumes and Proliferation Rates During Single to Multicellular Transitions

Advanced Science, EarlyView.
It is currently not well understood how cells regulate basic properties, e.g., volume and mechanics within dense multicellular environments like tumors. Here, we show that different cell types of cancer and also normal cells largely decrease their nuclear and cellular volumes in emerging cell clusters and that this is partly driven by cell cycle shifts.

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

Advanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Parallel implementation of Thomas algorithm for the 2D heat equation

Вестник КазНУ. Серия математика, механика, информатика, 2019
In this paper was considered a parallel implementation of the Thomas algorithm for the 2D heat equation. MPI was chosen as the technology for parallelization. The numerical solution of the two-dimensional heat conduction problem was solved using the two

Precise determination of αS( m Z 0 $ m_{Z^0 } $ ) from a global fit of energy-energy correlations to NNLO+NNLL predictions [PDF]

EPJ Web of Conferences, 2019
We present a determination of the strong coupling constant αS( m Z 0 $ m_{Z^0 } $ ) using a global fit of theory predictions in next-to-next-next-leading-order (NNLO) combined with resummed predictions at the next-to-next-leading-log level (

Extending a serial 3D two-phase CFD code to parallel execution over MPI by using the PETSc library for domain decomposition [PDF]

, 2014
To leverage the last two decades' transition in High-Performance Computing (HPC) towards clusters of compute nodes bound together with fast interconnects, a modern scalable CFD code must be able to efficiently distribute work amongst several nodes using ...
