Misconceptions associated with the origin of charge density waves

Advances in Physics: X, 2017
Charge density wave (CDW) is an important concept in condensed matter physics, germane to a number of physical phenomena. But the origin of CDW is still under debate, partly because the origin and properties of CDW are highly material-dependent.

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

Advanced Photonics Research
High‐charge beams remain a key research focus in laser plasma acceleration, driven by the demands of extreme experimental conditions in nuclear physics, laboratory astrophysics, and fusion research. A distinct acceleration mechanism is presented in which

The effect of transport apertures on relay-imaged, sharp-edged laser profiles in photoinjectors and the impact on electron beam properties

Journal of Synchrotron Radiation
In a photoinjector electron source, the initial transverse electron bunch properties are determined by the spatial properties of the laser beam on the photocathode.

Modelling the experimental electron density: only the synergy of various approaches can tackle the new challenges

IUCrJ, 2015
Electron density is a fundamental quantity that enables understanding of the chemical bonding in a molecule or in a solid and the chemical/physical property of a material.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Data supporting Coherent Phonon Disruption and Lock-In during a Photoinduced Charge-Density-Wave Phase Transition

, 2016
The top level folders are Bright field (BF) and diffraction (DP) UEM experimental image sequences. Each folder contains images in .dm format and .tif format with a .ulg File which provides sequencing information. There are a couple home-built movies as

Laplacian of charge density for binuclear complexes: Terminal vs bridging carbonyls [PDF]

, 1993
SCF wave functions have been computed for the ground state of Fe2(CO)9, Fe2(CO)6(C2H2) and Mn2(CO)10 complexes. These wave functions were the starting point for theoretical studies of the topology of the charge density of several carbonyl types.
