Correlation and localization properties of topological charge density and the pseudoscalar glueball mass in lattice Yang-Mills theory
Using ensembles generated with periodic or open boundary conditions in thetemporal direction, and using Wilson flow or HYP smearing to smoothen the gaugefields, we have studied the Topological Charge Density Correlator (TCDC) andthe Inverse Participation Ratio (IPR) for the topological charge densitydistribution in Lattice Yang-Mills theory. We have observed that at the samelattice volume and l...


Justifying the Naive Partonic Sum Rule for Proton Spin
We provide a theoretical basis for understanding the spin structure of theproton in terms of the spin and orbital angular momenta of free quarks andgluons in Feynman's parton picture. We show that each term in the Jaffe-Manoharspin sum rule can be related to the matrix element of a gauge-invariant, butframe-dependent operator through a matching formula in large-momentum effectivefield theory. W...
Deciphering the Glycosylation Code
Asparagine-linked carbohydrates profoundly impact glycoprotein folding, stability, and structure. However, the “glycosylation code” that relates these effects to protein sequence remains unsolved. We report atomically detailed replica exchange molecular dynamics simulations in explicit solvent that systematically investigate the impact of glycosylation upon peptides with the central sequon ...


Excess Enthalpy of Monoethanolamine + Ionic Liquid Mixtures: How Good are COSMO-RS Predictions?
Mixtures of ionic liquids (ILs) and molecular amines have been suggested for CO2 capture applications. The basic idea is to replace water, which volatilizes in the amine regeneration step and increases the parasitic energy load, with a nonvolatile ionic liquid solvent. To fully understand the thermodynamics of these systems, here experimental excess enthalpies for binary mixtures of monoethanol...
Effect of Monovalent Anions on Water Transmembrane Transport
Biological structures consist of lipid bilayers immersed in the aqueous phase. They can be considered as a two-phase system where the two phases are separated (connected) by the transition regions (interphases), which properties are affected by both lipid and aqueous phases. Interphase structure and dynamics might influence properties and/or functioning of the lipid bilayer core, including osmo...


Ensemble theory for slightly deformable granular matter
Given a granular system of slightly deformable particles, it is possible to obtain different static and jammed packings subjected to the same macroscopic constraints. These microstates can be compared in a mathematical space defined by the components of the force-moment tensor (i.e. the product of the equivalent stress by the volume of the Voronoi cell). In order to explain the statistical dist...
A – c test of holography versus quantum renormalization group
We show that a "constructive derivation" of the anti-de Sitter/conformal field theory (AdS/CFT) correspondence based on the quantum local renormalization group in large-N quantum field theories consistently provides the a – c holographic Weyl anomaly in d = 4 at the curvature squared order in the bulk action. The consistency of the construction further predicts the form of the metric beta fun...

Geodesic motion in a charged 2D stringy black hole spacetime
We study the time-like geodesics and geodesic deviation for a two-dimensional (2D) stringy black hole (BH) spacetime in Schwarzschild gauge. We have analyzed the properties of effective potential along with the structure of the possible orbits for test particles with different settings of BH parameters. The exactly solvable geodesic deviation equation is used to obtain corresponding deviation v...
A class of Hermitian generalized Jordan triple systems and Chern–Simons gauge theory
We find a class of Hermitian generalized Jordan triple systems (HGJTSs) and Hermitian (ϵ, δ)-Freudenthal–Kantor triple systems (HFKTSs). We apply one of the most simple HGJTSs which we find to a field theory and obtain a typical u(N) Chern–Simons gauge theory with a fundamental matter.

Inhibition of cellular proliferation and enhancement of hydrogen peroxide production in fibrosarcoma cell line by weak radio frequency magnetic fields
This study presents experimental data for the effects of weak radio frequency (RF) magnetic fields on hydrogen peroxide (H2O2) production and cellular growth rates of fibrosarcoma HT1080 cells in vitro. Cells were exposed either to 45 µT static magnetic fields (SMFs)-oriented vertical to the plane of growth or to SMFs combined with weak 5 and 10 MHz RF magnetic fields of 10 µTRMS intens...
Evaluation of electric field distribution in electromagnetic stimulation of human femoral head
Electromagnetic stimulation is a common therapy used to support bone healing in the case of avascular necrosis of the femoral head. In the present study, we investigated a bipolar induction screw system with an integrated coil. The aim was to analyse the influence of the screw parameters on the electric field distribution in the human femoral head. In addition, three kinds of design parameters ...

Sb Magnetic Resonance as a Local Probe for the Gap Formation in the Correlated Semimetal FeSb2
We report on a comparative study of the narrow-band semimetals FeSb2 and its structural homologue RuSb2 by means of 121,123Sb nuclear quadrupole (NQR) and nuclear magnetic resonance (NMR) spectroscopy. From NQR for both compounds two temperature regimes could be identified by use of 123(1/T1) measurements. Above 40 K a conventional activated behavior (with Δ/kB ≅ 400 K for FeSb2) dominat...
The refraction of shock pairs
We study shock refractions at the interface between two materials with convex equations of state involving only two shocks, which we refer to as shock pairs or shock pair systems. We present experimental and computational evidence for the existence of both regular and irregular shock pair systems in gases and develop a von Neumann type theory for regular systems that one can use to predict the ...
UV radiation effects on a DNA repair enzyme: conversion of a [4Fe–4S]2+ cluster into a [2Fe–2S]2+
Organisms are often exposed to different types of ionizing radiation that, directly or not, will promote damage to DNA molecules and/or other cellular structures. Because of that, organisms developed a wide range of response mechanisms to deal with these threats. Endonuclease III is one of the enzymes responsible to detect and repair oxidized pyrimidine base lesions. However, the effect of radi...
From conventional (neutron-proton) nuclear scissors to spin nuclear scissors
Investigations of the nuclear scissors mode in the frame of the Wigner Function Moments (WFM) method leading to the discovery of the new types of the nuclear collective motion are reviewed. It is demonstrated how the generalization of WFM method to take into account spin degrees of freedom allows one to reproduce all earlier described qualitative features of the conventional (neutron-proton) nu...
