Dimensional crossover of thermal conductance in graphene nanoribbons: A first-principles approach
, 2012 First-principles density-functional calculations are performed to investigate the thermal transport properties in graphene nanoribbons (GNRs). The dimensional crossover of thermal conductance from one to two dimensions (2D) is clearly demonstrated with ...

Light Therapy Alleviates Addiction‐Related Symptoms and Reshapes Habenula and Midbrain Pathways
Advanced Science, EarlyView.This study investigates light therapy for treating Internet Gaming Disorder (IGD). Functional MRI (fMRI) data reveal that light therapy enhances brain connectivity, particularly between the habenula and the medial orbitofrontal cortex (mOFC). These changes are associated with reduced withdrawal symptoms and addiction severity, highlighting the ...

QT dispersion in the electrocardiogram in hemodialysis and peritoneal dialysis patients
Saudi Journal of Kidney Diseases and Transplantation, 2014 To evaluate QT dispersion (QTd) in dialysis patients in an analytic cross-sectional study, three groups were enrolled: Hemodialysis (HD), peritoneal dialysis (PD) and control (30 patients in each group) to study QT parameters in 12-lead ...

On the Formation of Planetesimals via Secular Gravitational Instabilities with Turbulent Stirring
, 2011 We study the gravitational instability (GI) of small solids in a gas disk as a mechanism to form planetesimals. Dissipation from gas drag introduces secular GI, which proceeds even when standard GI criteria for a critical density or Toomre's $Q$ predict ...

Dispersive approach to hadronic light-by-light scattering [PDF]
, 2014 Based on dispersion theory, we present a formalism for a model-independent evaluation of the hadronic light-by-light contribution to the anomalous magnetic moment of the muon. In particular, we comment on the definition of the pion pole in this framework

Temperature behavior of the magnon modes of the square lattice antiferromagnet
, 1999 A spin-wave theory of short-range order in the square lattice Heisenberg antiferromagnet is formulated. With growing temperature from T=0 a gapless mode is shown to arise simultaneously with opening a gap in the conventional spin-wave mode.

d‐Wave Fermi Surface Instability in the Nematic Phase of Two Monolayer FeSe/SrTiO3
Advanced Science, EarlyView.Angle‐resolved photoemission spectroscopy reveals a d‐wave nematic order in two‐monolayer FeSe/SrTiO3, showing degenerate dxz/dyz bands at Γ but a pronounced splitting at M. This momentum‐dependent anisotropy identifies the nematicity as a d‐wave Fermi surface (Pomeranchuk) instability, highlighting 2D FeSe as a model platform to explore the interplay ...

A Remarkable Point: QT Dispersion in Trained Athletes
Haseki Tıp Bülteni, 2010 Aim: It is a common belief that QT dispersion can increase the risk of cardiac death by inducing arrhythmias and that this is a consequence of changes in the ventricular muscles due to heavy training.
