Reformulation of DFT + U as a Pseudohybrid Hubbard Density Funcitonal for Accelerated Materials Discovery

Description: This article introduces ACBN0, a pseudohybrid Hubbard density functional that yields an improved prediction of the band structure of insulators such as transition-metal oxides, with only a negligible increase in computational cost.

Giant cross-magnetic-field steps due to binary collisions between pair particles

Description: Article explores giant cross-magnetic-field steps which occur as a result of positron-electron collisions. Within a constant magnetic field (e.g., 1 T), a collision between a positron and an electron can result in a correlated drift across the magnetic field for a continuous range of impact parameters. Within this range, drift distances orders of magnitude larger than that associated with like-charge collisions were observed by computer simulation.

Radial Expansion of a Low Energy Positron Beam Passing Through a Cold Electron Plasma within a Uniform Magnetic Field

Description: This paper from the 23rd Conference on Application of Accelerators in Research and Industry conference proceedings studies the radial expansion of a low energy positron beam passing through a cold electron plasma within a uniform magnetic field using a classical trajectory Monte Carlo simulation.

Real event detection and the treatment of congestive heart failure: an efficient technique to help cardiologists to make crucial decisions

Description: Paper discussing the treatment of congestive heart failure. Abstract: Using a method of entropic analysis of time series we establish the correlation between heartbeat long-range memory and mortality risk in patients with congestive heart failure.

Dynamical model for DNA sequences

Description: This article discusses a dynamical model for DNA sequences based on the assumption that the statistical properties of DNA paths are determined by the joint action of two processes, one deterministic with long-range correlations and the other random and δ-function correlated.

Scaling Breakdown: A Signature of Aging

Description: In this article, the authors prove that the Lévy walk is characterized by bilinear scaling. This effect mirrors the existence of a form of aging that does not require the adoption of nonstationary conditions.
