Evolution of pairing from weak to strong coupling on a honeycomb lattice [PDF]

open access: yes, 2009
We study the evolution of the pairing from weak to strong coupling on a honeycomb lattice by Quantum Monte Carlo. We show numerical evidence of the BCS-BEC crossover as the coupling strength increases on a honeycomb lattice with small fermi surface by ...

Electronic pain diary: a randomized crossover study [PDF]

open access: yesJournal of Pain and Symptom Management, 2004
Electronic pain diaries and palm-top computers have become increasingly important in clinical research and practice. In a randomized crossover trial, 24 patients suffering from chronic cancer and non-cancer pain completed both the electronic and the paper version of a pain diary based on the Minimal Documentation System (MIDOS) for pain and symptom ...

QCD thermodynamics with two flavors of Wilson quarks at N_t=6

open access: yes, 1992
We report on a study of hadron thermodynamics with two flavors of Wilson quarks on 12^3x6 lattices. We have studied the crossover between the high and low temperature regimes for three values of the hopping parameter, kappa=0.16, 0.17, and 0.18.

Aging and Crossovers in Phase-Separating Fluid Mixtures

open access: yes, 2012
We use state-of-the-art molecular dynamics simulations to study hydrodynamic effects on aging during kinetics of phase separation in a fluid mixture. The domain growth law shows a crossover from a diffusive regime to a viscous hydrodynamic regime.

Crossover Control Study of the Effect of Personal Care Products Containing Triclosan on the Microbiome

open access: yesmSphere, 2016
Commonly prescribed antibiotics are known to alter human microbiota. We hypothesized that triclosan and triclocarban, components of many household and personal care products (HPCPs), may alter the oral and gut microbiota, with potential consequences for ...

Correlated electron transport through double quantum dots coupled to normal and superconducting leads

open access: yes, 2010
We study Andreev transport through double quantum dots connected in series normal and superconducting (SC) leads, using the numerical renormalization group.

BCS-BEC crossover at finite temperature in the broken-symmetry phase [PDF]

open access: yes, 2004
The BCS-BEC crossover is studied in a systematic way in the broken-symmetry phase between zero temperature and the critical temperature. This study bridges two regimes where quantum and thermal fluctuations are, respectively, important.

Short-term effects of ambient ozone on pediatric pneumonia hospital admissions: a multi-city case-crossover study in China

open access: yesEnvironmental Health and Preventive Medicine
Background: Children’s respiratory health demonstrates particular sensitivity to air pollution. Existing evidence investigating the association between short-term ozone (O3) exposure and childhood pneumonia remains insufficient and inconsistent ...

Does a functional prosection provide a more effective method of learning the anatomy of the forearm and hand than a 3D online anatomy resource?

open access: yesMedEdPublish, 2018
Recent changes to anatomy education across UK medical schools are thought to be contributing towards a lower proficiency in anatomical expertise amongst students. The introduction of alternative learning methods may help to overcome this. Prosections and

Correlation Differences in Heartbeat Fluctuations During Rest and Exercise

open access: yes, 2001
We study the heartbeat activity of healthy individuals at rest and during exercise. We focus on correlation properties of the intervals formed by successive peaks in the pulse wave and find significant scaling differences between rest and exercise.
