Effects of Dust Event Days on Influenza: Evidence from Arid Environments in Lanzhou

Aerosol and Air Quality Research, 2022
Airborne aerosol is believed to be an important pathway for infectious disease transmissions like COVID-19 and influenza. However, the effects of dust event days on influenza have been rarely explored, particularly in arid environments.

Nontrivial critical crossover between directed percolation models: Effect of infinitely many absorbing states

, 2007
At non-equilibrium phase transitions into absorbing (trapped) states, it is well known that the directed percolation (DP) critical scaling is shared by two classes of models with a single (S) absorbing state and with infinitely many (IM) absorbing states.

Sample size estimation for case‐crossover studies

Statistics in Medicine, 2018
Case‐crossover study designs are observational studies used to assess postmarket safety of medical products (eg, vaccines or drugs). As a case‐crossover study is self‐controlled, its advantages include better control for confounding because the design controls for any time‐invariant measured and unmeasured confounding and potentially greater ...

Superfluid density of states and pseudogap phenomenon in the BCS-BEC crossover regime of a superfluid Fermi gas

, 2010
We investigate single-particle excitations and strong-coupling effects in the BCS-BEC crossover regime of a superfluid Fermi gas. Including phase and amplitude fluctuations of the superfluid order parameter within a $T$-matrix theory, we calculate the ...

Kinetics of Surface Enrichment: A Molecular Dynamics Study [PDF]

, 2010
We use molecular dynamics (MD) to study the kinetics of surface enrichment (SE) in a stable homogeneous mixture (AB), placed in contact with a surface which preferentially attracts A. The SE profiles show a characteristic double-exponential behavior with

Singlet-triplet transition in a lateral quantum dot [PDF]

, 2003
We study transport through a lateral quantum dot in the vicinity of the singlet-triplet transition in its ground state. This transition, being sharp in an isolated dot, is broadened to a crossover by the exchange interaction of the dot electrons with the

Effects of Sucralose Supplementation on Glycemic Response, Appetite, and Gut Microbiota in Subjects with Overweight or Obesity: A Randomized Crossover Study Protocol

Methods and Protocols
Sucralose stands as the most common non-nutritive sweetener; however, its metabolic effects have sparked significant controversy over the years. We aim to examine the effects of sucralose daily intake on glycemia, subjective appetite, and gut microbiota (

Extraction bradycardia: a pilot case-crossover study [PDF]

Head & Face Medicine, 2013
Abstract Purpose Significant vasovagal reaction is one of the untoward events in the course of simple extractions. The present study then aimed to record the patients’ heart rate during the extraction procedure. Materials and methods Informed consents were obtained in ...

Crossover from the parity-conserving pair contact process with diffusion to other universality classes [PDF]

, 2009
The pair contact process with diffusion (PCPD) with modulo 2 conservation (\pcpdt) [$2A\to 4A$, $2A\to 0$] is studied in one dimension, focused on the crossover to other well established universality classes: the directed Ising (DI) and the directed ...
