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

open access: yes, 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.

Acute triggers of myocardial infarction: A case-crossover study

open access: yesThe Egyptian Heart Journal, 2017
Acute myocardial infarction (AMI) is one of the most preventable non-communicable diseases in human. Identifying triggers of myocardial infarction (MI) and prevention ways of exposure-induced complications can reduce morbidity and mortality in people at risk.The aim of this study was to identify the emotional, environmental, physical and chemical ...

Individual Aircraft Noise Exposure Assessment for a Case-Crossover Study in Switzerland [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2020
Accurate exposure assessment is essential in environmental epidemiological studies. This is especially true for aircraft noise, which is characterized by a high spatial and temporal variation. We propose a method to assess individual aircraft noise exposure for a case-crossover study investigating the acute effects of aircraft noise on cardiovascular ...

Assessing replicability of findings across two studies of multiple features [PDF]

open access: yesBiometrika (2018), 2015
Replicability analysis aims to identify the findings that replicated across independent studies that examine the same features. We provide powerful novel replicability analysis procedures for two studies for FWER and for FDR control on the replicability claims. The suggested procedures first select the promising features from each study solely based on

Non-GABA sleep medications, suvorexant as risk factors for falls: Case-control and case-crossover study

open access: yesPLoS ONE, 2020
The aim of this study was to examine the risk of falls associated with the use of non-gamma amino butyric acid (GABA) sleep medications, suvorexant and ramelteon. This case-control and case-crossover study was performed at the Kudanzaka Hospital, Chiyoda

Light at night and cause-specific mortality risk in Mainland China: a nationwide observational study

open access: yesBMC Medicine, 2023
Background While epidemiological studies have found correlations between light at night (LAN) and health effects, none has so far investigated the impacts of LAN on population mortality yet.

Binary Outcome Copula Regression Model with Sampling Gradient Fitting [PDF]

open access: yesarXiv, 2021
Use copula to model dependency of variable extends multivariate gaussian assumption. In this paper we first empirically studied copula regression model with continous response. Both simulation study and real data study are given. Secondly we give a novel copula regression model with binary outcome, and we propose a score gradient estimation algorithms ...

Thermodynamic properties and bulk viscosity near phase transition in the Z(2) and O(4) models

open access: yes, 2009
We investigate the thermodynamic properties including equation of state, the trace anomaly, the sound velocity and the specific heat, as well as transport properties like bulk viscosity in the Z(2) and O(4) models in the Hartree approximation of Cornwall-

Stress as a Trigger for Relapses in IBD: A Case-Crossover Study

open access: yesGastroenterology Research, 2013
It is important to identify factors that influence the risk of relapses in inflammatory bowel disease. Few studies have been conducted and with limited methodology. This prospective case-crossover study, aims to examine whether perceived stress has a short-term acute effect, namely whether it acts as a trigger, on the risk of relapse in inflammatory ...
