Triggers for Preeclampsia Onset: a Case‐Crossover Study

Paediatric and Perinatal Epidemiology, 2016
AbstractBackgroundRisk factors for preeclampsia are well established, whereas, the triggers associated with timing of preeclampsia onset are not. The aim of this study was to establish whether recent infection or other triggers were associated with timing of preeclampsia onset.MethodsWe used a case‐crossover design with preeclampsia cases serving as ...

Does night-time aircraft noise trigger mortality? A case-crossover study on 24 886 cardiovascular deaths

European Heart Journal, 2020
Aims It is unclear whether night-time noise events, including from aeroplanes, could trigger a cardiovascular death. In this study, we investigate the potential acute effects of aircraft noise on mortality and the specific role of different night-time ...

Dynamical correlations in multiorbital Hubbard models: Fluctuation-exchange approximations [PDF]

, 2004
We study the two band degenerate Hubbard model using the Fluctuation Exchange approximation (FLEX) method and compare the results with Quantum Monte-Carlo calculations.

Phase structure of lattice QCD at finite temperature for 2+1 flavors of Kogut-Susskind quarks [PDF]

, 1998
We report on a study of the finite-temperature chiral transition on an $N_t=4$ lattice for 2+1 flavors of Kogut-Susskind quarks. We find the point of physical quark masses to lie in the region of crossover, in agreement with results of previous studies ...

Short term exposure to fine particulate matter and hospital admission risks and costs in the Medicare population: time stratified, case crossover study

British medical journal, 2019
Objective To assess risks and costs of hospital admission associated with short term exposure to fine particulate matter with diameter less than 2.5 µm (PM2.5) for 214 mutually exclusive disease groups.

Temporal trends of the association between ambient temperature and hospitalisations for cardiovascular diseases in Queensland, Australia from 1995 to 2016: A time-stratified case-crossover study

PLoS Medicine, 2020
Background In the context of global warming, studies have turned to assess the temporal trend of the association between temperature and health outcomes, which can be used to reflect whether human beings have adapted to the local temperature.

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.

Impact of ambient temperature on respiratory disease: a case-crossover study in Seoul

Respiratory Research
Background Respiratory diseases contribute to global morbidity and mortality, and temperature is a significant factor. We investigated the association between ambient temperature and emergency department (ED) visits for various respiratory diseases in ...

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

, 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-

Sub-Daily Exposure to Fine Particulate Matter and Ambulance Dispatches during Wildfire Seasons: A Case-Crossover Study in British Columbia, Canada

Environmental Health Perspectives, 2020
Background: Exposure to fine particulate matter (PM2.5) during wildfire seasons has been associated with adverse health outcomes. Previous studies have focused on daily exposure, but PM2.5 levels in smoke events can vary considerably within 1 d ...
