Global Persistence Exponent in Critical Dynamics: Finite Size induced Crossover [PDF]
, 2007 We extend the definition of a global order parameter to the case of a critical system confined between two infinite parallel plates separated by a finite distance $L$.

Environmental Health and Preventive MedicineBackground: 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 ...

, 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.

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 ...

Case-crossover Studies of Therapeutics [PDF]
Epidemiology, 2013 Self-controlled analysis methods implicitly adjust for time-invariant confounding within individuals. A person's prognosis often varies over time and affects both therapy choice and subsequent health outcomes. Current approaches may not be able to fully address this within-person confounding.

Acute triggers of myocardial infarction: A case-crossover study
The 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 ...

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-

Healing of Defects in Random Antiferromagnetic Spin Chains
, 2017 We study the effects of a weakened link in random antiferromagnetic spin chains. We show that healing occurs, and that homogeneity is restored at low energy, in a way that is qualitatively similar to the fate of impurities in clean ferromagnetic spin ...

Two-dimensional boson-fermion mixtures [PDF]
, 2009 Using mean-field theory, we study the equilibrium properties of boson-fermion mixtures confined in a harmonic pancake-shaped trap at zero temperature.
