Critical phenomena near the antiferromagnetic quantum critical point of Heavy-Fermions

, 2000
We present a study of the critical phenomena around the quantum critical point in heavy-fermion systems. In the framework of the S=1/2 Kondo lattice model, we introduce an extended decoupling scheme of the Kondo interaction which allows one to treat the ...

Widowhood disparities in nonaccidental mortality attributable to heat waves and ozone

Eco-Environment & Health
Emerging evidence suggests that heat waves and ozone (O3) contribute to increased mortality risks. Since widowhood is a common event that can increase individuals' susceptibility to the environment, it is of great importance and interest to elucidate the

Antipsychotic medications and stroke in schizophrenia: A case-crossover study

PLOS ONE, 2017
The association between antipsychotic use and the risk of stroke in schizophrenic patients is controversial. We sought to study the association in a nationwide cohort with schizophrenia.Using a retrospective cohort of patients with schizophrenia (N = 31,976) derived from the Taiwan National Health Insurance Research Database, 802 new-onset cases of ...

Multicritical crossovers near the dilute Bose gas quantum critical point

, 1996
Many zero temperature transitions, involving the deviation in the value of a $U(1)$ conserved charge from a quantized value, are described by the dilute Bose gas quantum critical point.

Phase diagram of polymer blends in confined geometry [PDF]

, 2000
Within self-consistent field theory we study the phase behavior of a symmetrical binary AB polymer blend confined into a thin film. The film surfaces interact with the monomers via short range potentials.

Disordered Quantum Spin Chains with Long-Range Antiferromagnetic Interactions

, 2017
We investigate the magnetic susceptibility $\chi(T)$ of quantum spin chains of $N=1280$ spins with power-law long-range antiferromagnetic coupling as a function of their spatial decay exponent $\alpha$ and cutoff length $\xi$.

Differentiating the impact of non-optimum temperature and temperature variability on cause-specific cerebrovascular mortality: An individual-level, case-crossover study in Shanghai, China

Ecotoxicology and Environmental Safety
Background: Cerebrovascular mortality exhibits seasonal variation, but the roles of temperature and temperature variability (TV) in cause-specific cerebrovascular mortality remain unclear.

Methodological Assessment of Case–Crossover Studies

مجله اپیدمیولوژی ایران, 2008
The case-crossover design was developed in the early 1990s to study the effects of transient, short-term exposures on the risk of acute events such as myocardial infarction. To estimate relative risk, the exposure frequency during a period just before outcome onset (hazard period) is compared with exposure frequency during control time(s) in that ...
