Universal Chern number statistics in random matrix fields

SciPost Physics, 2023
We investigate the probability distribution of Chern numbers (quantum Hall conductance integers) for a parametric version of the GUE random matrix ensemble, which is a model for a chaotic or disordered system.

Statistics of radiation at Josephson parametric resonance

, 2011
Motivated by recent experiments, we study theoretically the full counting statistics of radiation emitted below the threshold of parametric resonance in a Josephson junction circuit.

Parametric versus non-parametric statistics in the analysis of randomized trials with non-normally distributed data

BMC Medical Research Methodology, 2005
Background It has generally been argued that parametric statistics should not be applied to data with non-normal distributions. Empirical research has demonstrated that Mann-Whitney generally has greater power than the t-test unless data are sampled from

Highly nonclassical photon statistics in parametric down conversion

, 2006
We use photon counters to obtain the joint photon counting statistics from twin-beam non-degenerate parametric down conversion, and we demonstrate directly, and with no auxiliary assumptions, that these twin beams are ...

Practical guide to using Kendall’s τ in the context of forecasting critical transitions

Royal Society Open Science, 2022
Recent studies demonstrate that trends in indicators extracted from measured time series can indicate an approach of an impending transition. Kendall’s τ coefficient is often used to study the trend of statistics related to the critical slowing down ...

Robust Statistics [PDF]

, 2018
In lieu of an abstract, here is the entry\u27s first paragraph: Robust statistics are procedures that maintain nominal Type I error rates and statistical power in the presence of violations of the assumptions that underpin parametric inferential ...

Quantum optics of a Bose-Einstein condensate coupled to a quantized light field

, 1999
We consider the interaction between a Bose-Einstein condensate and a single-mode quantized light field in the presence of a strong far off-resonant pump laser.

Nutritional and Behavioral Intervention for Long‐Term Childhood Acute Leukemia Survivors With Metabolic Syndrome

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Metabolic syndrome (MetS) is a common complication in survivors of childhood acute lymphoblastic and myeloid leukemia (AL), and a major risk factor for premature cardiovascular disease, type‐2‐diabetes, and metabolic dysfunction‐associated steatotic liver disease (MASLD).

Penalized variable selection procedure for Cox models with semiparametric relative risk

, 2010
We study the Cox models with semiparametric relative risk, which can be partially linear with one nonparametric component, or multiple additive or nonadditive nonparametric components.
