Entanglement Generation of Nearly-Random Operators
, 2005 We study the entanglement generation of operators whose statistical properties approach those of random matrices but are restricted in some way. These include interpolating ensemble matrices, where the interval of the independent random parameters are ...

Rapid review and meta-analysis of serial intervals for SARS-CoV-2 Delta and Omicron variants
BMC Infectious Diseases, 2023 Background The serial interval is the period of time between symptom onset in the primary case and symptom onset in the secondary case. Understanding the serial interval is important for determining transmission dynamics of infectious diseases like COVID-

Manifestation of superfluidity in an evolving Bose-condensed gas
, 2000 We study the generation of excitations due to an ''impurity''(static perturbation) placed into an oscillating Bose-condensed gas in the time-dependent trapping field. It is shown that there are two regions for the position of the local perturbation.

On the Evolution of the Cosmic Supernova Rates [PDF]
, 1998 Ongoing searches for supernovae (SNe) at cosmological distances have recently started to provide a link between SN Ia statistics and galaxy evolution. We use recent estimates of the global history of star formation to compute the theoretical Type Ia and ...

Generalized Confidence Intervals and Fiducial Intervals for Some Epidemiological Measures [PDF]
International Journal of Environmental Research and Public Health, 2016 For binary outcome data from epidemiological studies, this article investigates the interval estimation of several measures of interest in the absence or presence of categorical covariates. When covariates are present, the logistic regression model as well as the log-binomial model are investigated. The measures considered include the common odds ratio
