Treatment Level and Store Level Analyses of Healthcare Data

Risks, 2019
The presented research discusses general approaches to analyze and model healthcare data at the treatment level and at the store level. The paper consists of two parts: (1) a general analysis method for store-level product sales of an organization and (2)

Limiting Laws of Linear Eigenvalue Statistics for Unitary Invariant Matrix Models

, 2006
We study the variance and the Laplace transform of the probability law of linear eigenvalue statistics of unitary invariant Matrix Models of n-dimentional Hermitian matrices as n tends to infinity.

STANCE: a unified statistical model to detect cell-type-specific spatially variable genes in spatial transcriptomics

Nature Communications
One of the major challenges in spatial transcriptomics is to detect spatially variable genes (SVGs), whose expression patterns are non-random across tissue locations.

Positive Correlation between Normal Serum Gastrin Concentrations and Antral and Duodenal G Cells

Canadian Journal of Gastroenterology, 1994
It is controversial whether there is a correlation between serum gastrin concentrations and the density of G cells in the antral or duodenal mucosa. In this study, endoscopically obtained antral and duodenal biopsies were stained immunocytochemically for

Sailing the Deep Blue Sea of Decaying Burgers Turbulence

, 1999
We study Lagrangian trajectories and scalar transport statistics in decaying Burgers turbulence. We choose velocity fields, solutions of the inviscid Burgers equation, whose probability distributions are specified by Kida's statistics.

Estimation of Threshold Effect of Kenyan Shilling Exchange Rate on Rwandan Economy: A Semiparametric Model Approach

Journal of Applied Mathematics
The exchange rate is an important variable in international trade which is used as a parameter to determine a country’s international competitiveness and indicates the position of the country’s economy. A change in the exchange rate of the Kenya shilling

The Holling Type II Population Model Subjected to Rapid Random Attacks of Predator

Journal of Applied Mathematics, 2018
We present the analysis of a mathematical model of the dynamics of interacting predator and prey populations with the Holling type random trophic function under the assumption of random time interval passage between predator attacks on prey. We propose a

Intruder States and their Local Effect on Spectral Statistics

, 1997
The effect on spectral statistics and on the revival probability of intruder states in a random background is analysed numerically and with perturbative methods.

Gaussian Volterra processes with power-type kernels. Part I

Modern Stochastics: Theory and Applications, 2022
The stochastic process of the form \[ {X_{t}}={\int _{0}^{t}}{s^{\alpha }}\left({\int _{s}^{t}}{u^{\beta }}{(u-s)^{\gamma }}\hspace{0.1667em}du\right)\hspace{0.1667em}d{W_{s}}\] is considered, where W is a standard Wiener process, $\alpha >-\frac{1}{
