Numerical Study of Solid–liquid Two-phase Flows and Erosion in a Y-type Slurry Valve with Different Seat Structures [PDF]
Journal of Applied Fluid MechanicsAs a common industrial valve solution in slurry pipeline systems, Y-type slurry valves must be designed with properly shaped valve seat sealing rings to alleviate particle erosion and keep the valve operating in optimal condition.

Simulating Coxian phase‐type distributions for patient survival [PDF]
International Transactions in Operational Research, 2009 AbstractCoxian phase‐type distributions are a special type of Markov model that can be used to represent survival times in terms of phases through which an individual may progress until they eventually leave the system completely. Previous research has considered the Coxian phase‐type distribution to be ideal in representing patient survival in ...

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Performance Evaluation of Controlled Arrival Rate System through Matrix Geometric Method Using Transient Analysis [PDF]
Mehran University Research Journal of Engineering and Technology, 2013 Performance evaluation based on transient analysis has significant importance to those systems which never reached at equilibrium. In this paper, we develop and analyze the system through controlled arrival rate using internal limits.

Wavefront Aberration Sensor Based on a Multichannel Diffractive Optical Element
Sensors, 2020 We propose a new type of a wavefront aberration sensor, that is, a Zernike matched multichannel diffractive optical filter, which performs consistent filtering of phase distributions corresponding to Zernike polynomials. The sensitivity of the new sensor
