A Rare Case of Acute Esophageal Necrosis Precipitated by Klebsiella Pneumoniae

open access: yesGastro Hep Advances, 2023
Acute esophageal necrosis is a rare condition; visualization of necrosis on esophagoduodenoscopy can help establish the diagnosis. Due to variations in blood supply, there is a higher propensity for ischemic episodes to occur along the lower esophagus ...

Wright–Fisher diffusion bridges [PDF]

open access: yesTheoretical Population Biology, 2018
{\bf Abstract} The trajectory of the frequency of an allele which begins at $x$ at time $0$ and is known to have frequency $z$ at time $T$ can be modelled by the bridge process of the Wright-Fisher diffusion. Bridges when $x=z=0$ are particularly interesting because they model the trajectory of the frequency of an allele which appears at a time, then ...

Population ageing and immigration policy [PDF]

open access: yes, 2004
In its simplest interpretation, population ageing is the increase in the average or median age of a population. It is the process by which there is a redistribution of relative population shares away from the younger to the older age ...

Hybrid Scaffolds Decouple Biochemical & Biophysical Regulation of Cell Phenotype

open access: yesAdvanced Healthcare Materials, EarlyView.
Replicating tissue‐specific extracellular matrix is crucial for understanding its role in disease. This work demonstrates independent control over stiffness, composition and 3D collagen architecture using hybrid scaffolds: patterned collagen perfused with defined hydrogels.

Investigation of Fractional Calculus for Extended Wright Hypergeometric Matrix Functions

open access: yesAbstract and Applied Analysis, 2023
Throughout this paper, we will present a new extension of the Wright hypergeometric matrix function by employing the extended Pochhammer matrix symbol. First, we present the extended hypergeometric matrix function and express certain integral equations ...

The M-Wright function in time-fractional diffusion processes: a tutorial survey

open access: yes, 2010
In the present review we survey the properties of a transcendental function of the Wright type, nowadays known as M-Wright function, entering as a probability density in a relevant class of self-similar stochastic processes that we generally refer to as ...

Transparent, Sprayable Plastic Films for Luminescent Down‐Shifted‐Assisted Plant Growth

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Spreading the light: A modular approach to down‐shifting europium‐containing polyoxotitanium luminescent cages is developed, allowing their incorporation into sprayable plastic coatings on agricultural greenhouses for accelerated plant growth. Abstract The world's steadily growing population and global heating due to climate change are a threat to food
