On Truncation of the Matrix-Geometric Stationary Distributions

Mathematics, 2019
In this paper, we study queueing systems with an infinite and finite number of waiting places that can be modeled by a Quasi-Birth-and-Death process. We derive the conditions under which the stationary distribution for a loss system is a truncation of ...

Diels‐Alder Click Chemistry as a Dynamic‐Covalent Crosslinking Method in Spheroid‐Encapsulating Hydrogels for Cartilage Engineering

Advanced Healthcare Materials, EarlyView.
This research shows the development of hydrogels with Diels‐Alder click chemistry for engineering cartilage‐like tissue. The hydrogels support cartilage spheroids which could be cultured for at least 28 days. Furthermore, the spheroids showed a tendency to fuse together into a more consistent construct, and produced important components needed for ...

Irreducibility and uniqueness of stationary distribution

, 2009
In this paper, we shall prove that the irreducibility in the sense of fine topology implies the uniqueness of invariant probability measures. It is also proven that this irreducibility is strictly weaker than the strong Feller property plus irreducibility in the sense of original topology, which is the usual uniqueness condition.

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

A stochastic SEIR model with Holling type II treatment and Ornstein–Uhlenbeck process

Kuwait Journal of Science
This paper investigates a stochastic SEIR epidemic model that incorporates both Holling type II treatment and an Ornstein-Uhlenbeck process (OUP). By constructing appropriate non-negative Lyapunov functions, we establish the existence and uniqueness of a
