Control Barrier Function Based Quadratic Programs for Safety Critical Systems [PDF]

IEEE Transactions on Automatic Control, 2016
Safety critical systems involve the tight coupling between potentially conflicting control objectives and safety constraints. As a means of creating a formal framework for controlling systems of this form, and with a view toward automotive applications ...

Impact of Bacterial Metabolites on Gut Barrier Function and Host Immunity: A Focus on Bacterial Metabolism and Its Relevance for Intestinal Inflammation

Frontiers in Immunology, 2021
The diverse and dynamic microbial community of the human gastrointestinal tract plays a vital role in health, with gut microbiota supporting the development and function of the gut immune barrier.

Skin Barrier Function: The Interplay of Physical, Chemical, and Immunologic Properties

Cells, 2023
An intact barrier function of the skin is important in maintaining skin health. The regulation of the skin barrier depends on a multitude of molecular and immunological signaling pathways.

The tight junction protein ZO-1 is dispensable for barrier function but critical for effective mucosal repair.

Gastroenterology, 2021
BACKGROUND S AND AIMS: Increased permeability is implicated in the pathogenesis of intestinal disease. In vitro and in vivo studies have linked downregulation of the scaffolding protein ZO-1, encoded by the TJP1 gene, to increased tight junction ...

Skin Barrier Function and the Microbiome

International Journal of Molecular Sciences, 2022
Human skin is the largest organ and serves as the first line of defense against environmental factors. The human microbiota is defined as the total microbial community that coexists in the human body, while the microbiome refers to the collective genome ...

Safety-Critical Model Predictive Control with Discrete-Time Control Barrier Function [PDF]

American Control Conference, 2020
The optimal performance of robotic systems is usually achieved near the limit of state and input bounds. Model predictive control (MPC) is a prevalent strategy to handle these operational constraints, however, safety still remains an open challenge for ...

Skin Barrier Function in Psoriasis and Atopic Dermatitis: Transepidermal Water Loss and Temperature as Useful Tools to Assess Disease Severity

Journal of Clinical Medicine, 2021
Multiple diagnostic tools are used to evaluate psoriasis and atopic dermatitis (AD) severity, but most of them are based on subjective components.

An intercrypt subpopulation of goblet cells is essential for colonic mucus barrier function

Science, 2021
Goblet cell diversity An adult human has a gut surface area averaging 30 square meters that is bombarded daily by xenobiotics and microorganisms. Mucus synthesized by goblet cells supplies a protective barrier coating. Nyström et al.

Effects of Bacillus licheniformis and Bacillus subtilis on Gut Barrier Function, Proinflammatory Response, ROS Production and Pathogen Inhibition Properties in IPEC-J2—Escherichia coli/Salmonella Typhimurium Co-Culture

Microorganisms, 2022
The emergence of antimicrobial resistance raises serious concerns worldwide. Probiotics offer a promising alternative to enhance growth promotion in farm animals; however, their mode of action still needs to be elucidated.
