Setpoint weighted PI-FOPD cascade controllers synthesis for unstable time-delayed processes satisfying prespecified safety margins.

ISA Trans

December 2024

Department of Electrical Engineering, Tungnan University, No. 152, Section 3, Peishen Rd., Shenkeng Dist., New Taipei 222, Taiwan. Electronic address:

This article introduces a novel setpoint weighted PI-FOPD (SWPI-FOPD) cascade controller with a prefilter. It further describes a four-stage design strategy that sequentially enhances tracking responses, reduces overshoot, and ensures robustness for unstable time-delayed (UTD) processes. The controller applies to integrating and non-integrating UTD processes of any order and does not necessitate model order reduction or delay approximation.

Computational modelling of cardiac control following myocardial infarction using an in silico patient cohort.

J Physiol

December 2024

Daniel Baugh Institute for Functional Genomics and Computational Biology, Department of Pathology and Genomic Medicine, Thomas Jefferson University, Philadelphia, PA, USA.

Loss of cardiac physiological function following myocardial infarction (MI) is accompanied by neural adaptations in the baroreflex that are compensatory in the short term, but then become associated with long-term disease progression. One marker of these adaptations is decreased baroreflex sensitivity, a strong predictor of post-MI mortality. The relative contributions of cardiac remodelling and neural adaptation in the sensory, central brainstem and peripheral ganglionic loci to baroreflex sensitivity changes remain underexplored.

LINC01094 promotes gastric cancer through dual targeting of CDKN1A by directly binding RBMS2 and HDAC1.

Biol Direct

December 2024

Department of Gastrointestinal Surgery, Affiliated Hospital of Jiangnan University, 1000 Hefeng Road, Wuxi, 214062, Jiangsu Province, China.

Background: Accumulating studies have focused on long noncoding RNAs (lncRNAs) because of their regulatory effects on multiple cancers. However, the biological functions and molecular mechanisms of lncRNAs in gastric cancer (GC) remain to be elucidated in depth.

Methods: Long intergenic nonprotein coding RNA 1094 (LINC01094), a differentially expressed lncRNA between GC tissues and adjacent normal tissues, was identified.

Objectives: Endotype-based intervention has shown promise in treatment for patients with obstructive sleep apnea, and upper airway surgery is an important therapeutic option. However, the response to surgery varies among patients with obstructive sleep apnea. This study aims to examine changes in endotypic traits following upper airway surgery and their association with surgical outcome.

Purpose: Noradrenergics and antimuscarinics have been proposed as future pharmacotherapy for obstructive sleep apnea (OSA). However, the available randomized controlled trials (RCTs) showed heterogeneous results regarding the safety and efficacy of the combined regimen in OSA. Therefore, we performed this meta-analysis from the published RCTs to clarify this conflicting evidence.
