Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

The Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Prothrombotic Activation of Platelet Pannexin‐1 Channels in Antiphospholipid Syndrome

Arthritis &Rheumatology, EarlyView.
Objective ATP is released from platelets through both degranulation and pannexin‐1 (PANX1) channels. ATP then activates P2X receptors to amplify platelet activation via calcium‐dependent signaling. The objective of this study was to evaluate the role of platelet PANX1 channels in the pathophysiology of antiphospholipid syndrome (APS), an acquired ...

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

Asian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Possible therapeutic repositioning of valproic acid: From epileptic seizures to acute kidney injury

British Journal of Clinical Pharmacology, EarlyView.
Valproic acid, an anticonvulsant, may be repositioned to prevent acute kidney injury due to ischemia followed by reperfusion. It preserves renal functions, electrolyte homeostasis and active sodium transport in kidney tubules, and blocks the onset of hypertension.

Are Ecosystems the Missing Link in Circular Transitions? Insights From a Comprehensive Literature Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT Although recent literature on the circular economy (CE) has highlighted the important role of ecosystems, there is still limited understanding of the main themes that characterize circular ecosystems. This study addresses this gap by combining a comprehensive topic modeling analysis employing latent Dirichlet allocation (LDA) with a systematic
