Regulation &Governance, EarlyView.ABSTRACT This article theorizes about weak checks and balances (C&B) and its plausible consequences. Drawing on empirical data from over 1100 municipal officials in Mexico, the study examines how executive dominance over three key institutions—the local council, internal comptroller offices, and human resources offices—facilitates consequences ...

The theoretical basis of reservoir pressure in arteries
Experimental Physiology, EarlyView.Abstract The separation of measured arterial pressure into a reservoir pressure and an excess pressure was introduced over 20 years ago as a heuristic hypothesis. Since then it has gained some traction through epidemiological studies that show that various measures of reservoir and excess pressure are independent risk factors for cardiovascular disease.

When NCX switches sides: Experimental and computational insights into Ca2+ regulation in the heart
The Journal of Physiology, EarlyView.Abstract figure legend Due to its presence inside the dyadic cleft, Na+/Ca2+ exchanger (NCX) builds a functional unit together with L‐type calcium channels and ryanodine receptors in the dyadic cleft. NCX acts bidirectionally (forward and reverse mode) dependent on extracellular calcium ([Ca2+]o) and sodium ([Na+]o) concentrations and the membrane ...

The Journal of Physiology, EarlyView.Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

The Journal of Physiology, EarlyView.Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

On‐Chip Learning With Crossbar Arrays for Adaptive Edge Intelligence
Advanced Computing, Volume 1, Issue 1, December 2026.Memristor crossbar arrays implemented on chip combines memory, computation, and learning. They allow for adapting the neural weights using the incoming sensor data. This architecture reduces data movement leading to low‐latency, energy‐efficient intelligence in edge while being reliability‐aware co‐design across devices, circuits, and algorithms that ...
