Background Development of hypocalcemia after treatment of hyperparathyroidism results in increased costs and risk of poorer outcomes. Previous studies have shown conflicting data about predictors of hypocalcemia after th...

BackgroundLeft ventricular (LV) geometric remodeling is a key pathophysiological feature in heart failure with preserved ejection fraction (HFpEF), yet its prognostic implications among patients with concomitant atrial f...

Abstract A 7‐year‐old neutered male alpaca (Vicugna pacos) was presented for evaluation of a 3‐year history of large, bilateral, firm ventral cervical masses causing esophageal and tracheal impingement. Ultrasound ...

One of the main figures of merit in laser-ablative propulsion is the specific impulse, Isp, defined as the impulse per unit weight of fuel, and it is related to the exhaust velocity, ve, by the acceleration of gravity, I...

 In the present work, the colloidal nanoparticles were prepared from a bulk metal by laser ablation technique. Copper thin films were fabricated via a simple deposition method (drop casting method). This study focuses...

Abstract Background Typical atrioventricular accessory pathways (APs) are composed of myocardial cells. They provide electrical connections between atria and ventricles separate from the normal conduction system. Accesso...

The Desert Andes contain >4500 ice masses, but only a handful are currently being monitored. We present the mass changes of the small mountain glacier Agua Negra (1 km2) and of the rest of glaciers in the Jáchal river b...

The inherent non-stationarity, weak periodicity, and abrupt transient mutations of wind turbine gearbox vibration signals present substantial challenges to traditional diagnostic frameworks. To improve diagnostic accurac...

Abstract Large-scale mining equipment operates under extreme conditions, making accurate fault prediction and remaining useful life (RUL) estimation essential for predictive maintenance strategies. This paper proposes a ...

ABSTRACT Influence maximisation (IM) aims to select a small number of nodes that are able to maximise their influence in a network and covers a wide range of applications. Despite numerous attempts to provide effective s...

Abstract Graph Neural Networks (GNNs) are powerful tools for predicting chemical shifts in Nuclear Magnetic Resonance (NMR) spectroscopy. In this paper, we improve the state-of-the-art mean absolute error (MAE) on the Il...

Abstract Background Chinese hamster ovary (CHO) cells are pivotal in biopharmaceutical production, yet balancing high recombinant protein yield with cell survival remains challenging. While previous studies have targeted...

Abstract Medical image segmentation is fundamental for delineating lesion and organ boundaries in clinical workflows. While UNet-based models remain widely used, CNN-dominant designs are limited in modeling long-range co...
