General Variational Formulation of Axisymmetric Capillary Bridges: Modeling Contact Angle Hysteresis and Capillary Forces

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This work presents a general framework for deriving the Young–Laplace equation and the Young's equations for an axisymmetric capillary bridge between two parallel plates by minimizing the system's total energy. These Young's equations naturally emerge as boundary conditions associated with the Young–Laplace equation.

Frequency‐Domain Analysis of External Signal Propagation Through Sliding Mode Control Systems With Dynamic Actuators

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT The importance of frequency domain methods in analysis and design of sliding mode (SM) control systems is mostly associated with chattering, where the advantages of these methods over state‐space and Lyapunov's methods are quite obvious.

Diffusion and degradation effect switching closed form solitons to a nonlinear mathematical model

Alexandria Engineering Journal
This study investigates the (2+1)-dimensional Chaffee-Infante equation, an important nonlinear model in gravitation, fluid dynamics, and the Poincaré conjecture with diffusion and degradation coefficients.

Heart‐Rate Variability and Its Role in Non‐Cardiac Surgery Perioperative Care: Scoping Review

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background Heart rate variability (HRV) is a non‐invasive method of assessing autonomic function. Those with autonomic dysfunction may be at heightened risk of peri‐operative complications due to sympatho‐parasympathetic imbalance. This review summarises the clinical applications of HRV, approaches to how it is measured, and its role in ...

Scalable Computation of Topological Abstractions for Scalar Data

Computer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Oral Manifestations of Non Vascular Ehlers‐Danlos Syndrome Cross‐Sectional Study

Oral Diseases, EarlyView.
ABSTRACT Background Ehlers–Danlos syndromes are rare hereditary connective tissue disorders; however, their oral manifestations remain poorly characterized in molecularly confirmed individuals. The aim of this study was to describe the oral phenotype of patients with non‐vascular Ehlers‐Danlos syndromes compared to healthy controls.

Metric flows with neural networks

Machine Learning: Science and Technology
We develop a general theory of flows in the space of Riemannian metrics induced by neural network (NN) gradient descent. This is motivated in part by recent advances in approximating Calabi–Yau metrics with NNs and is enabled by recent advances in ...

Modelling the time‐resolved modulations of cardiac activity in rats: A study on pharmacological autonomic stimulation

The Journal of Physiology, EarlyView.
Abstract figure legend Time‐resolved estimation of cardiac rhythmicity parameters. A pipeline is shown for the estimation of the fluctuating cardiac parameters, based on the Poincaré plot. The Poincaré plot illustrates the successive changes in interbeat intervals (IBI).

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.
