A semi-algebraic set is a subset of $\mathbb{R}^n$ defined by a finite collection of polynomial equations and inequalities. In this paper, we investigate the problem of determining whether two points in such a set belong to the same connected component. We focus on the case where the defining equations and inequalities...

The Universal Variability Language (UVL) serves as the primary standard for describing variability models in configurable software systems. SAT/#SAT technology and knowledge-compilation tools, which are commonly used for configuration checking, feature analysis, product counting, and generating uniform random samples,...
For measuring tail risk with scarce extreme events, extreme value analysis is often invoked as the statistical tool to extrapolate to the tail of a distribution. The presence of large datasets benefits tail risk analysis by providing more observations for conducting extreme value analysis. However, large datasets can b...

1T-TaS2 is a van der Waals transition metal dichalcogenide material with unique ‘Star of David’ charge density wave (CDW) states at thermal equilibrium. Numerous studies have characterized the various CDW phases in 1T-TaS2 through observables such as resistivity, optical reflectivity, and scanning tunnelling microscopy...
Bacteriophages are killers of bacteria, currently under investigation as alternative treatment against multi-resistant bacteria. Despite their growing use, little is known on their infection molecular mechanism. Our recent elucidation of siphophage T5 interaction with its bacterial protein receptor and consequent DNA e...

Photodynamic therapy (PDT) of skin cancer relies on the generation of reactive oxygen species (ROS), but experimental systems that accurately model photodynamic reactions are limited. The aim of the present in vitro study was therefore to develop and validate a model system enabling mechanistic investigation under cont...

Spiking neural networks (SNNs) promise orders-of-magnitude efficiency gains by communicating with sparse, event-driven spikes rather than dense numerical activations. However, most training pipelines either rely on surrogate-gradient approximations or require dense time-step simulations, both of which conflict with the...

We consider Inverse Synthetic Aperture Radar (ISAR) imaging for a rotating scatterer. We begin by employing a linearised scattering model for the case of a rotating scatterer with a known centre of rotation, on a horizontal target plane, being imaged by a point-like transceiver. This model is described using a scatteri...

Chemodynamic therapy (CDT) holds great promise for tumor treatment by catalyzing endogenous hydrogen peroxide (H2O2) into cytotoxic reactive oxygen species (ROS). However, its efficacy is severely compromised by glutathione (GSH)-mediated ROS scavenging and intrinsically slow reaction kinetics. To address these limitat...
