Kernel logistic regression (KLR) is a powerful classification method widely applied across diverse domains. In many real-world scenarios, indefinite kernels capture more domain-specific structural information than positive definite kernels. This paper proposes a novel $L_1$-norm regularized indefinite kernel logistic r...

The biological upgrading of gasification‑derived syngas represents a promising route for the valorisation of residual biomass and wastes. Still, its industrial implementation remains limited by process instability and sensitivity to variable gas composition. This work addressed these issues by using mixed microbial cul...

Collagenolytic proteases have attracted increasing attention due to their ability to hydrolyze collagen and their relevance in biotechnological processes. In this study, a collagenolytic protease produced by Mucor subtilissimus UCP 1262 was characterized through an integrated evaluation of its biochemical properties, t...

This thesis investigates rapport development in multichannel business-to-consumer (B2C) service settings. Previous studies on rapport have adopted a unidirectional, single perspective (mostly the customer’s), although rapport is dyadic in nature and converges the behaviours of and outcomes for both customers and servic...

To mitigate acute wildfire ignition risks, utilities de-energize power lines in high-risk areas. The Optimal Power Shutoff (OPS) problem optimizes line energization statuses to manage wildfire ignition risks through de-energizations while reducing load shedding. OPS problems are computationally challenging Mixed-Intege...

We consider potential-based interactions between beams (or fibers) and shells (or membranes) using a coarse-grained approach with focus on van der Waals attraction and steric repulsion. The involved 6D integral over volumes of a beam and a shell is split into a 5D analytical pre-integration over the beam's cross sectio...

We report a comparative study of the luminescence emission spectra of a K-rich feldspar (amazonite) under different excitation modes, including photoluminescence (PL), radioluminescence (RL), thermoluminescence (TL) and optically stimulated luminescence (OSL). The results reveal a common set of UV, visible and red–NIR/...
Inconel 718 is an alloy used in critical components in the aero-engine industry and energy sector that has high performances characteristics at high temperature and load. Digital Volume Correlation (DVC) will be employed as a primary analysis tool, using carbide precipitates in the microstructure as "trackers", to comp...

In this article, we introduce a method to extend involutive nondegenerate set-theoretic solutions to the Yang--Baxter equation by means of equivariant mappings to graded modules, thus leading to the notion of a twisted extension. Furthermore, we define coprime extensions of solutions and prove that each coprime extensi...

Cellulose is a biodegradable polymer of many uses. It is soluble in some ionic liquids(IL), being environmental solvents. This implies complex interactions between chain and the two IL constituents. We observed that SAXS at large concentration is different from what expected for a usual polymer solution. Moreover, in p...
