L1-norm regularized indefinite kernel logistic regression

Shaoxin Wang · Hanjing Yao

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...

Reliable conversion of real syngas to volatile fatty acids (VFA) using mixed microbial cultures on Char-Based Sparger Reactor (CBSR)

Amiza Amiza · Yusuf Küçükağa · Andrea Facchin · Cristian Torri

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...

Biochemical, thermodynamic, and structural characterization of a collagenolytic protease from Mucor subtilissimus UCP 1262

Cardoso, Kethylen Barbara Barbosa · Silva, Jonatas de Carvalho · Nascimento, Thiago Pajeú · Porto, Ana Lúcia Figueiredo · y 5 más

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...

Developing Customer-Employee Rapport in Multichannel Business-to-Consumer (B2C) Service Settings

Hammad, Mohamed

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...

Machine learning guided optimal transmission switching to mitigate wildfire ignition risk

Weimin Huang · Ryan Piansky · Bistra Dilkina · Daniel K. Molzahn

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...

A computational model for short-range van der Waals interactions between beams and shells

A. Borković · M.H. Gfrerer · R.A. Sauer

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...

Luminescence emission bands of amazonite (KAlSi3O8) under different excitation modes

Roberto T.E.K. Martins · Matheus C.S. Nunes · Lily Bossin · Eduardo G. Yukihara · y 1 más

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/...

In-situ tensile microtomography of crack nucleation and meso-scale deformation mechanics in Ni-based alloy Inconel 718 (SAME AS IH-MA-461)

Daniel Jon FOSTER · Partha PAUL · Bratislav LUKIC

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...

Coprime extensions of indecomposable solutions to the Yang–Baxter equation

Dietzel, Carsten

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 in ionic liquids: getting solvent in or out.

Andrea CARRETERO · Patrick JUDEINSTEIN · Yu OGAWA · François BOUE · y 2 más

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...
