Combined multi-parameter filtering and prioritization of a chemical library for cancer disease target

Mofeli Benedict Leoma · Kabelo Phuti Mokgopa · Kevin Alan Lobb · Tendamudzimu Tshiwawa

Cancer is a multifactorial disease and remains a significant problem owing to its complex nature. There is an urgent need to identify and design hybrid anticancer drugs that achieve a desired biological effect by combining two or more pharmacophores into a single molecule. Herein, we utilized MOLHYBRID program to gener...

Supercritical processing of recycled PLA into antimicrobial foams and fibers: Modelling morphology-driven thymol release for active food packaging

D. Morán · A. Rojas · E. Velásquez · G. López-Carballo · y 3 más

The widespread use of conventional plastics has caused significant environmental problems due to their persistence after disposal. Polylactic acid (PLA), which is derived from renewable sources, has attracted interest as an alternative material for food packaging. However, the management of PLA at the end of its life r...

Psyllium and pectin as supporting hydrocolloids differentially modulate the spatiotemporal delivery of phenolics and starch during digestion of apple pomace-fortified bread

Maria Franco · Ivan M. Lopez-Rodulfo · Federico Bianchi · Mario M. Martinez

Given the success of co-formulation with supportive hydrocolloids such as psyllium and high-methoxy pectin in facilitating the integration of apple pomace into bread systems, this study investigated the spatiotemporal release of phenolic compounds from apple pomace-fortified bread and how this release was affected by p...

Dualities of dihedral and generalised quaternion codes and applications to quantum codes

Miguel Sales-Cabrera · Xaro Soler-Escrivà · Víctor Sotomayor

Let $\mathbb{F}_q$ be a finite field of $q$ elements, for some prime power $q$, and let $G$ be a finite group. A (left) group code, or simply a $G$-code, is a (left) ideal of the group algebra $\mathbb{F}_q[G]$. In this paper, we provide a complete group-algebraic description for the Hermitian dual code of any $D_n$-co...

A cohomological invariant for algebras of degree 8 and exponent 2 in characteristic 2

Ahmed Laghribi · Nico Lorenz

Our aim in this paper is to extend a work of Sivatski to characteristic 2. More precisely, for $F$ a field of characteristic $2$ and a central simple algebra $A$ of exponent 2 that splits over a triquadratic extension of $F$ of separability degree at least 4, we attach a cohomological invariant $\inv(A) \in H_2^3(F) /...

Proximal dogleg opportunistic majorization for nonconvex and nonsmooth optimization

Zhou, Yiming · Dai, Wei

We consider minimizing a function consisting of a quadratic term and a proximable term which is possibly nonconvex and nonsmooth. This problem is also known as scaled proximal operator. Despite its simple form, existing methods suffer from slow convergence or high implementation complexity or both. To overcome these li...

Quasiconformal symbols and projected composition operators

Sinem Yelda Sönmez · Jari Taskinen

We study projected composition operators K_g with quasiconformal symbols g on weighted Bergman spaces on the open unit disc D. If the symbol were conformal, i.e.a Möbius transform of D, the corresponding composition operator would be automatically invertible at least in standard weighted spaces. We show that the invert...

A gradient flow for the porous medium equations with Dirichlet boundary conditions

Dongkwang Kim · Dowan Koo · Geuntaek Seo

We consider the gradient flow structure of the porous medium equations with non-negative constant Dirichlet boundary conditions. We construct weak solutions to the equations via the minimizing movement scheme by considering an entropy functional with respect to $Wb_2$ distance, which is a modified Wasserstein distance...

Ultrafast firing effects in Y-doped zirconia nanoparticles: Heating rate matters even under “Conventional” conditions
