Probing post-hoc reasoning in LLMs over multi-step pathfinding tasks

Yaying Chen · Siamak Layeghy · Mahsa Baktashmotlagh · Marius Portmann

Large language models (LLMs) are increasingly evaluated not only on the correctness of their outputs but also on the explanations they provide for their answers. To study LLM output behaviour in a controlled setting, including both final answers and post-hoc explanations, we use shortest-path routing as a testbed: it p...

Structure-preserving transfer of Grad–Shafranov equilibria to magnetohydrodynamic solvers

Rushan Zhang · Golo Wimmer · Qi Tang

Magnetohydrodynamic (MHD) solvers used to study dynamic plasmas for magnetic confinement fusion typically rely on initial conditions that describe force balance, which are provided by an equilibrium solver based on the Grad-Shafranov (GS) equation. Transferring such equilibria from the GS discretization to the MHD disc...

Expression, purification, crystallization and structure solution of glyceraldehyde-3-phosphate dehydrogenase from the babesiosis infective agent Babesia bovis

Bruna, Ukrainski · Emelly B, Galvão · Marcio, Silva · Jorge, Iulek

Babesia bovis is a species of apicomplexan hemoparasitic protozoa that can be transmitted by ticks, causing a global cattle disease. As it depends mainly on the glycolytic pathway for energy production and life cycle maintenance, glycolytic enzymes are possible targets for drug development against Babesia. Glyceraldehy...

On-Demand Functionalized Nanomaterials for Applications in Biomedicine: Antiviral Cu(I)-Complexes Conjugated with Gold Nanorods. Investigati

Simone AMATORI · Ludovica BINELLI · Jacopo ORSILLI

Gold rod-shaped nanoparticles (AuNRs) thanks to their anisotropic shape display a peculiar optical behaviour, consisting in two plasmon bands: a transverse plasmon band corresponding to an electron oscillation along the short axis of the rod, at around 510–550 nm, and a longitudinal plasmon band, in the range 600–1200...

How to train your gel? Training and overaging in colloidal gels using rheo-SAXS-XPCS measurements

William CHEVREMONT · Lorenzo METILLI · JULIEN BAULAND · Emmeline BRASSAC · y 4 más

Amorphous materials such as polymeric, colloidal or spin glasses are thermodynamically out of equilibrium materials. Such materials undergo aging, a microstructural evolution under quiescent conditions, wherein their free energy decreases with time [1]. Aging can be altered by training the material with a succession of...

Evolution of alcohol oxidase for improved methanol bioconversion and formaldehyde tolerance

Ding, Xu-Wei · Sun, Ya-Juan · Hu, Xiao-Yu · Yang, Jun-Yi · y 3 más

Methanol oxidation by alcohol oxidases (AOXs) is a key bottleneck in one-carbon (C1) bioconversion due to limited catalytic efficiency and poor formaldehyde tolerance. Here, we report the directed evolution of an alcohol oxidase from Gloeophyllum trabeum, yielding an optimized variant, GtAOXM3. The engineered enzyme ex...

Perdiendo sabores: factores socioculturales detrás del declive de la cocina tradicional en Santa María, Perú

Patricia Elena Ramos La Rosa · Carlos Bernardino Ruiz Huaraz

Traditional cuisine constitutes a central component of intangible cultural heritage and territorial identity; however, in many local contexts it is undergoing a progressive process of decline associated with sociocultural and territorial transformations. This study aims to determine the sociocultural factors influencin...

Southern Germany cryo-EM BAG: Structural analysis of protein machineries using single particle cryo-EM

Hok Sau KWONG · Carola HUNTE · HERMANN SCHINDELIN · Regina WIRSING

Single particle electron cryomicroscopy (Cryo-EM) has become the method of choice for determining the structure of large macromolecular complexes and membrane proteins, which were previously particularly difficult to study using X-ray crystallography. In recent years, this method has also proved useful for the structur...

Modeling air source heat pumps under severe frosting conditions and evaluating performance during demand response events

Markus, J.J. · Papadimitriou, C. · Havinga, L.C. · Kok, J.K.A.H.P.J.

Managing the electric demand of heat pumps on the coldest days is an important aspect of congested low voltage grids. Specifically, severe frosting of the evaporator deteriorates system performance. Contemporary models are limited in representing severe frosting conditions. To understand the potential impacts of these...
