Carbon capture in redox trapping systems: sulfide - carbon dioxide interactions at hydrothermal pressures and temperatures

Ilya KUPENKO · Daniela D'ALESSIO · Valerio CERANTOLA · Malaspina NADIA · y 3 más

Global carbon dioxide emissions are continuously increasing leading to a global increment in temperature with potential massive consequences for our planet and society. This pilot project aims to investigate the reactions occurring at hydrothermal conditions in the CO2-sulfides systems in order to discover innovative w...

Pixel-wise assessment of industrial compost transformation by NIR hyperspectral imaging and chemometrics: an early-warning tool for process monitoring

Marta P. Rueda · Antoine Deryck · François Stevens · Juan Antonio Fernández Pierna · y 3 más

Ensuring reliable monitoring of industrial composting remains challenging due to feedstock heterogeneity and the limited representativeness of point-based spectroscopy. Here, near-infrared hyperspectral imaging (NIR-HSI) combined with multivariate modelling was applied for the first time to characterize an industrial o...

Synthetic polypeptide adjuvant-antibiotic combination eradicates polymicrobial assemblies, dormant bacteria and bacterial biofilm

Swagatam Barman · Md Waliullah Hossain · Aiswarya Chandrasseril Bansidhar · Ethan Older · y 3 más

In this work, we explore the potency of poly(D-peptide) (D-PP) in combination with diverse classes of antibiotics to address multidrug-resistant (MDR) Gram-negative superbugs, including their mature biofilms, polymicrobial assemblies, and dormant subpopulations, which are among complex challenging targets. The polypept...

On Courant-type bounds and spectral partitioning via Neumann domains on quantum graphs

Baptista, Luís · Hofmann, Matthias

We study the structure of eigenfunctions of the Laplacian on quantum graphs, with a particular focus on Morse eigenfunctions via nodal and Neumann domains. Building on Courant-type arguments, we establish upper bounds for the number of nodal points and explore conditions under which Neumann domains of eigenfunctions co...

Glucose and serum availability fine-tune neuronal metabolic adaptations and direct insulin signaling

Lotte Reinecke · Hannah Rumpel · J. Sophie Messner · Sarah Ertel · y 6 más

Cell culture systems are indispensable tools for studying cellular metabolism and signaling. However, subtle variations in nutrient composition, serum content, culture duration, and handling can influence cellular physiology. Despite widespread use, conditions commonly regarded as "standard" are rarely systematically e...

Reconstructing rational functions on finite Abelian groups with higher autocorrelations

Casper, W. Riley · Orozco, Bobby

The higher-order autocorrelations of integer-valued or rational-valued functions on finite Abelian groups appear naturally in X-ray crystallography, and have applications in computer vision systems, correlation tomography, correlation spectroscopy, and pattern recognition. In this paper, we consider the problem of reco...

DyMixOp: A neural operator designed from a complex dynamics perspective with local-global mixing for solving PDEs

Lai, Pengyu · Chen, Yixiao · Yang, Dewu · Wang, Rui · y 2 más

A primary challenge in using neural networks to approximate nonlinear dynamical systems governed by partial differential equations (PDEs) lies in recasting these systems into a tractable representation particularly when the dynamics are inherently non-linearizable or require infinite-dimensional spaces for linearizatio...

Simultaneous synthesis of resveratrol by dual-compartment metabolic engineering in Saccharomyces cerevisiae

Ruilin Shi · Aihua Deng · Xueliang Wang · Haorong Chen · y 5 más

Resveratrol, a plant-derived polyphenolic compound, is widely used in medicine, health care, and nutrition. Synthetic biologyenables the microbial synthesis of resveratrol as apromising alternative to traditional plant extraction. However, an insufficient precursor supply remains a critical bottleneck limiting the over...

Coupled Vlasov and non-Newtonian fluid dynamics: Existence and large-time behavior

Young-Pil Choi · Jinwook Jung · Aneta Wróblewska-Kamińska

We study a coupled kinetic-non-Newtonian fluid system on the periodic domain ${\mathbb T}^3$, where particles evolve by a Vlasov equation and interact with an incompressible power-law fluid through a drag force. We prove the global existence of weak solutions for all $p > \frac{8}{5}$, where $p > 1$ denotes the power-l...
