OrderFusion: Encoding orderbook for end-to-end probabilistic intraday electricity price forecasting

Probabilistic forecasting of intraday electricity prices is essential to manage market uncertainties. However, current methods rely heavily on domain feature extraction, which breaks the end-to-end training pipeline and limits the model's ability to learn expressive representatio...

A 3D-printed interface holding chamber for rodent brain slice electrophysiology

Ex vivo rodent brain slices are used extensively in biomedical research to study neurophysiological processes such as synaptic transmission, seizures, and spreading depolarization. These experiments require holding chambers to maintain brain tissue health between preparation and...

Extended service catalogue (NFDI4Earth Milestone MS3.1.3)

NFDI4Earth cooperates with re3data to ensure that repository information remains accurate, up to date, and comprehensive, as it is one of the primary sources of repository metadata for the NFDI4Earth Service Catalogue. This is an ongoing process, and, as in previous years, this w...

Modelling dynamic blade loads on scaled tidal turbines due to wave-induced unsteady kinematics

Accurate prediction of wave-induced unsteady loads on tidal turbines is essential for reliable fatigue assessment and load mitigation design. These loads arise from the turbine rotating through a depth-varying flow field that oscillates at the wave frequency, requiring detailed m...

Tackling Challenges of Textile Recycling: Color Removalfrom Cotton Textile Waste via Sequential Reductive–OxidativeBleaching

Abstract An effective pathway for textile recycling could be the successful integration of the textile waste into a closed-loop system; however, one of the key challenges is the removal of color from textile waste. In this study, we developed a two-step reductive-oxidative treatm...

Escalating pyrethroid resistance in Anopheles funestus increases Plasmodium transmission

<title>Abstract</title> <bold>Background:</bold> The swift rise in pyrethroid resistance among malaria vectors poses a significant challenge to global malaria control. Although vector control tools have advanced, limited understanding of the vectorial capacity of highly pyrethroi...

Extending the sensitivity of heavy sterile neutrino searches with solar neutrino experiments

Abstract A sensitivity study of the search for heavy sterile neutrinos ($\nu_H$) in the MeV mass range using solar neutrino experiments is presented. $\nu_H$, with masses ranging from a few MeV up to around 15 MeV, can be produced in the Sun through $^8$B decay and subsequently d...

Genetic clusters of BMI reveal symptom-specific causal effects on depression

Abstract While BMI is phenotypically and genetically associated with depression, the extent to which BMI causes depression and the mechanisms underlying this effect remain unclear. We estimated the causal effect of BMI on depression symptoms, accounting for complexity in both the...

Revealing hidden nonlocality and preparation contextuality for an arbitrary input Bell inequality

Abstract In recent years, the activation of hidden nonlocality for a mixed entangled state, admitting a local model, has gained considerable interest. In this paper, we study the activation of hidden nonlocality and preparation contextuality for a class of mixed entangled states,...

Gravitational constant as a conserved charge in black hole thermodynamics

Recent work has demonstrated that coupling constants in a given action can be promoted to the role of conserved charges. This is achieved by introducing pairs of field variables constructed from combinations of scalar and gauge fields. This framework naturally suggests that the g...

Metal Oxide Chemical Looping Cycles for Coproduction of Hydrogen and Sulfuric Acid

ABSTRACT Hydrogen production via multi‐step thermochemical cycles may be an affordable, low‐carbon alternative to steam methane reforming or water electrolysis. Conventional thermochemical water splitting generates hydrogen while coproducing an oxidized product, oxygen, that has...

AI alignment in medical imaging: Unveiling hidden biases through counterfactual analysis

Machine learning (ML) systems for medical imaging have demonstrated remarkable diagnostic capabilities. However, their susceptibility to learning spurious correlations with sensitive attributes poses significant risks to fairness and safety. In this paper, we introduce a novel st...

Conformal blocks of Wess-Zumino-Witten model from its free-field representation

A bstract A powerful approach to the celebrated Wess-Zumino-Witten (WZW) model is provided by its free-field realization. However, explicit calculations of conformal blocks are not described in the literature in full detail. We begin this study with the simplest cases of the $$ \...

Regularity for monotone operators and applications to homogenization of p-Laplace type equations

In this manuscript, we provide local $L^q$-estimates for the gradient of solutions of a class of quasilinear equations whose principal part lacks strong monotonicity. These estimates are used to establish uniform large-scale $L^q$-estimates for the gradient of solutions of degene...

Measurement incompatibility in Bayesian multiparameter quantum estimation

We present a comprehensive and pedagogical formulation of Bayesian multiparameter quantum estimation. Within this framework, we analyse the role of measurement incompatibility and establish its quantitative effect on attainable precision. We achieve this by deriving upper bounds...
