The effect of efficiency and self-discharge parameterization on the sizing of hybrid energy storage systems

Abstract A hybrid energy storage system (HESS) is a widely investigated setup as a means to reduce losses and system dimensions by combining storage technologies with complementary characteristics. However, reported benefits are often based on case studies and do not clearly dist...

PERSPECTIVE: Cryopreservation of cell-populated bioengineered constructs - a roadmap for challenges, strategies, and translation

The advancement of cell-populated bioengineered constructs (BECs) has created an ever-increasing demand for effective cryopreservation strategies that guarantee long-term storage without compromising structural integrity or biological function. By allowing constructs to be stored...

Machine learning in directed energy deposition: A systematic literature review

Among metal additive manufacturing (AM) processes, directed energy deposition (DED) is a versatile route for fabricating, repairing, and coating large components. Advances in machine learning (ML) are reshaping DED via real-time monitoring, predictive modeling, and adaptive contr...

Towards unified AI-driven fracture mechanics: the extended deep energy method (XDEM)

Abstract Physics-Informed Neural Networks (PINNs) have recently emerged as powerful tools for solving partial differential equations (PDEs), with the Deep Energy Method (DEM) proving especially effective in fracture mechanics due to its energy-based formulation. Despite these adv...

Content and composition of inorganic X-ray amorphous materials in temperate climate soils determined by the Rietveld method

Inorganic X-ray amorphous materials (iXAMs) are reactive soil components, including nanocrystalline minerals and mineraloids, often overlooked by mineralogical analyses. We evaluated their abundance and composition in temperate climate soils (Cambisol, Podzol, Chernozem, and Stag...

The October Revolution: perceptions by contemporaries versus generational memory

Abstract This article examines the problem of constructing a Soviet myth of the October Revolution supplemented by consistent exclusion of alternative contemporaneous interpretations. Building on theories of cultural and communicative memory (Halbwachs; Assmann), the analysis inv...

Dissolved organic matter composition and mineral surface chemistry modulate organic retention and formation of mineral associated organic matter

The interaction between dissolved organic matter (DOM) and minerals governs OM stabilisation in soils. Heterogeneous composition of DOM and diverse mineral surface characteristics in soils make it challenging to determine reaction mechanisms at mineral-organic interfaces. To dete...

Synthesis and Activity‐Based Protein Profiling Identifies Aldo‐Keto Reductase 1C3 as Target Protein of Myxoglucamides

ABSTRACT Myxoglucamides, natural products recently isolated from Cystobacterineae sp., are featured by an unprecedented vinyl‐substituted α‐keto‐γ‐amino acid that is linked to a glycosylated 14‐methyl‐pentadecanoic acid. Thus, they unite elements from three biomolecular classes i...

Existence, Uniqueness, and Long-Time Asymptotic Behavior of Regular Solutions in Multidimensional Thermoelasticity

Abstract. We study a simplified nonlinear thermoelasticity model on two- and three-dimensional tori. A novel functional involving the Fisher information associated with temperature is introduced, extending the previous one-dimensional approach from the first two authors [ SIAM J....

The Moment of Delivery in Online Retailing: How Courier Types and Inoculation Messages Affect Reactions to the Last-Mile Experience

Online customers’ journeys span several touchpoints, which typically do not involve any interpersonal interactions with online retailers—except at the moment of delivery (MoD). When retailers use third-party courier services to fulfill orders, they relinquish control over this cr...

A Flow-Through Multi-Wavelength Sensor with Machine-Learning Calibration for Real-Time Monitoring of Microalgae Cultivation Processes

Acquiring real-time biological data is essential for effective control of microalgae cultivation processes, yet routine monitoring still depended on laborious offline analyses that relied on time-consuming wet-chemical techniques. This study introduces a flow-through, multi-wavel...

Multi‐Phase Heterostructured NiMoN Nanoflower as Bifunctional Separator Coatings for High‐Performance Lithium–Sulfur Batteries

ABSTRACT Lithium–sulfur (Li–S) batteries are considered promising candidates for next‐generation energy storage owing to their high theoretical energy density and the abundance of sulfur. However, the practical application of Li–S systems is limited by the polysulfide shuttle eff...
