From straw waste to circular composites: A systematic comparison of untreated fillers in PBS, PBAT and their blends through performance, morphology and sustainability assessment

In this study, wheat straw (WS) and rice straw (RS) were added up to 30 wt% in maleic anhydride grafted polybutylene succinate (PBS) and poly(butylene adipate-co-terephthalate) (PBAT) using a co-rotating twin-screw extruder. Injection molded samples were analyzed using tensile, f...

Extruded Tunnel Lining Regeneration Project (ETLR): experimental campaign on real scale SFRC tunnel mock-ups

Background Automation in the construction industry is gaining increasing relevance, driven by the need to enhance productivity, foster innovation, and meet evolving societal demands. Slip-forming with extrudable steel fibre-reinforced concrete (SFRC) offers an innovative framewor...

Metrological Characterisation of Movella DOT Wearable Sensors for Measuring Induced and Transmitted Vibrations

The research focuses on the dynamic calibration of off-the-shelf inertial measurement unit (IMU) triaxial accelerometers, sensors generally used for kinematic analyses in sport and biomedical engineering. The assessment of Xsens Movella DOT sensors’ performance, reliability, and...

The functional impact of myofiber macroscopic organization and disarray in computational models of the murine heart

A major challenge in computational models of cardiac electromechanics is the reconstruction of myocardial fiber architecture, as direct in vivo measurements of fiber orientation are not feasible. Consequently, rule-based methods are commonly adopted as surrogates, relying on empi...

Barrier-Function-Constrained Residual RL-Based Current Control for LCL-Filtered NPC Inverters under Weak-Grid Operation

As renewable energy penetration continues to grow, grid-connected inverters are increasingly required to operate reliably under weak-grid conditions, where low short-circuit ratios, changing grid impedances, and rapid disturbances reveal the limitations of conventional fixed-gain...

For Good or Ill? A Conceptual Analysis of the Notion of Dual-use Technology

Abstract The idea that the outcomes of scientific research – even when pursued with entirely positive intentions – can be misused to cause large-scale harm is not new. More recent, however, is the tendency to use the expression dual-use research or technology to describe this phe...

Meta-learning based on Hypernetworks for State of Health prediction of lithium-ion batteries under data scarcity

Accurate prediction of the State of Health (SOH) of lithium-ion batteries is crucial for ensuring their safe and reliable operation. However, existing data-driven methods rely on large amounts of data for training, resulting in limited generalization ability under data-scarce con...

Engineered Metal-Organic Frameworks Preserve Mitochondrial Bioenergetics at Micromolar Concentrations

Abstract Metal-Organic Frameworks (MOFs) are emerging as versatile materials for bio-interfaces due to their structural tunability and ability to integrate with biological systems. Among them, the Zeolitic Imidazolate Framework ZIF-8 is widely investigated as a carrier for the de...

On a semilinear heat equation on infinite graphs II: Blow-up for arbitrary initial data and global existence

This paper is the second part of the study initiated in [1] and is devoted to finite-time blow-up and global existence for a semilinear heat equation on infinite weighted graphs. We first establish basic results on mild and classical solutions (which, to the best of our knowledge...

FOXC1 and its lncRNA FOXCUT link DNA methylation to a chondrocyte phenotype dysfunction

Abstract Objective With current osteoarthritis (OA) therapies limited to symptom management, understanding molecular drivers of disease progression is critical. As epigenetic mechanisms increasingly appear central to OA pathogenesis, this study aimed to identify epigenetically dy...

A Multi‐Software Approach to Assessing Photovoltaics Integration in Modern Enovoltaic Systems

ABSTRACT Land competition has intensified over the past two decades due to population growth, urbanization, and the push for renewable energy. The growing tension among food, energy, and land demands calls for integrated solutions. One of such approaches is agriphotovoltaics, whi...

Urban accessibility in historic built environments: A geomatics-based decision-support framework from mobile mapping data

Abstract Urban accessibility is a key component of inclusive and sustainable development, particularly in historic urban environments where complex spatial configurations and preservation constraints challenge standardised approaches. Traditional accessibility assessments are oft...

Long-Time Behavior of an Anisotropic Rigid Body Interacting with a Poiseuille Flow in an Unbounded 2-Dimensional Channel

Abstract. We study the long-time behavior of an elliptic rigid body which is allowed to vertically translate and rotate in a 2-dimensional unbounded channel under the action of a Poiseuille flow at large distances. The motion of the fluid is modeled by the incompressible Navier–S...

One-, Two-, Three-Step Processing of Waelz Slag via Sequential Hydro- and Pyrometallurgical Treatments for the Iron Recovery Enhancement

Waelz slag (WS) is a critical waste closely tied to the iron and zinc recycling cycles, which, thanks to its chemical composition, represents a potential secondary source of Fe. However, the presence of undesired elements (e.g., Zn, Pb, and S) poses major constraints for its dire...

How β -Ionone Ring Dynamics and Conformational Heterogeneity Control Carotenoid Photophysics

Abstract Carotenoid ultrafast photophysics has been studied for decades, but fully resolving their excited-state relaxation mechanisms remains a central, driving pursuit. Here, we investigate mini-β-carotene (m5) as a tractable model system, coupling high time-resolution transien...

Bridging criticality assessment and supply chain resilience: a structured framework for operationalizing mitigation actions

Critical raw materials underpin the energy transition, defense, and digitalization, yet criticality assessments remain diagnostic: they quantify supply risk and vulnerability without prescribing how to act. This gap is addressed through a structured review, from which 139 mitigat...

Adaptive generalization: An active perception framework for robust intelligent fault diagnosis under dynamic environments

The distribution shift problem induced by dynamic environments significantly degrades the performance of data-driven fault diagnosis systems in real-world applications. Although domain generalization techniques have been introduced to address distribution discrepancies, static ge...

Gradient descent in phase retrieval

Abstract Alternating projections, like Griffin-Lim and Fast Griffin-Lim algorithms, are among the most widely used iterative methods for phase retrieval. In this paper, we build upon the appendix of the original paper by Griffin and Lim and formulate them as gradient descent algo...

Quantifying the Spatio-Ecological Context of Urban Nature-Based Solutions Across European Cities

Nature-Based Solutions (NBS) are increasingly implemented to address urban environmental challenges, yet the surrounding spatial context in which they are embedded may influence the conditions supporting their ecological functioning. This study applied an integrated remote sensin...

Deep invertible autoencoders for dimensionality reduction of dynamical systems

Constructing reduced-order models (ROMs) capable of efficiently predicting the evolution of parameter-dependent high-dimensional dynamical systems is crucial in many applications in engineering and applied sciences. A popular class of projection-based ROMs projects the high-dimen...
