Subjective equality of visual self-motion and walking speed in virtual environments depends on the field of view

Typical visual displays cover only a fraction of the visual field. How do such restrictions influence the perception of visual speed during self-motion? While surrounded by a panoramic screen on which an alley of terraced houses was presented, participants walked at constant spee...

The Regular n-Flake Dust in ℝ2 Is Not Minkowski Measurable

The Minkowski measurability of self-similar sets is closely linked to the lattice or non-lattice nature of the contraction ratios of the underlying iterated function system. A long-standing conjecture of Lapidus asserts that under certain conditions a self-similar fractal set is...

Magneto‐Ionic Devices With Polymer‐Based Electrolytes

ABSTRACT Magneto‐ionics is a promising technology for unconventional magnetic data storage and energy‐efficient computing. In magneto‐ionic devices, voltage‐triggered ionic processes are exploited to control magnetic properties of an electrode in an electrolyte. Liquid electrolyt...

Agreement of markerless and marker-based joint kinetics in team sport-specific change-of-direction movements

Abstract Markerless (ML) motion capture is a practical alternative to marker-based (MB) systems, yet its ability to estimate joint kinetics during team sport-specific movements remains unclear. This study evaluated the agreement between ML and MB lower extremity joint moment esti...

Mechanical Properties of Hybrid Natural Fiber–Carbon Fiber‐Reinforced Polypropylene Nonwoven Composites: Influence of Degree of Densification, Fiber Volume Fraction and Laminate Architecture

ABSTRACT Nonwoven composites based on flax fiber (NF)‐reinforced polypropylene (PP) offer a promising route toward sustainable lightweight structures but are limited by moderate mechanical performance. In this work, a hybridization concept employing carbon fiber (CF) nonwoven sur...

Solid‐Liquid Interdiffusion Bonding Enabling Heterogeneous Integration on Flexible and Shapeable Polymer Platforms

The integration of rigid microscale electronics onto soft and flexible polymer substrates remains a key challenge for flexible electronics, biointegrated systems, and body-first microrobotics, where the mechanical body, material architecture, morphology, and primary functions are...

Influence of Photonic Crystal Size and Lattice Constant on the Lasing Performance of UV-C PCSELs

Abstract Semiconductor lasers are compact, high-power coherent light sources across a broad wavelength range in the electromagnetic spectrum, including visible and infrared. Despite significant progress, they have yet to achieve the same performance for ultraviolet-C (UV-C) wavel...

Multisensory haptic feedback for augmented bodies in diminished reality

Abstract Diminished Reality (DR) refers to techniques that visually remove real objects from a user’s view and replace the resulting area with a plausible reconstruction of the background. While DR has traditionally been used primarily as an image-processing approach, our previou...

A stochastic Galerkin method for optimal Dirichlet boundary control problems with uncertain data

Abstract The paper deals with a stochastic Galerkin approximation of elliptic Dirichlet boundary control problems with random input data. The expectation of a tracking-type cost functional with deterministic constrained control is minimized. Error estimates are derived for the co...

Supporting AI Readiness Through Digital Workflows in Materials Science

Materials science produces heterogeneous data across experiments, simulations, and industrial processes that often remain bound to local formats, manual procedures, and project‐specific software. Digital workflows address this fragmentation through explicit, repeatable, and machi...

Beyond the Static Approximation: Assessing the Impact of Conformational and Kinetic Broadening on the Description of TADF Emitters

Abstract Thermally activated delayed fluorescence (TADF) is a promising route toward high-efficiency, metal-free organic light-emitting diodes (OLEDs). However, the characterization of TADF kinetics in solid-state thin films is often complicated by pronounced multiexponential pho...

Influence of pretreatment methods on electrodeposition of magnetic Fe-Co coatings on carbon fibres

Abstract Magnetically responsive carbon fibres that can be actively aligned during composite manufacturing are of interest for improving the load bearing applications of fibre-reinforced lightweight structures. This work investigates thermal and chemical pretreatment methods to r...

Magnetic reversal behavior and domain morphology in low-damping CoFeB/Ni multilayers

Perpendicularly magnetized multilayers (MLs) with low magnetic damping and highly periodic stripe domains are promising materials for energy-efficient spintronic and magnonic devices. Here, we investigate the structure, together with the static and dynamic magnetic properties of...

Trauma and suicidality in adolescents with substance use disorders

Abstract Background Substance use and traumatic experiences have been identified as risk factors for suicidal ideation and behavior in community samples. The aim of this study was to explore these associations in a clinical sample of adolescents with substance use disorder (SUD)....

Data sacrifices and the ‘third way’ toward AI: justification and critique in local conflicts over automated surveillance

Abstract Datafication has become a central concern in debates on artificial intelligence (AI). In these discussions, the European approach to AI is often portrayed as a ‘third way’ that balances public interests with innovation. This article examines parliamentary discourse on a...

Europium Doped Atomically Precise Bismuth Oxido Nanoclusters as Molecular Building Blocks for Photoluminescent Hybrid Materials

ABSTRACT Structural and optical characterization of Eu 3+ doped atomically precise bismuth oxido nanoclusters (BiO‐NCs) of about 2 nm in size is reported. The BiO‐NC [Bi 38 O 45 (NO 3 ) 24 (dmso) 28 ]:Eu ( C‐1 D :Eu ) is transformed into soluble methacrylate ( − OMc) coordinated...

Effect of substrate detachment on residual stress redistribution in DED-Arc manufactured high-strength steel components

Abstract Additive manufacturing by DED-Arc enables the production of large and complex high-strength steel components. However, the residual stress state generated during deposition can be significantly altered when the component is separated from the substrate plate as a final m...

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...
