Assessment of mesh orientation, Arbitrary‐Lagrangian‐Eulerian remeshing and mass scaling in 3D finite‐element modeling of thread‐forming screw connections Bewertung der Netzausrichtung, Arbitrary‐Lagrangian‐Eulerian‐Neuvernetzung und Massenskalierung bei der 3D‐Finite‐Elemente‐Modellierung von gewindefurchenden Schraubverbindungen

Materialwissenschaft und Werkstofftechnik, Volume 57, Issue 7, Page 672-686, July 2026.
An approach to quantify the mesh quality for simulations of bolted joints with formed female threads has been conducted for different meshing strategies. Depending on mesh orientation, Arbitrary‐Lagrangian‐Eulerian remeshing and mass scaling the quotient qH was evaluated.

Thinking of Melastomataceae: Revisiting Humboldt and Bonpland's Monographie des Melastomacées (1806–1823) from a historical perspective

TAXON, Volume 75, Issue 3, June 2026.
Abstract During their voyage to the Americas (1799–1804), Alexander von Humboldt and Aimé Bonpland described and collected American flora, fauna, minerals and other objects. After returning to Europe, they published several works, including Monographie des Melastomacées, initiated by Bonpland to classify this complex botanical family.

Heat Acclimation with Blood Flow Restriction Improves Cognitive‐Motor Dual‐Task Ability and Neuromuscular Fatigue

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT This study examined whether heat acclimation (HA), and HA with blood flow restriction (BFR) could attenuate cognition and neuromuscular function impairments in cognitive‐motor dual‐task (CMDT) during exercise‐heat stress. Twenty trained adults were randomly assigned to one of two HA protocols over six sessions (~8 days). Each session consisted

Fallschirmspringen, Paragliding und Wingsuit‐Fliegen: Im freien Fall

Physik in unserer Zeit, Volume 57, Issue 2, Page 74-78, March 2026.
Mit nichts als Schwerkraftantrieb vom Himmel zu fallen, führt zu den schnellsten Sportarten, aber auch zu den gefährlichsten. Zusammenfassung Fallschirmspringen wird erst seit 1951 als offizielle Sportart betrieben. Moderne Fallschirme sind sehr gut steuerbar, weshalb zum Beispiel das Zielspringen immer anspruchsvoller wird.

Depth Image Super‐Resolution Reconstruction Based on Fractal Encoding

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper proposes a depth‐image super‐resolution reconstruction algorithm based on fractal encoding, effectively reducing information loss by leveraging the resolution invariance of fractal self‐similarity transformations. ABSTRACT In response to challenges such as edge blurring and pseudo‐artefacts in the super‐resolution reconstruction of depth ...

A New Incremental Cycling Cognitive‐Motor Dual‐Task Test to Assess Simultaneous Sustained Attention and Neuromuscular Fatigue in Trained Athletes

Scandinavian Journal of Medicine &Science in Sports, Volume 35, Issue 9, September 2025.
ABSTRACT Cognitive performance during cognitive‐motor dual‐task (CMDT) varies with exercise intensity. According to the inverted‐U theory, low‐to‐moderate intensity enhances cognition, but this remains unexplored in trained individuals who may better sustain cognitive performance at high intensities due to improved prefrontal cortex (PFC) homeostasis ...
