Coarsening of biomimetic condensates in a self-stirring active fluid
Coarsening, the process where larger structures grow at the expense of smaller ones, is a fundamental aspect of multiphase systems. The cell cytoplasm exemplifies an out-of-equilibrium multiphase system, where phase-separated condensates nucleate and expand within an active fluid made of biopolymers and energy-dependent enzymes. In this study, we explore how condensates grow in a self-stirring active fluid by examining the coarsening of biomimetic condensates embedded in a 3D reconstituted cyto…

Accelerating Matrix Multiplication: A Performance Comparison Between Multi-Core CPU and GPU
Matrix multiplication is a foundational operation in scientific computing and machine learning, yet its computational complexity makes it a significant bottleneck for large-scale applications. The shift to parallel architectures, primarily multi-core CPUs and many-core GPUs, is the established solution, and these systems are now ubiquitous from datacenters to consumer laptops. This paper presents a direct, empirical performance analysis of matrix multiplication on a modern, consumer-grade heter…

A gravitational spin-orbit interaction in Poincaré gauge theory
We show a gravitational spin-orbit interaction that can potentially modify the space-time geometry naturally emerges in the framework of Poincaré gauge theory. For this purpose, we derive the field equations of a particular model with cubic order invariants and demonstrate the existence of analytical solutions which display an interaction between the intrinsic and extrinsic angular momentum parameters in the gravitational action, in analogy to the spin-orbit interaction arising from atomic and…

Effect of permeability heterogeneity on reactive convective dissolution
The impact of permeability heterogeneity on reactive buoyancy-driven convective dissolution is analyzed numerically in the case of a bimolecular A+B$\to$C reaction across varying Rayleigh numbers. The convective dynamics is compared in homogeneous, horizontally stratified, vertically stratified, and log-normally distributed permeability fields. Key variables, such as the total amount of product, mixing length, front position and width, reaction and scalar dissipation rates, and dissolution flux…

A Biomimetic Vertebraic Soft Robotic Tail for High-Speed, High-Force Dynamic Maneuvering
Robotic tails can enhance the stability and maneuverability of mobile robots, but current designs face a trade-off between the power of rigid systems and the safety of soft ones. Rigid tails generate large inertial effects but pose risks in unstructured environments, while soft tails lack sufficient speed and force. We present a Biomimetic Vertebraic Soft Robotic (BVSR) tail that resolves this challenge through a compliant pneumatic body reinforced by a passively jointed vertebral column inspir…

Nun gut, dann schaue ich mal nach in welchen Rust-Libs die ich nutze dies evt. verwendet wird. Schwachstellen gibt es in jeglichen Code doch je nach dem wird es behoben.

Krisen wie der beginnende Klimakollaps sind strategische Räume, die politische Akteure nutzen können. So z. B. der faschistoide Donald Trump, der jede staatliche Unterstützung als eigene Mildtätigkeit erscheinen lässt und sie damit (a) auf wohlgesinnte Gruppen fokussieren und (b) als Zeichen persönlicher Führungsstärke präsentieren kann:
"Dieses “keine Unterstützung für niemand, außer sie kommt von rechts/vom Volk/vom Führer” ist die zentrale strategische Leitplanke rechter Kollap…

Racing to Idle: Energy Efficiency of Matrix Multiplication on Heterogeneous CPU and GPU Architectures
The paradigm shift towards multi-core and heterogeneous computing, driven by the fundamental power and thermal limits of single-core processors, has established energy efficiency as a first-class design constraint in high-performance computing (HPC). Heterogeneous systems, integrating traditional multi-core CPUs with specialized accelerators like discrete (dGPU) and integrated (iGPU) graphics processing units, offer a compelling path to navigating the trade-offs between performance and power.
