Summary: We introduce an updated library, PaScaL_TDMA 2.0, which is capable of exploiting multi-GPU environments. The library extends its functionality to include GPU support and minimizes CPU-GPU data transfer by utilizing device-resident memory while retaining the original CPU-based capabilities. The library employs pipeline copying with shared memory for low-latency memory access and incorporates CUDA-aware MPI for efficient multi-GPU communication. Our GPU implementation demonstrated outstanding computational performance compared to the original CPU implementation while consuming much less energy.

Summary: The paper introduces an approach utilizing position control to ensure no penetration into a virtual stiff wall by approximating the nonlinear model of a 6-DOF parallel-structure haptic device with a piece-wise linear model. A simulation-based performance comparison study demonstrates that the new controller is capable of rendering higher stiffness than the previous solution.

Summary: We examine the fundamental coherence limit in a Stern-Gerlach interferometer for a nano-object with an embedded spin. This limit arises from the quantum uncertainty of the object's rotational degrees of freedom, which provides which-path information. We demonstrate that interferometry is simple in a weak magnetic field and short duration, and by precise adjustment over longer durations, a significant wave packet separation can be achieved. This paves the way for fundamental tests of quantum theory and quantum gravity. The findings and conclusions apply to interferometry experiments involving complex objects.

Summary: We propose a new, chiral description for massive higher-spin particles in four spacetime dimensions, which allows for the introduction of consistent interactions. Through the formulation of three theories, we successfully couple higher-spin matter with electrodynamics, non-Abelian gauge theory, or gravity, resulting in simple Lagrangians and Feynman rules similar to those of massive scalars. By using these Feynman rules, we derive tree-level scattering amplitudes with two higher-spin matter particles and various numbers of positive-helicity photons, gluons, or gravitons. These amplitudes reproduce the results obtained through on-shell recursion in a parity-conserving setting, demonstrating commonalities between chiral and nonchiral theories. The presented theories are currently the only examples of consistent interacting field theories with massive higher-spin fields.

Summary: To address the rendering quality issue of point symbols in maps, this paper proposes a point symbol rendering method using the idea of reinterpreted textures. The method encodes and organizes the vector properties of symbols into a texture structure with specific layout schemes, taking advantage of the fast access and continuity of textures to achieve refined rendering results. Experiments demonstrate that the proposed method achieves fast and stable performance while maintaining rendering quality.

Summary: Thermal cracking in reinforced concrete structures poses a significant durability challenge. Quantitative evaluation of thermal crack width and number of cracks remains challenging despite existing standards and numerical studies. This paper presents a robust prediction model based on a simplified approach to evaluate thermal cracks theoretically. A parametric study using a rigid-body-spring model (RBSM) determines the factors influencing thermal cracking characteristics in massive concrete members. The proposed energy-based prediction model, informed by the parametric study, accurately evaluates thermal cracks observed in an experimental setting. Additionally, the study investigates crack width distribution and establishes equations for the crack width gradient, which is crucial for assessing surface crack width and durability.

Summary: This paper explores a new approach to haptic rendering by shifting the focus to rendering interactions with no penetration, using a position controller in the joint space. It also introduces gain scheduling to improve performance and compares three controllers in a simulation setup. Additionally, an alternative way to model the dynamics of the device by linearizing a detailed simulation model is presented to make the approach adaptable to any device.
