Summary: This study investigates the feasibility of dyeing viscose rayon fabric using an anthocyanin solution extracted from H. sabdariffa L. calyces. Natural mordants, including walnut hull and alginate, were found to improve color strength and color fastness. The after-mordanting method resulted in the highest wash and light fastness.

Summary: This paper aims to provide guidance on the crashworthiness design of cutting energy-absorbing structures for subway vehicles. Through experimental and numerical methods, a new energy-absorbing tube structure is proposed and optimized to improve the crashworthiness and reliability of the cutting energy-absorption structure. Multiple failure modes were observed in the tool during impact tests, with mechanical wear occurring mainly in the middle of the cutting edge and tip failure primarily due to thermal wear. The proposed structure effectively reduces high temperatures and maintains uniform temperature distribution, resulting in smooth cutting forces. The optimal solution for the tool's steady-state temperature and mean average cutting force is determined using the Kriging surrogate model and NSGA-II algorithm as STT = 514 K and MCF = 131 kN.

Summary: The Einstein-lEther theory has gained attention as a gravitational theory breaking the Lorentz symmetry, playing a significant role in testing Lorentz-violating effects and quantum gravity construction. This study focuses on odd-parity gravitational perturbations describing a wormhole-like geometry under the Einstein-lEther theory. By simplifying the Lagrangian and constructing a set of coupled single-parameter dependent master equations, quasi-normal mode solutions are obtained and reveal consistency with general relativity, but also demonstrate a dynamical instability, ruling out these solutions.

Summary: Oxidative stress and inflammation are key processes in traumatic spinal cord injury (SCI), and effective antioxidant therapy is challenging. Researchers developed a hollow Co-SAzyme, which effectively reduced reactive oxygen and nitrogen species (RONS) and inflammation in the secondary injury of SCI. The Co-SAzyme demonstrated versatile RONS elimination capabilities and facilitated sustained release of minocycline for neuroprotection. In vitro and in vivo experiments confirmed the Co-SAzyme's ability to reduce apoptosis and pro-inflammatory cytokines, and improve functional recovery and neural repairs in an SCI-rat model.

Summary: This paper investigates the observational effects of spatial covariant gravities on the propagation of gravitational waves (GWs) and obtains the observational constraints on coupling coefficients of spatial covariant gravities from GW observations. The effects of spatial covariant gravities on the propagation equation of GWs can be divided into three classes: frequency-independent effects on GW speed and friction, a parity-violating amplitude and velocity birefringences, and a Lorentz-violating damping rate and dispersion of GWs. By comparing these effects with the observational results from LIGO/Virgo/KAGRA data, the most comprehensive constraints on spatial covariant gravities are derived.
