Proteomics- and Metabolomics-Based Investigation of the Effects of Astragalus membranaceus Powder on Meat Quality and Molecular Profiles of Longissimus dorsi Muscle in Ao-Hu Crossbred Rams

Astragalus membranaceus is a traditional Chinese medicinal herb commonly used as a feed additive in livestock production; however, the molecular mechanisms by which it influences meat quality in sheep remain poorly understood. In this study, 96 Ao-Hu crossbred rams were randomly...

Preparation Method of Simulated Deep Sandstone Materials Based on Dual Equivalence of Principal Components and Mechanical Properties, and Quantitative Evaluation of Simulation Effectiveness

Intact deep sandstone cores are scarce, heterogeneous with poorly repeatable, limiting systematic laboratory studies of deep-rock mechanical behavior. This study selected dense sandstone recovered from 1050 m in the Pingdingshan mining area as the prototype system for the develop...

Flow structure and mixing characteristics of a transverse jet in supersonic crossflow under varied boundary layers

Efficient fuel-air mixing within milliseconds is critical for scramjet performance, yet the flow physics of a transverse jet in supersonic crossflow remains insufficiently quantified. Planar Rayleigh/Mie scattering and stereoscopic particle-image velocimetry were applied to a Mac...

Low-Patching-Error Fiber Bragg Grating Multi-Dimensional Force Sensor

In order to avoid the difficulties caused by patching-errors in fiber Bragg grating multi-dimensional force sensors, this paper applies equal strength beam structure to a crossbeam elastic element, designs and implements an improved fiber Bragg grating multi-dimensional force sen...

Study on the Seismic Performance of Prefabricated Walls Under the Synergistic Effect of Different Connection Methods and Low-Carbon Materials

Dry-connected prefabricated composite walls have been increasingly used in steel structures owing to the development of building industrialization and the demand for rapid and efficient construction. However, the respective influences of dry-connection configuration and wall pane...

Existence of Solutions for Quasilinear Schrödinger Equations Under Non-Coercive Conditions

In this paper, we study the existence of solutions for a class of quasilinear Schrödinger equations under general potential conditions. The quasilinear term causing the functional to be ill-defined in H1(RN) is addressed via a dual approach involving a change of variables. To ove...
