Energy piles, which integrate bearing and heat exchange functions, hold significant value in ground source heat pump applications. However, under stratified ground conditions, the heat transfer mechanism of pile-soil heat exchange is relatively complex. Most existing analytical methods are based on constant heat source models, and this simplified assumption fails to effectively reflect the impact of dynamic thermal power variations on the thermal response of energy piles. Therefore, improving th…

Bound water in saturated clay, due to its unique electrical double-layer structure, plays a critical role in controlling the macroscopic thermo-mechanical behavior of clay. This paper focuses on the mechanism of temperature-dependent variation of bound water in saturated clay. By comparing research results from different scholars, it is found that minor differences in bound water density lead to significant discrepancies in the calculated bound water content, thereby affecting the analysis of th…

Red beds primarily refer to continental clastic rocks formed during the Jurassic, Cretaceous, Paleogene, and Neogene periods, predominantly in lacustrine, fluvial-lacustrine transitional, or piedmont proluvial facies, which are exposed worldwide. For red bed slopes with interbedded sandstone and mudstone, the key disaster-inducing factor triggering landslides is the damage and deterioration of the mudstone layers. Due to the property of red bed mudstone to deteriorate upon water contact and disi…

The southwestern mountainous region features steep terrain, deeply incised valleys, and complex geological structures. Debris flows, as a primary type of geological hazard in this area, severely constrain regional economic development due to their typical characteristics of high-frequency occurrence, ultra-strong dynamic damage, and complex dynamic movement processes.

[Abstract] In the current context of increasingly fierce global cultural competition, domestic cultural products face difficulties in "breaking through" and encounter challenges such as cultural adaptation issues and cultural discounts when "going global" to attract fans. Against this backdrop, domestic cultural products represented by "Black Myth: Wukong" have broken through traditional narratives, successfully achieving "breakthrough," "global reach," and "excellence" through Chinese elements,…

Similarity is an important component of marital satisfaction among couples; however, existing research on the relationship between the two has yielded conflicting conclusions. So, in which dimensions are couples actually similar, and how does similarity affect marital satisfaction? This study recruited 638 Chinese couples as participants and adopted a Couple‑Centered Approach (CCA). Using Profile‑Centered Similarity (PCS) and Actor‑Centered Difference Score (ADS) as indicators, it integrated act…

The Sgr A lobes at the Galactic center are a pair of bubble structures perpendicular to the Galactic disk and symmetric about the Galactic center, with a height of approximately 15 pc. X-ray observations indicate that these bubbles possess sharp boundaries and were likely formed by shocks from some energetic explosive event sweeping through the gas medium near the Galactic center. Outflows generated by the activity of the central supermassive black hole represent a plausible mechanism for the fo…
