THE EFFECT OF THE OVERBURDEN STRUCTURE AND INTERFACES CURVATURE ON AVO INVERSION OF PP-REFLECTIONS

Russian Journal of geophysical technologies, 2020
In this paper, we consider an effect of incorrect accounting of the overburden structure and interfaces curvature on results of nonlinear AVO inversion. The research is carried out on synthetic data obtained using ray method for two- and three-layer models with convex and concave interfaces. We show that neglect of the overburden heterogeneity leads to

Structure of soft and hard interbedded overburden rock under the influence of thickness ratio affects the cross fusion of pressure relief gas transportation and storage area

Meitan kexue jishu
In order to grasp the thickness ratio effect of soft and hard interbedded overburden structure on the cross–fusion of pressure relief gas transportation and storage area, the soft and hard interbedded overburden structure with different thickness ratios ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

FEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Subsidence Prediction of Overburden Strata and Surface Based on the Voussoir Beam Structure Theory [PDF]

Advances in Civil Engineering, 2018
The hard and stiff strata (key strata) bear the overburden load in the form of a voussoir beam structure (VBS) after break. The VBS affects both the surface subsidence and the stope underground pressure. Therefore, the reasonable method to predict the surface subsidence is based on the whole subsidence formulae of the VBS.

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Artificial Intelligence and Mental Well‐Being in Adult Education: Implications for Practice and Professional Responsibility

New Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Mental well‐being is central to adult learner success, yet many adult education institutions lack capacity to provide timely and accessible support. This article examines how artificial intelligence (AI) can strengthen mental health–adjacent supports in adult and continuing higher education, with attention to professional practice and ...

Disaster mechanism induced by overburden structure and control techniques for close-distance coal seam group

Meitan xuebao
Compared to single-seam mining, the close-distance coal seam group is strongly influenced by the movement of overburden structure resulting from upper seam mining.
