The ability of insects to tolerate low temperatures, known as chill tolerance, contributes to their global distribution. However, the mechanisms underlying insect chill tolerance remain poorly understood. At low temperatures, insects enter chill coma, a reversible state of paralysis, owing to disrupted ion and water homeostasis.

Strongly alkaline dispersive soils pose a significant global challenge to both engineering applications and agricultural production, particularly in arid and semi-arid regions. Conventional soil modifiers used to address this issue not only present environmental and economic concerns but also fail to effectively improve soil alkalinity. This study investigates the potential application of acidic desulfurization gypsum (DG) as a soil modifier for dispersive soils, aiming to achieve high-value utilization of industrial solid waste.

An in-situ polymer-solution-processing approach enables the efficient production of uniform graphene-reinforced polylactic acid (G-PLA) nanocomposites with notable physical and biomedical properties. The approach effectively enhances the interfacial bonding between graphene and PLA by creating graphene dangling bonds and defects during exfoliation. As a result, an 182 % increase in Young's modulus and an 85 % increase in tensile strength can be achieved in G-PLA.

Emerging evidence recognizes aberrant glycosylation as the malignant characteristics of cancer cells, but little is known about glycogenes' roles in endometrial carcinoma (EC), especially the most aggressive subtype carrying TP53 mutations. Using unsupervised hierarchical clustering, an 11-glycogene cluster is identified to distinguish an EC subtype associated with frequent TP53 mutation and worse prognosis. Among them, MGAT4A (alpha-1,3-mannosyl-glycoprotein 4-β-N-acetylglucosaminyltransferase A) emerges as the most consistently overexpressed glycogene, contributing to EC aggressiveness.

Quantum entanglement is a fundamental characteristic of quantum mechanics, and understanding the robustness of entanglement across different mixed states is crucial for comprehending the entanglement properties of general quantum states. In this paper, the robustness of entanglement of Dicke-W and Greenberger-Horne-Zeilinger (GHZ) mixed states under different mixing ratios is calculated using the entanglement witness method. The robustnesses of entanglement of Dicke-W and GHZ mixed states are different when the probability ratio of Dicke to W is greater than 32 and less than 32.

  • The medulla oblongata has a complex structure with dense nerve fibers and intricate blood vessels, leading to varying effects when damaged.
  • Ischemic damage can cause symptoms like vertigo, difficulty swallowing (dysphagia), and speech problems (dysarthria), although facial paralysis is uncommon as the sole symptom.
  • The text discusses a specific case where a patient experienced medullary infarction characterized only by central facial paralysis on the same side (ipsilateral) as the injury.
