Cooperative formation flight of multiple aerial robotic vehicles (ARVs) is extensively adopted in emergency rescue and collaborative transport. But the time-varying complex disturbances are inevitable in the cooperative formation flight of multiple ARVs, which can affect the formation stability of multi-ARV systems. This paper investigates the robust formation control problems for multiple ARVs with time-varying disturbances.

Developing efficient adsorbent is imperative for the utilization of uranium resources in seawater. Marine microorganisms and bacteria play an important role in the process of adsorption of uranium. In this work, a completely bio-based antimicrobial aerogel (quaternary cellulose/chitosan aerogel-QCNF/CS) was prepared by cross-linking quaternary cellulose nanofibers (QCNF) and chitosan (CS) via citric acid (CA).

However, recent studies highlighted NF's effect on the efficacy of various electrocatalytic reactions, primarily due to the presence of electroactive chemical species at its interface. In contrast, numerous reports suggested that NF has a negligible impact on overall electrocatalytic activity.

The Hakanson index, heavy metal risk assessment standard, and secondary phase to primary ratio methods were employed to evaluate the ecological hazard of soil in the research area, while the human health risk model was utilized to evaluate the health of inhabitants. The findings indicated that:① The amount of heavy metals Zn, Cr, Cu, Ni, Pb, and Cd in the topsoil (0~20 cm) of protected vegetable land in the study region decreased successively, and the content of heavy metals in the topsoil increased with the extension of planting years, of which Cd, Zn, and Cu increased most obviously, with maximum increases of 219%, 189%, and 134%, respectively.

Methods: Data for this cross-sectional study were obtained from NHANES 1999-2004. PIR was the exposure variable, and severe headache/migraine was the dependent variable.
Soybean plant architecture has a significant impact on yield potential, but the genetic underpinnings of key architectural traits remain elusive. The primary objective of this study was to explore the genetic foundations underlying main stem node number (MSN) in soybeans. Recombinant inbred lines (RILs) contained a 234 individual derived from crosses between two cultivars Zhonghuang35 (ZH35) and Jindou21 (JD21) was evaluated for seed hardness across 3 years (2013, 2014, and 2015 in Gansu).

Early weaning strategies may disrupt SIgA levels in piglet intestines, causing a decline in immune response and early weaning stress. However, the specific microbial mechanisms modulating SIgA in early-weaned piglets are not well understood.

However, the mechanisms by which YFSJF affects lung cancer biology, particularly the immune microenvironment and metabolic processes, remain poorly understood.
Purpose: This study aims to explore how YFSJF modulates the immune microenvironment and metabolism in lung cancer, specifically its unique role in inhibiting immune evasion by targeting the TGR5/STAT3/PD-L1 pathway, which has not previously been reported.
Background: Neoadjuvant immunochemotherapy (nICT) has emerged as a popular treatment approach for advanced gastric cancer (AGC) in clinical practice worldwide. However, the response of AGC patients to nICT displays significant heterogeneity, and no existing radiomic model utilizes baseline computed tomography to predict treatment outcomes.
Aim: To establish a radiomic model to predict the response of AGC patients to nICT.
Background: This study investigated the expression and role of Synaptosome associated protein 25 (SNAP25) in high-grade neuroendocrine carcinoma (HGNEC).
Methods: We used differentially expressed analysis and weighted gene co-expression network analysis (WGCNA) to identify key genes and modules in HGNEC. KEGG and GO analyses helped understand these genes' roles, and ROC curves assessed their diagnostic value.
Rationale And Objective: To investigate the MR characteristics of phlegmonous stage and abscess stage primary spinal epidural abscess.
Materials And Methods: This study retrospectively analyzed the clinical and imaging characteristics of 27 cases of pathologically confirmed primary spinal epidural abscess. Predisposing conditions of all patients were collected.
All-solid-state batteries (ASSBs) have gained significant attention in the field of energy storage owing to their enhanced safety features based on the nonflammable solid-state electrolyte (SSE). To achieve high energy density, lithium metal is commonly considered the best choice as an anode material. However, the compatibility issues at the interface between polymer electrolytes and lithium metal pose significant challenges to their practical implementation.

Stearoyl-CoA Desaturase 1 (SCD1) is a key enzyme in fatty acid synthesis, highly expressed in numerous tumors, promoting tumor growth and metastasis, making it a potential therapeutic target. In this study, we found that SCD1 expression in EBV-associated gastric cancer (EBVaGC) was significantly lower than in EBV-negative gastric cancer (EBVnGC) at both cellular and tissue levels.
