Electromagnetic interference (EMI) shielding materials that also possess thermal management capabilities are crucial for safeguarding sensitive information against interception or disruption in electronic countermeasure applications. Furthermore, these materials are adept at maintaining a stable internal temperature within their structural framework, even under the most severe cold conditions. In this work, we fabricated elastic hollow porous polyurethane (HPU) fibers incorporating silver-coated copper nanosheets (Cu@Ag NS) as fillers, which exhibit low mid-infrared emissivity and exceptional electrical conductivity. These fibers were subsequently woven into HPU textile using a shuttle weaving technique, resulting in the textile with superior EMI shielding and excellent thermal management properties. The results indicate that the HPU textile can attain an adjustable EMI shielding effectiveness (SE) ranging from 21.11 to 57.53 dB, depending on the angle between HPU textile and the electric field of the incident electromagnetic wave. The HPU textile exhibits a thermal conductivity of 0.06 Wm(-1)K(-1), offering excellent thermal insulation. Moreover, it demonstrates an elongation of 490 %, underscoring its exceptional flexibility. These outstanding EMI shielding capabilities, combined with its adaptable thermal response and superior thermal management properties, make the HPU textile highly appropriate for use in wearable devices and architectural applications.

Patients diagnosed with radioiodine refractory thyroid cancer (RAIR-TC) are not amenable to novel I-131 therapy due to the reduced expression of sodium iodide symporter (Na+/I- symporter, NIS) and/or the impairment of NIS trafficking to the plasma membrane. RAIR-TC patients have a relatively poor prognosis with a mean life expectancy of 3-5 years, contributing to the majority of TC-associated mortality. Identifying RAIR-TC patients and selecting proper treatment strategies remain challenging for clinicians. In this review, we demonstrate the updated clinical scenarios or the so-called "definitions" of RAIR-TC suggested by several associations based on I-131 uptake ability and tumor response post-I-131 therapy. We also discuss current knowledge of the molecular alterations involved in membrane-localized NIS loss, which provides a preclinical basis for the development of targeted therapies, in particular, tyrosine kinase inhibitors (TKIs), redifferentiation approaches, and immune checkpoint inhibitors.

The resource utilization of red mud (RM) is crucial for the aluminum industry and for addressing environmental concerns. In this study, RM-based slag pellets were prepared through a cold pressing process and used for converter steelmaking. In the pellet preparation experiment, the effects of binder starch and carboxymethyl cellulose sodium (CMC) dosage, moisture content, drying temperature, particle size, and forming pressure on the strength of RM-based pellets were studied. The formation mechanism of RM particles was determined by analyzing the changes in the crystal structure, functional groups, elemental valence state information, and density functional theory calculations. Finally, the environmental benefits of the pellet production process were analyzed. Under the optimal reaction conditions, the compressive strength of RM pellets prepared based on starch and CMC can reach 1162.06 and 1345.6 N/P, which can meet the production needs of the converter. Mechanism analysis shows that organic adhesives adsorb and solidify particles through chemical or hydrogen bonding, resulting in a denser particle structure. RM particles have an excellent slag and phosphorus removal performance. The results of the life cycle assessment clarify the potential contributions of each stage of particle production. The raw materials and transportation distance have significant impacts on the particle production system. The experimental results provide theoretical guidance and a sustainable evaluation for the production of RM slag aggregates.

Nonsuicidal self-injury (NSSI) generally occurs in youth and probably progresses to suicide. An examination of cortical thickness differences (Delta CT) between NSSI individuals and controls is crucial to investigate potential neurobiological correlates. Notably, Delta CT are influenced by specific genetic factors, and a large proportion of cortical thinning is associated with the expression of genes that overlap in astrocytes and pyramidal cells. However, in NSSI youth, the mechanisms underlying the relations between the genetic and cell type-specific transcriptional signatures to Delta CT are unclear. Here, we studied the genetic association of Delta CT in NSSI youth by performing a partial least-squares regression (PLSR) analysis of gene expression data and 3D-T1 brain images of 45 NSSI youth and 75 controls. We extracted the top-10 Gene Ontology terms for the enrichment results of upregulated PLS component 1 genes related to Delta CT to conduct the cell-type classification and enrichment analysis. Enrichment of cell type-specific genes shows that cellular component morphogenesis of astrocytes and excitatory neurons accounts for the observed NSSI-specific Delta CT. We validated the main results in independent datasets to verify the robustness and specificity. We concluded that the brain Delta CT is associated with cellular component morphogenesis of astrocytes and excitatory neurons in NSSI youth.

In this study, a series of semi-interpenetrating network (semi-IPN) structure proton exchange membranes (PEMs) based on linear polyolefins and cross-linked poly(phenylene oxide) (cPPO) was fabricated for fuel cell applications. The newly synthesized membranes exhibit better flexibility and higher chemical and thermal stability than cPPO membrane owing to a semi-IPN structure. After treatment with Fenton's reagent at 80 degrees C for 240 h, all the synthesized semi-IPN membranes (cPPO-[AN-VBIm]x) show a remaining mass of >90%, indicating good oxidation stability. The proton conductivity and fuel cell performance of cPPO-[AN-VBIm](50) membranes (91 mS cm(-1) at 160 degrees C and 514 mW cm(-2) at 140 degrees C, respectively) are better than those of cPPO membranes (51 mS cm(-1) and 87 mW cm(-2), respectively under the same conditions). This study contributes significantly toward membrane research, reporting a facile and efficient method for fabricating high-performance phosphoric acid-doped membranes for high-temperature fuel cell applications that could guide future studies on efficient and practicable high-temperature PEMs.

In this paper, four kinds of recycled concrete with 0 %, 0.5 %, 1.0 %, and 1.5 % glass fiber volume ratios were prepared to investigate the alkali corrosion resistance life of glass fiber recycled concrete in an alkaline environment. The alkali solution erosion test, uniaxial compression test, and scanning electron microscope (SEM) test were carried out, respectively. The results show that glass fiber can reduce the mass loss of recycled concrete in an alkaline environment, improve its compressive strength, and prolong its alkali resistance life. When the volume ratio of glass fiber was 1.0 %, the mass loss was reduced by 0.65 %, the compressive strength was increased by 11.22 %, and the alkali corrosion life was prolonged by 40 days, up to 183 days. Based on the grey degree theory GM(1,1), the compressive strength and corrosion resistance coefficient prediction models of glass fiber recycled concrete were established. The accuracy grade of the compressive strength prediction model and the corrosion resistance coefficient prediction model were level 1 (good), indicating that the accuracy of the prediction model was good, which provided a certain theoretical basis for the research in related fields of glass fiber recycled concrete in an alkaline environment.

BackgroundAcute kidney injury (AKI) is a common complication of sepsis and also a risk factor for progression of chronic kidney disease. NOP2/Sun RNA methyltransferase 3 (NSUN3) is involved in the regulation of sepsis progression. However, the mechanism by which NSUN3 regulates sepsis-associated AKI (SA-AKI) remains unclear. MethodsSA-AKI mouse model and lipopolysaccharide (LPS)-induced injury model in HK-2 cells were constructed. Haematoxylin-eosin staining, quantitative polymerase chain reaction (qPCR), western blotting, cell counting kit 8, flow cytometry, 2 ',7 '-dichlorofluorescein diacetate, enzyme-linked immunosorbent assay, methylation RNA immunoprecipitation-qPCR, actinomycin D and TdT-mediated dUTP Nick-End Labelling staining assays were utilised to explore the expression and related mechanism of NSUN3 in the SA-AKI models. ResultsThe expression of NSUN3 and tumour necrosis factor receptor-associated factor (TRAF)-interacting protein with forkhead-associated domain (TIFA) was upregulated in mice with SA-AKI and LPS-induced HK-2 cells. Knockdown of NSUN3 inhibited LPS-induced injury in HK-2 cells. Mechanically, NSUN3 increased TIFA mRNA stability and upregulated its expression through m5C modification. Moreover, knockdown of NSUN3 was found to alleviate LPS-induced HK-2 cell injury and SA-AKI in mice by reducing TIFA expression. ConclusionNSUN3 aggravates SA-AKI by stabilising TIFA mRNA through m5C, indicating that NSUN3 may be a biomarker for SA-AKI.

In large-scale centralised pig farming, object detection algorithms can accurately track and monitor each pig. However, a significant proportion of current detection methods are based on visible images, and the colour differences between different pig breeds limit the applicability of the models. Furthermore, complex background interference, low illumination conditions, or high illumination intensity noise in visible scenes can likewise lead to reduced accuracy during detection. Therefore, we propose a cross-domain encoder based on the self-attention and design the IVDETR model, which integrates features from infrared and visible light images for pig object detection. In order to facilitate the training and evaluation of the model, we constructed a comprehensive, standardised infrared-visible light dataset for the first time. The experimental outcomes demonstrated that the detection accuracy was increased from 0.939 to 0.998 in a real pig breeding environment. © 2024 IEEE.

In accordance with the bending deformation of titanium alloy profile generated by hot extrusion, the hot stretch straightening assisted by resistance heating is an effective strategy to improve the straightness accuracy. In order to reveal the heat transfer behavior and deformation mechanism of titanium alloy profile during hot straightening, this study focuses on Ti-6.5Al-2Zr-1Mo-1 V alloy thin-walled T-shaped profile with unequal thicknesses. The flow stress curves of profile within temperatures from 400 to 800 celcius, strain rate at 5 center dot 10(-4) s(-1) were obtained by uniaxial tensile tests. The thermal boundary conditions between profile and air were determined by using inverse analysis experiment. Then, the thermal-electrical-mechanical multi-field coupling numerical simulation model was established. The temperature distribution, stress distribution, and deformation of profile were investigated systematically. The results show that the non-uniform temperature field with low temperature in thinner wall region and high temperature in thicker wall region would form during resistance heating. The stress distribution of stretch straightening process was determined by the temperature distribution and the initial bending shape of profile jointly, thereby affecting the springback deflection and direction after unloading. The established numerical simulation models, which have been verified by process experiments, could lay foundation for the prediction and process optimization in hot stretch straightening of titanium profile.
