摘要：
Myocardial ischemia-reperfusion (MI/R) not only causes cardiac damage, but also causes severe renal damage. T8 is the 8th peptide identified by peptiomics in digested yak milk dregs and our previous studies showed that T8 had strong antioxidant activity. This study evaluated the protective effects and molecular mechanisms of MI/R-induced kidney injury in rats. Our results indicated that peptide T8 could increase ejection fraction (EF) and shortened fraction (FS), and degraded ST segment elevation, which ameliorated cardiac function in the MI/R rats. Peptide T8 could increase activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX), and decreased the contents of malondialdehyde (MDA), serum creatinine (Scr) and blood urea nitrogen (BUN), which could ameliorate renal insufficiency. Peptide T8 and kidney injury-related targets in the MI/R-damaged rats were obtained from network pharmacology analysis. KEGG analysis revealed that T8 might affect 54 signaling pathways and 13 key targets were obtained by PPI network analysis. The binding affinity of peptide T8 to Keap1 was found to be the strongest by molecular docking analysis. In the H2O2-induced HEK293 cell model, peptide T8 decreased reactive oxygen species (ROS) content and changed the expression ratio of Bcl-2 and Bax, thereby inhibiting mitochondria-dependent apoptosis. Further studies indicated that T8 could regulate Nrf2 pathway and downstream target genes such as NQO1, which could reduce oxidative stress-induced damage. These results suggest that peptide T 8 can exert renal protection via regulating Nrf2 pathway and apoptosis-related genes.

摘要：
Lithium aluminum layered double hydroxide chlorides (LADH-Cl) have been widely used for lithium extraction from brine. Elevation of the performances of LADH-Cl sorbents urgently requires knowledge of the composition-structure-property relationship of LADH-Cl in lithium extraction applications, but these are still unclear. Herein, combining the phase equilibrium experiments, advanced solid characterization methods, and theoretical calculations, we constructed a cyclic work diagram of LADH-Cl for lithium capture from aqueous solution, where the reversible (de)hydration and (de)intercalation induced phase evolution of LADH-Cl dominates the apparent lithium "adsorption-desorption" behavior. It is found that the real active ingredient in LADH-Cl type lithium sorbents is a dihydrated LADH-Cl with an Al:Li molar ratio varying from 2 to 3. This reversible process indicates an ultimate reversible lithium (de)intercalation capacity of ∼10 mg of Li per g of LADH-Cl. Excessive lithium deintercalation results in the phase structure collapse of dihydrated LADH-Cl to form gibbsite. When interacting with a concentrated LiCl aqueous solution, gibbsite is easily converted into lithium saturated intercalated LADH-Cl phases. By further hydration with a diluted LiCl aqueous solution, this phase again converts to the active dihydrated LADH-Cl. In the whole cyclic progress, lithium ions thermodynamically favor staying in the Al-OH octahedral cavities, but the (de)intercalation of lithium has kinetic factors deriving from the variation of the Al-OH hydroxyl orientation. The present results provide fundamental knowledge for the rational design and application of LADH-Cl type lithium sorbents.

摘要：
In this review, SACs with different metal species and substrates are summarized to investigate the metal−support interaction effects on the persulfate oxidation reaction for water treatments. Abstract With maximum utilization of active metal sites, more and more researchers have reported using single atom catalysts (SACs) to activate persulfate (PS) for organic pollutants removal. In SACs, single metal atoms (Fe, Co, Cu, Mn, etc.) and different substrates (porous carbon, biochar, graphene oxide, carbon nitride, MOF, MoS2, and others) are the basic structural. Metal single atoms, substances, and connected chemical bonds all have a great influence on the electronic structures that directly affect the activation process of PS and degradation efficiency to organic pollutants. However, there are few relevant reviews about the interaction between metal single atoms and substances during PS activation process. In this review, the SACs with different metal species and substrates are summarized to investigate the metal−support interaction and evaluate their effects on PS oxidation reaction process. Furthermore, how metal atoms and substrates affect the reactive species and degradation pathways are also discussed. Finally, the challenges and prospects of SACs in PS‐AOPs are proposed.

摘要：
The adsorption removal of lead (Pb) ions has become a crucial area of research due to the potential health hazards associated with Pb contamination. Developing cost-effective adsorbents for the removal of Pb(II) ions is significantly important. Hence, a novel fluorescent starch-based hydrogel (FSH) using starch (ST), cellulose nanofibrils (CN), and carbon dots (CD) was fabricated for simultaneous adsorption and detection of Pb(II). A comprehensive characterization of FSH, including its morphological features, chemical composition, and fluorescence characteristics, was conducted. Notably, FSH exhibited a maximum theoretical adsorption capacity of 265.9mg/g, which was 13.0 times higher than that of pure ST. Moreover, FSH was employed as a fluorescent sensor for Pb(II) determination, achieving a limit of detection (LOD) of 0.06μg/L. An analysis was further performed to investigate the adsorption and detection mechanisms of Pb(II) utilizing FSH. This study provides valuable insights into the production of a novel cost-effective ST-based adsorbent for the removal of Pb(II) ions.
摘要：
Exploring the single relationship between the inversion degree of spinel and its catalytic performance is a great challenge, but has important significance for further structural design and application. A series of CoMn inverse spinels were prepared and the general formula (Co-1-x(2+) Co-x(3+)) (tet) (Mn-1(3+) Co-x(2+) Co-1-x(3+))(oct)O-4 was deduced through X-ray diffraction refinement to find a decreased inversion degree x as calcination temperature rose. Catalytic oxidation of toluene showed that higher inversion degree (S-300 with x approximate to 0.95) can reach larger conversion rate (90 % at about 250 degrees C for 400 ppm toluene) with greater reaction stability (140 h). Density Functional Theory (DFT) calculations on density of states indicated its metallic nature, and found that the strength of O-p and Transition metal-d orbitals at Fermi energy is positively correlated to the inversion degree, meaning stronger electron migration ability. Along with the adsorption calculation analysis that lattice oxygen species are proved to work dominantly (S-300 with lowest adsorption energy but highest performance), this work uncovered a theoretical insight into inverse spinel oxide, to provide the possibility of elevated oxidation ability through structural control.

Two-echelon capacitated vehicle routing problem;sharing satellite resources;mixed integer linear programming model;adaptive large neighborhood search
摘要：
Collaboration vehicle routing has garnered increasing attention recently because it can help enterprises reduce costs by sharing resources. This paper addresses a novel two-echelon capacitated vehicle routing problem with sharing satellite resources (2E-CVRPSSR), which arises with the development of e-commerce and the Sharing economy in city logistics. In this problem, goods are delivered within a two-echelon routing network, where satellites are used to consolidate and transfer goods between first-and second-echelon routing. Moreover, the second-echelon vehicles can depart from and return to different satellites. A mixed integer linear programming model is first presented, and an adaptive large neighborhood search algorithm with several new search operators and strategies is proposed to solve this problem. The numerical results show that the proposed algorithm can effectively solve the 2E-CVRPSSR. Moreover, an average transportation cost savings of 6.29% can be obtained by sharing satellite resources. In addition, geographic analysis indicates that the layout of the depot, satellites, and customers largely impacts the economic advantages of sharing satellite resources. Specifically, the highest economic benefits are achieved when the satellites are distributed from nearest to farthest from the depot, with customers located between nearby and distant satellites and with satellites of large enough capacity close to the depot.
摘要：
Antimicrobial resistance is a global health security issue of widespread concern. Recent studies have unveiled the potential contribution of non-antibiotics to the emergence of antimicrobial resistance. This study investigated the effect of carbamazepine, a non-antibiotic pharmaceutical, on the fate of antibiotic resistance genes (ARGs) during anaerobic digestion. The results, as revealed by both metagenomic sequencing and absolute quantification, demonstrated that carbamazepine induced the enrichment of ARGs and increased the abundance of ARGs hosts by 1.2-2.1 times. Carbamazepine facilitated microbial aggregation and intercellular communication by upregulating functional genes associated with two-component systems, quorum sensing and type IV secretion systems, thereby increasing the frequency of ARGs conjugation. Furthermore, carbamazepine induced the acquisition of ARGs by pathogens and elevated the overall pathogenic abundance. This study revealed the mechanisms of microbial self-regulation and ARGs transmission under carbamazepine stress, highlighting the potential health risks posed by non-antibiotic pharmaceuticals during the safe disposal of sludge.

摘要：
This paper constructs a comparative analysis framework on how the input-output (IO) model with technical differences affects the calculation of the pollution terms of trade (PTT) and the tests of the pollution haven hypothesis. Specifically, the CO2 terms of trade (CTT) of the world's major economies are calculated based on five IO models, and chain additive structure decomposition analysis (SDA) is conducted to examine the roles of different factors in the changes in CTT. The economic phenomena reflected by the CTT measured by these IO models are found to be different, and a comparative analysis shows that different IO models are suitable for studying different economic problems. Suggestions are provided on the application of different IO models in the calculation of economic indicators and the study of economic issues. Policy makers need to be cautious about policy recommendations based on the results obtained from different IO models.

摘要：
Music genre classification (MGC) is an indispensable branch of music information retrieval. With the prevalence of end-to-end learning, the research on MGC has made some breakthroughs. However, the limited receptive field of convolutional neural network (CNN) cannot capture a correlation between temporal frames of sounding at any moment and sound frequencies of all vibrations in the song. Meanwhile, time–frequency information of channels is not equally important. In order to deal with the above problems, we apply dual parallel attention (DPA) in CNN-5 to focus on global dependencies. First, we propose parallel channel attention (PCA) to build global time–frequency dependencies in the song and study the influence of different weighting methods for PCA. Next, we design dual parallel attention, which focuses on global time–frequency dependencies in the song and adaptively calibrates contribution of different channels to feature map. Then, we analyzed the effect of applying different numbers and positions of DPA in CNN-5 for performance and compared DPA with multiple attention mechanisms. The results on GTZAN dataset demonstrated that the proposed method achieves a classification accuracy of 91.4%, and DPA has the highest performance.

摘要：
The humidity stability and phase transition mechanism of the all-inorganic perovskite CsPbI2Br based on an optimized dual-source co-evaporation preparation process are investigated at the film interface level. It is found that the CsPbI2Br films annealed at 300℃ exhibit a best crystallinity and photoelectric properties. The as-grown CsPbI2Br film is confirmed to be a α phase with a dark brown cubic crystal structure and an average visible transparency of 35.9%. But it will be transformed into its δ phase with a transparent orthorhombic crystal structure and an average visible transparency of 80.3% after a certain amount of moisture exposure. Compared with the α phase film, the electronic structure of the δ phase has also changed significantly with a VBM shift of about 0.32 eV to high binding energy. The results of AR-XPS show that the water molecules in perovskite CsPbI2Br after a moisture exposure only adsorb on the surface rather than penetrate the interior of the lattice. When water molecules adsorb on the lattice surface, halide ions should migrate towards the lattice surface due to their high hydration enthalpy, resulting in halide vacancies within the lattice and causing the reduction of energy barrier for phase transition from α phase to δ phase. So the CsPbI2Br film will transform from its α phase to δ phase induced by water vapor, and this phase transition will be reversed to some extent after another annealing.
摘要：
With the rapid growth of Internet data, recommendation systems have become the basic technology to alleviate information overload. The session-based recommendation (SBR) is a challenging task, and its purpose is to predict user behavior based on anonymous sessions. The existing SBR methods need to be improved in capturing the complex conversion relationship of items. In contrast, Graph Neural Network (GNN) can capture the complex conversion between items by modeling sessions as graph structure data. However, current methods just sort the clicked items within a session based on time, without utilizing the temporal information between sessions, leading to poor recommendation performance. To improve the accuracy of session recommendation (SR), we propose an SBR model based on GNN with Combined Temporal (CT-GNN) information. The proposed CT-GNN model is built based on the time of session occurrence, and it can learn the temporal association relationship between session items to enrich the connection between items. More importantly, based on the diversity problem faced by current SRs, which refers to the tendency of users to engage with popular items and resulting in limited exposure for other items, the CT-GNN model uses the Local Item Representation Learning (LIRL) module to learn users' local preferences. Through the LIRL module, the CT-GNN can capture users' interests, boost item exposure, and increase recommendation diversity. The experimental results show that the CT-GNN model is superior to the state-of-the-art SBR methods, with MRR scores 1.1 %∼3.4 % higher than the best-performing baseline; recall scores 0.9 %∼2.3 % higher than the best-performing baseline, and alleviates the diversity problem faced by SR, greatly improving the speed of model convergence, and the training time is 13.6 %∼20.7 % of the best-performing baseline.
摘要：
Octacosanol, a naturally occurring higher fatty alcohol, possessed numerous biological effects. However, octacosanol limited solubility in water due to its lipophilic nature and large structure, resulting in poor absorption and low bioavailability. To overcome this challenge, we developed a simple, environmentally friendly, and energy-efficient O/W nanoemulsion synthesis process. The nanoemulsion achieved an average droplet size of approximately 30nm, exhibited excellent dispersibility and stability at room temperature for 60days, and showcased robust storage properties insensitive to ambient temperature, pH, NaCl, and sucrose. Remarkably, the preparation process of the nanoemulsion maintained the biological activity of octacosanol while demonstrating significantly enhancing antioxidant activity compared to octacosanol suspension. Additionally, the nanoemulsion displayed negligible cytotoxic effects on Caco-2 cells. Significantly, the octacosanol nanoemulsion exhibited a 5.4-fold enhancement in transmembrane transport efficiency when compared to the suspension in Caco-2 cell monolayers. Additionally, in an in vivo experiment, there was a notable 2.9-fold increase in rat intestinal absorption. These findings could provide valuable insights into the development of octacosanol nanoemulsion, supporting its future applications and paving the way for the design of stable nanoemulsion systems for other lipophilic and sparingly soluble substances.

摘要：
The spin polarization of current plays an important role in the performance of spintronic devices. Therefore, a highly spin-polarized current source has always been explored through various methods. We study the effects of magnetic order on the electronic structures of antiferromagnetic (AFM) MnBi2Te4 films. A significant spin splitting is found in the surface states of a AFM MnBi2Te4 film with three septuple layers (SLs). The AFM film can show typical metallic behavior for spin-down electrons, and exhibit a semiconductor or insulator behavior with a band gap at the Fermi level for spin-up electrons, just like semimetal ferromagnets with theoretical spin polarization up to 100%. We also study that the electron transport in the 3-SLs AFM film with a square potential barrier, we find a highly spin-polarized current can be switched on and off by modulating the barrier height in the film.
摘要：
Sb-based materials exhibit considerable potential for sodium-ion storage owing to their high theoretical capacities. However, the bulk properties of Sb-based materials always result in poor cycling and rate performances. To overcome these issues, pyridine-regulated Sb@InSbS3 ultrafine nanoplates loaded on reduced graphene oxides (Sb@InSbS3@rGO) were designed and synthesized. During the synthesis process, pyridine was initially adopted to coordinate with In3+, and uniformly dispersed In2S3 ultrafine nanoplates on reduced graphene oxide were generated after sulfidation. Next, partial In3+ was exchanged with Sb3+, and Sb@InSbS3@rGO was obtained by using the subsequent annealing method. The unique structure of Sb@InSbS3@rGO effectively shortened the transfer path of sodium ions and electrons and provided a high pseudocapacitance. As the anode in sodium-ion batteries, the Sb@InSbS3@rGO electrode demonstrated a significantly higher reversible capacity, better stability (445 mAh<middle dot>g(-1) at 0.1 A<middle dot>g(-1) after 200 cycles and 212 mAh<middle dot>g(-1) at 2 A<middle dot>g(-1) after 1200 cycles), and superior rate (210 mAh<middle dot>g(-1) at 6.4 A<middle dot>g(-1)) than the electrode without pyridine (355 mAh<middle dot>g(-1) at 0.1 A<middle dot>g(-1) after 55 cycles and 109 mAh<middle dot>g(-1) at 2 A<middle dot>g(-1) after 770 cycles). Furthermore, full cells were assembled by using the Sb@InSbS3@rGO as anode and Na3V2(PO4)(3) as cathode, which demonstrated good cycling and rate performances and exhibited promising application prospects. These results indicate that adjusting the microstructure of electrode materials through coordination balance is A<middle dot>good strategy for obtaining high-capacity, high-rate, and long-cycle sodium storage performances.
