摘要：
Due to the problems of low welding efficiency, large heat-affected zone, and poor welding quality in the process of welding thin-walled titanium tubes by argon arc welding, there are few studies on the use of high-frequency induction welding (HFIW) of thin-walled titanium alloy tubes. The evolution law of weld microstructure and mechanical properties of the thin-walled titanium tube needs to be further studied because of rapid welding speed and the small heat-affected zone of HFIW. Therefore, a novel manufacturing method via high-frequency induction welding is proposed in this paper to solve the existing problems. With an industrial-grade titanium TA2 tube (wall's thickness is 0.5 mm) as the research object, a comparative study is conducted in this research to examine the morphology, microstructure, microhardness, and tensile characteristics of welded joints at different welding power. The findings demonstrated a significant efficacy of HFIW in resolving these challenges. The mechanical properties and microstructue of heat-affected zone (HAZ) were characterized. The lowest hardness is measured at 202 HV, while the base material was recorded as 184 HV, when the welding speed of HFIW is set at 50 m/min. Meanwhile, the heat-affected zone has the highest hardness at 224 HV, a tensile strength of 446.8 MPa and a post-fracture elongation of 16%. The results showed that HFIW can not only greatly improve the welding efficiency, significantly improve the microstructure of weld joint and HAZ, and improve the mechanical properties of thin-walled titanium pipe, but also provide a highly feasible welding method for welding ultra-thin-walled pipes.
摘要：
Naphthalimide‐based glycopolymeric nanoparticles with dual tumor‐targeting ability from glucose‐segment and phenylboronic ester modification were designed and used as pH sensitive and AIEgen fluorescent probes for selective imaging of tumor cells. Abstract A series of functional glycopolymer nanoparticles with 1,8‐naphthalimide motif was designed, synthesized and applied for tumor cell imaging. With the pH‐sensitive and aggregation‐induced emission (AIE) effect of the 1,8‐naphthalimide fluorescent probe, the presence of glucose‐based glycopolymers enhanced its water‐solubility and biocompatibility. Owing to the dual tumor‐targeting effects of the dense glucose part and the boronic ester modification, the obtained glycopolymers showed high affinity to tumor cells, with a much faster staining rate than normal cells, indicating a great potential for diagnosis and treatments of cancers.

摘要：
The novel two-dimensional (2D) channel membranes have great potential for effective Li+/Mg2+ separation due to the rapid ion transport and precise adjustment of their channels. However, the solution composition greatly affects the control of channel height, resulting in an unsatisfactory selectivity performance. Herein, the 2D montmorillonite membranes are used to understand the causes of channel instability and explore the effective solutions. It is found that the changes in solution component can enlarge the channel height by changing the cross-linking constraint of Fe3+ between MMT nanosheets, thus leading to a weak sieving effect. To improve the channel constraint and its Li+/Mg2+ separation, the end face and interfacial layer constraint of nanosheets are proposed. As an effective strategy to strengthen the constraint effect, glutathione can modify the end faces of nanosheets and enhance the mutual binding force between them through its oxidative transformation. Besides, the construction of an interfacial layer can also limit channel swelling by altering the membrane hydration and wetting. These strategies will also form a synergistic regulatory effect. Consequently, a superior membrane is obtained and presents an improved selectivity of 8.89 at 100:1 Mg2+/Li+ ratio. These innovative approaches offer a valuable framework for creating high-performance 2D channel membranes, which can also support their wider application in the Li+/Mg2+ separation.
摘要：
Ammonia control has attracted attention due to the possibility for fine particles (PM(2.5)) mitigation. Based on past decade ammonia emissions assessments and future predictions, this study seasonally evaluated the ammonia emissions reduction potential in 2025 and 2030 in Wuhan, a Central China megacity, according to the short-term and long-term predictable policies. Furthermore, combined with the reduction potential, PM(2.5) components observation and thermodynamic model, the effectiveness of implementing ammonia emission control to reduce PM(2.5) by 2025 and 2030 was explored seasonally. Results indicated that the total ammonia emissions are expected to decrease by 19.6-33.9% in 2025 and 2030 under positive reduction scenarios, or increase by 8.9-11.7% in the absence of any intervention. Livestock holds the largest potential for reducing ammonia emissions accounting for 46.4-52.5% of the total. Improvement of human excrement management in rural regions also contributes a 35-37% potential. Despite the implementation of exhaust requirements, ammonia emissions from vehicles in 2030 are expected to continue to increase by 55.3% and 23.5% under the regular (S1) and enhanced (S2) reduction strategy scenarios, respectively. Seasonally, the most potential source of ammonia reduction in spring, summer and fall remains livestock. While in winter, non-agricultural sources dominate the reduction potential. Further results indicated that by ammonia control is expected to decrease PM(2.5) concentration up to 5% (less than 1 μg m(-3)) in 2025-2030. Despite the better effectiveness in winter, ammonia control won't be an effective way to reduce PM(2.5) in Central China in future, from the management policies and areal ammonia-rich conditions.

摘要：
Respiration plays a crucial role in the physiological development of embryos throughout the entire incubation process and serves as a vital indicator for discerning unfertilized eggs and embryos that have stopped development. This article explores the relationship between egg respiration, fertilization status, and chicken embryo viability. First, it studied the changes in respiration of fertilized and unfertilized eggs during the early stages of incubation (Day 1–3) and found that the CO2 production of fertilized eggs gradually increased, while those of unfertilized eggs gradually decreased. Moreover, significant differences in respiration between fertilized and unfertilized eggs were observed on the second day of incubation. Next, we employed Random Forest (RF), Logistic Regression (LR), and Support Vector Machine (SVM) models to differentiate between fertilized and unfertilized eggs. Notably, the SVM algorithm exhibited exceptional performance in discriminating between fertilized and unfertilized eggs, achieving a remarkable test set accuracy of 98.41 %. Finally, a Bayesian algorithm was applied to classify embryos as either dead, weak, or viable in middle and later stages of incubation. Bayesian discriminant analysis yielded compelling results, achieving a 100 % detection rate for deceased embryo eggs. The outcomes of this study provide a robust theoretical foundation and empirical data to advance non-destructive testing methodologies for poultry eggs.
摘要：
This study proposed a new curing agent consisting of slag and desulfurization gypsum industrial waste to solidify Cr(VI)-contaminated soils and prevent its migration and bioaccumulation in the ecosphere. The curing agent dosage of 10-30% resulted in a Cr(VI) toxic leaching concentration, compressive strength, and hydraulic conductivity range of 0.118-5.824 mg/L, 2.70-10.22 MPa, and 1.70 x 10-9-1.37 x 10-6 cm/s, respectively. Following four dry and wet cycles, the dosage of the curing agent was found to be 20-30% to achieve minimum environmental safety requirements. Cr(VI) in the cured specimens mainly existed as CrO42-, or acid salt, in which a portion was changed to Cr(III) during precipitation or directly was encased in the silica-alumina mesh structure. The adsorption capacity of hexavalent chrome on the outer of the hydration product groups was insignificant owing to the electronegativity. Hence, the Cr(VI) was solidified by hydrides such as C-S(A)-H and calcium alumina inclusions. Calcite, quartz, and several zeolite-like substances were also found to be colloidal in the pores to block Cr(VI).

摘要：
In this study, amine vapor-sensitive films with ratiometric fluorescence attributes were developed. The pH-sensitive fluorescein 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) and its tetraphenylethylene derivative (TPB) were selected as ratiometric indicators and incorporated into a polyvinyl alcohol (PVA) matrix to produce HPTS/TPB-PVA films. The films responded well to amine vapors, and the interference of aromatic vapors did not substantially affect the fluorescence signals of the films. Under UV light at a wavelength of 365 nm, the fluorescence of the films changed from dark pink to light pink and finally to yellow when the freshness of the fish was visually checked during storage. In addition, the color difference values of the films showed a positive correlation with the total volatile basic nitrogen (TVB-N), ranging from 12.7 to 24.8 mg/100 g at 25 °C and 8.4 to 25.6 mg/100 g at 4 °C, respectively. This indicates that fluorescent films have good potential for quantifying fish freshness in the near future when connected to an automatic data processing system based on color differences.

摘要：
Protein hydrolysate has been a premium protein source in animal feed and is more easily absorbed in animal intestines compared with crude protein, which has a higher rate of pure protein and free amino acids with a high protein efficiency ratio. Previous studies have shown that black soldier fly larvae have been considered one of the most promising proteins for replacing fish meal, especially in the pet market. Recently, the synthesis and functional identification of protein hydrolysate from black soldier fly larvae (BSFP) have received a great deal of attention. In addition, schizochytrium is a marine microalga which has a high content of lipids and polyunsaturated fatty acids (PUFAs), especially an abundant docosahexaenoic (DHA) concentration. Previous research has demonstrated that schizochytrium is promisingly able to substitute for soybean and fish oil in feed and possesses some physiological functions. The objective of this research was to evaluate palatability, plasma biochemistry, antioxidative and anti-inflammatory capacity, and immune levels in cats by feeding supplementing inclusion of different levels of a mixture of protein hydrolysate from black soldier fly larvae and schizochytrium (BSFPs) in diets. In the feed experiment, a total of 24 adult cats (12 females and 12 males; BW: 3.02 +/- 0.06 kg) were randomly divided into four groups: (1) diet with chicken and fish meal as primary protein resource (CON); (2) diet with 5% BSFPs replacing chicken meal, fish meal, chicken oil, and fish oil (5% BSFPs); (3) 10% BSFPs; and (4) 15% BSFPs. The body weight and feed intake were recorded, and a blood sample was collected for analysis. In the palatability experiment, three diets containing 5%, 10%, and 15% BSFPs were evaluated by comparing with CON. These results suggested that different levels of BSFPs could improve palatability in cat diets by enhancing the first sniff, the first bite, and feed intake (p < 0.05). However, no significant influence existed in body weight and average daily feed intake (p > 0.05). In comparison to the CON group, 5% and 15% BSFPs significantly increased the total protein content, and all treatment groups decreased the triglyceride content and enhanced the calcium concentration in plasma; in addition, the activity of aspartate aminotransferase and alanine aminotransferase and the content of creatinine and urea nitrogen were significantly reduced by the supplementation inclusion of BSFPs in the diets (p < 0.05). The enzyme activity of glutathione peroxidase was dramatically enhanced by the supplementation of 10% and 15% BSFPs in diets compared with the CON diet, and the activity of superoxide dismutase was increased and the malondialdehyde concentration was remarkably reduced in all three treatments (p < 0.05). Compared with the CON group, different levels of BSFPs in the diets significantly increased the immunoglobulin A content in plasma; similarly, the immunoglobulin G concentration was significantly enhanced by the supplementation of 10% and 15% BSFPs in the diets (p < 0.05). Furthermore, the interleukin-1 beta content was significantly reduced in the inclusion of 10% and 15% BSFPs in the diets, and 15% BSFPs remarkably decreased the content of interleukin-8 in plasma compared with the CON diet (p < 0.05). To sum up, the supplementation of different levels of BSFPs exhibited a positive effect on palatability and enhanced the antioxidant, anti-inflammatory, and immune capacity. Particularly, the addition levels of 10% and 15% BSFPs were more effective in antioxidation, anti-inflammation, and immunity.

摘要：
Existing deep learning methods for facial emotion recognition only focus on optimizing network structures, utilizing fixed receptive fields for different images, and relying on feature extraction based on a single scale of receptive fields. However, this approach fails to fully capture the most critical facial regions. To address this limitation, this paper presents a novel technique for facial emotion recognition that employs a selective kernel network. The proposed method introduces a dedicated module called the selective kernel network, which is trained using transfer learning. This module incorporates various components, such as a selective attention mechanism and channel-wise independent feature extraction and fusion. These components allow for the extraction of feature information from key facial regions. Unlike other methods, the selective convolutional kernel network extracts features with multiple scales of receptive fields and adapts to different spatial positions using a multilayer perceptron. This adaptability enhances useful features and suppresses noise. After extracting the features, they are combined, and the classification outcome is computed using the softmax function. Experimental results demonstrate that the suggested approach achieves an accuracy of 88.4 and 92.1% on the RAF-DB and KDEF datasets, respectively. These results confirm the efficacy of the proposed technique in comprehensively capturing the most crucial facial regions. Moreover, compared to alternative methods, this technique exhibits superior accuracy and enhanced resilience.

摘要：
Inadequate Se intake can enhance vulnerability to certain health risks, with supplementation lessening these risks. This study investigated the bioavailability of Se and Se species in five Se compounds and in Se-rich Cardamine violifolia using in vitro digestion coupled with a Caco-2 cell monolayer model, which enabled the study of Se transport and uptake. Translocation results showed that SeCys(2) and MeSeCys had high translocation rates in C. violifolia leaves (CVLs). The uptake rate of organic Se increased with time, and MeSeCys exhibited a higher uptake rate than that for SeCys(2) and SeMet. The translocation mechanisms of SeMet, Se(IV), and Se(VI) were passive transport, whereas those of SeCys(2) and MeSeCys were active transport. The bioavailability of organic Se was higher than that of inorganic Se, with a total Se bioavailability in CVLs of 49.11%. This study would provide a theoretical basis for the application of C. violifolia in the functional food.

摘要：
Deep eutectic solvents (DES) were prepared using urea (U) and acrylamide (AM) as hydrogen bond donors (HBD) and choline chloride (ChCl) as hydrogen bond acceptor (HBA), and polyethylene glycol (PEG) was selected as a filler and uniformly dispersed in DES to prepare PEG/P(U-AM-ChCl) composite hydrogels by light polymerization. The composite hydrogels were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The effects of the content of PEG on the swelling properties, mechanical properties and fatigue resistance of the composite hydrogels were investigated. The results showed that the compressive strength and fatigue strength of the composite hydrogels were gradually enhanced with the increase of the PEG content in the composite hydrogels, in which the maximum compressive strength of the hydrogels with 1 wt% PEG added was increased by 1.86 times. The composite hydrogel had excellent swelling properties, and the equilibrium swelling degree of the hydrogel with 1 wt% PEG added reached 10.15. Meanwhile, the PEG/P(U-AM-ChCl) composite hydrogel had excellent self-healing properties, and the self-healing rate of the composite hydrogel with a PFG content of 1 wt% could reach 91.93% after 48 hours of healing. This study provides a convenient and efficient method to prepare composite hydrogels with superior swelling properties and self-healing properties. Deep eutectic solvents (DES) were prepared using urea (U) and acrylamide (AM) as hydrogen bond donors and choline chloride (ChCl) as hydrogen bond acceptor. Polyethylene glycol (PEG) was selected as a filler and uniformly dispersed in DES to prepare PEG/P(U-AM-ChCl) composite hydrogels.
摘要：
Fungal symbionts can improve plant tolerance to salt stress. However, the interaction of epiphytic Fusarium oxysporum and Fusarium fujikuroi with the tolerance of the invasive plant Ipomoea cairica against saline coastal habitats is largely unknown. This study aimed to investigate the interaction of the mixture of the two epiphytic fungi with salt tolerance of I. cairica. Surface-sterilized I. cairica cuttings inoculated (E+) and non-inoculated (E-) with the fungal mixture were cultivated with 2, 3, and 5 parts per thousand (PPT) of NaCl solutions to simulate mild, moderate, and severe salt stress, respectively. The hydroponic experiment showed that the growth inhibition and peroxidation damages of E+ and E- cuttings were aggravated with salinity. Noteworthily, E+ cuttings had higher peroxidase (POD) and catalase (CAT) activities, chlorophyll content, total biomass, aboveground biomass, total shoot length and secondary shoot number, but lower root-to-shoot ratio than E- cuttings under 2 and 3 PPT NaCl conditions. Moreover, E+ had higher superoxide dismutase (SOD) activity and proline content but lower belowground biomass and malondialdehyde (MDA) content than E- cuttings under 3 PPT NaCl condition. However, lower SOD, POD, and CAT activities, and chlorophyll content, but higher MDA content occurred in E+ cuttings than in E- cuttings under 5 PPT NaCl condition. These findings suggested that the mixture of the two epiphytic fungi increased salt tolerance of I. cairica mainly through increasing its antioxidation ability and chlorophyll stability under mildly and moderately saline conditions, but decreased salt tolerance of this plant in an opposite way under severely saline conditions.

摘要：
Thiabendazole (TBZ), a highly toxic phosphorothioate insecticide commonly used in postharvest fruit management, has the potential to cause detrimental effects on human health as an endocrine disruptor. In this study, an electrochemical sensor was developed to detect TBZ by modifying MoS(2) on silver nanowires (Ag NWs@MoS(2)) and integrating them onto a glassy carbon surface. Cyclic voltammetry revealed that TBZ underwent an irreversible, diffusion-controlled process on Ag NWs@MoS(2), leading to a two-fold increase in peak current compared to unmodified MoS(2). Square wave voltammetry facilitated TBZ detection, and the sensor exhibited a linear range of 0.05-10μM with a high coefficient of determination (R(2)=0.9958) and a limit of detection (LOD) of 1.75nM (signal-to-noise ratio=3). The sensor's applicability for food safety monitoring was verified through TBZ analysis in pear and apple samples, achieving recoveries of 95.5-103.6% with RSDs in the range of 1.98-3.25%.

摘要：
Anti-wear performance is a crucial quality of lubricants, and it is important to conduct research into the structure-activity relationship of anti-wear additives in bio-based lubricants. These lubricants are eco-friendly and energy-efficient. A literature review resulted in the construction of a dataset comprising 779 anti-wear properties of 79 anti-wear additives in rapeseed oil, at various loadings and additive levels. The anti-wear additives were classified into six groups, including phosphoric acid, formate esters, borate esters, thiazoles, triazine derivatives, and thiophene. Logistic regression analysis revealed that the quantity and kind of anti-wear agents had significant effects on the anti-wear properties of rapeseed oil, with phosphoric acid being the most effective and thiophene being the least effective. To identify the specific structural data that affect the anti-wear capabilities of additives in bio-based lubricants of rapeseed oil, a random forest classification model was developed. The results showed a 0.964 accuracy (ACC) and a 0.931 Matthews Correlation Coefficient (MCC) on the test set. The ranking of importance and characterization of MACCS descriptors in the model confirms that anti-wear additives with chemical structures containing P, O, N, S and heterocyclic groups, along with more than two methyl groups, improve the anti-wear performance of rapeseed oil. The application of data analysis and machine learning to investigate the classifications and structural characteristics of anti-wear additives in rapeseed oil provides data references and guiding principles for designing anti-wear additives in bio-based lubricants.
摘要：
BACKGROUND: Rosmarinic acid (RA), a polyphenol from edible-medical Lamiaceae herbs, is known to possess a variety of pharmacological activity, like anti-inflammatory, hepatoprotective and immunoregulation activities. METHODS AND RESULTS: Hereon, we investigated the anti-allergic activity of RA on immunoglobulin E (IgE)-mediated anaphylaxis responses in rat basophilic leukemia (RBL)-2H3 mast cell. RA hindered the morphological changes of IgE-induced degranulated RBL-2H3 cells. The release of two key biomarkers (β-hexosaminidase (β-HEX) and histamine) of IgE-induced degranulated mast cells was also remarkably down-regulated by RA intervention in a dose dependent manner. Moreover, RA inhibited IgE-induced ROS overproduction and flux of intracellular Ca(2+) in IgE-mediated degranulated mast cells. The q-PCR analysis showed that the expressions of genes (COX 2, PGD 2, LTC 4, HDC, Nrf2, HO-1 and NQO1) involved in MAPK and oxidative stress signaling pathways were significantly regulated by RA intervention. Moreover, the degranulation inhibitory effect of rosmarinic acid was investigated on the anti-DNP IgE/DNP-HSA induced passive cutaneous anaphylaxis (PCA) mice model in vivo. It showed that RA significantly inhibited the PCA reaction and allergic edema of ears in anti-DNP IgE/DNP-HSA stimulated mice. CONCLUSION: These findings suggest that RA has the potential to be used as a therapeutic candidate for allergic diseases by inhibiting mast cell degranulation. This indicates a possible role for RA in managing allergic reactions and related conditions.
