4. NWSP: A Novel Indicator for Ocean–Land Interface Extraction Using Bathymetric LiDAR
- Author

Zhao, Xinglei, Xia, Hui, and Zhou, Fengnian
- Abstract
Because of water-surface uncertainty, green lasers used in airborne bathymetric LiDAR cannot accurately detect the water surface, as they reflect near-water surface penetration (NWSP) into the water column. The existence of the NWSP of a green laser in water is not beneficial for high-accuracy depth measurements; however, it can be useful for ocean–land interface (OLI) extraction. In this study, novel ocean–land discrimination and interface extraction methods based on the NWSPs of green lasers are proposed. First, the NWSPs of different green laser channels are calculated and averaged to obtain a robust NWSP for each laser footprint. Second, a novel NWSP-based ocean–land discriminator is proposed based on the different characteristics of the NWSPs in land and ocean areas. Third, density-based spatial clustering of applications with noise algorithm is used to identify and correct the misclassified points of the NWSP-based ocean–land discriminator, and the OLIs are formed by connecting the land boundary points. Finally, the novel NWSP method is verified using a raw ABL data set collected via Optech coastal zone mapping and imaging LiDAR. The OLIs derived by waveform clustering are used as reference to evaluate the performance of the proposed NWSP method. OLI extraction based on the proposed NWSP method and the traditional point elevation method can reach accuracies of 1.9 and 4.8 m, respectively, in the research area. The proposed NWSP method provides a novel and convenient means for OLI extraction using the NWSPs of green lasers.

Pan, Xia-Hui
- Abstract
Within the context of Gurtin–Murdoch surface elasticity theory, closed-form analytical solutions are derived for an isotropic elastic half-plane subjected to a concentrated/uniform surface load. Both the effects of residual surface stress and surface elasticity are included. Airy stress function method and Fourier integral transform technique are used. The solutions are provided in a compact manner that can easily reduce to special situations that take into account either one surface effect or none at all. Numerical results indicate that surface effects generally lower the stress levels and smooth the deformation profiles in the half-plane. Surface elasticity plays a dominant role in the in-plane elastic fields for a tangentially loaded half-plane, while the effect of residual surface stress is fundamentally crucial for the out-of-plane stress and displacement when the half-plane is normally loaded. In the remaining situations, combined effects of surface elasticity and residual surface stress should be considered. The results for a concentrated surface force serve essentially as fundamental solutions of the Flamant and the half-plane Cerruti problems with surface effects. The solutions presented in this work may be helpful for understanding the contact behaviors between solids at the nanoscale. [ABSTRACT FROM AUTHOR]

- Abstract
As a promising high-energy-density cathode material for lithium-ion batteries, the application of FeF3is significantly impeded by its sluggish kinetics. In this study, we propose a straightforward method to fabricate quasi-two-dimensional (quasi-2D) oxygen-doped FeF3nanosheets through the thermal decomposition and liquid-phase exfoliation of commercial FeF3·3H2O. During the thermal decomposition process, some fluorine atoms are substituted by oxygen atoms, resulting in enhanced electrical conductivity and a reduction in the dissociation energy of Fe–F bonds. In addition, the quasi-2D geometrical feature reduces the diffusion length of Li ions. Consequently, this free-standing electrode delivers a high specific capacity (∼600 mAh g–1at a low current density of 0.03 A g–1), a stable cycling performance over 200 cycles at a current density of 0.3 A g–1(with a capacity retention of 82%), and excellent rate capability (350 mAh g–1at 2 A g–1). A more profound insight into the kinetics of this electrode reveals that Li ions preferentially diffuse along the thickness of the non-layered nanosheets, significantly contributing to the outstanding rate performance. Thus, this study tackles the kinetic challenges of FeF3in terms of the electronic and geometrical structures, offering valuable insights for the development of high-performance electrode materials based on the conversion reaction mechanism.

- Abstract
Spinel LiMn2O4cathode possesses open three-dimensional ion transport channels, high safety, and abundant resources, making it a promising candidate for high-power lithium-ion batteries. However, spinel LiMn2O4inevitably faces serious challenges of manganese dissolution and irreversible phase transitions during the electrochemical process, leading to rapid capacity decay and limiting its rate performance. Herein, we report a simple two-step solid-state sintering method to realize Li+and PO43–codoping synergy in spinel LiMn2O4. It is found that PO43–doping not only expands the lattice parameters of the material, enhancing its charge-transfer kinetics but also increases the relative content of active Mn3+, improving the specific capacity of spinel LiMn2O4. Meanwhile, Li+doping effectively enhances the stability of the spinel structure, and the irreversible phase transition from cubic phase to tetragonal phase could be effectively suppressed in spinel LiMn2O4. Consequently, benefiting from the synergistic effect of Li+and PO43–codoping, the optimally codoped spinel LiMn2O4electrode delivers high specific discharge capacities of 116 and 102 mA h g–1at 1 and 20C, respectively, and achieves 78.1% capacity retention after 1000 cycles at 5C. This strategy provides an effective modification approach to developing advanced electrode materials for lithium-ion batteries.

- Abstract
[Display omitted] • Nutritional support is an essential step to prevent muscle loss in aging process. • Fish oil and wheat oligopeptide had protective effects against sarcopenia in aging. • The combined intervention inhibits skeletal muscle atrophy by regulating protein expression. • The combined intervention promotes protein synthesis and skeletal muscle regeneration. • The combined intervention also reduces inflammation, oxidative stress and blood lipid. Nutritional support is potentially considered an essential step to prevent muscle loss and enhance physical function in older adults. This study aimed to assess the role of potential nutritional strategies, i.e., fish oil-derived ω-3 polyunsaturated fatty acids (PUFAs), wheat oligopeptide and their combined intervention, in preventing and reversing sarcopenia in aging process. One hundred 25-month-old Sprague-Dawley rats were randomly divided into 10 groups, and 10 newly purchased 6-month-old rats were included in young control group (n = 10). Fish oil (200, 400 or 800 mg/kg body weight), wheat oligopeptide (100, 200 or 400 mg/kg body weight), fish oil + wheat oligopeptide (800 + 100, 400 + 200 or 200 + 400 mg/kg body weight) or the equal volume of solvent were administered daily by gavage for 10 weeks. The effects of these interventions on natural aging rats were evaluated. All intervention groups had a significant increase in muscle mass and grip strength and reduction in perirenal fat weight when compared to the aged control group (P < 0.05). The results of biochemical parameters, magnetic resonance imaging, proteomics and western blot suggested that the combination of wheat oligopeptide and fish oil-derived ω-3 PUFA, especially group WFM 2 (400 + 200 mg/kg body weight fish oil + wheat oligopeptide), was found to be more effective against aging-associated muscle loss than single intervention. Additionally, the interventions ameliorated fatty infiltration, muscle atrophy, and congestion in the intercellular matrix, and inflammatory cell infiltration in muscle tissue. The interventions also improved oxidative stress, anabolism, hormone levels, and inflammatory levels of skeletal muscle. The combination of fish oil-derived ω-3 PUFA and wheat oligopeptide was found to be a promising nutritional support to prevent and reverse sarcopenia. The potential mechanism involved the promotion of protein synthesis and muscle regeneration, as well as the enhancement of muscle strength. [ABSTRACT FROM AUTHOR]

- Abstract
Hypertension is a global health issue with increasing prevalence. This study aimed to understand the epidemiological characteristics and influencing factors of hypertension in rural Chinese populations and help develop effective prevention and control strategies. This cross-sectional study used database from the Early Diagnosis and Early Treatment Project of Esophageal Cancer conducted in a rural population from September 2012 to December 2017. A total of 10,111 subjects aged 35–75 years residing in Huai'an District, Huai'an City, Jiangsu Province for at least three years were included. Unconditional univariate and multivariate logistic regression models were performed to evaluate the association between socio-demographic information, lifestyle habits, dietary characteristics and the risk of hypertension. The prevalence of hypertension was 34.32 % in this rural population. Men and older individuals are more likely to have hypertension when compared with women and young individuals, respectively. Factors associated with an increased risk of hypertension included: fast eating speed, a high-salt diet (both currently and ten years ago), a high-spicy diet ten years ago, high BMI, poor educational attainment, preference for fatty meats, hot diet, green tea drinking, intake of pickled potherb mustard and corn flour, family smoking and alcohol consumption. Light smoking in males, consumption of fruits, adzuki bean, and pork liver were associated with reduced risk of hypertension. The study identified some factors, including eat habits and lifestyle, associated with hypertension risk, and highlighted the need for targeted policies and interventions in rural China to address potential risk factors for hypertension. • Light smoking was associated with a reduced risk of hypertension in males. • Drinking was associated with an increased risk of hypertension in both sexes. • Green tea was associated with an increased hypertension risk in this population. • The impact of daily choices (lifestyle and diet) on blood pressure is emphasized.

- Abstract
Layered oxide cathodes of sodium-ion batteries (SIBs) are considered promising candidates due to their fascinating high capacity, good cyclability, and environmental friendliness. However, the air sensitivity of layered SIB cathodes causes high electrode manufacturing costs and performance deterioration, hampering their practical application. Herein, a commercial O3-type layered Na(Ni1/3Fe1/3Mn1/3)O2(NNFM) material is adopted to investigate the air corrosive problem and the suppression strategy. We reveal that once the layered material comes in contact with ambient air, cations migrate from transition metal (TM) layers to sodium layers at the near surface, although Na+and TM ions show quite different ion radii. Experimental results and theoretical calculations show that more Ni/Na disorder occurs in the air-exposed O3-NNFM materials, owing to a lower Ni migration energy barrier. The cation mixing results in detrimental structural distortion, along with the formation of residual alkali species on the surface, leading to high impedance for Na+diffusion during charge/discharge. To tackle this problem, an ultrathin and uniform hydrophobic molecular layer of perfluorodecyl trimethoxysilane is assembled on the O3-NNFM surface, which significantly suppresses unfavorable chemistry and structure degradation during air storage. The in-depth understanding of the structural degradation mechanism and suppression strategy presented in this work can facilitate high-energy cathode manufacturing from the perspective of future practical implementation and commercialization.

- Abstract
Forsythia suspensa, belonging to the deciduous shrubs of the Luteaceae family, a traditional Chinese medicine, has effects of alleviating swelling, clearing heat, detoxification and promoting blood circulation. The leaves of F. suspensacontain multiple chemical components and have a long history of use in folk medicines and health foods. The purpose of this study was to explore the effects of forsythin extract from F. suspensaleaves on intestinal microbiota and short-chain fatty acid (SCFA) content in rats with obesity induced by a high-fat diet. Forsythin extract in F. suspensaleaves increased the abundance of the intestinal microbiota, ameliorated intestinal microbiota disorders and inhibited the increase in total SCFA content in the intestinal tract in rats with obesity induced by a high-fat diet. These results suggested that forsythin extract in F. suspensaleaves may slow the development of obesity induced by a high-fat diet; thus, its active components and efficacy are worthy of further study.

Based on the measurements of petrological, petrophysical and elastic properties of the samples of different sedimentary facies in the fourth member of Sinian Dengying Formation (Deng 4 Member) in the Sichuan Basin, the diagenetic processes of reservoirs of different sedimentary facies and their controls on the petrophysical properties were discussed. The results show that cracks and mineral composition jointly control the petrophysical properties, and both are significantly influenced by sedimentary environment and diagenesis. The microbial dolomite of mound-shoal facies mainly experienced multi-stage dolomitization, penecontemporaneous dissolution, tectonic rupture and hydrothermal/organic acid dissolution processes, giving rise to cracks and dissolved pores. The grannular dolomite of inter-mound-shoal bottomland or dolomitic lagoon facies mainly underwent mechanical compaction, burial dolomitization and tectonic-hydrothermal action, creating cracks and intercrystalline pores. The diagenesis related to crack development increases the pressure- and saturation-dependent effects of samples, leading to significant decrease in the compressional wave impedance and Poisson's ratio. Dolomitization changes the properties of mineral particles, resulting in a Poisson's ratio close to dolomite. The muddy, siliceous and calcareous sediments in the low-energy environment lead to the decrease of impedance and the differential change of Poisson's ratio (significantly increased or decreased). The samples with both cracks and dissolved pores show high P-wave velocity dispersion characteristics, and the P-wave velocity dispersion of samples with only fractures or pores is the lowest.

Existing studies have primarily focused on the resources and technologies related to renewable energy. However, it is essential to investigate the influence of economic, social, and governmental actions on the spatiotemporal changes in renewable energy. This paper utilizes spatial autocorrelation analysis, fixed effects modeling, and Geographical and Time Weighted Regression (GTWR) to analyze the phased characteristics and spatial differences of renewable energy electricity, based on time series and spatial layout data of renewable energy power by province and power source type in China. Additionally, it incorporates relevant economic, demographic, and investment data to identify the driving factors behind the spatiotemporal transformations of photovoltaic (PV) and wind power, as well as the main forces promoting sustainable growth. The study reveals the presence of spatial agglomeration in China's renewable energy power generation. Moreover, a positive correlation is observed between investments in environmental protection (EPI), state-owned electric power (SPI), scientific and technological advancements (STI), and renewable energy electricity. Technological progress has reduced the dependence of renewable energy on the natural environment, facilitating its promotion and widespread adoption. These findings provide empirical support and policy guidance for the sustainable and rapid growth of China's renewable energy industry. [ABSTRACT FROM AUTHOR]

- Abstract
Federated Learning (FL) in Consumer Internet of Things (CIoT) encounters significant privacy security threats when collaborative training Machine Learning models using data distributed among numerous smart CIoT devices. This paper’s objective is to evaluate the potential privacy risks associated with FL within CIoT context, specifically through the lens of passive malicious users. We propose an evaluation scheme (MIGAN) for privacy leakage, which incorporates various privacy inference attacks. First, this paper analyzes the characteristics of privacy inference attacks in FL and summarizes privacy security threats to guide the design of the MIGAN evaluation scheme. Then, to fully utilize the privacy information in FL, this paper proposes faster model inversion and white-box membership inference. Integrating these two modules into the MIGAN framework facilitates fast and high-quality privacy data reconstruction. Finally, this paper constructs the evaluation function to measure the correlation between compromised privacy data and users’ training data. Experiments conducted on the MNIST and CelebA datasets reveal that MIGAN’s data privacy reconstruction outperforms comparable methods. Notably, MIGAN quantifies the likelihood of potential privacy leakage at 14.7% for MNIST and 8.3% for CelebA in FL with 30 clients. These results validates the practicality and relevance of MIGAN in evaluating privacy leakage risks.

- Abstract
Edge computing extends computational capabilities to the physical edge of the world, providing faster and more efficient responses to consumer devices such as smart home appliances, smartphones, and wearable devices. However, it raises a critical question: How can we efficiently manage time-sensitive and computationally intensive tasks to meet device performance needs? To address this, we propose a computational cost-driven strategy for computation offloading based on reinforcement learning for consumer devices. Firstly, we convert the problem of minimizing computational costs, including latency and energy consumption, into maximizing the cumulative rewards problem of consumer devices. Second, we design a task completion time estimation method to ensure a favorable user experience. Third, by comprehensively considering the status of the network, computational demands, and task completion times, we employ reinforcement learning techniques to determine the optimal task offload strategy for consumer devices by maximizing cumulative rewards. This ensures efficient task completion with lower computational costs. The simulation results demonstrate that our method achieves the highest rewards in different scenarios. Our method reduces the task discard ratio by 25% compared to the PPO_KLP-based offload strategy.

- Abstract
This article proposes a global sensitivity analysis method of a wireless power transfer (WPT) system in domino structure. The sensitivity of system characteristics to capacitor deviations is studied to identify sensitive parameters that cause significant uncertainty in the output. The effect of capacitor deviations on output current, power transfer efficiency, and power factor is comprehensively investigated. Interactions between capacitors are considered, and the main effect index S and the total effect index S
T are calculated by Sobol’ method. Its results indicate that the output current, power factor, and efficiency are slightly affected by the deviation of the capacitor in series with the receiving coil. Interaction between capacitors has a significant effect on the output current and power factor. Finally, the experimental setups of the three-coil and four-coil WPT systems are built. The experimental results show that when the resonant capacitor on the receiving side is varied within ±10%, the fluctuation of the output current is less than 1.5%, the maximum variation in efficiency is less than 2%, and the power factor remains almost above 0.9. The validity of the proposed global sensitivity analysis method is verified.- Published

- Abstract
Intraductal papillary neoplasm of the bile duct (IPNB) is a heterogeneous disease similar to intraductal papillary mucinous neoplasm of the pancreas. These lesions have been recognized as one of the three major precancerous lesions in the biliary tract since 2010. In 2018, Japanese and Korean pathologists reached a consensus, classifying IPNBs into type l and type 2 IPNBs. IPNBs are more prevalent in male patients in East Asia and are closely related to diseases such as cholelithiasis and schistosomiasis. From a molecular genetic perspective, IPNBs exhibit early genetic variations, and different molecular pathways may be involved in the tumorigenesis of type 1 and type 2 IPNBs. The histological subtypes of IPNBs include gastric, intestinal, pancreaticobiliary, or oncocytic subtypes, but type 1 IPNBs typically exhibit more regular and well-organized histological features than type 2 IPNBs and are more commonly found in the intrahepatic bile ducts with abundant mucin. Due to the rarity of these lesions and the absence of specific clinical and laboratory features, imaging is crucial for the preoperative diagnosis of IPNB, with local bile duct dilation and growth along the bile ducts being the main imaging features. Surgical resection remains the optimal treatment for IPNBs, but negative bile duct margins and the removal of lymph nodes in the hepatic hilum significantly improve the postoperative survival rates for patients with IPNBs.

- Abstract
Traditionally, Tripterygium hypoglaucum (Levl.) Hutch (THH) are widely used in Chinese folk to treat rheumatoid arthritis (RA). This study aimed to investigate whether the anti-RA effect of THH is related with the gut microbiota. The main components of prepared THH extract were identified by HPLC-MS. C57BL/6 mice with adjuvant-induced arthritis (AIA) were treated with THH extract by gavage for one month. THH extract significantly alleviated swollen ankle, joint cavity exudation, and articular cartilage destruction in AIA mice. The mRNA and protein levels of inflammatory mediators in muscles and plasma indicated that THH extract attenuated inflammatory responses in the joint by blocking TLR4/MyD88/MAPK signaling pathways. THH extract remarkably restored the dysbiosis of the gut microbiota in AIA mice, featuring the increases of Bifidobacterium , Akkermansia , and Lactobacillus and the decreases of Butyricimonas , Parabacteroides , and Anaeroplasma. Furthermore, the altered bacteria were closely correlated with physiological indices and drove metabolic changes of the intestinal microbiota. In addition, antibiotic-induced pseudo germ-free mice were employed to verify the role of the intestinal flora. Strikingly, THH treatment failed to ameliorate the arthritis symptoms and signaling pathways in pseudo germ-free mice, which validates the indispensable role of the intestinal flora. For the first time, we demonstrated that THH extract protects joint inflammation by manipulating the intestinal flora and regulating the TLR4/MyD88/MAPK signaling pathway. Therefore, THH extract may serve as a microbial modulator to recover RA in clincial practice.ver RA in clincial practice. [ABSTRACT FROM AUTHOR]

- Abstract
Dietary omega-3 polyunsaturated fatty acids (ω-3 PUFAs) can be classified into animal- and plant-derived ω-3 PUFAs. Patients with type 2 diabetes (T2DM) are frequently accompanied by dyslipidemia, which is closely related to the high-density lipoprotein (HDL-C) subfractions change. This study aimed to determine the effects of different sources ω-3 PUFAs on glucolipid metabolism and lipoprotein subfractions in T2DM with dyslipidemia. Ninety T2DM patients with dyslipidemia were randomly assigned to take 3 g/day fish oil (FO, containing eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)), 3 g/day perilla oil (PO, containing α-linolenic acid (ALA)), or 3 g/day blend oil (BO, containing EPA, DHA and ALA) for 3 months. 90 patients completed the intervention. There was a significant reduction of glycated hemoglobin (HbA1c) in all the groups. The triglycerides (TG) in the FO group were significantly different with a group × time interaction (P= 0.043), which was higher compared with the other two groups. The serum small HDL-C subfractions in the PO group was higher and the serum large HDL-C subfractions in the PO group was lower than those in the BO and FO groups. Plant-derived ω-3 PUFAs are more effective at controlling blood glucose than animal-derived ω-3 PUFAs. However, animal-derived ω-3 PUFAs have a significant lowering effect on TG compared with plant-derived ω-3 PUFAs. Particularly, large HDL-C subfractions after animal-derived ω-3 PUFAs intake were higher than plant-derived ω-3 PUFAs intake; while small HDL-C subfractions were lower. Both the animal- and plant-derived ω-3 PUFAs have practical value in improving glucose and lipids metabolism in T2DM patients with dyslipidemia.

- Abstract
Digital Twins (DTs) can generate digital replicas for mobile networks (MNs) that accurately reflect the state of MN. Machine learning (ML) models trained in DT for MN (DTMN) virtual environments can be more robustly implemented in MN. This can avoid the training difficulties and runtime errors caused by MN instability and multiple failures. However, when using data from various devices in the MN system, DTs must prioritize data privacy. Federated learning (FL) enables the construction of models without data leaving devices to protect DTMN data privacy. Nevertheless, FL’s privacy protection needs further improvement for it only guarantees device-level data ownership but ignores that models may retain private information from data. Therefore, this paper focuses on data forgetting in privacy protection, and proposes a novel FL-based unlearning framework (FedME2), which contains MEval and MErase modules. Guided by memory evaluation information from MEval and employing MErase’s multi-loss training approach, FedME2 gets accurate data forgetting in DTMN. In four DTMN virtual environments, FedME2 achieves an average data forgetting rate of approximately 75% for global models under FL and kept the influence on global models’ accuracy below 4%. FedME2 has better data forgetting and improves DTMN data privacy protection while guaranteeing model accuracy.

- Abstract
In recent years, researches on improving high-voltage performance of lithium-ion batteries incorporating LiNi0.5Co0.2Mn0.3O2(NCM523) and artificial graphite (AG) have been widely reported. However, limited attentions have been paid to understand the effects and influence mechanisms of charge and discharge rates and charge limit currents on cyclability of NCM523/AG cells. Herein, a ∼1.9 Ah NCM523/AG pouch cell is employed, whose electrochemical and structural evolutions after 800 cycles at various rates are comprehensively investigated. We find that cycling performances are strongly influenced by charge rate, followed by limit current and discharge rate. The cell charged at a high rate and cell charged until reaching a low limit current both exhibit low capacity retentions compared to the cell discharged at a high rate. Possible failure reasons are analyzed by advanced characterizations. Results reveal that NCM523 cathodes of the cells deteriorated early experience severe transition metal dissolution, lattice distortion, and partial phase transformation. Meanwhile, the deposited transition metals on AG anodes catalyze the electrolyte consumption, lithium plating and active area loss. Finally, these side reactions notably increase cell impedance and electrochemical polarization. Undoubtedly, these findings clearly outline the challenges and optimization direction for high-rate NCM523/AG cells.

- Abstract
Solid-state lithium batteries (SSBs) have been widely researched as next-generation energy storage technologies due to their high energy density and high safety. However, lithium dendrite growth through the solid electrolyte usually results from the catastrophic interface contact between the solid electrolyte and lithium metal. Herein, a gradient nitrogen-doping strategy by nitrogen plasma is introduced to modify the surface and subsurface of the garnet electrolyte, which not only etches the surface impurities (e.g., Li2CO3) but also generates an in situformed Li3N-rich interphase between the solid electrolyte and lithium anode. As a result, the Li/LLZTON-3/Li cells show a low interfacial resistance (3.50 Ω cm2) with a critical current density of about 0.65 mA cm–2at room temperature and 1.60 mA cm–2at 60 °C, as well as a stable cycling life for over 1300 h at 0.4 mA cm–2at room temperature. A hybrid solid-state full cell paired with a LiFePO4cathode exhibits excellent cycling durability and rate performance at room temperature. These results demonstrate a rational strategy to enable lithium utilization in SSBs.

Although radiotherapeutic efficiency has been revealed to be positively correlated with ferroptosis, the neutral/alkaline cytoplasm pH value of tumor cells remains an intrinsic challenge for efficient Fenton/Fenton-like reaction-based ferroptosis induction. Herein, PEGylated hollow mesoporous organosilica nanotheranostics (HMON)-GOx@MnO 2 nanoparticles (HGMP NPs) were designed as a ferroptosis inducer, which could specifically release Mn
2+ in tumor cells to activate the Fenton-like reaction for ferroptosis induction. Proton pump inhibitors (PPIs) were synchronously administered for cytoplasm pH level regulation by inhibiting V-H+ -ATPases activity, enhancing Fenton-like reaction-based ferroptosis induction. Moreover, reactive oxygen species production was facilitated via the glucose oxidase triggered cascade catalytic reaction by utilizing intracellular β-D-glucose for H 2 O 2 self-supply and generation of additional cytoplasm H+ . The PPI enhanced ferroptosis inducing nanosystem effectively inhibited tumor growth both in vitro and in vivo for tumor-specific ferroptosis induction and radiotherapy sensitization, suggesting that PPI administration could be an efficient adjuvant to reinforce Fenton/Fenton-like reaction-based ferroptosis induction for radiosensitization. The cytoplasm pH value of tumor cells is typically neutral to alkaline, which is higher than that of the Fenton/Fenton-like reaction desired acidic environments, hindering its efficiency. In this study, PEGylated hollow mesoporous organosilica nanotheranostics (HMON)-GOx@MnO 2 nanoparticles were synthesized as a ferroptosis inducer, which could specifically release Mn2+ via depleting glutathione and then activate the Fenton-like reaction in the tumor microenvironment. The glucose oxidase was applied for H 2 O 2 self-supply and addition of cytoplasm H+ to further boost the Fenton-like reaction. We found that proton pump inhibitors (PPIs) increased intracellular acidification by inhibiting the activity of V-H+ -ATPases to enhance the Fenton reaction-based ferroptosis induction, suggesting PPIs administration could be a feasible strategy to reinforce ferroptosis induction for radiosensitization.

- Abstract
Flexible wearable pressure sensors have received increasing attention as the potential application of flexible wearable devices in human health monitoring and artificial intelligence. However, the complex and expensive process of the conductive filler has limited its practical production and application on a large scale to a certain extent. This study presents a kind of piezoresistive sensor by sinking nonwoven fabrics (NWFs) into tungsten disulfide (WS2) and Ti3C2TxMXene solutions. With the advantages of a simple production process and practicality, it is conducive to the realization of large-scale production. The assembled flexible pressure sensor exhibits high sensitivity (45.81 kPa–1), wide detection range (0–410 kPa), fast response/recovery time (18/36 ms), and excellent stability and long-term durability (up to 5000 test cycles). Because of the high elastic modulus of MXene and the synergistic effect between WS2and MXene, the detection range and sensitivity of the piezoresistive pressure sensor are greatly improved, realizing the stable detection of human motion status in all directions. Meanwhile, its high sensitivity at low pressure allows the sensor to accurately detect weak signals such as weak airflow and wrist pulses. In addition, combining the sensor with deep-learning makes it easy to recognize human respiratory patterns with high accuracy, demonstrating its potential impact in the fields of ergonomics and low-cost flexible electronics.

- Abstract
Nowadays, wearable electronic devices are developing rapidly with the internet of things and human–computer interactions. However, there are problems such as low power, short power supply time, and difficulty in charging, leading to a limited range of practical applications. In this paper, a composite hydrogel composed of polyacrylamide, hydroxypropyl methylcellulose, and MXene (Ti3C2Tx) nanosheets was developed, which formed a stable double-chain structure by hydrogen bonding. The configuration endows the hydrogel with excellent properties, such as high strength, strong stretchability, excellent electrical conductivity, and high strain sensitivity. Based on these characteristics, a flexible multifunctional triboelectric nanogenerator (PHM–TENG) was prepared using the hydrogel as a functional electrode. The nanogenerator can collect biomechanical energy and convert it to 183 V with a maximum power density of 78.3 mW/m2. It is worth noting that PHM–TENG can be applied as a green power source for driving miniature electronics. Also, it can be used as an auto-powered strain sensor that distinguishes letters, enabling monitoring under small strain conditions. This work is anticipated to provide an avenue for the development of new intelligent systems for handwriting recognition.

- Abstract
Postprandial metabolism plays major roles in many pathological conditions. The n-6/n-3 polyunsaturated fatty acid (PUFA) ratio is closely related to various physiological disorders. This study aimed to investigate the effects of high fat meals with different n-6/n-3 PUFA ratios on postprandial metabolism in normal control (NC) and hypertriglyceridemia (HTG) rats. The postprandial response of triglyceride (TG) in HTG groups was higher than that in NC groups after different n-6/n-3 PUFA ratio meals. The HTG groups showed higher postprandial total cholesterol (TC) responses than NC groups after 1:1 and 20:1 ratio meals. The 5:1 n-6/n-3 PUFA ratio elicited lower postprandial responses of tumor necrosis factor α (TNF-α) than 1:1 and 10:1 ratios in HTG groups. The postprandial malondialdehyde (MDA) response was lower after a 5:1 n-6/n-3 PUFA ratio meal than 1:1 and 20:1 ratio meals in HTG groups. The 1:1 ratio resulted in a lower postprandial reactive oxygen species (ROS) level than 5:1 and 10:1 n-6/n-3 PUFA ratios in NC groups. The results showed that a low n-6/n-3 PUFA ratio improved postprandial dysmetabolism induced by a high fat meal in NC and HTG rats. A high n-6/n-3 PUFA ratio increased the difference in postprandial metabolism between NC and HTG rats.

- Abstract
Flexible strain sensors based on self-adhesive, high-tensile, super-sensitive conductive hydrogels have promising application in human–computer interaction and motion monitoring. Traditional strain sensors have difficulty in balancing mechanical strength, detection function, and sensitivity, which brings challenges to their practical applications. In this work, the double network hydrogel composed of polyacrylamide (PAM) and sodium alginate (SA) was prepared, and MXene and sucrose were used as conductive materials and network reinforcing materials, respectively. Sucrose can effectively enhance the mechanical performance of the hydrogels and improve the ability to withstand harsh conditions. The hydrogel strain sensor has excellent tensile properties (strain >2500%), high sensitivity with a gauge factor of 3.76 at 1400% strain, reliable repeatability, self-adhesion, and anti-freezing ability. Highly sensitive hydrogels can be assembled into motion detection sensors that can distinguish between various strong or subtle movements of the human body, such as joint flexion and throat vibration. In addition, the sensor can be applied in handwriting recognition of English letters by using the fully convolutional network (FCN) algorithm and achieved the high accuracy of 98.1% for handwriting recognition. The as-prepared hydrogel strain sensor has broad prospect in motion detection and human–machine interaction, which provides great potential application of flexible wearable devices.

- Abstract
[Display omitted] • Knockout of BnaA08.PPT1 and BnaC08.PPT1 resulted retarded growth of B. napus. • BnaPPT1 is required for membrane lipid synthesis and chloroplast development in leaves. • Overexpression of BnaC08.PPT1 significantly elevated the seed oil content. • BnaPPT1 plays an important role in maintaining plant growth and seed oil accumulation in B. napus. Phosphoenolpyruvate/phosphate translocator (PPT) transports phosphoenolpyruvate from the cytosol into the plastid for fatty acid (FA) and other metabolites biosynthesis. This study investigated PPTs' functions in plant growth and seed oil biosynthesis in oilseed crop Brassica napus. We created over-expression and mutant material of BnaPPT1. The plant development, oil content, lipids, metabolites and ultrastructure of seeds were compared to evaluate the gene function. The plastid membrane localized BnaPPT1 was found to be required for normal growth of B. napus. The plants grew slower with yellowish leaves in BnaA08.PPT1 and BnaC08.PPT1 double mutant plants. The results of chloroplast ultrastructural observation and lipid analysis show that BnaPPT1 plays an essential role in membrane lipid synthesis and chloroplast development in leaves, thereby affecting photosynthesis. Moreover, the analysis of primary metabolites and lipids in developing seeds showed that BnaPPT1 could impact seed glycolytic metabolism and lipid level. Knockout of BnaA08.PPT1 and BnaC08.PPT1 resulted in decreasing of the seed oil content by 2.2 to 9.1%, while overexpression of BnaC08.PPT1 significantly promoted the seed oil content by 2.1 to 3.3%. Our results suggest that BnaPPT1 is necessary for plant chloroplast development, and it plays an important role in maintaining plant growth and promoting seed oil accumulation in B. napus.

• A semi-supervised network integrating self-supervised adversarial learning is proposed. • Improving the performance of deep learning models on small data sets. • The proposed method can effectively diagnose subtypes of lung nodules. • Achieved the state-of-the-art results on the LIDC-IDRI dataset. Accurately diagnosing the subtype of pulmonary nodules is a crucial step in screening patients with early-stage lung cancer. However, most of existing researches can only diagnose benign and malignant pulmonary nodules but cannot give detailed subtypes. Besides, although convolutional neural networks (CNNs) have been widely used in the intelligent diagnosis of benign and malignant pulmonary nodules, it is difficult to further improve the diagnostic accuracy due to the small number of samples. In this paper, a semi-supervised network integrating self-supervised adversarial learning (SSAL-Net) suitable for small sample classification problem is proposed to diagnose adenocarcinoma, squamous cell carcinoma, inflammation, and other benign types of pulmonary nodules. SSAL-Net is mainly composed of a self-supervised classification network (SSC-Net), an unsupervised adversarial reconstruction network (UAR-Net) and a supervised classification network (SC-Net), where SSC-Net and UAR-Net share an encoder to provide representative image features to SC-Net. SSAL-Net takes three different forms of pulmonary nodule data generated based on prior knowledge as input, and enables end-to-end collaborative training through SSC-Net, UAR-Net and SC-Net performing their respective tasks. The experimental results show that SSAL-Net can identify adenocarcinoma, squamous cell carcinoma, inflammation and other benign types of pulmonary nodules with an average accuracy of 89.29% on our self-constructed lung CT image dataset, and can identify malignant pulmonary nodules with an average accuracy of 94.67% on the publicly available LIDC-IDRI dataset, obtaining the state-of-the-art results.

- Abstract
[Display omitted] • Alfalfa powder with health education significantly improves lipid profiles in dyslipidemia patients. • Reductions in total cholesterol, LDL-C, and Apo A1 levels observed with alfalfa supplementation. • Glycerophospholipid metabolism pathway identified as key to alfalfa's lipid-lowering effects. • Alfalfa supplementation shows potential as an effective intervention for managing dyslipidemia. Cardiovascular diseases (CVDs) remain the leading cause of global mortality, with dyslipidemia recognized as a significant risk factor. Dyslipidemia, characterized by elevated levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG), is associated with an increased lifetime risk of CVD. Although alfalfa's cholesterol-lowering effects have been demonstrated in animal models, clinical trial data supporting its efficacy in human dyslipidemia treatment are limited. A randomized controlled trial was conducted from September 20, 2021, to January 12, 2023, involving patients diagnosed with dyslipidemia. Approved by the China Ethics Committee of Registering Clinical Trials, the study included multiple sites in China. Eligible participants were adults aged 18 years or older, meeting criteria from the Chinese Guidelines for the Prevention and Treatment of Adult Blood Lipid Disorders. Participants were randomly assigned to either a health education-only group or a combined alfalfa powder supplementation and health education group for a three-month intervention period. A total of 160 eligible patients were enrolled and randomized into two groups: the Alfalfa group (n = 80) and the Education group (n = 80). The intervention resulted in significant improvements in key lipid parameters in the Alfalfa group, including reductions in TC, LDL-C, and Apo A1 levels. Although changes in HDL-C levels were not significantly different between the groups, the Alfalfa group exhibited a larger increase. Serum lipid metabolomics analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS) indicated that the combined intervention did not significantly alter the overall blood lipid metabolome but identified fifteen regulated differential metabolites, with the glycerophospholipid metabolism pathway significantly affecting lipid metabolism levels. Supplementation with alfalfa powder combined with health education significantly reduced TC, LDL-C, and Apo A1 levels in patients with dyslipidemia. KEGG pathway analysis suggests an association between the glycerophospholipid metabolism pathway and dyslipidemia. Further research is warranted to validate these findings and explore the underlying mechanisms. [ABSTRACT FROM AUTHOR]

- Abstract
• ESG rating divergence significantly increases audit fees due to information asymmetry. • External factors like internationalisation and low-carbon initiatives moderate this effect. • Analysis highlights the importance of standardising ESG evaluations for policymakers. We investigate the impact of ESG (Environmental, Social, and Governance) rating discrepancies on audit fees using data from A-share companies listed in Shanghai and Shenzhen from 2015 to 2022. We find that ESG rating divergence significantly increases audit fees due to increased information asymmetry, heightened operational risks, and elevated debt costs. External factors like internationalisation and participation in low-carbon initiatives moderate this relationship. Our results, which remain robust to alternative measures and endogeneity checks, provide valuable insights into how ESG performance can influence audit fees and highlight the importance of standardising ESG evaluations for both firms and policymakers.

- Abstract
Due to high volumetric energy density, the major market share of cathode materials for lithium-ion batteries is still dominated by LiCoO2(LCO) at a 3C field. However, a number of challenges will be triggered if the charge voltage is increased from 4.2/4.3 to 4.6 V to further increase energy density, such as a violent interface reaction, Co dissolution, and release of lattice oxygen. Here, LCO is coated with the fast ionic conductor Li1.8Sc0.8Ti1.2(PO4)3(LSTP) to form LCO@LSTP, while a stable interface of LCO is in situconstructed by the decomposition of LSTP at the LSTP/LCO interface. As decomposition products of LSTP, Ti and Sc elements can be doped into LCO and thus reconstruct the interface from a layered structure to a spinel structure, which improves the stability of the interface. Moreover, Li3PO4from the decomposition of LSTP and remaining LSTP coating as a fast ionic conductor can improve Li+transport when compared with bare LCO, and thus boost the specific capacity to 185.3 mAh g–1at 1C. Benefited from the stable interface and fast ion conducting coating, the LCO@LSTP (1 wt %) cathode delivers a high capacity of 202.3 mAh g–1at the first cycle (0.5C, 3.0–4.6 V), and shows a higher capacity retention of 89.0% than LCO (50.9%) after 100 cycles. Furthermore, the change of the Fermi level obtained by using a kelvin probe force microscope (KPFM) and the oxygen band structure calculated by using density functional theory further illustrate that LSTP supports the performance of LCO. We anticipate that this study can improve the conversion efficiency of energy-storage devices.

- Abstract
Pulmonary epithelial barrier injury contributes to acute lung injury, accelerating exudate formation, and resulting alveolar edema. Heme oxygenase-1 (HO-1) plays an important role in ameliorating the pathological symptoms of acute lung injury (ALI). Using an ALI mouse model induced by LPS inhalation, the present study explored the potential molecular regulatory effect of hemin (a potent HO-1 inducer) against ALI epithelial damage. Lipopolysaccharide challenge triggered dysfunction of the alveolar epithelial barrier, impaired tight junctions, and disrupted alveoli fluid clearance, while these pathological changes were effectively reversed by hemin treatment. Furthermore, HO-1 elevation inhibited the activation of the nucleotide-binding domain-like receptor protein 3 (NLRP3) inflammasome and oxidative stress in alveolar epithelia, leading to the suppression of inflammatory responses and epithelial pyroptosis, as indicated by the decreased levels of NLRP3 and apoptosis-associated speck-like protein containing a CARD domain (ASC), repressed cleavage of caspase-1 and gasdermin D, and reduced expression levels of inflammatory cytokine IL-1β. In contrast, protoporphyrin IX zinc (II) (ZnPP, an HO-1 inhibitor) treatment had no protective effect on LPS inhalation-induced ALI in mice. In summary, HO-1 induction serves a critical role in maintaining airway epithelium homeostasis through the inhibition of NLRP3/ASC/caspase-1–mediated pyroptosis and inflammation in the occurrence of ALI.

- Abstract
Population aging is a global problem worldwide, and the discovery of antiaging drugs and knowledge of their potential molecular mechanisms are research hotspots in biomedical field. Tetrahydroxystilbene glucoside (TSG) is a natural component isolated from Heshouwu (Polygonum multiflorumThunb.). It has been widely used to treat various chronic diseases for its remarkable biological activities. In this study, we successfully established aging larval zebrafish by exposing larvae to 2 mM hydrogen peroxide (H2O2). Using this aging model, we assessed the antiaging effect of TSG with different concentrations (25–100 μg/mL). After being treated with H2O2, zebrafish showed the obvious aging-associated phenotypes characterized by higher senescence-associated β-galactosidase activity, significantly downregulated expression of sirtuin 1 (sirt1) and telomerase reverse transcriptase (tert), and upregulated serpine1mRNA level compared to the control group. TSG pretreatment delayed the aging process of oxidative stress-induced zebrafish, indicative of the reduced positive rate of senescence-associated β-galactosidase, improved swimming velocity, and stimulus-response capacity. Further studies proved that TSG could suppress reactive oxygen species production and enhance the activity of antioxidant enzymes superoxide dismutase and catalase. TSG also inhibited the H2O2-induced expressions of inflammation-related genes il-1β, il-6, cxcl-c1c, and il-8in aging zebrafish, but it did not affect apoptosis-related genes (bcl-2, bax, and caspase-3) of aging zebrafish. In conclusion, TSG can protect against aging by regulating the antioxidative genes and enzyme activity, as well as inflammation in larval zebrafish, providing insight into the application of TSG for clinical treatment of aging or aging-related diseases.
