Inflammatory factors may play an important role in the occurrence and development of schizophrenia.ObjectiveTo explore the relationship of the inflammatory factor levels with metabolic levels， language fluency and information processing function in patients with schizophrenia， so as to provide references for clinical understanding of the neuropathological mechanisms of schizophrenia.MethodsA total of 96 patients with schizophrenia were included in the study group， who were hospitalized in the Fourth People's Hospital of Hefei from January 2021 to December 2022 as well as met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） and Mini-International Neuropsychiatric Interview （MINI） 6.0 .Meanwhile， population who underwent physical examination at the same hospital were included in the control group （n=42）. A high-sensitivity multi factor electrochemiluminescence analyzer was used to detect the levels of inflammatory factors IL-4， IL-5， IL-7， IL-8， IL-10 and IL-13. A fully automated biochemical analyzer was used to detect the levels of metabolic indicators such as fasting blood glucose， triglycerides， high-density lipoprotein， apolipoprotein A， creatinine and urea nitrogen. Verbal fluency and information processing function of all participants were assessed by using Verbal Fluency Test （VFT） and Stroop Color Word Test （SCWT）.ResultsThere were statistically significant differences in the levels of IL-4， IL-5， IL-7， IL-8， IL-10， IL-13 and IL-15 between the study group and the control group （P

Abstract Few‐shot learning enables machines to learn efficiently from limited labelled data. However, existing few‐shot learning methods may perform poorly when there is a lack of sufficient samples, and may encounter problems such as domain shift or overfitting when applied to new domains or tasks. To address the issues of poor fitting and insufficient generalization ability in new domains, a new method called triplet merged network with involution operators (TMNIO) is proposed. This method employs dual encoders that extract common and distinctive features from the prototype network, thereby enhancing the model's feature extraction capability. To further improve this ability, the traditional convolutional kernels are replaced with involution operators, which not only reduce the parameter count but also enlarge the receptive field to better extract local feature information. Additionally, this method employs a two‐stage training strategy, where triplet loss is used in the first stage to train the model and enhance its robustness and generalization ability. Extensive experiments on the miniImageNet, Omniglot, and Caltech‐UCSD Birds‐200 (CUB) datasets have shown that our proposed method achieved significant improvements in both training speed and accuracy, particularly on the miniImageNet dataset, where it achieved an outstanding 10% performance improvement.

旨在为酶法和化学法抗坏血酸棕榈酸酯(L-AP)在植物油中的应用提供参考，并为家庭储存植物油的方法提供建议，以酸值和过氧化值为指标，模拟家庭储存条件，分别考察低温（20 ℃）避光、常温（25 ℃）曝光、高温（60 ℃）避光，满瓶或半瓶等条件下两种L-AP对菜籽油的抗氧化效果，并与叔丁基对苯二酚（TBHQ）、维生素E（VE）和脂溶性茶多酚等抗氧化剂进行比较，采用Rancimat法测定添加不同抗氧化剂的菜籽油、大豆油、棕榈油和亚麻籽油的氧化诱导时间。结果表明:酶法L-AP和化学法L-AP对植物油的抗氧化作用相似，且抗氧化能力与脂溶性茶多酚相当，强于VE。植物油在低温（20 ℃）避光、满瓶条件下储存，其酸值、过氧化值随时间变化最小。综上，酶法L-AP和化学法L-AP均可有效延缓植物油氧化，推荐消费者优先选用添加有符合国标的抗氧化剂的小包装植物油产品，并储存于低温避光的环境中。In order to provide references for the application of enzymatic and chemical L-ascorbyl palmitate (L-AP) in edible vegetable oil and provide suggestions for the home storage of vegetable oil, with acid value and peroxide value as indexes, the antioxidant effects of L-AP on rapeseed oil stored under simulated home storage conditions of low temperature (20 ℃) and away from light, room temperature (25 ℃) exposure, and high temperature (60 ℃) and away from light, and full or half bottles were investigated, and was compared with TBHQ, VE, and fat-soluble tea polyphenols. The Rancimat method was used to identify the oxidation induction time of rapeseed oil, soybean oil, palm oil, and flaxseed oil added with various antioxidants. The results showed that both the antioxidant effects of the two L-AP on vegetable oil were similar, and was similar to that of fat-soluble tea polyphenols, stronger than VE. The acid value and peroxide value of vegetable oil had the smallest changes over time when it was stored at at low temperature (20 ℃), away from light and full bottle conditions. In conclusion, enzymatic and chemical L-AP can effectively inhibit the oxidation of vegetable oil. Meanwhile, it is suggested that consumers prioritize using small bottled vegetable oil products with antioxidants that meet national standards and store them in a low temperature and away from light environment.

The N-doped carbon nanofiber coated graphene nanosheets (NFGNs) were designed and constructed using EGNs as the skeleton and PPy as the carbon source. The samples were characterized by SEM, XRD, Raman, FTIR, XPS and BET. The results show that the interconnected N-doped carbon nanofibers are uniformly coated on the surface of EGNs. The NFGNs-800 presents high-level nitrogen atom doping of 11.53% and large specific surface area of 477.65 m2·g-1. The capacitance performance test results show that the NFGNs-800 electrode material exhibits high specific capacitance of 323.3 F·g-1 (1.0 A·g-1) and good rate characteristic. NFGNs-800 supercapacitor shows high energy density of 87.1 Wh·kg-1 at power density of 10500 W·kg-1. The specific capacitance of the supercapacitor is 95.9% of the initial specific capacitance and the columbic efficiency still remains above 99% after 10000 constant current charge discharge cycles.

The exact nature and derivation of patient-subject constructions (PSC) in Chinese are still at dispute in literature. Based on the restriction of manner adverbial modification and the nonexistence of the manner reading of zenme ‘how’ observed in Chinese PSC, a morphosyntactic analysis has been provided. We argue that the seeming action verb V in PSC is not a real main verb, but a verbal root to be introduced into the derivation after syntax via external morphological merger. The real main verb of PSC in syntax is a covert light verb ∅BEC, which selects a nominal phrase (NP) as its specifier (Spec) and a resultative phrase (RP) as its complement. BECP is further selected by an aspect (Asp) head le. To satisfy the extended projection principle (EPP), the NP at [Spec, BECP] moves to the [Spec, TP] in syntax. After syntax, the resultative (R) head-moves to ∅BEC at the phonological form (PF) to satisfy the phonological requirement of ∅BEC, forming R-∅BEC; then, a bare verbal root merges with R-∅BEC at PF to denote the manner of the change of state. Due to the phonological requirement of le, V-R-∅BEC head-moves to le, producing the right order of PSC. The two elided forms of PSC can be derived similarly. This research suggests that covert light verbs and morphology may play an interactive role in the derivation of some “typical” constructions in Chinese.

Natural gas hydrates gradually become the focus of new energy resources, and the study of hydrate exploitation is growing vigorously during recent years. Well cementing is an important process during energy exploitation, especially when encounters hydrate bearing sediments in deep-water oil and gas drilling, showing great research significance and becoming a research hotspot. In this study, the exploratory well of SH2 of GMGS-1 project is chosen as the object of study, a cementing model of two dimensions based on this exploratory well is build, the invasion process of cement slurry is reappeared by TOUGH+HYDRATE, and the physical properties response of hydrate reservoirs during the cementing process is analyzed based on the numerical simulation data. In which, a view of “continuous stage simulation” to solve the problem of dynamic heat release of cement slurry is created and used for the first time. Result illustrated that the invasion behavior of cement slurry almost only occurred during the stage of holding pressure, the temperature has significantly increased in the area of reservoir which is invaded by cement slurry. At the same time, a large amount of decomposed hydrate have generated gas and water, which form high pressure region and transfer toward the deeper of reservoir. However, the variation in the temperature is not significant and the hydrate barely no longer decomposed in those area which outside or even though close to this area. There also have generated secondary hydrate closed to the area of decomposition and formed high saturation zone of hydrate. The results also proved the feasibility of “continuous stage simulation”, and played a guiding significance for the field well cementing.

The new energy represented by strong random wind power connecting to the power system may make the problem of inter-area low-frequency oscillation more serious. In this paper, a DFIG-PSS controller based on virtual impedance is constructed to solve the low-frequency oscillation problem in the wind power system. The step response of PSS-VI was carried out to test the effect of the controller to verify the advantages of PSS-VI than traditional PSS. The input signal of PSS-VI which is a controller based on PSS installed virtual impedance is the active power of DFIG. The output signal of PSS-VI is added to the reactive power control loop of rotor side controller of DFIG. DFIG-PSS-VI was built in Digsilent/Powerfactory software, and the simulation was carried out on the system of 4 machines and 2 regions. It is verified that PSS-VI can improve the low-frequency oscillation of wind power system.
