Abstract	Hongqi sag is located in the north of Beiehur depression in Hailar Basin, which is a secondary structural unit in the peripheral depression of Hailar Basin, with great exploration potential. Based on SEM, conventional thin sheet, cast thin sheet, mercury pressure and physical property data, this paper discusses the reservoir characteristics, types and control factors of high quality reservoir in Tongbomiao formation, Hongqi sag, so as to provide a strong geological basis for the exploration of oil and gas in this area. The reservoir space of Hongqi sag is mainly composed of four types: primary intergranular pore, micro fracture, feldspar dissolution pore and debris dissolution pore. It is of the type of ultra low porosity and low permeability. Although Tongbomiao formation in Hongqi sag is of very low porosity and low permeability type, high quality reservoir is still developed, and its reason is mainly controlled by sedimentary environment, diagenesis and structural fracture.

Abstract	Carbon is the fundamental element of plant life. Non-structural carbohydrates (NSC), synthesized using carbon dioxide through photosynthesis by plants, are essential for their growth and survival, which are also affected by light and temperature. However, few studies have investigated the effects of light conditions, season, and needle age together on field plants’ carbohydrates. We measured total carbon, glucose, sucrose, fructose, and starch concentrations in current and 1-year-old needles of Korean pine ( Pinus koraiensis Sieb. et Zucc) growing under two distinct light conditions (dense canopy and full light) from early summer to cold winter. Total carbon, glucose, fructose, SS (soluble sugar, sucrose + glucose + fructose), NSC (soluble sugar + starch), starch, and SS/NSC all significantly ( p < 0.05) related to the DOY (day of the year, 2021). Total carbon reached the maximum in September when the fresh needles were mature. Glucose, NSC, SS, and SS/NSC reached the maximum at the last sampling time, which provided protection for the cells in cold winter. The season showed a bigger impact on total carbon and NSC (all parameters except total carbon) than light and needle age. Two different-aged needles under two light conditions all had similar patterns of variation in total carbon and NSC, but twigs showed a more significant ( p < 0.05) difference in NSC concentrations between two light conditions on 25 October (DOY 249). Needles of Korean pines stored soluble sugars (mainly glucose) and consumed starch in winter. Moreover, we found that needles had more glucose, while twigs had more sucrose, which may be a result of their different functions and may be helpful for future spring growth. Although lacking light during the growing season, understory Korean pines still had enough cold tolerance, similar to full-light ones, which indicated that low light during the growing season has little effect on cold tolerance.

Abstract	Abstract Resistivity low-contrast oil pays are a kind of unconventional oil resource with no obvious difference in physical and electrical properties from water layers, which makes it difficult to be identified based on the characteristics of the geophysical well logging response. In this study, the support vector machine (SVM) technology was used to interpret the resistivity low-contrast oil pays in Chang 8 tight sandstone reservoir of Huanxian area, Ordos Basin. First, the input data sequences of logging curves were selected by analyzing the relationship between reservoir fluid types and logging data. Then, the SVM classification model for fluid identification and SVR regression model for reservoir parameter prediction were constructed. Finally, these two models were applied to interpret the resistivity low-contrast oil pays in the study area. The application results show that the fluid recognition accuracy of the SVM classification model is higher than that of the logging cross plot method, back propagation neural network method and radial basis function neural network method. The calculation accuracy of permeability and water saturation predicted by the SVR regression model is higher than that based on the experimental fitting model, which indicates that it is feasible to carry out logging interpretation and evaluation of the resistivity low-contrast oil pays by the SVM method. The research results not only provide an important reference and basis for the review of old wells but also provide technical support for the exploration and development of new strata.

Abstract	Based on the comprehensive analysis of wellbore characteristics in a deep shale gas field, the in-situ stress state of the shale reservoir was assessed in this study for the Longmaxi formation in the Dingshan area, Southwestern China. The data obtained from hydraulic fracturing, drilling-induced fractures, and in-situ core testing were used to determine the magnitude and direction of the maximum principal horizontal stress in five wells. Besides, hydraulic fracturing and cross-multipole array acoustic logging (XMAC) were employed to determine the vertical variation of the in-situ stress. Based on the logging interpretation and mechanical test results, the spatial distribution of rock mechanical parameters in the Dingshan area was assessed by the amplitude variation versus offset (AVO) seismic inversion. A 3D heterogeneous mechanical inversion model was realized via the ANSYS and CATIA3D finite element software packages, providing the area in-situ stress field simulation. The depth, fault strike, and position change effects on the main stress, horizontal stress difference, and horizontal stress difference coefficient were numerically simulated. The results show that the maximum principal stress azimuth was mainly concentrated in the NE20°-NE80° sector. Moreover, the development zone of natural fractures was related to the area with the highest principal stress differences. The maximum principal stress variation in the study area was mainly in the compressive range from −135 to −45 MPa, gradually increasing from east to west and south to north. The stress type mainly depended on the depth, fault strike, and rock mechanical parameters, while the stress difference and stress difference coefficient near the fault structure were relatively small. This study’s findings are considered instrumental in improving the borehole stability, determining the casing setting point, and optimizing the well location in deep shale reservoirs with similar geological conditions.

Abstract	Avian influenza viruses (AIVs) have caused a large number of epidemics in domestic and wild birds, and even posed a health challenge to humans. Highly pathogenic AIVs have attracted the most public attention. However, low pathogenic AIVs, including H4, H6, and H10 subtype AIVs, have spread covertly in domestic poultry, without obvious clinical signs. The emergence of human infections with H6 and H10 AIVs and the evidence of seropositivity of H4 AIV in poultry-exposed individuals indicated that these AIVs sporadically infect humans and could cause a potential pandemic. Therefore, a rapid and sensitive diagnostic method to simultaneously detect Eurasian lineage H4, H6, and H10 subtype AIVs is urgently required. Four singleplex real-time RT-PCR (RRT-PCR) assays were established based on carefully designed primers and probes of the conserved regions of the matrix, H4, H6, and H10 genes and combined into a multiplex RRT-PCR method to simultaneously detect H4, H6, and H10 AIVs in one reaction. The detection limit of the multiplex RRT-PCR method was 1–10 copies per reaction when detecting standard plasmids, and showed no cross-reaction against other subtype AIVs and other common avian viruses. Additionally, this method was suitable to detect the AIVs in samples from different sources, the results of which showed high consistency with virus isolation and a commercial influenza detection kit. In summary, this rapid, convenient, and practical multiplex RRT-PCR method could be applied in laboratory testing and clinical screening to detect AIVs.

Abstract	Background Influenza is an acute infectious respiratory disease caused by the influenza virus that seriously damages human health, and the essential way to prevent influenza is the influenza vaccine. Vaccines without adjuvants produce insufficient specific antibodies and therefore require adjuvants to boost antibody titers. Microbes and hosts are a community that needs to “promote bacteria,” which could provide new value for the immune effect. Methods (1) The H1N1 influenza vaccine, in combination with Ginsenoside Rb1, was co-injected into mice intraperitoneally (I.P.). Then, immunoglobulin G and antibody subtype levels were tested by enzyme-linked immunosorbent assay (ELISA). Moreover, mice were infected with a lethal dose of the H1N1 influenza virus (A/Michigan/45/2015), and survival status was recorded for 14 days. Lung tissues were stained by hematoxylin and eosin (H&E), and ELISA detected inflammatory factor expression levels. (2) Mice were immunized with Ginsenoside Rb1 combined with quadrivalent influenza inactivated vaccine(IIV4), and then IgG levels were measured by ELISA. (3) Fresh stool was collected for fecal 16S rDNA analysis. Results Ginsenoside Rb1 boosted IgG and antibody subtypes in the H1N1 influenza vaccine, improved survival of mice after virus challenge, attenuated lung histopathological damage, and reduced inflammatory cytokines expression in IL-6 and TNF-α. The results of 16S rDNA showed that Rb1 decreased species diversity but increased species richness compared to the PBS group and increased the abundance of Akkermansiaceae and Murbaculaceae at the Family and Genus levels compared with the HA+Alum group. Conclusion Ginsenoside Rb1 has a boosting effect on the immune efficacy of the H1N1 influenza vaccine and is promising as a novel adjuvant to regulate the microecological balance and achieve an anti-infective effect.

Abstract	A combined cold and power system integrated SOFC, sSCO₂ power cycle, and compression–absorption refrigeration (CAR) is designed and optimized to utilize the high-temperature waste heat of solid oxide fuel cell (SOFC). On the premise of retaining the preheating capacity, the waste heat of the gas from after burner is first used to drive the sCO₂ power cycle. The inlet temperature of compressor in sCO₂ power cycle is appropriately raised to avoid the pinch point. The residual heat of sCO₂ is used to drive CAR with [Na(Tx-7)]SCN/NH₃ as working fluid. On the basis of the electrochemical reaction model of SOFC and the first and second laws of thermodynamics, the steady state characteristics are simulated by using the engineering equation solver. The reliability and energy balance of the model is verified. The optimizations, comparison, and exergy analysis are conducted and discussed. The optimal nCH₄, TFC,ᵢₙ, and γSC are determined to be 0.004136 mol/s, 1029.1 K, and 2.5, respectively. The circulation ratio should be controlled within the range of 3.9 to 4.0. Comparison results reveal the exergy efficiency of the proposed system is higher than that of the SOFC/GT-ORC system by at least 0.035. The main reason for exergy destruction is due to the chemical reactions. The exergy destruction of the SOFC subsystem is the largest, which accounts for 73.7% of the total exergy destruction.
