Research on the Deposit Insurance Pricing Under the Marketing RMB Interest Rate

The deposit insurance pricing is the core issue of deposit insurance system, it determines the success or failure of the deposit insurance system in a way. In the current deposit insurance pricing methods, we treat the interest rates as a constant. With the interest rate marketization in China, the deposit insurance pricing methods have also changed accordingly. In this paper, we will give a functional representation of the impact of RMB interest rate marketization on interest rate by fitting the coefficients of the cubic function. Then we will use the data of 2013 to prove it. For the points that do not conform to this rule, we also have some explanations related to the major economic events at that time

Superior cervical ganglionectomy alters gut microbiota in rats

The diversity and complexity of sympathetic function highlight the importance of fundamental research. Little is known about the interaction of superior cervical sympathetic ganglion (SCG) and gut microbiota. In this study, the engagement of the sympathetic ganglia with gut microbiota was investigated. Bilateral superior cervical ganglionectomy (SCGx) significantly altered the microbiota composition in rats 14 days post-surgery, and these microbiotas may participate in several biological pathways in the host, suggesting the vital role of the cervical sympathetic ganglion in regulating the microbiome-brain axis, and further confirming that the sympathetic nervous system (SNS) regulates the microbiome-brain axis

The role of gut microbiota in chronic restraint stress-induced cognitive deficits in mice

Background: Chronic stress induces cognitive deficits. There is a well-established connection between the enteric and central nervous systems through the microbiota-gut-brain (MGB) axis. However, the effects of the gut microbiota on cognitive deficits remain unclear. The present study aimed to elucidate the microbiota composition in cognitive deficits and explore its potential in predicting chronic stress-induced cognitive deficits. Methods: Mice were randomly divided into control and chronic restraint stress (CRS) groups. The mice subjected to CRS were further divided into cognitive deficit (CRS-CD) and non-cognitive deficit (CRS-NCD) groups using hierarchical cluster analysis of novel object recognition test results. The composition and diversity of the gut microbiota were analyzed. Results: After being subjected to chronic restraint distress, the CRS-CD mice travelled shorter movement distances (p = 0.034 vs. CRS-NCD; p < 0.001 vs. control) and had a lower recognition index than the CRS-NCD (p < 0.0001 vs. CRS-NCD; p < 0.0001 vs. control) and control mice. The results revealed that 5 gut bacteria at genus levels were significantly different in the fecal samples of mice in the three groups. Further analyses demonstrated that Muricomes were not only significantly enriched in the CRS-CD group but also correlated with a decreased cognitive index. The area under the receiver operating curve of Muricomes for CRS-induced cognitive deficits was 0.96. Conclusions: Our study indicates that the composition of the gut microbiota is involved in the development of cognitive deficits induced by chronic restraint stress. Further analysis revealed that Muricomes have the potential to predict the development of chronic stress-induced cognitive deficits in mice. Keywords: Gut microbiota, Chronic restraint stress, Cognitive deficits, Muricomes Mic

V-NetLab: A Cost-Effective Platform to Support Course Projects in Computer Security

Network and computer courses need dedicated laboratories for students to carry out hands-on assignments and course projects. Typically, these projects require each student to be given administrative access to an entire, isolated network of computers. The obvious approach of creating one dedicated physical network for each student is prohibitively expensive, both in terms of hardware costs, as well as the management overhead in setting up and administering these networks. We have therefore developed a platform where logically isolated virtual networks of computers can be set up very easily. The platform greatly simplifies administration of virtual networks by automating the startup and shutdown of these networks. In addition, our platform simplifies customization of the configurations of di#erent computers on a virtual network, and moreover, provides features to permute these configurations across di#erent student groups. A novelty of our approach is that these networks are realized on a modest size physical networks consisting of commodity PCs. In our experiments to date, classes of 50 students have been supported with a hardware platform costing under $30K, where each student has access to a dedicated, logical network of 6 to 8 (virtual) computers

Photoelectrochemical Complexes of Fucoxanthin-Chlorophyll Protein for Bio-Photovoltaic Conversion with a High Open-Circuit Photovoltage

Open-circuit photovoltage (V-oc) is among the critical parameters for achieving an efficient light-to-charge conversion in existing solar photovoltaic devices. Natural photosynthesis exploits light-harvesting chlorophyll (Chl) protein complexes to transfer sunlight energy efficiently. We describe the exploitation of photosynthetic fucoxanthin-chlorophyll protein (FCP) complexes for realizing photoelectrochemical cells with a high V-oc. An antenna-dependent photocurrent response and a V-oc up to 0.72V are observed and demonstrated in the bio-photovoltaic devices fabricated with photosynthetic FCP complexes and TiO2 nanostructures. Such high V-oc is determined by fucoxanthin in FCP complexes, and is rarely found in photoelectrochemical cells with other natural light-harvesting antenna. We think that the FCP-based bio-photovoltaic conversion will provide an opportunity to fabricate environmental benign photoelectrochemical cells with high V-oc, and also help improve the understanding of the essential physics behind the light-to-charge conversion in photosynthetic complexes

Data_Sheet_1_Gut microbiota-generated short-chain fatty acids are involved in para-chlorophenylalanine-induced cognitive disorders.ZIP

Neurocognitive disorders (NCDs) include complex and multifactorial diseases that affect many patients. The 5-hydroxytryptamine (5-HT) neuron system plays an important role in NCDs. Existing studies have reported that para-chlorophenylalanine (PCPA), a 5-HT scavenger, has a negative effect on cognitive function. However, we believe that PCPA may result in NCDs through other pathways. To explore this possibility, behavioral tests were performed to evaluate the cognitive function of PCPA-treated mice, suggesting the appearance of cognitive dysfunction and depression-like behavior. Furthermore, 16S rRNA and metabolomic analyses revealed that dysbiosis and acetate alternation could be related to PCPA-induced NCDs. Our results suggest that not only 5-HT depletion but also dysbiosis and acetate alternation contributed to PCPA-related NCDs. Specifically, the latter promotes NCDs by reducing short-chain fatty acid levels. Together, these findings provide an alternative perspective on PCPA-induced NCDs.</p

Research on Range of Appropriate Spatial Scale of Underground Commercial Street Based on Psychological Perception Evaluation

Developing and utilizing underground space is a vital direction for urban growth. Underground commercial streets, as a significant component of underground space accommodating extensive human social activities, consequently necessitate the creation of human-scale spaces. In the evolution of urban design development towards more significant, more terrific refinement, applying architectural theories and excessively subjective designs has resulted in a deficient human-centered design and a disordered spatial environment. This study merges environmental psychology and architectural theory to determine the appropriate length of spatial scale. Two experiments focusing on spatial perception evaluation were conducted using a virtual experimental platform that featured varying dimensions of spatial scale combinations. These quantified combinations were correlated with the perception evaluation, and a regression analysis was employed to identify appropriate scale ranges, which were superimposed with the range of length selection. Finally, the optimal length and scale combination for underground commercial street spaces was established, providing a reference for the human-centered design of these environments
