Improved Dynamic Subjective Logic Model with Evidence Driven

( Jiao Hong Qiang ),( Wang Xin Xin ),( Tian Jun Feng ) 한국정보처리학회 2015 Journal of information processing systems Vol.11 No.4

In JØsang’s subjective logic, the fusion operator is not able to fuse three or more opinions at a time and it cannot consider the effect of time factors on fusion. Also, the base rate (a) and non-informative prior weight (C) could not change dynamically. In this paper, we propose an Improved Subjective Logic Model with Evidence Driven (ISLM-ED) that expands and enriches the subjective logic theory. It includes the multi-agent unified fusion operator and the dynamic function for the base rate (a) and the non-informative prior weight (C) through the changes in evidence. The multi-agent unified fusion operator not only meets the commutative and associative law but is also consistent with the researchers’s cognitive rules. A strict mathematical proof was given by this paper. Finally, through the simulation experiments, the results show that the ISLM-ED is more reasonable and effective and that it can be better adapted to the changing environment.

As we all know, there is a close relationship between Japanese and Chinese. Therefore, there are many related researches. Based on the research of seniors, I intend to re-explain the correspondence between Japanese pronunciation and different pronunciations in Japanese and Chinese from the perspective of phonology and acoustics. Both Japanese and Chinese are the voices developed on the basis of ancient Chinese in ancient times. Although Japanese has experienced many developments and changes for a long time, Chinese is the root of Japanese, and the two languages still have voice. Multiple connections. This thesis will focus on the 272-word polyphonic words in Japanese pronunciation, and explain the relationship between Japanese and Chinese characters from the Japanese and Chinese syllables, Japanese consonants and Chinese consonants, Japanese vowels and vowels. Correspondence relationship. The correspondence relationship mainly explains the development process of Chinese Pinyin in different historical periods and the correspondence between Japanese Wuyin, Hanyin, Tang and Song Dynasties, and idioms. The main purpose of writing this paper is to discuss the subtle relationship between Japanese and Chinese speech, find out the corresponding relationship, and discuss the reasons for formation as much as possible.

( Meng Jiao Cui ),( Xin Wei ),( Peng Liang Xia ),( Ji Ping Yi ),( Zhi He Yu ),( Jian Xin Deng ),( Qi Li Li ) 한국균학회 2021 Mycobiology Vol.49 No.3

Two Diaporthe species isolated from fruit of Citrus sinensis in China were characterized based on morphology and multilocus phylogeny of ITS, tef1, and tub2 gene sequences. The phylogeny indicated that the two species match Diaporthe taoicola and D. siamensis. A critical examination of phenotypic characteristics confirmed the phylogenetic results. Diaporthe taoicola was morphologically characterized by producing Alpha conidia with tapering toward both ends. Meanwhile, D. siamensis produced cylindrical or ellipsoidal Alpha conidia with two oil drops. Pathogenicity tests revealed that both species were pathogenic to fruit of C. sinensis. To our knowledge, the two species were firstly reported on Citrus sinensis in China.

Background/Aims Increasing evidence shows involvement of psychological disorders in functional dyspepsia (FD), but how psychological factors exert their influences upon FD remains largely unclear. The purpose of the present study was to explore the brain-based correlations of psychological factors and FD. Methods Based on Fluorine-18-deoxyglucose positron emission tomography-computed tomography, the altered cerebral glycometabolism was investigated in 40 FD patients compared with 20 healthy controls during resting state using statistical parametric mapping software. Results FD patients exhibited increased glucose metabolism in multiple regions relative to controls (P < 0.001, family-wise error corrected). After controlling for the dyspeptic symptoms, increased aberrations persisted within the insula, anterior cingulate cortex (ACC), middle cingulate cortex (MCC) and middle frontal cortex (midFC), which was related to anxiety and depression score. Interestingly, FD patients without anxiety/depression symptoms also showed increased glycometabolism within the insula, ACC, MCC and midFC. Moreover, FD patients with anxiety/depression symptoms exhibited more significant hypermetabolism within the above 4 sites compared with patients without anxiety/depression symptoms.Conclusions Our results suggested that the altered cerebral glycometabolism may be in a vicious cycle of psychological vulnerabilities and increased gastrointestinal symptoms.

Jiao He,Xin Zhang,Jingbao Lian,Xue Zhang 한양대학교 청정에너지연구소 2024 Journal of Ceramic Processing Research Vol.25 No.1

The transparent Y2O3 ceramic was prepared in this work via vacuum sintering of Y2O3 nanopowder obtained by sulfuric acidassistedcalcination. The calcination temperature notably influenced the dispersion, morphology and sinterability of Y2O3nanopowders. The calcined powders at various temperatures showed similar shapes, primarily comprised of round particleswith an isotropic surface. Nevertheless, the particle size gradually increased as the calcination temperature was raised. Thepowder calcined at 1100 ℃ showed a lower agglomerate state (n = 2.19) and better sintering properties instead of thoseobtained at other calcination temperatures, which can be correlated with a larger specific surface area at the low temperatureof <1100 ℃ and the rapid growth of large particles at 1200 ℃, respectively. The powder, calcined at 1100 ℃ was vacuumsintered in transparent ceramics for 5 h at a temperature of 1700 ℃. The transparent ceramic exhibited a dense and uniformmicrostructure, and the 1.5 mm thick sample has an inline transmission of up to 70% at 800 nm wavelength

Two facultatively anaerobic, short rod-shaped, non-motile, Gram-stain-positive, unknown bacterial strains (JY-X040T and JY-X174) were isolated from fluvial sediments of Tongtian River in Yushu Tibetan Autonomous Prefecture, Qinghai province, China. Cells formed translucent, gray, round and convex colonies, with a diameter of less than 0.5 mm after 5 days of incubation at 30°C on brain heart infusion-5% sheep blood agar. The 16S rRNA gene sequence similarity between strain JY-X040T and Fudania jinshanensis 313T is 93.87%. In the four phylogenetic trees constructed based on the 16S rRNA gene and 423 core genes, the two isolates form an independent branch, phylogenetically closest to F. jinshanensis 313T, but could not be classified as a member of the genus Fudania or any other genus of the family Arcanobacteriaceae. The DNA G + C content of strain JY-X040T was 57.8%. Calculation results of average nucleotide identity, digital DNADNA hybridization value and amino acid identity between strain JY-X040T and F. jinshanensis 313T are 69.9%, 22.9%, and 64.1%. The major cellular fatty acids were C16:0 (23%) and C18:1ω9c (22%). The cell-wall peptidoglycan type was A5α (L-Lys-L-Ala-L-Lys-D-Glu). The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and four unidentified components. The whole-cell sugars contained rhamnose and ribose. MK-10(H4) was the sole respiratory quinone. The minimum inhibitory concentration of streptomycin was 32 μg/ml. All physiological, biochemical, chemotaxonomic and genomic characteristics support that strains JY-X040T and JY-X174 represent members of a novel species in a new genus, Changpingibacter yushuensis gen. nov., sp. nov. The type strain is JY-X040T (GDMCC 1.1996T = KCTC 49514T).

<P><B>Significance</B></P><P>Conventional, thermally driven continuous phase transitions are described by universal critical behavior that is independent of microscopic details of a specific material. An analogous description is lacking for phase transitions that are driven at absolute zero temperature by a nonthermal control parameter. Classification of quantum-driven phase transitions is a fundamental but open problem that arises in diverse contexts and multiple classes of materials. Here we report the first observation, to our knowledge, of a sharp Fermi surface reconstruction while applying a strong magnetic field to suppress an antiferromagnetic transition to zero temperature. These experiments demonstrate that direct measurements of the Fermi surface can distinguish theoretically proposed models of quantum criticality and point to a universal description of quantum phase transitions.</P><P>Conventional, thermally driven continuous phase transitions are described by universal critical behavior that is independent of the specific microscopic details of a material. However, many current studies focus on materials that exhibit quantum-driven continuous phase transitions (quantum critical points, or QCPs) at absolute zero temperature. The classification of such QCPs and the question of whether they show universal behavior remain open issues. Here we report measurements of heat capacity and de Haas–van Alphen (dHvA) oscillations at low temperatures across a field-induced antiferromagnetic QCP (<I>B</I><SUB>c0</SUB> ≈ 50 T) in the heavy-fermion metal CeRhIn<SUB>5</SUB>. A sharp, magnetic-field-induced change in Fermi surface is detected both in the dHvA effect and Hall resistivity at [Formula] ≈ 30 T, well inside the antiferromagnetic phase. Comparisons with band-structure calculations and properties of isostructural CeCoIn<SUB>5</SUB> suggest that the Fermi-surface change at [Formula] is associated with a localized-to-itinerant transition of the Ce-4<I>f</I> electrons in CeRhIn<SUB>5</SUB>. Taken in conjunction with pressure experiments, our results demonstrate that at least two distinct classes of QCP are observable in CeRhIn<SUB>5</SUB>, a significant step toward the derivation of a universal phase diagram for QCPs.</P>

Secure Consensus Control for Multi-agent Systems Subject to Consecutive Asynchronous DoS Attacks

Jiao Liu,Xin Wang 제어·로봇·시스템학회 2023 International Journal of Control, Automation, and Vol.21 No.1

This paper investigates the distributed secure consensus tracking control problem of the leader-following multi-agent systems (MASs) under consecutive asynchronous denial of service (DoS) attacks. Consecutive asynchronous DoS attacks cause the system to switch among communication subgraphs corresponding to different types of DoS attacks. Based on switching theory, the MAS subject to consecutive asynchronous DoS attacks can be modeled as a switched system with persistent dwell time (PDT). The sleep phase of DoS attacks is considered to be τ-portion in which the communication topology is assumed with a directed spanning tree. The activation phase of DoS attacks can be regarded as T-portion, where effective DoS attacks will destroy the spanning tree structure of the topologies. By constructing the topology-dependent Lyapunov functions, secure controller and persistent dwell time are co-designed to ensure consensus tracking of MASs in the attack environment. Finally, the effectiveness and advantage of the provided method are illustrated with an example.

Jiao Wu,Shan Zhao,Xin Chen,Yuanda Jiu,Junfeng Liu,Jinglin Gao,Shijie Wang 한국식품과학회 2023 Food Science and Biotechnology Vol.32 No.13

Honey quality is in relation to botanical origin, and physicochemical properties, elemental composition, and antioxidant activity have been used for assessment and identification of honeys. The goal of this study is to contribute to the general analysis of five unifloral honeys from Cocos nucifera L., Dalbergia benthami Prain, Bombax ceiba L., Castanea mollissima Bl., and mangrove in Hainan province, China. Our results revealed that B. ceiba honey had the highest pH (4.27), color (139.33 mm Pfund), ash content (1.03 g/100 g), and electrical conductivity (1312.00 μS/cm) in five unifloral honeys. Furthermore, B. ceiba honey also contained the highest levels of total phenolic content (75.54 mg GAE/100 g) and total flavonoid content (29.22 mg RE/100 g), as well as the strongest antioxidant activity (DPPH IC50 value, 3.97 mg/mL; FRAP value, 6527.43 µmol TE/kg). Moreover, we revealed a considerable variation in element contents in honeys using ICP-MS, with potassium being the most predominant element. B. ceiba honey had the highest contents of K, Ca, Mg, and P, whereas the highest amount of Na was found in mangrove honey. Overall, our data indicated that B. ceiba honey deserves further research as a potential antioxidant agent.
