Collective Entity Alignment for Knowledge Fusion of Power Grid Dispatching Knowledge Graphs

Knowledge graphs (KGs)have been widely accepted as powerful tools for modeling the complex relationships between concepts and developing knowledge-based services. In recent years, researchers in the field of power systems have explored KGs to develop intelligent dispatching systems for increasingly large power grids. With multiple power grid dispatching knowledge graphs (PDKGs)constructed by different agencies, the knowledge fusion of different PDKGs is useful for providing more accurate decision supports. To achieve this, entity alignment that aims at connecting different KGs by identifying equivalent entities is a critical step. Existing entity alignment methods cannot integrate useful structural, attribute, and relational information while calculating entities' similarities and are prone to making many-to-one alignments, thus can hardly achieve the best performance. To address these issues, this paper proposes a collective entity alignment model that integrates three kinds of available information and makes collective counterpart assignments. This model proposes a novel knowledge graph attention network (KGAT)to learn the embeddings of entities and relations explicitly and calculates entities' similarities by adaptively incorporating the structural, attribute, and relational similarities. Then, we formulate the counterpart assignment task as an integer programming (IP)problem to obtain one-to-one alignments. We not only conduct experiments on a pair of PDKGs but also evaluate our model on three commonly used cross-lingual KGs. Experimental comparisons indicate that our model outperforms other methods and provides an effective tool for the knowledge fusion of PDKGs.
Explosion temperature mapping of emulsion explosives containing TiH2 powders with the two-color pyrometer technique

In the study, the two-color pyrometer technique was used to measure the transient temperature field of emulsion explosives with different contents of TiH2 powders. The experimental results showed that the introduction of TiH2 powders could significantly increase the explosion temperature and fireball duration of emulsion explosive. When emulsion explosives were ignited, the average explosion temperature of pure emulsion explosive continuously decreased while emulsion explosives added with TiH2 powders increased at first and then decreased. When the content of TiH2 powders was 6 mass%, the explosion average temperature reached its maximumvalue of 3095 K, increasing by 43.7% as compared with that of pure emulsion explosive. In addition, the results of air blast experiment and explosion heat test showed that the variation trends of shock wave parameters, explosion heat and theoretical explosion temperature of emulsion explosives with different contents of TiH2 powders were basically consistent with that of explosion temperature measured by the two-color pyrometer technique. In conclusion, the two-color pyrometer technique would be conducive to the formula design of emulsion explosive by understanding the explosion temperature characteristics.
Broadband and high efficiency terahertz metasurfaces for anomalous refraction and vortex beam generation

The applications of metasurfaces are currently a highly active research field due to their extraordinary ability to manipulate electromagnetic waves.The ultra-thin characteristics of metasurfaces allow the miniaturization and integration of metasurface devices.However,these devices work typically under a low efficiency and narrow bandwidth condition.In this work,we design eight multilayered unit cells with similar amplitudes and a phase interval of π/4,which convert the polarization states of the terahertz (THz) waves between two orthogonal directions.The average cross-polarized transmission amplitudes of these cells are all around 0.9 in an ultra-broad frequency range from 0.5 THz to 1.4 THz.Furthermore,unit cells are used to construct both an ultra-thin anomalous refraction metalens and a vortex phase plate.Our simulation results show that the anomalous refraction for the transmitted linear polarization component is comparable to the theoretical prediction,and the maximum error is determined to be below 4.8%.The vortex phase plate can also generate an ideal terahertz vortex beam with a mode purity of 90% and more.The distributions of longitudinal electric field,intensity,and phase illustrate that the generated vortex beam has excellent propagation characteristics and a weak divergence.Simulations of the two types of metasurface devices,based on the eight unit cells,exhibit very high efficiencies in a wide bandwidth.Our research will assist in the improvement in the practical applications of metasurfaces.It also provides a reference for the design of high efficiency and broadband devices that are applied to other frequency ranges.
Recent advances in quasi-2D superconductors via organic molecule intercalation

Superconductivity at the 2D limit shows emergent novel quantum phenomena,including anomalously enhanced Hc2,quantum metallic states and quantum Griffiths singularity,which has attracted much attention in the field of condensed matter physics.In this article,we focus on new advances in quasi-2D superconductors in the bulk phase using an organic molecular electrochemical intercalation method.The enhanced superconductivity and emergent pseudogap behavior in these quasi-2D superconductors are summarized with a further prospect.
Unusual thermodynamics of low-energy phonons in the Dirac semimetal Cd_3As_2

By studying the thermal conductivity,specific heat,elastic modulus,and thermal expansion as a function of temperature for Cd_3As_2,we have unveiled a couple of important thermodynamic features of the low-energy phonons strongly interacting with Dirac electrons.The existence of soft optical phonons,as inferred from the extremely low thermal conductivity,is unambiguously confirmed by low-temperature specific heat revealing significant deviation from Debye's description.The estimated Debye temperature is small in the range of 100-200 K and varies significantly depending upon the measurement used in its experimental determination.The thermodynamic Gruneisen ratio γ reveals a remarkable reduction below about 100 K,an energy scale that is highly relevant to the Dirac states,towards negative values below about 10 K that are indicative of lattice instability.
Molecule opacity study on low-lying states of CS

CS molecule,which plays a key role in atmospheric and astrophysical circumstances,has drawn great attention for long time.Owing to its large state density,the detailed information of the electronic structure of CS is still lacking.In this work,the high-level MRCI+Q method is used to compute the potential energy curves,dipole moments and transition dipole moments of singlet and triplet states correlated with the lowest dissociation limit of CS,based on which high accurate vibration-rotation levels and spectroscopic constants of bound states are evaluated.The opacity of CS relevant to atmospheric circumstance is computed at a pressure of 100 atms for different temperatures.With the increase of temperature,band systems from different transitions mingle with each other,and band boundaries become blurred,which are originated from the increased population on vibrational excited states and electronic excited states at high temperature.
Mechanisms of the Traditional Chinese HerbAtractylodes lancea against COVID-19 Based on Network Pharmacology and Molecular Docking

Atractylodes lancea (Thunb.) DC.(AL) has been proven to be effective in the treatment of coronavirus disease 2019 (COVID-19).In this study,TCMSP,TCMID,OMIM,GeneCards,PharmMapper and SwissTargetPrediction were used to collect potential targets for AL against COVID-19.The online STRING analysis platform and Cytoscape were used for generating a (protein-protein interaction) PPI network.The Cytoscape and Autodock software were used for determining hub genes and key compounds.Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed via DAVID database.A total of 84 common targets were obtained.The antiviral pathways were main pathways in traetment.10 hub genes and key compounds were screened by CytoHubba.We found that AL2,AL6 and AL38 had lower binding energy with key proteins.Our study demonstrated that AL might be used to treat COVID-19 by improving the "cytokine storm",regulating some antiviral pathways,and inhibiting the key protein through which the SARS-CoV-2 invades the host cell.These findings give a pharmacological basis and support for treating COVID-19 with AL.
Two New Lipschitz Type Spaces and Their Characterizations

In this paper, we first introduce the weak Lipschitz spaces WLip_(q,α), 1 < q < ∞, 0 < α < 1 which are the analog of weak Lebesgue spaces L~(q,∞) in the setting of Lipschitz space. We obtain the equivalence between the norm ||·||Lip α and ||·||WLip_(q,α). As an application, we show that the commutator M_β~b is bounded from L~p to L~(q,∞) for some p ∈ (1, ∞) and 1/p-1/q=α+β/n if and only if b is in Lip_α. We also introduce the weak central bounded mean oscillation space WCBMO_(q,α) and give a characterization of WCBMO_(q,α) via the boundedness of the commutators of Hardy type operators.
Path of Rural Sustainable Development Based on the Evolution and Interaction of Rural Functions: A Case Study of Chongqing Municipality, China

In order to investigate the evolutionary characteristics of rural functions and their interaction, 37 districts and counties in Chongqing, China are used as research objects to measure the level of rural functions and analyze the interaction between rural functions using entropy value method and spatial autocorrelation method. The results show that from 2009 to 2019, the three main functions of production, living and ecology in Chongqing's villages have been greatly enhanced, especially the production function. On the whole, the production and living functions are stronger in the western part, while the ecological functions are significant in the eastern and southern parts of Chongqing, with some differences in local spatial characteristics. This finding is consistent with the regional economic and social development of Chongqing. In addition, the interaction between rural functions is also evident. In general, production and living functions are mainly expressed in synergistic relationships. Ecological and production functions, including ecological and subsistence functions, mainly present a trade-off relationship. The interactions between rural functions also show clear spatial and temporal differences. In addition, different regions have different comparative advantage functions, and in this study, the counties of Chongqing are classified into four types. Policy makers are advised to adopt different measures according to the different types to promote sustainable rural development by coordinating the ‘production-living-ecological ' functions of rural areas. This study reveals the spatio-temporal evolution of rural functions and the interaction between rural functions, which can provide theoretical support and practical reference for rural revitalisation and sustainable development.
Microstructure and mechanical properties of WC-(Ti,M)(C,N)- Co cemented carbides with different nitrogen contents

Three kinds of (Ti,M)(C_(1-x),N_x) (M = Ta,Nb,W) quaternary solid-solution powders with various nitrogen contents were synthesized by carbothermal reduction- nitridation (CRN) process.Effect of nitrogen content on the microstructure and mechanical properties of WC-(Ti,M)(C_(1-x),N_x)-Co cemented carbides fabricated by sinterhot isostatic pressing (HIP) were systematically investigated in this paper.The results show that the nitrogen content in the carbonitride raw powders strongly influences the morphology,the grain size and the compositions of the cemented carbides.All the cemented carbides with different nitrogen contents have a similar microstructural appearance:weak core-rim structure consisting of solidsolution phase embedded in WC-Co system.It is also observed that the carbonitride solid solution could somewhat reduce the WC grain growth,and the effectiveness of refining and the rim thickness are sensitively related to the nitrogen content of (Ti,M)(C_(1-x),N_x) solid solutions.In addition,with an increase in the nitrogen content,mechanical properties of these hard metals are enhanced,which were discussed in terms of the constituent,the microstructure and the solution behavior of the carbonitride solid solutions.
Rational design of heterostructured core-shell Co-Zn bimetallic selenides for improved sodium-ion storage

Bimetallic selenide with core-shell structure (CoSe_2/ZnSe/NC@ZnSe/NC) has been successfully prepared through facile carbonization and selenization processes of its core-shell metal-organic framework precursors,in which the precursor is synthesized by epitaxial growth of zinc-based zeolite imidazolate framework (ZIF-8) on the surface of cobalt-based and zinc-based zeolite imidazolate framework (ZIF-67@ZIF-8).The core- shell structure has the advantage of alleviating the volume expansion during repeated insertion and extraction of sodium ions which can effectively avoid structural collapse.Additionally,bimetallic selenides and heterostructure are effective strategies to greatly improve the rate capability of the material.Therefore,the core-shell structural CoSe_2/ZnSe/NC@ZnSe/NC material can maintain the original dodecahedron structure and delivers a specific capacity of 308.6 mAh·g~(-1) at 1.0 A·g~(-1) after 300 cycles with the desirable capacity retention of 90%.With the synergistic effects of heterostructure and core-shell structure,CoSe_2/ZnSe/NC@ZnSe/NC exhibits better electrochemical performance than CoSe_2/ZnSe/NC and CoSe_2/NC.These prove that both core-shell structure and heterostructure have positive effects on improving the electrochemical properties of materials.
Theoretical research into low-voltage Na_2TiSiO_5 anode for lithium-ion battery

Na_2TiSiO_5 (NTSO) is a low-cost Li-ion battery anode with great application potential,such as the tetragonal NTSO (T-NTSO) with a high capacity and a low voltage.In addition to the tetragonal structure,NTSO has two other polymorphs.However,the basic understanding of the structure,ion insertion and transport mechanisms of these new materials is still lacking.Herein,we present a combined experimental and computational investigation of the tetragonal and orthorhombic NTSO to reveal the intrinsic mechanism leading to the superior electrochemical performance of T-NTSO.We determined that the insertion site with a flexible Ti~(4+)/Ti~(3+) redox pair is critical for Li~+ insertion stability.The large number of such flexible sites in the T-NTSO results in a higher capacity and higher ionic conductivity than those of orthorhombic polymorph.The understanding of intrinsic properties will accelerate the development and utilization of titanosilicates as the next generation low-voltage anode of Li-ion battery.
Advanced sodium-ion capacitor based on antimony-carbon composite anode

Alloy-type materials with the characteristics of high theoretical capacity,low sodiation/desodiation potential,and good conductivity are considered as one of the most promising anodes for sodium-ion batteries or capacitors.However,the large volume change during the sodiation leads to poor cyclability and slow kinetics,thus presenting the main issue impeding the practical application.Herein,we propose a facile wet chemistry and pyrolysis method to synthesize Sb-carbon composite that Sb nanoparticles or single atoms are confined and/or dispersed in the wrinkled carbon framework with high nitrogen content.This unique architecture of Sb-carbon composite increases atomic interface contact/interaction with Na~+,facilitating ion diffusion and alleviating the volume change of Sb during the charge/discharge process.Half-cell test shows that Sb-carbon composite exhibits a high-rate capability and stable cycling life.Furthermore,sodium-ion capacitors fabricated by employing Sb-carbon composite as anode and home-made active carbon as cathode,deliver both high-energy density of 157 Wh·kg~(-1) and high-power density of 25 kW·kg~(-1) as well as excellent cycling performance exceeding 4000 cycles.
Recent advances and perspectives on prelithiation strategies for lithium-ion capacitors

Lithium-ion capacitors (LICs),consisting of a capacitor-type material and a battery-type material together with organic electrolytes,are the state-of-the-art electrochemical energy storage devices compared with supercapacitors and batteries.Owing to their unique characteristics,LICs received a lot of attentions,and great progresses have been achieved,especially in the exploration of cathode and anode materials.Prelithiation techniques are regarded as indispensable procedures for LICs systems,which can compensate for the initial irreversible capacity loss,increase the Li~+ concentration in the electrolyte,raise the working voltage and resolve the safety and cycle stability issues;however,its research progress is slow,and there is not enough attention until now.In this overview,we look into the ongoing processes on the recent development of prelithiation technologies,especially in organic electrolyte consumption-type LICs.In particular,some prelithiation strategies for LICs are summarized and discussed in detail,including the ex situ electrochemical method,in situ electrochemical method,and cathode prelithiation additives method.Moreover,we propose some unresolved challenges and prospects for prelithiation technologies from the basic research ideas and future key research directions.This work aims to bring up new insights to reassess the significance of premetallation strategies for advanced hybrid-ion capacitors based on the currently proposed prelithiation strategies.
PRIMAL-DUAL PATH-FOLLOWING METHODS AND THE TRUST-REGION UPDATING STRATEGY FOR LINEAR PROGRAMMING WITH NOISY DATA

In this article,we consider the primal-dual path-following method and the trust-region updating strategy for the standard linear programming problem.For the rank-deficient problem with the small noisy data,we also give the preprocessing method based on the QR decomposition with column pivoting.Then,we prove the global convergence of the new method when the initial point is strictly primal-dual feasible.Finally,for some rank-deficient problems with or without the small noisy data from the NETLIB collection,we compare it with other two popular interior-point methods,i.e.the subroutine pathfollow.m and the built-in subroutine linprog.m of the MATLAB environment.Numerical results show that the new method is more robust than the other two methods for the rank-deficient problem with the small noise data.
Vitamin A supplementation downregulates ADH1C and ALDH1A1 mRNA expression in weaned beef calves

Our previous studies demonstrated that oral vitamin A supplementation during late-stage pregnancy and the neonatal stage enhances birth weight, growth performance, and mRNA expression related to muscle and preadipocyte development in beef cattle. The alcohol dehydrogenase 1C (ADH1C) c.-64T >C genotype also correlated with vitamin A concentration in beef production. This study aimed to investigate the effects of vitamin A supplementation on the muscle development and vitamin A metabolism in weaned beef calves with different ADH1C genotypes. Twenty male calves (90 d of age; initial BW: 89.03 kg [SD 8.60]) were stratified according to ADH1C genotype and vitamin A treatment (duration: 3 months) and randomly assigned to 4 groups with a 2×2 factorial arrangement. Vitamin A treatments included the following: control (10,000 IU/kg of as-fed, a. TT type; b. TC type); treatment (40,000 IU/kg of as-fed, c. TT type; and d. TC type). Parameters including BW, FI, blood, longissimus dorsi muscle, and liver status during the experimental period were analyzed using the generalized linear model (GLM) procedure and Tukey's test by SAS 9.4 program. Serum vitamin A was significantly increased (P < 0.05) in the vitamin A treatment group at 4 and 6 months of age. TT type calves showed higher serum vitamin A concentration (P < 0.05) than the TC type calves. Serum triglyceride and non-esterified fatty acid (NEFA) levels increased (P < 0.05) in the treatment group compared with the control at 6 months of age. However, BW, ADG and FI showed no differences between the groups. In addition, mRNA expression in longissimus dorsi muscle revealed upregulation of paired box 7 (PAX7) (P < 0.05) after the vitamin A treatment period based on biopsy results. Both ADH1C and aldehyde dehydrogenase (ALDH) 1A1 mRNA expression was downregulated (P < 0.01) by vitamin A supplementation. The TC type of ADH1C showed higher mRNA expression than the TT type. However, no effect was observed on adipogenic mRNA expression (preadipocyte factor-1 [PREF-1], peroxisome proliferator-activated receptor gamma [PPARy], fatty acid binding protein 4 [FABP4]) in all groups. Our findings suggest that weaned calves treated with vitamin A may promote the storage of satellite cells by elevating PAX7 gene expression in the muscle. The TC type calves may show increased capacity for vitamin A metabolism, which can be used in genetically customizing feed management to maximize beef production in the calves.
脓毒症中内皮细胞高通透性的机制研究进展

脓毒症常由感染引起宿主免疫和过度炎症反应,是非心源性危重症患者死亡的主要原因之一。正常情况下,循环的微血管内皮细胞结合紧密并与基膜形成半通透性屏障,仅限于水和电解质外渗;脓毒症时,强烈的炎症刺激导致血管内皮屏障功能受损,对溶质分子的选择性丧失、渗透性增加并导致血管大分子渗漏,从而形成组织水肿和器官损伤。脓毒症早期,病原体引起的过度炎症反应常伴有严重的微血管功能障碍,从而导致多器官功能不全甚至循环衰竭。因此,微血管内皮细胞损伤和微循环障碍是引发脓毒症中多器官功能障碍的重要环节,改善血管的内皮屏障功能和微血管的渗漏对控制病情进展及降低脓毒症的病死率具有重要意义。
个体强化干预在老年肌少症合并认知功能障碍中的应用分析

肌少症的发生与年龄密切相关,多见于老年人群,临床以骨骼肌肌量下降、肌力减退等特征性改变为主,可出现躯体活动障碍、认知功能障碍等常见表现,从而导致跌倒、生活质量下降等诸多不良结局。研究已证实,肌少症和认知功能障碍存在密切相关性,且两者的危险因素存在一定共性,如老年、不良生活方式、代谢紊乱、机体持续炎症反应等。肌少症患者一旦合并认知功能障碍,则可能进一步增加痴呆、跌倒甚至死亡的风险,给家庭和社会带来沉重的照护负担和精神负担。既往对于肌少症患者的护理干预多以肢体功能恢复为主导,未能对认知功能的干预给予足够重视,大多采用程式化干预,个体强化干预措施的实施力度不足,亦未能形成完整的护理干预方案,这可能导致患者认知功能的改善无法达到预期效果。鉴于此,浙江大学医学院附属第一医院在既往护理干预的基础上,制定护士主导的个体强化干预方案,以期为老年肌少症合并认知功能障碍患者生活质量的改善提供参考,现报告如下。
