Magnetic and Electronic Properties of β-Graphyne Doped with Rare-Earth Atoms

Structural, electronic and magnetic properties of La-, Ce-, Pr-, Nd-, Pm-, Sm-and Eu-doped β-graphyne are investigated by comprehensive ab initio calculation based on density functional theory. The adsorption energies indicate that the dopings are suitable. The doped β-graphyne undergoes transition from semiconductor to metal. Furthermore, the doping of Nd, Pm, Sm and Eu atoms can induce magnetization. The results are useful for spintronics and the design of future electronic devices.
Spin Transport under In-plane Electric Fields with Different Orientations in Undoped InGaAs/AlGaAs Multiple Quantum Wells

The spin-polarized photocurrent is used to study the in-plane electric field dependent spin transport in undoped InGaAs/AlGaAs multiple quantum wells. In the temperature range of 77-297 K, the spin-polarized photocurrent shows an anisotropic spin transport under different oriented in-plane electric fields. We ascribe this characteristic to two dominant mechanisms: the hot phonon effect and the Rashba spin-orbit effect which is influenced by the in-plane electric fields with different orientations. The formulas are proposed to fit our experiments, suggesting a guide of potential applications and devices.
Demonstration of a Sub-Sampling Phase Lock Loop Based Microwave Source for Reducing Dick Effect in Atomic Clocks

We demonstrate a simple scheme of 6.835 GHz microwave source based on the sub-sampling phase lock loop (PLL). A dielectric resonant oscillator of 6.8 GHz is directly phase locked to an ultra-low phase noise 100MHz oven controlled crystal oscillator (OCXO) utilizing the sub-sampling PLL. Then the 6.8 GHz is mixed with 35MHz from an direct digital synthesizer (DDS) which is also referenced to the 100MHZ OCXO to generate the final 6.835 GHz signal. Benefiting from the sub-sampling PLL, the processes of frequency multiplication, which are usually necessary in the development of a microwave source, are greatly simplified. The architecture of the microwave source is pretty simple. Correspondingly, its power consumption and cost are low. The absolute phase noises of the 6.835 GHz output signal are-47 dBc/Hz,-77 dBc/Hz,-104 dBc/Hz and-121 dBc/Hz at 1 Hz, 10 Hz, 100 Hz and 1 kHz offset frequencies, respectively. The frequency stability limited by the phase noise through the Dick effect is theoretically estimated to be better than 5.0 × 10~(-14)τ ~(1/2) when it is used as the local oscillator of the Rb atomic clocks. This low phase noise microwave source can also be used in other experiments of precision measurement physics.
Measurement of S-Wave Scattering Length between ~6Li and ~(88)Sr Atoms Using Interspecies Thermalization in an Optical Dipole Trap

We report the creation of the first mixture of ~6Li and ~(88)Sr atoms in an optical dipole trap. Using this mixture, a measurement of the interspecies thermalization process is carried out and the previously unknown interspecies s-wave scattering length between ~6Li and ~(88)Sr atoms is extracted to be |~(a6)Li-~(88)Sr| = (380+160-100)a_0 with a_0 being the Bohr radius from the rate of interspecies thermalization.
Modeling of suspended sediment by coupled wave-current model in the Zhujiang (Pearl) River Estuary

A three-dimensional wave-current-sediment coupled numerical model is developed to understand the sediment transport dynamics in the Zhujiang (Pearl) River Estuary (ZRE), China. The model results are in good agreement with observed data, and statistics show good model skill scores. Numerical studies are conducted to assess the scenarios of suspended sediment in the ZRE under the effects of different forcing (river discharges, waves, and winds). The model results indicate that the estuarine gravitational circulation plays an important role in the development of estuarine turbidity maximum in the ZRE, particularly during neap tides. The increased river discharge can result in a seaward sediment transport. The suspended sediment concentration (SSC) in the bottom increases with both wave bottom orbital velocity and wave height. Because of the shallow water depth, the effect of waves on sediment in the west shoal is greater than that in the east channel. The southwesterly wind-induced wave affects the SSC more than those resulting from the northeasterly wind, while the northeasterly wind-driven circulation has a slightly greater influence on the SSC than that of the southwesterly wind. However, a steady southwesterly wind condition favors the increase of the SSC in the Lingding Bay more so than a steady northeasterly wind condition. If the other forcings are same, the averaged SSC under a steady southwesterly wind condition is about 1.1 times that resulting from a steady northeasterly wind.
Rituximab in kidney disease and transplant

Rituximab is a chimeric monoclonal antibody that binds to CD20 antigen of B-cells. It depletes the level of mature B-cells by various mechanisms such as mediation of antibody-dependent cellular cytotoxicity, complement-dependent cytotoxicity, and B-cell apoptosis. Rituximab is a USFDA approved drug for clinical use in non-Hodgkin's B-cell lymphoma (NHL), rheumatoid arthritis, chronic lymphocytic leukemia (CLL), granulomatosis with polyangiitis and pemphigus vulgaris. It is also known for its “off label” use in renal disease and renal transplant worldwide. However, the exact mechanisms by which it exerts its effect in the aforementioned condition remain unclear but may be related to its long-term effects on plasma cell development and the impact on B-cell modulation of T cell responses. This review discusses the current use of rituximab in renal disease and renal transplantation, and its potential role in novel therapeutic protocols.
ADMM-based Distributed State Estimation for Integrated Energy System

In order to have an accurate knowledge of systemwide operation states, it is necessary to perform state estimation for the integrated energy system (IES) as the basis of energy management and control. Centralized state estimation is practically infeasible for IES due to the unreliability of communication, the barrier on privacy, and the large scale of integrated systems. This paper proposes a distributed state estimation algorithm based on the alternating direction method of multipliers (ADMM) for IES containing electricity, heat, and natural gas. Various coupling units are taken into full consideration in modeling of IES state estimation to reflect the harmonization of multi energy. On the basis of bilinear measurement model, the state estimation considering nonlinear measurements can be replaced by an equivalent three-stage problem containing two linear state estimations and an intermediate transformation to avoid nonconvex optimization. The three-stage procedure for IES state estimation can be further decoupled over three sub-systems with coordination on coupling units, yielding a fully distributed scheme based on ADMM. A modified ADMM with the selfadjusting penalty parameter is also adopted to enhance the convergence. Simulation results demonstrate the validity and superiority of the proposed algorithm.
Impact of Synchronous Condenser on the Dynamic Behavior of LCC-based UHVDC System Hierarchically Connected to AC System

Hierarchical connection (HC) is a very attractive mode for ± 800 kV line commutated converter based ultra high voltage direct current (LCC-UHVDC) system connected to different AC voltage levels because of its ability to reduce the scale factor of a converter transformer. Faults in the HC-UHVDC system can cause commutation failure (CF). In this paper, impact of synchronous condenser (SC) to mitigate CF in HC-UHVDC system is analyzed. A ± 800KV HC-UHVDC system along with synchronous condenser is built in PSCAD/EMTDC. Transient performance analysis of HC-UHVDC for single and three phase to ground faults is investigated. Commutation failure immunity index (CFII), commutation failure probability index (CFPI), fault recovery time (FRT), and transient overvoltage (TOV) are used as measures to evaluate the effects of SC at HC-UHVDC system design. The simulation results show that SC can make the HCUHVDC system less susceptible to CF, effectively improve fault recovery performances of the overall system, and reduce transient overvoltage when single or multiple converters are blocked. The results of this research can provide technical assistance in real world HC-UHVDC projects.
Multi-energy Storage System Model Based on Electricity Heat and Hydrogen Coordinated Optimization for Power Grid Flexibility

Based on decreasing the flexibility of the power grid through the integration of large-scale renewable energy, a multi-energy storage system architectural model and its coordination operational strategy with the same flexibility as in the pumped storage power station and battery energy storage system (BESS) are studied. According to the new energy fluctuation characteristics and the different peak valley parameters in the power grid, this paper proposes a electricity heat hydrogen multienergy storage system (EHH-MESS) and its coordination and optimization operational model to reduce the curtailment of wind power and photovoltaic (PV) to the power grid and improve the flexibility of the power grid. Finally, this paper studied the simulation model of an energy storage optimization control strategy after the multi-energy storage system is connected to the distribution networks, and analyzed three operational modes of the multi-energy storage system. The simulation results show that the EHH-MESS proposed in this paper has a better power grid regulation flexibility and economy, and can be used to replace the battery energy storage system based on MATLAB.
An Improved Support Vector Clustering Approach to Dynamic Aggregation of Large Wind Farms

In this paper, we propose an improved support vector clustering (SVC) algorithm to cluster wind turbines (WTs) in a wind farm (WF). A boundary points (BPs) detecting method based on the grid theory and the connected subdomain (CS) are proposed. Thus the efficiency of SVC is enhanced while maintaining the accuracy of the algorithm. As for the multiwind condition equivalent of WF, a method to determine the number and capacity of each of the aggregated wind turbines (AWTs) based on historical wind data is proposed. Only wind speed (WS) and wind direction (WD) of the WF are needed to calculate the WSs of each AWT. Results demonstrate that the algorithm proposed in this paper can cluster WTs quickly and accurately. And the dynamic aggregated models of the WFs are suitable for both the single-wind condition and multi-wind condition simulations, with high accuracy being obtained.
Effects of vegetation on the structure and diversity of soil bacterial communities in the Arctic tundra

The relatively simple vegetation of the Arctic tundra provides an ideal site in which to study the relationships between plants,bacterial communities and soil chemistry.Here,results of 16S rRNA gene sequencing of secondary Arctic brown soils collected from underneath colonies of Dryasoctopetala,Luzulaconfusa and Bistortavivipara in the Arctic tundra near Ny-Alesund,Svalbard,Norway,reveal significant differences in bacterial communities related to soil environmental properties.Redundancy analysis shows that all measured geochemical factors were significant in structuring microbiomes,with strong correlations related to soil pH and organic matter contents.Vegetation is likely to affect the physical and chemical properties of the soil,which in turn affects the bacterial community and composition of the soil.
Proto-Adamastor ocean crust (920 Ma) described in Brasiliano Orogen from coetaneous zircon and tourmaline

Proto-Adamastor ocean bathed Rodinia and successor continental fragments from 1.0-0.9 Ga up to 0.75 Ga, and evolved into world Adamastor Ocean at 0.75-0.60 Ga. Mesoproterozoic oceanic crust is poorly preserved on continents, only indirect evidence registered in Brasiliano Orogen. We report first evidence of ophiolite originated in proto-Adamastor. We use multi-technique U-Pb-Hf zircon and δ~(11)B tourmaline isotopic and elemental compositions. The host tourmalinite is enclosed in metaserpentinite, both belonging to the Bossoroca ophiolite. Zircon is 920 Ma-old, ε_(Hf(920 Ma)) = +12, Hf_(TDM) = 1.0 Ga and has 'oceanic' composition (e.g., U/Yb< 0.1). Tourmaline is dravite with δ~(11)B = +1.8%o (Tur 1), 0‰ (Tur 2),-8.5‰ (Tur 3). These characteristics are a novel contribution to Rodinia and associated world ocean, because a fragment of proto-Adamastor oceanic crust and mantle evolved at the beginning of the Brasiliano Orogen.
Ophiolites of the Central Asian Orogenic Belt: Geochemical and petrological characterization and tectonic settings

We present a compilation of published data (field, petrography, ages and geochemistry) from 73 ophiolitic complexes of the Central Asian Orogenic Belt. The ophiolitic complexes, ranging in age from Neoproterozoic to Triassic, have been geochemically classified as subduction-related and subduction-unrelated categories applying recent, well-established discrimination diagrams. The subduction-unrelated category is further subdivided into Mid-Ocean Ridge type (MOR), a common rift-drift stage and Plume type, and the subduction-related category is subdivided into Backarc (BA), Forearc (FA), Backarc to Forearc (BA-FA) and Volcanic Arc (VA) types. The four subduction-related types define highly different geochemical features, with the BA and FA types defining end members showing subduction influence of 10%-100% and 90%-100% subduction influence, respectively, and the two other types (BA-FA and VA) define values between the two end members. The subduction-related category comprises 79% of the examined ophiolites, of which the BA type ophiolites is by far the dominant group, followed by the BA-FA type, and with FA and VA types as subordinate groups. The Neoproterozoic and Ordovician complexes exhibit the highest, whereas those of Silurian age exhibit the lowest subduction-influence. Of the remaining 21% subduction-unrelated ophiolites, the MOR type dominates. Both the subduction-related and subduction-unrelated types, in particular the latter, are commonly associated with alkaline basalts taken to represent ocean island magmatism. Harzburgite, dunite, gabbro and basalt are the common lithologies in all ophiolite types, whereas the BA-FA, FA and VA types generally contain intermediate to felsic rocks, and in the FA type boninites occur. The subduction-related ophiolites types generally show low metamorphic grade, whereas greenschist, amphibolite and blueschist grades occur in the subduction-unrelated and BA types. The highly different subduction contribution (from 0 to 100% in the MOR and FA, respectively), attest to variable dips of the subducting slab, as well as variable flux of subduction-related elements into the mantle above subducting slabs, from where the ophiolite magmas got their geochemical fingerprints. As most MOR ophiolites get subducted to the deep mantle, the subduction-related ophiolites have become a dominant ophiolitic type on Earth's surface through all times supporting the idea about the early start of Plate Tectonics.
Zircon U-Pb and Lu-Hf isotope constraints on Archean crustal evolution in Southeastern Guyana Shield

The southeastern Guyana Shield, northeast Amazonian Craton, in the north of Brazil, is part of a widespread orogenic belt developed during the Transamazonian orogenic cycle (2.26-1.95 Ga) that includes a large Archean continental landmass strongly reworked during the Transamazonian orogeny, named Amapa Block. It consists mainly of a high-grade metamorphic granulitic-migmatitic-gneiss complex, of Meso-to Neoarchean age and Rhyacian granitoids and supracrustal sequences. For the first time, coupled U-Pb and Lu-Hf isotope data were obtained on zircon by LA-ICP-MS from five tectono-stratigraphic units of the Archean basement and one Paleoproterozoic intrusive rock, in order to investigate the main episodes of crustal growth and reworking. Whole-rock Sm-Nd isotope data were compared to the zircon Lu-Hf data. Three main magmatic episodes were defined by U-Pb zircon dating, two in the Mesoarchean (~3.19 Ga and 2.85 Ga) and one in the Neoarchean (~2.69-2.65 Ga). Subchondritic εHf(t) values obtained for almost all investigated units indicate that crustal reworking processes were predominant during the formation of rocks that today make up the Amapa Block. Hf-T_(DM)~C model ages, ranging from 2.99 Ga to 3.97 Ga, indicate that at least two important periods of mantle extraction and continental crust formation occurred during the Archean in southeastern Guyana Shield, an older one in the Eoarchean (~4.0 Ga) and a younger one in the Mesoarchean (~3.0-3.1 Ga). The latter is recognized as an important period of crustal accretion worldwide. The recognition of an Eoarchean episode to the southeastern most part of the Guyana Shield is unprecedented and was not recorded by whole-rock Sm-Nd data, which were restricted to the Meso-Paleoarchean (2.83 Ga to 3.51 Ga). This finding reveals that continental crust generation in the Amazonian Craton began at least 500 Ma earlier than previously suggested by the SmNd systematics.
Origin and Evolution of Core Components Responsible for Monitoring Light Environment Changes during Plant Terrestrialization

Light serves as the source of energy as well as an information signal for photosynthetic plants. During evolution, plants have acquired the ability to monitor environmental light radiation and adjust their developmental patterns to optimally utilize light energy for photosynthesis. The mechanisms of light perception and signal transduction have been comprehensively studied in past decades, mostly in a few model plants, including Arabidopsis thaliana. However, systematic analyses of the origin and evolution of core components involved in light perception and signaling are still lacking. In this study, we took advantage of the recently sequenced genomes and transcriptomes covering all the main Archaeplastida clades in the public domain to identify orthologous genes of core components involved in light perception and signaling and to reconstruct their evolutionary history. Our analyses suggested that acclimation to different distribution of light quality in new environments led to the origination of specific light signaling pathways in plants. The UVR8 (UV Resistance Locus 8) signaling pathway originated during the movement of plants fromthe deeper sea to shallow water and enabled plants to deal with ultraviolet Blight (UV-B). After acquisition of UV-B adaptation, origination of the phytochrome signaling pathway helped plants to colonize water surface where red light became the prominent light energy source. The seedling emergence pathway, which is mediated by a combination of light and phytohormone signals that orchestrate plant growth pattern transitions, originated before the emergence of seed plants. Although cryptochromes and some key components of E3 ubiquitin ligase systems already existed before the divergence of the plant and animal kingdoms, the coevolution and optimization of light perception and downstream signal transduction components, including key transcription factors and E3 ubiquitin ligase systems, are evident during plant terrestrialization.

The role of connexin 43 in neuropathic pain induced by spinal cord injury

Neuropathic pain is caused by the damage or dysfunction of the nervous system.In many neuropathic pain models,there is an increase in the number of gap junction (GJ) channels,especially the upregulation of the expression of connexin43 (Cx43),leading to the secretion of various types of cytokines and involvement in the formation of neuropathic pain.GJs are widely distributed in mammalian organs and tissues,and Cx43 is the most abundant connexin (Cx) in mammals.Astrocytes are the most abundant glial cell type in the central nervous system (CNS),which mainly express Cx43.More importantly,GJs play an important role in regulating cell metabolism,signaling,and function.Many existing literatures showed that Cx43 plays an important role in the nervous system,especially in the CNS under normal and pathological conditions.However,many internal mechanisms have not yet been thoroughly explored.In this review,we summarized the current understanding of the role and association of Cx and pannexin channels in neuropathic pain,especially after spinal cord injury,as well as some of our own insights and thoughts which suggest that Cx43 may become an emerging therapeutic target for future neuropathic pain,bringing new hope to patients.
帕唑帕尼致深静脉血栓形成1例

在上皮性卵巢癌中,透明细胞癌属少见卵巢恶性肿瘤。目前最佳的治疗方式为肿瘤细胞减灭术和以铂类联合紫杉醇为主的化疗,而效果仍不满意。近年来,针对多种信号通路的酪氨酸激酶抑制剂、单抗类药物和多肽等已成为研发热点,其中抗血管生成药物在卵巢癌的治疗中效果最好。帕唑帕尼(pazopanib)是一种口服小分子多靶点酪氨酸激酶抑制剂,作用于细胞信号转导通路中的血管内皮生长因子受体(VEGFR- 1、- 2、 - 3)、血小板源性生长因子受体(PDGFR- α、- β)、干细胞因子受体(c- kit),从而具有抗内皮细胞增殖和抗肿瘤新生血管生成的作用。美国食品和药物管理局(FDA)分别于2009年和2012年批准帕唑帕尼用于治疗晚期肾细胞癌和软组织肉瘤,该药是否适用于卵巢癌仍在试验中。帕唑帕尼治疗复发性卵巢癌具有较好疗效,但不良反应较多,如高血压、疲劳、腹泻等,目前作者尚未见国内有关帕唑帕尼引起静脉血栓栓塞的报道,本文报道1例患者因口服帕唑帕尼治疗复发性卵巢癌后出现下肢深静脉血栓形成(deep venous thrombosis, DVT)。
Effect of Alloying Element on Electromagnetic Interference Shielding Effectiveness of Binary Magnesium Alloys

The microstructure, electrical conductivity and electromagnetic interference shielding effectiveness of Mg-X (X = Al, Sn, Y and Gd) alloys in as-cast and solution states were systematically investigated in this study. The electrical conductivity and electromagnetic shielding capacity of binary magnesium alloys decrease linearly with alloying element content. The electromagnetic shielding effectiveness of the binary magnesium alloys with the same alloying element content is as follows: Mg-Gd < Mg-Sn < Mg-Y < Mg-Al. The main reason for the differences in electromagnetic interference shielding of the binary magnesium alloys is the change in conductivity, which is mainly affected by volumetric difference of solute atoms and magnesium atoms, solute atomic valence and configuration of extranuclear electron.
