Dysderidae C. L. Koch, 1837 is reported from China for the first time. A new species of the genus Dysdera Latreille, 1804, D. dushengi sp. nov. from Xinjiang Uygur Autonomous Region, is described based on both sexes. The new species is closely related to D. pamirica Dunin, 1992, a species known from adjacent Tajikistan.
Genetic analysis and ecological niche modeling delimit species boundary of the Przewalski’s scorpion (Scorpiones: Buthidae) in arid Asian inland

Reliable delimitation of venomous scorpions is not only consequential to toxicological studies but also instructive to conservation and exploration of these important medical resources. In the present study, we delimited species boundary for the the Przewalski’s scorpion from arid northwest China through a combined approach employing phylogenetic analysis, ecological niche modeling and morphological comparison. Our results indicate that the Przewalski’s scorpion represent an independent taxonomic unit and should be recognized as full species rank, Mesobuthus przewalskii stat. nov. This species and the Chinese scorpion M. martensii represent the eastern members of the M. caucasicus species group which manifests a trans-Central Asia distribution across the Tianshan Mountains range. We also discussed the likely geographic barrier and climatic boundary that demarcate distributional range of the the Przewalski’s scorpion.
脉络膜骨瘤合并视网膜下积液诊疗一例

近年来,抗血管内皮生长因子(vascular endothelial growth factor,VEGF)药物不仅用于年龄相关性黄斑变性、高度近视眼底病变等新生血管性眼病的治疗,还用于治疗脉络膜肿瘤,如痣形成脉络膜新生血管。一些研究表明,在无CNV的脉络膜骨瘤中,浆液性脱离为视力下降的主要原因,也有一些研究表明,抗VEGF药物治疗可用于无CNV脉络膜骨瘤的治疗,且视力明显提高。Vayalambrone等曾报道1例11岁女性患者,双眼诊断为伴视网膜下积液不伴CNV的脉络膜骨瘤,经3次玻璃体腔注射雷珠单抗治疗后视网膜积液吸收且视力提高。Song等对5例合并视网膜下积液但不合并CNV的脉络膜骨瘤患者进行玻璃体腔贝伐单抗注射治疗,结果显示4例视网膜下积液吸收且视力提高。本例患者无CNV形成,但OCT提示视网膜下积液,首次行抗VEGF药物康柏西普治疗,术后1 d及1周视力及CMT值均未见明显改善,术后1个月CMT值下降,与Song等结果相似,但患者视力未见提高,考虑可能与患者对康柏西普应答缓慢有关。行第2次抗VEGF治疗后1个月,视力及CMT值未见改善,PDT治疗后OCT检查可见左眼视网膜下积液消失,且视力明显提高,OCT显示视网膜平伏,术后随访半年,患者视力稳定。既往研究表明,PDT用于治疗伴有CNV形成的脉络膜骨瘤,效果显著。本例患者2次抗VEGF药物治疗后视网膜下积液未见明显消退,虽患者不合并CNV,但行PDT后视网膜下积液消退显著,视力明显提高且随访半年视力仍较稳定,表明对于脉络膜骨瘤合并视网膜下积液时,若抗VEGF治疗未见效果,可考虑PDT治疗,但仍需进一步随访以明确疗效。
Redox evolution of western Tianshan subduction zone and its effect on deep carbon cycle

Knowing the phase relations of carbon-bearing phases at high-pressure (HP) and high-temperature (HT) condition is essential for understanding the deep carbon cycle in the subduction zones.In particular,the phase relation of carbon-bearing phases is also strongly influenced by redox condition of subduction zones,which is poorly explored.Here we summarized the phase relations of carbon-bearing phases (calcite,aragonite,dolomite,magnesite,graphite,hydrocarbon) in HP metamorphic rocks (marble,metapelite,eclogite) from the Western Tianshan subduction zone and high-pressure experiments.During prograde progress of subduction,carbonates in altered oceanic crust change from Ca-carbonate (calcite) to Ca,Mg-carbonate (dolomite),then finally to Mg-carbonate (magnesite) via Mg-Ca cation exchange reaction between silicate and carbonate,while calcite in sedimentary calcareous ooze on oceanic crust directly transfers to high-pressure aragonite in marble or amorphous CaCO_3 in subduction zones.Redox evolution also plays a significant effect on the carbon speciation in the Western Tianshan subduction zone.The prograde oxygen fugacity of the Western Tianshan subduction zone was constrained by mineral assemblage of garnet-omphacite from FMQ - 1.9 to FMQ - 2.5 at its metamorphic peak (maximum P-T) conditions.In comparison with redox conditions of other subduction zones,Western Tianshan has the lowest oxygen fugacity.Graphite and light hydrocarbon inclusions were ubiqutously identified in Western Tianshan HP metamorphic rocks and speculated to be formed from reduction of Fe-carbonate at low redox condition,which is also confirmed by high-pressure experimental simulation.Based on petrological observation and high-pressure simulation,a polarized redox model of reducing slab but oxidizing mantle wedge in subduction zone is proposed,and its effect on deep carbon cycle in subduction zones is further discussed.
Garnet fractionation,progressive melt loss and bulk composition variations in anatectic metabasites:Complications for interpreting the geodynamic significance of TTGs

Tonalite-trondhjemite-granodiorite (TTG) suites constitute a large proportion of the Archean geological record;however,the geodynamic processes that generated them,and Archean continental crust in general,remain a subject of debate.The concentrations and ratios of Sr,Y,La,Yb,Nb,and Ta in TTGs are commonly used to determine the depth of melting of their metabasic sources.The trace element composition of melt produced by metabasic source rocks during anatexis is strongly affected by the presence and abundance of pressure-sensitive minerals,such as plagioclase (Sr-bearing),garnet (Y- and HREE-bearing),and rutile (Nb- and Ta-bearing).Elevated Sr/Y and La/Yb ratios and low concentrations of Nb and Ta in TTGs are generally considered to indicate melting at high pressures (≥2.0 GPa).The depth of melting is a key factor in determining the origin of TTGs as this provides critical information on the tectonic setting of their generation.We use phase equilibrium and trace element modelling to explore the effects of three potential influences on TTG trace element compositions:fractionation of trace elements into peritectic garnet cores,progressive melt loss from the source,and source bulk composition.We model three different compositions of Archean basalts along thermal gradients of 500 °CI GPa,750 °CI GPa,and 1000 °CIGPa.The models produce major and trace element melt compositions that are generally consistent with measured compositions of TTGs.Although Sr/Y,La/Yb,Nb,and Ta exhibit pressure-dependent behaviour,other factors also affect these values.Garnet fractionation causes Sr/Y and La/Yb to reach much greater values and in this scenario,the values also increase with increasing temperature.Source bulk composition has an effect in all scenarios and most strongly influences La/Yb,Nb,and Ta.Overall,these results show that Sr/Y,La/Yb,Nb,and Ta can reach values generally considered to be indicative of high pressure melting at a range of P-T conditions including P< 2.0 GPa.Consequently,trace element compositions of TTGs alone may provide a misleading impression of the depth of melting of metabasites and the geodynamic environment of Archean crustal growth and reworking.
STM study of selenium adsorption on Au(lll) surface

Adsorption of chalcogen atoms on metal surfaces has attracted increasing interest for both the fundamental research and industrial applications. Here, we report a systematic study of selenium (Se) adsorption on Au(lll) at varies substrate temperatures by scanning tunneling microscopy. At room temperature, small Se clusters are randomly dispersed on the surface. Increasing the temperature up to 200 ℃, a well-ordered lattice of Se molecules consisting of 8 Se atoms in ringlike structure is formed. Further increasing the temperature to 250 ℃ gives rise to the formation of Se monolayer with Au(111)-√3×√3 lattices superimposed with a quasi-hexagonal lattice. Desorption of Se atoms rather than the reaction between the Se atoms and the Au substrate occurs if further increasing the temperature. The ordered structures of selenium monolayers could serve as templates for self-assemblies and our findings in this work might provide insightful guild for the epitaxial growth of the two-dimensional transition metal dichalcogenides.
Parametric study of the clustering transition in vibration driven granular gas system

A parametric study of the clustering transition of a vibration-driven granular gas system is performed by simulation. The parameters studied include the global volume fraction of the system, the size of the system, the friction coefficient, and the restitution coefficient among particles and among particle-walls. The periodic boundary and fixed boundary of sidewalls are also checked in the simulation. The simulation results provide us the necessary "heating" time for the system to reach steady state, and the friction term needed to be included in the "cooling" time. A gas-cluster phase diagram obtained through Kolmogorov-Smirnov (K-S) test analysis using similar experimental parameters is given. The influence of the parameters to the transition is then investigated in simulations. This simulation investigation helps us gain understanding which otherwise cannot be obtained by experiment alone, and makes suggestions on the determination of parameters to be chosen in experiments.
Polarization and fundamental sensitivity of ~(39)K (~(133)Cs)–~(85)Rb–~(21)Ne co-magnetometers

The hybrid optical pumping spin exchange relaxation free (HOPSERF) atomic co-magnetometers make ultrahigh sensitivity measurement of inertia achievable. The wall relaxation rate has a big effect on the polarization and fundamental sensitivity for the co-magnetometer, but it is often neglected in the experiments. However, there is almost no work about the systematic analysis of the influence factors on the polarization and the fundamental sensitivity of the HOPSERF co-magnetometers. Here we systematically study the polarization and the fundamental sensitivity of ~(39)K– ~(85)Rb–~(21)Ne and ~(133)Cs–~(85)Rb–~(21)Ne HOPSERF co-magnetometers with low polarization limit and the wall relaxation rate. The ~(21)Ne number density, the power density and wavelength of pump beam will affect the polarization greatly by affecting the pumping rate of the pump beam. We obtain a general formula on the fundamental sensitivity of the HOPSERF co-magnetometers due to shot-noise and the fundamental sensitivity changes with multiple systemic parameters, where the suitable number density of buffer gas and quench gas make the fundamental sensitivity highest. The fundamental sensitivity 7.5355×10~(-11) rad·s~(-1)·Hz~(-1/2) of ~(133)Cs–~(85)Rb–~(21)Ne co-magnetometer is higher than the ultimate theoretical sensitivity 2×10~(-10) rad·s~(-1)·Hz~(-1/2) of K~(–21)Ne co-magnetometer.
Processes underlying the laser photochromic effect in colloidal plasmonic nanoparticle aggregates

We have studied the dynamic and static processes occurring in disordered multiparticle colloidal Ag aggregates with natural structure and affecting their plasmonic absorption spectra under pico- and nanosecond pulsed laser radiations, as well as the physical origin responsible for these processes. We have shown that depending on the duration of the laser pulse, the mechanisms of laser modification of such aggregates can be associated both with changes in the resonant properties of the particles due to their heating and melting (picosecond irradiation mode) and with the particle shifts in the resonant domains of the aggregates (nanosecond pulses) which depend on the wavelength, intensity, and polarization of the radiation. These mechanisms result in formation of a narrow dip in the plasmonic absorption spectrum of the aggregates near the laser radiation wavelength and affect the shape and position of the dip. The effect of polydispersity of nanoparticle aggregates on laser photochromic reaction has been studied.
Electrohydrodynamic behaviors of droplet under a uniform direct current electric field

The electrohydrodynamic behaviors and evolution processes of silicone oil droplet in castor oil under uniform direct current (DC) electric field are visually observed based on a high-speed microscopic platform. Subsequently, the effects of different working conditions, such as electric field strength, droplet size, etc., on droplet behaviors are roundly discussed. It can be found that there are four droplet behavior modes, including Taylor deformation, typical oblique rotation, periodic oscillation, and fracture, which change with the increase of electric field strength. It is also demonstrated that the degree of flat ellipse deformation gets larger under a stronger electric field. Moreover, both of the stronger electric field and smaller droplet size lead to an increase in the rotation angle of the droplet.
Advanced characterization and calculation methods for rechargeable battery materials in multiple scales

The structure–activity relationship of functional materials is an everlasting and desirable research question for material science researchers, where characterization and calculation tools are the keys to deciphering this intricate relationship. Here, we choose rechargeable battery materials as an example and introduce the most representative advanced characterization and calculation methods in four different scales: real space, energy, momentum space, and time. Current research methods to study battery material structure, energy level transition, dispersion relations of phonons and electrons, and time-resolved evolution are reviewed. From different views, various expression forms of structure and electronic structure are presented to understand the reaction processes and electrochemical mechanisms comprehensively in battery systems. According to the summary of the present battery research, the challenges and perspectives of advanced characterization and calculation techniques for the field of rechargeable batteries are further discussed.
Effect of system–reservoir correlations on temperature estimation

In many previous temperature estimation schemes, the temperature of a sample is directly read out from the final steady state of a quantum probe, which is coupled to the sample. However, in these studies, information of correlations between system (the probe) and reservoir (the sample) is usually eliminated, leading the steady state of the probe is a canonical equilibrium state with respect solely to system’s Hamiltonian. To explore the influence of system–reservoir correlations on the estimation precision, we investigate the equilibration dynamics of a spin interacting with a finite temperature bosonic reservoir. By incorporating an intermediate harmonic oscillator or a collective coordinate into the spin, the system–reservoir correlations can be correspondingly encoded in a Gibbs state of an effective Hamilton, which is size consistent with the original bare spin. Extracting information of temperature from this corrected steady state, we find the effect of the systemreservoir correlations on the estimation precision is highly sensitive to the details of the spectral density function of the measured reservoir.
Influence of the Earth’s rotation on measurement of gravitational constant G with the time-of-swing method

In the measurement of the Newtonian gravitational constant G with the time-of-swing method, the influence of the Earth’s rotation has been roughly estimated before, which is far beyond the current experimental precision. Here, we present a more complete theoretical modeling and assessment process. To figure out this effect, we use the relativistic Lagrangian expression to derive the motion equations of the torsion pendulum. With the correlation method and typical parameters, we estimate that the influence of the Earth’s rotation on G measurement is far less than 1 ppm, which may need to be considered in the future high-accuracy experiments of determining the gravitational constant G.
Linear optical approach to supersymmetric dynamics

The concept of supersymmetry developed in particle physics has been applied to various fields of modern physics. In quantum mechanics, the supersymmetric systems refer to the systems involving two supersymmetric partner Hamiltonians, whose energy levels are degeneracy except one of the systems has an extra ground state possibly, and the eigenstates of the partner systems can be mapped onto each other. Recently, an interferometric scheme has been proposed to show this relationship in ultracold atoms [Phys. Rev. A 96 043624 (2017)]. Here this approach is generalized to linear optics for observing the supersymmetric dynamics with photons. The time evolution operator is simulated approximately via Suzuki–Trotter expansion with considering the realization of the kinetic and potential terms separately. The former is realized through the diffraction nature of light and the later is implemented using a phase plate. Additionally, we propose an interferometric approach which can be implemented perfectly using an amplitude alternator to realize the non-unitary operator. The numerical results show that our scheme is universal and can be realized with current technologies.
Collapses-revivals phenomena induced by weak magnetic flux in diamond chain

We investigate the quantum dynamical behaviors of bosons in a diamond chain with weak magnetic flux (WMF), including Landau–Zener tunnelling, Bloch oscillations, localization phenomenon, and collapses-revivals phenomena. We observed that collapses-revivals phenomena can occur in diamond chain with WMF and cannot exist in the strong magnetic flux case as the previous study (Chang N N and Xue J K, 2018, Chin. Phys. B 27 105203). Induced by WMF, the energy band for the system varies from gapless to gapped structure. The position of the extrema of probability amplitude for ground state can also be altered by WMF within a single diamond plaquette. As a consequence, the transitions between different dynamical behaviors of bosons in diamond chain can be manipulated by WMF, depending on its initial configurations.
Macrophage amphiregulin-pericyte TGF-β axis: a novel mechanism of the immune system that contributes to wound repair

The immune system plays a vital role in restoring tissue integrity and function upon injury. Wound healing is a highly dynamic process that involves early inflammatory phase, proliferative phase, and finally the maturation phase. Tissue repair begins with the formation of granulation tissue that contains macrophages to play anti-inflammatory roles. Macrophages within the granulation tissue acquire a spectrum of phase-specific phenotypes affecting fibroblast function, including myofibroblast differentiation, myofibroblast proliferation, and extracellular matrix(ECM) remodeling [1]. Nevertheless, the underlying mechanism that macrophage contributes to the myofibroblast production during tissue repair remains largely unexplored.
Ultra-short plasmonic polarization beam splitter-rotator using a bent directional coupler

We propose and analyze a silicon hybrid plasmonic polarization splitter-rotator with an ultra-short footprint using an asymmetric bent directional coupler on a silicon-on-insulator platform. Benefitting from the large birefringence induced by the bent structure and plasmonic effect, the cross-polarization coupling length is only 5.21 µm. The transverse magnetic to transverse electric polarization conversion efficiency is over 99.9%, with an extinction ratio of 20.6 dB (32.5 dB) for the transverse magnetic (transverse electric) mode at 1.55 µm. Furthermore, the polarization conversion efficiency is higher than 90% while maintaining cross talk below —19 dB within the bandwidth of 80 nm.
Metalens for coaxial double wavelength focusing

We propose a metalens for coaxial double wavelength focusing. One focusing spot is a circular solid spot, and the other focusing spot is a doughnut-shaped spot that is circling the solid spot. The designed metalens was composed of a meta-molecular nanostructured cell array. Each meta-molecular nanostructured cell was divided into four squares. Two slots with exactly the same shape, but usually with the rotation angle measured clockwise from the positive x axis, are etched into the gold film in two diagonally connected squares. Another two slots with the same shape but with the rotation angle measured counter-clockwise from the positive x axis are etched into another two diagonally connected squares in the same cell. The lasers with two different wavelengths are transformed into right-handed and left-handed circularly polarized beams, respectively. The two sets of slots with different azimuthal rotations modulated the phases of incident right-handed and left-handed circularly polarized beams independently. The numerical simulation with finite-difference time-domain (FDTD) software was carried out, and the experimental verification was also implemented. Both the experimental result and the numerical simulation agree well with the theoretical design.
Optimization of optical wireless power transfer using near-infrared laser diodes

We experimentally demonstrated optical wireless power transfer (OWPT) using a near-infrared laser diode (LD) as the optical power transmitter. We considered a photovoltaic (PV) cell and a photodiode (PD) as the optical power receivers. We investigated the characteristics of the LD, PD, and PV cell in order to determine the optimum operating condition from the viewpoint of transfer efficiency. We also experimentally demonstrated a whole system optimization process to maximize the DC-to-DC transfer efficiency of the OWPT. Our experimental results showed that the optimization process can improve the OWPT efficiency by up to 48%.

钝缘蜱传播非洲猪瘟病毒的研究进展及防控建议

非洲猪瘟是由非洲猪瘟病毒(African swine fe- ver virus,ASFV)引起的严重危害养猪业的烈性传染病,历史上在非洲、欧洲的多个国家暴发流行。自2007年传入高加索地区以来,疫情在中亚、东欧等地扩散,并于2018年8月在我国辽宁省沈阳地区首次报道,在不到一年的时间里传播到全国31个省、自治区。目前,我国非洲猪瘟疫情防控形势仍然严峻。国家在加强生猪养殖及调运环节监管、加强生猪及产制品检疫等方面出台了诸多措施,防止AS- FV通过饮食等间接接触方式传播。鉴于ASFV可在媒介蜱体内长期存在,而且可在野猪—钝缘蜱—家猪之间循环传播,我们不能忽视生物媒介——钝缘蜱传播非洲猪瘟的潜在风险。
