From April to July 2018,a data sample at the peak energy of the T(4 S) resonance was collected with the Belle Ⅱ detector at the SuperKEKB electron-positron collider.This is the first data sample of the Belle Ⅱ experiment.Using Bhabha and digamma events,we measure the integrated luminosity of the data sample to be(496.3±0.3±3.0) pb-1,where the first uncertainty is statistical and the second is systematic.This work provides a basis for future luminosity measurements at Belle Ⅱ.

The product of the ∧0/b （-B/0） differential production cross-section and the branching fraction of the decay ∧0/b→ J/ψ pK-（-B/0→ J/ψ-K＊（892）0）is measured as a function of the beauty hadron transverse momentum, PT, and rapidity, y. The kinematic region of the measurements is pT〈20 GeV/c and 2.0 〈g〈4.5.The measurements use a data sample corresponding to an integrated luminosity of 3fb-1 collected by the LHCb detector in pp collisions at centre-of-mass energies √s=7 TeV in 2011 and √s=8 TeV in 2012. Based on previous LHCb results of the fragmentation fraction ratio,f∧0/b/fd,the branching fraction of the decay ∧0/b→ J/ψ pK-is measured to be B（∧0/b→ J/ψ pK-）=（3.17±0.04±0.07±0.34＋0.45/-0.28）×10-4,where the first uncertainty is statistical, the second is systematic, the third is due to the uncertainty on the branching fraction of the decay -B/0 →J/ψ-K＊（892）0,and the fourth is due to the knowledge of f∧0/b/fd.The sum of the asymmetries in the production and decay between ∧0/b and ∧0/bis also measured as a function of PT and y.The previously published branching fraction of ∧0/b→ J/ψ pπ-,relative to that of ∧0/b→ J/ψ pK-,is updated. The branching fractions of ∧0/b→P＋c（→ J/ψp）K-are determined.

The main morphological features of fungi representing different evolutionary lines are discussed.Environmental situations which stimulate morphological changes are regarded.it is suggested to define ecological significance of fungal morphological characters,dividing them to the ecologically inert(the main characters determining evolutionary line) and ecologically active-characters which submerged to the changes with the changing of environmental conditions.Two main strategies for fungi in nature are described:raising competitive ability to win conquer for substratum,for the place in ecosystem,and the second way for less competitive species-to adapt to more stressful natural conditions and to occupy ecological niches becoming free.Some examples of analysis of adaptation to substrata and climatic zones by fungi are shown.

The results of numerical simulation of the mosaic embedding iron ore sintering （MEBiOS） process according to the model presented in the first part of the study are introduced. The main objective of the second part is the elucidation of key factors influencing the process efficiency, particularly the sintering completeness, velocity of the heat wave propagation and maximum temperature achievable in the pellet during the wave propagation. Numerical results reveal that the mass fraction of coal, diameter of coal particles and air inlet velocity are of prime importance in determining efficiency of the MEBiOS sintering process.

The conceptual design of the capacitive energy storage intended for operation in laboratory conditions is considered. This capacitive energy storage includes the capacitor cells of 200 kJ stored energy, each incorporating one self-healing high-energy-density capacitor, one semiconducting switch unit on the basis of Light Triggered Thyristors(LTT) and the pulse diodes, as well as the toroid inductor. Power supply of the capacitive energy storage is provided by high voltage(HV) 3 x 10 kV, 50 Hz industrial electrical network, using the HV power transformer and phase-controlled rectifier. Special design for the capacitor cell and the module of capacitor cells is proposed, which provides easy access to all components of the capacitor cells during operation and maintenance. Control system of the capacitive energy system has a hierarchic structure and includes programmable logic controller(PLC), programmer for non-synchronous triggering of capacitor cells discharges and data acquisition system.

Fiber lasers are a paradigm of dissipative systems,which distinguish themselves from a Hamilton system where energy is conservative.Consequently,pulses generated in a fiber laser are always accompanied by the continuous wave(CW).Under certain hypothesis,pulses generated in a fiber laser can be considered as a soliton,a product of a Hamilton system.Therefore,all the descriptions of solitons of a fiber laser are approximate.Coexistence of solitons and the CW from a fiber laser prevents unveiling of real nonlinear dynamics in fiber lasers,such as soliton interactions.Pulse behavior in a fiber laser can be represented by the state of single pulse,the state of period doubling of single pulse,the states of two pulses either tightly bound or loosely distributed,the states of three pulses,and various combinations of the above-mentioned states.Recently,soliton distillation was proposed and numerically demonstrated based on the nonlinear Fourier transform(NFT)[J.Lightwave Technol.39,2542(2021)].Solitons can be separated from the coherent CW background.Therefore,it is feasible to isolate solitons from CW background in a fiber laser.Here,we applied the NFT to various pulses generated in a fiber laser,including single pulse,single pulse in period doubling,different double pulses,and multiple pulses.Furthermore,with the approach of soliton distillation,the corresponding pure solitons of those pulses are reconstructed.Simulation results suggest that the NFT can be used to identify soliton dynamics excluding CW influence in a fiber laser,which paves a new way for uncovering real soliton interaction in nonlinear systems.

The study represents analysis of average diurnal,seasonal,annual atmosphere and surface temperatures and their amplitudes.Global Mars Climate Data Base（GMCDB） founded on the climate modeling and Global Circulation Model（GCM） has been used for evaluation of the temporal and spatial inconstancy of the surface atmosphere and radiation-thermal balance for the high latitude areas of Mars.The work focused on the summary of sample processed maps dealing with the distribution of main components of the surface radiation-thermal balance and a number of parameters having an influence on it along the meridian and latitudinal strike for the high latitude areas where intensive manifestation of frost cracking processes were marked.These processes include complete radiation-heat flux to the surface and its separate part for iR spectrum;heat flow from the surface and its component for iR spectrum;albedo and emissivity coefficient of the surface;atmosphere pressure and density for the heights from 5 m to 3 km above the surface;in near-surface layers of atmosphere towards the latitude and longitude directions.An attention was paid to analysis of the temperature conditions on the surface and near-surface atmospheric layers.in particular,next features are characteristic for the dynamics of seasonal surface temperature:temperature comes up to the highest values at the end of summer that leads to the warm autumn.This is changed into the strict ceasing of the average winter temperature with the different distribution of the lowest values on selected areas.The dynamic of temperature differentiation within the meridian and latitudinal range shows the character of the temperature changes and its relation to the location and the forming time of the temperature mode.Variability of average diurnal,seasonal,annual atmosphere and surface temperatures and their amplitudes were evaluated.These are characterized by peculiar zoning distribution on Mars.

为了在机翼设计的初始阶段,给出比较准确的结构质量估算,在承载因子的基础上,结合变满应力理论与有限元技术,提出了一种采用承载因子系数进行质量估算的方法,并给出了其在桁条蒙皮式机翼结构中的应用方案.以5种外形相同但内部载荷传递结构不同的三角机翼为例,质量估算结果表明:在机翼设计的初始阶段,此方法不仅可以估算和比较不同承载结构方案的效率,同时也能预测出其相对更为准确的结构质量.
