In this study we evaluate the oncological and functional results of the largest cohort of patients in China treated by laparoscopic radical prostatectomy （LRP） and with at least 3 years of follow-up. 126 inconsecutive patients （range 56-78 years, median 62.5） who had an LRP were retrospectively analyzed. The mean prostate specific antigen level and Gleason score was 13.4 ng mL^-1 and 6.4, respectively. Twenty-seven patients had unilateral or bilateral nerve preservation and 29 had pelvic lymphadenectomy. Multivariate analysis was used to adjust for differences in clinical and pathological features when comparing the risk for biochemical progression-free survival （bPFS）. Urinary continence was assessed by incontinence questionnaire and erectile function by the Sexual Health Inventory for Men score. The mean operative duration was 250 min and blood loss 354 mL. Five patients received blood transfusion and nine had complications, including rectal injury （two）, ureteral injury （one）, active bleeding （one）, bladder neck stenosis （two）, paralytic ileus （one）, subcutaneous hematoma （one） and port-site hernia （one）. The overall positive surgical margin rate was 20.6% and correlated with pathological stage and Gleason score respectively （P = 0.03, P 〈 0.001 respectively）. All patients had 〉 3 years of follow-up （range 3-6.75 years, mean 4.6, median 4.75）. At 3 years of follow-up, the overall survival rate was 100% and the bPFS was 81.0% in all patients; 124 patients （98.4%） were continent; 22 of 27 patients （81.5%） who underwent nerve preservation retained erectile function. Our series confirms that LRP is an effective, safe and precise technique at Chinese institution.

Alluaudite-type NaMnV2(PO4)3 single crystal was successfully synthesized in the NaCl molten-salt media. The single-crystal diffraction data analysis shows that NaMnV2(PO4)3 crystallizes in monoclinic C2/c space group with a = 12.098(2), b = 12.415(2), c = 6.4543(11)?, β = 114.614(2)°, V = 881.3(3) ?3, Mr = 464.64, Dc = 3.50158 g/cm3, μ(Mo Kα) = 4.046 mm-1, F(000) = 892.4 and Z = 2. The structure consists of MnO6, VO6 octahedra and PO4 tetrahedra, which form a three-dimensional architecture with two sets of large Na+ tunnels. The intercalation/deintercalation properties of NaMnV2(PO4)3 as positive and negative electrodes were tested in sodium batteries.

In software testing, many troublesome faults are caused by interaction of input parameters. If automatic efficient test-case generator（AETG）, in parameter order（IPO） or orthogonal Latin square is used in the software system under test, the whole test set cannot be run completely due to time or budget constraints. In this paper, according to the number of parameter k and their values n, a software system under test can be divided into four types. As for k-2 system, an algorithm was proposed to construct test rases, based on the longitudinal binary string set and method of controlling variables. As for k-n valued parameters whose n was a prime or power of prime, a method of covering array of test sets was designed to construct test sets by taking orthogonal array and derive arrays from orthogonal array and two useful conditions. As for k parameters whose n-value was not all equal, an experience algorithm was presented in this paper. The experimental results show that the size of test sets from the proposed methods is better than that from AETG, IPO, and orthogonal Latin square.

Hydro-chemical characteristics of groundwater and their changes as affected by human activities were studied in the Ejin Sub-Basin of the Inner Mongolia Autonomous Region, China, to understand the groundwater evolution, to identify the predominant geochemical processes taking place along the horizontal groundwater flow path, and to characterize anthropogenic factors affecting the groundwater environment based on previous data. The concentrations of major ions and total dissolved solids （TDS） in the groundwater showed a great variation, with 62.5% of the samples being brackish （TDS ≥ 1 000 mg L^-l）. The groundwater system showed a gradual hydro-chemical zonation composed of Na^＋ -HCO3^-, Na^＋ -Mg^2＋ -SO4 ^2 -Cl^-, and Na^＋ -Cl^-. The relationships among the dissolved species allowed identification of the origin of solutes and the processes that generated the observed water compositions. The dissolution of halite, dolomite, and 2- gypsum explained, in part, the presence of Na^＋, K^＋, Cl^-, SO^4 , and Ca^2＋, but other processes, such as mixing, Na^＋ exchange for Ca^2＋ and Mg^2＋, and calcite precipitation also contributed to the composition of water. Human activity, in particular large-scale water resources development associated with dramatic population growth in the last 50 years, has led to tremendous changes in the groundwater regime, which reflected in surface water runoff change, decline of groundwater table and degeneration of surface water and groundwater quality. Solving these largely anthropogenic problems requires concerted, massive and long-term efforts.

There exists a large local relative orbital angular momentum between produced partons along the direction opposite to the reaction plane in the early stage of non-central heavy-ion collisions. This initial local orbital angular momentum can lead to quark polarization along the same direction due to spin-orbital coupling in QCD. We present the quark polarization by using hard thermal loop gluon propagator for quark-quark scattering in quark-gluon plasma and compare it with the result obtained from the static potential model.

The morphological characteristics of small-scale bedforms were measured by means of an acoustic profiling sonar on the Dafeng tidal flat, jiangsu, in 2009, and in the Jiulong Estuary, Xiamen, in 2010, respectively. The ＂multi-threshold value＂ method was utilized to reveal the morphological undulations along which bedforms were present. Analyses of the datasets obtained show that：（1） sand ripples can have irregular shapes, and （2） changes in bedform morphology are small within a single tidal cycle but may be significant over several tidal cycles. Fractal and variogram analyses of the seabed roughness revealed the existence of a significant relationship between current speed and the fractal dimension of the seabed roughness. As current speed increases, seabed roughness increases with a trend of smaller-scale bottom structures being replaced by larger-scale structures. Furthermore, the surface of the larger-scale bottom structures can either become smooth due to the absence of smaller-scale features or become rougher due to the presence of superimposed smaller-scale structures.

状态空间爆炸问题是模型检测的最大障碍.从余归纳(特别是余代数)的角度研究了这个问题.用余归纳的方法证明:(1)对于任意给定的一类Kripke结构(记为K),在互模拟等价意义下K中最小Kripke结构(记为K0)的存在唯一性.K0描述了K中所有Kripke结构的行为而且没有冗余的状态;(2)对于任意的M∈K(M可能包含无穷多个状态),在互模拟等价意义下的相对于(M且基于K0)的最小Kripke结构(记为KM)的存在唯一性.由此提出一种求解KM的算法,并用Ocaml予以简单实现.其应用之一在于可以用状态空间更小的KM代替M进行模型检测.该方法可自然地推广到基于其他类型函子的余代数结构.

We theoretically investigate the spin resolved Friedel oscillation （FO） and quasiparticle interference （QPI） in graphene induced by an Anderson *** the impurity becomes magnetic,the resulted FO becomes spin dependent,which gives rise to a local magnetic moment oscillation with an envelop decaying as r-2in real space in the doping ***,at half filling,the electron density and local magnetic moment will not oscillate but decay as *** spin resolved FO has both sublattice and spin ***,the local magnetic moment decay at half filling only occurs at one sublattice of graphene,which is quite like the phenomenon observed in the STM experiment (***ález-Herrero et al.,Science 352,437 （2016）).We further give an analytic formula about such spin dependent FO based on the stationary phase ***,we study the interference of quasiparticles around the magnetic impurity by calculating the spin dependent Fourier-transformed local density of states （FT-LDOS）.Our work gives a comprehensive understanding about the local magnetic moment oscillation around an Anderson impurity on graphene.
