description: A series of new diorganotin(IV) complexes of the type [R′2SnL] have been synthesized by the reaction of 2-benzoyl-1H-indene-1,3(2H)-dione Schiff bases with R′2SnCl2, (R′ = Me, Et, n-Bu, Ph) in 1:1 molar ratio. These complexes were well characterized by IR, 1H, 13C, 119Sn NMR, XRD and mass spectrometry techniques. In the search for biologically more effective antimicrobial agents, all the synthesized ligands and organotin complexes were evaluated for their in vitro antimicrobial activities against two Gram-positive and two Gram-negative bacteria, and three fungal strains by serial dilution method. The results of spectral data revealed that the complexes formed were pentacoordinated with tridentate ligands which coordinated through azomethine N and carbonyl O and carboxylate O to the central tin atom. The ligands on coordination with tin metal showed a discernible augmentation in biocidal activity, however, the Ph and Bu complexes were found to be more intoxicating. The results revealed that the synthesized complexes were more noxious toward Gram-positive strains as compared to Gram-negative strains which may be attributed to the presence of an outer lipid membrane of lipopolysaccharides. Further, QSAR studies and DNA binding studies were performed which supported that bioactivity gets enhanced on complexation.

description: In the framework of the variational principle the canonical variables describing ideal magnetohydrodynamic (MHD) flows of general type (i.e., with spatially varying entropy and nonzero values of all topological invariants) are introduced. The corresponding complete velocity representation enables us not only to describe the general type flows in terms of single-valued functions, but also to solve the intriguing problem of the ``missing'' MHD integrals of motion. The set of hitherto known MHD local invariants and integrals of motion appears to be incomplete: for the vanishing magnetic field it does not reduce to the set of the conventional hydrodynamic invariants. And if the MHD analogs of the vorticity and helicity were discussed earlier for the particular cases, the analog of Ertel invariant has been so far unknown. It is found that on the basis of the new invariants introduced a wide set of high-order invariants can be constructed. The new invariants are relevant both for the deeper insight into the problem of the topological structure of the MHD flows as a whole and for the examination of the stability problems. The additional advantage of the proposed approach is that it enables one to deal with discontinuous flows, including all types of possible breaks.

description: Using partial identification methods and data from the PSID, we analyze the causal transmission of food security across generations. Food security rates are positively correlated across generations; food security rates in 2015 are 20 points higher for respondents who grew up in households that were secure in 1999 than those growing up in food insecure households. Despite these strong associations, the intergenerational effect of growing up in a food secure household remains uncertain. . Assessing the degree of intergenerational transmission of food security is complicated by unobserved factors (e.g., human capital, health issues) that jointly influence whether a child resides in a food secure household and, subsequently, whether likely to be food secure as a young adult. Identifying causal transmission across generations requires addressing this important selection problem. In light of the ambiguities created by the selection problem, a number of alternative assumptions and estimates are presented. While under the weakest assumptions very little can be inferred, results derived under strong but plausible assumptions provide evidence that growing up in a food insecure household increases the probability of being food insecure as a young adult.

description: The energy spectra and wavefunctions of up to 14 interacting quasielectrons (QE's) in the Laughlin nu=1/3 fractional quantum Hall (FQH) state are investigated using exact numerical diagonalization. It is shown that at sufficiently high density the QE's form pairs or larger clusters. This behavior, opposite to Laughlin correlations, invalidates the (sometimes invoked) reapplication of the composite fermion picture to the individual QE's. The series of finite-size incompressible ground states are identified at the QE filling factors nu_QE=1/2, 1/3, 2/3, corresponding to the electron fillings nu=3/8, 4/11, 5/13. The equivalent quasihole (QH) states occur at nu_QH=1/4, 1/5, 2/7, corresponding to nu=3/10, 4/13, 5/17. All these six novel FQH states were recently discovered experimentally. Detailed analysis indicates that QE or QH correlations in these states are different from those of well-known FQH electron states (e.g., Laughlin or Moore-Read states), leaving the origin of their incompressibility uncertain. Halperin's idea of Laughlin states of QP pairs is also explored, but is does not seem adequate.

description: Agricultural insurance has been implemented for more than ten years in China. It is of great significance to analyse the impact of agricultural insurance on agricultural production in order to further design and promote innovative agricultural insurance. From a national perspective, 31 provinces in China are divided into four agricultural insurance development regions according to the level of economic development and agricultural development by cluster analysis. Then panel data model is used to analyse the impact of national and four regions agricultural insurance on agricultural production value. The empirical results show that the gross value of agricultural production is positively and significantly affected by agricultural insurance, planting area, loss ratio, and human capital.

description: We consider the production of open charm in heavy ion collisions in the framework of the Color Glass Condensate. In the central rapidity region at RHIC, for the charm quark yield we expect N(coll) (number of collisions) scaling in the absence of final-state effects. At higher energies, or forward rapidities at RHIC, the saturation scale exceeds the charm quark mass; we find that this results in the approximate N(part) (number of participants) scaling of charm production in AA collisions and N(part)^A scaling in p(d)A collisions, similarly to the production of high pT gluons discussed earlier. We also show that the saturation phenomenon makes spectra harder as compared to the naive parton model approach. We then discuss the energy loss of charm quarks in hot and cold media and argue that the hardness of the spectrum implies very slow dependence of the quenching factor on pT.

 Type species. Hamataliwa grisea Keyserling, 1887, by monotypy.
 Diagnosis. Hamataliwa can be distinguished from the closely related genus Oxyopes by the following characters: female epigynum with a shallow median depression surrounded by a semicircular or U­shaped, heavily sclerotized rim (Figs. 2, 7, 12, 17, 22); copulatory ducts usually short, spermathecae round or oval (Figs. 3, 8, 13, 18, 23); embolus of male palp forming a characteristic twist or loop near the base; edge of cymbium with a basal outgrowth, finger­like in lateral view (Figs. 4–5, 9–10, 14–15, 19–20, 24–25). Copulatory ducts and spermathecae are always wrapped with glue­like materials after copulation (Figs. 3, 8, 13), which is not detected in Oxyopes.
 Description. See general characteristics of the genus described by Brady (1964).

description: In this paper, the structural, electronic and magnetic properties of Zinc-blende Ga1-xVxSb compounds, with x from dilute doping situation to extreme doping limiting, were systematically investigated by first-principles calculations. V atoms prefer to substitute the Ga atoms and the formation energy is lower in Sb-rich than Ga-rich growth condition. Meantime, the SbGa antisite defects can effectively decrease the energy barrier of substitution process, from 0.85 eV to 0.53 eV. The diffusion of V atom in GaSb lattice is through meta-stable interstitial sites with an energy barrier of 0.6 eV. At a low V concentration x = 0.0625, V atoms prefer a homogeneous distribution and an antiferromagnetic coupling among them. However, starting from x = 0.5, the magnetic coupling among V atoms changes to be ferromagnetic, due to enhanced superexchange interaction between eg and t2g states of neighbouring V atoms. At the extreme limiting of x = 1.00, we found that Zinc-blende VSb as well as its analogs VAs and VP are intrinsic ferromagneitc semiconductors, with a large change of light absorption at the curie temperature. These results indicate that Ga1-xVxSb compounds can provide a platform to design the new electronic, spintronic and optoelectronic devices.

description: We examine how soda sales changed due to the campaign attention and election out- come of a local excise tax on sugar-sweetened beverages (SSB), most commonly referred to as a soda tax. Using panel data of beverage sales from university retailers in Berkeley, California, we estimate that soda purchases relative to control beverages significantly dropped immediately after the election, months before the tax was implemented in the city of Berkeley or on campus. Supplemental scanner data from off campus drug stores reveal this result is not unique to the university setting. Our findings suggest soda tax media coverage and election outcomes can have larger effects on purchasing behavior than the tax itself.

In order to evaluate their antibacterial potential, the antibacterial assay of synthesized compounds 6a–j was performed against MTCC strains, wherein compounds 6d (3-(4-methyl-5-(4-(((4-nitrophenyl)amino)methyl)-5-thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)thiazol-2-yl)-2-phenylquinazolin-4(3H)-one) (Escherichia coli, MIC = 100 µg mL−1) and 6e (3-(5-(4-(((2-chlorophenyl)amino)methyl)-5-thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)-4-methylthiazol-2-yl)-2-phenylquinazolin-4(3H)-one) (E. coli, MIC = 62.5 µg mL−1) were most active against Gram-negative bacteria while compound 6f (3-(5-(4-(((4-chlorophenyl)amino)methyl)-5-thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)-4-methylthiazol-2-yl)-2-phenylquinazolin-4(3H)-one) (Staphylococcus aureus, MIC = 50 µg mL−1) was most active against Gram-positive bacteria. Furthermore, molecular docking simulation was performed to determine the probable binding mode and affinity of the synthesized compounds toward bacterial DNA gyrase. The preliminary results pave the way for further designing the thiazole based 1,3,4-oxadiazoles heterocycles for enhancing their potency as antibacterial agents.

description: We investigate the relationship between visual attention and attendence with the rate of "preference reversals" in a discrete choice experiment (DCE) that employed eyetracking. We nd that visual attention and attendance, counter to our initial expectations, is positively related to the rate of preference reversal. Our results indicate that moderately low levels of visual attention should not be used as a way of identifying individuals with low levels of engagement, nor should preference reversals necessarily be assumed to indicate low levels of participant engagement. We nd that those reversing preferences do not substantively di¤er from the rest of the population in terms of their underlying preferences. Rather, these respondents spend longer looking at tasks that are similar in terms of utility, so more complex, and as a result these respondents are more uncertain of the choice to make.

description: We discuss the possibility that the recent detection of 511 keV gamma rays from the galactic bulge, as observed by INTEGRAL, can be naturally explained by the supermassive very dense droplets (strangelets) of dark matter. These droplets are assumed to be made of ordinary light quarks (or antiquarks) condensed in non-hadronic color superconducting phase. The droplets can carry electrons (or positrons) in the bulk or/and on the surface. The e^+e^- annihilation events take place due to the collisions of electrons from the visible matter with positrons from dark matter droplets which may result in the bright 511 KeV gamma-ray line from the bulge of the Galaxy.

In all three coordination compounds, the metal ion is in square planar geometry Na[Ni(TBNCA)·OAc], [Pd(TBNCA)·dmso] and [Pt(TBNCA)·dmso] are mononuclear complexes. The structure of H2TBNCA was elucidated by X-ray diffraction analysis. In the broth dilution method, Na[Ni(TBNCA)·OAc] exhibited significant antibacterial activity against Escherichia coli and Staphylococcus aureus with minimum inhibition concentration (MIC) of 12.5 and 6.25 µg mL−1, respectively. [Pt(TBNCA)·dmso] also showed antibacterial activities against E. coli and S. aureus with MIC value of 25 µg mL−1, while [Pd(TBNCA)·dmso] showed lesser activity with MIC values in the range of 50–100 µg mL−1. In the disk diffusion method, the complexes showed significant antibacterial properties against both E. coli and S. aureus, whereas the ligand did not show any significant activity.

description: We propose a systematic method to construct quasi-solvable quantum many-body systems having permutation symmetry. By the introduction of elementary symmetric polynomials and suitable choice of a solvable sector, the algebraic structure of sl(M+1) naturally emerges. The procedure to solve the canonical-form condition for the two-body problem is presented in detail. It is shown that the resulting two-body quasi-solvable model can be uniquely generalized to the M-body system for arbitrary M under the consideration of the GL(2,K) symmetry. An intimate relation between quantum solvability and supersymmetry is found. With the aid of the GL(2,K) symmetry, we classify the obtained quasi-solvable quantum many-body systems. It turns out that there are essentially five inequivalent models of Inozemtsev type. Furthermore, we discuss the possibility of including M-body (M>=3) interaction terms without destroying the quasi-solvability.

description: Droughts are expected to become more frequent and more severe under all climate change scenarios. They are predicted, in turn, to result in a significant increase in the associated cost to the agricultural sector in New Zealand. This paper explores how drought hazards affected agricultural productivity and economic performance for different sectors (sheep and beef farming and dairy farming) between 2007 and 2016. We combine agricultural and financial farm-level panel data from Statistics New Zealand’s Longitudinal Business Database (LBD) with the drought index produced by the National Institute of Water and Atmospheric Research (NIWA). We estimate a set of fixed-effects panel regressions and find that drought events have negative impact on the agricultural productivity across all sectors, where the most vulnerable sector is dairy farming. Dairy sector’s operating profit is significantly reduced through increasing in operating cost due to proving feed for livestock during drought events. Results also show that droughts affect farms’ financial indicators such as their interest coverage, return on capital, business equity and debt to income ratio.

description: The problem of natural selection in dispersal-structured populations consisting of individuals characterized by different diffusion coefficients is studied. The competition between the organisms is taken into account through the assumption that the reproduction and/or death probability of an individual is influenced by the number of other individuals within a neighborhood with radius R. It is observed that for a wide range of parameters the competition advantage is given to the individuals whose motion is characterized by intermediate values of diffusion coefficient, instead of the most or least motile ones. The optimal level of the dispersal is determined by the interplay between various factors such as cluster formation, temporal fluctuations, initial conditions, and carrying capacity of the system. The dynamics and the time evolution of the system are investigated in detail revealing the winning mechanism and process of the natural selection in such dispersal-structured populations. Furthermore, the rescaling of the results is discussed for different values of the interaction radius R of the organisms.

description: The global food system, from fertilizer production to food packaging, is responsible for one-third of all human-caused greenhouse gas emissions. On average, carbon footprint represents more than 50% of the total ecological footprint in the world. Carbon footprint is said to be a widely accepted indicator of GHG intensity, originating from different economic activities. Due to its important role in raising awareness of global warming, scientists and policymakers also use it as a management tool. However, the application of carbon footprint on the agricultural sector is still limited in the literature. The aim of the paper is to explore what agriculture-specific factors influence the carbon footprint at a global level. This research investigates the determinants of the carbon footprint on a global sample, considering the role of agriculture and trade for a period of 1961-2013. Data are derived from the Global Footprint Network and the World Bank databases. The sample includes a panel dataset of 133 countries and 53 years’ period. A feasible generalized least squares estimator is applied to the sample in order to estimate the regression model, along with panel tests. Results show that carbon footprint is stimulated by economic development and agricultural production (arable land, agricultural machinery, fertilizer use). Furthermore, agricultural trade has a positive impact on the carbon footprint. By contrast, the growth of carbon footprint is negatively related to the higher share of rural population and agricultural development.

description: China is urbanizing at an unprecedented way. Along with the continuous urban expansion, comes out the urban conflicts between supply and demand and substantive value capture between rural and urban areas. The purpose of this study is to examine whether the open access of rural construction land market can mitigate the urban conflicts above. Taking Nanhai and Deqing, the typical areas of rural construction land transaction, as our study area, this work has gathered data both from transaction record and field investigation, estimated the supply and demand function and calculated the optimal supply allocation between governments and collectives based on the theoretical analysis of duopoly market and cournotnash equlibrum. The results indicates that (1) the admission for rural construction land market shifts the construction land market from monopoly to duopoly can improve the market efficiency theoretically.(2) the rural construction land market mitigates the constraint of urban conflict by providing more construction lands and sharing the land incremental value to rural areas.(3) there exists a substitution relationship between government and collective at cournot-nash equilibrium;(4) the local government with land coupon and rural-urban land transactions can occupy greater market share.

description: The study examined the production technologies and productive performance of smallholder beef production systems to determine the levels of technical inefficiency in the agricultural districts of Botswana. The analysis draws on data from 26 districts of Botswana for the period of 2006-2014 to estimate latent class stochastic frontiers in which the technological class to which the agricultural district belongs is determined within the model. To enable efficiency comparisons between agricultural districts across these technological classes, a meta-frontier that encompasses all the class frontiers is estimated. Components of efficiency drivers are embedded in this estimation to explain agricultural districts technical inefficiency with respect to their respective class frontiers. Results show that beef production efficiency is positively associated with the rate of formal education and negatively related with an increase in proportion of exotic breeds, high mortality and low offtake rates, indicating the presence of considerable scope for animal husbandry improvement. The mean technical efficiency scores for beef production between 2006 and 2014 for agricultural districts in class one is 18 % whereas it is 13 % for agricultural districts in class two, implying high potential to improve beef production using the same level of agricultural inputs through efficiency-enhancing investments.

description: The planned SIS100 heavy ion synchrotron at the GSI Helmholtzzentrum für Schwerionenforschung will possess twenty ferrite accelerating cavities in its final stage of extension. As at injection and at flat top during slow extraction of the planned acceleration cycles the RF voltage will be relatively low, not all cavities will be active in this part of operation. It is important to analyse the impact of the inactive cavities on the overall RF voltage and subsequently their implication on the longitudinal particle dynamics. Classical approaches for reducing the beam impedance consist of active detuning of the cavities to pre-described parking frequencies. The fact that two out of ten buckets have to stay empty in all SIS100 scenarios is of particular interest as additional frequency components appear in the excitatory beam current, which have to be considered when the cavity is detuned. Therefore multi-cavity particle tracking simulations, consisting of twenty cavities and their attached LLRF control systems, are carried out in order to analyse different possibilities to minimize the impact on the beam dynamics and emittance growth.

description: In a complex disease such as tuberculosis, the evidence for the disease and its evolution may be present in multiple modalities such as clinical, genomic, or imaging data. Effective patient-tailored outcome prediction and therapeutic guidance will require fusing evidence from these modalities. Such multimodal fusion is difficult since the evidence for the disease may not be uniform across all modalities, not all modality features may be relevant, or not all modalities may be present for all patients. All these nuances make simple methods of early, late, or intermediate fusion of features inadequate for outcome prediction. In this paper, we present a novel fusion framework using multiplexed graphs and derive a new graph neural network for learning from such graphs. Specifically, the framework allows modalities to be represented through their targeted encodings, and models their relationship explicitly via multiplexed graphs derived from salient features in a combined latent space. We present results that show that our proposed method outperforms state-of-the-art methods of fusing modalities for multi-outcome prediction on a large Tuberculosis (TB) dataset.

description: With a large-scale household survey data of maize farmers in China, this study examines how farmers perceptions of drought severity influence their adaptation strategies using endogenous switching probit models. Both ex ante and ex post adaptations are modeled. The empirical results first suggest that the impacts of farmers perceptions of drought severity on their ex ante and ex post adaptive behaviors are different. A farmer perceiving an increasing trend of drought severity has a 7.3% higher probability to use drought tolerant variety as ex ante adaptation, while a 4.8% higher probability of irrigation than those of other farmers. On average, farmers who use drought tolerant maize variety have a 18% lower probability to irrigate, which indicates that the ex-ante adaptation, using drought tolerant maize variety, reduces the need to irrigate as ex-post reaction to drought. Our results lend more support to the importance of farmers perceptions of drought severity to their adaptations. Our results also the importance in considering both ex ante and ex post adaptations in policy making.

description: We combine the recently published CIZA galaxy cluster catalogue with the XBACs cluster sample to produce the first all-sky catalogue of X-ray clusters in order to examine the origins of the Local Group's peculiar velocity without the use of reconstruction methods to fill the traditional Zone of Avoidance. The advantages of this approach are (i) X-ray emitting clusters tend to trace the deepest potential wells and therefore have the greatest effect on the dynamics of the Local Group and (ii) our all-sky sample provides data for nearly a quarter of the sky that is largely incomplete in optical cluster catalogues. We find that the direction of the Local Group's peculiar velocity is well aligned with the CMB as early as the Great Attractor region 40 h^-1 Mpc away, but that the amplitude of its dipole motion is largely set between 140 and 160 h^-1 Mpc. Unlike previous studies using galaxy samples, we find that without Virgo included, roughly ~70% of our dipole signal comes from mass concentrations at large distances (>60 h^-1 Mpc) and does not flatten, indicating isotropy in the cluster distribution, until at least 160 h^-1 Mpc. We also present a detailed discussion of our dipole profile, linking observed features to the structures and superclusters that produce them. We find that most of the dipole signal can be attributed to the Shapley supercluster centered at about 150 h^-1 Mpc and a handful of very massive individual clusters, some of which are newly discovered and lie well in the Zone of Avoidance.

description: Rice farming remains an important undertaking in Asia and Africa due to its important role in maintaining essential food supply. Rice ranks second to maize in providing more than one-fifth of the calories consumed worldwide. In Kenya, rice is an important food crop and cash crop. A survey of 773 farmers was undertaken in Mwea, West Kano, Ahero and Bunyala rice growing regions to investigate the technical efficiency and technology gap ratios. The meta-frontier estimates indicate that the technical efficiency of Mwea, West Kano, Ahero and Bunyala was 0.556, 0.475, 0.402 and 0.45 respectively. The regional efficiencies indicate that the technical efficiency of Mwea, WestKano, Ahero and Bunyala was 0.557, 0.784, 0.833 and 0.937 respectively. Thus, the technology gap ratio was 0.998, 0.605, 0.482 and 0.48 for Mwea, West Kano, Ahero and Bunyala respectively. The results thus suggest that a narrow gap existed between the region and the meta-frontier results for Mwea, while a wider gap existed for West Kano, Ahero and Bunyala implying that Mwea farmers were more technically efficient than farmers in the other schemes. Using the fractional regression models the determinants of efficiency were found to be age, farmer s gender, humidity, rainfall, temperature and adopting technologies. Acknowledgement :

description: The structure of Yukawa coupling matrices is investigated in type IIA T^6/(Z_2 x Z_2) orientifold models with intersecting D-branes. Yukawa coupling matrices are difficult to be realistic in the conventional models in which the generation structure emerges by the multiple intersection of D-branes in the factorized T^6 = T^2 x T^2 x T^2. We study the new type of flavor structure, where Yukawa couplings are dynamically generated, and show this type of models lead to nontrivial structures of Yukawa coupling matrices, which can be realistic.

description: We analyze the different fates of the circumgalactic medium (CGM) in FIRE-2 cosmological simulations, focusing on the redshifts z=0.25 and z=2 representative of recent surveys. Our analysis includes 21 zoom-in simulations covering the halo mass range Mh(z=0) ~ 10^10 - 10^12 Msun. We analyze both where the gas ends up after first leaving the CGM (its "proximate" fate), as well as its location at z=0 (its "ultimate" fate). Of the CGM at z=2, about half is found in the ISM or stars of the central galaxy by z=0 in Mh(z=2) ~ 5e11 Msun halos, but most of the CGM in lower-mass halos ends up in the IGM. This is so even though most of the CGM in M_h(z=2) ~ 5e10 Msun halos first accretes onto the central galaxy before being ejected into the IGM. On the other hand, most of the CGM mass at z=0.25 remains in the CGM by z=0 at all halo masses analyzed. Of the CGM gas that subsequently accretes onto the central galaxy in the progenitors of Mh(z=0) ~10^12 Msun halos, most of it is cool (T~10^4 K) at z=2 but hot (~Tvir) at z=0.25, consistent with the expected transition from cold mode to hot mode accretion. Despite the transition in accretion mode, at both z=0.25 and z=2 >~80% of the cool gas in Mh >~ 10^11 Msun halos will accrete onto a galaxy. We find that the metallicity of CGM gas is typically a poor predictor of both its proximate and ultimate fates. This is because there is in general little correlation between the origin of CGM gas and its fate owing to substantial mixing while in the CGM.
