description: It has been widely acknowledged that the construction industry is a very strong and viable contributor to the economic growth of any nation. To this end, the Nigerian construction industry plays an important role in meeting the needs of the nation’s infrastructural and economic development; thus, making it one of the main economic indicators that determine the growth of the Nigerian economy. However, previous studies have observed a general decline in quality performance of construction projects in the Nigerian construction industry due to its poor quality cultural practices; thus, leading to the prevalence of abandoned projects, high maintenance cost, loss of lives due to building collapse, clients’ dissatisfaction, and low competitiveness. The low quality of construction projects has also resulted in the dominance of foreign-based companies over the local contractors in Nigeria in terms of contract procurement and quality delivery.

description: In a recent letter Blumberg and collaborators claim that a non-monotonic $d_{x^2-y^2}$ form for the superconducting order parameter is required to explain their Raman scattering measurements in Nd$_{2-x}$Ce$_x$CuO$_4$ . In this comment we show with a simple model calculation that the basis for this conclusion is insufficient. The proposed functional dependence of the gap is neither consistent with their measured spectra nor compatible with other experimental results. Therefore the issue of the superconduing gap in electron-doped systems cannot be considered solved by now.

description: We report $^{75}$As-NMR results for CrAs under pressure, which shows superconductivity adjoining a helimagnetically ordered state. We successfully evaluated the Knight shift from the spectrum, which is strongly affected by the quadrupole interaction. The Knight shift shows the remarkable feature that the uniform spin susceptibility increases toward low temperatures in the paramagnetic state. This is in sharp contrast to CrAs at ambient pressure, and also to cuprates and Fe pnictides, where antiferromagnetic correlations are dominant. Superconductivity emerges in CrAs under unique magnetic correlations, which probably originate in the three-dimensional zigzag structure of its nonsymmorphic symmetry.

Prediction of an exotic state around 4240 MeV with $J^{PC}=1^{-+}$ as C-parity partner of Y(4260) in molecular picture

description: The possibility of the Y(4260) being the molecular state of $D\bar D_1(2420)+\mathrm{c.c.}$ is investigated in the one boson exchange model. It turns out that the potential of $J^{PC}=1^{--}$ state formed by $D\bar D_1(2420)+\mathrm{c.c.}$ is attractive and strong enough to bind them together when the momentum cutoff $Λ\gtrsim 1.4$ GeV. To produce the Y(4260) with correct binding energy, we need $Λ\approx 2.1$ GeV. Besides, $D\bar D_1(2420)+\mathrm{c.c.}$ can also form a state with exotic quantum numbers, $J^{PC}=1^{-+}$, and its potential similar with that of the $J^{PC}=1^{--}$ state. Therefore, an exotic state with mass around 4240 MeV (called $η_{c1}(4240)$) is predicted to exist. Our estimation of the mass of the $J^{PC}=1^{-+}$ state in charmonium region is in agreement with those predicted by the chiral quark model and the lattice QCD. The possible decay modes and their relative widths are estimated and the results suggest that this exotic state can be searched for in $ηη_c$ and $ηχ_{c1}$ channels.

 Material examined: BRAZIL: São Paulo State, Parque Estadual Intervales, gruta Paiva, CDC trap, holotype male, 14.viii.2001, E. Galati (MZUSP). Other material as in Andersen et al. (2010: 53).
 Diagnostic characters: The species differ from P. forcipata by having median volsella nearly as long as superior volsella, superior volsella with basal anterior projection carrying 2–4 setae (always?), gonostylus bilobed with secondary lobe adpressed to gonostylus, and apodeme lobe apparently with only two weak wrinkles.
 The species is described in detail in Andersen et al. (2010: 53). The species may be a variety of P. forcipata. The main differences consist in the longer median volsella, the more clearly two-lobed partly fused gonostylus, and the anterobasal projection of the superior volsella. It is known from two localities in São Paulo State, Brazil.

description: In order to separate astrophysical gravitational-wave signals from instrumental noise, which often contains transient non-Gaussian artifacts, astronomers have traditionally relied on bootstrap methods such as time slides. Bootstrap methods sample with replacement, comparing single-observatory data to construct a background distribution, which is used to assign a false-alarm probability to candidate signals. While bootstrap methods have played an important role establishing the first gravitational-wave detections, there are limitations. First, as the number of detections increases, it makes increasingly less sense to treat single-observatory data as bootstrap-estimated noise, when we know that the data are filled with astrophysical signals, some resolved, some unresolved. Second, it has been known for a decade that background estimation from time-slides eventually breaks down due to saturation effects, yielding incorrect estimates of significance. Third, the false alarm probability cannot be used to weight candidate significance, for example when performing population inference on a set of candidates. Given recent debate about marginally resolved gravitational-wave detection claims, the question of significance has practical consequences. We propose a Bayesian framework for calculating the odds that a signal is of astrophysical origin versus instrumental noise without bootstrap noise estimation. We show how the astrophysical odds can safely accommodate glitches. We argue that it is statistically optimal. We demonstrate the method with simulated noise and provide examples to build intuition about this new approach to significance.

New Critical Matrix Models and Generalized Universality

description: We study a class of one-matrix models with an action containing nonpolynomial terms. By tuning the coupling constants in the action to criticality we obtain that the eigenvalue density vanishes as an arbitrary real power at the origin, thus defining a new class of multicritical matrix models. The corresponding microscopic scaling law is given and possible applications to the chiral phase transition in QCD are discussed. For generic coupling constants off-criticality we prove that all microscopic correlation functions at the origin of the spectrum remain in the known Bessel universality class. An arbitrary number of Dirac mass terms can be included and the corresponding massive universality is maintained as well. We also investigate the critical behavior at the edge of the spectrum: there, in contrast to the behavior at the origin, we find the same critical exponents as derived from matrix models with a polynomial action.

description: Using first-principles calculations we determine the role of compressive and tensile uniaxial and equibiaxial strain on the structural, electronic and magnetic properties of V$_2$O$_3$. We find that compressive strain increases the energy cost to transition from the high-temperature paramagnetic metallic phase to the low-temperature antiferromagnetic insulating phase. This shift in the energy difference can be explained by changes in the V-V bond lengths that are antiferromagnetically aligned in the low temperature structure. The insights that we have obtained provide a microscopic explanation for the shifts in the metal-insulator transition temperature that have been observed in experiments of V$_2$O$_3$ films grown on different substrates.

description: We report on the results from a Chandra ACIS observation of the young, compact, supernova remnant N103B. The unprecedented spatial resolution of Chandra reveals sub-arcsecond structure, both in the brightness and in spectral variations. Underlying these small-scale variations is a surprisingly simple radial structure in the equivalent widths of the strong Si and S emission lines. We investigate these radial variations through spatially resolved spectroscopy using a plane-parallel, non-equilibrium ionization model with multiple components. The majority of the emission arises from components with a temperature of 1 keV: a fully ionized hydrogen component; a high ionization timescale (n_e*t > 10^12 s cm^-3) component containing Si, S, Ar, Ca, and Fe; and a low ionization timescale (n_e*t ~ 10^{11} s cm^-3) O, Ne, and Mg component. To reproduce the strong Fe Kalpha line, it is necessary to include additional Fe in a hot (> 2 keV), low ionization (n_e*t ~ 10^10.8 s cm^-3) component. This hot Fe may be in the form of hot Fe bubbles, formed in the radioactive decay of clumps of 56Ni. We find no radial variation in the ionization timescales or temperatures of the various components. Rather, the Si and S equivalent widths increase at large radii because these lines, as well as those of Ar and Ca, are formed in a shell occupying the outer half of the remnant. A shell of hot Fe is located interior to this, but there is a large region of overlap between these two shells. In the inner 30% of the remnant, there is a core of cooler, 1 keV Fe. We find that the distribution of the ejecta and the yields of the intermediate mass species are consistent with model prediction for Type Ia events.

description: This paper analyses the efficiency of EU internal dairy markets between 2000 and 2014 from spatial price integration perspective, employing a cross-methodological approach in three steps. First, we analyse the spatial integration of raw milk markets, which is often used to test the efficiency of agricultural markets. National monthly raw milk price data are tested for integration and whether the Law of One Price (LOP) holds. Second, we assess integration results in a binary choice setting, employing gravity model variables. Finally, in order to partly overcome the often cited drawback of price transmission analysis (i.e. that by employing price variables (only), there is no connection with real trade flows), bidirectional network analysis models are designed using export variables. Country specific network centrality measures were contrasted with the frequency of LOP fulfilment. Results suggest that besides the milk volume traded, the position occupied in the trade network structure should be also considered when market integration is analysed.

description: We have investigated electronic structures of a newly discovered antiperovskite superconductor MgCNi$_3$ and related compounds MgBNi$_3$ and MgNNi$_3$. In MgCNi$_3$, a peak of very narrow and high density of states is located just below $\rm E_F$, which corresponds to the $π^*$ antibonding state of Ni-3d and C-$2p$ but with the predominant Ni-3d character. The prominent nesting feature is observed in the $Γ$-centered electron Fermi surface of an octahedron-cage-like shape that originates from the 19th band. The estimated superconducting parameters based on the simple rigid-ion approximation are in reasonable agreement with experiment, suggesting that the superconductivity in MgCNi$_3$ is described well by the conventional phonon mechanism.

description: The paper identifies the degree of market imperfections in the input processing market and provides a comparative analysis among the different EU countries and different industries. For detection of the abuse of oligopsonistic/monopsonistic behavior a mark down model using stochastic frontier methodology was derived. The results show that the input food processing market is characterized by some degree of non-competitive behavior in all analysed sectors - slaughtering, fruits and vegetables, dairy and milling. However, the degree of market imperfections differs among the sectors as well as within individual sectors. In particular, the EU slaughtering common market is characterised by considerably greater market imperfections as compared to the dairy and milling sectors. Moreover, significant differences among EU member countries in individual countries were revealed by the estimate in all analysed sectors. In particularly, some companies are characterized by significant oligopsony market power.
Deconfinement transition in three-dimensional compact U(1) gauge theories coupled to matter fields

description: It is shown that permanent confinement in three-dimensional compact U(1) gauge theory can be destroyed by matter fields in a deconfinement transition. This is a consequence of a non-trivial infrared fixed point caused by matter, and an anomalous scaling dimension of the gauge field. This leads to a logarithmic interaction between the defects of the gauge-fields, which form a gas of magnetic monopoles. In the presence of logarithmic interactions, the original electric charges are unconfined. The confined phase which is permanent in the absence of matter fields is reached at a critical electric charge, where the interaction between magnetic charges is screened by a pair unbinding transition in a Kosterlitz-Thouless type of phase-transition.

description: We consider covert communication, i.e., hiding the presence of communication from an adversary for multiple-input multiple-output (MIMO) additive white Gaussian noise (AWGN) channels. We characterize the maximum covert coding rate under a variety of settings, including different regimes where either the number of transmit antennas or the blocklength is scaled up. We show that a non-zero covert capacity can be achieved in the massive MIMO regime in which the number of transmit antennas scales up but under specific conditions. Under such conditions, we show that the covert capacity of MIMO AWGN channels converges the capacity of MIMO AWGN channels. Furthermore, we derive the order-optimal scaling of the number of covert bits in the regime where the covert capacity is zero. We provide an insightful comparative analysis of different cases in which secrecy and energy-undetectability constraints are imposed separately or jointly.

description: The EU is a major player in the global wheat market. This paper examines the pricing behavior of EU wheat exporters using a pricing-to-market (PTM) analysis. Wheat is an exemplary product for testing PTM theories as it is widely and frequently traded, and it is largely unbranded. We estimate the relationship between export unit values and exchange rates using quarterly panel data for 11 export destinations for 2000- 2013. Results show that there is a meaningful long-run relationship between export unit values and exchange rates, but there is little evidence of differential mark-ups between export markets.

description: The dynamics of an elastic medium driven through a random medium by a small applied force is investigated in the low-temperature limit where quantum fluctuations dominate. The motion proceeds via tunneling of segments of the manifold through barriers whose size grows with decreasing driving force $f$. In the limit of small drive, at zero-temperature the average velocity has the form $v\propto\exp[-{\rm const.}/\hbar^α f^μ]$. For strongly dissipative dynamics, there is a wide range of forces where the dissipation dominates and the velocity--force characteristics takes the form $v\propto\exp[-S(f)/\hbar]$, with $S(f)\propto 1/ f^{(d+2ζ)/(2-ζ)}$ the action for a typical tunneling event, the force dependence being determined by the roughness exponent $ζ$ of the $d$-dimensional manifold. This result agrees with the one obtained via simple scaling considerations. Surprisingly, for asymptotically low forces or for the case when the massive dynamics is dominant, the resulting quantum creep law is {\it not} of the usual form with a rate proportional to $\exp[-S(f)/\hbar]$; rather we find $v\propto \exp\{-[S(f)/\hbar]^2\}$ corresponding to $α=2$ and $μ= 2(d+2ζ-1)/(2-ζ)$, with $μ/2$ the naive scaling exponent for massive dynamics. Our analysis is based on the quasi-classical Langevin approximation with a noise obeying the quantum fluctuation--dissipation theorem. The many space and time scales involved in the dynamics are treated via a functional renormalization group analysis related to that used previously to treat the classical dynamics of such systems. Various potential difficulties with these approaches to the multi-scale dynamics -- both classical and quantum -- are raised and questions about the validity of the results are discussed.

description: Since 2000, Russia has substantially increased grain production and exports. The grain output growth has come from a rise in yields rather than area. After falling heavily during the 1990’s, grain area stabilized during the 2000’s and has remained flat, at about two-thirds the level of the late Soviet period. Using data on the regional structure of Russian grain production costs, this paper examines the country’s potential to increase grain output further by returning the lost grain area to production. The analysis finds that if grain area were to grow beyond a certain level, that is still well below the level of the late Soviet period, production costs would rise steeply. Therefore, any major expansion in grain area would require that world grain prices rise considerably beyond their level in the early 2010’s, to cover the high marginal costs of production.

description: We study how the solution of the two-dimensional Dirichlet boundary problem for smooth simply connected domains depends upon variations of the data of the problem. We show that the Hadamard formula for the variation of the Dirichlet Green function under deformations of the domain reveals an integrable structure. The independent variables corresponding to the infinite set of commuting flows are identified with harmonic moments of the domain. The solution to the Dirichlet boundary problem is expressed through the tau-function of the dispersionless Toda hierarchy. We also discuss a degenerate case of the Dirichlet problem on the plane with a gap. In this case the tau-function is identical to the partition function of the planar large $N$ limit of the Hermitean one-matrix model.

description: Agricultural producers operate in a volatile environment, facing a number of sources of risk. A key question is whether farmers who are more highly skilled can better mitigate these risks and consistently earn higher returns than their lower skilled peers. In this article, farm management performance is analyzed based on yearly Illinois Farm Business Farm Management (FBFM) panel data across 6,760 farms from 1996 through 2011. Two out-of-sample measures of skill are used to analyze the ability of farm managers that consistently perform well over yearly and longer time horizons. Results suggest that the most skilled managers often generate better financial results. Furthermore, persistence tests show management skills are consistent and predictable.
Ab Initio Molecular Dynamics Study of Aqueous Solvation of Ethanol and Ethylene

description: The structure and dynamics of aqueous solvation of ethanol and ethylene are studied by DFT-based Car-Parrinello molecular dynamics. We did not find an enhancement of the structure of the hydrogen bonded network of hydrating water molecules. Both ethanol and ethylene can easily be accommodated in the hydrogen-bonded network of water molecules without altering its structure. This is supports the conclusion from recent neutron diffraction experiments that there is no hydrophobic hydration around small hydrophobic groups. Analysis of the electronic charge distribution using Wannier functions shows that the dipole moment of ethanol increases from 1.8 D to 3.1 D upon solvation, while the apolar ethylene molecule attains an average dipole moment of 0.5 D. For ethylene, we identified configurations with $π$-H bonded water molecules, that have rare four-fold hydrogen-bonded water coordination, yielding instantaneous dipole moments of ethylene of up to 1 D. The results provide valuable information for the improvement of empirical force fields, and point out that for an accurate description of the aqueous solvation of ethanol, and even of the apolar ethylene, polarizable force fields are required.

description: This paper examines the impacts of rural education on agricultural productivity in China. The approach we take involves two-stage process. First, we use DEA_Malmquist method to measure total factor productivity change, technical change and efficiency change in China over the period 1985 to 2011. We find that China has experienced an increase in total factor productivity, and that productivity growth was mostly attributed to technical progress, rather than to improvement in efficiency. And then, with a panel dataset covering 30 provinces, we investigate the impact of rural education on productivity growth of China. The results indicated that the development of rural education plays positive role on China’s agricultural productivity growth. Moreover, empirical results of regression models show that rural education enhances agricultural total factor productivity through technological progress rather than by promoting technical efficiency.

description: Abstract: Here we demonstrate a magnetic resonance coupling based wireless triboelectric nanogenerator (TENG) and fully self-powered wireless sensors. By integrating a microswitch and an inductor with the TENG, the pulsed voltage output is converted into a sinusoidal voltage signal with a fixed frequency. This can be transmitted wirelessly from the transmit coil to the resonant-coupled receiver coil with an efficiency of 73% for a 5 cm distance between the two coils (10 cm diameter). Analytic models of the oscillating and coupled voltage signals for the wireless energy transfer are developed, showing excellent agreement with the experimental results. A TENG of 40 × 50 mm2 can wirelessly light up 70 LEDs or charge up a 15 μF capacitor to 12.5 V in ~90 s. The system is further utilized for two types of fully self-powered wireless chipless sensors with no microelectronic components. The technologies demonstrate an innovative strategy for a wireless ‘green’ power source and sensing.

description: This paper examines the impact of Ontario’s Greenbelt legislation, a land use policy that permanently protects over 1.8 million acres of land from non-agricultural development, on farmers’ exit and investment decisions. A farm-level panel data set for 32,512 farms in Ontario is used to perform two econometric estimations: a correlated random effects Probit model of farm exit and a dynamic unobserved effects Tobit model of farm investment. The Greenbelt policy is found to have influenced both farm exit and farm investment decisions, with the impact varying depending on location within the Greenbelt. In particular, the results indicate evidence of a negative impact on farm investment, which is contrary to one of the objectives of the Greenbelt policy.

description: This thesis develops new econometric methodologies for estimating the causal impacts of policy interventions using real-world observational data when interventions may not be randomly allocated to individuals. Rather than only estimating the average policy effects, the methods focus on estimating the whole distribution of the heterogeneous policy effects across individuals using longitudinal data, including those who gain and those who lose, providing more nuanced information for policy evaluation. The models were used to evaluate the impacts of exercises on individuals’ body weights.
