description: The study objectives were to assess the technical and economic performance of sheep and goats enterprises in new land territories in Egypt. The study used a sample survey of a sample size 15 farm in Noubaria region, Behira Governorate; the sample covered the data of the 2011 agricultural year. In addition to the descriptive statistics estimates, the financial statements were analyzed to estimate the profitability and return to investment. Estimated technical performance indicators of sheep and goats production in new land of Egypt showed that the average lambing rate of the herd was about 80%, and the rate of twining was about 10%, and the followed breeding policy was 3 lambing every 2 years, and the mortality rate from birth to weaning was around 26%, and growing the lambs was from weight 22kg initial weight to 47kg selling weight for 90 days with a daily growth rate about 0.2774 live weight. The feeding system was 1.274 of concentrate feed mix. The average operating costs per ewe (with its followers) was about? Where the variable costs represented 52% and mostly feed costs. The rest was imputed fixed costs which included full time family labor and management. The cost of fattening the lambs was 76% of the total herd's cost. The average annual income per ewe with its followers was? The most important item of income was the cash sales (61%). All profitability indicators were positive and feasible, which means that all the sheep and goats farms in new territories achieved positive net profit, and covered all items of costs, either paid or imputed. Therefore, sheep enterprising in new land showed a promising opportunity for generating feasible employment for landless farmers that could be moved from the Nile valley. The profit margin was 20% and the return to investment rate was 15%. However such rate has shown high sensitivity to the increase in concentrate feed price. Even though, sheep breeding and lambs fattening in small to medium flocks in new land territories provide two other positive externalities which are improving the poor soil fertility in such areas and baring un favorite climate conditions in such arid and semi- and regions

description: Phishing websites is a problem on internet that target the people amenabilities rather than software vulnerabilities. It can be described as it is the process of collecting sensitive information such as usernames and passwords. Types of web pages are different in terms of their features. Phishing occurs when a malicious site acts as a legitimate for obtaining sensitive information such as passwords, account information, or credit card numbers. Phishing attacks can be prevented by detecting websites and notifying users to detect phishing websites. Machine learning algorithms have been one of the most effective techniques for detecting phishing websites. Nowadays, information and communication tools are used in a manner that is very dense with information. For this purpose, various solution methods are developed for various problem. Machine Learning (ML) methods be used in application development for in security purpose. Prediction and decision support system and great benefits can be provided to the person who is responsible for information security. Today, it has become an increasingly popular subject in developing intelligent application. Hence, we use a web page features set to avoid phishing attacks. We proposed a model based on machine learning techniques to detect phishing web pages. We have suggested some rules to have efficient features. The model has 13 inputs and 1 output. The average classification accuracy was measured as 75%.

Temporal and spatial variation in habitat quality : breeding ecology of the chestnut-backed chickadee in uncut and partial cut forests in British Columbia
Creators: name: Mahon, Carmen Lisa
Publisher: name: University of British Columbia
Year: 2010

description: I examined how partial cutting influenced the use and selection of habitat by chestnut-backed chickadees (Poecile rufescens). My objectives were: (1) to examine the variability of nest survival and identify the contributions of year, harvest treatment and habitat characteristics, and predator activity at 3 spatial scales, (2) to compare use and selection of nesting habitat in uncut, partial cut-mature, and partial cut-old sites at 3 spatial scales, and (3) to identify the influence of habitat structure or annual differences in food abundance and predation pressure on reproductive output. I found that nest predation rates fluctuated between years: 56% in 2000, 64% in 2001, 10% in 2002, and 12% in 2003. Survival models revealed that only the covariate year reliably predicted nest survival time at the stand and nest patch scales, while year and nest height predicted survival time at the nest tree scale. I found no effect of harvest treatment in the stand, nest patch, and nest tree models. Squirrel population density, space use, and activity near nest areas did not differ between years. Indirect effects on nest survival may have occurred due to temporal changes in habitat quality for squirrels. Chestnut-backed chickadees exhibited flexibility in resource selection when selecting nest sites. I found no correlation between the density of breeding chickadees and structural characteristics at the stand scale, but found selection of similar resources at the nest patch and nest tree scales. When selecting nest trees, chickadees in my system used a variety of tree species, conditions, sizes, nest site locations, and cavity types. Reproductive output showed no consistent pattern across sites, and was highly variable among years. Chickadee foraging patterns differed between years suggesting annual changes in prey abundance and type, although reproductive output did not decrease with a decline in primary prey. Predators had the greatest impact on the daily mortality rate of nesting chickadees. Indices of predator density did not differ among years; a functional response by predators due to changes in their food supply may have strongly influenced annual reproductive output of chickadees in this population.

description: Two-dimensional boron structures, due to the diversity of properties, attract great attention because of their potential applications in nanoelectronic devices. A series of \ce{TiB_x} ($4\leq x \leq 11$) monolayers are efficiently constructed through our motif based method and theoretically investigated through high-throughput first-principles calculations. The configurations are generated based on motifs of boron triangular/quadrilateral fragments and multicoordinate titanium-centered boron molecular wheels. Besides priviously reported \ce{TiB4} which was discovered by global search method, we predict that high symmetry monolayers \ce{TiB7} (Cmmm) and \ce{TiB9} (P31m) which are octa-coordinate and nona-coordinate titanium boride are thermodynamic stable. The \ce{TiB7} monolayer is a BCS superconductor with the transition temperature $T_c$ up to 8K. The motif based approach is proved to be efficient in searching stable structures with a prior knowledge so that the potentially stable transition metal monolayers can be quickly constructed by using basic cluster motifs. As an efficient way of discovering materials, the method is easily extended to predict other type of materials which have common characteristic pattern in the structure.
A co-evolutionary cellular automata for the integration of spatial and temporal scales in forest management planning
Creators: name: Mathey, Anne-Hélène
Publisher: name: University of British Columbia
Year: 2010

description: The scope of forest management has broadened to encompass ever more values and services. Designing decision support tools to provide for them involves incorporating a number of spatial and dynamic processes. This thesis presents a case for more holistic numerical planning tools which can handle spatial objectives and inter-temporal trade-offs. A novel algorithm based on cellular automata (CA) is designed to address forest planning objectives that are both spatial and temporal and subject to global constraints. In this decentralized framework, the landscape management goals are achieved through a co-evolutionary decision process between interdependent stands. The problem considered is maximization of cumulative harvest volume and amount of clustered old forest subject to stable flow and minimum old growth retention. Applied to a small test area, the model demonstrates short computation time and shows sensitivity to both local constraints and global goals and constraints. The implementation requirements of forest planning models are an issue that affects both the efficacy and the efficiency of planning tools. It is argued that object-oriented implementations could efficiently integrate the spatial and temporal data required by the various processes underpinning forest planning tools. An object-oriented design for the previously developed CA-based algorithm proves capable of considering spatial relationships with consistent allocation of clustered old growth areas. The object orientation permits a fast computation of both local and global limitations on local decision making and speedy modification of the problem definition (local and global requirements or spatial resolution). Finally, the CA-based planning approach is used on a large scale planning problem to investigate different policy scenarios. The problem under investigation is the impact on volume flow and net present value of introducing intensive forest management (IFM) and clustering harvest activities. The main trade-off in this study was found to be between volume and net present value. In this context, IFM is used to meet the harvest targets from a smaller land base but at increased costs. Spatially clustering harvest activities, however, greatly increases the output net present value of a plan.

description: Software requirement selection is to find an optimal set of requirements that gives the highest value for a release of software while keeping the cost within the budget. However, value-related dependencies among software requirements may impact the value of an optimal set. Moreover, value-related dependencies can be of varying strengths. Hence, it is important to consider both the existence and the strengths of value-related dependencies during a requirement selection. The existing selection models however, either assume that software requirements are independent or they ignore strengths of requirement dependencies. This paper presents a cost-value optimization model that considers the impacts of value-related requirement dependencies on the value of selected requirements (optimal set). We have exploited algebraic structure of fuzzy graphs for modeling value-related requirement dependencies and their strengths. Validity and practicality of the work are verified through carrying out several simulations and studying a real world software project.
Evolution of Intermediate-Mass Black Hole X-Ray Binaries

description: The majority of the ultraluminous X-ray sources (ULXs) in external galaxies are believed to be accreting black holes in binary systems; some of the black holes could be as massive as $\sim 100-1000 \ms$. We have performed evolution calculations for intermediate-mass black hole X-ray binaries, assuming they are formed in dense star clusters via tidal capture. The results are compared with those for stellar-mass black holes X-ray binaries. We find that these two types of black holes may have similar companion stars and binary orbits if observed as ULXs. However, intermediate-mass black holes seem to be favored in explaining the most luminous ULXs. We also discuss the possibilities of transient behavior and beamed emission in the evolution of these binary systems.

description: Rare-earth doped nanocrystals are emerging light sources used for many applications in nanotechnology enabled by human ability to control their various optical properties with chemistry and material science. However, one important optical problem -- polarisation of photoluminescence -- remains largely out of control by chemistry methods. Control over photoluminescence polarisation can be gained via coupling of emitters to resonant nanostructures such as optical antennas and metasurfaces. However, the resulting polarization is typically sensitive to position disorder of emitters, which is difficult to mitigate. Recently, new classes of disorder-immune optical systems have been explored within the framework of topological photonics. Here we explore disorder-robust topological arrays of Mie-resonant nanoparticles for polarisation control of photoluminescence of nanocrystals. We demonstrate polarized emission from rare-earth-doped nanocrystals governed by photonic topological edge states supported by zigzag arrays of dielectric resonators. We verify the topological origin of polarised photoluminescence by comparing emission from nanoparticles coupled to topologically trivial and nontrivial arrays of nanoresonators.

description: We describe a quantum trajectories technique for the unraveling of the quantum adiabatic master equation in Lindblad form. By evolving a complex state vector of dimension $N$ instead of a complex density matrix of dimension $N^2$, simulations of larger system sizes become feasible. The cost of running many trajectories, which is required to recover the master equation evolution, can be minimized by running the trajectories in parallel, making this method suitable for high performance computing clusters. In general, the trajectories method can provide up to a factor $N$ advantage over directly solving the master equation. In special cases where only the expectation values of certain observables are desired, an advantage of up to a factor $N^2$ is possible. We test the method by demonstrating agreement with direct solution of the quantum adiabatic master equation for $8$-qubit quantum annealing examples. We also apply the quantum trajectories method to a $16$-qubit example originally introduced to demonstrate the role of tunneling in quantum annealing, which is significantly more time consuming to solve directly using the master equation. The quantum trajectories method provides insight into individual quantum jump trajectories and their statistics, thus shedding light on open system quantum adiabatic evolution beyond the master equation.

description: In the emerging field of quantum computation and quantum information, superconducting devices are promising candidates for the implementation of solid-state quantum bits or qubits. Single-qubit operations, direct coupling between two qubits, and the realization of a quantum gate have been reported. However, complex manipulation of entangled states - such as the coupling of a two-level system to a quantum harmonic oscillator, as demonstrated in ion/atom-trap experiments or cavity quantum electrodynamics - has yet to be achieved for superconducting devices. Here we demonstrate entanglement between a superconducting flux qubit (a two-level system) and a superconducting quantum interference device (SQUID). The latter provides the measurement system for detecting the quantum states; it is also an effective inductance that, in parallel with an external shunt capacitance, acts as a harmonic oscillator. We achieve generation and control of the entangled state by performing microwave spectroscopy and detecting the resultant Rabi oscillations of the coupled system.

description: We present the results of an intensive spectroscopic campaign in the optical waveband revealing that Cyg OB2 #8A is an O6 + O5.5 binary system with a period of about 21.9 d. Cyg OB2 #8A is a bright X-ray source, as well as a non-thermal radio emitter. We discuss the binarity of this star in the framework of a campaign devoted to the study of non-thermal emitters, from the radio waveband to gamma-rays. In this context, we attribute the non-thermal radio emission from this star to a population of relativistic electrons, accelerated by the shock of the wind-wind collision. These relativistic electrons could also be responsible for a putative gamma-ray emission through inverse Compton scattering of photospheric UV photons, thus contributing to the yet unidentified EGRET source 3EG J2033+4118.

description: Here we study the static and dynamic transport properties of a low energy two-band model proposed previously in E. Martino et al. [PRL 122, 217402 (2019), arXiv:1905.00280], with an anisotropic in-plane linear momentum dependence, and a parabolic out-of-plane dispersion. The model is extended to include a negative band gap, which leads to the emergence of a Weyl semimetal (WSM) state, as opposed to the gapped semimetal (GSM) state when the band gap is positive. We calculate and compare the zero and finite frequency transport properties of the GSM and WSM cases. The $dc$ properties that are calculated for the GSM and WSM cases are Drude spectral weight, mobility and resistivity. We determine their dependence on the Fermi energy and crystal direction. The in- and out-of-plane optical conductivities are calculated in the limit of the vanishing interband relaxation rate for both semimetals. The main common features are an $ω^{1/2}$ in-plane and $ω^{3/2}$ out-of-plane frequency dependence of the optical conductivity. We seek particular features related to the charge transport that could unambiguously point to one ground state over the other, based on the comparison with the experiment. Differences between the WSM and GSM are in principle possible only at extremely low carrier concentrations, and at low temperatures.

description: The properties of hadron screening masses around the deconfinement phase transition at finite baryonic density can be studied by evaluating the Taylor coefficients with respect to the iso-scalar and iso-vector chemical potentials. We simulate 2-flavour lattice QCD with staggered fermions on a 12*12*24*6 lattice with ma = 0.05 and 0.10 and report investigations of nucleon, pseudo-scalar and vector mesons. We present new, strong evidence that in the confining phase, the screening masses at vanishing chemical potential have significant temperature dependence, but the effect of the iso-scalar chemical potential is very small. Above the critical temperature, the second derivative terms of mesons rapidly increase as contrasted to the case of baryon. We also study the responses of the screening masses to an iso-vector chemical potential and discuss some of the issues related to the properties of hadron masses at finite density.

description: The $γp \to K^+ π^0 Λ$ and $γp \to K^+ πΣ$ reactions are studied in the kinematic region where the $π^0 Λ$(1116) and $πΣ$(1192) pairs originate dominantly from the decay of the $Σ$(1385) and $Λ$(1405) resonances. We consider laboratory photon energies around 2 GeV, significantly above the threshold for producing the $K^+ Σ$(1385) and $K^+ Λ$(1405) final states. We compute for both reactions the process in which the ingoing photon dissociates into a real K$^+$ and a virtual K$^-$, the off-shell K$^-$ scattering subsequently off the proton target to produce the $π^0 Λ$ or $πΣ$ pair. The $K^- p \to π^0 Λ$ and $K^- p \to πΣ$ amplitudes are calculated in the framework of a chiral coupled-channel effective field theory of meson-baryon scattering. The structure of the amplitudes reflects the dominance of the $Λ(1405)$ in the $πΣ$ channel and of the $Σ(1385)$ in the $πΛ$ channel. The full pion-hyperon final state interaction is included in these amplitudes. We extract from the calculated cross section the gauge-invariant double kaon pole term. We found this term to be large and leading to sizeable cross sections for both the $γp \to K^+ π^0 Λ$ and $γp \to K^+ πΣ$ reactions, in qualitative agreement with the scarce data presently available. Accurate measurements of these cross sections should make it possible to extract the contribution of the double kaon pole and hence to assess the possibility of studying kaon-nucleon dynamics ust below threshold through these reactions.

description: Light storage in an optical fiber is an attractive component in quantum optical delay line technologies. Although silica-core optical fibers are excellent in transmitting broadband optical signals, it is challenging to tailor their dispersive property to slow down a light pulse or store it in the silica-core for a long delay time. Coupling a dispersive and coherent medium with an optical fiber is promising in supporting long optical delay. Here, we load cold Rb atomic vapor into an optical trap inside a hollow-core photonic crystal fiber, and store the phase of the light in a long-lived spin-wave formed by atoms and retrieve it after a fully controllable delay time using electromagnetically-induced-transparency (EIT). We achieve over 50 ms of storage time and the result is equivalent to 8.7x10^-5 dB s^-1 of propagation loss in an optical fiber. Our demonstration could be used for buffering and regulating classical and quantum information flow between remote networks.

description: This study quantifies private and social levels of agricultural pesticide overuse by combining an abatement function approach to estimate the marginal benefits of pesticide use with the Pesticide Environmental Accounting (PEA) tool to estimate marginal social costs. We applied the method to one intensive vegetable production system in the mountainous north of Thailand by using farm and plot level survey data. We find that the exponential specification for the abatement effect of pesticides gives more realistic outcomes than the logistic specification. Based on an exponential specification, we estimate that private overuse is 78-79% of the applied quantify of pesticides, while social overuse is 79-80%. The difference between private and social overuse is small as the exponential form reaches an optimum at a relatively low level of pesticide use.
Tangent functor on microformal morphisms, and non-linear pullbacks for forms and cohomology
Creators: name: Voronov, Theodore Th.
Publisher: name: arXiv
Year: 2017
Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: We show how the tangent functor extends from ordinary smooth maps to "microformal morphisms" (also called "thick morphisms") of supermanifolds. Microformal morphisms generalize ordinary maps and correspond to formal canonical relations between the cotangent bundles specified by generating functions depending on position variables on the source manifold and momentum variables on the target manifold (as formal power expansions), regarded as part of the structure. Microformal morphisms act on functions by non-linear (in general) pullbacks. We obtain here non-linear pullbacks of (pseudo)differential forms and show that they respect the de Rham differentials as "non-linear chain maps" that can induce non-linear transformations of cohomology.

description: We study authomorphisms of $Ind$-groups of polynomial automorphisms (wich are singular) via tame approximations. Such objects were pioneeered in research by B.I.Plotkin
 We obtain a number of properties of $Aut(Aut(A))$, where $A$ is the polynomial or free associative algebra over the base field $K$. We prove that all $Ind$-scheme automorphisms of $Aut(K[x_1,\dots,x_n])$ are inner for $n\ge 3$, and all $Ind$-scheme automorphisms of $Aut(K\langle x_1,\dots, x_n\rangle)$ are semi-inner.
 As an application, we prove that $Aut(K[x_1,\dots,x_n])$ cannot be embedded into $Aut(K\langle x_1,\dots,x_n\rangle)$ by the natural abelianization. In other words, the {\it Automorphism Group Lifting Problem} has a negative solution. We explore close connection between the above results and the Jacobian conjecture type questions, formulate the Jacobian conjecture for fields of any characteristic.

Year: 2018
Subjects: subject: General Physics (physics.gen-ph)

description: The formalism is developed for a tree-dimensional ($3D$) nonlinear Stokes-Mueller polarimetry. The expressions are derived for the generalized $3D$ linear and nonlinear Stokes vectors, and the corresponding nonlinear Mueller matrix. The coherency-like Hermitian square matrix $X$ of susceptibilities is introduced, which is derived from the nonlinear Mueller matrix. The $X$-matrix is characterized by the index of depolarization. Several decompositions of the $X$-matrix are introduced. The $3D$ nonlinear Stokes-Mueller polarimetry formalism can be applied for three and higher wave mixing processes. The $3D$ polarimetric measurements can be used for structural investigations of materials, including heterogeneous biological structures. The $3D$ polarimetry is applicable for nonlinear microscopy with high numerical aperture objectives.

description: This paper approaches the migrant’s motivation to remit from a new, behavioural perspective. We apply the well-established Theory of Planned Behaviour (TPB) using a structural equation model for the first time for this specific research question. Our micro-dataset stems from a 2009/10 survey, covering Albanian migrants from Kosovo living in Germany as well as their home-country households. More than 90% of Kosovar migrants living in Germany remit. However, little is known about their underlying motivations. Our analytical results show that the migrant’s attitude and norms are decisive for the remitting behaviour. The common socio-economic approach lacks explanatory power backed by theory.

description: We compute the free energy of asymmetric nuclear matter in a Brueckner-Hartree-Fock approach at finite temperature, paying particular attention to the dependence on isospin asymmetry. The first- and second-order symmetry energies are determined as functions of density and temperature and useful parametrizations are provided. We find small deviations from the quadratic isospin dependence and very small corresponding effects on (proto)neutron star structure.

description: Since 2006 to nowadays sugar beet in Europe has suffered a deep transformation with the new Common Market Organization. That year, in Spain, farms gave up 50% of production quota. New century has come accompanied by different EU strategies, including the obligation of stimulating new energy sources development especially renewable energies. From a double perspective, the authors have made an empirical approach to learn about future viability of this sector in Spain. First of all, we present an economic analysis to reflect the actual situation of market goods offered by this farming. Then we present environmental efficiency analysis (Greenhouse Gases emissions) caused by sugar beet farms with the aim of studying environmental non-market goods derived from bio-ethanol production. Goods that take part of the environmental function of this economical activity as a positive externality which has become an essential characteristic of EU agrarian system.

description: A general error correction method is presented which is capable of correcting coherent errors originating from static residual inter-qubit couplings in a quantum computer. It is based on a randomization of static imperfections in a many-qubit system by the repeated application of Pauli operators which change the computational basis. This Pauli-Random-Error-Correction (PAREC)-method eliminates coherent errors produced by static imperfections and increases significantly the maximum time over which realistic quantum computations can be performed reliably. Furthermore, it does not require redundancy so that all physical qubits involved can be used for logical purposes.

description: We propose CheckDP, the first automated and integrated approach for proving or disproving claims that a mechanism is differentially private. CheckDP can find counterexamples for mechanisms with subtle bugs for which prior counterexample generators have failed. Furthermore, it was able to \emph{automatically} generate proofs for correct mechanisms for which no formal verification was reported before. CheckDP is built on static program analysis, allowing it to be more efficient and more precise in catching infrequent events than existing counterexample generators (which run mechanisms hundreds of thousands of times to estimate their output distribution). Moreover, its sound approach also allows automatic verification of correct mechanisms. When evaluated on standard benchmarks and newer privacy mechanisms, CheckDP generates proofs (for correct mechanisms) and counterexamples (for incorrect mechanisms) within 70 seconds without any false positives or false negatives.

description: For the complex quadratic family $q_c:z\mapsto z^2+c$, it is known that every point in the Julia set $J(q_c)$ moves holomorphically on $c$ except at the boundary points of the Mandelbrot set. In this note, we present short proofs of the following derivative estimates of the motions near the boundary points $1/4$ and $-2$: for each $z = z(c)$ in the Julia set, the derivative $dz(c)/dc$ is uniformly $O(1/\sqrt{1/4-c})$ when real $c\nearrow 1/4$; and is uniformly $O(1/\sqrt{-2-c})$ when real $c\nearrow -2$. These estimates of the derivative imply Hausdorff convergence of the Julia set $J(q_c)$ when $c$ approaches these boundary points. In particular, the Hausdorff distance between $J(q_c)$ with $0\le c<1/4$ and $J(q_{1/4})$ is exactly $\sqrt{1/4-c}$.
