description: The decrease in the production capacity of some poultries and sudden death of the birds in these poultries are as a result of not having ideal power that will make some of these poultries to function efficiently. This was overcome by introducing improved electric power availability in the poultry farmat Amoli community in Enugu State for an increased output using intelligent standalone hybrid renewable energy system. This was done by characterizing the availability of electric power in poultry farm, establishing the causes of power unavailability in poultry farm in AMOLI community in Enugu State that triggered the low production capacity, determining available sources of renewable energy that will boost electric power availability in poultry farm at AMOLI community and subsequently improved its production capacity. The study designed a   standalone rule-base that improves the availability of the electric power in poultry farm thereby enhancing its production capacity. A Simulink model used for improving the availability of electric power in poultry farm was designed. The percentage improvement of the availability of electric power and its production capacity in poultry farm at AMOLI community in Enugu State were validated and justified. The result obtained with the conventional electric power availability in poultry farm was 70KW that caused low production in the poultry. This was because conventional electric power could not meet the threshold of 72 through 75KW. On the other hand, when standalone was integrated in the system it becomes73.78KW thereby improving the production capacity of the poultry and the number of chickens hatched in poultry farm at the community was 1000 with the conventional while when standalone was integrated in the system hatched chickens were 1054. With these results the percentage improvement in the production capacity of the poultry was5.4%.

description: We present a detailed analysis of the magnetic field structure found in general relativistic 3D MHD simulations of accreting tori in the Kerr metric with different black hole spins. Among the properties analyzed are the field strength as a function of position and black hole spin, the shapes of field lines, the degree to which they connect different regions, and their degree of tangling. We investigate prior speculations about the structure of the magnetic fields and discuss how frequently certain configurations are seen in the simulations. We also analyze the distribution of current density, with a view toward identifying possible locations for magnetic energy dissipation.

description: Lipoxygenases (LOX) are enzymes that catalyze polyunsaturated fatty acid peroxidation and have a non-heme iron atom located in their active site. They are implicated in the arachidonic acid pathway and involved in inflammation, fever, pain production, and in the origins of several diseases such as cancer, asthma, and psoriasis. The search for inhibitors of these enzymes has emerged in the last years, and isoflavonoids have a broad spectrum of biological activity with low cytotoxicity. Our previous results have shown that isoflavonoids inhibited different LOX isoforms in vitro. For this reason, we studied the most important interactions that govern the potency and selectivity of some isoflavones and isoflavans toward different LOX isoforms using computational methods. The docking results have shown that all the molecules can be located in different zones in the LOX active site. Steered molecular dynamics indicated that selectivity was present at the cavity entry, but not at its exit. We also observed the correlation between the potential mean force and the best (HIR-303) and worst inhibitors (IR-213) in 5-LOX. Finally, structure–activity relationship (QSAR) studies showed a good correlation between theoretical IC50 values and experimental data for 5-LOX and 12-LOX with 96 and 95%, respectively, and a lower correlation for 15-LOX (79%). Conclusively, pharmacophore analysis showed that our proposed molecules should possess a donor–acceptor and aromatic centers to encourage interactions in the active site.
Proposal of a spin-one chain model with competing dimer and trimer interactions

description: A new kind of spin-1 chain Hamiltonian consisting of competing dimer and trimer projection operators is proposed. As the relative strengths and signs of the interactions are varied, the model exhibits a number of different phases including the gapped dimer phase and the gapless trimer phase with critical correlations described by a conformal field theory with central charge $c=2$. A symmetry-protected topological phase also exists in this model, even though the microscopic interactions are not the simple adiabatic extensions of the well-known Heisenberg and the Affleck-Kennedy-Lieb-Tasaki model and contains both two- and three-particle permutations. A fourth phase is characterized by macroscopically degenerate ground states. While bearing almost a one-to-one resemblance to the phase diagram of the bilinear-biquadratic spin-1 chain Hamiltonian, our model is rooted on very different physical origin, namely the two competing tendencies of spin-1 particles to form singlets through either dimer or trimer formation.

description: An exactly solvable bounce model in loop quantum cosmology is identified which serves as a perturbative basis for realistic bounce scenarios. Its bouncing solutions are derived analytically, demonstrating why recent numerical simulations robustly led to smooth bounces under the assumption of semiclassicality. Several effects, easily included in a perturbative analysis, can however change this smoothness. The effective theory is not only applicable to such situations where numerical techniques become highly involved but also allows one to discuss conceptual issues. For instance, consequences of the notoriously difficult physical inner product can be implemented at the effective level. This indicates that even physical predictions from full quantum gravity can be obtained from perturbative effective equations.

description: Strictly zero-dimensional biframes were introduced by Banaschewski and Brümmer as a class of strongly zero-dimensional biframes including the congruence biframes. We consider the category of strictly zero-dimensional biframes and show it is both complete and cocomplete. We characterise the extremal monomorphisms in this category and explore the special position that congruence biframes hold in it. Finally, we provide an internal characterisation of congruence biframes, and hence, of congruence frames.

description: King George Island (KGI), which is located between the Antarctic and South American continents, may play a crucial role in the exchange of Bryozoa amongst the various Antarctic sectors and across the Polar Front. Knowledge regarding the biological diversity of this area could help us understand the evolution of the Antarctic ecosystem and its connectivity to the South American continent as well as the colonization ability of particular species. Here, we investigate the patterns of diversity and biogeographic affiliation of the cheilostome Bryozoa from KGI and the surrounding areas. Of 114 identified taxa from a depth range of 6–492 m, 26 species were reported for the first time in KGI. The most speciose genera were Camptoplites, Osthimosia, Smittina, and Cellarinella. Species richness at KGI consisted of 70% of the total bryozoans at the South Shetland Islands (SSI). Fifty-nine per cent of the bryozoans from KGI are endemic to Antarctica, which closely reflects the previously estimated endemism rate for bryozoans and other Antarctic taxa. Cluster analysis indicated that the strongest faunal links of SSI bryozoans were with Antarctic Peninsula assemblages, corresponding to the physical distance between both locations. The biogeographic similarities between SSI and South America confirm the broad trend of existing Antarctic–South American faunal links previously observed in bryozoans and many other taxa and indicate that SSI might be an important transitional zone between Antarctica and South America.

description: The process of heralded noiseless amplification, and the inverse process of heralded noiseless attenuation, have potential applications in the context of quantum communications. Although several different physical implementations of heralded noiseless amplifiers have now been demonstrated, the research on heralded noiseless attenuators has been largely confined to a beam-splitter based approach. Here we show that an optical parametric amplifier (OPA), combined with appropriate heralding, can also serve as a heralded noiseless attenuator. The counterintuitive use of an optical amplifier as an attenuator is only possible due to the probabilistic nature of the device.

description: For a system of N spins 1/2 there are quantum states that can encode a direction in an intrinsic way. Information on this direction can later be decoded by means of a quantum measurement. We present here the optimal encoding and decoding procedure using the fidelity as a figure of merit. We compute the maximal fidelity and prove that it is directly related to the largest zeroes of the Legendre and Jacobi polynomials. We show that this maximal fidelity approaches unity quadratically in 1/N. We also discuss this result in terms of the dimension of the encoding Hilbert space.

description: We present H$α$-derived star-formation rates (SFRs) for the galaxy cluster CL J0023+0423B at $z = 0.845$. Our $3σ$ flux limits corresponds to a star-formation rate of 0.24 \smy, and our minimum reliable H$α$ + [N II] equivalent width is $> 10$ Å, demonstrating that near-infrared narrow-band imaging can sample the star-forming galaxy population in distant clusters. Comparison with spectroscopy shows that the number of false detections is low ($9 \pm 6$%) and that our H$α$ equivalent widths are correlated with spectroscopically determined [O II] equivalent widths. A magnitude-limited spectroscopic survey conducted over the same area missed 70% of the star-forming galaxies and 65% of the integrated star formation. Using Hubble Space Telescope Wide Field Planetary Camera 2 Archive images, we fit Sersic profiles to all galaxies with significant narrow-band equivalent widths and find that equivalent width decreases as the steepness of galaxy profile increases. We find no significant population of early type galaxies with ongoing star formation. The integrated SFR per cluster mass of CL J0023+0423B is a factor of ten higher than that of the three $z \sim 0.2$ clusters in the literature with available H$α$ observations. A larger sample of $z \sim 0.8$ clusters spanning a range of cluster masses is needed to determine whether this variation is due to a difference in cluster mass or redshift.

description: The land-use pattern for many cities is a central business district surrounded by sprawling suburbs. This pattern can lead to an inefficient and congestion-prone transportation system due to a reliance on automobiles. This is because high-capacity transit is inefficient in low-density areas where insufficient travelers can access transit. This also poses an equity concern as the monetary cost of faster and more expensive travel disproportionately burdens low income travelers, especially when fixed congestion pricing is imposed. This paper presents a deterministic approximation of a discrete choice model for mixed access and mainline transportation modes, meaning that travelers may use different modes to access a mainline system, such as transit. The purpose is to provide a tractable computationally efficient model to address the first/last mile problem using a system-wide pricing policy that can account for heterogeneous values of time; a problem that is difficult to solve efficiently using a stochastic model. The model is structured for a catchment area around a central access point for a mainline mode, approximating choice by comparing modal utility costs. The underlying utility model accommodates both fixed prices (e.g., parking, fixed tolls, and fares) and distance-based unit prices (e.g. taxi fare, bike-share, and distance tolls) that may be set in a coordinated way with respect to value of time. Using numerical analysis to assess accuracy, the deterministic model achieved results within 3% of a stochastic logit-based model, and within 7% of measured values. The optimization of prices using the final model achieved a 22% reduction in generalized travel time and a 30% improvement in the Gini inequity measure from 0.2 to 0.14.

description: We investigate whether a generic multipartite pure state can be the unique asymptotic steady state of locality-constrained purely dissipative Markovian dynamics. In the simplest tripartite setting, we show that the problem is equivalent to characterizing the solution space of a set of linear equations and establish that the set of pure states obeying the above property has either measure zero or measure one, solely depending on the subsystems' dimension. A complete analytical characterization is given when the central subsystem is a qubit. In the N-partite case, we provide conditions on the subsystems' size and the nature of the locality constraint, under which random pure states cannot be quasi-locally stabilized generically. Beside allowing for the possibility to approximately stabilize entangled pure states that cannot be exact steady states in settings where stabilizability is generic, our results offer insights into the extent to which random pure states may arise as unique ground states of frustration free parent Hamiltonians. We further argue that, to high probability, pure quantum states sampled from a t-design enjoy the same stabilizability properties of Haar-random ones as long as suitable dimension constraints are obeyed and t is sufficiently large. Lastly, we demonstrate a connection between the tasks of quasi-local state stabilization and unique state reconstruction from local tomographic information, and provide a constructive procedure for determining a generic N-partite pure state based only on knowledge of the support of any two of the reduced density matrices of about half the parties, improving over existing results.

description: Article purpose: This study has aims to determine if men have a higher adherence to physiotherapy exercises for low back pain (LBP) than women or vice versa; and the factors prohibiting a patient’s adherence to exercises and how these differ between men and women. Material and methods: Two methods that included patients’ exercise journal and questionnaire survey were used. First, a clinical observational study in designated physiotherapy practices whereby three patients’ exercise journals and physiotherapists were collected for case reviews. Second, a cross-sectional survey of community using closed-ended questionnaire. The statistical tool Microsoft Excel Analysis Tool PAK and an analysis of variance (ANOVA) Student’s paired t-test was used for data analysis. Results: Men and women showed higher levels of adherence to different perspectives of adherence. The main limiting factors for all individuals to prescribed exercises were health and time. Males and females showed some differences in other limiting factors, but there is no significant difference between genders. Conclusions: Overall, it will be inductive fallacy of generalisation to claim that a specific gender is less adherent to physiotherapy exercises for LBP. The observation of insignificant gender differences in some limiting factors provides additional piece of information to physiotherapists that when aiming to achieve or improve adherence to physiotherapy exercises, each patient should be treated on a case-by-case basis.

description: We report further results from a 191 ks Chandra observation of the core of the Perseus cluster, Abell 426. The emission-weighted temperature and abundance structure is mapped detail. There are temperature variations down to ~1 kpc in the brightest regions. Globally, the strongest X-ray surface brightness features appear to be caused by temperature changes. Density and temperature changes conspire to give approximate azimuthal balance in pressure showing that the gas is in hydrostatic equilibrium. Si, S, Ar, Ca, Fe and Ni abundance profiles rise inward from about 100 kpc, peaking at about 30-40 kpc. Most of these abundances drop inwards of the peak, but Ne shows a central peak, all of which may be explained by resonance scattering. There is no evidence for a widespread additional cooler temperature component in the cluster with a temperature greater than a factor of two from the local temperature. There is however evidence for a widespread hard component which may be nonthermal. The temperature and abundance of gas in the cluster is observed to be correlated in a manner similar to that found between clusters.

description: We study the properties of cosmological density perturbations in a multi-component system consisting of a scalar field and a perfect fluid. We discuss the number of degrees of freedom completely describing the system, introduce a full set of dynamical gauge-invariant equations in terms of the curvature and entropy perturbations, and display an efficient formulation of these equations as a first-order system linked by a fairly sparse matrix. Our formalism includes spatial gradients, extending previous formulations restricted to the large-scale limit, and fully accounts for the evolution of an isocurvature mode intrinsic to the scalar field. We then address the issue of the adiabatic condition, in particular demonstrating its preservation on large scales. Finally, we apply our formalism to the quintessence scenario and clearly underline the importance of initial conditions when considering late-time perturbations. In particular, we show that entropy perturbations can still be present when the quintessence field energy density becomes non-negligible.

description: We compare two strategies of multi-detector detection of compact binary inspiral signals, namely, the coincidence and the coherent. For simplicity we consider here two identical detectors having the same power spectral density of noise, that of initial LIGO, located in the same place and having the same orientation. We consider the cases of independent noise as well as that of correlated noise. The coincident strategy involves separately making two candidate event lists, one for each detector, and from these choosing those pairs of events from the two lists which lie within a suitable parameter window, which then are called as coincidence detections. The coherent strategy on the other hand involves combining the data phase coherently, so as to obtain a single network statistic which is then compared with a single threshold. Here we attempt to shed light on the question as to which strategy is better. We compare the performances of the two methods by plotting the Receiver Operating Characteristics (ROC) for the two strategies. Several of the results are obtained analytically in order to gain insight. Further we perform numerical simulations in order to determine certain parameters in the analytic formulae and thus obtain the final complete results. We consider here several cases from the relatively simple to the astrophysically more relevant in order to establish our results. The bottom line is that the coherent strategy although more computationally expensive in general than the coincidence strategy, is superior to the coincidence strategy - considerably less false dismissal probability for the same false alarm probability in the viable false alarm regime.

description: To conveniently prepare the immobilized enzyme for green synthesis of vitamin A palmitate, thermomyces lanuginosus lipase (TLL) was assembled with apatite derived from calcium phosphate in solution to form TLL@apatite hybrid nanoflowers (hNFs) by mimetic biomineralization. The obtained hNFs was characterized by SEM and applied in the enzymatic synthesis of vitamin A palmitate. Under optimal condition, when palmitic acid and vitamin A acetate were used as substrates, the yield of the target product was up to 90.4%, about 1.5 folds of that using free TLL. In addition, when each cycle for catalytic synthesis was carried out in petroleum ether with 20% water content as solvent for 12 h, the hNFs still retains 65.8% of initial catalytic synthetic ability after 10 cycles. These results demonstrated the hNFs was a kind of green biocatalyst with high catalytic activity and high stability with great potential in the green pharmaceuticals industry.

description: A linear quantum dynamical theory for squeezing the output of the trapped Bose-Einstein condensate is presented with the Bogoliubov approximation. We observe that the non-classical properties, such as sub-Poisson distribution and quadrature squeezing effect, mutually oscillate between the quantum states of the applied optical field and the resulting atom laser beam with time. In particular, it is shown that an initially squeezed optical field will lead to squeezing in the outcoupled atomic beam at later times.

Water-enhanced interdiffusion of major elements between natural shoshonite and high-K rhyolite melts

description: The interdiffusion of six major elements (Si, Ti, Fe, Mg, Ca, K) between natural shoshonite and a high-K calc-alkaline rhyolite (Vulcano island, Aeolian archipelago, Italy) has been experimentally measured by the diffusion couple technique at 1200°C, pressures from 50 to 500 MPa and water contents from 0.3 (nominally dry) to 2 wt%. The experiments were carried out in an internally heated pressure vessel, and major element profiles were later acquired by electron probe microanalysis. The concentration-distance profiles are evaluated using a concentration-dependent diffusivity approach. Effective binary diffusion coefficients for four intermediate silica contents are obtained by the Sauer-Freise modified Boltzmann-Matano method. At the experimental temperature and pressures, the diffusivity of all studied elements notably increases with dissolved H2O content. Particularly, diffusion is up to 1.4 orders of magnitude faster in a melt containing 2 wt.% H2O than in nominally dry melts. This effect is slightly enhanced in the more mafic compositions. Uphill diffusion was observed for Al, while all other elements can be described by the concept of effective binary interdiffusion. Ti is the slowest diffusing element through all experimental conditions and compositions, followed by Si. Fe, Mg, Ca and K diffuse at similar rates but always more rapidly than Si and Ti. This trend suggests a strong coupling between melt components. Since effects of composition (including water content) are dominant, a pressure effect on diffusion cannot be clearly resolved in the experimental pressure range.

Cosmological density fluctuations and gravity waves: A covariant approach to gauge-invariant non-linear perturbation theory

Subjects: subject: Astrophysics (astro-ph)

description: We present a new approach to gauge-invariant cosmological perturbations at second order, which is also covariant. We examine two cases in particular for a dust Friedman-Lemaitre-Robertson-Walker model of any curvature: we investigate gravity waves generated from clustering matter, that is, induced tensor modes from scalar modes; and we discuss the generation of density fluctuations induced by gravity waves -- scalar modes from tensor perturbations. We derive a linear system of evolution equations for second-order gauge-invariant variables which characterise fully the induced modes of interest, with a source formed from variables quadratic in first-order quantities; these we transform into fully-fledged second-order gauge-invariant variables. Both the invariantly defined variables and the key evolution equations are considerably simpler than similar gauge-invariant results derived by other methods. By finding analytical solutions, we demonstrate that non-linear effects can significantly amplify or dampen modes present in standard linearised cosmological perturbation theory, thereby providing an important source of potential error in, and refinement of, the standard model. Moreover, these effects can dominate at late times, and on super-Hubble scales.

description: Aestheticization is nothing new under the sun. Potentially, all texts – even instructional ones – may function in an aesthetic way, because aesthetics relate to the expressive dimension of messages and all verbal messages consist of this dimension. The purpose of this article is to use insights from literary studies, more specifically from structuralism, to understand how people curate their own way of life in late modern society. The core question is: Which strategies do people use when aestheticizing their life? And the answer is: Approximately the same strategies as those utilized in aesthetic or aestheticized texts. Such strategies are identified in an analysis of two sentences. The analysis explores the aesthetic principles at work in these sentences and the strategies these principles serve: i.e. embellishment and estrangement. In the concluding discussion, these two strategies are discussed in relation to everyday aesthetics, and a third strategy is identified: aesthetic evolution.

description: Twin-peak quasi-periodic oscillations (QPOs) are observed in several low-mass X-ray binary systems containing neutron stars (NSs). Timing analysis of X-ray fluxes of more than dozen of such systems reveals remarkable correlations between the frequencies of two characteristic peaks present in the power density spectra. The individual correlations clearly differ, but they roughly follow a common individual pattern. High values of measured QPO frequencies and strong modulation of the X-ray flux both suggest that the observed correlations are connected to orbital motion in the innermost part of an accretion disc. Several attempts to model these correlations with simple geodesic orbital models or phenomenological relations have failed in the past. We find and explore a surprisingly simple analytic relation that reproduces individual correlations for a group of several sources through a single parameter. When an additional free parameter is considered within our relation, it well reproduces the data of a large group of 14 sources. The very existence and form of this simple relation supports the hypothesis of the orbital origin of QPOs and provides the key for further development of QPO models. We discuss a possible physical interpretation of our relation's parameters and their links to concrete QPO models.
