Assessment of Reproductive Performance, Growth and Survival of Hybrids of African Catfish ( Clarias gariepinus ) and Indian Catfish ( Clarias batrachus ) Compared to Their Parental Lines Crosses

Hybridization was conducted to compare performance of hybrids to their parental line of the pure Clarias gariepinus and Clarias batrachus crosses as a control in triplicates for a period of 60 days, with fortnightly sampling. The hybrid crosses showed intermediate characters between the control crosses in mean weight gain (MWG), specific growth rate (SGR) mean final length (MFL) and survival of fingerlings (SF). However, the hybrids revealed lower characters compared to the progeny of control groups in fertilization rate, hatching and survival of larvae. On the other hand, fertilization and hatching rate among the hybrids and the control batrachus species were statistically insignificant (P>0.05). Similarly, no significant difference (P>0.05) was observed between the two inter-specific hybrids. Though the crosses of C. gariepinus displayed significantly higher value in MWG, SGR, SL and FML than other groups, fingerling survival was found to be lowest. The growth parameters like MWG, SGR and FML of the hybrids were found to be higher than C. batrachus crosses, while survival of hybrid fingerlings were higher than C. gariepinus. Therefore, this is considered as heterosis vigor for the hybrids for that they have achieved better traits either one of the control groups.
Pea seed extracts stimulate germination of the terrestrial orchid Ophrys apifera Huds. during a habitat restoration project

Novel methods are required to break the seed dormancy of temperate-zone orchids and aid the conservation of rare species. Zeatin is produced in increasing concentrations during the development of pea (Pisum sativum) seeds. We hypothesised that hot water extracts of pea seeds stimulate germination of the orchid Ophrys apifera in vitro, particularly for extractions made during later pea development. Pea seeds, exposed to 0, 3, 6, 9, 12 or 15 days of periodic wetting, were extracted in hot water and the extracts were added to Malmgren's growth medium. Germination of O. apifera on this medium was quantified after 7 months, stimulated by a range of pure hormones. Pea seed extract collected later in pea development (at 6–15 days) inhibited germination of O. apifera. However, extracts taken at 0 and 3 days significantly increased germination from 3.8 ± 0.32% in the control to 9.1 ± 1.84% and 7.6 ± 0.79%, respectively: increases comparable to the most effective of the pure hormones. Dried peas therefore provide an economical alternative source of germination stimulants for orchids. We briefly report how sufficient mature plants of O. apifera were produced to allow a population to be multiplied to 15 times its original size during a habitat restoration project.
Covariates of Women Reproductive Span in Manipur: A Life Table Approach

The life time between marriage as initial event and menopause or sterilization as terminal event is defined as Reproductive Life Span of a woman. A retrospective cross-sectional study has been conducted to check the covariates risk of the life span. Using censored data, Cox’s Model (1972) explores the set of covariates of reproductive span of the 973 eligible women aged 35-55 years under cluster sampling technique. The sample survey was conducted in the rural areas of Manipur valley during the period from May to December, 2013 taking the 1st May, 2013 as reference date of the survey. Using SPSS, the risk of exposure in the life span is reduced due to the effects of educational level (P<0.01) and use of contraceptives (P<0.01). The life span has been reduced by sterilization about half of the duration (15 yrs) from the menopause (29 yrs). Identification and management of the high risk factors by program implementing agencies at a level consistent with replacement fertility is urgently needed in the population.
Economic consequences of intifada

Abstract In 2003 the World Bank (WB) and the International Monetary Fund (IMF) published estimates of macro-economic indicators for 2002 of the economy of Palestine. The WB used a micro-founded recursive dynamic computable general equilibrium (CGE) model, calibrated on the 1998 Social Accounting Matrix (SAM) of Palestine, to which shocks were applied, whereas the IMF based its estimates on a macro-founded income-expenditure model relying on more recent data. It turned out that there were substantial differences: the estimate by the WB of the real gross national income (at 1998 prices) was 25% less than the corresponding figure calculated by the IMF. This huge difference is not only relevant for a full understanding of the economic consequences of the intifada, but also for the size of the international community intervention. In this paper we propose our own evaluation with the help of a static CGE model, based on the 1998 SAM and the so-called intifada shock derived from data of the WB that we constructed for the analysis of some forms of emergency assistance in a previous article. It turns out that our estimates, based on an entirely different methodology, are remarkably close to those of the IMF.
DefArabicQA: Arabic Definition Question Answering System

Today the Web is the largest resource of knowledge and, therefore, sometimes this makes it difficult to find precise information. Current search engines can only return ranked snippets containing the effective answers to a query user. But, they can not return the exact answers. Question Answering systems present the solution to obtain effective and exact answers to a user question asked in natural language question instead of keywords query. Unfortunately, Question Answering task for the Arabic language has not been investigated enough in the last decade, compared to other languages. In this paper, we tackle the definition Question Answering task for the Arabic language. We propose an Arabic definitional Question Answering system based on a pattern approach to identify exact and accurate definitions about organization using Web resources. We experimented this system using 2000 snippets returned by Google search engine and Wikipedia Arabic version and a set of 50 organization definition questions. The obtained results are very encouraging: (90%) of the questions used have complete (vital) definitions in the top-five answers and (64%) of them have complete definitions in the top-one answer. MRR was (0.81).
Toward efficiency in heterogeneous multispecies reactive transport modeling: A particle‐tracking solution for first‐order network reactions

Modeling multispecies reactive transport in natural systems with strong heterogeneities and complex biochemical reactions is a major challenge for assessing groundwater polluted sites with organic and inorganic contaminants. A large variety of these contaminants react according to serial‐parallel reaction networks commonly simplified by a combination of first‐order kinetic reactions. In this context, a random‐walk particle tracking method is presented. This method is capable of efficiently simulating the motion of particles affected by first‐order network reactions in three‐dimensional systems, which are represented by spatially variable physical and biochemical coefficients described at high resolution. The approach is based on the development of transition probabilities that describe the likelihood that particles belonging to a given species and location at a given time will be transformed into and moved to another species and location afterward. These probabilities are derived from the solution matrix of the spatial moments governing equations. The method is fully coupled with reactions, free of numerical dispersion and overcomes the inherent numerical problems stemming from the incorporation of heterogeneities to reactive transport codes. In doing this, we demonstrate that the motion of particles follows a standard random walk with time‐dependent effective retardation and dispersion parameters that depend on the initial and final chemical state of the particle. The behavior of effective parameters develops as a result of differential retardation effects among species. Moreover, explicit analytic solutions of the transition probability matrix and related particle motions are provided for serial reactions. An example of the effect of heterogeneity on the dechlorination of organic solvents in a three‐dimensional random porous media shows that the power‐law behavior typically observed in conservative tracers breakthrough curves can be largely compromised by the effect of biochemical reactions.
Reclaiming Dark Silicon Using Thermally-Aware Chiplet Organization in 2 . 5 D Integrated Systems

As on-chip power densities of manycore systems continue to increase, one cannot simultaneously run all the cores due to thermal constraints. This phenomenon, known as the ‘dark silicon’ problem, leads to inactive regions on the chip and limits the performance of manycore systems. This paper proposes to reclaim dark silicon through a thermally-aware chiplet organization technique in 2.5D manycore systems. The proposed technique adjusts the interposer size and the spacing between adjacent chiplets to reduce the peak temperature of the overall system. In this way, a system can operate with a larger number of active cores at a higher frequency without violating thermal constraints, thereby achieving higher performance. To determine the chiplet organization that jointly maximizes performance and minimizes manufacturing cost, we formulate and solve an optimization problem that considers temperature and interposer size constraints of 2.5D systems. We design a multi-start greedy approach to find (near-)optimal solutions efficiently.

High school philosophy teachers’ use of textbooks: Critical thinking or teaching to the text?

Ontario is the only North American, English-speaking jurisdiction to include philosophy in secondary schools. In this first study to examine Ontario high school philosophy courses, we investigated what sorts of textbooks teachers used, how they used them, and the reasons for their pedagogical choices when using textbooks. Despite claims that philosophy promotes critical thinking, an online survey of 53 high school philosophy teachers and personal interviews with a subset of 14 revealed their use of textbooks did not match this ideal. Teachers cited insecurities with knowledge, a lack of pedagogical training, their own perception that students were incapable of challenging texts, and pressure to meet provincial curriculum policy demands as factors that contributed to their pedagogical choices.
Alkaline-Earth Atoms in Optical Tweezers

We demonstrate single-shot imaging and narrow-line cooling of individual alkaline earth atoms in optical tweezers; specifically, strontium-88 atoms trapped in $515.2~\text{nm}$ light. We achieve high-fidelity single-atom-resolved imaging by detecting photons from the broad singlet transition while cooling on the narrow intercombination line, and extend this technique to highly uniform two-dimensional arrays of $121$ tweezers. Cooling during imaging is based on a previously unobserved narrow-line Sisyphus mechanism, which we predict to be applicable in a wide variety of experimental situations. Further, we demonstrate optically resolved sideband cooling of a single atom close to the motional ground state of a tweezer. Precise determination of losses during imaging indicate that the branching ratio from $^1$P$_1$ to $^1$D$_2$ is more than a factor of two larger than commonly quoted, a discrepancy also predicted by our ab initio calculations. We also measure the differential polarizability of the intercombination line in a $515.2~\text{nm}$ tweezer and achieve a magic-trapping configuration by tuning the tweezer polarization from linear to elliptical. We present calculations, in agreement with our results, which predict a magic crossing for linear polarization at $520(2)~\text{nm}$ and a crossing independent of polarization at 500.65(50)nm. Our results pave the way for a wide range of novel experimental avenues based on individually controlled alkaline earth atoms in tweezers -- from fundamental experiments in atomic physics to quantum computing, simulation, and metrology implementations.
Some properties of nonlinear wave systems

Nonlinear wave phenomena remain poorly understood, and significant results are limited to either very special examples or situations for which perturbation methods are adequate. The former case is typified by exactly solvable equations and the important role played by solitons. For the latter class of problems, the evolution of weak interactions, resonances, and slowly varying wave trains are well-known examples. Despite the limitations of each approach, these studies have stimulated a large volume of mathematical research and considerable interest in the applied disciplines. One objective of the present paper is to report on some results for nonlinear wave systems that do not fall into either of the above categories. The appro'ach taken is to study a particular case in some detail and, on the basis of the results obtained, to speculate on some anticipated general characteristics of nonlinear
Probing and characterizing the growth of a crystal of ultracold bosons and light

The non-linear coupled particle light dynamics of an ultracold gas in the field of two independent counter-propagating laser beams can lead to the dynamical formation of a self-ordered lattice structure as presented in (2016) Phys. Rev. X 6 021026. Here we present new numerical studies on experimentally observable signatures to monitor the growth and properties of such a crystal in real time. While, at least theoretically, optimal non-destructive observation of the growth dynamics and the hallmarks of the crystalline phase can be performed by analyzing scattered light, monitoring the evolution of the particle’s momentum distribution via time-of-flight probing is an experimentally more accessible choice. In this work we show that both approaches allow us to unambiguously distinguish the crystal from independent collective scattering as it occurs in matter wave super-radiance. As a clear crystallization signature, we identify spatial locking between the two emerging standing laser waves, together creating the crystal potential. For sufficiently large systems, the system allows reversible adiabatic ramping into the crystalline phase as an alternative to a quench across the phase transition and growth from fluctuations.
Optimizing the AC resistance of multilayer transformer windings with arbitrary current waveforms

AC losses due to nonsinusoidal current waveforms have been found by calculating the losses at harmonic frequencies when the Fourier coefficients are known. An optimized foil or layer thickness in a winding may be found by applying the Fourier analysis over a range of thickness values. This paper presents a new formula for the optimum foil or layer thickness, without the need for Fourier coefficients and calculations at harmonic frequencies. The new formula requires the RMS value of the current waveform and the RMS value of its derivative. It is simple, straightforward and applies to any periodic waveshape.
Supporting Sophisticated Modeling Practices in Secondary Science

Schwarz and colleagues proposed a learning progression for modeling that provides a valuable template for envisioning increasingly sophisticated levels of modeling practice (Fortus, Shwartz, & Rosenfeld, 2016; Schwarz et al., 2009; Schwarz, Reiser, Archer, Kenyon, & Fortus, 2012). Thinking about learning progressions for modeling, however, involves challenges in coordinating between aggregate curricular arcs and supporting individuals’ learning. First, students’ purposes for modeling and the nature of the context shape individual student performances. Second, approaches for longitudinally supporting students in modeling is a relatively nascent endeavor. Third, research on the highest levels of the progression is often hypothetical, because few students demonstrate high-level practices in classrooms. In response to these challenges, we partnered with an eighth grade teacher in a semester-long design-based study. In this paper, we explore conceptual and representational contexts designed to support sophisticated modeling practices and beliefs and analyze the nature of high-level performances achieved through these contexts.

Non Invasive 3 D Tracking for Augmented Video Applications

In this work we present a tracking method that has demonstrated to be accurate enough for creating augmented videos from the information obtained by a standard pinhole camera. It is based on the well known epipolar geometry concept. The proposed implementation can make all the tracking and calibration process automatically and has the advantage of not to need any marker in the scene, imposing only a few restrictions in the motion of the camera.

Autonomy and Emotion Management. Middle managers in welfare professions during radical organizational change

This case study was conducted among middle managers during a period of radical change within the Norwegian child welfare service. Our goal was to explore how the middle managers handle and respond to emotional dissonance and constraints in autonomy during the change process. We collected data through group meetings, individual interviews, and focus groups. Prior research on middle managers has shown their importance in the implementation of organizational change. We propose that middle managers conduct emotion work, emotional labor, and emotional balancing in response to the increased complexity of organizational expectations during change processes. Further, we argue that the need for relevant emotion management reflects a threat to managers’ autonomy. Our findings indicate that middle managers feel emotional dissonance, due to their position as both recipients and executers of organizational change. This makes them vulnerable to questions of loyalty, and they feel they have no backstage where they can express themselves openly. However, their ability to plan emotion management and to balance various conflicting expectations enables them to maintain autonomy during a radical change process. Our basic arguments and findings are summarized by applying the logic of a historistic functional model.
Feedback control design for subsonic cavity flows

A benchmark problem in active aerodynamic ∞ow control, suppression of strong pressure oscillations induced by ∞ow over a shallow cavity, is addressed in this paper. Proper orthogonal decomposition and Galerkin projection techniques are used to obtain a reduced- order model of the ∞ow dynamics from experimental data. The model is made amenable to control design by means of a control separation technique, which makes the control input ap- pear explicitly in the equations. A prediction model based on quadratic stochastic estimation correlates ∞ow fleld data with surface pressure measurements, so that the latter can be used to reconstruct the state of the model in real time. The focus of this paper is on the controller design and implementation. A linear-quadratic optimal controller is designed on the basis of the reduced-order model to suppress the cavity ∞ow resonance. To account for the limitation on the magnitude of the control signal imposed by the actuator, the control action is modifled by a scaling factor, which plays the role of a bifurcation parameter for the closed-loop system. Experimental results, in qualitative agreement with the theoretical analysis, show that the con- troller achieves a signiflcant attenuation of the resonant tone with a redistribution of the energy into other frequencies, and exhibits a certain degree of robustness when operating in ofi-design conditions.
Transdimensional inverse thermal history modeling for quantitative thermochronology

[1] A new approach for inverse thermal history modeling is presented. The method uses Bayesian transdimensional Markov Chain Monte Carlo and allows us to specify a wide range of possible thermal history models to be considered as general prior information on time, temperature (and temperature offset for multiple samples in a vertical profile). We can also incorporate more focused geological constraints in terms of more specific priors. The Bayesian approach naturally prefers simpler thermal history models (which provide an adequate fit to the observations), and so reduces the problems associated with over interpretation of inferred thermal histories. The output of the method is a collection or ensemble of thermal histories, which quantifies the range of accepted models in terms a (posterior) probability distribution. Individual models, such as the best data fitting (maximum likelihood) model or the expected model (effectively the weighted mean from the posterior distribution) can be examined. Different data types (e.g., fission track, U-Th/He, 40Ar/39Ar) can be combined, requiring just a data-specific predictive forward model and data fit (likelihood) function. To demonstrate the main features and implementation of the approach, examples are presented using both synthetic and real data.
