description: A total of 300 freshwater fishes of two species (160 O. niloticus and 140 CL. gariepinus) of different sizes and life stages were randomly collected in different seasons alive or freshly dead from September 2018 to August 2019 from fish farms in Ismailia governorate, Egypt. Naturally infested fishes revealed few phatho gnomonic clinical signs as leathergy, erosion in fins, ulcers on skin in O. niloticus and Cl. gariepinus in severe cases. Postmortem examination showed presence of yellow cysts embeded in musculature and kidney of Cl. gariepinus and enlargement of liver with yellowish discoloration in O. niloticus. The total infestation rate was (74.33%); in O. niloticus (73.13%) and in Cl. gariepinus (75.71%). The isolated helminthes from O. niloticus were Eumesenia aegypticus (Digenetic trematodes) which isolated from intestine and Acanthocentis tilapiae was also found in its intestinal contents. Cl. gariepinus was infested with Orientocredium batrachoides (Digenetic trematodes), Monobothrioides species, Polyonchobthorium clarias (Cestodes) and Procamallanus laeviconchus, Paracamallanus cyathopharynx (Nematodes) which were isolated from intestine. While encysted metacercariae (EMC) were isolated from different organs of infested O. niloticus and Cl. gariepinus as gills, air sac, kidney, heart and musculature. Molecular diagnosis (PCR) was used to confirm infestation with helminthes parasites.

description: Cosmological Birefringence (CB) is a phenomenon, caused by parity violating modifications to electrodynamics, whereby the linear polarisation angle of light changes as photons traverse a vacuum. It is possible to use a number of different analysis techniques to constrain this effect using Cosmic Microwave Background (CMB) polarisation observations. We investigate two different methods of constraining direction dependent birefringence for present and future CMB experiments including BICEP/Keck, Simons Observatory (SO), and LiteBIRD . Specifically we compare the constraints placed on anisotropic CB from a quadratic estimator technique to those derived from estimates of the $B$-mode power-spectrum for the three different experiments. The constraints derived from estimates of the $B$-mode power spectrum are found to be comparable to those derived from quadratic estimator for BICEP/Keck and SO, but not LiteBIRD due to its larger sky coverage. These forecasted upper bounds for CB are converted to constraints on primordial magnetic fields and the coupling between photons and pseudo Nambu-Goldstone bosons. Finally we show that even with the best constraints on CB, for the respective experiments, the potentially induced $B$-mode power can act as a significant contaminant in the prospective measurement of primordial $B$-modes.

description: Chirality, handedness, is one of the most fundamental intriguing asymmetries in nature. By definition, chiral objects cannot be superimposed onto each other after mirror reflection operation. Numerous examples of chiral structures can be found in nature, for example, chiral molecules and chiral magnetic nanostructures. Moving electrons are associated with handedness by their own spins due to spin-orbit interaction thus exhibiting various emergent phenomena as they interact with chiral materials, which otherwise would not be observed in achiral systems. This new paradigm allows the potential development of new forms of devices or methods by utilizing reciprocal interaction of chiral objects with moving electron spins. This review updates the remarkable progresses in Spintronics on Chiral Objects that have been made over the past few years providing provides an outlook for new opportunities and potential applications with new insights.

description: We construct new geon-type black holes in D>3 dimensions for Einstein's theory coupled to gauge fields. A static nondegenerate vacuum black hole has a geon quotient provided the spatial section admits a suitable discrete isometry, and an antisymmetric tensor field of rank 2 or D-2 with a pure F^2 action can be included by an appropriate (and in most cases nontrivial) choice of the field strength bundle. We find rotating geons as quotients of the Myers-Perry(-AdS) solution when D is odd and not equal to 7. For other D we show that such rotating geons, if they exist at all, cannot be continuously deformed to zero angular momentum. With a negative cosmological constant, we construct geons with angular momenta on a torus at the infinity. As an example of a nonabelian gauge field, we show that the D=4 spherically symmetric SU(2) black hole admits a geon version with a trivial gauge bundle. Various generalisations, including both black-brane geons and Yang-Mills theories with Chern-Simons terms, are briefly discussed.

Dynamics of active nematic defects on the surface of a sphere

description: A nematic liquid crystal confined to the surface of a sphere exhibits topological defects of total charge $+2$ due to the topological constraint. In equilibrium, the nematic field forms four $+1/2$ defects, located at the corners of a regular tetrahedron inscribed within the sphere, since this minimizes the Frank elastic energy. If additionally the individual nematogens exhibit self-driven directional motion, the resulting active system creates large-scale flow that drives it out of equilibrium. In particular, the defects now follow complex dynamic trajectories which, depending on the strength of the active forcing, can be periodic (for weak forcing) or chaotic (for strong forcing). In this paper we derive an effective particle theory for this system, in which the topological defects are the degrees of freedom, whose exact equations of motion we subsequently determine. Numerical solutions of these equations confirm previously observed characteristics of their dynamics and clarify the role played by the time dependence of their global rotation. We also show that Onsager's variational principle offers an exceptionally transparent way to derive these dynamical equations, and we explain the defect mobility at the hydrodynamics level.

Values, meaning and identity : the case for morality
Creators: name: Boston, Alexander Holtby
Publisher: name: University of British Columbia
Year: 2009

description: Since Plato's time, there have been attempts to show that the generally altruistic way of life is superior to the totally selfish way of life. Drawing upon the conclusions of philosophers and social psychologists, I argue that it is better to have a fairly moral character than a totally selfish one. I first argue that it is possible to have genuinely altruistic motivations (rather than disguised selfish motivations). I then show that both the altruistic and the selfish way of life are genuine choices for rational beings. Next I argue that the nature of values is such that they require reinforcement from others in order for us to verify that what we believe to be values are indeed values. I further argue that values are unattainable for the totally selfish person. Subsequently, I point out that values are necessary for an agent to have a meaningful life, and very likely necessary for a human to be able to have a sense of self. Since most people desire to have a meaningful life and a sense of self, I argue that the benefits possible to the fairly moral person outweigh the benefits possible to the totally selfish one, even if the latter can disguise her selfishness completely.

Detecting Abrupt Changes in the Presence of Local Fluctuations and Autocorrelated Noise

description: Whilst there are a plethora of algorithms for detecting changes in mean in univariate time-series, almost all struggle in real applications where there is autocorrelated noise or where the mean fluctuates locally between the abrupt changes that one wishes to detect. In these cases, default implementations, which are often based on assumptions of a constant mean between changes and independent noise, can lead to substantial over-estimation of the number of changes. We propose a principled approach to detect such abrupt changes that models local fluctuations as a random walk process and autocorrelated noise via an AR(1) process. We then estimate the number and location of changepoints by minimising a penalised cost based on this model. We develop a novel and efficient dynamic programming algorithm, DeCAFS, that can solve this minimisation problem; despite the additional challenge of dependence across segments, due to the autocorrelated noise, which makes existing algorithms inapplicable. Theory and empirical results show that our approach has greater power at detecting abrupt changes than existing approaches. We apply our method to measuring gene expression levels in bacteria.

At each step, it removes a facility to minimize the resulting total distance from the customers to the remaining facilities. It stops when k facilities remain. We prove that, if the distance function is metric, then the approximation ratio of RGreedy is between ?(log n/ log log n) and O(log n).

description: The spontaneous creation of primordial black holes in a violently expanding Universe is a well studied phenomenon. Based on quantum gravity arguments, it has been conjectured that the early Universe might have undergone a lower dimensional phase before relaxing to the current $(3 + 1)$ dimensional state. In this article we combine the above phenomena: we calculate the pair creation rates of black holes nucleated in an expanding Universe, by assuming a dimensional evolution, we term ``oxidation'', from $(1 + 1)$ to $(2 + 1)$ and finally to $(3 + 1)$ dimensions. Our investigation is based on the no boundary proposal that allows for the construction of the required gravitational instantons. If, on the one hand, the existence of a dilaton non-minimally coupled to the metric is necessary for black holes to exist in the $(1 + 1)$ phase, it becomes, on the other hand, trivial in $(2 + 1)$ dimensions. Nevertheless, the dilaton might survive the oxidation and be incorporated in a modified theory of gravity in $(3 + 1)$ dimensions: by assuming that our Universe, in its current state, originates from a lower-dimensional oxidation, one might be led to consider the pair creation rate in a sub-class of the Horndeski action. Our findings for this case show that, for specific values of the Galileon coupling to the metric, the rate can be unsuppressed. This would imply the possibility of compelling parameter bounds for non-Einstein theories of gravity by using the spontaneous black hole creation.

description: The time evolution of optically excited carriers in semiconductor quantum wells and quantum dots is analyzed for their interaction with LO-phonons. Both the full two-time Green's function formalism and the one-time approximation provided by the generalized Kadanoff-Baym ansatz are considered, in order to compare their description of relaxation processes. It is shown that the two-time quantum kinetics leads to thermalization in all the examined cases, which is not the case for the one-time approach in the intermediate-coupling regime, even though it provides convergence to a steady state. The thermalization criterion used is the Kubo-Martin-Schwinger condition.

description: Different advanced bridge function closures are utilized to investigate the structural and thermodynamic properties of dense Yukawa one-component plasma liquids within the framework of integral equation theory. The isomorph-based empirically modified hypernetted-chain, the variational modified hypernetted-chain, the Rogers-Young and the Ballone-Pastore-Galli-Gazzillo approaches are compared at the level of thermodynamic properties, radial distribution functions and bridge functions. The comparison, based on accuracy and computational speed, concludes that the two modified hypernetted-chain approaches are superior and singles out the isomorph-based variant as the most promising alternative to computer simulations of structural properties of dense Yukawa liquids. The possibility of further improvement through artificial cross-over to exact asymptotic limits is studied.

In the presence of point disorder, the transition is universal with an exponent which depends only on the dimensionality of the extended defect. We also consider the unbinding transition of a single vortex line from a twin plane occupied by other vortices. We show that the critical properties of this transition depend strongly on the Luttinger liquid parameter which describes the long distance physics of the two-dimensional flux line array.

description: This study compares subsurface drip irrigation and sprinkler irrigation with respect to expected returns, aquifer life, nutrient utilization and accumulation in the production of irrigated corn using swine effluent and fresh groundwater from a depleting aquifer in the Oklahoma Panhandle. The results of the Dynamic Programming model indicate that SDI outperforms center pivot sprinkler irrigation in terms of NPV of net returns and reduced phosphorus accumulation in soil. Soil nitrogen accumulation in soil is greater with SDI. Groundwater depletion is projected to occur at the end of 36th year with center pivot irrigation.

description: In a preceding paper, using Eggleton's evolution code we have discussed the structure and evolution of low-mass W UMa type contact binaries without angular momentum loss (AML). The models exhibit cyclic behavior about a state of marginal contact on a thermal time-scale. Part of the time of each cycle is spent in contact and part in a semi-detached state. According to observations, W UMa systems suffer AML. We present the models of low-mass contact binaries with AML due to gravitational wave radiation (GR) or magnetic stellar wind (MSW) are presented. We find that gravitational radiation cannot prevent the cyclic evolution of W UMa systems, and the effect of gravitational radiation on the cyclic behavior of contact binary evolution is almost negligible. We also find that the most likely AML mechanism for W UMa systems is magnetic braking, and that magnetic braking effects can increase the period of the cyclic evolution, and shorten the fraction of the time spent in the poor thermal contact state. If W UMa stars do not undergo cyclic evolution, and their angular momentum loss is caused simultaneously by MSW of both components, we find that the value of the parameter, $λ$, should be taken a larger value in comparison with those derived from observations of single stars. This indicates that the AML efficiency in W UMa systems may be lowered in comparison with non-contact stars because of the less mass contained in the convective envelopes of the components in W UMa systems. If W UMa systems lose their angular momentum at a constant rate. An angular momentum rate of $\frac{{\rm dln}J}{{\rm d}t}\approx 1.6\times 10^{-9} {\rm yr^{-1}}$ can prevent the cyclic behaviour of the model, and the model can keep in good contact with an essentially constant depth of contact.

description: We perform an exploratory study of the operator product expansion of the quark propagator on the lattice at short distance in coordinate space. This permits a simple determination of the quark condensate, ^MS(2 GeV)=(-265\pm 5\pm 22 MeV)^3, and of the renormalization constant of the quark field, Z^MS(2 GeV)=0.871 \pm 0.003 \pm 0.020. This new method also provides a remarkable non-perturbative test of the OPE predictions at short distance in QCD.

description: The viscous and thermal relaxation rates of an interacting fermion gas are calculated as functions of temperature and scattering length, using a many-body scattering matrix which incorporates medium effects due to Fermi blocking of intermediate states. These effects are demonstrated to be large close to the transition temperature $T_c$ to the superfluid state. For a homogeneous gas in the unitarity limit, the relaxation rates are increased by nearly an order of magnitude compared to their value obtained in the absence of medium effects due to the Cooper instability at $T_c$. For trapped gases the corresponding ratio is found to be about three due to the averaging over the inhomogeneous density distribution. The effect of superfluidity below $T_c$ is considered to leading order in the ratio between the energy gap and the transition temperature.

description: The gravitational strong equivalence principle (SEP) is a cornerstone of the general theory of relativity (GR). The extreme difference in binding energy between neutron stars and white dwarfs allows for precision tests of the SEP via the technique of pulsar timing. To date, the best limit on the validity of SEP under strong-field conditions was obtained with a unique pulsar in a triple stellar system, PSR J0337+1715. We report here on an improvement of this test using an independent data set acquired over 6 years with the Nan\c cay radio telescope (NRT). The improvements arise from a uniformly sampled data set, a theoretical analysis, and a treatment that fixes some short-comings in the previously published results, leading to better precision and reliability of the test. In contrast to the previously published test, we use a different long-term timing data set, developed a new timing model and an independent numerical integration of the motion of the system, and determined the masses and orbital parameters with a different methodology that treats the parameter $Δ$, describing a possible strong-field SEP violation, identically to all other parameters. We obtain a violation parameter $Δ= (+0.5 \pm 1.8) \times 10^{-6}$ at 95\% confidence level, which is compatible with and improves upon the previous study by 30\%. This result is statistics-limited and avoids limitation by systematics as previously encountered. We find evidence for red noise in the pulsar spin frequency, which is responsible for up to 10\% of the reported uncertainty. We use the improved limit on SEP violation to place constraints on a class of well-studied scalar-tensor theories, in particular we find $ω_{\rm BD} > 140\,000$ for the Brans-Dicke parameter. The conservative limits presented here fully take into account current uncertainties in the equation for state of neutron-star matter.

description: The strong subadditivity of entropy plays a key role in several areas of physics and mathematics. It states that the entropy S[ρ]= - Tr (ρ\ln ρ) of a density matrix ρ_{123} on the product of three Hilbert spaces satisfies S[ρ_{123}] - S[ρ_{23}] \leq S[ρ_{12}]- S[ρ_2]. We strengthen this to S[ρ_{123}] - S[ρ_{12}] \leq \sum_αn^α(S[ρ_{23}^α] - S[ρ_2^α]), where the n^αare weights and the ρ_{23}^αare partitions of ρ_{23}. Correspondingly, there is a strengthening of the theorem that the map A -> Tr \exp[L + \ln A] is concave. As applications we prove some monotonicity and convexity properties of the Wehrl entropy and entropy inequalities for quantum gases.

description: This paper investigates the relationships between country of origin labeling (COOL) issues and consumers concern about safety and health towards using of foreign produce. Results show that those who were married, self employed, had higher incomes, or possessed more education were more likely to support COOL. A consumer survey showed that about 84% of respondents overall, and more specifically, about 84% of female and 83% of male respondents would like markets to provide information about country of origin of fresh produce. The result also shows that about 73% of respondents regularly read food advertisements in newspapers and grocery brochures.
Gender assignment and word-final pronunciation in French: Two Classification Systems
Creators: name: Beckett, Margaret
Publisher: name: Monash University

Subjects: subject: 200306 French Language
subject: FOS: Languages and literature

description: Previous phonological, morphological and semantic analyses of gender in French cannot fully account for gender assignment and changes in word-final pronunciation for French nouns or for loan words entering the French lexicon. The writer's own experiences, and the extensive research of Tucker et al. (1977) into the ability of native French speakers to predict gender assignment accurately, suggested the potential for underlying rule-based phenomena. Until now, the intuitive recognition of the significance of word-final phonology that suggested some formal link with gender assignment has provided only limited predictability. This thesis argues that French gender assignment and work-final pronunciation can be explain more adequately with reference to semantic principles similar to those of the morpho-syntactically complex classifier systems found in languages of Africa, Asia, Australia and South America. Like some of those languages, French involves not one but two separate, independent nominal classification systems. The primary classification system relates to gender though agreement and is semantically determined in terms of a limited range of oppositional features linked to masculine or feminine. An equally important secondary nominal classification system, also semantically determined, reflects a different set of oppositional features encoded on the noun through word-final surface phonetic constraints. Features pertaining to gender concern binary oppositions in form, mode of existence, and quantity. Many of the features in the French system occur as organising principles in other languages (eg. animate:inanimate, etc.). For living entities, attributes concern nature and the various ways that organic matter is perceived.
