description: With the localization of fast radio bursts (FRBs) to galaxies similar to the Milky Way and the detection of a bright radio burst from SGR J1935+2154 with energy comparable to extragalactic radio bursts, a magnetar origin for FRBs is evident. By studying the environments of FRBs, evidence for magnetar formation mechanisms not observed in the Milky Way may become apparent. In this paper, we use a sample of FRB host galaxies and a complete sample of core-collapse supernova (CCSN) hosts to determine whether FRB progenitors are consistent with a population of magnetars born in CCSNe. We also compare the FRB hosts to the hosts of hydrogen-poor superluminous supernovae (SLSNe-I) and long gamma-ray bursts (LGRBs) to determine whether the population of FRB hosts is compatible with a population of transients that may be connected to millisecond magnetars. After using a novel approach to scale the stellar masses and star-formation rates of each host galaxy to be statistically representative of $z=0$ galaxies, we find that the CCSN hosts and FRBs are consistent with arising from the same distribution. Furthermore, the FRB host distribution is inconsistent with the distribution of SLSNe-I and LGRB hosts. With the current sample of FRB host galaxies, our analysis shows that FRBs are consistent with a population of magnetars born through the collapse of giant, highly magnetic stars.

description: This report details the findings of a research evaluation conducted for Sydney Metro (Transport for NSW) exploring the effectiveness of the Fast Tracking the Future Education professional development program and resource development. The program was conducted in 2018 through the Education Knowledge Network at Western Sydney University, in partnership with Sydney Metro. The program required participating primary and secondary teachers to apply their professional learning through the design, implementation and teacher-evaluation of inquiry-based units of work, using the Sydney Metro infrastructure project as a stimulus. The completed units of work were aligned with the NSW curriculum and were implemented in the participants’ schools across a range of grade levels from Kindergarten to Year 10. The professional development program influenced the implementation of inquiry-based learning by providing the participating teachers with in-depth knowledge if inquiry-based teaching approaches alongside detailed information about the Sydney Metro infrastructure project.

description: Με τη βοήθεια της στήλης πολυαμιδίου και της στήλης Sephadex LH-20 σε παρασκευαστικό επιίδεδο απομονώθηκαν πέντε ουσίες οι οποίες φάνηκε ότι ήταν εστέρες της απιγενίνης με καφεϊκό και κουμαρικό οξύ, καθώς και αιθέρες των οξέων αυτών με την απιγενίνη. Οσον αφορά στην αντιοξειδωτική ικανότητα του εκχυλίσματος του αιθέρα, εκτιμήθηκε με δύο τρόπους και έδειξε να είναι σημαντική. Ειδικά στη μέθοδο της χημειοφωταύγειας το αιθερικό εκχύλισμα έδειξε να έχει μεγαλύτερη δράση αντιοξειδωτική δύναμη από όλα τα πρότυπα διαλύματα. Η αντιοξειδωτική ικανότητα εξηγείται από την παρουσία φαινυλοπροπανοειδών οξέων που εστεροποιούν την απιγενίνη και που κατά τη βιβλιογραφία θεωρούνται ότι εμφανίζουν μεγαλύτερη αντιοξειδωτική δράση από αυτή μερικών γενινώ φλαβονοειδών
description: The isolation of five substanes was achieved by the assistance of polyamide and Sephadex LH-20 columns. We proved that they were apigenin esters of coumaric and caffeic acid. As far as the antioxidant activity of diethylether extract is concerned we used two methods (DPPH and chemiluminescence). Especially in the second method, the extract seemed to have bigger antioxidant activity than all the other standard solutions. This is explained because of the existence of phenylpropanoid acids which esterify the apigenin nucleous and according to the bibliography seems to have greater antioxidant activity in comparison to some flavonoid aglycons
Titanium corrosion in alkaline hydrogen peroxide environments

Publisher: name: University of British Columbia
Year: 2009

description: The corrosion of Grade 2 titanium in alkaline hydrogen peroxide environments has been studied by weight loss corrosion tests, electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR) measurements and potentiodynamic polarography. Calcium ions and wood pulp were investigated as corrosion inhibitors. In alkaline peroxide, the titanium corrosion rate increased with increasing pH, temperature, and hydrogen peroxide concentration. The corrosion controlling mechanism is thought to be the reaction of the oxide with the perhydroxyl ion. No evidence of thermodynamically stable calcium titanate was found in the surface film of test coupons exposed to calcium-inhibited alkaline peroxide solutions. Calcium inhibition is probably the result of low local alkali and peroxide concentrations at the metal surface produced by reaction of adsorbed calcium with hydrogen peroxide. It has been shown that the inhibiting effect of calcium is temporary, possibly through an effect of calcium on the chemical and/or physical stability of the surface oxide. Pulp is an effective and stable corrosion inhibitor. Raising the pulp concentration decreased the corrosion rate. The inhibiting effect of pulp may be related to the adsorption and interaction of the pulp fibers with H2O2, thereby decreasing the peroxide concentration and rendering the solution less corrosive. The presence of both pulp and calcium led to higher corrosion rates than obtained by either one inhibitor alone. Replacement of hydrofluoric acid with alkaline peroxide for pickling of titanium was investigated. Titanium corrosion rates in alkaline peroxide exceeded those obtained in the conventional hydrofluoric acid bath. General corrosion was observed with extensive roughening of the surface giving a dull gray appearance. Preferred dissolution of certain crystallographic planes was investigated through the corrosion of a titanium single crystal. Whereas the overall effect on the corrosion rate was small, the plane close to a prismatic plane orientation appeared to be the most corrosion resistant plane. The plane close to a basal plane orientation suffered from extensive pitting and roughening of the surface.

description: [abridged]We calculate multi-wavelength spectral energy distributions (SEDs) (spanning optical to millimeter wavelengths) from simulations of major galaxy mergers with black hole feedback which produce submillimeter bright galaxies (SMGs), using a self-consistent three-dimensional radiative transfer code. We reproduce correlations for local AGN observed in Spitzer Space Telescope's IRAC bands, and make definitive predictions for infrared X-ray correlations that should be testable by combining observations by Spitzer and the upcoming Herschel mission with X-ray surveys. Our dynamical approach allows us to directly correlate observed clustering in the data as seen in IRAC color-color plots with the relative amount of time the system spends in a region of color-color space. We also find that this clustering is positively correlated with the stars dominating in their contribution to the total bolometric luminosity. We present photo albums spanning the lifetime of SMGs, from their infancy in the pre-merger phase to the final stage as an elliptical galaxy, as seen in the observed $3.6 \micron$ and $450 \micron$ band to visually illustrate some of the morphological differences between mergers of differing orbital inclination and progenitor redshift. We find that SMGs are a broader class of systems than starbursts or quasars. We introduce a simple, heuristic classification scheme on the basis of the $L_{\rm IR}/L_{\rm x}$ ratios of these galaxies, which may be interpreted qualitatively as an evolutionary scheme, as these galaxies evolve in $L_{\rm IR}/L_{\rm x}$ while transiting from the pre-merger stage, through the quasar phase, to a merger remnant.

description: The two most intense wildfires of the last decade that took place in Canada in 2017 and Australia in 2019-2020 were followed by large injections of smoke in the stratosphere due to pyroconvection. It was discovered by Khaykin et al. (2020, doi:10.1038/s43247-020-00022-5) and Kablick et al. (2020, doi:10.1029/2020GL088101) that, after the Australian event, part of this smoke self-organized as anticyclonic confined vortices that rose in the mid-latitude stratosphere up to 35 km. Based on CALIOP observations and the ERA5 reanalysis, this new study analyzes the Canadian case and find, similarly, that a large plume penetrated the stratosphere by 12 August 2017 and got trapped within a meso-scale anticyclonic structure which travelled across the Atlantic. It then broke into three offsprings that could be followed until mid-October performing three round the world journeys and rising up to 23 km. We analyze the dynamical structure of the vortices produced by these two wildfires and demonstrate how they are maintained by the assimilation of data from instruments measuring the signature of the vortices in the temperature and ozone field. We propose that these vortices can be seen as bubbles of low absolute potential vorticity and smoke carried vertically across the stratification from the troposphere inside the middle stratosphere by their internal heating, against the descending flux of the Brewer-Dobson circulation.

description: In this work, we propose \texttt{TimeGrad}, an autoregressive model for multivariate probabilistic time series forecasting which samples from the data distribution at each time step by estimating its gradient. To this end, we use diffusion probabilistic models, a class of latent variable models closely connected to score matching and energy-based methods. Our model learns gradients by optimizing a variational bound on the data likelihood and at inference time converts white noise into a sample of the distribution of interest through a Markov chain using Langevin sampling. We demonstrate experimentally that the proposed autoregressive denoising diffusion model is the new state-of-the-art multivariate probabilistic forecasting method on real-world data sets with thousands of correlated dimensions. We hope that this method is a useful tool for practitioners and lays the foundation for future research in this area.

description:             With the advent of new technologies it witnessed significant positive influence on teaching, learning and research activities in universities. This has offered university libraries such ample opportunities to widely provide information resources in a variety of formats. However, researches have reported under underutilization of e-Resources in university despite the immense benefits to users. This research examined the extent and relationship of ICT literacy and ICT skills on use of e-Resources among postgraduate students’ in Federal University Dutsin-Ma, Nigeria. The study adopted a survey research design focused on a total population of all the 2100 postgraduate students of the University. Multistage sampling technique was used in the selection process of the targeted sample. A purposive selection and proportionate sampling technique was employed to extract the sample size of 325 postgraduate students from among various programs as being the respondents for the study. A validated questionnaire was used as instrument for data collection. The Cronbach’s alpha value for the constructs determined was 0.94 while the response rate reached 98%. Data were analyzed using descriptive statistics of mean and standard deviation on the extent of literacy and levels of skill on use of e-Resources; whereas Pearson Product Moment Correlation was carried out on the relationship among them. Findings revealed that there was a significant level of ICT literacy and ICT skills on the use of e-Resources as well as positive correlation between ICT literacy and ICT skills and use of e-Resources. Thus, it translated to significant influence of ICT literacy and ICT skills on the use of the e-Resources. Therefore the study concluded that utilization of e-Resources is promoted due to competent access and knowledge of information and communication technology among postgraduate students in the Federal University Dutsin-Ma, Nigeria

description: AgF$_2$ is a correlated charge-transfer insulator with properties remarkably similar to insulating cuprates which have raised hope that it may lead to a new family of unconventional superconductors upon doping. We use ab initio computations to study doping strategies leading to metallization. Because the upper Hubbard band is very narrow electron doping leads to undesired strongly self-trapped states (polarons). For the hole-doped case, polaron tendency is stronger than for cuprates but still moderate enough to expect that heavily doped compounds may become metallic. Since the strong electron lattice coupling originates in the strong buckling we study also an hypothetically flat allotrope and show that it has excellent prospect to become metallic. We compare the AgF2 behavior with that for the hole-doped conventional cuprate La$_2$CuO$_4$ and electron-doped Nd$_2$CuO$_4$. Our results show a clear path to achieve high temperature superconductivity in silver fluorides.

description: We study two dimensional soliton solutions in the $CP^2$ nonlinear $σ$-model with a Dzyaloshinskii-Moriya type interaction. First, we derive such a model as a continuous limit of the $SU(3)$ tilted ferromagnetic Heisenberg model on a square lattice. Then, introducing an additional potential term to the derived Hamiltonian, we obtain exact soliton solutions for particular sets of parameters of the model. The vacuum of the exact solution can be interpreted as a spin nematic state. For a wider range of coupling constants, we construct numerical solutions, which possess the same type of asymptotic decay as the exact analytical solution, both decaying into a spin nematic state.

Effects of Public Expenditure Growth on Economic Growth in Kenya
Creators: name: Julius Munene Magana
Publisher: name: Zenodo
Year: 2024

description: The effect of public expenditure growth on economic growth has given rise to conflicting views among economists. Some view a large government size as harmful to economic growth due to inefficiencies inherent in government. The other group of economists argues that a larger size of government is likely to enhance economic growth. Kenya’s public expenditure has been experiencing rapid growth since 1963, while GDP growth over the same period has not followed the same path. The main objective of this study was to examine the effects of government size on economic growth in Kenya for the period 1971-2021.The study used secondary data extracted from Economic Surveys, Statistical Abstracts published by the Kenya National bureau of Statistics and Kenya Institute of Public Policy Research for the period 1971-2021. The(Autoregressive distributed lag (ARDL) model was used to test the causal link between public expenditure growth and economic growth in Kenya during the period. The long run regression results showed that the effect of recurrent expenditure on economic growth was non-significant while the effect of development expenditure was significant. The study recommended government to slow recurrent expenditure to tamegrowth of public expenditure.

Quantum out-states holographically induced by asymptotic flatness: Invariance under spacetime symmetries, energy positivity and Hadamard property

description: This paper continues the analysis of the quantum states determined by the universal asymptotic structure of four-dimensional asymptotically flat vacuum spacetimes at null infinity M. It is now focused on the quantum state lambda_M, of a massles conformally coupled scalar field phi propagating in M. lambda_M is ``holographically'' induced in the bulk by the universal BMS-invariant state lambda at infinity scri of M. It is done by means of the correspondence between observables in the bulk and those on the boundary at null infinity discussed in previous papers. The induction is possible when some requirements are fulfilled, in particular the spacetime M and the associated unphysical one are globally hyperbolic and M admits future time infinity i^+. lambda_M coincides with Minkowski vacuum if M is Minkowski spacetime. It is now proved that, in the general case of a curved spacetime M, the state lambda_M enjoys the following further properties. (1) lambda_M is invariant under the group of isometries of the bulk spacetime M. (2) lambda_M fulfills a natural energy-positivity condition with respect to every notion of Killing time (if any) in the bulk spacetime M: If M admits a complete time-like Killing vector, the associated one-parameter group of isometries is represented by a strongly-continuous unitary group in the GNS representation of lambda_M. The unitary group has positive self-adjoint generator without zero modes in the one-particle space. (3) lambda_M is (globally) Hadamard in M and thus lambda_M can be used as starting point for perturbative renormalization procedure of QFT of phi in M.

description: We construct from Gaia eDR3 an extensive catalog of spatially resolved binary stars within $\approx$ 1 kpc of the Sun, with projected separations ranging from a few au to 1 pc. We estimate the probability that each pair is a chance alignment empirically, using the Gaia catalog itself to calculate the rate of chance alignments as a function of observables. The catalog contains 1.3 (1.1) million binaries with >90% (>99%) probability of being bound, including 16,000 white dwarf -- main sequence (WD+MS) binaries and 1,400 WD+WD binaries. We make the full catalog publicly available, as well as the queries and code to produce it. We then use this sample to calibrate the published Gaia DR3 parallax uncertainties, making use of the binary components' near-identical parallaxes. We show that these uncertainties are generally reliable for faint stars ($G\gtrsim 18$), but are underestimated significantly for brighter stars. The underestimates are generally $\le 30\%$ for isolated sources with well-behaved astrometry, but are larger (up to 80%) for apparently well-behaved sources with a companion within $\lesssim 4$ arcsec, and much larger for sources with poor astrometric fits. We provide an empirical fitting function to inflate published $σ_{\varpi}$ values for isolated sources. The public catalog offers wide ranging follow-up opportunities: from calibrating spectroscopic surveys, to precisely constraining ages of field stars, to the masses and the initial-final mass relation of white dwarfs, to dynamically probing the Galactic tidal field.

description: We present a global analysis of leptonic and semileptonic kaon decays data, including all recent results by BNL-E865, KLOE, KTeV, ISTRA+, and NA48. Experimental results are critically reviewed and combined, taking into account theoretical (both analytical and numerical) constraints on the semileptonic kaon form factors. This analysis leads to a very accurate determination of Vus and allows us to perform several stringent tests of the Standard Model.

description: This article examines the problem of Lithium-Sulfur (Li-S) battery state estimation. Such estimation is important for the online management of this energy-dense chemistry. The literature uses equivalent circuit models (ECMs) for Li-S state estimation. This article's main goal is to perform estimation using a physics-based model instead. This approach is attractive because it furnishes online estimates of the masses of individual species in a given Li-S cell. The estimation is performed using an experimentally-validated, computationally tractable zero-dimensional model. Reformulation converts this model from differential algebraic equations (DAEs) to ordinary differential equations (ODEs), simplifying the estimation problem. The article's first contribution is to show that this model has poor observability, especially in the low plateau region, where the low sensitivity of cell voltage to precipitated sulfur mass complicates the estimation of this mass. The second contribution is to exploit mass conservation to derive a reduced-order model with attractive observability properties in both high and low plateau regions. The final contribution is to use an unscented Kalman filter (UKF) for estimating internal Li-S battery states, while taking constraints on species masses into account. Consistent with the article's observability analysis, the UKF achieves better low-plateau estimation accuracy when the reduced-order model is used.
Mathematical modeling of microstructure and residual stress evolution in cast iron calender rolls
Creators: name: Maijer, Daan Michiel
Publisher: name: University of British Columbia
Year: 2009

description: Mathematical models have been developed for the purpose of predicting the evolution of microstructure and residual stress that develops during the manufacture of hypo-eutectic cast iron rolls for the paper industry. These include, a finite element based heat flow model to predict the evolution of temperature and microstructure, and a preliminary finite element based stress model to estimate the evolution of residual stress. Both models have been implemented in the commercial finite element code ABAQUS. To characterize the evolution of solidified microstructure, specialized routines, employing relationships describing nucleation and growth of equiaxed primary austenite, gray iron and white iron, were formulated and incorporated into an ABAQUS thermal model through user-defined subroutines. These relationships have been adapted and extended from a number of investigations describing equiaxed cast iron solidification presented in the literature. In addition, a preliminary columnar growth model was also implemented and tested to describe white iron growth. To describe the evolution of residual stress, a preliminary thermal stress model was developed to describe the evolution of stress and strain throughout the casting process. The preliminary stress model utilizes the temperature and microstructure predictions of the thermal model as input and incorporates phase and temperature dependent properties describing the elastic modulus, thermal dilatation, as well as, the strain rate independent, Von Mises, plastic deformation of the various phases. In order to validate the various components of the overall model, a series of measurements involving two industrial castings - a Quik-cup casting and a reduced scale roll casting - were undertaken to provide thermal, microstructural, and residual stress data for use in 'fine-tuning' and validating the mathematical models. Comparison of the predicted and measured temperatures show good overall agreement for both casting geometries. Microstructure predictions for the Quik-cup casting agree with the observed microstructure. However, in the reduced scale roll casting, key microstructure phenomena were inaccurately predicted with the equiaxed microstructure model. Improvements in the microstructure predictions were observed after the white iron columnar growth model was implemented. Residual stress predictions for the reduced scale roll casting show good overall agreement with the OD surface measurements. The results of this analysis show the importance and usefulness of developing the ability to predict residual stress and microstructure evolution in cast iron rolls.

description: 3-quasi-Sasakian manifolds were studied systematically by the authors in a recent paper as a suitable setting unifying 3-Sasakian and 3-cosymplectic geometries. This paper throws new light on their geometric structure which reveals to be generally richer compared to the 3-Sasakian subclass. In fact, it turns out that they are multiply foliated by four distinct fundamental foliations. The study of the transversal geometries with respect to these foliations allows us to link the 3-quasi-Sasakian manifolds to the more famous hyper-Kaehler and quaternionic-Kaehler geometries. Furthermore, we strongly improve the splitting results previously found; we prove that any 3-quasi-Sasakian manifold of rank 4l+1 is 3-cosymplectic and any 3-quasi-Sasakian manifold of maximal rank is 3-alpha-Sasakian.

Anisotropies and clustering of extragalactic cosmic rays

description: Deviations from isotropy have been a key tool to identify the sources and the primary type of cosmic rays (CRs) at low energies. We argue that anisotropies due to blind regions induced by the Galactic magnetic field, the cosmological Compton-Getting effect, medium-scale anisotropies reflecting the large-scale distribution of CR sources and the small-scale clustering of the CR arrival directions at the highest energies may play the same role for extragalactic CRs.

description: Advances in embyroculture media, have allowed the selection of embryos, with the greatest implantation potential and have led to an increase at the practive of blastocyst-stage embryo-transfer after IVF during the past years; however in order to make blastocyst transfer more effective and predictable it is necessary to identify those morphological characteristic of eocytes, zygotes, and embryos that affect blastulation. In the first part of this study are described the basic makes of human reproduction as well as, the main causes of infertility and the methods of IVF. In the second part, are described the collection and analysis of data from patients of "Biogenesis", IVF unit. The conclusions from the results of this statistical analysis support that certain morphological characteristics are associated with blastocyte development

description: Sensors nodes in WSNs’ applications are battery constrained thus innovative techniques are needed to eliminate energy inefficiency that shorten the network lifetime. There is dead node identification problem during the transmission of data because at that time path is not identified. Another problem is the network life time problem due to the redundancy. During the transmission energy is lossed, so there is energy consumption problem. There is NP-hard scheduling problem that we have seen in the literature survey. Another problem is the more bandwidth and less network life time problem. To implement Hybrid Algorithm for routing in Wireless sensor network using CH-leach and DEEC. To ACO and LEACH protocol on wireless sensor network using Clustering. CH-Leach Protocol, an approach of algorithm proposed, this proposed research used number of connection in cluster, and for each cluster head (CH) communicate with base station, however the selection of the cluster head based on the number of cluster on the network gird area, this method allow the network to adopted the best scenario to extend life time of the network, different ways of cluster are formed, in order to avoid the condition that one cluster will contain large of connection nodes and the rest is not, the maximum number of the cluster head is chosen in different scenario to test the network coverage. a series of experiments on different scenarios were implemented and tested. For energy consumption in wireless sensor network EEUC protocol, zone-divided and energy-balanced clustering routing protocol (ZECR) is used to enhance this work. In this paintings the higher performance is executed as a substitute then the present paintings due to the fact the present paintings is most effective relies upon on bodily shape however our paintings is carried out with logical paintings and the general output is 70%.

description: The DArk Matter Particle Explorer (DAMPE) is a satellite-borne detector for high-energy cosmic rays and $γ$-rays. To fully understand the detector performance and obtain reliable physical results, extensive simulations of the detector are necessary. The simulations are particularly important for the data analysis of cosmic ray nuclei, which relies closely on the hadronic and nuclear interactions of particles in the detector material. Widely adopted simulation softwares include the GEANT4 and FLUKA, both of which have been implemented for the DAMPE simulation tool. Here we describe the simulation tool of DAMPE and compare the results of proton shower properties in the calorimeter from the two simulation softwares. Such a comparison gives an estimate of the most significant uncertainties of our proton spectral analysis.
