description: Refraction of obliquely incident plane waves due to the interface of a vacuous half-space and a half-space occupied by a simply moving, nondissipative, isotropic dielectric-magnetic medium is considered, when the medium's velocity lies parallel to the interface and in the plane of incidence. Counterposition of the refracted wavevector and time-averaged Poynting vector occurs when the medium's velocity is sufficiently large in magnitude and makes an obtuse angle with the incident wavevector. The counterposition induced by relative motion occurs whether the refraction is negative or positive when the medium is at rest.

description: Magnetic skyrmions are whirl-like nano-objects with topological protection. When driven by direct currents (DC), skyrmions move but experience a transverse deflection. This so-called skyrmion Hall effect is often regarded a drawback for memory applications. Herein, we show that this unique effect can also be favorable for spintronic applications: We show that in a racetrack with a broken inversion symmetry, the skyrmion Hall effect allows to translate an alternating current (AC) into a directed motion along the track, like in a ratchet. We analyze several modes of the ratchet mechanism and show that it is unique for topological magnetic whirls. We elaborate on the fundamental differences compared to the motion of topologically trivial magnetic objects, as well as classical particles driven by periodic forces. Depending on the exact racetrack geometry, the ratchet mechanism can be soft or strict. In the latter case, the skyrmion propagates close to the efficiency maximum.

description: This paper introduces a sophisticated approach to network security, with a primary emphasis on utilizing deep learning for intrusion detection. In real-world scenarios, the high dimensionality of training data poses challenges for simple deep learning models and can lead to vanishing gradient issues with complex neural networks. Additionally, uploading network trafc data to a central server for training raises privacy concerns. To tackle these issues, the paper introduces a Residual Network (ResNet)-based deep learning model trained using a federated learning approach. The ResNet efectively tackles the vanishing gradient problem, while federated learning enables multiple Internet Service Providers (ISPs) or clients to engage in joint training without sharing their data with third parties. This approach enhances accuracy through collaborative learning while maintaining privacy. Experimental results on the X-IIoTID dataset indicate that the proposed model outperforms conventional deep learning and machine learning methods in terms of accuracy and other metrics used for evaluation. Specifcally, the proposed methodology achieved 99.43% accuracy.

description: High resolution ALMA observations revealed a variety of rich substructures in numerous protoplanetary disks. These structures consist of rings, gaps and asymmetric features. It is debated whether planets can be accounted for these substructures in the dust continuum. Characterizing the origin of asymmetries as seen in HD 163296 might lead to a better understanding of planet formation and the underlying physical parameters of the system. We test the possibility of the formation of the crescent-shaped asymmetry in the HD 163296 disk through planet-disk interaction. The goal is to obtain constraints on planet masses and eccentricities and disk viscosities. Two dimensional, multi-fluid, hydrodynamical simulations are performed with the FARGO3D code including three embedded planets. Dust is described with the pressureless fluid approach and is distributed over eight size bins. Resulting grids are post-processed with the radiative transfer code RADMC-3D and the CASA software to model synthetic observations. We find that the crescent-shaped asymmetry can be qualitatively modeled with a Jupiter mass planet at a radial distance of 48 au. Dust is trapped preferably in the trailing Lagrange point L5 with a mass of 10 to 15 earth masses. Increased values of eccentricity of the innermost Jupiter mass planet damages the stability of the crescent-shaped feature and does not reproduce the observed radial proximity to the first prominent ring in the system. Generally, a low level of viscosity ($α\leq 2\cdot10^{-3}$) is necessary to allow the existence of such a feature. Including dust feedback the leading point L4 can dominantly capture dust for dust grains with an initial Stokes number $\leq 3.6\cdot 10^{-2}$. The observational results suggest a negligible effect of dust feedback since only one such feature has been detected so far.

description: The goat is one of the early domesticated animals, earlier goat farming activity was limited to livelihood activity, but now it has become an important commercial activity. According to the 20th Livestock Census Report (2019), India has 148.88 Million goats, so India has 2nd highest population in the world followed by China (Table 1). Compared to the previous livestock census (2013) there is a 10.1% rise in the goat population in India, indicating steady growth in goat population and goat farming in India. Goats can adjust to a wide range of climatic conditions, rearing can be done in famine and drought areas. Goats are versatile and multipurpose animals because they will adapt under low fodder, low water, and extremely adverse climatic conditions and produce a variety of products meat, milk, kids, manure, and hide (Lad et al., 2017). A goat is known as a poor man's cow because it will produce milk, meat, and manure like a cow at a meager cost. Goats are docile, good-tempered, cooperative animals easy to rear by women, land less labour and children and they will thrive well on shrubs, bushes, and kitchen waste. They are known as moving ATMs they will provide financial assistance to farmers throughout the year in all situations (Risko and Csapo, 2019).

Direct control over the coin qubit is difficult to achieve in either cavity or circuit QED, but we show that a Hadamard coin flip can be effected via direct driving of the cavity, with the result that the walker jumps between circles in phase space but still exhibits quantum walk behavior over 15 steps.

A continuous, sub-Doppler-cooled atomic beam interferometer for inertial sensing

description: We present the first demonstration of an inertially sensitive atomic interferometer based on a continuous, rather than pulsed, atomic beam at sub-Doppler temperatures in three dimensions. We demonstrate 30\% fringe contrast in continuous, inertially sensitive interference fringes at interrogation time $T=6.7~\mathrm{ms}$ and a short-term phase measurement noise of $530~\mathrm{μrad /\sqrt{Hz}}$ as inferred from interference measurements. Atoms are delivered to the interferometer by a cold-rubidium source that produces a high flux of atoms at temperature $\leq15~\mathrmμ K$ in three dimensions while reducing near-resonance fluorescence in the downstream path of the atoms. We describe the optimization of the interrogating Raman beams to achieve high contrast, and validate interferometer operation through comparison with measurements by commercial accelerometers. We further provide a demonstration of zero-dead-time phase-shear readout of atom interferometer phase, achieving a measurement rate up to 160~Hz. This demonstration lays the groundwork for future gyroscope/accelerometer sensors that measure continuously, with both high bandwidth and high sensitivity, and on dynamic platforms.

description: We report the simultaneous observations of the prompt emission in the gamma-ray and hard X-ray bands by the Swift-BAT and the KONUS-Wind instruments of the short-hard burst, GRB 060313. The observations reveal multiple peaks in both the gamma-ray and hard X-ray bands suggesting a highly variable outflow from the central explosion. We also describe the early-time observations of the X-ray and UV/Optical afterglows by the Swift XRT and UVOT instruments. The combination of the X-ray and UV/Optical observations provide the most comprehensive lightcurves to date of a short-hard burst at such an early epoch. The afterglows exhibit complex structure with different decay indices and flaring. This behavior can be explained by the combination of a structured jet, radiative loss of energy, and decreasing microphysics parameters occurring in a circum-burst medium with densities varying by a factor of approximately two on a length scale of 10^17 cm. These density variations are normally associated with the environment of a massive star and inhomogeneities in its windy medium. However, the mean density of the observed medium (n approximately 10^−4 cm^3) is much less than that expected for a massive star. Although the collapse of a massive star as the origin of GRB 060313 is unlikely, the merger of a compact binary also poses problems for explaining the behavior of this burst. Two possible suggestions for explaining this scenario are: some short bursts may arise from a mechanism that does not invoke the conventional compact binary model, or soft late-time central engine activity is producing UV/optical but no X-ray flaring.

description: This paper reports detections of H$α$ emission and stellar continuum out to approximately 30 physical kpc, and H$α$ directionality in the outskirts of H$α$-emitting galaxies (H$α$ emitters) at $z=0.4$. This research adopts narrow-band selected H$α$ emitters at $z=0.4$ from the emission-line object catalog by Hayashi et al. (2020), which is based on data in the Deep and Ultradeep layers of the Hyper Suprime-Cam Subaru Strategic Program. Deep narrow- and broad-band images of 8625 H$α$ emitters across 16.8 deg$^2$ enable us to construct deep composite emission-line and continuum images. The stacked images show diffuse H$α$ emission (down to $\sim5\times10^{-20}$ erg~s$^{-1}$cm$^{-2}$arcsec$^{-2}$) and stellar continuum (down to $\sim5\times10^{-22}$ erg~s$^{-1}$cm$^{-2}$A$^{-1}$arcsec$^{-2}$), extending beyond 10 kpc at stellar masses $>10^9$ M$_\odot$, parts of which may originate from stellar halos. Those radial profiles are broadly consistent with each other. In addition, we obtain a dependence of the H$α$ emission on the position angle because relatively higher H$α$ equivalent width has been detected along the minor-axis towards galaxy disks. While the H$α$ directionality could be attributed to biconical outflows, further research with hydrodynamic simulations is highly demanded to pin down the exact cause.

X-ray flux in the SED modelling: An application of X-CIGALE in the XMM-XXL field

description: X-CIGALE, built upon the spectral energy distribution (SED) code of CIGALE, implements important new features: The code accounts for obscuring material in the polars of the AGN and has the ability to fit X-ray fluxes. In this work, we use ~2500 spectroscopic, X-ray AGN from the XMM-XXL-North field and examine the improvements the new features bring in the SED modelling analysis. Based on our results, X-CIGALE successfully connects the X-ray with the UV luminosity in the whole range spanned by our sample (log Lx(2-10 keV) = (42 - 46) erg/s). The addition of the new features globally improves the efficiency of X-CIGALE in the estimation and characterization of the AGN component. The classification into type 1 and type 2 based on their inclination angle is improved, especially at redshifts lower than 1. The statistical significance of the AGN fraction, fracAGN, measurements is increased, in particular for luminous X-ray sources (log LX > 45 erg/s). These conclusions hold under the condition that (mid-) IR photometry is available in the SED fitting process. The addition of polar dust increases the AGN fraction and the efficiency of the SED decomposition to detect AGN among X-ray selected sources. X-CIGALE estimates a strong AGN (fracAGN > 0.3) in more than 90% of the infrared selected AGN and 75% of X-ray detected AGN not selected by IR colour criteria. The latter drops to ~50% when polar dust is not included. The ability of X-CIGALE to include X-ray information in the SED fitting process can be instrumental in the optimal exploitation of the wealth of data that current (eROSITA) and future (ATHENA) missions will provide us.

description: The transmission of Lyman-α (Lyα) in the spectra of distant quasars depends on the density, temperature, and ionization state of the intergalactic medium (IGM). Therefore, high-redshift (z > 5) Lyα forests could be invaluable in studying the late stages of the epoch of reionization (EoR), as well as properties of the sources that drive it. Indeed, high-quality quasar spectra have now firmly established the existence of large-scale opacity fluctuations at z > 5, whose physical origins are still debated. Here we introduce a Bayesian framework capable of constraining the EoR and galaxy properties by forward-modelling the high-z Lyα forest. Using priors from galaxy and CMB observations, we demonstrate that the final overlap stages of the EoR (when >95% of the volume was ionized) should occur at z < 5.6, in order to reproduce the large-scale opacity fluctuations seen in forest spectra. However, it is the combination of patchy reionization and the inhomogeneous UV background that produces the longest Gunn-Peterson troughs. Lyα forest observations tighten existing constraints on the characteristic ionizing escape fraction of galaxies, with the combined observations suggesting f_{\rm esc} \approx 7^4_3%, and disfavoring a strong evolution with the galaxy's halo (or stellar) mass.

description: The article discusses the problems of using authentic materials on teaching foreign languages. Using authentic materials in the class can be a useful tool to motivate pupils and make them feel comfortable using the foreign language. Authentic materials, if used properly in authentic learning environments, can have lots of uses in foreign language teaching though they are not specifically designed to teach a foreign language. For this reason, foreign language teachers should act as a guide for the students to interact with the authentic materials in constructivist learning environments. In addition, learning environments in which authentic materials are used should be organized when training prospective foreign language teachers to set an example for the teachers of the future to use authentic materials in their own classrooms. In that way, prospective teachers will have a chance to see and experience, themselves, the advantages of these materials and points to consider when using them. The aim of the present study is to focus on the importance and the uses of authentic materials in foreign language teacher training program and to come up with some suggestions concerning the matter

Publisher: name: University of British Columbia
Year: 2009

description: Information technologies (IT) have drastically transformed many business activities in the past 30 years. Among the numerous business activities in organizations, the budget preparation process plays a very important role. Although there are many developed systems available to automate certain aspects of the budgeting process, there is much more that can be done. This thesis studies the budgeting process and certain behavioral factors involved in the preparation of the budget. Knowing the complications inherent in budgeting, effort has been directed towards automating the mechanistic portion of the process; narrowing down the differences; and identifying the sources of discrepancy by using a computer-based system. Based on an algorithm derived from a manually solved budgeting case, the requirements of automation were studied, a computer based system was developed and tested. In addition, directions for future studies are suggested in this thesis.

description: We consider non-standard cosmological models in which the late decay of a scalar field $ϕ$ reheats the Universe to a low reheating temperature, between 5 MeV and the standard freeze-out temperature of neutralinos of mass $m_χ$. We point out that in these models all neutralinos with standard density $Ω_{\rm std} \gtrsim 10^{-5} (100 {\rm GeV}/m_χ)$ can have the density of cold dark matter, provided the right combination of the following two parameters can be achieved in the high energy theory: the reheating temperature, and the ratio of the number of neutralinos produced per $ϕ$ decay over the $ϕ$ field mass. We present the ranges of these parameters where a combination of thermal and non-thermal neutralino production leads to the desired density, as functions of $Ω_{\rm std}$ and $m_χ$.

description: We prove that every bounded Lipschitz function F on a subset Y of a length space X admits a tautest extension to X, i.e., a unique Lipschitz extension u for which Lip_U u = Lip_{boundary of U} u for all open subsets U of X that do not intersect Y. This was previously known only for bounded domains R^n, in which case u is infinity harmonic, that is, a viscosity solution to Delta_infty u = 0. We also prove the first general uniqueness results for Delta_infty u = g on bounded subsets of R^n (when g is uniformly continuous and bounded away from zero), and analogous results for bounded length spaces. The proofs rely on a new game-theoretic description of u. Let u^epsilon(x) be the value of the following two-player zero-sum game, called tug-of-war: fix x_0=x \in X minus Y. At the kth turn, the players toss a coin and the winner chooses an x_k with d(x_k, x_{k-1})< epsilon. The game ends when x_k is in Y, and player one's payoff is F(x_k) - (epsilon^2/2) sum_{i=0}^{k-1} g(x_i) We show that the u^εconverge uniformly to u as epsilon tends to zero. Even for bounded domains in R^n, the game theoretic description of infinity-harmonic functions yields new intuition and estimates; for instance, we prove power law bounds for infinity-harmonic functions in the unit disk with boundary values supported in a delta-neighborhood of a Cantor set on the unit circle.

description: Neutron Stars (NSs) are compact stellar objects that are stable solutions in General Relativity. Their internal structure is usually described using an equation of state that involves the presence of ordinary matter and its interactions. However there is now a large consensus that an elusive sector of matter in the Universe, described as dark matter, remains as yet undiscovered. In such a case, NSs should contain both, baryonic and dark matter. We argue that depending on the nature of the dark matter and in certain circumstances, the two matter components would form a mixture inside NSs that could trigger further changes, some of them observable. The very existence of NSs constrains the nature and interactions of dark matter in the Universe

Publisher: name: F1000Research
Year: 2015

description: A large number of researchers are engaged in screening crude extracts of natural origin for a variety of bioactivities. The first crucial step in this exercise is preparation of extract. Though a multitude of extraction methods are available, selection of the correct method is always not easy, as always the method providing high extraction yield is not the best in terms of efficacy.  In recent times, methods suitable for heat-labile phytoconstituents are being increasingly preferred. Among them microwave assisted extraction (MAE) has emerged as a promising one. We have been employing the MAE method for preparation of plant seed extracts since last 8-9 years, and we have found this method suitable for extraction of antioxidant, antibacterial, antifungal, anti-biofilm, and anti-quorum sensing compounds from plant seeds. In a comparative study of various extraction methods for extraction of antioxidant and antibacterial compounds from plant seeds, performed by us, MAE scored better on certain parameters than the traditional Soxhlet method. MAE has been considered as a method of choice for fast extraction of plant phenolics. This presentation is a concise account of our research involving MAE over past few years, emphasizing the appropriateness of promoting widespread use of this cost-effective and simple method among the researchers working in the area of bioactive natural products.

Theoretical analysis of the role of complex transition dipole phase in XUV transient-absorption probing of charge migration

description: We theoretically investigate the role of complex dipole phase in the attosecond probing of charge migration. The iodobromoacetylene ion (ICCBr$^+$) is considered as an example, in which one can probe charge migration by accessing both the iodine and bromine ends of the molecule with different spectral windows of an extreme-ultraviolet (XUV) pulse. The analytical expression for transient absorption shows that the site-specific information of charge migration is encoded in the complex phase of cross dipole products for XUV transitions between the I-$4d$ and Br-$3d$ spectral windows. Ab-initio quantum chemistry calculations on ICCBr$^+$ reveal that there is a constant $π$ phase difference between the I-$4d$ and Br-$3d$ transient-absorption spectral windows, irrespective of the fine-structure energy splittings. Transient absorption spectra are simulated with a multistate model including the complex dipole phase, and the results correctly reconstruct the charge-migration dynamics via the quantum beats in the two element spectral windows, exhibiting out-of-phase oscillations.

description: We characterize the response of isolated single- (SWNT) and multi-wall (MWNT) carbon nanotubes and bundles to static electric fields using first-principles calculations and density-functional theory. The longitudinal polarizability of SWNTs scales as the inverse square of the band gap, while in MWNTs and bundles it is given by the sum of the polarizabilities of the constituent tubes. The transverse polarizability of SWNTs is insensitive to band gaps and chiralities and is proportional to the square of the effective radius; in MWNTs the outer layers dominate the response. The transverse response is intermediate between metallic and insulating, and a simple electrostatic model based on a scale-invariance relation captures accurately the first-principles results. Dielectric response of non-chiral SWNTs in both directions remains linear up to very high values of applied field.

THE WAY OF IMPROVING READING AND WRITING SKILLS DURING THE LESSONS
Creators: name: Kamola Abdullayevna Shokarimova
Publisher: name: Academic research in educational sciences
Year: 2021
Subjects: Prediction
Cohesive devices
Expository Writing
Persuasive Writing
Intensive Reading

description: Reading and writing largely depend upon the same skills. Spelling and singleword reading rely on the same underlying knowledge, and instruction and practice in one should aid the development of the other. For instance, the ability to link sounds together to construct words is reinforced when students read and write the same words. Furthermore, writing instruction improves reading comprehension and the teaching of writing skills — such as grammar and spelling lessons — reinforce reading skills. Research suggests that reading and writing skills are best developed when taught and practiced in conjunction

Complex variables for separation of Hamilton-Jacobi equation on real pseudo-Riemannian manifolds
Creators: name: Degiovanni, Luca
name: Rastelli, Giovanni
Publisher: name: arXiv
Year: 2006
Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: In this paper the geometric theory of separation of variables for time-independent Hamilton-Jacobi equation is extended to include the case of complex eigenvalues of a Killing tensor on pseudo-Riemannian manifolds. This task is performed without to complexify the manifold but just considering complex-valued functions on it. The simple formalism introduced allows to extend in a very natural way the classical results on separation of variables (including Levi-Civita criterion and Stackel-Eisenhart theory) to the complex case. Orthogonal variables only are considered.

Anticipating hephzibah rediscovering the fourth gospel
Creators: name: Tyson, Janet Sylvia Bernadette
Publisher: name: University of British Columbia
Year: 2009

description: The thesis presented in this paper involves the re-evaluation of the Fourth Gospel's narrative in light of intertextual analysis. The aim is to demonstrate how the author of this gospel has exploited Israelite scriptural and historic tradition to depict the Jesus Movement as one motivated by a desire to see Israel reinstated as the elect of Yahweh. This, it is shown, is manifested in a series of highly symbolic actions which echo the pattern of Ezek 16; this pattern reveals the cycle of Israel as Yahweh's "bride". Near the end of this cycle, the Movement takes on a priestly perspective, revealing the establishment of a new, symbolically purified priesthood.

The refractive index of the relic gravitons and the nHz band

description: If the refractive index of the relic gravitons increases during a conventional stage of inflationary evolution the spectral energy density is blue at intermediate frequencies above the fHz and then flattens out after a knee that is typically smaller than the mHz. We investigate here the conditions leading to a sufficiently large spectral energy density in the nHz range where some peculiar signatures observed with the pulsar timing arrays have been recently attributed to cosmic gravitons. If these potential evidences are combined with the most recent bounds provided by wide-band interferometers in the audio range (i.e. between few Hz and the kHz) the allowed regions of the parameter space are compatible with both determinations and also with all the other constraints associated with the background of relic gravitons produced during inflation. The present analysis suggests that the pulsar timing arrays are sensitive to the evolution of the refractive index during the early stages of the inflationary evolution. This physical interpretation of the preliminary empirical evidence is distinguishable from other perspectives since the high-frequency normalization, the blue spectral index and the tensor to scalar ratio cannot be independently assigned but are all related to the frequency of the knee that is ultimately determined by the competition between the rate of evolution of the refractive index and the slow-roll corrections.
