description: We present a detailed abundance analysis based on high resolution and high signal-to-noise spectra of eight extremely metal poor (EMP) stars with [Fe/H] < -3.5$ dex, four of which are new. Only stars with 4900 < Teff< 5650 K are included. Two stars of the eight are outliers in each of several abundance ratios. The most metal poor star in this sample, HE1424-0241, has [Fe/H] ~ -4 dex and is thus among the most metal poor stars known in the Galaxy. It has highly anomalous abundance ratios unlike those of any other known EMP giant, with very low Si, Ca and Ti relative to Fe, and enhanced Mn and Co, again relative to Fe. Only (low) upper limits for C and N can be derived from the non-detection of the CH and NH molecular bands. HE0132$-$2429, another sample star, has excesses of N and Sc with respect to Fe. The strong outliers in abundance ratios among the Fe-peak elements in these C-normal stars, not found at somewhat higher metallicities, are definitely real. They suggest that at such low metallicities we are beginning to see the anticipated and long sought stochastic effects of individual supernova events contributing to the Fe-peak material within a single star. A detailed comparison of the results of the analysis procedures adopted by our 0Z project compared to those of the First Stars VLT Large Project finds a systematic difference for [Fe/H] of ~0.3 dex, our values always being higher.

description: The effects of discreteness arising from the use of the N-body method on the accuracy of simulations of cosmological structure formation are not currently well understood. After a discussion of how the relevant discretisation parameters introduced should be extrapolated to recover the Vlasov-Poisson limit, we study numerically, and with analytical methods we have developed recently, the central issue of how finite particle density affects the precision of results. In particular we focus on the power spectrum at wavenumbers around and above the Nyquist wavenumber, in simulations in which the force resolution is taken smaller than the initial interparticle spacing. Using simulations of identical theoretical initial conditions sampled on four different "pre-initial" configurations (three different Bravais lattices, and a glass) we obtain a {\it lower bound} on the real discreteness error. With the guidance of our analytical results, we establish with confidence that the measured dispersion is not contaminated either by finite box size effects or by subtle numerical effects. Our results show notably that, at wavenumbers {\it below} the Nyquist wavenumber, the dispersion increases monotonically in time throughout the simulation, while the same is true above the Nyquist wavenumber once non-linearity sets in. For normalizations typical of cosmological simulations, we find lower bounds on errors at the Nyquist wavenumber of order of a percent, and larger above this scale. The only way this error may be reduced below these levels at these scales, and indeed convergence to the physical limit firmly established, is by extrapolation, at fixed values of the other relevant parameters, to the regime in which the mean comoving interparticle distance becomes less than the force smoothing scale.

description: Heusler alloys that undergo martensitic transformation in ferromagnetic state are of increasing scientific and technological interest. These alloys show large magnetic field induced strains upon martensitic phase change thus making it a potential candidate for magneto-mechanical actuation. The crystal structure of martensite is an important factor that affects both the magnetic anisotropy and mechanical properties of such materials. Moreover, the local chemical arrangement of constituent atoms is vital in determining the overall physical properties. Ni$_{50}$Mn$_{35}$In$_{15}$ is one such ferromagnetic shape memory alloy that displays exotic properties like large magnetoresistance at moderate field values. In this work, we present the extended x-ray absorption fine-structure measurements (EXAFS) on the bulk Ni$_{50}$Mn$_{35}$In$_{15}$ which reveal the local structural change that occurs upon phase transformation. The change in the bond lengths between different atomic species helps in understanding the type of hybridization which is an important factor in driving such Ni-Mn based systems towards martensitic transformation.

description: This work provides the first full set of vibrational and rotational spectral data needed to aid in the detection of AlH$_3$OH$_2$, SiH$_3$OH, and SiH$_3$NH$_2$ in astrophysical or simulated laboratory environments through the use of quantum chemical computations at the CCSD(T)-F12b level of theory employing quartic force fields for the three molecules of interest. Previous work has shown that SiH$_3$OH and SiH$_3$NH$_2$ contain some of the strongest bonds of the most abundant elements in space. AlH$_3$OH$_2$ also contains highly abundant atoms and represents an intermediate along the reaction pathway from H$_2$O and AlH$_3$ to AlH$_2$OH. All three of these molecules are also polar with AlH$_3$OH$_2$ having the largest dipole of 4.58 D and the other two having dipole moments in the 1.10-1.30 D range, large enough to allow for the detection of these molecules in space through rotational spectroscopy. The molecules also have substantial infrared intensities with many of the frequencies being over 90 km mol$^{-1}$ and falling within the currently uncertain 12-17 $μ$m region of the spectrum. The most intense frequency for AlH$_3$OH$_2$ is $ν_9$ which has an intensity of 412 km mol$^{-1}$ at 777.0 cm$^{-1}$ (12.87 $μ$m). SiH$-3$OH has an intensity of 183 km mol$^{-1}$ at 1007.8 cm$^{-1}$ (9.92 $μ$m) for $ν_5$, and SiH$_3$NH$_2$ has an intensity of 215 km mol$^{-1}$ at 1000.0 cm$^{-1}$ (10.00 $μ$m) for $ν_7$.

description: We determine the feasibility of detecting analogue Hawking radiation in a Bose-Einstein condensate in the presence of atom loss induced heating. We find that phonons created by three-body losses overshadow those due to analogue Hawking radiation. To overcome this problem, three-body losses may have to be suppressed, for example as proposed by Search et al. [Phys. Rev. Lett. 92 140401 (2004)]. The reduction of losses to a few percent of their normal rate is typically sufficient to suppress the creation of loss phonons on the time scale of a fast analogue Hawking phonon detection.

Extending Soft-Collinear-Effective-Theory to describe hard jets in dense QCD media

description: An extension to the Soft-Collinear-Effective Theory (SCET) description of hard jets is motivated to include the leading contributions between the propagating partons within the jet with partons radiated from a dense extended medium. The resulting effective Lagrangian, containing both a leading and a power suppressed (in the hard scale $Q^2$) contribution, arises primarily from interactions between the hard collinear modes in the jet with Glauber modes from the medium. In this first attempt, the interactions between the hard jet and soft and collinear partonic modes have been ignored, in an effort to focus solely on the interactions with the Glauber modes. While the effect of such modes on vacuum cross sections are suppressed by powers of the hard scale compared to the terms from the SCET Lagrangian, such sub-leading contributions are enhanced by the extent of the medium and result in measurable corrections. The veracity of the derived Lagrangian is checked by direct comparison with known results from full QCD calculations of two physical observables: the transverse momentum broadening of hard jets in dense media and a reanalysis of the transverse momentum dependent parton distribution function (TMDPDF).

description: With the upcoming extremely large telescopes (ELTs), the volume, mass, and cost of the associated spectrographs will scale with the telescope diameter. Astrophotonics offers a unique solution to this problem in the form of single-mode fiber-fed diffraction-limited spectrographs on a chip. These highly miniaturized chips offer great flexibility in terms of coherent manipulation of photons. Such photonic spectrographs are well-suited to disperse the light from directly imaged planets (post-coronagraph, collected using a single-mode fiber) to characterize exoplanet atmospheres. Here we present the results from a proof-of-concept high-resolution astrophotonic spectrograph using the arrayed waveguide gratings (AWG) architecture. This chip uses the low-loss SiN platform (SiN core, SiO$_2$ cladding) with square waveguides (800 nm $\times$ 800 nm). The AWG has a measured resolving power ($λ/δλ$) of $\sim$ 12,000 and a free spectral range (FSR) of 2.8 nm. While the FSR is small, the chip operates over a broad band (1200 $-$ 1700 nm). The peak on-chip throughput (excluding the coupling efficiency) is $\sim$40\% (- 4 dB) and the overall throughput (including the coupling loss) is $\sim$ 11\% (- 9.6 dB) in the TE mode. Thanks to the high-confinement waveguide geometry, the chip is highly miniaturized with a size of only 7.4 mm $\times$ 2 mm. This demonstration highlights the utility of SiN platform for astrophotonics, particularly, the capability of commercial SiN foundries to fabricate ultra-small, high-resolution, high-throughput AWG spectrographs on a chip suitable for both ground- and space-based telescopes.

description: This study examines the Palestine-Israel conflict’s effects on Middle Eastern financial markets, including conventional and Islamic indices. Employing wavelet cross-correlation, global VAR (GVAR), and Granger causality analyses, we identify complex patterns in pre-conflict geopolitical risk (GPR) and stock returns, including diverse lead/lag behaviors and amplitude fluctuations. Post-conflict, these dynamics show smoother adjustments and stronger cross-correlations. The pre-conflict wavelet GVAR analysis reveals country-specific reactions to anticipated GPR shocks, marked by asymmetric responses starting around 20 days post-shock and varying across nations. This period also features significant shock spillovers in stock returns, both positive and negative. During the conflict, initial reactions include substantial spikes in raw stock returns, suggesting possible co-crash scenarios. These evolve into predominantly positive short-term shock spillovers, with medium and long-term responses suggesting stock markets as potential safe havens. Lastly, wavelet Granger causality analysis reveals bidirectional causality between GPR and stock returns over the long term, with specific countries showing varied causality patterns during the conflict. The inclusion of Islamic indices demonstrates homogeneous responses to GPR shocks, similar to conventional markets, highlighting the integrated nature of these markets. This study underscores the complex temporal dynamics of market responses to geopolitical shocks and provides insights for policymakers and investors.

description: Here, we present an astrophotonic spectrograph in the near-IR H-band (1.45 -1.65 $μm$) and a spectral resolution ($λ/δλ$) of 1500. The main dispersing element of the spectrograph is a photonic chip based on Arrayed-Waveguide-Grating technology. The 1D spectrum produced on the focal plane of the AWG contains overlapping spectral orders, each spanning a 10 nm band in wavelength. These spectral orders are cross-dispersed in the perpendicular direction using a cross-dispersion setup which consists of collimating lenses and a prism and the 2D spectrum is thus imaged onto a near-IR detector. Here, as a proof of concept, we use a few-mode photonic lantern to capture the light and feed the emanating single-mode outputs to the AWG chip for dispersion. The total size of the setup is 50$\times$30$\times$20 cm$^3$, nearly the size of a shoebox. This spectrograph will pave the way for future miniaturized integrated photonic spectrographs on large telescopes, particularly for building future photonic multi-object spectrographs.

description: This comprehensive study delves into the nuanced relationship between public health initiatives, particularly non-pharmaceutical interventions (NPIs), and their economic repercussions amid the COVID-19 pandemic. Employing a dataset spanning from February 2020 to June 2021, this study conducts a comprehensive analysis of the interplay between democracy, Nonpharmaceutical Interventions (NPIs) and economic outcomes, with a particular focus on unemployment rates. The research findings indicate a nuanced interaction between democracy and the implementation of NPIs, suggesting that democratic contexts do not only enhance the NPI measures’ overall efficacy in curbing the pandemic but also preserve economic stability, particularly by mitigating the adverse effects on unemployment rates. Thus, nations with their robust economic reserves and democratic infrastructures, have effectively employed NPIs to protect public health while mitigating economic downturns, aligning with the ‘Zero-COVID’ strategy. The study also presents a compelling argument that nations under economic strain can still benefit from NPIs, provided they operate within a democratic framework. This assertion is supported by evidence suggesting that democratic governance plays a pivotal role in the effective implementation of NPIs, facilitating both health crisis management and economic stability. This study explores the complex relationship between nonpharmaceutical interventions (NPIs) and their economic impact during the COVID-19 pandemic, particularly focusing on how democratic governance influences this dynamic. Using data from 50 countries over 17 months, the paper demonstrates that NPIs, such as lockdowns and social distancing, effectively mitigated the spread of COVID-19. Importantly, it reveals that democratic nations, due to their governance structures, were better equipped to balance public health imperatives and economic stability, especially in mitigating unemployment. The research emphasizes the critical role of democracy in ensuring effective implementation of NPIs while reducing the adverse economic consequences. The significance of this work lies in its contribution to understanding how different governance models influenced pandemic management. By offering insights into the interplay between health and economic outcomes, the findings provide valuable lessons for policymakers, especially in the context of managing future public health crises. The study also challenges the perception that public health and economic objectives are mutually exclusive, instead advocating for a more integrated approach that ensures both health preservation and economic resilience.

description: Every cusped, finite-volume hyperbolic three-manifold has a canonical decomposition into ideal polyhedra. We study the canonical decomposition of the hyperbolic manifold obtained by filling some (but not all) of the cusps with solid tori: in a broad range of cases, generic in an appropriate sense, this decomposition can be predicted from that of the unfilled manifold. As an example, we treat all hyperbolic fillings on one cusp of the Whitehead link complement.

description: We investigate the Quantum Resonance (QR) regime of a periodically kicked atomic Bose-Einstein condensate. We find that the clearest indicator of the nonlinear dynamics is a surprisingly abrupt cut-off which appears on the main "Talbot time" QR. We show that this is due and excitation path combining both Beliaev and Landau processes, with some analogies to nonlinear self-trapping. Investigation of dynamical instability reveals further symptoms of nonlinearity such as a regime of exponential oscillations.

description: Starting from the rigorous quantum-field-theory formalism we derive a formula for the screened conductivity designed to study the coupling of light with elementary electron excitations and the ensuing electromagnatic modes in two-dimensional (2D) semiconductors. The latter physical quantity consists of three fully separable parts, namely intraband, interband, and ladder conducivities, and is calculated beyond the random phase approximation as well as from first principles. By using this methodology, we study the optical absorption spectra in 2D black phosphorous, so-called phosphorene, as a function of the concentration of electrons injected into the conduction band. The mechanisms of phosphorene exciton quenching versus doping are studied in detail. It is demonstrated that already small doping levels ($n\sim 10^{12}\,{\rm cm}^{-2}$) lead to a radical drop in the exciton binding energy, i.e., from $600\,{\rm meV}$ to $128\,{\rm meV}$. The screened conductivity is applied to study the collective electromagnetic modes in doped phosphorene. It is shown that the phosphorene transversal exciton hybridizes with free photons to form a exciton-polariton. This phenomenon is experimentally observed only for the case of confined electromagnetic microcavity modes. Finally, we demonstrate that the energy and intensity of anisotropic 2D plasmon-polaritons can be tuned by varying the concentration of injected electrons.

description: PEDICULIDAE
 Louse­borne pathogens such as Rickettsia prowazekii da Rocha­Lima, the agent of epidemic typhus, caused massive epidemics during most European wars and were well documented throughout the Old World. Louse­borne pathogens could have been endemic to the New World prior to the arrival of Europeans, but there are no records of any distinctive epidemics. Both head and body lice were found on the bodies of Peruvian mummies that predated the arrival of Europeans (Rick et al. 2002). A zoonotic strain of R. prowazekii caused isolated typhus cases in Georgia and North Carolina, but no cases have been reported from South Carolina (McDade 1987; Reynolds et al. 2003). These lice are cosmopolitan in distribution. The taxonomy of the Pediculidae is a controversial issue. Some authors separate Pediculus humanus Linnaeus and Pediculus capitus De Geer into different species whereas others consider them subspecies. Leo et al. (2002) using a limited 524 base pair sequence of mitochondrial DNA were unable to differentiate the two species and suggested head and body lice could be strains of a single species. Other genes or longer sequences could yield differing results. The differentiation of these two lice is important because only the human body louse is a known vector of pathogens in nature. The collectors of all human lice are omitted to avoid possible embarrassment to the infested individuals. All Pediculidae were collected from Homo sapiens Linnaeus.

description: The emergent spectra of close-in, giant exoplanets ("hot Jupiters") are expected to be distinct from those of self-luminous objects with similar effective temperatures because hot Jupiters are primarily heated from above by their host stars rather than internally from the release of energy from their formation. Theoretical models predict a continuum of dayside spectra for hot Jupiters as a function of irradiation level, with the coolest planets having absorption features in their spectra, intermediate-temperature planets having emission features due to thermal inversions, and the hottest planets having blackbody-like spectra due to molecular dissociation and continuum opacity from the H- ion. Absorption and emission features have been detected in the spectra of a number of individual hot Jupiters, and population-level trends have been observed in photometric measurements. However, there has been no unified, population-level study of the thermal emission spectra of hot Jupiters such as has been done for cooler brown dwarfs and transmission spectra of hot Jupiters. Here we show that hot Jupiter secondary eclipse spectra centered around a water absorption band at 1.4 microns follow a common trend in water feature strength with temperature. The observed trend is broadly consistent with model predictions for how the thermal structures of solar-composition planets vary with irradiation level. Nevertheless, the ensemble of planets exhibits some degree of scatter around the mean trend for solar composition planets. The spread can be accounted for if the planets have modest variations in metallicity and/or elemental abundance ratios, which is expected from planet formation models. (abridged abstract)

description: This work is devoted to the development of a micro-service application of a knowledge base based on inter-user interaction. The paper discusses the types of ap-plication architecture, as well as various technologies and principles used in the crea-tion of services. Goals and objectives have been set for the system being developed. The final part describes the development of a prototype of a microservice application, where the creation of several independent services that are part of the application is considered in turn. Also, after the development, the process of testing both individual services and the entire system is shown.
Lorentz symmetries and primary constraints in covariant teleparallel gravity

description: In this article we explore local Lorentz transformations in theories of gravity based on the teleparallel formalism. For the teleparallel equivalent of general relativity (TEGR), the spin connection plays no role in the equations of motion, and therefore it is possible to simply put it equal to zero with no change in physical quantities, and then the theory is formulated purely in terms of the tetrad field which can be freely chosen in any way. In nonlinear modifications of TEGR, this is a more intricate issue, and vanishing spin connection is then the Weitzenböck gauge choice which imposes restrictions on the choice of tetrad. This has led to considering the so-called covariant formulation of $f(T)$ gravity. We examine the primary constraints arising when passing to the Hamiltonian framework, and compute their algebra. We show that the problems of local Lorentz symmetry breaking still appear in this formulation, even if in a different disguise.

description: Logic gates are basic digital elements for computers. We build up thermal logic gates that can perform similar operations as their electronic counterparts. The thermal logic gates are based on the nonlinear lattices, which exhibit very intriguing phenomena due to their temperature dependent power spectra. We demonstrate that phonons, the heat carriers, can be also used to carry information and processed accordingly. The possibility of nanoscale experiment is discussed.

Infinite self-gravitating systems and cosmological structure formation

description: The usual thermodynamic limit for systems of classical self-gravitating point particles becomes well defined, as a {\it dynamical} problem, using a simple physical prescription for the calculation of the force, equivalent to the so-called ``Jeans' swindle''. The relation of the resulting intrinsically out of equilibrium problem, of particles evolving from prescribed uniform initial conditions in an infinite space, to the one studied in current cosmological models (in an expanding universe) is explained. We then describe results of a numerical study of the dynamical evolution of such a system, starting from a simple class of infinite ``shuffled lattice'' initial conditions. The clustering, which develops in time starting from scales around the grid scale, is qualitatively very similar to that seen in cosmological simulations, which begin from lattices with applied correlated displacements and incorporate an expanding spatial background. From very soon after the formation of the first non-linear structures, a spatio-temporal scaling relation describes well the evolution of the two-point correlations. At larger times the dynamics of these correlations converges to what is termed ``self-similar'' evolution in cosmology, in which the time dependence in the scaling relation is specified entirely by that of the linearized fluid theory. We show how this statistical mechanical ``toy model'' can be useful in addressing various questions about these systems which are relevant in cosmology. Some of these questions are closely analagous to those currently studied in the literature on long range interactions, notably the relation of the evolution of the particle system to that in the Vlasov limit and the nature of approximately quasi-stationary states.

description: The control of bovine tuberculosis in East Africa and. particularly in Uganda has received, very little attention although the presence of the disease was already known in the early part of the century. Literature on the history, and the present world tuberculosis situation is discussed. The epidemiology of tuberculosis and the role played by the wildlife and species other than cattle are reviewed. The literature on the incidence and prevalence of bovine tuberculosis in East Africa and Africa is reviewed with particular emphasis on bovine tuberculosis in Uganda. The literature on the control measures which have been applied to reduce the prevalence of tuberculosis infection is discussed. Discussions and recommendations are made with regard to the control of the disease, with special reference to Uganda.

description: We visualize plasma bubbles driven by 0.67 PW laser pulses in plasma of density $n_e \approx 5\times10^{17}$ ${\rm cm}^{-3}$ by imaging Faraday rotation patterns imprinted on linearly-polarized probe pulses of wavelength $λ_{pr} = 1.05 μ$m and duration $τ_{pr} = 2$ ps or $1$ ps that cross the bubble's path at right angles. When the bubble captures and accelerates tens to hundreds of pC of electron charge, we observe two parallel streaks of length $cτ_{pr}$ straddling the drive pulse propagation axis, separated by $\sim45$ $μ$m, in which probe polarization rotates by $0.3^\circ$ to more than $5^\circ$ in opposite directions. Accompanying simulations show that they result from Faraday rotation within portions of dense bubble side walls that are pervaded by the azimuthal magnetic field of accelerating electrons during the probe transit across the bubble. Analysis of the width of the streaks shows that quasi-monoenergetic high-energy electrons and trailing lower energy electrons inside the bubble contribute distinguishable portions of the observed signals, and that relativistic flow of sheath electrons suppresses Faraday rotation from the rear of the bubble. The results demonstrate favorable scaling of Faraday rotation diagnostics to $40\times$ lower plasma density than previously demonstrated.

Subjects: Linguistic Terminology

description: There is currently no bilingual Persian-English terminology for linguistics in the Persian language. The first step in compiling a bilingual Persian-English linguistic terminology is to accurately delineate the theoretical divisions of the field of linguistics. In this project, a conceptual map in Persian for the bilingual Persian-English linguistic terminology will be designed and developed, which will serve as a basis for compiling the bilingual terminology in a subsequent project.

To design a conceptual map for a scientific domain, a deductive method is typically employed, organizing various scientific fields from general to specific in a hierarchical manner. This classification depends on the subject matter expertise of linguists in different areas of linguistics and requires knowledge and experience in designing and compiling terminologies. The levels of vocabulary progression from general to specific are determined during the design process based on the resources used, and it is usually sufficient to have up to six levels of progression in the conceptual map design. Smaller domains, if they exist, can be added during the compilation of the terminology using terminology production software. Approximately 1,000 words are considered for designing the conceptual map of linguistics. Course outlines and reputable academic books at the graduate level in linguistics, as well as reference materials and specialized dictionaries in both English and Persian linguistics, will be utilized across various subfields such as Phonetics, Phonology, Morphology, Syntax, and Semantics. Additionally, historical approaches to the science of linguistics from traditional, structural, and cognitive perspectives will be taken into account. In this project, Visio software will be used for visualizing the designed maps.

description: In this scholarly work, an in-depth analysis is conducted on stabilization systems utilized in Unmanned Aerial Vehicles (UAVs) and Micro Aerial Vehicles (MAVs). The primary focus is on Inertially Stabilized Platforms (ISPs) tailored for camera payloads. The importance of this project is very high in both the defense and aerospace sectors. Key elements of stabilization systems, such as bearings, actuators, and Inertial Measurement Units (IMUs), are rigorously analyzed. Guidelines for the selection of these components are presented, emphasizing their capacity to manage both static and dynamic operational forces. The study employs specialized software tools for the evaluation and optimization of stabilization system designs. Optimization efforts are particularly directed at weight parameters, thereby enhancing system efficiency and operational performance. Acknowledgment is given to industry leaders in stabilization technologies, adding a practical dimension to the academic research. The dissertation concludes by delineating its contributions to both academic research and potential industrial applications, and suggests further research in the comparative analysis of stabilization techniques under varying operational conditions. The research serves as a critical resource for comprehending the complexities involved in the design and operation of stabilization systems in UAVs and MAVs, thereby contributing significantly to the existing literature in aerial surveillance technology.
