description: We describe and compare a Eurgnathohippus juvenile skull, RMNH67/5665 from site BKII, Olduvai Gorge, ca. 1.2 Ma. Study of the facial morphology and cheek tooth metrical data including length versus width and protocone length versus width of the dP2, 3 and 4 support the conclusion that this juvenile skull is the species Eurygnathohippus cornelianus, and that in turn Eu. cornelianus is a member of the “Sivalhippus” Complex, which includes the following superspecific clades: Sivalhippus, Eurygnathohippus, Plesiohipparion and Proboscidipparion. Recent studies suggest that Eurygnathohippus has a particularly close phylogenetic relationship with Plesiohipparion.

description: We analyze the distributions of energy, opening angle and invariant mass in muonic neutrino trident production processes, $ν_μ\to ν_μμ\overlineμ$, in a minimal gauged $U(1)_{L_μ- L_τ}$ model, in which the discrepancy of anomalous magnetic moment of muon can be solved. It is known that the total cross sections of the neutrino trident production are degenerate in new physics parameters, the new gauge coupling and gauge boson mass, and therefore other observables are needed to determine these parameters. From numerical analyses, we find that the muon energy and invariant mass distributions show the differences among the new physics parameter sets with which the total cross sections have the same value, while the anti-muon energy and opening angle distributions are not sensitive to the parameters.

description: The formation of molecular hydrogen in the interstellar medium takes place on the surfaces of dust grains. Hydrogen molecules play a role in gas-phase reactions that produce other molecules, some of which serve as coolants during gravitational collapse and star formation. Thus, the evaluation of the roduction rate of hydrogen molecules and its dependence on the physical conditions in the cloud are of great importance. Interstellar dust grains exhibit a broad size distribution in which the small grains capture most of the surface area. Recent studies have shown that the production efficiency strongly depends on the grain composition and temperature as well as on its size. In this paper we present a formula which provides the total production rate of H$_2$ per unit volume in the cloud, taking into account the grain composition and temperature as well as the grain size distribution. The formula agrees very well with the master equation results. It shows that for a physically relevant range of grain temperatures, the production rate of H$_2$ is significantly enhanced due to their broad size distribution.

description: Pampatheriidae (Middle Miocene-late Pleistocene) constitutes an extinct clade of Cingulata widely dispersed in South America, entering in Central and North America during the Great American Biotic Interchange. In the Pleistocene of South America, two genera are recorded: Pampatherium (with three species) and Holmesina (with six species). In the Pleistocene palaeofauna of Tarija Valley (Bolivia) one of the most conspicuous recorded taxa are the Cingulata, including Pampatheriidae. Until this contribution, all the remains were classified as P. typum and Pampatherium sp. Here we present a modern taxonomic revision of the Pampatheriidae of the Tarija Valley, based on previous collected and published material together with new materials obtained from fieldwork carried out during 2011-2013. The evidence indicates that a single species of Pampatheriidae is present in the Tarija Valley ( Pampatherium humboldtii ), whereas the presence of P.  typum in discarded. From a chrono-stratigraphic point of view, the biochron of this species is restricted to the late Pleistocene. This supports previous hypothesis on the age of the sediments of Tarija Valley (Tolomosa Formation).

description: Understanding the distributional impacts of market-based climate policies is crucial to design economically efficient climate change mitigation policies that are socially acceptable and avoid adverse impacts on the poor. Empirical studies that examine the distributional impacts of carbon pricing and fossil fuel subsidy reforms in different countries arrive at ambiguous results. To systematically determine the sources of variation between these outcomes, we apply an ordered probit meta-analysis framework. Based on a comprehensive, systematic and transparent screening of the literature, our sample comprises 53 empirical studies containing 183 effects in 39 countries. Results indicate a significantly increased likelihood of progressive distributional outcomes for studies on lower income countries and transport sector policies. The same applies to study designs that consider indirect effects, demand-side adjustments of consumers or lifetime income proxies.

 Like many desert countries, the UAE is rich in species of nocturnal insects that belong to the order of nerve-winged insects or Neuroptera. Members of various families that include green lacewings (Chrysopidae), brown lacewings (Hemerobiidae), antlions (Myrmeleontidae), ribbon wings (Nemopteridae) and owl flies (Ascalaphidae) are all common at suitable sites (Howarth and Gillett 2008) and can often be attracted in large numbers to light traps. More recently an insect belonging to a sixth family of this order, the Mantispidae or mantis flies, has been collected and identified. It is Mantispa nana and has been found at a number of sites, including Al Ain and Dubai and is a further new record for the UAE.

description: We present a three-dimensional (3D) extinction map of the southern sky. The map covers the SkyMapper Southern Survey (SMSS) area of $\sim$ 14,000 ${\rm deg^{2}}$ and has spatial resolutions between 6.9 and 27 arcmin. Based on the multi-band photometry of SMSS, the Two Micron All Sky Survey, the Wide-Field Infrared Survey Explorer Survey and the Gaia mission, we have estimated values of the $r$-band extinction for $\sim$ 19 million stars with the spectral energy distribution (SED) analysis. Together with the distances calculated from the Gaia data release 2 (DR2) parallaxes, we have constructed a three-dimensional extinction map of the southern sky. By combining our 3D extinction map with those from the literature, we present an all-sky 3D extinction map, and use it to explore the 3D distribution of the Galactic dust grains. We use two different models, one consisting a single disk and another of two disks, to fit the 3D distribution of the Galactic dust grains. The data is better fitted by a two-disk model, yielding smaller values of the Bayesian Information Criterion (BIC). The best fit model has scale heights of 73 and 225 pc for the "thin" and "thick" dust disks, respectively.

Исследуется поэтические особенности четырех неопубликованных стихотворных дружеских Посланий, сохранявшихся в личном архиве Терентьевой. Стихи написаны по случаю ее юбилеев. Стихотворения могут быть объединены в цикл. Их характеризует общность жанра, тематики, адресата и стилистическое единство. Проблема деструктивности времени — центральная. Автор утверждает, что в том, что «годы мчатся рысью, ходко», нет трагедии, но есть естественность процесса перехода человека в новый временной жизненный цикл, который открывает новые «величественные» возможности. В стихах создается образ адресата, обладающего чертами, которые помогают противостоять разрушительной стихии времени.

description: We consider the possibility of adding a stage to a dilution refrigerator to provide additional cooling by ``filtering out'' hot atoms. Three methods are considered: 1) Effusion, where holes having diameters larger than a mean-free path allow atoms to pass through easily; 2) Particle waveguide-like motion using very narrow channels that greatly restrict the quantum states of the atoms in a channel. 3) Wall-limited diffusion through channels, in which the wall scattering is disordered so that local density equilibrium is established in a channel. We assume that channel dimension are smaller than the mean-free path for atom-atom interactions. The particle waveguide and the wall-limited diffusion methods using channels on order of the de Broglie wavelength give cooling. Recent advances in nano-filters give this method some hope of being practical.

description: Mid-Tropospheric Cyclones (MTCs) are moist synoptic systems with distinct mid tropospheric vorticity maxima and weak signatures in the lower troposphere. Composites and statistics of MTCs over the tropics are constructed and compared with monsoon lows and depressions (together, lower troposphere cyclones; LTCs). We begin with South Asia, where tracking reveals that MTCs change character during their life, i.e., their track is composed of MTC and LTC phases. The highest MTC-phase density and least motion is over the Arabian Sea, followed by the Bay of Bengal and South China Sea. A MTC-phase composite shows an east-west tilted warm above deep cold-core temperature anomaly with maximum vorticity at 600 hPa. While the LTC-phase shows a shallow cold-core below 800 hPa and a warm upright temperature anomaly with lower tropospheric vorticity maximum. Apart from South Asia, systems with similar morphology are observed over the west and central Africa, east and west Pacific in boreal summer. In boreal winter, regions that support MTCs include northern Australia, the southern Indian Ocean, and South Africa. Relatively, the MTC fraction is higher equatorward, where there is a cross-equatorial low-level jet that advects oppositely signed vorticity. Whereas the LTCs are more prevalent further poleward. Finally, a histogram of differential vorticity (difference between middle and lower levels) versus the height of peak vorticity for cyclonic centers is bimodal. One peak, around 600 hPa, corresponds to MTCs while the second, around 900 hPa, comes from LTCs. Thus, moist cyclonic systems in the tropics have a natural tendency to reside in either the MTC or LTC category preferentially

description: We develop a microscopic theory of electron transport in superlattices within the Wannier-Stark approach by including the interaction associated with Zener tuneling among the energy levels pertaining to adjacent quantum wells. By using a Monte Carlo technique we have simulated the hopping motion associated with absorption and emission of polar optical phonons and determined the main transport parameters for the case of a GaAs/GaAlAs structure at room temperature. The interaction among the levels is found to be responsible for a systematic increase of the level energy with respect to the bottom of the quantum well at electric fields above about 20 kV/cm. When compared with the non-interacting case, at the highest fields the average carrier energy evidences a consistent increase which leads to a significant softening of the negative differential value of both the drift velocity and diffusivity.

description: Рассматриваются ахматовские образы и реминисценции в поэзии И.Бродского. На появление сходных образов повлияло тесное общение поэта с Ахматовой в начале 1960-х годов. Поэтов объединяют мотивы смерти и бессмертия, временной поэтической «смерти». Голоса прошлого и настоящего звучат в стихах «как доказательство реального существования вечности <…> в языке, литературе» (А.А.Фокин). Переход в XXI век мыслится Бродским как гарантированный для Ахматовой, но не для ее почитателей и современников. Поэт придает будущему, смерти и вечности апокалиптическую окраску, обращаясь к не характерному для Ахматовой образу коня, ищущего всадника, и к образам глаза и изумруда (зеленого цвета), соотносящимся с отмеченным в эссе о «музе плача» цветом ее глаз. У Бродского важны мотивы зрения, зеркала (из «Поэмы без героя») и стекла. Ахматовские «опыт смерти» и совмещение в фокусе призмы индивидуальной души и призмы истории «посредством просодии, которая, по сути дела, есть хранилище времени в языке». Душа и тело — распространенные мотивы у обоих поэтов. Поэту важна идея сближения земли и неба (земное — временное, небо — божественная вечность), причем сугубо приземленно звучит «солдатский шаг» (в «Реквиеме» Ахматовой — «шаги тяжелые солдат»). Молодой поэт выбирает один из главных для него этических и эстетических ориентиров.

description: Mydidae sp. (Diptera)
 The true flies belong to one of the largest insect orders, Diptera, which is subdivided into several suborders, the most substantial of which is the Brachycera or short-horned flies. This suborder contains more than 120 separate families that exhibit a wide range of behaviour and life histories. One of the smallest and least well known of these families is the Mydidae which contains about 400 species of mydas flies, including the largest of all described Diptera, Gauromydas heros (Perty 1833). The other members of the family are also relatively large insects, usually over one cm in length and many are mimics of stinging Hymenoptera (Dikow 2009). Whilst these flies are cosmopolitan in their distribution, they are more frequent in arid and semi-arid terrain, but are not often collected making them rare even in large institutional collections. The family has hitherto not been recorded from the UAE, but two unidentified species were recorded by BH within the emirates of Umm al Quwain and Dubai, with a further sighting from Dubai (Howarth 2006) (Fig. 6).

description: We propose to use a few-qubit system as a compact quantum refrigerator for cooling an interacting multi-qubit system. We specifically consider a central qubit coupled to $N$ ancilla qubits in a so-called spin-star model as our quantum refrigerator. We first show that if the interaction between the qubits is of the longitudinal and ferromagnetic Ising model form, the central qubit is colder than the environment. The colder central qubit is then proposed to be used as the refrigerant interface of the quantum refrigerator to cool down general quantum many-qubit systems. We discuss a simple refrigeration cycle, considering the operation cost and cooling efficiency, which can be controlled by $N$ and the qubit-qubit interaction strength. Besides, bounds on the achievable temperature are established. Such few-qubit compact quantum refrigerators can be significant to reduce dimensions of quantum technology applications, can be easy to integrate into all-qubit systems, and can increase the speed and power of quantum computing and thermal devices.
Identity and death : an empirical investigation
Creators: name: Lavoie, Jim A.
Publisher: name: University of British Columbia
Year: 2009

description: A model based on Erikson's psychosocial approach was proposed for the development of an existential domain of identity - conceptualized as a component of ideological identity, and operationalized as a set of death attitudes corresponding to general identity themes. Paralleling Marcia's (1966) Identity Status constructs of exploration and commitment, these death attitudes reflected death contemplation and acceptance in a variety of contexts. A sample of 149 university undergraduates completed a questionnaire consisting of a number of scales representing these death attitudes, as well as a measure of identity status. A MANCOVA (controlling for religious involvement, bereavement, and age) indicated that individuals high in ideological commitment had significantly higher levels of certain types of death acceptance, and were more likely to view death as purposeful. A MANCOVA examining the effects of ideological exploration on variables associated with death contemplation was also conducted, but the multivariate effect was not significant. An exploratory ideological identity status MANCOVA indicated, however, that achievers may have a significantly more personal conception of death than diffusions. These results suggest that amongst young adult students, death ideology is relevant at least as a socially constructed (or foreclosed) form of identity.

Spectral properties and enhanced superconductivity in renormalized Migdal-Eliashberg theory

description: Migdal-Eliashberg theory describes the properties of the normal and superconducting states of electron-phonon mediated superconductors based on a perturbative treatment of the electron-phonon interactions. It is necessary to include both electron and phonon self-energies self-consistently in Migdal-Eliashberg theory in order to match numerically exact results from determinantal quantum Monte Carlo in the adiabatic limit. In this work we provide a method to obtain the real-axis solutions of the Migdal-Eliashberg equations with electron and phonon self-energies calculated self-consistently. Our method avoids the typical challenge of computing cumbersome singular integrals on the real axis and is numerically stable and exhibits fast convergence. Analyzing the resulting real-frequency spectra and self-energies of the two-dimensional Holstein model, we find that self-consistently including the lowest-order correction to the phonon self-energy significantly affects the solution of the Migdal-Eliashberg equations. The calculation captures the broadness of the spectral function, renormalization of the phonon dispersion, enhanced effective electron-phonon coupling strength, minimal increase in the electron effective mass, and the enhancement of superconductivity which manifests as a superconducting ground state despite strong competition with charge-density-wave order. We discuss surprising differences in two common definitions of the electron-phonon coupling strength derived from the electron mass and the density of states, quantities which are accessible through experiments such as angle-resolved photoemission spectroscopy and electron tunneling. An approximate upper bound on $2Δ/ T_c$ for conventional superconductors mediated by retarded electron-phonon interactions is proposed.

description: We show that there exists a universal quantum Turing machine (UQTM) that can simulate every other QTM until the other QTM has halted and then halt itself with probability one. This extends work by Bernstein and Vazirani who have shown that there is a UQTM that can simulate every other QTM for an arbitrary, but preassigned number of time steps. As a corollary to this result, we give a rigorous proof that quantum Kolmogorov complexity as defined by Berthiaume et al. is invariant, i.e. depends on the choice of the UQTM only up to an additive constant. Our proof is based on a new mathematical framework for QTMs, including a thorough analysis of their halting behaviour. We introduce the notion of mutually orthogonal halting spaces and show that the information encoded in an input qubit string can always be effectively decomposed into a classical and a quantum part.

title: Precision measurement and the genesis of physics teaching laboratories in Victorian Britain
Creators: name: Gooday, G. J. N
Publisher: name: University of Kent
Year: 2021

description: This thesis examines the ascendance of Victorian acidnic physics laboratories as institutions primarily devoted the undergraduate instruction in the techniques of precision measurement. The genesis of these teaching laboratories in established centres of higher education is shown to be specific to the period 1866-1874. This temporal specificityis analysed in terms of the confluence of an industrially-generated "demand" for practical scientific education and an independent research generated "supply" of academic expertise in precision measurement. Case stixiles assess the variation of pedagogical practices according to local institutional factors and the biographical characteristics of incumbent professors of experimental physics in seven English and Scottish laboratories • Three sub-groups of British nRd'ini c physicists are thereby identified: i) non-analytical experimentalists in London and Oxfords who supplied comprehensive and regimented courses of training in the techniques of exact measurement; ii) Scottish natural philosophers in Glasgow, Edinburgh and Manchester who characteristically enlisted undergraduate assistance in professorial measurement researches; and iii) Cambridge analysts who allowed at most only an elite of the indigenous mathematics graduates to pursue independent investigations in their laboratories. The tensions between traditions i) and iii) are illustrated in the divergence of the Cambridge analyst James Clerk Maxwell from the pedagogical interests and practices of the majority of academic laboratory physicists as represented by the Physical Society founded in 1873-74. Maxwell's dissidence is demonstrated in a brief account of his management of the Cavendish Laboratory as a generically unique centre of postgraduate research from 1874-79. Nevertheless, it is shown that laboratory precision measurement, as the universally recognized vehicle for progress in physics between the 1860's and 1890's, was practised in common by Maxwell and the distinct community of academic experimentalists which existed "before and beyond" the Cavendish Laboratory

The problem is mapped into the exactly solvable Surm-Liouville problem with the Rosen-Morse potential and exact bounded solutions for particles and antiparticles are found. The behaviour of the spectrum is discussed in some detail. An apparent paradox concerning the uncertainty principle is solved by recurring to the concept of effective Compton wavelength.

description: Omanaster imbricatus is a new genu s and species of Sakmarian (Early Permian) asteroids collected from the basal Pachycyrtella Bed of the Saiwan Formation of Oman, Arabian Peninsula; the family Omanasteridae is recognized. Late Paleozoic and especially Permian asteroids are rare and O. imbricatus differs significantly from those previously described, thereby providing an important addition to known late Paleozoic diversity. Unfortunately the single available specimen is incomplete with remaining ossicles both leached and partially fused, and available data are limited. Adambulacral form and arrangement of O. imbricatus are both suggestive of corresponding expressions of certain earlier Paleozoic species and unlike those of the crown-group, suggesting an enduring Paleozoic lineage but one not phylogenetically a part of the Mesozoic diversification. The Pachycyrtella Bed has been interpreted as recording a succession of pioneer palaeocommunities colonizing a turbulent, shallow-water settingaffected by oscillatory flows. The apparently flattened appearance of O. imbricatus is suggestive of appearances of certain Cretaceous and extant species recovered from similar environments thus suggesting both homoplasy and the versatility of asteroid evolution across extended spans of geologic time.

description: Deep learning algorithms have seen acute growth of interest in their applications throughout several fields of interest in the last decade, with medical hyperspectral imaging being a particularly promising domain. So far, to the best of our knowledge, there is no review paper that discusses the implementation of deep learning for medical hyperspectral imaging, which is what this review paper aims to accomplish by examining publications that currently utilize deep learning to perform effective analysis of medical hyperspectral imagery. This paper discusses deep learning concepts that are relevant and applicable to medical hyperspectral imaging analysis, several of which have been implemented since the boom in deep learning. This will comprise of reviewing the use of deep learning for classification, segmentation, and detection in order to investigate the analysis of medical hyperspectral imaging. Lastly, we discuss the current and future challenges pertaining to this discipline and the possible efforts to overcome such trials.

description: We present a detailed mid-infrared study of the nearby, face-on spiral galaxy M83 based on ISOCAM data. M83 is a unique case study, since a wide variety of MIR broad-band filters as well as spectra, covering the wavelength range of 4 to 18μm, were observed and are presented here. Emission maxima trace the nuclear and bulge area, star-formation regions at the end of the bar, as well as the inner spiral arms. The fainter outer spiral arms and interarm regions are also evident in the MIR map. Spectral imaging of the central 3'x3' (4 kpc x 4 kpc) field allows us to investigate five regions of different environments. The various MIR components (very small grains, polycyclic aromatic hydrocarbon (PAH) molecules, ionic lines) are analyzed for different regions throughout the galaxy. In the total 4μm to 18μm wavelength range, the PAHs dominate the luminosity, contributing between 60% in the nuclear and bulge regions and 90% in the less active, interarm regions. Throughout the galaxy, the underlying continuum emission from the small grains is always a smaller contribution in the total MIR wavelength regime, peaking in the nuclear and bulge components. The implications of using broad-band filters only to characterize the mid-infrared emission of galaxies, a commonly used ISOCAM observation mode, are discussed. We present the first quantitative analysis of new H-alpha and 6cm VLA+Effelsberg radio continuum maps of M83. The distribution of the MIR emission is compared with that of the CO, HI, R band, H-alpha and 6cm radio. A striking correlation is found between the intensities in the two mid-infrared filter bands and the 6cm radio continuum. To explain the tight mid-infrared-radio correlation we propose the anchoring of magnetic field lines in the photoionized shells of gas clouds.

description: Fossil evidence of late Palaeozoic ginkgophytes is rare; Palaeozoic floras in which ginkgophytes are abundant or represent a predominant element have not previously been described. The late Permian (Lopingian) flora from the Gröden/Val Gardena Sandstone of the Bletterbach gorge in the Dolomites (northern Italy) contains an unusually large proportion of ginkgophytes. The fossils include the foliage taxa Baiera digitata and Sphenobaiera sp., as well as putative O-ha-tsuki -type fertile leaves, seeds, and several ginkgophyte-like leaf types of uncertain affinities. Local mass occurrences of ginkgophyte leaves have also been observed.The Bletterbach flora suggests that ginkgophytes were important elements in certain vegetation types (probably forests) as early as the late Permian.

Colour dipoles and the HERA data

description: A very wide body of HERA diffractive electroproduction data is confronted with the predictions of the colour dipole model. In doing so we focus upon three different parameterisations of the dipole scattering cross-section, whose parameters are fixed by analysis of DIS structure function data. This analysis strongly suggests the presence of saturation effects, but is not definitive because the conclusion requires the inclusion of data at low-$Q^2$ values. Having fixed the parameters of the models from the DIS structure function data, the resulting dipole cross sections can be used to make genuine predictions for other reactions. Good agreement is obtained for all observables, as is illustrated here for deeply virtual Compton scattering(DVCS) and diffractive deep inelastic scattering(DDIS). There can be no doubting the success of the dipole scattering approach and more precise observations are needed in order to expose its limitations

Bump hunting in regression revisited

Publisher: name: University of British Columbia

description: Suppose bivariate data [formula] are observed at times a ≤ t1 ≤ t2 ≤ ... ≤ tn ≤ b. Given a nonparametric regression model [formula] mean 0, variance ϭ² , for i = 1, 2 , . . . , n, we want to estimate the number of modes of the underlying regression function m(-) or its derivative. We use the penalized least squares technique to get an estimate of m(-), i.e. the function minimizing [formula] where [formula] dt is a penalty function and ƛ is a smoothing parameter. The estimate of the derivative, m’ is simply the derivative of the estimate, (m’). A new test of multimodality is introduced and its performance is studied. Our idea is motivated by the test proposed by Silverman (1981) concerning the number of modes in the density function. He used a "critical bandwidth" as a test statistic in a kernel smoothing context. He noted that if the data are strongly bimodal, we would need a large value of a bandwidth to obtain a unimodal density estimate. In our case we define the "critical smoothing parameter" Xcrit as the smallest ƛ giving an estimate with the specified number of modes. We use Ac r ; 4 as a test statistic in our new test CriSP. We use bootstrap techniques to assess the performance of our test. We study the effects of the penalty L on the quality of our test via simulation using different regression functions and we compare it with Bowman et.al.'s monotonicity test (1998). CriSP is also applied to the children's growth data in studying the number of bumps in the derivatives of the growth functions. In a sample of 43 boys and 50 girls, our test procedure gives an automatic classification rule in about 80% of the growth curves analyzed.

description: A new Middle Triassic (Uppermost Anisian, Illyrian) gastropod genus and species, Rasatomaria gentilii gen. n. sp. n. , is described from the San Salvatore Formation from Rasa, an outer district of the town Varese (Lombardy, Italy). The studied specimens come from a diverse benthic marine assemblage, which is dominated by gastropods and bivalves. Based on ammonoids, this assemblage belongs to the Nevadites secedensis Zone. The new gastropod taxon is very low-spired, widely phaneromphalous, has a selenizone slightly above the periphery of the whorls and a dominant spiral ornament. It belongs to the superfamily Pleurotomarioidea and its knowledge improves our understanding of the Middle and Late Triassic radiation of this group.

description: We present the experimental status of electromagnetic hadron form factors. New and surprising results, based on polarization measurements, have been recently obtained for the electric proton and neutron form factors. In particular, the electric and magnetic distributions inside the proton appear not to be the same, in disagreement with results extracted from the unpolarized cross section, using the Rosenbluth separation. The new findings have given rise to a large number of papers and different speculations, as they question directly the models of nucleon structure and the reaction mechanism itself (based on $1γ$-exchange), with a possible revision of the calculation of radiative corrections, two-photon contribution etc. New data in time-like region are also available, through annihilation reactions. A large interest in this field arises, due also to the possibility of new measurements in polarized electron nucleon elastic scattering at JLab, and also in the time-like region, at Frascati and at the future FAIR international facility.

description: We have discovered a new candidate redback millisecond pulsar binary near the center of the error ellipse of the bright unassociated Fermi-LAT $γ$-ray source 4FGL J0940.3-7610. The candidate counterpart is a variable optical source that also shows faint X-ray emission. Optical photometric and spectroscopic monitoring with the SOAR telescope indicates the companion is a low-mass star in a 6.5-hr orbit around an invisible primary, showing both ellipsoidal variations and irradiation and consistent with the properties of known redback millisecond pulsar binaries. Given the orbital parameters, preliminary modeling of the optical light curves suggests an edge-on inclination and a low-mass ($\sim 1.2$ - $1.4\,M_{\odot}$) neutron star, along with a secondary mass somewhat more massive than typical $\gtrsim 0.4\,M_{\odot}$. This combination of inclination and secondary properties could make radio eclipses more likely for this system, explaining its previous non-discovery in radio pulsation searches. Hence 4FGL J0940.3-7610 may be a strong candidate for a focused search for $γ$-ray pulsations to enable the future detection of a millisecond pulsar.

description: Представлен сопоставительный анализ двух пропагандистских артефактов периода советско-финской войны 1939—1940 гг. Советская маршевая песня эксплуатирует возможности «большого стиля» в искусстве, где доминирует монументальность, пафос и актуальная для рецепции потенциальной аудитории мифологическая структура. Истинное назначение и цели войны деформируются созданием ложного по смыслу нарратива. Финский музыкальный памфлет по формальным признакам строится на другой основе. Включенные в текст ирония и сатира на первый взгляд воспринимаются как справедливая оценка действий агрессора. Вместе с тем, композитор и автор текста апеллируют, в первую очередь, к эмоциональному аспекту восприятия и по-своему деформируют реальность. В памфлете актуализируются идеи национальной непримиримости, абсолютно негативной интерпретации общей истории существования государств и демонизация противника. В конечном итоге оба текста в равной степени используют технику манипуляции массовым сознанием, опираясь при этом на особенности менталитета и политической культуры своей аудитории.

description: We present preliminary results of 3-D hydro simulations of the interstellar medium evolution in dwarf spheroidal galaxies undergoing star formation for the first time. The star formation is assumed to occur in a sequence of instantaneus bursts separated by quiescent periods. Different models are made changing the number and the intensity of the bursts in such a way that the final mass of the formed stars remains the same. We followed the enrichment of the ISM taking into account the contribution of both type Ia and II supernovae. The aim of our models is to find a star formation history compatible with the observed spread of stellar age and metallicity in such galaxies and to reproduce the observed mass-metallicity relation.
