description: We consider a scenario where dark matter (DM) interacts exclusively with Standard Model (SM) leptons at tree level. Due to the absence of tree-level couplings to quarks, the constraints on leptophilic dark matter arising from direct detection and hadron collider experiments are weaker than those for a generic WIMP. We study a simple model in which interactions of DM with SM leptons are mediated by a leptophilic $Z'$ boson, and determine constraints on this scenario arising from relic density, direct detection, and other experiments. We then determine current LHC limits and project the future discovery reach. We show that, despite the absence of direct interactions with quarks, this scenario can be strongly constrained.

description: Decagonal quasiperiodic ordering of Sn thin film on $d$-Al-Ni-Co, is shown based on scanning tunneling microscopy (STM), low-energy electron diffraction and density functional theory (DFT). Interestingly, the decagonal structural correlations are partially retained up to a large film thickness of 10 nm grown at a 165$\pm$10 K. The nucleation centers called 'Sn white flowers' identified by STM at submonolayer thickness are recognized as valid patches of the decagonal clathrate structure with low adsorption energies. Due to the excellent lattice matching (to within 1%) between columns of Sn dodecahedra in the clathrate structure and pentagonal motifs at the $d$-Al-Ni-Co surface, the interfacial energy favors clathrate over the competing Sn crystalline forms. DFT study of the Sn/Al-Ni-Co composite model shows good mechanical stability, as shown by the work of separation of Sn from Al-Ni-Co slab that is comparable to clathrate self-separation energy. The relaxed surface terminations of the R$_2$T$_4$ clathrate approximant are in self-similarity correspondence with the motifs observed in the STM images from monolayer to thickest Sn film.

Positive-incentive Noise

description: Noise is conventionally viewed as a severe problem in diverse fields, e.g., engineering, learning systems. However, this paper aims to investigate whether the conventional proposition always holds. It begins with the definition of task entropy, which extends from the information entropy and measures the complexity of the task. After introducing the task entropy, the noise can be classified into two kinds, Positive-incentive noise (Pi-noise or $π$-noise) and pure noise, according to whether the noise can reduce the complexity of the task. Interestingly, as shown theoretically and empirically, even the simple random noise can be the $π$-noise that simplifies the task. $π$-noise offers new explanations for some models and provides a new principle for some fields, such as multi-task learning, adversarial training, etc. Moreover, it reminds us to rethink the investigation of noises.

description: The essential singularity in Einstein's gravity can be avoidable if the preconditions of Penrose's theorem can be bypassed, i.e., if the strong energy condition is broken in the vicinity of a black hole center. The singularity mentioned here includes two aspects: (i) the divergence of curvature invariants, and (ii) the incompleteness of geodesics. Both aspects are now taken into account in order to determine whether a black hole contains essential singularities. In this sense, black holes without essential singularities are dubbed regular (non-singular) black holes. The regular black holes have some intriguing phenomena that are different from those of singular black holes, and such phenomena have inspired numerous studies. In this review, we summarize the current topics that are associated with regular black holes.

description: Exceptional points (EPs) of non-Hermitian (NH) systems have recently attracted increasing attention due to their rich phenomenology and intriguing applications. Compared to the predominantly studied second-order EPs, higher-order EPs have been assumed to play a much less prominent role because they generically require the tuning of more parameters. Here we experimentally simulate two-dimensional topological NH band structures using single-photon interferometry, and observe topologically stable third-order EPs obtained by tuning only two real parameters in the presence of symmetry. In particular, we explore how different symmetries stabilize qualitatively different third-order EPs: the parity-time symmetry leads to a generic cube-root dispersion, while a generalized chiral symmetry implies a square-root dispersion coexisting with a flat band. Additionally, we simulate fourfold degeneracies, composed of the non-defective twofold degeneracies and second-order EPs. Our work reveals the abundant and conceptually richer higher-order EPs protected by symmetries and offers a versatile platform for further research on topological NH systems.

description: The inheritance of material across the star and planet formation process is traced by deuterium fractionation. We report here the first detection of doubly deuterated methanol towards pre-stellar cores. We study the deuterium fractionation of methanol, CH$_{3}$OH, towards two starless and two pre-stellar cores. We derive a D/H ratio of 0.8-1.9$\%$ with CH$_{2}$DOH in pre-stellar cores H-MM1 and L694-2, consistent with measurements in more evolved Class 0/I objects and comet 67P/Churyumov-Gerasimenko, suggesting a direct chemical link arising in the pre-stellar stage. Furthermore, the column density ratios of CHD$_{2}$OH/CH$_{2}$DOH are $\sim$50-80$\%$, consistently high as that towards Class 0/I objects, indicating an efficient formation mechanism of CHD$_{2}$OH, possibly through H atom additions to D$_{2}$CO. The CH$_{2}$DOH/CH$_{3}$OH and CHD$_{2}$OH/CH$_{3}$OH column density ratios in the two pre-stellar cores are larger than that in the two starless cores B68 and L1521E, representing an evolutionary trend of methanol deuteration in early-stage cores.

description: [Context]. The standard solar model fails to predict the very low lithium abundance in the Sun, which is much lower than the proto-solar nebula. This Li problem has been debated for decades, and it has been ascribed either to planet formation or to secular stellar depletion. In order to test the evolution of Li, it is important to find solar twins in a range of ages. Also, the study of stars similar to the Sun is relevant in relation to the signature of terrestrial planet formation around the Sun. [Methods]. We acquired high-resolution (R=110,000), high S/N (~300) ESO/VLT UVES spectra of several solar twin candidates and the Sun (as reflected from the asteroid Juno). Among the solar twin candidates we identify HIP 114328 as a solar twin and perform a differential line-by-line abundance analysis of this star relative to the Sun. [Results]. HIP 114328 has stellar parameters Teff = 5785+/-10 K, log g = 4.38+/-0.03, [Fe/H] = -0.022+/-0.009, and a microturbulent velocity 0.05+/-0.03 km/s higher than solar. The differential analysis shows that this star is chemically very similar to the Sun. The refractory elements seem even slightly more depleted than in the Sun, meaning that HIP 114328 may be as likely to form terrestrial planets as the Sun. HIP 114328 is about 2 Gyr older than the Sun, and is thus the second oldest solar twin analyzed at high precision. It has a Li abundance of A(Li)NLTE <= 0.46, which is about 4 times lower than in the Sun (A(Li)NLTE = 1.07 dex), but close to the oldest solar twin known, HIP 102152. [Conclusions]. Based on the lower abundances of refractory elements when compared to other solar twins, HIP 114328 seems an excellent candidate to host rocky planets. The low Li abundance of this star is consistent with its old age and fits very well the emerging Li-age relation among solar twins of different ages.

description: The UV spectral range (1100 - 3000 A) contains the strongest resonance lines observed in active galactic nuclei (AGN). Analysis of UV line intensity ratios and profile shapes in quasar spectra provide diagnostics of physical and dynamical conditions in the broad line emitting region. This paper discusses properties of UV lines in type-1 AGN spectra, and how they lead an estimate of ionizing photon flux, chemical abundances, radius of the broad line emitting region and central black hole mass. These estimates are meaningfully contextualised through the 4D "eigenvector-1" (4DE1) formalism.

description: В статье исследуются «Философия общего дела» Н. Федорова и философские взгляды писателя А. Платонова на эту проблему. Ставится вопрос о цели этой долгой и сложной работы и о тех, кто сможет ее завершить. Н. Федоров считает, что необходимо восстановить культ предков, вернуть сердца сыновей их отцам, и воскресение всех отцов станет высшим проявлением единства всех сыновей с отцами. Воскрешение отцов считается важнейшей целью всех людей на Земле, которые будут населять Вселенную после воскрешения всех предков. По словам А. Платонова, дети – строители и жители будущего, они главные люди, которые станут настоящими хозяевами. Чтобы стать мастером, нужно пройти долгий и мучительный путь через страдания и смерти близких людей. Политическое название нового мира – коммунизм, а начало пути к нему – революция. Чтобы создать новый мир, все люди должны объединиться для одной совместной деятельности – построить город для всех.

description: We study the critical spin-polarization energy ($α_{\rm C}$) above which fractional quantum Hall states in two-dimensional electron systems confined to symmetric GaAs quantum wells become fully spin-polarized. We find a significant decrease of $α_{\rm C}$ as we increase the well-width. In systems with comparable electron layer thickness, $α_{\rm C}$ for fractional states near Landau level filling $ν=3/2$ is about twice larger than those near $ν=1/2$, suggesting a broken particle-hole symmetry. Theoretical calculations, which incorporate Landau level mixing through an effective three-body interaction, and finite layer thickness, capture certain qualitative features of the experimental results.
title: Evolution of inner ear shape in Afrotheria
Creators: name: Hollinetz, Fabian
Year: 2023

description: Das Innenohr der Säugetiere hat trotz theoretischer Beschränkungen seiner Evolvabilität, insbesondere einer engen räumlichen Integration mit vielen funktionell unterschiedlichen Komponenten in unmittelbarer Nähe zueinander und einer kurzen Entwicklungszeit, Anpassungen an verschiedene Umweltbedingungen und zahlreiche evolutionäre Neuheiten erfahren. Dies sollte zu geringeren Anzeichen konvergenter Evolution und einer stärkeren Abhängigkeit der Form von der Phylogenie führen. Zur Verifizierung dieser Vorhersagen, verwendete ich Methoden der geometrischen Morphometrie, um die Form des Innenohrs der Säugetiere von 20 Arten Afrotheria mit den Formen von 20 ökologisch ähnlichen, aber nur entfernt verwandten Säugetierarten zu vergleichen. Die Formen wurden mittels Principal Component Analysis verglichen, die zeigte, dass die Innenohrformen der Afrotheria eher denen ihrer Analoga ähnelten als jenen anderer Afrotheria. Partial Least Squares Analysis wurde verwendet, um Zusammenhänge zwischen der Form des Innenohrs und ökologischen, lokomotorischen und Haltungsvariablen zu finden. Sie kontrastierte hauptsächlich aquatische mit nicht-aquatischen Arten in der ersten Komponente und arboreale gegenüber fossorialen Arten in der zweiten Komponente. Daraus ergab sich die Schlussfolgerung, dass die Ökologie, im Gegensatz zu phylogenetischen Beziehungen, der vorherrschende Einflussfaktor auf die Form des Innenohrs ist.
description: The mammalian inner ear has seen adaptations to various environmental regimes and multiple evolutionary novelties despite theoretical constraints to its evolvability, mainly tight spatial integration with lots of functionally different components in close proximity and a short developmental timespan. This should lead to less signs of convergent evolution and a greater dependence of shape on phylogeny. In order to test such predictions, I used methods from geometric morphometrics to compare the inner ear shape of 20 afrotherian species to the shapes of 20 ecologically similar, but only distantly related mammalian species. Shapes were compared via principal component analysis, which showed afrotherian inner ear shapes to be more similar to those of their analogues than to other afrotherian species. Partial least squares analysis was used to find associations between inner ear shape and ecological, locomotor and postural variables. It mainly contrasted aquatic with non-aquatic species in the first component and arboreal versus fossorial species in the second. This led to the conclusion that ecology is the predominant influencing factor for inner ear shape as opposed to phylogenetic relationships.

Following the recent experimental observation of vortices in Bose-Einstein condensates comprised of atoms with inherent long-range dipole-dipole interactions [Nat. Phys. 18, 1453-1458 (2022)], we thoroughly investigate vortex properties in the three-dimensional dominantly dipolar regime, where beyond-mean-field effects are crucial for stability, and investigate the interplay between trap geometry and magnetic field tilt angle.

description: Настоящая статья посвящена изучению одной из проблем поэзии известного дагестанского поэта, переводчика, публициста и писателя М. Ахмедова. Поэтическое творчество М. Ахмедова – яркая, но неизученная страница современной аварской и в целом дагестанской литературы. Поэтическая концепция пространства и времени в поэзии М. Ахмедова – это не только не исследованный пласт философской лирики М. Ахмедова, но и интересное явление в процессе развития современной аварской и дагестанской литературы. В связи с тем, что в статье мы подвергаем анализу философские проблемы, которые до настоящего времени не становились объектом научного интереса дагестанских литературоведов, в процессе работы мы опирались на труды русских ученых: Д.С. Лихачева, М.М. Бахтина, Ю.М. Лотмана и др. В статье впервые вводятся в научный оборот произведения, в которых автор поднимает проблемы пространственно-временных закономерностей, при этом особое внимание акцентируется на их художественном своеобразии. В центре внимания – философская проблематичность художественных исканий М. Ахмедова, отношение автора к философскому пониманию бытия, жизни, человека, человечности и природы. Мотивы художественного мышления поэта, тесно связанные с категориями времени и пространства, в статье раскрываются через анализ и осмысление поэтического языка автора, подчеркивая меткость и выразительность языковых форм и конструкций. Литературоведческий анализ философских произведений М. Ахмедова, предпринятый с целью выявить некоторые особенности поэтики, композиционного строя, образной системы, базируется на лучших образцах философской лирики поэта, в которых красной нитью проходят пространственно-временные категории, что позволяет проследить процесс развития национальных художественных традиций в поэтическом творчестве М. Ахмедова и опыт преемственности в аварской литературе.
How ψ-epistemic models fail at explaining the indistinguishability of quantum states

description: We study the extent to which ψ-epistemic models for quantum measurement statistics---models where the quantum state does not have a real, ontic status---can explain the indistinguishability of nonorthogonal quantum states. This is done by comparing the overlap of any two quantum states with the overlap of the corresponding classical probability distributions over ontic states in a ψ-epistemic model. It is shown that in Hilbert spaces of dimension $d \geq 4$, the ratio between the classical and quantum overlaps in any ψ-epistemic model must be arbitrarily small for certain nonorthogonal states, suggesting that such models are arbitrarily bad at explaining the indistinguishability of quantum states. For dimensions $d$ = 3 and 4, we construct explicit states and measurements that can be used experimentally to put stringent bounds on the ratio of classical-to-quantum overlaps in ψ-epistemic models, allowing one in particular to rule out maximally ψ-epistemic models more efficiently than previously proposed.

Inclusive and differential cross-sections for dilepton $t\bar{t}$ production measured in $\sqrt{s}=13\;$TeV $pp$ collisions with the ATLAS detector

description: Differential and double-differential distributions of kinematic variables of leptons from decays of top-quark pairs ($t\bar{t}$) are measured using the full LHC Run 2 data sample collected with the ATLAS detector. The data were collected at a $pp$ collision energy of $\sqrt{s}=13$ TeV and correspond to an integrated luminosity of 140 fb$^{-1}$. The measurements use events containing an oppositely charged $eμ$ pair and $b$-tagged jets. The results are compared with predictions from several Monte Carlo generators. While no prediction is found to be consistent with all distributions, a better agreement with measurements of the lepton $p_{\text{T}}$ distributions is obtained by reweighting the $t\bar{t}$ sample so as to reproduce the top-quark $p_{\text{T}}$ distribution from an NNLO calculation. The inclusive top-quark pair production cross-section is measured as well, both in a fiducial region and in the full phase-space. The total inclusive cross-section is found to be \[ σ_{t\bar{t}} = 829 \pm 1\;(\textrm{stat}) \pm 13\;(\textrm{syst}) \pm 8\;(\textrm{lumi}) \pm 2\; (\textrm{beam})\ \textrm{pb}, \] where the uncertainties are due to statistics, systematic effects, the integrated luminosity and the beam energy. This is in excellent agreement with the theoretical expectation.

description: Periodically driven quantum dots can act as counterparts of cyclic thermal machines at the nanoscale. In the slow-driving regime of geometric pumping, such machines have been shown to operate in analogy to a Carnot cycle. For larger driving frequencies, which are required in order to increase the cooling power, the efficiency of the operation decreases. Up to which frequency a close-to-optimal performance is still possible depends on the magnitude and sign of on-site electron-electron interaction. Extending our previous detailed study on cyclic quantum-dot refrigerators [Phys. Rev. B 106, 035405 (2022)], we here find that the optimal cooling power remains constant up to weak interaction strength compared to the cold-bath temperature. By contrast, the work cost depends on the interaction via the dot's charge relaxation rate, as the latter sets the typical driving frequency for the onset of non-geometric pumping contributions.

description: The ESA Gaia space astrometry mission will perform an all-sky survey of stellar objects complete in the nominal magnitude range G = [6.0 - 20.0]. The stars with G lower than 6.0, i.e. those visible to the unaided human eye, would thus not be observed by Gaia. We present an algorithm configuration for the Gaia on-board autonomous object observation system that makes it possible to observe very bright stars with G = [2.0-6.0). Its performance has been tested during the in-orbit commissioning phase achieving an observation completeness of ~94% at G = 3 - 5.7 and ~75% at G = 2 - 3. Furthermore, two targeted observation techniques for data acquisition of stars brighter than G = 2.0 were tested. The capabilities of these two techniques and the results of the in-flight tests are presented. Although the astrometric performance for stars with G lower than 6.0 has yet to be established, it is clear that several science cases will benefit from the results of the work presented here.

Автор дает краткий обзор рецепции романа, отдельно останавливаясь на сложившейся в критике в связи с этим романом концепции «писательской неудачи». Данная статья посвящена разбору одного из ключевых мотивов у Мелвилла – проблеме осмысления понятия «оригинального», что позволяет очертить поле необходимых дальнейших русскоязычных исследований поэтики и проблематики данного произведения, до сих пор отсутствовавших в отечественном литературоведении. Целью статьи является анализ образа Художника, мотива творения мистической книги, выделяются и описываются характерные особенности мелвилловской философии творчества, нашедшей отражение в художественном мире его произведений 1850-х годов. Проведенный анализ позволяет говорить о романе как об автометатексте, а также отметить его жанровые особенности в рамках традиции романа о художнике.

description: Purpose: Target delineation for radiation therapy is a time-consuming and complex task. Autocontouring gross tumor volumes (GTVs) has been shown to increase efficiency. However, there is limited literature on post-operative target delineation, particularly for CT-based studies. To this end, we trained a CT-based autocontouring model to contour the post-operative GTV of pediatric patients with medulloblastoma. Methods: 104 retrospective pediatric CT scans were used to train a GTV auto-contouring model. 80 patients were then preselected for contour visibility, continuity, and location to train an additional model. Each GTV was manually annotated with a visibility score based on the number of slices with a visible GTV (1 = <25%, 2 = 25%-50%, 3 = >50%-75%, and 4 = >75%-100%). Contrast and the contrast-to-noise ratio (CNR) were calculated for the GTV contour with respect to a cropped background image. Both models were tested on the original and pre-selected testing sets. The resulting surface and overlap metrics were calculated comparing the clinical and autocontoured GTVs and the corresponding clinical target volumes (CTVs). Results: 80 patients were pre-selected to have a continuous GTV within the posterior fossa. Of these, 7, 41, 21, and 11 were visibly scored as 4, 3, 2, and 1, respectively. The contrast and CNR removed an additional 11 and 20 patients from the dataset, respectively. The Dice similarity coefficients (DSC) were 0.61 +/- 0.29 and 0.67 +/- 0.22 on the models without pre-selected training data and 0.55 +/- 13.01 and 0.83 +/- 0.17 on the models with pre-selected data, respectively. The DSC on the CTV expansions were 0.90 +/- 0.13. Conclusion: We automatically contoured continuous GTVs within the posterior fossa on scans that had contrast >=10 HU. CT-Based auto-contouring algorithms have potential to positively impact centers with limited MRI access.

description: In this paper consensus in second-order multi-agent systems with a non-periodic sampled-data exchange among agents is investigated. The sampling is random with bounded inter-sampling intervals. It is assumed that each agent has exact knowledge of its own state at all times. The considered local interaction rule is PD-type. The characterization of the convergence properties exploits a Lyapunov-Krasovskii functional method, sufficient conditions for stability of the consensus protocol to a time-invariant value are derived. Numerical simulations are presented to corroborate the theoretical results.

description: Metal tubes plated with nickel-phosphorus are used in many fundamental physics experiments using ultracold neutrons (UCN) because of their ease of fabrication. These tubes are usually polished to a average roughness of 25-150 nm. However, there is no scattering model that accurately describes UCN scattering on such a rough guide surface with a mean-square roughness larger than 5 nm. We therefore developed a scattering model for UCN in which scattering from random surface waviness with a size larger than the UCN wavelength is described by a microfacet Bidirectional Reflectance Distribution Function model (mf-BRDF model), and scattering from smaller structures by the Lambert's cosine law (Lambert model). For the surface waviness, we used the statistical distribution of surface slope measured by an atomic force microscope on a sample piece of guide tube as input of the model. This model was used to describe UCN transmission experiments conducted at the pulsed UCN source at J-PARC. In these experiments, a UCN beam collimated to a divergence angle smaller than $\pm 6^{\circ}$ was directed into a guide tube with a mean-square roughness of 6.4 nm to 17 nm at an oblique angle, and the UCN transport performance and its time-of-flight distribution were measured while changing the angle of incidence. The mf-BRDF model combined with the Lambert model with scattering probability $p_{L} = 0.039\pm0.003$ reproduced the experimental results well. We have thus established a procedure to evaluate the characteristics of UCN guide tubes with a surface roughness of approximately 10 nm.

description: We study the colour and star formation rates of paired galaxies in filaments and sheets using the EAGLE simulations. We find that the major pairs with pair separation $<50$ kpc are bluer and more star forming in filamentary environments compared to those hosted in sheet-like environments. This trend reverses beyond a pair separation of $\sim 50$ kpc. The interacting pairs with larger separations ($>50$ kpc) in filaments are on average redder and low-star forming compared to those embedded in sheets. The galaxies in filaments and sheets may have different stellar mass and cold gas mass distributions. Using a KS test, we find that for paired galaxies with pair separation $<50$ kpc, there are no significant differences in these properties in sheets and filaments. The filaments transport gas towards the cluster of galaxies. Some earlier studies find preferential alignment of galaxy pairs with filament axis. Such alignment of galaxy pairs may lead to different gas accretion efficiency in galaxies residing in filaments and sheets. We propose that the enhancement of star formation rate at smaller pair separation in filaments is caused by the alignment of galaxy pairs. A recent study with the SDSS data (Das et al., 2023) reports the same findings. The confirmation of these results by the EAGLE simulations suggests that the hydrodynamical simulations are powerful theoretical tools for studying the galaxy formation and evolution in the cosmic web.

description: Nearly all intragroup (IGL) and intracluster light (ICL) comes from stars that are not bound to any single galaxy but were formed in galaxies and later unbound from them. In this review we focus on the physical properties - phase space properties, metallicity and age distribution - of the ICL and IGL components of the groups and clusters in the local universe, within 100 Mpc distance. Kinematic information on these very low surface brightness structures mostly comes from discrete tracers such as planetary nebulae and globular clusters, showing highly unrelaxed velocity distributions. Cosmological hydrodynamical simulations provide key predictions for the dynamical state of IGL and ICL and find that most IC stars are dissolved from galaxies that subsequently merge with the central galaxy. The increase of the measured velocity dispersion with radius in the outer halos of bright galaxies is a physical feature that makes it possible to identify IGL and ICL components. In the local groups and clusters, IGL and ICL are located in the dense regions of these structures. Their light fractions relative to the total luminosity of the satellite galaxies in a given group or cluster are between a few to ten percent, significantly lower than the average values in more evolved, more distant clusters. IGL and ICL in the Leo I and M49 groups, and the Virgo cluster core around M87, has been found to arise from mostly old (>~10 Gyr) metal-poor ([Fe/H]<-1.0) stars of low-mass progenitor galaxies. New imaging facilities such as LSST, Euclid, and the `big eyes' on the sky - ELT and JWST with their advanced instrumentation-promise to greatly increase our knowledge of the progenitors of the IGL and ICL stars, their ages, metal content, masses and evolution, thereby increasing our understanding of this enigmatic component.

description: Статья посвящена осмыслению истории лингвистического изучения произведений Роберта Бернса в России. Отмечается, что первые статьи, посвященные языку и стилю поэзии Бернса, были опубликованы в позднесоветский период (1970 – 1980-е гг.) Н.П. Микериной, Т.И. Воронцовой, А.А. Голиковым, Т.А. Ледовской. В работах Н.П. Микериной, посвященных изучению словесной образности в английской поэзии, произведения шотландского автора ис- пользовались в качестве иллюстраций, обоснования теоретических суждений. Работы Т.Н. Воронцовой, написанные на материале баллады Бернса «Джон Ячменное Зерно», выполнены в русле исследований лингвистики текста. Наибольшее значение имели статьи А.А. Голикова и Т.А. Ледовской, однако первая из них опиралась преимущественно на литературоведческие концепции, а вторая подводила к спорным выводам. При всей неоднозначности подходов исследователей к языку и стилю поэзии Бернса можно высоко оценивать сам факт появления в печати этих статей, свидетельствовавший о несомненном усилении внимания к языково-стилистическим особенностям бернсовского наследия в отечественной филологической науке.

description: Diese These befasst sich mit dem Zusammenhang zwischen Handel und menschlicher Entwicklung. Wir untersuchen wie sich der Handel auf den HDI auswirken kann indem wir den Human Development Index (HDI) zu einem Paneldatensatz hinzufügen. Mithilfe eines GMM-Schätzers bestätigen wir die Erkenntnisse aus der Literatur, dass der Handel erhebliche Auswirkungen auf den normalen HDI und den Nichteinkommen-HDI hat. Den aktuellen Daten zufolge scheint der einkommensunabhängige HDI jedoch hauptsächlich vom Handel zwischen den ärmsten Einkommensgruppen beeinflusst zu werden, was darauf hindeutet, dass der Handel auch über einkommensunabhängige Kanäle Vorteile bringt. Dies deutet darauf hin, dass Lebenserwartung und Bildung durch den Handel in den ärmsten Ländern gestiegen sind.
description: This thesis concerns the relationship between trade and human development. By using adding the human development index (HDI) to a panel data set, we study how per capita trade can impact HDI when regular HDI is used, and when non-income HDI is used. Using a GMM estimator, we confirm the finding in the literature that trade significantly impacts regular HDI and non-income. However, with current data, non-income HDI appears to be mostly impacted by trade among the poorest income groups, which suggests that there are benefits to trade, even though non-income channels. This suggests that trade is not only about income and that life expectancy and education have been increased due to trade in the poorest countries.

description: Parents of autistic children are routinely advised to raise them monolingually, despite potential negative effects of monolingualism and no evidence of harm from bilingualism. There is, however, limited research on this topic. This study explored experiences and perspectives of educational practitioners ('practitioners') and parents of Hebrew-English bilingual autistic children on bilingualism and monolingualism. Using interpretative phenomenological analysis, we explored the experiences of 22 parents and 31 practitioners using both oral and written interviews. The analysis revealed that religious continuity is a crucial factor in bilingual decision-making. Unexpectedly, both practitioners and parents felt that having to adopt a monolingual approach was unjust, in line with conceptions of forced monolingualism. This article recommends awareness training on community languages and research in other communities.

description: В статье предпринята попытка лингвокультурологического анализа концепта «дерево / мас» на материале русской и якутской лингвокультур. Национально-культурная маркированность концепта позволяет характеризовать его как средство ритуальной цели, универсальную модель Вселенной, систему пространственных и духовных координат. Авторами проанализировано содержание лексикографических источников: словарные дефиниции лексемы, репрезентирующей концепт «дерево/мас», представляют подробную структурно-содержательную характеристику ментального образования. С формальной точки зрения выделены прямые значения и переносные. Прямое значение указывает непосредственно на денотат (дерево/мас как вид растения, ботаническое явление). Переносные производные значения номинации, основанные на синекдохе (древесина и материал для строительства и изготовления предметов), связаны с реальными объектами окружающей человека действительности. Установлено, что вторичные значения номинаций дерево/мас, имея различную мифологическую составляющую, представляют определенные фрагменты картины мира человека. Следующим этапом в исследовании особенностей концепта дерево/мас стало изучение данных мифологии и фольклора русского и якутского народов. Дерево в русской культуре занимает особое место. Славяне, живущие в лесах, относились к деревьям с большим почтением, наделяя почти каждое сверхъестественными свойствами. Дерево связует земной и небесный миры, точно так же дерево соединяет мир подземный с земным. В картине мира тюрков дерево тесно связано с жизнью членов рода. Так как, согласно архаическому мировоззрению, главное свойство дерева – необычайная сила и плодовитость, то оно является символом жизни и залогом благополучия членов рода. Авторами статьи сделан вывод о том, что объединяющим моментом у многих народов мира, в том числе русского и якутского, является образ Мирового древа, древа жизни.
