description: На основании опубликованных данных, архивных материалов и результатов оригинальных исследований выявлен ряд изменений, произошедших в растительном покрове оз. Плещеево с 1899 по 2017 гг. Видовой состав флоры озера остается стабильным на протяжении последних 20 лет и насчитывает 133 вида макрофитов. Достоверно зафиксировано исчезновение 1 вида (Caulinia flexilis). 8 видов прибрежно-водных и водных растений включены в основной список Красной книги Ярославской обл. Состав и площади растительных сообществ на литорали изменилось более значительно. Последние 20 лет не отмечались ценозы Chara sp., которые раньше были типичны для водоема. Произошло сокращение площадей сообществ некоторых погруженных гидрофитов (Eleocharis acicularis , Zanichellia palustris), уменьшение проективного покрытия характерных для озера ценозов (Potamogeton perfoliatus , Ranunculus circinatus), и, наоборот, ранее почти не представленные сообщества (Cladophora sp., Ceratophyllum demersum , Elodea canadensis) стали более значимы в растительном покрове. Наблюдается незначительное возрастание площадей прибрежно-водной растительности (особенно сообществ Phragmites australis ). Эти процессы связаны с естественным старением водоема и возрастанием антропогенной нагрузки. Общая степень зарастания озера остается низкой (~5%) и не будет возрастать в ближайшей и отдаленной перспективе из-за незначительной площади литорали, доступной для водных растений, преобладания песчаного грунта и гидродинамических особенностей водоема.

Exploring asymmetric multifractal cross-correlations of price-volatility and asymmetric volatility dynamics in cryptocurrency markets

description: Asymmetric relationship between price and volatility is a prominent feature of the financial market time series. This paper explores the price-volatility nexus in cryptocurrency markets and investigates the presence of asymmetric volatility effect between uptrend (bull) and downtrend (bear) regimes. The conventional GARCH-class models have shown that in cryptocurrency markets, asymmetric reactions of volatility to returns differ from those of other traditional financial assets. We address this issue from a viewpoint of fractal analysis, which can cover the nonlinear interactions and the self-similarity properties widely acknowledged in the field of econophysics. The asymmetric cross-correlations between price and volatility for Bitcoin (BTC), Ethereum (ETH), Ripple (XRP), and Litecoin (LTC) during the period from June 1, 2016 to December 28, 2020 are investigated using the MF-ADCCA method and quantified via the asymmetric DCCA coefficient. The approaches take into account the nonlinearity and asymmetric multifractal scaling properties, providing new insights in investigating the relationships in a dynamical way. We find that cross-correlations are stronger in downtrend markets than in uptrend markets for maturing BTC and ETH. In contrast, for XRP and LTC, inverted reactions are present where cross-correlations are stronger in uptrend markets.

description: We study how decoherence rules the quantum-classical transition of the Kicked Harmonic Oscillator (KHO). When the amplitude of the kick is changed the system presents a classical dynamics that range from regular to a strong chaotic behavior. We show that for regular and mixed classical dynamics, and in the presence of noise, the distance between the classical and the quantum phase space distributions is proportional to a single parameter $χ\equiv K\hbar_{\rm eff}^2/4D^{3/2}$ which relates the effective Planck constant $\hbar_{\rm eff}$, the kick amplitude $K$ and the diffusion constant $D$. This is valid when $χ< 1$, a case that is always attainable in the semiclassical regime independently of the value of the strength of noise given by $D$. Our results extend a recent study performed in the chaotic regime.

description: Unsafe abortion is one of the major medical and public health problems in developing countries including Ethiopia. Yet, there is no reliable information on induced abortion distribution and its determinant factors in the country. This study assesses the determinants of unsafe abortion among women of reproductive age group in Arsi Zone, Central Ethiopia. Institution based cross-sectional study was conducted in four health facilities in Arsi zone. Client exit interview was conducted on 268 patients using a structured questionnaire and semi-structured guide for in-depth interview with key informants. Bivariate and multivariate logistic regression analyses were performed to identify the factors associated with unsafe abortion. Thematic analysis was done in this study. For variables having association in bivariate logistic regression, multivariate logistic regression test was employed. About 115 (42.9%) underwent unsafe abortion; they were about 15 to 19 years (AOR = 12.5; 95% CI: 3.24, 48.3), 20 to 24 years (AOR= 3.98; 95% CI: 1.27, 12.4) and had no formal education (AOR = 4.3; 95% CI: 1.67, 11.14). The study shows the high level of unsafe abortion to capture the attention of programmers and implementers to prevent unwanted pregnancy and make post abortion care accessible.

description: В 2013-2016 гг. изучены основные характеристики макробентоса биоценоза Dreissena polymorpha Pallas 1771 в оз. Плещеево. Биоценоз дрейссены вносит довольно весомый вклад в формирование донной фауны озера. Здесь отмечено более 65% всех отмеченных нами таксонов рангом ниже рода. Основу видового богатства и обилия бентоса в биоценозе дрейссены составляли хирономиды и олигохеты, вместе с дрейссеной формирующие основу кормовой базы для рыб-бентофагов. Видовое разнообразие бентоса в биоценозе дрейссены в оз. Плещеево немного выше, чем в литорали и практически в два раза выше, чем в профундали водоема и сопоставимо с разнообразием в биоценозе дрейссены в других водоемах. В трофической структуре значительная доля принадлежит фитодетритофагам-фильтраторам+собирателям. При сравнении с предыдущими исследованиями выявлено увеличение вклада мелких моллюсков в формирование биомассы макробентоса в биоценозе дрейссены. Отмечена тенденция к снижению обилия донных макробеспозвоночных без учета мегабентоса (крупных моллюсков р. Dreissena и Unio ).

description: За период 2013-2017 гг. проведен анализ морфо-экологических характеристик переславской ряпушки - эндемичной популяции европейской ряпушки, населяющей оз. Плещеево. Проанализированы особенности размерно-возрастной и половой структур популяции, плодовитость и темп роста. Показано, что основными тенденциями в современной популяции переславской ряпушки являются уменьшение размеров рыб, снижение темпа роста и плодовитости самок. Эти изменения вызваны снятием с нее промысловой нагрузки в конце прошлого века, в результате чего произошло увеличение численности переславской ряпушки. Замедление темпов роста и уменьшение линейных размеров являются результатами усилившейся внутривидовой конкуренции, наиболее остро проявляющейся в период формирования в озере летней придонной гипоксии.В работе обсуждаются результаты сравнения морфологических признаков двух филогенетических линий ряпушки (E и ALBP2), в настоящее время обитающих в оз. Плещеево совместно, но имеющих разное происхождение. При выраженной генетической дифференциации линий, достигающей межвидового уровня, морфологически популяция однородна. Представители обеих линий принадлежат одному виду - Coregonus albula.

description: We propose a new hadronization mechanism, jet-fluid string (JFS) formation and decay, to understand observables in intermediate to high-$p_{T}$ regions comprehensively. In the JFS model, hard partons produced in jet lose their energy in traversing the QGP fluid, which is described by fully three-dimensional hydrodynamic simulations. When a jet parton escapes from the QGP fluid, it picks up a partner parton from a fluid and forms a color singlet string, then it decays to hadrons. We find that high-$p_T$ $v_2$ values in JFS are about two times larger than in the independent fragmentation model.

Методом световой микроскопии исследованы эритрограмма и лейкограмма на мазках периферической крови, подсчитаны объем эритроцита, его ядра, ядерно-цитоплазматическое отношение, индекс формы клетки. Показано, что в целом сезонная динамика изученных показателей подобна таковой других сиговых рыб. Вместе с тем, обнаружены отличия от показателей ряпушки, выловленной в Рыбинском водохранилище. У ряпушки из оз. Плещеево в периферической крови доля бластных клеток как красной, так и белой крови составляет от 0.8 до 1%, незрелых эритроцитов 2-3%, зрелые эритроциты составляют 96-97%. Доля патологических эритроцитов незначительна и не превышает 0.1-0.2%. Следует отметить, что эритроциты у рыб из оз. Плещеево крупнее, чем у рыб из Рыбинского водохранилища. Среди лейкоцитов основную массу клеток составляют лимфоциты. Доля моноцитов достигает 4%. Выявленные отличия могут быть связаны с изменением температурного и кислородного режима водоема и эвтрофикацией.

description: A system for studying microcavity resonators at cryogenic temperatures (~10 K) through evanescent coupling via optical fiber taper waveguides is reported, and efficient fiber coupling to AlGaAs microdisk cavities with embedded quantum dots is demonstrated. As an immediate application of this tool, we study high-resolution tuning of microdisk cavities through nitrogen gas adsorption, as first discussed by Mosor, et al. By proper regulation of the nitrogen gas flow and delivery of the gas to the sample surface, continuous tuning can be achieved with modest gas flows, and overall wavelength shifts as large as 4 nm are achieved.

description: Ενσυναίσθηση θεωρείται η ικανότητα γνωσιακής διείσδυσης στην εσωτερική προοπτική ενός άλλου όντος. Διά μέσου της έκφρασης του άλλου όντος, επί παραδείγματι του ύφους του, βρίσκω ένα πέρασμα στην εσωτερική συναισθηματική κατάστασή του. Όταν βλέπω κάποιον θλιμμένο, γνωρίζω ότι είναι θλιμμένος. Αυτό σημαίνει πως υπάρχει μία κινητοποίηση εν μέρει εντός εμού και εν μέρει εκτός εμού, η οποία θέτει σε κίνηση μία νέα αντίληψη εντός εμού, το βίωμα του ξένου όντος. Αυτό που κινητοποιείται εντός μου δεν είναι συναίσθημα αλλά νοητική δραστηριότητα. Δεν αισθάνομαι κατ' ανάγκην αυτό που αισθάνεται ο άλλος, αλλά γνωρίζω πώς αισθάνεται και αρχίζω να κατανοώ το Είναι του. Η ενσυναίσθηση δεν είναι ούτε συμπόνια, ούτε συμπάθεια αλλά η προϋπόθεση της εμφάνισής τους. Ειδικότερα, η ενσυναίσθηση είναι η κοινή κατοχή των υποκειμενικών καταστάσεων ως αντικειμενικών, πράγμα το οποίο μας οδηγεί στην έννοια της διυποκειμενικότητας και της κατανόησης του αντικειμενικού κόσμου
description: Empathy is considered as the ability to possess knowledge of the inner perspective of another being. There is a passage for me through a foreign being's expression, for example the look on his face, to his inner state of feelings. When I see somebody looking sad, then I know he is sad. This means that there is a motivation partly within me and partly outside of me that motivates a new perception in me, the foreign being's experience. What is motivated in me is not a feeling but a mental activity. I do not necessarily feel what he feels but I know how he feels and I begin to understand his being. Empathy is neither compassion, nor sympathy but the precondition of their occurrence. In particular, empathy is the sharing of subjective states as objective which leads us to the concept of intersubjectivity and the understanding of the objective world

description: The X-ARAPUCA device is the baseline choice for the photon detection system of the first far detector module of the DUNE experiment. We present the results of the first complete characterization of a small scale X-ARAPUCA prototype, which is a slice of a full DUNE module. Its total detection efficiency in liquid argon was measured with three different ionizing radiations: $α$ particles, $γ$'s and muons and resulted to be $\sim$2.2% when the active silicon photomultipliers were biased at +5.0 V of over voltage, corresponding to a Photon Detection Efficiency around 50% at room temperature. This value comfortably satisfies the requirements of the first DUNE far detector module (detection efficiency $>$2.0%) and allows to achieve an energy resolution comparable to the one achievable with the Time Projection Chambers for energies below 10 MeV, which is the region relevant for Supernova neutrino detection.

description: We formulate the problem of magnetic field dissipation during the accretion phase of low-mass star formation, and we carry out the first step of an iterative solution procedure by assuming that the gas is in free-fall along radial field lines. This so-called ``kinematic approximation'' ignores the back reaction of the Lorentz force on the accretion flow. In quasi steady-state, and assuming the resistivity coefficient to be spatially uniform, the problem is analytically soluble in terms of Legendre's polynomials and confluent hypergeometric functions. The dissipation of the magnetic field occurs inside a region of radius inversely proportional to the mass of the central star (the ``Ohm radius''), where the magnetic field becomes asymptotically straight and uniform. In our solution, the magnetic flux problem of star formation is avoided because the magnetic flux dragged in the accreting protostar is always zero. Our results imply that the effective resistivity of the infalling gas must be higher by several orders of magnitude than the microscopic electric resistivity, to avoid conflict with measurements of paleomagnetism in meteorites and with the observed luminosity of regions of low-mass star formation.

description: We study the soft supersymmetry (SUSY) breaking terms due to the modulus F-term in the modular flavor models of leptons. It is found that the soft SUSY breaking terms are constrained by the modular forms, and specific patterns are derived. Those phenomenological implications are discussed in such as the lepton flavor violation, $μ\rightarrow e + γ$ decay. In order to examine numerically, two modular flavor $A_4$ models are taken. The SUSY breaking scale is significantly constrained by inputting the observed upper bound of the $μ\rightarrow e + γ$ decay. The SUSY mass scale is larger than around $8$ TeV and $5$ TeV for the two $A_4$ models, respectively. Therefore, the current experimental upper bound for the $μ\to e + γ$ decay corresponds to the new physics of the SUSY particle at the $5$ -- $10$ TeV scale in the modular flavor models. The predicted branching ratio depends on a modulus $τ$ significantly. It decreases of one order at the large ${\rm Im}\,τ$. We also calculate the branching ratios of tauon decays to $e + γ$ and $μ+ γ$. Predicted ones are at most ${\cal O}(10^{-15})$, which are much below the current experimental bounds.

description: Consider a rowwise independent triangular array of gamma random variables with varying parameters. Under several different conditions on the shape parameter, we show that the sequence of row-maximums converges weakly after linear or power transformation. Depending on the parameter combinations, we obtain both Gumbel and non-Gumbel limits. The weak limits for maximum of the coordinates of certain Dirichlet vectors of increasing dimension are also obtained using the gamma representation.

description: Η Συρία από το 2011 αποτελεί πεδίο ατέρμονης μάχης κυβερνητικών δυνάμεων, παραστρατιωτικών ομάδων και άλλων κρατών με στόχο την ουσιαστική κυριαρχία στη χώρα. Στον πόλεμο εμπλέκονται και εκπρόσωποι θρησκειών και Εκκλησιών. Η παρούσα ανάλυση καταλήγει στο συμπέρασμα ότι οι τελευταίοι στην πράξη, δεν έχουν ένα ειρηνευτικό ρόλο αλλά εξυπηρετούν εθνικά συμφέροντα σε μία προοπτική τυχοδιωκτικού επεκτατισμού
description: Syria, since 2011, has been an endless battleground between governmental forces, paramilitary groups and other states, aiming for the substantial sovereignty in the country. Representatives of religions, churches are also involved in the war. The current analysis concludes that the latter, in practice, do not have a peaceful role but they serve national interests in a prospect of adventurous expansionism

description: At the Large Hadron Collider (LHC), both the ATLAS and CMS Collaborations have been searching for light charged Higgs bosons via top (anti)quark production and decays channels, like $pp\to t \bar{t}$ with one top (anti)quark decaying into a charged Higgs boson and a $b$ (anti)quark, when the decay is kinematically open (i.e., when $m_{H^\pm}\lesssim m_t$). In this paper, we propose new searches at the LHC involving light charged Higgs bosons via their pair production channels like $pp\to H^\pm h/A$ and $pp\to H^+ H^-$ in the 2-Higgs Doublet Model (2HDM) Type-I and -X scenarios. By focusing on the case where the heavy $H$ state plays the role of the Standard Model (SM)-like Higgs boson with a mass near 125 GeV, we study the aforementioned Higgs boson pair production channels and investigate their bosonic decays, such as $H^\pm \to W^{\pm } h$ and/or $H^\pm \to W^{\pm } A$. We demonstrate that for a light charged Higgs boson state, with $m_{H^\pm}\lesssim m_t$, at the LHC, such di-Higgs production and decay channels can give rise to signatures with event rates much larger than those emerging from $pp\to t\bar{t}\to t\bar{b} H^-$ + c.c.. We specifically study $h/A\to b\bar b$ and $τ^+τ^-$ decays. We, therefore, claim that the discussed combination of new production and decay modes can result in an alternative discovery channel for charged Higgs bosons lighter than the top (anti)quark at the LHC within the above two 2HDM Types. Finally, in order to motivate experimentalists in ATLAS and CMS to search for such signatures, we propose 16 Benchmark Points (BPs) which are compatible with both theoretical and experimental constraints.

description: This study was conducted to address the bilingual language development of children with ASD, that live in bilingual environments. The purpose of the study is to present current research data regarding the bilingual development of children with ASD and the behavioural interventions that are implemented. Furthermore, a case study is presented. The aim of this case study is to examine the language skills that a 8:5 year old pupil with ASD has in Greek language, which he learns informally at L2 level. The pupil was examined using Applied Behavioural Analysis procedures, and his expressive, receptive and intraverbals skills were assessed. The results showed that the pupil has a wider receptive vocabulary compared to his expressive vocabulary, confirming the receptive-expressive “gap” that previous research data have suggested. Moreover, the reaction time and the verbal fluency were assessed in both of the languages (English and Greek) and the pupil’s performance in English (L1) was higher. The results are discussed in relation to the structure and organization of the bilingual mental lexicon and the conceptual representations. Lastly, the perspective of implementing a bilingual behavioural intervention and teaching Greek systematically are discussed and conclusions are presented
A Quantum Broadcasting Problem in Classical Low Power Signal Processing

description: We pose a problem called ``broadcasting Holevo-information'': given an unknown state taken from an ensemble, the task is to generate a bipartite state transfering as much Holevo-information to each copy as possible. We argue that upper bounds on the average information over both copies imply lower bounds on the quantum capacity required to send the ensemble without information loss. This is because a channel with zero quantum capacity has a unitary extension transfering at least as much information to its environment as it transfers to the output. For an ensemble being the time orbit of a pure state under a Hamiltonian evolution, we derive such a bound on the required quantum capacity in terms of properties of the input and output energy distribution. Moreover, we discuss relations between the broadcasting problem and entropy power inequalities. The broadcasting problem arises when a signal should be transmitted by a time-invariant device such that the outgoing signal has the same timing information as the incoming signal had. Based on previous results we argue that this establishes a link between quantum information theory and the theory of low power computing because the loss of timing information implies loss of free energy.

description: The upcoming Square Kilometre Array (SKA-Low) will map the distribution of neutral hydrogen during reionization, and produce a tremendous amount of 3D tomographic data. These images cubes will be subject to instrumental limitations, such as noise and limited resolution. Here we present SegU-Net, a stable and reliable method for identification of neutral and ionized regions in these images. SegU-Net is a U-Net architecture based convolutional neural network (CNN) for image segmentation. It is capable of segmenting our image data into meaningful features (ionized and neutral regions) with greater accuracy compared to previous methods. We can estimate the true ionization history from our mock observation of SKA with an observation time of 1000 h with more than 87 per cent accuracy. We also show that SegU-Net can be used to recover various topological summary statistics, such as size distributions and Betti numbers, with a relative difference of only a few per cent. These summary statistics characterise the non-Gaussian nature of the reionization process.

description: Calculations of nuclear masses, using nuclear density functional theory, are presented for even-even nuclei spanning the nuclear chart. The resulting binding energy differences can be interpreted in terms of valence proton-neutron interactions. These are compared globally, regionally, and locally with empirical values. Overall, excellent agreement is obtained. Discrepancies highlight neglected degrees of freedom and can point to improved density functionals.

description: Let S be an arbitrary scheme. We define biextensions of 1-motives by 1-motives which we see as the geometrical origin of morphisms from the tensor product of two 1-motives to a third one. If S is the spectrum of a field of characteristic 0, we check that these biextensions define morphisms from the tensor product of the realizations of two 1-motives to the realization of a third 1-motive. Generalizing we obtain the geometrical notion of morphisms from a finite tensor product of 1-motives to another 1-motive.

description: This dissertation presents a tripartite investigation into the relationship between the academic discipline of technical and professional communication (TPC) and user experience (UX) design and research. It argues that the work occurring in the liminal space between TPC and UX (TPC-UX) constitutes a mature communication design methodology that affords a bivalent consideration of both users and technologies. Following the introduction and literature review, this dissertation offers a content analysis of TPC-UX scholarship published between 2013-2022. The content analysis illustrates how TPC-UX affords (1) theoretical richness stemming from TPC’s longstanding engagement with social justice and post-humanism, (2) a robust consideration of multimodality owing to TPC-UX’s engagement with rhetorical theory, and (3) methodological flexibility that helps scholars and practitioners navigate complex communication contexts. Following the content analysis, this dissertation presents user research within a unique context—a newly formed, BIPOC-led nonprofit advocacy organization dedicated to equitable access to psychedelic assisted therapy. This chapter illustrates how volunteers’ UX with communication technologies is affected by both their motivations for volunteerism as well as organization development factors. In the final section, this dissertation describes an approach to TPC-UX pedagogy, wherein UX methods and deliverables are used to shape the development of a technology tutorial. This pedagogical approach demonstrates how UX is evolutionary, rather than revolutionary, for TPC pedagogy and affords students a greater engagement with the audiences and contexts of technical communication.

description: In a recent work [\textit{J. Mol. Liq}, 2020, \textbf{320}, 114420], using molecular dynamics simulations and a core-softened potential approach, we have shown that adding a simple solute as methanol can "kill" the density anomalous behavior as the LLCP is suppressed by the spontaneous crystallization in a hexagonal closed packing (HCP) crystal near the LLPT. Now, we extend this work in order to realize how longer-chain alcohols will affect the complex behavior of water-alcohol mixtures in the supercooled regime. Besides core-softened (CS) methanol, ethanol and 1-propanol were added to a system of identical particles that interact through the continuous shouldered well (CSW) potential. We observed that the density anomaly gradually decreases its extension in phase diagrams until disappearing with the growth of the non-polar chain and the alcohol concentration, differently from the liquid-liquid phase transition (and the LLCP), which remained present in all analyzed mixtures, in according to \textit{Nature}, 2001, \textbf{409}, 692. For our model, the longer non-polar chains and higher concentrations gradually impact the competition between the scales in the CS potential, leading to a gradual disappearing of the anomalies until the TMD total disappearance is observed when the first coordination shell structure is also affected: the short-range ordering is favored, leading to less competition between short- and long-range ordering and, consequently, to the extinction of anomalies. Also, the non-polar chain size and concentration have an effect on the solid phases, favoring the hexagonal closed packed (HCP) solid and the amorphous solid phase over the body-centered cubic (BCC) crystal.
The Spectrum of the Partially Locked State for the Kuramoto Model

description: We solve a longstanding stability problem for the Kuramoto model of coupled oscillators. This system has attracted mathematical attention, in part because of its applications in fields ranging from neuroscience to condensed-matter physics, and also because it provides a beautiful connection between nonlinear dynamics and statistical mechanics. The model consists of a large population of phase oscillators with all-to-all sinusoidal coupling. The oscillators' intrinsic frequencies are randomly distributed across the population according to a prescribed probability density, here taken to be unimodal and symmetric about its mean. As the coupling between the oscillators is increased, the system spontaneously synchronizes: the oscillators near the center of the frequency distribution lock their phases together and run at the same frequency, while those in the tails remain unlocked and drift at different frequencies. Although this ``partially locked'' state has been observed in simulations for decades, its stability has never been analyzed mathematically. Part of the difficulty is in formulating a reasonable infinite-N limit of the model. Here we describe such a continuum limit, and prove that the corresponding partially locked state is, in fact, neutrally stable, contrary to what one might have expected. The possible implications of this result are discussed.
