description: The late-time integrated Sachs-Wolfe (ISW) signal in the CMB temperature anisotropies is an important probe of dark energy when it can be detected by cross-correlation with large-scale structure surveys. Because of their huge sky area, surveys in the radio are well-suited to ISW detection. We show that 21cm intensity mapping and radio continuum surveys with the SKA in Phase~1 promise a $\sim5σ$ detection if we use tomography, with a similar forecast for the precursor EMU survey. In SKA Phase~2, the 21cm galaxy redshift survey and the continuum survey could deliver a $\sim6σ$ detection. Our analysis of the radio surveys aims for theoretical accuracy on large scales. Firstly, we include all the effects on the radio surveys from observing on the past lightcone: redshift-space distortions and lensing magnification can have a significant impact on the ISW signal to noise ratio, while Doppler and other relativistic distortions are not significant. Secondly, we use the full information in the observable galaxy angular power spectra $C_\ell(z,z')$, by avoiding the Limber approximation and by including all cross-correlations between redshift bins in the covariance. Without these cross-bin correlations, the ISW signal to noise ratio is biased.

description: No abstracts are to be cited without prior reference to the author.Cod, haddock, and whiting are among the most economically important species in the Scottish demersal fishery. Juvenile settlement, the transition from pelagic to demersal habitat, has been identified as an important milestone for these species, but there is insufficient knowledge and data on this life stage. It is believed that the period of settlement has an impact on recruitment success, as important density‐dependent processes may take place, such as competition for suitable substrate, refuge or prey. Also, knowledge of settlement timing and duration is relevant to understanding population connectivity and thus to the development of successful conservation measures. Sampling was conducted between April and August 2004, June and September 2005, and June and July 2006 at an inshore site off the east coast of Scotland. Over 4000 0‐group cod, haddock, and whiting were collected. The results demonstrated that the transition from the pelagic to the demersal habitat was associated with clear and progressive changes in the prey composition of the juvenile fish. The size of fish that could be considered settled was estimated for cod at 4.9 (±0.3) cm, haddock at 7.8 (±0.4) cm, and whiting at 8.5 (±0.6) cm. The results also suggested clear differences in the patterns of settlement between the different species. Initially juvenile haddock favoured deeper, further offshore locations, while cod occupied shallower, inshore waters. Whiting settled much later in the season and over a protracted period of time.

description: We analyze virtual Compton scattering off the nucleon at low energies in a covariant, model-independent formalism. We define a set of invariant functions which, once the irregular nucleon pole terms have been subtracted in a gauge-invariant fashion, is free of poles and kinematical zeros. The covariant treatment naturally allows one to implement the constraints due to Lorentz and gauge invariance, crossing symmetry, and the discrete symmetries. In particular, when applied to the $ep\to e'p'γ$ reaction, charge-conjugation symmetry in combination with nucleon crossing generates four relations among the ten originally proposed generalized polarizabilities of the nucleon.

description: Radio emission from air showers enables measurements of cosmic particle kinematics and identity. The radio signals are detected in broadband Megahertz antennas among continuous background noise. We present two deep learning concepts and their performance when applied to simulated data. The first network classifies time traces as signal or background. We achieve a true positive rate of about 90% for signal-to-noise ratios larger than three with a false positive rate below 0.2%. The other network is used to clean the time trace from background and to recover the radio time trace originating from an air shower. Here we achieve a resolution in the energy contained in the trace of about 20% without a bias for $80\%$ of the traces with a signal. The obtained frequency spectrum is cleaned from signals of radio frequency interference and shows the expected shape.

Focus Questions
Creators: name: Athanasiadou, Angeliki
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1991

description: Focus plays an important role in questions and it is controlled by the intentions of the speakers and the preceding context. The speakers’ intentions concerning the localization of a constituent can be traced through (a) structural devices for expressing focus in questions and (b) pragmatic reasons that underlie the assignment of focus to that part of structure. Thus, the main purpose of this paper is to elicit the devices that the speaker uses when he intends to focalize a constituent in a question. Focal information may be new to the hearer since there is difference between the pragmatic information of the speaker and the speaker's picture of the pragmatic information of the hearer. However, it may not be completely new; it may include information already available to the hearer but focussed on by virtue of some implicit or explicit contrast. Contrasted focus may replace, expand, restrict or select pieces of information for the hearer to know. Focus is manifested through one or more of the following devices: prosodic prominence, word order, lexical selection for focus (wh-element, quantifiers, adjectives...), special focus constructions (clefting, negation).

description: We show that vortex nucleation in superfluid $^3$He by rapid thermal quench in the presence of superflow is dominated by a transverse instability of the moving normal-superfluid interface. Exact expressions for the instability threshold as a function of supercurrent density and the front velocity are found. The results are verified by numerical solution of the Ginzburg-Landau equation.

description: When a star approaches a black hole closely, it may be pulled apart by gravitational forces in a tidal disruption event (TDE). The flares produced by TDEs are unique tracers of otherwise quiescent supermassive black holes (SMBHs) located at the centre of most galaxies. In particular, the appearance of such flares and the subsequent decay of the light curve are both sensitive to whether the star is partially or totally destroyed by the tidal field. However, the physics of the disruption and the fall-back of the debris are still poorly understood. We are here modelling the hydrodynamical evolution of realistic stars as they approach a SMBH on parabolic orbits, using for the first time the moving-mesh code AREPO, which is particularly well adapted to the problem through its combination of quasi-Lagrangian behaviour, low advection errors, and high accuracy typical of mesh-based techniques. We examine a suite of simulations with different impact parameters, allowing us to determine the critical distance at which the star is totally disrupted, the energy distribution and the fallback rate of the debris, as well as the hydrodynamical evolution of the stellar remnant in the case of a partial disruption. Interestingly, we find that the internal evolution of the remnant's core is strongly influenced by persistent vortices excited in the tidal interaction. These should be sites of strong magnetic field amplification, and the associated mixing may profoundly alter the subsequent evolution of the tidally pruned star.

Here we report the thin film fabrication of the single phase of Mn$_3$Sn and the observation of the large anomalous Hall effect at room temperature despite its vanishingly small magnetization. Our work on the high-quality thin film growth of the Weyl antiferromagnet paves the path for developing the antiferromagnetic spintronics.

description: Tropical cyclones that evolve from a non-tropical origin may pose a special challenge for predictions, as they often emerge at the end of a multi-scale cascade of atmospheric processes. Climatological studies have shown that the 'tropical transition' (TT) pathway plays a prominent role in cyclogenesis, in particular over the North Atlantic Ocean. Here we use operational European Centre for Medium-Range Weather Forecasts ensemble predictions to investigate the TT of North Atlantic Hurricane Chris (2012), whose formation was preceded by the merger of two potential vorticity (PV) maxima, eventually resulting in the storm-inducing PV streamer. The principal goal is to elucidate the dynamic and thermodynamic processes governing the predictability of cyclogenesis and subsequent TT. Dynamic time warping is applied to identify ensemble tracks that are similar to the analysis track. This technique permits small temporal and spatial shifts in the development. The formation of the pre-Chris cyclone is predicted by those members that also predict the merging of the two PV maxima. The position of the storm relative to the PV streamer determines whether the pre-Chris cyclone follows the TT pathway. The transitioning storms are located inside a favorable region of high equivalent potential temperatures that result from a warm seclusion underneath the cyclonic roll-up of the PV streamer. A systematic investigation of consecutive ensemble forecasts indicates that forecast improvements are linked to specific events, such as the PV merging. The present case exemplifies how a novel combination of Eulerian and Lagrangian ensemble forecast analysis tool allows to infer physical causes of abrupt changes in predictability.

description: We present novel algorithms to estimate outcomes for qubit quantum circuits. Notably, these methods can simulate a Clifford circuit in linear time without ever writing down stabilizer states explicitly. These algorithms outperform previous noisy near-Clifford techniques for most circuits. We identify a large class of input states that can be efficiently simulated despite not being stabilizer states. The algorithms leverage probability distributions constructed from Bloch vectors, paralleling previously known algorithms that use the discrete Wigner function for qutrits.

description: The crystallization and magnetic behavior of yttrium iron garnet (YIG) prepared by metallo-organic decomposition (MOD) method are discussed. The chemistry and physics related to synthesis of iron and yttrium carboxylates based on 2-ethylhexanoic acid (2EHA) are studied, since no literature was found which elucidates synthesis of metallo-organic precursor of YIG in spite of the literatures of doped YIG samples such as Bi-YIG. Typically, the metal carboxylates used in preparation of ceramic oxide materials are 2-ethylhexanoate (2EH) solvents. Herein, the synthesis, thermal behavior and solubility of yttrium and iron 2EH used in synthesis of YIG powder by MOD are reported. The crystallization and magnetic parameters, including saturation magnetization and coercivity of these samples, smoothly change as a function of the annealing temperature. It is observed that high sintering temperature of 1300 to 1400 °C promotes the diffraction peaks of YIG, therefore, we can conclude that the formation of YIG in MOD method increases the crystallization temperature. The maximum value of saturation magnetization and minimum value of coercivity and remanence are observed for the sample sintered at 1200°C which are 13.7 emu/g, 10.38 Oe and 1.5 emu/g, respectively. This study cites the drawbacks in chemical synthesis of metallo-organic based YIG production.

description: Modified Laplace transformation method is applied to N component $ϕ^4$ theory and the finite temperature problem in the massless limit is re-examined in the large N limit. We perform perturbation expansion of the dressed thermal mass in the massive case to several orders and try the massless approximation with the help of modified Laplace transformation. The contribution with fractional power of the coupling constant is recovered from the truncated massive series. The use of inverse Laplace transformation with respect to the mass square is crucial in evaluating the coefficients of fractional power terms.

Assuming large statistics from identified blazars, collected in the forthcoming years by the IceCube detector and its successor IceCube-Gen2, we demonstrate that the constraints on several new physics scenarios in which the baseline dependent terms in neutrino oscillation probabilities are not averaged, can be improved. As a representative case, we consider pseudo-Dirac neutrinos while neutrino decay is also discussed.

description: No abstracts are to be cited without prior reference to the author.A potential consequence of climate change on species with pelagic larvae is that shifts in the timing of larval release or of food availability may cause variation in recruitment governed by match/mismatch mechanisms. Species may avoid mismatch by synchronizing larval release to pulses of food or may develop physiological adaptations to tolerate low food levels. In the UK, the barnacle Semibalanus balanoides releases larvae in response to the spring phytoplankton bloom, whereas Elminius modestus releases larvae over a longer summer period. We experimentally tested if the pattern of larval release of S. balanoides in response to food density was related to larval food limitation and whether or not larvae of E. modestus display higher tolerance of food limitation than S. balanoides. Larvae of both species were reared under three food levels of Skeletonema costatum (4 × 105; 2 × 105, and 0.4 × 105 cells ml–1), reproducing those known to affect S. balanoides larval release. Larvae were obtained from eight adults to account for parental influences on larval tolerance. Experiments were run at 15°C, where larval survival of both species is reportedly high. Duration of development was shorter for both species under highest food density. No differences in survival and success of metamorphosis to juvenile were observed for E. modestus. In S. balanoides the lowest food density led to a significant reduction in survival and rates of metamorphosis to juvenile. This pattern was consistent across larvae from different adults although there was a highly significant parental influence.

description: In this paper, we continue investigating the possible values of the pre-factors $α$ and $β$ in the logarithmic corrected entropy-area relation based on cosmological stability arguments. In a previous study, we have investigated the stability of the entropy-corrected cosmology using an empirical hyperbolic form of the scale factor. We found that the zero values of the two pre-factors are necessary to obtain a stable flat universe with a deceleration-acceleration transition and no causality violation. The necessity of the zero values of the two pre-factors has also been reached in the current work using a hybrid scale factor Ansatz in the entropy-corrected cosmological equations. Investigating the corrected entropy-area relation in different gravitational and cosmological contexts can provide an accurate estimation to the correct values of the pre-factors. The current work opens a discussion on the validity of the correction terms in the logarithmic corrected entropy-area relation on the cosmological scale. The evolution of the cosmic pressure, energy density, equation of state parameter, jerk parameter and the nonlinear energy conditions has been analyzed.

description: No abstracts are to be cited without prior reference to the author.The controls of recruitment are conceptually multiple and potentially changeable over the years. In effect, recruitment results from many processes during spawning, larval drift, and the juvenile stage. Coupled physical biogeochemical models now provide realistic hindcasts that spatially resolve environmental conditions. Such information is useful to identify limiting conditions over the different habitats of the different life cycle stages. Environmental indices can be estimated and serve as indicators of processes favouring or limiting recruitment, allowing us to revisit conceptual understanding, such as the importance of retention or match–mismatch. This approach was applied to anchovy in the Bay of Biscay, for which a series of low recruitments occurred recently that previous understanding and regression models could not explain. Indices of physical features were estimated (river plumes, gyres, stratification, fronts) as well as indices of larval dispersal, primary production, and temperature. Also estimated were indices of spawning aggregations derived from fisheries survey data. The indices were estimated in different areas and seasons corresponding to the habitats of spawning adults, larvae, and juveniles. Limiting factors were searched for by evaluating the statistical significance of a quantile regression fit between the recruitment series and each index. Results demonstrated that the larval period was where many indices responded, confirming that it is a critical period. The limiting factors changed across the series, confirming the multiple nature of the determinism of recruitment. The danger of spurious correlation when searching many indicators is discussed. Rather than predict recruitment, monitoring a suite of indicators is advised.

description: We present the first all-sky catalogue of galaxy clusters and cluster candidates obtained from joint X-ray-SZ detections using observations from the Planck satellite and the ROSAT all-sky survey (RASS). The catalogue contains 2323 objects and has been validated by careful cross-identification with previously known clusters. This validation shows that 1597 candidates correspond to already known clusters, 212 coincide with other cluster candidates still to be confirmed, and the remaining 514 are completely new detections. With respect to Planck catalogues, the ComPRASS catalogue is simultaneously more pure and more complete. Based on the validation results in the SPT and SDSS footprints, the expected purity of the catalogue is at least 84.5%, meaning that more than 365 clusters are expected to be found among the new or still to be confirmed candidates with future validation efforts or specific follow-ups.

description: This RSM draft unites hyperbolic Mathieu theory, fractal recursion, phase holonomy, and harmonic overtone duality into a publication-ready no-code manuscript.

 It charts discrete curvature valves at 60, 121, 144, 168 Hz (and beyond), correlates them with fold-counts m=4,4+,12,8,, and generalizes to stellated polyhedral valves (Stella Octangula, rhombic-dodecahedral honeycomb).

A concise methods appendix on “Mathieu dispersion for γ-shelf ellipse” and a Phase-Holonomy (Hopf–π) plot close the skeptic’s loophole. This cross-platform blueprint promises immediate impact in acoustics, photonics, spintronics, and cognitive wave dynamics.

A single, even a cheap table-top apparatus furnishes the first material proof of RSM’s low-order recursion ladder. The four milestones at 60, 121, 144, 168 Hz choreograph a complete “seed–beat–valve–bridge” story, spanning square symmetry to cubic stellation and locking a Berry phase of π.

description: Δρ. Tatiana Borisova Ο αισθητικός παράγοντας του λόγου στο ιεραποστολικό έργο του Βυζαντίου και στην πρώιμη σλαβωνική γραμματεία: βάσει την σλαβικής μετάφρασης του ποιητικού αλφαβηταρίου του Αγίου Γρηγορίου του Θεολόγου Η παρούσα μελέτη επιχειρεί να προσεγγίσει το πολυσυζητημένο πρόβλημα της μετάδοσης της αισθητικής αντίληψης του λόγου που χαρακτηρίζει τον Βυζαντινό πολιτισμό στην Εκκλησιαστική Σλαβονική γραμματεία. Είναι γνωστό ότι ο αισθητικός παράγοντας του χριστιανικού πολιτισμού έπαιζε σημαντικό ρόλο στη Βυζαντινή ιεραποστολή προς τους Σλάβους. Οι συγκεκριμένοι τρόποι με τους οποίους όμως επιχειρούνταν η μετάβαση και η ακόλουθη προσαρμογή της Βυζαντινής τέχνης του λόγου στην Εκκλησιαστική Σλαβονική γλώσσα παραμένουν αδιερεύνητοι. Μερικές πτυχές αυτής της πολύπλοκης διαδικασίας προσπαθούμε να αναλύσουμε βάσει της σλαβικής μετάφρασης του ιαμβικού Αλφαβητάριου του Αγίου Γρηγορίου του Θεολόγου. Η συγκεκριμένη μετάφραση που ανάγεται στις πρώιμες φάσεις των Σλαβικών γραμμάτων συντάχθηκε στον Νότιο Σλαβικό χώρο αλλά έφτασε σε μας με το μοναδικό χειρόγραφο Ανατολικής Σλαβικής προέλευσης. Η μελέτη επικεντρώθηκε στην απόδοση της αλφαβητικής ακροστιχίδας καθώς και των φωνητικών σχημάτων του λόγου, συγκεκριμένα της πρωτογενούς και δευτερογενούς παρήχησης. Η ανάλυση των μεταφραστικών τεχνικών δείχνει ότι σε αντίθεση με τις μεταγενέστερες μεταφράσεις ο Σλάβος λόγιος δεν επιχειρεί να καλύψει το χάσμα μεταξύ της πλούσιας γλώσσας του Ελληνικού κειμένου και του σχετικά φτωχού λεξιλογίου που διέθετε η Εκκλησιαστική Σλαβονική στις πρώτες δεκαετίες της γραπτής της παράδοσης. Συνειδητά περιορίζει τις μεταφραστικές του επιλογές σε λέξεις ήδη γνωστές στον Σλάβο αναγνώστη. Αυτό καθιστά εξαιρετικά δύσκολη τη μετάβαση των ποιητικών δομών, η οποία γίνεται στη συγκεκριμένη περίπτωση με τη δημιουργία στο μεταφρασμένο κείμενο καινούριων ρητορικών μέσων, που παρόλο που δεν αντιστοιχούν ακριβώς στο πρωτότυπο, βρίσκονται ωστόσο στο γενικό πνεύμα της ποιητικότητάς του. Αναμφίβολα ο μεταφραστής προσέγγισε το ελληνικό πρωτότυπο ως ποιητικό κείμενο και προσπάθησε να αποδώσει στη μετάφραση την ποιητική του δομή, αξιοποιώντας τα ποιητικά μέσα της γλώσσας αποδοχής. Τα αποτελέσματα της παρούσας μελέτης βοηθάνε στην κατανόηση των τρόπων με τους οποίους οι παρόμοιες μεταφραστικές δραστηριότητες συμβάλλουν στη θεμελίωση του ποιητικού συστήματος της Εκκλησιαστικής Σλαβονικής γλώσσας βάσει της δημιουργικής γλωσσικής ερμηνείας της Βυζαντινή κληρονομιάς.

Ο συγγραφέας του και ο χρόνος αντιγραφής του δεν έχουν προσδιοριστεί ακριβώς. Επίσης δεν έχει μελετηθεί ακόμα η κειμενική ιστορία του ελληνικού πρωτογράφου και η σχέση του με τα άλλα κείμενα που προέρχεται από το Βυζάντιο από τον 9ο αιώνα και εξής και τα οποία περιέχουν ειδήσεις για τους Αγίους 42 Μάρτυρες. Οι προτεινόμενες εδώ προκαταρκτικές παρατηρήσεις στο περίγραμμα των επιστημονικών προβλημάτων είναι μέρος μιας πιο αντικειμενικής μελέτης επάνω στην ιστορική και την πολιτισμική συνάφεια και εξήγηση ορισμένων από τις πρωιμότερες σλαβικές και παλαιοβουλγαρικές μεταφράσεις. Μέσω μιας σύνθετης ανάλυσης των συγκεκριμένων ιστορικών-φιλολογικών στοιχείων και των γλωσσικών δεδομένων, μελετώνται τα σχετικά με το κείμενο του Μαρτυρίου. Η ερμηνευτική μελέτη και η δημιουργία των διακειμενικών πεδίων επεκτάθηκε στον σχηματισμό και την εξάπλωση της τιμής των Αγίων 42 Μαρτύρων του Αμορίου στο Βυζάντιο μετά την Εικονομαχία και στη Νεοφώτιστη Βουλγαρία κατά το δεύτερο μισό του 9ου αιώνα.

description: For any asymptotically flat spacetime with a suitable causal structure obeying (a weak form of) Penrose's cosmic censorship conjecture and satisfying conditions guaranteeing focusing of complete null geodesics, we prove that active topological censorship holds. We do not assume global hyperbolicity, and therefore make no use of Cauchy surfaces and their topology. Instead, we replace this with two underlying assumptions concerning the causal structure: that no compact set can signal to arbitrarily small neighbourhoods of spatial infinity (``$i^0$-avoidance''), and that no future incomplete null geodesic is visible from future null infinity. We show that these and the focusing condition together imply that the domain of outer communications is simply connected. Furthermore, we prove lemmas which have as a consequence that if a future incomplete null geodesic were visible from infinity, then given our $i^0$-avoidance assumption, it would also be visible from points of spacetime that can communicate with infinity, and so would signify a true naked singularity.

description: Total derivative terms play an important role in the integration of conformal anomaly. In four dimensional space $4D$ there is only one such term, namely $\,{\square}R$. In the case of six dimensions $6D$ the structure of surface terms is more complicated, and it is useful to construct a basis of linear independent total derivative terms. We briefly review the general scheme of integrating anomaly and present the reduction of the minimal set of the surface terms in $6D$ from eight to seven.
description: Modified and seriously extended version, prepared for submission to a journal. The extention mainly concerns the origins of the identity which restricts the surface terms

description: In this paper we study the topological susceptibility of two-dimensional $U(N)$ gauge theories. We provide explicit expressions for the partition function and the topological susceptibility at finite lattice spacing and finite volume. We then examine the particularly simple case of the abelian $U(1)$ theory, the continuum limit, the infinite volume limit, and we finally discuss the large $N$ limit of our results.

On the Construction of Scattering Amplitudes for Spinning Massless Particles

description: In this paper the general form of scattering amplitudes for massless particles with equal spins s ($s s \to s s$) or unequal spins ($s_a s_b \to s_a s_b$) are derived. The imposed conditions are that the amplitudes should have the lowest possible dimension, have propagators of dimension $m^{-2}$, and obey gauge invariance. It is shown that the number of momenta required for amplitudes involving particles with s > 2 is higher than the number implied by 3-vertices for higher spin particles derived in the literature. Therefore, the dimension of the coupling constants following from the latter 3-vertices has a smaller power of an inverse mass than our results imply. Consequently, the 3-vertices in the literature cannot be the first interaction terms of a gauge-invariant theory. When no spins s > 2 are present in the process the known QCD, QED or (super) gravity amplitudes are obtained from the above general amplitudes.

description: Although COVID-19 vaccines are an effective public health tool to combat the global pandemic, serious adverse events, such as hemophagocytic lymphohistiocytosis (HLH), caused by them are a concern. In this systematic review, cases of HLH reported after COVID-19 vaccination have been examined to understand the relationship between the two and propose effective therapeutic strategies. Furthermore, ruxolitinib’s potential as a cytokine inhibitor and its affinity for CD25 were initially assessed through molecular docking, aiming to aid targeted HLH therapy. PubMed and Web of Science databases were searched for published individual case reports on the occurrence of HLH after the administration of any COVID-19 vaccine. A total of 17 articles (25 patients) were included in this qualitative analysis. Furthermore, molecular docking was employed to investigate the therapeutic potential of ruxolitinib for HLH after COVID-19 vaccination. The mean age of patients who developed HLH after COVID-19 vaccination was 48.1 years. Most HLH episodes occurred after the BNT162b2 mRNA COVID-19 vaccination (14/25 cases) and to an extent after the ChAdOx1 nCov‐19 vaccination (5/25 cases). Almost all affected patients received steroid and antibiotic therapy. Three patients died despite treatment because of esophagus rupture, neutropenic fever, bacteroides bacteremia, refractory shock, and encephalopathy and shock. Visual docking results of IL-2 Rα and ruxolitinib using the Discovery Studio 2019 Client software yielded a model score of 119.879. The findings highlight the importance of considering and identifying the adverse effects of vaccination and the possibility of using ruxolitinib for treating HLH after COVID-19 vaccination.

description: Area-level estimates of temperature might lead to exposure misclassification in studies examining associations between heat waves and health outcomes. Our study compared the association between heat waves and preterm birth (PTB) or nonaccidental death (NAD) using exposure metrics at varying levels of spatial resolution: ZIP codes, 12.5 km, and 1 km. Using geocoded residential addresses on birth (1990–2010) and death (1997–2010) records from Alabama, we implemented a time-stratified case–crossover design to examine the association between heat waves and PTB or NAD. ZIP code and 12.5-km heat wave indexes (HIs) were derived using air temperatures from Phase 2 of the North American Land Data Assimilation System (NLDAS–2). We downscaled NLDAS–2 data, using land surface temperatures from the Moderate Resolution Imaging Spectroradiometer product, to estimate fine spatial resolution HIs (1 km). The association between heat waves and PTB or NAD was significant and positive using ZIP code, 12.5-km, and 1-km exposure metrics. Moreover, results show that these three exposure metric analyses produced similar effect estimates. Urban heat islands were evident with the 1-km metric. When analyses were stratified by rurality, we found that associations in urban areas were more positive than those in rural areas. Comparing results of models with a varying spatial resolution of the exposure metric allows for examination of potential bias associated with exposure misclassification.

description: The Translation of the Orationes Contra Arianos of Athanasius the Great in the First Bulgarian Kingdom Translation of Contra Arianos of Athanasius the Great in the 1st Bulgarian kingdom“ is a research of the earliest Slavonic tradition of the MSS of this work. The order of the books in the collection in question and the missing texts in it, point at an earlier Greek version of the collection which comes perhaps from the 9th or the 10th century and that can be found in Codex Atheniensis graecus 428. Linguistic characteristics of the translation fasten it to the Preslava School in North-East Bulgaria in the period of the 1st Bulgarian kingdom. The specific theological interest in this collection points at presence of Arians in the region.

description: A poset-stratified space is a pair $(S, S \xrightarrow πP)$ of a topological space $S$ and a continuous map $π: S \to P$ with a poset $P$ considered as a topological space with its associated Alexandroff topology. In this paper we show that one can impose such a poset-stratified space structure on the homotopy set $[X, Y]$ of homotopy classes of continuous maps by considering a canonical but non-trivial order (preorder) on it, namely we can capture the homotopy set $[X, Y]$ as an object of the category of poset-stratified spaces. The order we consider is related to the notion of \emph{dependence of maps} (by Karol Borsuk). Furthermore via homology and cohomology the homotopy set $[X,Y]$ can have other poset-stratified space structures. In the cohomology case, we get some results which are equivalent to the notion of \emph{dependence of cohomology classes} (by René Thom) and we can show that the set of isomorphism classes of complex vector bundles can be captured as a poset-stratified space via the poset of the subrings consisting of all the characteristic classes. We also show that some invariants such as Gottlieb groups and Lusternik--Schnirelmann category of a map give poset-stratified space structures to the homotopy set $[X,Y]$
