description: In superfluid dark matter (SFDM), the phonon field plays a double role: It carries the superfluid's energy density and it mediates the MOND-like phonon force. We show that these two roles are in tension with each other on galactic scales: A MOND-like phonon force is in tension with a superfluid in equilibrium and with a significant superfluid energy density. To avoid these tensions, we propose a model where the two roles are split between two different fields. This also allows us to solve a stability problem in a more elegant way than standard SFDM. We argue that the standard estimates for the size of a galaxy's superfluid core need to be revisited.

description: We report measurements of the in-plane magnetic penetration depth $Δλ$(T) in single crystals of ErNi$_{2}$B$_{2}$C down to $\sim$0.1 K using a tunnel-diode based, self-inductive technique at 21 MHz. We observe four features: (1) a slight dip in $Δλ$(T) at the N$\acute{e}$el temperature $T_{N}$ = 6.0 K, (2) a peak at $T_{WFM}$ = 2.3 K, where a weak ferromagnetic component sets in, (3) another maximum at 0.45 K, and (4) a final broad drop down to 0.1 K. Converting to superfluid density $ρ_{s}$, we see that the antiferromagnetic order at 6 K only slightly depresses superconductivity. We seek to explain some of the above features in the context of antiferromagnetic superconductors, where competition between the antiferromagnetic molecular field and spin fluctuation scattering determines increased or decreased pairbreaking. Superfluid density data show only a slight decrease in pair density in the vicinity of the 2.3 K feature, thus supporting other evidences against bulk ferromagnetism in this temperature range.

description: I examined diet, home range size, habitat use, and rest sites of short-tailed weasels (Mustela erminea) in the mixedwood boreal forest of Alberta. Of the 8 food groups identified in 585 scats, Arvicolidae, mainly red-backed voles (Clethrionomys gapperi), were the primary prey of weasels. In summer, weasels supplemented their diet with birds and eggs. Male weasels are 2- 3 times larger than females and included red squirrels (Tamiasciurus hudsonicus) in their summer and fall diets. Despite relatively high abundance of deer mice in my study area, this species was not exploited substantially by weasels. I radio-collared 7 female and 10 male short-tailed weasels. Female (n=4) and male (n=4) weasels had home range sizes of 65.5-94.8 ha and 122.6-204.6 ha, respectively. Male and female weasels showed similar trends in their use of birch, shrub, aspen, and jack pine habitats but differed in their use of other habitats. Male weasels preferred habitats associated with high abundance of red squirrels (black spruce and larch) and under-utilized habitats associated with low abundance of red squirrels (3-year-old regenerating aspen cutblocks). Female weasels showed the opposite trend. They preferred habitats associated with high abundance of voles (3- year-old regenerating aspen cutblocks) and under-utilized black spruce and larch habitats. Weasels used a variety of rest sites and most of these sites were associated with their prey. Squirrel middens and the bases of trees or snags were the most common rest sites used by male weasels. Most rest sites used by female weasels were in residual logging material. In cutblocks, female weasels preferentially used areas with slash. Abundant small mammals, in particular C. gapperi, appeared to be a factor promoting the use of slash by females. To ensure suitable habitat is provided for male weasels, forest managers should retain patches of coniferous trees that are old enough to produce cones. These patches support red squirrels that are prey to male weasels and whose middens are their preferred resting sites. Forest managers should retain forest stands (undisturbed by timber harvesting) adjacent to 3-year-old regenerating aspen cutblocks to ensure occupation of by females. The retention of logging slash in these cutblocks had high densities of red-backed voles and also provided rest sites for females.

description: Цель – оценить клиническую эффективность переливания тромбоцитного концентрата, полученного методом афереза, для больных гематологического, онкологического и хирургического профиля в условиях Окружной клинической больницы города Ханты-Мансийска. Проведена оценка клинической эффективности переливания у больных (n = 50) гематологического, онкологического и хирургического профиля тромбоцитного концентрата, полученного методом афереза. Показано, что тромбоцитаферез значимо не влияет на гематологические показатели крови донора. Получено, что надежным методом определения эффективности трансфузии является определение скорректированного прироста тромбоцитов через 24 часа после окончания переливания тромбоконцентрата. Выявлено, что потеря количества тромбоцитов в крови доноров после цитафереза составляет 33 %. У больных онкогематологического, кардиологического или хирургического профиля переливание тромбоцитного концентрата в среднем составляло 460 × 109 клеток в объеме 314 мл. Скорректированный прирост тромбоцитов через 24 часа после процедуры в среднем составил 17,8 × 109/л при микроскопическом методе оценки и 14,4 × 109/л при подсчете на гематологическом анализаторе.
description: The aim of the study is to evaluate the clinical efficacy of platelet concentrates transfusion for patients with a hematological, oncological and surgical profile in the District Clinical Hospital of Khanty-Mansiysk. The evaluation of the clinical efficacy of platelet concentrates transfusion obtained by the method of apheresis in patients (n = 50) is carried out. It is shown that thrombocytapheresis does not significantly affect the hematological parameters of the blood of the donor. It is found that a reliable method for determining the efficiency of transfusion is to determine the corrected platelet growth 24 hours after the end of the platelet transfusion. It is revealed that the loss of platelet count in the blood of donors after cytapheresis is 33 %. In patients with an onco-hematological, cardiac or surgical profile, platelet transfusion consists of 460 × 109 cells in 314 ml. The corrected platelet count 24 hours after the procedure is 17.8 × 109/l with a microscopical evaluation method and 14.4 × 109/l when measured on a hematology analyzer.

description: As in the agri-food business supply chain networks are evolving in our paper we want to elaborate on managerial questions regarding them. In this context our first aim is to advance the concept of chain management by introducing a more differentiated view. Since many articles highlight the pivotal role of communication the second aim of our paper refers to the role of communication for the management of supply chain networks. Because the agri-food business is still dominated by small and medium-sized enterprises our third aim is to apply our thoughts of chain management on small and medium-sized enterprises.

description: Entropy production is a key concept of thermodynamics and allows one to analyze the operation of engines. For the Scovil-Schulz-DuBois heat engine, the archetypal three-level thermal maser coupled to thermal baths, it was argued that the common definition of heat flow may provide negative entropy production for certain parameters [E. Boukobza and D. J. Tannor, Phys. Rev. Lett. 98, 240601 (2007)]. Here, we show that this can be cured, if corrections for detuning are properly applied to the energies used for the bath transitions. This method can be used more generally for the thermodynamical analysis of optical transitions where the modes of the light field are detuned from the transition energy.

Molecular Disks in the Elliptical Galaxies NGC 83 and NGC 2320

description: The molecular gas in (some) early type galaxies holds important clues to the history and the future of these galaxies. In pursuit of these clues we have used the BIMA millimeter array to map CO emission in the giant elliptical galaxies NGC 83 and NGC 2320 and to search for CO emission from the S0 galaxy NGC 5838. We also present V and R images of NGC 83 and NGC 2320 which trace their dust distributions and enable a search for disky stellar structures. The molecular gas in NGC 83 is well relaxed, but both CO and dust in NGC 2320 show asymmetric structures which may be linked to a recent acquisition of the gas. However, the specific angular momentum distribution of molecular gas in NGC 2320 is consistent with that of the stars. Internal origin of the gas (stellar mass loss) cannot, therefore, be ruled out on angular momentum grounds alone. We also consider the evidence for star formation activity and disk growth in these two elliptical galaxies. Radio continuum and FIR fluxes of NGCv83 suggest star formation activity. NGC 2320 has bright [O III] emission, but its large radio/FIR flux ratio and the mismatch between the kinematics of CO and [O III] suggest that the ionized gas should not be attributed to star formation. The origin and future of these two CO-rich early type galaxies are thus complex, multi-faceted stories.

description: We study complex integrable systems on quiver varieties associated with the cyclic quiver, and prove their superintegrability by explicitly constructing first integrals. We interpret them as rational Calogero-Moser systems endowed with internal degrees of freedom called spins. They encompass the usual systems in type $A_{n-1}$ and $B_n$, as well as generalisations introduced by Chalykh and Silantyev in connection with the multicomponent KP hierarchy. We also prove that superintegrability is preserved when a harmonic oscillator potential is added.

description: Understanding the finite-size corrections to the fundamental excitations of a theory is the first step towards completely solving for the spectrum in finite volume. We compute the leading exponential correction to the quantum energy of the fundamental excitation of the light-cone gauged string in AdS(5) x S(5), which is the giant magnon solution. We present two independent ways to obtain this correction: the first approach makes use of the algebraic curve description of the giant magnon. The second relies on the purely field-theoretical Luscher formulas, which depend on the world-sheet S-matrix. We demonstrate the agreement to all orders in g/Delta of these approaches, which in particular presents a further test of the S-matrix. We comment on generalizations of this method of computation to other string configurations.

description: Two thirds of Kenyan cut flowers are marketed through Dutch flower auctions, while the remainder is marketed directly to retailers. Auctions do not restrict the volumes marketed; however price determination is based on a spot market. A Transaction Cost approach is used to investigate the differences in marketing costs between the channels. The results suggest that there are no differences between the channels in terms of uncertainty about prices, finding buyers or transparency of quality standards. Auction growers pay a higher marketing fee but they have significantly fewer office employees and flower varieties compared to growers who market directly.

Оценены результаты лечения 72 пациентов с острой кишечной непроходимостью (43 и 29 пациентов со спаечной и обтурационной кишечной непроходимостью). С целью оценки органных и системных нарушений измеряли интраабдоминальное давление непрямым методом по методике Kron и соавт. [1] с размещением ≪открытого≫ катетера в мочевом пузыре. Также проведены экспериментальные исследования – у 10 кроликов породы шиншилла моделировали II ст. интраабдоминальной гипертензии и морфологически исследовали ткани тонкого кишечника и почек. У пациентов с абдоминальным давлением выше нормы развиваются нарушение водного баланса, гипопротеинемия, гипоонкия, воспаление. В морфологическом субстрате тонкого кишечника и почек выявлены повреждение энтероцитов, нарушение микроциркуляции, признаки воспаления.
description: The aim of the study is to determine the pathogenesis and clinical manifestations of intra-abdominal hypertension in patients with acute intestinal obstruction for optimization of surgical treatment approaches. The treatment results of 72 patients with acute intestinal obstruction (43 and 29 patients with adhesive and obturational intestinal obstruction) are evaluated. In order to assess organ and systemic disturbances, intra-abdominal pressure is measured by an indirect method according to the procedure of Kron et al. [1] with the placement of an “open” catheter in the bladder. Experimental studies are also conducted. The II st. intra-abdominal hypertension is modeled and tissues of the small intestine and kidneys are morphologically examined in 10 rabbits of the Chinchilla breed. In patients with elevated abdominal pressure above the norm, a fluid imbalance, hypoproteinemia, reduction in oncotic pressure and inflammation develop. The anatomical substrate of the small intestine and the kidneys revealed damage to the enterocytes, impaired microcirculation, signs of inflammation.

description: A conditioned stochastic process can display a very different behavior from the unconditioned process. In particular, a conditioned process can exhibit non-Gaussian fluctuations even if the unconditioned process is Gaussian. In this work, we revisit the Ferrari-Spohn model of a Brownian bridge conditioned to avoid a moving wall, which pushes the system into a large-deviation regime. We extend this model to an arbitrary number $N$ of non-crossing Brownian bridges. We obtain the joint distribution of the distances of the Brownian particles from the wall at an intermediate time in the form of the determinant of an $N\times N$ matrix whose entries are given in terms of the Airy function. We show that this distribution coincides with that of the positions of $N$ spinless noninteracting fermions trapped by a linear potential with a hard wall. We then explore the $N \gg 1$ behavior of the system. For simplicity we focus on the case where the wall's position is given by a semicircle as a function of time, but we expect our results to be valid for any concave wall function.

description: Except for few studies, not many have analyzed the significance of embeddedness and networks for consumers coping with uncertainty. In our explorative study based on focus groups in Norway and Germany, consumers' attitudes to purchasing of seafood are further explored. We find that fish in various contexts is conceived as spooky, which signifies its credence attributes. According to a conversational analysis, we find that consumers classify seafood along various dimensions associated with both health risk and sensory quality. Most salient is the distinction between fresh fish and frozen fish. Whereas frozen fish very seldom entails notions of risk, purchasing of fresh fish evokes scepticism and uncertainty. We discuss strategies among consumers for coping with uncertainty, and find that consumers discern between various types of outlets in order to attain predictability. There is a strong belief in the superiority of the cold chain and industrial standards among supermarkets and discounters for granting quality of frozen fish, while these trust factors do not count for fresh fish. Instead consumers attend certain speciality shops that are selected either by own trials and errors or from information mediated through embedded networks.

description: We demonstrate that the combination of GALEX UV photometry in the FUV (~1530 angstroms) and NUV (~2310 angstroms) passbands with optical photometry in the standard U,B,V,R,I filters can efficiently break the age-metallicity degeneracy. We estimate well-constrained ages, metallicities and their associated errors for 42 GCs in M31, and show that the full set of FUV,NUV,U,B,V,R,I photometry produces age estimates that are ~90 percent more constrained and metallicity estimates that are ~60 percent more constrained than those produced by using optical filters alone. The quality of the age constraints is comparable or marginally better than those achieved using a large number of spectrscopic indices.

description: IGR J19140+0951 was discovered by INTEGRAL in 2003 in the 4-100 keV band. Observations with INTEGRAL and RXTE provide a tentative identification as a high-mass X-ray binary (HMXB) with a neutron star as accretor. However, an optical counterpart was thus far not established, nor was the presence of a pulsar which is commonly observed in HMXBs. We observed IGR J19140+0951 with Chandra and find the source to be active at a similar flux as previous measurements. The lightcurve shows a marginally significant oscillation at 6.5 ks which requires confirmation. We determine a sub-arcsecond position from the Chandra data and identify the heavily reddened optical counterpart 2MASS 19140422+0952577 in the 2MASS catalog. Optical follow-up observations with the William Herschel Telescope at La Palma exhibit a continuum spectrum coming out of extinction above 7000 Angstrom without strong absorption or emission features. V, I and Ks band photometry point to an optical counterpart extincted by A[V]=11+/-2. The extinction is consistent with the interstellar value. None of the data reject the suspicion that IGR J19140+0951 is an HMXB with additional circumstellar obscuration around the accretor.

description: We performed an internal-consistency test of the KiDS+VIKING-450 (KV450) cosmic shear analysis with a colour-based split of source galaxies. Utilising the same measurements and calibrations for both sub-samples, we inspected the characteristics of the shear measurements and the performance of the calibration pipelines. On the modelling side, we examined the observational nuisance parameters, specifically those for the redshift calibration and intrinsic alignments, using a Bayesian analysis with dedicated test parameters. We verified that the current nuisance parameters are sufficient for the KV450 data to capture residual systematics, with slight deviations seen in the second and the third redshift tomographic bins. Our test also showcases the degeneracy between the inferred amplitude of intrinsic alignments and the redshift uncertainties in low redshift tomographic bins. The test is rather insensitive to the background cosmology and, therefore, can be implemented before any cosmological inference is made.

description: Several studies have so far investigated transport properties of strongly correlated systems. Interesting features of these materials are the lack of resistivity saturation well beyond the Mott-Ioffe-Regel limit and the scaling of the resistivity with the hole density in underdoped cuprates. Due to the strongly correlated nature of these materials, mainly numerical techniques have been employed. A key role in this regards is thought to be played by the continuous transfer of spectral weight from coherent to incoherent states. In this paper we employ a simple analytical expression for the electronic Green's function to evaluate both quasi-particle and transport properties in correlated systems. Our analytical approach permits to enlighten the specific role of the spectral transfer due to the correlation on different features. In particular we investigate the dependence of both quasi-particle and transport scattering rate on the correlation degree and the criterion for resistivity saturation. systems.

description: Product recalls have become an almost familiar phenomenon in a consumer's daily life. The reasons for this include the increasingly advanced and at the same time vulnerable technology of consumer products and the emergent law of strict liability of manufacturers and dealers in the US and Europe. This paper deals with the seller's choice situation. The seller has more or less vague evidence of potential damages which could possibly be related to the use or misuse of his products, altogether indicators of a potential product-related crisis. In such a situation, the seller must decide whether to initiate an immediate product recall or to continue with business as usual, whereas the second option may involve a recall at a later date. The analysis of the choice situation is a preliminary one. The academic literature concerning recall behavior is rather sparse. The first part of the paper, therefore, merely collects and discusses some of the relevant factors pro and contra product recalls, as mentioned in various reports and case analyses. The result is a system of factors, such as evidence of damage and of a liability risk, efficiency and speed of a recall, and the availability of other measures, e.g. warnings, the relative importance of the product (substitutes in sight?), significant and minor influence of relevant media, the seller's reputation and ability, the willingness of consumers to cooperate, etc. The second part of the paper takes a closer look at two of the previously mentioned factors: the seller's reputation and the time span between gathering initial evidence of a crisis and the recall. Both factors have already been empirically analyzed before. The findings, hitherto, are based on US data and do not seem to fit to our analysis of variance, which is based on a representative German sample of consumers. After this international comparison there will be a brief outlook containing remarks on managerial implications.

description: We introduce an agent-based model for the spreading of technological developments in socio-economic systems where the technology is mainly used for the collaboration/interaction of agents. Agents use products of different technologies to collaborate with each other which induce costs proportional to the difference of technological levels. Additional costs arise when technologies of different providers are used. Agents can adopt technologies and providers of their interacting partners in order to reduce their costs leading to microscopic rearrangements of the system. Analytical calculations and computer simulations revealed that starting from a random configuration of different technological levels a complex time evolution emerges where the spreading of advanced technologies and the overall technological progress of the system are determined by the amount of advantages more advanced technologies provide, and by the structure of the social environment of agents. We show that agents tend to form clusters of identical technological level with a power law size distribution. When technological progress arises, the spreading of technologies in the system can be described by extreme order statistics.

description: We consider a class of models in which the neutrinos acquire Majorana masses through mixing with singlet neutrinos that emerge as composite states of a strongly coupled hidden sector. In this framework, the light neutrinos are partially composite particles that obtain their masses through the inverse seesaw mechanism. We focus on the scenario in which the strong dynamics is approximately conformal in the ultraviolet, and the compositeness scale lies at or below the weak scale. The small parameters in the Lagrangian necessary to realize the observed neutrino masses can naturally arise as a consequence of the scaling dimensions of operators in the conformal field theory. We show that this class of models has interesting implications for a wide variety of experiments, including colliders and beam dumps, searches for lepton flavor violation and neutrinoless double beta decay, and cosmological observations. At colliders and beam dumps, this scenario can give rise to striking signals involving multiple displaced vertices. The exchange of hidden sector states can lead to observable rates for flavor violating processes such as $μ\rightarrow e γ$ and $μ\rightarrow e$ conversion. If the compositeness scale lies at or below a hundred MeV, the rate for neutrinoless double beta decay is suppressed by form factors and may be reduced by an order of magnitude or more. The late decays of relic singlet neutrinos can give rise to spectral distortions in the cosmic microwave background that are large enough to be observed in future experiments.

description: We investigate the laws of thermodynamics in an accelerating universe driven by dark energy with a time-dependent equation of state. In the case we consider that the physically relevant part of the Universe is that envelopped by the dynamical apparent horizon, we have shown that both the first law and second law of thermodynamics are satisfied. On the other hand, if the boundary of the Universe is considered to be the cosmological event horizon the thermodynamical description based on the definitions of boundary entropy and temperature breaks down. No parameter redefinition can rescue the thermodynamics laws from such a fate, rendering the cosmological event horizon unphysical from the point of view of the laws of thermodynamics.

description: Problématique : En Suisse, un pays où l’alcool est un bien culturel et économique, les adolescents et les jeunes adultes sont rapidement confrontés à la consommation d’alcool. Ces consommations comportent des risques à long terme et des risques à court terme. L’alcool peut être utilisé pour diminuer le stress, la pression et plus généralement pour faire face aux problèmes psychosociaux. L’utilisation de l’alcool comme coping est très négatif et engendre plus de risques de développer des problèmes de consommation. Question : Les interventions infirmières en milieu scolaire post-obligatoire sont-elles adéquates pour pallier aux consommations d’alcool, dues au stress, liées aux réussites sociales et à la pression des pairs, des adolescents et des jeunes adultes ? Méthode : Six articles ont été sélectionnés dans les bases de données CINHAL. Nous avons utilisé des descripteurs tels que « Jeune adulte », « Consommation d’alcool », « Stress », « Rôle infirmier ». Ces articles ont été sélectionnés à l’aide de différents critères d’inclusion et d’exclusion. Résultats : La gestion du stress est prioritaire afin de diminuer les problèmes liés à l’alcool. L'infirmière peut amener des techniques d’intervention. Elle peut également jouer un rôle de prévention et de dépistage en lien avec les consommations. Conclusion : Le rôle des infirmières dans cette démarche de préventions primaire et secondaire est nécessaire afin de promouvoir l’adoption de coping favorable à une transition en santé. L’aide à l’apprentissage de la gestion des émotions, comme le stress, s'avère essentielle.

description: In the past five years, there has been a conspicuous increase in the number of integrated part-farm irrigation schemes in the Upper Darling Region of New South Wales. The main characteristics of 26 such schemes are described in this article. Evidence remains of a number of older irrigation installations along the Darling River. Some suggestions are made about the reasons why these earlier schemes failed. These are - (a) Failure of returns to justify the cash and opportunity costs, (b) Increasing labour costs, (c) Erratic water supply, (d) The effects of occasional, severe flooding, and (e) Agronomic problems. Several of these factors are still operative, and may cause difficulties with the present schemes.
The French Plan - Blueprint for World Trade Without Tears?

Subjects: International Relations/Trade

description: The French Plan proposes a series of international commodity agreements providing for price discrimination between economically advanced and backward countries. It was developed initially as a consequence of the particular set of price support measures adopted in the E.E.C.'s Common Agricultural Policy, but, after: extension and modification, has been put forward as offering a solution to various problems of international trade in agricultural commodities including disposal of agricultural surpluses, the reconciliation of divergent interests in the United Kingdom's accession to the Common Market and the difficulties of underdeveloped countries arising from declining terms of trade and limited export opportunities for primary products. It must, however, also be viewed as an attempt to stave off the need for agricultural adjustment within the European Community and to provide common price levels for food in the Common Market's competitor countries. There are some weaknesses in the conception of the Plan and its practicability is suspect at several points. The Plan could tend to substitute aid through food supplies for other possibly more useful forms of economic aid to underdeveloped countries. Moreover, it would have far reaching implications for efficiency of resource allocation in that it would introduce a wholly managed system of international trade in foodstuffs. Despite its superficial appeal it is therefore concluded that the Plan does not offer a workable solution to the problems of stagnating world trade in agriculture, aggravated as they will be by the Common Market's commitment to a rigid form and high level of agricultural protection.

description: We identify a parametrically light dilaton by studying the perturbations of metastable vacua along a branch of regular supergravity backgrounds that are dual to four-dimensional confining field theories. The branch includes also stable and unstable solutions. The former encompass, as a special case, the geometry proposed by Witten as a holographic model of confinement. The latter approach a supersymmetric solution, by enhancing a condensate in the dual field theory. A phase transition separates the space of stable backgrounds from the metastable ones. In proximity of the phase transition, one of the lightest scalar states inherits some of the properties of the dilaton, despite not being particularly light.

description: I am suggesting that the term 'basket weaving' be replaced with the term 'woven-fiber technology' when talking about baskets and fiber constructions in prehistory. I say this because the term 'basket weaving' may be outdated. While it once may have been a general term for all kinds of weaving that resulted in a wide variety of products, most people today think of it as meaning baskets only. Furthermore, while basket weaving was a technology and baskets could be thought of as tools and basketry was clearly an industry, none of these words are associated with Paleolithic or Neolithic basket weaving (see Google searches) although all these terms are used when discussing or researching stone tools from those periods. In the discipline of paleoanthropology, this becomes a serious problem as it tends to limit the scope of research and funding for research. I suggest that the term basket weaving should be replaced with a more inclusive term that also emphasizes that the weaving of fibers was a technology and an important one that may have begun early in the development of hominins. The term I suggest is 'woven-fiber technology'.
The Comparative Profitability of Fat Lamb Raising and Wool Production in the Glen Innes District

description: The long, cold winters and the summer rainfall of the New England region mean that, in the absence of conservation of surplus summer grass, wool-cutting properties tend to be overstocked in the winter and understocked in the summer. The closing up of relatively frost-resistant improved pasture in the autumn for later grazing in the winter does help, however, to level out that pasture production which is consumable on the hoof. Even so, the existence of improved pastures capable of rearing milk-fed, fat lambs has inclined many graziers towards running their properties, all or in part, under fat lamb rearing systems. As they see it, this simplifies management problems relating to stock numbers. The size of the ewe flock is solely determined by the number of ewes which it is considered a place can carry through the winter. If, as is usual, cross-bred ewes are used and the replacements are bought-in there is scope for easy adjustment of flock numbers to accord with the current seasonal conditions. The lambs reared by these ewes are drafted off the place before the onset of winter, having been fattened on the luxuriant growth of summer grass. Thus, the humps in pasture production and in animal numbers
Hodge structures of CM-type

description: We show that any effective Hodge structure of CM-type occurs (without having to take a Tate twist) in the cohomology of some CM abelian variety over C. As a consequence we get a simple proof of the theorem (due to Hazama) that the usual Hodge conjecture for the class of all CM abelian varieties implies the general Hodge conjecture for the same class.

description: Recurrent Neural Networks (RNN) received a vast amount of attention last decade. Recently, the architectures of Recurrent AutoEncoders (RAE) found many applications in practice. RAE can extract the semantically valuable information, called context that represents a latent space useful for further processing. Nevertheless, recurrent autoencoders are hard to train, and the training process takes much time. In this paper, we propose an autoencoder architecture with sequence-aware encoding, which employs 1D convolutional layer to improve its performance in terms of model training time. We prove that the recurrent autoencoder with sequence-aware encoding outperforms a standard RAE in terms of training speed in most cases. The preliminary results show that the proposed solution dominates over the standard RAE, and the training process is order of magnitude faster.

SARS-CoV-2 vaccination
United States

description: BACKGROUND: Worsening of anxiety and depressive symptoms have been widely described during the COVID-19 pandemic. It can be hypothesized that vaccination could link to reduced symptoms of anxiety and/or depression. However, to date, no study has assessed this. This study aims to examine anxiety and depressive symptoms after vaccination in US adults, meanwhile test sociodemographic disparities in these outcomes. METHODS: Data from the January 6-June 7 2021, cross-sectional Household Pulse Survey were analyzed. Using survey-weighted logistic regression, we assessed the relationships between SARS-CoV-2 vaccination and anxiety and/or depressive symptoms, both on overall and sociodemographic subgroups. We controlled for a variety of potential socioeconomic and demographic confounding factors. RESULTS: Of the 453,167 participants studied, 52.2% of the participants had received the COVID-19 vaccine, and 26.5% and 20.3% of the participants reported anxiety and depression, respectively. Compared to those not vaccinated, the vaccinated participants had a 13% lower odds of anxiety (adjusted odds ratio [AOR] = 0.85, 95%CI 0.83-0.90) and 17% lower odds of depression (AOR = 0.83, 95%CI 0.79-0.85). Disparities on the above associations were identified in age, marital status, education level, ethnic/race, and income level, but not on gender. LIMITATIONS: The causal inference was not able to be investigated due to the cross-sectional study design. CONCLUSION: Being vaccinated for SARS-CoV-2 was associated with lower odds of anxiety and/or depressive symptoms. While those more middle-aged or more affluent, were more likely to show these negative associations, the contrary was observed in ethnic minorities and those with lower educational attainment. More strategic and demography-sensitive public health communications could perhaps temper these issues.
