description: Die im Epidemiologischen Bulletin 2/2021 veröffentlichte Empfehlung tritt in Kraft, sobald ein erster Impfstoff zum Schutz vor COVID-19 zugelassen und in Deutschland verfügbar ist. Aufgrund begrenzter Impfstoffverfügbarkeit soll die Impfung zunächst nur Personengruppen angeboten werden, die ein besonders hohes Risiko für schwere oder tödliche Verläufe einer COVID-19-Erkrankung haben oder die beruflich entweder besonders exponiert sind oder engen Kontakt zu vulnerablen Personengruppen haben. Diese STIKO-Empfehlung setzt sich aus der allgemeinen Impfempfehlung und einer Empfehlung zur Priorisierung zusammen. Die Priorisierungsempfehlung hat nur solange Gültigkeit, bis genügend Impfstoff verfügbar ist. Mittelfristig ist es das Ziel, allen Menschen einen gleichberechtigten Zugang zu einer Impfung gegen COVID-19 anbieten zu können.
Consumption, Land Prices and the Monetary Transmission Mechanism in Japan

description: Economic theory suggests circumstances in which a rise in short term real interest rates can increase consumption, contrary to much conventional wisdom. This paper suggests that these circumstances are more likely to be prevalent in Japan and finds strong empirical evidence for a positive effect. Life-cycle theory also suggests that housing wealth effects on aggregate consumption including imputed rent are small and negative. Positive effects of the kind found in the UK and the US are due to the role of the credit channel. In countries where consumer access to credit is restricted, these restrictions can enhance the negative effect on consumption of higher house prices because saving for a housing deposit needs to be higher. Our evidence of a negative land price effect for Japan supports this hypothesis. We find no evidence of significant household credit market liberalization from a model for household debt in Japan.

description: We present a search for a new particle T' decaying to a top quark via T' -> t + X, where X goes undetected. We use a data sample corresponding to 5.7 fb-1 of integrated luminosity of ppbar collisions with sqrt{s} = 1.96 TeV, collected at Fermilab by the CDF II detector. Our search for pair production of T' is focused on the hadronic decay channel, ppbar -> T'T' -> tt +XX -> bbqqqq + XX. We interpret our results in terms of a model where T' is an exotic fourth generation quark and X is a dark matter candidate. The data are consistent with standard model expectations. We set a limit on the generic production of T'T'->tt+XX, excluding the fourth generation exotic quarks T' at 95% confidence level up to m_T' = 400 GeV/c2 for m_X < 70 GeV/c2.
Effect of surfactants on asphaltene interfacial films and stability of water-in-oil emulsions

description: Undesirable water-in-oil emulsions often form during oil processes. Chemical treatment is a common method for breaking down these emulsions; however, this technique is not always effective. In order to improve the chemical treatment of emulsions, it is useful to have an understanding of emulsion stability. The stability of water-in-oil emulsions depends in part on the surface properties. The surface is composed of natural material present in the produced oil, such as asphaltenes, resins, clays and surfactants, which adsorb on the water-oil interface. Asphaltenes play an important role in stabilizing the emulsion since they irreversibly adsorb at the interface of the water droplets and form a steric barrier or rigid skin that prevents coalescence. An effective demulsifier must disrupt this film in order to accelerate coalescence. However, the chemical treatment design is still done by trial and error partly because the effect of surfactants on interfacial films is poorly understood. This thesis focuses on emulsions stabilized by asphaltene films. It was previously found that the stability of these emulsions could be predicted from both the compressibility and crumpling film ratio of irreversibly adsorbed asphaltene films. In this study, the effect of surfactants on asphaltene interfacial films is analyzed through the change in film properties. Surface pressure isotherms were measured at 23 °C for model interfaces between aqueous surfactant solutions and asphaltenes dissolved in toluene and heptane:toluene mixtures. Compressibility, crumpling film ratio and surface pressure were determined from the surface pressure isothe1ms. The stability of water-in-oil emulsions was determined for the same systems based on the free water resolved after repeated treatment involving heating at 60°C and centrifugation. Experimental variables included concentration of asphaltenes (5 and 10 kg/m³), concentration and type of surfactant (Aerosol OT, nonylphenol ethoxylates, dodecylbenzene sulfonic acids, sodium naphthenate) and aging time (from 10 min to 4 h). The effect of surfactants on film properties and emulsion stability was found to divide in two distinct behaviours. 1) surfactants that fom1ed reversible films and destabilized emulsions and 2) surfactants that maintained the irreversible adsorption at the interface and could enhance emulsion stability.

description: This PhD thesis is divided into two sections. The first section is comprised of a reflective essay (of approximately 20,000 words) that seeks to explore the process of creative practice which culminated in the second section, a collection of forty-four poems titled Ark Shell. The reflective essay aims to explore the manner in which poetry can interact with and draw inspiration from archives; these archives come in many forms including physical ruins, the UK census archive, the BBC archive and family archives (both documentary and anecdotal). It also investigates the link between poetic sequences and timelines, extrapolating from this to discuss ‘collection as sequence’. Finally, it questions the manner in which a poem or poetry collection itself can give a ‘second life’ to forgotten or marginalised archival material. The collection of poems themselves contains two short narrative sequences and two miscellanies. These miscellanies in turn contain sequences and groupings of their own which I have consciously curated and encouraged.
After Maastricht: Public Investment, Economic Integration, and International Capital Mobility

Year: 1993
Subjects: Economics

description: This paper studies some interesting implications of economic integration in the context of a neoclassical model of international trade, optimal public investment, and capital mobility. Due the endogeneity of the productive public capital stock, international capital mobility, while equalizing returns to capital, can lead to a divergence in the wages earned by labor. We also demonstrate that international capital mobility can set off an "infrastructure" investment boom. If the benefits of public capital spill over across national borders, governments in the Nash equilibrium spend the "1992" dividend on an excessive provision of public services, attempting to free ride on the public capital of their neighbors.

Notes on the Political Economy of Nationalism
Creators: name: Findlay, Ronald E.
Publisher: name: Columbia University
Year: 1992
Subjects: Economics

description: "The resurgence of nationalism all over the world in the last few years can be said to arise, in every case, from a lack of congruence between "state" and "nation." While each of these terms is highly complex and controversial, we all know the main difference between them. The state is a political and administrative unit, claiming the "monopoly of the legitimate use of force" over all the inhabitants of a given territory. The nation, on the other hand, is an "imagined community," including the dead and the unborn, who are bound together by the ties of kinship, language, custom and shared myths that separate it from other similar collectivities.-7 Thus we can have a nation without a state, as in the case of the Kurds, or states that comprise many nations, such as the former USSR and Yugoslavia, and a nation divided between several states, as in the case of the Italians and Germans before unification in the nineteenth century, or the two Germanys and two Koreas of more recent history."

description: This paper discusses the benefits and risks that financial globalization entails for developing countries. Financial globalization can lead to large benefits, particularly to the development of the financial system. But financial globalization can also come with crises and contagion. The net effect of financial globalization is likely positive in the long run, with risks being more prevalent right after countries liberalize. So far, only some countries, sectors, and firms have taken advantage of globalization. As financial systems turn global, governments lose policy instruments, so there is an increasing scope for some form of international financial policy cooperation.

description: This study presents a procedure developed to measure the liquid-deposit interface temperature during solids deposition from wax- solvent mixtures under static and sheared cooling conditions using a novel batch deposition apparatus. Batch deposition experiments were carried out with two types of multi-component waxes, using different wax concentrations, coolant temperatures, and different size of cooling surface area. All experiments showed the interface temperature throughout the deposit layer growth process was equal to the wax appearance temperature (WA T) of the liquid phase. Results from static cooling deposition experiments compared well with predictions from a mathematical model based on the moving boundary problem formulation. In addition, precipitation-filtration experiments were developed and performed on several wax solvent mixtures at temperatures below the respective WAT. The WAT of all filtrates was found to be 1-2°C less than the precipitation and filtration temperature. A novel bench-scale flow-loop apparatus was developed to investigate the role of heat transfer during deposition from wax solvent mixtures under 'cold flow' conditions. Experiments were carried out with 3 and 6 mass% wax-solvent mixtures, at different mixture flow rates, coolant temperature, and mixture temperature. The deposit mass increased with a decrease in the coolant temperature and an increase in both the wax concentration and mixture temperature. Solids deposition during 'cold flow' did not occur when the difference between the liquid-deposit interface temperature became equal to the coolant temperature. Predictions from a steady-state heat-transfer model showed good agreement with the 'cold flow' deposition experimental data.

description: Bibliography: p. 187-196
description: Singing is usually an enjoyable activity but not to those who have labeled themselves as non-singers. Through the use of narrative inquiry, this study examines the phenomenon of the adult non-singer in Canadian society. The researcher's teaching experience involving adult non-singers and the dearth of academic research prompted an interest in this topic. Two research questions were proposed: 1) why are there adults who have designated themselves as non-singers? 2) is it possible for this label to be reversed through a positive singing experience? Twelve participants, including men and women of different ethnic background and age, participated in eight sessions. The participants were initially asked various questions about their childhood singing experiences and their personal views on singing. The remainder of the sessions was spent in vocal production. The sessions were transcribed and, along with related literature, spoke to the issues in the research questions. The research, through the participants' narratives, offered three reasons as to why there are adults who designate as non-singers: 1) the encountering of a negative childhood experience with singing at school; 2) the encountering of a negative childhood experience with singing at home; 3) the acceptance of a normative concept of singer. The research found that the possibility of reversing the label of non-singer through a positive singing experience was inconclusive. The majority of the participants in the study changed their perception of self as non-singer to self as singer. Nevertheless, a minority of participants continued to view themselves as non-singers despite the positive experience with singing. Implications for music educators were drawn from the themes of the participants' narratives as a conclusion to the study. These themes included awareness of the: 1) impact of negative encounters on students; 2) effect of cultural assumptions on the classroom; 3) understanding that students are at different points on the musical spectrum; 4) need to support non-singers in the education system.

description: Determining the interaction partners among protein/domain families poses hard computational problems, in particular in the presence of paralogous proteins. Available approaches aim to identify interaction partners among protein/domain families through maximizing the similarity between trimmed versions of their phylogenetic trees. Since maximization of any natural similarity score is computationally difficult, many approaches employ heuristics to maximize the distance matrices corresponding to the tree topologies in question. In this paper we devise an efficient deterministic algorithm which directly maximizes the similarity between two leaf labeled trees with edge lengths, obtaining a score-optimal alignment of the two trees in question. Our algorithm is significantly faster than those methods based on distance matrix comparison: 1 minute on a single processor vs. 730 hours on a supercomputer. Furthermore we have advantages over the current state-of-the-art heuristic search approach in terms of precision as well as a recently suggested overall performance measure for mirrortree approaches, while incurring only acceptable losses in recall. A C implementation of the method demonstrated in this paper is available at http://compbio.cs.sfu.ca/mirrort.htm

Introduction Countries with high maternal and newborn mortality can benefit from national facility level data that describe intra-facility emergency referral patterns for major obstetric complications. This paper assesses the relationship between referral and facilities’ readiness to treat complications at each level of the health system in Ghana. We also investigate other facility characteristics associated with referral. Methods The National Emergency Obstetric and Newborn Care Assessment 2010 provided aggregated information from 977 health facilities. Readiness was defined in a 2-step process: availability of a health worker who could provide life-saving interventions and a minimum package of drugs, supplies, and equipment to perform the interventions. The second step mapped interventions to major obstetric complications. We used descriptive statistics and simple linear regression. Results Lower level facilities were likely to refer nearly all women with complications. District hospitals resolved almost two-thirds of all complicated cases, referring 9%. The most prevalent indications for referral were prolonged/obstructed labor and antepartum hemorrhage. Readiness to treat a complication was correlated with a reduction in referral for all complications except uterine rupture. Facility readiness was low: roughly 40% of hospitals and 10% of lower level facilities met the readiness threshold. Facilities referred fewer women when they had higher caseloads, more midwives, better infrastructure, and systems of communication and transport. Discussion Understanding how deliveries and obstetric complications are distributed across the health system helps policy makers contextualize decisions about the pathways to providing maternity services. Improving conditions for referral (by increasing access to communication and transport systems) and the management of obstetric complications (increasing readiness) will enhance quality of care and make referral more effective and efficient.

description: Using the notion of an elementary loop, Gebser and Schaub (2005. Proceedings of the Eighth International Conference on Logic Programming and Nonmonotonic Reasoning (LPNMR’05 ), 53–65) refined the theorem on loop formulas attributable to Lin and Zhao (2004) by considering loop formulas of elementary loops only. In this paper, we reformulate the definition of an elementary loop, extend it to disjunctive programs, and study several properties of elementary loops, including how maximal elementary loops are related to minimal unfounded sets. The results provide useful insights into the stable model semantics in terms of elementary loops. For a nondisjunctive program, using a graph-theoretic characterization of an elementary loop, we show that the problem of recognizing an elementary loop is tractable. On the other hand, we also show that the corresponding problem is coNP-complete for a disjunctive program. Based on the notion of an elementary loop, we present the class of Head-Elementary-loop-Free (HEF) programs, which strictly generalizes the class of Head-Cycle-Free (HCF) programs attributable to Ben-Eliyahu and Dechter (1994. Annals of Mathematics and Artificial Intelligence 12, 53–87). Like an HCF program, an HEF program can be turned into an equivalent nondisjunctive program in polynomial time by shifting head atoms into the body.

Characterization of constitutive caspase-6 deficient mice : insights into axonal degeneration, excitotoxicity and age dependent behavioral and neuroanatomical changes
Creators: name: Uribe Laisequilla, Valeria
Publisher: name: University of British Columbia
Year: 2012

description: Apoptosis or programmed cell death is a cellular pathway involved in normal cell turnover, developmental tissue remodeling, embryonic development, cellular homeostasis maintenance and chemical-induced cell death. Caspases are a family of intracellular cysteine-aspartic proteases that play a key role in programmed cell death. Aside from their roles during development, aberrant activation of caspases has been implicated in several human diseases. In particular, numerous findings implicate Caspase-6 (Casp6) in neurodegenerative diseases highlighting the need for a deeper understanding of Casp6 biology and its role in brain development. The use of targeted caspase deficient mice has been instrumental for studying the involvement of caspases in apoptosis. The goal of this study was to perform an in depth neuropathological and behavioral characterization of constitutive Casp6-deficient (Casp6 -/-) mice in order to understand the physiological function of Casp6 in brain development, structure and function and to establish if any biological effects are caused by ablation of Casp6. We demonstrate that Casp6 -/- neurons are protected against NMDAmediated excitotoxicity and NGF-deprivation induced axonal degeneration. Furthermore, Casp6 deficient mice show an age-dependent increase in cortical and striatal volume. In addition, these mice show a hypoactive phenotype and display learning deficits. The age-dependent behavioral and region-specific neuroanatomical changes observed in the Casp6 -/- mice suggest that Casp6 deficiency has a more pronounced effect in brain regions that are involved in neurodegenerative diseases, such as the striatum in Huntington disease and the cortex in Alzheimer Disease. These results provide further insights into the role of Casp6 in neurodegenerative diseases.

description: The response surface methodology (RSM) was used to optimize the exopolysaccharide (EPS) production by a lactic acid bacteria (LAB) Weissella confusa XG-3. Two-level factorial design screened three significantly influencing factors sucrose, initial pH and sodium acetate. Central composite design (CCD) predicted under the condition of sucrose 80.1 g L−1, initial pH 5.8 and sodium acetate 3.7 g L−1, the maximal EPS yield obtained a 2.9-fold increase, reaching 97.5 ± 1.1 g L−1. This maximal value was far exceeding EPS production by other W. confusa species strains reported so far. The results suggested that W. confusa XG-3 had a potential for large-scale EPS production. The rheological properties of XG-3 EPS was further investigated. It was a typical non-Newtonian fluid, exhibiting pseudo-plastic behavior. The EPS concentration and temperature exerted positive and negative impact on apparent viscosity, respectively. The XG-3 EPS maintained relatively higher viscosity at moderate pH (6–8). The intrinsic viscosity [η] was 409.7 (25 °C) and 201.7 (35 °C), which was relevant to temperature but irrelevant to EPS concentration. This EPS efficiently coagulated sucrose-supplemented milk in a concentration-dependent manner. These results indicated that XG-3 EPS had an applicable potential in food processing fields especially dairy products.

description: Garcilaso de la Vega el Inca, for several centuries doubtlessly the most discussed and most eminent writer of Andean America in the 16th and 17th centuries, throughout his life set the utmost value on the fact that he descended matrilineally from Atahualpa Yupanqui and from the last Inca emperor, Huayna Capac. Thus, both in his person and in his creative work he combined different cultural worlds in a polylogical way. (1) Two painters boasted that very same Inca descent - they were the last two great masters of the Cuzco school of painting, which over several generations of artists had been an institution of excellent renown and prestige, and whose economic downfall and artistic marginalization was vividly described by the French traveller Paul Mancoy in 1837.(2) While, during the 18th century, Cuzco school paintings were still much cherished and sought after, by the beginning of the following century the elite of Lima regarded them as behind the times and provincial, committed to an 'indigenous' painting style. The artists from up-country - such was the reproach - could not keep up with the modern forms of seeing and creating, as exemplified by European paragons. Yet, just how 'provincial', truly, was this art?

description: This research uses a quasi-experimental design to evaluate the impact of Project Safe Neighborhood (PSN) initiatives on neighborhood level crime rates in Chicago. Four interventions are analyzed: (1) increased federal prosecutions for convicted felons carrying or using guns, (2) the length of sentences associated with federal prosecutions, (3) supply-side firearm policing activities, and (4) social marketing of deterrence and social norms messages through justice-style offender notification meetings. Using an individual growth curve models and propensity scores to adjust for non-random group assignment, our findings suggest that several PSN interventions are associated with greater declines of homicide in the treatment neighborhoods as compared to the control neighborhoods. The largest effect is associated with the offender notification meetings that stress individual deterrence, normative change in offender behavior, and increasing views on legitimacy and procedural justice. Possible competing hypotheses and directions for individual-level analysis are also discussed.

Hexagonal Boron Carbon Nitrogen (h-BCN) is also investigated due the increased interest shown by the research community towards this material. In particular, the Deformation Potentials are computed by means of Density Functional Theory (DFT), while the carrier mobility is obtained according to the Takagi model (S. Takagi, A. Toriumi, and H. Tango, IEEE Trans. Electr. Dev. 41, 2363 (1994)). We will show that graphene with a reduced degree of hydrogenation can compete, in terms of mobility, with silicon technology.

Creators: name: Marc, Odin

Publisher: name: Universität Potsdam
Year: 2019

description: We present an analytical, seismologically consistent expression for the surface area of the region within which most landslides triggered by an earthquake are located (landslide distribution area). This expression is based on scaling laws relating seismic moment, source depth, and focal mechanism with ground shaking and fault rupture length and assumes a globally constant threshold of acceleration for onset of systematic mass wasting. The seismological assumptions are identical to those recently used to propose a seismologically consistent expression for the total volume and area of landslides triggered by an earthquake. To test the accuracy of the model we gathered geophysical information and estimates of the landslide distribution area for 83 earthquakes. To reduce uncertainties and inconsistencies in the estimation of the landslide distribution area, we propose an objective definition based on the shortest distance from the seismic wave emission line containing 95% of the total landslide area. Without any empirical calibration the model explains 56% of the variance in our dataset, and predicts 35 to 49 out of 83 cases within a factor of 2, depending on how we account for uncertainties on the seismic source depth. For most cases with comprehensive landslide inventories we show that our prediction compares well with the smallest region around the fault containing 95% of the total landslide area. Aspects ignored by the model that could explain the residuals include local variations of the threshold of acceleration and processes modulating the surface ground shaking, such as the distribution of seismic energy release on the fault plane, the dynamic stress drop, and rupture directivity. Nevertheless, its simplicity and first-order accuracy suggest that the model can yield plausible and useful estimates of the landslide distribution area in near-real time, with earthquake parameters issued by standard detection routines.

description: We review the facts pertaining to some recent antimonopoly cases in Japan involving interference with unauthorized imports, so-called parallel imports, and propose economic explanations for the behavior of the foreign manufacturers in these cases. The intellectual property law of Japan provides a mechanism for private obstruction of parallel imports but under the antimonopoly law of Japan as implemented by the Japan Fair Trade Commission such obstruction is per se illegal. To the extent that price discrimination is the rationale for obstruction of parallel imports the JFTC policy has promoted lower prices and increased economic welfare in Japan. But we argue that in several of the cases we examine the rationale for obstructing parallel imports was to preserve incentives for distributors to invest and innovate and to preserve efficient marketing arrangements that depended upon resale price maintenance.

description: In this work, a novel sodium-fluorescent crystal (Na-FS) was synthesized from 4-dimethylaminobenzoic acid and sodium hydroxide by one-pot hydrothermal method. The structure and conformation of Na-FS were conﬁrmed by single-crystal X-ray diﬀraction and scanning electron microscope, and the optical properties were studied by fluorescence spectrometer. The results showed that: Na-FS was a triclinic crystal, space group was P-1, cell parameters a, b and c were 10.5113(3), 15. 9198(5) and 15.9560(5) Å, and the number of independent atoms Z in a structure cell was 2, respectively. Additionally, Na-FS has a blue fluorescence emission (around 360 nm under excited at the range of 230–300 nm) with great photostability and photobleaching resistance, and the quantum yield of Na-FS is 30.58%.

description: To reach the goals of the Global Hepatitis Elimination 2030 program, Indonesia is now preparing a new regulation for hepatitis B vaccinations for adult population. This study aimed to determine the factors influencing vaccine uptake for hepatitis B in the adult population, and identify barriers to, and facilitators of, hepatitis B vaccination programmes. An explanatory sequential mixed methods design was implemented in this study. We conducted a survey involving 893 participants in the general population followed by 14 in-depth interviews with health providers. The survey found that only 15% (95% confidence interval 13–18%) of participants received at least one dose of the hepatitis B vaccine. Factors associated with vaccine uptake were, living in Yogyakarta compared to living in Aceh, having secondary and higher education compared to primary education, working as a health worker compared to working in other sectors, and having health insurance that covered hepatitis B vaccination compared to not having such health insurance. Our qualitative study also identified several barriers to the adult hepatitis B vaccination programme in Indonesia such as the high cost of vaccination, lack of vaccine availability in certain areas, limited human resources to implement the hepatitis B vaccination programme, and the ineffective dissemination of hepatitis B vaccination. This study highlights that accessibility and affordability of vaccinations are important determinants of vaccination uptake that should be taken into account when planning vaccination campaigns.

description: Tracking changes in biodiversity through time requires an understanding of the relationship between modern diversity and how this diversity is preserved in the fossil record. Fossil pollen is one way in which past vegetation diversity can be reconstructed. However, there is limited understanding of modern pollen-vegetation diversity relationships from biodiverse tropical ecosystems. Here, pollen (palynological) richness and diversity (Hill N (1)) are compared with vegetation richness and diversity from forest and savannah ecosystems in the New World and Old World tropics (Neotropics and Palaeotropics). Modern pollen data were obtained from artificial pollen traps deployed in 1-ha vegetation study plots from which vegetation inventories had been completed in Bolivia and Ghana. Pollen counts were obtained from 15 to 22 traps per plot, and aggregated pollen sums for each plot were > 2,500. The palynological richness/diversity values from the Neotropics were moist evergreen forest = 86/6.8, semi-deciduous dry forest = 111/21.9, wooded savannah = 138/31.5, and from the Palaeotropics wet evergreen forest = 144/28.3, semi-deciduous moist forest = 104/4.4, forest-savannah transition = 121/14.1; the corresponding vegetation richness/diversity was 100/36.7, 80/38.7 and 71/39.4 (Neotropics), and 101/54.8, 87/45.5 and 71/34.5 (Palaeotropics). No consistent relationship was found between palynological richness/diversity, and plot vegetation richness/diversity, due to the differential influence of other factors such as landscape diversity, pollination strategy, and pollen source area. Palynological richness exceeded vegetation richness, while pollen diversity was lower than vegetation diversity. The relatively high global diversity of tropical vegetation was found to be reflected in the pollen rain.

description: A random variable Z will be called self-inverse if it has the same distribution as its reciprocal 1/Z. It is shown that if Z is defined as a ratio, X/Y, of two rv's X and Y (with Pr[X=0]=Pr[Y=0]=0), then Z is self-inverse if and only if X and Y are (or can be chosen to be) exchangeable. In general, however, there may not exist iid X and Y in the ratio representation of Z.

description: Honey bees are essential for crop and wild plant pollination. However, many countries have reported high annual colony losses caused by multiple possible stressors. Diseases, particularly those caused by viruses, are a major cause of colony losses. However, little is known about the prevalence of honey bee pathogens, particularly virus prevalence, in Egyptian honey bees. To address this shortfall, we determined the prevalence of widespread bee viruses in honey bee colonies in Egypt—whether it is affected by geography, the season, or infestation with Varroa destructor (varroa) mites. Honey bee worker samples were collected from 18 geographical regions across Egypt during two seasons: winter and summer of 2021. Three apiaries were chosen in each region, and a pooled sample of 150 worker bees was collected from five colonies in each apiary then screened by qPCR for 10 viral targets: acute bee paralysis virus (ABPV), black queen cell virus (BQCV), chronic bee paralysis virus (CBPV), deformed wing virus (DWV) genotypes A (DWV-A), B (DWV-B) and D (Egyptian bee virus), Israeli acute paralysis virus (IAPV), Kashmir bee virus (KBV), sacbrood virus (SBV), and slow bee paralysis virus (SBPV). Our results revealed that DWV-A was the most prevalent virus, followed by BQCV and ABPV; the DWV genotype now spreading across the world, DWV-B, was not detected. There was no difference in varroa infestation rates as well as virus prevalence between winter and summer. However, colonies infected with BQCV had a significantly higher varroa count (adjusted p < 0.05) in the winter season, indicating that there is a seasonal association between the intensity of infestation by varroa and the presence of this virus. We provide data on the current virus prevalence in Egypt, which could assist in the protection of Egypt’s beekeeping industry. Moreover, our study aids in the systematic assessment of the global honey bee virome by filling a knowledge gap about the prevalence of honey bee viruses in Egypt.

description: Dust extinction and reddening are ubiquitous in astronomical observations and are often a major source of systematic uncertainty. We present here a study of the correlation between extinction in the Milky Way and the equivalent width of the NaI D absorption doublet. Our sample includes more than 100 high resolution spectra from the KECK telescopes and nearly a million low resolution spectra from the Sloan Digital Sky Survey (SDSS). We measure the correlation to unprecedented precision, constrain its shape, and derive an empirical relation between these quantities with a dispersion of order 0.15 magnitude in E(B-V). From the shape of the curve of growth we further show that a typical sight line through the Galaxy, as seen within the SDSS footprint, crosses about three dust clouds. We provide a brief guide on how to best estimate extinction to extragalactic sources such as supernovae, using the NaI D absorption feature, under a variety of circumstances.

description: It is unclear whether bufotenin (= N,N-dimethyl-serotonin = 5-hydroxy-N,N-dimethyl-tryptamine), a hallucinogenic drug, can act on human cardiac serotonin 5-HT4 receptors. Therefore, the aim of the study was to examine the cardiac effects of bufotenin and for comparison tryptamine in transgenic mice that only express the human 5-HT4 receptor in cardiomyocytes (5-HT4-TG), in their wild-type littermates (WT) and in isolated electrically driven (1 Hz) human atrial preparations. In 5-HT4-TG, we found that both bufotenin and tryptamine enhanced the force of contraction in left atrial preparations (pD2 = 6.77 or 5.5, respectively) and the beating rate in spontaneously beating right atrial preparations (pD2 = 7.04 or 5.86, respectively). Bufotenin (1 µM) increased left ventricular force of contraction and beating rate in Langendorff perfused hearts from 5-HT4-TG, whereas it was inactive in hearts from WT animals, as was tryptamine. The positive inotropic and chronotropic effects of bufotenin and tryptamine were potentiated by an inhibitor of monoamine oxidases (50 µM pargyline). Furthermore, bufotenin concentration- (0.1–10 µM) and time-dependently elevated force of contraction in isolated electrically stimulated musculi pectinati from the human atrium and these effects were likewise reversed by tropisetron (10 µM). We found that bufotenin (10 µM) increased the phosphorylation state of phospholamban in the isolated perfused hearts, left and right atrial muscle strips of 5-HT4-TG but not from WT and in isolated human right atrial preparations. In summary, we showed that bufotenin can increase the force of contraction via stimulation of human 5-HT4 receptors transgenic mouse cardiac preparations but notably also in human atrial preparations.
