description: RR Lyrae stars may be the best practical tracers of Galactic halo (sub-)structure and kinematics. The PanSTARRS1 (PS1) $3π$ survey offers multi-band, multi-epoch, precise photometry across much of the sky, but a robust identification of RR Lyrae stars in this data set poses a challenge, given PS1's sparse, asynchronous multi-band light curves ($\lesssim 12$ epochs in each of five bands, taken over a 4.5-year period). We present a novel template fitting technique that uses well-defined and physically motivated multi-band light curves of RR Lyrae stars, and demonstrate that we get accurate period estimates, precise to 2~sec in $>80\%$ of cases. We augment these light curve fits with other {\em features} from photometric time-series and provide them to progressively more detailed machine-learned classification models. From these models we are able to select the widest ($3/4$ of the sky) and deepest (reaching 120 kpc) sample of RR Lyrae stars to date. The PS1 sample of $\sim 45,000$ RRab stars is pure (90\%), and complete (80\% at 80 kpc) at high galactic latitudes. It also provides distances precise to 3\%, measured with newly derived period-luminosity relations for optical/near-infrared PS1 bands. With the addition of proper motions from {\em Gaia} and radial velocity measurements from multi-object spectroscopic surveys, we expect the PS1 sample of RR Lyrae stars to become the premier source for studying the structure, kinematics, and the gravitational potential of the Galactic halo. The techniques presented in this study should translate well to other sparse, multi-band data sets, such as those produced by the Dark Energy Survey and the upcoming Large Synoptic Survey Telescope Galactic plane sub-survey.

description: Achieving optimal clinical responses and minimizing side effects through precision dosing of antipsychotics in children and adolescents with psychiatric disorders remains a challenge. Identifying patient characteristics (covariates) that affect pharmacokinetics can inform more effective dosing strategies and ultimately improve patient outcomes. This review aims to provide greater insight into the impact of covariates on the clinical pharmacokinetics of antipsychotics in pediatric populations. A comprehensive literature search was conducted, and the main findings regarding the effects of the covariates on the pharmacokinetics of antipsychotics in children and adolescents are presented. Our study highlights significant covariates, including age, sex, weight, CYP2D6 phenotype, co-medication, and smoking habits, that affect the pharmacokinetics of antipsychotics. However, the findings were generally limited by the small sample sizes of naturalistic, open-label, observational studies and the homogeneous subgroups. Dosing based on weight and preemptive genotyping could prove beneficial for optimizing the dosing regimen in pediatric populations. Future research is needed to refine dosing recommendations and establish therapeutic reference ranges critical for precision dosing and Therapeutic Drug Monitoring (TDM). The integration of individual patient characteristics with TDM can further optimize the efficacy and safety of antipsychotics for each patient.

description: A space is called linearly H-closed iff any chain cover possesses a dense member. This property lies strictly between feeble compactness and H-closedness. While regular H-closed spaces are compact, there are linearly H-closed spaces which are even collectionwise normal and Fréchet-Urysohn. We give examples in other classes, and ask whether there is a first countable normal linearly H-closed non-compact space in ZFC. We show that PFA implies a negative answer if the space is moreover either locally separable or locally compact and locally ccc. Ostaszewski space (built with $\diamondsuit$) is an example which is even perfectly normal. We also investigate Menger-like properties for the class of od-covers, that is, covers whose members are open and dense.

description: Intermittent computing systems undergo frequent power failure, hindering necessary data sample capture or timely on-device computation. These missing samples and deadlines limit the potential usage of intermittent computing systems in many time-sensitive and fault-tolerant applications. However, a group/swarm of intermittent nodes may amalgamate to sense and process all the samples by taking turns in waking up and extending their collective on-time. However, coordinating a swarm of intermittent computing nodes requires frequent and power-hungry communication, often infeasible with limited energy. Though previous works have shown promises when all intermittent nodes have access to the same amount of energy to harvest, work has yet to be looked into scenarios when the available energy distribution is different for each node. The proposed AICS framework provides an amalgamated intermittent computing system where each node schedules its wake-up schedules based on the duty cycle without communication overhead. We propose one offline tailored duty cycle selection method (Prime-Co-Prime), which schedules wake-up and sleep cycles for each node based on the measured energy to harvest for each node and the prior knowledge or estimation regarding the relative energy distribution. However, when the energy is variable, the problem is formulated as a Decentralized-Partially Observable Markov Decision Process (Dec-POMDP). Each node uses a group of heuristics to solve the Dec-POMDP and schedule its wake-up cycle.

description: Stadiums that are solely used for athletic competitions can lead to a desolate post-event environment and the waste of resources. However, China still lacks systematic research on the integration models of and paths between stadiums and commercial spaces. This study identified models of stadium and commercial space integration, analyzed the associated factors, and proposed a development framework. The research methods included literature review, case data collection, pattern induction and expert interviews. By analyzing 58 cases, this study summarized eight models for stadium–commercial space integration; analyzed the correlation between different models and development types, land use environments, and business configurations; and conducted in-depth analysis of two cases. The findings indicate that an open mindset during the development stage can promote the emergence of new models, utilizing the land environment during the design stage can improve stadium utilization rate, and a multi-business configuration during the operation stage can promote the formation of urban vitality. A development framework is proposed, which emphasizes the collaboration of all stakeholders to optimize every step of the decision-making, construction and operation processes. These findings contribute to identifying development directions for stadiums in China and provide practical methods for the transformation of stadiums into dynamic urban complexes.

description: Objectives: ANCA-associated vasculitis (AAV) patients under immunosuppressive therapy are at high risk of having a severe COVID-19 infection. At the same time, they are also less likely to develop a sufficient immune response after vaccinations. We therefore examined the antibody response over time in patients with AAV after complete vaccination against COVID-19. Methods: In this monocentric observational cohort study, we enrolled 52 AAV patients (28 men and 24 women) (PR3-ANCA n=31, MPO-ANCA n=19, ANCA-negative n=2). Patients were tested for antibody response during routine follow-up visits up to 33 weeks after complete vaccination. SARS-CoV-2 spike antibody testing was performed with chemiluminescence immunoassays designed to detect antibodies against the SARS-CoV-2 spike protein (Elecsys Anti-SARS-CoV-2 S, Roche Diagnostics, Mannheim, Germany) in the Institute of Laboratory Medicine of the University Hospital Munich. According to the manufacturer’s specifications, anti-SARS-CoV-2 S titres >0.8 U/mL are considered reactive (sensitivity 98.8% and specificity 99.9%). Anti-SARS-CoV-2 S titres <300 U/mL were defined as low antibody response. Results: 49 patients completed a series of two SARS-CoV-2 vaccinations. Three patients were infected with COVID-19 and subsequently received only one vaccination according to national recommendations. After complete vaccination, 41 patients (79%) developed a detectable anti-SARS-CoV-2 spike antibody response, with 14 patients (34%) showing low antibody response (<300 U/L). 11 patients (21%) remained without an antibody response. After having received the vaccination, 22 patients underwent immunosuppressive therapy with Rituximab. Humoral response declined continuously during follow-up of up to 6 months (see figure 1). Rituximab treatment after vaccination resulted in substantial antibody decline. Four patients at present have received a booster, all of which demonstrate a significant antibody increase. Conclusions: In our cohort, the majority of patients fortunately developed a detectable SARS-CoV-2 spike antibody titre after vaccination, although patients receiving Rituximab showed a diminished response. The observed decline in titres matches other studies‘ results and concerns for an increasing susceptibility to COVID-19 infection. Our preliminary data suggests a positive impact of booster vaccination also in AAV patients. Disclosures: MF – Advisory Board/Study participation (Chemocentryx/Vifor; Alexion; Ablynx/Vifor; Alnylam).

Pedestrians rotation measurement in bidirectional streams

description: This study presents an experimental measurement of pedestrians' body rotation in bidirectional streams. A mock-up corridor monitored using a camera placed on azimuthal position is used to study pedestrians' behavior in unidirectional and bidirectional flows. Additionally, a commercial tablet is fixed on the chest of sample pedestrians to examine their body rotation (or yawing) which cannot be obtained using position tracking alone. Angular velocity is recorded and simultaneously stored in a central location using a wireless network, thus allowing the analysis of body movements with a high sampling rate and a limited delay. To investigate the influence of major/minor flow proportion (flow-ratio) on bidirectional streams two different situations were tested: the balanced configuration (with equal flows in both directions) and an unbalanced configuration (with different major and minor flow). Results clearly show that unidirectional flow is more stable compared to the bidirectional case, requiring less time to cross the experimental section and showing a very small amount of rotation during the whole experiment. Both bidirectional configurations showed high values of body rotation, in particular during lane formation and dissolution. Finally, rotation directly measured on pedestrians' body was compared with the one obtained indirectly by analyzing pedestrians' trajectories. The comparison shows that, at least from a qualitative point of view, both methods are in agreement, thus suggesting that even properties which can only be measured by motion sensing could be obtained indirectly through the analysis of trajectories. Concluding, it has been suggested that while lanes help smooth out bidirectional flows, larger instabilities are observed compared to the unidirectional case. Lane separation and/or appropriate guidance are therefore required.

description: Pyrrolidines type 2,4-disubstituted (alkyl, aryl or heteroaryl)-6,8-dioxo-3,7-diazabicyclo [3.3.0] octanes (8a-d) were successfully synthesized by an efficient one pot 1,3-dipolar cycloaddition of azomethine ylides (in situ generated from the reaction of aromatic aldehydes and methyl ester of alpha-amino acids) with dipolarophile (N-phenylmaleimide). The reaction of compounds 8a-d with hydrazine in ethanol at room temperature took place under nucleophilic substitution which furnished 5-amino-4,6-dioxo-octahydropyrrolo [3,4-b] pyrrole-3-carboxylic acid phenylamides (12a-d). Structures of the products were confirmed by IR and 1H NMR. The compounds (8b and 12a) were evaluated for antimicrobial (agar dilution method) and antioxidative (DPPH; 2,2-diphenyl-1-picrylhydrazyl and SOD; superoxide dismutase assays) activities. The results showed that at concentrations of 4-256 µg/mL, the tested compounds exhibited non-significant antimicrobial growth, whereas the 12a at 200 µg/mL began to exert some antioxidative activity.

description: Research on posttraumatic growth (PTG) has been marred by the ubiquity of retrospective perceived growth assessments that lack construct validity. However, one justification for assessing perceived growth is that such perceptions may be a catalyst for subsequent change. We examined this question using a measurement burst design in a representative midlife sample who had experienced a major negative life event in the past year (Wave 1 N of participants = 804). Participants completed three waves of retrospective measures of perceived growth (Posttraumatic Growth Inventory); current-standing measures of PTG domains; and experience sampling assessments of state manifestations of growth-relevant domains twice a day for three weeks (N of assessments = 32,099) over six months. In random intercept cross-lagged panel models, perceived growth did not predict subsequent observed change in current standing or aggregated state assessments of growth. Overall, perceived growth does not appear to serve as a catalyst for positive change in the short-term.

description: Objectives: The emergence of strains of SARS-CoV-2 exhibiting increase viral fitness and immune escape potential, such as the Delta variant (B.1.617.2), raises concerns in immunocompromised patients. We aimed to evaluate seroconversion, cross-neutralization and T-cell responses induced by BNT162b2 in immunocompromised patients with systemic inflammatory diseases. Methods: Prospective monocentric study including patients with systemic inflammatory diseases and healthcare immunocompetent workers as controls. Primary end points were anti-spike antibodies levels and cross-neutralization of Alpha and Delta variants after BNT162b2 vaccine. Secondary end points were T-cell responses, breakthrough infections and safety. Results: Sixty-four cases and 21 controls not previously infected with SARS-CoV-2 were analyzed. Kinetics of anti-spike IgG after BNT162b2 vaccine showed lower and delayed induction in cases, more pronounced with rituximab. Administration of two doses of BNT162b2 generated a neutralizing response against Alpha and Delta in 100% of controls, while sera from only one of rituximab-treated patients neutralized Alpha (5%) and none Delta. Other therapeutic regimens induced a partial neutralizing activity against Alpha, even lower against Delta. All controls and cases except those treated with methotrexate mounted a SARS-CoV-2 specific T-cell response. Methotrexate abrogated T-cell responses after one dose and dramatically impaired T-cell responses after 2 doses of BNT162b2. Third dose of vaccine improved immunogenicity in patients with low responses. Conclusions: Rituximab and methotrexate differentially impact the immunogenicity of BNT162b2, by impairing B-cell and T-cell responses, respectively. Delta fully escapes the humoral response of individuals treated with rituximab. These findings support efforts to improve BNT162b2 immunogenicity in immunocompromised individuals (ClinicalTrials.gov number, NCT04870411). Disclosures: None

description: The teaching of modern physics often uses the history of physics as a didactic tool. However, as in this process the history of physics is not something studied but used, there is a danger that the history itself will be distorted in, as Butterfield calls it, a "Whiggish" way, when the present becomes the measure of the past. It is not surprising that reading today a paper written more than a hundred years ago, we can extract much more of it than was actually thought or dreamed by the author himself. We demonstrate this Whiggish approach on the example of Woldemar Voigt's 1887 paper. From the modern perspective, it may appear that this paper opens a way to both the special relativity and to its anisotropic Finslerian generalization which came into the focus only recently, in relation with the Cohen and Glashow's very special relativity proposal. With a little imagination, one can connect Voigt's paper to the notorious Einstein-Poincare priority dispute, which we believe is a Whiggish late time artifact. We use the related historical circumstances to give a broader view on special relativity, than it is usually anticipated.

description: Over the past decade a large family of spintronic devices have been proposed as candidates for replacing CMOS for future digital logic circuits. Using the recently developed Modular Approach framework, we investigate and identify the physical bottlenecks and engineering challenges facing current spintronic devices. We then evaluate how systematic advancements in material properties and device design innovations impact the performance of spintronic devices, as a possible continuation of Moore's Law, even though some of these projections are speculative and may require technological breakthroughs. Lastly, we illustrate the use of the Modular Approach as an exploratory tool for probabilistic networks, using superparamagnetic magnets as building blocks for such networks. These building blocks leverage the inherent physics of stochastic spin-torque switching and could provide ultra-compact and efficient hardware for beyond-Boolean computational paradigms.

Evaluating Ethiopia's Agricultural Export Potential: Empirical Evidence Using Gravity Model
Creators: name: Amare, Alemaye
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Both theories and evidences indicates that the large share of Ethiopia's export is mainly primary/agricultural products. Owing to this fact, this study attempted to empirically figure out what determines the agricultural export trend of Ethiopia with 38 major trading partners over the study period, 1995-2015. The augmented dynamic gravity model has been estimated using system GMM technique where the log form agricultural export of Ethiopia to the major trading partners is the dependent variable. The coefficients obtained are then used to predict the agricultural export trade potentials for Ethiopia. The empirical result revealed that application of dynamic gravity models is likely to produce consistent results where the lagged agricultural export has a positive and statistically significant effect on current agricultural export flows. Apart from this, other traditional gravity model variables such as Ethiopia's population and home country's trade openness are found to have positive and significant impact towards agricultural export of Ethiopia. Importing country's population, distance and home country's contract intensive money variables as well were found to be significant in affecting Ethiopia's agricultural export negatively. As far as agricultural export potential is concerned, European countries remained to be the dominant future potential destinations of Ethiopia's agricultural export. Specifically, agricultural export potential to countries including Israel, Switzerland, Greece, Norway, Finland, Sweden, Romania and Austria are not yet exploited. This implies that export promotion towards these economies has to be prioritized through bilateral trade agreement arrangements and reduction in public sector bottlenecks to exporters.
Extension of the General Thermal Field Equation for nanosized emitters

description: During the previous decade, K.L. Jensen et. al. developed a general analytical model that successfully describes electron emission from metals both in the field and thermionic regimes, as well as in the transition region. In that development, the standard image corrected triangular potential barrier was used. This barrier model is valid only for planar surfaces and therefore cannot be used in general for modern nanometric emitters. In a recent publication the authors showed that the standard Fowler-Nordheim theory can be generalized for highly curved emitters if a quadratic term is included to the potential model. In this paper we extend this generalization for high temperatures and include both the thermal and intermediate regimes. This is achieved by applying the general method developed by Jensen to the quadratic barrier model of our previous publication. We obtain results that are in good agreement with fully numerical calculations for radii $R>4nm$, while our calculated current density differs by a factor up to 27 from the one predicted by the Jensen's standard General-Thermal-Field (GTF) equation. Our extended GTF equation has application to modern sharp electron sources, beam simulation models and vacuum breakdown theory.

description: Was ist ein multifunktionaler Arbeitsplatz und was wünschen die Benutzer einer Bibliothek an ihnen zur Verfügung gestellten Arbeitsplätzen vorzufinden? Mit diesen zwei zentralen Fragen beschäftigte sich die Universitätsbibliothek Hohenheim eingehend. Der Benutzer = Kunde ist König. Er stellt sich vor, ein Maximum an Information aus der Bibliothek mitzunehmen. Wie kann eine Bibliothek diesem Bedürfnis Rechnung tragen? Zunächst einmal ist zu klären, welche Art von Information vom Benutzer gewünscht wird und wie diese Information optimal aufbereitet sein sollte. Das von der UB Hohenheim gefundene Lösungskonzept besteht darin, an einem PC alle zur Zeit möglichen elektronischen Bibliotheksangebote anzubieten. In der Praxis bedeutet das, alles von Email bis OPAC, von WWW bis CD-ROM, von Windowsanwendungen bis Hosts in die Angebotspalette eines Arbeitsplatzes einzubinden. Die grafische Oberfläche ermöglicht es dem Benutzer, parallel in verschiedenen Anwendungen zu arbeiten. Trotz weitgehend vorausgesetzter Selbständigkeit der Benutzer stehen die Auskunft gebenden Bibliothekare vor der Anforderung, alle Anwendungen selbst bedienen zu können. Dazu ist ein umfangreicher Know How Transfer zwischen EDV-Leuten und Bibliothekaren erforderlich. Dies wird erreicht durch Schulungen, Arbeitskreise und insbesondere durch neue Strukturen innerhalb der Bibliothek. Ein multifunktionaler Benutzerarbeitsplatz stellt die "Bibliothek auf den Kopf" und den Benutzer auf den Boden der heutigen Informationsvielfalt.

Basidiospores 9.5–11.8 × 5.7–6.7 μm, broadly ellipsoid, lacking lateral bulges, smooth, hyaline, inamyloid, thin-walled. Basidia all 2-sterigmate, clamped. Basidioles clavate. Hymenial cystidia common on sides and edges of lamellae, 48–56 × 9–17.5 μm, ventricose with wall up to 0.8 μm thick (metuloids); apex smooth or capped with resinous incrustations; central axis smooth, hyaline. Pileipellis a thin Rameales -structure of diverticulate hyphae. Pileus trama of loosely interwoven hyphae 2–4 μm diam., hyaline, inamyloid, non-incrusted, clamped, embedded in a thick gelatinous matrix.
 Status: The thick-walled, non-diverticulate hymenial cystidia in combination with ellipsoid (non-tetrahedral) basidiospores, the absence of a stipe, and strongly gelatinized tramal tissues indicate placement in Campanella. It should be noted that the holotype specimen has only 2-spored basidia. This makes the newly described variety C. simulans var. bispora Manimohn & Leelavathy superfluous.

description: I will be reporting on the results of a language survey done in April 2022 in five Mbugwe villages, which aimed to investigate pronunciation differences for certain groups of words. Previous research concluded that there are not significant enough differences to identify separate Mbugwe dialects. The survey in April 2022 supports this finding, nevertheless, there are differences in how people speak and this research seeks to describe these differences with a view to proposing a spelling system which will be acceptable to all Mbugwe speakers.

Geometry in Active Learning for Binary and Multi-class Image Segmentation

description: We propose an active learning approach to image segmentation that exploits geometric priors to speed up and streamline the annotation process. It can be applied for both background-foreground and multi-class segmentation tasks in 2D images and 3D image volumes. Our approach combines geometric smoothness priors in the image space with more traditional uncertainty measures to estimate which pixels or voxels are the most informative, and thus should to be annotated next. For multi-class settings, we additionally introduce two novel criteria for uncertainty. In the 3D case, we use the resulting uncertainty measure to select voxels lying on a planar patch, which makes batch annotation much more convenient for the end user compared to the setting where voxels are randomly distributed in a volume. The planar patch is found using a branch-and-bound algorithm that looks for a 2D patch in a 3D volume where the most informative instances are located. We evaluate our approach on Electron Microscopy and Magnetic Resonance image volumes, as well as on regular images of horses and faces. We demonstrate a substantial performance increase over other approaches thanks to the use of geometric priors.

On The Problem of Splitting Deformations of Super Riemann Surfaces

description: An odd deformation of a super Riemann surface $\mathcal S$ is a deformation of $\mathcal S$ by variables of odd parity. In this article we study the obstruction theory of these odd deformations $\mathcal X$ of $\mathcal S$. We view $\mathcal X$ here as a complex supermanifold in its own right. Our objective in this article is to show, when $\mathcal X$ is a deformation of second order of $\mathcal S$ with genus $g>1$: if the primary obstruction class to splitting $\mathcal X$ vanishes, then $\mathcal X$ is in fact split. This result leads naturally to a conjectural characterisation of odd deformations of $\mathcal S$ of any order.
