Coxiella burnetii in Dogs and Cats from Portugal: Serological and Molecular Analysis

Dogs and cats are potential sources of infection for some zoonotic diseases such as Q fever, caused by Coxiella burnetii, a multiple host pathogen. Q fever outbreaks in dogs and cats have been related with parturition and abortion events, and ticks have a potential role in the transmission of this pathogen. This study aimed to screen for C. burnetii in dogs and cats, and in ticks collected from infested animals. An observational descriptive study was conducted in Portugal at two time points nine years apart, 2012 and 2021. Sera obtained from dogs and cats (total n = 294) were tested for C. burnetii antibodies using a commercial ELISA adapted for multi-species detection. C. burnetii DNA was screened by qPCR assay targeting IS1111 in uterine samples and in ticks. A decrease in the exposure to C. burnetii was observed in cats from 17.2% (95% CI: 5.8–35.8%) in 2012 to 0.0% in 2021, and in dogs from 12.6% (95% CI: 7.7–19.0%) in 2012 to 1.7% (95% CI: 0.3–9.1%) in 2021 (p < 0.05). Overall, and despite differences in the samples, rural habitat seems to favour the exposure to C. burnetii. The DNA of C. burnetii was not detected in ticks. The low seropositivity observed in 2021 and the absence of C. burnetii DNA in the tested samples, suggest that dogs and cats from Portugal are not often exposed to the pathogen. Nevertheless, the monitoring of C. burnetii infection in companion animals is an important tool to prevent human outbreaks, considering the zoonotic potential for owners and veterinarians contacting infected animals, mainly dogs and cats from rural areas which often come into contact with livestock.
High figure of merit in partially filled ytterbium skutterudite materials

We present evidence of a relatively high dimensionless figure of merit (ZT) in a polycrystalline skutterudite partially filled with ytterbium ions. The small-diameter yet heavy-mass Yb atoms partially filling the voids of the host CoSb3 system exhibit low values of thermal conductivity while the quite favorable electronic properties are not substantially perturbed by the addition of Yb. This combination is ideal for thermoelectric applications exemplifying the “phonon-glass electron-crystal” concept of a thermoelectric material, resulting in ZT=0.3 at room temperature and ZT∼1 at 600 K for Yb0.19Co4Sb12.
Diagnosis of pulmonary edema by a surgically noninvasive microwave technique

A method for measuring content of water in the lung is described. The method utilizes changes in the amplitude and phase of the microwave signal transmitted through the thorax. The phase of the transmission coefficient is particularly sensitive and provides a means of detecting and monitoring of pulmonary edema. Theoretical predictions of sensitivity were confirmed experimentally in agar models of the thorax. The optimal frequency lies between 740 MHz and 1.5 GHz. A 50-ohm open-transmission line was designed and used to couple 915-MHz energy into tissues with minimal external radiation. Other advantages of this strip-line concept include its low mass, small size, and flat configuration, which render it utile for clinical purposes. The feasibility of the method was also evaluated in experiments on dogs. In a typical dog experiment, the phase of the microwave-transmitted signal changed by an average value of 2° for each 10 milliliters of infused blood. These results provide strong encouragement that incipient pulmonary edema can be detected before clinical emergencies arise, thus providing the physician a safe and sensitive tool for diagnosis of pulmonary function.
Strain control of magnetism in graphene decorated by transition-metal atoms

We report a strain-controlled tuning of magnetism in transition-metal-atom-decorated graphene. Our first-principles calculations demonstrate that strain can lead to a sudden change in the magnetic configuration of a transition metal (TM) adatom and the local atomic structure in the surrounding graphene layer, which have a dramatic effect on the effective exchange coupling between neighboring TM atoms. A strong spin-dependent hybridization between TM d and graphene � orbital states, derived from the orbital selection rule of the local lattice symmetry, is responsible for the determination of the local electronic and magnetic structure. Our results indicate that the strain can be an effective way to control the magnetism of atomic-scale nanostructures, where the reliable control of their magnetic states is a key step for the future spintronic applications.
Dynamics Changes of Solids Gastric Emptying Post -Pancreaticoduodenectomy

BACKGROUND: Gastric emptying (GE) is one of the common post-operative complications after pancreaticoduodenectomy (PD). Multiple factors have been involved in this complication. Dynamic studies such as GE scintigraphy (GES) have informed us about changes in the behavior of the stomach before and after the operation. AIM: The objective of this study is a short-term scintigraphic evaluation of GE in post-PD patients for solid food before (baseline) and after the operation for 30 days. METHODS: Between April 2016 and September 2019, 30 patients who underwent PD were investigated for the effect on GE of solids. GE scan GES was performed for the evaluation of solids in GE on pre-operative and post-operative day 30. The operative time, blood loss, the specimens’ pathology and resection margins, the interpretation of the GES study, and finally the hospital course data were all gathered and subjected to statistical analysis. RESULTS: Nineteen patients developed delayed GE (DGE) while four developed rapid GE or dumping. The type of pancreatic reconstruction affected the GE dynamics. DGE was evident in all cases with pancreaticogastrostomy (PG), while it was observed only in 4 patients of 15 with pancreaticojejunostomy (PJ). Seven cases developed a post-operative pancreatic fistula (POPF), 3 after PG versus 4 after PJ, and were all successfully managed conservatively. CONCLUSION: The reconstruction method of the remnant pancreas could affect the dynamics of GE. The DGE to solids was witnessed more in cases reconstructed by PG and less in cases with PJ. Post-operative complications associated, such as POPF, are factors associated with DGE.
The Galaxy correlation hierarchy in perturbation theory

I calculate the evolution of cosmological density correlation functions to lowest nonvanishing order in perturbation theory for an initially random Gaussian distribution. The three-point function so obtained scales with size as in the continuous hierarchy model, but there is a residual nontrival dependence on shape of the reduced three-point amplitude Q. The average value Q-bar = 34/21-(1/6). gamma. is consistent with observations in the nonperturbative regime. The four-point function is also hierarchical in form, with amplitudes R/sub a/ = (34/21)/sup 2/ and R-bar/sub b/ = 682/189. The perturbation expansion in fact gives kappa/sub N/proportionalxi/sup N/-1 for the reduced correlation function kappa/sub N/ to all orders N. A graphical technique enumerates the terms which appear in kappa/sub N/.
Orbital Stability of the Uranian Satellite System

Abstract We have numerically integrated approximately 500 systems of mutually gravitating bodies which were based on subsets of the uranian satellite system. In each run within a set, the satellite masses were initially multiplied by a common mass enhancement factormf. The simulations were terminated at the “crossing time,”tc, when mutual perturbations excited eccentricities sufficiently large for orbits of a pair of bodies to cross. For a given set,tcis well represented as a power law function ofmfof the formtc= βmfα, where the values of the constants α and β depend on the system; values of α ranging from −13 to −3 are found here. This mass-scaling relationship may have wider implications as a diagnostic for the stability of many orbital configurations. We find that satellite systems which orbit around a significantly oblate planet are slightly more stable than identical systems in orbit about a spherically symmetric planet, presumably because the precession induced by planetary oblateness precludes secular resonances between the moons. Extrapolation of our results suggests that the five classical satellites of Uranus are stable over the age of the solar system (in the absence of tidal torques from the planet). Uranus' inner moons appear far less stable, with Desdemona conceivably colliding with either Cressida or Juliet sometime within the next 4–100 million years (provided the satellite masses adopted here are within a factor of 2 of the correct values). Thus, at least some of Uranus' inner moons are probably “young” by geological standards. Implications for the origin and evolution of these satellites are discussed.
Modeling of Flux Rope Coronal Mass Ejections

We present a forward-modeling technique for flux rope-like CMEs using an empirically defined model of a flux rope, the graduated cylindrical shell (GCS). To compare it with white-light coronagraph observations, we assume an electron distribution through the GCS and derive synthetic images in total and polarized brightness for various projections of the model using a Thomson scattering ray-tracing program. We test our forward modeling technique on 34 LASCO CMEs analyzed by Cremades & Bothmer. We are able to reproduce the CME morphology and derive the electron density (at the CME front) of these events using multi-instrument observations (MDI, Hα, EIT, LASCO) under the assumption of self-similar expansion. This study suggests that a flux rope-like structure is a good description for these events. We also find that we need to invoke a deflection and/or rotation of the structure relative to the position and orientation of the source region in most cases. Finally, we demonstrate an original technique to fit the electron density of the CME leading edge. We find that, on average, the peak of the density at the CME front is 7.5 times that in the equatorial model of Saito et al., and can reach ~22 times the model in some cases.

The effects of individual differences in native perception on discrimination of a novel non-native contrast

Native (L1) phonetic categories can constrain the perception of non-native contrasts which deviate from the listener’s L1 (Best & Tyler, 2007; Flege, 1995). Yet, some individuals are remarkably successful at accurately perceiving non-native sounds (e.g., Bongaerts, van Summeren, Planken, & Schils, 1997). We hypothesize that compact L1 categories give an initial advantage in distinguishing non-native contrasts. Sixty-eight Spanish monolinguals were tested on the degree of compactness of their native category /i/, measured through a goodness-of-fit rating task. Participants listened to synthesized variants of the Spanish /i/ vowel (differing in F1, F2, or both) and rated them as either good or bad exemplars of their representation of this category. An individual /i/ compactness index was calculated for each participant and related to the individual perceived dissimilarity score for the novel Russian contrast /i – ɨ/. The Russian contrast /i – ɨ/ is a problematic contrast to perceive for Spanish speakers due to the absence of /ɨ/ in the Spanish vowel inventory, a sound acoustically very similar to /i/. In this study, the compactness of the L1 category /i/ weakly predicted perceptual sensitivity (dissimilarity scores) for the Russian contrast /i – ɨ/.
A Multi-Agent Extension of PDDL3.1

Despite a recent increase of research activity in the field of multi-agent planning there is still no de-facto standard for the description of multi-agent planning problems similarly to the Planning Domain Definition Language (PDDL) in case of deterministic single-agent planning. For this reason, in this paper a multi-agent extension of the currently latest official version of PDDL (3.1) is proposed together with a corresponding multi-agent planning track for the International Planning Competition (IPC). Our aim is to allow for a more direct comparison of planning systems and approaches, a greater reuse of research, and a more coordinated development in the field. Multi-agent planning is fundamentally different from the single-agent case with a broad range of applications (e.g. multi-robot domains). Not only is it inherently harder because of an exponential increase of the number of actions in general, but among others also constructive/destructive synergies of concurrent actions, and agents’ different abilities and goals may need to be considered. The proposed multi-agent extension copes with these issues and allows planning both for and by agents even in temporal, numeric domains. It implies minimal changes to the syntax of PDDL3.1 and the related parsers.
Levels to Address Human-Nature Relations in Cities Through Geo-data Processing Strategies: A Mini-Review

: This mini-review examines the use of GIS analyses in studies that explore human-nature relations in urban contexts. Publications were retrieved using the same search terms in Google Scholar and Web of Science, sorted by relevance, and the resulting first 30 publications from each database were considered for this review. For the purpose of this mini-review, a typology was developed to characterize publications according to level of approach, human-nature interaction, scientific purpose of quantification and level of GIS technique. Our results indicate that there are very few urban human-nature publications that use GIS techniques (n=7). The resulting seven publications were grouped whether they used GIS for mapping, spatial analyses to produce explanatory variables, or in combina-tion with participatory techniques. Our results indicate that geo-data is currently underused in studies examining urban human-nature relations.
Machine learning privacy : analysis and implementation of model extraction attacks

The rise in popularity and the large amount of improvements done to Machine Learning (ML) resulted in the emergence of a new type of attack called model extraction attack. Model extraction attacks are privacy attacks, which aim to extract information about a victim model or even steal its functionality. These types of attacks are being heavily researched, however, it is very hard to perform comparisons between the proposed papers. In this work, we present MET, which implements state-of-the-art model extraction attacks on arbitrary ML models and datasets. Using the tool, we performed a comprehensive comparison between the implemented attacks to see how they perform under different settings. Our results show that in the case of black-box scenarios, the attacks perform similarly. Based on the results, we propose and implement improvements for some of the attacks both in terms of speed and performance.
Systematic uncertainty and thermochronology of the Great Unconformity? A review of Fox et al. 2022, gchron-2022-23

While this may at first seem like a fine point, in the context of recent debate about the Great Unconformity it is absolutely critical that these two should not be conflated, given that the answers to these two questions are almost certainly not the same: specifically, the answer to the former question is (given enough data from different locations using different and/or multiple chronometers) quite likely yes, even though the answer to the latter question is quite likely no.

Interactions of Elementary Particles in Dual Parton Model

We analyze the origins of interactions of elementary particles with the string model of Nambu and Susskind. Strong, electromagnetic and weak interactions originate from the dif­ ferent partons in the hadrons. Partons in the center of the string have nothing to do with weak interactions. Recently the parton models of hadrons are proposed by many authors and the hadronic interactions are explained quite well by the models. In this place, we will try to analyze the origins of hadronic interactions*> with the string model of Susskind1> and Nambu.2> According to them, hadrons are made of one string and ~hen it moves through space-time, it sweeps out a two-dimensional world sheet. This sheet is viewed as a simply connected region of the complex plane such as an infinite strip o<o<n, - oo<A<oo. The dynamical degrees of freedom X,. (O, A) defining the four-dimensional space-time location of the point ((),A) satisfy
Proceedings of the 202 2 Improving Scientific Software Conference

Many elds within scienti c computing have embraced advances in big-data analysis and machine learning as components of applications; these mixed approaches often require the deployment of large, distributed and complicated work ows that may combine training neural networks, performing simulations, running inference, and performing database queries and data analysis in asynchronous, parallel and pipelined execution frameworks. Such a shift has brought into focus the need for scalable, e cient work ow management solutions with reproducibility, error and provenance handling, traceability, and checkpoint-restart capabilities, among other needs. Here, we discuss challenges and best-practices for deploying exascale-generation computational science work ows on resources at the Oak Ridge Leadership Computing Facility (OLCF). We present our experiences with large-scale deployment of distributed work ows on the Summit supercomputer, including for bioinformatics and computational biophysics and deep learning model optimization.We also present problems and solutions created by working within a Python-centric software base on traditional High Performance Computing (HPC) systems; addressing such issues will be required before the convergence of HPC, Arti cial Intelligence (AI), and data science can be fully realized. Our results point to a wealth of exciting new possibilities for harnessing this convergence to tackle new scienti c challenges.

Enhancement of thermal stability and water resistance in yttrium-doped GeO2/Ge gate stack

We have systematically investigated the material and electrical properties of yttrium-doped GeO2 (Y-GeO2) on Germanium (Ge). A significant improvement of both thermal stability and water resistance were demonstrated by Y-GeO2/Ge stack, compared to that of pure GeO2/Ge stack. The excellent electrical properties of Y-GeO2/Ge stacks with low Dit were presented as well as enhancement of dielectric constant in Y-GeO2 layer, which is beneficial for further equivalent oxide thickness scaling of Ge gate stack. The improvement of thermal stability and water resistance are discussed both in terms of the Gibbs free energy lowering and network modification of Y-GeO2.
Trade Liberalization and Performance Of Private Sector In Rwanda: A Case Study of PSF Nyagatare District

- The objective of this study was to evaluate the effect of trade liberalization on performance of private sector in Rwanda and in Nyagatare district in particular during 2015-2017. The collected data was analyzed through SPSS software from 44 respondents selected among 120 members of PSF Nyagatare. For data analysis, SPSS21 was used for descriptive statistic and correlation analysis. The findings for the first objective shows the overall of 3.03 and standard deviation of . 547 indicating that trade liberalization plays an important role on the performance of private sector in Nyagatare district during the period of study. The findings for the second objective indicated the mean 4.15 and . 481 standard deviation as high mean. That means that the effectiveness of private sector in Nyagatare district depends on trade liberalization policies implemented and followed by PSF members in their doing business of importing or exporting products with neighboring countries. The third objective indicated challenges hindering private sector members including poor infrastructures, competition, poor quality products and transport cots. The overall mean of 4.23 and . 513 of standard deviation, showing that they really exist and need preventing correcting measures. The Pearson’s correlation obtained was 0.877 at a two-tailed level of significance
Methodological Quality of Physical Therapy–Related Trials Published in Open Access and Subscription Journal

Objective We aimed to compare the methodological quality of physical therapy–related trials published in open access with that of trials published in subscription-based journals, adjusting for subdiscipline, intervention type, endorsement of the Consolidated Standards of Reporting Trials, impact factor, and publication language. Design In this meta-epidemiological study, we searched the Physiotherapy Evidence Database on May 8, 2021, to include any physical therapy–related trials published from January 1, 2020. We extracted variables such as Consolidated Standards of Reporting Trials endorsement, the Physiotherapy Evidence Database score, and publication type. We compared the Physiotherapy Evidence Database score between the publication types using a multivariable generalized estimating equation by adjusting for covariates. Results A total of 2743 trials were included, with a mean total Physiotherapy Evidence Database score (standard deviation) of 5.8 (±1.5). Trials from open access journals had a lower total Physiotherapy Evidence Database score than those from subscription-based journals (5.5 ± 1.5 vs. 5.9 ± 1.5, mean difference = −0.4; 95% confidence interval = 0.3–0.5). Generalized estimating equation revealed that open access publication was significantly associated with the total Physiotherapy Evidence Database score (mean difference = −0.42; P < 0.001). Conclusions In the recent physical therapy–related trials, open access publications demonstrated lower methodological quality than subscription-based publications, although with a small difference.
