First Autochthonous Report on Cattle Babesia naoakii in Central Java, Indonesia, and Identification of Haemaphysalis bispinosa Ticks in the Investigated Area

In tropical countries, clinical bovine babesiosis is a tick-borne disease primarily caused by Babesia bovis and Babesia bigemina. Here, we investigated 11 cattle with presumptive diagnosis of clinical babesiosis in Boyolali district, Central Java, Indonesia. The majority of the animals were anemic, as evidenced by lower hematocrit, hemoglobin concentration, and red blood cell counts than the normal ranges. Blood DNA was analyzed by a PCR assay targeting the 18S rRNA-ITS region of babesial origin, and the results confirmed that the cattle were infected with Babesia species. The sequencing and phylogenetic analyses demonstrated that the animals were infected with Babesia naoakii. This is the first report of B. naoakii in Indonesia and of B. naoakii-induced clinical bovine babesiosis outside of Sri Lanka. B. naoakii causes a persistent infection, as indicated by positive PCR results for serial blood samples of the circulatory system taken two weeks after treatment. Consequently, subclinical or newly recovered cattle may serve as potential intermediate hosts and infect ticks as definitive hosts to complete the life cycle. To identify potential tick vectors, we collected ticks from cattle, including 11 animals with clinical babesiosis. Based on the morphology and the mitochondrial cytochrome c oxidase subunit 1 (COX1) of collected ticks, we found that all of the collected ticks were Haemaphysalis bispinosa, identifying this tick species as a potential vector of B. naoakii in Indonesia. In this study, the evaluation of local farmers’ awareness and practices regarding tick-borne diseases is presented, as disease prevention is also reliant on the implementation of strategies for vector control. Since livestock activities in Java represent the country’s busiest animal trade, thereby the spread of disease to other regions is possible through anthropogenic factors. In conclusion, B. naoakii is a causative pathogen of clinical bovine babesiosis autochthonously occurred in this report and further research on B. naoakii-infection is required in other regions of the country. The prompt treatment of the disease seemed crucial for animal survival, which implies the necessity of early diagnosis and a sensitive detection method.
Canagliflozin Improves Myocardial Perfusion, Fibrosis, and Function in a Swine Model of Chronic Myocardial Ischemia

Background Sodium‐glucose cotransporter‐2 inhibitors are cardioprotective independent of glucose control, as demonstrated in animal models of acute myocardial ischemia and clinical trials. The functional and molecular mechanisms of these benefits in the setting of chronic myocardial ischemia are poorly defined. The purpose of this study is to determine the effects of canagliflozin therapy on myocardial perfusion, fibrosis, and function in a large animal model of chronic myocardial ischemia. Methods and Results Yorkshire swine underwent placement of an ameroid constrictor to the left circumflex artery to induce chronic myocardial ischemia. Two weeks later, pigs received either no drug (n=8) or 300 mg sodium‐glucose cotransporter‐2 inhibitor canagliflozin orally, daily (n=8). Treatment continued for 5 weeks, followed by hemodynamic measurements, harvest, and tissue analysis. Canagliflozin therapy was associated with increased stroke volume and stroke work and decreased left ventricular stiffness compared with controls. The canagliflozin group had improved perfusion to ischemic myocardium compared with controls, without differences in arteriolar or capillary density. Canagliflozin was associated with decreased interstitial and perivascular fibrosis in chronically ischemic tissue, with reduced Jak/STAT (Janus kinase/signal transducer and activator of transcription) signaling compared with controls. In ischemic myocardium of the canagliflozin group, there was increased expression and activation of adenosine monophosphate‐activated protein kinase, decreased activation of endothelial nitric oxide synthase, and unchanged total endothelial nitric oxide synthase. Canagliflozin therapy reduced total protein oxidation and increased expression of mitochondrial antioxidant superoxide dismutase 2 compared with controls. Conclusions In the setting of chronic myocardial ischemia, canagliflozin therapy improves myocardial function and perfusion to ischemic territory, without changes in collateralization. Attenuation of fibrosis via reduced Jak/STAT signaling, activation of adenosine monophosphate‐activated protein kinase, and antioxidant signaling may contribute to these effects.
The S III intercombination multiplet: radiative and electron excitation data

The author presents radiative transition probabilities and effective collision strengths for electron impact excitation of the intercombination multiplet 3s23p2 3P-3s3p3 5So of S III at 1720 AA. The author finds that resonances are important in the calculation of the collision strength. Their positions and sizes are sensitive to the description of the target ion; hence the results for the effective collisions strengths for low values of electron temperature are not definitive. Effective collision strengths are also given for other low-lying intercombination transitions.
Two electrons in a harmonic potential: an approximate analytical solution

A complete analytical approach is used to study the problem of two electrons in a harmonic potential. The effective potential of the combined system is described as the sum of the harmonic and anharmonic potentials. For large separation distances between two electrons, it is possible to ignore the anharmonic contribution and hence the combined system behaves as a harmonic oscillator. The frequency of the modified oscillator depends on the separation distance between the two electrons and on the angular quantum momentum. When there is a small separation distance between the two electrons, the anharmonic contributions become significant and the system does not have an exact solution. The anharmonic constant, however, does not have explicit dependence on the frequency of the harmonic potential responsible for the confinement. We give a rough estimate of the contribution of anharmonic potentials. As the angular momentum increases, we observe that the contribution of the anharmonic constant becomes negligibly small. The present approximate analytical solution is critically compared with other, existing solutions.
Transient oscillations in NMR cross-polarization experiments in solids

Strong transient oscillations have been observed in proton-carbon-13 cross-polarization experiments in a ferrocene single crystal. These oscillations are in contrast with the usually observed exponential behavior of cross polarization. They are manifestations of coherence effects caused by the dipolar coupling of the carbon-13 to the directly bound proton. A simple model is described which explains the observations.
Spectrum-Aware Compact Reconfigurable UHF Antenna for Interweave Cognitive Radio

This paper presents a compact ultra-high frequency (UHF) folded antenna design that relies on a single radio frequency micro-electro-mechanical switch (RF-MEMS) to reconfigure its frequency of operation between 575 MHz and 760 MHz. The reconfigurable multi-layered antenna design has a volumetric folded topology with total dimensions of 40×40mm2; equivalent to 0. 11λx0. 11λ at 575 MHz. The antenna is fabricated and tested where the measurements agree well with the simulation results. The antenna exhibits a radiation efficiency of 40% at 575 MHz and 62% at 760 MHz. Furthermore, the proposed antenna is tested in a cognitive radio environment to validate its ability to adapt to cognitive input and tune its performance across white space within the UHF band. This is achieved by relying on a trained classifier model that is embedded within a microcontroller to autonomously control the state of the integrated switch based on which channel is idle.
Prognostic significance for recurrence of fibroblast growth factor receptor 2 in intrahepatic cholangiocarcinoma patients undergoing curative hepatic resection

The fibroblast growth factor receptor 2 (FGFR2) fusion gene is frequently found as a genetic abnormality in the FGFR pathway in patients with intrahepatic cholangiocarcinoma (ICC). The FGFR fusion protein, produced from the FGFR fusion gene, is thought to cause tumor cell growth. To date, there have been few reports on the relationship between pathologic FGFR2 expression and prognosis in patients who have undergone hepatectomy for ICC, and on the relationship between FGFR2 and tumor‐infiltrating lymphocytes (TILs).
Recovery of Three-Dimensional Wind and Temperature Fields from Simulated Single-Doppler Radar Data

Abstract A method for recovering the full three-dimensional wind and temperature fields from single-Doppler radar data is developed and demonstrated. This method uses a dynamic model, and attempts to determine the initial conditions of the unobserved flow and thermodynamic fields that have generated the time sequence of observed fields. A cost function is defined to measure the difference between the model solutions of the observed variables and the observations. A set of adjoint equations is constructed to determine the sensitivity of the cost function to initial state errors in those not observed. The initial state variables are then adjusted to minimize those errors. Several experiments are conducted using simulated observations produced by a control run of a dry convection model. It is shown that the method is able to determine the spatial structures of the unobserved velocity components and temperature effectively; and the performance is enhanced by the use of a temporal smoothness constraint.

Social and Environmental Accountabilities of the Nepalese Cell Phone Operators

Background: Social and environmental accountabilities are the ideas of individuals/organisations working for society to maintain economic and environmental equilibrium. Society's perception of organizations is shaped by how they report on their social and environmental effects. Objective: This study aimed to examine the impression of social and environmental indicators concerning organizational performance from the perspective of the customers of Nepalese mobile phone service providers. Materials and Methods: The study employed a stratified non-probability sampling technique and collected primary data from 329 GSM users of the Nepalese cell phone operator companies with an organised survey questionnaire. The survey questionnaire contained 17 questions about demographic and general information, social and environmental impressions, and organisational performance. The study variables' questions were organised with a 6-point Likert-type scale and employed structural equation modelling and path analysis to get the study's objective. Results: Two observed variables out of five within the social performance (β = 0.812, p < 0.01) and all four observed variables within the environmental performance (β = 0.972, p < 0.01) significantly contributed to social and environmental performance. The social and environmental performance with six observable and two latent variables had a substantial influence (β = 0.877, p < 0.01) on organisational performance. Conclusions: The study presents a new subjective lens and an approach for recognising, analysing, and spreading social and environmental impacts. It expands the scope of performance evaluation by focusing on social and environmental variables generally overlooked by businesses, particularly in Nepal. Limitations/Recommendations: This analysis was limited to GSM service and based on primary data by covering a single-dimensional performance metric. The study's outcomes can generate opportunities for building more appropriate non-financial performance metrics impacting organisational performance. Originality: This paper has not been published elsewhere.
Assessing Red Fox (Vulpes vulpes) Demographics to Monitor Wildlife Diseases: A Spotlight on Echinococcus multilocularis

The assessment of red fox population density is considered relevant to the surveillance of zoonotic agents vectored by this species. However, density is difficult to estimate reliably, since the ecological plasticity and elusive behavior of this carnivore hinder classic methods of inference. In this study, red fox population density was estimated using a non-invasive molecular spatial capture-recapture (SCR) approach in two study areas: one in a known hotspot of the zoonotic cestode Echinococcus multilocularis, and another naïve to the parasite. Parasitological investigations on collected samples confirmed the presence of the parasite exclusively in the former area; the SCR results indicated a higher fox population density in the control area than in the hotspot, suggesting either that the relationship between fox density and parasite prevalence is not linear and/or the existence of other latent factors supporting the parasitic cycle in the known focus. In addition, fox spotlight count data for the two study areas were used to estimate the index of kilometric abundance (IKA). Although this method is cheaper and less time-consuming than SCR, IKA values were the highest in the areas with the lower molecular SCR density estimates, confirming that IKA should be regarded as a relative index only.
Pulsed high-energy gamma rays from the Crab Nebula

The Cornell 100-inch gas-Cerenkov gamma -ray telescope has detected pulsed radiation at hundreds of MeV, up to more than 1 GeV, coincident in time with the optical pulses from NP 0532, and in direction within 1 deg of the Crab Nebula. Two spectral points lie on an extension of the pulsed X-ray spectrum: the expression 0.95E/sup -1.08/ keV cm/sup -2/ s/sup -1/ keV/sup -1/ fits a synthesis of the data from 5 keV to 10/s up 6/ keV. The main pulse and the secondary pulse contain about equal numbers of events and show evidence of being narrower ihan at lower energies. There is weak evidence for further pulse structure in the interval between these two peaks, and also for an unmodulated gamma -ray component about equal to the time-averaged pulsed flux. The pulsar and nebular spectra appear to steepen somewhere between 1.5 and 150 GeV. No pulsed flux from NP 0525 was detectable in this flight. (auth)
The dissociative photoionization of hydrogen via two-electron excitation at 27.5 eV and 30.5 eV

The kinetic energy spectra of the protons produced in the dissociative photoionization of H2 directed predominantly along the E vector of a photon beam have been measured at photon energies of 27.5 and 30.5 eV. Protons arising from autoionization of the lowest two-electron excited states (1 Sigma +u) exhibit an energy distribution which, unlike previous experimental results, is in accord with theory.
Acoustics of the avian vocal tract

The general principles underlying the acoustic performance of the avian vocal tract are examined both theoretically and experimentally. The formantresonances produced both by the total vocal tract and by the bronchial tubes are evaluated quantitatively, and their dependence upon anatomical parameters is investigated. A simplified cylindrical model for the beak is examined theoretically, and experimental results are presented that confirm the predictions of the theory for this model. A similar theoretical and experimental investigation using a more realistic conical beak model is also reported, and behaves as predicted. Finally a theoretical study of the effect of mouth volume, as influenced by tongue position, is integrated with these other studies to produce a complete analysis. The implications of these studies for understanding the acoustical behavior of avian vocal tracts are discussed.
Numerical Experiments in Turbulent Natural Convection Using Two-Equation Eddy-Viscosity Models

This work is focused on the simulation and prediction of turbulent natural convection flows by means of two-equation eddy-viscosity models. In order to show the generality, precision, and numerical issues related to these models under natural convection, three different buoyancy-driven cavities have been simulated: a tall cavity with a 30:1 aspect ratio, a cavity with a 5:1 aspect ratio, and, finally, a 4:1 aspect ratio cavity. All cases are solved under moderate and/or transitional Rayleigh numbers (2.43 × 10 10 , 5 ×10 10 , and ×10 10 , respectively) and all simulations are compared to experimental and/or direct numerical simulation data available in literature. These different situations allow to check the applicability of two-equation eddy-viscosity models in buoyancy-driven flows, giving criteria on computational effort/precision and their physical behavior.
Mobility and Energy Management in Electric Vehicle Based Mobility-on-Demand Systems: Models and Solutions

An electric vehicle based mobility-on-demand (EMoD) system provides shared transportation (e.g., car-sharing or ride-sharing) to satisfy customers’ individual mobility demands. It has been recognized as a vital alternative form of transportation between public and private transportations in future sustainable cities. Constrained by the long charging time and limited driving range of EVs, an operator of an EMoD system demands for decision-making models and algorithms to manage the mobility and energy of EVs to best serve customers with least costs. In this paper, we propose a stochastic dynamic program (DP) to model three operational decisions of the EMoD system: i) dispatching EVs to serve mobility demand from customers, ii) repositioning EVs to accommodate the unbalanced mobility demands between service regions, and iii) recharging EVs to maintain their sufficient state-of-charge levels. To handle this large-scale DP problem, we first observe and prove that it has a coordinate-wise concave value function. Based on this structural property, we propose to use a separable piecewise linear function to approximate the value function and design an approximation-based algorithm to efficiently derive the decision policy. Numerical tests show that our proposed algorithm significantly outperforms the existing model-free approaches (e.g., greedy heuristic and Q-learning) that fail to take into account the structural properties of the DP problem.
Predictive Modeling of Stress in the Healthcare Industry During COVID-19: A Novel Approach Using XGBoost, SHAP Values, and Tree Explainer

There was a substantial medicine shortage and an increase in morbidity due to the second wave of the COVID-19 pandemic in India. This pandemic has also had a drastic impact on healthcare professionals' psychological health as they were surrounded by suffering, death, and isolation. Healthcare practitioners in North India were sent a self-administered questionnaire based on the COVID-19 Stress Scale (N = 436) from March to May 2021. With 10-fold cross-validation, extreme gradient boosting (XGBoost) was used to predict the individual stress levels. XGBoost classifier was applied, and classification accuracy was 88%. The results of this research show that approximately 52.6% of healthcare specialists in the dataset exceed the severe psychiatric morbidity standards. Further, to determine which attribute had a significant impact on stress prediction, advanced techniques (SHAP values), and tree explainer were applied. The two most significant stress predictors were found to be medicine shortage and trouble in concentrating.
Zinc Sulfate and Omega-3: Do They Have a Role in Environmental Enteric Dysfunction ?

Introduction: Environmental enteric dysfunction (EED) is a subclinical, chronic inflammatory condition of the gut. The purpose of the study: The purpose of this study is to evaluate the effects of zinc sulphate and omega-3 supplementation on anthropometric measurements and faecal EED biomarkers (α-1-antitrypsin (AAT), Neopterin (NEO), and Myeloperoxidase (MPO) in underweight and stunted children as an intervention for EED. Subjects and Methods: An interventional study included 105 underweight and stunted children, divided into two subgroups: one subjected to intervention with zinc supplementation (55 children) and the other subjected to intervention with omega-3 supplementation (50 children) for 6 months. Assessment of anthropometric measurements and faecal EED biomarkers: AAT, NEO, and MPO. Results: Regarding the zinc intervention group, post-intervention weight, weight z score, height, height z score, and BMI z score were highly significantly improved after 6 months of zinc supplementation (p value ≤ 0.001). Serum zinc level was highly significant increased after supplementation (p value ≤ 0.001), while AAT and NEO were highly significant and significant decreased (p value ≤ 0.001) (p value ≤ 0.05) respectively. Regarding the omega-3 intervention group, post-intervention weight, weight z score, height, and height z score were highly significantly improved after 6 months of omega-3 supplementation (p value ≤ 0.001). Meanwhile, no significant change was observed for serum iron and zinc level (p value ≥ 0.05) or EED faecal markers except for AAT, which was highly significant for decreasing after supplementation (p value ≤ 0.001). A significant increase in weight, height, and serum zinc level was observed in the zinc supplementation group more than in the omega-3 supplementation group (p value ≤ 0.05). Alongside no significant difference post intervention in EED fecal markers between the two groups (p value ≥ 0.05). Conclusion: No definite drug intervention or supplementation is documented as appropriate management. Zinc sulphate supplementation is thought to be more beneficial than omega-3 supplementation, as evidenced by the improvement of anthropometric measurements and decrease of EED faecal markers.
Regional Features of the Placement of Light Industry Enterprises in Kazakhstan

The article is devoted to the issues of the location of the productive forces of light industry in the regions of Kazakhstan, which is influenced not only by the factors of the availability of natural resources, favorable geographical location, but also by factors of "second nature", in particular, the likelihood of agglomeration effects from crowding and the possibility of economies of scale. The analysis of geographical concentration and regional specialization reflects the general trends in the placement of industrial production, provides the necessary information basis for a balanced economic policy. The localization coefficient, concentration and specialization indices of Herfindahl–Hirschman and Krugman were used as methodological assessment tools in the study. The high concentration of industrial production of light industry enterprises in the regions of the country was revealed. The results obtained can be used in scientific research to analyze the distribution of productive forces, assess the development of agglomeration processes, as recommendations for conducting economic policy in the regions.
