Molecular Epidemiology of Cystic Echinococcosis in Rural Baluchistan, Pakistan: A Cross-Sectional Study

Cystic echinococcosis (CE), or hydatid cyst disease (HCD), is a zoonosis of significant importance caused by the cestode of Echinococcus granulosus sensu lato (s. l.) that affects mainly nomadic populations and has substantial economic consequences. Due to the 76% rural and nomadic population, Baluchistan is a highly endemic region in Pakistan for CE; however, it has not yet been investigated for CE. For this purpose, this study was carried out to investigate the molecular epidemiology of CE in this region. In total, 23 human hydatid cyst samples were collected from tertiary health care units in Baluchistan and processed for DNA extraction, which was then followed by sequencing of the cox1 mitochondrial gene of all 23 collected samples, genotyping, and phylogenetic and haplotype analysis. Most subjects were livestock owners (39.13%) in rural settings (73.91%). Most patients (73.19%) were pet owners (dogs) and used water from open sources for drinking. The liver was the most affected organ (52.17%), followed by the lungs (17.39%). Sequence analysis based on the cox1 gene revealed that EG genotype 1 (G1) was the most prevalent (56.52%), followed by G3 (34.78%), while some samples (8.7%) were identified as the Echinococcus canadensis (G6/7) genotype. A total of five haplotypes were detected with high haplotype diversity (0.80) and low nucleotide diversity (0.033). Phylogenetic analysis revealed two diverse sub-clades, each of G1 and G3 isolates from Baluchistan, that were evolutionarily related to previously reported G1 and G3 isolates from Pakistan and China. On the other hand, the G6/7 isolates of this study were evolutionarily identical to the already reported G6/7 isolates from Pakistan, Turkey, and Kazakhstan. This study concludes that diverse G1 and G3 EG isolates are present in this part of Pakistan, while the G6/G7 genotype was reported for the first time from Baluchistan.
Convective Drying of Purple Basil (Ocimum basilicum L.) Leaves and Stability of Chlorophyll and Phenolic Compounds during the Process

This study evaluated the effect of convective drying on the degradation of color and phenolic compounds of purple basil (Ocimum basilicum L.) leaves, and the hygroscopic behavior of dried leaves. The fresh leaves underwent drying at 40 °C, 50 °C, 60 °C, and 70 °C. Degradation of chlorophyll, flavonoids, and phenolic compounds were evaluated during drying and the hygroscopicity was evaluated through the moisture sorption isotherms. The drying mathematical modeling and the moisture sorption data were performed. The effective diffusivity for the drying increased from 4.93 × 10−10 m2/s at 40 °C to 18.96 × 10−10 m2/s at 70 °C, and the activation energy value (39.30 kJ/mol) showed that the leaves present temperature sensibility. The leaves dried at 40 °C had less degradation of phenolic compounds and color variation, but the drying process was too slow for practical purposes. Modified Page, Diffusion Approximation, and Verna models had excellent accuracy in drying kinetics. The isotherms showed that, in environments with relative humidity above 50%, the purple basil leaves are more susceptible to water gain, and at 8.83 g H2O/100 g db moisture, it guarantees the microbiological stability of the dried leaves. The Oswin model was the most suitable for estimating the moisture sorption isotherms of the dried leaves.
Seroprevalence of porcine cysticercosis in Maharashtra

Porcine cysticercosis is caused by Cysticercus cellulosae, a larval stage of parasite Taenia solium. Humans get infected by consuming eggs of T. solium through contamination of food and water. Owing to economic and zoonotic importance of porcine cysticercosis in India, a research plan was designed to study seroprevalence of cysticercosis in Maharashtra. Blood samples (172) were collected from different regions. The seroprevalence of cysticercosis by ELISA, FTA and western blot was 8.5%, 7.5% and 6.98%, respectively. Cohenâ€™s kappa coefficient was used to analyse for the percentage of agreement with meat inspection test. The sensitivity and specificity between ELISA and FTA (k=0.958) showed no significant difference. The study indicates that ELISA and FTA were more sensitive than western blot. Western blot of whole cyst antigen revealed immunoreactivity at 42 to 250 kDa bands. The seroprevalence of porcine cysticercosis in Maharashtra had increased significantly. FTA is easier to perform and faster than ELISA test. This simple test appears to be suitable for practical use at field level, especially for largescale ante-mortem screening of pigs against cysticercosis.
Mean convergence of Fourier series on compact Lie groups

The main result is an L? mean convergence theorem for the partial sums of the Fourier series of a class function on a compact semi-simple Lie group. A central element in the proof is a Lie group-Lie algebra analog of the theorems in classical Fourier analysis that allow one to pass back and forth between multiplier operators for Fourier series in several variables and multiplier operators for the Fourier transform in Euclidean space. To obtain the Lp mean convergence theorem, the theory of the Hilbert transform with weight function is needed.
Accuracy Gains from Unfocused Feedback: Dynamic Written Corrective Feedback as Meaningful Pedagogy

Background. A primary question among L2 writing instructors is how to best deliver written corrective feedback (WCF) to support student learning. One promising WCF method is Dynamic Written Corrective Feedback, in which instructors provide unfocused/comprehensive feedback using a coding system coupled with regular rounds of editing on short, in-class student-written paragraphs. Purpose. In this study, I explored the impact on student accuracy of unfocused DWCF on brief student-produced texts in intermediate and advanced developmental ESL writing classes. This study was motivated by the desire to evaluate this pedagogical intervention and determine if it should continue to be implemented in our developmental writing program. Methods. Utilizing a quasi-experimental research design using t-test analyses, I coded, tallied, and contrasted the errors in term-final paragraphs of 130 students who participated in classes that used DWCF with 79 students in control sections that did not include DWCF. Results. I found statistically significant improvements in the treatment sections at both levels for nearly all error types (including but not limited to verb form/tense, sentence structure, work order, work choice, determiner, noun form, and punctuation errors; the only error type that did not return significance differences was prepositions at the intermediate level). These results suggest that unfocused written corrective feedback may be effectively used in multilingual writing classrooms, at least given certain parameters to help ensure that feedback is manageable and specific, per the DWCF process. Conclusion. This study complicates the so-called best practices stemming from WCF research in which many researchers have advocated for WCF that addresses only a small number of error types. Rather, providing that feedback practices are kept manageable and accessible for the students, multilingual students may effectively process and apply unfocused feedback to their own writing.
Awareness of stroke signs, symptoms, and risk factors among Jazan University students: An analytic cross-sectional study from Jazan, Saudi Arabia

In the Kingdom of Saudi Arabia, the lifetime risk of stroke is estimated to be between 23% and 28.9%, whereas in Jazan region of the Kingdom there is a high prevalence of sickle cell anemia, which is known to increase the risk of stroke. This study aimed to assess awareness of stroke signs, symptoms, and risk factors among university students in the southern region of Saudi Arabia. In this analytical cross-sectional study, data obtained through an online questionnaire were collected from 897 university students. Data were entered, cleaned, and analyzed using SPSS (IBM, Chicago IL) software version 28. Knowledge was assessed using both open- and closed-ended questions (CEQ). The participants were predominantly female (72%), single (86.8%), a fifth had relatives with cerebrovascular accident (CVA), and a third knew a person with CVA. The open-ended questions showed that 11.8% did not know any symptoms or signs and 25% knew only 1, while in the CEQs, hypertension was selected by 83.0%. Regarding knowledge about symptoms and signs, 33.7% and 21.9% recognized weakness and speech disturbance, respectively, whereas in the CEQs, around 60% selected others. Regarding actions that should be taken if CVA is suspected, >80% preferred going directly to the hospital. The best time to seek professional care was considered to be within 4 hours by 47.5%, 10.3% suggested a later timing, and 42.3% had no knowledge of what to do. Multivariate logistic regression revealed that pursuing a health-related specialty and previous stroke experience in close relatives were significantly associated with good stroke knowledge. The level of knowledge and correct timing and action among participants were better than those reported nationally and internationally. However, there is still room for improvement in awareness, which is recommended to improve the outcomes.
Molecular dynamics study of corrosion behavior of iron with vacancies exposed to lead‐bismuth eutectic

The corrosion behavior of iron with vacancies in a liquid lead‐bismuth eutectic environment is simulated by molecular dynamics with embedded‐atom model potential at 700–1073 K. The vacancy is substituted into Fe crystal with the percentage of 0%, 0.2%, 0.4%, 1.0%, and 2.0% to investigate the effect of the vacancy on the corrosion behavior of iron. By evaluating the time‐dependences of penetration depths and the number of penetrating Pb and Bi atoms and also observing the trajectory of a penetrating Bi atom, we concluded that temperature and vacancy will enhance the corrosion behavior of iron in liquid lead‐bismuth, and the corrosivity of Bi atom is larger than that of Pb atom. The result is supported by the calculated substitutional energies of each Pb or Bi atom with a Fe atom or vacancy, which are in the order of EvacBi
The formation of emission lines in quasars and Seyfert nuclei

The photoionization and heating throughout a quasar emission-line cloud optically thick at the Lyman edge are calculated. Photoionization and collisional ionization from excited states of hydrogen are included, which maintain a substantial electron fraction after the exhaustion of Lyman continuum photons halts ground-state photoionization. Observed values are explained for Ly-alpha/H-beta, H-alpha/H-beta, P-alpha/H-alpha, He I 5876/H-beta, O I 8446/H-alpha, and Mg II 2798/H-beta. The dependence of line strengths on physical conditions is discussed, and plotting Fe II/4570/H-beta versus Balmer continuum/H-beta is suggested. Other observations are also suggested, and the degree of asymmetry is given between the forward and backward emission of lines from a finite slab to make possible the use of comparative line profile studies to elucidate cloud kinematics.
Determining Predictors of True HIV Status Using an Errors-in-Variables Model With Missing Data

We demonstrate a model for categorical data that parallels the MIMIC model for continuous data. The model is equivalent to a latent class model with observed covariates; further, it includes simple handling of missing data. The model is used on data from a large-scale study of HIV that had both biological measures of infection and self-report (missing on some cases). The model allows the determination of sensitivity and specificity of each measure, and an assessment of how well true HIV status can be predicted from characteristics of the individuals in the study.
Predicting BMX Performance with Laboratory Measurements in Elite Riders

ABSTRACT In Bicycle Motocross (BMX) performance is determined by the riders’ sprint ability and power output. Therefore, descriptive and predictive performance assessments through laboratory and field tests are of interest. Twelve members of the Spanish BMX National Team performed 4 laboratory tests, including 1RM in squat, a Wingate test, a 5x6-s repeated sprint test (RST) and a force-velocity profile test. These tests were compared with the riders’ field performance using the best lap of a simulated BMX competition consisting of 6 all-out laps on a standard BMX track. Pearson’s correlation and linear regression analysis showed a significant association (p < 0.05) between the riders’ field performance and the 1RM (r = 0.84; R2 = 0.65), the peak power output in the RST (r = 0.87; R2 = 0.78) and the peak power, the mean power and the lactate production in the Wingate test (r = 0.68–0.77; R2 = 0.14–0.65), as well as maximal power from the force-velocity profile (r = 0.71; R2 = 0.53). The laboratory tests included in this study can show information about BMX riders’ performance, with the highest values for the peak power obtained in the repeated sprint test (78% of the variance in common).
Service Operation Strategy and Service Delivery Strategy to Enhance Business Performance

This study strives to investigate whether the business performance of PT Pertamina (Persero) Integrated Terminal Teluk Kabung can be improved through an effective service operation strategy and service delivery strategy. This study uses primary and secondary data information. The data analysis pulled in this study is descriptive and causal and was obtained through the census method of 104 respondents who are the owners of 136 gas stations spread across West Sumatra. The causality data was then processed using PLS-SEM software. The study results show that some gas station operators in the area complained about PT Pertamina's services to consumers, which were considered slow and inflexible. Internal processes and customer perspectives that prioritize responsiveness capabilities to market needs will potentially improve business performance sustainably.
Bond-orientational order, dislocation loops, and melting of solids and smectic-A liquid crystals

A three-dimensional solid with an equilibrium concentration of unbound dislocation loops displays a resistance to torsion not present in isotropic liquids. There is residual bond-angle order analogous to that found in the two-dimensional hexatic phase. A bulk phase with bond orientational order may be observable in supercooled liquids. Such a phase would display an angular modulation in monodomain x-ray-diffraction patterns, and would give rise to an intrinsic asymmetry in the limits of supercooling and superheating. Bond-angle order may also be present in glasses. A dislocation-loop mechanism for the smectic-$A$\char22{}to-nematic transition implies anisotropic scaling and fixes the ratio of the transverse and longitudinal correlation length exponents.
Bubbles, jets, and clouds in active galactic nuclei

The Blandford and Reese 1974 fluid twin-exhaust model for jet formation is thoroughly investigated. We perform detailed analytic calculations of all aspects of the cavity-nozzle structures for the nonrelativistic case: the preshock flow, the central shock, cavity flow, and the nozzle. Our analytic results are in excellent agreement with recent sophisticated numerical calculations. We find that for a given central confining gas cloud, only a finite range of jet powers is possible. The sound speed ratio between cavity and cloud must be less than 30. Central masses of approx.10/sup 9/ M/sub sun/ within 1 pc are necessary for high-powered (10/sup 46/ ergs s/sup -1/) extragalactic jets. For a fixed confining cloud sound speed C/sub 0/, there are three regimes determined by the central engine's luminosity. For low luminosity, a stream of bubbles emerges; for a middle range of luminosities, a jet forms; for too high a luminosity, large clouds are emitted. In the jet regime we find that L/sub j/approx.C/sup 0//sub 5/ . The critical dependence of jet power on confining cloud sound speed enables a schematic picture for active galactic nuclei to be proposed. Seyfert galaxies and quasars are placed in the bubble regime. Variable compact radio sources reachmore » the cloud regime. Evolutionary paths are suggested and may provide an indirect test for this picture. « less
The Rise of TikTok during the Pandemic: Association between TikTok Consumption and Students’ Engagement

TikTok has been one of the most used Social Networking Services (SNS) worldwide. It has grown into a platform with a broad range of content, including sports, fashion, performing arts, and education, encouraging learners to join the community. In this, this descriptive-correlational aimed to determine the relationship between TikTok Utilization and the Level of Engagement of BPeA students of the City College of Angeles. After gathering data from 103 respondents through an online survey, the findings revealed that the BPeA students undergoing online classes use the TikTok application moderately and responsibly. Also, the level of students' engagement during online classes was found to be very high. Furthermore, a significant positive relationship was observed between TikTok utilization and students' engagement. Based on the findings, the researchers recommend that the Institute of Education, Arts, and Sciences (IEAS), in partnership with the College Guidance Office (CGO), collaborate on providing webinars or trainings on how SNS such as TikTok can be a helpful tool or distraction at the level of engagement of the students. Additionally, instructors/professors may also use the TikTok application as an educational tool to provide a better and more engaging classroom environment. Moreover, conducting the same study with the addition of other degree programs offered by the college to determine if the results may support or refute the findings is highly recommended. Lastly, other variables may be added to this present study to understand further the relationship between TikTok consumption and students' engagement.
Derivation and Solution of Harmonic Riccati Equations via Contraction Mapping Theorem

By the contraction mapping theorem and the harmonic Lyapunov equation theory, sufficient existence conditions of what we call the harmonic Riccati equations in finite-dimensional linear continuous-time periodic systems are explicated. Properties of the harmonic Riccati equations are also examined. Different from the Hamiltonian analysis, the approach reveals some analytic properties of periodic solutions of periodic matrix Riccati equations. An iterative algorithm is suggested for solving periodic matrix Riccati equations, which only involves algebraic Lyapunov equations and Fourier coefficients of periodically time-varying matrices.

Dynamic programming algorithms as quantum circuits: symmetric function realization

The work starts with a general idea of how to realize a dynamic programming algorithm as a quantum circuit. This realization is not tied to a specific design model, technology or a class of dynamic algorithms, it shows an approach for such synthesis. As an illustration of the efficiency of this approach, the class of all multiple-output symmetric functions is realized in a dynamic programming algorithm manner as a reversible circuit of Toffoli type elements (NOT, CNOT, and Toffoli gates). The garbage and quantum cost (found based on Barenco et al. paper) of the presented implementation are calculated and compared to the costs of previously described reversible synthesis methods. The summary of results of this comparison is as follows. The quantum cost of the proposed method is less than the quantum cost of any other reported systematic approach. The garbage is usually lower, except for comparison with the synthesis methods, whose primary goal is synthesis with theoretically minimal garbage. The presented algorithm application to the symmetric function synthesis results in circuits suitable for quantum technology realizations.
PHOTOMETRIC AND SPECTROSCOPIC OBSERVATIONS OF MV LYRAE FROM 1968 TO 1991

We report results of a program to monitor the peculiar variable star MV Lyr, carried out at Asiago since 1968. MV Lyrae is a cataclysmic variable formed by a white dwarf and an M5 V companion, with an orbital period near the 2-3 hr "period gap" and other unusual characteristics. The light curve shows that MV Lyr passes at times from its normal "high state" of maximum to a deep minimum (low state) in which it can remain for months or even years. The optical spectra of MV Lyrae at minimum are characterized by the presence of narrow emission lines of H, HeI, and very weak Ca II K. The same lines are observed in the course of outbursts, but the presence in this phase of He II 4686 indicates an increased degree of excitation. At maximum, He II 4686 disappears and some of the He I lines are found in absorption. The continuum rises toward the blue, like that of a blackbody with temperature of about 15000 degrees K. The color B-V is always negative, slightly higher at maximum (~ -0.2) than at minimum (~ -0.3). We compare with other typical members of the VY Sc1 sub-class of cataclysmic variables. MV Lyr, uniquely among these stars, remained in the low state for about ten years (1979 September - 1989 June). During this period of time MV Lyr was moderately active displaying several outbursts before returning to its high state.
Evaluation of (R)-[11C]PK11195 PET/MRI for Spinal Cord-Related Neuropathic Pain in Patients with Cervical Spinal Disorders

Activated microglia are involved in secondary injury after acute spinal cord injury (SCI) and in development of spinal cord-related neuropathic pain (NeP). The aim of the study was to assess expression of translocator protein 18 kDa (TSPO) as an indicator of microglial activation and to investigate visualization of the dynamics of activated microglia in the injured spinal cord using PET imaging with (R)-[11C]PK11195, a specific ligand for TSPO. In SCI chimeric animal models, TSPO was expressed mainly in activated microglia. Accumulation of (R)-[3H]PK11195 was confirmed in autoradiography and its dynamics in the injured spinal cord were visualized by (R)-[11C]PK11195 PET imaging in the acute phase after SCI. In clinical application of (R)-[11C]PK11195 PET/MRI of the cervical spinal cord in patients with NeP related to cervical disorders, uptake was found in cases up to 10 months after injury or surgery. No uptake could be visualized in the injured spinal cord in patients with chronic NeP at more than 1 year after injury or surgery, regardless of the degree of NeP. However, a positive correlation was found between standardized uptake value ratio and the severity of NeP, suggesting the potential of clinical application for objective evaluation of chronic NeP.
