Genomic Characterization of Antibiotic-Resistant Campylobacterales Isolated from Chilean Poultry Meat

Due to the lack of knowledge about Campylobacterales in the Chilean poultry industry, the objective of this research was to know the prevalence, resistance, and genotypes of Campylobacter, Arcobacter and Helicobacter in 382 samples of chicken meat purchased in Valdivia, Chile. The samples were analyzed using three isolation protocols. Resistance to four antibiotics was evaluated by phenotypic methods. Genomic analyses were performed on selected resistant strains to detect resistance determinants and their genotypes. A total of 59.2% of the samples were positive. Arcobacter butzleri (37.4%) was the most prevalent species, followed by Campylobacter jejuni (19.6%), C. coli (11.3%), A. cryaerophilus (3.7%) and A. skirrowii (1.3%). Helicobacter pullorum (14%) was detected by PCR in a subset of samples. Campylobacter jejuni was resistant to ciprofloxacin (37.3%) and tetracycline (20%), while C. coli and A. butzleri were resistant to ciprofloxacin (55.8% and 2.8%), erythromycin (16.3% and 0.7%) and tetracycline (4.7% and 2.8%), respectively. Molecular determinants were consistent with phenotypic resistance. The genotypes of C. jejuni (CC-21, CC-48, CC-49, CC-257, CC-353, CC-443, CC-446 and CC-658) and C. coli (CC-828) coincided with genotypes of Chilean clinical strains. These findings suggest that besides C. jejuni and C. coli, chicken meat could play a role in the transmission of other pathogenic and antibiotic-resistant Campylobacterales.
Determinant of Trade Balance: Empirical Study in ASEAN 5 Countries

International trade is a form of partnership and global activity of a country with other countries, traded from exports and imports. International trade activity is recorded in the trade balance for a certain period based on the value of the prevailing currency. It is one of the benchmarks for the success of an economy. This study examines the relationship between fundamental macroeconomic variables consisting of inflation, interest rates, imports, exchange rates, and GDP, which affect the trade balance performance in ASEAN-5 (Indonesia, Malaysia, Philippines, Singapore, and Thailand). The analytical method used is a regression with panel data from 2000-2019 with research objects from ASEAN-5 countries. The results of the analysis found that interest rates and imports had a significant adverse effect on the trade balance in ASEAN-5. GDP and exchange rates significantly positively affect the trade balance of ASEAN-5 countries. On the other hand, inflation has a negative effect but does not significantly affect the trade balance in ASEAN-5 countries.
An investigation into the nonlinear rheological behavior of modified asphalt binders using large amplitude oscillatory shear rheology

ABSTRACT Asphalt binders have been studied extensively with respect to their linear viscoelastic properties. From these properties, performance metrics have been derived and used for specification purposes. However, these materials are used in asphalt concrete pavements where they may experience time-dependent loads in the nonlinear regime. In the past, the vast majority of asphalt binders exhibited strong correlations between their linear and nonlinear properties and so despite this mismatch in characterization and the actual use phase domains, a system based on linear properties could be reliably deployed. More recently though, novel binders and additives have been introduced with differing relationships between linear and nonlinear behaviors. As such there is a need to characterize the asphalt binder response under large strains and use specifications that more explicitly account for the binder nonlinearity. Here, an attempt has been made to characterize the nonlinear rheological properties of asphalt binder using large amplitude oscillatory shear. The response of a single terminal blend, crumb rubber modified binder under large strains is analyzed using Lissajous-Bowditch plots while the contribution of higher harmonics is evaluated using Fourier-transform rheology. Finally, the elastic and viscous contributions are obtained using stress decomposition to an orthogonal set of Chebyshev polynomials. It is found that the relative nonlinearity increases with increasing strain and frequency under the tested conditions. The asphalt binder evaluated in this study predominantly exhibits shear thinning and either strain stiffening or softening behavior depending upon the test conditions. The applicability of time-temperature superposition in the nonlinear regime for asphalt binders is also evaluated.
Ultra-high sensitivity optical fiber Vernier photothermal sensor based on WTe2

In this paper, a novel Vernier photo-thermal optical fiber sensor based on WTe2 is proposed. The sensor is composed of a single-sided gold-plated silicon wafer and a single-mode optical fiber, and is encapsulated with a capillary tube. The air cavity and the silicon wafer cavity are cascaded to have an optical Vernier effect, and the sensitivity can be selected by adjusting the length of the air cavity. The ultra-high sensitivity of 2.53 nm mW−1 has been obtained through experiments, which has certain potential in the fields of optical imaging, detection, and sensing.
Development of a New Scheme for the Solution of Initial Value Problems in Ordinary Differential Equations

This paper is on the development of a new scheme for the solution of initial value problems in ordinary differential equations. We present some basic concepts and fundamental theories which are very vital to the development of the scheme. The new scheme is of order seven and its derivation is based on the representation of the theoretical solution by perturbed polynomial function of degree four. This scheme is suitable for problems associated with the systems of ordinary differential equations having oscillatory or exponential solution.
Molecular tunneling ionization of the carbonyl sulfide molecule by double-frequency phase-controlled laser fields

We have investigated the orientation-selective molecular tunneling ionization of carbonyl sulfide (OCS) molecules induced by linearly polarized double-frequency phase-controlled laser fields consisting of a fundamental and a second-harmonic light with a pulse duration of 130 fs and an intensity of 5 \ifmmode\times\else\texttimes\fi{} 10${}^{13}$ W/cm${}^{2}$. We performed simultaneous measurements using gas mixtures of OCS and carbon monoxide to calibrate the relative phase difference of the phase-controlled fields and to verify the mechanism of the tunnel ionization. It is demonstrated that there is a definite correlation between the orientation of ionized molecules and the structure of the highest occupied molecular orbital. We have discussed the experimental results by means of the weak field asymptotic theory. In addition, we have analyzed the quantum dynamics of photoelectrons in simultaneous ion-electron detection. The experimental results can be explained by a two-step model including the interaction with the parent ion. The recollision process plays a minor role for determining the preferable directions of polar molecules in the tunneling ionization at the experimental laser intensity used.
Net Benefit on E-Invoice Implementation: Applying the Delone & McLean Information Systems Success Model

E-Invoice is one of the preeminent products of E-Government. It is an application used to make electronic tax invoices and connected to an online website to report VAT. As a tax collection and reporting instrument, E-Invoice is believed to have escalated the government's capability of tax collection since it is more convenient, integrated, transparent, fast, effective, and efficient. It is cutting a lengthy tax administration procedure into a more comprehensive and efficient way. Therefore, the development and adoption of this system are crucial for various countries around the world. Hence, this study aims to analyze the success factor of E-Invoice using Delone and McLean's Information System Success Model. 121 samples were collected from respondents who are experienced in using the E-Invoice. SEM PLS method is used to analyze the data. The results show that the E-Invoice system is not fully integrated, thus affecting the outcome of user satisfaction. Overall, system quality and information quality affect intention to use significantly and positively, while service quality affects intention to use positively but not significantly. Then user satisfaction affects Net Benefit significantly and positively. In the end, the adoption of E-Invoice accelerates the processing of tax invoices and VAT reporting, providing convenience, effectiveness, and efficiency to users.
The first use of hypothermic machine perfusion in Korea to recover a procured kidney graft and prevent prolonged cold ischemic time: a case report

To overcome the shortage of donor grafts in kidney transplantation (KT), the use of marginal grafts has evolved. However, prolonged cold ischemic time (CIT) is especially critical when using marginal grafts. Recently, hypothermic machine perfusion (HMP) has been used to overcome the negative effects of prolonged CIT, and we report the first use of HMP in Korea. The donor was a 58-year-old man with severe hypoxia (PaO2 <60 mmHg, FiO2 100%) for 9 hours prior to procurement. The patient’s kidneys were the only organs accepted for transplantation, and both kidneys were assigned to Jeju National University Hospital. After procurement, the right kidney was preserved using HMP immediately, and the left kidney was directly transplanted into a patient with a CIT of 2 hours 31 minutes. The second operation was performed following the first, using the right kidney graft that had been preserved by HMP for 10 hours and 30 minutes. Although postoperative graft function gradually recovered in both patients, the serum creatinine level decreased faster in the HMP patient. Neither patient showed signs of delayed graft function, and both were discharged without significant complications. The short-term outcomes in this transplantation of mate kidney grafts demonstrated that graft function can be safely preserved using HMP, and that HMP is beneficial in overcoming the negative effects of prolonged CIT.
AN INTERVAL ESTIMATE FOR THE INTERCLASS CORRELATION IN BETA-BINOMIAL SAMPLING

The beta-binomial distribution has been frequently applied to model intraclass correlation among dichotomous responses in cluster sampling. To avoid using sophisticated numerical procedures to calculate maximum likelihood estimates, many authors have proposed different moment estimators. Most of them focused their discussion, however, on point estimation only. In this paper, we have developed a closed-form interval estimate for the intraclass correlation, and have shown it has asymptotically correct coverage. We have further used a Monte Carlo simulation to evaluate the performance of the proposed interval estimation in a variety of situations. We have found that when the number of clusters is moderate (>50), the proposed interval estimation performs reasonably well except for the situation where the intraclass correlation is large and the underlying mean response probability is small. Even when the number of clusters is as small as 20, the proposed interval estimation may still be useful in the situation where the intraclass correlation is small. We have also extended the proposed interval estimate to accommodate stratified sampling, in which each stratum has a different mean response probability but has a common intraclass correlation.
Scleral thickness in normal Indian eyes measured using spectral domain anterior segment optical coherence tomography

Purpose: To establish normative data on anterior scleral thickness using the spectral domain anterior segment optical coherence tomography (AS-OCT). Methods: In total, 200 eyes of 100 healthy subjects underwent AS-OCT scans in the temporal and nasal quadrants. The scleral + conjunctival complex thickness (SCT) was measured by a single examiner. Mean SCT was analyzed for differences across age groups, gender, and location (nasal versus temporal). Results: Mean age was 46.4 ± 18.3 (21–84) years; male to female ratio was 54:46. Mean SCT (nasal + temporal) of the right eye (RE) was 682.3 ± 64.2 μm in males and 660.6 ± 57.1 μm in females. In the left eye (LE), it was 684.6 ± 64.9 μm in males and 661.8 ± 49.3 μm in females. These differences between male and female for both eyes were statistically significant (P = 0.006 and P = 0.002). The mean SCT of temporal and nasal quadrants in the RE was 678.54 ± 57.50 and 666 ± 66.2 μm, respectively. In the LE, the temporal mean SCT quadrant was 679.6 ± 55.8 μm, and the nasal was 668.6 ± 63.6 μm. Age had a negative correlation with SCT (−0.62 μm/year; P = 0.03), and males had a higher temporal SCT than females (22 μm higher; P = 0.03). After adjusting for age and gender in a multivariate analysis, temporal SCT was significantly (P < 0.001) higher than nasal SCT. Conclusion: In our study, mean SCT decreased with age and males had a higher temporal SCT. This is the first study to evaluate scleral thickness in the Indian population, and the data can be used as a baseline for comparing variations in scleral thickness in disease.
Ultrahigh Carrier Mobility in Two-Dimensional IV–VI Semiconductors for Photocatalytic Water Splitting

Two-dimensional materials have been developed as novel photovoltaic and photocatalytic devices because of their excellent properties. In this work, four δ-IV–VI monolayers, GeS, GeSe, SiS and SiSe, are investigated as semiconductors with desirable bandgaps using the first-principles method. These δ-IV–VI monolayers exhibit exceptional toughness; in particular, the yield strength of the GeSe monolayer has no obvious deterioration at 30% strain. Interestingly, the GeSe monolayer also possesses ultrahigh electron mobility along the x direction of approximately 32,507 cm2·V−1·s−1, which is much higher than that of the other δ-IV–VI monolayers. Moreover, the calculated capacity for hydrogen evolution reaction of these δ-IV–VI monolayers further implies their potential for applications in photovoltaic and nano-devices.
Finite-time Stabilization of High-order Nonholonomic Systems with More General Nonlinear Drifts ⋆

This paper addresses the finite-time stabilization problem for a class of more general high-order nonholonomic systems with more general nonlinear drifts. , the upper bound of which involves not only state variables x1; · · · ;xi but also xi+1. By using finite-time Lyapunov stability theorem and adding a power integrator technique, a recursive controller design procedure is developed. Based on switching strategy to overcome the uncontrollability problem associated with x0(0) = 0, the uncertain closed-loop system is regulated to zero in a finite time. An illustrative example is provided to demonstrate the effectiveness of the proposed controller.
Quantitative Mineralogy of Planetary Silicate Ternary Mixtures Using Raman Spectroscopy

A 532‐nm‐excited lunar Raman spectrometer (LRS) has been selected as a scientific payload of the Chang'e‐7 mission, exploring mineralogy assemblages in the lunar south polar region. However, the quantification of dark‐colored silicate minerals via Raman spectroscopy is an urgent requirement for upcoming Raman applications in future lunar and planetary explorations. Therefore, we conducted detailed laboratory studies on the Raman quantification of lunar silicate minerals using ternary mixtures of feldspar, olivine, and augite. Quantitative models were established employing the observed linear relationship between Raman integrated intensities and mineral proportions. The significant correlation coefficients (>0.94) and small RMSE (≤4.20 wt.%) confirmed the performance of these models. A series of methods (multipoint sampling, multispectral averaging, peak area extraction, and spectral parameter ratios) were jointly used to ensure that the models were not significantly affected by crystal orientation, chemical inhomogeneity, and instruments. Factors (σ2/σ1) describing the relative Raman scattering cross sections were introduced to calibrate the Raman counts. Our results indicated that the relative Raman scattering efficiency of feldspar, olivine, and augite is 1.4:2.4:1, which can be used to improve the quantitative accuracy of the point‐counting method if polymineralic mixing spectra are dominant. The models were validated across different samples using laboratory mixtures and lunar soil (CE5C0600). The lithology of the Chang'e‐5 soils is basaltic/gabbroic according to the quantitative mineralogy returned from our models that is consistent with the results from traditional methods. This research will be of particular significance for accurately determining the mineral abundances for Chang'e‐7 and other planetary missions. As such, crucial information can be inferred to understand the geological evolution of the exploration regions.
A New Mathematical and Computational Framework for BVPs and IVPs in Solids, Fluids, Gases and their Interactions

Abstract : During this three year time period of the grant, five major areas listed under I-V have been investigated. Summary and conclusions resulting from this research, its impact and significance have been described at the end of each section in italics. Comments and in some cases, preliminary details, are also provided for future research. In each of the five major areas of research, model problems and their numerical solutions are presented to illustrate the features of the mathematical models and their applications. Computational mathematics frame for obtaining numerical solutions of the BVPs and IVPs in these areas is based on hpk finite element method with variationally consistent integral forms in which the space or space-time local approximations are in scalar product spaces. These spaces permit higher order global differentiability local approximations that are necessary to ensure integrals over the discretizations in the Riemann sense, so that when the integrated sum of squares of the residuals approaches zero for the whole discretization we are ensured that the GDEs are satisfied in the pointwise sense. Variationally consistent integral forms (in space or space-time) yield unconditionally stable computational processes for all BVPs and IVPs.
Engaging the Crowd in Sensing for Smart Mobility: A Discrete Choice Experiment

With rising numbers of people living in cities leading to increasing congestion and pollution, mobile crowdsensing applications form a potential solution to make transport systems smarter and more efficient. However, sharing data comes with the risk of private information being disclosed. Therefore, a clear incentive is necessary to motivate smart device users to share data about their activities and their environment. Taking a choice modelling approach, this study aims to identify factors related to incentives and privacy that explain choice behavior of users in crowdsensing applications. We find that the effort required by users is a main factor influencing the willingness to share data. 47% of respondents ( $\text{n}=$ 125) indicated to be highly concerned about their privacy. However, the risk of re-identification was found to be the least important factor to respondents, a finding which could be explained by the Privacy Paradox. Our findings imply that a trade-off has to be made by developers of crowdsensing applications between the richness of information on one hand, and the privacy risks and participation rate of users on the other hand. We propose three practical principles for designing effective and value-sensitive crowdsensing applications for smart mobility, which are 1) Tailor-made applications, 2) Transparency by design, and 3) Ensuring attractiveness of applications. Furthermore, our study provides a basis for further research on user preferences in smart mobility applications, which will become increasingly important in the light of current challenges in the field of mobility.
Understudied Hyperphosphatemia (Chronic Kidney Disease) Treatment Targets and New Biological Approaches

Hyperphosphatemia is a secondary disorder of chronic kidney disease that causes vascular calcifications and bone-mineral disorders. As per the US Centers for Disease Control and Prevention, renal damage requires first-priority medical attention for patients with COVID-19; according to a Johns Hopkins Medicine report, SARS-CoV-2 can cause renal damage. Therefore, addressing the research inputs required to manage hyperphosphatemia is currently in great demand. This review highlights research inputs, such as defects in the diagnosis of hyperphosphatemia, flaws in understanding the mechanisms associated with understudied tertiary toxicities, less cited adverse effects of phosphate binders that question their use in the market, socioeconomic challenges of renal treatment and public awareness regarding the management of a phosphate-controlled diet, novel biological approaches (synbiotics) to prevent hyperphosphatemia as safer strategies with potential additional health benefits, and future functional food formulations to enhance the quality of life. We have not only introduced our contributions to emphasise the hidden aspects and research gaps in comprehending hyperphosphatemia but also suggested new research areas to strengthen approaches to prevent hyperphosphatemia in the near future.
Clinical Application of a Multiplex Droplet Digital PCR in the Rapid Diagnosis of Children with Suspected Bloodstream Infections

Droplet digital PCR (ddPCR) recently has been shown to be a potential diagnostic tool for adults with bloodstream infections (BSIs); however, its application in children remains obscure. In this study, 76 blood samples of children with suspected BSIs were synchronously detected by traditional blood cultures (BCs) and ddPCRs. Our team validated the diagnostic performance of ddPCR including sensitivity, specificity, and positive and negative predictive values. The 76 pediatric patients from the hematology department (67.1%), the pediatric intensive care unit (PICU, 27.6%), and other departments (5.2%) were enrolled. The positive rate of ddPCR results was 47.9%, whereas that for BC was 6.6%. In addition, the time consumption of ddPCR was shorter, only for 4.7 ± 0.9 h, in comparison with the detection timing of BC (76.7 ± 10.4 h, p < 0.01). The levels of agreement and disagreement between BC and ddPCR were 96.1% and 4.2%, and the negative agreement reached 95.6%. The sensitivity of ddPCR was 100%, with corresponding specificities ranging from 95.3 to 100.0%. In addition, a total of nine viruses were identified by ddPCR. In China, the multiplexed ddPCR first could be a tool for the rapid and accurate diagnosis of children with suspected BSIs and can be an early indicator of the possibility of viraemia in children with immunosuppression.
