How Comparable Are the Jackknife and Bootstrap Results: An Investigation for a Case of Canonical Correlation Analysis.

The jackknife and bootstrap methods are becoming more popular in research. Although the two approaches have similar goals and employ similar strategies, information is lacking with regard to the comparability of their results. This study systematically investigate,1 the issue for a canonical correlation analysis, using data from four random samples from the National Education Longitudinal Study of 1988. Some conspicuous discrepancies are observed mainly under small sample size conditions, and this raises some concern when researchers need to choose between the two for their small samples. Due to the lack of theoretical sampling distributions in canonical analysis, it is unclear which method had superior performance. It is suggested that Monte Carlo simulation is needed for this kind of comparison. It is also suggested that caution is warranted in generalizing the results to other statistical techniques, since the validity of such generalizations is uncertain.

Prevalence and Molecular Characterization of Extended-Spectrum β-Lactamases and AmpC β-lactamase-Producing Enterobacteriaceae among Human, Cattle, and Poultry

Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae are a universal public health alarm frequently identified among humans, animals, and poultry. Livestock and poultry production are a possible source of multidrug-resistant microorganisms, including ESBL-producing Enterobacteriaceae, which confer antimicrobial resistance to different β-lactam antimicrobial agents. From January to May 2020, a cross-sectional study was carried out in three dairy cattle farms and four poultry farms in different districts of northern Egypt to assess the prevalence of ESBLs, AmpC beta-lactamase-producing E. coli and Klebsiella in livestock, poultry, and human contacts, and to investigate the genetic relatedness of the recovered isolates. In total, 140 samples were collected, including human fecal samples (n = 20) of workers with intimate livestock contact, cattle rectal swabs (n = 34), milk (n = 14), milking machine swabs (n = 8), rations (n = 2), and water (n = 2) from different cattle farms, as well as cloacal swabs (n = 45), rations (n = 5), water (n = 5) and litter (n = 5) from poultry farms. The specimens were investigated for ESBL-producing E. coli and Klebsiella using HiCrome ESBL media agar. The agar disk diffusion method characterized the isolated strains for their phenotypic antimicrobial susceptibility. The prevalence of ESBL-producing Enterobacteriaceae was 30.0%, 20.0%, and 25.0% in humans, cattle, and poultry, respectively. Further genotypic characterization was performed using conventional and multiplex PCR assays for the molecular identification of ESBL and AmpC genes. The majority of the ESBL-producing Enterobacteriaceae showed a multi-drug resistant phenotype. Additionally, blaSHV was the predominant ESBL genotype (n = 31; 93.94%), and was mainly identified in humans (n = 6), cattle (n = 11), and poultry (14); its existence in various reservoirs is a concern, and highlights the necessity of the development of definite control strategies to limit the abuse of antimicrobial agents.
Topical Agents for Nonrestorative Management of Dental Erosion: A Narrative Review

A nonrestorative approach to the management of dental erosion is the foremost option: controlling dental erosion. The objectives of this study are to provide an overview and to summarise the effects and properties of topical anti-erosive agents as a nonrestorative treatment of dental erosion. A literature search was conducted on five databases of peer-reviewed literature—Cochrane Library, EMBASE, PubMed, Scopus and Web of Science—to recruit articles published between 1 January 2000 and 31 December 2021. The literature search identified 812 studies; 95 studies were included. Topical anti-erosive agents can be broadly categorised as fluorides, calcium phosphate-based agents, organic compounds and other anti-erosive agents. In the presence of saliva, fluorides promote the formation of fluorapatite on teeth through remineralisation. Calcium phosphate-based agents supply the necessary minerals that are lost due to the acid challenge of erosion. Some organic compounds and other anti-erosive agents prevent or control dental erosion by forming a protective layer on the tooth surface, by modifying salivary pellicle or by inhibiting the proteolytic activity of dentine collagenases. Topical anti-erosive agents are promising in managing dental erosion. However, current evidence shows inconsistent or limited results for supporting the use of these agents in clinical settings.
Detection of Nipah and Hendra Viruses Using Recombinant Human Ephrin B2 Capture Virus in Immunoassays

Nipah virus (NiV) and Hendra virus (HeV) are classified as high-consequence zoonotic viruses characterized by high pathogenicity and high mortality in animals and humans. Rapid diagnosis is essential to containing the outbreak. In this study, the henipavirus receptor ephrin B2 was examined to determine whether it could be used as a universal ligand for henipavirus detection in immunoassays. Enzyme-linked immunosorbent assays (ELISAs) were developed using recombinant ephrin B2 as the capture ligand and two monoclonal antibodies (mAbs) as detection reagents. Using mAb F27NiV-34, which cross-reacts with NiV and HeV, we were able to detect NiV and HeV, while mAb F20NiV-65 was used to detect NiV. Therefore, using these two ELISAs, we were able to differentiate between NiV and HeV. Furthermore, we developed a rapid lateral flow strip test for NiV detection using ephrin B2 as the capture ligand combined with mAb F20NiV-65 as the detector. Taken together, our results show that the combination of ephrin B2 and a specific mAb provides an excellent pairing for NiV and HeV detection.
Crosscorrelation kernel in the Green function retrieval and time reversal acoustics

Crosscorrelation structures in the Green function retrieval by crosscorrelating wavefields are revealed using rigorous mathematical theory on integral equations. The previous practice on extracting the Green function by crosscorrelating the wavefields recorded at two locations produced by the same source and then summing such crosscorrelations over all sources on a boundary is inadequate and has limitations in recovering the low frequency content in the Green function. To recover the exact Green function, we need crosscorrelate the wavefields observed at the two locations generated by different sources, respectively. The crosscorrelation structure can be viewed as a matrix in the discrete case or an integral operator in the continuous case. The previous Green function retrieval method corresponds to the identity matrix multiplying a constant. If the matrix is diagonal, the wavefield crosscorrelation is still within the wavefield due to the same source but different weighting should be applied for different sources. We have derived analytically the crosscorrelation kernels for two important cases, the plane boundary and the circular boundary, and both kernels are symmetrical difference kernels, which correspond to convolutional operations. For high frequency waves or far-field sources, the kernels reduce to the know result which is the Dirac delta distribution (or an identity matrix). For other boundaries of general geometric shapes, numerical schemes like the boundary element method can be used to solve for the kernel matrix.
Designing a Fuzzy Q-Learning Power Energy System Using Reinforcement Learning

Modern power and energy systems are becoming more complicated and uncertain as distributed energy resources (DERs), flexible loads, and other developing technologies become more integrated. This brings great challenges to the operation and control. Furthermore, the deployment of modern sensor and smart metres generates a considerable amount of data, which opens the door to fresh data-driven ways for dealing with complex operation and control difficulties. One of the most commonly touted strategies for control and optimization problems is reinforcement learning (RL). Designing a fuzzy Q-learning power energy system using RL technique will control and reduce the problems arranging in the energy system.
Association of fear assessment in inflammatory rheumatic diseases (FAIR) questionnaire with ankylosing spondylitis quality of life and disease activity in patients with ankylosing spondylitis

Background/Aim: Fear against disease course, treatment, and limitations in family, work, and social life are commonly seen but mostly overlooked by physicians of patients with chronic inflammatory rheumatic diseases. Ankylosing spondylitis (AS) is a chronic inflammatory disease in young adults characterized by limitations in spinal mobility. The Fear Assessment (FAIR) Questionnaire was designed especially for patients with rheumatoid arthritis and spondyloarthritis to assess the level of fear from the patient’s perspective. Here we evaluate the FAIR score in AS patients and its association with disease activity, AS quality of life (ASQoL), depression, anxiety, and fatigue levels. Methods: This cross-sectional study included 79 patients with AS, and disease activity was assessed by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), AS-Disease Activity Score-C reactive protein, and functional status was assessed by Bath Ankylosing Spondylitis Functional Index (BASFI). Patient global assessment of disease and pain were scored on 0–10 cm visual analog scores. All patients completed FAIR and ASQoL questionnaires. The depression and anxiety were evaluated by Hospital Anxiety and Depression Scale (HADS), and fatigue was assessed by Fatigue Severity Scale (FSS). Results: The mean age of AS patients (62% male) was 41.7 (11.3) years. Most of the patients were on biological disease-modifying anti-rheumatic drugs (bDMARDs). The patients’ median BASDAI, ASDAS-CRP, and BASFI were 5.4 (range, 3.8–7.4), 3.83 (1.4), and 4.0 (range, 2.3–6.2), respectively. The overall FAIR, ASQoL, FSS, HADS-depression, and HADS-anxiety scores were 75 (range, 52–91), 9.6 (5.2), 5.4 (range, 4.1–7), 7.7 (4.4) and 9.6 (5.2), respectively. There were statistically significant correlations between disease activity indices and FAIR, ASQoL, FSS, and HADS scores. The FAIR scores significantly correlated with ASQoL, FSS, and HADS scores. The patients with active disease (BASDAI ≥ 4) had significantly higher levels of FAIR, ASQoL, FSS, and HADS. The best cut-off value for the FAIR score of AS patients with moderate to severe disease activity was 50 (AUC: 0.734, 95% CI [0.599–0.870], P = 0.002), with a sensitivity of 89.8%, specificity of 55%, positive likelihood ratio of 1.99, and Youden index of 0.45. Conclusion: This study shows that AS patients face a high level of fear which is associated with higher disease activity, higher risk of mood disorders, and lower quality of life. Physicians should not only focus on the physical improvement of the patient but also handle the fear of patients against their diseases and their treatment. This holistic approach will improve the dialogue between the physician and the patient, which will result in increased compliance with treatment and will raise the quality of care.
Language Policy as a Focal Point in English-Medium International Schools

A language policy in an international school is a document that should state how language will be taught, learned, and used. In essence, a language policy can provide organization and cohesion for an international school as it works to deliver a curriculum to the students, and many students enrolled in international schools are English language learners (ELLs). This quantitative survey-based study aimed to investigate teacher adherence and knowledge of language policy in English-medium international schools. Also explored was the provision of professional development for working with ELLs and teacher self-efficacy when teaching ELLs in relation to language policy knowledge. Compared to previously reported data, key findings showed a rise in the percentage of teachers reporting their school had a language policy and a lower percentage of teachers reporting they were consistently following the policy. Additional findings were that less than half of the participants reported their school provided a medium or higher frequency of professional development for working with ELLs, and teachers who had knowledge of the language policy had higher self-efficacy levels when teaching ELLs than teachers who had no knowledge of a language policy.
Fast Random Projections Using Lean Walsh Transforms

Abstract : We present a kappa x d random projection matrix that is applicable to vectors x belongs to R(exp d) in O(d) operations if d greater than or equal to k(exp 2 + delta-prime) . Here, kappa is the minimal Johnson Lindenstrauss dimension and delta is arbitrarily small. The projection succeeds, with probability 1-1/n, in preserving vector lengths, up to distortion epsilon, for all vectors such that || x ||(sub infinity) less than or equal to || x ||(sub 2)k(exp -1/2)d(exp -delta) (for arbitrary small delta). Sampling based approaches are either not applicable in linear time or require a bound on || x ||(sub infinity) that is strongly dependant on d. Our method overcomes these shortcomings by rapidly applying dense tensor power matrices to incoming vectors.
Azimuth, Energy, Q, and Temperature: Variations on P Wave Amplitudes in the United States (Paper 3R1817)

Mean relative P wave (1 s) amplitude characteristics are determined for standardized seismic stations in the United States. Data are compiled from three azimuths: to the north, explosions in Russia; to the northwest, earthquakes along the Asian-Pacific arc; and to the south-southeast, earthquakes in South America. Characteristic receiver amplitudes are found to be azimuthally dependent. High-amplitude areas occur in the central United States, and lowest amplitudes occur along the Rocky Mountain front range and the Rio Grande rift zone. Amplification effects of low-velocity sediments are significant in the central United States. Azimuthal amplitude variations in the eastern United States are consistent with an anomalous attenuating or defocusing body in the lower mantle beneath Colombia, South America. Nonazimuthal amplitude studies are tied to the azimuthal data set to increase station amplitude coverage. The regional and local stability of amplitudes is analyzed. Amplitudes are stable with an average variation of a factor of about 1.3 around the regional mean. For seismic stations situated on hard bedrock, the squared amplitude variations are related to energy variations in the P wave fronts. Acknowledging the likely importance of elastic focusing/defocusing and scattering effects at individual stations, variations of anelastic attenuation are derived that are consistent with the observed energy-amplitude variations. Assuming that the variations of anelastic attenuation occur in the upper 400 km of the earth, high-amplitude stations may be unattenuated, low-amplitude stations are consistent with Q ∼ 110, and a mean amplitude implies Q ∼ 220–240. The range of variation of Q is mapped into temperature variations, assuming a thermally activated Q mechanism and an olivine activation energy for the upper mantle. The apparent Q variations are consistent with temperature variations of 135°–287°C between high- and low-amplitude seismic station sites. Geophysical and physiographic correlations with the P wave amplitude variations are discussed. Accounting for the motion of the North American plate, low P wave amplitudes along the Rocky Mountain front may be related to the uplift of the Colorado Plateau. Low amplitudes extending from northern Texas to New England lie along the approximate boundary of the continental craton.
Spectrum of Rare and Common Genetic Variants in Arrhythmogenic Cardiomyopathy Patients

Arrhythmogenic cardiomyopathy (ACM) is a rare inherited disorder, whose genetic cause is elusive in about 50–70% of cases. ACM presents a variable disease course which could be influenced by genetics. We performed next-generation sequencing on a panel of 174 genes associated with inherited cardiovascular diseases on 82 ACM probands (i) to describe and classify the pathogenicity of rare variants according to the American College of Medical Genetics and Genomics both for ACM-associated genes and for genes linked to other cardiovascular genetic conditions; (ii) to assess, for the first time, the impact of common variants on the ACM clinical disease severity by genotype-phenotype correlation and survival analysis. We identified 15 (likely) pathogenic variants and 66 variants of uncertain significance in ACM-genes and 4 high-impact variants in genes never associated with ACM (ABCC9, APOB, DPP6, MIB1), which deserve future consideration. In addition, we found 69 significant genotype-phenotype associations between common variants and clinical parameters. Arrhythmia-associated polymorphisms resulted in an increased risk of arrhythmic events during patients’ follow-up. The description of the genetic framework of our population and the observed genotype-phenotype correlation constitutes the starting point to address the current lack of knowledge in the genetics of ACM.
Evaluation of Serum Omentin-1, Vaspin, Leptin, Adiponectin Levels in Obese/Overweight Children and Their Relationship With Non-Alcoholic Fatty Liver Disease

To investigate adipokines (vaspin, omentin-1, adiponectin and leptin) and their correlation with hepatosteatosis degree in obese/overweight (O/O) children. We analyzed adipokine levels of 81 children (49 O/O, [body mass index (BMI) > 95th] and 32 non-obese (BMI = 5-85th) admitted to the pediatric outpatient clinic. Serum triglyceride, glucose, low density lipoprotein-cholesterol, total cholesterol, high density lipoprotein-cholesterol, alanine aminotransferase, aspartate aminotransferase (AST), insulin, HbA1c levels and leptin, omentin-1, vaspin, adiponectin levels were studied. O/O children with hepatosteatosis were divided into grades 1, 2 and 3 according to the degree of hepatosteatosis determined by ultrasonography. While AST (p = 0.001), triglyceride (p = 0.006), BMI percentile (p = 0.000), HOMA index (p = 0.002), systolic blood pressure (p = 0.02), leptin (p = 0.001), omentin-1 (p = 0.001), adiponectin (p = 0.001) levels were higher, vaspin level was lower (p = 0.008) in the (O/O) group compared to the controls. There was a positive correlation between HDL and vaspin, and a negative correlation between HDL and omentin-1 in the O/O group. Also it was observed that as the degree of hepatosteotosis increased, leptin (p = 0.004), omentin-1 (p = 0.001) levels were increased. There was no significant change in vaspin level (p = 0.128). The high levels of omentin-1, leptin and adiponectin have an association with the development of hepatosteatosis in O/O children.
Saffman-Taylor Problem for a Non-Newtonian Fluid

We study the linear stability of a steady displacement of an Oldroyd-B fluid by air in a Hele- Shaw cell. We obtain the perturbations equations from the full basic flow equations and we perform a depth-average procedure (across the Hele-Shaw gap) in the dynamic boundary condition at the interface. The new element is an exact formula of the growth rate (in time) of perturbations, obtained in the range of small Deborahnumbers which appear in the constitutive relations. If the Deborahnumbers are equal, then our growth rate is quite similar to the Saffman-Taylor formula for a Newtonian liquid displaced by air. We prove the destabilizing effect of the elasticity properties of the Oldroyd-B fluid, in agreement with some previous numerical results is this field.
Development of an Immunochromatographic Test Based on Rhoptry Protein 14 for Serological Detection of Toxoplasma gondii Infection in Swine

Simple Summary Toxoplasmosis is one of the most common parasitic zoonoses in the world. It not only threatens human health and safety but also causes considerable losses to the global animal husbandry industry. Swine, as an intermediate host of Toxoplasma gondii, has important economic and public health significance, and the global prevalence of T. gondii in swine varies between 10% and 60%. Therefore, it is important to establish simple, effective, sensitive and specific diagnostic methods for the detection and prevention of T. gondii infection in swine. In the present study, we developed a colloidal gold immunochromatographic strip based on rTgROP14, recombinant protein A and monoclonal antibody TgROP14-5D5 for serological detection of T. gondii in swine populations. This new ICT achieved good specificity and sensitivity and has potential for routine serological detection of T. gondii in swine. Abstract Toxoplasma gondii, a worldwide distributed apicomplexan protozoan, can infect almost all warm-blooded animals and may cause toxoplasmosis. In order to provide a point-of-care detection method for T. gondii infection, an immunochromatographic test (ICT) was established. The proposed test uses recombinant T. gondii rhoptry protein 14 (ROP14) conjugated with 20 nm gold particles, recombinant protein A as the detection line and monoclonal antibody TgROP14-5D5 as the control line. The specificity, sensitivity, positive predictive value, negative predictive value and stability of this new ICT were evaluated. rTgROP14 was specifically recognized by positive serum of T. gondii but not negative serum. mAb TgROP14-5D5 showed higher specific recognition of T. gondii antigens and was therefore selected for subsequent colloidal gold strip construction. The new ICT based on TgROP14 exhibited good diagnostic performance with high specificity (86.9%) and sensitivity (90.9%) using IHA as a “reference standard”. Among 436 field porcine sera, ICT and IHA detected 134 (30.7%) and 99 (22.7%) positive samples, respectively. The relative agreement was 87.8%. These data indicate that this new ICT based on TgROP14 is a suitable candidate for routine testing of T. gondii in the field.
