Band-edge absorption characteristics of semi-insulating indium phosphide under unified Franz-Keldysh and Einstein models

The foundational Franz-Keldysh effect and Einstein model are applied in this work to characterize semiconductor band-edge absorption—and its departures from ideality. We unify the Franz-Keldysh and Einstein models to fully characterize the ﬁeld-induced tunneling of photoexcited electrons from degenerate valence bands into the conduction band, with encroachment into the band gap arising as an Urbach tail. Our uniﬁed model is implemented for semi-insulating indium phosphide (SI-InP) with strong agreement seen between the theoretical and experimental results for varied photon energies and electric ﬁelds.
Creativity on Student Learning Outcomes in Al-Quran Hadith Subjects

The purpose of this study was to analyze the effect of learning creativity on student learning outcomes in Al-Quran Hadith subjects at Madrasah Tsanawiyah Nurul Yaqin Pekanbaru. This research is a quantitative research by testing hypotheses or solving problems on the basis of theoretical deduction, with measurements using statistical data. This research was conducted at Madrasah Tsanawiyah (MTs) Nurul Yaqin Pekanbaru with a population of 350 people. The sampling technique used in this research is proportional stratified random sampling. The total number of sample population is known to have a set precision of 5%, then the number of samples in this study is 175 students. The data collection techniques in this study were questionnaires, tests and documentation. The data analysis technique in this study can be divided into three major stages, namely 1) Research Instrument Test Phase (Questionnaire/Questionnaire), 2) Classical Assumption Test Phase (Test Data before being analyzed by Parametric analysis), and 3) Research Hypothesis Testing Phase ( Statistical test to test the research hypothesis). Based on the results of research on the effect of learning creativity on student learning outcomes in the subjects of Al-Qur'an Hadith at MTs Nurul Yaqin Pekanbaru, which is associated with theory, it can be concluded that learning creativity (X) with student learning outcomes (Y) obtained tcount of 4.320 while ttable with a significance level of 5% and degrees of freedom (dk) = nk = 175–2 = 173 is 1.960. In this case, tcount (4,320) ttable (1,960), so that it is obtained in the area where Ho is accepted (Ha is accepted, Ho is rejected). In addition, from the table above, it can be seen that the probability value is 0.006, which means this number is smaller than the significance level (0.006 0.05), meaning that it can be concluded that the variable of learning creativity has a positive and significant influence on student learning outcomes
Bacterial and Fungal Profile, Antibiotic Susceptibility Patterns of Bacterial Pathogens and Associated Risk Factors of Urinary Tract Infection Among Symptomatic Pediatrics Patients Attending St. Paul’s Hospital Millennium Medical College: A Cross-Sectional Study

Background Urinary tract infection is a common infection in pediatrics. Understanding the common etiology of urinary tract infections, their antimicrobial susceptibility pattern, and associated risk factors in a particular setting can provide evidence for the appropriate treatment of the cases. Purpose The current study is aimed to determine the common etiology and prevalence of uropathogens associated with urinary tract infection, as well as the antibiotic susceptibility profile of bacterial isolates, and to identify risk factors associated with urinary tract infection among pediatric patients. Materials and Methods The study was conducted at St. Paul Hospital Millennium Medical College between October 2019 and July 2020. Urine was collected aseptically from patients, inoculated onto culture media, and incubated at 37 °C for 18–48 hours. Bacteria and yeast were identified following standard procedures. Antibiotic susceptibility testing of bacterial pathogens was carried out by the Kirby Bauer disc diffusion method. Descriptive statistics and logistical regressions were used to estimate the crude ratio with a 95% confidence interval. P-value < 0.05 was considered significant. Results Significant bacterial/fungal growth was observed in 65 samples giving a prevalence of 28.6% of which 75.4% (49/65) and 24.6% (16/65) were bacterial and fungal pathogens, respectively. About 79.6% of bacterial etiology were Escherichia coli and Klebsiella pneumoniae. The highest resistance was observed against ampicillin (100%), cefazolin (92.1%), and trimethoprim-sulfamethoxazole (84.1%), both of which are commonly used for empirical treatment in Ethiopia. Length of hospital stay (P=0.01) and catheterization (P=0.04) were statistically associated with urinary tract infection. Conclusion The high prevalence of urinary tract infection was observed in our study. Enterobacteriaceae were the major cause of urinary tract infection. Length of hospital stay and catheterization were significantly associated with urinary tract infection. Both Gram-negative and Gram-positive bacteria were extremely resistant to ampicillin and trimethoprim-sulfamethoxazole.

Determinants of Antibody Response to a Third SARS-CoV-2 mRNA Vaccine Dose in Solid Organ Transplant Recipients: Results from the Prospective Cohort Study COVAC-Tx

Background: We studied factors related to humoral response in solid organ transplant (SOT) recipients following a three-dose regimen of an mRNA-based SARS-CoV-2 vaccine. Method: This was a prospective study of SOT recipients who received a third homologous dose of the BNT162b2 (Pfizer–BioNTech) vaccine. The anti-spike S1 IgG response was measured using the SARS-CoV-2 IgG II Quant assay (Abbott Laboratories) with a cut-off of 7.1 BAU/mL. Multiple logistic regression was used to determine the factors associated with humoral response. Results: In total, 395 SOT recipients were included. Anti-spike IgG was detected in 195/395 (49.4%) patients after the second dose and 261/335 (77.9%) patients after the third dose. The overall mean increase in antibody concentration after the third dose was 831.0 BAU/mL (95% confidence interval (CI) 687.4–974.5) and 159 (47.5%) participants had at least a 10-fold increase in antibody concentration after the third dose. The increase in antibody concentration was significantly higher among patients with detectable antibodies after the second dose than those without. Cumulative time from transplantation and liver recipients was positively associated with an antibody response, whereas older age, administration of prednisolone, and proliferation inhibitors were associated with diminished antibody response. Conclusion: Although the third dose of the BNT162b2 vaccine improved humoral responses among SOT non-responders following the second dose, the overall response remained low, and 22.1% did not develop any response. Patients at risk of a diminished vaccine response require repeated booster doses and alternative treatment approaches.
Quantitative Measurement Techniques for Wind Turbine Blade Aerodynamic Performance

The installed capacity of wind turbines has been growing rapidly in recent years, creating an increased need for accurate measurements and models of wind turbine performance to further their development. There is a need in the literature for experimental data to validate theoretical models and guide turbine blade design. Two related projects were completed to develop measurement techniques and provide such data: the use of a fivehole probe and in-blade data acquisition system to measure the wind turbine blade angle of attack, and the use of tuft flow visualization and a digital image processing algorithm to quantitatively assess the flow direction and behaviour of a wind turbine blade. Experiments were completed at the University of Waterloo Wind Generation Research Facility using a 3.3 m diameter test turbine. Wind speed, rotational speed, shaft torque and angular position were controlled or monitored throughout all experiments. A 3D printed test blade was equipped with a five-hole pressure probe and data acquisition system to measure the flow angles at various radial locations. For tuft flow visualization testing, a separate rotor consisting of three aerodynamic blades was installed, and tufts and a camera were mounted to the surface of one of the blades. Extensive software was developed for controlling instruments and collecting experimental data. The angle of attack and span-wise flow angles were successfully measured as a function of the tip speed ratio, yaw-offset position, radial location and azimuthal position. Variations in the angle of attack with these variables were consistent with wind turbine aerodynamics theory, and results were in close agreement with results calculated using two separate models from the literature. Angle of attack values typically ranged from 7◦ to 25◦ throughout the tests, with fluctuations as high as 7◦ when the wind turbine was yawed. Uncertainty values in the measurements were typically found to be within ±0.2◦, which shows great potential for the method. Tuft flow visualization measurements were processed by logging the orientation of each individual tuft, calculating their average orientations and interpolating to develop a contour map of flow direction over the wind turbine blade as a function of tip speed ratio, yawposition and azimuthal position. Throughout testing, the fraction of tufts indicating stall ranged from 25% to as high as 60% as the tip speed ratio was decreased. Contour maps showed that separation typically formed first on the trailing edge of the blade near the root, and expanded towards the leading edge and tip. This pattern is in agreement with trends found for similar blades in the literature.
Computation of wheel–rail contact force for non-mapping wheel–rail profile of Translohr tram

ABSTRACT Translohr tram has steel wheels, in V-like arrangements, as guide wheels. These operate over the guide rails in inverted-V arrangements. However, the horizontal and vertical coordinates of the guide wheels and guide rails are not always mapped one-to-one. In this study, a simplified elastic method is proposed in order to calculate the contact points between the wheels and the rails. By transforming the coordinates, the non-mapping geometric relationship between wheel and rail is converted into a mapping relationship. Considering the Translohr tram’s multi-point contact between the guide wheel and the guide rail, the elastic-contact hypothesis take into account the existence of contact patches between the bodies, and the location of the contact points is calculated using a simplified elastic method. In order to speed up the calculation, a multi-dimensional contact table is generated, enabling the use of simulation for Translohr tram running on curvatures with different radii.
Interaction between Single Nucleotide Polymorphisms (SNP) of Tumor Necrosis Factor-Alpha (TNF-α) Gene and Plasma Arsenic and the Effect on Estimated Glomerular Filtration Rate (eGFR)

When poisons enter the human body, tumor necrosis factor (TNF-α) will increase and cause damage to tissues through oxidative stress or inflammatory reaction. In previous studies, arsenic (As) has known to cause many health problems. Some studies have shown that As exposure is negatively correlated with estimated glomerular filtration rate (eGFR), or with the prevalence of proteinuria. At present, there are few studies focusing on the effects of As exposure and TNF-α single nucleotide polymorphism (SNP) to eGFR; thus, this study was intended to explore the interactions between TNF-α SNPs and plasma As and their effects on eGFR. A cohort of 500 adults, aged 30 to 70 years, was randomly selected from Taiwan Biobank (TWB). We used the gene chip to screen out seven SNPs of the TNF-α gene and used the results, combined with questionnaires, biochemical tests, and stored plasma samples from the TWB, for the analysis of As by inductively coupled plasma mass spectrometry (ICP-MS). After adjustments for BMI, hypertension, hyperlipidemia, kidney stones, and smoking habits, multiple regression statistics were performed to explore the interaction between SNPs and plasma As with eGFR. In this sample of the general population, plasma As had a significant association with the decline of eGFR (β (SE) = −7.92 (1.70), p < 0.0001). TNF-α gene SNP rs1800629 had the property of regulating TNF-α, which interacts with plasma As; individuals with the AG type had a significantly lower eGFR than those with the GG type, by 9.59 mL/min/1.73 m2 (p < 0.05), which, regarding the dominant model, could infer that the A allele is a risk allele. SNP rs769177 had no interaction with plasma As; however, participants with the TT or TC type had significantly higher eGFR levels than the CC carriers, by 4.02 mL/min/1.73 m2 (p < 0.05). While rs769176 interacted with plasma As, if a person with the TC type had a higher plasma As concentration, that would sustain higher eGFR. This study found that certain SNPs of the TNF-α gene would be robust to the decline of eGFR caused by As exposure. Still, we need further research to confirm the protective regulation mechanism of these SNPs.
Public Negative Labeling Effects on Team Interaction and Performance

Across four studies, we examine how public negative labeling, which is when a group member is publicly identified as bad, affects team performance. Across three experiments and one field study, we test and find support for our model, that public negative labeling undermines team performance via reduced perceptions of team interaction quality. Our study contributes to the expansive conversation on team effectiveness which highlights that “fighting fire with fire” in terms of public negative labeling is ineffective for dealing with uncivil workplace behavior.
Aspects of Non-Dipping Blood Pressure Variations in Juvenile, Middle-Aged, And Adult Kazakhs

Juvenile, middle-aged, and elderly Kazakhs have been found to exhibit non-dipping blood pressure variations (BPV). Such variations are seen more often in middle-aged and elderly Kazakhs than in juvenile Kazakhs. The purpose of this study was to determine whether non-dipping BPV become more common in Kazakhs with advancing age and to compare the characteristics of non-dipper and dippers in order to clarify the effects of ageing on non-dipping type BPV. We performed ambulatory blood pressure monitoring. Juvenile, middle-aged, and elderly Kazakhs were enrolled. Each age group was further divided into those with dipping and non-dipping type BPV. We analyzed systolic blood pressure (SBP) variations with the maximum entropy method (MEM). Dippers and non-dippers accounted for 81% and 19% of the juvenile Kazakhs, 48% and 52% of the middle-aged Kazakhs, and 28% and 72% of the elderly Kazakhs, respectively. MEM analysis revealed that among the middle-aged and elderly Kazakhs the SBP variations of the non-dippers exhibited a 24-hour periodicity with a weak power spectral density as well as an ultradian periodicity. These features may have contributed to the generation of a decreased circadian rhythm in SBP, and thus, ultimately led to the non-dipping SBP variations observed in the middle-aged and elderly non-dipping Kazakhs. The non-dipping type BPV may have resulted from an effect of aging in Kazakhs since non-dipping BPV variations were more common in middle-aged and elderly Kazakhs than in juvenile Kazakhs.
Revenue standard and earnings management during the COVID-19 pandemic: A comparison between IFRS and GAAP

International Financial Reporting Standards 15 — Revenue from Contracts with Customers (IFRS 15) was issued to inhibit the use of revenues for earnings management purposes. During COVID-19, the standard was used to manage earnings (Lopatta, Alexander, Gastone, & Tammen, 2020). This study aims to explain earnings management practices by using a revenue standard. An online questionnaire was distributed by Momentive Inc. (formerly SurveyMonkey Inc.) to accountants working in two different contexts: Jordan as an IFRS country and the USA as a Generally Accepted Accounting Principles (GAAP) country. A convenience sample of 304 questionnaires from both countries was valid for analysis. The findings of ordinary least square (OLS) regression suggest that, during COVID-19, both users used the revenue standard as a tool to manage earnings. In addition, IFRS users were more conservative than GAAP users in terms of existing contracts, while both of them were the same in terms of future contracts. The results should help policymakers and regulators to rethink the flexibility given to managers in dealing with revenue contracts. In addition, they should help managers efficiently manage the revenue contracts.
Beguru: An Ethno-education of Sasak, Indonesia (Exploring the Principles of Learning Processes & Evaluation)

Each ethnic group has its own local wisdom, which serves as a compass for their life, including in the education sector. Beguru is local wisdom of the Sasak community, Indonesia in education that is rich with principles. This study aims to explore principles of beguru in relation to the learning process and evaluation. The study applied an ethnography-type naturalistic approach. Data was collected by means of ethnographic interviews and observations. Data analysis employed interactive models proposed by Miles, Huberman, Saldana, comprising three stages: data condensation, data display, and conclusion. Based on the method, the study identified 4 principles related to the learning process and 2 principles related to learning evaluation. The four principles of beguru related to the learning process include 1) ethics principle, 2) mastery learning principle, 3) individual learning principle, and 4) learning acceleration principle. While the two principles of beguru related to learning evaluation, include: 1) holistic principle, and 2) concurrent principle. The principles are strongly adhered to during beguru resulting in effective, efficient learning processes and optimum realization of expected competencies. The above principles are very appropriate to apply in contemporary education for improving the quality of learning processes and outcomes.
Heavy viewers, few interactions: YouTubers’ relevance in the lives of Portuguese teenagers

ABSTRACT YouTube is one of the most popular websites amongst the Portuguese youth and their homegrown stars, the YouTubers, are beloved entertainers. This paper presents a qualitative study based on four focus groups with 36 teenagers, aged 12 to 16 years old, and it has three main objectives: to understand their motivations for using it; how this platform (and its contents and authors) interplay with their identity and socialization; and to acknowledge their perspectives on YouTube and YouTubers. It concludes that the sample is made up of very regular viewers, with critical insights on the platform and its contents and creators, but who, despite this overall popularity amidst friends and the easiness of ways to share their interests, regard YouTube and YouTubers as funny entertainers for more individual practices.
DETECTION OF INTER-TURN SHORT-CIRCUIT ON A DOUBLY FED INDUCTION MACHINE WITH D-Q AXIS REPRESENTATION - APPLICATION TO DIFFERENT POWER LEVELS

|This paper presents a method based on the elliptical representation of D-Q currents to detect and quantify an Inter-Turn Short-Circuit (ITSC) fault in windings of a Doubly Fed Induction Machine (DFIM). ITSC is said to be an evolving fault, so it is essential to detect it at an early stage to avoid damage on the machine. Therefore, the method should be able, on the (cid:12)rst hand, to detect the defect and, on the second hand, to quantify its severity. Moreover, this study requires less computation time than classical methods such as harmonic analysis. In this paper, current data are acquired at a sampling frequency of 1 kHz. This method is successful with this low data sampling rate. In order to validate this study, a theoretical analysis with two models of diﬀerent DFIM powers (0.3 kW, 0.25 kW and 11 kW) is carried out (healthy case and faulty case: presence of ITSC), and these results are con(cid:12)rmed by using platforms including Doubly Fed Induction Machines (DFIMs) and Data Acquisition (DAQ) system.
Identification and Validation of Chromobox Family Members as Potential Prognostic Biomarkers and Therapeutic Targets for Human Esophageal Cancer

Background: Chromobox family proteins (CBXs) are vital components of epigenetic regulation complexes and transcriptionally inhibit target genes by modifying the chromatin. Accumulating evidence indicates that CBXs are involved in the initiation and progression of multiple malignancies. However, the expression, function, and clinical relevance such as the prognostic and diagnostic values of different CBXs in esophageal carcinoma (ESCA) are still unclear. Methods: We applied Oncomine, TCGA, GEO, GEPIA, UALCAN, Kaplan–Meier plotter, cBioPortal, Metascape, and TIMER to investigate the roles of CBX family members in ESCA. Additionally, quantitative real-time PCR (RT-PCR), western blot, and immunofluorescence were used to verify the expression of CBX family members in ESCA clinical samples. Results: Compared with normal tissues, the mRNA expression levels of CBX1/3/8 were significantly increased in ESCA, whereas CBX7 mRNA expression was reduced in both the TCGA cohort and GEO cohort. In the TCGA cohort, ROC curves suggested that CBX1/2/3/4/8 had great diagnostic value in ESCA, and the AUCs were above 0.9. Furthermore, upregulation of CBX1/3/8 and downregulation of CBX7 were closely related to the clinicopathological parameters in ESCA patients, such as tumor grades, tumor nodal metastasis status, and TP53 mutation status. The survival analysis indicated that higher CBX1/3/8 mRNA expressions and lower CBX7 expression suggested an unfavorable prognosis in ESCA. High genetic change rate (52%) of CBXs was found in ESCA patients. Functions and pathways of mutations in CBXs and their 50 frequently altered neighbor genes in ESCA patients were investigated; the results showed that DNA repair and DNA replication were correlated to CBX alterations. Moreover, we found a significant correlation between the expression level of CBX family members and the infiltration of immune cells in ESCA. Finally, we verified the expression of CBX family members in clinical samples and found the results were consistent with the databases. Conclusion: Our study implied that CBX1/3/7/8 are potential targets of precision therapy for ESCA patients and new biomarkers for the prognosis.
Longevity and failure mode of posterior ceramic crowns and fixed partial denture

The purpose of this review is to analyse the longevity of posterior all-ceramic crowns and fixed partial dentures; in addition to determine the failure mode. It seeks to assess the risk factors that should be considered with posterior all-ceramic restorations. The review of literature revealed an acceptable longevity for posterior all-ceramic restorations in a 5-year follow up period. This accompanies their aesthetic outcome especially with improving of mechanical properties of glass ceramic by adding reinforcement crystalline phases or using core. The loss of vitality and secondary caries were the common biological complications while ceramic fracture and chipping were the most frequent mechanical complications. Also, the para-functional activity and using implant as an abutment increase the risk of failure especially on posterior teeth.
