AbstractObjectiveThis study aims to assess the adaptation of the Graded Chronic Pain Scale–Revised to the Turkish language and psychometric properties in patients with primary low back pain.MethodsThe translation from the original text into the Turkish language was carried out step by step in accordance with the recommendations. Structural validity was analyzed by exploratory factor analysis (EFA). Reliability was carried out by internal consistency and test–retest analysis. Convergent validity was evaluated through scales composed in accordance with the research standards for chronic low back pain with the National Institutes of Health Task Force recommendations.ResultsOne hundred thirty‐five patients, 58 (43%) men and 77 (57%) women, completed the study. A two‐factor structure was obtained according to EFA. The first factor consisted of questions 3, 4, and 5, and the same questions constitute the Pain, Enjoyment of Life, and General Activity scale. Cronbach α coefficient r = 0.814 (good internal consistency) was calculated for internal consistency.ConclusionIn this article, we presented the cross‐cultural adaptation process of Graded Chronic Pain Scale–Revised to the Turkish language and evidence of its validity and reliability in a sample of patients with primary low back pain.

AbstractPeriodontal health in the elderly is influenced by numerous factors, including systemic conditions, patient compliance, age‐associated changes, and restorative procedures. The numerous comorbidities seen in the elderly necessitate individualized approaches for treatment planning. In this paper, we review how age, comorbidities, oral hygiene, and restorative dental procedures collectively influence the treatment and management of the periodontium in the elderly. The elderly population is predicted to double in 30 years, which will have an economic impact the dental profession needs to plan for. Preventative and noninvasive treatment, supportive periodontal therapy, and patient‐specific maintenance plans are imperative to maintaining oral health in the older population. Multiple coexisting changes, including xerostomia, altered wound healing, altered bone physiology, altered microbiome, and diminished plaque control, can add complexity to periodontal management. Considerations of the patient's general health, the selected periodontal treatment plan, and the selected completed restorative procedures need to be considered. The influence of caries, fixed prosthodontics, partial dentures, shortened dental arch, and implant therapy can have unintended impacts on periodontal health in the elderly. Adverse periodontal outcomes in the elderly can be minimized by carefully assessing the patient's medical history, impact of medications, functional needs, properly finishing and contouring restorations to avoid plaque accumulation, and designing restorations to allow access for hygiene. Partial dentures can be a source of plaque accumulation leading to periodontal disease, caries, and recession around abutment teeth. A shortened dental arch should be considered as a functional and cost‐effective alternative to partial dentures. With dental implants, the patient's tissue phenotype, keratinized tissue quantity, risk of peri‐implantitis, and patient access for maintaining adequate oral hygiene are all important to consider. Implant risk‐assessment tools show promise by providing a systematic approach for early diagnosis to avoid future complications.
State legislative committee deliberations: Why some issues are difficult and where state legislators turn for help

Published: August 2021

AbstractObjectiveThis study explores why state legislators think some issues are difficult and where they turn for help with these issues.MethodsWe use content analysis of legislators’ interview responses to identify sources of difficulty that arose during committee deliberations.ResultsMany legislators say that issues are difficult because of committee and caucus politics, technical information, interest group pressure, jurisdictional competition, and budget constraints. We find few associations between sources of difficulty and legislator characteristics or institutional context. Mundane issues are often seen as difficult, with culture war issues rarely mentioned.Using cluster analysis, we identify five major categories of issue difficulty. We find that legislators grapple with these categories of difficulty by relying on interest groups, partisan staff, and committee members rather than on caucus leaders, the governor, or their voters.ConclusionThese findings contribute to our understanding of impediments to policy making that legislators navigate in legislative committees.

Authors: Sukri Suzarina Ahmed , Su Hoe Yeak , Ahmad Khairuddin Taufiq Khairi 
Published: August 2021

Polarization tensor (PT) has been widely used in engineering application, particularly in electric and magnetic field areas. In this case, suitable method must be employed in the evaluation of PT in order to make sure that the tensor obtained is higher in its accuracy. Our aim in this paper is to provide simple and easy implemented method to compute first order PT which is based on Gaussian quadrature numerical integration involving linear interpolation. This study provides the comparison between two different orders of Gaussian quadrature, which is order one and order three. The numerical technique of higher order Gaussian quadrature as PT being calculated offer more accurate and higher in its convergence. Relative error for PT is calculated by using provided analytical solution and higher order Gaussian quadrature gives high accuracy and convergence compared to lower order Gaussian quadrature. In this study, the validation of the results obtained by using our proposed method is provided by comparing it with the analytical solution derived from previous researcher. We illustrate the behavior of a tensor of a sphere and ellipsoid with graphical representation.
Data-Driven Forgetting and Discount Factors for Vehicle Speed Forecasting in Ecological Adaptive Cruise Control
Authors: Hyeon Eunjeong , Kim Youngki , Ersal Tulga , Stefanopoulou Anna 
Published: August 2021

Abstract
This paper investigates temporal correlations in human driving behavior using real-world driving to improve speed forecasting accuracy. These correlations can point to a measurement weighting function with two parameters: a forgetting factor for past speed measurements that the vehicle itself drove with, and a discount factor for the speeds of vehicles ahead based on information from vehicle-to-vehicle communication. The developed weighting approach is applied to a vehicle speed predictor using polynomial regression, a prediction method well-known in the literature. The performance of the developed approach is then assessed in both real-world and simulated traffic scenarios for accuracy and robustness. The new weighting method is applied to an ecological adaptive cruise control system, and its influence is analyzed on the prediction accuracy and the performance of the ecological adaptive cruise control in an electric vehicle powertrain model. The results show that the new prediction method improves energy saving from the eco-driving by up to 4.7% compared to a baseline least-square-based polynomial regression. This is a 10% improvement over the constant speed/acceleration model, a conventional speed predictor.
Robust Takagi–Sugeno Fuzzy Fault Tolerant Control for Vehicle Lateral Dynamics Stabilization With Integrated Actuator Fault and Time Delay

Published: August 2021

Abstract
This paper investigates the lateral dynamics stabilization problem for autonomous electric vehicles (AEVs) through the active front steering (AFS) system. A fault-estimation-observer-based robust fuzzy fault tolerant controller is proposed to tackle actuator faults, time delay, modeling nonlinearities, and external disturbances. First, to establish a more accurate dynamics model, the Takagi–Sugeno (T–S) fuzzy modeling strategy is utilized to handle velocity change and parameter uncertainties. Second, to further improve the lateral stability and driving active safety of the AEV, an integrated actuator fault model comprising efficiency loss fault and additional bias fault is proposed. Meanwhile, in order to diagnose actuator additional bias fault, a fuzzy fault estimation observer (FFEO) is designed to acquire fault information online. Third, to eliminate the influence caused by integrated fault and actuator time delay, a fuzzy fault tolerant controller is constructed to improve the handling performance and driving active safety of the AEV. Finally, the effectiveness of the proposed control scheme is demonstrated via a full-car model based on the joint simulation of carsim and matlab/simulink.
Participation in Leisure-Time Aerobic Physical Activity Among Adults, National Health Interview Survey, 1998–2018
Authors: Whitfield Geoffrey P. , Hyde Eric T. , Carlson Susan A. 
Published: August 2021

Background: Adults should perform ≥150 minutes per week of moderate-intensity equivalent physical activity for substantial health benefits and >300 minutes per week for additional benefits. The authors analyzed 21 years of National Health Interview Survey data to better understand trends in aerobic physical activity participation among US adults. Methods: The authors estimated the annual prevalence (1998–2018) of self-reported leisure-time physical inactivity, insufficient activity, meeting only the minimal aerobic guideline, and meeting the high aerobic guideline overall and by selected characteristics. Prevalence differences between 1998 and 2018 were compared across subgroups and periods of significant change were identified using JoinPoint regression. Results: The prevalence of inactivity decreased from 40.5% (1998) to 25.6% (2018) while the prevalence of meeting the high aerobic guideline increased from 26.0% to 37.4%. Increases in meeting the high guideline were similar across age groups, racial/ethnic groups, levels of education, and Census regions. Increases in insufficient activity and meeting the minimal guideline were statistically significant but of relatively small magnitude. Conclusions: The prevalence of inactivity decreased and meeting the high aerobic guideline increased overall and for all subgroups from 1998 to 2018. Physical activity promotion strategies may aim to continue these trends while also narrowing persistent disparities in participation across subgroups.

Authors: Qin Yanan 
Published: August 2021

In this paper, we studied a semidiscrete coupled equation, which is integrable in the sense of admitting Lax representations. Proposed first by Vakhnenko in 2006, local conservation laws and one-fold Darboux transformation were presented with different forms, respectively, in O. O. Vakhnenko, J. Phys. Soc. Jpn. 84, 014003 (2015); O. O. Vakhnenko, J. Math. Phys. 56, 033505 (2015); O. O. Vakhnenko, J. Math. Phys. 56, 033505 (2015). On the basis of these results, we principally construct [Formula: see text]-fold Darboux transformation by means of researching gauge transformation of its Lax pair, and work out its explicit multisolutions. Given a set of seed solutions and appropriate parameters, we can calculate two-soliton solutions and plot their figures when [Formula: see text].

Published: August 2021

Hip’s open reduction combined with Salter innominate osteotomy and femoral osteotomy is the treatment of choice when treating Developmental Dislocation of the Hip (DDH) at walking age. We report a case of a five-year-old girl who underwent a failed surgical procedure of hip’s open reduction, Salter innominate osteotomy, and the femoral osteotomy. One year later, one-stage surgical procedure of hip’s open reduction, Dega pelvic osteotomy, and femoral de-rotation varus shortening osteotomy was performed. During the five-year follow-up, the clinical outcome was evaluated as excellent. The Dega pelvic osteotomy is an effective pelvic osteotomy for DDH, in a case of a failed Salter osteotomy.
Confirming Anomalies

A procedure confirms whether a return-factor correlation is anomalous or results from endogenous simultaneous-equations bias. The identification strategy sorts the cost of capital components for instruments. In the first stage, the initially found factors are regressed on cost instruments. In the second stage, a confirmed anomaly has predicted value significant in returns and exogenous. Taxes, depreciation and capital structure are strong instruments, affecting 1980–2017 quarterly U.S. stock returns. Size, value and profitability decisions are significant in instruments. Returns increase in fitted profits, but not small size. Actual and predicted values have weaker correlation with returns over time.
Almost split morphisms in subcategories of triangulated categories
Authors: Fedele Francesca 
Published: August 2021

For a suitable triangulated category [Formula: see text] with a Serre functor [Formula: see text] and a full precovering subcategory [Formula: see text] closed under summands and extensions, an indecomposable object [Formula: see text] in [Formula: see text] is called Ext-projective if Ext[Formula: see text]. Then there is no Auslander–Reiten triangle in [Formula: see text] with end term [Formula: see text]. In this paper, we show that if, for such an object [Formula: see text], there is a minimal right almost split morphism [Formula: see text] in [Formula: see text], then [Formula: see text] appears in something very similar to an Auslander–Reiten triangle in [Formula: see text]: an essentially unique triangle in [Formula: see text] of the form [Formula: see text] where [Formula: see text] is an indecomposable not in [Formula: see text] and [Formula: see text] is a [Formula: see text]-envelope of [Formula: see text]. Moreover, under some extra assumptions, we show that removing [Formula: see text] from [Formula: see text] and replacing it with [Formula: see text] produces a new subcategory of [Formula: see text] closed under extensions. We prove that this process coincides with the classic mutation of [Formula: see text] with respect to the rigid subcategory of [Formula: see text] generated by all the indecomposable Ext-projectives in [Formula: see text] apart from [Formula: see text].When [Formula: see text] is the cluster category of Dynkin type [Formula: see text] and [Formula: see text] has the above properties, we give a full description of the triangles in [Formula: see text] of the form [Formula: see text] and show under which circumstances replacing [Formula: see text] by [Formula: see text] gives a new extension closed subcategory.

Background. Preeclampsia is a priority obstetric emergency requiring urgent diagnosis and treatment to avert poor pregnancy outcomes. Nonproteinuric preeclampsia poses even greater diagnostic challenges due to contested diagnostic criteria by the clinical practice guidelines and variable clinical presentation. Previously, preeclampsia was only diagnosed if high blood pressure and proteinuria were present. This study determined the prevalence of nonproteinuric preeclampsia and associated factors among women admitted with hypertensive disorders of pregnancy at a referral hospital in southwestern Uganda. Methods. Women with hypertensive disorders of pregnancy were consecutively enrolled in a cross-sectional study at Mbarara Regional Referral Hospital between November 2019 and May 2020. We interviewed all pregnant women ≥20 gestation weeks presenting with hypertension and obtained their sociodemographic, medical, and obstetric characteristics. We excluded women with chronic hypertension. We measured bedside dipstick proteinuria in clean-catch urine. Preeclampsia was defined as hypertension plus any feature of severity including <100,000 platelets/ul, creatinine >1.1 g/dl, and liver transaminases ≥twice upper normal limit with or without proteinuria. We defined nonproteinuric preeclampsia in participants with <+2 urine dipstick cut-off and determined the factors associated with nonproteinuric preeclampsia using logistic regression. Results. We enrolled 134 participants. The mean age was 26.9 (SD ± 7.1) years and 51.5% were primigravid. The prevalence of nonproteinuric preeclampsia was 24.6% (95% CI: 17.9–32.7). Primigravidity (aOR 2.70 95% CI: 1.09–6.72,

p

= 0.032) was the factor independently associated with nonproteinuric preeclampsia. Conclusion. Nonproteinuric preeclampsia was common, especially among primigravidae. We recommend increased surveillance for nonproteinuric preeclampsia, especially among first-time pregnant women, who may not be detected by the traditional criteria. Obstetrics care providers should emphasize laboratory testing beyond proteinuria, among all women with hypertensive disorders of pregnancy to optimally diagnose and manage nonproteinuric preeclampsia.

Published: August 2021

Objective To identify factors associated with recovery time from coronavirus disease 2019 (COVID-19). Methods In this retrospective study, data for patients with COVID-19 were obtained between 21 June and 30 August 2020. An accelerated failure time (AFT) model was used to identify covariates associated with recovery time (days from hospital admission to discharge). AFT models with different distributions (exponential, log-normal, Weibull, generalized gamma, and log-logistic) were generated. Akaike’s information criterion (AIC) was used to identify the most suitable model. Results A total of 730 patients with COVID-19 were included (92.5% recovered and 7.5% censored). Based on its low AIC value, the log-logistic AFT model was the best fit for the data. The covariates affecting length of hospital stay were oxygen saturation, lactate dehydrogenase, neutrophil-lymphocyte ratio, D-dimer, ferritin, creatinine, total leucocyte count, age > 80 years, and coronary artery disease. Conclusions The log-logistic AFT model accurately described the recovery time of patients with COVID-19.

Published: August 2021

On May 17, 2010, Supam Maheshwari and Amitava Saha founded BrainBees Solution with a seed capital of US$39.01 million, which led to the launch of the e-commerce site FirstCry.com. An online e-commerce website that offers all kinds of baby and kids-focused products from diaper pins to strollers. The global and Indian baby care market has seen huge growth in the last few years. It is estimated that by the year 2020, the projected growth of this market will be over 17%. The rising birth rate and disposable income of young parents have also favoured the growth of baby care products. In a country like India, the mortar and brick stores held the major share of the baby care products market. Supam Maheshwari was in the midst of a major decision, but he was faced with some questions. Would he be able to design a unique hybrid model? Would this model help them compete with mortar and brick stores? Would FirstCry be able to build an ecosystem to provide solutions to parents? What strategy should FirstCry adapt for long-term success?
Imposter syndrome in doctors beyond training: a narrative review
Authors: Freeman Joseph , Peisah Carmelle 
Published: August 2021

Objective: To undertake a narrative literature review of imposter syndrome (IS) in doctors beyond training. Method: Twelve studies met inclusion criteria from a systematised search of three databases. Results: There is a paucity of literature on IS, although it has been observed across a diverse range of specialties. IS appears to be more common in female doctors but is also seen amongst male doctors. IS impacts career progression, leadership and mental health. Conclusions: IS causes professional and personal detriment. Solutions must include institutional changes to foster safer workplaces and to address systemic barriers to help-seeking and peer support. Systemic interventions are the only solution to the systemic drivers of IS.
