Published: November 2024

AbstractThis article investigates the adaptive prescribed‐time dynamic surface control (PTDSC) problem for a class of nonlinear strict‐feedback systems with uncertain time‐varying parameters and unknown control gains. First, the spatiotemporal transformation method is employed to eliminate the effect of the unknown control gains in the nonlinear systems. Then, to deal with the problem of “complexity explosion” in the backstepping design framework, a novel dynamic surface control (DSC) strategy is proposed by adding a time‐varying gain to the nonlinear filter. Furthermore, under the Lyapunov stability theory, the rational adaptive laws are cleverly designed to eliminate the influence of the unknown time‐varying parameters. The PTDSC strategy proposed in this paper can guarantee that all the states of the nonlinear systems and the estimate errors of the nonlinear filters converge to zero within the prescribed time. Lastly, a simulation example is provided to demonstrate the effectiveness of the proposed control algorithm.

AbstractObjectivesTo determine the health utility values (HUVs) of overactive bladder (OAB), defined as urinary urgency, usually accompanied by urinary daytime or nocturnal frequency, with or without urinary incontinence, among adults aged ≥65 years and to assess the HUV decrements (disutilities) of OAB according to its severity.MethodsThis cross‐sectional Internet‐based study was conducted between 2 and 9 November 2023, with quota sampling with equal probability for each sex and age group (age 65–74 years and ≥75 years). OAB was defined as an urgency score of ≥2 points and a total score of ≥3 points based on the Overactive Bladder Symptom Score. OAB severity was categorized as mild (total score, ≤5 points) or moderate‐to‐severe (total score, 6–15 points). HUVs were measured using the EuroQol five‐dimension five‐level value set for the Japanese population. Multivariable linear regression models were fitted to estimate the covariate‐adjusted disutilities of OAB. We selected eight covariates (age, sex, body mass index, education, income, smoking, alcohol use, and comorbidities) as potential confounders based on previous studies. The sample size was determined based on previous studies without statistical power calculations.ResultsAmong the 998 participants (51.9% male; mean age, 73.2 years), 158 (15.9%) had OAB, of whom 87 (8.8%) had moderate‐to‐severe OAB. The mean HUVs for participants with mild and moderate‐to‐severe OAB were 0.874 and 0.840, respectively, which were lower compared with the HUV for those without OAB (0.913). After adjusting for relevant covariates, disutilities (95% confidence intervals [CIs] and p values) for mild and moderate‐to‐severe OAB were −0.0334 (−0.0602 to −0.0066, p = 0.014) and −0.0591 (−0.0844 to −0.0339, p < 0.001), respectively.ConclusionsConsistent with previous HUV studies on OAB, our results demonstrated that the prevalence of OAB was associated with substantially lower HUV. The results demonstrate that increased OAB severity is associated with greater disutility.

ABSTRACTBackgroundMacrocephaly is a clinical observation denoted as an occipitofrontal head circumference exceeding two standard deviations above same age and sex norms. By its definition, macrocephaly occurs in approximately 3% of the population. Descriptive epidemiologic evaluations of macrocephaly are lacking in the literature. The primary objective of this study was to describe the prevalence of macrocephaly captured by the Texas Birth Defects Registry (TBDR) by infant sex, rural/urban residence, and select maternal characteristics.MethodsCases of TBDR between 1999 and 2019 with a six‐digit Centers for Disease Control modified‐British Pediatric Association (BPA) code of 742.400 (enlarged brain/head, large head, macrocephaly, megalencephaly) were identified. All pregnancy outcomes and diagnostic certainties were included. Prevalence (per 10,000 live births) and 95% confidence intervals (CIs) were calculated using a Poisson table by rural/urban residence, infant sex, maternal age, education, race/ethnicity, history of diabetes, and body mass index (BMI). Prevalence calculations were repeated across multiple sensitivity analyses including (1) definite, isolated cases excluding those with indication of being either “benign” or “familial”, (2) definite, non‐isolated cases, (3) definite non‐isolated cases excluding chromosomal and syndromic cases, and (4) definite, proportionate (at birth) cases. A secondary objective was to describe the most common co‐occurring congenital defects among definite, non‐isolated cases.ResultsOverall, between 1999 and 2019, 14,637 cases of macrocephaly were identified in the TBDR resulting in a prevalence of 18.12/10,000 live births (95% CI: 17.83–18.42). Most cases were live born (99%), had a definite diagnosis (87%), and were non‐isolated (57%). Prevalence was significantly higher among males, among those with an urban residence, and among mothers who were older, Non‐Hispanic White, who had greater than high school education, who had a history of diabetes, and who were obese. Prevalence patterns remained consistent across all sensitivity analyses. The most common co‐occurring congenital defects among definite, non‐isolated cases were minor and primarily included skull and facial bone anomalies (e.g., plagiocephaly [18%]).ConclusionsTo our knowledge, this is the first epidemiologic evaluation of macrocephaly in a birth defects registry. The long‐term clinical impact of isolated macrocephaly is not well understood and should be the focus of future investigations.
Improving the learning experience in an undergraduate course on microbial metabolism by using an illustrated story
Authors: McKinlay James B. , Kearns Katherine 
Published: November 2024

AbstractIn the classroom, metabolism is often approached and received as a mundane exercise in memorization. Teaching metabolism also faces the challenge of negative perceptions that can impede learning. We sought to improve the learning experience in an undergraduate lecture course on microbial metabolism by implementing an illustrated story that follows an Escherichia coli cell during a cholera outbreak. Feedback from students, compiled over four semesters of relatively minimal intervention, suggests that attitudes improved. Most students also thought that storytelling helped them learn. Exam scores suggested that the story could have had a positive performance impact for some questions that required students to apply correct details to specific situations. Our results suggest that a story could improve the learning experience in a course on a traditionally unpopular topic by both improving emotional responses to the subject matter and by providing a familiar framework upon which to contextualize details.
Circular Economy Adoption in Manufacturing Firms: Evidence From Germany
Authors: Leal Gerusa Giménez , de Castro Vila Rodolfo , Dorado Alexandra Barón , Jäger Angela 
Published: November 2024

ABSTRACTThis paper analyses Circular Economy (CE) practices adopted by manufacturing firms and explores whether the decision to adopt these practices differs in relation to manufacturing sector, company size, or having Environmental Management Systems (EMS) in place. Empirical data from 1191 German manufacturing firms was used to show that the circular practices companies adopt most are framed mainly within Recovery Field of Action (FA), followed by Distribution and Use. Findings highlight differences between sectors and point to a correlation between company size or having an EMS and a higher level of CE adoption, emphasising the need to tailor CE strategies to specific industrial sectors and company size, and highlighting the role EMS plays in facilitating the adoption of CE.

ABSTRACTThe deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive disorder caused by loss of function mutations in the ADA2 gene (previously the CECR1 gene) on chromosome 22q11. The clinical spectrum of the disease is remarkably broad, and its presentations mimic features of polyarteritis nodosa, such as livedoid rash, hematological abnormalities (e.g., cytopenia), early‐onset stroke, hypogammaglobulinemia, and systemic inflammation. Early diagnosis and treatment of DADA2 are crucial, as the clinical features could be potentially life‐threatening but treatable. In this study, a 17‐year‐old male patient is reported with DADA2 whose symptoms mimic those of polyarteritis nodosa. A 17‐year‐old male patient presented with a 14‐year history of abdominal pain, hypertension, and cutaneous lesions initially attributed to polyarteritis nodosa (PAN). He was referred to our center due to ongoing abdominal pain. An abdominal and pelvic computed tomography scan with contrast revealed a retroperitoneal hemorrhage compressing the left kidney. Given his history of abdominal pain, hypertension, hemiparesis, transient ischemic attacks (TIA), anemia, cutaneous lesions, and retroperitoneal hemorrhage, DADA2 was suspected, and a genetic test confirmed the diagnosis. Treatment with anti‐TNF (Adalimumab) was initiated, resulting in noticeable improvement. In the follow up, fever, abdominal pain and TIA episodes were subsided and now he has a good clinical condition. Considering DADA2 and conducting a broad screening for other manifestations is recommended for patients presenting with PAN‐like symptoms. These patients may become symptomatic later in life, and early diagnosis allows for the consideration of disease‐specific treatment options.

Published: November 2024

AbstractEstimating local gas holdup profiles in bubble columns is key for their performance evaluation and optimization, as well as for design and scale‐up tasks. Up to the current day, there are important limitations in the accuracy and range of applicability of the available models in literature. Two alternatives for the prediction of such local fields can be found in the application of empirical models and the development of deep neural networks (DNN). The main drawback preventing the application of these techniques in previous years was the availability of a large enough databank of local gas holdup experimental measurements. Advances over the last decades in measurement techniques have resulted enough data reported in literature to gather a significative databank for these models' development. A databank containing 1252 experimental points was gathered and used for the development of a quadratic model and a DNN with the rectified linear unit (ReLU) algorithm as the activation function and the adaptive moment estimation (ADAM) algorithm as the optimizer function. The quadratic model and the DNN allowed a highly accurate prediction of the local gas holdup profiles, exhibiting a MSE of 0.0013 and 0.0010, respectively, and an and for the quadratic model and the DNN, respectively. Furthermore, these developed models allowed for the estimation of the single and multi‐feature effects of the operation conditions, geometrical characteristics, and physical properties of the fluids, over the local gas holdup profiles. The two developed models exhibited an enhanced predictive quality when compared with other models available in literature.

Published: November 2024

AbstractInspired by the mammalian taste and olfactory systems, array‐based pattern recognition technology has demonstrated significant potential in discerning subtle differences between highly similar compounds and complex mixtures, owing to their unique parallel detection mechanism based on cross‐reactive signals. While optical sensor array has been extensively employed in the field of chemical sensing, they encounter significant challenges in non‐specific recognition of multiple analytes at low concentrations, particularly in rife environments with complex interferences. Poly(p‐phenylene ethynylene)s (PPEs) offer substantial advantages in detecting multi‐analytes at low concentrations, owing to its distinctive optical properties, including the “molecular wire” effect, fluorescence super‐amplification and super‐quenching. This is particularly promising for the parallel detection of ultra‐low concentration multi‐biomarkers in clinical diseases. As the continuous development of PPEs sensor array, more sensitive methods for rapid detection of clinical disease will be further developed. It will promote the further development of the field of early diagnosis of clinical diseases.
Design of Circularly Polarized Koch Snowflake Fractal Antenna With Schottky Band Diode Rectifiers for RF Energy Harvesting Applications
Authors: Sathiyapriya T. , Sudhakar R. 
Published: November 2024

ABSTRACTRadio frequency (RF) energy harvesting has recently become an effective way of powering wireless devices, reducing the requirement of batteries along with their related storage as well as lifespan restrictions. One of the main obstacles to RF energy harvesting is the limited quantity of energy that can be obtained from wireless sources due to weak signal strength, low efficiency, and poor gain. To address these shortcomings, the proposed method is designed based on the circularly polarized Koch snowflake fractal antenna with the Jerusalem cross (JC)–based frequency‐selective surface (FSS) and Schottky diode–based rectifiers for RF energy harvesting applications at the resonance frequency of 5.8 GHz. The electromagnetic energy from the environment can effectively captured using a proposed wide band and high gain antenna designed using a Koch snowflake array based on FSSs. Flame Retardant‐4 (FR‐4) material has good dielectric qualities for electronics, and it is employed as the dielectric substrate in this model; copper serves as the ground plane. The squid game optimizer (SGO) determines the ideal outer snowflake dimensions by maximizing the resonance frequency in order to achieve high gain. The optimally selected outer snowflake length and width are 40 and 23.09 mm. The designed antenna model uses a rectifier based on Schottky diodes for RF energy harvesting applications, which involves converting electromagnetic waves into direct current. The fractal antenna model and RF energy harvesting are designed and simulated using the ANSYS HFSS and Matlab RF toolbox. The model is used to evaluate the antenna's performance by concentrating on gain radiation patterns, S11, and voltage standing wave ratio (VSWR). The Koch snowflake fractal antenna, which uses a JC–based FSS, has been measured for performance at 5.8‐GHz frequency; the values obtained for impedance bandwidth, gain, S11, and VSWR are 7.61%, 9.962 dB, −33 dB, and 1.01, respectively. The analysis of the experimental data demonstrates that the Koch snowflake fractal antenna, which is being proposed for energy harvesting applications, outperforms several other existing designs in terms of effectiveness.

ABSTRACTIntroductionIndeterminate oncocytic/Hürthle cell lesions on thyroid cytology are reflexed to molecular testing. This study aims to examine the cytologic characteristics of thyroid fine‐needle aspiration (FNA) smears with oncocytes classified as atypia of undetermined significance (AUS) with particular molecular patterns that can aid in determining a more conclusive Bethesda category upfront thus decreasing unnecessary testing and associated costs.Materials and MethodsOur pathology database was searched for thyroid FNAs with AUS for oncocyte predominance from 2019 to 2022. Sixty six cases that underwent ThyroSeq testing (33 positive and 33 negative) were selected. Two cytopathologists reviewed the smears for cellularity, colloid: cell ratio, artifacts, lymphocytes, microfollicles, and oncocytic nuclear atypia. Molecular results and surgical follow‐up were obtained through chart review. Statistical analysis was done using STATA16.1 (StataCorp LLC College Station, TX).ResultsAmong the 33 ThyroSeq‐positive cases, 20 had surgical follow‐up. Only 1 case was malignant. Hypercellularity, microfollicular architecture, and oncocytic atypia were associated with a higher incidence of molecular alterations. Five of 66 cases demonstrated microfollicles. Four of these had positive molecular findings, and one was negative. Twenty of 33 (61%) cases with positive molecular findings had no oncocytic nuclear atypia. Of the molecular positive cases with oncocytic atypia that underwent resection, seven of nine (78%) were neoplastic. RAS mutations were the most common finding detected in non‐neoplastic and neoplastic lesions.ConclusionsMicrofollicles were infrequently seen in nodules with oncocytic predominance; however, those that had microfollicles had high incidence of positive molecular findings. Oncocytic nuclear atypia was present in all the resected neoplastic cases. NRAS and KRAS mutations were the most common molecular abnormalities detected.

Authors: Kumar Sandeep , Bhattacharjee Ankur 
Published: November 2024

The rapid growth of the transportation sector in the past few decades has contributed significantly to global warming issues, leading to extensive research on vehicles having nearly zero or total zero tailpipe carbon emissions. The automobiles within this classification belong to hybrid electrical vehicles (HEVs), plug‐in HEVs, battery–electric vehicles (BEVs), fuel‐cell (FC) EVs (FCEVs), and FC HEVs. FCHEVs are powered by a combination of FC systems, rechargeable batteries, ultracapacitors, and/or mechanical flywheels. FC technology appears to hold potential in terms of extended driving distances and quicker refueling times for vehicles that emit no exhaust fumes. A significant number of research studies have examined various types of energy‐storage devices as vehicle power supply, their interfacing with the drive mechanism using power converters and their energy management strategies (EMS). In this article, various EMS for FC‐based EVs are discussed. Classifications of FCEVs, BEVs, and EMSs for FCHEVs are developed by various researchers. In this review report, it is indicated that the existing EMS are capable of performing well, yet further research is required for better reliability and intelligence toward achieving greater fuel efficiency and lifetime of upcoming FCHEVs.

ABSTRACTThe Ordos Basin is among China's largest petroliferous basins, with its southwestern part being a key exploration area. Prior studies indicated that the basin's internal structure was relatively simple, featuring minor developmental faults and primarily stratigraphic–lithologic reservoirs. However, recent research has identified numerous strike‐slip faults in the basin, and their relationship to oil and gas accumulations remains unclear. This study, using integrated interpretations of field outcrops, imaging logging and 3D seismic reflection data, clarifies the characteristics, morphology and formation mechanisms of multi‐period faults in the southwestern Ordos basin. Additionally, the study investigates the relationship between these faults and oil and gas accumulations. Results show that Mesozoic fractures in the southwestern basin are primarily NE‐ and NW‐trending. Seismic profiles reveal that these faults exhibit complex geometries, including upright structures in the Middle to Upper Triassic and floral structures in the Cretaceous. Coherence slices show that Lower Jurassic faults have linear structures NE‐ and NW‐trending, while Cretaceous faults exhibit parallel linear structures ENE‐trending. The study of fault displacement and morphology suggests two evolutionary patterns for Mesozoic faults in the basin: layered development and basement‐activated faulting. The widespread ENE‐ and NW‐trending faults represent a specific mode of tectonic stress transfer in stable cratonic areas with minimal basement fault influence. Conversely, some ENE‐trending faults are significantly influenced by basement activation during various geological periods, penetrating deeply into strata and exhibiting distinct segmentation on a planar scale. This differential fault development results in an uneven distribution of Jurassic oil and gas reservoirs. Significant accumulations of Jurassic oil and gas are found in the ENE‐trending tension–torsional strike‐slip sections, whereas many NW‐trending faults may negatively impact oil and gas reservoirs. This study elucidates the characteristics of Mesozoic faults in the southwestern Ordos Basin, offering valuable guidance for oil and gas exploration and development in the region.
Bank Lending and Policy Interactions—A Comprehensive Assessment for the G20 Countries
Authors: Gramlich Dieter , Yan Meilan , Zhang Dalu 
Published: November 2024

ABSTRACTThis study examines the joint impact from supervisory requirements, monetary policies and rescue packages on the supply of bank loans. Evidence is obtained from conceptual considerations and the empirical investigation of G20 banks over the period 1995–2021. To prepare the analysis of interactions, we first address modelling concepts and consistently identify the effects on bank lending that come from each of the regulatory approaches in isolation. Second, we empirically assess the effects that result from the parallel application of policy actions. Short‐term liquidity ratios in combination with further variables mostly associate with positive interaction effects. In contrast, the joint assessment of long‐term liquidity ratios as well as leverage ratios with other policy actions usually provides negative effects. Overall, the results suggest that unconventional monetary policy and rescue actions can stimulate bank lending only after the institutions have restored their own stability. Interactions of policy actions matter, and both regulatory authorities and bank management should consider them.
