Authors: Zhang Min , Sun Zhiming , Yang Yuehua , Zhou Jian , Ba Lei 
Published: April 2023

AbstractAimComplete perforation of the bladder caused by an intrauterine device (IUD) is rare. This study examined the characteristics of patients associated with IUD‐related bladder perforation and evaluated the relationship between mislocated IUDs and their potential complications.MethodsFrom October 2005 to December 2021, 13 reports regarding complete perforations to the bladder by IUDs were retrieved from the National Contraceptives Adverse Reaction Monitoring System of China. The clinical features of these cases were analyzed.ResultsThe median patient age was 30 (range, 27–46) years. There were four cases (4/13, 30.8%) with IUDs placed during lactation, one case (1/13, 7.7%) with an IUD placed after medical abortion, and eight cases (8/13, 61.5%) placed after menstruation. Seven cases (7/13, 53.9%) were first‐time IUD users. The median duration of IUD placement was 47 (range, 1–145) months. Unexpected pregnancy was reported in five cases (5/13, 38.5%). Six cases (6/13, 46.2%) reported bladder stones with varying degrees of abdominal pain or urinary tract infection. Removal methods included laparotomy (four cases), cystoscopy (four cases), laparoscopy (two cases), laparoscopy combined with cystoscopy (two cases), and laparotomy after cystoscopy (one case). All IUDs were successfully removed.ConclusionsComplete perforation to the bladder by IUDs is a rare adverse event. Regular follow‐up is required after the placement of IUDs. The possibility of uterine perforation should be investigated if IUD users encounter persistent lower abdominal pain or urinary tract infection.
Undereducation is afoot: Assessing the lack of acral lentiginous melanoma educational materials for skin of color
Authors: Elad Vissy M. , Anton Trevena , Ganios Natalie C. , Rebecca Vito W. 
Published: April 2023

AbstractAcral lentiginous melanoma (ALM) is a subtype of cutaneous melanoma notorious for poor outcomes that disproportionately affect individuals with skin of color (e.g., African‐, Hispanic‐, Asian‐descent) when compared to mortality rates among non‐Hispanic White populations. There are several societal factors that contribute to racial disparities in ALM, including a lack of representative educational material in the context of patient education and medical instruction. This gap in representative information for the US population includes risk of disease, patterns of incidence, and differences in disease presentation in skin of color. The atypical presentation of ALM on acral volar skin sites makes early detection challenging and necessitates an increased index of suspicion on the part of physicians and patients alike. Studies underscoring the importance of early detection in reducing mortality risk make the availability of adequate representative educational materials indispensable.
Intellectual property‐related preferential trade agreements and US offshoring to developing countries
Authors: Canals Claudia , Klein Michael A. , Şener Fuat 
Published: April 2023

AbstractInternational standards in the protection of intellectual property rights (IPRs) are increasingly guided by bilateral and regional preferential trade agreements (PTAs). We estimate the effect of these IP‐related PTAs on US offshoring in developing countries. We utilize a difference‐in‐difference empirical methodology that addresses several sources of endogeneity and exploits industry variation in the importance of IPRs. IP‐related PTAs are associated with a substantial increase in US offshoring in IP‐intensive industries relative to non‐IP‐intensive industries. This increase is concentrated within the boundaries of the multinational firm. PTA‐induced IPRs reform impacts both the intensity and composition of multinational activity in developing countries.
Vibration data‐driven machine learning architecture for structural health monitoring of steel frame structures
Authors: Naresh M. , Sikdar S. , Pal J. 
Published: April 2023

AbstractA vibration data‐based machine learning architecture is designed for structural health monitoring (SHM) of a steel plane frame structure. This architecture uses a Bag‐of‐Features algorithm that extracts the speeded‐up robust features (SURF) from the time‐frequency scalogram images of the registered vibration data. The discriminative image features are then quantised to a visual vocabulary using K‐means clustering. Finally, a support vector machine (SVM) is trained to distinguish the undamaged and multiple damage cases of the frame structure based on the discriminative features. The potential of the machine learning architecture is tested for an unseen dataset that was not used in training as well as with some datasets from entirely new damages close to existing (i.e., trained) damage classes. The results are then compared with those obtained using three other combinations of features and learning algorithms—(i) histogram of oriented gradients (HOG) feature with SVM, (ii) SURF feature with k‐nearest neighbours (KNN) and (iii) HOG feature with KNN. In order to examine the robustness of the approach, the study is further extended by considering environmental variabilities along with the localisation and quantification of damage. The experimental results show that the machine learning architecture can effectively classify the undamaged and different joint damage classes with high testing accuracy that indicates its SHM potential for such frame structures.
Traj2Traj: A road network constrained spatiotemporal interpolation model for traffic trajectory restoration

Published: April 2023

AbstractIn transportation, the trajectory data generated by various mobile vehicles equipped with GPS modules are essential for traffic information mining. However, collecting trajectory data is susceptible to various factors, resulting in the lack and even error of the data. Missing trajectory data could not correctly reflect the actual situation and also affect the subsequent research work related to the trajectory. Although increasing efforts are paid to restore missing trajectory data, it still faces many challenges: (1) the difficulty of data restoration because traffic trajectories are unstructured spatiotemporal data and show complex patterns; and (2) the difficulty of improving trajectory restoration efficiency because traditional trajectory interpolation is computationally arduous. To address these issues, a novel road network constrained spatiotemporal interpolation model, namely Traj2Traj, is proposed in this work to restore the missing traffic trajectory data. The model is constructed with a seq2seq network and integrates a potential factor module to extend environmental factors. Significantly, the model uses a spatiotemporal attention mechanism with the road network constraint to mine the latent information in time and space dimensions from massive trajectory data. The Traj2Traj model completes the road‐level restoration according to the entire trajectory information. We present the first attempt to omit the map‐matching task when the trajectory is restored to solve the time‐consuming problem of map matching. Extensive experiments conducted on the provincial vehicle GPS data sets from April 2018 to June 2018 provided by the Fujian Provincial Department of Transportation show that the Traj2Traj model outperforms the state‐of‐the‐art models.

Published: April 2023

AbstractBackgroundOral and parenteral drug delivery in horses can be difficult. Equine‐specific transdermal drug formulations offer improved ease of treatment; development of such formulations requires a deeper understanding of the structural and chemical tissue barrier of horse skin.Hypothesis/ObjectivesTo compare the structural composition and barrier properties of equine skin.AnimalsSix warmblood horses (two males, four females) with no skin diseases.Materials and MethodsRoutine histological and microscopic analyses were carried out with image analysis for skin from six different anatomical locations. In vitro drug permeation was analysed using a standard Franz diffusion cell protocol coupled with reversed phase‐high‐performance liquid chromatography detailing flux, lag times and tissue partitioning ratios of two model drug compounds.ResultsEpidermal and dermal thicknesses varied between sites. The dermal and epidermal thicknesses of the croup were 1764 ± 115 μm and 36 ± 3.6 μm, respectively, and were significantly different (p < 0.05) from the inner thigh thicknesses which were 824 ± 35 μm and 49 ± 3.6 μm. Follicular density and size also varied. The highest flux for the model hydrophilic molecule (caffeine) was for the flank (3.22 ± 0.36 μg/cm2/h), while that for the lipophilic molecule (ibuprofen) was for the inner thigh (0.12 ± 0.02 μg/cm2/h).Conclusions and Clinical RelevanceAnatomical location differences in equine skin structure and small molecule permeability were demonstrated. These results can aid in the development of transdermal therapies for horses.

Published: April 2023

The purpose of this study was to assess the efficacy of a combined training program (CTP) in reducing the effects of dual tasking on the temporal parameters and kinematics of gait, as compared with single-task gait. A controlled, randomized, intervention study was performed in an intervention group and a control group. The intervention group attended three weekly CTP sessions for 24 weeks. Gait pattern was evaluated prior to the baseline intervention, at 12 weeks, and at 24 weeks (Repost). The sample was composed of 22 subjects diagnosed with multiple sclerosis with an Expanded Disability Status Scale score of 0–5.5. A total of 12 patients were allocated to the intervention group and another 10 to the control group. A three-dimensional photogrammetry scanner was connected to a selective attention system designed to present a dual-task gait condition. Dual tasking had an impact on all spatiotemporal parameters of gait, and the most remarkable effect of dual tasking was on double-support time, which increased by 9% with respect to normal walking. In contrast, dual tasking had a trivial effect on single-support time. The CTP was effective in reducing the effects of dual tasking on stride length and velocity of the center of mass after Repost of training (p < .05). The CTP reduced time in double-support phase, whereas single-support time increased after Repost of intervention. The application of the CTP had no effect on the cost of the double task after 12 weeks of intervention. It is suggested to increase the application time over Repost.

Published: April 2023

Via a school-based survey, we used a developmental assets framework to investigate associations of internal and social characteristics and weight-based bullying with sport and physical activity (PA) among female adolescents with high weight status (n = 4,468; Mage = 14.9 years, SDage = 1.3; body mass index ≥ 95th percentile). Participants reported ≥60 min of PA on approximately 3.0 days (SD = 2.1) in the previous week. Over one-third played organized team sports, averaging 3.5 days (SD = 1.5) per week. Weight-based bullying was common (46%) and unassociated with lower sport and PA. Results from t-tests and chi-squared tests demonstrated that adolescents who played sport (vs. those who did not) had higher internal developmental assets, better perceived health, and stronger perceptions of caring from parents, friends, and other community adults. Similarly, adolescents engaging in more PA reported higher developmental assets. In regression models adjusted for all variables and demographic characteristics, higher internal developmental assets, better perceived health, and stronger perceptions of caring from adults in the community were positively and significantly associated with increased odds of sport participation and higher PA. Findings suggest female adolescents with high weight status have internal and social assets related to their participation in PA and sport, despite experiencing weight-based bullying. Adults (e.g., coaches, parents, and healthcare professionals) should help female adolescents with high weight status participate in sport and PA and build developmental assets. Adults should also recognize the frequent weight-based bullying youth encounter and strive to mitigate it in sport and PA contexts.
Oklahoma’s coordinated response to more than a decade of elevated seismicity
Authors: Murray* Kyle E. , Brooks Colin , Walter Jacob I. , Ogwari Paul O. 
Published: April 2023

ABSTRACT
In the period between 1961 and 2008, Oklahoma, USA, averaged about two M ≥3.0 earthquakes per year, with no damage to any built infrastructure. A substantial increase in seismic activity was first observed in 2009, when there were 20 M ≥3.0 earthquakes, and activity peaked in 2015, when over 900 M ≥3.0 earthquakes occurred. Because of the unprecedented increase in seismic activity, the governor’s office of Oklahoma formed a Coordinating Council of researchers, regulators, industry, and other stakeholders in 2015. The Coordinating Council was led by the Secretary of Energy and Environment and charged with understanding and attempting to mitigate (that is, reduce, if not eliminate) induced seismicity and potential impacts. Major outcomes of the coordinated efforts included delineation of an area of interest (AOI) for seismicity in Oklahoma, modifications to underground injection control (UIC) well completion depths and injection rates into UIC wells in the AOI, development of the Oklahoma Well and Seismic Monitoring (OWSM) application used for regulatory oversight and action, modified well completion protocols, a more robust seismic network, and numerous scientific investigations and publications.
Because of concerted efforts between regulators and industry, disposal into the Arbuckle Group, the primary zone for wastewater disposal, in the AOI was reduced by more than 50% though oil production continued to increase. Seismic activity decreased over a 6 yr period with 619, 302, 195, 65, 39, and 29 M ≥3.0 earthquakes occurring in 2016, 2017, 2018, 2019, 2020, and 2021, respectively. At the time of latest updates to this chapter (16 October 2022), there have been 12 M ≥3.0 earthquakes and one M ≥4.0 earthquake, so the projected total of M ≥3.0 earthquakes in 2022 is 17. Using these metrics, the coordinated efforts of Oklahoma stakeholders appear to have successfully reduced seismicity with respect to frequency and number in the range of minor but often felt (M 3.0–3.9), light (M 4.0–4.9), and moderate (M 5.0–5.9) earthquakes. So, the Oklahoma case provides examples of how stakeholder action diminished seismic hazards and how similar actions could be used to reduce induced seismicity in other areas where injections occur.

Published: April 2023

Abstract
A study is performed of the effect the way of standardizing the molecular structure and parameters of calculating molecular fingerprints has on the accuracy of predicting constants of acidity. It is shown that standardization (i.e., the choice of the tautomeric form and the way of writing the structure of the molecule) using OpenEye QuacPac gives the best results, but the RDKit library allows comparable accuracy to be achieved. It is established that how the charge state is chosen has a great effect on the accuracy of predictions. The accuracy of predictions depending on the radius (size of substructures) of circular molecular fingerprints is studied, and the best results are achieved using radius r = 2. A random forest, a machine learning algorithm, is used. It is also shown that the use of support vectors ensures fairly high accuracy when optimizing hyperparameters.

Published: April 2023

ObjectivesTo examine the prevalence of socioemotional and behavioural difficulties (SEBDs) in children with chronic physical conditions (CPCs) and to analyse how this prevalence varied with the type and number of CPCs and the age of the child.DesignCross-sectional study of a secondary data analysis of the Longitudinal Study of Australian Children.SettingAn Australian nationally representative sample of general population of children.Participants15 610 children-waves aged 6–14 years.Intervention/exposureChildren reported to have at least 1 of the 21 CPCs by their parents.Main outcome measuresClinically relevant SEBDs were defined using standardised cut-offs of the parent-administered Strengths and Difficulties Questionnaire.ResultsChildren with a CPC have significantly increased odds of total, internalising and externalising SEBDs than those without (total SEBDs, adjusted odds rartio or OR 3.13, 95% CI 2.52 to 3.89), controlling for sex, age, socioeconomic status and parental mental health status. The highest prevalence of total SEBDs was found in children with chronic fatigue (43.8%), epilepsy (33.8%) and day wetting (31.6%). An increasing number of comorbid CPCs was associated with a rising prevalence of SEBDs. On average, 24.2% of children with at least four CPCs had SEBDs. These children had 8.83-fold increased odds (95% CI 6.9 to 11.31) of total SEBDs compared with children without a CPC. Age was positively related to the odds of SEBDs.ConclusionChildren with a CPC have a significantly increased risk of having SEBDs than those without. These findings highlight the need for routine assessment and integrated intervention for SEBDs among children with CPCs.
Long-term association between neighbourhood socioeconomic deprivation in early childhood and perceived stress in early adulthood: a multilevel cohort study
Authors: Jakobsen Andreas Lindegaard 
Published: April 2023

BackgroundPrevious studies have shown that neighbourhood socioeconomic deprivation is related to mental health problems, with chronic stress responses as one possible biopsychological pathway; however, less is known about the possible long-term effects of neighbourhood deprivation throughout the life course. The aim of this study was to examine the association between neighbourhood socioeconomic deprivation in early childhood and perceived stress in early adulthood.MethodsData from the, Danish National Health Survey 2017 in which Cohen’s 10-item Perceived Stress Scale was measured (range 0–40) were used to follow a cohort consisting of all survey respondents aged 20–24 years born between 1992 and 1996. The respondents were linked to Danish register data, including data on the parent(s) with whom the respondents lived, to measure family-level socioeconomic characteristics, parental mental health problems and neighbourhood socioeconomic deprivation at age 3 for each respondent. Furthermore, the respondents were linked to georeferenced neighbourhoods. Linear mixed models were used to estimate the association between neighbourhood socioeconomic deprivation at age 3 and perceived stress at age 20–24.ResultsA 1 SD increase in neighbourhood socioeconomic deprivation in early childhood was associated with a 0.59-point increase in perceived stress in early adulthood (95% CI 0.41 to 0.77). The association was attenuated but remained statistically significant after controlling for individual and family characteristics and neighbourhood socioeconomic deprivation in early adulthood (coef 0.26, 95% CI 0.06 to 0.46).ConclusionThe findings suggest that children growing up in more socioeconomically deprived neighbourhoods may be prone to higher levels of perceived stress later in life.

AbstractIn this work, we scrutinize the consistency of spacetime homogeneous Gödel-type metrics within f(R, Q, P) theories of gravity for well-motivated matter sources. As it is well known, such geometries allow for causality violation. We provide general conditions to engender completely causal solutions in a manner completely different from general relativity. We take some specific models, for instance, $$f(R,Q,P)=R -\dfrac{\mu ^{4n+2}}{\left( a R^2+b Q+c P\right) ^n}$$

Influence of Inter-Molar Concentration of Cu and Zn on the Various Properties of Sprayed Nanocrystalline Cu2ZnSnS4 Thin Films
Authors: Chandel Tarun , Sharma Ranjana , Kumar Ashwani , Prasher Dixit 
Published: April 2023

In this work, the quaternary nanostructured Cu2ZnSnS4 (CZTS) thin films were deposited on ITO glass substrates at a temperature of 300[Formula: see text]C by spray pyrolysis method and the influence of inter-molar concentration variations of copper and zinc on the structural, morphological and optical properties of grown samples was studied. The films were characterized by different sophisticated techniques including X-ray diffractometer (XRD), scanning electron microscopy (SEM), Raman spectroscopy and UV–Vis spectroscopy. The solitary presence of kesterite tetragonal phase with favored orientation along (112) plane is confirmed by XRD patterns and Raman spectroscopy. However, due to the variation in lattice parameters, a moderate shifting in (hkl) planes was observed. SEM micrographs and EDAX analysis showed the uniform morphology of the so-grown CZTS films covered with nanoplates of different sizes and the ionic compositional variation of the precursor solution matches with the elemental variation in the grown samples. A minor nonstoichiometry in chemical composition ratio [Formula: see text] from 0.74 to 1.24 was noticed in the films. Optical studies of CZTS films showed that these films possess optical band gap ranging from 1.45[Formula: see text]eV to 1.60[Formula: see text]eV.
