Authors: Xie Linfei , Zhong Shichang , Liang Chenwei 
Published: September 2023

AbstractIn this paper, a compact internally matched architecture of continuous class‐B/J Doherty power amplifier is studied. The influence of symmetric generalized combiner and postmatching network with harmonic control on the bandwidth and efficiency of Doherty power amplifier (DPA) is analyzed in detail. Based on the parameters obtained from theoretical analysis, a design method of internally matched continuous mode DPA (CM‐DPA) is proposed, and a broadband DPA with a size of 22.8 mm  24.5 mm was developed for experimental verification. The test structure shows that the maximum output power at saturation can reach 46.2 dBm. The efficiency of 6 dB back‐off is 58%–63.4%, with good consistency. In the reliability experiment, transistor and matching circuit of the CM‐DPA have a temperature below 100°C at saturation. The output power and efficiency tested at different temperatures (C, C, and C) show that the DPA has high reliability.

AbstractAimsTo compare the effects of bladder training (BT) versus BT with pelvic floor muscle training (PFMT) in women with overactive bladder (OAB) symptoms.MethodsRandomized controlled clinical trial including women with OAB symptoms, randomized into two groups: BT versus BT + PFMT. For 12 consecutive weeks, the women received home BT. The BT + PFMT performed supervised PFMT, once/week, associated at home PFMT protocol. Primary outcomes were urinary urgency, daytime voiding frequency, nocturia and urgency urinary incontinence assisted by both 3‐day bladder diary and International Consultation on Incontinence OAB (ICIQ‐OAB) questionnaire. Secondary outcomes were 24‐h pad test and Patient Global Impression of Improvement. T‐test, analysis of variance, Mann–Whitney (SPSS 20.0) and power/effect size (G‐power) were applied in data analyses.ResultsSixty‐three women were included (B = 31; BT + PFMT = 32). There was no significant statistical difference between groups in terms of urinary symptoms: daytime frequency (BT: pre: 11.59 [±5.80], post: 9.10 [±4.05]; BT + PFMT: pre: 10.67 [±3.73], post: 8.08 [±3.38]) p = 0.75; nocturia: (BT: pre: 1.46 [±0.91], post: 0.82 [±0.82]; BT + PFMT: pre: 1.80 [±2.26], post: 0.82 [±1.15]) p = 0.70; urinary urgency (BT: pre: 3.22 [±4.70], post: 4.49 [±4.32]; BT + PFMT: pre: 6.87 [±5.60], post: 6.15 [±4.52]) p = 0.10; ICIQ‐OAB total score: (BT: pre: 9.16 [±2.55], post: 6.32 [±3.77]; (BT + PFMT: pre: 9.75 [±2.06], post: 5.06 [±3.44] p = 0.30.ConclusionsSupervised PFMT added to BT did not provide further improvements than isolated BT in women with OAB symptoms.
Role of registered dietitians in nasoenteric feeding tube placement
Authors: Yeganehjoo Maryam , Johanek Jennifer 
Published: September 2023

AbstractProvision of enteral nutrition (EN) in hospitalized patients is an integral part of clinical care. For various reasons, including but not limited to delayed enteral access placement and EN initiation, it is becoming more prevalent for registered dietitians (RDs) to place feeding tubes in various clinical settings. Although numerous RDs have expanded their practice by learning this skill, many remain hesitant about adding feeding tube placement to their scope of responsibilities. Feeding tube placement is within RDs' scope of practice. The recently updated Accreditation Council for Education in Nutrition and Dietetics (ACEND) standards is requiring dietetic interns to learn the process and assist in placing feeding tubes. This will help promote the inclusion of this practice and open doors for future advancement in the scope of practice for RDs. This review will provide an overview of feeding tube placement methods, evidence‐based techniques, training, competencies, and barriers to accepting this practice in dietetics.

AbstractAimThis study aimed to compare the apparent diffusion coefficient (ADC) values of the masticatory muscles between patients with and without temporomandibular joint osteoarthritis (TMJ‐OA) on diffusion‐weighted magnetic resonance imaging.MethodsThis prospective study included 120 patients with temporomandibular disorders (TMD), including 60 patients with TMJ‐OA and 60 without TMJ‐OA, and 60 without TMD patients. All patients underwent magnetic resonance imaging of the TMJs at our hospital between November 2011 and January 2017. The regions of interest included the right and left lateral pterygoid muscles, medial pterygoid muscles, and masseter muscles on axial slices. Magnetic resonance images from the TMJ‐OA and control groups were independently evaluated by two oral and maxillofacial radiologists. ADC values were compared between the two groups using Mann–Whitney U tests.ResultsThe respective mean ADC values of the lateral pterygoid muscles in patients with TMJ‐OA and controls were 1.18 × 10−3 and 1.33 × 10−3 mm2/s, respectively. Those for the medial pterygoid muscles were 1.14 × 10−3 and 1.25 × 10−3 mm2/s, while those for the masseter muscles were 1.20 × 10−3 and 1.28 × 10−3 mm2/s, respectively. The mean ADC values of the normal lateral pterygoid, normal medial pterygoid, and normal masseter muscles were 1.29 × 10−3, 1.09 × 10−3, and 1.08 × 10−3 mm2/s, respectively.ConclusionAmong patients with TMDs, the ADC values of the masticatory muscles were significantly higher in patients without TMJ‐OA than in those with TMJ‐OA.

AbstractBackgroundSubmental intubation is an airway management technique wherein an endotracheal tube is guided through incisions in the floor of the mouth and the submental skin after normal orotracheal intubation.Case presentationA 20‐year‐old man with a history of pharyngeal flap construction for a cleft palate was planned for orthognathic surgery. Preoperative nasopharyngoscopy showed that the space lateral to the flap was too narrow for nasotracheal intubation; then submental intubation was performed. No intra‐ or postoperative complications were observed.ConclusionSubmental intubation is a useful alternative to tracheotomy in patients with difficulty in nasotracheal intubation during surgeries requiring occlusal confirmation.
On the identification of material parameters in the relaxed micromorphic continuum
Authors: Sarhil Mohammad , Scheunemann Lisa , Schröder Jörg , Neff Patrizio 
Published: September 2023

AbstractFor modeling materials with size‐effects, the classical Cauchy linear elasticity theory and first‐order homogenization procedures are insufficient. Enriched continua are able to capture such phenomena in principle. In this work, we model the size‐effects of metamaterial beams via the relaxed micromorphic continuum. The material parameters of the relaxed micromorphic model are evaluated. We present a simple procedure for the determination of the material parameters based on the fact that the model operates between two well‐defined scales that are the classical continuum scales of macroscopic linear elasticity, whose stiffness is given by a known macroscopic elasticity tensor, and a microscopic scale with a microscopic elasticity tensor yet to be identified. The size‐effects of metamaterial cantilevers under traction load are captured successfully.
Understanding recent deep‐learning techniques for identifying collective variables of molecular dynamics
Authors: Zhang Wei , Schütte Christof 
Published: September 2023

AbstractHigh‐dimensional metastable molecular dynamics (MD) can often be characterised by a few features of the system, that is, collective variables (CVs). Thanks to the rapid advance in the area of machine learning and deep learning, various deep learning‐based CV identification techniques have been developed in recent years, allowing accurate modelling and efficient simulation of complex molecular systems. In this paper, we look at two different categories of deep learning‐based approaches for finding CVs, either by computing leading eigenfunctions of transfer operator associated to the underlying dynamics, or by learning an autoencoder via minimisation of reconstruction error. We present a concise overview of the mathematics behind these two approaches and conduct a comparative numerical study of these two approaches on illustrative examples.

AbstractAimThe spread of the novel coronavirus infection (coronavirus disease 2019 [COVID‐19]) has caused behavioral changes and mental illness in patients and their attendants during its early phase. The present study aimed to examine the association between precautionary behaviors against COVID‐19 and psychosocial factors in outpatients with pre‐existing disease and their attendants.MethodsWe conducted a cross‐sectional paper‐based questionnaire survey in Chiba University Hospital on 1019 patients and 513 attendants, and a web‐based questionnaire survey in Japan on 3981 individuals from the general population. We evaluated the participants' anxiety about COVID‐19, depression, health anxiety, and precautionary behaviors.ResultsRegarding knowledge and anxiety about COVID‐19, the protective factors for the high precautionary behaviors group were knowledge of COVID‐19 (odds ratio [OR] = 1.178, 95% confidence interval [CI]: 1.099–1.263), anxiety about the spread of COVID‐19 (OR = 1.348, 95% CI: 1.243–1.461), and anxiety about infecting someone with COVID‐19 (OR = 1.135, 95% CI: 1.039–0.239). Regarding psychosocial factors, the protective factors for the high precautionary behaviors group were patients (OR = 1.759, 95% CI: 1.056–2.929), their attendants (OR = 3.892, 95% CI: 1.416–10.700), health anxiety (OR = 2.005, 95% CI: 1.451–2.772), and nondepression states (OR = 1.368, 95% CI: 1.004–1.864).ConclusionOur findings suggest that patients and their attendants may perform high precautionary behaviors. Health anxiety and nondepression states may be associated with high precautionary behaviors.

Published: September 2023

AbstractObjectiveDespite increased attention to the utility of collaborative care models for promoting whole‐person care in cancer populations, there is a paucity of empirical research testing the impact of these care models on effectively identifying and serving highly distressed cancer patients. This study sought to experimentally test the effectiveness of a year‐long collaborative care program on referral rates to psycho‐oncology services for patients with moderate to high distress.MethodsData for this study consisted of 11,467 adult patients with cancer who were screened for psychosocial distress 6‐months prior to, and following, the integrated collaborative care intervention. Psychosocial referral rates pre‐, peri‐ and post‐ intervention were analyzed.ResultsFindings indicated high distress patients were at 3.76 (95% CI [2.40, 5.87]), 5.03 (95% CI [3.25, 7.76]), and 7.62 (95% CI [5.34, 10.87]) times increased odds of being referred during the pre‐intervention, peri‐intervention, and post‐intervention, respectively, when compared to low distress patients, and these differences across time were significantly different (p = 0.04).ConclusionFindings from this study suggest that the successful initiation of a collaborative care model within a comprehensive cancer center contributed to significantly greater referral rates of cancer patients with moderate to high distress to psycho‐oncology services. This study contributes to the growing consensus that collaborative care models can positively impact the care of complex medical patients.

AbstractColitis‐associated bowel cancer (CAC) is one of the most common malignancies associated with inflammation. The aim of this study was to observe a new herbal formula “Xiaotan Sanjie Fang” (XTSJF) derived from the addition and subtraction theory of traditional medicine as an alternative to CAC treatment by “Daotan Decoction” and “Xiaojianzhong Decoction”, which are famous traditional Chinese medicine prescriptions for the treatment of inflammatory diseases of the digestive tract. We constructed a DMH/DSS inflammation‐associated colorectal cancer rat model and treated CAC rats with sulfasalazine and different doses of XTSJF. The results showed that the body weight of rats treated with different doses of XTSJF increased, which was still lower than that of normal rats; AFC decreased significantly compared with the model group and the positive control group, and the final dose was superior to the low dose; histological observation revealed that it could maintain the normal structure of colon tissue, while it could inhibit the secretion of VEGF, COX2, and AQP1 and the expression of pro‐inflammatory cytokines IL‐6, IL‐1β, and TNF‐α, promote the expression of caspase‐3 and BAX and inhibit the expression of Bcl‐2. Taken together, these data suggest that XTSJF can inhibit COX‐2/VEGF expression to prevent the development of inflammation‐associated colorectal cancer.
Internal migration following adverse life events: Assessing the likelihood of return migration and migration toward family
Authors: Spring Amy , Gillespie Brian Joseph , Mulder Clara H. 
Published: September 2023

AbstractThere are well‐documented associations between life course changes and migration; yet, the occurrence, order, and timing of reasons for migrating are growing increasingly diverse. Migration following adverse life events, such as a divorce or an involuntary job loss, may be qualitatively distinct from migration undertaken for other reasons. Moves, especially long‐distance moves, following adverse life events, may be defined more by seeking family and familiar locations. Moreover, a heightened probability of migration may occur not only immediately after an adverse life event but also in the years after. We explore these questions in the US context with longitudinal data from the 1983 to 2019 waves of the Panel Study of Income Dynamics, which provides information on residential locations, locations of family members, and adverse life events for individuals over time. We focus on five specific events: divorce, the death of a spouse, involuntary job loss, the onset of a chronic physical health condition, and the onset of a chronic mental health condition. Using multivariate regression, we find that divorce and job loss induce long‐distance moves, especially return moves and moves towards family. Chronic physical conditions deter moving in general but increase the chances of return moves (after a period of time) and moves towards family. These results have implications for understanding migration as a response to adverse life events, both immediately and over time.
Potential impact of all‐sky assimilation of visible and infrared satellite observations compared with radar reflectivity for convective‐scale numerical weather prediction
Authors: Kugler Lukas , Anderson Jeffrey L. , Weissmann Martin 
Published: September 2023

AbstractAlthough cloud‐affected satellite observations are heavily used for nowcasting applications, their use in regional data assimilation is very limited despite possible benefits for convective‐scale forecasts. In this article, we estimate the potential impact of assimilating cloud‐affected satellite observations of visible (0.6 m) and near thermal infrared wavelengths (6.2 and 7.3 m) relative to the impact of assimilating radar reflectivity observations. We employed observing‐system simulation experiments with a perfect‐model forecast for two cases of strong convective summertime precipitation. Observations are simulated using the radiative transfer model RTTOV/MFASIS and assimilated by the ensemble adjustment Kalman filter in the Data Assimilation Research Testbed. The Weather Research and Forecasting model at 2‐km grid resolution was used for forecasts. Results show that satellite observations can be nearly as beneficial as three‐dimensional radar reflectivity observations. Under favorable conditions, where the prior contains no error in the stage of storm development but only in horizontal position and strength, the assimilation of visible observations leads to 88% of the radar impact. Under more difficult conditions, the impact of visible and infrared observations still reached 50 and 79%, respectively.
An analytic journey in an industrial classification problem: How to use models to sharpen your questions
Authors: Kenett Ron S. , Gotwalt Chris , Poggi Jean‐Michel 
Published: September 2023

AbstractThe mathematician and bio‐scientist Sam Karlin is quoted stating that “The purpose of models is not to fit the data but to sharpen the question”. In this paper, we describe a journey between questions, models and data analysis to reach specific goals. This journey is typical in industrial, engineering, biology and social science applications. It contrasts regulated clinical research where a statistical analysis plan is declared before data collection. We consider random forests, ridge regression, lasso and elastic nets. To make our point, we use a case study of 63 sensors collected in the testing of an electronic system. The paper lists a sequence of questions and how they were tackled by statistical analysis to meet the analysis goal. Eventually, we were able to provide a robust parsimonious and effective model for predicting the system condition using a subset of the 63 sensors. In handling this problem, we develop and apply several innovative methods and insights that can prove useful in other contexts.
Radiation recall pneumonitis from immune checkpoint inhibitors after extra pulmonary radiation
Authors: Kao Leslie E. , Stover Diane 
Published: September 2023

AbstractRadiation recall is an unpredictable, poorly understood inflammatory reaction within the confines of previously irradiated tissue that occurs following exposure to a systemic agent. In this article, we will focus on a subcategory of radiation recall, called radiation recall pneumonitis (RRP), precipitated by immune checkpoint inhibitors (ICI). Historically, RRP can develop weeks to years after radiation treatment to the lung, most commonly after receiving certain chemotherapeutic agents, but more recently has been recognized in association with immunotherapy agents (ICIs). Up until now, RRP following exposure to ICIs has been described in patients who have received radiation to the lung itself. Here we present three cases of RRP in patients who received radiation to areas adjacent to the lung parenchyma, and developed pulmonary infiltrates in an area adjacent to the radiation field while on ICI therapy. Since ICI induced RRP is treatable and steroid sensitive, early recognition and treatment are important.

Published: September 2023

SummaryDespite the rapid growth and popularization of virtual reality (VR) applications, which have enabled new concepts for handling and solving existing problems through VR in various domains, practices related to software engineering have not kept up with this growth. Recent studies indicate that one of the topics that is still little explored in this area is software testing, as VR applications can be built for practically any type of purpose, making it difficult to generalize knowledge to be applied. In this paper, we present an approach that combines metamorphic testing, agent‐based testing and machine learning to test VR applications, focusing on finding collision and camera‐related faults. Our approach proposes the use of metamorphic relations to detect faults in collision and camera components in VR applications, as well as the use of intelligent agents for the automatic generation of test data. To evaluate the proposed approach, we conducted an experimental study on four VR applications, and the results showed an
of the solution ranging from 93% to 69%, depending on the complexity of the application tested. We also discussed the feasibility of extending the approach to identify other types of faults in VR applications. In conclusion, we discussed important trends and opportunities that can benefit both academics and practitioners.

Published: September 2023

SummaryAtmospheric flow is the main factor affecting the wind load of urban buildings. The measured data observed continuously from the 325‐m‐tall Beijing Meteorological Tower (BMT) during 2013–2017 is employed to investigate the vertically‐layered structure and surface roughness parameters of the urban boundary layer. Based on the local similarity theory and analysis results of the atmospheric stability and local friction velocity, it can be determined that the height of 80 m is near the bottom of the inertial sub‐layer, the range below this height belongs to the roughness sub‐layer, 140 m belongs to the inertial sub‐layer, and 200 m and 280 m are in the mixing layer. The local friction velocity at 80 m can be considered a relatively reliable value as the friction velocity. Moreover, seasonal effect on local friction velocity is minimal. According to the fitting result of near‐neutral strong wind samples by the log‐law, it is concluded that to obtain a more accurate wind speed profile, all layers should be included when picking fitting heights. In addition, surface roughness parameters are affected by the wind direction and speed. The variation according to the wind direction corresponds to the topographical distribution surrounding the BMT, and the higher range of wind speed may be more applicable for estimating surface roughness parameters.
