Authors: Sun Songsong , Wan Maosong 
Published: February 2021

PurposeBamboo scrimber is a new natural fiber-reinforced composite material in the modern industry. In this paper, the strength characteristics of this material were chosen as the object of study.Design/methodology/approachFirst, axial tensile fracture experiments were conducted on different test specimens to determine the corresponding strength data. Then three commonly used distribution models were applied to analyze the relationship between the strength and survival rate.FindingsThe results show that the tensile data demonstrate obvious dispersion. In addition, the three-parameter Weibull model fits the data best and may be used as the fundamental model for future analysis.Originality/valueSpecial statistical analysis research of the bamboo material experimental results has rarely been discovered. This paper provides a solid foundation for better understanding the mechanism of the bamboo scrimber strength phenomenon.

Purpose
A high-precision gyroscope is an important tool for accurate positioning, and the amplitude stability and frequency tracking ability of the drive control system are important and necessary conditions to ensure the precision of micro-electro-mechanical systems (MEMS) gyroscopes. To improve the precision of MEMS gyroscopes, this paper proposes a method to improve the amplitude stability and frequency tracking ability of a drive control system.

Design/methodology/approach
A frequency tracking loop and an amplitude control loop are proposed to improve the frequency tracking ability and amplitude stability of the drive control system for a MEMS gyroscopes. The frequency tracking loop mainly includes a phase detector, a frequency detector and a loop filter. And, the amplitude control loop mainly includes an amplitude detector, a low-pass filter and an amplitude control module. The simulation studies on the frequency tracking loop, amplitude control loop and drive control system composed of these two loops are implemented. The corresponding digital drive control algorithm is realized by the Verilog hardware description language, which is downloaded to the application-specific integrated circuits (ASIC) platform to verify the performances of the proposed method.

Findings
The simulation experiments in Matlab/Simulink and tests on the ASIC platform verify that the designed drive control system can keep the amplitude stable and track the driving frequency in real time with high precision.

Originality/value
This study shows a way to design and realize a drive control system for MEMS gyroscopes to improve their tracking ability. It is helpful for improving the precision of MEMS gyroscopes.

Authors: Meng Lijun , Li Xinyu , Tan Xin 
Published: February 2021

Purpose
A fiber Bragg grating (FBG) sensor was designed to measure the door gap of automobile bodies.

Design/methodology/approach
The gap sensor was designed through a combination of the sliding wedge and cantilever beam, involving a magnetic force installation and arc structure of the force transmission point. Moreover, the sliding block adopted an anti-magnetic and wear-resistant material and the temperature compensation of the two FBGs was conducted. The magnetic force and contact stress of the sensor were examined to ensure that the sensor exhibited a certain magnetic attraction force and fatigue life. The performance of the gap sensor was examined experimentally.

Findings
The sensor could measure gaps with dimensions of 5 mm to 11 mm, with a sensitivity and measurement accuracy of 150.9 pm/mm and 0.0063% F.S., respectively. Moreover, the sensor exhibited a small gap sensitivity, with a repeatability error of 0.15%, anti-creep properties and magnetic interference abilities.

Originality/value
The sensor is compact and easy to install, as well as use for multiple sensor locations, with a maximum size of 43 mm, a mass of 26 g and installation type of magnetic suction. It can be used for high-precision static and dynamic measurements of the door inner clearance with a resolution of 0.013 mm to improve the efficiency of internal clearance on-line analysis and assembly quality inspection.

AbstractObjectiveTo evaluate the effect of a forced disruption to Medicaid managed care plans and provider networks on health utilization and outcomes for children with persistent asthma.Data SourcesMedicaid managed care administrative claims data from 2013 to 2016, obtained from a southeastern state.Study DesignA difference‐in‐difference analysis compared patients’ outpatient, inpatient, and emergency department (ED) utilization and receipt of recommended services before and after implementation of a statewide redistribution of patients among nine managed care plans.Data Collection/Extraction MethodsEnrollment data for children with asthma were linked to the administrative claims. Children were included if they had a diagnosis of persistent asthma in 2013 and if they were enrolled continuously throughout 2014‐2016.Principal FindingsAmong the 28 537 children with asthma, 26% were forced to switch their managed care plan after the redistribution. Of these, 67% also switched their primary care provider (PCP). Relative to those who remained in their plan, disruption was associated with an additional 2.1 percentage‐point decrease in the number of children who had an outpatient visit per quarter [95%CI −2.8, −1.3], from 71% to 66% (compared to plan stayers: 74% to 71%). Among children experiencing a change to their plan, there was overall a decrease in the proportion of children receiving an asthma‐specific visit per quarter, but there was less of a decrease in children that also changed their PCP [1.6 percentage points, 95%CI 0.7, 2.5], from 9.7% to 8.3% (compared to those who did not switch their PCP: 12% to 8.6%). Indicators of asthma care quality and emergent care utilization were not significantly different between the two periods.ConclusionsWhile there was a decrease in the number of outpatient visits associated with forced disruption of Medicaid managed care plans for children with persistent asthma, there were no consistent associations with worse asthma quality performance or higher emergent health care utilization.

Published: February 2021

AbstractSample collection at the crime scene can introduce variations in DNA recovery based upon the substrate from which a sample is collected, the material of the collection device used, or the storage conditions after collection. There are many factors during this process that can degrade the sample during drying and storage, and before DNA extraction can be performed. The purpose of this study was to evaluate and compare the performance of standard cotton swab collection with the Bode BioSafe® swab, which includes both a desiccant at the swab head and proprietary compounds to prevent degradation of the sample during sample collection and preservation. Blood and touch DNA samples were collected from porous and nonporous substrates and stored at elevated temperatures to simulate accelerated time. DNA quantification and STR profile data were used to assess the performance of the swabs. BioSafe® swab collection resulted in similar DNA yields from blood samples and significantly higher DNA yields from touch samples when compared to collection with cotton swabs. BioSafe® swabs also resulted in higher DNA integrity during long‐term storage, increased STR profile success and improved retention of low‐level contributor alleles.

Published: February 2021

AbstractOne of the hallmarks of aging is an accumulation of cells with defects in oxidative phosphorylation (OXPHOS) due to mutations of mitochondrial DNA (mtDNA). Rapidly dividing tissues maintained by stem cells, such as the colonic epithelium, are particularly susceptible to accumulation of OXPHOS defects over time; however, the effects on the stem cells are unknown. We have crossed a mouse model in which intestinal stem cells are labelled with EGFP (Lgr5‐EGFP‐IRES‐creERT2) with a model of accelerated mtDNA mutagenesis (PolgAmut/mut) to investigate the effect of OXPHOS dysfunction on colonic stem cell proliferation. We show that a reduction in complex I protein levels is associated with an increased rate of stem cell cycle re‐entry. These changes in stem cell homeostasis could have significant implications for age‐associated intestinal pathogenesis.

AbstractAimPostoperative morbidity is high in patients operated on for Crohn's disease (CD) complicated by malnutrition. This study aimed to evaluate the impact of preoperative enteral nutritional support (PENS) on postoperative outcome in patients with CD complicated by malnutrition included in a prospective nationwide cohort.MethodMalnutrition was defined as body mass index <18 kg/m2 and/or albuminaemia <30 g/L and/or weight loss >10%. Failure of PENS was defined as the requirement for additional preoperative parenteral nutrition to PENS. Univariate analysis of the risk factors for PENS failure was performed. Propensity score matching (PSM) was used to compare the outcomes between ‘upfront surgery’ and ‘PENS’ groups. The primary endpoint was the rate of intra‐abdominal septic morbidity and/or temporary defunctioning stoma.ResultsAmong 592 patients included, 149 were selected. In the intention‐to‐treat population including 20 (13.4%) patients with PENS failure after PSM, 78 ‘upfront surgery’ and 71 ‘PENS’‐matched patients were compared, with no significant difference in the primary endpoint. Perforating CD and preoperative intra‐abdominal fistula were associated with PENS failure [37.5 vs 16.1% (P = 0.047) and 41.2% vs 16.2% (P = 0.020), respectively]. After exclusion of these 20 patients, PSM was used to compare 45 ‘upfront surgery’ and 51 ‘PENS’‐matched patients, with a significantly decreased rate of intra‐abdominal septic complications and/or temporary defunctioning stoma in the PENS group (19.6 vs 42.2%, P = 0.016).ConclusionPreoperative enteral nutritional support is associated with a trend but no conclusive evidence of a reduction in intra‐abdominal septic complications and/or requirement for defunctioning stoma. Patients with perforating CD complicated with malnutrition are at risk of PENS failure.
Effects of human‐dominated landscape on the community structure of silphid and dung beetles collected by carrion pitfall traps
Authors: Shizukuda Kyosuke , Saito Masayuki U. 
Published: February 2021

AbstractThe objective of this study was to evaluate the effects of landscape and local environmental factors on the community structure of carrion beetles (silphid and dung beetles) and the abundance of major species in artificial (agricultural and urban landscapes) and forest landscapes in northeastern Japan. Eight study sites were set up in forest landscapes, six in agricultural landscapes, and six in urban landscapes. From June to October 2019, we collected carrion beetles using 385 pitfall traps. A total of 2,119 carrion beetles belonging to 15 species were captured. This included six species of silphid beetles and nine species of dung beetles. The non‐metric multidimensional scaling (NMDS) for carrion beetle community showed that carrion beetles have different community structures in forest landscapes compared to other landscapes. Generalized dissimilarity modeling (GDM) showed that canopy openness and a landscape factor had the large influence on the community structure. The generalized linear mixed model (GLMM) showed that the abundance of the major species was low in open environments. This study indicates that the community structure of carrion beetles differs depending on the landscape in northeastern Japan. The local environment, especially the canopy openness, had a great influence on the community structure and abundance of carrion beetles. Anthropogenic changes at the landscape scale may alter carrion beetle community by significantly changing the local and surrounding environment.

AbstractOn the basis of experimental structural data ten system components were considered in the ZnO‐Nb2O5‐P2O5 thermodynamic model of Shakhmatkin and Vedishcheva – ZnO, Nb2O5, P2O5, ZnP4O11, Zn(PO3)2, Zn2P2O7, Zn3(PO4)2, NbO(PO3)3, (NbO)4(P2O7)3, and NbOPO4. The molar Gibbs energies of ZnO, Nb2O5, P2O5, and Zn3(PO4)2 were taken from the FACT database. The unknown Gibbs energies of the other components were estimated by minimizing the sum of squares of deviations between the calculated and measured equilibrium molar amounts of system components for the series xNb2O5·50ZnO·(50‐x)P2O5. The model was validated by the Multivariate Curve Resolution (MCR) and Malfait's analysis of Raman spectra of xNb2O5·(50‐x)ZnO·50P2O5 glasses. The MCR analysis performed for three components resulted in loadings that were in acceptable coincidence with partial Raman spectra obtained by Malfait's decomposition. Both the MCR and the Malfait's decomposition reproduced the experimental Raman spectra very well ‐ on the level of experimental error.

AbstractAimsTo systematically identify the application of Acceptance and Commitment Therapy among parents of children with chronic health conditions and determine its effectiveness in parental psychological flexibility, psychological distress and parenting behaviour.DesignSystematic review.Data sourcesNine databases (i.e. MEDLINE, PubMed, Embase, Cochrane Library, CINAHL, PsychINFO, Web of Science, China National Knowledge Infrastructure and WanFang Data) were systematically searched from inception to October 2019.Review MethodsQuality of studies was appraised by using the Joanna Briggs Institute critical appraisal checklist. Findings were synthesized narratively. This work was conducted following the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis statement.ResultsEight studies involving 485 parents were included. Results indicated that Acceptance and Commitment Therapy significantly improved parental psychological flexibility and reduced psychological distress compared with usual care and waitlist, but was not significantly different from active treatments. Limited studies have provided very preliminary evidence that Acceptance and Commitment Therapy can significantly improve dysfunctional parenting behaviour than usual care and waitlist. High attrition rate at follow‐up made the overall confidence of maintained effect relatively low.ConclusionThis review provides preliminary evidence that Acceptance and Commitment Therapy is beneficial for improving psychological flexibility, psychological distress and parenting behaviour among parents of children with chronic health conditions. Future studies with rigorous designs and large sample sizes are warranted to verify the evidence and explore its long‐term efficacy.ImpactAcceptance and Commitment Therapy has been increasingly applied to parents of children with chronic health conditions. This review provides positive evidence of its effects on psychological and behavioural outcomes among these parents. This work will help healthcare professionals and researchers with their practice and further research.

Published: February 2021

AbstractAimPatients with gynaecological cancer often experience high levels of uncertainty in illness during chemotherapy and report unmet supportive care needs. Mobile applications (apps) are increasing being used as an easily accessible alternative to support these patients, but a lack of rigorous trials have been conducted to explore their effectiveness. Based on Mishel's uncertainty in illness theory, the Mobile Gynaecological Cancer Support (MGCS) program is an app‐based program that includes four modules: 1) weekly topics, 2) emotional care, 3) discussion centre and 4) health consultation. The aim of this study is to assess the effectiveness of MGCS for Chinese patients with gynaecological cancer receiving chemotherapy in respect of reducing uncertainty in illness and symptom distress and improving quality of life and social support.DesignA multi‐centre randomized controlled trial will be used.MethodsOne hundred and sixty‐eight patients with gynaecological cancer commencing chemotherapy will be recruited from three university affiliated hospitals and assigned to the control or intervention group with block randomization. The control group will only receive routine care. The intervention group will access the MGCS program for 24 weeks and receive routine care. Health outcomes will be evaluated at baseline, 12 weeks, and 24 weeks. Repeated measures multivariate analysis of covariance (intention‐to‐treat) will be used to assess the effectiveness of MGCS.DiscussionThis is the first trial to explore the effectiveness of an app‐based program for patients with gynaecological cancer using a robust and rigorous study design in China. If effective, this trial will provide evidence for an app‐based program to support these patients.ImpactThe knowledge gained can be applied to develop other culturally appropriate app‐based programs for cancer groups worldwide, and provide evidence for health policymakers to allocate more resources and train staff for e‐health.Trial RegistrationChiCTR2000033678 (Chinese Clinical Trial Registry Registered 08 June, 2020).

Published: February 2021

AbstractIntroductionThe evolution of atrioventricular conduction disorders after transcatheter aortic valve implantation (TAVI) remains poorly understood. We sought to identify factors associated with late (occurring ≥7 days after the procedure) high‐grade atrioventricular blocks after TAVI, based on specific pacemaker memory data.Methods and ResultsSTIM‐TAVI (NCT03338582) was a prospective, multicentre, observational study that enrolled all patients (from November 2015 to January 2017) implanted with a specific dual chamber pacemaker after TAVI, with the SafeR algorithm activated, allowing continuous monitoring of atrioventricular conduction. The primary endpoint was the occurrence of centrally adjudicated late high‐grade atrioventricular blocks during the year after TAVI. Among 197 patients, 138 (70.1%) had ≥1 late high‐grade atrioventricular block. Whereas oversizing (p = .005), high‐grade atrioventricular block during TAVI (p < .001), and early (within 6 days) high‐grade atrioventricular block (p < .001) were associated with occurrence of late high‐grade atrioventricular block, self‐expanding prothesis (p = .88), prior right bundle branch block (p = .45), low implantation (p = .06), and new or wider left bundle branch block and lengthening of PR interval (p = .24) were not. In multivariable analysis, only post‐TAVI early high‐grade atrioventricular block remained associated with late high‐grade atrioventricular blocks (Days 0–1: odds ratio [OR], 3.25; 95% confidence interval [CI], 1.57–6.74; p = .001; Days 2–6: OR, 4.13; 95% CI, 2.06–8.31; p < .001), whereas other conventionally used predictors were not.ConclusionOne‐third of pacemaker‐implanted patients do not experience late high‐grade atrioventricular block. Our findings suggest that post‐TAVI early high‐grade atrioventricular block is the main factor associated with occurrence of late high‐grade atrioventricular blocks.

Published: February 2021

AbstractProrocentrum cordatum (Ostenfeld) Dodge—is a planktonic armored dinoflagellate that is a bloom‐forming, potentially toxic cosmopolitan species. The transition from vegetative reproduction to the sexual process has been recently shown for this organism. Here, we present the results of transcriptomic data analysis that uncovered one syngamy‐associated and 16 meiosis‐associated proteins in P. cordatum. We also detected an amino acid sequence homologous to bacterial MutS2 protein. The MutS2 presence and origin in dinoflagellates are discussed for the first time.
