AbstractElectric‐field‐induced phase transitions in Bi0.5Na0.5TiO3‐based relaxor ferroelectrics are essential to the control of their electrical properties and consequently in revolutionizing their dielectric and piezoelectric applications. However, fundamental understanding of these transitions is a long‐standing challenge due to their complex crystal structures. Given the structural inhomogeneity at the nanoscale or sub‐nanoscale in these materials, dielectric response characterization based on terahertz (THz) electromagnetic‐probe beam fields is intrinsically coordinated to lattice dynamics during DC‐biased poling cycles. The complex permittivity reveals the field‐induced phase transitions to be irreversible. This profoundly counters the claim of reversibility, the conventional support for which is based upon the peak that is manifest in each of four quadrants of the current–field curves. The mechanism of this irreversibility is solely attributed to polar clusters in the transformed lattices. These represent an extrinsic factor, which is quiescent in the THz spectral domain.
Storage performance of primed bell pepper seeds with 24‐Epibrassinolide
Authors: Barboza da Silva Clíssia , Marcos‐Filho Julio 
Published: February 2020

AbstractSeed response to priming with 24‐epibrassinolide (24‐EpiBL) has been studied to investigate the effects on speed of germination, often leading to improved stand establishment. However, knowledge about the response of primed seeds treated with 24‐EpiBL during storage remains insufficient. This research was performed to verify the effects of bell pepper seed priming (Capsicum annuum L.) with 24‐EpiBL after storage. Two cultivars (AF‐6 and AF‐7) were used, represented respectively by three and four seed lots of different physiological potential. All lots were stored for 0, 3, 6, 9, and 12 mo after priming with 24‐EpiBL. Seeds were evaluated for germination and vigor (germination first count; saturated salt accelerated aging, and using the Seed Vigor Imaging System); unprimed seeds represented the control. Priming with 24‐EpiBL promoted positive effects on germination speed, seed tolerance to heat stress, and initial development of seedlings with responses being more evident in lower vigor seed lots. The beneficial effects of priming with 24‐EpiBL in bell pepper seeds is maintained after storage, but may gradually decrease after longer storage period.
Salivary secretory immunoglobulin A variation between female varsity athletes and nonathletes
Authors: Chaney Carlye , Quinn Elizabeth A. 
Published: February 2020

AbstractObjectivesExercise can lead to changes in immune function. To further investigate this relationship, we examined possible differences in salivary secretory immunoglobulin A (sIgA) secretion rates among female college athletes and nonathlete students. We predicted that athletes would have higher sIgA secretion rates than nonathletes and show greater declines in sIgA during the study period as intensive exercise training continued.MethodsWe recruited 52 female participants aged 18‐22 years (13 swimmers, 20 runners, and 19 nonathletes). We collected two saliva samples from each participant: baseline and a second sample 2 weeks later. Additionally, participants reported minutes of cardiovascular activity performed per week and completed a survey that included a modified Profile of Mood States and the Undergraduate Stress Questionnaire.ResultsWe found no significant differences in mean salivary sIgA secretion rates between athletes and nonathletes. Salivary sIgA significantly increased between sample collections for both groups, with nonathletes exhibiting a greater increase in sIgA than athletes. Cardiovascular activity was not associated with sIgA secretion rates. Illness status was a significant positive predictor of sIgA secretion rates.ConclusionsCardiovascular activity did not predict salivary sIgA secretion rates in this sample of female college students, and athletes did not show significantly different sIgA secretion rates than nonathletes. Together, these findings suggest that exercise may not be associated with altered immune function in well‐nourished college‐aged women. The increase in secretion rates among both athletes and nonathletes suggests that additional factors shared by both groups may have led to increases.

Published: February 2020

AbstractA rhodium complex catalyzed C−Se bond formation between diheteroaryl diselenides and acid fluorides in the presence of triphenylphosphine to provide heteroarylselenyl esters in good yields. The reaction was applicable to five‐ and six‐membered heteroaryl compounds. The heteroarylselenyl esters can be used as heteroaryselenating reagents in the synthesis of heteroaryl selenides, as shown by a platinum‐catalyzed addition reaction with 1‐octyne.
The “White Card” is grey: Survelliance, endurance and the Cashless Debit Card
Authors: Dalley Cameo 
Published: February 2020

AbstractIntroduced in 2016, the Cashless Debit Card (CDC) is part of a welfare policy trial designed to restrict and direct the expenditure of Aboriginal people receiving a range of government benefits. In this article, I explain that the CDC, also referred to as the “White Card,” appeases the concerns of non‐Aboriginal residents and broader Australia and that government is attempting to ameliorate Aboriginal dysfunction. I offer an account of income management in daily life from the perspective of those living with the Card in the East Kimberley town of Wyndham. I describe it as interconnected to a broader range of suite of government policies and enmeshed in broader social and political relations. Focused on participant observation and interviews undertaken with Wyndham residents in the period immediately after the introduction of the Card, this perspective is informed by longer‐term research in the region since 2013. I show that the Card acts as a quotidian form of disciplining surveillance against Aboriginal people. It is also a site of reinterpretation and rearticulation through the development of subversive practices by Aboriginal people, what I describe as the labour of endurance: Card holders are trying to endure its effects and manage its invasiveness into their lives.

Published: February 2020

AbstractPiezoelectric polymers, especially poly(vinylidene fluoride) (PVDF) are increasingly receiving interest as smart biomaterials for tissue engineering, energy harvesting, microfluidic, actuator, and biosensor applications. Despite possessing the greatest piezoelectric coefficients among all piezoelectric polymers, it is often desirable to increase the electrical outputs from PVDF for several of these applications. Blending with intrinsically conducting polymers (CP) in the form of nanofiber membranes is one of the facile methods to achieve the same. However, these polymers and their composites have so far been primarily investigated only for their physical property enhancements and in applications like energy storage while their biomedical applications and comparative assessment of their biocompatibility properties have not been yet explored. In this report, electrospinning of PVDF blends with polypyrrole (PPy), polyaniline (PANI), and a modified PANI with l‐glutamic acid (PANI‐LGA/P‐LGA) is performed to obtain different electrically active material membranes. The PVDF:CP composite nanofibers are compared with respect to their nanostructures, β‐phase content, and electrical conductivity. Further, biocompatibility of all the membranes was compared. It was found that incorporation of PPy, PANI, and P‐LGA increased the electrical conductivity of PVDF while the β‐phase content was also substantially enhanced. The highest biocompatibility with a pre‐osteoblast cell line (MC3T3) was exhibited in the order p‐LGA/PVDF > PANI/PVDF > PPy/PVDF, all being significantly higher than PVDF (p < .001). Although P‐LGA/PVDF showed higher electrical conductivity, biocompatibility with MC3T3, it was found to be highly cytotoxic to a HeLa (cancer) cell line. It is concluded that such structure property relations would help in selection of materials for specific biomaterial applications.

Published: February 2020

AbstractGarcinia mangostana Linn. or mangosteen is a tropical superfruit with an excellent taste. The peel and seed of mangosteen waste can be used in medical, cosmetic, and health‐care applications. Both mangosteen peel and seed have outstanding antibiotic properties and are suitable for use as bio‐fillers in natural rubber latex products such as medical gloves, rubber transdermal patches, rubber toys, and rubber‐health care products. In addition, mangosteen seed composed of griseofulvin polyethylene glycol [(C2H4O2)n]1‐x (C17H17ClO6)x is useful for treating osteoarthritis of the knee, similar to commercial glucosamine (amino sugar). Adding mangosteen peel and mangosteen seed in rubber gloves and rubber patches, respectively, is an alternative form of antimicrobial and drug delivery replacing taking a tablet. This study compared the characteristics and properties of mangosteen peel with silver nitrate (AgNO3) and compared the characteristics and properties of mangosteen seed with commercial glucosamine using the film casting dipping process. The obtained natural rubber latex gloves with added mangosteen peel powder had a good appearance with a high contact angle (resulting in hydrophobicity and low wettability with water equal to 130.67° ± 2.08°), good mechanical properties (high percentage of elongation at break 815.72 ± 54.67%, high tensile strength 64.59 ± 13.54 MPa, good stiffness 296.50 ± 48.32 N/m, and high Young's modulus 29.65 ± 4.83 MPa), and as it was non‐toxic to skin it was suitable for application in medical gloves and transdermal patches. The natural rubber patches added with mangosteen seed had high wettability and good mechanical properties. The Fourier‐transform infrared (FTIR) spectra of mangosteen seed were consistent with the FTIR spectra of commercial glucosamine.
Fault tolerant control for joint structure in PEMS high speed maglev train
Authors: Wang Zhiqiang , Long Zhiqiang , Li Xiaolong 
Published: February 2020

AbstractThe PEMS high speed maglev train, which features a permanent magnet inside an electromagnet, is a new kind of maglev train for long distance intercity transportation. The joint structure, which consists of two single levitation sub‐systems, is the fundamental levitation unit. Two kinds of faults are considered and corresponding fault tolerant control strategies are proposed. The first fault condition is when a gap sensor that is part of a single levitation system is faulty. For this kind of fault, a fault tolerant control strategy based on signal reconfiguration is proposed. The second fault condition is when the whole of a single levitation sub‐system is faulty. Under this condition, a faulty model is firstly established, then a fault tolerant control strategy is designed. When this kind of fault is detected, a switch from the normal controller to the fault tolerant controller can make the faulty system stable.

Published: February 2020

AbstractWe report the case of a 14‐year‐old girl that was referred to the maxillo facial surgery unit at age 11 years because she exhibited swelling in the right side of her maxilla and right mandible. After a conservative surgery, she started with interferon alpha‐2a to avoid recurrence. She has remained in treatment with successful results during her follow up. Considerable reduction of both maxilla and mandible lesions and bone fill have been documented. In addition, her clinical history and phenotype were suggestive of Noonan syndrome. She has short stature, broad and short neck; hypertelorism (increased distance between the eyes); downslanting palpebral fissures; sparse eyebrows and eyelashes; posteriorly rotated ears with fleshy lobes; follicular keratosis over the face, and developmental delay. Her karyotype was 46, XX. Molecular analysis of RAS/MAPK pathway genes showed a SOS1 amino acid substitution of arginine to lysine at position 552 (p.R552K). This case presents the infrequent condition of Noonan syndrome with multiple giant cell lesions (NS/MGCL) that would be the first patient as far as we know treated with surgery and interferon alpha‐2a for her giant cell lesions.

AbstractIntroductionThe association between prediabetes and functional outcome in cerebrovascular diseases is controversial. No study has explored the relationship between prediabetes and functional outcome in intracerebral hemorrhage patients. Our study aimed to explore the association between prediabetes and functional outcome in intracerebral hemorrhage patients 1 month poststroke.MethodsOne hundred and fifty intracerebral hemorrhage patients were consecutively recruited within the first 24 hr after admission and were followed up for 1 month. Patients were divided into a diabetes mellitus group, a prediabetes group, and a nondiabetic group by fasting glucose levels, 2‐hr postprandial blood glucose levels, and glycosylated hemoglobin levels. Patients with modified Rankin Scale scores >2 at 1 month were defined as having a poor functional outcome.ResultsThe prediabetes group had a higher risk of poor functional outcome than the nondiabetic group in intracerebral hemorrhage patients (37.9% vs. 9.8%, χ2 = 11.521, p = .001). According to the logistic regression analyses, prediabetes was associated with a poor functional outcome in intracerebral hemorrhage patients after adjusting for confounding factors (odds ratio = 6.167, 95% confidence interval = 1.403–27.102, p = .016).ConclusionsOur findings show that prediabetes is associated with a poor functional outcome in intracerebral hemorrhage patients 1 month poststroke.
Why does eco‐innovation differ in service firms? Some insights from Spain
Authors: Jové‐Llopis Elisenda , Segarra‐Blasco Agustí 
Published: February 2020

AbstractAlthough environmental innovation studies have traditionally focused on manufacturing firms, the distinctive features of eco‐innovation activities carried out by service firms require special attention. Using the Spanish Commumity Innovation Survey (CIS), this paper determines which are the main drivers of undertaking eco‐innovation and investigates the similarities and differences between service and manufacturing firms within the five sub‐groups of services (supplier dominated, scale intensive physical networks, scale intensive information networks, science‐based, and others). The results confirm that the main eco‐innovation triggers are similar—technological push factor orientation (internal R&D and persistence) and firm size—while the impact of market pull factors and public environmental legislation differ within the services sub‐groups. In addition, we find a high degree of heterogeneity within service firms. In contrast to traditional service firms, those in the groups involving R&D activities, information networks, and scale‐intensive physical networks exhibit intensive eco‐innovation performance and show a high level of green indicators.
Behavioral health indicators and time‐to‐rearrest in an adult pre‐arrest diversion program
Authors: Kopak Albert M. 
Published: February 2020

AbstractSeveral states have recently adopted legislation in support of pre‐arrest diversion programs that give police the authority to refer adults with behavioral health needs to treatment providers instead of placing them under arrest and booking them into local jails. The Adult Civil Citation program has been operating since 2013 to divert adults accused for the first time of a misdemeanor offense to a community behavioral health provider with the primary goal of addressing underlying needs that are likely to be associated with future criminal justice contact. The current study analyzed data from a sample of 1,071 adults who participated in the program to assess the impact of behavioral health indicators on time‐to‐rearrest. Adults who presented greater behavioral health needs were more likely to come into subsequent contact with police, but these indications did not influence the amount of time that lapsed between program participation and rearrest events.

Published: February 2020

AbstractIntroductionKnowledge of the stress distribution on structures around the sacroiliac joint (SIJ) is required to treat or prevent SIJ disorders. The purpose of this study was to reveal the association between sacral morphology and SIJ conformity.Materials and methodsThis cross‐sectional study included 11 adult patients with unilateral SIJ pain who underwent computed tomography (CT) imaging of the pelvis. Bony coordinate systems for the sacrum and innominates were embedded using anatomical landmarks. Local coordinate systems for the auricular surfaces of the sacrum and innominate were also defined. Conformity of the SIJ was quantified by the offset of the coordinate systems between the auricular surfaces of the sacrum and innominate. Repeated measure ANOVA and multiple regression analysis were used for statistical analyses.ResultsThere were large variations across subjects in sacral morphology and SIJ conformity. There were no differences in any of the six degrees‐of‐freedom positions or orientations of the bilateral sacral and innominate auricular surfaces between the symptomatic and asymptomatic sides. The SIJ downward rotation on the asymptomatic and symptomatic sides were 0.0 [−1.0, 1.1]° and 2.1 [1.2, 3.0]°, respectively. Smaller downward rotation of the sacral auricular surface based on the sacral bony coordinate system had significant association with the greater SIJ downward rotation (standard partial regression coefficient: −.44, p = .043).ConclusionsThe results indicate that the morphology of the sacrum is associated with poor SIJ conformity and that separation of the superior portion of the SIJ can be a risk factor for SIJ pain.

Published: February 2020

Long noncoding RNAs have been proved in regulating tumourigenesis, including hepatocellular carcinoma (HCC). However, up to date, the role of PCAT6 in HCC is rare to be reported. In current study, bioinformatics analysis and quantitative real‐time PCR were applied to examine the expression of PCAT6 in HCC. The role of PCAT6 in cell proliferation, cell cycle arrest, apoptosis, and metastasis were detected in both gain‐ and loss‐of‐function studies by cell biological assays. Bioinformatics analysis was employed to investigate the PCAT6‐related genes and pathways in HCC. And we found that PCAT6 was significantly upregulated in HCC tissues and correlated with poor overall survival and disease‐free survival in HCC patients. Furthermore, elevated PCAT6 promoted cell proliferation, inhibited cell cycle arrest and cell apoptosis while deficiency of PCAT6 impaired cell proliferation, caused cell cycle arrest and induced cell apoptosis of HCC. Moreover, as for bioinformatics analysis, a total of 389 PCAT6‐related genes were found in both HCC tissue and cell lines, and these promising target genes were highly enriched in various key pathways, such as Wnt, HIF‐1 signalling pathway, and metabolic pathways. Additionally, among these genes, DCAF13, SNRPB2, RPS8, and FKBP1A were revealed to be overexpressed in HCC and predicted poor prognosis. Taken together, our findings illustrate that PCAT6 contributes to HCC progression and might be a potential target for HCC therapy. Bioinformatics analysis may present a new way for assessing the underlying mechanism of PCAT6 in HCC.Significance of the StudyHepatocellular carcinoma (HCC) is one of the most common and malignant tumours all over the world. In this study, we observed that PCAT6 was upregulated in HCC and correlated with poor prognosis of HCC patients. PCAT6 could promote cell proliferation, inhibit cell cycle arrest and cell apoptosis of HCC, suggesting PCAT6 exerts tumorigenic role in HCC. Moreover, bioinformatics analysis revealed a total of 389 PCAT6‐related genes in both HCC tissue and cell lines, and these promising target genes were highly enriched in various key pathways, such as Wnt, HIF‐1 signalling pathway, and metabolic pathways. These finding provided evidence that PACT6 may be identified as a strategy to treat HCC in the future.

Published: February 2020

AbstractThe new MitraClip G4 device (Abbott Vascular) has been recently approved by Food and Drug Administration and is currently in limited release. A patient with a large mitral regurgitation (MR) jet but a relatively small mitral valve area (MVA) was not a surgical repair candidate nor an optimal MitraClip third‐generation device candidate. Therefore, we implanted the new G4 NTW device that resulted in significant MR reduction with a 57% reduction in MVA. To our knowledge, this is the first reported clinical use of the MitraClip G4 NTW device. We find that it may provide better results than a single NTR device and less reduction in MVA than two older generation devices. Further experience is needed to optimize patient selection for the four new G4 devices available.
