AbstractLithium borate (LB) glasses doped with dysprosium oxide (Dy2O3) have been prepared by utilizing the conventional melt‐quench technique. The prepared glass samples were exposed to 60Co to check their dosimetric features and kinetic parameters. These features involve glow curves, annealing, fading, reproducibility, minimum detectable dose (MDD), and effective atomic number (Zeff). Kinetic parameters including the frequency factors and activation energy were also determined using three methods (glow curve analysis, initial rise, and peak shape method) and were thoroughly interpreted. In addition, the incorporation of Dy impurities into LB enhanced the thermoluminescence sensitivity ~170 times. The glow from LB:Dy appeared as a single prominent peak at 190°C. The best annealing proceeding was obtained at 300°C for 30 min. Signal stability was reported for a period of 1 and 3 months with a reduction of 26% and 31%, respectively. The proposed glass samples showed promising dosimeter properties that can be recommended for personal radiation monitoring.

AbstractBased on the currently available literature, total denervation of the elbow joint is considered impossible. However, consensus with respect to the anatomic location of sensory branches is lacking. The aim of this literature review was to establish consensus with respect to the anatomic features of the articular branches innervating the elbow joint, as well as the distribution of sensory receptors about its capsule. Four electronic databases were queried, between January 1945 and June 2019. Twenty‐one original articles providing a detailed description of the distribution of sensory receptors about the elbow joint capsule (5) and its articular branches (16) were reviewed. The posterior capsule was found to be primarily innervated by the ulnar and radial nerves via combined articular branches and sensory branches of the medial antebrachial cutaneous nerve. The anterior capsule was found to be primarily innervated by a plexus of articular ramifications from muscular branches of mixed nerves (ulnar, musculocutaneous, radial, and median nerves). A higher density of nociceptors and mechano‐receptors was identified within the posterior and anterior capsules, respectively. Thorough denervation, via the technique proposed herein, is likely to be sufficient in eliminating pain from degenerative conditions of the elbow joint.

AbstractIntroductionThere are many variations of scapula morphology. Evaluation of scapula morphology is necessary to elucidate shoulder joint movement. We aimed to analyze the bone morphology of various parts constituting the scapula to identify certain conserved features among them.Materials and MethodsThirty‐one healthy individuals were the subjects. We created a scapular three‐dimensional (3D) model using computed tomography (CT). X and Y axes were set on a glenoid surface. We measured the approximate plane of the upper and lower scapular bodies and scapular spine and the central axis of the coracoid and acromion. The anatomical position of the scapular spine, upper and lower bodies, coracoid, and acromion was measured. The positional relationship between the upper and lower bodies and scapular spine and the coracoid and acromion was evaluated. The average angle of the upper and lower scapular bodies and the scapular spine with respect to the XZ plane was calculated. The average angle of the coracoid and acromion with the X‐axis on the XY plane and Z‐axis on the YZ plane was calculated.ResultsOn the XY plane, approximate planes of the upper and lower part of the body and the scapular spine were significantly correlated to each inclination. On the XY plane, inclinations of the central axes of the coracoid and acromion were significantly correlated.ConclusionsThe findings revealed for the first time the correlation between the inclinations of the scapular body and scapular spine and the inclination angle between the coracoid and acromion.

AbstractBackgroundResidual stent strut thrombosis after primary percutaneous coronary intervention (PCI), negatively affects myocardial perfusion, may increase stent thrombosis risk, and it is associated with neointima hyperplasia at follow‐up.ObjectivesTo study the effectiveness of any bivalirudin infusion versus unfractionated heparin (UFH) infusion in reducing residual stent strut thrombosis in patients with ST‐elevation myocardial infarction (STEMI).MethodsMulti‐vessel STEMI patients undergoing primary PCI and requiring staged intervention were selected among those randomly allocated to two different bivalirudin infusion regimens in the MATRIX (Minimizing Adverse Haemorrhagic Events by TRansradial Access Site and angioX) Treatment‐Duration study. Those receiving heparin only were enrolled into a registry arm.Optical coherence tomography (OCT) of the infarct‐related artery was performed at the end of primary PCI and 3–5 days thereafter during a staged intervention. The primary endpoint was the change in minimum flow area (ΔMinFA) defined as (stent area + incomplete stent apposition [ISA] area) − (intraluminal defect + tissue prolapsed area) between the index and staged PCI.Results123 patients in bivalirudin arm and 28 patients in the UFH arm were included. Mean stent area, percentage of malapposed struts, and mean percent thrombotic area were comparable after index or staged PCI. The ΔMinFA in the bivalirudin group was 0.25 versus 0.05 mm2 in the UFH group, which resulted in a between‐group significant difference of 0.36 [95% CI: (0.05, 0.71); p = .02]. This was mostly related to a decrease in tissue protrusion in the bivalirudin group (p = .03). There was a trend towards more patients in the bivalirudin group who achieved a 5% difference in the percentage of OCT frames with the area >5% (p = .057).ConclusionsThe administration of bivalirudin after primary PCI significantly reduces residual stent strut thrombosis when compared to UFH. This observation should be considered hypothesis‐generating since the heparin‐treated patients were not randomly allocated.

Published: December 2019

AbstractSelective hydrogenation of alkynes to alkenes (semihydrogenation) without the use of a poison and H2 is challenging because alkenes are easily hydrogenated to alkanes. In this study, a titanium (IV) oxide photocatalyst having Pd core‐Cu shell nanoparticles (Pd@Cu/TiO2) was prepared by using the two‐step photodeposition method, and Pd@Cu/TiO2 samples having various Cu contents were characterized by electron transmission microscopy, X‐ray photoelectron spectroscopy and UV‐vis spectroscopy. Thus‐prepared Pd@Cu/TiO2 samples were used for photocatalytic hydrogenation of 4‐octyne in alcohol and the catalytic properties were compared with those of Pd/TiO2 and Cu/TiO2. 4‐Octyne was fully hydrogenated to octane over Pd/TiO2 at a high rate and 4‐octyne was semihydrogenated to cis‐4‐octene over Cu/TiO2 at a low rate. Rapid semihydrogenation of 4‐octyne was achieved over Pd(0.2 mol%)@Cu(1.0 mol%)/TiO2, indicating that the Pd core greatly activated the Cu shell that acted as reaction sites. A slight increase in the reaction temperature greatly increased the rate with a suppressed rate of H2 evolution as the side reaction. Changes in the reaction rates of the main and side reactions are discussed on the basis of results of kinetic studies. Reusability and expandability of Pd@Cu/TiO2 in semihydrogenation are also discussed.

AbstractThe abnormal expression of sialic acid (SA) on the cell surface or in bodily fluids has been proven to correlate with several diseases. An electrochemical approach has been developed for the sensitive and accurate determination of SA in human serum samples. Gold nanodendrites (AuNDs) electrodeposited on a carbon cloth (CC) electrode were utilized as the substrate electrode and provided high surface area and conductivity. The thiolated nucleic acid aptamer of SA was immobilized and recognized SA specifically, followed by the attachment of the nanocomposite of gold nanoparticles with 4‐mercaptophenylboric acid and thionine (MPBA−AuNP−Th) via boronic acid‐diol binding. An amplified signal by the electrochemical reduction of Th could be obtained because of high conductivity of substrate and high loading of Th on AuNPs. The proposed sensor exhibited remarkable selectivity and high sensitivity with a low detection limit of 60 nM, owing to the high affinity of aptamer and the signal amplification strategy, respectively. The feasibility of the aptasensor was verified by evaluation of SA level in human serum.
A field‐split preconditioning technique for fluid‐structure interaction problems with applications in biomechanics
Authors: Calandrini Sara , Aulisa Eugenio , Ke Guoyi 
Published: December 2019

AbstractWe present a novel preconditioning technique for Krylov subspace algorithms to solve fluid‐structure interaction (FSI) linearized systems arising from finite element discretizations. An outer Krylov subspace solver preconditioned with a geometric multigrid (GMG) algorithm is used, where for the multigrid level subsolvers, a field‐split (FS) preconditioner is proposed. The block structure of the FS preconditioner is derived using the physical variables as splitting strategy. To solve the subsystems originated by the FS preconditioning, an additive Schwarz (AS) block strategy is employed. The proposed FS preconditioner is tested on biomedical FSI applications. Both 2D and 3D simulations are carried out considering aneurysm and venous valve geometries. The performance of the FS preconditioner is compared with that of a second preconditioner of pure domain decomposition type.

AbstractNickel‐rich layered oxides have developed into appealing cathode materials for lithium‐ion batteries in recent years for the sake of high energy density and low cost, but they suffer from severe capacity deterioration during long‐term cycling. Herein, Mn‐doped nickel‐rich Li(Ni0.88Co0.09Al0.03)1‐δMnδO2 (δ=0, 0.01, 0.02) cathode materials with a nanoscale NixMn1−xO‐type pillar layer are synthesized using a facile high‐shear dry mixing and high‐temperature calcination process in this study. The as‐fabricated M0.01−NCA electrode with a NixMn1−xO‐type layer about 20 nm exhibits excellent cycle performance compared with the pristine in coin‐cells and in pouch cells (the long‐term cycle number is four times that of the pristine). Detailed investigation of the fading mechanism is performed by HRTEM, ex‐situ XRD, XPS et al. The enhanced performance is directly related to the synergetic effects of bulk inactive Mn4+ doping and the increased nanoscale NixMn1−xO‐type pillar layer. The Mn dopants stabilize the lattice structure thus decreasing the microcracks, and the pillar layer protects the cathode from parasitic reactions with electrolytes during long‐term cycling. This work gives a new insight into the role of Mn doping on the enhanced structure of nickel‐rich layered oxides.
Parallel time series join using spark
Authors: Rong Chuitian , Chen Lili , Silva Yasin N. 
Published: December 2019

SummaryA time series is a sequence of data points in successive temporal order. Time series data is produced in many applications scenarios, and the techniques for its analysis have generated substantial interest. Time series join is a primitive operation that retrieves all pairs of correlated subsequences from two given time series. As the Pearson correlation coefficient, a measure of the correlation between two variables, has multiple beneficial mathematical properties, for example, the fact that it is invariant with respect to scale and offset, it is used to measure the correlation between two time series. Considering the need to analyze big time series data, we focus on the study of scalable and distributed techniques to process massive data sets. Specifically, we propose a parallel approach to perform time series joins using Spark, a popular analytics engine for large‐scale data processing. Our solution builds on (1) a fast method to compute the fast Fourier transform on the times series to calculate the correlation between two time series, (2) a lossless partition method to divide the time series into multiple subsequences and enable a parallel and correct computation of the join result, and (3) optimization techniques to avoid redundant computations. We performed extensive tests and showed that the proposed approach is efficient and scalable across different data sets and test configurations.
Priority‐based online flow scheduling for network throughput maximization in software defined networking
Authors: Liu Liang , Guo Songtao , Liu Guiyan , Zeng Yue 
Published: December 2019

SummaryData transmission in current networks is usually associated with strict priority enforcement for the purpose of quality of service (QoS). Under the case that priority flow requests are injected into the network sequentially without the information of future flow request arrivals, it is a challenging to achieve network throughput maximization for on‐line flow requests under the joint constraints of the flow's priority, bandwidth demand, and resource capacity. Software Defined Networking (SDN) can effectively solve the flow scheduling equilibrium problem between the priority of dynamic flow requests and the maximization of network throughput. Therefore, in this paper, we study on‐line flow request admission in SDN, the goal of which is to maximize the network throughput under the constraints of critical network bandwidth resources, flow priority, and bandwidth demands. First, we present the concept of flow routing cost and profit and a model to characterize the cost of using link resources and routing paths. Then, we propose an efficient on‐line priority flow scheduling algorithm (OPFSA) to solve priority flow request scheduling problem and analyze the competitive ratio of OPFSA. Our on‐line algorithm can reach throughput within
of the highest possible throughput that can be achieved by an off‐line algorithm, where n is the number of node in the network. Finally, experimental results demonstrate that compared with SHORTEST‐SC, our proposed algorithm can enhance the cumulative bandwidth about 9% and 40% when general network size is 30 and 170 nodes, respectively, and improve the throughput about 25% in Fat‐tree network when pod size is 4.

AbstractObjectivesThis study aimed to clarify the relationship between physical performance and oral function in older women participating in community‐based physical and oral exercise programs.Material and methodsWe included 163 older women (mean age: 77.4 ± 8.6 years) who participated in weekly health programs in Takehara City, Hiroshima Prefecture, Japan, from August to December 2018. Physical fitness was assessed using a handgrip strength test, a timed up and go test, a one‐leg standing time with eyes open test, and a 30‐s chair stand test (CS‐30). Tongue pressure, oral diadochokinesis, and dysphagia risk assessment for the community‐dwelling elderly were used to assess oral function.ResultsParticipants were divided into women aged 65–74 years (younger group) and those aged ≥75 years (older group). There was no significant difference in oral function measures between the groups. A significant correlation was found between CS‐30 and oral diadochokinesis for /pa/, /ta/, and /ka/ (Spearman's rank correlation; /pa/: r = .234, p = .009; /ta/: r = .299, p = .001; and /ka/: r = .283, p = .002) in the older group. Multivariable analysis revealed a significant positive relationship between CS‐30 and /ta/ repetition in the older group (p = .016).ConclusionsOral function (i.e., tongue motor function) may be associated with physical performance (i.e., lower leg muscle strength) in women aged ≥75 years. Further study is necessary to clarify sex differences in oral function deterioration.
Market differentiation threshold and the relationship between corporate social responsibility and corporate financial performance
Authors: Lin Woon Leong , Law Siong Hook , Azman‐Saini W. N. W. 
Published: December 2019

AbstractThis study assesses the impact of corporate social responsibility (CSR) on corporate financial performance (CFP) by using an innovative threshold estimation technique. We examine whether the CSR effect on CFP is varied with the distinct levels of market differentiation. The empirical analysis is based on a world automotive panel dataset for the period of 2011–2017. We unveil an inverted V‐shaped relationship between CSR and CFP and confirm that the increasing nonparametric regression line up to a certain threshold level indicates a positive effect on CFP, whereas a decreasing line indicates a negative effect. Hence, these findings support the idea that engagement in CSR can boost firm performance by incorporating with market differentiation, since higher firm performance is associated with strong differentiation (i.e., less substitutability), but CSR may not provide large benefits in firms with too high market differentiation.

AbstractBackgroundEndobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA) is a minimally invasive, reliable technique for sampling mediastinal lymph nodes (LNs). Liquid‐based cytology (LBC) is widely used for cervical cancer screening because it provides reliable and feasible results. The present study aimed to evaluate effectiveness of the combination of EBUS‐TBNA and LBC in the diagnosis of mediastinal lymphadenopathy.MethodsA total of 602 LNs that were retrospectively analyzed were sampled in 442 patients who underwent EBUS‐TBNA between January 2014 and December 2016. The histopathological result of TBNA tissue or cell blocks was considered as the gold standard to evaluate diagnostic utility of LBC and conventional smears (CS) for the diagnosis of mediastinal lymphadenopathy.ResultsOf the 602 LNs, 265 were mediastinal LN metastases from lung cancer, four were lymphoma, and 333 were benign. The sensitivity of LBC and CS in the diagnosis of mediastinal LN metastases from lung cancer was 72.8% and 63%, respectively, and the specificity was 98.5% and 97%, respectively. The positive predictive values for LBC and CS were 97.5% and 94.4%, respectively, whereas the negative predictive values were 82.2% and 76.9%, respectively. The accuracy of LBC and CS was 88% and 83.7%, respectively. The diagnostic value of LBC was significantly higher than that of CS (P = .001).ConclusionsThe combination of EBUS‐TBNA and LBC is a highly reliable and feasible procedure that optimizes diagnostic utility for the diagnosis of lung cancer and mediastinal LN staging.

AimsIron deficiency (ID) is a common co‐morbidity in heart failure (HF), associated with impaired functional capacity, poor quality of life and increased morbidity and mortality. Treatment with intravenous (i.v.) ferric carboxymaltose (FCM) has shown improvements in functional capacity, symptoms and quality of life in stable HF patients with reduced ejection fraction. The effect of i.v. iron supplementation on morbidity and mortality in patients hospitalised for acute HF (AHF) and who have ID has yet to be established. The objective of the present article is to present the rationale and design of the AFFIRM‐AHF trial (ClinicalTrials.gov NCT02937454) which will investigate the effect of i.v. FCM (vs. placebo) on recurrent HF hospitalisations and cardiovascular (CV) mortality in iron‐deficient patients hospitalised for AHF.MethodsAFFIRM‐AHF is a multicentre, randomised (1:1), double‐blind, placebo‐controlled trial which recruited 1100 patients hospitalised for AHF and who had iron deficiency ID defined as serum ferritin <100 ng/mL or 100–299 ng/mL if transferrin saturation <20%. Eligible patients were randomised (1:1) to either i.v. FCM or placebo and received the first dose of study treatment just prior to discharge for the index hospitalisation. Patients will be followed for 52 weeks. The primary outcome is the composite of recurrent HF hospitalisations and CV mortality. The main secondary outcomes include the composite of recurrent CV hospitalisations and CV mortality, recurrent HF hospitalisations and safety‐related outcomes.ConclusionThe AFFIRM‐AHF trial will evaluate, compared to placebo, the effect of i.v. FCM on morbidity and mortality in iron‐deficient patients hospitalised for AHF.
