A Siamese network framework for bank intelligent Q&A prediction
Authors: Wei Wei , Liang Yingli 
Published: June 2022

AbstractWith the development of financial technologies and the explosive growth of data, the intelligent customer services have attracted a considerable attention of academic and industrial experts. The calculation of question similarity has become a key to the question and answer (Q&A) of financial intelligent customer service. In this work, we propose a Siamese network called W2V‐Siamese‐BiLSTM for bank Q&A prediction. Based on the Word2vec text information vectorization, the pre‐training model of embedding layer is established, and two bidirectional long short‐term memory (Bi‐LSTM) networks are introduced to encode the upper layer input. The weights are shared in the encoding layer, and finally the Manhattan distance is used in the similarity calculation layer. The experimental results show that the supervised similarity calculation framework proposed in this work has good applicability in real financial Q&A. The accuracy of the proposed method is 81.2%. The analysis further highlights the effectiveness and superiority of supervised learning models in the financial field.
Is turnover intention static or dynamic? The impacts of inter‐role conflicts and psychological workplace strain on turnover intention trajectories
Authors: Jeong Shinhee , Lee Yunsoo 
Published: June 2022

AbstractThe purpose of the present study is to identify the growth trajectories of employees' turnover intention using growth mixture modeling. We utilized work, family, and health study (WFHS) data consisting of repeatedly measured data of employees from an extended‐care company (n = 799). We identified three profiles (i.e., Low‐flat profile, Steadily increasing profile, and High‐flat profile) that exhibit distinct patterns of change. Using multinomial logistic analysis, we also investigated the associations between the identified profiles and inter‐role conflict (i.e., work‐life conflict and life‐work conflict), psychological workplace strain (i.e., perceived stress and emotional exhaustion), and socio‐demographic characteristics (i.e., gender, age, tenure, and education). Finally, we examined the mean differences in the variables among the three profiles. Based on these results, we suggest theoretical and practical implications related to turnover intention.

Authors: Özbek Oguz , Isildak Ömer 
Published: June 2022

AbstractA novel poly(vinyl chloride; PVC) membrane‐based Cu(II)–selective sensor has been developed using synthesized 5,10,15,20‐tetrakis(4‐methoxycarbonylphenyl)porphyrin as an ionophore. The Cu(II)–selective sensor exhibits a Nernstian response for Cu(II) ion over a wide concentration range of 1.0 × 10−5to 1.0 × 10−1 mol L−1with the slope of 27.0 ± 2.5 mV/decade, and a lower limit of detection of 1.88 × 10−6 mol L−1. The novel sensor shows good repeatability and high selectivity for Cu(II) ions over other mono‐, bi‐ and trivalent cations. The sensor potential response remains unaffected by pH in the range of 4.4–10.6 and exhibits a fast response time of less than 10s. Finally the developed Cu(II)–selective sensor has been successfully used as an indicator electrode in the potentiometric titration of Cu2+against ethylenediaminetetraacetic acid and also in the determination of Cu(II) ion concentration in different water and beverage samples.

Published: June 2022

AbstractArticular fracture malreduction increases posttraumatic osteoarthritis (PTOA) risk by elevating joint contact stress. A new biomechanical guidance system (BGS) that provides intraoperative assessment of articular fracture reduction and joint contact stress based solely on a preoperative computed tomography (CT) and intraoperative fluoroscopy may facilitate better fracture reduction. The objective of this proof‐of‐concept cadaveric study was to test this premise while characterizing BGS performance. Articular tibia plafond fractures were created in five cadaveric ankles. CT scans were obtained to provide digital models. Indirect reduction was performed in a simulated operating room once with and once without BGS guidance. CT scans after fixation provided models of the reduced ankles for assessing reduction accuracy, joint contact stresses, and BGS accuracy. BGS was utilized 4.8 ± 1.3 (mean ± SD) times per procedure, increasing operative time by 10 min (39%), and the number of fluoroscopy images by 31 (17%). Errors in BGS reduction assessment compared to CT‐derived models were 0.45 ± 0.57 mm in translation and 2.0 ± 2.5° in rotation. For the four ankles that were successfully reduced and fixed, associated absolute errors in computed mean and maximum contact stress were 0.40 ± 0.40 and 0.96 ± 1.12 MPa, respectively. BGS reduced mean and maximum contact stress by 1.1 and 2.6 MPa, respectively. BGS thus improved the accuracy of articular fracture reduction and significantly reduced contact stress. Statement of Clinical Significance: Malreduction of articular fractures is known to lead to PTOA. The BGS described in this work has potential to improve quality of articular fracture reduction and clinical outcomes for patients with a tibia plafond fracture.

ObjectivesTo investigate ultrasound appearance and the survival outcomes for patients with primary thyroid lymphoma (PTL).MethodsUltrasonic images and clinical characteristics from pathologically confirmed 69 PTL patients (2008–2019) were retrospectively analyzed. The clinical characteristics, ultrasonic characters, and prognostic factors were analyzed. Survival curves were plotted using the Kaplan–Meier method. Univariate and multivariate analyses were performed.ResultsOf the 69 study patients, 23 were indolent PTL and 46 were aggressive PTL. Age (>70 years old) and elevated lactate dehydrogenase levels were statistically different clinical features between aggressive and indolent PTL. From ultrasonic images, 34 cases were nodular, 11 diffuse, and 24 mixed pattern. Mixed types displayed high invasiveness (45.7%) while diffuse types displayed higher inertness (39.1%), with statistically significant differences (P = .000). Invaded thyroid capsule and increased chaotic vascularity also showed significant differences between aggressive and indolent PTL. We also observed statistical difference in overall survival rates between aggressive and indolent PTL (P = .032). Single factor K‐M analyses showed that age >70 years, aggressive pathology, and Ki67 >30% were positively correlated with the risk of poor PTL survival (P < .05).ConclusionsMultimodal ultrasound provides accurate ultrasonographic information and facilitates PTL invasiveness diagnostics for improved clinical treatment. In addition, PTL patients aged >70 years, with aggressive pathology, and Ki67 >30% were more likely to have a poor survival outcome.

Published: June 2022

AbstractProducing lubricating base oils from coal‐based chemicals is an alternative route for replacing the conventional petro‐based lubricants. Herein, we firstly reported the synthesis of high‐viscosity polyalkylphenanthrene oils derived from the coal‐based chemicals (phenanthrene, C6/C8‐olefins) by alkylation with acidic ionic liquid (Et3NHCl∙2AlCl3) as catalyst. Their primary physicochemical properties were studied in detail to reveal their structure–property relationships, the existence of the phenanthrene ring in their molecular structure led to some good property, such as high‐kinematic viscosity (12.6–30.2 mm2·s−1 at 100°C), better flash point (>230°C), high‐oxidative onset time (>230°C) and good polarity. Moreover, the tribological performances of the synthetic oils and the commercial PAO‐20 lubricating base oil were studied for comparison, these alkylated phenanthrenes, especially PHP‐3 and POP‐3, exhibited much higher load‐carrying capacity, reducing friction and anti‐wear property than that observed on PAO‐20.
Splitting proximate algorithm for deformable image registration based on functions of bounded deformation
Authors: Li Chen , Nie Ziwei , Yang Xiaoping 
Published: June 2022

AbstractBackgroundDeformable image registration is a crucial task in the field of medical image analysis. Functions of bounded deformation (BD) have been proved effective for modeling the displacement fields between medical images since they can capture the discontinuity of displacement fields along edges of organs and tissues.PurposeHowever, we find that at the same time, BD functions‐based models tend to obtain discontinuous displacement fields inside the regions of organs and tissues due to image noises in some cases and the presented gradient descent algorithm is time‐consuming. To alleviate these problems, we propose a faster algorithm named SPA: splitting proximate algorithm.MethodsIn the framework of variable‐splitting scheme, we incorporate a proximal term in the deformable registration energy based on functions of BD.ResultsThe proposed algorithm can efficiently solve the original model and obtain displacement fields, which look more natural and plausible. Numerical experiments show the effectiveness and stability of the proposed algorithm.ConclusionsThe proposed SPA is able to drastically register the images with a plausible deformation field and not sensitive to noise.
In service to the sultan: Biological affinity analysis of Vlach Ottoman vassals from the Šarić Struga and Koprivno‐Križ sites in southern Croatia

Published: June 2022

AbstractAs a cultural isolate and historically labeled ethnicity, the extent of biological divergence between Vlachs and non‐Vlachs in Southeast Europe is not well understood. Here, we present a comparison of metric and non‐metric cranial morphology designed to investigate the degree to which a Vlach sample (n = 32) from the Ottoman period in southern Croatia is biologically differentiated from non‐Vlach communities. By calculating Relethford–Blangero distances using cranial measurements and conducting a mean measure of divergence test based on cranial non‐metric traits, we investigated morphological relationships between the Vlach sample and other regional samples. Results from both metric and non‐metric analyses indicate a close biological relationship with the non‐Vlach community who lived nearby. Lacking substantial differences from the local non‐Vlach community, the Vlach ethnicity may have been distinct based on socioeconomic rather than biological factors. This research points to an ethnogenesis more cultural than biological for this historical context.
Optimal group consensus control for the second‐order agents in the coopetition networks via adaptive dynamic programming and event‐triggered methods
Authors: Ji Lianghao , Li Xi , Zhang Cuijuan , Xiao Yunpeng , Li Huaqing 
Published: June 2022

AbstractThis article investigates the optimal group consensus control problem for the second‐order multi‐agent systems by using event‐triggered and adaptive dynamic programming methods. The proposed method only uses the interaction information among the agents. Comprehensively considering the coopetition coupling interactions among the agents, a novel tracking error function is addressed for meeting the requirement of group consensus. On this basis, we use the Bellman optimality principle to formulate the optimal group consensus problem. To implement the proposed method, the actor–critic neural networks are used to approximate the iterative performance index functions and the control policies in real time. Meanwhile, the event‐triggered condition with filter function is installed for each agent to reduce the control cost. Therefore, the weights of actor–critic networks are updated only at the event‐triggered instants. The weight estimation errors and the control policy estimation errors are proved uniformly ultimately bounded and the Zeno behavior in the system can be avoided. Finally, the comparative simulation results show that the proposed method can greatly reduce the update times of the control policy of the system.

Published: June 2022

AbstractTo provide the standard of psychosocial care for children with cancer and hematological disorders and their families, multidisciplinary teams must clearly define their scope and collaborate in ways that optimize the quality and efficiency of care. A new organizational structure was leveraged to delineate roles and scope for each psychosocial discipline at our institution. We developed a document, the scope of psychosocial care (SPC), that serves as a platform for making patient care decisions and provides opportunities for the reevaluation of programming. Herein, we present the process and outcome of the SPC and make recommendations for identifying roles in pediatric psychosocial hematology‐oncology.

Published: June 2022

AbstractObjectiveNoninvasive respiratory support has reduced the need for mechanical ventilation and surfactant administration in very premature neonates. We sought to determine how the increased use of noninvasive ventilation and less surfactant instillation has impacted the development of bronchopulmonary dysplasia (BPD) using four currently used BPD definitions.Study DesignThis is a retrospective, single‐center cohort study of neonates born at less than 28 weeks gestation between 2010 and 2018. A respiratory practice change (less surfactant and more noninvasive ventilation) occurred in 2014 following participation in the Surfactant Positive Airway Pressure and Pulse Oximetry trial. Therefore, patients were divided into two epochs to compare postnatal respiratory and clinical course and BPD outcomes across four currently relevant definitions (Vermont Oxford Network, National Institute of Child Health and Human Development, Canadian, and Neonatal Research Network).ResultsClinical and demographic variables were similar between epochs. Despite significant differences in maternal and infant characteristics and clinical course, the incidence of BPD was not significantly different between the two epochs regardless of the BPD definition utilized. There was a wide range in the incidence of BPD depending on the definition used.ConclusionsDespite decreased use of surfactant administration and invasive mechanical ventilation between the two epochs, the incidence of BPD did not change and there was wide variation depending on the definition used. A better understanding of the risk factors associated with BPD and a consensus definition is urgently needed to: 1) more accurately compare various studies, 2) help facilitate the conduct of clinical trials, and 3) enhance the development of novel therapeutic interventions to improve outcome.
Event‐triggered stabilization for large‐scale interconnected systems with time delays
Authors: Kang Wen , Liu Chuan‐Xin 
Published: June 2022

AbstractThis article addresses the event‐triggered stabilization for large‐scale interconnected systems in presence of time delays. Two types of event‐triggering mechanisms (static event‐triggering mechanism and dynamic event‐triggering mechanism) are constructed. For each case, event‐triggered predictor‐based controller is designed to compensate time delays by using backstepping method. Via Lyapunov approach, constructive exponential stability conditions are established in the framework of linear matrix inequalities (LMIs). A numerical simulation example is given to demonstrate the effectiveness of the proposed methods.
Distributed fault detection for uncertain Lipschitz nonlinear multi‐agent systems in finite frequency domain
Authors: Liang Dingguo , He Zhichen , Li Rongchang , Yang Ying 
Published: June 2022

AbstractThis article focuses on distributed fault detection for uncertain Lipschitz nonlinear multi‐agent systems (MASs). To handle parameter uncertainties, a finite‐frequency unknown input observer (UIO) is designed to formulate the reference residual system and based on it, a robust UIO corresponding to the fault detection system is designed using an model matching approach. In the UIO constructed for one agent, the unknown input composed of faults in the other agents and disturbances in the whole system is partitioned to decouple part of them, which avoids the constraint of the rank condition of UIO and allows for fault detection for more than one faulty agent. The generated residual is sensitive to the corresponding fault while robust against the nondecoupled unknown input and parameter uncertainties, of which the design conditions are transformed into a set of linear matrix inequalities (LMIs). A numerical simulation is conducted to illustrate the effectiveness of the proposed method.
Mapping the long‐term influence of river discharge on coastal ocean chlorophyll‐a
Authors: Auricht Hannah , Mosley Luke , Lewis Megan , Clarke Ken 
Published: June 2022

AbstractAlthough the potential of river discharge to support ocean productivity and marine ecosystems is known, the specifics of this relationship are poorly understood in many regions of the world. Global estimates of river flow indicate that river discharge is decreasing due to the increasing fragmentation, extraction and regulation of rivers. This likely means that the contribution of river flow to coastal productivity and water quality is changing, potentially leading to fewer and smaller magnitude ocean fertilisation events. We developed a simple analysis method, based on Earth observation data, to investigate where coastal ocean chlorophyll‐a is most strongly influenced by river discharge. The per‐pixel spatiotemporal correlation technique (implemented using Python) correlates chlorophyll‐a concentration (a proxy for phytoplankton biomass and indicator of primary productivity) from MODIS ocean colour data with river discharge data. The method was tested globally on 11 different rivers discharging into coastal ocean regions. Our findings suggest some of the world's largest river systems, such as the Amazon River, have zones of elevated coastal chl‐a that extend hundreds to thousands of km from the river mouth. These findings suggest the influence of river discharge may have been underestimated in many coastal regions of the world. The method appears more effective for larger river systems discharging to ocean waters with less complex nutrient dynamics and weaker seasonal productivity patterns, most notably in temperate regions. Increasing our understanding of the specific areas influenced by river discharge, and the degree of influence over space and time, is an important step towards the improved river and coastal management. This method will increase the capacity of researchers to monitor how, when and where coastal waters are affected as river discharge continues to change into the future.
Kernel learning with nonconvex ramp loss
Authors: Liang Xijun , Zhang Zhipeng , Chen Xingke , Jian Ling 
Published: June 2022

AbstractWe study the kernel learning problems with ramp loss, a nonconvex but noise‐resistant loss function. In this work, we justify the validity of ramp loss under the classical kernel learning framework. In particular, we show that the generalization bound for empirical ramp risk minimizer is similar to that of convex surrogate losses, which implies kernel learning with such loss function is not only noise‐resistant but, more importantly, statistically consistent. For adapting to real‐time data streams, we introduce PA‐ramp, a heuristic online algorithm based on the passive‐aggressive framework, to solve this learning problem. Empirically, with fewer support vectors, this algorithm achieves robust empirical performances on tested noisy scenarios.
Inconsistency between subjective propensity and practice of sustainable consumption: Impact of the consumers' values‐in‐behavior and social participation
Authors: Hwang Hyesun , Yeo Harim 
Published: June 2022

AbstractThis study examined the gap between the consumers' subjective propensity to engage in sustainable consumption and their actual behavior to develop an understanding of the consumers' practical contribution to sustainable development. This study examined the gaps between the consumers' subjective propensity to hold sustainable consumption attitudes or beliefs and their practical behavior by focusing on the value consumers assign to sustainable consumption while engaging in such behavior. Additionally, the effects of the consumers' social relationships and civic participation on sustainable consumption and the propensity‐behavior gap were investigated. Survey data were collected by a professional market research organization from 422 panel consumers. The results indicate that functional value influences actual behavior, while subjective propensity is affected by emotional and altruistic values, as well as by functional value. Bridging social capital negatively affects actual practice of sustainable consumption, whereas the consumers' civic roles have the opposite effect. Finally, the gap between propensity and actual behavior is more likely to occur when consumers are led by emotional and altruistic values of sustainable consumption.
High‐cycle variable amplitude fatigue experiments and design framework for bridge welds with high‐frequency mechanical impact treatment
Authors: Shams‐Hakimi Poja , Al‐Karawi Hassan , Al‐Emrani Mohammad 
Published: June 2022

AbstractFatigue enhancement by way of high‐frequency mechanical impact (HFMI) treatment can enable effective design and construction of steel bridges. However, bridges may experience high and varying mean stresses, the effects of which are not covered today by any design recommendation or in the literature on HFMI‐treated joints. In this study, fatigue experiments were conducted with realistic in‐service bridge loading, which revealed the same high fatigue performance as for constant amplitude loading. The effect of mean stress in spectrum loading was quantified and a method to account for it in an equivalent manner is proposed. A design framework has been developed for design and engineering purposes.
