Wave-equation Traveltime Tomography Unravels a Scenario of Horizontal Mantle Flow Beneath the North China Craton

The North China craton (NCC) was dominated by tectonic extension from late Cretaceous to Cenozoic, yet seismic studies on the relationship between crust extension and lithospheric mantle deformation are scarce. Here we present a three dimensional radially anisotropic model of NCC derived from wave-equation traveltime tomography to address this issue. We find a prominent low S-wave velocity anomaly at lithospheric mantle depths beneath the Taihang Mountains, which extends eastward with a gradually decreasing amplitude. The horizontally elongated low-velocity anomaly is also featured by a distinctive positive radial anisotropy (VSH>VSV). Combining geodetic and other seismic measurements, we speculate the presence of a horizontal mantle flow beneath central and eastern NCC, which led to the extension of the overlying crust. We suggest that the rollback of Western Pacific slab likely played a pivotal role in generating the horizontal mantle flow at lithospheric depth beneath the central and eastern NCC.
The Potential for Restorative Justice Practice for Addressing Intimate Partner Violence with Queer Couples

Abstract Sexual minority individuals (e.g., lesbian, gay, bisexual) are at increased risk to experience intimate partner violence (IPV) compared to heterosexual individuals. When working with these couples it is critical for therapists to provide queer affirming care by recognizing influential social conditions on IPV (i.e., minority stressors). However, many sexual minority individuals who have been harmed by their partners report being unable to access queer affirming care. One largely undiscussed practice is restorative justice in the context of couple therapy. This paper theorizes ways to conduct safe restorative justice practice with queer couples where IPV is present. Based on extant research and established recommendations for queer affirming care, we propose a three-phase approach encompassing training, assessment, and restorative mediation.
Male competition reverses female preference for male chemical cues

Abstract Females must choose among potential mates with different phenotypes in a variety of social contexts. Many male traits are inherent and unchanging, but others are labile to social context. Competition, for example, can cause physiological changes that reflect recent wins and losses that fluctuate throughout time. We may expect females to respond differently to males depending on the outcome of their most recent fight. In Bolitotherus cornutus (forked fungus beetles), males compete for access to females, but copulation requires female cooperation. In this study, we use behavioral trials to determine whether females use chemical cues to differentiate between males and whether the outcome of recent male competition alters female preference. We measured female association time with chemical cues of two size‐matched males both before and after male–male competition. Females in our study preferred to associate with future losers before males interacted, but changed their preference for realized winners following male competitive interactions. Our study provides the first evidence of change in female preference based solely on the outcome of male–male competition.
Youth’s Physical Activity and Fitness from a Rural Environment of an Azores Island

This study aimed to characterize and compare physical activity (PA) and fitness levels by sex in 109 students of a rural environment. The participants were between 15 and 20 years old, from the Santa Maria High School in the Azores’ Santa Maria island. PA levels were assessed by International Physical Activity Questionnaire (IPAQ)-short form. The physical fitness was evaluated by the Fitnessgram battery tests. The sample of this study were physically active, 67.9% were classified with high and moderate PA levels. Regarding the sex comparisons, no significant differences between PA levels were founded. However, males presented higher values of vigorous physical activity, whereas females spent more time in moderate activity, such as walking. Moreover, females had more time in sitting positions during the week and weekend. Regarding the physical fitness levels, males presented significantly higher performances in the upper strength (p < 0.001) and aerobic capacity tests (p < 0.001), whereas females showed higher values in the sit and reach test (p < 0.001), in the trunk lift test (p < 0.005), and in the fat mass values (p < 0.001). It seems reasonable to assume that there is a sociodemographic influence on the PA and physical fitness levels in our sample. We may speculate that rural life provides more opportunities for youth for being physically active than urban life. No differences were founded between sexes for physical activity. However, differences were found between sex for strength, flexibility, cardiorespiratory fitness, and body composition. That might be explained by the biological differences and the type of physical activity habits that each sex use to have in rural environmental.
Joint Message-Passing-Based Bidirectional Channel Estimation and Equalization With Superimposed Training for Underwater Acoustic Communications

Acquiring accurate channel state information and mitigating severe intersymbol interference are challenging for underwater acoustic communications with moving transceivers due to the rapid changes of the underwater acoustic channels. In this work, we address the issue using a superimposed training (ST) scheme with a powerful channel estimation method. Different from the conventional time-multiplexed training, training sequences with a small power are superimposed with symbol sequences. The training signals are transmitted over all time, leading to enhanced tracking capability to deal with time-varying channels at the cost of only a small power loss. To realize this, based on the belief propagation, we develop a message-passing-based bidirectional channel estimation (BCE) algorithm, where all messages are Gaussian, enabling efficient implementation. In particular, the channel correlations are fully exploited through a forward recursion and a backward recursion, thereby achieving accurate channel estimation. Moreover, the ST-based BCE is combined with channel equalization (in the frequency domain) and decoding, and they are performed jointly in an iterative manner to significantly enhance the overall system performance. Field experiments were carried out in Jiaozhou Bay in 2019, and the results verify the effectiveness of the proposed scheme and algorithm.
Three-dimensional Riemannian manifolds and Ricci solitons

Abstract We characterize the three-dimensional Riemannian manifolds endowed with a semi-symmetric metric ρ-connection if its Riemannian metrics are Ricci and gradient Ricci solitons, respectively. It is proved that if a three-dimensional Riemannian manifold equipped with a semi-symmetric metric ρ-connection admits a Ricci soliton, then the manifold possesses the constant sectional curvature −1 and the soliton is expanding with λ = −2. Next, we study the gradient Ricci solitons in such a manifold. Finally, we construct a non-trivial example of a three-dimensional Riemannian manifold endowed with a semi-symmetric metric ρ-connection admitting a Ricci soliton and validate our some results.
Long-non Coding RNAs Related to Fat Deposition in Pigs Included lncRNA Corresponding to Human MALAT1

Obesity is a problem in the last decades since the development of different technologies forced the submission of a faster pace of life, resulting in nutrition style changes. In turn, domestic pigs are an excellent animal model in recognition of adiposity-related processes, corresponding to the size of individual organs, the distribution of body fat in the organism, and similar metabolism. The present study applied the next-generation sequencing method to identify adipose tissue (AT) transcriptomic signals related to increased fat content by identifying differentially expressed genes (DEGs), included long-non coding RNA molecules. The Freiburg RNA tool was applied to recognise predicting hybridisation energy of RNA-RNA interactions. The results indicated several long non-coding RNAs (lncRNAs) whose expression was significantly positively or negatively associated with fat deposition. lncRNAs play an essential role in regulating gene expression by sponging miRNA, binding transcripts, facilitating translation, or coding other smaller RNA regulatory elements. In the pig fat tissue of obese group, increased expression of lncRNAs corresponding to human MALAT1 was observed that previously recognised in the obesity-related context. Moreover, hybridisation energy analyses pinpointed numerous potential interactions between identified differentially expressed lncRNAs, and obesity-related genes and miRNAs expressed in AT.
Fault Diagnosis of Electric Impact Drills Based on Time-Varying Loudness and Logistic Regression

As the main component of an electric impact drill, the gearbox is used to decelerate and transmit power; damage and failure to the gears often lead to the transmission system's failure. Therefore, as the core component of power transmission, the fault detection and diagnosis of gearbox devices have attracted increasing attention. This paper presents a psychoacoustic-based fault diagnosis method for gears of electric impact drills. The proposed methods employ acoustic signals and the time-varying loudness theory of psychoacoustic parameters. Two states of electric impact drills were analyzed: an electric impact drill with healthy gears and an electric impact drill with faulty gears. A feature extraction peak-to-average ratio (PAR) method based on the time-varying loudness spectrum was described and implemented to compute the feature vectors. The classification was carried out by applying logistic regression (LR). This paper provides the results of an acoustic analysis of electric impact drills. The results had a good recognition rate and the total accuracy of recognition of EIDs based on the PAR with LR was 97%. This method simulates the human auditory perception to detect the gear components of an electric impact drill, which can replace the traditional artificial listening detection method.
Blurring luxury: the mediating role of self-gifting in consumer acceptance of phygital shopping experiences

Abstract The question of how to maintain allure and exclusivity while digitizing luxury brands is a pressing issue. A potential solution is to launch new retail formats that allow luxury shoppers to blur physical and digital (phygital) channels through mobile devices. Luxury shoppers, then, can use their newfound “powers” to fantasize and indulge in store atmospheres through mobile-mediated activities. To that end, this article investigates whether self-gifting, a hedonic shopper behaviour, can drive the acceptance of phygital shopping experiences alongside status-seeking and fashion opinion leadership (OL). To test this prospect, the research design employs an industry consultation and an empirical study. In Study 1, design thinking is leveraged to develop and pre-screen realistic interaction intentions on technology executives in the apparel industry (N = 50). This consultation yields nine interaction intentions that enable shoppers to build communities, break the rules, and alter the division of labour within retail stores. Then, Study 2 involves collecting online survey data from a luxury panel (N = 321) to test a structural equation model. The results show that status-seeking and fashion OL are positively associated with interaction intentions towards phygital shopping experiences. Meanwhile, self-gifting is a generative mechanism for interaction intentions, which mediates fashion OL and partially mediates status-seeking. Therefore, hedonic experiences such as self-gifting and the support of fashion influencers are critical to advance luxury shoppers towards accepting phygital shopping experiences. Yet, status-seeking is needed to a lesser but still important degree to maintain exclusivity in luxury stores.
A new bladed assembly simulator and an improved two-parameter plot method for blade tip-timing numerical simulations

The blade tip-timing measurement technique is presently the most promising technique for monitoring the blades of axial turbines and aircraft engines in operating conditions. Due to the high cost of experimental simulations of blade tip-timing–based condition monitoring methods, a numerical simulator for the vibrational behavior of bladed assemblies can be helpful for researchers interested in this field. So far, in most of the numerical simulators, the centrifugal effect of rotational speed on the natural frequencies is neglected. In this study, a new bladed assembly considering the centrifugal effect of the rotational speed for blade tip-timing numerical simulations is proposed. Moreover, an improvement in the engine order estimation algorithm in a two-parameter plot method is accomplished. In the assembly, blades are assumed to be cantilevered Euler–Bernoulli beams coupled together using linear springs. The finite element method is used to extract mass and stiffness matrices from differential equations of the system. By using the two-parameter plot method, the engine order of the excitation is detected. To examine the performance of the algorithm, Monte–Carlo simulation is implemented. The new simulator fulfills both cyclic symmetry and increase in the natural frequencies with increase in rotational speed. Engine order estimation with the new formulation in the two-parameter plot method is accurate. Hence, the new simulator and formulation for two-parameter plot method are reliable for numerical simulations.
Mediating Effects of Family Stress on the Relationship between Self-Efficacy and Midlife Crisis in Middle-Aged Men

Middle-aged men bridge younger and older generations and are burdened with social roles and responsibilities that increase their risk of poor health. The aim of this study was to investigate whether family stress had a mediating effect on the relationship between self-efficacy and midlife crisis in a sample of 198 middle-aged South Korean men. Mediation analysis was performed according to the Baron and Kenny method and using the Sobel test. This study confirmed that midlife crisis decreased with increased self-efficacy and increased with family stress level. Family stress was also a significant partial mediator of the relationship between self-efficacy and midlife crisis. As family stress influences all members of the family, interventions are required that engage all family members to alleviate stress. Strategies to boost self-efficacy should be utilized, and family support constitutes the best means of coping.
A New Reclassification in International Container Transport Market Based on the Impact of “One Belt And One Road” Initiative

Research about the efficiency of the world's major container ports has always being one of the hot issues in container port market. Especially when the “One Belt And One Road” initiative proposed in 2013, the pattern of the world container market is constantly changing. This study aims at examining the changes in world's top 20 international container ports in the new era of the shipping competition market. In current study, we obtained the input data from the Containerization International Yearbook and the journal of commerce annual top world container ports. The concept of ‘self-appraisal’ and ‘peer-appraisal’ is proposed to construct a new reclassification for clustering world's top container ports into three different types. This study exposes that the world's international container market is showing a good development momentum by the impact of the “One Belt And One Road” initiative. However, the situations of inputs surplus or waste resources also exist in some top international container ports. According to characteristics and demands of each port, we put forward some corresponding recommendations with which the operators can adjust their operations and marketing strategies.
D-BERT: Incorporating dependency-based attention into BERT for relation extraction

National Key Research and Development Program of China, Grant/Award Number: 2016YFB1000905; the State Key Program of National Nature Science Foundation of China, Grant/Award Number: 61936001 Abstract Relation extraction between entity pairs is an increasingly critical area in natural language processing. Recently, the pre‐trained bidirectional encoder representation from transformer (BERT) performs excellently on the text classification or sequence labelling tasks. Here, the high‐level syntactic features that consider the dependency between each word and the target entities into the pre‐trained language models are incorporated. Our model also utilizes the intermediate layers of BERT to acquire different levels of semantic information and designs multi‐granularity features for final relation classification. Our model offers a momentous improvement over the published methods for the relation extraction on the widely used data sets.
Estimation of Site Amplification from Geotechnical Array Data Using Neural Networks

We use deep learning to predict surface-to-borehole Fourier amplification functions (AFs) from discretized shear-wave velocity profiles. Specifically, we train a fully connected neural network and a convolutional neural network using mean AFs observed at ∼600 KiK-net vertical array sites. Compared with predictions based on theoretical SH 1D amplifications, the neural network (NN) results in up to 50% reduction of the mean squared log error between predictions and observations at sites not used for training. In the future, NNs may lead to a purely data-driven prediction of site response that is independent of proxies or simplifying assumptions.
Molecular Surveillance and Burden of Plasmodium falciparum Isolate to the Resistance of Artemisinin and Mefloquine-based Therapy among Febrile Subjects in Ilorin Metropolis, North-Central Nigeria

Introduction: Artemisinin-based combination treatments (ACTs) such as Artemisinin and mefloquine are generally accepted as the best forms of therapy for uncomplicated falciparum malaria and usually exceed more than 90% effectiveness. However, the problem of resistance to Original Research Article Nassar et al.; JAMB, 21(3): 27-35, 2021; Article no.JAMB. 65575 28 the target parasites remains a great challenge especially within the northcentral Nigeria. Therefore this study aimed to assess the burden of resistance of Plasmodium falciparum to artemisinin and Mefloquine from the blood smear febrile patients attending tertiary health facility in Ilorin, Nigeria. Methodology: The study was carried among two hundred and one (201) consented febrile individuals age ranged 1-46 years (Mean=22.7 years; M=39; F=61) between May and August 2019. Blood samples collected were subjected to Microscopy using Giemsa staining technique and Rapid diagnostic test (RDT) using (SD BIOLINE Malaria Ag P.f/Pv, South Korea) kit to detect the presence of P. falciparum A semi-structured questionnaire was used to capture demographic and other relevant information while data was analysed with SPSS version 21. Results: Of the 201 samples tested, 113 (56.5%) were positive for Microscopy and RDT. Fifty of the positive samples for Microscopy and RDT were further subjected to PCR technique for the presence of Plasmodium falciparum and amplification of Kelch13 and FR1gene mutation of which one (2.0%) showed amplification for the PfKelch13 gene mutation for artemisinin while none was recorded for FR1 gene mutation in case of Mefloquine. Conclusion: This study reported a high rate of detection for Plasmodium falciparum using microscopy and RDT but moderately low rate of resistance to amplification for the PfKelch13 gene mutation for artemisinin but none for FR1 gene mutation for mefloquine by PCR. This suggests a clue for further monitoring of the artemisinin and Mefloquine resistance by detection of some molecular markers in k13 and FRI genes of Plasmodium in our communities in Nigeria.
Analysis of Spatial Variability of River Bottom Sediment Pollution with Heavy Metals and Assessment of Potential Ecological Hazard for the Warta River, Poland

Pollution of river bottom sediments with heavy metals (HMs) has emerged as a main environmental issue related to intensive anthropopressure on the water environment. In this context, the risk of harmful effects of the HMs presence in the bottom sediments of the Warta River, the third longest river in Poland, has been assessed. The concentrations of Cr, Ni, Cu, Zn, Cd, and Pb in the river bottom sediments collected at 24 sample collection stations along the whole river length have been measured and analyzed. Moreover, in the GIS environment, a method predicting variation of HMs concentrations along the whole river length, not at particular sites, has been proposed. Analysis of the Warta River bottom sediment pollution with heavy metals in terms of the indices: the Geoaccumulation Index (Igeo), Enrichment Factor (EF), Pollution Load Index (PLI), and Metal Pollution Index (MPI), has proved that, in 2016, the pollution was heavier than in 2017. Assessment of the potential toxic effects of HMs accumulated in bottom sediments, made on the basis of Threshold Effect Concentration (TEC), Midpoint Effect Concentration (MEC), and Probable Effect Concentration (PEC) values, and the Toxic Risk Index (TRI), has shown that the ecological hazard in 2017 was much lower. Cluster analysis revealed two main groups of sample collection stations at which bottom sediments showed similar chemical properties. Changes in classification of particular sample collection stations into the two groups analyzed over a period of two subsequent years indicated that the main impact on the concentrations of HMs could have their point sources in urbanized areas and river fluvial process.
The effects of rubrics on evaluative judgement: a randomised controlled experiment

Abstract Rubrics have been suggested as a means to foster students’ evaluative judgement, the capacity to appraise their own work and that of others; however, empirical evidence of rubrics’ effectiveness is still emerging. This paper contributes findings from a randomised controlled experiment on the effect of rubrics on evaluative judgement. Participants were randomly assigned to one of two groups: a control group which evaluated peer-authored learning resources without the use of a rubric and an experiment group which carried out the evaluation using a three-item rubric based on (1) alignment with course content, (2) accuracy and (3) clarity. Both groups were asked to rate their confidence and provide comments to justify their scoring. The results showed a small effect size in increasing average agreement on the quality of learning resources in the experiment group. Analysis of comments reveals that criteria in and beyond the rubric guided participants’ ratings of quality. The study provides evidence of the impact of rubrics on students’ evaluative judgement and an example of how data-driven approaches and learning analytics can inform actionable design choices for embedding pedagogically supported strategies derived from the literature into actively operating educational technologies.
