Sequencing and characterization of mitochondrial genome of Idaea effusaria (Lepidoptera: Geometridae)

Abstract The Idaea effusaria belongs to Geometridae in Lepidoptera. The complete mitogenome of I. effusaria was described in this study, which is typically circular duplex molecules and 16,161 bp in length, containing the standard metazoan set of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and an A + T-rich region. The gene order is same with other lepidopterans. Except for cox1 started with CGA, all other PCGs started with the standard ATN codons. Most of the PCGs terminated with the stop codon TAA, whereas cox2 has the stop codon CAT. The phylogenetic tree showed that Larentiinae is close to Sterrhinae. The species of Ennominae form a monophyly.
An Automated Workflow for Real-Time Monitoring and Benchmarking of Connection Time in Drilling Operations

Invisible lost time (ILT) during drilling can add up to be extremely costly. Since a significant portion of ILT occurs during drilling and tripping operations (including running casing), the aim is to develop a workflow based on analytics algorithms that accurately identify and record how long it takes to make both drilling and tripping connections in real time using 1-second surface data. By capturing these KPIs, performance differences across the rig fleet were identified, and best practices were shared. The developed workflow and algorithms for the drilling and tripping connection times can be applied to both active and historical wells in a fully automated fashion. The algorithm consumes 1-second surface drilling data to identify each connection. For more in-depth analysis, the drilling connection is divided into three stages: pre-connection, slip-to-slip, and post-connection. The algorithm relies on an advanced "rig state" (e.g., drilling, tripping in, tripping out, running casing) to determine the current state of the drilling process. The algorithm was applied to more than 500 historical wells, drilled in three major business units in northwest Texas and southeast New Mexico. These wells had different levels of complexity, from shallow vertical wells to complex horizontal wells, and thus provided a very valuable data set for benchmarking and lookback studies. Through this process, more than 750,000 connections were identified. Analysis was done to determine a correlation between the connection performance and various factors such as rig type and contractor, crew, well design, hole depth, and drilling region. Best performers were identified for each unit to help determine the operational goals. The analysis showed that the drilling connection time varied significantly among different rigs, with a gap of more than 3 minutes for one of the business units, suggesting a huge improvement opportunity. In addition, the algorithm is currently being deployed at the rig site using the Internet of Things (IoT) Edge technology to run the application locally in real time and provide the drill site manager and driller with connection time, which had immediate impact on performance improvement. The developed workflow in association with the algorithm, online visualization platform, and real-time monitoring, provides a powerful tool to improve efficiency, set realistic goals, make intelligent business decisions, and reduce the well delivery time without compromising safety. In addition, this study reveals that a reduction of up to 3% in drilling time of future wells can be achieved by lowering the current average connection time to the P10 value (best performers).
The Structure, Morphology, and Mechanical Properties of Ta-Hf-C Coatings Deposited by Pulsed Direct Current Reactive Magnetron Sputtering

Ta, Hf, TaCx, HfCx, and TaxHf1-xCy coatings were deposited by reactive pulsed Direct Current (DC) magnetron sputtering of Ta or Hf pure metallic targets in Ar plus CH4 gas mixtures. The properties have been investigated as a function of the carbon content, which is tuned via the CH4 flow rate. The discharge was characterized by means of Optical Emission Spectroscopy and, in our conditions, both Ta-C and Hf-C systems seem to be weakly reactive. The structure of the as-deposited pure tantalum film is metastable tetragonal β-Ta. The fcc-MeCx carbide phases (Me = Ta or Hf) are {111} textured at low carbon concentrations and then lose their preferred orientation for higher carbon concentrations. Transmission Electron Microscopy (TEM) analysis has highlighted the presence of an amorphous phase at higher carbon concentrations. When the carbon content increases, the coating’s morphology is first compact-columnar and becomes glassy because of the nano-sized grains and then returns to an open columnar morphology for the higher carbon concentrations. The hardness and Young’s modulus of TaCx coatings reach 36 and 405 GPa, respectively. For HfCx coatings, these values are 29 and 318 GPa. The MeCx coating residual stresses increase with the addition of carbon (from one-hundredth of 1 MPa to 1.5 GPa approximately). Nevertheless, the columnar morphology at a high carbon content allows the residual stresses to decrease. Concerning TaxHf1-xCy coatings, the structure and the microstructure analyses have revealed the creation of a nanostructured coating, with the formation of an fcc superlattice. The hardness is relatively constant independently of the chemical composition (22 GPa). The residual stress was strongly reduced compared to that of binary carbides coatings, due to the rotation of substrates.
Low-Cost Carriers versus High-Speed Rail: Understanding Key Drivers of Passengers' Choice in China

Abstract:This study investigated passengers' choice between high-speed rail (HSR) and low-cost carriers (LCCs) in China. A survey of 1,080 passengers was performed and a logit regression method was used to identify the key factors in modal choice behaviors. The results indicated that frequency, price, perceived behavioral control (PBC), and attitudes were significant determinants of choice between HSR and LCCs, while service quality, access, and subjective norms were not important factors. Group differences in terms of the factor impact were also identified. Frequency and attitudes had a greater influence on business passengers, compared to nonbusiness passengers, in terms of their mode preference. Price affected the two types of passenger groups in a similar way, while PBC only influenced the choice behavior of the nonbusiness passengers. These findings fill the knowledge gap of the choice between HSR and LCCs and provide useful insights for HSR and LCCs to improve competitiveness in China.

Ikedosoma (Annelida: Echiura: Thalassematidae) from the Tropical Pacific, with Description of a New Species

A new species of the thalassematid echiuran Ikedosoma abemama sp. nov. is described based on a single specimen collected from Abemama Atoll, the Gilbert Islands, Kiribati. The species is particularly distinguishable from all congeners by the absence of the proboscis lower lip. A single specimen of Ikedosoma collected from Dam Bay, Nha Trang, Vietnam is also described, being similar to the new species, although its poor condition prevented a positive identification. The first confirmed records of Ikedosoma from the tropical Pacific Ocean are included (hitherto known only from temperate waters of Japan), in addition to a summary table of diagnostic characteristics and a dichotomous key to the species of Ikedosoma .
Differentiation of Self and Hope Mediated by Resilience: Gender Differences

The intent of the present study was to examine the associations among differentiation of self, resilience and hope. Extending Bowen’s family systems theory to adolescents in a middle eastern culture, we anticipated age and gender-based differences in the level of the constructs as well as in the associations among them. Employing a multistage cluster sampling procedure, a sample of 300 adolescents (132 girls and 168 boys) ranging in age from 14 to 19 years old (M = 16.36 years; SD = 1.24) were recruited from junior and senior high schools in Khoramabad. Data were collected through self-report measures, Differentiation of Self Inventory, Connor-Davidson Resilience Scale and Snyder Hope Scale, and analyzed via descriptive statistics, correlations and bootstrap analyses. Higher scores of differentiation were related to greater resilience and hope. Scores on I-position, emotional cutoff and fusion with others were also associated with resilience and hope. Age and gender differences emerged in certain components of differentiation. However, a moderated mediation analysis revealed no moderating effects of age and gender in the association between differentiation and resilience. Separate gender based bootstrapping results for mediation highlighted the specific indirect paths that resilience has in the relationship between I-position and hope in adolescent boys and between emotional closeness (low emotional cutoff) and hope in adolescent girls. Findings are discussed with regard to the cross-cultural validity of Bowen family systems theory.

Frequency-Division Virtual Impedance Shaping Control Method for Grid-Connected Inverters in a Weak and Distorted Grid

Grid-connected current quality is seriously affected by the low-order background harmonics in the gird-inverter dynamic system. The point of common coupling voltage feedforward impedance reshaping method of the grid-connected inverter is generally applied to solve this problem, however about 90° phase lag of the inverter output impedance is brought in, which would deteriorate the adaptability of the inverter to the weak grid. To solve this problem, this article proposes a novel frequency-division virtual impedance shaping method, which shapes the output impedance of the grid-connected inverter with different coefficients in different frequency bands, respectively. The basic principles, parameters design, and application analysis are studied in detail. With the proposed scheme, the grid-connected inverter can be equipped with strong adaptability to a wide range of grid impedance and suppression ability to the background voltage harmonics simultaneously. Theoretical analysis and experimental results confirm the effectiveness of the proposed method.
From Developmental Education to Transfer and Bachelor’s Degree Attainment: A Study of Community College Students’ Long-Term Outcomes

FROM DEVELOPMENTAL EDUCATION TO TRANSFER AND BACHELOR’S DEGREE ATTAINMENT: A STUDY OF COMMUNITY COLLEGE STUDENTS’ LONG-TERM OUTCOMES Kathryn Mahaffey Harvey Old Dominion University, 2019 Director: Dr. Shana L. Pribesh Community college is the only pathway to higher education for many students. Jenkins and Fink (2016) reported that 40% of new college students entered higher education through a community college. Most of these students aspire to earn a bachelor’s degree (Fink 2014). In order to achieve their dream of bachelor’s degree attainment, many of these students need to first complete a series of developmental or remedial courses to become college-ready and begin taking curriculum courses. The purpose of this study was to analyze the relationship between developmental education course completion and transfer success by comparing the longitudinal outcomes of students who took developmental courses at a community college with those who did not take developmental courses. The three outcomes analyzed were: 1) transfer to a fouryear institution, 2) bachelor’s degree attainment, and 3) transfer to a for-profit institution. In addition to comparing the long-term transfer outcomes of developmental education students versus non-developmental education students, the study also compared two research approaches. One analysis was conducted using a non-matched sample and the other was conducted using a propensity score matched sample. The differences between the results of the two designs was of particular interest. The non-matched sample, for the most part, yielded the typically expected results. However, the more rigorous, matched-sample design indicated that the number of credit hours earned at the community college is the only significant predictor of
An Empirical Examination of Shift‐Share Instruments

Bartik's (1991, 1993) approach to identifying shocks in demand to regional economies has been used extensively for nearly thirty years. We chronicle the development of Bartik-type shift-share instruments and examine the empirical performance of alternative versions that use different combinations of national shift and local share variables in their construction. We offer three main findings. First, instruments constructed from shares that omit employment in non-traded sectors empirically dominate versions that include total employment. Second, industrial sectors with high average shares and low variation across areas are more likely to be non-traded and endogenous. This suggests placing large weights on non-traded sector shares worsens both relevance and potential endogeneity. Finally, we demonstrate national shifters other than employment, such as prices and wages, can be used to construct instruments with unique and relevant explanatory power.
Shopping Streets and Neighborhood Identity: Retail Theming as Symbolic Ownership in New York

As the economies of production and trade have dwindled in Western cities, urban locales have had to capitalize on other opportunities for growth. Middle and upper class consumers are now sought after resources for cities and neighborhoods once supported by manufacturing. This article considers the role of local retail actors in shifting neighborhood identity towards luxury consumption. Important in this transformation is the process of theming by which business owners rely on cues from the neighborhood's identity and institutions, incorporate these cues into decisions for their own businesses, and thereby reify or change neighborhood identity. By tracing changes on shopping streets in Williamsburg, Brooklyn and Manhattan's Lower East Side, I show how retail theming interacts with neighborhood identity. Interviews with storeowners and archival retail data illuminate how choices made by entrepreneurs or coporations contribute to dramatic aesthetic changes on the street. As the neighborhood identities change, existing long–term residents and less wealthy visitors become excluded from the local shopping streets and lose ownership over neighborhoods.
Real-time sitting behavior tracking and analysis for rectification of sitting habits by strain sensor-based flexible data bands

From human–machine interfaces to human–computer/robot interaction, the prevailing pattern has gradually become one of people remaining in a sitting posture while working. However, unhealthy sitting behavior seriously affects human health. This paper presents a novel tracking and analysis method of real-time sitting behavior. It is designed using a series of flexible wearable data bands, based on flexible stretchable sensors and pressure sensors (PSNRs). A flexible PSNR is fabricated using composites of carbon black, carbon nanotubes and silicon rubber, by a mixed solution method; it possesses a good property of pressure perception, for tracking sitting behavior. The sensors are accurately attached to human joints for accurate measurement of joint movement at the shoulders, elbows, wrists, knees, and waist. In this work, a new idea of real-time sitting behavior recognition is introduced and developed, based on a radial basis function neural network. Dynamic time warping is used to select candidates for dynamic sitting behavior and also to recognize postures by comparing the observed records with a series of pre-recorded reference data patterns. The solution deals simultaneously with real-time sitting behaviors as well as with multiple joints within the area of interest, to monitor the health level of the sitting behavior and to remind humans of sitting habits. The experimental results of the real-time sitting behavior tracking and analysis verify the effectiveness of the proposed methods. Additionally, undesirable sitting behaviors were gradually rectified and the sitting habit health levels of the participants were gradually increased.
Nutritional values and chemical composition of tropical pastures as potential sources of α-tocopherol and condensed tannin

Tropical pastures can be important natural sources of antioxidant compounds and may impact production and quality of animal protein with repercussions on human health. The objective of this study was to evaluate the concentrations of α-tocopherol, condensed tannin (CT) and nutritional values of important tropical species used in grazing. The species included guinea grass (Panicum maximum), bermudagrass (Cynodon spp.), pigeon pea (Cajanus cajan), soybean (Glycine max), creeping beggarweed (Desmodium incanum), macrocephala stylo (Stylosanthes macrocephala) and pinto rhizoma peanut (Arachis pintoii). The species were distributed in a randomised block design with four replicates each. There were no differences in α-tocopherol between the mid and late growing season; there were likewise no differences among forage species. The highest (P = 0.02) concentrations of CT were observed in creeping beggarweed (66.5 ± 13.8 g kg−1 dry matter [DM]), pinto (15.7 ± 5.2 g kg−1 DM) and pigeon pea (8.7 ± 0.8 g kg−1 DM). Among these species, creeping beggarweed showed the highest percentage of extractable CTs (68% of total CT) and was the only species where the CT showed biological activity (protein precipitation by phenols = 60.1 g kg−1 DM). Among the tropical grasses and legumes, creeping beggarweed could become an important CT source for animal production.
Magnetoelectric Coupling in Epitaxial Multiferroic BiFeO3–BaTiO3 Composite Thin Films

Herein, the magnetoelectric (ME) performance of epitaxial multilayer composite films built from nanometer‐thick layers of multiferroic BiFeO3 and ferroelectric BaTiO3 is reviewed. A successful implementation of shadow‐mask pulsed laser deposition considerably reduces the interface and surface roughness of the multilayers. In dependence of double‐layer thickness and the degree of structural perfection, the multilayers show high ME voltage coefficients up to 480 V cm−1 Oe−1 at 300 K and 0 T bias magnetic field. With decreasing double‐layer thickness, an interface‐driven effect critically enhances the ME coupling in this strain and charge–comediated system. Interestingly, the characteristics of temperature and DC magnetic field dependencies of magnetoelectric voltage coefficients change with the transition from the 2D to 3D character of the single layers, i.e., for BiFeO3 layers thicker than 5 nm within the multilayers. These changes are attributed to variations of the contributing ME coupling mechanisms. Furthermore, scanning transmission electron microscopy (STEM) with energy‐dispersive X‐ray (EDX) spectroscopy mapping‐based nanoanalysis indicates that chemical effects at the interfaces play an important role for the ME performance of the BiFeO3–BaTiO3 multilayer thin films.
A Novel MAC Protocol for Low Datarate Cooperative Mobile Robot Teams

Cooperative mobile robot applications enable robots to perform tasks that are more complex than those that each single robot can perform alone. In this application context, communication networks play a very important role, as they have to cope with strict requirements (e.g., in terms of mobility, reliability, and bounded latencies). Recent cooperative robot applications foresee the support of low datarate communication technologies, that provide, among other benefits, lower energy consumption and easy integration with Wireless Sensor Networks (WSNs). Unfortunately, the state-of-the-art solutions either entail high costs and complexity or are not suitable for low data rate communications. Consequently, novel solutions for cooperating robots are required. For this reason, this paper presents RoboMAC, a new MAC protocol for mobile cooperating robots that enables the integration of robots with WSNs, supports mobility and real-time communications, and provides high scalability. The paper also presents a proof-of-concept implementation that proves the feasibility of the RoboMAC protocol on COTS devices.
Care worker perspectives on the socio-emotional adjustment of orphans in residential homes

ABSTRACT Orphans in Sub-Saharan Africa are often raised by relatives. Many end up in residential homes due to financial burdens on extended families. As a result, the socio-emotional development of orphans may be adversely affected. This paper explores care workers’ perspectives on the socio-emotional adjustment of orphans in residential homes. Qualitative methods were employed in which eleven male and female care workers from three residential homes for orphans were interviewed. The data was analysed using Thematic Analysis.Results suggest that non-care related duties in the home interfere with care workers’ responsivity to children. Relationships between care workers and children were positive; based on emotional support, listening, responsiveness, and trust. However, orphans tended to have difficulties adjusting to the residential home, expressing emotions, and making friends. Results also showed that orphans continue to deal with the loss of their parents and may, as a result, act in aggressive ways. Recommendations include improved access to psychosocial support and easing care workers’ workload to enable them to effectively aid orphans in navigating their socio-emotional challenges. The paper illustrates key insights into the socio-emotional adjustment of orphans from the perspectives of care workers caring for them.
Effects of crystal orientation and temperature on the deformation mechanism and mechanical property of Cu nanowire

The effects of crystallographic direction and temperature on the deformation mechanism and properties of Cu nanowire (NW) are studied via systematic simulations and theoretical analysis. It is found that the elastic module, yield stress and yield strain are quite different for five oriented NWs. As the crystallographic orientation of NW varies, both the yield stress and the yield strain firstly reduce to the minimum value, then gradually increase. Furthermore, the evolutions of flow stress after yield point are also obviously different for five oriented NWs, which are associated with the plastic deformation mechanisms. With the crystallographic orientation of NW varying, the simulated atomic snapshots show that the dominant deformation mechanism transforms from the shuffling-assisted single dislocation-nucleation to the collective dislocation-nucleation, then to the twinning migration, and finally to the combination of dislocation glide and micro-twinning. According to the normal stress perpendicular to the slip plane and shear stress on the slip plane, the authors theoretically predict the deformation mechanisms for different oriented NWs, which turn to be in good consistent with the authors’ observed deformation mechanisms. Besides, they also propose that the temperature effects are different for different oriented NWs.
