Abstract
Conserving Yellowstone Cutthroat Trout Oncorhynchus clarkii bouvieri by suppressing invasive Lake Trout Salvelinus namaycush in Yellowstone Lake is a high priority for Yellowstone National Park resource managers. Here, we tested whether targeting telemetered Lake Trout could increase the efficacy of Lake Trout suppression by gill netting. Mobile acoustic tracking surveys were performed to identify aggregations of tagged Lake Trout in summer (June–August) 2017. Lake Trout aggregations were relayed daily to suppression crews by phone, radio, or text and a printed map. Suppression crews set 30 large-mesh gill nets targeting telemetered Lake Trout aggregations (target treatment) and 124 large-mesh gill nets not targeting telemetered aggregations (nontarget treatment). Mean loge(CPUE) was higher for the target treatment (0.37; 95% credible interval [CRI] = 0.08–0.65) than for the nontarget treatment (−0.37; 95% CRI = −0.51 to −0.21). Mean of the target treatment was higher than the mean of the nontarget treatment for over 99% of the 1,000 draws from the joint posterior distribution. Because of telemetry costs, mean CPUE per US$10,000 spent was similar between the target treatment (0.20; 95% CRI = 0.15–0.26) and the nontarget treatment (0.15; 95% CRI = 0.13–0.17). Telemetry is an effective strategy for improving Lake Trout CPUE, which corresponds to an increased efficiency in the Lake Trout suppression program.

Published: January 2020

AbstractModelling of emerging vector borne diseases serves as an important complement to clinical studies of modern zoonoses. This article presents an archaeo‐historic epidemiological modelling study of Rift Valley fever (RVF), using data‐driven neural network technology. RVF affects both human and animal populations, can rapidly decimate herds causing catastrophic economic hardship, and is identified as a Category A biodefense pathogen by the US Center for Disease Control. Despite recent origins circa the early 1900s, little is known about the circumstances of its inception nor the relationships between factors that affect transmission. This evidence could be vital as the disease continues to expand from its epicentre in Kenya to other parts of Africa and the Arabian Peninsula. RVF is a relevant case for archaeological/palaeopathological investigations of disease as it intersects between numerous human, animal, spatial, temporal, and sociopolitical dimensions. By integrating landscape archaeology, historical evidence, and climatic data, with evidence of human behaviour gathered through ethnoarchaeological study, this article presents an applied framework for human–animal palaeopathology. This framework aligns with the One Health approach that observes disease to be intrinsically tied to ecological and societal factors. We provide a useable alternative way of thinking about disease modelling in the present and the past, ultimately seeking to support efforts to accurately predict future impacts. Tapping into longitudinal evidence from the last 50–300 years offers a powerful way to respond to the threat zoonoses will pose to human populations around the world as the climate warms.
The effect of functional zirconium phosphate on aging resistance of nitrile butadiene rubber composites
Authors: Li Tianxiang , Chen Songbo , Wan Songhan , Cai Shuwei , He Xianru 
Published: January 2020

Abstractα‐Zirconium phosphate (α‐ZrP) is intercalated by 4‐aminodiphenylamine (RT) through cation exchange, and its product is named ZrP‐RT. The structure and morphology is characterized by FTIR, XRD, and SEM. RT intercalates into the α‐ZrP layer and RT has monolayer and bilayer permutations in the layer. ZrP‐RT is incorporated into nitrile butadiene rubber (NBR) through mechanical blending, namely, NBR/ZT composites. The compatibility of ZrP‐RT and NBR is investigated by the contact angle test with water of ZrP‐RT, the fracture surface, and XRD of NBR/ZT composites. The introduction of RT significantly increases the dispersion of α‐ZrP in NBR. The aging resistance properties of NBR/ZT composites are tested by mechanical test. The antiaging effect of ZrP‐RT is better than commercial antioxidant. The aging mechanism of NBR/ZT is explored by DMA, equilibrium swelling test, and ATR‐FTIR. It indicates that ZrP‐RT can effectively inhibit the chain crosslink of NBR.

Published: January 2020

AbstractThe 3‐aminopropyltriethoxysilane (APS) grafted aramid fibers were prepared by γ‐ray irradiation and chemical treatment to improve the interfacial properties between aramid fibers and epoxy matrix. The functionalization process of aramid fibers was investigated by scanning electron microscopy, X‐ray photoelectron spectroscopy, and Fourier transform infrared spectrum. After grafted with APS, the surface roughness of aramid fibers increased obviously, and the element content and composition of functional groups changed significantly in the modification process. Dynamic contact analysis indicated the wettability, and surface free energy of the fibers were greatly improved after the APS treatment. Monofilament pull‐out measurement showed that the interfacial shear strength of aramid fiber reinforced composite increased by 51.03%, from 36.33 to 54.87 MPa after the surface modification. Moreover, benefited from the appropriate radiation and the APS grafting, the functionalization process did not damage fiber tensile strength.

AbstractNovel nitrogen‐rich compound featured bicyclic quinoxaline as a basic core structure has been synthesized, 1‐{[1‐(3‐azido‐2‐hydroxypropyl)‐1H‐1,2,3‐triazol‐4‐yl]methyl}‐3‐methyl‐1,2‐dihydroquinoxalin‐2‐one with formula C15H16N8O2, and their structural and chemical reactivity aspects have been comprehensively discussed. Nature, role, and relative contribution of weak noncovalent interactions in supramolecular assembly have been assessed through single‐crystal analysis and computational approaches. Useful information about the global and local reactivity were obtained from Conceptual Density Functional Theory at wB97X‐D/cc‐pVDZ level. Studied system could act as strong electrophile and/or moderate nucleophile in polar organic reactions. We hope this study will provide deeper insight in the knowledge of the synthesis and chemistry of the quinoxaline and quinoxaline derivatives.

Published: January 2020

AbstractMultilayer onion‐like vesicles are valuable in cell mimics and biomedicine fields. However, as an excellent self‐assembly precursor, the formation of multilayer onion‐like vesicles by the self‐assembly of hyperbranched multiarm copolymers (HMCs) were not reported due to the complex self‐assembly dynamics. In this article, the self‐assembly behavior of multilayer onion‐like vesicles from HMCs was systematically investigated using dissipative particle dynamics simulation. The formation conditions for different kinds of vesicles were disclosed through the construction of the morphological phase diagram. Moreover, the formation mechanisms of the onion‐like vesicles with different layers were revealed. We observed that it is the fusion mechanism in low concentrations and the molecular rearrangement mechanism in high concentrations. For low concentration, the law between the number of the membrane layers and the morphology of the aggregates in the fusion process was disclosed. Meanwhile, the membrane of the onion‐like vesicles self‐assembled from HMCs is monolayer structure and the thickness of each layer is decreased in sequence from inside to outside. The current observations have important guiding significance for its application in drug delivery systems.

Published: January 2020

AbstractThe HECT‐type ubiquitin ligase E6AP (UBE3A) is critically involved in several neurodevelopmental disorders and human papilloma virus‐induced cervical tumorigenesis; the structural mechanisms underlying the activity of this crucial ligase, however, are incompletely understood. Here, we report a crystal structure of the C‐terminal lobe (“C‐lobe”) of the catalytic domain of E6AP that reveals two molecules in a domain‐swapped, dimeric arrangement. Interestingly, the molecular hinge that enables this structural reorganization with respect to the monomeric fold coincides with the active‐site region. While such dimerization is unlikely to occur in the context of full‐length E6AP, we noticed a similar domain swap in a crystal structure of the isolated C‐lobe of another HECT‐type ubiquitin ligase, HERC6. This may point to conformational strain in the active‐site region of HECT‐type ligases with possible implications for catalysis.Significance StatementThe HECT‐type ubiquitin ligase E6AP has key roles in human papilloma virus‐induced cervical tumorigenesis and certain neurodevelopmental disorders. Here, we present a crystal structure of the C‐terminal, catalytic lobe of E6AP, providing basic insight into the conformational properties of this functionally critical region of HECT‐type ligases.

AbstractWe report docking performance on the six targets of Critical Assessment of PRedicted Interactions (CAPRI) rounds 39‐45 that involved heteromeric protein‐protein interactions and had the solved structures released since the rounds were held. Our general strategy involved protein‐protein docking using ZDOCK, reranking using IRAD, and structural refinement using Rosetta. In addition, we made extensive use of experimental data to guide our docking runs. All the experimental information at the amino‐acid level proved correct. However, for two targets, we also used protein‐complex structures as templates for modeling interfaces. These resulted in incorrect predictions, presumably due to the low sequence identity between the targets and templates. Albeit a small number of targets, the performance described here compared somewhat less favorably with our previous CAPRI reports, which may be due to the CAPRI targets being increasingly challenging.
Be prepared for the unexpected: The gap between (im)mobility intentions and subsequent behaviour of recent higher education graduates

Published: January 2020

AbstractResearch on the relationship between mobility intentions and actual mobility behaviour is scarce. This study analyses the factors explaining the gap between (im)mobility intentions and behaviour of recent higher education graduates in the Euregio Meuse‐Rhine, a cross‐border region spanning the Netherlands, Belgium, and Germany. The analysis is based on mixed methods, including survey data collected in 2015 and 2017 as well as semistructured interviews to find out more about respondents' personal mobility trajectories and the extent to which their behaviour reflects their actual (im)mobility preferences. The findings indicate that location‐specific capital impacts the probability to realise one's (im)mobility intention, as do other forms of capital, such as previous mobility experience and an internship during the study. Furthermore, personality traits and unexpected events, such as a change in relationship status, influence if respondents realise their initial (im)mobility intention.
Are refugees more likely to leave initial destinations than economic immigrants? Recent evidence from Canadian longitudinal administrative data
Authors: Kaida Lisa , Hou Feng , Stick Max 
Published: January 2020

AbstractSecondary migration is of policy interest in many immigrant‐receiving countries when efforts are made to steer immigrants away from major urban centres. One example is refugee dispersal policy. Although previous research, mostly evaluating the policy itself, argues it would disproportionately increase the secondary migration of refugees settled in nongateway cities, quantitative analysis is limited. This study compares the long‐term secondary migration in Canada by immigrant admission category with a focus on the city size of initial settlement. Our analysis of the Longitudinal Immigration Database finds that although resettled refugees have a higher overall secondary migration rate than economic immigrants, their difference in the likelihood of leaving a same‐size initial destination city is minor. The majority stay in the initial city of residence regardless of admission category. The findings have a strong policy implication; the geographic distribution of immigrants can be influenced most effectively at arrival.
Importance measure method for error sources of degradation systems based on the present worth of expected Taguchi quality loss
Authors: Sun Zhongchao , Yu Tianxiang , Cui Weimin , Song Bifeng 
Published: January 2020

AbstractDeteriorating of the error sources and the deviation of the quality characteristic (QC) of the product from the target value are ubiquitous in practice. Studying the relative contribution of the error sources to the QC deviation is helpful for improving the product performance effectively. In this study, we propose an error importance measure (EIM) method to quantify the relative contribution of error sources to the Taguchi quality loss that is caused by the QC deviation. The present worth of the expected Taguchi quality loss (ETQL) is used to characterize the deteriorating QC deviation. We use Taylor series expansion to decompose the time‐dependent ETQL and the present worth of ETQL into a series of fractions, representing the individual and the interaction contributions of the error sources. Based on the decomposition, the time‐dependent and the time‐independent EIM indices for one and a group of error sources are defined, respectively. The evaluation procedure for the EIM indices is provided and the properties are discussed. Finally, we provide a realistic application case to an aircraft wheel door mechanism to demonstrate the effectiveness of the proposed EIM method.
On a class of mixed EWMA‐CUSUM median control charts for process monitoring

Published: January 2020

AbstractMonitoring of any manufacturing, production, or industrial process can be controlled and improved by removing these special cause of variations using control charts. Shewhart‐type control charts are effective to control a large amount of special variations, whereas, cumulative sum (CUSUM) and exponentially weighted moving average (EWMA) charts detect small and moderate variations efficiently in the process parameters. Monitoring of location parameter can be done with mean control charts under the assumption that the parameters are known or correctly estimated from in‐control samples and data are free from outliers (but in practice data occasionally have outliers). In this study, we have proposed generalized mixed EWMA‐CUSUM median control charts structures for known and unknown parameters based on auxiliary variables for detecting shifts in process location parameter. The proposed charts are compared with the corresponding charts for the mean, based on contaminated and uncontaminated data. Different performance measures are used to evaluate the performance of proposed control charts and revealed through results that the median‐based charts are more sensitive to detect a shift in process location parameter in the presence of outliers. An illustrative example using real data is also shown for practical consideration.

Published: January 2020

AbstractThe future of quantum photonic technology depends on the realization of efficient sources of single photons, the ideal carriers of quantum information. Parametric downconversion (PDC) is a promising route to create highly coherent, spectrally pure single photons for quantum photonics using versatile group velocity matching (GVM) and tailored nonlinearities. However, the functionality to actively control the poling period of nonlinear crystals used in PDC is currently missing, yet would enable to dynamically modify the wavelength of single photons produced in the PDC process. Herein, a detailed GVM study is presented for functional PMN‐0.38PT material which can be dynamically repolled at ambient conditions with fields as low as 0.4 kV mm−1. The study reveals phase‐matching conditions for spectrally pure single photon creation at 5–6 µm. Further, a practical approach is proposed for on‐flight wavelength switching of the created single photons. The reported reconfigurable functionality benefits a wide range of emerging quantum‐enhanced applications in the mid‐IR spectral region where the choice of single photon sources is currently limited.

Authors: Sun Tao , Li Zizhong 
Published: January 2020

AbstractHorizontal variability of soil water content (θ), soil surface water evaporation (E), and throughfall (TF) at the row scale have great influence on agricultural production, hydrological simulation and sampling strategy. The objective of the present study was to assess the horizontal variability and the most representative measurement position of θ, E, and TF at the corn (Zea mays L.) row scale in a field experiment. Five measurement positions of P0, P15, P30, P45 and P60 were at 0, 15, 30, 45 and 60 cm from the corn row line, respectively. The horizontal variability of θ mainly existed in 0–15 cm soil layer (P = 0.031). The coefficient of variation (CV) of the θ of 0–15, 30, and 50 cm ranged from 7.0–25.1%, 4.1–10.2%, and 5.3–11.4%, respectively. The CV of the E and TF ranged from 9.9–27.2% and 20.4–35.6%, respectively. The P15 or P45 was regarded as the most representative measurement position for measuring the θ of 0–15, 30, and 50 cm, with a probability of 51.0–58.8%, 43.1–43.1%, and 54.9–60.8%, respectively, and that for TF was 93.9–84.8%. The probability of P15 as the most representative measurement position to determine E was 61.1%. Therefore, horizontal variability of θ, E, and TF in a row‐planted crop field could not be ignored. The P15 was the most representative measurement position of θ, E, and TF in such an experimental condition.
Associations between lifetime stress exposure and prenatal health behaviors

Published: January 2020

AbstractPrenatal health behaviors can strongly influence risk of poor pregnancy birth outcomes. Although stress has been implicated in structuring the likelihood that individuals will engage in various prenatal health behavior patterns, no studies to date have examined life stress exposure occurring across the entire lifespan, and few have investigated how different types of stressors are comparatively associated with these outcomes. To address these issues, we interviewed 164 women at one of two large Midwestern, urban hospitals after delivering their first infant. We used the Stress and Adversity Inventory (STRAIN) to assess women's lifetime stress exposure severity and ordinary least squares regression models to examine associations between participants' life stress exposure and prenatal health behaviors. As hypothesized, greater lifetime stress exposure was associated with engaging in more negative prenatal health behaviors and fewer positive prenatal health behaviors while controlling for relevant sociodemographic factors and current perceived stress levels. These effects were stronger for negative versus positive health behaviors, and they differed substantially as a function of stressor type, exposure timing, and primary life domain. Stressors occurring over the life course thus have negative consequences for prenatal health behaviors, but these effects are not uniform across different types of life stress exposure.

Published: January 2020

AbstractMesoporous nanoparticles as a versatile platform for cancer theranostics have been widely used, but their cellular delivery efficiency is still far from satisfactory. Although deformability is emerging as an important parameter influencing cellular uptake enhancement, the facile synthesis of deformable mesoporous nanocomposite with adjustable mechanical property is challenging but meaningful for a deeper understanding of cellular uptake mechanisms and significantly improving cancer therapy. In this work, yolk–shell structured eccentric mesoporous organosilica (YEMO) nanocomposites with adjustable mechanical property are successfully prepared by an organosilane‐assisted anisotropic self‐assembly approach. The feasibility to precisely control the mechanical property of the YEMO by manipulating the structural parameters, the crosslinking degree of mesoporous framework, and the rotation rate of the reaction is demonstrated. The study of the fabrication mechanism and mechanical properties of YEMO are discussed in detail. The Young's modulus (EY) of YEMO can be adjusted from 2.4 to 65 MPa. Thereby, the continuous control of the cellular uptake from ≈15% to ≈80% under the same incubation time is achieved. To further prove the higher efficiency drug delivery of YEMO with soft characteristics, the higher toxicity of the “soft” YEMO loaded with the anticancer drug doxorubicin compared to the “stiff” one is demonstrated.
