Impacts of the Cryosphere and Atmosphere on Observed Microseisms Generated in the Southern Ocean

The Southern Ocean (in the region 60–180° E) south of the Indian Ocean, Australia, and the West Pacific is noted for the frequent occurrence and severity of its storms. These storms give rise to high‐amplitude secondary microseisms from sources, including the deep ocean regions, and primary microseisms where the swells impinge on submarine topographic features. A better understanding of the varying microseism wavefield enables improvements to seismic imaging and development of proxy observables to complement sparse in situ wave observations and hindcast models of the global ocean wave climate. We analyze 12–26 years of seismic data from 11 seismic stations either on the East Antarctic coast or sited in the Indian Ocean, Australia, and New Zealand. The power spectral density of the seismic wavefield is calculated to explore how the time‐changing microseism intensity varies with (i) sea ice coverage surrounding Antarctica and (ii) the Southern Annular Mode (SAM) climate index. Variations in sea ice extent are found to be the dominant control on the microseism intensity at Antarctic stations, which exhibit a seasonal pattern phase‐shifted by 4–5 months compared to stations in other continents. Peaks in extremal intensity at East Antarctic stations occur in March–April, with the highest peaks for secondary microseisms occurring during negative SAM events. This relationship between microseism intensity and the SAM index is opposite to that observed on the Antarctic Peninsula. This work informs the complexity of microseism amplitudes in the Southern Hemisphere and assists ongoing interdisciplinary investigations of interannual variability and long‐term trends.
Utilisation de centres NV comme capteurs de champs magnétiques à haute pression dans des cellules à enclumes de diamant

La pression est un parametre physique qui modifie les interactions structurales, electroniques et magnetiques dans les materiaux. Creer une tres haute pression permet donc la synthese de nouveaux materiaux, comme par exemple des supraconducteurs ayant des valeurs de temperature critique record. Ces pressions peuvent etre generees au moyen d’une cellule a enclume de diamant (DAC) qui peut comprimer un materiau jusqu’a des pressions de plusieurs centaines de GPa. Il est cependant difficile de caracteriser les proprietes magnetiques de materiaux a l’interieur d’une DAC a cause du tres faible volume occupe par l’echantillon et des contraintes techniques. Dans cette these, nous proposons d’utiliser une technique de magnetometrie optique fondee sur la resonance de spin electronique de centres colores NV du diamant. Ces centres NV sont fabriques a la surface d’une des deux enclumes de la DAC et sont ainsi au contact de l’echantillon magnetique a caracteriser.Dans un premier chapitre, nous rappelons le fonctionnement de la DAC et decrivons les techniques de mesures magnetiques developpees pour la physique des hautes pressions. Nous presentons ensuite le principe de la magnetometrie a centres NV et l’appliquons a la mesure de l’aimantation d’un micro-aimant a pression ambiante. La sensibilite de cette mesure atteint celle des magnetometres a SQUID. Le troisieme chapitre discute de la facon dont les contraintes mecaniques modifient la resonance de spin du centre NV, et detaille la maniere dont cet effet se combine avec celui du a un champ magnetique externe. La possibilite de decoupler les deux effets nous permet d’observer la transition de phase magnetique du fer autour de 15 a 30 GPa dans le quatrieme chapitre. Enfin, le dernier chapitre decrit le contexte et les enjeux lies a la synthese d’hydrures supraconducteurs a haute temperature critique. Nous montrons ensuite qu’il est possible de detecter optiquement une phase supraconductrice a l’interieur d’une DAC en utilisant les centres NV pour observer l’effet Meissner de MgB2 a une pression de 7 GPa et avec une temperature critique de 30 K.
A Bidirectional Study between Rheumatoid Arthritis and Sjogrens Syndrome: A Population-based Cohort Study in Taiwan

Both of rheumatoid arthritis (RA) and Sjogren’s syndrome (SS) are long-term autoimmune disorders. Meanwhile, RA tends to be more complicated than SS. Although there have been lots of studies about RA and SS, less research focused on their bidirectional effects. The major purpose of this study is to evaluate the risks between RA and SS. We build two datasets collected from Longitudinal Health Insurance Database (LHID) during the periods between 2006 and 2013. One is about 8469 patients with RA and 42,345 (1:5) age group-, and sex-matched non-RA controls. The other is regarding 8229 patients with SS and 41,145 (1:5) age group-, and sex-matched non-SS controls. We estimated hazard ratios (HRs) using Cox proportional hazard models in both datasets. We found that the risk of suffering SS in patients with RA (HR 3.29) is higher than the risk of suffering RA in patients with SS (HR 1.64), compared to the corresponding control cohorts, respectively. Additionally, for the RA case cohort, if patients had suffered from comorbidities such as hyperlipidemia (HR 1.28), autoimmune disease (HR 4.83), and gout (HR 1.61) before suffering RA, they would further have had higher risk of suffering SS than patients without these comorbidities.
PD-L1 and CD8 expression and association with outcomes in patients (pts) with BRAF V600E/K–mutant metastatic melanoma (MM) who received dabrafenib + trametinib (D+T) in the randomized phase 3 COMBI-v study.

183Background: The phase 3 COMBI-v study (NCT01597908) showed that D+T significantly improved outcomes vs vemurafenib in pts with BRAF V600E/K–mutant MM. Checkpoint inhibitors also provide clinical benefit in some pts with MM. To date, characterization of markers associated with response to anti–PD-1 therapy has identified positive associations with PD-L1 expression and immune cell infiltration. Here we describe expression of PD-L1 and the T-cell marker CD8 in tumor samples from pts randomized to receive D+T in COMBI-v and associations with clinical outcomes. Methods: Biopsies from 74 of 352 D+T pts (21%) in COMBI-v were assessed for expression of PD-L1 (PD-L1 IHC 22C3 pharmDx assay; Dako) and CD8 (anti-CD8 antibody, clone C8/144B; Dako). PD-L1 positivity was determined as a percentage of stained tumor cells and MEL score (staining on both tumor and mononuclear inflammatory cells; 0 or 1 [negative]: < 1% staining; 2-5 [positive]: ≥ 1% staining; Daud et al. J Clin Oncol. 2016). Results: Of 74 pts analyzed,.
A Planar Location Method for DC Arc Faults Using Dual Radiation Detection Points and DANN

Arc faults in dc microgrids or photovoltaic (PV) systems are difficult to detect and isolate. Especially in location research, there are few related results, and arc fault detection is immature. This article proposes a planar location method that requires only two detection points. Because the height of many dc systems is much smaller than their horizontal dimension, an antenna array and a fault source form a horizontal triangle to locate the dc arc faults. Then, the signal pulses are distinguished and extracted using a cross correlation technique. A neural network (NN) and received signal strength indicators (RSSIs) are used to estimate the arc distance. However, the data from the dual detection points are insufficient for meeting the demands of NN training and may lead to a large location error. Therefore, a data-augmented NN (DANN) technique was introduced into the algorithm to enhance the accuracy and robustness of distance estimation. The experimental verification results show that the method can effectively locate faults under a variety of arcing conditions. Moreover, the proposed method has intrinsic immunity to normal current fluctuations (NCFs). It can be used in PV plants or smart buildings with solar cells to avoid nuisance trips and improve the effectiveness of fault protection.
Impact Analysis of Univariate and Multivariate Bias Correction on Rice Irrigation Water Needs in Jiangxi Province, China

Regional climate models (RCMs) provide an improved representation of climate information as compared to global climate models (GCMs). However, in climate-agricultural impact studies, accurate and interdependent local-scale climate variables are preferable, but both RCMs and GCMs are still subjected to bias. This study compares univariate bias correction (UBC) and multivariate bias correction (MBC) method to simulate rice irrigation water needs (IWNs) in Jiangxi Province, China. This research uses the daily output of Hadley Centre Global Environmental Model version 3 regional climate model (HadGEM3-RA) forced with ERAINT (ECMWF ERA Interim) data and 13 Jiangxi ground-based observations, and the observation data are reference data with 1989–2005 defined as a calibration period and 2006–2007 as a validation period. The result shows that UBC and MBC methods favorably bias-corrected all climate variables during the calibration period, but still no significant difference is noted between the two methods. However, the UBC ignores the relationship between climate variables, while MBC preserves the climate variables’ interdependence which affect subsequent analyses. In rice IWNs simulation analysis, MBC has better skill at correcting bias compare to UBC in ETo (evapotranspiration) and Peff (effective rainfall) components. Nonetheless, both methods have a low ability to correct extreme values bias. Overall, both techniques successfully reduce bias, even though they are still less effective for precipitation compared to maximum and minimum temperature, relative humidity and windspeed.
Coupled Flexural and Torsional Vibration Analysis of Composite Beams

An analytical method is presented to determine the dynamic response of a coupled flexural and torsional vibration of composite beams. The general governing equations of motion are presented and a closed form solution for free vibration of the composite beam that demonstrates both geometric and material coupling is developed. The proposed solution is used to compute the natural frequencies, modal loss factors, and mode shapes of the composite beam for several modes of the coupled bending and torsional vibrations for any boundary conditions. In this analysis, hysteretic damping for the composite beam is considered and its effects on mode shapes and modal loss factors are determined. In addition, the variation of modal parameters such as bending displacement, bending slope, torsional rotation, shear force, bending moment, and torque along the beam for the first four mode shapes are presented for the clamped-free boundary conditions. Moreover, to verify the validity of the presented analytical method, results for the cases with no damping are compared with the previously established results and good agreement is achieved. The presented results can provide a guideline for selecting appropriate geometries and materials to design composite beams.
Presumptive Treatment of Chlamydia and Gonorrhea Infections in a Canadian Ambulatory Emergency Department Setting: Determination of Overtreatment and Undertreatment Rates

Objectives Presumptive antibiotic treatment may be given for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) infections before a laboratory diagnosis is established, but overtreatment can increase resistance rates. We sought to determine the presumptive treatment prevalence in our emergency department (ED) setting, as well as the number of overtreated and undertreated patients. Methods We performed a retrospective cohort study of all patients tested for CT/GC in an urban academic ED during a 6-month period in 2015. Presumptive treatment prevalence, overtreatment and undertreatment proportions, and CT- and GC-positive test proportions were calculated with 95% Wald confidence interval (CI) and compared across age and sex. Results Of 209 included cases (male n = 3, female n = 206), 27 (13%; CI, 8%–18%) received presumptive treatment for CT and 19 (9%; CI, 5%–14%) for GC. Seven cases (3%; CI, 1%–6%) were positive for CT and 0 for GC. Of the 7 CT-positive cases, 2 (29%) received presumptive treatment in the ED, and 5 (71%) were treated after the positive test results were obtained. There was no loss to follow-up. Mean delay to treatment was 10 days, including a mean of 3 days for laboratory analysis. Overtreatment and undertreatment proportions were 93% (CI, 83%–100%) and 3% (CI, 0%–5%) for CT and 100% and 0% for GC, respectively. Positive test result, presumptive treatment, overtreatment, and undertreatment were not associated with age or sex. Conclusions Given the low CT/GC incidence and good follow-up, at our institution, it would be reasonable to wait for a laboratory diagnosis rather than give presumptive treatment.

Deep Multiphysics and Particle–Neuron Duality: A Computational Framework Coupling (Discrete) Multiphysics and Deep Learning

There are two common ways of coupling first-principles modelling and machine learning. In one case, data are transferred from the machine-learning algorithm to the first-principles model; in the other, from the first-principles model to the machine-learning algorithm. In both cases, the coupling is in series: the two components remain distinct, and data generated by one model are subsequently fed into the other. Several modelling problems, however, require in-parallel coupling, where the first-principle model and the machine-learning algorithm work together at the same time rather than one after the other. This study introduces deep multiphysics; a computational framework that couples first-principles modelling and machine learning in parallel rather than in series. Deep multiphysics works with particle-based first-principles modelling techniques. It is shown that the mathematical algorithms behind several particle methods and artificial neural networks are similar to the point that can be unified under the notion of particle–neuron duality. This study explains in detail the particle–neuron duality and how deep multiphysics works both theoretically and in practice. A case study, the design of a microfluidic device for separating cell populations with different levels of stiffness, is discussed to achieve this aim.
Mobile Edge Computing Meets mmWave Communications: Joint Beamforming and Resource Allocation for System Delay Minimization

Mobile edge computing (MEC) has been identified as a key technique of next-generation wireless networks, which supports cloud computing along with other compelling service capabilities at the network’s edge with the objective of reducing the system delay. As one of the prospective candidates for new spectrum in next-generation networks, millimeter wave (mmWave) communications has been gaining significant attention as a benefit of its high rate. Hence we conceive a joint hybrid beamforming and resource allocation algorithm for mmWave MEC. Explicitly, we jointly optimize the analog beamforming vectors at the users, the analog and digital beamforming matrices at the base station (BS), the computation task offloading ratios and resource allocation at the MEC server for minimizing the maximum system delay subject to the affordable communication and computing budget. We conceive a powerful algorithm for solving this challenging nonconvex optimization problem with coupled constraints based on the penalty dual decomposition (PDD) technique. The proposed algorithm can be implemented in a parallel and distributed fashion. Our numerical results demonstrate the superiority of the proposed algorithm by quantifying the benefits of intrinsically amalgamating MEC with mmWave communications.

Effects of auxin and urea derivatives on adventitious rooting in chestnut and oak microshoots

The present study investigated how auxin concentration and the method of application affected the formation of adventitious roots in microshoots of chestnut (Castanea sativa) and oak (Quercus robur). The activity of two urea derivatives (2, 3-MDPU and 3, 4-MDPU) was also evaluated. Microshoots were derived from basal sprouts of two mature chestnut trees (P1 and P2) and one adult oak genotype (Sainza). In chestnut, rooting percentage was positively affected by auxin in a dose -dependent manner, particularly in shoots treated with the hormone for 24 h. The effect of auxin on rooting also differed depending on the application method. In shoots treated for 24 h, the highest concentration of auxin produced the healthiest rooted plantlets, in terms of the root system and shoot quality. By contrast, in shoots treated by the basal quick-dip method, the shoot quality was best at the lowest auxin concentration. The effect of urea derivatives on the root system depended on the species as well as on the auxin concentration and application period. Use of the MDPUs improved the root system architecture of auxintreated shoots by promoting lateral root development and triggering the synchronous initiation of root primordia at the base of the shoot. Shoot quality was also improved by MDPUs, which promoted resumption of growth and reduced shoot-tip necrosis.
Isolated internal jugular vein thrombosis presenting with seizure: a case report

Background: Internal jugular vein thrombosis (IJVT) is an obscure vascular disease that is not often seen, with potentially deadly complications such as sepsis and pulmonary embolism. Spontaneous IJVT is considered when no obvious predisposing causes of thrombosis are present within the vessel. Case Presentation: A previously healthy, 27-year-old man presented to the emergency department in Al Noor hospital in Makkah complaining of right side neck pain and tonic seizure. Physical examination revealed mild swelling in the right anterior side of the neck with slight tenderness. Both CT scan and ultrasonography of the neck revealed an acute thrombus in the right internal jugular vein. The patient was started on anticoagulants and the neck pain relieved within 3 days. Results: The patient was discharged on Warfarin with weekly follow up in the clinic for monitoring of INR and PT. Conclusion: Even though spontaneous IJVT is a rare incidence, physicians should not exclude IJVT even in non-hospitalized patients and without risk factors. If there is a suspicion of IJVT, color Doppler U/S should be performed to exclude the disease.

Overall L2 proficiency maintenance and development among returning ERASMUS study abroad participants

Abstract This study examines the sustainability of gains in overall English proficiency made by 81 German students on ERASMUS study abroad placements in the UK (lasting one term or one academic year) following their return to their home country. Students were tracked using C-tests and questionnaires from pre-study abroad up until nine months post-return. Their development was compared with that of 25 peers who applied for ERASMUS placements, but continued studying at home. The analysis presented focuses on the post-return phase and includes factors associated with individual differences in L2 proficiency development post-return, self-perceived L2 skills development, and returnees’ perceived needs regarding further language classes. Results show that students tended to sustain gains in overall L2 proficiency made during study abroad. L2 proficiency level achieved by the end of study abroad, self-efficacy in using the L2 in social interactions, and majoring in English were all positively associated with post-return L2 development.
Body Weight Perception, Mental Health, and Weight Control Behavior in Normal Weight Adolescents: Based on the Korea National Health and Nutrition Examination Survey 2013-2015

Purpose: The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception. Methods: Study data on 12-18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). Rao-Scott Chi-square test and ANOVA were used for the analysis. Results: The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise. Conclusion: Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.
