Distribution STATCOM with optimal phase angle injection model for reactive power compensation of radial distribution networks
Authors: Sanam Joseph , Ganguly Sanjib , Panda A.K. 
Published: April 2017

AbstractIn this paper, a distribution static compensator (DSTATCOM) model based on optimal angle injection is devised and used in reactive power compensation of radial distribution systems. In the proposed DSTATCOM model, the rating of the DSTATCOM is determined with the injection of optimal phase angle of the voltage at the location, in which a DSTATCOM is placed. The proposed DSTATCOM model is suitably incorporated in the forward‐backward sweep load flow algorithm. The optimal location and rating for DSTATCOM are determined by minimizing the active power loss of a distribution network. Differential evolution algorithm is used as the solution strategy. The 69‐bus radial distribution system is used in the case study. The results show that the proposed approach is more efficient in active power loss reduction as compared with some of the previously published approaches.

We aimed to develop an efficient cleanup method for multi‐pesticides residue analysis in complex plant matrices, shallot, ginger, garlic, onion, leek, and celery. Column chromatography was used as the cleanup method and fabricated with florisil and graphitized carbon black as the adsorbents. The amount of the graphitized carbon black adsorbent and the choice of the elution solvent were systematically investigated for exploring the best combination. The target pesticides covered organochlorine, pyrethroid, and organophosphorus pesticides, and were 38 in total. The method validation and comparison were performed to verify its feasibility and advantages in operation convenience and purification efficiency. The method limit of quantitation varied from 0.01 to 0.03 mg/kg, which depends on the pesticides and the sample matrices. The recoveries of the pesticides ranged from 60.5 to 128% (RSD ≤ 19.0%) at the spiked concentration level of 0.01 (or 0.03) mg/kg and 62.9 to 130% (RSD ≤ 13.0%) at 0.1 mg/kg. Compared with the commercial cleanup solid‐phase extraction cartridges, the present adsorbent combination displayed better purification effect and shorter sample pretreatment time, demonstrating potential application prospect in the complex matrix sample analysis.

Educational ObjectiveObjective metrics in skilled‐based educational courses allow trainees and instructors to assess performance and monitor progress. The objective is to validate a concise, easy‐to‐use instrument for assessment of resident skill during a timed cadaveric temporal‐bone (CTB) dissection.Study DesignRetrospective analysis.MethodsAn instrument was developed to assess resident performance on a yearly timed microdissection of CTB. Five neurotologists participated in the assessment. Each reviewer's score was compared to the score given by the senior neurotologist each year for every resident. Spearman's correlation analysis was then used to assess the reproducibility of the instrument in assessing resident performance. The ability of the instrument to distinguish among experienced and novice trainees and to demonstrate improvement with experience were also assessed.ResultsThe instrument was created and used for 6 years. Thirty residents were assessed. Correlation of scores between the senior neurotologist and the other neurotologist together was very high (r = 0.883, P < 0.001). Three specific tasks distinguished novice from senior dissectors: posterior canal, opening the membranous labyrinth, and disruption of the ossicular chain.ConclusionA new instrument for assessment of resident skill on CTB dissection is presented. The instrument is easy to use, and scores derived from it are consistent across reviewers. The new instrument distinguishes experienced trainees from novice trainees, is sensitive to individual experience, and has proved useful in providing trainees with objective performance measures.Level of EvidenceNA.

Objectives/HypothesisTo investigate the incidence and complications related to postoperative hemorrhage (POH) after transoral robotic surgery (TORS).Study DesignRetrospective review of the State Inpatient Database (SID), the State Ambulatory Surgery Database (SASD), and the State Emergency Department Database (SEDD) from the Healthcare Cost and Utilization Project.MethodsPatients were identified from the SID, SASD, and SEDD for the states of Florida, New York, and California from 2005 to 2013 who had an International Classification of Diseases, Ninth Edition code for a surgical procedure on the upper aerodigestive tract associated with a code for robotic‐assisted surgery. Univariate logistic regression was used to explore factors associated with POH.ResultsFive hundred nine patients underwent TORS. Indications for surgery included neoplastic disease in 376 (74%) and sleep apnea in 74 (15%). Forty‐one (8%) had an episode of POH at a median of 9 days postoperatively (range = 0–21 days). Twenty‐four (5%) required an intervention related to their POH. Sixteen (3%) required return to the operating room for control of hemorrhage; 11 (2%) had a severe complication that required embolization or tracheostomy. Charlson Comorbidity Score of ≥3 (odds ratio [OR] = 3.02, 95% confidence interval [CI] = 1.45‐6.30) and a tonsillar neoplasm (OR = 1.96, 95% CI = 1.03‐3.74) were significantly associated with POH.ConclusionsThe incidence of POH after TORS was low, and few of these patients had a severe complication related to this event. Medical comorbidity and tonsillar subsite may be independent risk factors for POH. These data provide a benchmark for informed decision making in TORS and a basis for further study.Level of Evidence4. Laryngoscope, 127:2287–2292, 2017
The predation paradox: Synergistic and antagonistic interactions between grazing by crustacean predator and infection by cyanophages promotes bloom formation in filamentous cyanobacteria
Authors: Šulčius Sigitas , Slavuckytė Kristina , Paškauskas Ričardas 
Published: April 2017

AbstractIn this study, we assessed the impact of synergistic/antagonistic interactions between grazing by crustacean predator (Daphnia magna) and infection by cyanophage (Vb‐AphaS‐CL131) on the population dynamics of the harmful bloom‐forming filamentous cyanobacterium Aphanizomenon flos‐aquae. We observed synergistic effect of cyanophage infection on D. magna survival and grazing trough the lysis‐induced shift in cyanobacteria population structure toward the shorter filaments. However, lysis‐mediated‐ and grazing‐enhanced removal of short A. flos‐aquae filaments resulted in the dominance of grazing‐ and infection‐resistant A. flos‐aquae population. In addition, the presence of D. magna generated a trait‐mediated response in the A. flos‐aquae population by promoting the aggregation of filaments into colony‐like structures. Experiments using temperate A. flos‐aquae colony isolates from natural environment demonstrated that colony‐embedded A. flos‐aquae filaments are insensitive to the addition of both D. magna and cyanophages. Therefore, we propose that interactions between crustacean grazers and cyanophages may promote the emergence of defensive A. flos‐aquae genotypes and population traits that eventually lead to bloom formation in aquatic environments.

Published: April 2017

ABSTRACTLow dielectric photopatternable materials have aroused much interest owing to their potential application as alternatives of conventional photoresists. Although a number of photosensitive groups have been established to construct photopatternable materials for many years, it is still a challenge to introduce them into polymer chains via a facile and control polymerization technique, such as living free radical polymerization. In this work, on the basis of the photoactive silaycyclobutene moiety, a new monomer, 1‐methyl‐1‐(4‐vinylphenyl) silacyclobutane (1‐MVPSCB), was synthesized and demonstrated successful to conduct atom transfer radical polymerization (ATRP). Subsequently, the copolymerization of 1‐MVPSCB with 4‐vinylbenzocyclobutene (4‐VBCB) and styrene produced a kind of benzocyclobutene/silacyclobutane double‐crosslinked polymer (BS‐DCP) with controlled benzocyclobutene/silacyclobutane ratios and low polydispersity index. Owing to the UV/thermally dual crosslinked structure, BS‐DCP possesses photapatternability, high dimensional stability and low dielectric constant (2.37 at 10 MHz). These properties make BS‐DCP a potential photoresist that could be directly used as interconnected dielectrics. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2017, 55, 1920–1928
Photo‐oxidation of poly(2,6‐dimethyl‐1,4‐phenylene oxide): A reinvestigation
Authors: Pickett James E. 
Published: April 2017

ABSTRACTReinvestigation of poly(2,6‐dimethyl‐1,4‐phenylene oxide) photodegradation at wavelengths > 290 nm shows that both methyl groups and aromatic rings are sites of oxidation with their relative rates dependent on exposure conditions, based on infrared spectroscopy. The methyl group loss is linear with exposure and apparently proceeds by direct abstraction of a benzylic hydrogen by oxygen. The aromatic ring loss and carbonyl growth in the IR spectra appear to be auto‐accelerating and seem to proceed by electron transfer to oxygen, either sensitized or through a direct reaction with oxygen, and recombination of the polymer radical cation and superoxide to result in oxygen addition to the ring. Molecular weight loss in solution occurs to a significant degree only in the presence of oxygen, even in the presence of a hydrogen‐donating solvent, indicating that aryl ether photolysis is not a major pathway. © 2017 Wiley Periodicals, Inc.

Designing dual inhibitors of Mdm2/MdmX: Unexpected coupling of water with gatekeeper Y100/99
Authors: Lee Xiong An , Verma Chandra , Sim Adelene Y.L 
Published: April 2017

ABSTRACTMdm2 and MdmX share high structural similarity in their N‐terminal domains, yet dual inhibitors are challenging to design due to differences in the conformations of the binding pockets, and notably of the proposed gatekeeper residue, Y100/99. Analysis of crystal structures and molecular dynamics (MD) simulations of complexes of Mdm2 and MdmX resulted in the identification of a water molecule with a long residence time that appears to be modulated by the conformation of Y100/99. These observations lead us to speculate that dual inhibitors either (i) stabilize both Mdm2 and MdmX with Y100/99 in the open conformation typically seen in complexes of Mdm2 with p53, or (ii) the dual inhibitors are agnostic to the conformation of Y100/99. The recently developed potent dual inhibitory stapled peptide Atsp7041 appears to be agnostic to the conformation of the gatekeeper residue.

Hunter cooperation with requests to avoid a visibly marked ungulate

Published: April 2017

ABSTRACTStudies utilizing radio tags to examine animal space use are widespread and often require the survival of marked animals over the entirety of a specified study period to answer movement‐related questions. When studying the space use of game species, tactics such as applying visible markings to research animals and communicating with hunters may be needed to mitigate unwanted losses due to hunter harvest. Information regarding the effectiveness of visible markings and communication efforts in reducing harvest, as well as examples of hunter cooperation with requests to avoid harvesting marked animals, are lacking but could be quite useful when designing movement studies and planning capture efforts. Across 3 studies conducted during 2009–2015 on public and private land in the southeastern United States, adult white‐tailed deer (Odocoileus virginianus) were captured and marked in 1 of 3 ways: via conspicuous (Global Positioning System [GPS]) radiocollar; conspicuous radiocollar combined with visible ear tags; or cryptic (very‐high‐frequency [VHF]) radiocollar. Hunters were asked not to harvest visibly marked deer (GPS radiocollars, with or without ear tags) and survival was compared with that of cryptically marked (VHF) animals. Visibly marked deer were less likely to be harvested than were cryptically marked individuals on private land, but collar types were treated similarly on public land. Additionally, visibly marked males were more likely to be harvested than visibly marked females and the likelihood of harvest increased with male deer age. Our findings suggest that hunter cooperation decreases with the opportunity to harvest a “trophy” and that cooperation is lower on public land compared with private land. Insight into hunter treatment of visibly marked deer can inform researchers and managers about expected losses when conducting long‐term spatial monitoring of ungulates and other game species. © 2017 The Wildlife Society.

Published: April 2017

ABSTRACTWe report on the use and efficiency of an active mist‐net method for capturing 3 subspecies of torrent ducks (Merganetta armata), a territorial and specialized South American waterfowl, in fast‐moving rivers of the Andes Mountains. As an active process, the execution of this methodology required the presence of a well‐trained, 3‐person team. During the austral winter and spring between 2010 and 2014, we captured 372 torrent ducks in 410 capture events on 8 different rivers in Colombia (n = 1), Peru (n = 5), and Argentina (n = 2). Each captured torrent duck was banded and 38 opportunistic recaptures events were obtained using the same methodology in the same territories. We deployed the mist nets across fast‐moving deep rivers, along elevational gradients (680–4,200 m). Males were more easily captured than females, because of their greater tendency to fly. Our data validated this capture method for torrent ducks, as we succeeded in capturing individuals of the 3 subspecies in different habitats at different elevations and latitudes. To avoid animal mortality, we recommend application of this method only when 3 minimal conditions are met: 1) each field crew has ≥3 people; 2) all of the crew members have hand‐radios to enable continuous communication; and 3) each crew member has received prior training (e.g., installation, inspection, manipulation, and removal of the mist net, bird extraction, and familiarity with the behavior of the torrent ducks). © 2017 The Wildlife Society.

AbstractThe gut microbiota is proposed as a “metabolic organ” involved in energy utilization and is associated with obesity. Dietary intervention is one of the approaches for obesity management. Changes in dietary components have significant impacts on host metabolism and gut microbiota. In the present study, we examined the influence of dietary fat intervention on the modification of gut mucosa‐associated microbiota profile along with body weight and metabolic parameter changes. Male C57BL/6J mice (6‐week old) were fed a low fat diet (10% kcal fat) as a control or a high fat diet (HFD 60% kcal fat) for 7 weeks. In another group, mice were fed HFD for 5 weeks followed by low fat control diet for 2 weeks (HFD + Control). At 7 weeks, body weight gain, blood glucose and hepatic triacylglycerol levels of mice fed a HFD were significantly higher than that of the control group and the HFD + Control group. There were significant differences in the diversity and predicted functional properties of microbiota in the cecum and colon mucosa between the control group and the HFD group. HFD feeding reduced the ratio of Bacteroidetes to Firmicutes, a microbiota pattern often associated with obesity. The HFD + Control diet partially restored the diversity and composition of microbiota in the cecum to the pattern observed in mice fed a control diet. These results suggest that short‐term high fat diet withdrawal can restore metabolic changes and prevent excess body weight gain, however, long‐term dietary intervention may be required to optimize the restoration of gut microbiota in mouse.

Abstract
Samples of Triassic sediments were collected from cores of parametric boreholes drilled on the Admiralteiskii Rise, Franz Josef Land Archipelago, and Fersman structure in the northeastern part of the Barents Sea sedimentary basin. The composition and distribution of hydrocarbon biomarkers (n-alkanes, isoprenoids, cyclic alkanes, and polyaromatic hydrocarbons) were studied using the GC–MS method and provided information about the genesis, facies conditions of sedimentation, and catagenetic maturity stage of dispersed organic matter (DOM). The Late Mesozoic–Cenozoic uplifting of the region and active magmatic processes significantly influenced the thermal transformation of sediments. The revealed trend is best observed in the sediment section of the Franz Josef Land Archipelago, where the thermal effects led to a radical increase in DOM transformation, up to the AC1 stage.

AbstractAdulticides applied against mosquitoes can reduce vector populations during times of high arbovirus transmission. However, impacts of these insecticides on pollinators and other non-target organisms are of concern to mosquito control professionals, beekeepers and others. We evaluated mortality of Culex quinquefasciatus and Apis mellifera when caged insects were exposed to low and high label rates of four common adulticides (Aqua-Pursuit™ [permethrin], Duet® [prallethrin + sumithrin], Fyfanon® [malathion] and Scourge® [resmethrin]) at six distances up to 91.4 m from a truck-mounted ultra-low-volume sprayer. Honey bee mortality was both absolutely low (<10%) and low relative to mosquito mortality for most products, distances, and application rates. Exceptions were at the high rate of Fyfanon (honey bee mortality of 22–100% at distances ≤61 m) and the low rate of Scourge (mortality <10% for both insects). The greatest ratios of mosquito-to-honey bee mortality were found for the low rate of Fyfanon (30× greater) and the high rate of Duet (50× greater). Aqua-Pursuit and Fyfanon tended to increase mortality of both species at closer distances and at higher application rate; this was related to increased number and size of spray droplets. Wind speed and temperature had inconsistent effects on mortality of mosquitoes only. In this bioassay designed to have insects directly intercept insecticide droplets, mosquito adulticides applied at low rates and at >61 m had limited impacts on honey bee mortality while providing effective mosquito control.

AbstractWhile the trajectory of self-esteem from adolescence to adulthood varies from person to person, little research has examined how differences in early developmental processes might affect these pathways. This study examined how early motor skill development interacted with preterm birth status to predict self-esteem from adolescence through the early 30s. We addressed this using the oldest known, prospectively followed cohort of extremely low birth weight (<1000 g) survivors (N= 179) and normal birth weight controls (N= 145) in the world, born between 1977 and 1982. Motor skills were measured using a performance-based assessment at age 8 and a retrospective self-report, and self-esteem was reported during three follow-up periods (age 12–16, age 22–26, and age 29–36). We found that birth weight status moderated the association between early motor skills and self-esteem. Stable over three decades, the self-esteem of normal birth weight participants was sensitive to early motor skills such that those with poorer motor functioning manifested lower self-esteem, while those with better motor skills manifested higher self-esteem. Conversely, differences in motor skill development did not affect the self-esteem from adolescence to adulthood in individuals born at extremely low birth weight. Early motor skill development may exert differential effects on self-esteem, depending on whether one is born at term or prematurely.
