Symptoms of problematic feeding in children with CHD compared to healthy peers
Authors: Pados Britt F.
Published: November 2018

Children with CHD often experience difficulty with oral feeding, which contributes to growth faltering in this population. Few studies have explored symptoms of problematic feeding in children with CHD using valid and reliable measures of oral feeding. The purpose of this study was to describe symptoms of problematic feeding in children with CHD compared to healthy children without medical conditions, taking into account variables that may contribute to symptoms of problematic feeding. Oral feeding was measured by the Pediatric Eating Assessment Tool, a parent report assessment of feeding with evidence of validity and reliability. This secondary analysis used data collected from web-based surveys completed by parents of 1093 children between 6 months and 7 years of age who were eating solid foods by mouth. General linear models were used to evaluate the differences between 94 children with CHD and 999 children without medical conditions based on the Pediatric Eating Assessment Tool total score and four subscale scores. Covariates tested in the models included breathing tube duration, type of CHD, gastroesophageal reflux, genetic disorder, difficulty with breast- or bottle-feeding during infancy, cardiac surgery, and current child age. Children with CHD had significantly more symptoms of problematic feeding than healthy children on the Pediatric Eating Assessment Tool total score, more physiologic symptoms, problematic mealtime behaviours, selective/restrictive eating, and oral processing dysfunction (p <0.001 for all), when taking into account relevant covariates. Additional research is needed in children with CHD to improve risk assessment and develop interventions to optimise feeding and growth.
A revised ontogeny of the early Ordovician trilobite Leptoplastides salteri (Callaway, 1877)
Authors: MÅNSSON Kristina , CLARKSON Euan N. K.
Published: November 2018

The ontogeny of the pelturine olenid trilobite Leptoplastides salteri (Callaway, 1877) from the Shineton Shales, Shropshire, England, was first described in 1925 by Frank Raw. Since that time, scanning electron microscopy and other new technologies have revealed many more details of structure, of early developmental stages in particular, than were available to Raw. Whereas protaspides are not preserved and the state of preservation is less than perfect for the smallest meraspides, we have established that the latter had an array of delicate, long thoracic and pygidial spines, as well as paired procranidial spines, which disappear by meraspid degree 8. Raw's reconstructions of early meraspides, and his measurements of the early stages in development, are here amended in the light of new information. Dorsal spines in the adult are much more highly developed than have been documented in any other olenid. The hypostome is preserved in place in several specimens. Initially conterminant (attached to the doublure), it becomes natant (free) in late meraspid to early holaspid stages of development, with its anterior contour fitting exactly to that of the glabella. The ecology of the widespread Leptoplastides is best known from very extensive sections in South America, which provide a useful basis for comparison. It was well adapted to a range of environments, both oxygenated and dysoxic, and is usually the dominant taxon in the biofacies in which it is found.
Freude am Denken als Schlüssel zum Erfolg? Die Bedeutung von Need for Cognition für subjektives Erleben und Leistung im Studium
Authors: Grass Julia , John Nancy , Strobel Anja
Published: November 2018

Zusammenfassung.Need for Cognition (NFC) beschreibt interindividuelle Unterschiede in der Freude an und der Beschäftigung mit anspruchsvollen kognitiven Aufgaben. Bisherige Forschung im akademischen Kontext untersuchte NFC vorrangig im Zusammenhang mit kognitiven und leistungsbezogenen Variablen. In dieser Studie wurde hingegen die Bedeutung von NFC für Erfolg im Studium insbesondere für subjektives Erleben untersucht. Für ein besseres Verständnis wurde die vermittelnde Rolle der regulativen Merkmale Selbstkontrollkapazität, Strategien der Emotionsregulation und Copingverhalten geprüft. Untersucht wurden Lehramtsstudierende (N = 167) als Gruppe, die bereits im Studium eine erhöhte Beanspruchung zeigt. Erwartungskonform hing NFC mit fast allen regulativen Merkmalen zusammen. Bezogen auf Studienerfolg wurden die Annahmen nur teilweise bestätigt: NFC war mit besseren Studienleistungen und einer höheren subjektiven Leistungsfähigkeit assoziiert. Dabei wurde die Vorhersage wahrgenommener Leistungsfähigkeit über regulative Merkmale vermittelt. Zukünftige Studien sollten untersuchen, weshalb in dieser Stichprobe nur ein Teil der Erlebensaspekte mit NFC zusammenhingen und die Ergebnisse für Studierende anderer Fächer prüfen.
Elterliche Geschlechterrollenvorstellungen, familiärer Hintergrund und Schulleistungen
Authors: Lühe Josefine , Becker Michael , Maaz Kai
Published: November 2018

Zusammenfassung. Geschlechterunterschiede in Schulleistungen stellen einen vielfach berichteten Befund dar. In Anlehnung an das Erwartungs-Wert-Modell ( Eccles et al., 1983 ; Eccles, 2015 ) kann davon ausgegangen werden, dass die Geschlechterrollenvorstellungen der Eltern ihr Erziehungsverhalten beeinflussen. Vor diesem Hintergrund wird der Zusammenhang zwischen den elterlichen Geschlechterrollenvorstellungen und den Mathematik- und Deutschleistungen ihres Grundschulkindes (N = 5240) untersucht. Darüber hinaus wird analysiert, in welchem Zusammenhang die elterlichen Geschlechterrollenvorstellungen mit familiären Hintergrundmerkmalen stehen. Die Ergebnisse aus Regressionsanalysen zeigen, dass ein höherer sozioökonomischer Status mit egalitäreren Einstellungen einhergeht, während ein Migrationshintergrund (türkisch, osteuropäisch, andere Herkunftsländer) mit traditionelleren Einstellungen assoziiert ist. Traditionelle Geschlechterrollenvorstellungen stehen für Jungen und Mädchen gleichermaßen in einem negativen Zusammenhang mit ihren Deutsch- und Mathematikleistungen. Dieser Effekt bleibt auch unter Kontrolle familiärer Hintergrundmerkmale statistisch signifikant.

The 16‐Day Planetary Wave Triggers the SW1‐Tidal‐Like Signatures During 2009 Sudden Stratospheric Warming
Authors: He Maosheng , Chau Jorge Luis , Hall Chris M. , Tsutsumi Masaki , Meek Chris , Hoffmann Peter
Published: November 2018

Enhanced nonmigrating tides SW1 (SWx represents semidiurnal westward mode with zonal wave number x) and SW3 during sudden stratospheric warming (SSW) were traditionally attributed to nonlinear interactions of quasi‐stationary planetary waves with the migrating tide SW2. Recent studies specified hypothetically that responsible for the interactions is the 16‐day wave, instead of the broadly accepted quasi‐stationary planetary waves. It is suspected that the 16‐day‐wave‐triggered secondary waves, at periods ∼12.4 and ∼11.6 hr, were detected at low‐frequency resolutions and misinterpreted as SW1 and SW3, respectively. While He et al. (2018, https://doi.org/10.1002/2018JD028400) associated the 11.6‐hr oscillation conclusively to the SW3‐like signature during SSW 2013 by diagnosing its wave number, the SW1‐like 12.4hr wave, however, has never been explicitly resolved, given its proximity to the period of an active lunar tide. Here, using the coherency in the mesospheric wind between two longitudinal sectors during SSW 2009, we identify a 12.4‐hr oscillation dominated by wave number 1 and therefore associate it to the SW1‐like signature.

This study validates aerosol properties retrieved using a Satellite Ocean Aerosol Retrieval (SOAR) algorithm applied to Visible Infrared Imaging Radiometer Suite (VIIRS) measurements, from Version 1 of the VIIRS Deep Blue data set. SOAR is the over‐water complement to the over‐land Deep Blue algorithm and has two processing paths: globally, 95% of pixels are processed with the full retrieval algorithm, while the 5% of pixels in shallow or turbid (mostly coastal) waters are processed with a backup algorithm. Aerosol Robotic Network (AERONET) data are used to validate and compare the midvisible (550 nm) aerosol optical depth (AOD), Ångström exponent (AE), and fine mode fraction of AOD at 550 nm (FMF). AOD uncertainty is shown to be approximately ±(0.03 + 10%) for the full and ±(0.03 + 15%) for the backup algorithms, with a small positive median bias around 0.02. When AOD is below about 0.2, the AE and FMF have small negative offsets from AERONET around −0.15 and −0.04, respectively. For higher AOD, AE is less offset and the magnitudes of differences versus AERONET are about ±0.2 and ±0.14, respectively. Aerosol‐type classifications provided by SOAR are found to be reasonable, matching optical‐based classifications from AERONET over 80% of the time. Spatial and temporal patterns of AOD and AE are also compared with those of other contemporary over‐water satellite aerosol data sets; dependent on region, the satellite data sets show varying levels of consistency, with SOAR broadly in‐family, and the largest discrepancies in regions with persistent heavy cloud cover.

Leaf‐cutter ants are dominant herbivores that disturb the soil and create biogeochemical hot spots. We studied how leaf‐cutter ant Atta cephalotes impacts soil CO2 dynamics in a wet Neotropical forest. We measured soil CO2 concentration monthly over 2.5 years at multiple depths in nonnest and nest soils (some of which were abandoned during the study) and assessed CO2 production. We also measured nest and nonnest soil efflux, nest vent efflux, and vent concentration. Nest soils exhibited lower CO2 accumulation than nonnest soils for the same precipitation amounts. During wet periods, soil CO2 concentrations increased across all depths, but were significantly less in nest than in nonnest soils. Differences were nonsignificant during drier periods. Surface efflux was equal across nest and nonnest plots (5 μmol CO2 m−2 s−1), while vent efflux was substantially (103 to 105 times) greater, a finding attributed to free convection and sporadic forced convection. Vent CO2 concentrations were less than in soil, suggesting CO2 efflux from the soil matrix into the nest. Legacy effects in abandoned nests were still observable after more than two years. These findings indicate that leaf‐cutter ant nests provide alternative transport pathways to soil CO2 that increase total emissions and decrease soil CO2 concentrations, and have a lasting impact. Estimated total nest‐soil CO2 emissions were 15 to 60% more than in nonnest soils, contributing 0.2 to 0.7% to ecosystem‐scale soil emissions. The observed CO2 dynamics illuminate the significant carbon footprint of ecosystem engineer Atta cephalotes and have biogeochemical implications for rainforest ecosystems.

Epilepsy is a major public health problem worldwide. Despite multiple drug therapies, people with epilepsy continue to have frequent seizures. There is a dearth of data on epilepsy treatment outcome and associated factors in our setting. Therefore, the aim of this was to assess treatment outcome and associated factors among epileptic patients on follow up at the neurologic clinic of Ayder comprehensive specialized hospital, Ethiopia. A cross-sectional study was conducted on randomly selected epileptic patients. Data were collected through patient interview and review of medical records. Epilepsy treatment outcome was evaluated in terms of seizure control status in the last one year follow up period. Binary logistic regression analysis was performed to identify predictors of treatment outcome. A total of 270 patients were included. Of whom, 46.6% had controlled seizures. Whereas, 38.5%, 8.8%, and 5.9% had experienced seizure attacks 1–5 times, 6–10 times, and greater than 10 times, respectively. Alcohol consumption [adjusted odds ratio [(AOR): 14.87, 95% confidence interval (CI): 3.25–68.11], negative medication belief [AOR: 3.0, 95%CI: 1.31–6.71], low medication adherence [AOR:11.52, 95%CI: 3.25–40.82], and presence of comorbidities [AOR: 10.35, 95%CI: 4.40–24.40] were predictors of uncontrolled seizure. Our finding revealed that more than half of the epileptic patients had uncontrolled seizure. Epileptic patients with a negative medication belief, comorbidities, low medication adherence, and those who consume alcohol were more likely to have uncontrolled seizure. Therefore, more emphasis should be given to these patients.

Published: November 2018

Radiology images are an essential part of clinical decision making and population screening, e.g., for cancer. Automated systems could help clinicians cope with large amounts of images by answering questions about the image contents. An emerging area of artificial intelligence, Visual Question Answering (VQA) in the medical domain explores approaches to this form of clinical decision support. Success of such machine learning tools hinges on availability and design of collections composed of medical images augmented with question-answer pairs directed at the content of the image. We introduce VQA-RAD, the first manually constructed dataset where clinicians asked naturally occurring questions about radiology images and provided reference answers. Manual categorization of images and questions provides insight into clinically relevant tasks and the natural language to phrase them. Evaluating with well-known algorithms, we demonstrate the rich quality of this dataset over other automatically constructed ones. We propose VQA-RAD to encourage the community to design VQA tools with the goals of improving patient care.

Integration of ROS and RT tasks using message pipe mechanism on Xenomai for telepresence robot
Authors: Delgado R. , You B.‐J. , Han M. , Choi B.W.
Published: November 2018

A promising approach integrating non‐real‐time (NRT) robot operating system (ROS) packages and RT tasks is proposed to enhance the development of RT robot control applications. Since ROS alone does not provide RT properties essential for achieving precise control period in manipulating multiple devices and complicated software, Xenomai, an RT extension of Linux is adapted. However, using NRT ROS packages inside RT tasks triggers mode switching that causes inability to satisfy critical temporal constraints. To address this issue, a message pipe mechanism termed cross‐domain datagram protocol (XDDP) is applied. In comparison to traditional inter‐task mechanisms, XDDP provides a communication interface between RT and NRT tasks. This greatly improves robot application development utilising ROS tools and packages with RT tasks on the Xenomai domain ensuring priority‐based scheduling and deterministic response in a multitasking environment. Feasibility of the proposed method was validated for practical use by realisation on the open embedded controller for a telepresence robot. Experiments were conducted to actuate the mobile base of the robot using ROS navigation packages. The results indicate that the robot accomplishes its objectives while satisfying RT constraints.

We have extended and refined the existing young stellar object (YSO) catalogs for the Orion A molecular cloud, the closest massive star-forming region to Earth. This updated catalog is driven by the large spatial coverage (18.3 deg2, ∼950 pc2), seeing limited resolution (∼0.7″), and sensitivity (Ks < 19 mag) of the ESO-VISTA near-infrared survey of the Orion A cloud (VISION). Combined with archival mid- to far-infrared data, the VISTA data allow for a refined and more robust source selection. We estimate that among previously known protostars and pre-main-sequence stars with disks, source contamination levels (false positives) are at least ∼6.4% and ∼2.3%, respectively, mostly due to background galaxies and nebulosities. We identify 274 new YSO candidates using VISTA/Spitzer based selections within previously analyzed regions, and VISTA/WISE based selections to add sources in the surroundings, beyond previously analyzed regions. The WISE selection method recovers about 59% of the known YSOs in Orion A’s low-mass star-forming part L1641, which shows what can be achieved by the all-sky WISE survey in combination with deep near-infrared data in regions without the influence of massive stars. The new catalog contains 2980 YSOs, which were classified based on the de-reddened mid-infrared spectral index into 188 protostars, 185 flat-spectrum sources, and 2607 pre-main-sequence stars with circumstellar disks. We find a statistically significant difference in the spatial distribution of the three evolutionary classes with respect to regions of high dust column-density, confirming that flat-spectrum sources are at a younger evolutionary phase compared to Class IIs, and are not a sub-sample seen at particular viewing angles.

Reintroduction and stock enhancement of European weatherfish (Misgurnus fossilis L.) in Rhineland-Palatinate and Hesse, Germany
Authors: Schreiber Benjamin , Korte Egbert , Schmidt Thomas , Schulz Ralf
Published: November 2018

A stocking program for the endangered European weatherfish (Misgurnus fossilis L.) was conducted in the German federal states of Rhineland-Palatinate and Hesse, southwest Germany. An initial monitoring enabled to identify local broodstock and to assess habitats regarding their ecological suitability for reintroduction. In a second step, broodstock were caught for artificial propagation and cultured fry were released in previously selected river sectors. Furthermore, reintroduction sectors were biannually monitored to assess stocking success. Within the study period (2014–2016), a total number of approximately 83,500 juveniles were stocked in three river sectors for reintroduction and approximately 85,000 juveniles were stocked in four other river sectors to strengthen existing populations. During the post-release monitoring, 45 individuals were recaptured in two sectors. The documented short-term reintroduction success (i.e. survival of released individuals) indicates appropriateness of the selected stocking strategy. Furthermore, the provided course of action might be transferred to further states or countries and thereby contribute to weatherfish conservation at larger scales.
Metazoan parasite communities of two deep-sea elasmobranchs: the southern lanternshark, Etmopterus granulosus, and the largenose catshark, Apristurus nasutus, in the Southeastern Pacific Ocean
Authors: Espínola-Novelo Juan F. , Escribano Rubén , Oliva Marcelo E.
Published: November 2018

Two deep-sea shark species were obtained as by-catch of the local fishery of the Patagonian toothfish, Dissostichus eleginoides, at depths ranging from 1000 to 2200 m off central and northern Chile. A total of 19 parasite taxa were found in 133 specimens of the southern lanternshark, Etmopterus granulosus, (n = 120) and largenose catshark, Apristurus nasutus, (n = 13). Fourteen taxa (four Monogenea, one Digenea, four Cestoda, one Nematoda, two Copepoda, one Annelida and one Thecostraca) were found in E. granulosus, whereas five taxa (one Monogenea, two Cestoda and two Nematoda) were found in A. nasutus. Representatives of Cestoda showed higher values of prevalence and a greater intensity of infection; this pattern is consistent with reports for elasmobranchs, but the monogenean richness was higher than that previously reported for related deep-sea sharks. Regarding E. granulosus, a positive and significant correlation between host length and abundance was found for six (four ectoparasites, one mesoparasite, and one endoparasite) of the 14 taxa recorded, but prevalence was significantly correlated with host length only for the monogenean Asthenocotyle sp. Although the sample size for A. nasutus was limited, we compared richness, abundance, diversity and evenness at the infracommunity and component community levels. All of these variables were higher for E. granulosus, but at the infracommunity level, abundance was higher for A. nasutus. All the parasite taxa (except two) represent new host and geographical records.
Super-replication price: it can be ok
Authors: Carassus Laurence , Vargiolu Tiziano
Published: November 2018

We consider a discrete time financial model where the support of the conditional law of the risky asset is bounded. For convex options we show that the super-replication problem reduces to the replication one in a Cox-Ross-Rubinstein model whose parameters are the law support boundaries. Thus the super-replication price can be of practical use if this support is not to large. We also make the link with the recent literature on multiple-priors models.

Published: November 2018

We improve the results about the well-posedness of the regularized fractional dispersive equation (1 + Dxα)ut + ux + uux = 0 when 0 < α ≤ 1. When #x03B1; < 1, the existence and uniqueness of vanishing viscosity solution is proved.
Echokardiografie bei akuter Rechtsherzinsuffizienz
Authors: Schäfer Benedikt , Greim Clemens-Alexander
Published: November 2018

Die akute Rechtsherzinsuffizienz wird als Ursache einer kardiopulmonalen Insuffizienz häufig übersehen und kann vital bedrohlich sein. Die verschiedenen Krankheitsbilder, die der Rechtsherzinsuffizienz ätiologisch auf Ebene der Nachlast, Vorlast und Kontraktilität zugrunde liegen, können mittels zielgerichteter Diagnostik abgeklärt werden. Neben klinischen Symptomen ist vor allem die Echokardiografie für die Diagnosestellung relevant.
Sehschärfe, Kontrastempfindlichkeit, Farbensehen: Gedanken zu psychophysischen Untersuchungen in der Neuroophthalmologie
Authors: Heinrich Sven , Hoffmann Michael
Published: November 2018

Trotz aller technischen Fortschritte in der ophthalmologischen Diagnostik spielt die psychophysische Untersuchung der individuellen Sehleistungen weiterhin eine wichtige Rolle. Dies gilt insbesondere für neuroophthalmologische Fragestellungen. Der vorliegende Artikel betrachtet methodische und klinische Aspekte der Untersuchung von Sehschärfe, Kontrastempfindlichkeit und Farbsehvermögen. Im Gegensatz zur Sehschärfe wird die Kontrastempfindlichkeit bislang nur selten untersucht, obgleich ihre Reduktion in vielen Fällen ein sensitiverer Indikator einer Erkrankung ist. Generell haben standardisierte Verfahren, wie sie insbesondere für die Sehschärfeprüfung existieren, den Vorteil der Vergleichbarkeit. Vom Standard abweichende Verfahren können hierbei jedoch unter Umständen die spezifischen, für eine Erkrankung charakteristischen Sehstörungen besser erfassen, sodass deren Anwendung im konkreten Einzelfall gerechtfertigt ist. Dies zeichnet sich auch für die Testung des Farbensehens ab. Bisherige Studien deuten darauf hin, dass die Messung der Farbsättigungsschwelle bei erworbenen Farbsehstörungen eine effiziente und sensitive Alternative zu herkömmlichen Farbsehtests darstellen könnte.
Behandlungssteuerung – eine Herausforderung zwischen Akutmedizin und medizinischer Rehabilitation
Authors: Bagus Peter
Published: November 2018

Wenngleich die Entgiftungsbehandlung bei Alkoholabhängigkeit unstrittig von Seiten der Kostenträger als Aufgabe der Akutmedizin akzeptiert ist, so gilt dies keineswegs uneingeschränkt für die weiteren Behandlungsschritte bei zusätzlich vorliegender Essstörung und weiterer erheblicher psychischer Komorbiditäten. Die Behandlungssteuerung wird zu einer besonderen Aufgabe im Kontext des Behandlungsbedarfes. Der Einbezug der ICF (Internationale Klassifikation der Funktionsfähigkeit, Behinderung und Gesundheit) erweist sich hier als hilfreich. Die vorliegende Arbeit fokussiert schlaglichtartig die Problematik anhand einer Fallskizze. Im konkreten Fall ist schließlich Rehabilitationsfähigkeit ein wichtiges Ergebnis einer an den Leitlinien orientierten mehrmonatigen stationären Krankenhausbehandlung in 2 Fachbereichen.

Published: November 2018

The visible-light-mediated synthesis of trifluoromethylthiolated arenes in the presence of ruthenium-based photocatayst under mild reaction conditions is reported. The trifluoromethylthiolated arenes are obtained using the shelf-stable reagent trifluoromethyl toluenethiosulfonate at room temperature. The reaction proceeds selectively and does not require the presence of any additive. A mechanism is proposed based on the obtained results of EPR as well as luminescence

Asymmetric Total Synthesis and Biological Evaluation of (+)-Cycloclavine
Authors: McCabe Stephanie , Wipf Peter
Published: November 2018

The first total synthesis of natural (+)-cycloclavine uses a catalytic­ asymmetric cyclopropanation of allene, a regiospecific Pd-catalyzed­ enone formation, and two intramolecular Diels–Alder reactions for indole/indoline annulations. The binding properties of natural (+)- and unnatural (–)-cycloclavine on 16 CNS receptors revealed significant stereospecificity and unique binding profiles in comparison to LSD, psilocin, and DMT. Differential 5-HT affinities, as well as novel sigma­-1 receptor properties bode well for potential therapeutic developments of clavine alkaloid scaffolds.

Published: November 2018

Blue-light-mediated cyclopropanation of indoles with aryl(diazo)acetates has been developed. The salient features of this strategy are that it is metal-free, operationally simple and atom-efficient, and that it uses an environmentally friendly energy source. In this protocol, blue light was employed as the sole energy source for the transformation. A variety of cyclopropane-fused indoline compounds was obtained in moderate to excellent yields and high diastereoselectivities under mild conditions.

Published: November 2018

We have examined the influence of an incorporating surfactant on chemical ordering in GaAsN:Bi alloys. Epitaxy with a (2 × 1) reconstruction leads to the formation of GaAsN alloys, while the introduction of a Bi flux induces long-range chemical ordering of the {111} planes of GaAsN:Bi. We propose a mechanism in which Bi enhances the alignment of dimer rows along the [110] direction, facilitating N incorporation beneath surface dimers and Bi incorporation between dimer rows to form alternating N-rich and Bi-rich {111} planes. These findings suggest a route to tailoring the local atomic environment of N and Bi atoms in a wide range of emerging dilute nitride-bismide alloys.
Scalability and wide temperature range operation of spin-orbit torque switching devices using Co/Pt multilayer nanowires
Authors: Jinnai Butsurin , Sato Hideo , Fukami Shunsuke , Ohno Hideo
Published: November 2018

Spin-orbit torque (SOT) switching and retention properties in Co/Pt multilayer nanowire structures with various widths w down to 20 nm and the temperature dependences of the performance in the nanowire device with w = 20 nm are studied. Switching current Isw scales down as w is reduced. The nanowire devices show high thermal stability factor Δ > 100 for all the widths at room temperature. In the 20-nm-wide device, while a magnetization can be switched by current from –50 to 125 °C with a marginal increase in Isw as the temperature decreases, Δ of more than 100 is kept up to 125 °C. These results indicate that SOT-switching devices using Co/Pt multilayers are scalable in nanoscale dimensions and can operate over a wide range of temperatures, offering high potential for a wide variety of applications including automobile and aerospace.
Plasmon excitation and subsequent isomerization dynamics in naphthalene and azulene under fast proton interaction

Published: November 2018

The interaction of fast protons (velocity between 1.41 and 2.4 a.u.) with naphthalene and azulene is investigated as a model of an ion-polycyclic aromatic hydrocarbon interaction system. Production of various intact and fragment ions in coincidence with electron emission, electron transfer to projectile, or both is analyzed. The two targets being isomers, the rather obvious similarity in the fundamental ion-molecule collision energetics is quantitatively verified. The fast isomerization processes of cationic azulene are observed to be influencing its further dissociation channels such as C2H2 and H eliminations. A first ever attempt is presented here wherein single plasmon excitation in conjunction with isomerization dynamics is reported. Evidence from dication evaporation energetics is used to invoke the double plasmon excitation model. A model based on the multiplasmon resonance explains the observed proton velocity dependence of double to single ionization cross sections. Moreover an attempt is made to reinforce the proposition of double plasmon excitation by explaining the observed suppression of neutral H loss from dications as opposed to monocations.

Published: November 2018

We demonstrate a flip-chip device for performing low-temperature acoustoelectric measurements on exfoliated two-dimensional materials. With this device, we study gate-tunable acoustoelectric transport in an exfoliated monolayer graphene device, measuring the voltage created as high-frequency surface acoustic waves dynamically drive the graphene charge carriers, the density of which we simultaneously control with a silicon back-gate. We demonstrate ambipolar dependence of the acoustoelectric signal, as expected from the sign of the graphene charge carriers. We observe a marked reduction in the magnitude of the acoustoelectric signal over a well-defined range of density in the vicinity of charge neutrality, which we attribute to a spatially heterogeneous charge-disorder landscape not directly revealed by conventional transport measurements.
A hybrid electrostatic retarding potential analyzer for the measurement of plasmas at extremely high energy resolution
Authors: Collinson Glyn A. , Chornay Dennis J. , Glocer Alex , Paschalidis Nick , Zesta Eftyhia
Published: November 2018

Many space plasmas (especially electrons generated in planetary ionospheres) exhibit fine-detailed structures that are challenging to fully resolve with the energy resolution of typical space plasma analyzers (10% → 20%). While analyzers with higher resolution have flown, generally this comes at the expense of sensitivity and temporal resolution. We present a new technique for measuring plasmas with extremely high energy resolution through the combination of a top-hat Electrostatic Analyzer (ESA) followed by an internally mounted Retarding Potential Analyzer (RPA). When high resolutions are not required, the RPA is grounded, and the instrument may operate as a typical general-purpose plasma analyzer using its ESA alone. We also describe how such an instrument may use its RPA to remotely vary the geometric factor (sensitivity) of a top hat analyzer, as was performed on the New Horizons Solar Wind at Pluto and MAVEN SupraThermal and Thermal Ion Composition instruments. Finally, we present results from laboratory testing of our prototype, showing that this technique may be used to construct an instrument with 1.6% energy resolution, constant over all energies and angles.
Unsupervised machine learning for detection of phase transitions in off-lattice systems. I. Foundations
Authors: Jadrich R. B. , Lindquist B. A. , Truskett T. M.
Published: November 2018

We demonstrate the utility of an unsupervised machine learning tool for the detection of phase transitions in off-lattice systems. We focus on the application of principal component analysis (PCA) to detect the freezing transitions of two-dimensional hard-disk and three-dimensional hard-sphere systems as well as liquid-gas phase separation in a patchy colloid model. As we demonstrate, PCA autonomously discovers order-parameter-like quantities that report on phase transitions, mitigating the need for a priori construction or identification of a suitable order parameter—thus streamlining the routine analysis of phase behavior. In a companion paper, we further develop the method established here to explore the detection of phase transitions in various model systems controlled by compositional demixing, liquid crystalline ordering, and non-equilibrium active forces.
