Distinct contributions of human posterior parietal and dorsal premotor cortex to reach trajectory planning
Authors: Pilacinski Artur , Lindner Axel
Published: February 2019

Goal-directed hand movements are usually directed straight at the target, e.g. when swatting a fly. Their paths can also become quite complex, when drawing or avoiding obstacles. Studies on movement planning have largely neglected the latter movement type and the question of whether it is the same neural machinery that is planning such complex hand trajectories as well as straight, vector-like movements. Using time-resolved fMRI during delayed response tasks we examined planning activity in human superior parietal lobule (SPL) and dorsal premotor cortex (PMd). We show that the recruitment of both areas in trajectory planning differs significantly: PMd represented both straight and complex hand trajectories while SPL only those that led straight to the target. This suggests that while posterior parietal cortex only provides representations for simple, straight reaches, the complex and computationally demanding reach planning necessarily involves dorsal premotor cortex. Our findings yield new insights into the organization of cerebro-cortical strategies of forming reach trajectory plans.

Current closed‐loop control and field orientation analysis of an induction motor in six‐step operation for railway applications
Authors: Fang Xiaochun , Tian Zhongbei , Li Hua , Yang Zhongping , Lin Fei , Hillmansen Stuart
Published: February 2019

In railway traction drive systems, six‐step operation is widely used for motors in a flux‐weakening region. Traditional vector control algorithms in six‐step operation cannot work effectively due to the limitation of a single degree of freedom. This study analyses the dq current coupling relationship when the voltage amplitude is limited and applies a current closed‐loop control strategy in six‐step operation. This study proposes a proper switching control strategy to achieve a dual‐mode control for induction motors in a full‐speed region. The accuracy of field orientation is affected by changes in motor parameters and plays a key role in current control precision. This study analyses the effect of field orientation error on motor six‐step operation. It is found that the proposed current closed‐loop control strategy can correct the field orientation error and guarantee the motor current to track the reference precisely. A case study of a 5.5 kW experimental platform is presented to validate the control schemes.

We report Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO(3-2) emission in a sample of seven Seyfert/LINER galaxies at the unprecedented spatial resolution of 0.″1 = 4−8 pc. Our aim is to explore the close environment of active galactic nuclei (AGN), and the dynamical structures leading to their fueling, through the morphology and kinematics of the gas inside the sphere of influence of the black hole. The selected galaxies host low-luminosity AGN and have a wide range of activity types (Seyferts 1 to 2, LINERs), and barred or ringed morphologies. The observed maps reveal the existence of circumnuclear disk structures, defined by their morphology and decoupled kinematics, in most of the sample. We call these structures molecular tori, even though they often appear as disks without holes in the center. They have varying orientations along the line of sight, unaligned with the host galaxy orientation. The radius of the tori ranges from 6 to 27 pc, and their mass from 0.7 × 107 to 3.9 × 107 M⊙. The most edge-on orientations of the torus correspond to obscured Seyferts. In only one case (NGC 1365), the AGN is centered on the central gas hole of the torus. On a larger scale, the gas is always piled up in a few resonant rings 100 pc in scale that play the role of a reservoir to fuel the nucleus. In some cases, a trailing spiral is observed inside the ring, providing evidence for feeding processes. More frequently, the torus and the AGN are slightly off-centered with respect to the bar-resonant ring position, implying that the black hole is wandering by a few 10 pc amplitude around the center of mass of the galaxy. Our spatial resolution allows us to measure gas velocities inside the sphere of influence of the central black holes. By fitting the observations with different simulated cubes, varying the torus inclination and the black hole mass, it is possible to estimate the mass of the central black hole, which is in general difficult for such late-type galaxies, with only a pseudo-bulge. In some cases, AGN feedback is revealed through a molecular outflow, which will be studied in detail in a subsequent article.
Impfen in Deutschland – Empfehlungen der STIKO
Authors: Mertens Thomas
Published: February 2019

The epidemiological effect of vaccination is that it primarily reduces the incidence and prevalence of infectious agents and diseases, providing ideal conditions (also from an economic point of view) for prevention. Goal of vaccination is first the individual protection. Other goals may be “herd immunity”, regional repression and global extinction. The STIKO provides recommendations for the implementation of vaccinations and for the implementation of other measures for the specific prevention of communicable diseases and develops criteria for the differentiation of a customary vaccination reaction and damage to health beyond the usual extent of a vaccination reaction. Earlier vaccination recommendations based on “expert opinion” but today are based on the best available evidence. Current STIKO recommendations include vaccination against seasonal influenza, vaccination against HPV, Tdap booster, tetanus PEP, and vaccine management in practice and among migrants. For the success of the vaccination recommendations, it is first and foremost crucial that the medical profession complies with the obligation to inform about vaccination options and needs vis-à-vis patients or guardians.
Verletzungen im Unihockey – Eine Fragebogenerhebung bei Schweizer-Nationalliga-A-Unihockey-Spielern
Authors: Engel Jonas , Kälin Moritz , Rogan Slavko
Published: February 2019

Hintergrund Schnelle Richtungswechsel, Beschleunigungen, Abbrems- und Täuschungsmanöver mit Drehbewegungen führen im Unihockey zu einer erhöhten Verletzungsanfälligkeit. Zum heutigen Zeitpunkt fehlen Daten und Fakten aus der Schweizer Unihockeyliga, die aufzeigen, welche Verletzungen auftreten. Diese Arbeit hatte die Zielsetzung herauszufinden, welche Verletzungen im Schweizer-Nationalliga-A-Unihockey auftreten.

Probanden/Methodik Die vorliegende Arbeit wurde im retrospektiven, nicht experimentellen Design als Fragebogenerhebung durchgeführt. 5 Schweizer-Unihockey-Nationalliga-A-Mannschaften wurden zum Expositionszeitraum von 12 Monaten schriftlich befragt. Die Verletzungsrate beschreibt die Verletzungsanzahl pro 1000 Expositionsstunden. Zur Signifikanzeinschätzung der Resultate wurde der Wilcoxon-Rangsummentest angewendet. Bei allen Testungen wurde das Signifikanzniveau auf p < 0,05 gesetzt.

Ergebnisse In einem Kalenderjahr erlitten N = 71 aller Spieler (N = 101) im Schnitt 1,14 Verletzungen (± 1,05). Die Verletzungsrate betrug im präsentierten Datensatz 2,01. Die Verletzungsrate ist im Wettkampf 2-mal höher als im Training (Rate-Ratio (RR) = 2,04). Von den beschriebenen Verletzungslokalisationen sind das Sprunggelenk, der Oberschenkel, das Knie und der Rücken betroffen. Es zeigten sich am häufigsten Verstauchungen, Muskelverletzungen und Entzündungen. Muskelverletzungen traten dabei fast ausschließlich am Oberschenkel auf. Verstauchungen ereigneten sich meistens am Sprunggelenk.

Schlussfolgerung Die vorliegende Arbeit bestätigt die Hypothese, dass im Unihockey die Verletzungsanfälligkeit während des Wettkampfs im Vergleich zum Training deutlich höher liegt. Es kann angenommen werden, dass Spieler, bei denen die sportliche Aktivität deutliche Müdigkeit und emotionalen Stress auslöst, verletzungsanfälliger sind. Weiterführende Studien sollten verschiedene Präventionsmaßnahmen überprüfen und einen Vergleich zur geschlechterspezifischen Verletzungsanfälligkeit herstellen.
Verzicht auf Einleitung oder Abbruch einer Reanimation in der Präklinik
Authors: Sefrin Peter , Kerner Thoralf , Dörges Volker
Published: February 2019

Nicht selten wird der Notarzt mit Patienten mit einem Herz-Kreislauf-Stillstand konfrontiert, wobei sich im Einzelfall die Frage stellt, ob eine kardiopulmonale Reanimation nicht begonnen oder eine bereits begonnene Reanimation beendet werden soll. Hierzu gibt es Leitlinien und Stellungnahmen des ERC und der Bundesärztekammer sowie Hinweise in der Literatur. Nachdem es für diese Frage aber keine verbindlichen und allgemeingültigen Kriterien gibt, ist in diese individuelle Entscheidung neben der Anamnese die jeweilige aktuelle Situation einzubeziehen, und diese kann nicht aufgrund starrer Zeitvorgaben getroffen werden. Neben generellen Prognosefaktoren wird auf die Besonderheiten der Reanimation bei Polytrauma, Hypothermie, Lungenarterienembolie und Suizid eingegangen. Eine besondere Patientengruppe stellen ältere Patienten dar, bei denen manchmal eine sogenannte „Schein“-Reanimation durchgeführt wird. In die Entscheidung zur Durchführung oder zum Abbruch einer Reanimation ist auch der Patientenwille miteinzubeziehen, sofern dieser vor Ort zweifelsfrei erkennbar ist. Gründe für das Unterlassen einer Reanimation im präklinischen Bereich werden zusammenfassend dargestellt.
Anwendungssoftware zur Förderung der Adhärenz in der Arzneimitteltherapie
Authors: Njeri Jackline Wariara
Published: February 2019

Der demografische Wandel und die Fortschritte der modernen Medizin stellen das Gesundheitssystem vor neue Herausforderungen. Mit zunehmendem Alter steigt die Multimorbidität sowie die Anzahl an chronischen Erkrankungen. Eine der größten Herausforderungen für chronisch Kranke ist die Polypharmazie, gekoppelt mit der strikten Einhaltung des Therapieschemas. Das Problem der Non-Adhärenz in der Arzneimitteltherapie, das schon sehr lange bekannt ist, wird immer präsenter. Parallel hat sich die Smartphone-Technologie rasant entwickelt mit vielversprechenden zukunftsweisenden digitalen Lösungen. In Anbetracht dieser beiden Aspekte ist das Ziel der vorliegenden Untersuchung, herauszufinden, ob die moderne Technologie in Form einer Medikamenten-Erinnerungs-App die unbeabsichtigte Non-Adhärenz in der Arzneimitteltherapie positiv beeinflussen kann. Gleichzeitig muss überprüft werden, ob ein Therapieerfolg sicherzustellen ist. Um die Forschungsfrage adäquat zu beantworten, ist ein standardisiertes Non-Adhärenz-Screening und eine Blutdruckanalyse durchgeführt worden. Die Teilnehmer wurden nach bestimmten Kriterien ausgesucht und nutzten nach einem Training die Medikamenten-App „MedPlaner“ als Gedächtnishilfe zur Medikamenten-Einnahme. Die Intervention erwies sich als vorteilhaft, da die Adhärenz-Rate innerhalb von 3 Wochen in der Interventionsgruppe anstieg und eine Besserung der Blutdruckwerte zu beobachten war. Insgesamt lässt sich also feststellen, dass die Nutzung einer Medikamenten-App als Gedächtnishelfer durchaus einen positiven Einfluss auf die Non-Adhärenz in der Arzneimitteltherapie nimmt.
Reduced Gene Expression of Peroxisome Proliferator-Activated Receptor Gamma Coactivator-1α in Whole Blood in Euthyroid Patients One Year After Hemithyroidectomy for Benign Euthyroid Goiter
Authors: Kristensen Tina , Pedersen Palle , Larsen Jacob , Feldthusen Anne-Dorthe , Jelstrup Søren , Ellervik Christina
Published: February 2019

We have previously reported decreased thyroid function within the laboratory reference range and changes in mitochondrial function after hemithyroidectomy. Peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) and coactivator-1β (PGC-1β) are key regulators of mitochondrial biogenesis and function. The aim was to examine the influence of hemithyroidectomy on the longitudinal change in mRNA expression of these genes. In addition, we measured longitudinal changes in mRNA expressions of the mitochoncrial-related genes nuclear factor erythroid-derived 2-like 2 (NFE2L2), mitochondrial transcription factor A (TFAM), and sodium dismutase 2 (SOD2). Twenty-eight patients were examined before and 1, 3, 6, and 12 months after hemithyroidectomy for benign euthyroid goiter. Thyroid stimulating hormone (TSH) and thyroid hormones were measured, and whole blood gene expression of PGC-1α, PGC-1β, NFE2L2, TFAM, and SOD2 was examined by reverse transcription quantitative Polymerase Chain Reaction. We used mixed effect regression models to investigate changes in gene expression with time. Averaged over all follow-up visits, TSH increased (p=0.001), tT3 declined (p=0.01), and fT4/tT3 ratio increased (p=0.03) over one-year follow-up, but fT4 remained unchanged. Averaged over all follow-up visits, whole blood PGC-1α levels (p<0.001) and SOD2 (p=0.009) levels declined, but PGC-1β, TFAM, and NFE2L2 did not change over one-year follow-up. The study demonstrates significant downregulation of whole blood PGC-1α and SOD2 gene expressions in hemithyroidectomized patients with a concomitant increase in TSH concentration within the reference range. Thus, hemithyroidectomized patients may likely have impaired mitochondrial function.
Zusammenhang von Obstipation und Dialysatauslaufstörungen bei Peritonealdialysepatienten
Authors: Nipshagen Sabine
Published: February 2019

Zur Erstellung einer nephrologischen Pflegeplanung braucht es wissenschaftliche Daten. Dass eine Obstipation Auslaufstörungen bei der Peritonealdialyse verursachen kann, beruht auf Erfahrungswerten. Mit dieser Untersuchung soll erfasst werden, ob eine Obstipation Auswirkungen auf Dialysatauslaufstörungen hat. Für diese prospektive Studie wurde an 23 Patienten aus 3 Dialysezentren in Hessen ein Fragebogen verteilt. Dieser basiert auf der Grundlage der Rom-III-Kriterien zur Erfassung der chronischen Obstipation unter Zuhilfenahme der Bristol-Stuhlformen-Skala. Auslaufstörungen wurden anhand der Dialyseprotokolle erfasst. In die Auswertung wurden 19 Fragebögen einbezogen. Ein Zusammenhang zwischen Obstipation und Auslaufstörungen konnte mit dieser Studie nicht nachgewiesen werden. Die Obstipationsinzidenz in dieser Gruppe liegt bei 31 % und damit deutlich höher als in der Gesamtbevölkerung Deutschlands. 68 % der Teilnehmer weisen Obstipationssymptome auf. Besonders oft gaben die Teilnehmer ein Gefühl der inkompletten Entleerung an. Eine Laxanziengabe bewirkte nur bei einem Teilnehmer eine Symptomfreiheit. Da Peritonealdialysepatienten überdurchschnittlich häufig eine Obstipation und Obstipationssymptome aufweisen, ist eine Berücksichtigung dieser Problematik in der nephrologischen Pflegeplanung zu empfehlen. Wünschenswert sind weitere Erhebungen in einem größeren Rahmen, um den Zusammenhang zwischen Obstipation und Auslaufstörungen darzustellen.
Individuelle Schulung von Hämodialysepatienten
Authors: Dreyer Antje
Published: February 2019

Adhärenz verringert Komplikationen im Krankheitsverlauf und erhöht die Lebensqualität und -erwartung von Patienten. Die vorliegende Arbeit überprüft, ob sich die Adhärenz bei Menschen mit Chronic Kidney Disease (CKD) durch eine 2-teilige Schulung zur Nieren- und Dialysefunktion steigern lässt. Nach den Prinzipien der Salutogenese sowie einem ressourcen-orientierten Verständnis von Adhärenz wurde vermutet, dass die Schulungen die Betroffenen dazu ermutigen, sich selbstbestimmt und eigenverantwortlich an der Therapie zu beteiligen. Dazu wurde in dem Schulungsprogramm auf leichte Verständlichkeit der Sachinformationen, gehirngerechtes Lernen und individuelle Zielsetzung fokussiert. Es zeigte sich, dass die Schulung den Menschen mit CKD dabei half, niedrigere Serum-Phosphat-Werte und verringerte Ultrafiltrationswerte zu erreichen. Die Auswertung einer zusätzlichen Befragung der Patienten ergab, dass der Grund hierfür v. a. ein gesteigertes Wissen über Nieren- und Dialysefunktion war. Es wird diskutiert, unter welchen Bedingungen eine derartige Intervention in der Praxis sinnvoll implementiert werden kann. Die Ergebnisse werden im Kontext der nephrologischen Pflege gesehen.

Rhinoplasty is universally considered as the most demanding procedure in facial plastic surgery. Secondary rhinoplasty is its crown jewel, even more complex, and likewise highly fascinating. The evolution of thought and practice in rhinoplasty in the last decades has been quick and steady, progressively acknowledging the importance of maintaining structure in primary rhinoplasty and rebuilding structure in secondary procedures. No longer is the paradigm to achieve a small, thin, and pointy nose, but rather a well-proportioned nose which looks natural, albeit elegant and breathing well. Rib is an essential tool in many secondary procedures, and thus some important concepts have to be well understood and some finesse points mastered. This will provide an elegant reconstruction, identical if possible, or at least not far apart, to what could be achieved by a well-executed primary rhinoplasty, while avoiding the feared luck of a bulky nose stuffed with grafts. These guiding concepts and specific nuances regarding harvesting rib and working with it are the scope and contents of this article.
Comparison of structural and optical properties of blue emitting In0.15Ga0.85N/GaN multi-quantum-well layers grown on sapphire and silicon substrates

Six periods of 2-nm-thick In0.15Ga0.85N/13-nm-thick GaN blue emitting multi-quantum-well (MQW) layers are grown on sapphire (Al2O3) and silicon (Si) substrates. X-ray diffraction, Raman spectroscopy, atomic force microscopy, temperature-dependent photoluminescence (PL), Micro-PL, and time-resolved PL are used to compare the structural and optical properties, and the carrier dynamics of the blue emitting active layers grown on Al2O3 and Si substrates. Indium clustering in the MQW layers is observed to be more pronounced on Al2O3 than those on Si as revealed through investigating band-filling effects of emission centers, S-shaped peak emission energy shifts with increasing temperature, and PL intensity-peak energy spatial nonuniformity correlations. The smaller indium clustering effects in MQW on Si are attributed to the residual tensile strain in the GaN buffer layer, which decreases the compressive strain and thus the piezoelectric polarization field in the InGaN quantum wells. Despite a 30% thinner total epitaxial thickness of 3.3 µm, MQW on Si exhibits a higher IQE than those on Al2O3 in terms of internal quantum efficiency (IQE) at temperatures below 250 K, and a similar IQE at 300 K (30% vs 33%). These results show that growth of blue emitting MQW layers on Si is a promising approach compared to those conventionally grown on Al2O3.
Efficient implementation of the non-Dyson third-order algebraic diagrammatic construction approximation for the electron propagator for closed- and open-shell molecules

Published: February 2019

A novel efficient implementation of the non-Dyson algebraic diagrammatic construction (ADC) scheme of the (N − 1)-part of the electron propagator up to third order of perturbation theory is presented. Due to the underlying spin-orbital formulation, for the first time, the computation of ionization potentials of open-shell radicals is thus possible via non-Dyson ADC schemes. Thorough evaluation of the accuracy, applicability, and capabilities of the new method reveals a mean error of 0.15 eV for closed- as well as open-shell atoms and molecules.

Two independent methods, namely, Binary-encounter Bethe (BEB) and complex scattering potential-ionization contribution (CSP-ic) methods, are employed to calculate the total ionization cross section (Qion) for cyclic organic molecules from ionization threshold to 5 keV for which there is a paucity of data in the literature. The Qion calculated with the (BEB/ωB97X) combination is found to give good agreement with the experimental results, the CSP-ic method, and the Qion calculated from Irikura orbital energies. The Qion for most of the targets are calculated for the first time over such a wide energy range. Hence, to check the consistency and reliability of the present data, we have also computed the static polarizability for all the targets and the variation of maximum ionization cross section (Qion,max) with polarizability is studied. A linear relationship is observed between these quantities indicating the consistency and reliability of the present Qion data. The targets studied are important for industrial applications, radiation biology, and astrophysics.

Reliable and accurate knowledge of the physical properties of elementary point defects is crucial for predictive modeling of the evolution of radiation damage in materials employed in harsh conditions. We have applied positron annihilation spectroscopy to directly detect mono-vacancy defects created in tungsten through particle irradiation at cryogenic temperatures, as well as their recovery kinetics. We find that efficient self-healing of the primary damage takes place through Frenkel pair recombination already at 35 K, in line with an upper bound of 0.1 eV for the migration barrier of self-interstitials. Further self-interstitial migration is observed above 50 K with activation energies in the range of 0.12–0.42 eV through the release of the self-interstitial atoms from impurities and structural defects and following recombination with mono-vacancies. Mono-vacancy migration is activated at around 550 K with a migration barrier of EmV=1.85±0.05 eV.
Quantum dynamics and spectroscopy of dihalogens in solid matrices. I. Efficient simulation of the photodynamics of the embedded I2Kr18 cluster using the G-MCTDH method
Authors: Picconi David , Cina Jeffrey A. , Burghardt Irene
Published: February 2019

The molecular dynamics following the electronic BΠu30+⟵XΣg+1 photoexcitation of the iodine molecule embedded in solid krypton are studied quantum mechanically using the Gaussian variant of the multiconfigurational time-dependent Hartree method (G-MCTDH). The accuracy of the Gaussian wave packet approximation is validated against numerically exact MCTDH simulations for a fully anharmonic seven-dimensional model of the I2Kr18 cluster in a crystal Kr cage. The linear absorption spectrum, time-evolving vibrational probability densities, and I2 energy expectation value are accurately reproduced by the numerically efficient G-MCTDH approach. The reduced density matrix of the chromophore is analyzed in the coordinate, Wigner and energy representations, so as to obtain a multifaceted dynamical view of the guest-host interactions. Vibrational coherences extending over the bond distance range 2.7 Å < RI–I < 4.0 Å are found to survive for several vibrational periods, despite extensive dissipation. The present results prepare the ground for the simulation of time-resolved coherent Raman spectroscopy of the I2-krypton system addressed in Paper II.

Published: February 2019

The WiFi technology has become a world-wide everyday service, and the accompanying electromagnetic pollution has attracted more and more attentions. This paper presents a transparent and flexible broadband metamaterial absorber (MMA) covering the whole WiFi waveband. The transparent and conducting material Indium Tin Oxide (ITO) was used for both the frequency select surface and the backplane ground layer, and polydimethylsiloxane (PDMS) was used as the dielectric layer for the microwave MMA. The absorber featured >80% absorption covering a wide frequency range of (2.2-5.85) GHz, which includes all the frequency bands of WiFi signal. The absorber was insensitive to the polarization angles and dropped little for incident angles less than 30°. Signal shielding experiments in 2.4 GHz and 5 GHz were carried out to demonstrate the application potential of the absorber. With additional advantages of optical transparency and mechanical flexibility, the broadband MMA can be useful in WiFi related applications in the future.

Authors: Clark Phillip
Published: February 2019

Haematology of Australian Mammals is a valuable guide to collecting and analysing the blood of Australian mammals for haematological studies and diagnosis and monitoring of disease.

It outlines general principles for selecting sites for blood collection and for handling and analysing samples to achieve quality results. Chapters then describe the morphology and function of haematological cells, with reference to the known characteristics of Australian mammals in health and the changes that may be encountered in response to common diseases. Haemoparasites that have been encountered in Australian mammals are discussed next, along with comments on their pathogenicity. Lastly, haematological values from previously published studies are compiled into species-specific tables, providing a convenient reference to compare to the results of clinical cases.

Written descriptions and colour photomicrographs of haematological cells from more than 100 species aid the identification of cells and the detection of abnormalities. Information is provided throughout for representative species from all the major groups of native Australian mammals including monotremes, polyprotodont marsupials, diprotodont marsupials, rats and mice, bats and marine mammals.
Herons, Egrets and Bitterns
Authors: McKilligan Neil
Published: February 2019

This is the first book to deal exclusively with the Australian members of the Family Ardeidae (herons, egrets and bitterns). It gives a comprehensive, easy-to-read account of their origins, classification and biology, and explains the features that distinguish them from other birds.
The book devotes a major chapter to the 14 Australian species, covering their distribution and movements, feeding, breeding, population dynamics and conservation. Some of Australia’s herons have become very scarce in the southern half of the continent and are at risk of national or local extinction. In northern Australia heron habitats and resources are largely pristine and consequently this region accommodates large numbers of certain species.
A final chapter on population and conservation provides a useful summary of the present status of the Australian herons, some of whom are thriving and others who are in a very precarious position.
