Published: October 2019

AbstractWe report on the magnetism of charge-stripe ordered La2NiO4.11±0.01 by neutron scattering and μSR. On going towards zero energy transfer there is an observed wave vector offset in the centring of the magnetic excitations and magnetic Bragg reflections, meaning the excitations cannot be described as Goldstone modes of the magnetic order. Weak transverse field μSR measurements determine the magnetically order volume fraction is 87% from the two stripe twins, and the temperature evolution of the magnetic excitations is consistent with the low energy excitations coming from the magnetically ordered volume of the material. We will discuss how these results contrast with the proposed origin of a similar wave vector offset recently observed in a La-based cuprate, and possible origins of this effect in La2NiO4.11.

Published: October 2019

AbstractCancer cell lines (CCLs) have been widely used to study of cancer. Recent studies have called into question the reliability of data collected on CCLs. Hence, we set out to determine CCLs that tend to be overly sensitive or resistant to a majority of drugs utilizing a nonlinear mixed-effects (NLME) modeling framework. Using drug response data collected in the Cancer Cell Line Encyclopedia (CCLE) and the Genomics of Drug Sensitivity in Cancer (GDSC), we determined the optimal functional form for each drug. Then, a NLME model was fit to the drug response data, with the estimated random effects used to determine sensitive or resistant CCLs. Out of the roughly 500 CCLs studies from the CCLE, we found 17 cell lines to be overly sensitive or resistant to the studied drugs. In the GDSC, we found 15 out of the 990 CCLs to be excessively sensitive or resistant. These results can inform researchers in the selection of CCLs to include in drug studies. Additionally, this study illustrates the need for assessing the dose-response functional form and the use of NLME models to achieve more stable estimates of drug response parameters.

AbstractAn assessment was carried out of the anthropogenic enrichment of the chemical composition of the bottom sediments of water bodies situated in an area with an urban and industrial character (63.7% of the total area). The endorheic catchments of the water bodies studied are lithologically uniform with sandy formations accounting for more than 90% of the surface area. On the basis of geoaccumulation index values, it was found that the bottom sediments of the water bodies studied were contaminated with the following elements: Cd, Zn, S, As, Pb, Sr, Co, Cr, Cu, Ba, Ni, V, Be, in degrees ranging from moderate to extreme, with lower contamination (or absence of contamination) with the same elements being found in the formations present in the vicinity and in the substrate of the basins of water bodies. It was found that one consequence of the fact that these water bodies are located in urban and industrial areas is that there is anthropogenic enrichment of the chemical composition of bottom sediments with certain basic components (organic matter, Mn, Ca and P compounds) and trace elements: Cd, Zn, Pb, Sb, As, Cu and Co, Br, Ni, S, Be, Cs, Sr, V, Cr, Sc, Ba, U, Ce, Eu and Th, with virtually no enrichment of sediments with the other basic and trace components analysed (La, Rb, K2O, Nd, Sm, Na2O, Hf, SiO2, Zr).

Published: October 2019

AbstractInfants are slower to disengage from faces than non-face patterns when distracted by novel competing stimuli. While this perceptual predilection for faces is well documented, its universality and mechanisms in relation to other aspects of attention are poorly understood. We analysed attention disengagement times for faces and non-face patterns in a large sample of 6-to 9-month-old infants (N = 637), pooled from eye tracking studies in socioculturally diverse settings (Finland, Malawi, South Africa). Disengagement times were classified into distinct groups of quick and delayed/censored responses by unsupervised clustering. Delayed disengagement was frequent for faces (52.1% of trials), but almost negligible for patterns (3.9% of trials) in all populations. The magnitude of this attentional bias varied by individuals, whereas the impact of situational factors and facial expression was small. Individual variations in disengagement from faces were moderately stable within testing sessions and independent from variations in disengagement times for patterns. These results point to a fundamental dissociation of face and pattern processing in infants and demonstrate that the bias for faces can be robust against distractors and habituation. The results raise the possibility that attention to faces varies as an independent, early-emerging social trait in populations.

AbstractThe high-pressure and high-temperature structural and chemical stability of ruthenium has been investigated via synchrotron X-ray diffraction using a resistively heated diamond anvil cell. In the present experiment, ruthenium remains stable in the hcp phase up to 150 GPa and 960 K. The thermal equation of state has been determined based upon the data collected following four different isotherms. A quasi-hydrostatic equation of state at ambient temperature has also been characterized up to 150 GPa. The measured equation of state and structural parameters have been compared to the results ofab initiosimulations performed with several exchange-correlation functionals. The agreement between theory and experiments is generally quite good. Phonon calculations were also carried out to show that hcp ruthenium is not only structurally but also dynamically stable up to extreme pressures. These calculations also allow the pressure dependence of the Raman-activeE2gmode and the silentB1gmode of Ru to be determined.

AbstractLeisure activity is one of key ingredients for individual happiness and life satisfaction. Enjoying leisure activity with one’s partner can increase marital satisfaction. This study aimed to identify the neural basis of making decisions on participation in a leisure activity with one’s romantic partner as well as the relationship between leisure activity and satisfaction with life. Thirty-seven soon-to-be married heterosexual couples were participated in functional MRI while deciding participation in specific leisure activities in the individual, partner, with-friend, and with-partner conditions. We constructed analysis of variance models and investigated couple characteristics such as personality similarity, leisure activity matching rate, and spatial similarity in the bilateral frontoparietal network. The results showed decreased activity in the bilateral hippocampus during the task in the with-partner condition. Individual leisure activity was correlated with quality of life in males, whereas participation in leisure activity might require more cognitive loading on the dorsolateral prefrontal cortex in females. The leisure activity matching rate was correlated with courtship period, personality similarity, and spatial similarity of the right frontoparietal network during the task. These findings suggest that although there are different activation pattern in making decisions on leisure activity between romantic couples, spatial similarity of the partner’s social brain networks may be a marker that predicts how well the couple enjoys leisure activity together. In addition, our couples’ data analysis provides a scientific basis for the saying that romantic couples become more similar the longer they are together.

Published: October 2019

This work reports the first of its kind custom implantable cathodic voltage controlled electrical stimulator (iCVCES) for use with implanted orthopaedic devices. The iCVCES allows researchers to study DC cathodic voltage controlled electrical stimulation (CVCES) in vivo with no percutaneous leads. The iCVCES is a microcontroller‐based potentiostat circuit with wireless (bluetooth) communication that controls the DC cathodic stimulation and monitors the environment around the implant. Comprising a single PCB with a coin cell battery, the device is able to hold a constant voltage as large as −1.8 V in a dynamic impedance environment. In vitro tests demonstrate functionality comparable to bench‐top systems, and in vivo tests demonstrate operation in live rats, for up to 8 days, with the ability to provide constant stimulation with a maximum variation of 2 mV.

Published: October 2019

Highly c‐axis‐oriented scandium‐doped aluminium nitride films (ScAlN) were prepared on platinum substrates by DC magnetron sputtering. The effect of sputtering power on the crystal quality and piezoelectric properties of ScAlN thin film was investigated. The test results show that the piezoelectric properties of the ScAlN film first strengthen and then weaken with the increase of sputtering power, and the optimal piezoelectric properties are obtained under the condition of 180 W. Furthermore, a surface acoustic wave (SAW) resonator with an interdigital transducer width of 500 nm was fabricated by electron beam lithography. The SAW device exhibits a resonant frequency of 1.887 GHz and a quality factor (Q) of 170.8.

Authors: Srinivasan Revathy , Habiba Hyder Ali Umma 
Published: October 2019

This study is targeted towards designing and analysing the X and Ku bands receiving antenna using the Code Blocks software and Advanced Design System simulation tool for energy harvesting in order to satisfy the energy needs of autonomous wireless sensors on board of geostationary satellite for structural health monitoring of the satellite panels, where weight, cost, size and efficiency are the principal space antenna parameters accounted. The energy harvester generally consists of receiving antenna, which harvests and scavenges the circumambient electromagnetic field and inputs the rectifier in order to power the sensors. In this study, a compact, wideband semi‐ellipse patch antenna backed with defected ground structure is presented. The antenna compactness (186.8 mm3) is obtained by truncating the elliptical patch to form a semi‐ellipse patch without compromising the band of interest which reduces from launching weight and cost. The proposed antenna covers X and Ku bands for voltage standing wave ratio ≤2 with a maximum return loss of 28.75 dB, the efficiency of 95%, the gain of 9.6 dBi and directivity of 14 dBi, which makes the proposed antenna compatible to use with the rectifier in order to satisfy the energy needs of wireless sensors.

Published: October 2019

ZusammenfassungDie Darmtuberkulose ist eine extrapulmonale Manifestation einer Infektion mit Mykobakterien des Tuberkulosekomplexes. Sie ist in den Industrieländern äußerst selten geworden, präsentiert sich mit einer sehr heterogenen, unspezifischen Klinik und ist schwer zu diagnostizieren. Anders als bei der pulmonalen Tuberkulose besitzen die wichtigsten diagnostischen Methoden wie der Nachweis säurefester Stäbchen in der Ziehl-Neelsen-Färbung, der Genomnachweis mittels PCR-Untersuchung und die kulturelle Anzüchtung der Bakterien eine geringe Sensitivität. Wir präsentieren hier die Fälle von drei Patienten/-innen, bei denen wir eine Darmtuberkulose diagnostizierten und erfolgreich behandelten. An die Fallberichte anschließend stellen wir eine Literaturübersicht vor, die die Fallstricke der Darmtuberkulosediagnostik und -therapie beleuchtet.
Tinea pedum und verspätet erkannte Zehengangrän bei peripherer arterieller Verschlusskrankheit

Published: October 2019

ZusammenfassungEin Patient wurde unter der Diagnose einer Tinea pedum durch Trichophyton rubrum von einem Dermatologen fachgerecht topisch antimykotisch behandelt. Bei Therapieresistenz und Befundverschlechterung erfolgte eine Umstellung der Lokaltherapie, jedoch keine weitere Diagnostik bez. ätiologischer und Risiko-Faktoren. Eine Vorstellung bei einer chirurgischen Praxis führte zur Diagnose einer umschriebenen Nekrose der 3. Zehe rechts bei bekannter peripherer arterieller Verschlusskrankheit und Immunsuppression mit nachfolgender Zehenamputation und kompliziertem Wundheilungsverlauf. Nach Facharztstandard lag ein Befunderhebungsfehler vor, der rechtlich zu einer Beweislastumkehr führt, sodass die Gesundheitsschädigung in Form des Voranschreitens einer Weichteil- und Knocheninfektion bei umschriebener Nekrose der 3. Zehe rechts mit Amputation dem Arzt zuzurechnen war.Therapieresistente Fußmykosen und infizierte Fußläsionen erfordern unverzüglich intensive Behandlungsmaßnahmen und eine Fahndung nach Risikofaktoren wie eine gefäßdiagnostische Kontrolle.
Was verursacht Prostatakrebs? – Subjektive Krankheitsursachen von Patienten mit Prostatakarzinom
Authors: Goethe Veronika Elisabeth , Dinkel Andreas , Schulwitz Helga , Nöhreiter Alexandra , Gschwend Jürgen Erich , Herkommer Kathleen 
Published: October 2019

Zusammenfassung
Hintergrund Die durch ein Prostatakarzinom (PCa) verursachte psychosoziale Belastung kann bei Patienten noch Jahre nach erfolgter Therapie persistieren. Ein möglicher Faktor ist dabei die subjektiv wahrgenommene Krankheitsursache, die das Belastungserleben, die Therapie und das weitere Präventivverhalten maßgeblich beeinflussen kann. Ziel der Studie war deswegen, von Patienten geäußerte subjektive Gründe für das PCa zu erfassen und assoziierte Faktoren zu untersuchen.
Material und Methoden Eingeschlossen wurden an PCa erkrankte Patienten aus dem nationalen Forschungsprojekt „Familiäres Prostatakarzinom“. Im Rahmen der jährlichen Nachbefragung, die postalisch erfolgt, wurde den Patienten eine Frage zu den subjektiv wahrgenommenen Krankheitsursachen für ihr Prostatakarzinom gestellt. Die Antworten wurden 18 möglichen Kategorien zugeordnet. Zudem wurde der Zusammenhang der subjektiv wahrgenommenen Krankheitsursache mit Zweittumoren, einer positiven Familienanamnese für Tumorerkrankungen und soziodemografischen Faktoren untersucht.
Ergebnisse Von den 9 047 befragten Männern machten 4 054 (44,8 %) Angaben zu den subjektiv wahrgenommenen Ursachen für ihr PCa. Die mittlere Zeit seit Diagnose lag bei 10,1 Jahren bei einem mittleren Alter bei Diagnose von 63,1 Jahren. Die häufigsten Antworten waren „Weiß nicht.“ (31,8 %), Genetik (30,1 %) und Stress (18,5 %). Mit 2,5 % wurde das Alter, der wichtigste Risikofaktor für PCa, nur selten genannt. Neben diesen Antworten wurden auch ungewöhnliche nicht evidenzbasierte Gründe angegeben. Männer mit einer positiven Familienanamnese für PCa nannten gegenüber sporadischen Fällen etwa 4-mal häufiger Genetik als Ursache für ihre Erkrankung. Dieser Anteil nahm mit steigender Anzahl an von PCa betroffenen Familienmitgliedern weiter zu. Männer, die bei Diagnose 65 Jahre oder jünger waren, gaben etwa doppelt so häufig Stress als den Auslöser ihres PCa an als Männer, die bei Diagnose älter als 65 Jahre waren.
Schlussfolgerung Die meisten befragten Männer gaben nicht evidenzbasierte Gründe als ursächlich für ihr Prostatakarzinom an. Hier mangelt es offensichtlich noch an Aufklärung, sodass Vorsorgeprogramme gezielt und öffentlichkeitswirksam auf die evidenzbasierten Ursachen eingehen sollten. Aufgrund der Bedeutung der subjektiven Krankheitstheorie für das Belastungserleben und die weitere Behandlung sollte die subjektive Krankheitsursache des Patienten vom behandelnden Urologen erhoben und berücksichtigt werden.
Outside interference or Hong Kong embracing its unique identity? The Chinese Universities Shakespeare Festival
Authors: Olive Sarah 
Published: October 2019

AbstractOngoing clashes between Hong Kong citizens and its government have foregrounded questions about outside interference in Hong Kong’s politics (largely from the government and media of the People’s Public of China), as well as debate about what institutions in Hong Kong are neo-colonial, heavily inflected with nostalgia for British colonialism, or in the process of being ‘colonised’ by the People’s Republic of China. This article looks at Shakespeare in Hong Kong (and, to some extent, greater Chinese) theatre and education as one of those contested institutions, using the particular case of the now-defunct Chinese Universities Shakespeare Festival. The author probes their initial, surface impression of the festival as a simple outpouring of colonial sentiment and impulse, using its sizeable archives to realise a reading of the institution that highlights the complexities of international and intra-regional politics, culture and identity in Hong Kong and greater China. It builds on the Hong Kong literary critic Michael Ingham’s call for attention to Hong Kong’s quest—sometimes overt (as in the demonstrations of 2019), sometimes implicit (in the body of literature Ingham explores in his cultural and literary history)—for a unique, post-colonial identity that is inspired—but, critically, not confined—by its Chinese and British histories. The article briefly outlines the origins and set-up of the festival before juxtaposing the dominance of English language and culture in it with the opportunities it presents (seized by several teams) for intra-regional cooperation, competition and sharing diverse, greater Chinese cultures. The article offers a model for critically appraising other institutions and cultural products in Hong Kong in ways that resist easy (but false) binaries of British or Chinese, colonial or indigenous.
Generation of parabolic laser pulses in short fibre amplifiers

Published: October 2019

Abstract
The laser pulse evolution in a normal-dispersion fibre amplifier is studied. The cases of ideal spectrum-homogeneous and transform-limited amplification are considered. It is shown that the envelope transformation of the input pulse to a parabolic form is possible not only for spectrally-flat amplification, but also for transform-limited one. In the latter case, an important parameter is the optimal amplifier length. The results demonstrate that, in the case of a sufficiently wide amplification spectrum, it is always possible to find the optimal amplifier length, after passing through which the output pulse envelope is close to a parabola.

Published: October 2019

Significance
Silk polymorphism is used to generate composite materials that can wrinkle reversibly and in complex patterns. This is achieved by leveraging and controlling the ability of structural proteins to change their conformation and their stimulus-responsive behavior to offer a different approach to micro/nanopatterning of dynamic, multifunctional biocompatible interfaces. The results show the ability to reshape protein films on the nano- and microscale on demand and generate functional protein surfaces with tunable topography opening possibilities in programmable biomaterial-based interfaces.

Significance
The spread of multidrug-resistant infections demands antibiotic development. Although new antibiotics targeting gram-positive bacteria have been developed, it has been more than 50 y since a new class of antibiotics targeting gram-negative bacteria has been approved for clinical use. The strong outer membrane permeability barrier makes it difficult for compounds to reach intracellular targets, contributing greatly to the lack of new antibiotics targeting this class of microbes. Here, we describe a compound, MRL-494, that inhibits the assembly of proteins into the outer membrane by targeting an essential member of β-barrel assembly machine. This compound appears to act at the cell surface, avoiding both the outer membrane permeability barrier and the action of multidrug-resistance efflux pumps.
Distinct Laminar Requirements for NMDA Receptors in Experience-Dependent Visual Cortical Plasticity

Published: October 2019

Abstract
Primary visual cortex (V1) is the locus of numerous forms of experience-dependent plasticity. Restricting visual stimulation to one eye at a time has revealed that many such forms of plasticity are eye-specific, indicating that synaptic modification occurs prior to binocular integration of thalamocortical inputs. A common feature of these forms of plasticity is the requirement for NMDA receptor (NMDAR) activation in V1. We therefore hypothesized that NMDARs in cortical layer 4 (L4), which receives the densest thalamocortical input, would be necessary for all forms of NMDAR-dependent and input-specific V1 plasticity. We tested this hypothesis in awake mice using a genetic approach to selectively delete NMDARs from L4 principal cells. We found, unexpectedly, that both stimulus-selective response potentiation and potentiation of open-eye responses following monocular deprivation (MD) persist in the absence of L4 NMDARs. In contrast, MD-driven depression of deprived-eye responses was impaired in mice lacking L4 NMDARs, as was L4 long-term depression in V1 slices. Our findings reveal a crucial requirement for L4 NMDARs in visual cortical synaptic depression, and a surprisingly negligible role for them in cortical response potentiation. These results demonstrate that NMDARs within distinct cellular subpopulations support different forms of experience-dependent plasticity.
