Published: November 2018

AbstractA transparent dual‐band monopole (Inverted‐F) antenna using a micro‐metal mesh film (μ‐MMF) designed on the rear glass of an automobile (Hyundai K5) is presented. This design allows the optically transparent antenna to be installed in a wider space, thus overcoming the space limitation typically posed by roof‐mounted shark‐fin antennas. It can also reasonably solve the problem of low reception sensitivity and radiation interference from antennas operating in other service bands. The antenna is a combination of two simple monopoles operating in the frequency modulation (FM) (88–108 MHz) and the digital media broadcasting (DMB) (174–216 MHz) service bands. Measured reflection coefficients (S11) of the transparent antenna using μ‐MMF are under −6 dB (VSWR 3:1) in both the bands, and the radiation pattern shows directive patterns to the outward direction from the car; the average peak gains in the XY plane are 1.1 dB in the FM service band and 8.8 dB in the DMB service band.

ObjectiveThis study aimed to investigate the effect of a genetic risk score (GRS) comprising 15 single‐nucleotide polymorphisms, previously shown to associate with childhood BMI, on the baseline cardiometabolic traits and the response to a lifestyle intervention in Danish children and adolescents.MethodsChildren and adolescents with overweight or obesity (n = 920) and a population‐based control sample (n = 698) were recruited. Anthropometric and biochemical measures were obtained at baseline and in a subgroup of children and adolescents with overweight or obesity again after 6 to 24 months of lifestyle intervention (n = 754). The effects of the GRS were examined by multiple linear regressions using additive genetic models.ResultsAt baseline, the GRS associated with BMI standard deviation score (SDS) both in children and adolescents with overweight or obesity (β = 0.033 [SE = 0.01]; P = 0.001) and in the population‐based sample (β = 0.065 [SE = 0.02]; P = 0.001). No associations were observed for cardiometabolic traits. The GRS did not influence changes in BMI SDS or cardiometabolic traits following lifestyle intervention.ConclusionsA GRS for childhood BMI was associated with BMI SDS but not with other cardiometabolic traits in Danish children and adolescents. The GRS did not influence treatment response following lifestyle intervention.
Structure Formation in Class I and Class II Hydrophobins at the Air–Water Interface under Multiple Compression/Expansion Cycles

Published: November 2018

AbstractHydrophobins are small amphiphilic fungal proteins empirically divided into two classes. We investigated the self‐assembled structures of class I SC3 from S. commune and class II HFBII from T. reesei transferred to mica from the air–water interface by using the Langmuir–Schaefer (LS) technique and atomic force microscopy (AFM). The main focus is the influence of areal constraint and multiple compressions and expansions on the morphology of the protein films. SC3 shows a rather homogenous coverage of the mica surface, with fibrillary structures. Multiple compressions to a surface pressure of 13 mn m−1 led to a shortening of the fibrils. HFBII exhibits multilayered structures of varying thickness at higher surface pressures. Multiple compressions led to a variety of large, multilayer aggregates. Several compressions and expansions homogenized the films of both types. Both proteins showed similar dendritic structures with relevant length scales of at least several hundred nanometers at pressures of 13 mn m−1 and above, although the primary structures they assemble into are usually different in size and type, and range from fibrils to hexagonally ordered films. These dendritic structures may stem from a combination of mechanical influences, such as compressions, expansions, and the drying effect during LS transfer, which may simulate processes during physiological applications of hydrophobins, such as encapsulation or release of spores.

Published: November 2018

AbstractIntroductionResearch on the volatile oil composition of Thymus kotschyanus Boiss was conducted by applying mesoporous organosilica based on alkylimidazolium ionic liquid (PMO‐IL) as a fibre coating material via a method referred to as microwave‐assisted headspace solid‐phase microextraction (MA‐HS‐SPME).MethodologyThis technique entails microwave irradiation of the sample and collection of the volatile sample components. These components are further introduced into a gas chromatography–mass spectrometry (GC–MS) injection port for further analysis. A simplex method was used for the optimisation of three different parameters affecting the efficiency of the extraction.ConclusionThe MA‐HS‐SPME method proved to be the most suitable technique in oil determination and extraction from Thymus kotschyanus owing to its advantageous aspects of cost effectiveness, simplicity and solvent independence.
Is the tetrakis[2.1.1]bicyclohexano‐cycloocta‐1,3,5,7‐tetraene a good model for the D4h‐1,3,5,7‐cyclooctatetraene?
Authors: Stanger Amnon 
Published: November 2018

AbstractRecently, it was claimed that D4h‐1,3,5,7‐cyclooctatetraene (2) is nonaromatic, according to a definition of aromaticity, which relies of the behavior of excited states. This conclusion is based mainly on MCD studies of tetrakis[2.1.1]bicyclohexano‐1,3,5,7‐cyclooctatetraene (1) and computational work on 2 at different symmetries. In this work, the aromaticity of 2 is studied by ground state criteria—aromatic stabilization energy (ASE) and magnetic properties. The ASE of 2 is studied and compared with those of benzene and cyclobutadiene. NICS(1)π,zz studies of 1 and 2 and comparison with tris‐bicyclo[2.1.1]hexanobenzene and benzene suggests a dramatic reduction of ring currents in the annulated systems. The reason was found to be mixing of the p orbitals of the bridgehead carbon atoms into the central rings π systems. It is unclear whether 2 should be considered antiaromatic, nonaromatic, or aromatic, but it is clear that 1 is not a good model for 2 for aromaticity studies purposes according to ground‐state properties (energy and magnetic).

Published: November 2018

ABSTRACTAdditive manufacturing (AM), otherwise known as three‐dimensional (3D) printing, is driving major innovations in many areas, such as engineering, manufacturing, art, education, and medicine. Although a considerable amount of progress has been made in this field, additional research work is required to overcome various remaining challenges. Recently, one of the actively researched areas lies in the AM of smart materials and structures. Electroactive materials incorporated in 3D printing have given birth to 4D printing, where 3D printed structures can perform as actuating and/or sensing systems, making it possible to deliver electrical signals under external mechanical stimuli and vice versa. In this paper, we present a lightweight, low cost piezoelectric material based on the dispersion of inorganic ferroelectric submicron particles in a polymer matrix. We report on how the proposed material is compatible with the AM process. Finally, we discuss its potential applications for healthcare, especially in smart implants prostheses. © 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2019, 57, 109–115

AbstractObjectiveCancer patients experience reproductive concerns from diagnosis through to survivorship. However, research has yet to investigate the degree of fertility‐related psychological distress at different treatment time points: diagnosis, treatment, and survivorship. Currently, cancer patients are offered fertility counselling at the time of diagnosis, to assist fertility preservation decision making. A systematic review of the short‐term and long‐term psychological impact of infertility in cancer patients would inform on an improved, longitudinal model of psychological care.MethodsA systematic review of the literature was conducted in January 2018 utilising electronic databases Medline, EMBASE, PSYCH Info, Web of Science, and SCOPUS. An initial search identified 708 potentially relevant studies. Literature was assessed that reported on fertility‐related psychological distress experienced by male and female cancer patients of reproductive age (<45 years) across oncology treatment time points.ResultsA total of 47 papers were included within the final review. Fertility‐related psychological distress persists from diagnosis through to survivorship, with cancer patients reporting a range of negative emotional experiences brought about by threatened infertility. In survivorship, reproductive concerns, unfulfilled desire for a child, nulliparous status, and early menopause were linked to higher rates of mental health disorders and psychological distress.ConclusionsFertility‐related psychological distress is prevalent and persistent in cancer patients and survivors. As such, patients and survivors would greatly benefit from fertility‐related psychological support implemented into standard practice from diagnosis through to survivorship. A revised model of care is proposed.
Structural versatility that serves the function of the HRD motif in the catalytic loop of protein tyrosine kinase, Src
Authors: Cui Yixin , Sun Gongqin 
Published: November 2018

AbstractSite‐directed mutagenesis is a traditional approach for structure–function analysis of protein tyrosine kinases, and it requires the generation, expression, purification, and analysis of each mutant enzyme. In this study, we report a versatile high throughput bacterial screening system that can identify functional kinase mutants by immunological detection of tyrosine phosphorylation. Two key features of this screening system are noteworthy. First, instead of blotting bacterial colonies directly from Agar plates to nitrocellulose membrane, the colonies were cultured in 96‐well plates, and then spotted in duplicate onto the membrane with appropriate controls. This made the screening much more reliable compared with direct colony blotting transfer. A second feature is the parallel use of a protein tyrosine phosphatase (PTP)‐expressing host and a non‐PTP‐expressing host. Because high activity Src mutants are toxic to the host, the PTP system allowed the identification of Src mutants with high activity, while the non‐PTP system identified Src mutants with low activity. This approach was applied to Src mutant libraries randomized in the highly conserved HRD motif in the catalytic loop, and revealed that structurally diverse residues can replace the His and Arg residues, while the Asp residue is irreplaceable for catalytic activity.

Published: November 2018

AbstractWe review the advanced version of the KKLT construction and pure de Sitter supergravity, involving a nilpotent multiplet, with regard to various conjectures that de Sitter state cannot exist in string theory. We explain why we consider these conjectures problematic and not well motivated, and why the recently proposed alternative string theory models of dark energy, ignoring vacuum stabilization, are ruled out by cosmological observations at least at the 3σ level, i.e. with more than 99.7% confidence.
Deformed Weitzenböck Connections and Double Field Theory
Authors: Penas Victor A. 
Published: November 2018

AbstractWe revisit the generalized connection of Double Field Theory. We implement a procedure that allow us to re‐write the Double Field Theory equations of motion in terms of geometric quantities (like generalized torsion and non‐metricity tensors) based on other connections rather than the usual generalized Levi‐Civita connection and the generalized Riemann curvature. We define a generalized contorsion tensor and obtain, as a particular case, the Teleparallel equivalent of Double Field Theory. To do this, we first need to revisit generic connections in standard geometry written in terms of first‐order derivatives of the vielbein in order to obtain equivalent theories to Einstein Gravity (like for instance the Teleparallel gravity case). The results are then easily extrapolated to DFT.

AbstractBACKGROUNDBursaphelenchus xylophilus is a migratory endoparasitic nematode known to cause severe environmental damage and economic losses in pine forest ecosystems. This present study investigated the nematicidal metabolites of actinomycetes in vitro and evaluated the disease control efficacy of the active compound and metabolites under greenhouse and field conditions.RESULTSFive thousand types of actinobacteria from Korean forest soil samples were screened to identify novel nematicidal agents against the pine wood nematode. Streptomyces sp. AN091965 showed the strongest nematicidal activity. One active compound, spectinabilin, was obtained by nematicidal asssy‐directed fractionation, and it showed significant nematicidal activity against B. xylophilus, with an LC50 value of 0.84 µg mL−1. Spectinabilin effectively suppressed the development of pine wilt disease in 5‐year‐old Pinus densiflora trees, even at 0.9 mg per tree under greenhouse conditions. Moreover, the acetone extract of the active strain's mycelia efficiently suppressed the development of pine wilt disease under field conditions.CONCLUSIONTo the best of our knowledge, this the first report to describe the nematicidal activity of spectinabilin against B. xylophilus. The cell extracts described herein merit further field studies as potential nematicides against the pine wood nematode. © 2018 Society of Chemical Industry

AbstractPurposeThis study evaluated the current status of reproductive disorders and provision of information on oncofertility to female adolescent and young adult (AYA) cancer patients in Japan.MethodsA national survey of AYA cancer survivors was conducted. Children were <15 years old, and AYAs were 15‐39 years old. Results from the survivors of other than gynecological disease who underwent chemotherapy were analyzed.ResultsAmong the survivors, 41.4% were concerned about their reproductive function and infertility, and 36.2% were aware of menstrual cycle abnormalities. Among them, 15.5% (n = 20) of all and 21.2% (n = 17) of the AYA‐onset survivors suffered infertility due to chemo‐ or radiotherapy and gave up childbearing. These rates were significantly higher than those of healthy AYAs. Although 80.8% of AYA‐onset survivors answered that they had received information on reproductive function and infertility, only 55.8% had received information on fertility preservation methods. Furthermore, only 22.4% of all and 42.3% of AYA‐onset survivors had received pretreatment information on fertility preservation methods.ConclusionsNot a few AYA cancer survivors reported reproductive dysfunction. These findings indicate that information provided on therapy‐related problems before cancer treatment in Japan was insufficient and highlight the need to improve patient decision‐making and support systems for fertility preservation.
A process‐based approach to restoring depositional river valleys to Stage 0, an anastomosing channel network
Authors: Powers Paul D. , Helstab Matt , Niezgoda Sue L. 
Published: November 2018

AbstractStream restoration approaches most often quantify habitat degradation, and therefore recovery objectives, on aquatic habitat metrics based on a narrow range of species needs (e.g., salmon and trout), as well as channel evolution models and channel design tools biased toward single‐threaded, and “sediment‐balanced” channel patterns. Although this strategy enhances perceived habitat needs, it often fails to properly identify the underlying geomorphological and ecological processes limiting species recovery and ecosystem restoration. In this paper, a unique process‐based approach to restoration that strives to restore degraded stream, river, or meadow systems to the premanipulated condition is presented. The proposed relatively simple Geomorphic Grade Line (GGL) design method is based on Geographic Information System (GIS) and field‐based analyses and the development of design maps using relative elevation models that expose the relic predisturbance valley surface. Several case studies are presented to both describe the development of the GGL method and to illustrate how the GGL method of evaluating valley surfaces has been applied to Stage 0 restoration design. The paper also summarizes the wide applicability of the GGL method, the advantages and limitations of the method, and key considerations for future designers of Stage 0 systems anywhere in the world. By presenting this ongoing Stage 0 restoration work, the authors hope to inspire other practitioners to embrace the restoration of dynamism and diversity through restoring the processes that create multifaceted river systems that provide long‐term resiliency, meta‐stability, larger and more complex and diverse habitats, and optimal ecosystem benefits.

Published: November 2018

AbstractZn/N‐doped CuO have been prepared by a series of processes like stirring, soaking and calcination. Firstly, Zn‐ZIF precursors were synthesized by a simple stirring method, which is the source of Zn element. And then after a series of soaking and calcination, CuO hydrangeas doped with Zn/N were successfully synthesized. The calcination temperature was changed to control the samples’ morphology and their performances. The obtained samples showed different electrocatalytic properties in 1 M KOH solution. These samples were characterized by scanning electron microscopy (SEM), X‐ray powder diffraction (XRD), high resolution transmission electron microscope (HRTEM), energy dispersive X‐ray spectroscopy (EDS) and thermogravimetric analysis (TGA). Electrocatalytic properties of the three samples have been briefly discussed.

AbstractIn this work, we report a comprehensive photovoltaic investigation of a structurally simple Donor‐Acceptor (D−A) configured organic dye, N,N‐PABA as an active co‐sensitizer in DSSCs sensitized with well‐known Ru (II) based N3 dye. This effective co‐sensitizer (N,N‐PABA) comprises N,N‐dimethylaniline system as a donor scaffold linked with 4‐aminobenzoic acid as an electron withdrawing functionality. In the present study, we have demonstrated the profound effect of concentration of sensitizer, i. e. N3 based dye as well as co‐sensitizer, i. e. N,N‐PABA on the photovoltaic performance characteristics of solar cells. Interestingly, the best photovoltaic performance was obtained for the co‐sensitized device fabricated using 0.2 mM of N,N‐PABA along with 0.3 mM of N3 sensitizer, in presence of 20 mM of CDCA. It displayed power conversion efficiency (PCE) of 5.82% with JSC of 14.35 mA.cm−2, VOC of 0.626 V and FF of 64.85%. Here, the N,N‐PABA effectively filled the absorption valley, avoided the dye aggregation and reduced the charge recombination in the co‐sensitized devices. Thus, the results ameliorate the role of efficient co‐sensitizers to yield DSSC with improved performance by the selection of a matchable co‐sensitizer at an appropriate concentration.
Kollaborierende Roboter in der Pflege – Sicherheit in der Mensch-Maschine-Schnittstelle
Authors: Buxbaum Hans , Sen Sumona 
Published: November 2018

ZusammenfassungDie Mensch-Roboter-Kollaboration ist eine neue Anwendungsrichtung der Robotik, die in den letzten Jahren zunächst im industriellen Bereich eingeführt wurde und dort schnell auch Anwendung fand. Im Zuge der Industrie-4.0-Kampagnen wurden zunehmend innovative Robotersysteme entwickelt, die ohne Schutzzäune in einer direkten Kollaboration mit Menschen eingesetzt werden können. Nachdem im Bereich der Service- und Pflegeautomatisierung versucht wurde, Lösungsansätze mit speziellen Systementwicklungen zu finden, zeichnet sich heute ab, dass auch eine Verwendung der nunmehr vorhandenen Konzepte und Systeme aus der industriellen Mensch-Roboter-Kollaboration zielführend sein kann. Denn hier stehen geeignete Robotersysteme, Verfahren sowie neuartige Schutzkonzepte zur Verfügung. Eine Übertragung auf die Voraussetzungen der Service- oder Pflegeautomatisierung scheint prinzipiell möglich. Dieser Beitrag stellt Konzepte und Systeme der Mensch-Roboter-Kollaboration vor und fokussiert sodann auch die wichtige Thematik der Sicherheit in der Mensch-Maschine-Schnittstelle. Die aktuellen Normen zu den zulässigen Betriebsarten werden eingeführt und die verschiedenen Betriebsarten werden auf die Anwendbarkeit im Bereich der Pflegerobotik hin untersucht. Abschließend wird das Konzept eines Full-Scope-Simulators vorgestellt, der mit Probandenexperimenten unter konstanten Umweltbedingungen Untersuchungen zu Situation Awareness, gefühlter Sicherheit und fokussierter Aufmerksamkeit erlauben soll.
