AbstractA complete control of the localized surface plasmon resonance (LSPR) properties of different types of metal nanoparticles (size, shape, or composition) in a device by facile techniques with high throughput is crucial to intensively study and apply the LSPR effects to improve device performance. Here, a versatile approach is presented to fabricate macroscopic and in‐plane multiplex arrays of plasmonic nanoparticles with well‐defined particle size or composition allocation. The polymer layer (poly(N‐isopropylacrylamide), PNIPAM) spin‐coated on the surface of the substrate is applied as a protective layer to control the growth of the Au nanoparticles in a dip‐coating procedure. The relative contribution of LSPR of each particle type can be controlled by selectively adjusting the particle size or composition at the desired position of multiplex arrays on the same substrate. A synergistic enhanced photocurrent response is observed in the metal–semiconductor system, which is attributed to broadened LSPR enhancement of multiplex composition (Au and Au@Ag) structures from the same substrate. The fabrication procedure presented in this study is highly repeatable and feasible for preparing ordered multiplex nanostructures on the same substrate. Furthermore, this method provides a cost‐effective and versatile platform for design of multiplex plasmonic nanostructures in sensing, solar energy conversion, and optical processing applications.

Published: December 2019

AbstractSilicon has been considered as a promising anode material due to its high theoretical capacity (3579 mAh g−1), however, it suffers from capacity degradation owing to the series of multiscale fractures in the electrode caused by the volume variation (≈300%) during phase transitions. The molecular/structural design of polymeric binders has been pivotal in overcoming the challenges to improve the integrity of Si anode via strong interactions between active materials and binders. In this respect, the covalently crosslinked polyacrylamide (PAM) network, which effectively maintains its mechanical strength and shape, is introduced as a novel binder system for Si active materials. Unlike the thermal crosslinking, the abundant polar‐functional groups, related to the strong interactions between Si and polymer, are not sacrificed in their network by virtue of the in situ polymerization. Through the PAM gel, the Si‐based electrode exhibits a superior capacity of ≈1526 mAh g−1 at an optimized crosslinker concentration after 500 cycles. In addition, the effect of the chemical/mechanical properties of PAM gel on the electrochemical properties of Si is adequately elucidated. The results will provide meaningful insight regarding the design of novel binders, especially in the application of the covalently crosslinked structure to Si‐based electrodes.

AbstractPreconcentration is key for detection from an extremely low concentration solution, but requires separation steps from a large volume of samples using extracting solvents. Here, a simple approach is presented for ultrafast and sensitive microanalysis from a tiny volume of aqueous solutions. In this approach, liquid–liquid nanoextraction in an evaporating thin liquid film on a spinning substrate is coupled with quantitative analysis in one step. The approach is exemplified using a liquid mixture comprising a target compound to be analyzed in water, mixed with extractant oil and co‐solvent ethanol. With rapid evaporation of ethanol, nanodroplets of oil form spontaneously in the film. The compounds are highly concentrated by liquid evaporation and meanwhile extracted to nanodroplets. A detection limit of nanomolar to picomolar is demonstrated for fluorescent model compounds in only ≈5 µL of solution with the entire process taking ≈10 s. The combination of nanoextraction and infrared microscopy also enables simultaneous chemical identification. The dynamics of thin film evaporation are revealed using fast imaging. The principle behind this approach is general, providing a powerful technique for fast and sensitive chemical analysis of a vast library of compounds for environment monitoring, national security, early diagnosis, and many other applications.
Understanding the Crystallographic Phase Relations in Alkali‐Trihalogeno‐Germanates in Terms of Ferroelectric or Antiferroelectric Arrangements of the Tetrahedral GeX3 Units
Authors: Radha Santosh Kumar , Lambrecht Walter R. L. 
Published: December 2019

AbstractThe alkali‐trihalogeno‐germanates AGeX3 with A: Rb or Cs and X a halogen (I, Br, Cl) along with the corresponding stannates (ASnX3) and plumbates (APbX3) exhibit a large variety of crystal structures, some of which are of the perovskite type. These materials, better known as “halide perovskites” have recently gained worldwide attention as promising photovoltaic and more broadly opto‐electronic materials. However, their stability problems relative to the non‐perovskite phases are a major issue. It is shown that some of the phase relations in these materials can be understood in terms of the relative orientation of the GeX3 tetrahedral units, which is ferroelectric (FE) in the perovskite phase but antiferroelectric (AFE) in the competing monoclinic phase. Electrostatic dipole interactions favor the AFE phase and the additional bond formation favors the FE phase. The change in phase is accompanied by a large change in band gap.

AbstractHaim–Munk syndrome (HMS) and Papillon–Lefevre syndrome (PLS) are phenotypic variants of palmoplantar keratoderma (PPK) with progressive early‐onset periodontitis and dental caries. HMS and PLS have been associated with homozygous or compound heterozygous mutations in the lysosomal protease gene Cathepsin C (CTSC). There have been only a few documented cases of CTSC mutations in patients from South‐East Asia. We report the clinical findings of two Cambodian brothers who presented with diffuse, demarcated PPK with transgrediens extending to the elbows and knees, as well as pachyonychia and dental caries. Arachnodactyly and periodontitis were also found in the older brother. Next‐generation sequencing unveiled a homozygous missense variant in CTSC (NM_001814.5: c.1337AC: p.(Asp446Ala)) in both brothers. Both parents were heterozygous for the variant, while an unaffected older brother was homozygous for the wild‐type allele. Our study adds to the spectrum of mutations and associated clinical presentations for this rare genodermatosis.
Was bedeutet die „geplante Nutzungsdauer“ im Konzept der Dauerhaftigkeitsbemessung bei Parkbauten?
Authors: Fingerloos Frank , Gehlen Christoph 
Published: December 2019

AbstractZur Verbesserung der Wirtschaftlichkeit und der Dauerhaftigkeit von Betonbauwerken werden seit einigen Jahren im Rahmen von nationalen und internationalen Forschungsarbeiten leistungsbezogene („performancebasierte“) Konzepte zur differenzierteren Abschätzung des Bauteilwiderstands (Betondichtheit und Betondeckung) unter verschiedenen Umgebungsbedingungen entwickelt und auch schon in einzelnen Bauprojekten erprobt. In diesem Beitrag geht es darum, auf den aktuellen Stand der Wissenschaft – z. T. auch Stand der Technik – einzugehen und auf Chancen und Risiken bei der Anwendung leistungsbezogener Dauerhaftigkeitskonzepte aufmerksam zu machen. Beispielhaft werden die deskriptiven Festlegungen nach aktuellem Stand der Normung in Deutschland und die leistungsbezogene Festlegung des Bauteilwiderstands am Beispiel der chloridinduzierten Bewehrungskorrosion (XD‐Exposition) gegenübergestellt und detailliert erläutert.Darüber hinaus wird der aktuelle Wissensstand zur Korrosionsintensität von Betonstahlbewehrung in Rissen zusammengefasst, in die über maximal eine Wintersaison Chloride aus Tausalz eingedrungen sind. Diese Frage ist essenziell für die Stahlbetonbauweisen in Parkbauten mit und ohne Oberflächenschutzsystemen und wurde auch im DBV‐Merkblatt „Parkhäuser und Tiefgaragen“ aufgegriffen.

AbstractVerkade's superbases, entrapped in the cavity of enantiopure hemicryptophane cages, have been synthesized with enantiomeric excess (ee) superior to 98%. Their absolute configuration has been determined by using electronic circular dichroism (ECD) spectroscopy. These enantiopure encaged superbases turned out to be efficient chiral derivatizing agents for chiral azides, underlining that the chirality of the cycloveratrylene (CTV) macrocycle induces different magnetic and chemical environments around the phosphazide functions.

Published: December 2019

AbstractThe praying mantis is a good model for the study of motor control, especially for investigating the transformation from sensory signals into motor commands. In insects, thoracic ganglia (TG) play an important role in motor control. To understand the functional organization of TG, an atlas is useful. However, except for the fruitfly, no three‐dimensional atlas of TG has not been reported for insects. In this study, we generated a three‐dimensional atlas of prothoracic, mesothoracic, and metathoracic ganglia in the praying mantis (Tenodera aridifolia). First, we observed serial sections of the prothoracic ganglion stained with hematoxylin and eosin to identify longitudinal tracts and transverse commissures. We then visualized neuropil areas by immunostaining whole‐mount TG with an anti‐synapsin antibody. Before labeling each neuropil area, standardization using the iterative shape averaging method was applied to images to make neuropil contours distinct. Neuropil areas in TG were defined based on their shape and relative position to tracts and commissures. Finally, a three‐dimensional atlas was reconstructed from standardized images of the TG. The standard TG are available at the Comparative Neuroscience Platform website (cns.neuroinf.jp/modules/xoonips/detail.php?item_id=11946) and can be used as a common reference map to combine the anatomical data obtained from different individuals.

AbstractAimWe conducted a multicenter study to explore the risk factors of developing pneumonia and the effectiveness of perioperative oral management (POM) for the prevention of pneumonia in postsurgical patients.Methods and resultsA survey covering eight regional hospitals was conducted over 4 years, from April 2010 to March 2014. Using the Diagnosis Procedure Combination database, a target group of 25,554 patients with cancer who underwent surgery was selected and assessed from a population of 346,563 patients without pneumonia on admission (sample population). The study compared the incidence of pneumonia and attempted to identify the significant predictive factors for its occurrence in these patients using multiple logistic regression analysis. Comparative assessment for the occurrence of pneumonia before and after POM implementation showed a significant incidence decrease after POM introduction in the target group, with no such change observed in the sample population. Multiple logistic regression analysis showed that the odds ratio for pneumonia occurrence after POM introduction was 0.44, indicating a reduced risk of pneumonia.ConclusionPOM in cancer patients was indeed effective in reducing the incidence of pneumonia in hospitals and thereby helped in preventing pneumonia during hospitalization.
Electrophoretic ratcheting of spherical particles in well/channel microfluidic devices: Making particles move against the net field
Authors: Wang Hanyang , de Haan Hendrick W. , Slater Gary W. 
Published: December 2019

AbstractWe examine the electrophoresis of spherical particles in microfluidic devices made of alternating wells and narrow channels, including a system previously used to separate DNA molecules. Our computer simulations predict that such systems can be used to separate spherical particles of different sizes that share the same free‐solution mobility. Interestingly, the electrophoretic velocity shows an inversion as the field intensity is increased: while small particles have higher velocities at low field, the situation is reversed at high fields with the larger particles then moving faster. The resulting nonlinearity suggests that asymmetric pulsed electric fields could be used to build separation ratchets: particles then have a net size‐dependent velocity in the presence of a zero‐mean external field. Exploiting the inversion mentioned above, we show how to design pulsed field sequences that make particles move against the mean field (an example of negative mobility). Finally, we demonstrate that it is possible to use pulsed fields to make particles of different sizes move in opposite directions, even though their charge have the same sign.
Seasonal δ13CDIC sourcing and geochemical flux in telogenetic epikarst of south‐central Kentucky
Authors: Jackson Leah , Polk Jason S. 
Published: December 2019

AbstractTelogenetic epikarst carbon sourcing and transport processes and their associated hydrogeochemical responses are complex and dynamic. Carbon dioxide (CO2) transport rates in the epikarst zone are often driven by hydrogeochemical responses, which influence carbonate dissolution and conduit formation. This study examines the influence of land use on carbon sourcing and carbonate dissolution kinetics through a comparative analysis of separate, but similar, epikarst systems in south‐central Kentucky. The use of high‐resolution hydrogeochemical data from multiple data loggers and isotope analysis from collected water samples reflects the processes within these epikarst aquifers, which are estimated to contribute significantly to bedrock dissolution. Results indicate that, in an agricultural setting, long‐term variability and dissolution is governed by seasonal production of CO2. In a more urbanized, shallower epikarst system, land cover may affect CO2 transport between the soil and underlying bedrock. This concentration of CO2 potentially contributes to ongoing dissolution and conduit development, irrespective of seasonality. The observed responses in telogenetic epikarst systems seem to be more similar to eogenetic settings, which is suggested to be driven by CO2 transport occurring independent of high matrix porosity. The results of this study indicate site‐specific responses with respect to both geochemical and δ13CDIC changes on a seasonal scale, despite regional geologic similarities. The results indicate that further comparative analyses between rural and urban landscapes in other karst settings is needed to delineate the impact of land use and seasonality on dissolution and carbon sourcing during karst formation processes. © 2019 John Wiley & Sons, Ltd.
Joint optimization of computation cost and delay for task offloading in vehicular fog networks
Authors: Li Haotian , Li Xujie , Wang Weiguo 
Published: December 2019

AbstractThe vehicles equipped with computing devices can provide computing services in vehicular fog networks, thereby reducing latency and improving system efficiency. Hence, we face with the problem of how to select vehicles for the computation offloading of the task. In this paper, we jointly consider the delay and cost, and study the resource allocation problem of multivehicles users. First of all, we construct a hierarchical offloading model, use mathematical method to construct consumption function of the system, and generate a convex optimization problem with inequality constraints. Then, we use Lagrange method to solve the problem and develop a low‐complexity algorithm to select vehicles, optimize the offloading ratio, and reduce the consumption of the system. Numerical results show that the algorithm has a fast convergence rate and good performance.
On the statistics of the ratio of nonconstrained arbitrary α‐μ random variables: A general framework and applications

Published: December 2019

AbstractIn this paper, we derive closed‐form exact expressions for the main statistics of the ratio of two squared α‐μ random variables, which are of interest in many scenarios for future wireless networks where generalized distributions are more suitable to fit with field data. Importantly, different from previous proposals, our expressions are general in the sense that are valid for nonconstrained arbitrary values of the parameters of the α‐μ distribution. Thus, the probability density function, cumulative distribution function, moment generating function, and higher‐order moments are given in terms of both (i) the Fox H‐function for which we provide a portable and efficient Wolfram Mathematica code and (ii) easily computable series expansions. Our expressions can be used straightforwardly in the performance analysis of a number of wireless communication systems, including either interference‐limited scenarios, spectrum sharing, full‐duplex, or physical‐layer security networks, for which we present the application of the proposed framework. Moreover, closed‐form expressions for some classical distributions, derived as special cases from the α‐μ distribution, are provided as byproducts. The validity of the proposed expressions is confirmed via Monte Carlo simulations.
Effective capacity and outage probability assessment of multiple‐relay cognitive communication systems in Nakagami‐m and Rayleigh fading channel

Published: December 2019

AbstractThe radio spectrum of communication systems is largely occupied by wideband technologies, and thus, efficient usage of spectrum is a crucial requirement from regulators' and service providers' perspectives. Cognitive communication has been proposed as a potential solution to resolve the spectrum scarcity problem. Cognitive radio schemes can be jointly applied with cooperative communications to improve the performance under both overlay and underlay strategies as the two main cognitive strategies supported by multiple relays. This combination significantly improves the reliability and capacity of data communication. In this paper, two QoS parameters, namely, the effective capacity and outage probability, have been thoroughly analyzed in a Nakagami‐m fading channel that is the typical channel condition often considered in the transmission of communication systems. Closed‐form expressions are obtained for effective capacity and outage probability in both underlay and overlay strategies. Simulation results verify the effectiveness of the mathematical modelling of the proposed QoS parameters.

AbstractBlastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and highly aggressive hematological malignancy with a poorly understood pathobiology and no effective therapeutic options. Despite a few recurrent genetic defects (eg, single nucleotide changes, indels, large chromosomal aberrations) have been identified in BPDCN, none are disease‐specific, and more importantly, none explain its genesis or clinical behavior. In this study, we performed the first high resolution whole‐genome analysis of BPDCN with a special focus on structural genomic alterations by using whole‐genome sequencing and RNA sequencing. Our study, the first to characterize the landscape of genomic rearrangements and copy number alterations of BPDCN at nucleotide‐level resolution, revealed that IKZF1, a gene encoding a transcription factor required for the differentiation of plasmacytoid dendritic cell precursors, is focally inactivated through recurrent structural alterations in this neoplasm. In concordance with the genomic data, transcriptome analysis revealed that conserved IKZF1 target genes display a loss‐of‐IKZF1 expression pattern. Furthermore, up‐regulation of cellular processes responsible for cell‐cell and cell‐ECM interactions, which is a hallmark of IKZF1 deficiency, was prominent in BPDCN. Our findings suggest that IKZF1 inactivation plays a central role in the pathobiology of the disease, and consequently, therapeutic approaches directed at reestablishing the function of this gene might be beneficial for patients.
Osteoclasts degrade fibrinogen scaffolds and induce mesenchymal stem/stromal osteogenic differentiation

Published: December 2019

AbstractFibrinogen (Fg) is a pro‐inflammatory protein with pro‐healing properties. Previous work showed that fibrinogen 3D scaffolds (Fg‐3D) promote bone regeneration, but the cellular players were not identified. Osteoclasts are bone resorbing cells that promote bone remodeling in close crosstalk with osteoblasts. Herein, the capacity of osteoclasts differentiated on Fg‐3D to degrade the scaffolds and promote osteoblast differentiation was evaluated in vitro. Fg‐3D scaffolds were prepared by freeze‐drying and osteoclasts were differentiated from primary human peripheral blood monocytes. Results obtained showed osteoclasts expressing the enzymes cathepsin K and tartrate resistant acid phosphatase colonizing Fg‐3D scaffolds. Osteoclasts were able to significantly degrade Fg‐3D, reducing the scaffold's area, and increasing D‐dimer concentration, a Fg degradation product, in their culture media. Osteoclast conditioned media from the first week of differentiation promoted significantly stronger human primary mesenchymal stem/stromal cell (MSC) osteogenic differentiation, evaluated by alkaline phosphatase activity. Moreover, week 1 osteoclast conditioned media promoted earlier MSC osteogenic differentiation, than chemical osteogenesis inductors. TGF‐β1 was found increased in osteoclast conditioned media from week 1, when compared to week 3 of differentiation. Taken together, our results suggest that osteoclasts are able to differentiate and degrade Fg‐3D, producing factors like TGF‐β1 that promote MSC osteogenic differentiation.
