Én stavelse, to synsvinkler – børns tilegnelse af dialogiske partikler
Authors: Thomsen Ditte Boeg
Published: November 2016

Children’s understanding of others as mental beings with feelings and beliefs develops radically during early childhood, and studies in the ontogeny of complement-clause constructions (e.g. Brandt et al. 2010) and evidential affixes (Choi 2006) show that children also begin to acquire linguistic tools for communicating about these perspectives early in their development. However, it is less well known how children acquire viewpoint constructions that are less salient in their input than complement-clause constructions and evidential affixes, i.e. how motivated children are to look for interpersonal meanings without strong linguistic cues. Danish dialogic particles are optional, stressless, utterance-medial monosyllables specifying how interlocutors’ understandings converge and differ (Davidsen-Nielsen 1996). Through a spontaneous-speech analysis of a kindergarten corpus (94 hours, 16 children: 1;10-3;8 to 4;6-6;3 years), I here show that Danish preschoolers begin to use these inconspicuous particles in group interactions during their fourth year of life, and that they develop a nuanced repertoire during the following two years. This is a strong indicator of children’s stable monitoring of perspectives and their motivation to generalize over situations with common perspectival traits – even in the absence of salient linguistic cues.

Divisive suppression explains high-precision firing and contrast adaptation in retinal ganglion cells
Authors: Cui Yuwei , Wang Yanbin V , Park Silvia J H , Demb Jonathan B , Butts Daniel A
Published: November 2016

Visual processing depends on specific computations implemented by complex neural circuits. Here, we present a circuit-inspired model of retinal ganglion cell computation, targeted to explain their temporal dynamics and adaptation to contrast. To localize the sources of such processing, we used recordings at the levels of synaptic input and spiking output in the in vitro mouse retina. We found that an ON-Alpha ganglion cell's excitatory synaptic inputs were described by a divisive interaction between excitation and delayed suppression, which explained nonlinear processing that was already present in ganglion cell inputs. Ganglion cell output was further shaped by spike generation mechanisms. The full model accurately predicted spike responses with unprecedented millisecond precision, and accurately described contrast adaptation of the spike train. These results demonstrate how circuit and cell-intrinsic mechanisms interact for ganglion cell function and, more generally, illustrate the power of circuit-inspired modeling of sensory processing.
Metal–insulator–metal photomonitor for optical waveguides at telecom wavelengths
Authors: Ishii Satoshi , Baghdasaryan Hovik , Marciniak Marian , Otomo Akira
Published: November 2016

A compact photodetector for an optical waveguide that is easy to integrate is necessary for optical on-chip devices. We demonstrate that a metallic contact covering an optical waveguide can monitor guided light in the 680 to 1550 nm wavelength range without blocking it. The contact is made of Au, titania, and Ti thin films that form a metal–insulator–metal structure. A concise design and facile fabrication process make our device particularly suitable for optical waveguides made of insulators such as polymers and dielectrics.

Characteristics of yttrium fluoride and yttrium oxide coatings for plasma process equipment prepared by atmospheric plasma spraying
Authors: Lin Tzu-Ken , Wuu Dong-Sing , Huang Shih-Yung , Wang Wei-Kai
Published: November 2016

In this study, yttrium fluoride (YF3) and yttrium oxide (Y2O3) coatings were prepared by an atmospheric plasma spraying technique and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). YF3 powders were sprayed at various plasma spraying powers of 9, 15, and 21 kW. The XRD result indicates that the YF3 coating shows preferred orientations and was well crystallized. The XPS results revealed a strong Y–F bond on the YF3 coating surface. A porosity value analysis showed that the porosity of the YF3 coating was lower than that of the Y2O3 coating. Moreover, the dielectric strength of the YF3 coating (22.65 kV/mm) was higher than that of the Y2O3 coating (14.42 kV/mm). This confirms that the YF3 coating exhibits a breakdown voltage of 4.97 kV, which is more than 1.5 times higher than that observed for the Y2O3 coating (3.29 kV). These results indicate that the YF3 coating has better mechanical and dielectric properties than the Y2O3 coating, indicating that the YF3 coating is a very attractive novel antiplasma and corrosion-resistant material.

Ship space to database: emerging infrastructures for studies of the deep subseafloor biosphere
Authors: Darch Peter T. , Borgman Christine L.
Published: November 2016

Background

An increasing array of scientific fields face a “data deluge.” However, in many fields data are scarce, with implications for their epistemic status and ability to command funding. Consequently, they often attempt to develop infrastructure for data production, management, curation, and circulation. A component of a knowledge infrastructure may serve one or more scientific domains. Further, a single domain may rely upon multiple infrastructures simultaneously. Studying how domains negotiate building and accessing scarce infrastructural resources that they share with other domains will shed light on how knowledge infrastructures shape science.

Methods

We conducted an eighteen-month, qualitative study of scientists studying the deep subseafloor biosphere, focusing on the Center for Dark Energy Biosphere Investigations (C-DEBI) and the Integrated Ocean Drilling Program (IODP) and its successor, the International Ocean Discovery Program (IODP2). Our methods comprised ethnographic observation, including eight months embedded in a laboratory, interviews (n = 49), and document analysis.

Results

Deep subseafloor biosphere research is an emergent domain. We identified two reasons for the domain’s concern with data scarcity: limited ability to pursue their research objectives, and the epistemic status of their research. Domain researchers adopted complementary strategies to acquire more data. One was to establish C-DEBI as an infrastructure solely for their domain. The second was to use C-DEBI as a means to gain greater access to, and reconfigure, IODP/IODP2 to their advantage. IODP/IODP2 functions as infrastructure for multiple scientific domains, which creates competition for resources. C-DEBI is building its own data management infrastructure, both to acquire more data from IODP and to make better use of data, once acquired.

Discussion

Two themes emerge. One is data scarcity, which can be understood only in relation to a domain’s objectives. To justify support for public funding, domains must demonstrate their utility to questions of societal concern or existential questions about humanity. The deep subseafloor biosphere domain aspires to address these questions in a more statistically intensive manner than is afforded by the data to which it currently has access. The second theme is the politics of knowledge infrastructures. A single scientific domain may build infrastructure for itself and negotiate access to multi-domain infrastructure simultaneously. C-DEBI infrastructure was designed both as a response to scarce IODP/IODP2 resources, and to configure the data allocation processes of IODP/IODP2 in their favor.
SNF: synthesizing high performance NFV service chains
Authors: Katsikas Georgios P. , Enguehard Marcel , Kuźniar Maciej , Maguire Jr Gerald Q. , Kostić Dejan
Published: November 2016

In this paper we introduce SNF, a framework that synthesizes (S) network function (NF) service chains by eliminating redundant I/O and repeated elements, while consolidating stateful cross layer packet operations across the chain. SNF uses graph composition and set theory to determine traffic classes handled by a service chain composed of multiple elements. It then synthesizes each traffic class using a minimal set of new elements that apply single-read-single-write and early-discard operations. Our SNF prototype takes a baseline state of the art network functions virtualization (NFV) framework to the level of performance required for practical NFV service deployments. Software-based SNF realizes long (up to 10 NFs) and stateful service chains that achieve line-rate 40 Gbps throughput (up to 8.5x greater than the baseline NFV framework). Hardware-assisted SNF, using a commodity OpenFlow switch, shows that our approach scales at 40 Gbps for Internet Service Provider-level NFV deployments.
Do Emergency Medicine Residents Prefer Resident‐initiated or Attending‐initiated Feedback?

Published: November 2016

Background

Real‐time feedback is crucial to improving physician performance. Emerging theory suggests that learner‐initiated feedback may be more effective in changing performance than attending‐initiated feedback, but little is known about how residents perceive resident‐ versus attending‐initiated feedback.

Objectives

The primary aim was to determine whether residents' satisfaction varied by learner‐versus attending‐initiated feedback encounters. We hypothesized that residents would be more satisfied with resident‐initiated feedback.

Methods

This was a multicenter study of five emergency medicine residency programs. We developed a milestones‐based, real‐time feedback intervention that provided behavioral anchors for ED subcompetencies and prompted a feedback discussion. The intervention was implemented at all sites for a 3‐month period from March to November 2014. Residents were asked to initiate one card per shift; attendings were also invited to initiate encounters and, in either instance, asked to provide one specific suggestion for improvement. Residents confidentially rated their satisfaction with feedback on a 10‐point scale. Reported satisfaction was categorized as “very satisfied” (score of 10) versus “less than very satisfied” (score < 10). Logistic regression was used to assess the difference in satisfaction between resident‐ versus attending‐initiated feedback, and random effects were used to account for the clustering of repeated ratings within resident and by site.

Results

A total of 785 cards was collected from five sites. Participation varied by site (range = 21–487 cards per site). Of the 587 cards with both feedback initiator and satisfaction data, 67% (396/587) were resident‐initiated, and median satisfaction score was 10 (range = 4–10). There was no difference in the odds of being “very satisfied” by resident‐ vesus attending‐initiated encounters (odds ratio = 1.08, 95% confidence interval = 0.41 to 2.83).

Conclusions

Our results suggest that residents are likely to be as satisfied with self‐initiated feedback as attending‐initiated feedback. Further research is needed to determine whether resident‐initiated feedback is more likely to be incorporated into practice and result in objective performance improvements.
Electrodeposition of insulating poly(phenylene oxide) films with variable thickness

Published: November 2016

Ability to control key characteristics of electrodeposited polymers plays a vital role for their applications. In this work the results on tailoring the thickness of electronically insulating poly(phenylene oxide) (PPO) type polymer films have been showed. Pinhole‐free PPO films with variable thickness in the range of 10–50 nm were grown by controlling the potential applied during the electrochemical polymerization on the surface of titanium nitride (TiN) substrates. The insulating properties of the PPO film were confirmed by testing its permeability to redox species by cyclic voltammetry. Thermal stability of the PPO films with different thicknesses was investigated by in‐situ spectroscopic ellipsometry up to 400 °C in various environments. This insight is important for the optimization of the PPO anneal conditions in order to remove the residual solvent and potentially improve the polymer chains stacking. Our results provide the basis for electrodeposition of PPO films with variable thickness for diverse applications. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44533.

Chronic inflammation plays an important role in tumor progression. The aim of this analysis was to evaluate whether inflammatory biomarkers such as the Glasgow prognostic score (GPS), the neutrophil‐lymphocyte ratio (NLR), the platelet‐lymphocyte ratio (PLR), and the lymphocyte‐monocyte ratio (LMR) could predict the prognosis of nasopharyngeal carcinoma (NPC). In this analysis, pretreatment GPS, NLR, PLR, LMR of 388 patients who were diagnosed as nonmetastatic NPC and recruited prospectively in the 863 Program No. 2006AA02Z4B4 were assessed. Of those, the 249 cases enrolled between December 27th 2006 and July 31st 2011 were defined as the development set. The rest 139 cases enrolled between August 1st 2011 and July 31st 2013 were defined as the validation set. The variables above were analyzed in the development set, together with age, gender, Karnofsky performance score, T stage, and N stage, with respect to their impact on the disease‐specific survival (DSS) through a univariate analysis. The candidate prognostic factors then underwent a multivariate analysis. A nomogram was established to predict the DSS, by involving the independent prognostic factors. Its predction capacity was evaluated through calculating Harrell's concordance index (C‐index) in the validation set. After multivariate analysis for the development set, age (≤50 vs. >50 years old), T stage (T1–2 vs. T3–4), N stage (N0–1 vs. N2–3) and pretreatment GPS (0 vs. 1–2), NLR (≤2.5 vs. >2.5), LMR (≤2.35 vs. >2.35) were independent prognostic factors of DSS (P values were 0.002, 0.008, <0.001, 0.004, 0.018, and 0.004, respectively). A nomogram was established by involving all the factors above. Its C‐index for predicting the DSS of the validation set was 0.734 (standard error 0.056). Pretreatment GPS, NLR, and LMR were independent prognostic factors of NPC. The nomogram based on them could be used to predict the DSS of NPC patients.

Efficient Synthesis of Glycosylated Matijin‐Su Derivatives via Ultrasonic Irradiation
Authors: Liang Guangping , Hu Zhanxing , Yuan Jie , Liang Guangyi , Xu Bixue
Published: November 2016

Matijin‐Su (1) is a phenylalanine dipeptide compound with anti‐hepatitis B virus (HBV) activity. Previous reports suggest that the synthesis of glycosylated Matijin‐Su derivatives needs at least 10 steps. To simplify the synthetic procedure, we have developed a shorter and more efficient method for the preparation via ultrasound irradiation. Two galactopyranosylated (2) and two glucopyranosylated (3) derivatives were synthesized in 6 or 7 steps. The overall yields for the total synthesis of galactopyranosylated derivatives were markedly increased to 39% (2a) or 22% (2b). And the yields for glucopyranosylated derivatives also reached 29% (3a) or 16% (3b).

Rh(I)‐Catalyzed Arylation of α‐Diazo Phosphonates with Aryl Boronic Acids: Synthesis of Diarylmethylphosphonates
Authors: Zhou Yujing , Zhang Yan , Wang Jianbo
Published: November 2016

An efficient synthetic method for diarylmethylphosphonates is presented. A series of phosphonate derivatives with diverse functional groups can be accessed via a rhodium catalyzed cross‐coupling reaction between α‐diazo phosphonates and aryl boronic acids. Migratory insertion of rhodium carbene intermediates is postulated to be the critical step in this transformation.
Impact of cordon‐bleu expression on actin cytoskeleton architecture and dynamics
Authors: Grega‐Larson Nathan E. , Crawley Scott W. , Tyska Matthew J.
Published: November 2016

Cordon‐bleu (COBL) is a multifunctional WASP‐Homology 2 (WH2) domain‐containing protein implicated in a wide variety of cellular functions ranging from dendritic arborization in neurons to the assembly of microvilli on the surface of transporting epithelial cells. In vitro biochemical studies suggest that COBL is capable of nucleating and severing actin filaments, among other activities. How the multiple activities of COBL observed in vitro contribute to its function in cells remains unclear. Here, we used live imaging to evaluate the impact of COBL expression on the actin cytoskeleton in cultured cells. We found that COBL induces the formation of dynamic linear actin structures throughout the cytosol. We also found that stabilizing these dynamic structures with the parallel actin‐bundling protein espin slows down their turnover and enables the robust formation of self‐supported protrusions on the dorsal cell surface. Super‐resolution imaging revealed a global remodeling of the actin cytoskeleton in cells expressing these two factors. Taken together, these results provide insight as to how COBL contributes to the assembly of actin‐based structures such as epithelial microvilli. © 2016 Wiley Periodicals, Inc.
Flood hazards at ford stream crossings on ephemeral channels (south‐east coast of Spain)
Authors: Conesa‐García Carmelo , García‐Lorenzo Rafael , Pérez‐Cutillas Pedro
Published: November 2016

Most road‐stream crossings over ephemeral channels are vulnerable to extreme hydrologic events. Ford stream crossings (FSCs) are usually dangerous for the road traffic during periods of high flow, in particular under flash flood conditions. The present paper analyzes the flood hazards on the Mediterranean coast in the Region of Murcia (south‐east Spain), affecting this type of road‐stream crossing over dry channels, according to hydraulic variables and bedload transport rates estimated for discharges at bankfull and flood‐prone stages. Under such conditions, the safety of people and vehicles was obtained using numerical models, developed by previous researchers; in particular, water levels and flow velocities across ford reaches were compared with different trend curves between water depths and corresponding critical velocities for children and adults, and for various prototype vehicles. Specifically, two approaches to assess this type of hazards were proposed: a specific Hydraulic Hazard Index and an algorithm for estimating the flood hazard from criteria of bed stability and bedload transport capacity (Flood Hazard at Fords, FHF). In addition, different exposure levels were established, using a Flood Vulnerability Index, based on the FHF, the road category, and the annual average daily traffic. The FHF model gave the best results with regard to the magnitude of the damage observed in recent flash floods for flow stages similar to those simulated. According to the danger thresholds established for this index, half‐bankfull flows represent here a high risk: 27.3% of FSCs for mini‐cars and 18.2% for large cars. At bankfull, the FHF exhibits very high values for mini‐cars (77.3% of FSCs) and for large passenger vehicles (50% of FSCs), while at the floodprone stage, extreme FHF values are reached for all kinds of vehicles at most of the ford crossings.
Plateletpheresis efficiency and mathematical correction of software‐derived platelet yield prediction: A linear regression and ROC modeling approach

Published: November 2016

Background

Advances in automated cell separators have improved the efficiency of plateletpheresis and the possibility of obtaining double products (DP). We assessed cell processor accuracy of predicted platelet (PLT) yields with the goal of a better prediction of DP collections.

Study design and methods

This retrospective proof‐of‐concept study included 302 plateletpheresis procedures performed on a Trima Accel v6.0 at the apheresis unit of a hematology department. Donor variables, software predicted yield and actual PLT yield were statistically evaluated. Software prediction was optimized by linear regression analysis and its optimal cut‐off to obtain a DP assessed by receiver operating characteristic curve (ROC) modeling.

Results

Three hundred and two plateletpheresis procedures were performed; in 271 (89.7%) occasions, donors were men and in 31 (10.3%) women. Pre‐donation PLT count had the best direct correlation with actual PLT yield (r = 0.486. P < .001). Means of software machine‐derived values differed significantly from actual PLT yield, 4.72 × 1011 vs.6.12 × 1011, respectively, (P < .001). The following equation was developed to adjust these values: actual PLT yield= 0.221 + (1.254 × theoretical platelet yield). ROC curve model showed an optimal apheresis device software prediction cut‐off of 4.65 × 1011 to obtain a DP, with a sensitivity of 82.2%, specificity of 93.3%, and an area under the curve (AUC) of 0.909.

Conclusion

Trima Accel v6.0 software consistently underestimated PLT yields. Simple correction derived from linear regression analysis accurately corrected this underestimation and ROC analysis identified a precise cut‐off to reliably predict a DP.
Biosynthesis of graphene‐metal nanocomposites using plant extract and their biological activities
Authors: Wen Jing , Salunke Bipinchandra K , Kim Beom Soo
Published: November 2016

BACKGROUND

Recently, numerous studies have utilized graphene/nanoparticle hybrid materials in bioapplications such as biosensing, bioimaging, photothermal therapies, delivery of drugs and genes, and stem cell and tissue engineering applications. In this study, we demonstrate a new, simple, low cost, environmentally safe process for the biosynthesis of graphene/silver (GN/Ag) and graphene/gold (GN/Au) nanocomposites usingXanthium strumariumplant extract.

RESULTS

After synthesis of Ag or Au nanoparticles by treatment of an aqueous solution ofAgNO3orHAuCl4withXanthium strumariumplant extract, graphite was added to the synthesized nanoparticle solution and sonicated in the ultrasonication bath. The synthesized nanocomposites were characterized byUV‐visible spectroscopy, transmission electron microscopy, scanning electron microscopy, X‐ray photoelectron spectroscopy, X‐ray diffraction, Raman spectroscopy, and energy dispersive X‐ray spectroscopy.GN/Ag andGN/Au nanocomposites showed higher antimicrobial activity and higher peroxidase‐like activity, respectively, than individual nanoparticles, graphene alone, or reaction product without plant extract.

CONCLUSION

The present results show thatGN/Ag andGN/Au nanocomposites can be ecofriendly synthesized usingXanthium strumariumleaf extract. The graphene/metal nanocomposites produced may be less‐toxic, biocompatible, and useful for bioapplications. © 2016 Society of Chemical Industry
