Optical tracking of nanoscale particles in microscale environments
Authors: Mathai P. P. , Liddle J. A. , Stavis S. M.
Published: March 2016

The trajectories of nanoscale particles through microscale environments record useful information about both the particles and the environments. Optical microscopes provide efficient access to this information through measurements of light in the far field from nanoparticles. Such measurements necessarily involve trade-offs in tracking capabilities. This article presents a measurement framework, based on information theory, that facilitates a more systematic understanding of such trade-offs to rationally design tracking systems for diverse applications. This framework includes the degrees of freedom of optical microscopes, which determine the limitations of tracking measurements in theory. In the laboratory, tracking systems are assemblies of sources and sensors, optics and stages, and nanoparticle emitters. The combined characteristics of such systems determine the limitations of tracking measurements in practice. This article reviews this tracking hardware with a focus on the essential functions of nanoparticles as optical emitters and microenvironmental probes. Within these theoretical and practical limitations, experimentalists have implemented a variety of tracking systems with different capabilities. This article reviews a selection of apparatuses and techniques for tracking multiple and single particles by tuning illumination and detection, and by using feedback and confinement to improve the measurements. Prior information is also useful in many tracking systems and measurements, which apply across a broad spectrum of science and technology. In the context of the framework and review of apparatuses and techniques, this article reviews a selection of applications, with particle diffusion serving as a prelude to tracking measurements in biological, fluid, and material systems, fabrication and assembly processes, and engineered devices. In so doing, this review identifies trends and gaps in particle tracking that might influence future research.
Coarse-grained molecular simulations of allosteric cooperativity
Authors: Nandigrami Prithviraj , Portman John J.
Published: March 2016

Interactions between a protein and a ligand are often accompanied by a redistribution of the population of thermally accessible conformations. This dynamic response of the protein’s functional energy landscape enables a protein to modulate binding affinities and control binding sensitivity to ligand concentration. In this paper, we investigate the structural origins of binding affinity and allosteric cooperativity of binding two Ca2+ ions to each domain of Calmodulin (CaM) through simulations of a simple coarse-grained model. In this model, the protein’s conformational transitions between open and closed conformational ensembles are simulated explicitly and ligand binding and unbinding are treated implicitly within the grand canonical ensemble. Ligand binding is cooperative because the binding sites are coupled through a shift in the dominant conformational ensemble upon binding. The classic Monod-Wyman-Changeux model of allostery with appropriate binding free energies to the open and closed ensembles accurately describes the simulated binding thermodynamics. The simulations predict that the two domains of CaM have distinct binding affinity and cooperativity. In particular, the C-terminal domain binds Ca2+ with higher affinity and greater cooperativity than the N-terminal domain. From a structural point of view, the affinity of an individual binding loop depends sensitively on the loop’s structural compatibility with the ligand in the bound ensemble, as well as the conformational flexibility of the binding site in the unbound ensemble.
Density functional theory based study of chlorine doped WS2-metal interface
Authors: Chanana Anuja , Mahapatra Santanu
Published: March 2016

Investigation of a transition metal dichalcogenide (TMD)-metal interface is essential for the effective functioning of monolayer TMD based field effect transistors. In this work, we employ the Density Functional Theory calculations to analyze the modulation of the electronic structure of monolayer WS2 with chlorine doping and the relative changes in the contact properties when interfaced with gold and palladium. We initially examine the atomic and electronic structures of pure and doped monolayer WS2 supercell and explore the formation of midgap states with band splitting near the conduction band edge. Further, we analyze the contact nature of the pure supercell with Au and Pd. We find that while Au is physiosorbed and forms n-type contact, Pd is chemisorped and forms p-type contact with a higher valence electron density. Next, we study the interface formed between the Cl-doped supercell and metals and observe a reduction in the Schottky barrier height (SBH) in comparison to the pure supercell. This reduction found is higher for Pd in comparison to Au, which is further validated by examining the charge transfer occurring at the interface. Our study confirms that Cl doping is an efficient mechanism to reduce the n-SBH for both Au and Pd, which form different types of contact with WS2.
Construction of initial vortex-surface fields and Clebsch potentials for flows with high-symmetry using first integrals
Authors: He Pengyu , Yang Yue
Published: March 2016

We report a systematic study on the construction of the explicit, general form of vortex-surface fields (VSFs) and Clebsch potentials in the initial fields with the zero helicity density and high symmetry. The construction methodology is based on finding independent first integrals of the characteristic equation of a given three-dimensional velocity–vorticity field. In particular, we derive the analytical VSFs and Clebsch potentials for the initial field with the Kida–Pelz symmetry. These analytical results can be useful for the evolution of VSFs to study vortical structures in transitional flows. Moreover, the generality of the construction method is discussed with the synthetic initial fields and the initial Taylor–Green field with multiple wavenumbers.
Effective Hamiltonian for surface states of topological insulator thin films with hexagonal warping
Authors: Siu Zhuo Bin , Tan Seng Ghee , Jalil Mansoor B. A.
Published: March 2016

The effective Hamiltonian of the surface states on semi-infinite slabs of the topological insulators (TI) Bi2Te3 and Bi2Se3 require the addition of a cubic momentum hexagonal warping term on top of the usual Dirac fermion Hamiltonian in order to reproduce the experimentally measured constant energy contours at intermediate values of Fermi energy. In this work, we derive the effective Hamiltonian for the surface states of a Bi2Se3 thin film incorporating the corresponding hexagonal warping terms. We then calculate the dispersion relation of the effective Hamiltonian and show that the hexagonal warping leads distorts the equal energy contours from the circular cross sections of the Dirac cones.
Low-energy mass-selected ion beam production of fragments produced from hexamethyldisilane for SiC film formation
Authors: Yoshimura Satoru , Sugimoto Satoshi , Kiuchi Masato
Published: March 2016

We have proposed an experimental methodology which makes it possible to deposit silicon carbide (SiC) films on Si substrates with a low-energy mass-selected ion beam system using hexamethyldisilane (HMD) as a gas source. In this study, one of the fragment ions produced from HMD, SiCH4+, was mass-selected. The ion energy was approximately 100 eV. Then, the SiCH4+ ions were irradiated to a Si(100) substrate. When the temperature of the Si substrate was set at 800 °C during the ion irradiation, the X-ray diffraction and Raman spectroscopy of the substrate following the completion of ion irradiation experiment demonstrated the occurrence of 3C-SiC deposition.
Effects of annealing and pulse plating on soft magnetic properties of electroplated Fe-Ni films
Authors: Yanai T. , Azuma K. , Eguchi K. , Watanabe Y. , Ohgai T. , Nakano M. , Fukunaga H.
Published: March 2016

We have already reported that Fe-Ni films prepared in citric-acid-based plating baths show good soft magnetic properties. In this paper, we investigated the effect of the grain size of the Fe-Ni crystalline phase in the films on magnetic properties, and employed an annealing and a pulse plating method in order to vary the grain size. The coercivity of the annealed Fe-Ni films at 600 °C shows large value, and good correlation between the grain growth and the coercivity was observed. The pulse plating enables us to reduce the grain size of the as-plated Fe-Ni films compared with the DC plating method, and we realized smooth surface and low coercivity of the Fe-Ni films using the pulse plating method. From these results, we confirmed the importance of the reduction in the grain size, and concluded that a pulse plating is an effective method to improve the good soft magnetic properties for our previously-reported Fe-Ni films.
Soft-release versus hard-release for reintroduction of an endangered species: an experimental comparison using eastern barred bandicoots (Perameles gunnii)
Authors: de Milliano Jasmine , Di Stefano Julian , Courtney Peter , Temple-Smith Peter , Coulson Graeme
Published: March 2016

Context Reintroduction is a popular tool for conserving endangered species, yet many attempts fail. Soft-release measures, including acclimatisation, have been used for many species around the world, based on the reasoning that gradual and supported reintroductions should improve the success of animals released into an unfamiliar wild environment. However, experimental testing of soft-release methods is rare. Aims To experimentally test the effect of a soft-release method versus a hard-release method on the initial reintroduction success of the eastern barred bandicoot (Perameles gunnii). Methods We released 12 captive-bred eastern barred bandicoots into a predator-proof reserve using two methods: soft-release (7 days of on-site acclimatisation with supplementary food before release) and hard-release (no acclimatisation and no supplementary food). We monitored the bandicoots intensively via radio-tracking and live-trapping for 4 weeks after release. Compared with hard-release bandicoots, we predicted that soft-release bandicoots would have (1) reduced movement (first night dispersal, site fidelity and activity range), (2) more directed patterns of habitat selection, (3) improved bodyweights and (4) improved survival. Key results There was no detectable difference in habitat selection, overall weight change and survival between the soft-release and hard-release groups. There was moderate evidence that, compared with the hard-release group, soft-release bandicoots moved less, demonstrated lower individual variation in all measures of movement, and lost weight more gradually after release. In most cases, effect sizes were moderate to large but had large standard errors owing to both small sample size and high variance. Consequently, statistical testing failed to detect significant differences at the 5% level. Conclusions Despite evidence that the release method influenced some of the monitored behaviours, soft-release did not confer a consistent and substantive advantage for captive-bred eastern barred bandicoots at our site. We conclude that soft-release is unlikely to improve overall reintroduction success for this species at fenced predator-free sites. Implications The present study suggests that the preferred option for reintroductions of eastern barred bandicoots to fenced sites is a hard-release, information that is now being used to guide reintroductions of this species. Similar experiments should be undertaken to improve reintroduction practice for other endangered species.
Western grey kangaroos (Macropus fuliginosus) include fauna underpasses in their home range
Authors: Chachelle Paul D. , Chambers Brian K. , Bencini Roberta , Maloney Shane K.
Published: March 2016

Context The presence of large mammals on roads poses a serious risk to both the animals and motorists if collisions with vehicles occur. Fencing roads can reduce this risk, and it also limits the landscape-scale movements of animals. By also constructing fauna underpasses it may be possible to avoid collisions with vehicles, while, at the same time, allowing the natural movement of animals across the landscape. Aims We aimed to determine whether western grey kangaroos (Macropus fulignosus) would use fauna underpasses and to determine how this may affect their home range. Methods We used motion-activated infrared cameras to monitor the use of one large 8 × 3 m arched underpass and two 0.9-m-diameter fauna underpasses over 342 days between March 2011 and March 2012. The underpasses were situated between reserves separated by a four-lane fenced highway, with one reserve surrounded by residential properties. At the same time, 20 kangaroos (10 males and 10 females) were radio-tracked to determine the size of their home range and to test whether the animals incorporated the fauna underpasses into their daily movements. Key results The large fauna underpass was used 3116 times by individual kangaroos in groups of up to 21 animals, whereas the two smaller underpasses were used only twice. In total, 14 of the 20 radio-collared kangaroos used the large underpass over the course of the study, but underpass use did not affect home-range size. Kangaroos that did not use the underpass had a significantly higher proportion of their home range on residential properties surrounding one of the reserves than did those kangaroos that used the underpass. Conclusions The use of the underpass did not affect the size of the home range of the kangaroos, but it allowed the kangaroos to access grazing areas that would have been otherwise inaccessible. Fauna underpasses allow the safe passage of kangaroos between isolated remnant vegetation patches and may reduce significantly the risks posed to motorists and kangaroos from collisions. Implications Fencing roads and constructing fauna underpasses is a viable solution to reducing some of the problems of managing large kangaroos in peri-urban areas.
Doing gender activism in a donor-organized framework: Constraints and opportunities in Kyrgyzstan
Authors: Hoare Joanna Pares
Published: March 2016

Providing support to “civil society” in the form of funding to non-governmental organizations (NGOs) became a central aspect of development engagement in Kyrgyzstan and other post-socialist countries in the 1990s, seen as a means of ensuring “good governance,” promoting participation, and providing a safety net of sorts to those who were left vulnerable by the market reforms that followed the collapse of Communism. Since then, donor engagement in Kyrgyzstan has led to the development of a thriving NGO sector, taken to embody “civil society” and to be a sign of the country's democratization, in comparison to its neighbors. However, this sector is dependent on support from international donors, and faces increasing hostility for supposedly representing outside interests, rather than effectively addressing the needs of the Kyrgyzstani population. This is particularly the case in regard to work on women's rights and gender equality. Based on interviews with 16 self-described activists working on gender issues, this paper explores what it is like to “do” gender activism in this practical and discursive environment. For my respondents, activity in the NGO sector emerges as not only a process that goes far beyond the straightforward implementation of donor agendas, but also one that does not necessarily “fit” with dominant understandings of what constitutes civil society activism.
Fashioning the nation: Gender and politics of dress in contemporary Kyrgyzstan
Authors: Suyarkulova Mohira
Published: March 2016

This article investigates gendered nationalist ideologies and their attendant myths and narratives in present-day Kyrgyzstan through an investigation of clothing items and practices. Clothes “speak volumes,” revealing tensions between gendered narratives of nationhood and various interpretations of what “proper” Kyrgyz femininities and masculinities should be. Clothing thus becomes both a sign and a site of the politics of identity, inscribing power relations and individual strategies of Kyrgyz men and women onto their bodies. Individual clothing choices and strategies take place within the general context of discursive struggles over what authentic and appropriate representations of Kyrgyzness should be. Thus, such clothing items as ak kalpak (conical felt hats) and the practice of Muslim women covering their head (hijab) acquire social and political meanings that stand for wider processes of identity contestations in the country.

Helping motivation and well-being of chronic pain couples: a daily diary study

Published: March 2016

Receiving support from a romantic partner may yield benefits for individuals with chronic pain (ICPs), but may also carry unintended side effects. The conditions under which partner support provision yields (mal)adaptive effects deserve greater attention. Grounded in Self-determination theory, partners may provide help for autonomous or volitional (eg, enjoyment, full commitment) or rather controlled or pressured (eg, avoiding guilt and criticism) motives. This study examined associations between day-to-day fluctuations in partners' type of helping motivation and several outcomes, among partners and ICPs. Seventy couples, with 1 partner having chronic pain (75.7% female), completed a diary for 14 consecutive days. Daily helping motivation was assessed together with daily affect, relational conflict, and relationship-based need satisfaction. Partners (Mage = 55.14) additionally reported on daily helping exhaustion, whereas ICPs (Mage = 54.71) reported on daily pain intensity, disability, satisfaction with received help, and amount of received help. Providing autonomous help related to improvements in partners' affective (eg, positive affect), relational (eg, conflict), and help-specific (eg, exhaustion) functioning, which were accounted for by improvements in daily relationship-based psychological need satisfaction. Similarly, daily autonomously motivated help yielded a direct (ie, relational conflict; perceived amount of help) or indirect (ie, positive and negative affects; relational conflict; satisfaction with help, disability) contribution in explaining ICP outcomes—through improvements in ICPs' relationship-based psychological need satisfaction. Findings highlight the importance of a motivational and dynamic perspective on help provision within chronic pain couples. Considering reasons why a partner provides help is important to understand when partners and ICPs may benefit from daily support.

Gabapentin is prescribed for analgesia in chronic low back pain, yet there are no controlled trials supporting this practice. This randomized, 2-arm, 12-week, parallel group study compared gabapentin (forced titration up to 3600 mg daily) with inert placebo. The primary efficacy measure was change in pain intensity from baseline to the last week on treatment measured by the Descriptor Differential Scale; the secondary outcome was disability (Oswestry Disability Index). The intention-to-treat analysis comprised 108 randomized patients with chronic back pain (daily pain for ≥6 months) whose pain did (43%) or did not radiate into the lower extremity. Random effects regression models which did not impute missing scores were used to analyze outcome data. Pain intensity decreased significantly over time (P < 0.0001) with subjects on gabapentin or placebo, reporting reductions of about 30% from baseline, but did not differ significantly between groups (P = 0.423). The same results pertained for disability scores. In responder analyses of those who completed 12 weeks (N = 72), the proportion reporting at least 30% or 50% reduction in pain intensity, or at least “Minimal Improvement” on the Physician Clinical Global Impression of Change did not differ significantly between groups. There were no significant differences in analgesia between participants with radiating (n = 46) and nonradiating (n = 62) pain either within or between treatment arms. There was no significant correlation between gabapentin plasma concentration and pain intensity. Gabapentin appears to be ineffective for analgesia in chronic low back pain with or without a radiating component.
Agonist-dependence of functional properties for common nonsynonymous variants of human transient receptor potential vanilloid 1
Authors: Wang Sen , Joseph John , Diatchenko Luda , Ro Jin Y. , Chung Man-Kyo

Transient receptor potential vanilloid 1 (TRPV1) is a polymodal receptor activated by capsaicin, heat, and acid, which plays critical roles in thermosensation and pain. In addition, TRPV1 also contributes to multiple pathophysiological states in respiratory, cardiovascular, metabolic, and renal systems. These contributions are further supported by evidence that variations in the human TRPV1 (hTRPV1) gene are associated with various physiological and pathological phenotypes. However, it is not well understood how the variations in hTRPV1 affect channel functions. In this study, we examined functional consequences of amino acid variations of hTRPV1 induced by 5 nonsynonymous single-nucleotide polymorphisms (SNPs) that most commonly exist in the human population. Using electrophysiological assays in HEK293 cells, we examined 9 parameters: activation, Ca2+ permeation, and desensitization after activation by capsaicin, acid, and heat. Our results demonstrated that the 5 SNPs differentially affected functional properties of hTRPV1 in an agonist-dependent manner. Based upon the directionality of change of each phenotype and cumulative changes in each SNP, we classified the 5 SNPs into 3 presumptive functional categories: gain of function (hTRPV1 Q85R, P91S, and T469I), loss of function (I585V), and mixed (M315I). These results reveal a spectrum of functional variation among common hTRPV1 polymorphisms in humans and may aid mechanistic interpretation of phenotypes associated with nonsynonymous hTRPV1 SNPs under pathophysiological conditions.

Published: March 2016

Effective teamwork is essential to foster patient safety and promote quality patient care. Students may have limited to no exposure to interprofessional education (IPE) or collaborative practice, therefore making it challenging to learn how to work in teams. This article describes how a nursing and a medical school collaborated to systematically integrate IPE simulations into the curricula so that every graduate from the respective schools received TeamSTEPPS® education and participated in a standardized IPE simulation experience.

Laryngeal squamous cell carcinoma (LSCC) is one of the most common and aggressive malignancies in the upper digestive tract that has a high mortality rate and a poor prognosis. Prognostic factors were determined through multivariate Cox regression analysis. The overall survival rates were calculated by the Kaplan-Meier method. The SPSS statistical software package version 17.0 (SPSS Inc., Chicago, IL, USA) was used for all analyses. Median follow-up was 38 (range 3-122) months and the median survival time was 48 months. We adjusted to confounding factors (total laryngectomy, poor differentiation, T3-T4 stage, N1-N2 stage, III-IV TNM stage) into multivariate Cox proportional hazards model, we confirmed rs11903757 GT genotype (HR = 2.036; 95% CI, 1.071 - 3.872; p = 0.030) and rs966423 TT genotype (HR = 11.677; 95% CI, 3.901 - 34.950; p = 0.000) were significantly correlated with prognostic survival of patients with LSCC compared with rs11903757 TT genotype and rs966423 CC genotype, respectively. Our research provided new evidence for patients with LSCC, it seemed to be the first that demonstrated rs11903757 GT genotype on chromosome 2q32.3 close toNABP1and rs966423 TT genotype in the intron region ofDIRC3on chromosome 2q35 predict poor prognostic survival in patients with LSCC.

Critical influence of relational governance on relationship value in strategic supply management
Authors: Yeh Ying-Pin
Published: March 2016

Purpose

This paper aims to explore the enhancement of value-added characteristics in strategic supply management by considering manufacturers’ willingness, opinions on relational governance and the effect of relational governance on relationship value.

Design/methodology/approach

After a literature review, this study identified the antecedents of relational governance affecting manufacturers, and explored the effect of relational governance on relationship value, taking relationship quality and interfirm learning as the intervening constructs. Data collected from 259 valid questionnaires completed by purchasing managers for the top 2,000 Taiwanese manufacturers were assessed using a structural equation model.

Findings

The results indicated that relational governance is directly and positively correlated with relationship quality and interfirm learning; relational quality and interfirm learning are directly and positively correlated with relationship value; and consumer orientation and management innovation are directly and positively correlated with relational governance.

Research limitations/implications

The high explanatory power of the results of the deduced model in this research helps to explain the relational governance of manufacturers toward the suppliers. However, the factors affecting the sustainability of cooperative relationships in service contexts might differ.

Practical implications

Relational governance complements the adaptive limits of contracts by fostering the continuance of exchange and entrusting both parties with mutually agreeable outcomes. Relational governance affects manufacturers’ ability to flexibly adapt and overcome uncertainty in the supply chain relationship.

Originality/value

This study investigated the relationship among governance features that support interorganizational relations and developed precise measures of relational governance. The effect of relational governance on the evaluation of relationship value was examined.
Is innovation research contingent on competitive context?
Authors: Pehrsson Tobias
Published: March 2016

Purpose

The purpose of this paper is to extend the understanding of innovation research and its contextual boundaries.

Design/methodology/approach

The paper opts for a systematic review of literature on innovation. Based on research in the agricultural and forest industries, it analyzes differences between research conducted in a competitive context of strong rivalry and research in a context characterized by strong buyer power. In particular, the review compares types of innovation under investigation and the level at which the innovation occurs.

Findings

It was found that competitive context significantly separates the type of innovation under investigation and innovation at different levels. Thus, the findings provide insights on the importance of competitive context to innovation research.

Research limitations/implications

The findings have implications for the understanding of the sources and directions of innovation, and the formation of innovation at the firm and industry levels. The review also provides a relevant foundation for further research.

Practical implications

The review provides a ground for managerial decision-making regarding innovation. A manager wishing to innovate is advised to evaluate the competitive context. The evaluation is crucial, as the context facilitates different types and levels of innovation.

Originality/value

The review is unique in its emphasis that reviewing studies of innovation requires the consideration of competitive context.
