Identification and Characterization of Membrane Proteins from Mouse Brain Tissue

According to recent published studies, membrane proteins are the most attractive targets in proteomics research. It is estimated that, approximately 30% of proteins encoded by the mammalian genome are transmembrane proteins [1,2]. These proteins participate in a variety of cellular processes such as cell adhesion, immuno-protection, metabolism and signal transduction [3]. Differential expression of membrane proteins can be the main cause of pathological states such as: Alzheimer’s disease, diabetes, Hodgkin’s disease and liver cirrhosis [4]. Membrane proteins are the usual candidates for drug development (about 60% of approved drugs target membrane proteins) due to their roles as transporters, receptors and structural proteins as well as their impacts on intracellular processes [5]. Therefore, the study of membrane proteins holds promises not only for the understanding of disease mechanism but also for the search of new biomarkers that can be the targets for the drug development.

H0LiCOW - IV. Lens mass model of HE 0435-1223 and blind measurement of its time-delay distance for cosmology

Strong gravitational lenses with measured time delays between the multiple images allow a direct measurement of the time-delay distance to the lens, and thus a measure of cosmological parameters, particularly the Hubble constant, H-0. We present a blind lens model analysis of the quadruply imaged quasar lens HE 0435-1223 using deep Hubble Space Telescope imaging, updated time-delay measurements from the COSmological MOnitoring of GRAvItational Lenses (COSMOGRAIL), a measurement of the velocity dispersion of the lens galaxy based on Keck data, and a characterization of the mass distribution along the line of sight. HE 0435-1223 is the third lens analysed as a part of the H-0 Lenses in COSMOGRAIL's Wellspring (HOLiCOW) project. We account for various sources of systematic uncertainty, including the detailed treatment of nearby perturbers, the parametrization of the galaxy light and mass profile, and the regions used for lens modelling. We constrain the effective time delay distance to be D-Delta t = 2612(191)(+208) Mpc, a precision of 7.6 per cent. From HE 0435-1223 alone, we infer a Hubble constant of H-0 = 73.1(6.0)(+5.7) km s(-1) Mpc(-1) assuming a flat ACDM cosmology. The cosmographic inference based on the three lenses analysed by HOLiCOW to date is presented in a companion paper (HOLiCOW Paper V).
Bounds for Jacobian of harmonic injective mappings in n-dimensional space

Using normal family arguments, we show that the degree of the first nonzero homogenous polynomial in the expansion of $n$ dimensional Euclidean harmonic $K$-quasiconformal mapping around an internal point is odd, and that such a map from the unit ball onto a bounded convex domain, with $K< 3^{n-1}$, is co-Lipschitz. Also some generalizations of this result are given, as well as a generalization of Heinz's lemma for harmonic quasiconformal maps in $\mathbb R^n$ and related results.
TWO NEW HYBRID DENDROICA WARBLERS AND NEW METHODOLOGY FOR INFERRING PARENTAL SPECIES

ABsTRAcr. -A phenotypic hybrid between Dendroica townsendi x D. nigrescens is described from coastal British Columbia. It carried the mitochondrial-DNA (mtDNA) haplotype of nigrescens, indicating a nigrescens mother in the original cross that led to this hybrid. This specimen is used to demonstrate the special value of "contradictory characters" in refuting alternate hypotheses of parentage for hybrids. Contradictory characters exist when a potential hybrid exhibits character states more extreme than those found in both of a possible pair of parents. While intermediate characters can suggest a hybrid ancestry, intermediate character states may also be consistent with a variety of potential pairs of species as parents, a point I demonstrate using this townsendi x nigrescens hybrid. Phenotypically, the second specimen is a typical townsendi, but its mtDNA haplotype was that of virens. An extensive survey of townsendi haplotypes revealed no other polymorphism for the virens haplotype; furthermore, at least four mutations would be required to move from a townsendi to a virens haplotype. Together these observations suggest that this specimen is a highly backcrossed descendent of a townsendi x virens cross, a hypothesis consistent with the fact that this specimen was collected where the ranges of townsendi and virens very nearly make contact in the Rocky Mountains of British Columbia.

Discrete complex analysis – the medial graph approach

We discuss a new formulation of the linear theory of discrete complex analysis on planar quad-graphs based on their medial graphs. It generalizes the theory on rhombic quad-graphs developed by Duffin, Mercat, Kenyon, Chelkak and Smirnov and follows the approach on general quad-graphs proposed by Mercat. We provide discrete counterparts of the most fundamental objects in complex analysis such as holomorphic functions, differential forms, derivatives, and the Laplacian. Also, we discuss discrete versions of important fundamental theorems such as Green’s identities and Cauchy’s integral formulae. For the first time, Green’s first identity and Cauchy’s integral formula for the derivative of a holomorphic function are discretized. 1. History Discrete harmonic functions on the square lattice were studied by a number of authors in the 1920s, including Courant, Friedrichs, and Lewy [5]. Discrete holomorphic functions on the square lattice were studied by Isaacs [10]. He proposed two different definitions for holomorphicity. One of them was reintroduced and further investigated by Lelong-Ferrand [8]. She developed the theory to a level that allowed her to prove the Riemann mapping theorem using discrete methods [13]. Duffin also studied discrete complex analysis on the square grid [6], and he was the first who extended the theory to rhombic lattices [7]. Kenyon [12], and Chelkak and Smirnov [3] resumed the investigation of discrete complex analysis on rhombic lattices, or, equivalently, isoradial graphs. Mercat extended the theory from domains in the complex plane to discrete Riemann surfaces, first considering cellular decompostions into rhombi [14] and later generalizing the notions to general quadrilaterals [16]. The motivation for this theory of discrete Riemann surfaces is derived from statistical physics, in particular, the Ising model. Mercat defined a discrete Dirac operator and discrete spin structures, and he identifies criticality in the Ising model with rhombic quadgraphs. Some two-dimensional discrete models in statistical physics exhibit conformally invariant properties in the thermodynamical limit. Such conformally invariant properties were established by Chelkak and Smirnov for the Ising model [4], and by Kenyon for the dimer model on a square grid [11]. In both cases, linear theories of discrete analytic functions on regular grids were highly important. Kenyon, Chelkak and Smirnov obtained important analytic results [12, 3], which were instrumental in the proof that the critical Ising model is universal [4]. Important non-linear discrete theories of complex analysis involve circle packings, or, more generally, circle patterns. Rodin and Sullivan first proved that the Riemann mapping of a complex domain to the unit disk can be approximated by circle packings [17].

Relating Corroded Seven-Strand, Posttensioned Cable Cross-Sectional Properties to Load Capacity

Multistrand anchors have seen widespread use, providing strength and stability at hydraulic Corps facilities. However, these steel tendons are subject to strength reduction as an effect of corrosion. Methods for evaluating the corroded cable strength do not exist to accurately estimate the time until tendon cables would have to be replaced (at great expense). The following five research tasks are used to address this deficiency: laboratory accelerated corrosion; pull-tests on pristine and laboratory corroded cables; optical scanning; data collection correlated with cross-sectional properties of cables; and development of a method to relate this data to the field. The pull-tests provide measured capacities for seven-strand, posttensioned (PT) cables. An optical scan of the corroded cables provides cross-sectional properties of individual wires within the pulled cables. Trendlines are established for the related peak cable capacities and cross-sectional properties in an effort to determine their correlations. Trendlines for minimum wire area and second-moment short axis diameter are found with low error, making them good predictors of loaded cable capacity. This pull-test dataset has been related back to cable failure in the field, assuming a linear rate of corrosion loss for the cross-sectional properties and required PT capacity.
The Effect of Social Transparency on Firm Value and Performance: Evidence from Firms Listed in Tehran Stock Exchange

In this study, the impact of social transparency on the firm value and performance of companies listed in Tehran stock exchange (TSE), based on data from 101 companies in year of 2015 is examined. To do this, two main hypotheses and two sub-hypotheses were specified. The statistical method used in testing hypotheses is panel data regression. Findings show that social transparency is positively associated with firm Value and Performance. Overall, the results suggest that social transparency plays an important role in firm value and performance. This paper will help the management to develop effective social responsibility policies required to achieve better financial performance in long-term and provide awareness for firms in the field of role of social responsibility of firms to achieve future benefits.
Correlation and Spiral Microscopy using a Spatial Light Modulation

The doctoral thesis presents a review of the main research results obtained in the course of doctoral studies. In the introductory part, the motivation and technical support for the planned research are discussed in connection with research activities of the group of Experimental Biophotonics at the Institute of Physical Engineering, Brno University of Technology. The scientific part of the doctoral thesis is divided into two main parts devoted to new imaging concepts and modifications of current experiments to extend their application potential. Achieved results support the research development in the areas of correlation and spiral microscopy, utilizing a spatial light modulation as a key experimental technique. Among the new imaging concepts, the correlation imaging is examined under conditions of partial spatial and temporal coherence of light. Subsequently, the principles of singular optics and nondiffracting propagation of light are advantageously implemented in correlation, holographic and optical microscopy, resulting in advanced imaging techniques and holographic reconstructions. Specifically, the vortex and nondiffracting beams and the self-imaging effects are successfully deployed using either optical or digital tools and gradually applied to 3D spiral imaging ensuring the edge contrast enhancement or axial localization of microobjects by the rotating point spread function. The results obtained by the theoretical analysis and the experimental testing of the proposed imaging modalities are also presented. In the technical part of the doctoral thesis, up-to-date imaging configurations aided by a spatial light modulator are optimized, allowing the wide-field correlation imaging and achromatic high-resolution imaging by a programmable diffractive lens. In the correlation imaging, the enhanced field of view is achieved by deploying a relay optical system in standard experiments, while achromatic correction of diffractive lenses is implemented by a specially designed refractive corrector. Using birefringence of liquid crystal molecules of light modulating devices, a new phase-shifting technique is proposed and tested in polarization adapted Mirau interferometer. Acquired experimental know-how is fully exploited in the design of multimodal microscope working with different imaging modes implemented using an add-on module connected to standard microscope.
An evaluation of secondary school principals’ perception of learning resources in free secondary education era in Kenya

This article reports on the findings from a quantitative research study on learning resources in Kenya’s secondary schools. The purpose of this study is to investigate the secondary school principals’ perception on the learning resources. The study adopted a quantitative survey design involving 81 secondary principals, selected purposively. Data was collected using a questionnaire (open and closed-ended, rating scale items). Data was analysed using Statistical Package for Social Sciences (SPSS) resulting in descriptive data. From the study, it was found that some schools do not have laboratories, libraries and workshops. Some of the resources were charged unfavourably by the principals therefore raising concerns regarding their quality in the teaching learning process. In terms of their contributions to the teaching and learning process, textbooks and classrooms were charged higher while furniture was charged lowest. The rest of the resources fall in between. As sources of funding, Secondary Free Education (FSE) and Parent Teacher Association (PTA) were considered favourably than Constituency Development Fund (CDF) and Local Authority Transfer funds (LATF). However, FSE was found to be inadequate and unreliable. In conclusion, the implications of the principals’ perception on the quality of the teaching and learning resources are that their morale and job satisfaction may be negatively affected thus indirectly affecting the quality of teaching and learning. Poor quality of resources would directly affect the teaching and learning process. In either case, students’ attainment may be affected negatively.
Faye Abdellah Model to Banishing Social Stigma of Head Lice Among School Students

In this paper, an experimental comparative study was carried out aiming to monitor the effect of Faye Abdellah Theory Model on banishing social stigma of head lice among school students and monitor its effect on their health status and self-esteem. For the study purpose a sample of convenience of 1600 school students and their mothers was recruited from 16 schools from both countries participated in the study. Four tools used, pre/post interviewing questionnaire, observation checklists, Faye Abdellah model format, self-esteem scale sheet and students/mothers guidance booklet. The results showed that the total numbers of students at 8 schools in Egypt were 800/16700, with prevalence ratio 20.8% and 800/14300 from Kingdom of Saudia Arabia with the prevalence ratio 17.8%. The study documented that there is highly significant effects of the model on students’ health status and banishing the social stigma and there is a highly positive association between self-esteem and assurance to the health behavior. It concluded that highly self-esteem had excellent health status and completely confident in coping with self-care management. And it is recommended that knowledge is power and teaching mothers and students about head lice myths and facts is key to demystifying the stigma.
I saw the real Father Christmas! Children's everyday uses of the words real, really, and pretend

The words real, really and pretend are used in developmental research paradigms to reflect both the notions of ‘authenticity’ (in pretense-reality and appearance-reality research) and ‘existence’ (in fantasy-reality research). The current study explored whether children also expressed these notions in their everyday uses of real, really, and pretend. Mothers were interviewed and kept diary records, resulting in data for a younger group of children (2- to 3-year-olds, N ¼ 80) and an older group (4- to 7-yearolds, N ¼ 101). Utterances were analysed according to different uses of the target words and the topic of conversation in which they occurred. The words real, really, and pretend were used by both the younger and older age groups predominantly to consider the authenticity of things around them. Expression of the notion of existence was less common, particularly among the younger children. The implications of these findings are discussed in relation to children’s performance in experimental studies, particularly those that intend to question children’s understanding of the fantasy-reality distinction. Learning about the reality or otherwise of objects, people, and events in the world is an important cognitive task (Woolley & Wellman, 1990). The current study focuses on two aspects of reality, both of which can be discussed using the words real, really, and pretend. The first refers to the notion of ‘authenticity’ and is the aspect of meaning considered in pretense-reality and appearance-reality distinctions. In a pretense episode used by Harris, Kavanaugh, and Meredith (1994, Experiment 3), for example, children were shown a scene in which cotton wool was used to represent milk. The critical question was whether children thought that the cotton wool was ‘real or pretend’ milk and what it ‘reallywas’. Similarly,Rosen, Schwebel, and Singer (1997)asked the children who were shown a televised episode of ‘Barney’: ‘Is everyone on Barney really cleaning up or are they just pretending to clean up? ’ In appearance-reality studies, children are shown an object, e.g. a sponge, that looks like something else, a rock, and then they are asked whether the sponge is really a rock or really a sponge (Flavell, Green, & Flavell, 1986). Thus,in pretense-realityand appearance-reality contrasts, childrenhavetodecide whether an object or action is, in some way, an ‘authentic’ version or not.
Opening and Closing Price Efficiency: Do Financial Markets Need the Call Auction?

We model 73.62 million London Stock Exchange (LSE) trades and show that the LSE's high rate of failure to open at the opening auction only relates to low volume stocks. Low volume stock traders avoid trading until the open; this seems connected to their evading the informed trading-dominated opening auction. For the largest volume stocks, the opening auction provides highly efficient opening prices, while the lower volume stocks attain similar levels of price efficiency only after the start of normal trading hours (NTH). At the close however, all stocks only lose small fractions of informational efficiency achieved during the NTH.
Tourism Specialization, Absorptive Capacity, and Economic Growth

This article investigates the relationship between tourism specialization and economic growth while accounting for the absorptive capacity of host (tourism destination) countries, defined in terms of financial system development. We use the system generalized methods-of-moments (SYS-GMM) estimation methodology to investigate this relationship for 129 countries over the period 1995–2011. The results support the hypothesis that the positive effect of tourism specialization on growth is contingent on the level of economic development as well as the financial system absorptive capacity of recipient economies. Consistent with the law of diminishing returns, we also find that for countries with a developed financial system, at exponential levels of tourism specialization, its effect on growth turns negative. Significant policy implications flow from these findings.
Business risk management-the key success factor: evidence from shebeens and taverns in Soshanghuve Township

This study examined the factors that affect business growth by shebeens and taverns owners in Soshanguve Township. Data were collected using structured close-ended questionnaires. The population consisted of 196 businesses, 120 were sampled and 84 responses were received. Frequency analysis, SEM modelling and Chi-square tests were done to analyze the data. Results indicate that majority of the businesses were operating as sole propriety and have been in existence for more than 5 years, hired less than 5 full time employees. The study revealed that there was a weak but positive relationship between capital, managerial skills, government support, legislation, regulations and the growth of the business, while entrepreneurial capabilities showed a strong, and positive relationship with growth. This study concludes that awareness of business risk; its management, willingness to take risk and expand were the key factors to growth. While other factors listed by literature do play a role in the growth but were not paramount to success.
Investigation of chlorine radical chemistry in the Eyjafjallajökull volcanic plume using observed depletions in non‐methane hydrocarbons

As part of the effort to understand volcanic plume composition and chemistry during the eruption of the Icelandic volcano Eyjafjallajökull, the CARIBIC atmospheric observatory was deployed for three special science flights aboard a Lufthansa passenger aircraft. Measurements made during these flights included the collection of whole air samples, which were analyzed for non‐methane hydrocarbons (NMHCs). Hydrocarbon concentrations in plume samples were found to be reduced to levels below background, with relative depletions characteristic of reaction with chlorine radicals (Cl). Recent observations of halogen oxides in volcanic plumes provide evidence for halogen radical chemistry, but quantitative data for free halogen radical concentrations in volcanic plumes were absent. Here we present the first observation‐based calculations of Cl radical concentrations in volcanic plumes, estimated from observed NMHC depletions. Inferred Cl concentrations were between 1.3 × 104 and 6.6 × 104 Cl cm−3. The relationship between NMHC variability and local lifetimes was used to investigate the ratio between OH and Cl within the plume, with [OH]/[Cl] estimated to be ∼37.
Measurement of the transverse momentum distribution of Z / γ ∗ bosons in proton–proton collisions at √ s = 7 TeV with the ATLAS detector ✩

A measurement of the Z / γ ∗ transverse momentum ( p Z T ) distribution in proton–proton collisions at √ s = 7 TeV is presented using Z / γ ∗ → e + e − and Z / γ ∗ → μ + μ − decays collected with the ATLAS detector in data sets with integrated luminosities of 35 pb − 1 and 40 pb − 1 , respectively. The normalized differential cross sections are measured separately for electron and muon decay channels as well as for their combination up to p Z T of 350 GeV for invariant dilepton masses 66 GeV < m (cid:4)(cid:4) < 116 GeV. The mea- surement is compared to predictions of perturbative QCD and various event generators. The prediction of resummed QCD combined with ﬁxed order perturbative QCD is found to be in good agreement with the data.
