An inverse coefficient problem for a quasilinear parabolic equation with periodic boundary and integral overdetermination condition
Authors:
Publisher and Date:(Wiley-Blackwell, 2015)In this paper the inverse problem of finding the time-dependent coefficient of heat capacity together with the solution periodic boundary and integral overdetermination conditions is considered. Under some natural regularity and consistency conditions on the input data the existence uniqueness and continuous dependence upon the data of the solution are shown. Some considerations on the numerical solution for this inverse problem are presented with an example. Copyright (c) 2014 John Wiley & Sons Ltd.

Cis-cyclopropylamines as mechanism-based inhibitors of monoamine oxidases
Authors:
Publisher and Date:(Wiley-Blackwell, 2015)Cyclopropylamines inhibitors of monoamine oxidases (MAO) and lysine-specific demethylase (LSD1) provide a useful structural scaffold for the design of mechanism-based inhibitors for treatment of depression and cancer. For new compounds with the less common cis relationship and with an alkoxy substituent at the 2-position of the cyclopropyl ring the apparent affinity determined from docking experiments revealed little difference between the enantiomers. Using the racemate kinetic parameters for the ...

Compressive sensing for ultra-wideband channel estimation: on the sparsity assumption of ultra-wideband channels
Authors:
Publisher and Date:(Wiley-Blackwell, 2014)Due to the sparse structure of ultra-wideband (UWB) multipath channels there has been a considerable amount of interest in applying the compressive sensing (CS) theory to UWB channel estimation. The main consideration of the related studies is to propose different implementations of the CS theory for the estimation of UWB channels which are assumed to be sparse. In this study we investigate the suitability of standardized UWB channel models to be used with the CS theory. In other words we question ...

Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
Authors:
Publisher and Date:(Wiley-Blackwell, 2008)In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform a frequency selective fading channel into multiple flat fading subchannels on which first space-frequency coding and then additional space-time coding are applied resulting in a space-time-frequency OFDM (STF-OFDM) scheme. This scheme provides a quasi-orthogonal 4 x 4 ...

Investigation of Drying of Poly(N-isoproplacrylamide-co-acrylamide) by Fluorescence Technique
Authors:
Publisher and Date:(Wiley-Blackwell, 2013)The steady-state fluorescence technique was performed on drying of various molar percentages of poly(N-isopropylacrylamide-co- acrylamide) [poly(NIPA-co-AAc)] to elucidate the mechanism of temperature-induced phase separation and the effect of monomer content. Poly(NIPA-co-AAc) copolymers were prepared by free radical cross-linking copolymerization. The fluorescence intensity I of pyranine introduced as a probe increased as drying time was increased for all samples. The behavior of I was modeled ...

Making transnational publics: Circuits of censorship and technologies of publicity in Kurdish media circulation
Authors:
Publisher and Date:(Wiley-Blackwell, 2013)Kurdish media producers who interweave social and political agendas with their filmmaking are often marginalized within Turkish media worlds. Impeded by national censorship these filmmakers move between national and transnational media worlds to advance their cinematic work. Such movement helps them create and maintain transnational publics that reinforce circulation of their media texts. Here I analyze how a documentary film about a seminomadic Kurdish community moves through international screening ...

Relative group size and minority school success: The role of intergroup friendship and discrimination experiences
Authors:
Publisher and Date:(Wiley-Blackwell, 2014)From an intergroup relations perspective relative group size is associated with the quantity and quality of intergroup contact: more positive contact (i.e. intergroup friendship) supports and negative contact (i.e. experienced discrimination) hampers minority identity and school success. Accordingly we examined intergroup contact as the process through which perceived relative proportions of minority and majority students in school affected minority success (i.e. school performance satisfaction ...
