description: We report on localized plasmon assisted scattering supported by Ag nanoprotrusions and Ag nanoparticles located at
the back contact of thin-film silicon solar cells. The interaction of electromagnetic waves with these Ag
nanostructures was simulated with a three-dimensional numerical solver of Maxwell’s equations. Scattering angle
distributions and absorption profiles were calculated from the simulated electric field distribution. In state of the art
μc-Si:H thin-film silicon solar cells, light of wavelengths above 550 nm reaches the back contact. For these
wavelengths, localized plasmons in Ag nanoparticles and Ag nanoprotrusions positioned at the back contact are
found to scatter a large fraction of the incident light to large angles at low optical losses. This way, these Ag
nanostructures can serve as sub-wavelength scattering components which couple incident propagating light into the
silicon absorber layer. Geometrical parameters such as radius of the Ag nanoparticles and Ag nanoprotrusions or
thickness of their embedding dielectric layer (e.g. ZnO) have been optimized.

description: The so-called Atiyah conjecture states that the von Neumann dimensions of the L2-homology modules of free G-CW-complexes belong to a certain set of rational numbers, depending on the finite subgroups of G. In this article we extend this conjecture to a statement for the center-valued dimensions. We show that the conjecture is equivalent to a precise description of the tructure as a semisimple Artinian ring of the division closure D(QG) of Q[G] in the ring of affiliated operators. We prove the conjecture for all groups in Linnell's class C, containing in particular free-by-elementary amenable groups. The center-valued Atiyah conjecture states that the center-valued L2-Betti numbers of finite free G-CW-complexes are contained in a certain discrete subset of the center of C[G], the one generated as an additive group by the center-valued traces of all projections in C[H], where H runs through the finite subgroups of G. Finally, we use the approximation theorem of Knebusch for the center-valued $L^2$-Betti numbers to extend the result to many groups which are residually in C, in particular for finite extensions of products of free groups and of pure braid groups.

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4317-4319
description: The Green islands project aims at the development of an integrated energy plan for Azores islands
based on its natural resources. Since the production of photovoltaic (PV) technology occurs during peak hours
demand, PV seems to be an attractive solution to integrate the energy portfolio of a sustainable island. This paper
evaluates the potential of PV in Azores by modeling PV systems performance in three different system
configurations: conventional flat-plate, 2-axes tracker and a concentration system, the DoubleSun® technology. The
inputs of the model were the local coordinates and the atmospheric conditions, which were recorded during 2009 in
Angra do Heroísmo, in Terceira island, Azores.

description: Additive utility function models are widely used in multiple criteria decision analysis. In such models, a numerical value is associated to each alternative involved in the decision problem. It is computed by aggregating the scores of the alternative on the different criteria of the decision problem. The score of an alternative is determined by a marginal value function that evolves monotonically as a function of the performance of the alternative on this criterion. Determining the shape of the marginals is not easy for a decision maker. It is easier for him/her to make statements such as "alternative $a$ is preferred to $b$". In order to help the decision maker, UTA disaggregation procedures use linear programming to approximate the marginals by piecewise linear functions based only on such statements. In this paper, we propose to infer polynomials and splines instead of piecewise linear functions for the marginals. In this aim, we use semidefinite programming instead of linear programming. We illustrate this new elicitation method and present some experimental results.

description: We investigated the effect of plasma power density on the film properties of intrinsic hydrogenated
amorphous silicon oxide (i-a-SiO:H) layer. The experimental results indicated that the defect density was increased
with the increase in plasma power density. The p-i-n type thin film silicon solar cells using i-a-SiO:H films as an
absorber layer were fabricated on glass substrate in order to investigate the effects of plasma power density of the i-a-
SiO:H deposition and also the i-a-SiO:H thickness on the conversion efficiency (h) of the a-SiO:H based solar cell.
We found that the h was improved from 6.8 to 7.3% due to the improvement in fill factor (FF) by decreasing plasma
power density. By employing an optimal i-a-SiO:H layer with the thickness of 250 nm, the solar cell showed the best
initial efficiency of about 7.7%. Compared with the cell using conventional i-a-Si:H absorber layer, a peak of the
spectra response in the short wavelength region (400-600 nm) was shifted from 600 to 500 nm. These results showed
the potential of the i-a-SiO:H films for using in top cell of multi junction solar cell in order to improve the light
absorption in the short wavelength region.

description: We present a list of galaxy-scale lens candidates including a highly probable interacting galaxy-scale lens in the Hyper Suprime-Cam (HSC) imaging survey. We combine HSC imaging with the blended-spectra catalog from the Galaxy And Mass Assembly (GAMA) survey to identify lens candidates, and use lens mass modeling to confirm the candidates. We find 46 matches between the HSC S14A_0b imaging data release and the GAMA catalog. Ten of them are probable lens systems according to their morphology and redshifts. There is one system with an interacting galaxy pair, HSC J084928+000949, that has a valid mass model. We predict the total mass enclosed by the Einstein radius of $\sim0.72$" ($\sim1.65$kpc) for this new expected lens system to be $\sim10^{10.59}M_{\odot}$. Using the photometry in the {\it grizy} bands of the HSC survey and stellar population synthesis modeling with a Salpeter stellar initial mass function, we estimate the stellar mass within the Einstein radius to be $\sim10^{10.46}\,M_{\odot}$. We thus find a dark matter mass fraction within the Einstein radius of $\sim25\%$. Further spectroscopy or high-resolution imaging would allow confirmation of the nature of these lens candidates. The particular system with the interacting galaxy pair, if confirmed, would provide an opportunity to study the interplay between dark matter and stars as galaxies build up through hierarchical mergers.

title: An exploration of the factors that influence the physical activity promotion practices of healthcare professionals caring for adults with chronic diseases
Creators: name: Forrest, Bruce
Publisher: name: Edinburgh Napier University
Year: 2022

description: Background: Physical activity (PA) benefits physical and mental health and is effective in the prevention and treatment of non-communicable diseases. Globally, one in four adults are insufficiently active to benefit health and levels of physical activity are in decline. Brief behaviour change interventions by healthcare professionals (HCPs) effectively increase patients’ PA, yet levels of promotion by HCPs remain low. Therefore, research in this thesis aims to explore the factors that influence the promotion of physical activity practices by HCPs.

Methods: The research is comprised of three phases – 1) A systematic review of 65 studies, representing 11,236 HCPs from 17 countries, that examines HCPs’ perceptions about what influences promotion of physical activity for adults. 2) A qualitative study using semi-structured interviews that explores the perspectives of 14 HCPs who regularly refer patients to a PA referral scheme about what influences their promotion practices. 3) An explanatory mixed methods study that examines the engagement of pre-registration nursing and physiotherapy students (n=39) with an online physical activity promotion education programme, the resultant change in self-perceived motivational interviewing skills, and programme acceptability.

Results: The systematic review and qualitative study show that HCPs believe that physical activity is beneficial to health and consider promotion of physical activity to be important, but it can be limited due to patient health issues and low motivation. HCPs reported mixed levels of knowledge, education and confidence to promote physical activity. The practice of physical activity promotion was influenced by knowledge about the health benefits of exercise, role-specific perceptions, personal physical activity levels, patient factors, and knowledge and feedback from the referral scheme. In the mixed methods study, 35.7% of those starting the online course completed it, with no significant change in self-perceived motivational interviewing skills. Physiotherapists were significantly more likely to complete the course than nurses (p=0.006). Personal factors, difficulties with the online platform and the Covid-19 pandemic led to dropout.

Conclusion: HCPs consider promotion of physical activity to be important, but there are notable challenges in engaging patients in discussions of physical activity. More HCP education is required to enable effective patient behaviour change.

description: The temporal-difference methods TD($λ$) and Sarsa($λ$) form a core part of modern reinforcement learning. Their appeal comes from their good performance, low computational cost, and their simple interpretation, given by their forward view. Recently, new versions of these methods were introduced, called true online TD($λ$) and true online Sarsa($λ$), respectively (van Seijen & Sutton, 2014). These new versions maintain an exact equivalence with the forward view at all times, whereas the traditional versions only approximate it for small step-sizes. We hypothesize that these true online methods not only have better theoretical properties, but also dominate the regular methods empirically. In this article, we put this hypothesis to the test by performing an extensive empirical comparison. Specifically, we compare the performance of true online TD($λ$)/Sarsa($λ$) with regular TD($λ$)/Sarsa($λ$) on random MRPs, a real-world myoelectric prosthetic arm, and a domain from the Arcade Learning Environment. We use linear function approximation with tabular, binary, and non-binary features. Our results suggest that the true online methods indeed dominate the regular methods. Across all domains/representations the learning speed of the true online methods are often better, but never worse than that of the regular methods. An additional advantage is that no choice between traces has to be made for the true online methods. Besides the empirical results, we provide an in-depth analysis of the theory behind true online temporal-difference learning. In addition, we show that new true online temporal-difference methods can be derived by making changes to the online forward view and then rewriting the update equations.
description: This is the published JMLR version. It is a much improved version. The main changes are: 1) re-structuring of the article; 2) additional analysis on the forward view; 3) empirical comparison of traditional and new forward view; 4) added discussion of other true online papers; 5) updated discussion for non-linear function approximation

Silicon Solar Cell Characterisation and Modelling

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1534-1537
description: Solar cells with an inhomogeneous distribution of high Rser are not well described by the standard I-V curve
model. On such solar cells process optimization for improving the front surface passivation can not be monitored by I-V
curve analysis. Therefore in this paper local CELLO maps are used instead of integral I-V curve data to benchmark different
cleaning procedures. The CELLO technique allows the determination of solar cell parameters (life, Rser, Rshunt) locally and
non-destructively by analyzing the current (dI) or voltage (dU) response of a globally illuminated solar cell (0.3 suns) to a
local perturbation induced with a LASER beam. CELLO Rser maps are used to identify loss areas due to a high Rser and to
dismiss cells where losses are dominated by Rser. CELLO maps taken at the maximum power point (mpp) are used for a
qualitative (and quantitative) analysis of (local and global) efficiency losses. Further defects like surface damages, scratches
or inhomogeneous SiN areas are identified by comparing CELLO power loss maps with optical microscope images. From
dUmpp(x,y)/dIsc(x,y) maps a relative gain of 20 % for optimal cleaning was found.

description: Ga- and Al-doped ZnO (GAZO) films with different Ga content were deposited by magnetron
sputtering to study the effect of Ga doping on structural and optoelectronic characteristics of AZO films. The suitable
Ga doping improved the crystallinity and grain size of AZO films. The resistivity of AZO film was improved from
3.510-3 to 8.110-4 Ω·cm by Ga-doping of 2.1 at. %. Hall mobility was increased by the improvement of
crystallinity and increase in carrier concentration resulted from Ga activation as a donor. Optical bandgap was
increased and transmittance in the visible region was increased from 86.7 to 91.0% by Ga-doping of 2.1 at. %. In
further increase in Ga content exceeding 2.1 at. %, the crystallinity and resistivity of Ga-doped AZO (GAZO) films
was deteriorated. After heat treatment in air, an increasing rate of resistivity of AZO and GAZO film with Ga content
of 2.1 at. % was 36.8 and 12.1%, respectively. The crystallinity of AZO film was deteriorated by chemisorptions of
oxygen from air, whereas that of GAZO films with Ga content above 2.1 at. % was rather improved, which is
attributed to the Ga that resistive to oxidation. The GAZO film with suitable Ga-doping can improve optoelectronic
properties and reliability of resistivity of AZO film.

description: In this paper, we study the impact of aliased out-of-band interference signals on the information sum-rate of the maximum ratio combining receiver in massive multiple-input multiple-output (MIMO) uplink, with both perfect and imperfect channel estimates, in order to determine the required out-of-band attenuation in RF bandpass filters (BPFs). With imperfect channel estimates, our study reveals that as the number of base-station (BS) antennas ($M$) increases, the required attenuation at the BPFs increases as $\mathcal{O}(\sqrt{M})$ with $M \to \infty$, provided the desired information sum-rate (both in the presence and in the absence of AOOBIs (aliased out-of-band interferers)) remains fixed. This implies a practical limit on the number of BS antennas due to the increase in BPF design complexity and power consumption with increasing $M$.

title: Semantic model-driven framework for validating quality requirements of internet of things streaming data
Creators: name: Bamgboye, Oluwaseun O.
Publisher: name: Edinburgh Napier University
Year: 2022

description: The rise of Internet of Things has provided platforms mostly enhanced by real-time data-driven services for reactive services and Smart Cities innovations. However, IoT streaming data are known to be compromised by quality problems, thereby influencing the performance and accuracy of IoT-based reactive services or Smart applications. This research investigates the suitability of the semantic approach for the run-time validation of IoT streaming data for quality problems. To realise this aim, Semantic IoT Streaming Data Validation with its framework (SISDaV) is proposed. The novel approach involves technologies for semantic query and reasoning with semantic rules defined on an established relationship with external data sources with consideration for specific run-time events that can influence the quality of streams. The work specifically targets quality issues relating to inconsistency, plausibility, and incompleteness in IoT streaming data.
In particular, the investigation covers various RDF stream processing and rule-based reasoning techniques and effects of RDF Serialised formats on the reasoning process. The contributions of the work include the hierarchy of IoT data stream quality problem, lightweight evolving Smart Space and Sensor Measurement Ontology, generic time-aware validation rules and, SISDaV framework- a unified semantic rule-based validation system for RDF-based IoT streaming data that combines the popular RDF stream processing the system with generic enhanced time-aware rules.

The semantic validation process ensures the conformance of the raw streaming data value produced by the IoT node(s) with IoT streaming data quality requirements and the expected value. This is facilitated through a set of generic continuous validation rules, which has been realised by extending the popular Jena rule syntax with a time element. The comparative evaluation of SISDaV is based on its effectiveness and efficiency based on the expressivity of the different serialised RDF data formats.

The results are interpreted with relevant statistical estimations and performance metrics. The results from the evaluation approve of the feasibility of the framework in terms of containing the semantic validation process within the interval between reads of sensor nodes as well as provision of additional requirements that can enhance IoT streaming data processing systems which are currently missing in most related state-of-art RDF stream processing systems. Furthermore, the approach can satisfy the main research objectives as identified by the study.

description: Energy yield assessment of photovoltaic systems is inherently non-linear. The calculation chain starts with simulation of solar radiation, where many factors are considered: sun’s position, terrain, properties of the atmosphere and cloudiness to determine the absolute value of global irradiance and the ratio of diffuse and direct components. The ratio of direct and diffuse components influences the global irradiance received by the inclined surface of PV modules, it changes during a day and also during seasons and it is highly dependent on the geographical location. Therefore, optimally multiyear time series should be used for proper modeling of energy performance of a PV generator. However, for historical reasons, several solar radiation data products with different level of simplification are used in PV simulation tools – long-term monthly-averaged daily profiles, synthetic time series, and typical meteorological years (TMYs). A new simplified approach is based on the statistical aggregation of solar radiation into relevant groups (bins) according to distribution of irradiance values. This paper seeks to provide a benchmark for four solar radiation data products used in the contemporary software packages for performance assessment of photovoltaic systems. The results of calculation the in-plane irradiation show different performance of data products, when compared to full time series, with error amplitude up to ±3%.

description: Based on the recently updated Isospin-dependent Boltzmann-Uehling-Uhlenbeck (IBUU) transport model, we studied the effects of symmetry energy on the neutron to proton n/p ratio and the $π^{-}/π^{+}$ ratio in central $^{132}\rm {Sn}+^{124}\rm {Sn}$ reaction at 300 MeV/nucleon. It is found that the n/p ratio and the $π^{-}/π^{+}$ ratio in central $^{132}\rm {Sn}+^{124}\rm {Sn}$ reaction at 300 MeV/nucleon mainly probe the symmetry energy in the density region 1-1.5 times saturation density. However, the $π^{-}/π^{+}$ ratio may be able to probe the density-dependent symmetry energy above 1.5 times saturation density by making some kinematic restrictions such as the azimuthal angle and kinetic energy cuts of emitting pions.

description: Cost reduction is an important element on the way to grid parity. It has been shown that production
costs of thin film modules can be further reduced by introducing new processes in the back end. Six different
contacting technologies were analysed as well as the whole current path in a thin film module, from the first and last
cell to the junction box. The pros and cons of each technology were compared together with their suitability for the
different connections in a thin film module. It was also shown which contacting technology works well for different
back metal materials and different ribbon materials. The same was done for two different sealing technologies.
Finally a cost comparison of different processes was done based on 100 MW thin film production line. It was shown
that for both processes (contacting and sealing) material cost savings of up to 1'000'000 € can be reached.

description: Innerhalb eines Krankenhauses beeinflusst der Radiologe in einem Verbund von Fachabteilungen wesentlich die Liegezeiten von Patienten durch die diagnostische Information und die Verfügbarkeit seiner Dienstleistungen. Die Organisation und zeitliche Bemessung von radiologischen Untersuchungsabläufen werden dadurch um so wichtiger. Der Arzt wird im Rahmen seines Studiums und seiner Facharztweiterbildung nicht im Organisationsmanagement ausgebildet, entsprechendes Fachwissen muss er sich in der Regel in Eigenregie aus Fachliteratur und Kursen aneignen. Trotzdem wird vom Arzt über die medizinische Versorgung hinaus zunehmend verlangt, dass es seinen Arbeitsabläufe auch unter wirtschaftlichen Gesichtspunkten optimiert. In dieser Arbeit werden verschiedene Methoden des Prozessmanagements für ihre Anwendung in der Radiologie erprobt. Unter Zuhilfenahme von einfachen papierbasierten Methoden lässt sich bereits ein Großteil von Arbeitsprozessanalysen durchführen. Bei komplexen Arbeitsabläufen wird man eine Methode wählen, die möglichst genaue qualitative und quantitative Aussagen über zu erwartende Effekte liefert. Vorgestellt werden diesbezüglich die Netzplantechnik und die Prozesssimulation anhand des computertomographischen und sonographischen Arbeitsplatzes.
description: Within a hospital, the radiologist considerably influences the patient s length of stay through the availability of service and diagnostic information. Therefore, coordination and timing radiologic examinations become increasingly more important. Physicians are not taught organizational management during their medical education and residency training, and the necessary expertise in economics is generally acquired through literature or specialized courses. Beyond the medical service, the physicians are increasingly required to optimise their work flow according to economic factors. This review introduces various tools for process management and its application in radiology. By means of simple paper-based methods, the work flow of most processes can be analysed. For more complex work flow, it is suggested to choose a method that allows for an exact qualitative and quantitative prediction of the effect of variations. This review introduces network planning technique and process simulation.

description: We consider a diffuse interface model for tumor growth consisting of a Cahn--Hilliard equation with source terms coupled to a reaction-diffusion equation, which models a tumor growing in the presence of a nutrient species and surrounded by healthy tissue. The well-posedness of the system equipped with Neumann boundary conditions was found to require regular potentials with quadratic growth. In this work, Dirichlet boundary conditions are considered, and we establish the well-posedness of the system for regular potentials with higher polynomial growth and also for singular potentials. New difficulties are encountered due to the higher polynomial growth, but for regular potentials, we retain the continuous dependence on initial and boundary data for the chemical potential and for the order parameter in strong norms as established in the previous work. Furthermore, we deduce the well-posedness of a variant of the model with quasi-static nutrient by rigorously passing to the limit where the ratio of the nutrient diffusion time-scale to the tumor doubling time-scale is small.

title: How interviewing techniques and temperament affect children as eyewitnesses and jurors' perceptions
Creators: name: Cotterill, Ben F.
Publisher: name: Edinburgh Napier University
Year: 2022

description: The aim of this research was to better understand how the temperament of a child witness may affect their eyewitness performance and the perception of mock-jurors during different interview conditions. In Study One, a new self-report method (the Temperament Assessment Tool for Children; TATC) was developed for assessing temperament traits in 4- to 8-year-old children. Internal consistency and test-retest reliability was found to be satisfactory overall with 202 participants. In Study Two, the same 4- to 8-year-old children watched a video of a theft and were interviewed using open, closed, or misleading questions about what they remembered. The children also completed the TATC. Witnesses in the open-ended condition were significantly more accurate overall than those in the other interview conditions. Temperament characteristics that limit attention (i.e., distractibility) predicted an overall higher number of errors during the interview, while misleading questions were particularly detrimental to the accuracy of less adaptable and less persistent children. In Study Three, a sample of 82 mock-jurors read transcripts of interviews with child witnesses (6 to 8 years old) from the previous study. Mock-jurors were randomly assigned to one of three interview conditions (open-ended, closed-ended, or misleading). The child witnesses varied in levels of shyness (i.e., high, moderate, and low) according to self-reports, gathered in the previous study. Contrary to the researcher's hypothesis, the findings indicated that interview condition had no impact on the mock-jurors’ perceived reliability of witnesses. Furthermore, the shyness of the child witness overall did not affect the perception of mock-jurors. Mock-juror perceptions were, however, influenced by their own personality traits. For example, those higher in withdrawal, an aspect of neuroticism, were more likely to rate child witnesses favourably. Overall, the results of this research provide some support for the assertion that certain temperament traits can impact the eyewitness performance of child witnesses and that closed-ended and misleading questions are unwise due to an overall decrease in accuracy.

This thesis therefore investigated epidemiology, aetiology and a potential preventative measure of concussion in professional rugby union in Scotland by following van Mechelen’s “Sequence of Prevention of Sports Injuries” model (van Mechelen et al, 1992) and other injury investigation methodologies (Fuller & Drawer, 2004; Meeuwisse et al, 2007). Following research recommendations from the rugby research consensus (Fuller et al, 2007d), medically collected injury data and GPS match and training exposure demonstrated concussion was the primary match injury in four of the five professional cohorts in Scotland during the 2017/18 and 2018/19 seasons. Concussion incidences were 22.5-37.3/1000 player match hours. Regression analysis of intrinsic concussion history and extrinsic contact event specific risk factors for concussion outcome found severity of most-recent concussion, high impact forces and being struck on the head and shoulder to statistically increase probability of concussion in tackle situations. The results imply that rule changes to the game of rugby and implementation of individualised concussion recovery protocols may reduce probability of concussion outcomes. A novel neck training programme to improve neck function and reduce concussion incidence was found to result in statistical improvements in neck strength and endurance for the intervention group compared with the control. Match concussion incidences were 7.7 (intervention) and 18.4/1000 player match hours (control). As a result, further work to implement this programme on a wider scale throughout Scottish Rugby was recommended. Concussion can cause various short- and long-term implications for individual players and professional rugby union squads. This thesis suggests possible future areas of research that are hoped to be developed to attempt to reduce concussion incidence in both Scottish and world-wide professional rugby union.

description: The methods for studying the epoch of cosmic reionization vary from full radiative transfer simulations to purely analytical models. While numerical approaches are computationally expensive and are not suitable for generating many mock catalogs, analytical methods are based on assumptions and approximations. We explore the interconnection between both methods. First, we ask how the analytical framework of excursion set formalism can be used for statistical analysis of numerical simulations and visual representation of the morphology of ionization fronts. Second, we explore the methods of training the analytical model on a given numerical simulation. We present a new code which emerged from this study. Its main application is to match the analytical model with a numerical simulation. Then, it allows one to generate mock reionization catalogs with volumes exceeding the original simulation quickly and computationally inexpensively, meanwhile reproducing large scale statistical properties. These mock catalogs are particularly useful for CMB polarization and 21cm experiments, where large volumes are required to simulate the observed signal.

description: Multijunction thin film modules are of ever greater interest, due to their high efficiency values
recorded in the literature. Spectral response measurements on such devices require a careful usage of coloured bias
light and also present additional difficulties when applied to large area modules: the method should avoid current
limitation by the junction producing less current at a given wavelength, due to series connection of junctions in the
device. In this work we present details of the method recently developed at ESTI for spectral response measurements
of large area thin film multijunction modules. The mismatch factor calculation for the same devices is also shown:
this is done by the convolution of the measured spectral response of each junction and of the reference cell with the
spectrum of our Large Area Pulsed Solar Simulator and with the standard AM1.5 spectrum.
MOON: A Mixed Objective Optimization Network for the Recognition of Facial Attributes

description: Attribute recognition, particularly facial, extracts many labels for each image. While some multi-task vision problems can be decomposed into separate tasks and stages, e.g., training independent models for each task, for a growing set of problems joint optimization across all tasks has been shown to improve performance. We show that for deep convolutional neural network (DCNN) facial attribute extraction, multi-task optimization is better. Unfortunately, it can be difficult to apply joint optimization to DCNNs when training data is imbalanced, and re-balancing multi-label data directly is structurally infeasible, since adding/removing data to balance one label will change the sampling of the other labels. This paper addresses the multi-label imbalance problem by introducing a novel mixed objective optimization network (MOON) with a loss function that mixes multiple task objectives with domain adaptive re-weighting of propagated loss. Experiments demonstrate that not only does MOON advance the state of the art in facial attribute recognition, but it also outperforms independently trained DCNNs using the same data. When using facial attributes for the LFW face recognition task, we show that our balanced (domain adapted) network outperforms the unbalanced trained network.

title: A study of entrepreneurial action within the social enterprise sector of Scotland
Creators: name: Anderson, Margaret Ann
Publisher: name: Edinburgh Napier University

description: Social enterprises exist to deliver a specific social or environmental mission. In Scotland they operate in a diverse range of sectors including housing, health and community development. It is both their diversity and contribution that provided the impetus for this study.

Entrepreneurship as an academic subject area is prevalent and spans many areas including business, universities, and society. However, the role of entrepreneurship in the social enterprise sector is not well understood. There is little discussion or discourse specifically of the “enterprise” element of social enterprises. This study sought to address this gap by mapping current entrepreneurial approaches, attitudes, activities, and support within the social enterprise sector. It set out to consider how the role of entrepreneurship in the social enterprise sector and how it can be supported to develop the entrepreneurial potential of social enterprises.

The study was undertaken from an interpretivist stance with semi-structured interviews with participants from across the social enterprise sector. The analysis wasthematic and brought to light different levels and perceptions of understanding of entrepreneurial action within social enterprises. It also evidenced a wide range of entrepreneurial activities and approaches currently being undertaken in the sector, often confined to specific organisations, but with potential to be shared and disseminated across the sector. Entrepreneurial approaches focused on providing pathways to increased economic sustainability and embedding entrepreneurship in the organisation.

The key contribution of the study is a qualitative review of the entrepreneurial orientation model, developing a framework with which organisations in the social enterprise sector can gain an understanding of their entrepreneurial stance. A set of recommendations focusses on ideas to develop the entrepreneurial potential of the sector, building on existing initiatives, and offering collaboration and support.
title: Studies on PDE4 cyclic AMP-specific phosphodiesterases
Creators: name: O'Connell, Jonathan Curtis

Subjects: subject: Molecular biology.

description: The type 4 family of phosphodiesterases (PDEs) are part of family of enzymes that provide the sole means of hydrolysing the ubiquitous second messenger, adenosine-3',5'-cyclic monophosphate. The PDE4 family is complex, consisting of four genes, each of which is alternatively spliced. Understanding the functional significance of the multiple species is crucial so as to enable the development of novel drugs to modulate their activities for the treatment of many disorders, including depression, asthma and arthritis. In this study, the regulation of PDE4B splice variants by insulin in intact rat epididymal adipocytes was investigated and the expression of PDE4B species in a number of cell lines was detected using antisera designed to recognise the C-terminal region of PDE4B species. Described herein is the first demonstration of the interaction of PDE4 isoforms with Src homology-3 (SH3) domains. The PDE4A species, rpde6 (RNPDE4A5) and the PDE4D species PDE4D4, when expressed either transiently in COS cells or endogenously in brain, were shown to possess the ability to bind to SH3 domains of certain Src family tyrosyl kinases, that were expressed as glutathione-S-transferase (GST) fusion proteins. Neither PDE isoforms interacted with GST itself PDE4D4 and rpde6 displayed little or no binding to the SH3 domains of the adapter proteins Grb2 and Crk, thus displaying specificity for the SH3 domains with which they interacted. Interaction was determined by the N-terminal splice region of rpde6 since the PDE4A splice variant rpde39, which differs from rpde6 at the N-terminus failed to interact with SH3 domains at all. This occurred both when rpde39 was either transiently expressed in COS cells or endogenously expressed in testes. The interaction of PDE4D4 with SH3 domains appeared to be determined by its N-terminal splice region since the other PDE4D splice variants, PDE4D3 and PDE4D5, which differ from PDE4D4 only in their extreme N-terminally spliced regions, did not interact with SH3 domains rpde6 but not PDE4D4 was shown to interact with the SH3 domains of Crk, Lck and Csk, as well as the cytoskeletal protein fodrin, leading to a perturbation of the catalytic activity of rpde6. In contrast, association with the SH3 domains of Src family tyrosyl kinases, Src, Fyn and Lyn did not effect the catalytic activity, Km or sensitivity to the PDE4 specific inhibitor rolipram of rpde6. The basis and possible functional significance of such interactions is described.

description: Plasma enhanced chemical vapor deposition of microcrystalline silicon growing at low temperature
recently attracts great attention in the field of solar energy sector, especially for the manufacturing of thin film solar
cells. A preliminary study on microcrystalline silicon thin film formation through a mixture of SiH4 and H2 gases with
the help of Ar plasma enhancement is conducted in this work. Plasma models are employed to investigate the
chemical reaction of gases and plasma inside plasma chambers. The kinetics of gas-phase species in the chamber is
considered for understanding the influences of working parameters on the production and consumption of different
species, where 17 species and 37 chemical reactions among electron, ions, radicals and neutral species are taken into
account. The proposed two-dimensional simulation can deliver important information of the key species near the
substrate for growing thin film on the substrate and also elucidate the major mechanisms, which dominate the
deposition process on the substrate.

description: Consider the following stochastic partial differential equation, \begin{equation*} \partial_t u_t(x)= \mathcal{L}u_t(x)+ ξσ(u_t(x)) \dot F(t,x), \end{equation*} where $ξ$ is a positive parameter and $σ$ is a globally Lipschitz continuous function. The stochastic forcing term $\dot F(t,x)$ is white in time but possibly colored in space. The operator $\mathcal{L}$ is a non-local operator. We study the behaviour of the solution with respect to the parameter $ξ$, extending the results in \cite{FoonNual} and \cite{Bin}
