description: Background: Ras homologous (Rho) family GTPases play a pivotal role in the regulation of numerous cellular functions associated with malignant transformation and metastasis. To evaluate the role of these GTPases in colorectal cancer, the mRNA expression levels in matched sets of tumor and non-tumor tissues from surgical specimens were analyzed. The relationship between the mRNA levels in tumor tissues to the clinicopathological features was also assessed. Methods: A total of 68 patients with colorectal carcinoma were recruited and the levels of RhoA and RhoC mRNA transcripts in cancer, paratumoral and normal tissues were characterized by quantitative real-time polymerase chain reaction (QRT-PCR). Their correlation to clinical histopathological parameters was analyzed. Results: The levels of RhoA and RhoC mRNA transcripts in carcinoma tissues were significantly higher than those in the matched paratumor and normal tissues from the same patient (p<0.05). The expression levels of both genes were significantly correlated with metastasis of cancer cells to lymph nodes and liver (p<0.05). The levels of RhoA expression were significantly correlated with the histopathological degree of cancer, while the expression of RhoC was correlated with the extent of local invasion to intestine. Conclusions: This is the first study with QRT-PCR to examine the expressions of RhoA and RhoC genes in colorectal carcinoma of Chinese patients. The significantly up-regulated RhoA and RhoC expressions suggest that they may contribute to the initiation, development, invasion and metastasis of colorectal carcinoma in Chinese patients.

description: Fuel-parity, i.e. the intersection of fossil fuel prices with PV generation cost, represents a major milestone for further
photovoltaic (PV) diffusion besides grid-parity. A fuel-parity model is presented, which is based on levelized cost of
electricity (LCOE) coupled with the experience curve approach. Preconditions for a successful hybridization of PV
and fossil fuel power plants are discussed. The global fossil fuel power plant capacity is analysed for the economic
hybridization market potential on a georeferenced localized basis for all fossil fuel power plants. LCOE of fossil fuel
power plants are converging with those of PV in sunny regions, but in contrast to PV are mainly driven by fuel cost.
As a consequence of cost trends this analysis estimates an enormous worldwide market potential for PV power plants
by the end of this decade in the order of at least 900 GWp installed capacity without any electricity grid constraints
leading to a fast diffusion of hybrid PV-Fossil power plants. The complementary power feed-in of PV and wind
power plants might result in hybrid PV-Wind-Fossil power plants in regions of good solar and wind resources. In the
mid- to long-term the remaining fossil fuels might be substituted by renewable power methane by using the existing
downstream natural gas infrastructure. In conclusion, PV is on the pathway to become a highly competitive energy
technology.

description: We study the fate of algebraic decay of correlations in a harmonically trapped two-dimensional degenerate Bose gas. The analysis is inspired by recent experiments on ultracold atoms where power-law correlations have been observed despite the presence of the external potential. We generalize the spin wave description of phase fluctuations to the trapped case and obtain an analytical expression for the one-body density matrix within this approximation. We show that algebraic decay of the central correlation function persists to lengths of about 20% of the Thomas--Fermi radius. We establish that the trap-averaged correlation function decays algebraically with a strictly larger exponent weakly changing with trap size and find indications that the recently observed enhanced scaling exponents receive significant contributions from the normal component of the gas. We discuss radial and angular correlations and propose a local correlation approximation which captures the correlations very well. Our analysis goes beyond the usual local density approximation and the developed summation techniques constitute a powerful tool to investigate correlations in inhomogeneous systems.

title: From algorithm selection to generation using deep learning
Creators: name: Alissa, Mohamad
Publisher: name: Edinburgh Napier University
Year: 2022

description: Algorithm selection and generation techniques are two methods that can be used to exploit the performance complementarity of different algorithms when applied to large diverse sets of combinatorial problem instances. As there is no single algorithm that dominates all others on all problem instances, algorithm selection automatically selects an algorithm expected to perform best for each problem instance. Meanwhile, algorithm generation refers to combining different algorithms in a manner that allows the resulting method to improve the efficacy of a pool of algorithms.

This thesis examines algorithm selection and generation within a single streaming problem domain, that is Bin-Packing, where novel approaches are proposed and evaluated on large problem sets. This research starts with presenting a novel feature-free approach to select the best performing heuristic by capturing the sequential information implicit in a streaming instance and using this as direct input to two Deep Learning (DL) models, Long-Short-Term Memory (LSTM) or Gated Recurrent Unit (GRU), to learn a mapping from an instance to an algorithm. Results obtained using the proposed approach show that the performance of the feature-free selectors significantly outperforms the performance of both the single best solver and the classical feature-based approach using well-known Machine Learning (ML) classifiers when applied to large sets of diverse problem instances. Next, a more radical approach is proposed: bypass algorithm selection altogether by training encoder-decoder LSTM using solutions obtained from a set of algorithms to directly predict a solution from the instance data behaving as an automatically generated algorithm. Experiments conducted on large datasets using problem batches of varying sizes show that the generated algorithm is able to accurately predict solutions, particularly with small batch sizes. Finally, the thesis develops the proposed encoder-decoder approach by introducing a novel neural approach for generating algorithms, in which a neural network acts as an algorithm by generating decisions. Two architectures are evaluated, an encoder-decoder LSTM and a feed-forward Neural Network (NN), and trained using the decisions output from existing algorithms on a large set of instances. Experiments show that the new generated algorithms are capable of solving a subset of instances better than the well-known bin-packing algorithms, and hence they can significantly improve the overall performance when they are added to a pool of algorithms.
Dynamo model for grand maxima of solar activity: can superflares occur on the Sun?

description: Recent data on superflares on sun-like stars and radiocarbon data on solar activity in the past are both indicative of transient epochs of unusually high magnetic activity. We propose an explanation for the grand activity maxima in the framework of a solar dynamo model with fluctuating parameters. Solar-type dynamos are oscillatory because of the combination of the solar-type differential rotation with positive (in the Northern hemisphere) alpha-effect. An artificial reversal of the sign in the alpha-effect changes the dynamo to a steady regime with hundreds of times larger magnetic energy compared to the amplitude of the cyclic dynamo. Sufficiently large and durable fluctuations reversing the sign of the alpha-effect during the growth phase of a magnetic cycle can, therefore, cause a transient change to a steady dynamo with considerably increased magnetic energy. This qualitative scenario for grand activity maxima is supported by computations of the dynamo model with a fluctuating alpha-effect. The computed statistics of several thousand magnetic cycles gives examples of cycles with very high magnetic energy. Our preliminary estimations, however, suggest that the probability of solar superflares is extremely low.

description: The successful implementation of “Feed in Tariff” in Germany and many other countries lead to a
growing market and declining system price. As a result of this the number of small PV systems, with less than 10
kWp, in private households increased rapidly. More than 98 % of these systems are connected to the low voltage grid
and cover about 20 % of the electricity demand of a city on Sundays. This situation starts to have an effect on the
stability of the low voltage grid in different grid areas: city, suburban and countryside. Violations of the voltage
tolerance (norm VDE) and effects to the life time of transformers are possible. The main questions in this situation
are the following: how can the distribution system operator observe and protect the stability of the grid and how this
information can be used for the management of the accounting grid.

description: Justification for Scoping Review: Systematic, critical literature and scoping reviews are various ways of collecting, analyzing and presenting available evidence about a specific topic. Each review type has its strengths and limitations. The systematic review methodology provides a framework and the tools and methods requisite for analysing and synthesizing the most relevant empirical evidence on a topic., It is a rigorous approach to collecting and selecting the best available empirical data so that it can be used to inform policy, program or clinical decisions, while providing guidance for the trajectory of future and/or new research., Critical literature reviews are narrative accounts of information that is currently available, accessible, and published, which may be written from a number of differing paradigms or perspectives depending on the author’s standpoint. They provide an awareness of the current state of knowledge in a subject area, and synthesize evidence to reveal limitations, strengths, omissions, and biases. Unlike systematic reviews, critical literature reviews are not bound by either rigorous, rule-driven search processes or quality assessments, or transparent criteria for data abstraction or reporting on all relevant literature. Uniquely, scoping reviews aim to coalesce and analyse a broad range of both published and unpublished research and non-research, to provide conceptual clarity and understanding of a particular topic or evidence base. Since 2017, a mix of peer reviewed literature, anecdotal evidence, and organizational reports have emerged on the myriad of impacts of Trump’s expansion of the GGR. The most appropriate review methodology for synthesizing all published impacts on the current iteration of the policy is a scoping review methodology. In 2019, Mavodza et al. published the results of a scoping review documenting the published impacts of the GGR on SRHR from 1984 to October 2017. This proposed scoping review will use Mavodza et al. as a foundation, building upon the methodology as appropriate. To the authors’ knowledge, this will be the first scoping review that examines the impact of the GGR on global health from 2017-2020.

description: Godunov Smoothed Particle Hydrodynamics (Godunov SPH) method is a computational fluid dynamics method that utilizes a Riemann solver and achieves the second-order accuracy in space. In this paper, we extend the Godunov SPH method to elastic dynamics by incorporating deviatoric stress tensor that represents the stress for shear deformation or anisotropic compression. Analogously to the formulation of the original Godunov SPH method, we formulate the equation of motion, the equation of energy, and the time evolution equation of deviatoric stress tensor so that the resulting discretized system achieves the second-order accuracy in space. The standard SPH method tends to suffer from the tensile instability that results in unphysical clustering of particles especially in tension-dominated region. We find that the tensile instability can be suppressed by selecting appropriate interpolation for density distribution in the equation of motion for the Godunov SPH method even in the case of elastic dynamics. Several test calculations for elastic dynamics are performed, and the accuracy and versatility of the present method are shown.

description: Anomalous chiral conductivities in theories with global anomalies are independent of whether they are computed in a weakly coupled quantum (or thermal) field theory, hydrodynamics, or at infinite coupling from holography. While the presence of dynamical gauge fields and mixed, gauge-global anomalies can destroy this universality, in their absence, the non-renormalisation of anomalous Ward identities is expected to be obeyed at all intermediate coupling strengths. In holography, bulk theories with higher-derivative corrections incorporate coupling constant corrections to the boundary theory observables in an expansion around infinite coupling. In this work, we investigate the coupling constant dependence and universality of anomalous conductivities (and thus of the anomalous Ward identities) in general, four-dimensional systems that possess asymptotically anti-de Sitter holographic duals with a non-extremal black brane in five dimensions, and anomalous transport introduced into the boundary theory via the bulk Chern-Simons action. We show that in bulk theories with arbitrary gauge- and diffeomorphism-invariant higher-derivative actions, anomalous conductivities, which can incorporate an infinite series of (inverse) coupling constant corrections, remain universal. Owing to the existence of the membrane paradigm, the proof reduces to a construction of bulk effective theories at the horizon and the boundary. It only requires us to impose the condition of horizon regularity and correct boundary conditions on the fields. We also discuss ways to violate the universality by violating conditions for the validity of the membrane paradigm, in particular, by adding mass to the vector fields (a case with a mixed, gauge-global anomaly) and in bulk geometries with a naked singularity.

description: Background: The technology to recognize nucleated red blood cells (NRBC) automatically has only recently been developed. Modern hematology analyzers allow for rapid and accurate NRBC counts. The goal of our study was to evaluate NRBC counts and the concentrations of serum transferrin receptor (sTfR) in patients affected by different thalassemia syndromes and hereditary spherocytosis. We wished to gain a better understanding of the meaning of the presence of NRBC in peripheral blood and the relationship of the two parameters with effective and ineffective erythropoiesis in the different thalassemia syndromes. Methods: NRBC counts in peripheral blood were evaluated in a large group of patients with thalassemia (36 thalassemia major, 55 thalassemia intermedia and 61 Sβ-thalassemia patients) and compared with data from 29 patients with hereditary spherocytosis; in all the patients the concentration of sTfR was evaluated as an index of global erythropoiesis. Results: The NRBC count showed a good relationship with ineffective erythropoiesis: highest counts were observed in the thalassemia syndromes characterized by almost completely ineffective erythropoiesis. NRBCs were absent in patients affected by hereditary spherocitosis, a disease characterized by effective erythropoiesis. Conclusions: The NRBC count can be useful for better defining ineffective erythropoiesis in patients with thalassemia, and can help optimize transfusion therapy in severe thalassemia syndromes.

description: As a meaning for efficiency improvement of conversion of solar radiation to other types of energy,
solar tracking systems are used. The paper presents an analysis of loads and also FEM stress and displacement
analysis of an experimental solar tracking system. The tracking system is azimuthal, with two rotational axis: a
vertical fixed axis and a horizontal mobile axis. The system is one of ten different tracking systems for PV individual
panels implemented, this year, in the campus of the Transilvania University of Braov, Romania. It has been
developed in order to research the optimization of the mechanical system of trackers as a meaning of improving the
costs and energy efficiency of the system. There have been considered the loading cases depending on the functional
positions of the tracking system (positions corresponding to minimum and maximum rotational angles), considering
different wind loads, according to Eurocode. Final conclusions have been drawn on the most appropriate loading
cases that must be considered in preliminary design and also in further development of Eurocode.

description: The role of oxygen in close space sublimation (CSS) deposited CdS films upon the performance of CdTe/CdS solar cells
was investigated. CdS films were deposited using a range of oxygen pressures, with the effect on device performance
being assessed by J-V, external quantum efficiency and optical beam induced current (OBIC) analysis. By inclusion of
increased quantities of oxygen into the CdS deposition ambient (0 - 4 Torr) the average device VOC was found to increase
from 0.57 V to 0.67 V, whilst all other parameters showed no systematic variation. Multi-wavelength OBIC analysis of
devices with CdS layers deposited under vacuum and oxygen (but otherwise similar), revealed those with oxygen to have
a more uniform photovoltaic response. High resolution SEM analysis of CdS layers shows the range of CdS grain size
achievable by CSS deposition. Further improvements to all-CSS deposited cells are reported with cell efficiencies of up
to 11.65% being measured.
Topological insulator on honeycomb lattices and ribbons without inversion symmetry

description: We study the Kane-Mele-Hubbard model with an additional inversion-symmetry-breaking term. Using the topological Hamiltonian approach, we calculate the $\mathbb{Z}_2$ invariant of the system as function of spin-orbit coupling, Hubbard interaction $U$, and inversion-symmetry-breaking on-site potential. The phase diagram calculated in that way shows that, on the one hand, a large term of the latter kind destroys the topological non-trivial state. On the other hand, however, this inversion-symmetry-breaking field can enhance the topological state, since for moderate values the transition from the non-trivial topological to the trivial Mott insulator is pushed to larger values of interaction $U$. This feature of an enhanced topological state is also found on honeycomb ribbons. With inversion symmetry, the edge of the zigzag ribbon is magnetic for any value of $U$. This magnetic moment destroys the gapless edge mode. Lifting inversion symmetry allows for a finite region in interaction strength $U$ below which gapless edge modes exist.

description: The level of PV installations is rapidly approaching >35GW worldwide. Conventional wisdom is that
the need for renewables will continue the drive to increased PV implementation. However, there are several key points
of concern which are now developing which may limit the expansion of PV and need to be addressed. The following
issues may begin to limit the sustained PV growth: (1) as PV and renewables reach a significant level of energy
generation, at what point will the Utilities not be accepting the inputs for various reasons, (2) if the grid is not accepting
the PV power input then what is the impact on the FIT models of revenue generation, (3) at what level is the
“dispatchability” requirement a major factor in determination of the PV choice, (4) what are the best strategies for
storage and what are the current developments particularly for CSP (Concentrated Solar Power ), as well as more
standard approaches more suitable to PV.
This paper examines key developing trends across the globe where the issues of PV supply may be impacted by larger
considerations such as the grid availability. The ultimate goal of baseline energy from PV requires addressing
intermittency, dispatchability and storage. A survey of storage is provided with a focus on CSP options. The relative
cost considerations of the different solar approaches are examined. The aspect of grid “readiness” for acceptance is
also examined with case studies. Market research analysis is developed looking at the specifics of dispatchability,
regional grid issues, and storage. Quantitative comparisons for different solar approaches and wind are presented.
Learning from the wind sector is highlighted as it is ~10x that of PV. Specific strategies are developed and discussed
in the context of preparation for acceleration of solar as a power source.
title: Exercise protection of vascular endothelial cells against breast cancer chemotherapy toxicity: Evidence from in vitro serological studies
Creators: name: Mclaughlin, Marie
Publisher: name: Edinburgh Napier University
Year: 2022

description: 5-fluorouracil, epirubicin, cyclophosphamide, and docetaxel is an effective chemotherapy regimen for early-stage breast cancer (BC). However, these drugs associate with a 5% incidence of heart failure (HF). To attenuate the cardiovascular toxicity of chemotherapy, exercise has been proposed as a potential preventative measure. There is now emerging evidence for protective effects of exercise on the heart but there is a lack of evidence for vascular effects, despite vascular endothelial dysfunction being an initiating step in cardiovascular disease (CVD) development.

This study aimed to determine if there are protective effects of habitual physical activity, a single acute exercise session, and an exercise training intervention on chemotherapyinduced vascular endothelial cell toxicity. It was hypothesised that serological factors in active women can alleviate vascular toxicity from chemotherapy; and an acute exercise session and an exercise training intervention can alleviate toxicity in previously sedentary women.

To investigate protective effects of exercise, a novel ex vivo method was used. Endothelial cell cultures were preconditioned with serum from active and sedentary woman; woman pre- and post-acute exercise bout; and woman pre- and post-exercise intervention. After 24-hours of serum preconditioning, endothelial cells were exposed to physiological concentrations of 5-fluorouracil, epirubicin, cyclophosphamide, and docetaxel. Cell viability and function, and wound repair were assessed using flow cytometry and scratch assays (to simulate a wound), respectively.

Overall, results confirm that FEC-T chemotherapy drugs, commonly used in early-stage BC treatment, elicit significant damage and dysfunction of endothelial cells. Exercise serum preconditioning from active women, serum collected after an acute exercise session, and serum collected after an exercise training intervention, elicited some protection of endothelial cells against the usual toxicity of 5-fluorouracil, epirubicin, cyclophosphamide, and docetaxel, when compared to control serum preconditioning from inactive women, serum collected prior to an acute exercise session, and serum collected prior to an exercise training intervention, respectively.

description: Using the Sen's entropy function formalism, we compute the entropy for the extremal dyonic black hole solutions of theories in the presence of dilaton field coupled to the field strength and a dilaton potential. We solve the attractor equations analytically and determine the near horizon metric, the value of the scalar fields and the electric field on the horizon, and consequently the entropy of these black holes. The attractor mechanism plays a very important role for these systems, and after studying the simplest systems involving dilaton fields, we propose a general ansatz for the value of the scalar field on the horizon, which allows us to solve the attractor equations for gauged supergravity theories in $AdS_4$ spaces. In particular, we derive an expression for the dyonic black hole entropy for the $\mathcal{N}=8$ gauged supergravity in 4 dimensions which does not contain explicitly the gauge parameter of the potential.

description: Using non-equilibrium Green's functions, we studied numerically the transport properties of a Josephson junction, superconductor-topological insulator-superconductor hybrid system. Our numerical calculation shows first that proximity-induced superconductivity is indeed observed in the edge states of a topological insulator adjoining two superconducting leads and second that the special characteristics of topological insulators endow the edge states with an enhanced proximity effect with a superconductor but do not forbid the bulk states to do the same. In a size-dependent analysis of the local current, it was found that a few residual bulk states can lead to measurable resistance, whereas because these bulk states spread over the whole sample, their contribution to the interference pattern is insignificant when the sample size is in the micrometer range. Based on these numerical results, it is concluded that the apparent disappearance of residual bulk states in the superconducting interference process as described in Ref. [\onlinecite{HartNautrePhys2014f}] is just due to the effects of size: the contribution of the topological edge states outweighs that of the residual bulk states.

description: The group $Σ(36\times3)$ with the generalized CP transformation is introduced to predict the mixing pattern of leptons. Various combinations of abelian residual flavor symmetries with CP transformations are surveyed. Six mixing patterns could accommodate the fit data of neutrinos oscillation at $3σ$ level. Among them, two patterns predict the nontrivial Dirac CP phase, around $\pm 57^{\circ}$ or $\pm 123^{\circ}$, which is in accordance with the result of the literature and the recent fit data. Furthermore, one pattern could satisfy the experimental constraints at $1σ$ level.

power measurements. Two so-called component reference cells serve as detectors during the setting of the solar
simulator and represent individually the two sub-cells in the a-Si/μ-Si tandem structure. The inserted filters in the
component reference cells were optimized for optical transmissions to achieve the best match to the devices tested.
In parallel the different generations of reference cells and the measurement techniques are presented. Several
development steps finally resulted in a set of component reference cells having the WPVS design and were calibrated
as primary standards. The main characteristics of these references are discussed. Furthermore, the spectral mismatch,
spectral match of the component cells to the sub-cells of the Micromorph tandem cell are calculated and the method
of setting the simulator is reviewed.
title: The influence of perceived levels of physical activity on engagement with cardiac rehabilitation after acute coronary syndrome

description: Background: Cardiac rehabilitation (CR) is an effective therapy to reduce the risk of hospital readmission after an acute coronary syndrome (ACS) diagnosis. Despite this, half of eligible individuals do not engage. The reasons for this are complex and include patient-level barriers such as beliefs about being already active. Indeed, up to 40% of eligible individuals report meeting physical activity (PA) guidelines prior to attendance, yet little is known about how this influences CR engagement decisions. Therefore, the aim of this thesis was to provide evidence about how previous experience of PA influenced PA and CR engagement after an ACS diagnosis.

Methods: Firstly, a systematic review of 12 studies, representing 388 participants from six countries, explored how previous PA experience influenced engagement with PA during CR was undertaken. Subsequently, a mixed methods explanatory sequential study included a cross-sectional element examining self-reported PA levels, illness perceptions and physical self-descriptions for 67 participants (mean age 64.2 (±10.53SD)), and a qualitative element involving telephone interviews with 26 previously active ACS survivors (aged 44-77 years).

Results: Systematic review synthesis indicated that perceptions of physical ability, exercise self-reliance, severity of cardiac condition and fitness identity influenced perceived CR need. In the mixed-methods study, perceptions of previous PA levels influenced PA engagement decisions after an ACS diagnosis and during CR. Most participants (n=50, 74.6%) self-reported being at least moderately active and self-concept for being active predicted self-reported PA prior to CR. Participants understood ‘being active’ through the lens of previous PA and self-evaluation of health. CR communication and peer comparisons influenced engagement decisions and motivation for fitness goals. Individuals who self-reported being at least moderately active required CR support to increase PA intensity levels after an ACS diagnosis.

Conclusions: ACS survivors conceptualise “being active” based on previous PA experience and these preconceptions influence future fitness goals.
title: Perspectives on leading change: Exploring change readiness strategies used in the Bahamian financial services sector

description: The Bahamian financial services sector is experiencing tremendous change driven largely by regulatory initiatives and technological innovation. The purpose of this thesis is to explore the perspectives of senior executives in this context on organisational readiness for change and its perceived impact.

A social constructionist ontology and interpretivist epistemology were employed to identify consistent themes and analyse findings. Data was collected using twenty semi-structured interviews of senior executives. The study revealed key themes of communication, capacity building, leadership, cross-functional collaboration and stakeholder engagement, a flexible approach to policy procedure and practice and organisational culture to elucidate the barriers and precursors to successful transformation. The findings indicated that senior executives understand the construct of change readiness. Most participants perceived there to be a high level of readiness within their respective institutions. While it was expected that there would be a greater appreciation for the active role played by senior executives in creating readiness, this was not the case. The majority of participants intimated that creating readiness was a task for external consultants and change agents other than themselves. It became clear, considering strategic leadership and relational awareness theory, that there was an opportunity to provide a mechanism that would highlight the vital role of senior executives in creating change readiness. In addition, an inconsistent approach was used by international and indigenous financial institutions to create readiness. Hence, the provision of a “strategic readiness awareness” tool is proposed that may be used across all types of financial institutions, increasing consistency across the sector to guide leaders on the considerations required to create organisational readiness for change.

Capacity building was identified as a precursor to change readiness by the majority of participants. While senior executives emphasised training and development, it was anticipated that a comprehensive knowledge management strategy would have been proffered as an enabler to change readiness. This was not the case, highlighting the need for a comprehensive knowledge management model. In addition, the misalignment of cultures between global head offices and Bahamas based subsidiaries or branches which could impact readiness was also revealed. Hence, there is an opportunity to adopt strategies to ensure that a consistent culture is embedded across the enterprise.

Based on the research findings, contributions are made to knowledge and practice. This thesis is based in the private regulated sector. Specific recommendations are put forward for use by a diverse range of financial institutions with specific recommendations also made for indigenous and international financial institutions.

description: The effects of spectral variations due to seasonal changes directly affect the device performance
parameters although for wider band gap devices such as Copper Indium Diselenide (CIS) modules the effect is often
neglected. We present the results of CIS module current-voltage (I-V) curves during winter and summer periods.
The outdoor spectral effects using the Weighted Useful Fraction (WUF) concept of CIS module is presented. The
results indicates that a change in season (summer/winter) result in the outdoor spectrum to vary which in turn result
in the decrease in the device short-circuit current (Isc).

description: The objective of IEA PVPS Task8 is to examine and evaluate the potential of Very Large Scale
Photovoltaic Power Generation (VLS-PV) Systems on desert areas, which have a capacity ranging from multi-
Megawatt to Gigawatt, and to develop practical project proposals for implementing the VLS-PV systems in desert
regions. The Task8 was established in 1999, and has started the phase-4 activity (2009-2011). To implement real
VLS-PV projects, the main challenge is to make excellent project proposals and to convince local governments,
energy companies and financing institutions to be positively involved in the projects. Based on lessons learnt from
our previous studies and recent trends in the world, Task8 would publish the 4th edition of ‘Energy from the Desert’.
Clifford theory for glider representations

description: Classical Clifford theory studies the decomposition of simple $G$-modules into simple $H$-modules for some normal subgroup $H \triangleleft G$. In this paper we deal with chains of normal subgroups $1 \triangleleft G_1 \triangleleft \cdots \triangleleft G_d =G$, which allow to consider fragments and in particular glider representations. These are given by a descending chain of vector spaces over some field $K$ and relate different representations of the groups appearing in the chain. Picking some normal subgroup $H \triangleleft G$ one obtains a normal subchain and one can construct an induced fragment structure. Moreover, a notion of irreducibility of fragments is introduced, which completes the list of ingredients to perform a Clifford theory.

title: Assessment of trophic polymorphism in the Himalayan fish Tor putitora
Creators: name: Martin, Ian

description: An investigation into intra-specific morphological variation in Tor putitora fish from the Mahakali River in western Nepal was carried out. Three main hypotheses were tested: i) two distinct variants, one with thin lips and a forward-facing mouth (Type A), another with thick lips, an extended protrusion known as a mental lobe and more ventrally oriented mouth (Type B), can be distinguished by meristic, allometric or landmark-based morphometric analyses; ii) differences in ecological conditions in spatially separated breeding streams, potentially linked to environmentally influenced morphological variation, can be observed; iii) differences in stable isotope ratios of carbon and nitrogen obtained from fish scales, and therefore evidence of dietary divergence, are evident between the two morphotypes.

Meristic and allometric analyses provided no evidence of distinguishing features between the morphotypes, however the landmark-based morphometric analysis produced very strong evidence that the two morphotypes clearly differ in shape and features of the head and mouthparts. Analysis of the physico-chemical conditions and aquatic invertebrate communities in the spatially separated breeding streams produced results which refuted the second hypothesis but suggested strongly that differences between seasons (snow-melt and post-monsoon) were statistically significant and suggested an alternative hypothesis that breeding events may be segregated temporally, rather than spatially. Stable isotope analysis uncovered statistically significant differences in nitrogen isotope ratios which supported the hypothesis that the two morphotypes display divergence in diet, very likely linked to the morphological variation in the head and mouthparts.

This examination provides evidence of trophic polymorphism in T. putitora and illuminates the path to further studies of this phenomenon which has been observed in several other species of the same genus across south and southeast Asia.
