description: We investigate the extended Higgs sectors, specially the charged Higgs sector in a supersymmetric $Y=0$ $SU(2)$ triplet and a Standard Model (SM) gauge singlet extension of SM. We show that in this model the allowed data for the Higgs boson interaction eigenstates tend to group into separate blocks for $SU(2)$ triplet, doublet and singlet. The triplet sector has two degenerate paired states, each pair composed of a mostly-triplet charged Higgs and of a mostly-triplet scalar or pseudoscalar state. The mostly-doublet sector involves a Standard Model like Higgs of 125 GeV and extra mass-degenerate states, composed of a charged, a scalar and a pseudoscalar. The CP-odd component of the singlet scalar, after supersymmetry breaking, takes the role of a pseudo-Nambu-Goldstone mode in the $Z_3$ symmetric case, while the CP-even one becomes decoupled. In a second part of our study we investigate the different decay processes allowed to a charged Higgs boson of this model. Specifically, we search for general signatures of the TNMSSM in order to distinguish among Higgs fields belonging to $SU(2)$ doublet, triplet and singlet representations at the LHC. We also propose few golden plated final state modes carrying the distinctive signatures of this model which could be investigated in collider searches. We also show how in the decoupling limit of the triplet ($|λ_T| \simeq 0$) affects the decays as well as the production channels at the LHC.

title: Design, synthesis and biological evaluation of novel targeted anthelmintic agents
Creators: name: Rehan, Aiman

description: Parasitic helminth infections of livestock are a threat to the health and production of livestock, crops and to human health. One third of the world’s animal population was affected in 2015 by helminth infestations causing severe morbidity. The shortfall of new drugs against nematode parasites and the resistance hazard represents an urgent need for the development of novel anti-parasitic drugs with effective delivery to the target site. It is hypothesised that the toxic efficacy and selectivity of anthelmintic drugs can be improved using prodrug forms that possess intracellular drug targeting moieties that can circumvent resistance mechanisms.
A series of novel targeted anthelmintic candidate drugs have been synthesized, based on a colchicine (Col) core; code-named: AM1 (Col-prolinol), AM3 (Col-4hydroxypiperidine), AM4 (Col-(R)-3-pyrrolidinol), AM5 (Col-Boc-aminopyrrolidine) and AM6 (Col-aminopyrrolidine), these compounds are broadly tubulin targeting aminocolchicine derivatives. Amino-colchicines were then conjugated with a lipophilic, cationic targeting moiety TPP (triphenylphosphonium) ion that has potential to bypass resistance and achieve selectivity by direct and fast accumulation in the matrix of mitochondria. Novel prodrugs AM2 (Col-prolinol-TPP), AM7 (Col-aminopyrrolidineTPP), AM8 (Col-4-hydroxypiperidine-TPP), AM9 (Col-(R)-3-pyrrolidinol-TPP) are ester-linked triphenylphosphonium butanoyl (TPP) conjugates of amino-colchicines AM1, AM6, AM3 and AM4 respectively that are designed to not only pass through cell membranes and localise in the mitochondria but also facilitate drug cellular uptake by avoiding p-glycoprotein-type mediated efflux mechanisms. All novel compounds have been characterised by high resolution mass spectrometry and 1H and 13C NMR spectroscopy. Preliminary biological evaluation of AM1 and AM2 was carried out by treatment of the C. elegans non-parasite model organism. Results demonstrated that AM2 (100µM) showed significant toxicity against C. elegans at an incubation time of 22h. Physicochemical properties of these novel agents has been described in terms of distribution coefficient log D values, that showed they are lipophilic in nature and should have the ability to cross lipid bilayers and mitochondrial membrane. Preliminary molecular docking studies also demonstrated binding affinity of AM6 (Colaminopyrrolidine) with tubulin. These novel prodrugs have the potential to be developed as effective anthelmintic agents in the treatment of parasitic helminth disease.

HOLOTYPE: AMNH 695918, adult male, collected on Tacuta (5 Tagula 5 Sudest) Island, 11.30S, 153.30E (PNG, 1984), Louisiade Archipelago, Milne Bay Province, Papua New Guinea, on 8 April 1898, by A.S. Meek (no. 1696). From the Rothschild Collection. COMMENTS: Rothschild and Hartert cited Meek’s unique field number of the holotype in the original description but did not mention other specimens. However, Hartert (1898a: 527), in his account of Meek’s 1898 collection from Tacuta, reported under Ptilotis notata that Meek sent a series of seven specimens. Only six of those specimens came to AMNH with the Rothschild Collection. The five paratypes in AMNH are: males, AMNH 695917 (Meek no. 1723), AMNH 695919 (1712); females, AMNH 695927– 695929 (1603, 1743, 1785).

description: In this paper it is demonstrated how photoluminescence imaging (PLI) can serve to qualitatively and
quantitatively characterize the properties of an epitaxial silicon layer. In the first part a set of microelectronic-grade
samples is characterized electrically by determining the epitaxial layer lifetime. In the second part a set of samples
for photovoltaic application is studied. In this case the focus is on the possibilities for a qualitative analysis of the
thickness inhomogeneity of the epitaxial layer.
New perturbative method for analytical solutions in single-field models of inflation

description: We propose a new parametrization of the background equations of motion corresponding to (canonical) single-field models of inflation, which allows a better understanding of the general properties of the solutions and of the corresponding predictions in the inflationary observables. Based on the tools of dynamical systems, the method suggests that inflation comes in two flavors: power-law and de Sitter. Power-law inflation seems to occur for a restricted type of potentials, whereas de Sitter inflation has a much broader applicability. We also show a general perturbative method, by means of series expansion, to solve the new equations of motion around the critical point of the de Sitter type, and how the method can be used for arbitrary models of de Sitter inflation. It is then argued that for the latter there are two general classes of inflationary solutions, given in terms of the behavior of the tensor-to-scalar ratio as a function of the number $N$ of $e$-folds before the end of inflation: $r \sim N^{-1}$ (Class I), or $r \sim N^{-2}$ (Class II). We give some examples of the two classes in terms of known scalar field potentials, and compare their general predictions with constraints obtained from observations.

title: The dynamics of police legitimacy and social media in Scotland
Creators: name: Ralph, Liam David
Publisher: name: Edinburgh Napier University
Year: 2020

description: Over the past decade, social media has been used by the police to aid police activity and to enhance its reputation. Central to these considerations is police legitimacy, as the police require the cooperation and compliance of citizens for policing to be effective. Accordingly, the current study examined police legitimacy and social media in Scotland. Fieldwork was carried out between November 2016 and September 2017 across three case study locations in Scotland. A range of methods were used, including: participant observation (n=134 hours) and semi-structured interviews (n=40) with police officers and police staff; focus groups with citizens (n=22); and online analysis of the social media platform Twitter (including five police Twitter accounts).
The research findings demonstrate that police legitimacy on social media is understood by police officers, police staff, and citizens in accordance with an interplay between policing in physical and digital spaces, power dynamics, and interactions between instrumental (to do with tackling crime and increasing safety) and normative models of policing (how people are treated). This study makes three original and significant contributions to knowledge. Firstly, the study confirms Bottoms and Tankebe’s (2012) dialogic approach to police legitimacy, and provides an empirical contribution to their notion that police authority is in flux and resembles an ongoing conversation between the police and citizens. Secondly, the study contributes to Bottoms and Tankebe’s (2012) notion of power- holder legitimacy by showing that power is contested within the police organisation in connection to police social media practices, and that citizens have more power over the police on social media. Thirdly, the study contributes knowledge to procedural justice theory by demonstrating that police officers and staff also assess how citizens are procedurally fair towards them during encounters. Procedural justice features alongside perceptions of crime-fighting police roles in police and citizen narratives.

description: To a weighted graph can be associated a bipartite graph planar algebra P. We construct and study the symmetric enveloping inclusion of P. We show that this construction is equivariant with respect to the automorphism group of P. The automorphism group of the weighted graph acts on P. We consider subgroups G of the automorphism group of the weighted graph such that the G-fixed point space P^G is a subfactor planar algebra. As an application we show that if G is amenable, then P^G is amenable as a subfactor planar algebra. We define the notions of a cocycle action of a Hecke pair on a tracial von Neumann algebra and the corresponding cross product. We show that a large class of symmetric enveloping inclusions of subfactor planar algebras can be described by such a cross product.

title: The evolutionary iron law of oligarchy
Creators: name: Perret, Cedric
Publisher: name: Edinburgh Napier University
Year: 2020

description: Social hierarchy is a pervasive element of modern societies, yet almost absent before the advent of agriculture during the Neolithic transition. Despite evidence supporting hierarchy as a product of evolution, it is hard to explain the mechanisms which drove this evolution. For instance, the evolution of followers appears as a paradox because followers receive fewer resources than leaders. The “iron law of oligarchy” proposes that the key to the Neolithic transition lies in the role of leaders in collective decision-making. First, leaders would emerge in response to an increase in group size because leaders speed up decision-making and facilitate coordination. Then, leaders would use their newly acquired inﬂuence to bias opinions and group decisions to impose inequality that beneﬁts themselves. This theory has the beneﬁt of explaining the origin of both beneﬁcial and despotic sides of leaders. Yet, its investigation has been limited because of the lack of a formal description of (i) how individuals change with time and (ii) how individuals take collective decisions. Thus, we propose the evolutionary iron law of oligarchy, which reinterprets the iron law in evolutionary terms. We reduce leaders and followers to their capacity to inﬂuence and we claim that describing the evolution of this trait under the environmental changes observed at the Neolithic transition is sufﬁcient to explain the emergence of helpful and despotic leaders. To investigate this claim, we build individual-centred models simulating consensus formation — how individuals take collective decisions —and evolutionary dynamics — how individuals change with time. On one hand, our results show that the evolutionary iron law of oligarchy is a viable scenario, which can unify previous theories explaining either the beneﬁcial or despotic side of leaders. On the other hand, we developed a mechanistic model of the iron law of oligarchy which can apply across a range of scenarios, and which show under which conditions the iron law of oligarchy would apply. Finally, our results demonstrate that the iron law of oligarchy goes beyond political sciences and is underwritten by the laws of Darwinian evolution. Understanding the factors driving the emergence of hierarchy and despotism will open new perspectives to design better forms of governance.

description: Ptilotis gracilis imitatrix Mathews Ptilotis gracilis imitatrix Mathews, 1912a: 403 (North Queensland (Cairns)). Now Meliphaga gracilis imitatrix (Mathews, 1912). See Schodde and Mason, 1999: 261–262, Christidis and Boles, 2008: 185–191, and Higgins et al., 2008: 592. HOLOTYPE: AMNH 695868, adult male, collected at Cairns, 16.51S, 145.43E (Times Atlas), Queensland, Australia, in October 1909, by P. Schraeder. From the Mathews Collection (no. 3157) via the Rothschild Collection. COMMENTS: Mathews gave his catalog number of the holotype in the original description and the range of imitatrix as ‘‘ North Queensland.’’ In addition to the Mathews Collection label, the holotype bears Mathews and Rothschild type labels and a ‘‘ Figured’ ’ label indicating that it was illustrated in Mathews (1924: pl. 528, upper fig., opp. p. 430, text p. 434) where it is confirmed as the type of imitatrix. The following specimens were in the Mathews Collection before imitatrix was published on 31 January 1912 and are paratypes: AMNH 695859, female, Johnstone River on 22 June 1900, by E. Olive; AMNH 695865 (Mathews’ no. 9537), female, Barron River, 26 July 1910, by the Dodds; AMNH 695869 (3158), female, Cairns, July 1908, by P. Schraeder. AMNH 695867 (10285), sex?, Barron River, 26 July 1910, by the Dodds, was perhaps in Mathews’ hands when the name was published, but it was not cataloged until 13 February 1912. I have considered AMNH 695859 a paratype, although I did not find it in Mathews’ catalog; Mathews purchased Olive’s collection from Robinson and cataloged it in 1910. AMNH 695870, collected at Cairns in 1888 by T.H. Bowyer Bower was not cataloged by Mathews until 1913. Other specimens of this form now in AMNH, either were never in Mathews’ Collection or were collected after the date of publication of the name.

description: We undertake a systematic study of the so-called $2$-adic ring $C^*$-algebra $\mathcal{Q}_2$. This is the universal $C^*$-algebra generated by a unitary $U$ and an isometry $S_2$ such that $S_2U=U^2S_2$ and $S_2S_2^*+US_2S_2^*U^*=1$. Notably, it contains a copy of the Cuntz algebra $\mathcal{O}_2=C^*(S_1, S_2)$ through the injective homomorphism mapping $S_1$ to $US_2$. Among the main results, the relative commutant $C^*(S_2)'\cap \mathcal{Q}_2$ is shown to be trivial. This in turn leads to a rigidity property enjoyed by the inclusion $\mathcal{O}_2\subset\mathcal{Q}_2$, namely the endomorphisms of $\mathcal{Q}_2$ that restrict to the identity on $\mathcal{O}_2$ are actually the identity on the whole $\mathcal{Q}_2$. Moreover, there is no conditional expectation from $\mathcal{Q}_2$ onto $\mathcal{O}_2$. As for the inner structure of $\mathcal{Q}_2$, the diagonal subalgebra $\mathcal{D}_2$ and $C^*(U)$ are both proved to be maximal abelian in $\mathcal{Q}_2$. The maximality of the latter allows a thorough investigation of several classes of endomorphisms and automorphisms of $\mathcal{Q}_2$. In particular, the semigroup of the endomorphisms fixing $U$ turns out to be a maximal abelian subgroup of ${\rm Aut}(\mathcal{Q}_2)$ topologically isomorphic with $C(\mathbb{T},\mathbb{T})$. Finally, it is shown by an explicit construction that ${\rm Out}(\mathcal{Q}_2)$ is uncountable and non-abelian.

description: The rapid growth of the world wide PV market has led to increasing average system size. This development has attracted large and institutional investors to finance large scale PV projects. In many countries, PV installations on roof tops are preferred due to limited land availability and grid connection issues for ground mounted installations and higher feed-in tariffs for roof top or building integrated PV installations. Flat roofs, being the largest roof space available world wide, build an attractive market segment for investors and project developers.
This paper will discuss decision factors for the most suitable PV solution on large flat roofs with different module and installation technologies. The article compares UNI-SOLAR® a-Si triple-junction PV laminates installed at nearly horizontal tilt with the crystalline silicon modules using an optimal tilt. The comparison is done for actual systems installed in two different locations, one in central Europe (Lugano, Alps) and the other one in a sea climate in USA (Santa Cruz, California).

description: We show that the black hole binary (BHB) coalescence rates inferred from the advanced LIGO (aLIGO) detection of GW150914 imply an unexpectedly loud GW sky at milli-Hz frequencies accessible to the evolving Laser Interferometer Space Antenna (eLISA), with several outstanding consequences. First, up to thousands of BHB will be individually resolvable by eLISA; second, millions of non resolvable BHBs will build a confusion noise detectable with signal-to-noise ratio of few to hundreds; third -- and perhaps most importantly -- up to hundreds of BHBs individually resolvable by eLISA will coalesce in the aLIGO band within ten years. eLISA observations will tell aLIGO and all electromagnetic probes weeks in advance when and where these BHB coalescences are going to occur, with uncertainties of <10s and <1deg^2. This will allow the pre-pointing of telescopes to realize coincident GW and multi-wavelength electromagnetic observations of BHB mergers. Time coincidence is critical because prompt emission associated to a BHB merger will likely have a duration comparable to the dynamical time-scale of the systems, and is only possible with low frequency GW alerts.

title: Constructing the moral framework of hospitality in non-commercial homestays
Creators: name: Moysidou, Gesthimani
Publisher: name: Edinburgh Napier University
Year: 2020

description: In the past few years there has been a rise in people trying to find more meaningful ways to experience a country and its local culture when travelling, such as non-commercial homestays. Non-commercial homestays refer to the encounters where food and accommodation are offered by the host in exchange for a few hours of daily work by the guest. Due to the complicated nature of this encounter where the private and the public arena overlap, with the host simultaneously being an employer and the guest being an employee, the rules of the exchange are often unclear. This study explores the ways in which the two sides of non-commercial homestays construct the moral framework of the encounter by reacting to micro-ethical dilemmas they are faced with throughout their experience.
To that end, a combination of an autoethnographic account and in-depth semistructured interviews were employed. For the former, I participated in a Workaway an exchange as a guest to sensitise myself as a researcher to the experience. The autoethnography was followed by 50 interviews with hosts and guests in this setting, participating in au pairing and exchanges facilitated by organisations such as WWOOF, Workaway and HelpX.
The findings suggest that the main aspects of the exchange were the work offered by the guest, the hospitality offered by the host as well as the interpersonal relationship, education and cultural exchange that take place. Each side enters the encounter with their own perceptions of fairness in relation to these aspects and is often faced with micro-ethical dilemmas; situations where they were uncertain of what the moral framework dictates. Their reactions to these dilemmas communicate their viewpoint to the other side explicitly or implicitly- and, in turn, feed into the moral framework of the encounter according to which they will act for the duration of the experience.
In terms of theoretical contributions, the study offers an insight into the host-guest relationship, the resulting power dynamic, as well as the negotiation that takes place between the two throughout the encounter. In terms of practical contributions, the findings of this research can be used by both organisations and their members that participate in such encounters to secure better host-guest matches and ensure a positive experience for both sides.
Stueckelberg massive electromagnetism in curved spacetime: Hadamard renormalization of the stress-energy tensor and the Casimir effect

description: We discuss Stueckelberg massive electromagnetism on an arbitrary four-dimensional curved spacetime (gauge invariance of the classical theory and covariant quantization, wave equations for the massive spin-1 field $A_μ$, for the auxiliary Stueckelberg scalar field $Φ$ and for the ghost fields $C$ and $C^\ast$, Ward identities, Hadamard representation of the various Feynman propagators and covariant Taylor series expansions of the corresponding coefficients). This permits us to construct, for a Hadamard quantum state, the expectation value of the renormalized stress-energy tensor associated with the Stueckelberg theory. We provide two alternative but equivalent expressions for this result. The first one is obtained by removing the contribution of the "Stueckelberg ghost" $Φ$ and only involves state-dependent and geometrical quantities associated with the massive vector field $A_μ$. The other one involves contributions coming from both the massive vector field and the auxiliary Stueckelberg scalar field, and it has been constructed in such a way that, in the zero-mass limit, the massive vector field contribution reduces smoothly to the result obtained from Maxwell's theory. As an application of our results, we consider the Casimir effect outside a perfectly conducting medium with a plane boundary. We discuss the results obtained using Stueckelberg but also de Broglie-Proca electromagnetism and we consider the zero-mass limit of the vacuum energy in both theories. We finally compare the de Broglie-Proca and Stueckelberg formalisms and highlight the advantages of the Stueckelberg point of view, even if, in our opinion, the de Broglie-Proca and Stueckelberg approaches of massive electromagnetism are two faces of the same field theory.

hours of exposition to sunlight. An adequate knowledge of the stabilized modules maximum power is prior for the
correct power rating of modules based on their flash report at factory. Even when LID is described by the well-known
Staebler-Wronski effect, there are many factors that affect this process under real world conditions. This work
presents an extensive study of LID based on industrial manufactured a-Si:H photovoltaic modules using several
recipes for the deposition of layers. The degradation has been done in natural light conditions and the evaluation
using two complementary methodologies. Through this testing, LID caused by Staebler-Wronski effect is
characterized in terms of the modules characteristic parameters.

description: Through this portfolio of compositions I aim to explore the significance of text in my compositional process, whether recited or not. In String Quartet No.2 poetry is a vital means of compositional stimulus with the structure of the text as well as its imagery in terms of affect and perceived sound effects garnering musical material. Similarly in the work Horo, working with two poets, new texts were created with the foundations of these deriving from the original folksong and its text, Turn Ye To Me. Furthermore, Totentanz deals with aspects of deconstruction and parody, both in terms of textual deconstruction from the written word to phonetic sound, and also cognitive deconstruction regarding the semantics of Goethe’s poetic work.
Furthermore, the following commentary will detail the interaction I as a composer have with three significant factors during the creative process: the performers, the audience, and the location of the work’s performance. The work for chamber choir and organ, A Song to David, takes into account the various constraints that are present when composing for young or amateur musicians, for example vocal range and balance between voice parts. My interaction with the audience relies on a number of aspects, namely whether the work is to be heard in a concert setting or for an act of celebration or worship, and also the effective communication of text and/or affect. Finally, in terms of performance location, my work considers the acoustic of the building and the position of the performers within it. Five Introits demonstrates this with each introit being composed to exploit the resonance of the building as well as the positioning of the choir. It is through these three distinct considerations that the role of composer as facilitator is explored with regard to the commissioning process.

description: Photovoltaic energy development in Spain has been related to the feed in tariffs energy strategic. Since
1998 several regulatory frameworks has been established to enhance the incorporation of the new technologies, its
developing and the cost reduction of the energy generation, in order to reach Grid Parity. It has been based on
economic incentives with the consequent market growth and sometimes without a correct management of market
rules. In the last few years Spain has been a photovoltaic energy reference, especially between 2007 and 2008,
producing an international technology improvement but assuming these processes cost. Finally, the new Photovoltaic
Royal Decree 1578/2008 has been established to get a sustainable development, and it has produced an adjustment of
the market and the national industry. In a short period of time a new PV Royal Decree will be available with more
regulation measures.

description: We simulate neutralino dark matter ($χ$DM) haloes from their initial collapse, at $\sim$ earth mass, up to a few percent solar. Our results confirm that the density profiles of the first haloes are described by a $\sim r^{-1.5}$ power-law. As haloes grow in mass, their density profiles evolve significantly. In the central regions, they become shallower and reach on average $\sim r^{-1}$, the asymptotic form of an NFW profile. Using non-cosmological controlled simulations, we observe that temporal variations in the gravitational potential caused by major mergers lead to a shallowing of the inner profile. This transformation is more significant for shallower initial profiles and for a higher number of merging systems. Depending on the merger details, the resulting profiles can be shallower or steeper than NFW in their inner regions. Interestingly, mergers have a much weaker effect when the profile is given by a broken power-law with an inner slope of $-1$ (such as NFW or Hernquist profiles). This offers an explanation for the emergence of NFW-like profiles: after their initial collapse, $r^{-1.5}$ $χ$DM haloes suffer copious major mergers, which progressively shallows the profile. Once an NFW-like profile is established, subsequent merging do not change the profile anymore. This suggests that halo profiles are not universal but rather a combination of (1) the physics of the formation of the microhaloes and (2) their early merger history -- both set by the properties of the dark matter particle -- as well as (3) the resilience of NFW-like profiles to perturbations.

description: Ptilotis analoga mixta Mathews Ptilotis analoga mixta Mathews, 1912a: 403 (North Queensland (Johnston [sic] River)). Now Meliphaga notata mixta (Mathews, 1912). See Schodde and Mason, 1999: 259–260, Christidis and Boles, 2008 185–191, and Higgins et al., 2008: 589–590. HOLOTYPE: AMNH 695989, adult male, collected on the Johnstone (not Johnston) River, 17.31S, 146.03E (Storr, 1984: 183), Queensland, Australia, by E. Olive, on 22 June 1900. From the Mathews Collection (no. 4247) via the Rothschild Collection. COMMENTS: Mathews cited his catalog number of the holotype in the original description, giving the range of the form as ‘‘ North Queensland.’’ The holotype bears, in addition to Olive’s original label, Mathews and Rothschild type labels and a ‘‘ Figured’ ’ label, indicating that it was illustrated in Mathews (1924:pl. 528, lower fig., opp. p. 430, text p. 430) where it is confirmed as the type of mixta. Paratypes in AMNH are: AMNH 695998 (Mathews no. 3154), female, Cairns, 10 November 1904, apparently received on exchange from the Royal Scottish Museum in 1908; AMNH 696003 (5040), sex?, Kuranda, 13 May 1910, by the Dodds; AMNH 696004 (3156), male, Cooktown, 31 May1898, by Olive. Other specimens either were not in Mathews’ Collection or were collected after the publication date of mixta on 31 January 1912. AMNH 695997, collected on the Barron River in 1884 by T.H. Bowyer Bower was not cataloged by Mathews until 1913. One additional paratype that did not come to AMNH was cataloged by Mathews as no. 5041, collected on the Barron River on 7 June 1910 by the Dodds.

description: Electron correlation in graphene is unique because of the interplay of the Dirac cone dispersion of $π$ electrons with long range Coulomb interaction. The random phase approximation predicts no metallic screening at long distance and low energy because of the zero density of states at Fermi level, so one might expect that graphene should be a poorly screened system. However, empirically graphene is a weakly interacting semimetal, which leads to the question of how electron correlations take place in graphene at different length scales. We address this question by computing the equal time and dynamic structure factor $S(\vec q)$ and $S(\vec q, ω)$ of freestanding graphene using {\it ab-initio} fixed-node diffusion Monte Carlo and the random phase approximation. We find that the $σ$ electrons contribute strongly to $S(\vec q,ω)$ for relevant experimental values of $ω$ even at distances up to around 80 Å. These findings illustrate how the emergent physics from underlying Coulomb interactions results in the observed weakly correlated semimetal.

description: The variation of the generation output of large-scale PV is said to substantially affect the power system
demand-supply balance to incur frequency fluctuation and difficulties of load generation dispatch operation. The issues are
expected to be fixed through the combination of the quantitative analysis and evaluation of the variation of the TOTAL PV
generation output in a generation dispatch control area, and enhancement of generation control capability generation dispatch
operation, and deployment new technologies such as enhanced demand response and energy storage. In this paper, the power
system demand-supply balance planning including substantial PV penetration for 2030 in Japan is presented.
title: An exploration of how academic staff construct social identities in the career transition from the performing arts into higher education
Creators: name: Miller Judd, Pauline Claire
Publisher: name: Edinburgh Napier University

description: For delivery of practice-based degrees in performing arts, universities often seek to employ lecturers with a strong professional profile which is considered to add value to the student experience. The transition from performing arts to academia is a major event in the development of social identity and this study was designed both to explore the social identities of staff who have transitioned from performing arts careers to academic roles in higher education and to examine key influences on their process of social identity categorisation.
The study involved in-depth narrative interviews to explore participants’ social identity in both the performing arts and higher education with insights drawn over the course of participants’ lives. A range of potential patterns were identified in the participants’ narratives with regards to the construction of their social identities in career transition. The findings were evaluated and a set of recommendations made for stakeholders.
Key findings emerged regarding the value of formal and informal socialisation in career transition and a variation in perceptions of prototypical academic identities. Examples of social creativity by participants was observed, along with examples of social mobility and competition. The key finding in relation to social identity theory was that participants were observed to have a high salience in their performing arts social identity and broad patterns of layered multiple social identities were observed.

description: Multicrystalline silicon blocks, intentionally contaminated with iron and copper, had been cast and
characterized by the twelve German research institutes working together with twelve German companies in the
network project SolarFocus. The results of the lifetime measurements, NAA, FTIR analysis, DLTS/MCTS
investigations, determination and simulation of the Fei content, solar cell processing, shunt and microscopic
investigations are presented in this paper. The combined analysis reveals the influence of the in-diffusion of metal
impurities from the crucible as well as the back-diffusion from the top region of the block. Solar cell efficiency is
influenced by multiple recombination active defects as well as shunts induced by a high metal contamination.

description: Heterogeneous bipartite quantum pure states, composed of two subsystems with a different number of levels, cannot have both reductions maximally mixed. In this work, we demonstrate existence of a wide range of highly entangled states of heterogeneous multipartite systems consisting of $N>2$ parties such that every reduction to one and two parties is maximally mixed. Two constructions of generating genuinely multipartite maximally entangled states of heterogeneous systems for an arbitrary number of subsystems are presented. Such states are related to quantum error correction codes over mixed alphabets and mixed orthogonal arrays. Additionally, we show the advantages of considering heterogeneous systems in practical implementations of multipartite steering.
