description: We prove homogenization properties of random Hamilton--Jacobi--Bellman (HJB) equations on continuum percolation clusters, almost surely w.r.t. the law of the environment when the origin belongs to the unbounded component in the continuum. Here, the viscosity term carries a degenerate matrix, the Hamiltonian is convex and coercive w.r.t. the degenerate matrix and the underlying environment is non-elliptic and its law is non-stationary w.r.t. the translation group. We do not assume uniform ellipticity inside the percolation cluster, nor any finite-range dependence (i.i.d.) assumption on the percolation models and the effective Hamiltonian admits a variational formula which reflects some key properties of percolation. The proof is inspired by a method of Kosygina--Rezakhanlou--Varadhan developed for the case of HJB equations with constant viscosity and uniformly coercive Hamiltonian in a stationary, ergodic and elliptic random environment. In the non-stationary and non-elliptic set up, we leverage the coercivity property of the underlying Hamiltonian as well as a relative entropy structure (both being intrinsic properties of HJB, in any framework) and make use of the random geometry of continuum percolation.

description: The metastable effects in Cu(In,Ga)Se2-based heterojunction thin-film solar cells are still not
completely understood. In this study long term stability tests under different voltage bias and illumination at
elevated temperature are presented. The results of I-V and C-V measurements indicate a change of net acceptor
concentration in the bulk which is partly responsible for the parameter drift of the open circuit voltage. As a
consequence of that an accumulation of negative charges at the heterointerface leads to a change of the fill
factor. EL-measurements furthermore show a change of the luminescence efficiency (LED quantum efficiency)
which is also partly responsible for the observed parameter drift of the Voc. Responsible for the light soak effect
are not the generated electron hole pairs but rather the position of the quasi Fermi levels in the space charge
region. We propose a qualitative model which explains both effects the loss of VOC and ff by one phenomenon.
The parameter drift of the Voc is a bulk effect and is a consequence of the variation of the net doping density and
of the luminescence efficiency. The shift of the ff is related to an accumulation of negative charges at the
heterointerface which also depends on bulk properties in our model. We also present possibilities to optimize
CIGS modules under field conditions to raise the yield of the harvested power.

title: Exploring internationalisation and development strategies of the largest privately-owned breweries in Germany
Creators: name: Seiss, Julia Maria
Publisher: name: Edinburgh Napier University
Year: 2022

description: This study investigates strategic changes in internationalisation modes of privately-owned German breweries and brewery groups and the underlying causes which indicate how and when change is brought about.

Severe difficulties and competitive pressure in the home-market force German breweries to internationalise more intensely. Even though some German breweries have established substantial business abroad, further developments, in particular internationalisation mode changes, are perceived as challenging task. There are several models in internationalisation literature, which were established to guide this change. The most dominant one is the Uppsala model of internationalisation. However, a literature review has shown that there are major points of criticism related to the model when it comes to a number of state aspects and change variables. As many influential factors are neglected in the model its practical applicability is very limited. Subsequent research has also proven that the model depicts a rather theoretical approach to increasing international involvement. Thus, the qualitative approach of this study aimed at identifying these underlying factors which impact change in practice. Based on a constructivist paradigm, expert interviews allowed to collect narratives of individuals in the industry. The subsequent analysis has shown that there is a much greater variety of internationalisation modes than originally suggested and that the impact of internal determinants, such as culture, organisational processes, and people, were perceived as dominant influences on the outcome of internationalisation mode changes of German breweries. Thus, as opposed to the current state of literature around the Uppsala model, market factors only played a subordinate role in the internationalisation process. These valuable findings now allow to make more accurate predictions of the (non-)incrementality and speed and timing of movement through the model. Once the critical state aspects are available in a suitable depth and amount, the next step in the internationalisation process can be taken. Therefore, the determinants in the current U-model were adjusted in order to suit the internationalisation behaviour of privately-owned German breweries. In doing so, breweries can move faster and more efficiently through a pro-active internationalisation mode change process and secure their long-term success in international markets.

description: In the convergence analysis of numerical methods for solving partial differential equations (such as finite element methods) one arrives at certain generalized eigenvalue problems, whose maximal eigenvalues need to be estimated as accurately as possible. We apply symbolic computation methods to the situation of square elements and are able to improve the previously known upper bound, given in "p- and hp-finite element methods" (Schwab, 1998), by a factor of 8. More precisely, we try to evaluate the corresponding determinant using the holonomic ansatz, which is a powerful tool for dealing with determinants, proposed by Zeilberger in 2007. However, it turns out that this method does not succeed on the problem at hand. As a solution we present a variation of the original holonomic ansatz that is applicable to a larger class of determinants, including the one we are dealing with here. We obtain an explicit closed form for the determinant, whose special form enables us to derive new and tight upper resp. lower bounds on the maximal eigenvalue, as well as its asymptotic behaviour.

description: It is important for the assessment of the economic profitability of a new cell concept to be able to
compare it to conventional types. Metal wrap through (MWT) cells yield larger currents than standard cells owing to
their reduced front metal coverage. Currently, the predictions of the efficiency gain of MWT cells compared to
conventional H-pattern cells span a large range. Apart from the specific design variations, the reason for this
uncertainty is that a comparison of cell efficiencies between cells of different types is not straight forward but
requires a good understanding of the measurements and accompanied errors. As the absolute errors of two different
calibrated reference cells add up to large inaccuracies for the comparison, we introduce the concept of a single hybrid
reference cell. This way, a much better accuracy is achieved. Finally, we compare the performance of MWT and Hpattern
cells on the basis of experimental data on cell and module level.

description: Conventional supersymmetry searches rely on large missing momentum and, on that account, are unsuitable for discovering superpartners nearly degenerate with the LSP. Such "compressed regions" are best probed by dedicated strategies that exploit their unique kinematic features. We consider a case study of a compressed gluino-bino simplified spectrum, motivated by its ability to set the dark matter relic abundance via co-annihilation. A kinematic variable suited to this spectrum is introduced, by which, for a gluino-bino mass splitting of 100 GeV, the discovery reach is extendable to m(gluino) = 850 GeV (1370 GeV) at LHC center-of-mass energy 8 TeV (13 TeV) with luminosity 20 inverse fb (3000 inverse fb). The non-trivial role played by soft triggers is also discussed.

title: Advanced nickel barrier coatings: Manufacturing process and properties
Creators: name: Rumbles, Michael
Publisher: name: Edinburgh Napier University
Year: 2022

description: New-generation protective coatings should respond to mechanical or chemical damage with active corrosion inhibition, preserving coating integrity and adhesion to the substrate. Due to the implementation of legislation imposed by REACH (Restriction, Evaluation, Authorisation & restriction of Chemicals), restrictions have been placed on the use of chromium (VI) compounds, which were the main components of self-healing anti-corrosion coatings. Having similar properties, e.g. wear and corrosion resistance, nickel-phosphorous coatings might be one possible replacement for coatings containing Cr6+ .

The novel work carried out during this research programme has focused on developing a process to include corrosion inhibitors within nickel-phosphorus coatings using the electroless co-deposition technique. Gelatine and sodium alginate microgels were investigated for their feasibility at this task. It was found that gelatine microgels of average diameter 2–6 μm, heat-treated at 150 °C for 15 hours exhibited the desired properties to survive the co-deposition process at 89 °C in acidic electroless nickel solutions operating at 4.9 pH.

Depositions on ISO 3574 Type CR1 steel were performed to determine the impact on the coating properties due to the inclusion of gelatine microgels. The microgels were produced without the inclusion of active corrosion inhibitors at this time. Various deposition parameters were investigated, and it was determined that the addition of small quantities, below 0.05 g/L, provided the best depositions. Above 0.1 g/L, the microgels would block the reaction sites required for the electroless deposition process which led to poor quality coatings and a reduction in deposition rate from 20 μm to 1.5 μm/hr.

The resulting novel coatings were investigated using a series of empirical and quantitative tests. The results of this study show that the coatings with gelatine microgels show increased phosphorus content, and a reduction in the surface hardness and abrasion resistance of the coatings. The corrosion studies show that the inclusion of gelatine microgels impacts the corrosion resistance of the coatings even when no additional corrosion inhibitors are included.

description: Museums are centres of learning. They play a significant role in the projection of cultural and natural heritage and can increase awareness among the masses. When it was established in 1951, academics in several departments at the University of Karachi felt the need for a Museum. Funds were raised and material was collected to set up educational museums for the instruction of students. At present the museums of the Botany, Geology, Geography, General History, Sociology, and Zoology Departments are well-nigh dormant. There are several reasons for this, such as organizational and administrative neglect, lack of funds, lack of upgrading, and lack of an adequate programme to attract students. The aim of this paper is to clarify the causes of this deplorable situation and to develop ideas for future improvement.

description: The main objective of the national project “Espectro Solar” is the selection and installation of
appropriate spectroradiometers to measure the solar spectrum at three different locations in Spain and to provide a
reliable database of direct and global solar spectral data. Within this work, the preliminary results of the project
focusing on long-term measurements of the solar spectrum in several Spanish locations are discussed. The
measurements were obtained from devices which were installed in Seville with Abengoa Solar New Technologies
(ASNT) and Concentrix Solar. In Puertollano, the solar spectrum measurement system by the Instituto de Sistemas
Fotovoltaicos de Concentración (ISFOC) is presented. And finally one system is investigated by the Instituto de
Energía Solar (IES) in Madrid. A set of guidelines that describe how to select suitable equipment for long-term
outdoor measurements is introduced. The verification processes of the corresponding equipments, carried out by the
Instituto Nacional de Técnica Aeroespacial (INTA), are explained. Finally a considerable improvement of
Concentrix Solar's FLATCON® module efficiency is reported, caused by the reduction of spectral losses.

description: We study the logarithmic negativity and the moments of the partial transpose in the ground state of a two dimensional massless harmonic square lattice with nearest neighbour interactions for various configurations of adjacent domains. At leading order for large domains, the logarithmic negativity and the logarithm of the ratio between the generic moment of the partial transpose and the moment of the reduced density matrix at the same order satisfy an area law in terms of the length of the curve shared by the adjacent regions. We give numerical evidences that the coefficient of the area law term in these quantities is related to the coefficient of the area law term in the Rényi entropies. Whenever the curve shared by the adjacent domains contains vertices, a subleading logarithmic term occurs in these quantities and the numerical values of the corner function for some pairs of angles are obtained. In the special case of vertices corresponding to explementary angles, we provide numerical evidence that the corner function of the logarithmic negativity is given by the corner function of the Rényi entropy of order 1/2.

description: The presence of defect clusters in multicrystalline silicon – not only in compensated silicon – can
influence the electronic properties of solar cells. This is due to the interfered further crystallization and an insufficient
passivation of the defects in these regions. Three-dimensional plots, based on hundreds of electroluminescence images,
allow an improved analysis of the defect clusters’ growth during crystallization. Furthermore, this allows vertical views
from any angle which is otherwise only possible with destructive vertical cuts.

description: Vacuum rectification of highly doped N-type EG-silicon (As: 200 ppma) was conducted with use of
electron beam as a heater. When background impurities' level for laboratory equipment was defined processes with
varying power of electron beam were conducted in temperature range from melting point to the point of container
destruction. Effective temperature of melt surface was calculated and it was revealed that temperature should be
considerably higher than melting temperature, but it should enable container to be used for long period of time (not
less than 1 hour) without container destruction. Increase of power and loads' mass further than 15 kgs led to
contamination of silicon with metal impurities. We managed to avoid problems with container destruction and
insertion of metal impurities while shifting to 50 kg s load thanks to improvements in technological process of
purification and furnace design. Several CZ monocrystals (6”, P-type,  > 1 Ohm*cm,  > 10 μs) were successfully
grown from material obtained in 50 kgs load processes. According to our estimations, such purification effect was
achieved at effective temperature of melt surface ca 2000K.

description: Core collapse supernovae (CCSNe) are important sources of interstellar dust, potentially capable of producing one solar mass of dust in their explosively expelled ejecta. However, unlike other dust sources, the dust has to survive the passage of the reverse shock, generated by the interaction of the supernova blast wave with its surrounding medium. Knowledge of the net amount of dust produced by CCSNe is crucial for understanding the origin and evolution of dust in the local and high-redshift universe. Our aim is to identify the dust destruction mechanisms in the ejecta, and derive the net amount of dust that survives the passage of the reverse shock. We use analytical models for the evolution of a supernova blast wave and of the reverse shock, with special application to the clumpy ejecta of the remnant of Cassiopeia A. We assume that the dust resides in cool oxygen-rich clumps that are uniformly distributed within the remnant and surrounded by a hot X-ray emitting plasma, and that the dust consists of silicates (MgSiO3) and amorphous carbon grains. The passage of the reverse shock through the clumps gives rise to a relative gas-grain motion and also destroys the clumps. Inside the ejecta clouds, dust is processed via kinetic sputtering, which is terminated either when the grains escape the clumps, or when the clumps are destroyed by the reverse shock. In either case, grain destruction proceeds thereafter by thermal sputtering in the hot ambient gas. We find that 11.8% and 15.9% of, respectively, the silicate and carbon dust survives the passage of the reverse shock by the time the shock has reached the center of the remnant. These fractions depend on the morphology of the ejecta and the medium into which the remnant is expanding, as well as the composition and size distribution of the grains that formed in the ejecta. Results will therefore differ for different types of supernovae.

description: This paper presents a design and simulation of a SEPIC/CUK converter used in Maximum power point
tracker of the PV System. The Maximum Power Point Tracker maximizes the output power of a photovoltaic array to
the load under varying meteorological conditions. The majority of the available techniques employ either Buck,
Boost or Buck-boost DC-DC converters in the conversion stage for optimizing the power output to the load. This
paper presents the design of SEPIC/Cuk Converter which are operated in Discontinuous Induction current Mode or in
discontinuous capacitor voltage mode to extract Maximum power from a PV panel. The maximum power to the load
is delivered by making the input resistance of the converter equal to the output resistance of the panel by adjusting
the duty ratio of the Converter. The scheme is simulated on PSpice using a diode model for a 75 watt Solar Panel and
system study is carried out using Simulink. The model parameter of the Panel is extracted by experimentally
measuring V-I characteristics of the panel using an indigenously developed PC based test bed. The tracking
capabilities of the proposed technique are verified by simulation under wide range of varying meteorological
condition.

description: The Auto-Importance Sampling (AIS) method is a Monte Carlo variance reduction technique proposed for deep penetration problems, which can significantly improve computational efficiency without pre-calculations for importance distribution. However, the AIS method is only validated with several simple examples, and cannot be used for coupled neutron-photon transport. This paper presents the improved algorithms for the AIS method, including particle transport, fictitious particles creation and adjustment, fictitious surface geometry, random number allocation and calculation of the estimated relative error. These improvements allow the AIS method to be applicable to complicated deep penetration problems with complex geometry and multiple materials. A coupled Neutron-Photon Auto-Importance Sampling (NP-AIS) method is proposed to solve the deep penetration problems of coupled neutron-photon transport using the improved algorithms. The NUREG/CR-6115 PWR benchmark was calculated by using the methods of NP-AIS, geometry splitting with Russian roulette and the analog Monte Carlo, respectively. The calculation results of NP-AIS were in good agreement with those of geometry splitting with Russian roulette and the benchmark solutions. The computational efficiency of NP-AIS for both neutron and photon was much better than that of geometry splitting with Russian roulette in most cases, and increased by several orders of magnitude compared with that of the analog Monte Carlo.

title: Synthesis and fluorescence properties of a novel legumain substrate probe
Creators: name: Ravula, Deepthi
Publisher: name: Edinburgh Napier University
Year: 2022

description: Despite great advancement in the diagnosis and treatment of many cancers, mortality rates remain high and the incidence of some forms of cancer is increasing.

Early diagnosis is recognised as an important factor to increase survival but there is currently a lack of reliable biomarkers of disease.

The focus of this research is the development of a new molecular probe for the putative cancer biomarker legumain (asparaginyl endoprotease) which is overexpressed in a wide variety of cancers and has been proposed as a viable biomarker of disease progression.

A novel FRET peptide substrate AQ(4-OH)-β-Ala-Pro-Ala-Asn-γ-Abu-piperazine-Rho (DR21) for legumain was designed with a peptide sequence containing a critical asparagine residue (cleavage site) at the P1 position for recognition and cleavage by the target enzyme. Uniquely, the N-terminus was capped by an aminoanthraquinone quencher (acceptor) group and a rhodamine B-derived fluorophore was incorporated at the C-terminus. DR21 was characterised by high resolution mass spectrometry and by NMR spectroscopy and efficient quenching of rhodamine fluorescence was demonstrated.

Proof of principle was demonstrated by fluorescence spectroscopy. DR21 was activated upon incubation with recombinant human legumain with concomitant release of intense rhodamine fluorescence consistent with legumain-induced activation of the fluorogenic probe. The ability to release a hydrophobic derivative of rhodamine has potential advantages over existing fluorogenic substrates due to possessing structural features to allow entry to cells to aid imaging for tumours that express legumain.

description: Several commercially available viscosity measurement systems exist on the market. Only few of them
are able to measure viscosities at high shear rates, which reflect the highly dynamic conditions in the sawing channel
during the wire sawing process for slicing silicon wafers. But these mostly oscillation based apparatuses show
disadvantages in both, accuracy because of the separation of abrasives and carrier fluid and in instability, because of
the abrasive nature of the slurry. The newly developed high shear rate viscosity measurement system was setup in
order to simulate the conditions of the wire sawing process and its dimensions. A fast rotating steel disc reflects the
fast moving wire with a peripheral speed of up to 20 m/s. The distance of a few microns between the fast moving wire
and the silicon in the sawing channel is recreated with a small brick closely positioned to the steel disc by a linear
stage. Slurry applied between steel disc and silicon brick is highly sheared during disc rotation. Forces, which apply
to the silicon brick, can be measured by a sensor. This data and the rotation speed of the disc with the gap width
between disc and silicon are the basic measurements in order to calculate the dynamic viscosity of the slurry at
different shear rates of up to 700000 s-1. Furthermore, a tempering system for the slurry can be used to evaluate the
temperature coefficient of the viscosity.

description: Information transfer is an essential factor in determining the robustness of collective behaviour in biological systems with distributed control. The most direct way to study the information transfer mechanisms is to experimentally detect the propagation across the system of a signal triggered by some perturbation. However, for field experiments this method is inefficient, as the possibilities of the observer to perturb the group are limited and empirical observations must rely on rare natural perturbations. An alternative way is to use spatio-temporal correlations to assess the information transfer mechanism directly from the spontaneous fluctuations of the system, without the need to have an actual propagating signal on record. We test the approach on ground truth data provided by numerical simulations in three dimensions of two models of collective behaviour characterized by very different dynamical equations and information transfer mechanisms: the classic Vicsek model, describing an overdamped noninertial dynamics and the inertial spin model, characterized by an un- derdamped inertial dynamics. By using dynamical finite size scaling, we show that spatio-temporal correlations are able to distinguish unambiguously the diffusive information transfer mechanism of the Vicsek model from the linear mechanism of the inertial spin model.

description: In this paper, results concerning the influence of the synthesis conditions on the growth rate, surface
chemistry and structural properties of Zn(O,S) thin films deposited from a chemical bath containing thiourea, zinc
acetate, ammonia and sodium citrate are presented. Kinetic studies revealed that all reagents affect the growth rate. An
approach to law rate of the growth process was also obtained.
XPS (x-ray photoelectron spectroscopy ) analysis showed that during the CBD process, ZnS and Zn(OH)2 are
formed. Beside, XRD (X-ray diffraction) measurements carried out to Zn(O,S) deposited by CBD on CuGaSe2
(CGS) films revealed that these films grow with a mixture of cubic and hexagonal structures.

description: A stable and reproducible method of Na doping for CIGS solar cells can be achieved by depositing
a Na doped molybdenum layer using a MoNa sputtering target. Deposition rate, resistivity and film stress were
determined for MoNa films, sputtered from a 3 at.% Na containing MoNa target. The influence of Ar pressure
and power applied to the cathode was investigated and compared with data for pure Mo. An improvement of the
cell efficiency in comparison to a Na free reference sample is shown for CIGS solar cells processed on polyimide
substrate and using a MoNa layer below the Mo back contact. The MoNa sputtering targets made by PLANSEE
by a powder metallurgical process offer a defined Na content, high density, high purity and homogeneity.
Odd-frequency Superconductivity in Driven Systems

description: We show that Berezinskii's classification of the symmetries of Cooper pair amplitudes holds for driven systems even in the absence of translation invariance. We then consider a model Hamiltonian for a superconductor coupled to an external driving potential and, treating the driving potential as a perturbation, we investigate the corrections to the anomalous Green's function, density of states, and spectral function. We find that in the presence of an external drive the anomalous Green's function develops terms that are odd in frequency and that the same mechanism responsible for these odd-frequency terms generates additional features in the density of states and spectral function.

description: Nanosecond laser sources are established in photovoltaic thin-film processing, but there are a lot of
optimization possibilities to achieve better scribing results with regard to the effect of heat influence on the material.
To reduce these effects investigations of the influence of the laser pulse length were made on a typical photovoltaic
thin-film material with picosecond, subnanosecond and nanosecond laser sources. The theoretical background of
laser pulse and material interaction and the thermal penetration depth depending on the laser pulse length are
compared with the experimental results of molybdenum scribing with different laser pulse lengths from 10 picoseconds
to 200 nanoseconds. The analysis takes into account track quality, glass cracks and damages, heat affected
zone and melt formation.

description: As part of the EOSC Task Force on FAIR Metrics and Data Quality, the FAIR Metrics subgroup works
 to examine the uptake and application of metrics of FAIRness and the use and utility of FAIRness
 evaluations. A range of FAIR assessment tools is designed to measure compliance with established
 FAIR Metrics by measuring one or more Digital Objects (DO, including datasets and repositories).
 Unfortunately, the same DO assessment by different tools often exhibits widely different results
 because of independent interpretations of the Metrics, metadata publishing paradigms, and even
 the intent of FAIR itself.
 In response to this status quo, the FAIR Metrics subgroup (represented by the authors of this report)
 brought together developers of several FAIR evaluation tools and enabling services (listed in the
 Acknowledgements) for a series of hands-on hackathon events to identify a common approach to
 metadata provision that could be implemented by all data publishers such as databases,
 repositories, and data catalogue managers. This led to identifying a process for (meta)data
 publishing based on well-established Web standards already in everyday use within data publishing
 communities, albeit not uniformly. A specification document describing the approach and a series
 of “Apples-to-Apples” (A2A1) benchmarks to evaluate compliance with this (meta)data publishing
 approach were created during a series of hackathon events. The authors of FAIR evaluation tools
 also began writing the code to ensure their independent tools would behave identically when
 encountering these A2A benchmark environments, thus helping to ensure that data publishers
 following this paradigm will be evaluated in a harmonized manner by all assessment tools;
 additional considerations for assessment tool harmonization are discussed later. This report
 explains the rationale for these workshop and hackathon events, outlines the outcomes and work
 done, describes the current status, and then discusses desirable next steps. The authors propose
 that the EOSC Association, the EOSC Task Force Long-term Data Preservation, and other groups and
 projects in Europe and worldwide consider this approach to deliver accurate means to all
 stakeholders that assist in achieving FAIRness of research data.

description: We present a way of measuring with high precision the anharmonicity of a quantum oscillator coupled to an optical field via radiation pressure. Our protocol uses a sequence of pulsed interactions to perform a loop in the phase space of the mechanical oscillator, which is prepared in a thermal state. We show how the optical field acquires a phase depending on the anharmonicity. Remarkably, one only needs small initial cooling of the mechanical motion to probe even small anharmonicities. Finally, by applying tools from quantum estimation theory, we calculate the ultimate bound on the estimation precision posed by quantum mechanics and compare it with the precision obtainable with feasible measurements such as homodyne and heterodyne detection on the cavity field. In particular we demonstrate that homodyne detection is nearly optimal in the limit of a large number of photons of the field and we discuss the estimation precision of small anharmonicities in terms of its signal-to-noise ratio.

description: Local failures are crucial factors in the performance of thin-film modules and a thorough understanding of
their effects is essential in predicting and optimizing the module power output.
Using a 2d-network model, we give quantitative estimates of the impact of local inhomogeneties, e.g. structuring
or local layer problems. In this study, the influence of local shunts and local current variability was analyzed.
Several CdTe-modules exhibiting local failures were characterized and the observed local characteristics were
used to set up models for the network simulations.
