description: The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of 56Ni and 56Co, the main radioactive isotopes synthesized by the thermonuclear explosion of a C/O white dwarf. Gamma-rays escaping the ejecta can be used as a diagnostic tool for studying the characteristics of the explosion. In particular, it is expected that the analysis of the early gamma emission, near the maximum of the optical light curve, could provide information about the distribution of the radioactive elements in the debris. In this paper, the gamma data obtained from SN2014J in M82 by the instruments on board of INTEGRAL are analyzed taking special care of the impact that the detailed spectral response has on the measurements of the intensity of the lines. The 158 keV emission of 56Ni has been detected in SN2014J at ~5 sigma at low energy with both ISGRI and SPI around the maximum of the optical light curve. After correcting the spectral response of the detector, the fluxes in the lines suggest that, in addition to the bulk of radioactive elements buried in the central layers of the debris, there is a plume of 56Ni, with a significance of ~3 sigma, moving at high velocity and receding from the observer. The mass of the plume is in the range of ~ 0.03-0.08 solar masses. No SNIa explosion model had predicted the mass and geometrical distribution of 56Ni suggested here. According to its optical properties, SN2014J looks as a normal SNIa. So it is extremely important to discern if it is also representative in the gamma-ray band.

description: This project rethinks architectural work in the context of waste. Fourth-year students designed and built a mobile maker-space at the Repurpose Project, a last stop for cast-off materials before the landfill. This essay argues that the material ecologies found in such places provide a critical context for understanding architectural work as a collective body of knowledge and practical know-how. The rejected and scrapped materials themselves had agency, carrying legacies and future potentialities, not just for the project but also for the larger collaborative project of evaluating and addressing work and waste in and out of academia and the architectural profession. Building the maker-space recast the process of making as a series of critical ecological acts and explored the Repurpose Project model as a knowledge commons for alternative architectural practices.

description: A Luminescent Down-Shifting (LDS) layer is an optical approach to improve the solar cell’s optical response by using luminescent species doped in a polymer matrix material to form a thin layer to be deposited on top of the PV solar cell. In this article, the performance of different polymer matrix materials with various loss mechanisms (attenuation and scattering losses) are mathematically modeled based on a ray tracing algorithm. The simulation is carried out with and without counting the loss mechanisms in the mathematical model. First, the model studied the performance of LDS layer (12.49 × 12.49 × 0.015 cm) of Europium complex (Eu) doped in a Polyvinyl Acetate (PVA) film and deposited on top of monocrystalline Silicon (c-Si) under standard AM1.5 global solar radiation. The
comparison of the modelling and experimental results proved that the model’s discrepancy was improved from 27% to
2% when the loss mechanisms of the matrix materials are counted in the model. Optical efficiency of 80% was obtained
for the LDS layer and an excellent agreement has been achieved between the experimental and model results.
Subsequently, the model was used to study the performance of other matrix materials such as glass, epoxy resin polymer, and Poly Methyl Methacrylate (PMMA) polymer for their loss mechanisms. The results have shown that although these polymer are transparent above 300 nm, their optical response significantly changes in the region between 300 to 400 nm hence the optical efficiency and response of the LDS layer.

description: “Poor but Sexy” is Berlin, in a well-known institutional slogan. The city has experienced a unique evolution since the end of World War II and the Cold War years, attracting creative talents who crafted a metropolitan and cosmopolitan network of fertile connections and exchanges. Berlin appears to be structured in micro-areas: kiez8 is the urban and social unit, a small commons where shared views and actions define the neighbourhood. Since the fall of the Wall, the Berlin community has lived in a multiple-layered town whose dynamics revealed many contradictions, due to the virtual walls and maps that end up opposing to the elaboration of a consistent metropolitan strategy. This article discusses the role of cultural commons in urban development, which do not fit a unique model or mechanism. An effective administrative action can encourage the diffusion and location of creative industries and cultural enterprises, generating a sustainable value chain for Berlin’s identity, based upon cultural commons.

Saturation of number variance in embedded random matrix ensembles

Publisher: name: arXiv
Year: 2015
Subjects: subject: Mathematical Physics (math-ph)

description: We study fluctuation properties of embedded random matrix ensembles of non-interacting particles. For ensemble of two non-interacting particle systems, we find that unlike the spectra of classical random matrices, correlation functions are non-stationary. In the locally stationary region of spectra, we study the number variance and the spacing distributions. The spacing distributions follow the Poisson statistics which is a key behavior of uncorrelated spectra. The number variance varies linearly as in the Poisson case for short correlation lengths but a kind of regularization occurs for large correlation lengths, and the number variance approaches saturation values. These results are known in the study of integrable systems but are being demonstrated for the first time in random matrix theory. We conjecture that the interacting particle cases, which exhibit the characteristics of classical random matrices for short correlation lengths, will also show saturation effects for large correlation lengths.

description: Screen printed mono-crystalline Si solar cells yield efficiencies that are limited by electrical losses due to the front side
metallization process. Front side metallization of n-type and p-type Si solar cells with maximum efficiencies, p-type
18% and n-type 20 %, were analyzed with respect to their electrical properties and microstructure. In this work, the
electrical characterization together with a percolation model is presented, the microstructural results are presented in
an accompanying paper. To explain the current path, we introduced a percolation model, in which the Ag colloids
constitute current filaments in the glass layer with reduced resistance. The introduced percolation model is new and
different to the classical percolation model since it directly relies on the macroscopic resistance of such filaments. The
chemical analysis of the glass layer shows that it is semiconducting rather than insulating. Since the contact resistance
across the metallization is an important part of the series resistance of the solar cell, engineering of the glass layer
becomes essential for high-efficiency Si solar cells.
Mapping Uses, People and Places: Towards a Counter-Cartography of Commoning Practices and Spaces for Commons. A Case Study in Pavia, Italy

description: The agency of mapping has been an increasingly relevant area of enquiry in architecture, urbanism and landscape at the very least since James Corner published his seminal paper on the agency of mapping in 1999. A few projects aiming to map the commons in cities have since developed, providing critical or counter-cartographies in which information on local groups and communities, activities and other informal evidence is collated. This paper draws on the concept of urban commons as third places in the sense of being beyond market or state control and management, on the notion that commons cannot exist without commoning practices and on the idea of common spaces as distinct from public, private or communal ones. As such, urban commons should be mapped not as static or invariable but rather as dynamic entities that evolve over time. From that perspective, the agency of mapping should take into consideration both current commoning practices and places suitable for these agencies to happen. Spatial features and architectural configurations may also play a role in calling for, or hosting, those agencies. This paper proposes a methodology based on both primary and secondary data collection. The former is based on a variety of methods and tactics including psycho-geographical tours, non-interactive and interactive forms of observations and mapping. The process of mapping aims to showcase both what is already taking place and possibilities for future uses as a "hidden potential." The findings include the identification of specific places where several layers converge. These may become case studies that can be further investigated through methods such as research by design and community engagement.

description: In recent years epitaxially grown wafers (EpiWafers) made their way from small laboratory to
production scale fabrication. A lot of effort has been put into upscaling of tools, improvement of material quality and
in the fabrication of highly efficient solar cells. In this publication we investigate typical crystal defects appearing in
EpiWafer material and correlate them with process or reactor specific features like porous templates, thick epitaxial
layer growth or inline processing. We find two categories of stacking faults (SFs) which are either decorated with
inclusions or not. Besides particles on the surface of the growth template contaminations with oxygen are found to be
reasons for such polycrystalline inclusions. Stress leads to either delamination of the template or local lattice strain
both reasons for defect growth. Parallel faults which propagate along slipping lines in the material are interacting
with SFs although the correlation is not fully understood yet. Finally the recombination activity in SFs is found to be
especially high where the 111 planes meet or when strong decorating occurs. This work is a first step to
systematically investigate the crystallographic nature of EpiWafer material and will help to further improve processes
and equipment.

description: The public library holds a key position in the present geography of the urban public realm, as it emphasizes the centrality of self-directed culture in contemporary society by mirroring the processes of individual empowerment underpinned by technological changes. It transforms the public space in a place of collective action and individual participation, contributing to forming the urban commons in the contemporary splintered society. At present, visiting a library is an urban public act of collective participation / inclusion. The crucial condition for this is the paradigmatic transition from a passive knowledge-consumption model to an active knowledge-production model – by which libraries increasingly position ‘making’ at the intersection of public culture and public realm, bringing performative spaces and creative opportunities within the public sphere of all citizens. How do library buildings accommodate these public relationships, and in how far are they successful in doing it? The article proposes a theoretical underpinning framework for the development of the public library in the context of the contemporary socio-cultural conditions in order to position recent experiences in the Netherlands. The aim is to enlighten the current relationships between urban commons, making culture, and the architecture of the public library with an eye on future developments.

description: Light and elevated temperature induced degradation can be observed in multicrystalline Si PERC solar cells and results in efficiency losses of up to 12%rel. This work investigates the impact of temperature as well as doping on the degradation and regeneration behavior of lifetime samples. While ungettered Ga-doped samples did not show any regeneration effect within the duration of the experiment, increasing the treatment temperature sped up the degradation and regeneration where it could be observed. Ga-doped samples showed a slower degradation compared to B-doped samples. For higher temperatures (≥200°C) the lifetimes during regeneration exceeded the initial lifetimes before starting the illumination treatment for the gettered samples. After regeneration at higher temperature, the stability of lifetime at 75°C was tested. When tested after treatment at 150°C and before the lifetime exceeded the initial value, it stayed stable. After treatment at 250°C until the lifetime exceeded the initial lifetime, it decreased again during the stability test. However, the kinetics of this decrease was much slower than during the initial degradation.

description: The strain effect on electronic structure and thermoelectric properties of Higher Manganese Silicides (HMSs) Mn4Si7 was studied using Density Functional Theory (DFT) and through solving Boltzman Transport Equation (BTE). We found that the tensile strain attempts to reduce the band gap while the compressive strain not much affect to band gap. The Seebeck coeficient was found to be increased with increasing temperature, which is very consistent to experiments. The electrical conductivity and power factor show highly degree of anisotropy, where in-plane direction is more dominant. The different behavior of electrical conductivity along in-plane and outof plane direction was explained due to the change of band dispersion in the valence band maximum (VBM).
The New Role of Libraries: Places for All

description: Libraries are reinventing the concept of open public places for everyone by becoming third places. "Third places" is a term coined by sociologist Ray Oldenburg and refers to places where people spend time between home ("first" place) and work ("second" place). Famous coffee chains brand their stores as third places. But the most effective third places come from the community in many forms, from creative breeding grounds to cultural centres, from neighbourhood gardens to open public spaces and to libraries. Third places are playing a growing role in cities as they function as meeting places for a variety of people, as spaces for cooperation, connection and inspiration. The text presents three recently designed and built public library buildings---De Krook in Gent, Dokk1 in Aarhus and Oodi in Helsinki.

Robust leave-one-out cross-validation for high-dimensional Bayesian models

description: Leave-one-out cross-validation (LOO-CV) is a popular method for estimating out-of-sample predictive accuracy. However, computing LOO-CV criteria can be computationally expensive due to the need to fit the model multiple times. In the Bayesian context, importance sampling provides a possible solution but classical approaches can easily produce estimators whose asymptotic variance is infinite, making them potentially unreliable. Here we propose and analyze a novel mixture estimator to compute Bayesian LOO-CV criteria. Our method retains the simplicity and computational convenience of classical approaches, while guaranteeing finite asymptotic variance of the resulting estimators. Both theoretical and numerical results are provided to illustrate the improved robustness and efficiency. The computational benefits are particularly significant in high-dimensional problems, allowing to perform Bayesian LOO-CV for a broader range of models, and datasets with highly influential observations. The proposed methodology is easily implementable in standard probabilistic programming software and has a computational cost roughly equivalent to fitting the original model once.

description: We discuss a novel approach that allows to obtain effective potentials from ab initio trajectories. Our method consists in fitting the weighted radial distribution functions obtained from the ab initio data with the ones obtained from simulations with the effective potential, and using the parameters of the latter as fitting variables. As a case study, we consider the example of amorphous silica, a material that is highly relevant in the field of glass science as well as in geology. Our approach is able to obtain an effective potential that gives a better description with respect to structural and thermodynamic properties than the potential proposed by van Beest, Kramer, and van Santen, and that has been very frequently used as a model for amorphous silica. In parallel, we have also used the so-called "force matching" approach proposed by Ercolessi and Adams to obtain an effective potential. We demonstrate that for the case of silica this method does not yield a reliable potential and discuss the likely origin for this failure.

description: Background: Coronary heart disease (CHD) is one of the leading causes of death worldwide, and global mortality rates are expected to continue to rise over the coming decades. In Pakistan in particular, chronic diseases are responsible for 50% of the total disease burden. Circulating lipids are strongly and linearly associated with risk of CHD; however, despite considerable efforts to demonstrate causality, available evidence is conflicting and insufficient. Study of the underlying metabolic pathways implicated in the association between lipids and CHD would help to disentangle and elucidate these complex relationships. Objectives: The primary objectives of this dissertation were to (1) identify the genetic determinants of lipid metabolites and (2) advance understanding of the effect of perturbations in lipid metabolite levels on CHD and its risk factors. Methods: Direct infusion high-resolution mass spectrometry was performed on 5662 participants from the Pakistan Risk of Myocardial Infarction Study to obtain signals for 444 known lipid metabolites. Correlations and associations of the lipids with smoking, physical activity, circulating biomarkers, and other CHD risk factors were assessed. Genome-wide analyses were conducted to analyse the association of each lipid with over 6.7 million imputed single nucleotide polymorphisms. Functional annotation and Gaussian Graphical Modelling were used to link the variants associated with each lipid to the most likely mediating gene, discern the underlying metabolic pathways, and provide a visual representation of the genetic determinants of human metabolism. Mendelian randomisation was also implemented to examine the causal effect of lipids on risk of CHD. Results: The lipids were highly correlated with each other and with levels of major circulating lipids, and they exhibited significant associations with several CHD risk factors. There were 254 lipids that had significant associations with one or more genetic variants and 355 associations between lipids and variants, with a total of 89 sentinel variants from 23 independent loci. The analyses described in this dissertation resulted in the discovery of four novel loci, identified novel relationships between genetic variants and lipids, and revealed new biological insights into lipid metabolism. Conclusion: Analyses of lipid metabolites in large epidemiological studies can contribute to enhanced understanding of mechanisms for CHD development and identification of novel causal pathways and new therapeutic targets.
No-enclave percolation corresponds to holes in the cluster backbone

description: The no-enclave percolation (NEP) model introduced recently by Sheinman et al. can be mapped to a problem of holes within a standard percolation backbone, and numerical measurements of these holes gives the size-distribution exponent $τ= 1.82(1)$ of the NEP model. An argument is given that $τ=1 + d_B/2 \approx 1.822$ where $d_B$ is the backbone dimension. On the other hand, a model of simple holes within a percolation cluster implies $τ= 1 + d_f/2 = 187/96 \approx 1.948$, where $d_f$ is the fractal dimension of the cluster, and this value is consistent with Sheinman et al.'s experimental results of gel collapse which gives $τ= 1.91(6)$. Both models yield a discontinuous maximum hole size at $p_c$, signifying explosive percolation behavior. At $p_c$, the largest hole fills exactly half the system, due to symmetry. Extensive numerical simulations confirm our results.

description: Harmful and inaccurate narratives about the nature of mathematics, and about the mathematical incapability of historically marginalized groups, are pervasive and longstanding. The persistence of these narratives, and their documented negative impacts in school, the discipline, and beyond, have led some scholars to conclude that there is something about mathematics itself, and the way that it has been enacted in schools, that upholds and reproduces these narratives – even suggesting that ideologies of oppression, such as whiteness or antiblackness, are intertwined with mathematics. Despite the strength of this criticism, the idea that proof might be implicated in this reproduction of harm has remained largely unexplored. Through an analysis of my own practice in a course for pre-service secondary teachers on mathematical proof, this dissertation investigates and unpacks proof’s role in the reification of these harmful narratives and asks whether it is possible for proof (as it exists in teaching and learning in schools) to be different. At the same time, it also considers what it might take for teachers to disrupt this reification. Specifically, this conceptual-analytic first-person research project considers data drawn from the design and enactment of proof-focused tasks to investigate the following questions: What might a conceptualization of proof that is simultaneously grounded in the discipline, useful for teaching, and aimed at disrupting longstanding and pervasive harms look like – what might be its character, and how might such a conceptualization shape the mathematical interactions between teacher and students? What might teaching that is oriented to conceptualizing proof in this way entail? My analysis thus tests and refines possible alternative conceptualizations of proof, grapples with the integrity and coherence of such conceptualizations, and identifies challenges for teaching with them in mind. In addition to demonstrating how a conceptualization of proof might carry and uphold potentially harmful ideological commitments, I argue that alternative conceptualizations of proof can make possible more humanizing ways of interacting mathematically, while still being useful for teaching, and maintaining disciplinary integrity. In particular, I identify affordances and constraints of a conceptualization of proof that is principally concerned with the sharing of insight and building consensus – ultimately concluding that such a conceptualization seemed to support more informal and idiosyncratic contributions from students as well as encourage more asset-oriented interactions where the collective seemed to value and invest in student insights on their own terms.

description: Boron-doped Czochralski-grown silicon (Cz-Si), as used in the industrial production of solar cells today,
is suffering from a light-induced degradation (LID) of the carrier lifetime during illumination. It has been known since
a decade that under lab conditions, this degradation can be permanently cured by illumination at increased temperature,
which has been known as ‘regeneration’ treatment. In this contribution, we examine the permanent regeneration of the
carrier lifetime in standard boron-doped Cz-Si using an industrial combined fast-firing and regeneration furnace - the
c.FIRE REG of centrotherm photovoltaics. Our study reveals that for an optimized firing and regeneration process,
very high implied open-circuit voltages Voc.impl exceeding 740 mV are achieved on standard 1-2 cm p-type Cz-Si
wafers. These very high measured Voc.impl values clearly indicate the suitability of the process for highly efficient PERC
cell production. Additionally, as the c.FIRE REG furnace is realized in a belt-line configuration, which exposes each
wafer for less than 70 s to the firing and regeneration conditions, our experiments clearly demonstrate the excellent
suitability of the examined tool for the implementation into industrial solar cell production lines. We also demonstrate
the successful application to industrial PERC solar cells produced by two different manufacturers.
The Shape of Life: Reading Space in Sai Paranjpye's Cinema (1980-2009)
Creators: name: Bakshi, Swati
Publisher: name: University of Westminster
Year: 2023

description: This thesis is an interdisciplinary spatial exploration of the films of Indian director Sai Paranjpye. The thesis examines the aesthetic and narrative strategies of spatial representation in seven of Paranjpye’s films – Sparsh (1980), Chashme Baddor (1981), Katha (1982), Disha (1990), Papeeha (1993), Choodiyan (1993) and Suee (2009). Employing a mixed methodology drawn from the disciplines of human geography, urban studies, sociology, feminist theory and gender studies in reading spaces, I suggest that Paranjpye depicts fragmented Indian life at the intersection of the spatial and the social in this body of films. This encounter of spatial and social is crucial in structuring the ideas of identity, inter-personal relationships and the experience of modernity. Through a textual analysis of each film, the thesis argues that it is essentially the lived space and architectural form that structures life and manifests lived experience in this selected body of films. The thesis identifies five major themes – border crossing, perceptions of home, marginality, private/public divisions and the potential of Mazaa (fun) – that bind together these lived filmic geographies and determine the texture of life. The thesis contextualises Paranjpye’s body of work in relation to the medial environment of the 1970s-80s. It also traces the influence of the cinematic forms of middle cinema and India’s new wave film movement on Paranjpye’s cinema to discover continuities, discontinuities and the subversive potential of these films. In this regard, I argue that Paranjpye’s cinema disrupts the genre orthodoxies that regard middle cinema as middle ‘class’ cinema. This exploration reveals that these films are in constant dialogue with various visual forms that evolved during the 1970s-80s and that they revel in aesthetic fluidity, challenging the strict generic borders.

description: Individuals with South Asian ancestry have a higher risk of heart disease than other groups but have been largely excluded from genetic research. Using data from 22,000 British Pakistani and Bangladeshi individuals with linked electronic health records from the Genes & Health cohort, we conducted genome-wide association studies of coronary artery disease and its key risk factors. Using power-adjusted transferability ratios, we found evidence for transferability for the majority of cardiometabolic loci powered to replicate. The performance of polygenic scores was high for lipids and blood pressure, but lower for BMI and coronary artery disease. Adding a polygenic score for coronary artery disease to clinical risk factors showed significant improvement in reclassification. In Mendelian randomisation using transferable loci as instruments, our findings were consistent with results in European-ancestry individuals. Taken together, trait-specific transferability of trait loci between populations is an important consideration with implications for risk prediction and causal inference.

description: Multicrystalline silicon (mc-Si) is the workhorse of photovoltaics with a market share above 60%,
being acidic textured (isotextured) silicon the standard. For optical simulations, the spherical caps model is widely
applied, but it was reported that is does not correctly describe the angular dependence of reflection. In this work, our
first objective is to verify this. Secondly, we want to obtain an improved model for optics of isotextured mc-Si wafers
and solar cells able to describe the light trapping properties of cells and modules correctly. We investigate the
reflectance of isotextured silicon by varying the angle of incidence of the light between 8° and 80°. We perform
measurements of nine isotextured samples, obtaining reflectance curves with a similar shape, but they differ by up to
60%abs from previously published data. The first simulations are performed using the spherical caps model, which is
shown to be inaccurate to describe the angle-dependent reflectance of isotextured silicon. In the second set of
simulations we vary the texture morphology, reducing the deviations of the simulation from the measurement from
8% to 1.2% for incident angles smaller than 60°. We conclude that alternative morphologies are worth doing further
research.

description: Imaging companions to main-sequence stars often allows to detect a projected orbital motion. MCMC has become very popular in for fitting their orbits. Some of these companions appear to move on very eccentric, possibly unbound orbits. This is the case for the exoplanet Fomalhaut b and the brown dwarf companion PZ Tel B. For such orbits, standard MCMC codes assuming only bound orbits may be inappropriate. We develop a new MCMC implementation able to handle bound and unbound orbits as well in a continuous manner, and we apply it to the cases of Fomalhaut b and PZ Tel B. This code is based on universal Keplerian variables and Stumpff functions formalism. We present two versions of this code, the second one using a different set of angular variables designed to avoid degeneracies arising when the projected orbital motion is quasi-radial, as it is the case for PZ Tel B. We also present additional observations of PZ Tel B. The code is applied to Fomalhaut b and PZ Tel B. Concerning Fomalhaut b, we confirm previous results, but we show that open orbital solutions are also possible. The eccentricity distribution nevertheless peaks around ~0.9 in the bound regime. We present a first successful orbital fit of PZ Tel B, showing in particular that the eccentricity distribution presents a sharp peak very close to e=1, meaning a quasi-parabolic orbit. It was recently suggested that unseen inner companions may lead orbital fitting algorithms to artificially give high eccentricities. We show that this caveat is unlikely to apply to Fomalhaut b. Concerning PZ Tel B, an inner ~12 MJup companion would mimic a e=1 orbit despite a real eccentricity around 0.7, but a dynamical analysis reveals that such a system would not be stable. We conclude that our orbital fit is robust.

description: The capability to adapt compliance by varying muscle stiffness is crucial for dexterous manipulation skills in humans. Incorporating compliance in robot motor control is crucial to performing real-world force interaction tasks with human-level dexterity. This work presents a Deep Model Predictive Variable Impedance Controller for compliant robotic manipulation which combines Variable Impedance Control with Model Predictive Control (MPC). A generalized Cartesian impedance model of a robot manipulator is learned using an exploration strategy maximizing the information gain. This model is used within an MPC framework to adapt the impedance parameters of a low-level variable impedance controller to achieve the desired compliance behavior for different manipulation tasks without any retraining or finetuning. The deep Model Predictive Variable Impedance Control approach is evaluated using a Franka Emika Panda robotic manipulator operating on different manipulation tasks in simulations and real experiments. The proposed approach was compared with model-free and model-based reinforcement approaches in variable impedance control for transferability between tasks and performance.

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 212-217
description: This paper describes a n & p surface Ni/Ag co-plating process for the metallization of bifacial cells
suitable for multi-wire module integration. The process, based on electroless Ni and immersion Ag plating, mitigates
typical problems of achieving simultaneous electroless Ni plating onto n & p surfaces by the use of a novel silicon
selective activation step. Key attractive features of this metallization process include low cost from low Ag usage
(typically < 8 mg/cell) and low stress batch processing with no cell contacting using low Capex high throughput tools.
The plating process is applied to metallize bifacial nPERT+ cells achieving average cell efficiencies of 22.4% with
typical cell bifacialities above 95%. Limited 1 cell laminate reliability data is given with IEC61215 thermal cycling
and damp heat test criteria being met. Finally we present cost-of-ownership estimates at the cell level ($/cell), module
level ($/Wp) and system level LCOE ($/kWh) for multi-wire modules made from nPERT+ cells using the co-plating
process and compare the results to conventional modules with screen printed pPERC+ cells. Reductions in the LCOE
of ≥ 5% are estimated for co-plated nPERT+ cell multi-wire modules for albedo values ≥10%.

description: Applying the Fermi-Bose equivalence and the boundary state formulation, we study the hetero-junction of two quantum wires. Two quantum wires are described by Tomonaga-Luttinger (TL) liquids with different TL parameters and electrons transport between two wires is depicted by a simple hopping interaction. We calculate the radiative corrections to the hopping interaction and obtain the renormalization (RG) exponent, making use of the perturbation theory based on the boundary state formulation. The model exhibits a phase transition at zero temperature. We discuss the critical line which defines the phase boundary on the two dimensional parameter space. The model also exhibits the particle-kink duality, which maps the strong coupling regime of the model onto the weak coupling regime of the dual model. The strong coupling regime of the model is found to match exactly the weak coupling regime of the dual model. This model is also important to study the critical behaviors of the two dimensional dissipative system with anisotropic friction coefficients.

Protein Binding Affinity Prediction

description: The representation of the protein-ligand complexes used in building machine learning models play an important role in the accuracy of binding affinity prediction. The Extended Connectivity Interaction Features (ECIF) is one such representation. We report that (i) including the discretized distances between protein-ligand atom pairs in the ECIF scheme improves predictive accuracy, and (ii) in an evaluation using gradient boosted trees, we found that the resampling method used in selecting the best hyperparameters has a strong effect on predictive performance, especially for benchmarking purposes.
