description: The Markov Chain Monte Carlo method is at the heart of efficient approximation schemes for a wide range of problems in combinatorial enumeration and statistical physics. It is therefore very natural and important to determine whether quantum computers can speed-up classical mixing processes based on Markov chains. To this end, we present a new quantum algorithm, making it possible to prepare a quantum sample, i.e., a coherent version of the stationary distribution of a reversible Markov chain. Our algorithm has a significantly better running time than that of a previous algorithm based on adiabatic state generation. We also show that our methods provide a speed-up over a recently proposed method for obtaining ground states of (classical) Hamiltonians.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 973-976
description: In this work Pillar Ltd presents the results of development of technology for growing mono-like crystalline silicon ingots for photovoltaic application, which has a number of advantages resulting in a relatively low production cost and high material quality. Experimental mono-like silicon ingots and wafers were produced. Electrophysical properties of produced material were investigated. The parameters of mono-like ingots were
compared with those of multicrystalline silicon ingots produced at Pillar Ltd using traditional technology of directional solidification. Mono-like ingots gain a number of advantages over directionally solidified ingots: more homogeneous crystalline structure and higher minority carrier lifetime. Mono-like ingot slicing made at Pillar resulted in high-quality wafers with significantly big crystalline grains of <100> orientation. Solar cells and modules were produced of wafers from mono-like crystalline ingot with application of high effective alkaline texturing. Cell efficiency and module power distributions are reported. Obtained values are approaching the ones for monocrystalline cells and modules. Presented results confirm the promising use of mono-like technology for solar cells application.

description: The greybody factor of the massive Dirac field around the black hole in the dRGT massive gravity theory is investigated using the rigorous bound and the WKB approximation methods. In both methods, the greybody factor significantly depends on the shape of the potential. If the potential is smaller, there is more probability for the Dirac field to transmit through the black hole, therefore, the greybody factor is higher. Moreover, there exists a critical mass of the Dirac field such that the greybody factor is maximum. By comparing the results from these two methods, we argue that it is useful to use the rigorous bound method for the low potential cases, while using the WKB approximation method for the high potential cases.

Silicon Solar Cell Characterization and Modelling

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1262-1264
description: We have investigated the potential to accelerate three-dimensional numeric simulation of silicon solar
cell using thread parallelism. The device simulated is a rear side passivated cell with rear point contacts (PERC). The
optical and electrical behaviour of the device was simulated with Sentaurus Device (formerly dessis). We show that
the simulation run-time on a four socket Opteron 6168 machine is reduced down to 24% compared to the run-time on
quad-core machine. Furthermore, limits of time reduction by varying the number of threads up to 48 are studied.
Thereby, the number of threads for the optimum use of the hardware resources is determined.

description: We have studied the structural, magnetic and electronic properties of Co-implanted ZnO (0001) films grown on Al2O3 (1120) substrates for different implantation doses and over a wide temperature range. Strong room temperature ferromagnetism is observed with magnetic parameters depending on the cobalt implantation dose. A detailed analysis of the structural and magnetic properties indicates that there are two magnetic phases in Co-implanted ZnO films. One is a ferromagnetic phase due to the formation of long range ferromagnetic ordering between implanted magnetic cobalt ions in the ZnO layer, the second one is a superparamagnetic phase, which occurs due to the formation of metallic cobalt clusters in the Al2O3 substrate. Using x-ray resonant magnetic scattering, the element specific magnetization of cobalt, oxygen and Zn was investigated. Magnetic dichroism was observed at the Co L2,3 edges as well as at the O K edge. In addition, the anomalous Hall effect is also observed, supporting the intrinsic nature of ferromagnetism in Co-implanted ZnO films.

description: The influence of various design parameters on the performance of rear point contact solar cells
with selective emitter structure with cell thickness of 100 μm has been investigated using three-dimensional (3D)
numerical simulations. The results predict a drop of 0.6 mA/cm² in Jsc if the thickness is reduced from 180 μm to
100 μm with the same design parameters. As a consequence, the efficiency drops by 0.2 % absolute. To
compensate for this efficiency loss the potential for improvements are studied by ranging the following three
parameters: the surface recombination velocity (Srear) of rear side interface between silicon and aluminum, the
Shockley-Read-Hall (SRH) lifetime in bulk (SRH) and the contact resistivity (rear) for rear contacts. Among them,
Srear is the most important parameter to recover the losses induced by using 100 μm thick wafer in industrial
production.

description: Smart solar support schemes are essential to market growth, yet their design is all too often a product
of political winds, status quo inertia, and happenstance, while a structured approach for evaluating the options is
frequently lacking. This paper begins by identifying energy system needs and the criteria for a successful support
scheme at various market phases, from inception through to mainstream and beyond. It then presents an analysis of
the effectiveness of common solar photovoltaic incentives in fulfilling these changing needs. Looking to the future,
this paper examines each incentive's strengths and weaknesses after achievement of grid parity and mainstream
status. Finally, utilizing Germany as a case study, it proposes alternative and supplementary support mechanisms to
continue to support the deployment of solar photovoltaics as broader system issues such as grid integration and
market design become increasingly important.

description: Many platforms for benchmarking optimization algorithms offer users the possibility of sharing their experimental data with the purpose of promoting reproducible and reusable research. However, different platforms use different data models and formats, which drastically inhibits identification of relevant data sets, their interpretation, and their interoperability. Consequently, a semantically rich, ontology-based, machine-readable data model is highly desired. We report in this paper on the development of such an ontology, which we name OPTION (OPTImization algorithm benchmarking ONtology). Our ontology provides the vocabulary needed for semantic annotation of the core entities involved in the benchmarking process, such as algorithms, problems, and evaluation measures. It also provides means for automated data integration, improved interoperability, powerful querying capabilities and reasoning, thereby enriching the value of the benchmark data. We demonstrate the utility of OPTION by annotating and querying a corpus of benchmark performance data from the BBOB workshop data - a use case which can be easily extended to cover other benchmarking data collections.

description: We investigate the mechanical response of jammed packings of circulo-lines, interacting via purely repulsive, linear spring forces, as a function of pressure $P$ during athermal, quasistatic isotropic compression. Prior work has shown that the ensemble-averaged shear modulus for jammed disk packings scales as a power-law, $\langle G(P) \rangle \sim P^β$, with $β\sim 0.5$, over a wide range of pressure. For packings of circulo-lines, we also find robust power-law scaling of $\langle G(P)\rangle$ over the same range of pressure for aspect ratios ${\cal R} \gtrsim 1.2$. However, the power-law scaling exponent $β\sim 0.8$-$0.9$ is much larger than that for jammed disk packings. To understand the origin of this behavior, we decompose $\langle G\rangle$ into separate contributions from geometrical families, $G_f$, and from changes in the interparticle contact network, $G_r$, such that $\langle G \rangle = \langle G_f\rangle + \langle G_r \rangle$. We show that the shear modulus for low-pressure geometrical families for jammed packings of circulo-lines can both increase {\it and} decrease with pressure, whereas the shear modulus for low-pressure geometrical families for jammed disk packings only decreases with pressure. For this reason, the geometrical family contribution $\langle G_f \rangle$ is much larger for jammed packings of circulo-lines than for jammed disk packings at finite pressure, causing the increase in the power-law scaling exponent.

description: Based on the outdoor test PV power plant near Zürich the inverter performance under field conditions
has been analysed and compared to manufacturer data. Tracking and conversion efficiency is treated separately.
Tracking performance depends on the generator’s Maximum-Power-Point, which cannot be measured while the
inverter’s tracking is in operation. The generator’s maximum output power is therefore deduced from a reference
module. Tracking performance above 98% could be determined under stable environmental conditions, defined by
low fluctuating irradiance and module temperature. Comparing conversion performance under the same steady
conditions to the hEURO generally showed lower measured efficiency as expected by the datasheet. By recalculating
the weighting factors used for the calculation of hEURO, site and system specific conversion performance expectancies
(hEURO adapted) have been determined to differ only by 0.3% to hEURO. Direct comparison between measured and,
according to the datasheet, expected conversion performance for different output power levels of the inverter have
shown very different conversion characteristics under field than under laboratory conditions leading to losses of over
2% under steady conditions without considering measurement uncertainty of 1.1% (k=2).

description: We report observations of thermal emission from the frontal structure of a coronal mass ejection (CME) using data obtained with the Gauribidanur RAdioheliograPH (GRAPH) simultaneously at 80 MHz and 53 MHz on 2016 May 1. The CME was due to activity on the far-side of the Sun, but near its limb. No non-thermal radio burst activity were noticed. This provided an opportunity to observe the faint thermal radio emission from the CME, and hence directly estimate the electron density, mass, and magnetic field strength of the plasma entrained in the CME. Considering that CMEs are mostly observed only in whitelight and reports on their plasma characteristics are also limited, the rare direct radio observations of thermal emission from a CME and independent diagnosis of its plasma parameters are important measurements in the field of CME physics.

description: Coulomb excitation is a standard method used to extract quadrupole excitation strengths of even-even nuclei. In typical analyses the reaction is assumed to be one-step, Coulomb only, and is treated within a semi-classical model. In this work, fully-quantal coupled-channel calculations are performed for three test cases in order to determine the importance of multi-step effects, nuclear contributions, feeding from other states and corrections to the semi-classical approximation. We study the excitation of 30S, 58Ni and 78Kr on 197Au at ~ 50 AMeV. We find that nuclear effects may contribute more than 10% and that feeding contributions can be larger than 15%. These corrections do not alter significantly the published B(E2) values, however an additional theoretical error of up to 13% should be added to the experimental uncertainty if the semi-classical model is used. This theoretical error is reduced to less than 7% when performing a quantal coupled-channel analysis.

description: We study the appearance of anomalies of the Master Ward Identity, which is a universal renormalization condition in perturbative QFT. The main insight of the present paper is that any violation of the Master Ward Identity can be expressed as a LOCAL interacting field; this is a version of the well-known Quantum Action Principle of Lowenstein and Lam. Proceeding in a proper field formalism by induction on the order in $\hbar$, this knowledge about the structure of possible anomalies as well as techniques of algebraic renormalization are used to remove possible anomalies by finite renormalizations. As an example the method is applied to prove the Ward identities of the O(N) scalar field model.

description: We analyze the projected effective Einstein equation in a 4-dimensional arbitrary manifold embedded in a 5-dimensional Riemann-Cartan manifold. The Israel-Darmois matching conditions are investigated, in the context where the torsion discontinuity is orthogonal to the brane. Unexpectedly, the presence of torsion terms in the connection does not modify such conditions whatsoever, despite of the modification in the extrinsic curvature and in the connection. Then, by imposing the Z_2-symmetry, the Einstein equation obtained via Gauss-Codazzi formalism is extended, in order to now encompass the torsion terms. We also show that the factors involving contorsion change drastically the effective Einstein equation on the brane, as well as the effective cosmological constant.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 3177-3181
description: The photovoltaic (PV) industry’s biggest challenge ahead is the cost reduction per Watt for PV
modules. Among other economic aspects the control of the cell technology in PV modules is surely one of the key
components to meet this challenge. Sorting of cells in different classes is indispensable to manufacture optimized
modules. Prior methods and studies concentrate on sorting with respect to electrical parameters only, thus
categorizing the cells in current, voltage and power classes. This study extends the sorting concept with simulations
including optical parameters and combinations with electrical parameters. Different module configurations arising
from interconnection of the cells from the sorted classes to a module are simulated using LTSPICE and MATLAB to
predict optimum module performance. It is shown that the newly introduced sorting parameters allow industrial
manufacturers to enhance module efficiencies for low light levels and also the yearly yield can be improved by 0.12%
compared to conventional sorting methods.
Statistical modelling of sediment concentration
Creators: name: Thompson, Mai Phuong
Publisher: name: University of British Columbia
Year: 2010

description: One technique that is commonly used to replace the costly daily sampling of sedimentconcentration in assessing sediment discharge is the "rating curve" technique. This technique relies on the form of the relationship between sediment concentration and water discharge to estimate long-term sediment loads. In this study, a regression/time-series approach to modelling the relationship between sediment concentration and water discharge is developed. The model comprises of a linear regression of the natural logarithm of sediment concentration on the natural logarithm of water discharge and an autoregressive time-series of order one or two for the errors of the regression equation. The main inferences from the model are the estimation of annual sediment loads and the calculation of their standard errors. Bias correction factors for the bias resulted from the inverse transformation of the natural logarithm of sediment concentration are studied. The accuracy of the load estimates is checked by comparing them to figures published by Water Survey of Canada.

description: Masting characterizes large, intermittent and highly synchronous seeding events among individual plants and is found throughout the plant Tree of Life (ToL). Although masting can increase plant fitness, little is known about whether it results in evolutionary changes across entire clades, such as by promoting speciation or enhanced trait selection. Here, we tested if masting has macroevolutionary consequences by combining the largest existing dataset of population-level reproductive time series and time-calibrated phylogenetic tree of vascular plants. We found that the coefficient of variation (CVp) of reproductive output for 307 species covaried with evolutionary history, and more so within clades than expected by random. Speciation rates estimated at the species level were highest at intermediate values of CVp and regional-scale synchrony (Sr) in seed production, that is, there were unimodal correlations. There was no support for monotonic correlations between either CVp or Sr and rates of speciation or seed size evolution. These results were robust to different sampling decisions, and we found little bias in our dataset compared with the wider plant ToL. While masting is often adaptive and encompasses a rich diversity of reproductive behaviours, we suggest it may have few consequences beyond the species level. This article is part of the theme issue 'The ecology and evolution of synchronized seed production in plants'.

description: To explore the clinicopathologic and prognostic significance of circular RNA plasmacytoma variant translocation 1 (circPVT1) in various cancers. Several databases were searched for eligible studies published before March 01, 2021. The pooled odds ratios (ORs) with 95% confidence interval (95% CI) were calculated to assess the association between circPVT1 expression and prognostic outcomes of tumor including age, gender, clinical stage, tumor size, metastasis and overall survival. Begg’s funnel plots and Egger’s test were used to evaluate the publication bias. The robustness of our results was assessed using sensitivity analysis. Ten studies comprising a total of 878 patients with cancer were included in this meta-analysis. The results showed that the high expression of circPVT1 was significantly related to clinical stage (OR=3.44, 95% CI: 2.40-4.94, P<0.05), tumor size (OR=2.29, 95% CI: 1.38-3.79, P<0.05), metastasis (OR=2.97, 95% CI: 2.06-4.28, p<0.05) and overall survival of cancer (OR=3.30, 95% CI: 2.26-4.84, p<0.05), but not associated with age and gender of patients with tumor. No publication bias was found. High expression of circPVT1 may predict an advanced clinical stage and poor prognosis of tumor, suggesting that circPVT1 may serve as a potential prognostic marker in cancers.

description: A method is developed to calculate the ligand field (LF) parameters and the multiplet spectra of local magnetic centers with open $d$- and $f$-shells in solids in a parameter-free way. This method proceeds from density functional theory and employs Wannier projections of nonmagnetic band structures onto local $d$- or $f$-orbitals. Energies of multiplets and optical, as well as X-ray spectra are determined by exact numerical diagonalization of a local Hamiltonian describing Coulomb, LF, and spin-orbit interactions. The method is tested for several 3$d$- and 5$f$-compounds for which the LF parameters and multiplet spectra are experimentally well known. In this way, we obtain good agreement with experiment for La$_2$NiO$_4$, CaCuO$_2$, Li$_2$CuO$_2$, ZnO:Co, and UO$_2$.

description: The Atiyah-Singer index theorem is generalized to a two-dimensional SO(3) Yang-Mills-Higgs (YMH) system. The generalized theorem is proven by using the heat kernel method and a nonlinear realization of SU(2) gauge symmetry. This theorem is applied to the problem of deriving a charge quantization condition in the four-dimensional SO(3) YMH system with non-Abelian monopoles. The resulting quantization condition, eg=n (n: integer), for an electric charge e and a magnetic charge g is consistent with that found by Arafune, Freund and Goebel. It is shown that the integer n is half of the index of a Dirac operator.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1268-1271
description: A novel loss term is introduced into the standard equivalent circuit of heterojunction cells, which represents
bulk recombination losses. This loss term is modelled as a kind of photoconductor which is an additional shunt
loss for the device.
Experimental evidence comes from data obtained by Variable Illumination measurements (VIM), where the
short circuit resistance Rsc=(V/I)V=0, is presented as a function of logarithmically varying illumination levels.
It is only at lowest illumination, that Rsc is determined by leakage currents. At standard illumination levels
around one sun, Rsc is determined by the novel bulk recombination term. A confirmation of the nature of the
novel loss term comes from numerical device simulations done under SILVACO.
The experimental VIM-data come from a novel experimental set-up which is using LEDs for the variation of
the illumination level.

description: We prove that the jacobian of a hyperelliptic curve $y^2=(x-t)h(x)$ has no nontrivial endomorphisms over an algebraic closure of the ground field $K$ of characteristic zero if $t \in K$ and the Galois group of the polynomial $h(x)$ over $K$ is "very big" and $deg(h)$ is an even number >8. (The case of odd $deg(h)>3$ follows easily from previous results of the author.)

description: This paper is mainly focusing on electrochemical failure modes for silicon based technology frequently
observed in field recently and referred to as so-called ‘snail tracks’. Suitable test sequences are presented for both
failure provoking and for risk analysis for field panels already affected. Different field findings - referred to as ‘snail
tracks’ - have been categorized with respect to their optical appearance. Relevance for power and yield issues in field
has been investigated and correlated to underlying crack issue as well as additional corrosive phenomena. Affected
field panels have been further characterized with respect to their isolation properties. Results for leakage current
measurements as well as interfacial adhesion (glass/EVA) are presented. Material investigations have been conducted
and bulk resistivity for different encapsulation materials (including different EVA types/suppliers) are presented.
Afterword: Citizenship and the politics of (im)material stigma and infrastructure
Creators: name: Lemanski, Charlotte
Publisher: name: Apollo - University of Cambridge Repository
Year: 2021

description: This afterword to the Urban Vulnerabilities: Infrastructure, Health and Stigma special issue highlights two cross-cutting themes that are addressed by all the articles in the issue, and that have the potential to make a significant contribution to debates within urban studies. First, I reflect on how the articles reveal the inseparable connections between infrastructure and stigma, demonstrating both as political and material processes that are inter-dependent and mutually constitutive. Consequently, it is urgent to bridge disciplinary siloes in bringing these scholarly debates into deeper conversation in ways that recognise the materiality of stigma and the politicisation of infrastructure (and vice versa). Second, to a greater and lesser extent, the articles all reveal the centrality of citizenship to the capacity of both urban dwellers and the state to negotiate and/or restrict access to infrastructure, and to perpetuate and/or challenge the impacts of stigma. While the connections between infrastructure and citizenship are explored in my recent work on infrastructural citizenship, the articles in this collection demonstrate the importance of temporality and scale in understanding how citizens negotiate their material and political rights.
Comment on "Flavor invariants and renormalization-group equations in the leptonic sector with massive Majorana neutrinos"

description: Recently in [JHEP 09 (2021) 053], Wang et al. discussed the polynomial ring formed by flavor invariants in the leptonic sector with massive Majorana neutrinos. They have explicitly constructed the finite generating sets of the polynomial rings for both two-generation scenario and three-generation scenario. However, Wang et al.'s claim of the finiteness of the generating sets of the polynomial rings and their calculation by the approach of Hilbert series with generalized Molien-Weyl formula are both based on their assertion that the unitary group ${\rm U}(n,\mathbb{C})$ is reductive, which is unfortunately incorrect. The property of being reductive is only applicable to linear algebraic groups. And it is well-known that the unitary group ${\rm U}(n,\mathbb{C})$ is not even a linear algebraic group. In this paper, we point out the above issue and provide a solution to fill in the accompanying logical gaps in [JHEP 09 (2021) 053]. Some important results from the theory of linear algebraic group, the invariant theory of square matrices and group theory are needed in the analysis. We also clarify some somewhat misleading or vague statements in [JHEP 09 (2021) 053] about the scope of flavor invariants. Note that, although built from incorrect assertion, Wang et al.'s calculation results in [JHEP 09 (2021) 053] are nonetheless correct, which is ultimately because the ring of invariants of ${\rm U}(n,\mathbb{C})$ is isomorphic to that of ${\rm GL}(n,\mathbb{C})$ which is itself reductive.

description: A continuous time cluster algorithm for two-level systems coupled to a dissipative bosonic bath is presented and applied to the sub-ohmic spin-Boson model. When the power s of the spectral function J(w) \propto w^s is smaller than 1/2, the critical exponents are found to be classical, mean-field like. Potential sources for the discrepancy with recent renormalization group predictions are traced back to the effect of a dangerously irrelevant variable.

description: Serotonin is involved in updating responses to changing environmental circumstances. Optimising behaviour to maximise reward and minimise punishment may require shifting strategies upon encountering new situations. Likewise, autonomic responses to threats are critical for survival yet must be modified as danger shifts from one source to another. Whilst numerous psychiatric disorders are characterised by behavioural and autonomic inflexibility, few studies have examined the contribution of serotonin in humans. We modelled both processes, respectively, in two independent experiments (N = 97). Experiment 1 assessed instrumental (stimulus-response-outcome) reversal learning whereby individuals learned through trial and error which action was most optimal for obtaining reward or avoiding punishment initially, and the contingencies subsequently reversed serially. Experiment 2 examined Pavlovian (stimulus-outcome) reversal learning assessed by the skin conductance response: one innately threatening stimulus predicted receipt of an uncomfortable electric shock and another did not; these contingencies swapped in a reversal phase. Upon depleting the serotonin precursor tryptophan-in a double-blind randomised placebo-controlled design-healthy volunteers showed impairments in updating both actions and autonomic responses to reflect changing contingencies. Reversal deficits in each domain, furthermore, were correlated with the extent of tryptophan depletion. Initial Pavlovian conditioning, moreover, which involved innately threatening stimuli, was potentiated by depletion. These results translate findings in experimental animals to humans and have implications for the neurochemical basis of cognitive inflexibility.

description: We analyze the periodically forced Kuramoto model. This system consists of an infinite population of phase oscillators with random intrinsic frequencies, global sinusoidal coupling, and external sinusoidal forcing. It represents an idealization of many phenomena in physics, chemistry and biology in which mutual synchronization competes with forced synchronization. In other words, the oscillators in the population try to synchronize with one another while also trying to lock onto an external drive. Previous work on the forced Kuramoto model uncovered two main types of attractors, called forced entrainment and mutual entrainment, but the details of the bifurcations between them were unclear. Here we present a complete bifurcation analysis of the model for a special case in which the infinite-dimensional dynamics collapse to a two-dimensional system. Exact results are obtained for the locations of Hopf, saddle-node, and Takens-Bogdanov bifurcations. The resulting stability diagram bears a striking resemblance to that for the weakly nonlinear forced van der Pol oscillator.

description: It is well known that photovoltaic efficiency is strongly temperature dependent. As the temperature
raises, the internal resistance of the material increases and the electrical conductivity decreases. This can be a major
problem in building-integrated photovoltaic (PV) devices where free convection cooling is limited, especially during
summer in hot climate such as in South Greece. Various existing techniques to lower PV panels’ temperature are
initially presented in this paper. In this study focuses on the combination of a photovoltaic panel with a Phase Change
Material (PCM) in order to reduce the daily temperature of the PV panel and improve the overall efficiency of the
system. The experimental concept of integrating PCM on the PV panels located in the laboratory of Renewable and
Sustainable Energy Systems, Technical University of Crete, Chania is presented. In Mediterranean climates there are
very limited results of the behaviour of amorphous and microcrystalline silicon thin film solar cells modules when
combined with PCMs.
