description: We study the decay Omega^- -> Xi^- pi^+ pi^- in heavy-baryon chiral perturbation theory. At leading order, the decay is completely dominated by the Xi^{*0}(1530) intermediate state, and the predicted rate and Xi^-pi^+ mass distribution are in conflict with currently available data. It is possible to resolve this conflict by considering additional contributions at next-to-leading order.

description: Linear Kinematic Features (LKFs) are found everywhere in the Arctic sea ice cover. They are strongly localized deformations often associated with the formation of leads and pressure ridges. Viscous-plastic sea ice models start to generate LKFs at high spatial grid resolution, typically with a grid spacing below 5 km. Besides grid spacing, other aspects of a numerical implementation, such as discretization details, may affect the number and definition of simulated LKFs. To explore these effects, the solutions of sea ice models with different grid spacings, mesh types, and numerical discretization techniques are compared in an idealized configuration, which could also serve as a benchmark problem in the future. The A, B, and C-grid discretizations of sea ice dynamics on quadrilateral meshes leads to a similar number of LKFs as the A-grid approximation on triangular meshes (with the same number of vertices). The discretization on an Arakawa CD-grid on both structured quadrilateral and triangular meshes resolves the same number of LKFs as conventional Arakawa A-grid, B-grid, and C-grid approaches, but on two times coarser meshes. This is due to the fact that the CD-grid approach has a higher number of degrees of freedom to discretize the velocity field. Due to its enhanced resolving properties, the CD-grid discretization is an attractive alternative to conventional discretizations.

description: High energy photons can be generated via inverse Compton scattering (ICS) in the collision between energetic electrons and intense laser pulse. The development of laser plasma accelerators promises compact and all-optical gamma-ray sources by colliding the electrons from laser wakefield accelerators to its high-power driving pulse reflected by a plasma mirror. However, the law of optical focusing hinders realization of both high photon yield and monochromatic spectrum in this scenario. We propose an azimuthal spatial-temporal convertor that decouples the focal field strength from laser spot size using helical parabolic geometry. It decomposes the driving laser beam into a pulse train of almost identical divergence angle and focal depth, creating synchronized ICS in the optimized linear regime. The scheme resolves the dilemma between high efficiency and narrow energy spread, facilitating the generation of monochromatic gamma-ray using high power lasers beyond relativistic field strengths.

description: This research is concerned with the novel application and investigation of `Soft Actor Critic' (SAC) based Deep Reinforcement Learning (DRL) to control the cooling setpoint (and hence cooling loads) of a large commercial building to harness energy flexibility. The research is motivated by the challenge associated with the development and application of conventional model-based control approaches at scale to the wider building stock. SAC is a model-free DRL technique that is able to handle continuous action spaces and which has seen limited application to real-life or high-fidelity simulation implementations in the context of automated and intelligent control of building energy systems. Such control techniques are seen as one possible solution to supporting the operation of a smart, sustainable and future electrical grid. This research tests the suitability of the SAC DRL technique through training and deployment of the agent on an EnergyPlus based environment of the office building. The SAC DRL was found to learn an optimal control policy that was able to minimise energy costs by 9.7% compared to the default rule-based control (RBC) scheme and was able to improve or maintain thermal comfort limits over a test period of one week. The algorithm was shown to be robust to the different hyperparameters and this optimal control policy was learnt through the use of a minimal state space consisting of readily available variables. The robustness of the algorithm was tested through investigation of the speed of learning and ability to deploy to different seasons and climates. It was found that the SAC DRL requires minimal training sample points and outperforms the RBC after three months of operation and also without disruption to thermal comfort during this period. The agent is transferable to other climates and seasons although further retraining or hyperparameter tuning is recommended.

description: We argue that the idea that the parton system created in relativistic heavy-ion collisions is formed in a state with transverse momenta close to thermodynamic equilibrium and its subsequent dynamics at early times is dominated by pure transverse hydrodynamics of the perfect fluid is compatible with the data collected at RHIC. This scenario of early parton dynamics may help to solve the problem of early equilibration.

description: We construct a simplex for multipartite qubit states of even number n of qubits, which has the same geometry concerning separability, mixedness, kind of entanglement, amount of entanglement and nonlocality as the bipartite qubit states. We derive the entanglement of the class of states which can be described by only three real parameters with the help of a multipartite measure for all discrete systems. We prove that the bounds on this measure are optimal for the whole class of states and that it reveals that the states possess only n-partite entanglement and not e.g. bipartite entanglement. We then show that this n-partite entanglement can be increased by stochastic local operations and classical communication to the purest maximal entangled states. However, pure n-partite entanglement cannot be distilled, consequently all entangled states in the simplex are n-partite bound entangled. We study also Bell inequalities and find the same geometry as for bipartite qubits. Moreover, we show how the (hidden) nonlocality for all n-partite bound entangled states can be revealed.

description: Giant radio relics are arc-like structures of diffuse, non-thermal synchrotron radiation that trace shock waves induced by galaxy cluster mergers. The particle (re-)acceleration mechanism producing such radio relics is unclear. One major open question is whether relics can be formed directly from a population of thermal seed electrons, or if pre-existing relativistic seed electrons are required. In some cases AGN can provide such a population of sub-GeV electrons. However, it is unclear how common this connection is. In this paper we present LOFAR 140 MHz and VLA L-band radio observations, as well as Chandra data of PSZ2 G096.88+24.18, a merging galaxy cluster system hosting a pair of radio relics. A large patch of diffuse emission connects a bright radio galaxy with one of the relics, likely affecting the properties of the relic. We find that the most plausible explanation for the connection is that the merger shock wave has passed over an AGN lobe. The shock passing over this seed population of electrons has led to an increased brightness in the relic only in the region filled with seed electrons.

description: We successfully fabricated interdigitated back-contact solar cells on n-type FZ-Si substrates with
silicon quantum dots as a down-shifting layer. The cells are fabricated using industrially available techniques such as
screen-printing, laser ablation, and conventional diffusion processes. The silicon quantum dots are formed on the
front side of the cells by thermal treatment of a silicon-rich-oxide layer during the fabrication process of the cells.
From photocurrent-voltage, quantum efficiency, and photoluminescence measurements of the IBC solar cells with Si-
QDs and reference cells without the QDs we have strong evidence that the down-shifting effect expected from QDs
works in the finished cells.

description: We introduce a new construction of $E_0$-semigroups, called generalized CCR flows, with two kinds of descriptions: those arising from sum systems and those arising from pairs of $C_0$-semigroups. We get a new necessary and sufficient condition for them to be of type III, when the associated sum system is of finite index. Using this criterion, we construct examples of type III $E_0$-semigroups, which can not be distinguished from $E_0$-semigroups of type I by the invariants introduced by Boris Tsirelson. Finally, by considering the local von Neumann algebras, and by associating a type III factor to a given type III $E_0$-semigroup, we show that there exist uncountably many type III $E_0$-semigroups in this family, which are mutually non-cocycle conjugate.

description: Impedance measurements have been performed on a sintered polycrystalline sample of the perovskite LaBiMn4/3Co2/3O6. Colossal dielectric permittivity often is measured in this class of semiconducting materials as a result of extrinsic factors. Our results show that a large offset in the capacitance, measured on a series of samples with different thickness, is due to the interfacial polarization. This contribution then can be removed from the data, creating a general procedure for dielectric measurements in semiconducting samples.

Silicon Solar Cell Characterization and Modelling

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1343-1346
description: To improve PV cell efficiency and reduce costs, intensive developments have been done concerning
the productivity of the furnace. The use of numerical tool gives precious information with regards to these
developments. Within the SEGSI project (2007-2011), financed by French National Research Agency, a complete 3D
numerical model of a 60kg crystallization silicon furnace has been developed using ANSYS 13.0 software. It is a
direct solidification furnace dedicated to laboratory experiments with two distinct heating zones. The model enables
to calculate the thermal of the furnace, the solidification rate and hydrodynamics of the silicon which are important in
order to control and improve the quality of the ingot during crystallization process. The purpose of this work is to
validate the time dependent heat transfer and hydrodynamic model with regards to experimental results. This
numerical tool is now available and is integrated in the development of new crystallization process.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 3041-3048
description: This paper presents the software developed by CENER in order to obtain maximum information from
EL technique applied to PV modules. By using the EL images of a PV module captured at different biasing levels,
application of the new software designed by CENER allows the extraction of important electrical information about
every individual cell in the module. In this way, using the software it is possible to obtain a map of the distribution of
the local series resistance in the cells, and also to extract an important part of the dark IV-curve of the cells to make
possible the detection of the potential shunted cells. Additionally, some experimental examples of the results of EL
technique applied to PV modules submitted to accelerated aging steps are also presented. In the cases where the
electrical response of the module is clearly modified after the stress tests, direct comparison of the EL images
obtained, before and after those tests, can be very helpful in order to establish the plausible physical origin of the
detected power degradation. CENER’s software is a supportive tool to assist in that task.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 772-774
description: Photoluminescence in Si wafers from band-to-band recombination is visually separated from luminescence
due to recombination through traps across the whole wafer surface using hyperspectral imaging. This technique yields images
of radiatively active recombination routes over the wafer with a highly resolved spectral third dimension. Crystal
imperfections in the material have been studied in the near infrared region 900-1700 nm, which includes the region of the so
called D-band emission lines. D-band emission lines are generally considered to be related to defects causing recombination
through radiatively active, relatively shallow bands, observable in the NIR region. Our images and spectra suggest that all the
D-band emission lines could have different origins. Hyperspectral PL imaging has been shown to be a powerful, nondestructive
method to study and discriminate between different radiative recombination mechanisms in silicon wafers.
Exploring the links between software development task type, team attitudes and task completion performance: Insights from the Jazz repository

description: Context: In seeking to better understand the impact of various human factors in software development, and how teams' attitudes relate to their performance, increasing attention is being given to the study of team-related artefacts. In particular, researchers have conducted numerous studies on a range of team communication channels to explore links between developers' language use and the incidence of software bugs in the products they delivered. Comparatively limited attention has been paid, however, to the full range of software tasks that are commonly performed during the development and delivery of software systems, in spite of compelling evidence pointing to the need to understand teams' attitudes more widely. Objective: We were therefore motivated to study the relationships between task type and team attitudes, and how attitudes expressed in teams' communications might be related to their task completion performance when undertaking a range of activities. Method: Our investigation involved artefacts from 474 IBM Jazz practitioners assembled in 149 teams working on around 30,000 software development tasks over a three-year period. We applied linguistic analysis, standard statistical techniques and directed content analysis to address our research objective. Results: Our evidence revealed that teams expressed different attitudes when working on various forms of software tasks, and they were particularly emotional when working to remedy defects. That said, teams' expression of attitudes was not found to be a strong predictor of their task completion performance. Conclusion: Efforts aimed at reducing bug incidence may positively limit teams' emotional disposition when resolving bugs, thereby reducing the otherwise high demand for emotionally stable members.

description: Detecting hot spots in PV using IR-imaging has become a valuable tool in the last years. Now, a remotecontrolled drone improves and facilitates the IR-mapping of PV-plants under operating conditions. In the course of this evaluation about 60 different PV-plants were investigated. The inspection time for a single PV-plant (5 kWp – 1000 kWp) took about 5 to 8 minutes. This included several IR-overviews and close-up views. Defects like disconnected strings,
substrings, shunted cells, faulty soldering and cell fracture could be visualized and distinguished. The data evaluation yielded a differentiation of cell defects by their temperature rise. In order to get a better understanding of the effects of the detected defects on the module performance, simulations with LTspice formed an essential part of this study. Thus, the influence on the power output of e. g. the size of the cell fracture or the number of shunted cells could be quantified.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 888-895
description: The interface passivation of a-AlOx/a-SiNx:H stacks deposited on p-type silicon by in-line plasma
enhanced chemical vapor deposition is investigated by means of charge carrier lifetime, field dependent surface
photovoltage and capacitance voltage measurements as well as Fourier transform infrared spectroscopy. To control
the quality of the interface, we performed different wet chemical surface preparation steps prior to a-AlOx/a-SiNx:H
stack deposition. Our investigation is focusing on the interface passivation upon post-deposition thermal treatments
such as annealing at 425 °C and firing at 860 °C as applied in the silicon solar cell industry. We demonstrate that the
interface recombination is mainly controlled by the interface state density as demonstrated by the correlation between
the surface recombination velocity and interface state density inferred from lifetime and SPV measurements. The
increase of the negative charge density after thermal steps as revealed by capacitance-voltage measurements
correlates with the increase of the density of negatively charged AlO4 tetrahedra as revealed by infrared spectroscopy
suggesting that the tetrahedrally coordinated Al contribute to the formation of the negative charge.

Instead of the modern decimal notation, which sees the use of comma to represent a number or a measure, at that time there was a wide use of fractions in calculations. The current work proposes that, through the cubit rod and its partitions of the finger into fractions, it could be possible to obtain very accurate measurements.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 4136-4139
description: Building-integrated photovoltaic (BIPV) systems are fast becoming an integral part of urban architecture in Europe. The need for accurate simulations of such systems is of paramount importance, both to provide credible predictions of energy generation, and to enable the establishment of appropriate standards. Here we
present a coupled thermal-electrical model of residential BIPV systems installed on rooftops with air cavities to cool PV modules by natural convection. The model was developed for use in the TRNSYS software environment, and validated using field monitoring data of 7 BIPV tests benches, representing 5 different systems commercially available in France in 2010. Relative differences exceeding 2% were observed for the thermal model and about 4% for the electrical power between measurements and simulation. The coupled model was accurate to 2% for sunny
days and less precise for partially cloudy days.

The following review provides an overview of the recent advances in the design, synthesis, and applications of macrocyclic receptors specifically tailored for anion recognition. The unique structural features of macrocycles, such as their well-defined structures and pre-organised binding sites, contribute to their exceptional anion-binding capabilities that have led to their application across a broad range of the chemical and biological sciences.

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Dwarf galaxies that come too close to larger galaxies suffer tidal disruption; the differential gravitational force between one side of the galaxy and the other serves to rip the stars from the dwarf galaxy so that they instead orbit the larger galaxy. This process produces "tidal streams" of stars, which can be found in the stellar halo of the Milky Way, as well as in halos of other galaxies. This chapter provides a general introduction to tidal streams, including the mechanism through which the streams are created, the history of how they were discovered, and the observational techniques by which they can be detected. In addition, their use in unraveling galaxy formation history and the distribution of dark matter in galaxies is discussed, as is the interaction between these dwarf galaxy satellites and the disk of the larger galaxy.

description: To an electron moving in free space an electric field appears as a magnetic field which interacts with and can reorient the electron spin. In semiconductor quantum wells this spin-orbit interaction seems to offer the possibility of gate-voltage control in spintronic devices but, as the electrons are subject to both ion-core and macroscopic structural potentials, this over-simple picture has lead to intense debate. For example, an externally applied field acting on the envelope of the electron wavefunction determined by the macroscopic potential, underestimates the experimentally observed spin-orbit field by many orders of magnitude while the Ehrenfest theorem suggests that it should actually be zero. Here we challenge, both experimentally and theoretically, the widely held belief that any inversion asymmetry of the macroscopic potential, not only electric field, will produce a significant spin-orbit field for electrons. This conclusion has far-reaching consequences for the design of spintronic devices while illuminating important fundamental physics.

description: George Orwell wrote several essays that mention the atomic bomb. This chapter examines these sources alongside Nineteen Eighty-Four to show that the atomic bomb was a structuring force for Orwell's novel and thought. Although Orwell died before the true implications of the Cold War -- a term he coined -- were felt, his prescient writing on nuclear war reverberate through his novel.

description: The possibility of reducing the process temperature during the deposition process below the values
currently needed for high quality CIGS deposition, while maintaining high conversion efficiency, was investigated.
The influence of the presence of Sb on the migration properties during CIGS growth is analyzed by SIMS
compositional depth profiles. The electronic properties of CIGS solar cells grown at low deposition temperatures with
and without Sb layer are evaluated by temperature dependent J-V and C-V measurements and discussed using
simulation of solar cells by SCAPS.

description: We discuss the production of top--anti-top quark pairs in association with a hard jet at the Tevatron and at the LHC and we report on the calculation of the next-to-leading order QCD corrections to this process. Numerical results for the top--anti-top+jet cross section and the forward--backward charge asymmetry are presented. The corrections stabilize the leading-order prediction for the cross section. In contrast, the charge asymmetry receives large corrections. The dependence of the cross section as well as the asymmetry on the minimum transverse momenta used to define the additional jet is studied in detail for the Tevatron.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 4140-4142
description: High penetration of variable renewable generation systems such as photovoltaic (PV) systems will cause
the issue of the supply-demand imbalance in a whole power system as well as voltage and power flow fluctuation in local
distribution systems. In the case, the output forecasting of PV system is one of the most important technologies in order
to make balance the supply-demand in the power system. The forecasting on the point is not only important, but also the
regional forecasting is much important in the case of disseminated large amount of PV systems in the future. In this study,
we aimed to confirm the smoothing effect on forecasting error in the regional. The correlation between forecasting error
and distance of point to points was evaluated due to identify spatially-uncorrelated with distance. If forecasting error each
point is spatially-uncorrelated, the regional forecasting error obeys the central limit theorem, and the limitation of
accuracy of PV power forecasting would be estimated. Figure shows one of the results of correlation between distance of
point to point and forecasting error in Japan. Forecasting data has better correction rather than measured data.
Forecasting error made by those relations. The correlation is immediately decreased within 100km.
Control of spin coherence in semiconductor double quantum dots

description: We propose a scheme to manipulate the spin coherence in vertically coupled GaAs double quantum dots. Up to {\em ten} orders of magnitude variation of the spin relaxation and {\em two} orders of magnitude variation of the spin dephasing can be achieved by a small gate voltage applied vertically on the double dot. Specially, large variation of spin relaxation still exists at 0 K. In the calculation, the equation-of-motion approach is applied to obtain the electron decoherence time and all the relevant spin decoherence mechanisms, such as the spin-orbit coupling together with the electron--bulk-phonon scattering, the direct spin-phonon coupling due to the phonon-induced strain, the hyperfine interaction and the second-order process of electron-phonon scattering combined with the hyperfine interaction, are included. The condition to obtain the large variations of spin coherence is also addressed.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1751-1754
description: To adopt a galvanic based Nickel seed layer front side metallization on an industrial manufacturing cell
concept several process steps had to be optimized related to plating. In this work relevant process steps have been
investigated with regard to their potential impact for galvanic based front side metallization. Starting with an
industrial standard process scheme for solar cells the not feasible processes are determined and alternatives will be
presented. The investigated impacts are the emitter formation the plasma enhanced chemical vapor deposition SiNx
anti-reflection coating (ARC) opening and the thermal contact formation [1]. A revised process scheme, involving an
adopt emitter profile based on a inline furnace emitter [2] and an SiNx ARC laser ablation, is introduced and first
solar cell results with 18.4% efficiencies are achieved with a fully plated, nickel based, front side metallization.

description: The specific absorption rate (SAR) of a dilute assembly of spherical iron nanoparticles with cubic anisotropy distributed in a viscous liquid is calculated using the solution of stochastic Landau - Lifshitz equation for unit magnetization vector and stochastic equations for multiple particle directors that specify the spatial orientation of the nanoparticle in a liquid. The viscous and magnetic magnetization reversal modes of particles are revealed at low and sufficiently high amplitudes of alternating magnetic field, respectively. The SAR of iron nanoparticle assembly is shown to exceed significantly that of iron oxide nanoparticles with uniaxial anisotropy at the same amplitudes and frequencies of applied magnetic field. The linear response theory is shown to be valid only at small magnetic field amplitudes, H0 < 50 - 70 Oe.

description: Trust in the energy generation potential and overall lifetime performance of PV technologies can be
achieved by demonstrating reliable outdoor performance. Long-term measurements in different climatic conditions
also help to create an understanding of the drivers governing the energy output globally.
Q.CELLS SE, one of the leading PV companies in the world, has been operating a high-class outdoor test facility
near its headquarters in Germany since summer 2009 [1,2]. Apart from the monitoring site in Thalheim, Germany an
ever increasing number of closely monitored reference systems around the world make it possible to extend this work
globally. The results from yield simulations using a modified one-diode model and an empirical model show an
agreement between simulation and measurements of higher than 2% for sites in Germany and Australia. Furthermore,
the effect of textured glass on the annual energy yield was found to be in a range of 2% for glass containing a pyramid
structure not accounting for soiling. PID effects due to a lack of functional grounding with negative potential at a
tropical site in Malaysia could not be observed for the anti PID Q.CELLS modules. Finally, irradiation histograms for
the sites discussed are presented illustrating the difference in operating conditions.
Properties of the Dwarf Galaxy Population in Galaxy Clusters

description: We present the observational properties of the dwarf galaxy population (Mr > M*+1) corresponding to one of the largest samples of spectroscopically confirmed galaxy cluster members reported in the literature. We have observed that red dwarf galaxies (u-r > 2.22) share the same cluster environment as the brightest cluster members (Mr < -21), but are not in dynamical equilibrium. We computed the dwarf-to-giant ratio (DGR) using a spectroscopically selected sample. The DGR was found to vary with clustercentric distance, essentially due to the blue dwarf population (u-r < 2.22). The u-r color of red dwarf galaxies was independent of their environment and similar to the color of red isolated dwarfs. Blue dwarf galaxies located outside r200 show similar u-r colors to those of the field population, while strong reddening was observed toward the cluster center. We also present evidence that the fraction of red to blue dwarf galaxies in clusters is larger in the innermost cluster regions. We conclude that the present red dwarf population observed in the central regions of nearby galaxy clusters could be related to the blue dwarf population observed in clusters at high redshift.
