description: For multilevel spin systems, robustness of the quantum mechanical (QM) violation of macrorealism (MR) with respect to coarse grained measurements is investigated using three different necessary conditions of MR, namely, the Leggett-Garg inequality (LGI), Wigner's form of the Leggett-Garg inequality (WLGI) and the condition of no-signalling in time (NSIT). It is shown that for dichotomic sharp measurements, in the asymptotic limit of spin, the algebraic maxima of the QM violations of all these three necessary conditions of MR are attained. Importantly, the QM violations of all these persist in that limit even for \textit{arbitrary} unsharp measurements, i.e. for any non zero value of the sharpness parameter characterizing the degree of fuzziness of the relevant measurements. We also find that when different measurement outcomes are clubbed into two groups for the sake of dichotomising the outcomes, the asymmetry/symmetry in the number of outcomes in the two groups, signifying the degree of coarse graining of measurements, has a crucial role in discerning quantum violation of MR. The results clearly demonstrate that classicality does not emerges in the asymptotic limit of spin, whatever be the unsharpness and degree of coarse graining of the measurements.

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 2783-2789
description: Solar photovoltaics (PV) is becoming the cheapest form of electricity generation in many sunny countries around the world. In some European countries with moderate annual solar irradiation, true competitiveness of solar PV has not yet been reached in all market segments. However, this competitiveness might be enhanced by using electricity storage. The challenge for PV generation is that it does not always match the electricity consumption. Especially in residential PV installations, a large share of the self-produced solar electricity cannot be immediately consumed locally, and is fed to the grid with very low remuneration. With storage, the share of PV self-consumption can be increased which could lead to a better business case for the prosumer. Currently, the average price of battery storage is still too high in most cases to make a PV system with storage competitive against PV without storage. However, in countries with high retail electricity price, like Italy and Germany, PV with storage is already becoming competitive. The continuing cost decrease of battery storage will soon make it a feasible option in more countries and will allow a higher share of PV generation in the energy system.

description: Energy system modellers typically choose a low spatial resolution for their models based on administrative boundaries such as countries, which eases data collection and reduces computation times. However, a low spatial resolution can lead to sub-optimal investment decisions for wind and solar generation. Ignoring power grid bottlenecks within regions tends to underestimate system costs, while combining locations with different wind and solar capacity factors in the same resource class tends to overestimate costs. We investigate these two competing effects in a capacity expansion model for Europe's power system with a high share of renewables, taking advantage of newly-available high-resolution datasets as well as computational advances. We vary the number of nodes, interpolating between a 37-node model based on country and synchronous zone boundaries, and a 1024-node model based on the location of electricity substations. If we focus on the effect of renewable resource resolution and ignore network restrictions, we find that a higher resolution allows the optimal solution to concentrate wind and solar capacity at sites with better capacity factors and thus reduces system costs by up to 10% compared to a low resolution model. This results in a big swing from offshore to onshore wind investment. However, if we introduce grid bottlenecks by raising the network resolution, costs increase by up to 23% as generation has to be sourced more locally at sites with worse capacity factors. These effects are most pronounced in scenarios where grid expansion is limited, for example, by low local acceptance. We show that allowing grid expansion mitigates some of the effects of the low grid resolution, and lowers overall costs by around 16%.

description: Market inventories have been made since fall 2011 for modules, inverters, and systems that are
available for purchase in the Netherlands to provide the fast growing Dutch market with proper market information.
The most recent inventory was made in December 2016. After the drop in module price in 2012 the average selling
price of modules has been found to stabilize, while inverter prices continue to decrease. PV system prices have
decreased considerably by ~20% since 2011, with some fluctuations. December 2016 average selling prices are 1.109
!/Wp and 0.29 !/Wp for modules and inverters, respectively, with 10-15% lower price for modules from China.
System prices have seen a temporary increase mid 2013 and 2016. Average installation costs amount to 0.34 !/Wp.
Grid parity is obvious: for a residential 2.5 kWp system the levelized cost of electricity (LCOE) is calculated to be
0.133 !/kWh for a system price of 1.77 !/Wp (including installation), based on an energy yield of 900 kWh/kWp, 25
years system lifetime, 3% discount rate, and 1% operation and maintenance (O&M) cost.

description: We study models in which the 750 GeV diphoton excess is due to a scalar decaying to two pseudo-Nambu-Goldstone bosons that subsequently decay into two pairs of highly boosted photons, misidentified as individual photons. Performing a model independent analysis we find that, with axion mass around $200$ MeV, this class of theories can naturally explain the observed signal with a large width, without violating monojet constraints. At the same time the requirement of a prompt axion decay can be satisfied only with a relatively large axion-photon coupling, leading to many new charged particles at the TeV scale. However, the required multiplicities of such fields is still moderately reduced relative to models with direct diphoton production.

description: Programmable data planes allow users to define their own data plane algorithms for network devices including appropriate data plane application programming interfaces (APIs) which may be leveraged by user-defined software-defined networking (SDN) control. This offers great flexibility for network customization, be it for specialized, commercial appliances, e.g., in 5G or data center networks, or for rapid prototyping in industrial and academic research. Programming protocol-independent packet processors (P4) has emerged as the currently most widespread abstraction, programming language, and concept for data plane programming. It is developed and standardized by an open community, and it is supported by various software and hardware platforms. In the first part of this paper we give a tutorial of data plane programming models, the P4 programming language, architectures, compilers, targets, and data plane APIs. We also consider research efforts to advance P4 technology. In the second part, we categorize a large body of literature of P4-based applied research into different research domains, summarize the contributions of these papers, and extract prototypes, target platforms, and source code availability. For each research domain, we analyze how the reviewed works benefit from P4's core features. Finally, we discuss potential next steps based on our findings.
Constraining Magnetization of Gamma-Ray Bursts Outflows using Prompt Emission Fluence

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: I consider here acceleration and heating of relativistic outflow by local magnetic energy dissipation process in Poynting flux dominated outflow. Adopting the standard assumption that the reconnection rate scales with the Alfven speed, I show here that the fraction of energy dissipated as thermal photons cannot exceed (13 $\hat γ-14)^{-1} = 30$% (for adiabatic index $\hat γ= 4/3$) of the kinetic energy at the photosphere. Even in the most radiatively efficient scenario, the energy released as non-thermal photons during the prompt phase is at most equal to the kinetic energy of the outflow. These results imply that calorimetry of the kinetic energy that can be done during the afterglow phase, could be used to constrain the magnetization of gamma-ray bursts (GRB) outflows. I discuss the recent observational status, and its implications on constraining the magnetization in GRB outflows.

description: Three real-lab trigeneration microgrids are investigated in non-residential environments (educational,
office/administrational, companies/production) with a special focus on domain-specific load characteristics. For
accurate load forecasting on such a local level, à priori information on scheduled events have been combined with
statistical insight from historical load data (capturing information on not explicitly-known consumer behavior). The
load forecasts are then used as data input for (predictive) energy management systems that are implemented in the
trigeneration microgrids. In real-world applications, these energy management systems must especially be able to
carry out a number of safety and maintenance operations on components such as the battery (e.g. gassing) or CHP
unit (e.g. regular test runs). Therefore, energy management systems should combine heuristics with advanced
predictive optimization methods. Reducing the effort in IT infrastructure the main and safety relevant management
process steps are done on site using a Smart & Local Energy Controller (SLEC) assisted by locally measured signals
or operator given information as default and external inputs for any advanced optimization. Heuristic aspects for local
fine adjustment of energy flows are presented.

description: The engineering of Majorana zero modes in topological superconductors, a new paradigm for the realization of topological quantum computing and topology-based devices, has been hampered by the absence of materials with sufficiently large superconducting gaps. Recent experiments, however, have provided enthralling evidence for the existence of topological surface superconductivity in the iron-based superconductor FeSe$_{0.45}$Te$_{0.55}$ possessing a full $s_\pm$-wave gap of a few meV. Here, we propose a mechanism for the emergence of topological superconductivity on the surface of FeSe$_{0.45}$Te$_{0.55}$ by demonstrating that the interplay between the $s_\pm$-wave symmetry of the superconducting gap, recently observed surface magnetism, and a Rashba spin-orbit interaction gives rise to several topological superconducting phases. Moreover, the proposed mechanism explains a series of experimentally observed hallmarks of topological superconductivity, such as the emergence of Majorana zero modes in the center of vortex cores and at the end of line defects, as well as of chiral Majorana edge modes along certain types of domain walls. We also propose that the spatial distribution of supercurrents near a domain wall is a characteristic signature measurable via a scanning superconducting quantum interference device that can distinguish between chiral Majorana edge modes and trivial in-gap states.

description: We exhibit a strong link between frequentist PAC-Bayesian risk bounds and the Bayesian marginal likelihood. That is, for the negative log-likelihood loss function, we show that the minimization of PAC-Bayesian generalization risk bounds maximizes the Bayesian marginal likelihood. This provides an alternative explanation to the Bayesian Occam's razor criteria, under the assumption that the data is generated by an i.i.d distribution. Moreover, as the negative log-likelihood is an unbounded loss function, we motivate and propose a PAC-Bayesian theorem tailored for the sub-gamma loss family, and we show that our approach is sound on classical Bayesian linear regression tasks.

description: CHEETAH is an FP7 integrated research project on photovoltaics funded by the European Commission
and was initiated by EERA PV. This project is structured into two type of activities: Coordinative and Support
actions (CSA) and Joint Research activities (JRA). The CSA focuses on the creation of a long term collaborative
platform by developing tools for knowledge sharing, e-learning platforms for training and education, mobility
between researchers, efficient use of infrastructures and promoting best practices and standards. The JRA focuses on
developing new concepts and technologies for wafer-based crystalline silicon PV (modules with thin cells < 100
micron), thin-film PV (advanced light management) and organic PV (very low-cost barriers), resulting in reduced
cost of environmentally benign/abundant/non-toxic materials and increased module performance. This paper gives a
summary of the main achievements of this project for the two categories of activities.

description: A magnetic skyrmion is a spin whirl with topological protection and high mobility to electric current. Intrinsic magnetoelastic coupling in chiral magnets permits manipulation of magnetic skyrmions and their lattice using mechanical loads, which is essential for developing future spintronics devices. It is found in experiments that the stability and deformation of skyrmions are sensitive to stresses, while the appearance of magnetic skyrmions in turn has a significant effect on the mechanical properties of the underlying material. However, a theory which explains these related phenomena within a unified framework is not seen. Here we construct a thermodynamic model for B20 helimagnets incorporating a magnetoelastic functional with necessary higher order interactions derived by group theory. Within the model, we establish the methodology to calculate the phase diagram and equilibrium properties of helimagnets under coupled temperature-magneto-elastic field. Applying the model to bulk MnSi, we calculate the temperature-magnetic field phase diagram under stress-free condition and its variation when uniaxial compression is applied. We also calculate the variation of all the elastic constants with magnetic field. The results obtained agree quantitatively with corresponding experiments. Our model provides a reliable basis for further theoretical studies concerning any magnetoelastic related phenomena in chiral magnets.

description: This paper aims to provide practitioners of causal mediation analysis with a better understanding of estimation options. We take as inputs two familiar strategies (weighting and model-based prediction) and a simple way of combining them (weighted models), and show how a range of estimators can be generated, with different modeling requirements and robustness properties. The primary goal is to help build intuitive appreciation for robust estimation that is conducive to sound practice. A second goal is to provide a "menu" of estimators that practitioners can choose from for the estimation of marginal natural (in)direct effects. The estimators generated from this exercise include some that coincide or are similar to existing estimators and others that have not previously appeared in the literature. We note several different ways to estimate the weights for cross-world weighting based on three expressions of the weighting function, including one that is novel; and show how to check the resulting covariate and mediator balance. We use a random continuous weights bootstrap to obtain confidence intervals, and also derive general asymptotic variance formulas for the estimators. The estimators are illustrated using data from an adolescent alcohol use prevention study.

description: Conventional photovoltaic (PV) systems are designed to compensate for the intermittent nature of solar
energy, and therefore require multiple power managing components like batteries and power converters. Each of
these components adds an additional cost and has an associated power loss. In this paper, we present a new topology
for photovoltaic systems. Instead of managing the power from the PV array, our system manages the loads and
matches them to the instantaneous maximum power available from the PV array. This results in a far simpler system
than conventional systems with a much higher efficiency and much lower cost. Several potential applications of this
system are discussed including electric vehicle charging and industrial electrolytic processes.

The first main result of the paper gives a necessary and a sufficient condition for sequences $a$ and $b$ which inform when $C(a )-C(b)$ is equal to $[-1,1]$ or is a finite union of closed intervals. One of the corollaries following from this results shows that the product of thicknesses of two central Cantor sets which algebraic difference is an interval may be arbitrarily small. We also show that there are sets $C(a)$ and $C(b)$ with the Hausdorff dimension equal to $0$ such that their algebraic difference is an interval. Finally, we give a full characterization of the case, when $C(a )-C(b)$ is equal to $[-1,1]$ or is a finite union of closed intervals.

description: Herein we develop a simple first-principles methodology to determine the modulation that vibrations exert on spin energy levels, a key for the rational design of high-temperature molecular spin qubits and single-molecule magnets. This methodology is demonstrated by applying it to [Cu(mnt)$_2$]$^{2-}$ (mnt$^{2-}$ = 1,2-dicyanoethylene-1,2-dithiolate), a highly coherent complex, using DFT to calculate the normal vibrational modes and wave-function based theory calculations to estimate the spin energy level structure. By theoretically identifying the most relevant vibrational modes, we are able to offer general strategies to chemically design more resilient magnetic molecules, where the qubit energy is not coupled to local vibrations.

description: This case study investigates the technical and economic potential of photovoltaic (PV) as main energy source of urban residential districts, considering sector coupling and a centralized district storage system (DSS). Therefore, load and PV generation profiles are modeled for a sector-coupled energy supply. Sector coupling includes the integration of heat pumps for the implementation of a power-to-heat concept and battery electric vehicles (BEV) for power-to-vehicle applications. Simulation results show the benefit of sector coupling and the need of DSS to optimize the self-consumption. The DSS supports the decentralization and self-sufficiency of the districts energy supply and provides flexibility by different operating strategies. The results of economic analysis point out that, under the investigated circumstance, LCOE (Levelized Costs of Electricity) of PV are in a competitive position with the current of price of electricity. Compared to the current EEG remuneration, the business model of “quarter electricity” (germ. Mieterstrom) provides the opportunity to increase the margin for providers and prosumers of PV. Additionally customers of urban electricity could benefit from lower prices of electricity and increase the acceptance of PV within urban residential districts. Moreover, the technical and economic potential for providers, consumers and prosumer of PV is shown.

shares of oil and gas to be displaced by solar energy with reference to savings. In view of plummeting costs for solar
photovoltaic (PV) energy, we find that displacing domestic use of oil and natural gas with solar energy in Qatar is costeffective
in most hydrocarbon price scenarios. Moreover, we find that it is more economical to displace more oil when
oil prices are higher (above $88/bbl) and to displace more gas at lower oil prices. Based on our findings, we recommend
that Qatar curtail electricity subsidies by aligning investments with return opportunities based on oil prices. Moreover,
we recommend avoiding further expansions in gas-fired power plants and instead investing in electric vehicle
infrastructure to continue promoting the growth of solar energy.

description: We prove the existence of semi-infinite geodesics for Brownian last-passage percolation (BLPP). Specifically, on a single event of probability one, there exist semi-infinite geodesics started from every space-time point and traveling in every asymptotic direction. Properties of these geodesics include uniqueness for a fixed initial point and direction, non-uniqueness for fixed direction but random initial points, and coalescence of all geodesics traveling in a common, fixed direction. Along the way, we prove that for fixed northeast and southwest directions, there almost surely exist no bi-infinite geodesics in the given directions. The semi-infinite geodesics are constructed from Busemann functions. Our starting point is a result of Alberts, Rassoul-Agha and Simper that established Busemann functions for fixed points and directions. Out of this, we construct the global process of Busemann functions simultaneously for all initial points and directions, and then the family of semi-infinite Busemann geodesics. The uncountable space of the semi-discrete setting requires extra consideration and leads to new phenomena, compared to discrete models.

description: Given its peak luminosity and early-time spectra, ASASSN-15lh was classified as the most luminous supernova (SN) ever discovered (Dong et al. 2016). Here we report a UV rebrightening of ASASSN-15lh observed with Swift during our follow-up campaign. The rebrightening began at $t \simeq$ 90 days (observer frame) after the primary peak and was followed by a $\sim 120$-day long plateau in the bolometric luminosity, before starting to fade again at $t\simeq 210$ days. ASASSN-15lh rebrightened in the Swift UV bands by $Δm_{UVW2} \simeq -1.75$ mag, $Δm_{UVM2} \simeq -1.25$ mag, and $Δm_{UVW1} \simeq -0.8$ mag, but did not rebrighten in the optical bands. Throughout its initial decline, subsequent rebrightening, and renewed decline, the spectra did not show evidence of interactions between the ejecta and circumstellar medium (CSM) such as narrow emission lines. There are hints of weak H$α$ emission at late-times, but Margutti et al. (2016) have shown that it is narrow line emission consistent with star formation in the host nucleus. By fitting a blackbody we find that during the rebrightening the effective photospheric temperature increased from $T_{BB} \simeq 11000$ K to $T_{BB} \simeq 18000$ K. Over the $\sim$ 550 days since its detection, ASASSN-15lh has radiated $\sim 1.7 - 1.9 \times 10^{52}$ ergs. Although its physical nature remains uncertain, the evolution of ASASSN-15lh's photospheric radius, its radiated energy, and the implied event rate, are all more similar to those of H-poor superluminous supernovae (SLSNe-I) than to tidal disruption events (TDEs).

description: 2016 was another record year for the solar industry, with yearly installations reaching 75 GWp, a global capacity installed exceeding 300 GWp, and power-purchase-agreement (PPA) prices beneath the symbolic value of $30/MWh. The levelized cost of energy (LCOE) generation is becoming a key metric to understand the economic and technological evolutions of solar energy. It has been the subject of numerous studies and is used by developers and investors to assess project worth. This paper presents our LCOE model for a 10-MWp ground-mount solar plant, using the results of interviews conducted with the stakeholders of the field during 2016-2017. Representative values for the capital investment, operating costs and means of financing were obtained, and the study focused on showing the impact of local factors, not only climatic, but also local economic and regulatory constraints. The results obtained for the LCOE varied between 30 and 70 €/MWh according to location showing good agreement with prices announced as part of 2016-2017 PPAs. In 2030, we estimate that this range will continue to decrease to reach values between 20 and 40 €/MWh with improvements due to increases in module efficiency, the increasing use of trackers and innovations such as bifacial modules.

description: The objective of this study is to assess the impact on energy performance of different architectural forms of BIPV systems integrated into parking lots and the influence of the electrical connection configurations. We made the analysis of a 450 kWp photovoltaic installation installed in the parking lot at Candido Portinari Park, in Sao Paulo/SP. We analyzed four different architectural canopy shapes: inclined flat; half-circle arc; quarter-circle arc and a "V" shaped format. Additionally we considered the tilt angles of 6°, 10° and 20° for inclined flat and "V" shape formats. PVsyst V6.38 simulation software provided the results that were analyzed based on three metrics: the total energy produced in kWh, specific production and performance ratio (PR). The results indicate that the most appropriate shape is the inclined flat canopy with 6° tilt angle. However, the quarter-circle arc and "V" format with tilt angle between 6° to 10° and inclined flat with tilt angle of 10° also showed total energy produced close to the inclined flat canopy with 6° tilt angle with a difference of -3.3%, -1.5%, -2.3% e -0.2% respectively, demonstrating that these are feasible BIPV architectural forms for this parking lot.

description: The transition from quantum to classical physics remains an intensely debated question even though it has been investigated for more than a century. Further clarifications could be obtained by preparing macroscopic objects in spatial quantum superpositions and proposals for generating such states for nano-mechanical devices either in a transient or a probabilistic fashion have been put forward. Here we introduce a method to deterministically obtain spatial superpositions of arbitrary lifetime via dissipative state preparation. In our approach, we engineer a double-well potential for the motion of the mechanical element and drive it towards the ground state, which shows the desired spatial superposition, via optomechanical sideband cooling. We propose a specific implementation based on a superconducting circuit coupled to the mechanical motion of a lithium-decorated monolayer graphene sheet, introduce a method to verify the mechanical state by coupling it to a superconducting qubit, and discuss its prospects for testing collapse models for the quantum to classical transition.

description: In this work, we give three new techniques for constructing Hermitian self-dual codes over commutative Frobenius rings with a non-trivial involutory automorphism using $λ$-circulant matrices. The new constructions are derived as modifications of various well-known circulant constructions of self-dual codes. Applying these constructions together with the building-up construction, we construct many new best known quaternary Hermitian self-dual codes of lengths 26, 32, 36, 38 and 40.

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 2815-2821
description: This paper provides an approach to calculate the technical and economic potential for photovoltaic (PV) power
generation in Lebanon and Jordan as an initial attempt to regionally quantify energy. The technical potential was
estimated using analytical and GIS (Geographic Information System) based methods having sets of constraints and
assumptions. Moreover, the economic potential is also estimated using GIS. The results of this study indicate a
calculated technical potential with a total of 21330 TWh/a in both Lebanon and Jordan compared to the analytically
calculated technical potential of 20941 TWh/a. As for the economically feasible energy production, the expected total
electricity production is 596 TWh/a. The GIS method provides a regional visualization of the potentials on the map
showing regions with high and low potentials. Having projects in the PV sector can clearly cover a significant share of
the demand, knowing that the economic potential in this approach shows an energy production with an order of
magnitude higher than the total electricity demand of 26.7 TWh/a. The concepts of technology readiness level (TRL)
together with the results obtained from the study motivate the introduction of a new concept in standardizing PV installed
capacity maturities called Regional Readiness Levels (RRL). The RRL notion ranks regions according to parameters
based on market potential of PV, aiming to overcome communication barriers within the PV community.

description: Motivated by the recent efforts to describe the gravitational interaction as a classical channel arising from continuous quantum measurements, we study what types of dynamics can emerge from a collisional model of repeated interactions between a system and a set of ancillae. We show that contingent on the model parameters the resulting dynamics ranges from exact unitarity to arbitrarily fast decoherence (quantum Zeno effect). For a series of measurements the effective dynamics includes feedback-control, which for a composite system yields effective interactions between the subsystems. We quantify the amount of decoherence accompanying such induced interactions, generalizing the lower bound found for the gravitational example. However, by allowing multipartite measurements, we show that interactions can be induced with arbitrarily low decoherence. These results have implications for gravity-inspired decoherence models. Moreover, we show how the framework can include terms beyond the usual second-order approximation, which can spark new quantum control or simulation protocols. Finally, within our simple approach we re-derive the quantum filtering equations for the different regimes of effective dynamics, which can facilitate new connections between different formulations of open systems.
