description: LSI +61 303 is one of the most interesting high-mass X-ray binaries owing to its spatially resolved radio emission and its TeV emission, generally attributed to non-thermal particles in an accretion-powered relativistic jet or in the termination shock of the relativistic wind of a young pulsar. Also, the nature of the compact object is still debated. Only LS 5039 and PSR B1259-63 (which hosts a non-accreting millisecond pulsar) have similar characteristics. We study the X-ray emission from LSI +61 303 covering both short-term and orbital variability. We also investigate the source spectral properties in the soft X-ray (0.3-10 keV) energy range. 25 snapshot observations of LSI +61 303 have been collected in 2006 with the XRT instrument on-board the Swift satellite over a period of four months, corresponding to about five orbital cycles. Since individual data sets have too few counts for a meaningful spectral analysis, we extracted a cumulative spectrum. The count rate folded at the orbital phase shows a clear modulation pattern at the 26.5 days period and suggests that the X-ray peak occurs around phase 0.65. Moreover, the X-ray emission appears to be variable on a timescale of ~1 ks. The cumulative spectrum is well described by an absorbed power-law model, with hydrogen column density Nh=(5.7+/-0.3)E+21 cm^-2 and photon index 1.78+/-0.05. No accretion disk signatures, such as an iron line, are found in the spectrum.

description: To reduce cost becomes a serious topic for all cell manufactures due to the continually increasing cost pressure from a significant decline in Average Selling Price (ASP) of solar cells. In this work, we developed a new AlOx paste named Non-PDA (NP) paste, which has the property of higher chemical reactivity. By using this NP paste, a AlOx film with good quality can be formed in just a few minutes via inline belt furnace and therefore the additional Post Deposition Annealing (PDA) step for further improving film quality is not necessary. An average efficiency of 21.66 % was demonstrated by using this PDA-free process. Although the efficiency was still 0.12 % less than that by using the standard process (with PDA), we found the PDA-free cells still had slight mist-like appearance on the rear. We think this unconformity in AlOx deposition as well as cell efficiency can be improved by further optimizing the thermal budget in the belt furnace or adjusting the chemical reactivity of NP paste.

description: We consider the problem of estimating a density $f_X$ using a sample $Y_1,...,Y_n$ from $f_Y=f_X\star f_ε$, where $f_ε$ is an unknown density. We assume that an additional sample $ε_1,...,ε_m$ from $f_ε$ is observed. Estimators of $f_X$ and its derivatives are constructed by using nonparametric estimators of $f_Y$ and $f_ε$ and by applying a spectral cut-off in the Fourier domain. We derive the rate of convergence of the estimators in case of a known and unknown error density $f_ε$, where it is assumed that $f_X$ satisfies a polynomial, logarithmic or general source condition. It is shown that the proposed estimators are asymptotically optimal in a minimax sense in the models with known or unknown error density, if the density $f_X$ belongs to a Sobolev space $H_{\mathbh p}$ and $f_ε$ is ordinary smooth or supersmooth.

description: In this paper, BIPV technology has been tested in desert environment located in Dubai, UAE for the year 2018. Two types of BIPV were installed in a cubic shape testing structure: CIGS and c-Si. The test structure is designed to evaluate the performance of the two technologies in facade facing east, south, west and zero-degree roof integration. The solar radiation and the performance of the panels were measured in all the four sides of the test structure over a period of one full year. This paper aims to provide an overall understanding of the actual BIPV performance data to architects in which they can use it as an input for their building design.
Adsorption of bovine serum albumin to polyethylene tubing reversibility and pH-dependence
Creators: name: Needham, Judy
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is concerned with the adsorption of bovine serum albumin to polyethylene tubing. A method using radioiodinated protein was developed to measure the surface concentration taking into account the dilution effect for miscible displacement in a capillary. A steady-state surface concentration was established within 2 hours. Adsorption did not depend on the ratio of radiolabelled to unlabel led protein. The adsorption isotherm was Langmuir-like with a plateau concentration of approximately 0.2 μg/cm². Two methods were used to calculate the surface concentration in the desorption study. The surface concentration calculated by depletion of the total radioactivity was always higher than that calculated from assaying the radioactivity associated with the tubing. Desorption of at least 5% of the loosely bound protein occurs. The surface concentration-pH data show two maxima. The first is at the isoelectric point of the albumin while the second is at pH 9.5-10. The second maximum seems to be due to preferential adsorption of the higher molecular weight oligomers in the protein sample.

description: Solar energy is promising renewable energy source for sustainable society. It is important to fill in the temporal and spatial gaps to utilize the solar energy effectively. This paper proposes novel framework to realize spatiotemporal shifting of solar energy using EVs. Since EV is equipped with very large battery for long cruise distance, EV can be realize as energy carrier along with carrying people and luggage. Proposed framework indirectly controls the EV's battery charge/discharge based on power trade via EV aggregator, and the spatiotemporal shifting of solar energy is realized in the end. Experimental results show the effectiveness of proposed framework.

PV Driven Energy Management and System Integration

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1681-1684
description: Effective utilization of renewable energy is a big motivation to renovate the conventional power systems toward smart energy systems. However, renewable energy is often small scale and intermittent. Hence, the online energy management is necessary to balance between demand and energy production. This paper proposes an online multi-scale optimization framework for smart PV systems in order to reduce the inherent complexity when trying solve the complete problem at a fine-grain time resolution. The proposed framework realizes the effective energy management by solving several optimization problems covering multi time scale. Experimental results shows that the proposed framework can reduce the purchased energy from the utility grid by 19.1% compared with other baseline methods.

Policies and Scenarios for Renewables, Societal and Global Challenges

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1906-1913
description: In 2016, the Australian Renewable Energy Agency’s Large-Scale Solar Funding Round provided over AU$90M in grant funding to eight separate developers to build twelve large-scale solar projects, where each developer was then obliged to share knowledge, insights and data in relation to the projects (one developer also agreed to share knowledge from two additional large-scale solar projects that did not receive funding). All 14 projects (the projects) successfully reached financial close and, as of August 2019, they are all generating electricity. This paper shares key information and presents the main successes and challenges experienced. Total project cost ranged from AU$1.82/WAC to AU$2.54/WAC, averaging 2% over-budget, and ranged from 16% under- to 25% over-budget. Compared to the project schedule from financial close, the projects reached practical completion, on average, over 38 weeks later than expected. Despite the common assumption of first-generation coinciding with full-generation, ramping-up took an average of 28 weeks to complete; eight of the projects proponents received payments for liquidated damages from the engineering, procurement and construction (EPC) contractors, totalling more than AU$40M; and 10 of the projects underestimated the impact of network loss adjustments. The leading cause of delays and cost overruns was associated with the increased complexity of grid connection, including verifying project grid models. Poor weather during construction and monitoring of progress and standards under EPC agreements were among some of the other major challenges.

description: Busbar-less type solar cells have been recently extensively developed, in order to improve the conversion efficiency. Although the current /voltage measurement of the solar cells are generally performed using a pin probe bar, the measurement results greatly fluctuate, because the contact is not stable. Solar cells with extremely thin busbars have been also developed for cost reduction, for which ensuring good contact using pin probe bars is becoming very difficult. In order to solve the problems, we have developed a new probe bar to measure those types of solar cells. Measurement of cells with a complicated electrode patterns is possible by making the contact from pin contacts to line contacts. We have obtained good measurement results for new types of cells, using the newly developed probe bar; FSS (Flexible Spring Suspension). The FSS can be installed to existing measurement sample stages with a holder we have designed, and can be implemented at a low cost. This solution is ideal for production line measurement.

description: We present the operational characteristics of a ramp rate control system on a 1 MW PV array located at Karratha Airport in Western Australia. The control system utilises cloud-prediction technology (CPT) to facilitate pre-emptive curtailment of the array, as well as a smoothing battery energy storage system (BESS), in order to meet ramp rate constraints required by Horizon Power, the local network operator. This project received funding under the Australian Renewable Energy Agency’s (ARENA) Regional Australia’s Renewables (RAR) initiative for the purposes of seeking to improve the competitiveness of renewable energy systems on the North-West Interconnected System (NWIS), and generating and sharing knowledge that will assist network operators and decision makers to better understand the economic value and technical viability of connecting distributed renewable energy generation on remote, stretched grids. Among the results shown are the observed reduction in ramp rates, the lost yield due to both curtailment and BESS losses, and the degree to which the BESS’s available power and energy capacity have been utilised. In addition, we present some of the key lessons learned during the commissioning process.

description: We derive an energy-dependent decay-time distribution function from the multi-exponential decay of the ensemble photoluminescence (PL) of InGaN/GaN quantum dots (QDs), which agrees well with recently published single-QD time-resolved PL measurements. Using eight-band k.p modelling, we show that the built-in piezo- and pyroelectric fields within the QDs cause a sensitive dependence of the radiative lifetimes on the exact QD geometry and composition. Moreover, the radiative lifetimes also depend heavily on the composition of the direct surrounding of the QDs. A broad lifetime distribution occurs even for moderate variations of the QD structure. Thus, for unscreened fields a multi-exponential decay of the ensemble PL is generally expected in this material system.

description: The IceCube neutrino detector is built into the Antarctic ice sheet at the South Pole to measure high energy neutrinos. For this, 4800 photomultiplier tubes (PMTs) are being deployed at depths between 1450 and 2450 meters into the ice to measure neutrino induced charged particles like muons. IceTop is a surface air shower detector consisting of 160 Cherenkov ice tanks located on top of IceCube. To extend IceTop, a radio air shower detector could be built to significantly increase the sensitivity at higher shower energies and for inclined showers. As air showers induced by cosmic rays are a major part of the muonic background in IceCube, IceTop is not only an air shower detector, but also a veto to reduce the background in IceCube. Air showers are detectable by radio signals with a radio surface detector. The major emission process is the coherent synchrotron radiation emitted by e+ e- shower particles in the Earths magnetic field (geosynchrotron effect). Simulations of the expected radio signals of air showers are shown. The sensitivity and the energy threshold of different antenna field configurations are estimated.

description: We test the gauge/gravity duality between the matrix model and type IIA string theory at low temperatures with unprecedented accuracy. To this end, we perform lattice Monte Carlo simulations of the Berenstein-Maldacena-Nastase (BMN) matrix model, which is the one-parameter deformation of the Banks-Fischler-Shenker-Susskind (BFSS) matrix model, taking both the large N and continuum limits. We leverage the fact that sufficiently small flux parameters in the BMN matrix model have a negligible impact on the energy of the system while stabilizing the flat directions so that simulations at smaller N than in the BFSS matrix model are possible. Hence, we can perform a precision measurement of the large N continuum energy at the lowest temperatures to date. The energy is in perfect agreement with supergravity predictions including estimations of α′-corrections from previous simulations. At the lowest temperature where we can simulate efficiently (T = 0.25λ1/3, where λ is the ’t Hooft coupling), the difference in energy to the pure supergravity prediction is less than 10%. Furthermore, we can extract the coefficient of the 1/N4 corrections at a fixed temperature with good accuracy, which was previously unknown.

description: We evaluated field-effect passivation of PECVD-grown silicon nitride (SiN) / ALD-grown aluminum oxide (AlO) stacks on crystalline Si with various SiN and AlO thickness by assessing terahertz (THz) emission using a laser-terahertz emission microscope (LTEM). LTEM was able to evaluate the field-effect passivation of the leaky passivation layer with Si-rich SiN film (n=2.1). The waveform and amplitude of the observed THz emission indicated that the Si surface was in the depletion mode with the AlO thickness up to 1 nm. The surface continuously transitioned to the accumulation mode with increasing AlO thickness. Holes accumulated strongly on the silicon surface above 3 nm, saturating the terahertz emission intensity. The observed continuous transition from depletion to accumulation showed that the SiN has negative charge and positive charge in AlO is required to achieve hole accumulation. When the AlO thickness was 1 nm, the Si surface was near the flatband condition regardless of the thickness of SiN. The observed consistency against the SiN thickness indicates that the positive charge in SiN exists locally near the SiN/AlO interface. The observed results showed that the AlO thickness more than 3 nm is essential in terms of electrical passivation in our growing conditions.

description: The STAR experiment at the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) is carrying out a spin physics program colliding transverse or longitudinal polarized proton beams at $\sqrt{s}=200-500 $GeV to gain a deeper insight into the spin structure and dynamics of the proton. These studies provide fundamental tests of Quantum Chromodynamics (QCD). One of the main objectives of the STAR spin physics program is the determination of the polarized gluon distribution function through a measurement of the longitudinal double-spin asymmetry, $A_{LL}$, for various processes. Recent results will be shown on the measurement of $A_{LL}$ for inclusive jet production, neutral pion production and charged pion production at $\sqrt{s}=200 $GeV. In addition to these measurements involving longitudinal polarized proton beams, the STAR collaboration has performed several important measurements employing transverse polarized proton beams. New results on the measurement of the transverse single-spin asymmetry, $A_{N}$, for forward neutral pion production and the first measurement of $A_{N}$ for mid-rapidity di-jet production will be discussed.

description: UNSW has demonstrated a world record conversion efficiency of 40.6% with a spectrum splitting concentrator photovoltaic (CPV) submodule, using a 150-layer dielectric bandpass filter to divert the 900-1050 nm spectral band from a triple junction solar cell (TJSC) to a Si cell. Instead of using a separate dielectric filter, we propose a more cost-effective approach, namely the integration of an intermediate distributed Bragg reflector (DBR) during TJSC fabrication, optimised to function as a suitable band-reflect filter. Spectrum splitting DBRs were incorporated into AZUR SPACE’s commercial CPV cells, to divert otherwise wasted light to Si solar cells. Our simulations show that 4-junction (TJSC + Si) spectrum-splitting receivers have higher efficiency (38.3+3.2=41.5%) than the original TJSCs (39.1%). The intermediate DBR approach also shows the advantage of a greatly reduced AOI dependence compared to a discrete dielectric filter, which could enhance the benefits of spectrum splitting.

For the non-laser LIR PERC cells, it can be found that the time of the recovery of light induced degradation (LID) shrinks down to 4hrs at elevated temperature 130°C under 1.5 sun. For the laser LIR PERC cells, it shown that the extent of the degradation after cycles of dark annealing and light soaking was still exists, the hydrogenation tool cannot completely eliminate excess hydrogen. It also indicated the 14s treatment time of laser LIR parameter is the best parameter than others time in this work. It could be demonstrated that the accelerated LID effect can be observed under high intensity and high temperatures conditions.

description: We consider a model inspired by a metal break-junction hypothetically caught at its breaking point, where the non-adiabatic center-of-mass motion of the bridging atom can be treated as a two-level system. By means of Numerical Renormalization Group (NRG) we calculate the influence of the two level system on the ballistic conductance across the bridge atom. The results are shown to be fully consistent with a conformal field theory treatment. We find that the conductance, calculated by coupling Fermi liquid theory to our NRG is always finite and fractional at zero temperature, but drops quite fast as the temperature increases.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a simple, testable, SU(5) model within the context of the type II neutrino see-saw mechanism. It is based on requiring renormalizability, the absence of any other matter fields besides those already present in the Standard Model and consistency with all experimental data. These "minimal" requirements, together with group-theoretical considerations, uniquely determine the model and lead to interesting implications. The model predicts correlation between a light SU(2) triplet boson responsible for the type II see-saw mechanism and observable proton decay signatures. It also allows for an enhanced production of doubly charged Higgs particles through the WW fusion process due to a built-in custodial symmetry. This could also have profound impact on the explicit realization of electroweak symmetry breaking. The model also predicts the existence of a light scalar that transforms as a colour octet and electroweak doublet, with interesting phenomenological consequences.

Despite their classical origin, these echoes persist deep into the quantum (perturbative) regime and can be described by an improved random matrix modeling. In the opposite limit of strong perturbations (and high enough energies), classical considerations reveal the importance of self-trapping phenomena in the echo efficiency.

description: The quantum teleportation with noisy EPR state is discussed. Using an optimal decomposition technique, we compute the concurrence, entanglement of formation and Groverian measure for various noisy EPR resources. It is shown analytically that all entanglement measures reduce to zero when $\bar{F} \leq 2/3$, where $\bar{F}$ is an average fidelity between Alice and Bob. This fact indicates that the entanglement is a genuine physical resource for the teleportation process. This fact gives valuable clues on the optimal decomposition for higher-qubit mixed states. As an example, the optimal decompositions for the three-qubit mixed states are discussed by adopting a teleportation with W-state

description: Entropic dynamics is a framework for defining dynamical systems that is aligned with the principles of information theory. In an entropic dynamics model for motion on a statistical manifold, we find that the rate of changes for expected values is linear to the gradient of entropy with reciprocal (symmetric) coefficients. Reciprocity principles have been useful in physics since Onsager. Here we show how the entropic dynamics reciprocity is a consequence of the information geometric structure of the exponential family, hence it is a general property that can be extended to a broader class of dynamical models.

description: In this work, we propose to use the copper accelerated acetic acid salt spray (CASS) test accelerated the salt mist corrosion test (IEC 61701), because there have been many reports recently that the module system in the coastal zone has been affected by corrosion. It implied the level 6 salt mist corrosion test is not enough in the coast with High temperature and humidity. The CASS test is for small moudles and aluminum frame. For the small module, we use different different materials under 24 day CASS test. It can be found the CASS test has little effect on the small module without the aluminum frame. For the aluminum frame, we have aluminum frame with different coating methods and conditions which under 6, 15, 20 and 24 days CASS test, and analyze the appearance and corrosion results. It can be observed that the general module aluminum frame shown minor pitting in 6 days. It means the aluminum frame with general condition is not resistant to the corrosion in this environment condition. Besides, the observation of the corrosion condition of the aluminum frame is not the traditional uniform corrosion, which is mainly for the pitting. The aluminum frame samples with traditional anodized coatings are less resistant to high corrosive environments.

description: The outcome statistics of an informationally complete quantum measurement for a system in a given state can be used to evaluate the ensemble expectation of any linear operator in the same state, by averaging a function of the outcomes that depends on the specific operator. Here we introduce two novel data-processing strategies, non-linear in the frequencies, which lead to faster convergence to theoretical expectations.

description: The market demands processes with high-throughput for the deposition of passivation layers for PERC solar cells. Inline PECVD tools are using multiple plasma sources with separately controllable process parameters in series for a stepwise controlled deposition of a layer, in example a silicon nitride layer. Accordingly, the final passivation layer consists of multiple sublayers with thicknesses in the range of several nanometers. The composition and thickness of these sublayers is crucial and define the properties of the full layer stack. A detailed time-of-flight secondary ion mass spectrometry (ToF-SIMS), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) study has been conducted on a SixNy:H/AlxOy passivation layer stack. Samples with different deposition sequences of plasma sources have prepared to investigate the depth-resolved composition of sublayers in the SixNy:H layer. ToF-SIMS was evaluated as a fast technique with high sensitivity to depth-dependent composition variations. Slight changes in the Si/N-ratio correlate with respect to the location of the sample to the plasma source position. Differences in the sublayer’s chemical composition can be resolved and clearly attributed to a single plasma source. This analytical approach allows a detailed process monitoring of each plasma source and could help to improve sophisticated gradient layer systems.

description: Soiling is strongly affected by a surface’s tilt angle: less dust accumulates at steep angles, and more dust resuspends by tilting toward the wind. One concept then to reduce PV soiling is to stow 1-axis trackers vertically or upside-down at night. A further concept is to use windy periods to partially clean the modules, by tilting the tracker at an angle that maximizes dust resuspension. These concepts were tested experimentally using 10 cm glass coupons and full-size PV modules, on custom-built 1-axis trackers, at a field station in Doha, Qatar. With coupons, stowing vertically at night reduced soiling by 41% on average, and upside-down by a further 9%. However attempts to enhance dust resuspension during windy periods were largely ineffective (and would also sacrifice irradiation harvest). The average results for full-size modules were similar to the average results for coupons, but they differed significantly for individual test rounds. Overall the study showed that modifying 1-axis PV trackers to stow at ≥90° at night could significantly reduce PV soiling in desert environments, but using trackers to promote wind cleaning does not appear promising.
An approach to anomalies in M-theory via KSpin

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The M-theory fieldstrength and its dual, given by the integral lift of the left hand side of the equation of motion, both satisfy certain cohomological properties. We study the combined fields and observe that the multiplicative structure on the product of the corresponding degree four and degree eight cohomology fits into that given by Spin K-theory. This explains some earlier results and leads naturally to the use of Spin characteristic classes. We reinterpret the one-loop term in terms of such classes and we show that it is homotopy invariant. We argue that the various anomalies have natural interpretations within Spin K-theory. In the process, mod 3 reductions play a special role.

Antimatter Signatures of Gravitino Dark Matter Decay

description: The scenario of gravitino dark matter with broken R-parity naturally reconciles three paradigms that, albeit very well motivated separately, seem to be in mutual conflict: supersymmetric dark matter, thermal leptogenesis and standard Big Bang nucleosynthesis. Interestingly enough, the products of the gravitino decay could be observed, opening the possibility of indirect detection of gravitino dark matter. In this paper, we compute the positron and the antiproton fluxes from gravitino decay. We find that a gravitino with a mass of 150 GeV and a lifetime of 10^26 s could simultaneously explain the EGRET anomaly in the extragalactic diffuse gamma ray background and the HEAT excess in the positron fraction. However, the predicted antiproton flux tends to be too large, although the prediction suffers from large uncertainties and might be compatible with present observations for certain choices of propagation parameters.

description: Current-voltage (I-V) curve measurement is an important characterisation technique for evaluating the behaviour and performance of solar cells and modules. From these I-V measurements, device and performance parameters, which give a basic indication of the functioning of the device, can be extracted. Point-by-point I-V curve measurements of a mc-Si solar cell were obtained using the Light Beam Induced Current (LBIC) imaging technique. A parameter extraction method based on the interval division algorithm was applied to the measurements to extract point-by-point device and performance parameters. The extracted parameters showed variations which could be attributed to spatial non-uniformities in the local properties of the device that determine its performance. By incorporating a reflection detector in the measurment system, current reducing defects within the bulk of the device were distnguished from optical blockages on the solar cell surface.

We introduce a procedure based on thresholding on a new type of spherical wavelets called {\it needlets}. We establish a minimax result and prove its optimality. We are motivated by astrophysical applications, in particular in connection with the analysis of ultra high energy cosmic rays.

description: We study the properties of configurations from which P-vortices on one hand or Abelian monopoles on the other hand have been removed. We find that the zero modes and the band of non-zero modes close to zero disappear from the spectrum of the overlap Dirac operator, confirming the absence of topological charge and quark condensate. The different behavior of the modified ensembles under smearing compared to the unmodified Monte Carlo ensemble corroborates these findings. The gluonic topological susceptibility rapidly approaches zero in accordance with Q_{index}=0. The remaining (ultraviolet) monopoles without vortices and -- to a less extent -- the remaining vortices without monopoles are unstable under smearing whereas smearing of the unmodified Monte Carlo ensemble effects the monopoles and vortices only by smoothing, reducing the density only slightly.
