Still life : the life of things in the fiction of Patrick White
Creators: name: Whaley, Susan Jane
Publisher: name: University of British Columbia
Year: 2010

description: "Still Life" argues that Patrick White's fiction reveals objects in surprising, unexpected attitudes so as to challenge the process by which the mind usually connects with the world around it. In particular, White's novels disrupt readers' tacit assumptions about the lethargic nature of substance; this thesis traces how his fiction reaches beyond familiar linguistic and stylistic forms in order to reinvent humanity's generally passive perception of reality. The first chapter outlines the historical context of ideas about the "object," tracing their development from the Bible through literary movements such as romanticism, symbolism, surrealism and modernism. Further, the chapter considers the nature of language and the relation of object to word in order to distinguish between the usual symbolic use made of objects in literature and White's treatment of things as discrete, palpable entities. The second chapter focuses on White's first three published novels—Happy Valley (1939), The Living and the Dead (1941) and The Aunt's Story (1948)--as steps in his novelistic growth. Chapters Three, Four and Five examine respectively The Tree of Man (1955), The Solid Mandala (1966) and The Eye of the Storm (1973); these novels represent successive stages of White's career and exemplify his different formal and stylistic techniques. White's innovations demand a new manner of reading; therefore, each novel is discussed in terms of objects which reflect the shapes of the works themselves: "tree" defines the structure and style of Tree of Man "house" inspires Solid Mandala and "body" shapes Eye of the Storm. Reading White's novels in terms of structural analogues not only illuminates his methodology, but also clarifies his distinction between objective and subjective ways of understanding the world. Further, these chapters also refute critics' arguments that White's objects are merely victims of his overambitious use of personification and pathetic fallacy, or that they are the result of his dabbling in mysticism. "Still Life" concludes by showing how Patrick White's novels sequentially break down assumptions about reality and appearance until the reality of language itself falters. The author restores mystery to things by relocating the possibility of the extraordinary within the narrow, prescribed confines of the ordinary. White succeeds in changing readers' notions about the nature of reality by disrupting the habitual process by which they apprehend the world of things.

description: We study geometrically thick perfect-fluid tori with constant specific angular momentum, so-called "Polish doughnuts", orbiting deformed compact objects with a quadrupole moment. More specifically, we consider two different asymptotically flat, static and axisymmetric vacuum solutions to Einstein's field equation with a non-zero quadrupole moment, the q-metric and the Erez-Rosen spacetime. It is our main goal to find features of Polish doughnuts in these two spacetimes which qualitatively distinguish them from Polish doughnuts in the Schwarzschild spacetime. As a main result we find that, for both metrics, there is a range of positive (Geroch-Hansen) quadrupole moments which allows for the existence of double tori. If these double tori fill their Roche lobes completely, their meridional cross-section has the shape of a fish, with the body of the fish corresponding to the outer torus and the fish-tail corresponding to the inner torus. Such double tori do not exist in the Schwarzschild spacetime.

description: Photovoltaic (PV) will play a major role in the global Energiewende. Especially on Caribbean islands it
is the most promising power generation technology based on high solar radiation, easy scaling and expensive
conventional diesel power generation. Even though PV is economically competitive on almost all Caribbean islands,
it has only been significantly installed on islands with regulatory frameworks such as feed-in tariffs or net metering
schemes. Within this work the benefits of net-billing schemes (feed-in tariff below the retail price) are analyzed for
the Caribbean along the example of St Vincent. The analysis shows that this framework offers a huge economic and
ecological potential extending St Vincent’s power generation with PV. By choosing the optimized net-billing tariff
private investors, the utility, consumer and the entire economy of St Vincent can profit.

description: Anthocyanin-rich fruit beverages are of special interest as functional products due to their antioxidant activity, antimicrobial properties against pathogens, and, more recently, evidence of prebiotic potential. The stability and bioactivity of anthocyanins, probiotics, prebiotics, and synbiotics have been extensively documented in beverage models and reviewed separately. This review summarizes the most recent works and methodologies used for the development of probiotic and synbiotic beverages based on anthocyanin-rich fruits with a synergistic perspective. Emphasis is made on key optimization factors and strategies that have allowed probiotic cultures to reach the minimum recommended doses to obtain health benefits at the end of the shelf life. The development of these beverages is limited by the high acidity and high content of phenolic compounds in anthocyanin-rich fruits. However, a proper selection of probiotic strains and strategies for their media adaptation may improve their viability in the beverages. Fermentation increases the viability of the probiotic cultures, improves the safety and stability of the product, and may increase its antioxidant capacity. Moreover, fermentation metabolites may synergistically enhance probiotic health benefits. On the other hand, the inoculation of probiotics without fermentation allows for synbiotic beverages with milder changes in terms of physicochemical and sensory attributes.

description: The market price of Ag has fluctuated 10X over the past 10 years and has impacted the manufacturing
cost of Si solar cells and the price of Si PV. Reduction of Ag consumption can decrease this cost, however, such
reduction may come at the expense of cell performance. In order to address the issue of Ag cost reduction while
maintaining high cell efficiency, we tailored phosphorus emitter profiles via POCl3 diffusion to create solar cell
emitters displaying low saturation current density (J0e), variable electrically active surface phosphorus concentration
([Psurface]), and variable sheet resistance with the aim of reducing Ag consumption. By optimizing emitter diffusion
conditions, we were able to reduce screen-printed Ag paste consumption by 40 – 60% with no loss in cell
performance. Using a screen-printable Ag conductor paste designed to contact low [Psurface] emitters, we compared
the performance of cells with screen-printed Ag paste dry masses of 200, 120, and 80 mg. Using a tailored Low J0e 55
Ω/sq emitter, high open circuit voltage (VOC) and short circuit current (JSC) are achieved to give average cell
efficiencies of 18.64% and 18.73% for 120 mg and 80 mg Ag paste dry mass, respectively. This is compared to
efficiencies of 18.52% and 18.21% for cell using industrial-type 65 Ω/sq emitter with 120 and 80 mg Ag paste dry
mass, respectively. Based on US$32/Troy oz. Ag market price and 85% by weight thick film paste Ag metal content,
Ag front side metallization cost of US¢2.11/W can be achieved by using 80 mg Ag paste dry mass. This is compared
to US¢3.19/W (33% cost savings) and US¢5.44/W (60% cost savings) for use of 120 and 200 mg Ag paste dry mass,
respectively, on industrial-type emitter.

description: Theoretical evidence and previous studies suggest that oralnutrient supplementation (ONS) with n-3 fatty acids for rheumatoid arthritis (RA) has the potential to lower disease activity indicators and non-steroidal anti-inflammatory drug (NSAID) uptake. A systematic search was conducted on five databases/registries from inception until May 23, 2021 with the aim to identify randomized placebo-controlled trials comparing n-3 supplements to placebo on disease-specific outcomes. A total of 23 studies matched the criteria (PROSPERO: CRD42019137041). Pooled analyses revealed that n-3 ONS provided a small effect in reducing pain [standardized mean difference (SMD): −0.16, 95% confidence intervals (CI): −0.40 to 0.09], and tender (SMD: −0.20, 95% CI: −0.46 to 0.05) and swollen joint count (SMD: −0.10, 95% CI: −0.28 to 0.07). In sensitivity analyses, there was a small effect in the reduction of NSAIDs intake (SMD: −0.22, 95% CI: −0.90 to 0.46), and c-reactive protein was reduced only by 0.21 mg/dL (95% CI: −0.75 to 0.33). Similar findings were observed regarding other objective/subjective outcomes. The certainty of the evidence was mostly of “very low/low” quality. Overall, n-3 ONS in RA might have a limited clinical benefit. Previous findings suggesting a reduction in NSAID intake may have been biased from the inadequate blinding of interventions.

description: Oerlikon Solar is the leading provider of thin film (TF) Silicon PV module manufacturing lines. At
the core of such manufacturing line is the PECVD tool – a system named KAI MT. It utilizes very high frequency
(VHF 40.68 MHz) capacitively coupled plasma (CCP) reactor which has been fundamentally renewed in
2011/2012; mainly the inter-electrode gap is reduced. The reduced gap or narrow gap reactor allows us to use
significantly increased process pressures for microcrystalline and amorphous Silicon deposition. Control of the
electrode gap is then an important factor for limiting the effect of powder production, enhancing the deposition
rates, and maximizing the SiH4 usage efficiency. NF3 consumption during cleaning is also reduced. The potential
of the new high pressure deposition regime has previously been shown on basis of test cells results which show
an up to 40% increased efficiency of μc-Si bottom cells [2]. The paper now presents device grade single junction
a-Si modules and tandem mini modules which are deposited at high rate (0.6nm/s or higher) and high pressure
using such a reactor.

description: Zero-shot learning (ZSL) aims to discriminate images from unseen classes by exploiting relations to seen classes via their attribute-based descriptions. Since attributes are often related to specific parts of objects, many recent works focus on discovering discriminative regions. However, these methods usually require additional complex part detection modules or attention mechanisms. In this paper, 1) we show that common ZSL backbones (without explicit attention nor part detection) can implicitly localize attributes, yet this property is not exploited. 2) Exploiting it, we then propose SELAR, a simple method that further encourages attribute localization, surprisingly achieving very competitive generalized ZSL (GZSL) performance when compared with more complex state-of-the-art methods. Our findings provide useful insight for designing future GZSL methods, and SELAR provides an easy to implement yet strong baseline.

description: Threats from Africa undermine the security of Europe. The European Union and NATO have 22 member countries in common, namely most of EU member states. The fundamental role of the Atlantic Alliance is to safeguard the freedom and security of its member countries by political and military means.

Since the fall of the Berlin Wall, non-state actors and hybrid threats emerged as the major challenges to international security. NATO is evolving in response to new strategic reality, and terrorism and weak states are among the most pressing challenges the Alliance faces. NATO is playing an increasingly important role in crisis management and peacekeeping.

Since the African Union was established in 2001 as the successor to the Organization of African Unity,it faces difficulties in achieving the African ownership in peace and security. The chronic lack of funding and of appropriate military resources, makes the African Union depending on external aid –NATO provides military support, while the EU provides money. NATO cooperates with the AU since 2005, and all NATO-AU activities are coordinated with the EU.

The NATO-EU partnership is complementar and mutual, and is based on common values and strategic interests, and should be strengthened to secure the European southern border, and to guarantee security in the Mediterranean region. Therefore, stronger and permanent NATO–EU partnership in Africa would be desirable. This brief paper investigates the ties between these three organizations, and suggests some recommendations to improve the 'trilateral' relationship to ensure security to their member states.

description: We study the variability of the warm absorber and the gas responsible for the emission lines in the Seyfert 1 galaxy NGC 5548, in order to constrain the location and physical properties of these components. Using X-ray spectra taken with the \textit{Chandra}$-$LETGS in 2002 and 2005, we study variability in the ionic column densities and line intensities. We find a lower \ion{O}{vii} forbidden emission line flux in 2005, while the Fe K$α$ line flux stays constant. The warm absorber is less ionized in 2005, allowing us to constrain its location to within 7 pc of the central source. Using both the observed variability and the limit on the FWHM of the \ion{O}{vii} f line, we have constrained the location of the narrow line region to a distance of 1 pc from the central source. The apparent lack of variability of the Fe K$ α$ line flux does not allow for a unique explanation.

description: The review presents general methods for treating complicated problems that cannot be solved exactly and whose solution encounters two major difficulties. First, there are no small parameters allowing for the safe use of perturbation theory in powers of these parameters, and even when small parameters exist, the related perturbative series are strongly divergent. Second, such perturbative series in powers of these parameters are rather short, so that the standard resummation techniques either yield bad approximations or are not applicable at all. The emphasis in the review is on the methods advanced and developed by the author. One of the general methods is {\it Optimized Perturbation Theory} now widely employed in various branches of physics, chemistry, and applied mathematics. The other powerful method is {\it Self-Similar Approximation Theory} allowing for quite simple and accurate summation of divergent series. These theories share many common features with the method of renormalization group, which is briefly sketched in order to stress the similarities in their ideas and their mutual interconnection.

description: Solutions to overcome the damage of passivation layers caused by DC-sputtering of metal layers are
presented. Previous works showed that DC-sputtering of metal layers causes major damage to the underlying
passivation layer due to bombardment with radiation in the soft X-ray regime. However, the sputter-induced damage
can be reversed by a post-metallization annealing step. In this work we established solutions for non-damaging
sputtering processes without the requirement of a post-metallization annealing step which can lead to time and cost
savings during silicon solar cell production. We carried out our investigations on various metal layers sputtered on
different passivation layers using the Solaris system of OC Oerlikon Balzers Ltd. We show that a non-damaging
sputtering process can be achieved either by sputtering at high temperatures or by choice of passivation and cap
layers.

description: The folded spinning string in AdS3 gives us an important insight into AdS/CFT duality. Recently its one-loop energy was analyzed in the context of AdS4/CFT3 by McLoughlin and Roiban arXiv:0807.3965, by Alday, Arutyunov and Bykov arXiv:0807.4400 and by Krishnan arXiv:0807.4561. They computed the spectrum of the fluctuations around the classical solution. In this paper we reproduce their results using the algebraic curve technique and show that under some natural resummation of the fluctuation energies the one-loop energy agrees perfectly with the predictions of arXiv:0807.0777. This provides a further support of the all-loop Bethe equations and of the AdS4xCP3 algebraic curve developed in arXiv:0807.0437.

description: The application of high-dimensional quantum systems (qudits) in quantum computing and communications seems to be a promising avenue due to the possibility of increasing the amount of information encoded in one physical carrier. In this work, we propose a method for implementing single-qudit gates for qudits based on light modes with orbital angular momentum. Method for logical qudits encoding, which ensures the quasi-cyclicity of operations, is introduced. Based on the protocol for converting the orbital angular momentum of light in the Raman quantum memory scheme [Vashukevich E.A. et. al. PRA, 101, 033830 (2020)], we show that the considered gates provide an extremely high level of fidelity of single-qudit transformations. We also compare quantum gates' properties for systems of different dimensions and find the optimal conditions for carrying out transformations in the protocol under consideration.

description: We study quantum Maxwell's demon in a discrete space-time setup. We consider a collection of particles hopping on a one-dimensional chain and a semipermeable barrier that allows the particles to hop in only one direction. Our main result is a formulation of a local unitary dynamics describing the action of this barrier. Such dynamics utilises an auxiliary system $\mathcal{A}$ and we study how properties of $\mathcal{A}$ influence the behaviour of particles. An immediate consequence of unitarity is the fact that particles cannot be trapped on one side of the barrier forever, unless $\mathcal{A}$ is infinite. In addition, coherent superpositions and quantum correlations are affected once particles enter the confinement region. Finally, we show that initial superposition of $\mathcal{A}$ allows the barrier to act as a beam splitter.

description: MicroRNAs (miRNAs) are potentially involved in the regulation of glucose and lipid metabolism. The aim of this study was to investigate potential miRNA regulators for serum lipids and blood glucose in gestational diabetes mellitus. Plasma samples were obtained from 53 women with GDM and 46 normal pregnant women. Fasting blood glucose and a blood lipid profile were measured. Plasma miRNA expression profiles were analyzed using microarray. To verify the microarray data, the expression of miRNAs was evaluated by real-time PCR. Gene ontology (GO) and genes and genomics (KEGG) pathway enrichment of the predicted target genes of miRNAs were analyzed. The miRNA expression profiles of plasma samples from healthy and GDM women are distinct. We identified 93 differently expressed miRNAs. Compared with healthy pregnant women, 48 miRNAs including miR-574-5p and miR-3135b exhibited significantly lower expression in plasma samples from GDM patients. The expression of miR-574-5p was significantly correlated with levels of blood glucose and LDL-C; miR-3135b was significantly correlated with HDL-C. Some predicted common target genes of these two miRNAs are associated with the metabolism of glucose and lipids as well as the insulin signaling pathway. miR-574-5p and miR-3135b may serve as metabolic regulators of glucose and lipids for GDM.
Chiral propulsion: the method of effective boundary conditions

description: We propose to apply an "effective boundary condition" method to the problem of chiral propulsion. For the case of a rotating helix moving through a fluid at a low Reynolds number, the method amounts to replacing the original helix (in the limit of small pitch) by a cylinder, but with a special kind of partial slip boundary conditions replacing the non-slip boundary conditions on the original helix. These boundary conditions are constructed to reproduce far-field velocities of the original problem, and are defined by a few parameters (slipping lengths) that can be extracted from a problem in planar rather than cylindrical geometry. We derive the chiral propulsion coefficients for spirals, helicoids, helically modulated cylinders, and some of their generalizations using the introduced method. In the case of spirals, we compare our results with the ones derived by Lighthill and find a very good agreement. The proposed method is general and can be applied to any helical shape in the limit of a small pitch. We have established that for a broad class of helical surfaces the dependence of the chiral propulsion on the helical angle $θ$ is universal, $χ\sim \cosθ\sin 2θ$ with the maximal propulsion achieved at the universal angle $θ_m = \tan^{-1}(1/\sqrt{2})\approx 35.26^\circ$.

description: We present a simulation showing that super-Nyquist frequencies may have periodic amplitude and frequency modulations, even if actually stable, in time series sampled like the Kepler data. These modulations are caused by the barycentric time correction, which destroys the evenly spaced time measurements, making the Nyquist frequency variable over the spacecraft orbit around the Sun. These modulations can easily be identified in pulsating stars from Kepler's photometric data.

description: First-principles calculations based on spin-polarised density functional theory have been used here to investigate the structural, electronic and magnetic properties of tape-heme monolayer (THM) with gas molecules (H2O, N2, HCN, NH3, NO2 and SO2) adsorption. Our results suggest that H2O and NH3 are physisorbed on THM while N2, HCN, NO2 and SO2 are adsorbed on THM by chemisorption. The toxic HCN, NH3, NO2 and SO2 can be effectively captured by THM according to their adsorption energy (> 0.50 eV). The adsorption of NO2 (or SO2) can partly (or completely) decrease the spin moment of THM and induce the transition from the metallic property into half-metallic (or semiconductor) behaviour. The magnetism of the NO2 adsorption system is sensitive to tensile strain while that of the SO2 adsorption system is invariably non-spin polarised regardless of the compressive or tensile strain. The electronic structure of the NO2 and SO2 adsorption system can be effectively modulated by external biaxial strain. Our findings reveal that THM could effectively detect toxic NO2 and SO2 in an environment with high sensitivity and selectivity and reactivity, indicating that it possesses a potential application in the field of heme-based gas sensors.

We construct dynamical models based on detailed photoionization models of the emission-line gas, including the effects of internal dust, to apply to observations of large-scale outflows from these AGNs. We use Mrk 477 and Mrk 34 in order to test our models against recent HST STIS observations of [O III] emission-line kinematics since these AGNs possess more energetic outflows than found in Seyfert galaxies. We find that the outflows within 500 pc are consistent with radiative acceleration of dusty gas, however, the outflows in Mrk 34 are significantly more extended and may not be directly accelerated by radiation. We characterize the properties of X-ray winds found from the expansion of [O III]-emitting gas close to the black hole. We show that such winds possess the kinetic energy density to disturb [O III] gas at 1.8 kpc, and have sufficient energy to entrain the [O III] clouds at 1.2 kpc. Assuming that the X-ray wind possesses the same radial mass distribution as the [O III] gas, we find that the peak kinetic luminosity for this wind is 2% of Mrk 34's bolometric luminosity, which is in the 0.5% - 5% range required by some models for efficient feedback. Our work shows that, although the kinetic luminosity as measured from [O III]-emitting gas is frequently low, X-ray winds may provide more than one order of magnitude higher kinetic power.

description: We introduce a functorial construction $\mathsf{C}$ which takes unitary magmas $\mathcal{M}$ as input and produces operads. The obtained operads involve configurations of chords labeled by elements of $\mathcal{M}$, called $\mathcal{M}$-decorated cliques and generalizing usual configurations of chords. By considering combinatorial subfamilies of $\mathcal{M}$-decorated cliques defined, for instance, by limiting the maximal number of crossing diagonals or the maximal degree of the vertices, we obtain suboperads and quotients of $\mathsf{C} \mathcal{M}$. This leads to a new hierarchy of operads containing, among others, operads on noncrossing configurations, Motzkin configurations, forests, dissections of polygons, and involutions. Besides, the construction $\mathsf{C}$ leads to alternative definitions of the operads of simple and double multi-tildes, and of the gravity operad.

description: We investigate the emergence of isotropic linear elasticity in amorphous and polycrystalline solids, via extensive numerical simulations. We show that the elastic properties are correlated over a finite length scale $ξ_E$, so that the central limit theorem dictates the emergence of continuum linear isotropic elasticity on increasing the specimen size. The stiffness matrix of systems of finite size $L > ξ_E$ is obtained adding to that predicted by linear isotropic elasticity a random one of spectral norm $(L/ξ_E)^{-3/2}$, in three spatial dimensions. We further demonstrate that the elastic length scale corresponds to that of structural correlations, which in polycrystals reflect the typical size of the grain boundaries and length scales characterizing correlations in the stress field. We finally demonstrate that the elastic length scale affects the decay of the anisotropic long-ranged correlations of locally defined shear modulus and shear stress.

description: Studies using asteroseismic ages and rotation rates from star-spot rotation have indicated that standard age-rotation relations may break down roughly half-way through the main sequence lifetime, a phenomenon referred to as weakened magnetic braking. While rotation rates from spots can be difficult to determine for older, less active stars, rotational splitting of asteroseismic oscillation frequencies can provide rotation rates for both active and quiescent stars, and so can confirm whether this effect really takes place on the main sequence. We obtained asteroseismic rotation rates of 91 main sequence stars showing high signal-to-noise modes of oscillation. Using these new rotation rates, along with effective temperatures, metallicities and seismic masses and ages, we built a hierarchical Bayesian mixture model to determine whether the ensemble more closely agreed with a standard rotational evolution scenario, or one where weakened magnetic braking takes place. The weakened magnetic braking scenario was found to be 98.4% more likely for our stellar ensemble, adding to the growing body of evidence for this stage of stellar rotational evolution. This work represents the largest catalogue of seismic rotation on the main sequence to date, opening up possibilities for more detailed ensemble analysis of rotational evolution with Kepler.

Optimal Scheduling of Integrated Demand Response-Enabled Integrated Energy Systems with Uncertain Renewable Generations: A Stackelberg Game Approach

description: In order to balance the interests of integrated energy operator (IEO) and users, a novel Stackelberg game-based optimization framework is proposed for the optimal scheduling of integrated demand response (IDR)-enabled integrated energy systems with uncertain renewable generations, where the IEO acts as the leader who pursues the maximization of his profits by setting energy prices, while the users are the follower who adjusts energy consumption plans to minimize their energy costs. Taking into account the inherent uncertainty of renewable generations, the probabilistic spinning reserve is written in the form of a chance constraint; in addition, a district heating network model is built considering the characteristics of time delay and thermal attenuation by fully exploiting its potential, and the flexible thermal comfort requirements of users in IDR are considered by introducing a predicted mean vote (PMV) index. To solve the raised model, sequence operation theory is introduced to convert the chance constraint into its deterministic equivalent form, and thereby, the leader-follower Stackelberg game is tackled into a mixed-integer quadratic programming formulation through Karush-Kuhn-Tucker optimality conditions and is finally solved by the CPLEX optimizer. The results of two case studies demonstrate that the proposed Stackelberg game-based approach manages to achieve the Stackelberg equilibrium between IEO and users by the coordination of renewable generations and IDR. Furthermore, the study on a real integrated energy system in China verifies the applicability of the proposed approach for real-world applications.

description: Cable based mounting systems of solar modules offers several promising options of using existing
infrastructure installations to apply PV application on top. This concept of double use of land was successfully
applied to a 650kW Solar Wings PV plant two meters on top of a waste disposal site, or a 90kW PV plant eight
meters above an industrial outdoor storage facility or on top of a skilift in Switzerland. The analysis of the first three
years of operation of the 650kW one-axis tracking installation in Southern Germany proofed a tracking gain of 23.5%
of the irradiance relative to a standard fixed installation. Together with the measured excellent yearly AC
performance ratio of 0.9 the average annual yields to 1325kWh/kW was measured due to the perfect cooling of the
PV modules at their mounting position several meters above ground. New cable based PV installation on top of
Carports and other light weight low cost cable based PV installation are discussed.
Dielectrophoresis model for the colossal electroresistance of phase-separated manganites

description: We propose a dielectrophoresis model for phase-separated manganites. Without increase of the fraction of metallic phase, an insulator-metal transition occurs when a uniform electric field applied across the system exceeds a threshold value. Driven by the dielectrophoretic force, the metallic clusters reconfigure themselves into stripes along the direction of electric field, leading to the filamentous percolation. This process, which is time-dependent, irreversible and anisotropic, is a probable origin of the colossal electroresistance in manganites.

description: We propose a new approach for the solution of initial value problems for integrable evolution equations in the periodic setting based on the unified transform. Using the nonlinear Schrödinger equation as a model example, we show that the solution of the initial value problem on the circle can be expressed in terms of the solution of a Riemann-Hilbert problem whose formulation involves quantities which are defined in terms of the initial data alone. Our approach provides an effective solution of the problem on the circle which is conceptually analogous to the solution of the problem on the line via the inverse scattering transform.

description: Any n-qubit state with n independent perfect correlations is equivalent to a graph state. We present the optimal Bell inequalities for perfect correlations and maximal violation for all classes of graph states with n < 7 qubits. Twelve of them were previously unknown and four give the same violation as the Greenberger-Horne-Zeilinger state, although the corresponding states are more resistant to decoherence.

description: This paper presents the progress of ongoing efforts at SunPower Corporation to increase the module
efficiency in high volume production of E20 (20% efficiency) module platform. As we continue to ramp up the
volumes of this platform in production, progress is being made on increasing the control of materials quality, design
and process parameters that enabled increased average efficiency of module by 0.4% absolute over 18 months ,
resulting in a current average 20.5% module efficiency. This record performance is matched by high reliability of the
module as we are continuing our test to failure based on IEC 61215 standards and we do not see increased
degradation. SunPower continues to push the efficiency limits on both cell and module. Recently Generation 3
Maxeon™ cell was introduced to production. With the increased power from cell, we now have initial production
that show an average module efficiency > 21%.

description: One-way quantum computing allows any quantum algorithm to be implemented easily using just measurements. The difficult part is creating the universal resource, a cluster state, on which the measurements are made. We propose a radically new approach: a scalable method that uses a single, multimode optical parametric oscillator (OPO). The method is very efficient and generates a continuous-variable cluster state, universal for quantum computation, with quantum information encoded in the quadratures of the optical frequency comb of the OPO.
