description: To report 5- and 7-year outcomes after image-guided moderately accelerated hypofractionated proton therapy (AHPT) for prostate cancer. We reviewed the first 582 prostate cancer patients enrolled on prospective outcomes tracking trial and treated with double-scattered moderately AHPT between 2008 and 2015. 269 patients had low-risk (LR) and 313 had intermediate-risk (IR) disease, including 149 with favorable intermediate-risk (FIR) and 164 with unfavorable intermediate-risk (UIR) disease. LR patients received a median 70.0GyRBE (2.5GyRBE/fraction) and IR patients received a median of 72.5 GyRBE. Seventeen patients (UIR, n = 12) received androgen deprivation therapy (ADT) for a median of 6 months. Toxicities were graded per the CTCAE, v4.0, and patient-reported quality-of-life data were reviewed. Median follow-up was 8.0 years (0.9–12.2). The 5- and 7-year rates of freedom from biochemical progression (FFBP) overall and in the LR and IR subsets, respectively, were 96.8/95.2%, 98.8/98.8%, and 95.0/91.9%. For the FIR and UIR subsets, they were 97.2/95.2% and 93.1/88.8%. Actuarial 5- and 7-year rates of late CTCAE, v4.0, grade 2 gastrointestinal (GI), grade 3 GI, and grade 3 genitourinary (GU) toxicities were 9.9%/11.2%, 1.4/1.4% and 1.3/2.1%, respectively. No grade ≥4 GI or GU toxicities occurred. The mean (standard deviation, SD) IPSS and EPIC Composite bowel function and bother scores were 7 (SD = 5), 97 (SD = 7), and 94 (SD = 6), respectively at baseline, 7 (SD = 5), 92 (SD = 13), and 92 (SD = 9) at the 5-year follow-up, and 7 (SD = 5), 93 (SD = 12), and 92 (SD = 10) at the 7-year follow-up. Image-guided AHPT 5- and 7-year outcomes show high efficacy, minimal physician-assessed toxicity, and excellent patient-reported outcomes in this cohort.

description: Während für die Jahre 1995 bis 1998 für das Qualitäts- und Herkunftszeichen „Qualität aus Bayern“ bei Rindfleisch signifikante, positive Wohlfahrtseffekte und eine Mehrzahlungsbereitschaft beim Verbraucher ermittelt wurden, ergibt sich für die Zeit nach BSE aufgrund weitgehender Veränderungen verschiedener Einflussfaktoren eine neue Situation. Im Rahmen der vorliegenden Arbeit wird der Frage, ob Gütezeichen eine Bedeutung beim Kauf von Rindfleisch haben, mittels einer empirischen Konsumentenstudie nachgegangen. Im Fokus der Betrachtungen stehen die „Geprüfte Qualität-Bayern“ (als Nachfolgeprogramm der „Qualität aus Bayern“), die Bezeichnung „Bayerisches Rindfleisch“, welche als geschützte geographische Angabe (g.g.A.) gemäß der Verordnung (EG) 510/06 im März 2011 eingetragen wurde sowie das Zeichen „Qualität und Sicherheit“ (QS). Die Resultate zeigen, dass alle analysierten Labellings signifikante, jedoch deutlich unterschiedliche Effekte auf die Kaufbereitschaft ausüben. While for the time period 1995 to 1998 significant and positive welfare effects and a consumer willingness-to-pay could be measured for the origin and certification mark “Qualität aus Bayern” there is a new situation after the BSE crisis due to changes of several impact factors. In the framework of this paper we analyze if certification marks still have relevance when buying beef. For this purpose we conduct an empirical consumer study in Bavaria. At this we focus on the label “Geprüfte Qualität Bayern”, the denomination Bavarian Beef which is meanwhile registered as protected geographical indication (PGI) according to regulation (EC) 510/06 and the label “Qualität und Sicherheit” (QS). The results show significant but varying effects for all analyzed labellings.

description: Auf Grundlage der garantierten Einspeisevergütungen des Erneuerbaren-Energien-Gesetzes sind in den vergangenen Jahren vermehrt Biogasanlagen auf Basis landwirtschaftlichen Energiepflanzenanbaus errichtet worden. Der vorliegende Beitrag prüft, ob die gestiegene Biogaserzeugung landwirtschaftliche Pachtpreise erhöht. Dazu werden räumlich-ökonometrische Schätzungen einzelbetrieblicher Neupachtpreisdaten der Agrarstrukturerhebungen 2007 und 1999 vorgenommen. Die landwirtschaftliche Biogaserzeugung, gemessen als einzelbetrieblicher Anbauanteil von Energiepflanzen zur Biogaserzeugung, erhöht die Pachtpreise der 2005 und 2006 neu abgeschlossenen Pachtverträge für Acker- und Grünland nur in Westdeutschland signifikant. Die geschätzte Summe an zusätzlicher jährlicher Pachtzahlung, hervorgerufen durch die Biogaserzeugung, beträgt bei Hochrechnung auf die gesamte Pachtfläche Westdeutschlands – je nach Modellspezifikation – etwa 7 bis 9 Mio. €. Allerdings ist für nach 2006 abgeschlossene Pachtverträge eine höhere Überwälzung in Pachtpreise zu erwarten. Biogas production has received considerable attention in Germany. Especially during the last years many biogas plants have been built due to increased feed-in tariffs for electricity guaranteed by the German renewable energy law. We analyse whether the use of arable and pasture land to produce ‘feed’ for the biogas plants increases farmland rental rates. The analysis is based on farm-level data of newly contracted rental agreements in 2005 and 2006 collected by the national agricultural census. We apply a spatial econometric approach to estimate the determinants of rental rates which explicitly takes dependence among neighbouring rental rates into account. Agricultural biogas production, measured as the share of acreage cultivated with energy crops, increases the rental rates in Western Germany significantly, but not in Eastern Germany. The estimated annual sum of additional rental payments due to biogas production projected on the whole rented acreage in Western Germany amounts to approximately € 7 – 9 m. However, for rental agreements contracted after 2006 a higher impact on rental prices is expected.

description: Solvent loss due to evaporation in a drying drop can drive capillary flows and solute migration. The flow is controlled by the evaporation profile and the geometry of the drop. We predict the flow and solute migration near a sharp corner of the perimeter under the conditions of uniform evaporation. This extends the study of Ref. 6, which considered a singular evaporation profile, characteristic of a dry surrounding surface. We find the rate of the deposit growth along contact lines in early and intermediate time regimes. Compared to the dry-surface evaporation profile of Ref. 6, uniform evaporation yields more singular deposition in the early time regime, and nearly uniform deposition profile is obtained for a wide range of opening angles in the intermediate time regime. Uniform evaporation also shows a more pronounced contrast between acute opening angles and obtuse opening angles.

description: In diesem Artikel wird der Produktivitätsfortschritt in ökologisch wirtschaftenden Betrieben im Zeitraum 1999/2000 bis 2006/07 quantifiziert und der Produktivitätsentwicklung vergleichbarer konventioneller Betriebe gegenübergestellt. Die Messung des Produktionsfortschritts erfolgt anhand des Malmquist-Produktivitätsindex auf Basis einer stochastischen Frontier- Analyse. Die Datengrundlage bildet ein balanciertes Panel betriebswirtschaftlicher Jahresabschlüsse von je 151 ökologischen und konventionellen Landwirtschaftsbetrieben. Die konventionellen Vergleichsbetriebe wurden durch ein Matchingverfahren ermittelt. Es zeigt sich, dass das Produktivitätsniveau der ökologischen Futterbau- und Verbundbetriebe im Mittel niedriger ist als im konventionellen Landbau, die ökologischen Betriebe aber mit dem Produktivitätsfortschritt vergleichbarer konventioneller Betriebe mithalten können. Die ökologisch wirtschaftenden Ackerbaubetriebe weisen zum Beginn des Analysezeitraums einen Produktivitätsvorsprung vor den entsprechenden Vergleichsbetrieben auf, den sie über den achtjährigen Beobachtungszeitraum jedoch nicht aufrechterhalten können. Die Anwendung des Malmquist- Index verdeutlicht, dass diese Entwicklung nicht auf mangelnden technischen Fortschritt zurückzuführen ist. Vielmehr sind Probleme im Bereich der technischen Effizienz und in der Ausnutzung von Skaleneffekten zu erkennen. This article sets out to investigate the development of total factor productivity in organic and conventional agriculture in the period from 1999/2000 to 2006/07. Productivity development is assessed with the use of Malmquist Indices based on Stochastic Frontier Analysis. The analysis is based on a balanced panel of farm records of 151 organic and conventional farms, respectively. A matching procedure is applied to identify for each organic farm a conventional counterpart with similar structural features. The study reveals a similar development of productivity in organic grazing livestock and mixed farms, but the productivity level is still lower compared to their conventional counterparts. Only organic arable farms had started off with a higher level of productivity in 1999/2000 but they were not able to maintain their advantage over their conventional counterparts. The Malmquist analysis highlights that these changes cannot be attributed to low rates of technical progress. Lack of technical and scale efficiency are rather to be seen as the key drivers of the slowed productivity development in organic agriculture.

description: Die Bereitstellung und verbrauchergerechte Aufbereitung von Informationen stellt eine Möglichkeit dar, Konsumenten darin zu unterstützen, Gesundheitsaspekte vermehrt in das Kauf- und Essverhalten zu integrieren. In der Verhaltensökonomik gelten Framing-Effekte als wichtige Bestimmungsfaktoren für die Wahrnehmung von Informationen. Im Rahmen des vorliegenden Beitrags werden Framing-Effekte am Beispiel von Ernährungsinformationen über Folsäure mit Hilfe eines Experiments untersucht. Die Ergebnisse zeigen, dass der Frame einen, wenn auch nur geringen, Einfluss auf die Wahrnehmung, das Informationsbedürfnis und den Entscheidungsprozess ausübt. Insgesamt verursacht der negative Frame, wie erwartet, stärkere Effekte als der positive. One way to support consumers in integrating health aspects into their purchase and eating behaviour is to make information available to consumers in a comprehensible manner. In behavioural economics framing effects are acknowledged as important factors influencing perception of information. In this paper framing effects are analysed by means of an experiment using the example of information about folic acid. The results give evidence that framing influences consumers’ perception, the need for information and decision process even though the effect is small. Overall, a negative frame results in a stronger effect than a positive one.

description: The objective of the TeRRItoria project is to experiment with ‘territorial RRI’: the adoption of Re-sponsible Research and Innovation principles in regional and local governance and R&I systems via Transformative Experiments in five selected European territories:
 - Central Macedonia (Greece): Co-creating a Gender Equality Plan with and for the R&I sector
 - Emilia-Romagna (Italy): Insert RRI approaches and methodologies into the regional Smart Specialization Strategy (S3) 2021-2027 together with stakeholders. Develop a methodology for their continued involvement in all phases of S3
 - Municipality of Gabrovo (Bulgaria): Strengthen collaboration between stakeholders by in-volving them in conceptualizing and developing the regional Smart Specialization Strategy 2021-2027. Support the adoption of RRI principles in the R&I sector with a Public Engage-ment Plan.
 - North-East Romania (Romania): Adapt the Entrepreneurial Discovery Process to the local level in two mountainous micro-territories, enabling local stakeholder to express and priori-tize innovation needs. Establish collaboration between local areas and researchers via a bro-kerage platform.
 - Trøndelag (Norway): fostering meaningful exchanges between the urban university NTNU and rural regions via internships, trainee positions, and the networks of researchers.
 The report at hand presents the results of the summative evaluation of these five experiments. The focus is, to what extent the local teams have reached the goals they have set for their experiments, whether they have observed changes in the territory and/or within their own organizations, and an assessment of the long-term sustainability of the initiatives started during the project. The evalua-tion draws on the practical participatory evaluation (PPE) model, which emphasizes ‘interactive data production, knowledge co-construction, local context of action and instrumental use’ (Smits and Champagne 2008, p. 427) and thus rely on the observation and experiences of the local teams cap-tured via document analysis and interviews.

description: We investigate many-body phase diagrams of atomic boson-fermion mixtures loaded in the two-dimensional optical lattice. Bosons mediate an attractive, finite-range interaction between fermions, leading to fermion pairing phases of different orbital symmetries. Specifically, we show that by properly tuning atomic and lattice parameters it is possible to create superfluids with $s$-, $p$-, and d-wave pairing symmetry as well as spin and charge density wave phases. These phases and their stability are analyzed within the mean-field approximation for systems of $^{40}$K-$^{87}$Rb and $^{40}$K-$^{23}$Na mixtures. For the experimentally accessible regime of parameters, superfluids with unconventional fermion pairing have transition temperature around a percent of the Fermi energy.

description: Computational imaging is increasingly vital for a broad spectrum of applications, ranging from biological to material sciences. This includes applications where the object is known and sufficiently sparse, allowing it to be described with a reduced number of parameters. When no explicit parameterization is available, a deep generative model can be trained to represent an object in a low-dimensional latent space. In this paper, we harness this dimensionality reduction capability of autoencoders to search for the object solution within the latent space rather than the object space. We demonstrate a novel approach to ptychographic image reconstruction by integrating a deep generative model obtained from a pre-trained autoencoder within an Automatic Differentiation Ptychography (ADP) framework. This approach enables the retrieval of objects from highly ill-posed diffraction patterns, offering an effective method for noise-robust latent vector reconstruction in ptychography. Moreover, the mapping into a low-dimensional latent space allows us to visualize the optimization landscape, which provides insight into the convexity and convergence behavior of the inverse problem. With this work, we aim to facilitate new applications for sparse computational imaging such as when low radiation doses or rapid reconstructions are essential.

description: The aim of the article was to answer the question asked in its title, if the crisis was a threat to the companies noted in the WIG Food Industry index. An analysis of their economic and financial results has showed that Agriculture and Food Industry companies had taken advantage of the favourable circumstances accompanying the Polish accession to the European Union and then coped well with the difficult period of crisis. The subject of analysis was the impact of this economic situation on functioning of WIG Food Industry companies in recent years. It was found that Food Industry companies functioned well during the global financial and economic crisis. However, the WIG Food Industry index has always depended on the global economic situation and the general stock exchange climate. / Synopsis. Celem napisania artykułu była odpowiedź na pytanie postawione w jego tytule, czy kryzys zagrażał spółkom włączonym do indeksu WIG Spożywczy. Analiza wyników ekonomiczno-finansowych wykazała, że przedsiębiorstwa przemysłu rolno-spożywczego wykorzystały sprzyjające warunki akcesji Polski do Unii Europejskiej, a następnie dobrze poradziły sobie z trudnym okresem kryzysu. Analizie poddano oddziaływanie koniunktury gospodarczej na działalność przedsiębiorstw należących do indeksu WIG Spożywczy w okresie ostatnich lat. Stwierdzono, że spółki spożywcze dobrze funkcjonowały w okresie światowego kryzysu finansowego i gospodarczego, jednak indeks WIG Spożywczy zawsze był i jest zależny od ogólnoświatowej koniunktury gospodarczej i panującego ogólnego klimatu giełdowego.

description: The economic theory links the growth of production factors remuneration with the productivity improvement. In the case of contemporary European agriculture, among the most important income creators are money transfers, namely direct payments. These transfers are part of the agricultural and rural policy directed at fulfillment of societal goals. The research investigates relations between changes of agricultural productivity and the share of direct payments in incomes from agriculture in the EU member states. The level of direct support and the productivity development were analyzed in the context of programming the agricultural growth policy. / Synopsis.

description: Multichannel Analysis of Surface Waves (MASW) is a technique frequently used in geotechnical engineering and engineering geophysics to infer layered models of seismic shear wave velocities in the top tens to hundreds of meters of the subsurface. We aim to accelerate MASW calculations by capitalizing on modern computer hardware available in the workstations of most engineers: multiple cores and graphics processing units (GPUs). We propose new parallel and GPU accelerated algorithms for evaluating MASW data, and provide software implementations in C using Message Passing Interface (MPI) and CUDA. These algorithms take advantage of sparsity that arises in the problem, and the work balance between processes considers typical data trends. We compare our methods to an existing open source Matlab MASW tool. Our serial C implementation achieves a 2x speedup over the Matlab software, and we continue to see improvements by parallelizing the problem with MPI. We see nearly perfect strong and weak scaling for uniform data, and improve strong scaling for realistic data by repartitioning the problem to process mapping. By utilizing GPUs available on most modern workstations, we observe an additional 1.3x speedup over the serial C implementation on the first use of the method. We typically repeatedly evaluate theoretical dispersion curves as part of an optimization procedure, and on the GPU the kernel can be cached for faster reuse on later runs. We observe a 3.2x speedup on the cached GPU runs compared to the serial C runs. This work is the first open-source parallel or GPU-accelerated software tool for MASW imaging, and should enable geotechnical engineers to fully utilize all computer hardware at their disposal.

description: Imaging data from the Sloan Digital Sky Survey is used to measure the empirical size-richness relation for a large sample of galaxy clusters. Using population subtraction methods, we determine the radius at which the cluster galaxy number density is 200/Omega_m times the mean galaxy density, without assuming a model for the radial distribution of galaxies in clusters. If these galaxies are unbiased on Mpc scales, this galaxy-density-based R_200 reflects the characteristic radii of clusters. We measure the scaling of this characteristic radius with richness over an order of magnitude in cluster richness, from rich clusters to poor groups. We use this information to examine the radial profiles of galaxies in clusters as a function of cluster richness, finding that the concentration of the galaxy distribution decreases with richness and is systematically lower than the concentrations measured for dark matter profiles in N-body simulations. Using these scaled radii, we investigate the behavior of the cluster luminosity function, and find that it is well matched by a Schechter function for galaxies brighter than M_r = -18 only after the central galaxy has been removed. We find that the luminosity function varies with richness and with distance from the cluster center, underscoring the importance of using an aperture that scales with cluster mass to compare physically equivalent regions of these different systems. We note that the lowest richness systems in our catalog have properties consistent with those expected of the earliest-forming halos; our cluster-finding algorithm, in addition to reliably finding clusters, may be efficient at finding fossil groups.

description: The detection of transits is an efficient technique to uncover faint companions around stars. The full characterisation of the companions (M-type stars, brown dwarfs or exoplanets) requires high-resolution spectroscopy to measure properly masses and radii. With the advent of massive variability surveys over wide fields, the large number of possible candidates makes such a full characterisation impractical for all of them. We explore here a fast technique to pre-select the most promising candidates using either near-IR photometry or low resolution spectroscopy. We develop a new method based on the well-calibrated surface brightness relation along with the correlation between mass and luminosity for main sequence stars, so that not only giant stars can be excluded but also accurate effective temperatures and radii can be measured. The main source of uncertainty arises from the unknown dispersion of extinction at a given distance. We apply this technique to our observations of a sample of 34 stars extracted from the 62 low-depth transits identified by OGLE during their survey of some 10e5 stars stars in the Carina fields of the Galactic disc. We infer that at least 78% of the companions of the stars which are well characterised in this sample are not exoplanets. Stars OGLE-TR-105, OGLE-TR-109 and OGLE-TR-111 are the likeliest to host exoplanets and deserve high-resolution follow-up studies. OGLE-TR-111 was very recently confirmed as an exoplanet with M_planet = 0.53 +- 0.1 M_Jup (Pont et al. 2004), confirming the efficiency of our method in pre-selecting reliable planetary transit candidates.

description: We propose and study an active cooling mechanism for the nanomechanical resonator (NAMR) based on periodical coupling to a Cooper pair box (CPB), which is implemented by a designed series of magnetic flux pluses threading through the CPB. When the initial phonon number of the NAMR is not too large, this cooling protocol is efficient in decreasing the phonon number by two to three orders of magnitude. Our proposal is theoretically universal in cooling various boson systems of single mode. It can be specifically generalized to prepare the nonclassical state of the NAMR.

description: Flexible controlled heat pumps in combination with thermal storages are expected to play a key role in near future energy systems exhibiting larger shares of renewable energies. In such systems, surplus energy from windfarms or PV will be stored and used later at times of higher energy demands and prices. For energy consumers, this will lead to cost savings while supporting the further expansion of renewable energies. In this work, these relevant cost savings are quantified using a linear programming approach. Furthermore, is this approach applied to different energy users, electricity tariffs and heat demands. As a result, it is shown that the potential variable cost savings with respect to heat users and electricity tariffs vary from 0.9 to 2.7 €/MWh, and the potential load shift from 3 to 6 hours.

description: Given function values on a domain $D_0$, possibly with noise, we examine the possibility of extending the function to a larger domain $D$, $D_0\subset D$. In addition to smoothness at the boundary of $D_0$, the extension on $D\setminus D_0$ should also inherit behavioral trends of the function on $D_0$, such as growth and decay or even oscillations. The approach chosen here is based upon the framework of linear models, univariate or bivariate, with constant or varying coefficients.

description: We consider a static, spherically symmetric space-time with an electric field arising from a quadratic metric-affine extension of General Relativity. Such a space-time is free of singularities in the centre of the black holes, while at large distances it quickly boils down to the usual Reissner-Nordström solution. We probe this space-time metric, which is uniquely characterized by two length scales, $r_q$ and $\ell$, using the astrometric and spectroscopic measurements of the orbital motion of the S2 star around the Galactic Center. Our analysis constrains $r_q$ to be below $2.7M$ for values $\ell<120 AU$, strongly favouring a central object that resembles a Schwarzschild black hole.

We give a number of explicit examples of such models. Using an idea of quasi-invariance of a state, we show how one can construct unitary representations of various groups. Moreover in models with locally conserved quantities associated to an infinite lattice we show that there is no spectral gap and the corresponding dissipative dynamics decay to equilibrium polynomially in time.

description: We present preliminary measurements of branching fractions and CP-asymmetry parameters in two- and three-body charmless hadronic B decays. The available data sample consists of 227 million Upsilon(4S) B decays collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We establish the observation of the decays B --> pi0 pi0 and B0 --> K0K0bar and constrain the CKM angle alpha with a full SU(2) isospin analysis in the B --> pi pi system and with a B0 --> pi+ pi- pi0 time-dependent Dalitz plot analysis.

description: The main goal of the EU food safety policy is to ensure human life protection on the highest possible level. In the present stage of Polish economy development, the major problem is an improvement of competitiveness. After Poland’s accession to the European Union, entrepreneurs had to decide ways of their further economic activities. Although the integration brought great opportunities, there were also numerous problems and fears connected with the fact. In this connection the issue of competitiveness, especially within agribusiness enterprises, is an extremely important aspect of Polish economic development. However, there are many economic as well as non-economic factors deciding on the ability of competitiveness enhancement in particular branches of economy. Moreover, methods that have been based on cost and price relations are no longer effective enough, so that entrepreneurs have to search for more successful methods and tools to gain long-lasting advantages over their market competitors. Both theory and practise prove that nowadays the widely understood quality supported by implementation of certified quality management systems’ rules can be such a factor. / Synopsis. Główny cel polityki UE w zakresie bezpieczeństwa żywności to zapewnienie jak najwyższego stopnia ochrony zdrowia konsumenta. Na obecnym etapie rozwoju polskiej gospodarki głównym jej problemem jest poprawa konkurencyjności. Wejście naszego kraju do Unii Europejskiej, postawiło wiele przedsiębiorstw przed koniecznością wyboru drogi ich dalszego funkcjonowania. Wraz z wielkimi nadziejami, jakie niosła integracja pojawiło się również wiele problemów i obaw związanych z tym faktem. Kwestia konkurencyjności szczególnie wśród przedsiębiorstw agrobiznesu jest niezmiernie ważnym aspektem rozwoju polskiej gospodarki. O zdolności do poprawy konkurencyjności danej dziedziny decyduje wiele czynników, zarówno o charakterze ekonomicznym jak i pozaekonomicznym. Teoria i praktyka dowodzą, że w obecnej dobie jednym z czynników może być szeroko pojęta jakość, poparta wdrażaniem systemów zarządzania jakością.

description: To enable highly automated vehicles where the driver is no longer a safety backup, the vehicle must deal with various Functional Insufficiencies (FIs). Thus-far, there is no widely accepted functional architecture that maximizes the availability of autonomy and ensures safety in complex vehicle operational design domains. In this paper, we present a survey of existing methods that strive to prevent or handle FIs. We observe that current design-time methods of preventing FIs lack completeness guarantees. Complementary solutions for on-line handling cannot suitably increase safety without seriously impacting availability of journey continuing autonomous functionality. To fill this gap, we propose the Safety Shell, a scalable multi-channel architecture and arbitration design, built upon preexisting functional safety redundant channel architectures. We compare this novel approach to existing architectures using numerical case studies. The results show that the Safety Shell architecture allows the automated vehicle to be as safe or safer compared to alternatives, while simultaneously improving availability of vehicle autonomy, thereby increasing the possible coverage of on-line functional insufficiency handling.

description: The objective of this work is to analyse the current status of the Chinese renewable energy program (wind power and solar PV) and outline its future prospects. In this context, one particular endeavour of this work has been to discuss China not only at the macro level (i.e. China as a single unit), but also to discuss the different financial and technical realities of the wind and solar PV sectors at the provincial level. This work will use a combination of quantitative and qualitative data for the analysis of the country’s renewable energy program. The quantitative analysis will cover areas such as power demand/supply dynamics, electricity capacity and production, Feed-in Tariff costs, and other factors regarding the economics of renewable energy. The qualitative analysis mainly covers the areas related to environmental and energy policies, including the latest reforms of the power sector. This work has been able to identify the unique features of the Chinese renewable energy program and further research should be undertaken in order improve the understanding of renewable energy development in China and the complexity of its national and provincial system for developing wind and solar PV. In the last ten years, China has made major progress in the deployment of wind power and solar PV capacity and it will likely meet or surpass its 2020 targets for these power sources. There are, however, several challenges ahead for the deployment of these electricity sources. China is not only planning to increase renewable energy capacity to its electricity mix by 2020 and beyond, but it is also expanding the capacity of nuclear, hydro, natural gas, and – to a lesser extend – coal. As China’s is experiencing power overcapacity, the constant expansion of electricity production does not seem to be the best way forwards for the country. The government is, nevertheless, trying to address the overcapacity issue and other related challenges and has introduced several pieces of legislation to reform the Chinese electricity market. Many of these reforms have just started to be implemented or will start soon. It is therefore too early to predict how they will affect the electricity market in general and the wind power and solar PV markets in particular. What is clear though is that the Chinese government has taken the policy decision to move away from coal and deploy sources with lower CO2 emissions.
Supersymmetry, Naturalness and the Landscape

description: We argue that the study of the statistics of the landscape of string vacua provides the first potentially predictive -- and also falsifiable -- framework for string theory. The question of whether the theory does or does not predict low energy supersymmetry breaking may well be the most accessible to analysis. We argue that low energy -- possibly very low energy -- supersymmetry breaking is likely to emerge, and enumerate questions which must be answered in order to make a definitive prediction.

Vortex nucleation in a superfluid
Creators: name: Marchand, Dominic
Publisher: name: University of British Columbia
Year: 2010

description: Superfluids have very peculiar rotational properties as the Hess-Fairbank experiment spectacularly demonstrates. In this experiment, a rotating vessel filled with helium is cooled down past the critical temperature. Remarkably, as the liquid becomes superfluid, it gradually stops its rotation. This expulsion of vorticity, analogous to the Meissner effect, provides a fundamental experimental definition of superfluidity. As a consequence, superfluids not only posses quasiparticles like phonons, but also quantized vortex excitations. This thesis examines the creation mechanism of vortices, or nucleation, in the low temperature limit. At these temperatures, thermal activation of vortices is ruled out and nucleation must be a tunneling effect. Unfortunately, there is no theory to describe this nucleation process. Vortex nucleation is believed to more likely occur in the vicinity of irregularities of the vessel. We therefore consider a few simple, yet experimentally realistic, two-dimensional configurations to calculate nucleation rates. Close to zero temperature and within a certain approximation, the superfluid is inviscid and incompressible such that it can naturally be treated as an ideal two-dimensional fluid flow. Calculating the energy of static vortex configurations can then be done with standard hydrodynamics. The kinetic energy of the flow as a function of the position of the vortex then describes a potential barrier for vortex nucleation. Under rotation, the vortex-free state becomes metastable and can decay to a state with one or more vortices. In this thesis, we carry out a semiclassical calculation of the nucleation rate exponent. We use the WKB method along the path of least action created by the presence of a bump or wedge. This work is but a first approximation as fluctuations around this path can be added as well. The main purpose has been to lay down the groundwork required to include the dissipative effect of the coupling to phonons, which is paramount to an accurate description of the phenomenon. This effect could then be included using the Caldeira-Leggett dissipative tunneling effect [4].

description: In the spirit of some earlier work on the construction of vector coherent states over matrix domains, we compute here such states associated to some physical Hamiltonians. In particular, we construct vector coherent states of the Gazeau-Klauder type. As a related problem, we also suggest a way to handle degeneracies in the Hamiltonian for building coherent states. Specific physical Hamiltonians studied include a single photon mode interacting with a pair of fermions, a Hamiltonian involving a single boson and a single fermion, a charged particle in a three dimensional harmonic force field and the case of a two-dimensional electron placed in a constant magnetic field, orthogonal to the plane which contains the electron. In this last example, an interesting modular structure emerges for two underlying von Neumann algebras, related to opposite directions of the magnetic field. This leads to the existence of coherent states built out of KMS states for the system.

description: In continuation of our previous study [Phys. Rev. D 99 (2019) 4, 044012], we investigate the motion of charged particles in the $γ$-metric. We provide some examples of curled trajectories in the equatorial plane and escape trajectories outside the equatorial plane. Finally, we consider harmonic oscillations due to small displacements from stable circular orbits on the equatorial plane and compute the epicyclic frequencies for different values of deformation parameter and magnetic field.
