description: We show, using ab initio total energy density functional theory, that the so-called Wigner defects, an interstitial carbon atom right besides a vacancy, which are present in irradiated graphite can also exist in bundles of carbon nanotubes. Due to the geometrical structure of a nanotube, however, this defect has a rather low formation energy, lower than the vacancy itself, suggesting that it may be one of the most important defects that are created after electron or ion irradiation. Moreover, they form a strong link between the nanotubes in bundles, increasing their shear modulus by a sizeable amount, clearly indicating its importance for the mechanical properties of nanotube bundles.

description: The radio emission during 201 X-ray selected solar flares was surveyed from 100 MHz to 4 GHz with the Phoenix-2 spectrometer of ETH Zurich. The selection includes all RHESSI flares larger than C5.0 jointly observed from launch until June 30, 2003. Detailed association rates of radio emission during X-ray flares are reported. In the decimeter wavelength range, type III bursts and the genuinely decimetric emissions (pulsations, continua, and narrowband spikes) were found equally frequently. Both occur predominantly in the peak phase of hard X-ray (HXR) emission, but are less in tune with HXRs than the high-frequency continuum exceeding 4 GHz, attributed to gyrosynchrotron radiation. In 10% of the HXR flares, an intense radiation of the above genuine decimetric types followed in the decay phase or later. Classic meter-wave type III bursts are associated in 33% of all HXR flares, but only in 4% they are the exclusive radio emission. Noise storms were the only radio emission in 5% of the HXR flares, some of them with extended duration. Despite the spatial association (same active region), the noise storm variations are found to be only loosely correlated in time with the X-ray flux. In a surprising 17% of the HXR flares, no coherent radio emission was found in the extremely broad band surveyed. The association but loose correlation between HXR and coherent radio emission is interpreted by multiple reconnection sites connected by common field lines.

The effect of lignosulfonates on the floatability of molybdenite and chalcopyrite
Creators: name: Ansari, Anita
Publisher: name: University of British Columbia
Year: 2010

description: The applicability of six lignosulfonates as selective depressants in chalcopyritemolybdenite separation was assessed by means of modified Hallimond tube flotation tests, supplemented by adsorption studies to determine the magnitude of lignosulfonatemineral interactions. Flotation and adsorption tests were performed as a function of pH using different pH modifiers, i.e. lime, potassium hydroxide (KOH) and soda ash. Size exclusion chromatograms (SEC) were generated to determine which molecular weight fractions of the lignosulfonates were actually adsorbing onto the surfaces of the minerals. The depression of chalcopyrite flotation by lignosulfonates was found to be related to the presence of physically adsorbed xanthate and the availability of metallic sites on the mineral surface. Once the physically adsorbed xanthate was removed from the surface, the depression of the mineral was possible only when lignosulfonates adsorbed onto the mineral. The adsorption process was enhanced by the presence of positively charged metallic sites on the mineral surface. The activating role of calcium ions introduced by lime for lignosulfonate adsorption was demonstrated. The depression of molybdenite flotation was a function of pH. Good flotation of molybdenite was observed only under neutral / weakly acidic pH values, and the addition of all lignosulfonates resulted in the complete depression of molybdenite flotation. As in the case of chalcopyrite, pH adjustments using KOH and soda ash decreased the adsorption of lignosulfonates, which strongly suggests that the lignosulfonate adsorption process was controlled by electrostatic repulsion between the anionic polyelectrolytes and the negatively charged mineral surface. When lime was used as a pH modifier, the adsorption density dramatically increased due to the presence of calcium species in solution. The SEC data indicated that higher molecular weight fractions of lignosulfonates preferentially interact with mineral surfaces. Overall, the results suggest that it is possible to selectively float chalcopyrite from molybdenite by depressing molybdenite. This can be achieved over a wide pH range provided that a pH modifier other than lime is used for pH control. It is suggested that this process option be used in a cleaner flotation stage where pulp dilution and the use of flotation columns could greatly enhance the selectivity of the process.

Subjects: subject: Steinschüttdämme

description: Aufgrund der möglichen Komplexität hinsichtlich der Geometrie, der geologischen Verhältnisse etc. stößt man teilweise bei der Anwendung händischer Berechnungsmethoden für die Bestimmung von Setzungen und Verformungen bei Steinschüttdämmen, schnell an Grenzen. Sind Inhomogenitäten im Bereich des Dammes zu berücksichtigen (zB. Einbauten), ist eine Berechnung mit Hilfe der Finite Elemente Methode zielführend. Im Zuge der Planung eines Speicherbeckens ist als Abschlussdamm ein zirka 40 m hoher Steinschüttdamm mit einer Asphaltoberflächendichtung (AFRD) zu planen bzw. zu berechnen. Diese Diplomarbeit befasst sich unter anderem mit den zugehörigen Standsicherheits- und Verformungsberechnungen. Einleitend werden die Grundlagen und Theorien des numerischen Berechnungsverfahrens erläutert und weiters die detaillierte Analyse und Auswertung der Berechnungsergebnisse aus den angewendeten FE-Programm GeoStudio 2007. Aufgrund der ermittelten Kräfte und Verformungen aus der Dammstatik wurde weiters ein Stahlbetondurchlassbauwerk (Kollektor) mittels des FE-Programm Infograph modelliert und statisch dimensioniert. Diese Diplomarbeit setzt sich weiters mit Stoffgesetzen auseinander, welche für die FE-Berechnung die Grundlage bilden. Des Weiteren werden die für Steinschüttmaterial spezifischen physikalischen Hintergründe analysiert und es wird versucht, einen Überblick über den vorhandenen Wissensstand zu vermitteln.
description: Due to the complexities in terms of geometry and geological conditions, conventional methods of computation quickly reach their limits. If other influences are present (e.g. installations and other inhomogeneities), a calculation with finite element programs is almost inevitable. In the course of the planning of a storage basin, a dam of about 40 m height (AFRD) is to be designed or calculated as the final embankment. Among other things, this master thesis deals with the related stability and deformation calculations. The basics and theories of the numerical calculations are explained, as well as the detailed analysis and evaluation of the calculation results from the FE program GeoStudio 2007. Due to the determined forces and deformations from the dam static calculation, a collector was modeled and designed statically in the FE program Infograph. This thesis considers also the material laws, which are optimized for the calculation of granular materials. The physical background of the rockfill material is also explained and an overview of the existing knowledge is given.

description: A new radio spectrometer, CALLISTO, is presented. It is a dual-channel frequency-agile receiver based on commercially available consumer electronics. Its major characteristic is the low price for hardware and software, and the short assembly time, both two or more orders of magnitude below existing spectrometers. The instrument is sensitive at the physical limit and extremely stable. The total bandwidth is 825 MHz, and the width of individual channels is 300 kHz. A total of 1000 measurements can be made per second. The spectrometer is well suited for solar low-frequency radio observations pertinent to space weather research. Five instruments of the type were constructed until now and put into operation at several sites, including Bleien (Zurich) and NRAO (USA). First results in the 45 - 870 MHz range are presented. Some of them were recorded in a preliminary setup during the time of high solar activity in October and November 2003.

description: In rural areas, many municipalities still do not have bank branches and credit cooperatives emerge as alternative institutions in providing credit, with distinct characteristics of banks, given their importance for local development. This study seeks to measure the impact of the implementation of supportive rural credit cooperatives in Brazilian municipalities on per capita GDP of agriculture (value added) using two quasi-experimental methods to provide robustness to the findings on the impact. It was verified a positive causal relationship, using differencesin- differences with matching by propensity score, indicating an average impact of the presence of supportive rural credit cooperatives on per capita agricultural GDP in 2010 of R$ 987,66, significant at 5%. Positive coefficients for the treatment variable were also observed in OLS regressions weighted by propensity scores, with the per capita GDP of agriculture roughly 20% higher for municipalities that created supportive rural credit cooperatives between 2008 and 2009. These results show the importance of creating supportive rural credit cooperatives in rural areas of Brazilian municipalities, especially in those that do not have them yet, since the role of these cooperatives is being played in order to contribute to the local growth.

description: Given a finite set $A$ and a group homomorphism $ϕ: H \to G$, a $ϕ$-cellular automaton is a function $\mathcal{T} : A^G \to A^H$ that is continuous with respect to the prodiscrete topologies and $ϕ$-equivariant in the sense that $h \cdot \mathcal{T}(x) = \mathcal{T}( ϕ(h) \cdot x)$, for all $x \in A^G, h \in H$, where $\cdot$ denotes the shift actions of $G$ and $H$ on $A^G$ and $A^H$, respectively. When $G=H$ and $ϕ= \text{id}$, the definition of $\text{id}$-cellular automata coincides with the classical definition of cellular automata. The purpose of this paper is to expand the theory of $ϕ$-cellular automata by focusing on the differences and similarities with their classical counterparts. After discussing some basic results, we introduce the following definition: a $ϕ$-cellular automaton $\mathcal{T} : A^G \to A^H$ has the unique homomorphism property (UHP) if $\mathcal{T}$ is not $ψ$-equivariant for any group homomorphism $ψ: H \to G$, $ψ\neq ϕ$. We show that if the difference set $Δ(ϕ, ψ)$ is infinite, then $\mathcal{T}$ is not $ψ$-equivariant; it follows that when $G$ is torsion-free abelian, every non-constant $\mathcal{T}$ has the UHP. Furthermore, inspired by the theory of classical cellular automata, we study $ϕ$-cellular automata over quotient groups, as well as their restriction and induction to subgroups and supergroups, respectively.

Open STM: A low-cost scanning tunneling microscope with a fast approach method
Creators: name: Ma, Weilin
Publisher: name: arXiv

Subjects: subject: Instrumentation and Detectors (physics.ins-det)
subject: FOS: Physical sciences

description: In this paper, we have designed a low-cost scanning tunneling microscope (STM) priced at 300 USD or 2000 CNY. This microscope is suitable for educational purposes and low-demand research imaging at the nanometer level. This microscope's motion components and scanner are controlled using piezoelectric materials, avoiding the thermal drift associated with traditional motor control. Our tip approach algorithm, which considers the capacitance and friction characteristics during piezoelectric slider movement, has reduced the time required for sample loading to establish tunneling current to approximately 1 minute. The dimensions of the microscope body are 45x45x31.5mm(WxLxH), and the control voltage does not exceed 15V, ensuring the safety of operators with limited experience. In the performance verification, we performed a scanning tunneling scan on a Highly Oriented Pyrolytic Graphite(HOPG) sample with bias voltages of 50mV and 60mV, resulting in clear observations of the atomic features of HOPG in the STM pattern.

description: In favor of a pesticide-free farming and against genetically modified seeds that do not fall into line to its production system, farmers in the semiarid of Paraíba state have prepared Community Seed Banks (BSC), which are part of a network called Seeds of Passion. This network is based on ideals of agroecology, agricultural practice alternative and sustainable ecological principles. The farmers who participate of this network constantly advocate a peasant identity and traditional, in opposition to modernization and capitalism. Therefore, thanks to the repetition of the need to effect the rescue of farmers tradition, we have as central object to reflect about the speech of tradition rescue propagated by agroecological farmers, by technicians who work with them and by those who write about this reality, seeking to understand, through an analysis of papers that deal with the experiences of the Seeds of Passion, what are the conditions of existence of the invention of this tradition and what is the purpose of promoting such redemption in a modern historical context. Finally, this tradition is not opposed to modernity and science, but it would be a way of developing and implementing distinct knowledge of the dominant standard of rationality.

description: This report presents possible loopholes in heavy $Z^\prime$ searches which are concentrated around high mass resonances. We present a scenario where massive neutral vector boson $Z^\prime$, predicted by $E_6$-inspired $U(1)^\prime$ models, can become leptophobic due to kinetic mixing between $Z-Z^\prime$. Such a scenario can avoid high-mass dilepton resonance searches. Furthermore, we propose a channel through supersymmetric cascade decays to observe leptophobic $Z^\prime$. We show that it is possible to reach up to $8σ$ at $\sqrt{s} = 14$ TeV and 3 ab$^{-1}$ integrated luminosity. This report follows the steps of the work that has been conducted in ref. [arXiv:1711.06302].

description: The emerging paradigm of interconnected microgrids advocates energy trading or sharing among multiple microgrids. It helps make full use of the temporal availability of energy and diversity in operational costs when meeting various energy loads. However, energy trading might not completely absorb excess renewable energy. A multi-energy management framework including fuel cell vehicles, energy storage, combined heat and power system, and renewable energy is proposed, and the characteristics and scheduling arrangements of fuel cell vehicles are considered to further improve the local absorption of the renewable energy and enhance the economic benefits of microgrids. While intensive research has been conducted on energy scheduling and trading problem, a fundamental question still remains unanswered on microgrid economics. Namely, due to multi-energy coupling, stochastic renewable energy generation and demands, when and how a microgrid should schedule and trade energy with others, which maximizes its long-term benefit. This paper designs a joint energy scheduling and trading algorithm based on Lyapunov optimization and a double-auction mechanism. Its purpose is to determine the valuations of energy in the auction, optimally schedule energy distribution, and strategically purchase and sell energy with the current electricity prices. Simulations based on real data show that each individual microgrid, under the management of the proposed algorithm, can achieve a time-averaged profit that is arbitrarily close to an optimum value, while avoiding compromising its own comfort.

description: The goal of this study is to analyze the importance of Support for Infrastructure Projects and Services in Territories (Proinf) in the recent financing of economic production structure of family farming rural areas of the Northeast Brazil. The idea is to assess projects as actions of productive inclusion and social management, to the economic dynamism of territories. The methodology has already been defined by the Territorial Development Secretariat (SDT), and field research make using the questionnaire Investment Project Evaluation (Q5). Visits were performed on each project and 18 questionnaires were sent to members of the territorial boards of six evaluated and monitored projects. As a result, it was noted that few projects were implemented, especially family farms, and that any of these works. This result points to the urgency in the institutional arrangement of the adjustment in the territories and to seek ways to overcome weaknesses in the management structures and economic production of family farming, especially in the Açu-Mossoró and Sertão do Apodi (RN) territories.

description: We study the effects of the magnetic field on the dynamics of non-rotating stellar cores by performing two-dimensional (2D), magnetohydrodynamics (MHD) simulations. To this end, we have updated our neutrino-radiation-hydrodynamics supernova code to include MHD employing a divergence cleaning method with both careful treatments of finite volume and area reconstructions. By changing the initial strength of the magnetic field, the evolution of $15.0$, $18.4$ and $27.0$ $M_\odot$ presupernova progenitors is investigated. An intriguing finding in our study is that the neutrino-driven explosion occurs regardless of the strength of the initial magnetic field. For the 2D models presented in this work, the neutrino heating is the main driver for the explosion, whereas the magnetic field secondary contributes to the pre-explosion dynamics. Our results show that the strong magnetic field weakens the growth of the neutrino-driven turbulence in the small scale compared to the weak magnetic field. This results in the slower increase of the turbulent kinetic energy in the postshock region, leading to the slightly delayed onset of the shock revival for models with the stronger initial magnetic field.

description: The article attempts a synthetic overview of Wojtek Blecharz’s major theatrical projects, including specifically his opera productions, such as Transcryptum, Park-Opera, Body-Opera, Fiasko(Fiasco) and Rechnitz-Opera (Anioł Zagłady (The Exterminating Angel)). What these shows have in common is a clear tendency to transcend traditional operatic conventions, associated with both the form of the genre and its reception.

The composer’s musical and theatrical experiments focus on sound – its performativity and inseparable link to corporality. The privileging of the body and musical gesture goes hand in hand with enhancing the visual aspect of music, which makes it possible to see even Blecharz’s autonomous compositions in terms of performance and often also instrumental theatre. This article presents the operatic work of Blecharz against the background of contemporary theories related to the performativity of music and its intermedia contexts.

Thin spray-on liners : assessment of support performance under dynamic loading conditions
Creators: name: Moreau, Lindsay Honor
Publisher: name: University of British Columbia
Year: 2010

description: The effectiveness of ground support systems under dynamic loading conditions is of prime interest to the mining industry for the successful and safe operation of deep mining operations. All ground support systems must have static capacity to provide stability against gravity induced failure mechanisms. However, to ensure excavation stability and safety in seismically active areas and in blasting environments, the support system must also offer dynamic capacity. A method of measuring and quantifying the dynamic capacity of ground support systems has yet to be established. There have been some attempts at measuring dynamic capacity in a laboratory setting, however very little information exists on large-scale in-situ testing programs. Proposed within this thesis is a large-scale dynamic load test methodology and analysis technique. The focus of this large-scale dynamic load test program was to collect support performance data specific to thin spray-on liners (TSLs), as it pertains to dynamic loading. To fully examine support performance, multiple data types were collected throughout the testing program. The integration of the various data types and formats required a unique analysis process, from which the dynamic limit of five ground support systems was defined. The definition of the dynamic limit allows for an improved underground support design in areas of anticipated seismicity. With the availability of dynamic load capacity data, a refinement of the support design for TSL systems in underground excavations was possible. The CRRP (Canadian Rockburst Research Program) have proposed a support design guideline for dynamic loading conditions. Additionally, Espley and Kaiser have developed a unique support design guideline specific to TSLs. The author expanded the existing TSL support design proposed by Espley and Kaiser by including a dynamic loading component. Through integration of the design principles proposed in the CRRP with the existing TSL design guideline, an improved TSL support design process was generated.

description: The J-flow of S. K. Donaldson and X. X. Chen is a parabolic flow on Kahler manifolds with two Kahler metrics. It is the gradient flow of the J-functional which appears in Chen's formula for the Mabuchi energy. We find a positivity condition in terms of the two metrics which is both necessary and sufficient for the convergence of the J-flow to a critical metric. We use this result to show that on manifolds with ample canonical bundle, the Mabuchi energy is proper on all Kahler classes in an open neighborhood of the canonical class defined by a positivity condition. This improves previous results of Chen and of the second author. We discuss the implications of this for the problem of the existence of constant scalar curvature Kahler metrics. We also study the singularities of the J-flow and, under certain conditions (which always hold for dimension two) derive estimates away from a subvariety. In the case of Kahler surfaces we use these estimates to confirm, at least in a certain sense, a conjectural remark of Donaldson that if the J-flow does not converge then it should blow up over some curves of negative self-intersection.

description: The random forced Navier-Stokes equation can be obtained as a variational problem of a proper action. By virtue of incompressibility, the integration over transverse components of the fields allows to cast the action in the form of a large deviation functional. Since the hydrodynamic operator is nonlinear, the functional integral yielding the statistics of fluctuations can be practically computed by linearizing around a physical solution of the hydrodynamic equation. We show that this procedure yields the dimensional scaling predicted by K41 theory at the lowest perturbative order, where the perturbation parameter is the inverse Reynolds number. Moreover, an explicit expression of the prefactor of the scaling law is obtained.

description: We generalize the idea of the axion to an extended electroweak gauge symmetry setup. We propose a minimal axion extension of the Singer-Valle-Schechter (SVS) theory, in which the standard model fits in $\mathrm{SU(3)_L\otimes U(1)_X}$, the number of families results from anomaly cancellation, and the Peccei-Quinn (PQ) solution to the strong-CP problem is implemented. Neutrino masses arise from a type-I Dirac seesaw mechanism, suppressed by the ratio of SVS and PQ scales, suggesting the existence of new physics at a moderate SVS scale. Novel features include an enhanced axion coupling to photons when compared to the DFSZ axion, as well as flavour-changing axion couplings to quarks.

description: Prospective searches for lepton flavor violation (LFV) in rare kaon decays at the existing and future intermediate-energy accelerators are considered. The proposed studies are complementary to LFV searches in muon-decay experiments and offer a unique opportunity to probe models with approximately conserved fermion-generation quantum number with sensitivity superior to that in other processes. Consequently, new searches for LFV in kaon decays are an important and independent part of the general program of searches for lepton flavor violation in the final states with charged leptons.
description: 30 pages, 10 figures. An extended version of the talk given at the Chicago Flavor Seminar, February 27, 2004. In the new version some misprints were corrected and some new data for LFV-processes were added. The main content of the paper was not changed. The paper is published in Yad. Fiz. 68, 1272 (2005)

description: The characteristics of the chiral phase transition are analyzed within the framework of chiral quark models with nonlocal interactions in the mean field approximation. In the chiral limit, we develop a semi-analytic framework which allows us to explicitly determine the phase transition curve, the position of the critical points, some relevant critical exponents, etc. For the case of finite current quark masses, we show the behavior of various thermodynamical and chiral response functions across the phase transition.

description: Precision landing on large and small planetary bodies is a technology of utmost importance for future human and robotic exploration of the solar system. In this context, the Zero-Effort-Miss/Zero-Effort-Velocity (ZEM/ZEV) feedback guidance algorithm has been studied extensively and is still a field of active research. The algorithm, although powerful in terms of accuracy and ease of implementation, has some limitations. Therefore with this paper we present an adaptive guidance algorithm based on classical ZEM/ZEV in which machine learning is used to overcome its limitations and create a closed loop guidance algorithm that is sufficiently lightweight to be implemented on board spacecraft and flexible enough to be able to adapt to the given constraint scenario. The adopted methodology is an actor-critic reinforcement learning algorithm that learns the parameters of the above-mentioned guidance architecture according to the given problem constraints.

description: Das Auslaufen der Milchquote zum 1. April 2015 wird zum Anlass genommen, eine Anpassung bestehender Milchlieferverträge unter Berücksichtigung der Einstellungen und Präferenzen der Landwirte zu analysieren. Anhand einer empirischen Untersuchung von 161 Milcherzeugern wird überprüft, wie die Präferenzen für bestimmte Vertragsparameter (Preisfindung, Mengenregelung und Vertragsdauer) ausfallen und ob generelle Einstellungen zu Verträgen die Vertragsauswahl beeinflussen. Die Ergebnisse unterstreichen, dass eine hohe Genossenschaftspräferenz, großes Preisvertrauen und eine bestehende Strategie zur Betriebsentwicklung die Auswahlwahrscheinlichkeit des klassischen Genossenschaftsvertrags erhöht. Aus den Ergebnissen werden abschließend Implikationen für das Vertragsmanagement von Molkereien abgeleitet. As a result of the expiry of the EU milk quota on April 1st 2015, raw milk procurement in the German dairy industry faces major changes. Delivery contracts between dairy farmers and milk processors are the basic coordination mechanism of business relationships and need thus to be adapted to the altered market situation. We analyze empirically the farmers’ preferences for different stipulations (pricing systems, volume control and the duration of the contract) and test if their attitudes towards contracting in general have an influence on contract choice. Results illustrate that farmer-suppliers’ preference for cooperatives, trust in prices and a focus on entrepreneurial goals increases the likelihood to choose the classical cooperative contract. Based on the results, we discuss implications for contract management in dairies.

description: Price transmission analysis is an increasing research topic, especially for price taking countries such as Costa Rica. We describe the beef supply chain and provide a numerical implementation of Vector Error Correction Model (VECM) of price transmission for the meat market in order to observe the relationship between import prices of meat and their effects on national retail prices. To restore equilibrium, retail prices correct 8% of the error term monthly. Since the meat imports market of Costa Rica is complex, the analysis of others business partners as Nicaragua should be included in order to compare the influence of these in local retail prices
Prediction of site-specific amino acid distributions and limits of divergent evolutionary changes in protein sequences

description: We derive an analytic expression for site-specific stationary distributions of amino acids from the Structurally Constrained Neutral (SCN) model of protein evolution with conservation of folding stability. The stationary distributions that we obtain have a Boltzmann-like shape, and their effective temperature parameter, measuring the limit of divergent evolutionary changes at a given site, can be predicted from a site-specific topological property, the principal eigenvector of the contact matrix of the native conformation of the protein. These analytic results, obtained without free parameters, are compared with simulations of the SCN model and with the site-specific amino acid distributions obtained from the Protein Data Bank. These results also provide new insights into how the topology of a protein fold influences its designability, i.e. the number of sequences compatible with that fold. The dependence of the effective temperature on the principal eigenvector decreases for longer proteins, a possible consequence of the fact that selection for thermodynamic stability becomes weaker in this case.
