On the two-loop hexagon Wilson loop remainder function in N=4 SYM
Creators: name: Zhang, Jian-Hui
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A duality relation has been proposed between the planar gluon MHV amplitudes and light-like Wilson loops in N=4 super Yang-Mills. At six-point two-loop, the results for the planar gluon MHV amplitude and for the light-like Wilson loop agree, but they both differ from the Bern-Dixon-Smirnov ansatz by a finite remainder function. Recently Del Duca, Duhr and Smirnov presented an analytical result for the two-loop hexagon Wilson loop remainder function in general kinematics. Their result is rather lengthy, and the dependence on the conformal cross ratios appears in a complicated way. Here we present an alternate, more compact representation for the two-loop hexagon Wilson loop remainder function.

description: Excerpts from the report: Major objectives of this study were to determine present-day importance of patronage refunds in operating at cost, distributing savings, and financing operations of regional marketing cooperatives; to identify and classify different methods individual regionals use in distributing net margins or savings; and to analyze and evaluate effectiveness of these methods in providing services on a cost basis. FCS sought specific information on (1) disposition of net margins for the fiscal year association last realized such margins, (2) methods used in calculating refunds on a patronage basis, (3) recent changes in methods or procedures of allocating or distributing net margins to patrons on a business volume basis, (4) procedures used in distributing refunds, and (5) trends in composition and size of patronage refunds from 1961 through 1965.
Pauli-Villars regularization of field theories on the light front
Creators: name: Hiller, J. R.
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Four-dimensional quantum field theories generally require regularization to be well defined. This can be done in various ways, but here we focus on Pauli--Villars (PV) regularization and apply it to nonperturbative calculations of bound states. The philosophy is to introduce enough PV fields to the Lagrangian to regulate the theory perturbatively, including preservation of symmetries, and assume that this is sufficient for the nonperturbative case. The numerical methods usually necessary for nonperturbative bound-state problems are then applied to a finite theory that has the original symmetries. The bound-state problem is formulated as a mass eigenvalue problem in terms of the light-front Hamiltonian. Applications to quantum electrodynamics are discussed.

L’alveare dei pensieri

Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2016

description: La sperimentazione si svolge in una classe di quarta elementare dell’Istituto scolastico di Minusio- Cadogno, classe composta da 23 allievi. Lo scopo è di scoprire se, la proposta di uno sfondo motivazionale come la lettura di un libro, permette agli allievi di esprimersi sui propri interessi, le proprie preoccupazioni e i propri pensieri. Oltre a ciò, permette di valutare la necessità di proporre agli allievi la possibilità di raccontarsi e narrarsi e di evidenziare quali benefici o ricadute si possono ottenere per il singolo allievo e per il gruppo classe. La sperimentazione vuole inoltre scoprire come gli allievi valutano, in termini di difficoltà o facilità, la capacità di esternare i propri pensieri tramite la scrittura. Dai dati raccolti attraverso 157 pensieri espressi nelle varie categorie e 23 questionari compilati, si può osservare che gli allievi hanno accolto positivamente la possibilità di esprimersi, hanno manifestato dei miglioramenti del proprio stato d’animo dopo la scrittura dei pensieri, e hanno proposto validi aiuti. Malgrado alcune difficoltà incontrate, sia per paura, sia per la complessità relativa ad alcune categorie richieste, l’esternazione dei pensieri ha comunque portato dei benefici sia per il singolo allievo, (leggerezza, libertà, tranquillità, ecc.), sia per il gruppo classe, soprattutto per quel che concerne l’aspetto collaborativo, il rispetto e l’empatia.

description: We show that the correlation functions of ghosts and gluons for the pure Yang-Mills theory in Landau gauge can be accurately reproduced for all momenta by a one-loop calculation. The key point is to use a massive extension of the Faddeev-Popov action. The agreement with lattice simulation is excellent in d=4. The one-loop calculation also reproduces all the characteristic features of the lattice simulations in d=3 and naturally explains the pecularities of the propagators in d=2.

description: We study excitonic polariton relaxation and propagation in bulk CdZnTe using time- resolved photoluminescence and time-of-flight techniques. Propagation of picosecond optical pulses through 0.745 mm thick crystal results in time delays up to 350 ps, depending on the photon energy. Optical pulses with 150 fs duration become strongly stretched. The spectral dependence of group velocity is consistent with the dispersion of the lower excitonic polariton branch. The lifetimes of excitonic polariton in the upper and lower branches are 1.5 and 3 ns, respectively.

Study of solar and other unknown anti-neutrino fluxes with Borexino at LNGS
Creators: name: Bellini, G.

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: We report on the search for anti-neutrinos of yet unknown origin with the Borexino detector at the Laboratori Nazionali del Gran Sasso. In particular, a hypothetical anti-neutrino flux from the Sun is investigated. Anti-neutrinos are detected through the neutron inverse $β$ decay reaction in a large liquid organic scintillator target. We set a new upper limit for a hypothetical solar $\barν_e$ flux of 760 ${\rm cm}^{-2}{\rm s}^{-1}$, obtained assuming an undistorted solar $^8$B energy spectrum. This corresponds to a limit on the transition probability of solar neutrinos to anti-neutrinos of $1.3\times10^{-4}$ (90\% C.L.) for $E_{\barν}>1.8$ MeV, covering the entire $^{8}$B spectrum. Best differential limits on anti-neutrino fluxes from unknown sources are also obtained between the detection energy threshold of 1.8 MeV and 17.8 MeV with more than 2 years of data.

Characterization of non-metal fraction of waste printed circuit boards to promote recycling
Creators: name: Kumar, Amit
Publisher: name: University of British Columbia
Year: 2020

description: Electrical and electronic equipment has become an integral part of modern society. With the current technological advances, the life span of this equipment has been shrinking, leading to waste generation and issues related to end-of-life waste disposal. The circular economy model has been proposed to address the growing volume of e-waste. The model encourages reduction and reuse to decrease waste generation and encourages recycling to promote efficient natural resource usage. One of the challenges with promoting the circular economy model for e-waste is the insufficiency or absence of the recycling process for the non-metal fraction. The low value associated with the non-metal fraction increases its probability of being disposed of in landfills. This research explored the possibility of utilizing low-cost physical separation processes common in the mineral processing industry to recycle the non-metal fraction obtained from waste printed circuit board. The study showed that a density-based separation could theoretically be used to separate organic, inorganic, and residual metal streams from the non-metal fraction, thus increasing its reusability. The float-sink test and derived washability curves and washability indices showed that a conceptual three-product gravity separation process could produce an organic fraction with 47% yield at 86% organic content and a reject stream with a 35% yield at 72% fiberglass content. A gravity separation-based flowsheet was proposed for the recycling of non-metal fraction, and the potential applications of the recycled products were identified. Further test work at the pilot level would be required to estimate the process efficiency, related costs and understand the product characteristics for their proper application. This research also provided a simplified approach for determining the loss on ignition that can be used to estimate the separation efficiency. It also showed the applicability of advanced techniques such as inverse gas chromatography and micro-FTIR for analyzing the surface heterogeneity and polymeric identification of non-metal fraction components. Overall, the research used an interdisciplinary approach to provide a potential solution for the non-metal fraction to the recycling industry using tools and processes used in the coal and mineral processing industry.
Complete Reconstruction of the Wavefunction of a Reacting Molecule by Four-Wave Mixing Spectroscopy

description: Probing the real time dynamics of a reacting molecule remains one of the central challenges in chemistry. In this letter we show how the time-dependent wavefunction of an excited-state reacting molecule can be completely reconstructed from resonant coherent anti-Stokes Raman spectroscopy. The method assumes knowledge of the ground-state potential but not of any excited-state potential, although we show that the latter can be computed once the time-dependent excited-state wavefunction is known. The formulation applies to polyatomics as well as diatomics and to bound as well as dissociative excited potentials. We demonstrate the method on the Li$_2$ molecule with its bound first excited-state, and on a model Li$_2$-like system with a dissociative excited state potential.

description: The Two Micron All-Sky Survey (2MASS) has provided a uniform photometric catalog to search for previously unknown red AGN and QSOs. We have extended the search to the southern equatorial sky by obtaining spectra for 1182 AGN candidates using the 6dF multifibre spectrograph on the UK Schmidt Telescope. These were scheduled as auxiliary targets for the 6dF Galaxy Redshift Survey. The candidates were selected using a single color cut of J - Ks > 2 to Ks ~ 15.5 and a galactic latitude of |b|>30 deg. 432 spectra were of sufficient quality to enable a reliable classification. 116 sources (or ~27%) were securely classified as type 1 AGN, 20 as probable type 1s, and 57 as probable type 2 AGN. Most of them span the redshift range 0.0520%) than in any previous galaxy survey. A small fraction of the type 1 AGN could have their optical colors reddened by optically thin dust with A_V<2 mag relative to optically selected QSOs. A handful show evidence for excess far-IR emission. The equivalent width (EW) and color distributions of the type 1 and 2 AGN are consistent with AGN unified models. In particular, the EW of the [OIII] emission line weakly correlates with optical--near-IR color in each class of AGN, suggesting anisotropic obscuration of the AGN continuum. Overall, the optical properties of the 2MASS red AGN are not dramatically different from those of optically-selected QSOs. Our near-IR selection appears to detect the most near-IR luminous QSOs in the local universe to z~0.6 and provides incentive to extend the search to deeper near-IR surveys.

The asymptotic conditional bias and variance of the estimator are provided and its good performance is illustrated on some finite sample situations.

È dunque necessario rinnovarla attraverso l’adozione di tecnologie innovative, supportate dal Servizio Informatico della SUPSI. In particolare, occorre introdurre nuove funzionalità per semplificare la gestione e l’estrazione dei dati, e per agevolare la ricerca dei progetti e facilitarne la condivisione tra utenti. In questo lavoro di diploma é stato sviluppato un nuovo software lato server per la gestione dei progetti, il quale include un'Application Programming Interface con la quale potrá interfacciarsi un nuovo client frontend._____The management of semester and diploma projects at the Department of Innovative Technologies, at the University of Applied Sciences of Italian-speaking Switzerland, is an important and resource-intensive activity involving both faculty and students. To enhance communication among stakeholders and streamline the management process, over ten years ago, the "Progetti di studio" platform was launched. However, over the years, the needs and expectations of platform users have evolved, while the platform itself has not. Therefore, it is necessary to revamp it through the adoption of innovative technologies, supported by the IT Service of SUPSI. In particular, new features need to be introduced to simplify data management and extraction, as well as to facilitate project search and sharing among users. In this diploma project, a new server-side software for project management has been developed, which includes a Application Programming Interface to be interfaced with a new frontend client.

description: We isolate a sample of 43 upper RGB stars in the extreme outer halo Galactic globular cluster NGC 2419 from two Keck/DEIMOS slitmasks. The probability that there is more than one contaminating halo field star in this sample is extremely low. Analysis of moderate resolution spectra of these cluster members, as well as of our Keck/HIRES high resolution spectra of a subsample of them, demonstrates that there is a small but real spread in Ca abundance of ~ 0.2 dex within this massive metal-poor globular cluster. This provides additional support to earlier suggestions that NGC 2419 is the remnant of a dwarf galaxy accreted long ago by the Milky Way.

description: This is the second in a series of papers that develops the theory of reflection monoids, motivated by the theory of reflection groups. Reflection monoids were first introduced in arXiv:0812.2789. In this paper we study their presentations as abstract monoids. Along the way we also find general presentations for certain join-semilattices (as monoids under join) which we interpret for two special classes of examples: the face lattices of convex polytopes and the geometric lattices, particularly the intersection lattices of hyperplane arrangements. Another spin-off is a general presentation for the Renner monoid of an algebraic monoid, which we illustrate in the special case of the "classical" algebraic monoids.

Soft law and international relations : the arctic, outer space, and climate change
Creators: name: Nadarajah, Hema
Publisher: name: University of British Columbia
Year: 2020

description: Soft law has been observed to be increasing within the global system, particularly in regions and issue-areas where scientific and technological knowledge has been substantively integrated into decision-making and governance. The often-used assumption for the prevalence of such instruments has been the uncertainty of scientific knowledge. This dissertation examines this assumption and takes the analysis further by examining contemporary changes to the international system, such as the number and diversity of state and non-state actors as well as their relative influence, through a close examination of three cases — the Arctic, Outer Space, and Climate Change. This dissertation makes three contributions. Firstly, it proposes that soft law instruments can be binding or non-binding. Binding soft law instruments, called “soft treaties”, are made up of permissive, ambiguous, and/or redundant obligations. Secondly, this dissertation empirically establishes that soft law instruments are becoming more prevalent, as the literature has claimed but not verified. In order to identify reasons for this prevalence, the dissertation examines a sample of significant instruments using a mixed methodology that encompasses legal textual analysis, a review of the International Relations and International Law literature, and interviews with academics and practitioners. It finds that the prevalence of soft law is an outcome of, ranked in relative importance: (1) shifting global politics arising from an increasing diversity and influence of states and non-state actors; (2) coordination despite mutual suspicion; (3) the desire for states to paper over differences; (4) a desire to avoid constitutional constraints domestically; (5) the promotion of epistemic communities; (6) a desire to be seen as doing something, and; (7) the gradual crystallization of harder law. Thirdly, this dissertation examines the potential implications of these findings which are: (1) the increased opportunities for states to forum shop; (2) the rise in complacency about soft law-making that may arise from consensus-based decision making structures; (3) the establishment of path dependency to cooperate within discrete areas despite diplomatic challenges elsewhere, and; (4) the non-linear evolution of written international law. In broadening the definition of soft law, this dissertation contributes to understanding the dynamics between International Relations and International Law.

Dielectric heating advanced oxidation process for resource recovery of organic wastewater slurries
Creators: name: Ries, Sarah
Publisher: name: University of British Columbia
Year: 2020

description: H₂O₂-advanced oxidation process facilitated by microwave (MW-AOP) or radiofrequency (RF-OP) was investigated for release of valuable products from three organic slurries: fats, oils, and grease (FOG), thickened waste activated sludge (TWAS), and dairy manure. Mixtures of FOG either with dairy manure or with TWAS were treated using MW-AOP (batch 2450MHz, 1kW). The degradation followed peroxidation mechanism to produce lower molecular weight substrates such as short-chain fatty acids which would be less inhibitory to microbes. Nutrients and metals released in the treated solution would sustain microbial growth in a biological system. FOG content for the mixtures in the MW-AOP treatment should be less than 75% by total solids (TS) weight to prevent oxidation to CO₂. RF-OP (batch 27.12MHz, 6kW) was utilized to treat solid fraction dairy manure for disintegration of solids and nutrient release. High H₂O₂ dosages above 1 gH₂O₂/gTS required a longer hold time for full reaction, resulting in improved release of nutrients and soluble chemical oxygen demand but increase in the process cost and treatment time. The results indicated that the energy consumption during this process was greater than the energy potential of the substrate indicating that it is probably not cost effective for the treatment of separated dairy manure solids. A pilot-scale 915MHz, 25kW continuous-flow MW-AOP system was operated treating TWAS, which was then fed continuously into a single up-flow anaerobic sludge reactor (UASB) reactor, or a two-phase UASB system consisting of a completely stirred tank reactor (CSTR) in acid phase and UASB in methane phase. The organic loading rate (OLR) reached maximum of 15.7 – 18.2 g volatile solids(VS)/L/day in all reactors without evidence of souring; There was no difference in specific methane potential (SMP) between CSTR and UASB reactors. VFA accumulated in the acid phase when SRT was less than 1 day. In both systems the SMP was maintained between 10.1 and 18.2 gVS/L/day at 133±45 and 138±73 LCH4/VS-added for single and two-phase system respectively. Theoretical methane yield was achieved between 7 – 8 day HRT. No difference between the two systems in terms of methane performance as a function of hydraulic retention time was determined.

description: Excerpts from the report: In recent years, farm supply cooperatives, as well as other business firms, have become interested in combining their resources to strengthen their economic position in an increasingly competitive agricultural economy. Many cooperative leaders foresee advantages of unification through added purchasing power, increased efficiency in facility and personnel use, diversification of product lines, improved services to members, increased savings, and the like. Others foresee problems and disadvantages of both an economic and a non-economic nature. Both groups, as well as representatives of regional cooperatives, universities, and other institutions, desire more information on merger procedures used, problems encountered and solved, and results of mergers after several years of operation. The broad purposes of the study reported on here were: (1) To determine developments leading to unification of selected local farm supply cooperatives in the Midwest and the results of these mergers, and (2) to provide guidelines and standards of use to other cooperatives, Farmer Cooperative Service, land-grant universities, and others in determining the feasibility of proposed mergers.

description: We compute the charm dijet photoproduction cross section at next-to-leading order of QCD in the zero-mass variable flavour number scheme, i.e. with active charm quarks in the proton and photon. The results are compared to recent measurements from the ZEUS experiment at HERA. The predictions for various distributions agree well with the data, in particular for large momentum fractions of the the partons in the photon, where direct photon processes dominate. At low momentum fractions, the predictions are quite sensitive to the charm content in the photon. The experimental data are shown to favour parameterizations with a substantial charm quark density such as the one proposed by Cornet et al.

description: We report interesting anomalies in the temperature dependent Raman spectra of FeSe$_{0.82}$ measured from 3K to 300K in the spectral range from 60 to 1800 cm$^{-1}$ and determine their origin using complementary first-principles density functional calculations. A phonon mode near 100 cm$^{-1}$ exhibits a sharp increase by $\sim$ 5% in frequency below a temperature T$_s$ ($\sim$ 100 K) attributed to strong spin-phonon coupling and onset of short-range antiferromagnetic order. In addition, two high frequency modes are observed at 1350 cm$^{-1}$ and 1600 cm$^{-1}$, attributed to electronic Raman scattering from ($x^2-y^2$)to $xz$ / $yz$ $d$-orbitals of Fe.

description: Quantum state tomography, the ability to deduce the state of a quantum system from measured data, is the gold standard for verification and benchmarking of quantum devices. It has been realized in systems with few components, but for larger systems it becomes infeasible because the number of quantum measurements and the amount of computation required to process them grows exponentially in the system size. Here we show that we can do exponentially better than direct state tomography for a wide range of quantum states, in particular those that are well approximated by a matrix product state ansatz. We present two schemes for tomography in 1-D quantum systems and touch on generalizations. One scheme requires unitary operations on a constant number of subsystems, while the other requires only local measurements together with more elaborate post-processing. Both schemes rely only on a linear number of experimental operations and classical postprocessing that is polynomial in the system size. A further strength of the methods is that the accuracy of the reconstructed states can be rigorously certified without any a priori assumptions.

The effects of cavity on the etendue of a light source

Year: 2011
Subjects: subject: Optics (physics.optics)

description: The simulation proposes that the cylindrical cavity around a circular light source can decreases the divergence angle without changing the emission energy and source size. This result can provide a way to reduce the etendue of the light source by scrambling the rays inside the cavity with a lossless scattering surface. The experiment demonstrates that the metallic cavity around the surface source reduces the divergence angle. However, the metallic surface also absorbs quite a large portion of the light energy. The Lambertian nature of the sidewall surface changes the directions of the rays into horizontal directions. It increases the number of reflection inside the cavity and amplifies the small amount of absorption at a single reflection. The effect of the cavity on the etendue of the light source can contributes to providing more design flexibility in various lighting applications.

description: Ellesmere Island, at the most northerly tip of Canada, possesses the highest mountain peaks within 10 degrees of the pole. The highest is 2616 m, with many summits over 1000 m, high enough to place them above a stable low-elevation thermal inversion that persists through winter darkness. Our group has studied four mountains along the northwestern coast which have the additional benefit of smooth onshore airflow from the ice-locked Arctic Ocean. We deployed small robotic site testing stations at three sites, the highest of which is over 1600 m and within 8 degrees of the pole. Basic weather and sky clarity data for over three years beginning in 2006 are presented here, and compared with available nearby sea-level data and one manned mid-elevation site. Our results point to coastal mountain sites experiencing good weather: low median wind speed, high clear-sky fraction and the expectation of excellent seeing. Some practical aspects of access to these remote locations and operation and maintenance of equipment there are also discussed.

description: It has recently been shown that light can be stored in Bose-Einstein condensates for over a second. Here we propose a method for realizing a controlled phase gate between two stored photons. The photons are both stored in the ground state of the effective trapping potential inside the condensate. The collision-induced interaction is enhanced by adiabatically increasing the trapping frequency and by using a Feshbach resonance. A controlled phase shift of $π$ can be achieved in one second.
