description: For cosmic neutrinos we study the conditions and the effects of the coherence loss as well as coherent broadening of the spectrum. We evaluate the width of the neutrino wavepacket produced by charged particles under various circumstances: in an interaction-free environment, in a radiation-dominated medium (typical of the sources of the gamma ray bursts) and in the presence of a magnetic field. The effect of the magnetic field on the wavepacket size appears to be more important than the scattering. If the magnetic field at the source is larger than $\sim$10 Gauss, the coherence of neutrinos will be lost while traveling over cosmological distances. Various applications of these results have been considered. We find that for large magnetic fields ($B> 10^9$ Gauss) and high energies ($E_ν>{\rm PeV}$), "coherent broadening" can modify the energy spectrum of neutrinos. In the coherent case, averaging out the oscillatory terms of the probabilities does not induce any statistical uncertainty beyond what expected in the absence of these terms. A deviation from the standard quantum mechanics that preserves average energy and unitarity cannot alter the picture.

description: We review the description of the lowest-energy nucleon excitation -- the $Δ$(1232)-resonance. Much of the recent experimental effort has been focused on the precision measurements of the nucleon-to-$Δ$ transition by means of electromagnetic probes. We confront the results of these measuremnts with the state-of-the-art calculations based on chiral effective-field theories (EFT), lattice QCD, large-$N_c$ relations, perturbative QCD, and QCD-inspired models. We also discuss the link of the nucleon-to-$Δ$ form factors to generalized parton distributions (GPDs). Some of the theoretical approaches are reviewed in detail, in particular, recent dynamical and unitary-isobar models of pion electroproduction, which are extensively used in the interpretation of experiments. Also, the novel extension of chiral EFTs to the energy domain of the $Δ$-resonance is described in detail. The two-photon exchange effects in the electroexcitation of the $\De$-resonance are addressed here as well.

description: In any ‘omics study, significant patterns in data often become apparent only when looking at the right scale. For instance, when clustering single-cell transcriptomes, is the analysis tuned to discover broad or specific cell types? Likewise, protein communities revealed from protein networks can vary widely in size depending on the method. Here, we use the concept of “persistent homology” drawn from mathematical topology, to develop a computational method, termed HiDeF (Hierarchical community Decoding Framework) for identifying robust structures in data at all scales simultaneously. HiDeF outperformed alternative approaches that do not consider the persistence of structures in benchmark experiments with simulated data and real-world datasets of single-cell transcriptomics and protein interactions. Comparative analysis of protein-protein interaction networks found significant differences in the distributions of community sizes across networks generated with different measurement approaches. HiDeF could facilitate biological discovery within large ‘omics data, such as expanding the catalog of identified cell types in single-cell transcriptomics data and identifying protein modules from multi-omics protein networks. The method has been integrated into CDAPS (Community Detection APplication and Service), a Cytos- cape-based software framework, and also available as a Python package.

description: In any business, record keeping is a financial priority. In agriculture, record keeping can help producers understand the breakeven value, cost structure and profitability drivers for their business. A major benefit can also be analysis of financial health. University of Tennessee Extension has developed the Dairy Gauge Benchmarking program to help dairy producers better understand what their financial statements suggest about financial health. Within the program, there are three areas that were developed specifically for gauging a dairy business’s health. The three areas are 1) balance sheet and profitability dairy benchmarks, 2) dairy feed benchmarks, and 3) dairy non-feed income and expense benchmarks. This publication is focused on the non-feed income and expense benchmarks.
X-ray irradiation in XTE J1817-330 and the inner radius of the truncated disc in the hard state

description: The key aspect of the very successful truncated disc model for the low/hard X-ray spectral state in black hole binaries is that the geometrically thin disc recedes back from the last stable orbit at the transition to this state. This has recently been challenged by direct observations of the low/hard state disc from CCD data. We reanalyze the Swift and RXTE campaign covering the 2006 outburst of XTE J1817-330 and show that these data actually strongly support the truncated disc model as the transition spectra unambiguously show that the disc begins to recede as the source leaves the disc dominated soft state. The disc radius inferred for the proper low/hard state is less clear-cut, but we show that the effect of irradiation from the energetically dominant hot plasma leads to an underestimate of the disc radius by a factor of 2-3 in this state. This may also produce the soft excess reported in some hard-state spectra. The inferred radius becomes still larger when the potential difference in stress at the inner boundary, increased colour temperature correction from incomplete thermalization of the irradiation, and loss of observable disc photons from Comptonization in the hot plasma are taken into account. We conclude that the inner disc radius in XTE J1817-330 in the low/hard spectral state is at least 6-8 times that seen in the disc dominated high/soft state, and that recession of the inner disc is the trigger for the soft--hard state transition, as predicted by the truncated disc models.

description: We study the resonating valence bond (RVB) theory of the Hubbard-Heisenberg model on the half-filled anisotropic triangular lattice. Varying the frustration changes the wavevector of maximum spin correlation in the Mott insulating phase. This, in turn, changes the symmetry of the superconducting state, that occurs at the boundary of the Mott insulating phase. We propose that this physics is realised in several families of quasi-two-dimensional organic superconductors.

description: Selecting appropriate distributed join methods for logical join operations in a query plan is crucial for the performance of data-intensive scalable computing (DISC). Different network communication patterns in the data exchange phase generate varying network communication workloads and significantly affect the distributed join performance. However, most cost-based query optimizers focus on the local computing cost and do not precisely model the network communication cost. We propose a cost model for various distributed join methods to optimize join queries in DISC platforms. Our method precisely measures the network and local computing workloads in different execution phases, using information on the size and cardinality statistics of datasets and cluster join parallelism. Our cost model reveals the importance of the relative size of the joining datasets. We implement an efficient distributed join selection strategy, known as RelJoin in SparkSQL, which is an industry-prevalent distributed data processing framework. RelJoin uses runtime adaptive statistics for accurate cost estimation and selects optimal distributed join methods for logical joins to optimize the physical query plan. The evaluation results on the TPC-DS benchmark show that RelJoin performs best in 62 of the 97 queries and can reduce the average query time by 21% compared with other strategies.

description: We study the back-reaction of fermion fields on the kink solution in one space and one time dimension. We employ a variational procedure to determine an upper limit for the minimum of the total energy. This energy has three contributions: the classical kink energy, the energy of valence fermions and the fermion vacuum polarization energy. The latter arises from the interaction of the kink with the Dirac sea and is required for consistency of the semi-classical expansion for the fermions. Earlier studies only considered the valence part and observed a substantial back-reaction. This was reflected by a sizable distortion of the kink profile. We find that this distortion is strongly mitigated when the Dirac sea is properly accounted for. As a result the back-reaction merely produces a slight squeeze or stretch of the kink profile.

Li Shangyin : the poetry of allusion
Creators: name: Yu, Teresa Yee-Wah
Publisher: name: University of British Columbia
Year: 2011

description: A major poet of the Tang period, Li Shangyin is highly regarded yet criticized because his work is densely allusive. Dazzling and rich in meaning, it is also difficult and obscure because of its pervasive allusiveness. Chapter I reviews critical opinion of Li's use of allusion. Many traditional critics see allusion as an ornamental rhetorical device and consider Li's profuse allusiveness an idiosyncrasy to be tolerated in an esteemed poet. Chapter II studies allusion broadly and precisely as a literary concept: generally, allusion is a "connector" of texts, a link between a poet's work and his literary heritage; specifically, it is a linguistic device serving metaphorical functions. Allusion viewed as extended metaphor generates multiple meanings. An approach to reading allusion is here developed, to interpret allusive texts on literal, allegorical, and symbolic levels. The chapter concludes that it is a misconception to say that the heavy use of allusion necessarily leads to inferior poetry. Chapter III relates Li's allusions to major motifs in his work, finding that his historical and mythological allusions fall into clusters and patterns. The profusion of mythological allusions yields symbolic meanings, both in individual poems and in the larger context of his collected works. Examining Li's characteristic use of allusion, the chapter shows how it functions as a major stylistic signature and is the principal reason for the plurisignation and ambiguity in his poetry. Chapter IV interprets several typical poems by Li Shangyin in the context of the theoretical and historical framework of the foregoing chapters. It highlights some of the major functions of allusion in these poems. A positive response to the plurisignation of Li's allusive mode allows for an inclusive critical approach to diverse interpretations and discards those readings failing the standards of consistency, coherence, and completeness . Chapter V concludes that Li's presumed vice is his virtue: his allusive texture makes his work difficult but gives it a rewarding richness. His unique use of allusion is organic. Far from being a mere ornamental device, allusion is the very poetry itself. He creates his own poetic mode, the Poetry of Allusion.
Protostellar Turbulence Driven by Collimated Outflows

description: The majority of stars are thought to form in clusters. Cluster formation in dense clumps of molecular clouds is strongly influenced, perhaps controlled, by supersonic turbulence. We have previously shown that the turbulence in regions of active cluster formation is quickly transformed by the forming stars through protostellar outflows, and that the outflow-driven protostellar turbulence is the environment in which most of the cluster members form. Here, we take initial steps in quantifying the global properties of the protostellar turbulence through 3D MHD simulations. We find that collimated outflows are more efficient in driving turbulence than spherical outflows that carry the same amounts of momentum. Gravity plays an important role in shaping the turbulence, generating infall motions in the cluster forming region that balance the outward motions driven by outflows. The resulting quasi-equilibrium state is maintained through a slow rate of star formation, with a fraction of the total mass converted into stars per free fall time as low as a few percent. Magnetic fields are dynamically important even in magnetically supercritical clumps, provided that their initial strengths are not far below the critical value for static cloud support. We find that the mass weighted PDF of the volume density is often, although not always, approximately lognormal. The PDFs of the column density deviate more strongly from lognormal distributions. There is a prominent break in the velocity power spectrum of the protostellar turbulence, which may provide a way to distinguish it from other types of turbulence.

In particular, we provide two explicit formulae for these homomorphisms; one in terms of the Macdonald spherical functions, and another as an integral over the boundary of the building. We also determine the associated Plancherel measure, and we compute the l^2-operator norms of each basis element of A.

description: We consider a general ansatz for solving the 2-dimensional Hitchin's equations, which arise as dimensional reduction of the 4-dimensional self-dual Yang-Mills equations, with remarkable integrability properties. We focus on the case when the gauge group G is given by a real form of SL(2,C). For G=SO(2,1), the resulting field equations are shown to reduce to either the Liouville, elliptic sinh-Gordon or elliptic sine-Gordon equations. As opposed to the compact case, given by G=SU(2), the field equations associated with the noncompact group SO(2,1) are shown to have smooth real solutions with nonsingular action densities, which are furthermore localized in some sense. We conclude by discussing some particular solutions, defined on R^2, S^2 and T^2, that come out of this ansatz.

description: We report two-dimensional simulations of strongly vibrated granular materials without gravity. The coefficient of restitution depends on the impact velocity between particles by taking into account both the viscoelastic and plastic deformations of particles, occurring at low and high velocities respectively. Use of this model of restitution coefficient leads to new unexpected behaviors. When the number of particles N is large, a loose cluster appears near the fixed wall, opposite the vibrating wall. The pressure exerted on the walls becomes independent of N, and linear in the vibration velocity V, quite as the granular temperature. The collision frequency at the vibrating wall becomes independent of both N and V, whereas at the fixed wall, it is linear in both N and V. These behaviors arise because the velocity-dependent restitution coefficient introduces a new time scale related to the collision velocity near the cross over from viscoelastic to plastic deformation.

description: In the upcoming decades, one of the primary objectives in exoplanet science is to search for habitable planets and signs of extraterrestrial life in the universe. Signs of life can be indicated by thermal-dynamical imbalance in terrestrial planet atmospheres. O$_2$ and CH$_4$ in the modern Earth's atmosphere are such signs, commonly termed biosignatures. These biosignatures in exoplanetary atmospheres can potentially be detectable through high-contrast imaging instruments on future extremely large telescopes (ELTs). To quantify the signal-to-noise ($S/N$) ratio with ELTs, we select up to 10 nearby rocky planets and simulate medium resolution (R $\sim$ 1000) direct imaging of these planets using the Mid-infrared ELT Imager and Spectrograph (ELT/METIS, 3-5.6 $μ$m) and the High Angular Resolution Monolithic Optical and Near-infrared Integral field spectrograph (ELT/HARMONI, 0.5-2.45 $μ$m). We calculate the $S/N$ for the detection of biosignatures including CH$_4$, O$_2$, H$_2$O, and CO$_2$. Our results show that GJ 887~b has the highest detection $S/N$ for biosignatures and Proxima Cen b exhibits the only detectable CO$_2$ among the targets for ELT/METIS direct imaging. We also investigate the TRAPPIST-1 system, the archetype of nearby transiting rocky planet systems, and compare the biosignature detection $S/N$ of transit spectroscopy with JWST versus direct spectroscopy with ELT/HARMONI. Our findings indicate JWST is more suitable for detecting and characterizing the atmospheres of transiting planet systems such as TRAPPIST-1 that are relatively further away and have smaller angular separations than more nearby non-transiting planets.

The number of divorce cases and hence the number of single parent families are also in an upsurge. As the most significant task confronting any society is the nurturance of future generations, it is important to think about this issue seriously as this could come out of the families and project itself as a social matter in near future when the number of troubled families and children increase profoundly. In this milieu, only an efficient family education program could remediate the recurring cycle of poor parenting with the youth before they themselves become parents. Both the boy and the girl, before entering the family life should have the in-depth insight of the greater responsibility they are about to take. For that, the concept of family education should be imparted to senior secondary students as part of their curriculum, as it is practically the final stage of mass education.

description: This paper introduces SuSketch, a design tool for first person shooter levels. SuSketch provides the designer with gameplay predictions for two competing players of specific character classes. The interface allows the designer to work side-by-side with an artificially intelligent creator and to receive varied types of feedback such as path information, predicted balance between players in a complete playthrough, or a predicted heatmap of the locations of player deaths. The system also proactively designs alternatives to the level and class pairing, and presents them to the designer as suggestions that improve the predicted balance of the game. SuSketch offers a new way of integrating machine learning into mixed-initiative co-creation tools, as a surrogate of human play trained on a large corpus of artificial playtraces. A user study with 16 game developers indicated that the tool was easy to use, but also highlighted a need to make SuSketch more accessible and more explainable.

description: We explore the clustering of galaxy groups in the Galaxy and Mass Assembly (GAMA) survey to investigate the dependence of group bias and profile on separation scale and group mass. Due to the inherent uncertainty in estimating the group selection function, and hence the group auto-correlation function, we instead measure the projected galaxy--group cross-correlation function. We find that the group profile has a strong dependence on scale and group mass on scales $r_\bot \lesssim 1 h^{-1} \mathrm{Mpc}$. We also find evidence that the most massive groups live in extended, overdense, structures. In the first application of marked clustering statistics to groups, we find that group-mass marked clustering peaks on scales comparable to the typical group radius of $r_\bot \approx 0.5 h^{-1} \mathrm{Mpc}$. While massive galaxies are associated with massive groups, the marked statistics show no indication of galaxy mass segregation within groups. We show similar results from the IllustrisTNG simulations and the L-Galaxies model, although L-Galaxies shows an enhanced bias and galaxy mass dependence on small scales.

description: I consider anomalies in effective field theories (EFTs) of gauge fields coupled to fermions on an interval in AdS_5, and their holographic duals. The anomalies give rise to constraints on the consistent EFT description, which are stronger than the usual four-dimensional anomaly cancellation condition for the zero modes. Even though the anomalies occur on both boundaries of the interval, corresponding to both the UV and the IR of the holographic dual, they are nevertheless consistent with the non-renormalization of the anomaly and the 't Hooft matching condition. They give rise, in general, to a Wess-Zumino-Witten (WZW) term in the four-dimensional, low-energy effective action, whose form I compute. Finally I discuss the relevance to holographic models of electroweak symmetry breaking. I show that the so-called `minimal composite Higgs models' have a consistent EFT description without a WZW term. In contrast, a variant of an earlier model of Contino, Nomura, and Pomarol does have a WZW term.

Rakhmaninov's "Corelli" variations : new directions
Creators: name: McLean, Florence Anne
Publisher: name: University of British Columbia
Year: 2011

description: Only a few of RakJimaninov's compositions were popular with audiences during the lifetime of this Titan of the piano. Such youthful works as the Prelude in c# minor, op. 3, no. 2 and the Piano Concerto no. 2, op. 18 demonstrated only one facet of a creative process that evolved throughout his life. The purpose of this thesis, therefore, is to consider the extent of Rakhmaninov's stylistic evolution, especially the changes embodied in the large scale piano solo, Variations on a Theme of Corelli, written in the last decade of the composer's life. In the discussion of Rakhmaninov's lifelong stylistic development the author considers three distinct stages in his life as important landmarks. The first stage shows certain early influences upon the composer's creative powers, whether conscious, such as his acknowledged sensitivity to melody, or unconscious, such as medieval chant (Dies Irae), the sound of church bells, poetry and painting. The second addresses the question of the mixed legacy of Rakhmaninov's break with the past, when he left Russia in 1917 to re-settle in the United States the next year. On the one hand he never entirely broke his links with "Mother Russia," his fascination with the sounds of bells and chants, in his last decade of musical composition. For example, a comparison of the ancient Dies Irae theme with the La Folia tune that Corelli had used reveals striking similarities that Rakhmaninov undoubtedly found attractive, albeit unconsciously. On the other hand, he was inspired to seek a new conciseness of style and form in composition. The third stage relates to trends nurtured perhaps by his friendship with eminent string players and performers in America such as Fritz Kreisler. It is not surprising that Rakhmaninov's last two important works owe their themes to famous violin pieces: the Folia tune used by Arcangelo Corelli in the Corelli Variations and Paganini's well known 24th Caprice in the Paganini Rhapsody. These new directions in Rakhmaninov's music are most clearly present in the Corelli Variations, which are examined in terms of: (a) a new keyboard style; (b) string influenced variations; (c) elements of American jazz; and (d) a new clarity of structure. Finally, the writer examines similarities between the Corelli Variations and the Paganini Rhapsody that writers have sometimes touched upon.

description: Several thermodynamic measurements for the cobaltate superconductor, NaxCoO2.yH2O, have so far provided results inconsistent with each other. In order to solve the discrepancies, we microscopically calculate the temperature dependences of specific heat and superfluid density for this superconductor. We show that two distinct specific-heat data from Oeschler et al. and Jin et al. are reproduced, respectively, for the extended s-wave state and the p-wave state. Two different superfluid-density data are also reproduced for each case. These support our recent proposal of possible two different pairing states in this material. In addition, we discuss the experimentally proposed large residual Sommerfeld coefficient and extremely huge effective carrier mass.

description: The minimum spanning tree is used to study the process of market integration for a large group of national stock market indices. We show how the asset tree evolves over time and describe the dynamics of its normalized length, mean occupation layer, and single- and multiple-step linkage survival rates. Over the period studied, 1997-2006, the tree shows a tendency to become more compact. This implies that global equity markets are increasingly interrelated. The consequence for global investors is a potential reduction of the benefits of international portfolio diversification.

description: We consider the totally asymmetric simple exclusion process, a model in the KPZ universality class. We focus on the fluctuations of particle positions starting with certain deterministic initial conditions. For large time t, one has regions with constant and linearly decreasing density. The fluctuations on these two regions are given by the Airy_1 and Airy_2 processes, whose one-point distributions are the GOE and GUE Tracy-Widom distributions of random matrix theory. In this paper we analyze the transition region between these two regimes and obtain the transition process. Its one-point distribution is a new interpolation between GOE and GUE edge distributions.

description: Μέσα από την παρακάτω διπλωματική εργασία επιχειρείται η καταγραφή της υπάρχουσας κατάστασης του παλιού οικισμού της Αγίας Ρουμέλης, η αποτύπωση του χώρου, των αρχιτεκτονικών μορφών, καθώς και της προσβασιμότητας στον οικισμό. Ακόμη μελετώνται τα υλικά κατασκευής του οικισμού και συμπεριφορά
τους στο πέρασμα του χρόνου, ιδιαίτερα έπειτα από τη φυσική καταστροφή του οικισμού (υπερχείλιση ρέματος). Τέλος προτείνεται η αναβίωση και αποκατάσταση του οικισμού, ως αγροτουριστικός προορισμός.
Ειδικότερα η ερευνητική μέθοδος διακρίνεται σε τρία επίπεδα.
Στο πρώτο επίπεδο θα πραγματοποιηθεί η καταγραφή πληροφοριών για το πώς εξελίχθηκαν οι παραδοσιακοί οικισμοί στην Κρήτη και πώς αντιμετωπίστηκαν και αποκαταστάθηκαν αντίστοιχα παραδείγματα οικισμών.
Στο δεύτερο επίπεδο θα γίνει ιστορική και αρχιτεκτονική ανάλυση της παραδοσιακής σφακιανής αρχιτεκτονικής και ειδικότερα του οικισμού της Αγίας Ρουμέλης, καθώς και της εξέλιξής του στο χρόνο.
Επιχειρείται η αποτύπωση της κατάστασης του κτιριακού αποθέματος του παλιού οικισμού και η πλήρης αρχιτεκτονική αποτύπωση ενός συνόλου δύο κατοικιών σε μία από τις γειτονιές του. Επίσης μελετάται η κατάσταση και η συμπεριφορά των οικοδομικών υλικών (βότσαλα ποταμού ,ασβεστοκονιάματα) των κατοικιών στο πέρασμα του χρόνου.
Στο τρίτο επίπεδο προτείνεται η αποκατάσταση των παραπάνω κατοικιών και εν γενεί του συνόλου του οικισμού στο πλαίσιο λειτουργίας ενός συνεταιρισμού, με σκοπό τη δημιουργία πολιτιστικού και φυσιολατρικού δικτύου σύνδεσης με το Δρυμό της Σαμαριάς και την ευρύτερη περιοχή.
Στόχος της εργασίας είναι η αποκατάσταση του παλιού οικισμού, σύμφωνα με τις αρχικές αρχιτεκτονικές μορφές και υλικά και η αρμονική ένταξή του σε ένα ενιαίο οικοτουριστικό σύνολο.
Non-perturbative QCD Effects and the Top Mass at the Tevatron

description: We present a new, universally applicable toy model of colour reconnections in hadronic final states. The model is based on hadronising strings and has one free parameter. We next present an implementation of this model in the Pythia event generator and provide several parameter sets ("tunes"), constrained by fits to Tevatron minimum-bias data. Finally, we consider the sensitivity of a simplified top mass analysis to these effects, in exclusive semi-leptonic top events at the Tevatron. A first attempt at isolating the genuine non-perturbative effects gives an estimate of order delta(m_top) ~ 0.5 GeV from non-perturbative uncertainties, and a further delta(m_top) ~ 1 GeV from shower effects.

description: Calibrating the strength of the light-matter interaction is an important experimental task in quantum information and quantum state engineering protocols. The strength of the off-resonant light-matter interaction in multi-atom spin oscillators can be characterized by the coupling rate $Γ_\text{S}$. Here we utilize the Coherently Induced Faraday Rotation (CIFAR) signal for determining the coupling rate. The method is suited for both continuous and pulsed readout of the spin oscillator, relying only on applying a known polarization modulation to the probe laser beam and detecting a known optical polarization component. Importantly, the method does not require changes to the optical and magnetic fields performing the state preparation and probing. The CIFAR signal is also independent of the probe beam photo-detection quantum efficiency, and allows direct extraction of other parameters of the interaction, such as the tensor coupling $ζ_\text{S}$, and the damping rate $γ_\text{S}$. We verify this method in the continuous wave regime, probing a strongly coupled spin oscillator prepared in a warm cesium atomic vapour.

Overlap lattice fermion in a gravitational field

description: We construct a lattice Dirac operator of overlap type that describes the propagation of a Dirac fermion in an external gravitational field. The local Lorentz symmetry is manifestly realized as a lattice gauge symmetry, while it is believed that the general coordinate invariance is restored only in the continuum limit. Our doubler-free Dirac operator satisfies the conventional Ginsparg-Wilson relation and possesses gamma_5 hermiticity with respect to the inner product, which is suggested by the general coordinate invariance. The lattice index theorem in the presence of a gravitational field holds, and the classical continuum limit of the index density reproduces the Dirac genus. Reduction to a single Majorana fermion is possible for 8k+2 and 8k+4 dimensions, but not for 8k dimensions, which is consistent with the existence of the global gravitational/gauge anomalies in 8k dimensions. Other Lorentz representations, such as the spinor-vector and the bi-spinor representations, can also be treated. Matter fields with a definite chirality (with respect to the lattice-modified chiral matrix) are briefly considered.

description: LINAC 4 is a normal conducting H- structure proposed to intensify the proton flux currently available for the CERN accelerator chain. This linac is designed to accelerate a 65 mA beam up to 160 MeV to be injected into the CERN Proton Synchrotron Booster. The acceleration is performed up to 3 MeV by a Radio-Frequency Quadrupole resonating at 352 MHz followed by a serie of two drift tube systems (conventional Alvarez and Cell Coupled Drift Tube Linac) boosting the beam up to 90 MeV at 352 MHz and finished by a Side Coupled Linac at 704 MHz. Beam dynamics was studied and optimized performing end-to-end simulations. Robustness of this design was verified by modelling machine errors. This paper presents the results of this error study.

description: This paper is the third in a series whose goal is to develop a fundamentally new way of viewing theories of physics. Our basic contention is that constructing a theory of physics is equivalent to finding a representation in a topos of a certain formal language that is attached to the system. In paper II, we studied the topos representations of the propositional language PL(S) for the case of quantum theory, and in the present paper we do the same thing for the, more extensive, local language L(S). One of the main achievements is to find a topos representation for self-adjoint operators. This involves showing that, for any physical quantity A, there is an arrow $\breveδ^o(A):\Sig\map\SR$, where $\SR$ is the quantity-value object for this theory. The construction of $\breveδ^o(A)$ is an extension of the daseinisation of projection operators that was discussed in paper II. The object $\SR$ is a monoid-object only in the topos, $τ_ϕ$, of the theory, and to enhance the applicability of the formalism, we apply to $\SR$ a topos analogue of the Grothendieck extension of a monoid to a group. The resulting object, $\kSR$, is an abelian group-object in $τ_ϕ$. We also discuss another candidate, $\PR{\mathR}$, for the quantity-value object. In this presheaf, both inner and outer daseinisation are used in a symmetric way. Finally, there is a brief discussion of the role of unitary operators in the quantum topos scheme.
