description: The Torsion Anomalous Conjecture states that an irreducible variety $V$ embedded in a semi-abelian variety contains only finitely many maximal $V$-torsion anomalous varieties. In this paper we consider an irreducible variety embedded in a product of elliptic curves. Our main result provides a totally explicit bound for the Néron-Tate height of all maximal $V$-torsion anomalous points of relative codimension one, in the non CM case, and an analogous effective result in the CM case. As an application, we obtain the finiteness of such points. In addition, we deduce some new explicit results in the context of the effective Mordell-Lang Conjecture; in particular we bound the Néron-Tate height of the rational points of an explicit family of curves of increasing genus.

Colliding Wave Solutions, Duality, and Diagonal Embedding of General Relativity in Two-Dimensional Heterotic String Theory

Year: 1995
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The non-linear sigma model of the dimensionally reduced Einstein (-Maxwell) theory is diagonally embedded into that of the two-dimensional heterotic string theory. Consequently, the embedded string backgrounds satisfy the (electro-magnetic) Ernst equation. In the pure Einstein theory, the Matzner-Misner SL(2,{\bf R}) transformation can be viewed as a change of conformal structure of the compactified flat two-torus, and in particular its integral subgroup SL(2,{\bf Z}) acts as the modular transformation. The Ehlers SL(2,{\bf R}) and SL(2,{\bf Z}) similarly act on another torus whose conformal structure is induced through the Kramer-Neugebauer involution. Either of the Matzner-Misner and the Ehlers SL(2,{\bf Z}) can be embedded to a special T-duality, and if the former is chosen, then the Ehlers SL(2,{\bf Z}) is shown to act as the S-duality on the four-dimensional sector. As an application we obtain some new colliding string wave solutions by using this embedding as well as the inverse scattering method.

description: We investigate the number of straight lines contained in a K3 quartic surface \(X\) defined over an algebraically closed field of characteristic 3. We prove that if \(X\) contains 112 lines, then \(X\) is projectively equivalent to the Fermat quartic surface; otherwise, \(X\) contains at most 67 lines. We improve this bound to 58 if \(X\) contains a star (ie four distinct lines intersecting at a smooth point of \(X\)). Explicit equations of three 1-dimensional families of smooth quartic surfaces with 58 lines, and of a quartic surface with 8 singular points and 48 lines are provided.

description: Randomized algorithms provide solutions to two ubiquitous problems: (1) the distributed calculation of a principal component analysis or singular value decomposition of a highly rectangular matrix, and (2) the distributed calculation of a low-rank approximation (in the form of a singular value decomposition) to an arbitrary matrix. Carefully honed algorithms yield results that are uniformly superior to those of the stock, deterministic implementations in Spark (the popular platform for distributed computation); in particular, whereas the stock software will without warning return left singular vectors that are far from numerically orthonormal, a significantly burnished randomized implementation generates left singular vectors that are numerically orthonormal to nearly the machine precision.

description: On February 20, 1976, the Museum of Northern Arizona, at the request of the Salt River Project, conducted an archaeological survey of a proposed access road right-of-way, an observation well and a production well in the Concho Well Field, five miles north of Concho, Arizona. During the survey, one archaeological site was encountered in the proposed access road right-of-way. On March 7, 1976, the site was collected and recorded. This action constitutes mitigation of adverse effects for this site and archaeological clearance is therefore recommended for the proposed access and observation and production well.
Optimal control of differential-algebraic equations from an ordinary differential equation perspective

description: We study the Optimal Control Problem (OCP) for regular linear differential-algebraic systems (DAEs). To this end, we introduce the input index, which allows, on the one hand, to characterize the space of consistent initial values in terms of a Kalman-like matrix and, on the other hand, the necessary smoothness properties of the control. The latter is essential to make the problem accessible from a numerical point of view. Moreover, we derive an augmented system as the key to analyze the OCP with tools well-known from optimal control of ordinary differential equations. The new concepts of the input index and the augmented system provide easily checkable sufficient conditions which ensure that the stage costs are consistent with the differential-algebraic system.

description: The subject of this report is the description of the site and environs of a proposed short transmission line corridor that will tie the San Juan Generating Station to existing lines to Albuquerque for delivery of power to that city and to the Four Corners plant thereby providing transmission line backup for Albuquerque and Tucson and improving stability of the electrical system. The requirements for such a report as this come from the National Environmental Policy Act through its implementation by rights-of-way regulations set up by the Department of the Interior. Any of the several routes considered as alternatives cross both Bureau of Land Management and Bureau of Indian Affairs administered lands. Consequently, the proposed transmission line comes under the permit system of the Department of the Interior and the applicant must prepare an environmental report on the proposed action. Because of interest in water rights, the Bureau of Reclamation was assigned the task of preparing an Environmental Statement for the San Juan Generating Station. Since, through a letter by the Undersecretary of the Interior dated June 28, 1971, such statements must include the associated transmission lines, the Bureau of Reclamation was assigned as lead agency on the transmission line project. The corridor will contain two 345KV lines about nine miles long mounted on individual wooden structures of a kind in common use in that area. These structures are resistant to the climate and are relatively trouble-free and inexpensive compared to steel aluminum structures. The electric current is carried by steel reinforced aluminum cable. Construction of the line will emphasize care in stringing the conductor and setting the structures to minimize impact on the environment. The proposed transmission lines will be built in what has been called the Northern Desert of New Mexico, a particularly arid region for its elevation.

Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Supergravity solutions related to large N SU(N) pure gauge theories with eight supercharges have recently been shown to give rise to an ``enhancon'', a new type of hypersurface made of D-branes. We show that enhancons also arise in similar situations pertaining to SO(2N+1), USp(2N) and SO(2N) gauge theories, using orientifolds. Enhancons therefore appear to come in types A, B, C, and D. The latter three differ globally from type A by having an extra Z_2 identification, and are distinguished locally by their subleading behaviour in large N. We focus mainly on 2+1 dimensional gauge theory, where a relation to M-theory and the Atiyah-Hitchin and Taub-NUT manifolds enables the construction of the smooth supergravity solution and the study of some of the 1/N corrections. The role of the enhancon in eleven dimensional supergravity is also uncovered. There is a close relation to certain multi-monopole moduli space problems.

More concretely, we give a lower bound on the first Betti number of this subgroup, based on the number and degree of a certain type of vertices, which we call deep. We then use combinatorial methods to analyze the average value of this Betti number, in terms of the size of the defining tree.
Uninhabited aircraft design optimised for close formation air-refuelling flight
Creators: name: Nilsuwan, Sma
Publisher: name: Imperial College London
Year: 2010

description: Uninhabited combat aerial vehicles (UCAVs) are intended for carrying out high-risk combat missions with a high degree of precision, effectiveness and efficiency and without endangering pilots’ lives. An air refuelling system for UCAVs could bring out their full potential in wartime action, by extending their range capability and increasing their airborne time. Hence, the main aim of this PhD research programme was to develop a design and optimisation methodology for an innovative concept consisting of a large uninhabited tanker and a number of UCAVs flying in a close formation, with an optimised and fully autonomous air refuelling capability. The close formation flight of this tanker and UCAVs combination provides aerodynamic benefits which together with an optimised air-to-air refuelling sequence will result in a significantly extended combat radius and capability without unnecessarily compromising the UCAVs’ physical size. With a stealth design approach, the proposed combination could fly directly to a faraway destination without any intermediate stops, hence minimizing any risk of detection, with significant fuel and time savings. To fully exploit the potential advantages the above combination, both the autonomous tanker and the UCAV concepts have been designed through specially developed and separate synthesis methodologies and each aircraft was subsequently optimised for its respective operational role. An investigation into formation flight aerodynamics has also been conducted. A method for evaluating the associated aerodynamic benefits has been developed using a modified vortex-lattice approach, to automatically locate an optimal formation position for each aircraft in flight. A further method has also been developed to optimise the air refuelling sequence of the UCAVs by utilising the design synthesis and formation flight results aiming to maximise a range objective function. The above design synthesis and optimisation methodologies have all been integrated into an automated program written in Visual Basic.NET, featuring Graphical User Interfaces for simpler, faster and repetitive implementation.
Exact Solution of the O(n) Model on a Random Lattice

Year: 1995
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We present an exact solution of the $O(n)$ model on a random lattice. The coupling constant space of our model is parametrized in terms of a set of moment variables and the same type of universality with respect to the potential as observed for the one-matrix model is found. In addition we find a large degree of universality with respect to $n$; namely for $n\in ]-2,2[$ the solution can be presented in a form which is valid not only for any potential, but also for any $n$ (not necessarily rational). The cases $n=\pm 2$ are treated separately. We give explicit expressions for the genus zero contribution to the one- and two-loop correlators as well as for the genus one contribution to the one-loop correlator and the free energy. It is shown how one can obtain from these results any multi-loop correlator and the free energy to any genus and the structure of the higher genera contributions is described. Furthermore we describe how the calculation of the higher genera contributions can be pursued in the scaling limit.

description: Transverse quasilinear relaxation of the cyclotron-Cherenkov instability in the inhomogeneous magnetic field of pulsar magnetospheres is considered. We find quasilinear states in which the kinetic cyclotron-Cherenkov instability of a beam propagating through strongly magnetized pair plasma is saturated by the force arising in the inhomogeneous field due to the conservation of the adiabatic invariant. The resulting wave intensities generally have nonpower law frequency dependence, but in a broad frequency range can be well approximated by the power law with the spectral index -2. The emergent spectra and fluxes are consistent with the one observed from pulsars.

Bimetallic Complexes as Catalysts for the Copolymerisation of Epoxides and CO2
Creators: name: Kember, Michael R.
Publisher: name: Imperial College London
Year: 2010

description: A series of novel macrocyclic ligands bearing amine and phenol donor atoms was synthesised, with differing substituents on the aromatic ring. These ligands were designed to allow incorporation of two metal centres in proximity within a flexible macrocyclic cavity. From these ligands, three new bimetallic zinc acetate complexes were produced. These complexes were the most active catalysts for the copolymerisation of CO2 and cyclohexene oxide at 1 atm CO2 pressure, which could significantly reduce the energy cost of plastic production. The catalysts produced poly(cyclohexene carbonate) with near-perfect CO2 incorporation. Variation of reaction conditions showed the catalysts were tolerant of water/oxygen, and active under low loadings. Trimetallic complexes were also synthesised, showing an externally bound zinc site to exhibit reduced activity. The copolymers produced had low molecular weights (<20,000 g/mol), probably due to chain transfer reactions. Replacement of zinc with cobalt(II) increased the activity tenfold, probably due to the more nucleophilic cobalt-carbonate bonds. Oxidation of the Co(II)/Co(II) complex produced a mixed valence Co(II)/Co(III) complex; characterised by X-ray crystallography, UV-Vis spectroscopy and magnetic measurements. The complexes showed extremely high activity under 1 atm CO2, furthermore, at 10 atm, an activity similar to the best catalysts was observed. Both ionic and neutral cobalt(II) halide complexes were synthesised. These complexes showed slightly higher molecular weights, but lower activities. By coordinating strong nucleophilic donors (such as 4-dimethylaminopyridine) to the metal centre, the catalytic activity was significantly reduced, a result which led to the proposal of a bimetallic mechanism. The use of other epoxides (e.g. propylene oxide and styrene oxide) in the copolymerisation was attempted. However, the catalysts were inactive for copolymerisation with these epoxides. The terpolymerisation of cyclohexene oxide, CO2 and propylene oxide showed poor control and activity. The block copolymerisation of PCHC with lactide was also investigated producing, tri-block copolymers.

description: Failing to distinguish between a sheepdog and a skyscraper should be worse and penalized more than failing to distinguish between a sheepdog and a poodle; after all, sheepdogs and poodles are both breeds of dogs. However, existing metrics of failure (so-called "loss" or "win") used in textual or visual classification/recognition via neural networks seldom leverage a-priori information, such as a sheepdog being more similar to a poodle than to a skyscraper. We define a metric that, inter alia, can penalize failure to distinguish between a sheepdog and a skyscraper more than failure to distinguish between a sheepdog and a poodle. Unlike previously employed possibilities, this metric is based on an ultrametric tree associated with any given tree organization into a semantically meaningful hierarchy of a classifier's classes. An ultrametric tree is a tree with a so-called ultrametric distance metric such that all leaves are at the same distance from the root. Unfortunately, extensive numerical experiments indicate that the standard practice of training neural networks via stochastic gradient descent with random starting points often drives down the hierarchical loss nearly as much when minimizing the standard cross-entropy loss as when trying to minimize the hierarchical loss directly. Thus, this hierarchical loss is unreliable as an objective for plain, randomly started stochastic gradient descent to minimize; the main value of the hierarchical loss may be merely as a meaningful metric of success of a classifier.

description: This report details the results of a cultural resources assessment of a 200 acre parcel of private land at the request of The Pollack/Ramras Companies. The parcel was examined for the presence of cultural resources by archaeologists Douglas R. Mitchell and Robert G. Haynes-Peterson, between August 24 and 31, 1993. The project was conducted in compliance with City of Mesa planning and zoning, which stipulates that a cultural resources inventory and assessment be implemented on land which is proposed for rezoning if it occurs in an area where the probability of cultural resources is high, as outlined by the City of Mesa and the Arizona State Historic Preservation Office. The area surveyed is located in T 1S, R7E in the southeast quarter of Section 20 (40 acres) and the southwest quarter of Section 21 (160 acres). A total of 200 acres was examined. The parcel is located west of the General Motors Desert Proving Ground and immediately north of Williams Air Force Base. It is at the intersection of the projected extensions of Ray Road and Hawes Road (Figure 1). One site and eighteen isolated occurrences (IOs) were recorded. The site, AZ U:10:74 (ASM), is not considered to contain information that would make it eligible for inclusion in the National Register of Historic Places. Neither are the IOs considered to be significant. Therefore, it is recommended that no further archaeological work be conducted within the parcel and that the project proceed.

description: Detection of high-redshift absorption in the optical spectra of quasars have provided a powerful tool to measure spatial and temporal variations of physical ``constants'' in the Universe. It is demonstrated that high sensitivity to the variation of the fine structure constant alpha can be obtained from a comparison of the spectra of heavy and light atoms (or molecules). We have performed calculations for the pair FeII and MgII for which accurate quasar and laboratory spectra are available. A possibility of $10^5$ times enhanced effects of the fundamental constants variation suitable for laboratory measurements is also discussed.

Regression-aware decompositions

description: Linear least-squares regression with a "design" matrix A approximates a given matrix B via minimization of the spectral- or Frobenius-norm discrepancy ||AX-B|| over every conformingly sized matrix X. Another popular approximation is low-rank approximation via principal component analysis (PCA) -- which is essentially singular value decomposition (SVD) -- or interpolative decomposition (ID). Classically, PCA/SVD and ID operate solely with the matrix B being approximated, not supervised by any auxiliary matrix A. However, linear least-squares regression models can inform the ID, yielding regression-aware ID. As a bonus, this provides an interpretation as regression-aware PCA for a kind of canonical correlation analysis between A and B. The regression-aware decompositions effectively enable supervision to inform classical dimensionality reduction, which classically has been totally unsupervised. The regression-aware decompositions reveal the structure inherent in B that is relevant to regression against A.

Millisecond oscillations in the bursting flux of SAX J1810.8-2609

description: SAX J1810.8-2609 is a faint X-ray transient, mostly known for its abnormally low quiescent thermal luminosity, which disagrees with standard cooling models. It is also one of a small sample of stars whose mass and radius have been estimated using spectral modeling of one of its thermonuclear bursts. Here we report the discovery of millisecond oscillations in a type I thermonuclear X-ray burst from SAX J1810.8-2609 observed by RXTE during the 2007 outburst. A strong signal (Leahy-normalized power of 71.5, 4.5e-9 chance of coincidence with a conservative estimate for the number of trials) was present at 531.8 Hz during the decay of one out of six bursts observed. Oscillations were detected for about 6 seconds, during which their frequency increased from 531.4 to 531.9 Hz in a manner similar to other burst oscillation sources. The millisecond oscillations discovered pinpoint the spin frequency of the neutron star, which is important for the spectral modeling, associated mass-radius inference, and understanding the evolutionary status and cooling behavior of the star. As of April 2018 the source is in outburst again, providing a fleeting opportunity to acquire new material for the burst oscillation searches.

description: This report presents the results of an archeological survey conducted on federal lands near Huerfano, New Mexico, by the Office of Contract Archeology, University of New Mexico. The survey, undertaken at the request of the Salt River Project, is a supplement to a cultural overview and 10% sample survey performed in the area the previous fall (Allen 1981). The purpose of the present project was to locate and document any cultural resources found on 48 drill pad locations and along any access routes. In addition, interviews were held with local residents to obtain permission to survey and to construct the drill holes and access roads, and to obtain data on site uses. The result of the survey was the recording of nine sites (one of which was recorded previously), thirteen localities, ten isolated occurrences, and one current cultural manifestation. Archeological clearance is recommended, since any potential drill locations and roads that might impinge upon cultural resources were relocated away from the resources during the survey.
Affine Lie Algebra Symmetry of Sine-Gordon Theory at Reflectionless Points

description: The quantum affine symmetry of the sine-Gordon theory at q^2 = 1, which occurs at the reflectionless points, is studied. Conserved currents that correspond to the closure of simple root generators are considered, and shown to be local. We argue that they satisfy the affine sl(2) algebra. Examples of these currents are explicitly constructed.
