description: We investigate theoretically the bifurcation scenario for colloidal suspensions subject to a vertical temperature gradient taking into account the effect of sedimentation. In contrast to molecular binary mixtures, here the thermal relaxation time is much shorter than that for concentration fluctuations. This allows for differently prepared ground states, where a concentration profile due to sedimentation and/or the Soret effect has been established or not. This gives rise to different linear instability behaviors, which are manifest in the temporal evolution into the final, generally stationary convective state. In a certain range above a rather high barometric number there is a coexistence between the quiescent state and the stationary convective one, allowing for a hysteretic scenario.

description: Spaceborne gravitational-wave observatories utilize a post-processing technique known as time-delay interferometry (TDI) to reduce the otherwise overwhelming laser frequency noise by around eight orders of magnitude. While, in its traditional form, TDI considers the spacecraft as point masses, recent studies have enhanced this simplified scenario by incorporating more realistic metrology chain models, which include onboard optical, electronic, and digital delays. These studies have updated the TDI algorithm to include onboard delays obtained from pre-launch and in-flight calibrations. Conversely, the processing scheme presented in this article naturally treats onboard delays as part of the TDI combinations: instead of having separate calibration stages, it directly expresses all delays appearing in the algorithm in terms of onboard measurements, especially pseudo-random-noise ranging (PRNR) measurements. The only onboard delays that need to be corrected in our processing scheme are PRNR delays in the digital domain, which are determined by commandable digital-signal-processing parameters; hence, they can be easily managed in post-processing. Furthermore, our processing scheme does not require a prior interspacecraft clock synchronization, and it automatically corrects for potential relative drifts between the clocks driving local phase measurement systems. The proposed observable-based processing scheme significantly strengthens the bond between TDI and the real metrology system.

description: We introduce a fast implementation of the pivot algorithm for self-avoiding walks, which we use to obtain large samples of walks on the cubic lattice of up to $33 \times 10^6$ steps. Consequently the critical exponent $ν$ for three-dimensional self-avoiding walks is determined to great accuracy; the final estimate is $ν=0.587597(7)$. The method can be adapted to other models of polymers with short-range interactions, on the lattice or in the continuum.

Magnification factors for hingeless arches.
Creators: name: Pelton, Thomas Edward
Publisher: name: University of British Columbia
Year: 2012

description: This thesis presents a simple method for the determination of bending moments in flexible symmetrical hingeless arches. The deflection theory bending moments are obtained by multiplying elastic theory bending moments by predetermined magnification factors. The problem was to provide magnification factors for all cases of loading on a wide range of flexible symmetrical hingeless arches. By studying the differential equation a modified method of superposition was developed. Therefore, it was only necessary to determine magnification factors for a concentrated load at a number of positions along the arch axis. A convenient set of coordinates for the magnification factor was determined by dimensional analysis. Finally, an electronic computer was used to calculate the required magnification factors by a numerical method. Tables of magnification factors are presented for symmetrical parabolic hingeless arches. Magnification factors are given for rise to span ratios of 1/8, 1/6, 1/4, and 1/3 ; for constant and variable moment of inertia; and for values of [formula omitted]from 0 to 7, where H = the total horizontal thrust, L = the span, EIa = the average flexural rigidity.

description: We examine the superfluid phase of a hard-core boson model with nearest-neighbor exchange J and four-particle ring-exchange K at half-filling on the square lattice. At zero temperature we find that the superfluid in the pure-J model is quickly destroyed by the inclusion of negative-K ring-exchange interactions, favoring a state with a (pi,pi) ordering wavevector. Minimization of the mean-field energy suggests that a supersolid state with coexisting superfluidity, charge-density wave, and valence-bond-like order is formed. We also study the behavior of the finite-T Kosterlitz-Thouless phase transition in the superfluid phase, by forcing the Nelson-Kosterlitz universal jump condition on the finite-T spin wave superfluid density. Away from the pure J point, T_{KT} decreases rapidly for negative K, while for positive K, T_{KT} reaches a maximum at some K \neq 0 in agreement with recent quantum Monte Carlo simulations.

Analysis of flexible hingeless arch by an influence line method.
Creators: name: Lee, Richard Way Mah
Publisher: name: University of British Columbia
Year: 2012

description: An influence line method for the analysis of flexible hingeless arch by the deflection theory is presented in this thesis. To facilitate the work, tables of dimensionless magni fication factors are provided. Prom these tables, influence lines taking into account the flexibility of the arch may be readily drawn and used very much in the ordinary way. The flexibility of the arch was conveniently measured by a dimensionless ratio, [ equation omitted ], and called the stiffness factor of the arch. The tables are for parabolic hingeless arches having rise ratios of 1/8,1/6,1/4,1/3, with constant EI or a prescribed variable EI. Values are given for β = 3 and 5 with some for β = 7. Also the tables contain magnification factors for maximum moments at eleven points in the arch, when the arch is loaded with a uniform load. Although the given tables are good only for parabolic hingeless arches with constant EI or a prescribed variation in EI, the tables may be reasonably extended to other hingeless arches whose shapes are not too different from a parabola and to a wide variety of variation in moment of inertia, provided these variations are not unrealistic. The possibility of using superposition in the deflection theory is based on the fact that calculations showed the horizontal thrust acting on the arch was approximately the same either by the deflection theory or the elastic theory. Because of this, the horizontal thrust becomes independent of deflection and the differential equation for bending of an arch is linear. Thus superposition may be used. The differential equation was hot convenient for calculation. Instead, the solutions in the tables were calculated by a numerical procedure of successive approximations, using the conjugate beam concept. This procedure was conveniently programmed for an electronic computer, the ALWAC III E, at the University of British Columbia. In the first cycle of approximation, the programme assumed the horizontal and vertical deflections were zero. This represented the elastic theory analysis. In subsequent cycles, the deflected shape of the arch from previous analysis was assumed. Successive approximation as such led to a solution based on the deflection theory. Three numerical examples shown in this thesis indicated that the error introduced by the linearized deflection theory was small, and the influence line method may be used for analysis of flexible arches.
DISC1 is needed for the organization of cellular components at the immunological synapse.

description: T-cells carry out their immune functions through receptor-based recognition and adhesion to target cells. The cell-cell junction that is created from this connection is known as the immunological synapse (IS); a cellular structure composed of organized receptor clusters. Polymerization of F-actin at the synapse has been cited as a necessary step in the continuous activation and flow of T-cell receptors (TCR) towards the center of the synapse and activation of the integrin, Lymphocyte Function Associated Antigen 1 (LFA-1). These processes help T-cells form stable and specific connections with their cognate Antigen Presenting Cells (APCs). It has been previously shown that Disrupted in Schizophrenia 1 (DISC1), a protein with connections to actin-based signaling in neurons, is expressed in T-cells. Through immunofluorescence techniques and CRISPR-Cas9 knockout experiments, we have established that knocking out DISC1 inhibits the polymerization of actin filaments at the synapse. We also identified the actin-binding protein Girdin as a potential effector to actin-based functions of DISC1 at the synapse. We establish that Girdin is expressed at the immunological synapse and that Girdin knockout cell lines showed no detectable actin at the synapse, similar to DISC1 knockouts. Using immunoprecipitation techniques, we also show that DISC1 forms a complex with Girdin in Jurkat cells. Together, these experiments suggest that DISC1 plays a role in actin signaling at the synapse through interactions with Girdin.
Viscoelastic subdiffusion: from anomalous to normal

description: We study viscoelastic subdiffusion in bistable and periodic potentials within the Generalized Langevin Equation approach. Our results justify the (ultra)slow fluctuating rate view of the corresponding bistable non-Markovian dynamics which displays bursting and anti-correlation of the residence times in two potential wells. The transition kinetics is asymptotically stretched-exponential when the potential barrier $V_0$ several times exceeds thermal energy $k_BT$ ($V_0\sim 2 - 10 k_BT$) and it cannot be described by the non-Markovian rate theory (NMRT). The well-known NMRT result approximates, however, ever better with the increasing barrier height, the most probable logarithm of the residence times. Moreover, the rate description is gradually restored when the barrier height exceeds a fuzzy borderline which depends on the power law exponent of free subdiffusion $α$. Such a potential-free subdiffusion is ergodic. Surprisingly, in periodic potentials it is not sensitive to the barrier height in the long time asymptotic limit. However, the transient to this asymptotic regime is extremally slow and it does profoundly depend on the barrier height. The time-scale of such subdiffusion can exceed the mean residence time in a potential well, or in a finite spatial domain by many orders of magnitude. All these features are in sharp contrast with an alternative subdiffusion mechanism involving jumps among traps with the divergent mean residence time in these traps.

Theory of agent-based market models with controlled levels of greed and anxiety

description: We use generating functional analysis to study minority-game type market models with generalized strategy valuation updates that control the psychology of agents' actions. The agents' choice between trend following and contrarian trading, and their vigor in each, depends on the overall state of the market. Even in `fake history' models, the theory now involves an effective overall bid process (coupled to the effective agent process) which can exhibit profound remanence effects and new phase transitions. For some models the bid process can be solved directly, others require Maxwell-construction type approximations.

description: Lake Victoria lies in the heart of the Murray Darling Basin. During the height of the Last Glacial Maximum (LGM) up to 3 metres of wind-blown sand and dust was deposited along the top of the lunette on the eastern shore of Lake Victoria, creating an unparalleled environment for preserving archaeological remains. Aboriginal shell middens and faunal remains in stratigraphic context provide a record of human adaptation to the extreme climate variability which prevailed between 17,000 and 14,500 BP. Fieldwork at Lake Victoria centred on Gills Gully, a 1 sq km area in the central, highest area of the Lake Victoria lunette. Six LGM dates were obtained from Velesunio shell recovered from middens within this area and a stratigraphic sequence was developed for the upper ten metres of the lunette. Several shell middens were excavated in order to investigate environmental conditions and Aboriginal adaptations during the height of the LGM. LGM middens had been so gently buried by settling dust that ash, tiny bone fragments and delicate dots of scarlet ochre were preserved, and tiny air bubbles can be seen in the dusty grey overburden. Middens were composed of closely packed freshwater mussel shell interspersed with fine ash, charcoal and finely divided ochre. Remains of small macropods (hare wallaby), yabby, lizard, frog and more rarely fish and bird were present - average length of faunal fragments was less than 6 mm. A polished bone point was recovered from a shell lens dated to 16,170+/- 190 (ANU 2876). With the exception of a tiny fragment of sandstone no stone artefacts were recovered from Pleistocene middens. Between 16,000 and 15,000 BP there was a marked change in the pattern of human occupation around Lake Victoria. Chemical and physical analysis of the midden shell and the overburden shows that that the increase in midden density cannot be explained by site preservation factors. By 15,000 years earlier patterns of large, scattered charcoal-rich occupation deposits had been replaced by smaller, more numerous shell middens around 1 metre in diameter, in places so thickly clustered as to form overlapping lenses of well preserved compacted freshwater shells up to 60 cm thick, a much more intense pattern of exploitation. During the last phases of the Last Glacial Maximum Lake Victoria was an oasis an increasingly desiccated late Pleistocene landscape. It is likely that local population increased at this time and that people turned increasingly to freshwater mussels for sustenance.
Light flavor baryon spectrum with higher order hyperfine interactions

Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the spectrum of light flavor baryons in a quark-model framework by taking into account the order $\mathrm{O}(α_s^2)$ hyperfine interactions due to two-gluon exchange between quarks. The calculated spectrum agree better with the experimental data than the results from hyperfine interactions with only one-gluon exchange. It is also shown that two-gluon exchange hyperfine interactions bring a significantly improved correction to the Gell-Mann--Okubo mass formula. Two-gluon exchange corrections on baryon excitations (including negative parity baryons) are also briefly discussed.

description: The Limits of Acceptability approach has been demonstrated to be an effective conditioning tool due to its capacity to consider epistemic uncertainty. However, its application faces two challenges—the low efficiency when random sampling is used and the difficulty in setting limits prior to calibration. Here an algorithm DREAM(LoAX) was developed and added to GLUE framework. As an extension of DREAM(LoA) of Vrugt and Beven (2018), https://doi.org/10.1016/j.jhydrol.2018.02.026, it evaluates model performance based on limit boundaries, thus inherits the merits of the GLUE framework (explicit consideration of epistemic errors). Moreover, the importance of initial choice of limits is strongly reduced by allowing iterative evolution of limits based on historical model performance. By testing a series of examples (including a high‐dimensional numeric example, a single‐objective hydrological example, and a multi‐objective hydrological example) with or without error‐free assumption using synthetic or real observations, the search capacity of DREAM(LoAX) to locate acceptable models is demonstrated. The algorithm also shows comparable efficiency to DREAM and DREAM(LoA). More importantly, it provides real‐time diagnostic information regarding when (at which timestep), where (for which objective), and how (to which direction and to which extent) the model fails when uncertainty is pronounced, allowing potential uncertainty sources in the data or flaws in the model structure to be identified. In this context, DREAM(LoAX) is not only a useful conditioning tool, but also a diagnostic and learning tool for development of improved modeling.

Influence of structural disorder and large-scale geometric fluctuations on the Coherent Transport of Metallic Junctions and Molecular Wires

description: Structural disorder is present in almost all experimental measurements of electronic transport through single molecules or molecular wires. To assess its influence on the conductance is computationally demanding, because a large number of conformations must be considered. Here we analyze an approximate recursive layer Green function approach for the ballistic transport through quasi one-dimensional nano-junctions. We find a rapid convergence of the method with its control parameter, the layer thickness, and good agreement with existing experimental and theoretical data. Because the computational effort rises only linearly with system size, this method permits treatment of very large systems. We investigate the conductance of gold- and silver wires of different sizes and conformations. For weak electrode disorder and imperfect coupling between electrode and wire we find conductance variations of approximately 20%. Overall we find the conductance of silver junctions well described by the immediate vicinity of narrowest point in the junction, a result that may explain the observation of well-conserved conductance plateaus in recent experiments on silver junctions. In an application to flexible oligophene wires, we find that strongly distorted conformations that are sterically forbidden at zero temperature, contribute significantly to the observed average zero-bias conductance of the molecular wire.

description: Matrix completion plays an important role in machine learning and signal processing, with applications ranging from recommender systems to image inpainting. Many approaches have been considered to solve the problem and some offer computationally efficient solutions. In particular, a highly-efficient random coordinate descent approach reduces the per-epoch computation dramatically. This paper is concerned with further improvement of computational efficiency to expand the range of problem sizes and conditions that can be solved. Momentum acceleration is a well-known method to improve the efficiency of iterative algorithms, but applying it to random coordinate descent methods without increasing the computational complexity is non-trivial. To address this challenge, we introduce a momentum-accelerated randomized coordinate descent for matrix completion approach that does not increase computational complexity by accelerating at the level of epochs. Additionally, we propose an analysis-driven, tuning-free method for step size selection. To that end, we offer a convergence rate analysis for the algorithm. Using numerical evaluations, we demonstrate the competitiveness of the method and verify the theoretical analysis.

La sonda Cassini ha esplorato lo spazio attorno a Titano rilevando fotoelettroni, emessi dalla sua ionosfera anche a grande distanza dalla sua superficie, che trascinano particelle di idrocarburi e nitrili nella zona dell'atmosfera irraggiata dal Sole, dando luogo a un diffuso vento polare
The validity of the simplified limit design method for the design of structures.
Creators: name: Parkhill, Douglas Leonard
Publisher: name: University of British Columbia

description: Practice in the field of limit design has tended to place certain restrictions on structural loading patterns in order to simplify the calculations involved in the limit design procedure. The loads considered in this simplified approach are assumed to either remain constant and fixed, or if they vary then this is to be in such a manner that their magnitudes stand in a constant relationship one to the other. Actual structural loadings seldom satisfy these restrictive conditions and the question naturally arises as to whether or not this simplified limit design procedure is valid for general use in practical design problems in which external loads may be wholly independent in their individual actions. This question is investigated in the present paper through the examination of several practical forms of structure which portray the more adverse conditions of independent and variable loading to be met in practice. These structures are, respectively, single and double bay gable bents of lightweight construction, and two forms of multispan bridge girders. The study indicates that all of these structures are able to support the ultimate loads predicted by the simplified limit design method; the actual ultimate loads exceeding the predicted values by up to twenty percent. It is concluded that structural failure in practice can always be expected to occur within acceptable limits of the ultimate load capacity as predicted by the simplified method.
