description: We present results of micromagnetic simulations of thin ferromagnetic rings undergoing magnetization reversal. This geometry is one of few examples in micromagnetics in which the transition states have been found analytically in a 1D model. According to this model, at low fields and large ring sizes, the energetically preferred transition state is a localized magnetization fluctuation (instanton saddle). At high fields and small ring size, the preferred saddle state is a uniformly rotated magnetization (constant saddle). In the first part of this paper, we use numerical micromagnetic simulations to test these predictions of the 1D analytical model for more realistic situations, including a variety of ring radii, annular widths and magnetic fields. The predicted activation energies for magnetization reversal are found to be in close agreement with numerical results, even for rings with a large annular width where the 1D approximation would be expected to break down. We find that this approximation breaks down only when the ring's annular width exceeds its radius. In the second part, we present new metastable states found in the large radius limit and discuss how they provide a more complete understanding of the energy landscape of magnetic nanorings.

description: This paper proposes a new robust control method for quantum systems with uncertainties involving sliding mode control (SMC). Sliding mode control is a widely used approach in classical control theory and industrial applications. We show that SMC is also a useful method for robust control of quantum systems. In this paper, we define two specific classes of sliding modes (i.e., eigenstates and state subspaces) and propose two novel methods combining unitary control and periodic projective measurements for the design of quantum sliding mode control systems. Two examples including a two-level system and a three-level system are presented to demonstrate the proposed SMC method. One of main features of the proposed method is that the designed control laws can guarantee desired control performance in the presence of uncertainties in the system Hamiltonian. This sliding mode control approach provides a useful control theoretic tool for robust quantum information processing with uncertainties.

Investigation of the mechanism of failure of neat cement and mortar specimens
Creators: name: Urruela, Juan Francisco
Publisher: name: University of British Columbia
Year: 2012

description: The problem of the investigation of the mechanism of failure in compression of neat cement and mortar specimens is considered in this thesis. The study was made on two hundred specimens of cement paste and mortar, of which approximately one half were tension briquets and the other half compression cylinders. The underlying theory which led to this study was that failure in compression in specimens with aggregate (mortar and concrete) is due to the wedging action of the particles of aggregate within the matrix of cement paste. Steam-curing was used to avoid delay in the hardening of cement. It was found that the cement used was of the type which continues hardening after being steam-cured. The importance of having the specimens at a constant temperature throughout their mass and at room temperature when the tests were performed was realized. An investigation of the effect of end conditions on test cylinders in compression was conducted. It is considered that the confined rubber end conditions used were an improvement on testing with lubricated ends only. Observations were made on the effect of the bursting action of water in compression tests of moist specimens. A study of the effect of stress concentration around voids was made on tension specimens. Compression specimens made of neat cement, mortar and cement with inclusions in the form of balls were studied. Inclusions were placed in cement cylinders to imitate the action of the aggregate in mortar and concrete specimens. Tests on compression specimens with inclusions were useful in the interpretation of results of tests on neat cement and mortar cylinders and in the study of the stress-strain curves. Transverse bending tests of cylinders were made with the purpose of investigating the presence of transverse cracks formed in the cylinders as a consequence of the application of compressive loads. They did not provide a good method of investigation but were very useful in that they were an aid to realizing the effect of the horizontal cracks in the stress-strain curves.

description: We present a comprehensive study of rotation, disk and accretion signatures for 144 T Tauri stars in the young (~2 Myr old) Chamaeleon I and Taurus-Auriga star forming regions based on multi-epoch high-resolution optical spectra from the Magellan Clay 6.5 m telescope supplemented by mid-infared photometry from the Spitzer Space Telescope. In contrast to previous studies in the Orion Nebula Cluster and NGC 2264, we do not see a clear signature of disk braking in Tau-Aur and Cha I. We find that both accretors and non-accretors have similar distributions of v sin i. The rotational velocities in both regions show a clear mass dependence, with F--K stars rotating on average about twice as fast as M stars, consistent with results reported for other clusters of similar age. Similarly, we find the upper envelope of the observed values of specific angular momentum j varies as M^0.5 for our sample which spans a mass range of ~0.16 to ~3 M_sun. This power law complements previous studies in Orion which estimated j is proportional to M^0.25 for < ~2 Myr stars in the same mass regime, and a sharp decline in j with decreasing mass for older stars (~10 Myr) with M < 2 M_sun. For a subsample of 67 objects with mid-IR photometry, we examine the connection between accretion signatures and dusty disks: in the vast majority of cases (63/67), the two properties correlate well, which suggests that the timescale of gas accretion is similar to the lifetime of inner disks.

description: The paper is concerned with the adaptive finite element solution of linear elliptic differential equations using equidistributing meshes. A strategy is developed for defining this type of mesh based on residual-based a posteriori error estimates and rigorously analyzing the convergence of a linear finite element approximation using them. The existence and computation of equidistributing meshes and the continuous dependence of the finite element approximation on mesh are also studied. Numerical results are given to verify the theoretical findings.

description: We propose a physical model for generating multipartite entangled states of spin-$s$ particles that have important applications in distributed quantum information processing. Our protocol is based on a process where mobile spins induce the interaction among remote scattering centers. As such, a major advantage lies on the management of stationary and well separated spins. Among the generable states, there is a class of $N$-qubit singlets allowing for optimal quantum telecloning in a scalable and controllable way. We also show how to prepare Aharonov, W and Greenberger-Horne-Zeilinger states.

Mycotic Intracranial Aneurysm Secondary to Left Ventricular Assist Device Infection
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background

Mycotic aneurysms are a complication of infective endocarditis. Infection of left ventricular assist devices (LVADs) may lead to bacteremia and fever causing complications similar to those seen in patients with prosthetic valve endocarditis. Intracranial mycotic aneurysms are rare, and their presence is signaled by the development of subarachnoid hemorrhage in the setting of bacteremia and aneurysms located distal to the circle of Willis.

Case Presentation

We present the case of a patient with a LVAD presenting with headache who is found to have an intracranial mycotic aneurysm through computed tomography angiography of the head. The patient was successfully treated with endovascular intervention.

Conclusion

In patients with LVADs, mycotic aneurysms have been reported, however not intracranially. To the best of our knowledge, this is the first intracranial mycotic aneurysm secondary to LVAD infection that was successfully treated with endovascular repair. Intracranial mycotic aneurysms associated with LVADs are a rare phenomenon. The diagnosis of mycotic aneurysms requires a high index of suspicion in patients who present with bacteremia with or without headache and other neurological symptoms.

Dynamical Symmetry Breaking With a Fourth Generation

description: Adding a fourth generation to the Standard Model and assuming it to be valid up to some cutoff Λ, we show that electroweak symmetry is broken by radiative corrections due to the fourth generation. The effects of the fourth generation are isolated using a Lagrangian with a genuine scalar without self-interactions at the classical level. For masses of the fourth generation consistent with electroweak precision data (including the B \rightarrow K π CP asymmetries) we obtain a Higgs mass of the order of a few hundreds GeV and a cutoff Λ around 1-2 TeV. We study the reliability of the perturbative treatment used to obtain these results taking into account the running of the Yukawa couplings of the fourth quark generation with the aid of the Renormalization Group (RG) equations, finding similar allowed values for the Higgs mass but a slightly lower cut-off due to the breaking of the perturbative regime. Such low cut-off means that the effects of new physics needed to describe electroweak interactions at energy above Λ should be measurable at the LHC. We use the minimal supersymmetric extension of the standard model with four generations as an explicit example of models realizing the dynamical electroweak symmetry breaking by radiative corrections and containing new physics. Here, the cutoff is replaced by the masses of the squarks and electroweak symmetry breaking by radiative corrections requires the squark masses to be of the order of 1 TeV.

Are CP Violating Effects in the Standard Model Really Tiny?

description: We derive an effective action of the bosonic sector of the Standard Model by integrating out the fermionic degrees of freedom in the worldline approach. The CP violation due to the complex phase in the CKM matrix gives rise to CP-violating operators in the effective action. We calculate the prefactor of the appropriate next-to-leading order operators and give general estimates of CP violation in the bosonic sector of the Standard Model. In particular, we show that the effective CP violation for weak gauge fields is not suppressed by the Yukawa couplings of the light quarks and is much larger than the bound given by the Jarlskog determinant.

A study of some volcanic rocks from Harrison Mills, British Columbia
Creators: name: Burley, Brian John
Publisher: name: University of British Columbia
Year: 2012

description: Large bodies of keratophyric tuffs and keratophyric flows from Harrison Mills, British Colombia are described structurally and petrologically. The origin of the albitic feldspar in these rocks is discussed and concluded to be primary. Petrological comparisons are made between the tuffs and the flows. Both types of rocks were artificially fused to glasses, and the refractive indices of these glasses are compared. From these studies the tuffs and the lavas are concluded to be consanguineous. The keratophyric flows were analysed chemically and found similar to keratophyric rocks from other localities. The origin of the lavas is discussed. It is concluded that these rocks were probably formed by differentiation of a trondjhemitic magma possibly contaminated by soda rich sediments.

On the relation of standard and helical magnetorotational instability

description: The magnetorotational instability (MRI) plays a crucial role for cosmic structure formation by enabling turbulence in Keplerian disks which would be otherwise hydrodynamically stable. With particular focus on MRI experiments with liquid metals, which have small magnetic Prandtl numbers, it has been shown that the helical version of this instability (HMRI) has a scaling behaviour that is quite different from that of the standard MRI (SMRI). We discuss the relation of HMRI to SMRI by exploring various parameter dependencies. We identify the mechanism of transfer of instability between modes through a spectral exceptional point that explains both the transition from a stationary instability (SMRI) to an unstable travelling wave (HMRI) and the excitation of HMRI in the inductionless limit. For certain parameter regions we find new islands of the HMRI.

description: We study the problem of spatially stabilising four dimensional extremal black holes in background electric/magnetic fields. Whilst looking for stationary stable solutions describing black holes kept in external fields we find that taking a continuum limit of Denef et al's multi-center solutions provides a supergravity description of such backgrounds within which a black hole can be trapped in a given volume. This is realised by levitating a black hole over a magnetic dipole base. We comment on how such a construction resembles a mechanical Levitron.

description: An alphabet soup of government agencies like FERC, EPA, EIA, PHMSA, MSHA and the ISOs and RTOs collect and publish terabytes of data about the US energy system. It includes operating costs and fuel consumption, hourly power output and GHG emissions, and the age and length of natural gas pipelines, the price of electricity every 5 minutes at thousands of nodes in the grid, coal production numbers and much much more. In theory all this data is public and freely available, but in practice it takes a lot of wrangling to make it usable for analysis. The result: it's packaged up by one or two platform monopolies that charge tens of thousands of dollars a year for easy access, excluding most non-corporate users. But for anyone interested in the ongoing transformation of our energy system and its climate impacts, this data is a treasure trove worth excavating. Catalyst Cooperative's Public Utility Data Liberation (PUDL) Project has been working for the last 2.5 years to liberate this data and make it freely accessible to activists, data journalists, and researchers working on US climate and energy policy. This talk takes a look at what the data is, where it comes from, why it's interesting, how we're processing it and making it available, and some of the challenges we're facing and opportunities we see ahead.

Upper Devonian corals of the Canadian Cordilleran region
Creators: name: Thomlinson, Arnold Gordon
Publisher: name: University of British Columbia
Year: 2012

description: Preliminary to the descriptions of genera and species is a very brief discussion of coral terminology and classification. The thesis embodies descriptions and illustrations of 29 genera and 42 species of fossil corals, reported in the literature to occur in Upper Devonian rocks of western Canada. Although most of these are reported from the Rocky Mountain area, several species from the Mackenzie River-Mackenzie Mountains area are also included. In addition, species reported from the Upper Devonian Outcrops east of the Rocky Mountains have been dealt with. Numerous taxonomic problems encountered in the study are discussed in remarks on the genera and species involved. Fossil corals collected from the region drained by the headwaters of the North Saskatchewan River are described, identified and illustrated. Nine genera and 14 species are recognized in the collection. Of these, 1 genus and 4 species do not appear to have been previously reported to occur in the Upper Devonian beds of the Rocky Mountains in Canada. The species of Coenites described is possibly a new one but it cannot be regarded as such until a study is made of literature which, at present, is not available. From this study of Upper Devonian corals, the writer concludes that the DISPHYLLIDAE are in need of division into new subfamilies, and he suggests two characteristics whose phylogenetic significance requires investigation. However, it is considered that existing paleontologlc data Is neither comprehensive enough nor precise enough to permit such an undertaking. Reasons are given for the present inadequacies of knowledge of Upper Devonian corals and recommendations are made for improvement of the situation.

description: We investigated the role of T cell cytotoxicity inducing factor 1 (TCF1) in the induction of a cytotoxic T cell response. We found that help-deficient thymocyte cultures supplied with saturating amounts of purified IL 2 did not develop CTL in a 5-day culture. The expression of cytotoxicity was dependent on the addition of TCF1 derived from the T cell hybridoma K15. TCF1 also induced proliferation of thymocytes in the presence of IL 2. Only the PNA- thymocyte subpopulation responded to TCF1 with proliferation and cytotoxicity in the presence of IL 2. The monokine IL 1 also induced proliferation in this subpopulation but failed to induce cytotoxicity. IL 1 was further distinguished from TCF1 by inhibition of IL 1-induced but not TCF1-induced proliferation by anti-IL 1 antibodies. In addition, using anti-IL 2 receptor antibodies (AMT 13), we showed that TCF1 in the presence of IL 2 substantially increased IL 2 receptor expression in thymocytes. IL 1 had the same effect on induction of IL 2 receptor expression as TCF1. Because some effects of IL 1 and TCF1 are distinct and some overlap, we discuss whether IL 1 and TCF1 induce different subsets of PNA- thymocytes.

Further studies on the hydrothermal stability of quartz
Creators: name: Soles, James Albert
Publisher: name: University of British Columbia
Year: 2012

description: Quartz and quartzite are subjected to moderate confining pressures and compressive stresses in water and alkaline media. Planes of liquid inclusions in quartz are not affected nor is quartz recrystallized under the experimental conditions imposed. Calculations of the pressure unit's limitations are made, and modifications for its future use are suggested. A complete analysis of sodium disilicate, produced in the experiments, is presented.

On the Failure of Fixed-Point Theorems for Chain-complete Lattices in the Effective Topos

Publisher: name: arXiv
Year: 2009
Subjects: subject: Logic (math.LO)
subject: Category Theory (math.CT)
subject: FOS: Mathematics
subject: 03G30, 03G10

description: In the effective topos there exists a chain-complete distributive lattice with a monotone and progressive endomap which does not have a fixed point. Consequently, the Bourbaki-Witt theorem and Tarski's fixed-point theorem for chain-complete lattices do not have constructive (topos-valid) proofs.

Ma davvero piovono diamanti, là sui due giganti del Sistema solare? L’ipotesi, tanto suggestiva quanto controversa, è stata presentata al convegno di planetologia in corso a Denver e ripresa sulle pagine dell’ultimo numero di Nature. E si aggiunge agli studi che ipotizzavano mari di diamante su Urano o addirittura interi pianeti fatti di questo materiale.
Characterizing the Properties of Clusters of Galaxies as a Function of Luminosity and Redshift

description: We report the application of a new Monte Carlo method, Smoothed Particle Inference (SPI, described in a pair of companion papers), towards analysis and interpretation of X-ray observations of clusters of galaxies with the XMM-Newton satellite. Our sample consists of publicly available, well-exposed observations of clusters at redshifts z > 0.069, totaling 101 objects. We determine the luminosity and temperature structure of the X-ray emitting gas, with the goal to quantify the scatter and the evolution of the L_X - T relation, as well as to investigate the dependence on cluster substructure with redshift. We confirm that L_X \propto T^3 and we find a weak redshift dependence (\propto (1+z)^(β_LT), β_LT=0.50 +- 0.34), in contrast to some Chandra results. The level of dynamical activity is established using the "power ratios" method, and we find signs of evolution in the P_3/P_0 power ratio. A new method, the "temperature two-point correlation function," is proposed. This method is used to determine the "power spectrum" of temperature fluctuations in the X-ray emitting gas as a function of spatial scale. We show how this method can be fruitfully used to identify cooling core clusters as well as those with disturbed structures, presumably due to on-going or recent merger activity.
