description: Intrinsic Josephson-junction stacks realized in high-temperature superconductors provide a very attractive base for developing coherent sources of electromagnetic radiation in the terahertz frequency range. A promising way to synchronize phase oscillations in all the junctions is to excite an internal cavity resonance. We demonstrate that this resonance promotes the formation of an alternating coherent state, in which the system spontaneously splits into two subsystems with different phase-oscillation patterns. There is a static phase shift between the oscillations in the two subsystems which changes from 0 to $2π$ in a narrow region near the stack center. The oscillating electric and magnetic fields are almost homogeneous in all the junctions. The formation of this state promotes efficient pumping of the energy into the cavity resonance leading to strong resonance features in the current-voltage dependence.

description: We propose a method for finding gaps in the spectrum of a differential operator. When applied to the one-dimensional Hamiltonian of the quartic oscillator, a simple algebraic algorithm is proposed that, step by step, separates with a remarkable precision all the energies even for a double-well configuration in a tunnelling regime. Our strategy may be refined and generalised to a large class of 1d-problems.

description: We present how a worm hole bridge from a prior to the present universe allows us to use symmetry arguments which allow us to generate relic gravity waves, and also non massless gravitons.

description: Because the magneto-rotational instability is capable of exponentially amplifying weak preexisting magnetic fields, it might be hoped that the character of the magnetic field in accretion disks is independent of the nature of the seed field. However, the divergence-free nature of magnetic fields in highly conducting fluids ensures that their large-scale topology is preserved, no matter how greatly the field intensity is changed. By performing global two-dimensional and three-dimensional general relativistic magnetohydrodynamic disk simulations with several different topologies for the initial magnetic field, we explore the degree to which the character of the flows around black holes depends on the initial topology. We find that while the qualitative properties of the accretion flow are nearly independent of field topology, jet-launching is very sensitive to it: a sense of vertical field consistent for at least an inner disk inflow time is essential to the support of strong jets.

description: The entanglement entropy corresponding to a smooth region in general three-dimensional CFTs contains a constant universal term, $-F \subset S_{\text{EE}}$. For a disk region, $F|_{\rm disk}\equiv F_0$ coincides with the free energy on $\mathbb{S}^3$ and provides an RG-monotone for general theories. As opposed to the analogous quantity in four dimensions, the value of $F$ generally depends in a complicated (and non-local) way on the geometry of the region and the theory under consideration. For small geometric deformations of the disk in general CFTs as well as for arbitrary regions in holographic theories, it has been argued that $F$ is precisely minimized by disks. Here, we argue that $F$ is globally minimized by disks with respect to arbitrary regions and for general theories. The proof makes use of the strong subadditivity of entanglement entropy and the geometric fact that one can always place an osculating circle within a given smooth entangling region. For topologically non-trivial entangling regions with $n_B$ boundaries, the general bound can be improved to $F \geq n_B F_0$. In addition, we provide accurate approximations to $F$ valid for general CFTs in the case of elliptic regions for arbitrary values of the eccentricity which we check against lattice calculations for free fields. We also evaluate $F$ numerically for more general shapes in the so-called "Extensive Mutual Information model", verifying the general bound.

description: Leadership plays a key role in social animals, including humans, decision-making and coalescence in coordinated activities such as hunting, migration, sport, diplomatic negotiation etc. In these coordinated activities, leadership is a process that organizes interactions among members to make a group achieve collective goals. Understanding initiation of coordinated activities allows scientists to gain more insight into social species behaviors. However, by using only time series of activities data, inferring leadership as manifested by the initiation of coordinated activities faces many challenging issues. First, coordinated activities are dynamic and are changing over time. Second, several different coordinated activities might occur simultaneously among subgroups. Third, there is no fundamental concept to describe these activities computationally. In this paper, we formalize Faction Initiator Inference Problem and propose a leadership inference framework as a solution of this problem. The framework makes no assumption about the characteristics of a leader or the parameters of the coordination process. The framework performs better than our non-trivial baseline in both simulated and biological datasets (schools of fish). Moreover, we demonstrate the application of our framework as a tool to study group merging and splitting dynamics on another biological dataset of trajectories of wild baboons. In addition, our problem formalization and framework enable opportunities for scientists to analyze coordinated activities and generate scientific hypotheses about collective behaviors that can be tested statistically and in the field.

description: Near-field radio holography is a common method for measuring and aligning mirror surfaces for millimeter and sub-millimeter telescopes. In instruments with more than a single mirror, degeneracies arise in the holography measurement, requiring multiple measurements and new fitting methods. We present HoloSim-ML, a Python code for beam simulation and analysis of radio holography data from complex optical systems. This code uses machine learning to efficiently determine the position of hundreds of mirror adjusters on multiple mirrors with few micron accuracy. We apply this approach to the example of the Simons Observatory 6m telescope.

description: Best-fit values of recent global analyzes of neutrino data imply large solar neutrino mixing, vanishing U_{e3} and a non-maximal atmospheric neutrino mixing angle theta_{23}. We show that these values emerge naturally by the hypothesis of "scaling" in the Majorana neutrino mass matrix, which states that the ratios of its elements are equal. It also predicts an inverted hierarchy for the neutrino masses. We point out several advantages and distinguishing tests of the scaling hypothesis compared to the L_e - L_mu - L_tau flavor symmetry, which is usually assumed to provide an understanding of the inverted hierarchy. Scenarios which have initially vanishing U_{e3} and maximal atmospheric neutrino mixing are shown to be unlikely to lead to non-maximal theta_{23} while keeping simultaneously U_{e3} zero. We find a peculiar ratio of the branching ratios mu -> e gamma and tau -> e gamma in supersymmetric seesaw frameworks, which only depends on atmospheric neutrino mixing and results in tau -> e gamma being unobservable. The consequences of the scaling hypothesis for high energy astrophysical neutrinos at neutrino telescopes are also investigated. Then we analyze a seesaw model based on the discrete symmetry D_4 times Z_2 leading to scaling in the low energy mass matrix and being capable of generating the baryon asymmetry of the Universe via leptogenesis. The relevant CP phase is identical to the low energy Majorana phase and successful leptogenesis requires an effective mass for neutrinoless double beta decay larger than 0.045 eV.

description: We report theoretical and experimental work on the development of a vortex qubit based on a microshort in an annular Josephson junction. The microshort creates a potential barrier for the vortex, which produces a double-well potential under the application of an in-plane magnetic field; The field strength tunes the barrier height. A one-dimensional model for this system is presented, from which we calculate the vortex depinning current and attempt frequency as well as the interwell coupling. Implementation of an effective microshort is achieved via a section of insulating barrier that is locally wider in the junction plane. Using a junction with this geometry we demonstrate classical state preparation and readout. The vortex is prepared in a given potential well by sending a series of "shaker" bias current pulses through the junction. Readout is accomplished by measuring the vortex depinning current.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study the factorised steady state of a general class of mass transport models in which mass, a conserved quantity, is transferred stochastically between sites. Condensation in such models is exhibited when above a critical mass density the marginal distribution for the mass at a single site develops a bump, $p_{\rm cond}(m)$, at large mass $m$. This bump corresponds to a condensate site carrying a finite fraction of the mass in the system. Here, we study the condensation transition from a different aspect, that of extreme value statistics. We consider the cumulative distribution of the largest mass in the system and compute its asymptotic behaviour. We show 3 distinct behaviours: at subcritical densities the distribution is Gumbel; at the critical density the distribution is Fréchet, and above the critical density a different distribution emerges. We relate $p_{\rm cond}(m)$ to the probability density of the largest mass in the system.

A study of secondary structure predictive methods for proteins and the relationship between physical-chemical properties and enzymatic activity of some aspartyl proteinases
Creators: name: Yada, Rickey Yoshio
Publisher: name: University of British Columbia
Year: 2010

description: In the first of two studies, four algorithms were assessed for their ability to accurately determine protein secondary structure from circular dichroism spectral data in relation to X-ray data. The majority of the algorithms examined showed highly significant (P<0.001) correlation coefficients for ∝-helix and β-sheet determination while the correlation coefficients using the simplex optimization algorithm with n = variable (in the presence of concanavalin A) were significant at P<0.05. None of the algorithms examined showed significant (P>0.05) correlation coefficients for β-turn determination. Significant (P<0.05) correlation coefficients were obtained for random coil determination from both the simplex optimization algorithm (in the absence of concanavalin A) and the algorithm of Chang et al. (1978). The simplex optimization algorithm with n = 10.4 compared favourably to the method of Chang et al. (1978) in the absence of concanavalin A, and may serve as an alternative algorithm to solve least squares. The algorithm of Provencher and Glockner (1981) demonstrated the greatest versatility for secondary structure determination of the four algorithms examined. In the second study, the relationship between physical-chemical properties and the enzymatic activity of aspartyl proteinases was investigated. Using the diagonal plot method, pepsin and chymosin showed the highest degree of primary sequence homology while active site regions were highly homologous between the aspartyl proteinases examined. Secondary structure prediction methods indicated that chymosin, pepsin, peni-cillopepsin and Mucor miehei proteinase had relatively high proportions of β-sheet, with active site aspartic acid residues located in β-turn regions. Near-UV and far-UV CD spectral analysis indicated that changes in spectra occurred in the neutral to alkaline pH range. Secondary structure determination from far-UV CD spectral data demonstrated that the β-sheet fraction of the aspartyl proteinases decreased above pH 6.3. The milk-clotting to proteolytic activity ratio of the aspartyl proteinases decreased with increasing pH. Principal components derived from various structural and intrinsic parameters allowed for the classification of aspartyl and non-aspartyl proteinases. Regression of the milk-clotting to the proteolytic activity ratio on the principal components indicated that a high ratio may be partially dependent on relatively high hydrophobicity, β-sheet and low charge.

description: Pentadiamond is a recently proposed new carbon allotrope consisting of a network of pentagonal rings where both sp$^2$ and sp$^3$ hybridization are present. In this work we investigated the mechanical and electronic properties, as well as, the thermal stability of pentadiamond using DFT and fully atomistic reactive molecular dynamics (MD) simulations. We also investigated its properties beyond the elastic regime for three different deformation modes: compression, tensile and shear. The behavior of pentadiamond under compressive deformation showed strong fluctuations in the atomic positions which are responsible for the strain softening at strains beyond the linear regime, which characterizes the plastic flow. As we increase temperature, as expected, Young's modulus values decrease, but this variation (up to 300 K) is smaller than 10\% (from 347.5 to 313.6 GPa), but the fracture strain is very sensitive, varying from $\sim$44\% at 1K to $\sim$5\% at 300K.

description: In view of the recent diffractive dijet data from CDF run II, we critically re-evaluate the standard approach to the calculation of central production of dijets in quasi-elastic hadronic collisions. We find that the process is dominated by the non-perturbative region, and that even perturbative ingredients, such as the Sudakov form factor, are not under theoretical control. Comparison with data allows us to fix some of the uncertainties. Although we focus on dijets, our arguments apply to other high-mass central systems, such as the Higgs boson.
description: 37 pages, 18 figures. Two new appendices, and a discussion of the upper scale of the Sudakov form factor are introduced. The text about the calculation of the uncertainties has been rewritten

description: Recent Wilkinson Microwave Anisotropy Probe (WMAP) data confirm the Cosmic Microwave Background (CMB) quadrupole anomaly. We further elaborate our previous proposal that the quadrupole power can be naturally suppressed in axis-symmetric universes. In particular, we discuss in greater detail the CMB quadrupole anisotropy and considerably improve our analysis. As a result, we obtain tighter constraints on the direction of the axis of symmetry as well as on the eccentricity at decoupling. We find that the quadrupole amplitude can be brought in accordance with observations with an eccentricity at decoupling of about 0.35 10^{-2}. Moreover, our determination of the direction of the symmetry axis is in reasonable agreement with recent statistical analyses of cleaned CMB temperature fluctuation maps obtained by means of improved internal linear combination methods as Galactic foreground subtraction technique.

Five-dimensional regular black holes in a brane world

description: Following a recent approach, complete and analytic solutions (brane and bulk) of regular black holes are shown in a brane context. The metrics are regular both on the four-dimensional brane and in the five-dimensional bulk. Like many brane world scenarios, the bulk spacetime is asymptotically anti-de Sitter. On the other hand, a de Sitter core on the brane avoids the singularity inside the event horizon, providing then well-known regular black holes on the brane. From the bulk perspective, the regular black holes are five-dimensional objects, with the event horizon extending to the extra dimension, but the de Sitter core is entirely on the four-dimensional brane.

Airway response to inhaled air pollutants--cigarette smoke & industrial dust & fume
Creators: name: Kennedy, Susan Marguerite
Publisher: name: University of British Columbia

description: Previous studies which identified inflammation in the peripheral airways of the lung as a potentially reversible early component in the development of chronic airflow obstruction led to the investigations reported here concerning the possible early diagnosis of airway inflammation using gallium-67; the relationship between airway inflammation, increased permeability and hyper-reactivity; and peripheral airway changes seen in persons exposed to mineral dust and fume contrasted with those seen in cigarette smokers. Aerosolized radiogallium was administered in two studies, first to guinea pigs exposed to cigarette smoke and then to human smokers and the retention and clearance compared to that in non-smoking controls, and in the guinea pigs, to the degree of polymorphonuclear infiltration of the airways. The results revealed no difference in clearance between smokers and non-smokers and prolonged retention of the tracer in the lungs. Autoradiography in guinea pigs and humans suggested that the gallium was taken up by macrophages, not by polymorphonuclear cells. This suggests that the use of radiogallium to mark polymorphonuclear infiltration is not useful. Increased respiratory epithelial permeability in human smokers was demonstrated by following the disappearance from the lungs of 99m technetium labelled diethylenetriame penta acetate. However, no relationship was seen between increased permeability and airway reactivity as measured by the degree of airflow obstruction following inhalation of increasing doses of histamine. This suggests that although airway inflammation may result in increased airway permeability, this does not directly induce hyper-reactivity. Finally, peripheral airway structural and functional changes were compared in two groups of patients undergoing lung resection: one with occupational mineral dust or fume exposure and the other, not exposed to dust or fume, individually matched to the first group for age and smoking history. The results indicated increased airflow obstruction in the exposed group and excess fibrous connective tissue deposition and goblet cell metaplasia in their peripheral airways, particularly in those patients exposed to mineral dust and fume in a non-mining occupation. No increase was seen in degree of inflammatory cell infiltration of the airway walls. These results suggest that the peripheral airway response to mineral dust or fume differs qualitatively from the response to cigarette smoke.
