description: Herbert Fröhlich is generally credited with having predicted the fundamental role of electron-phonon interactions in superconductivity in 1950, and in particular the isotope effect, without any experimental input. Here we examine the facts on which this belief is based and point out that whether or not the generally accepted view is true depends on the meaning of the word {\it shortly}.

description: The standard National Institute of Health (NIH) biosketch provides a snapshot of an academic’s achievements, but mine, like most, lists only the highpoints and not many of the other major factors that influenced my career in academic medicine. A review of some notable omissions may provide some useful insights. A molecular biology major in college, my several summers of bench research on cyanobacteria probably helped get me into medical school by offsetting the Cs in physics and organic chemistry (Wellesley didn’t do grade inflation). I did not appreciate that all those pathways require rote memorization, a skill I picked up later, which is now made unnecessary by Wikipedia. Nor does my biosketch include the hours I spent poring over the writings of Peter Kropotkin and Emma Goldman while struggling with my own personal involvement in the turbulent political scene of the ‘70s. That was simply listed as “honors research in political philosophy.” Once in medical school, also amidst a background of political upheaval, I sought out a summer research position in a lab, which in retrospect provided a setting in which I had some control. Bench research provided a sense of rationality and order: testable hypotheses, controls, and tangible outcomes, some of which were actually publishable. The social and political issues then, as now, seemed insurmountable. This part of my biosketch that delineates postgraduate training omits all of the distractions of ongoing political turmoil and suggests I learned molecular biology skills as well as clinical infectious diseases. It fails to mention the most notable achievement of my fellowships, namely the births of my sons.

description: Finite size scaling for the Schrödinger equation is a systematic approach to calculate the quantum critical parameters for a given Hamiltonian. This approach has been shown to give very accurate results for critical parameters by using a systematic expansion with global basis-type functions. Recently, the finite element method was shown to be a powerful numerical method for ab initio electronic structure calculations with a variable real-space resolution. In this work, we demonstrate how to obtain quantum critical parameters by combining the finite element method (FEM) with finite size scaling (FSS) using different ab initio approximations and exact formulations. The critical parameters could be atomic nuclear charges, internuclear distances, electron density, disorder, lattice structure, and external fields for stability of atomic, molecular systems and quantum phase transitions of extended systems. To illustrate the effectiveness of this approach we provide detailed calculations of applying FEM to approximate solutions for the two-electron atom with varying nuclear charge; these include Hartree-Fock, density functional theory under the local density approximation, and an "exact"' formulation using FEM. We then use the FSS approach to determine its critical nuclear charge for stability; here, the size of the system is related to the number of elements used in the calculations. Results prove to be in good agreement with previous Slater-basis set calculations and demonstrate that it is possible to combine finite size scaling with the finite-element method by using ab initio calculations to obtain quantum critical parameters. The combined approach provides a promising first-principles approach to describe quantum phase transitions for materials and extended systems.

Turbulent molecular gas and star formation in the shocked intergalactic medium of Stephan's Quintet

description: We report on single-dish radio CO observations towards the inter-galactic medium (IGM) of the Stephan's Quintet (SQ) group of galaxies. Extremely bright mid-IR H2 rotational line emission from warm molecular gas has been detected by Spitzer in the kpc-scale shock created by a galaxy collision. We detect in the IGM CO(1-0), (2-1) and (3-2) line emission with complex profiles, spanning a velocity range of 1000 km/s. The spectra exhibit the pre-shock recession velocities of the two colliding gas systems (5700 and 6700 km/s), but also intermediate velocities. This shows that much of the molecular gas has formed out of diffuse gas accelerated by the galaxy-tidal arm collision. A total H2 mass of 5x10^9 Msun is detected in the shock. The molecular gas carries a large fraction of the gas kinetic energy involved in the collision, meaning that this energy has not been thermalized yet. The turbulent kinetic energy of the H2 gas is at least a factor of 5 greater than the thermal energy of the hot plasma heated by the collision. The ratio between the warm H2 mass derived from Spitzer IRS spectroscopy and the H2 mass derived from CO fluxes is ~0.3 in the IGM of SQ, which is 10-100 times higher than in star-forming galaxies. In the shocked region, the ratio of the PAH-to-CO surface luminosities, commonly used to measure the star formation efficiency of the H2 gas, is lower (up to a factor 75) than the observed values in star-forming galaxies. We suggest that turbulence fed by the galaxy-tidal arm collision maintains a high heating rate within the H2 gas. This interpretation implies that the velocity dispersion on the scale of giant molecular clouds in SQ is one order of magnitude larger than the Galactic value. The high amplitude of turbulence may explain why this gas is not forming stars efficiently. [abridged version]

description: No abstracts are to be cited without prior reference to the author.Contaminant monitoring for priority pollutants is an integral part of the UK obligations under the Water Framework Directive (WFD) and OSPAR monitoring programmes. Also, the Marine Strategy Framework Directive (MSFD) requires Good Ecological Status (GES) be maintained. Descriptor 8 of GES states that concentrations of contaminants are at levels not giving rise to pollution effects. It is therefore important to establish whether environmental concentrations of chemicals on existing EC and OSPAR chemical priority lists are of toxicological significance, and whether there are additional substances with potential to cause harm in the UK marine environment. In order to inform this process, passive samplers were deployed to provide information on the presence and freely dissolved concentrations of a wide range of potential target substances for monitoring programmes. The survey covered a wide range of locations around the UK, from industrial estuaries to relatively unaffected offshore waters. Samplers were deployed for periods of 4—8 weeks during spring and summer 2009. In a smaller subsequent follow-up survey in early 2010, samplers were also deployed alongside mussels. The mussels were analysed for priority substances as well as for effects such as stress on stress, DNA damage, neutral red, and a number of biomarkers via qPCR. This presentation includes an overview of the project undertaken, the advantages and disadvantages associated with undertaking such a survey using these methods, the establishment of sampling rates for compounds previously unstudied using these methods, and the move towards establishing ”safe” concentrations using these methods.

Nearly Doubling the Throughput of Multiuser MIMO Systems Using Codebook Tailored Limited Feedback Protocol

Year: 2011

description: We present and analyze a new robust feedback and transmit strategy for multiuser MIMO downlink communication systems, termed Rate Approximation (RA). RA combines the flexibility and robustness needed for reliable communications with the user terminal under a limited feedback constraint. It responds to two important observations. First, it is not so significant to approximate the channel but rather the rate, such that the optimal scheduling decision can be mimicked at the base station. Second, a fixed transmit codebook at the transmitter is often better when therefore the channel state information is more accurate. In the RA scheme the transmit and feedback codebook are separated and user rates are delivered to the base station subject to a controlled uniform error. The scheme is analyzed and proved to have better performance below a certain interference plus noise margin and better behavior than the classical Jindal formula. LTE system simulations sustain the analytic results showing performance gains of up to 50% or 70% compared to zeroforcing when using multiple antennas at the base station and multiple antennas or a single antenna at the terminals, respectively. A new feedback protocol is developed which inherently considers the transmit codebook and which is able to deal with the complexity issue at the terminal.

description: No abstracts are to be cited without prior reference to the author.This study presents a preconcentration/separation procedure for the solid-phase extraction of heavy metals in pulp wastewaters, seawater, and complex liquid matrices. The preconcentration procedure was optimized by using model solutions containing heavy metals of interest. The effect of the matrix constituents was also investigated. Equilibrium studies helped to shed light on the bonding and adsorption characteristics. The metal recovery after spiking the pulp filtrate with Cu, Ni, and Pb to constitute a concentration of 0.1 and 0.2 ppm was 120%, 91%, and 93%, respectively. The dynamic flow adsorption system did not fit the Langmuir isotherm, which assumes a homogeneous system with no interaction between adsorbed molecules, even on adjacent sites. Langmuir isotherm correlation coefficients (R2) for the linear plots were 0.277, 0.389, and 0.272 for Cu, Mn, and Fe, respectively. The system, however, demonstrated a good fit when using the Freundlich adsorption isotherm model, with correlation coefficients (R2) of 0.612, 0.810, and 0.750 for Cu, Mn, and Fe, respectively

description: We put forward a dissipative preparation scheme for strongly correlated photon states. Our approach is based on a two-photon loss mechanism that is realised via a single four-level atom inside a bimodal optical cavity. Each elementary two-photon emission event removes one photon out of each of the two modes. The dark states of this loss mechanism are given by NOON states and arbitrary superpositions thereof. We find that the steady state of the two cavity modes exhibits entanglement and for certain parameters, a mixture of two coherent entangled states is produced. We discuss how the quantum correlations in the cavity modes and the output fields can be measured.

description: No abstracts are to be cited without prior reference to the author.A previous study performed in four areas along the Iberian Mediterranean coast suggested lower DNA liver integrity in red mullet (Mullus barbatus) caught from Cartagena (southeast Spain) in comparison with the other areas (Delta Ebro, Valencia, and Guardamar), though significant differences were not demonstrated. Here we present the results of a study on other types of genotoxic measurements in red mullet. These include erythrocyte micronuclei (MN) frequency and other nuclei abnormalities in peripheral blood samples (n > 5000 blood cells/fish) of red mullet (n = [19–34]) caught in seven different areas of the Iberian coast (Barcelona, Tarragona, Delta Ebro, Valencia, Cartagena, Almería, and Málaga). Mean MN frequency (expressed per 1000 cells/individual fish) was significantly higher (1.26; p < 0.001) in fish caught from Barcelona than in those from the other areas (0.23–0.59). However, other kinds of abnormalities such as binucleated and lobed nuclei were more frequently observed in fish from Cartagena and Almería. On the basis of our findings, and the fact that the use of this type of biomarker is relatively cheap and blood can be sampled easily on site, this biomarker will be routinely incorporated in the Spanish biomonitoring programme of marine contamination on the Mediterranean coast.

description: The most general basis of operators parametrizing a low-scale departure from the SM particle content is constructed. The SM gauge invariance is enforced, and operators of lowest dimensions are retained separately for a new light neutral particle of spin 0, 1/2, 1, and 3/2. The basis is further decomposed into couplings to the SM Higgs/gauge fields, to pairs of quark/lepton fields, and to baryon/lepton number violating combinations of fermion fields. This basis is then used to systematically investigate the discovery potential of the rare FCNC decays of the K and B mesons with missing energy in the final state. The most sensitive decay modes in the s to d, b to d, and b to s sectors are identified and compared for each type of couplings to the new invisible state.

Post-silicon code coverage for functional verification of systems-on-chip
Creators: name: Karimibiuki, Mehdi
Publisher: name: University of British Columbia
Year: 2012

description: Post-silicon validation requires effective techniques to better evaluate the functional correctness of modern systems-on-chip. Coverage is the standard measure for validation effectiveness and is extensively used pre-silicon. However, there is little data evaluating the coverage of post-silicon validation efforts on industrial-scale designs. This thesis addresses this knowledge-gap. We employ code coverage, which is one of the most frequently used coverage technique in simulation, and apply it post-silicon. To show our coverage methodology in practice, we employ an industrial-size open source SoC that is based on the SPARC architecture and is synthesizable to FPGA. We instrument code coverage in a number of IP cores and boot Linux as our experiment to evaluate coverage --- booting an OS is a typical industrial post-silicon test. We also compare coverages between pre-silicon directed tests and the post-silicon Linux boot. Our results show that in some blocks, the pre-silicon and post-silicon tests can achieve markedly different coverage figures --- in one block we measured over 50 percentage point coverage difference between the pre- and post-silicon results, which signifies the importance of post-silicon coverage. Moreover, we calculate the area overhead imposed by the additional coverage circuitry on-chip. We apply state-of-the-art software analysis techniques to reduce the excessively large overhead yet preserve data accuracy. The results in this thesis are valuable data for guidance to future research in post-silicon coverage.

description: In this paper we study asymptotically hyperbolic manifolds given as graphs of asymptotically constant functions over hyperbolic space $\bH^n$. The graphs are considered as subsets of $\bH^{n+1}$ and carry the induced metric. For such manifolds the scalar curvature appears in the divergence of a 1-form involving the integrand for the asymptotically hyperbolic mass. Integrating this divergence we estimate the mass by an integral over an inner boundary. In case the inner boundary satisfies a convexity condition this can in turn be estimated in terms of the area of the inner boundary. The resulting estimates are similar to the conjectured Penrose inequality for asymptotically hyperbolic manifolds. The work presented here is inspired by Lam's article concerning the asymptotically Euclidean case.

description: No abstracts are to be cited without prior reference to the author.The present study was undertaken to determine the biochemical compositions (carbohydrate, protein, and lipid) of the marine organisms Villorita cyprinoides var. cochinensis in the Cochin Estuary, which is situated on the southwest coast of India. This organism provides highly nutritious food for human consumption as they store large quantities of glycogen and fat. These biochemical compositions are fundamental biomolecules in all aspects of cell structure and function and are also a major source of energy in the human diet. Our understanding of the biochemical composition of marine organisms plays an important role in utilizing their nutritive value. The samples were collected seasonally. The tissues were analysed and the results show that the lipid, carbohydrate, and protein levels were high during the pre-monsoon season and gradually dropped during the monsoon and post-monsoon seasons. The ratio of carbohydrate was lower that that of other nutrients, such as proteins and lipids in animal tissues, especially in aquatic animals.

description: In this work, we present a realistic analysis of the potential of the present-day reactor experiments Double Chooz, Daya Bay and RENO for probing the existence of sterile neutrinos. We present exclusion regions for sterile oscillation parameters for each of these experiments, using simulations with realistic estimates of systematic errors and detector resolutions, and compare the sterile parameter sensitivity regions we obtain with the existing bounds from other reactor experiments. We find that these experimental set-ups give significant bounds on the parameter Θ_{ee} especially in the low sterile oscillation region 0.01 < Δm_{41}^2 < 0.05 eV^2. These bounds can add to our understanding of the sterile neutrino sector since there is still a tension in the allowed regions from different experiments for sterile parameters.

description: No abstracts are to be cited without prior reference to the author.Because organic pollutants are stable and are found throughout the natural environment, their effects on animal physiology or their dynamics within trophic networks have been studied for many years. However, behavioural studies are rarely used in ecotoxicology although these have the potential to reveal compensation mechanisms and therefore provide a link between individual behaviours and population characteristics. The aim of our study was to identify relevant behavioural indicators affected by PCB contaminants in two fish species, the common sole (Solea solea) and the zebrafish (Danio rerio). Juvenile fish were exposed through diet to two environmental concentrations of PCBs and different behavioural traits were compared with those of control fish. For each species, we studied: (i) exploratory behaviour in a T-maze, (ii) 24-h swimming activity, (iii) background colour preference and (iv) group dispersion. Because of ecological differences between the two species, we also examined: (v) cryptic and burying capacities in sole and (vi) larvae locomotory activity of zebrafish. State-of-the-art full-automatic behavioural analyses using Ethovision video tracking solution (Noldus, The Netherlands) to analyse swimming activity measures (e.g. velocity, mobility, distance travelled) was combined with semi-automatic analysis (e.g. interindividual distances, spatial distribution, behaviour quantification) to obtain a wider range of potential behavioural variables. Infrared lighting with dedicated sensitive cameras was also used to study fish and larvae both in the light and in the dark. The differential responses and the relevance of the variable responses observed are discussed in the context of the ecological requirements of fish.

 Siphona Meigen, 1803: 281. Type species: Musca geniculata De Geer, 1776, by designation of the ICZN (1974: 157, Opinion 1008).
See O’HARA (1989) for a complete list of synonyms.
 Remarks. Species of the genus Siphona are distinguished from other genera of the Siphonini by the following combination of characters: CuA+CuP reaching wing margin; lower katepisternal seta strong and subequal in length to anterior one; lower proepimeral seta hair-like and directed upward or absent. O’HARA (1988) examined the first instar larva of the Siphonini and found the same features in the genus Siphona: 2–10 large spinules and a dominant row of spinules on the posteroventral margin of the abdominal segments 6 and 7, respectively.

description: C-X-C motif chemokine 5 is primarily chemotactic for neutrophils and previously shown to increase in the bronchoalveolar lavage fluid of patients with chronic obstructive pulmonary disease. However, whether C-X-C motif chemokine 5 levels correlate with lung function decline in patients or mouse model of chronic obstructive pulmonary disease was not clear. The mouse model was induced by cigarette smoke exposure. Plasma/serum and bronchoalveolar lavage fluid were obtained from patients and mouse model of chronic obstructive pulmonary disease; C-X-C motif chemokine 5 levels were assessed and correlated with lung functions and granulocyte-colony stimulating factor levels, respectively. The C-X-C motif chemokine 5 levels increased and correlated to granulocyte-colony stimulating factor levels in both plasma/serum and bronchoalveolar lavage fluid obtained from patients and mouse model of chronic obstructive pulmonary disease. Circulating levels of C-X-C motif chemokine 5 correlated to lung functions decline in patients and mouse model. Granulocyte-colony stimulating factor might coordinate with C-X-C motif chemokine 5 in the pathogenesis of neutrophilic inflammation in chronic obstructive pulmonary disease. Circulating C-X-C motif chemokine 5 might serve as a potential blood-based biomarker to add additional modest predictive value on the preliminary screening and diagnosis of chronic obstructive pulmonary disease.Key messagesCirculating C-X-C motif chemokine 5 might serve as a potential blood-based biomarker to add additional modest predictive value on the preliminary screening and diagnosis of COPD.Granulocyte-colony stimulating factor might coordinate with C-X-C motif chemokine 5 in the pathogenesis of neutrophilic inflammation in chronic obstructive pulmonary disease.

description: No abstracts are to be cited without prior reference to the author.The assessment of chemical contaminants and biological effects in aquatic environments is everyday work for most countries within the ICES community. In most cases concentrations and enzyme activities are transformed into biological effects: into individuals, congeners, communities, or ecosystems. Behavioural experiments can help us to see the effect of pollutant in “real” nature, without extrapolating numbers into effects. Nevertheless, behavioural experiments are difficult to manage and results may not be as unequivocal as scientists would wish. This presentation gives an overview of behavioural experiments with crucian carp (Carassius carassius), and the effect of high pH on fish. How do fish perceive information about pH, and are they able to avoid harmful environments? How does fish feeding behaviour alter when affected by high pH? On what level can we compare EOG (electroolfactogram) results with behavioural experiments? These are the questions that will be answered.

description: Considering the matter power spectrum covariance matrix, it has recently been found that there is a potentially dominant effect on mildly non-linear scales due to power in modes of size equal to and larger than the survey volume. This {\it beat coupling} effect has been derived analytically in perturbation theory and while it has been tested with simulations, some questions remain unanswered. Moreover, there is an additional effect of these large modes, which has so far not been included in analytic studies, namely the effect on the estimated {\it average} density which enters the power spectrum estimate. In this article, we work out analytic, perturbation theory based expressions including both the beat coupling and this {\it local average effect} and we show that while, when isolated, beat coupling indeed causes large excess covariance in agreement with the literature, in a realistic scenario this is compensated almost entirely by the local average effect, leaving only $\sim 10 %$ of the excess. We test our analytic expressions by comparison to a suite of large N-body simulations. For the variances, we find excellent agreement with the analytic expressions for $k < 0.2 h$Mpc$^{-1}$ at $z=0.5$, while the correlation coefficients agree to beyond $k=0.4 h$Mpc$^{-1}$. As expected, the range of agreement increases towards higher redshift and decreases slightly towards $z=0$. We finish by including the large-mode effects in a full covariance matrix description for arbitrary survey geometry and confirming its validity using simulations. This may be useful as a stepping stone towards building an actual galaxy (or other tracer's) power spectrum covariance matrix. [abridged]

Nonparametric Bayesian models for Markov jump processes

Publisher: name: University of British Columbia

description: Markov jump processes (MJPs) have been used as models in various fields such as disease progression, phylogenetic trees, and communication networks. The main motivation behind this thesis is the application of MJPs to data modeled as having complex latent structure. In this thesis we propose a nonparametric prior, the gamma-exponential process (GEP), over MJPs. Nonparametric Bayesian models have recently attracted much attention in the statistics community, due to their flexibility, adaptability, and usefulness in analyzing complex real world datasets. The GEP is a prior over infinite rate matrices which characterize an MJP; this prior can be used in Bayesian models where an MJP is imposed on the data but the number of states of the MJP is unknown in advance. We show that the GEP model we propose has some attractive properties such as conjugacy and simple closed-form predictive distributions. We also introduce the hierarchical version of the GEP model; sharing statistical strength can be considered as the main motivation behind the hierarchical model. We show that our hierarchical model admits efficient inference algorithms. We introduce two inference algorithms: 1) a “basic” particle Markov chain Monte Carlo (PMCMC) algorithm which is an MCMC algorithm with sequences proposed by a sequential Monte Carlo (SMC) algorithm; 2) a modified version of this PMCPC algorithm with an “improved” SMC proposal. Finally, we demonstrate the algorithms on the problems of estimating disease progression in multiple sclerosis and RNA evolutionary modeling. In both domains, we found that our model outperformed the standard rate matrix estimation approach.

description: We have investigated the thermal conductivity κ_mag of high-purity single crystals of the spin chain compound Sr2CuO3 which is considered an excellent realization of the one-dimensional spin-1/2 antiferromagnetic Heisenberg model. We find that the spinon heat conductivity κ_mag is strongly enhanced as compared to previous results obtained on samples with lower chemical purity. The analysis of κ_mag allows to compute the spinon mean free path l_mag as a function of temperature. At low-temperature we find l_mag\sim0.5\mum, corresponding to more than 1200 chain unit cells. Upon increasing the temperature, the mean free path decreases strongly and approaches an exponential decay ~1/T*exp(T*/T) which is characteristic for umklapp processes with the energy scale k_B T*. Based on Matthiesen's rule we decompose l_mag into a temperature-independent spinon-defect scattering length l0 and a temperature dependent spinon-phonon scattering length l_sp(T). By comparing l_mag(T) of Sr2CuO3 with that of SrCuO2, we show that the spin-phonon interaction, as expressed by l_sp is practically the same in both systems. The comparison of the empirically derived l_sp with model calculations for the spin-phonon interaction of the one-dimensional spin-1/2 XY model yields reasonable agreement with the experimental data.

description: We investigate the ground-state phase diagram of an anisotropic Heisenberg model on the honeycomb lattice with competing interactions. We use quantum Monte Carlo simulations, as well as linear spin-wave and Ising series expansions, to determine the phase boundaries of the ordered magnetic phases. We find a region without any classical order in the vicinity of a highly frustrated point. Higher-order correlation functions in this region give no signal for long-range valence-bond order. The low-energy spectrum is derived via exact diagonalization to check for topological order on small-size periodic lattices.
