description: We investigate the phase space structure of the relativistic Sitnikov problem in the first post-Newtonian approximation. The phase space portraits show a strong dependence on the gravitational radius which describes the strength of the relativistic pericentre advance. Bifurcations appearing at increasing the gravitational radius are presented. Transient chaotic behavior related to escapes from the primaries are also studied. Finally, the numerically determined chaotic saddle is investigated in the context of hyperbolic and non-hyperbolic dynamics as a function of the gravitational radius.

description: Here we report on a "new" type of ordering which allows to modify the electronic structure of a graphene monolayer (ML). We have intercalated small gold clusters between the top monolayer graphene and the buffer layer of epitaxial graphene. We show that these clusters perturb the quasiparticles on the ML graphene, and act as quantum dots creating a superlattice of resonators on the graphene ML, as revealed by a strong pattern of standing waves. A detailed analysis of the standing wave patterns using Fourier Transform Scanning Tunneling Spectroscopy strongly indicates that this phenomenon can arise from a strong modification of the band structure of graphene and (or) from Charge Density Waves (CDW)where a large extension of Van Hove singularities are involved.

Seismic prediction ahead of tunnel construction using tunnel surface-waves

Publisher: name: Karlsruhe
Year: 2009

description: To increase safety and efficiency of tunnel constructions, online seismic exploration ahead of a tunnel can become a valuable tool. We developed a new forward looking seismic imaging technique to e.g. determine weak and water bearing zones ahead of the constructions. Our approach is based on the excitation and registration of tunnel surface-waves (TS-waves). These waves are excited at the tunnel face behind the cutter head of a tunnel boring machine and travel into drilling direction. Arriving at the front face they generate body-waves (mainly S-waves = ”RS”-waves) propagating further ahead. Reflected S-waves are back-converted into tunnel surface-waves (”RSSR”-waves) and can be recorded by geophones mounted on the tunnel wall. Using 3D Finite Difference modeling, an analytical solution of the wave equation in cylindrical coordinates and field data acquired at the Gotthard massive (Switzerland) we investigated the propagation characteristics of tunnel surface waves in terms of dispersion and polarization. Understanding the excitation and propagation of TS-waves is the key for developing processing and imaging techniques for our seismic look ahead prediction in tunnel constructions.

description: Temporal analysis of X-ray binaries and Active Galactic Nuclei have shown that hard X-rays react to variation of soft ones after a time delay. The opposite trend, or soft lag, has only been seen in a few rare Quasi-periodic Oscillations in X-ray binaries and recently for the AGN, 1H 0707-495, on short timescales of ~ 10^3 secs. Here, we report analysis of a XMM-Newton observation of Mrk~1040, which reveals that on the dominant variability timescale of ~ 10^4 secs, the source seems to exhibit soft lags. If the lags are frequency independent, they could be due to reverberation effects of a relativistically blurred reflection component responding to a varying continuum. Alternatively, they could be due to Comptonization delays in the case when high energy photons impinge back on the soft photon source. Both models can be verified and their parameters tightly constrained, because they will need to predict the photon spectrum, the r.m.s variability and time lag as a function of energy. A successful application of either model will provide unprecedented information on the radiative process, geometry and more importantly the size of the system, which in turn may provide stringent test of strong general relativistic effects.

A low overhead and consistent flash translation layer for embedded devices utilizing serial NOR flash
Creators: name: Fazackerley, Scott Ronald
Publisher: name: University of British Columbia
Year: 2016

description: In today's world, embedded devices are playing an ever increasing and important role in daily life. Recent interest has focused on how data from embedded devices can be harnessed. Whether it is complex environmental parameters or the average temperature in our homes, devices store and process data. Due to the vast amount of data that is generated by devices, the ability to process data on device is beneficial as it reduces the amount of data that must be transferred off the device. Flash memory is the most commonly found storage medium on embedded devices but presents challenges for developers. Flash memory is managed through the use of a flash translation layer (FTL) to address the physical limitations of memory. No FTL is currently available for the smallest of devices due to resource limitations. This thesis examines the features that are currently used in FTLs and highlights their shortcomings for use with resource constrained devices. In response to these challenges, this work introduces an FTL architecture with a minimal RAM footprint that is robust and fault-tolerant for resource constrained embedded systems. Utilizing attributes of the Adesto serial NOR Dataflash memory, a unique flash translation layer for use with serial NOR flash has been developed. Key features focus on minimizing data transfer between host and flash while maintaining persistent address translation. In addition to a low overhead and robust flash translation layer, the FTL contains a deterministic garbage collection and wear levelling strategy. This work introduces the technique of masked overwriting for NOR flash, which demonstrates the use page overwriting for modification of specific data in place. This technique offers savings in terms of write times, page erases and complexity in managing data pages, resulting in a novel FTL strategy suitable for resource constrained devices.
Mechanistic investigations of rhodium-catalyzed alkyne hydrothiolation
Creators: name: Wathier, Matthew James
Publisher: name: University of British Columbia
Year: 2016

description: Herein, thorough mechanistic investigations into alkyne hydrothiolation catalyzed by [Tp*RhI(PPh₃)₂] (Tp* = tris(3,5-dimethylpyrazolyl)borate) are reported. The mechanism is shown to proceed through an intermediate [Tp*RhIIIH(SR)] complex (R = alkyl, aryl). Alkyne migratory insertion is shown to occur chemoselectively into the Rh-SR bond, despite the availability of a Rh-H bond, to produce a rhodathiacyclobutene intermediate. The regioselectivity of product formation is revealed to be the result of a competition between 1,2 and 2,1 migratory insertion of the alkyne to produce regioisomeric rhodathiacyclobutene intermediates. Product formation occurs upon reductive elimination, which is associatively induced by coordination of thiol. Putative off-cycle intermediates [Tp*RhH(SR)(PMe₃)] (R = alkyl, aryl) have been successfully synthesized from [Tp*RhH(CH₃)(PMe₃)]. The mechanism of formation of the [Tp*RhH(SR)(PMe₃)] complexes is proposed to involve the reductive elimination of methane, associatively induced by coordination of thiol. This mechanism is analogous to the mechanism proposed for alkyne hydrothiolation catalyzed by [Tp*Rh(PPh₃)₂]. Alkyne hydrothiolation reactions in the presence of [Tp*RhH(SR)(PMe₃)] are shown to produce the same product regioisomer as reactions catalyzed by [Tp*Rh(PPh₃)₂]. The synthesis of the vinyl sulfone-containing drug K777, currently in clinical trials for the treatment of Chagas disease, via alkyne hydrothiolation methodology catalyzed by [RhCl(PPh₃)₃], is reviewed. The methodology proves to be versatile in the synthesis of K777 and related analogues. The analogues are assessed in terms of their reactivity towards Michael addition as a method of predicting pharmacodynamics properties. The methanolic pKAs of a series of para-substituted aryl thiols are reported and correlated to their predicted aqueous pKA values. The Hammett dual parameter correlation to the experimental data reveals that the acidity constants are more dependent on the inductive effects of the para-substituent compared to the resonance effect. The dual parameter correlation also allows for the prediction of the methanolic and aqueous acidity constant of any para-substituted aryl thiol, as long as the substituent’s resonance and induction Hammett constants are known.

description: Intensity interferometry permits very long optical baselines and the observation of sub-milliarcsecond structures. Using planned kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial resolution achieved in optical astronomy by an order of magnitude, inviting detailed studies of the shapes of rapidly rotating hot stars with structures in their circumstellar disks and winds, or mapping out patterns of nonradial pulsations across stellar surfaces. Signal-to-noise in intensity interferometry favors high-temperature sources and emission-line structures, and is independent of the optical passband, be it a single spectral line or the broad spectral continuum. Prime candidate sources have been identified among classes of bright and hot stars. Observations are simulated for telescope configurations envisioned for large Cherenkov facilities, synthesizing numerous optical baselines in software, confirming that resolutions of tens of microarcseconds are feasible for numerous astrophysical targets.

description: Microalgae display features that render them perfect candidates for biotechnological products and industrial applications. Nevertheless, still, only a small number of them have been studied for their metabolic potential. Herein, we aim to contribute to microalgal metabolic diversity, including in the study of novel genera and species that are investigated for the first time. The intracellular content of 30 eukaryotic autochthonous microalgae belonging to Chlorophyta, Bacillariophyta, Chlorachniophyta, Ochrophyta, and Rhodophyta isolated from different environments in Greece was extracted with six different solvents and tested for their antimicrobial activity against five pathogenic bacterial strains; 50% of the extracts were found to inhibit the growth of the tested bacteria. Strains growing in standard culture conditions, without applying any stress, were examined for their cellular content using analytical methods. The protein and carbohydrate content of some strains was relatively high. We found strains that are worthy of further investigation to be used in commerce or as a potential material for biotechnology.

description: A Diretiva Quadro da Água (DQA) foi implementada na União Europeia em 2000 e gradualmente transposta para a legislação nacional dos Estados Membros. A DQA constituiu um importante avanço na proteção dos ecossistemas aquáticos superficiais, águas de transição e subterrâneas, tendo como objetivo atualmente que todas as massas de água atinjam a Boa qualidade ecológica, até 2027. No entanto, os procedimentos que permitem a monitorização e classificação das massas de água no âmbito da DQA são complexos e morosos. O presente artigo apresenta o enquadramento e a aplicação das metodologias de monitorização e classificação das massas de água de natureza lótica (p.ex. rios) de uma forma simplificada, contribuindo para melhorar a acessibilidade da sociedade em geral a esta informação, e consequentemente favorecendo a disseminação dos princípios e metodologias de monitorização associados à DQA. Este trabalho está focado especificamente em sistemas lóticos. Uma vez que a avaliação da qualidade da água sensu DQA considera a monitorização de comunidades biológicas e que as comunidades biológicas de maior importância indicadora são distintas entre diferentes tipos de ecossistemas aquáticos (p.ex. entre rios e albufeiras ou lagos), o enfoque foi definido para tornar o documento mais conciso. A informação aqui disponibilizada poderá servir como um suporte relevante para o desenvolvimento de estratégias de envolvimento da sociedade na implementação da DQA em Portugal, que se encontra ainda aquém do desejável.

description: In this article we develop a theoretical framework to study the hydrodynamic interactions in the presence of a non-flat and no-slip boundary. We calculate the influence of a small amplitude and sinusoidal deformations of a boundary wall in the self mobility and the two body hydrodynamic interactions for spherical particles. We show that the surface roughness enhances the self mobility of a sphere in a way that, for motion in front of a local hump of the surface, the mobility strength decreases while it increases for the motion above a local deep of the rough surface. The influence of the surface roughness in the two body hydrodynamic interactions is also analyzed numerically.

description: Companies demand academic graduates with much more than only professional competence. Methodological skills, social competence or creativity are just some keywords that are mentioned often. Many years academic education concentrated on teaching professional skills, but in changing business environments with increased competition, shorter time-to-market, higher quality demands and high cost sensitivity, graduates have to face novel work contexts, e.g. working in interdisciplinary project teams. The Karlsruhe Education Model for Product Development (KaLeP) addresses competence development beyond pure professional skills. This contribution briefly presents the KaLeP approach and gives deeper insight to the project work of the integrated product development course being a case study. Further on the authors discuss how students can develop key competencies in a realistic project environment. Two examples are teamwork and cooperation support. The contribution points out, how those competencies can be addressed and improved during a four-month project task.

description: We study dynamics of populations of resonantly coupled oscillators having different frequencies. Starting from the coupled van der Pol equations we derive the Kuramoto-type phase model for the situation, where the natural frequencies of two interacting subpopulations are in relation 2:1. Depending on the parameter of coupling, ensembles can demonstrate fully synchronous clusters, partial synchrony (only one subpopulation synchronizes), or asynchrony in both subpopulations. Theoretical description of the dynamics based on the Watanabe-Strogatz approach is developed.

description: We study numerically the depinning transition of driven elastic interfaces in a random-periodic medium with localized periodic-correlation peaks in the direction of motion. The analysis of the moving interface geometry reveals the existence of several characteristic lengths separating different length-scale regimes of roughness. We determine the scaling behavior of these lengths as a function of the velocity, temperature, driving force, and transverse periodicity. A dynamical roughness diagram is thus obtained which contains, at small length scales, the critical and fast-flow regimes typical of the random-manifold (or domain wall) depinning, and at large length-scales, the critical and fast-flow regimes typical of the random-periodic (or charge-density wave) depinning. From the study of the equilibrium geometry we are also able to infer the roughness diagram in the creep regime, extending the depinning roughness diagram below threshold. Our results are relevant for understanding the geometry at depinning of arrays of elastically coupled thin manifolds in a disordered medium such as driven particle chains or vortex-line planar arrays. They also allow to properly control the effect of transverse periodic boundary conditions in large-scale simulations of driven disordered interfaces.

description: Associated production of a baryonic Z' boson with the W boson can account for the excess in Wjj production observed by the CDF collaboration at the Tevatron. We analyze other possible channels of this Z' at the Tevatron and at the LHC, including γZ' and Z Z' with the Z' -> jj. We show that the chances of confirming this baryonic Z' is better at the Tevatron than at the LHC because of the faster growing backgrounds at the LHC. Unfortunately the current systematic uncertainties of the order of 10% cannot yield any significant excess in both γZ' and Z Z' channels at the Tevatron and also at the LHC. Nevertheless the search using the b\bar b decay mode of Z' is much more feasible at the LHC, provided that the branching ratio B(Z' -> b\bar b) > 0.1. In particular, the W Z' -> l νb\bar b mode has a signal-to-background ratio larger than 1. Even with 1 fb^{-1} luminosity at the LHC it can lead to a high significance level. The WZ' -> l νb \bar b and γZ' -> γb \bar b are also highly observable at the Tevatron.

description: We have performed an angle-resolved photoemission spectroscopy study of the new iron-based superconductor K0.8Fe1.7Se2 (Tc ~ 30 K). Clear band dispersion is observed with the overall bandwidth renormalized by a factor of 2.5 compared to our local density approximation calculations, indicating relatively strong correlation effects. Only an electronlike band crosses the Fermi energy, forming a nearly circular Fermi surface (FS) at M (π, 0). The holelike band at Γ sinks ~ 90 meV below the Fermi energy, with an indirect band gap of 30 meV to the bottom of the electronlike band. The observed FS topology in this superconductor favors (π, π) inter-FS scattering between the electronlike FSs at the M points, in sharp contrast with other iron-based superconductors which favor (π, 0) inter-FS scattering between holelike and electronlike FSs.

description: This is an “action research” project that makes scientific products necessary for conservation decision-making, while also applying additional methods to explore scientific frontiers. It is anticipated that the applied work will help the most locally, and the exploration of novel methods will help more with the global biodiversity challenge.
The applied conservation science assignment was to prioritize and map areas important for wildlife habitat connectivity within several regions in California: the Modoc Plateau, the Sacramento Valley, and the West Mojave Desert. These regions are important for alternative energy expansion in order to meet California’s ambitious plans to reduce greenhouse gas emissions by 2030. Identifying critical pathways for wildlife movement in these regions would help the state avoid or minimize impacts in these areas. In general, there are two ways to conserve connectivity in a region – (1) conserve more habitats in key areas that facilitate movement and (2) mitigate landscape features that impede movement, such as roads, railroads, and urban development. Our connectivity analysis results were used in combination with other conservation factors to answer these questions: what areas should be conserved or avoided? What areas may need mitigation for any kind of development?
In doing this action research, we explored three questions:How can we assist prioritization efforts by improving the way that connectivity models map conservation priority both within and among the linkages on the landscape?How can climate change considerations be better incorporated into habitat connectivity modeling and prioritization?How can the priority area maps for many focal species, and several structural (naturalness-based) connectivity analyses, be combined into a single map?

Alleviating the corporate social responsibility reporting-performance inconsistency : a tentative proposal of the "reflexive law plus" model
Creators: name: Hao, Si
Publisher: name: University of British Columbia
Year: 2017

description: The present research identifies corporate reporting-performance inconsistency as a major issue that undermines the current practice of corporate social responsibility (CSR). The inconsistency manifests in that companies either avoid disclosing negative information in their CSR reports or use vague and empty expressions to cover their CSR inaction. In most situations, instead of providing a complete and balanced picture and causing companies to re-examine their own CSR behaviour, CSR reporting has been declining into a strategic corporate communication tool that primarily serves firms’ own interests. Such a problem greatly challenges the fundamentals of CSR and raises hard questions as to the reliability of private regulation and corporate self-regulation pertaining to CSR reporting. Taking Canada as a field of research, the present study combines theoretical with empirical research methodology in order to thoroughly investigate the problem of the CSR reporting-performance inconsistency and provide a plausible solution to it from a law and regulation perspective. The main empirical research methods it takes are qualitative interviews and documentary analysis. In particular, the present research builds on the literature and empirical observations to explain the inconsistency and identify the regulatory gaps that currently exist in CSR reporting. As a side issue, it also questions the primary purpose of the CSR reporting regime, suggesting that CSR reporting should be used to transform irresponsible corporate performance and serve broader public goals. Inspired by the reflexive law literature and the empirical evidence, the present research develops a concrete model of “reflexive law plus” to address the CSR reporting-performance gap. “Reflexive law plus”, as named by the present research, is a refined form of reflexive law, in the sense that it is faithful to the fundamentals of the reflexive law theory, yet incorporates regulatory design components that can better catalyze and consolidate the self-referential capacity of the companies involved in CSR reporting. The present research holds that “reflexive law plus” provides a sound solution to remediate the inconsistency because it is pertinent to the regulatory circumstance in which CSR reporting is situated.
Quantum description and properties of electrons emitted from pulsed nanotip electron sources
Creators: name: Lougovski, Pavel

description: We present a quantum calculation of the electron degeneracy for electron sources. We explore quantum interference of electrons in the temporal and spatial domain and demonstrate how it can be utilized to characterize a pulsed electron source. We estimate effects of Coulomb repulsion on two-electron interference and show that currently available nano tip pulsed electron sources operate in the regime where the quantum nature of electrons can be made dominant.
Two-sphere low Reynold's propeller

Year: 2010
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

subject: FOS: Physical sciences

description: A three-dimensional model of a low-Reynold's swimmer is introduced and analyzed in this paper. This model consists of two large and small spheres connected by two perpendicular thin rods. The geometry of this system is motivated by the microorganisms that use a single tail to swim, the large sphere represents the head of microorganism and the small sphere resembles its tail. Each rod changes its length and orientation in a non-reciprocal manner that effectively propel the system. Translational and rotational velocities of the swimmer are studied for different values of parameters. Our findings show that by changing the parameters we can adjust both the velocity and the direction of motion of the swimmer.

Detailed study of dissipative quantum dynamics of K-2 attached to helium nanodroplets

description: We thoroughly investigate vibrational quantum dynamics of dimers attached to He droplets motivated by recent measurements with K-2 [1]. For those femtosecond pump-probe experiments, crucial observed features are not reproduced by gas phase calculations but agreement is found using a description based on dissipative quantum dynamics, as briefly shown in [2]. Here we present a detailed study of the influence of possible effects induced by the droplet. The helium droplet causes electronic decoherence, shifts of potential surfaces, and relaxation of wave packets in attached dimers. Moreover, a realistic description of (stochastic) desorption of dimers off the droplet needs to be taken into account. Step by step we include and study the importance of these effects in our full quantum calculation. This allows us to reproduce and explain all major experimental findings. We find that desorption is fast and occurs already within 2-10 ps after electronic excitation. A further finding is that slow vibrational motion in the ground state can be considered frictionless.

description: P53 is a tumour development p53. The aim of this work was to study the regulation of p53 in embryonic stem cells and its activation in response to DNA damage. p53 was found that p53 becomes transcriptionally active in ES cells after DNA damage.
Embryonic stem cells contain a relatively high amount of p53 protein and p53 RNA. After differentiation p53 level is rapidly downregulated. The high abundance of p53 in undifferentiated ES cells is a result of enhanced translation.
An outlier map for Support Vector Machine classification
Creators: name: Debruyne, Michiel
Publisher: name: arXiv
Year: 2010
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: Support Vector Machines are a widely used classification technique. They are computationally efficient and provide excellent predictions even for high-dimensional data. Moreover, Support Vector Machines are very flexible due to the incorporation of kernel functions. The latter allow to model nonlinearity, but also to deal with nonnumerical data such as protein strings. However, Support Vector Machines can suffer a lot from unclean data containing, for example, outliers or mislabeled observations. Although several outlier detection schemes have been proposed in the literature, the selection of outliers versus nonoutliers is often rather ad hoc and does not provide much insight in the data. In robust multivariate statistics outlier maps are quite popular tools to assess the quality of data under consideration. They provide a visual representation of the data depicting several types of outliers. This paper proposes an outlier map designed for Support Vector Machine classification. The Stahel--Donoho outlyingness measure from multivariate statistics is extended to an arbitrary kernel space. A trimmed version of Support Vector Machines is defined trimming part of the samples with largest outlyingness. Based on this classifier, an outlier map is constructed visualizing data in any type of high-dimensional kernel space. The outlier map is illustrated on 4 biological examples showing its use in exploratory data analysis.

description: In video games, virtual characters' decision systems often use a simplified representation of the world. To increase both their autonomy and believability we want those characters to be able to learn this representation from human players. We propose to use a model called growing neural gas to learn by imitation the topology of the environment. The implementation of the model, the modifications and the parameters we used are detailed. Then, the quality of the learned representations and their evolution during the learning are studied using different measures. Improvements for the growing neural gas to give more information to the character's model are given in the conclusion.

description: L’évaluation des performances est devenue une question critique dans les universités au Maroc, en raison de changements importants liés à l’augmentation des niveaux de concurrence, à l’accent mis sur l’amélioration continue des opérations des universités et autres établissements d’enseignement supérieur, aux nécessités de contrôler les coûts et d’améliorer la productivité, à la croissance de la demande quantitative et qualitative de ressources humaines basées sur la connaissance et les entrepreneurs, et l’intensification de la demande d’information pour aider les industries et les entreprises d’État à prendre des décisions stratégiques et tactiques appropriées (Farasatkhah, 2009) . De nombreuses méthodes et techniques ont été suggérées pour évaluer les performances dans les universités ou les établissements d’enseignement supérieur au fil des ans. Toutefois, des mesures financières bien connues, comme le Retour Sur Investissement (ROI), le Taux de Rentabilité Interne (TRI), la Valeur Actuelle Nette (VAN) et la période de récupération, se sont révélées inadéquates (Purbey et al., 2007) . Dans l’évaluation de la performance universitaire, il est essentiel de comprendre comment l’enseignement et la recherche contribuent aux objectifs organisationnels et stratégiques, et les méthodes d’évaluation qui reposent uniquement sur de simples mesures financières ne conviennent pas.
