description: We predict the existence of exchange broadening of optical lineshapes in disordered molecular aggregates and a nonuniversal disorder scaling of the localization characteristics of the collective electronic excitations (excitons). These phenomena occur for heavy-tailed Lévy disorder distributions with divergent second moments - distributions that play a role in many branches of physics. Our results sharply contrast with aggregate models commonly analyzed, where the second moment is finite. They bear a relevance for other types of collective excitations as well.

description: We perform a Monte Carlo simulation of two-dimensional N-step interacting self-avoiding walks at the theta point, with lengths up to N=3200. We compute the critical exponents, verifying the Coulomb-gas predictions, the theta-point temperature T_theta = 1.4986(11), and several invariant size ratios. Then, we focus on the geometrical features of the walks, computing the instantaneous shape ratios, the average asphericity, and the end-to-end distribution function. For the latter quantity, we verify in detail the theoretical predictions for its small- and large-distance behavior.

description: The danger of confusing long-range dependence with non-stationarity has been pointed out by many authors. Finding an answer to this difficult question is of importance to model time-series showing trend-like behavior, such as river run-off in hydrology, historical temperatures in the study of climates changes, or packet counts in network traffic engineering. The main goal of this paper is to develop a test procedure to detect the presence of non-stationarity for a class of processes whose $K$-th order difference is stationary. Contrary to most of the proposed methods, the test procedure has the same distribution for short-range and long-range dependence covariance stationary processes, which means that this test is able to detect the presence of non-stationarity for processes showing long-range dependence or which are unit root. The proposed test is formulated in the wavelet domain, where a change in the generalized spectral density results in a change in the variance of wavelet coefficients at one or several scales. Such tests have been already proposed in \cite{whitcher:2001}, but these authors do not have taken into account the dependence of the wavelet coefficients within scales and between scales. Therefore, the asymptotic distribution of the test they have proposed was erroneous; as a consequence, the level of the test under the null hypothesis of stationarity was wrong. In this contribution, we introduce two test procedures, both using an estimator of the variance of the scalogram at one or several scales. The asymptotic distribution of the test under the null is rigorously justified. The pointwise consistency of the test in the presence of a single jump in the general spectral density is also be presented. A limited Monte-Carlo experiment is performed to illustrate our findings.

Accelerating an iterative Helmholtz solver using reconfigurable hardware

Publisher: name: University of British Columbia

description: An implementation of seismic wave simulation on a platform consisting of a conventional host processor and a reconfigurable hardware accelerator is presented. This research is important in the field of exploration for oil and gas resources, where a 3D model of the subsurface of the Earth is frequently required. By comparing seismic data collected in a real-world survey with synthetic data generated by simulated waves, it is possible to deduce such a model. However this requires many time-consuming simulations with different Earth models to find the one that best fits the measured data. Speeding up the wave simulations would allow more models to be tried, yielding a more accurate estimate of the subsurface. The reconfigurable hardware accelerator employed in this work is a field programmable gate array (FPGA). FPGAs are computer chips that consist of electronic building blocks that the user can configure and reconfigure to represent their algorithm in hardware. Whereas a traditional processor can be viewed as a pipeline for processing instructions, an FPGA is a pipeline for processing data. The chief advantage of the FPGA is that all the instructions in the algorithm are already hardwired onto the chip. This means that execution time depends only on the amount of data to be processed, and not on the complexity of the algorithm. The main contribution is an implementation of the well-known Kaczmarz row projection algorithm on the FPGA, using techniques of dataflow programming. This kernel is used as the preconditioning step of CGMN, a modified version of the conjugate gradients method that is used to solve the time-harmonic acoustic isotropic constant density wave equation. Using one FPGA-based accelerator, the current implementation allows seismic wave simulations to be performed over twice as fast, compared to running on one Intel Xeon E5-2670 core. I also discuss the effect of modifications of the algorithm necessitated by the hardware on the convergence properties of CGMN. Finally, a specific plan for future work is set-out in order to fully exploit the accelerator platform, and the work is set in its larger context.

We have shown that the equation of state of spin polarized SQM is stiffer than that of the unpolarized case. We have also computed the structure properties of the spin polarized strange quark star (SQS) and have found that the presence of magnetic field leads to a more stable SQS compared to the unpolarized SQS.

description: Given an observed gravitational lens mirage produced by a foreground deflector (cf. galaxy, quasar, cluster,...), it is possible via numerical lens inversion to retrieve the real source image, taking full advantage of the magnifying power of the cosmic lens. This has been achieved in the past for several remarkable gravitational lens systems. Instead, we propose here to invert an observed multiply imaged source directly at the telescope using an ad-hoc optical instrument which is described in the present paper. Compared to the previous method, this should allow one to detect fainter source features as well as to use such an optimal gravitational lens telescope to explore even fainter objects located behind and near the lens. Laboratory and numerical experiments illustrate this new approach.

description: The Belleplaine test site, located in the island of Guadeloupe (French Lesser Antilles) includes a three-accelerometer vertical array, designed for liquefac- tion studies. The seismic response of the soil column at the test site is computed using three methods: the spectral ratio method using the vertical array data, a numerical method using the geotechnical properties of the soil column, and an operative fre- quency domain decomposition (FDD) modal analysis method. The Belleplaine test site is characterized by a mangrove layer overlaid by a stiff sandy deposit. This con- figuration is widely found at the border coast of the Caribbean region, which is exposed to high seismic hazard. We show that the buried mangrove layer plays the role of an isolation system equivalent to those usually employed in earthquake engineering aimed at reducing the seismic shear forces by reducing the internal stress within the structure. In our case, the flexibility of the mangrove layer reduces the distortion and the stress in the sandy upper layer, and consequently reduces the potential of liquefaction of the site.

description: We study the formation dynamics of a spontaneous ferromagnetic order in single self-assembled CdMnTe quantum dots. By measuring time-resolved photoluminescence, we determine the formation times for QDs with Mn ion contents x varying from 0.01 to 0.2. At low x these times are orders of magnitude longer than exciton spin relaxation times evaluated from the decay of photoluminescence circular polarization. This allows us to conclude that the direction of the spontaneous magnetization is determined by a momentary Mn spin fluctuation rather than resulting from an optical orientation. At higher x, the formation times are of the same order of magnitude as found in previous studies on higher dimensional systems. We also find that the exciton spin relaxation accelerates with increasing Mn concentration.

description: Information distributed through the Web keeps growing faster day by day, and for this reason, several techniques for extracting Web data have been suggested during last years. Often, extraction tasks are performed through so called wrappers, procedures extracting information from Web pages, e.g. implementing logic-based techniques. Many fields of application today require a strong degree of robustness of wrappers, in order not to compromise assets of information or reliability of data extracted. Unfortunately, wrappers may fail in the task of extracting data from a Web page, if its structure changes, sometimes even slightly, thus requiring the exploiting of new techniques to be automatically held so as to adapt the wrapper to the new structure of the page, in case of failure. In this work we present a novel approach of automatic wrapper adaptation based on the measurement of similarity of trees through improved tree edit distance matching techniques.

description: In the area of traditional physics the atomic nucleus belongs to the most complex systems. It involves essentially all elements that characterize complexity including the most distinctive one whose essence is a permanent coexistence of coherent patterns and of randomness. From a more interdisciplinary perspective, these are the financial markets that represent an extreme complexity. Here, based on the matrix formalism, we set some parallels between several characteristics of complexity in the above two systems. We, in particular, refer to the concept - historically originating from nuclear physics considerations - of the random matrix theory and demonstrate its utility in quantifying characteristics of the coexistence of chaos and collectivity also for the financial markets. In this later case we show examples that illustrate mapping of the matrix formulation into the concepts originating from the graph theory. Finally, attention is drawn to some novel aspects of the financial coherence which opens room for speculation if analogous effects can be detected in the atomic nuclei or in other strongly interacting Fermi systems.

description: We present three transits of GJ 1214b, observed as part of the Apache Point Observatory Survey of Transit Lightcurves of Exoplanets (APOSTLE). We used APOSTLE r-band lightcurves in conjunction with previously gathered data of GJ 1214b to re-derive system parameters. By using parameters such as transit duration and ingress/egress length we are able to reduce the degeneracies between parameters in the fitted transit model, which is a preferred condition for Markov Chain Monte Carlo techniques typically used to quantify uncertainties in measured parameters. The joint analysis of this multi-wavelength dataset confirms earlier estimates of system parameters including planetary orbital period, the planet-to-star radius ratio and stellar density. We fit the photometric spectralenergy distribution of GJ 1214 to derive stellar luminosity, which we then use to derive its absolute mass and radius. From these derived stellar properties and previously published radial velocity data we were able to refine estimates of the absolute parameters for the planet GJ 1214b. Transit times derived from our study show no evidence for strong transit timing variations. Some lightcurves we present show features that we believe are due to stellar activity. During the first night we observed a rise in the out-of-eclipse flux of GJ 1214 with a characteristic fast-rise exponential decay shape commonly associated with stellar flares. On the second night we observed a minor brightening during transit, which we believe might have been caused by the planet obscuring a star-spot on the stellar disk.

description: Nowadays, the huge amount of information distributed through the Web motivates studying techniques to be adopted in order to extract relevant data in an efficient and reliable way. Both academia and enterprises developed several approaches of Web data extraction, for example using techniques of artificial intelligence or machine learning. Some commonly adopted procedures, namely wrappers, ensure a high degree of precision of information extracted from Web pages, and, at the same time, have to prove robustness in order not to compromise quality and reliability of data themselves. In this paper we focus on some experimental aspects related to the robustness of the data extraction process and the possibility of automatically adapting wrappers. We discuss the implementation of algorithms for finding similarities between two different version of a Web page, in order to handle modifications, avoiding the failure of data extraction tasks and ensuring reliability of information extracted. Our purpose is to evaluate performances, advantages and draw-backs of our novel system of automatic wrapper adaptation.

description: The experimental data of N. Takahashi, Y. Hanyu, T. Musha, R. Kubo, and G. Matsumoto, Physica D \textbf{43}, 318 (1990), on the response of squid giant axons stimulated by periodic sequence of short current pulses is interpreted within the Hodgkin-Huxley model. The minimum of the firing rate as a function of the stimulus amplitude $I_0$ in the high-frequency regime is due to the multimodal transition. Below this singular point only odd multiples of the driving period remain and the system is highly sensitive to noise. The coefficient of variation has a maximum and the firing rate has a minimum as a function of the noise intensity which is an indication of the stochastic coherence antiresonance. The model calculations reproduce the frequency of occurrence of the most common modes in the vicinity of the transition. A linear relation of output frequency vs. $I_0$ for above the transition is also confirmed.

Good riddance to bad proteins : identification of novel protein quality control pathways targeting cytosolic misfolded proteins for degradation
Creators: name: Fang, Neng
Publisher: name: University of British Columbia
Year: 2015

description: Protein misfolding is cytotoxic and the accumulation of misfolded proteins threatens cell fitness and viability. Failure to eliminate these polypeptides has been associated with numerous diseases including neurodegenerative disorders. The ubiquitin proteasome system is a major pathway that degrades in the cell these unwanted proteins targeted by protein quality control. Several distinct protein quality control degradation pathways that employ different ubiquitin ligases have been discovered in recent years. Here, we present two novel protein quality control degradation pathways that require the ubiquitin ligases Hul5 and Rsp5 to target cytosolic misfolded proteins for degradation. We used quantitative mass spectrometry to determine that in Saccharomyces cerevisiae, heat-shock triggered a large increase in the level of ubiquitylation of mainly cytosolic proteins. We discovered that the Hul5 ubiquitin ligase participated in this ubiquitylation response. Hul5 was required to maintain cell fitness after heat-shock and to degrade short-lived misfolded proteins. In addition, the localization of Hul5 in the cytoplasm was important for its quality control function. We also showed that Hul5 targeted low-solubility cytosolic proteins in both heat-shock and unstressed conditions. These data indicate that Hul5 is involved in the degradation of cytosolic misfolded proteins. Beside the Hul5 pathway, we found that Rsp5 ubiquitin ligase also participated in the increase of ubiquitylation levels upon heat-shock. Our results indicated that Rsp5 employed a bipartite recognition mechanism to ubiquitylate heat-induced cytosolic targets via the interaction with the Hsp40 co-chaperone Ydj1 and the PY-motifs primarily found in structured regions of these proteins. Notably, we also found that the Rsp5-dependent pathway was dependent on both Ubp2 and Ubp3 deubiquitinases, which acted to mainly reduce the levels of K63-linked ubiquitin chains conjugated to cytosolic misfolded proteins upon heat-shock. The absence of either deubiquitinase led to reduced cell fitness under stress conditions underscoring the importance of the Rsp5-dependent pathway. All together, we identified the two major yeast ubiquitin ligases that mediated the increase in ubiquitylation of cytosolic misfolded proteins upon heat stress. Our work shed new light on protein quality control and how the cell can mediate the degradation of misfolded proteins.
Geistige Behinderung und psychische Störung: Begleitung von Menschen mit einer Doppeldiagnose in Wohngruppen für Menschen mit einer geistigen Behinderung

description: Bei Menschen mit einer geistigen Behinderung wird die Prävalenz psychischer Erkrankungen auf insgesamt 30–50% geschätzt. Vergleichsweise liegt die Prävalenz psychischer Störungen bei der Normalbevölkerung bei 10%, woraus festgestellt werden kann, dass Menschen mit einer geistigen Behinderung ein drei bis fünf Mal höheres Risiko aufweisen, an psychischen Störungen zu erkranken (Anton Došen, 2018, S. 16). Menschen mit einer sogenannten Doppeldiagnose weisen herausfordernde Verhaltensweisen auf, die von ihren Mitmenschen nur schwer zu deuten sind und die Begleitung somit erschweren (Pia Bienstein & Peter Weber, 2014, S. 13). Jedoch gibt es zu wenige spezialisierte Angebote für diese Personengruppe, weshalb sie oftmals in Institutionen der Behindertenhilfe untergebracht werden, was bei den Fachpersonen zu Herausforderungen und Überforderungen führt (Bienstein & Weber, 2014, S. 326). Die Autorinnen gehen in der vorliegenden Arbeit somit der Frage nach, welchen Herausforderungen und Chancen Fachpersonen der Behindertenhilfe bezüglich der Begleitung von Menschen mit einer Doppeldiagnose begegnen und wie das Angebot angepasst werden sollte, um eine vollumfängliche und adäquate Begleitung dieser Personengruppe zu gewährleisten. Aufgrund der Gruppendiskussionen mit Teams von Wohngruppen für Menschen mit einer geistigen Behinderung geht hervor, dass eine Zunahme von Menschen mit einer Doppeldiagnose auf solchen Wohngruppen beobachtet wird und dies Herausforderungen für die Fachpersonen mit sich bringt. Es wird deutlich, dass diese Institutionen grundsätzlich gute Voraussetzungen für die Begleitung dieser Personengruppe mit sich bringen, dennoch ist zu erkennen, dass eine Anpassung des bestehenden Angebotes unausweichlich ist. Mögliche Veränderungsvorschläge werden in dieser Arbeit aufgeführt und sollen als Anregungen für Fachpersonen der Sozialen Arbeit, der Psychiatrie sowie für Betroffene und Angehörige dienen.

description: A generic quantum channel can be represented in terms of a unitary interaction between the information-carrying system and a noisy environment. Here, the minimal number of quantum Gaussian environmental modes required to provide a unitary dilation of a multi-mode bosonic Gaussian channel is analyzed both for mixed and pure environment corresponding to the Stinespring representation. In particular, for the case of pure environment we compute this quantity and present an explicit unitary dilation for arbitrary bosonic Gaussian channel. These results considerably simplify the characterization of these continuous-variable maps and can be applied to address some open issues concerning the transmission of information encoded in bosonic systems.

description: This study evaluated the importance of sustainable development competence for the civil engineering industry in British Columbia, Canada. Two central research questions were addressed. What is the current civil engineering industry understanding of sustainable development in the areas of knowledge, skills and attitudes? How important are sustainable development competencies for new engineering graduates, and how does this differ across various sectors? Data were collected from semi-structured interviews of sustainable development practitioners and the administration of a province-wide industry survey. The survey received qualified responses from industry representatives across multiple subdisciplines. The results of the research study have similar findings to previous research studies of sustainable development competence. Practitioners view engineering design, systems thinking and interdisciplinary teamwork as critical areas of competence. Discipline and firm size can contribute to significant level of importance for various competence areas. Two major themes emerged from the semi-structured interviews. These were categorized as mentorship and reputation, and were described as guiding principles of engineering practice. Minor themes were also noted, and included importance of communication and collaboration across engineering practice. Participants of both the interviews and survey indicated a growing concern for the work readiness of new Engineering graduates while remaining optimistic for the engineering profession. The diverse sustainable development competencies required of the civil engineering profession is cause for a re-examination of the civil engineering curriculum in Canada. There is evidence to suggest that students are facing a large learning curve entering the profession due to inadequate training course opportunities at the undergraduate level. Higher education institutions should be finding solutions to bridge the gap between industry and accreditation expectations of engineering graduates. Engineering education must adapt to meet the demands of the engineering profession as it continues to prioritize sustainable development as a fundamental requirement of engineering activities.

description: We present two newly-discovered compact elliptical (cE) galaxies, exhibiting clear evidence of tidal steams, and found during a search of SDSS DR7 for cE candidates. The structural parameters of the cEs are derived using GALFIT, giving effective radii, Re, of 388 and 263 parsecs, and B-band mean surface brightnesses within Re of 19.4 and 19.2 magnitudes per arcsec squared. We have re-analysed the SDSS spectra, which indicate that they possess young to intermediate-age stellar populations. These two cEs provide direct evidence, a "smoking gun", for the process of tidal stripping that is believed to be the origin of M32-type galaxies. Both are in small groups with a large spiral fraction, suggesting that we may be seeing the formation of such cE galaxies in dynamically young environments. The more compact of the galaxies is found in a small group not unlike the Local Group, and thus provides an additional model for understanding M32.

description: Exotic $^8$Be and $^{12}$C decays from high-lying resonances in $^{24}$Mg are analyzed in terms of a cluster model. The calculated quantities agree well with the corresponding experimental data. It is found that the calculated decay widths are very sensitive to the angular momentum carried by the outgoing cluster. It is shown that this property makes cluster decay a powerful tool to determine the spin as well as the molecular structures of the resonances.

description: We describe the reduction of data taken with the PACS instrument on board the Herschel Space Observatory in the Science Demonstration Phase of the Herschel-ATLAS (H-ATLAS) survey, specifically data obtained for a 4x4-deg^2 region using Herschel's fast-scan (60 arcsec/s) parallel mode. We describe in detail a pipeline for data reduction using customised procedures within HIPE from data retrieval to the production of science-quality images. We found that the standard procedure for removing Cosmic-Ray glitches also removed parts of bright sources and so implemented an effective two-stage process to minimise these problems. The pronounced 1/f noise is removed from the timelines using 3.4- and 2.5-arcmin boxcar high-pass filters at 100 and 160-um. Empirical measurements of the point-spread function (PSF) are used to determine the encircled energy fraction as a function of aperture size. For the 100- and 160-um bands, the effective PSFs are ~9 and ~13 arcsec (FWHM), and the 90-per-cent encircled energy radii are 13 and 18 arcsec. Astrometric accuracy is good to ~<2 arcsec. The noise in the final maps is correlated between neighbouring pixels and rather higher than advertised prior to launch. For a pair of cross-scans, the 5-sigma point-source sensitivities are 125-165 mJy for 9-13-arcsec radius apertures at 100-um and 150-240 mJy for 13-18-arcsec radius apertures at 160-um.
Collective responsibility and democratic practice
Creators: name: Tian, Jie (TJ)

description: Questions of responsibility lie at the very heart of most social and political controversies. Responsibility attribution becomes rather complicated when it comes to social activities, in which members of a group share agency in collective actions or practices, even though these members may not participate directly in the outcome of such actions and the contribution of any single member to that outcome is negligible. The general tendency to individualize and to psychologize human actions makes it difficult to understand how collectives, such as companies, families and nations, can or should take responsibility for their actions. Philosophical attempts have been made to make sense of the concept of collective responsibility. Following these philosophers, I intend to develop some guiding principles for investigating collective responsibility and to explain how these principles reshape our general understanding of responsibility and public life. These principles of understanding collective responsibility have the potential to affect the practice of collective decisions making. Political decision-making by citizen participants in a democratic process is taken as a paradigm case of collective actions. I will defend a deliberative model of democratic practice as the most promising one in assisting citizen participants in recognizing that they will be invested with shared responsibility of the political community. A deliberative model not only helps citizen participants gain deliberative capacity and become more responsive to reasons, it also helps participants to see the shared nature of collective decisions.
Coupling of polaritons to vibrational modes of ultracold atoms in an optical lattice

description: The coupling of internal electronic excitations to vibrational modes of the external motion of ultracold atoms in an optical lattice is studied here in using a perturbation expansion in small atomic displacements. In the Mott insulator case with one atom per site, the resonance dipole-dipole coupling between neighboring sites can induce emission and absorption of vibrational quanta. Within a cavity in the strong exciton-photon coupling regime such coupling results in polariton-vibration interactions, which create a significant thermalization mechanism for polaritons toward their minimum energy, and leading to motional heating of the lattice atoms.

description: The dual attainment of the Monge--Kantorovich transport problem is analyzed in a general setting. The spaces $X, Y$ are assumed to be polish and equipped with Borel probability measures $μ$ and $ν$. The transport cost function $c:\XY \to [0,\infty]$ is assumed to be Borel measurable. We show that a dual optimizer always exists, provided we interpret it as a projective limit of certain finitely additive measures. Our methods are functional analytic and rely on Fenchel's perturbation technique.
Liquid-solid interaction at nanoscale and its application in vegetal biology

description: The water ascent in tall trees is subject to controversy: the vegetal biologists debate on the validity of the cohesion-tension theory which considers strong negative pressures in microtubes of xylem carrying the crude sap. This article aims to point out that liquids are submitted at the walls to intermolecular forces inferring density gradients making heterogeneous liquid layers and therefore disqualifying the Navier-Stokes equations for nanofilms. The crude sap motion takes the disjoining pressure gradient into account and the sap flow dramatically increases such that the watering of nanolayers may be analogous to a microscopic flow. Application to microtubes of xylem avoids the problem of cavitation and enables us to understand why the ascent of sap is possible for very high trees.
description: 16 pages 1 figure New modern concept of the sap ascent in high trees taking into account the disjoining pressure in nanofilms of liquids. The motion of the sap is related to thin films slippering on the xylem walls

description: As a powerful statistical image modeling technique, sparse representation has been successfully used in various image restoration applications. The success of sparse representation owes to the development of l1-norm optimization techniques, and the fact that natural images are intrinsically sparse in some domain. The image restoration quality largely depends on whether the employed sparse domain can represent well the underlying image. Considering that the contents can vary significantly across different images or different patches in a single image, we propose to learn various sets of bases from a pre-collected dataset of example image patches, and then for a given patch to be processed, one set of bases are adaptively selected to characterize the local sparse domain. We further introduce two adaptive regularization terms into the sparse representation framework. First, a set of autoregressive (AR) models are learned from the dataset of example image patches. The best fitted AR models to a given patch are adaptively selected to regularize the image local structures. Second, the image non-local self-similarity is introduced as another regularization term. In addition, the sparsity regularization parameter is adaptively estimated for better image restoration performance. Extensive experiments on image deblurring and super-resolution validate that by using adaptive sparse domain selection and adaptive regularization, the proposed method achieves much better results than many state-of-the-art algorithms in terms of both PSNR and visual perception.
