description: No abstracts are to be cited without prior reference to the author.For pelagic fish, schools are generally considered to be the unit of spatio-temporal aggregation. At sea, schools are generally observed in clusters of schools. This meso-scale structure is not well known but its biological importance both for acoustic surveys and fishery exploitation is believed critical. The present paper attempts to give a methodology to characterise clusters of schools and studies the variations in cluster parameters over the years. Schools have been extracted from echograms of historical acoustic surveys in Senegal. Clusters of schools are defined by an algorithm which groups the schools in clusters inside which the school occurrence is as homogeneous as possible (Poisson occurrence). The parameters which caracterise the clsuters of schools are : Length and number of clusters, number of schools per unit length inside the clusters, number of solitary schools outside clusters. Inter-annual variations in these parameters are analysed and related to the variations of the population abundance in the historical series. The method used is PCA with added passive variables. Population abundance was found to be. correlated to the area occupied by school clusters and to the total number of schools which is not new. New results are that population abundance was found correlated to the number of schools per unit length inside the clusters but uncorrelated to clusters average length and number.

description: No abstracts are to be cited without prior reference to the author.Abundance indices of young fish in the North Sea derived from the International Bottom Trawl Survey (IBTS) show large interannual fluctuations, which are not in accordance with ICES assessments in every case. The standard estimation of the abundance indices, however, does not explicitly account for potential influences of environmental variables on the spatial aggregation of juvenile fish and the probability distribution of the catches. The present study aims at improving the analysis and the estimation procedures for IBTS abundance indices. Variability of bottom trawl catches of age I and 2 whiting and cod was studied on three spatial scales: at fixed stations, within statistical rectangles and within the species-specific standard areas used in the IBTS. Daylight period, temperature, salinity, water depth and bottom type were considered as potential environmental variables influencing the catches; At fixed stations significant differences between day and night catches were found. Variability within rectangles increased with the degree of heterogeneity in the environment, where the effects of temperature and depth were most pronounced. Frequency distributions of the average catch by rectangle always deviate· substantially from normal distributions. Lognormal-based Generalized Linear Models for whiting and Delta-lognormal models for cod revealed that temperature and, in particular, depth contribute significantly to the variability also between rectangles. It is further demonstrated that depth can be used as a covariate in the estimation of abundance indices for the species-specific standard areas.

description: We present new spectrophotometric and spectropolarimetric observations of Mrk 1239, one of the 8 prototypes that defines type-1 narrow-line Seyfert galaxies (NLS1s). Unlike the other typical NLS1s though, a high degree of polarization ($P\sim$5.6%) and red optical-IR ($g-W_4$ = 12.35) colors suggest that Mrk 1239 is more similar to type-2 active galactic nuclei like NGC 1068. Detailed analysis of spectral energy distribution in the UV-optical-IR yields two components from the nucleus: a direct and transmitted component that is heavily obscured ($E_{B-V} \approx 1.6$), and another indirect and scattered one with mild extinction ($E_{B-V} \sim$ 0.5). Such a two-light-paths scenario is also found in previous reports based on the X-ray data. Comparison of emission lines and the detection of He\,{\footnotesize I}*$λ$10830 BAL at [-3000,-1000] km s$^{-1}$ indicates that the obscuring clouds are at physical scale between the sublimation radius and that of the narrow emission line regions. The potential existence of powerful outflows is found as both the obscurer and scatterer are outflowing. Similar to many other type-2s, jet-like structure in the radio band is found in Mrk 1239, perpendicular to the polarization angle, suggesting polar scattering. We argue that Mrk 1239 is very probably a type-2 counterpart of NLS1s. The identification of 1 out of 8 prototype NLS1s as a type-2 counterpart implies that there can be a substantial amount of analogs of Mrk 1239 misidentified as type-1s in the optical band. Properties of these misidentified objects are going to be explored in our future works.

description: Optimization problems over compact Lie groups have been extensively studied due to their broad applications in linear programming and optimal control. This paper analyzes least square problems over a noncompact Lie group, the symplectic group $\Sp(2N,\R)$, which can be used to assess the optimality of control over dynamical transformations in classical mechanics and quantum optics. The critical topology for minimizing the Frobenius distance from a target symplectic transformation is solved. It is shown that the critical points include a unique local minimum and a number of saddle points. The topology is more complicated than those of previously studied problems on compact Lie groups such as the orthogonal and unitary groups because the incompatibility of the Frobenius norm with the pseudo-Riemannian structure on the symplectic group brings significant nonlinearity to the problem. Nonetheless, the lack of traps guarantees the global convergence of local optimization algorithms.

description: The modular operator approach of Tomita-Takesaki to von Neumann algebras is elucidated in the algebraic structure of certain supersymmetric quantum mechanical systems. A von Neumann algebra is constructed from the operators of the system. An explicit operator characterizing the dual infinite degeneracy structure of a supersymmetric two dimensional system is given by the modular conjugation operator. Furthermore, the entanglement of formation for these supersymmetric systems using concurrence is shown to be related to the expectation value of the modular conjugation operator in an entangled bi-partite supermultiplet state thus providing a direct physical meaning to this anti-unitary, anti-linear operator as a quantitative measure of entanglement. Finally, the theory is applied to the case of two-dimensional Dirac fermions, as is found in graphene, and a supersymmetric Jaynes Cummings Model.

A multigrid method for determining the deflection of lithospheric plates
Creators: name: Carter, Paul M.
Publisher: name: University of British Columbia
Year: 2010

description: Various models are currently in existence for determining the deflection of lithospheric plates under an applied transverse load. The most popular models treat lithospheric plates as thin elastic or thin viscoelastic plates. The equations governing the deflection of such plates have been solved successfully in two dimensions using integral transform techniques. Three dimensional models have been solved using Fourier Series expansions assuming a sinusoidal variation for the load and deflection. In the engineering context, the finite element technique has also been employed. The current aim, however, is to develop an efficient solver for the three dimensional elastic and viscoelastic problems using finite difference techniques. A variety of loading functions may therefore be considered with minimum work involved in obtaining a solution for different forcing functions once the main program has been developed. The proposed method would therefore provide a valuable technique for assessing new models for the loading of lithospheric plates as well as a useful educational tool for use in geophysics laboratories. The multigrid method, which has proved to be a fast, efficient solver for elliptic partial differential equations, is examined as the basis for a solver of both the elastic and viscoelastic problems. The viscoelastic problem, being explicitly time-dependent, is the more challenging of the two and will receive particular attention. Multigrid proves to be a very effective method applicable to the solution of both the elastic and viscoelastic problems.

description: No abstracts are to be cited without prior reference to the author.The spatial distribution of small pelagic fish populations may be considered as dynamic patch mosaics. These are generated and maintained by processes of patch formation, development and disappearance. Several mechanisms drive space-time variations in abundance. Their increased understanding should greatly improve empirical sampling designs for estimation of demographic parameters. The level of fish aggregation (biomass per school, number of schools in a patch, number of patches and their dimensions) determines both precision of acoustic surveys and catchability in the fishery.

description: The hyperspherical adiabatic expansion is combined with complex scaling and used to calculate the energy distributions of the particles arising from three-body decaying low-lying $^{12}$C resonances. The large distance continuum properties of the wavefunctions are crucial and must be accurately calculated. The substantial changes from small to large distances determine the decay mechanisms. We illustrate by computing the energy distributions from decays of the $1^{-}$, $2^-$ and $4^{-}$-resonances in $^{12}$C. These states are dominated by sequential ($1^-$), through the $^{8}$Be ground state, and direct ($2^-$, $4^-$) decays.

description: Cu(In,Ga)Se2 (CIGSe)-based solar cells are promising candidates for efficient sunlight harvesting. However, their complex composition and microstructure can change under operation conditions, for instance heating from sun light illumination can lead to a degradation in performance. Here, we investigate the thermally-induced degradation processes in a set of CIGSe-based solar cells that were annealed at temperatures between 150C and 300C. Using correlative atom probe tomography (APT)/transmission electron microscope (TEM), we found that the buffer-absorber interface is not sharp but consists of an interfacial zone (2 - 6.5 nm wide) where a gradient of constituent elements belonging to the CdS buffer and CIGSe absorber appears. An enhanced short-range Cd in-diffusion inside the CIGSe was observed whenever a low Ga/(Ga+In) ratio occurred at the interface. This might indicate the presence of Ga vacancies as a channeling defect for Cd in-diffusion inside the CIGSe layer leading to a buried pn-homojunction. We evidence that a considerable amount of Cd is found inside the CIGSe layer at annealing temperatures higher than 150C. Further investigations of the elemental redistribution inside the CIGSe layer combined with C-V measurements support the formation of CdCu donor like defects deep inside the p-type CIGSe which lead to a strong compensation of the CIGSe layer and hence to strong deterioration of cell efficiency at annealing temperatures higher than 200C. Hence, understanding the degradation processes in Cu(In,Ga)Se2 (CIGSe)-based solar cells opens new opportunities for further improvement of the long-term device performance.
Linked $\mathcal{PT }$-symmetry to Supersymmetry in a class of non-Hermitian Hamiltonians

Year: 2008

description: We introduce and study a class of non-Hermitian Hamiltonians which have velocity dependent potentials. Since stability can not be advocated directly from the classical potential, we show that the energy spectra are real and bounded from below which proves the stability of the spectra of all members in the class. We find that the introduced class of non-Hermitian Hamiltonians do have a corresponding superpartner class of non-Hermitian Hamiltonians. We were able to introduce supercharges which in conjunction with the corresponding super Hamiltonians constitute a closed super algebra. Among the introduced Hamiltonians, we show that non-$\mathcal{PT }$-symmetric Hamiltonians can be transformed into their corresponding superpartner Hamiltonians via a specific canonical transformation while the $\mathcal{PT }$-symmetric ones failed to be mapped to their corresponding superpartner Hamiltonians via the same canonical transformation. Since canonical transformations preserve the spectrum, we conclude that non-$\mathcal{PT }$-symmetric Hamiltonians out of the introduced class of Hamiltonians have the same spectrum as the corresponding superpartner Hamiltonians and thus Susy is broken for such Hamiltonians. This kind of intertwining of $\mathcal{PT }$-symmetry and Supersymmetry is new as all the so far discussed cases concentrate on Hamiltonians of broken $\mathcal{PT }% $-symmetry that have broken Supersymmetry too while we showed that Susy can be also broken for non-$\mathcal{PT }$-symmetric and non-Hermitian Hamiltonians .

description: No abstracts are to be cited without prior reference to the author.Abundance estimates and cartography by species from acoustic surveys depend on the ability to identify echotraces. This is usually done by relating an echotrace to the presence of a specie. Such relation is either based on empirical knowledge or on mid-water trawl catches. The object of this paper is to model in a probabilistic way the relation between trawl catches and echogram aspect to improve acuteness of cartography and try in the future to estimate a species identification error Variance.

We numerically solve the TDOEP integral equation for the real-time nonlinear intersubband electron dynamics in a semiconductor quantum well with two occupied subbands. By comparison with adiabatic approximations, it is found that memory effects in the exact exchange potential become significant when the electron dynamics takes place in the vicinity of intersubband resonances.

Supervisory computer control of a flexible manufacturing cell
Creators: name: Kean, Thomas Maxwell
Publisher: name: University of British Columbia
Year: 2010

description: A combined software and hardware package has been developed which coordinates the activities of a Unimation PUMA 560 industrial robot and an ORAC CNC training lathe in a Flexible Manufacturing Cell environment under the supervision of a DEC VAX 11/750 computer. The hardware component is used to provide an intermediate interface between the VAX 11/750 software and the standard manual controls of the ORAC lathe. The interface to the PUMA robot is strictly software oriented and makes use of the Supervisor communication protocol provided by the robot's VAL II controller. The software package has been designed as a hierarchial, multi-tasking system to facilitate modular development and a logical division of labour. The hierarchy consists of three main levels, with the individual machine controllers providing the lowest level. At the middle layer is a number of subprocesses which execute on the VAX 11/750 and are each responsible for the direct supervision of one machine controller. This supervision involves both sending commands and receiving status messages in the native language of the individual controllers. At the top layer of the hierarchy is a single process which is responsible for the overall coordination of the workcell activities. Each subtask in the hierarchy communicates with its vertical neighbours through a series of communication protocols and command vocabularies developed for that purpose. Each subtask is also provided with a structured interface to the operator's console. This interface is implemented by a separate VAX process that provides a status window environment for each machine that is active in the cell, but also intercepts text messages and prompts so that they may be displayed to the operator one at a time. Two different software packages have been developed for the top layer of the hierarchy. The ORCAM package is dedicated to the task of automatically manufacturing turned components from a CAD database. The FMC package provides a flexible interface to each of the supported machines and may be used to supervise any number of user-defined tasks.

description: We discuss the geometry of the highly quantal nuclear three-body systems composed of a core plus two loosely bound particles. These Borromean nuclei have no single bound two-body subsystem. Correlation plays a prominent role. From consideration of the $B(E1)$ value extracted from electromagnetic dissociation, in conjunction with HBT-type analysis of the two valence-halo particles correlation, we show that an estimate of the over-all geometry can be deduced. In particular we find that the opening angle between the two neutrons in $^{6}$He and $^{11}$Li are, respectively, $θ_{nn} = {83^{\circ}}^{+20}_{-10}$ and ${66^{\circ}}^{+22}_{-18}$. These angles are reduced by about 12% to $θ_{nn} = {78^{\circ}}^{+13}_{-18}$ and ${58^{\circ}}^{+10}_{-14}$ if the laser spectroscopy values of the rms charge radii are used to obtain the rms distance between the cores and the center of mass of the two neutrons. The opening angle in the case of $^{11}$Li is more than 20% larger than recently reported by Nakamura \cite{Nak06}. The analysis is extended to $^{14}$Be and the two-proton Borromean nucleus $^{17}% $Ne where complete data is still not available. Using available experimental data and recent theoretical calculations we find, $θ_{nn} = {64^{0}}^{+9}_{-10}$ and $θ_{pp} = 110^{0}$, respectively.

description: We present an updated version catalogue of gamma-ray source candidates, 12Y-MST, selected using the minimum spanning tree (MST) algorithm on the 12-year Fermi-LAT sky (Pass 8) at energies higher than 10 GeV. The high-energy sky at absolute Galactic latitudes above 20 degrees has been investigated using rather restrictive selection criteria, resulting in a total sample of 1664 photon clusters, or candidate sources. Of these, 230 are new detections, that is, candidate sources without any association in other gamma-ray catalogues. A large fraction of them have interesting counterparts, most likely blazars. We describe the main results on the catalogue selection and search of counterparts. We also present an additional sample of 224 candidate sources (12Y-MSTw), which are clusters that we extracted by applying weaker selection criteria: about 57% of them have not been reported in other catalogues.

description: We investigate the role of nonperturbative, bubble-like inhomogeneities on the decay rate of false-vacuum states in two and three-dimensional scalar field theories. The inhomogeneities are induced by setting up large-amplitude oscillations of the field about the false vacuum as, for example, after a rapid quench or in certain models of cosmological inflation. We show that, for a wide range of parameters, the presence of large-amplitude bubble-like inhomogeneities greatly accelerates the decay rate, changing it from the well-known exponential suppression of homogeneous nucleation to a power-law suppression. It is argued that this fast, power-law vacuum decay -- known as resonant nucleation -- is promoted by the presence of long-lived oscillons among the nonperturbative fluctuations about the false vacuum. A phase diagram is obtained distinguishing three possible mechanisms for vacuum decay: homogeneous nucleation, resonant nucleation, and cross-over. Possible applications are briefly discussed.

The research method of the current doctoral dissertation was the systematic review. All 30 books that have been written by the late PanteleimonFostinis have been read and analyzed by the author of the cuurent doctoral dissertation along with a collection of his homilies. Fostinis has focused on the spiritual, christocentric and eschatological character of Orthodox theology. His work has been very inspiring to new pastors and new preachers who dealt with common subjects. LateMetropolitan PanteleimonFostinis also made a great impression in how he fashioned his message in different ways to various groups of listeners, each in their own unique situations (soldiers, politicians, villagers etc.). To do so he has often used simple words and a plain tone so that his message will be easily conveyed to the members of his parish.

description: Lumbar spinal stenosis (LSS) is a pathology of the lumbar spine resulting from narrowing of the spinal canal. It often results from degenerative processes, which explains its frequency in adults over 50 years of age. Clinically, LSS is responsible of radiculalgia and neurogenic intermittent claudication, sometimes called 'pseudoclaudication', which is characteristic of LSS. In severe forms, a cauda equina syndrome may occur. Imaging plays an important role in the diagnosis. Management is primarily medical. Surgery is considered in case of failure of a well conducted medical treatment in order to preserve the nerve roots by a decompression procedure.
description: Le canal lombaire étroit (CLE) est une pathologie du rachis lombaire qui résulte du rétrécissement du canal rachidien lombaire. Le plus souvent, elle est acquise par des phénomènes dégénératifs ce qui définit le canal lombaire rétréci. Plus rarement, le rétrécissement est constitutionnel, on parle donc de canal étroit. Le CLE est fréquent chez les adultes de plus de 50 ans. Cliniquement, il est responsable de lomboradiculalgies et surtout de claudication intermittente neurogène parfois dite ‘pseudo-claudication’ qui en est caractéristique. Dans les formes sévères, il peut se traduire par un syndrome de la queue de cheval. L’imagerie occupe une place importante dans le diagnostic. La prise en charge est d’abord médicale. La chirurgie est envisagée en cas d’échec d’un traitement médical bien conduit, et se fait dans le but de préserver les racines nerveuses par une intervention de décompression.

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Interpretation of behavioural dynamics and distribution of herring requires explicit consideration of spatial and temporal scales since no single mechanism can explain the pattern on all scales. High resolution sonar and echosounders were used as our observation tools. A protocol for the mesa-scale mapping of herring schools is outlined. Two mesoscale patterns of school clustering was observed as indicated by distribution of nearest neighbour distances; one at 0.05-0.2 km revealed by sonar and another at 0.8-2.5 km revealed by echosounder. The cluster ratio (mean nearest neighbour distance: mean of the average inter-school distance) provides a descriptive index linking scales of distribution pattern within and between clusters of schools. In general, schools were found to be tightly clustered, whilst clusters were patchily distributed. Heightened feeding motivation appears to play the most important role in determining behaviour during this life phase. Specifically, it explains the predominance of relatively small schools and their tendency to be found closer together and more clustered than large schools. Differences in distribution and density of food patches or predators account to some degree for the observations (i) schools were found to be distributed according to their size; both small and large schools having nearest neighbours of similar size more often than expected, (ii) splitting and joining of schools was the most frequently recorded behavioural event. A considerable amount of variation in distribution and dynamics can be accounted for by changes in activity associated with diurnal vertical migrations. Some schools did not perform diurnal vertical migrations. We suggest that when profitable, some herring may 'dip in to the fridge' during the day rather than pursue food on such high energy migrations.

description: Astronomers require efficient automated detection and classification pipelines when conducting large-scale surveys of the (optical) sky for variable and transient sources. Such pipelines are fundamentally important, as they permit rapid follow-up and analysis of those detections most likely to be of scientific value. We therefore present a deep learning pipeline based on the convolutional neural network architecture called $\texttt{MeerCRAB}$. It is designed to filter out the so called 'bogus' detections from true astrophysical sources in the transient detection pipeline of the MeerLICHT telescope. Optical candidates are described using a variety of 2D images and numerical features extracted from those images. The relationship between the input images and the target classes is unclear, since the ground truth is poorly defined and often the subject of debate. This makes it difficult to determine which source of information should be used to train a classification algorithm. We therefore used two methods for labelling our data (i) thresholding and (ii) latent class model approaches. We deployed variants of $\texttt{MeerCRAB}$ that employed different network architectures trained using different combinations of input images and training set choices, based on classification labels provided by volunteers. The deepest network worked best with an accuracy of 99.5$\%$ and Matthews correlation coefficient (MCC) value of 0.989. The best model was integrated to the MeerLICHT transient vetting pipeline, enabling the accurate and efficient classification of detected transients that allows researchers to select the most promising candidates for their research goals.

description: Advancing the utility of social media data for research applications requires methods for automatically detecting demographic information about social media study populations, including users' age. The objective of this study was to develop and evaluate a method that automatically identifies the exact age of users based on self-reports in their tweets. Our end-to-end automatic natural language processing (NLP) pipeline, ReportAGE, includes query patterns to retrieve tweets that potentially mention an age, a classifier to distinguish retrieved tweets that self-report the user's exact age ("age" tweets) and those that do not ("no age" tweets), and rule-based extraction to identify the age. To develop and evaluate ReportAGE, we manually annotated 11,000 tweets that matched the query patterns. Based on 1000 tweets that were annotated by all five annotators, inter-annotator agreement (Fleiss' kappa) was 0.80 for distinguishing "age" and "no age" tweets, and 0.95 for identifying the exact age among the "age" tweets on which the annotators agreed. A deep neural network classifier, based on a RoBERTa-Large pretrained model, achieved the highest F1-score of 0.914 (precision = 0.905, recall = 0.942) for the "age" class. When the age extraction was evaluated using the classifier's predictions, it achieved an F1-score of 0.855 (precision = 0.805, recall = 0.914) for the "age" class. When it was evaluated directly on the held-out test set, it achieved an F1-score of 0.931 (precision = 0.873, recall = 0.998) for the "age" class. We deployed ReportAGE on more than 1.2 billion tweets posted by 245,927 users, and predicted ages for 132,637 (54%) of them. Scaling the detection of exact age to this large number of users can advance the utility of social media data for research applications that do not align with the predefined age groupings of extant binary or multi-class classification approaches.
