description: A new experimental set-up using a differential pressure transducer was developed, that enables the monitoring of volume changes in cyclic triaxial tests on unsaturated soils. Calibration tests were performed in order to analyze the performance of the set-up, especially in terms of loading frequencies. Based on calibration results, a low frequency of 0.05 Hz was adopted for the tests carried out on the unsaturated loess from northern France. Five water contents were considered in the tests. The obtained results have confirmed the efficiency of the new system for volume change monitoring under cyclic loading. The effect of water content on the cyclic behavior of loess was clearly evidenced. Finally, some suggestions were made to improve the accuracy of the system.

description: Considering a basic enzyme-catalysed reaction, in which the rate of input of the substrate varies periodically in time, we give a necessary and sufficient condition for the existence of a periodic solution of the reaction equations. The proof employs the Leray-Schauder degree, applied to an appropriately constructed homotopy.

description: Herein is a collection of poems each having something to do with how and/or why we figure our bodies in relation to the Space we tend to call the World, History, or Family. The first section, entitled "Settlement," deals primarily with the idea of orienting ourselves in terms of family in its loosest sense. The second section, "Generation," questions the relation of space and family in terms of the Bible's Old Testament. The penultimate section, ''Landscape," considers the body as physical presence in a space which by definition should be alien to it. "The Naming," the final section of the manuscript, considers the body as place (or space) itself.

Empirical open stope design in Canada
Creators: name: Potvin, Yves
Publisher: name: University of British Columbia
Year: 2010

description: This thesis addresses the topic of underground excavation stability in open stope mining methods. There are three fundamental aspects to be considered in an engineering rock mechanics design of open stopes. The first aspect is the characterization of the rock mass to identify and quantify the properties and components affecting the rock mass behaviour. The second aspect is the effect of the stress fields on the rock mass that may result in zones of high compressive stress or zones of relaxation in stope walls. The third aspect is the physical condition of the problem and is defined primarily by the size, geometry and relative orientation of openings with regard to the rock mass and the stress field. The interaction of these three fundamental aspects constitutes the problem to be investigated. The principal objective of the study is to develop a reliable geomechanical model (based on the above three aspects) that can predict the stability of open stopes in typical Canadian geological settings. An empirical approach was chosen for the development of the model, because of the complexity of the problem and the difficulty in estimating the input parameters with precision. Empirical methods are likely to be more reliable since they make use of past experience. A considerable amount of effort has been spent in building a broad data base which includes more than 250 case histories of unsupported and supported stopes from 34 Canadian mines. The application of the model in the back-analysis of a large number of representative case histories allowed calibration of each of the factors composing the model. Since the model's prediction corresponds very well to the actual stope behaviour in most case histories, the model is considered empirically verified. The effect of external factors (parameters affecting stope stability that are not related to the geotechnical or geometrical conditions) have also been investigated. The limit of applicability of cable bolting has been defined and rough guidelines for the design of cable support systems are proposed based on the systematic compilation of past experience. The effect of blasting, although not quantified, has been observed in 18 case histories. More research is required in order to include the effect of blasting in the actual modelwhile the effect of time is not of concern in open stope mining, when there are no mining activities in the imediate area of the investigated stope.

description: The maximal roundness of a metric space is a quantity that arose in the study of embeddings and renormings. In the setting of Banach spaces, it was shown by Enflo that roundness takes on a much simpler form. In this paper we provide simple computations of the roundness of many standard Banach spaces, such as $\ell^{p}$, the Lebesgue-Bochner spaces $\ell^{p}(\ell^{q})$ and the Schatten ideals $S_{p}$. We also introduce a property that is dual to that of roundness, which we call coroundness, and make explicit the relation of these properties to the geometric concepts of smoothness and convexity of Banach spaces. Building off the work of Enflo, we are then able to provide multiple non-trivial equivalent conditions for a Banach space to possess maximal roundness greater than $1$. Using these conditions, we are able to conclude that certain Orlicz spaces possess non-trivial values of roundness and coroundness. Finally, we also use these conditions to provide an explicit example of a $2$-dimensional Banach space whose maximal roundness is not equal to that of its dual.

description: No abstracts are to be cited without prior reference to the author.Cod (Gadus morhua) were sampled from coastal sites off the south and south-east coast of Iceland. In this study, two lmown spawning localities of cod (Loftstaoabraun and Kantur) and three feeding localities (Reykjanesgrunn, Eyrabakkabugur and Austfjaroadjup) were selected. Results from tagging experiments were used to find probable feeding grounds for cod migrating from the two spawning grounds. The samples were analysed for allele variation at the synaptophysin (Syp I) and haemoglobin (HbI) loci. As for the Syp I variation, a global test of Hardy-Weinberg equilibrium, test of allele frequency homogeneity, FsT test, analysis of molecular variance and Nei's genetic distance measures, all revealed significant differences between two groups; Loftstaoahraun (spawning ground), Reykjanesgrunn and Eyrabakkabugur (feeding grounds) on one hand and Kantur (spawning ground) and Austfjaroadjup (feeding ground) on the other hand. In addition to large differences between these two groups, a considerable genetic heterogeneity was detected within the former group. The results indicate that the cod in south and south-east Icelandic waters does not belong to one panmictic population.

description: Deep learning-based algorithms can provide state-of-the-art accuracy for remote sensing technologies such as unmanned aerial vehicles (UAVs)/drones, potentially enhancing their remote sensing capabilities for many emergency response and disaster management applications. In particular, UAVs equipped with camera sensors can operating in remote and difficult to access disaster-stricken areas, analyze the image and alert in the presence of various calamities such as collapsed buildings, flood, or fire in order to faster mitigate their effects on the environment and on human population. However, the integration of deep learning introduces heavy computational requirements, preventing the deployment of such deep neural networks in many scenarios that impose low-latency constraints on inference, in order to make mission-critical decisions in real time. To this end, this article focuses on the efficient aerial image classification from on-board a UAV for emergency response/monitoring applications. Specifically, a dedicated Aerial Image Database for Emergency Response applications is introduced and a comparative analysis of existing approaches is performed. Through this analysis a lightweight convolutional neural network architecture is proposed, referred to as EmergencyNet, based on atrous convolutions to process multiresolution features and capable of running efficiently on low-power embedded platforms achieving upto 20x higher performance compared to existing models with minimal memory requirements with less than 1% accuracy drop compared to state-of-the-art models.

Coal blending model : theory and application of the model
Creators: name: Bauer, Edwin Alois
Publisher: name: University of British Columbia
Year: 2010

description: Over the past decade, most Western Canadian coal mines have been forced to mine deposits containing multiple seams of coal, with varying coal qualities. This change in mining practice has caused considerable challenges for coal washery personnel. Blending or homogenization of these multiple seams has been the standard approach in attempting to minimize the disruption to washery operations. The purpose of this research was to develop a method of quantifying the effects of a controlled blending program on preparation plant yield, thus providing a way to optimize the blending program within the constraints of the mining program, the processing unit operations, and the final product quality constraints. A yield-based objective function called the Coal Blending Coefficient was developed to evaluate the effects of blending on preparation plant yield. This formula can be described as the difference in yield between blending and batching of the same coals. The Coal Blending Coefficient was then incorporated into a collection of existing computer programs called the CANMET Coal Data Manipulation Programs, and after some modifications, the Coal Blending Model was produced. The Coal Plant Simulation program, which is included in the CANMET program, is the heart of the model, while the Coal Blending coefficient values allow the model to rank the blends . To date, approximately twenty runs of the Coal Blending Model have been tried on coals from three British Columbia coal deposits. The results range from zero benefit of blending for similar quality seams, to potential gains of over five percent increase in yield for highly varied seam qualities. Most runs produced Coal Blending Coefficient values in excess of one, which represent a potential gain in profits of over ten million dollars for the Western Canadian coal industry. Though these initial trials have been successful, further improvements must be made to the Coal Blending Model, and actual field testing performed before this model would be available for use within the industry.

description: In co-annihilation scenarios, the weakly interacting dark matter particle (WIMP) is close in mass to another particle that can decay into the WIMP. As a result, both particles freeze out at roughly the same time in the early universe, and both contribute to the effective dark matter annihilation cross-section. Since the heavier particle does not need to be weakly interacting, the co-annihilation processes are in general subject to sizeable radiative corrections. Here this is analyzed for the example of neutralino-stop co-annihilation in supersymmetry. The leading QCD corrections are calculated and it is found that they have a large effect on the effective annihilation cross-section, reaching more than 50% in some regions of parameter space.

description: No abstracts are to be cited without prior reference to the author.Genetic variation within and between 13 anadromous, resident and stocked brown trout populations in Iceland was studied using 50 allozyme loci (25 allozyme systems). A total of 523 samples were screened and seven loci were found to be polymorphic by the 0,95 criterion for polymorphism (AAT-2*, AAT-4*, EST*, G3PDH-2*, LDH-5, MDH-2* and MDH-3*) and two were variable (AAT-1* and mAAT-112*). The average observed heterozygosity (H) varied from 0.027-0.058 in the wild populations where n>20 and the average H was 0.040 (SE=0.011). The average heterozygosity values in the two stocked brown trout was lower than in the wild brown trout, or 0.006 and 0.016 (Kollafjordur and L. Skorradalsvatn, respectively). The contingency chi-square analysis at the allozyme loci between all populations showed significant differences in allele frequencies in all of the comparisons. The Wright's FsT value was 0.380 and the total gene diversity (HT) was 0.368. The UPGMA dendrogram of the relationships oflcelandic brown trout populations b.ased On the Nei' s (1978) genetic distance, showed that the distance was less between populations within the same region than between populations from different regions.

Image Decomposition of Barred Galaxies and AGN Hosts
Creators: name: Gadotti, Dimitri Alexei
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I present the results of multi-component decomposition of V and R broadband images of a sample of 17 nearby galaxies, most of them hosting bars and active galactic nuclei. I use BUDDA v2.1 to produce the fits, allowing to include bars and AGN in the models. A comparison with previous results from the literature shows a fairly good agreement. It is found that the axial ratio of bars, as measured from ellipse fits, can be severely underestimated if the galaxy axisymmetric component is relatively luminous. Thus, reliable bar axial ratios can only be determined by taking into account the contributions of bulge and disc to the light distribution in the galaxy image. Through a number of tests, I show that neglecting bars when modelling barred galaxies can result in a overestimation of the bulge-to-total luminosity ratio of a factor of two. Similar effects result when bright, type 1 AGN are not considered in the models. By artificially redshifting the images, I show that the structural parameters of more distant galaxies can in general be reliably retrieved through image fitting, at least up to the point where the physical spatial resolution is ~ 1.5 Kpc. This exercise shows that disc parameters are particularly robust, but bulge parameters are prone to errors if its effective radius is small compared to the seeing radius, and might suffer from systematic effects. In this low resolution regime, the effects of ignoring bars are still present, but AGN light is smeared out. I briefly discuss the consequences of these results to studies of the structural properties of galaxies, in particular on the stellar mass budget in the local universe. With reasonable assumptions, it is possible to show that the stellar content in bars can be similar to that in classical bulges and elliptical galaxies. (Abridged)

description: In molecular biology, advances in high-throughput technologies have made it possible to study complex multivariate phenotypes and their simultaneous associations with high-dimensional genomic and other omics data, a problem that can be studied with high-dimensional multi-response regression, where the response variables are potentially highly correlated. To this purpose, we recently introduced several multivariate Bayesian variable and covariance selection models, e.g., Bayesian estimation methods for sparse seemingly unrelated regression for variable and covariance selection. Several variable selection priors have been implemented in this context, in particular the hotspot detection prior for latent variable inclusion indicators, which results in sparse variable selection for associations between predictors and multiple phenotypes. We also propose an alternative, which uses a Markov random field (MRF) prior for incorporating prior knowledge about the dependence structure of the inclusion indicators. Inference of Bayesian seemingly unrelated regression (SUR) by Markov chain Monte Carlo methods is made computationally feasible by factorisation of the covariance matrix amongst the response variables. In this paper we present BayesSUR, an R package, which allows the user to easily specify and run a range of different Bayesian SUR models, which have been implemented in C++ for computational efficiency. The R package allows the specification of the models in a modular way, where the user chooses the priors for variable selection and for covariance selection separately. We demonstrate the performance of sparse SUR models with the hotspot prior and spike-and-slab MRF prior on synthetic and real data sets representing eQTL or mQTL studies and in vitro anti-cancer drug screening studies as examples for typical applications.

description: Motivated by experiments on colloidal membranes composed of chiral rod-like viruses, we use Monte Carlo methods to determine the phase diagram for the liquid crystalline order of the rods and the membrane shape. We generalize the Lebwohl-Lasher model for a nematic with a chiral coupling to a curved surface with edge tension and a resistance to bending, and include an energy cost for tilting of the rods relative to the local membrane normal. The membrane is represented by a triangular mesh of hard beads joined by bonds, where each bead is decorated by a director. The beads can move, the bonds can reconnect and the directors can rotate at each Monte Carlo step. When the cost of tilt is small, the membrane tends to be flat, with the rods only twisting near the edge for low chiral coupling, and remaining parallel to the normal in the interior of the membrane. At high chiral coupling, the rods twist everywhere, forming a cholesteric state. When the cost of tilt is large, the emergence of the cholesteric state at high values of the chiral coupling is accompanied by the bending of the membrane into a saddle shape. Increasing the edge tension tends to flatten the membrane. These results illustrate the geometric frustration arising from the inability of a surface normal to have twist.

description: We consider the theory of the non-linear spectroscopy for a single molecule undergoing stochastic dynamics and interacting with a sequence of two laser pulses. General expressions for photon counting statistics are obtained, and an exact solution to the problem of the Kubo-Anderson process is found. In the limit of impulsive pulses the information on the photon statistics is contained in the molecule's dipole correlation function. The selective limit where temporal resolution is maintained, the semi-classical approximation and the fast modulation limit exhibit general behaviors of this new type of spectroscopy. We show how the design of the external field leads to rich insights on dynamics of individual molecules which are different than those found for an ensemble.
Control Architecture of the Double-Cross-Correlation Processor for Sampling-Rate-Offset Estimation in Acoustic Sensor Networks

description: Distributed hardware of acoustic sensor networks bears inconsistency of local sampling frequencies, which is detrimental to signal processing. Fundamentally, sampling rate offset (SRO) nonlinearly relates the discrete-time signals acquired by different sensor nodes. As such, retrieval of SRO from the available signals requires nonlinear estimation, like double-cross-correlation processing (DXCP), and frequently results in biased estimation. SRO compensation by asynchronous sampling rate conversion (ASRC) on the signals then leaves an unacceptable residual. As a remedy to this problem, multi-stage procedures have been devised to diminish the SRO residual with multiple iterations of SRO estimation and ASRC over the entire signal. This paper converts the mechanism of offline multi-stage processing into a continuous feedback-control loop comprising a controlled ASRC unit followed by an online implementation of DXCP-based SRO estimation. To support the design of an optimum internal model control unit for this closed-loop system, the paper deploys an analytical dynamical model of the proposed online DXCP. The resulting control architecture then merely applies a single treatment of each signal frame, while efficiently diminishing SRO bias with time. Evaluations with both speech and Gaussian input demonstrate that the high accuracy of multi-stage processing is maintained at the low complexity of single-stage (open-loop) processing.

Branching Ratios and CP Asymmetries of B \to a_1(1260) πand a_1(1260) K Decays

description: We present the studies of the decays $B\to a_1(1260) π$ and $a_1(1260) K$ within the framework of QCD factorization. Due to the G-parity, unlike the vector meson, the chiral-odd two-parton light-cone distribution amplitudes of the $a_1$ are antisymmetric under the exchange of quark and anti-quark momentum fractions in the SU(2) limit. The branching ratios for $a_1 π$ modes are sensitive to tree--penguin interference. The resultant ${\cal B}(B^0 \to a_1^\pm π^\mp)$ are in good agreement with the data. However, using the current Cabibbo--Kobayashi--Maskawa angles, $β=22.0^\circ$ and $γ=59.0^\circ$, our results for the mixing-induced parameter $S$ and $α_{\rm eff}$ differ from the measurements of the time-dependent CP asymmetries in the decay $B^0\to a_1^\pm π^\mp$ at about the $3.7σ$ level. This puzzle may be resolved by using a larger $γ\gtrsim 80^\circ$. For $a_1 K$ modes, the annihilation topologies give sizable contributions and are sensitive to the first Gegenbauer moment of the leading-twist tensor (chiral-odd) distribution amplitude of the $a_1$ meson. The $B\to a_1 K$ amplitudes resemble the corresponding $B\to πK$ ones very much. Taking the ratios of corresponding CP-averaged $a_1 K$ and $πK$ branching ratios, we can extract information relevant to the electroweak penguins and annihilations. The existence of new-physics in the electroweak penguin sector and final state interactions during decays can thus be explored.

A very brief outline of the theoretical basis for cross-section calculations is followed by more in-depth discussions of Monte Carlo sampling techniques, including the use of the CERN package DIVON. The reader is introduced to the concepts involved in detector simulation; specifically, the CERN package GEANT in presented and discussed in some detail. Finally, methods of modelling external conversion processes are taken up. Illustrations for the discussions are taken from the various rare decay modes of the π⁰. Example code and some sample results comparing simulated and real data are given in the appendices.

description: No abstracts are to be cited without prior reference to the author.Stocking is employed in coastal fisheries management as a last resort in areas where the local fish stock have declined drastically due to either mismanagement, environmental degradation cir a combination of both. A study carried out in Denmark using turbot as a model species showed that there is a potential for enhancement of flatfish through stocking. Turbot was chosen because it is a commercially important species and available from local hatcheries. The rearing techniques were so improved as to provide normally pigmented juveniles which were tagged before being released. In that study the performance of the reared and wild fish were.compared and certain important differences in, for example, feeding behaviour and cryptic. behaviour were .observed, especially in the initial period after release. Some of the behaviours observed in the Danish-reared turbot were different to those observed for fish from for example UK hatcheries, suggesting behavioural effects of remaining system or practices.

description: A large number of pulsars and X-rays sources are detected in globular clusters. To understand the structure and content of these clusters, accurate distances are required. We derive the distances of Terzan 5, Liller 1 and UKS 1 using as a reference a recent distance determination of NGC 6528, based on HST/NICMOS and NTT/SOFI infrared photometry. The distance of the metal-poor cluster Terzan 4 was derived from a comparison with M92 in NICMOS bands. Distances of the metal-rich clusters are obtained by comparison of the Horizontal Branch (HB) level of the clusters, relative to the reddening line passing through the HB of NGC 6528. We use methods based on NICMOS bands and transformations to J and H magnitudes with different assumptions. Liller~1 and Terzan~4 are found to be at the central bulge distance, UKS~1 is beyond the Galactic center, while Terzan 5 is closer to the Sun than the other four clusters. The distance of Terzan 5 is of paramount importance, given the impact of its population of 21 pulsars, which is related to the high cluster density. The distance of Terzan 5 is found to be d$_{\odot}$=5.5$\pm$0.9 kpc from the Sun, thus closer to us than values given in studies of pulsars in Terzan 5. As a consequence, the higher cluster density is even more favourable for formation of the millisecond pulsars recently detected in this cluster.

description: This is the second part and the completion of the updated check-list of spontaneous vascular plants growing in Lazio (Latium), Italy. The first part appeared on this same Journal (voi. 52, suppl. 11, 1994). Plants listed here are the Monocotyledons. They are treated here in the same fashion as in Part one.Comparing the whole list to that published ten years ago (Anzalone, 1984) it results that entities found in Latium now number 3185 (instead of 3040), that only 93 (instead of 127) have not been found again since last century and that 122 (instead of 155) are those which are given doubtfully. The number of entities which can be found in Latium and are not mentioned in Pignatti (1982) has increased to 432 (from 392).

description: Semantic segmentation is an essential part of deep learning. In recent years, with the development of remote sensing big data, semantic segmentation has been increasingly used in remote sensing. Deep convolutional neural networks (DCNNs) face the challenge of feature fusion: very-high-resolution remote sensing image multisource data fusion can increase the network's learnable information, which is conducive to correctly classifying target objects by DCNNs; simultaneously, the fusion of high-level abstract features and low-level spatial features can improve the classification accuracy at the border between target objects. In this paper, we propose a multipath encoder structure to extract features of multipath inputs, a multipath attention-fused block module to fuse multipath features, and a refinement attention-fused block module to fuse high-level abstract features and low-level spatial features. Furthermore, we propose a novel convolutional neural network architecture, named attention-fused network (AFNet). Based on our AFNet, we achieve state-of-the-art performance with an overall accuracy of 91.7% and a mean F1 score of 90.96% on the ISPRS Vaihingen 2D dataset and an overall accuracy of 92.1% and a mean F1 score of 93.44% on the ISPRS Potsdam 2D dataset.

description: This work shows the results of a floristic research on the area of Monteflavio (M. Lucretili, Latium), carried out during the seasons winter 1994-autumn 1995. The entities indicated are 809 distributed in 87 families. Some are interesting for their rarity in Latium, such as Altea setosa (Boiss.) Alef., Seseli tommasinii Reichenb. fil., Melampyrum barbatimi Waldst. et Kit. ex Willd. subsp. carstiense Ronn. and some others; from the analysis of the biological spectrum, it results a prevalence of Therophyta, which is in accordance with the position of the area analysed, followed by Hemicryptophyta. The corological spectrum also shows the prevalence of Eurimediterranean species, followed by Stenomediterranean ones, in conformity with the phyto- climatical features of these central Italy districts

description: We introduce a Reed-Frost epidemic model with recursive contact tracing and asymptomatic transmission. This generalizes the branching-process model introduced by the authors in a previous work [arxiv:2004.07237] to finite populations and general contact networks. We simulate the model numerically for two representative examples, the complete graph and the square lattice. On both networks, we observe clear signatures of a contact-tracing phase transition from an "epidemic phase" to an "immune phase" as contact-network coverage is increased. We verify that away from the singular line of perfect tracing, the finite-size scaling of the contact-tracing phase transition on each network lies in the corresponding percolation universality class. Finally, we use the model to quantify the efficacy of recursive contact-tracing in regimes where epidemic spread is not contained.

Radio Continuum and Star Formation in CO-rich Early Type Galaxies

description: In this paper we present new high resolution VLA 1.4 GHz radio continuum observations of five FIR bright CO-rich early-type galaxies and two dwarf early-type galaxies. The position on the radio-FIR correlation combined with striking agreements in morphology between high resolution CO and radio maps show that the radio continuum is associated with star formation in at least four of the eight galaxies. The average star formation rate for the sample galaxies detected in radio is approximately 2 solar masses per year. There is no evidence of a luminous AGN in any of our sample galaxies. We estimate Toomre Q values and find that the gas disks may well be gravitationally unstable, consistent with the above evidence for star formation activity. The radio continuum emission thus corroborates other recent suggestions that star formation in early type galaxies may not be uncommon.
