    Government-Industry Cooperative Fisheries Research in the North Pacific under the MSFCMA

    Get PDF
    The National Marine Fisheries Serviceā€™s Alaska Fisheries Science Center (AFSC) has a long and successful history of conducting research in cooperation with the fishing industry. Many of the AFSCā€™s annual resource assessment surveys are carried out aboard chartered commercial vessels and the skill and experience of captains and crew are integral to the success of this work. Fishing companies have been contracted to provide vessels and expertise for many different types of research, including testing and evaluation of survey and commercial fishing gear and development of improved methods for estimating commercial catch quantity and composition. AFSC scientists have also participated in a number of industry-initiated research projects including development of selective fishing gears for bycatch reduction and evaluating and improving observer catch composition sampling. In this paper, we describe the legal and regulatory provisions for these types of cooperative work and present examples to illustrate the process and identify the requirements for successful cooperative research

    Anomaly detection in temporal graph data: An iterative tensor decomposition and masking approach

    Get PDF
    Sensors and Internet-of-Things scenarios promise a wealth of interaction data that can be naturally represented by means of timevarying graphs. This brings forth new challenges for the identification and removal of temporal graph anomalies that entail complex correlations of topological features and activity patterns. Here we present an anomaly detection approach for temporal graph data based on an iterative tensor decomposition and masking procedure. We test this approach using highresolution social network data from wearable sensors and show that it successfully detects anomalies due to sensor wearing time protocols.published_or_final_versio

    Non-local corrections to dynamical mean-field theory from the two-particle self-consistent method

    Full text link
    Theoretical methods that are accurate for both short-distance observables and long-wavelength collective modes are still being developed for the Hubbard model. Here, we benchmark against published diagrammatic quantum Monte Carlo results an approach that combines local observables from dynamical mean-field theory (DMFT) with the two-particle self-consistent theory (TPSC). This method (TPSC+DMFT) is relevant for weak to intermediate interaction, satisfies the local Pauli principle and allows us to compute a spin susceptibility that satisfies the Mermin-Wagner theorem. The DMFT double occupancy determines the spin and charge vertices through local spin and charge sum rules. The TPSC self-energy is also improved by replacing its local part with the local DMFT self-energy. With this method, we find improvements for both spin and charge fluctuations and for the self-energy. We also find that the accuracy check developed for TPSC is a good predictor of deviations from benchmarks. TPSC+DMFT can be used in regimes where quantum Monte Carlo is inaccessible. In addition, this method paves the way to multi-band generalizations of TPSC that could be used in advanced electronic structure codes that include DMFT.Comment: 15 pages, 19 figures.

    An ensemble approach to assess hydrological modelsā€™ contribution to uncertainties in the analysis of climate change impact on water resources

    Get PDF
    Over the recent years, several research efforts investigated the impact of climate change on water resources for different regions of the world. The projection of future river flows is affected by different sources of uncertainty in the hydro-climatic modelling chain. One of the aims of the QBic3 5 project (QueĀ“bec-Bavarian International Collaboration on Climate Change) is to assess the contribution to uncertainty of hydrological models by using an ensemble of hydrological models presenting a diversity of structural complexity (i.e. lumped, semi distributed and distributed models). The study investigates two humid, mid-latitude catchments with natural flow conditions; one located in 10 Southern QueĀ“bec (Canada) and one in Southern Bavaria (Germany). Daily flow is simulated with four different hydrological models, forced by outputs from regional climate models driven by a given number of GCMsā€™ members over a reference (1971ā€“2000) and a future (2041ā€“2070) periods. The results show that the choice of the hydrological model does strongly affect the climate change response of selected hydrological indicators, especially those related to low flows. Indicators related to high flows seem less sensitive on the choice of the hydrological model. Therefore, the computationally less demanding models (usually simple, lumped and conceptual) give a significant level of trust for high and overall mean flows

    RepreĢsenter l'Holocauste : le traitement et la repreĢsentation de l'Holocauste dans les museĢes-meĢmoriaux d'AmeĢrique du Nord : eĢtude comparative--le United States Holocaust Memorial Museum et le Centre commeĢmoratif de l'Holocauste aĢ€ MontreĢal

    Get PDF
    Cette recherche a pour objet l'eĢtude de la preĢsentation des meĢmoriaux de l'Holocauste de Washington et de MontreĢal. En plus d'une description sommaire de l'histoire de la perception de l'Holocauste en AmeĢrique du Nord, une contextualisation de l'histoire des deux institutions et une description sommaire des expositions permanentes preĢsenteĢes par celles-ci, une analyse de la preĢsentation est proposeĢe. L'objectif premier est de mettre en relief les partis-pris des gestionnaires des museĢes et des concepteurs d'exposition, en ce qui a trait aĢ€ la diversiteĢ des interpreĢtations possibles de l'Holocauste. SitueĢs aĢ€ cheval entre la meĢmoire et l'histoire sur l'eĢchelle temporelle, les museĢes posent la question de la peĢrenniteĢ et de nombreuses interrogations sont souleveĢes quant aĢ€ la Ā±veĢraciteĢĀ» et la qualiteĢ du reĢcit qu'ils proposent aux visiteurs
