description: Deep neural networks (DNNs) have achieved outstanding performance in a wide range of applications, e.g., image classification, natural language processing, etc. Despite the good performance, the huge number of parameters in DNNs brings challenges to efficient training of DNNs and also their deployment in low-end devices with limited computing resources. In this paper, we explore the correlations in the weight matrices, and approximate the weight matrices with the low-rank block-term tensors. We name the new corresponding structure as block-term tensor layers (BT-layers), which can be easily adapted to neural network models, such as CNNs and RNNs. In particular, the inputs and the outputs in BT-layers are reshaped into low-dimensional high-order tensors with a similar or improved representation power. Sufficient experiments have demonstrated that BT-layers in CNNs and RNNs can achieve a very large compression ratio on the number of parameters while preserving or improving the representation power of the original DNNs.

description: Divergence stability of mixed hp-FEM for incompressible fluid flow for a general class of possibly highly irregular meshes is shown. The meshes may be refined anisotropically and contain hanging nodes on geometric patches. The inf-sup constant is independent of the aspect ratio of the elements and the dependence on the polynomial degree is given explicitly. Numerical estimates of inf-sup constants confirm our results.
Navigating from harbored to heavy seas : a history of Japan’s international fisheries in the North Pacific, 1900-1976
Creators: name: Smith, Roger Dale
Publisher: name: University of British Columbia
Year: 2009

description: This paper examines the development of Japanese high-seas fishing with a focus on the North Pacific region. As Japanese fishers expanded activities outside of coastal waters and into international oceans, fisheries became an important issue of foreign policy. Japan had to manage its fisheries activities within a changing international legal framework, analyzed in this paper through regime theory. High-seas fishing in the North Pacific passed through three resource-regime phases, each consecutively more restrictive in correlation with increasing concern over resource depletion. The paper also examines the roles played by American cold war security concerns, changing technology, and environmental concerns to explain how and why fisheries regimes transformed.

description: A supersymmetric one-dimensional matrix procedure similar to relationships of the same type between Dirac and Schrodinger equations in particle physics is described at the general level. By this means we are able to introduce a nonhermitic Hamiltonian having the imaginary part proportional to the solution of a Riccati equation of the Witten type. The procedure is applied to the exactly solvable Morse potential introducing in this way the corresponding nonhermitic Morse problem. A possible application is to molecular diffraction in evanescent waves over nanostructured surfaces

description: AGRICORE is a research project funded by the European Commission under the RUR-04-2018 call, part of the H2020 programme, which proposes an innovative way to apply agent-based modelling to improve the capacity of policymakers to evaluate the impact of agricultural-related measurements under and outside the framework of the Common Agricultural Policy (CAP).This deliverable presents the results of Task 5.3 - Market Module, led by AKD. The objective of Task 5.3 is to design a module which considers the interaction between agents regarding external markets different than Land Market, which is specifically addressed in D5.2. These markets are the production market, on which the price of the outputs of the agricultural holdings is set, but also the markets for other production factors, such as the labour market.The agents, i.e., the agricultural holdings being simulated, interact within the aforementioned markets, so that their aggregated taken actions have an effect on the output of the market themselves.

description: We assess the occurrence of fast neutrino flavor instabilities in two three-dimensional state-of-the-art core-collapse supernova simulations performed using a two-moment three-species neutrino transport scheme: one with an exploding 9$\mathrm{M_{\odot}}$ and one with a non-exploding 20$\mathrm{M_{\odot}}$ model. Apart from confirming the presence of fast instabilities occurring within the neutrino decoupling and the supernova pre-shock regions, we detect flavor instabilities in the post-shock region for the exploding model. These instabilities are likely to be scattering-induced. In addition, the failure in achieving a successful explosion in the heavier supernova model seems to seriously hinder the occurrence of fast instabilities in the post-shock region. This is a consequence of the large matter densities behind the stalled or retreating shock, which implies high neutrino scattering rates and thus more isotropic distributions of neutrinos and antineutrinos. Our findings suggest that the supernova model properties and the fate of the explosion can remarkably affect the occurrence of fast instabilities. Hence, a larger set of realistic hydrodynamical simulations of the stellar collapse is needed in order to make reliable predictions on the flavor conversion physics.

description: Nonholonomic control is a candidate to control nonlinear systems with path-dependant states. We investigate an underactuated flying micro-aerial-vehicle, the ionocraft, that requires nonholonomic control in the yaw-direction for complete attitude control. Deploying an analytical control law involves substantial engineering design and is sensitive to inaccuracy in the system model. With specific assumptions on assembly and system dynamics, we derive a Lie bracket for yaw control of the ionocraft. As a comparison to the significant engineering effort required for an analytic control law, we implement a data-driven model-based reinforcement learning yaw controller in a simulated flight task. We demonstrate that a simple model-based reinforcement learning framework can match the derived Lie bracket control (in yaw rate and chosen actions) in a few minutes of flight data, without a pre-defined dynamics function. This paper shows that learning-based approaches are useful as a tool for synthesis of nonlinear control laws previously only addressable through expert-based design.

description: In many network applications nodes are stable provided they have at least k neighbors, and a network of k-stable nodes is called a k-core. The vulnerability to random attack is characterized by the size of culling avalanches which occur after a randomly chosen k-core node is removed. Simulations of lattices in two, three and four dimensions, as well as small world networks, indicate that power-law avalanches occur in first order k-core systems, while truncated avalanches are characteristic of second order cases.

description: The astrophysical origin of gravitational wave (GW) transients is a timely open question in the wake of discoveries by LIGO/Virgo. In active galactic nuclei (AGNs), binaries form and evolve efficiently by interaction with a dense population of stars and the gaseous AGN disk. Previous studies have shown that stellar-mass black hole (BH) mergers in such environments can explain the merger rate and the number of suspected hierarchical mergers observed by LIGO/Virgo. The binary eccentricity distribution can provide further information to distinguish between astrophysical models. Here we derive the eccentricity distribution of BH mergers in AGN disks. We find that eccentricity is mainly due to binary-single (BS) interactions, which lead to most BH mergers in AGN disks having a significant eccentricity at $0.01\,\mathrm{Hz}$, detectable by LISA. If BS interactions occur in isotropic-3D directions, then $8$--$30\%$ of the mergers in AGN disks will have eccentricities at $10\,\mathrm{Hz}$ above $e_{10\,\rm Hz}\gtrsim 0.03$, detectable by LIGO/Virgo/KAGRA, while $5$--$17\%$ of mergers have $e_{10\,\rm Hz}\geq 0.3$. On the other hand, if BS interactions are confined to the AGN-disk plane due to torques from the disk, with 1-20 intermediate binary states during each interaction, or if BHs can migrate to $\lesssim10^{-3}\,\mathrm{pc}$ from the central supermassive black hole, then $10$--$70\%$ of the mergers will be highly eccentric ($e_{10\,\rm Hz} \geq 0.3$), consistent with the possible high eccentricity in GW190521.

description: We present anisotropic, zero applied magnetic field, temperature dependent resistivity measurements on hexagonal, non-magnetic, YPtIn and LuAgGe single crystals. For these materials the in-plane resistivity, $ρ_{ab}$, is significantly higher than the $c$ - axis one, $ρ_c$, with $ρ_{ab}/ρ_c \approx 1.4$ for YPtIn and $\approx 4.2 - 4.7$ for LuAgGe. The connection between the electronic structure and the anisotropic transport properties is discussed using density functional calculations that link the observed anisotropy with a specific shape of Fermi surface and anisotropy of the Fermi velocities.

Thus, it seems that the method of Yuanxi and Jiashi in general is not restricted to constructing 1-solitary wave solutions of nonlinear wave and evolution equations (NLWEEs).

description: By an extension of Harnad's and Dubrovin's `duality' constructions, the general isomonodromy problem studied by Jimbo, Miwa, and Ueno is equivalent to one in which the linear system of differential equations has a regular singularity at the origin and an irregular singularity at infinity (both resonant). The paper looks at this dual formulation of the problem from two points of view: the symplectic geometry of spaces associated with the loop group of the general linear group, and a generalization of the self-dual Yang-Mills equations.

description: We propose a method for the approximation of high- or even infinite-dimensional feature vectors, which play an important role in supervised learning. The goal is to reduce the size of the training data, resulting in lower storage consumption and computational complexity. Furthermore, the method can be regarded as a regularization technique, which improves the generalizability of learned target functions. We demonstrate significant improvements in comparison to the computation of data-driven predictions involving the full training data set. The method is applied to classification and regression problems from different application areas such as image recognition, system identification, and oceanographic time series analysis.

description: In this thesis, a versatile, multi-threaded C++ template library for total variation (TV) minimization of manifold-valued image data is introduced. The library implements two minimizers: the iteratively reweighted least squares (IRLS) algorithm using the Riemannian Newton method for the optimization step and the proximal point algorithm. Pixels can take values in Euclidean space, on the Sphere, the special orthogonal group, the set of positive definite matrices and the Grassmann manifold while images can be either two- or three-dimensional. Some semi-analytic expressions for the derivatives of the squared distance functions using Kronecker products and a short overview about the relevant Grassmann manifold theory is provided along with a high level documentation of the library and its design concepts. The last part demonstrates the library’s capabilities on different applications in image and video processing, medical imaging and  computer vision. Performance is measured and compared for the IRLS and the proximal point implementations. Lastly the influence of the noisy original data on the the minimizer is investigated.

description: Physics-Informed Neural Networks (PINNs) have recently emerged as a promising approach for solving Partial Differential Equations (PDEs), offering a meshfree alternative that integrates physical principles into the learning process. This presents a new paradigm compared to traditional discretization methods and purely data-driven machine learning techniques. While promising, PINNs are not a panacea; they inherit challenges such as spectral bias and unsta- ble convergence. Moreover, their potential in seismology remains largely unexplored. In this work, we provide a robust and critical assessment of PINNs for solving the elastic wave equation in seismology. We investigate the performance of PINNs on problems with varying degrees of complexity across various seismic sources and parameter models, from constant to highly heterogeneous settings. A pivotal aspect of our work involves investigating whether embedding physical principles directly into the network architecture enhances convergence and accuracy. We test an extensive range of neural architecture designs, from unrestricted, uninformed PINNs to highly specialized ones. We find that integrating an understanding of wave physics into the network design significantly improves accuracy. For instance, introducing a custom wavelet or plane wave layer, coupled with encoder and decoder layers, consistently yields a relative L2 error approximately half that of the standard PINN, as evidenced across numerous experiments. We further demonstrate that this novel architecture enhances accuracy when applied to the acoustic wave equation, underlying the versatility of our network. Another key contribution of our research is the successful conditioning of PINNs on seismic source locations. For seismology applications, this advancement is crucial as it traditionally requires running thousands of seismic simulations to assess various potential source locations. By conditioning PINNs on the source location, the network learns solutions for a class of problems, not just a single setting. Once trained, this method significantly outperforms traditional numerical methods, such as Finite Difference methods, in terms of simulation speed. The capability of conditioned PINNs to infer the wavefield for countless source locations in a single forward pass signifies a considerable advancement towards rapid seismic hazard detection and seismic analysis.

Our findings are supported with numerical simulations of the Susceptible-Infected-Removed (SIR) model on top of real communication networks, where immune nodes are previously identified by a covering algorithm. The results provide useful hints in the way to design and deploying a digital immune system.

description: The dynamics of a many-body system can take many forms, from a purely reversible evolution to fast thermalization. Here we show experimentally and numerically that an assembly of spin 1 atoms all in the same spatial mode allows one to explore this wide variety of behaviors. When the system can be described by a Bogoliubov analysis, the relevant energy spectrum is linear and leads to undamped oscillations of many-body observables. Outside this regime, the non-linearity of the spectrum leads to irreversibity, characterized by a universal behavior. When the integrability of the Hamiltonian is broken, a chaotic dynamics emerges and leads to thermalization, in agreement with the Eigenstate Thermalization Hypothesis paradigm.

description: The composite rotation approach has been used to develop a range of robust quantum logic gates, including single qubit gates and two qubit gates, which are resistant to systematic errors in their implementation. Single qubit gates based on the BB1 family of composite rotations have been experimentally demonstrated in a variety of systems, but little study has been made of their application in extended computations, and there has been no experimental study of the corresponding robust two qubit gates to date. Here we describe an application of robust gates to Nuclear Magnetic Resonance (NMR) studies of approximate quantum counting. We find that the BB1 family of robust gates is indeed useful, but that the related NB1, PB1, B4 and P4 families of tailored logic gates are less useful than initially expected.

The AGRICORE suite stands out for being highly modular and customisable. Thanks to its open-source nature AGRICORE can be applied to a multitude of use cases and easily upgraded as future needs arise.The modules in charge of assessing the impact of the simulated synthetic population in the frame of an agricultural policy are the impact assessment modules (IAMs) and one of them is presented in this deliverable: the environmental and climate IAM. The purpose of this module is to measure the impact of agriculture on the environment and climate and vice-versa and the select KPIs to measure this impact are described in this deliverable. First, the methodology on which the selection of KPIs is based is explained, followed by the 54 KPIs finally selected for the project use cases. These have been characterised and grouped into 6 sections according to the aspect of environment and climate that they measure.Finally, the software implementation, which has an API and a calculation module, is explained. The former is implemented with the third version of the Protocol Buffers language specification, and it communicates the IAM with the other modules, feeds data for the KPI calculations and returns the values of the KPIs after the computation of the data. The calculation module is developed in Python and is dockerised to avoid possible incompatibilities. The full software implementation has been only developed and tested for two KPIs.

To install files of the Borland C ++ Builder programming system, we recommend using a package consisting of two disk images. The package files are a freely redistributable version of the licensed package for installation. Those. files are installed with a binding to a specific computer. This fact must be remembered, for example, in the event of a forced interruption of the package installation due to a failure. In such a situation, the computer is completely cleared not only of the Borland folder, but also of all other installation files. This task may require the use of not quite standard methods of deleting files. Otherwise, a subsequent successful installation attempt will result in only a trial version of the package with a limited validity period. The final step of the installation is a test run of the main program and the recommended procedures are followed carefully.

description: We perform numerical simulations of solid particle motion in a shearing box model of a protoplanetary disc. The accretion flow is turbulent due to the action of the magnetorotational instability. Aerodynamic drag on the particles is modelled using the Epstein law with the gas velocity interpolated to the particle position. The effect of the magnetohydrodynamic turbulence on particle velocity dispersions is quantified for solids of different stopping times t_s, or equivalently, different sizes. The anisotropy of the turbulence is reflected upon the dispersions of the particle velocity components, with the radial component larger than both the azimuthal and vertical components for particles larger than ~ 10 cm (assuming minimum-mass solar nebula conditions at 5 AU). The dispersion of the particle velocity magnitude, as well as that of the radial and azimuthal components, as functions of stopping time, agree with previous analytical results for isotropic turbulence. The relative speed between pairs of particles with the same value of t_s decays faster with decreasing separation than in the case of solids with different stopping time. Correlations in the particle number density introduce a non-uniform spatial distribution of solids in the 10 to 100 cm size range. Any clump of particles is disrupted by the turbulence in less than one tenth on an orbital period, and the maximally concentrated clumps are stable against self-gravitational collapse.

description: We consider magnetic monopoles and strings that appear in non-supersymmetric $SO(10)$ and $E_6$ grand unified models paying attention to gauge coupling unification and proton decay in a variety of symmetry breaking schemes. The dimensionless string tension parameter $Gμ$ spans the range $10^{-6}-10^{-30}$, where $G$ is Newton's constant and $μ$ is the string tension. We show how intermediate scale monopoles with mass $\sim 10^{13}-10^{14}$ GeV and flux $\lesssim 2.8\times 10^{-16}$ ${\mathrm{cm}^{-2}\mathrm{s}^{-1}\mathrm{sr}^{-1}}$, and cosmic strings with $Gμ\sim 10^{-11}-10^{-10}$ survive inflation and are present in the universe at an observable level. We estimate the gravity wave spectrum emitted from cosmic strings taking into account inflation driven by a Coleman-Weinberg potential. The tensor-to-scalar ratio $r$ lies between $0.06$ and $0.003$ depending on the details of the inflationary scenario.

Cosmic-Ray Diffusion Suppression in Star-forming Regions Inhibits Clump Formation in Gas-rich Galaxies

description: Observations of the $γ$-ray emission around star clusters, isolated supernova remnants, and pulsar wind nebulae indicate that the cosmic-ray (CR) diffusion coefficient near acceleration sites can be suppressed by a large factor compared to the Galaxy average. We explore the effects of such local suppression of CR diffusion on galaxy evolution using simulations of isolated disk galaxies with regular and high gas fractions. Our results show that while CR propagation with constant diffusivity can make gaseous disks more stable by increasing the midplane pressure, large-scale CR pressure gradients cannot prevent local fragmentation when the disk is unstable. In contrast, when CR diffusivity is suppressed in star-forming regions, the accumulation of CRs in these regions results in strong local pressure gradients that prevent the formation of massive gaseous clumps. As a result, the distribution of dense gas and star formation changes qualitatively: a globally unstable gaseous disk does not violently fragment into massive star-forming clumps but maintains a regular grand-design spiral structure. This effect regulates star formation and disk structure and is qualitatively different from and complementary to the global role of CRs in vertical hydrostatic support of the gaseous disk and in driving galactic winds.

Fermion masses and mixings in a $U(1)_X$ model based on the $Σ(18)$ discrete symmetry

description: We have built a renormalizable $U(1)_X$ model with a $Σ(18)\times Z_4$ symmetry, whose spontaneous breaking yields the observed SM fermion masses and fermionic mixing parameters. The tiny masses of the light active neutrinos are produced by the type I seesaw mechanism mediated by very heavy right handed Majorana neutrinos. To the best of our knowledge, this model is the first implementation of the $Σ(18)$ flavor symmetry in a renormalizable $U(1)_X$ model. Our model allows a successful fit for the SM fermion masses, fermionic mixing angles and CP phases for both quark and lepton sectors. The obtained values for the physical observables of both quark and lepton sectors are in accordance with the experimental data. We obtain an effective neutrino mass parameter of $\langle m_{ee}\rangle=1.51\times 10^{-3}\, \mathrm{eV}$ for normal ordering and $\langle m_{ee}\rangle =4.88\times 10^{-2} \, \mathrm{eV}$ for inverted ordering which are well consistent with the recent experimental limits on neutrinoless double beta decay.

Setting attentional priorities : a comparison of the contributions of new objects and luminance changes
Creators: name: Austen, Erin Leigh
Publisher: name: University of British Columbia
Year: 2009

description: New objects capture attention more reliably than sudden changes in features of existing objects. Item visibility may be responsible. In the present study, visibility of new objects and luminance changes was controlled by luminance contrast manipulations. In Experiment 1, search for new targets was faster than old targets, at all contrasts. This benefit for new targets was indexed by a search efficiency measure that served as a standard to evaluate other feature changes. In Experiment 2, the attentional effect of luminance changes in old items was measured. Luminance changes generally resulted in small search benefits, although polarity reversals led to larger benefits than changes in magnitude or contrast. Only a simultaneous polarity and contrast change captured attention as efficiently as a new object. It is suggested that new objects are assigned attentional priority; and old objects are treated as new when they undergo changes typically reserved for signaling new objects.

Subjects: AGRICORE H2020

description: AGRICORE is a research project funded by the European Commission under the RUR-04-2018 call, part of the H2020 programme, which proposes an innovative way to apply agent-based modelling to improve the capacity of policymakers to evaluate the impact of agricultural-related measurements under and outside the framework of the Common Agricultural Policy (CAP). The AGRICORE suite stands out for being highly modular and customisable. Thanks to its open-source nature AGRICORE can be applied to a multitude of use cases and easily upgraded as future needs arise.The assessment of agricultural policy impact is made through a set of impact assessment modules (IAMs) based on the outputs of the simulation of a synthetic population of agents which replicates the characteristics, distribution, and interactions of the real population of interest. One of these modules is the delivery of ecosystem services IAM, which is presented in this deliverable. The purpose is to develop an IAM capable of measuring indicators belonging to different fields (i.e. nature, economics, agriculture, etc.) and to derive from them the assessment of the provisioned ecosystem services. For this reason, biophysical measures are included to monitor changes in ecological conditions of the environment, as well as economic and social measures to quantify the impact of eco-services on human welfare.Firstly, an analysis of the previous use case studies related to the modelling and assessment of eco-services is carried out in order to understand already existing methodologies and how they can be extrapolated to other use cases. Sections 2 and 3 present a proposal to model and measure eco-services in the Polish use case of the AGRICORE project, based on the available data, demonstrating that it is possible to shape categories of types of eco-services (supplying, regulating and sustaining, and cultural) through indicators under the CAP. These indicators are composed of quantitative and qualitative measurements.Finally, for modelling eco-services, two existing tools are presented. On the one side, the Ecosystem Services Models Library allows estimating the production of ecosystem goods and services through the interaction of several eco-service modules. On the other side, InVest tool assists in managing natural resources by predicting how changes in ecosystems can alter benefits to human welfare, supporting the decision-making process. Moreover, some of InVest's models of interest are described in detail.

description: The main purposes of the study were to clarify the conceptual reference of environmental awareness and to investigate the relationship between some individual, socio-economic factors and awareness to environmental issues. In addition, the factors that affect the environmental awareness were also determined. Face to face interviews were done with 975 individuals 25 cities were chosen throughout Turkey, which means at least 2 cities from each region. The models were estimated by the ordered logistic regression. Environmental awareness were evaluated from the standpoints of water, air and soil. Among the pollution categories, people were mostly aware of the pollution in air. In policies related to converting sensitivity to environment to action the Turkish government and institutions should take into account gender, education, income, age, industrial city and number of information source.
