description: Every invertible, measure-preserving dynamical system induces a Koopman operator, which is a linear, unitary evolution operator acting on the $L^2$ space of observables associated with the invariant measure. Koopman eigenfunctions represent the quasiperiodic, or non-mixing, component of the dynamics. The extraction of these eigenfunctions and their associated eigenfrequencies from a given time series is a non-trivial problem when the underlying system has a dense point spectrum, or a continuous spectrum behaving similarly to noise. This paper describes methods for identifying Koopman eigenfrequencies and eigenfunctions from a discretely sampled time series generated by such a system with unknown dynamics. Our main result gives necessary and sufficient conditions for a Fourier function, defined on $N$ states sampled along an orbit of the dynamics, to be extensible to a Koopman eigenfunction on the whole state space, lying in a reproducing kernel Hilbert space (RKHS). In particular, we show that such an extension exists if and only if the RKHS norm of the Fourier function does not diverge as $ N \to \infty $, in which case the corresponding Fourier frequency is also a Koopman eigenfrequency. If such an RKHS extension does not exist, we can still construct an $L^2$ approximation of the eigenfunction. Numerical experiments on mixed-spectrum systems with weak periodic components demonstrate that this approach has significantly higher skill in identifying Koopman eigenfrequencies compared to conventional spectral estimation techniques based on the discrete Fourier transform.

description: No abstracts are to be cited without prior reference to the author.The presence of two different cod stocks (fig 1) in the Baltic Sea is an accepted concept and is reflected in the separate management of the stocks. However, great difficulties in allocation of the catches arise from the unknown extent of stock mixture. As the spawning seasons for both stocks differ by several months, the mixture can be a problem in stock assessment and TAC allocation. Stock identification of Baltic cod was attemp-ted by tagging experiments, morpho-metry, genetics or bloodtype determina-tion as well as discrimination of spawning areas and conditions. With these meth-ods it is not possible, to assign individuals to a particular stock..

description: We consider novel unusual effects in superconductor-ferromagnet (S/F) structures. In particular we analyze the triplet component (TC) of the condensate generated in those systems.This component is odd in frequency and even in the momentum, which makes it insensitive to non-magnetic impurities. If the exchange field is not homogeneous in the system the triplet component is not destroyed even by a strong exchange field and can penetrate the ferromagnet over long distances. Some other effects considered here and caused by the proximity effect are: enhancement of the Josephson current due to the presence of the ferromagnet, induction of a magnetic moment in superconductors resulting in a screening of the magnetic moment, formation of periodic magnetic structures due to the influence of the superconductor, etc. We compare the theoretical predictions with existing experiments.

description: A model of parton multiple scattering in a dense and expanding medium is described. The simulated results reproduce the general features of the data. In particular, in the intermediate trigger momentum region there is a dip-bump structure, while at higher trigger momentum the double bumps merge into a central peak. Also, a new measure is proposed to quantify the azimuthal distribution with the virtue that it suppresses the statistical fluctuations event-by-event, while enhancing the even-structure of the signal.

description: We perform a protocol for multipartite quantum clock synchronization under the influence of Unruh thermal noise. The clocks consisting of Unruh-DeWitt detectors when one of detectors accelerated is obtained. To estimate the time difference between the clocks, we calculate the time probability and analyze how the probability is influenced by the Unruh thermal noise and other factors. It is shown that both relativistic motion and interaction between the atom and the external scalar field affect the choice of optimal number of excited atoms in the initial state, which leads to a higher clock adjustment accuracy. Time probabilities for different types of initial states approach to the same value in the limit of infinite acceleration, while tend to different minimums with increasing number of atoms. In addition, the accuracy of clock synchronization using a pair of entangled clocks in two-party system is always higher than in an multipartite system, while the optimal $Z$-type multipartite initial state always perform better than the $W$-type state.

description: We present the first measurements of the X-ray size-temperature (ST) relation in intermediate redshift (z~0.30) galaxy clusters. We interpret the local ST relation (z~0.06) in terms of underlying scaling relations in the cluster dark matter properties, and then we use standard models for the redshift evolution of those dark matter properties to show that the ST relation does not evolve with redshift. We then use ROSAT HRI observations of 11 clusters to examine the intermediate redshift ST relation; for currently favored cosmological parameters, the intermediate redshift ST relation is consistent with that of local clusters. Finally, we use the ST relation and our evolution model to measure angular diameter distances; with these 11 distances we evaluate constraints on Omega_M and Omega_L which are consistent with those derived from studies of Type Ia supernovae. The data rule out a model with Omega_M=1 and Omega_L=0 with 2.5 sigma confidence. When limited to models where Omega_M+Omega_L=1, these data are inconsistent with Omega_M=1 with 3 sigma confidence.

In both compounds a finite negative spin and positive orbital magnetic moment was detected. The experimental results are in good agreement with band-structure calculations for (Sr/Ca)2CrWO6 using the full-potential linear muffin-tin orbital method. It is remarkable, that the magnetic ordering temperature, TC, is correlated with the magnetic moment at the 'non-magnetic' W atom.

description: We examine noncommutative Yang-Mills and open string theories using magnetically and electrically deformed supergravity duals. The duals are near horizon regions of Dp-brane bound state solutions which are obtained by using O(p+1,p+1) transformations of Dp-branes. The action of the T-duality group implies that the noncommutativity parameter is constant along holographic RG-flows. The moduli of the noncommutative theory, i.e., the open string metric and coupling constant, as well as the zero-force condition are shown to be invariant under the O(p+1,p+1) transformation, i.e., deformation independent. We find sufficient conditions, including zero force and constant dilaton in the ISO(3,1)-invariant D3 brane solution, for exact S-duality between noncommutative Yang-Mills and open string theories. These results are used to construct noncommutative field and string theories with N=1 supersymmetry from the T^(1,1) and Pilch-Warner solutions. The latter has a non-trivial zero-force condition due to the warping.

Shear enhancement in RC beams loaded on the tension face
Creators: name: Elwakeel, Abobakr
Publisher: name: Imperial College London
Year: 2019

description: Shear strength of reinforced concrete beams significantly enhances when loads are applied closer to the support due to the arching action. This enhancement is widely investigated and has been included in the design codes. However, scarce resources are available in the literature regarding this enhancement for the case of multiple point loads applied within the enhancement zone; in addition, the available literature focuses on loads applied to the flexural compression face. Situations where multiple point loads are applied on the tension face are found in practice in structures like balanced-cantilever crosshead girders of bridges and transfer girders near the supports. Nevertheless, research considering this configuration has not been found in the available literature. The aim of this research is to study the effect of the loading arrangements on the shear strength enhancement of deep beams loaded on the compression or tension face with multiple point loads. This research was motivated by differences in the principal compressive stress trajectories obtained with nonlinear finite element analysis for the two different configurations. The author conducted an experimental program to investigate the influence of loading face, the effect of varying the ratio between loads applied within the enhancement zone and the influence on shear enhancement of partly loading the beam outside the enhancement zone. Detailed measurements of the crack kinematics and global deformation were obtained during the tests using the digital images correlation system. These measurements were used to provide descriptive models of the deformed beams and to evaluate the shear transfer actions of the tested beams. Strength of the tested beams was estimated using design codes (BS8110, EC2 2004 and MC2010) and non-linear finite element analysis. A novel practical strut-and-tie model was developed for the case of multiple point load applied to the tension face of the beams. This model correctly predicted the failure plane, fairly represented the stress field, and it is suitable for multiple loads applied entirely inside or partly outside the shear enhancement zone.

description: Significant scientific and technological progress in the field of spintronics is based on trilayer magnetic tunnel junction devices which principally rely on the physics of single barrier tunneling. While technologically relevant devices have been prototyped, the physics of single barrier tunneling poses ultimate limitations on the performance of magnetic tunnel junction devices. Here, we propose a fresh route toward high performance magnetic tunnel junctions by making electronic analogs of optical phenomena such as anti-reflections and Fabry-Pèrot resonances. The devices we propose feature anti-reflection enabled superlattice heterostructures sandwiched between the fixed and the free ferromagnets of the magnetic tunnel junction structure. Our predictions are based on the non-equilibrium Green's function spin transport formalism coupled self-consistently with the Landau-Lifshitz-Gilbert-Slonczewski equation. Owing to the physics of bandpass spin filtering in the bandpass superlattice magnetic tunnel junction device, we demonstrate an ultra-high boost in the tunnel magneto-resistance (TMR$\approx5\times10^4\%$) and nearly 92% suppression of spin transfer torque switching bias in comparison to a traditional trilayer magnetic tunnel junction device. We rationalize improvised spin transfer torque switching via analysis of the Slonczewski spin current transmission spectra. The proof of concepts presented here can lead to next-generation spintronics device design harvesting the rich physics of superlattice heterostructures and exploiting spintronic analogs of optical phenomena.

description: The chiral phase transition is studied in an extended Nambu--Jona-Lasinio model with eight-quark interactions. Equations for scalar and vector quark densities, derived in the mean field approximation, are nonlinear and mutually coupled. The scalar-type nonlinear term hastens the restoration of chiral symmetry, while the scalar-vector mixing term makes the transition sharper. The scalar-type nonlinear term shifts the critical endpoint toward the values predicted by lattice QCD simulations and the QCD-like theory.

description: No abstracts are to be cited without prior reference to the author.The inherent conflicts between objectives in fisheries management (e.g. MSY vs. conservation interests) are a hurdle for managers and scientists. However, some objectives may be compatible (e.g. economic yield and ecosystem preservation, Hilborn 2007) and could promote stakeholder consensus. The purpose of this study is to explore the “zone of new consensus” as outline by Hilborn (2007) and to develop a formal and quantitative approach to defining fisheries management objectives through stakeholder-specific utility functions. First, multiple objectives are reflected in a clearly defined utility function for each stakeholder group. Second, simulations are run to find the resulting stakeholder groups’ utility. The preliminary results illustrate a formal route towards deriving appropriate management regimes with focus on compatible management goals to promote a new paradigm of stakeholder consensus, incentives, and success in fishery management.

description: The phases of A$_2$Mn$_8$O$_{16}$ hollandite group oxides emerge from the competition between ionic interactions, Jahn-Teller effects, charge ordering, and magnetic interactions. Their balanced treatment with feasible computational approaches can be challenging for commonly used approximations in Density Functional Theory. Three examples (A = Ag, Li and K) are studied with a sequence of different approximate exchange-correlation functionals. Starting from a generalized gradient approximation (GGA), an extension to include van der Waals interactions and a recently proposed meta-GGA are considered. Then local Coulomb interactions for the Mn $3d$ electrons are more explicitly considered with the DFT+$U$ approach. Finally selected results from a hybrid functional approach provide a reference. Results for the binding energy of the A species in the parent oxide highlight the role of van der Waals interactions. Relatively accurate results for insertion energies can be achieved with a low $U$ and a high $U$ approach. In the low $U$ case, the materials are described as band metals with a high symmetry, tetragonal crystal structure. In the high $U$ case, the electrons donated by A result in formation of local Mn$^{3+}$ centers and corresponding Jahn-Teller distortions characterized by a local order parameter. The resulting degree of monoclinic distortion depends on charge ordering and magnetic interactions in the phase formed. The reference hybrid functional results show charge localization and ordering. Comparison to low temperature experiments of related compounds suggests that charge localization is the physically correct result for the hollandite group oxides studied here. . . .

description: We present PLANET observations of OGLE-1999-BUL-23, a binary-lens microlensing event towards the Galactic bulge. PLANET observations in the I and V bands cover the event from just before the first caustic crossing until the end of the event. In particular, a densely-sampled second caustic crossing enables us to derive the linear limb-darkening coefficients of the source star; c_V = 0.786^{+0.080}_{-0.078} and c_I = 0.632^{+0.047}_{-0.037}. Combined analysis of the light curve and the color-magnitude diagram suggests that the source star is a G/K subgiant in the Galactic bulge (T_eff = 4800 K). The resulting linear limb-darkening coefficient of the source is consistent with theoretical predictions, although it is likely that non-linearity of the stellar surface brightness profile complicates the interpretation, especially for the I band. The global light curve fit to the data indicates that the event is due to a binary lens of a mass ratio q = 0.39 and a projected separation d = 2.42. The lens/source relative proper motion is (22.8 +_ 1.5) km/s/kpc, typical of bulge/bulge or bulge/disk events.

description: Abstract: "We study the asymptotic behaviour of radially symmetric solutions of the nonlocal equation [epsilon phi subscript t] - [epsilon delta phi] + 1/[epsilon]W(╠ü[phi]) - [lambda subscript epsilon](t) = 0 in a bounded spherically symmetric domain [omega][contained within] R[superscript n], where [lambda subscript epsilon](t) = 1/[epsilon] f[subscript omega]W(╠ü[phi])dx, with a Neumann boundary condition. The analysis is based on 'energy methods' combined with some a-priori estimates, the latter being used to approximate the solution by the first two terms of an asymptotic expansion. We only need to assume that the initial data as well as their energy are bounded. We show that, in the limit as [epsilon] -> 0, the interfaces move by a nonlocal mean curvature flow, which preserves mass. As a byproduct of our analysis, we obtain an L┬▓ estimate on the 'Lagrange multiplier' [lambda subscript epsilon](t). In addition we show rigorously that the nonlocal Ginzburg-Landau equation and the Cahn-Hilliard equation occur as special degenerate limits of a viscous Cahn-Hilliard equation."

description: No abstracts are to be cited without prior reference to the author.Cephalopods represent a very significant fishing resource in Mauritania. In particular, Octopus vulgaris (Cuvier 1797) whose value increases according to weight is the most valuable species. The resource shows significant inter annual variations in abundance related to the varying environmental conditions off Mauritania and the previously conducted species stock assessments indicate a state of overexploitation and growth over fishing. A bioeconomic single species population dynamics model is developed to estimate the combined impact of fishing closure duration and timing and minimum size at capture in various hypothetical exploitation scenarios to the yearly yield, value of yield and spawning stock biomass. Applying monthly cohort analysis in a Bayesian framework using MCMC sampling enabled us to implement the model with the variability observed in seasonal and inter annual environmental conditions and the uncertainty related to different aspects of the species biology. The currently applied management measure, a two-month closing season in September-October with a minimum size at capture of 500 g, is used as the reference point. The results indicate that the current timing of the closed season is optimal and no considerable gains in value of yield are obtained using other timings. However, increasing the minimum size at capture seems to be profitable. For example, minimum size of 1000 g with a two-month closing season in September-October yields a mean relative gain of 16 % in yearly value of yield. The findings of this study will contribute to the sustainable use of cephalopod fishery resources in Mauritania by providing indicators for the economically optimal harvest of the species. The methodology applied in this study aims to be applicable also to other cephalopods fisheries. This paper was prepared as part of EU 6th framework programme project “Probabilistic assessment, management and advice model for fishery management in the case of poor data availability” (POORFISH), contract no. 22745.

description: We investigate the low-energy properties of N-leg integer-spin ladders and tubes with an antiferromagnetic (AF) intrachain coupling. In the odd-leg tubes, the AF rung coupling causes the frustration. To treat all ladders and tubes systematically, we apply Sénéchal's method [Phys. Rev. B 52, 15319 (1995)], based on the nonlinear sigma model. This strategy is valid in the weak interchain (rung) coupling regime. We show that all frustrated tubes possess six-fold degenerate spin-1 magnon bands, as the lowest excitations, while other ladders and tubes have a standard triply degenerate bands. We also consider effects of four kinds of Zeeman terms: uniform, staggered only along the rung, only along the chain, or both directions. The above prediction of the no-field case implies that a sufficiently strong uniform field yields a two-component Tomonaga-Luttinger liquid (TLL) due to the condensation of doubly degenerate lowest magnons in frustrated tubes. In contrast, the field induces a standard one-component TLL in all other systems. This is supported by symmetry and bosonization arguments based on the Ginzburg-Landau theory. The bosonization also suggests that the two-component TLL vanishes and a one-component TLL appears, when the uniform field becomes larger for the second lowest magnon bands to touch the zero-energy line. This transition could be observed as a cusp singularity in the magnetization process. All the analyses for the systems with a staggered Zeeman term suggest that the emergence of the doubly degenerate transverse magnons and the single longitudinal one is universal for the one-dimensional AF spin systems with weak staggered field.

description: The International Cosmic Day (ICD) is an astroparticle physics outreach event for high-school students and brings together students and different physics outreach projects from all over the world. Groups of scientists, teachers, and students meet for one day to learn about cosmic rays and perform an experiment with atmospheric muons. All participating groups investigate an identical question. The students are enabled to work together like in an international collaboration, discussing their results in joint video conferences. Analyzing data, comparing and discussing with other "young scientists" gives the students a glimpse of how professional scientific research works. Scientists join the video conferences and give lectures to provide an insight in current astroparticle physics research. Several participating research experiments analyze big science data tailored to the questions addressed by the students and present their results on equal terms with the students. To create a lasting event, proceedings with measurement results of all participating groups are published. Every participant receives a personal e-mail with his certificate and the proceedings booklet. Organized by DESY in cooperation with Netzwerk Teilchenwelt, IPPOG, QuarkNet, Fermilab, and national partners like INFN, the ICD is a growing event with more and more popularity. We present the organization of the event and the experience from five years of ICD.

description: In this article, the Mo-Mn dual phase steel and its process parameters in hot rolling are discussed. The process window was derived by combining the experimental work in a hot deformation dilatometer and numerical calculation of process parameters using rate law models for ferrite and martensite transformation. The ferrite formation model is based on the Leblond and Devaux approach while martensite formation is based on the Koistinen-Marburger (K-M) formula. The carbon enrichment during ferrite formation is taken into account for the following martensite formation. After the completion of the parameter identification for the rate law model, the evolution of phases in multiphase steel can be addressed. Particularly, the simulations allow for predicting the preferable degree of retained strain and holding temperature on the run out table (ROT) for the required ferrite fraction.
title: Fisheries-independent estimates of trends in North Sea plaice (Pleuronectesplatessa) abundance: a Bayesian analysis of research vessel survey data

description: No abstracts are to be cited without prior reference to the author.We present fisheries-independent estimates of trends in North Sea plaice abundance and compare those with trends from conventional ICES assessments. Our estimates are obtained by Bayesian analysis of age disaggregated indices of abundance from three research vessel surveys: two beam trawl surveys, providing information on the southern and the central North Sea from 1985 and 1996 onwards, respectively, and the sole net survey, providing information on the coastal zones since 1970. Although each survey relates to a different subpopulation, together they cover the distribution area of the North Sea plaice stock. We use a separable model with regard to fishing mortality and model the temporal component of fishing mortality as a stochastic process. Moreover, we allow for the possibility of a changing exploitation pattern over time and consider the integration of the different survey data in a metapopulation model. Our results are partly in agreement with the most recent ICES assessment, where spawning stock biomass is estimated to have declined during the 1990s. However, the conventional assessment shows a temporary increase in the early 2000s whereas our results suggest the temporary recovery took place in the late 1990s. We support the finding that older fish seem to be less affected by fishing effort in recent years than they were before. The dependence on a relatively small sample size is generally viewed as the biggest disadvantage in performing survey-based assessments. Our analysis demonstrates the usefulness of Bayesian analysis as a flexible tool for extracting integrated signals from disaggregated survey data.

On calmness conditions in convex bilevel programming

description: In this article we compare two different calmness conditions which are widely used in the literature on bilevel programming and on mathematical programs with equilibrium constraints. In order to do so, we consider convex bilevel programming as a kind of intersection between both research areas. The so-called partial calmness concept is based on the function value approach for describing the lower level solution set. Alternatively, calmness in the sense of multifunctions may be considered for perturbations of the generalized equation representing the same lower level solution set. Both concepts allow to derive first order necessary optimality conditions via tools of generalized differentiation introduced by Mordukhovich. They are very different, however, concerning their range of applicability and the form of optimality conditions obtained. The results of this paper seem to suggest that partial calmness is considerably more restrictive than calmness of the perturbed generalized equation. This fact is also illustrated by means of a dicretized obstacle control problem.

description: The properties of nearby galaxy clusters limit the range of cosmological parameters consistent with our universe. We describe the limits which arise from studies of the intracluster medium (ICM) mass fraction fICM and consideration of the possible sources of systematic error: Omega_M<0.44h_{50}^{-1/2} at 95% confidence. We emphasize that independent of Type Ia supernovae (SNe Ia) observations, this cluster study, taken together with published cosmic microwave background (CMB) anisotropy studies, indicates a non-zero quintessence or dark energy component Omega_Q>0. We then discuss future galaxy cluster surveys which will probe the abundance of galaxy clusters to intermediate and high redshift. We investigate the sensitivity of these surveys to the cosmological density parameter Omega_M and the equation of state parameter w of any quintessence component. In particular, we show that cluster survey constraints from a proposed large solid angle X-ray survey are comparable in precision and complementary in nature to constraints expected from future CMB anisotropy and SNe Ia studies.

description: We determined how reproductive failure impacts the long-term profitability of beef cows in spring- and fall-calving herds. Simulation models were established to generate distributions of net present value, payback periods, and breakeven prices of calves when a dam fails to wean zero, one, or two calves over her life. Results indicate that giving a dam another calving opportunity after failing to wean a calf would likely result in her being unprofitable. A producer would be better off selling the open dam than giving her another chance to breed. This illustrates the value in selecting replacement heifers based on fertility.
Coherent structures in high-reynolds number wall-bounded turbulence: invariant solutions and scale interaction
Creators: name: Doohan, Patrick
Publisher: name: Imperial College London
Year: 2020

description: This work seeks to address some of the outstanding issues in the theoretical description of high-Reynolds number wall-bounded turbulence, with an emphasis on coherent structures and their dynamics. An inner-scaled shear stress-driven flow is introduced as a model of independent mesolayer turbulence as the friction Reynolds number tends to infinity, given that the effects of the flow geometry are negligible in this limit. The universal mesolayer dynamics are subsequently investigated from a dynamical systems perspective and through statistical analysis. Fifteen invariant solutions are computed in the minimal unit of near-wall turbulence, which capture all three stages of the self-sustaining process that underpins the dynamics at each integral lengthscale of motion. The temporal dynamics of near-wall flow with two integral lengthscales of motion are then analysed from a statistical perspective, with a focus on scale interaction. It is observed that the dynamics of the energy cascade from large to small scales are entirely determined by the large-scale self-sustaining process, while the feeding of energy from small to large scales is impelled by the small-scale self-sustaining process. Furthermore, a new scale interaction process is discovered, namely that wall-normal energy transfer from large to small scales drives small-scale turbulent production through the Orr mechanism. Finally, this minimal unit of multi-scale near-wall turbulence is also analysed from a dynamical systems perspective and twenty-eight invariant solutions are computed, which represent either the large- or small-scale self-sustaining processes. A solution that captures the feeding of streamwise energy from small to large scales and the resulting localised large-scale turbulent production is presented, both of which are supported by the subharmonic sinuous streak instability mode. However, none of the reported solutions fully capture the turbulent dynamics and in the absence of multi-scale invariant solutions, the dynamical systems description of the minimal unit of multi-scale near-wall turbulence is inadequate.

description: We calculate the linear response thermopower S of a quantum point contact using the Landauer formula and therefore assume non-interacting electrons. The purpose of the paper, is to compare analytically and numerically the linear thermopower S of non-interacting electrons to the low temperature approximation, S^1=(pi^2/3e)k^2 T d(ln G(mu,T=0))/dmu, and the so-called Mott expression, S^M=(pi^2/3e)k^2 T d(ln G(mu,T))/dmu, where G(mu,T) is the (temperature dependent) conductance. This comparison is important, since the Mott formula is often used to detect deviations from single-particle behavior in the thermopower of a point contact.
