description: Space radiation is well-known to pose serious issues to solid-state high-energy sensors. Therefore, radiation models play a key role in the preventive assessment of the radiation damage, duty cycles, performance and lifetimes of detectors. In the context of HERMES-SP mission we present our investigation of AE8/AP8 and AE9/AP9 specifications of near-Earth trapped radiation environment. We consider different circular Low-Earth orbits. Trapped particles fluxes are obtained, from which maps of the radiation regions are computed, estimating duty cycles at different flux thresholds. Outcomes are also compared with published results on in-situ measurements.

description: We measure the mean halo-mass of z=0.5 MgII absorbers using the cross-correlation (over co-moving scales 0.05-13h^{-1}Mpc) between 1806 MgII quasar absorption systems and ~250,000 Luminous Red Galaxies (LRGs), both selected from the SDSS DR3. The MgII systems have rest-frame equivalent widths W_r(2796)>=0.3A. From the ratio of the MgII-LRG cross-correlation to the LRG-LRG auto-correlation, we find that the bias ratio between MgII absorbers and LRGs is 0.65+/-0.08, which implies that the absorber host-galaxies have a mean halo-mass 20-40 times smaller than that of the LRGs; the MgII absorbers have halos of mean mass =11.94+/-0.31(stat)+/-0.25(sys). We demonstrate that this statistical technique, which does not require any spectroscopic follow-up, does not suffer from contaminants such as stars or foreground and background galaxies. Finally, we find that the absorber halo-mass is anti-correlated with the equivalent width. If MgII absorbers were virialized in galaxy halos a positive M_h-W_r correlation would have been observed since W_r(2796) is a direct measure of the velocity spread of the MgII sub-components. Thus, our results demonstrate that the individual clouds of a MgII system are not virialized in the gaseous halos of the host-galaxies. We review past results in the literature on the statistics of MgII absorbers and find that they too require an M_h-W_r anti-correlation. When combined with measurements of the equivalent width distribution, the M_h-W_r anti-correlation naturally explains why absorbers with W_r(2796)>=2A are not seen at large impact parameters. We interpret the M_h-W_r anti-correlation within the starburst scenario where strong MgII absorbers are produced by supernovae-driven winds.

description: Graphene-based materials (GBMs) constitute a large family of materials which has attracted great interest for potential applications. In this work, we apply first-principles calculations based on density functional theory (DFT) and fully atomistic reactive molecular dynamics (MD) simulations to study the structural and electronic effects of hydrogenation in Me-graphene, a non-zero bandgap GBM composed of both $sp^2$ and $sp^3$-hybridized carbon. Our DFT results show a substantial tuning of the electronic properties of Me-graphene by hydrogenation, with the bandgap varying from $0.64$ eV to $2.81$ eV in the GGA-PBE approach, passing through metallic ground-states and a narrower bandgap state depending on the hydrogen coverage. The analyses of structural properties and binding energies have shown that hydrogenated Me-graphene presents strong and stable \ce{C-H} bonds, and all of the carbon atoms are in $sp^3$ hybridization resulting in a boat-like favorable conformation for fully-hydrogenated Me-graphene. Our MD simulations have indicated that the hydrogenation of Me-graphene is temperature-dependent, and the covalent adsorption tends to grow by islands. Those simulations also show that the most favorable site, predicted by our DFT calculations, acts as trigger adsorption for the extensive hydrogenation.

description: Most existing person re-identification methods compute pairwise similarity by extracting robust visual features and learning the discriminative metric. Owing to visual ambiguities, these content-based methods that determine the pairwise relationship only based on the similarity between them, inevitably produce a suboptimal ranking list. Instead, the pairwise similarity can be estimated more accurately along the geodesic path of the underlying data manifold by exploring the rich contextual information of the sample. In this paper, we propose a lightweight post-processing person re-identification method in which the pairwise measure is determined by the relationship between the sample and the counterpart's context in an unsupervised way. We translate the point-to-point comparison into the bilateral point-to-set comparison. The sample's context is composed of its neighbor samples with two different definition ways: the first order context and the second order context, which are used to compute the pairwise similarity in sequence, resulting in a progressive post-processing model. The experiments on four large-scale person re-identification benchmark datasets indicate that (1) the proposed method can consistently achieve higher accuracies by serving as a post-processing procedure after the content-based person re-identification methods, showing its state-of-the-art results, (2) the proposed lightweight method only needs about 6 milliseconds for optimizing the ranking results of one sample, showing its high-efficiency.

description: We derive a general relation between the non-analyticities of the ground state energy and those of a subclass of the multipartite generalized global entanglement (GGE) measure defined by T. R. de Oliveira et al. [Phys. Rev. A 73, 010305(R) (2006)] for many-particle systems. We show that GGE signals both a critical point location and the order of a quantum phase transition (QPT). We also show that GGE allows us to study the relation between multipartite entanglement and QPTs, suggesting that multipartite but not bipartite entanglement is favored at the critical point. Finally, using GGE we were able, at a second order QPT, to define a diverging entanglement length (EL) in terms of the usual correlation length. We exemplify this with the XY spin-1/2 chain and show that the EL is half the correlation length.

Forme romanesque et contestation de l’histoire dans La fille de Christophe Colomb de Réjean Ducharme
Creators: name: Hobbs, Sandra Claire
Publisher: name: University of British Columbia
Year: 2009

description: La Fille de Christophe Colomb (Paris: Gallirnard, 1969) is a novel written by Rejean Ducharme in rhyming verse resembling an epic poem In this thesis, it will be shown that the form of the novel serves to emphasize the contestation of History evident in the novel's content. While this novel is certainly unusual in Ducharme's work it fits into the ambiant literary discourse of Quebec in the 1960's, where the theories of decolonisation influenced writers and critics alike. In particular, History was seen to be imposed on Quebec from the outside; Quebec must necessarily reject this History and begin to make its own. This underlying assumption for the analysis proposed in this thesis will be demonstrated in Chapter One through reflections by Ducharme's contemporaries, existing criticism of La Fille de' Christophe Colomb, and by current theories of postcolonial writing. In Chapter Two, the epic form of the novel will be studied in detail. On the surface, the author appears to respect the "rules" of the genre, but a close reading of the text will show that this respect is only superficial, and that the rules are subverted to create tension between literary norms and Ducharme's writing. It is the narrative structure of the novel, however, that proves to be the most subversive deviation from the norms of the epic poem: although the majority of the novel is narrated in the third person, a substantial fragmentation of the narrative voice occurs which will be demonstrated in Chapter Three. The net impact of this fragmentation is to produce a conflict between the codes of the epic poem and the novel. At the end of the analysis of the relationship between literary form and contestation of History in La Fille de Christophe Colomb, it will be shown that the form, as an element separate from the content, conveys a problematic relationship between this text and History. The novel contributes to the contestation of History as practised in the literature of Quebec in the 1960's by subverting the literary code, thereby linking literary history to History as colonizing factors that are questioned in this novel.
Probing the structure of protoplanetary disks: a comparative study of DM Tau, LkCa 15 and MWC 480

description: We report sub-arcsec CO observations of the disks around MWC 480, LkCa 15 and DM Tau, and simultaneous measurements of HCO+ J=1-0. We derive the disk properties by fitting a standard disk model, with all parameters power laws of the distance to the star. Biases are explained and discussed. We find evidence for vertical temperature gradient in the disks of MWC 480 and DM Tau, as in AB Aur, but not in LkCa 15. The disks temperature increase with stellar effective temperature. Most of the CO gas is at temperatures smaller than 17 K, the condensation temperature on grains. The scale height of the CO distribution appears larger (by 50%) than the hydrostatic scale height. The more UV luminous stars have more CO, but there is no simple dependency of CO abundance and isotopologue ratio with stellar type. The 13CO/HCO+ ratio is around 600. The temperature behaviour is consistent with expectations, but published chemical models have difficulty reproducing the observed CO quantities. Vertical mixing and photo-dissociation at the disk outer edge seem important chemical agents. The CO data suggest a more complex surface density distribution than assumed in models.

description: The transition from the diffuse warm neutral medium (WNM) to the dense cold neutral medium (CNM) is what set the initial conditions to the formation of molecular clouds. The properties of the turbulent cascade in the WNM, essential to describe this radiative condensation process, have remained elusive in part due to the difficulty to map out the structure and kinematics of each H I thermal phases. Here we present an analysis of a 21 cm hyper-spectral data cube from the GHIGLS HI survey where the contribution of the WNM is extracted using ROHSA, a Gaussian decomposition tool that includes spatial regularization. The distance and volume of the WNM emission is estimated using 3D dust extinction map information. The thermal and turbulent contributions to the Doppler line width of the WNM were disentangled using two techniques, one based on the statistical properties of the column density and centroid velocity fields, and another on the relative motions of CNM structures as a probe of turbulent motions. We found that the volume of WNM sampled here, located at the outer edge of the Local Bubble, shows thermal properties in accordance with expected values for heating and cooling processes typical of the Solar neighbourhood. The WNM has the properties of sub/trans-sonic turbulence, with a turbulent Mach number at the largest scale probed here (l = 130 pc) of Ms = 0.87 +- 0.15, a density contrast of 0.6 +- 0.2, and velocity and density power spectra compatible with k-11/3. The low Mach number of the WNM provides dynamical conditions that allows the condensation mode of thermal instability (TI) to grow freely and form CNM structures, as predicted by theory.

description: Recently Liu and Wang derived the likelihood ratio test (LRT) statistic and its asymptotic distribution for testing equality of two multinomial distributions vs. the alternative that the second distribution is larger in terms of increasing convex order (ICX). ICX is less restrictive than stochastic order and is a notion that has found applications in insurance and actuarial science. In this paper we propose a new test for ICX. The new test has several advantages over the LRT and over any test procedure that depends on asymptotic theory for implementation. The advantages include the following: (i) The test is exact (non-asymptotic). (ii) The test is performed by conditioning on marginal column totals (and row totals in a full multinomial model for a $2\times C$ table). (iii) The test has desirable monotonicity properties. That is, the test is monotone in all practical directions (to be formally defined). (iv) The test can be carried out computationally with the aid of a computer program. (v) The test has good power properties among a wide variety of possible alternatives. (vi) The test is admissible. The basis of the new test is the directed chi-square methodology developed by Cohen, Madigan, and Sackrowitz.

Using only the continuity assumption, we prove a new composition result of $μ$-pseudo almost periodic functions in Stepanov sense. Moreover, we present different applications to semilinear differential equations and inclusions in Banach spaces with weak regular forcing terms. We prove the existence and uniqueness of $μ$-pseudo almost periodic solutions (in the strong sense) to a class of semilinear fractional inclusions and semilinear evolution equations, respectively, provided that the nonlinear forcing terms are only Stepanov $ μ$-pseudo almost periodic in the first variable and not a uniformly strict contraction with respect to the second argument. Some examples illustrating our theoretical results are also presented.

description: We present an experimental study of the lattice induced light shifts on the 1S_0-3P_0 optical clock transition (v_clock~518 THz) in neutral ytterbium. The ``magic'' frequency, v_magic, for the 174Yb isotope was determined to be 394 799 475(35)MHz, which leads to a first order light shift uncertainty of 0.38 Hz on the 518 THz clock transition. Also investigated were the hyperpolarizability shifts due to the nearby 6s6p 3P_0 - 6s8p 3P_0, 6s8p 3P_2, and 6s5f 3F_2 two-photon resonances at 759.708 nm, 754.23 nm, and 764.95 nm respectively. By tuning the lattice frequency over the two-photon resonances and measuring the corresponding clock transition shifts, the hyperpolarizability shift was estimated to be 170(33) mHz for a linear polarized, 50 uK deep, lattice at the magic wavelength. In addition, we have confirmed that a circularly polarized lattice eliminates the J=0 - J=0 two-photon resonance. These results indicate that the differential polarizability and hyperpolarizability frequency shift uncertainties in a Yb lattice clock could be held to well below 10^-17.

description: Neuromorphic computing with spintronic devices has been of interest due to the limitations of CMOS-driven von Neumann computing. Domain wall-magnetic tunnel junction (DW-MTJ) devices have been shown to be able to intrinsically capture biological neuron behavior. Edgy-relaxed behavior, where a frequently firing neuron experiences a lower action potential threshold, may provide additional artificial neuronal functionality when executing repeated tasks. In this study, we demonstrate that this behavior can be implemented in DW-MTJ artificial neurons via three alternative mechanisms: shape anisotropy, magnetic field, and current-driven soft reset. Using micromagnetics and analytical device modeling to classify the Optdigits handwritten digit dataset, we show that edgy-relaxed behavior improves both classification accuracy and classification rate for ordered datasets while sacrificing little to no accuracy for a randomized dataset. This work establishes methods by which artificial spintronic neurons can be flexibly adapted to datasets.

description: Grazing-incidence fast atom diffraction (GIFAD) is an exceptionally sensitive method for surface analysis, which can be applied not only at room temperature but also at higher temperatures. In this work we use the He-LiF(001) system as benchmark to study the influence of temperature on GIFAD patterns from insulator surfaces. Our theoretical description is based on the Phonon-Surface Initial Value Representation (P0-SIVR) approximation, which is a semiquantum approach that includes the phonon contribution to the elastic scattering. Within the P0-SIVR approach the main features introduced by thermal lattice vibrations on the angular distributions of scattered projectiles are investigated as a function of the crystal temperature. We found that azimuthal and polar spectra are strongly affected by thermal fluctuations, which modify the relative intensities and the polar spread of the interference structures. These findings are relevant for the use of GIFAD in surface research. Moreover, the present results are contrasted with available experimental data at room temperature.

description: This paper presents a trajectory tracking control strategy that modulates the active power injected by geographically distributed inverter-based resources to support transient stability. Each resource is independently controlled, and its response drives the local bus voltage angle toward a trajectory that tracks the angle of the center of inertia. The center-of-inertia angle is estimated in real time from wide-area measurements. The main objectives are to stabilize transient disturbances and increase the amount of power that can be safely transferred over key transmission paths without loss of synchronism. Here we envision the actuators as utility-scale energy storage systems; however, equivalent examples could be developed for partially-curtailed photovoltaic generation and/or Type 4 wind turbine generators. The strategy stems from a time-varying linearization of the equations of motion for a synchronous machine. The control action produces synchronizing torque in a special reference frame that accounts for the motion of the center of inertia. This drives the system states toward the desired trajectory and promotes rotor angle stability. For testing we employ a reduced-order dynamic model of the North American Western Interconnection. The results show that this approach improves system reliability and can increase capacity utilization on stability-limited transmission corridors.

The lower bound is given in terms of Kraus operators of the quantum noise. This result is then used to analyze the average error correcting performance of codes that are randomly drawn from unitarily invariant code ensembles. Our results confirm that random codes of sufficiently large block size are highly suitable for quantum error correction. Moreover, employing a lemma of Bennett, Shor, Smolin, and Thapliyal, we prove that random coding attains information rates of the regularized coherent information.

Adolescent perspectives on prenatal education : A qualitative study
Creators: name: Brawner, Suzanne Marcia
Publisher: name: University of British Columbia
Year: 2009

description: The rate of adolescent pregnancy is on the rise in British Columbia. As health care professionals encounter adolescents in a variety of settings, they are increasingly likely to be providing prenatal care and education for the adolescent population. Research studies have documented numerous physical and psychological risks with early childbearing. In addition, research findings support that a woman's ability to adapt to pregnancy depends on the individual's beliefs past life experiences and ways of perceiving the pregnancy experience. However, Kleinman's conceptual framework of explanatory models (1978) advocates that the beliefs, expectations and desires of the adolescent client during the prenatal period may be quite different from those perceived by health providers. Because the knowledge of adolescent pregnancy almost exclusively reflects the perspectives of the health care provider, this study attempts to identify and explore the adolescents' perspective about pregnancy and prenatal education from teens themselves. With the assistance of the Vancouver Health Department and Maywood Pregnancy Outreach Program, nineteen, pregnant and single teenagers were recruited to attend one of three focus group discussions. The adolescents chose to describe their emotional response to pregnancy, previous experiences with prenatal education and their vision for adolescent prenatal education. Direction for data examination was taken from Giorgi's (1975) and Knafl and Webster's (1988) guidelines for data management and analysis. Data analysis revealed pregnant adolescents experience a transition of emotional responses throughout pregnancy including: denial, shock and disbelief, ignorance, hopelessness, abandonment and isolation, dependency, powerlessness and anticipation and pride. In addition, adolescents perceive societal attitudes towards pregnant teens as "negative", "judgemental" and "all-knowing". Study participants described and defined their own learning needs for prenatal education. Adolescent learning needs addressed structure, content and teaching strategy for prenatal programs. The explanatory model operating in the adolescents' mind about prenatal education differed from that of health professionals in terms of: the definition of who provides education and care, preparation and readiness for pregnancy and parenthood, program format and duration and choice and delivery methods of prenatal care and education. The findings from this study have implications for all health disciplines regarding practice issues and direction for future research.

In an effort to understand what makes adolescent sexual offenders different from other delinquents. I will examine the victimization experiences (sexual abuse and physical abuse) and the family dynamics (family violence, family incarceration and family structure) of both adolescent sexual offenders and nonsexual offenders. The research question is: what factors contribute to each group of delinquency the most? Although all of the factors influence delinquency, victimization is expected to be the most influential. This study utilized data from The Survey of Youth in Custody, 1987; a national representative sample of children in custody in the United States. Frequency distributions and crosstabular analysis and was utilized to determine which variables are related to delinquency.

description: Raman micro/macro-spectroscopy allows for a non-destructive remote analysis: body and glaze, crystalline and amorphous phases can be identified, including the nanosized pigments colouring the glaze. Last generation instruments are portable which allows for examination in museum, on sites, etc. This paper gives an overview on the potential of Raman spectrometry technique to analyze ancient ceramics and glasses. Selected glasses as well as glazes of various porcelains, celadon, faiences and potteries, representative of the different production technologies used in the Antique, European, Mediterranean, Islamic and Asian worlds were studied. Their identification is based on the study of the Raman fingerprint of crystalline and glassy phases. Raman parameters allow for the classification as a function of composition and/or processing temperature. Special attention is given to the spectra of amorphous and coloring phases (pigment).

description: The rheological behaviors of suspension of ideally conductive particles in an electric field are studied using large-scale numerical simulations in the limit of zero-shear-rate flow. Under the action of an electric field, the particles undergo the nonlinear electrokinetic phenomenon termed as dipolophoresis, which is the combination of dielectrophoresis and induced-charge electrophoresis. For ideally conductive particles, the dynamics of the suspension are primarily controlled by induced-charge electrophoresis. To characterize the rheological properties of the suspension, the particle stress tensor and particle pressure are calculated in a range of volume fraction up to almost random close packing. The particle normal stress and particle pressure are shown to behave non-monotonically with volume fraction, especially in concentrated regimes. In particular, the particle pressure is positive for volume fraction up to 30\%, after which it becomes negative, indicating a change in the nature of the particle pressure. The microstructure expressed by pair distribution function and suspension entropy is also evaluated. Visible variations in the local microstructure seem to correlate with the non-monotonic variation in the particle normal stresses and particle pressure. These non-monotonic behaviors are also correlated with the change in the dominant mechanism of particle pairing dynamics observed in our recent study [Mirfendereski \& Park, J. Fluid Mech. \textbf{875}, R3 (2019)]. Lastly, the effects of confinement on the particle stress and particle pressure are investigated. It is found that the particle pressure changes its nature very quickly at high volume fractions as the level of confinement increases. This study should motivate control strategies to fully exploit the distinct changing nature of the pressure for rheological manipulation of such suspension system.

description: We study the coupled Hartree system $$ \left\{\begin{array}{ll} -Δu+ V_1(x)u =α_1\big(|x|^{-4}\ast u^{2}\big)u+β\big(|x|^{-4}\ast v^{2}\big)u &\mbox{in}\ \mathbb{R}^N,\\[1mm] -Δv+ V_2(x)v =α_2\big(|x|^{-4}\ast v^{2}\big)v +β\big(|x|^{-4}\ast u^{2}\big)v &\mbox{in}\ \mathbb{R}^N, \end{array}\right. $$ where $N\geq 5$, $β>\max\{α_1,α_2\}\geq\min\{α_1,α_2\}>0$, and $V_1,\,V_2\in L^{N/2}(\mathbb{R}^N)\cap L_{\text{loc}}^{\infty}(\mathbb{R}^N)$ are nonnegative potentials. This system is critical in the sense of the Hardy-Littlewood-Sobolev inequality. For the system with $V_1=V_2=0$ we employ moving sphere arguments in integral form to classify positive solutions and to prove the uniqueness of positive solutions up to translation and dilation, which is of independent interest. Then using the uniqueness property, we establish a nonlocal version of the global compactness lemma and prove the existence of a high energy positive solution for the system assuming that $|V_1|_{L^{N/2}(\mathbb{R}^N)}+|V_2|_{L^{N/2}(\mathbb{R}^N)}>0$ is suitably small.

description: The paper reports on the Raman/fluorescence study of melt-grown Al2O3/GdAlO3 eutectic composites. Raman bands from the -alumina and gadolinium perovskite phases identified by X-ray diffraction were systematically observed together in the domains optically visible, even when the latter were much larger than the Raman probe. This suggests a more complex interlocking pattern than appearing on SEM or optical microscopy images. The polarization of alumina and GdAlO3 Raman bands evidenced the preferential orientation of Al2O3 phase with respect to the sample growth direction, in agreement with TEM results. In addition, the position of chromium impurity fluorescence bands was used to map the residual stress in alumina phase. It is a compression in the 200-300 MPa range.

description: Nonreciprocity can be passively achieved by harnessing material nonlinearities. In particular, networks of nonlinear bistable elements with asymmetric energy landscapes have recently been shown to support unidirectional transition waves. However, in these systems energy can be transferred only when the elements switch from the higher to the lower energy well, allowing for a one-time signal transmission. Here, we show that in a mechanical metamaterial comprising a 1D array of bistable arches nonreciprocity and reversability can be independently programmed and are not mutually exclusive. By connecting shallow arches with symmetric energy wells and decreasing energy barriers, we design a reversible mechanical diode that can sustain multiple signal transmissions. Further, by alternating arches with symmetric and asymmetric energy landscapes we realize a nonreciprocal chain that enables propagation of different transition waves in opposite directions.

Mixed state of a lattice d-wave superconductor

description: We study the mixed state in an extreme type-II lattice d-wave superconductor in the regime of intermediate magnetic fields H_{c1} << H << H_{c2}. We analyze the low energy spectrum of the problem dominated by nodal Dirac-like quasiparticles with momenta near k_F=(\pm k_D,\pm k_D) and find that the spectrum exhibits characteristic oscillatory behavior with respect to the product of k_D and magnetic length l. The Simon-Lee scaling, predicted in this regime, is satisfied only on average, with the magnitude of the oscillatory part of the spectrum displaying the same 1/l dependence as its monotonous ``envelope'' part. The oscillatory behavior of the spectrum is due to the inter-nodal interference enhanced by the singular nature of the low energy eigenfunctions near vortices. We also study a separate problem of a single vortex piercing an isolated superconducting grain of size L by L. Here we find that the periodicity of the quasiparticle energy oscillations with respect to k_D L is doubled relative to the case where the field is zero and the vortex is absent, both such oscillatory behaviors being present at the leading order in 1/L. Finally, we review the overall features of the tunneling conductance experiments in YBCO and BSCCO, and suggest an interpretation of the peaks at 5-20 meV observed in the tunneling local density of states in these materials.

description: In this paper, we discuss recent progress in magnet-free non-reciprocal structures based on a synthetic form of angular momentum bias imparted via spatiotemporal modulation. We discuss how such components can support metrics of performance comparable with traditional magnetic-biased ferrite devices, while at the same time offering distinct advantages in terms of reduced size, weight, and cost due to the elimination of magnetic bias. We further provide an outlook on potential applications and future directions based on these components, ranging from wireless full-duplex communications to metasurfaces and topological insulators.

description: Aim of the diplomatic work is the study of conditions of validity and terms of energy in the real legal acts. In the first part, which is reported generally in real legal acts, are examined initially the conditions of validity and the consequences of the invalidity ( / of cancellation ) of real legal acts, while afterwards are presented the terms of energy and the consequences of inactive real legal acts. In the second part, which is reported at individual forms of real legal acts on movable and immovable property, are examined more specifically the terms of validity and energy in legal acts that have as object the property (possession of property, resignation from the property, donation of real estate mortis causa ), the easements ( /servitudes ) (land and personal/ appurtenant and in gross), the pledge and the mortgage. The theoretical analysis is framed in individual subjects by references in decisions of courts of native land, from which it results the corresponding jurisprudential confrontation of questions that occupied greek science.

description: An optimized method for estimating path-ensemble averages using data from processes driven in opposite directions is presented. Based on this estimator, bidirectional expressions for reconstructing free energies and potentials of mean force from single-molecule force spectroscopy - valid for biasing potentials of arbitrary stiffness - are developed. Numerical simulations on a model potential indicate that these methods perform better than unidirectional strategies.
