description: [transcription] A Nîmes le 8e mars 1773.
Mon cher Monsieur,
Je ne comptais pas pouvoir aller à Aubais qu’après le Carême, mais comme ma douleur de rhumatisme m’ont quitté, je pars aujourd’hui pour m’y rendre. J’y serai au moins pour une quinzaine de jours, ainsi si vous avez envie et loisir d’y venir pendant que j’y serai, j’en aurai beaucoup de satisfaction. Si cependant vos affaires ne vous permettaient pas de vous y transporter, je vous y offre mes services pour tout ce qui peut vous y être utile. En adressant votre lettre à Lunel pour le château d’Aubais, elle me sera rendue. Je n’ai pas voulu partir sans vous donner cette information.
Mes respects à Monsieur votre père qui nous donna à peine le temps de contester le désir que nous avions de le voir. Je lui remis les livres que vous m’aviez demandés. Je garde devers moi la Bibliothèque physique de la France que je vous renverrai dans quelque temps. Vous aurez eu, je pense, le soin de remettre à Monsieur Gouan, le volume de la Bibliotheca botanica de Haller que je vous adressai pour lui. Je ne vous en dis pas davantage. Je vais partir. Je suis pour la vie votre bon serviteur.
Séguier
[fol. 119r] A Monsieur,
Monsieur L’Amoureux le fils docteur
En médecine, près le gouvernement

description: No abstracts are to be cited without prior reference to the author.Postspawning blue whiting migrate from the spawning grounds west of the British Isles, past the Faroe Islands and into the feeding areas in the Norwegian Sea during the spring months March to early June. The changeable migratory route through Faroese waters, as inferred from fisheries statistics, is found to be closely linked to the hydrography along the Rockall Bank, as simulated by an ocean circulation model. A variable spawning intensity around the bank is suggested as the causal mechanism for this link. The observed variability is primarily governed by the strength and extent of the subpolar gyre. Utilizing apparent links between the atmospheric forcing and the subpolar gyre dynamics, the environmental spawning and recruitment conditions for the present (2007) season is forecasted.

description: We consider a Dp brane within a D9 brane in the presence of a B-field whose polarization is {\em transverse} to the Dp brane. To be definite, we take a D3-D9 system. It is observed that the system has the same pattern of supersymmetry breaking as that of a soliton of the six dimensional non-commutative gauge theory that is obtained by dimensional reduction of an {\cal N}=1, D=10 gauge theory. These results indicate that the soliton solution is the low energy realization of a D3 brane in a D9 brane with a transverse B-field, hence can be viewed as a generalization of the previous results in the literature where similar observations were made for lower codimensional cases.

description: Compared to single-phase heat transfer, two-phase microchannel heat sinks utilize latent heat to reduce the needed flow rate and to maintain a rather uniform temperature close to the boiling temperature. The challenge in the application of cooling for electronic chips is the necessity of modeling a large number of microchannels using large number of meshes and extensive computation time. In the present study, a modified porous media method modeling of two-phase flow in microchannels is performed. Compared with conjugate method, which considers individual channels and walls, it saves computation effort and provides a more convenient means to perform optimization of channel geometry. The porous media simulation is applied to a real chip. The channels of high heat load will have higher qualities, larger flow resistances, and lower flow rates. At a constant available pressure drop over the channels, the low heat load channels show much higher mass flow rates than needed. To avoid this flow maldistribution, the channel widths on a chip are adjusted to ensure that the exit qualities and mass flow rate of channels are more uniform. As a result, the total flow rate on the chip is drastically reduced, and the temperature gradient is also minimized. However, it only gives a relatively small reduction on the maximum surface temperature of chip.

description: By integrating the Young-Laplace equation, including the effects of gravity, we have calculated the equilibrium shape of the two-dimensional Plateau borders along which a vertical soap film contacts two flat, horizontal solid substrates of given wettability. We show that the Plateau borders, where most of a foam's liquid resides, can only exist if the values of the Bond number ${\rm Bo}$ and of the liquid contact angle $θ_c$ lie within certain domains in $(θ_c,{\rm Bo})$ space: under these conditions the substrate is foam-philic. For values outside these domains, the substrate cannot support a soap film and is foam-phobic. In other words, on a substrate of a given wettability, only Plateau borders of a certain range of sizes can form. For given $(θ_c,{\rm Bo})$, the top Plateau border can never have greater width or cross-sectional area than the bottom one. Moreover, the top Plateau border cannot exist in a steady state for contact angles above 90$^\circ$. Our conclusions are validated by comparison with both experimental and numerical (Surface Evolver) data. We conjecture that these results will hold, with slight modifications, for non-planar soap films and bubbles. Our results are also relevant to the motion of bubbles and foams in channels, where the friction force of the substrate on the Plateau borders plays an important role.

description: No abstracts are to be cited without prior reference to the author.Ocean temperatures in most parts of the world are increasing and are expected to continue to rise during the 21st century. A major challenge to ecologists and marine resource managers is to understand and predict how these global changes will affect species and ecosystems at local scales where temperature more directly affects biological responses and species interactions. Here, we investigate historical variability in regional sea surface temperature in two large heavily-exploited marine ecosystems and compare these variations with expected rates of temperature change for the 21st century. We use four of the world’s longest calibrated daily time series to show that trends in surface temperatures in the North and Baltic Seas now exceed those at any time since instrumented measurements began in 1861 and 1880. Temperatures in summer since 1985 have increased at nearly triple the global warming rate which is expected to occur during the 21st century and summer temperatures have risen 2-5 times faster than those in other seasons. These warm temperatures and rates of change are due partly to an increase in the frequency of extremely warm years. The recent warming event is exceeding the ability of local species to adapt and is consequently leading to major changes in the structure, function and services of these ecosystems.
New Gauss-Bonnet black holes with curvature induced scalarization in the extended scalar-tensor theories

description: In the present paper we consider a class of extended scalar-tensor-Gauss-Bonnet (ESTGB) theories for which the scalar degree of freedom is excited only in the extreme curvature regime. We show that in the mentioned class of ESTGB theories there exist new black hole solutions which are formed by spontaneous scalarization of the Schwarzaschild balck holes in the extreme curvature regime. In this regime, below certain mass, the Schwarzschild solution becomes unstable and new branch of solutions with nontrivial scalar field bifurcate from the Schwarzschild one. As a matter of fact, more than one branches with nontrivial scalar field can bifurcate at different masses but only the first one is supposed to be stable. This effect is quite similar to the spontaneous scalarization of neutron stars. In contrast with the standard spontaneous scalarization of neutron stars which is induced by the presence of matter, in our case the scalarization is induced by the curvature of the spacetime.

The Origin of Star Formation Gradients in Rich Galaxy Clusters

description: We examine the origin of clustercentric gradients in the star formation rates and colors of rich cluster galaxies within the context of a simple model where clusters are built through the ongoing accretion of field galaxies. The model assumes that after galaxies enter the cluster their star formation rates decline on a timescale of a few Gyrs, the typical gas consumption timescale of disk galaxies in the field. Such behaviour might be expected if tides and ram pressure strip off the gaseous envelopes that normally fuel star formation in spirals over a Hubble time. Combining these timescales with mass accretion histories derived from N-body simulations of cluster formation in a Lambda-CDM universe, we reproduce the systematic differences observed in the color distribution of cluster and field galaxies, as well as the strong suppression of star formation in cluster galaxies and its dependence on clustercentric radius. The simulations also indicate that a significant fraction of galaxies beyond the virial radius of the cluster may have been within the main body of the cluster in the past, a result that explains naturally why star formation in the outskirts of clusters (and as far out as two virial radii) is systematically suppressed relative to the field. The agreement with the data beyond the cluster virial radius is also improved if we assume that stripping happens within lower mass systems, before the galaxy is accreted into the main body of the cluster. We conclude that the star formation rates of cluster galaxies depend primarily on the time elapsed since their accretion onto massive virialized systems, and that the cessation of star formation may have taken place gradually over a few Gyrs.

description: The thermal conductivities of solid silicon thin films and silicon thin films with periodic pore arrays are predicted using a Monte Carlo technique to include phonon-boundary scattering and the Boltzmann transport equation. The bulk phonon properties required as input are obtained from harmonic and anharmonic lattice dynamics calculations. The force constants required for the lattice dynamics calculations are obtained from forces calculated using density functional theory. For both solid and porous films, the in-plane thermal conductivity predictions capture the magnitudes and trends of previous experimental measurements. Because the prediction methodology treats the phonons as particles with bulk properties, the results indicate that coherent phonon modes associated with the secondary periodicity of the pores do not contribute to thermal transport in porous films with feature sizes greater than 100 nm.

description: No abstracts are to be cited without prior reference to the author.One of the consequences of climate change is the world ocean warming. All the studies carried out in the Bay of Biscay agree that the region has warmed up during the last 20 years. Interestingly, some of them also report a cyclic component. But as these studies are mainly based on sea surface temperature they are insufficient to study this process at depth and they usually tend to explain this interannual variability only in relation to atmospheric forcing. Here we address the issue of exploring how the rate of sea warming changes in relation to the type of Central Waters found in the area at any moment. We found that during the early 2000s, the advection of a large volume of cooler and less saline waters from the inner part of the bay caused a general sinking of the isopycnals, reducing the rate of warming. During the last year, the process reversed due to the flow of warmer and saltier tropical waters which enhanced the warming. Based on these results, we propose a mechanism in which a wavering natural variability would superimpose on the steady global warming, modulating it. The combination of these two forcings would result in the non linear warming observed in the area. This interplay between the natural and the anthropogenic mode, which might be applicable to a broader area, highlights the role of the general circulation. This must be considered in order to accurately estimate the nature and rate of the sea surface warming, particularly when extrapolating into the future.

description: We present the growth dynamics of an island of particles $A$ injected from a localized $A$-source into the sea of particles $B$ and dying in the course of diffusion-controlled annihilation $A+B\to 0$. We show that in the 1d case the island unlimitedly grows at any source strength $Λ$, and the dynamics of its growth {\it does not depend} asymptotically on the diffusivity of $B$ particles. In the 3d case the island grows only at $Λ> Λ_{c}$, achieving asymptotically a stationary state ({\it static island}). In the marginal 2d case the island unlimitedly grows at any $Λ$ but at $Λ< Λ_{*}$ the time of its formation becomes exponentially large. For all the cases the numbers of surviving and dying $A$ particles are calculated, and the scaling of the reaction zone is derived.

description: We present deep imaging in the U, B and I bands obtained under excellent seeing conditions of the double quasar Q0151+048A,B and of the Damped Ly-alpha (DLA) absorbing galaxy at z(abs) = 1.9342 named S4. We analyse the data employing two separate and independent methods. First we deconvolve the images using the MCS algorithm, secondly we decompose the images via an object based iteration process where we fit models to objects without any attempt to improve the resolution of the data. Our detailed analysis of the images reveals, somewhat surprisingly, that extended objects centred on the quasars themselves are much brighter continuum sources than the DLA galaxy. Due to the complexity caused by the many superimposed objects, we are unable to certify whether or not continuum emission from the DLA galaxy is detected. Continuum emission from the extended objects centred on the positions of the quasars is clearly seen, and the objects are tentatively identified as the ``host galaxies'' of the quasars. The flux of those host galaxies is of order 2--6% of the quasar flux, and the light profile of the brighter of the two is clearly best fit with a de Vaucouleurs profile. We discuss two alternative interpretations of the origin of the extended flux: i) the early stage of a massive elliptical galaxy in the process of forming the bulk of its stars, and ii) quasar light scattered by dust.

The optical conductivity shows two broad interband transition peaks at 1.6 eV and 3.2 eV, and a weak midinfrared peak at 0.4 eV. The intraband response of conducting carriers is different from that of a simple Drude metal. A peak at low but finite frequency is observed, which shifts to higher frequencies with increasing temperature, even though the dc resistivity is metallic. We discussed the origin of the interband transitions and the low-frequency charge dynamics based on the results of band structure calculations and quasiparticle behavior observed in ARPES experiment.

description: Phonon transport across a silicon/vacuum-gap/silicon structure is modeled using lattice dynamics calculations and Landauer theory. The phonons transmit thermal energy across the vacuum gap via atomic interactions between the leads. Because the incident phonons do not encounter a classically impenetrable potential barrier, this mechanism is not a tunneling phenomenon. While some incident phonons transmit across the vacuum gap and remain in their original mode, many are annihilated and excite different modes. We show that the heat flux due to phonon transport can be 4 orders of magnitude larger than that due to photon transport predicted from near-field radiation theory.

description: No abstracts are to be cited without prior reference to the author.Decrease of the catch ability and fishing mortality in gillnets in conditions of long-range lower water temperatures cause underestimation of the population size, while catch ability dynamics of traps affects the stock abundance indices in opposite direction.

We find a small mass shift for the D-meson in this hot and dense medium while the spectral density develops a sizeable width. The reduced attraction felt by the D-meson in hot and dense matter together with the large width observed have important consequences for the D-meson production in the future CBM experiment at FAIR.

description: Movements of individual domain walls in a ferromagnetic garnet were studied with angstrom resolution. The measurements reveal that domain walls can be locked between adjacent crystallographic planes and propagate by distinct steps matching the lattice periodicity. Domain walls are found to be weakly mobile within valleys of the atomic washboard but become unexpectedly flexible on Peierls ridges, where they can be kept in a bi-stable state by ac magnetic field. We describe the latter observation in terms of a single magnetic kink propagating along a domain wall.

description: No abstracts are to be cited without prior reference to the author.This study proposes a methodology producing rules to understand kelp forest distribution according to environmental parameters and hence, predictive maps. Key parameters used to predict the presence of kelp forest are grouped into three themes concerned with 1/ the nature of the substrate, 2/ the influence of the local environment: topology and hydrodynamics, and 3/ the nature of the water body overlying the substrate: turbidity, expressed by the attenuation coefficient of the photosynthetically available radiation, the KPAR, calculated from SeaWiFS radiances, and temperature, expressed as Sea Surface Temperature SST, from AVHRR radiances. Kelp forest observations used to build and to validate the predictive model are derived from acoustic detection of seaweeds at 10 sites along the Brittany coast. Kelp forest distribution on rock substrata remains stable in shallow water until a first depth limit, named H1. Local topology, expressed using the BPI (Bathymetric Position Index), explains the variability of kelp distribution above H1, where light and temperature are sufficient. Below depth H1, the percentage of presence decreases until the disappearance of kelp forest at a depth limit named H2. The variability of depths H1 and H2 over sites is mainly explained by the turbidity, or by the temperature. Indeed, an increase in KPAR is responsible for raising the depths H1 and H2, whereas an increase in SST explains the deeper depth limit. The maximum current velocity during the mean spring tide, from hydrodynamic model simulations, also explains kelp distribution along the Brittany coast. For a constant turbidity, a drop in the depth limit H2 occurs in direct ratio with the power 1.5 of the velocity. This latter parameter expresses the drag pressure in relation to the flexibility of algae. Using these relationships, predictive maps are produced and validated.

description: No abstracts are to be cited without prior reference to the author.Lepeophtheirus salmonis is a naturally occurring parasite on wild salmonids. Infestations of this sea louse pose a major economic burden to the Atlantic salmon aquaculture industry and may be linked to the decline of wild salmonid populations. Coupled models of surface circulation and louse biology have been used to understand the dispersion of planktonic larval lice from a point source, such as a fish farm. We have developed a sea lice dispersion model for Loch Torridon, a fjordictype sea loch on the west coast of Scotland, using output from two different hydrodynamic models. Surface circulation within Loch Torridon shows significant deviation across-loch from expected estuarine transport due to the complex shoreline geometry and relatively low freshwater input. Validation of transport has been carried out with a combination of current meters and drifter studies, in order to ensure transport patterns within the loch are represented. Simulated dispersal patterns of viable sea lice demonstrate a high dependence on wind and freshwater forcing, such that validation must be carried out under a range of environmental conditions. Further, complex coastlines of Scottish fjords mean that wall parameterizations can have significant influence on individual particle tracks. As this cannot be validated using drifter studies, a numerical exploration of the impact of varying wall parameterizations is undertaken.

description: Abstract: "We introduce a methodology for concurrent design that considers the allocation of tolerances and manufacturing processes for minimum cost. Cost is approximated as a hyperbolic function over tolerance, and worst-case stack-up tolerance is assumed. Two simulated annealing techniques are introduced to solve the optimization problem. The first assumes independent, unordered, manufacturing processes and usesa Monte-Carlo simulation; the second assumes well known individual process cost functions which can be manipulated to create a single continuous function of cost versus tolerance with discontinuous derivatives solved with a continuous simulated annealing algorithm. An example utilizing a system of friction wheels over the manufacturing processes of turning, grinding, and saw cutting bar stock demonstrates excellent results."

This transformation allows us to introduce the parallel transport of the operators along the RG trajectory. The connection on this one-dimensional manifold governs the scale evolution of the operator mixing. It is shown that the solution of the eigenvalue problem of the connection gives the various scaling regimes and the relevant operators there. The relation to perturbative renormalization is also discussed in the framework of the $ϕ^3$ theory in dimension $d=6$.

description: No abstracts are to be cited without prior reference to the author.We have developed an 11 compartment nutrient-phytoplankton-zooplankton (NPZ) model for the Gulf of Alaska (GOA). The objective of this modeling work is to understand how climate change will affect biological production in this region. This model is embedded within the Regional Ocean Modeling System (ROMS) circulation model, here implemented for the GOA. A persistent problem in this type of biophysical NPZ model is obtaining the proper timing of the spring bloom. The onset of the bloom is extremely sensitive to the onset of stratification in the water column after winter mixing. We have found that in our model the bloom occurs in March or early April, which is too early by about a month. This was traced to excessive vertical stratification of salinity in the physical model, especially in the spring. We have focused on several processes which contribute to this discrepancy: mixing of coastal runoff with oceanic waters in small estuaries (not resolved in our circulation model); and near-surface mixing of shelf waters, driven by breaking surface waves, internal tides, and other processes not resolved (and/or incorrectly parameterized) by our model. In this presentation, we illustrate this issue and the effects on the modeled biological system, and discuss methods to address the problem. We illustrate the use of a stability index to assess the salinity stratification in models and data, and discuss the sensitivity of the biology to this index. We explore the nonlinear sensitivity of the circulation and NPZ models to alternate mixing parameterizations, intended to better capture the unresolved physics of this region.

description: A fast, parallel algorithm for distant-dependent calculation and simulation of crystal properties is presented along with speedup results and methods of application. An illustrative example is used to compute the Lennard-Jones lattice constants up to 32 significant figures for $4\leq p\leq30$ in the simple cubic, face-centered cubic, body-centered cubic, hexagonal-close-pack, and diamond lattices. In most cases, the known precision of these constants is more than doubled, and in some cases, corrected from previously published figures. The tools and strategies to make this computation possible are detailed along with application to other potentials, including those that model defects.

description: Spin-orbit coupling plays an important role in determining the properties of solids, and is crucial for spintronics device applications. Conventional spin-orbit coupling arises microscopically from relativistic effects described by the Dirac equation, and is described as a single particle band effect. In this work, we propose a new mechanism in which spin-orbit coupling can be generated dynamically in strongly correlated, non-relativistic systems as the result of fermi surface instabilities in higher angular momentum channels. Various known forms of spin-orbit couplings can emerge in these new phases, and their magnitudes can be continuously tuned by temperature or other quantum parameters.

description: Electrified vehicles, including plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs), have the potential to reduce greenhouse gas (GHG) emissions from personal transportation by shifting energy demand from gasoline to electricity. GHG reduction potential depends on vehicle design, adoption, driving and charging patterns, charging infrastructure, and electricity generation mix. We construct an optimization model to study these factors by determining optimal design of conventional vehicles (CVs), hybrid electric vehicles (HEVs), PHEVs, and BEVs and optimal allocation of vehicle designs and charging infrastructure in the fleet for minimum lifecycle GHG emissions over a range of scenarios. We focus on vehicles with similar size and acceleration to a Toyota Prius under urban EPA driving conditions. We find that under today’s U.S. average grid mix, the vehicle fleet allocated for minimum GHG emissions includes HEVs and PHEVs with ~30 miles (48 km) of electric range. Allocating only CVs, HEVs, PHEVs, or BEVs will produce 86%, 1%, 0%, or 13+% more life cycle GHG emissions, respectively. Unlike BEVs, PHEVs do consume some gasoline; however, PHEVs can power a large portion of vehicle miles on electrical energy while accommodating infrequent long trips without need for a large battery pack, with its corresponding production and weight implications. Availability of workplace charging for 90% of vehicles optimistically reduces optimized GHG emissions by 0.5%. Under decarbonized grid scenarios, larger battery packs are more competitive and reduce life cycle GHG emissions significantly. Future work will relax modeling assumptions and address life cycle cost and cost-effectiveness of GHG reductions.
On the improvement of SPT2 approach in the theory of a hard sphere fluid in disordered porous media

description: The SPT2 approach is based on the scaled particle theory and developed for the description of thermodynamic properties of hard sphere (HS) fluids in disordered porous media. Using this approach a porous medium is modelled as a quenched matrix of hard spheres (HS) or overlapping hard spheres (OHS). A hard sphere fluid immersed in a matrix can move in a void between matrix particles. A number of approximations were previously proposed within the SPT2 approach. Among these approximations, the SPT2b1 has been considered as the most successful and accurate one in a large range of fluid densities and for different matrix parameters. However, at high densities, it can lack accuracy, since it does not take into account that the maximum packing fraction of a HS fluid in a matrix is limited, not by the geometrical porosity of a matrix $ϕ_{0}$ and the probe particle porosity $ϕ$, but by another type of porosity $ϕ^{*}$ introduced in our previous studies. The porosity $ϕ^{*}$ is related to the maximal adsorption capacity of a matrix and it is lower than $ϕ_{0}$ and larger than $ϕ$. This can be crucial for a fluid in matrices of low porosities and at high fluid density, especially in the region near close-packing conditions. Therefore, the approximations SPT2b2 and SPT2b3 taking into account this feature were suggested, although they still needed a correction because of their poor accuracy. In the present study, we improved the versions of these approximations, named as SPT2b2$^*$ and SPT2b3$^*$. We compare these different approximations with the results of computer simulations performed in the Monte Carlo grand-canonical ensemble. We test the SPT2 approach both for the one- and three-dimensional cases. We show that the SPT2b3$^*$ provides a very good description of the chemical potential of a confined fluid, which is better than others.

description: Sexual selection theory is a robust and dynamic field within evolutionary biology, yet despite decades of research, remarkably little is known of the mechanistic bases of mate choice and male competition. Because many aspects of sexual selection involve dynamic movements, and are physically challenging, the limits of sexual selection may be defined by key functional and physiological variables (i.e. the ‘functional approach’). We advocate the functional approach for providing mechanistic resolution on the adaptive basis of sexual structures and signals, the nature of mate choice and how males compete, among other issues. An overview of recent work, highlighted in this special issue, shows that many features of sexual selection, including the outcome of male fights, the morphology and design of sexual signals, and the nature of mate choice, all appear to be dictated in large part by functional and physiological parameters. We argue that the functional approach provides a potent tool for resolving several unresolved issues in sexual selection theory, particularly the nature of male quality, the handicap and indicator models of sexual selection, and the basis of mate choice.
Once-per-step control of ankle-foot prosthesis push-off work reduces effort associated with balance during walking

description: Individuals with below-knee amputation have more difficulty balancing during walking, yet few studies have explored balance enhancement through active prosthesis control. We previously used a dynamical model to show that prosthetic ankle push-off work affects both sagittal and frontal plane dynamics, and that appropriate step-by-step control of push-off work can improve stability. We hypothesized that this approach could be applied to a robotic prosthesis to partially fulfill the active balance requirements of human walking, thereby reducing balance-related activity and associated effort for the person using the device. Methods We conducted experiments on human participants (N = 10) with simulated amputation. Prosthetic ankle push-off work was varied on each step in ways expected to either stabilize, destabilize or have no effect on balance. Average ankle push-off work, known to affect effort, was kept constant across conditions. Stabilizing controllers commanded more push-off work on steps when the mediolateral velocity of the center of mass was lower than usual at the moment of contralateral heel strike. Destabilizing controllers enforced the opposite relationship, while a neutral controller maintained constant push-off work regardless of body state. A random disturbance to landing foot angle and a cognitive distraction task were applied, further challenging participants’ balance. We measured metabolic rate, foot placement kinematics, center of pressure kinematics, distraction task performance, and user preference in each condition. We expected the stabilizing controller to reduce active control of balance and balance-related effort for the user, improving user preference. Results The best stabilizing controller lowered metabolic rate by 5.5% (p = 0.003) and 8.5% (p = 0.02), and step width variability by 10.0% (p = 0.009) and 10.7% (p = 0.03) compared to conditions with no control and destabilizing control, respectively. Participants tended to prefer stabilizing controllers. These effects were not due to differences in average push-off work, which was unchanged across conditions, or to average gait mechanics, which were also unchanged. Instead, benefits were derived from step-by-step adjustments to prosthesis behavior in response to variations in mediolateral velocity at heel strike. Conclusions Once-per-step control of prosthetic ankle push-off work can reduce both active control of foot placement and balance-related metabolic energy use during walking.

description: No abstracts are to be cited without prior reference to the author.The most important gadoid fish stocks of the Barents Sea spawn along the coast of Norway. The eggs, larvae and juveniles are transported northwards with the oceanic coastal currents from the spawning grounds towards their nursery and feeding areas in the Barents Sea. In this work, we present a conceptual model of the vertical dynamics of 0-group during the transport and settlement phase. Field observations of the vertical distribution and behaviour of 0-group fish recorded by a stationary acoustic system are compared to the conceptual model to validate critical assumptions. They also serve as an example of some critical observations needed to improve hydrodynamic modelling of the transport. We used two different vertical distribution algorithms for particles representing juvenile fish in a Lagrangian particletracking model. One is based on the behaviour described in the conceptual model and the other assumes random vertical distribution at a fixed depth range throughout the whole period. The distribution predicted from the vertical behaviour algorithms fits best to observations from surveys. Based on this experience we propose an observation program for collecting the needed observations to obtain a more realistic recruitment prediction model.
