UNLABELLED It is unclear whether the maximum acceptable weight of lift (MAWL), a common psychophysical method, reflects joint kinetics when different lifting techniques are employed. In a within-participants study (n = 12), participants performed three lifting techniques--free style, stoop and squat lifting from knee to waist level--using the same dynamic functional capacity evaluation lifting ...

This paper is concerned with the controllability of quantum systems in the case where the standard dipolar approximation, involving the permanent dipole moment of the system, has to be corrected by a so-called polarizability term, involving the field induced dipole moment. Sufficient conditions for controllability between eigenstates of the free Hamiltonian are derived and control laws are expl...

In this note we prove a generalization of the flat extension theorem of Curto and Fialkow (Memoirs of the American Mathematical Society, vol. 119. American Mathematical Society, Providence, 1996) for truncated moment matrices. It applies to moment matrices indexed by an arbitrary set of monomials and its border, assuming that this set is connected to 1. When formulated in a basis-free setting, ...

the question of whether architectural creativity is more of an artistic or engineering nature is one with a long history but also one with no conclusive answer. the art camp would argue that technology should be treated as a means towards and end, and that technology alone cannot give meaning to our lives. the engineering camp on the other hand would argue that good problem-solving results in b...

Four thyroid function indices were determined in the sera of 181 patients: total thyroxine (T-4), the triiodothyronine resin uptake (T-3 B.C.-index), the free thyroxine (T-4) index, and the effective thyroxine ratio (E.T.R.).A statistically significant correlation between the free T-4 index and E.T.R. could be established though this correlation seemed to be worse than could be expected from th...

Theoretical studies of localization, anomalous diffusion and ergodicity breaking require solving the electronic structure of disordered systems. We use free probability to approximate the ensemble-averaged density of states without exact diagonalization. We present an error analysis that quantifies the accuracy using a generalized moment expansion, allowing us to distinguish between different a...

The magnetic susceptibilities of the compounds (Dy,YI_.)ZM~207 for x = 1.0, 0.8, 0.6, 0.4 and 0.2 have been measured in the temperature range 6OC-4.2 K to check whether any magneticordering is found at low temperaturesand toseparate the contributions from D?' and Mod+ to the susceptibility in the paramagnetic region. The effective magnetic moment of Dy3' was found to be less than that of the fr...

In this study, the experimental and the simulation results for a planar free link impacting a granular medium are analyzed. The resistance force of the granular medium on the body from the moment of the impact until the body stops is very important. Horizontal and vertical static resistance forces developed by theoretical and empirical approaches are considered. The penetrating depth of the imp...

Mixtures of Lennard-Jones and Stockmayer molecules provide a convenient model system which can be used to study the effects of composition and polarity in polar/non-polar mixtures. The structure and phase behaviour of such mixtures are currently topics of great interest Eli. Since the Stockmayer potential, qSs, is obtained from the usual Lennard-Jones potential, ~buj, by the sole addition of a ...

When choosing actions, we can act decisively, vacillate, or suffer momentary indecision. Studying how individual decisions unfold requires moment-by-moment readouts of brain state. Here we provide such a view from dorsal premotor and primary motor cortex. Two monkeys performed a novel decision task while we recorded from many neurons simultaneously. We found that a decoder trained using 'forced...
