Accurate Force/Moment (F/M) measurements are required in many applications, and multi-axis F/M sensors have been utilized a wide variety of robotic systems since 1970s. A multi-axis F/M sensor is capable of measuring multiple components of force terms along x-, y-, z-axis (Fx, Fy, Fz), and the moments terms about x-, y- and z-axis (Mx, My and Mz) simultaneously. In this manuscript, we describe ...

We examined the role of gaze in a matching task, where subjects had to reproduce the position of remembered visual target with the tip of the index finger. For brevity, we will refer to this task as pointing. Subjects were tested in three visual feedback conditions: complete darkness (DARK), complete darkness with visual feedback of the finger position (FINGER), and with vision of a well-define...

The purpose of this study is to establish Liouville-type results for a three-dimensional incompressible, unsteady flow described by the Eyring–Powell fluid equations. studied in plane ?p while it moves along z-axis. Therefore main functions analyze are given u(x,y,z,t) and v(x,y,z,t), belonging ?p. obtained globally bounded initial data as well their corresponding derivatives, variations veloci...

This review focuses on the radiosensitization strategies that use high-Z nanoparticles. It does not establish an exhaustive list of the works in this field but rather propose constructive criticisms pointing out critical factors that could improve the nano-radiation therapy. Whereas most reviews show the chemists and/or biologists points of view, the present analysis is also seen through the pr...

The orbital structure of triaxial models with weak central density cusps, ρ ∝ r −γ , γ < 1, is investigated. The stability of the x-(long-) axis orbit – and hence the existence of box orbits – depends sensitively on γ; the range of model shapes for which the x-axis orbit is stable becomes progressively smaller as γ approaches one. The banana and fish boxlets in the x − z (long axis–short axis) ...

Abstract. Air-core magnetotorquer-only attitude control system (ACS) for the low-cost, spin-stabilized ITASAT satellite is here described. ITASAT’s ACS has been tested by simulation with synthetic measurement data. The proposed closedloop ACS system is based on 3-axis attitude and angular rate estimates provided by an extended Kalman filter processing vector measurements from a Sun sensor and a...

Let F and G denote two closed convex curves in the (X, Z)-plane and in the (Y, Z)-plane, correspondingly, that are symmetric about the Z-axis and cross at two points. Let S denote the solid that results from wrapping (X, Y )parallel ellipses around F and G. Surprisingly, S need not be convex (though all intersections with planes containing the Z-axis are!). We analyze under which condition the ...

Downbeat nystagmus (DBN) observed in head-hanging positions, may be of central or peripheral origin. Central DBN positions is mostly due to a disorder the vestibulo-cerebellum, whereas usually attributed canalolithiasis an anterior semicircular canal. Here, we describe atypical case patient who, after head trauma, experienced severe and stereotypic vertigo attacks being placed various positions...

“We thank Ben Cooper for helpful discussions, Ritva Syrjänen for pointing out useful references on the seasonality of colonization, Marc Lipsitch for advice in parametrizing the effects of previous exposures in the model and Dan Weinberger on sharing the point estimates on the Navajo colonization study, visualized in Fig. 1. E.N. and J.C. were funded by ERC grant no. 239784 and Academy of Finla...
