Rotational alignment of the femoral component during TKA is critical. Here we propose a technique using navigation of the femoral trochlea to determine the rotation of the femoral component. The rotation is considered "ideal" when the component position leads to the arthroplasty trochlea being perfectly superimposed over the native trochlea. Thus the arthroplasty trochlea will be aligned on the...

UVES and HIRES high-resolution spectra of comet 9P/Tempel 1 are used to investigate the impact and rotational light curves of various species with a view toward building a simple model of the distribution and activity of the sources. The emission by OH, NH, CN, C3, CH, C2, NH2 and O I, are analyzed, as well as the light scattered by the dust. It is found that a simple model reproduces fairly we...

The direction of the bootstrap current is inverted in the outward shifted plasmas of the Large Helical Device (LHD). In order to verify the reliability of the theoretical models of the bootstrap current in helical plasmas, the rotational transform profiles are observed by the Motional Stark Effect measurement in the bootstrap current carrying plasmas of the LHD, and they are compared with the n...

In this paper, we present a method to model and control the interface electronics in order to obtain maximum power transfer from a rotational energy harvester. A state-space representation of a boost converter (with component parasitics) was derived and embedded in a control loop that performs input impedance matching to the armature resistance of the rotational harvester. Root locus techniques...

version lines of ammonia (NH 3) have been detected toward the nuclear 40 ′′ sized bar of the nearby spiral galaxy Maffei 2. The relative intensities of the ammonia lines are characterized by a rotational temperature of 85 K. This is higher than rotational temperatures measured toward IC 342 and most Galactic Center clouds, implying kinetic temperatures > ∼ 100 K. Since the kinetic temperature o...

We describe measurements of the rotational component of teleseismic surface waves using an inertial high-precision ground-rotation sensor installed at the Laser Interferometer Gravitational-Wave Observatory (LIGO) Hanford Observatory (LHO). The sensor has a noise floor of 0:4 nrad= Hz p at 50 mHz and a translational coupling of less than 1 μrad=m enabling translation-free measurement of small r...

We report a novel phenomenon of chiral selection in self-assembled condensates of achiral amphiphiles. The handedness of chiral textures, reproducing the collective rotational component of the molecular orientation inside submillimeter circular domains, is correlated with the sign of a vortical stirring in the aqueous subphase. We propose an explanation based on the distinctive kinetics of topo...

In this paper, we present and demonstrate a rotational energy harvester with a component-optimised maximum power point tracking (MPPT) circuit for adaptive power conversion. An AM-transmitter and receiver was used to instrument the harvester during operation. Experimental results on the effects of current limiting the harvester and the end-to-end efficiency of the MPPT circuit are shown. Finall...

We study the one component Φ 4 model for four different lattice actions in the Gaussian limit and for the Ising model in the broken phase. Emphasis is put on the euclidean invariance properties of the boson propagator. A measure of the violation of rotational symmetry serves as a tool to compare the regularization dependence of the triviality bound. * Supported by Fonds zur Förderung der Wissen...

Analysis of the rotational mobility of spin-labeled bovine heart cytochrome c oxidase by saturation transfer electron paramagnetic resonance(ST-EPR) has recently demonstrated that this enzymic complex can be obtained as an aggregate of individual protein molecules which display little or no rotational mobility on the submillisecond time scale (1). Aggregation appears to occur as a result of pro...
