The human heart contracts and relaxes approximately once each second. This isa complex process where different parts of the cardiac tissue contract and relax atdifferent times and at different rates. The accurate evaluation of this deformation withultrasound requires the use of a high frame rate. The frame rate of a conventionalultrasound image is limited by the round trip propa...

It is easier to find a tilted bar among vertical bars than vice-versa, but this asymmetry can be abolished or reversed by surrounding the bars with a tilted frame. The frame effect is important because it challenges bottom-up models of saliency. We conducted two experiments to investigate the causes of this effect. In Experiment 1, we removed different components of a square frame, and conclude...

The historical origins of Fermi-Walker transport and Fermi coordinates and the construction of Fermi-Walker transported frames in black hole spacetimes are reviewed. For geodesics this transport reduces to parallel transport and these frames can be explicitly constructed using either Killing or Killing-Yano tensors, the latter route chosen by Marck. For accelerated or geodesic circular orbits i...

The axiomatic approach to parallel transport theory is partially discussed. Bijective correspondences between the sets of connections, (axiomatically defined) parallel transports and transports along paths satisfying some additional conditions are constructed. In particular, the equivalence between the concepts “connection” and “(axiomatically defined) parallel transport” is established. Some r...

A bstract We investigate both from a qualitative as well quantitative perspective the emergence of chaos in QCD confining string magnetic field holographic view-point. use an earlier developed bottom-up solution Einstein-Maxwell-Dilaton action that mimics and its thermodynamics quite well. Surprisingly, our predictions depend on used frame: tends to suppress perpendicular parallel directions re...

The authors report the case of a 28-year old male who presented with a compound diaphyseal fracture of the tibia, which was treated with intramedullary nailing. Postoperatively he required an extensive fasciotomy for an acute compartment syndrome. The fracture evolved towards post-traumatic osteomyelitis, growing methicillin-resistant Staphylococcus aureus (MRSA), combined with a large overlyin...

We investigate the scenario of using the Automatic Repeat reQuest (ARQ) retransmission scheme for two-way low bit-rate video communications over wireless Rayleigh fading channels. We show that during the retransmissions of error packets, due to the reduced channel throughput, the video encoder buffer may fill-up quickly and cause the TMN8 rate-control algorithm to significantly reduce the bits ...

The geometry of a smooth line is characterized locally by its curvature and torsion, or globally by its writhe. In many situations of physical interest the line is, however, not smooth so that the classical Frenet description of the geometry breaks down everywhere. One example is a thermalized stiff polymer such as DNA, where the shape of the molecule is the integral of a Brownian process. In s...

The Wasserstein distance on multivariate non-degenerate Gaussian densities is a Riemannian distance. After reviewing the properties of the distance and the metric geodesic, we derive an explicit form of the Riemannian metrics on positive-definite matrices and compute its tensor form with respect to the trace scalar product. The tensor is a matrix, which is the solution of a Lyapunov equation. W...

In today's 300mm wafer fabrication facilities, large parts of the lot processing are performed in cluster tools. Cluster tools are machines where a number of process chambers are attached to a main frame containing a transport robot. In contrast to traditional single process tools it is possible to load cluster tools with more than one lot, even with lots from different products. As a consequen...
