... the threedimensional analog of the four-dimensional Bondi-Metzner-Sachs (BMS) gauge [28,29], the general solution to the equations of motion can also be found in closed form ...
... SUMMARY: The aim of this study was to validate and correlate the two-dimensional (2D) with the three-dimensional (3D) measures of the upper airway assessment. Lateral cephalograms and cone beam CT of ...
... Dynamical systems theory has provided powerful tools to the Lagrangian study of turbulence and fluid motion, especially through the concepts of chaotic ad- vection, invariant manifolds and Lyapunov exponents. These ...
... Massive threedimensional gravity [1] has recently been under great scrutiny. It was shown in [2] that topologically massive gravity (TMG) with a cosmological constant (fine tuned with the Chern-Simons ...
... of threedimensional Lie bialgebras was considered in [2] (for k = R , C ), and more recently in [4] for k arbitrary, in geometric terms, involv- ing bilinear forms and Lagrangian ...
... As a nontrivial two-dimensional conformal field theory, Liouville theory is ubiquitous in theoretical physics (see e.g. [1–3] for reviews). In particular, in the context of three- dimensional ...
... The aim of this paper is to demonstrate within a simple class of models, namely topo- logical models of Chern-Simons type which we refer to as fractional-spin gravities, how standard tensorial higher-spin gravities can ...
... Higher spin gravity [1–3] has recently motivated a flurry of activity. In the case of d ≥ 4 dimensions, the consistency of the theory necessarily requires the presence of a negative cosmological constant, which naturally ...
... Interestingly, King Charles II’s probate list of assets makes mention of a huge mirror (3.5 × 2 varas, i.e. 2.9 × 1.7 m) hanging in the King’s bedchamber at the time of his death [26]. In the royal painters’ studio, ...
... Fasting and postprandial gallbladder volumes were measured by real-time 2D ultrasonography (3.5 MHz con- vex transducer, Pie Medical Scanner 250, Pie Medical, Maastricht, The Netherlands) using the sum-of-cylinders ...
... Feature detectors have long been one of the touchstones of image processing. Most vision tasks are entirely dependent on the accurate determination of fiducial marks on images, which ultimately led to a quest for methods ...
... with three ground states is superconductivity at high temperatures where a triplet instead of a singlet state minimizes the energy, which requires the extension of the Cooper-pairing mechanism (see ...

... The three-dimensional reconstruction of an object’s surface from stereo pairs of images is a classical problem in computer vision (see, for example [19], [13], [18], [26]), and it is still an extremely ...
... Therefore, three models have been built for CNA, one, in which all the containment is represented in a unique subdivided control volume, and two MZM with different mesh ...
