In the last 10 years, we have dramatically increased our knowledge on (epi)genetics, etiology, and dynamics of Follicular lymphoma (FL). that period, it has become widely accepted preclinical subclinical development phases FL, taking years from emergence a unique t(14;18)+ B cell in BM to detection symptomatic LN full its descendants aggregated FL follicles, involves multiple transits Mem-like ...

An important task in trajectory analysis is clustering. The results of a clustering are often summarized by a single representative trajectory and an associated size of each cluster. We study the problem of computing a suitable representative of a set of similar trajectories. To this end we define a central trajectory C , which consists of pieces of the input trajectories, switches from one ent...

First we show explicitly how uncertainty can arise in a trajectory representation. Then we show that the formal utilization of the WKB like hierarchy structure of dKdV in the description of (X,ψ) duality does not encounter norm constraints. 1. BACKGROUND In a previous paper [4] (working with stationary states and ψ satisfying the Schrödinger equation (SE) (A0) − (~2/2m)ψ′′+V ψ = Eψ) we suggeste...

Recently, a video representation based on dense trajectories has been shown to outperform other human action recognition methods on several benchmark datasets. The trajectories capture the motion characteristics of different objects, for example human bodies, in spatial and temporal dimensions. In dense trajectories, points are sampled at uniform intervals in space and time and then tracked usi...

In this paper, we present an OLAP framework for trajectories of moving objects. We introduce a new operator GROUP TRAJECTORIES for group-by operations on trajectories and present three implementation alternatives for computing groups of trajectories for group-by aggregation: group by overlap, group by intersection, and group by overlap and intersection. We also present an interactive OLAP envir...

In this paper, the acceleration of an electron in the interaction with a plasma wave and a magnetized ion-channel is analyzed. The electron dynamics is studied treated employing complete three-dimensional Lorentz force equations. A relativistic three dimensional single particle code is used to obtain the electron-trajectories. The results of numerical calculation show that the electrons can be ...

We investigate the use of shuffle on trajectories to model certain classes of languages arising in the theory of codes. In particular, for each finite set of sets of trajectories, which we call a hyperset of trajectories, we define a class of languages induced by that hyperset of trajectories. We investigate properties of hypersets of trajectories and the associated classes of languages, includ...

Although the foundations of the hydrodynamical formulation of quantum mechanics were laid over 50 years ago, it has only been within the past few years that viable computational implementations have been developed. One approach to solving the hydrodynamic equations uses quantum trajectories as the computational tool. The trajectory equations of motion are described and methods for implementatio...
