We demonstrate the existence of long-lived, large-amplitude eccentric modes in massive, annular particle disks in orbit about a central mass. The lopsided modes we have found precess slowly in the prograde direction at a rate which increases with disk mass and decreases with the amplitude of the distortion. The lopsidedness generally survives for as long as we run the calculations and may last ...

We present a method for identifying the coherent structures associated with individual Lagrangian flow trajectories even where only sparse particle trajectory data are available. The method, based on techniques in spectral graph theory, uses the Coherent Structure Coloring vector and associated eigenvectors to analyze the distance in higher-dimensional eigenspace between a selected reference tr...

In this report, we detail a novel approach to recover 3D hand pose from 2D images. To this end, we introduce a compact 3D hand model in a low dimension space where anatomy, kinematics and dynamics are implicitly inherited. The parameters of this model are recovered through a Bayesian inference approach. To this end, we propose an objective function which aims at separating the hand-skin charact...

The single-particle properties of $^{29}\mathrm{Mg}$ have been investigated via a measurement the $^{28}\mathrm{Mg}(d,p)^{29}\mathrm{Mg}$ reaction, in inverse kinematics, using ISOLDE Solenoidal Spectrometer. negative-parity intruder states from $fp$ shell identified and used to benchmark modern shell-model calculations. systematic data on centroids along $N=17$ isotones show good agreement wit...

Abstract In High Energy Physics experiments Particle Flow (PFlow) algorithms are designed to provide an optimal reconstruction of the nature and kinematic properties particles produced within detector acceptance during collisions. At heart PFlow is ability distinguish calorimeter energy deposits neutral from those charged particles, using complementary measurements particle tracking devices, a ...

With the compelling evidence for massive neutrinos from recent νoscillation experiments, one of the most fundamental tasks of particle physics over the next years will be the determination of the absolute mass scale of neutrinos, which has crucial implications for cosmology, astrophysics and particle physics. Neutrino oscillation experiments can measure squared mass differences but not masses. ...

The AdS3/CFT2 correspondence features massless non-relativistic modes on the string worldsheet in lightcone gauge. We study detail these excitations and highlight how they naturally split between chiral (left-moving) anti-chiral (right-moving) representations. In light of this we discuss constraints two-particle S matrix imposed by braiding physical unitarity, parity, time-reversal, crossing in...

We demonstrate the use of symbolic regression in deriving analytical formulas, which are needed at various stages a typical experimental analysis collider phenomenology. As first application, we consider kinematic variables like stransverse mass, ${M}_{T2}$, defined algorithmically through an optimization procedure and not terms formula. then train obtain correct expressions for all known speci...
