On an EM-based closed-form solution for 2 parameter IRT models
Stefano Noventa, Roberto Faleh, Augustin Kelava
It is a well-known issue that in Item Response Theory models there is no closed-form for the maximum likelihood estimators of the item parameters. Parameter estimation is therefore…
ProDMPs: A Unified Perspective on Dynamic and Probabilistic Movement Primitives
Ge Li, Zeqi Jin, Michael Volpp +3
Movement Primitives (MPs) are a well-known concept to represent and generate modular trajectories. MPs can be broadly categorized into two types: (a) dynamics-based approaches that…
Variability in high-mass X-ray binaries
F. Fuerst, P. Kretschmar, V. Grinberg +5
Strongly magnetized, accreting neutron stars show periodic and aperiodic variability over a wide range of time scales. By obtaining spectral and timing information on these differe…
Hyperflares of SGRs as an engine for millisecond extragalactic radio bursts
S. B. Popov, K. A. Postnov
We propose that the strong millisecond extragalactic radio burst (mERB) discovered by Lorimer et al. (2007) may be related to a hyperflare from an extragalactic soft gamma-ray repe…
Anisotropic flow in Pb+Pb collisions at LHC from the quark gluon string model with parton rearrangement
J. Bleibel, G. Burau, C. Fuchs
We present predictions for the pseudorapidity dependence of the azimuthal anisotropy parameters v_1 and v_2 of baryons and inclusive charged hadrons in Pb+Pb collisions at a LHC en…
On the evolution of eccentric and inclined protoplanets embedded in protoplanetary disks
Paul Cresswell, Gerben Dirksen, Willy Kley +1
Young planets embedded in their protoplanetary disk interact gravitationally with it leading to energy and angular momentum exchange. This interaction determines the evolution of t…
