The intelligence cycle is dead, long live the intelligence cycle: Rethinking intelligence fundamentals for a new intelligence doctrine
In the spring of 2009 the UK Ministry of Defence elected to undertake a review of the existing military Joint Intelligence Doctrine. The existing doctrine, Joint Warfare Doctrine 2-00 (JWP 2-00) Intelligence Support to Joint Operations had been promulgated in 2003 largely on the basis of coalition-oriented expeditionary and peace support operations in the Balkans, Middle East and Afghanistan. This had replaced an earlier, first edition of JWP 2-00 issued in 1999
Nondiffusive suprathermal ion transport in simple magnetized toroidal plasmas
We investigate suprathermal ion dynamics in simple magnetized toroidal
plasmas in the pres- ence of electrostatic turbulence driven by the ideal
interchange instability. Turbulent fields from fluid simulations are used in
the non-relativistic equation of ion motion to compute suprathermal tracer ion
trajectories. Suprathermal ion dispersion starts with a brief ballistic phase,
during which particles do not interact with the plasma, followed by a
turbulence interaction phase. In this one simple system, we observe the entire
spectrum of suprathermal ion dynamics, from subdiffusion to superdiffusion,
depending on beam energy and turbulence amplitude. We estimate the duration of
the ballistic phase and identify basic mechanisms during the interaction phase
that determine the character of suprathermal ion dispersion upon the beam
energy and turbulence fluctuation amplitude.Comment: 5 pages, 3 figures, accepted in PR
Did Earth-approaching asteroids 3551, 3908, or 4055 produce meteorites?
Orbital integrations show that Amor asteroid 3908 could have ejected one out of four plausible groups of meteorite producing fireballs during a collision in the asteroid belt. It was suggested by others that such a collision may also have split asteroids 3551 and 3908. A member of this group of fireballs is listed as one of the better possibilities for recovery
Dynamics of soliton-like solutions for slowly varying, generalized gKdV equations: refraction vs. reflection
In this work we continue the description of soliton-like solutions of some
slowly varying, subcritical gKdV equations.
In this opportunity we describe, almost completely, the allowed behaviors:
either the soliton is refracted, or it is reflected by the potential, depending
on its initial energy. This last result describes a new type of soliton-like
solution for gKdV equations, also present in the NLS case.
Moreover, we prove that the solution is not pure at infinity, unlike the
standard gKdV soliton.Comment: 51 pages, submitte
Long time motion of NLS solitary waves in a confining potential
We study the motion of solitary-wave solutions of a family of focusing
generalized nonlinear Schroedinger equations with a confining, slowly varying
external potential, . A Lyapunov-Schmidt decomposition of the solution
combined with energy estimates allows us to control the motion of the solitary
wave over a long, but finite, time interval. We show that the center of mass of
the solitary wave follows a trajectory close to that of a Newtonian point
particle in the external potential over a long time interval.Comment: 42 pages, 2 figure

The Madden–Julian oscillation wind-convection coupling and the role of moisture processes in the MM5 model
The Madden–Julian oscillation (MJO) produced by a mesoscale model is investigated using standardized statistical diagnostics. Results show that upper- and lower-level zonal winds display the correct MJO structure, phase speed (8 m s[superscript −1]) and space–time power spectrum. However, the simulated free atmosphere moisture, outgoing longwave radiation and precipitation do not exhibit any clear MJO signal. Yet, the boundary layer moisture, moist static energy and atmospheric instability, measured using a moist static energy instability index, have clear MJO signals. A significant finding is the ability of the model to simulate a realistic MJO phase speed in the winds without reproducing the MJO wind-convection coupling or a realistic propagation in the free atmosphere water vapor. This study suggests that the convergence of boundary layer moisture and the discharge and recharge of the moist static energy and atmospheric instability may be responsible for controlling the speed of propagation of the MJO circulation.National Science Foundation (U.S.) (Grant ATM0733698
