In this study, daily maps of snow cover distribution and sea ice extent produced by NOAA’s interactive multisensor snow and ice mapping system (IMS) were validated using in situ snow depth data from observing stations obtained from NOAA’s National Climatic Data Center (NCDC) for calendar years 2006 to 2010. IMS provides daily maps of snow and sea ice extent within the Northern Hemisphere using ...

unways" are not just for airports. At Long Beach Memorial Medical Center (LBMMC) and its subsidiary. Miller Children's Hospital, both of which occupy the same campus in Long Beach, CA, keeping the "runways" clear for patient admissions has increased volumes by more than 160 patients per day and net income by 700 percent. Senior managers, who arc these hospitals' chief "traffic controllers," dev...

We examine the presence of general (nonlinear) time-independent Lie point symmetries in dynamical systems, and especially in bifurcation problems. A crucial result is that center manifolds are invariant under these symmetries: this fact, which may be also useful for explicitly nding the center manifold, implies that Lie point symmetries are inherited by the "reduced" bifurcation equation (a res...

We characterize the structure of a seven-dimensional Lie algebra with non-trivial center endowed closed G$_2$-structure. Using this result, we classify all unimodular algebras admitting G$_2$-structures, up to isomorphism, and show that six them arise as contactization symplectic algebra. Finally, prove every semi-algebraic soliton on must be expanding, determine dimension at least two admit so...

We prove that, given a nontrivial Boolean algebra B, a compact convex set S and a groupG, there is an orthomodular latticeL with the center isomorphic toB, the automorphism group isomorphic to G, and the state space affinely homeomorphic to S. Moreover, given an orthomodular lattice J admitting at least one state, L can be chosen such that J is its subalgebra. Mathematics Subject Classification...

In this paper we study the number of ergodic measures maximal entropy for partially hyperbolic diffeomorphisms defined on 3-torus with compact center leaves. Assuming existence a periodic leaf Morse–Smale dynamics prove sharp upper bound in terms sources and sinks dynamics. A well-known class examples which our results apply are so called Kan-type admitting physical intermingled basins.

We consider a class of deterministic mean field games, where the state associated with each player evolves according to an ODE which is linear w.r.t. control. Existence, uniqueness, and stability solutions are studied from point view generic theory. Within suitable topological space dynamics cost functionals, we prove that, for “nearly all” games (in Baire category sense) best reply map single-...
