"... We have considered two representations of a longitudinal section of the shoot apex: a regular grid and a cellular template based on a real meristem section. Depending on the case, cells are represented as square or arbitrary polygons, which share with the neighboring cells the edges that represent t ..."

Probabilistic independence networks for hidden Markov probability models
, 1996
"... Graphical techniques for modeling the dependencies of random variables have been explored in a variety of different areas including statistics, statistical physics, artificial intelligence, speech recognition, image processing, and genetics. Formalisms for manipulating these models have been develop ..."

that the wellknown forwardbackward (FB) and Viterbi algorithms for HMMs are special cases of more general inference algorithms for arbitrary PINs. Furthermore, the existence of inference and estimation algorithms for more general graphical models provides a set of analysis tools for HMM practitioners who
Pinning of polymers and interfaces by random potentials
, 2005
"... We consider a polymer, with monomer locations modeled by the trajectory of a Markov chain, in the presence of a potential that interacts with the polymer when it visits a particular site 0. Disorder is introduced by, for example, having the interaction vary from one monomer to another, as a constant ..."

occurs at sufficiently low temperatures. If the excursion length distribution has polynomial tails and the interaction does not have a finite exponential moment, then pinning occurs for all u∈R at arbitrary temperature. Our results apply to other mathematically similar situations as well, such as a
FreeForm Shape Design Using Triangulated Surfaces
, 1994
"... We present an approach to modeling with truly mutable yet completely controllable freeform surfaces of arbitrary topology. Surfaces may be pinned down at points and along curves, cut up and smoothly welded back together, and faired and reshaped in the large. This style of control is formulated as a ..."

Quenched and annealed critical points in polymer pinning models
"... Abstract. We consider a polymer with configuration modeled by the path of a Markov chain, interacting with a potential u+Vn which the chain encounters when it visits a special state 0 at time n. The disorder (Vn) is a fixed realization of an i.i.d. sequence. The polymer is pinned, i.e. the chain spe ..."

Pinning of magnetic vortices by an external potential
, 2005
"... The existence and uniqueness of vortex solutions is proved for Ginzburg–Landau equations with external potentials in R². These equations describe the equilibrium states of superconductors and the stationary states of the U(1)Higgs model of particle physics. In the former case, the external potentia ..."

potentials are due to impurities and defects. Without the external potentials, the equations are translationally (as well as gauge) invariant, and they have gauge equivalent families of vortex (equivariant) solutions called magnetic or Abrikosov vortices, centered at arbitrary points of R². For smooth
Statistical Studies of the Anisotropy of the Pinning Mechanism in YBaCuO Films Deposited on Polycrystalline YSZ Substrates

"... Abstract. We have studied the IV characteristics and the behaviour of the critical current density of Y B a 2 C ~ 3 0 7. ~ films, prepared by sputtering, at different values of applied magnetic field and of temperature. The superconductor was deposited onto polycrystalline Zr02 (8 mol % Y2O3). The ..."

Compact CCASecure Encryption for Messages of Arbitrary Length

Lower Bounds for Pinning Lines by Balls (Extended Abstract)
, 2009
"... It is known that if n ≥ 2d pairwise disjoint balls in R d have a unique line ℓ intersecting them in a given order ≺, one can always remove a ball so that ℓ remains the only line intersecting the balls in the order induced by ≺. We show that the constant 2d is best possible, in any dimension, and der ..."
