Centering: A Framework for Modeling the Local Coherence Of Discourse
 Computational Linguistics
, 1995
"... This paper concerns relationships among focus of attention, choice of referring expression, and perceived coherence of utterances within a discourse segment. It presents a framework and initial theory of centering intended to model the local component of attentional state. The paper examines intera ..."

Active Contours without Edges
, 2001
"... In this paper, we propose a new model for active contours to detect objects in a given image, based on techniques of curve evolution, MumfordShah functional for segmentation and level sets. Our model can detect objects whose boundaries are not necessarily defined by gradient. We minimize an energy ..."

On the Structure of Initial Segments of Models of Arithmetic
"... Abstract. For any countable nonstandard model M of a sufficiently strong fragment of arithmetic ~ and any nonstandard numbers a, C EM, MF C ~ a, there is a model K of T which agrees with M up to a and such that in K there is a proof of contradiction in T with Godel number ~ 2ac. lntroduction For any ..."

Abstract. For any countable nonstandard model M of a sufficiently strong fragment of arithmetic ~ and any nonstandard numbers a, C EM, MF C ~ a, there is a model K of T which agrees with M up to a and such that in K there is a proof of contradiction in T with Godel number ~ 2ac. lntroduction For any M a model of arithmetic and a EM, M r a will denote the structure with the universe {iEMIMFi~a}, and with operations inherited from M. Thus + and. are only partial functions in M r a. The general question that we study bere is this: For which functions f(x) the structure M ra uniquely determines the st,ructure Mr f(a)? "Determines " means "up to elementary equivalence " or equivaiently as all Mra are recursively saturated "up to isomorphism", It is easily seen that Mra determines Mrak, for any k<w. Paris and Dimitracopoulos [3J showed that M ra does not determineM r2G. Namely, they proveï that for any countable nonstandard model M of PA and any aEM nonstandard, there is K a model of PA such that aEK, Mra=Kra, but Mr22°$Kr22°. Thus either Mra does not determine Mr2G or Mr2G does not determine M r22O. Later Hájek [3J found ODe L1o formula 4>(x) such that for any aEM as above, there is K, a E K, K r a = Mr a and KF 4>(22°) and MF,4>(22°) or KF,4>(22°) and MF 4>(22°). He has also shown that for any a E M as above, there is K such that aEK, Mra=Kra and 224
ON CLONES OF INFINITARY ALGEBRAS AND THEIR INITIAL SEGMENTS
"... Abstract. We give the respective answers to the question of when the existence of all local clone isomorphisms implies the existence of a global clone isomorphism for term clones, polynomial clones and centralizer clones of universal algebras of an infinitary similarity type. 1. ..."

The small pyramidal neuron of the rat cerebral cortex: the axon hillock and initial segment
 J. Cell Biol
, 1968
"... The axon of the pyramidal neuron in the cerebral cortex arises either directly from the perikaryon or as a branch from a basal dendrite. When it arises from the perikaryon, an axon hillock is present. The hillock is a region in which there is a transition between the cytological features of the peri ..."

Thus, in the hillock there is a diminution in the number of ribosomes and a beginning of the fasciculation of microtubules that characterize the initial segment. Not all of the microtubules entering the hillock from the perikaryon continue
KOLMOGOROV COMPLEXITY OF INITIAL SEGMENTS OF SEQUENCES AND ARITHMETICAL DEFINABILITY

In the Kdegrees of infinite binary sequences, X is below Y if the prefixfree Kolmogorov complexity of the firs ..."

The initial segment strategy: A heuristic for route selection
 Memory & Cognition
, 2000
"... People often choose one route when traveling from point A to point B and a different route when traveling from point B to point A. To explain these route asymmetries, we propose that people rely on a heuristic (the initial segment strategy, or ISS) during route planning. This heuristic involves basi ..."
