The Sybil Attack

"... Largescale peertopeer systems face security threats from faulty or hostile remote computing elements. To resist these threats, many such systems employ redundancy. However, if a single faulty entity can present multiple identities, it can control a substantial fraction of the system, thereby unde ..."

The English Noun Phrase in its Sentential Aspect
 PH.D. DISSERTATION MIT

Braided central elements

"... We present and study two families of polynomials with coefficients in the center of the universal enveloping algebra. These polynomials are analogues of a determinant and a characteristic polynomial of a certain noncommutative matrix, labeled by irreducible representations of gl n(C). The matrix is ..."

We present and study two families of polynomials with coefficients in the center of the universal enveloping algebra. These polynomials are analogues of a determinant and a characteristic polynomial of a certain noncommutative matrix, labeled by irreducible representations of gl n(C). The matrix is an image of the universal Rmatrix of a Yangian of gl n(C) under certain representation. We compute the polynomials explicitly for gl 2(C) and establish connections between the first family of polynomials and higher Capelli identities through some sort of plethysm. 1
Central Elements of Effect Algebras Josef Tkadlec1
"... Central elements of an effect algebra can be characterized by means of a weak form of distributivity and a maximality property. We give examples when these two conditions are fulfilled. Central elements and the center (the set of all central elements) play an important role in quantum structures—the ..."

Specifying Distributed Software Architectures

"... There is a real need for clear and sound design specifications of distributed systems at the architectural level. This is the level of the design which deals with the highlevel organisation of computational elements and the interactions between those elements. The paper presents the Darwin notation ..."

lium discoideum culminates with the assembly of a rugged, environmentally resistant spore coat around each spore cell. After synthesis, the proteins that will constitute the coat are stored in prespore vesicles (PSVs) until an unknown developmental signal triggers the PSVs to move to the cell surface where they fuse with the plasma membrane and secrete their cargo by exocytosis. These events occur synchronously in 80 % of the cells in each developing multicellular aggregate, and thus the system offers a unique opportunity to study the developmental regulation of protein secretion in situ. Proteomic analysis of purified PSVs identified many of the constituent proteins, which in turn has lead to novel hypotheses and new experimental avenues regarding the molecular mechanisms regulating
Analogical Mapping by Constraint Satisfaction
 COGNITIVE SCIENCE 13, 295 (1989)
, 1989
"... A theory of analogical mopping between source and target analogs based upon interacting structural, semantic, and pragmatic constraints is proposed here. The structural constraint of fsomorphfsm encourages mappings that maximize the consistency of relational corresondences between the elements of th ..."

of the two analogs. The constraint of semantic similarity supports mapping hypotheses to the degree that mapped predicates have similar meanings. The constraint of pragmatic centrality fovors mappings involving elements the analogist believes to be important in order to achieve the purpose for which
