Discrete & Computational Geometry, 2010 A line g is a transversal to a family F of convex polytopes in 3-dimensional space if it intersects every member of F. If, in addition, g is an isolated point of the space of line transversals to F, we say that F is a pinning of g. We show that any minimal pinning of a line by convex polytopes such that no face of a polytope is coplanar with the line ...

Igra ustvarjalnosti - Creativity game, 2013 The perception of elements in a system often creates their interdependence, interconditionality, and suppression. The lines from a basic geometrical element have become the model of a reductive world based on isolation according to certain criteria such as function, structure, and social organization.

Combinatorica, 2013 One of the De Bruijn - Erdos theorems deals with finite hypergraphs where every two vertices belong to precisely one hyperedge. It asserts that, except in the perverse case where a single hyperedge equals the whole vertex set, the number of hyperedges is at least the number of vertices and the two numbers are equal if and only if the hypergraph belongs

Revue internationale de psychosociologie et de gestion des comportements organisationnels, 2017 En appréhendant le processus de recherche comme une expérience vécue, on s’aperçoit que l’existence de deadlines confère à la recherche une temporalité et un sens bien spécifiques. Par un récit autoethnographique et une écriture performative, l’auteur prend conscience que plus il s’approche de la fin et plus croissent la vitalité, les idées, son ...

On-Line/Off-Line Digital Signatures [PDF]
Journal of Cryptology, 1996 A new type of signature scheme is proposed. It consists of two phases. The first phase is performed off-line, before the message to be signed is even known. The second phase is performed on-line, once the message to be signed is known, and is supposed to be very fast. A method for constructing such on-line/off-line signature schemes is presented.

BMC Biology, 2015 The pea aphid Acyrthosiphon pisum is an agriculturally important pest of leguminous plants including peas and broad beans. The widespread use of chemical pesticides impacts heavily on the environment, and increases pesticide-resistant pea aphid populations, so alternative strategies are being actively sought.

Current Biology, 2004 Fish receive much of their sensory information – used, for example, to guide their stunning schooling behaviour – from a particular sensory organ system, the lateral line. Hair cells sitting in neuromast organs that are scattered along the flank of the fish sense water movements, much as hair cells in our inner ear sense air movements. The lateral line
