In 1998, Boneh, Durfee and Frankel described several attacks against RSA enabling an attacker given a fraction of the bits of the private exponent d to recover all of d. These attacks were later improved and extended in various ways. They however always consider that the private exponent d is smaller than the RSA modulus N . When it comes to implementation, d can be enlarged to a value larger t...

We present the system d, an extended type system with lambda-typed lambdaexpressions. It is related to type systems originating from the Automath project. d extends existing lambda-typed systems by an existential abstraction operator as well as propositional operators. β-reduction is extended to also normalize negated expressions using a subset of the laws of classical negation, hence d is norm...

Generalised geometry studies structures on a d-dimensional manifold with a metric and 2-form gauge field on which there is a natural action of the group SO(d, d). This is generalised to d-dimensional manifolds with a metric and 3-form gauge field on which there is a natural action of the group Ed. This provides a framework for the discussion of M-theory solutions with flux. A different generali...

In the Rectangle Escape problem, we are given a set of rectangles S in a rectangular region R, and we would like to extend these rectangles to one of the four sides of R while ensuring that the maximum number of overlaps is minimized. More formally, define the density of a point p in R as the number of extended rectangles that contain p. The question is then to find an extension with the smalle...

A field trial was conducted on several hundred farms in The Netherlands to compare the fertilizing capacity of boar spermatozoa stored for 1, 2, or 3 d at 18 C in either Kiev or Beltsville liquid extender (BL-1). Two storage volumes (25 and 100 ml) were used. Twelve Dutch Landrace boars, all in routine commercial artificial insemination service, provided the semen in twice-a-week collections. O...

New extended superspaces associated with topological charge algebras of the D-brane are used to construct D-brane actions without worldvolume gauge fields. The actions are shown to be kappa-symmetric under an appropriately chosen right group action.

A bstract We study the effect of D-instantons on closed string scattering amplitudes in two-dimensional type 0B theory from worldsheet perspective. find that contribution a pair D-instanton and anti-D-instanton to reflection amplitude, with suitable contour prescription for integration over moduli space, agrees corresponding leading non-perturbative corrections proposed dual matrix quantum mech...

We formulate WZW models based on a centrally extended version of the Euclidean group in d-dimensions. We obtain string backgrounds corresponding to conformal σ-models in D = d space-time dimensions with exact central charge c = d and d(d − 1)/2 null Killing vectors. By identifying the corresponding conformal field theory we show that the one loop results coincide with the exact ones up to a shi...
