Stirring: The Eckart paradigm revisited

Cutting Edge: Paradigm Revisited: Antibody

Eckart Viehweg And

Example 0.1. Let f : X → P be a non-isotrivial semistable family of Abelian varieties of dimension g over the complex line, then: i. s = #{ singular fibres } ≥ 4. ii. s = 4 if and only if f is isogenous to E ×P1 E ×P1 · · · ×P1 E where E → P is one of the 6 modular families of elliptic curves, smooth over P \ {y1, . . . , y4} for some distinct points y1, . . . , y4 ∈ P (as described in [Beauvil...

Robustness versus evolvability: a paradigm revisited.

Evolvability is the property of a biological system to quickly adapt to new requirements. Robustness seems to be the opposite. Nonetheless many biological systems display both properties-a puzzling observation, which has caused many debates over the last decades. A recently published model by Draghi et al. [Nature 463, 353-355 (2010)] elegantly circumvents complications of earlier in silico stu...

Leukocyte recruitment in the microcirculation: the rolling paradigm revisited.

Intravital microscopy has done much to elucidate the cascade of events involved in the recruitment of leukocytes to sites of inflammation. Here we review the physiological relevance of leukocyte rolling and some of the important subtleties of this process, highlighting limitations in our knowledge and directions for future investigation.

On the (In)security of the Fiat-Shamir Paradigm, Revisited

The Fiat-Shamir paradigm [CRYPTO’86] is a heuristic for converting 3-round identification schemes into signature schemes, and more generally, for collapsing rounds in public-coin interactive protocols. This heuristic is very popular both in theory and in practice, and many researchers have studied its security (and insecurity). In this work, we continue this study. As our main result, we show t...
