Method and System for Emulating a Mouse on a Multi-Touch Sensitive Surface

Abstract: A computer implemented method for emulating a mouse with a multi-touch sensitive display surface. Sensing a touching, movement or tapping by one or several fingers or fist emulates mechanical mouse functionality. Sensing a first touching by a first finger at a first location on a multi-touch sensitive display surface and sensing concurrently a second touching by a second finger at a second location on the multi-touch sensitive display surface displays a graphic object on the multi-touch display surface at a position dependent on the first location and the second location to emulate moving a mouse.

Measurements of the proton elastic form factors for 1 <= Q2 <= 3 (GeV/c)2 at SLAC.

Abstract: We report measurements of the proton form factors [ital G][sub [ital E]][sup [ital p]] and [ital G][sub [ital M]][sup [ital p]] extracted from elastic scattering in the range 1[le][ital Q][sup 2][le]3 (GeV/[ital c])[sup 2] with total uncertainties [lt] 15% in [ital G][sub [ital E]][sup [ital p]] and [lt] 3% in [ital G][sub [ital M]][sup [ital p]]. Comparisons are made to theoretical models, including those based on perturbative QCD, vector-meson dominance, QCD sum rules, and diquark constituents in the proton. The results for [ital G][sub [ital E]][sup [ital p]] are somewhat larger than indicated by most theoretical parametrizations, and the ratios of the Pauli and Dirac form factors [ital Q][sup 2]([ital F][sub 2][sup [ital p]]/[ital F][sub 1][sup [ital p]]) are lower in value and demonstrate a weaker [ital Q][sup 2] dependence than those predictions. A global extraction of the elastic form factors from several experiments in the range 0.1 [lt] [ital Q][sup 2] [lt] 10 (GeV/[ital c])[sup 2] is also presented.

COLLAGEN: when agents collaborate with people

Abstract: We take the position that autonomous agents, when they interact with people, should be governed by the same principles that underlie human collaboration. These principles come from research in computational linguistics, specifically collaborative discourse theory, which describes how people communicate and coordinate their activities in the context of shared tasks. We have implemented a prototype toolkit, called Collagen, which embodies collaborative discourse principles, and used it to build a collaborative interface agent for a simple air travel application. The potential benefits of this approach include application-independence, naturalness of use, and ease of learning, without requiring natural language understanding by the agent.

Efficient attribute-based signatures for non-monotone predicates in the standard model

Abstract: This paper presents a fully secure (adaptive-predicate unforgeable and private) attribute-based signature (ABS) scheme in the standard model. The security of the proposed ABS scheme is proven under standard assumptions, the decisional linear (DLIN) assumption and the existence of collision resistant (CR) hash functions. The admissible predicates of the proposed ABS scheme are more general than those of the existing ABS schemes, i.e., the proposed ABS scheme is the first to support general non-monotone predicates, which can be expressed using NOT gates as well as AND, OR, and Threshold gates, while the existing ABS schemes only support monotone predicates. The proposed ABS scheme is efficient and practical. Its efficiency is comparable to (several times worse than) that of the most efficient (almost optimally efficient) ABS scheme the security for which is proven in the generic group model.

Adaptively attribute-hiding (hierarchical) inner product encryption

Abstract: This paper proposes the first inner product encryption (IPE) scheme that is adaptively secure and fully attribute-hiding (attribute-hiding in the sense of the definition by Katz, Sahai and Waters), while the existing IPE schemes are either fully attribute-hiding but selectively secure or adaptively secure but weakly attribute-hiding. The proposed IPE scheme is proven to be adaptively secure and fully attribute-hiding under the decisional linear assumption in the standard model. The IPE scheme is comparably as efficient as the existing attribute-hiding IPE schemes. We also present a variant of the proposed IPE scheme with the same security that achieves shorter public and secret keys. A hierarchical IPE scheme can be constructed that is also adaptively secure and fully attribute-hiding under the same assumption. In this paper, we extend the dual system encryption technique by Waters into a more general manner, in which new forms of ciphertext and secret keys are employed and new types of information theoretical tricks are introduced along with several forms of computational reduction.
