We explore a novel interaction technique using forcefeedback devices for creative manipulation of 3D models that combines interactive mesh deformation with painting a deformation property map. Painting a deformation map permits the artist to easily assign different values of “malleability” to specific areas of the model in order to locally manipulate the deformation behavior during interactive ...

Non-malleability is an important security property of commitment schemes. The property means security against the man-in-the-middle attack, and it is defined and proved in the simulation paradigm using the corresponding simulator. Many known non-malleable commitment schemes have the common drawback that their corresponding simulators do not work in a straight-line manner, requires rewinding of ...

In a longitudinal study, the authors housed wild-caught juvenile male cowbirds (Molothrus ater artemisiae) with female cowbirds or canaries (Serinus canaria) from August until May. The males were then exposed to 3 social contexts. Males housed with canaries directed more vocalizations to canaries than to female cowbirds. Males housed with female cowbirds vocalized most to other males. The data ...

This research examines the notion that guilt, the negative emotion stemming from a failure to meet a self-held standard of behavior, leads to preferences for products enabling self-improvement, even in domains unrelated to the original source of the guilt. Examining consumer responses to real products, this research shows that such effects arise because guilt—by its focus on previous wrongdoing...

The notion of non-malleable cryptography, an extension of semantically secure cryptography , is deened. Informally, the additional requirement is that given the ciphertext it is impossible to generate a diierent ciphertext so that the respective plaintexts are related. The same concept makes sense in the contexts of string commitment and zero-knowledge proofs of possession of knowledge. Non-mal...

A non-malleable code protects messages against various classes of tampering. Informally, a code is non-malleable if the message contained in a tampered codeword is either the original message, or a completely unrelated one. Although existence of such codes for various rich classes of tampering functions is known, explicit constructions exist only for “compartmentalized” tampering functions: i.e...
