We present an efficient method for obtaining the effective single-particle potential for electrons within density functional theory (DFT). In contrast to the independent atom model (IAM) often used to interpret microscopy experiments, our method includes the contributions from charge redistribution and exchange-correlation interactions in a realistic system. The method allows calculation of the...

When written in terms of θ-functions, the classical Frobenius–Stickelberger pseudo-addition formula takes a very simple form. Generalizations of this functional identity are studied, where the functions involved are derivatives (including derivatives with respect to the modular parameter) of the elliptic trilogarithm function introduced by Beilinson and Levin. A differential identity satisfied ...

The recognition of facial identity and expression are distinct tasks, with current models hypothesizing anatomic segregation of processing within a face-processing network. Using fMRI adaptation and a region-of-interest approach, we assessed how the perception of identity and expression changes in morphed stimuli affected the signal within this network, by contrasting (a) changes that crossed c...

This paper surveys the most important frameworks of analysis that could assist the ethnographer in detecting the functional mechanisms of such items as ‘elaboration of identity’ or ‘change of identity’. The relationship between speech and social class is also discussed and a model of ethnographic research is provided. The main argument is that research in the ethnography of communication presup...

We propose a fully functional identity-based encryption scheme (IBE). The scheme has chosen ciphertext security in the random oracle model assuming a variant of the computational DiffieHellman problem. Our system is based on bilinear maps between groups. The Weil pairing on elliptic curves is an example of such a map. We give precise definitions for secure identity based encryption schemes and ...

1. EXECUTIVE SUMMARY In this contribution we state the following thesis: The concept of federation represents a promising way to ease the establishment and operation of organizational and technical issues of identity management at a university. This concept fits well for most universities due to the fact that typically universities consist of " somewhat " independent organizational units like l...
