A distinction between forms of social identity formation in small interactive groups is investigated. In groups in which a common identity is available or given, norms for individual behavior may be deduced from group properties (deductive identity). In groups in which interpersonal relations are central, a group identity may also be induced from individual group members' contributions, making ...

In this paper, we describe a novel user interface for the visual defin ition of temporal abstractions based on a set of intuitive metaphors, which re present both temporal features and logical relations of abstractions.

The discovery of a diverse and unique subset of ion channels in T lymphocytes has led to a rapidly growing body of knowledge about their functional roles in the immune system. Potent and specific blockers have provided molecular tools to probe channel structure-function relations and to elucidate the involvement of K+, Ca2+, and Cl- channels in T-cell activation and cell volume regulation. Rece...

[1] A survey of Advanced Rio‐Imaging Experiment in Scandinavia data reveals evidence for a previously overlooked generation mechanism of high azimuthal wave number magnetospheric waves. Here we present observations of pulsating cosmic noise absorption with azimuthal wave numbers as high as 380, suggestive of precipitation modulation by magnetospheric waves. Dispersion relations of the small‐sca...

The understanding of the molecular properties and structure-function relations of ion channels has advanced tremendously during the past few years. In this review I will try to summarize briefly the current advances in the field of calcium channel proteins and outline the problems facing researchers at present. I will concentrate exclusively on uertebrate voltage-dependent Ca*+ channels, becaus...

We consider a one-dimensional steady-state Poisson-Nernst-Planck type model for ionic flow through membrane channels. Improving the classical Poisson-Nernst-Planck models where ion species are treated as point charges, this model includes ionic interaction due to finite sizes of ion species modeled by hard sphere potential from the Density Functional Theory. The resulting problem is a singularl...

We present a way of treating the problem of the interaction of a single trapped ion with laser beams based on successive aplications of unitary transformations onto the Hamiltonian. This allows the diagonalization of the Hamil-tonian, by means of recursive relations, without performing the Lamb-Dicke approximation.

We have determined the full magnetic dispersion relations of multiferroic BiFeO3. In particular, two excitation gaps originating from magnetic anisotropies have been clearly observed. The direct observation of the gaps enables us to accurately determine the Dzyaloshinskii-Moriya (DM) interaction and the single ion anisotropy. The DM interaction supports a sizable magnetoelectric coupling in thi...
