Stellarium: Finally at Version 1.0! And Beyond

“Smart pricing” has been the goal of the networking research community and the telecommunications industry for decades. Yet it has also proved remarkably hard to achieve. This paper presents a brief overview of telecommunications economics and technology, and the major changes that are taking place. Special emphasis is placed on the many popular but harmful notions that continue to lead this in...

Leukocyte recruitment to sites of inflammation is initiated by the selectin family of adhesion receptors. Recent research reveals that P-selectin binding to its ligand exhibits 'catch' to 'slip' bond transition that may help explain the shear threshold phenomenon.

This paper argues a new relevance for an old idea: decomposing transport protocols into a set of resuable building blocks that can be recomposed in different ways depending on application requirements. We conjecture that point-to-point applications may well be adequately served by the existing suite of monolithic protocol implementations, but widely-distributed peer-to-peer systems such as over...

In 2011 Stajano proposed Pico, a secure and easy-to-use alternative for passwords. Among the many proposals in this category, Pico stands out by being creative and convincing. However, the description as published leaves some details unspecified, and to the best of our knowledge the complete system has not yet been tested. This work presents detailed specifications and future-proof security pro...

Most electrophysiologists generally do not speak highly of leak currents. In reality, these conductances represent a crucial functional mechanism by which neurons control resting membrane potentials. A new study in Cell by Lu et al. has surprisingly confirmed the identity of the long-sought voltage-insensitive sodium leak conductance to be encoded by the third branch of the voltage-gated sodium...

Bioimpedance, themeasurement of the frequency-dependent resistance to the flow of low energy electrical currents between two electrodes on or within the body, has been investigated for various medical applications for over 50 years. Applications in cardiology date back to at least 1966 and have included attempts to estimate stroke volume, cardiac output, cardiac contractility and lung fluid vol...

Reset Reduction rules (Please note that the figure does not capture all the requirements for some rules (i.e., if a transition cannot have a reset arc (double-headed arc) or a place cannot be reset, the figure will not show this.)

This article addresses a paradox surrounding psychosocial maturity and self-actualizing in relation to well-being. Several stage theories of maturity (notably ego development; Loevinger, 1976) culminate in self-actualizing, which Maslow (1968) characterizes as the pinnacle of psychological health and well-being. However, empirical measures of maturity and well-being do not correlate. In a reana...
