Despite progress in understanding chromatin function, the structure of the 30 nm chromatin fiber has remained elusive. However, with the recent crystal structure of a short tetranucleosomal array, the 30 nm fiber is beginning to come into view.

This document specifies PT-TLS, a TLS-based Posture Transport (PT) protocol. The PT-TLS protocol carries the Network Endpoint Assessment (NEA) message exchange under the protection of a Transport Layer Security (TLS) secured tunnel.

In this paper, we evaluate the effects of monetary policy on inflation and unemployment under different institutional arrangements in the labor market. We show that the effects of monetary policy on the real economy depend critically on the wage formation regime, and on the ways in which the restrictiveness of policy interacts with product price competition, wage setting centralization and the ...

World Health Organization estimates that 80% of the world population is affected of back pain during his life. Current practices to analyze back problems are expensive, subjective, and invasive. In this work, we propose a novel tool for posture and range of movement estimation based on the analysis of 3D information from depth maps. Given a set of keypoints defined by the user, RGB and depth da...

When the human fingertip is pressed against a surface or bent, the hemodynamic state of the fingertip is altered due to mechanical interactions between the fingernail and bone. Normal force, shear force, and finger extension/flexion all result in different patterns of blood volume beneath the fingernail. This phenomenon has been exploited in order to detect finger forces and finger posture by c...

A Robotic Computer, which moves its monitor "head" and "neck" but has no explicit face, is being designed to interact with users in a natural way for applications such as learning, rapport-building, interactive teaching, and posture improvement. In all these applications, the robot will need to move in subtle ways that express its state, and that promote appropriate movements in the user, but t...

This paper introduces a formalized definition of an external space representation and proposes a virtual navigation paradigm as a mean for space integration from tactile snapshots. Rules for the design of indoor experimental environments to be used in virtual navigation are presented; they take into account posture modifications of the subject and the cognitive load of the elementary tasks inhe...
