Introduction: MRI of the lung is still a challenging task due to its inherently low proton density, continuous movement caused by respiration and heartbeat, as well as a very short T2* relaxation time of roughly 1-2 ms at 1.5 T [1]. The latter of which can be overcome by using Spin-Echo type sequences which correct for additional spin dephasing owing to inhomogeneities at the numerous air-tissu...

Given ν > 1 2 and δ > 0 arbitrary, we prove the existence of energy solutions of (0.1) ∂ttu−∆u− u = 0 in R3+1 that blow up exactly at r = t = 0 as t → 0−. These solutions are radial and of the form u = λ(t) 1 2W (λ(t)r)+η(r, t) inside the cone r ≤ t, where λ(t) = t−1−ν , W (r) = (1 + r2/3)− 1 2 is the stationary solution of (0.1), and η is a radiation term with Z [r≤t] ` |∇η(x, t)| + |ηt(x, t)|...

MOTIVATION To date, only a few distinct successful approaches have been introduced to reconstruct a protein 3D structure from a map of contacts between its amino acid residues (a 2D contact map). Current algorithms can infer structures from information-rich contact maps that contain a limited fraction of erroneous predictions. However, it is difficult to reconstruct 3D structures from predicted...

In 2009 we started, within the dedicated HARPS-Upgrade GTO program, an intense radial-velocity monitoring of a few nearby, slowly-rotating and quiet solar-type stars. The goal of this campaign is to gather, with high cadence and continuity, very-precise radial-velocity data in order to detect tiny signatures of very-low-mass stars potentially in the habitable zone of their parent stars. 10 star...

Abstract Every non-convex pair $(C, D)$ ( C , D ) may not have proximal normal structure even in a Hilbert space. In this article, we use cyclic relatively nonexpansive maps with respect to orbits show the presence of best proximity points $C...

The development of new interface tools for intelligence analysis requires a thorough knowledge of the analytical process, and a comprehensive understanding of analyst activities that can best benefit from intelligent user interface technology. However, due to the secretive nature of the domain, there have been relatively few public studies examining analyst behavior. In this paper, we present t...

Often research on online communities could be compared to archaeology [16]: researchers look at patterns in digital traces that members leave to characterise the community they belong to. Relatively easy access to these traces and a growing number of methods and tools to collect and analyse them make such analysis increasingly attractive. However, a researcher is faced with the difficult task o...
