Induced sensorimotor brain plasticity controls pain in phantom limb patients
Nature Communications, 2016 The cause of pain in a phantom limb after partial or complete deafferentation is an important problem. A popular but increasingly controversial theory is that it results from maladaptive reorganization of the sensorimotor cortex, suggesting that ...

Can Phantom-Dominated Universe Decelerate Also in Future ? [PDF]
arXiv, 2007 Here Randall-Sundrum brane-gravity models of the homogeneous and flat universe, dominated by phantom fluid, is considered. It is noted that brane-gravity corrections effect the behaviour of phantom fluid in RS-II model (where brane-tension $\lambda$ is negative) drastically.

Journal of Nuclear Medicine, 2015 The Clinical Trials Network (CTN) of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) operates a PET/CT phantom imaging program using the CTN’s oncology clinical simulator phantom, designed to validate scanners at sites that wish to ...

Active promoters give rise to false positive ‘Phantom Peaks’ in ChIP-seq experiments
Nucleic Acids Research, 2015 Chromatin immunoprecipitation (ChIP) is widely used to identify chromosomal binding sites. Chromatin proteins are cross-linked to their target sequences in living cells.

Properties of singularities in the (phantom) dark energy universe [PDF]
, 2005 The properties of future singularities are investigated in the universe dominated by dark energy including the phantom-type fluid. We classify the finite-time singularities into four classes and explicitly present the models which give rise to these ...

Phantom depth and stable phantom exactness [PDF]
Transactions of the American Mathematical Society, Volume 359,
Number 10, October 2007, pp 4829-4864, 2005 Phantom depth, phantom nonzerodivisors, and phantom exact sequences are analogues of the non-"phantom" notions which have been useful in tackling the (very difficult) localization problem in tight closure theory. In the present paper, these notions are developed further and partially reworked. For instance, although no analogue of a long exact sequence

EJNMMI Physics, 2015 BackgroundIn integrated PET/MR hybrid imaging the evaluation of PET performance characteristics according to the NEMA standard NU 2–2007 is challenging because of incomplete MR-based attenuation correction (AC) for phantom imaging.

Do phantom Cuntz-Krieger algebras exist? [PDF]
arXiv, 2012 If phantom Cuntz-Krieger algebras do not exist, then real rank zero Cuntz-Krieger algebras can be characterized by outer properties. In this survey paper, a summary of the known results on non-existence of phantom Cuntz-Krieger algebras is given.

Relative phantom maps and rational homotopy [PDF]
arXiv, 2019 We generalize some results of Gray and McGibbon-Roitberg on relations between phantom maps and rational homotopy to relative phantom maps. Since the $\lim^1$ and the profinite completion techniques do not apply to relative phantom maps, we develop new techniques.
