Calcified vertebral artery and "dense basilar artery sign" in a patient with basilar territory infarction.
Diagnosis of posterior circulation stroke (PCS) may get delayed or missed in patients with atypical signs. Magnetic resonance imaging (MRI), considered to be superior to computerized tomography (CT) in PCS, too is not 100% sensitive, as 20% of patients with PCS may have a negative diffusion-weighted MRI at admission. Moreover, MRI is not universally available and CT is often the initial imaging...
متن کاملAsterixis as a Focal Neurologic Sign: Report of Three Cases and Literature Review
Asterixis, firstly described in metabolic encephalopathies, may occur unilaterally in patients with various focal brain diseases. Although hardly localizing, most reported cases have showed a contralateral thalamic pathology; but Lesions in the medial frontal lobe, parietal lobe, brain stem, basal ganglia, insular lesions, may also cause unilateral asterixis. In this article, three cases of acu...
متن کاملCommon Territory
The IMP research tradition has always been open to the cross-fertilisation of ideas with other social science disciplines that study similar phenomena. Recent years have seen a growing interest among IMP researchers in phenomena such as regional strategic networks, spatial clusters and innovation and new business development in networks. IMP papers published on these topics are increasingly cit...
متن کاملThree-body recombination with mixed sign light particles
Using a classical trajectory Monte Carlo method, we have computed the threebody recombination (two free positrons and an anti-proton scattering into one free positron and an anti-hydrogen atom: e+ + e+ + p̄ → H̄ + e+) in the presence of electrons. By simply reversing the sign of all of the particles, these results can be applied to three-body recombination of matter in the presence of positrons. ...
متن کاملThree alternating sign matrix identities in search of bijective proofs
These are rich combinatorial objects with connections to many problems in algebraic combinatorics (see [2], [3], [12]). They also have many different representations. The representation that was used in Kuperberg’s proof of the counting function for alternating sign matrices [9] and Zeilberger’s proof of the refined alternating sign matrix conjecture [14] is the six-vertex model of statistical ...
