We identified a novel human parechovirus (HPeV) type (K251176-02) from a neonate with fever. Analysis of the complete genome showed K251176-02 to be a new HPeV genotype. Since K251176-02 could not be neutralized with antibodies against known HPeV serotypes 1-3, it should be classified as a fourth HPeV serotype.

We consider the consequences of describing the metric properties of space-time through a quartic line element ds = Gμνλρdx dxdxdx. The associated ”metric” is a fourth-rank tensor Gμνλρ. We construct a theory for the gravitational field based on the fourth-rank metric Gμνλρ which is conformally invariant in four dimensions. In the absence of matter the fourth-rank metric becomes of the form Gμνλ...

With high-throughput sequencing, transcriptomics, and proteomics no longer in their “infancy” as described in the preface by author T.A. Brown, Genomes 4 offers an expansive review on a broad spectrum of topics in genetics ranging from the central dogma of genes coding for proteins, to the fine technical details of genome mapping. This edition retains the four-part organization from the previou...

Dr. Nelson has no financial or proprietary interest in the materials presented herein. doi: 10.3928/01913913-20121008-01 Acute fourth nerve paresis is probably the most frequent cause of acquired vertical diplopia. In this issue, Khaier et al. found that many cases of acute fourth nerve paresis have a benign etiology and clinical course. Although the most common cause of vertical diplopia relat...

The presence of Neandertals in Europe and Western Eurasia before the arrival of anatomically modern humans is well supported by archaeological and paleontological data. In contrast, fossil evidence for Denisovans, a sister group of Neandertals recently identified on the basis of DNA sequences, is limited to three specimens, all of which originate from Denisova Cave in the Altai Mountains (Siber...

We stand on the brink of a technological revolution that will fundamentally alter the way we live, work, and relate to one another. In its scale, scope, and complexity, the transformation will be unlike anything humankind has experienced before. We do not yet know just how it will unfold, but one thing is clear: the response to it must be integrated and comprehensive, involving all stakeholders...

We present and implement a fourth-order projective dependency parsing algorithm that effectively utilizes both “grand-sibling” style and “tri-sibling” style interactions of third-order and “grand-tri-sibling” style interactions of forth-order factored parts for performance enhancement. This algorithm requires O(n5) time and O(n4) space. We implement and evaluate the parser on two languages—Engl...
