An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis
Annals of Clinical and Translational Neurology, EarlyView.By applying the tensor model, we analysed lesion orientation and the directionality of lesion expansion/contraction in multiple sclerosis. Each lesion is summarized as an ellipsoid, and the tensor model is applied to calculate lesion anisotropy. From the top to the bottom white matter atlas, surface‐in gradient segmentation and venous atlas used in the

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACTObjectiveCerebrospinal fluid (CSF) orexin‐A has been suggested to be a biomarker of Alzheimer disease (AD). In both cognitively unimpaired healthy older adults and individuals with symptomatic AD, CSF orexin‐A is positively associated with CSF Aβ42, p‐tau181, and total tau (t‐tau) concentrations.

Denizli Havzası’nda bulunan Kuvaterner yaşlı omurgalı (memeli) fosil bulguları ve önemi
Pamukkale University Journal of Engineering Sciences, 2018 Denizli havzası batı Anadolu’da yer alır ve erken orta Miyosen-Kuvaterner yaşlı karasal tortulları barındırır. Bu karasal tortullarda pek çok memeli fosil lokalitesi bulunmuştur. Özellikle Kuvaterner devrinde bulunan küçük-büyük memeli fosilleri, cins ve

A method for constructing quaternary Hermitian self-dual codes and an application to quantum codes [PDF]
arXivWe introduce quaternary modified four $\mu$-circulant codes as a modification of four circulant codes. We give basic properties of quaternary modified four $\mu$-circulant Hermitian self-dual codes. We also construct quaternary modified four $\mu$-circulant Hermitian self-dual codes having large minimum weights.

Quaternary Science Reviews, 2004 Abstract The Quaternary System is under threat of extinction as a chronostratigraphic unit in the international Geological Time Scale. In its place, the Neogene System (previously comprising Miocene and Pliocene Series), is to be extended to include the Pleistocene and Holocene Series.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Febrile infection related epilepsy syndrome (FIRES) is a rare presentation of refractory status epilepticus with immune dysregulation as a potential pathologic mechanism. Despite promising results from second‐line immunomodulators, approximately 30% remain refractory to treatment.

Quaternary matroids are vf-safe [PDF]
arXiv, 2013 Binary delta-matroids are closed under vertex flips, which consist of the natural operations of twist and loop complementation. In this note we provide an extension of this result from GF(2) to GF(4). As a consequence, quaternary matroids are "safe" under vertex flips (vf-safe for short).
