We first study some families of maximal real subfields of cyclotomic fields with even class number, and then explore the implications of large plus class numbers of cyclotomic fields. We also discuss capitulation of the minus part and the behaviour of p-class groups in cyclic ramified p-extensions. This is a continuation of [13]; parts I and II are independent, but will be used in part III. 6. ...
Running title: Semi-automated hippocampal subfield segmentation in pediatric sample + Authors had equal contributions.
In their paper [D–M–M2], van den Dries, Macintyre and Marker give an explicit construction of a nonarchimedean model of the theory of the reals with restricted analytic functions and exponentiation. This model, called the logarithmic exponential power series field, lies in a generalized power series field. They use the results of Ressayre and Mourgues about truncation-closed embeddings to answe...
UPLICkey cryptographic is the fundamental technology in secure communications. It was devised by Diffie and Hellman [8], in 1976, to secret key distribution. In 1985, Coblitz [5] and Miller [7] independently proposed the implementation of a public key cryptosystem [3] using elliptic curve. The elliptic curve discrete logarithm problem appeared to be much more difficult than above discussed algo...
BACKGROUND AND PURPOSE High resolution 7T MRI is increasingly used to investigate hippocampal subfields in vivo, but most studies rely on manual segmentation which is labor intensive. We aimed to evaluate an automated technique to segment hippocampal subfields and the entorhinal cortex at 7T MRI. MATERIALS AND METHODS The cornu ammonis (CA)1, CA2, CA3, dentate gyrus, subiculum, and entorhinal...
