Additive Quaternary Codes Related to Exceptional Linear Quaternary Codes [PDF]
IEEE Transactions on Information Theory, 2020 We study additive quaternary codes whose parameters are close to those of the extended cyclic [12; 6; 6]4-code or to the quaternary linear codes generated by the elliptic quadric in PG(3; 4) or its dual. In particular we characterize those codes in the category of additive codes and construct some additive codes whose parameters are better than those ...

THE ITALIAN QUATERNARY VOLCANISM
Alpine and Mediterranean Quaternary, 2023 The peninsular and insular Italy are punctuated by Quaternary volcanoes and their rocks constitute an important aliquot of the Italian Quaternary sedimentary successions. Also away from volcanoes themselves, volcanic ash layers are a common and frequent feature of the Quaternary records, which provide us with potential relevant stratigraphic and ...

Optics Express, 2019 We present a new Point Diffraction Interferometer (PDI). Binary adaptive optics (BAO) and Quaternary Adaptive Optics (QAO) can be performed with the help of this PDI as a wavefront sensor. The PDI interferogram, once binarized, is used in two consecutive steps to produce a quaternary mask with phase values 0, π/2, π and 3π/2.

During the Quaternary (last 2.58 Myr) polycyclic and progressive climate shifts controlled depositional systems in the southern North Sea region and shaped today’s Dutch landscapes. Continuous sediment supply from surrounding regions and strong basin subsidence resulted in thick depositional sequences that recorded information on successive regional ...

Quaternary and Pre-Quaternary Crustal Movements
The Quaternary Research (Daiyonki-Kenkyu), 1968 The problem discussed in this paper is whether the crustal movements in the Japanese Islands changed in nature or rate during the transition from the Tertiary to the Quaternary periods. The Late Tertiary sedimentary basins gradually migrated under the control of the orogenic movements which had begun in the Early Miocene.

Geologija, 2007 After a short-lived »ban«, the Quaternary has again been formalized as a chronostratigraphic unit, consisting of the Pleistocene and the Holocene. The exact base and the GSSP (Global Boundary Stratotype Section and Point) are yet to be formally recognized by the IUGS (International Union of Geological Sciences), however it is expected that the ...
