Integrated Stratigraphy of the Marine Early Pleistocene in Umbria
Geosciences, 2020 Through time, the wide area between southeastern Tuscany, northeastern Latium, and western Umbria has been revealed as a crucial area for understanding the evolution of Neogene basins in northern Apennine.

Classification of optimal quaternary Hermitian LCD codes of dimension $2$ [PDF]
arXiv, 2020 Hermitian linear complementary dual codes are linear codes whose intersection with their Hermitian dual code is trivial. The largest minimum weight among quaternary Hermitian linear complementary dual codes of dimension $2$ is known for each length. We give the complete classification of optimal quaternary Hermitian linear complementary dual codes of ...

Atmospheric effects on Quaternary polarization encoding for free space communication, laboratory simulation [PDF]
, 2015 We have simulated atmospheric effects such as fog and smoke in laboratory environment to simulate depolarisation due to atmospheric effects during a free space optical communi- cation. This has been used to study noise in two components of quaternary encoding for polarization shift keying.

New constructions of quaternary bent functions [PDF]
arXiv, 2013 In this paper, a new construction of quaternary bent functions from quaternary quadratic forms over Galois rings of characteristic 4 is proposed. Based on this construction, several new classes of quaternary bent functions are obtained, and as a consequence, several new classes of quadratic binary bent and semi-bent functions in polynomial forms are ...

A Database of $\mathbb{Z}_4$ Codes [PDF]
Journal of Combinatorics, Information and System Sciences, Vol. 34
No. 1-4 Comb, 2009, p: 1-12, 2015 There has been much research on codes over $\mathbb{Z}_4$, sometimes called quaternary codes, for over a decade. Yet, no database is available for best known quaternary codes. This work introduces a new database for quaternary codes. It also presents a new search algorithm called genetic code search (GCS), as well as new quaternary codes obtained by ...
