Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

Archaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Efficient and Compact Representations of Prefix Codes [PDF]

IEEE Transactions on Information Theory, 2015
Most of the attention in statistical compression is given to the space used by the compressed sequence, a problem completely solved with optimal prefix codes. However, in many applications, the storage space used to represent the prefix code itself can be an issue. In this paper we introduce and compare several techniques to store prefix codes. Let $N$

Phantom citations: An empirical study of non‐existent and unverifiable references in scholarly literature

Journal of the Association for Information Science and Technology, EarlyView.
Abstract The integrity of scholarly communication depends critically on the accuracy and verifiability of cited references. Citations enable readers to trace prior work, assess evidence, and situate new contributions within the existing literature. However, concerns have emerged regarding the presence of references in published papers that cannot be ...

Decoding of ${\mathbb{Z}}_{2^S}$ Linear Generalized Kerdock Codes

Mathematics
Many families of binary nonlinear codes (e.g., Kerdock, Goethals, Delsarte–Goethals, Preparata) can be very simply constructed from linear codes over the Z4 ring (ring of integers modulo 4), by applying the Gray map to the quaternary symbols. Generalized

Knowing education in Thailand like a global expert organisation: Politics, context and data

British Educational Research Journal, EarlyView.
Abstract Global expert organisations play increasingly significant roles in the way that education is understood and governed internationally, including by influencing the discourses through which education is conceptualised and shaping norms of what counts as success, failure, progress and the most desirable visions for the future.

P-LDPC coded image transmission with OFDM over underwater acoustic channel

Acta Polytechnica
Underwater environment is still an attractive area to explore and exploit by human beings. However, underwater characteristics limit communications due to harsh channel conditions, and efficient channel codes are essential to deploy. This study presents

Utterance evolution: the road to generative, combinatorial communicators

Biological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

Indonesia 5G Channel Model Under Foliage Effect

Buletin Pos dan Telekomunikasi: Media Komunikasi Ilmiah, 2019
The performance of communications is determined by the channel, therefore knowledge of channel model of a country is important. This paper proposes (i) the fifth telecommunication generation (5G) Indonesia channel model and (ii) a framework to derive the
