The new old: Archaisms and anachronisms across media [Editorial]

Alphaville: Journal of Film and Screen Media, 2017
Transmedial and transcultural expressions of nostalgia are ubiquitous in our contemporary popular culture. Revival styles, vintage fashions, retro phenomena, skeumorphs and remediations are common presences in our increasingly digital cultural landscape,

Prefix codes for power laws [PDF]

2008 IEEE International Symposium on Information Theory, 2008
In prefix coding over an infinite alphabet, methods that consider specific distributions generally consider those that decline more quickly than a power law (e.g., a geometric distribution for Golomb coding). Particular power-law distributions, however, model many random variables encountered in practice.

Taguchi–Bayesian Sampling: A Roadmap for Polymer Database Construction Toward Small Representative Machine Learning

Advanced Intelligent Discovery, EarlyView.
This article establishes a Taguchi–Bayesian sampling strategy to reconstruct polymer processing–property landscape at minimal sampling cost, generically building the roadmap for materials database construction from sampling their vast design space. This sampling strategy is featured by an alternating lesson between uniformity and representativeness ...

The Interoperability Challenge in DFT Workflows Across Implementations

Advanced Intelligent Discovery, EarlyView.
Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.

Prefix codes, trees, and automata

Information Sciences, 1975
Abstract We investigate the relations between the tree representation of a prefix code C, its patterns, the minimal automaton which recognizes C ∗ , and the homomorphic images of the underlying algebra of . These relations provide us with an appealing formulation which allows us to state (and eventually solve) some problems ...

PbAT: A user‐friendly R/Shiny platform for data‐driven decision support in crop improvement

Applications in Plant Sciences, EarlyView.
Abstract Premise Modern plant breeding requires robust analysis of complex, multi‐environment datasets to identify superior genotypes. Although R offers powerful statistical packages, their use often requires programming expertise. Existing graphical user interface (GUI)‐based tools are either limited in scope or not openly accessible, leaving breeders

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.

Transceiver design and performance analysis for uplink SCMA based on CP-free OFDM

Dianxin kexue, 2021
A typical sparse code multiple access (SCMA) system utilizes orthogonal frequency division multiplexing (OFDM) technology with cyclic prefix (CP) to combat multipath fading in wireless channels.Therefore, its capacity is reduced by the CP-insertion.To ...

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 ...

Differential Space-Time Block Code Modulation for DS-CDMA Systems

EURASIP Journal on Advances in Signal Processing, 2002
A differential space-time block code (DSTBC) modulation scheme is used to improve the performance of DS-CDMA systems in fast time-dispersive fading channels. The resulting scheme is referred to as the differential space-time block code modulation for DS-
