DOI: 10.1016/j.jtbi.2021.110661

Abstract: A series of prior publications has reported unusual properties of the set of genetically encoded amino acids shared by all known life. This work uses quantitative measures (descriptors) of size, charge and hydrophobicity to compare… read more here.

DOI: 10.1021/acs.jctc.9b01079

Abstract: Evolution has yielded biopolymers that are constructed from exactly four building blocks and are able to support Darwinian evolution. Synthetic biology aims to extend this alphabet, and we recently showed that 8-letter (hachimoji) DNA can… read more here.

DOI: 10.1021/jacs.2c12987

Abstract: Whereas modern proteins rely on a quasi-universal repertoire of 20 canonical amino acids (AAs), numerous lines of evidence suggest that ancient proteins relied on a limited alphabet of 10 ‘early’ AAs, and that the 10… read more here.

DOI: 10.1080/10888438.2025.2481064

Abstract: ABSTRACT Purpose We hypothesize that alphabet learning during early childhood matters for reading and spelling in alphabetic languages. In this preregistered study, we conceptually replicated and extended work on children’s alphabet learning trajectories and associations… read more here.

DOI: 10.1109/tit.2017.2661990

Abstract: This paper introduces a convenient strategy for coding and predicting sequences of independent, identically distributed random variables generated from a large alphabet of size $m$ . In particular, the size of the sample is allowed… read more here.

DOI: 10.1109/tit.2023.3236425

Abstract: Convolutional codes are essential in a wide range of practical applications due to their efficient non-algebraic decoding algorithms. In this paper, we first propose a new family of matrices over finite fields by combining Vandermonde… read more here.

DOI: 10.1353/tech.2018.0149

Abstract: ABSTRACT:Since the late 1980s, computers throughout the Sinophone world have featured QWERTY keyboards, employing input techniques that rely upon the Latin alphabet. In this article, I argue that historians of modern China and modern information… read more here.

DOI: 10.3390/math12040525

Abstract: Language barriers and the communication difficulties of individuals with developmental disabilities are two major causes of communication problems that societies worldwide encounter. A particularly challenging group is hearing-impaired people who have difficulties with communication, reading,… read more here.
