Self-dual twisted generalized Reed-Solomon codes [PDF]

open access: yes, 2022
In this paper, by using some properties for linear algebra methods, the parity-check matrices for twisted generalized Reed-Solomon codes with any given hook $h$ and twist $t$ are presented, and then a sufficient and necessary condition for the twisted ...

Global Carbon Investment in Terrestrial Biological Nitrogen Fixation

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Biological nitrogen (N) fixation (BNF) provides the N needed to produce proteins and other biological building blocks, helping feed humanity and mitigate climate change. Due to its high energetic cost compared to other forms of N acquisition, biotic investment in BNF indicates N limitation. Globally gridded BNF flux data provide an opportunity

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): short‐term peri‐operative analgesic use

open access: yesAnaesthesia, Volume 81, Issue 8, Page 1057-1067, August 2026.
Summary Introduction An increasing proportion of complex surgical procedures are being performed in the UK as day‐cases, with variable and limited follow up. Discharge prescriptions must provide adequate analgesia, while considering the safety of the patient and public, following best practice guidance and good opioid stewardship.

Ternary Reed-Solomon codes [PDF]

open access: yes, 1983
Ternary Reed-Solomon codes and a technique for encoding and decoding these special codes have been investigated. The algebraic theory of finite fields is used to discuss cyclic codes and thus introduce Bose-Chaudhuri-Hocquenghem codes, a special case of ...

How to see the forest despite the trees

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract One of the major starting points of discrete optimization is the theorem of Nash‐Williams and Tutte on the existence of k$k$ disjoint spanning trees of a graph, along with its counterpart on the existence of k$k$ forests covering all edges of the graph.

RS + LDPC-Staircase Codes for the Erasure Channel: Standards, Usage and Performance [PDF]

open access: yes, 2013
Application-Level Forward Erasure Correction (AL-FEC) codes are a key element of telecommunication systems. They are used to recover from packet losses when retransmission are not feasible and to optimize the large scale distribution of contents. In this

Robust Reed Solomon Coded MPSK Modulation

open access: yesJournal of ICT Research and Applications, 2014
In this paper, construction of partitioned Reed Solomon coded modulation (RSCM), which is robust for the additive white Gaussian noise channel and a Rayleigh fading channel, is investigated.

Positive Reframing of Psychosis Risk Reduces Social Stigma and Desire for Social Distance Among Adolescents: Moderating Roles of Prodromal Experiences, Sex, and Culture

open access: yesEarly Intervention in Psychiatry, Volume 20, Issue 7, July 2026.
ABSTRACT Background and Aims Communication about the at‐risk mental state may shape not only clinical understanding but also peer‐directed social evaluations. Prior work from our group has shown that positively reframing psychosis‐risk feedback reduces perceived emotional harm and clinician stigma.

On sharing secrets and Reed-Solomon codes

open access: yes, 1981
Shamir's scheme for sharing secrets is closely related to Reed-Solomon coding schemes. Decoding algorithms for Reed-Solomon codes provide extensions and generalizations of Shamir's method.
