Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): baseline data from day surgery practice in the UK

open access: yesAnaesthesia, EarlyView.
Summary Introduction Most patients undergoing elective surgery in the UK are discharged from hospital on the same day. Despite this, there is a lack of UK patient‐centred outcome measures relating to quality of recovery, pain and analgesic use. The POPPY study was a UK‐wide prospective, observational study measuring short‐ and longer‐term patient ...

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): chronic post‐surgical pain prevalence and associations*

open access: yesAnaesthesia, EarlyView.
Summary Introduction Day‐case surgical activity is increasing in the UK yet there is a lack of data on the prevalence of chronic post‐surgical pain in this population. This study uses data from the POPPY study to estimate the prevalence of chronic post‐surgical pain after day‐case surgery, its relationship with quality of life and also explores ...

A fast method for blindly identifying Reed‐Solomon codes based on matrix analysis

open access: yesIET Communications, 2022
For the identification of Reed‐Solomon (RS) codes, the existing methods need to test the possible codeword length and the primitive polynomials exhaustively. Exhaustive search leads to high computational complexity.

Performance Analysis of the LDPC‐Coded Hybrid LQAM‐MPPM for UWOC Systems

open access: yesIET Optoelectronics, Volume 20, Issue 1, January/December 2026.
The effectiveness of LDPC codes in improving the performance of hybrid modulations is discussed, with coded 128‐QAM‐(12, 2) MPPM offering ~6.5 and 5.8 dB code gains at a BER of in strong and moderate turbulence, respectively. These results demonstrate the promise of hybrid modulation with LDPC as a robust and efficient modulation scheme for UWOC ...

DNA Barcoding Reveals Cryptic Diversity and Informs Conservation Priorities in Chinese Firmiana Species (Malvaceae) Using Genome Skimming Data DNA条形码揭示中国梧桐属 (锦葵科) 隐存多样性及保护优先级:来自基因组浅层测序数据的证据

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 569-583, December 2025.
Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

Syndrome spectrums of error orbits in RS-codes

open access: yesСистемный анализ и прикладная информатика, 2020
This article is devoted to the research of the properties of syndromes of errors in Reed-Solomon codes. RS-codes are built on non-binary alphabets. So, unlike BCH-codes, RS-codes contain an extremely large variety of correctable errors.
