Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase

open access: yesChemBioChem, Volume 27, Issue 12, 26 June 2026.
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Remodeling Grounded Theory

open access: yesGrounded Theory Review: An International Journal, 2004
This paper outlines my concerns with Qualitative Data Analysis’ (QDA)numerous remodelings of Grounded Theory (GT) and the subsequent eroding impact. I cite several examples of the erosion and summarize essential elements of classic GT methodology.

Total Synthesis and Antimalarial Studies of Caelestines A–C

open access: yesChemMedChem, Volume 21, Issue 11, 15 June 2026.
Total synthesis of caelestines A–C (alkaloids from the Australian ascidian, Aplidium caelestis) was accomplished, constituting the first synthesis of caelestines B and C. Caelestines A–C, with five other novel quinolones, were assessed against Plasmodium falciparum 3D7 and Dd2. Caelestine B was found to be a selective antimalarial alkaloid. Caelestines

Making teaching an attractive profession: What are the challenges and opportunities for minority ethnic teachers in England?

open access: yesBritish Educational Research Journal, Volume 52, Issue 3, Page 1878-1897, June 2026.
Abstract This paper explores the challenges and opportunities surrounding the recruitment and retention of minority ethnic teachers in England. Drawing on interview data from 33 teachers and school leaders of diverse ethnic backgrounds, it investigates whether racialised barriers identified in earlier research have shifted in the current context of ...

Two-Stage Estimation for Ultrahigh Dimensional Sparse Quadratic Discriminant Analysis

open access: yesJournal of Mathematics
The conventional Quadratic Discriminant Analysis (QDA) encounters a significant hurdle due to parameter scaling complexities on the order of Op2, rendering it impractical for the analysis of high or ultrahigh dimensional data. This arises especially when

Application of the Permutation Entropy over the Heart Rate Variability for the Improvement of Electrocardiogram-based Sleep Breathing Pause Detection

open access: yesEntropy, 2015
In this paper the permutation entropy (PE) obtained from heart rate variability (HRV) is analyzed in a statistical model. In this model we also integrate other feature extraction techniques, the cepstrum coefficients derived from the same HRV and a set ...

Decoding Choroid Plexus Pathology in Alzheimer's Disease: A Longitudinal Radiomics Approach for Prodromal Identification and Risk Stratification

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
A machine learning model utilizing choroid plexus (CP) radiomics effectively distinguishes Alzheimer's disease (AD) from mild cognitive impairment (MCI) and predicts MCI‐to‐AD progression risk. After integration with clinical features, the model exhibits strong predictive performance. The CP radiomics features correlate significantly with cognitive and
