Information Design for Early‐Stage Dose‐Finding Trials

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT To enhance enrollment rates in early‐stage dose‐finding clinical trials, we propose an information design approach, where the clinical investigator (CI) commits to an information releasing mechanism (IRM) based on the treatment's uncertain efficacy and toxicity to encourage patients to participate in the trial.

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

open access: yesNordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Taxonomy of a novel and a new geographical record of Nigropunctata species (Pallidoperidiaceae) on Bambusa vulgaris from northern Thailand

open access: yesNordic Journal of Botany, EarlyView.
Nigropunctata is an understudied genus of bambusicolous fungi, and its diversity in Thailand remains poorly known. This study aimed to investigate species of Nigropunctata associated with bamboo in Thailand using morphological observations along with multi‐locus phylogenetic analyses of the internal transcribed spacer (ITS), large subunit (LSU), RNA ...

Taxonomy and phylogeny of the intercontinental disjunctive ferns: series Reniformia Adiantum

open access: yesNordic Journal of Botany, EarlyView.
There are disputed opinions about the three taxa of series Reniformia, namely A. nelumboides X.C.Zhang (A. reniforme var. sinense Y.X.Lin), A. reniforme var. reniforme, and A. reniforme var. asarifolium (Willd.) R. Sim, owing to their similar morphology but intercontinental disjunctive distribution and close lineage with the series Venusta (only ...

Mazus dabieshanensis sp. nov. (Mazaceae) from eastern China

open access: yesNordic Journal of Botany, EarlyView.
Mazus dabieshanensis, a newly described species endemic to the Dabieshan Mountains in eastern China, is illustrated and described. Molecular phylogenetic analyses based on nuclear and chloroplast DNA sequences consistently demonstrate that this new species forms a stable clade with other Mazus species characterized by a pubescent ovary. Morphologically,

Missed Nursing Care in Neonatal Intensive Care Units for Infants Experiencing or at Risk of Experiencing Substance Withdrawal

open access: yesResearch in Nursing &Health, EarlyView.
ABSTRACT Caring for infants experiencing or at risk of substance withdrawal often increases nursing workload and may contribute to missed nursing care (MNC). This study examined the relationship between infants' substance withdrawal status and the occurrence of MNC in neonatal intensive care units (NICUs). We conducted a secondary analysis of data from

Both density‐ and frequency‐dependent effects determine plant growth in a dune heath ecosystem

open access: yesOikos, EarlyView.
We tested the hypothesis that both density‐ and frequency‐dependent interactions play important roles in determining plant growth in a dune heath ecosystem at several levels of available nitrogen. Plant growth was measured using the pin‐point method in a five‐block experiment with four nitrogen levels.

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

open access: yesOikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it
