Morphological and Transcriptome Analysis of the Near-Threatened Orchid Habenaria radiata with Petals Shaped Like a Flying White Bird [PDF]
PlantsOrchids have evolved flowers with unique morphologies through coevolution with pollinators, such as insects. Among the floral organs, the lip (labellum), one of the three petals, exhibits a distinctive shape and plays a crucial role in attracting ...

Bio-Inspired Blade Serrations: A Review on Owl-Based Strategies for Aeroacoustic Noise Mitigation [PDF]
BiomimeticsThe increasing deployment of wind energy has brought renewed attention to aeroacoustic noise generated by wind turbine blades, where broadband noise is primarily associated with vortex shedding at the trailing edge (TE) and leading edge (LE) of airfoils.

Serrated Polyps and Serrated Polyposis Syndrome [PDF]
Clinics in Colon and Rectal Surgery, 2016 AbstractColorectal serrated polyps are intermediate lesions in the serrated neoplastic pathway, which account for up to 30% of colorectal cancers. This pathway is biologically distinct from the adenoma-to-carcinoma sequence, with associated cancers exhibiting mutations in the BRAF oncogene, DNA promoter hypermethylation, and microsatellite instability.

Antigenic properties of serration bacteriophages [PDF]
BIO Web of Conferences, 2022 The genus Serratia is one of the poorly studied among enterobacteria, which explains the interest in these microorganisms and bacteriophages active towards these microorganisms. The aim of this work was to study the antigenic properties of bacteriophages

Wall-modeled large-eddy simulation of a trailing-edge serration–finlet configuration
AIP Advances, 2021 This paper proposes a novel trailing-edge treatment to reduce airfoil self-noise: a serration–finlet configuration. According to the current literature, while serrations are good at reducing low-frequency noise, finlets are able to significantly reduce ...
