Male genitalia, hierarchical homology, and the anatomy of the bullet ant (Paraponera clavata; Hymenoptera, Formicidae)

open access: yesJournal of Morphology, Volume 285, Issue 9, September 2024.
We present a multimodal anatomy of the male genitalia of the bullet ant, Paraponera clavata. Using this as a model system, we expand and refine on the 5‐category system of homology classification proposed by Meneganzin et al. (2024) and we present evidence supporting the penis‐coxopod theory of male genitalic homology in male insects. Abstract The male

Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches

open access: yesJournal of Extracellular Vesicles, Volume 13, Issue 2, February 2024.
Abstract Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year‐on‐year increase in the numbers of scientific ...

Fog resilient optical camera communication using wavelength division multiplexing.

open access: yesOptics Express
Maintaining reliable performance of optical camera communication (OCC) in low visibility scenarios, such as dense fog, is challenging due to light scattering and attenuation. Here, we present a side-emitting fiber-based OCC system that performs below the

Color-Shift Keying for Optical Camera Communication Using a Rolling Shutter Mode

open access: yesIEEE Photonics Journal, 2019
An optical camera communication (OCC) is a special type of a visible light communication that uses a complementary metal-oxide semiconductor as a receiver. However, it is difficult to apply a high-order modulation scheme to such communications because of
