At the eighth week of human embryonic development, 3D transparent imaging enables clear visualization of the outflow tract's morphological features, revealing its anatomical components in detail. Abstract The ductus arteriosus (DA) is a critical fetal vascular structure that shunts blood from the pulmonary artery to the aorta, bypassing the non ...

Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...

Optimization of photobiomodulation therapy for spinal cord injury: A review
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

This study presents a novel one‐step femtosecond laser modification technique for fabricating high‐quality periodic metasurfaces on lithium niobate thin films without surface damage and scattering centers. Under oblique incidence at 1030 nm, a 4.75‐fold enhancement in second‐harmonic generation efficiency is achieved through complementary mechanisms ...
