The determination of par levels from absorption coefficient profiles at 490 nm

open access: yesCiencias Marinas, 1999
A model is presented that allows the prediction of percent photosynthetically available radiation (PAR) levels from measured profiles of the absorption coefficient at 490 nm in the Gulf of California. Percent PAR levels depend on the diffuse attenuation

Early Versus Late Recurrence in Olfactory Neuroblastoma: A Multi‐Institutional Analysis of Predictive Risk Factors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory neuroblastoma (ONB) exhibits variable recurrence patterns, with significant late recurrences occurring years after treatment. We investigated cutoff periods to define late recurrence and identified predictors that distinguish patients at risk of late recurrence from those considered cured.

Atmospheric input and concentration of dissolved iron in the surface layer of the Gulf of California

open access: yesCiencias Marinas, 2009
A survey was conducted to determine the atmospheric input of particulate iron (Fep) and the factors and processes controlling the concentration and distribution of dissolved iron (Fed) in surface water (200 m) of the central Gulf of California ...

Scaffold‐Free Living Cellular Structure With Omnidirectional Architectures

open access: yesAdvanced NanoBiomed Research, EarlyView.
Hydrogel lumen confinement enables the direct formation of mechanically stable, scaffold‐free cellular filaments under entirely aqueous, phototoxicity‐free conditions. These processable living building blocks support omnidirectional assembly into complex three‐dimensional architectures, providing a simple and versatile platform for scaffold‐free ...
