Bi-directional reflectance measurements of closely packed natural and prepared particulate surfaces
One of the most general ways to quantify the surface reflectance of a medium is by use of the bi-directional reflectance distribution function (BRDF) (Hapke, 1993).

Advanced Healthcare Materials, EarlyView.Packed hydrogel microfiber (PHM) materials consist of flexible and high aspect ratio hydrogel components that, as a bulk material, are simultaneously mechanically robust and dynamic. Cells cultured in or on PHM scaffolds can be influenced by topographical cues or interact with a dynamic environment that permits cell spreading and multicellular ...

Advanced Healthcare Materials, EarlyView.This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

Prediction of directional reflectance of a corn field under stress
, 1972 A vegetative canopy model concept is developed and used to calculate the directional spectral reflectance of a corn field under stress. The problem has been idealized by assuming that the canopy is represented in several layers of uniform but randomly ...

Retrieval of at-sensor irradiance using Incident Light Sensor (ILS)
, 2002 A number of aircraft sensors have the facility to measure spectral downwelling irradiance using a sensor mounted on the roof of the aircraft, but these data are rarely used for atmospheric correction.

Matrix Stiffness Directs Stemness Signatures in Breast Cancer
Advanced Healthcare Materials, EarlyView.We built lab‐grown breast cancer models to study how the stiffness of the tumor's surroundings influences cancer behavior. Softer environments encouraged more stem‐like, drug‐resistant cells, while stiffer ones kept cells more differentiated. These findings show that tissue mechanics drive cancer diversity and drug resistance, offering new insights for
