Optical Maser Emission from Trivalent Praseodymium in Calcium Tungstate [PDF]

, 1962
Coherent emission at 1.047 µ from trivalent praseodymium in calcium tungstate was observed. This emission coincides with strong infrared fluorescence at the same wavelength and was found to be stimulated mostly by absorption of blue light by the 3P0, 3P1,

The margin is where everything starts and everything ends . A. Dasilva O. Speaks to the country through Rádio Caos

Travessias, 2020
In the mid-1980s, Porto began to open to the cultural, musical, and aesthetic change announced by (post)-modernism. Resistance - and the search for the new - also began to make itself felt through radio programmes, fanzines, concerts, and bulletins ...

Propagation and stability of optical pulses in a diffractive dispersive non-linear medium [PDF]

, 1992
Propagation and stability of light pulses under the combined influence of the optical Kerr effect, dispersion and diffraction are investigated by adopting a variational procedure. In particular, it is found that 'light bullets', i.e.

A 3D Bioprinted Spheroid‐Laden dECM‐Enriched Osteosarcoma Model for Enhanced Drug Testing and Therapeutic Discovery

Advanced Healthcare Materials, EarlyView.
A 3D biomimetic OS model was developed by bioprinting an OS‐cell‐derived dECM‐enriched bioink with OS spheroids incorporated. The model showed upregulation of known OS prognostic markers and increased resistance to doxorubicin, compared to 2D cultures and scaffold‐free spheroids, making this a more clinically relevant platform for drug discovery ...

Light Stability of Laser‐Assisted Glass Encapsulated Perovskite Solar Cells under Different Atmospheres

Advanced Energy Materials, EarlyView.
This study presents a laser‐assisted glass‐frit encapsulation method for perovskite solar cells, comparing air‐, nitrogen‐, and CO2‐filled cavities. Results show that excluding oxygen and moisture significantly improves stability under illumination. The findings reveal the critical role of trapped gases in degradation, providing a pathway to durable ...

Impact of Recanalization on Liver Hypertrophy after Portal Vein Embolization and the Role of Re‐Embolization

Annals of Gastroenterological Surgery, EarlyView.
This retrospective study of 249 patients undergoing hepatectomy after right portal vein embolization (PVE) demonstrated that major recanalization–defined as recanalization more than one segment within the embolized liver–was associated with impaired regeneration of the future liver remnant (FLR).
