Single-shot observation of optical rogue waves in integrable turbulence using time microscopy

open access: yesNature Communications, 2016
A rogue wave is an unexpected oscillation of large amplitude and is an example of the spontaneous formation of a coherent structure out of disorder. Here, the authors develop an experimental strategy that can provide snapshots in time and thus record the

Modeling of $\hbox{As}_{2}\hbox{S}_{3}$ Raman Fiber Lasers Operating in the Mid-Infrared

open access: yesIEEE Photonics Journal, 2013
A numerical study of As2S3 Raman fiber lasers is carried out to show their potential for the entire coverage of the 3-4-μm spectral band. Experimental results are first obtained from such a laser operated under controlled conditions in order to ...

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Targeting RAGE with Nanobodies for Molecular Imaging of Cancers and Alzheimer's Disease

open access: yesAdvanced Biology, EarlyView.
RAGE‐specific nanobodies were isolated via phage display and characterized by ELISA, cell ELISA, and SPR. In vivo imaging in renal carcinoma and Alzheimer's disease mouse models demonstrated that NbF8, the highest‐affinity clone, selectively targeted RAGE‐overexpressing tumors and brain tissues, highlighting its potential as a molecular imaging agent ...

3D In Vitro Models of Breast Cancer: Current Challenges and Future Prospects Toward Recapitulating the Microenvironment and Mimicking Key Processes

open access: yesAdvanced Biology, EarlyView.
In vitro cancer models are advantageous for studying important processes such as tumorigenesis, cancer growth, invasion, and metastasis. The complexity and biological relevance increase depending on the model structure, organization, and composition of materials and cells.

Plasma Processing with Fluorine Chemistry for Modification of Surfaces Wettability

open access: yesMolecules, 2016
Using plasma in conjunction with fluorinated compounds is widely encountered in material processing. We discuss several plasma techniques for surface fluorination: deposition of fluorocarbon thin films either by magnetron sputtering of ...

Laser Accelerators [PDF]

open access: yesIEEE Transactions on Nuclear Science, 1983
Laser accelerators may be conveniently characterized, by their mode of operation, into media, far-field, and near-field accelerators. The first category--media accelerators--include the Inverse Cherenkov Effect Accelerator, the Plasma Focus Accelerator, and the Beat Wave Accelerator (BWA).

Modelling Atherosclerotic Plaque Cap Mechanics: Microcalcifications Reduce Mechanical Properties in Mesenchymal Stromal Cell‐Based Model

open access: yesAdvanced Biology, EarlyView.
This study develops a tissue‐engineered model of the atherosclerotic cap using human mesenchymal stromal cells (MSCs). After 2 weeks of culture to produce a collagenous matrix, a mineralizing medium induces microcalcifications over 4 weeks. These constructs, imaged with second harmonic generation microscopy, lead to reduced ultimate stress at rupture ...
