Learning SAR-to-Optical Image Translation via Diffusion Models With Color Memory

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar (SAR) and optical sensing are two important means of Earth observation. SAR-to-optical image translation (S2OIT) can integrate the advantages of both and assist SAR image interpretation under all-day and all-weather conditions ...

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

Molecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

The Use of Optical Methods in the Analysis of the Areas with Stress Concentration

Journal of Mechanical Engineering, 2018
Anchoring parts of technical systems are often damaged due to the heavy forces acting on these systems during their operation. For that reason, various modifications are suggested and created on the anchoring screws, which should help to reduce the ...

Optical Correlator based Image Classifier

JSAP-OSA Joint Symposia 2018, 2018
In data recognition systems with large capacity databases, it is very important to improve the speed of the identification process. Recently, a system with dedicated hardware based on field-programmable gate array was proposed for speeding up this operation [1], and there is a high expectation for further high-speed verification.

Measurements of the Beam-Wave Fluctuations over a 142-km Atmospheric Path [PDF]

, 2006
An optical link has been established between the Canary Islands La Palma and Tenerife. A 1064-nm transmitting laser was located on La Palma whereas a BPSK communication receiver and measurement instruments were installed in ESA's OGS on Tenerife.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Development of a Low-cost Digital Image Correlation System to Evaluate the Behavior of Polymers at Large Deformation

Chemical Engineering Transactions, 2019
Among the main optical methods digital image correlation (DIC) can be highlighted. Although DIC development is relatively recent, the advantages offered by this method make it equally competitive with other classical optical techniques that suffer from ...

Flow measurements in a blood-perfused collagen vessel using x-ray micro-particle image velocimetry. [PDF]

PLoS ONE, 2013
Blood-perfused tissue models are joining the emerging field of tumor engineering because they provide new avenues for modulation of the tumor microenvironment and preclinical evaluation of the therapeutic potential of new treatments. The characterization

Application of optical measurement techniques to high strain rate deformations in composite materials [PDF]

, 2010
Traditionally high strain rate material characterisations have been conducted using strain gauges and/or cross head displacements in servo-hydraulic test machines, and force transducers in split Hopkinson bar experiments.

Characterization of therapeutic antibodies targeting lymphatic and vascular resistance factor for the treatment of hypervascularized and highly metastatic cancers

Molecular Oncology, EarlyView.
LVRF (lymphatic and vascular resistance factor) is a VEGFA splice variant upregulated in response to anti‐angiogenic therapy that fosters tumor adaptation through enhanced vascularization, lymphangiogenesis, and metastatic dissemination. Targeting LVRF with fully human neutralizing antibodies disrupts these processes and limits resistant tumor growth ...
