Cosmic dust investigation by optical tweezers for space exploration

, 2021
We trap individual cosmic dust particles by Raman-Tweezers to identify their compositions and to characterize their response to optical forces without any substrate ef- fects, documenting the high potential of this novel technique for space ...

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 ...

Optical Investigation of ZnS/GaAs and CuGaS2/GaP Systems

East European Journal of Physics
ZnS and CuGaS2 are materials with a wide range of applications in modern optoelectronics. These materials are used for IR windows as well as lenses in the thermal band, where multispectral maximum transmission and lowest absorption are required ...

Wavelength-diversity transmission for fading mitigation in the atmospheric optical communication channel [PDF]

, 2006
Mitigation of index of refraction turbulence (IRT) effects is crucial in long-range atmospheric communication links. Diversity-transmission is one favorable way for fading compensation.

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Optical investigation of nanophotonic lithium niobate-based optical waveguide

Applied Physics B, 2015
Lithium niobate (LiNbO3) nanophotonics are prepared on quartz substrate by sol–gel method. They have been deposited with different molarity concentrations and annealed at 500 °C. These samples are characterized and analyzed by scanning electron microscope, atomic force microscopy, X-ray diffraction and ultraviolet–visible.

Numerical simulations of beam propagation through optical turbulence for high-altitude platform crosslinks [PDF]

, 2004
In this paper we introduce a simulation method for modelling clear-air atmospheric turbulence effects for long horizontal stratospheric paths. Divergence angles of several hundred microradians in combination with link distances up to 800 km require to ...

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Investigation of 2H/1T/1T′ phase MoS2 optical nonlinearity

Discover Nano
2H and 1T/1T′ molybdenum disulfide (MoS2) are typical phases that can be found in crystalline and thin film materials. In this work, by controlling the atmosphere during thin film chemical vapor deposition, 2H or 1T/1T′ phase MoS2 are grown separately ...
