Photometrical observations and shape modeling of space debris in medium Earth orbits

Solar-Terrestrial Physics
The circular medium Earth orbits with a period of about half a day in the inclination range from 50° to 70° are used by various global navigation satellite systems (GNSS), such as GLONASS, GPS, Beidou, Galileo.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

TLW: A Real-Time Light Curve Classification Algorithm for Transients Based on Machine Learning

Universe
The real-time light curve classification of transients is helpful in searching for rare transients. We propose a new algorithm based on machine learning, namely the Temporary Convective Network and Light Gradient Boosting Machine Combined with Weight ...

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Predicting Variable Star Light Curves [PDF]

International Astronomical Union Colloquium, 1993
AbstractI present a new method to test determinism, in particular the nonlinear behavior, in observed time series of pulsating stars, based on a recent prediction method which exploits the dynamical system theory. A method for filling gaps in data has thereby been constructed.

The Light Curve Analysis of AW Cam [PDF]

Journal of Astronomy and Space Sciences, 1995
The α Lyrae-type eclipsing binary AW Cam was observed photoelectrically in three wavelength regions. The obtained UBV light curves of AW Cam were analyzed with two separate modes (mode 2 for detached systems and mode 5 for semi-detached ones) of the ...

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 ...

Photoelectic BV Light Curves of Algol and the Interpretations of the Light Curves

Journal of Astronomy and Space Sciences, 1985
Standardized B and V photoelectric light curves of Algol are made with the observations obtained during 1982-84 with the 40-cm and the 61-cm reflectors of Yonsei University Observatory. These light curves show asymmetry between ascending and descending shoulders.

Conformal holography with curved light sheets

Optics Express
Projecting images onto arbitrary curved surfaces is a sought-after goal in computer-generated holography applications. However, achieving high axial resolution with a low level of cross-talk using a single computer-generated hologram is still challenging. Here we propose and demonstrate a new type of holographic technique that projects conformal images

ECLIPSING BINARY STARS : LIGHT CURVE MODELS AND SOFTWARE

Odessa Astronomical Publications, 2017
The importance of studying Eclipsing Binary Stars for the determination of fundamental stellar data is sketched. The eclipsing binaries, originally classified phenomenologically, are now understood on the basis of much firmer physics and the improved ...
