Multimodal Investigation of Angiogenesis and Its Prevention by Small Compounds in a Zebrafish Cancer Model

open access: yesAdvanced Science, EarlyView.
A combined optical coherence tomography angiography and fluorescence imaging approach assesses tumor angiogenesis and drug effects in a novel zebrafish cancer model. By analyzing 3D vasculature data, the two imaging methods complement each other to quantify blood flow, vessel structure, and drug efficacy.

New periodic variable stars coincident with ROSAT sources discovered using SuperWASP [PDF]

open access: yes, 2007
We present optical lightcurves of 428 periodic variable stars coincident with ROSAT X-ray sources, detected using the first run of the SuperWASP photometric survey. Only 68 of these were previously recognised as periodic variables.

K2 DISCOVERY OF YOUNG ECLIPSING BINARIES IN UPPER SCORPIUS: DIRECT MASS AND RADIUS DETERMINATIONS FOR THE LOWEST MASS STARS AND INITIAL CHARACTERIZATION OF AN ECLIPSING BROWN DWARF BINARY [PDF]

open access: yes, 2015
We report the discovery of three low-mass double-lined eclipsing binaries in the pre-main sequence Upper Scorpius association, revealed by K2 photometric monitoring of the region over ∼78 days. The orbital periods of all three systems are , M 2 = 0.1076

Mechanical Forces Guide Axon Growth through the Nigrostriatal Pathway in an Organotypic Model

open access: yesAdvanced Science, EarlyView.
Nano‐pulling is a magnetic nanoparticle‐based technology for guiding and promoting the axon growth of induced pluripotent stem cell‐derived dopaminergic neurospheres in vitro or neural progenitors transplanted in the brain tissue. Fine control of axon guidance is essential for reconstructing neural networks and restoring functional connectivity in the ...

The first CCD photometric study of the open cluster NGC 2126

open access: yes, 2003
We present the first CCD photometric observations of the northern open cluster NGC 2126. Data were taken on eight nights in February and December 2002 with a total time span of ~57 hours.

KM UMa: An Active Short-period Detached Eclipsing Binary in a Hierarchical Quadruple System

open access: yesThe Astrophysical Journal
The first detailed photometric and spectroscopic analysis of the G-type eclipsing binary KM UMa is presented, which indicates that the system is a short-period detached eclipsing binary.

ECLIPSING BINARY STARS : LIGHT CURVE MODELS AND SOFTWARE

open access: yesOdessa 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 ...

Catalytic Hairpin Assembly‐Propelled Weak‐Inputs‐Strong‐Outputs (CP‐WISO) DNA Logic Nanodevices with Orthogonal Design and Contrary Logic Responses

open access: yesAdvanced Science, EarlyView.
Catalytic hairpin assembly‐propelled weak‐inputs‐strong‐outputs (CP‐WISO) DNA logic nanodevices with orthogonal design and contrary logic responses are innovatively fabricated. Moreover, the even and odd parity generators/checkers for ensuring normal molecular data transmission, and the logic‐programmed miRNA biosensors with ratiometric fluorescent ...

Testing convection in stellar models using detached eclipsing binaries [PDF]

open access: yes, 2006
The fundamental properties of detached eclipsing binary stars can be measured very accurately, which could make them important objects for constraining the treatment of convection in theoretical stellar models.

TESS Light Curve of the Interacting Binary W Serpentis

open access: yesThe Astronomical Journal
The unusal light curve of the massive eclipsing binary W Ser was recently observed with high S/N and fast cadence by the NASA TESS mission. The TESS light curve records two eclipses and relatively fast variations outside of the eclipses.
