“Super-deblended” Dust Emission in Galaxies. II. Far-IR to (Sub)millimeter Photometry and High-redshift Galaxy Candidates in the Full COSMOS Field [PDF]

open access: yesAstrophysical Journal, 2018
We present a “super-deblended” far-infrared (FIR) to (sub)millimeter photometric catalog in the Cosmic Evolution Survey (COSMOS), prepared with the method recently developed by Liu et al., with key adaptations.

Multicolour photometry for exoplanet candidate validation [PDF]

open access: yesAstronomy & Astrophysics, 2019
Context. The TESS and PLATO missions are expected to find vast numbers of new transiting planet candidates. However, only a fraction of these candidates will be legitimate planets, and the candidate validation will require a significant amount of follow ...

A Cubesat Payload for Exoplanet Detection

open access: yesSensors, 2017
The search for undiscovered planets outside the solar system is a scientific topic that is rapidly spreading into the astrophysical and engineering communities. In this framework, the design of an innovative payload to detect exoplanets from a nano-sized

Delta Opioid Receptors within the Cortico‐Thalamic Circuitry Underlie Hyperactivity Induced by High‐Dose Morphine

open access: yesAdvanced Science, EarlyView.
Morphine activates the excitatory cingulate cortex–intermediate rostrocaudal division of zona incerta (Cg‐ZIm) pathway to drive hyperlocomotion in mice. Inhibiting the Cg‐ZIm pathway attenuates both acute and chronic morphine‐induced hyperlocomotion, while its activation mimics morphine's motor effects.

An Optimized Colorimetric Readout Method for Lateral Flow Immunoassays

open access: yesSensors, 2018
Despite its broad penetration of various markets, the quantitative lateral flow immunoassay (LFIA) suffers from sensitivity issues in some cases. To solve this problem, an optimized colorimetric readout method for LFIA quantification is proposed in this ...

NORAD TLE Type Orbit Determination of LEO Satellites Using GPS Navigation Solutions [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2002
NORAD Two Line Elements (TLE) are widely used for the increasing number of small satellite mission operations and analysis. However, due to the irregular periodicity of generation of the NORAD TLE, a new TLE that is independent of NORAD is required.

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

TSI modeling: A comparison of ground-based Ca II K-line data with space-based UV images from the SDO/AIA instrument

open access: yesJournal of Space Weather and Space Climate
The Total Solar Irradiance (TSI) is an important input for the Earth’s climate. To describe the competing contributions of sunspots and faculae on irradiance variability, the San Fernando Observatory (SFO) irradiance model has two components: One ...

THE RESEARCH OF VARIATION OF THE PERIOD AND PRECESSION OF THE ROTATION AXIS OF EGS (AJISAI) SATELLITE BY USING PHOTOMETRIC MEASUREMENT

open access: yesOdessa Astronomical Publications, 2014
The light curves of EGS Ajisai with temporal resolution of 20 ms referred to the time scale UTC (GPS) with an error of at most 0.1 ms were obtained. The observed flashes are produced when the mirrors which cover the spinning satellite’s surface reflect ...
