THE OVERVIEW OF THE PLANETARY ATMOSPHERIC SPECTRAL TELESCOPE (PAST) IN THE SCIENTIFIC EXPERIMENTAL SYSTEM IN NEAR-SPACE (SENSE)

To investigate mass transport and energy dissipation in space environments for solar system planet, a balloon-borne planetary atmospheric spectral telescope (PAST) is designed with 0.8-m aperture in spectral range from 280 nm to 680&...

Enlarging Rainfall Area of Tropical Cyclones by Atmospheric Aerosols

Abstract The size of a tropical cyclone (TC), measured by the area of either rainfall or wind, is an important indicator for the potential damage by TC. Modeling studies suggested that aerosols tend to enhance rainfall in the outer rainband...

Validation of Sentinel-2 (MSI) and Sentinel-3 (OLCI) Water Quality Products in Turbid Estuaries Using Fixed Monitoring Stations

It is common in estuarine waters to place fixed monitoring stations, with the advantages of easy maintenance and continuous measurements. These two features make fixed monitoring stations indispensable for understanding the optical complexi...

Nanosensor Applications in Plant Science

Plant science is a major research topic addressing some of the most important global challenges we face today, including energy and food security. Plant science has a role in the production of staple foods and materials, as well as roles in...

Contrast Sensitivity Is Associated With Chorioretinal Thickness and Vascular Density of Eyes in Simple Early-Stage High Myopia

ObjectiveTo evaluate the contrast sensitivity function (CSF), chorioretinal thickness and vascular density as well as their relationships in subjects with simple early-stage high myopia.MethodsEighty-one young subjects were enrolled in this...

Involvement of two uptake mechanisms of gold and iron oxide nanoparticles in a co-exposure scenario using mouse macrophages

Little is known about the simultaneous uptake of different engineered nanoparticle types, as it can be expected in our daily life. In order to test such co-exposure effects, murine macrophages (J774A.1 cell line) were incubated with gold (A...

Synthesis and properties of fluorene based small molecule acceptors containing aromatic malononitrile functionalities

Four novel small molecule acceptors (SMA) with fluorene-based cores were synthesized with terminal phenyl, thienyl, and furyl malononitrile groups in good yields. The products were obtained from a two-step reaction of 2,2′-(9,9-dioctyl-9H-f...

TEMPERATURE OF SLIDING SURFACES OF INTERNAL COMBUSION ENGINES BY THE TEMPER COLORS OF WEAR PARTICLES

The present study examines the temper colors of the wear particles retained by the oil filter by optical microscope. The temperature of the sliding surfaces inside engines can be determined by the temper colors of the wear particles. Becaus...

All-dielectric metaoptics for the compact generation of double-ring perfect vector beams

Perfect vortices, whose ring profile is independent of the topological charge, play a key role in telecommunications and particle micro-manipulation. In this work, we report the compact generation of a new kind of double-ring perfect vortic...

The Structure of Micro-Variability in the WEBT BL Lacertae Observation

We present the results of an in-depth analysis of the Whole Earth Blazar Telescope (WEBT) micro-variability observations made during a campaign done in 2020 on the blazar BL Lacertae. The data consisted of 231 days of optical imaging and we...

Analytic NNLO QCD corrections to top quark pair production in electron-positron collisions

Abstract We present the analytic total cross section of top quark pair production in electron-positron annihilation at next-to-next-to-leading order (NNLO) in Quantum Chromodynamics (QCD). By utilizing the optical theorem, the NNLO correcti...

Investigation of dipole emission near a dielectric metasurface using a dual-tip scanning near-field optical microscope

A wide variety of near-field optical phenomena are described by the interaction of dipole radiation with a nanophotonic system. The electromagnetic field due to the dipole excitation is associated with the Green’s function. It is of great i...
