The Kepler Mission is searching for Earth-size planets orbiting solar-like stars by simultaneously observing >160,000 to detect sequences of transit events in the photometric light curves. Combined Differential Photometric Precision (CDPP) metric that defines ease with which these weak terrestrial signatures can be detected. An understanding CDPP invaluable evaluating completeness survey and inferring underlying planet population. This paper describes how calculated, introduces tables rms on...
We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1–Q8). From an initial list 13,400 threshold crossing events, 480 new host stars are identified from their flux time series as consistent with hosting transiting planets. Potential transit signals subjected further analysis using pixel-level data, which allows background eclipsing binaries be through small image position shifts during transit. also re-evaluate Objects...
PVA hydrogels with high strength and toughness are fabricated by dual physical chemical cross-linking. The best comprehensive mechanical properties can be achieved reaction at room temperature followed freeze-thaw annealing treatment. Besides, the of hydrogel increased first then decreased increase molecular weight or mass fraction. By changing solvent, could also effectively adjusted. Therefore, influences various factors on obtained.
The discovery of superconductivity with a critical temperature about 80 K in La3Ni2O7 single crystals under pressure has received enormous attention. is not superconducting ambient but exhibits transition at T ∗ ≃ 115 K. Understanding the electronic correlations and charge dynamics an important step towards origin other instabilities. Here, our optical study shows that features strong which significantly reduce electron's kinetic energy place this system proximity Mott phase. low-frequency...
Abstract Crystal structure exerts dominant influence on the microwave dielectric performance enabling satisfying demands for 5G communication system. In this study, Ti‐doped Li 3 Mg 2 Nb 1‐x Ti x O 6‐x/2 ( = 0.0‐0.1) ceramics were prepared by solid‐state reaction procedure. refinement and microstructure analysis indicate pure phase with orthorhombic homogeneous grain size (~14 μm). The relative permittivity was affected density, cell volume, polarizability. Q × f value dominated Nb‐O bond...
Highly conductive polymer composites (CPCs) with excellent mechanical flexibility are ideal materials for designing electromagnetic interference (EMI) shielding materials, which can be used the protection of flexible electronic devices. It is extremely urgent to fabricate ultra-strong EMI CPCs efficient networks.
