The interest in quantum dot sensitized solar cells (QDSSC), which has theoretically proved to have up 44% energy conversion efficiency recent years, is growing rapidly. Although it high value, PCE obtained studies with QDSSCs far from these values. This situation shows that there are many difficulties be solved QDSSC technology. One of the main challenges technology irradiated load recombinatio...
Abstract We report both experimentally and numerically that an acoustic suppressed topological refraction is realized by two kagome-lattice valley sonic crystals (VSCs). By simply rotating triangle rods in the VSCs, Hall phase transitions can be obtained. In a designed waveguide composed of VSCs with distinct phases, types edge states observed domain wall. Furthermore, support sound, which aris...
Lifetime-broadening-suppressed (LBS) state-selective XAFS spectra can be deduced by analyzing resonant inelastic x-ray scattering (RIXS) in terms of formulae derived from the Kramers-Heisenberg equation. By a combination of third-generation synchrotron sources and spectrometers equipped with a large acceptance as well as high-resolution analyzers, high-quality RIXS data to extract LBS selective...
We summerize the status of factorization hypothesis in the color-suppressed B meson decays : B → J/ψK (*). We present the general formalism for decay rates and polarization fractions with considering all possible non-factorizable contributions which also include the color-octet contributions, and a new factorization scheme comes appear when the universality is exist : χ F 1 = χ A1 = χ A2 = χ V ...
BACKGROUND The pathological change of kidney in diabetic nephropathy is represented hypertrophy, inflammation, and renal fibrosis. Oryeongsan, traditional oriental herbal formula, is widely used for the treatment of nephrosis, dropsy, and uremia. This study was examined whether Oryeongsan attenuate high-glucose (HG)-promoted rat mesangial cell fibrosis and matrix accumulation, major features of...
We studied perceptual learning in motion discrimination when the brain's middle temporal area (MT/V5) was functionally suppressed. This was achieved by using the "paired-dots" motion stimulus where the two dots in a pair always move in counter-phase over a short distance [J. Neurosci. 14 (1994) 7357]. The motion directional signal of the stimulus is therefore always 0 on average. As a result, t...
BACKGROUND Expression of the tumor suppressor p16(INK4a) increases during aging and replicative senescence. METHODOLOGY/PRINCIPAL FINDINGS Here, we report that the microRNA miR-24 suppresses p16 expression in human diploid fibroblasts and cervical carcinoma cells. Increased p16 expression with replicative senescence was associated with decreased levels of miR-24, a microRNA that was predicted...
