In addition to the higher concentration of receptors, there is also a higher ratio of ganglion and bipolar cells that “process” the input—nearly a 1-to-1 mapping of receptor to high-level cells, permitting high acuity. The other important aspect of the retina is how large the overall re...
The saddle-point spectrum analysis of the open bosonic Polyakov string in SO(N) 来自 World Scientific 喜欢 0 阅读量: 20 作者: LCL Botelho 摘要: In this paper, we investigate the role of the chiral anomaly in determining the spectrum at the saddle-point approximation D→-∞ of the recently...
although the two core phenotypes in social communication and behavior generally remain. The disorder occurs in roughly 1 in 100 children, with boys outnumbering girls by approximately 3–5 to 1 (Elsabbagh et al., 2012).ASDhas a very high burden of suffering because the associated difficulties ...

Moreover, at low doping levels a marked increase in the Fermi velocity is observed which is consistent with the logarithmic divergence expected due to the onset of many body effects close to the Dirac point. 展开 关键词: Ferrites microwave sintering electrical properties magnetic properties ...
The countries of origin of families with biallelic CM genotypes are highlighted in Fig.3. As expected, patients with homozygous variants are enriched in population bottlenecks where founder variants are prevalent (for example, Finland) and in countries of high consanguinity (Fig.3a–c). For recessi...
To a first order (single or weak scattering) approximation, the diffracted field F(x0, y0) generated by a plane wave travelling along the z-axis and recorded at a point z0 in the far field is given by (ignoring scaling) Fx0y0=∫∫fxyexp−i2πx0x/λz0exp−i2πy0y/λz0dxdy ...
high excitation intensity of 100 W/cm2, and the photoluminescenceexcitation spectrum, monitored at the energy of 1.0 eV (the lowest-energy first emission). It was possible to detect two clear resonances exactly at the same energy as those in the photoluminescence spectra. This represents direct ...
