To investigate the effect of face inversion and thatcherization (eye inversion) on temporal processing stages of facial information, single neuron activities in the temporal cortex (area TE) of two rhesus monkeys were recorded. Test stimuli were colored pictures of monkey faces (four with four different expressions), human faces (three with four different expressions), and geometric shapes. Mod...
In this work, we exploit the idea of composite pulses to achieve robust population inversion in a three-level quantum system. The scheme is based on modulation coupling strength, while other physical parameters remain unchanged. sequence designed by vanishing high-order error terms, and can compensate systematic errors any desired order. particular, keeps good performance under disturbance wave...
We present a blueprint for maser with single three-level transmon superconducting artificial atom. The system can be pumped coherently via two-photon process, and to achieve high population inversion, the relaxation rate of metastable state is increased an auxiliary low-$Q$ cavity coupled transition between excited states. show numerically that such operate both in intermediate-coupling regime ...
15 16 Running title: Gene exchange shaping variation 17 Word count (main text): 5709 18 19 2 Gene flow (defined as allele exchange between populations) and gene flux (defined as 20 allele exchange during meiosis in heterokaryotypic females) are important factors 21 decreasing genetic differentiation between populations and inversions. Many 22 chromosomal inversions are under strong selection an...
