Synthetic Aperture Radar (SAR) target detection and identification technology is one of the choke points for SAR practical application, the key of which is effective feature extraction. In terms of high resolution SAR image, target identification performance can be improved if contour feature of target, one of main geometric structures, can be detected accurately. Therefore a method was propose...

Superconducting nanowire avalanche single-photon detectors (SNAPs) with n parallel nanowires are advantageous over single-nanowire detectors because their output signal amplitude scales linearly with n. However, the SNAP architecture has not been viably demonstrated for n > 4. To increase n for larger signal amplification, we designed a multi-stage, successive-avalanche architecture which used ...

This paper presents the analytical solution in time domain for the ideal single-ended Class-E Power Amplifier (PA). Based on the analytical solution a coherent non-iterative procedure for choosing the circuit parameters is presented for ClassE PA’s with arbitrary duty-cycle and finite dc-feed inductance (e.g. continuously ranging from Class-E with small finite drain inductance to Class-E with R...

in the culture can make us choke during tests of ability. . . . The power of stereotypes, scientists had long figured, lay in their ability to change the behavior of the person holding the stereotype. . . . But five years ago, Stanford University psychologist Claude Steele showed something else: It is the targets of a stereotype whose behavior is most powerfully affected by it. A stereotype tha...

The elderly who is confined to bed or demented may choke if their cerebrum is not sufficiently aroused while eating. Therefore, this study focused on determining if hygienic care of the hands and fingers would have a biologically stimulative effect and on verifying whether using a warm cloth or warm water was more effective for cerebral activation. The results suggest that when assisting the el...
