Visual cortex (V1) exhibits two types of gamma oscillation: a well-characterized broadband (30-90Hz) rhythm, and a narrowband oscillation occurring at frequencies close to 60 Hz in mice. We investigated the source of narrowband gamma, the factors modulating its strength, and its relationship to broadband gamma. Narrowband and broadband gamma power were uncorrelated. Increasing visual contrast h...

The deep tissue penetration and submicron spatial resolution of multiphoton microscopy and the high detection efficiency and nanometer spectral resolution of a spectrograph were utilized to record spectral images of the intrinsic emission of mouse skin tissues. Autofluorescence from both cellular and extracellular structures, second-harmonic signal from collagen, and a narrowband emission relat...

Abstract Solar jets are ubiquitous phenomena in the solar atmosphere. They important mass and energy transport to upper atmosphere interplanetary space. Here, we report a detailed analysis of small-scale chromospheric jet with high-resolution He i 10830 Å TiO 7057 images observed by 1.6 m aperture Goode Telescope at Big Bear Observatory. The observation reveals finest dark threads inside rooted...

We present a unified theory for passive synthetic aperture imaging based on inverse scattering, estimation-detection theory and microlocal analysis. Passive synthetic aperture imaging uses sources of opportunity for illumination and moving receivers to measure scattered field. We consider passive airborne receivers that fly along arbitrary, but known, flight trajectories and static or mobile so...

Pyroelectric detectors are often broadband and require external filters for wavelength-specific applications. This paper reports a tunable, narrowband, lightweight pyroelectric infrared detector built upon flexible membrane of As2S3−Ag−P(VDF-TrFE) with subwavelength grating, which is capable both on-chip filtering photopyroelectric energy conversion. The top surface this hybrid corrugated As2S3...
