Cassettes harboring luciferase reporter driven by Bombyx mori cytoplasmic actin gene promoter (A3) (671 bp) and B. mori nuclear polyhedrosis virus immediate-early promoter (IE-1) (580 bp) were transferred to the bacmid AcDeltaEGT to generate the recombinant Autographa californica nuclear polyhedrosis viruses, AcNPVA3Luc and AcNPVIELuc, respectively.… (More)
A cassette harboring luciferase reporter driven by Bombyx mori A3 promoter was transferred to the bacmid AcDeltaEGT to generate the recombinant virus AcNPVA3Luc (where Ac represents Autographa californica, NPV represents nucleopolyhedrovirus, and A3Luc represents the firefly luciferase reporter cassette driven by the A3 promoter). Recombinant baculovirus… (More)
Surface-enhanced Raman scattering (SERS) has attracted wide attention because it can enhance normally weak Raman signal by several orders of magnitude and facilitate the sensitive detection of molecules. Conventional SERS substrates are constructed by placing metal nanoparticles on a planar surface. Here we show that, if the planar surface was substituted… (More)
Preserving invaluable historic recordings has drawn some interest because the traditional record playback system wears out the record gradually. This paper presents a non-contact method to reproduce sound signal from gramophone records using 3D scene reconstruction of the micro-grooves cast on a record surface. Because of the unique shape of the… (More)
We report on four algorithms for recovering dense depth maps from long image sequences, where the camera motion is known a priori. All methods use a Kalman filter to integrate intensity derivatives or optical flow over time to increase accuracy.
Preserving historic recording on gramophone records is an important task because the traditional record play back system damages/wears out records eventually. We present an optical flow based method to reproduce the sound signal from gramophone records using 3 D robust scene reconstruction of the surface orientation of the walls of the grooves. The imaging… (More)
We present a non-contact optical flow based method to reproduce the sound signal from gramophone records using 3D robust scene reconstruction of the surface orientation of the walls of the grooves. The conversion of analogue data to digital data is an important task for the preservation of historic sound recordings. We digitally viewed the grooves of a… (More)
