A 10b multibit-per-stage pipelined ADC incorporating merged-capacitor switching (MCS) technique achieves better than 53 dB SNDR at 120 MSample/s and 54 dB SNDR and 68 dB SFDR for input frequencies up to Nyquist at 100 MSample/s. The measured DNL and INL are f0.40 LSB and f0.48 LSB, respectively. The ADC fabricated in a 0.25 pm CMOS occupies 3.6 mm2 active die area and consumes 208 mW under a 2....

We obtain a static spherically symmetric wormhole solution due to the vacuum expectation value (vev) of Kalb–Ramond field. The is background tensor field which produces local Lorentz symmetry breaking (LSB) spacetime. Considering non-minimal coupling between and Ricci tensor, we found an exact traversable sustained by matter sources with negative isotropic pressure. source satisfies energy cond...

I study the VLA HI survey of HII galaxies by Taylor et al. (1995, ApJS, 99, 427; 1996, ApJS, 102, 189) and the VLA HI survey of low surface brightness (LSB) dwarf galaxies by Taylor et al. (1996, in press) to investigate the role of galaxy interactions in triggering the bursts of massive star formation seen in HII galaxies. Comparing the two surveys, I find that HII galaxies have companions mor...

Human pluripotent stem cells (PSCs) are a promising source of cells for applications in regenerativemedicine.Directed differentiation of PSCs into specialized cells such as spinal motoneurons or midbrain dopamine (DA) neurons has been achieved. However, the effective use of PSCs for cell therapy has lagged behind.Whereasmouse PSCderived DA neurons have shown efficacy in models of Parkinson’s di...

Digital watermarking technology is increasingly used to protect copyright and demonstrate ownership of digital multimedia (such as text, music, photos, videos). In order safeguard intellectual property rights rules for multimedia, this project suggests a text watermark algorithm. The process hiding little or grayscale images the main focus, though. masking in high-color high-density area block ...

This thesis presents a new multiple-valued encoder with re-configurable radix. The proposed circuits utilize serial cyclic D/A conversion and semi floatinggate (SFG) inverters for compact design and a high functional capacity per device. A re-configurable radix is not supported by existing SFG inverter based multiple-valued encoders which make use of parallel binary weight D/A conversion. The s...

We propose that the giant HI ring recently discovered by HIPASS for S0 galaxy NGC 1533 is formed by unequal-mass merging between gas-rich LSB (low surface brightness: “ghost”) galaxies and HSB disks. The NGC 1533 progenitor HSB spiral is transformed into a barred S0 during merging and the outer HI gas disk of the LSB is transformed into the giant HI ring. We also discuss two different possibili...

Steganography is the process of embedding data into a media form such as image, voice, and video. The major methods used for data hiding are the frequency domain and the spatial domain. In the frequency domain, the secret data bits are inserted into the coefficients of the image pixel's frequency representation such as Discrete Cosine Transform (DCT) , Discrete Fourier Transform (DFT) and Discr...
