—We address the problem of performing simultaneous analog-to-digital (A/D) conversion on multi-channel signals using a single A/D converter (ADC). Assuming that each input has an unknown sparse representation in known dictionaries, we find that multi-channel information can be sampled with a single ADC. The proposed ADC architecture consists of a mixed(More)
—This paper presents a simple but high performance architecture for multi-channel analog-to-digital conversion. Based on compressive sensing, only one SAR ADC is needed to convert multi-channel sparse inputs, leading to significant analog power saving and hardware saving. Moreover, it helps avoid problems occurring in conventional multi-channel ADCs such as(More)
OBJECTIVE Animals underwent combined general-epidural anesthesia (EGA) is reported to have better long-time outcome than general anesthesia (GA). This study aimed to make overall evaluation of the association between these two anesthetic techniques and prognosis of cancer patients undergoing surgery.

The objective of this work is to investigate the relationship between endo-β-mannanase and leaf abscission, and response to wounding in soybean (Glycine max). An endo-β-mannanase gene GmMAN1 was cloned from the abscission zone in petiole explants, and was heterologously expressed in E. coli. Polyclonal antibodies were raised against the fusion protein. The(More)
Software as a Service (SaaS) is a new software model for companies, which can provide them necessary software services based on a unique platform. In a general model of SaaS, the Independent Software Vendor (ISV) has a configurable and multi-tenant aware application. While in the actual working process, tenant always needs to do personal customization on(More)
—Although segmented voltage-mode R-2R DACs have been widely used for high-precision DACs in static applications, its code-dependent reference current induces a code-dependent IR drop through the reference and ground wires, imposing a limitation on the linearity performance. To alleviate this problem, this paper proposes a simple way to compute the reference(More)
Based on the recently emerging compressive sensing theory, the paper proposes an ultra-low power multichannel data conversion system whose architecture is almost as simple as a single SAR ADC. The proposed architecture is capable of simultaneously converting multi-channel sparse signals while running at the Nyquist rate of only one channel. A chip is(More)
