In frequency division duplex mode, the downlink channel state information (CSI) should be sent to the base station through feedback links so that the potential gains of a massive multiple-input multiple-output can be exhibited. However, such a transmission is hindered by excessive feedback overhead. In this letter, we use deep learning technology to develop CsiNet, a novel CSI sensing and recov...

A charge-successive integrator (CSI) VLSI with a wide dynamic range has been developed for the front-end electronics of the Telescope Array project. The CSI has more than a 14-bit dynamic range and successively integrates the charge from a photomultiplier tube every 200 ns. We have newly designed an offset-compensated charge integrator to reduce the offset voltage and the 1 noise. We expect tha...

Both linear and nonlinear transmit precoding strategies based on accurate channel state information (CSI) can significantly increase available throughput in a multiuser wireless system. With propagation delay, infrequent channel updates, lag due to network layer overhead, and time-varying node position or environment characteristics, channel knowledge becomes outdated and CSI-based transmission...

Context-specific independence (CSI) refers to conditional independencies that are true only in specific contexts. It has been found useful in various inference algorithms for Bayesian networks. This paper studies the role of CSI in general. We provide a characterization of the computational leverages offered by CSI without referring to particular inference algorithms. We identify the issues tha...

The Chemical Shift Index or CSI 3.0 (http://csi3.wishartlab.com) is a web server designed to accurately identify the location of secondary and super-secondary structures in protein chains using only nuclear magnetic resonance (NMR) backbone chemical shifts and their corresponding protein sequence data. Unlike earlier versions of CSI, which only identified three types of secondary structure (hel...

INTRODUCTION The relationship between cervical spine injury (CSI) and helmet in head injury (HI) patients following motorcycle crashes is crucial. Controversy still exists; therefore we evaluated the effect of various types of helmets on CSI in HI patients following motorcycle crashes and researched the mechanism of this effect. PATIENTS AND METHODS A total of 5225 patients of motorcycle cras...

Multi-user multiple-input multiple-output (MU-MIMO) systems provide a significantly increased capacity and spectral efficiency by exploiting the benefits of space division multiple access (SDMA). The channel state information (CSI) at the base station (BS) is used to precode the transmit signals and to simplify the processing at the users’ terminals. If perfect CSI is available at the transmitt...

PURPOSE To investigate the expression of CDC25B, which is a member of the cyclin-dependent kinase activating phosphatase family, in diffuse astrocytoma (DA), anaplastic astrocytoma (AA), glioblastoma multiforme (GBM), pilocytic astrocytoma (PA) and reactive gliosis (RG). Also, to study the relationship of the expression level of CDC25B with clinical parameters and with p53 and Ki-67 proliferati...

INTRODUCTION Orthotopic liver transplantation (OLT) is accompanied by a significant postoperative infection risk. Immunosuppression to prevent rejection increases the susceptibility to infections, mainly by impairing the adaptive immune system. Genetic polymorphisms in the lectin complement pathway of the donor have recently been identified as important risk determinants of clinically significa...
