In this paper, we determine the minimum meansquare error (MMSE) performance of a 2–D carrierless AM/PM (CAP) receiver with an ideal (analog feedforward and infinitelength baud-spaced cross-connected) decision feedback equalizer (DFE), in the presence of data-like cross-talks. The MMSE at the slicer is firstly derived for a generic multi-dimensional CAP system with cross-connected DFEs. However,...

The 5'terminal oligopyrimidine (5'TOP) motif is a cis-regulatory RNA element located immediately downstream of the 7-methylguanosine [m7G] cap of TOP mRNAs, which encode ribosomal proteins and translation factors. In eukaryotes, this motif coordinates the synchronous and stoichiometric expression of the protein components of the translation machinery. La-related protein 1 (LARP1) binds TOP mRNA...

Transient expression of proteins in plants has become a choice to facilitate recombinant protein production with its fast and easy application. On the other hand, host defensive mechanisms have been reported to reduce the efficiency of transient expression in plants. Hence, this study was designed to evaluate the effect of cap analog and Potato virus A helper component proteinase (PVA HC-Pro) o...

Capsaicin (CAP), a neurotoxin, has been reported to activate a nonselective cation current in dorsal root ganglion (DRG) neurons. In this paper, we identify and describe the properties of CAP-activated single channels in cultured neonatal rat DRG neurons. We first identified CAP-sensitive whole-cell currents that reversed near 0 mV in physiological solution. In solution containing 140 mM Na+, e...

Influenza virus, which spreads around the world in seasonal epidemics and leads to large numbers of deaths every year, has several ribonucleoproteins in the central core of the viral particle. These viral ribonucleoproteins can specifically bind the conserved 3' and 5' caps of the viral RNAs with responsibility for replication and transcription of the viral RNA in the nucleus of infected cells....

background: accurate impression making is an essential prerequisite for achieving a passive fi t between the implant and the superstructure. the aim of this in vitro study was to compare the three-dimensional accuracy of open-tray and three closed-tray impression techniques. materials and methods: three acrylic resin mandibular master models with four parallel implants were used: biohorizons (b...

We introduce a “smart” cap and trade system that eliminates the welfare costs of asymmetric information (“uncertainty”). This cap increases or decreases in response to technology or macroeconomic shocks. It relies on the market price of certificates to aggregate the relevant information. In the static setting, Weitzman (1974) shows that a tax is more efficient than a (standard) cap if marginal ...

We recently demonstrated that the major decapping activity in mammalian cells involves DcpS, a scavenger pyrophosphatase that hydrolyzes the residual cap structure following 3' to 5' decay of an mRNA. The association of DcpS with 3' to 5' exonuclease exosome components suggests that these two activities are linked and there is a coupled exonucleolytic decay-dependent decapping pathway. We purif...
