The gene myogenin encodes a helix-loop-helix protein whose function is critical to the integrity of the mammalian myogenic cascade. In vitro, the expression of this gene immediately precedes terminal differentiation, as measured by the synthesis of those proteins that make up the contractile apparatus. However, during mammalian development, expression of myogenin and the appearance of sarcomere...

It appears as if the failure of one organ system precipitates the subsequent failure of other organ systems. The aim of the present analysis is to model such system behavior and understand why medical complications accumulate in individual patients. The human body is first modeled as being comprised of multiple subsystems, with the health of each subsystem dependent on input regarding its own h...

Human lens membranes contain the highest cholesterol content of any known biological membrane. Although cholesterol is prone to oxidation, the presence of its oxidation products in human cataract has not been shown before. This study was designed to investigate the presence of cholesterol oxides in human cataractous lenses. Human clear lenses (n = 48) were obtained from Coimbra University Hospi...

In this paper the ensemble of codes formed by a serial concatenation of a repetition code with multiple accumulators connected through random interleavers is considered. Based on finite length weight enumerators for these codes, asymptotic expressions for the minimum distance and an arbitrary number of accumulators larger than one are derived using the uniform interleaver approach. In accordanc...

Green fluorescent protein (GFP) from the jellyfish Aequorea victoria, its GFP variants (Aequorea GFPs), and more recently the novel GFP-like proteins from Anthozoa have greatly advanced our technologies for fluorescently labeling cells, organelles, and proteins. It has been shown, however, that some GFP-like proteins have a tendency to oligomerize and aggregate. Transfection of GFP-like protein...

In this paper, we present a coding theorem for the ensemble of Generalized Repeat Accumulate (GRA m) codes. These codes are the serial concatenation of a terminated convolutional code and m interleaved rate-1 accumulatee codes. This theorem generalizes the results of 1] and 2] by considering outer codes with d f ree = 2 and multiple accumulatee codes. For outer codes with d f ree ≥ 2, it proves...

In this paper, we investigate the optimal design of a wireless-powered covert communication (WP-CC) system, where full-duplex (FD) receiver transmits artificial noise (AN) to simultaneously charge an energy-constrained transmitter and confuse warden’s detection on transmitter’s activity. order achieve higher level covertness, propose probabilistic accumulate-then-transmit (ATT) protocol, is abl...

In [1] [2], product accumulate (PA) codes were proposed and shown to be a class of simple and provably good codes for rate . This work investigates the generalized product accumulate (GPA) codes which have rates over the entire range and which are also “good” both in the maximum likelihood (ML) sense and under the iterative approach. Analysis concentrates on the weight distribution over the cod...

Repeat-Accumulate (RA) codes, consisting of a simple binary repetition followed by a permutation and an accumulator, are converting into quasi-cyclic codes with multiple cross-linked cycles. The algebraic heuristics are used to design codes with an explicit algebraic permutation yielding desirable graph properties. Recursive graph constructions techniques are given for the construction of very ...
