The crucial role played by the myogenic regulatory factors (MRFs) in the development of skeletal muscle has been well characterized. The continued expression of these factors in skeletal muscle of the postnatal animal has led to the suggestion that they may play a role in the regulation of muscle fiber phenotype. The few studies that have examined the expression of MRF-4 in postnatal muscle hav...

The influence of changes in environmental temperature on the mRNA levels of myogenic regulatory factors (MRFs), i.e. MyoD and myogenin, as well as myosin heavy chain (MyHC) were studied during early larval development in rainbow trout and sea bass. Phosphoimager analysis of northern blots indicated that there is an optimum temperature for the RNA transcript levels of MRF and MyHC RNA in trout a...

We present a novel iterative algorithm for detection of binary Markov random fields (MRFs) corrupted by twodimensional (2D) intersymbol interference (ISI) and additive white Gaussian noise (AWGN). We assume a first-order binary MRF as a simple model for correlated images. We assume a 2D digital storage channel, where the MRF is interleaved before being written and then read by a 2D transducer; ...

In this paper we propose a fully connected energy function for Markov Random Field (MRF) modeling which is inspired by Spin-Glass Theory (SGT). Two major tasks in MRF modeling are how to define the neighborhood system for irregular sites and how to choose the energy function for a proper encoding of constraints. The proposed energy function offers two major advantages that makes it possible to ...

Strains of Drosophila melanogaster bearing the male recombination factor 23.5 MRF induce hybrid dysgenesis in a way which is highly reminiscent of the P-M system, and, most probably, causally related to the activity of the transposable element hobo. We have investigated potential interactions between the two systems of hybrid dysgenesis by studying mixed lines derived from bidirectional crosses...

Target Audience This work targets those interested in fast quantitative imaging and abdominal MRI. Purpose Quantitative parameter measurement in the abdomen is extremely challenging due to the anatomy (large organs), field inhomogeneities and extreme physiological motion. Recently, we have introduced a revolutionary paradigm for MRI acquisition, reconstruction, and analysis of MR data, termed M...

Abstract A novel magnetoresistance material based on magnetorheological fluid (MRF) was developed for applications in micro-displacement sensor. The MRF samples were fabricated by dispersing carbonyl iron particles (CIP) into a magnetic ion liquid (MIL) composed of 1-methylethyl ether-3-butylimidazole cation and [Fe 2 Cl 7 ] − anions. characteristics also systematically tested. It found that th...

Magnetorheological fluid (MRF) sandwich beams belong to a class of adaptive that consists MRF sandwiched between two or more face layers and have great prospective for use in semi-active control beam vibrations due their superior vibration suppression capabilities. The composition has strong influence on the properties hence affects characteristics beam. In this work, six samples (MRFs) compose...

During a number of behaviors, including vomiting and some postural adjustments, activity of both the diaphragm and abdominal muscles increases. Previous transneuronal tracing studies using injection of pseudorabies virus (PRV) into either the diaphragm or rectus abdominis (RA) of the ferret demonstrated that motoneurons innervating these muscles receive inputs from neurons in circumscribed regi...

LLE Review, Volume 80 213 Magnetorheological finishing (MRF) is a novel and recently commercialized1 process for figuring and polishing plano, convex, and concave optics—both spherical and aspherical— from a wide variety of optical materials. A recently written review article provides an overview of the history, theory, and implementation of this technology.2 The utility and productivity of MRF...
