Sm and Sm-like proteins are key components of small ribonucleoproteins involved in many RNA and DNA processing pathways. In eukaryotes, these complexes contain seven unique Sm or Sm-like (Lsm) proteins assembled as hetero-heptameric rings, whereas in Archaea and bacteria six or seven-membered rings are made from only a single polypeptide chain. Here we show that single Sm and Lsm proteins from ...

The present work was undertaken in order to investigate the effects of static magnetic field (SMF) on growth rates, hematopoiesis, plasmatic proteins levels, glucose concentration, lactate dehydrogenase (LDH) and transaminases activities in male rats. Sub-acute exposure of rats during 5 consecutive days to SMF (1h/day at 128mT) induced an increase of plasma LDH activity (+38%, p<0.05), and gluc...

We propose a unified framework to speed up the existing stochastic matrix factorization (SMF) algorithms via variance reduction. Our framework is general and it subsumes several well-known SMF formulations in the literature. We perform a non-asymptotic convergence analysis of our framework and derive computational and sample complexities for our algorithm to converge to an -stationary point in ...

High frequency acoustic waves confined inside a suspended core fiber (SCF) are revealed by numerical simulations for the first time. A standard single mode optical (SMF) is modelled to explain current research limitations. The response and energy concentrated in both fibers evaluated from 50 56 MHz with 3D finite element method. simulated dispersion curves compared Pochhammer–Chree solutions. S...

BACKGROUND MRI has developed into one of the most important medical diagnostic imaging modalities, but it exposes staff to static magnetic fields (SMF) when present in the vicinity of the MR system, and to radiofrequency and switched gradient electromagnetic fields if they are present during image acquisition. We measured exposure to SMF and motion-induced time-varying magnetic fields (TVMF) in...

This study introduced a novel magnetic-field regulation method in metallic additive manufacturing to achieve the refined grain structure and enhanced mechanical properties without post-treatment composition changes. As showcase material, Ti6Al4V alloy was fabricated using direct energy deposition under static magnetic field (SMF). It is found that transverse SMF of 0.55 T can effectively regula...

Under a single-pulse magnetic field (SMF), we proposed thermoacoustic (TA) concentration imaging method of nanoparticles (MNPs). This derived the relationship between MNPs and TA signals based on mechanism effect. In simulation, ideally reconstructed map from simulated signals. It proves feasibility method. experiment, multi-channel acquisition system was built, MNP suspension with iron 1 mg/ml...

This paper shows that optimal set-membership filtering (SMF) is identical to minimax ( ) filtering, if optimal SMF corresponds to the smallest error bound specification that leads to a non-empty feasible solution. An adaptive minimax filtering algorithm that uses optimal quadratic approximations to the minimax cost function is proposed for adaptive implementation of optimal SMF. The proposed al...
