Mass transfer in a protein A medium with silica matrix was analyzed this study. Using confocal laser scanning microscopy, we monitored the positional and temporal changes polyclonal human IgG during batch adsorption. simple theoretical model based on Fick’s law of diffusion Langmuir adsorption used to numerically approximate external intraparticle mass-transfer properties single particles. The ...

This study consists of a general review of benign paroxysmal positional vertigo and nystagmus. The main etiopathogenesis, diagnosis, and treatments are evoked. The author describes his experience on the subject.

The critical behavior of frustrated Josephson-junction arrays at f = 1/2 flux quantum per plaquette is considered. Results from Monte Carlo simulations and transfer matrix computations support the identification of the critical behavior of the square and triangular classical arrays and the onedimensional quantum ladder with the universality class of the XY -Ising model. In the quantum ladder, t...

Visual odometry estimates a robot’s ego-motion with cameras installed on itself. With the advantages brought by camera being a sensor, visual odometry has been widely adopted in robotics and navigation fields. Drift (or error accumulation) from relative motion concatenation is an intrinsic problem of visual odometry in long-range navigation, as visual odometry is a sensor based on relative meas...

Deep subspace clustering methods have achieved impressive performance compared with other algorithms. However, most existing suffer from the following problems: 1) they only consider global features but neglect local in self-expressiveness learning; 2) discriminative information of each coefficient matrix; 3) ignore useful long-range dependencies and positional feature representation learning. ...

Dorsoventral polarity of the Drosophila embryo is induced by a ventral extracellular signal, which is produced by a locally activated protease cascade within the extraembryonic perivitelline compartment. Local activation of the protease cascade depends on a positional cue that is laid down during oogenesis outside the oocyte. Here we present evidence that the nudel gene encodes an essential com...

background: meniere’s disease (md) is a chronic illness defined as an idiopathic syndrome of endolymphatic hydrops. benign paroxysmal positional vertigo (bppv) is a balance disorder and can be the sequel of diverse inner ear impairments. objectives: the purpose of this study was to investigate the prevalence of bppv in md patients. materials and methods: all patients with definite or probable m...

We analyze the time complexity of exact real arithmetical algorithms in Möbius number systems. Using the methods of Ergodic theory, we associate to any Möbius number system its transaction quotient T and show that the norm of the state matrix after n transactions is of the order T . We argue that the Bimodular Möbius number system introduced in Kůrka [10] has transaction quotient less than 1.1,...

We present entropy estimates based on molecular dynamics simulations of models of the molten globule state of the protein alpha-lactalbumin at low pH. The entropy calculations use the covariance matrix of atom-positional fluctuations and yield the complete configurational entropy. The configurational entropy of the entire protein and of each of its side chains is calculated. Exposed side chains...
