Mutations in simple sequence repeat tracts are a major mechanism of phase variation in several bacterial species including Campylobacter jejuni. Changes in repeat number of tracts located within the reading frame can produce a high frequency of reversible switches in gene expression between ON and OFF states. The genome of C. jejuni strain NCTC11168 contains 29 loci with polyG/polyC tracts of s...

UNLABELLED Mutations in RPGRIP1 are associated with early onset retinal degenerations in humans and dogs. Dogs homozygous for a 44 bp insertion including a polyA(29) tract potentially leading to premature truncation of the protein, show cone rod degeneration. This is rapid and blinding in a colony of dogs in which the mutation was characterised but in dogs with the same mutation in the pet popu...

The theory of electrokinetic ion transport in cylindrical channels a fixed surface charge density is revisited. Attention focused on the impact hydrophobic slippage and mobility adsorbed charges. We formulate generalized Onsager relations for cylinder an arbitrary radius then derive exact expressions mean electro-osmotic conductivity. To employ these expressions, we perform additional electrost...

a modified model has been analytically developed to describe the induction time of an elliptic air bubble in contact with an elliptic hydrophobic oil droplet. the role of hydrophobicity was revealed in the slippage of liquid over the surfaces of bubble and droplet. in this condition, the analytical relationships for pressure distribution and consequently hydrodynamic resistance force through th...

Advances in sequencing technologies have enabled direct quantification of genome-wide errors that occur during RNA transcription. These errors occur at rates that are orders of magnitude higher than rates during DNA replication, but due to technical difficulties such measurements have been limited to single-base substitutions and have not yet quantified the scope of transcription insertions and...

Abstract This paper focuses on the localization of a McNamee wheel mobile robot, which has six states motion and more complex kinematic equations than normal robot using wheel. In this paper, model is developed, extended Kalman filter algorithm (EKF) used to fuse inertial measurement unit (IMU) encoder odometer information estimate position state eliminate environmental noise effect slippage.

In the title compound, C(16)H(12)BrFO(3)S, the 4-fluoro-phenyl ring makes a dihedral angle of 72.35 (5)° with the mean plane [r.m.s. deviation = 0.008 (1) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked into [010] chains via two different inversion-generated pairs of C-H⋯O hydrogen bonds. The crystal structure also exhibits slipped π-π inter-actions between the benzene ring...

In the title compound, C(14)H(9)NO(2), the phenyl ring makes a dihedral angle of 50.59 (5)° with the mean plane of the isatin fragment. In the crystal, mol-ecules are linked through weak inter-molecular C-H⋯O hydrogen bonds. The crystal structure also exhibits two slipped π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.968 (3) Å, inter-plan...

A computer-controlled vehicle that is part of a mobile nursing robot system is described. The vehicle applies a motion control strategy that attempts to avoid slippage and minimize position errors. A cross-coupling control algorithm that guarantees a zero steady-state orientation error (assuming no slippage) is proposed and a stability analysis of the control system is presented. Results of exp...
