Escherichia coli is a motile bacterium that moves up a chemoattractant gradient by performing a biased random walk composed of alternating runs and tumbles. This paper presents calculations of the chemotactic drift velocity vd (the mean velocity up the chemoattractant gradient) of an E. coli cell performing chemotaxis in a uniform, steady shear flow, with a weak chemoattractant gradient at righ...

Rotation modulation is an effective method to enhance the accuracy of an inertial navigation system (INS) by modulating the gyroscope drifts and accelerometer bias errors into periodically varying components. The typical RINS drives the inertial measurement unit (IMU) rotation along the vertical axis and the horizontal sensors' errors are modulated, however, the azimuth angle error is closely r...

A number of aspects of ionospheric chemistry are revisited. The review discusses in detail only work performed at AFRL, but other work is mentioned. A large portion of the paper discusses measurements of the kinetics of upper ionospheric reactions at very high temperatures, i.e. the upper temperature range has been extended to at least 1400 K and in some cases to 1800 K. These temperatures are ...

Triangular fully packed loop configurations (TFPLs) came up in the study of fully packed loop configurations on a square (FPLs) corresponding to link patterns with a large number of nested arches. To a TFPL is assigned a triple (u, v;w) of 01-words encoding its boundary conditions that must necessarily satisfy d(u) + d(v) 6 d(w), where d(u) denotes the number of inversions in u. Wieland gyratio...

Despite several findings of perceptual asynchronies between object features, it remains unclear whether independent neuronal populations necessarily code these perceptually unbound properties. To examine this, we investigated the binding between an object's spatial frequency and its rotational motion using contingent motion aftereffects (MAE). Subjects adapted to an oscillating grating whose di...

Studbook information collected from 1988 to 2011 in Jafarabad breeding station of Moghani sheep, north-west of Iran, related to 9,457 lambs were used to study the genetic diversity and to evaluate the effectiveness of an implemented rotational mating scheme using pedigree analysis. Lambs born during 2009-2011 were considered as reference population. Means inbreeding and average coancestry for t...

A hybrid-kinetic model (Vlasov ions and cold-fluid electrons) is used to develop a fully nonlocal theory of the mirror-drift-cone instability. The stability analysis assumes electrostatic flute perturbations about a 0 cylindrical ion equilibrium f (HwiPe, v ), where w = const.=angular velocity of mean rotation. The radial eigenvalue equation for the potential amplitude $(r) is solved 0 exactly ...

The rotational spectra of C(3)N(-), C(4)H(-), and C(4)D(-) have been measured at high-spectral resolution by Fourier transform microwave spectroscopy. For both C(3)N(-) and C(4)D(-), hyperfine structure in the lowest-J transitions has been resolved and measured to better than 0.1 ppm. The quadrupole coupling constants eQq for both anions are close to those of the neutral counterparts C(3)N and ...

This paper introduces SDF-TAR: a real-time SLAM system based on volumetric registration in RGB-D data. While the camera is tracked online on the GPU, the most recently estimated poses are jointly refined on the CPU. We perform registration by aligning the data in limited-extent volumes anchored at salient 3D locations. This strategy permits efficient tracking on the GPU. Furthermore, the small ...

Sompolinski and Zippelius (1981) propose the study of dynamical systems whose invariant measures are the Gibbs measures for (hard to analyze) statistical physics models of interest. In the course of doing so, physicists often report of an \aging" phenomenon. For example, aging is expected to happen for the Sherrington-Kirkpatrick model, a disordered mean-eld model with a very complex phase tran...
