A bstract We study the impact of sphaleron-induced thermal friction on axion dark-matter abundance due to interaction an axion-like particle (ALP) with a dark non-abelian gauge sector in secluded bath. Thermal can either enhance relic density by delaying onset oscillations or suppress it damping them. derive analytical formula for frictional adiabatic invariant , which remains constant along ev...

A bstract We explore the cosmology and phenomenology of millicharged millicharge-like dark matter with masses from 1 eV to 10 keV charges − 18 14 . Dark in this mass range cannot be thermally produced, but can arise non-thermal mechanisms. propose a concrete model employing spontaneously broken approximate global symmetry, which is produced via misalignment mechanism. show that production mecha...

Fiber reinforced polymer (FRP) laminates are being used as external reinforcement for strengthening concrete members. The performance of unidirectional FRP laminates is highly dependent on fiber orientation with respect to applied load direction. In the case of fabrication by manual lay-up, it is possible to have fiber plies installed with improper orientation. In this project, the degradation ...

We address two quality issues in endoscopy videos originating from: (a) Colour Channel Misalignment: In current endoscope systems, the colour channel images are most commonly acquired sequentially at different time instances. Whenever the camera moves significantly between acquisition instances, the colour channels get misaligned. This misalignment degrades the quality of the video due to the a...

Misalignment of interaural cortical response maps in asymmetric hearing loss evolves from initial gross divergence to near convergence over a 6 month recovery period. The evolution of left primary auditory cortex (AI) interaural frequency map changes is chronicled in squirrel monkeys with asymmetric hearing loss induced by overstimulating the right ear with a 1 kHz tone at 136 dB for 3 h. AI fr...

Manufacturing flaws and construction realities always impose a misalignment between multiple sensors (even though they remain rigidly coupled together). An algorithm was developed to determine the misalignment between any two three-axis sensors whose unit vectors are known in the inertial frame and can be measured in body coordinates. The input to the misalignment algorithm is a locus of measur...

Axially symmetric telescopes produce well known “Seidel” off-axis third-order aberration patterns: coma, astigmatism, curvature of field and distortion. When axial symmetry is broken by the small misalignments of optical elements, additional third-order aberration patterns arise: one each for coma, astigmatism and curvature of field and two for distortion. Each of these misalignment patterns is...

Internal mapping of the external environment is carried out using the receptive fields of topographic neurons in the brain, and in a normal barn owl the aural and visual subcortical maps are aligned from early experiences. However, instantaneous misalignment of the aural and visual stimuli has been observed to result in adaptive behavior, manifested by functional and anatomical changes of the a...

The value of information technology (IT) investment comes increasingly from its ability to complement and enable business strategies and organizational capabilities. As a general purpose technology, however, IT could either a complement or a constraint. Making the right IT investment, particularly the right IT infrastructure investment could thus have far-reaching impact on a firm " s IT invest...
