We consider energy-minimizing divergence-free eigenfields of the curl operator in dimension three from the perspective of contact topology. We give a negative answer to a question of Etnyre and the first author by constructing curl eigenfields which minimize L energy on their co-adjoint orbit, yet are orthogonal to an OVERTWISTED contact structure. We conjecture that K-contact structures on S-b...

background: gossypium arboreum is resistant to cotton leaf curl burewala virus and its cognate cotton leaf curl multan betasatellite (clcubuv and clcumb). however, the g. arboreum wax deficient mutant (gawm3) is susceptible to clcuv. therefore, epicuticular wax was characterized both quantitatively and qualitatively for its role as physical barrier against whitefly mediated viral transmission a...

The purpose of this study was to analyze the results of a training method to increase voluntary recruitment of internal oblique and transversus abdominis muscles. Forty volunteers were assigned to either a Control or an Experimental Group. Training consisted of multisensory (auditory, tactile, visual, and kinesthetic) cuing focused on the lower abdominal muscles during the slow curl-back (eccen...

In the present work, we use reverse non-equilibrium molecular dynamics with adaptive intermolecular reactive empirical bond order interatomic potential to investigate sensitivity of thermal conductivity in (6, 6) single-walled carbon nanotubes (SWCNTs) to side-wall defects and high temperature heat-treatment. Effects of two side-wall defect types and their concentrations are evaluated: chemisor...

The development of secondary flow along a curved channel is fundamental phenomenon occurring in wide range engineering applications, including turbomachinery, aerospace, heating, ventilation, air conditioning, etc. underlying physics about end-wall flows has been well-documented the open literature, while interaction between and side-wall boundary layer, which critical to aerothermal performanc...

We study extensions of piecewise polynomial data prescribed in a patch tetrahedra sharing an edge. show stability the sense that minimizers over spaces with tangential component jumps across faces and curl elements are subordinate broken energy norm to <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" alttext="bold-italic upper H left-parenthes...
