Abstract Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge miniaturized, ultracompact and kaleidoscopic optical vortex generators. However, it is often required to segment or interleave independent sub-array metasurfaces multiplex vortices in a single nano-device, which turn affects the device’s compactness channel capacity. Here,...

This paper presents an investigation on the influence of various factors rolling shear (RS) properties timber feedstock for cross laminated (CLT) available from Australian plantation forest resources. Comparison RS between three softwood species namely southern pine, radiata pine and hoop are presented. Furthermore, effect modulus elasticity (MOE), equilibrium moisture content (EMC), aspect rat...

Drought and mountain pine beetle (Dendroctonus ponderosae Hopkins) outbreaks have affected millions of hectares of high-elevation conifer forests in the Northern Rocky Mountains during the past century. Little research has examined the distinction between mountain pine beetle outbreaks and climatic influence on radial growth in endangered whitebark pine (Pinus albicaulis Engelm.) ecosystems. We...

in this paper, we investigate the continuity of linear and sublinear correspondences defined on cones in normed spaces. we also generalize some known results for sublinear correspondences.

Previous evidence has shown that the number of L and M cones in retina varies significantly between subjects. However, it is not clear how the variation of L/M ratio changes the behavioral performance of the subject. A model of transformation of data from retina to visual cortex for evaluation of various L/M cones ratios is presented. While L/M cone ratios close to 1 brings the best performance...

frothers havea profoundeffectonbubble size and also flotation efficiency. in present study the effect of type and dosage of frothers on the flotation response of coarse particles of quartz was investigated.  therefore, flotation response of coarse particles using frothers such as mibc, pine oil, poly propylene glycol with concentration of 0, 25, 50 and 75 g/t, was obtained respectively. for all...

Concurrent with fire exclusion, shortleaf pine loblolly pine hybrids have increased throughout the southeastern USA and may threaten the genetic integrity of shortleaf pine. Historically, fire favored shortleaf pine over other southern pine species, especially loblolly pine, with which it shares a broad sympatric natural range. Shortleaf pine seedlings have a morphological adaptation (basal cro...

cardiovascular disease (cvd) is the driving force behind the discrepancy in life expectancy between indigenous and nonindigenous groups in many countries. preceding cvd many indigenous groups exhibit a cluster of cardiometabolic risk factors, including overweight-obesity, diabetes, high cholesterol, and high blood pressure. in turn, modifiable lifestyle risk factors contribute to the developmen...

Seed supply is one of the most important determinants of successful natural regeneration. We conducted a study to determine the potential contribution of cones in the tops of harvested loblolly pines (Pinus tueda L.) to the stand’s seed supply if trees were felled after seed maturation but before dispersal, Closed cones, collected in October 1996, were stored in wire cages with periodic removal...
