Algal bloom is a serious global issue for inland waters, posing pose threat to aquatic ecosystems. The timely and accurate detection of algal blooms critical their control, management forecasting. Optical satellite imagery with short revisit times has been widely used monitor in marine large waters. However, such images typically are coarse resolution, limiting utility map small We developed ne...

Kelly ((1975) Science, 188, 371-372) showed that a centrally-fixated, contrast-reversing edge has a very different effect on the detection of luminance and red-green flicker. Red-green flicker sensitivity was approximately 3-fold greater for a uniform field than for a 'split' field with the two sides flickering out-of-phase. Just the opposite effects were observed for luminance flicker--the spl...

For an edge-bicolored graph G where each edge is colored either red or blue, a vertex set S is a dual feedback vertex set if S hits all blue cycles and red cycles of G. In this paper, we show that a dual feedback vertex set of size at most k can be found in time O∗(ck1) and all minimal dual feedback vertex set of size at most k can be enumerated in time O(c +k 2 ) by compact representations for...

Accurate and effective mapping of forest aboveground biomass (AGB) in heterogeneous mountainous regions is a huge challenge but an urgent demand for resource managements carbon storage monitoring. Conventional studies have related the plot-measured or LiDAR-based to remote sensing data using pixel-based approaches. The object-based relationship between AGB multi-source from LiDAR, multi-frequen...

The role of magnetic nanoparticles (MNPs) in medical applications is rapidly developing. Advances in nanotechnology are bringing us closer to the development of dual and multifunctional nanoparticles that are challenging the traditional distinction between diagnostic and treatment agents. The current use of MNPs in breast cancer falls into four main groups: (1) imaging of primary and metastatic...

Blastomyces dermatitidis, a fungus that can cause fatal infection in humans and other mammals, is not readily recoverable from soil, its environmental reservoir. Because of the red fox's widespread distribution, susceptibility to B. dermatitidis, close association with soil, and well-defined home ranges, this animal has potential utility as a sentinel for this fungus.

Vegetation indices (VIs) derived from optical sensors have been used as proxies for monitoring gross primary productivity (GPP). In contrast to satellite-based VIs, whose temporal resolution is typically limited, especially in cloudy areas, situ VIs may higher resolution. This fine frequency implies much larger sample sizes test the performance of by comparing with eddy covariance-based GPP est...

Two artificial-language learning experiments directly compared English, French, and Dutch listeners' use of suprasegmental cues for continuous-speech segmentation. In both experiments, listeners heard unbroken sequences of consonant-vowel syllables, composed of recurring three- and four-syllable "words." These words were demarcated by (a) no cue other than transitional probabilities induced by ...

In the supplementary material, we provide additional results and discussion of several parts of the main paper. 1. Effects of Non-Idealities In this section, we show simulations for studying the effects of non-idealities of the wedge geometry on edge radiance profiles. These simulations complement the discussion fo Section 4 of the main paper. Figures 1 and 2 show simulations for the effect of ...

Abstract The Arctic is warming twice as fast the rest of planet, leading to rapid changes in species composition and plant functional trait variation. Landscape-level maps vegetation distributions are required expand spatially-limited plot studies, overcome sampling biases associated with most accessible research areas, create baselines from which monitor environmental change. Unmanned aerial v...
