Abstract:

Abstract While the importance of selecting a neighborhood size for competition studies has been documented, the choice of plot sizes has received little attention when measuring the influence of overstory trees on growing conditions of understory seedlings. Based on data from four sites, we show how plot sizes for measures of overstory cover (using a “cone” approach) and basal area (using an angle gauge) were related. The relationship was a function of the height/diameter ratio of the overstory trees, with taller trees increasing the plot sizes for “cone” plots and trees with larger diameters

Abstract:

Microscopists and scientific photographers sometimes find it desirable or necessary to record a larger field size than the lowest power objective can cover using brightfield illumination. This applies to the largest thin sections examined by biologists and geologists in transmitted light and the opaque, planar specimens examined by the materials scientist in reflected light. These needs were once well met by Leitz with their Panphot and Aristophot systems and to a lesser extent by Zeiss with their Ultraphot II.

The scale sizes of intense (>0.15 V/m, mapped to the ionosphere), high-altitude (4–7 RE geocentric distance) auroral electric fields (measured by the Cluster EFW instrument) have been determined in a statistical study.

The electric field scale sizes are further compared with the scale sizes and widths of the associated field-aligned currents (FACs). The influence of, or relation between, other p

Abstract:

Segmentation of objects with various sizes is relatively less explored in medical imaging, and has been very challenging in computer vision tasks in general. We hypothesize that the receptive field of a deep model corresponds closely to the size of object to be segmented, which could critically influence the segmentation accuracy of objects with varied sizes. In this study, we employed “AmygNet”, a dual-branch fully convolutional neural network (FCNN) with two different sizes of receptive fields, to investigate the effects of receptive field on segmenting four major subnuclei of bi

Soybean cyst nematode (SCN; Heterodera glycines Ichinohe) is a major pathogen of soybean [Glycine max (L.) Merr.] in the United States. The spatial distribution of SCN in 10 naturally infested research sites in North Dakota was examined between 2006 and 2009. Egg densities were measured in plots and expressed as arithmetic means or grouped into classes using two categorical scales based on the effect of SCN on yield. Data were used to determine spatial distribution, egg cluster sizes, minimum plot sizes, and replications in field experiments. SCN populations varied among plots from undetected

Some of these patients have a retinal-specific mutation in the protein nyctalopin, which is also present in the Nyxnob mouse. In these mice, retinal ganglion cells (RGCs) have oscillatory activity, which leads to expanded axonal projections towards the dLGN and consequently to a desegregation of retinal projections to the brain. In this study, we investigate whether the receptive fields of Nyxnob RGCs have also expanded by measuring the size of their receptive fields using MEA recordings. Contrar

Using a novel functional MRI model–based method we identified two maps—TO-1 and TO-2—and measured population receptive field (pRF) sizes within these maps.

Abstract:

Within the field of performance of agricultural experimentation we have some obstacles related to conducting experiments, the biggest of which is the comparison between treatments with the greatest possible precision, in order to arrive at safe conclusions from the observed results. The objective of this work was to evaluate the relationship between the plot sizes and the stand determination, height at maturation, as well as soybean yield. Three areas were cultivated with soybean for this purpose. In the plant stand determination 18 plot sizes were tested, at the plant height at maturation 14

Abstract:

Perhaps unexpectedly, there is a rich and deep connection between field of values of characters, their degrees and the structure of a finite group. Some of the fundamental results on the degrees of characters of finite groups, as the Ito–Michler and Thompson's theorems, admit a version involving only characters with certain fixed field of values ([DNT, NS, NST2, NT1, NT3]).

Abstract:

Separated E/ H-field heating in microwave cavities enables us to examine the microwave loss mechanisms. We prepared mixtures of SiO2 particles (having almost no microwave loss) and Ag particles with micrometer- and nano-sizes. Their average impedance and dielectric constants were measured. Electric conductivity exhibited percolation behavior at a specific threshold of Ag fraction. When the mixtures were heated in the separated fields, H-field heating was dominant in all the fraction ranges for the micrometer-sized Ag mixture. However, E-field heating was dominant below the percolation threshol

Abstract:

Abstract In this work, we propose mathematical formulations that detail the effect of the dielectric strength of dielectric material on the spatial distribution of electric field in an infinite space with a conducting plate. Using the dielectric strength of air as the maximum limit for the magnitude of electric field intensity and the equivalence of stored charge between two different zones, we determine the size of the dielectric breakdown region (the extended region with ionized material) for the conducting strip and the conducting disk charged to an electric voltage. The size of dielectric

Abstract:

Abstract Progeny from a sexual outcross between opposite mating types of Pythium sylvaticum were analyzed for inheritance of RFLP and random amplified polymorphic DNA (RAPD) markers. Although most were inherited in expected Mendelian frequencies, several were not. Pulsed field gel electrophoresis was employed to examine these unexpected patterns of marker inheritance at a karyotypic level. Parental oogonial and antheridial isolates had different electrophoretic karyotypes and minimum number of chromosome-sized DNAs (13 and 12, respectively), however, summation of the sizes of all chromosomal b

Abstract:

Riprap rock and large-sized aggregates have been used extensively in geotechnical and hydraulic engineering. They essentially provide erosion control, sediment control, and scour protection. The sustainable and reliable use of riprap materials demands efficient and accurate evaluation of their large particle sizes, shapes, and gradation information at both quarry production lines and construction sites. Traditional methods for assessing riprap geometric properties involve subjective visual inspection and time-consuming hand measurements. As such, achieving the comprehensive in-situ characteriz

Abstract:

The critical frontier of the isotropic antiferromagnetic Heisenberg model in a magnetic field along the z-axis has been studied by mean-field and effective-field renormalization group calculations. These methods, abbreviated as MFRG and EFRG, are based on the comparison of two clusters of different sizes, each of them trying to mimic a specific Bravais lattice. The frontier line in the plane of temperature versus magnetic field was obtained for the simple cubic and the body-centered cubic lattices. Spin clusters with sizes N = 1, 2, 4 were used so as to implement MFRG-12, EFRG-12 and EFRG-24 n

The objective of this study was to estimate the optimum plots size for experiments with annatto. The uniformity assay consisted of 12 rows with 12 plants in each row. The variety Bico de Pato was used, planted in 5 x 4 m spacing and evaluated at 5 years of age. Three methods were used: maximum curvature, modified maximum curvature and the comparison of variances. The plot size estimate varied according to the methodology used and the characteristic analyzed. The adequate plot size was found to be 107.2 m² (5 plants) using the modified maximum curvature method, which resulted in more precise es

Abstract:

The noninvasive estimation of neuronal receptive field (RF) properties in vivo allows a detailed understanding of brain organization as well as its plasticity by longitudinal following of potential changes. Visual RFs measured invasively by electrophysiology in animal models have traditionally provided a great extent of our current knowledge about the visual brain and its disorders. Voxel-based estimates of population RF (pRF) by functional magnetic resonance imaging (fMRI) in humans revolutionized the field and have been used extensively in numerous studies. However, current methods cannot es
