GAPS IN MAMMALIAN BODY SIZE DISTRIBUTIONS REEXAMINED
Ecology, 1999Holling suggested that discontinuities in the body size distributions among species of animals are a universal feature of terrestrial biomes. We compared the magnitudes of body size gaps of mammal communities of North America and Australia to those generated by a simple random null model.

Gap Size Effect on Tip-Gap Turbulent Flow Structure
41st AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2005This paper presents results from a thorough study of the tip-gap turbulent flow structure in a low-speed linear compressor cascade wind tunnel at Virginia Tech. The endwall pressure measurements and the surface oil flow visualizations were made on a stationary endwall to obtain the flow features and to determine the measurement profiles of interest.

Gap size dependence of the dielectric strength in nano vacuum gaps
IEEE Transactions on Dielectrics and Electrical Insulation, 2013We study the dielectric strength of vacuum gaps of under 100 nm. We find their dielectric strengths to have a power law dependence on the gap size. We apply this power law to find that the dielectric strength of a vacuum gap of 10 nm between two tungsten electrodes is 6.5 V/nm.

Advanced Materials Research, 2012
Reports on the alloys formed from immiscible atoms when they are contained in a nano-sized system have initiated several research activities in the recent years. Bridging of the miscibility gap at nanoscale is significant as it has the potential to produce novel alloy materials with useful technological applications.

Estimation of Canopy Gap Size and Gap Shape Using a Hemispherical Photograph
Trees - Structure and Function, 2009Gap size and gap shape are two important properties of forest gaps that can influence microsite conditions in a forest stand and determine the recruitment and establishment of trees. There is no universally adopted method for measuring the gap size, although several options are available.

The Relationship Between the Characteristics of Speech and Velopharyngeal Gap Size
The Cleft Palate-Craniofacial Journal, 2003Objective The purpose of this study was to examine the relationship between perceptual characteristics of hypernasality, nasal emission and nasal rustle, and size of the velopharyngeal gap. Design A retrospective medical chart review.

Forest Spatial Dynamics with Gap Expansion: Total Gap Area and Gap Size Distribution
Journal of Theoretical Biology, 1996Abstract Recent studies on forest dynamics in diverse forested ecosystems suggest that forest stands are disturbed more frequently if they are next to existing gaps, and that gaps once formed tend to expand their area in subsequent years. We examine total gap area and the size distribution of gaps at equilibrium in a lattice-structured forest model ...

On the Sizes of Gaps in the Fourier Expansion of Modular Forms
Canadian Journal of Mathematics, 2005AbstractLet be a cusp form with integer weight k ≥ 2 that is not a linear combination of forms with complex multiplication. For n ≥ 1, letConcerning bounded values of i f (n) we prove that for ∊ > 0 there exists M = M(∊, f ) such that Using results of Wu, we show that if f is a weight 2 cusp form for an elliptic curve without complex multiplication,

Size Effect of Heat Transport in Microscale Gas Gap
IEEE Transactions on Industrial Electronics, 2017Microscale gas gaps commonly exist in gas thermal conductance related microdevices, such as micro-hot-plate gas sensors and micro-Pirani vacuum gauges. In these devices, thermal conduction of the gas gaps is an important issue for their performance. Although simulations for size effect of the thermal conduction in microscale gas gaps have been carried ...

Closing the Gap for Coded Caching with Distinct File Sizes
2019 IEEE International Symposium on Information Theory (ISIT), 2019Coded caching can exploit multicast opportunities even when multiple users request different pieces of content, and thus can significantly reduce the backhaul requirement to serve high-volume content. A common assumption in existing studies of coded caching is that all files are with the same size, which however may not be true in reality. Our previous
