Digital particle image velocimetry measurements of the downwash distribution of a desert locust Schistocerca gregaria [PDF]

open access: yes, 2006
Actuator disc models of insect flight are concerned solely with the rate of momentum transfer to the air that passes through the disc. These simple models assume that an even pressure is applied across the disc, resulting in a uniform downwash ...

Ultrasonic Echosignal Applied to Human Skin Lesions Characterization

open access: yesArchives of Acoustics, 2013
The paper presents a classification of the healthy skin and the skin lesions (basal cell carcinoma) basing on a statistics of the envelope of ultrasonic echoes. The echoes envelopes distributions were modeled using Rayleigh and K-distribution.

On the k-error linear complexity of p(m)-periodic binary sequences

open access: yes, 2019
In this correspondence, we study the statistical stability properties of p(m)-periodic binary sequences in terms of their linear complexity and k-error linear complexity, where 1) is a prime number and 2 is a primitive root modulo p(2).

Cell-specific α and β subunit expression patterns of Na+/K+-ATPases in the common marmoset cochlea

open access: yesScientific Reports
High potassium concentration in the cochlear endolymph electrically drives hair cell activity. Sodium potassium ATPase (Na+/K+-ATPase) is an essential pump for ion homeostasis in the cochlea.

The architecture of the genome integrates scale independence with inverse symmetry

open access: yesAcademia Molecular Biology and Genomics
The simplest building blocks of the genome, the k-mers, show two properties that are widely observed. Their frequency distribution is scale-free (a variant Zipfian distribution), and the inverse symmetry of k-mers is observable on the same ...

Have Gender Gaps in Math Closed? Achievement, Teacher Perceptions, and Learning Behaviors Across Two ECLS-K Cohorts

open access: yesAERA Open, 2016
Studies using data from the Early Childhood Longitudinal Study–Kindergarten Class of 1998–1999 (ECLS-K:1999) revealed gender gaps in mathematics achievement and teacher perceptions.
