Probability density estimation from optimally condensed data samples [PDF]

open access: yes, 2003
The requirement to reduce the computational cost of evaluating a point probability density estimate when employing a Parzen window estimator is a well-known problem.

Clinical factors associated with trabecular bone score.

open access: yes, 2013
Dual-energy X-ray absorptiometry (DXA) measurement of bone mineral density (BMD) is the reference standard for diagnosing osteoporosis but does not directly reflect deterioration in bone microarchitecture.

Global imaging of the Earth's deep interior: seismic constraints on (an)isotropy, density and attenuation

open access: yes, 2013
Seismic tomography is the principal tool to probe the deep interior of the Earth. Models of seismic anisotropy induced by crystal alignment provide insight into the underlying convective motion, and variations of density allow us to discriminate between ...

Mammographic density. Measurement of mammographic density [PDF]

open access: yesBreast Cancer Research, 2008
Mammographic density has been strongly associated with increased risk of breast cancer. Furthermore, density is inversely correlated with the accuracy of mammography and, therefore, a measurement of density conveys information about the difficulty of detecting cancer in a mammogram.

The imprint of crustal density heterogeneities on regional seismic wave propagation

open access: yes, 2016
Density heterogeneities are the source of mass transport in the Earth. However, the 3-D density structure remains poorly constrained because travel times of seismic waves are only weakly sensitive to density.

Bone Mineral Density of Adolescent Female Tennis Players and Nontennis Players

open access: yesJournal of Osteoporosis, 2012
The purpose of this study was to determine differences in bone mineral density (BMD) among adolescent female tennis players (TPs) and nontennis players (NTPs) and to assess body composition as a predictor variable of BMD.

Effects of anti-resorptive agents on trabecular bone score (TBS) in older women.

open access: yes, 2013
We evaluated the longitudinal effects of anti-resorptive agents (534 treated women vs. 1,150 untreated) on lumbar spine bone mineral density (BMD) and trabecular bone score (TBS). TBS was responsive to treatment in women over age 50.

Examination of pyroelectric power generation over a wide temperature range by controlling the Zr:Sn composition ratio of PLZST

open access: yesJournal of Asian Ceramic Societies, 2021
Several studies have been conducted on energy harvesting, which involves conversion of unused environmental energy into a power source. More than half of the energy consumed is wasted as heat.

Italian Multicenter Study on Low-Density Lipoprotein Apheresis Working Group 2009 Survey

open access: yes, 2013
We present results of the second survey of the Italian Multicenter Study on Low-Density Lipoprotein Apheresis (IMSLDLa-WG/2). The study involved 18 centers in 2009, treating 66 males and 35 females, mean age 47 +/- 18 years.

DENSITY OF STATES METHOD AT FINITE ISOSPIN DENSITY [PDF]

open access: yesModern Physics Letters A, 2004
The density of states method is applied for lattice QCD at a finite isospin density. The advantage of this method is that one can easily obtain results for various values of parameters (quark mass, coupling constant and the number of flavors). We compare results for the chiral condensate and the quark number density with those from the R-algorithm and
