The Response of Test Masses to Gravitational Waves in the Coordinates of a Local Observer [PDF]

open access: yes, 2004
The response of laser interferometers to gravitational waves has been calculated in a number of different ways, particularly in the transverse-traceless and the local Lorentz gauges.

Personalization of Saliency Estimation [PDF]

open access: yes, 2012
Most existing saliency models use low-level features or task descriptions when generating attention predictions. However, the link between observer characteristics and gaze patterns is rarely investigated. We present a novel saliency prediction technique

A comparative analysis of manual glenoid version measurement using two- and three-dimensional computed tomography imaging techniques [PDF]

open access: yesClinics in Shoulder and Elbow
Background Accurate measurement of glenoid version is essential for optimal implant positioning in shoulder arthroplasty. This study compared the accuracy and reliability of unformatted two-dimensional computed tomography (2D-CT), formatted 2D-CT, and ...

Air-Gap Flux Oriented Vector Control Based on Reduced-Order Flux Observer for EESM

open access: yesEnergies, 2021
Electrically excited synchronous motor (EESM) has the characteristics of high order, nonlinear and strong coupling, so it is difficult to be controlled. However, it has the advantages of adjustable power factor, high efficiency, and high precision torque

Observed Subdecadal Variations of European Summer Temperatures [PDF]

open access: yesGeophysical Research Letters, 2020
AbstractWe identify subdecadal variations in European summer temperatures in coupled and uncoupled century‐long reanalyses. Spectral analyses reveal significant peaks at 5–10 years in the midtwentieth century. The subdecadal variations show substantial amplitudes of ~1–1.5 °C, associated with extremely warm summers during their positive phases.

Can an observer really catch up with light [PDF]

open access: yes, 2002
Given a null geodesic $\gamma_0(\lambda)$ with a point $r$ in $(p,q)$ conjugate to $p$ along $\gamma_0(\lambda)$, there will be a variation of $\gamma_0(\lambda)$ which will give a time-like curve from $p$ to $q$.

Multicenter evaluation of the PASS score as a negative predictive tool and the impact of inter-observer variability in pheochromocytoma and paraganglioma risk stratification [PDF]

open access: yesJournal of Pathology and Translational Medicine
Background The Pheochromocytoma of the Adrenal Gland Scaled Score (PASS) is widely used for risk stratification in pheochromocytoma and paraganglioma (PPGL), but its clinical utility is limited by inter-observer variability of its parameters and ...
