Is there a common factor for vision?

Michael Herzog, Christine Mohr, Aaron Michael Clarke

In cognition, common factors play a crucial role. For example, different types of intelligence are highly correlated, pointing to a common factor, which is often called g. One might expect that a similar common factor would also exist for vision. Surprisin ...

Gait Analysis Using Shoe-worn Inertial Sensors: How is foot clearance related to walking speed?

Kamiar Aminian, Farzin Dadashi, Benoît Mariani

Spatiotemporal gait analysis with body worn inertial sensors improves diagnosis in clinical practice. Most of the gait performance measures are affected by walking speed. However, it has not been investigated that how much information foot clearance parame ...

Pre-Impact Fall Detection: Optimal Sensor Positioning Based on a Machine Learning Paradigm

Silvestro Micera, Fiorenzo Artoni

The aim of this study was to identify the best subset of body segments that provides for a rapid and reliable detection of the transition from steady walking to a slipping event. Fifteen healthy young subjects managed unexpected perturbations during walkin ...

Gait disturbances as specific predictive markers of the first fall onset in elderly people: a two-year prospective observational study

Jean-Baptiste Mignardot

Falls are common in the elderly, and potentially result in injury and disability. Thus, preventing falls as soon as possible in older adults is a public health priority, yet there is no specific marker that is predictive of the first fall onset. We hypothe ...

Recovering Neugebauer colorant reflectances and Ink-spreading curves from printed color images

Roger Hersch, Thomas Bugnon

Spectral reflection prediction models, although effective, are impractical for certain industrial applications such as self-calibrating devices and online monitoring because their calibration requires specific color-constant calibration patches. Using the ...

Planck 2013 results. XII. Diffuse component separation

Xin Chen, Julien Lesgourgues, Fabio Finelli

Planck has produced detailed all-sky observations over nine frequency bands between 30 and 857 GHz. These observations allow robust reconstruction of the primordial cosmic microwave background (CMB) temperature fluctuations over nearly the full sky, as wel ...

A low-cost sensible heat flux sensor for potential use in wireless sensor networks and citizen observatories

Wolf Hendrik Huwald, Alexander Bahr, Steven Vincent Weijs, Chad Higgins, Tristan Jonas Brauchli, Nicolas Bigler

The sensible heat flux is an important component of the land-atmosphere energy exchange but is relatively expensive to measure using standard techniques such as eddy covariance. Application of a flux variance method based on Monin-Obukhov similarity theory ...

Pattern-based sensing of aminoglycosides with fluorescent amphiphiles

Rosario Scopelliti, Kay Severin

A mixture of two amphiphiles with fluorescent head groups can be used as a sensing ensemble for the pattern-based analysis of aminoglycoside antibiotics. In buffered aqueous solution, the amphiphiles form a dynamic mixture of micellar aggregates. In the pr ...

Planck 2013 results. XXIII. Isotropy and statistics of the CMB

Julien Lesgourgues, Jason Douglas McEwen, Ji Hyun Kim, Fabio Finelli

The two fundamental assumptions of the standard cosmological model - that the initial fluctuations are statistically isotropic and Gaussian - are rigorously tested using maps of the cosmic microwave background (CMB) anisotropy from the Planck satellite. Th ...

Principal Flows

Victor Panaretos, Tung Huy Pham, Zhigang Yao

We revisit the problem of extending the notion of principal component analysis (PCA) to multivariate datasets that satisfy nonlinear constraints, therefore lying on Riemannian manifolds. Our aim is to determine curves on the manifold that retain their cano ...
