Arm velocity distribution during daily activity: objective outcome evaluation after shoulder surgery

Kamiar Aminian, Alain Farron, Cyntia Duc

This study proposed a new metric to assess the arm mobility based on the monitoring of daily activity using inertial sensors. Forty-one healthy participants and 21 patients suffering from rotator cuff tear disease were evaluated using a clinical questionna ...

FORWARD BROWNIAN MOTION

We consider processes which have the distribution of standard Brownian motion (in the forward direction of time) starting from random points on the trajectory which accumulate at -∞ 1. We show that these processes do not have to have the distribution of st ...

Marginal Stability Constrains Force and Pair Distributions at Random Close Packing

Matthieu Wyart

The requirement that packings of frictionless hard spheres, arguably the simplest structural glass, cannot be compressed by rearranging their network of contacts is shown to yield a new constraint on their microscopic structure. This constraint takes the f ...

Conformational distribution of bradykinin [bk+2H]2+ revealed by cold ion spectroscopy coupled with FAIMS

Thomas Rizzo, Annette Svendsen, Georgios Papadopoulos

We employ Cold Ion Spectroscopy (CIS) in conjunction with high-Field Asymmetric Waveform Ion Mobility Spectrometry (FAIMS) to study the peptide bradykinin in its doubly protonated charge state ([bk+2H]2+). Using FAIMS we partially separate the electrospray ...

The Analog Formulation of Sparsity Implies Infinite Divisibility and Rules Out Bernoulli-Gaussian Priors

Michaël Unser, Arash Amini, Ulugbek Kamilov

Motivated by the analog nature of real-world signals, we investigate continuous-time random processes. For this purpose, we consider the stochastic processes that can be whitened by linear transformations and we show that the distribution of their samples ...

Cement distribution in vertebroplasties: imaging and simulation

Vincent Stadelmann

Prophylactic vertebroplasty, the percutaneous injection of bone cement into a weak vertebral body (VB), has been shown to reinforce the bone and possibly to minimize fracture risks. Cement leakage is still a common occurrence that can cause severe complica ...

Effects of streamflow variability on the vertical root density distribution of willow cutting experiments

Paolo Perona

The use of riparian tree cuttings for river rehabilitation relies on a good understanding of cutting survival and growth responses to environmental variables. A series of experiments aimed at studying the effects of water table fluctuation induced by strea ...

Application of complex-lag distributions for estimation of arbitrary order phase derivatives in digital holographic interferometry

Pramod Rastogi

This Letter proposes a method to estimate phase derivatives of arbitrary order in digital holographic interferometry. Based on the desired order, the generalized complex-lag distribution is computed from the reconstructed interference field. Subsequently, ...

Unsupervised adaptation to on-body sensor displacement in acceleration-based activity recognition

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Hamidreza Bayati

A common assumption in activity recognition is that the system remains unchanged between its design and its posterior operation. However, many factors can affect the data distribution between two different experimental sessions including sensor displacemen ...
