Impact of surfaces on the optical properties of GaAs nanowires

The effect of surfaces on the optical properties of GaAs nanowires is evidenced by comparing nanowires with or without an AlGaAs capping shell as a function of the diameter. We find that the optical properties of unpassivated nanowires are governed by Ferm ...

Biomechanical Evaluation of Human Skin on Various Anatomical Sites (Semester Project)

Lee Ann Laurent-Applegate, Salim Elias Darwiche

Measures of skin elasticity, immediate retraction and distention as well as pigmentation and erythema will be conducted on various anatomical sites to compile a profile of skin properties. ...

A micro CT technique to measure peri-implant micromotions of cementless femoral stems

Dominique Pioletti, Alexandre Terrier, Miguel Gortchacow

The interfacial micromotion is closely associated to the long-term success of cementless hip prostheses. Various techniques have been proposed to measure them, but only a limited number of points over the stem surface can be measured simultaneously. In thi ...

Tightening force and torque of nonlocking screws in a reverse shoulder prosthesis

Dominique Pioletti, Alexandre Terrier, Alain Farron, Francesco Merlini, Miguel Gortchacow, Stephanie Kochbeck

Background. Reversed shoulder arthroplasty is an accepted treatment for glenohumeral arthritis associated to rotator cuff deficiency. For most reversed shoulder prostheses, the baseplate of the glenoid component is uncemented and its primary stability is p ...

Improved Similarity Measures for Small Sets of Spike Trains

Wulfram Gerstner, Richard Naud, Joao Emanuel Felipe Gerhard, Skander Mensi

Multiple types of measures have been developed to measure the similarity between two spike trains. These were extensively used to classify neuron responses according to stimuli and to validate mathematical models that predict the spike times. Here we analy ...

Numerical validation of a new method to assess aortic pulse wave velocity from a single recording of a brachial artery waveform with an occluding cuff

Nikolaos Stergiopoulos, Philippe Reymond, Bram Trachet, Patrick Segers

Recently a new method has been proposed as a tool to measure arterial pulse wave velocity (PWV), a measure of the stiffness of the large arteries and an emerging parameter used as indicator of clinical cardiovascular risk. The method is based on measuremen ...

Influence of national rockfall hazard guidelines on land-use planning

Vincent Labiouse, Jacopo Maria Abbruzzese

Basic principles of living with natural risks are established according to the experience of each country in facing this problem. The strategies adopted for evaluating rockfall hazards and for reducing the potential risk they represent may therefore lead t ...

NMR Properties of Human Median Nerve at 3 T: Proton Density, T1, T2, and Magnetization Transfer

Giulio Gambarota

Purpose: To measure the proton density (PD), the T1 and T2 relaxation time, and magnetization transfer (MT) effects in human median nerve at 3 T and to compare them with the corresponding values in muscle. ...

Measurement of printer MTFs

Albrecht Johannes Lindner

In this paper we compare three existing methods to measure the Modulation Transfer Function (MTF) of a printing system. Although all three methods use very distinct approaches, the MTF values computed for two of these methods strongly agree, lending credib ...

Contextual Modulation and Gestalt

Michael Herzog, Bilge Sayim

The perception of a stimulus can strongly be modified by its spatial context. For example, when a vernier stimulus is flanked by two lines, performance deteriorates compared to a vernier without flanks. This is usually explained by local interactions, such ...
