Increased performance in genetic manipulation by modeling the dielectric properties of the rodent brain

Genetic approaches to control DNA expression in different brain areas have provided an excellent system to characterize gene function in health and disease of animal models. With respect to others, in utero electroporation of exogenous DNA into progenitor ...

Estimation of Relative Position and Coordination of Mobile Underwater Robotic Platforms through Electric Sensing

Auke Ijspeert, Yannick Morel, Mathieu Porez

In the context of underwater robotics, positioning and coordination of mobile agents can prove a challenging problem. To address this issue, we propose the use of electric sensing, with a technique inspired by weakly electric fishes. In particular, the app ...

Application of the time reversal of electromagnetic fields to locate lightning discharges

Marcos Rubinstein, Nicolas Mora Parra

In this paper, we propose a new method for locating lightning discharges. The proposed method is based on the time reversal technique introduced for acoustics in the early 1990s. By analogy to the derivations in acoustics, equations for the focusing of ele ...

Multi-physics model of an electric fish-like robot: numerical aspects and application to obstacle avoidance

Auke Ijspeert, Mathieu Porez

The paper deals with the modeling of a fishlike robot equipped with the electric sense, suited to study sensorimotor loops. The proposed multi-physics model merges a swimming dynamic model of a fish-like robot with an electric model of an embedded electrol ...

Electromagnetic Environment Associated with Lightning Strikes to Tall Strike Objects

Seyed Abbas Mosaddeghi

The study of the lightning interaction with tall strike objects has attracted considerable attention of lightning researchers lately. Many lightning measurements including current and associated electromagnetic fields were recently made all over the globe ...

Third-Order Susceptibility of Silicon Crystals Measured with Millimeter-Wave Gyrotron

Jean-Philippe Hogge, Markus Siegrist

We investigate experimental dependence of the third harmonic generation efficiency in the n-type Si crystals on the geometrical dimensions of the sample, polarization and power of the fundamental wave. The efficiency increases monotonically with the rise o ...

On the Measurement and Calculation of Horizontal Electric Fields From Lightning

Marcos Rubinstein, Abdolhamid Shoory

In this paper, we discuss two issues related to the measurement and calculation of the horizontal electric fields from lightning. On the one hand, there is an inherent difficulty inmeasuring the horizontal electric field component from lightning because of ...

Structural Property and Electric Field Response of a Single Perovskite PbTiO3 Nanowire Using Micro X-ray Beam

Nava Setter, Jin Wang

The structural property and electric field response of a single perovskite PbTiO3 nanowire were investigated by means of synchrotron X-ray diffraction (XRD) with a micro X-ray beam. XRD 0-20 patterns and Raman spectra confirmed the formation of the perovsk ...

Lightning Electromagnetic Fields at Very Close Distances Associated with Lightning Strikes to the Gaisberg Tower

Marcos Rubinstein, Davide Pavanello, Pierre Zweiacker, Abdolhamid Shoory, Seyed Abbas Mosaddeghi

In this paper we present and discuss measurements of electric (vertical and radial) and magnetic fields from leaders and return strokes associated with lightning strikes to the 100 m tall Gaisberg tower in Austria obtained in 2007 and 2008. The fields were ...

Validity of Simplified Approaches for the Evaluation of Lightning Electromagnetic Fields above a Horizontally Stratified Ground

Abdolhamid Shoory, Abdenabi Mimouni

We review in this paper simplified analytical expressions derived by Wait using the concept of attenuation function for the analysis of the propagation of lightning radiated electromagnetic fields over a horizontally stratified ground. Considerations regar ...
