Can Oscillatory Alpha-Gamma Phase-Amplitude Coupling be Used to Understand and Enhance TMS Effects?
2019
Recent applications of simultaneous scalp electroencephalography (EEG) and transcranial magnetic stimulation (TMS) suggest that adapting stimulation to underlying brain states may enhance neuroplastic effects of TMS. It is often assumed that longer-lasting effects of TMS on brain function may be mediated by phasic interactions between TMS pulses and endogenous cortical oscillatory dynamics. The mechanisms by which TMS exerts its neuromodulatory effects, however, remain unknown. Here, we discuss evidence concerning the functional effects on synaptic plasticity of oscillatory cross-frequency coupling in cortical networks as a potential framework for understanding the neuromodulatory effects o…
Plant Specialized Metabolites in Hazelnut (Corylus avellana) Kernel and Byproducts: An Update on Chemistry, Biological Activity, and Analytical Aspec…
2019
Abstract Corylus avellana (hazelnut) is one of the most popular tree nuts on a worldwide basis. The main products of C. avellana are kernels, a nutritious food, with a high content of healthy lipids, contained in a hard shell. In recent years, along with the ongoing research carried out on hazelnut kernels, a growing interest has been addressed to the hazelnut byproducts including hazelnut skin, hazelnut hard shell, and hazelnut green leafy cover as well as hazelnut tree leaf. These byproducts deriving from the roasting, cracking, shelling/hulling, and harvesting processes have been found as a source of “phytochemicals” with biological activity. The aim of this review is to provide a compre…

On the use of the EMI for the health monitoring of bonded elements
2014
The low weight, robustness and fatigue resistance of adhesive joints make them suitable for structural joints. A fully developed nondestructive evaluation technique however is needed to monitor and assess the quality of bonded joints. In the present paper the application of the electromechanical impedance (EMI) technique is proposed. In the EMI method a piezoelectric transducer (PZT) is attached to the structure of interest. The high sensitivity and low power consumption make the EMI method feasible for real time structural health monitoring. In this study we investigated the sensitivity of the electromechanical response of a PZT to the curing and the quality of the adhesive used for bonded…
Active lighting applied to three-dimensional reconstruction of specular metallic surfaces by polarization imaging
2006
International audience; In the field of industrial vision, the three-dimensional inspection of highly reflective metallic objects is still a delicate task. We deal with a new automated three-dimensional inspection system based on polarization analysis. We first present an extension of the shape-from-polarization method for dielectric surfaces to metallic surfaces. Then, we describe what we believe to be a new way of solving the ambiguity concerning the normal orientation with an active lighting system. Finally, applications to shape-defect detection are discussed, and the efficiency of the system to discriminate defects on specular metallic objects made by stamping and polishing is presente…
Étude d'inclusions végétales dans des tessons de poterie ou des matériaux de construction
2005
Vegetal inclusions embedded in clayey materials (cob, ceramic, mudbrick) are investigated by using impregnation of the porous material with a fluorescent polymer. The micro-casting of the porosity is exploited by following two ways. Sections of the treated samples are examined under UV-light, showing vegetal structures amenable to a botanical identification and quantification. Moreover, micro-casts embedded in the mineral matrix have been successfully sorted. This new application is a tool to study archaeological samples previously not amenable to the work of archaeobotanists and to expand their field of investigation.
An Ethical Investments Evaluation for Portfolio Selection
2004
The Socially Responsible Investing (SRI) is an assets allocation, whose aim is to maximize not only the portfolio expected return but the benefits for a consumer who as a whole operates according to the ethical principles. The wealth of a market economy is to cross the different ethical identities of families, of enterprises, of banks, in order to improve the allocation of the resources for a sustainable development. In this paper, we aim at describing the portfolio selection realized on the basis of the ethical principles - positive /negative, inclusionary/exclusionary - of an investor. The first part of this paper describes Socially Responsible Investing (SRI) and ethical funds market in …
Lääkintälaitteiden kyberturvallisuuden standardit ja testaaminen
2017
Tietotekniikkaa sisältävät lääkintälaitteet pitävät meidät hengissä, jos kehomme pettää. Esimerkiksi ostoskeskuksissa olevat älykkäät defibrillaattorit antavat maallikoillekin mahdollisuuden antaa tehokasta ensiapua sydänkohtaukseen. Tietotekniikan käyttäminen lääkintälaitteissa tuo mahdollisuuksien lisäksi uhkia. Tässä tutkielmassa perehdytään siihen, miten standardit ja testaaminen edistävät kyberturvallisuutta, uhkien torjumista. Ensin tehdään katsaus kirjallisuuteen ja standardeihin ja sitten kytketään tieto käytäntöön testaamalla potilasmonitoria kirjallisuuden pohjalta. Tulos oli, että tutkittava potilasmonitori oli hyvin avoin fyysisen käyttöliittymän kautta. Esimerkiksi potilastiedo…
An Innovative Coupling Solution for Power Line Communication in MV Electrical Networks
2019
One of the main problems in the diffusion of power line communication (PLC) in medium voltage (MV) networks is the need of a dedicated PLC coupler to be installed all over the network. To avoid this problem, the authors have studied, prototyped and patented an innovative PLC coupling solution which uses electrical elements embedded in most of the switchgears already installed in MV networks, i.e. the capacitive dividers of the voltage detecting systems (VDS). The new solution prototype is described in this paper, highlighting the advantages in terms of a significant reduction of both direct costs of equipment and infrastructures and indirect costs of installation and service interruption. T…
Simulation of a Power Line Communication System in Medium and Low Voltage Distribution Networks
2011
The aim of the paper is to study the influence of the power transformer on signal transmission in the case of a power line communication (PLC) system in a overhead Medium Voltage (MV) power network. A model of the PLC system was carried out by means of the Simulink® software. A distributed parameter MV overhead line, two power transformers, the signal coupling networks and the receiving and transmitting line coupling interface of a ST7540 FSK powerline transceiver were included in the model. The performances of the complete PLC communication system are evaluated for different line lengths by means of the attenuation computed as ratio between the received and transmitted voltage signals.
