A simulation model for wideband MIMO vehicle-to-vehicle fading channels in T-junction propagation environments

2010

In this paper, we propose a high-performance simulation model for wideband multiple-input multiple-output (MIMO) vehicle-to-vehicle (V2V) fading channels in T-junction propagation environments. The so-called Riemann sum method (RSM) is applied for the parametrisation of the simulation model. Furthermore, the statistical properties of the wideband MIMO V2V channel simulation model, such as the space-time-frequency cross-correlation function (STF-CCF), the two-dimensional spatial cross-correlation function (2D spatial CCF) and the temporal auto-correlation function (ACF) are studied. Finally, the high accuracy of the proposed simulation model is demonstrated by comparing the correlation prope…

Magnetic dichroism in angle-resolved hard x-ray photoemission from buried layers

2011

This work reports the measurement of magnetic dichroism in angular-resolved photoemission from in-plane magnetized buried thin films. The high bulk sensitivity of hard x-ray photoelectron spectroscopy (HAXPES) in combination with circularly polarized radiation enables the investigation of the magnetic properties of buried layers. HAXPES experiments with an excitation energy of 8 keV were performed on exchange-biased magnetic layers covered by thin oxide films. Two types of structures were investigated with the IrMn exchange-biasing layer either above or below the ferromagnetic layer: one with a CoFe layer on top and another with a Co${}_{2}$FeAl layer buried beneath the IrMn layer. A pronou…

Wind accretion in the massive X-ray binary 4U 2206+54: abnormally slow wind and a moderately eccentric orbit

2006

Massive X-ray binaries are usually classified depending on the properties of the donor star in classical, supergiant and Be X-ray binaries. The massive X-ray binary 4U 2206+54 does not fit in any of these groups, and deserves a detailed study to understand how the transfer of matter and the accretion on to the compact object take place. To this end we study an IUE spectrum of the donor and obtain a wind terminal velocity (v_inf) of ~350 km/s, which is abnormally slow for its spectral type. We also analyse here more than 9 years of available RXTE/ASM data. We study the long-term X-ray variability of the source and find it to be similar to that observed in the wind-fed supergiant system Vela …

Focal Cortical Lesions Induce Bidirectional Changes in the Excitability of Fast Spiking and Non Fast Spiking Cortical Interneurons

2014

A physiological brain function requires neuronal networks to operate within a well-defined range of activity. Indeed, alterations in neuronal excitability have been associated with several pathological conditions, ranging from epilepsy to neuropsychiatric disorders. Changes in inhibitory transmission are known to play a key role in the development of hyperexcitability. However it is largely unknown whether specific interneuronal subpopulations contribute differentially to such pathological condition. In the present study we investigated functional alterations of inhibitory interneurons embedded in a hyperexcitable cortical circuit at the border of chronically induced focal lesions in mouse …

Thermomineral waters of Greece: geochemical characterization

Regarding TDS concentrations collected waters can be subdivided into low salinity (up to 1.5 g/L) brackish (up to 20 g/L) and saline (up to 43 g/L). The medium high salinities can be justified by mixing with sea water and/or strong waterrock interaction processes. Isotope composition of O and H ranges from 12.7 to +2.7 ‰ SMOW and from 91 to +12 ‰ SMOW respectively and is generally comprised between the Global Meteoric Water Line and the East Mediterranean Meteoric Water Line. Only few water samples show a positive shift for δ18O possibly related to high temperature waterrock interaction processes.

Moreover the majority of them is found along the coast as well as in islands of the Aegean Sea and thus thermal water is often brackish to saline due to marine intrusion into costal aquifer. In the present study almost 300 thermal and cold mineral water samples were collected along the Hellenic territory with their physicochemical parameters (temperature pH electrical conductivity and Eh) and the amount of bicarbonates (titration with 0.1N HCl) being determined in situ. Additionally gases found either in free or dissolved phase were sampled. Both water and gas samples were analysed at the INGVPa laboratories for major ions (Ion Chromatography) silica (Inductively Coupled Plasma Optical Emission Spectrometry) chemical composition of free and dissolved gases (Gas Chromatography) water isotopes (O and H) and carbon and helium isotopes of free and dissolved gases (Mass Spectrometry). The temperature of the investigated waters ranges from 6.5 to 98°C pH from 1.96 to 11.98 whilst Total Dissolved Solids (TDS) from 0.06 to 43 g/L.

Determinación de la edad de un extranjero indocumentado : A propósito de la sentencia de la audiencia provincial de barcelona, de 24 de enero de 2020

2021

In recent years, immigration of minors has increased, which means that administrations establish a differentiated treatment for this sector of immigration due to the fact that they are minors; There are many aspects to take into account in these cases, including verifying the minority age, a fact that is more complicated when it comes to adolescents. This is what is analyzed by the Judgment of the Provincial Court of Barcelona, of January 24, 2020, which confirms the Resolution of the General Directorate of Attention to Children and Adolescents, which agreed to the closure of the homelessness file and the admission of the plaintiff in a Protection Center until the verification of their pers…

Getting married or entering into a partnership : the patrimonial issues of choice in french law

2021

In French law, there are only two models of couples between which a choice is really possible to organize their patrimonial relationships: partnership or marriage. But, if the couple intends to organize a transfer of assets between companions both during the union and in case of death, it is definitely marriage that offers more possibilities than partnership. Often, young French couples, who do not wish to marry, either not at the begining of their relationship or not at all, have the idea that, if marriage organizes a legal protection of the couple, the partners have the possibility to provide conventionally equivalent protection. In fact, this idea is wrong.

Protection of the surviving spouse in French law

2021

While French inheritance law has recently sought to give everyone more freedom to anticipate the transmission of their estate, it still guarantees to the children a reserved portion in his estate. This guarantees the deceased?s children a minimum share in his/her estate. However, the mechanisms protecting this reserve are subject to legal adjustments when spouses wish to organize the protection of the couple?s survivor, either by submitting to a conventional matrimonial regime or by giving themselves gifts that improve the legal succession of the spouse. This ensures a balance between the protection of the spouse and that of the compulsory heirs. Not seeming to be satisfied, several famous …
