Graphene exhibits unusual electronic properties, caused by a linear band structure near the Dirac point. This band structure is determined by the stacking sequence in graphene multilayers. Here we present a novel method of microscopically controlling the band structure. This is achieved by epitaxy of graphene on 3C-SiC(111) and 3C-SiC(100) thin films grown on a 3D microfabricated Si(100) substr...

This paper deals with a method of the radiation pattern determination of the directional antennas. The method combining both the functional minimization method and the Fourier iterative algorithm is based on the phaseless near-field measurement on two plane surfaces. The method is used for a reconstruction of the phase distribution on the aperture of the measured antenna, and for the determinat...

Graphene oxides (GOs) have emerged as precursors offering the potential of a cost-effective and large-scale production of graphene-based materials. Despite that their intrinsic fluorescence property has already brought interest of researchers for optical applications, to date, refractive-index modulation as one of the fundamental aspects of optical properties of GOs has received less attention....

A b st ra ct Background: The management of acute intracranial hypertension refractory, to the medical management, remains a challenging endeavour. Mortality and morbidity rates remain high despite optimal medical management. Decompressive craniectomy has been proposed as an effective treatment for patients who have raised intracranial pressure (ICP) refractory, to the medical management. This s...

Telecommunication networks are converging towards an all-IP paradigm that integrates a broad set of value-added services. In this context, the IP Multimedia Subsystem (IMS) is being developed by the 3GPP as a key element to achieve the convergence. Another development is that multiparty services are nowadays acquiring an increasing interest from the industry. In this respect, network multicast ...

OBJECTIVE To study the effect of hyperbaric oxy gen (HBO) treatment of severe brain injury. METHODS Fifty-five patients were divided into a treatment group (n=35 receiving HBO therapy) and a control group (n=20 receiving dehydrating, cortical steroid and antibiotic therapy) to observe the alteration of clinic GCS (Glasgow Coma Scale), brain electric activity mapping (BEAM), prognosis and GOS ...

Corporations increasingly consider sustainability as an important goal and set net zero carbon emissions targets, consequently looking towards their electricity procurement to achieve them. Guarantees of Origin (GOs) are widely used insurances for the renewability supplies proofs compliance renewable standards; however, they suffer from structural problems. Their transactional history cannot di...

BACKGROUND AND PURPOSE Current imaging does not permit quantification of neural injury after traumatic brain injury (TBI) and therefore limits both the development of new treatments and the appropriate counseling of patients concerning prognosis. We evaluated the utility of magnetization transfer ratio (MTR) and proton MR spectroscopy in identifying patients with neuronal injury after TBI. ME...

PURPOSE The direct effects of galacto-oligosaccharides (GOS), including Vivinal® GOS syrup (VGOS) and purified Vivinal® GOS (PGOS), on the epithelial integrity and corresponding interleukin-8 (IL-8/CXCL8) release were examined in a Caco-2 cell model for intestinal barrier dysfunction. To investigate structure-activity relationships, the effects of individual DP fractions of VGOS were evaluated....

In the last few years, there has been enormous interest in graphene oxide (GO) for its wide variety of applications[1]. However, for any medical application, the immune system-impact of GO still remain to be fully understood. Moreover, the modulation of immune cells mediated by nanomaterials could be interesting also in immunotheraphy applications[2]. Indeed, nanomaterials and more in general n...
