In this article, a novel study of the design and characterization of barium strontium titanate (BST) thick films produced by electrophoretic deposition (EPD) on flexible platinum foils is reported. Intended for sub-6 GHz radio frequency (RF) applications, a study on film and electrode thickness is conducted. First, a comparison of tunability and quality factor between different film thicknesses regarding frequency is performed. The Ba0.7Sr0.3TiO3 varactors demonstrate variable capacitance between 49% and 55% for frequencies from 500 MHz to 5 GHz. Afterward, the influence of electrode thickness on the capacitance and quality factor of the films are studied. The variable capacitance and the quality factor present a tradeoff regarding the parametric studies of film and electrode thicknesses. Lastly, a microstrip line is deposited over the BST thick film to simulate and measure the phase-shifting capabilities of the device. Using a one-tone measurement setup, the small-signal S-parameter measurements of the phase shifter are also presented, and the linearity is analyzed considering two different bias voltages, 0 and 10 V. For the first time, the BST thick films fabricated by EPD process are implemented and measured in the RF regime as a metal–insulator–metal capacitor and as a phase shifter circuit. published

To evaluate the efficacy and safety of ultrasound cycloplasty procedures (UCP) in patients with uncontrolled glaucoma. Prospective longitudinal study with UCP was performed by EyeOP1© probe with 8 s duration on 6 or 8 sectors, according to baseline intraocular pressure (IOP). Complete ophthalmic examination was performed pre- and post-operatively at 1st day, 1st week, 1st, 3rd, 6th, 9th and 12th months. UCP was repeated beyond 3rd month if IOP was > 21 mmHg, under maximum therapy, without major complications. Primary outcomes were complete (IOP reduction ≥ 20% or reduction in number of antiglaucomatous drugs and IOP ≥ 5 mmHg without occurrence of major complications) and qualified (IOP reduction ≥ 20% or reduction in number of antiglaucomatous drugs and IOP ≥ 5 mmHg) surgical success rates at 12 months. Secondary outcomes were mean IOP reduction, mean number of drugs reduction, rates of failure, number of repeated procedures, mean time to failure and occurrence of complications. Fourteen eyes of 13 patients (11 male) with advanced glaucoma (Hoddap classification) were included. Six were surgically naive. Mean age was 68.29 ± 10.66 years. Four eyes were treated in 8 sectors (28.5%). Patients were followed for 12 months after first UCP procedure. Overall surgical success was achieved in 92.9% at 6 months and in 100% of cases at 12 months. Mean IOP significantly reduced from 28.50 ± 7.61 mmHg to 13.79 ± 6.97 at 1 month, 17.36 ± 8.58 at 3 months, 17.79 ± 6.29 at 6 months, 16.3 ± 4.6 at 9 months and to 15.23 ± 5.09 at 12 months (p

In this paper, the samples preparation, experimental details, and characterization of the Electrophoretic Deposition (EPD) of a thick film Barium Strontium Titanate (BST) capacitor intended for radio-frequency applications are reported. With a bias voltage from 0 V to 20 V, the Ba 0.7 Sr 0.3 TiO 3 capacitor fabricated demonstrates 49% of tunability. The quality factor and the microwave (MW) loss tangent are calculated from 500 MHz to 5 GHz. Using an one-tone measurement setup, the small signal S-parameters measurements for the BST thick film capacitor are also presented by applying input signals from -20 dBm to 4 dBm. The linearity and loss tangent are analyzed considering a comparison of two different bias voltages, 0 V and 10 V. For the first time, the BST thick films fabricated with EPD are implemented and measured in the MW regime.

Two patients with refractory glaucoma followed in our ophthalmology department registered progression on left eyes (OS) despite best practice. Best corrected visual acuity (BCVA) was 9/10 and 8/10 and intraocular pressure (IOP) was above 20 mm Hg while under maximal hypotensive therapy. The procedure was performed under retrobulbar anaesthesia with second-generation EyeOp1probes. In follow-up, OS were hypotonic with registered IOP ≤5 mm Hg and revealed a 3/10 BCVA. The funduscopy showed one temporal and superior and another nasal and temporal choroidal detachments. The patients started oral steroids and interrupted all ocular hypotensive medication. After therapy, patients returned with normal rising OS IOPs and with totally reapplied choroids, accompanied by normalised BCVA. These two cases are proof of the possibility of transient choroidal detachment after a ultrasonic circular cyclocoagulation. While a very rare major vision-threatening complication, every ophthalmologist should remind it when sudden BCVA reductions occur after this procedure.

Introduction: Image processing of optical coherence tomography scans through binarization techniques represent a non-invasive way to separately asses and measure choroidal components, in vivo. In this review, we systematically search the scientific literature regarding binarization studies published so far. Methods: A systematic research was conducted at PubMed database, including English literature articles for all of the following terms in various combinations: binarization, choroid/al, enhanced depth spectral domain/swept source optic coherence tomography, and latest publications up to November 2018 were reviewed. Results: Thirty-seven articles were included and analyzed regarding studied disease, binarization method, studied variables, and outcomes. Most of the studies have focused on the more common retinal pathologies, such as age-related macular degeneration, central serous chorioretinopathy and diabetic retinopathy but binarization techniques have also been applied to the study of choroidal characteristics in ocular inflammatory diseases, corneal dystrophies and in postsurgical follow-up. Advantages and disadvantages of binarization techniques are also discussed. Conclusion: Binarization of choroidal images seems to represent a promising approach to study choroid subcomponents in an increasingly detailed manner. info:eu-repo/semantics/publishedVersion

In this paper, we propose an OpenFlow enabled Internet infrastructure, using virtual path slicing in an end-to-end path, so that any user connected to an OpenFlow network is dynamically allocated a corresponding right of way. This approach allows an interference-free path, from other traffic, between any two endpoints, on multiple autonomous systems, for a given application flow (e.g., WebHD Video Streaming). Additionally, we propose and implement an end-to-end quality of service framework for the Future Internet and extend the virtual path slice engine to support future Internet technologies such as OpenFlow. The proposed framework is evaluated in distinct multiple autonomous scenarios for a city with a population of 1 million inhabitants, emulating xDSL (Digital Subscriber Line), LTE (Long-Term Evolution) and Fibre networking scenarios. The obtained results confirm the suitability of the proposed architecture between multiple autonomous systems, considering both data and control traffic scalability, as well as resilience and failure recovery. Furthermore, challenges and solutions for experimentation in a large-scale testbed are described.

A 65-year-old man was referred to our department with complaints of blurred vision in the left eye. Funduscopic examination revealed areas of retinochoroidal atrophy along the retinal veins bilaterally and bone spicule pigmentation along the nasal and superior temporal venous branches, as well as macular oedema in the left eye. Fluorescein angiography, visual field test, optical coherence tomography and electrophysiological examination were performed, and results were compatible with the diagnosis of pigmented paravenous retinochoroidal atrophy (PPRCA). Treatment with topical dorzolamide and intravitreal bevacizumab in the left eye resulted in poor anatomical and visual response. There is scarce documentation of macular involvement with non-inflammatory unilateral cystoid macular oedema in PPRCA in the literature. Further investigation is required to elucidate the pathogenesis of PPRCA and to properly manage these patients.

Achieving ever-growing Quality of Service (QoS) requirements for business customers is a major concern over the current Internet. However, presently, its architecture and infrastructures are inflexible to meet the demand of increased QoS requirements. OpenFlow, OF-Config (OpenFlow Configuration and Management protocol), and OVSDB (Open vSwitch Database Management protocol) protocols are well-known software defined networking (SDN) technologies for the Future Internet, enabling flexibility by decoupling the control plane from networking devices. In this paper, we propose a QoS framework using the SDN technologies and test the framework in failure-conditions using single and multiple autonomous system scenarios of the current Internet. We show that an effectively high QoS can be achieved for business customers using our framework.

This article describes the UNIFAES, Unified Finite Approach Exponential-type Scheme for convective-diffusive fluid transport equations, including the treatment of Neumann boundary conditions. To reduce the computing time, UNIFAES allows the use of Patankar's power-law approximation rule. The scheme is subjected to the Smith and Hutton test problem, where it is compared to central differencing, the exponential scheme, and the locally analytic differencing scheme (LOADS). Finally, the scheme is applied to the problem of natural convection within a square porous cavity heated from below, considering single-cell and multiple-cell solutions of this porous Benard-like convection problem.

This paper presents an architecture prototype, named Web Server with Service Differentiation, able to provide QoS to different classes of services. With the implemented prototype, an admission control algorithm, named connection reservation algorithm is proposed and compared to the negotiation algorithm. The results of the performance evaluation have showed both algorithms met proportionally a higher number of high priority class (Class 1) requests in relation to low priority class (Class 2), although the connection reservation algorithm fitted all workload variance better. The connection reservation algorithm can be extended to the Web, where workload dynamic characteristics predominate.

We analyzed the first 96 patients tested for HIV resistance to antiretroviral therapy in three Brazilian states. The HIV-1 reverse transcriptase (RT) and protease (PR) were sequenced by using the ABI ViroSeq system. The drugs previously used for each patient were recorded and correlated with the mutations found in the samples. Viral load (VL) and CD4 count were also recorded. Only one patient had the wild type sequence. The most prevalent mutations were: 184V (59%), 41L (47.9%), 63P (53%), 215Y (50%), 36I (46%), 10I (35%), 67N (42%), 77I (37%), 90M (36%) and 210W (33%). A positive correlation between the number of previously used ARVs and the number of mutations was observed (p

Media use cases for emergency services require mission-critical levels of reliability for the delivery of media-rich services, such as video streaming. With the upcoming deployment of the fifth generation (5G) networks, a wide variety of applications and services with heterogeneous performance requirements are expected to be supported, and any migration of mission-critical services to 5G networks presents significant challenges in the quality of service (QoS), for emergency service operators. This paper presents a novel SliceNet framework, based on advanced and customizable network slicing to address some of the highlighted challenges in migrating eHealth telemedicine services to 5G networks. An overview of the framework outlines the technical approaches in beyond the state-of-the-art network slicing. Subsequently, this paper emphasizes the design and prototyping of a media-centric eHealth use case, focusing on a set of innovative enablers toward achieving end-to-end QoS-aware network slicing capabilities, required by this demanding use case. Experimental results empirically validate the prototyped enablers and demonstrate the applicability of the proposed framework in such media-rich use cases.

Future networks including the Fifth Generation (5G) and beyond mobile networks shall manage, control and orchestrate the new services for users especially vertical sectors, thereby they shall maximize the potential of 5G infrastructures and their services. Network slicing has emerged as a major new networking paradigm for meeting the diverse requirements of various vertical businesses in virtualized and softwarised 5G networks. SliceNet is a project of the EU 5G Infrastructure Public Private Partnership (5G PPP) and focuses on network slicing as a cornerstone technology in 5G networks. This article describes how the SliceNet Control Plane shall evolve to meet the end-to-end needs of many different vertical businesses. SliceNet Control Plane shall span across multiple administrative domains, by integrating different technologies in each involved segments (RAN, MEC, CN, inter-connectivity). Moreover, SliceNet Control Plane is able to allow verticals to plug their own control logic on top of provisioned slices and specialize their services characteristics while optimizing the use of shared resources, providing dynamic configuration, dynamic management, resource isolation and scalability.

Communications for emergency services have traditionally been provided by dedicated radio technologies, like the TETRA system. However the need for more efficient mobile communications is gaining popularity in these scenarios due to extreme requirements by means of availability, price and spectrum usage. This trend will be further accentuated in the coming years with the appearance of 5G systems that promise better figures in almost all the Key Performance Indicators (KPIs). LTE can provide many of the functionalities required by emergency services and is currently being evolved towards the 5G era by incorporating heterogeneous networking, over the top applications, network function virtualisation and more. The Q4Health project focuses on the preparatives for market introduction of eHealth video applications for first responders based on LTE technology. This preparation includes the investigation of advanced LTE programmability features and the design and execution of several novel experiments in order to optimise the communications for this platform.
