1. Design and Simulation of Broadband Horn Nanoantennas for Nanophotonic Applications
Abstract Optical plasmonic nanoantennas have proven useful in nanoplasmonic applications, paving the way for more efficient wireless optical communications. In this work, we propose a parametric study of a plasmonic horn nanoantenna in flat H sectorial format and beveled horn, both designed to radiate in the three wavelengths of optical communications: [850

3. Evaluation of 10-minute post-injection 11C-PiB PET and its correlation with 18F-FDG PET in older adults who are cognitively healthy, mildly impaired, or with probable Alzheimer’s disease
Objective: Positron emission tomography (PET) allows in vivo evaluation of molecular targets in neurodegenerative diseases, such as Alzheimer’s disease. Mild cognitive impairment is an intermediate stage between normal cognition and Alzheimer-type dementia. In vivo fibrillar amyloid-beta can be detected in PET using [11C]-labeled Pittsburgh compound B (11C

4. Revisiting the Concept of Non- and Minimally Invasive Interventions in Early Glottic Cancer – Part II: Single Therapy Should be Favored over the Combination of Transoral Laser Microsurgery and Radiotherapy, Regarding the Postinterventional Voice Quality
Abstract Introduction Early glottic cancer (EGC) is associated with a high cure rate. Hence, patients and physicians also focus on the impact of the proposed treatment on the speaking function of the preserved larynx. Objectives The present study assessed the impact of single-modality treatment (transoral laser microsurgery [TLM], or radiotherapy) or combi

5. Metabolic Syndrome and Risk of Cardiovascular Diseases in Female Breast Cancer Survivors
Abstract Background The implementation of intensive therapy protocols increases the probability of adverse events in patients with breast cancer (BC). Components of metabolic syndrome (MS) are among these events. Objective To verify the prevalence of MS and cardiovascular disease (CVD) risk in female BC survivors. Materials and Methods This is a descri

9. A Parametric Study of Inductive SWIPT Systems Assisted by Metamaterial Using Virtual Magnetic TL-Based Channel Modeling
Abstract This paper presents a general methodology based on the description of the inductive channel as virtual magnetic transmission-lines (VMGTLs). In comparison with other existing methods, VMGTL approach presents a better physical insight of the channel behavior since the model correctly preserves the energy flow between the transmitting and receiving co

10. Analysis of the Resonator Element in Different Positions in the Circular Patch Microstrip Antenna
Abstract In this article, a circular patch microstrip antenna with a metamaterial resonator for 4G applications is proposed. For the design of the circular antenna patch, an approximate calculation was performed. The circular resonator is inserted into the patch for some antennas, in different positions for a parametric study. When incorporating the resonato
