In this paper, with the aid of mutual information and generalized mutual information (GMI) capacity analyses, it is shown that the geometrically shaped APSK that mimics an optimal Gaussian distribution with equiprobable signaling together with the corresponding gray-mapping rules can approach the Shannon limit closer than conventional quadrature amplitude modulation (QAM) at certain range of FE...
The Global Meningococcal Initiative (GMI) has recently considered current issues in Middle Eastern and African countries, and produced two recommendations: (i) that vaccination of attendees should be considered for some types of mass-gathering events, as some countries mandate for the Hajj, and (ii) vaccination of people with human immunodeficiency virus should be used routinely, because of inc...
اثر امپدانس مغناطیسی (mi) به صورت تغییرات امپدانس الکتریکی رسانای مغناطیسی در حضور میدان مغناطیسی متغیر تعریف می شود. بررسی این اثر از سال 1994 پس از گزارش موهری و همکارانش مبنی بر وجود اثر امپدانس مغناطیسی در سیم کبالت پایه، به طور جدی آغاز شد. امپدانس مغناطیسی برزگ نامتقارن(agmi) در بهبود هرچه بیشتر حسگرهایی که برحسب جملههای خطی بودن و میزان حساسیت به فعالیت در آمده اند بسیار مهم است. در ...
PURPOSE To determine if quantifiable morphometric signs of retinopathy occur in the Zucker diabetic fatty rat (ZDF/Gmi-fa, formerly designated ZDF/Drt), a partially inbred strain in which the genetic propensity for diabetes is only expressed in obese males. METHODS Retired diabetic (ZDF/Gmi-fa) and control lean Zucker (fa/+) breeder rats were examined for quantifiable evidence of microvascula...
In early phase clinical trials of cytotoxic drugs in oncology, the efficacy is typically evaluated based on the tumor shrinkage. However, this criterion is not always appropriate for more recent cytostatic agents, and alternative endpoints have been proposed. The growth modulation index (GMI), defined as the ratio between the times to progression in two successive treatment lines, has been prop...
Voronoi constellations (VCs) are considered as an effective geometric shaping method due to their high power efficiencies and low complexity. In this paper, the performance of 16- 32-dimensional VCs with a variety spectral transmitted in nonlinear fiber channel investigated. Both single-channel wavelength-division multiplexing systems for transmission VCs, well different signal processing schem...
BackgroundTranscutaneous auricular vagus nerve stimulation (taVNS) has been investigated regarding its therapeutic properties in several conditions such as epilepsy, migraine and major depressive disorder was shown to access similar neural pathways invasive stimulation. While the nerve's role gut motility is physiologically established, effect of taVNS scarcely humans yielded conflicting result...
− The Laboratory of Biometrology of PUCRio has been developing magnetic field transducers to be used in biomedical applications. Investigations recently accomplished indicate the possibility of a new research line, which considers the changes in the phase characteristics of Giant Magnetoimpedance (GMI) sensors due to varying low-intensity magnetic fields. In spite of being less explored in the ...
