On the Capacity Comparison Between MIMO-NOMA and MIMO-OMA

open access: goldIEEE Access, 2016
Non-orthogonal multiple access (NOMA) has been shown in the literature to have a better performance than OMA in terms of sum channel capacity; however, the capacity superiority of NOMA over OMA has been only proved for single antenna systems, and the ...

The Performance Evaluation of NOMA for 5G Systems Using Automatic Deployment of Multi Users [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2022
Non-Orthogonal Multiple Access (NOMA) in the fifth generation (5G) system is one of the optimistic technologies for wireless radio access networks. Compared to orthogonal multiple accesses (OMA) reduce the spectral efficiency; NOMA provides the best ...

Hygiene and ritual in OMA’s domestic architecture

open access: yesDearq, 2022
Between 1984 and 1998, OMA produced a series of small-scale domestic projects. Rem Koolhaas uses ces maison as a tool for reflection, allowing him to explore the ‘hedonistic dimension’ that characterises the architecture of the Modern Movement. Among the

Calibration Method of Liquid-Crystal Spatial Light Modulator Based on a 1-D Phase Retrieval Algorithm

open access: yesIEEE Photonics Journal, 2023
Liquid-crystal spatial light modulator (LC-SLM) has been widely applied as a programmable digital device. However, the LC-SLM can only manipulate on light fields accurately under designated wavelengths since, when being uploaded a specific grayscale ...

Feasibility Study on Production of High-Purity Rhenium-185 by Nuclear Transmutation of Natural Tantalum

open access: yesJournal of Nuclear Engineering, 2023
Rhenium-186 (Re-186) has attracted attention as a medical isotope. The feasibility of producing Re-185, the raw material for Re-186, using a fast reactor was evaluated using a continuous energy Monte Carlo code.

Impact of Ovarian Endometrioma and Surgery on Reproductive Outcomes: A Single-Center Spanish Cohort Study

open access: yesBiomedicines, 2023
Anti-Müllerian hormone (AMH) and antral follicular count (AFC) decrease in women with ovarian endometrioma (OMA) and in vitro fertilization (IVF). In addition, these parameters drop even further when women with OMA undergo surgery.

Oocyte phenotype, genetic diagnosis, and clinical outcome in case of patients with oocyte maturation arrest

open access: yesFrontiers in Endocrinology, 2022
Backgroundoocyte maturation arrest (OMA) is currently one of the major causes of in vitro fertilization (IVF) failure, and several gene mutations were found to be associated with OMA.

Case Report and Literature Review: Ectopic Thyrotropin-Secreting Pituitary Adenoma in the Suprasellar Region

open access: yesFrontiers in Endocrinology, 2021
Ectopic thyrotropin-secreting pituitary adenoma (ectopic TSH-oma) is a rare disorder that is easily misdiagnosed in clinical work. We report one patient who presented with hyperthyroidism and a suprasellar mass.
