Beam squint effect in multi-beam mmWave massive MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
In multicarrier wideband millimeter-wave (mmWave) communications, as the size of antenna array increases, as in massive multiple-input multiple-output (MIMO), an additional propagation delay of the electromagnetic wave at ...
The impact of varicocele repairon conventional semen paramaeters in infertile men: A meta-analysis using pre- and post-operative data.
(Elsevier Science Inc., 2022)
Objective Varicocele is a widespread disorder affecting about 15% of the normal male population, 25% of men with abnormal semen analysis, and 35-40% of primary infertile men. There are few systematic reviews and meta-analyses ...
Effect of varicocele repair on conventional sperm parameters in infertile patients with clinical varicocele: A systematic review and metaanalysis.
(Elsevier Science Inc., 2022)
Objective Varicocele is present in almost 35-40% of men presenting with primary infertility. Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on ...
Physician and patient preferences for oral anticoagulation therapy decision-making in atrial fibrillation: Results from a national best-worst scaling survey in Turkey (PREF-AF)
(Elsevier Science Inc., 2022)
Objectives Cost-utility modeling informs reimbursement decisions and is based on the premise that health outcome improvements can be expressed as disease-independent utility scores. Previous cost-utility analyses of ...
Inter-HAP based geometrical 3-D channel model operating at 28 to 60 GHz for future 6G non-terrestrial networks
(Institute of Electrical and Electronics Engineers Inc., 2023)
This paper presents a geometrical 3-D channel model for stationary inter-high altitude platform (HAP) systems operating at millimeter wave (mmWave) frequency bands for the future 6G non-terrestrial networks (NTNs). The ...

This article describes a broadband Doherty power amplifier designed with a class AB and class C PA that is suitable for LTE Band-7 and Wi-Fi applications. The output matching network is theoretically analyzed, with emphasis ...
Chemogenetic tools and genetic biosensors in redox biology: Probing Hyper7 signals in specific cellular locales
(Elsevier Science Inc., 2023)
H2O2 is one of the most studied reactive oxygen species (ROS) in redox biology because of its critical role in oxidant-dependent signaling pathways. Conventional approaches apply exogenous H2O2 on cells and tissues, which ...
Estimating multi-dimensional sparsity level for spectrum sensing
(Institute of Electrical and Electronics Engineers Inc., 2023)
Identifying spectrum opportunities is a crucial element of efficient spectrum utilization for future wireless networks. Spectrum sensing offers a convenient means for revealing such opportunities. Studies showed that usage ...
rs-fMRI analysis using spatio-temporal sparse convolutional neural networks
(Institute of Electrical and Electronics Engineers Inc., 2022)
Neuropsychiatric diseases such as Autism Spectrum Disorder (ASD) and Schizophrenia cause various behavioral and communication dysfunctions in human life. Resting state functional magnetic resonance imaging (rs-fMRI) is ...
