A wideband high-efficiency doherty power amplifier for LTE
(Institute of Electrical and Electronics Engineers Inc., 2023)
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 ...
Segmental resection for ureter urothelial carcinoma is safe as radical nephroureterectomy
(Elsevier, 2023)
Introduction & Objectives: Kidney-sparing surgery (KSS) seems inferior to radical nephroureterectomy (RNU) in recurrence-free survival (RFS). However, there is limited data regarding the potential influence of the location ...
Event-related alpha and beta phase-locking decreased in DLB and PDD compared to ADD during the visual oddball task
(Elsevier, 2023)
Introduction: Alzheimer's disease dementia (ADD), Parkinson's disease dementia (PDD), and dementia with Lewy bodies (DLB) are the most common types of dementia. In the last years, one of the essential questions is what are ...
Event-related brain oscillatory responses topographically differentiated between visual and auditory emotional stimuli
(Elsevier, 2023)
Previous EEG studies using emotional stimuli have successfully demonstrated that EEG-brain oscillation responses are sensitive to the valance and arousal of the stimulus. While the valance is represented by increased beta ...
Resting state electroencephalographic alpha rhythms predict and are sensitive to Alzheimer's disease mild cognitive impairment progression at a 6-month follow-up
(Elsevier, 2023)
Introduction: Patients with Alzheimer’s disease and mild cognitive impairment (ADMCI) suffer not only from severe cognitive deficits and disabilities in daily living but also from vigilance dysregulation reflected by ...
Reactivity of posterior cortical electroencephalographic alpha rythms during eyes opening in cognitively intact older adults and patients with dementia due to Alzheimer's and lewy diseases
(Elsevier, 2023)
Introduction: Patients with Lewy Bodies (DLB) and Parkinson’s disease dementia (PDD) suffer from vigilance dysregulation reflected by hypersomnolence, cognitive fluctuations, hallucinations, and sleep disorders. Therefore, ...
Swin transformer based siamese network for thermal and optical image registration
(IEEE-Institute of Electrical and Electronics Engineers, 2023)
The process of multi-modal image registration is fundamental in remote sensing and visual navigation applications. However, existing image registration methods that are designed for single modality images do not provide ...
