Data fusion method for Earth Observation Satellite Data based on Wavelet MRA
Journal of the Visualization Society of Japan, 2002 A method for interpolation of multi-sensor satellite images based on Multi-Resolution Analysis (MRA) is proposed. The proposed method is examined by using TMI (TRMM Microwave Imager) / SST (Sea Surface Temperature) and VIRS (Visible Infrared Scanner) / SST images as low and high spatial resolution images, respectively.

Continuous-time adaptive control applied to rf amplifier linearization [PDF]
, 1994 A new approach to the RF power amplifier linearization problem is presented. The proposed solution applies non-linear theories (Lyapunov direct method) to adaptive filtering in order to improve the linearity of the RF amplifiers.

A Hybrid H∞-MRAS Observer of Wind Turbines Conversion Systems based on DFIG
Algerian Journal of Renewable Energy and Sustainable Development, 2022 This study proposes the robust sensor-less advanced frequency control (robust H∞ control) of the system of wind turbine based on a doubly fed induction generator (DFIG), the power exchange between the machine stator and the network is achieved by applying the rotor of DFIG via a bidirectional converter.

Jet-driven and jet-less fireballs from compact binary mergers [PDF]
, 2017 During a compact binary merger involving at least one neutron star, a small fraction of the gravitational energy could be liberated in such a way to accelerate a small fraction (~ 10^-6) of the neutron star mass in an isotropic or quasi-isotropic way. In

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe
