Graph signal sampling has been widely studied in recent years, but the accurate signal models required by most of the existing sampling methods are usually unavailable prior to any observations made in a practical environment.In this paper, a sequential sampling and estimation algorithm 5326058hx is proposed for approximately bandlimited graph sign
During Cluster spacecraft crossing of the magnetotail, a novel density depleted cavity in association with magnetic compressions in the outflow region of reconnection was observed.It contains intense reflected field-aligned particles, which are produced by a generation mechanism similar to that of the terrestrial foreshock, and hence manifests a fo
Abstract Transplantation of induced pluripotent stem cell-derived neural cells represents a promising strategy for treating neurodegenerative diseases.However, reprogramming of somatic cells and their subsequent neural differentiation is complex and time-consuming, thereby impeding autologous applications.Recently, direct transcription factor-based
Ischaemic left ventricular (LV) dysfunction can arise from myocardial stunning, hibernation, or necrosis.Imaging modalities have become front-line methods in the assessment of viable myocardial tissue, with the aim to stratify patients into optimal treatment pathways.Initial studies, although favorable, lacked sufficient power and sample size to pr
