Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

BER analysis of hybrid carrier system based on WFRFT with carrier frequency offset
Electronics Letters, 2015 Carrier frequency offset (CFO) due to Doppler shift or misaligned frequency between the transmitter and the receiver has a serious impact on both orthogonal frequency division multiplexing (OFDM) and single carrier (SC) communication systems. Inter‐carrier interference coefficients of OFDM system produced by CFO have been proposed and applied in ...
