Clinical Course and Impact of Breaks in Therapy for Children With Relapsed/Refractory Solid Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pediatric relapsed or refractory (R/R) solid tumors carry a dismal prognosis, and postrelapse patient experiences are not well described. We present postrelapse outcomes, including number of R/R events and subsequent therapy regimens.

Design of Orthogonal Phase of Arrival Positioning Scheme Based on 5G PRS and Optimization of TOA Performance

IEEE Access
This study analyzes the performance of positioning techniques based on configuration changes of 5G New Radio (NR) signals. In 5G networks, a terminal’s position is determined from the Time of Arrival (TOA) of Positioning Reference Signals (PRS ...

Discriminator aided phase lock acquisition for suppressed carrier signals [PDF]

, 1982
A discriminator aided technique for acquisition of phase lock to a suppressed carrier signal utilizes a Costas loop which is initially operated open loop and control voltage for its VCXO is derived from a phase detector that compares the VCXO to a ...

Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

Improving the day-boundary discontinuities in BDS-3 carrier-phase time and frequency transfer

Geo-spatial Information Science
The BeiDou global satellite navigation system (BDS) is an important tool for precise remote time and frequency transfer. The current day-boundary discontinuity in the data process of the BDS-3 carrier phase (CP) time transfer limits the exploitation of ...

Phase Noise Modeling of Opto-Mechanical Oscillators [PDF]

, 2010
We build upon and derive a precise far from carrier phase noise model for radiation pressure driven opto-mechanical oscillators and show that calculations based on our model accurately match published phase noise data for such oscillators.
