A Low-Complexity Time-Domain Method for a Fast and Accurate Measurement of Q-Factor and Resonant Frequency of RF and Microwave Resonators

open access: yesIEEE Access, 2021
A new time-domain technique for an accurate and fast measurement of the resonant frequency and $Q$ -factor of resonators is presented. In this technique, the phase slope with respect to frequency of a resonator is characterized and used to specify its $

Evidence for Multiple Shocks from the γ-Ray Emission of RS Ophiuchi

open access: yesThe Astrophysical Journal, 2023
In 2021 August, the Fermi Large Area Telescope, H.E.S.S., and MAGIC detected GeV and TeV γ -ray emission from an outburst of recurrent nova RS Ophiuchi. This detection represents the first very high-energy γ -rays observed from a nova, and it opens a new

A time domain anti-jamming processing algorithm for GNSS ranging receiver

open access: yesFrontiers in Physics, 2022
Traditional anti-jamming algorithms lead to a deviation of the Global Navigation Satellite System receiver’s ranging value, which has become the main obstacle to the improvement of the accuracy of the high-precision ranging receiver.

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

PSR J1947−1120: A New Huntsman Millisecond Pulsar Binary

open access: yesThe Astrophysical Journal
We present the discovery of PSR J1947–1120, a new huntsman millisecond pulsar with a red giant companion star in a 10.3 day orbit. This pulsar was found via optical, X-ray, and radio follow-up of the previously unassociated γ -ray source 4FGL J1947.6 ...

Time-domain studies of M31 [PDF]

open access: yesAstronomical Review, 2016
M31, our closest neighboring galaxy, is a stepping stone to studies of stellar evolution, star formation, galaxy evolution, and cosmology. However, due to the difficulties of performing photometry in such crowded fields and the lack of wide cameras to encompass the entire galaxy, there has not been a complete census of the stellar contents of M31.
