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 $

Neuropsychological and Educational Outcomes in Shwachman–Diamond Syndrome—A Report From the North American Shwachman–Diamond Syndrome Registry

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Shwachman–Diamond syndrome (SDS) is a rare autosomal recessive ribosomopathy characterized by bone marrow failure and multisystem involvement, with emerging evidence of associated neurocognitive impairment. Methods We conducted a retrospective study of 240 individuals with biallelic Shwachman–Bodian–Diamond syndrome (SBDS) mutations

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.

Electromagnetic forces in the time domain

open access: yesOptics Express, 2022
We look beyond the standard time-average approach and investigate optical forces in the time domain. The formalism is developed for both the Abraham and Minkowski momenta, which appear to converge in the time domain. We unveil an extremely rich – and by far unexplored – physics associated with the dynamics of the optical forces, which can even attain ...

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Time Domain Infinite Impulse Response Filtering Approach for Simulation of Pulse Propagation in Optical Fiber with PMD [PDF]

open access: yes, 2005
In this thesis, we have developed a full time domain approach for the simulation of pulse propagation in the optical fiber. Same as split-step method in frequency domain, this approach also treats the linear and nonlinear process alternately.
