Optical SSB modulator/frequency shifter with ultralow spurious sidebands.
Safavi N, Esmail Hosseini S. Safavi N, et al. Appl Opt. 2020 Aug 20;59(24):7408-7418. doi: 10.1364/AO.396844. Appl Opt. 2020. PMID: 32902509
In this paper, we report and theoretically investigate an optical single-sideband suppressed-carrier (OSSB-SC) modulator/frequency shifter with ultralow spurious sidebands. The novel, to the best of our knowledge, structure is based on three Sagnac interferometers ( …

Spurious cross-frequency amplitude-amplitude coupling in nonstationary, nonlinear signals.
Yeh CH, Lo MT, Hu K. Yeh CH, et al. Physica A. 2016 Jul 15;454:143-150. doi: 10.1016/j.physa.2016.02.012. Physica A. 2016. PMID: 27103757 Free PMC article.
Recent studies of brain activities show that cross-frequency coupling (CFC) play an important role in memory and learning. Many measures have been proposed to investigate the CFC phenomenon, including the correlation between the amplitude envelopes of two brain waves at di …

Modeling for High-Frequency Spurious Responses in Incredible High-Performance Surface Acoustic Wave Devices.
Jiang G, Shuai Y, Wei Z, Yao J, Luo W, Pan X, Wu C, Zhang W. Jiang G, et al. Micromachines (Basel). 2024 Jan 15;15(1):134. doi: 10.3390/mi15010134. Micromachines (Basel). 2024. PMID: 38258253 Free PMC article.
To ensure that surface acoustic wave (SAW) filters fulfill the requirements of Carrier Aggregation (CA) applications, the development of modeling tools that can forecast and simulate high-frequency spurious responses has been necessary. This paper presents an advanc …

Confounding.
van Stralen KJ, Dekker FW, Zoccali C, Jager KJ. van Stralen KJ, et al. Nephron Clin Pract. 2010;116(2):c143-7. doi: 10.1159/000315883. Epub 2010 Jun 1. Nephron Clin Pract. 2010. PMID: 20516714 Free article. Review.
If one incorrectly adjusts for a variable that is not a confounder, one risks overadjustment or adjustment for spurious associations. Confounders can be prevented from entering the study, during the design of a study, or if this is not possible, one can try to remove it du …

Spurious phase correction in rapid metabolic imaging.
El Sabbagh N, Chassain C, Ratiney H, Pagés G, Bonny JM. El Sabbagh N, et al. J Magn Reson. 2021 Nov;332:107065. doi: 10.1016/j.jmr.2021.107065. Epub 2021 Sep 8. J Magn Reson. 2021. PMID: 34560390
It is critical that the phase variation during the evolution time for each scan is only dependent on chemical shifts. In this paper, we described the apparition of spurious phase due to either the transmit or the receive frequency. The presence of this unwanted phas …
