IET Generation, Transmission & Distribution, 2023 This paper proposes a new robust method for accurately and reliably estimating remote bus frequencies in a power system. Two different measurement sources for the remote bus frequency are considered, that is, the ideal Frequency Divider (FD) and the ...

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

An improved second order generalized integrators phase locked loop for flexible DC transmission
Energy Reports, 2022 Accurate and fast phase locking is the primary condition for flexible DC transmission to realize reliable control. When the power grid is unbalanced or contains high-order harmonics, the traditional second order generalized integrator (SOGI) itself has ...

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Fractional-N PLL based FMCW sweep generator for an 80 GHz radar system with 24.5 GHz bandwidth [PDF]
Advances in Radio Science, 2012 A phase-locked loop (PLL) based frequency synthesizer capable of generating highly linear broadband frequency sweeps as signal source of a high resolution 80 GHz FMCW radar system is presented. The system achieves a wide output range of 24.5 GHz starting

FEBS Open Bio, EarlyView.We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

High Dynamic Optimized Carrier Loop Improvement for Tracking Doppler Rates
Journal of Electrical and Computer Engineering, 2015 Mathematical analysis and optimization of a carrier tracking loop are presented. Due to fast changing of the carrier frequency in some satellite systems, such as Low Earth Orbit (LEO) or Global Positioning System (GPS), or some planes like Unmanned ...
