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

, 1996 The timing-recovery subsystem of the receiver determines the sampling instants that are used for data detection. Since these instants are discrete, any phase-locked-loop (PLL) that is embedded in the timing-recovery subsystem has fundamentally a discrete-time nature.

A Novel Hybrid Control Approach for Frequency and Voltage Regulation in IPT Systems
IET Power ElectronicsThe purpose of the inductive power transfer (IPT) system is to deliver sufficient power from the power supply to the load via a magnetic coupler. To optimise the efficiency, transmission power, and stability of IPT systems, it is essential to sustain the

Mathematical models and simulations of phase noise in phase-locked loops [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2007 Phase noises in Phase-Locked Loops (PLLs) are a key parameter for communication systems that contribute the bit-rate-error of communication systems and cause synchronization problems.

IEEE Access, 2022 The conventional phase-locked loops or frequency-locked loops should take time to calibrate the oscillator’s resonant frequency in a super-regenerative receiver (SRR) and severely disrupts the receiver’s operations.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

A Single-Event-Hardened Scheme of Phase-Locked Loop Microsystems for Aerospace Applications
Micromachines, 2022 In order to improve the ability of the phase-locked loop (PLL) microsystem applied in the aerospace environment to suppress the irradiation effect, this study presents an efficient charge pump hardened scheme by using the radiation-hardened-by-design ...

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales
Advanced Engineering Materials, EarlyView.Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

Phase Locked Loop Test Methodology [PDF]
, 2008 Phase locked loops are incorporated into almost every large-scale mixed signal and digital system on chip (SOC). Various types of PLL architectures exist including fully analogue, fully digital, semi-digital, and software based.
