  • Spin caloritronics of a quantum dot coupled to a magnetic insulator and normal metal

    Spin caloritronics of a quantum dot coupled to a magnetic insulator and normal metal

    This section is structured into several parts. First, we present the dispersion relation and the density of states (DOS) of the MI, followed by an analysis of how magnon interactions influence these quantities. Next, we discuss the results…

  • Low-dose, high-resolution CT of infant-sized lungs via propagation-based phase contrast

    Low-dose, high-resolution CT of infant-sized lungs via propagation-based phase contrast

    Experiments were performed at the Imaging and Medical Beamline (IMBL) of the Australian Synchrotron36 using the wiggler insertion device at 1.4 T. The sample was positioned approximately 137 m from the source, leading to an average…

  • Dual band bandpass filters with full band reflectionless response and enhanced upper stopband suppression

    Dual band bandpass filters with full band reflectionless response and enhanced upper stopband suppression

    The rapid evolution of modern wireless communication systems demands increasingly complex RF front-end solutions capable of supporting multi-band operations. Dual-band bandpass filters (BPFs) are essential components in these systems, enabling…

    Overview of the results

    We summarize the key contributions by informally stating the main results below. Let \({\mathcal{L}}({\boldsymbol{\theta }})\) be a loss function associated with a PQC described by a parameterized unitary U(θ), followed by…

    Unveiling interfacial dead layer in wurtzite ferroelectrics

    Ferroelectric ScAlN/GaN heterostructure

    As illustrated in Fig. 1a, a 70-nm-thick Sc0.18Al0.82N film was grown on 2-inch GaN/sapphire templates by MBE. The ScAlN film exhibited an atomically smooth surface and a single crystalline c-axis texture,…

  • Experimental results and analysis of plasma dynamics and radiation output of the 100 kV dense plasma focus FAETON-I

    Experimental results and analysis of plasma dynamics and radiation output of the 100 kV dense plasma focus FAETON-I

    1100 shots were fired on F-I to condition the device, ensure consistency in outputs, and establish optimal operating parameters. Throughout this conditioning, it was noted that the pressure ranges from 16 Torr to 12 Torr produced good focusing…

  • Deep reinforcement learning enhanced PID control for hydraulic servo systems in injection molding machines

    Deep reinforcement learning enhanced PID control for hydraulic servo systems in injection molding machines

    Joint simulation model environment

    This study employs a co-simulation framework integrating Simcenter AMESim and MATLAB/Simulink, with each platform serving distinct purposes: AMESim is responsible for modeling the servo-hydraulic system, while…
