    Process-Dependent Evolution of Channel Stress and Stress-Induced Mobility Gain in FinFET, Normal GAAFET, and Si/SiGe Hybrid Channel GAAFET by Chiang Zhu, Xiaona Zhu, Shaofeng Yu, David Wei Zhang

    Published 2025-01-01
    “…This study investigates the evolution of stress and its induced carrier mobility gain in FinFET, GAAFET, and Si/SiGe hybrid channel GAAFET throughout the process flow using technology computer-aided design (TCAD) tool, which has been calibrated with experimental data from the transmission electron microscopy (TEM) and nano-beam precession electron diffraction (PED) techniques. The stress evolution indicates that Fin recess, S/D epi growth and Gate removal are three crucial process steps that influence channel stress. …”

    Flexible and cost-effective deep learning for accelerated multi-parametric relaxometry using phase-cycled bSSFP by Florian Birk, Lucas Mahler, Julius Steiglechner, Qi Wang, Klaus Scheffler, Rahel Heule

    Published 2025-02-01
    “…In this study, feed-forward deep neural network (DNN)- and iterative fitting-based frameworks are compared for multi-parametric (MP) relaxometry based on phase-cycled balanced steady-state free precession (pc-bSSFP) imaging. The performance of supervised DNNs (SVNN), self-supervised physics-informed DNNs (PINN), and an iterative fitting framework termed motion-insensitive rapid configuration relaxometry (MIRACLE) was evaluated in silico and in vivo in brain tissue of healthy subjects, including Monte Carlo sampling to simulate noise. …”

    Particle motion and QPOs around Euler-Heisenberg black hole immersed in cold dark matter halo by G. Mustafa, S.K. Maurya, Tayyab Naseer, Arzu Cilli, Ertan Güdekli, Assmaa Abd-Elmonem, Neissrien Alhubieshi

    Published 2025-03-01
    “…The epicyclic oscillations of particles in proximity to stable circular orbits have been examined, and the phenomenon of periastron precession has been addressed. Additionally, we examine the collision of particles and the center of mass energy in proximity to the black hole's horizon. …”

    Detector development for spin-echo SANS techniques using ZnS:Ag/6LiF and 6Li glass scintillators by Giacomo Mauri, G. Jeff Sykora, Gregory N. Smith, Steven R. Parnell, Robert M. Dalgliesh, Dirk Honecker, Sarah E. Mann, Erik M. Schooneveld, Nigel J. Rhodes

    Published 2025-01-01
    “…Abstract Neutron spin-echo techniques exploit Larmor precession of the neutron spin to encode either the scattering angle or energy. …”

    Identifying a Point-Symmetrical Morphology in the Core-Collapse Supernova Remnant W44 by Noam Soker

    Published 2024-12-01
    “…I examine a radio map of W44 and find the outer bright rim of the radio map to possess a point-symmetric structure compatible with shaping by two energetic pairs of opposite jets rather than an S-shaped morphology shaped by a precessing pair of jets. An inner pair of filaments might hint at a third powerful pair of jets. …”

    Optimum Tuning of a Gyroscopic Vibration Absorber Using Coupled Gyroscopes for Vibration Control of a Vertical Cantilever Beam by F. Ünker, O. Çuvalcı

    Published 2016-01-01
    “…These coupled gyroscopes use two gyroscopic flywheels, spinning in opposing directions to have reverse precessions to eliminate the forces due to the torque existing in the torsional spring and the damper between gyroscopes. …”

    Influences of Dual Air-Swirler Angles on Swirling Injection and Combustion of Kerosene-Air at a Supercritical Pressure by Danyang Wang, Danyang Wang, Dongxin Huang, Jianguo Xu, Hua Meng, Hua Meng

    Published 2025-01-01
    “…Numerical results indicate that the inner air swirler exerts strong impact on fuel-air mixing and chemical reactions inside the inner injector, leading to a Y shaped recirculating flow and a V shaped flame at an inner swirler angle of 40°. The precessing vortex core (PVC) is generated by the inner air swirling injection, and detailed analyses reveal that the PVC frequency is controlled mainly by the inner swirl number and the maximum axial velocity from the inner injector. …”
