    Load‑bearing behaviors of sandwich plates with non‑uniformly distributed grid cores : Static compression and bending by Hao, Ning, Wang, Youlong, Song, Yiheng, Ruan, Sihan, Quanjin, Ma, Wang, Ziying

    Published 2023
    “…Under bending loading, most NUGPs experience local failure at the loading head, while the specific category surpassing GPs undergoes shear buckling in longer grid walls. (3) Deformation modes of the core layer, mechanical analysis, thin plate buckling theory, and equivalent bending stiffness calculations elucidate the load-bearing mechanisms of NUGPs. These findings enhance topology optimization research for sandwich plates, provide guidance for grid wall arrangements under different loading conditions, and offer insights for designing lightweight sandwich structures.…”

    Passive acoustic tracking of an unmanned underwater vehicle using bearing-Doppler-speed measurements by Kita, Kristen Railey, Randeni, Supun, DiBiaso, Dino, Schmidt, Henrik

    Published 2024
    “…The propeller rotation rate can be estimated from the motor signature and converted to speed using a pre-identified model of the robot. The bearing-Doppler-speed measurements outperformed traditional bearing-Doppler target motion analysis: the bearing, bearing rate, range, and range rate accuracy improved by a factor of 2×, 16×, 3×, and 6×, respectively. …”

    Synthesis and telomeric G-quadruplex-stabilizing ability of macrocyclic hexaoxazoles bearing three side chains by Ma, Yue, Iida, Keisuke, Sasaki, Shogo, Hirokawa, Takatsugu, Heddi, Brahim, Nagasawa, Kazuo, Phan, Anh Tuân

    Published 2019
    “…Here, we describe the synthesis of a new series of macrocyclic hexaoxazole-type G4 ligand (6OTD) bearing three side chains. One of these ligands, 5b, stabilizes telomeric G4 preferentially over the G4-forming DNA sequences of c-kit and K-ras, due to the interaction of its piperazinylalkyl side chain with the groove of telomeric G4.…”

    Numerical simulation and topology optimization of slider air bearing by Li, Qiang

    Published 2008
    “…Since the first commercial hard disk drive was developed in 1956, the stability of the flying attitude is always an important factor to be considered in the slider air bearing design. The objective of this dissertation is to develop an efficient computational modeling technique for simulating the air bearing slider (ABS) in hard disk drives and ultimately develop an effective topology optimization methodology to systematically and automatically design the air bearing slider with a target of achieving a near-constant flying attitude when the slider moves over the surface of the hard disk drive. …”
