Influence of equipment excitation on flexible carbody vibration of EMU [PDF]

open access: yesJournal of Modern Transportation, 2014
To study the vibration transmission characteristics of a flexible carbody and its suspended equipment, a vertical mathematical model of high-speed electric multiple unit was established with equipment excitation considered. And the dynamic unbalance and impact turbulence excitation from equipment were taken into account in a single-stage and two-stage ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Dynamic response analysis of solitary flexible rocking bodies: modeling and behavior under pulse-like ground excitation

open access: yes, 2014
Results obtained for rigid structures suggest that rocking can be used as seismic response modification strategy. However, actual structures are not rigid: structural elements where rocking is expected to occur are often slender and flexible. Modeling of
