Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

Advanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

The motion of a rotor carried by a flexible shaft in flexible bearings [PDF]

Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1933
Abstract 1.1.—Scope of Investigation.—This paper discusses the transverse motion of a rotor carried by a flexible shaft rotating in flexibly-supported bearings. The rotor is assumed to consist of one or more rigid bodied mounted on a shaft which is weightless and torsionally rigid.

Responsive Membrane Antenna Enables Adaptive Biohybrid Interface for Photosynthesis Promotion, Stress Reporting and Modulation

Advanced Science, EarlyView.
An environmentally responsive antenna assembled onto the algal cell membrane creates a biohybrid with a responsive interface that promotes photosynthesis under normal conditions and shifts to H2O2‐triggered stress reporting and modulation upon stress onset, boosting environmental sensing and adaptive response.

Active Control for Whirling Motion of Flexible Rotor

Journal of Robotics and Mechatronics, 1991
In a rotational machine, unbalance on the rotor is formidable since it causes resonance synchronized with the rotation of the rotor. In order to suppress this unfavorable vibration, we built an active vibration control system of flexible rotor using an electromagnetic damper.
