Detent Force Suppression in DSPMLSM Using Magnetic Bridges With Windings
Permanent magnet linear synchronous motors (PMLSMs) are widely used in high‐precision servo systems. However, the detent force negatively affects servo performance.

Support structures are essential in additive manufacturing (AM) processes such as material extrusion, particularly for fabricating parts with overhanging features. However, conventional supports are typically removed after printing and cannot be reused, resulting in significant material waste and increased printing time.

Amyloid Forming Human Lysozyme Intermediates are Stabilized by Non‐Native Amide‐π Interactions
Mutational variants of human lysozyme cause fatal systemic amyloidosis by depositing kilograms of protein in the viscera of patients. Central to this process is a partially unfolded protein intermediate state that initiates aggregation into amyloid fibrils.
