Voice and Speech in Atypical Parkinsonian Disorders
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

The fundamental question of how to assign NMR resonances to specific atoms in the unit cell is addressed by using the 9Be and 11B spectra of the natural mineral hambergite as a model system. ABSTRACT The NMR interaction tensors of 9Be and 11B of hambergite, Be2$$ {}_2 $$BO3$$ {}_3 $$OH, were derived from single‐crystal NMR experiments.

A Peridynamic Framework for Modeling Progressive Failure in Porous Sandstone Indentation
ABSTRACT A state‐based peridynamic model is proposed to simulate the failure mechanisms in porous rocks, using Bentheim sandstone as a specific example. Experimental observations reveal a transition from brittle to ductile failure under increasing triaxial compression. This behavior is attributed to pore compaction. The peridynamic model is enhanced to
