Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

open access: yesThe Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Three-dimensional higher-order saddle-point-induced flatbands in Co-based kagome metals

open access: yesPhysical Review Research
The saddle point (Van Hove singularity) exhibits a divergent density of states in two-dimensional systems, leading to fascinating phenomena such as strong correlations and unconventional superconductivity, yet it is seldom observed in three-dimensional ...

Solid State Self‐Assembly of an Extended Curved‐Arm Nickel(II) Macrocycle with Fullerene C60

open access: yesChemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.
Three co‐crystalline structures that contain fullerene C60 and (5,14‐dihydro‐6,8,15,17‐tetrabenzyl‐2,3,11,12‐tetramethyldibenzo[b,i][1,4,8,11]tetraazacyclotetradecine)nickel(II) show the formation discrete one‐dimensional hollow channels as a results of 1 : 1 interplay and 1 : 2 dimeric interplay with the fullerenes arranged in hexagonal arrays ...

A Romantic Genius? The Experience of Knowledge that Shaped Werner Heisenberg's Scientific Persona

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
In 1976, the year that Werner Heisenberg passed away, Armin Hermann published a short biography, titled Werner Heisenberg in Selbstzeugnissen und Bilddokumenten. Since then, historians and biographers have offered their accounts on Heisenberg's life and his contributions to modern physics. Many of these biographies present Heisenberg as a genius.

Morphology of the sternoclavicular joint and its microanatomical changes in response to osteoarthritic degeneration

open access: yesClinical Anatomy, EarlyView.
Abstract Although the sternoclavicular joint shares structural similarities with the knee and hip joints as a diarthrodial joint, its biomechanics differ significantly due to its non‐weight‐bearing nature. Nevertheless, it is subject to considerable loading, leading to increased susceptibility to osteoarthritis, a prevalent condition characterized by ...
