Dissecting the SMC

open access: yes, 2019
One of the key puzzles in modern astrophysics is to understand how galaxies form and evolve. In particular, interactions are important drivers of galaxy formation and evolution. Hence, studying these encounters within our Local Group systems, where we can resolve individual stars, can help us understand these processes.

Digital Twins for the Design, Interactive Control, and Deployment of Modular, Fiber‐Reinforced Soft Continuum Arms

open access: yesAdvanced Intelligent Systems, EarlyView.
A digital twin framework is presented for modular soft continuum arms built from fiber‐reinforced pneumatic actuators. Cosserat rod models describe individual actuators, while virtual assemblies are formed through serial and parallel networks, preserving actuator‐level architecture and arm deformation.

Natural Aging of Biomaterials in Ambient and Physiological Environments

open access: yesAdvanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

The Zhang Knot: A Locking Slip‐Knot for Arthroscopy

open access: yesArthroscopy Techniques, EarlyView.
Abstract The Zhang knot is a sliding knot for arthroscopic surgery that is simple to learn, easy to slide, and can be securely locked. This technique, which is similar to a reverse Tennessee knot, is described in detail with step‐by‐step illustrations and a video demonstration.

Exploring individualized crovalimab dosing in PNH through in silico modelling: Potential for improved convenience and cost efficiency

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Paroxysmal nocturnal haemoglobinuria (PNH) is a rare, acquired haematopoietic stem cell disorder. Crovalimab, a complement C5‐inhibitor, is approved for PNH and can be self‐administered subcutaneously every 4 weeks, offering a more convenient route than intravenous C5‐inhibitors.
