Lift enhancement by dynamically changing wingspan in forward flapping flight
, 2014 Dynamically stretching and retracting wingspan has been widely observed in the flight of birds and bats, and its effects on the aerodynamic performance particularly lift generation are intriguing.

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds
Journal of Anatomy, EarlyView.The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Journal of Prosthodontics, EarlyView.Abstract Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri‐implant health, and ensure long‐term success. Traditionally, titanium stock healing abutments or chairside‐customized abutments were used to shape peri‐implant tissues and develop the emergence profile for implant‐supported prostheses.

Journal of Prosthodontics, EarlyView.Abstract This clinical report presents a comprehensive digital workflow for rehabilitating a patient with maxillary terminal dentition using a full‐arch, implant‐supported fixed dental prosthesis (FP‐1). It highlights the integration of a 3D‐printed polychromatic flangeless trial denture and a customized anatomic bone reduction template, enabling ...

Contrasting mechanisms driving the northward expansion of African raptors in Europe
Journal of Zoology, EarlyView.Recent climate warming and landscape changes are enabling African raptors to reach Europe through contrasting mechanisms. Using species distribution models, we show that the Atlas Long‐legged Buzzard expands northward following climatic suitability, whereas African vultures reach Europe despite low climatic favourability through socially mediated ...

Why Are All the Sets All the Sets?
Noûs, EarlyView.ABSTRACT Necessitists about set theory think that the pure sets exists, and are the way they are, as a matter of necessity. They cannot explain why the sets (de rebus) are all the sets. This constitutes the Ur‐Objection against necessitism; it is the primary motivation cited by potentialists about set theory.

New Phytologist, EarlyView.Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...
