Why Are All the Sets All the Sets?

open access: yesNoûs, 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.

Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

open access: yesNew 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 ...

QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Abstract Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation

Potential Flow Based Aerodynamic and Aeroelastic Analysis of flapping Wings

open access: yes, 2008
The motivation for this research is the importance that the modeling of aerodynamics and aeroelasticity of flapping wings has had in the last decade. The development of flapping wings Micro Air Vehicles (MAV) has captured a huge interest in the recent ...

Three‐dimensional digital quantitative analysis of periodontal and peri‐implant phenotype—A narrative review

open access: yesPeriodontology 2000, EarlyView.
Abstract 3D digital evaluation of the periodontal and peri‐implant tissue, including CBCT, intraoral scanning, optical surface scanning, and ultrasonography, is being used in the clinical arena with increasing frequency. Thus, to validate the utilization of 3D digital analysis for this purpose, a critical evaluation of the reliability of digital ...

Translational damping on high-frequency flapping wings

open access: yes, 2011
Flapping fliers such as insects and birds depend on passive translational and rotational damping to terminate quick maneuvers and to provide a source of partial stability in an otherwise unstable dynamic system.

Teaching Clinical Competency: Evaluating POCUS‐Guided Versus Landmark Techniques for Thoracostomy Tube Placement in Canine Cadavers by Veterinary Students

open access: yesJournal of Veterinary Emergency and Critical Care, EarlyView.
ABSTRACT Objective To evaluate the effectiveness of teaching novice learners the competency of small‐bore wire‐guided thoracostomy tube (SBWGTT) placement using point‐of‐care ultrasound (POCUS)‐guided and blind, landmark‐guided techniques and assess the complications associated with each technique. Design Crossover randomized study.

Classifying avian drinking behaviour: ecological insights and implications in a changing world

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1851-1862, August 2026.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns
