This brief article is an introduction to the feature article on self-reflection in interpretive phenomenology research. Self-reflection is discussed as a method that warrants more explicit description in the practice of qualitative research. Research does not occur in an epistemic vacuum. Despite researchers' entanglement in the process of research and the fuzziness of the phenomenon under study, scientific methods, including that of self-reflection, enable nurse scientists to persevere in their study of human health experiences.

Preparation, articulation, and photogrammetry of a neonatal moose skeleton.

Department of Ecosystem Science and Management, University of Northern British Columbia, 3333 University Way, Prince George, British Columbia V2N 4Z9 (McVea, Richter, Rea); Applied Technology Group, TRIUMF, 4004 Wesbrook Mall, Vancouver, British Columbia V6T 2A3 (McLatchy).
Objective: Neonatal skeletal articulations for research and display purposes are uncommon due to issues surrounding incomplete bone maturation and reduced structural integrity that affect the bone preparation and articulation procedures. The present project was designed to add to the veterinary literature on neonatal moose osteological specimens, document the procedures of preparing and articulating a delicate specimen, and construct a 3-dimensional (3D) scan of the articulated skeleton that could be used for scientific and veterinary research and study worldwide.
Animal: A neonatal moose that had succumbed to capture myopathy resulting from entanglement in a barbed wire fence was the sole subject of this project.

Form-function relationships often have tradeoffs: if a material is tough, it is often inflexible, and vice versa. This is particularly relevant for the elephant trunk, where the skin should be protective yet elastic. To investigate how this is achieved, we used classical histochemical staining and second harmonic generation microscopy to describe the morphology and composition of elephant trunk skin.

Measuring bipartite fluctuations of a conserved charge, such as the particle number, is a powerful approach to understanding quantum systems. When the measured region has sharp corners, the bipartite fluctuation receives an additional contribution known to exhibit a universal angle dependence in 2D isotropic and uniform systems. Here we establish that, for generic lattice systems of interacting particles, the corner charge fluctuation is directly related to quantum geometry.

Classification and regression problems can be challenging when the relevant input features are diluted in noisy datasets, in particular when the sample size is limited. Traditional Feature Selection (FS) methods address this issue by relying on some assumptions such as the linear or additive relationship between features. Recently, a proliferation of Deep Learning (DL) models has emerged to tackle both FS and prediction at the same time, allowing non-linear modeling of the selected features.

Biomacromolecular networks with multiscale fibrillar structures are characterized by exceptional mechanical properties, making them attractive architectures for synthetic materials. However, there is a dearth of synthetic polymeric building blocks capable of forming similarly structured networks. Bottlebrush polymers (BBPs) are anisotropic graft polymers with the potential to mimic and replace biomacromolecules such as tropocollagen for the fabrication of synthetic fibrillar networks; however, a longstanding limitation of BBPs has been the lack of rigidity necessary to access the lyotropic ordering that underpins the formation of collagenous networks.
