Characterisation of human hair follicle development
Journal of Anatomy, EarlyView.Schematic of hair follicle development in human skin. Hair follicle primordia of similar sizes, but different densities, are laid out across the skin. The distinction between terminal and vellus hair sites is not obvious at early stages of hair follicle development.

Application Value of Slider-Crank Mechanism in Pick-and-Place Operation of Delta Robot
MATEC Web of Conferences, 2018 By absorbing the advantages of the rotary-driven Delta robot and linear-driven Delta robot, a Delta robot for pick-and-place operation that forms a crank-slider at the drive joint is designed.To take the most common gate shaped curve in Cartesian space ...

Ecology and Evolution, Volume 16, Issue 7, July 2026.This study tested physiological mechanisms of movement patterns in Gopher Tortoises (Gopherus polyphemus) by using autonomous GPS loggers. Total distance traveled, but not home range area, was physiologically limited. Females traveled the same distance as males, but had smaller home range areas, which challenges traditional understanding of sex‐based ...

Synthesis of Spatial Slider-Crank Mechanism for High-Speed Applications
, 2020 Certain kinematic design constraints can be derived based on requisite dynamic performance requirements of a mechanism. Perhaps a most suitable kinematic synthesis task related to dynamic performance is function generation involving the entire motion ...

Journal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.ABSTRACT Research on anaerobic ciliates has intensified over the past decades, with Armophorea being most studied, but members of Armophorida remaining relatively understudied. Previously, the genus Sulfonecta Jankowski, 1978 was monotypic, with S. uniserialis (Levander, 1894) Jankowski, 1978 as the type species.

Delamination of Vermiculite into Ultrahigh‐Aspect‐Ratio Nanosheets
Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.Efficient ion exchange allows for thermodynamically driven delamination of vermiculite into high‐aspect ratio nanosheets. The applicability of sustainable materials in the packaging industry is currently limited by the poor gas barrier performance of most biodegradable polymers.
