Vortex-Induced Motions of Floating Offshore Wind Turbine Structures
The ‘Green Shift’ from fossil energy (coal, oil and natural gas) to renewable energy (sunlight, wind, waves and tide) is now a global trend. DNV forecasts that by 2050, the installed floating global wind capacity will have grown from today’s 100 megawatts (MW) to over 264 gigawatts (GW), so that 2% of the world’s electricity demand can be supplied by cost-efficient and dependable floating offshore wind. Floating offshore wind is considered to be a viable solution at water depths exceeding 50 to 60 m with abundant wind resources. As a fast-evolving technology, it has the potential for less foundation material, shortened installation cycle and decommissioning, and additional wind power generation.

Vortex Pinning Centers in High-Temperature Superconducting Films
To better pin the vortex at external magnetic fields, the HTS films must contain APCs with desired morphology, dimension, orientation, and concentration. Nanoscale APCs with lateral dimension approaching 2ξ (coherence length) on the order of a few nanometers in HTSs must be generated to suppress the dissipation of vortex motion. This has prompted extensive efforts and exciting results have been obtained in generating nanoscale APCs in HTS films. The research progress of different types and dimensions APCs in detail is introduced and the impact on superconducting performance is summarized.

Von Willebrand Factor, ADAMTS13 and Cardiac Disease
This entry briefly describes the involvement of VWF (von Willebrand factor) and ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin type 1 motif-13) in the pathophysiology of cardiac disease.

Von Willebrand Factor
The von Willebrand factor (vWF) is a plasma protein that mediates platelet adhesion and leukocyte recruitment to vascular injury sites and carries coagulation factor VIII, a building block of the intrinsic pathway of coagulation. A steep rise in shear rates, which may occur at sites of arterial stenosis and injury, is crucial for unfolding and activation of vWF. The hemostatic activity of vWF is counterbalanced by ADAMTS-13, a vWF-cleaving protease. The presence of ultra-large multimers of vWF in the bloodstream is associated with spontaneous thrombosis, whereas its deficiency leads to bleeding.

Von Hippel-Lindau Syndrome
Von Hippel-Lindau syndrome is an inherited disorder characterized by the formation of tumors and fluid-filled sacs (cysts) in many different parts of the body. Tumors may be either noncancerous or cancerous and most frequently appear during young adulthood; however, the signs and symptoms of von Hippel-Lindau syndrome can occur throughout life.

Volvocine regA Gene Model for Cellular Differentiation Evolution
A group of green algae in the order of Volvocales provides an ideal model system for studying the transition from unicellular to differentiated multicellularity. This group—known as the volvocine algae—evolved multicellularity relatively recently (~240 million years ago) and contains extant relatives that span a range of complexities from unicellularity, to undifferentiated multicellularity, to differentiated multicellularity. The regA-like gene family within the volvocine algae serves as a model for the evolution of the genetic basis of cellular differentiation.

Volunteers Nature Conservation Motivational Factors
Global biodiversity is under pressure from human activities, and the effort for nature conservation and restoration and the allocation of economic resources for biodiversity policies remain insufficient. In such a context, volunteers can play an important role as a resource in nature conservation projects if their recreational activities interact with the objectives of nature management. Ensuring that volunteers remain motivated and engaged is crucial for the success of conservation projects. Five motivational factors determine the engagement of the volunteers, namely social, nature value, instrumental, identification, and personal benefit.
