Turbidity-adaptive underwater image enhancement method using image fusion

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 3, doi: 10.1007/s11465-021-0669-8

Abstract: Clear, correct imaging is a prerequisite for underwater operations.Most of the existing underwater imaging methods focus on relatively clear underwater environment, itis uncertain that if those methods can work well in turbid and dynamic underwater environments.In this paper, we propose a turbidity-adaptive underwater image enhancement method.The proposed method is verified by an underwater image dataset captured in real underwater environment

Brown and beige fat: the metabolic function, induction, and therapeutic potential

Shuwen Qian,Haiyan Huang,Qiqun Tang

Frontiers of Medicine 2015, Volume 9, Issue 2,   Pages 162-172 doi: 10.1007/s11684-015-0382-2

Abstract:

Adipose tissue is an important organ for energy homeostasis. White adipose tissue stores energy in the form of triglycerides, whereas brown adipocytes and recently identified beige adipocytes are specialized in dissipating energy by thermogenesis or contribution to dispose glucose and clear triglycerides in blood. The inverse correlation between the brown adipose tissue activity and body mass suggests its protective role against body fat accumulation. Thus, recruitment and activation of brown or beige adipose tissue become particularly appealing targets for increasing energy expenditure. Angiogenesis and sympathetic nerve signals are the fundamental determinants for brown and beige adipose tissue development, as well as for their metabolic functions. Secretary factors including BMPs can induce the development, the activation of brown or beige adipose tissue, which seem to be promising for therapeutic development.
