Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Seasonal Variation in Dry Eye [PDF]

Ophthalmology, 2015
Dry eye (DE) is a common disease whose symptoms of pain (described as discomfort, burning, and dryness) and blurry vision negatively impact quality of life.1 We previously demonstrated that approximately 1 in 6 United States (US) veterans carried a diagnosis of DE and that environmental factors (air pollution coupled with weather conditions) affected ...

Seasonal, Diurnal and Wind-Direction-Dependent Variations of the Aerodynamic Roughness Length in Two Typical Forest Ecosystems of China

Terrestrial, Atmospheric and Oceanic Sciences, 2012
Aerodynamic roughness length (zom) is an important parameter for reliably simulating surface fluxes. The parameter varies with wind speed, atmospheric stratification, terrain and other factors; however, variations of this parameter are not properly ...

Autoimmune diseases and seasonal variations

Japanese Journal of Clinical Immunology, 2014
It has been reported that the exacerbation or development of autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis may have seasonality, although the seasonal characteristic depends on each disease. For example, the sunlight (ultraviolet) and infectious pathogens are involved in important environmental factors contributing ...
