Time Restricted Feeding to the Light Cycle Dissociates Canonical Circadian Clocks and Physiological Rhythms in Heart Rate [PDF]
Frontiers in Pharmacology, 2022 Circadian rhythms are approximate 24-h biological cycles that optimize molecular and physiological functions to predictable daily environmental changes in order to maintain internal and organismal homeostasis.

Activation of the PACAP/PAC1 Signaling Pathway Accelerates the Repair of Impaired Spatial Memory Caused by an Ultradian Light Cycle [PDF]
ASN Neuro, 2023 The mechanism of light-induced spatial memory deficits, as well as whether rhythmic expression of the pituitary adenylyl cyclase-activating polypeptides (PACAP)-PAC1 pathway influenced by light is related to this process, remains unclear.

Lighting for cycling in the UK—A review [PDF]
Lighting Research & Technology, 2015 While UK governments have recently sought to increase cycling activity, it remains a minority interest. One reason for this is the perceived danger of cycling on roads filled with traffic. There is statistical evidence to support this perception; for equal exposure, cyclists are more likely to be seriously injured than either drivers or pedestrians ...

The Annual Cycling of Nighttime Lights in India [PDF]
Remote Sensing, 2021 India is known to have unstable power supply, and many locations show an annual cycle in VIIRS Nighttime Light (VNL). In this study, autocorrelation function (ACF) analysis is used to identify the annual cycling in VNL. Two fundamentally different classification techniques are proposed to classify the ACF profile into one of the three arch types, i.e.,
