Is the diatom sex clock a clock? [PDF]
Journal of The Royal Society Interface, 2021 The unique life cycle of diatoms with continuous decreasing and restoration of the cell size leads to periodic fluctuations in cell size distribution and has been regarded as a multi-annual clock. To understand the long-term behaviour of a population analytically, generic mathematical models are investigated algebraically and numerically for their ...

Archaeological clocks in the mosques of Vuh are an artistic archaeological study in light of agroup published for the first time [PDF]
Journal of Architecture, Art & Humanistic Science, 2022 The clock is a tool for knowing and measuring time، and the medieval Muslims، was in dire need to know the time and determine it، because the prayers imposed on them were linked to specific times of the day. Therefore، Muslim scholars at that time worked

Differential clock comparisons with a multiplexed optical lattice clock [PDF]
Nature, 2021 Rapid progress in optical atomic clock performance has advanced the frontiers of timekeeping, metrology and quantum science1–3. Despite considerable efforts, the instabilities of most optical clocks remain limited by the local oscillator rather than the ...

On the clock of the combinatorial clock auction [PDF]
Theoretical Economics, 2016 The combinatorial clock auction (CCA) has frequently been used in recent spectrum auctions. It combines a dynamic clock phase and a one‐off supplementary round. The winning allocation and the corresponding prices are determined by the Vickrey–Clarke–Groves rules.

Circadian Biology: Clocks within Clocks [PDF]
Current Biology, 2005 A small cluster of approximately 20,000 neurons in the ventral hypothalamus provide the body with key time-keeping signals and drive circadian rhythms. This circadian clock exhibits surprisingly complex substructures, with inputs from the retina, and outputs to other brain structures.

Nature Communications, 2022 Circadian rhythms are known to impact a range of biological processes including in the immune system. Here the authors show how circadian rhythms modulate the T cell response to vaccination via regulation of dendritic cell metabolism.

PLOS Biology, 2015 Circadian rhythms are an essential property of life on Earth. In mammals, these rhythms are coordinated by a small set of neurons, located in the suprachiasmatic nuclei (SCN). The environmental light/dark cycle synchronizes (entrains) the SCN via a distinct pathway, originating in a subset of photosensitive retinal ganglion cells (pRGCs) that utilize ...

Aging alters across-hemisphere cortical dynamics during binaural temporal processing
Frontiers in Neuroscience, 2023 Differences in the timing and intensity of sounds arriving at the two ears provide fundamental binaural cues that help us localize and segregate sounds in the environment. Neural encoding of these cues is commonly represented asymmetrically in the cortex
