Explores for the source of the gears in traditional Japanese clock (Wadokei)
Nihon Kikai Gakkai ronbunshu, 2017 The purpose of this study is to understand the nature of one of the oldest gears used in traditional Japanese clock. Today's gear manufacturing technology in Japan came mostly from Europe and America, but we do not know exactly, when and how the ...

Circadian Control of Inflammasome Pathways: Implications for Circadian Medicine
Frontiers in Immunology, 2020 The innate immune system senses “non-self” molecules derived from pathogens (PAMPs) as well as endogenous damage-associated molecular patterns (DAMPs) and promotes sterile inflammation that is necessary for injury resolution, tissue repair/regeneration ...

Electronic system for drift clock calculation and synchronization for seafloor observatory [PDF]
, 2016 The paper describes a new electronic device that allows an easily measurement of the drift between a reference time source (usually GPS) and an atomic rubidium clock which is normally used in seafloor observatories.

The thermodynamics of clocks [PDF]
Contemporary Physics, 2020 All clocks, classical or quantum, are open non equilibrium irreversible systems subject to the constraints of thermodynamics. Using examples I show that these constraints necessarily limit the performance of clocks and that good clocks require large energy dissipation.

Regulation of amyloid-β dynamics and pathology by the circadian clock
Journal of Experimental Medicine, 2018 Nighttime restlessness and daytime drowsiness are common and early symptoms of Alzheimer’s Disease (AD). This symptomology implicates dysfunctional biological timing, yet the role of the circadian system in AD pathogenesis is unknown.

mTOR signaling regulates central and peripheral circadian clock function
PLoS Genetics, 2018 The circadian clock coordinates physiology and metabolism. mTOR (mammalian/mechanistic target of rapamycin) is a major intracellular sensor that integrates nutrient and energy status to regulate protein synthesis, metabolism, and cell growth.

Realisation of High-Frequency DRO Oscillators with Mosfet Transistors for Sub-MMWAVE Band
Acta Electrotechnica et InformaticaIn high-frequency electronics, optimizing RF oscillators performance is essential, especially as applications reach into wide frequency bands. This article describes proposed clock generators for UWB sensor systems based on oscillators with dielectric ...

The Genomics of Circadian Timing in a Wild Bird, the Great Tit (Parus major)
Frontiers in Ecology and Evolution, 2019 Circadian rhythms are ubiquitous among taxa and are essential for coping with recurrent daily events, leading to selection on the properties of the clock underlying these rhythms.

Synchronization tracking in pulse position modulation receiver [PDF]
, 1987 A clock pulse generator for decoding pulse position modulation in an optical communication receiver is synchronized by a delay tracking loop which multiplies impulses of a data pulse by the square wave clock pulses from the generator to produce positive ...
