Aging Fly Cell Atlas identifies exhaustive aging features at cellular resolution
Aging is characterized by a decline in tissue function, but the underlying changes at cellular resolution across the organism remain unclear. Here, we present the Aging Fly Cell Atlas, a single-nucleus transcriptomic map of the whole aging Drosophila. We c ...
AMER ASSOC ADVANCEMENT SCIENCE2023DASS: Combining Dynamic & Static Scheduling in High-Level Synthesis
A central task in high-level synthesis is scheduling: the allocation of operations to clock cycles. The classic approach to scheduling is static, in which each operation is mapped to a clock cycle at compile-time, but recent years have seen the emergence o ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Rocker oscillator time bases
Simon Nessim Henein, Ilan Vardi
Since the invention of the pendulum clock by Christiaan Huygens in 1657, precision timekeepers have been regulated by oscillators. Although the pendulum is not an isochronous oscillator, its introduction as a time basis for clock regulation led to a signif ...
2021Shaking force balancing of a 2-DOF isotropic horological oscillator
Simon Nessim Henein, Hubert Pierre-Marie Benoît Schneegans, Etienne Frédéric Gabriel Thalmann
Despite centuries of research and significant advances, the escapement mechanism used to count and maintain oscillations of mechanical time bases remains a complex mechanism and a major source of energy losses. We showed in previous work that, instead of t ...
2021Optical measurement method for mechanical time base characterization
Simon Nessim Henein, Etienne Frédéric Gabriel Thalmann
The recent adoption of silicon components by the mechanical watch industry has triggered the search for new time bases to advantageously replace the traditional balance and hairspring oscillator. In particular, flexure-based oscillators manufactured in sil ...
2021Human circadian rhythms and urban density: celebrating the natural day-night cycle
Marilyne Andersen, Mark Pauly, Florin Isvoranu, Megan Nicole Danell, Javier Fernandez Contreras
Our exposure to light has a key role in regulating our biological clock through a dedicated photoreceptor present in the human eye. Increased awareness to its criticality when it comes to human well-being is urgently needed, as this criticality is potentia ...
SoomeenHahm Design Ltd2021Flexure Pivot Oscillators for Mechanical Watches
Etienne Frédéric Gabriel Thalmann
It appears that the concerted efforts of the watchmaking industry are leading towards a limit in mechanical watch accuracy. The general consensus in horology is that the time base's quality factor, a dimensionless number that characterizes the oscillator d ...
