Max Willsey, Chandrakana Nandi, Yisu Remy Wang, Oliver Flatt, Zachary Tatlock, Pavel Panchekha
2020 arXiv   pre-print
This work contributes two techniques that make e-graphs fast and extensible, specializing them to equality saturation.  ...  Equality saturation workloads exhibit distinct characteristics and often require ad-hoc e-graph extensions to incorporate transformations beyond purely syntactic rewrites.  ...  1813166 and 1749570.  ...

Exchange of monooleoylphosphatidylcholine with single egg phosphatidylcholine vesicle membranes

D.V. Zhelev
1996 Biophysical Journal  
In a previous paper we described the experiments and the framework of a model for the exchange of monooleoylphosphatidylcholine with a single egg phosphatidylcholine membrane.  ...  This relative extension of one of the monolayers induces a monolayer tension.  ...  This molar concentration of MOPC sets the limit for using the presented model for the case of fast saturation.  ...

Eggs were recovered from the flotation solution and concentrated by sieving. Lysis was achieved by repeated boiling and freezing cycles -only Trichuris eggs required additional mechanic disruption.  ...  A direct PCR from crude egg preparations was designed for full compatibility with FLOTAC to accurately quantify eggs per gram feces (epg) and determine species composition.  ...  Acknowledgments The authors would like to thank Frank Mockenhaupt (Charité, Berlin) for giving access to fecal samples, Claudia Welz (Bayer Animal Health) for providing Trichuris positive samples and Hans-Peter  ...

The Evolution of Alternative Buoyancy Mechanisms in Freshwater Fish Eggs

Feng Chen, Carl Smith, Yeke Wang, Jun He, Wulai Xia, Ge Xue, Jun Chen, Ping Xie
2021 Frontiers in Ecology and Evolution  
We applied a physical model of buoyancy to understand the contributions of oil droplets and hydration to the buoyancy of pelagic freshwater fish eggs.  ...  ARTs are widespread in nature, and are a particular feature of teleost fishes. However, few studies have examined egg buoyancy mechanisms in the context of the evolution of ARTs in freshwater fishes.  ...  As the force patterns of fish eggs are concordant in seawater and freshwater, egg buoyancy is equal to the difference between the densities of water current and the egg when the pelagic egg remains in  ...

Oscillatory regimes in a mosquito population model with larval feedback on egg hatching [article]

Martin Strugarek, Nicolas Vauchelet, Benoît Perthame (LJLL, MAMBA), Daniel Villela
2018 arXiv   pre-print
We propose both a theoretical analysis, based on slow-fast dynamics and Hopf bifurcation, and numerical investigations in order to shed some light on the mechanisms at work in this model.  ...  We propose a simple mathematical model of egg hatching enhancement by larvae which produces such oscillations that conveys a possible explanation.  ...  Firstly (Section 3) when the quantity of eggs is large compared to the quantity of larvae, oscillations can appear and we are faced to a slow-fast oscillatory regime giving rise to oscillation profiles  ...

Voltage clamp analysis of two inward current mechanisms in the egg cell membrane of a starfish

S. Hagiwara
1975 The Journal of General Physiology  
The relationship between the membrane current and the concentration of the permeant ions is also different between the two channels. The result suggests that channel II is a more saturable system.  ...  Ionic mechanisms of excitation were studied in the immature egg cell membrane of a starfish, Mediaster aequalis, by analyzing membrane currents during voltage clamp.  ...  The authors wish to thank Professors Charles Edwards and Alan D. Grinnell for their kind advice while preparing the manuscript and Dr. S. Miyazaki for giving us valuable advice during this study.  ...
