Between 2.5 and 4 billion years ago, a time known as the Archean eon, Earth’s weather could often be described as cloudy with a chance of asteroid.
Back then, it was not uncommon for asteroids or com...
Delayed-Input Non-Malleable Zero Knowledge and Multi-Party Coin Tossing in Four Rounds
delayed-input protocols non-malleable zero knowledge multi-party coin tossing
2017/9/26
4-round non-malleable zero knowledge (NMZK): Goyal et al. in FOCS 2014 showed the first 4-round one-one NMZK argument from one-way functions (OWFs). Their construction requires the prover to know the ...
Effects of delayed language exposure on spatial language acquisition by signing children and adults
sign language late acquisition spatial relations
2017/8/30
Deaf children born to hearing parents are exposed to language input quite late, which has long-lasting effects on language production. Previous studies with deaf individuals mostly focused on linguist...
Delayed-Choice Experiments and the Metaphysics of Entanglement
Delayed-choice experiments double-slit experiment entanglement swapping quantum eraser realism
2016/6/13
Delayed-choice experiments in quantum mechanics are often taken to undermine a realistic interpretation of the quantum state. More specifically, Healey has recently argued that the phenomenon of delay...
The Effect of Very High Magnetic Fields on the Delayed Fluorescence from Photosynthetic Reaction Centers
Reactioncenter Photosynthesis Bacterialphotosynthesis Delayedfluorescence Magneticfieldeffect (Rb. sphaeroides)
2016/5/23
Delayed fluorescence is observed from quinone-depleted Rhodobacter sphaeroides reaction centers due to re-formation of the excited state of the special pair electron donor from the initially formed ra...
Delayed Deproteinization Causes Methodological Errors in Amino Acid Levels in Plasma Stored at Room Temperature or -20°C
Amino Acid Assay Plasma Concentration Deproteinization Storage Blood Sample
2016/5/3
Deproteinization has been recognized as a prerequisite for amino acid analysis of plasma samples. For plasma stored at room temperature, delaying deproteinization for 30, 60 or 120 minutes did not res...

Introduction: A late-developing infection after an uneventful initial spinal instrumentation procedure is rare. Delayed infection and new fistula formation have been reported from a few months to 13 y...
2:1 Resonance in the delayed nonlinear Mathieu equation
Averaging Degenerate Hopf Delay Nonlinear Mathieu Parametric excitation
2015/8/27
We investigate the dynamics of a delayed nonlinear Mathieu equation:¨ x + (δ + εα cost)x + εγx 3 = εβx(t − T) in the neighborhood of δ = 1/4. Three different phe-nomena are combined in this syst...
Hopf Bifurcations in Two-Player Delayed Replicator Dynamics
Hopf Bifurcations Two-Player Delayed Replicator Dynamics
2015/8/26
We investigate the dynamics of two-strategy replicator equa-tions in which competition between strategies is delayed by a given time interval T. Taking T as a bifurcation parameter, we demonstrate the...
