Oxygen Isotopes and Volatiles in Martian Meteorite [PDF]

, 2013
Oxygen isotopes were measured in mineral separates from martian meteorites using laser fluorination and were found to be remarkably uniform in both δ18O and Δ17O, suggesting that martian magmas did not assimilate aqueously altered crust regardless of any

Volatility and arbitrage [PDF]

The Annals of Applied Probability, 2018
The capitalization-weighted total relative variation $\sum_{i=1}^d \int_0^\cdot μ_i (t) \mathrm{d} \langle \log μ_i \rangle (t)$ in an equity market consisting of a fixed number $d$ of assets with capitalization weights $μ_i (\cdot)$ is an observable and nondecreasing function of time.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Plant volatiles and components influencing behavior of the field slug, deroceras-reticulatum (mull)

, 1980
A new bioassay was devised in which slugs were allowed to follow trails of the aqueous volatiles isolated from plants by vacuum distillation. Volatiles from lettuce, carrot and dandelion induced greatest response.

Volatility of Volatility: A Simple Model-Free Motivation [PDF]

Wilmott, 2011
Our goal is to provide a simple, intuitive and model-free motivation for the importance of volatility-of-volatility in pricing certain kinds of exotic and structured products.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Model for Determining the Origin of Lunar Volatiles Based on Their Composition: Application to NASA’s VIPER and Other Landed Missions

The Planetary Science Journal
Lunar volatiles provide a potentially pristine record of the history of the Earth–Moon system in terms of both geologic activity and delivery of volatiles from the outer solar system.

A review of the volatiles from the healthy human body

, 2014
A compendium of all the volatile organic compounds (VOCs) emanating from the human body (the volatolome) is for the first time reported. 1840 VOCs have been assigned from breath (872), saliva (359), blood (154), milk (256), skin secretions (532) urine ...

Improvement of a synthetic lure for Anopheles gambiae using compounds produced by human skin microbiota [PDF]

, 2011
Background - Anopheles gambiae sensu stricto is considered to be highly anthropophilic and volatiles of human origin provide essential cues during its host-seeking behaviour.

Achieving High ON State Current through Ferroelectric Polarization‐Dependent Interfacial Resistance Switching in Undoped Orthorhombic HfO2 Films

Advanced Functional Materials, EarlyView.
Ferroelectric tunnel junction devices based on epitaxial undoped ferroelectric HfO2 films demonstrate stable switching endurance of over 106 switching cycles, low write voltages of ±3 V, 16 measured resistance states, and neuromorphic capability.
