Classicality Criteria

open access: yesJournal of Mathematical Physics, 2002
We present two possible criteria quantifying the degree of classicality of an arbitrary (finite dimensional) dynamical system. The inputs for these criteria are the classical dynamical structure of the system together with the quantum and the classical ...

Thermonuclear Burn Criteria [PDF]

open access: yesFusion Science and Technology, 2012
After more than 50 years of fusion research the time has arrived when fusion processes in experimental plasmas are increasingly getting important. In JET the genuine fuel (deuterium-tritium) of a fusion reactor was used for the first time in late 1991, in TFTR the same happened in 1993, and in JET an extended period of experiments of this kind was ...

STABILITY CRITERIA [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1978
Three approaches to the determination of behavioral stability were examined. In the first, a learning curve was fit to acquisition data (from Cumming and Schoenfeld, 1960), and the “experiment” stopped when the data approached sufficiently close to the theoretical asymptote. In the second, the data were analyzed for variability and linear and quadratic

Dual criteria decisions [PDF]

open access: yesJournal of Economic Psychology, 2014
The most popular models of decision making use a single criterion to evaluate projects or lotteries. However, decision makers may actually consider multiple criteria when evaluating projects. We consider a dual criteria model from psychology. This model integrates the familiar tradeoffs between risk and utility that economists traditionally assume ...

Criteria for virtual fibering [PDF]

open access: yes, 2008
We prove that an irreducible 3-manifold whose fundamental group satisfies a certain group-theoretic property called RFRS is virtually fibered. As a corollary, we show that 3-dimensional reflection orbifolds and arithmetic hyperbolic orbifolds defined by ...

Commutator criteria for strong mixing [PDF]

open access: yes, 2014
We present new criteria, based on commutator methods, for the strong mixing property of discrete flows $\{U^N\}_{N\in\mathbb Z}$ and continuous flows $\{{\rm e}^{-itH}\}_{t\in\mathbb R}$ induced by unitary operators $U$ and self-adjoint operators $H$ in ...

Characterization, occurrence, environmental behaviors, and risks of nanoplastics in the aquatic environment: Current status and future perspectives

open access: yesFundamental Research, 2021
Microplastics (MPs) are emerging contaminants that have attracted worldwide attention in recent years. Compared with MPs, nanoplastics (NPs) may exhibit greater toxicity and higher potential risks because of their unique physiochemical nanoscale ...

Authentication with Distortion Criteria [PDF]

open access: yes, 2005
In a variety of applications, there is a need to authenticate content that has experienced legitimate editing in addition to potential tampering attacks.

Exploring HONO production from particulate nitrate photolysis in representative regions of China: characteristics, influencing factors, and environmental implications [PDF]

open access: yesAtmospheric Chemistry and Physics
The production mechanism of atmospheric nitrous acid (HONO), an important precursor of the hydroxyl radical (OH), remains controversial. Few studies have explored the effects of particulate nitrate photolysis on HONO sources under different environment ...

A New Method for Ecological Risk Assessment of Combined Contaminated Soil

open access: yesToxics, 2023
Ecological risk assessment of combined polluted soil has been conducted mostly on the basis of the risk screening value (RSV) of a single pollutant. However, due to its defects, this method is not accurate enough.
