*Constrained* pseudorandom functions allow for delegating ``constrained'' secret keys that let one compute the function at certain authorized inputs---as specified by a constraining predicate---while ...
Constraining Pseudorandom Functions Privately
pseudorandom functions multilinear maps indistinguishability obfuscation
2015/12/18
In a constrained pseudorandom function (PRF), the holder of the master secret key can
derive constrained keys with respect to a boolean circuit C. The constrained key can be used to
evaluate the PRF...
Constraining the dynamics of volcanic eruptions by characterization of pumice textures
Phlegraean Fields Plinian eruptions vesicle textures magma ascent dynamics
2015/9/10
We have characterized the textures of pumice clasts from Phlegraean Fields to gain insights into the conduit
flow-dynamics of alkaline explosive eruptions. Vesicularities, vesicle number densities, a...
KINETIC CONSEQUENCES OF CONSTRAINING RUNNING BEHAVIOR
Ground reaction force, impact attenuation, shock
2015/3/17
It is known that impact forces increase with running velocity as well as when stride length increases.
Since stride length naturally changes with changes in submaximal running velocity, it was not c...
Constraining fault interpretation through tomographic velocity gradients: application to northern Cascadia
Constraining fault interpretation velocity gradients
2015/1/4
Spatial gradients of tomographic velocities are
seldom used in interpretation of subsurface fault structures.
This study shows that spatial velocity gradients can be used
effectively in identifying...

Constraining Stellar Feedback: Ionized Gas Structures In Local Starburst Galaxies
Pure sciences Ionized gas structures Interstellar medium Starburst galaxies Stellar feedback
2014/12/9
Stellar feedback, i.e., the return of mechanical energy from supernova explosions, and massive star and AGN winds to the interstellar medium, is one of the fundamental processes that shape galaxy evol...
Prevention from a community perspective facilitating and constraining factors perceived by nurses in local community health centers in the course of prevention and health promotion
Nursing Community Obstacles Stimulating Factors

The purpose of this paper is to explore the stimulating factors and the obstacles experienced by nurses in community health centres in their work with prevention and health promotion. We conducted the...
Constraining dynamical dark energy with a divergence-free parametrization in the presence of spatial curvature and massive neutrinos
Constraining dynamical dark energy divergence-free parametrization presence spatial curvature massive neutrinos
2012/2/21
In this paper, we report the results of constraining the dynamical dark energy with a divergence-free parameterization, $w(z) = w_{0} + w_{a}(\frac{\ln(2+z)}{1+z}-\ln2)$, in the presence of spatial cu...
Constraining density functional approximations to yield self-interaction free potentials
Constraining density functional approximations self-interaction free potentials
2011/8/18
Abstract: Self-interactions (SIs) are a major problem in density functional approximations and the source of serious divergence from experimental results. Here, we propose to constrain the effective l...
The WiggleZ Dark Energy Survey: constraining the evolution of Newton's constant using the growth rate of structure
constraining evolution constant using growth rate structure
2011/10/11
We constrain the evolution of Newton's constant using the growth rate of large-scale structure measured by the WiggleZ Dark Energy Survey in the redshift range $0.1 < z < 0.9$. We use this data in two...
