Phases of scrambling in eigenstates [PDF]

open access: yes, 2019
We use the monodromy method to compute expectation values of an arbitrary number of light operators in finitely excited ("heavy") eigenstates of holographic 2D CFT.

Stimulus and transducer effects on threshold [PDF]

open access: yesInternational Journal of Audiology, 2014
This study examined differences in thresholds obtained under Sennheiser HDA200 circumaural earphones using pure tone, equivalent rectangular noise bands, and 1/3 octave noise bands relative to thresholds obtained using Telephonics TDH-39P supra-aural earphones.Thresholds were obtained via each transducer and stimulus condition six times within a 10-day

Bottomonium Vector Resonances and Threshold Effects

open access: yesActa Physica Polonica B Proceedings Supplement, 2023
The bottomonium spectrum is the perfect testing ground for the confining potential and unitarisation effects. The bottom quark is about three times heavier than the charm quark, so that $b\bar{b}$ systems probe primarily the short-range part of that potential.

Method of estimating the effective zone induced by rapid impact compaction

open access: yesScientific Reports, 2021
This paper proposes a method for estimating the effective zone, including effective depth and effective range of compaction degree, from rapid impact compaction (RIC) on sand layer whose fines content is less than 10%.

Avoiding critical thresholds through effective monitoring

open access: yesProceedings of the Royal Society B: Biological Sciences, 2022
A major challenge in sustainability science is identifying targets that maximize ecosystem benefits to humanity while minimizing the risk of crossing critical system thresholds. One critical threshold is the biomass at which populations become so depleted that their population growth rates become negative—depensation. Here, we evaluate how the value of

Stochastic Behavior of Effective Field Theories Across Threshold

open access: yes, 1996
We explore how the existence of a field with a heavy mass influences the low energy dynamics of a quantum field with a light mass by expounding the stochastic characters of their interactions which take on the form of fluctuations in the number of (heavy

Study of the relationships between structural parameters of disordered porous media and effective diffusivity by Kinetic Monte Carlo

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2012
The effect of porosity and pore size on transport properties of hydrogen in a disordered porous medium is studied by kinetic Monte Carlo. The randomness of the pores in the medium, inscribed inside a simple cubic lattice, was corroborated by calculating

Effective continuum threshold for vacuum-to-bound-state correlators

open access: yes, 2009
We formulate a new algorithm for obtaining the effective continuum threshold in vacuum-to-bound-state correlators - the basic objects for the calculation of hadron form factors in the method of light-cone sum rules in QCD.

Threshold Effects of Energy Price Changes [PDF]

open access: yesSSRN Electronic Journal, 2000
This paper presents a theoretical model emphasising energy investments’characteristics of uncertainty and irreversibility. The theoretical modelsuggests threshold effects. Firms are induced to substitute away from energyonly if prices of energy exceed a certain threshold level and they reverse thetechnology only if energy prices are low enough ...
