Synthesis of Dynamic Masks for Infinite-Step Opacity

open access: yesIEEE Transactions on Automatic Control, 2020
We investigate the problem of synthesizing dynamic masks that preserve the infinite-step opacity in the context of discrete-event systems. Dynamic mask is an information acquisition mechanism that controls the observability of the system's events ...

Opacity calculation for target physics using the ABAKO/RAPCAL code

open access: yes, 2010
Radiative properties of hot dense plasmas remain a subject of current interest since they play an important role in inertial confinement fusion (ICF) research, as well as in studies on stellar physics.

Opacity, liquidity and disclosure requirements [PDF]

open access: yes, 2022
We present a model that links the opacity of an asset to its liquidity. We show that while low-opacity assets are liquid, intermediate levels of opacity provide incentives for investors to acquire private information, causing adverse selection and ...

The extragalactic background light revisited and the cosmic photon–photon opacity (Corrigendum) [PDF]

open access: yesAstronomy & Astrophysics, 2017
In addition to its relevant astrophysical and cosmological significance, the Extragalactic Background Light (EBL) is a fundamental source of opacity for cosmic high energy photons, as well as a limitation for the propagation of high-energy particles in ...

The Development of Understanding Opacity in Preschoolers: A Transition From a Coarse- to Fine-Grained Understanding of Beliefs

open access: yesFrontiers in Psychology, 2020
Intensionality (or opacity) is a core property of mental representations and sometimes understanding opacity is claimed to be a part of children’s theory of mind (evidenced with the false belief task).

Dust Opacities [PDF]

open access: yesEPJ Web of Conferences, 2015
Dust particles are the dominant source of opacity at (almost) all wavelengths and in (almost) all regions of protoplanetary disks. By this they govern the transport of energy through the disk and thus the thermal structure. Furthermore, their spectral properties determine the low resolution spectral signature observed at infrared wavelengths.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Social media, financial reporting opacity, and return comovement: Evidence from Seeking Alpha [PDF]

open access: yes, 2019
In this study, we develop a model to analyze the interplay between the coverage of a firm on social media, financial reporting opacity, and stock return comovement. Our model predicts a negative association between social media coverage and comovement as
