Analysis of three multilevel security architectures [PDF]

Proceedings of the 2007 ACM workshop on Computer security architecture, 2007
Various system architectures have been proposed for high assurance enforcement of multilevel security. This paper provides an analysis of the relative merits of three architectural types -- one based on a security kernel, another based on a traditional separation kernel, and a third based on a least-privilege separation kernel.

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.

The Influence of Public Corruption and Human Values on Trust in the Police: A European Cross-National Perspective

Kyiv-Mohyla Law and Politics Journal, 2019
Police forces are an important part of every democratic system and depend on societal legitimacy to perform their duties. Societal legitimacy stems from compliance with binding principles, like human rights and national law, and from broad acceptance ...

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes

Advanced Functional Materials, EarlyView.
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

The Effect of Classroom Composition and Size on Learning Outcomes for Italian and Immigrant Students in High School

Journal of Educational, Cultural and Psychological Studies, 2018
Students cannot change the composition and the size of the classroom they attend, and the effect of these variables on achievement is a source of educational inequality. In this study, based on a representative sample of Italian high school students (N =

A multilevel analysis of tuberculosisassociated factors [PDF]

Revista de Salud Pública, 2009
Evaluating the association between TB and AIDS and estimating the determinant effects and factors for TB incidence rates in Brazilian metropolitan regions from 2001 to 2003.A Poisson longitudinal multilevel model was fitted to the annual TB case number by municipality and year, including the population as an offset variable, and AIDS incidence by ...

Memristor‐Driven Active‐Matrix Organic Light‐Emitting Diode for Energy Efficient and High‐Resolution Displays

Advanced Functional Materials, EarlyView.
This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Dual‐Inductive and Programmable Switching: A New Paradigm in Ionic Interface‐Controlled Perovskite Memory

Advanced Functional Materials, EarlyView.
A fully programmable, dual‐inductive switchable halide perovskite memristor is demonstrated through precise BDAI2‐mediated interface engineering. This ion‐modulating layer suppresses stochastic filamentary growth, enabling stable, non‐filamentary switching via dynamic barrier modulation.

Gastric adenocarcinoma burden and late‐stage diagnosis in Latino and non‐Latino populations in the United States and Texas, during 2004–2016: A multilevel analysis

Cancer Medicine, 2021
Background Gastric cancer disproportionately affects Latinos, but little is known about regional effects and risk factors. We compared primary incidence, late‐stage diagnosis, and risk factors for gastric adenocarcinoma (GCA) from 2004 to 2016 in Latinos
