In my Wish List, an Automated Tool for Fail-Secure Design Analysis: an Alloy-Based Feasibility Draft [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
A system is said to be fail-secure, sometimes confused with fail-safe, if it maintains its security requirements even in the event of some faults.

Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

Formality properties of finitely generated groups and Lie algebras

open access: yes, 2019
We explore the graded and filtered formality properties of finitely generated groups by studying the various Lie algebras over a field of characteristic 0 attached to such groups, including the Malcev Lie algebra, the associated graded Lie algebra, the ...

Stabilized Cellulase in Chitosan–Polyvinyl Alcohol Biopolymer Beads for Sustainable Enzymatic Deinking of Recycled Paper

open access: yesChemistryOpen, EarlyView.
A stable and reusable biocatalyst, cellulase@Cs/PVA/Ga, is engineered by immobilizing cellulase onto glutaraldehyde‐activated chitosan (Cs) and coating it with polyvinyl alcohol. This composite system enhances enzymatic stability and efficiency for the sustainable deinking of recycled newspaper, offering a green alternative to harsh chemical treatments.

Effectiveness of inorganic and organic mulching for soil salinity and sodicity control in a grapevine orchard drip-irrigated with moderately saline waters

open access: yesSpanish Journal of Agricultural Research, 2014
Soil mulching is a sensible strategy to reduce evaporation, accelerate crop development, reduce erosion and assist in weed control, but its efficiency for soil salinity control is not as well documented.

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

open access: yesRare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.
