Improvement of Some Physical and Sensing Properties of Nanostructured Cadmium Oxide: Manganese Thin Films

Proceedings of the International Conference on Applied Innovations in IT
The spray pyrolysis technique (SPT) was employed for depositing thin films of Mn-doped CdO. The structural analysis through XRD confirms films polycrystallinity with a cubic phase. AFM analysis reveals adecline in particle size and surface roughness. The

Notes on CSPs and Polymorphisms

CoRR, 2022
These are notes from a multi-year learning seminar on the algebraic approach to Constraint Satisfaction Problems (CSPs). The main topics covered are the theory of algebraic structures with few subpowers, the theory of absorbing subalgebras and its applications to studying CSP templates which can be solved by local consistency methods, and the dichotomy

Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

The Expressiveness of CSP With Priority

Electronic Notes in Theoretical Computer Science, 2015
AbstractThe author previously [A.W. Roscoe, On the expressiveness of CSP, https://www.cs.ox.ac.uk/files/1383/expressive.pdf, 2011; A.W. Roscoe, Understanding concurrent systems, Springer 2010] defined CSP-like operational semantics whose main restrictions were the automatic promotion of most τ actions, no cloning of running processes, and no negative ...
