Formally Verified EVM Block-Optimizations

open access: yes, 2023
AbstractThe efficiency and the security of smart contracts are their two fundamental properties, but might come at odds: the use of optimizers to enhance efficiency may introduce bugs and compromise security. Our focus is on (Ethereum Virtual Machine) block-optimizations, which enhance the efficiency of jump-free blocks of opcodes by eliminating ...

Improved Extraction of the Neurotoxin of Stenocarpella maydis Using an Artificial Rumen

open access: yesVeterinary Medicine International
Due to the low yield of diplonine obtained when isolated from Stenocarpella maydis (Berk.) Sutton (formerly Diplodia maydis (Berk.) Sacc., the present research was aimed to find a more efficient method of preparing diplonine to confirm its neurological ...

Resolving the Structural Duality of Graphene Grain Boundaries

open access: yesAdvanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

A game-based learning method to teach project management – the case of the earned value management

open access: yesCogent Education, 2023
The earned value management (EVM) is a project management method for monitoring and controlling project expenditure and progress. Teaching EVM is challenging as the method may appear theoretical, mathematical, and disconnected from the uncertainty of ...

Extracellular Vesicles-Mimetic Encapsulation Improves Oncolytic Viro-Immunotherapy in Tumors With Low Coxsackie and Adenovirus Receptor

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
The oncolytic adenovirus (Adv) exhibited poor infection efficiency in tumor cells with low coxsackie and adenovirus receptor (CAR) on the cell surface, which limits the therapeutic efficacy of the Adv-mediated cancer gene therapy.
