Design and Pictet–Spengler enabled synthesis of carboxamide-substituted imidazo[1,2-a]quinoxalines as dual EGFR and tubulin targeting anticancer agents [PDF]

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry
In this study, we report the Pictet–Spengler enabled synthesis of a series of eighteen carboxamide-substituted imidazo[1,2-a]quinoxaline derivatives (JRC-1-JRC-18) targeting epidermal growth factor receptor (EGFR) and tubulin.

Expression and Analysis of Scale Effect and Anisotropy of Joint Roughness Coefficient Values Using Confidence Neutrosophic Number Cubic Values [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
: The JRC data collected from a rock mass joint surface difficultly obtain enough large-scale JRC sample data, but small-scale JRC sample data, which usually contain indeterminate and incomplete information due to the limitation of the measurement ...

Machine learning-based optimization of photogrammetric JRC accuracy

open access: yesScientific Reports
To improve the accuracy of photogrammetric joint roughness coefficient (JRC) estimation, this study proposes two optimization models based on ground sample distance (GSD), point density, and the root mean square error (RMSE) of checkpoints.

Suggested New Statistical Parameter for Estimating Joint Roughness Coefficient considering the Shear Direction

open access: yesAdvances in Civil Engineering, 2021
The 10 standard roughness joint profiles provided a visual comparison to get the joint roughness coefficient (JRC) of rock joint surface, but the accuracy of this method is influenced by human factors.

Experimental study of uniaxial compressive mechanical properties of rough jointed rock masses based on 3D printing

open access: yesApplied Rheology, 2023
Roughness and inclination are important factors affecting the strength and deformation properties of jointed rock masses. Serrated joint specimens with varying joint roughness coefficient (JRC) and inclination angle were manufactured by 3D printing ...
