On an unsupervised method for parameter selection for the elastic net

Mathematics in Engineering, 2022
Despite recent advances in regularization theory, the issue of parameter selection still remains a challenge for most applications. In a recent work the framework of statistical learning was used to approximate the optimal Tikhonov regularization ...

Model‐Driven Engineering for Digital Twins: Opportunities and Challenges

Systems Engineering, Volume 28, Issue 5, Page 659-670, September 2025.
ABSTRACT Digital twins are increasingly used across a wide range of industries. Modeling is a key to digital twin development—both when considering the models which a digital twin maintains of its real‐world complement (“models in digital twin”) and when considering models of the digital twin as a complex (software) system itself.

Have significant biodiversity values been protected from industrial logging across Australia?

Conservation Science and Practice, Volume 7, Issue 8, August 2025.
Abstract Much of the planet's forest biodiversity is at risk from a range of threats. Threats include gaps in the protected area network and instances where these gaps are subject to intensive industrial logging. These gaps are referred to as optimal areas for protection and we sought to determine if certification schemes maintained the environmental ...

Temporary Intercropping With Forage or Industrial Crops Improves Yield and Weed Control in Cardoon (Cynara cardunculus var. altilis DC)

GCB Bioenergy, Volume 17, Issue 8, August 2025.
This study compared the traditional cardoon cropping system with the option of temporary intercropping during the first year of cultivation with treatments: Vicia villosa, Eruca sativa, and Camelina sativa. Results show that temporary intercropping reduced weed biomass by 24%, while intercropping with V. villosa increased cardoon yield (in the year II)

The boundary effect: Perceived post hoc accuracy of prediction intervals

Judgment and Decision Making, 2018
Predictions of magnitudes (costs, durations, environmental events) are often given as uncertainty intervals (ranges). When are such forecasts judged to be correct?

A Cell-Based Framework for Numerical Modeling of Electrical Conduction in Cardiac Tissue

Frontiers in Physics, 2017
In this paper, we study a mathematical model of cardiac tissue based on explicit representation of individual cells. In this EMI model, the extracellular (E) space, the cell membrane (M), and the intracellular (I) space are represented as separate ...

Construction of System Descriptions in SIMULA and DELTA

DAIMI Report Series, 1978
In this paper we discuss the two construction strategies: decomposition and composition (''top-down'' and ''bottom-up'' ). We consider the concepts of subsystems and aggregates as developed in the DELTA project, which may assist us when using the two construction strategies.

Do calcium channel blockers applied to cardiomyocytes cause increased channel expression resulting in reduced efficacy?

npj Systems Biology and Applications
In the initial hours following the application of the calcium channel blocker (CCB) nifedipine to microtissues consisting of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), we observe notable variations in the drug’s efficacy ...
