Automated model discovery for tensional homeostasis: Constitutive machine learning in growth and remodeling.

We present a built-in physics neural network architecture, known as inelastic Constitutive Artificial Neural Network (iCANN), to discover the inelastic phenomenon of tensional homeostasis. In this course, identifying the optimal model and material parameters to accurately capture the macroscopic behavior of inelastic materials can only be accomplished with significant expertise, is often time-consuming, and prone to error, regardless of the specific inelastic phenomenon. To address this challenge, built-in physics machine learning algorithms offer significant potential.

Selection of volatile markers for rubbery rot in apple fruit caused by Phacidiopycnis washingtonensis.

Although a major share of postharvest losses of apples is due to fungal fruit rots, their timely detection is difficult in commercial bulk-storage rooms. Therefore, a method was developed to identify the volatile markers of fruit naturally infected by Phacidiopycnis washingtonensis, a common storage-rot fungus of Northern Europe, and North and South America. Potato dextrose agar, apple juice agar, and fruit of the apple cultivar 'Nicoter' were inoculated with P.

Mechanical modeling of the petiole-lamina transition zone of peltate leaves.

Plant leaves have to deal with various environmental influences. While the mechanical properties of petiole and lamina are generally well studied, only few studies focused on the properties of the transition zone joining petiole and lamina. Especially in peltate leaves, characterised by the attachment of the petiole to the abaxial side of the lamina, the 3D leaf architecture imposes specific mechanical stresses on the petiole and petiole-lamina transition zone.

Goal-directed colloid versus crystalloid therapy and microcirculatory blood flow following ischemia/reperfusion.

Objective: Ischemia/reperfusion can impair microcirculatory blood flow. It remains unknown whether colloids are superior to crystalloids for restoration of microcirculatory blood flow during ischemia/reperfusion injury. We tested the hypothesis that goal-directed colloid - compared to crystalloid - therapy improves small intestinal, renal, and hepatic microcirculatory blood flow in pigs with ischemia/reperfusion injury.

Mechanical modeling of the maturation process for tissue-engineered implants: Application to biohybrid heart valves.

The development of tissue-engineered cardiovascular implants can improve the lives of large segments of our society who suffer from cardiovascular diseases. Regenerative tissues are fabricated using a process called tissue maturation. Furthermore, it is highly challenging to produce cardiovascular regenerative implants with sufficient mechanical strength to withstand the loading conditions within the human body.
