To establish what time is, as in Plato’s iconic definition (“moving image of eternity”, Timaeus 37d), one often has to emphasize its relation to what time is not. Time seems to be defined dialectically, in terms of what is not eternal, not extra-temporal, etc.

Forming limit serves as a critical metric in evaluating the formability of advanced sheet metals. Unlike the plane stress state in conventional sheet processing technologies, compressive normal stress and even more intricate stress states play a ...

CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Analysis of forming limits in metal forming processes
Forming limit plays a very important role in metal forming processes since it can be used to predict whether a blank will fracture or not. This paper examines the influence on forming limit of blank and fractured thickness.

Reconstructing enzyme evolution by protein engineering
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.
