Traumatic brain injury(TBI)is a public health problem with an undue economic burden that impacts nearly every age,ethnic,and gender group across the globe(Capizzi et al.,2020).TBIs are often sustained during a dynamic range of exposures to energetic environmental forces and as such outcomes are typically heterogeneous regarding severity and pathology(Capizzi et al.,2020).

Optical tweezers have elucidated numerous biological processes, particularly by enabling the precise manipulation and measurement of tension. One question concerns the biological relevance of these experiments and the generalizability of these experiments to wider biological systems. Here, we categorize the applicability of the information garnered from optical tweezers in two distinct categories: the direct relevance of tension in biological systems, and what experiments under tension can tell us about biological systems, while these systems do not reach the same tension as the experiment, still, these artificial experimental systems reveal insights into the operations of biological machines and life processes.

The Chinese Altai is an important constituent of the Central Asian Orogenic Belt， a prominent Phanerozoic accretionary orogenic belt. Oceanic-continental subduction processes during the Cambrian–Carboniferous and intracontinental extension from the Triassic onwards have been well constrained in the Chinese Altai， the southwestern portion of the CAOB. Characterizing the petrogenetic evolution of the Chinese Altai during the Permian has， therefore， been considered critical to enhancing our understanding of the tectonic transformations that occurred in this region. Despite this， the tectonic environment of the Chinese Altai during this period remains equivocal. To address this deficiency， this contribution characterizes the age of formation and geochemical composition of the jiangjunshan pluton located in the southern portion of the Chinese Altai. Zircon U-Pb geochronology demonstrates that the gabbro and two-mica alkali feldspar granite， which comprise the main body of the jiangjunshan pluton， formed at ca. 272 ± 3.5 and 272 ± 1.6 Ma， respectively. Geochemically， the gabbro is depleted in light rare earth elements （LREE）， has low Nb/Yb （0.39–0.46） and Ti/V （23.7–25.3） ratios， exhibits trace-element characteristics resembling normal mid-ocean ridge basalts （N-MORB）， but is depleted in Nb and Ta similar to island arc basalts. The depleted Hf and Nd isotope compositions (εHf（t） = +0.60 to +4.63， εNd（t） = +6.32 to +7.80) of the gabbro， coupled with the weak correlation between εNd（t） values and SiO2contents， suggest that the magma from which it crystallized was slightly contaminated by crustal material during its evolution. Based on the Sm， Yb， and La contents， it is inferred that the melt from which the gabbro crystallized originated from approximately 8–20% partial melting of spinel lherzolite mantle. The depleted Hf and Nd isotope compositions (εHf（t） = +6.81 to +9.10， εNd（t） = +0.79 to +1.45) of the granite， combined with petrographic observations （e.g.， absent of the
