11221por Pimenta, Sara, Rodrigues, José A., Machado, Francisca, Ribeiro, João F., Maciel, Marino J., Bondarchuk, Oleksandr, Monteiro, Patricia, Gaspar, João, Correia, José H., Jacinto, Luis“…The double-layer design and fabrication approach implemented also provides additional stiffening just sufficient to prevent probe buckling during brain insertion. This approach avoids typical laborious augmentation strategies used to increase flexible probes’ mechanical rigidity while allowing a small brain insertion footprint. …”

11227Flexural Strength of Internally Stiffened Tubular Steel Beam Filled with Recycled Concrete Materialspor Al Zand, Ahmed W., Ali, Mustafa M., Al-Ameri, Riyadh, Badaruzzaman, Wan Hamidon Wan, Tawfeeq, Wadhah M., Hosseinpour, Emad, Yaseen, Zaher Mundher“…The flexural strength of Slender steel tube sections is known to achieve significant improvements upon being filled with concrete material; however, this section is more likely to fail due to buckling under compression stresses. This study investigates the flexural behavior of a Slender steel tube beam that was produced by connecting two pieces of C-sections and was filled with recycled-aggregate concrete materials (CFST beam). …”

11230“…Due to the geometric limitations of CICNT height and substrate curvature, all other microscale defects were significantly more present on samples with a small radius of curvature and a tall CICNT forest (p < 0.05). These buckling and warping types of defects were attributed to the increase in circumferential compression as the forest grows as well as the van der Waals interactions between the nanotubes. …”

These findings suggest that species differences in the capacity for hair cell regeneration may be attributable in part to the differences in the stiffness and contractility of the actin cytoskeletal elements that reinforce adherens junctions and participate in regulation of the cell cycle.…”

Here, the trap reopening mechanics in two different D. muscipula clones, producing normal‐sized (N traps, max. ≈3 cm in length) and large traps (L traps, max. ≈4.5 cm in length) are investigated. …”
