The triceps surae performs vital functions during locomotion and possesses shock-absorbing capacity. The injury rate of the Achilles tendon is higher in males than females. Quantification of the triceps surae muscle force outputs across sexes has not been determined.

This study presents the experimental characterization of pre-reactive intermediates in the furan-acrolein Diels-Alder reaction using high-resolution rotational spectroscopy. Three distinct isomers were identified, with π-π stacking unexpectedly prevailing over hydrogen-bonded structures, and the structure being slightly more stable than . The computationally affordable yet accurate XYG3 method, validated against benchmark CCSD(T) calculations, accurately reproduced the energetic ordering of the isomers.

Arterial thrombi formed under high shear rates (~15,000/s) must withstand substantial forces to occlude arteries, as occurs in myocardial infarction or ischemic stroke, driving the need to understand the structural features responsible for their strength. We used scanning electron microscopy and immunofluorescence microscopy to characterize the structure of in vitro high shear thrombi. We show that the occlusive portion of the thrombus consists of a thick, transverse cable spanning the channel width.

Initially, the effects of sheet combinations for joining two sheets, including 780 MPa steel and A5052 aluminum alloy sheets, on the joined cross-sectional shapes of the sheets in a clinch-bonding process and the tension-shear load of joined sheets were investigated. The effect of an adhesive on the amounts of the interlock and the minimum thickness in the upper sheet was not large, whereas the effect of the sheet combination was observed. Subsequently, for joining the upper 980 MPa ultra-high-strength steel and lower aluminum alloy sheets in the clinch-bonding process, the effects of the die shape, punch velocity, and sheet holding force on the joinability were investigated.

This paper describes the development of a new hybrid composite for the metal joints of aluminium and glass fibre composite adherents. The aluminium adherend is manufactured using friction stir-formed studs that are inserted into the composite adherend in the through-thickness direction during the composite manufacturing process, where the dry fibres are displaced to accommodate the studs before the resin infusion process. The materials used were AA6082-T6 aluminium and plain-woven E-glass fabric reinforced epoxy, with primary applications in naval vessels.
