Evaluation of detailed transverse crack propagation toward thickness direction for CF/PEEK quasi-isotropic laminates under fatigue loading

Mechanical Engineering Journal, 2020
Carbon fiber (CF) reinforced polyether ether ketone (PEEK) laminates are applied to the members of transportation structures exposed to severe conditions, because carbon fibers and PEEK have excellent heat-resistant and chemical stability.

On Energy Release Rate for Propagation of a Straight Crack in a Cosserat Elastic Body

Mathematics, 2022
In this paper, we extend some results involving the energy release rate in the case of the propagation of a straight crack in an elastic solid. These results, approached by Gurtin and Yatomi in classical elasticity, are generalized in order to cover a ...

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Crack Growth and Energy Release Rate for an Angled Crack under Mixed Mode Loading

Applied Sciences, 2020
The evaluation of energy release rate with angle is still a challenging task in metal crack propagation analysis, especially for the mixed Mode I-II-III loading situation. In this paper, the energy release rate associated with stress intensity factors at

Effect of interfacial nanostructure on mode mixity in directly bonded carbon fiber reinforced thermoplastic laminates and aluminum alloy considering thermal residual stress

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
In recent years, for the aim of weight reduction of transportation equipment, carbon fiber reinforced thermoplastics (CFRTPs), which have high recyclability and formability, are becoming suitable for mass production. Additionally, with the development of

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Comment on ``Signal of Quark Deconfinement in the Timing Structure of Pulsar Spin-Down'' [PDF]

, 1998
This is a comment on a paper by Glendenning, Pei, and Weber (Phys. Rev. Lett., 79, 1603, 1997), where the authors gave an incorrect estimate of the event rate and neglected the important gravitational energy release.
