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

open access: yesFEBS 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.

DESIGN AND PROPERTIES OF HOT MIXTURE POROUS ASPHALT FOR SEMI-FLEXIBLE PAVEMENT APPLICATIONS [PDF]

open access: yes, 2005
Semi-flexible pavement consists of selected porous asphalt mixture filled with cementitious slurry. This new type of pavement has prospects to be designed as a high deformation resistant pavement (Setyawan et al, 2001).

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Effects Variability Number of Load Repetitions on the Optimum Thickness of Asphalt Layer with Respect to Fatigue and Rutting Behaviour on the Sand Bed Soil Area

open access: yesPolytechnic Journal, 2023
This study investigates the effect of the variability of a number of load repetitions on the asphalt layer thickness, and also the elastic modulus of pavement materials on the behaviour of flexible pavement structural on the sand bed soil with respect to

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

The Reflective Cracking in Flexible Pavements [PDF]

open access: yesRomanian Journal of Transport Infrastructure, 2013
Abstract Reflective cracking is a major concern for engineers facing the problem of road maintenance and rehabilitation. The problem appears due to the presence of cracks in the old pavement layers that propagate into the pavement overlay layer when traffic load passes over the cracks and due to the temperature variation.
