Dynamics of Force-Induced DNA Slippage [PDF]

Physical Review Letters, 2004
We study the basepairing dynamics of DNA with repetitive sequences where local strand slippage can create, annihilate, and move bulge loops. Using an explicit theoretical model, we find a rich dynamical behavior as a function of an applied shear force f: reptation-like dynamics at f=f_c with a rupture time scaling as N^3 with its length N, drift ...

Runners on footbridges – a new VGRF model for heel strike running technique [PDF]

MATEC Web of Conferences, 2019
In the paper the models of dynamic forces generated by people running referred to two running techniques i.e. forefoot strike running and heel strike (rearfoot strike) running are presented.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Theoretical assessment of the distribution of dynamic interaction forces of the "rolling stock-track" system along the length of subway railway switches

Збірник наукових праць Державного університету інфраструктури та технологій: серія "Транспортні системи і технології"
One of the peculiarities for switch operation is the increased level of force interaction between the bearing elements of the switch and the rolling stock chassis, which causes increased requirements for strength, stability, reliability and durability ...

Loading of the hip and knee joints during whole body vibration training.

PLoS ONE, 2018
During whole body vibrations, the total contact force in knee and hip joints consists of a static component plus the vibration-induced dynamic component.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Statistical comparison of fleet types on track forces in Isfahan metro using field test data [PDF]

International Journal of Railway Research
The maintenance of a railway track in the urban rail fleet includes an intensive schedule of maintenance operations, which must be carried out by personnel during night time shift to ensure the safety of the system.
