Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Magnetic-mechanical accumulator of kinetic energy

open access: yesAUTEX Research Journal, 2014
The paper focuses on the process of non-contacting kinetic energy accumulation at the dead-end positions of a reciprocating rectilinear motion with a variable stroke.

Rockfall Intensity under Seismic and Aseismic Conditions: The Case of Lefkada Island, Greece

open access: yesLand, 2023
Rockfall analysis is a multiparametric procedure with many uncertainties and the outputs are largely dependent on some critical engineering geological parameters involved in the used simulation model.

Kinetic energy and the equivalence principle [PDF]

open access: yesAmerican Journal of Physics, 1998
According to the general theory of relativity, kinetic energy contributes to gravitational mass. Surprisingly, the observational evidence for this prediction does not seem to be discussed in the literature. I reanalyze existing experimental data to test the equivalence principle for the kinetic energy of atomic electrons, and show that fairly strong ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Is ½ mυ² the Kinetic Energy or One-Half of the Kinetic Energy?

open access: yesJapan Journal of Research
In the 1680s, Leibniz experimentally proved that vis viva is the product of the mass and square ofvelocity, mυ2. In 1847, Helmholtz studied free fall and found that the work produced or consumed was(1/2)mυ2 = mgh, and suggested calling the work as vis viva.

Prompt neutrons from 236U fission fragments. [PDF]

open access: yes, 1971
Measurements were made of prompt neutron emission in the thermal neutron fission of 235U. The mean neutron emission per fragment was obtained for particular values of the fragment mass and total kinetic energy.

α‐Synuclein aggregation landscape from phase separation to neurotoxic intermediates

open access: yesFEBS Letters, EarlyView.
Alpha‐synuclein aggregation in Parkinson's disease involves a complex landscape of transient intermediates, including oligomers, fibrils and liquid–liquid phase separation (LLPS). A view is emerging in which LLPS maturation into solid‐like condensates may contribute to the formation of neurotoxic species.

Transient Stability Control Based on Kinetic Energy Changes Measured by Synchronized Angular Velocity

open access: yesEnergies, 2021
Real-time transient stability studies are based on voltage angle measures obtained with phasor measurement units (PMUs). A more precise calculation to address transient stability is obtained when using the rotor angles. However, these values are commonly

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
