Seeable universe and its accelerated expansion: an observational test [PDF]

open access: yes, 2013
From the equivalence principle, one gets the strength of the gravitational effect of a mass $M$ on the metric at position r from it. It is proportional to the dimensionless parameter $\beta^2 = 2GM/rc^2$, which normally is $

Flexural Behavior of Epoxy under Accelerated Hygrothermal Conditions

open access: yesFibers, 2017
Fibers by themselves have a limited use in engineering applications since they cannot transmit loads from one to another; therefore, the matrix material plays an important role in the overall function of the fiber reinforced polymer (FRP) composites ...

Failure Reason of PI Test Samples of Neural Implants

open access: yesSensors, 2023
Samples that were meant to simulate the behavior of neural implants were put into Ringer’s solution, and the occurring damage was assessed. The samples consist of an interdigitated gold-structure and two contact pads embedded between two Polyimide layers,
