Small $E_8$ Instantons and Tensionless Non-critical Strings [PDF]

, 1996
T-duality is used to extract information on an instanton of zero size in the $E_8\times E_8$ heterotic string. We discuss the possibility of the appearance of a tensionless anti-self-dual non-critical string through an implementation of the mechanism ...

Glycolysis‐Derived Lactate Induces ACSL4 Expression and Lactylation to Activate Ferroptosis during Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Glycolysis‐derived lactate activates nucleus pulposus cell ferroptosis via Histon H3K18la‐mediated ACSL4 transcription and ACSL4 lactylation and aggravate intervertebral disc degeneration. Inhibiting glycolysis via gene silencing or chemical intervention reduces the production of lactate and ameliorates ferroptosis activation and nucleus pulposus ...

Precise Orbit Determination of CubeSats [PDF]

, 2022
CubeSats are faced with some limitations, mainly due to the limited onboard power and the quality of the onboard sensors. These limitations significantly reduce CubeSats' applicability in space missions requiring high orbital accuracy.

A Soft‐Soft Contact Triboelectric Nanogenerator with a Ternary Four‐Phase Structure for Self‐Powered High‐Efficiency Dust Removal on Mars

Advanced Science, EarlyView.
The frequent dust storms and charged dust particles on Mars pose significant challenges to the power generation efficiency and service life of solar panels during exploration missions. This paper proposes a novel wind‐driven ternary four‐phase soft‐soft contact triboelectric nanogenerator (FPS‐TENG) for dust removal.
