Witten index, spectral shift function and spectral flow

, 2017
The notion of spectral flow has been introduced by Atiyah and Lustzig and is an important tool in geometry. In 1976 Atiyah, Patodi and Singer suggested that a path of elliptic operators on odd dimensional compact manifolds the spectral flow can be computed via the Fredholm index of so-called `suspension', which is a first order elliptic operator on a ...

Structural biology of ferritin nanocages

FEBS 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 ...

High-Throughput Switchgrass Phenotyping and Biomass Modeling by UAV

Frontiers in Plant Science, 2020
Unmanned aerial vehicle (UAV) technology is an emerging powerful approach for high-throughput plant phenotyping field-grown crops. Switchgrass (Panicum virgatum L.) is a lignocellulosic bioenergy crop for which studies on yield, sustainability, and ...

The Dust Emissivity Spectral Index in the Starless Core TMC-1C [PDF]

, 2009
In this paper we present a dust emission map of the starless core TMC-1C taken at 2100 microns. Along with maps at 160, 450, 850 and 1200 microns, we study the dust emissivity spectral index from the (sub)millimeter spectral energy distribution, and find

Beyond NDVI- Spectral indexing of biomass

Journal of Agricultural Informatics, 2019
The use of both terrestrial and satellite sensors often lacks the specific knowledge that makes them more effective. There are many reasons for this, one of them is agricultural digitalization to facilitate data availability and shortened automatic spectral indexing, but interpretation requires special remote sensing and agricultural knowledge.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
