An essential spectra mapping theorem
Journal of Mathematical Analysis and Applications, 1976 AbstractLet T be a closed operator on a Hilbert Space H, such that α ϵ p(T), the resolvent of T. Set A = (T − αI)−1. For μ ≠ 0, define λ such that (λ − α)μ = 1. It is shown that λ ϵ essential spectra of T iff μ ϵ essential spectra of A for various definitions of the essential spectra. A number of immediate corollaries are then derived.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Geomorphotectonic approach to geology of the Viñales National Park, Cuba
Journal of MapsThe geological substratum of Viñales National Park is crossed by fractures and over-thrusts. It includes siliciclastic (Jurassic San Cayetano Formation), carbonate (Late Jurassic to Early Eocene Jagua, Guasasa, Pons and Ancón Formations) and olistostrome

Incompressible maps of surfaces and Dehn filling
, 2004 We prove results showing that the existence of essential maps of surfaces in a manifold M obtained from a 3-manifold M by Dehn filling implies the existence of essential maps of surfaces in ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Essential maps exist from 𝐵𝑈 to 𝐶𝑜𝑘𝑒𝑟𝐽
, 1986 We show that [ BU,coker J ] ≠ 0 [{\text {BU,coker}}\,J] \ne 0 but that there are no infinite loop maps from BU to coker J J . The proofs involve the Segal

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 ...

Visualizing pathway on 3D maps for an interactive user navigation in mobile devices [PDF]
, 2019 3D maps have become an essential tool for navigation aid. The aim of a navigation aid is to provide an optimal route from the current position to the destination.

Halos and undecidability of tensor stable positive maps
, 2022 A map $\mathcal{P}$ is tensor stable positive (tsp) if $\mathcal{P}^{\otimes n}$ is positive for all $n$, and essential tsp if it is not completely positive or completely co-positive. Are there essential tsp maps? Here we prove that there exist essential

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
