Phosphorylation of eIF2α controls translation initiation by restricting the levels of active eIF2-GTP/Met-tRNAi ternary complexes (TC). This modulates the expression of all eukaryotic mRNAs and contributes to the cellular integrated stress response. Key to controlling the activity of eIF2 are translation factors eIF2B and eIF5, thought to primarily function with eIF2-GDP and TC respectively. Us...

Fate of light hadronic excitations above the critical temperature Tc of the QCD phase transition was first investigated 20 years ago.1,2 In Ref. 1 whose title is “Fluctuation effects in hot quark matter: precursors of chiral transition at finite temperature”, the hadrinic modes above Tc were discussed in connection with the critical fluctuation associated with chiral symmetry restoration: The a...

From: WSS TC Chairs To: Karl Best, OASIS Dear Karl, Per the OASIS process document [1], we Kelvin Lawrence and Chris Kaler, co-Chairs of the WSS TC [2], have prepared the following document to accompany the submission from the WSS TC to OASIS of the Web Services Security specification and related documents for final approval as an OASIS standard. The TC voted to re-approve the documents [3], [4...

We have studied the spin dynamics in Pr0.63Sr0.37MnO3 above and below the Curie temperature TC = 301 K. Three distinct new features have been observed: a softening of the magnon dispersion at the zone boundary for T < TC , significant broadening of the zone boundarymagnons as T → TC , and no evidence for residual spin-wave like excitations just above TC . The results are inconsistent with doubl...

We present a quantitative analysis of finite frequency fluctuation conductivity above and below Tc in cuprate superconductors in zero dc magnetic field. In a YBa2Cu3O72d crystal showing a linear in temperature increase of the penetration depth at low temperatures, we find that two-dimensional ~2D! finite frequency Gaussian conductivity fluctuations above Tc cross over into a slower divergence o...

A new synthetic methodology of water-soluble gold and silver nanoparticles (AuNPs@TC and AgNPs@TC), using the antibiotic tetracycline (TC) as co-reducing and stabilizing agent, is reported. Both colloids exhibit high water stability. The average sizes obtained were 25±10 and 15±5 nm, respectively. Both composites were tested against TC-resistant bacteria, presenting an increasing antibacterial ...

Shewanella oneidensis MR-1 possesses a periplasmic [NiFe]-hydrogenase (MR-1 [NiFe]-H(2)ase) that has been implicated in H(2) production and oxidation as well as technetium [Tc(VII)] reduction. To characterize the roles of MR-1 [NiFe]-H(2)ase in these proposed reactions, the genes encoding both subunits of MR-1 [NiFe]-H(2)ase were cloned and then expressed in an MR-1 mutant without hyaB and hydA...

This paper offers a Latourian reading of T.C. Boyle’s novel When the Killing’s Done. It shows that satirizes contemporary ecological debates and stages cultural wars our current culture. also demonstrates, however, does not merely point out impasse ecologies: its fiction intuitively diagnoses “crisis purity” in modern environmental politics points us towards kind entangled ecologies sketched by...
