The Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO)

, 2011
The Atmospheric Imaging Assembly (AIA) provides multiple simultaneous high-resolution full-disk images of the corona and transition region up to 0.5 R⊙ above the solar limb with 1.5-arcsec spatial resolution and 12-second temporal resolution.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Interactive effects of elevated atmospheric CO2 and UV-B radiation: A multi-level study on marine diatom Skeletonema pseudocostatum

Ecotoxicology and Environmental Safety
Climate change as a result of increases in greenhouse gas emissions, such as CO2, is causing significant alteration in global environmental conditions, including ocean acidification (OA).

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Wood-based Businesses and the Economic Development of Europe in the Nineteenth and Twentieth Centuries – An Introduction

Jahrbuch für Wirtschaftsgeschichte
This introduction sketches out what relevance wood and wood products have had in Europe’s industrial societies. It also summarizes some peculiarities of the wood-based businesses caused by both the materiality of wood and the ecologies of forests.

Tension gastrothorax in late diagnosis of congenital diaphragmatic hernia

Radiology Case Reports
Tension gastrothorax is a rare but potentially fatal complication of congenital diaphragmatic hernia, frequently mistaken for tension pneumothorax. Early recognition is essential to avoid delays in definitive management.

The Reaction $\pi N \to \pi \pi N$ at Threshold

, 1994
We consider the chiral expansion for the reaction $\pi N \to \pi \pi N$ in heavy baryon chiral perturbation theory. To order $M_\pi$ we derive novel low--energy theorems that compare favorably with recent determinations of the total cross sections for ...

Embeddings for Non-Critical Superstrings [PDF]

, 1994
It was previously shown that at critical central charge, $N$-extended superstrings can be embedded in $(N+1)$-extended superstrings. In other words, $(N=0,c=26)\to (N=1,c=15)\to (N=2,c=6)\to (N=3,c=0) \to (N=4,c=0) $.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Geographical Aspects of Diphtheria in England and Wales: Immunisation and the Spatial Sequence of Retreat to Effective Elimination, 1921 to 1964

Jahrbuch für Wirtschaftsgeschichte
On the eve of the Second World War, an average of 5,000 hospital beds in England and Wales were occupied at any one time by diphtheria patients, and the annual costs of their treatment was £1 million.
