Search for Turbulent Gas through Interstellar Scintillation [PDF]
, 2011 Stars twinkle because their light propagates through the atmosphere. The same phenomenon is expected when the light of remote stars crosses a Galactic - disk or halo - refractive medium such as a molecular cloud.We present the promising results of a test

Irish Mathematical Society Bulletin, 1988 Crossed modules provide a very useful tool in algebraic topology, algebraic K-theory, group cohomology and combinatorial group theory. They were introduced almost 40 years ago by J. H. C. Whitehead in his work on combinatorial homotopy theory. Given this illustrious start and their proven potential, it is strange that they are not very well known to ...

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

CeROArt : Conservation, Exposition, Restauration d'Objets d'Art, 2011 The comparative study of several big wooden crosses painted by Giotto allowed to deepen the work organization in the Middle Ages’ workshop. This analysis found several analogies of execution between the works, by demonstrating that the production of ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10
FEBS Letters, EarlyView.Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Characteristics and Behavior of Guineafowl and Domesticated Chicken Hybrids [PDF]
, 1976 The description, behavior, and morphologic measurements are presented for two hybrid crosses of domesticated chicken and guineafowl. The ease at which gallinaceous birds hybridize might warrant a closer look at the classification system.

Magnification relations of quad lenses and applications on Einstein crosses
, 2016 In this work, we mainly study the magnification relations of quad lens models for cusp, fold and cross configurations. By dividing and ray-tracing in different image regions, we numerically derive the positions and magnifications of the four images for a

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A new intergeneric hybrid: xGastonialoe 'Gordon Rowley' [PDF]
, 2017 A new intergeneric hybrid genus xGastonialoe is named for crosses with the parentage Gasteria x Gonialoe (Aloe). An attractive cultivar in this new nothogenus is named xGastonialoe 'Gordon Rowley', in honour of an ardent champion of such ...
