Dyadic junctional couplings between cardiac sarcoplasmic reticulum (SR) and plasma membrane presumably are implicated in release of Ca2+ from terminal cisterns of SR during excitation-contraction coupling. We measured the areas of SR and plasma membrane involved in such couplings in late embryonic and neonatal rabbit left ventricles during a developmental period characterized by rapid cell grow...
Water introduced to surface drainages, such as agricultural and roadway runoff, mine drainage, or coalbed natural gas (CBNG)-produced water, potentially can be of environmental concern. In order to mitigate potential environmental effects, it may be important to be able to trace water discharged to the surface as it infiltrates and interacts with near-surface aquifers. We have chosen to study w...
In this work, we applied advanced Synchrotron Radiation (SR) induced techniques to the study of the chemisorption of the Self Assembling Peptide EAbuK16, i.e., H-Abu-Glu-Abu-Glu-Abu-Lys-Abu-Lys-Abu-Glu-Abu-Glu-Abu-Lys-Abu-Lys-NH₂ that is able to spontaneously aggregate in anti-parallel β-sheet conformation, onto annealed Ti25Nb10Zr alloy surfaces. This synthetic amphiphilic oligopeptide is a go...
New calcite Sr/Sr data for 47 limestones from the metamorphosed and deformed Neoproterozoic–Cambrian Dalradian Supergroup of Scotland and Ireland are used to identify secular trends in seawater Sr/Sr through the Dalradian succession and to constrain its depositional age. Dalradian limestones commonly have Sr .1000 ppm, indicating primary aragonite and marine diagenesis. Low Mn, Mn/Sr ,0.6, O an...
X-ray experiments are very frequently detector limited at today’s storage ring synchrotron radiation (SR) sources, and will be even more so at future Energy Recovery Linac and X-ray Free Electron Laser sources. Image plate and phosphor-coupled CCD detectors that predominate at present-day sources were outgrowths of technologies initially developed for the medical and astronomical communities, r...
What happens to ferromagnetism at the surfaces and interfaces of manganites? With the competition between charge, spin, and orbital degrees of freedom, it is not surprising that the surface behaviour may be profoundly different to that of the bulk. Using a powerful combination of two surface probes, tunnelling and polarized x-ray interactions, this paper reviews our work on the nature of the el...
Many proteins retained within the endo/sarcoplasmic reticulum (ER/SR) lumen express the COOH-terminal tetrapeptide KDEL, by which they continuously recycle from the Golgi complex; however, others do not express the KDEL retrieval signal. Among the latter is calsequestrin (CSQ), the major Ca2+-binding protein condensed within both the terminal cisternae of striated muscle SR and the ER vacuolar ...
Interphase chromatin is arranged into topologically separated domains comprising gene expression and replication units through genomic sequence elements, so-called MAR or SAR regions (for matrix- or scaffold-associating regions). S/MAR regions are located near the boundaries of actively transcribed genes and were shown to influence their activity. We show that scaffold attachment factor B (SAF-...
Recently deconvolution-based methods, like the DAMAS, have greatly improved spatial resolutions of the Beamforming in aeroacoustic imaging. But most of existing methods are not robust to background noise. In this paper, we propose two robust superresolution approaches using Sparsity Constraint (SC-RDAMAS) and Sparse Regularisation (SR-RDAMAS) respectively to simultaneously estimate source power...
Galaxy source counts in the infrared provide strong constraints on the evolution of the bolometric energy output from distant galaxy populations. We present the results from deep 24 m imaging from Spitzer surveys, which include 5 ;10 sources to an 80% completeness of ’60 Jy. The 24 m counts rapidly rise at near-Euclidean rates down to 5 mJy, increase with a super-Euclidean rate between 0.4 and ...
