We study the effect of spins on searches for gravitational waves from compact binary coalescences in realistic simulated early advanced LIGO data. construct a detection pipeline including matched filtering, signal-based vetoes, coincidence test between different detectors, and an estimate rate background events. restrict attention to neutron star--black hole (NS-BH) systems, we compare search using non-spinning templates one that include aligned with orbital angular momentum. To run...
Small-angle scattering studies on biological structures provide low-resolution models. More detailed models need a more elaborate analysis in order to show their uniqueness. The representation of small-angle both Cartesian coordinates and polar is discussed. degree non-uniqueness structural best presented terms multipole expansion. Contrast variation leads the evaluation basic functions Jc(κ), Jcs(κ) Js(κ), which add useful constraints model. experimental aspects this method X-ray neutron...
Collagen is the principal organic matrix in bone. The triple helical region of molecule 1014 amino acids long. In fibrils these molecules are staggered axially by integers 234 residues or 68 nm ( D ). This axial shift occurs self-assembly and can be understood terms a periodicity occurrence apolar polar acid sequence. Because molecular length L = 4.47 , there gaps 1.5 x 36.5 regularly arrayed throughout fibrils. three-dimensional arrangement quasi-hexagonal lattice with three distinct values...
Nuclear charge radii of $^{55,56}\mathrm{Ni}$ were measured by collinear laser spectroscopy. The obtained information completes the behavior at shell closure doubly magic nucleus $^{56}\mathrm{Ni}$. trend across closures in calcium and nickel is surprisingly similar despite fact that $^{56}\mathrm{Ni}$ core supposed to be much softer than $^{48}\mathrm{Ca}$ core. very low magnetic moment $\ensuremath{\mu}(^{55}\mathrm{Ni})=\ensuremath{-}1.108(20)\text{ }\text{ }{\ensuremath{\mu}}_{N}$...
This study evaluates the accuracy of computed modal frequencies and mode shapes obtained from a combined experimental/analytical model for simple beam structure. The structure was divided into two subsystems one subsystem tested to obtain its free-free modes. Using Component Mode Synthesis (CMS) technique, experimental data base directly coupled with finite element other create an total Both translational rotational elements residual flexibilities at interface were measured used in coupling....
Bunched-beam collinear laser spectroscopy is performed on neutron deficient $^{52,53}\mathrm{Fe}$ prepared through in-flight separation followed by a gas stopping. This novel scheme major step to reach nuclides far from the stability line in spectroscopy. Differential mean-square charge radii $\ensuremath{\delta}⟨{r}^{2}⟩$ of are determined relative stable $^{56}\mathrm{Fe}$ as $\ensuremath{\delta}⟨{r}^{2}{⟩}^{56,52}=\ensuremath{-}0.034(13)\text{ }\text{ }{\mathrm{fm}}^{2}$ and...
The small-angle scattering facility at Daresbury has been constructed for diffraction studies of a wide range naturally occurring and synthetic materials. high brightness the SRS is combined with focusing optics, resulting in exposure times that can be two or three orders magnitude less than those required on conventional source. Spacings 2000 Å vertical direction 300 horizontal observed, while resolution between 5000 600 Å. In addition, preliminary results have obtained double-crystal...
Charge radii of the unstable Ca36 and Ca38 nuclei were recently determined used to compute differences in charge between mirror ΔRch for Ca36−S36 Ca38−Ar38 pairs. Given correlation slope symmetry energy L at nuclear saturation density, we deduce L=5–70 MeV, which rules out a large fraction models that predict "stiff" equation state. This is most precise determination this model based on electromagnetic probes ground states. The range consistent with earlier analyses from both laboratory...
Solid-state (2)H NMR spectroscopy has been used to probe the dynamic disorder of hydroxyl deuterons in a synthetic sample deuterated hydroxyl-clinohumite (4Mg(2)SiO(4).Mg(OD)(2)), proposed model for incorporation water within Earth's mantle. Both static and magic angle spinning (MAS) methods were used. Static appears reveal little evidence process, yielding results similar those obtained from brucite (Mg(OD)(2)), where no dynamics on relevant timescale are expected be present. However, MAS...
We discuss the strategy for development of novel functional materials with tetragonal tungsten bronze structure. From starting composition Ba6GaNb9O30, effect A- and B-site substitutions on dielectric properties is used to develop an understanding origin stability dipolar response in these compounds. Both strain induced by large cations local variations created isovalent A-site enhance dipole but result a dilute, weakly correlated canonical relaxor behaviour. Decreasing cation size at...
Background: The systematic trend in mean-square charge radii as a function of proton or neutron number exhibits discontinuity at the nucleon-shell closures. While established $N=28$ shell closure is evident isotopic chains K through Mn, similar signature $N=20$ absent Ca region.Purpose: isotope shift between neutron-deficient $^{36}\mathrm{K}$ and $^{37}\mathrm{K}$ was determined to investigate change across chain.Methods: $D1$ atomic hyperfine spectra were measured using an optical pumping...
Abstract The roles of pH and ionic strength on the structure stability collagen fibrils have been investigated by means x‐ray neutron diffraction techniques. High‐angle shows that a salt concentration 0.5 M KCl is sufficient to reduce osmotic swelling related disordering in range 1–3. relative intensities low‐angle meridional Bragg reflections vary with pH. Difference Fourier syntheses between 7 1.6 data indicate, for both diffraction, reduced scattering contribution from telopeptides at low...
Previous studies of atmospheric pollution resulting from the 1963 eruption Mt. Agung have shown that volcanic dust caused temperature increases in lower stratosphere over Australia. The present study provides time series monthly-mean stratospheric temperatures for eight tropical stations on both sides equator. data been smoothed by taking 12-month running means. results suggest any effect may be impossible to isolate. Some features quasi-biennial oscillation zonal winds and are pointed out...
