Lamellar Level Correlations Between Mechanical Behavior and Composition in Mouse Bone
No full textWe studied the lamellar level correlations between the local composition and local mechanical properties in the femur of two inbred strains of mice (A/J and C57BL/6J (B6)), with known differences in the average mineralization and long-bone mechanical properties, to gain insights into how their extracellular matrix is mineralized. The local elastic moduli and indentation yield strengths were determined using spherical nanoindentation stress-strain analysis, while Raman spectroscopy was used to determine the local composition around the indents in a total of 11 samples. Our results show a significant difference in the mineral-to-matrix ratio of the two strains of mice, with the A/J mice showing an overall higher mineral-to-matrix ratio and lower carbonate substitution in the mineral. These differences are prominent in the newer bone and become less significant as the bone matures. Additionally, local mineral-to-matrix ratio was found to be a good indicator of the local mechanical properties.This is a manuscript of the article Published as Vachhani, Shraddha J., Surya R.

Direct Measurement of the Branching Fractions B (ψ (3686) →j /ψX) and B (ψ (3770) →j /ψX), and Observation of the State R (3760) in e+e- →j /ψ X
No full textWe report a measurement of the observed cross sections of e+e-→J/ψX based on 3.21 fb-1 of data accumulated at energies from 3.645 to 3.891 GeV with the BESIII detector operated at the BEPCII collider. In analysis of the cross sections, we measured the decay branching fractions of B(ψ(3686)→J/ψX)=(64.4±0.6±1.6)% and B(ψ(3770)→J/ψX)=(0.5±0.2±0.1)% for the first time. The energy-dependent line shape of these cross sections cannot be well described by two Breit-Wigner (BW) amplitudes of the expected decays ψ(3686)→J/ψX and ψ(3770)→J/ψX. Instead, it can be better described with one more BW amplitude of the decay R(3760)→J/ψX. Under this assumption, we extracted the R(3760) mass MR(3760)=3766.2±3.8±0.4 MeV/c2, total width ΓR(3760)tot=22.2±5.9±1.4 MeV, and product of leptonic width and decay branching fraction ΓR(3760)eeB[R(3760)→J/ψX]=(79.4±85.5±11.7) eV. The significance of the R(3760) is 5.3σ. The first uncertainties of these measured quantities are from fits to the cross sections and second systematic
Methods for Efficiently Computing the MoM Impedance Matrix for APEx Type Basis Functions
No full textAlternative methods for efficiently computing the elements of the impedance matrix arising in the method-of-moments (MoM) based asymptotic phasefront extraction (APEx) method are presented. In APEx, the number of unknowns can be drastically reduced by making use of the phasefront characteristics of the local currents at smooth parts of the scatterer obtained at a lower frequency. At the high frequency of interest, the scaled basis functions are in the form of linearly phased constant amplitude currents or traveling waves (TWs) defined on supports that are significantly larger than the ones for the conventional MoM. The standard way of computing the mutual coupling impedance between these TW basis/test functions requires a 4-fold numerical surface integration on the supports (or patches) that typically are a few wavelengths long over a single dimension. Specifically, three different methods are investigated to efficiently and accurately compute the mutual coupling impedance. The advantages and disadvantages as well as the range of applicability of each method are discussed. Accuracy and CPU time comparisons are provide
Probiotics in Diverticular Disease of the Colon: an Open Label Study
No full textAim: To investigate the effectiveness and safety of a symbiotic mixture in preventing recurrence of constipation-related abdominal pain in patients with uncomplicated diverticular disease of the colon.
Methods: Forty-six consecutive patients (10 men, 36 women, mean age 62.5 years, range 49 to 77 years), previously affected by symptomatic uncomplicated diverticular disease of the colon, were enrolled in a 6-month follow-up study in a prospective, randomized, open-label study. The following symptoms were assessed at entry and through follow-up by using a quantitative scale: constipation, diarrhoea and abdominal pain. After recruitment, the patients were assigned to the following treatment: SCM-III symbiotic mixture, 10ml three times a day. The colonization of ingested Lactobacillus acidophilus 145 and Bifidobacterium spp. 420 was assessed by specie-specific PCR. Forty-five patients completed the study (97%).
Results: Thirty-one patients (68%) were still symptom free after the 6th month of treatment. Treatment with SCM-III was regarded as "effective" or "very effective" in more than 78% of the patients altogether (p<0.01 vs baseline values). The microbiological study showed that, as compared to baseline values, SCM-III enabled a significant increase of the lactobacilli and bifidobacteria counting and a trend decrease of clostridia. Genomic analysis confirmed the survivability of the ingested strain as long as treatment was given.
Conclusions: The present symbiotic mixture seems to be effective in preventing recurrence of symptomatic uncomplicated diverticular disease of the colon, especially in those patients with constipation-predominant features
