P.03 Local Pulse Wave Velocity Estimation using a Double Gaussian Propagation Model

open access: goldArtery Research, 2020
Background: Pulse wave velocity (PWV) is an established marker of arterial stiffness [1]. Local PWV estimates, however, are affected by confluence of incident and reflected waves, biasing the spatiotemporal propagation of the systolic foot (SF) in the ...

FT-IR Spectroscopic Studies and Gaussian 03 Calculations of 2, 2'-Ethylenebis(nitrilomethylidene)diphenol [PDF]

open access: bronzeOriental Journal Of Chemistry, 2012
The vibrational wavenumbers and corresponding vibrational assignments of 2,2'-Ethylene bis(nitrilomethylidene) diphenol are examined theoretically using the Gaussian03 set of quantum chemistry codes. Comparison of the observed IR spectra with the calculated results by HartreeFock and B 3 lyp method is found in agreement with the experimental data ...

Rigid and Relaxed Potential Energy Surface Scans (PES Scan) in Gaussian 03 and Gaussian 09

open access: gold, 2010
Another common question on CCL… The use of Internal Redundant coordinates (through the Opt=ModRedundant option) must not be overlooked! This option performes a geometry optimization at each step while maintaining the scanned variable constant, which is referred to as a Relaxed Potential Energy Surface (PES) Scan.

Constraints on Primordial Non‐Gaussianity from the High‐Redshift Cluster MS 1054−03 [PDF]

open access: bronzeThe Astrophysical Journal, 2000
The implications of the massive, X-ray selected cluster of galaxies MS1054--03 at $z=0.83$ are discussed in light of the hypothesis that the primordial density fluctuations may be nongaussian. We generalize the Press-Schechter (PS) formalism to the nongaussian case, and calculate the likelihood that a cluster as massive as MS1054 would appear in the ...

Utilization of Molecular Simulation Software Gaussian 03 to Design Absorbent for CO2 Capture

open access: diamondProcedia Engineering, 2011
AbstractA preliminary study on the interaction between molecules of absorbent for CO2 absorption was undertaken using Gaussian 03 molecular simulation software. The results indicate that the molecular interaction energy has strong correlations with Henry's constant.

Analyzing Natural Bond Orbitals (NBO) results from Gaussian '03 & '09

open access: gold, 2009
I'm posting this white paper "as is" but I will keep on coming back to update it; the thing is that I haven't had the time to post anything else lately and if I don't do it like this then I will never get it out. Please be kind on your comments and ratings! For a more thorough discussion of NBO analysis please check out the references.

Efd-C(13)03/44 Bayesian Tomography Of Soft X-Ray And Bolometer Systems Using Gaussian Processes

open access: green, 2013
A new Bayesian tomographic method for soft-X and bolometer diagnostic systems has been developed. The method is non-parametric in the sense of using Gaussian processes to model ,the underlying emissivity distribution, and the regularization of such a model becomes defined by a multivariate normal distribution at the points where the emissivity ...

Is $$d^*(2380)$$ d ∗ ( 2380 ) a compact hexaquark state?

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The most fascinating dibaryon in the non-strange quark sector is $$d^*(2380)$$ d ∗ ( 2380 ) , which was reported by WASA-at-COSY Collaboration and confirmed by A2@MAMI Collaboration. The reported mass and decay width are $$M\approx 2.37$$ M ≈ 2.37 GeV, $$
