Influence of Age and Central Hypertension on the Form Factor Needed to Estimate Mean Aortic Pressure, and Its Implications for Pulse Pressure Amplification: A Secondary Data Analysis [PDF]
Journal of the American Heart Association: Cardiovascular and Cerebrovascular DiseaseBackground Mean aortic pressure (MAP) plays a pivotal role in both cardiovascular dynamics and the noninvasive estimation of systolic aortic pressure. MAP can be estimated by adding a fraction of the pulse pressure (PP) to the diastolic aortic pressure ...

Spectral Form Factor and Dynamical Localization [PDF]
Entropy, 2023 Quantum dynamical localization occurs when quantum interference stops the diffusion of wave packets in momentum space. The expectation is that dynamical localization will occur when the typical transport time of the momentum diffusion is greater than the

Dispersive analysis of the pion transition form factor [PDF]
Eur Phys J C Part Fields, 2014 We analyze the pion transition form factor using dispersion theory. We calculate the singly-virtual form factor in the time-like region based on data for the e+e−→3π cross section, generalizing previous studies on ω,ϕ→3π decays and γπ→ππ scattering, and ...

Square form factorization [PDF]
Mathematics of Computation, 2007 We present a detailed analysis of SQUFOF, Daniel Shanks’ Square Form Factorization algorithm. We give the average time and space requirements for SQUFOF. We analyze the effect of multipliers, either used for a single factorization or when racing the algorithm in parallel.

helicity form factors and the decays * [PDF]
Chinese Physics C, 2022 Abstract In this paper, we calculate the helicity form factors (HFFs) up to twist-4 accuracy by using the light-cone sum rules (LCSR) approach. After extrapolating those HFFs to the physically allowable

Exact form-factor results for the longitudinal structure factor of the massless XXZ model in zero field [PDF]
, 2012 We consider the XXZ quantum spin chain in its massless, disordered regime at zero field. We derive an exact expression for the two-spinon form-factor of Sz = 1/2σz by taking a limit of the massive XYZ form-factors found by Lashkevich and by Lukyanov and ...

Study of positive parity states form factors for 17O nucleus with Skyrme-Hartree-Fock method [PDF]
Kirkuk Journal of Science, 2023 Elastic and inelastic electron scattering form factors for the 17O nucleus are calculated for the positive parity low-lying states in the momentum transfer interval 0.05-3 fm in the framework of shell model and Skyrme-Hartree-Fock calculations.

On the form factor for the unitary group [PDF]
Journal of Mathematical Physics, 2004 We study the combinatorics of the contributions to the form factor of the group U(N) in the large N limit. This relates to questions about semiclassical contributions to the form factor of quantum systems described by the unitary ensemble.
