Feasibility of T2 relaxation time in predicting the technical outcome of MR-guided high-intensity focused ultrasound treatment of uterine fibroids

International Journal of Hyperthermia, 2021
Purpose The aim of this study was to assess the feasibility of T2 relaxation time in predicting the immediate technical outcome i.e., nonperfused volume ratio (NPVr) of magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) treatment of ...

Relaxed Alternating Projection Methods [PDF]

SIAM Journal on Optimization, 2008
In this paper we deal with the von Neumann alternating projection method $x_{k+1}=P_{A}P_{B}x_{k}$ and with its generalization of the form $x_{k+1}=P_{A}(x_{k}+\lambda _{k}(P_{A}P_{B}x_{k}-x_{k}))$, where $A,B$ are closed and convex subsets of a Hilbert space $\mathcal{H}$ and $\operatorname{Fix}P_{A}P_{B}\neq \varnothing$.

APPLICATION OF PROGRESSIVE MUSCLE RELAXATION TO REDUCING THE ANXIETY OF HYPERTENSION CLIENTS

Nurse and Holistic Care, 2023
Background: Families with hypertension will cause anxiety or anxiety which can affect the stability of blood pressure. One of the managements of anxiety with psychotherapy methods is by doing progressive muscle relaxation therapy.

Applications of physical methods in high-frequency futures markets [PDF]

, 2007
In the present work we demonstrate the application of different physical methods to high-frequency or tick-by-tick financial time series data. In particular, we calculate the Hurst exponent and inverse statistics for the price time series taken from a ...

Measuring Residual Stresses with Crack Compliance Methods: An Ill-Posed Inverse Problem with a Closed-Form Kernel

Applied Mechanics
By means of relaxation methods, residual stresses can be obtained by introducing a progressive cut or a hole in a specimen and by measuring and elaborating the strains or displacements that are consequently produced.

Frequency Dependent Rheology of Vesicular Rhyolite [PDF]

, 1993
Frequency dependent rheology of magmas may result from the presence of inclusions (bubbles, crystals) in the melt and/or from viscoelastic behavior of the melt itself.

CONVERGENCE OF THE RELAXED NEWTON'S METHOD [PDF]

Journal of the Korean Mathematical Society, 2014
In this work we study the local and semilocal convergence of the relaxed Newton's method, that is Newton's method with a relaxation parameter 0 < λ < 2. We give a Kantorovich-like theorem that can be applied for operators defined between two Banach spaces.

Pore surface exploration by NMR [PDF]

, 2003
A carefully chosen set of experimental techniques applied to porous media characterization provides results that can be much greater than the sum of the individual parts.
