[Device for determining the elastic properties of the internal organs and vessels].

Arkhiv anatomii, gistologii i embriologii

Dobrovol'skiĭ GA, Paniutina TN.
PMID: 907491
Arkh Anat Gistol Embriol. 1977 Aug;73(8):92-5.

Apparatuses to study elastic properties of organs and vessels in small laboratory animals, human fetuses and infants were suggested in the work. Their advantage in comparison with the existing ones is a combination of a highly sensitive intensity measuring...

Sensible human projects: haptic modeling and surgical simulation based on measurements of practical patients with MR elastography--measurement of elastic modulus.

Studies in health technology and informatics

Suga M, Matsuda T, Okamoto J, Takizawa O, Oshiro O, Minato K, Tsutsumi S, Nagata I, Sakai N, Takahashi T.
PMID: 10977567
Stud Health Technol Inform. 2000;70:334-40.

To provide realistic surgical simulation, 3D visualization and haptic feedback are important. In the existing surgical simulators, the fidelity of the deformation and haptic feedback is limited because they are based on the subjective evaluation of the expert-user and...

Correlation between the static and dynamic stiffness indices of medical elastic compression stockings.

Dermatologic surgery : official publication for American Society for Dermatologic Surgery [et al.]

van der Wegen-Franken K, Tank B, Neumann M.
PMID: 18798754
Dermatol Surg. 2008 Nov;34(11):1477-85. doi: 10.1111/j.1524-4725.2008.34312.x. Epub 2008 Sep 15.

BACKGROUND: Compression therapy with medical elastic compression stockings (MECS) has been used effectively for treating patients with chronic venous insufficiency for many years.OBJECTIVE: To study the correlation between static stiffness and the dynamic stiffness index of 18 different brands...

Quantifying elasticity analysis: how external effectors cause changes to metabolic systems.

Bio Systems

Ainscow EK, Brand MD.
PMID: 10203195
Biosystems. 1999 Feb;49(2):151-9. doi: 10.1016/s0303-2647(98)00040-9.

The sites of action of external effectors, such as inhibitors or hormones, on metabolic systems can be described qualitatively by elasticity analysis, or quantitatively by regulation analysis. The use of the latter approach has been limited, due to its...

A Lagrangian meshfree method applied to linear and nonlinear elasticity.

PloS one

Walker WA.
PMID: 29045443
PLoS One. 2017 Oct 18;12(10):e0186345. doi: 10.1371/journal.pone.0186345. eCollection 2017.

The repeated replacement method (RRM) is a Lagrangian meshfree method which we have previously applied to the Euler equations for compressible fluid flow. In this paper we present new enhancements to RRM, and we apply the enhanced method to...

Robust determination of Young's modulus of individual carbon nanotubes by quasi-static interaction with Lorentz forces.

Ultramicroscopy

Löffler M, Weissker U, Mühl T, Gemming T, Büchner B.
PMID: 21185460
Ultramicroscopy. 2011 Jan;111(2):155-8. doi: 10.1016/j.ultramic.2010.10.019. Epub 2010 Nov 07.

Young's modulus of an individual multi-wall carbon nanotube has been determined by the method of quasi-static transverse bending due to a Lorentz force observed in situ in a transmission electron microscope. The deflection of the nanotube allows the determination...

Development of a 3D visualization system for surgical field deformation with geometric pattern projection.

Studies in health technology and informatics

Hayashibe M, Suzuki N, Kobayashi S, Nakata N, Hattori A, Nakamura Y.
PMID: 15718722
Stud Health Technol Inform. 2005;111:172-7.

Intra-operative navigation in which the target position is provided to assist an intuitive understanding of the surgical field has been studied and applied in many clinical areas. Position measurement of a surgical field is usually performed with a magnetic...

Phase diagrams and morphological evolution in wrapping of rod-shaped elastic nanoparticles by cell membrane: a two-dimensional study.

Physical review. E, Statistical, nonlinear, and soft matter physics

Yi X, Gao H.
PMID: 25019819
Phys Rev E Stat Nonlin Soft Matter Phys. 2014 Jun;89(6):062712. doi: 10.1103/PhysRevE.89.062712. Epub 2014 Jun 24.

A fundamental understanding of cell-nanomaterial interaction is essential for biomedical diagnostics, therapeutics, and nanotoxicity. Here, we perform a theoretical analysis to investigate the phase diagram and morphological evolution of an elastic rod-shaped nanoparticle wrapped by a lipid membrane in...

Confined disclinations: exterior versus material constraints in developable thin elastic sheets.

Physical review. E, Statistical, nonlinear, and soft matter physics

Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Feb;91(2):022404. doi: 10.1103/PhysRevE.91.022404. Epub 2015 Feb 09.

We examine the shape change of a thin disk with an inserted wedge of material when it is pushed against a plane, using analytical, numerical, and experimental methods. Such sheets occur in packaging, surgery, and nanotechnology. We approximate the...

Much of our understanding of vibrational excitations and elasticity is based upon analysis of frames consisting of sites connected by bonds occupied by central-force springs, the stability of which depends on the average number of neighbors per site z....
