Vesicle Shapes and Shape Transformations: A Systematic Study [PDF]
, 1991 In our contribution we report a systematic experimental and theoretical study on shape transformations. In order to avoid the above mentioned complications we have investigated vesicles which consist of electrically neutral lipids (that is phosphatidylcholine) in Millipore water.

Microfabrication Using Shape‐Transforming Soft Materials [PDF]
Advanced Functional Materials, 2020 AbstractThe fabrication of hollow and multicomponent micro‐objects with complex inner structures using state‐of‐the‐art subtractive, formative, and additive manufacturing technologies is challenging. Controlled shape transformation offers a very elegant solution to this challenge.

Identifying shape transformations from photographs of real objects. [PDF]
PLoS ONE, 2018 An important task of human visual cognition is to make inferences about properties of objects. One such property is an object's causal history: what happened to the object in its past (e.g., "this paper has been folded").

Mapping of shape invariant potentials by the point canonical transformation [PDF]
, 2007 In this paper by using the method of point canonical transformation we find that the Coulomb and Kratzer potentials can be mapped to the Morse potential.

The Darboux transformation and algebraic deformations of shape-invariant potentials [PDF]
, 2003 We investigate the backward Darboux transformations (addition of a lowest bound state) of shape-invariant potentials on the line, and classify the subclass of algebraic deformations, those for which the potential and the bound states are simple ...

Exceptional orthogonal polynomials and the Darboux transformation [PDF]
, 2010 We adapt the notion of the Darboux transformation to the context of polynomial Sturm-Liouville problems. As an application, we characterize the recently described $X_m$ Laguerre polynomials in terms of an isospectral Darboux transformation.

Momentum distribution of a freely expanding Lieb-Liniger gas [PDF]
, 2009 We numerically study free expansion of a few Lieb-Liniger bosons, which are initially in the ground state of an infinitely deep hard-wall trap. Numerical calculation is carried out by employing a standard Fourier transform, as follows from the Fermi-Bose

Shape invariance through Crum transformation
, 2006 We show in a rigorous way that Crum's result on equal eigenvalue spectrum of Sturm-Liouville problems can be obtained iteratively by successive Darboux transformations. It can be shown that all neighbouring Darboux-transformed potentials of higher order,
