In silico, cell based approaches for modeling biological morphogenesis are used to test and validate our understanding of the mechanical processes that at work during growth organization multi-cell tissues. As compared in vivo experiments, computer frameworks dedicated tissue allow us easily different hypotheses, quantify impact various biophysically relevant parameters. Here, we propose a form...

A genetic algorithm was used to evolve bat-like pinna shapes for a biomimetic sonarhead. Pinnae model consisted of small reeectors placed around the transducer. Experiments with ten reeectors showed the problem of phase cancellation in the received echoes. Analysis of phase cancellation suggests more realistic pinna models for future developments .

This paper presents work-in-progress on SQUIDS, a system for the interactive creation and deformation of superquadric shapes in virtual environments. SQUIDS is one component of a prototype system for semi-automatically creating realistic virtual environments, based on image data captured from real-world scenes.

A genetic algorithm was used to evolve bat-like pinna shapes for a biomimetic sonarhead. Pinnae model consisted of small re ectors placed around the transducer. Experiments with ten re ectors showed the problem of phase cancellation in the received echoes. Analysis of phase cancellation suggests more realistic pinna models for future developments.

This paper addresses interactive function-based shape modeling where relatively small formulas are used rather than thousands of polygons. Interactive modification of the function model with concurrent visualization of the respective polygonal mesh lets us provide both the interactivity and any required level of detail leading to photo-realistic appearance of the resulting shapes. We have propo...

Let the sign of a standard Young tableau (SYT) be permutation obtained by reading entries row from left to right, starting top row. By sign-reversing involution on tableaux in terms lattice paths, we obtain sign-balance $n$-cell SYTs all shapes with at most three rows. For skew shapes, partial results enumeration $2n$-cell rows, under parity condition part.

introduction:  electroporation  is  a  technique  for  increasing  the  permeability  of  the  cell  membrane  to  otherwise  non-permeate  molecules  due  to  an  external  electric  field.  this  permeability  enhancement  is  detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the  pulse  strength  threshold.  in  this  study,  the  variabil...

Human B-cells play an important role in the immune system, and because of their relatively simple structures with a nearly spherically shaped cell membrane and a large nucleus, they provide a good case to study on how the details of cell structure affect light scattering properties. A finite-difference-time-domain (FDTD) method is used to calculate angleresolved light scattering distributions f...
