In a previous paper analytical equations were derived for the packing fraction of crystalline structures consisting of bimodal randomly placed hard spheres [H. J. H. Brouwers, Phys. Rev. E 76, 041304 (2007)]. The bimodal packing fraction was derived for the three crystalline cubic systems: viz., face-centered cubic, body-centered cubic, and simple cubic. These three equations appeared also to b...

We sharpen a classical result on the spectral asymptotics of the boundary value problems for self-adjoint ordinary differential operator. Using this result we obtain the exact L2-small ball asymptotics for a new class of zero mean Gaussian processes. This class includes, in particular, integrated generalized Slepian process, integrated centered Wiener process and integrated centered Brownian br...

Background: Rheumatoid arthritis is the most prevalent chronic rheumatologic disease of children. The quality of life (QOL) in these individuals is affected by physical pain, discomfort, treatment complications, and frequent absences from school leading to academic failure. No research similar to the present investigation was performed in this area. Aim: ...

We propose a novel approach for recognizing 3D CADmade objects in complex range images containing several overlapped and different objects. Objects are modeled by a graph whose nodes are surfaces and arcs are surface relations. We propose an object-centered graph model, called Visual Constraint graph (VC-graph), with special visual constraints modeling occlusions between object surfaces. The VC...

Self-assembly is a process in which small objects autonomously associate with each other to form larger complexes. It is ubiquitous in biological constructions at the cellular and molecular scale and has also been identified by nanoscientists as a fundamental method for building nano-scale structures. Recent years see convergent interest and efforts in studying self-assembly from mathematicians...

My research interests are concentrated in theoretical computer science, in particular in graph algorithms, approximation algorithms, complexity theory, and quantum computing. In the area of graph algorithms, my work is motivated by the increasing need to understand and manipulate massive graph structures that emerge from web applications and networks, using efficient graph approximation techniq...

Functional medicine is essentially patient centered, rather than disease centered. A structure is presented for uniting a patient-centered approach to diagnosis and treatment with the fruits of modern clinical science (which evolved primarily to serve the prevailing model of disease-centered care). The core scientific concepts of disease pathogenesis are antecedents, triggers, and mediators. An...

Human-centered computing has been described as " an emerging field that aims at bridging the existing gaps between the various disciplines involved with the design and implementation of computing systems that support people's activities " 1. Information visualization is certainly one of the disciplines in the center of human-centered computing 2. Or is it? Since we announced the Call for Paper ...
