Eculizumab is a humanized monoclonal antibody that targets complement protein C5 and inhibits terminal complement-mediated hemolysis associated with paroxysmal nocturnal hemoglobinuria (PNH). The molecular basis for the poor response to eculizumab in small population of Japanese patients unclear.We assessed sequences gene encoding PNH who had either good or eculizumab. We also evaluated functional properties as it was encoded these patients.Of 345 received eculizumab, 11 response. All single...
A new boundary element method (BEM) is developed for three-dimensional analysis of fiber-reinforced composites based on a rigid-inclusion model. Elasticity equations are solved in an elastic domain containing inclusions which can be assumed much stiffer than the host medium. Therefore treated as rigid ones with only six rigid-body displacements. It shown that integral equation (BIE) this case simplified and weakly-singular displacement kernel present. The BEM accelerated fast multipole used...
Fast multipole methods (FMM) are a fundamental operation for the simulation of many physical problems. The high-performance design such usually requires to carefully tune algorithm both targeted physics and hardware. In this paper, we propose new approach that achieves high performance across architectures. Our method consists expressing FMM as task flow employing state-of-the-art runtime system, StarPU, process tasks on different computing units. We flow, mathematical operators, their...
We have been investigating applications of a topology optimisation method with the level set method. In this study, to further enhance applicability method, we investigate for three-dimensional scalar wave scattering problems which can be defined in an unbounded domain. To end, fast multipole boundary element (FMBEM), deal domain accurately and efficiently, is implemented proposed A detail algorithm FMBEM presented. Also, rigorous derivation topological derivative, characterises sensitivity...
Abstract Recently, the application of graphics processing units (GPUs) to scientific computations is attracting a great deal attention, because GPUs are getting faster and more programmable. In particular, NVIDIA's called compute unified device architecture enable highly mutlithreaded parallel computing for non‐graphic applications. This paper proposes novel way accelerate boundary element method (BEM) three‐dimensional Helmholtz' equation using CUDA. Adopting techniques data caching...
Summary High performance fast multipole method is crucial for the numerical simulation of many physical problems. In a previous study, we have shown that task‐based provides flexibility required to process wide spectrum particle distributions efficiently on multicore architectures. this paper, now show how such an approach can be extended fully exploit heterogeneous platforms. For that, design highly tuned graphics processing unit (GPU) versions two dominant operators P2P and M2L) as well...
It is well known that the solution of an exterior acoustic problem governed by Helmholtz equation violated at eigenfrequencies associated interior when boundary element method (BEM) based on conventional integral (CBIE) applied without any special treatment to solve it. To tackle this problem, Burton-Miller formulation using a linear combination CBIE and its normal derivative (NDBIE) emerges as effective efficient formula which proved yield unique for all frequencies if imaginary part...
Studies of interactive systems in museums have raised important design considerations, but so far failed to address sufficiently the particularities family interaction and co-operation. This paper introduces qualitative video-based observations Japanese families using an portable guide system a museum. Results show how unexpected usage can occur through between members. The highlights necessity more fully consider familial relationships HCI.
This paper presents a new method for rendering views, especially those of large-scale scenes, such as broad city landscapes. The main contribution our is that we are able to easily render any view from an arbitrary point direction on the ground in virtual environment. Our belongs family work employs plenoptic functions; however, unlike other works this type, particular allows us novel almost plane at which images taken. Previous methods, hand, have some restraints concerning their...

The FMM is class methods compute pairwise interactions between N particles for given error tolerance and with computational cost . described in are applicable any FMMs which multipole‐to‐local (M2L) operator dense matrix precomputed. case example black‐box (bbFMM), variant that can handle large kernels....
This paper presents a fast multipole boundary element approach to the 3D acoustic shape sensitivity analysis based on discrete adjoint variable method. The Burton–Miller formula is used conquer fictitious eigenfrequency problem of original integral equation method in solving exterior problems. Constant elements are discretize boundary, so that hypersingular integrals contained formulae can be evaluated explicitly and directly. Numerical examples presented demonstrate accuracy efficiency...
