This paper describes an efficient random walk particle tracking (RWPT) method for finite element models in two dimensions. The method for interpolation of global node based velocities for unstructured grids and the implementation of the RWPT are described. The RWPT method is verified using published results of particle path lines to verify the calculation of the velocity field. RWPT transport r...

Nanoporous silicon is known to have a thermal conductivity that is orders of magnitude smaller than the bulk crystalline silicon from which it is formed. Even though the strong columnar microscopic structure of porous silicon indicates the possibility of highly anisotropic thermal properties, there have been no measurements. We report here an experimental investigation of this anisotropy. An an...

Historically, hexahedral finite element mesh generation has required significant geometric decomposition with the resulting consequence that generating hexahedral meshes can be extremely difficult to perform and automate and the process often takes several orders of magnitude longer in time to complete than current methods for generating tetrahedral meshes. In this work, we present methods for ...

This taxonomic differentiation of Lls is not superfluous, since structural differences exist between Lls from different taxonomic orders, and significant differences may even exist between Lls found in different genera wit...

The paper submitted deals with the investigation of failures of engineering structures by means of the Method of higher orders spectra. The reason why Method of higher orders spectra is prospective in future is that unlike other non-destructive methods this one offers a high-quality information on the existence of non-linear processes in material and geometrically complex investigated samples (...

The decay rate of neutrinoless double beta (0νββ) decay contains terms from heavy particle exchange, which lead to dimension-9 (d = 9) six fermion operators at low energies. Limits on the coefficients of these operators have been derived previously neglecting the running of the operators between the high-scale, where they are generated, and the energy scale of double beta decay, where they are ...

Inclusive B-meson decays, such as semileptonic B → Xulν̄ decays and penguininduced B → Xsγ decays, are of special interest because they are sensitive probes of electroweak parameters as well as new physics. Especially for the precise determination of the CKM matrix element |Vub|, the region near the kinematic endpoint for the lepton energy spectrum, El ∼ E max l = mB/2, in the decay B → Xulν̄ pla...

We report the implementation of a micro-patterned, glass-based photonic sensing element that is capable of label-free biosensing. The diffractive optical analyzer is based on the differential response of diffracted orders to bulk as well as surface refractive index changes. The differential read-out suppresses signal drifts and enables time-resolved determination of refractive index changes in ...

Electronic Health Records (EHRs) have increased the utility and portability of health information by storing it in structured formats. However, EHRs separate this structured data from the rich, free-text descriptions of clinical notes. The ultimate objective of our research is to develop an interactive progress note that unifies entry, access, and retrieval of structured and unstructured health...

We report a method to generate phase-only diffractive beam splitters allowing asymmetry of the target diffracted orders, as well as providing a tailored phase difference between the diffracted orders. We apply a well-established design method that requires the determination of a set of numerical parameters, and avoids the use of image iterative algorithms. As a result, a phase lookup table is d...
