Spherical harmonics (SH) were used to approximate the volume and three-dimensional geometry of multiple sclerosis (MS) lesions in deceased patients. The institutional ethical committee does not require its approval for studies involving pathologic specimens. Pathologic findings were used as the reference standard. In addition, lesion volume was measured with cylindrical approximation (CA). Volu...

Dithiothreitol (DTT)-based displacement is widely utilized for separating ligands from their gold nanoparticle (AuNP) conjugates, a critical step for differentiating and quantifying surface-bound functional ligands and therefore the effective surface density of these species on nanoparticle-based therapeutics and other functional constructs. The underlying assumption is that DTT is smaller and ...

We consider settings providing the existence of stable two-dimensional (2D) dissipative solitons with zero and nonzero vorticity in optical media quadratic ($\chi^{(2)}$) nonlinearity. To compensate spatially uniform loss both fundamental-frequency (FF) second-harmonic (SH) components system, a strongly localized amplifying region ("hot spot",HS), carrying linear gain, is included, acting onto ...

The antigenic relationship between human neuronal and lymphocyte cell surface antigens has been analyzed using heteroantisera raised against human peripheral blood mononuclear cells (PBMC). The specificities of the crossreactive antigens were examined by immunoprecipitation of 125I-labeled SK-N-SH cultured neuronal cells using rabbit anti-PBMC (RAPBMC) sera and compared to known specificities u...

Abstract In this paper, the geometrical effects of shallow twin lined tunnels with different cross sections are investigated to obtain anti-plane seismic ground motion under vertical/horizontal incident plane SH waves. A model long two-dimensional is established and embedded in a homogeneous linear elastic half-plane by an applied numerical time-domain boundary element approach. addition brief ...

A spherical antenna array (SAA) is an array-designed arrangement capable of scanning in almost all the radiation sphere with constant directivity. It finds recent applications aerospace, spacecraft, vehicular and satellite communications. Therefore, estimation direction-of-arrival (DoA) electromagnetic (EM) waves that impinge on SAA unknown mutual coupling called for research attention. This pa...

Detection and quantification of cell viability and growth in two-dimensional (2D) and three-dimensional (3D) cell cultures commonly involve harvesting of cells and therefore requires a parallel set-up of several replicates for time-lapse or dose-response studies. Thus, developing a non-invasive and touch-free detection of cell growth in longitudinal studies of 3D tumor spheroid cultures or of s...

Three-dimensional (3D) cell cultivation is a powerful technique for monitoring and understanding diverse cellular mechanisms in developmental cancer and neuronal biology, tissue engineering, and drug development. 3D systems could relate better to in vivo models than two-dimensional (2D) cultures. Several factors, such as cell type, survival rate, proliferation rate, and gene and protein express...

We construct a family of bright optical solitons composed fundamental-frequency (FF) and second-harmonic (SH) components in the one-dimensional (planar) waveguide with quadratic (second-harmonic-generating) nonlinearity effective fractional diffraction, characterized by Lévy index α, taking values between 2 0.5, which correspond to non-fractional diffraction critical collapse, respectively. The...
