Proximity-induced unconventional superconductivity in topological insulators
We study and classify the proximity-induced superconducting pairing in a topological insulator (TI)-superconductor (SC) hybrid structure for SCs with different symmetries.

Surface acoustic waves for acousto-optic modulation in buried silicon nitride waveguides [PDF]
We theoretically investigate the use of Rayleigh surface acoustic waves (SAWs) for refractive index modulation in optical waveguides consisting of amorphous dielectrics.

ON THE PROXIMATE ORDER OF AN ENTIRE FUNCTION WITH INDEX PAR
Let \(f(z)\) be an entire function of \((p,q)\)-order \(\rho\) and \(w(r)\), defined on \((0,\infty)\), be a proximate order of \(f(z)\) satisfying \[ \lim_{r\to \infty}w(r) = \rho,\quad \lim_{r\to \infty}w'(r)F_{[q]}(r) = 0 \] where \[ F_{[q]}(r) = \prod^{q}_{i=0}\log^{[i]}x,\quad \log^{[0]}x=x, \] \[ \log^{[i]}x = \log (\log^{[i-1]}x). \] If \(\phi(r)

Time-resolved refractive index and absorption mapping of light-plasma filaments in water
By means of a quantitative shadowgraphic method, we performed a space-time characterization of the refractive index variation and transient absorption induced by a light-plasma filament generated by a 100 fs laser pulse in water.

A Semantic Proximity Based System of Arabic Text Indexation [PDF]
In this paper, we extended the vectorial model of Salton [9], [11], [12] and [14], by adapting the TF-IDF parameter by its combination with the Okapi formula for index terms extraction and evaluation of the in order to identify the relevant concepts which represent a document.

KEDEKATAN STRATEGIS INDONESIA DALAM RIVALITAS AS–CINA PASCA COVID-19
This study develops a Proximity Index to measure Indonesia's proximity to the United States and China, particularly after the COVID-19 pandemic. The index integrates three dimensions (economic, military, and diplomatic) to operationalize proximity as a ...

New bounds on proximity and remoteness in graphs
The average distance of a vertex $v$ of a connected graph $G$ is the arithmetic mean of the distances from $v$ to all other vertices of $G$. The proximity $\pi(G)$ and the remoteness $\rho(G)$ of $G$ are defined as the minimum and maximum ...
