Let $R$ be a commutative ring with $1 \ne 0$ and let $m$ and
 $n$ integers $1\leq n < m$. A proper ideal $I$ of is
 called an $(m, n)$-closed if whenever $a^m \in I$ for
 some $a\in R$ implies $a^n I$. $ f:A\rightarrow B$ a
 homomorphism $J$ $B.$ This paper
 investigates the concept $(m,n)$-closed ideals in the
 amalgamation $A$ $B$ along respect $f$ denoted by&...

The current smallest self-contained modular robot uses a shape memory alloy, which is inherently inefficient, slow and difficult to control. We present the design, fabrication and demonstration of a module based on dielectric elastomer actuation. The module uses a pair of bowtie dielectric elastomer actuators in an agonist-antagonist configuration and is seven times smaller than previously demo...

Near-field transducer based on nanoscale optical antenna has been shown to generate high transmission and strongly localized optical spots well below the diffraction limit. In this paper, nanoscale ridge aperture antenna is considered as near-field transducer for heat-assisted magnetic recording. The spot size and transmission efficiency produced by ridge aperture are numerically studied. We sh...

Currently, submission of new SNP entries into SNP repositories such as dbSNP by NCBI is done by manual curation. This gives rise to errors and ambiguities in SNP data entries. Due to the exponential increase in SNP discovery, there is a necessity to create algorithms to accurately and rapidly map SNPs as they are discovered in real time and depositing these entries automatically into a central ...

Plasmonic lasers exploit strong electromagnetic field confinement at dimensions well below the diffraction limit. However, lasing from an electromagnetic hot spot supported by discrete, coupled metal nanoparticles (NPs) has not been explicitly demonstrated to date. We present a new design for a room-temperature nanolaser based on three-dimensional (3D) Au bowtie NPs supported by an organic gain...
