Direct observation of bulk second-harmonic generation inside a glass slide with tightly focused optical fields
(American Physical Society, 2016-04-18)Bulk second-harmonic generation (SHG) inside glass slides is directly detected unambiguously without interference from surface contributions. This is enabled by tightly focused and highly localized ultrashort laser pulses. ... -
A Comparison of Four Approaches to Discretization Based on Entropy †
(MDPI, 2016-02-25)We compare four discretization methods, all based on entropy: the original C4.5 approach to discretization, two globalized methods, known as equal interval width and equal frequency per interval, and a relatively new method ... -
Constrained Type Families
(Association for Computing Machinery, 2017-09)We present an approach to support partiality in type-level computation without compromising expressiveness or type safety. Existing frameworks for type-level computation either require totality or implicitly assume it. For ... -
Contour Detection-based Discovery of Mid-level Discriminative Patches for Scene Classification
(Thieme Publishing, 2017-05-15)Feature extraction and representation is a key step in scene classification. In this paper, a contour detection-based mid-level features learning method is proposed for scene classification. First, a sketch tokens-based ... -
GRASPx: efficient homolog-search of short peptide metagenome database through simultaneous alignment and assembly
(BioMed Central, 2016-08-31)Background Metagenomics is a cultivation-independent approach that enables the study of the genomic composition of microbes present in an environment. Metagenomic samples are routinely sequenced using next-generation ... -
Metagenome and Metatranscriptome Analyses Using Protein Family Profiles
(PLoS, 2016-07-11)Analyses of metagenome data (MG) and metatranscriptome data (MT) are often challenged by a paucity of complete reference genome sequences and the uneven/low sequencing depth of the constituent organisms in the microbial ... -
Fiber Laser Based Two-Photon FRET Measurement of Calmodulin and mCherry-E0GFP Proteins
(Wiley, 2012-06)The speed and accuracy of Förster Resonance Energy Transfer (FRET) measurements can be improved by rapidly alternating excitation wavelengths between the donor and acceptor fluorophore. We demonstrate FRET efficiency ... -
Single fiber laser based wavelength tunable excitation for CRS spectroscopy
(Optical Society of America, 2013-06-01)We demonstrate coherent Raman spectroscopy (CRS) using a tunable excitation source based on a single femtosecond fiber laser. The frequency difference between the pump and the Stokes pulses was generated by soliton ... -
GPD: A Graph Pattern Diffusion Kernel for Accurate Graph Classification with Applications in Cheminformatics
(Institute of Electrical and Electronics Engineers, 2010-04)Graph data mining is an active research area. Graphs are general modeling tools to organize information from heterogeneous sources and have been applied in many scientific, engineering, and business fields. With the fast ... -
Artificial Neural Network Based Analysis of High Throughput Screening Data for Improved Prediction of Active Compounds
(SAGE Publications, 2009-12-14)Artificial Neural Networks (ANNs) are trained using High Throughput Screening (HTS) data to recover active compounds from a large data set. Improved classification performance was obtained on combining predictions made by ... -
Semantic Map Building Based on Object Detection for Indoor Navigation
(SAGE Publications, 2015-11-23)Building a map of the environment is a prerequisite for mobile robot navigation. In this paper, we present a semantic map building method for indoor navigation of a robot using only the image sequence acquired by a mon‐ ... -
Adiabatic far-field sub-diffraction imaging
(Nature Publishing Group, 2015-08-10)The limited resolution of a conventional optical imaging system stems from the fact that the fine feature information of an object is carried by evanescent waves, which exponentially decays in space and thus cannot reach ... -
Simulation of the Impact of Si Shell Thickness on the Performance of Si-Coated Vertically Aligned Carbon Nanofiber as Li-Ion Battery Anode
(MDPI, 2016)Micro- and nano-structured electrodes have the potential to improve the performance of Li-ion batteries by increasing the surface area of the electrode and reducing the diffusion distance required by the charged carriers. ... -
Research on the Fundamental Principles and Characteristics of Correspondence Function
(Hindawi Publishing Corporation, 2015)The correspondence function (CF) is a concept recently introduced to reject the mismatches from given putative correspondences. The fundamental idea of the CF is that the relationship of some corresponding points between ... -
Stereo correspondence based on curvelet decomposition, support weights, and disparity calibration
(Society of Photo-optical Instrumentation Engineers, 2010-04-13)A novel multiresolution analysis-based stereo matching method using curvelets, support weights, and disparity calibration is proposed. By introducing curvelet decomposition, we obtain the curvelet coefficients in different ... -
Shaping light beams in the nanometer scale: A Yagi-Uda nanoantenna in the optical domain
(American Physical Society, 2007-12-06)A Yagi-Uda-like optical nanoantenna concept using resonant core-shell plasmonic particles as its “reflectors” and “directors” is studied numerically. Such particles when placed near an optical dipole source in a certain ... -
Optical spectrometer at the nanoscale using optical Yagi-Uda nanoantennas
(American Physical Society, 2009-05-05)Here we present and analyze an optical spectrum analyzer at the nanometer scale that is able to distribute different frequency contents of the radiation of an optical dipole source into different directions in the space. ... -
Far-field subdiffraction optical microscopy using metamaterial crystals: Theory and simulations
