In this paper, we give a review on Bilateral filtering as a tool for image smoothing with edge preserving properties. Bilateral filtering is a combination of domain and range filtering. Domain filtering measures the geometric closeness between the neighborhood center and nearby points. Therefore, domain filtering acts as a gaussian filtering. In range filtering, the similarity between two pixels are measured in which similar pixel values are weighted as a high influence while discarding dissimilar ones. We give a review on traditional bilateral filtering. We also describe a modified bilateral filtering based on fuzzy membership function, the fuzzy bilateral filtering. In fuzzy bilateral filtering, the skin is smoothed while maintaining the edges and non skin area, therefore, a more beautiful face image can be achieved. We will demonstrate some of its applications especially on skin smoothing. © 2014 IEEE. Source

This study aimed to search for the best indicator to be used for the harvest of maize pods for baby corn production. A Randomized Complete Block Design (RCBD) with four replications was used. The treatments are: T 1(Control) Taking sample when silks of female flower had extended from tip of pod up to 3 cm long T 2, silks had extended 1 cm long T 3, silks had extended 2 cm long T 4, blooming of female flower for 2 days T 5, blooming of female flowers for 4 days T 6, blooming of female flower for 6 days T 7, one third blooming of male flower T 8, two third blooming of male flower and T 9, full bloom of male flower. Five baby corn Characteristics were used i.e., (1) fresh weight of whole ears, (2) fresh weight of ears without husk, (3) commercial standard ears, (4) off standard ears and (5) disordered kernel-rows of ears. A range of scores from 1 to 9 was applied to judge quality and yield in each item of the five baby corn characteristics. A score of 1 = the best whilst further increases in scores indicated the decline in quality of baby corn. The results showed that an indicator for use in harvesting pods of maize for baby corn production was found with T 6, i.e. the best time for the harvest of pods is when the female flowers had bloomed for 6 days after the appearance of silks. © 2011 Asian Network for Scientific Information.

In this study, we demonstrate an ability to control the photophysical properties of nanoparticles of regioregular poly(3-octylthiophene) (rr-P3OT) by utilizing solvent-nonsolvent system. The strength of local polymer-solvent interactions is controlled by using hexane or hexanol as a poor solvent. We have found that the assembling of rr-P3OT chains in mixtures of toluene and these poor solvents results in the formation of nanoparticles with average diameter of about 35 nm. Interestingly, the use of hexane or hexanol as a poor solvent causes drastic variation of photophysical properties of the resultant nanoparticles. Their absorption spectra show quite different patterns. In addition, the photoluminescent (PL) peaks are detected at 565 nm and 645 nm in the systems of toluene/hexane and toluene/hexanol, respectively. Photoemission quantum efficiency of the nanoparticles also depends significantly on type of the poor solvents. We further demonstrate that the photophysical properties can be systematically controlled by using a series of linear alcohols as poor solvents. The increase of alcohol chain length causes the decrease of its polarity, which in turn improves the polymer-solvent interactions. In the system of toluene/decanol, PL spectrum of the nanoparticles covers relatively broad energy region, ranging from about 540 to 770 nm. Our study provides a simple method for preparation of rr-P3OT nanoparticles with controllable photophysical properties. © 2015 Elsevier B.V. All rights reserved. Source

Gold nanoshells (AuNSs) are currently being investigated as nanocarriers for drug delivery systems and have both diagnostic and therapeutic applications, including photothermal ablation, hyperthermia, drug delivery, and diagnostic imaging, particularly in oncology. AuNSs are valuable for their localized surface plasmon resonance, biocompatibility, low immunogenicity, and facile functionalization. AuNSs used for drug delivery can be spatially and temporally triggered to release controlled quantities of drugs inside the target cells when illuminated with a near-infrared (NIR) laser. Recently, many research groups have demonstrated that these AuNS complexes are able to deliver antitumor drugs (e.g., doxorubicin, paclitaxel, small interfering RNA, and single-stranded DNA) into cancer cells, which enhances the efficacy of treatment. AuNSs can also be functionalized with active targeting ligands such as antibodies, aptamers, and peptides to increase the particles' specific binding to the desired targets. This article reviews the current research on NIR light-activatable AuNSs used as nanocarriers for drug delivery systems and cancer theranostics. © 2014 American Association of Pharmaceutical Scientists.

Well-known conductive molecular wires, such as cumulene or polyyne, provide a model for interconnecting molecular electronics circuits. In recent experiments, the appearance of carbon wire bridging between two-dimensional electrodes, i.e., graphene sheets, was observed, thus demonstrating a mechanical way of producing cumulene. In this work, we studied the structure and conductance of carbon wire suspended between carbon nanotubes (CNTs) of different chiralities (zigzag and armchair), and corresponding conductance variation upon stretching. We found that the geometric structure of the carbon wire bridging CNTs was similar to the experimentally observed structures in carbon wire obtained between graphene electrodes. We show a way to modulate conductance by changing bridging sites between carbon wire and CNTs without breaking the wire. Observed current modulation via cumulene wire stretching or elongation together with CNT junction stability makes this a promising candidate for use in mechano-switching devices for molecular nanoelectronics. © 2013 American Physical Society.
