Biosynthesis of Gold and Silver Nanoparticles Using <I>Emblica Officinalis</I> Fruit Extract, Their Phase Transfer and Transmetallation in an Organic Solution (2005)

The design, synthesis and characterization of biologically synthesized nanomaterials have become an area of significant interest. In this paper, we report the extracellular synthesis of gold and silver nanoparticles using Emblica Officinalis (amla, Indian Gooseberry) fruit extract as the reducing agent to synthesize Ag and Au nanoparticles, their subsequent phase transfer to an organic solution and the transmetallation reaction of hydrophobized silver nanoparticles with hydrophobized chloroaurate ions. On treating aqueous silver sulfate and chloroauric acid solutions with Emblica Officinalis fruit extract, rapid reduction of the silver and chloroaurate ions is observed leading to the formation of highly stable silver and gold nanoparticles in solution. Transmission Electron Microscopy analysis of the silver and gold nanoparticles indicated that they ranged in size from 10 to 20 nm and 15 to 25 nm respectively. Ag and Au nanoparticles thus synthesized were then phase transferred into an organic solution using a cationic surfactant octadecylamine. Transmetallation reaction between hydrophobized silver nanoparticles and hydrophobized chloroaurate ions in chloroform resulted in the formation of gold nanoparticles.
Electrode design and planer uniformity of anodically etched large area porous silicon (2001)

The structure of electrodes in the electrochemical formation cell of porous silicon greatly influences the planar uniformity of the porous silicon layer. In this paper a systematic study of the planar uniformity of large area porous silicon layer formed by different electrode structure is reported based on photoluminescence and reflectance scanning of the surface. A new design of the electrode structure is developed for achieving satisfactory planar uniformity of large area porous silicon layer.
Novel hemagglutinin nanoparticle influenza vaccine with Matrix-M™ adjuvant induces hemagglutination inhibition, neutralizing, and protective responses in ferrets against homologous and drifted A(H3N2) subtypes (2017)

Influenza viruses frequently acquire mutations undergoing antigenic drift necessitating annual evaluation of vaccine strains. Highly conserved epitopes have been identified in the hemagglutinin (HA) head and stem regions, however, current influenza vaccines induce only limited responses to these conserved sites. Here, we describe a novel seasonal recombinant HA nanoparticle influenza vaccine (NIV) formulated with a saponin-based adjuvant, Matrix-M™. NIV induced hemagglutination inhibition (HAI) and microneutralizing (MN) antibodies against a broad range of influenza A(H3N2) subtypes. In a comparison of NIV against standard-dose and high-dose inactivated influenza vaccines (IIV and IIV-HD, respectively) in ferrets NIV elicited HAI and MN responses exceeding those induced by IIV-HD against homologous A(H3N2) by 7 fold, A(H1N1) by 26 fold, and B strain viruses by 2 fold. NIV also induced MN responses against all historic A/H3N2 strains tested, spanning more than a decade of viral evolution from the 2000-2017 influenza seasons whereas IIV and IIV-HD induced HAI and MN responses were largely directed against the homologous A(H3N2), A(H1N1), and B virus strains. NIV induced superior protection compared to IIV and IIV-HD in ferrets challenged with a homologous or 10-year drifted influenza A(H3N2) strain. HAI positive and HAI negative neutralizing monoclonal antibodies derived from mice immunized with NIV were active against homologous and drifted influenza A(H3N2) strains. Taken together these observations suggest that NIV can induce responses to one or more highly conserved HA head and stem epitopes and result in highly neutralizing antibodies against both homologous and drift strains.

Batch-Fabricated, Addressable, Magnetically Actuated Microstructures (1996)

Surface-micromachined, batch-fabricated structures that combine plated-nickel films with polysilicon mechanical fl exures to produce individually addressable, magnetically activated devices have been fabricated and tested. Individual microactuator control has been achieved two ways: (1) by actuating devices using the magnetic fi eld generated by coils integrated around each device, (2) by using electrostatic forces to clamp selected devices to an insu lated ground plane while undamped devices are freely moved through large out-of-plane excursions by an off-chip magnetic fi eld. The present application for these structures is as micromirrors for microphotonic systems where they can be used either for selection from an array of mirrors or else individually for switching among fiber paths.
Recent Developments and Future Advancements in Solar Panels Technology (2020)

Abstract Although advancements and developments are happening on the electronics part of the solar cell, a steep boost in the research field of material and manufacturing perspective must highlight. Artificial intelligence-based maximum power point tracking algorithms are the future of solar-based circuits. Fabrication of transparent solar cells that have the potential to be used for a vast number of applications, solar cells with more than one layer of light capturing materials. Innovative photovoltaic modules that can lay on roads that can power LED lamps and can melt snow in winter are a few cutting-edge technologies from the materials as well as a manufacturing point of view. Surprisingly they have higher efficiency than traditional solar cells. This paper analyses the recent developments and the future potential of solar panel technologies in the material and manufacturing perspective.
An Inkjet-Printed Solar-Powered Wireless Beacon on Paper for Identification and Wireless Power Transmission Applications (2012)

This paper demonstrates the design of an 800-MHz solar-powered active wireless beacon composed of an antenna and an integrated oscillator on a low-cost paper substrate. Inkjet printing is used to fabricate the conductive circuit traces and the folded slot antenna, while the oscillator circuit is designed using off-the-shelf components mounted on the paper substrate. Flexible, low-cost, amorphous silicon (a-Si) solar cells are placed on top of the slot ground and provide autonomous operation of the active circuit eliminating the use of a battery. A prototype is built and characterized in terms of phase noise, radiation patterns, and the effect of solar irradiance. Such low-cost flexible circuits can find significant applications as beacon generator circuits for real-time identification and position purposes, wearable biomonitoring as well as solar-to-wireless power transfer topologies. The measured phase noise is -116 dBc/Hz at 1-MHz offset, while drain current is 4 mA and supply voltage is 1.8 V.
Isoxazole anthelmintics (1977)

<p>Chabazite zeolites with trimodal porosity (native micropores of the CHA framework, an additional network of larger micropores of ∼0.5 nm, and mesopores) were synthesized by adding diquarternary ammonium-type surfactant C<sub>22-4-4</sub> cations and fluoride anions in the synthesis of SSZ-13 zeolite. The hierarchical SSZ-13 zeolites are fully crystalline and exhibit similar acidity as bulk SSZ-13 zeolite. The increased diffusion rate in the hierarchical SSZ-13, proven by uptake experiments of bulky molecules and selective staining by thiophene oligomers, resulted in much slower catalyst deactivation in the methanol-to-olefins (MTO) reaction. Confocal fluorescent images of spent hierarchical SSZ-13 zeolites reveal homogeneous distribution of carbonaceous deposits, indicating that the micropore space has been completely utilized during the MTO reaction.

Galiellalactone is a novel therapeutic candidate against hormone‐refractory prostate cancer expressing activated Stat3 (2007)

Galiellalactone induced growth inhibition and apoptosis in androgen-insensitive PCa cells expressing p-Stat3. We suggest that galiellalactone is a potential anti-tumor lead against hormone-refractory PCa with constitutively active Stat3.
SpiderTrap—An Innovative Approach to Analyze Activity of Internet Bots on a Website (2020)

The main idea behind creating SpiderTrap was to build a website that can track how Internet bots crawl it. To track bots, honeypot dynamically generates different types of the hyperlinks on the web pages leading from one article to another and logs information passed by web clients in HTTP requests when visiting these links. By analyzing the sequences of visited links and passed HTTP requests it is possible to: detect bots, reveal bots' crawling or scanning algorithms, and other characteristic features of the traffic they generate. In our research we focused on identifying and describing whole bots' operations rather than just classifying single HTTP requests. This novel approach has given us insight into what different types of Internet bots are looking for and how they work. This information can be used to optimize the websites for search engines' bots for a better place on a search's results page or prepare a set of rules for tools that filter traffic to the web pages to minimize the impact of bad and unwanted bots on the websites' availability and security. We present the results of the five months of SpiderTrap's activity when honeypot was accessible by two domains (.pl and.eu), as well as by an IP address. The results show examples of activity of well-known Internet bots, such as Googlebot or Bingbot, unknown crawlers, and scanners trying to exploit vulnerabilities in the most popular web frameworks or looking for active webshells (i.e. access points to control a web server left by other attackers).

Mutagenesis and Repair Induced by the DNA Advanced Glycation End Product <i>N</i><sup>2</sup>-1-(Carboxyethyl)-2′-deoxyguanosine in Human Cells (2011)

Glycation of biopolymers by glucose-derived α-oxo-aldehydes such as methylglyoxal (MG) is believed to play a major role in the complex pathologies associated with diabetes and metabolic disease. In contrast to the extensive literature detailing the formation and physiological consequences of protein glycation, there is little information about the corresponding phenomenon for DNA. To assess the potential contribution of DNA glycation to genetic instability, we prepared shuttle vectors containing defined levels of the DNA glycation adduct N(2)-(1-carboxyethyl)-2'-deoxyguanosine (CEdG) and transfected them into isogenic human fibroblasts that differed solely in the capacity to conduct nucleotide excision repair (NER). In the NER-compromised fibroblasts, the induced mutation frequencies increased up to 18-fold relative to background over a range of ∼10-1400 CEdG adducts/10(5) dG, whereas the same substrates transfected into NER-competent cells induced a response that was 5-fold over background at the highest adduct density. The positive linear correlation (R(2) = 0.998) of mutation frequency with increasing CEdG level in NER-defective cells suggested that NER was the primary if not exclusive mechanism for repair of this adduct in human fibroblasts. Consistent with predictions from biochemical studies using CEdG-substituted oligonucleotides, guanine transversions were the predominant mutation resulting from replication of MG-modified plasmids. At high CEdG levels, significant increases in the number of AT → GC transitions were observed exclusively in NER-competent cells (P < 0.0001). This suggested the involvement of an NER-dependent mutagenic process in response to critical levels of DNA damage, possibly mediated by error-prone Y-family polymerases.
Fast Asynchronous Parallel Stochastic Gradient Descent: A Lock-Free Approach with Convergence Guarantee (2016)

Stochastic gradient descent (SGD) and its variants have become more and more popular in machine learning due to their efficiency and effectiveness. To handle large-scale problems, researchers have recently proposed several parallel SGD methods for multicore systems. However, existing parallel SGD methods cannot achieve satisfactory performance in real applications. In this paper, we propose a fast asynchronous parallel SGD method, called AsySVRG, by designing an asynchronous strategy to parallelize the recently proposed SGD variant called stochastic variance reduced gradient (SVRG). AsySVRG adopts a lock-free strategy which is more efficient than other strategies with locks. Furthermore, we theoretically prove that AsySVRG is convergent with a linear convergence rate. Both theoretical and empirical results show that AsySVRG can outperform existing state-of-the-art parallel SGD methods like Hogwild! in terms of convergence rate and computation cost.
Expression of luciferases from Vibrio harveyi and Vibrio fischeri in filamentous cyanobacteria (1986)

Shuttle vectors that had previously been shown to replicate both in Escherichia coli and in strains of Anabaena spp. were used to transfer the lux genes from Vibrio harveyi and Vibrio fischeri into Anabaena spp. The level of expression of luciferase in the cyanobacteria (up to 7,000 quanta cell-1 s-1) makes these genes good candidates for use as promoter probes during the differentiation of certain cells in a filament into heterocysts.
Fumigant toxicity of <i>Eucalyptus intertexta</i>, <i>Eucalyptus sargentii</i> and <i>Eucalyptus camaldulensis</i> against stored‐product beetles (2007)

Abstract: Three essential oils extracted from the species of the family Myrtaceae found in Kashan (centre regions of Iran) were shown to have potent fumigant toxicity against three major stored‐product insects: Callosobruchus maculatus (Fab.), Sitophilus oryzae (L.) and Tribolium castaneum (Herbst). These were the essential oils from Eucalyptus intertexta R.T. Baker, Eucalyptus sargentii Maiden and Eucalyptus camaldulensis Dehnh. The mortality of 1‐ to 7‐day‐old adults of the insect pests increased with concentration from 37 to 926 μ l/l air and with exposure time from 3 to 24 h. The LC 50 values to the selected essential oils were between 2.55 and 3.97 μ l/l air for C. maculatus , 6.93 and 12.91 μ l/l for S. oryzae and 11.59 and 33.50 μ l/l air for T. castaneum . Fumigant effects of these essential oils were considered to warrant further research into their potential for commercial use.
Duobinary signal generation using high-extinction ratio modulation (2008)

Two-Dimensional Metallic NiSe2 Nanoclusters–Based Low-Cost, Flexible, Amperometric Sensor for Detection of Neurological Drug Carbamazepine in Human Sweat Samples (2020)

Here we report a low-cost, flexible amperometric sensing platform for highly selective and sensitive detection of carbamazepine (CBZ) in human sweat samples. Detailed morphological characterization of the two-dimensional transition metal dichalcogenide NiSe<sub>2</sub>, synthesized using one-step hydrothermal method, confirms the formation of dense NiSe<sub>2</sub> nanoclusters in the range of 500-650 nm, whereas X-ray diffraction and X-ray photoelectron spectroscopy studies reveal a stable and pure cubic crystalline phase of NiSe<sub>2</sub>. The sensor device is fabricated by uniformly depositing an optimized weight percentage of as-synthesized NiSe<sub>2</sub> onto flexible and biocompatible polyimide substrate using spin coating, and metal contacts are established using thermal evaporation technique. The sensor exhibits a remarkable sensitivity of 65.65 μA/nM over a wide linear range of 50 nM to 10 μM CBZ concentrations and a low limit of detection of 18.2 nM. The sensing mechanism and excellent response of NiSe<sub>2</sub> toward CBZ can be attributed to the highly conductive metallic NiSe<sub>2</sub>, large electroactive surface area of its nanoclusters, and highly interactive Ni<sup>2+</sup>/Ni<sup>3+</sup> oxidation states. Furthermore, the presence of 10-fold excess of capable interferents, such as lactic acid, glucose, uric acid, and ascorbic acid, does not affect the accurate determination of CBZ, thus demonstrating excellent selectivity. The real-time detection of CBZ is evaluated in human sweat samples using standard addition method, which yields reliable results. Furthermore, the sensor shows excellent robustness when subject to bending cycles and fast response time of 2 s. The strategy outlined here is useful in developing sensing platforms at low potential without the use of enzymes or redox binders for applications in healthcare.
ElasticVR (2018)

We propose a light-weight, wearable device ElasticVR to provide various force feedback in multi-level in virtual reality (VR) for more immersive and realistic VR experiences. Force feedback is generally categorized into passive and active force feedback. Passive force is produced passively and continuously against the body part movement, e.g., elasticity and resistance. Active force is triggered by events and rendered actively and discretely to stimulate users, e.g., recoil and impact. ElasticVR consists of an elastic band, servo motors and mechanical locks to provide both passive and active force feedback. By changing length and extension distance of the elastic band, different elasticity levels produce various force feedback levels. By observing multi-level force feedback perception, we provide 5-level passive and 3-level active force feedback on the finger. We expect that realistic force feedback from ElasticVR enhances VR experiences.
Endometriosis: Associations with Menorrhagia, Infertility and Oral Contraceptives (1980)

In a retrospective study of 163 women with endometriosis, 76% had a history of menorrhagia, a larger percentage than that which might be normally expected. Only 10% of the women complained of infertility, while 13% had used oral contraceptives regularly, a much smaller proportion than expected. These findings are discussed in terms of the pathogenesis of endometriosis and the possible prophylactic role of oral contraceptives. The authors suggest the possibility that increased sensitivity to estrogens may lead to the development of endometriosis in some women.
September 2007 - News Archive - Boulder Laboratories Library - U.S. Department of Commerce (2005)

To assess whether patterns of HIV transmission have changed in Thailand, we tested for antibody to hepatitis C virus (HCV) as a marker for parenterally acquired infection among HIV-infected and uninfected young Thai men. Antibody to HCV was present in 49.5% of HIV-infected men and 2.2% among uninfected men. These data suggest that a significant number of HIV infections among young men in Thailand may be associated with injection drug use.
