An Image Based Microtiter Plate Reader System for 96-well Format Fluorescence Assays (2013)

Background: 96-well microtiter plate assay are becoming popular analytical procedures in laboratory and clinical practices generating a demand for microtiter plate readers. The present colorimetric and fluorimetric based microtiter plate reader are efficient in general applications such as measuring reflectance, absorbance, and optical density of reaction mixtures. However, a dedicated system incorporating automation and computational techniques in specific microtiter plate readers for Drug discovery and Microbial viability, provides portability and compatibility with highthroughput analysis at affordable cost. Objective: To develop image-based reader system for semi-quantitative measurements of transport assay performed in microtiter plate. In this work, we focus on deduction of illumination source and classification of fluorescence emitted by transport assay using this microtiter plate reader. Method: We have taken the images of 96-well fluorescence efflux assay and developed an appropriate image analysis system to read the individual well images and categorize the results as fast efflux and slow efflux by the classifier. The images exhibited non-uniform illumination due to UV transilluminator, which then replaced by the circuit of blue LED after performing a study on its classification performance.
Weighted empirical distribution based approach to Chance Constrained Optimization Problems using Differential Evolution (2017)

This paper proposes a new approach to solve Chance Constrained Optimization Problems (CCOPs). The stochastic objective and constraint values in CCOP are evaluated efficiently by using an approximation of Cumulative Distribution Function (CDF) instead of the primitive Monte Carlo simulation. In order to approximate CDF from samples, a technique of the computational statistics called Empirical CDF (ECDF) is widely known. In this paper, an improved version of ECDF named Weighted Empirical CDF (W ECDF) is used. Then, for solving CCOP, a modified Differential Evolution (DE) combined with W ECDF is proposed. The results of numerical experiments show that DE with W ECDF finds a feasible solution of CCOP and outperforms DE with ECDF in the accuracy of solution.
Characterization of Cellulose/Calcium Carbonate Biocomposite Film (2016)

In this study were to explore the properties of interaction between cellulose and calcium carbonate particle (CaCO 3 ) which derive from Papia Undulates Shell in procedure of biocomposite synthesis. The structural properties of cellulose powder Papia Undulates Shell and cellulose-calcium carbonate composite film were investigated by using X-ray Diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) and the compositions of cellulose/CaCO 3 biocomposite film were studied by Energy Dispersive X-ray Fluorescence (EDXRF). The experimental results demonstrated the morphology of Papia Undulates Shell were crystalline aragonite phase and the cellulose have structural as amorphous-crystalline but after film forming the composite film between cellulose and Papia Undulates Shell also have amorphous structural. The result of FTIR used to confirmed the formation of bonding between molecular, it indicated that the cellulose/CacO 3 biocomposite film had good biocompatibility due to the biocomposite film have both characteristic feature of CO 3 -2 group (~874 cm -1 and ~713 cm -1 ) and the glucose of cellulose at ~1635, ~1064 and ~946 cm -1 . Another that, the result from EDXRF shown the chemical composition of organic compound of cellulose/CaCO 3 biocomposite film was highest with 99.437 while the Papia Undulates Shell have 0.341 Wt% with corresponding with the ratio of filler material which mixture as 1%. So that, the cellulose/calcium carbonate bicomposite film could be candidate for biocomposite film application.

Protein Conformational Changes of <i>Agrobacterium</i> Phytochrome Agp1 during Chromophore Assembly and Photoconversion (2007)

Phytochromes are widely distributed photochromic biliprotein photoreceptors. Typical bacterial phytochromes such as Agrobacterium Agp1 have a C-terminal histidine kinase module; the N-terminal chromophore module induces conformational changes in the protein that lead to modulation of kinase activity. We show by protein cross-linking that the C-terminal histidine kinase module of Agp1 mediates stable dimerization. The fragment Agp1-M15, which comprises the chromophore module but lacks the histidine kinase module, can also form dimers. In this fragment, dimer formation was stronger for the far-red-absorbing form Pfr than for the red-absorbing form Pr. The same or similar behavior was found for Agp1-M15Delta9N and Agp1-M15Delta18N, which lack 9 and 18 amino acids of the N-terminus, respectively. The fragment Agp1-M20, which is derived from Agp1-M15 by truncation of the C-terminal "PHY domain" (191 amino acids), can also form dimers, but dimerization is independent of irradiation conditions. The cross-linking data also showed that the PHY domain is in tight contact with Lys 16 of the protein and that the nine N-terminal amino acids mediate oligomer formation. Limited proteolysis shows that the hinge region between the chromophore module and the histidine kinase and a part of the PHY domain become exposed upon Pr to Pfr photoconversion.

A pre-study on the potential plants to treat heavy metals in contaminated soil (2012)

Heavy metals are among the most important sorts of contaminant in the environment.Several methods already used to clean up the environment from these kinds of contaminants,but most of them are costly and difficult to get optimum results.Currently,phytoremediation is an effective and affordable technological solution used to extract or remove metal pollutants from contaminated soil and water.This study was aimed to evaluate the potential of 4 types of green plants for phytoremediation purpose and also to study the effect of contact time to uptake heavy metals such as Pb,Cd,Cr and Zn.Four types of green plants namely Cosmos caudatus (ulam raja),Centella asiatica (pegaga),Emilia sonchifolia (bayam praksi) and Oenanthe javanica (daun selom) were selected because they are fast-growth plant species,cheap in price and also have a substantial supply.Plant materials were acid digested and analyzed with the standard laboratory method by using Flame-Atomic Absorption Spectroscopy (AAS) to determine the total metal concentrations in plant samples.This study was perhaps one of the first to evaluate the feasibility of these green plants species for phytoremediation purpose.Results showed that all the studied green plant species possessed different metal concentrations where lead appeared to be the most metal being accumulated by C.caudatus (0.905 mg/L), cadmium was found to be highly accumulated by O.javanica (0.913 mg/L), chromium highly accumulated by C.asiatica (0.340 mg/L) and zinc was the most metal being accumulated by E.sonchifolia (2.460 mg/L).It also was found that the percentage of metal uptake by the plant increased with the increasing of time.
146th Audio Engineering Society Convention (2019)

Given that traditional music production techniques often incorporate analog audio hardware, the Internet of Things (IoT) presents a unique opportunity to maintain past production workflows. For example, it is possible to enable remote digital connectivity to rare, expensive and bespoke audio systems, as well as unique spaces for use as echo chambers. In the presented research, quantitative testing is conducted to verify the performance of audio streaming platforms. Results show that using a high-speed internet connection, it is possible to stream lossless audio with low distortion, no dropouts and around 30 ms round-trip latency. Therefore, with future integration of audio streaming and IoT control protocols, a new paradigm for remote analog hardware processing in music production could be enabled.
Body Movements for Affective Expression: A Survey of Automatic Recognition and Generation (2013)

Body movements communicate affective expressions and, in recent years, computational models have been developed to recognize affective expressions from body movements or to generate movements for virtual agents or robots which convey affective expressions. This survey summarizes the state of the art on automatic recognition and generation of such movements. For both automatic recognition and generation, important aspects such as the movements analyzed, the affective state representation used, and the use of notation systems is discussed. The survey concludes with an outline of open problems and directions for future work.
Influence of transmission distance on XPM-inducedintensitydistortion in dispersion-managed, amplified fibre links (1999)

The variation of cross-phase modulation (XPM) induced distortion with transmission distance is investigated for dispersion-managed fibre links using a recirculating loop. New results are reported showing the distance dependence of the XPM-induced distortion in an IM-DD system on channel spacing and dispersion. It is demonstrated that the acquired XPM distortion can be effectively reduced by use of additional dispersive fibre at the receiver.
BUILDING THE EMPIRE OF THE GAZE: The Modern Movement and the Surveillance Society (1999)

The paper draws on Michel Foucault's notion of the surveillance society to develop criticism of the Modern Movement. The contention is that Modern architecture was not only symptomatic of the shift to the surveillance society, but that it was also complicit in its development through the discursive imperative of total visibility at the heart of Western metaphysics, modernity and Modernism. It is argued that salient features of the Modernist discourse—glass, the interior, the house and factory—represent architectonic mechanisms of disciplinary power. “Spatial images are the dreams of society. Wherever the hieroglyphics of any spatial image are deciphered, there the basis of social reality presents itself.”1 Siegfried Kracauer
Deep learning for actinic keratosis classification (2019)

Classification of biological images plays a crucial role in many biological problems, e.g. recognition of cell phenotypes and maturation levels, localization of cell organelles and histopathological classification, and holds the potential to support early diagnosis, which is critical in disease prevention. In this paper, we tested different ensemble of canonical and deep classifiers to provide accurate identification of actinic keratosis (AK), one of the most common skin lesions that could degenerate into lethal squamous cell carcinomas.<br />We used a clinical image dataset to build and test different ensembles of support vector machines trained by handcrafted descriptors and convolutional neural networks (CNNs) for which we experimented different learning rates, augmentation techniques (e.g. warping) and topologies.<br />Our results show that the proposed ensemble obtains performance comparable to the state of the art. To reproduce the experiments reported in this paper, the MATLAB code of all the descriptors is available at https://github.com/LorisNanni.
2-Hexylthio-β,γ-CH<sub>2</sub>-ATP is an Effective and Selective NTPDase2 Inhibitor (2014)

NTPDase2 catabolizes nucleoside triphosphates and consequently, through the interaction of nucleotides with P2 receptors, controls multiple biological responses. NTPDase2 inhibitors could modulate responses induced by nucleotides in thrombosis, inflammation, cancer, etc. Here we developed a set of ATP analogues as potential NTPDase inhibitors and identified a subtype-selective and potent NTPDase2 inhibitor, 2-hexylthio-β,γ-methylene-ATP, 2. Analogue 2 was stable to hydrolysis by NTPDase1, -2, -3, and -8. It inhibited hNTPDase2 with Ki 20 μM, while only marginally (5-15%) inhibiting NTPDase1, -3, and -8. Homology models of hNTPDase1 and -2 were constructed. Docking and subsequent linear interaction energy (LIE) simulations provided a correlation with r2=0.94 between calculated and experimental inhibition data for the triphosphate analogues considered in this work. The origin of selectivity of 2 for NTPDase2 over NTPDase1 is the thiohexyl moiety of 2 which is favorably located within a hydrophobic pocket, whereas in NTPDase1 it is exposed to the solvent.
A Rapid Prototyping Technique for Microfluidics with High Robustness and Flexibility (2016)

In microfluidic device prototyping, master fabrication by traditional photolithography is expensive and time-consuming, especially when the design requires being repeatedly modified to achieve a satisfactory performance. By introducing a high-performance/cost-ratio laser to the traditional soft lithography, this paper describes a flexible and rapid prototyping technique for microfluidics. An ultraviolet (UV) laser directly writes on the photoresist without a photomask, which is suitable for master fabrication. By eliminating the constraints of fixed patterns in the traditional photomask when the masters are made, this prototyping technique gives designers/researchers the convenience to revise or modify their designs iteratively. A device fabricated by this method is tested for particle separation and demonstrates good properties. This technique provides a flexible and rapid solution to fabricating microfluidic devices for non-professionals at relatively low cost.

Multimedia conference system based on SIP is a real-time interactive communication service with multimedia applications, e.g., audio, video, whiteboard, and all users in the system should have the SIP clients which can create or receive SIP messages and send or display audio or video data for multimedia conference system. In this paper, the design and implementation of SIP User-Agent as applet for multimedia conference system is introduced which can run in Web browser. All modules of SIP UA are introduced separately, including user interface, call control module, media processing module and JAIN SIP stack. The test results prove that the system can correctly carry out multimedia communication.
Sex attractants for male lepidoptera. (1977)

About one hundred of unsaturated long straight chain compounds (C10-C18) containing a terminal hydroxyl or acetoxyl group were synthesized and their attractiveness to male Lepidoptera were tested in various environments. In this screening test, male insects of ninetythree species which belong to fifteen families were attracted specifically. It was indicated that monoene alcohols and acetates constitute a main group of sex pheromones of the Lepidoptera being native in Japan. Discussions are made on the structure-activity relationship in the attractants and on the chemical structural features of components, which are expected to be present commonly in the certain family, namely, Torticidae, Noctuidae etc.
IFATS Collection: Adipose Stromal Cells Adopt a Proangiogenic Phenotype Under the Influence of Hypoxia (2008)

Evolving evidence suggests a possible role for adipose stromal cells (ASCs) in adult neovascularization, although the specific cues that stimulate their angiogenic behavior are poorly understood. We evaluated the effect of hypoxia, a central mediator of new blood vessel development within ischemic tissue, on proneovascular ASC functions. Murine ASCs were exposed to normoxia (21% oxygen) or hypoxia (5%, 1% oxygen) for varying lengths of time. Vascular endothelial growth factor (VEGF) secretion by ASCs increased as an inverse function of oxygen tension, with progressively higher VEGF expression at 21%, 5%, and 1% oxygen, respectively. Greater VEGF levels were also associated with longer periods in culture. ASCs were able to migrate towards stromal cell-derived factor (SDF)-1, a chemokine expressed by ischemic tissue, with hypoxia augmenting ASC expression of the SDF-1 receptor (CXCR4) and potentiating ASC migration. In vivo, ASCs demonstrated the capacity to proliferate in response to a hypoxic insult remote from their resident niche, and this was supported by in vitro studies showing increasing ASC proliferation with greater degrees of hypoxia. Hypoxia did not significantly alter the expression of endothelial surface markers by ASCs. However, these cells did assume an endothelial phenotype as evidenced by their ability to tubularize when seeded with differentiated endothelial cells on Matrigel. Taken together, these data suggest that ASCs upregulate their proneovascular activity in response to hypoxia, and may harbor the capacity to home to ischemic tissue and function cooperatively with existing vasculature to promote angiogenesis.
A synchronous adaptive noise canceller for periodic interference (2005)

A new type adaptive noise canceller for periodic interference is proposed. The operation of this adaptive filter is controlled by the phase-locked loop which captures the fundamental frequency component of the noise and generates clock pulse whose frequency is N times that of it, where N is the length of the impulse response function of the adaptive filter. This clock is used to keep the operation of the adaptive filter synchronous with the noise and also to keep the length of the impulse response function of the adaptive filter equal to the noise period. By the usual least-mean-squares (LMS) algorithm there needs 2N multiplications and 2N additions far the correction of the filter coefficients at each sampling time. However, the synchronous method needs only one multiplication and one addition. It means that the total computational cost decreases to about 1/(2N) times as compared with the usual LMS algorithm and it will be a great help in simplifying the hardware construction and also in widening the operational frequency range of the adaptive filter. A pilot study has showed the proposed adaptive filter has excellent performance.
Controlling Synergistic Oxidation Processes for Efficient and Stable Blue Thermally Activated Delayed Fluorescence Devices (2016)

Efficient sky-blue organic light-emitting diodes (OLEDs) employing thermally activated delayed fluorescence (TADF) display a three orders of magnitude increase in lifetime, which is superior to those of controlled phosphorescent OLEDs used in this study. The combination of electro-oxidation and photo-oxidation of the TADF emitters in their triplet excited-states is suppressed through molecule design and device engineering.
Steps toward child-designed interactive stuffed toys (2011)

Within the past decade, computationally-enhanced toys have become a staple of children's environments. In large part, this is due to the small size, robust operation, and low cost of embedded computing that enables computers (and associated electronic devices) to be included within toys of all descriptions. More recently, a variety of powerful technologies have emerged so that children can design their own computational artifacts: that is, small (and inexpensive) processors, sensors, and actuators have been developed that are well-suited to combination with "soft" materials such as textiles. This paper describes Plushbot, a system-in-development that allows children to create their own plush toys and stuffed animals, and to include computational enhancements within the toys that they create. Thus, Plushbot represents a step toward expanding children's creative design of their own interactive, computationally-enhanced characters. The paper describes the current state of the Plushbot software, shows a sample project created with the system, and describes plans for upcoming pilot tests with the system.
Pulsed thrust measurements using laser interferometry (1997)

An optical interferometric proximeter system (IPS) for measuring thrust and impulse bit of pulsed electric thrusters was developed. Unlike existing thrust stands, the IPS-based thrust stand offers the advantage of a single system that can yield electromagnetic interference-free, high accuracy (&lt;2% error) thrust measurements within a very wide range of impulses (100 μN s to above 10 N s) covering the impulse range of all known pulsed plasma thrusters. In addition to pulsed thrusters, the IPS is theoretically shown to be capable of measuring steady-state thrust values as low as 20 μN for microthrusters such as the field emission electric propulsion thruster. The IPS-based thrust stand relies on measuring the dynamic response of a swinging arm using a two-sensor laser interferometer with 10 nm position accuracy. The wide application of the thrust stand is demonstrated with thrust measurements of an ablative pulsed plasma thruster and a quasi-steady magnetoplasmadynamic thruster.
