Visualization of time-dependent flow fields (1993)

Presently, there are very few visualization systems available for time-dependent flow fields. Although existing visualization systems for instantaneous flow fields may be used to view time-dependent flow fields at discrete points in time, the time variable is usually not considered in the visualization technique. We present a simple and effective approach for visualizing time-dependent flow fields using streaklines. A system was developed to demonstrate this approach. The system can process many time frames of flow fields without requiring that all the data be in memory simultaneously, and it also handles flow fields with moving grids. We have used the system to visualize streaklines from several large 3-D time-dependent flow fields with moving grids. The system was able to provide useful insights to the physical phenomena in the flow fields. >
Fast Power-Peaks Estimator for Partially Shaded PV Systems (2015)

Model-based maximum power point tracking (MPPT) techniques have been developed recently to improve the dynamic and steady-state performance of MPPT. Although they are successfully implemented in homogeneous photovoltaic (PV) systems, there is still no model-based MPPT for partially shaded PV systems, mainly because the available models are complex and time consuming. This paper develops a fast modeling approach for partially shaded PV systems. By utilizing three developed rules that govern the formation of power peaks in partially shaded PV systems, the proposed approach can quickly find the power peaks of these systems without simulating the entire power curve. The effectiveness of the proposed approach in finding the power peaks of PV systems quickly and accurately is verified using MATLAB-Simulink and real-time simulator in hardware in the loop application. Moreover, a model-based MPPT is developed utilizing the proposed modeling method. The developed MPPT successfully improves the dynamic performance of power extraction, guarantees the operation on the global maximum power peak, and eliminates oscillating steady-state power losses.

Emerging topic detection using dictionary learning (2011)

Streaming user-generated content in the form of blogs, microblogs, forums, and multimedia sharing sites, provides a rich source of data from which invaluable information and insights maybe gleaned. Given the vast volume of such social media data being continually generated, one of the challenges is to automatically tease apart the emerging topics of discussion from the constant background chatter. Such emerging topics can be identified by the appearance of multiple posts on a unique subject matter, which is distinct from previous online discourse. We address the problem of identifying emerging topics through the use of dictionary learning. We propose a two stage approach respectively based on detection and clustering of novel user-generated content. We derive a scalable approach by using the alternating directions method to solve the resulting optimization problems. Empirical results show that our proposed approach is more effective than several baselines in detecting emerging topics in traditional news story and newsgroup data. We also demonstrate the practical application to social media analysis, based on a study on streaming data from Twitter.

Towards Agents and Ontology for Cloud Service Discovery (2011)

Cloud computing has attracted great interest from both academic and industrial communities. However, only a few efforts have been devoted to building tools for supporting Cloud service discovery. In this paper, we present a four-stage, agent-based Cloud service discovery protocol. Utilizing an ontology description, in which each resource is described semantically and relatively to other resources, we develop a multi-agent system that cooperates efficiently by introducing a flexible ontology-based matching. To increase the utility and success rate of matching consumers' requests to resources, we use a database to store and keep track of historical data for making intelligent recommendation based on attribute value prediction. Empirical results show that when broker agents in our system use a Cloud ontology and a connection procedure with a recommendation stage achieved better performance in finding the appropriate Cloud services than when broker agents 1) use only the connection procedure but not the Cloud ontology and 2) do not use both the connection procedure and the Cloud ontology.
Biochemical characterization and inhibitor discovery of shikimate dehydrogenase from <i>Helicobacter pylori</i> (2006)

Shikimate dehydrogenase (SDH) is the fourth enzyme involved in the shikimate pathway. It catalyzes the NADPH-dependent reduction of 3-dehydroshikimate to shikimate, and has been developed as a promising target for the discovery of antimicrobial agent. In this report, we identified a new aroE gene encoding SDH from Helicobacter pylori strain SS1. The recombinant H. pylori shikimate dehydrogenase (HpSDH) was cloned, expressed, and purified in Escherichia coli system. The enzymatic characterization of HpSDH demonstrates its activity with k(cat) of 7.7 s(-1) and K(m) of 0.148 mm toward shikimate, k(cat) of 7.1 s(-1) and K(m) of 0.182 mm toward NADP, k(cat) of 5.2 s(-1) and K(m) of 2.9 mm toward NAD. The optimum pH of the enzyme activity is between 8.0 and 9.0, and the optimum temperature is around 60 degrees C. Using high throughput screening against our laboratory chemical library, five compounds, curcumin (1), 3-(2-naphthyloxy)-4-oxo-2-(trifluoromethyl)-4H-chromen-7-yl 3-chlorobenzoate (2), butyl 2-{[3-(2-naphthyloxy)-4-oxo-2-(trifluoromethyl)-4H-chromen-7-yl]oxy}propanoate (3), 2-({2-[(2-{[2-(2,3-dimethylanilino)-2-oxoethyl]sulfanyl}-1,3-benzothiazol-6-yl)amino]-2-oxoethyl}sulfanyl)-N-(2-naphthyl)acetamide (4), and maesaquinone diacetate (5) were discovered as HpSDH inhibitors with IC(50) values of 15.4, 3.9, 13.4, 2.9, and 3.5 microm, respectively. Further investigation indicates that compounds 1, 2, 3, and 5 demonstrate noncompetitive inhibition pattern, and compound 4 displays competitive inhibition pattern with respect to shikimate. Compounds 1, 4, and 5 display noncompetitive inhibition mode, and compounds 2 and 3 show competitive inhibition mode with respect to NADP. Antibacterial assays demonstrate that compounds 1, 2, and 5 can inhibit the growth of H. pylori with MIC of 16, 16, and 32 microg.mL(-1), respectively. This current work is expected to favor better understanding the features of SDH and provide useful information for the development of novel antibiotics to treat H. pylori-associated infection.
A combinatorial approach to temporal reasoning (2002)

It is described how representation structures for counting the number of endpoint sequences associated with a given interval order or interval graph can be used in temporal reasoning. Efficient algorithms for constructing such structures from temporal data are designed and analyzed. The endpoint sequence closure problem for temporal (interval) data is defined here as the problem of determining all possible interval representations consistent with the given data. The results demonstrate polynomial time solutions to several special cases of the endpoint sequence closure problem and suggest a number of directions for further research.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Developmental changes in arachidonic acid potentiation of NMDA currents in cortical neurones (1996)

Developmental changes in the effects of arachidonic acid (AA) on N-methyl-D-aspartate (NMDA) receptor-mediated currents were investigated in acutely dissociated rat cortical neurones using a whole-cell patch-clamp method. AA potentiated peak NMDA currents (INMDA) in a concentration-dependent manner. Potentiation by AA was greater at 2-4 postnatal days (P2-4) than at P7-8 and P15-18. Indomethacin reduced the potentiating effect of AA only at P2-4, while caffeic acid and baicalein showed no apparent effect, indicating that metabolites of the cyclooxygenase pathway contribute to INMDA potentiation at P2-4. Staurosporine diminished the potentiation of INMDA at P2-4, suggesting that protein kinase C might participate in the effect of AA. These findings suggest that the greater potentiation of INMDA by AA at P2-4 has a different underlying mechanism from effects seen at P7-8 or older.
Evaluation of a dried blood spot HIV-1 RNA program for early infant diagnosis and viral load monitoring at rural and remote healthcare facilities (2009)

Under program conditions in Tanzania, DBS provided HIV-1 RNA results comparable to conventional methods to remote healthcare facilities. DBS RNA testing is an alternative to liquid plasma for HIV-1 RNA services in remote areas.
Debug Aware AXI-based Network Interface (2011)

With a significant increase in the complexity of cores and their intercommunications, there is a need to review and enhance traditional debug methods for System on Chips (SoCs). As new SoCs tend to have many cores, the interactions among cores through functional interconnects such as bus or Network on Chips (NoCs) are becoming so complex. Therefore, debug techniques should address not only validation of the computational part of a design but such techniques have to monitor and validate the communication and synchronization among cores inside SoCs. In this paper, we consider NoC as a functional interconnection among cores and propose debug aware network interface (NI) which is compatible with AXI standard. The proposed interface enables provides a mechanism for cross-trigger debugging. Transactions issued by a processing element connected to the proposed debug aware NI are monitored by the proposed cross-trigger unit and trace data and trigger events will be extracted and routed to another processing element or Shared Debugging Unit (SDU). SDU combines debug traces from different processing elements. The major benefits of using our proposed architectures for debugging over traditional techniques are as follows: 1) the proposed debug aware NI can detect, mark and bypass severe faulty conditions such as deadlocks resulting from design errors or electrical faults in real time 2) there is no need for a large internal trace memory inside processing element because SDU can communicate to the external memory 3) debugging of applications which are running on multiple processors can facilitate by means of available features inside the proposed trigger mechanism.

Synthesis and Characterization of Poly(ethylene terephthalate) from Biomass-Based Ethylene Glycol: Effects of Miscellaneous Diols (2015)

Using biomass-derived ethylene glycol (bio-EG) to synthesize poly(ethylene terephthalate) (PET) is of notable significance for alleviating the dependence on fossil energy resources. Bio-EG readily contains a small amount of miscellaneous diols, which derive from the side reactions in the catalytic conversion of biomass. To disclose the effects of miscellaneous diols on the synthesis and properties of PET, EG feedstock containing four 1,2-diols, i.e., 1,2-propylene glycol, 1,2-butanediol, 1,2-pentanediol, and 1,2-hexanediol at 0–10% concentrations was used for the synthesis of PET. The molecular weights, intrinsic viscosities, and thermal and mechanical properties of obtained PET materials were measured. It was found that when the overall content of miscellaneous diols in EG was lower than 5%, the molecular weights and thermal properties of the prepared PET materials were very similar to that of PET synthesized from pure EG. The miscellaneous diols were less likely to be incorporated into PET resin because of the steric hindrance of the alkyl group in diols to the esterification and polycondensation reactions. Instead, they preferred to undergo dehydration reactions to form low-boiling-point aldehydes and hemiacetals, which could be removed from the reaction system during the reactions. Three bio-EG samples at purities of 99.9, 98.5, and 95.8 wt % were used for the bio-PET synthesis. Transparent and colorless bio-PET samples were obtained, demonstrating that the presence of miscellaneous diols does not have negative effects on the color quality of PET. The physical properties of bio-PET prepared with bio-EG at a purity of higher than 98 wt % were nearly the same as those of PET derived from pure EG. At a lower bio-EG purity of 95.8 wt %, the tensile strength of the obtained bio-PET sample was slightly decreased. The comprehensive results of property characterization show that bio-PET materials prepared with bio-EG at purity higher than 95 wt % could be used as widely as the conventional petro-PET resin without notable deterioration in their performance.
A Semantic based query expansion to search (2010)

Keyword based information retrieval has difficulties in retrieving relevant information because it is not able to include the semantics of queries. In this paper, we present a novel method for query expansion based on semantic relations. In our proposed algorithm, semantically related words to the query are extracted from WordNet. Valuable words among extracted words are selected as candidate expansion terms. At last candidate terms which do not cause ambiguity and noise in the query are selected as expansion words. This approach is naturally robust to noise words and can improve semantic inferring of information retrieval.
GraphTinker: A High Performance Data Structure for Dynamic Graph Processing (2019)

Interest in high performance analytics for dynamic (constantly evolving) graphs has been on the rise in the last decade, especially due to the prevalence and rapid growth of social networks today. The current state-of-the art data structures for dynamic graph processing rely on the adjacency list model of edge blocks in updating graphs. This model suffers from long probe distances when following edges, leading to poor update throughputs. Furthermore, both current graph processing models-the static model that requires reprocessing the entire graph after every batch update, and the incremental model in which only the affected subset of edges need to be processed-suffer drawbacks. In this paper, we present GraphTinker, a new, more scalable graph data structure for dynamic graphs. It uses a new hashing scheme to reduce probe distance and improve edge-update performance. It also better compacts edge data. These innovations improve performance for graph updates as well as graph analytics. In addition, we present a hybrid engine which improves the performance of dynamic graph processing by automatically selecting the most optimal execution model (static vs. incremental) for every iteration, surpassing the performance of both. Our evaluations of GraphTinker shows a throughput improvement of up to 3.3X compared to the stateof-the-art data structure (STINGER) when used for graph updates. GraphTinker also demonstrates a performance improvement of up to 10X over STINGER when used to run graph analytics algorithms. In addition, our hybrid engine demonstrates up to 2X improvement over the incremental compute model and up to 3X improvement over the static model.
Characterization of Prymnesium Parvum Toxin by Means of Hemolytic Kinetics (1971)

Abstract Rates of hemolysis of rabbit red blood cells induced by prymnesin (a toxin isolated from the euryhaline chrysomonad Prymnesium parvum) are useful for characterizing the activity and properties of this biotoxin. Kinetic data were measured colorimetrically and yielded two pseudo first-order rate constants (k1 and kΨ). The first constant appears to be associated with prolytic processes, and the second with lytic processes. The magnitude of both is related to concentration, though the values of kΨ are more useful for characterization of the hemolytic activity.

Surface Passivation of Semiconductors (1971)

A review is given of the work on the passivation of silicon surfaces with thermally grown silicon dioxide films. This work has led to the high performance and stability of bipolar transistors and insulated gate field-effect transistors used in integrated circuits. The main emphasis is on the processing methods and measurements which have led to the optimization of the passivating properties of silicon dioxide films by controlling fixed charge, interface states, and drift.
Peroxidase/monoclonal antibody conjugates for the study of hemoglobinopathies (1993)

Monoclonal antibodies (mAbs) to normal human hemoglobins (Hbs) A and F and to variant Hbs C and G-Philadelphia were conjugated to horseradish peroxidase (HRP) and used in qualitative or quantitative enzyme-linked immunosorbent assays (ELISAs). Conjugates with output molar HRP/IgG ratios close to 2.0 had higher avidity for the cognate antigens than those with ratios above or below 2.0. The analytical sensitivities of the conjugates ranged from 0.2 to 4 ng of hemolysate containing the target hemoglobin, and it was not related to the input or the output HRP/IgG ratios. The overall imprecision for the qualitative ELISA was below 8%, and the accuracy for the identification of Hbs C and G-Philadelphia was 100% as compared with established methods. Quantitative determinations of HbA based upon direct dose-response curves showed an analytical sensitivity of 1% and an imprecision < or = 11%. The most significant application of the HbA assay was in the differential diagnosis of hemoglobinopathies associated with partial or total suppression of HbA synthesis. Competitive dose-response curves for the HRP/anti-gamma conjugate allowed the quantification of HbF in the clinically significant range of 0.5-10%, with an imprecision < or = 12%. It is concluded that the incorporation of HRP/mAb conjugates into the ELISA technique offers a simpler, more rapid, yet specific alternative for the measurement of hemoglobins.
Hesperidin, an antioxidant flavonoid, prevents acrylonitrile‐induced oxidative stress in rat brain (2008)

Acrylonitrile (ACN) is a volatile, toxic liquid used as a monomer in the manufacture of synthetic rubber, styrene plastics, acrylic fiber, and adhesives. ACN is a potent neurotoxin. A role for free radical mediated lipid peroxidation in the toxicity of ACN has been suggested. We examined the ability of hesperidin, an antioxidant flavonoid, to attenuate ACN-induced alterations in lipid peroxidation in rat brains. The daily oral administration of ACN to male albino rats in a dose of 50 mg/kg bwt for a period of 28 days produced a significant elevation in brain lipid peroxides measured as malondialdehyde (MDA) amounting to 107%, accompanied by a marked decrease in brain-reduced glutathione (GSH) content reaching 63%. In addition, ACN administration resulted in significant reductions in the enzymatic antioxidant parameters of brain; superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), and glutathione-S-transferase (GST) recording 43%, 64%, 52%, and 43%, respectively. On the other hand, pretreatment with hesperidin and its coadministration with ACN once daily in a dose of 200 mg/kg bwt i.p. for 28 days ameliorated ACN-induced alterations in brain lipid peroxidation. These results suggest that hesperidin may have a beneficial role against ACN-induced oxidative stress in the brain; an effect that is mainly attributed to the antioxidant property of hesperidin.
