Distributed trajectory similarity search (2017)

Mobile and sensing devices have already become ubiquitous. They have made tracking moving objects an easy task. As a result, mobile applications like Uber and many IoT projects have generated massive amounts of trajectory data that can no longer be processed by a single machine efficiently. Among the typical query operations over trajectories, similarity search is a common yet expensive operator in querying trajectory data. It is useful for applications in different domains such as traffic and transportation optimizations, weather forecast and modeling, and sports analytics. It is also a fundamental operator for many important mining operations such as clustering and classification of trajectories. In this paper, we propose a distributed query framework to process trajectory similarity search over a large set of trajectories. We have implemented the proposed framework in Spark, a popular distributed data processing engine, by carefully considering different design choices. Our query framework supports both the Hausdorff distance the Fréchet distance. Extensive experiments have demonstrated the excellent scalability and query efficiency achieved by our design, compared to other methods and design alternatives.

Formation of vanadium silicides by the interactions of V with bare and oxidized Si wafers (1973)

Formation of vanadium silicides by the interactions of vanadium with bare and oxidized Si wafers has been studied by both x-ray diffraction and He ion backscattering techniques. X-ray diffraction was used to identify phases and ion backscattering to profile compositional changes. In the case of V on Si, the silicide VSi2, which is a silicon-rich phase, was found to form at temperatures from 600 to 1000 °C. In the case of V on SiO2, reactions took place only at temperatures above 800 °C, and the reaction products were identified to be V3Si, V5SI3, and V2O5. Both V3Si and V5Si3 are vandium-rich phases, and the V3Si that we found was a continuous layer between the substrate and the other two phases, and became superconducting at about 15 °K.
Using complex networks towards information retrieval and diagnostics in multidimensional imaging (2015)

We present a fresh and broad yet simple approach towards information retrieval in general and diagnostics in particular by applying the theory of complex networks on multidimensional, dynamic images. We demonstrate a successful use of our method with the time series generated from high content thermal imaging videos of patients suffering from the aqueous deficient dry eye (ADDE) disease. Remarkably, network analyses of thermal imaging time series of contact lens users and patients upon whom Laser-Assisted in situ Keratomileusis (Lasik) surgery has been conducted, exhibit pronounced similarity with results obtained from ADDE patients. We also propose a general framework for the transformation of multidimensional images to networks for futuristic biometry. Our approach is general and scalable to other fluctuation-based devices where network parameters derived from fluctuations, act as effective discriminators and diagnostic markers.
Decreased insulin activation of glycogen synthase in skeletal muscles in young nonobese Caucasian first-degree relatives of patients with non-insulin-dependent diabetes mellitus. (1992)

Insulin resistance in non-insulin-dependent diabetes is associated with a defective insulin activation of the enzyme glycogen synthase in skeletal muscles. To investigate whether this may be a primary defect, we studied 20 young (25 +/- 1 yr) Caucasian first-degree relatives (children) of patients with non-insulin-dependent diabetes, and 20 matched controls without a family history of diabetes. Relatives and controls had a normal oral glucose tolerance, and were studied by means of the euglycemic hyperinsulinemic clamp technique, which included performance of indirect calorimetry and muscle biopsies. Insulin-stimulated glucose disposal was decreased in the relatives (9.2 +/- 0.6 vs 11.5 +/- 0.5 mg/kg fat-free mass per (FFM) min, P less than 0.02), and was due to a decreased rate of insulin-stimulated nonoxidative glucose metabolism (5.0 +/- 0.5 vs 7.5 +/- 0.4 mg/kg fat-free mass per min, P less than 0.001). The insulin-stimulated, fractional glycogen synthase activity (0.1/10 mmol liter glucose-6-phosphate) was decreased in the relatives (46.9 +/- 2.3 vs 56.4 +/- 3.2%, P less than 0.01), and there was a significant correlation between insulin-stimulated, fractional glycogen synthase activity and nonoxidative glucose metabolism in relatives (r = 0.76, P less than 0.001) and controls (r = 0.63, P less than 0.01). Furthermore, the insulin-stimulated increase in muscle glycogen content over basal values was lower in the relatives (13 +/- 25 vs 46 +/- 9 mmol/kg dry wt, P = 0.05). We conclude that the defect in insulin activation of muscle glycogen synthase may be a primary, possibly genetically determined, defect that contributes to the development of non-insulin-dependent diabetes.
Anti–GM-CSF Autoantibodies in Patients with Cryptococcal Meningitis (2013)

Cryptococcal meningitis has been described in immunocompromised patients, as well as in those for whom no immune defect has been identified. GM-CSF regulates the function of phagocytes and pulmonary alveolar macrophages, critical elements in cryptococcal control. We performed clinical histories, immunological evaluation, and anticytokine autoantibody screening in four current patients with cryptococcal meningitis and identified and tested 103 archived plasma/cerebrospinal fluid samples from patients with cryptococcal meningitis. We assessed the ability of anti-GM-CSF autoantibody-containing plasmas to inhibit GM-CSF signaling. We recognized anti-GM-CSF autoantibodies in an otherwise healthy female with cryptococcal meningitis who later developed pulmonary alveolar proteinosis (PAP). Her diagnosis prompted screening of patients with cryptococcal meningitis for anticytokine autoantibodies. We identified seven HIV-negative patients with cryptococcal meningitis who tested positive for high-titer anti-GM-CSF autoantibodies. Two of the seven later developed evidence of PAP. Plasma from all patients prevented GM-CSF-induced STAT5 phosphorylation and MIP-1α production in normal PBMCs. This effect was limited to their IgG fraction. Anti-GM-CSF autoantibodies are associated with some cases of cryptococcal meningitis in otherwise immunocompetent patients. These cases need not have associated PAP.
A Highly Efficient Sulfur-Catalyzed Oxidative Carbonylation of Primary Amines and β-Amino Alcohols (2006)

A highly efficient sulfur-catalyzed oxidative carbonyl­ation of aliphatic amines and aliphatic β-amino alcohols to ureas and 2-oxazolidinones, respectively, was developed. Sodium nitrite was involved in the reoxidation of hydrogen sulfide to sulfur in the ­catalytic oxidative carbonylation cycle.
Alginate as a macroaffinity ligand and an additive for enhanced activity and thermostability of lipases (2001)

Lipases are being employed increasingly for the synthesis of drug intermediates and pharmaceutically important molecules as well as for the resolution of racemic mixtures for obtaining physiologically active enantiomers. Alginate was used as a macroaffinity ligand to purify lipases from Chromobacterium viscosum, porcine pancreas and wheatgerm by employing the technique of affinity precipitation. In all the cases, the purified preparation showed a single band on SDS/PAGE. The process gave adequate yields of 87, 75 and 62% in the case of Chromobacterium, porcine and wheatgerm lipases respectively. Alginate was also found to activate the enzymes; this effect was most dramatic in the case of wheatgerm lipase, for which a 4-5-fold activity increase was observed. Furthermore, alginate was also found to protect the enzyme against thermoinactivation.
The sylvanshine: retroreflection from dew-covered trees (1994)

Some dew-covered plants are strongly retroreflective. The bright glow seen when the antisolar point falls on grass is known as the heiligenschein. Its widely accepted explanation requires that the grass be covered with hair. The discovery of the sylvanshine, a closely related phenomenon best seen at night, revealed that strong retroreflection can occur on hairless dew-covered plants. A simple model shows that below a contact angle of 90°, the enhancement in the backscatter direction is virtually identical to that given by a diffusely reflecting surface, but as the contact angle climbs to 140°, enhancement increases by 2 orders of magnitude. Plants that exhibit such large contact angles are not the norm, but can be found chiefly among coniferous trees, a few of which display the sylvanshine with great brilliance.
STATCOM Impact Study on the Integration of a Large Wind Farm into a Weak Loop Power System (2008)

Recently, renewable wind energy is enjoying a rapid growth globally to become an important green electricity source to replace polluting and exhausting fossil fuel. However, with wind being an uncontrollable resource and the nature of distributed wind induction generators, integrating a large-scale wind-farm into a power system poses challenges, particularly in a weak power system. In the paper, the impact of static synchronous compensator (STATCOM) to facilitate the integration of a large wind farm (WF) into a weak power system is studied. First, an actual weak power system with two nearby large WFs is introduced. Based on the field SCADA data analysis, the power quality issues are highlighted and a centralized STATCOM is proposed to solve them, particularly the short-term (seconds to minutes) voltage fluctuations. Second, a model of the system, WF, and STATCOM for steady state and dynamic impact study is presented, and the model is validated by comparing with the actual field data. Using simulated PV and QV curves, voltage control and stability issues are analyzed, and the size and location of STATCOM are assessed. Finally, a STATCOM control strategy for voltage fluctuation suppression is presented and dynamic simulations verify the performance of proposed STATCOM and its control strategy.

Input impedance and mutual coupling of conformal patch array on multilayer cylinder (2000)

The effect of dielectric overlay and of the curvature on radiation properties, on the mutual coupling and on the input impedance is analyzed in this paper for the case of rectangular probe-fed patches on a circular cylinder geometry. The circular cylinder is assumed to be infinite in the axial direction and the spectral domain Green's functions technique together with the moment method has been used to evaluate the unknown current distribution induced by the probe on the patches. Input impedance and mutual coupling for different design of the patches embedded in a dielectric substrate has been tested against published results. The radiation pattern of a four-by-four patch array is also calculated, taking into account the mutual coupling, and verified against measured results. For this case the active impedance of the patches is calculated for the working condition of the antenna when all the ports of the array are fed simultaneously.

Current effective topical therapies in the management of psoriasis. (2011)

Topical therapy forms the cornerstone of treatment in the management of psoriasis. It plays a significant role as monotherapy in mild to moderate psoriasis, and it is used predominantly as adjunctive therapy in moderate to severe forms of the disease. Over the past decade, the topical treatment of psoriasis has evolved from the age-old applications, such as coal tar, to the more cosmetically acceptable and efficacious options containing topical corticosteroids, vitamin D analogues, and combined agents. With the advent of topical therapies in tailored vehicles and sophisticated delivery modes, the outlook for effectively managing psoriasis with topical approaches appears promising. To ensure therapeutic success, patient education about the disease, treatment options, proper administration, and adverse effects is essential, which will alleviate the common problem of poor patient adherence and promote more optimal clinical outcomes.
Efficacy of Bioactive Compounds of Sponges to Prevent Biofilm Formation on Medical Implants (2013)

Bacterial biofilms are surface-attached communities of microorganisms that are protected by an extracellular matrix of biomolecules. In the biofilm state, bacteria are significantly more resistant to external assault, including attack by antibiotics. In their native environment, bacterial biofilms underpin costly biofouling that wreaks havoc on shipping, utilities, and offshore industry. Within a host environment, they are insensitive to antiseptics and basic host immune responses. It is estimated that up to 80% of all microbial infections are biofilm-based. Biofilm infections of indwelling medical devices are of particular concern, since once the device is colonized, infection is almost impossible to eliminate. Importantly, we discuss several sets of compounds derived from marine sponges that we are developing in our labs to address the persistent biofilm problem. Marine bioactive compound synthesis of natural products and their analogues-including our marine sponge-derived compounds and initial adjuvant activity and toxicological screening of our novel anti-biofilm compounds.

Large Plastic Scintillators for Radioactivity Measurement (1961)

This study of counting systems utilizing large plastic scintillators includes an investigation of the component parts, the γ-ray spectra obtained from large scintillators, and the application of large scintillators to total-body and low-level sample counting. Properties of the component parts investigated were: (1) light production from plastic scintillators of different manufacture; (2) the influence of crystal size and shape on light collection efficiency; and (3) the photocathode response of 5-in. and 16-in. photomultiplier tubes. Experimental spectra taken with a 16-in. diameter by 8-in. thick cylinder of plastic are shown and the results for 0.662 MeV γ-rays compared to a calculated (Monte Carlo) pulse-height distribution. The application of large plastic scintillators to total-body counting is evaluated by comparing the response of an array of 16-in. by 8-in, plastic scintillators to a single 8-in. by 4-in. NaI detector. Spectra taken with an 18-in. by 18-in. plastic well counter are presented, and data is presented on the performance of this device as a low-level sample counter.
On query formulation in information retrieval (1981)

Various schemes of query formulation in information retrieval are analyzed. The frequency characteristics of terms in the documents of a collection have long been used as indicators of term importance for indexing purposes. In particular, very rare or very frequent terms are normally believed to be less effective than the medium frequency terms. Accordingly, it has been suggested that query term weights should first increase and then decrease as the document frequencies of the query terms increase. Three term weighting models (utility weights, precision weights, and discrimination value weights) are studied and they all substantiate the suggested behavior. A fourth scheme, the inverse document frequency system, is shown to be a close approximation of the precision system under certain circumstances.
Two of the three models require relevance information. The precision and utility weights are based on the occurrence characteristics of the terms in the relevant, as opposed to the nonrelevant, documents in the collection. Methods are suggested for estimating the relevant properties of the terms based on the overall occurrence characteristics in the collection. Empirical evaluation results are shown comparing the weighting systems using the term relevance properties with the more conventional frequency-based methodologies. Experimental evidence indicates that relevance feedback is a most promising strategy.
The last part of the thesis demonstrates the advantages and disadvantages of the Boolean and vector representations of queries. A more general framework which encompasses both the fuzzy set approach and the vector space approach is outlined. The new scheme is derived from the concept of p-norms. It is shown that the fuzzy set approach is the extreme case when p = (INFIN) while the vector space approach represents the other extreme case when p = 1.
Purification and Characterization of Banana Bunchy Top Virus (1990)

Abstract Banana bunchy top virus (BBTV) was successfully purified by a procedure which included pulverizing diseased tissues frozen in liquid nitrogen, clarification of the extract with chloroformbutanol, concentration of the virus by cycles of differential centrifugation, stirring and incubating at 4°C followed by a second cycle of differential centrifugation and sucrose density gradient centrifugation. The concentrations of BBTV obtained from leaf blades and midribs plus petioles were up to 0.34 and 0.56mg/kg tissue, respectively. The virus concentration was highest in diseased leaves collected from October to December, and lowest in those collected from June to September. BBTV is a luteovirus (particles 20– 22 nm in diameter), preparations of which have maximum absorbance at 257 nm, minimum absorbance at 240 nm and a A260/280 ratio of 1.46. The relative molecular mass (M r ) of BBTV coat protein subunit is 21,000, and that of its ssRNA is 2.0 × 10 6 .

High-coercivity Nd-Fe-B-type permanent magnets with less dysprosium (1990)

The effects of V or Mo addition on the microstructure and magnetic properties of Nd-Dy-Fe-Co-B sintered magnets were studied experimentally. It is shown that these additives increase the intrinsic coercivity of cobalt-containing Nd-Fe-B-type sintered magnets, serving to reduce the amount of Dy required for thermal stability. Corrosion resistance in a humid atmosphere is also improved by these elements. It is concluded that V or Mo addition in sintered magnets make it possible to achieve the thermal stability and corrosion resistance required in applications which encounter high-temperature and high-humidity environments and in which a high remanence is of secondary importance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
An Immunodominant, Cross-Reactive B-Cell Epitope Region Is Located at the C-Terminal Part of the Hamster Polyomavirus Major Capsid Protein VP1 (2000)

The VP1 represents the major capsid protein of the hamster polyomavirus (HaPV). Here we describe the mapping of epitopes along the VP1 using Escherichia coli-expressed VP1-dihydrofolate reductase (DHFR) fusion proteins and PepScan analysis. By use of DHFR fusion proteins an immunodominant region was localized in the C-terminal part of VP1 between amino acids 320-384. Further epitopes are located in the regions amino acids 1-133 and amino acids 133-320, respectively. There were no obvious differences in the reactivity between sera of tumor-bearing and papilloma-free naturally HaPV-infected hamsters. In contrast, PepScan analysis revealed linear epitopes in the regions amino acids 79-97 and amino acids 353-367 for tumor-bearing animals and amino acids 101-113 and amino acids 165-179 for papilloma-free animals. The region between amino acids 320-384 of HaPV-VP1 was found to be involved in cross-reactivity of VP1 from HaPV and other polyomaviruses. Previously we have demonstrated that heterologous expression of HaPV-VP1 allowed the formation of virus-like particles (VLPs). From epitope mapping data and structural predictions it has been suggested that HaPV-VP1-VLPs may tolerate foreign peptides in the region amino acids 81-88 and the C-terminal part of VP1.
A Peptide Antagonist Disrupts NK Cell Inhibitory Synapse Formation (2013)

Productive engagement of MHC class I by inhibitory NK cell receptors depends on the peptide bound by the MHC class I molecule. Peptide:MHC complexes that bind weakly to killer cell Ig-like receptors (KIRs) can antagonize the inhibition mediated by high-affinity peptide:MHC complexes and cause NK cell activation. We show that low-affinity peptide:MHC complexes stall inhibitory signaling at the step of Src homology protein tyrosine phosphatase 1 recruitment and do not go on to form the KIR microclusters induced by high-affinity peptide:MHC, which are associated with Vav dephosphorylation and downstream signaling. Furthermore, the low-affinity peptide:MHC complexes prevented the formation of KIR microclusters by high-affinity peptide:MHC. Thus, peptide antagonism of NK cells is an active phenomenon of inhibitory synapse disruption.
