Feature Selection for Automatic Classification of Non-Gaussian Data (1987)

A computer-based technique for automatic selection of features for the classification of non-Gaussian data is presented. The selection technique exploits interactive cluster finding and a modified branch and bound optimization of piecewise linear classifiers. The technique first finds an efficient set of pairs of oppositely classified clusters to represent the data. Then a zero-one implicit enumeration implements a branch and bound search for a good subset of features. A test of the feature selection technique on multidimensional synthetic and real data yielded close-to-optimum, and in many cases optimum, subsets of features. The real data consisted of a) 1284 12-dimensional feature vectors representing normal and abnormal breast tissue, extracted from X-ray mammograms, and b) 1060 30-dimensional feature vectors representing tanks and clutter in infrared video images.
Client's Script Execution in Semantic Web Services (2006)

This paper presents a new method of Web services development that allows the execution of client-defined scripts on the server side. The new system architecture and features are implemented as an ontology server for the CancerGrid project. The authors believe that there will be broad applicability of the proposed method for future Web services
Genetic Tests of the Roles of the Embryonic Ureases of Soybean (1991)

We assayed the in vivo activity of the ureases of soybean (Glycine max) embryos by genetically eliminating the abundant embryo-specific urease, the ubiquitous urease, or a background urease. Mutant embryos accumulated urea (250-fold over progenitor) only when lacking all three ureases and only when developed on plants lacking the ubiquitous urease. Thus, embryo urea is generated in maternal tissue where its accumulation is not mitigated by the background urease. However, the background urease can hydrolyze virtually all urea delivered to the developing embryo. Radicles of 2-day-old germinants accumulated urea in the presence or absence of the embryo-specific urease (2 micromoles per gram dry weight radicle). However, mutants lacking the ubiquitous urease exhibited increased accumulation of urea (to 4-5 micromoles urea per gram dry weight radicle). Thus, the ubiquitous and not the embryo-specific urease hydrolyzes urea generated during germination. In the absence of both of these ureases, the background urease activity (4% of ubiquitous urease) may hydrolyze most of the urea generated. A pleiotropic mutant lacking all urease accumulated 34 micromoles urea per gram dry weight radicle (increasing 2.5-fold at 3 days after germination). Urea (20 millimolar) was toxic to in vitro-cultured cotyledons which contained active embryo-specific urease. Cotyledons lacking the embryo-specific urease accumulated more protein when grown with urea than with no nitrogen source. Among cotyledons lacking the embryo-specific urease, fresh weight increases were virtually unchanged whether grown on urea or on no nitrogen and whether in the presence or absence of the ubiquitous urease. However, elimination of the ubiquitous urease reduced protein deposition on urea-N, and elimination of both the ubiquitous and background ureases further reduced urea-derived protein. The evidence is consistent with the lack of a role in urea hydrolysis for the embryo-specific urease in developing embryos or germinating seeds. Because the embryo-specific urease is deleterious to cotyledons cultured in vitro on urea-N, its role may be to hydrolyze urea in wounded or infected embryos, creating a hostile environment for pest or pathogen. While the ubiquitous urease is operative in leaves and in seedlings, all or most of its function can be assumed by the background urease in embryos and in seedlings.
Computation of accurate interconnect process parameter values for performance corners under process variations (2006)

This paper introduces a fast analytical model for determining accurate parasitic values for best- and worst-case delays of a stage under interconnect process variations. The inputs to the model are the nominal values for each interconnect and device parameter and the amount of variation in each interconnect parameter. The outputs of the model are the interconnect parameter dimensions within the range of process variation that yield the best- and worst-case delay of a stage. Simulations show that our model accurately predicts the performance corners of a stage while those predicted by traditional best/worst-case analysis methodologies can have an error of up to 28.42%.
Indomethacin Inhibits Bone Resorption and Lysosomal Enzyme Release from Bone in Organ Culture (1980)

The effect of indomethacin on bone resorption was studied in an organ culture system, using calvarial bones from 6--7-day-old mice. It was found that indomethacin inhibited spontaneous bone resorption, as estimated by decreased release of 45Ca, Ca2+ and Pi. Indomethacin reduced the release of beta-glucuronidase, beta-galactosidase and beta-N-acetylglucosaminidase, diminished glucose consumption and lactate production, but showed no effect on the release of lactate dehydrogenase. No inhibitory effect of indomethacin on the release of 45Ca stimulated by parathyroid hormone, prostaglandin E2 or 1 alpha(OH)D3 could be registered. 5,8,11,14-eicosatetraynoic acid, an inhibitor of both cyclo- and lipoxygenase pathway of arachidonate metabolism, reduced the spontaneous release of 45Ca, whereas the selective lipoxygenase inhibitor 5,8,11-eicosatriynoic acid was without effect. The results presented indicate that indomethacin may have an inhibitory effect upon the osteoclasts, probably by decreased metabolism of arachidonic acid via the cyclo-oxygenase pathway. A possible relationship between this finding and the pathogenesis of rapid destruction of articular bone in osteoarthritic patients treated with indomethacin is discussed.
Review on UHF RFID Localization Methods (2019)

With the wide spread of the Internet of Things (IoT), wireless localization technology has provided various location-based applications and services. Radio frequency identification (RFID) has been widely used in objects' identification and tracking. Combining with its excellent identification ability, RFID is also a promising technique for indoor localization. This paper provides the state-of-the-art of UHF RFID localization and gives an introduction of methods and applications. The major methods of UHF RFID localization have two types: 1) range-based and 2) range-free, reported in previous literature. The range-based methods obtain the distance or angle between the antenna and tag utilizing the received signal strength indicator (RSSI), time information or signal phase and estimate tag location further combining the scheme geometrical characteristics. The methods based on fingerprinting and non-fingerprinting are mainly discussed in the range-free domain. Finally, a comparative study of these surveyed works are presented and concluded with a future trend.

Molecular and Phenotypic Analysis of the CS54 Island of<i>Salmonella enterica</i>Serotype Typhimurium: Identification of Intestinal Colonization and Persistence Determinants (2003)

The shdA gene is carried on a 25-kb genetic island at centisome 54 (CS54 island) of the Salmonella enterica serotype Typhimurium chromosome. In addition to shdA, the CS54 island of Salmonella serotype Typhimurium strain LT2 contains four open reading frames designated ratA, ratB, sivI, and sivH. DNA hybridization analysis revealed that the CS54 island is comprised of two regions with distinct phylogenetic distribution within the genus Salmonella. Homologues of shdA and ratB were detected only in serotypes of Salmonella enterica subsp. I. In contrast, sequences hybridizing with ratA, sivI, and sivH were present in S. enterica subsp. II and S. bongori in addition to S. enterica subsp. I. Deletion of the ratA and sivI genes did not alter the ability of Salmonella serotype Typhimurium to colonize the organs of mice. Insertional inactivation of the sivH gene resulted in defective colonization of the Peyer's patches of the terminal ileum but normal colonization of the cecum, mesenteric lymph nodes, and spleen. Deletion of the shdA gene resulted in decreased colonization of the cecum and Peyer's patches of the terminal ileum and colonization to a lesser degree in the mesenteric lymph nodes and spleen 5 days post-oral inoculation of mice. A strain containing a deletion in the ratB gene exhibited a defect for the colonization of the cecum but not of the Peyer's patches, mesenteric lymph nodes, and spleen. The shdA and ratB deletion strains exhibited a shedding defect in mice, whereas the sivH deletion strain was shed at numbers similar to the wild type. These data suggest that colonization of the murine cecum is required for efficient fecal shedding in mice.
Generation of therapeutic antibody responses against IgE through vaccination (2002)

IgE is the central mediator in atopic allergies such as hay fever, eczema, and asthma; therefore, it is a prime target in the development of allergen-independent preventive treatments. We describe an active immunization strategy that has the potential to reduce IgE to a clinically significant extent. The active vaccine component is a chimeric IgE molecule, Cepsilon2-Cepsilon3-Cepsilon4. The receptor-binding target domain, Cepsilon3, is derived from the recipient species, whereas the flanking domains, Cepsilon2 and Cepsilon4, are derived from an evolutionarily distant mammal. The flanking domains have dual functions, acting both as structural support for the Cepsilon3 domain and to break T cell tolerance by providing foreign T cell epitopes. The efficacy of the vaccine was studied in an ovalbumin-sensitized rat model. Vaccination resulted in antibody responses against IgE in all rats and in a substantial reduction in serum IgE levels in three out of four strains. The skin reactivity upon allergen challenge was significantly reduced in vaccinated animals. The vaccine appears to be safe to use as an antigen. No cross-linking activity was observed in sera of vaccinated animals, and the response to vaccination was reversible with time. Our results suggest that active immunization against IgE has the potential to become a therapeutic method for humans.
High-Dimensional Chaotic Dynamics of an External Cavity Semiconductor Laser (1994)

We report experimental realization of high-dimensional chaos in a semiconductor laser with delayed feedback from a T-shaped cavity. We study the transition phenomena from regular to high-dimensional chaotic behavior and analyze the time series quantitatively. Correlation dimensions up to ${C}_{2}\ensuremath{\simeq}7$ are determined reliably from experimental data by a combination of a singular value analysis and a Grassberger-Procaccia algorithm. Modeling the dynamical behavior using semiclassical delay rate equations provides a basic understanding of the observed delay-induced instabilities.
Molding process development for Low-Cost MEMS-WLCSP with silicon pillars and Cu wires as vertical interconnections (2017)

As the MEMS (Micro-Electro-Mechanical Systems) devices head towards smaller form factor and greater functionalities, improvement in WLCSP (Wafer Level Chip Scale Package) technology is necessary to meet the new requirements from today's electronic devices. TSV (Through Silicon Via) technology has always been used as the vertical interconnections for assembly of MEMS-WLCSP packaging. In our development work, we proposed to use an innovative approach to substitute the TSV with TMV (Through Mold Via), using the wafer-level over-molding of vertical Si (silicon) pillars and Cu (copper) wires as vertical interconnections. For the molding process development work, epoxy mold compound (EMC) and silicone mold compound (SMC) materials were studied to explore suitable mold material candidates for good wafer warpage control and void free vertical interconnects structure mold filling. Fine filler (EMC) B and (EMC) C molded to a thin over-mold cap of 150μm gave void free mold fill and the best wafer warpage control for subsequent Cu (cooper) redistributed layers (RDL)s processing. Liquid (EMC) B was observed to be more suitable for encapsulating vertical wires than granular (EMC) C as random wires collapse was observed after the molding process. Greater Cu smearing on the exposed Cu wire interconnections was observed on (EMC) C as compared to (EMC) B after the mold cap was back-grinded to expose the vertical interconnects. Greater Cu smearing could be attributed to the lower modulus for (EMC) C, which resulted in greater galling after back-grinding and greater Cu smearing. In conclusion, the (SMC) candidates have good wafer warpage control, but were not suitable for our MEMS-WLCSP process flow due to void presence in (SMC) D and flattening of wires for (SMC) E. Hence, (EMC) B and (EMC) C were shortlisted for actual wafers molding development.
Open IPTV convergence service creation and management using service delivery platform (2015)

IPTV brought a new digital era in the broadcasting domain. The main change of digital broadcasting is an advent of a bi-directional interactive service feature. Using that bi-directionality, IPTV provides various kinds of convergence service such as information providing, advertisement, and e-commerce. But the number of services required to be developed and to be provided to users geometrically increases and the lifetime of services is shortened requiring services to be developed within a short period. To support the market demand for a massive service delivery, the IPTV platform based on service delivery platform (SDP) is essential. The SDP is a technique developed to meet the variation in communication and information technology convergence environments, allows service providers to rapidly create and deliver convergence services. This paper describes an Open IPTV service delivery platform structure and method for supporting rapid service creation by reusing pre-defined IPTV service components. We describe key components and functionalities of SDP, IPTV Enablers and its combination for service convergence. We show customer targeted mobile advertisement for Open IPTV convergence service example.
Effect of node size on the performance of cache-conscious B <sup>+</sup> -trees (2003)

In main-memory databases, the number of processor cache misses has a critical impact on the performance of the system. Cache-conscious indices are designed to improve performance by reducing the number of processor cache misses that are incurred during a search operation. Conventional wisdom suggests that the index's node size should be equal to the cache line size in order to minimize the number of cache misses and improve performance. As we show in this paper, this design choice ignores additional effects, such as the number of instructions executed and the number of TLB misses, which play a significant role in determining the overall performance. To capture the impact of node size on the performance of a cache-conscious B+ tree (CSB+-tree), we first develop an analytical model based on the fundamental components of the search process. This model is then validated with an actual implementation, demonstrating that the model is accurate. Both the analytical model and experiments confirm that using node sizes much larger than the cache line size can result in better search performance for the CSB+-tree.
Double Sided Cooled Module concept for High Power Density in HEV Applications (2015)

Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV) are expected to be produced and commercialized at a large scale in the coming years. This requires the integration of an electric drive train into a large number of car platforms under massive space and cost constraints. We present a novel power module concept with double sided chip cooling which allows very high power densities. In addition, lower stray inductance and package resistance improvements enable high inverter efficiencies.

Confirmation and Control of a Paraquat-Tolerant Goosegrass (Eleusine indica) Biotype<sup>1</sup> (2002)

Diminished control of goosegrass was observed in tomato fields located in Manatee County, FL, after years of repeated paraquat use. Tolerance of the Manatee biotype to paraquat was confirmed by its comparison in greenhouse studies with a susceptible biotype from the Alachua County, FL. A 30-fold increase in paraquat rate was required to reach the 50% growth reduction level of the resistant biotype over the susceptible biotype. The Manatee biotype was not tolerant to clethodim, metribuzin, or sethoxydim. These herbicides provided adequate control of all the goosegrass biotypes tested.Nomenclature: Clethodim; metribuzin; paraquat; sethoxydim; goosegrass, Eleusine indica L. #3 ELEIN; tomato, Lycopersicou esculentum Mill.Additional index words: Additive, antagonism, herbicide resistance, synergism.Abbreviations: GR50, herbicide concentration required to inhibit goosegrass aboveground biomass by 50%; WAT, weeks after treatment.
True Ground Speed Measurement Techniques (1982)

<div class="htmlview paragraph">This paper considers alternative methods for measuring the true ground speed of tractor vehicles as a means for controlling wheel slip to improve traction efficiency and reduce vehicle and tire wear. Test data are presented on the slip of both driven and undriven wheels for a tractor operating under various speed, load, and soil conditions. Data from a “fifth wheel” operating on smoothed and compacted soil behind a draft sled also is included. Vehicle speed determined from the speed of undriven wheels as well as vehicle speed derived from driven (slipping) wheels using a number of data processing strategies is not sufficiently accurate for either vehicle monitoring or closed loop control.</div> <div class="htmlview paragraph">The errors of single and dual beam doppler radar speed sensors caused by vehicle motion are analyzed. Single beam radar systems are shown to operate with an accuracy acceptable for operator control using signal integration times greater than approximately one second. The dual beam radar system exhibits better accuracy by eliminating the effect of quasi steady state offsets of vehicle pitch, roll, and yaw. Nevertheless, the rates of change of these angles still result in spreading the doppler return spectrum again requiring filtering or averaging to obtain an estimate of ground speed.</div>

Digital campus innovation project: integration of building information modelling with building performance simulation and building diagnostics (2015)

Building Information Modelling (BIM) has emerged as a powerful technology that creates a central hub for managing building energy and resources at all phases of the building life cycle. Without it, many tools that lack interoperability are used, thus massively under-exploiting the efforts of other building design and management parties; this largely describes the status quo. However, despite the power of BIM, it has not been readily adopted by industry, and especially not at the community and campus scale. Digital Campus Innovation (DCI) is a large multi-year and multidisciplinary project involving development of a methodology for use of BIM for operation and maintenance of a portion of Carleton University's 45 interconnected buildings. Major elements include: (1) development of highly-detailed BIM models for site and buildings; (2) conversion from BIM models to building performance simulation (BPS) models; (3) model validation using measured data; (4) building Fault Detection and Diagnostics (FDD) using advanced algorithms and calibrated modelling; and (5) advanced building performance data visualization on top of 3D BIM model. This paper will describe the methodologies that are being developed while demonstrating the ongoing processes by a case study of Canal Building, a part of DCI project. While the project is only one year old, impactful examples have already demonstrated BIM as an invaluable technology that improves indoor environment quality, reduces energy costs, and has a potential application for asset management.
New Nanocomposite Materials Reinforced with Cellulose Whiskers in Atactic Polypropylene:  Effect of Surface and Dispersion Characteristics (2005)

New nanocomposite films were prepared with atactic polypropylene as the matrix and either of three types of cellulose whiskers, with various surface and dispersion characteristics, as the reinforcing phase: aggregated without surface modification, aggregated and grafted with maleated polypropylene or individualized and finely dispersed with a surfactant. Films obtained by solvent casting from toluene were investigated by means of scanning electron microscopy, dynamic mechanical analysis, and tensile testing. In the linear region, the mechanical properties above the glass-rubber transition were found to be drastically enhanced for the nanocomposites as compared to the neat polypropylene matrix. These effects were ascribed to the formation of a rigid network with filler/filler interactions. In addition, interactions between the filler and the matrix as well as the dispersion quality were found to play a major role on the mechanical properties of the composites when investigation of the films was performed in the nonlinear region.
The monounsaturated acyl‐ and alkyl‐moieties of wax esters and their distribution in commercial orange roughy (<i>Hoplostethus atlanticus</i>) oil (1985)

Wax esters were isolated from commercial orange roughy (Hoplostethus atlanticus) oil by column chromatography and fractionated by argentation thin layer chromatography. Following transesterification, the resultant fatty acid methyl esters and fatty alcohols were analyzed by gas chromatography. Both acyl- and alkyl-moieties were mainly of the monoene structure within the 16:1-22:1 range. After derivatization, the positions of the double bonds of even numbered fatty acid and fatty alcohol isomers were located by chromatography-mass spectrometry and compared. Results of these positional analyses indicate that the primary desaturation reactions takes place in the delta 9 position of pre-existing (C14 to C24) acyl chains. It is proposed that acyl components from 18:1 are subjected to chain elongation to form a mixture of 24:1 isomers as the final product. Apart from the 24:1 acyl moiety of the wax esters, in which the double bond was almost exclusively in the delta 15 position, de novo biosynthetic reactions on acids and alcohols appear to yield related acyl- and alkyl-moieties of resynthesized wax esters.
