Analysis of 2540 dpi Dot Reproduction by Liquid Development (2004)

High-resolution liquid development process was examined theoretically and experimentally. Recently, we have realized extremely high-resolution (2540 dpi) images on a liquid toner developing system. The mechanisms of reproducing such extremely high resolution are investigated from the viewpoint of the developing process. An electric potential distribution in a single-dot latent image on a photoreceptor is calculated from the exposure energy of high-resolution Laser Scanning Unit (LSU) and surface properties of a photoreceptor. The development characteristics of single-dot images are investigated using numerical simulations of twodimensional continuity equations based on the electrostatic forces in the development, taking account of the motion of both toner particles and counter ions. The simulation shows that, at an early stage of the development, the toner particles are developed around the edge of the latent image on the photoreceptor, and then the particles are accumulated to form a single dot with horizontal migration toward the center of the latent image. Such developing behavior is characteristic of liquid toner, and the result suggests the mechanism of the high reproducibility of liquid development.

Combining Analysis of Different Performances Through the Use of Dimensional Analysis (2007)

This article demonstrates that it is possible and valuable to develop a generic evaluation approach for preliminary design based on dimensional analysis and a method for multiple evaluations of heterogeneous performances. The use of dimensional analysis theory allows building a minimal number of aggregate indicators based on the adequate combination of elementary performance variables of the same type. The proposed method is particularly convenient during the preliminary design stage. The reason for using dimensional analysis for early design purpose is that it is strongly based on concepts of similarity and analogy and that analogical reasoning has been proved to play a central role in design contexts. Mathematically, similarity refers to a transformation of variables that leads to a reduction in the number of independent variables that specify a problem. In addition, we argue that dimensional analysis can be integrated in the existing theoretical framework of design (i.e. General Design Theory). We have applied the approach to a case study of the design of a workplace by taking into consideration, for simplification purposes of this article, only two requirements: improving the visual comfort of the occupants and reducing the energy consumption level. This approach may be used in many design contexts in providing a fruitful framework to structure performances and evaluation stage.
TMO-structured cluster-based real-time management of location data on massive volume of moving items (2004)

A major challenge in the field of location based service (LBS) system engineering, is to establish a highly scalable system architecture which can be instantiated in moderate-size configurations handling thousands of moving items as well as in upper-end configurations handling millions of moving items. We are exploring an approach of using a cluster of database server nodes and effecting efficient distributed and parallel computing in both real-time update of location records of moving items and processing of location-related queries. The approach of developing efficient middleware which is layered on a cluster of nodes running commercial off-the-shelf database servers, has been adopted. The middleware design is substantially based on the TMO scheme for real-time distributed object programming and real-time distributed computing system design, which enables low-overhead coordination of distributed computations and highly abstract distributed programming styles.
Electrical damage in n-GaAs due to methane-hydrogen RIE (1990)

In order to investigate the electrical damage induced in Si-doped GaAs by CH4/H2 RIE, electrical characterisations (I-V, C-V) of Schottky diodes fabricated on the dry-etched surface were performed. After RIE carried out at 1.3 W cm-2, the Schottky barrier height decreases from 0.79 V to 0.53 V. Successive wet chemical etchings of the dry-etched surface show that the in-depth extent of this damage is at least 50 nm. Doping profiles, derived from conventional C-V analysis show a decrease in free-carrier concentration in the surface after RIE. The extent of this passivation is inversely dependent on the initial doping level. This effect is attributed to a chemical neutralisation of the doping centres by atomic hydrogen. The reactivation energy for recovery of the donor activity is around 1.75 eV.
Opioid Overdose in a Patient Using a Fentanyl Patch During Treatment with a Warming Blanket (2001)

Wireless Communication Testbed and Tools for Authentic STEM Learning (2015)

We propose a novel educational gamification approach that employs and reinforces otherwise abstract concepts currently taught in graduate-level courses to become a standard part of undergraduate communications courses in the future. In particular, we develop software tools that visually demonstrate relevant wireless communications parameters and processes, including those already taught in undergraduate communications courses (e.g., power, modulation type, data rate and bandwidth, coding rate) to students in an interactive way. We exploit our Internet-accessible wireless communication testbed X to enable students to experience wireless communication challenges and learn different solutions in realistic environments via an ordinary web browser. This paper presents our approach to authentic STEM learning and compares it with other past and ongoing initiatives. We conclude that there is a gap of practical teaching tools and methods for educating students as well as radio engineers and researchers about new trends in wireless communications with a focus on spectrum sharing.
Surface Reactive Peptides and Polymers (1991)

Acidic proteins, and phosphorylated acidic proteins in particular, appear to play several important roles in the mechanism of mineralization in biological systems. They may direct the placement of the mineral crystals within and upon the organic matrix of tissues such as bone and dentin. They may also regulate the crystal growth rate. Further they may limit the size of the formed crystals by surface adsorption. Dentin has been selected as a model for the study of these problems because it is a rich source of a unique phosphoprotein, phosphophoryn, which may serve all of these regulatory functions. As a mineralization mediator the phosphophoryn appears to bind to the collagen matrix and to act to complex inorganic ions to initiate calcium hydroxyapatite crystallization in an ordered fashion on the matrix. Studies on the native and dephosphorylated protein show the profound effect of the phosphate groups on the calcium binding properties of the phosphoprotein. The phosphophoryn molecule has distinct domains which may relate to the different regulatory activities postulated for this one molecule.

Expression and prognostic value of the lung resistance-related protein (LRP) in germ cell testicular tumors. (2004)

Immunohistochemistry is a reliable method to evaluate LRP expression in testicular germ cell tumors. A positive correlation was found between LRP immunostaining and pure teratomas. LRP expression was associated with an adverse clinical outcome and shorter overall survival. Our findings suggest that LRP has prognostic value in testicular germ cell tumors and can predict clinical outcome.
Clonal nature of the immune response to phosphorylcholine. III. Species-specific binding characteristics of rodent anti-phosphorylcholine antibodies. (1974)

The fine specificity of anti-phosphorylcholine antibodies was studied in different rodent species and 17 different inbred mouse strains. Measurements of the relative affinity and specificity of the antibodies were derived from a hemolytic plaque-inhibition assay with phosphorylcholine and two of its analogues, glycerophosphorylcholine and choline, as inhibitors. Within a given species, inhibition of plaque-forming cells was accomplished within a narrow range of ligand concentration and little individual variation was seen. Moreover, no changes in either the slopes or relative position of the inhibition curves occurred at different times after immunization. These findings suggest that a restriction in heterogeneity of the anti-phosphorylcholine antibodies exists in each of the rodent species. However, striking species-specific differences were observed in the binding characteristics of antibodies from different species of rodents.
Time and space resolved deep metagenomics to investigate selection pressures on low abundant species in complex environments (2012)

Metagenomics offers great potential for investigation of species and strain diversification over time. Recent progress in sequencing technologies have made it possible to investigate species diversification and niche adaptation in low abundant populations (<1%) in complex environments by sequencing hundreds of gigabases of DNA sequence. However, lack of replication and time series data as well as DNA extraction independent validation have limited the generalization of most earlier studies. For a period of 6 years we have studied community dynamics and operational performance in 25 Danish Enhanced Biological Phosphorus Removal (EBPR) wastewater treatment plants using qFISH and 16S sequencing and identified a surprisingly stable core community. This makes EBPR a prime target for metagenomic investigations of species diversification over time and between plants. The aim of the project was to investigate time and space resolved diversity of key species in the core EBPR community using available reference genomes and genomes assembled directly from metagenomes. <br/>A total of 500 Gb sequence was generated using Illumina HiSeq2000 for metagenomics and V4 16S rRNA gene sequencing. To track changes over time and between EBPR plants we sequenced a total of 10 samples from 3 different plants over a 3 year period at a depth of 25 Gb each. In addition, one time point was selected for deep sequencing, generating 200 Gb of sequence divided between replicates. Quantitative FISH analysis using >30 oligonucleotide probes was carried out. Data analysis was carried out largely as described in Albertsen et al., 2011 (ISME J doi:10.1038/ismej.2011.176).<br/>The DNA extraction method was optimized based on 16S rRNA and qFISH results and showed the need for optimizing the extraction method depending on the microorganisms present. Individual assemblies of the replicate data sets did not reveal major changes in gene content, although differences were present The deep metagenome made it possible to assemble several draft genomes of functional important genus' including the actinobacterial Tetrasphaera and the nitrifier Nitrospira. By mapping the raw reads to reference genomes and de novo assembled draft genomes it was possible to track changes in gene content and mutation frequency over time and between plants. The metagenome analysis of micro-diversity revealed large differences in the degree of micro-diversity within different groups of bacteria, also over time. Many of these findings could be related to niche breadth. A common core gene pool could be identified in each bacterial group, but with large differences - mainly related to phage defense. It is interesting that the observed diversity could not be resolved using FISH or V4 16S rRNA sequencing where the populations seemed much more stable. This information can be used to expand the current ecosystem models used in EBPR and contribute to the understanding of ecosystem dynamics in complex environments.<br/>
Severe Kikuchi's disease responsive to immune modulation. (2010)

Kikuchi's disease, although an uncommon entity, has been increasingly reported since it was first discovered in 1972. The most common manifestation of Kikuchi's disease, cervical lymphadenopathy, has no clinically distinguishable features. Therefore, a diagnosis of Kikuchi's disease has largely been based on clinical suspicion and histopathological confirmation. We present a 15-year-old Chinese girl with severe Kikuchi's disease, whose relapsing course was only responsive to highdose steroid and intravenous immunoglobulin therapy.
Corepressor System for Catabolite Repression of the <i>lac</i> Operon in <i>Escherichia coli</i> (1969)

Acetylated amino sugars, normally used in the biosynthesis of cell walls and cell membranes, were found to play a role as corepressors for catabolite repression of the lac operon in Escherichia coli. This conclusion was derived from studies conducted on mutants of E. coli that were able to assimilate an exogenous source of N-acetylglucosamine (AcGN) but were unable to dissimilate or grow on this compound. At concentrations less than 10(-4)m, AcGN caused severe catabolite repression of beta-galactosidase synthesis in cultures grown under either nonrepressed or partially repressed conditions. This repression occurred in the absence of any effect of AcGN on either the carbon and energy metabolism or the growth of the organism. In addition, this repression by AcGN occurred in a mutant strain that is constitutive for beta-galactosidase production, demonstrating that the AcGN effect does not involve the uptake of inducer. This model for the corepressor system of catabolite repression is discussed in relation to the existing theories on repression of the lac operon.

EDA for analog DFT? - designers must get on the bus (2009)

Design for test (DFT) for analog functions lags far behind that for digital functions, and as a result there is virtually no automation (except BIST for SerDes, PLL, and DDR). Before such automation can be developed, we must first understand the reasons for this lag and address them, since without a widely used technique, EDA companies cannot develop truly useful DFT automation. Analog design has no general-purpose DFT technique comparable to digital's scan-based design and testing. The closest possibility is the analog bus, but it is often inadequate. Let's consider three important reasons for the lack of a general analog DFT technique.
LCI (2011)

The rise of Web 2.0 with its increasingly popular social sites like Twitter, Facebook, blogs and review sites has motivated people to express their opinions publicly and more frequently than ever before. This has fueled the emerging field known as sentiment analysis whose goal is to translate the vagaries of human emotion into hard data. LCI is a social channel analysis platform that taps into what is being said to understand the sentiment with the particular ability of doing so in near real-time. LCI integrates novel algorithms for sentiment analysis and a configurable dashboard with different kinds of charts including dynamic ones that change as new data is ingested. LCI has been researched and prototyped at HP Labs in close interaction with the Business Intelligence Solutions (BIS) Division and a few customers. This paper presents an overview of the architecture and some of its key components and algorithms, focusing in particular on how LCI deals with Twitter and illustrating its capabilities with selected use cases.
Structural, vibrational and solid-state NMR studies of the halogenocuprate(I) complexes [(PPh3)2CuI2]- and [(PPh3)CuI3Cu(PPh3)]- (1989)

Single-crystal X-ray diffraction, vibrational spectroscopy, and solid state NMR spectroscopy have been used to characterize two new types of ionic copper(1) complexes. The anion in [PPh3Me]+[(PPh3)2Cu12]c-o ntains two PPh, ligands coordinated to the copper atom of a Cu12 unit in a pseudotetrahedral arrangement, with Cu-P = 2.292 (2), 2.288 (2) A, Cu-I = 2.692 (I), 2.702 ( I ) A, P-Cu-P = 121.24 (9)", and I-Cu-I = 108.62 (4)' (monoclinic, P21/c, a = 12.138 (5) A, b = 14.776 (6) A, c = 28.197 (14) A, 0 = 103.76 (4)O, Z = 4, R = 0.040 for 4490 'observed" (I > 3 4 ) ) reflections). The far-IR spectrum shows a strong band at 118 cm-l that is assigned to the antisymmetric Cu-I stretching mode of the CUI, unit. The CPMAS ,*P NMR spectrum shows a strong singlet at 18.1 ppm (relative to 85% H3Po4) due to the cation and a weaker quartet centered at -16.7 ppm due to the coordinated PPh, in the anion, with line spacings due to Cu-P coupling of 1.08, 1.20, and 1.23 kHz. The anion in [PPh,Me]+[ (PPh,)CuI,Cu(PPh,)]- consists of an approximately D,h Cu213 unit with three iodine atoms bridging the two copper atoms and with one PPh, molecule completing a pseudotetrahedral arrangement around each copper atom. The crystallographically imposed symmetry of the ion is C,,, with the 3-fold axis passing through the P-Cu bonds. The core structural parameters are (5)O, and Cu-I-Cu = 54.88 (4)' (cubic, P2,3, a = 17.744 (IO) A, Z = 4, R = 0.036 for 1390 "observed" reflections). This is the first reported example of a binuclear copper(1) complex with three bridging ligands and is an example of an unusual bonding situation in which two coordination tetrahedra are linked by sharing a common face. This has the effect of producing an unusually short Cu-- -Cu separation of 2.50 A. The far-IR spectrum shows a band at 127 cm-' that is assigned to the doubly degenerate perpendicular Cu-I stretching mode of the CutIl unit. The CPMAS NMR spectrum shows a strong singlet at 20.1 ppm due to the cation and a broad quartet centered at -15.8 ppm due to the coordinated PPh, in the anion. The splitting pattern for this quartet does not conform to expectations for an AX spin system involving coupling between I = I / , and I = ,/, nuclei. The assignments of the ~(CU-I)I R bands in both complexes are supported by approximate normal-wordinate analyses, and the resulting Cu-I force constants are compared with the values obtained in similar analyses of related iodocopper(1) complexes.
Power model validation through thermal measurements (2007)

Simulation environments are an indispensable tool in the design, prototyping, performance evaluation, and analysis of computer systems. Simulator must beable to faithfully reflect the behavior of the system being analyzed. To ensure the accuracy of the simulator, it must be verified and determined to closely match empirical data. Modern processors provide enough performance counters to validate the majority of the performance models; nevertheless, the information provided is not enough to validate power and thermal models. In order to address some of the difficulties associated with the validation of power andthermal models, this paper proposes an infrared measurement setup to capture run-time power consumption and thermal characteristics of modern chips. We use infrared cameras with high spatial resolution (10x10 μm ) and high frame rate (125fps) to capture thermal maps. To generate a detailed power breakdown (leakage and dynamic) for each processor floorplan unit, we employ genetic algorithms. The genetic algorithm finds a power equation for each floorplan block that produces the measured temperature for a given thermal package. The difference between the predicted power and the externally measured power consumption for an AMD Athlon analyzed in this paper has less than 1% discrepancy. As an example of applicability, we compare the obtained measurements with CACTI power models, and propose extensions to existing thermal models to increase accuracy.
