Designing for ROI: toward a value-driven discipline for e-commerce systems design (2003)

E-business management is an on-going process of understanding consumer needs and developing online solutions to meet those needs. To be effective in today's competitive environment of e-commerce, e-businesses cannot afford to neglect justifying the return on investment (ROI) of their online operations. Ideally, companies would like to understand how users are using their Web site and how this translates into value creation (or value leakage) so that online solutions can be implemented to increase business performance. However, the current situation is that such value-driven management is not possible due to the lack of tools and methods that can provide a clear link between systems design and business performance. This paper presents a value-driven systems design methodology for e-commerce Web sites. The focus of our methodology is on identifying value-creating opportunities and value-diminishing problems through the analysis of actual customer Web site usage behaviors through Web usage mining. The identification of value-creating opportunities and value-diminishing problems enables us to plan for designing additional Web site features and for redesigning existing functionalities to increase business performance and maximize design ROI.
Two-Tier Multiple Query Optimization for Sensor Networks (2007)

When there are multiple queries posed to the resource-constrained wireless sensor network, it is critical to process them efficiently. In this paper, we propose a two-tier multiple query optimization (TTMQO) scheme. The first tier, called base station optimization, adopts a cost-based approach to rewrite a set of queries into an optimized set that shares the commonality and eliminates the redundancy among the queries in the original set. The optimized queries are then injected into the wireless sensor network. In the second tier, called in-network optimization, our scheme efficiently delivers query results by taking advantage of the broadcast nature of the radio channel and sharing the sensor readings among similar queries over time and space at a finer granularity. Our experimental results indicate that our proposed TTMQO scheme offers significant improvements over the traditional single query optimization technique.
An Anastomotic Device for Microvascular Surgery: Evolution (1984)

A new anastomotic device is demonstrated that is suitable in microvascular surgery for repairing severed blood vessels and inserting vein grafts. Initial pilot studies indicate a 100% patency rate for vessel anastomosis, and a one-year study produced a 96% success rate. However, histological examination revealed notable vessel deterioration with a rigid device. Therefore, an absorbable anastomotic coupler was developed that demonstrates a high patency rate (92%) in both arteries and veins, with substantial absorption of the device by 70 days. Healing at the anastomotic site was qualitatively similar to that obtained with a sutured anastomosis; there was endothelialization by 14 days and absorption of the device by 70 days.
Specific inhibitors for prolyl endopeptidase and their anti-amnesic effect. (1987)

Several peptides and peptide derivatives were tested for their inhibitory effect on prolyl endopeptidase and possible properties as anti-amnesic agents. Among the compounds tested, Z-Gly-Pro-CH2Cl, Z-Val-prolinal, Boc-Pro-prolinal, Z-Pro-prolinal, aniracetam and pramiracetam inhibited the enzyme activities at Ki values in the order of nM to microM, and the effect of the prolinal-containing peptide derivatives was specific for prolyl endopeptidase. Z-Pro-prolinal was the most effective inhibitor in vitro (Ki = 5 nM) and in vivo (50 to 70% inhibition in various organs of rat at a dose of 1 mumol/animal i.p.). Regional differences were observed in the effect of inhibitors on the brain enzyme activities: most active in mesencephalon, followed by striatum, cerebellum, hippocampus, hypothalamus; and inactive in cerebral cortex and medulla oblongata. In the passive avoidance learning test using rats, pretreatment with Z-Pro-prolinal prevented the induction of amnesia by scopolamine at the dose of 1 mumol/animal, i.p. Z-Val-prolinal, Z-Pyr-prolinal and Z-Gly-Pro-CH2Cl were also effective in the retention test at 24 and 48 h after the training trial. The antiamnesic effect of these compounds was approximately parallel to the in vitro inhibitory activities on prolyl endopeptidase. These results suggest the possibility that the inhibitors exhibit their anti-amnesic effect through the regulation of the enzyme activity in the brain.
Optical properties of germanium monolayers on silicon (2001)

Photoluminescence and Raman spectra of thin germanium layers grown on silicon at a low temperature (250°C) have been studied. In structures of this kind, in contrast to those grown at high temperatures, luminescence from quantum wells is observed at germanium layer thicknesses exceeding ∼9 monolayers (ML). With the development of misfit dislocations, the luminescence lines of quantum wells are shifted to higher energies and transverse optical (TO) phonons involved in the luminescence are confined to a quasi-2D germanium layer. Introduction of an additional relaxed Si0.95Ge0.05 layer into the multilayer Ge/Si structure leads to a substantial rise in the intensity and narrowing of the luminescence line associated with quantum dots (to 24 meV), which points to their significant ordering.
Protocols and services for distributed data-intensive science (2001)

We describe work being performed in the Globus project to develop enabling protocols and services for distributed data-intensive science. These services include: * High-performance, secure data transfer protocols based on FTP, plus a range of libraries and tools that use these protocols * Replica catalog services supporting the creation and location of file replicas in distributed systems These components leverage the substantial body of “Grid” services and protocols developed within the Globus project and by its collaborators, and are being used in a number of data-intensive application projects.
Enhanced Fractional Frequency Reuse for large-scale OFDMA networks with heterogeneous cell layout: Optimization and performance evaluation (2010)

Fractional Frequency Reuse (FFR) is one of the key concepts for mitigating inter-cell interference and improving cell-edge performance in OFDMA networks. The standard FFR scheme is intuitive and optimal for the hexagon-shaped cell pattern. In contrast, real-life OFDMA systems have very irregular cell layout, thus the number of surrounding cells and their respective interference vary significantly over the network. For such scenarios, the standard scheme, if applicable at all, is inadequate because the number of sub-bands and the reuse factor are fixed. To overcome the limitations, we present enhanced FFR (EFFR) that allows for high flexibility in the total number of sub-bands as well as the allocation of sub-bands in edge zones. An optimization algorithm is developed to determine sub-band allocation to maximize the cell-edge throughput. Hence EFFR adapts the allocation and reuse pattern to the irregularity of each individual network. Evaluations based on networks with realistic radio propagation conditions show the high performance of EFFR in improving cell-edge throughput. The improvement allows for better trade-off between cell-center and cell-edge throughput. These results along with the analysis demonstrate the benefits of EFFR to performance engineering of OFDMA networks.

Isolation from Human Erythrocytes of a New Membrane Protein Which Inhibits the Formation of Complement Transmembrane Channels1 (1988)

A protein which inhibited complement channel formation was isolated from extracts of papain-digested human erythrocyte membranes using DEAE-Sephacel, Bio-Gel A0.5m column chromatographies, and preparative sodium dodecyl sulfate-polyacrylamide gel electrophoresis followed by transfer to nitrocellulose paper and elution with 2% NP-40 solution. The purified protein showed a molecular weight of 18 kDa, and efficiently inhibited hemolysis of EC5-7 cells with C8 and C9, but did not show any decay-accelerating activity to C5 convertase. Immunochemical analysis of native membranes after sodium dodecyl sulfate-polyacrylamide gel electrophoresis using the antibody against this protein gave a single band having the same mobility as this protein; papain did not eliminate a significant portion of this protein.
Building native protein conformation from NMR backbone chemical shifts using Monte Carlo fragment assembly (2007)

We have been analyzing the extent to which protein secondary structure determines protein tertiary structure in simple protein folds. An earlier paper demonstrated that three-dimensional structure can be obtained successfully using only highly approximate backbone torsion angles for every residue. Here, the initial information is further diluted by introducing a realistic degree of experimental uncertainty into this process. In particular, we tackle the practical problem of determining three-dimensional structure solely from backbone chemical shifts, which can be measured directly by NMR and are known to be correlated with a protein's backbone torsion angles. Extending our previous algorithm to incorporate these experimentally determined data, clusters of structures compatible with the experimentally determined chemical shifts were generated by fragment assembly Monte Carlo. The cluster that corresponds to the native conformation was then identified based on four energy terms: steric clash, solvent-squeezing, hydrogen-bonding, and hydrophobic contact. Currently, the method has been applied successfully to five small proteins with simple topology. Although still under development, this approach offers promise for high-throughput NMR structure determination.
Using wiktionary for computing semantic relatedness (2008)

We introduce Wiktionary as an emerging lexical semantic re-source that can be used as a substitute for expert-made re-sources in AI applications. We evaluate Wiktionary on the pervasive task of computing semantic relatedness for English and German by means of correlation with human rankings and solving word choice problems. For the first time, we ap-ply a concept vector based measure to a set of different con-cept representations like Wiktionary pseudo glosses, the first paragraph of Wikipedia articles, English WordNet glosses, and GermaNet pseudo glosses. We show that: (i) Wiktionary is the best lexical semantic resource in the ranking task and performs comparably to other resources in the word choice task, and (ii) the concept vector based approach yields the best results on all datasets in both evaluations.
Visible–NIR tunable Pr^3+-doped fiber laser pumped by a GaN laser diode (2009)

We demonstrated continuous wave laser operation with a tunable range of over 300 nm in the visible and near-infrared regions (479-497, 515-548, 597-737, 849-960 nm) using a single 9-cm Pr(3+)-doped ZBLAN fiber pumped by a GaN laser. The total tunable range was 6469 cm(-1), which is wider than that of conventional Ti:sapphire lasers.

Roll-milling time dependence of the HTV silicone rubber indicates that the alpha is closely affected by the dispersion of nanopowders in the rubber matrix.

A solid state actuator based on polypyrrole (PPy) and a solid electrolyte NBR working in air (2005)

The solid polymer electrolyte based conducting polymer actuator was presented. In the preparation of acutuator module, an ionic liquid impregnated a synthetic rubber (NBR) and PPy were used as a solid polymer electrolyte and conducting polymer, respectively. An ionic liquid, 1-butyl-3-methylimidazolium bis (trifluoromethyl sulfonyl)imide (BMITFSI) is gradually dispersed into the NBR film and the conducting polymer, PPy was synthesized on the surface of NBR. The ionic conductivity of new type solid polymer electrolyte as a function of the immersion time was investigated. The cyclic voltammetry responsed and the redox switching dynamics of PEDOT in NBR matrix were studied. The displacement of the actuator was measured by laser beam.
On the speedup required for work-conserving crossbar switches (1999)

This paper describes the architecture for a work-conserving server using a combined I/O-buffered crossbar switch. The switch employs a novel algorithm based on output occupancy, the lowest occupancy output first algorithm (LOOFA), and a speedup of only two. A work-conserving switch provides the same throughput performance as an output-buffered switch. The work-conserving property of the switch is independent of the switch size and input traffic pattern. We also present a suite of algorithms that can be used in combination with LOOFA. These algorithms determine the fairness and delay properties of the switch. We also describe a mechanism to provide delay bounds for real-time traffic using LOOFA. These delay bounds are achievable without requiring output-buffered switch emulation.
Radiolocalization of human pancreatic tumors in athymic mice by monoclonal antibody DU-PAN 1. (1990)

Monoclonal antibodies that selectively bind to pancreatic tumors may be useful in the therapy and diagnosis of pancreatic carcinoma. In this study we have examined the tumor localization of radioiodinated DU-PAN 1, a mouse monoclonal antibody that is selective for a human pancreatic cancer-associated antigen. After radiolabeling, both DU-PAN 1 intact monoclonal antibody and F(ab')2 fragments retained immunoreactivity and showed high affinity for the pancreatic tumor cell line CA13 in vitro. Paired-label biodistribution studies in nude mice bearing CA13 s.c. xenografts were performed. Mice received both 131I-labeled DU-PAN 1 immunoglobulin G2a or F(ab')2 fragment and 125I-labeled mouse myeloma immunoglobulin G2a or F(ab')2 fragment. Tumor uptake for 5-micrograms doses of DU-PAN 1 immunoglobulin ranged from 4.8 to 11.83% injected dose/g. Tumor uptake values for mice given 5-micrograms doses of DU-PAN 1 F(ab')2 ranged from 3.9 to 6.9% injected dose/g. Tumor uptakes of the respective myeloma controls were lower in all cases when compared with the DU-PAN 1 preparations. Tumor localization indices for 5-micrograms doses of DU-PAN 1 immunoglobulin were 3.0 and 24 h and 2.9 at 48 h. For 5-micrograms doses of DU-PAN 1 F(ab')2, tumor localization indices were 29.9 at 24 h and 90.0 at 48 h. In most cases, tumor:normal tissue ratios were greater than 3 at all time points, indicative of tumor selectivity for both DU-PAN 1 preparations, but the ratios were considerably higher using the DU-PAN 1 F(ab')2. The F(ab')2 fragment thus displays better tumor localization characteristics when compared with the intact immunoglobulin. Protein doses of DU-PAN 1 F(ab')2 of between 5 and 10 micrograms gave the best localization, although protein doses of up to 100 micrograms could be administered before apparent tumor saturation was seen.

CD28- T lymphocytes. Antigenic and functional properties (1993)

A subset of CD8+ alpha beta-TCR/CD3+ T lymphocytes in adult human peripheral blood lacks expression of CD28, a membrane receptor for the B7/BB1 B cell differentiation Ag that is involved in T cell activation. CD28-8+ T cells were not observed in the thymus and were present at only low frequency in cord blood, suggesting that these cells may represent a type of "memory" population. Consistent with this interpretation, CD28-8+ T cells were morphologically large, granular lymphocytes and expressed CD54 (intercellular adhesion molecule-1), CD58 (lymphocyte function-associated Ag-3 (LFA)), and high levels of CD11a (LFA-1), but did not express Ag associated with acute activation (e.g., HLA-DR, CD25, CD69). Freshly isolated CD28-8+ T lymphocytes mediated potent anti-CD3 redirected cytotoxicity against FcR-bearing targets, demonstrating that the CD3/TCR complex is functional and that these cells possess cytolytic activity. However, the anti-CD3-induced proliferative response of CD28-8+ T cells was substantially less than CD28+8+ T cells and this deficiency could not be overcome by addition of exogenous IL-2. A large panel of T cell clones were produced from the CD28+8+ and CD28-8+ T cell populations by single cell sorting using a flow cytometer. CD28 expression was stable on clones derived from CD28+8+ T lymphocytes, whereas CD28 expression was quite variable and apparently reexpressed on some clones generated from the CD28-8+ T cell population. As with the freshly isolated cells, CD28-8+ T cell clones were cytotoxic, but anergic to anti-CD3- induced proliferation and could not be costimulated using B7 or CD58 (LFA-3) murine L cell transfectants. These results indicate that CD28- and CD28+ T cells may play different roles in an immune response.
Oxygenation and Vasodilatation in Relation to Diabetic and Other Proliferative Retinopathies (1983)

The features of proliferative retinopathies are reviewed with reference to the vasodilatation that is a common stage in their pathogenesis. Vasodilatation in the retina is discussed in terms of a model in which vessel wall stretch in the retinal venules leads to leakage and proliferation. The beneficial effects of treatments such as panretinal photocoagulation and vitrectomy on the retinal hemodynamics are shown to agree with the hypothetical model.
A ring-like nucleoid is not necessary for radioresistance in the Deinococcaceae (2005)

There is no obvious relationship between the shape of a species' nucleoid and extreme radioresistance. However, the genomes of all extremely radioresistance species examined are highly condensed relative to more radiosensitive species. Whether DNA in this tightly packed configuration contributes to the radioresistance of these bacteria remains unknown, but this common structural feature appears to limit diffusion of fragments generated post-irradiation even in cells incapable of repairing strand breaks.
Phenolics Composition and Antioxidant Activity of Sweet Basil (<i>Ocimum basilicum</i> L.) (2003)

The antioxidant activity of a methanolic extract of Ocimum basilicum L. (sweet basil) was examined using different in vitro assay model systems. The crude extract was fractionated on a Sephadex LH-20 column, and six fractions were identified. The DPPH scavenging assay system and the oxidation of the soy phosphotidylcholin liposome model system were used to evaluate the antioxidant activity of each fraction. Fraction IV showed the strongest activity followed by fractions V and VI. Phenolic compounds responsible for the antioxidative activity of the fractions were characterized by atmospheric pressure chemical ionization liquid chromatography-mass spectrometry. The major antioxidant compound in fraction IV was confirmed as rosmarinic acid by (1)H NMR and characteristic fragmentations in the mass spectrum. Moreover, the native of antioxidant activity of rosmarinic acid in the liposome system was examined. The results showed that one rosmarinic acid can capture 1.52 radicals, and furthermore, the existence of a synergistic effect between alpha-tocopherol and rosmarinic acid was revealed.
