They also present a broadband integrated services digital network/asynchronous transfer mode (B-ISDN/ATM) management architecture that will support this CNM service and its evolution.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Engineering of human-type O-glycosylation in<i><i>Nicotiana benthamiana</i></i>plants (2012)

Therapeutic properties of recombinant proteins are very often affected by the composition and heterogeneity of their glycans. Conventional expression systems for recombinant pharmaceutical proteins typically do not address this problem and produce a mixture of glycoforms that are neither identical to human glycans nor optimized for enhanced efficacy. In terms of glycosylation, plants offer certain advantages over mammalian cells as the N-glycosylation pathway of plants is comparably simple and a typical mammalian O-glycosylation pathway is not present at all. During the last ten years we have developed a plant-based expression platform for the generation of recombinant glycoproteins with defined N-glycans. Now we have extended our tool-box for glyco-engineering in the tobacco related species Nicotiana benthamiana toward the production of tailored mucin-type O-glycans on recombinant proteins.
Short distance eight-channel parallel optical link for data communications (2003)

The design, setup, and characterization of an eight-channel parallel optical interconnection for data communications with low power consumption and high channel density are presented. The link is electrically compatible with ECL (emitter coupled logic) integrated circuits. It consists of arrays of laser diodes, planar waveguides, photodiodes, and amplifiers. The total data throughput is 5 Gb/s (625 Mb/s per channel); the width is 1 mm (125- mu m pitch); and the total power consumption is less than 1 W. The signal delay (latency) from the electrical input at the emitter to the electrical output of the receiver is given by the propagation time through the optical waveguide plus a value of less than 1.5 ns, which is due to the delay in the optoelectronic and electric components (mostly the receiver amplifier). Special components were designed and fabricated: laser diodes, photodiodes, amplifiers, and planar optical waveguides, each as an array with eight channels.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A simplified maximal power controller for terrestrial photovoltaic panel arrays (1982)

Perusal of the V-I characteristics of commercial solar panels with insolation, ambient temperature and production spreads as parameter, indicate that the maximum power is obtained from such a panel when it is loaded to a working voltage that is a fixed percentage of its open circuit voltage within (+2)%. This contribution describes a system that uses this characteristic to achieve maximum power control by determining the open circuit voltage and automatically loading the panel to the maximum power point as applied to a battery charging installation. The description includes the application of a novel modified darlington circuit to boost the efficiency of a pulse width controlled switch mode type regulator by reducing the darlington saturation voltage by a compensating voltage. Advanced switching technology is applied to reduce switching losses, and maximise efficiency.

Mechanism of device degradation in n- and p-channel polysilicon TFTs by electrical stressing (1990)

The effects of electrical stress on hydrogenated n- and p-channel polysilicon thin-film transistors are discussed. The on-state caused the most significant degradation, whereas off-state and accumulation conditions resulted in negligible degradation. The on-state stress degraded the threshold voltage, trap state density, and subthreshold sharpness of both n- and p-channel devices toward perhydrogenated values, and the rates of degradation increased with stressing biases. The field-effect mobility and leakage current, however, were not degraded by stressing. The mechanism of device degradation may be attributed to the metastable creation of midgap states within the polysilicon channel, as opposed to gate dielectric charge trapping or interface state generation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Your browsing behavior for a Big Mac: Economics of Personal Information Online (2011)

Most online services (Google, Facebook etc.) operate by providing a service to users for free, and in return they collect and monetize personal information (PI) of the users. This operational model is inherently economic, as the "good" being traded and monetized is PI. This model is coming under increased scrutiny as online services are moving to capture more PI of users, raising serious privacy concerns. However, little is known on how users valuate different types of PI while being online, as well as the perceptions of users with regards to exploitation of their PI by online service providers. In this paper, we study how users valuate different types of PI while being online, while capturing the context by relying on Experience Sampling. We were able to extract the monetary value that 168 participants put on different pieces of PI. We find that users value their PI related to their offline identities more (3 times) than their browsing behavior. Users also value information pertaining to financial transactions and social network interactions more than activities like search and shopping. We also found that while users are overwhelmingly in favor of exchanging their PI in return for improved online services, they are uncomfortable if these same providers monetize their PI.
A new minimum-time control law for a one-mode model of a flexible slewing structure (1993)

The construction of a minimum-time control law for a single-axis, undamped, one-mode model of a flexible slewing structure is described. The set of necessary and sufficient conditions for optimality is developed using phase-plane techniques, and is given in terms of the vibration frequencies and the rigid-body states. This effectively provides the switching hypersurface in four-dimensional space. The resulting control strategy can be implemented on line since no a priori computation of switching times is required.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Improved method for the synthesis of o-glycosylated fmoc amino acids to be used in solid-phase glycopeptide synthesis (Fmoc = fluoren-9-ylmethoxycarbonyl) (1990)

The building blocks O1-(2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl)-Nα-(fluoren-9-ylmethoxycarbonyl)serine (5) and O1-(2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl)-Nα-(fluoren-9-ylmethoxycarbonyl)threonine (6) for use in solid-phase glycopeptide synthesis can be obtained via their ally esters by mild treatment with tetrakis(triphenylphosphine)palladium(0) and tributyltin hydride with no Fmoc elimination or sugar cleavage or anomerization.
Mineralocorticoid Receptor Gene Variants as Determinants of HPA Axis Regulation and Behavior (2010)

We tested if common mineralocorticoid receptor (MR) gene variants contribute to the variability in neuroendocrine control and behavioral reactivity as observed in humans. For that purpose we screened for genetic variability and tested functionality of the identified human MR gene variants in vitro. Four haplotypes were tested for transactivational capacity in vitro and showed profound significant differences when stimulated with cortisol. The MR gene variants were associated with basal levels of cortisol, cortisol levels after dexamethasone administration and with stress-induced hypothalamic-pituitary-adrenal axis and autonomic reactivity. In an elderly cohort, one of the functional MR gene variants, MR-I180V, associated with higher feelings of depression. Moreover, we found an association with neuroticism in a second cohort consisting of depressed patients. In conclusion, we report here new findings on common functional human MR gene variants which reveal a hitherto unknown role of these variants in neuroticism conferring vulnerability to stress-related mental disorders, such as depression and posttraumatic stress syndrome.
OFDM Transmission for Time-Based Range Estimation (2010)

OFDM is proposed for time-based range estimation (TBRE) and analyzed with respect to its accuracy, both theoretically, in terms of its Cramer-Rao lower bound (CRLB), and practically, in terms of its maximum likelihood estimator (MLE). The CRLB for OFDM transmission is compared to that for pseudo-noise (PN) transmission, demonstrating a large performance gap in favour of OFDM. Moveover, the MLE for TBRE is compared to the commonly used MLE for channel estimation (CE), demonstrating a performance gap in favour of the MLE for TBRE. Finally, the CRLB for OFDM is compared to its corresponding MLE for TBRE, demonstrating a good agreement in performance except for the so-called ¿threshold effect¿, which is analyzed analytically in this letter.
Deformation of Poly crystalline Transition Metal Carbides (1967)

Plastic deformation was studied in hot‐pressed poly crystalline specimens of titanium carbide, vanadium carbide, niobium carbide, tantalum carbide, and tungsten carbide tested in four‐point bending and under compression to 2100°C. Transition from brittle to ductile behavior occurred at approximately half the absolute melting temperature for each material. Above this temperature the yield strengths decreased exponentially with increasing temperature. Between the ductile‐brittle transition temperature and about 1900°C the apparent activation energy for flow in the carbides with the rock‐salt structure was near O.S ev/atom. Above 1900°C the value was approximately 2 ev/atom; the value for tungsten carbide was apparently 0.3 ev/atom to 2070°C. Vanadium carbide and titanium carbide recovered extensively on annealing for short times near 2000°C. No such recovery occurred in tungsten carbide under these conditions. The results for polycrystalline carbides were compared with available data for single crystals of titanium carbide.
Is working for a big nursery chain better? (2001)

Do nice things come in small packages, or is big beautiful? Maybe both statements are true… But how does this apply to day nurseries?
Some Computed Optical Properties of Antireflection Coatings (1962)

Optical properties of two-layer antireflection systems are discussed. Theory is applied to study the optical performance of bismuth-oxide/magnesium-fluoride bilayers. The theoretical study includes graphs and numerical tables showing the spectral reflectances for different glass substrates, the effect of film-thickness mismatching and the spectral reflectance for plane-polarized incident light.
Shape-Controlled Synthesis of Magnetic Iron Oxide@SiO<sub>2</sub>–Au@C Particles with Core–Shell Nanostructures (2015)

The preparation of nonspherical magnetic core-shell nanostructures with uniform sizes still remains a challenge. In this study, magnetic iron oxide@SiO2-Au@C particles with different shapes, such as pseduocube, ellipsoid, and peanut, were synthesized using hematite as templates and precursors of magnetic iron oxide. The as-obtained magnetic particles demonstrated uniform sizes, shapes, and well-designed core-shell nanostructures. Transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX) analysis showed that the Au nanoparticles (AuNPs) of ∼6 nm were uniformly distributed between the silica and carbon layers. The embedding of the metal nanocrystals into the two different layers prevented the aggregation and reduced the loss of the metal nanocrystals during recycling. Catalytic performance of the peanut-like particles kept almost unchanged without a noticeable decrease in the reduction of 4-nitrophenol (4-NP) in 8 min even after 7 cycles, indicating excellent reusability of the particles. Moreover, the catalyst could be readily recycled magnetically after each reduction by an external magnetic field.
Insulin binding to rat intestinal epithelial cells following partial small-bowel resection (1986)

Partial (60%) resection of rat small bowel was performed in order to obtain a model of intestinal mucosal hyperplasia for studying specific insulin binding. The affinity, but not the binding capacity, of insulin receptors in the adaptive mucosa decreased three and seven days following enterectomy. This modification took place only in crypt cells but not in mature villous cells. Since plasma insulin levels were not altered by the surgical manipulation, the observed decrease of insulin binding could not be related to regulation by insulin concentration. These results do not support a trophic role of insulin on intestinal mucosa and appear to be more a consequence of the hyperactive status of proliferation and differentiation at the mucosal level.
Acute Pulmonary Vein Isolation Is Achieved by a Combination of Reversible and Irreversible Atrial Injury After Catheter Ablation (2012)

The higher T2 signal on acute scans and greater decline in DE on chronic imaging in patients with recurrences suggest that they have more reversible tissue injury, providing a potential mechanism for pulmonary vein reconnection, resulting in arrhythmia recurrence.
Non-viral, integrin-mediated gene transfer into fibroblasts from patients with lysosomal storage diseases (2001)

The integrin-mediated transfer of genes encoding lysosomal enzymes into cells results in the secretion of large amounts of normal enzyme that could be taken up by other cells. This could be a useful strategy for enzyme-replacement therapy.
Latent variable decomposition of spectrograms for single channel speaker separation (2006)

In this paper we present an algorithm for the separation of multiple speakers from mixed single-channel recordings by latent variable decomposition of the speech spectrogram. We model each magnitude spectral vector in the short-time Fourier transform of a speech signal as the outcome of a discrete random process that generates frequency bin indices. The distribution of the process is modelled a mixture of multinomial distributions, such that the mixture weights of the component multinomials vary from analysis window to analysis window. The component multinomials are assumed to be speaker specific and are learnt from training signals for each speaker. The distributions representing magnitude spectral vectors for the mixed signal are decomposed into mixtures of the multinomials for all component speakers. The frequency distribution, i.e. the spectrum for each speaker is reconstructed from this decomposition. Experimental results show that the proposed method is very effective at separating mixed signals.
A SimPLR method for routability-driven placement (2011)

Highly-optimized placements may lead to irreparable routing congestion due to inadequate models of modern interconnect stacks and the impact of partial routing obstacles. Additional challenges in routability-driven placement include scalability to large netlists and limiting the complexity of software integration. Addressing these challenges, we develop lookahead routing to give the placer advance, firsthand knowledge of trouble spots, not distorted by crude congestion models. We also extend global placement to (i) spread cells apart in congested areas, and (ii) move cells together in less-congested areas to ensure short, routable interconnects and moderate runtime. While previous work adds isolated steps to global placement, our SIMultaneous PLace-and-Route tool SimPLR integrates a layer- and via-aware global router into a leading-edge, force-directed placer. The complexity of integration is mitigated by careful design of simple yet effective optimizations. On the ISPD 2011 Contest Benchmark Suite, with the official evaluation protocol, SimPLR outperforms every contestant on every benchmark.
Continuous Glucose Monitoring: The Future of Diabetes Management (2008)

In Brief Continuous glucose monitoring (CGM) technology has the potential to revolutionize diabetes care in the near future because of the real-time feedback it provides about therapeutic interventions and variations in lifestyle or dietary intake. In short, CGM has made the attainment of near-normal blood glucose concentrations an achievable goal for most patients with diabetes. Several challenges remain to be addressed, however, including the high cost of the devices, limitations in approved clinical uses, and insurance coverage for the technology. This article reviews the CGM technology currently available in the United States, its approved uses, and its limitations.
Christian missionaries & the state in the Third World (2002)

The education of many Third World leaders by Christian missionaries is a decisive factor in world politics today. Christian missionaries from a diversity of backgrounds - Africans as well as Americans and Europeans - contributed to the construction, destruction and reconstruction of state structures in Africa and the Caribbean, through educational activity, and attempts at healing and trade, as well as by preaching, prayer and other sacramental endeavours. This is a study of Christian missionaries and the state in the Third World.
Tailoring the software process to project goals and environments (1987)

This paper presents a methodology for improving the software process by tailoring it to the specific project goals and environment. This improvement process is aimed at the global software process model as well as methods and tools supporting that model. The basic idea is to use defect profiles to help characterize the environment and evaluate the project goals and the effectiveness of methods and tools in a quantitative way. The improvement process is implemented iteratively by setting project improvement goals, characterizing those goals and the environment, in part, via defect profiles in a quantitative way, choosing methods and tools fitting those characteristics, evaluating the actual behavior of the chosen set of methods and tools, and refining the project goals based on the evaluation results. All these activities require analysis of large amounts of data and, therefore, support by an automated tool. Such a tool — TAME (Tailoring A Measurement Environment) — is currently being developed.
Synthesis of nanoparticles: sunlight formation of gold nanodecahedra for ultra-sensitive lead-ion detection (2011)

Aqueous solution containing two additives, chloroauric acid (HAuCl4) and trisodium citrate (Na3C6H5O7), was irradiated by sunlight, without any additional stimulus such as electric power, to form high-yield Au decahedra. Those Au nanodecahedra were thermodynamically stable and exhibited high performance sensing of lead (Pb2+) ions.
Machine Learning Approach for Language Identification & Transliteration (2015)

In this paper, we describe the system that we developed as part of our participation to the FIRE-2014 Shared Task on Transliterated Search. We participated only for Subtask 1 that focused on labeling the query words. The entire process consists of the following components: language identification of each word in text, named entity recognition and classification (NERC) and transliteration of Indian language words written in non-native scripts to the corresponding native Indic scripts. The proposed methods of language identification and NERC are based on supervised approaches, where we use several machine learning algorithms. Our transliteration framework is based on modified joint source channel model. Experiments on benchmark setup show that we achieve quite encouraging performance for both the pairs of languages, viz. Bangla-English and Hindi-English. It is also to be noted that we did not make use of heavy domain-specific resources and/or tools, and therefore this can be easily adapted to the other domains and/or languages.
