Approaching and leave-taking (2007)

A major difference between face-to-face interaction and computer-mediated communication is how contact negotiation---the way in which people start and end conversations---is managed. Contact negotiation is especially problematic for distributed group members who are separated by distance and thus do not share many of the cues needed to help mediate interaction. An understanding of what resources and cues people use to negotiate making contact when face-to-face identifies ways to design support for contact negotiation in new technology to support remote collaboration. This perspective is used to analyze the design and use experiences with three communication prototypes: Desktop Conferencing Prototype, Montage, and Awarenex. These prototypes use text, video, and graphic indicators to share the cues needed to gracefully start and end conversations. Experiences with using these prototypes focused on how these designs support the interactional commitment of the participants---when they have to commit their attention to an interaction and how flexibly that can be negotiated. Reviewing what we learned from these research experiences identifies directions for future research in supporting contact negotiation in computer-mediated communication.
Induction of ID2 Expression by Hypoxia-inducible Factor-1 (2004)

ID (inhibitor of differentiation/DNA binding) proteins, frequently deregulated in advanced human malignancies, can participate in multiple fundamental traits of cancer, such as block of differentiation, increased proliferation, tissue invasiveness, and angiogenesis. We have previously demonstrated that hypoxia decreases expression of neuronal marker genes in neuroblastoma, but induces genes expressed in the neural crest, such as ID2. Because of its involvement in normal neural crest development and its ability to inhibit proneuronal bHLH proteins, the hypoxic induction of ID2 was of particular interest. Here we report fast induction kinetics of ID2 expression in hypoxic neuroblastoma cells. The up-regulation of ID2 was abolished by addition of actinomycin D, implicating a hypoxia-driven transcriptional mechanism. Analyzing the ID2 promoter revealed several potential binding sites for hypoxia-inducible factors. Subsequent electrophoretic mobility shift and chromatin immunoprecipitation assays demonstrated two functional HIF-1 binding sites within ID2 gene regulatory sequences located at -725 and -1893 relative to the transcriptional initiation point. In transfection assays, DNA constructs of the ID2 promoter, including the functional HIF-1 binding sites, induced luciferase reporter activity in a HIF-1-specific manner. These observations demonstrate that ID2 is actively engaged by hypoxia and represents a novel HIF-1 target. Hypoxia-induced ID2 expression could play a significant role in the previously observed dedifferentiation of hypoxic neuroblastoma cells, which in a clinical setting could lead to less mature and more aggressive tumors.
Solving Constrained Nonlinear Optimization Problems with Particle Swarm Optimization (2002)

This paper presents a Particle Swarm Optimization (PSO) algorithm for constrained nonlinear optimization problems . In PSO, the potential solutions, called particles, are &quot;flown&quot; through the problem space by learning from the current optimal particle and its own memory. In this paper, preserving feasibility strategy is employed to deal with constraints. PSO is started with a group of feasible solutions and a feasibility function is used to check if the new explored solutions satisfy all the constraints. All particles keep only those feasible solutions in their memory. Eleven test cases were tested and showed that PSO is an efficient and general solution to solve most nonlinear optimization problems with nonlinear inequality constraints.
Neuroprotection and thrombolysis: combination therapy in acute ischaemic stroke (2006)

The administration of oral aspirin within 48 h and tissue plasminogen activator within 3 h of ischaemic stroke onset remain the only treatments that have been shown to have clinical benefit. There has been much excitement about neuroprotection over the last two decades, as it may minimise the harmful effects of ischaemic neuronal damage. Although each step along the ischaemic cascade offers a potential target for therapeutic intervention, and neuroprotection has shown benefit in animal studies, this has been difficult to translate to humans. Some hope has been offered by the recent finding that the free radical scavenger NXY-059 may improve outcomes in patients presenting within 6 h of onset of ischaemic stroke. There is logic to the idea that neuroprotection may be most effective when reperfusion has occurred with thrombolysis, as the neuroprotectant will have greater access to ischaemic tissue and the opportunity is presented to minimise free radical-mediated reperfusion injury. Numerous studies in animal models support this view, but the concept has not, as yet, been rigorously tested in humans.
RailWear Estimation for Predictive Maintenance: a strategic approach (2018)

Since the very beginning of rail transport, wear has been identified as one of the dominant damage mechanisms that influence the Remaining Useful Life (RUL) of rail tracks. Whereas maintenance of the track is now predominantly executed at fixed intervals or based on yearly inspections, the accurate prediction of rail wear could considerably improve the maintenance process. The present work proposes a method for long-term rail wear prediction using measurements of actual rail and wheel profiles as starting point. By doing so, the computational expensive step of updating the rail profile in a wear calculation, as is done in presently used methods, can be omitted. The proposed method is used to study a number of generic trends, varying curve radius and rail or wheel profile. Further, the method is validated against measured wear on actual track sections for moderate curves. Finally, it can easily be extended to include variations in operational usage of the track (type / weight of trains, geometric details, slip conditions) in the future. The method presented in this paper can therefore assist in improving the track maintenance process by maximizing the utilization of the track service life, and minimizing maintenance costs.
Analysis and implications of residual metal on spacer material in the self-align silicide process for VSLI manufacturing (2002)

We have investigated the effect of rapid thermal annealing (RTA), titanium capping, substrate Ar plasma pre-cleaning and post second RTA stripping on the amount of metal residual on silicon nitride and silicon oxide films during the cobalt (Co) self-aligned silicidation process. If our standard silicide process was used, low levels (Detection limit E10 cm/sup -2/) of Co were retained regardless of substrate and process conditions. Increasing RTA temperature of Co films that have not been capped with titanium (Ti) had relatively high uniform concentration levels throughout the annealing range. If the Co films are Ti capped the Co decreased in concentration with an increasing annealing temperature. The Ti retention however started several orders of magnitude higher than that of Co and increased slightly with increasing temperature. Pre-cleaning with Ar/sup +/ plasma and with aggressive strip led to lower retention of Co and Ti. Undoped silicon oxide was very temperature sensitive and retains more Co than Si/sub 3/N/sub 4/ or thermal SiO/sub 2/ films. Thermal oxide films behave similar to silicon nitride. Chemical bonding data suggest that cobalt combines with silicon, near the surface (>20A). Titanium capping, annealing temperature, free silicon in substrates, chemical strip and film surface conditions are the determining factors for the level of retention. Residual Co and Ti can be nearly eliminated if an additional post RTA wet strip (aggressive) is used, but it must be metered with knowledge that it will be done at the expense of Co silicide removal from poly gate and active regions.
A Two-layer Geo-cloud based Dynamic Replica Creation Strategy (2013)

To improve data availability and reduce user access latency, geo-cloud based data replication is widely used in large global Web sites, such as Facebook. However, as the popularity of data is different and will change as time goes by, simple static replica creation strategies that assign the same number of replicas to all data, nev er changing thereafter, are not suitable. To this issue, we propose a two-layer geo-cloud based dynamic replica creation strategy called TGstag. TGstag addresses the issue with twofold: policy constraint heuristic inter-datacenter replication and load aware adaptive intra-datacenter replication. TGstag aims to minimize both cross-datacenter bandwidth consumption and average access time with constraints of policy and commodity node capacity. To evaluate the effectiveness of our strategy, we've conducted comprehensiv e experiments to compare TGstag with other approaches. The results show TGstag significantly reduces cross-datacenter bandwidth and ave rage read access time.
Hypotaurine and sulfhydryl-containing antioxidants reduce H2S toxicity in erythrocytes from a marine invertebrate (2008)

Hypotaurine (HT) has been proposed to reduce sulfide toxicity in some deep-sea invertebrates by scavenging free radicals produced from sulfide oxidation or by scavenging sulfide via the reaction of HT with sulfide, forming thiotaurine (ThT). We tested whether HT or several antioxidants could reduce the total dissolved sulfide concentration in buffered seawater exposed to H(2)S, and whether HT, ThT or antioxidants could increase the viability of Glycera dibranchiata erythrocytes exposed to H(2)S in vitro. We found that 5 and 50 mmol l(-1) HT reduced the dissolved sulfide in cell-free buffer exposed to H(2)S by up to 80% whereas the antioxidants glutathione ethyl ester (GEE), N-acetylcysteine (NAC), L-ascorbic acid (ASC), Tempol and Trolox had no consistent effect. Exposure of erythrocytes to 0.10%-3.2% H(2)S (producing 0.18-4.8 mmol l(-1) sulfide) decreased the fraction of viable cells, as evidenced by loss of plasma membrane integrity, with virtually no cells remaining viable at 1.0% or more H(2)S. Addition of HT (0.5-50 mmol l(-1)) significantly increased the fraction of viable cells (e.g. from 0.01 to 0.84 at 0.32% H(2)S) whereas ThT (0.5 and 5 mmol l(-1)) decreased cell viability. GEE (0.03-3 mmol l(-1)) and NAC (0.001-1 mmol l(-1)), which contain sulfhydryl groups, increased cell viability during H(2)S exposure but to a lesser extent than HT whereas ASC, Tempol and Trolox, which do not contain sulfhydryl groups, decreased viability or had no effect. These data show that HT can protect cells from sulfide in vitro and suggest that sulfide scavenging, rather than free radical scavenging, is the most important mechanism of protection.
Decrease of glucose in the human visual cortex during photic stimulation (1992)

Localized proton NMR spectroscopy was used to study cerebral metabolism in the visual cortex of healthy adults during rest and photic stimulation. Basal lactate levels showed considerable interindividual differences ranging from below detectability (less than 0.3 mM) to about 1 mM without consistent alteration during photic stimulation. Local brain glucose levels were significantly reduced (approximately 50%) during the entire period of photic stimulation and recovered to resting levels (approximately 0.8 mM) within 10 min after the end of stimulation. This decrease reflects the establishment of a new equilibrium due to enhanced delivery (blood flow) and enhanced consumption. The absence of lactate accumulation supports the hypothesis of a rapid efflux of lactate from brain tissue under activated conditions.
Combination Effects of Antifungal Nagilactones Against Candida albicans and Two Other Fungi with Phenylpropanoids (1993)

Antifungal activity of three nagilactones isolated from the root bark of Podocarpus nagi (Podocarpaceae), alone and in combination with a variety of phenylpropanoids, was investigated against three fungi, Candida albicans, Saccharomyces cerevisiae, and Pityrosporum ovale. Nagilactone E [2], the most abundant norditerpene dilactone, showed moderate to weak activity against these fungi. This activity was dramatically enhanced by several naturally occurring phenylpropanoids such as anethole [5] and isosafrole. For example, anethole enhanced the activity of nagilactone E as much as 128-fold for C. albicans, decreasing the MIC of this nagilactone from 800 to 6.25 micrograms/ml.
P‐24: Incorporation of Optiva Polarizers in LCD Production Line (2001)

Abstract A new concept of a production line for fabrication of LC displays with Optiva polarizers is discussed. Depending on LCD design the polarizer may be formed at diverse stages of the LCD process. A common approach and basic features of incorporation of new polarizer in LCD mass production are considered. Prototype equipment was fabricated and sample TN LC displays were produced to demonstrate the viability of this new technology.

Chiral discrimination with regioselectively substituted cellulose esters as chiral stationary phases (2000)

Four kinds of cellulose derivatives, including two regioselectively substituted cellulose esters (6-O-acetyl-2,3-di-O-benzoyl cellulose and 2,3-di-O-acetyl-6-O-benzoyl cellulose), were synthesized so that the effects of their functional group distribution on their chiral discrimination ability could be examined. The degree of substitution by functional groups appeared to have a critical effect on the separation in most cases, but the type of the functional group at the C-6 position also significantly influenced chiral discrimination when a series of neutral arylalcohol derivatives were used as racemates.

La nouvelle loi pénitentiaire. (2006)

En Belgique, la prison n’a jamais fait l’objet d’une législation spécifique. Depuis toujours, c’est le gouvernement qui organise l’administration pénitentiaire par voie d’arrêtés ou de circulaires, ce qui a alimenté les critiques jusqu’au niveau international. Une importante réforme a toutefois été entamée en 1996. Elle a abouti au vote de la loi de principes concernant l’administration pénitentiaire ainsi que le statut juridique des détenus (loi du 12 janvier 2005). L’élaboration de cette loi a pris dix ans, et ses arrêtés d’exécution ne sont pas encore publiés un an et demi après son adoption. Par-delà le temps donné aux experts et aux acteurs de terrain pour finaliser ce texte, et la complexité inhérente à la matière, ces délais reflètent aussi les blocages intervenus dans le processus, en particulier sous le gouvernement arc-en-ciel. Philippe Mary relate le processus d’élaboration de cette loi. Suivant en cela les experts les plus autorisés, il montre aussi que l’application de la loi risque de buter sur la persistance du problème de la surpopulation carcérale, ainsi que sur des résistances des agents pénitentiaires, aux yeux desquels les droits des détenus peuvent apparaître comme une remise en cause de leur manière de travailler. Dans ce contexte, et en l’absence d’une réforme de l’organisation interne des prisons et de la formation du personnel, l’objectif de limitation des effets préjudiciables de la détention, pivot de la loi repris à leur compte par le gouvernement et par l’administration, risque fort de ne pas être atteint.
Tuning the Coordination Number of Hydroxypyridonate-Based Gadolinium Complexes:  Implications for MRI Contrast Agents (2006)

Eight-coordinate hydroxypyridinone/terephthalamide GdIII complexes display high relaxivities due to their two inner sphere water molecules. This relaxivity can be further increased by functionalizing the terephthalamide moiety with an amine. A significant hydrogen bonding interaction between the amine and another water molecule close to the GdIII apparently facilitates its coordination on the open site of the metal. The resulting nine-coordinate complex has three inner sphere water molecules, while maintaining high stability and fast ligand exchange rates.

Consideration for Future Stimulation Options is Vital in Deciding Horizontal Well Drilling and Completion Schemes for Production Optimization (2006)

Abstract Thorough planning of a well, or better yet, a field, to determine how each well can provide maximum production throughout its lifetime is unquestionably very important to the operator. For fields of vertical wells, this process is well understood. For horizontal completions, however, only 20 years of practice are behind us. For lower permeability reservoirs, the theory that using horizontal wellbores can eliminate fracture stimulation has proven to be false. Today, the assumption that moderate to higher permeability reservoirs will never be candidates for stimulation is also being challenged by a high number of non-economic wells. Too often, we find many of these horizontal completions need stimulation but are not candidates because of the mechanical limitations of the completion plan. This paper discusses the many field and reservoir aspects, including formation geology and localized tectonics, that can influence proper well placement for future applications of fracture stimulation. The evaluation of emerging completion tools and processes that enable fracture stimulation should be nurtured to allow wells in less promising areas of the reservoir to become economic contributors and not net losses on the ledger. These wells must be incorporated into the general recovery plan for a field and taken into account in completion schemes (especially perforating techniques) to best produce the well when stimulation is not required, yet keeping stimulation as a future option. Different completion schemes may have to be used based on the position of the well within the field. Field experience with supporting data will be presented and discussed in depth, as well as conventional and new stimulation options that would optimize the specific applications.

New Strategy for the Conformational Analysis of Carbohydrates Based on NOE and <sup>13</sup>C NMR Coupling Constants. Application to the Flexible Polysaccharide of <i>Streptococcus mitis</i> J22 (1999)

For complex oligosaccharides, which are relatively rigid with modest excursions from a single minimum energy conformation, it is straightforward to build conformational models from NOE data. Other oligosaccharides are more flexible with transitions between distinct minima separated by substantial energy barriers. We show that modeling based on scalar coupling data is superior to NOE-based modeling for the latter case. Long range 13C-13C and 13C-1H coupling constants measured for the heptasaccharide repeating subunit of the cell wall polysaccharide from Streptococcus mitis J22 are correlated with individual glycosidic dihedral angles, effectively uncoupling the degrees of freedom of the oligosaccharide and allowing a search for combinations of dihedral angles which are energetically reasonable, i.e., with no bad van der Waals contacts, and which can be combined to satisfy all the measured J values. Allowed values of the individual angles can then be combined to search for overall oligosaccharide conformations which contribute to the ensemble. We show that while the polysaccharide from S. mitis J22 is flexible, requiring multiple conformations, most of the flexibility is localized to a few bonds and only a rather small number of conformations is required to reproduce the experimental NOE and scalar coupling data.
Poly(Vinyl Alcohol) Gate Dielectric Treated With Anionic Surfactant in C60 Fullerene-Based n-Channel Organic Field Effect Transistors (2016)

We report on the preparation and performance enhancement of n-type low-voltage organic field effect transistors (FETs) based on cross-linked poly(vinyl alcohol) (cr-PVA) as gate dielectric and C60 fullerene as channel semiconductor. Transistors were prepared using bottom-gate top-contact geometry and exhibited field-effect mobility (µFET) of 0.18 cm2V-1s-1. Treatment of the gate dielectric surface with an anionic surfactant, sodium dodecyl sulfate (SDS), passivates the positively charged defects present on the surface of cr-PVA, hence resulting in overall transistor performance improvement with an increase in µFET to 1.05 cm2V-1s-1 and additional significant improvements in dielectric capacitance, transistor on/off current ratio and transconductance.
R&D of CdTe-absorber photovoltaic cells, modules, and manufacturing equipment: plan and progress to 100 MW/yr (2002)

As part of a long-term vision of multi-GW production of photovoltaic (PV) panels per year, First Solar is implementing a plan for 17 kW/hour (/spl sim/100 MW/year for 3 shifts) production. The research and development of the cells, modules, and manufacturing equipment necessary for this level of production are discussed. A component of this plan is to raise module efficiencies to 10%, with the majority of improvement coming from (i) improvement of thin-film uniformity, and (ii) reduction of CdS layer thickness while protecting open-circuit voltage with the inclusion of a high-resistivity layer between the TCO and CdS layers. The operation of a new semiconductor deposition system at 2.9 m/sup 2//min, production throughput, and product quality are also discussed.
