Multicast in DKS (N,k,f )overlay networks (2005)

Recent developments in the area of peer-to-peer computing show that structured overlay networks implementing distributed hash tables scale well and can serve as infrastructures for Internet scale applications. We are developing a family of infrastructures, DKS(N; k; f), for the construction of peer-to-peer applications. An instance of DKS(N; k; f) is an overlay network that implements a distributed hash table and which has a number of desirable properties: low cost of communication, scalability, logarithmic lookup length, fault-tolerance and strong guarantees of locating any data item that was inserted in the system. In this paper, we show how multicast is achieved in DKS(N, k, f) overlay networks. The design presented here is attractive in three main respects. First, members of a multicast group self-organize in an instance of DKS(N, k, f) in a way that allows co-existence of groups of different sizes, degree of fault-tolerance, and maintenance cost, thereby, providing flexibility. Second, each member of a group can multicast, rather than having single source multicast. Third, within a group, dissemination of a multicast message is optimal under normal system operation in the sense that there are no redundant messages despite the presence of outdated routing information.
Application of Inflow Control Devices to Maximize Oil Recovery in a Vertical Multilayer Well, South China (2012)

Abstract In an offshore oil field in the southern East China Sea, the formations are sandstone and consist of six horizons, with specific flow unit characteristics and different aquifer support strengths. The operator intended to optimize the production with a permanent simple completion, in commingled production. However, the differences in reservoir properties and aquifer support presented a challenge for maximizing the oil recovery and delaying the water cut without resorting to well intervention. Passive inflow control device (ICD) technology was used to balance the influx from the different formations and hence maximize oil recovery while delaying the incremental water production, and production data validated the benefits of the application by showing a water cut of 50%, in contrast to the expected value of 90% (without the ICD completion), with the same estimated amount of cumulative oil production. Such a benefit is accrued by restricting fluid withdrawal from high-conductivity zones or with strong water drive, while providing enhancements to contribution from lower conductivity zones or zones with weaker water drive. This method is not new in itself, but it has not been used before in a permanent completion system where well interventions had not been planned. Multiple production iterations using numerical reservoir modeling of several completion options were performed and showed a 31.3% oil recovery improvement over the base scenario (all zones commingled without flow control devices).
An improvedJ-multiplied method for the measurement of3J(HN, Hα) from the two-dimensional15N-1H correlation spectrum (1999)

An improved method utilizing J-multiplication for the measurement of 3J(HN, Hα) coupling constant is introduced. The current method benefits from slower relaxation rate of heteronuclear multiple-quantum coherence. Furthermore, it combines incrementation periods for J-multiplication and 15N chemical-shift evolution. This reduces the length of the overall pulse sequence by t1. This, together with favourable relaxation properties of multiple-quantum coherence, leads to narrower linewidths in the F1 dimension relative to the previously presented sensitivity-enhanced, J-multiplied HSQC experiment. The method is demonstrated on human ubiquitin. Copyright © 1999 John Wiley & Sons, Ltd.

Occupational skin diseases in shipyard workers. (1983)

We have determined the prevalence of skin disorders in shipyard workers by means of an epidemiological cross-sectional study. Of 2057 employees answering a questionnaire, 16% reported present skin lesions. The employees in five chosen trades, altogether 355 persons, were seen by a nurse, who referred all cases of present skin lesions to a dermatologist for further examination. Occupational eczema was found in 11% of the 66 cleaners, 10% of the 94 carpenters, while no case was found among the 71 office workers. Of the 20 cases of occupational eczema, 5 were allergic and 15 irritant. The arms and legs were afflicted as commonly as the hands.

Results in a Smart Room setup are presented.
Biological Life Support System Demostration Facility: The Melissa Pilot Plant (2000)

MELISSA (Micro Ecological Life Support System Alternative) is a research project for the development of advanced life support systems, conducted by the European Space Agency. Its basic design is based on a loop of bioreactors with the main objective of the regeneration of the wastes generated by a crew into an edible material, with concomitant regeneration of the atmosphere for human respiration. The MELISSA Pilot Plant is a European facility to study and validate advanced life support systems. It has as main objectives the ground demonstration and characterization of a closed loop concept. This includes the development of the associated technology for its successful continuous operation such as water treatment, pathogen detection, food preparation, and other related items. At present time, the main research project developed in the Pilot plant is the MELISSA project. A key point in its development is the collection of experimental data under real operating conditions in order to perform mathematical modeling. This is a key issue in the approximation followed, both for the control and simulation of the individual bioreactors and the complete loop. The state of the art of the pilot plant is discussed, and particular emphasis is made in the description of the continuous operation of the interconnected bioreactors. Also the necessary associated research, required for its successful operation, such as the development of an advanced control system or the analysis of the effect of the malfunction of one compartment, on the subsequent ones are reviewed.
The sleeve monopole antenna in a warm plasma (1985)

Abstract A sleeve monopole antenna in a warm plasma with length almost the plasma wavelength has been analyzed in the frequency region where electron plasma waves exist. The current distribution and the input impedance have been obtained. When Landau damping is not considered, the current distribution is similar to that for a dipole and oscillates violently near the plasma frequency. It approaches a triangular shape as the frequency is increased. The input impedance varies considerably near the plasma frequency depending on the sleeve length. On the other hand, if Landau damping is taken into account, the amplitude of the oscillatory component of the current distribution becomes extremely small. For the input impedance, the effect of the sleeve beyond 25 times the Debye length can be neglected. This result agreed well with the measured input impedance values. It is found that the sleeve as the external conductor of the coaxial feeder has the effect of reducing the input impedance.
Direct Adhesion between Electroless Nickel-P Plated Metals and NBR Compounds during Curing (1997)

Abstract In this study, an examination was made of the various causative factors for the direct adhesion between nickel-P alloy (nickel alloy) and acrylonitrile-butadiene rubber (NBR) compounds during curing. In a high sulfur curing system (SV), direct adhesion was found to depend on time of exposure to air and not to occur after more than 48 h of exposure. In the peroxide curing system (PV), there was no adhesion at all regardless of the exposure time. The addition of triazine thiols to NBR compounds resulted in adhesion between NBR compounds and nickel alloy for exposures exceeding 48 h. Typical curing systems such as SV, low sulfur curing (LSV), sulfurless curing (SLV), and PV gave good NBR-nickel adherends when the NBR compounds contained the monosodium salt of triazine trithiol (TTN). In these system, peel strength in the adherends increased with triazine thiols, to a maximum, and then decreased. This parameter was influenced by the chemical structures of triazine thiols, such as those containing thiol(-SH) and the sodium salt of thiol (-SNa) groups, and by the exposure of nickel alloy to air. Peel strength decreased with the formation of nickel oxides on the surface. When the nickel oxides were removed from the nickel alloy surface, peel strength was recovered. High peel-strength adhesion between NBR compounds with TTN and nickel alloy is due to the formation of interfacial bonds and reinforcement layers at the adhesive interface during curing. Adherends consisting of NBR compounds with TTN and nickel alloy generally showed high heat resistance, oil resistance, and water resistance. The values for these parameters differed accordingly to the curing system and were optimal in the following order: SV < SV with TTN < PV with TTN.
Alpha-synuclein aggregation involves a bafilomycin A<sub>1</sub>-sensitive autophagy pathway (2012)

Synucleinopathies like Parkinson disease and dementia with Lewy bodies (DLB) are characterized by α-synuclein aggregates within neurons (Lewy bodies) and their processes (Lewy neurites). Whereas α-synuclein has been genetically linked to the disease process, the pathological relevance of α-synuclein aggregates is still debated. Impaired degradation is considered to result in aggregation of α-synuclein. In addition to the ubiquitin-proteasome degradation, the autophagy-lysosomal pathway (ALP) is involved in intracellular degradation processes for α-synuclein. Here, we asked if modulation of ALP affects α-synuclein aggregation and toxicity. We have identified an induction of the ALP markers LAMP-2A and LC3-II in human brain tissue from DLB patients, in a transgenic mouse model of synucleinopathy, and in a cell culture model for α-synuclein aggregation. ALP inhibition using bafilomycin A 1 (BafA1) significantly potentiates toxicity of aggregated α-synuclein species in transgenic mice and in cell culture. Surprisingly, increased toxicity is paralleled by reduced aggregation in both in vivo and in vitro models. The dichotomy of effects on aggregating and nonaggregating species of α-synuclein was specifically sensitive to BafA1 and could not be reproduced by other ALP inhibitors. The present study expands on the accumulating evidence regarding the function of ALP for α-synuclein degradation by isolating an aggregation specific, BafA1-sensitive, ALP-related pathway. Our data also suggest that protein aggregation may represent a detoxifying event rather than being causal for cellular toxicity.
Constraint Handling and Iterative Attribute Model Building in Decision-Based Engineering Design (1999)

Abstract This paper deals with two major issues that are central to the development and implementation of decision-based approaches to engineering design, namely, the treatment of constraints and accurate preference representation. In this paper, a decision analysis based constraint handling technique is introduced that will be particularly useful in constrained engineering problems with multiple attributes. Recognizing the iterative nature of engineering design where design alternatives may not always be known a priori (unlike in traditional engineering design), this paper introduces the concept of knowledge-influenced attribute model building as a means to update preference representation for the purposes of accurately reflecting designer’s intent and purposes throughout. the evolving design process. These two concepts are then used to extend the TRED (Trade-off based Robust Engineering Design) framework that has been developed as a formal design strategy through the integration of utility theory, based multiattribute models into a Taguchi philosophy based design of experiments setup. Here, to find robust optimal solutions to constrained engineering design problems, this paper presents the development of a second order design space reduction technique based on Response Surface Methodology (RSM). Its application to engineering problems is illustrated through a simple case study and the results are discussed.

[A long-term survivor of cT4 esophageal carcinoma treated via a multimodal approach - a case report]. (2014)

The patient was a 53-year-old man whose chief complaint was dysphagia. Pretreatment examination revealed 2 types of locally advanced esophageal squamous cell carcinoma at the middle to lower thoracic esophagus. A computed tomography (CT) scan showed a bulky primary tumor suspicious of aortic invasion and cardiac lymph node metastasis. The pretreatment diagnosis was cT4N2M0, cStageIVa. After induction chemotherapy with 5-fluorouracil (5-FU) and cisplatin (CDDP) (the FP regimen) according to the JCOG9907 regimen, subtotal esophagectomy and 2-field lymphadenectomy with retrosternal stomach roll reconstruction were performed. Intraoperatively, the primary tumor showed extensive and firm adhesion to the aortic wall. The postoperative diagnosis was pT4N0M0, pStageIII, RM1. Postoperative chemoradiotherapy (65 Gy+FP) was performed for the residual tumor at the aortic wall. The patient is alive without recurrences 4 years and 6 months after the esophagectomy. Downstaging of the tumor with induction chemotherapy and effective local control with surgery and postoperative chemoradiotherapy may have contributed to the patient's long-term survival. For multimodal treatment of cT4 esophageal cancer, an effective combination of chemotherapy, surgery, and chemoradiotherapy is essential to improve the treatment outcome.
Simultaneous observation of order and dynamics at several defined positions in a single acyl chain using deuterium NMR of single acyl chain perdeuterated phosphatidylcholines (1985)

Deuterium nuclear magnetic resonance (2H NMR) spectra from aqueous dispersions of phosphatidylcholines in which perdeuterated palmitic acid is esterified at the sn-1 position have several very useful features. The powder spectra show six well-resolved 90 degree edges which correspond to the six positions closest to the methyl end of the acyl chain. The spectral overlap inherent in the multiple powder pattern line shape of these dispersions can be removed by using a "dePaking" procedure [Bloom, M., Davis, J.H., & Mackay, A. (1981) Chem. Phys. Lett. 80, 198-202] which calculates the spectra that would result if the lipid bilayers were oriented in the magnetic field. This procedure produces six well-resolved doublets whose NMR properties can be observed without interference from the resonances of other labeled positions. The presence of a single double bond in the sn-2 chain increases the order of the saturated 16:0 sn-1 chain at every position in the bilayer compared with a saturated sn-2 chain at the same reduced temperature. Surprisingly, addition of five more double bonds to the sn-2 chain only slightly reduces the order of the 16:0 sn-1 chain at many positions in the bilayer compared with the single double bond. Calculating oriented spectra from a spin-lattice (T1) relaxation series of powder spectra allows one to obtain the T1 relaxation times of six positions on the acyl chain simultaneously. As an example of the utility of these molecules, we demonstrate that the dependence of the spin-lattice (T1) relaxation rate as a function of orientational order for two unsaturated phospholipids differs significantly from the corresponding fully saturated analogue. Interpreting this difference using current models of acyl chain dynamics suggests that the bilayers containing either of the two unsaturated phospholipids are significantly more deformable than bilayers made from the fully saturated phospholipid.
Fission of Iridium at Intermediate Excitation Energies (1968)

Cross sections have been determined radiochemically for 11 nuclides resulting from the fission induced in natural iridium (${\mathrm{Ir}}^{191,193}$) by 42.2-MeV ${\mathrm{He}}^{4}$ ions. The mass distribution was found to be symmetric with a full width at half-maximum of 23\ifmmode\pm\else\textpm\fi{}2 mass units. The average number of prompt neutrons emitted per fission event was 2\ifmmode\pm\else\textpm\fi{}1, and the total fission cross section was found to be 45\ifmmode\pm\else\textpm\fi{}11 \ensuremath{\mu}b.Total fission cross sections were determined at 13 different energies by a plastic-track technique. Analysis of the $\frac{{\ensuremath{\Gamma}}_{f}}{{\ensuremath{\Gamma}}_{n}}$ ratio, which is a measure of the competition between fission and neutron emission, indicates the fission threshold to be 22.3\ifmmode\pm\else\textpm\fi{}0.7 MeV and the fission level-density parameter to be ${a}_{f}=\frac{A}{10}$. These results are compared with similar data from the fission of other nuclei.
Recent patents in antifungal agent discovery (2008)

Background: Fungi are the most insidious pathogens, since they are eukaryotic microorganisms. Systemic infections are potentially fatal and are a growing danger for human health. There is increasing emergence of fungal resistance to currently available antifungal agents. Objective: An overview of the most relevant practical improvements in the field of antifungal drugs is given. Methods: A selection of the more interesting patents recorded from 2000 to 2007 is presented. Results/conclusion: Relevant news regarding azoles are the improvement of the solubility of known agents, and increased activity against Aspergillus species. Novel peptides, including echinocandins, are under study. Sordarins were analysed because they show a mechanism of action that confers on this class a high degree of selectivity. Natural products, macrolide derivatives and miscellaneous antifungals with interesting activities were described. Novel synthetic derivatives were reported as anti-Aspergillus agents. Finally, a description of compounds active on less explored targets is reported.
Polymer bulk homojunction light-emitting electrochemical cells (2006)

We report polymer light-emitting electrochemical cells (LECs) based on the in situ formation of thousands of micrometer-sized light-emitting p-n junctions within the bulk of the device. These “bulk homojunction” LECs, achieved by mixing metallic particles into the LEC film, exhibit dramatically improved electroluminescence (EL) output and response time. This is confirmed by EL intensity and absolute luminance measurements, which reveals an increase in quantum efficiency of more than tenfold, relative to a conventional single junction LEC of similar dimensions. The high performance of a bulk homojunction is attributed to its large specific emitting area. Further, we demonstrate red-, green-, and blue-emitting bulk homojunction LECs by using various combinations of luminescent polymers and metallic particles.

Tetraphenylarsoniumboranat liefert bei der 1:1‐Umsetzung mit (CH 3 ) 3 N · AlH 3 Triphenylarsin und (CH 3 ) 3 N AlH 2 BH 4 . Tetrabutylammonium‐, Tetraphenylphosphonium‐ und Tetraphenylarsoniumalanat entstehen aus den entsprechenden Boranaten durch doppelte Umsetzung mit LiAlH 4 .
Novel fabrication process of planar waveguides in rare-earth doped fluoroindate glasses (1995)

We report the successful fabrication of planar waveguides in rare-earth doped fluoroindate glass substrates. A new procedure for waveguide fabrication using a thermally evaporated AgF nonmetallic film was developed. The refractive index changes of more than 0.03, associated to low propagation losses achieved, open new perspectives and show the potentiality of using this glass family toward further developments in fabrication and design of integrated optical devices for optical communication wavelengths.
Mission Simulation Facility: Simulation Support for Autonomy Development (2004)

The Mission Simulation Facility (MSF) supports research in autonomy technology for planetary exploration vehicles. Using HLA (High Level Architecture) across distributed computers, the MSF connects users ’ autonomy algorithms with provided or third-party simulations of robotic vehicles and planetary surface environments, including onboard components and scientific instruments. Simulation fidelity is variable to meet changing needs as autonomy technology advances in Technical Readiness Level (TRL). A virtual robot operating in a virtual environment offers numerous advantages over actual hardware, including availability, simplicity, and risk mitigation. The MSF is in use by researchers at NASA Ames Research Center (ARC) and has demonstrated basic functionality. Continuing work will support the needs of a broader user base.
