Peer-to-Peer Prefix Tree for Large Scale Service Discovery (2008)

The problem studied in this thesis is the service discovery on platforms distributed at large scale, a service being a computing service (software components, scientific computing libraries, or binaries) offered with some characteristics and a performance level related to the hardware supporting it. Traditional approaches, designed for reliable and small scale environments, rely upon centralized solutions, unable to scale well in geographically distributed unreliable platforms. Our contribution centers around three main parts. 1) We propose a novel approach called DLPT (Distributed Lexicographic Placement Table), whose design is inspired by peer-to-peer systems. It calls upon an indexing system structured as a prefix tree. This structure supports multi-attribute range queries. 2) We study the mapping of nodes of this tree onto heterogeneous processors of the dynamic underlying network. We propose and adapt some load balancing heuristics for this kind of architectures. 3) Our architecture, targeted for platforms within which processors are unreliable and constantly joining and leaving the network, requires fault-tolerance mechanisms. Replication, usually used, is costly and unable to manage transient faults. We propose alternative best-effort mechanisms based on the self-stabilization theory for the construction and maintenance of prefix trees in a peer-to-peer environment. Among the mechanisms provided, one is proven to be snap-stabilizing. This means that the tree is rebuilt in an optimal time after an arbitrary number of faults. This approach is written in a coarse grain communication model and assumes several restrictions on initial topology handled, making it hard to implement on real platforms. To address these drawbacks, another self-stabilizing protocol is given for actual message-passing environments. Finally, we present a software prototype of this architecture and its first promising experiments on the Grid'5000 platform.
A homeodomain gene <i>Ptx</i> 3 has highly restricted brain expression in mesencephalic dopaminergic neurons (1997)

The mesencephalic dopaminergic (mesDA) system regulates behavior and movement control and has been implicated in psychiatric and affective disorders. We have identified a bicoid-related homeobox gene, Ptx3, a member of the Ptx-subfamily, that is uniquely expressed in these neurons. Its expression starting at E11.5 in the developing mouse midbrain correlates with the appearance of mesDA neurons. The number of Ptx3-expressing neurons is reduced in Parkinson patients, and these neurons are absent from 6-hydroxydopamine-lesioned rats, an animal model for this disease. Thus, Ptx3 is a unique transcription factor marking the mesDA neurons at the exclusion of other dopaminergic neurons, and it may be involved in developmental determination of this neuronal lineage.
Production of 1,2-Propanediol from Glycerol in Saccharomyces cerevisiae (2011)

Glycerol has become an attractive carbon source in the biotechnology industry owing to its low price and reduced state. However, glycerol is rarely used as a carbon source in Saccharomyces cerevisiae because of its low utilization rate. In this study, we used glycerol as a main carbon source in S. cerevisiae to produce 1,2-propanediol. Metabolically engineered S. cerevisiae strains with overexpression of glycerol dissimilation pathway genes, including glycerol kinase (GUT1), glycerol 3-phosphate dehydrogenase (GUT2), glycerol dehydrogenase (gdh), and a glycerol transporter gene (GUP1), showed increased glycerol utilization and growth rate. More significant improvement of glycerol utilization and growth rate was accomplished by introducing 1,2-propanediol pathway genes, mgs (methylglyoxal synthase) and gldA (glycerol dehydrogenase) from Escherichia coli. By engineering both glycerol dissimilation and 1,2-propanediol pathways, the glycerol utilization and growth rate were improved 141% and 77%, respectively, and a 2.19 g 1,2- propanediol/l titer was achieved in 1% (v/v) glycerolcontaining YEPD medium in engineered S. cerevisiae.
SPAM on the menu: the practical use of remote messaging in community care (2002)

This paper presents some early design work of the 'Digital Care' project, developing technologies to assist care in the community for user groups with different support needs. Our focus is on developing a SMS Public Asynchronous Messenger (SPAM) system for SMS messaging to a situated display in hostels for ex-psychiatric patients run by a charitable Trust. Such settings pose both methodological and design challenges. We face the methodological challenge to uncover requirements in such a sensitive domain by using ethnography, cultural probes and user workshops. The design challenge in this care setting is to provide support rather than new forms of dependence, and we report on early experiences of the deployed system.

Left Thoracotomy Reoperation for Coronary Artery Disease (1990)

Twenty patients underwent reoperative coronary artery bypass grafting (CABG) through a left thoracotomy since 1971. This was their second CABG in 16 patients, third in three patients and fourth in one patient. Surgery was performed from 1 to 16 years following the initial procedure. Demographic data showed no significant variation from patients undergoing standard reoperative CAGB in this institution. Ejection fraction varied between 30% and 73%. Cardiopulmonary bypass technic has gradually developed since 1971, using the left femoral artery and vein. For venous cannulation a 50-cm long catheter was positioned in the right atrium. Monitoring included pulmonary artery catheter with oximetry. Fibrillatory arrest of the heart was utilized with 18-33 degrees C core cooling cardioplegia. The left internal mammary artery (6) and reverse saphenous veins (44) were used for an average of 2.5 grafts per patient. The proximal anastomosis was placed on the descending thoracic aorta or the left subclavian artery. There were two early and no late deaths. Sixteen patients were restudied before discharge from the hospital with an early graft patency rate of 98% (41/42). The left thoracotomy approach may be preferable in selected cases of redo CABG. The danger of damage to the heart and patent grafts is greatly reduced.
Biotechnology of plasma proteins. Fractionation and applications. (1989)

Without discussing all of the current problems of industrial plasma fractionation, this INSERM International Symposium emphasized the importance of the technological progress of the last ten years. Although Cohn's classical technique of alcohol precipitation is still the most widely used, new techniques are rapidly being developed based on more selective methods with high extraction yields. However, it is certain that, given the growth in biotechnologies with the industrial applications of genetic engineering and cellular engineering, various problems will eventually be raised concerning plasma fractionation. It is probable that in the relatively near future certain fractions such as F VIII will no longer be prepared from plasma; but can the other fractions be reasonably replaced in the foreseeable future? Furthermore, the problems of purification will always be the crux of the development of biotechnologies. The technical committee of the OECD has recently drawn the attention of European governments to the considerable importance for the future of bioindustries of 'downstream processings' and the need to develop research on methods of extraction and purification. Human plasma is certainly the ideal model for the development of new methods of protein purification which could subsequently be applied to other industrial fields such as cellular engineering or genetic engineering. European countries definitely have an edge in this field as a result of their industries and fractionation centers.

B<sub>2</sub>O<sub>3</sub>: Grain boundary material for high-K<sub>u</sub> CoPt–oxide granular media with low degree of intergranular exchange coupling (2016)

Abstract The magnetic properties and structures of Co 80 Pt 20 –30 vol % oxide (ZrO 2 , Cr 2 O 3 , Y 2 O 3 , Al 2 O 3 , MnO, TiO 2 , WO 2 , SiO 2 , Mn 3 O 4 , WO 3 , Co 3 O 4 , MoO 3 , and B 2 O 3 ) granular media deposited at room temperature were investigated. As a result, the following were found. 1) By employing oxides with low melting point temperatures as the granular media, magnetic grains with high saturation magnetization ( ) and perpendicular magnetic anisotropy ( ) are obtained; the increases in and are due to the promotion of the columnar growth of magnetic grains and phase separation or two-phase precipitation between magnetic grains and oxides. 2) The increase in the of the granular media followed by the decrease in the melting point of oxides is due to the reduction in the amount of stacking faults. 3) Among these granular media, the CoPt–B 2 O 3 granular medium has the highest coercivity ( H c ) and ratio of H c to the magnetic anisotropy field ( ) of 8.0 kOe and 0.4, with and of 1115 emu/cm 3 and 1.1 × 10 7 erg/cm 3 , respectively. 4) The CoPt–B 2 O 3 granular medium has well-isolated and columnar growth magnetic grains with an average grain size of 6.5 nm.
Collaborative Online Video Watching (2009)

With the rise of broadband Internet, watching videos online has become a popular activity for millions of people. Many web sites encourage people to contribute, rate, and comment on video content, and more recently, to share their experiences with each other in real time. This dissertation explores the user experience of simultaneously chatting with other viewers while watching videos online. Watching a video and talking with others is a form of multitasking that reduces information processing quality. The first part of this dissertation examines distraction, enjoyment, and sociability in collaborative watching. In a series of field studies and laboratory experiments, I show that small groups of friends and strangers enjoy chatting while watching videos together, despite chat's distractive effects in both text and audio channels. The second part of this dissertation examines challenges of interacting with other viewers in large-scale broadcasts. I argue that viewers can chat with their friends and monitor the activities of the rest of the audience without feeling overwhelmed by using visual chat summaries and a social proxy representation of the audience. The final part of this dissertation shows how three types of information can be inferred about a video from the raw chat log data of groups that watched the video together: a set of tags that describe the video, ratings of the video, and a profile of peoples' enjoyment of each part of the video. This information can be used to improve the quality of video search and recommendation engines, and provide behavioral-based feedback on viewers' enjoyment to content creators. This dissertation provides new insight on the distraction from multitasking in an entertainment context. For the videos studied, it shows that although distraction does degrade information processing, it does not significantly harm the entertainment or social experience. This dissertation also provides concrete designs and recommendations for user interfaces for large-scale online video broadcasts. Finally, this dissertation demonstrates that information about a video that would be difficult or impossible to infer through a computer algorithm can be learned from the social interactions that occur as viewers watch together.
High resolution spatial transcriptome analysis by photo-isolation chemistry (2020)

ABSTRACT In multicellular organisms, individual cells are characterized by their gene expression profiles and the spatial interactions among cells enable the elaboration of complex functions. Expression profiling in spatially defined regions is crucial to elucidate cell interactions and functions. Here, we established a transcriptome profiling method coupled with photo-isolation chemistry (PIC) that allows the determination of expression profiles specifically from photo-irradiated regions of whole tissues. PIC uses photo-caged oligodeoxynucleotides for in situ reverse transcription. After photo-irradiation of limited areas, gene expression was detected from at least 10 cells in the tissue sections. PIC transcriptome analysis detected genes specifically expressed in small distinct areas of the mouse embryo. Thus, PIC enables transcriptome profiles to be determined from limited regions at a spatial resolution up to the diffraction limit.
Two Fuel Cell Cars In Every Garage? (2005)

In 1928, U.S. presidential candidate Herbert Hoover promised growing prosperity represented by “a chicken in every pot and two cars in every garage.” We now find ourselves at a point in history wondering if and when the power for those cars will come from fuel cells instead of internal combustion engines.
Incinerate your hazardous waste (1987)

Incineration is becoming a major method for final disposal of hydrocarbon-processing byproducts in petroleum refineries. Incineration alters the form of the organic materials, combining them with oxygen in the air to produce harmless carbon dioxide and water vapor. Inorganics in the waste must be further treated to ensure they do not reach the surrounding air or water. But there are acceptable technologies to process these byproducts of combustion. Plant incinerators are being designed to handle the total load of organic waste from the HPI. These systems can safely convert the previously hazardous waste materials to safe compounds. Combined with central waste treating systems to treat large quantities of plant aqueous wastes, the plants can reduce the equations for hazardous discharges dramatically. Operating units already demonstrate the capability.
Perfusion and chemical monitoring of living cells on a microfluidic chip (2004)

A microfluidic device that incorporates continuous perfusion and an on-line electrophoresis immunoassay was developed, characterized, and applied to monitoring insulin secretion from single islets of Langerhans. In the device, a cell chamber was perfused with cell culture media or a balanced salt solution at 0.6 to 1.5 microL min(-1). The flow was driven by gas pressure applied off-chip. Perfusate was continuously sampled at 2 nL min(-1) by electroosmosis through a separate channel on the chip. The perfusate was mixed on-line with fluorescein isothiocyanate-labeled insulin (FITC-insulin) and monoclonal anti-insulin antibody and allowed to react for 60 s as the mixture traveled down a 4 cm long reaction channel. The cell chamber and reaction channel were maintained at 37 degrees C. The reaction mixture was injected onto a 1.5 cm separation channel as rapidly as every 6 s, and the free FITC-insulin and the FITC-insulin-antibody complex were separated under an electric field of 500 to 600 V cm(-1). The immunoassay had a detection limit of 0.8 nM and a relative standard deviation of 6% during 2 h of continuous operation with standard solutions. Individual islets were monitored for up to 1 h while perfusing with different concentrations of glucose. The immunoassay allowed quantitative monitoring of classical biphasic and oscillatory insulin secretion with 6 s sampling frequency following step changes in glucose from 3 to 11 mM. The 2.5 cm x 7.6 cm microfluidic system allowed for monitoring islets in a highly automated fashion. The technique should be amenable to studies involving other tissues or cells that release chemicals.
The Normal Caliber of the Adult Female Urethra (1978)

The mean urethral caliber of 250 women undergoing cystoscopy to stage cancer of the cervix was 22F, as measured by the bougie à boule. A study of correlations between normal urethral caliber and age, weight, height, gravidity and parity of patients revealed a significant correlation with weight only.
Effects of fast routers advertisement on mobile IPv6 handovers (2004)

Mobile Ipv6 protocols are retrofit of mobility onto the next generation Internet (IPv6) protocols. Many of the original IPv6 protocols have inbuilt timing mechanisms which aim at ensuring fairness of access to media and signaling efficiency. The effects of these timers on mobile IPv6 traffic has been found to significantly affect application traffic on these networks. One proposal to remove unnecessary timers in neighbor discovery is called fast router advertisement (FastRA). This paper presents performance comparisons of FastRA with unmodified neighbor discovery in mobile IPv6 environments.
Cognitive Radio Networks Channel State Estimation Using Machine Learning Techniques (2019)

In interweave Cognitive Radio Networks (CRNs), monitoring the spectrum to detect unused portions (holes) is done by the spectrum sensing function however, it consumes both time and energy. So, some protocols use prediction to estimate the channel availability. One of these protocols use Hidden Markov Model (HMM) but in a very simple way. So, it does not perform well in several cases. In this paper, we propose two new protocols for cognitive radio channel availability prediction. Both protocols use HMM but in a more advanced way. They divide the data into two sets, thus create two HMM models. The first protocol uses Bayes theorem together with these two models, while the second one uses Support Vector Machine (SVM) with the two models HMM parameters. Evaluation of the two protocols proves that both protocols perform better than the old one that uses HMM in a classical way. It also proves that using SVM with HMM parameters is better than using HMM only. This is because dividing the data into two sets for training the protocols with, gives more flexibility to both protocols.
Cognitive rehabilitation for memory deficits following stroke (2007)

There was no evidence to support or refute the effectiveness of memory rehabilitation on functional outcomes, and objective, subjective, and observer-rated memory measures. There is a need for more robust, well-designed and better-reported trials of memory rehabilitation using common standardised outcome measures.
Earliest gestational age for fetal sexing in cell‐free maternal plasma (2003)

We conclude that real-time PCR of the SRY gene promises to be a reliable technique for early fetal sexing in maternal plasma.
Using Nanocomposite Coatings To Heal Surface Defects (2004)

Using computer simulations, we investigate the benefits of coating substrates that contain nanoscale defects with nanoparticle-filled polymer films. In particular, we focus on surfaces that contain a nanoscopic notch and use molecular dynamics (MD) simulations to determine the particle and polymer distribution on the damaged surface. The calculations reveal that a high volume fraction of relatively large particles are localized in the notch. Here, the polymer melt induces a depletion attraction between the particles and surface and thereby drives the nanoparticles into the defect. The time required for these relatively large particles to migrate to the notch is comparable to the time needed for the chains to move by approximately four radius of gyrations. The morphology obtained from the MD simulation serves as the input to the lattice spring model (LSM), which allows us to determine the mechanical properties of the nanocomposite-coated surface. The results show that the stress concentration at the notch tip is significantly reduced due to the presence of the nanoparticles. The application of such nanocomposite coatings could potentially yield defect-free surfaces that exhibit enhanced mechanical properties.
EVI-1 zinc finger protein works as a transcriptional activator via binding to a consensus sequence of GACAAGATAAGATAAN1-28 CTCATCTTC. (1995)

Previously, the DNA-binding consensus sequences for domains 1 (GACAAGATAAGATAA) and 2 (GAAGATGAG) of the EVI-1 protein were identified using GST fusion proteins of each domain in binding and amplification reactions. We have utilized full-length EVI-1 protein to confirm these consensus sequences and determine the spacial and orientation requirements for binding. Our data demonstrate that full-length EVI-1 can independently bind the consensus sequences in gel mobility shift assays. In binding and amplification reactions only the domain 1 consensus sequence (D1-CONS) was obtained with full-length EVI-1 protein. However, by using constructs in which D1-CONS was anchored, products were obtained in which the domain 2 consensus sequence (D2-CONS) was observed with the spacing and orientation of GACAAGATAATATAAN1-28 CTCATCTTC. Using this consensus sequence we show that EVI-1 can activate transcription from reporter constructs. No transcriptional activation was seen with the reporter construct containing D1-CONS alone while activation was seen with the construct-containing D2-CONS alone. These results indicate that the EVI-1 protein works as a transcriptional activator and the binding of the domain 2 with D2-CONS is essential for its activation.
Control of Texture in ZnO by Slip Casting in a Strong Magnetic Field and Heating (2002)

Abstract Anisotropic susceptibilities of feeble magnetic ceramics such as zinc oxide are quite small; therefore, it had been difficult to control the textured microstructures of these ceramics using a magnetic field. However, fabrication of the textured ZnO is achieved by slip casting in a strong magnetic field followed by heating. After the stable suspension of ZnO fine particles was compacted by slip casting in a strong magnetic field, a green body with a slight degree of crystalline texture was obtained. Densification and the grain growth enhanced the degree of texture during the sintering.
Auger depth profiling of MNOS structures by ion sputtering (1977)

Auger electron spectroscopy has been used in conjunction with argon-ion sputtering to study the morphology and chemical nature of MNOS structures. We find that a typical thin "oxide" in a memory device is a silicon oxynitride with about equal parts nitrogen and oxygen. The transition from nitride to "oxide" to silicon is a smooth one, with an oxide width of about 2.5-nm FWHM.
