Comparison of Cell-Based Biosensors with Traditional Analytical Techniques for Cytotoxicity Monitoring and Screening of Polycyclic Aromatic Hydrocarbons in the Environment (2009)

Abstract Today, special attention is paid to the environmental pollution effects of polycyclic aromatic hydrocarbons (PAHs), which are carcinogenic and mutagenic compounds. They are also widely distributed in the environment and can be found in water, soil, and plants. For this reason, various technologies have been developed to detect and screen for PAHs, and one of the recent developments is cell-based biosensors (CBBs). This type of sensor allows for real-time measurements by detecting the impedance of cellular behavior, which has been proven sensitive to toxic compounds. This articles presents a review of the previous work on CBBs for environmental monitoring of PAHs, in comparison with other conventional methods, which are based on chromatographic techniques and immunoassay.

Usage profiles for sustainable buildings (2010)

The ultimate goal of sustainable homes and buildings is to work towards energy efficiency automatically taking into account user comfort always acknowledging the residents' desires. Such environments demand for a friendly coexistence between technology and usability to assure an optimized reality in terms of comfort, economic and energy savings. The ThinkHome project is geared towards this mission. It aims at exploiting automation systems and mechanisms based on artificial intelligence to further improve the sustainability of buildings. ThinkHome is designed in a way to relieve the smart home inhabitants from cumbersome tasks such as readjustments of their preferences by introducing learning capabilities and context awareness in the home. Part of the ThinkHome project, this paper proposes an advanced use case for energy savings. It involves the necessity of defining usage profiles which help the underlying system to be aware about the stability of users' behaviors and perform its strategies always with sustainable goals in mind.
Device-oriented directed self-assembly of Lamellar microdomains from a block copolymer containing hybrid (2008)

Directed self-assembly (DSA) of a block copolymer containing hybrid material using topographic guiding patterns is presented in this paper. Lamellar microdomains of the hybrid material, which is a mixture of poly(styrene-b-ethylene oxide) (PS-b-PEO) and organosilicate (OS) precursor, have orientational correlation length about five times longer than typical organic block copolymers such as poly(styrene-b-methyl methacrylate) (PS-b-PMMA). The longer correlation length (i.e. bigger grain size) makes it possible to align the lamellar microdomain into geometries similar to device layouts. We report one-dimensional assembly of lamellar microdomains on substrates, which gives crossbar and multifinger nanostructures.
Molecular characterization of addiction systems of plasmids encoding extended-spectrum β-lactamases in Escherichia coli (2010)

In E. coli producing CTX-M-15 or CTX-M-9 ESBLs, plasmids bearing the bla(CTX-M) gene have multiple addiction systems that could contribute to their maintenance in host strains.
Anti-tumour effects of antibodies targeting the extracellular cysteine-rich region of the receptor tyrosine kinase EphB4 (2015)

EphB4 is a membrane-bound receptor tyrosine kinase (RTK) commonly over-produced by many epithelial cancers but with low to no expression in most normal adult tissues. EphB4 over-production promotes ligand-independent signaling pathways that increase cancer cell viability and stimulate migration and invasion. Several studies have shown that normal ligand-dependent signaling is tumour suppressive and therefore novel therapeutics which block the tumour promoting ligand-independent signaling and/or stimulate tumour suppressive ligand-dependent signaling will find application in the treatment of cancer. An EphB4-specific polyclonal antibody, targeting a region of 200 amino acids in the extracellular portion of EphB4, showed potent in vitro anti-cancer effects measured by an increase in apoptosis and a decrease in anchorage independent growth. Peptide exclusion was used to identify the epitope targeted by this antibody within the cysteine-rich region of the EphB4 protein, a sequence defined as a potential ligand interacting interface. Addition of antibody to cancer cells resulted in phosphorylation and subsequent degradation of the EphB4 protein, suggesting a mechanism that is ligand mimetic and tumour suppressive. A monoclonal antibody which specifically targets this identified extracellular epitope of EphB4 significantly reduced breast cancer xenograft growth in vivo confirming that EphB4 is a useful target for ligand-mimicking antibody-based anti-cancer therapies.
State of the art integrated millimeter wave passive components and circuits in advanced thin SOI CMOS technology on High Resistivity substrate (2006)

In this paper, a comparison between transmission line (TL) integrated in high resistivity (HR) silicon on insulator technology (SOI), standard CMOS and InP technologies is made. State of the art performances are reported on HR SOI with loss propagation of about 0.4 dB/mm@40 GHz and < 1 dB/mm@100 GHz. These results demonstrate that using HR SOI wafer suppressed substrate losses (like for III-V technology). In addition, model has been developed for the described TL. To illustrate these results two microwave passive circuits, a 80 GHz coupler and a 80-100 GHz band-pass filter with both 2.5dB insertion losses (for the HR SOI version) have been realized in standard bulk CMOS and HR SOI technologies for comparison and modelization purpose.
Practical partitioning for testability with time-shared boundary scan (2002)

The authors present a partitioning method for practical circuits composed of a mixture of very complex and very simple components. Specifically, attention is given to circuits containing a mixture of very complex devices, such as RAMs, and simple devices, such as basic states. A partitioning tool, PTOOL, that can be applied with equal effectiveness at the IC and PCB (printed circuit board) levels is introduced. The partitioning is influenced. in part, by the type (function) of components that make up the target circuit. Components requiring different test strategies are isolated in separate subsystems. PTOOL also forms subsystems such that the deepest embedded component can be accessed after a maximum of N gate levels. In addition, a number of 'good practice' partitioning criteria are incorporated. For example, under certain conditions. deeply embedded flip-flops can be easily tested by testing the surrounding circuits without the use of a scan chain. PTOOL recognizes such conditions and avoids unnecessary partitioning costs. Once the circuit is partitioned, each subsystem is accessed by an internal boundary scan. The boundary scan is centered around an input test bus and an output test bus, which are time-shared by the various subsystems. The time-shared architecture significantly reduces the amount of test serialization and test overhead.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Powerfiber for Flexible Fabric and Rigid Composite Applications (2003)

Abstract : ITN Energy Systems, Inc. (ITN), of Littleton, Colorado, has developed a power integrated fiber based material system for a variety of single fiber, flexible laminate and textile, and rigid composite applications, or combinations thereof. These materials, called PowerFibers, are the product resulting from the merging of solid-state, thin-film, lithium-based batteries onto fibrous substrates. Characteristic of solid-state, thin-film, lithium-based batteries are their inherent long lifetimes of up to 90,000 charge-discharge cycles at 100% depth-of-discharge. As a result, this battery technology with fiber reinforcement offers great promise in single fiber and multi-fiber composite material applications where both long battery and host device life is required. Individual PowerFibers can be incorporated into PowerComposites are multifunctional material systems including, for example, flexible woven or laminated composite articles for applications in wearable electronics, lightweight power integrated fabrics, and other flexible structures. Other PowerComposite applications include PowerFiber incorporation as power integrated structural reinforcement within, for example, rigid polymer matrix composites materials. ITN has developed a strong intellectual property position in PowerFiber and PowerComposite technologies. Ongoing work at ITN involves increasing the power capability and cycling current levels on an individual fiber and multi-fiber composite basis, investigating parallel and serial connections when cycling a network of PowerFibers and PowerComposites, and improvements relative to high volume production of PowerFibers and PowerComposites.

The synthesis of (Z)-penta-2,4-dien-1-ol and substituted (E)-pentadienols by the stereochemically controlled Horner–Wittig reaction (1991)

Acylation of Ph2P(O) Me with a lactone gives a Horner–Wittig intermediate with a Z-double bond protected as a Diels–Alder adduct with furan and hence (Z)-penta-2,4-dien-1-ol. Substituted (E)-penta-2,4-dien-1-ols are available by a more general route involving addition of enals to phosphine oxides, a regiochemically controlled allylic alcohol transposition, and a Horner–Wittig reaction. The geometry of only one double bond can be controlled.
The Impact of Contact Angle on the Biocompatibility of Biomaterials (2010)

Biomaterials may be defined as artificial materials that can mimic, store, or come into close contact with living biological cells or fluids and are becoming increasingly popular in the medical, biomedical, optometric, dental, and pharmaceutical industries. Within the ophthalmic industry, the best example of a biomaterial is a contact lens, which is worn by approximately 125 million people worldwide. For biomaterials to be biocompatible, they cannot illicit any type of unfavorable response when exposed to the tissue they contact. A characteristic that significantly influences this response is that related to surface wettability, which is often determined by measuring the contact angle of the material. This article reviews the impact of contact angle on the biocompatibility of tissue engineering substrates, blood-contacting devices, dental implants, intraocular lenses, and contact lens materials.
Development of 200 kV Scanning-Transmission Electron Microscope (1974)

In recent years, there has been increasing demand for higher voltage SEMs, in the field of surface observation, especially that of magnetic domains, dislocations, and electron channeling patterns by backscattered electron microscopy. On the other hand, the resolution of the CTEM has now reached 1 ∼ 2Å, and several reports have recently been made on the observation of atom images, indicating that the ultimate goal of morphological observation has beem nearly achieved.
Powerpath controller for fuel cell & battery hybridisation (2016)

Proton Exchange Membrane (PEM) fuel cells are a chemically fuelled power supply which generally have a higher energy density than Lithium-Polymer Battery (LIPOs) but a much lower power density. In order for PEM fuel cells to increase the endurance of an in-service battery power supply, without decreasing the peak power, it should be hybridised with a battery. It is key for the market that the overall switch to hybrid technology is low cost in terms of size, weight and money. Hybrid technology tends to be generically designed to suit any power system, using regulators to ensure voltage matching, and diodes to control the direction of electrical flow. Many electric motors are controlled by speed controllers which can regulate the thrust provided by the motor, accounting for fluctuations in voltage usually found in a depleting battery. Using diode and regulator based hybrids for electric motor applications is therefore inherently inefficient even if complicated synchronous DC–DC converters are used due to the increased cost, size and weight. This paper demonstrates the ability to use ideal diodes to control the flow of electricity through the hybrid and that voltage regulation is not needed for a motor in this case. Furthermore, this paper explores the natural balancing strategy created by duty cycling the PEM fuel cell to different points within it's polarisation curve, removing the requirement for DC–DC converters to match it to the battery voltage. The changes made improve the efficiency of the hybrid power electronics to over 97%.
Benefits and feasibility of the partial loading approach in cellular mobile radio systems (2000)

This paper analyzes the feasibility and potential benefits of following a novel design strategy for cellular systems known as partial loading. This strategy seeks low channel occupancy per cell at the capacity limit, as opposed to the high channel occupancy per cell of more conventional design strategies. By doing so, a considerable flexibility for the radio resource management is obtained, which can be exploited both to increase system capacity and to ease the accommodation of highly fluctuating traffic. A comprehensive system capacity analysis has been performed, based on an analytical model, and it is shown that the introduction of flexibility through partial loading has a capacity cost associated with it. However, it is shown that when that flexibility is properly exploited by adaptive radio link control techniques, such as link adaptation, frequency hopping, or call admission control policies, that cost is more than compensated for, making the partial loading approach a very attractive strategy for the evolution of current TDMA systems and the design of future ones.
Hepatocyte transplantation (2004)

Numerous laboratory studies have shown that hepatocyte transplantation may serve as an alternative to organ transplantation for patients with life-threatening liver disease. Because of the successes of experimental hepatocyte transplantation, institutions have attempted to use this therapy in the clinic for the treatment of a variety of hepatic diseases. Unfortunately, unequivocal evidence of transplanted human hepatocyte function has been obtained in only one patient with Crigler-Najjar syndrome type I, and, even then, the amount of bilirubin-UGT enzyme activity derived from the transplanted cells was not sufficient to eliminate the patient's eventual need for organ transplantation. A roadmap for improving patient outcome following hepatocyte transplantation can be obtained by a re-examination of previous animal research. A better understanding of the factors that allow hepatocyte integration and survival in the liver and spleen is needed to help reduce the need for repeated cell infusions and multiple donors. Although clinical evidence of hepatocyte function can be used to indicate function of transplanted hepatocytes, definitive histologic evidence is difficult to obtain. In order to assess whether rejection is taking place in a timely fashion, a reliable way of detecting donor hepatocytes will be needed. The most important issue affecting transplantation, however, relates to donor availability. Alternatives to the transplantation of allogeneic human hepatocytes include transplantation of hepatocytes derived from fetal, adult or embryonic stem cells, engineered immortalized cells, or hepatocytes derived from other animal species.
Coreference aware web object retrieval (2011)

As user demands become increasingly sophisticated, search engines today are competing in more than just returning document results from the Web. One area of competition is providing web object results from structured data extracted from a multitude of information sources. We address the problem of performing keyword retrieval over a collection of objects containing a large degree of duplication as different Web-based information sources provide descriptions of the same object. We develop a method for coreference aware retrieval that performs topic-specific coreference resolution on retrieved objects in order to improve object search results. Our results demonstrate that coreference has a significant impact on the effectiveness of retrieval in the domain of local search. Our results show that a coreference aware system outperforms naive object retrieval by more than 20% in P5 and P10.

Measurement of Serum Theophylline Concentrations Using a Modified Ames TDA® System (1983)

Results are presented which show that the Ames TDA Theophylline kit provides an accurate and reliable method of measuring the concentration of theophylline in plasma. It may be used with a shortened incubation time (5 min) without loss of accuracy, and a single calibration curve can be used over a 3-week period. There is an acceptable precision at all assayed levels (coefficient of variation, 3.3%) and results obtained for patients' samples correlate well with those obtained using liquid chromatography (y = 0.02 + 1.06x, r = 0.99) and enzyme immunoassay (y = 0.58 + 1.03x, r = 0.99).
Promising Prospects in Mobile Search: Business As Usual or Techno-Economic Disruptions? [Social Sciences] (2011)

It has taken more than a decade of intense technical and market developments for mobile Internet to take off as a mass phenomenon. And it has arrived with great intensity: an avalanche of mobile content and applications is now overrunning us. Similar to its wired counterpart, wireless Web users will continuously demand access to data and content in an efficient and user-friendly manner.
Systematic review: hepatic fibrosis – regression with therapy (2008)

The recent advances in anti-viral therapy have resulted in many reports on fibrosis and even on cirrhosis regression, especially early and in young people. A number of new agents have been suggested for the treatment of fibrosis, with promising results in animals; however, their efficacy in humans remains to be elucidated. The investigation of heterogeneity and plasticity of hepatic stellate cells is a topic of scientific interest and may result in improvements in patient management.
Severe combined immunodeficiency with abnormalities in expression of the common leucocyte antigen, CD45 (1997)

Children presenting with disseminated viral infections should be carefully investigated because they almost invariably have an underlying immunodeficiency. A child is reported who had disseminated cytomegalovirus and a novel form of severe combined immunodeficiency with abnormal expression of the common leucocyte antigen, CD45.
Vascular Effects of the Isomers of Mepivacaine (1972)

SUMMARY Two optical isomers of mepivacaine have been studied. LD50 in mice were the same with rapid intravenous injections. With slow intravenous or subcutaneous injections the D‐isomer was more toxic. With intracutaneous skin wheals and digital blocks in human volunteers the L‐isomer had the longest duration through a slower resorption of the drug from the tissue. The blood flow with subcutaneous injections was not changed but the permeability‐surface area product (PS) was higher when the D‐isomer was used. With intramuscular injections the local blood flow was higher when the D‐isomer was used. ZUSAMMENFASSUNG Zwei optische Isomere von Mepivacaine wurden untersucht. LD50 war bei der Maus bei schneller intravenoser Injektion gleich mit beiden Isomeren. Bei langsamen intravenosen oder subkutanen Injektionen war das D‐Isomer mehr toxisch. Bei intrakutanen Hautquaddeln und Fingerblockaden an homo ergab das L‐Isomer die liingste Anasthesiedauer durch eine verlangsamte Resorption dieser Droge in den Geweben. Bei subkutanen Injektionen wurde der Blutstrom an der Injektionsstelle durch wie Isomere nich, t verandert, doch war das Ober‐flachenprodukt des Permeabilitatsgebietes (PS) hoher wenn das D‐Isomer zur Anwendung kam. Bei intramuskularen Injektionen war der lokale Blutstrom hoher bei Verwendung des D‐Isomers.
Efficient support for partial write operations in replicated databases (2002)

We present a new replica control technique targeted at replicated systems in which write operations update a portion of the information in the data item rather than replacing it entirely. The existing protocols capable of supporting partial writes must either perform the writes on all accessible replicas of the data item, or always apply the writes to the same group (quorum set) of replicas. In the former case, the system incurs high message overhead. In the latter case, if any of the replicas in this group fail, additional replicas must be synchronously brought up-to-date during the write operation causing delay to the operation. Also, in both cases, the system loses the advantage of load sharing provided by replication. Our protocol avoids performing the write on all nodes while preserving load sharing and reducing greatly the risk of having to propagate updates synchronously. We describe the protocol, prove it correct, and present a comparative performance study of our protocol and the existing alternatives.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
