Utility of tris(4-bromopyridyl) europium complexes as versatile intermediates in the divergent synthesis of emissive chiral probes (2014)

The synthetic utility of europium complexes with three coordinated 4-bromopyridyl groups for chromophore elaboration has been assessed in palladium-catalysed Sonogashira coupling reactions, and in copper(i) mediated click reactions of the triazide derivative, generated in situ. The crystal structure of the Eu complex of a p-OMe-phenyl substituted triazole at 100 K is reported in which the pendant triazole sensitising moieties interdigitate in the solid-state lattice. The triazole complex can be separated into Δ and Λ enantiomers by chiral HPLC but is weakly emissive in methanol (ε 5.5 mM(-1) cm(-1); λexc 320 nm; ϕ 0.2%), contrasting with a set of four alkynyl-aryl derivatives which are one thousand times brighter and absorb strongly with broad absorption maxima in the range 332 to 360 nm. An enantiopure europium complex gives an intense CPL signal in solution that is the strongest yet reported.
Conjugate gradient eigenstructure tracking for adaptive spectral estimation (1995)

A conjugate gradient iteration is derived that converges to the set of r dominant/subdominant eigenpairs. This iteration is used to construct two eigenstructure tracking algorithms that track the r-dimensional dominant or subdominant subspaces of time-varying data or data-covariance matrices. The two eigenstructure tracking algorithms have update complexities O(m/sup 2/r) and the other O(mr/sup 2/), where m is the data dimension. The algorithms are customized to solve high resolution temporal and spatial frequency tracking problems. They are compared with existing techniques by tying into published simulation based performance tests. The algorithms demonstrate rapid convergence and tracking characteristics at a competitive cost.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Sydney coordinated adaptive traffic (SCAT) system philosophy and benefits (1980)

Sydney, Australia, just as many major cities in the world, has seen traffic movement become more and more congested despite capital expenditure on road construction and widening, on public transport systems, and on traffic management measures. SCAT, the coordinated adaptive traffic signal system, now being installed in Sydney, offers a substantial improvement to movement on arterial roads at low cost thereby enabling usage of the arterial road network to be optimized. An initial trial on a length of arterial road showed advantages in journey time over optimized fixed-time signal coordination of 35-39 percent in peak periods. SCAT is unique in that it consists entirely of computers and is totally adaptive to traffic demand. Its communication network provides extremely powerful yet flexible management of the system. The system, the system philosophy, and the benefits it is expected to yield are described. The benefits are not only in reduced delay, improved flow, and decreased congestion, but also in reduced accidents, lesser usage of petroleum resources, decreased air pollution, and improved residential amenity.

High-speed modulation of vertical-cavity surface-emitting lasers (1991)

The IM (intensity modulation) and FM (frequency modulation) characteristics of vertical-cavity surface-emitting lasers are studied. The laser has high FM efficiency and broad IM bandwidth (near 8 GHz) at a very low bias (4.5 mA). Five Gb/s pseudorandom direct intensity modulation of this laser with open eyes is demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
[Cranioplasty using computer-designed implants (preliminary report)]. (1995)

The co-operation among plastic surgeons and computer experts is presented demonstrating the reconstruction of a cranial bone defect of a patient. The adequacy of manufactured implant for reconstruction of cranial bone defect on the base of classic methods in only approximate. Computer aided design is needed for creating a more sophisticated implant. Cranial CT is digitised and a 3 dimensional model is created. The precise implant, manufactured by a computer directed milling machine, fits ino the bone defect. During the operation the cranial bone defect is explored, the bone edges are identified. The implant is fixed and the skull skin is closed. The authors demonstrate a successful operation of a cranial bone defect of 9 x 6.7 cm, the complicated shape and bone surface was reconstructed by a computer aided and manufactured implant. The co-operation of plastic surgeon and computer experts are essential during the process of implant design. The computer assisted and manufactured implants are suitable for the most sophisticated functional and aesthetic reconstruction of bone defect with complicated surface and irregular pattern.
Comparison of 3 Severity Criteria for <i>Clostridium difficile</i> Infection (2013)

Effective severity criteria are needed to guide management of Clostridium difficile infection (CDI). In this retrospective study, outcomes were compared between patients with mild-moderate versus severe CDI according to 3 different severity criteria: those included in the 2010 Society for Healthcare Epidemiology of America/Infectious Diseases Society of America guidelines, those from a recent clinical trial, and our hospital-specific guidelines.
Single-domain model for pseudo spin valve MRAM cells (1997)

The dynamic behavior of pseudo spin valve memory cells fabricated from GMR sandwich material with magnetic layers of differing thickness has been studied using a single domain model. The model takes into account torques within each magnetic layer as well as magnetostatic coupling between layers. When dynamic effects are included, the model predicts that inadvertent writing of a bit may occur during a read operation when the word field is pulsed on very quickly. Ramping up the word field over a period of several ns or increasing the thickness differential between the magnetic layers is shown to diminish the likelihood of an unintentional write.
Magnetic Resonance Imaging of the Upper Airway (1996)

In contrast to the traditional view that relaxation of the tongue causes airway obstruction, this study suggests that airway closure occurs at the level of the soft palate. Application of nasal CPAP can counteract an anesthesia-induced pharyngeal narrowing by functioning as a pneumatic splint. This is supported by the observed reduction in anteroposterior diameter at the level of the soft palate during propofol anesthesia and the subsequent increase in this measurement during nasal CPAP application.
TREATMENT OF MIXED INFECTIONS WITH PENICILLIN (1946)

In the course of our study of established infections during the past year and a half, it has been demonstrated frequently that penicillin is of questionable benefit or no benefit at all in the treatment of many infections in which there is a mixture of organisms. In some of these infections there is undoubtedly a synergistic action on the part of the bacteria in the production of the pathologic process. In other cases, secondary contaminants which are not pathogenic or are only feebly so, under ordinary circumstances, are able to multiply in the presence of wound exudate or dead tissue. Using the wound as a culture medium, these organisms produce metabolic products which may be toxic locally to the tissues of the wound or may be absorbed by the body and give rise to general symptoms. Certain of these metabolic products may also destroy the growth-inhibiting action of penicillin. Abraham
N-way fail-over infrastructure for reliable servers and routers (2004)

Maintaining the availability of critical servers and routers is an important concern for many organizations. At the lowest level, IP addresses represent the global namespace by which services are accessible on the Internet. We introduce Wackamole, a completely distributed software solution based on a provably correct algorithm that negotiates the assignment of IP addresses among the currently available servers upon detection of faults. This reallocation ensures that at any given time any public IP address of the server cluster is covered exactly once, as long as at least one physical server survives the network fault. The same technique is extended to support highly available routers. The paper presents the design considerations, algorithm specification and correctness proof, discusses the practical usage for server clusters and for routers, and evaluates the performance of the system.

Low-loss single-mode InP/InGaAsP waveguides grown by MOVPE (1987)

Losses as low as 0.4 ± 0.1 dB/cm for TE- and 0.65 ± 0.1 dB/ cm for TM-polarised light have been observed in tightly confined single-mode InP/lnGaAsP waveguides grown by MOVPE and processed using RIE. These are the lowest losses reported for InP-based waveguides. The structure could be used to make low-loss modulators for communications wavelengths.

Graph indexing based on discriminative frequent structure analysis (2005)

Graphs have become increasingly important in modelling complicated structures and schemaless data such as chemical compounds, proteins, and XML documents. Given a graph query , it is desirable to retrieve graphs quickly from a large database via indices. In this article, we investigate the issues of indexing graphs and propose a novel indexing model based on discriminative frequent structures that are identified through a graph mining process. We show that the compact index built under this model can achieve better performance in processing graph queries. Since discriminative frequent structures capture the intrinsic characteristics of the data, they are relatively stable to database updates, thus facilitating sampling-based feature extraction and incremental index maintenance. Our approach not only provides an elegant solution to the graph indexing problem, but also demonstrates how database indexing and query processing can benefit from data mining, especially frequent pattern mining. Furthermore, the concepts developed here can be generalized and applied to indexing sequences, trees, and other complicated structures as well.
Optimisation of DC and RF performance of GaAs HEMT-basedSchottky diodes (1999)

The authors show that in a GaAs HEMT-based monolithic millimetre-wave integrated circuit process flow, prior to gate metallisation, the introduction of a hydrofluoric acid cleaning process after gate recess etching results in a significant reduction in the Schottky diode turn-on voltage, series resistance and bias dependent RF junction resistance.
Preparation of Yeast RNA (1993)

This unit provides two protocols for extraction of RNA from yeast that differ primarily in the method for lysing the yeast cells. The first protocol isolates RNA directly from intact yeast cells by extraction with hot acidic phenol. This yields RNA that is relatively free of contaminating DNA, is convenient to perform with multiple samples, and gives little or no sample-to-sample variation. In contrast, an alternate protocol relies upon disruption of cells by vigorous mixing with glass beads and denaturing agents. Although this procedure results in efficient breaking of the cells, the product is associated with residual DNA, and the procedure itself is troublesome when one is working with multiple samples. A second alternate protocol describes the scaling up of the first two procedures to isolate enough total RNA for poly (A)+ RNA preparation.
Knockdown of Ebola Virus VP24 Impairs Viral Nucleocapsid Assembly and Prevents Virus Replication (2011)

The structural protein VP24 of Ebola virus (EBOV) is a determinant of virulence in rodent models and possesses an interferon antagonist function. In this study, we investigate the role of VP24 in EBOV replication using RNA interference by small interfering RNA to knock down the expression of this protein in virus-infected cells. We reveal that VP24 is required for assembly of viral nucleocapsids and that silencing of VP24 expression prevents the release of EBOV.
Celebrando la Constitución en las aulas infantiles (2002)

The circumsporozoite protein of the human malaria parasite Plasmodium falciparum contains multiple tandem repeats of the amino acid sequence Asn-Ala-Asn-Pro. The repeated sequence encompasses the immunodominant region of the protein, and antibodies raised against it are potent inhibitors of invasion and development of sporozoites in cultured hepatocytes. Using a modified build-up procedure, we have explored a large number of possible helical and near-helical conformations of a terminally blocked tetraicosapeptide, consisting of six repeats of the sequence Asn-Ala-Asn-Pro, and conclude that two helical conformations are energetically favored to the exclusion of all others. One of these conformations is longer, thinner, and left-handed and is likely to be adopted in nonpolar environments, while the other is shorter, broader, and right-handed and should be favored in aqueous solutions. We propose that the immunodominant region of the circumsporozoite protein of P. falciparum adopts one of these conformations in vivo.
Developing a pressure sensitive mat using proximity sensors for vital sign monitoring (2018)

This paper presents the concept, design and development of a novel flexible pressure sensitive mat using infrared proximity sensors and a compressible material layer. The system consists of sensors arranged in a matrix, on a flexible printed circuit board, covered with an elastic layer of silicone rubber including a cavity for each individual sensor. Finite element simulations suggest a linear deformation with increasing applied pressure. Experiments on a prototype implementation confirm these results and illustrate a linear response with low noise. Finally, it is demonstrated that the system is able to recover breathing rate, indicating its suitability for patient monitoring applications.

Reverse-phase high-performance liquid chromatographic assay of phospholipases: application of spectrophotometric detection to rat phospholipase A2 isozymes (1993)

This paper appraises an HPLC method for assaying phospholipase A2 (PLA2). The procedure is based on heptane-isopropanol-H2SO4 extraction of fatty acids released by the enzyme in the presence of margaric acid as an internal standard, and precolumn derivatization with 9-anthryldiazomethane. The derivatives of naturally occurring long-chain fatty acids were accurately determined by reverse-phase HPLC with ultraviolet detection at 254 nm; the fatty acids were identical with margaric acid in terms of their extraction efficiency in the presence or absence of a bile salt, reactivity with the labeling reagent, and molar extinction coefficients of their derivatives. HPLC conditions were optimized so as to separate the derivatives of palmitic and oleic acids completely within 7 min. The use of the 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoglycerol/cholate system as substrate proved useful for the sensitive detection of PLA2 activities in rat tissue homogenates. Distribution of immunoreactive pancreatic and group II phospholipases A2 was estimated from the degree of inhibition of enzyme activities by specific antibodies raised against either forms of phospholipase A2 isozymes. The results were consistent with those of immunoblot analyses.

Distributed joint optimization of traffic engineering and server selection (2010)

Internet service providers (ISP) apply traffic engineering (TE) in the underlay network to avoid congestion. On the other hand, content providers (CP) use different server selection (SS) strategies in the overlay network to reduce delay. It has been shown that a joint optimization of TE and SS is beneficial to the performance from both ISP's and CP's perspectives. One challenging issue in such a network is to design a distributed protocol which achieves optimality while revealing as little information as possible between ISP and CP. To address this problem, we propose a distributed protocol termed PETS, in which each router of ISP makes independent traffic engineering decision and each server of CP makes independent server selection decision. We prove that PETS can achieve optimality for the joint optimization of TE and SS. We also show that PETS can significantly reduce message passing and enables ISP to hide important underlay network information (e.g., topology) from CP. Furthermore, PETS can be easily extended to handle the case of multiple CPs in the network.
