Cultivation of human rotaviruses in cell culture (1984)

Sixteen specimens of faeces from children with acute diarrhoea due to rotavirus were inoculated into MA-104 cells. Rotaviruses present in six of the specimens were successfully adapted to growth after serial passage. Two of these strains had "short RNA" patterns and had caused epidemics of diarrhoea in children in Melbourne, Australia from 1977 to 1979, or in children in the Highlands of Papua New Guinea in 1979. The remaining four strains had "long RNA" patterns. One of these four strains was of major epidemiological importance as a cause of childhood diarrhoea in Melbourne during 1981. The other three strains appeared identical and were isolated from babies born in a Melbourne obstetric hospital during 1977. All six strains were successfully adapted to stationary culture, but only four strains could be plaqued . Selection of strains of rotavirus for culture on the basis of their known epidemiological importance in different communities will increase information about clinically important strains throughout the world.
Bacteriophage 82 gene Q and Q protein. Sequence, overproduction, and activity as a transcription antiterminator in vitro. (1987)

Phage 82 gene Q encodes a phage-specific positive regulator of late gene expression, thought, by analogy to the corresponding gene of phage lambda, to be a transcription antiterminator. We have cloned and sequenced the phage 82 gene Q and have overproduced and purified the 82 Q protein. We also have identified and sequenced DNA containing the phage 82 late gene promoter and terminator. We show that purified 82 Q protein is active and specific for DNA containing the 82 late gene promoter in a well defined in vitro transcription reaction: RNA polymerase initiating at the phage 82 late gene promoter and modified by 82 Q protein reads through a downstream transcriptional terminator. We used T1 RNase mapping to confirm that the putative readthrough RNA made in the presence of 82 Q protein is in fact an elongation product of the shorter RNA.
Preparation of an Enriched Fraction of Luteinizing Hormone-Secreting Cells from a Mixed Population of Rat Anterior Pituitary Cells1 (1993)

To determine whether female rat gonadotropes differentially secrete only LH, only FSH, or both LH and FSH, a new method of preparing an enriched fraction of LH-secreting cells from a mixed population of cells was developed. Dispersed female rat pituitary cells were incubated for 4 h in glass tubes with magnetic beads coated with anti-LH antibody. The tubes were then placed in a magnetic particle concentrator to separate cells bound to antibody-coated beads (518b7-bound) from the rest of the cell population (518b7-unbound). Several controls were used in this experiment: 1) mixed cells immediately plated without any preincubation (control); 2) mixed cells incubated without magnetic beads (incubated-only); 3) mixed cells incubated with magnetic beads but not separated (nonseparated); and 4) mixed cells first incubated with magnetic beads coated with normal mouse serum (NMS) and then separated into NMS-bound and NMS-unbound populations. After removal of magnetic beads from cell populations, the cells were plated at 200,000 cells/well. The 518b7-bound cells secreted 1.5-, 2-, 2-, and 5-fold more LH than control, incubated-only, nonseparated, or 518b7-unbound cells, respectively (p < 0.05); 518b7-bound cells secreted 2.5-, 3.8-, 3.8-, and 11-fold more FSH than control, incubated-only, nonseparated, and 518b7-unbound cells. The ratio of LH:FSH secreted did not vary between the different treatment groups, but the ratio of LH:FSH contained in 518b7-selected cells was greater than that for unbound cells. Our data indicate that we have prepared an enriched fraction of LH-secreting pituitary cells that also secrete FSH but have a greater capacity for producing LH than FSH in culture. These results are supportive of the view that LH and FSH are secreted by the same cells.
Persistence of Ebola virus in various body fluids during convalescence: evidence and implications for disease transmission and control (2016)

The aim of this study was to review the current evidence regarding the persistence of Ebola virus (EBOV) in various body fluids during convalescence and discuss its implication on disease transmission and control. We conducted a systematic review and searched articles from Medline and EMBASE using key words. We included studies that examined the persistence of EBOV in various body fluids during the convalescent phase. Twelve studies examined the persistence of EBOV in body fluids, with around 800 specimens tested in total. Available evidence suggests that EBOV can persist in some body fluids after clinical recovery and clearance of virus from the blood. EBOV has been isolated from semen, aqueous humor, urine and breast milk 82, 63, 26 and 15 days after onset of illness, respectively. Viral RNA has been detectable in semen (day 272), aqueous humor (day 63), sweat (day 40), urine (day 30), vaginal secretions (day 33), conjunctival fluid (day 22), faeces (day 19) and breast milk (day 17). Given high case fatality and uncertainties around the transmission characteristics, patients should be considered potentially infectious for a period of time after immediate clinical recovery. Patients and their immediate contacts should be informed about these risks. Convalescent patients may need to abstain from sex for at least 9 months or should use condoms until their semen tests are negative. Breastfeeding should be avoided during the convalescent phase. There is a need for more research on persistence, and a uniform approach to infection control guidelines in convalescence.
Damage Tolerance of P/M Turbine Disc Materials (1996)

The influence of heat treatments on the microstructure and mechanical properties of a powder metallurgy (P/M) turbine disc alloy MERL76, was studied. A damage tolerant microstructure (DTM) was designed for the alloy using a modified heat treatment (MHT) sequence. Comparisons of mechanical properties between the DTM and the conventional microstructure (CM) were made on the basis of tensile strength, low cycle fatigue (LCF) life, creep rupture life, and fatigue crack growth rates (FCGRs). The DTM significantly improved the creep rupture life (310 times) at 760C but resulted in a marginal loss. in tensile strength. The FCGR tests showed that FCGRs of the DTM at 700C were much lower than the CM material by a factor of 10 at a frequency of 0.15 Hz whereas the FCGRs at a frequency of 1 Hz were comparable over a wide range of AK values. The LCF lives of the two microstructures at 700C were also comparable.
Wireless uncompressed-HDTV-signal transmission system utilizing compact 60-GHz-band transmitter and receiver (2005)

A wireless uncompressed high-definition television (HDTV) signal transmission system utilizing a 60-GHz-band transmitter and two receivers is proposed and developed for indoor use. The system is capable of transmitting video signals with 1080i/720p formats and stereo audio signals as 1-Gb/s serial data stream. The compact transmitter and receiver are highlighted, each size of which is 50 mm /spl times/ 70 mm /spl times/ 15 mm. An output peak power of 10 mW and a minimum received power of -52 dBm are achieved. The wide-beam planar antennas allow less strict alignment for the wireless equipments with a maximum transmission distance of 7 m. Furthermore, path diversity technique is introduced to reduce the opportunities of shadowing by a human body around a television set.
On Constructing Efficient Shared Decision Trees for Multiple Packet Filters (2010)

Multiple packet filters serving different purposes (e.g., firewalling, QoS) and different virtual routers are often deployed on a single physical router. The HyperCuts decision tree is one efficient data structure for performing packet filter matching in software. Constructing a separate HyperCuts decision tree for each packet filter is not memory efficient. A natural alternative is to construct shared HyperCuts decision trees to more efficiently support multiple packet filters. However, we experimentally show that naively classifying packet filters into shared HyperCuts decision trees may significantly increase the memory consumption and the height of the trees. To help decide which subset of packet filters should share a HyperCuts decision tree, we first identify a number of important factors that collectively impact the efficiency of the resulted shared HyperCuts decision tree. Based on the identified factors, we then propose to use machine learning techniques to predict whether any pair of packet filters should share a tree. Given the pair-wise prediction matrix, a greedy heuristic algorithm is used to classify packets filters into a number of shared HyperCuts decision trees. Our experiments using both real packets filters and synthetic packet filters show that the shared HyperCuts decision trees consume considerably less memory.
Solving The Problem Of Local Interface Upconing In A Coastal Aquifer By The Method Of Small Perturbations (1968)

The problem of determining the shape of the rising interface is presented in connection with the withdrawal of fresh water by shallow wells operating a short distance above the freshwater salt-water interface in a coastal aquifer. The exact equations required for solving the problem of the moving interface are developed. Because of the nonlinear nature of the boundary condition along the interface, a linearized approximate solution based on the method of small perturbations is described as a tool for obtaining an analytical solution for cases involving small deviations of the interface from some initial or average steady one. Both two and three-dimensional cases are considered. The range of validity of the analytical results is verified by means of experiments in a sandbox model.
Comparison of In Vitro Activity of Cephalexin, Cephradine, and Cefaclor (1977)

Inhibitory activity of cephalexin, cephradine, and cefaclor was compared by the WHO-ICS agar dilution technique. Cefaclor was substantially more active against staphylococci, streptococci, gonococci, meningococci, Haemophilus, Escherichia coli, Klebsiella pneumoniae, Citrobacter diversus, Proteus mirabilis, salmonellae, and shigellae than was cephalexin, which in turn was more active than cephradine. Cefaclor appeared to be less resistant to staphylococcal penicillinase than did the other two agents. None of these cephalosporins was active against Enterobacter, Serratia, indole-positive Proteeae, Pseudomonas, or Bacteroides fragilis.
Recovery of very low intensity CCD images from noise (1989)

A scheme for detecting low-intensity images with a CCD (charge coupled device) camera is described in which successive images are digitized at fast frame rates and averaged to enhance the signal-to-noise ratio. The results demonstrate that a dynamic range in excess of 10000:1 can be obtained using an uncooled device and averaging times of 100 s, a sensitivity comparable to that obtained with cooled devices. The technique is illustrated by imaging the weak fluorescence produced by an ethidium bromide stained DNA electrophoresis gel.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Modeling of an IGBT and a Gate Unit (2013)

The purpose of this master thesis was to create a model of an IGBT in a single pulse test circuit and connect this model to a model of a Gate Unit. The IGBT model and the single pulse test circuit were both implemented in MATLAB and the Gate Unit was implemented in Simulink. The purpose of this model was to test the actions of the gate unit, so that the initial tuning could be done before going to the lab. Since no tests were performed in the lab, it was not possible to see how much of the testing that could have been done by simulations. However, the actions of the IGBT model much resembled the actions of the real component, even though some drawbacks were clear, such as the lack of tail current and tail voltage. These comparisons could be made between simulated characteristics and recordings from a previous test with the same component.
Translation, rotation and scale stabilisation of image sequences (2003)

Translation, rotation and scale stabilisation of image sequences is presented with phase correlation based estimation of motion parameters. Phase correlation and log-polar magnitude spectra representation is utilised to obtain translation, rotation and scale parameters. Stabilised frame positions are obtained through Kalman filtering of absolute parameters, and image frames are processed accordingly so as to result in a sequence that displays smooth global movements only.
Photochlorination of propane (1967)

Abstract The chlorination of propane was studied in a tubular flow reactor, with outside illumination, at atmospheric pressure. At chlorine concentrations of less than 1.5 mole % (and inert nitrogen above 94%) a second‐order (in chlorine) rate expression was indicated. At higher chlorine or propane concentrations propane affects the rate. Two rate equations, based upon different termination steps for the chain carriers, were found to fit the data. For the low concentration region the apparent activation energy for the overall reaction was 3.4 kcal./g.‐mole. Most of the measurements were carried out with polychromatic light, but data taken with a narrow band of radiation, over the range 2,200 to 5,400Ā, showed an increase in rate with decreasing wave length. As a first step toward reactor design, differential reactor data were used to predict the conversion for laminar flow, integral reactor conditions. A reactor model which included the effects of residence time distribution and radial variation in light intensity gave good agreement with experimental data. A plug‐flow model was less satisfactory.
DeepIaC: deep learning-based linguistic anti-pattern detection in IaC (2020)

Linguistic anti-patterns are recurring poor practices concerning inconsistencies among the naming, documentation, and implementation of an entity. They impede readability, understandability, and maintainability of source code. This paper attempts to detect linguistic anti-patterns in infrastructure as code (IaC) scripts used to provision and manage computing environments. In particular, we consider inconsistencies between the logic/body of IaC code units and their names. To this end, we propose a novel automated approach that employs word embeddings and deep learning techniques. We build and use the abstract syntax tree of IaC code units to create their code embedments. Our experiments with a dataset systematically extracted from open source repositories show that our approach yields an accuracy between 0.785 and 0.915 in detecting inconsistencies.
Barrières urbaines, politiques publiques et usages de l'hospitalité (2003)

Urban barriers, public policies and hospitality customs The legal and administrative barriers that protect established inhabitants against outsiders coming to settle did not disappear with fortifications and city tolls. Access to social housing, for example, is reserved for the poorly housed who have been residents for a number of years. Environmental associations are multiplying initiatives against projects for assistance centres. Hospitality shapes the conditions of sharing private space with a singular other, unlike public policies that define conditions of access for all, with the risk of excluding some among them.

A study of rib geometry for gas‐assisted injection molding (1996)

Abstract Large, thin, plate‐shaped parts usually are strengthened with structural ribs. Ribs also serve as gas channels with gas‐assisted technology. The layout and geometry of these gas‐channel ribs are critical to the gas‐assisted injection molding (GAIM) process. In this study, the effects of rib geometry, including aspect ratio and fillet geometry, on the GAIM process are investigated. Experimental results indicate that increasing the rib width widens the allowable operation range and thus improves the moldability. Adding fillets to the rib corner significantly enhances the moldability. Adding fillets also reduces the loss of rigidity due to void formation in the rib. A curved fillet improves moldability and rigidity more than one that is straight.
Dots and Incipients: Extended Features for Partial Fingerprint Matching (2007)

There are fundamental differences in the way fingerprints are compared by forensic examiners and current automatic systems. For example, while automatic systems focus mainly on the quantitative measures of fingerprint minutiae (ridge ending and bifurcation points), forensic examiners often analyze details of intrinsic ridge characteristics and relational information. This process, known as qualitative friction ridge analysis [1], includes examination of ridge shape, pores, dots, incipient ridges, etc. This explains the challenges that current automatic systems face in processing partial fingerprints, mostly seen in latents. The forensics and automatic fingerprint identification systems (AFIS) communities have been active in standardizing the definition of extended feature set, as well as quantifying the relevance and reliability of these features for automatic matching systems. CDEFFS (committee to define an extended feature set) has proposed a working draft on possible definitions and representations of extended features [2]. However, benefits of utilizing these extended features in automatic systems are not yet known. While fingerprint matching technology is quite mature for matching tenprints [3], matching partial fingerprints, especially latents, still needs a lot of improvement. We propose an algorithm to extract two major level 3 feature types, dots and incipients, based on local phase symmetry and demonstrate their effectiveness in partial print matching. Since dots and incipients can be easily encoded by forensic examiners, we believe the results of this research will have benefits to next generation identification (NGI) systems.
Overexpression of peroxiredoxin I and thioredoxin1 in human breast carcinoma (2009)

Prx I and Trx1 are overexpressed in human breast carcinoma and the expression levels are associated with tumor grade. The striking induction of Prx I and Trx1 in breast cancer may enable their use as breast cancer markers.
High-density multichip interconnect (HDMI) (2003)

The operating speeds of VHSIC II ICs require a systems approach to packaging wherein the chip and package must be characterized as a single entity. The package interconnects must be correctly matched to the chip in terms of impedance. The high-density multichip interconnect (HDMI) program is an approach to satisfying these requirements. The emphasis here is on the choice of substrate technology, but the total concept would not be viable without the developments in large ceramic packages, self-testing of ICs, and developments in large-scale multilayer routing programs. The rationale for using a polyimide dielectric is given. A detailed description of the HDMI approach is presented, covering the substrate, the signal dielectric, the interconnect and vias, and the base and package. Computer-aided design and testing are discussed, and the relationship of packaging density to functionality and performance is examined. Some of the constraints, problems, and areas that need further characterization are outlined. The tradeoffs allowed the production of useful circuits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Structural Basis of Gating by the Outer Membrane Transporter FecA (2002)

Siderophore-mediated acquisition systems facilitate iron uptake. We present the crystallographic structure of the integral outer membrane receptor FecA from Escherichia coli with and without ferric citrate at 2.5 and 2.0 angstrom resolution. FecA is composed of three distinct domains: the barrel, plug, and NH2-terminal extension. Binding of ferric citrate triggers a conformational change of the extracellular loops that close the external pocket of FecA. Ligand-induced allosteric transitions are propagated through the outer membrane by the plug domain, signaling the occupancy of the receptor in the periplasm. These data establish the structural basis of gating for receptors dependent on the cytoplasmic membrane protein TonB. By compiling available data for this family of receptors, we propose a mechanism for the energy-dependent transport of siderophores.
CD4 T cells play important roles in maintaining IL‐17‐producing γδ T‐cell subsets in naive animals (2011)

A proportional balance between αβ and γδ T-cell subsets in the periphery is exceedingly well maintained by a homeostatic mechanism. However, a cellular mechanism underlying the regulation remains undefined. We recently reported that a subset of developing γδ T cells spontaneously acquires interleukin (IL)-17-producing capacity even within naive animals through a transforming growth factor (TGF)β1-dependent mechanism, thus considered 'innate' IL-17-producing cells. Here, we report that γδ T cells generated within αβ T cell (or CD4 T cell)-deficient environments displayed altered cytokine profiles; particularly, 'innate' IL-17 expression was significantly impaired compared with those in wild-type mice. Impaired IL-17 production in γδ T cells was directly related to CD4 T-cell deficiency, because depletion of CD4 T cells in wild-type mice diminished and adoptive CD4 T-cell transfer into T-cell receptor β-/- mice restored IL-17 expression in γδ T cells. CD4 T cell-mediated IL-17 expression required TGFβ1. Moreover, Th17 but not Th1 or Th2 effector CD4 T cells were highly efficient in enhancing γδ T-cell IL-17 expression. Taken together, our results highlight a novel CD4 T cell-dependent mechanism that shapes the generation of IL-17+ γδ T cells in naive settings.

Comparison of Several Computerized Distribution Planning Methods (1985)

Modern computerized techniques for assisting in the planning of distribution systems include a wide range of computerized, automated design procedures. A number of different techniques are reviewed and tested in a uniform manner. Benefit, data, resources and sensitivity to a number of factors are all compared and reviewed. Guidelines for application and evaluation of need are developed.
A Meta-Analytic Examination of Basal Cardiovascular Activity in Posttraumatic Stress Disorder (2001)

EFFICIENT GREEN ELECTROLUMINESCENCE IN NITROGEN-DOPED GaP <i>p-n</i> JUNCTIONS (1968)

P–N junctions have been formed in GaP using the liquid-phase epitaxy process. In addition to the shallow donors and acceptors, nitrogen has been added to the grown layer to increase η, the room-temperature external quantum efficiency of the electroluminescence of the green emitting A line and its phonon replicas. The measured value of η was as high as 0.1% dc and 0.2% pulsed. The nonradiative processes are reduced by using sulfur rather than other shallow donors to fabricate the n side of the junction.
