Providing secure and accountable privacy to roaming 802.11 mobile devices (2012)

Nowadays, roaming individuals require ubiquitous, effortless, secure and private "on-the-go" connectivity for their Mobile Device (MD). At the same time, WiFi Access Networks (ANs) need to offer connectivity to MDs in an accountable and credible manner to avoid compromising their security policies. Our approach efficiently satisfies these conflicting requirements, and presents a solution where the MD does not have to disclose its identity when requesting network access. At the same time, the AN has a uniquely identifying alias for the MD, to account and profile for the connectivity it provides to it. The evaluation of our implementation on a live experimental testbed, demonstrates that our solution's overhead is remarkably low for the benefits it provides, and highlights its applicability and efficiency for real world deployment in the current Internet infrastructure.
DWT-Based Detection and Transient Power Direction-Based Location of High-Impedance Faults Due to Leaning Trees in Unearthed MV Networks (2008)

Electrical faults due to leaning trees are common in Nordic countries. This fault type has been studied in and it was found that the initial transients in the electrical network due to the associated arc reignitions are behavioral traits. In this paper, these features are extracted using the discrete wavelet transform (DWT) to localize this fault event. Wireless sensors are considered for processing the DWTs on a residual voltage of different measuring nodes that are distributed in the network. Therefore, the fault detection is confirmed by numerous DWT processors over a wide area of the network. The detection security is also enhanced because the DWT responded to a periodicity of the initial transients. The term for locating the faulty section is based on the polarity of a specific frequency bandpower computed by multiplying the DWT detail coefficient of the residual current and voltage at each measuring node. The fault due to a leaning tree occurring at different locations in an unearthed 20-kV network is simulated by the alternate transients program/electromagnetic transients program and the arc model is implemented using the universal arc representation. Test cases provide evidence of the efficacy of the proposed technique.
Colorectal cancer stem cell and chemoresistant colorectal cancer cell phenotypes and increased sensitivity to Notch pathway inhibitor (2015)

Colorectal cancer stem cells (Co-CSCs) are a small subpopulation of tumor cells which have been proposed to be tumor-initiating cells in colorectal cancer (CRC) and to be implicated in resistance to standard chemotherapy. Chemoresistance is a common problem in the clinic. However, the interrelation between Co-CSCs and chemoresistant cells has yet to be elucidated. The present study investigated the Co-CSC phenotype in colonospheres and chemoresistant CRC cell lines and aimed to identify targets for therapy. Colonospheres and chemoresistant CRC cells were found to be enriched with the CSC markers CD133 and CD44, and exhibited similar phenotypes. Furthermore, it was found that Notch signaling may simultaneously regulate Co-CSCs and chemoresistant cells and may represent a novel strategy for targeting this pathway in CRC.

Corticosteroid treatment as a risk factor for invasive aspergillosis in patients with lung disease. (1991)

Invasive pulmonary aspergillosis usually occurs in severely immunocompromised or neutropenic patients. Six patients with invasive aspergillosis are described whose only defence impairment was underlying lung disease and corticosteroid treatment. Cough, fever, and sputum production were the usual reasons for presentation and four patients developed the sepsis syndrome. Radiographic findings included de novo cavitation in three patients and rapid radiographic progression in four. Aspergillus species were isolated from respiratory secretions of all patients early in the course of the disease. Treatment was effective in only two patients and the subsequent progress of the others was consistent with a chronic necrotising process. Invasive pulmonary aspergillosis is uncommon in patients with respiratory diseases receiving corticosteroids, but should be considered when pneumonia and cavitary infiltrates occur.
Metabolism of Organic Substances in Anaerobic Phase of Biological Phosphate Uptake Process (1992)

Biochemical mechanisms of anaerobic uptake of organic substrate by anaerobic-aerobic activated sludge were investigated experimentally. As the organic polymers stored in the cell, 3H2MB and 3H2MV were newly identified besides PHB and PHV. Conceptual pathways for the formation of PHA (polyhydroxyalkanoates) were postulated. It was suggested that the conversion of glycogen into PHA should be important for the mechanisms of biological excess phosphate removal.
Localization and Mapping for Autonomous Navigation in Outdoor Terrains : A Stereo Vision Approach (2007)

We consider the problem of autonomous navigation in unstructured outdoor terrains using vision sensors. The goal is for a robot to come into a new environment, map it and move to a given goal at modest speeds (1 m/sec). The biggest challenges are in building good maps and keeping the robot well localized as it advances towards the goal. In this paper, we concentrate on showing how it is possible to build a consistent, globally correct map in real time, using efficient precise stereo algorithms for map making and visual odometry for localization. While we have made advances in both localization and mapping using stereo vision, it is the integration of the techniques that is the biggest contribution of the research. The validity of our approach is tested in blind experiments, where we submit our code to an independent testing group that runs and validates it on an outdoor robot
Selective Cloning of a Defined Number of Tandem DNA Repeats in Escherichia Coli (1996)

Repetitive DNA sequences play an important role in biology, especially at the level of eucaryotic gene transcription control. Their construction, assembly and cloning by conventional means or by PCR derived methods is usually very cumbersome. This method is based on the association of a small DNA tag with the sequence to be polymerised. The multimeric sequence is constructed in a stepwise manner, the tag allowing for simple in vivo selection of the (n+1) polymer containing vector at each step. Thus, n rounds of cloning generate a family of vectors, each harbouring a defined number of ordered tandem copies of the sequence of interest, ranging from 1 to n. Contrary to the multimerization methods based on PCR, this method is independent of the size of the sequence to be polymerised. It is, in fact, especially well suited for the moderate polymerisation of short DNA sequences such as regulatory proteins binding sites, or the preparation of small size DNA ladders. The outline of the method is as follows (Fig. 1). The sequence to be polymerised is first cloned between two compatible ends restriction sites in a cloning vector (sites A and B), generating vector 1X. Then, a small cassette encompassing an amber suppressor tRNA gene with its promoter and transcription terminator is cloned next to it (between sites C and D), to obtain vector 1X+S which is used to transform an amber mutated strain, such as, for example, XAC-1 (1). The 2X+S vector is obtained by cutting out the 1X+S fragment with restriction enzymes A and D, and cloning it between sites B and D of vector 1X. Growth of the transformants on minimal medium ensures that only the correct construct is selected for. In the same manner, the 3X+S vector is obtained by cloning the 2X+S A/D fragment into the 1X vector between the B and the D sites and selecting the transformants for the presence of the suppressor gene. The 3X+S vector will thus contain three adjacent copies of the sequence of interest, in the same orientation, between two unique restriction sites A and B, as the sites between the copies are destroyed by the cloning procedure and the asymmetrical cloning ensures that only one orientation of the sequence is inserted. Each time the cloning step is repeated, one unit of the sequence is added to the polymerised sequence. With a recombination deficient amber mutated strain as a host for the successive transformations, the limit to the number of copies of the sequence of interest is only given by the size of the plasmid. If the nX+S containing vector is destroyed by additional restriction cuts when preparing the nX+S fragment, then no purification of this fragment is required before cloning, and the successive rounds of cloning are very simple. Figure 1. Outline of the method. A and B are compatible ends restriction sites such as SalI and XhoI for example.

Transactive Control of Commercial Buildings for Demand Response (2016)

Transactive control is a type of distributed control strategy that uses market mechanisms to engage self-interested responsive loads to achieve power balance in the electrical power grid. In this paper, we propose a transactive control approach of commercial building heating, ventilation, and air-conditioning (HVAC) systems for demand response. We first describe the system models, and identify their model parameters using data collected from systems engineering building (SEB) located on our Pacific Northwest National Laboratory campus. We next present a transactive control market structure for commercial building HVAC systems, and describe its agent bidding and market clearing strategies. Several case studies are performed in a simulation environment using building controls virtual test bed (BCVTB) and calibrated SEB EnergyPlus model. We show that the proposed transactive control approach is very effective at peak shaving, load shifting, and strategic conservation for commercial building HVAC systems.
A role for sugar transporters during seed development: molecular characterization of a hexose and a sucrose carrier in fava bean seeds. (1997)

To analyze sugar transport processes during seed development of fava bean, we cloned cDNAs encoding one sucrose and one hexose transporter, designated VfSUT1 and VfSTP1, respectively. sugar uptake activity was confirmed after heterologous expression in yeast. Gene expression was studied in relation to seed development. Transcripts were detected in both vegetative and seed tissues. In the embryo, VfSUT1 and VfSTP1 mRNAs were detected only in epidermal cells, but in a different temporal and spatial pattern. VfSTP1 mRNA accumulates during the midcotyledon stage in epidermal cells covering the mitotically active parenchyma, whereas the VfSUT1 transcript was specific to outer epidermal cells showing transfer cell morphology and covering the storage parenchyma. Transfer cells developed at the contact area of the cotyledonary epidermis and the seed coat, starting first at the early cotyledon stage and subsequently spreading to the abaxial region at the late cotyledon stage. Feeding high concentrations of sugars suppressed both VfSUT1 expression and transfer cell differentiation in vitro, suggesting a control by carbohydrate availability.
Gurney Flap Experiments on Airfoils, Wings, and Reflection Plane Model (1998)

The effect of Gurney e aps on two-dimensional airfoils, three-dimensional wings, and a ree ection plane model were investigated. There have been a number of studies on Gurney e aps in recent years, but these studies have been limited to two-dimensional airfoil sections. A comprehensive investigation on the effect of Gurney e aps for a wide range of cone gurations and test conditions was conducted at Wichita State University. A symmetric NACA 0011 and a cambered GA (W)-2 airfoil were used during the single-element airfoil part of this investigation. The GA (W)-2 airfoil was also used during the two-element airfoil study with a 25% chord slotted e ap dee ected at 10, 20, and 30 deg. Straight and tapered ree ection plane wings with natural laminar e ow (NLF) airfoil sections were tested for the three-dimensional wing part of this investigation. A fuselage and engine were attached to the tapered NLF wing for the ree ection plane model investigation. In all cases the Gurney e ap improved the maximum lift coefe cient compared to the baseline clean cone guration. However, there was a drag penalty associated with this lift increase.
Antibacterial Action of Glycine on E. coli in the Presence of Ethanol (1999)

The antibacterial action of glycine and some derivatives on E. coli was investigated in the presence of ethanol. (1) The growth of E. coli was inhibited by glycine and slightly by alanine, but not by glycinamide or sarcosine. (2) The activity of glycine was strong at low temperature (20°C) or at alkaline pH (pH 9.0), and weak at high temperature (40°C) or at acidic pH (pH 5.0). (3) Synergistic action of glycine and ethanol was observed. (4) E. coli cells were injured by glycine and/or ethanol, and their ability to form colonies on deoxycholate agar was lost. However, the colony-forming ability of the injured cells was restored by incubation in recovery broth. (5) Though the respiratory activity of the cells was inhibited by treatment with these chemicals, this activity was also restored when the injured cells were incubated in suitable broth. However, the mode of recovery of respiratory activity of the cells may be different from that of the colony-forming ability.
Altered Dynamics of Action Potential Restitution and Alternans in Humans With Structural Heart Disease (2005)

There are marked differences in the dynamics of APD restitution and alternans in the ventricular myocardium of patients with SHD compared with patients without SHD. These differences may contribute importantly to cardiac electrical instability in diseased human hearts and may represent a promising target for antiarrhythmic substrate modification.
Spectral image complexity estimated through local convex hull volume (2010)

Most spectral image processing schemes develop models of the data in the hyperspace by using first and second order statistics or linear subspace geometries applied to the image globally. However, it is simple to show that the data are typically not multivariate Gaussian or are not well defined by linear geometries when considering the entire image, particularly as the spatial resolution improves and the scene becomes more cluttered. Here, we use the concept of a convex hull that encloses the data to rank local regions within an image by an estimate of their complexity. The complexity as defined here is directly related to the volume of the hull in n dimensions that encloses the data under the assumptions that less complex data will have fewer distinct materials and more complex data will have more materials. They will also be more widely separated in the hyperspace. The method uses the Gram Matrix approach to estimate the volume of the hull and is applied to an image that has been tiled. The complexity of each tile is then estimated showing the relative changes in complexity over a large area spectral image. Results will be shown for reflective hyperspectral imagery over different scene contents with resolutions of ≈2-3 m. Ultimately this methodology can be used to develop localized models of an image and may provide insight into the large area search problem.
Are nurses knowledgeable in regards to latex allergy? (1998)

Lack of knowledge concerning latex allergy may lead to a life-threatening adverse reaction to natural rubber latex. Registered nurses need a latex allergy knowledge base to provide latex-safe health care to clients and to create a latex-safe environment. This research explored the current knowledge base of registered nurses as related to (1) the care of clients at risk for latex allergy, or diagnosed with latex allergy, and (2) the provision of a latex-safe environment for all populations. This article describes this research and its implications for nurses. A copy of the Latex Allergy Knowledge Base Self-Assessment Questionnaire is included at the conclusion of the article.
Observer-based weighted predictive control (2003)

Two alternative algorithms for M.J. Grimble's (1990) basic weighted predictive control (WPC) are proposed. Limitations and advantages of each algorithm are examined. A generalized version of the basic WPC law is also presented. Simulations show the effects of design parameter such as prediction horizons and auxiliary filters on plant response and the effects of the disturbance model on the disturbance attenuation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Simultaneous suppression of Erk and Akt/PKB activation by a Gab1 pleckstrin homology (PH) domain decoy. (2003)

These results illustrate that the Gab1 PH domain is a potential target for antagonizing ErbB activation and PTEN inactivation, and for suppression of ErbB-induced metastatic activities in breast cancer cells.
Automatic Control of Cylinder by Cylinder Air-Fuel Mixture Using a Proportional Exhaust Gas Sensor (1994)

<div class="htmlview paragraph">Cylinder to cylinder air-fuel imbalance in an engine due to geometrical factors and component tolerances may be overcome by a system capable of individually controlling the air-fuel ratio for each cylinder. A stable feedback controller for individual cylinder air-fuel ratio was designed using dynamic models of the gas transport process and the proportional exhaust gas sensor (UEGO). The controller was tested using a proportional exhaust gas sensor located in each bank of a V6 engine. Preliminary test results indicate that automatic balancing of the air-fuel ratio to each cylinder can reduce carbon monoxide emissions compared to a feedback system controlling overall air-fuel ratio.</div>
Twisted Blood Vessels: Symptoms, Etiology and Biomechanical Mechanisms (2012)

Tortuous arteries and veins are commonly observed in humans and animals. While mild tortuosity is asymptomatic, severe tortuosity can lead to ischemic attack in distal organs. Clinical observations have linked tortuous arteries and veins with aging, atherosclerosis, hypertension, genetic defects and diabetes mellitus. However, the mechanisms of their formation and development are poorly understood. This review summarizes the current clinical and biomechanical studies on the initiation, development and treatment of tortuous blood vessels. We submit a new hypothesis that mechanical instability and remodeling could be mechanisms for the initiation and development of these tortuous vessels.
Stabilization of cubic CrN0.6 in CrN0.6/TiN superlattices (1998)

A transmission electron microscopy study of CrN0.6/TiN superlattices deposited by reactive magnetron sputtering is described. The stable structure of CrN0.60 is hexagonal, but high resolution transmission electron microscopy images of the superlattices showed that CrN0.6 layers ⩽10 nm thick were cubic, while 50 nm thick layers were hexagonal. That is, the cubic CrN structure was “epitaxially stabilized” by the cubic TiN, with which there is a 2.4% lattice mismatch. The superlattices with hexagonal CrN0.6 showed high strains and defect densities within ≈5 nm of each interface, presumably due to the 5.4% volume decrease associated with the cubic-to-hexagonal transformation. The effect of this strain on the transformation is discussed.
First-Ever Level 4 Multilateral Well in North Kuwait Successfully Completed, Improves Oil Production (2014)

Abstract Kuwait Oil Company (KOC) has recently drilled the first multilateral well in a North Kuwait field to improve oil production in productive layers subjected to water coning problems by increasing reservoir exposure using Level 4 multilateral technology. The multilateral well targeted the same sand in different directions with two laterals. Both of the laterals were drilled using rotary steerable drilling systems to reduce drilling time. The drilling process used a full suite of logging while drilling (LWD) tools, including azimuthal deep resistivity technologies, to ensure the well path is precisely geosteered within the reservoir boundaries and density/porosity tools in real-time, combined with specialized modeling software to position the well in the best possible reservoir. Level 4 multilateral technology was selected after performing an extensive geological assessment and studying the challenges of exploiting oil in the target sand reservoir. The 12 1/4-in. main section was cased and cemented with 9 5/8-in. casing to the landing point; the 8 1/2-in. lateral-I was drilled and completed with 5 1/2-in. inflow control devices (ICDs). The sidetrack was performed by cutting a window from a specialized latch coupling in the 9 5/8-in. casing; the 8 1/2-in. section was drilled to the landing point, and the 7-in. liner was run and fully cemented. The 6 1/8-in. lateral-II was drilled and completed with 4 1/2-in. ICDs. The fully cemented and cased junction or bifurcation should help achieve greater well integrity and prevent fluid migration from the adjacent area, while the specialized latch coupling should help ensure easy access to either of the laterals, as required. The ICD technology and swellable packers were selected to delay water breakthrough from an active aquifer. This publication describes the application of multilateral and geosteering technologies, and analyzes the advantages and disadvantages of the first multilateral well drilled in North Kuwait that began with a campaign of higher order (Level 4) multilateral. The well is considered to be a pilot well to identify the feasibility of using multilateral technology as a production model to help enhance oil recovery and reduce drilling costs in the field by replacing the cost of drilling new wells.
An hierarchical policy-based architecture for integrated management of grids and networks (2004)

The management of the underlying network infrastructure, which supports the grid communications, is not proceeded through the same management systems used for the grid management. In this scenario, an integrated management of grids and networks could turn the maintenance processes easier. This paper proposes an hierarchical policy-based architecture, whose goal is to allow such desired integration, where grid policies are translated to network policies following mapping rules defined by network administrators. It also describes a prototype implemented based on the architecture.
Fluids, both ionic and nonionic, over wide ranges of temperature and composition (1989)

Abstract
