A Widely Tunable Compact Patch Antenna (2008)

In this letter, we propose a tunable patch antenna made of a slotted rectangular patch loaded by a number of posts close to the patch edge. The posts are short circuited to the ground plane via a set of PIN diode switches. Simulations and measurements verify the possibility of tuning the antenna in subbands from 620 to 1150 MHz. Good matching has been achieved over most of the bands. Other performed designs show that more than one octave can be achieved using the proposed structure.
Electroreflectance at a Semiconductor-Electrolyte Interface (1967)

The electroreflectance spectra of Si, Ge, $\ensuremath{\alpha}$-Sn, AlSb, GaP, GaAs, GaSb, InP, InAs, InSb, ZnO, ZnTe, CdS, CdSe, and CdTe are reported. The measurements were performed by the electrolyte technique in the 1-to 6-eV photon energy range. The data were processed by the Kramers-Kronig technique and the variation in ${\ensuremath{\epsilon}}_{1}$ and ${\ensuremath{\epsilon}}_{2}$ induced by the applied electric field obtained. Several sharp peaks were observed in all these spectra and interpreted in terms of critical points in the joint density of states for optical transitions. As a result, a large number of direct interband energy gaps and spin-orbit splittings is obtained. These spin-orbit splittings are interpreted and correlated by using the k. p method: Enough experimental information is available to determine the effects of spin-orbit interaction on the valence bands of most of these materials at any point in k space.
Lipid Peroxidation in Hyperlipidaemic Patients. A Study of Plasma using an HPLC-Based Thiobarbituric Acid Test (1993)

The question of "increased lipid peroxidation" in plasma from hyperlipidaemic patients was investigated using an improved HPLC-based assay for thiobarbituric acid-reactive material. Levels of TBARS in healthy human controls were at or close to zero, provided that butylated hydroxytoluene was added to the sample with the TBA reagents. Levels of plasma TBARS in hyperlipidaemic patients were elevated, although the absolute levels were much lower than those reported previously in the literature.
Effects of Bovine α-Lactalbumin on Gastric Defense Mechanisms in Naive Rats (2003)

We recently investigated the effects of the major proteins in cow's milk on gastric mucosal injuries in rat ulcer models. We found that alpha-lactalbumin (alpha-LA) has marked preventive effects against gastric mucosal injuries and that prostaglandin (PG) synthesis may contribute to these effects [Matsumoto et al., Biosci. Biotechnol. Biochem., 65, 1104-1111, 2001]. In this study, we investigated the effects of alpha-LA on several defense mechanisms of gastric mucosa by evaluating gastric PGE2 content, gastric mucin content, gastric luminal pH, gastric fluid volume, and gastric emptying in naive rats. Oral administration of alpha-LA (200, 500, and 1000 mg/kg) elevated endogenous PGE2 levels in gastric tissue and increased the gastric mucin contents of both the gastric fluid and the adherent mucus gel layer. In addition to these PG-related responses, alpha-LA also caused PG-independent responses such as elevation of gastric luminal pH, increase in gastric fluid volume, and delay in gastric emptying. These responses were observed to be dose-dependent (200-1000 mg/kg of alpha-LA). Thus, we demonstrated that alpha-LA enhances both PG-dependent and PG-independent gastric defense mechanisms in naive rats. Both of these mechanisms are probably involved in its gastroprotective action.
Desiccating stress-induced disruption of ocular surface immune tolerance drives dry eye disease (2015)

Dry eye is an allegedly autoimmune disorder for which the initiating mechanisms and the targeted antigens in the ocular surface are not known, yet there is extensive evidence that a localized T helper type 1 (Th1)/Th17 effector T cell response is responsible for its pathogenesis. In this work, we explore the reconciling hypothesis that desiccating stress, which is usually considered an exacerbating factor, could actually be sufficient to skew the ocular surface's mucosal response to any antigen and therefore drive the disease. Using a mouse model of dry eye, we found that desiccating stress causes a nuclear factor kappa B (NF-κB)- and time-dependent disruption of the ocular surface's immune tolerance to exogenous ovalbumin. This pathogenic event is mediated by increased Th1 and Th17 T cells and reduced regulatory T cells in the draining lymph nodes. Conversely, topical NF-κB inhibitors reduced corneal epithelial damage and interleukin (IL)-1β and IL-6 levels in the ocular surface of mice under desiccating stress. The observed effect was mediated by an augmented regulatory T cell response, a finding that highlights the role of mucosal tolerance disruption in dry eye pathogenesis. Remarkably, the NF-κB pathway is also involved in mucosal tolerance disruption in other ocular surface disorders. Together, these results suggest that targeting of mucosal NF-κB activation could have therapeutic potential in dry eye.
Comparison of Experimental and Analytical Tooth Bending Stress of Aerospace Spiral Bevel Gears (1999)

An experimental study to investigate the bending stress in aerospace-quality spiral bevel gears was performed. Tests were conducted in the NASA Lewis Spiral Bevel Gear Test Facility. Multiple teeth on the spiral bevel pinion were instrumented with strain gages and tests were conducted from static (slow roll) to 14400 RPM at power levels to 540kW (720 hp). Effects of changing speed and load on the bending stress were measured. Experimental results are compared to those found by three-dimensional finite element analysis.
Protein Synthesis in Vero Cells Abortively Infected with Influenza B Virus (1981)

Growth of influenza B virus was found to be greatly restricted in Vero cells compared with that in MDCK cells. The analysis of protein synthesis in infected cells showed that the synthesis of M protein is selectively inhibited in abortive infection. Cell fractionation experiments demonstrated that the viral glycoproteins, HA and NA, migrate from rough membranes via smooth membranes to plasma membranes in abortive as well as in productive cells. These results suggest that intracellular migration of influenza B virus glycoproteins occurs independently of the synthesis of M protein although M protein synthesis appears to be required for the formation of virus particles.
Measurement of Electrical Resistance after Nerve Injuries of the Hand (1980)

The authors measured electrical resistance of skin to define the sensory loss. A significant increase of the skin resistance was observed in the zone of sensory loss, as compared with the skin surfaces of normal innervation. The sensory map, sweating map (ninhydrine test) and the skin resistance map were also compared by the authors. The main advantages of the electrical skin resistance test are that it is a quantitative one, and takes less time than the other methods.
Combined optimisation of baseforms and model parameters in speech recognition based on acoustic subword units (2002)

A major challenge in speech recognition is creating a lexicon which is robust to inter and intra speaker variations. This is even more so in speech recognisers based on non linguistic units, e.g., acoustic subword units (ASWUs), since no standard pronunciation dictionaries are available. Thus the baseforms describing the vocabulary words in terms of the recognition units need to be generated from training data. We propose an algorithm for ASWU based speech recognition which performs a combined optimisation of the baseforms and the subword models. The resulting system has been tested on the DARPA Resource Management task, and is shown to perform comparably to a baseline phoneme based system.
Volume rendering compared with maximum intensity projection for magnetic resonance angiography measurements of the abdominal aorta (2004)

VRT is not suitable for diameter measurements of the abdominal aorta with fixed parameter settings but may be useful with user-selected settings.
On the coupling between stress and voltage in lithium-ion pouch cells (2014)

This paper studies the coupling between stress and open circuit voltage in a commercial lithium-ion pouch cell. This coupling is characterized through measurements of a coupling factor, which is defined as the rate of change in voltage with respect to applied mechanical stress. Based on a simple thermodynamic model, this coupling factor is expected to be related to the expansion characteristics of the pouch cell during charging. The expansion characteristics of the pouch cell are compared with measurements of the coupling factors at different states of charge, and are found to be in agreement with the simple thermodynamic model. This work opens the door for the development of mechanical force sensors based on intercalation materials.
Self-Tuning Planned Actions Time to Make Real-Time SOAP Real (2005)

This paper proposes a new method for programming and controlling distributed tasks. Applications declare behavior patterns that are used to automatically predict and reserve resources needed by applications in a heterogeneous distributed environment. The paper introduces a stochastic quality sampling driven scheduler and a rendezvous mechanism for matching pre-planned activities with actual payload data. The system is built around the first real-time SOAP implementation, also presented in this paper. It extends the XML Web services interoperability benefits that have proven themselves in e-business into two new areas: embedded and real-time. The paper presents an efficient implementation that runs on common microcontrollers and other computers.
Basic Description Logics (2007)

This chapter provides an introduction to Description Logics as a formal language for representing knowledge and reasoning about it. It first gives a short overview of the ideas underlying Description Logics. Then it introduces syntax and semantics, covering the basic constructors that are used in systems or have been introduced in the literature, and the way these constructors can be used to build knowledge bases. Finally, it defines the typical inference problems, shows how they are interrelated, and describes different approaches for effectively solving these problems. Some of the topics that are only briefly mentioned in this chapter will be treated in more detail in subsequent chapters.
<i>Bartonella (Rochalimaea) quintana</i>Endocarditis in Three Homeless Men (1995)

Functional code clone detection with syntax and semantics fusion learning (2020)

Clone detection of source code is among the most fundamental software engineering techniques. Despite intensive research in the past decade, existing techniques are still unsatisfactory in detecting "functional" code clones. In particular, existing techniques cannot efficiently extract syntax and semantics information from source code. In this paper, we propose a novel joint code representation that applies fusion embedding techniques to learn hidden syntactic and semantic features of source codes. Besides, we introduce a new granularity for functional code clone detection. Our approach regards the connected methods with caller-callee relationships as a functionality and the method without any caller-callee relationship with other methods represents a single functionality. Then we train a supervised deep learning model to detect functional code clones. We conduct evaluations on a large dataset of C++ programs and the experimental results show that fusion learning can significantly outperform the state-of-the-art techniques in detecting functional code clones.
Ontology driven multi-agent systems : an architecture for sensor web applications. (2009)

Advances in sensor technology and space science have resulted in the availability of vast quantities of high quality earth observation data.This data can be used for monitoring the earth and to enhance our understanding of natural processes.Sensor Web researchers are working on constructing a worldwide computing infrastructure that enables dynamic sharing and analysis of complex heterogeneous earth observation data sets.Key challenges that are currently being investigated include data integration; service discovery, reuse and composition; semantic interoperability; and system dynamism.Two emerging technologies that have shown promise in dealing with these challenges are ontologies and software agents.This research investigates how these technologies can be integrated into an Ontology Driven Multi-Agent System (ODMAS) for the Sensor Web.The research proposes an ODMAS framework and an implemented middleware platform, i.e. the Sensor Web Agent Platform (SWAP).SWAP deals with ontology construction, ontology use, and agent based design, implementation and deployment.It provides a semantic infrastructure, an abstract architecture, an internal agent architecture and a Multi-Agent System (MAS) middleware platform.Distinguishing features include: the incorporation of Bayesian Networks to represent and reason about uncertain knowledge; ontologies to describe system entities such as agent services, interaction protocols and agent workflows; and a flexible adapter based MAS platform that facilitates agent development, execution and deployment.SWAP aims to guide and ease the design, development and deployment of dynamic alerting and monitoring applications.The efficacy of SWAP is demonstrated by two satellite image processing applications, viz.wildfire detection and monitoring informal settlement.This approach can provide significant benefits to a wide range of Sensor Web users.These include: developers for deploying agents and agent based applications; end users for accessing, managing and visualising information provided by real time monitoring applications, and scientists who can use the Sensor Web as a scientific computing platform to facilitate knowledge sharing and discovery.An Ontology Driven Multi-Agent Sensor Web has the potential to forever change the way in which geospatial data and knowledge is accessed and used.This research describes this far reaching vision, identifies key challenges and provides a first step towards the vision.
Coherent use of opposing lenses for axial resolution increase II Power and limitation of nonlinear image restoration (2001)

We analyze the ability of nonlinear image restoration to remove interference artifacts in microscopes that enlarge the axial optical bandwidth through coherent counterpropagating waves. We calculate the images of an elaborate test object as produced by confocal, standing-wave, incoherent illumination interference image interference, and 4Pi confocal microscopes, and we subsequently investigate the extent to which the initial object can be restored by the information allowed by their optical transfer function. We find that nonlinear restoration is successful only if the transfer function is sufficiently contiguous and has amplitudes well above the noise level, as is mostly the case in a two-photon excitation 4Pi confocal microscope.
Isolation and partial characterization of sialoglycopeptides produced by a murine melanoma (1977)

<p>The objective of this paper is to examine and provide a holistic assessment of the “Space and Security” Policy in Europe, taking into consideration the European and national Space Strategies, Programmes and Governance. The importance of security in European Union (EU) activities is increasing after a decade of unprecedented crises and challenges of multidimensional nature. Space, as an enabling tool in support of multiple policy areas, can contribute to national and supranational security objectives. Space can contribute to and ultimately reinforce the European integration process. The first part of this paper focuses on the description of the security aspects of the space activities in Europe. The analysis includes the two main extents of space security – security from space and security in space. The second part focuses on the security aspects of the European Union (EU), European Space Agency (ESA) and National Space strategies, policies and programmes. The importance of coordination and cooperation between the stakeholders is emphasised. The final part considers how the European “Space and Security” strategies and policies contribute to European Space Integration.</p>
Sensitive detection of microRNA by chronocoulometry and rolling circle amplification on a gold electrode (2014)

We developed a quantitative detection scheme for nucleic acids, combining solid-phase rolling circle amplification and chronocoulometry (RCA-CC). A gold electrode was directly formed on a polystyrene substrate as a cost-effective and flexible biosensor for sensitive detection of microRNA (mir-143) in blood samples.
Root-associated bacteria promote grapevine growth: from the laboratory to the field (2016)

Background and Aims Laboratory and greenhouse experiments have shown that root-associated bacteria have beneficial effects on grapevine growth; however, these effects have not been tested in the field. Here, we aimed to demonstrate whether bacteria of different geographical origins derived from different crop plants can colonize grapevine to gain a beneficial outcome for the plant leading to promote growth at the field scale. Methods To link the ecological functions of bacteria to the promotion of plant growth, we sorted fifteen bacterial strains from a larger isolate collection to study in vitro Plant Growth Promoting (PGP) traits. We analysed the ability of these strains to colonise the root tissues of grapevine and Arabidopsis using greenfluorescent-protein-labelled strain derivatives and a cultivation independent approach. We assessed the ability of two subsets randomly chosen from the 15 selected strains to promote grapevine growth in two field-scale experiments in north and central Italy over two years. Parameters of plant vigour were measured during the vegetative season in de novo grafted vine cuttings and adult productive plants inoculated with the bacterial strains.
Effects of .GAMMA.-oryzanol on lipid metabolism in rats fed high-cholesterol diet. (1983)

The lipid contents of the plasma and liver and enzyme activities in the aorta were determined in rats given the following diets: Group I, normal diet (ND); Group II, high cholesterol diet (HCD, ND plus 1% cholesterol and 0.5% cholic acid); Group III, HCD plus 0.5% gamma-oryzanol; Group IV, HCD plus 2% gamma-oryzanol in the last days of the 4th, 8th and 12th week of the feeding period. Total cholesterol, low-density lipoprotein-cholesterol and very low-density lipoprotein-cholesterol in the plasma were significantly higher in rats in groups III and IV than in those in group II. High-density lipoprotein-cholesterol was increased in groups III and IV. There were no differences in the triglyceride or phospholipids concentrations in the plasma of rats in the four groups. The liver weight was higher in the HCD groups (groups II, III and IV) than in the ND group (group I). The cholesterol ester and triglyceride contents of the liver were higher in the HCD groups than in the ND group, and the increase was the least in group IV of the HCD groups. Changes in acid cholesterol esterase activity and acyl CoA: cholesterol acyltransferase activity in rat aorta homogenates to compensate for lipid deposition were greater in groups III and IV than in group II.
THE DEVELOPMENT OF AN INSULATED THERMIONIC CONVERTER-HEAT PIPE ASSEMBLY. (1965)

A contract objective was met during this report period when an A-1198C converter produced uniform electrical power output for a period of 506 hours when heated solely by a heat pipe. Progress was made in the improvement of the three converter module although problem areas still exist in high temperature ceramic to metal seal technology. Cesium quality was improved by the use of ultra high vacuum processing equipment. The effect of xenon and argon on converter performance was determined at emitter temperatures up to 1550 C. Tests continued on the insulating capabilities of aluminum oxide layers at 1600 C. Heat pipe processing was improved and simplified and prototype heat pipes were tested to 1600 C. Fabrication of additional A-1198C converters was continued. These converters will be used to obtain calibration test data with an electrical heater and for additional life tests. (Author)
Comparative investigation of detection of melamine in food powders (2009)

Recently, there have been numerous food scares particularly with the production of milk powders for infants. This has been caused by the addition of excess melamine to increase the tested protein count of a powder. In this paper we investigate the potential of THz-TDS for use in food quality control and compare this technique to other established techniques.
Photoelectric imaging in the 0.9-1.6 micron range (1981)

Carthage Cotton Valley Fracture Imaging Project - Imaging Methodology and Implications (1998)

Abstract SPE Paper 38577 introduced the Carthage Cotton Valley Hydraulic Fracture Imaging Project and described the initial imaging work. This paper describes the most recent methodology and implications of imaging hydraulic fractures utilizing microseisms recorded by extensive sensor arrays. Initial imaging work utilized a forward modeling approach. This paper will report further on confirmation of the event locations by inversion methods and by using decimation studies. A source parameter analysis will also be presented. Cotton Valley fracture treatments were performed at depths near 10,000 ft and imaged with arrays cemented in offset wells approximately 1300' away. Several techniques are utilized in both event location analysis and in analyzing certain characteristics of the events. These methodologies provide interpretations of the actual fractures and therefore have implications in the design and modeling of fractures. This paper will also point out and verify the need for development of an economical and commercial service to image fractures in real time. Decimation studies utilizing fewer optimally spaced receptors will determine the ability to develop a commercial service. Imaging of the hydraulic fractures at the Cotton Valley test site provides conclusions not easily accepted. Issues such as asymmetry, dimensions of the fracture and growth characteristics all prove to be substantially different than expected. Findings such as these will affect modeling techniques, design parameters, and eventually well spacing and development plans. Accurate mapping of a fracture will provide conclusive information that can be utilized to develop optimized and efficient fracture treatments. More effective fracture treatments will result in reduced well costs which allow field extension and expansion opportunities. Any operator or service company should apply lessons learned and presented in this paper. Imaging of the fracture and analysis of the actual failure mechanisms will provide a basis from which to design and model fractures in the Cotton Valley formation. Ideas for technology and completion strategies could be applicable to tight gas sand completions in other areas. This paper will show technical contributions such as:State of the art technologies utilized for mapping of the fractures.Analysis techniques that will be paramount in the future development of a commercial fracture mapping technology.Event parameter analysis yielding deductions concerning actual failure types in the rock. These analyses will have a major impact on fracture design and modeling. P. 599
