Color Invariant Snakes (1998)

Snakes provide high-level information in the form of continuity constraints and minimum energy constraints related to the contour shape and image features. These image features are usually based on intensity edges. However, intensity edges may appear in the scene without a material/color transition to support it. As a consequence, when using intensity edges as image features, the image segmentation results obtained by snakes may be negatively affected by the imaging-process (e.g. shadows, shading and highlights). In this paper, we aim at using color invariant gradient information to guide the deformation process to obtain snake boundaries which correspond to material boundaries in images discounting the disturbing influences of surface orientation, illumination, shadows and highlights. Experiments conducted on various color images show that the proposed color invariant snake successfully find material contours discounting other ”accidental” edges types (e.g. shadows, shading and highlight transitions). Comparison with intensity-based snakes shows that the intensity-based snake is dramatically outperformed by the presented color invariant snake.
Integrated Spatio‐temporal Data Mining for Forest Fire Prediction (2008)

Abstract Forests play a critical role in sustaining the human environment. Most forest fires not only destroy the natural environment and ecological balance, but also seriously threaten the security of life and property. The early discovery and forecasting of forest fires are both urgent and necessary for forest fire control. This article explores the possible applications of Spatio‐temporal Data Mining for forest fire prevention. The research pays special attention to the spatio‐temporal forecasting of forest fire areas based upon historic observations. An integrated spatio‐temporal forecasting framework – ISTFF – is proposed: it uses a dynamic recurrent neural network for spatial forecasting. The principle and algorithm of ISTFF are presented, and are then illustrated by a case study of forest fire area prediction in Canada. Comparative analysis of ISTFF with other methods shows its high accuracy in short‐term prediction. The effect of spatial correlations on the prediction accuracy of spatial forecasting is also explored.
A New Fiber Optic Based Method for Delamination Detection in Composites (2003)

The early detection of closed delamination is important for ensuring the safety of laminated composite structures. In this article, an approach for delamination detection using fiber-optic interferometric technique is introduced. The integral strain along a fiber that is surface-attached to the composite is measured as a function of load position. By comparing the integral strain versus load position curve (or its first or second derivatives) for the undamaged and delaminated cases, the delamination location and size can be determined. To demonstrate the feasibility of the technique, numerical and experimental investigations have been carried out. The results of the study indicate that the proposed technique is applicable for delamination detection in both simply supported beams and beams on elastic foundation.
Immunotoxicity of aflatoxin M1: as a potent suppressor of innate and acquired immune systems in a subacute study (2018)

Overall, the data suggested that AFM<sub>1</sub> suppressed innate and acquired immunity. Therefore, with respect to consumer safety, it is extremely important to further control the level of AFM<sub>1</sub> in milk, and this should be considered as a precedence for risk management actions. © 2018 Society of Chemical Industry.
Dynamic characteristics of two 300 kW class dual keel space station concepts (1986)

Results from an investigation of the dynamic behavior of a 300 kW class solar dynamic powered, dual kell space station are presented. The purpose of the investigation was to determine and assess the influence of space station truss bay size on station controllability during rigid body attitude adjustment and orbit reboost maneuvers. The dual keel space station concept is defined and two finite element models (one which has a truss bay size of 5m and another with a truss bay size of 9 feet) are described. Rigid and flexible body characteristics of the two space station models are also presented. Finally, results from a transient response analysis, where the stations are subjected to an orbit reboost maneuver, are summarized.
HCV increases <i>Netrin-1</i> mRNA and protein. (2016)

Dauerhafter Beton - Grundlagen, Planung und Ausführung bei Frost- und Frosttaumittel-Beanspruchung. 6. Symposium Baustoffe und Bauwerkserhaltung Universität Karlsruhe (TH) ; Karlsruhe, 12. März 2009 (2009)

Betonbauteile unterliegen in unseren Breiten im Außenbereich grundsätzlich einer Frostbeanspruchung, häufig auch in Verbindung mit einer gleichzeitig gegebenen Taumittelbeanspruchung. Die aus diesen Beanspruchungen resultierenden Anforderungen werfen bei der Planung und Ausführung von entsprechenden Bauwerken häufig Fragen auf, beispielsweise zur korrekten Einteilung in die maßgebenden Expositionsklassen oder zur Wahl eines geeigneten Frost-Prüfverfahrens.\n\t\t\t\t\t\tIm vorliegenden Tagungsband zum 6. Symposium Baustoffe und Bauwerkserhaltung geben namhafte Autoren einen umfassenden Überblick über die Grundlagen, die Planung und die Ausführung von Betonbauwerken bei einer Frost- bzw. Frost-Taumittel-\n\t\t\t\t\t\tBeanspruchung.\n\t\t\t\t\t\tIm Themenblock Grundlagen werden zunächst die wetterbedingten Beanspruchungen und ihre klimatischen Ursachen erklärt. Weiterhin werden die im Beton wirkenden Schädigungsmechanismen erläutert sowie Wege und Möglichkeiten vorgestellt,\n\t\t\t\t\t\tdauerhafte Betonbauwerke bei Frost- bzw. Frost-Taumittel-Beanspruchung herzustellen. Die dabei eingesetzten Methoden sind in den aktuellen Betonbaunormen verankert, so dass eine hohe Dauerhaftigkeit in der Praxis sichergestellt ist. Im Zweifelsfall kann der Beton jedoch einer geeigneten Prüfung unterzogen werden.\n\t\t\t\t\tIm Themenblock Normung und Prüfung wird daher auch auf die Übertragbarkeit der verschiedenen Prüfmethoden auf die Praxis eingegangen. Der Themenblock Planung und Ausführung behandelt schließlich ausgewählte Bauwerke, bei denen ein starker Frostangriff beobachtet und gleichzeitig eine besonders hohe Lebensdauer gefordert wird.
Associations between Quantitative Mobility Measures Derived from Components of Conventional Mobility Testing and Parkinsonian Gait in Older Adults (2014)

Quantitative mobility subtask measures vary in their associations with parkinsonian gait scores and other parkinsonian signs in older adults. Quantifying the different facets of mobility has the potential to facilitate the clinical characterization and understanding the biologic basis for impaired mobility in older adults.
Growth, characterization and fabrication of thick detectors from as-grown Cd 0.9 Zn 0.1 Te:In by traveling heater method (2011)

CdZnTe, commonly known as CZT is the material of paramount importance for hard X-ray and gamma ray spectroscopy and imaging applications at room temperature. Over the years, the quality of CZT crystals and its charge transport properties has improved significantly making it an attractive detector material especially for homeland security applications. The applications for homeland security demand large and thick detectors to provide a sufficient stopping power for fast detection of high energy gamma photons. In this present report we have grown two inch diameter CZT by Traveling heater method (THM) technique. The as-grown crystals were characterized through photoluminescence (PL) mapping for composition uniformity, growth interface study, Te precipitations/inclusions studies. In order to evaluate our as-grown samples, charge transport characteristics have been studied for thick samples up to ~16mm thick. It has been demonstrated that by controlling the growth interface, visualization of large and thick (~16mm thick) detectors with fairly good response is possible from as-grown CZT detectors grown by THM technique.
Teaching Android Mobile Security (2019)

At present, computer science studies generally offer courses addressing mobile development and they use mobile technologies for illustrating theoretical concepts such as operating system, design patterns, and compilation because Android and iOS use a large variety of technologies for developing applications. Teaching courses on security is also becoming an important concern for academics, and the use of mobile platforms (such as Android) as supporting material is becoming a reasonable option. In this paper, we intend to bridge a gap in the literature by reversing this paradigm: Android is not only an opportunity to learn security concepts but requires strong pedagogical efforts for covering all the aspects of mobile security. Thus, we propose teaching Android mobile security through a two-dimensional approach. The first dimension addresses the cognitive process of the Bloom taxonomy, and the second dimension addresses the technical layers of the architecture of the Android operating system. We describe a set of comprehensive security laboratory courses covering various concepts, ranging from the application development perspective to a deep investigation of the Android Open Source Project and its interaction with the Linux kernel. We evaluated this approach, and our results verify that the designed security labs impart the required knowledge to the students.
Solid Solution Range and Microstructures of Melt‐Grown Mullite (1983)

The solid solution range of melt‐grown mullite was examined by crystal‐chemical methods. The maximum Al 2 O 3 content as determined by EDX was ∼83.6 wt%, 75 mol%, or the nominal composition 3Al 2 O 3 .SiO 2 . For samples of overall composition 81 to 83 wt% Al 2 O 3 , extra lines indicating crystallographic superstructure appeared in Guinier X‐ray patterns. The corresponding TEM microstructure consisted of a mullite matrix finely twinned on (001), the twins being 0.02 to 0.10 μm wide, with oriented exsolution of α‐A1 2 O 3 , often twinned, also being present. The analogy between mullite superstructure and that of plagioclase feldspars, as well as the relevance of these findings to the SiO 2 ‐Al 2 O 3 metastable phase equilibria are discussed.
Detecting and Responding to Threats in the Natural World (2018)

Organisms that evolved nervous systems that predict, detect, and assess ecological dangers are at a distinct survival advantage compared to those with less sophisticated neural machinery. The strategies generated and honed by adaptive survival circuits in humans, which we call the survival optimization system (SOS), are controlled by both conscious and implicit systems.
Efficacy of a Selective Binder of αVβ3 Integrin Linked to the Tyrosine Kinase Inhibitor Sunitinib in Ovarian Carcinoma Preclinical Models (2019)

Ovarian carcinoma, the most lethal gynecological cancer, is characterized by late diagnosis, with drug resistance limiting the efficacy of platinum-based therapy. Since some integrins are upregulated in cancer, including ovarian carcinoma, they represent a potential target for drug delivery. Receptor tyrosine kinases are also deregulated in cancer and their expression has been associated with drug resistance. Here, the antitumor effects of three conjugates possessing a selective binder of the extracellular portion of integrin α<sub>V</sub>β<sub>3</sub> covalently linked to the tyrosine kinase inhibitor sunitinib were investigated in cisplatin-sensitive and -resistant ovarian carcinoma cells expressing both tyrosine kinase VEGFR2 and α<sub>V</sub>β<sub>3</sub> at different levels. We found that one of the three compounds was active in inhibiting the growth of both drug-sensitive and -resistant cells in the micromolar range with a slightly increased potency in resistant cells as compared to sunitinib. The same compound markedly impaired cell migratory and invasive abilities and reduced paxillin phosphorylation. Antitumor activity studies in IGROV-1/Pt1 cells xenografted in nude mice revealed a striking activity of this conjugate versus sunitinib. Taken together, our results support the interest of integrin-targeted sunitinib conjugates for the treatment of drug-resistant tumors.
Acidity of HCl in Neutral Buffered Chloroaluminate Molten Salts (1996)

The Brønsted acidity of HCl in neutral buffered AlCl3:1-ethyl-3-methylimidazolium chloride (EMIC) melts has been compared to the Brønsted acidity of HCl in acidic (55 mol % AlCl3) melts. The acidities were compared using the spectrophotometric indicator method. Arenes were used as the weak indicator bases. The acidity of HCl in the neutral buffered melts was found to be dependent on both the type of buffering agent (LiCl, KCl, and NaCl) and on the concentration of the metal cation in the melt. An enhancement in Brønsted acidity of HCl is observed in the neutral buffered melts, although to a lesser degree than that in the acidic melts. A Hammett acidity function was determined for a NaCl (originally 55 mol % AlCl3) buffered melt and a LiCl (originally 55 mol % AlCl3) buffered melt. For a HCl (1 atm)/NaCl/AlCl3:EMIC (originally 55 mol % AlCl3) buffered melt, Ho = −11.3. Ho = −12.7 for a HCl (1 atm)/LiCl/AlCl3:EMIC (originally 55 mol % AlCl3) buffered melt.
An Implantable Sensor for Arterial Pressure Monitoring with Minimal Loading: Design and Finite Element Validation (2022)

This paper presents an in-vivo flexible pressure sensor that can be implanted around an artery for continuous measurement of blood pressure. Currently, in-vivo arterial sensor architectures rely on circular geometries fully encasing the artery perimeter, leading to significant reduction in blood pressure and flow rate inside the artery. The novelty of the sensor presented here lies in its geometrical structure and application that minimizes such disadvantages. The design consists of two arc-shaped flexible piezoelectric sensors located across each other and fixed together using medical-grade sutures on an artery periphery. Radial expansion of the artery during blood pulse wave is converted to an electrical signal through piezoelectric transduction. Finite element simulations were performed on laminar flow and solid mechanics domains to evaluate the effect of sensor presence on blood pressure and flow. Compared to previously reported sensor designs, it has been demonstrated that the pressure and flow values can be raised from 95% to 98% and from 66% to 88%, respectively. The improvement in flow rate is specifically important and vital for heart- and organ implantation-related medical operations.

PRODUCTS OF PHOTOSYNTHESIS IN CAULERPA SIMPLICIUSCULA (CHLOROPHYCEAE)1 (1975)

SUMMARY The kinetics of carbon flow through various metabolites of Caulerpa simpliciuscula C. Ag., a siphonaceous green alga, are described. The pattern of C fixation in this alga differs from those observed in higher plants and other green algae in a number of respects. After 40 min incubation, soluble β‐linked polyglucans are the most important labelled carbohydrates. Sucrose, although delectable, is never a major recipient of label and does not label until after other oligosaccharide fractions. The sugar monophosphates contain a large proportion of the 14 C assimilated even after 40 min and behave not only as metabolic intermediates, but also as storage pools. The pattern of ammo acid labelling resembles that reported for other species of green algae in that alanine becomes labelled most rapidly, followed by glycine, and much later by glutamate, glutamine and asparagine. These labelling patterns are discussed in the light, of what is known of patterns of C flow in other algae.

The Land Administration Domain Model (2015)

Societal drivers including poverty eradication, gender equality, indigenous recognition, adequate housing, sustainable agriculture, food security, climate change response, and good governance, influence contemporary land administration design. Equally, the opportunities provided by technological development also influence design approaches. The Land Administration Domain Model (LADM) attempts to align both: the data model provides a standardised global vocabulary for land administration. As an international standard it can stimulate the development of software applications and may accelerate the implementation of land administration systems that support sustainability objectives. The LADM covers basic information-related components of land administration including those over land, in water, below the surface, and above the ground. The standard is an abstract, conceptual model with three packages related to: parties (people and organisations); basic administrative units, rights, responsibilities, and restrictions (ownership rights); spatial units (parcels, and the legal space of buildings and utility networks) with a sub package for surveying, and representation (geometry and topology). This paper examines the motivation, requirements and goals for developing LADM. Further, the standard itself is described and potential future maintenance. Despite being a very young standard, ‘born’ on 1st December 2012, it is already possible to observe some of the impact of LADM: examples are provided.
ResBoost: characterizing and predicting catalytic residues in enzymes (2009)

ResBoost achieved 85% sensitivity for a 9.8% false positive rate and 73% sensitivity for a 5.7% false positive rate. ResBoost reduces the number of false positives by up to 56% compared to the use of evolutionary conservation scoring alone. We also illustrate the ability of ResBoost to identify recently validated catalytic residues not listed in the CSA.
