A Survey on Trust Management for Mobile Ad Hoc Networks (2010)

Managing trust in a distributed Mobile Ad Hoc Network (MANET) is challenging when collaboration or cooperation is critical to achieving mission and system goals such as reliability, availability, scalability, and reconfigurability. In defining and managing trust in a military MANET, we must consider the interactions between the composite cognitive, social, information and communication networks, and take into account the severe resource constraints (e.g., computing power, energy, bandwidth, time), and dynamics (e.g., topology changes, node mobility, node failure, propagation channel conditions). We seek to combine the notions of "social trust" derived from social networks with "quality-of-service (QoS) trust" derived from information and communication networks to obtain a composite trust metric. We discuss the concepts and properties of trust and derive some unique characteristics of trust in MANETs, drawing upon social notions of trust. We provide a survey of trust management schemes developed for MANETs and discuss generally accepted classifications, potential attacks, performance metrics, and trust metrics in MANETs. Finally, we discuss future research areas on trust management in MANETs based on the concept of social and cognitive networks.

Unexpected Isolation of 4‐Isothiocyanatomethylene‐4H‐pyridine‐1‐carboxylic Acid Ethyl Ester as Potential Template in Organic Synthesis (2005)

Abstract The synthesis of 4‐isothiocyanatomethyl‐pyridine 4 in 36% yield by Hasegawa and Kotani (Japanese patent 49088878, 1974) has spurred us to investigate this preparation in detail. In addition to this compound, 4‐isothiocyanatomethylene‐4H‐pyridine‐1‐carboxylic acid ethyl ester 3 can be isolated. The synthesis of both compounds 3 and 4 were optimized to 75% and 50% yield respectively. Reaction of compound 3 with methylamine gave thiourea derivatives 5, the same product obtained on reacting 4‐isothiocyanatomethyl‐pyridine 4 with methylamine. We succeed in adjusting the reaction conditions to obtain high yield either from compound 3 or isothiocyanate derivatives 4. Keywords: 4‐Isothiocyanatomethyl‐pyridinethiourea derivativesisothiocyanate derivatives
Effect of Graft-Host Interference Fit on Graft Integration after Osteochondral Allograft Transplantation: A Comparative MRI Analysis of Two Instrumentation Sets (2019)

OCAs show excellent osseous integration at the graft-host junction at 12 months postoperatively. The comparative MRI analysis of two instrumentation sets yielded no significant differences in terms of graft integration, bone marrow edema, or cystic formation. Hence, this study cannot recommend one instrumentation set over the other. Consequently, the individual preference should guide the surgeon's selection of instrumentation for OCA transplantation.
Nanoencapsulated Dietary Polyphenols for Cancer Prevention and Treatment: Successes and Challenges (2020)

Many dietary polyphenols have been investigated for their therapeutic potential either as single agents or in combinations. Despite the significant anticancer potential of these polyphenols in <i>in vitro</i> cell culture and <i>in vivo</i> animal models, their clinical applications have been limited because of challenges such as ineffective systemic delivery, stability and low bioavailability. Nanoencapsulation of these polyphenols could prolong circulation, improve localization, enhance efficacy and reduce the chances of multidrug resistance. This review summarized the use of various polyphenols especially epigallocatechin gallate, quercetin, curcumin and resveratrol as nanoformulations for cancer prevention and treatment. Despite some success, more research is warranted to design a nanoencapsulated combination of polyphenols, effective in <i>in vitro</i>, <i>in vivo</i> and human systems.
Size selection of oxidized GaN crystallites and their cathodoluminescence properties (2004)

GaN particles of different sizes were separated by a sedimentation technique. We find that a correlation exists between the cathodoluminescence (CL) spectra of the particles and their average sizes. These results imply that the particles contain a substantial fraction of GaN nanocrystallites (NCs) whose emission is shifted by quantum size effects and whose proportions differ with the overall size of the particle. X-ray photoelectron spectroscopy data combined with ion etching show that the NCs comprising these clusters have a GaN core surrounded by a gallium oxide shell. The results indicate that size-separated GaN particles may be useful CL sources of light for exciting phosphors over a range of UV wavelengths without the need for alloys such as AlGaInN.
Gauge Transformations for Recasting Potential Representations (2019)

Conversion of a field representation such as TM <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">z</sub> to a different representation such as a TM <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> by means of general gauge transformations is demonstrated by considering radiation from a dipole.
Sensor System for Open/Closed Eye Detection in Infants During Feeding (2019)

Rapid weight gain during infancy expands the threat of obesity. Currently, there is a lack of tools to monitor the feeding behavior of infants. This paper presents a sensor system and a method for inspecting satiety cues exhibited by infants during feeding in the form of opening/closing of the eyes. Open eyes and vigorous sucking indicate an alert, actively feeding infant, while eye closing in combination with a slower frequency or lower strength of sucking indicate that an infant is getting full and falling asleep. The monitoring is performed by a sensor system consisting of a feeding bottle instrumented with a camera to monitor facial expression and a pressure sensor to monitor sucking. A method for open eye detection is proposed based on the histograms of oriented gradients features and multi-stage cascade classifier. In a pilot study of 4 infants, a recall value of 82.40% and F1-score of 80.79% was achieved while testing on 914 infant images.
Mapping and Ablation of Idiopathic Ventricular Fibrillation (2002)

Primary idiopathic ventricular fibrillation is a syndrome characterized by dominant triggers from the distal Purkinje system. These sources can be eliminated by focal energy delivery.
Study on Hydrogen-Induced Cracking in the Heat-Affected Zone of Heavy Forgings Overlaid by Stainless Steel (1981)

Contrary to general knowledge, it was found that cold cracks in the heat-affected zone (HAZ) under stainless steel weld overlay on the tubesheet forging of a steam generator were generated during fabrication and not in service.The cold cracking, known as “hydrogen-induced cracking,” occurs when four factors are simultaneously satisfied: existence of hydrogen in the HAZexistence of tensile stress or strainexistence of microstructure susceptible to hydrogen embrittlementlow temperature (<150°C).The conditions are still satisfied at welding of the second layer without pre-heating, even after pre-heat is applied for welding of the first layer, followed by soaking treatment. To avoid cold cracking, it is recommended that pre-heating should be maintained at least during welding of the first and second layers and until post-weld heat treatment or soaking treatment.
Transform Learning Assisted Graph Signal Processing for Low Rate Electrical Load Disaggregation (2020)

Separating the individual sources with less differentiating features and random time overlaps in a superposition is a challenging problem that arises in many scenarios. Disaggregating low sampled smart meter data is one such important and interesting use case. In this paper, a novel joint optimization formulation using Transform Learning (TL) assisted with Graph Signal Processing (GSP) is presented to reconstruct the individual operational waveforms of the electrical loads. Data-driven transforms are utilized to learn the individual load characteristics. Treating the transform coefficients as load activations, graph signal smoothness is exploited to estimate the coefficients in the test phase using the coefficients learnt during the training phase. The requisite optimization formulation and the derivation of the necessary update steps are presented. The efficacy of the proposal is demonstrated by the load identification and consumption estimation results obtained for residential load disaggregation, considering both real and simulated data along with comparisons against some of the recent works in this domain.
Visualizing vector field topology in fluid flows (1991)

Methods for automating the analysis and display of vector field topology in general, and flow topology in particular, are described. By using techniques to extract and visualize topological information, it is possible to combine the simplicity of schematic depictions with the quantitative accuracy of curves and surfaces computed directly from the data. Two-dimensional vector field topology is discussed, covering critical points and time-dependent flows, to provide a basis for the examination of topology in three-dimensional separated flows. Surface topology and separation structures in three-dimensional flows are then addressed. The construction of representations of tangent surfaces that are accurate, as well as efficient to compute and display, is examined, covering tessellation, clipping, and refinement. Locating, characterizing, and displaying three-dimensional critical points are considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
A humanIL10BAC transgene reveals tissue-specific control of IL-10 expression and alters disease outcome (2009)

Interleukin (IL)-10 is an immunoregulatory cytokine that is produced by diverse cell populations. Studies in mice suggest that the cellular source of IL-10 is a key determinant in various disease pathologies, yet little is known regarding the control of tissue-specific human IL-10 expression. To assess cell type-specific human IL-10 regulation, we created a human IL-10 transgenic mouse with a bacterial artificial chromosome (hIL10BAC) in which the IL10 gene is positioned centrally. Since human IL-10 is biologically active in the mouse, we could examine the in vivo capacity of tissue-specific human IL-10 expression to recapitulate IL-10-dependent phenotypes by reconstituting Il10(-/-) mice (Il10(-/-)/hIL10BAC). In response to LPS, Il10(-/-)/hIL10BAC mice proficiently regulate IL-10-target genes and normalize sensitivity to LPS toxicity via faithful human IL-10 expression from macrophages and dendritic cells. However, in the Leishmania donovani model of pathogen persistence, Il10(-/-)/hIL10BAC mice did not develop the characteristic IL-10(+)IFN-gamma(+)CD4 T cell subset thought to mediate persistence and, like Il10(-/-) mice, cleared the parasites. Furthermore, the IL-10-promoting cytokine IL-27 failed to regulate transgenic human IL-10 production in CD4(+) T cells in vitro which together suggests that the hIL10BAC encodes for weak T cell-specific IL-10 expression. Thus, the hIL10BAC mouse is a model of human gene structure and function revealing tissue-specific regulatory requirements for IL-10 expression which impacts disease outcomes.
Characterization of the endomannosidase pathway for the processing of N-linked oligosaccharides in glucosidase II-deficient and parent mouse lymphoma cells. (1992)

Studies on N-linked oligosaccharide processing in the mouse lymphoma glucosidase II-deficient mutant cell line (PHAR2.7) as well as the parent BW5147 cells indicated that the former maintain their capacity to synthesize complex carbohydrate units through the use of the deglucosylation mechanism provided by endomannosidase. The in vivo activity of this enzyme was evident in the mutant cells from their production of substantial amounts of glucosylated mannose saccharides, predominantly Glc2Man; moreover, in the presence of 1-deoxymannojirimycin or kifunensine to prevent processing by mannosidase I, N-linked Man8GlcNAc2 was observed entirely in the form of the characteristic isomer in which the terminal mannose of the alpha 1,3-linked branch is missing (isomer A). In contrast, parent lymphoma cells, as well as HepG2 cells in the presence of 1-deoxymannojirimycin accumulated Man9GlcNAc2 as the primary deglucosylated N-linked oligosaccharide and contained only about 16% of their Man8GlcNAc2 as isomer A. In the presence of the glucosidase inhibitor castanospermine the mutant released Glc3Man instead of Glc2Man, and the parent cells converted their deglucosylation machinery to the endomannosidase route. Despite the mutant's capacity to accommodate a large traffic through this pathway no increase in the in vitro determined endomannosidase activity was evident. The exclusive utilization of endomannosidase by the mutant for the deglucosylation of its predominant N-linked Glc2Man9GlcNAc2 permitted an exploration of the in vivo site of this enzyme's action. Pulse-chase studies utilizing sucrose-D2O density gradient centrifugation indicated that the Glc2Man9GlcNAc2 to Man8GlcNAc2 conversion is a relatively late event that is temporally separated from the endoplasmic reticulum-situated processing of Glc3Man9GlcNAc2 to Glc2Man9GlcNAc2 and in contrast to the latter takes place in the Golgi compartment.
A newly emerging toxic dinoflagellate, Pfiesteria piscicida: natural ecology and toxicosis to fish and other species. (2000)

Pfiesteria, a toxic dinoflagellate, recently has emerged as a cause of fish kills near the East Coast. Recent research into one species. Pfiesteria piscicida, has revealed a complex life cycle of at least 24 stages. Metamorphosis of one stage to another often depends on presence or absence of fish. Growth of P piscicida is promoted both directly and indirectly by nutrients such as inorganic phosphate and nitrate, as well as organic phosphate, and may be related to effluent-induced blooms. Sewage and agricultural runoff flowing into estuaries often provide these nutrients and may be correlated with the majority of fish kills in the Atlantic coastal region of the US (5). P piscicida is extremely toxic, with a low density capable of killing fish within 3 minutes (1,3,12). Fish exposed to sublethal doses of the toxin have prominent lesions. The syndrome leads to population level death losses and associated economic losses in local fisheries.
Gas purification by the plasma-oxidation of a rotating sacrificial electrode (2015)

A novel approach for the purification of inert gases by means of a dielectric barrier discharge (DBD) plasma has been demonstrated for argon and nitrogen. A rotating sacrificial electrode has been employed together with an electrode cleaning system to remove passivating product films during the plasma processing and thus enhance capacity and reaction rates. The purification of nitrogen using this approach was shown to be quite successful. The conditioning of technical argon yielded rotational temperatures well beyond 150 °C, thus being unable to remove the water content effectively.
Synthesis and characterization of copper complexes of phenylpiperazine ring-based ligands and evaluation of their antimicrobial, BSA binding, computational, and molecular docking studies (2022)

Abstract This paper describes the synthesise of copper complexes of phenylpiperazine ring-based ligands and characterization via physical and spectroscopic methods. Structure of complexes has been proposed on the basis of UV-vis, IR and Mass fragmentation pattern and additionally supported by electrochemical and thermogravimetric analysis. Low molar conductance value of metal complexes in water and DMSO suggest non-ionic nature of complexes which is in agreement of proposed structure. TGA curve, where loss of coordinated solvent molecules starts early followed by loss of ligand itself also support the proposed structures. Percentage ash content analysis also indicate that only one copper metal is binding to the ligands reported here. Antibacterial activity of metal complexes has been performed by agar well diffusion method and indicated these metal complexes possess higher activity than the corresponding ligands. Binding interaction of these complexes were studied with BSA protein by UV-vis spectroscopic methods and binding constant was calculated which indicated that the complexes are having moderate affinity. Some complexes were also geometrically optimized to lowest energy ground state by using DFT calculations. Docking study of these optimized structures with BSA protein revealed these metal complexes exhibit hydrophobic interaction owing to the aromatic bulk in the ligand.

Class Is Not Dead—It Has Been Buried Alive: Class Voting and Cultural Voting in Postwar Western Societies (1956–1990) (2007)

By means of a reanalysis of the most relevant data source—the International Social Mobility and Politics File—this article criticizes the newly grown consensus in political sociology that class voting has declined since World War II. An increase in crosscutting cultural voting, rooted in educational differences rather than a decline in class voting, proves responsible for the decline of traditional class-party alignments. Moreover, income differences have not become less but more consequential for voting behavior during this period. It is concluded that the new consensus has been built on quicksand. Class is not dead—it has been buried alive under the increasing weight of cultural voting, systematically misinterpreted as a decline in class voting because of the widespread application of the so-called Alford index.
Plastic optical fibre sensor for Madeira wine monitoring (2014)

Madeira wine is a fortified wine produced in Madeira Island, Portugal. Its characteristics are strongly influenced by the winemaking method used which includes a typical and unique step called estufagem. This process consists on heating the wine up to 55 ºC for at least 3 months. In this paper, the characterization of the sensor for the pilot scale facility of estufagem installed in Madeira University is presented, being the device an optimization of a previous version. The response of the sensor was tested towards colour and refractive index, showing a good performance. Madeira wine with different estufagem times was also analysed.
Tenth micron p-MOSFET's with ultra-thin epitaxial channel layer grown by ultra-high-vacuum CVD (2002)

We have, for the first time, demonstrated silicon MOSFET's with an ultra-thin epitaxial channel grown by low-temperature UHV-CVD; this allows the channel region to be doped with high precision. The boron concentration and epitaxial layer thickness can be chosen independently, so it is easily possible to adjust the threshold voltage of the p-MOSFET's even in the case of n-type polysilicon gates. It was confirmed that choosing an ultra-thin epitaxial layer-in the 10 nm range-leads to suppression of the short-channel effects in n-type polysilicon gate buried-channel MOSFET's, while maintaining an appropriate value of threshold voltage.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Determination of nanomolar levels of formate in natural waters based on a luminescence enzymatic assay (1990)

A light-producing reaction utilizing three enzymes, bacterial luciferase, dehydrogenase and diaphorase, can be used to determine formic acid in natural waters at nanomolar concentrations. The method is rapid and convenient, requiring no preconcentration, desalting or derivatization procedures. Determinations can be done on small sample volumes (25 μl) at room temperature and pH 7. The precision (relative standard deviation for sea water samples containing 1.0 μM formate was 9.0% (n = 15). The reaction is specific for formate with a detection limit of 20 nM (signal-to-noise ratio = 3). Results for applications of the method to sea, estuarine and rain water are given.

Pentosan inhibits angiogenesis in vitro and suppresses prostate tumor growth in vivo. (1994)

Pentosan polysulfate (PPS) is a highly negatively charged polysaccharide which has activity against multiple tumor types in the preclinical setting. We demonstrate here that Pentosan inhibits the growth of the anaplastic Dunning R3327 rat prostate adenocarcinoma MAT-LyLu when treatment was started when the tumor was not palpable but has little effect against established tumors. This inhibition may be mediated by the effect of Pentosan on endothelial cells. Pentosan, in combination with hydrocortisone, inhibits endothelial cell motility and tubule formation in vitro and inhibits capillary formation in the chicken chorioallantoic membrane (CAM) assay. These data suggest that Pentosan may be a potent inhibitor of tumor-associated angiogenesis and may be an effective agent for the prevention and/or suppression of prostate cancer growth.
An Early Warning System for Suspicious Accounts (2017)

In the face of large-scale automated cyber-attacks to large online services, fast detection and remediation of compromised accounts are crucial to limit the spread of new attacks and to mitigate the overall damage to users, companies, and the public at large. We advocate a fully automated approach based on machine learning to enable large-scale online service providers to quickly identify potentially compromised accounts. We develop an early warning system for the detection of suspicious account activity with the goal of quick identification and remediation of compromised accounts. We demonstrate the feasibility and applicability of our proposed system in a four month experiment at a large-scale online service provider using real-world production data encompassing hundreds of millions of users. We show that - even using only login data, features with low computational cost, and a basic model selection approach - around one out of five accounts later flagged as suspicious are correctly predicted a month in advance based on one week's worth of their login activity.
S/390 CMOS Cryptographic Coprocessor Architecture: Overview and design considerations (1999)

This paper describes the design objectives and presents an overview of the design for the IBM S/390® CMOS Cryptographic Coprocessor, also known as the S/390 cryptographic module (SCM). The SCM is fully compatible with the earlier S/390 cryptographic module, ICRF (Integrated Cryptographic Facility), and has been certified by the National Institute of Standards and Technology at the highest level of security qualification. The principal features and unique characteristics of the SCM are summarized in the context of the architecture design.
