Algorithm analysis and mapping environment for adaptive computing systems: further results (2003)

We are developing an integrated algorithm analysis and mapping environment particularly tailored for signal processing applications on Adaptive Computing Systems (ACS). Our environment allows a designer to map signal processing algorithms to an ACS faster, by an order of magnitude, than is currently possible.
The effect of finite resource on environmental policy (2000)

Abstract Since pollution abatement activities require the consumption of resource, they can be seen as an exchange of resource for clean environment. In perspective of finite resource supply and sustainable development, a model is presented to analyze the effect of various exogenous parameters such as the resource stock level, technical progress, and market demand, etc. on the optimal point. The results reveal that (1) the society with less resource stock must take some other measures such as technology innovation to increase its production level and improve its environment, (2) the increase in production is limited by technological progress, and (3) the increase in market demand leads to the increase in production, but also make environmental quality worse.
Role of Nuclear Factor‐Kappa B (NF‐κB) in Inflammation, Periodontitis, and Atherogenesis (2001)

Atherosclerosis, the major cause of death and disability in the United States, is a chronic disease with inflammatory components. The first objective of this review is to explain how activation of NF-kappa B contributes to atherosclerosis. The second objective is to describe a potential link between inflammation, activation of NF-kappa B, and periodontitis. The nuclear transcription factor NF-kappa B controls the expression of many genes linked to atherogenesis including those involved with inflammation. We hypothesize that one unifying mechanism in this complex disease is the activation of NF-kappa B. The mechanism(s) that activates NF-kappa B in atherogenesis is unknown and the effect of inhibiting NF-kappa B activation on atherogenesis is untested. Periodontal disease has now been established as a risk factor for atherosclerosis and its thrombotic complications. It is unknown if periodontal disease contributes to the initiation or progression of atherosclerosis. We hypothesize that the chronic and intense inflammatory response accompanying periodontal disease produces an excess burden of circulating mediators of inflammation that initiate or exacerbate the inflammatory components of atherogenesis. Further understanding of the mechanisms involved in the activation of NF-kappa B in atherosclerosis could lead to important therapeutic applications especially as it relates to the impact of periodontitis.
Controlled death (apoptosis) of normal and putative preneoplastic cells in rat liver following withdrawal of tumor promoters (1984)

Numerous drugs, hormones and environmental pollutants induce liver growth by hypertrophy and/or hyperplasia, and promote preferential growth of putative preneoplastic foci in the liver. In the present study the regression of hyperplasia after cessation of inducer/promoter treatment was studied in normal liver and in liver foci. High doses of cyproterone acetate (CPA), a synthetic sex steroid, were administered to rats and produced a doubling of liver size; after cessation of treatment liver size declined, and 27% of the total liver DNA disappeared within 6 days. In histological sections from the involuting liver no necroses, but numerous apoptotic bodies (ABs) were found; retreatment with CPA interrupted the formation of ABs. These findings suggest that elimination of excess liver DNA after cessation of CPA treatment is due to controlled cell death by apoptosis. In a further series of experiments putative preneoplastic foci were produced by a single dose of N-nitrosomorpholine and subsequently stimulated to grow by 10 or 28 weeks of phenobarbital (PB) treatment. After withdrawal of PB numerous ABs were present in normal liver and in the foci; in both, retreatment with PB decreased the appearance of ABs. It appears that inhibition of cell death by PB may contribute to tumour promotion. Under all conditions tested more ABs were found in the foci than in non-focal parts of the liver, suggesting an enhanced cell turnover in foci. The apparent sensitivity of foci to mechanisms controlling cell death might eventually provide a means for elimination of preneoplastic lesions.

Isolation, Identification, and Structure of a Potent Alkyl-Peroxyl Radical Scavenger in Crude Canola Oil, Canolol (2005)

Alkylhydroperoxides in oxidized oil are undesirable components because they become alkylperoxyl radicals (ROO*) in the presence of heme, hemoglobin, or myoglobin in red meat. ROO* are biochemically reactive and damage nucleic acids and proteins, thereby harming living cells. We isolated a component, a highly potent ROO* scavenger, from crude canola oil (rapeseed), which we designated canolol, and identified its chemical structure, 4-vinyl-2,6-dimethoxyphenol. The canolol content of crude canola oil greatly increased after the seed was roasted as compared with that from unroasted seed, but it decreased in highly purified oil. This anti-ROO* activity was highest in crude oil, deceased after each refining step, and was lowest in highly purified refined oil. Canolol was thus generated during roasting. As shown previously, canolol is one of the most potent anti-ROO* components in crude canola oil and its potency is much greater than that of well-known antioxidants, including alpha-tocopherol, vitamin C, beta-carotene, rutin, and quercetin.
Robustness to Out-of-Distribution Inputs via Task-Aware Generative Uncertainty (2019)

Deep learning provides a powerful tool for robotic perception in the open world. However, real-world robotic systems, especially mobile robots, must be able to react intelligently and safely even in unexpected circumstances. This requires a system that knows what it knows, and can estimate its own uncertainty for unfamiliar, out-of-distribution observations. Approximate Bayesian approaches are commonly used to estimate uncertainty for neural network predictions, but struggle with out-of-distribution observations. Generative models can in principle detect out-of-distribution observations as those with a low estimated density, but overly pessimistic as an uncertainty measure, since the mere presence of an out-of-distribution input does not by itself indicate an unsafe situation. Intuitively, we would like a perception system that can detect when task-salient parts of the image are unfamiliar or uncertain, while ignoring task-irrelevant features. In this paper, we present a method for uncertainty-aware robotic perception that combines generative modeling and model uncertainty. Our method estimates an uncertainty measure about the model's prediction, taking into account an explicit generative model of the observation distribution to handle out-of-distribution inputs. We evaluate our method on an action-conditioned collision prediction task with both simulated and real data, and demonstrate that our approach improves on a variety of Bayesian neural network techniques.

Persistent B19 Parvovirus Infection in Patients Infected with Human Immunodeficiency Virus Type 1 (HIV-1): A Treatable Cause of Anemia in AIDS (1990)

The B19 parvovirus is a remediable cause of severe chronic anemia in HIV-infected patients. Recognition of and therapy for parvovirus in this population will avoid erythrocyte transfusion and should prevent transmission of the virus to other persons, including immunosuppressed persons and women of child-bearing age.
Steroid-Bridged Anthryloligothienylporphyrins:  Synthesis and Study on the Intramolecular Energy Transfer (1998)

The novel steroid-bridged energy transfer system 2 was prepared starting from epi-androsterone. The linkage of both the anthrylthienyl and the bithienyl group in the 3- and 17-position of the steroid was achieved by Grignard reaction of the respective carbonyl function of the steroid component. The synthesis was accomplished by linkage of the porphyrin group according to Lindsey's method. This synthetic strategy also enables the approach to molecular subunits required as reference compounds. The photophysical properties were studied using time-resolved fluorescence and fluorescence excitation spectroscopy. Reference donor molecule 6 exhibitsin analogy to other anthryloligothiophenes studieda dual fluorescence: a blue anthracene-like fluorescence and a dynamically coupled delayed red fluorescence resulting from the relaxed excited state. On the basis of these results, supermolecule 2 was investigated. Besides the typical porphyrin emission, a high energetic fluorescence (blue fluorescence) was detected in 2 which results unambiguously, as stated from spectra of 6, from the donor part of 2. The lifetime of this fluorescence is shortened compared with that of 6. Supermolecule 2 is the first in the series of our energy transfer systems exhibiting donor fluorescence despite a very efficient intramolecular energy transfer (at least 99%).
Proteins in cerebrospinal fluid and plasma of fetal sheep during development (1980)

1. The concentration of total protein in c.s.f. and plasma has been measured in fetal sheep of different gestational ages and in the adult. In c.s.f. it was highest (approximately 840 mg/100 ml.) in the youngest fetuses (35 days) and declined steeply by 60 days (260 mg/100 ml.). It decreased less markedly in the last half of gestation to reach about 50 mg/100 ml. at 125 days which is twice the adult value. Protein concentration in plasma was lowest in the youngest fetuses and did not rise much until the second half of gestation during which time it doubled. There was a further rather larger increase between the late fetal (125 days) stage and the adult. 2. Albumin, fetuin, α-fetoprotein (AFP), transferrin and lipoprotein were identified in c.s.f. and plasma. 3. The concentrations of albumin, AFP and fetuin in c.s.f. and plasma at different gestational ages were measured using immunodiffusion and radioimmuno-assays. 4. Albumin was the major protein in plasma at all ages studied (35-128 days gestation and adult). Its concentration increased throughout gestation whereas that of fetuin was similar at all fetal ages and that of AFP declined markedly during the second half of gestation. In the adult, fetuin was only about 0·1% of the total protein in plasma and AFP was not detectable. 5. In 35-40 day fetuses albumin, AFP and fetuin accounted for 90% of the total protein concentration in plasma and for about 70-80% of the total protein concentration of c.s.f. As gestation progressed the concentration of all three proteins in c.s.f. declined. But the concentration of AFP and fetuin fell more rapidly and to a greater extent than that of albumin; neither AFP nor fetuin could be detected in adult c.s.f. 6. The c.s.f.: Plasma ratio was above 50% for AFP and above 60% for fetuin at 35 days compared with about 25% for albumin at the same fetal age. The c.s.f.: plasma ratios for all three proteins declined with increasing fetal age and were not significantly different from each other by about mid gestation.
Integration techniques for VXIbus instrumentation systems (2002)

The author discusses a common approach to hardware and software development as well as integration techniques developed as a result of using VXI in its test systems. The VXIbus allows the system integrator to purchase commercial cards and integrate them with unit under test (UUT)-specific cards in one or more chassis. VXI provides a standard backplane and communication protocol to allow these cards to interface with each other. The effort to integrate these cards depends upon the type of card being used and the level of customization that is required by the application. By developing standard hardware and firmware interfaces, the design and integration of UUT-specific cards can be made less complex. The chassis and system level integration effort can be eased by the use of commercial software and hardware packages designed for this purpose.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Light-harvesting chlorophyll a/b-binding proteins, positively involved in abscisic acid signalling, require a transcription repressor, WRKY40, to balance their function (2013)

The light-harvesting chlorophyll a/b-binding (LHCB) proteins are the apoproteins of the light-harvesting complex of photosystem II. In the present study, we observed that downregulation of any of the six LHCB genes resulted in abscisic acid (ABA)-insensitive phenotypes in seed germination and post-germination growth, demonstrating that LHCB proteins are positively involved in these developmental processes in response to ABA. ABA was required for full expression of different LHCB members and physiologically high levels of ABA enhanced LHCB expression. The LHCB members were shown to be targets of an ABA-responsive WRKY-domain transcription factor, WRKY40, which represses LHCB expression to balance the positive function of the LHCBs in ABA signalling. These findings revealed that ABA is an inducer that fine-tunes LHCB expression at least partly through repressing the WRKY40 transcription repressor in stressful conditions in co-operation with light, which allows plants to adapt to environmental challenges.
Fault diagnosis and isolation in aircraft gas turbine engines (2008)

This paper formulates and validates a novel methodology for diagnosis and isolation of incipient faults in aircraft gas turbine engines. In addition to abrupt large faults, the proposed method is capable of detecting and isolating slowly evolving anomalies (i.e., deviations from the nominal behavior), based on analysis of time series data observed from the instrumentation in engine components. The fault diagnosis and isolation (FDT) algorithm is based upon Symbolic Dynamic Filtering (SDF) that has been recently reported in literature and relies on the principles of Symbolic Dynamics, Statistical Pattern Recognition and Information Theory. Validation of the concept is presented and a real life software architecture is proposed based on the simulation model of a generic two-spool turbofan engine for diagnosis and isolation of incipient faults.
Designing Multiplayer Online Games Using the Real-Time Framework (2012)

This chapter describes a novel, high-level approach to designing and executing online computer games. The approach is based on our Real-Time Framework (RTF) and suits a wide spectrum of online games including Massively Multiplayer Online Games (MMOG) and First-Person Shooters (FPS). The authors address major design issues like data structures and Area of Interest (AoI), with a special focus on the scalability of games implemented on multiple servers, including distribution of the game state, inter-server communication, object serialization and migration, etc. The chapter illustrates the approach with two case studies: the design of a new multi-player online game and bringing the single-server commercial game Quake 3 to multiple servers in order to increase the number of simultaneous players. The authors show the place of their approach in the taxonomy of game development approaches, and they report experimental results on the performance of games developed using RTF.
Stimulation of murine peritoneal macrophage functions by neuropeptide Y and peptide YY. Involvement of protein kinase C. (1993)

The peptides neuropeptide Y (NPY) and peptide YY (PYY) at concentrations from 10(-12) M to 10(-8) M have been shown in this study to stimulate significantly, in vitro, several functions of resting peritoneal macrophages from BALB/c mice: adherence to substrate, chemotaxis, ingestion of inert particles (latex beads) and foreign cells (Candida albicans), and production of superoxide anion measured by nitroblue tetrazolium reduction. A dose-response relationship was observed, with a maximal stimulation of the macrophage functions studied at 10(-10) M. These effects seem to be produced by specific receptors for the neuropeptides studied in peritoneal macrophages. Whereas the two peptides induced no change of intracellular cyclic AMP, they caused a significant stimulation of protein kinase C (PKC) in murine macrophages. These results suggest that NPY and PYY produce their effects on macrophage function through PKC activation.
Chaperone-based procedure to increase yields of soluble recombinant proteins produced in E. coli (2007)

The engineered E. coli strains and the two-step procedure presented here led to a remarkable increase in the solubility of a various recombinant proteins and should be applicable to a wide range of target proteins produced in biotechnology.
Protection of digitally controlled inverter units in rapid prototyping applications (2005)

Mandatory and optional protection features of a modular power electronic inverter unit are described. Special attention is paid to the potential of using the digital system processing core in the implementation of these protection features. It is shown, however, that in rapid prototyping (RP) systems, there is an interesting option of using a digital interface between the RP system and the inverter to implement the protection features. Experimental results verify that such an interface enables the use of the inverter unit in system development based on hardware-in-the-loop (HIL) without the need for elaborate system simulations or validation, cutting development time considerably
Morfología del sistema reproductor masculino de Baeacris punctulatus (Thunberg) (Orthoptera: Acrididae) (2005)

Baeacris punctulatus, especie de importancia económica, tiene amplia distribución en América del Sur. En este trabajo se analiza la morfología de los órganos reproductivos internos del macho, mediante un estudio anatomo-histológico. La gónada masculina está constituida por 30 folículos, este número es constante en ambos testículos tanto en ejemplares silvestres como en los de cautiverio. Los testículos son de tipo ?fountain?, siendo esta la primera cita para los Melanoplinae. Se identificaron 14 pares de glándulas accesorias con diferentes tipos glandulares, cuya morfología y secreción se comparó con Locusta migratoria, Schistocerca gregaria, Melanoplus sanguinipes y Poecilocerus pictus. El conducto eyaculador presenta una estructura compleja, se observan variaciones en la morfología de sus diferentes regiones con respecto a especies de langostas migratorias de la familia Acrididae. La presencia de cámaras internas en el conducto eyaculador superior, crestas cuticulares en la región del túnel, perforaciones de la endocutícula en el conducto eyaculador inferior están relacionadas con la formación del espermatóforo.
Analysis of calcium homeostasis in fresh lymphocytes from patients with sporadic Alzheimer's disease or mild cognitive impairment (2013)

Alzheimer's disease (AD) is the most widespread, age-related neurodegenerative disorder. Its two subtypes are sporadic AD (SAD) of unknown etiology and genetically encoded familial AD (FAD). The onset of AD is often preceded by mild cognitive impairment (MCI). Calcium dynamics were found to be dysregulated in FAD models, but little is known about the features of calcium dynamics in SAD. To explore calcium homeostasis during the early stages of SAD, we investigated store-operated calcium entry (SOCE) and inositol triphosphate receptor (IP3R)-mediated calcium release into the cytoplasm in unmodified B lymphocytes from MCI and SAD patients and compared them with non-demented subjects (NDS). Calcium levels in the endoplasmic reticulum and both the rising and falling SOCE slopes were very similar in all three groups. However, we found that SAD and MCI cells were more prone to IP3R activation than NDS cells, and increases in calcium levels in the cytoplasm were almost twice as frequent in SAD cells than in NDS cells. MCI cells and SAD cells exhibited an enhanced magnitude of calcium influx during SOCE. MCI cells but not SAD cells were characterized by higher basal cellular calcium levels than NDS cells. In summary, perturbed calcium homeostasis was observed in peripheral cells from MCI and SAD patients. Thus, lymphocytes obtained from MCI subjects may be promising in the early diagnosis of individuals who will eventually develop SAD. However, no conclusions are made regarding SAD due to the limited number patients. This article is part of a Special Issue entitled: 12th European Symposium on Calcium.
Using boron cluster ion implantation to fabricate ultra-shallow junctions (2005)

B/sub 18/H/sub x//sup +/ and B ion implantation have been used to fabricate the SDE of pMOSFETs with gate lengths of /spl sim/60 nm. Ultra high resolution mass spectra of natural abundance B/sub 18/H/sub 22/ and mass 11 isotopically enriched B/sub 18/H/sub 22/ have been used to achieve deconvolution of the binominal distribution from ion states present in the cluster ion beam. The cluster source has been specifically designed to maintain the integrity of the cluster during the ionization process. The results of B/sub 18/H/sub x//sup +/ and B are compared from the viewpoint of transistor performance. The implants were performed at equivalent process energies and doses. It has been shown that B implantation greatly increases the throughput of low energy boron implants while delivering uncompromised device performance.
