On the position error bound in cooperative networks: A geometric approach (2008)

Location-awareness is of great importance in future wireless networks. In harsh environments or when only limited infrastructure is available, cooperation among nodes can yield significant performance benefits. To realize these benefits, it is crucial to understand the fundamental behavior of localization. The squared position error bound (SPEB), based on the information inequality, is a fundamental limit on the localization performance. Although the SPEB can be applied to any type of network topology and any transmission technology, it is not intuitive as a design tool. In this paper, we provide a novel geometric interpretation of the localization information, enabling new insights into how and when cooperation is beneficial, and how location-aware networks should be designed.

Analysis of Iodine-like (Chlorine) Flavor-causing Components in Brazilian Coffee with Rio Flavor (2011)

Green beans and roasted beans of coffee with Rio flavor were analyzed by gas chromatography-olfactometry to clarify the causal substances of Rio flavor in Brazilian coffee. In addition to 2,4,6-trichloroanisole (TCA) and 2,4,6-trichlorophenol (TCP), which are known as the main causal substances of Rio flavor, a new iodine-like flavor-causing compound, 2,6-dichlorophenol (DCP), was detected. The detected amounts of 2,6-DCP and 2,4,6-TCA were less than 0.1 and 0.1 ppb in Rio flavor-free coffee beans, 0.8 and 1.2 ppb in weak Rio flavored beans, and 3.0 and 2.6 ppb in strong Rio flavored beans, respectively. Musty and chlorine flavors were sensed more strongly in model coffee containing both 2,4,6-TCA and 2,6-DCP than in the coffee containing them individually. In the present study, 2,6-DCP was identified as a new causal substance of Rio flavor, and it was found that the presence of 2,4,6-TCA intensifies Rio flavor, as a synergy effect.
An integrated approach to three-dimensional information management with MACCS-3D (1991)

In the past decade, the scientific community has realized the value of three-dimensional (3D) structural information and '3D searching' has started to become an important new methodology for computer-aided drug design. During this time, molecular modeling information generated from various sources has proliferated due to the growing availability of software and hardware and the increasing use of crystallographic and spectroscopic techniques. This information needs to be organized to allow for its effective storage and retrieval. This paper presents an approach to address this problem with a recently introduced program, MACCS-3D. In particular, this approach utilizes MACCS-3D's capability of handling data specific for atoms and atom pairs. With this software, various biological, computational, and spectroscopic data can be merged, allowing scientists from different disciplines to access and use this information more efficiently.

A single high dose of dexamethasone affects the phosphorylation state of glutamate AMPA receptors in the human limbic system (2016)

Glucocorticoids (GC) released during stress response exert feedforward effects in the whole brain, but particularly in the limbic circuits that modulates cognition, emotion and behavior. GC are the most commonly prescribed anti-inflammatory and immunosuppressant medication worldwide and pharmacological GC treatment has been paralleled by the high incidence of acute and chronic neuropsychiatric side effects, which reinforces the brain sensitivity for GC. Synapses can be bi-directionally modifiable via potentiation (long-term potentiation, LTP) or depotentiation (long-term depression, LTD) of synaptic transmission efficacy, and the phosphorylation state of Ser831 and Ser845 sites, in the GluA1 subunit of the glutamate AMPA receptors, are a critical event for these synaptic neuroplasticity events. Through a quasi-randomized controlled study, we show that a single high dexamethasone dose significantly reduces in a dose-dependent manner the levels of GluA1-Ser831 phosphorylation in the amygdala resected during surgery for temporal lobe epilepsy. This is the first report demonstrating GC effects on key markers of synaptic neuroplasticity in the human limbic system. The results contribute to understanding how GC affects the human brain under physiologic and pharmacologic conditions.

Epidemiology of Human Papillomavirus Infection (2000)

Anogenital human papillomavirus (HPV) infection is a sexually transmitted disease (STD) that typically follows a self-limiting transient course for both sexes. The HPV incidences and prevalences vary greatly, because they reflect the sexual activity of the individuals studied and of the population they are in contact with. Higher prevalences are seen in young, sexually active groups and in high-risk areas for cervical and penile cancer, e.g. in Colombia. There has also been an increasing trend with time in Western Europe, paralleling the spread of other STDs and changes in sexual behavior. Penile intraepithelial neoplasia is usually positive for high-risk HPV DNA, mostly of type 16, whereas only approximately 50% of invasive penile cancers are positive for HPV DNA. This is similar to the role of high-risk HPV in vulvar carcinoma, where the attributable proportion is also approximately 40-50%. Moreover, in both sites similar histologic types of squamous cell carcinoma, i.e. the basoloid and basaloid/warty types, are mainly associated with high-risk HPV types. The studies performed so far have indicated that HPV has an etiological role in penile cancer, although the attributable proportion may be only approximately 40-50%.
Exposure to<sup>16</sup>O-Particle Radiation Causes Aging-Like Decrements in Rats through Increased Oxidative Stress, Inflammation and Loss of Autophagy (2011)

Exposing young rats to particles of high energy and charge (HZE particles), a ground-based model for exposure to cosmic rays, enhances indices of oxidative stress and inflammation, disrupts the functioning of neuronal communication, and alters cognitive behaviors. Even though exposure to HZE particles occurs at low fluence rates, the cumulative effects of long-term exposure result in molecular changes similar to those seen in aged animals. In the present study, we assessed markers of autophagy, a dynamic process for intracellular degradation and recycling of toxic proteins and organelles, as well as stress and inflammatory responses, in the brains of Sprague-Dawley rats irradiated at 2 months of age with 5 and 50 cGy and 1 Gy of ionizing oxygen particles ((16)O) (1000 MeV/n). Compared to nonirradiated controls, exposure to (16)O particles significantly inhibited autophagy function in the hippocampus as measured by accumulation of ubiquitin inclusion bodies such as P62/SQSTM1, autophagosome marker microtubule-associated protein 1 beta light chain 3 (MAP1B-LC3), beclin1 and proteins such as mammalian target of rapamycin (mTOR). The molecular changes measured at short (36 h) and long (75 days) intervals after (16)O-particle exposure indicate that the loss of autophagy function occurred shortly after exposure but was recovered via inhibition of mTOR. However, HZE-particle radiation caused significant sustained loss of protein kinase C alpha (PKC-α), a key G protein modulator involved in neuronal survival and functions of neuronal trophic factors. Exposure to (16)O particles also caused substantial increases in the levels of nuclear factor kappa B (NF-κB) and glial fibrillary acidic protein (GFAP), indicating glial cell activation 75 days after exposure. This is the first report to show the molecular effects of (16)O-particle radiation on oxidative stress, inflammation and loss of autophagy in the brain of young rats.
Efficient determination of multiple regularization parameters in a generalized L-curve framework (2002)

The selection of multiple regularization parameters is considered in a generalized L-curve framework. Multiple-dimensional extensions of the L-curve for selecting multiple regularization parameters are introduced, and a minimum distance function (MDF) is developed for approximating the regularization parameters corresponding to the generalized corner of the L-hypersurface. For the single-parameter (i.e. L-curve) case, it is shown through a model that the regularization parameters minimizing the MDF essentially maximize the curvature of the L-curve. Furthermore, for both the single-and multiple-parameter cases the MDF approach leads to a simple fixed-point iterative algorithm for computing regularization parameters. Examples indicate that the algorithm converges rapidly thereby making the problem of computing parameters according to the generalized corner of the L-hypersurface computationally tractable.
MECHANISMS OF ENERGY TRANSFER INVOLVING TRIVALENT Tb AND Eu (1966)

Excitation can move from Tb to Eu at 4.2°K by processes involving exchange even though the electronic transitions concerned are not matched in energy. At 295°K, thermal effects cause an overlap permitting dipole-dipole transfer to occur. Transfer to Eu may be enhanced by excitation migration from more remote Tb ions to those closer to Eu at 295°K. This migration is not effective at 4.2°K, and hence appears to require thermal activation.

Parallelization of multimedia applications on the multi-level computing architecture (2011)

The Multi-Level Computing Architecture (MLCA) is a novel parallel System-on-a-Chip architecture targeted for multimedia applications. It features a top level controller that automatically extracts task level parallelism using techniques similar to how instruction level parallelism is extracted by superscalar processors. This allows the MLCA to support a simple programming model that is similar to sequential programming. In order to assist programmers to easily and efficiently port multimedia applications to the MLCA programming model, a compilation environment is designed. This compilation environment enhances parallelism in MLCA programs by applying three simple code transformations that are based on known compiler optimizations. In this paper, we describe the MLCA architecture, its programming model, its compilation environment and an evaluation of its performance. Our experimental evaluation with three real multimedia applications and an MLCA simulator shows that the MLCA is a viable architecture and scaling speedups can be obtained using the compilation environment with little programmer effort.

Local Tool Wear Prediction Using Physics-Based Models (2008)

A semi-empirical model based on the physics behind tool wear that can depict the tool wear locally is developed to predict crater profiles of multilayer coated carbides. Dissolution and abrasion relationships are recast into a point-wise or local version to predict directly based on the temperature and pressure profiles from FE simulation. The approach is reasonable to explain the crater profiles observed in multilayer coated carbides. However, the model deviates from the real profiles due to the κ-to-α phase transformation in the middle Al2O3 layer, the change in the friction conditions as each layer is exposed, and the combined wear resistance of multi-layers of the cutting tool.

Correction of time base error for high speed sampling oscilloscope (2013)

In order to improve the accuracy of measurement the correction of time base error of oscilloscope is essential. In this paper we studied time base error. There are three kinds of time base error including time base drift, time base jitter and time base distortion. Reason of time base error causes and the influence for measurement and calibration, the method for correction or compensation were studied. We also had good results as we process the experiment data which proofed the method in this paper were right.
Optically generated true-time delay in phased-array antennas (1995)

This tutorial review paper deals with various methods for solving a basic problem of wideband phased arrays, i.e. beam squinting, using optical technologies. The problem of beam squinting in phased arrays is analyzed and the concept of true-time delay is introduced. The advantages of realizing variable delay lines by optical rather than by microwave means are reviewed, together with principles of operation. Among the techniques described are switched-path length delay lines, fiber stretchers, tunable lasers with highly dispersive fiber, and coherent techniques incorporating dispersive delay. Recent experimental results are discussed in the light of practical system requirements.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

MEMS energy harvesting device driven by ambient vibrations (2015)

An efficient method for energy harvesting through MEMS based devices, driven by ambient vibrations is presented. This particular method relies on the utilization of time varying magnetic fields to induce electromotive forces which in turn drive current through coils fabricated on a substrate. This allows for the conversion of energy contained within naturally occurring vibrations to usable forms of electrical energy. The process primarily hinges on fundamental principals in electromagnetic theory related to induction. Here we propose a miniaturized MEMS energy harvester comprising of coils on a substrate measuring mere mm in dimension, two permanent magnets and a shuttle that is connected to flexible beams. The relationship between number of coil turns on the substrate, induced voltage and vibrational motion were studied and a proposed model was devised.

Corrosion Protection of Untreated AA‐2024‐T3 in Chloride Solution by a Chromate Conversion Coating Monitored with Raman Spectroscopy (1998)

The behavior of chromate conversion coatings (CCCs) on the aluminum aircraft alloy AA 2024-T3 was examined by several types of experiments, using Raman spectroscopy as a primary technique. First, Raman spectra of the CCC film made from a commercial process revealed a Raman feature characteristic of Cr(VI) which was distinct from Raman bands of pure CrO4^−2 or Cr2O7^−2. Second, Raman spectroscopy was used to monitor migration of chromate species from a CCC film to an initially untreated alloy sample. The release of chromate from a CCC was demonstrated, as was redeposition of a chromate film on the fresh alloy surface. Formation of a Raman-observable Cr(VI)-containing deposit was more rapid in or near pits in the untreated alloy sample, and the deposit was spectroscopically very similar to the original CCC film. The initially untreated alloy became much less active toward corrosion after migration of chromate from the nearby CCC film, with the polarization resistance increasing by at least two orders of magnitude and the pitting potential increasing by 60 mV. The results clarify the mechanism of self-healing exhibited by CCC films, in which chromate species released from the CCC migrate to an actively corroding region and stop aluminum dissolution. The migrating chromate is selectively deposited at active corrosion sites, either by forming an insoluble Al/chromate is selectively deposited at active corrosion sites, either by forming an insoluble Al/chromate precipitate or by adsorption by previously formed corrosion.
VLSI Design for Reliability-Hot Carrier Effects (1993)

This report describes the accomplishments during the contract period (June 28, to June 27, 1992) on the computer aided analysis of CMOS device and circuit degradation due to hot-carrier effects. The task involved four subtasks: (1) simulation of gate oxide degradation during long-term circuit operation; (2) determination of overall circuit performance after hot-electron stress; (3) probabilistic timing approach to hot-carrier-effect estimation; (4) parametric macromodeling of hot-carrier-induced degradation in MOS VLSI circuits. The first two parts are continued subtasks while the latter two are new subtasks. In order to simulate the reliability of MOS circuits, both the detailed model and the macromodel are used; the detailed model is used for accurate analysis of small circuits and the macromodel is used for very large circuits for computational efficiency. Since the hot-carrier-induced aging of MOS circuits is input-pattern dependent, an important task is to develop a computationally efficient probabilistic timing approach to hot-carrier-effect estimation without resorting to the Monte Carlo simulation. We have developed a new probabilistic approach that accounts for cumulative effects of all input waveform combinations in a single run. VLSI reliability, Hot-carrier effects, Computer aided design.
Mass spectrometry detection and reduction of disulfide adducts between reducing agents and recombinant proteins with highly reactive cysteines. (1999)

Recombinant proteins with highly reactive thiol groups can form disulfide adducts with reducing agents commonly used in protein purification, such as beta-mercaptoethanol and dithiothreitol. These adducts can interfere with protein-protein or protein-ligand interactions.This report describes the reduction of persistent disulfide adducts between the reducing agents glutathione or beta-mercaptoethanol and the recombinant protein Cyto-MelCAM, which were detected using matrix-assisted laser desorption and ionization (MALDI) mass spectrometry.These adducts were effectively reduced using the trialkylphosphine reducing agent tris(2-carboxyethyl) phosphine hydrochloride.
