Efficient coupled noise estimation for on-chip interconnects (1997)

Noise analysis and avoidance is an increasingly critical step in deep submicron design. Ever increasing requirements on performance have led to widespread use of dynamic logic circuit families and its other derivatives. These aggressive circuit families trade off noise margin for timing performance making them more susceptible to noise failure and increasing the need for noise analysis. Currently, noise analysis is performed either through circuit or timing simulation or through model order reduction. These techniques in use are still inefficient for analyzing massive amount of interconnect data found in present day integrated circuits. This paper presents efficient techniques for estimation of coupled noise in on-chip interconnects. This noise estimation metric is an upper bound for RC circuits, being similar in spirit to Elmore delay in timing analysis. Such an efficient noise metric is especially useful for noise criticality pruning and physical design based noise avoidance techniques.

BED THICKNESS AND GRAIN SIZE: GRADED BEDS (1966)

SUMMARY Data from Ordovician and Tertiary turbidites and from the Hekla ash fall show good correlation between bed thickness and grain size. Most of the thicker beds are coarser grained. The relation between bed thickness and grain size in graded beds can be explained by a theory which uses a sedimentation formula based on the decay law of turbulence in the deposition zone of a turbidity current.
Distributed arithmetic architectures for FIR filters-A comparative review (2017)

Finite impulse response (FIR) filter is an influential block in various signal processing applications. The complexities in VLSI implementation of FIR filters is dominated by the number of multiply and accumulate (MAC) operations. Distributed Arithmetic (DA) is an alternative technique where the MAC operations can be replaced by a series of look-up tables and addition operations. FIR filter based on DA are computationally efficient because of high degree of mechanization involved in the implementation of MAC operations using DA. Many reconfigurable and non-reconfigurable FIR filter architectures can be developed using DA. This paper reviews the existing FIR filter architectures based on DA. LUT based DA and LUT-less DA are the significant methods in the implementation of non-reconfigurable filters. This brief summarizes the area and power reports of the existing non-reconfigurable FIR filter architectures based on both LUT based DA and LUT-less DA. One dimensional and two dimensional systolic DA based architectures for FIR filter implementation are also briefed. DA based adaptive FIR techniques are explained. This paper presents the comparative results of FIR and adaptive FIR filter architectures in terms of area, power, area-delay product, minimum cycle period and energy per sample. This survey can form a basis for further research on DA based FIR filter architectures.
Standardizing appraisals for PV installations (2013)

As PV installations increase across the U.S., there will be a point when an appraiser will have the opportunity to value the PV system as part of a property sale or re-finance. Proper valuation techniques as applied to solar PV are necessary to reflect the increase in market demand for solar PV systems. Appraisers must follow the Uniform Standards of Professional Appraisal Practices (USPAP) when valuing solar PV systems, which means that appraisers must gain competency to 1) accurately recognize the value proposition of a PV system, and 2) develop the PV system's market value as it contributes to the property. The challenges currently faced by property owners with installed PV are whether the PV system adds market value to the property, and finding an appraiser with competency. Not all markets are the same, and PV market values will vary considerably based on many factors that include, but are not limited to the adoption rate in the particular market, the utility rate paid by the customer, the PV system's condition, aesthetics, and obsolescence. This paper will discuss how past challenges with respect to proper PV system valuation are being addressed in a standard fashion, along with the far-reaching benefits that may be available to future PV adopters as valuation concepts are ultimately recognized and adopted by valuation professionals, real estate agents, mortgage lenders and underwriters.
Chain Microstructure of Poly(Vinylidene Fluoride) by 282 MHz<sup>19</sup>F-NMR Spectroscopy (1989)

Abstract Based on the effects of solvent and temperature on the 282-MHz 19F-NMR spectrum of poly(vinylidene fluoride), PVF2, in perdeuterated dimethylacetamide (DMA-d9) solution at -20°C, nine minor CF2 resonances that are due to structures in the vicinity of reversed monomer enchainments have been identified. 19F-19 F spin-spin decoupling and two-dimensional 19F-correlation spectroscopy (19F-2D COSY) have been used to assign these resonances. In several cases these assignments differ from those made previously.
Threat Model for BGP Path Security (2014)

This document describes a threat model for the context in which
External Border Gateway Protocol (EBGP) path security mechanisms will
be developed. The threat model includes an analysis of the Resource
Public Key Infrastructure (RPKI) and focuses on the ability of an
Autonomous System (AS) to verify the authenticity of the AS path info
received in a BGP update. We use the term to refer to any
BGP path security technology that makes use of the RPKI. PATHSEC will
secure BGP, consistent with the inter-AS security focus of the RPKI.
The document characterizes classes of potential adversaries that are
considered to be threats and examines classes of attacks that might be
launched against PATHSEC. It does not revisit attacks against
unprotected BGP, as that topic has already been addressed in the BGP-4
standard. It concludes with a brief discussion of residual
vulnerabilities.
Why is primary prophylaxis underutilized in the United States? (2003)

This article discusses the issues that may contribute to utilization of prophylactic regimens and issues to consider when determining treatment programs for pediatric patients.
Machine Learning for Wind Turbine Blades Maintenance Management (2017)

Delamination in Wind Turbine Blades (WTB) is a common structural problem that can generate large costs. Delamination is the separation of layers of a composite material, which produces points of stress concentration. These points suffer greater traction and compression forces in working conditions, and they can trigger cracks, and partial or total breakage of the blade. Early detection of delamination is crucial for the prevention of breakages and downtime. The main novelty presented in this paper has been to apply an approach for detecting and diagnosing the delamination WTB. The approach is based on signal processing of guided waves, and multiclass pattern recognition using machine learning. Delamination was induced in the WTB to check the accuracy of the approach. The signal is denoised by wavelet transform. The autoregressive Yule–Walker model is employed for feature extraction, and Akaike’s information criterion method for feature selection. The classifiers are quadratic discriminant analysis, k-nearest neighbors, decision trees, and neural network multilayer perceptron. The confusion matrix is employed to evaluate the classification, especially the receiver operating characteristic analysis by: recall, specificity, precision, and F-score.
A Multi-Point Sensor Based on Optical Fiber for the Measurement of Electrolyte Density in Lead-Acid Batteries (2010)

This article describes a multi-point optical fiber-based sensor for the measurement of electrolyte density in lead-acid batteries. It is known that the battery charging process creates stratification, due to the different densities of sulphuric acid and water. In order to study this process, density measurements should be obtained at different depths. The sensor we describe in this paper, unlike traditional sensors, consists of several measurement points, allowing density measurements at different depths inside the battery. The obtained set of measurements helps in determining the charge (SoC) and state of health (SoH) of the battery.
Aptamers: from bench side research towards patented molecules with therapeutic applications (2009)

The development of aptamers into compounds with therapeutic and diagnostic compounds has resulted in patents protecting the sequences and the use of these oligonucleotides. Several of these patented aptamers are currently being tested in Phase I or II clinical trials. Moreover, an anti-VEGF aptamer has already been approved by the FDA for treatment of age-related macular degeneration in humans.
Interaction of B16 malignant melanoma tumor cells with the murine mesentery in vitro. (1988)

We have used organs cultures of murine mesentery as a model system to investigate the mechanisms by which B16-F10 melanoma cells invade normal tissues. The mesentery has the advantage of being a real tissue, consisting of a loose connective tissue, containing a normal complement of stromal cells and extracellular matrix, covered by a continuous epithelium of squamous mesothelial cells which are separated from the connective tissue by a laminin-containing basement membrane. B16-F10 cells seeded onto the mesentery in vitro cause a local retraction of the mesothelial cells exposing the underlying basement membrane onto which the tumor cells spread. Direct contact between the tumor cells and the margins of the mesothelial cells is required to induce retraction. Most of the B16 cells remain on the surface of the mesentery where they spread on the basement membrane without disrupting it. A few B16 cells penetrate the basement membrane and invade the connective tissue interior of the mesentery where they flatten out and assume a fibroblastic morphology. Tumor cells within the connective tissue may continue to translocate and they adhere to and move along the fibers of the connective tissue extracellular matrix without appearing to destroy or disrupt them.
The Amino Acid Sequence of Zinc-Carboxypeptidase from Streptomyces griseus (1990)

The amino acid sequence of a zinc-carboxypeptidase from S. griseus (Cpase SG) was determined by automated Edman degradation and carboxypeptidase digestion of the S-carboxymethylated protein and by sequence analyses of peptides produced by cyanogen bromide cleavage and by lysyl endopeptidase digestion of the S-carboxymethylated protein. This enzyme is characterized by a uniquely broad substrate specificity which combines the specificities of mammalian Cpase A and Cpase B (J. Biochem. 86, 683-694, 1979). Cpase SG consists of 328 amino acid residues. The amino acid sequence of Cpase SG is partially similar to those of bovine Cpase A and Cpase B (sequence identity, 28-29%). In the sequence of Cpase SG, residues that are functionally important in mammalian Cpase A and Cpase B were all found at the corresponding positions. Residue 255 (according to the numbering system for bovine Cpase A), which, in the other Cpases, contributes to the difference in specificity between Cpase A (Ile-255) and Cpase B (Asp-255), was Asp. However, residue 254 was Ile, in contrast to Ser or Thr in all of the forms of Cpase A and Cpase B examined to date. The increase in hydrophobicity caused by the change at position 254 and the presence of negative charge at position 255 is probably one of the reasons for the broad substrate specificity of Cpase SG.
The constituents of tomato fruit — the influence of environment, nutrition, and genotype (1981)

It is proposed to describe briefly the rise in popularity of the tomato during the 20th century to become the world's fourth most significant fruit, making an important contribution to human nutrition. The grading standards for fruit used in various major tomato-producing countries will be outlined. A major part of the review will be devoted to describing changes in composition during the maturation, ripening, preservation, and storage of good quality tomatoes especially as regards carbohydrates, organic and amino acids, proteins, steroids, pigments, minerals, and the lipids, volatiles, and other minor constituents. A range within which composition should normally fall will be given. Additionally, the effects on composition of environment, cultivar, nutrition, and physiological disorders inter alia will be described. How new growing methods and genetic manipulation could influence the tomato of the future will also be considered.
Synthesis and antibacterial properties of some novel 2-substituted-6-(4-methyl-6-substitutedcinnoline-3-yl)imidazo[2,1- b ][1,3,4]thiadiazoles (2010)

A series of 2-substituted-6-(4-methyl-6-substitutedeinnoline-3-yl)imidazo[2,1-b][1,3,4] thiadiazoles 5a-k have been synthesized by reacting 3-(2-bromoacetyl)-4-methyl-6-substitutedeinnolines 3 with various 2-amino-5-substituted-1,3,4-thiadiazoles 4 taking absolute ethanol as solvent. The structures of the newly synthesized compounds have been characterized by elemental analysis, IR and 1 H NMR spectral data. All the newly synthesized compounds have been tested for their antibacterial properties against gram-positive and gram-negative bacteria.
Innovative power generation systems using supercritical CO2 cycles (2017)

Supercritical carbon dioxide (sCO2) power cycle is an innovative concept for converting thermal energy to electrical energy. It uses sCO2 as the working fluid medium in a closed or semi-closed Brayton thermodynamic cycle. The sCO2 power cycles have several benefits such as high cycle efficiency, small equipment size and plant footprint (and therefore lower capital cost) and the potential for full carbon capture. Achieving the full benefits of the sCO2 cycle depends on overcoming a number of engineering and materials science challenges that impact both the technical feasibility of the cycle and its economic viability. For example, the design and construction methods of turbomachinery, recuperator and high-pressure oxy-combustor pose significant technical challenges. Other R&D needs include material selection and testing, and optimized power cycle configuration. Over the years, particularly in the last decade, R&D efforts have been growing worldwide to develop sCO2 cycle technologies for power generation. Significant progress has been made in developing sCO2 cycle power systems. Some small, low-temperature sCO2 Brayton cycle power systems are starting to emerge in the commercial market, and a natural gas-fired demonstration power plant using a sCO2 cycle called the Allam Cycle is under construction. This article describes the sCO2 cycles for applications in power generation from fossil fuels and reviews the recent developments in sCO2 power cycle technologies.
SELECTION FOR CAPTAN TOLERANCE IN THE <i>Rhizobium phaseoli-Phaseolus vulgaris</i> L. N<sub>2</sub>-FIXING SYMBIOSIS (1986)

Application of the seed-applied fungicides captan, DL-Plus, Evershield, thiram and Metalaxyl reduced nodulation in the field bean cultivar Lancer (Phaseolus vulgaris L.) in the field. Captan, Evershield, B3 and Thiram also lowered the acetylene reducing activity under the same conditions. Captan, DL-Plus, and B3 resulted in significant yield reductions of field bean inoculated with commercial multi-strain rhizobial inoculant. Since captan or captan-containing fungicides were the most potent inhibitors of symbiotic N 2 fixation in field bean, spontaneous mutants of Rhizobium phaseoli strains 3644 and 8215 were selected on the basis of ability to grow in microbial medium containing 100 ppm of Captan 50 W. Controlled environment chamber and field evaluations indicated that all mutants were less sensitive to commercial rates of Captan 50 W (2.0 g per kilogram seed) than either parent strain or commercial multi-strain inoculant. Inoculation of captan-treated seed with these mutants 24 h prior to seeding did not affect nitrogenase activity or yield. Assessment of the effect of captan on the N 2 -fixing symbiosis and the captan tolerance of R. phaseoli strains by the acetylene reduction assay or 15 N isotope dilution at levels of 15 N natural abundance gave similar results. The existence of mutants of R. phaseoli tolerant to seed-applied captan but unaltered in symbiotic properties makes the combined use of captan as a seed protectant and seed-applied rhizobial inoculation fully compatible. Key words: Phaseolus vulgaris L., Rhizobium phaseoli, captan, N 2 fixation, 15 N isotope dilution, acetylene reduction
Inhibitors of propagation of coagulation: factors V and X (2011)

Cardiovascular diseases are still the most important cause of morbidity and mortality in western countries and antithrombotic treatment is nowadays widely used. Drugs able to reduce coagulation activation are the treatment of choice for a number of arterial and/or venous thromboembolic conditions. Some of the drugs currently used for this purpose, such as heparins (UFH or LMWH) and VKA, have limitations consisting of a narrow therapeutic window and an unpredictable response with the need of laboratory monitoring in order to assess their efficacy and safety. These drawbacks have stimulated an active research aimed to develop new drugs able to act on single factors involved in the coagulation network, with predictable response. Intense experimental and clinical work on new drugs has focused on synthetic agents, which could preferably be administered orally and at fixed doses. The most advanced clinical development with new anticoagulants has been achieved for those inhibiting FXa and some of them, like fondaparinux, are already currently used in clinical practice. Other agents, such as rivaroxaban, apixaban, otamixaban and edoxaban are under development and have already been studied or are currently under investigation in large scale phase III clinical trials for prevention and treatment of venous thromboembolism, atrial fibrillation and acute coronary syndromes. Some of them have proved to be more effective than conventional therapy. Data on some agents inhibiting FVa are still preliminary and some of these drugs have so far been considered only in patients with disseminated intravascular coagulation secondary to sepsis.
A fast method for image noise estimation using Laplacian operator and adaptive edge detection (2008)

We present a simple and fast algorithm for image noise estimation. The input image is assumed to be corrupted by additive zero mean Gaussian noise. To exclude structures or details from contributing to the noise variance estimation, a simple edge detection algorithm using first-order gradients is applied first. Then a Laplacian operator followed by an averaging over the whole image will provide very accurate noise variance estimation. There is only one parameter which is self-determined and adaptive to the image contents. Simulation results show that the proposed algorithm performs well for different types of images over a large range of noise variances. Performance comparisons against other approaches are also provided.
COHORT DIFFERENCES ASSOCIATED WITH TRENDS IN SAT<sup>®</sup> SCORE AVERAGES (1991)

ABSTRACT The potential impact of cohort changes with regard to ethnic group, gender, class rank, and first language learned on yearly average Scholastic Aptitude Test (SAT) and Test of Standard Written English (TSWE) scores was studied. Regression and cross‐classification analyses were conducted on data from 1985, and 1987 to 1990. Both analyses adjusted test score means based on common cohorts of students. The analyses indicated that approximately half of the decline in SAT verbal (SAT‐V) scores was associated with cohort change. Average SAT mathematics (SAT‐M) scores could possibly have risen by three points, rather than remaining constant, if the 1987 and 1990 cohorts were the same.

Reward sensitivity in impulsivity (2004)

Impulsive individuals choose immediate small over delayed larger rewards, suggesting reward hypersensitivity. Single-unit studies have shown increased ventral tegmental activity to rewards and reward predictors and decreased activity when predicted rewards are withheld. The orbitofrontal ventral tegmental cortical target also responds to reward and expectation in single-unit and neuroimaging studies. The anterior P2a event-related potential component is a proposed index of reward-related orbitofrontal activity. In this reward prediction study in high and low impulsive subjects, the P2a localized to orbitofrontal cortex and was largest to non-predicted rewards and smallest in the absence of predicted rewards in subjects higher on self-reported impulsiveness, consistent with a P2a index of orbitofrontal reward processing and with reward hypersensitivity in impulsivity.
Relation of Helicobacter pylori infection and coronary heart disease. (1994)

In this pilot study the association of adult coronary heart disease with H pylori seropositivity suggests that the early childhood environment may be important in determining the risk of CHD in adult life. The association needs confirmation in other better designed studies. If H pylori itself is responsible for the association, then this is of great potential importance as the infection is treatable.
