A three-frequency scatterometer technique for the measurement of ocean wave spectra (1991)

A microwave technique for the measurement of ocean wave spectra has been compared with wave gauge output during extensive field testing. The method is based on the dual-frequency technique for detecting long ocean waves by matching the modulation of short waves with the beat wavelength between two transmitted microwave frequencies. The new method, however, utilizes three microwave frequencies in order to reduce mean backscatter not related to short-wave modulation. Two prototype scatterometers have been built using three frequencies at L-band and at K/sub u/-band. Wave spectra have been measured by both radar systems which, when properly normalized, agree well with simultaneous in situ measurements taken by conventional wave gauges at the pier site. Thirteen sets of spectra have been computed, five of which correspond to a situation in which a local wind sea was generated and then decayed. The present experiment does not demonstrate the directionality of this new technique.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Return-Oriented Programming without Returns on ARM (2010)

In this paper we present a novel and general memory-related attack method on ARM-based computing platforms. Our attack deploys the principles of return-oriented programming (ROP), however, in contrast to conventional ROP, it exploits jumps instead of returns, and hence it can not be detected by return address checkers. Although a similar attack has been recently proposed for Intel x86, it was unclear if the attack technique can be deployed to ARM-based computing platforms as well. Developing a jump-based attack on ARM is more involved, because ARM is based on a RSIC architecture which differs in many aspects from Intel’s x86 architecture. Nevertheless, we show a Turing-complete attack that can induce arbitrary change of behavior in running programs without requiring code injection. As proof of concept, we instantiate our attack method on the Android platform. 1
Steric aspects of adrenergic drugs. IX. Pharmacologic and histochemical studies on isomers of cobefrin (alpha-methylnorepinephrine). (1968)

Isomers of cobefrin (α-methylnorepinephrine) and related agents were studied on rat vas deferens. D(-)-cobefrin and (±)- erythro -N-methylcobefrin act directly, whereas L(+)-cobefrin, (±)-threocobefrin, (+)-desoxycobefrin, (-)-desoxycobefrin and (±)- threo -N-methylcobefrin produce very little effect on reserpine-pretreated tissues. On the normal vas deferens (+)-desoxycobefrin is more active than L(+)-cobefrin. On guinea-pig trachea, all agents except (-)-desoxycobefrin and L(+)-cobefrin are directly acting. Stereochemical considerations for direct vs. indirect drug effects and alpha vs. beta adrenergic effects are discussed. The catecholamine-fluorescence technique of Falck was used to demonstrate the reserpine-resistant neural uptake and retention of these isomers in the rat iris. D(-)-Cobefrin, L(+)-cobefrin and (±)- erythro -N-methylcobefrin are taken up and retained by adrenergic nerves, whereas (±)- threo cobefrin and (±)- threo -N-methylcobefrin do not show these characteristics. When studied similarly, after (+)-desoxycobefrin, adrenergic nerves and their varicosities showed more fluorescence than after (-)-desoxycobefrin. This tends to support the concept that during biotransformation (-)-α-methyldopa is converted to (+)-desoxycobefrin, which is β-hydroxylated to D(-)-cobefrin.

Expression and function of semaphorin 7A in bone cells (2005)

In the present study, we have investigated its regulation and function in bone cells. Semiquantitative reverse transcriptase-PCR demonstrated that Sema-7A mRNA is present during all stages of osteoblast differentiation and maturation in mouse calvaria cells and in MC3T3 cell line in vitro. Its expression is also regulated during primary osteoclast differentiation in vitro. We report that Sema-7A is capable of increasing the migration of MC3T3 cells and that this process is mediated by the mitogen-activated protein kinase pathway in osteoblasts, probably through the integrin subunit beta1. Moreover, the addition of recombinant soluble Sema-7A to the culture enhances osteoclast fusion. These findings indicate for the first time the possible involvement of Sema-7A in bone cell differentiation.
Resonance light scattering from a liquid suspension of microspheres (1986)

Resonance light scattering (RLS) spectra have been obtained from a liquid suspension of dielectric microspheres a narrow size distribution to find the mean diameter and standard deviation of the size spheres with Comparison with single-particle spectra shows that most peaks in the size-distributed spectra are due to several resonances in the an or bn Mie scattering coefficients. A good estimate of the mean diameter, obtained by matching experimental peak wavelengths with those calculated from Mie scattering formulas, agrees, well with optical microscopy and scanning electron microscopy results. However, the RLS-measured standard deviation of the size distribution is less than half of that from optical microscopy and transmission electron microscopy. Several sources of experimental error which affect the RLS spectra, including scattering angle uncertainty and oversized acceptance aperture, are discussed.
<title>Three-dimensional control of crystal growth using magnetic fields</title> (1993)

Two coupled systems of partial differential equations governing three-dimensional laminar viscous flow undergoing solidification or melting under the influence of arbitrarily oriented externally applied magnetic fields have been formulated. The model accounts for arbitrary temperature dependence of physical properties including latent heat release, effects of Joule heating, magnetic field forces, and mushy region existence. On the basis of this model a numerical algorithm has been developed and implemented using central differencing on a curvilinear boundary-conforming grid and Runge-Kutta explicit time-stepping. The numerical results clearly demonstrate possibilities for active and practically instantaneous control of melt/solid interface shape, the solidification/melting front propagation speed, and the amount and location of solid accrued.
Role of oxidative stress and nitric oxide in atherothrombosis (2008)

During the last decade basic and clinical research has highlighted the central role of reactive oxygen species (ROS) in cardiovascular disease. Enhanced production or attenuated degradation of ROS leads to oxidative stress, a process that affects endothelial and vascular function, and contributes to vascular disease. Nitric oxide (NO), a product of the normal endothelium, is a principal determinant of normal endothelial and vascular function. In states of inflammation, NO production by the vasculature increases considerably and, in conjunction with other ROS, contributes to oxidative stress. This review examines the role of oxidative stress and NO in mechanisms of endothelial and vascular dysfunction with an emphasis on atherothrombosis.
Face-to-Face, Email and Instant Messaging in Distributed Agile Software Development Project (2011)

This paper presents our preliminary results from a single case study on face-to-face, email and instant messaging (IM) communication in a distributed agile software development (DASD) project. The project had 13 team members during the time of study, and it was distributed between three different sites: Finland, Norway and Czech Republic. The team was using Scrum process model with three week sprints. We studied face-to-face communication with sociometric badges and email and IM communication by analyzing the project-related communication logs provided by each individual team member. We were interested both in the amount of communication and the communication patterns via different communication media. We found differences in the daily variation of communication amounts across different media as well as different network structure of communication with different media. Specifically, we found some evidence that IM is used as a replacement for face-to-face discussion in DASD, and that email seems to be more suitable for team-wide, inter-site communication than face-to-face or instant messaging.
The [4 + 3]-Cycloaddition/Quasi-Favorskii Process. Synthesis of the Carbocyclic Core of Tricycloclavulone (2005)

[reaction: see text] The [4 + 3]-cycloadduct derived from the reaction of 2,5-dibromocyclopentanone with cyclopentadiene was converted via a quasi-Favorskii rearrangement and ring-opening, ring-closing metathesis sequence to the carbocyclic core of the prostanoid tricycloclavulone.
Complexity Reduction Methods for Fractal Image Compression (1997)

Abstract Fractal image compression allows fast decoding but suffers from long encoding times. During the encoding a large number of sequential searches through a list of domains (portions of the image) are carried out while trying to find a best match for another image portion called range. In this article we review and extend the methods that have been developed to reduce the time complexity of this searching. Also we present a new taxonomy of the methods, provide an evaluation and propose two new techniques.
Stable solvates in solution of lithium bis(trifluoromethylsulfone)imide in glymes and other aprotic solvents: Phase diagrams, crystallography and Raman spectroscopyElectronic supplementary information (ESI) available: Crystallographic data (single crystal data) in cif format (CCDC reference number 184345). See http://www.rsc.org/suppdata/cp/b2/b203776a/ (2002)

Lithium bis(trifluoromethylsulfone)imide (LiTFSI), a promising electrolyte for high energy lithium batteries, forms several stable solvates having low melting points in aprotic solvents. In a previous study (D. Brouillette, G. Perron and J. E. Desnoyers, J. Solution Chem., 1998, 27, 151), it was suggested, based on thermodynamic studies, that such stable solvates may persist in solution and influence their properties. To verify this hypothesis, phase diagrams and Raman spectra have been measured for solutions of LiTFSI in acetonitrile, propylene carbonate and glymes (n(ethyleneglycol) dimethyl ether or Gn), which have the chemical structure CH3–O–(CH2–CH2–O)n–CH3 for n = 1 to 4 and 10. The relative intensities of the LiTFSI and solvent Raman bands are proportional to the concentration for systems without solvates. The systems for which stable solvates were identified in the phase diagram show important changes in the relative intensities for both the LiTFSI and the solvent Raman bands at concentrations corresponding to particular stoichiometries and support the conclusion that stable solvates are present in the solutions. The structure of the crystalline G1:LiTFSI solvate was determined by X-ray crystallography. Structures for (G2)2:LiTFSI and (G1)3:LiTFSI solvates are proposed.

A New Approach for Time Synchronization in Wireless Sensor Networks: Pairwise Broadcast Synchronization (2008)

This letter proposes an energy-efficient clock synchronization scheme for Wireless Sensor Networks (WSNs) based on a novel time synchronization approach. Within the proposed synchronization approach, a subset of sensor nodes are synchronized by overhearing the timing message exchanges of a pair of sensor nodes. Therefore, a group of sensor nodes can be synchronized without sending any extra messages. This paper brings two main contributions: 1. Development of a novel synchronization approach which can be partially or fully applied for implementation of new synchronization protocols and for improving the performance of existing time synchronization protocols. 2. Design of a time synchronization scheme which significantly reduces the overall network-wide energy consumption without incurring any loss of synchronization accuracy compared to other well-known schemes.
Inhibition of Osteogenesis In Vitro by a Cigarette Smoke‐Associated Hydrocarbon Combined With <i>Porphyromonas gingivalis</i> Lipopolysaccharide: Reversal by Resveratrol (2004)

Smoke-derived aryl hydrocarbons and bacterial LPS may act additively to inhibit bone formation. The findings may explain, in part, why net periodontal bone loss is greater and bone healing is less successful in smokers than non-smokers with periodontal infections. Reversal of the inhibitory effects in vitro by resveratrol suggests that this phytoalexin should be studied further for its potential therapeutic value, given its aryl hydrocarbon receptor antagonism and apparent anti-inflammatory activity.
The future development of nuclear medicine (1973)

Nuclear medicine is defined as “the application of nuclear physics to medical investigation”, therapy and radiobiology being thus excluded. A brief summary of the development of the subject is succeeded by suggestions concerning the probable future role of nuclear medicine in an integrated medical scientific service. It is thought that this is its proper place rather than as an independent medical speciality. Instrumentation is not specifically considered but allusion is made to the likely contribution of further research into radiopharmaceuticals and of the need to exploit the established importance of cyclotron-produced nuclides by the provision of isotope production cyclotrons in major nuclear medicine centres.
Food Applications and Physiological Effects of Anthocyanins as Functional Food Ingredients~!2009-10-26~!2010-01-06~!2010-03-09~! (2010)

Anthocyanins have been suggested as promising dietary compounds with an important role in human health. They are the largest group of water-soluble pigments in the plants, which are responsible for the red, purple and blue hues evident in fruits, vegetables, flowers and grains. As natural compounds of vegetables, fruits and red wines, anthocyanins are estimated to be widely consumed by humans with the estimated daily intake about 12.5 mg/d in the United States. Interest in anthocyanin-rich foods and extracts has intensified recently because of their possible health benefits. Anthocyanins have been shown to be potent antioxidants as well as anti-diabetic, anti-carcinogenic and having ocular effects among others. Findings of their beneficial health effects support their role as natural food colorants, functional foods and dietary supplements. The present article summarizes our knowledge on the bioavailability, antioxidant activity and healthenhancing components of anthocyanin-rich foods and extracts. In addition, their current and potential use as a natural food colorant, functional food and dietary supplement in the food and beverage industry is discussed.
Wave Attenuation of Reef Structures (1987)

The results of a preliminary field experiment to investigate the attenuation of waves as they propagate across reef structures is presented. The breaking process on the reef edge causes a marked alteration in the spectral shape with a broad spectrum with no distinct peak resulting. The wave height on the reef flat is found to be depth limited. Behind the reef flat the spectrum rapidly reforms into a typical JONSWAP form.
Dodecamer DNA Duplex Formation Is Characterized by Second-Order Kinetics, Positive Activation Energies, and a Dependence on Sequence and Mg<sup>2+</sup> Ion Concentration (2008)

This study provides quantitative information about the kinetics of formation of a complex between DNA oligomers having 12 bp. The DNA dodecamers were designed in such a way as to avoid the formation of hairpins or slipped duplex structures within single strands. The hybridization was carried out employing stopped-flow techniques. The reaction was studied in different buffers (phosphate or cacodylate), in the presence and absence of Mg2+ ions, and at different temperatures. Under all conditions, the reaction followed second-order kinetics. The association rate constants were on the order of 106 M(-1) s(-1) and were found to increase with an increase in temperature. Both the rate constants and the positive activation energies of the two dodecamers, which differ only by the presence of the TAGG tetrad either at the 3'end or at the 5' end, turned out to be significantly different. The presence of Mg2+ ions had a profound influence on the kinetics of association of either compound by substantially decreasing the activation energy of the process. The dependence on sequence of the kinetics of hybridization was manifest in all parameters under all the experimental conditions.

Aminoacyl-<i>S</i>-Enzyme Intermediates in β-Hydroxylations and α,β-Desaturations of Amino Acids in Peptide Antibiotics (2001)

Many of the alpha-amino acids found in proteins are shunted into microbial secondary metabolism to form peptide antibiotics by specific oxidation, including hydroxylation, at the beta carbon. Examples for the enzymatic hydroxylation of tyrosine and histidine and for desaturation of proline during covalent attachment as aminoacyl-S-pantetheinyl enzyme intermediates suggest a general strategy in peptide antibiotic biosynthesis.
Microfluidic and nanofluidic phase behaviour characterization for industrial CO<sub>2</sub>, oil and gas (2017)

Microfluidic systems that leverage unique micro-scale phenomena have been developed to provide rapid, accurate and robust analysis, predominantly for biomedical applications. These attributes, in addition to the ability to access high temperatures and pressures, have motivated recent expanded applications in phase measurements relevant to industrial CO<sub>2</sub>, oil and gas applications. We here present a comprehensive review of this exciting new field, separating microfluidic and nanofluidic approaches. Microfluidics is practical, and provides similar phase properties analysis to established bulk methods with advantages in speed, control and sample size. Nanofluidic phase behaviour can deviate from bulk measurements, which is of particular relevance to emerging unconventional oil and gas production from nanoporous shale. In short, microfluidics offers a practical, compelling replacement of current bulk phase measurement systems, whereas nanofluidics is not practical, but uniquely provides insight into phase change phenomena at nanoscales. Challenges, trends and opportunities for phase measurements at both scales are highlighted.
Identification of the promoter regions and Ï<sup>s</sup>-dependent regulation of the<i>gadA</i>and<i>gadBC</i>genes associated with glutamate-dependent acid resistance in<i>Shigella flexneri</i> (2003)

Resistance to killing by low pH is a common feature of both Escherichia coli and Shigella flexneri. The most effective E. coli acid resistance system utilizes two isoforms of glutamate decarboxylase encoded by gadA and gadB, and a putative glutamate/gamma-amino butyric acid antiporter encoded by gadC. Expression of the gad system is dependent upon the alternate sigma factor, sigma(s). We confirm that gadA, gadB, and gadC are also all dependent upon sigma(s) for their expression in S. flexneri. -10 sequences similar to the sigma(s)-10 consensus sequence were identified by primer extension in the upstream promoters of all three genes and the transcriptional start points were identical in both E. coli and S. flexneri.
New method of global planarization for Si ULSI (2002)

In this paper, a new method for obtaining global planarization of patterned Si ULSI wafers is described. This method is unique in that it is very simple, clean, and potentially high throughput. Here we report on the excellent planarization results obtainable. The key idea is a contact scheme for applying and planarizing a sacrificial layer over the patterned wafer. A critical element has been the use of an optical flat coated with a monolayer of release agent.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Sinusoidal Steady-state Analysis (1993)

This chapter not only deals with a.c. applications of techniques dealt with in the work on d.c. circuits, but deals with other circuit theorems particularly appropriate to a.c. circuit analysis. In particular, the application of complex numbers to electric circuits; the theory of complex numbers is covered in chapter 15, where the reader can study this and other mathematical techniques appropriate to electrical and electronic engineering.
Beneficial Effects of Costimulatory Blockade with Anti-Inducible Costimulator Antibody in Conjunction with CTLA4Ig on Prevention of Islet Xenograft Rejection from Rat to Mouse (2004)

These findings demonstrate that cellular rather than humoral immune responses are considered responsible for islet-xenograft rejection from rat to mouse and that the blockade of costimulatory signals with anti-ICOS antibody in conjunction with CTLA4Ig has a favorable effect on prevention of islet xenograft rejection.
Bacterial microencapsulation with three algal polysaccharides (1997)

Methods for encapsulating pollutant-degrading bacteria into microbeads of carrageenan type I, carrageenan type II, and guar gum are described. Cell suspensions in solutions of encapsulating agents were passed through a low-pressure nozzle into an aqueous medium. The resultant aerosols polymerized to form microbeads that ranged in diameter from 2–70 μm. Pentachlorophenol degradation experiments with an encapsulated Sphingomonas sp. showed degradation rates similar to those seen using free cells. These results describe three additional matrices for the microencapsulation of bacteria that have potential for use in bioremediation processes.Key words: Sphingomonas, pentachlorophenol, immobilization, encapsulation, bioremediation.
