THE DRAINAGE PATTERN OF THE LOWER OTTAWA VALLEY (1962)

Avant de se jeter dans le Saint‐Laurent, la Rivière Ottawa s'élargit pour former le Lac des Deux Montagnes, qui traverse la masse précambrienne dont sont constitéts les Monts Oka et Rigaud. L'auteur suggère que l'ancetre de la Rivière Ottawa avait probablement un cours moins anormal, qui passait entre le Mont Oka et le rebord du Bouclier Canadien. Le Mont Oka pose un obstacle au passage direct des eaux coulant du Nord vers le lac. La Rivière du Nord se déverse dans le lac prés de la tete de ce dernier et les affluents de cette rivière drainent une large portion du territoire situè entre le Mont Oka et le rebord du Bouclier. Ce réseau hydrographique subit l'influence marquée d'un groupe de collines morainiques parallèles, à demi submergées par les dépots plus récents de la Mer Champlain. Les Rivières Rigaud et Raquette sont les principaux affluents méridionaux. Cette dernière occupe une vallée préexistante creusée dans le roc du flanc est du Mont Rigaud. Le réseau hydrographique a pris forme lors du retrait de la Mer Champlain qui, aux derniers stages du Wisconsin, submergeait cette région à une profondeur de 600 pieds. Le rehaussement de la croute terrestre fut plus considérable dans la partie nord‐est que dans le secteur sud‐ouest du territoire; durant cette période de relèvement, la vallée de l'Ottawa assurait la décharge des eaux du haut bassin des Grands Lacs. Les affluents de la Riviére Ottawa creusèrent des vallées à divers niveaux d'élévation; il est possible de retracer ces anciens lits en divers points du territoire et de les rattacher aux terraces littorales accrochées aux flancs du bassin du Lac des Deux Montagnes. Maints cours d'eau actuels empruntent ces vallées, bien que, dans plusieurs cas, les rehaussements inégaux aient causé un renversement dans la direction de l'écoulement. Ce dernier phénomène est trés visible dans le tracé suivi par la Rivière du Nord, le long du rebord du Bouclier, entre Saint‐Jèrome et Lachute.
Millimeter-wave interferometric imaging sensors (2013)

Interferometric imaging holds the potential for significant improvements in capability for compact, close range millimeter-wave imaging sensors. This paper reviews the fundamental principles of interferometric imaging. Standard imaging array designs and their effect on resulting images are discussed, and simulated reconstructions of notional scenes are presented.
Yield modeling from SRAM failure analysis (1990)

Yield models based on Poisson, bose-Einstein, and binomial statistics are compared for a 1.25 mu m CMOS process. A mixed binomial yield model is shown to most accurately describe experimental yield data for a 1.25- mu m CMOS process. The model consists of gross yield and random yield components based on gross and random defects determined on a per level basis from a static random access memory-test element group (SRAM-TEG) yield vehicle failure analysis. The random yield component consists of both binomial and negative binomial segments, hence the mixed terminology, depending on whether or not a given defect shows evidence of clustering. Simple negative binomial models become optimistic at larger chip sizes by ascribing too much importance to interlevel effects of defect clustering. Using defect size distributions measured on a per level basis, the model is shown to hold over chip variations in feature size, product type, and chip area.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
T-diodes - a novel plug-and-play wideband RF circuit ESD protection methodology (2007)

A novel "plug-and-play" ESD protection methodology for wideband RF applications is demonstrated. This methodology utilizes an integrated transformer together with classical ESD protection elements. As a demonstrator, a wideband RF LNA in 0.18 mum CMOS is protected above 4.5 kV HBM without degrading its bandwidth.
Interactions of retinol with binding proteins: implications for the mechanism of uptake by cells (1990)

The kinetic parameters of the interaction of retinol with retinol binding protein (RBP) were studied. The rate constant for association of retinol with the protein (ka) was found to be 1.5 X 10(6) M-1 min-1. The rate constant for dissociation (kd) from the protein was determined by studying the transfer of retinol from RBP to lipid bilayers. It was found that such transfer proceeds via the aqueous phase and its rate-limiting step is the dissociation of retinol from the binding protein. The rate of transfer therefore represents the rate of dissociation. The kd was 0.112 min-1. These values were validated further by the following consideration. The equilibrium dissociation constant of RBP and retinol can be calculated from the expression Kd = kd/ka. The calculated value was 7.5 X 10(-8) M. Kd was also measured directly by fluorometric titration and was found to be 7 X 10(-8) M. The relative avidities of retinol for RBP, the complex RBP-transthyretin (RBP-TTR), and serum albumin were also studied. It was found that binding of RBP to TTR increased its avidity for retinol by about 2-fold. The avidity of albumin for retinol was 30-fold lower than that of RBP. The data imply that retinol spontaneously and rapidly dissociates from sites on binding proteins, which indicates that the vitamin can freely move in vivo between physiologic compartments with avidities for it.
The application of pattern recognition techniques to ESM data processing (1988)

The application of pattern recognition techniques to ESM data processing has been studied, with particular reference to pulse-by-pulse analysis using intra-pulse parameters alone. Many current pulse deinterleaving methods are based on batch processing using time-of-arrival-difference (TOAD) analysis, which is both computationally expensive (especially in highly dense environments) and unreliable in certain scenarios (for example in the presence of agile emitters). The use of pattern recognition techniques has been suggested as an alternative approach to the deinterleaving of pulse data which would allow continuous (rather than batch) analysis on a pulse-by-pulse basis based on intra-pulse parameters alone (replacing TOAD analysis). This paper presents the conclusions of this study, and makes some recommendations for future work. >
Automated generation of TTCN-3 test scripts for SIP-based calls (2010)

The complexity of modern telecommunications systems implies the need for thorough and systematic software testing. Software testing is an expensive and time-consuming task involving specification of what and how to test, and preparation of test descriptions in a format that is accepted by the test equipment. To cut down the cost of manual testing and to increase its reliability, steps may be taken to automate the whole test case preparation process. The Testing and Test Control Notation Version 3 (TTCN-3) is an internationally standardized language for defining test specifications for a wide range of computer and telecommunication systems. It allows the concise description of test behavior by unambiguously defining the meaning of a test case pass or fail. In this paper, we describe a model for automatic test generation, and describe an implemented solution for automatic generation of TTCN-3 test scripts based on parsing SIP call traces. The implemented solution is tested using TITAN, a TTCN-3 test execution environment developed in Ericsson.
College students and sexual dynamics: Two studies of peer sexual harassment (1996)

Research into the problem of sexual harassment has tended to focus on harassment that occurs within overt power relationships, e.g., bosses and employees, teachers and students, doctors and patients, lawyers and clients. However, sexual harassment that occurs between peers‐persons whose relationship is not based on an overt power or status differential‐can be devastating. In this paper, we report the results of two university studies conducted to more fully understand the problem of peer sexual harassment. Of specific interest in Study 1 are the numbers of female and male students who had been victims/targets of peer sexual harassment, along with information regarding their relationship to their harassers, the settings in which harassment occurred, and the verbal and nonverbal behaviors communicated. Study 2 was designed to access students' views as to what behaviors constituted sexual harassment, as well as to examine differences in men's and women's judgments regarding the severity of each behavior. As expected, the numbers of respondents who had been targets of peer sexual harassment varied by sex. Sex differences also emerged regarding the severity of harassing behaviors, with a general trend for women to view certain behaviors as harassing and as more severe than men. Classmates were a primary category of harassers for women and a secondary category for men. Classrooms emerged among a variety of settings within which peer harassment is likely to occur. The presence of peer sexual harassment in college classrooms is documented and implications for classroom instructors and teaching assistants are provided.
An Efficient Graph Codec System for Software Watermarking (2012)

In this paper we propose an efficient and easily implemented codec system for encoding watermark numbers as reducible permutation flow-graphs. More precisely, in light of our recent encoding algorithms which encode a watermark value w as a self-inverting permutation π*, we present an efficient algorithm which encodes a self-inverting permutation π* as a reducible permutation flow-graph F[π*] by exploiting domination relations on the elements of π* and using an efficient DAG representation of π*. The whole encoding process takes O(n) time and space, where n is the binary size of the number w or, equivalently, the number of elements of the permutation π*. We also propose efficient decoding algorithms which extract the permutation π* from the reducible permutation flow-graph F[π*] within the same time and space complexity. The two main components of our proposed codec system, i.e., the self-inverting permutation π* and the reducible permutation graph F[π*], incorporate important structural properties which make our codec system resilient to attacks.
Enabling Cleaner Fuels: Desulfurization by Adsorption to Microporous Coordination Polymers (2009)

Microporous coordination polymers (MCPs) are demonstrated to be efficient adsorbents for the removal of the organosulfur compounds dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (DMDBT) from model diesel fuel and diesel fuel. For example, packed bed breakthrough experiments utilizing UMCM-150 find capacities of 25.1 g S/kg MCP for DBT and 24.3 g S/kg MCP for DMDBT from authentic diesel indicating that large amounts of fuel are desulfurized before the breakthrough point. Unlike activated carbons, where selectivity has been a problem, MCPs selectively adsorb the organosulfur compounds over other, similar components of diesel. Complete regeneration using toluene at modest temperatures is achieved. The attainment of high selectivities and capacities, particularly for the adsorption of the refractory compounds that are difficult to remove using current desulfurization techniques, in a reversible sorbent indicates that fuel desulfurization may be an important application for MCPs.
Analysis of quadrifilar resonant printed helical antenna for mobile communications (1993)

On the basis of a modified form of Meis integral equation, which includes dielectric effects using the quasistatic approximation theory proposed by Popovic, the input impedance and the radiation patterns of several quadrifilar helical antennas with axial or normal mode are investigated. The theoretical results agree quite well with experiment.
Volatile organic compounds discriminate between eosinophilic and neutrophilic inflammation<i>in vitro</i> (2016)

Inflammation associated oxidative stress leads to peroxidation of polyunsaturated fatty acids thereby generating volatile organic compounds (VOCs). The integrative analysis of the total amount of VOCs released by eosinophils and neutrophils in vitro enables the search for those compounds that discriminates between various inflammatory conditions. The approach comprises isolating eosinophils and neutrophils from 30 ml of blood of healthy non-smoking volunteers by gradient centrifugation, using lymphoprep. Eosinophils are separated from neutrophils by immunomagnetic cell separation using anti-CD16. Cells are activated with phorbol 12-myristate 13-acetate and VOCs from the headspace are collected at time 0', 30', 60' and 90' by introduction of ultra-pure nitrogen in the closed flasks at a flow rate of 200 ml min(-1) during 10 min. The gases are trapped onto a sorption tube and analyzed by gas chromatography-time-of-flight-mass spectometry (GC-TOF-MS) in order to identify VOCs released in the headspace by activated neutrophils and eosinophils. Eosinophils and neutrophils were isolated from 26 healthy non-smoking volunteers. The average absolute number of eosinophils and neutrophils upon isolation was 3.5 × 10(6) and 19.4 × 10(6), respectively. The volatome in headspace consisted of 2116 compounds and those compounds present in at least 8% of the samples (1123 compounds) were used for further discriminant analysis. Discriminant analysis showed that two VOCs were able to distinguish between eosinophilic and neutrophilic cultures in the unactivated state with 100% correct classification of the entire data set and upon cross validation while five VOCs were able to discriminate between activated eosinophils and neutrophils with 96% correct classification in the original set and upon cross-validation. Analysis of VOCs seems to be a very promising approach in identifying eosinophilic and neutrophilic inflammation but it needs further development and in vivo confirmation.
1400-1900 GHz local oscillators for the Herschel Space Observatory (2003)

3PL continues to develop robust planar, all solid-state sources to cover the 1414 to 1908 GHz band. These sources will be used as local oscillators to drive hot electron bolometer (HEB) heterodyne mixers on the Herschel Space Observatory to observe high-resolution spectra in the interstellar medium such as the N+ and C+ fine structure lines at 1461 and 1901 GHz, water
VISIBLE CW PARAMETRIC OSCILLATOR (1968)

A tunable optical parametric oscillator using a 5145-Å argon laser as a pump and lithium niobate as the nonlinear material is reported. The oscillator is constructed in a manner such that the total multimode power of the pumping laser is useful for pumping the oscillator. Operation far from degenerate, combined with a relatively long crystal, leads to measured bandwidths of oscillation about ten times less than those previously reported.

Guide RNA Requirement for Editing-Site-Specific Endonucleolytic Cleavage of Preedited mRNA by Mitochondrial Ribonucleoprotein Particles in <i>Trypanosoma brucei</i> (1997)

RNA editing in trypanosome mitochondria entails the posttranscriptional internal addition and occasional deletion of uridines from precursor mRNAs. Ample evidence exists to show that the information specifying the site and number of uridines added or deleted comes from small, mitochondrially encoded guide RNAs (gRNAs). More recent work indicates that the process involves an enzymatic cascade, initiating with an endonucleolytic cleavage of the pre-mRNA at an editing site. The cleaved editing site can undergo uridine (U) addition to or deletion from the 3' end of the 5' fragment via a mitochondrial terminal uridylyl transferase (TUTase) or terminal uridylyl exonuclease, respectively. Mitochondrial RNA ligase subsequently rejoins the mRNA. Activities to carry out these processes have been found in trypanosome mitochondria, including an editing-site-specific endonuclease activity which cleaves preedited but not edited mRNAs. We have found that this enzymatic activity cosediments with the same 19S ribonucleoprotein particle previously shown to contain TUTase, RNA ligase, and gRNAs and remains stable after salt treatment. Depletion of endogenous cytochrome b gRNAs by the addition of complementary oligonucleotides in vitro completely inhibits editing-site cleavage of synthetic preedited cytochrome b mRNA. The addition of synthetic cognate gRNA for cytochrome b but not unrelated small RNA restores editing-site cleavage. These studies show that in addition to specifying the site and number of uridines added or deleted, gRNAs provide the necessary information for cleavage by the editing-site-specific endonuclease.
Wafer-scale laser pantography. 2: Laser-induced pyroiytic creation of MOS structures (1983)

This paper reports on means for generating micron-scale structures of metal, doped silicon, and polysilicon suitable for implementing a metal- oxide-semiconductor (MOS) technology in ultra-large-scale integrated (ULSI) circuits. The approach involves use of a laser to induce local decomposition of metal-containing compounds during the metal deposition portion of the process, dopant-containing compounds during the doping phase of the process, and silane during the polysilicon formation phase of the process.
Improved cedervall‐Johannesson algorithm for computing the distance spectrum of convolutional codes (1996)

Abstract In the convolutional code, the minimum free distance is the important parameter to evaluate the performance of the code. Recently, it has been considered necessary, however, for a more strict evaluation of the performance to examine the number of code words with weights around the minimum free distance, i.e., the more general distance spectrum. In general, it is difficult to derive the distance spectrum of a code, including the derivation of the minimum free distance when the code size is enalrged, and it will be significant if it is derived easily. This paper proposes an algorithm that can derive the distance spectrum with a high speed, compared to the method already proposed. The algorithm presented in this paper is an improvement of the fast algorithm for searching trees (FAST) proposed by M. Cedervall and R. Johannesson. The distance spectrum can be derived with approximately one‐half the computational complexity compared to FAST.
ISIS: A Constraint-Directed Reasoning Approach to Job Shop Scheduling. (1983)

Analysis of the j(b shop scheduling domain has indicated that de crux of the scheduling problem is the determination and satisfaction of a large number and variety of constraints. Schedules arc influenced by such diverse factors as due date requirements, cost restrictions, production levels, machine capabilities, operation precedences. resource requirements, and resource availability. This paper describes 1SIS, a scheduling system capable of incorporating all relevant constraints in the construction of job shop schedules. We examine both the representation of&apos; constraints within ISIS, and the: manter in &apos;hich these cor, straints are utilized in conducting a constraint-directed search for an acceptable schedule. The importat issues relating to the relaxation of constraints are addressed. Finally, the interactive scheduling facilities provided by ISIS are considered. 1. introduc,ion Tio constructi(&gt;n of schedules to cjovern the production of orders in a job shop is a complex problem that is influenced by knowledge accumulated from many different sources in the shop. The acceptcbdity of a particular schedule depends on such diverse factors as due date requirements, cost restrictions, production levels, machine capabilities, operation precedences, resource requirements, and resource availability. Most current approaches to automatic scheduling incorporate only a fraction of this knowledge. This leads to a purely predictive o. pproach to scheduling; based on a restricted model of the environment, predictions are made as to when operations are to be performed.

Nerve growth factor ( <scp>NGF</scp> ): a potential urinary biomarker for overactive bladder syndrome ( <scp>OAB</scp> )? (2013)

Whilst the evidence for an increased urinary NGF in OAB appears convincing, many questions about its validity remain including: specificity, sensitivity, cost- and time-effectiveness. Many criteria for what constitutes a biomarker still need to be evaluated and met before this molecule can be considered for this role.
Oceanic Uptake of Fossil Fuel CO <sub>2</sub> : Carbon-13 Evidence (1992)

The delta(13)C value of the dissolved inorganic carbon in the surface waters of the Pacific Ocean has decreased by about 0.4 per mil between 1970 and 1990. This decrease has resulted from the uptake of atmospheric CO(2) derived from fossil fuel combustion and deforestation. The net amounts of CO(2) taken up by the oceans and released from the biosphere between 1970 and 1990 have been determined from the changes in three measured values: the concentration of atmospheric CO(2), the delta(13)C of atmospheric CO(2) and the delta(13)C value of dissolved inorganic carbon in the ocean. The calculated average net oceanic CO(2) uptake is 2.1 gigatons of carbon per year. This amount implies that the ocean is the dominant net sink for anthropogenically produced CO(2) and that there has been no significant net CO(2) released from the biosphere during the last 20 years.
