Real-time Phase Vocoder Manipulation by Runner's Pace (2009)

This paper presents a method for using a runner’s pace for real-time control of the time-scaling facility of a phase vocoder, resulting in the automated synchronization of an audio track tempo to the generated control signal. The increase in usage of portable music players during exercise has given rise to the development of new personal exercise aids, most notably the Nike+iPod system, which relies on embedded sensor technologies to provide kinematic workout statistics. There are also systems that select songs based on the measured step frequency of a runner. The proposed system also uses the pace of a runner, but this information is used to change the tempo of the music.
Ruthenium polypyridyl complexes and their modes of interaction with DNA: Is there a correlation between these interactions and the antitumor activity of the compounds? (2008)

Various interaction modes between a group of six ruthenium polypyridyl complexes and DNA have been studied using a number of spectroscopic techniques. Five mononuclear species were selected with formula [Ru(tpy)L(1)L(2)]((2-n)+), and one closely related dinuclear cation of formula [{Ru(apy)(tpy)}(2){mu-H(2)N(CH(2))(6)NH(2)}](4+). The ligand tpy is 2,2':6',2''-terpyridine and the ligand L(1) is a bidentate ligand, namely, apy (2,2'-azobispyridine), 2-phenylazopyridine, or 2-phenylpyridinylmethylene amine. The ligand L(2) is a labile monodentate ligand, being Cl(-), H(2)O, or CH(3)CN. All six species containing a labile L(2) were found to be able to coordinate to the DNA model base 9-ethylguanine by (1)H NMR and mass spectrometry. The dinuclear cationic species, which has no positions available for coordination to a DNA base, was studied for comparison purposes. The interactions between a selection of four representative complexes and calf-thymus DNA were studied by circular and linear dichroism. To explore a possible relation between DNA-binding ability and toxicity, all compounds were screened for anticancer activity in a variety of cancer cell lines, showing in some cases an activity which is comparable to that of cisplatin. Comparison of the details of the compound structures, their DNA binding, and their toxicity allows the exploration of structure-activity relationships that might be used to guide optimization of the activity of agents of this class of compounds.
Yield management methodology for SoC vertical yield ramp (2002)

This paper proposes a new yield management method for the SoC (System on a Chip) VYR (vertical yield ramp). In this method, test structures and analysis methods are adjusted to quantitatively analyze and optimize failure modes for improved yield. To verify the new methodology, two types of test chips were designed to monitor and distinguish the various failure modes affecting typical LSI product chips. It is concluded that the new methodology can diagnose and improve these several failure modes simultaneously to achieve the SoC VYR.
A study of inter-lab and inter-platform agreement of DNA microarray data (2005)

As gene expression profile data from DNA microarrays accumulate rapidly, there is a natural need to compare data across labs and platforms. Comparisons of microarray data can be quite challenging due to data complexity and variability. Different labs may adopt different technology platforms. One may ask about the degree of agreement we can expect from different labs and different platforms. To address this question, we conducted a study of inter-lab and inter-platform agreement of microarray data across three platforms and three labs. The statistical measures of consistency and agreement used in this paper are the Pearson correlation, intraclass correlation, kappa coefficients, and a measure of intra-transcript correlation. The three platforms used in the present paper were Affymetrix GeneChip, custom cDNA arrays, and custom oligo arrays. Using the within-platform variability as a benchmark, we found that these technology platforms exhibited an acceptable level of agreement, but the agreement between two technologies within the same lab was greater than that between two labs using the same technology. The consistency of replicates in each experiment varies from lab to lab. When there is high consistency among replicates, different technologies show good agreement within and across labs using the same RNA samples. On the other hand, the lab effect, especially when confounded with the RNA sample effect, plays a bigger role than the platform effect on data agreement.
Computer mediated communication: A window on L2 Spanish interlanguage (2000)

The Interaction Hypothesis states that the conditions for SLA are crucially enhanced by having L2 learners negotiate meaning (i.e., resolve their miscommunications) with other speakers, native or otherwise (Long & Robinson, 1998, p. 22).This study demonstrates that incidental negotiations commonly occurred in networked learner/learner discussions as well, especially with respect to their lexical confusions.Fifty intermediate L2 Spanish learners were asked to carry out networked discussions in pairs during their lab time using a synchronous chat program, Remote Technical Assistance (RTA), which records all textual entries.Each dyad carried out a series of online tasks that can be described as jigsaw, information-gap, or decision-making.The results show that jigsaw tasks appear to lead the way in promoting negotiations, as Pica, Kanagy, and Falodun (1993) had previously predicated, but that information-gap tasks were not nearly as productive as a stimulus.The findings suggest that computer mediated communication (CMC) can provide many of the alleged benefits ascribed to the Interaction Hypothesis, but with greatly increased possibilities for access outside of the classroom environment.Nevertheless, the predominance of incidental lexical negotiations, in contrast to the paucity of syntactic negotiations, leaves unanswered or unsatisfactorily addressed the issue of grammatical development.The study demonstrates, however, the value of synchronous chat records as a window for investigating interlanguage.
2-Fluoroformycin and 2-aminoformycin. Synthesis and biological activity (1985)

Syntheses of 2-fluoroformycin [7-amino-5-fluoro-3-(beta-D-ribofuranosyl)pyrazolo[4,3-d]pyrimidine] (2b) and 2-aminoformycin [5,7-diamino-3-(beta-D-ribofuranosyl)pyrazolo[4,3-d]pyrimidine] (2c) are described. Cytotoxicity data are given for 2b and 2c alone as well as with added pentostatin. Kinetic parameters for adenosine deaminase are also provided. 2-Fluoroformycin, although a much poorer substrate for adenosine deaminase than formycin A, is not nearly as cytotoxic to cells in culture.
Immunologic Response of Turkeys to an Avirulent Pasteurella multocida Vaccine in the Drinking Water. (1972)

Turkeys were injected with a commercial oil base bacterin (containing P-1059, P,1662, and X-73 strains) at 8 weeks of age. An avirulent Pasteurella multocida P-1059 strain was administered in the drinking water at 12 weeks of age. At 21 weeks of age, separate groups of vaccinated and nonvaccinated turkeys were exposed to either a P-1059, a P-1662, or an X-73 virulent strain. This procedure was repeated at 28 weeks and again at 42 weeks of age. Under the conditions of the 3 experiments conducted, the total number infected was 1 of 30 turkeys, 1 of 30 turkeys, and 7 of 30 turkeys at 9, 16, and 30 weeks postvaccination, respectively. In the nonvaccinated groups, the total number infected was 29 of 30 turkeys, 29 of 30 turkeys, and 19 of 21 turkeys, respectively. These results suggest (1) that an avirulent vaccine used 4 weeks after the use of an oil base bacterin was effective in reducing the total number infected at 9, at 16, and at 30 weeks postvaccination, but (2) that at 30 weeks postvaccination, the reduction of the total number infected was not as great. (3) The duration of the immunity to the virulent homologous (P-1059) strain appeared to be similar to the duration of the immunity to each of the two virulent heterologous (P-1662 and X-73) strains.
Hexagonal YMnO<sub>3</sub> (2001)

The crystal structure of hexagonal yttrium trioxomanganate has been determined at room temperature and at 180 K. It is isomorphous with LuMnO(3). The Mn displacement vector has a frustrated component in the ab plane and a ferroelectric part along the c axis. The net ferroelectricity is zero due to inversion twinning, with 1:1 twin fractions.
Galileo Orbit Selection (2004)

The Galileo Constellation will consist of 30 satellites in three orbit planes, with 27 operational spacecraft and three in-orbit spares. The nine operational spacecraft in each orbit plane will be equally spaced along the orbit, forming a 27/3/1 Walker constellation. During Phase B of the Galileo project, two different orbit altitudes have been used in system studies, leading to a three-day ground track repeat orbit on the one hand and a ten day repeat orbit on the other. In the C0 phase, which is now nearing completion, the final orbit parameters had to be defined. Availability analyses had already led to the selection of the mean orbit inclination of 56 degrees. This paper presents the final choice for the semi-major axis of the Galileo orbits. Several different criteria play a role in this choice. A short repeat period is advantageous for In-Orbit Validation (IOV) and commissioning, as each satellite returns more frequently to the same position over the Earth’s surface, but leads to undesirable orbit perturbations due to resonance phenomena, which will require correction by means of maintenance manoeuvres. There is a strong desire to minimise the number of these manoeuvres, which require the satellite to be taken out of service while the orbit is adjusted. It is important to use identical orbit parameters in IOV and the Full Operational Configuration (FOC), as IOV satellites will continue in service through to FOC and would otherwise need to be moved. The paper also analyses two alternative types of orbits, and concludes by presenting the best alternative available, the orbit finally selected for the Galileo constellation, by joint decision of the European Space Agency and the Galileo industrial consortium. It has a 10-day repeat cycle, with 17 revolutions in close to ten sidereal days, and a mean semi-major axis of about 29600 km. The paper finally briefly addresses the requirements on orbit injection accuracy and long-term orbit prediction accuracy, which are pre-requisites for a long-term operation of the constellation without the need for frequent maintenance manoeuvres.
The <i>WIGGUM</i> gene is required for proper regulation of floral meristem size in <i>Arabidopsis</i> (1998)

The study of cell division control within developing tissues is central to understanding the processes of pattern formation. The floral meristem of angiosperms gives rise to floral organs in a particular number and pattern. Despite its critical role, little is known about how cell division is controlled in the floral meristem, and few genes involved have been identified. We describe the phenotypic effects of mutations in WIGGUM, a gene required for control of cell proliferation in the floral and apical meristem of Arabidopsis thaliana. wiggum flowers contain more organs, especially sepals and petals, than found in wild-type flowers. This organ number phenotype correlates with specific size changes in the early floral meristem, preceding organ initiation. Genetic studies suggest that WIGGUM acts on a similar process but in a separate pathway than the CLAVATA1 and CLAVATA3 genes in meristem size regulation, and reveal interactions with other genes affecting meristem structure and identity. Analysis of double mutant phenotypes also reveals a role for WIGGUM in apical meristem function. We propose that WIGGUM plays a role in restricting cell division relative to cellular differentiation in specific regions of the apical and floral meristems.
Metallopolymers with emerging applications (2008)

A wide variety of metal-containing polymers, or ‘metallopolymers’, have become readily available over the past decade. This has led to a rapidly expanding interest in their properties and uses. These new materials combine the processing advantages of polymers with the functionality provided by the presence of metal centers. We illustrate a selection of applications of metallopolymers in areas such as sensors, memory and light-emitting devices, solar cells, nanolithography, photonic crystal displays, controlled release, and catalysis.
Cortical Gamma-Aminobutyric Acid and Glutamate in Posttraumatic Stress Disorder and Their Relationships to Self-Reported Sleep Quality (2014)

Low brain gamma-aminobutyric acid (GABA) concentration in posttraumatic stress disorder (PTSD) is consistent with most findings in panic and social anxiety disorders. Low GABA associated with poor sleep quality is consistent with the hyperarousal theory of both primary insomnia and PTSD. Our data demonstrate that poor sleep quality mediates low parieto-occipital GABA in PTSD. The findings have implications for PTSD treatment approaches.
Down regulation of CD11b and CD18 expression in atherosclerotic lesion-derived macrophages. (1995)

Monocyte/macrophages play an important role in the development of atherosclerosis. Electron microscopic evidence suggests that in the early stages, lipid laden monocytes leave the lesion to reenter the circulation. This reverse monocyte traffic ceases as the lesion develops. We hypothesize that monocyte/macrophages may not be able to exit the lesion and reenter the circulation because of the reduced expression of CD11/CD18 integrins. We have compared CD11b and CD18 expression of peripheral blood monocytes from normal rabbits (NMø) to atherosclerotic lesion-derived macrophages (AthMø) by anti-CD11b and anti-CD 18 antibody staining, followed by flow cytometry and immunohistochemical staining. AthMø were isolated from aortic lesions of rabbits fed 2 per cent cholesterol diet following balloon angioplasty. AthMø were separated into two regions based on their size and granularity by flow cytometry. All macrophages stained positively with RAM 11. Our results indicated that NMø showed a strong cell surface expression of CD11b and CD18. The less granular and smaller AthMø showed little anti-CD11b or anti-CD18 antibody staining, indicating very little CD11b or CD18 antibody staining, indicating very little CD11b or CD18 expression. The more granular and larger cells showed surface expression of both CD11b and CD18. With respect to CD18, over 90 per cent of NMø expressed CD18, only 37 per cent of the large granular AthMø and less than 1 per cent of the smaller, less granular AthMø stained positive for CD18. Immunohistochemical studies revealed strong surface expression of CD11b and CD18 on normal monocytes.(ABSTRACT TRUNCATED AT 250 WORDS)
Dissociation of clathrin from coated vesicles by the uncoating ATPase. (1990)

The uncoating ATPase has been shown to dissociate clathrin from both clathrin-coated vesicles and synthetic clathrin baskets (Rothman, J. E., and Schmid, S. L. (1986) Cell 46, 5-9). In the present study, we investigated the mechanism of action of the uncoating ATPase using intact coated vesicles isolated from bovine brain. We observed an initial burst of uncoating followed by much slower steady-state uncoating. The initial burst of uncoating was essentially stoichiometric with each molecule of uncoating ATPase apparently binding to one leg of the clathrin triskelion. When the enzyme was preincubated with equimolar ADP, Pi, and ATP, rather than just ATP alone, both the initial burst and the slow steady-state uncoating were markedly inhibited, suggesting that the combination of ADP and Pi is a strong competitive inhibitor of ATP binding. However, kinetic studies suggested that ADP and Pi dissociates from the enzyme relatively rapidly unless clathrin is also bound to the enzyme. These results suggest that, after the uncoating ATPase rapidly removes a stoichiometric amount of clathrin while ATP is hydrolyzed at the active site, slow release of ADP and Pi from the resulting enzyme.clathrin.ADP.Pi complex limits the rate at which further uncoating occurs.
Synthesis of Bicyclo[3.3.1]nonanes via Manganese(III) Mediated Radical Cyclization of Olefinic β-Keto Esters (1995)

Oxidative cyclization of olefinic β-keto esters 11 and 19 with Mn(OAc)3.2H2O and Cu(OAc)2⋅H2O gave 12 and 23, respectively. These products are formed by initial cyclization to a bicyclo[3.3.1]nonane radical which abstracts a hydrogen atom from the N-ethyl substituent of a proximal amide. In the case of 19, a further cyclization of the resultant radical leads to 22 which is oxidized to 23.
First-pass measurements of regional blood flow with external detectors. (1983)

A powerful, simple model has been developed for measuring regional blood flow using first-pass tracer kinetics with external detectors such as fast positron emission tomographs (PET). Its derivation is based on the hypothesis that during the first transit of a bolus of activity through an organ there exists a period during which the tracer has not left the region of interest, so that the venous concentration of the tracer is zero. Provided that this condition is met, measurement of blood flow can be obtained in any organ with any radiotracer since there are no requirements in the derivation of the model for diffusion or extraction characteristics of the tracer. The general model has been demonstrated for a special case in the heart using intravenous bolus injections of rubidium-82 with regional positron detectors (beta probes) and validated by comparison with independently determined for by labeled microspheres over a wide range of flow values from zero to five times normal resting coronary blood flow.

TERMINOLOGY OF THE TEXTURE OF CREAM (1973)

Abstract An enquiry among experts into the use of terms to describe subjectively assessed properties of double cream (48% fat) showed that ‘body’, ‘texture’ and ‘homogeneity’ were the most important and widely used, though inadequately defined. Only ‘body’ appeared to be analogous to a rheological property; ‘texture’ and ‘homogeneity’ appeared to refer to small scale and large scale structures.
A finite element model of cell deformation during magnetic bead twisting (2002)

Magnetic twisting cytometry probes mechanical properties of an adherent cell by applying a torque to a magnetic bead that is tightly bound to the cell surface. Here we have used a three-dimensional finite element model of cell deformation to compute the relationships between the applied torque and resulting bead rotation and lateral bead translation. From the analysis, we computed two coefficients that allow the cell elastic modulus to be estimated from measurements of either bead rotation or lateral bead translation, respectively, if the degree of bead embedding and the cell height are known. Although computed strains in proximity of the bead can be large, the relationships between applied torque and bead rotation or translation remain virtually linear up to bead rotations of 15 degrees, above which geometrical nonlinearities become significant. This appreciable linear range stands in contrast to the intrinsically nonlinear force-displacement relationship that is observed when cells are indented during atomic force microscopy. Finally, these computations support the idea that adhesive forces are sufficient to keep the bead firmly attached to the cell surface throughout the range of working torques.

Hot electron cold cathode for CRTs, etc (2002)

It is pointed out that the extremely hot electrons produced by loss-free acceleration known to exist in several wide-gap semiconductors used usually for thin-film electroluminescence can easily be made to exit into vacuum. The pulsed, matrix-addressable, large-area cold cathode has properties attractive for various applications. The working principle of this hot electron cold cathode (HECC) is described, and experimental results are presented. It is pointed out that one of the most interesting applications of the HECC is the flat cathode ray tube, which could consist of a usual video screen and an HECC, situated in a vacuum vessel, facing each other and realizing a 1:1 correspondence of HECC structure to screen structure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Invited Paper Fundamental Limit Of The Speed Of Photorefractive Effect (1988)

This paper deals with the fundamental limit of speed of the photorefractive effect at a given power level. Such a limit is derived by counting the number of photons needed for the formation of a photorefractive index grating.
