Two-tone vs. random process inputs for nonlinear distortion estimation (1992)

Two methods (two-tone input approach and random process input approach) for the estimation of harmonic and intermodulation distortion of nonlinear systems are compared. The random input approach, where a nonlinear system is modeled by a second-order Volterra series, is examined in terms of its statistical properties, and its advantages and limitations over the classical two-tone input approach. Experimental results are shown where these two approaches are applied to evaluate second-order distortion of a loudspeaker and to compare the performance of these approaches in terms of Volterra kernels and distortion factors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Dynamic sealing principles (1976)

The fundamental principles governing dynamic sealing operation are discussed. Different seals are described in terms of these principles. Despite the large variety of detailed construction, there appear to be some basic principles, or combinations of basic principles, by which all seals function, these are presented and discussed. Theoretical and practical considerations in the application of these principles are discussed. Advantages, disadvantages, limitations, and application examples of various conventional and special seals are presented. Fundamental equations governing liquid and gas flows in thin film seals, which enable leakage calculations to be made, are also presented. Concept of flow functions, application of Reynolds lubrication equation, and nonlubrication equation flow, friction and wear; and seal lubrication regimes are explained.
Sample processing obscures cancer-specific alterations in leukemic transcriptomes (2014)

Substantial effort is currently devoted to identifying cancer-associated alterations using genomics. Here, we show that standard blood collection procedures rapidly change the transcriptional and posttranscriptional landscapes of hematopoietic cells, resulting in biased activation of specific biological pathways; up-regulation of pseudogenes, antisense RNAs, and unannotated coding isoforms; and RNA surveillance inhibition. Affected genes include common mutational targets and thousands of other genes participating in processes such as chromatin modification, RNA splicing, T- and B-cell activation, and NF-κB signaling. The majority of published leukemic transcriptomes exhibit signals of this incubation-induced dysregulation, explaining up to 40% of differences in gene expression and alternative splicing between leukemias and reference normal transcriptomes. The effects of sample processing are particularly evident in pan-cancer analyses. We provide biomarkers that detect prolonged incubation of individual samples and show that keeping blood on ice markedly reduces changes to the transcriptome. In addition to highlighting the potentially confounding effects of technical artifacts in cancer genomics data, our study emphasizes the need to survey the diversity of normal as well as neoplastic cells when characterizing tumors.
The SOC framework and short-term memory (2002)

Using a particular formula for quantifying the effortlessness that Perruchet & Vinter suggest accompanies the detection of repetition among a set of representations concurrently in consciousness, it is shown that both the Sternberg function and the Cavanagh function, associated with immediate probed recognition tasks and memory span tasks, can be predicted.
Characterization of silicon crystals grown by the heat exchanger method (1983)

Silicon ingots grown by the Heat Exchanger Method (HEM) as large as 45 kg in mass (34 cm x 34 cm x 17 cm) are characterized electrically and structurally. The defect state in the crystal is related to the solar cell efficiency. Such characterization indicates that the solar cell efficiency of HEM crystals is limited by the crystal perfection, but that HEM silicon has the potential to yield silicon with quality comparable to Cz grown silicon. A new approach to grow HEM material of better quality is discussed.
Towards a flexible and contextually appropriate generation of spoken utterances (2002)

Current vocal output generation systems lack portability and variability. Text-to-speech synthesis is not well accepted by users for its lack of conviviality. We propose alternative approaches to generating spoken utterances that fulfill the quality requirements of a speech output system. Our framework for language generation relies on conceptual segments, we controlled their acoustic realization by means of four basic methods based on four levels of representation: signal concatenation, text-to-speech, mimicking synthesis and phonological prosodic command driving the speech synthesizer. Examples produced allow a step towards flexible and contextually appropriate generation of spoken utterances.
Involvement of Water in Carbohydrate−Protein Binding (2001)

The interactions of trimannosides 1 and 2 with Con A were studied to reveal the effects of displacement of well-ordered water molecules on the thermodynamic parameters of protein-ligand complexation. Trisaccharide 2 is a derivative of 1, in which the hydroxyl at C-2 of the central mannose unit is replaced by a hydroxyethyl moiety. Upon binding, this moiety displaces a conserved water molecule present in the Con A binding site. Structural studies by NMR spectroscopy and MD simulations showed that the two compounds have very similar solution conformational properties. MD simulations of the complexes of Con A with 1 and 2 demonstrated that the hydroxyethyl side chain of 2 can establish the same hydrogen bonds in a low energy conformation with the protein binding site as those mediated by the water molecule in the complex of 1 with Con A. Isothermal titration microcalorimetry (ITC) measurements showed that 2 has a more favorable entropy of binding compared to 1. This term, which was expected, arises from the return of the highly ordered water molecule to bulk solution. The favorable entropy term was, however, offset by a relatively large unfavorable enthalpy term. This observation was rationalized by comparing the extent of hydrogen bond and solvation changes during binding. It is proposed that an indirect interaction through a water molecule will provide a larger number of hydrogen bonds in the complex that have higher occupancies than in bulk solution, thereby stabilizing the complex.
Cathodic arc ion implantation for semiconductor devices (1995)

Cathodic arc ion implantation was used to make n+–p junction diodes and n-channel metal–oxide–semiconductor (MOS) transistors. Antimony, with a dosage in the range of 6×1014 to 4×1015 ions/cm2, was implanted as the n-type dopant into p-type 〈100〉 oriented silicon with a resistivity in the range of 2–5 Ω cm. The implantation voltage applied to the substrate was approximately −20 kV. Regular thermal oxidation and photolithography techniques were used in making the devices. The I–V characteristics of both diodes and transistors and the reverse breakdown of the n+–p junction were found to be comparable to the devices made by diffusion under similar conditions. The standard deviation of the sheet resistance of the implanted layer across a 3 in. wafer was found to be less than 4% of the average value. The implantation dosage and distribution characteristics were estimated by secondary ion mass spectrometry (SIMS) and Rutherford backscattering spectrometry (RBS) measurements. The experimental results were found to agree with numerically calculated values. The ion charge state of the arc plasma was extracted by comparing the experimental results and numerical results.
The Multiple-Choice Knapsack Problem (1979)

The multiple-choice knapsack problem is defined as a binary knapsack problem with the addition of disjoint multiple-choice constraints. The strength of the branch-and-bound algorithm we present for this problem resides with the quick solution of the linear programming relaxation and its efficient, subsequent reoptimization as a result of branching. An implemented version of this algorithm has performed well on a large set of test problems. We cite computational results as well as a comparison with a previously reported algorithm. Several useful applications of the multiple-choice knapsack problem are also suggested.
Animal Models for Nervous System Disease in Systemic Lupus Erythematosus (1997)

Animal models have much to teach us about nervous system dysfunction in SLE. It should be stressed that the murine strains described in this review have variable expression in the onset and severity of clinical and serological features, perhaps making them more like a heterogeneous human population with SLE. With this in mind, studies involving animal models like those involving human subjects should use a sample size that ensures adequate power. It is not surprising that studies that use sample sizes as low as four to five animals per group would find discrepant results, especially in outcomes that are measured prior to the terminal phases of the disease. Similar to human SLE patients, murine models have systemic autoimmune as well as neurological manifestations. Studies with murine models must continue to consider some type of SLE disease activity measures in order to control for the effects of systemic disease on nervous system dysfunction. Because of the short time window between the earliest evidence of neurologic dysfunction and severe autoimmune disease manifestations, especially in MRL/lpr mice, the disease acceleration model may allow a more careful dissection of how immunological events are related to nervous system dysfunction. Alternatively, the study of MRL/lpr mice ultraearly (e.g., 3 weeks of age) could also provide invaluable information about the first events leading to nervous system dysfunction in SLE. Both approaches promise to identify predictors of specific nervous system manifestations that may suggest novel and more specific therapeutic interventions.
A Dark Tale Behind Two Retractions (2009)

“Meet the Expert Interviews,” an Integrative Learning Experience for Microbiology and Anatomy & Physiology Undergraduate Students (2014)

An important goal of higher education is to encourage students to integrate learning and apply skills to different situations. In the “Meet the Expert Interviews” students interviewed authors of research papers on Shiga Toxin Producing E. coli (STEC) outbreaks. Students attended seminars, analyzed STEC publications, created questions, and interviewed authors. We hypothesized that the project would enhance student understanding of STEC and encourage students to integrate and apply information to real world problems. The project was assessed by student surveys. The majority of 129 students surveyed agreed or strongly agreed that the seminar enhanced their understanding of E.coli transmission, diagnosis, and treatment; that the interview enhanced their understanding of epidemiology; and made them more aware of the steps involved in determining the cause of the outbreak. The project was engaging for students and faculty and provided a unique way for professional outreach to biology students. The project is an innovative example of an integrative method to enhance student learning and interaction with microbiology and epidemiology professionals.
Extracorporeal Circulation: A Device for the Quantitative Study of Thrombus Formation in Flowing Blood (1963)

A standardized extracorporeal shunt system has been described. It allows examination of the sequence of events in thrombus formation and it provides a means of quantitating it in flowing blood. It further allows assessment to be made of the usefulness of classical in vitro clotting tests in thrombogenesis. The platelet adhesive index and clotting time in silicone showed the best correlation with the amount of thrombus formed. Pig serum presumably rich in serum thrombotic accelerator (STA) has been shown to enhance thrombus formation from flowing blood. Within the limits of these experiments, the rate of blood flow has been found to be of little importance.

Advanced technology for functionalization of carbon nanotubes (2009)

Functionalization of carbon nanotubes (CNTs) has attracted considerable interest in the fields of physics, chemistry, material science and biology. The functionalized CNTs exhibit improved properties enabling facile fabrication of novel nanomaterials and nanodevices. Most of the functionalization approaches developed at present could be categorized into the covalent attachment of functional groups and the non-covalent adsorption of various functional molecules onto the surface of CNTs. This review highlights recent development and our work in functionalization of carbon nanotubes, leading to bio-compatible CNTs, fluorescent CNTs and transition metal functionalized CNTs. These novel methods possess advantages such as simplified technical procedures and reduced cost of novel nanomaterials and nanodevices fabrication.

An Augmented Reality System for the Treatment of Acrophobia: The Sense of Presence Using Immersive Photography (2006)

This paper describes an augmented reality (AR) system for the treatment of acrophobia. First, the technical characteristics of the original prototype are described. Second, the capacity of the immersive photography used in the AR system to provoke sense of presence in users is tested. Forty-one participants without fear of heights walked around a staircase in both a real environment and an immersive photography environment. Immediately after their experience, participants were given the SUS questionnaire to assess their subjective sense of presence. The users' scores in the immersive photography were very high. Results indicate that the acrophobic context can be useful for the treatment of acrophobia. However, statistically significant differences were found between real and immersive photography environments. Specifically, the immersive photography environment was not confused with reality since data showed that SUS distinguished between the real and immersive photography experiences.

LXXXVII. Theory of dislocations in germanium (1954)

Abstract Dislocations have a large effect on the electrical properties of germanium. Experiments show that dislocations act as acceptor centres. This paper discusses a simple model (due to W. Shockley) which identifies dislocation acceptors with the dangling unpaired electrons on the edge of the extra atomic plane of a dislocation having some edge component. In n-type germanium the line of acceptors along a dislocation accepts electrons and becomes negatively charged. The electrostatic energy in the resulting space charge region is found and shown to be a dominant factor in determining the occupation of dislocation acceptors. Formulas are given for the temperature variation of the average electron concentration in n-type material that has been lightly deformed by plastic bending. Experiments are suggested to test the theory and determine exactly the energy level of the dislocation acceptors.

Relationship between MODIS-NDVI data and wheat yield: A case study in Northern Buenos Aires province, Argentina (2015)

In countries like Argentina, whose economy depends heavily on crop production, the estimation of harvests is an elementary requirement. Besides providing objectivity, the use of remote sensing allows estimating yield in advance. Since the time of maximum leaf area in wheat corresponds with the critical period of the crop, a good relationship is expected between the Normalized Difference Vegetation Index (NDVI) and yield. The present study was carried out in the North of Buenos Aires province, Argentina. Based on the type of soil, the study area can be divided into two homogeneous subzones: a subzone with lower clay content in the southwest and a subzone with higher clay content in the northeast. Nine growing seasons (2003–2011) were studied. In the first five years, an empirical model was calibrated and validated with field-observed wheat yields and MOD13q1 product-NDVI data, whereas in the other four years, the calibrated model was applied by means of yield maps and by comparing with official yields. The MOD13q1 image corresponding to Julian day 289 showed the best fit between NDVI and yield to estimate wheat yield early. Through yield maps, better weather conditions showed higher yields and higher soil productivity presented a greater proportion of the area occupied by higher yields. At department level, an R2 value of 0.75 was found after relating the estimation of the calibrated empirical model with official yields. The method used allows predicting wheat yield 30 days before harvest. Through yield maps, the NDVI perceived the temporal and spatial variability in the study area.
Fine-Grained and Scalable Approaches for Message Integrity (2007)

When we have multiple users compiling a single message, including shared contents, metadata, policy, and so on, the integrity of the contents created by individual users needs to be maintained in an effective manner. There is an urgent need for new mechanisms in a trusted content-sharing environment to support multiple signers for the same message, which can be dynamically updated with autonomous protection and maintenance mechanisms. In our previous work we identified and compared three different binding mechanisms including monolithic, autonomous, and chained binding mechanisms, using digital signatures. The original work was designed and implemented for digital certificates. In this paper we apply those schemes with extension to the organization-to-organization messaging services that require effective integrity verification and tracking mechanisms at the user-level in the receiving organization in a scalable manner with fine granularity. We implement our ideas in the Java remote method invocation (RMI) platform and discuss the trade-offs of the signature schemes based on our experimental results

Identification of novel candidate target genes in amplicons of Glioblastoma multiforme tumors detected by expression and CGH microarray profiling (2006)

This high-resolution analysis allowed us to propose novel candidate target genes such as STIM2 at 4p15, and TNFSF13B or COL4A2 at 13q32-34 that could potentially contribute to the pathogenesis of these tumors and which would require futher investigations. We showed that overexpression of the amplified genes could be attributable to gene dosage and speculate that deregulation of those genes could be important in the development and progression of GBM. Our findings highlight the important influence in GBM of signaling pathways such as the PI3K/AKT, consistent with the invasive features of this tumor.
The Lived Meanings of Chinese Social Network Sites (SNSs) among Urban White-Collar Professionals (2010)

A phenomenological study reveals the lived meanings of Chinese social network sites (SNSs) among urban, white-collar professional users through an investigation of a newly launched SNS, Happy Network. Their shared meanings of the Happy Network were interdependent with participants’ interpretations of time, fun, need to belong, and social interactions, shaped by and reflective of their social role as white-collar professionals and the cultural characteristics of contemporary Chinese society. Specifically, participants’ understandings of the Happy Network entailed five dialectic relations: in control/controlled by, dependent/independent, public/private, intimate/distant, and personal/social.
