Pulse ranging radiolocation technique and its application to channel assignment in digital cellular radio (2002)

A sophisticated simulation package for automatic vehicle monitoring (AVM) systems using a pulse ranging technique has been developed. Using a multipath propagation database, location-error statistics have been obtained for mobile units operating in areas with various degrees of urbanization. The effect of the number and relative position of sensors on location-error statistics has been studied in detail. The performance of various linear and nonlinear optimization techniques has been tested by computer simulation. Application of the package to locating vehicles and portables in digital cellular radiotelephone systems for the purpose of channel assignment and handoff supervision has been studied. It is shown that such techniques are quite feasible even in the worst multipath propagation conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High Frequency Transformer Designs for Improving Cross Regulation in Multiple-Output Flyback Converters (2007)

The cross regulation in multiple-output flyback converters is affected by leakage inductances of the transformers. The suitable winding arrangements of the transformers will lead to the improvement of cross regulation. This paper presents the comparative study of various winding arrangements in the three winding flyback transformers. The cross regulation model is considered in form of the resistance matrix related to the leakage inductance parameters. The design guidelines for the transformer for improving cross regulation are given based on the experimental results.
Through Silicon photonic via (TSPV) with Si core for low loss and high-speed data transmission in opto-electronic 3-D LSI (2010)

To realize very high performance computing system, we have proposed a novel opto-electronic 3-D LSI in which both electrical and optical devices are integrated. For realizing such opto-electronic 3-D LSI, through Si photonic via (TSPV) is indispensable for vertical light transmission. In this work, we fabricated the TSPV comprising Si core and epoxy cladding. We measured near field patterns (NFP) of laser light passed through the TSPV to evaluate its light confinement effect. From the results of NFP measurement, we confirmed that the laser light was successfully confined and propagated in the Si core region of the TSPV. We successfully developed a fabrication process to form both the TSPV and TSV simultaneously. The size of the fabricated TSPV and TSV was 20μm×20μm and 16μm×16μm, respectively.

Web Clipping: Compression Heuristics for Displaying Text on a PDA (2001)

While there is strong motivation to do so, reading Web pages on portable devices still leaves much to be desired. Most solutions need special versions of Web sites and do not cope adequately with resource limits of PDAs, in particular their small screen, which makes it difficult to display large amounts of information in a usable manner. We describe an approach that provides greater flexibility to users in selecting information they want displayed, while coping with display limitations by analyzing content and organizing it into abstract visualization levels. The user can zoom in and out successive levels of detail and navigate the content without being overwhelmed by clutter. We have developed heuristics for filtering text though task analysis and usability studies, whose results are described here. These studies provided meaningful insights to help us explore trade-offs between information filtering (and therefore text compression) and text comprehension.
Antibacterial temporary restorative materials incorporating polyethyleneimine nanoparticles. (2013)

Incorporation of 2% w/w QPEI NP may prominently improve the sealability and the antibacterial properties of TRMs. TRMs incorporating antibacterial nanoparticles may be clinically advantageous for sealing the endodontic access cavity to avoid reinfection of the root canal system during endodontic treatment.
Thrust Augmenting Ejectors, Part I (1983)

The solution of the equations representing the flow of a compressible fluid through an ejector has been shown to possess two distinctly different results after complete mixing. Part I of this study reported the analysis and described the performance of ejectors configured under the first solution where the flow after mixing is subsonic. The second solution to the ejector flow equations where the flow after mixing is supersonic provides a basis for selection of an optimal and a limiting ejector configuration for any given set of flight and injected gas characteristics. These special ejector configurations provide very high ideal thrust augmentations while translating from zero to supersonic velocities. Maps showing this ideal performance over large ranges of flight and injected gas characteristics are presented. Consideration is given to the influence of realistic, nonisentropic outlets as required for starting the supersonic flow (swallowing the starting shock wave) and for return of the supersonic mixed flow to ambient pressure. The data presented are limited to ejectors having a constant area mixing duct whose cross section is equal to 25 times that of the minimal area of the exhaust flow from the gas generator.
A meta‐analysis of durability data on conventional fixed bridges (1994)

A meta-analysis was performed on the dental literature since 1970, presenting clinical data of conventional bridges. 42 publications were found that contained durability data of conventional fixed bridges. These publications dealt with 33 different samples. According to the exclusion criteria 26 studies were excluded for the meta-analysis. The data of 4118 conventional bridges were analyzed. The calculated overall survival rate was 74.0 +/- 2.1% after 15 yr.

Green's theorem as a comprehensive framework for data reconstruction, regularization, wavefield separation, seismic interferometry, and wavelet estimation: A tutorial (2009)

Abstract Almost every link in the chain of exploration seismology methods used to process recorded data has been affected by Green's theorem. Among the seismic processes that can be related to, and/or have benefited from, Green's theorem are wavelet estimation, multiple elimination, regularization, redatuming, imaging, deghosting, and interferometry. This tutorial on various seismic exploration methods derived from Green's theorem emphasizes seismic data reconstruction (including regularization and redatuming) and its relationship to interferometry as well as to wavelet estimation and wavefield separation. The last decade has witnessed ever-increasing attention within the energy industry and its concomitant representation in the published literature to methods dealing with wavefield reconstruction through in-terferometry or virtual-source techniques. The attention has re- newed interest in Green's theorem because all different ap-proaches to interferometry can be derived from it. This tutorial provides a derivation and explication of the limitations of interferometric techniques (when interferometry is used to process measured data from marine surface seismic experiments with controlled sources) as approximations to Green's theorem. This tutorial provides a definite statement of the comprehensive framework given by Green's theorem to wavefield reconstruction and shows how different techniques are directly understood as specific mathematical forms and/or approximations to the theorem. The use of approximations can have shortcomings and create artifacts. These artifacts and errors are also analyzed and explained. All methods discussed in this tutorial recognize their foundation on Green's theorem and have a secure mathematical-physics cornerstone to recognize the assumptions behind distinct approximate solutions and to guide the search for more accurate, effective techniques.
Data analysis of music preferences of web users based on social and demographic factors (2022)

This study deals with the present-day problem of analyzing data of music preferences of web users based on social and demographic factors. The paper also analyzes the basic parameters of the user profile, which include such parameters as music preferences and movie preferences, personality traits, hobbies and interests, views on life, spending habits, phobias and health habits, and opinions, and demographics. The missing data imputation is carried out by multivariate imputation by chained equations. For analysis, 257 attributes are taken into account. Classification and Regression Trees were used as an algorithm for tree construction to find related variables to target variables "Opera" and "Classical music." Based on the constructed tree, the related preferences to classical music are found. It allowed the dissemination and promotion of the new performances and shows in the additional target group and extended the audience. An actual task of developing methods of web profile establishment is used for music preferences analysis. Random forest and KNN are the best predictors for chosen dataset in this study. The feature selection is organized based on random forest. This method allows to fond the most regularly preferences to classical music.
Microchannel Electrode Stimulation of Deep Peroneal Nerve Fascicles Induced Mean Arterial Depressor Response in Hypertensive Rats (2015)

Hypertension (HTN) affects over 1 billion people in the world, and while most are treated effectively with pharmacological regimens, 10–30% of them do not show a beneficial response. Electrical stimulation of the renal sympathetic, vagus and carotid sinus nerves has shown depressor effects and has been proposed as an alternative treatment for resistant hypertension (R-HTN). However, these nerves are heterogeneous in afferent/efferent composition, and their stimulation often results in unwanted side effects. We evaluated the possibility of eliciting a depressor response from stimulation of single fascicle of the somatic deep peroneal nerve (fDPN). A microchannel electrode array (µCEA) was used to stimulate the fDPN at low frequency, which induced a significant (p ≤ 0.03) transient reduction in mean arterial pressure (MAP) with no significant effects on heart rate. The depressor response was prolonged for several hours by extending the fDPN stimulation to 5 min, which induced significant reduction (17–25%) in MAP for up to 4 h. Immunofluorescence evaluation of the axonal marker, myelin, and active macrophages in the fDPN revealed no indication of nerve damage or overt inflammation in response to the procedure. This study provides evidence supporting the use of µCEA interfacing of small somatic nerve fascicles associated with cardiovascular relevant acupoints to induce significant reductions in MAP and opens the possibility of neuromodulation of small fascicles as an alternative strategy to treat R-HTN with minimal side effects. Further, the µCEA multielectrode array offers an effective tool for neuromodulation of small nerve fascicles, enabling a number of possible future medical bioelectronic applications.
Transparent nanohybrids of nanocrystalline TiO2 in PMMA with unique nonlinear optical behavior (2003)

PMMA is one of the most versatile polymeric materials for applications in various technological areas including optics and electro-optics. While the current applications of PMMA in optics and electro-optics are limited by their linear optical behavior, we report here in this paper the unique nonlinear optical behavior of nanohybrids consisting of nanocrystalline TiO2 in PMMA. Transparent thin films of TiO2–PMMA nanohybrid on substrates were synthesized by in-situ sol–gel and polymerisation, assisted by spin coating. Using titanium isoproproxide (Ti-iP) as the starting material for nanocrystalline titania, together with methyl methacrylate and 3-(trimethoxysilyl)propyl methacrylate, nanohybrids containing up to 80% Ti-iP in PMMA were successfully realized. The resulting nanohybrid thin films coated on quartz substrates are optically transparent and demonstrate large nonlinear optical behavior, with an ultrafast response of <1.5 ps. The highest two-photon absorption coefficient (β) and nonlinear refractive index (n2) are observed with the nanohybrid thin film of 60 wt% Ti-iP in PMMA, as confirmed by the Z-scan technique.

ROCK Inhibitor Y-27632 Increases the Cloning Efficiency of Limbal Stem/Progenitor Cells by Improving Their Adherence and ROS-Scavenging Capacity (2012)

Rho-associated coiled-coil kinase (ROCK) inhibitor Y-27632 has been shown to increase proliferative capacity and even immortalize primary keratinocytes. Here, we demonstrate that rabbit primary limbal epithelial cells (LECs) treated with Y-27632 also exhibited improved colony-forming efficiency by enhancing the expansion of the stem/progenitor cells. Moreover, Y-27632 treatment improved the rapid adherence of limbal stem/progenitor cells in the initial inoculation of primary cells. In addition, Y-27632 treatment elevated the intracellular glutathione level and decreased cellular reactive oxygen species (ROS) accumulation during the expansion of LECs. Therefore, ROCK inhibitor Y-27632 increased the cloning efficiency of rabbit limbal stem/progenitor cells by improving their adherence and ROS scavenging capacity.

Students As Authentic Researchers: A New Prescription for the High School Research Assignment (1999)

Can tenth graders go beyond writing reports to conduct “authentic” research? English teachers and the school librarian collaborate to gather data in a qualitative action research study that investigates the effectiveness of an assignment that requires primary research methods and an essay of two thousand words. The unit is designed as a performance-based assessment task, including rubrics, student journals, and peer editing. Students develop research questions, write proposals, design questionnaires and interviews, and learn techniques of display and analysis. Concurrently, their teachers gather data from observation, journals, and questionnaires to determine the strengths and weaknesses of the assignment. The research assignment has become analogous to “Take two aspirins and call me in the morning.” It doesn’t seem to do any harm and may even do some good. Educators adjust the dosage for older students: the length of the paper grows with the time allotted to the task but the prescription is the same. It is universally accepted as a benign activity, as evidenced by the prevalence of standards and objectives for research skills in school curricula. It has become a staple in the educational diet of the high school student. Librarians promote the research assignment because they want students to get better at searching, retrieving, and evaluating information. English teachers see it as an opportunity for sustained writing. Parents like it because it is good preparation for college. Everyone likes it because it gets students into the library and reading. So, what is wrong with research as it is traditionally taught in secondary schools? And what do students think?
Los ratios contables para describir y diagnosticar empresas que presentan signos de vulnerabilidad financiera en mercados latinoamericanos (2018)

En los ultimos anos se ha dado especial enfasis al estudio de las empresas que cotizan sus acciones en el mercado bursatil, haciendo hincapie en la informacion que brindan sus ratios contables en la identificacion de situaciones de vulnerabilidad o crisis financiera (cesacion de pagos, perdidas elevadas, estado de quiebra). De esta manera se consideraron las empresas que cotizan en los mercados de Chile, Peru, Colombia, Argentina y Brasil y se calcularon los indicadores contables provenientes de los estados financieros en el periodo 2000-2011. Los resultados obtenidos indican que los ratios financieros permiten caracterizar a las empresas segun su estado de vulnerabilidad financiera y de esa forma contribuir al diagnostico empresarial, aplicando herramientas exploratorias. Los metodos descriptivos permitieron construir valores de referencia de los ratios financieros que permitiran clasificar a una nueva empresa (en sana o en crisis) en un momento determinado en funcion de la informacion que proveen sus propios indices. Esto resulta de suma utilidad al momento de justificar el uso de determinados ratios en modelos de prediccion de crisis para empresas de economias emergentes, como las latinoamericanas, y avanzar en la modelizacion de la probabilidad de que una empresa pueda ingresar o no en un estado de crisis financiera.
GATA-2/estrogen receptor chimera regulates cytokine-dependent growth of hematopoietic cells through accumulation of p21WAF1 and p27Kip1 proteins (2002)

GATA-2 is considered to be essential for the development, maintenance, and function of hematopoietic stem cells (HSCs). However, it was also reported that GATA-2 inhibits the growth of HSCs. To examine the role of GATA-2 in the growth of hematopoietic cells, we introduced an estradiol-inducible form of GATA-2 (GATA-2/estrogen receptor [ER]) into interleukin 3 (IL-3)-dependent cell lines, Ba/F3, 32D, and FDC-P1. Estradiol-induced GATA-2 suppressed c-myc mRNA expression and inhibited IL-3-dependent growth in these clones. As for this mechanism, GATA-2 was found to inhibit ubiquitin/proteasome-dependent degradation of p21(WAF1) and p27(Kip1) and to induce their accumulation by repressing the expression of Skp2 and Cul1, both of which are components of the ubiquitin ligase for p21(WAF1) and p27(Kip1). Overexpression of c-myc restored the expression of Skp2 and Cul1 mRNA, reduced the amounts of p21(WAF1) and p27(Kip1) proteins, and canceled GATA-2-induced growth suppression, suggesting that down-regulation of c-myc expression may be primarily responsible for GATA-2-induced growth suppression. Next, we transduced retrovirus containing GATA-2/ER into murine bone marrow mononuclear cells (MNCs) and stem/progenitor (Sca-1(+)Lin(-)) cells. GATA-2/ER suppressed cytokine-dependent growth of MNCs and Sca-1(+)Lin(-) cells by about 70%, which was also accompanied by the reduced expression of c-myc, Skp2, and Cul1 mRNA and the accumulation of p21(WAF1) and p27(Kip1) proteins. In addition, the amount of GATA-2 protein was found to decline in hematopoietic stem/progenitor cells that were promoted to enter cell cycle by the stimulation with cytokines. These results suggest that GATA-2 may regulate expression levels of p21(WAF1) and p27(Kip1), thereby contributing to the quiescence of hematopoietic stem/progenitor cells.
