Sampling Strategies for Active Learning in Personal Photo Retrieval (2006)

With the advent and proliferation of digital cameras and computers, the number of digital photos created and stored by consumers has grown extremely large. This created increasing demand for image retrieval systems to ease interaction between consumers and personal media content. Active learning is a widely used user interaction model for retrieval systems, which learns the query concept by asking users to label a number of images at each iteration. In this paper, we study sampling strategies for active learning in personal photo retrieval. In order to reduce human annotation efforts in a content-based image retrieval setting, we propose using multiple sampling criteria for active learning: informativeness, diversity and representativeness. Our experimental results show that by combining multiple sampling criteria in active learning, the performance of personal photo retrieval system can be significantly improved
Coordinated data prefetching by utilizing reference information at both proxy and web servers (2001)

Existing prefetching techniques rely on server-based, proxy-based, or client-based reference access information. Although Web servers may provide accurate access information, our studies show that significant communication overhead can be involved by sending unnecessary reference information to clients or/and proxy servers. Our study also shows that prediction accuracy of proxy-based prefetching can be significantly limited without input of Web servers. We propose a coordinated proxy-server prefetching technique that adaptively utilizes the reference information and coordinates prefetching activities at both proxy and web servers. In our design, the reference access information stored in proxy servers will be the main source serving data prefetching for groups of clients, each of whom shares the common surfing interests. The access information in the web server will be used to serve data prefetching only for data objects that are not qualified for proxy-based prefetching. Conducting trace-driven simulations, we show that both hit ratios and byte hit ratios contributed from coordinated proxy-server prefetching are are up to 88% higher than that from proxy-based prefetching, and they are comparable to the ratios from server-based prefetching with a difference of 5%.
Rapid amplification and fixation of new restriction sites in the ribosomal dna repeats in the derivatives of a cross between maize and <i>Tripsacum dactyloides</i> (1985)

Abstract Some of the derivatives of a cross of maize ( Zea mays L.) × Tripsacum dactyloides (L) L (2n = 72) have abnormal development leading to strange and striking morphologies. The Tripsacum chromosomes in these “tripsacoid” maize plants (with Tripsacum ‐like characteristics) were eliminated and the maize chromosomes were recovered through repeated backcrossing to maize. As an initial attempt to analyze the DNA alterations in tripsacoid maize, we have detected a few restriction site changes in the ribosomal DNA repeat of these plants (Hpa II, Bal I, Sst I, Mbo II, and Sph I) and a new Sph I site was mapped to the spacer region between the 26S and 17S genes. Several possible mechanisms for the generation of a new restriction site are discussed, and we propose that the transient presence of Tripsacum genome during the backcrossing in some way induced a rapid amplification and fixation of new restriction sites in a relatively short period of time.
Non-O157:H7 Stx2-Producing <i>Escherichia coli</i> Strains Associated with Sporadic Cases of Hemolytic-Uremic Syndrome in Adults (1998)

From August 1996 to May 1997, six verotoxin-producing Escherichia coli (VTEC) strains were isolated from stool specimens of adults suffering from hemolytic-uremic syndrome (HUS). All the isolates were stx2 positive and belonged to different serotypes: O6:H4, O91:H10, O91:H21, O rough:H16, OX3:H-, and O nontypeable: H-. The enterohemolysin (Ehly)-encoding genes were detected in two isolates, and none of the isolates harbors the intimin (Eae)-encoding gene. These findings suggest that stx2-positive non-O157:H7 VTEC is a major cause of HUS in adults and that several sources of pathogens are responsible for local endemic infections.
A Review of Microwave Thermography Nondestructive Testing and Evaluation (2017)

Microwave thermography (MWT) has many advantages including strong penetrability, selective heating, volumetric heating, significant energy savings, uniform heating, and good thermal efficiency. MWT has received growing interest due to its potential to overcome some of the limitations of microwave nondestructive testing (NDT) and thermal NDT. Moreover, during the last few decades MWT has attracted growing interest in materials assessment. In this paper, a comprehensive review of MWT techniques for materials evaluation is conducted based on a detailed literature survey. First, the basic principles of MWT are described. Different types of MWT, including microwave pulsed thermography, microwave step thermography, microwave pulsed phase thermography, and microwave lock-in thermography are defined and introduced. Then, MWT case studies are discussed. Next, comparisons with other thermography and NDT methods are conducted. Finally, the trends in MWT research are outlined, including new theoretical studies, simulations and modelling, signal processing algorithms, internal properties characterization, automatic separation and inspection systems. This work provides a summary of MWT, which can be utilized for material failures prevention and quality control.

Amino‐acid sequence of ribonuclease T<sub>2</sub> from <i>Aspergillus oryzae</i> (1988)

The amino acid sequence of ribonuclease T2 (RNase T2) from Aspergillus oryzae has been determined. This has been achieved by analyzing peptides obtained by digestions with Achromobacter lyticus protease I, Staphylococcus aureus V8 protease, and alpha-chymotrypsin of two large cyanogen bromide peptides derived from the reduced and S-carboxymethylated or S-aminoethylated protein. Digestion with A. lyticus protease I was successfully used to degrade the N-terminal half of the S-aminoethylated protein at cysteine residues. RNase T2 is a glycoprotein consisting of 239 amino acid residues with a relative molecular mass of 29,155. The sugar content is 7.9% (by mass). Three glycosylation sites were determined at Asns 15, 76 and 239. Apparently RNase T2 has a very low degree of sequence similarity with RNase T1, but a considerable similarity is observed around the amino acid residues involved in substrate recognition and binding in RNase T1. These similar residues may be important for the catalytic activity of RNase T2.
Advanced distillation saves energy and capital (1997)

Although new separation methods are continuously being explored, distillation remains the most frequently used separation process. It is well known that distillation is both energy intensive and inefficient. Compared to conventional column sequences, one particular configuration--the fully thermally coupled distillation column--can save significant amounts of energy by reducing thermodynamic losses. In such a setup, a number of columns (typically two) are linked together through vapor and liquid streams without reboilers or condensers between the columns. One practical application of the fully thermal coupled column has been known for a long time. However, lack of design experience and fear of operational and control problems, have prevented its widespread use to date. In addition to energy savings, divided-wall columns can save capital costs, by reducing the number of column shells, reboilers and condensers. The divided-wall column can be applied with real benefits in a variety of refinery, gas separation and chemical processes. Generally, the technology should be considered in any ternary (three-component) separation, as a possible low-cost alternative to conventional schemes. Generic guidelines for the use of divided-wall columns are discussed. The application of the divided-wall column for natural gas liquids separation is also presented.
Interferon alpha-2 (IFN alpha 2) increases lacrimal and salivary function in Sjögren's syndrome patients. Preliminary results of an open pilot trial versus OH-chloroquine. (1997)

This study shows that IFN can improve tear function and dry mouth in SS, without causing significant side effects.
Error-reduction methods for shape measurement by temporal phase unwrapping (1997)

Temporal phase unwrapping is a method of analyzing fringe patterns in which the fringe phase Φ at each pixel is measured and unwrapped as a function of time t. We propose two methods for improving the signal-to-noise ratio of the total phase change by incorporating data from the intermediate phase values. The first involves fitting the expected curve to the measured phase history; the second involves Fourier transformation of the corresponding phasors. The performance of these methods is compared both experimentally, with data from a fringe projector based on a spatial-light modulator, and numerically. It is shown that the optimum performance is given by the Fourier transform method. The best way to use the first method is with Φ decreasing exponentially with time from its maximum value to zero; this provides significant improvements in reliability, accuracy, and computation time compared with the original temporal unwrapping algorithm.

Wound Healing and Anti-Inflammatory Effect in Animal Models of<i>Calendula officinalis</i>L. Growing in Brazil (2012)

Calendula officinalis is an annual herb from Mediterranean origin which is popularly used in wound healing and as an anti-inflammatory agent. In this study, the ethanolic extract, the dichloromethane, and hexanic fractions of the flowers from plants growing in Brazil were produced. The angiogenic activity of the extract and fractions was evaluated through the chorioallantoic membrane and cutaneous wounds in rat models. The healing activity of the extract was evaluated by the same cutaneous wounds model through macroscopic, morphometric, histopathologic, and immunohistochemical analysis. The antibacterial activity of the extract and fractions was also evaluated. This experimental study revealed that C. officinalis presented anti-inflammatory and antibacterial activities as well as angiogenic and fibroplastic properties acting in a positive way on the inflammatory and proliferative phases of the healing process.
Anticardiolipin Antibodies and the Risk for Ischemic Stroke and Venous Thrombosis (1992)

An anticardiolipin antibody level above the 95th percentile is an important risk factor for deep venous thrombosis or pulmonary embolus but not for ischemic stroke in healthy adult men.
Wavelength tunable source of subpicosecond pulses from CW passively mode-locked two-section multiple-quantum-well laser (1993)

A wavelength-tunable passively-mode-locked semiconductor laser source of subpicosecond pulses is demonstrated. The system includes a two-section multiple-quantum-well laser which is coupled to an external grating for tuning and is followed by an external grating pair for pulse compression. A tuning range of 16 nm round 846 nm is obtained, resulting in compressed pulse widths as short as 260 fs and pulse widths shorter than 600 fs for all wavelength values within this tuning range. Time-bandwidth products are one to two times the transform limit.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Single-Cell Analysis of Glucocorticoid Receptor Action Reveals that Stochastic Post-Chromatin Association Mechanisms Regulate Ligand-Specific Transcription (2006)

The glucocorticoid receptor (GR) dynamically interacts with response elements in the mouse mammary tumor virus (MMTV) promoter to regulate steroid-dependent transcription. In a clonal mammary carcinoma cell line containing a tandem array of MMTV promoter-reporter gene cassettes integrated at a single genomic locus, direct binding of a green fluorescent protein (GFP)-GR fusion protein to the MMTV regulatory elements can be observed in living cells. After ligand treatment, MMTV-dependent transcription in individual cells was detected by RNA fluorescence in situ hybridization (FISH). High-resolution fluorescence images were acquired from large numbers of randomly selected cells. Images were analyzed with a novel automated computer algorithm, measuring the RNA FISH signal and the relative GFP-GR fluorescence intensity at the MMTV array for each cell. Although dexamethasone increased the mean RNA FISH signal approximately 10-fold, RU486 produced only about a 2-fold induction, as expected for this mixed antagonist. For all treatment conditions, the relative GFP-GR fluorescence at the array for the averaged cells paralleled the RNA FISH measurements, suggesting that image analysis accurately detected an increase in steady-state GR association with the MMTV array that was responsible for the increase in transcriptional activity. The antagonist-dependent decreases in GR association with the MMTV promoter were confirmed by chromatin immunoprecipitation experiments, supporting the image analysis results. A pronounced cell-to-cell variability was observed in RNA FISH signal and GR-MMTV association within treatment groups. We observed a nonlinear relationship between GR-MMTV association and RNA FISH in individual cells, indicating that differences in GR-MMTV interaction account for some, but not all, of the transcriptional heterogeneity between individual cells. In selected cell subpopulations with equal levels of GR-MMTV association, there was a decrease in RNA FISH signal with RU486 treatment compared with dexamethasone treatment. These results indicate that stochastic events occurring after GR-promoter association, such as the actions of chromatin remodeling complexes or other cofactors, change in a ligand-dependent manner and regulate heterogeneous transcription in individual cells.
Hormones and the Stressed Brain (2004)

The stress system orchestrates brain and body responses to the environment. Cortisol (in humans) or corticosterone (in rodents) are important mediators of the stress system. Their action-in concert-is crucial for individual differences in coping with other individuals, which in turn depend on genetic- and experience-related factors. The actions exerted by cortisol and corticosterone have an enormous diversity. They include the regulation of rapid molecular aggregations, membrane processes, and gene transcription. In the latter transcriptional regulation, the corticosteroid hormones have two modes of operation. One mode is mediated by high-affinity mineralocorticoid receptors (MRs), which control gene networks underlying stabilization of neuronal activity as determinant for the sensitivity to trigger immediate responses to stress organized by corticotrophin-releasing hormone (CRH)-1 receptor. Whereas disturbance of homeostasis is prevented by MR-mediated processes, its recovery is facilitated via the low-affinity glucocorticoid receptors (GRs) that require stress levels of cortisol. GRs promote in coordination with CRH-2 receptors and the parasympathetic system behavioral adaptation and enhances storage of energy and information in preparation for future events. The balance in the two stress system modes is thought to be essential for cell homeostasis, mental performance, and health. Imbalance induced by genetic modification or stressors changes specific neural signaling pathways underlying cognition and emotion. This yin-yang concept in stress regulation is fundamental for genomic strategies to understand the mechanistic underpinning of corticosteroid-induced stress-related disorders such as severe forms of depression.
Transferrin Enzyme Immunoassay for Quantitative Monitoring of Blood Contamination in Saliva (2004)

When blood components are present in the oral mucosa, quantitative estimates of salivary hormone concentrations may be compromised (1). Blood and its components can leak into the oral mucosa as a result of micro injuries such as burns or abrasions. The probability of blood leakage is increased with poor oral health (i.e., periodontal disease), certain infectious diseases (e.g., HIV) (2), and behavior known to influence oral health negatively (e.g., smoking) (3). Few studies, however, have investigated methods to determine blood contamination in saliva.

The Hemastix® Reagent Strip for Urinalysis has been used to test for blood in saliva (4)(5). This method detects the pseudoperoxidase activity of hemoglobin; thus, endogenous salivary peroxidases produce false-positive results for hemoglobin.

To provide a quantitative measure of blood contamination in saliva, we developed an enzyme immunoassay for transferrin, which is present in very small amounts ( 1000 mg/L). We expect that serum and salivary concentrations of transferrin are not correlated and that transferrin, with a formula weight of 76 000 and radius of 5 nm, would reach saliva in high concentrations only when the barrier between blood and saliva is compromised.

Saliva (by passive drool) and serum samples were collected without stimulation simultaneously from 40 young adults. The Pennsylvania State University Institutional Review Board approved all procedures, and informed consent was obtained. All samples were stored at −40 °C. All samples were thawed, vortex-mixed, and centrifuged at 1500 g for 15 min before assay for serum transferrin, salivary transferrin, or testing by Hemastix Reagent …
A Chiral Thioxanthone as an Organocatalyst for Enantioselective [2+2] Photocycloaddition Reactions Induced by Visible Light (2014)

Abstract Thioxanthone 1 , which was synthesized in a concise fashion from methyl thiosalicylate, exhibits a significant absorption in the visible light region. It allows for an efficient enantioselective catalysis of intramolecular [2+2] photocycloaddition reactions presumably by triplet energy transfer.
A Stable 4th-Order Delta-Sigma Modulator with an FIR predictor (1992)

A novel approach for a stable high-order delta-sigma modulator is presented. The modulator provides 16 bit resolution at 20kHz bandwidth using 4th-order noise shaping structure at an oversampling ratio of 64. The modulation loop is completely stabilized by an FIR prediction technique. The architecture inherently has less sensitivity to component mismatch. The total hardware is much the same as the noise shaping integrators.
Sorbent - Containing Storage Systems for Natural Gas Powered Vehicles (1983)

<div class="htmlview paragraph">Natural gas can be used as a vehicular fuel, but its low energy density is a significant drawback. The energy density can be increased by adsorption of the natural gas on high surface area sorbents. The adsorption of methane on activated carbons and molecular sieves was investigated at pressures up to 16 MPa (2300 psig). The improvement in methane storage capacity over empty cylinders is appreciable at low pressures but diminishes as the pressure increases. When adsorbed, for example, on 9LXC activated carbon at 3, 7, and 14 MPa the energy density increased by 245%, 100%, and 53%, respectively. Less improvement was observed with molecular sieves.</div>
Femotosecond optical pulse compression with Gires-Tournois interferometers (1986)

Recent progress in colliding pulse mode-locked (CPM) dye laser systems has shown that it is absolutely indispensable to control the group velocity dispersion (GVD) in the laser cavity to obtain stable trains of nearly bandwidth-limited femtosecond pulses.1,2 So far the most successful approach in this direction has been a four-prism configuration used by Valdmanis et al,1 who were able to generate transform-limited pulses of only 27-fs duration. We report here on the applicability of thin-film Gires-Tournois interferometers3 (GTIs), which can be used for the compression of chirped femtosecond pulses4 as well as for intracavity chirp compensation in a CPM laser.2
First-Year Composition and the Common Core: Educating Teachers of Writing Across the High School-College Continuum (2014)

This article will discuss the implications of the Common Core State Standards (CCSS) on the education of writing instructors at the college level. The article suggests that, with the adoption of the CCSS, the most effective models of the training of writing teachers in higher education will now include collaboration with educators at the K-12 level. A model for this kind of collaborative work is described, based on an effort the author is currently leading as the Director of English Composition at my institution. A brief overview of the CCSS, and the shifts in the teaching and learning of English Language Arts at the K-12 level they suggest, is provided. The article then discusses how this collaborative model of K-16 teacher education can help us understand the strengths and weaknesses of beginning college writers, from the perspectives of both high school and college teachers, and how this understanding should then inform the instruction of first-year composition teachers. Finally, the article will suggest that it is essential that the education of secondary and post-secondary writing teachers is grounded in current theories and practices of the field of composition and rhetoric, and more specifically, the paradigm of "academic literacies" as developed by Mary Lea and Brian Street.
