Certificate discovery using SPKI/SDSI 2.0 certificates (1998)

In this thesis, a framework was designed to implement certificate discovery in SPKI/-SDSI. The process of discovering a valid certificate chain is shown to be analogous to a string re-writing problem of finding certain string derivations. Given this framework, an algorithm was devloped to solve the problem and is shown to a time polynomial in the number of certificates. Given the theoretical framework, two certificate discovery implementations were developed. The first, written in Perl, tooks a simple certificate format and generated the necessary sequence based upon the chain desired. The second implementation, in C, was written as part of a library that is designed for the SPKI/SDSI framework.
The Dynamic Impact of Fundamental Tax Reform Part 2: Extensions (1998)

In this second of two articles on the economic impact of fundamental tax reform, Gregory Huffman and Evan Koenig extend their earlier framework for analyzing how the adoption of a flat-rate consumption tax would affect the economy over time. They argue that if tax reform is to be successful in stimulating investment and raising long-run living standards, then it is important that ways be found to avoid increasing the rate of labor-income taxation. Increases in labor-income tax rates can undo the positive economic effects of a cut in the rate of capital-income taxation. Conversely, cuts in labor-income tax rates reinforce savings incentives and contribute to higher steady-state levels of consumption. Huffman and Koenig also demonstrate that the economys immediate response to tax reform is mutedand the overall adjustment process can be substantially prolongedwhen firms find it expensive to add quickly to their stocks of plant and equipment.
A proteomic approach to the identification of heterogeneous nuclear ribonucleoproteins as a new family of poly(ADP-ribose)-binding proteins (2003)

A new class of poly(ADP-ribose) (pADPr)-binding proteins, heterogeneous nuclear ribonucleoproteins (hnRNPs), has been identified by a proteomic approach using matrix-assisted laser-desorption-ionization time-of-flight ('MALDI-TOF') MS. Liquid-phase isoelectric focusing with a Rotofor cell (Bio-Rad) allowed pre-fractionation of proteins extracted from HeLa cells. Rotofor protein fractions were further separated by SDS/PAGE and then transferred to a PVDF membrane. pADPr-binding proteins were analysed by autoradiography of the protein blot after incubation with (32)P-labelled automodified pADPr polymerase-1 (PARP-1). Peptide mass fingerprinting of selected bands identified the most abundant pADPr-binding proteins as hnRNPs, a family of proteins that bind pre-mRNA into functional complexes involved in mRNA maturation and transport to the cytoplasm. Sequence homology database searching against a previously reported pADPr-binding sequence motif revealed that the hnRNPs contain a putative pADPr-binding sequence pattern [Pleschke, Kleczkowska, Strohm and Althaus (2000) J. Biol. Chem. 275, 40974-40980]. pADPr-binding assays performed with synthetic peptides by the dot-blot technique and with nitrocellulose-transferred recombinant hnRNPs confirmed the pADPr-binding protein identification and the specificity of the interaction. These results could establish a link between increased levels of pADPr in DNA damaged cells and the modified protein expression pattern resulting from altered mRNA trafficking.

HSP70 and ribosomal protein L2: novel 5S rRNA binding proteins in <i>Escherichia coli</i> (2000)

A Northwestern analysis of Escherichia coli total proteins with radiolabeled 5S rRNA identified two novel 5S rRNA interacting proteins, a 70 kDa and a 37 kDa protein, and three ribosomal proteins reported on already. The N-terminal sequencing of the 70 kDa protein separated by SDS-PAGE from the high-salt-washed fraction of crude ribosome led to the discovery of a polypeptide identical in its first 10 amino acid residues to E. coli heat shock protein 70. The N-terminal eight amino acid sequence of the 37 kDa protein extracted from the high-salt-washed ribosome is identical to that of the ribosomal protein L2. In addition, the interaction of these proteins with 5S rRNA has been confirmed with gel mobility shift assays.
Investigation on the long term reliability of power IGBT modules (2002)

More than forty 300 A/400 A 1200 V IGBT modules, coming from different manufactures, were studied by an intermittent operating life test (power cycling) in order to estimate the long term reliability of the modern power IGBT modules. The test results and the failure analysis results indicate that no module could pass 10/sup 6/ power cycles and most tested modules failed in emitter bonding wire lifting from the bonding pad. Besides, recrystallization and migration in bonding pad metallization, electrothermal migration caused bonding wire breaking, and local overheat induced die burn-out failure were also observed in this study.
Medroxyprogesterone acetate therapy in hirsutism (1985)

In a pilot study, 26 hirsute females were treated with medroxyprogesterone acetate (MPA). We used an ointment containing 0.2% MPA in 13 patients, subcutaneous injection of MPA into the hairy areas of the face in five patients and intramuscular injection of low doses of MPA in 13 patients, each for an average duration of 16 weeks. The best clinical result was achieved by subcutaneous injection, the next most successful was the intramuscular injection, and the least successful was the topical application. Hair diameter measurements, carried out in 12 patients, were found to be reduced by 33% on average. Serum androgen levels, measured monthly, remained unaffected by topical treatment, but were decreased by intralesional and intramuscular injection. The clinical improvement with topical therapy despite the lack of effect on serum androgen levels supports the idea that MPA works partly at the cellular level. The intralesional and systemic injection of MPA may exert an effect both by systemic androgen suppression and a local action.
Deal with the Item 8 of Rosenberg Self Esteem Scale (1965) and Revalidate the Factor Structure: Based on Measuring Groups of Middle School Students (2014)

Using Rosenberg Self Esteem Scale (1965), we have measured 1889 students in schools. Through correlation analysis, item analysis, exploratory factor analysis and confirmatory factor analysis, we study two different ways in dealing with the item 8 of Rosenberg Self Esteem Scale (Rosenberg, 1965), namely the score is counted according to the positive item method and deleting the item 8, explore factor models of the scale and verify the goodness of fit of different models. Our results show: (a) the item 8 should be reserved. It should adopt that the score is counted according to the positive item method. The score correlating with the total score is 0.33 (P < 0.01); (b)if the factor analysis uses two factors，the two factor correlation model has better goodness of fit (χ2/df=6.12, CFI=0.95, TLI=0.93, RMSEA=0.06), namely the two factor model can be used in the scale.
High-speed planar-structure Inp/InGaAsP/InGaAs avalanche photodiode grown by VPE (1984)

Planar-structure InP/InGaAsP/InGaAs avalanche photo-diodes have been realised by using a VPE-growth technique and a Be+ implanted guard ring. Sensitivity measurement has been performed at 1.3 μm and 1.8 Gbit/s. The minimum average received level required for 10−9 BER was −31.3 dBm, which was 1.2 dB better than the value for the Ge-APD.

'Griffis Collection' is a collection of photographs of Japan and Korea in modern era, collected by William Elliot Griffis. Originally Mr. Griffis was studying about Japan when he developed an interest on Korea, and started to collect helpful materials he could find to study. Later days of Griffis' life, he donated his research to Rutgers University Library, and those materials were named and preserved as Griffis Collection. This paper is about photographs that illustrate modern Incheon and Hansung, and study them in order to discover how Korea's modern cities and architecture were formed and built. In total, there is four categorized chapters of photographs, and those are cities, public buildings, educational facilities and private buildings. In Griffis Collection, there are 23 photos those are relate to this paper's subject, but only 19 of them that has historic value has been covered in this paper. In results, all 19 photos were proved that they have significant information in terms of historic research of modern Korea and Korea's modern architectural stages.

Towards a security architecture for substations (2011)

The security of the electricity delivery system has received much attention recently with increasing focus on Smart Grids. While substations used to be protected by concrete walls and barbed wire, today the industry is getting worried about attacks over the communication infrastructure. In this paper, we analyse the primary threats and present a first cut of a security architecture. We suggest security policy options for utilities, as well as protocols to do key management for substations. We conclude that the priority should be to secure the electronic perimeter of substation - as this has the maximum impact. Authentication should be done at the level of the substation station room rather the substation bays. Using cryptography for authentication inside substation bays does not have significant benefits, but is likely to bring fragility instead.
Cancer Stem Cells (CSCs) in Drug Resistance and their Therapeutic Implications in Cancer Treatment (2018)

Cancer stem cells (CSCs), also known as tumor-initiating cells (TICs), are suggested to be responsible for drug resistance and cancer relapse due in part to their ability to self-renew themselves and differentiate into heterogeneous lineages of cancer cells. Thus, it is important to understand the characteristics and mechanisms by which CSCs display resistance to therapeutic agents. In this review, we highlight the key features and mechanisms that regulate CSC function in drug resistance as well as recent breakthroughs of therapeutic approaches for targeting CSCs. This promises new insights of CSCs in drug resistance and provides better therapeutic rationales to accompany novel anticancer therapeutics.
Establishing the diffuse correlation spectroscopy signal relationship with blood flow (2016)

Diffuse correlation spectroscopy (DCS) measurements of blood flow rely on the sensitivity of the temporal autocorrelation function of diffusively scattered light to red blood cell (RBC) mean square displacement (MSD). For RBCs flowing with convective velocity [Formula: see text], the autocorrelation is expected to decay exponentially with [Formula: see text], where [Formula: see text] is the delay time. RBCs also experience shear-induced diffusion with a diffusion coefficient [Formula: see text] and an MSD of [Formula: see text]. Surprisingly, experimental data primarily reflect diffusive behavior. To provide quantitative estimates of the relative contributions of convective and diffusive movements, we performed Monte Carlo simulations of light scattering through tissue of varying vessel densities. We assumed laminar vessel flow profiles and accounted for shear-induced diffusion effects. In agreement with experimental data, we found that diffusive motion dominates the correlation decay for typical DCS measurement parameters. Furthermore, our model offers a quantitative relationship between the RBC diffusion coefficient and absolute tissue blood flow. We thus offer, for the first time, theoretical support for the empirically accepted ability of the DCS blood flow index ([Formula: see text]) to quantify tissue perfusion. We find [Formula: see text] to be linearly proportional to blood flow, but with a proportionality modulated by the hemoglobin concentration and the average blood vessel diameter.
The neural type II regulatory subunit of cAMP-dependent protein kinase is present and regulated by hormones in the rat ovary. (1986)

In this study purified isoforms of rat ovarian regulatory subunit of type II cAMP-dependent protein kinase (R-II) were compared with R-II purified from rat brain. A special neural form of R-II has been previously described in bovine brain. Analysis by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis resolved three isoforms of rat ovarian R-II (R-II54, Mr = 54,000; R-II52, Mr = 52,000; and R-II51, Mr = 51,000) compared to two R-II isoforms in rat brain (R-II54 and R-II52). Polychromatic silver-stained peptide maps of purified R-II subunits indicated that peptides generated from both rat ovarian R-II52 and R-II51 were similar (if not identical) to the peptides of the neural form, R-II52, purified from rat brain. These peptides differed markedly from those generated from R-II54 of either rat ovary, brain, or heart. Ovarian R-II52/51 photoaffinity labeled with 8-N3-[32P]cAMP and analyzed by two-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis was shown to consist of three (rather than two) isoelectric variants, which were similar to three variants resolved from rat brain R-II and clearly distinct from that of rat heart R-II54. An antibody which recognized both the R-II54 and R-II52/51 isoforms of rat ovarian extracts also recognized both forms of rat brain R-II (R-II54 and R-II52) and similar forms in extracts of rat adrenal and parotid glands. These results strongly suggest that the R-II52 isoform previously designated as a neural specific form of R-II is present in high concentrations in a nonneural tissue, the rat ovary.
ESTATÍSTICAS SOBRE IRRIGAÇÃO NAS REGIÕES SUL E SUDESTE DO BRASIL SEGUNDO O CENSO AGROPECUÁRIO 2005-2006 (2012)

1 RESUMO A pesquisa objetivou contribuir para o debate sobre a melhoria das estatísticas sobre a irrigação no Brasil, mais incisivamente quanto às regiões Sul e Sudeste. Foram utilizados dados do Censo Agropecuário 2005-2006, apresentando os resultados de acordo com a indicação de uso da irrigação e área irrigada por Estado dessas regiões, comparando, ainda, com trabalhos de análise dos dados e informações do Censo Agropecuário 1995-1996. A área irrigada no Brasil, de acordo com o Censo Agropecuário 2005-2006 é de 4,45 milhões de hectares. A região Sudeste apresenta a maior área irrigada, equivalente a 35,6% da área total irrigada. Em segundo lugar está a região Sul com, aproximadamente, 27%; pois o restante da área irrigada, encontra-se nas demais regiões. O método de irrigação por superfície predomina apenas na região Sul (82,2%), enquanto na região Sudeste, a aspersão é o método mais utilizado. Constatou-se que o método por superfície está sendo substituído pelos outros métodos de irrigação, principalmente, pelo método da aspersão; já a irrigação localizada representa a menor área. O Censo 2005-2006 realizou levantamentos precisos, mas no que se refere à irrigação no Brasil ainda é possível se encontrar divergências numéricas entre o Censo Agropecuário, e as informações publicadas na literatura. PALAVRAS-CHAVE: água, IBGE, métodos de irrigação, Brasil. SARAIVA, K. R.; SOUZA, F. de STATISTICS ON IRRIGATION IN THE SOUTH AND SOUTHEAST REGIONS OF BRAZIL, ACCORDING TO THE 2005-2006 AGRICULTURAL CENSUS 2 ABSTRACT This research aims at contributing to the debate on improving statistics on irrigation in Brazil, specially statistics on the the South and Southeast regions. We used data from the 2005-2006 Agriculture Census, presenting the results by the indication for use of irrigation and by irrigated area by state on these regions, comparing them also with works on data analysis and with information from the 1995-1996 Agriculture Census. The irrigated area in Brazil, according to the 2005-2006 Agriculture Census is 4.45 million hectares. The Southeast region has the largest irrigated area, equivalent to 35.6% of the total irrigated area. The South region is second in irrigated area, with approximately 27%. The surface irrigation system predominates only in the South Region (82.2%), while in the Southeast Region, the spray irrigation system is the most widely used. It was found that surface irrigation is being replaced by other systems, mainly by spray irrigation, while localized irrigation is used in the smallest area. The 2005-2006 Census conducted surveys accurate, but with regard to irrigation in Brazil is still possible to find numerical differences between the Census of Agriculture, and the information published in the literature. KEYWORDS: water, IBGE, irrigation systems, Brazil.
Media for Extremely High Density Recording (2006)

The development and engineering of the magnetic material that stores information largely determines the progress of magnetic storage technology, as epitomized by magnetic hard disks. In this chapter, we consider the ultimate capability for the storage of digital information. Noise performance and spatial resolution are key parameters in recording media and an ongoing challenge in advancing the areal density. The dominant media noise source today is transition jitter noise, or the uncertainty in positioning neighboring bit transitions. In sputtered media, it reflects the finite size, random positioning and dispersions in size, orientation and magnetic properties of the fine grains that comprise the media. Highly anisotropic materials, combined with heat-assisted magnetic recording (HAMR), promise significant reductions in the average, thermally stable grain size from currently about 7–9 nm in Co-alloys to about 2–3 nm in FePt-based media. In addition, self-organized magnetic arrays (SOMA) promise a significant reduction in jitter noise, because they yield nearly monodisperse magnetic nanoparticles such as FePt and Co. SOMA media may serve not only as conventional media with reduced dispersions and media with bit-transitions defined by rows of particles, but may also be scaled to the ultimate goal of single-particle-per-bit recording. In this last scenario, the eventual areal density is governed by the minimal thermally stable size and by the center-to-center spacing of neighboring particles. Ultimately, subject to the mastering of all writability, signal retrieval, bit-addressability and spacing issues, areal densities of the order of 40–50 terabit per square inch may be reached.
An optimal synthetic aperture for circular tomosynthesis (1989)

In circular tomosyntesis obtained from a sufficient number of radiographs with projection directions forming a single cone, object detail at a distance from the plane of interest is blurred according to the zero order Bessel function. The main lobe of this window function defines slice thickness, while its ringing side lobes are undesirable because they permit further outlying structures to “leak” through. Using the orthogonality of Bessel functions, a sampling scheme consistmg of multiple, concentric projection cones was designed to synthesize by a finite FourierBessel series a slice window with superior side lobe suppression. The window that concentrates the most “energy” within a finite slice, and can be realized by a limited number of sampling cones, is the zero order circular prolate spheroidal function. Its application to tomosynthesis of 3 mm thick slices with a characteristic detail size of 0.5 mm, concentrated 95% of the total series expansion to only 3 concentric circular scans, yielding a theoretical suppression of the first side lobe of − 38 dB, to be compared to − 8 dB achieved with the Bessel function. Experimental implementation of this optimal sampling scheme using 3, 8, and 14 projection views, distributed over cones with opening half‐anges of 1.92, 4.39, and 6.88°, respectively, resulted in a side‐lobe attenuation of at least − 20 dB. This attenuation reduced significantly artifacts arising from out‐of‐plane detail of high spatial frequency (e.g., edges) in tomosynthetic images of clinical interest in dentistry.
Am“B”valent: anti-CD20 antibodies unravel the dual role of B cells in immunopathogenesis (2010)

Accumulating evidence has designated B cells as central players in the pathogenesis of immune diseases. In the late 1990s, anti-CD20 monoclonal antibodies were developed for the treatment of B-cell non-Hodgkin lymphomas, offering the opportunity to efficiently deplete the B-cell compartment for therapeutic immunointerventions. Several studies have since established the beneficial effect of this drug on the course of a wide range of immune diseases. However, paradoxically, it has also been reported that rituximab sometimes worsens the symptoms of the very same conditions. The explanation that reconciles such apparently conflicting results has recently emerged from basic studies, which demonstrate that (1) B cells are also endowed with immune-regulatory properties and (2) the opposing contributions of B cells may overlap during the course of the disease. Caution should therefore be exercised when considering B-cell depletion because the therapeutic effect will depend on the relative contributions of the opposing B-cell activities at the time of the drug administration.
Declogging Small‐Bore Feeding Tubes (1987)

Nine substances (Pancrease, Viokase, pork pancreatin, bromelain, papain, cranberry juice, Coca-Cola, chymotrypsin, and distilled water) were tested every half-hour for 4 hr using 900 mm of water pressure to determine their effectiveness in declogging small-bore feeding tubes. At the end of 4 hr the tubes were irrigated with air using a 50-cc syringe. None of the substances tested were effective within 4 hr. Three substances allowed for successful syringe irrigation at the end of 4 hr. They were: chymotrypsin, papain, and distilled water.
Photochromism of a water-soluble vesicular [2.2]paracyclophane-bridged imidazole dimer (2011)

Here we report the first photochromism of a newly designed [2.2]paracyclophane-bridged imidazole dimer in water. The photochromic dye with a hydrophilic and a hydrophobic substituent forms vesicles in water and shows instantaneous colouration upon UV light irradiation and successive rapid fading in the dark.
