Mithramycin selectively inhibits collagen-alpha 1(I) gene expression in human fibroblast. (1993)

The products of the collagen-alpha 1(I) and -alpha 2(I) genes form the triple helical molecule collagen type I, which constitutes the major ECM protein in tissue fibrosis. The collagen-alpha 1(I) gene is mainly transcriptionally regulated, and its promoter activity depends on the interaction of the transcription factors NF-I and Sp1 with a tandem repeat of evolutionary conserved NF-I/Sp1 switch elements. An increased affinity of Sp1 to these elements has been observed in experimental liver fibrosis. Here, we demonstrate that the DNA binding drug mithramycin displays a high affinity binding to the GC-rich elements in the collagen-alpha 1(I) promoter as measured by DNAse I protection and gel retardation assays. Mithramycin interferes with Sp1 but not with NF-I binding to these sites. At a concentration of 100 nM, mithramycin efficiently reduces basal and TGF-beta-stimulated alpha 1(I) gene expression in human primary fibroblasts. The transcriptional activity and mRNA steady state levels of other genes, including the collagenase gene, as well as the growth rate of fibroblasts remained unchanged on exposure to this drug. Taken together, our results indicate that the transcriptional activity of the type I collagen gene highly depends on its GC-rich regulatory elements, and further, that these elements can be differentially blocked, thereby changing the balance between ECM structural and degrading gene activities in human fibroblasts.
6-[18F]fluoro-L-fucose: a possible tracer for assessing glycoconjugate synthesis in tumors with positron emission tomography. (1990)

The potential of 6-[18F]fluoro-L-fucose (6-[18F]FFuc) for assessing glycoconjugate synthesis in tumors with positron emission tomography (PET) was investigated. Using the tissue sampling method with five tumor models, different time-radioactivity profiles were found: a nearly constant level in Lewis lung carcinoma (3LL) and different clearance patterns in others. Rapid clearance in normal tissues resulted in preferable uptake ratios for tumor imaging of brain and pancreas. Metabolic studies and the L-fucose loading effects on the tissue uptake proved the tracer to be a biochemically active L-fucose analog. Imaging of the intracranial rat glioma and 3LL in lungs or hepatomas in mice by autoradiography (ARG) and intramuscular VX-2 carcinoma in rabbits by PET was demonstrated. Using double-radionuclide ARG, similar distribution images of 6-[18F]FFuc and 14C-L-fucose but different tumor-to-liver uptake ratios were found. A metastasis model seemed to show a higher uptake of both tracers as compared to a primary tumor model.
Variable Importance Clouds: A Way to Explore Variable Importance for the Set of Good Models (2019)

Variable importance is central to scientific studies, including the social sciences and causal inference, healthcare, and other domains. However, current notions of variable importance are often tied to a specific predictive model. This is problematic: what if there were multiple well-performing predictive models, and a specific variable is important to some of them and not to others? In that case, we may not be able to tell from a single well-performing model whether a variable is always important in predicting the outcome. Rather than depending on variable importance for a single predictive model, we would like to explore variable importance for all approximately-equally-accurate predictive models. This work introduces the concept of a variable importance cloud, which maps every variable to its importance for every good predictive model. We show properties of the variable importance cloud and draw connections to other areas of statistics. We introduce variable importance diagrams as a projection of the variable importance cloud into two dimensions for visualization purposes. Experiments with criminal justice, marketing data, and image classification tasks illustrate how variables can change dramatically in importance for approximately-equally-accurate predictive models
Resource-Efficient FPGA Architecture and Implementation of Hough Transform (2011)

Hough transform is widely used for detecting straight lines in an image, but it involves huge computations. For embedded application, field-programmable gate arrays are one of the most used hardware accelerators to achieve real-time implementation of Hough transform. In this paper, we present a resource-efficient architecture and implementation of Hough transform on an FPGA. The incrementing property of Hough transform is described and used to reduce the resource requirement. In order to facilitate parallelism, we divide the image into blocks and apply the incrementing property to pixels within a block and between blocks. Moreover, the locality of Hough transform is analyzed to reduce the memory access. The proposed architecture is implement on an Altera EP2S180F1508C3 device and can operate at a maximum frequency of 200 MHz. It could compute the Hough transform of 512 × 512 test images with 180 orientations in 2.07-3.16 ms without using many FPGA resources (i.e., one could achieve the performance by adopting a low-cost low-end FPGA).
Iterative and adaptive slack allocation for performance-driven layout and FPGA routing (1992)

The authors gives a generalization, called the limit-bumping algorithm (LBA), of a procedure of H. Youssef et al. (1990) that transforms initial connection delays into upper limits on delay suitable for performance-driven layout. LBA is a simple way to distribute slacks using arbitrary allocation functions. It is shown that lower and upper bounds on connection delays can be used in the computation of upper limits for initial layout and for layout improvement. The methods have been integrated into a delay-sensitive router for field programmable gate arrays (FPGAs). In 22 standard benchmark designs, feasible system clock periods were reduced in every case by an average of 14% and as much as 32%. >
사무엘 존슨 비평의 대화적 상상력 - 음양의 원리와의 비교적 관점 - (1999)

해롤드 불룸은 「서구 정전」 (1994)에서 서구의 문학비평가로서 고대와 현대를 통틀어서 18세기 영국의 문인 사무엘 존슨(1709~1784)을 가장 정전적인 비평가로 들면서 `존슨 박사는 서구문학비평가들 중에서 가장 위대하며 그와 경쟁자를 찾는 것을 어려운 일이다.`라고 갈파한 바 있다. 존슨은 미셀 프코의 말을 빌리면 적어도 영미문학 비평분야의 `담론 실천의 창시자들`의 한 사람이 될수 있을 것이다. 푸코가 제시한 인물은 마르크스와 프로이트였다. 이들의 거대이론은 많은 추종자와 소학파를 만들어 냈다 이들은 `담론의 끊임없는 가능성`과 `다른 텍스트의 형성가능성과 법칙`을 만들어 냈다. 비평가로서 존슨이 다른 비평` 담론 실천의 창시자`가 될 수 있는 소이는 그의 거대한 실천비평의 현장에 나타나는 창조적인 모순과 생산적인 비일관성이 복합적이 조망들의 상호작용을 촉발하기 때문이다. 이러한 카니발적인 다성화 과정 속에서 간극, 부재, 열림, 절합, 모순, 종합 등의 활동이 일어날 수 있기 때문이다. 존슨은 비평에서 가장 기본적인 문제들인 ⑴ 언어와 문학비평과의 관계, ⑵ 서지와 `본문 비평`의 문제. ⑶ 신비평적인 `자세히 읽기` 방법 등을 진지하게 다루고 있다. 이러한 예비비평행위의 토대 위에서 존슨은 18세기 비평가답지 않게 놀라울만치 현대적인 조망속에서 비평작업을 수행했다. 존슨은 문학텍스트를 본체론적이거나 자족적인 객관적 대상으로만 생각하지 않고 작가, 독자, 사회, 문학, 관습 모두가 함께 문학작품의 의미와 기능을 창출해 내는 복잡한 의미 중첩과 상호성의 그물망을 가진 것으로 보았다. 그런데 이러한 복합적이고도 다원적인 비평태도는 필자가 보기에는 존슨의 인식론의 하부구조를 이루고 있는 `대화적 상상력`에 기인하는 것이다. 존슨은 모든 사물을 한면만을 부각시켜 보지 않고 `이미 언제나` 다충적인 구조 다시 말해 대화적인 상호침투적인 구조로 바라본다. 필자는 이 글에서 이러한 다원적인 비평태도를 그의 실제비평의 장에 산재해 있는 많은 예들 중에서 몇 개를 골라 제시하면서 증명해 보일려고 노력했다. 필자는 궁극적으로 존슨의 기본적인 비평 태도는 미하일 바호친의 `대화주의`와 연결되는 것으로 보았고 나아가 동북아시아의 집단무의식의 하나라고 볼 수 있는 `음양사상`과 연결해 보았다. 그러나 이 글에서 존슨 비평의 인식론적 토대를 `음양의 원리`로 파악하려는 비교문화적인 필자의 초보적인 시도는 앞으로 더 많은 검증과정이 필요할 것이다. 이러한 과정이 성공적으로 이루어진다면 존슨 비평은 동서를 아우르는 보편성을 획득하게 될 것이며, 명실공히 존슨은 문학비평의 세익스피어가 될 수 있을 것이다.
Synthesis and properties of anthracene containing polyethers (2000)

Four poly(oxymethyleneanthrylene)s were prepared by polycondensation of 9,10-diacetoxyanthracene (and a substituted analogue) with α,ω-dibromoalkanes. Two model compounds were also synthesized by the same procedure. Although non-conjugated the polymers could be doped with iodine. The redox reaction of doping was confirmed by the changes in the electronic and fluorescence spectra as well as by the appearance of paramagnetism and enhanced electrical conductivity. In comparison, the model compounds could not be doped. Doping with iodine occurs only when the polymers are in the solid state. This solid state polymer effect, reported also in previous publications, is explained by collective interactions of several anthracene units with the dopant.
Genetic diversity and phylogeny of toxic cyanobacteria determined by DNA polymorphisms within the phycocyanin locus (1995)

Cyanobacteria are a highly diverse group in relation to form, function, and habitat. Current cyanobacterial systematics relies on the observation of minor and plastic morphological characters. Accurate and reliable delineation of toxic and bloom-forming strains of cyanobacteria has not been possible by traditional methods. We have designed general primers to the phycocyanin operon (cpc gene) and developed a PCR which allows the amplification of a region of this gene, including a variable intergenic spacer sequence. Because of the specificity of this PCR for cyanobacterial isolates, the assay is appropriate for the rapid and reliable identification of strains in freshwater samples. Successive restriction endonuclease digestion of this amplification product, with a total of nine enzymes, yielded many identifying DNA profiles specific to the various taxonomic levels of cyanobacteria. The restriction enzyme profiles for MspI, RsaI, and TaqI were conserved for strains within each of the eight genera (40 strains) studied and clearly discriminated among these genera. Intrageneric delineation of strains was revealed by the enzymes AluI, CfoI, and HaeIII for members of the genus Microcystis, while strains of genus Anabaena were differentiated by the digestion patterns provided by AluI, CfoI, and ScrFI. Phenetic and cladistic analyses of the data were used to infer the genetic relatedness and evolution of toxic and bloom-forming cyanobacteria.

Formal-Analysis-Based Trace Computation for Post-Silicon Debug (2011)

This paper presents a post-silicon debug methodology that provides a means to rewind, or backspace, a chip from a known crash state using a combination of on-chip real-time data collection and off-chip formal analysis methods. A complete debug flow is presented that considers practical considerations such as area, on-chip non-determinism and signal propagation delay. This flow, along with a low-overhead breakpoint circuit, allows for state-accurate breakpointing capabilities without the need to monitor the entire state of the chip. The flow and associated hardware was tested using a hardware prototype, which consists of an OpenRISC processor instrumented with the debug hardware connected to a PC running the formal verification algorithms. Traces hundreds of cycles long were obtained using the methodology presented in this paper.
Evaluation of Oxygen Precipitated Silicon Crystals by Deep‐Level Photoluminescence at Room Temperature and Its Mapping (1992)

A deep‐level photoluminescence (PL), which corresponds to the D1 line (0.81 eV) at 4.2 K, is investigated at room temperature for oxygen precipitated Czochralski Si crystals in their growth directions. Analyses are made of the macroscopic and microscopic distributions of the room temperature D1 line intensity the room temperature band‐to‐band PL intensity , carrier lifetime (γ), and precipitated oxygen concentration . The relative concentration distribution of the D1 line deep‐level, which is represented by distribution of , is shown to be conveniently expressed by the distribution of with a value of between 0.5 and 1. From the distributions of and , we find that the deep‐level concentration of the D1 line increases (decreases) as the precipitated oxygen concentration increases (decreases) with close proportional correlation in their spatial distributions.
Feedlot and Carcass Grade Characteristics of Steers and Heifers as Influenced by Days on Feed (1970)

Feedlot growth characteristics and carcass grade factors of 100 Hereford steers and 100 Hereford heifers were evaluated at 30-day intervals over a 270-day feeding period. Average daily gain increased with increasing time on feed up to 180 days. Average daily gains were lower for heifers than for steers, but were not significantly different. Dressing percent for steers and heifers was similar within treatments. Marbling score and carcass grade increased significantly up to 240 days on feed. Steers reached any given grade 30 to 60 days earlier than heifers even though intramuscular fat deposition was similar between the sexes. The data indicated that steers and heifers deposited intramuscular fat at a similar rate, and that the deposition of intramuscular fat is not a continuous process but proceeds in a step-wise pattern at 60 to 90-days intervals.
Quantitative Trait Loci for Fusarium Head Blight Resistance in Barley Detected in a Two-Rowed by Six-Rowed Population (2003)

Fusarium head blight (FHB) is a disease problem (primarily caused by Fusarium graminearum Schwabe) that affects the quality and yield of barley (Hordeum vulgare L.) grain. The objectives of this study were to identify the location of quantitative trait loci (QTL) for resistance to FHB in a two-rowed by six-rowed population, to examine the association of FHB resistance with heading date and the Vrs1 (two-rowed spike morphology) locus, to validate the location of the major FHB resistance QTL primarily detected in the field, and to identify simple sequence repeat (SSR) markers linked to the QTL for FHB resistance. We created a genetic map of 143 molcular markers from a population derived from the parents Fredrickson (two-rowed, moderately resistant) and Stander (six-rowed, susceptible). The Fredrickson/Stander population was evaluated in two field environments by a grain spawn inoculation method, two field environments by a spray inoculation, and two greenhouse environments. QTL analysis detected three distinct regions on chromosome 2(2H) associated with FHB resistance; two of these regions were also associated with resistance to deoxynivalenol (DON) accumulation. One FHB resistance QTL was also associated with heading date, while another FHB resistance QTL was found associated with the Vrs1 locus. The third FHB resistance QTL was detected only in the greenhouse, but was coincident with a QTL for resistance to DON accumulation in the field. All three QTL were detected in the greenhouse, indicating that this environment may be useful for selecting FHB resistant barley genotypes. SSR markers were identified that are linked with each QTL and could prove useful for marker-assisted trait manipulation. Finally, the two major QTL detected in the field were validated using an independent population with Fredrickson and Stander parents.

Ultralow Voltage Pressure Sensors Based on Organic FETs and Compressible Capacitors (2013)

A novel structure for the fabrication of organic pressure sensors is presented. It is based on a polydimethylsiloxane capacitor integrated with a floating-gate organic field-effect transistor (OFET) able to operate at ultralow voltages. The thin-film device, fabricated on a flexible substrate, is specifically conceived for tactile sensing. The main novelty of the working principle consists in the physical separation between the pressure-sensitive area and the active area of the OFET. The complete characterization of the device, in response to the application of different pressures, is provided.
Effects of Food Phytochemicals on Xenobiotic Metabolism and Tumorigenesis (1993)

Many food phytochemicals are known to affect the biotransformation of xenobiotics, and may influence the toxicity and carcinogenicity of environmental chemicals. In this article, some of the basic mechanisms of these actions are reviewed. Special attention is placed on studies with indoles, isothiocyanates, allium organosulfur compounds, flavonoids, phenolic acids, terpenoids, and psoralens. These compounds may alter the levels of phase I and phase II drug-metabolizing enzymes by affecting the transcriptional rates of their genes, the turnover rates of specific mRNAs or enzymes, or the enzyme activity by inhibitory or stimulatory actions. In many cases, the actions can be rather selective via their actions on specific enzymes, especially on the different forms of cytochrome P450 enzymes. The inhibitory actions of these phytochemicals against tumorigenesis have been studied extensively in animal models. The results help us to understand the possible beneficial or harmful effects of these compounds. Caution has to be applied when extrapolating the results to humans, however, because of species differences and the large doses used in animal studies.

Investigation of the Molecular Extraction Process in Single Subpicoliter Droplets Using a Near-Infrared Laser Raman Trapping System (2000)

The near-infrared (NIR) laser Raman trapping system was applied to study liquid-liquid extraction in a single droplet in a subpicoliter range. The system trapped a single subpicoliter toluene droplet in water using the NIR laser beam and provided time-dependent optical images of the droplet during liquid-liquid extraction. The size of the trapped droplet gradually increased afterp-nonylphenol solution was added in water. The Raman spectra of the droplet prove that the increase of the droplet size was caused by the absorption of p-nonylphenol from the water. The distribution coefficient of p-nonylphenol in the sub-picoliter droplet was much higher than that in bulk solution.

Variability of daughter root yield produced by directly planting sweetpotato was studied using typical strains belonging to direct-daughter type and indirect-daughter type, and the indirect-daughter type was considedered the most promising for direct planting because of its stable yield.
Visible‐Color‐Tunable Light‐Emitting Diodes (2011)

Visible-color-tunable light-emitting diodes (LEDs) with electroluminescent color that changes continuously from red to blue by adjusting the external electric bias are fabricated using multifacetted GaN nanorods with anisotropically formed 3D InGaN multiple-quantum wells. Monolithically integrated red, green, and blue LEDs on a single substrate, operating at a fixed drive current, are also demonstrated for inorganic full-color LED display applications.
Gordon-Haus jitter reduction in enhanced power soliton systems (2002)

We have shown that the Gordon-Haus timing jitter in an enhanced power soliton transmission system is substantially lower than in a conventional soliton transmission line with equal path-average dispersion. The ability to simultaneously increase receiver SNR and reduce timing jitter will allow significant increases in amplifier spacing for given combinations of bit rate and system length. Examples of the possibilities allowed by this technique are presented.
