Relationship between Appearance of Photosensitivity and Total Pheophorbide Level in Spirulina Powder (1995)

The relation between the appearance of photosensitivity and the level of total pheophorbide (the existing pheophorbide plus chlorophyllase activity) in spirulina, an edible alga, was investigated in rats. Three kinds of spirulina which contain 72, 92 and 151mg% respectively of total pheophorbide were tested in, three groups of Wistar-strain male rats, together with a control group, by feeding diet containing 10% of each spirulina to the test groups, and the regular diet to the control group for 10 days, and giving 4 hour of light exposure a day.No symptom of photosensitivity was observed even in the group given spirulina containing 151mg% of total pheophorbide, as well as chlorella products which are restricted by law to contain less than 160mg% of total pheophorbide. There was no difference among the groups including the control in body weight, or serum GOT, GTP, potassium or sodium level.
핵심표준기술의 기술이전사업화를 통한 기업성장 및 신산업 창출 사례연구 - 이니텍(주) ETRI 협력사례를 중심으로 - (2013)

In a turbulent environment, it is important for a firm to obtain competitiveness through acquiring new technologies and new knowledge. Many studies has shown that R&D has positive effects on innovation and performance. However, the limitation of resources and research personnel for SMEs leads to the needs of collaboration between government R&D and SMEs. The quantitative results of government R&D comes in the form of patents or publication of papers while the qualitative results comes in the form of commercialization (revenue increase or cost reduction) of the SMEs acquiring the technology through technology transfer. Korean government invested 16.9 Trillion Won in 2013 and achieved remarkable quantitative results but the qualitative results are still yet to be improved. The technology transfer rate in 2011 was 26.0% while the success rate of commercialization of the transferred technology is only 23.6%. Therefore it is meaningful to study the success factors of the technology commercialization in Korea. In this study, a case of technology commercialization between ETRI and Initech is studied. Initech was a venture firm which started in 1997 with 2 employees and after transfer of technology from ETRI in 1999, it has grown to a firm of 238 employees. In this study, Jolly`s commercialization model was used to analyze the success factors of the commercialization. It was shown that four main factors that leads to the success are (1) mobilizing interest and endorsement through customer oriented R&D by ETRI, (2) mobilizing resources for demonstration through systematic technology commercialization process by ETRI, (3) mobilizing market constitutents through government standardization that leads to the reliability of the participants, and (4) mobilizing complementary assets for delivery by management strategies of Initech.
In vivo <i>T</i><sub>1ρ</sub> mapping in cartilage using 3D magnetization‐prepared angle‐modulated partitioned <i>k</i>‐space spoiled gradient echo snapshots (3D MAPSS) (2008)

For T(1rho) quantification, a three-dimensional (3D) acquisition is desired to obtain high-resolution images. Current 3D methods that use steady-state spoiled gradient-echo (SPGR) imaging suffer from high SAR, low signal-to-noise ratio (SNR), and the need for retrospective correction of contaminating T(1) effects. In this study, a novel 3D acquisition scheme-magnetization-prepared angle-modulated partitioned-k-space SPGR snapshots (3D MAPSS)-was developed and used to obtain in vivo T(1rho) maps. Transient signal evolving towards the steady-state were acquired in an interleaved segmented elliptical centric phase encoding order immediately after a T(1rho) magnetization preparation sequence. RF cycling was applied to eliminate the adverse impact of longitudinal relaxation on quantitative accuracy. A variable flip angle train was designed to provide a flat signal response to eliminate the filtering effect in k-space caused by transient signal evolution. Experiments in phantoms agreed well with results from simulation. The T(1rho) values were 42.4 +/- 5.2 ms in overall cartilage of healthy volunteers. The average coefficient-of-variation (CV) of mean T(1rho) values (N = 4) for overall cartilage was 1.6%, with regional CV ranging from 1.7% to 8.7%. The fitting errors using MAPSS were significantly lower (P < 0.05) than those using sequences without RF cycling and variable flip angles.
The Design of Broadband, Volumetric NRI Media Using Multiconductor Transmission-Line Analysis (2010)

Multiconductor transmission-line (MTL) analysis is used to model a broadband, volumetric negative-refractive-index (NRI) medium. Equations for the two-dimensional dispersion characteristics and the Bloch impedance are derived using a simplified periodic MTL analysis that provides insight into the operation of the NRI structure, while still accounting for spatial dispersion. Equations for the resonant points of the NRI medium are also derived, including the magnetic and electric plasma frequencies and the low-frequency backward-wave cutoff. The nature of each resonant point is discussed as well. Finally, this paper presents the modeling of finite structures with rigorous MTL analysis. Using this method, the reflection and transmission coefficients for normal incidence on a four-cell slab of the NRI medium are calculated and compared to full-wave simulation.
Ribosomal Synthesis of an Amphotericin-B Inspired Macrocycle (2014)

Here we report in vitro ribosomal synthesis of a natural product-like macrocyclic peptide, inspired by the structure of amphotericin B (AmB), an amphiphilic and membrane-interacting antifungal natural product. This AmB-inspired macrocyclic peptide (AmP), one side of which is composed of hydrophobic terpene, and the other side comprises a peptidic chain, was synthesized utilizing flexizyme-assisted in vitro translation via an unusual but successful initiation with a D-cysteine derivative. The established method for the synthesis of AmPs is applicable to the generation of a diverse AmP library coupled with an in vitro display format, with the potential to lead to the discovery of artificial bioactive amphiphilic macrocycles.

Regulation of calcineurin by phosphorylation (1989)

The site in calcineurin, the Ca2+/calmodulin (CaM)-dependent protein phosphatase, which is phosphorylated by Ca2+/CaM-dependent protein kinase II (CaM-kinase II) has been identified. Analyses of 32P release from tryptic and cyanogen bromide peptides derived from [32P]calcineurin plus direct sequence determination established the site as -Arg-Val-Phe-Ser(PO4)-Val-Leu-Arg-, which conformed to the consensus phosphorylation sequence for CaM-kinase II (Arg-X-X-Ser/Thr-). This phosphorylation site is located at the C-terminal boundary of the putative CaM-binding domain in calcinerin (Kincaid, R. L., Nightingale, M. S., and Martin, B. M. (1988) Proc. Natl. Acad. Sci. U. S. A. 85, 8983-8987), thereby accounting for the observed inhibition of this phosphorylation when Ca2+/CaM is bound to calcineurin. Since the phosphorylation site sequence also contains elements of the specificity determinants for Ca2+/phospholipid-dependent protein kinase (protein kinase C) (basic residues both N-terminal and C-terminal to Ser/Thr), we tested calcineurin as a substrate for protein kinase C. Protein kinase C catalyzed rapid stoichiometric phosphorylation, and the characteristics of the reaction were the same as with CaM-kinase II: 1) the phosphorylation was blocked by binding of Ca2+/CaM to calcineurin; 2) phosphorylation partially inactivated calcineurin by increasing the Km (from 9.9 +/- 1.1 to 17.5 +/- 1.1 microM 32P-labeled myosin light chain); and 3) [32P]calcineurin exhibited very slow autodephosphorylation but was rapidly dephosphorylated by protein phosphatase IIA. Tryptic and thermolytic 32P-peptide mapping and sequential phosphoamino acid sequence analysis confirmed that protein kinase C and CaM-kinase II phosphorylated the same site.

A high-performance and low-noise cmos image sensor with an expanding photodiode under the isolation oxide (2006)

We've realized a 2.5-/spl mu/m square pixel with high saturation electron capacity and sensitivity, which realizes the low dark current as well as triple Qs value of the conventional STI, by expanding the buried photodiode under the isolation oxide, and the sensitivity gain will be 20% higher using the Cu process than is possible with the Al process.
Microwave Thermionic Electron Gun for Synchrotron Light Sources (2019)

Thermionic RF guns are the source of electrons used in many practical applications, such as drivers for synchrotron light sources, preferred for their compactness and efficiency. RadiaBeam Technologies has developed a new thermionic RF gun for the Advanced Photon Source at Argonne National Laboratory, which would offer substantial improvements in reliable operations with a robust interface between the thermionic cathode and the cavity, as well as better RF performance, compared to existing models. This improvement became possible by incorporating new pi-mode electromagnetic design, robust cavity back plate design, and a cooling system that will allow stable operation for up to 1 A of beam current and 100 Hz rep rate at 1.5 μs RF pulse length, and 70 MV/m peak on-axis field in the cavity. In this paper, we discuss the electromagnetic and engineering design of the cavity and provide the test results of the new gun.
Operational notation for the analysis and synthesis of optical data-processing systems (1966)

This paper describes an operational notation that characterizes basic optical elements as block diagrams and that, for bandlimited optical systems, gives results identical to those obtained by rigorous application of the Fresnel-Kirchhoff diffraction formula. In an analysis of a basic optical system in terms of this operational notation, it is shown how the system can perform either the imaging operation or the Fourier transform operation. Repeated application of this basic system results in cascaded systems that perform more complex operations.
Representation And Retrieval Of Symbolic Pictures Using Generalized 2D Strings (1989)

We present a methodology for pictorial database design, based upon a new spatial knowledge structure. This spatial knowledge structure consists of an image database, symbolic projections representing the spatial relations among objects or sub-objects in an image, and rules to derive complex spatial relations from the generalized 2D string representation of the symbolic projections. The most innovative aspect of this spatial knowledge structure is the use of symbolic projections to represent pictorial knowledge as generalized 2D strings. Since spatial knowledge is encoded into strings, inference rules can be applied for spatial reasoning.

Linear time bounds for median computations (1972)

New upper and lower bounds are presented for the maximum number of comparisons, f(i,n), required to select the i-th largest of n numbers. An upper bound is found, by an analysis of a new selection algorithm, to be a linear function of n:
Decreases in Ikaros activity correlate with blast crisis in patients with chronic myelogenous leukemia. (1999)

Gene targeting studies in mice have shown that the lack of Ikaros activity leads to T-cell hyperproliferation and T-cell neoplasia, establishing the Ikaros gene as a tumor suppressor gene in mice. This prompted us to investigate whether mutations in Ikaros play a role in human hematological malignancies. Reverse transcription-PCR was used to determine the relative expression levels of Ikaros isoforms in a panel of human leukemia/lymphoma cell lines and human bone marrow samples from patients with hematological malignancies. Among the cell lines examined, only BV-173, which was derived from a chronic myelogenous leukemia (CML) patient in lymphoid blast crisis, overexpressed the dominant-negative isoform, Ik-6. In 9 of 17 samples of patients in blast crisis of CML, Ikaros activity had been reduced either by drastically reducing mRNA expression (4 of 17) or by overexpressing the dominant-negative isoform Ik-6 (5 of 17). Significantly, expression of Ikaros isoforms seemed normal in chronic phase CML patients and patients with other hematological malignancies. In some cases, overexpression of the dominant-negative Ik-6 protein was confirmed by Western blot analysis, and Southern blot analysis indicated that decreases in Ikaros activity correlated with a mutation in the Ikaros locus. In summary, these findings suggest that a reduction of Ikaros activity may be an important step in the development of blast crisis in CML and provide further evidence that mutations that alter Ikaros expression may contribute to human hematological malignancies.
Mismatch effects in time-interleaved oversampling converters (2002)

Recently, a new architecture was proposed which utilizes the concept of time-interleaving in oversampling converters. Using this architecture, one is theoretically able to achieve higher resolutions by using an array of interconnected modulators without increasing the oversampling ratio or order of the modulators. Alternatively, the same resolution can be maintained with wider bandwidth input signals. This paper presents the first experimental results on this new family of modulators. As well, the practical issue of component mismatch for these converters are studied and some suggestions are made to alleviate the effects of this problem.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Ketal Cross-Linked Poly(ethylene glycol)-Poly(amino acid)s Copolymer Micelles for Efficient Intracellular Delivery of Doxorubicin (2011)

A biocompatible, robust polymer micelle bearing pH-hydrolyzable shell cross-links was developed for efficient intracellular delivery of doxorubicin (DOX). The rationally designed triblock copolymer of poly(ethylene glycol)-poly(L-aspartic acid)-poly(L-phenylalanine) (PEG-PAsp-PPhe) self-assembled to form polymer micelles with three distinct domains of the PEG outer corona, the PAsp middle shell, and the PPhe inner core. Shell cross-linking was performed by the reaction of ketal-containing cross-linkers with Asp moieties in the middle shells. The shell cross-linking did not change the micelle size and the spherical morphology. Fluorescence quenching experiments confirmed the formation of shell cross-linked diffusion barrier, as judged by the reduced Stern-Volmer quenching constant (K(SV)). Dynamic light scattering and fluorescence spectroscopy experiments showed that shell cross-linking improved the micellar physical stability even in the presence of micelle disrupting surfactants, sodium dodecyl sulfate (SDS). The hydrolysis kinetics study showed that the hydrolysis half-life (t(1/2)) of ketal cross-links was estimated to be 52 h at pH 7.4, whereas 0.7 h at pH 5.0, indicating the 74-fold faster hydrolysis at endosomal pH. Ketal cross-linked micelles showed the rapid DOX release at endosomal pH, compared to physiological pH. Confocal laser scanning microscopy (CLSM) showed that ketal cross-linked micelles were taken up by the MCF-7 breast cancer cells via endocytosis and transferred into endosomes to hydrolyze the cross-links by lowered pH and finally facilitate the DOX release to inhibit proliferation of cancer cells. This ketal cross-linked polymer micelle is promising for enhanced intracellular delivery efficiency of many hydrophobic anticancer drugs.
Distribution Characteristics of Dynamic Deflection Basins of Distressed Asphalt Pavements (2013)

The objective of this study was to discuss the distribution features of dynamic deflection basins of distressed asphalt pavements using the dynamic finite element method. Based on the results obtained by systematic analysis, the criteria used to filter the effective data of falling weight deflectometer (FWD) deflection basins were presented and also verified by in-situ project study. The results demonstrate that the crack width of 0.2 mm is a critical value to determine the existence of contact behavior between crack contact surfaces. The distribution characteristics of dynamic deflection basins display a tremendous difference between intact and cracked pavements. The established criteria, involving surface deflection and surface modulus indicators, are verified to be reasonable and viable for filtering the FWD testing technology.

Using Spectral Fingerprints to Improve Wireless Network Security (2008)

The proliferation of affordable RF communication devices has given every individual the capability to communicate voice and/or data worldwide. This has increased wireless user exposure and driven the need for improved security measures. While earlier works have primarily focused on detecting and mitigating spoofing at the MAC layer, there has been a shift toward providing protection at the PHY layer by exploiting RF characteristics that are difficult to mimic. This research investigates the use of RF "fingerprints" for classifying emissions by exploiting transient signal features to provide hardware-specific identification. Reliable transient detection is the most important step in the process and is addressed here using variance trajectory of instantaneous amplitude and instantaneous phase responses. Following transient detection performance characterization, power spectral density fingerprints are extracted and spectral correlation used for classification. For proof-of-concept demonstration, the overall detection and classification process is evaluated using experimentally collected 802.11a OFDM signals. Results show that amplitude-based transient detection is most effective. Classification performance is demonstrated using three devices with overall classification accuracy approaching 80% for 802.11a signals at SNRs greater than 6 dB.
Automatic test generation using checkpoint encoding and antirandom testing (2002)

The implementation of an efficient automatic test generation scheme for black box testing is discussed. It uses checkpoint encoding and antirandom testing schemes. Checkpoint encoding converts test generation to a binary problem. The checkpoints are selected as the boundary and illegal cases in addition to valid cases to probe the input space. Antirandom testing selects each test case such that it is as different as possible from all the previous tests. The implementation is illustrated using benchmark examples that have been used in the literature. Use of random testing both with checkpoint encoding and without is also reported. Comparison and evaluation of the effectiveness of these methods is also presented. Implications of the observations for larger software systems are noted. Overall, antirandom testing gives higher code coverage than encoding random testing, which gives higher code coverage than pure random testing.
