Soluble polyimides containing alicyclic structures (1999)

Abstract A series of novel aromatic diamines containing kinked cycloalkane structures between two phenyl rings were synthesized by HCl‐catalyzed condensation reaction of excess aniline and corresponding cycloalkanone derivatives. The structures of the diamines were indentified by 1 H NMR, 13 C NMR, FT‐IR spectroscopy and elemental analysis. The polyimides were synthesized from the obtained diamines with various aromatic dianhydrides by one‐step polymerization in m ‐cresol. The polymerization was conducted for 6∼8 h with refluxing, which was enough to obtain the polymers with high molecular weight. The inherent viscosities of the resulting polyimides were in the range of 0.37∼1.66 dl/g. All polymers were readily soluble in common organic solvents such as chloroform, tetrachloroethane, dimethylacetamide, etc. and the glass transition temperatures were observed at 290 to 372°C. UV‐visible spectra were obtained to measure the transparency of polymer films. Most of the polymers showed high transmission above 90 % in the wavelength of 450 ∼ 600 nm.

EXAMEN HYDRAULIQUE DE L'ÉCOULEMENT DANS DES ROCHES CREVASSÉES SUR DES MODÈLES RÉDUITS (1963)

Résumé Dans ce compte rendu, l'auteur veut attirer l'attention sur le fait, que le phénomène souvent très compliqué des écoulements dans des systèmes de roches crevassés peut être examiné dans des laboratoires hydrauliques, quoique sous une forme idéalisée. Quelques exemples, tirés des examens actuellement déjà assez poussés, qui ont eu lieu dans le laboratoire hydraulique de la Chaire I d'Hydraulique à l'Université Technique du Bâtiment et des Transports de Budapest, illustrent les possibilités d'un élargissement ultérieur des examens en laboratoire. Le développement supplémentaire de la méthode expérimentale introduite (par exemple la mise au point d'un modèle spatial, à Budapest), pourrait encourager dans une mesure importante la solution de plus en plus exacte de nombreux problèmes de l'économie des eaux, et notamment les questions relatives aux écoulements dans des troches crevassées.
Direct CVD Growth of Graphene on Technologically Important Dielectric and Semiconducting Substrates (2018)

To fabricate graphene based electronic and optoelectronic devices, it is highly desirable to develop a variety of metal-catalyst free chemical vapor deposition (CVD) techniques for direct synthesis of graphene on dielectric and semiconducting substrates. This will help to avoid metallic impurities, high costs, time consuming processes, and defect-inducing graphene transfer processes. Direct CVD growth of graphene on dielectric substrates is usually difficult to accomplish due to their low surface energy. However, a low-temperature plasma enhanced CVD technique could help to solve this problem. Here, the recent progress of metal-catalyst free direct CVD growth of graphene on technologically important dielectric (SiO<sub>2</sub>, ZrO<sub>2</sub>, HfO<sub>2</sub>, h-BN, Al<sub>2</sub>O<sub>3</sub>, Si<sub>3</sub>N<sub>4,</sub> quartz, MgO, SrTiO<sub>3,</sub> TiO<sub>2</sub>, etc.) and semiconducting (Si, Ge, GaN, and SiC) substrates is reviewed. High and low temperature direct CVD growth of graphene on these substrates including growth mechanism and morphology is discussed. Detailed discussions are also presented for Si and Ge substrates, which are necessary for next generation graphene/Si/Ge based hybrid electronic devices. Finally, the technology development of the metal-catalyst free direct CVD growth of graphene on these substrates is concluded, with future outlooks.
Preliminary Studies on Triticale in Diets for Laying Hens (1973)

Five treatments including two levels of Triticale or wheat (50 and 100%) replacement of protein from milo were fed to laying hens. The results after 98 days indicated that egg production was significantly less when triticale or wheat replaced 100% of the milo protein. Egg weight was significantly less in all treatments in which triticale was used.
Approaching Charge Balance in Organic Light-Emitting Diodes by Tuning Charge Injection Barriers with Mixed Monolayers (2011)

Self-assembled monolayers (SAMs) of binary mixtures of 1-butylphosphonic acid and the trifluoromethyl-terminated analogue (4,4,4-trifluoro-1-butylphosphonic acid) were formed on ITO surfaces to tune the work function of ITO over a range of 5.0 to 5.75 eV by varying the mixing ratio of the two adsorbents. The mixed SAM-modified ITO surfaces were used as the anode in the fabrication of OLED devices with a configuration of ITO/SAM/HTL/Alq3/MX/Al, where HTL was the NPB or BPAPF hole-transporting layer and MX was the LiF or Cs(2)CO(3) injection layer. It was shown that, depending on the HTL or MX used, the maximum device current and the maximum luminance efficiency occurred with anodes of different modifications because of a shift in the point of hole/electron carrier balance. This provides information on the charge balance in the device and points to the direction to improve the performance.
Biotechnological valorization of biodiesel derived glycerol waste through production of single cell oil and citric acid by <i>Yarrowia lipolytica</i> (2009)

Abstract Continuous energy crises and increasing demand for conventional fuels has resulted in the need for biofuels on a commercial scale. Transesterification of oils to yield biodiesel – one of the principal biofuels currently produced in large‐scale operations – is coupled with significant production of a glycerol‐rich water (so‐called “crude” or “raw” glycerol), as an important side‐product of the process. The increasing demand for biodiesel leads to abundant quantities of this glycerol‐rich material on the market. Therefore, glycerol valorization has much to offer in the cost reduction of biodiesel production. To this end, various chemical or biotechnological strategies have been developed to obtain added‐value products using crude glycerol as substrate. This review combines an account of our attempts to achieve a biotechnological valorization of raw glycerol with a review of appropriate literature.

Electrical Resistivity of Ten Selected Binary Alloy Systems (1983)

This work compiles, reviews, and discusses the available data and information on the electrical resistivity of ten selected binary alloy systems and presents the recommended values resulting from critical evaluation, correlation, analysis, and synthesis of the available data and information. The ten binary alloy systems selected are the systems of aluminum–copper, aluminum–magnesium, copper–gold, copper–nickel, copper–palladium, copper–zinc, gold–palladium, gold–silver, iron–nickel, and silver–palladium. The recommended values for each of the ten binary alloy systems except three (aluminum–copper, aluminum–magnesium, and copper–zinc) are given for 27 compositions: 0 (pure element), 0.5, 1, 3, 5, 10(5)95, 97, 99, 99.5, and 100% (pure element). For aluminum–copper, aluminum–magnesium, and copper–zinc alloy systems, the recommended values are given for 26, 12, and 11 compositions, respectively. For most of the alloy systems the recommended values cover the temperature range from 1 K to the solidus temperature of the alloys or to about 1200 K. For most of the nine elements constituting the alloy systems, the recommended values cover the temperature range from 1 K to above the melting point into the molten state. The estimated uncertainties in most of the recommended values are about ±3% to ±5%. Key words: alloy systems; alloys; conductivity; critically evaluated data; data analysis; data compilation; data synthesis; electrical conductivity; electrical resistivity; metals; recommended values; resistivity.
Expression of retroviral genes in transgenic chickens. (1990)

The development of transgenic technology in poultry has lagged behind that in mammals because of the unique reproductive system of birds. Therefore, we chose to use wild-type and recombinant replication-competent avian leukosis viruses to determine whether these retroviruses could be artificially introduced into the germ line by injecting them near the blastoderm of fertile eggs just before incubation. We generated 23 proviral inserts that were stably inherited through two generations. Twenty-one inserts coded for complete avian leukosis virus. Two interesting inserts failed to produce complete virus. One coded for envelope glycoprotein only and the other coded for the group-specific antigen and envelope glycoprotein. Cell culture and animal studies showed that one of these inserts was very resistant to infection and oncogenesis by subgroup A field strains of avian leukosis virus. Therefore, this represents a model system for introducing genes from the pathogen into the host to induce host resistance to the pathogen. Future studies should be aimed at developing more efficient systems for introducing replication-defective retroviral vectors or cloned DNA into the germ line of poultry so that the regulation of gene expression can be studied and transgenic technology can be applied to the improvement of this highly reproductive group of farm animals.
Comparison of Cell Permeability of Cyclic Peptoids and Linear Peptoids (2018)

Cyclic peptoids are emerging as an attractive class of peptidomimetics. Compared to their linear counterparts, cyclic peptoids should have increased conformational rigidity and preorganized structures, enabling them to bind more tightly to target proteins without major entropy penalty. Because cyclic peptoids lack the amide protons in their backbones like linear peptoids, it is perceived that cyclic peptoids are seemingly cell permeable as much as linear peptoids. However, no systematic investigation for cell permeability of cyclic peptoids has been reported yet. Here, we, for the first time, demonstrate that cyclic peptoids are far more cell permeable than linear counterparts irrespective of their size and side chains. This study highlights that cyclic peptoids, along with combinatorial library and high-throughput screening technologies, will serve as a rich source of protein binding molecules, particularly targeting intracellular proteins, given their excellent cell permeability in addition to their conformational rigidity and proteolytic stability.

Assigning personality/identity to a chatting machine for coherent conversation generation (2017)

Endowing a chatbot with personality or an identity is quite challenging but critical to deliver more realistic and natural conversations. In this paper, we address the issue of generating responses that are coherent to a pre-specified agent profile. We design a model consisting of three modules: a profile detector to decide whether a post should be responded using the profile and which key should be addressed, a bidirectional decoder to generate responses forward and backward starting from a selected profile value, and a position detector that predicts a word position from which decoding should start given a selected profile value. We show that general conversation data from social media can be used to generate profile-coherent responses. Manual and automatic evaluation shows that our model can deliver more coherent, natural, and diversified responses.
Triaxial Modeling and Target Classification of Multichannel, Multicomponent EM Data for UXO Discrimination (2003)

Time-domain electromagnetic data collected for discrimination of unexploded ordnance (UXO) span one spatial component in one time gate to three spatial components and multiple time channels. The relative merits of additional temporal and spatial-component information were assessed by analyzing decimated data from the Geonics EM61-3D. The responses of 25 unique ordnance- and scrap-like objects buried in 45 depth-orientation states were modeled as triaxial time-dependent dipoles and were classified using the properties of the inferred model parameters. Performance was measured by the fraction of false positives for ordnance-like objects at 91% true positives. The best false-positive rate for the full multicomponent, multichannel data was 5%, which was achieved using the power-law slope of the time decay of the secondary-field EMF: ordnance-like items remain in “intermediate” time longer and display a characteristic −3∕2 slope, whereas scrap-like items (even those made of steel) transition to “late” time and the recovered power-law indices vary widely. However, this excellent performance is largely due to the fact that the ordnance-like objects are often larger than the scrap-like objects in this data set. Better generalization may be obtained with discriminants based solely on shape—ordnance-like objects are usually axisymmetric about a long axis—which yielded 32% false positives, again in the power-law slope. In contrast, the best false-positive rate for single-component, single-channel data was 68%. Other instrument configurations (single-component, multichannel or multicomponent, single channel) were generally ranked intermediately between these extremes. Additional experiments with intermediate numbers and positions of time gates revealed that the best discrimination is achieved when recording a broad time range for the secondary-field decay (&gt;10–20ms); the number or density of time gates has a smaller impact. These results demonstrate in an internally consistent way the significant performance improvement in UXO discrimination that can be achieved with multicomponent, multichannel electromagnetic sensors.
A Study on College Student's Understanding and Preference of Native Foods in Cheju-Do, Korea (1990)

The purpose of this study is (1) to develop native foods in the future continuosly, and (2) to provide basic information allowing college student's to correctly understand traditional culture, by investigating those college students' preference and understanding of the native foods in Cheju-do. To accomplish these purposes, the survey was carried out by use of questionaires for 344 residing in Cheju-do from 20th to 29th May, 1989. The statistical analysis including frequency, percentage, mean and standard deviation was performed by use of SAS program, while the significant difference between groups was examined by . The results of this study are summarized as follows : 1. It was showed that college man had higher understanding and preference of those native foods than college women. 2. The result relating to age indicated that the more the age, higher understanding and preference. 3. The result by residing areas showed that the college students in the rural area showed higher understanding and preference than students in the urban area. 4. Based on the educational background of those subjects' mothers, it was shown that those college students of mothers having lower educational background had higher understanding and preference of native foods. 5. Those college students having good understanding of native foods accounted for 63.4 percent, while students requiring the continued development of those native foods for 91.0 percent. As a consequence, it is apparent that most subjects tended to show the positive responses to those native foods.

Isolation and Culture of Adult Epithelial Stem Cells from Human Skin (2011)

The homeostasis of all self-renewing tissues is dependent on adult stem cells. As undifferentiated stem cells undergo asymmetric divisions, they generate daughter cells that retain the stem cell phenotype and transit-amplifying cells (TA cells) that migrate from the stem cell niche, undergo rapid proliferation and terminally differentiate to repopulate the tissue. Epithelial stem cells have been identified in the epidermis, hair follicle, and intestine as cells with a high in vitro proliferative potential and as slow-cycling label-retaining cells in vivo (1-3). Adult, tissue-specific stem cells are responsible for the regeneration of the tissues in which they reside during normal physiologic turnover as well as during times of stress (4-5). Moreover, stem cells are generally considered to be multi-potent, possessing the capacity to give rise to multiple cell types within the tissue (6). For example, rodent hair follicle stem cells can generate epidermis, sebaceous glands, and hair follicles (7-9). We have shown that stem cells from the human hair follicle bulge region exhibit multi-potentiality (10). Stem cells have become a valuable tool in biomedical research, due to their utility as an in vitro system for studying developmental biology, differentiation, tumorigenesis and for their possible therapeutic utility. It is likely that adult epithelial stem cells will be useful in the treatment of diseases such as ectodermal dysplasias, monilethrix, Netherton syndrome, Menkes disease, hereditary epidermolysis bullosa and alopecias (11-13). Additionally, other skin problems such as burn wounds, chronic wounds and ulcers will benefit from stem cell related therapies (14,15). Given the potential for reprogramming of adult cells into a pluripotent state (iPS cells)(16,17), the readily accessible and expandable adult stem cells in human skin may provide a valuable source of cells for induction and downstream therapy for a wide range of disease including diabetes and Parkinson's disease.

A P22 Scaffold Protein Mutation Increases the Robustness of Head Assembly in the Presence of Excess Portal Protein (2002)

Bacteriophage with linear, double-stranded DNA genomes package DNA into preassembled protein shells called procapsids. Located at one vertex in the procapsid is a portal complex composed of a ring of 12 subunits of portal protein. The portal complex serves as a docking site for the DNA packaging enzymes, a conduit for the passage of DNA, and a binding site for the phage tail. An excess of the P22 portal protein alters the assembly pathway of the procapsid, giving rise to defective procapsid-like particles and aberrant heads. In the present study, we report the isolation of escape mutant phage that are able to replicate more efficiently than wild-type phage in the presence of excess portal protein. The escape mutations all mapped to the same phage genome segment spanning the portal, scaffold, coat, and open reading frame 69 genes. The mutations present in five of the escape mutants were determined by DNA sequencing. Interestingly, each mutant contained the same mutation in the scaffold gene, which changes the glycine at position 287 to glutamate. This mutation alone conferred an escape phenotype, and the heads assembled by phage harboring only this mutation had reduced levels of portal protein and exhibited increased head assembly fidelity in the presence of excess portal protein. Because this mutation resides in a region of scaffold protein necessary for coat protein binding, these findings suggest that the P22 scaffold protein may define the portal vertices in an indirect manner, possibly by regulating the fidelity of coat protein polymerization.
Naturally occurring anticoagulants and bone marrow transplantation: plasma protein C predicts the development of venocclusive disease of the liver (1993)

Venocclusive disease (VOD) of the liver is the major dose-limiting complication of pretransplant regimens for bone marrow transplantation. Recent reports from different groups point to the involvement of the hemostatic mechanism in the development of VOD. We measured the naturally occurring anticoagulants protein C, antithrombin III, and protein S in 45 patients undergoing bone marrow transplantation for hematologic malignancies before cytoreductive therapy and after transplant. The aim of this prospective study was both to evaluate the status of the naturally occurring anticoagulant pathway in patients who develop VOD compared with patients who do not, and to find a predictive marker of VOD. In transplant patients, protein C decreased from before cytoreductive therapy to posttransplant, whereas protein S and antithrombin III did not. In a multivariate analysis, protein C was the only variable that could independently discriminate between VOD and non- VOD patients at all times. Discriminant function analysis established that low protein C levels before cytoreductive therapy predicted the occurrence of VOD with good sensitivity and specificity.
