GAS PERMEATION PROPERTIES OF ION-EXCHANGED LTA-TYPE ZEOLITE MEMBRANES (2001)

NaA-type zeolite membranes were prepared on a 1.7-mm i.d. porous α-alumina tube by repeating a hydrothermal reaction. The membranes, which were prepared by four repetitions, were ion-exchanged with Ca2+ and K+, and the permeation for single-component and mixed gases were investigated at 35°C. The NaA-type membrane showed a hydrogen permeance of (0.8–2.6) × 10−8 mol · m−2 s−1 Pa−1 and a hydrogen/n-butane ideal separation factor of 12–15. The permeability properties of the membrane for binary mixtures were dependent on the size of the permeating molecules and their adsorptivity to the zeolite. The KA-type zeolite membrane showed a higher ideal separation factor for a hydrogen/nitrogen system than did the NaA- and CaA-type zeolite membranes. The pores of the CaA-type zeolite membrane were larger than those in the NaA- and KA-type zeolite membranes, and showed higher permeances to n-butane and i-butane. All the zeolite membranes contained non-zeolitic pores, which decreased the selectivity of permeation.
Design of the Simulation-Based Vehicle Distribution Planning System for Logistics (1994)

Many vehicle routing methods have been suggested, which minimize the routing distances of vehicles to reduce the total transportation cost. But the more considerations the method takes, the higher complexites are involved in a large number of practical situations. The purpose of this paper is to develop a vehicle distribution planning system using heuristic algorithms and simulation techniques for home electronics companies. The vehicle distribution planning system developed by this study involves such complicated and stochastic conditions as one depot, multiple nodes(demand points), multiple vehicle types, multiple order items, and other many restrictions for operating vehicles. The proposed system is compared with the nearest neighbor method of the current system in terms of total logistics cost and driving time. This heuristics algorithm and simulation based distribution planning system is efficient in computational complexity, and give improved solutions with respect to the cost as well as the time. This method constructs a route with a minimum number of vehicles for a given demand.
Archaea: Essential inhabitants of the human digestive microbiota (2016)

Prokaryotes forming the domain of Archaea, named after their first discovery in extreme environments, are acknowledged but still neglected members of the human digestive tract microbiota. In this microbiota, cultured archaea comprise anaerobic methanogens: Methanobrevibacter smithii, Methanobrevibacter oralis, Methanobrevibacter massiliense, Methanosphaera stadtmanae, Methanobrevibacter arboriphilus, Methanobrevibacter millerae and Methanomassiliicoccus luminyensis; along with the non-methanogen halophilic Archaea Halopherax massiliense. Metagenomic analyses detected DNA sequences indicative of the presence of additional methanogenic and non-methanogenic halophilic Archaea in the human intestinal tract and oral cavity. Methanogens specifically metabolize hydrogen produced by anaerobic fermentation of carbohydrates into methane; further transforming heavy metals and metalloids into methylated derivatives, such as trimethylbismuth which is toxic for both human and bacterial cells. However, the role of Archaea as pathogens remains to be established. Future researches will aim to increase the repertoire of the human digestive tract Archaea and to understand their possible association with intestinal and extra-intestinal infections and diseases including weight regulation abnormalities.
Adaptive clipping technique for reducing PAPR on OFDM systems (2003)

This paper is concerned about peak-to-average power ratio (PAPR) reduction technique on orthogonal frequency division multiplexing (OFDM) systems. First, we analyze PAPR statistical characteristics with fast Fourier transform (FFT) size and modulation order on OFDM systems. The result is that PAPR statistical characteristic is almost same for any sufficiently large size of FFT (>64) and types of modulation schemes. Next, the bit error rate (BER) performance and the power spectral density (PSD) of OFDM systems over clipping ratio (CR) are studied and simulated. The result is that BER performance goes a little bad but PAPR reduction effect is very large. Finally, we propose adaptive clipping technique for PAPR reduction on OFDM systems by modulation order.
Automated Structure Elucidation of Organic Molecules from <sup>13</sup>C NMR Spectra Using Genetic Algorithms and Neural Networks (2001)

The automated structure elucidation of organic molecules from experimentally obtained properties is extended by an entirely new approach. A genetic algorithm is implemented that uses molecular constitution structures as individuals. With this approach, the structure of organic molecules can be optimized to meet experimental criteria, if in addition a fast and accurate method for the prediction of the used physical or chemical features is available. This is demonstrated using (13)C NMR spectrum as readily obtainable information. (13)C NMR chemical shift, intensity, and multiplicity information is available from (13)C NMR DEPT spectra. By means of artificial neural networks a fast and accurate method for calculating the (13)C NMR spectrum of the generated structures exists. The approach is limited by the size of the constitutional space that has to be searched and by the accuracy of the shift prediction for the unknown substance. The method is implemented and tested successfully for organic molecules with up to 20 non-hydrogen atoms.
Quantitative Analysis of Nail Polish Remover Using Nuclear Magnetic Resonance Spectroscopy Revisited (2008)

Substantial modifications are presented for a previously described experiment using nuclear magnetic resonance (NMR) spectroscopy to quantitatively determine analytes in commercial nail polish remover. The revised experiment is intended for a second- or third-year laboratory course in analytical chemistry and can be conducted for larger laboratory section enrollments. The experiment employs the standard addition method, places a strong emphasis on careful treatment of NMR data, and introduces elements of group learning where students critically interpret a relatively large set of data. NMR spectra are obtained from aqueous solution samples without any deuterium present for a lock signal, a technical feature of the experiment that might be of general interest to the undergraduate chemistry teaching community.
A Self-Consistent Charge Density-Functional Based Tight-Binding Scheme for Large Biomolecules (2000)

A common feature of traditional tight-binding (TB) methods is the non-self-consistent solution of the eigenvalue problem of a Hamiltonian operator, represented in a minimal basis set. These TB schemes have been applied mostly to solid state systems, containing atoms with similar electronegativities. Recently self-consistent TB schemes have been developed which now allow the treatment of systems where a redistribution of charges, and the related detailed charge balance between the atoms, become important as e.g. in biological systems. We discuss the application of such a method, a self-consistent charge density-functional based TB scheme (SCC-DFTB), to biological model compounds. We present recent extensions of the method: (i) The combination of the tight binding scheme with an empirical force field, that makes large scale simulations with several thousand atoms possible. (ii) An extension which allows a quantitative description of weak-bonding interactions in biological systems. The latter include an improved description of hydrogen bonding achieved by extending the basis set and improved molecular stacking interactions achieved by incorporating the dispersion contributions empirically. In applying the method, we present benchmarks for conformational energies, geometries and frequencies of small peptides and compare with ab initio and semiempirical quantum chemistry data. These developments provide a fast and reliable method, which can handle large scale quantum molecular dynamic simulations in biological systems.
Deep Disguised Faces Recognition (2018)

Recently, deep learning based approaches have yielded a significant improvement in face recognition in the wild. However," disguised face" recognition is still a challenging task that needs to be investigated, and the Disguised Faces in the Wild (DFW) competition is designed for this task. In this paper, we propose a two-stage training approach to utilize the small-scale training data provided by the DFW competition. Specifically, in the first stage, we train Deep Convolutional Neural Networks (DCNNs) for generic face recognition. In the second stage, we use Principal Components Analysis (PCA) based on the DFW training set to find the best transformation matrix for identity representation of disguised faces. We evaluate our model on the DFW testing dataset and it shows better performance over the state-of-the-art generic face recognition methods. It also achieves the best results on the DFW competition - Phase 1.
Heuristic method for evaluating COIL performance (1996)

A heuristic methodology is described that was developed to evaluate the chemical efficiency of high-power chemical oxygen iodine laser (COIL) devices and its application to the specific evaluation of the U.S. Air Force Phillips Laboratory's RotoCOIL laser. A heuristic equation that forms the basis of this methodology and describes the COIL energy flow, energy losses, and power extraction using measured data, code results, and empirical relations is presented. Using this equation and bounding values for some of its terms, it is shown that for the RotoCOIL performance data the experimentally measured average O 2 ( 1 Δ) yield of 0.40 is nearly 38% below that which would be consistent with the measured extraction power. By relating terms of the heuristic equation to performance of individual components of the COIL system, it is concluded that nearly 50% of the efficiency loss for the RotoCOIL laser derives from oxygen generator and delivery losses, whereas 15% is from nozzle inefficiencies and 11% from resonator losses.
Unequal error protection for H.26L video transmission (2003)

The network adaptation feature is left open in the previous video coding standards. Thus the quality of video sequences compressed by a video codec like the H.263 and MPEG family may fall dramatically when they are carried over error prone environments. This situation was well recognized and network friendliness of the video codec became one of the main goals of the H.26L on-going ITU-T video coding project. A new network abstraction layer (NAL) concept has been defined and integrated into the H.26L standard and it deals with special properties of the transmission environments. We present the NAL concept and related matters such as data partitioning, packetization and profiles. We suggest that the data partitioning feature with unequal error protection (UEP) should be employed for mobile video telephony applications. We present experimental results to support our suggestion.
C-terminal domain phosphatase-like family members (AtCPLs) differentially regulate <i>Arabidopsis thaliana</i> abiotic stress signaling, growth, and development (2002)

Cold, hyperosmolarity, and abscisic acid (ABA) signaling induce RD29A expression, which is an indicator of the plant stress adaptation response. Two nonallelic Arabidopsis thaliana (ecotype C24) T-DNA insertional mutations, cpl1 and cpl3, were identified based on hyperinduction of RD29A expression that was monitored by using the luciferase (LUC) reporter gene (RD29ALUC) imaging system. Genetic linkage analysis and complementation data established that the recessive cpl1 and cpl3 mutations are caused by T-DNA insertions in AtCPL1 (Arabidopsis C-terminal domain phosphatase-like) and AtCPL3, respectively. Gel assays using recombinant AtCPL1 and AtCPL3 detected innate phosphatase activity like other members of the phylogenetically conserved family that dephosphorylate the C-terminal domain of RNA polymerase II (RNAP II). cpl1 mutation causes RD29ALUC hyperexpression and transcript accumulation in response to cold, ABA, and NaCl treatments, whereas the cpl3 mutation mediates hyperresponsiveness only to ABA. Northern analysis confirmed that LUC transcript accumulation also occurs in response to these stimuli. cpl1 plants accumulate biomass more rapidly and exhibit delayed flowering relative to wild type whereas cpl3 plants grow more slowly and flower earlier than wild-type plants. Hence AtCPL1 and AtCPL3 are negative regulators of stress responsive gene transcription and modulators of growth and development. These results suggest that C-terminal domain phosphatase regulation of RNAP II phosphorylation status is a focal control point of complex processes like plant stress responses and development. AtCPL family members apparently have both unique and overlapping transcriptional regulatory functions that differentiate the signal output that determines the plant response.
Association of increased expression of macrophage elastase (matrix metalloproteinase 12) with rheumatoid arthritis (2004)

These results establish a possible mechanism by which macrophage-derived MMP-12 may play an important role in the destructive process in RA. Inhibition of MMP-12 may be a potential modality for the treatment of RA.

Examining the Role of Social Media Analytics in Providing Competitive Intelligence (2021)

This study examines the role of social media analytics (SMA) in providing competitive intelligence (CI). Building on CI theory, the data from qualitative semi-structured interviews with respondents belonging to social media, manufacturing, telecommunication, IT and service industries were analyzed using Nvivo coding and matrix queries. The results show that SMA provides an expanded CI beyond the previous limits of customers/markets and competitors, including insights on supply chains, costs and information-flow. Moreover, SMA-driven CI can provide visibility to supply chain uncertainties enabling improvements in demand planning and inventory management. SMA can provide CI about competitors’ strengths and weaknesses and customers’ dynamics; however, the bi-directional nature of CI could be determinantal if SM-linked customers are not educated/kept informed. Matrix query results illuminate the differences/similarities in respondents’ views. Academically, the study shows that SMA provides expanded CI to businesses beyond previously known scope of competitor analysis.
Unidirectional error detection, localization and correction for DRAMs: Application to on-line DRAM repair strategies (2011)

A novel family of codes for the detection, localization and correction of unidirectional errors for DRAMs in proposed. For DRAM memories, multi-bit soft and hard errors are a growing concern, as the cell sizes continue to decrease with aggressive scaling down. As a result, the classical error detection/correction codes become less efficient to deal with multiple errors in a single word [16]. Berger codes are effective in detecting 100% of the unidirectional errors, but introduce considerable delay and does not provide any error correction feature. In order to decrease the computing time of the code check bits and, at the same time, to provide the possibility to localize the segment(s) where single or multiple errors have occurred, a modification of the Berger code is proposed, called Carry Save K Berger code (CS-K Berger). Basically consists in using Carry Save representations of the partial additions of the word segments. The number of check bits increases as compared with Berger code and consequently the code redundancy overhead increases but the delay in computing the check bits and the corresponding checking is drastically reduced. In addition, some patterns of unidirectional errors become correctable. The proposed CS-K Berger codes for different values of K are analyzed for different word lengths. The hardware required for code generation and verification is discussed as well, as the possibility of using this code for word segment replacement in online applications of DRAMs.
Spontaneous generation of a biradical species of neocarzinostatin chromophore: role in DNA bulge-specific cleavage. (1994)

Detailed structure determination of the major and minor base-catalyzed degradation products of the chromophore of the enediyne anticancer antibiotic neocarzinostatin in the absence of DNA demonstrates that the enolate Michael addition reaction leading to a spirolactone cumulene intermediate is a spontaneous, stereoselective process. The implications of these findings for the mechanism of the thiol-independent, site-specific cleavage by the so-generated radical species of the drug at a DNA bulge are described.
Community Analysis of Chronic Wound Bacteria Using 16S rRNA Gene-Based Pyrosequencing: Impact of Diabetes and Antibiotics on Chronic Wound Microbiota (2009)

The 16S rRNA gene-based analyses revealed complex bacterial communities including anaerobic bacteria that may play causative roles in the non-healing state of some chronic wounds. Our data suggest that antimicrobial therapy alters community structure--reducing some bacteria while selecting for others.
The Institutional Memory Hypothesis and the Procyclicality of Bank Lending Behavior (2002)

Stylized facts suggest that bank lending behavior is highly procyclical. We offer a new hypothesis that may help explain why this occurs. The institutional memory hypothesis is driven by deterioration in the ability of loan officers over the bank's lending cycle that results in an easing of credit standards. This easing of standards may be compounded by simultaneous deterioration in the capacity of bank management to discipline its loan officers and reduction in the capacities of external stakeholders to discipline bank management. We test the empirical implications of this hypothesis using data from individual U.S. banks over the period 1980-2000. We employ over 200,000 observations on commercial loan growth measured at the bank level, over 2,000,000 observations on interest rate premiums on individual loans, and over 2,000 observations on credit standards and bank-level loan spreads from bank management survey responses. The empirical analysis provides support for the hypothesis.
Isolation and Taxonomical Characterization of Strain KM1-15 with Antibiotic Activity from Pine Mushroom (Tricholoma matsutake) Basal Soil (2008)

Two hundred and sixty-eight bacterial strains were isolated from pine mushroom (Tricholoma matsutake) basal soil. In the course of screening for antifungal activity against seven plant pathogenic fungi (Alternaria panax, Botrytis cinerea, Colletotrichum gloeosprioides, Fusarium oxysporum, Phytopthora capsici, Pythium ultimum, Rizoctonia solani) of isolates, strain KM1-15 showed strong antibiotic activity against Alternaria panax and Colletotrichum gloeosprioides. In determining its relationship on the basis of 16S rDNA sequence, KM1-15 strain was most closely related to Bacillus (AY904033) (99.62%). When assayed with the API 50CHE Kit, unlike Bacillus koguryoae, it is positive for utilization of L-arabinose, cellobiose, inulin, and D-turanose. Results of cellular fatty acid analysis showed that major cellular fatty acids were 15:0 anteiso (35.78%) and 17:0 anteiso (17.97%). In particular, hydroxyl fatty acids such as 13:0 iso 3-OH, 14:0 iso 3-OH, 15:0 iso 3-OH, and 17:0 iso 3-OH were only restricted to strain KM1-15. DNA G+C content was 43.7 mol% and quinone system was MK-7 (100%) in strain KM1-15.
