Decision-feedback blind adaptive multiuser detector for synchronous CDMA system (2000)

We develop a blind adaptive multiuser detector for synchronous code-division multiple access (CDMA) with a noise-whitening filter. The triangular structure of the noise-whitened model ensures complete resolution of detection ambiguities. To further improve the symbol error probability performance, we introduce decision feedback in our detector similar to the decorrelating derision-feedback detector (DDFD), thus forming the decision-feedback blind adaptive multiuser detector (DFBD). Simulations indicate that the performance of the DFBD is very close to that of the DDFD in additive white Gaussian noise (AWGN) channels. In Rician fading channels, the DFBD can track the slowly varying channels well and has a symbol error probability performance approaching that of the DDFD, which requires the knowledge of users' energies. The blind adaptive and decision-feedback blind adaptive multiuser detectors proposed here do not, however, require that knowledge.
Polyamidoamine (PAMAM) Dendrimer Conjugates of “Clickable” Agonists of the A 3 Adenosine Receptor and Coactivation of the P2Y 14 Receptor by a Tethered Nucleotide (2020)

We previously synthesized a series of potent and selective A3 adenosine receptor (AR) agonists (North-methanocarba nucleoside 5′-uronamides) containing dialkyne groups on extended adenine C2 substituents. We coupled the distal alkyne of a 2-octadiynyl nucleoside by Cu(I)-catalyzed “click” chemistry to azide-derivatized G4 (fourth-generation) PAMAM dendrimers to form triazoles. A3AR activation was preserved in these multivalent conjugates, which bound with apparent Ki 0.1–0.3 nM. They were substituted with nucleoside moieties, solely or in combination with water-solubilizing carboxylic acid groups derived from hexynoic acid. A comparison with various amide-linked dendrimers showed that triazole-linked conjugates displayed selectivity and enhanced A3AR affinity. We prepared a PAMAM dendrimer containing equiproportioned peripheral azido and amino groups for conjugation of multiple ligands. A bifunctional conjugate activated both A3 and P2Y14 receptors (via amide-linked uridine-5′-diphosphoglucuronic acid), with selectivity in comparison to other ARs and P2Y receptors. This is the first example of targeting two different GPCRs with the same dendrimer conjugate, which is intended for activation of heteromeric GPCR aggregates. Synergistic effects of activating multiple GPCRs with a single dendrimer conjugate might be useful in disease treatment.
Comparison of spin relaxation in the metal-hydrogen systemsZrNiHxandZrNiDx (2006)

Relaxation studies of the intermetallics ${\mathrm{ZrNiH}}_{x}$ and ${\mathrm{ZrNiD}}_{x}$ were performed using hydrogen and deuterium NMR in the $\ensuremath{\beta}\phantom{\rule{0.3em}{0ex}}(x\ensuremath{\simeq}0.85)$ and $\ensuremath{\gamma}$ phases ($x\ensuremath{\simeq}2.6$ and 3.0). Correlation times for atomic diffusion in the hydride were determined based on the temperature dependence of spin-lattice and spin-spin relaxation times. The hydrogen motion is shown to be thermally activated over the temperature range $300--550\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, and the activation energies for diffusion are determined. The deuterium NMR spectra exhibit incomplete line narrowing with temperature, indicating that the average electric field gradient is not zero when averaged over the deuterium atom sites of these noncubic unit cells. The temperatures of minima in ${T}_{1}$ and ${T}_{2}$ for the deuterides indicate that the motion rates are similar for the D and H systems. However, the activation energies taken from the temperature dependencies of the deuterides' ${T}_{1}$ and ${T}_{2}$ are much smaller than for the hydrides, indicating the deuteride relaxation rates have additional contributions. The spectrum of ${\mathrm{ZrNiD}}_{1.87}$ reveals a coexistence of two phases, in agreement with the phase diagram.
Real-time visualization of network attacks on high-speed links (2004)

This article shows that malicious traffic flows such as denial-of-service attacks and various scanning activities can be visualized in an intuitive manner. A simple but novel idea of plotting a packet using its source IP address, destination IP address, and the destination port in a 3-dimensional space graphically reveals ongoing attacks. Leveraging this property, combined with the fact that only three header fields per each packet need to be examined, a fast attack detection and classification algorithm can be devised.

Adiponectin Inhibits Superoxide Generation by Human Neutrophils (2006)

Adiponectin (Ad), a member of the adipocytokine family, has been reported to possess antiinflammatory properties. We investigated the effects of full-length human Ad (hAd) on phorbol 12-myristate 13-acetate (PMA)-induced O2-* generation by human neutrophils. hAd, even at the lowest tested concentration of 0.001 microg/ml, after 30-min pretreatment of cells, significantly inhibited O2-* generation by neutrophils stimulated with PMA (100 nM). However, no relation between the dose of hAd and extent of inhibition of PMA-induced O2-* generation was observed with increasing the concentration of hAd up to 1 microg/ml. hAd also significantly inhibited neutrophil O2-* generation stimulated by N-formyl-methionyl-leucyl-phenylalanine (100 microM) and diacylglycerol (500 nM), as well as the PMA-induced neutrophil nitroblue tetrazolium reduction and H2O2 formation. Pretreatment of neutrophils with pronase-digested hAd failed to inhibit the PMA-induced O2-* generation. For the first time, this study revealed that Ad inhibited O2-* generation by neutrophils, possibly through regulation of NADPH oxidase.

A constriction channel analysis of astrocytoma stiffness and disease progression (2021)

Studies have demonstrated that cancer cells tend to have reduced stiffness (Young's modulus) compared to their healthy counterparts. The mechanical properties of primary brain cancer cells, however, have remained largely unstudied. To investigate whether the stiffness of primary brain cancer cells decreases as malignancy increases, we used a microfluidic constriction channel device to deform healthy astrocytes and astrocytoma cells of grade II, III, and IV and measured the entry time, transit time, and elongation. Calculating cell stiffness directly from the experimental measurements is not possible. To overcome this challenge, finite element simulations of the cell entry into the constriction channel were used to train a neural network to calculate the stiffness of the analyzed cells based on their experimentally measured diameter, entry time, and elongation in the channel. Our study provides the first calculation of stiffness for grades II and III astrocytoma and is the first to apply a neural network analysis to determine cell mechanical properties from a constriction channel device. Our results suggest that the stiffness of astrocytoma cells is not well-correlated with the cell grade. Furthermore, while other non-central-nervous-system cell types typically show reduced stiffness of malignant cells, we found that most astrocytoma cell lines had increased stiffness compared to healthy astrocytes, with lower-grade astrocytoma having higher stiffness values than grade IV glioblastoma. Differences in nucleus-to-cytoplasm ratio only partly explain differences in stiffness values. Although our study does have limitations, our results do not show a strong correlation of stiffness with cell grade, suggesting that other factors may play important roles in determining the invasive capability of astrocytoma. Future studies are warranted to further elucidate the mechanical properties of astrocytoma across various pathological grades.

Flow Metering of Gases Using Ultrasonic Phased-Arrays at High Velocities (2019)

We present an ultrasonic transit-time gas flow meter (UFM) based on our 40 kHz 8×8 phased-array. Besides single element receivers, the UFM usesa waveguide-based phased-array with an inter-element spacing of half-lambda as sender, capable of electronic beam steering for an extra-large flow velocity range. The sound drift effect limits the measurement range of conventional UFMs, i.e. we compensate the sound-drift effect using beam steering. The UFM features a maximum measurable flow velocity up to 100 ms <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> . The flowmeter body is a fully 3D-printed pipe with a length of 800 mm and an inner diameter of 315 mm. The receivers are arranged at inclination angles of 45°. The flowmeter is tested on a test rig for ventilation fans according to ISO 5801:2017(E). At zero flow velocity, the SNR for the downstream receiver is 64.1 dB. Without compensation of the sound-drift effect, at the full flow velocity of 100 ms <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> , the SNR drops down to 18.0 dB (downstream). When the compensation is enabled, the SNR raises by 18.7 dB (downstream) at full flow velocity. These numbers proof that the usage of a phased-array in a UFM can significantly increase the maximum measurable flow velocity. Further advantages are the possibility of multi-path measurements for an improved meter factor, i.e. eccentric flow meter configurations.
Mutual storage mode ion/ion reactions in a hybrid linear ion trap (2004)

Ion/ion proton transfer reactions involving mutual storage of both ion polarities in a linear ion trap (LIT) that comprises part of a hybrid triple quadrupole/linear ion trap mass spectrometer have been effected. Mutual ion storage in the x- and y-dimensions arises from the normal operation of the oscillating quadrupole field of the quadrupole array, while storage in the z-dimension is enabled by applying unbalanced radio-frequency amplitudes to opposing sets of rods of the array. Efficient trapping (>90%) is achieved for thermalized ions over periods of several seconds. Reactions were demonstrated for multiply charged protein/peptide cations formed by electrospray with anions derived from glow discharge ionization of perfluoro(methyldecalin) (PMD) introduced from the side of the LIT rod array. Doubly and singly charged protein ions are readily formed via ion/ion reactions. The parameters that affect ion/ion reactions are discussed, including the degree of RF unbalance on the LIT rods, vacuum pressure, nature of the buffer gas, reaction time, anion abundance, and the low mass cutoff for ion/ion reaction. The present system has a demonstrated upper mass-to-charge ratio limit of at least 33,000. The system also has high flexibility with respect to defining MSn experiments involving both collision-induced dissociation (CID) and ion/ion reactions. Experiments are demonstrated involving beam-type CID in the pressurized collision quadrupole (Q2) followed by ion/ion reactions involving the product ions in the LIT. Ion parking experiments are also demonstrated using the mutual storage ion/ion reaction mode in the LIT, with a parking efficiency over 60%.

Polysaccharides from Acorus calamus L. rizomes stimulated the functional activity of tumorbearing mice's lymphnode cells, even after cytostatic immunodepression. Transplantation of untreated mice tumor cells with lymphnode cells from tumorbearing mice after polysaccharide therapy led to inhibition of lung Lewis carcinoma growth and metastasing
A Single Nucleotide Polymorphism in the E-cadherin Gene Promoter-160 is Not Associated with Risk of Korean Gastric Cancer (2003)

Recently, the -160 C/A polymorphism, located within the regulatory region of Ecadherin promoter, has been shown to influence E-cadherin transcription by altering transcription factor binding. We examined the effect of this polymorphism on risk of gastric cancer and on histological classification of intestinal- and diffuse-type gastric cancer in 146 normal healthy individuals and 292 Korean gastric cancer patients. Genomic DNA samples were examined by polymerase chain reaction (PCR)-single strand conformational polymorphism (SSCP)-sequencing and confirmed by restriction fragment length polymorphism (RFLP). Unexpectedly, there was no significant difference in the genotype frequencies of the polymorphism between normal control and gastric cancer patients (x(2) test, p=0.433). The estimated odd ratio of C/C to A/A genotype in gastric cancer cases was 1.07 (95% confidence interval, 0.396-2.870). We also found no evidence for differences in risk for the intestinal- and diffuse-type gastric cancer. These results suggest that the -160 C/A polymorphism of the E-cadherin has no direct effect on the risk of Korean gastric cancer development and on its histological classification.
On‐Chip Direct Laser Writing of PAN‐Based Carbon Supercapacitor Electrodes (2022)

The carbonization of polyacrylonitrile (PAN) by direct laser writing to produce microsupercapacitors directly on-chip is reported. The process is demonstrated by producing interdigitated carbon finger electrodes directly on a printed circuit board (PCB), which is then employed to characterize the supercapacitor electrodes. By varying the laser power, the process can be tuned from carbonization to material ablation. This allows to not only convert pristine PAN films into carbon electrodes, but also to pattern and cut away non-carbonized material to produce completely freestanding carbon electrodes. While the carbon electrodes adhere well to the printed circuit board, non-carbonized PAN is peeled off the substrate. Specific capacities as high as 260 µF cm⁻<sup>2</sup> are achieved in a supercapacitor with 16 fingers.
ENDOSCOPIC THORACIC SYMPATHECTOMY FOR PRIMARY PALMAR HYPERHIDROSIS: INTERMEDIATE TERM RESULTS (1999)

Towards location-aware mobile web browsers (2009)

Location Based Services (LBS) promise interesting business opportunities. Today, most LBS are either implemented in hardware devices, or downloaded and installed by mobile phone users as software applications. Both approaches lead to scattered markets and hinder standardization. This paper suggests an alternative approach, which is to enhance mobile web-browsers with location information and implement LBS at the server-side. We define the design space for the location enhanced mobile web and present an implementation of a location enhanced web browser for the currently predominant mobile phone operating system, i.e. Symbian S60.
SUITABILITY OF CHROMOGENIC SUBSTRATES FOR ALCALASE DETECTION FOR INCLUSION IN AN AEROSOL MONITORING SYSTEM (1996)

The suitability of several chromogenic substrates to detect Alcalase (Novo) and other protease enzymes in sensing devices was evaluated. The sensitivity of the substrates was evaluated from their Kcat values and their stability to spontaneous breakdown was determined over an 8-h period. p-Nitrophcnyl trimethylacetate showed reasonable sensitivity but was the least stable of the substrates. The other substrata were based on p-nitroanalide chromophores and were very stable. The substrate which showed the highest sensitivity to Akalase was N-succinyl-L-alanyl-L-alanyl-L-ananyl-p-nitroanilide (k3 = 50.25 μmol AU−1 min−1). This substrate was selected for an 8-h assay. Esperase (Novo) and Subtilisin Carlsberg were compared with Alcalase with the substrate p-nitrophenyl trimethylacetate. A further evaluation of N-succinyl-L-alanyl-L-alanyl-L-alanyl-p-nitroanilide was made by incubating this substrate with Alcalase over an 8-h period. There was a gradual reduction in the rate over the 8-h period but it is suggested that the enzyme-substrate reaction is sufficiently stable for incorporation in a sensor for long-term monitoring.

Visual responses of tsetse flies (Diptera: Glossinidae) to odour-baited targets (1993)

Abstract Field studies in Zimbabwe showed how targets 1 m tall and 25–400 cm wide, composed of vertical panels of visual material and net and baited with odours of acetone, 1-octen-3-ol, and phenols, could be refined for controlling Glossina morsitans morsitans Westwood and G. pallidipes Austen. Attraction from a distance was not affected by swivelling movement but improved several-fold as the width of visual panels increased from 25 to 200 cm. Blue or blue/black targets were about as effective as black for G. m. morsitans but slightly more effective for G. pallidipes . Fine and coarse net was unattractive at long range but the flies avoided coarse net when close. The percentage of tsetse alighting on visual panels before flying round increased up to several times when the panels were widened, and when non-shiny black replaced blue or shiny black, but the percentage of flies alighting before departure was not much affected expect by panel width, being near 0% at 25 cm and 85% at 2 m. Most tsetse alighted first near the centre of targets, especially where black contrasted with nearby blue. Studies of various fabrics and paints and of restricted deposition of insecticide suggested several disposable targets that could have the costs of materials and insecticide, with efficacy preserved for G. m. morsitans and increased by up to 50% for G. pallidipes .

The 19 Genomes of Drosophila: A BAC Library Resource for Genus-Wide and Genome-Scale Comparative Evolutionary Research (2011)

The genus Drosophila has been the subject of intense comparative phylogenomics characterization to provide insights into genome evolution under diverse biological and ecological contexts and to functionally annotate the Drosophila melanogaster genome, a model system for animal and insect genetics. Recent sequencing of 11 additional Drosophila species from various divergence points of the genus is a first step in this direction. However, to fully reap the benefits of this resource, the Drosophila community is faced with two critical needs: i.e., the expansion of genomic resources from a much broader range of phylogenetic diversity and the development of additional resources to aid in finishing the existing draft genomes. To address these needs, we report the first synthesis of a comprehensive set of bacterial artificial chromosome (BAC) resources for 19 Drosophila species from all three subgenera. Ten libraries were derived from the exact source used to generate 10 of the 12 draft genomes, while the rest were generated from a strategically selected set of species on the basis of salient ecological and life history features and their phylogenetic positions. The majority of the new species have at least one sequenced reference genome for immediate comparative benefit. This 19-BAC library set was rigorously characterized and shown to have large insert sizes (125-168 kb), low nonrecombinant clone content (0.3-5.3%), and deep coverage (9.1-42.9×). Further, we demonstrated the utility of this BAC resource for generating physical maps of targeted loci, refining draft sequence assemblies and identifying potential genomic rearrangements across the phylogeny.
Computing MIB views via delegated agents (2002)

Network management applications typically need to extract useful information from raw MIB data. At present, they must poll this data from embedded SNMP agents and compute the information of interest at a remote management platform. In a growing number of scenarios this is either impossible or impractical. This problem could be resolved if the application could execute computations at the agent that would generate and retrieve an atomic snapshot. We present several examples that illustrate the need for mechanisms to support effective MIB computations at element agents, and describe mechanisms to support MIB computations specified in a View Definition Language. View programs are dispatched to and executed at an SNMP agent environment, and their results are organized in SNMP MIBs. This approach enables managers to program agents, yet requires no changes to the SNMP protocol.
