PAPR reduction by combining selected mapping and selected spreading code in MC-CDMA systems (2004)

MC-CDMA is currently being investigated by many researchers as a promising candidate for future generations of wireless systems due to robustness to frequency selective fading, high spectral efficiency, and higher flexibility. However, the main drawback is the high peak to average power ratio (PAPR). In this paper, a method has been proposed to reduce PAPR in synchronous downlink MC-CDMA through signal mapping and code selection. Simulation results show that PAPR can be reduced significantly proportional to an increase of the number of different phase sequences.

Self-crosslinking and cocrosslinking with nitrile rubber of poly(vinyl chloride) with pendentN,N-diethyldithiocarbamate group (2001)

In order to realize the self-crosslinking and cocrosslinking of poly(vinyl chloride) (PVC) with nitrile-butadiene rubber (NBR), PVC with pendent N,N-diethyldithiocarbamate groups (PVC-SR) was prepared from the reaction of PVC with sodium SR in butanone. The PVC-SR was self-crosslinked and the PVC-SR/NBR blend was cocrosslinked under heating at 170°C. The effect of the degree of functionality of PVC-SR on the torque, gel content, glass-transition temperature, and tensile properties was investigated. The results showed that the crosslinking reaction did not occur for PVC, NBR, or the PVC/NBR blend. Introducing the SR groups into PVC caused the crosslinking reaction to occur and the high gel contents of the crosslinked samples were obtained in 15 min. The degree of crosslinking increased with the degree of functionality of PVC-SR. The mechanism of the crosslinking reaction was discussed. © 2001 John Wiley & Sons, Inc.

<title>Network management in decentralized data fusion networks</title> (1994)

Network management concerns the ability of a network to sustain continued correct operation. What constitutes correct operation of a network is dependent on the nature and application of the system. A decentralized data fusion system consists of a network of sensor nodes, each capable of local fusion of sensor data. The decentralized estimation algorithms described here are constrained to operate on fully connected and tree connected topologies. Neither topology is practical, both are vulnerable to the loss of a single link. Decentralized estimation in fully connected systems exploits the fact that direct communication is possible between every pair of nodes. The loss of any link changes the pattern of communication upon which the estimation algorithm is based. In a tree connected system, the loss of a single link can divide the network in two, stopping network-wide communication altogether. Management must maintain a continued flow of information throughout the network and along the routes which provide for the best overall network performance. Reliable routing depends on the existence of a range of routes and the ability to switch routes when failures occur. Decentralized data fusion management necessitates that the routing system operates within the constraints imposed on the sensing network. A management system which reconciles the requirement for redundant routes with the need for the maintenance of valid topologies is described. Thus, we provide for continued communication and estimation in a changing topological environment.
A New Active Queue Management Scheme Based on Packet Loss Ratio (2006)

A new dynamic adaptive AQM (active queue management) scheme based on network loss ratio is proposed. The packet loss ratio of the early network is adopted to mark the arriving packet, and it is used as the early drop probability so that the probability can approach the loss ratio of current real network. By adjusting the drop probability adaptively, the length of buffer queues can be kept in a certain area. The simulation experiment results using NS software tool show that the scheme can flexibly control the length of queue and reduce the jitter of delay
Tankyrase Inhibitors Target YAP by Stabilizing Angiomotin Family Proteins (2015)

As the key effector in the Hippo pathway, YAP was identified as an oncoprotein whose expression is elevated in various human cancers. However, the development of potentially therapeutic compounds targeting YAP has been slow and limited. Here, we find that tankyrase inhibitors suppress YAP activity. This effect is mediated by anigomotin (AMOT) family proteins. Tankyrases associate with AMOT family proteins and promote their degradation through E3 ligase RNF146. By antagonizing tankyrase activity, tankyrase inhibitors stabilize AMOT family proteins, thereby suppressing YAP oncogenic functions. Together, our studies not only demonstrate the tankyrase-RNF146-AMOT axis as an upstream pathway regulating YAP but also reveal a therapeutic opportunity in targeting YAP for cancer treatment.
The influence of anion species on the toxicity of 1-alkyl-3-methylimidazolium ionic liquids observed in an (eco)toxicological test battery (2007)

To enlarge the restricted knowledge about the hazard potentials of ionic liquids to man and the environment we have concentrated on analysing systematically the anion effect of six different anion moieties (Cl–, BF4–, (CF3SO2)2N–, (CF3)2N–, octylsulfate and bis(1,2-benzenediolato)borate) and the influence of the side chain length at the cation on (eco)toxicity. For our investigations, we used the flexible (eco)toxicological test battery considering aquatical and terrestrial compartments as well as different trophic levels including enzymes (acetylcholinesterase), mammalian cells (IPC-81), luminescent marine bacteria (Vibrio fischeri), limnic unicellular green algae (Scenedesmus vacuolatus), wheat (Triticum aestivum), cress (Lepidium sativum), duckweed (Lemna minor) and a soil invertebrate (the spring tail Folsomia candida). In general, the side chain effect was found consistently in all used test systems from the molecular up to the organismic level. Such a consistent response of the different test systems could not be confirmed for the tested anion moieties. Furthermore, in most of the investigated test systems the anion effects are not as distinct as the demonstrated side chain length effect. Nevertheless, for (CF3SO2)2N– a clear (eco)toxicological hazard potential is evident. Thus, the strategy to check toxicities within a flexible (eco)toxicological test battery has been proven to be effective for uncovering hazard potentials of ionic liquids.
BizMap: A framework for mapping business applications to IT infrastructure (2015)

Large enterprises are confronted with an increased need to fully understand the IT systems that support their business applications. Unfortunately, conventional communication trace-based approaches to discovering IT infrastructure dependencies are insufficient to gain a comprehensive mapping of business applications to IT infrastructure. This paper describes BizMap, a novel, information-discovery-based approach for deriving accurate business application topologies. BizMap uses a combination of information management, data analysis, and interactive visualization techniques to rapidly develop accurate topology models based on discovered information and configuration experts' insight. BizMap's evaluation is based on a comparison of the topologies created by BizMap's automated topology discovery with manually derived topologies with respect to performance and accuracy. It also includes a discussion of the user validation of the interactive BizMap steps.
Quality Improvement of Pyrolysis Liquid:  Effect of Light Volatiles on the Stability of Pyrolysis Liquids (2005)

The concentration method was developed for improving the storage stability of pyrolysis liquids without significantly decreasing the flash point of the liquid. This method, by which most of the water and part of the light reactive volatiles of fast pyrolysis liquid are replaced by alcohol, proved in laboratory-scale experiments to possess excellent potential to produce a high-quality (homogeneous, viscosity similar to light fuel oil, stable) liquid product, remove the unpleasant odor of pyrolysis, remove a part of the acidic content, and increase the heating value of the liquid by removing water. Preliminary tests at our companies' process development unit PDU-scale pyrolyser (20 kg/h) showed that similar product upgrading could also be achieved on a larger scale. The kinds of compounds removed were similar. The condenser temperature was optimized to 50 ± 4 °C. Within these conditions, up to 23 wt % of the feed and pyrolysis water can be eliminated from the condensers. This fraction, which can contain up to 9 wt % of the organic yield, can be used for process heat. An overall liquid recovery of 44.3 wt % (compared to typical 48.9 wt %) and a pyrolysis water yield of 9.9 wt % (compared to typical 12 wt %) were measured for dry forest-residue feedstock.
S-sequence encoded synthetic aperture B-scan ultrasound imaging (2013)

Traditional synthetic aperture ultrasound scanning involves firing on one element and receiving on all elements of an array, then firing another transmit element and receiving on all elements until all transmit-receive element pairs have been sampled. It offers excellent resolution but at the expense of signal-to-noise. To remedy this difficulty we propose an aperture encoding scheme that involves firing on multiple elements sampled from a Hadamard S-matrix, then applying matrix inversion methods to decouple signals to recover the effective synthetic aperture imaging set for subsequent image reconstruction. Because more than one elements are fired at a time, signal-to-noise is improved.
On the use of beamforming for estimation of spatially distributed signals (2004)

In wireless communications, spatially distributed signals originate from local scattering around the transmitter. Spatially distributed signals cause conventional high-resolution methods to show degradation in performance, since the underlying data model is of full rank theoretically. In this paper, a relationship between the distribution of the spatial spread and the power azimuth spectrum is derived. Using this relationship, two simple and robust estimators based on the conventional beamformer and Capon's beamformer for estimation of the nominal direction and spatial spread are found. The proposed estimators show very good performance in numerical examples.
SYNTHESIS OF ALKYL HYDROGEN ALKYLPHOSPHONATES (1999)

Abstract The synthesis of alkyl hydrogen alkylphosphonates 1 was studied. Different synthetic routes were investigated and it was found that alkylphosphonic anhydrides can serve as ideal precursors for the synthesis of those half-acids. It was also shown that isopropyl phosphonic dichloride reacts in a unique fashion to produce alkyl hydrogen isopropylphosphonates in moderate yields.
Detection of circulating breast tumor cells by differential expression of marker genes. (2002)

Real-time PCR for the simultaneous expression of multiple cancer-specific genes may ensure the specificity required for the clinical application of mRNA expression-based assays for occult tumor cells.
Platinum Diffusion Barrier Breakdown in a-Si/Au Eutectic Wafer Bonding. (2012)

Eutectic bonding in semiconductor fabrication requires a large degree of control over the stoichiometry and precision film thickness of the bonding materials. To reduce the migration of the bonding layers, diffusion barriers are typically utilized. Here, we demonstrate that a widely utilized diffusion barrier, Pt, does not prevent migration of Si in Si/Au eutectic bonding. We observe that this barrier breaks down at approximately 375°C, above the Au-Si eutectic temperature (363°C), and encourages consumption of the silicon substrate leading to uncontrolled stoichiometry variations and creation of microvoids. This failure results in reductions of bond strength and hermeticity. As an alternative, silicon dioxide is observed to prevent the silicon diffusion and subsequent substrate loss.
High single-mode power conversion efficiency vertical-cavity top-surface-emitting lasers (1993)

We report advances in the power conversion (wall-plug) efficiency of vertical-cavity top-surface-emitting lasers. The devices were fabricated from molecular beam epitaxial layers using deep proton implants to define gain-guided lasers. The epitaxial structure included low resistance, piecewise linearly graded n-type and p-type mirrors, a triple In/sub 0.2/Ga/sub 0.8/As quantum-well active region, and a delta-doped contact layer. Power conversion efficiencies as high as 12.7% for continuous-wave single-mode operation were measured after several hours of device operation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Development of Water-Compatible Molecularly Imprinted Polymers Based on Functionalized β-Cyclodextrin for Controlled Release of Atropine (2020)

Herein, a novel method for molecularly imprinted polymers (MIPs) using methacrylic acid functionalized beta-cyclodextrin (MAA-β-CD) monomer is presented, which was designed as a potential water-compatible composite for the controlled release of atropine (ATP). The molecularly imprinted microspheres with pH-sensitive characteristics were fabricated using thermally-initiated precipitation polymerization, employing ATP as a template molecule. The effects of different compounds and concentrations of cross-linking agents were systematically investigated. Uniform microspheres were obtained when the ratio between ATP, MAA-β-CD, and trimethylolpropane trimethacrylate (TRIM) was 1:4:20 (mol/mol/mol) in polymerization system. The ATP loading equilibrium data was best suited to the Freundlich and Langmuir isotherm models. The <i>in vitro</i> drug release study was assessed under simulated oral administration conditions (pH 1.5 and 7.4). The potential usefulness of MIPs as drug delivery devices are much better than non-molecularly imprinted polymers (NIPs). The study shows that the prepared polymers are a pH stimuli-responsive system, which controlled the release of ATP, indicating the potential applications in the field of drug delivery.
Numerical taxonomy of <i>Nocardia</i> (1973)

One hundred and seventeen features each for 157 strains belonging to the species Nocardia asteroides, N. brasiliensis, N. caviae, N. madurae, N. pelletieri, and N. dassonvillei and Streptomyces somaliensis were studied. The data were subjected to computer analysis, which included calculating S-value matrix, link sort and clustering, feature frequency sort, and median organism calculation. Of the 157 strains studied, 96 strains formed seven distinct groups, whereas the other strains remained unclustered or presented irregular groupings. The seven groups represented N. asteroides (four groups), N. caviae, N. brasiliensis, and N. madurae. Group II of N. asteroides corresponds to N. farcinica group of Tsukamura. The results are discussed and compared with those of other workers.
Receptor-Mediated Uptake of Pepsin by Laryngeal Epithelial Cells (2007)

This is a novel finding that further defines the role and mechanism of pepsin-mediated injury in laryngopharyngeal reflux. The objective of ongoing research is to identify the receptor and investigate potential antagonists as a new therapeutic option for patients with reflux-attributed disease--in particular, those patients who have persistent symptoms despite acid suppression therapy.
Onion Trait Heritability and Response from Selection (2006)

Realized heritability estimates of bolting percentage, pink root and fusarium basal rot severities and incidences, and percentage of single-centered bulbs were estimated for half-sib families of an intermediate-day, open-pollinated onion ( Allium cepa L.) population using selection response analysis. Half-sib families were selected based upon an index that equally weighted bolting percentage, pink root and fusarium basal rot severities and incidences, percentage of single-centered bulbs, and bulb quality. Families were subjected to one cycle of half-sib family recurrent selection. Pink root and fusarium basal rot severity was reduced by 17% and 7%, respectively, with realized heritability estimates of 1.28 and 0.65, respectively. More progress for pink root severity was made than was selected. Disease incidence was reduced by 18% and 12%, respectively, with heritability estimates of 0.65 and 0.60, respectively. Very little progress was made for the percentage of single-centered bulbs and this was reflected in a heritability estimate of 0.17. Selection based upon multiple characters at the same time may reduce the effectiveness of making improvements in a single trait. However even with low to moderate heritability, improvements were made, and suggest that further improvements can be made through selection.
Polyanionic Carboxyethyl Peptide Nucleic Acids (ce-PNAs): Synthesis and DNA Binding (2015)

New polyanionic modifications of polyamide nucleic acid mimics were obtained. Thymine decamers were synthesized from respective chiral α- and γ-monomers, and their enantiomeric purity was assessed. Here, we present the decamer synthesis, purification and characterization by MALDI-TOF mass spectrometry and an investigation of the hybridization properties of the decamers. We show that the modified γ-S-carboxyethyl-T10 PNA forms a stable triplex with polyadenine DNA.
Iridium Oxohydroxide, a Significant Member in the Family of Iridium Oxides. Stoichiometry, Characterization, and Implications in Bioelectrodes (2012)

Iridium oxohydroxide thin coatings have been prepared by a dynamic oxidation electrodeposition method from complex oxalate solutions that induce template effects in the final coating at the nanoscale. The preparation method induces the formation of a oxohydroxide with reproducible stoichiometry and sponge-like quasiamorphous open structure, high ionic mobility, and significant behavior as compared with other reported iridium oxides as derived from X-ray diffraction, XPS, and TGA. Reproducible mixed valence states are also observed and a local rutile structure that allows ion exchange and facile redox changes. Rather significant is the large affinity for organic compounds observed and the behavior as substrate for cell culture, the best observed to date. Optimal cell response seems to be related to such open structure, which suggests this coating as ideal for devices implanted in the nervous system.

Endozepine stupor. Recurring stupor linked to endozepine-4 accumulation (1998)

Recurring stupor can be caused by repeated metabolic, toxic or structural brain disturbances. Recently, cases of recurring stupor, with fast EEG activity were shown to display increased endogenous benzodiazepine-like activity during the episodes of stupor. Patients with recurring stupor underwent extensive metabolic and toxicologic screening, EEG and brain imaging. Endozepines and exogenously administered benzodiazepines were assayed in plasma and CSF by means of mass spectrometry. Flumazenil, a benzodiazepine antagonist was administered and the behavioural and EEG responses monitored. Treatment with oral flumazenil was attempted in selected cases. Twenty patients were found with recurring stupor. Episodes had begun between ages 18 and 67 years, and in nine patients, had disappeared spontaneously after 4-6 years with symptoms. Stupor lasted hours or days. Onset of the episodes and frequency were unpredictable. Patients were normal between attacks. Stupor was characterized by initial drowsiness, staggering and behavioural changes, followed by deep sleep and spontaneous recovery with post-ictal amnesia. Biochemical screening and brain imaging were always normal. Ictal EEG showed fast background activity, and flumazenil transiently awoke the patients and normalized the EEG. In the nine cases examined, endozepine-4 levels were increased during the stupor. Oral flumazenil reduced the frequency of the attacks in three of these nine patients. Recurring episodes of stupor may be due to increased endozepine-4. We propose the term 'endozepine stupor' for such episodes. Endozepine-4 is an endogenous ligand for the benzodiazepine recognition site at the GABAA receptor, with unknown molecular structure.
