Sarcophytolides G–L, New Biscembranoids from the Soft Coral Sarcophyton elegans (2013)

Abstract Six new biscembranoids, namely, sarcophytolides G–L ( 1 – 6 , resp.), together with six known analogs, were isolated from a marine soft coral Sarcophyton elegans. The structures of the new compounds were established on the basis of 1D‐ and 2D‐NMR (COSY, HSQC, HMBC, and NOESY) spectroscopic analysis together with the aid of MS, CD, and IR data. The unusual isobiscembranoid sarcophytolide G ( 1 ) was found for the first time in the genus Sarcophyton.
Friction-Spinning – Possibility of Grain Structure Adjustment (2017)

The friction spinning process is an innovative incremental forming technique that enables high degree forming operations in the field of tube and sheet metal forming. The integration of friction-sub-processes from friction welding into a metal spinning process permits the self-induced heat generation of the part. Compared with conventional spinning processes, this in-process heat treatment allows the extension of existing forming limits and also the production of more complex geometries from tubes and sheets. Additionally, the material/part properties like hardness, stress, grain structure/orientation, surface conditions etc. can be adjusted in a defined way during the forming process. This can be achieved through the use of appropriate process parameter settings in combination with the degree of deformation. The choice of feed rate, relative motion and friction coefficient gives rise to a defined temperature profile and allows the use of specific process control strategies to produce parts with different material properties in different areas. Thus, the production of a new class of individually adjustable components is enabled. For example, these parts could be designed for load optimized applications like complex hollow parts in aluminium or steel. This paper presents the results of the grain structure investigations and clarifies the influence of different process parameters in aluminium tube processing especially during flange forming operations. A flange will thus be formed from an aluminium tube and, using to further tool systems, the wall thickness of the flange can be adjusted in a defined manner. The paper addresses the influence of the significant process parameters (feed rate, rotation speed, temperature, wall thickness reduction and forming time) on the grain structure refine-ment during flange forming. In addition, the impact of the material properties (hardness, stress/strain behaviour) will be considered.
Elevated Antithyroid Peroxidase and Antinuclear Autoantibody Titers in Ménière’s Disease Patients: More than a Chance Association? (2009)

Based on our data we speculate that there is a more than a chance association between MD and 'autoimmunity', thus suggesting a hypothetical role of the immune system in MD pathogenesis. In other words, a pathogenetic role of an 'immune dysregulation' in MD patients can be hypothesized.
Fully Printed Separated Carbon Nanotube Thin Film Transistor Circuits and Its Application in Organic Light Emitting Diode Control (2011)

The advantages of printed electronics and semiconducting single-walled carbon nanotubes (SWCNTs) are combined for the first time for display electronics. Conductive silver ink and 98% semiconductive SWCNT solutions are used to print back-gated thin film transistors with high mobility, high on/off ratio, and high current carrying capacity. In addition, with printed polyethylenimine with LiClO4 as the gating material, fully printed top-gated devices have been made to work as excellent current switches for organic light emitting diodes (OLEDs). An OLED driving circuit composed of two top-gated fully printed transistors has been fabricated, and the successful control over external OLED is demonstrated. Our work demonstrates the significant potential of using printed carbon nanotube electronics for display backplane applications.
Experimentation in the low-density plume of a simulated electrothermal thruster for computer code validation (1993)

Pressures and flow angles are measured in the plume of a 20 deg half-angle, conical nozzle in vacuum with Pitot tubes and conical probes. The area of measurement in the plume ranges from the nozzle exit plane to 480 mm axially downstream and from the plume centerline to 60 mm radially. The nozzle has an exit-to-throat area ratio of 100:1 and a throat diameter of 3.2 mm. The nozzle flow exhausts to a vacuum of order 10(exp -2) Pa to simulate a resistojet (an electrothermal rocket of less than 1 N of thrust) operating in space. Experimental data are given for flows of nitrogen at 55 and 68 mg/s, stagnation temperatures between 695 and 921 K, and stagnation pressures ranging from 5600 to 7100 Pa. Data are also given for argon at a rate of 68 mg/s, a stagnation temperature of 648 K, and stagnation pressures of 4500, 4750, and 4770 Pa. Measurements in the nitrogen plume are compared with computational results from a direct-simulation Monte Carlo method.
Crystal structure and electrochemical properties of phosphosulphate NaFe2PO4(SO4)2 (2021)

NASICON-type NaFe2(PO4)(SO4)2 (NFPS) electrode material is successfully synthesized via a rheological route. DSC/TG analysis shows that it is thermally stable up to 760 °C. A carbon composite NFPS/C was obtained using ball milling. NFPS and NFPS/C were investigated as cathode and anode materials for sodium-ion batteries. Analysis of migration paths was performed by the Voronoi-Dirichlet partition technique to determine all possible Na + ion migration paths. The diffusion coefficient, estimated by GITT, is in the 10 -12 -10 -13 cm 2 ∙s -1 range, which corresponds to the fast Na + ion migration in the structure. According to calculations, NFPS is a wide band gap material, which indicates its poor electrical conductivity.
Robustness of CDMA power control against disturbances and time-delays (2004)

This paper studies the robustness of a gradient-type CDMA power control algorithm with respect to disturbances and time-delays. This problem is of practical importance because unmodeled secondary interference effects from neighboring cells play the role of disturbances, and propagation delays are ubiquitous in wireless data networks. We first show L/sub p/-stability, for p/spl isin/[1, /spl infin/], with respect to additive disturbances. Then, using the L/sub /spl infin// property and a loop transformation, we prove that global asymptotic stability is preserved for sufficiently small time-delays in forward and return channels. For larger delays, we achieve global asymptotic stability by scaling down the step-size in the gradient algorithm.
A new method for graph stream summarization based on both the structure and concepts (2019)

Abstract Graph datasets are common in many application domains and for which their graphs are usually massive. One solution to process such massive graphs is summarization. There are two kinds of graphs, stationary and stream. For stationary graphs, a number of summarization algorithms are available while for graph stream there is no a comprehensive summarization method that summarizes a graph stream based on the structure, vertex attributes or both with varying contributions. This is because of challenges of graph stream, which are volume of data and changing of data over time. In this paper, we propose a method based on sliding-window model for which summarizes a graph stream based on a combination of the structure and vertex attributes. We proposed a new structure for summary graphs and also proposed new methods for comparing two summary graphs. To the best of our knowledge, this is the first method that summarizes a graph stream based on both the structure and vertex attributes with varying contributions. Through extensive experiments on real dataset of Amazon co-purchasing products, we have demonstrated the performance of the proposed method.
A new mouthrinse combining zinc and chlorhexidine in low concentrations provides superior efficacy against halitosis compared to existing formulations: a double-blind clinical study. (2007)

A combination of Zn and CHX in low concentrations seems to be the most efficient way to remove the VSC that causes bad breath at present. Studies are underway to further explore the extraordinary efficacy of this combination (close to 100%), suggesting a specific mode of action and a synergistic effect of these two components.
Roughness-induced non-wetting (2000)

It is shown that a certain class of self-affine profiles of surface roughness may render any substrate with a non-zero microscopic contact angle non-wet, i.e., give it a macroscopic contact angle close to 180 degrees. This is in some contrast to previous work and not only of potential applicational interest, but may also contribute to the amazing water repellency of some plant leaves.
The Dark Menace (2015)

As the cloud computing market continues to grow, the cloud platform is becoming an attractive target for attackers to disrupt services and steal data, and to compromise resources to launch attacks. In this paper, using three months of NetFlow data in 2013 from a large cloud provider, we present the first large-scale characterization of inbound attacks towards the cloud and outbound attacks from the cloud. We investigate nine types of attacks ranging from network-level attacks such as DDoS to application-level attacks such as SQL injection and spam. Our analysis covers the complexity, intensity, duration, and distribution of these attacks, highlighting the key challenges in defending against attacks in the cloud. By characterizing the diversity of cloud attacks, we aim to motivate the research community towards improving future security solutions for cloud systems.
Reduction Fe[sup 3+] of Impurities in LiFePO[sub 4] from Pyrolysis of Organic Precursor Used for Carbon Deposition (2006)

The structural properties of microcrystalline LiFePO4 prepared with and without carbon coating are analyzed with X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, and magnetic measurements for comparison. While nanosized ferromagnetic particles (-Fe2O3 clusters) are evidenced from magnetic measurements in samples without carbon coating, such ferromagnetic clusters just do not exist in the carbon-coated sample. Ferromagnetic resonance experiments are a probe of the -Fe2O3 nanoparticles, and magnetization measurements as well, allowing for a quantitative estimate of the amount of Fe3+. While the fraction of iron in the Fe3+ configuration rises to 0.18% (in the form of -Fe2O3 nanoparticles) in the carbon-free sample, this fraction falls to a residual impurity concentration in the carbon-coated sample. Structural properties show that the carbon does not penetrate inside the LiFePO4 particles but has been very efficient in the reduction of Fe3+, preventing the -Fe2O3 clustering thus pointing out a gas phase reduction process. The carbon deposit characterized by Raman spectroscopy is an amorphous graphite deposit hydrogenated with a very small H/C ratio, with the same Raman characteristics as a-C carbon films obtained by pyrolysis technique at pyrolysis temperature 830±30°C. The impact of the carbon coating on the electrochemical properties is also reported.
Information Optimal Adaptive Measurement Design For Compressive Imaging (2013)

We design an adaptive compressive imager by maximizing mutual information between measurements and the object. Simulation result shows that the proposed design requires 1.5 times fewer measurements relative to a static information-optimal design.
Food Ingredient Encapsulation (1995)

Fluid Bed encapsulation has proven to be a viable method of coating solid particle food ingredients to allow their successful use in a number of key applications. When designing a custom encapsulated ingredient, one must first determine the desired release mechanism and a method for quality measurement. Then by manipulating a number of factors, including the shape and size of the substrate and key processing parameters, the optimum encapsulated ingredient can be produced.
A prototype MR insert PET detector with strip-line readout (2017)

We are developing a MR insert PET detector using SiPM for small animal imaging. Our detector design is based on the strip-line signal readout that we have developed to efficiently handle large amount signals for SiPM-based TOF PET. The stripline readout has an advantageous feature suitable for building PET integrated within MR. In strip-line readout, the signal digitization is accomplished remotely from the detection module, thereby the front-end electronics of the detector within MR is minimal; the interference between two systems, e.g., magnetic field distortion due to PET, can be minimized accordingly. The feasibility of the strip-line readout for PET/MR has been demonstrated in our previous study. The current prototype MR insert PET is comprised of 8 detector modules, which are installed in a plastic cylindrical supporting structure. Each detector module consists of 8x4 LYSO arrays (3x3x10 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> each) and two Hamamatsu S13361-3050NE-04 MPPC arrays (4x4, 3.2 mm pitch); 32 SiPM signals are routed in 4 strip-lines so that 8 LYSO/SiPM signals in a row are connected to each strip-line. The signals from strip-lines are fed to a 72-ch multi-voltage threshold (MVT) digitizer, which digitizes the input by TDCs implemented in FPGA. Experiments have been carried out to evaluate the detector performance, and image reconstruction also has been performed for a simple shape object. In the paper, the detail on the development of the MR insert PET are explained, and preliminary test results are presented.
Cross-layer QOS design: Overcoming QOS-unaware slot allocation (2008)

Layer 2 radio resource allocation schemes being used in mobile ad hoc networks (MANET) do not always take into account the Quality of Service (QoS) requirements of network traffic. As an example, the current USAP (Unifying Slot Assignment Protocol) slot allocation scheme is QoS-unaware. Consequently the scheme could grant available slots to lower priority traffic instead of higher priority traffic. This greatly reduces the effectiveness of QoS management schemes at other layers of the protocol stack (e.g. DiffServ at layer 3, and admission control at the application layer). We describe a cross-layer solution to this problem where a Local QoS Control (LQC) component is placed on every node. The LQCs on nodes in a channelized neighborhood share their per traffic class radio resource needs, enabling the LQC at each node to determine its urgency for additional slots comparing to that of other nodes in the neighborhood. Thus, in nodes that have a less urgent need for slots, the LQC can filter local application traffic to reduce the local demand for slots, which in turn helps those nodes with more urgent need to have a better chance securing additional slots. A description of the approach and a performance analysis is presented.
Phantom Ring‐Closing Condensation Polymerization: Towards Antibacterial Oligoguanidines (2011)

The first example of phantom ring-closing condensation polymerization for the synthesis of oligoguanidines is presented. A new oligoguanidine with a ring structure was achieved in one step by the condensation reaction of a triamine, like diethylenetriamine, with guanidine hydrochloride. The condensation reaction proceeded by selective ring-closure towards the formation of five-membered rings in the oligomer backbone. The resulting polymer repeat unit structure was different from the starting monomers (phantom polymer) and was formed by elimination of three molecules of ammonia per repeat unit. The inter-, intra-, and inter-molecular reaction sequences led to the new structure as proved by different spectroscopic techniques (atmospheric pressure chemical-ionization mass spectrometry, and one-dimensional and two-dimensional homo- and heteronuclear correlation NMR experiments) as well as supported by quantum chemical investigations. Preliminary results regarding antibacterial use of the resulting oligoguanidine were also promising and showed its effect within 15-30 min as an antibacterial material.
THE BEHAVIOUR AND MECHANISTIC DESIGN OF ASPHALT PAVEMENTS. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN (1987)

The mechanistic method of the design of asphalt pavements, as reported to the last Conference, has received a wide degree of acceptance by road authorities in South Africa. Additional work has enabled the application of the principles embodied in the method to lead to the development of more effective rehabilitation methods. This paper describes the importance of understanding the behaviour of asphalt pavements, with the emphasis on its state of distress. The importance of the type of support under the asphalt layer is emphasized, whether this be granular or cemented layers. Typical moduli for these layers in the distressed state is given for use in mechanistic rehabilitation methods. A variety of distress mechanisms is also discussed. The present state of the pavement can ge assessed more accurately and rehabilitation strategies better selected by using the methods and information discussed.
NMR Spectroscopic Characterization of Copper(II) and Zinc(II) Complexes of Indomethacin (2004)

Molecular diffusion constants were studied by NMR spectroscopy to provide information about the solution structures of a variety of Cu(II) and Zn(II) monomeric and dimeric complexes of indomethacin (IndoH). These studies showed that monomeric Zn(II)-Indo complexes substantially dimerize in DMF-d7 and DMSO-d6 solutions at room temperature, whereas the Cu(II) and Zn(II) dinuclear complexes remain largely intact in these solutions. There is evidence of an equilibrium between monomers and dimers for the Zn(II) complexes in solution, as shown by a reduced diffusion constant and lower average radius compared to the Cu(II) dimer. Such an equilibrium between monomers and dimers for the Zn(II) complexes is also consistent with previous results obtained from XAFS analysis of DMF solutions of such complexes. The greater lability and lower thermodynamic stability of the Zn(II) dimer complex compared to the Cu(II) analogue, as determined from the NMR experiments, is likely to result in the more ready release of free Indo in the GI tract. This is consistent with the previously observed higher GI toxicities of the Zn-Indo pharmaceutical preparations compared to the Cu(II)-Indo counterparts.
A 10 bit SAR ADC With Data-Dependent Energy Reduction Using LSB-First Successive Approximation (2014)

This paper presents a successive approximation (SA) algorithm called LSB-first SA and a corresponding 10 bit ADC implementation. The energy per conversion and number of bitcycles per conversion used by this algorithm both scale logarithmically with the activity of the input signal, such that an N-bit conversion uses between 2 and 2N+1 bitcycles, compared to N for conventional binary SA. This algorithm reduces ADC power consumption when sampling signals with low mean activity. The ADC is implemented in a 0.18 μm CMOS process. With a 0.6 V supply, the maximum sample rate, leakage power, and ENOB are 16 kHz, 0.58 nW, and 9.73 b, averaged over 10 test chips. The DNL and INL are bounded at 0.09 and 0.22 LSBs. Given a DC input, the ADC achieves its best-case FoM of 3.5 fJ/conversion-step. Given a fullscale Nyquist sinusoid input, the ADC has its worst-case FoM of 20 fJ/conversion-step. The supply voltage can be increased to 1.0 V to reach a sample rate of 450 kHz, or decreased to 0.5 V to achieve a 2.9-17 fJ/conversion-step FoM range.

Potentially important variables identified by transvaginal ultrasound- guided embryo transfer (1997)

Transvaginal ultrasound-guided embryo transfer was performed on 121 consecutive patients. Observation was made of guiding cannula and transfer catheter placement in relation to the endometrial surface and uterine fundus during embryo transfer. The position and movement of a transfer-associated air bubble and the impact of subendometrial myometrial contraction leading to endometrial movement was observed. Results indicate that tactile assessment of embryo transfer catheter placement is unreliable: in 17.4% of transfers the outer guiding catheter inadvertently abutted the fundal endometrium. The outer guiding cannula indented the endometrium in 24.8% and the transfer catheter embedded in the endometrium in 33.1%. Unavoidable sub-endometrial transfers occurred in 22.3% of transfers. Ultrasound-guided transfer avoided accidental tubal transfer in 7.4% of transfers. Transfer catheter withdrawal did not significantly affect embryo transfer-associated air bubble position. Endometrial movement due to sub-endometrial myometrial contraction was obvious in 36.4% of cases, with active motion of the transfer-associated air bubble occurring in 28.1%. Pregnancies occurred in 45.5% of transfers with endometrial movement compared to 15.6% (P < 0.001) without.
Competitive concurrent distributed queuing (2001)

Distributed queuing is a fundamental problem in distributed computing, arising in a variety of applications. The challenge in designing a distributed queuing algorithm is to minimize message traffic and delay.
Synthesis and Application of [18F]FDG-Maleimidehexyloxime ([18F]FDG-MHO): A [18F]FDG-Based Prosthetic Group for the Chemoselective 18F-Labeling of Peptides and Proteins (2008)

2-[(18)F]Fluoro-2-deoxy-D-glucose ([(18)F]FDG) as the most important PET radiotracer is available in almost every PET center. However, there are only very few examples using [(18)F]FDG as a building block for the synthesis of (18)F-labeled compounds. The present study describes the use of [(18)F]FDG as a building block for the synthesis of (18)F-labeled peptides and proteins. [(18)F]FDG was converted into [(18)F]FDG-maleimidehexyloxime ([(18)F]FDG-MHO), a novel [(18)F]FDG-based prosthetic group for the mild and thiol group-specific (18)F labeling of peptides and proteins. The reaction was performed at 100 degrees C for 15 min in a sealed vial containing [(18)F]FDG and N-(6-aminoxy-hexyl)maleimide in 80% ethanol. [(18)F]FDG-MHO was obtained in 45-69% radiochemical yield (based upon [(18)F]FDG) after HPLC purification in a total synthesis time of 45 min. Chemoselecetive conjugation of [(18)F]FDG-MHO to thiol groups was investigated by the reaction with the tripeptide glutathione (GSH) and the single cysteine containing protein annexin A5 (anxA5). Radiolabeled annexin A5 ([(18)F]FDG-MHO-anxA5) was obtained in 43-58% radiochemical yield (based upon [(18)F]FDG-MHO, n = 6), and [(18)F]FDG-MHO-anxA5 was used for a pilot small animal PET study to assess in vivo biodistribution and kinetics in a HT-29 murine xenograft model.
