Inhaled lipid cisplatin (ILC) in the treatment of patients with relapsed/progressive osteosarcoma metastatic to the lung (2012)

ILC is well tolerated in heavily treated osteosarcoma patients and did not appear to have the typical toxicities associated with intravenous cisplatin. Three of eight patients with less bulky disease had sustained benefit. Further study of ILC is warranted.
Qualitative Research: Exploring New Frontiers (1997)

Qualitative research is an excellent strategy for exploring new areas of study. It is particularly appropriate for the field of gastroenterology nursing, a developing nursing specialty. In this article, the authors provide an introduction to qualitative research through a comparison of quantitative and qualitative perspectives, exploration of qualitative research designs, and discussion of qualitative analysis. Examples of qualitative research are used to illustrate the rich, vivid, and practical information gained using four different mehtodological approaches. Qualitative research topics appropriate for gastroenterology nurse researchers are suggested.
High-<i>T</i><sub>c</sub>Josephson junctions fabricated by focused ion beam direct milling (2012)

High-Tc Josephson junctions were successfully fabricated by focused ion beam (FIB) direct milling. The characteristics of the junction barrier were carefully controlled by tuning the thickness of the link region. The optimal remaining thickness for the YBCO is about 70–80 nm even though the YBCO thicknesses are different. The temperature-dependence of the critical current provides good evidence of the superconductor–normal–superconductor weak link of the junctions. Although the flux-flow behavior increasingly dominates at lower temperatures, the voltage–current shows resistively shunted junction-like characteristics at temperatures close to Tc. The Shapiro steps of a single junction irradiated with microwaves were measured, revealing strong Josephson effects in ion-damaged junctions. This method will be of great benefit to nanoSQUIDs for the detection of spin systems.
Plantazolicin, a Novel Microcin B17/Streptolysin S-Like Natural Product from <i>Bacillus amyloliquefaciens</i> FZB42 (2010)

Here we report on a novel thiazole/oxazole-modified microcin (TOMM) from Bacillus amyloliquefaciens FZB42, a Gram-positive soil bacterium. This organism is well known for stimulating plant growth and biosynthesizing complex small molecules that suppress the growth of bacterial and fungal plant pathogens. Like microcin B17 and streptolysin S, the TOMM from B. amyloliquefaciens FZB42 undergoes extensive posttranslational modification to become a bioactive natural product. Our data show that the modified peptide bears a molecular mass of 1,335 Da and displays antibacterial activity toward closely related Gram-positive bacteria. A cluster of 12 genes that covers ∼10 kb is essential for the production, modification, export, and self-immunity of this natural product. We have named this compound plantazolicin (PZN), based on the association of several producing organisms with plants and the incorporation of azole heterocycles, which derive from Cys, Ser, and Thr residues of the precursor peptide.
Magnetic Shape Memory Polymers with Integrated Multifunctional Shape Manipulation (2019)

Shape-programmable soft materials that exhibit integrated multifunctional shape manipulations, including reprogrammable, untethered, fast, and reversible shape transformation and locking, are highly desirable for a plethora of applications, including soft robotics, morphing structures, and biomedical devices. Despite recent progress, it remains challenging to achieve multiple shape manipulations in one material system. Here, a novel magnetic shape memory polymer composite is reported to achieve this. The composite consists of two types of magnetic particles in an amorphous shape memory polymer matrix. The matrix softens via magnetic inductive heating of low-coercivity particles, and high-remanence particles with reprogrammable magnetization profiles drive the rapid and reversible shape change under actuation magnetic fields. Once cooled, the actuated shape can be locked. Additionally, varying the particle loadings for heating enables sequential actuation. The integrated multifunctional shape manipulations are further exploited for applications including soft magnetic grippers with large grabbing force, reconfigurable antennas, and sequential logic for computing.
Regional brain metabolic changes in patients with major depression treated with either paroxetine or interpersonal therapy: preliminary findings. (2001)

Subjects with MDD had regional brain metabolic abnormalities at baseline that tended to normalize with treatment. Regional metabolic changes appeared similar with the 2 forms of treatment. These results should be interpreted with caution because of study limitations (small sample size, lack of random assignment to treatment groups, and differential treatment response between treatment subgroups).
MWD can improve well safety, control (1988)

Measuring while drilling (MWD) can help improve well safety and at the same time reduce trouble and total drilling costs. Detection of geologically overpressured zones with the technique is now commonplace, but virtually no advance has been made in the art of detection of influx of formation fluids into the wellbore. This third of five articles in a series describes the most recently available MWD techniques of pressure prediction and discusses the need for influx detection and possible means for realizing this in the future.

Photoelectron microscopy with synchrotron radiation (1988)

Real-time images produced by photoelectrons from metal and semiconductor samples have been generated using synchrotron radiation. A single electrostatic objective lens coupled to a two-stage image intensifier has been used to evaluate the feasibility of combined imaging and spectroscopy with photoelectrons in the ultraviolet and soft x-ray regions. Images were generated using photon energies ranging from 9 to 160 eV. The use of monochromatic synchrotron radiation provides a unique capability for generating image contrast by digital subtraction of images formed with photon energies above and below a core-level binding energy. A simple electron-optical objective lens produces images with a few microns resolution, and adequate sensitivity to image 45-eV kinetic energy electrons using bending magnet radiation. Calculations based on these experiments show that comparable resolutions are possible for combined microscopy and spectroscopy with electrons of order 100-eV kinetic energy using currently available bending magnet synchrotron radiation. Calculations for expected performance from undulator sources are presented.
Towards high performance virtual routers on commodity hardware (2008)

Modern commodity hardware architectures, with their multiple multi-core CPUs and high-speed system interconnects, exhibit tremendous power. In this paper, we study performance limitations when building both software routers and software virtual routers on such systems. We show that the fundamental performance bottleneck is currently the memory system, and that through careful mapping of tasks to CPU cores, we can achieve forwarding rates of 7 million minimum-sized packets per second on mid-range server-class systems, thus demonstrating the viability of software routers. We also find that current virtualisation systems, when used to provide forwarding engine virtualisation, yield aggregate performance equivalent to that of a single software router, a tenfold improvement on current virtual router platform performance. Finally, we identify principles for the construction of high-performance software router systems on commodity hardware, including full router virtualisation support.
Dietary ether lipid incorporation into tissue plasmalogens of humans and rodents (1992)

Chronic feeding of 1-O-octadecyl-sn-glycerol (batyl alcohol) to patients suffering from congenital deficiency in tissue ether glycerolipids showed an increase in the plasmalogens content of their erythrocytes. However, nothing is known about the ether lipid content of other tissues in these patients. Feeding 1-O-heptadecyl-sn-glycerol to young rats showed that this uncommon ether lipid was incorporated to a high extent into the plasmalogens of all tissues except brain. Comparative studies with other precursors, such as 3-O-heptadecyl-sn-glycerol, heptadecanol and heptadecanoic acid, indicated a stereospecific incorporation of the dietary 1-O-alkyl-sn-glycerols into tissue plasmalogens without cleavage of the ether bond. Dietary ether lipids were also shown to be transferred from mothers to suckling rats, but not from pregnant rats to fetuses. The implication of these results to possible dietary ether lipid therapy for patients suffering from peroxisomal disorders is discussed.

<title>Augmented image histogram for image and video similarity search</title> (1998)

Image histogram is an image feature widely used in content- based image retrieval and video segmentation. It is simple to compute, yet very effective as a feature in detecting image-to-image similarity, or frame-to-frame dissimilarity. While the image histogram captures the global distribution of different intensities or colors well, it does not contain any information about the spatial distribution of pixels. In this paper, we propose to incorporate spatial information into the image histogram, by computing features from the spatial distance between pixels, belonging to the same intensity or color. In addition to the frequency, count of the intensity or color, the mean, variance, and entropy of the distances are computed to form an augmented image histogram. Using the new feature, we performed experiments on a set of color images and a color video sequence. Experimental results demonstrate that the augmented image histogram performs significantly better than the conventional color histogram, both in the image retrieval and video shot segmentation.
Comparison of methods for circulating cell-free DNA isolation using blood from cancer patients: impact on biomarker testing (2016)

Methods for isolation of cfDNA can affect DNA yield and molecular weight fractions recovery. These observations should be taken into account for cfDNA analysis in routine clinical practice.
A probabilistic model for measuring grammaticality and similarity of automatically generated paraphrases of predicate phrases (2008)

The most critical issue in generating and recognizing paraphrases is development of wide-coverage paraphrase knowledge. Previous work on paraphrase acquisition has collected lexicalized pairs of expressions; however, the results do not ensure full coverage of the various paraphrase phenomena. This paper focuses on productive paraphrases realized by general transformation patterns, and addresses the issues in generating instances of phrasal paraphrases with those patterns. Our probabilistic model computes how two phrases are likely to be correct paraphrases. The model consists of two components: (i) a structured N-gram language model that ensures grammaticality and (ii) a distributional similarity measure for estimating semantic equivalence and substitutability.
Synthesis, electrical properties, and nanocomposites of poly(3,4-ethylenedioxythiophene) nanorods (2010)

Cellulose nanofibers or “whiskers” derived from tunicates were coated with PEDOT:PSS to produce high-aspect-ratio nanorods with high electrical conductivity. Films made from these PEDOT:PSS whiskers have surface resistivities as low as 97 Ω/□. The nanorods were found to disperse well in polar organic solvents such as dimethylformamide, which allowed the fabrication of nanocomposites with inert host polymers such as poly(methyl methacrylate) and polystyrene. These materials display surface resistivities as low as 760 Ω/□. Due to the high aspect ratio of the PEDOT:PSS-coated whiskers (64) and the formation of well-dispersed whisker networks within the polymer matrices, these materials display a percolation threshold as low as ∼2% v/v. Using a sol–gel process, electrically conducting gels and aerogels with a density of 6.4 mg cm−3 and a surface resistivity of ∼200 kΩ/□ were also produced.
MEMS and Bio Nanotechnology (2005)

Besides rapid commercialization, MEMS is contributing to expand scientific frontiers in nano-scale and bio technology. This paper first discuses how to combine MEMS technologies with bottom-up nano technologies in order to establish the scientific foundation and to construct engineered nano systems. The following part deals with MEMS tools for nano science and a bio actuated MEMS device. A pair of probes with 10-50 nm tip radius were micromachined with integrated microactuators for adjusting the distance between tips in micrometer range. The device was applied to obtain nano tweezers that handle DNA molecules. DNA molecules were captured between tips by electric field and retrieved from solution. Mechanical stretching and the observation in electron microscopes were performed. For bio assay of enzymes, MEMS chips with fL-chambers were fabricated in which the enzymatic product of F1-ATPase was evaluated in a single molecular level. Correlation between its rotational motion and the number of synthesized/consumed ATP molecules was measured. In addition, a conveyance device driven by bio motor molecules (microtubules and kinesin) was demonstrated.
Bayesian methods for erasure insertion in frequency-hop communication systems with partial-band interference (1992)

The erasure of unreliable symbols improves the performance of most types of error-control coding if a good method is used to decide which symbols should be erased. Bayesian decision theory is employed to obtain such a method for use in frequency-hop communications with Reed-Solomon coding and errors-and-erasures decoding. The performance of frequency-hop communications with Bayesian erasure insertion is analyzed for channels with both partial-band and wideband Gaussian noise. The Bayesian technique is compared with Viterbi's ratio-threshold test, and these are compared to receivers that do not erase and use errors-only decoding. Comparisons are also made with receivers that erase all the symbols that are affected by the partial-band interference. When interference is strong, large coding gains result from the Bayesian method, and error probabilities are reduced by several orders of magnitude.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

On the use of averaging for the analysis of power electronic systems (1990)

Averaging theory as a rigorous framework for evaluating, refining, and extending heuristic averaged models now used in power electronics is introduced. It is shown that averaging theory provides direct techniques for recovering oscillatory effects such as ripple from the averaged model. As an application of the theory, examples of the analysis of simple DC-DC converters are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Queuine Micronutrient: Charting a Course from Microbe to Man (2015)

Micronutrients from the diet and gut microbiota are essential to human health and wellbeing. Arguably, among the most intriguing and enigmatic of these micronutrients is queuine, an elaborate 7-deazaguanine derivative made exclusively by eubacteria and salvaged by animal, plant and fungal species. In eubacteria and eukaryotes, queuine is found as the sugar nucleotide queuosine within the anticodon loop of transfer RNA isoacceptors for the amino acids tyrosine, asparagine, aspartic acid and histidine. The physiological requirement for the ancient queuine molecule and queuosine modified transfer RNA has been the subject of varied scientific interrogations for over four decades, establishing relationships to development, proliferation, metabolism, cancer, and tyrosine biosynthesis in eukaryotes and to invasion and proliferation in pathogenic bacteria, in addition to ribosomal frameshifting in viruses. These varied effects may be rationalized by an important, if ill-defined, contribution to protein translation or may manifest from other presently unidentified mechanisms. This article will examine the current understanding of queuine uptake, tRNA incorporation and salvage by eukaryotic organisms and consider some of the physiological consequence arising from deficiency in this elusive and lesser-recognized micronutrient.
Bearings and gears for advanced turbine engines and transmissions (1975)

The improved technology is discussed of engine main-shaft ball bearings, and spur gears in power transmission drive trains. Much of the technology can be applied to other ball and roller bearings, and to other spur and bevel gears throughout the engine, drive train, and accessory systems.
ETHNOPHARMACOLOGICAL STUDIES OF TRADITIONAL HEPATOP ROTECTIVE MEDICINAL PLANTS USED BY THE TRIBALS OF BILASPUR DISTRICTS (2011)

Plants play significant role not only in our econom y but also used as traditional medicines. Almost 75 % of the medicinally important plant species grow in wild co ndition. An ethnopharmacological survey was carried out to collect information on the use of plants for curing hepatic disorders. The majority of the remedies we re prepared from freshly collected plant material from the wild and from a single species only. They were mainly t aken orally, but some applications were prepared with a mixture of plants or ingredients such as honey, sugar, salt , ginger and pepper. A total of 45 hepatoprotective ethnopharmac ological plants species distributed in 32 families are documented in this study. The medicinal plants used by tribals are listed with botanical name, family, local name, parts used, mode of preparation and ethnopharmacological uses. Further studies on chemical and pharmacological
Cumulative Effect in Information Diffusion: Empirical Study on a Microblogging Network (2013)

Cumulative effect in social contagion underlies many studies on the spread of innovation, behavior, and influence. However, few large-scale empirical studies are conducted to validate the existence of cumulative effect in information diffusion on social networks. In this paper, using the population-scale dataset from the largest Chinese microblogging website, we conduct a comprehensive study on the cumulative effect in information diffusion. We base our study on the diffusion network of message, where nodes are the involved users and links characterize forwarding relationship among them. We find that multiple exposures to the same message indeed increase the possibility of forwarding it. However, additional exposures cannot further improve the chance of forwarding when the number of exposures crosses its peak at two. This finding questions the cumulative effect hypothesis in information diffusion. Furthermore, to clarify the forwarding preference among users, we investigate both structural motif in the diffusion network and temporal pattern in information diffusion process. Findings provide some insights for understanding the variation of message popularity and explain the characteristics of diffusion network.
Nontriggered magnetic resonance velocity measurement of the time‐average of pulsatile velocity (1993)

The feasibility of the determination of the time-average of pulsatile velocity obtained via a nontriggered magnetic resonance (MR) acquisition is studied. The advantage of this method, in comparison with a triggered acquisition, is a considerable reduction (approximately 15x) in acquisition time. However, pulsatility causes image artifacts, known as ghosts, and the Fourier transform technique required for the imaging procedure accomplishes time-averaging of the complex MR signal. Both effects can result in errors in the velocity determined. Calculations show that these errors depend on the velocity time function and the acquisition parameters. In vivo comparison of triggered and nontriggered MR velocity measurements in the femoral artery of volunteers (n = 7) shows larger statistical and systematic errors in the latter, which depend on the excitation angle. Therefore, this nontriggered average velocity measurement is only useful as a fast and rough estimation of the time-averaged velocity.
