Stimuli‐responsive reversible physical networks. II. Design and properties of homogeneous physical networks consisting of periodic copolymers synthesized by living cationic polymerization (2005)

Abstract The design and precision synthesis of physical networks consisting of copolymers with crystallizable pendant groups are described in this work. Amphiphilic periodic, statistical, and gradient copolymers consisting of octadecyl vinyl ether (ODVE) units were synthesized via living cationic polymerization. The synthesis involved the copolymerization of ODVE and 2‐methoxyethyl vinyl ether (hydrophilic) with an 1‐(isobutoxy)ethyl acetate [CH 3 CH(O i Bu)OCOCH 3 ]/Et 1.5 AlCl 1.5 initiating system in the presence of a weak Lewis base to yield copolymers with very narrow molecular weight distributions (weight‐average molecular weight/number‐average molecular weight ⋍ 1.2). All aqueous solutions of the copolymers behaved as a viscous liquid above 50 °C. When cooled below 25 °C, the solutions turned into transparent, transient physical gels (exhibiting terminal flow), regardless of the sequence distribution. Viscoelastic studies showed that a periodic copolymer gave a hard gel that was more brittle than the gels obtained from the corresponding statistical and gradient copolymers. This difference and the differences in the relaxation time and relaxation mode distribution of the copolymer gels were consistent with the sequence distributions of ODVE in the respective copolymers. These results indicate that the mechanical properties of a physical network can be controlled by the primary polymer structures. © 2005 Wiley Periodicals, Inc.

An Efficient Protocol for the Palladium‐Catalyzed Asymmetric Decarboxylative Allylic Alkylation Using Low Palladium Concentrations and a Palladium(II) Precatalyst (2015)

Enantioselective catalytic allylic alkylation for the synthesis of 2-alkyl-2-allylcycloalkanones and 3,3-disubstituted pyrrolidinones, piperidinones and piperazinones has been previously reported by our laboratory. The efficient construction of chiral all-carbon quaternary centers by allylic alkylation was previously achieved with a catalyst derived <i>in situ</i> from zero valent palladium sources and chiral phosphinooxazoline (PHOX) ligands. We now report an improved reaction protocol with broad applicability among different substrate classes in industry-compatible reaction media using loadings of palladium(II) acetate as low as 0.075 mol % and the readily available chiral PHOX ligands. The novel and highly efficient procedure enables facile scale-up of the reaction in an economical and sustainable fashion.
Pulmonary Perfusion Imaging: Acute Toxicity and Safety Factors as a Function of Particle Size (1978)

Microspheres of five sizes and of three different materials were used to estimate the safety factor in pulmonary perfusion scintigraphy as a function of particle size. Particle suspensions of varying concentrations were injected into the tail vein of unanesthetized albino CD rats and mice. The LD50 (24 hr) for rats was found to range from 154,000 to 705 particles per gram body weight as particle diameter ranged conversely from 13.5 to 90.7 µ. The slope of the survival curves for rats showed the minimum lethal dose (MLD) to be about 25% lower than the LD50. When extrapolated to the clinical situation, these data yield safety factors of 1,663 to 16,630 for injected doses of 1 million to 100,000 microspheres 28.0 µ in diameter. The safety factor drops dramatically to 36 with an injected dose of 1 million particles 90.7 µ in diameter.
Purification of Hydrogen Containing Carbon Dioxide Using Metal Hydride (2015)

In this work, the influence of carbon dioxide concentration in the hydrogen on metal hydride has been investigated. LmNi 4.73 Mn 0.12 Al 0.15 was employed as a sample material for its durability against inorganic compound and operating temperature and pressure. Mixture of hydrogen and carbon dioxide is supplied to the sample in a double-ended cylinder at a constant flow rate and a part of the supplied gas is released to avoid condensing of impurity at a smaller constant flow rate than inlet. The temperature is maintained at 30 °C. The experimental results show the sample is able to absorb hydrogen selectively at carbon dioxide concentrations less than 30 vol% and the mixture of the carbon dioxide concentration of 20 vol% is purified to less than 0.1%.

Design, Implementation, and Evaluation of a Hybrid DS/FFH Spread-Spectrum Radio Transceiver (2014)

In recent years there has been great interest in using hybrid spread-spectrum (HSS) techniques for commercial applications, particularly in the Smart Grid, in addition to their inherent uses in military communications. This is because HSS can accommodate high data rates with high link integrity, even in the presence of significant multipath effects and interfering signals. A highly useful form of this transmission technique for many types of command, control, and sensing applications is the specific code-related combination of standard direct-sequence modulation with "fast" frequency-hopping, denoted hybrid DS/FFH, wherein multiple frequency hops occur within a single data-bit time. In this paper, we present the efforts carried out at Oak Ridge National Laboratory toward exploring the design, implementation, and evaluation of a hybrid DS/FFH spread spectrum radio transceiver using a single Field Programmable Gate Array (FPGA). The FPGA allows the various subsystems to quickly communicate with each other and thereby maintain tight synchronization. We also investigate various hopping sequences against robustness to interference and jamming. Experimental results are presented that show the receiver sensitivity, radio data-rate/bit-error evaluations, and jamming and interference rejection capabilities of the implemented hybrid DS/FFH spread spectrum system under widely varying design parameters.
Radiological Protection in Fluoroscopically Guided Procedures Performed Outside the Imaging Department (2010)

An increasing number of medical specialists are using fluoroscopy outside imaging departments, but there has been general neglect of radiological protection coverage of fluoroscopy machines used outside imaging departments. Lack of radiological protection training of those working with fluoroscopy outside imaging departments can increase the radiation risk to workers and patients. Procedures such as endovascular aneurysm repair, renal angioplasty, iliac angioplasty, ureteric stent placement, therapeutic endoscopic retrograde cholangio-pancreatography,and bile duct stenting and drainage have the potential to impart skin doses exceeding Gy. Although tissue reactions among patients and workers from fluoroscopy procedures have, to date, only been reported in interventional radiology and cardiology,the level of fluoroscopy use outside imaging departments creates potential for such injuries.A brief account of the health effects of ionising radiation and protection principles is presented in Section 2. Section 3 deals with general aspects of the protection of workers and patients that are common to all, whereas specific aspects are covered in Section 4 for vascular surgery, urology, orthopaedic surgery, obstetrics and gynaecology,gastroenterology and hepatobiliary system, and anaesthetics and pain management.Although sentinel lymph node biopsy involves the use of radio-isotopic methods rather than fluoroscopy, performance of this procedure in operating theatres is covered in this report as it is unlikely that this topic will be addressed in another ICRP publication in coming years. Information on radiation dose levels to patients and workers, and dose management is presented for each speciality.
Production of Alkaline Enzymes by Alkalophilic Microorganisms (1971)

Bacillus No. A-40-2 isolated from soil produced an alkaline amylase in alkaline media. The characteristic point of this microorganism was especially good growth in alkaline media, and no growth was detected in neutral media such as nutrient broth. The alkaline amylase of Bacillus No. A-40-2 was purified by DEAE-cellulose and hydroxyl apatite columns. The amylase was most active at pH 10.5 and stable pH was about 8.5. Calcium ion was effective to stabilize the enzyme especially at high temperatures. The sedimentation constant was about 3.8 S and molecular weight estimated by the Sephadex gel-filtration method was about 70000. The enzyme was inactivated by urea, sodium laurylsulfate and sodium dodecylbenzene sulfonate. EDTA, PCMB and DFP did not show inhibitory effect. The enzyme hydrolyzed about 700 of starch and yielded glucose, maltose and maltotriose. If the enzyme is a single entity, this alkaline amylase is a type of saccharifying α-amylase.

A semi-graphical modeling framework for the automated analysis of networked systems security (2015)

The modeling and analysis of security properties in large and complex networked systems is more and more demanding for the availability of computer-assisted software tools able to help designers and engineers in describing and verifying their systems in an easy way. Indeed, on the one hand these tasks are usually cumbersome and error-prone when carried out manually, while on the other hand they have to be repeated during the whole system lifetime, starting with its conception and deployment and ending with the system final disposal. This paper presents a semi-automated framework which is conceived for the fine-grained description of networked systems from the security point of view. In particular, the paper shows how a simple graphical user interface allows the designer to largely ignore the syntax of the input language for the analysis tool and focus only on the implemented system characteristics.

Workflow Anomaly Detection with Graph Neural Networks (2022)

Reliable execution of scientific workflows is a fundamental concern in computational campaigns. Therefore, detecting and diagnosing anomalies are both important and challenging for workflow executions that span complex, distributed computing infrastructures. In this paper we model the scientific workflow as a directed acyclic graph and apply graph neural networks (GNNs) to identify the anomalies at both the workflow and individual job levels. In addition, we generalize our GNN model to take into account a set of workflows together for the anomaly detection task rather than a specific workflow. By taking advantage of learning the hidden representation, not only from the job features, but also from the topological information of the workflow, our GNN models demonstrate higher accuracy and better runtime efficiency when compared with conventional machine learning models and other convolutional neural network approaches.
Leu-M1--a marker for Reed-Sternberg cells in Hodgkin's disease. An immunoperoxidase study of paraffin-embedded tissues. (1985)

Monoclonal antibody to Leu-M1, a granulocyte-related differentiation antigen, represents a highly effective reagent for detection of diagnostic Reed-Sternberg (R-S) cells and variants in paraffin-embedded tissues of Hodgkin's disease. In 69 of 73 cases of Hodgkin's disease (41 nodular sclerosis, 25 mixed cellularity, 4 lymphocyte predominance, and 3 lymphocyte depletion types), R-S cells were strongly immunoreactive for Leu-M1. Four cases of lymphocyte predominance Hodgkin's disease (nodular) were uniformly nonreactive for Leu-M1. In most of the positive cases (57/69, 83%), the majority (60-90%) of R-S cells and variants exhibited immunoreactivity for Leu-M1. A characteristic staining pattern included granular and/or vesicular cytoplasmic immunoreactivity, often with a prominent globular paranuclear reaction product, and membrane staining with highly irregular cytoplasmic borders. Evaluation of B-cell (37 specimens), T-cell (20 specimens), and true histiocytic (3 specimens) neoplasms and a case of mastocytosis revealed immunoreactivity for Leu-M1 only in 1 B-cell and 4 T-cell malignancies. The staining patterns in these cases, however, clearly differed from that observed for R-S cells. Studies of nonneoplastic lymphoid tissues (38 total) demonstrated that lymphoid cells were typically nonreactive; histiocytes revealed variable reactivity for Leu-M1. Occasional histiocytes of the sinusoidal network of lymph nodes, particularly in toxoplasmic lymphadenitis, exhibited a staining pattern (membranous/cytoplasmic/paranuclear) similar to that observed for R-S cells. Leu-M1 represents a potentially helpful diagnostic discriminant in the assessment of Hodgkin's disease and its distinction from non-Hodgkin's lymphomas and other lymphoid proliferations.
Minireview (1997)

The title compound Ta6Br12(2+) is of interest for the analysis of biological structures as a heavy metal derivative with great potential for the structure determination of large protein systems. In macromolecular crystallography the phases of the measured structure factor amplitudes have to be determined by compounds that produce measurable changes of the diffraction intensities. Ta6Br12(2+) uniquely meets the demands of a heavy metal derivative and is an important tool for phase determination, especially considering the structure determination of large protein systems.
Evaluation of RU-Netra ¿ Tactile Feedback Navigation System For The Visually Impaired (2006)

An evaluation of novel tactile navigation system for the blind is described in this paper. The handle processes ultrasonic sensor signals and conveys information to the user through variable and synchronized vibrations, which will enhance the sense of orientation and distance for the user. Various tactile perception patterns are used to convey information to the user using sensitivity of the hand. These schemes give feedback to the user using various vibrating patterns which are dependent on three parameters namely intensity of vibration, location of the vibro-tactile actuator and the pulse duration of sensing signal. We are showing different navigation scenario results of the device on 15 sighted users of different age group, genders and hand sizes by making them blindfolded. The prototype has an ergonomic design, is lightweight, compact, and adjustable to different hand sizes
Highly integrated flexible electronic Circuits and Modules (2008)

Within the electronic circuit board industry flexible circuit still cover a small the market share, however, with the fastest growth rate. The technology is increasingly used in automotives and aerospace, in handheld mobile appliances and many medical devices like pace makers or hearing aids [1,2]. Over past years a European consortium of research institutes and industry has explored the future technological potential of flexible printed circuits in the framework of the project SHIFT. One aspect was to investigate the frontiers of flexible circuit fabrication with respect to minimum feasible line width and pitch using different manufacturing methods. Still further beyond today mainstream flex fabrication technologies were the developments to integrate active and passive components into the buildup layers of flex circuits. In this way extremely high integration of electronic systems and highest functional densities can potentially be realized. Techniques and results of these developments will be presented in this paper. Embedded components in order to comply with the thin buildups of flexible circuits should be very thin as well. To this aim components were be mechanically thinned to 20 ptm. A dicing by grinding technique was applied using etched separation grooves on the wafer. Two technologies for embedding of ultra thin components were developed. The first one is thin flip chip assembly on inner layers of the flex and embedding by subsequent lamination of build up layers. The gap between chip and substrate was in the order of a few microns using either low profile solder or anisotropic adhesive.

In vivo droplet vaporization for occlusion therapy and phase aberration correction (2002)

The objective was to determine whether a transpulmonary droplet emulsion (90%, <6 microm diameter) could be used to form large gas bubbles (>30 microm) temporarily in vivo. Such bubbles could occlude a targeted capillary bed when used in a large number density. Alternatively, for a very sparse population of droplets, the resulting gas bubbles could serve as point beacons for phase aberration corrections in ultrasonic imaging. Gas bubbles can be made in vivo by acoustic droplet vaporization (ADV) of injected, superheated, dodecafluoropentane droplets. Droplets vaporize in an acoustic field whose peak rarefactional pressure exceeds a well-defined threshold. In this new work, it has been found that intraarterial and intravenous injections can be used to introduce the emulsion into the blood stream for subsequent ADV (B- and M-mode on a clinical scanner) in situ. Intravenous administration results in a lower gas bubble yield, possibly because of filtering in the lung, dilution in the blood volume, or other circulatory effects. Results show that for occlusion purposes, a reduction in regional blood flow of 34% can be achieved. Individual point beacons with a +24 dB backscatter amplitude relative to white matter were created by intravenous injection and ADV.
