Motion correction in periodically‐rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) and turboprop MRI (2009)

Periodically-rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) and Turboprop MRI are characterized by greatly reduced sensitivity to motion, compared to their predecessors, fast spin-echo (FSE) and gradient and spin-echo (GRASE), respectively. This is due to the inherent self-navigation and motion correction of PROPELLER-based techniques. However, it is unknown how various acquisition parameters that determine k-space sampling affect the accuracy of motion correction in PROPELLER and Turboprop MRI. The goal of this work was to evaluate the accuracy of motion correction in both techniques, to identify an optimal rotation correction approach, and determine acquisition strategies for optimal motion correction. It was demonstrated that blades with multiple lines allow more accurate estimation of motion than blades with fewer lines. Also, it was shown that Turboprop MRI is less sensitive to motion than PROPELLER. Furthermore, it was demonstrated that the number of blades does not significantly affect motion correction. Finally, clinically appropriate acquisition strategies that optimize motion correction are discussed for PROPELLER and Turboprop MRI.
Comparison of Actiwatch?? activity monitor and Children???s Activity Rating Scale in children (2000)

Our results indicate that the 3-min CARS score correlates with 3-min activity counts, favoring the use of the activity monitors in assessing physical activity in preschool-aged children.
Studies on Sulfonylurea Derivatives. II (1959)

In order to examine the hypoglycemic action of the compounds of sulfonylurea series previously synthesized, variation of blood sugar level was examined using albino rats, with oral administration of D-860 as a standard and of water as the control. The difference of the group treated with D-860 from the control was proved highly significant after comparison of mean values of blood sugar and the further stochastical analysis. In the light of these data, it was found reasonable to examine the hypoglycemic activity of each sample by this method.
Seized by the Nymph? (2012)

Alors que les pratiques dédicatoires ont été régulièrement étudiées par les historiens de la religion grecque, un important dossier chypriote a jusqu’ici été quasiment négligé. Il s’agit d’un sanctuaire rupestre situé sur la colline de Kafizin, où quelque 310 fragments de céramique inscrits ont été mis au jour, dont la grande majorité porte le nom d’Onesagoras, fils de Philounios, et est dédiée à une Nymphe, entre 225 et 218 avant notre ère. Onesagoras a manifesté une telle intensité dans le culte de la Nymphe qu’il peut être considéré comme un nympholepte ou « possédé par une Nymphe ». Le dossier comprend un matériel important pour l’étude des pratiques religieuses à un niveau intermédiaire dans la polis. Cet article entend porter ce matériel à l’attention de ceux qui étudient la religion grecque, en soulevant les questions qu’il pose en matière de pratiques dédicatoires.
Changes in the expression of potassium channels during mouse T cell development. (1986)

In this report we have combined the whole-cell electrophysiological recording technique with flow microfluorometry to isolate phenotypically defined thymocytes and T lymphocytes. Results obtained showed that J11d-/Lyt-2-/L3T4- cells express none or very few delayed rectifier K+ channels, whereas most other Lyt-2-/L3T4- cells, as well as typical cortical thymocytes (Lyt-2+/L3T4+), do express K+ channels. Mature (Lyt-2+/L3T4- or Lyt-2-/L3T4+) thymocytes, which are heterogeneous for J11d expression, were also found to be heterogeneous for K+ channel expression. Consistent with this finding was the observation that the cortisone-resistant subpopulation of thymocytes, which express low levels of J11d, were enriched for cells expressing low levels of K+ channels. Mature phenotype peripheral T lymphocytes expressed very low levels of K+ channels, but upon activation with Con A were found to express high levels of K+ channels. The results suggest that K+ channel expression in T cells is developmentally regulated. Increased expression of the channel is induced in response to mitogenic signals throughout the T cell lineage. Expression of the channel, therefore, serves as a useful marker in defining steps in the T cell differentiation pathway.
Characterization of Silver Inkjet Overlap-printing through Cohesion and Adhesion (2012)

We introduce an understanding of silver (Ag) inkjet overlap-printing characteristics from the viewpoints of cohesion between ink droplets and adhesion between an ink droplet and a surface. The printing characteristics were closely monitored by changing the surface energy to elucidate the effect of adhesion and cohesion on printing instability, such as droplet merging and line bulging. The surface energy of the substrate was changed through the hydrophilization of a hydrophobic fluorocarbon-coated surface. The surface energy and ink wettability of the prepared surfaces were characterized using sessile drop contact angle analysis, and printing instability was observed using an optical microscope after drop-on-demand inkjet printing with a 50% overlap in diameter of deposited singlet patterns. We found that the surface energy is not an appropriate indicator based on the experimental results of Ag ink printing on a hydrofluoric-treated silicon surface. The analytical approach using adhesion and cohesion was helpful in understanding the instability of the inkjet overlap-printing, as adhesion and cohesion represent the direct interfacial relationship between the Ag inks used and the substrate.
Complex Formation of Cation-Exchanged Montmorillonites with Propylene Carbonate: Osmotic Swelling in Aqueous Electrolyte Solutions (1999)

Abstract Montmorillonites saturated with Li + , Na + , K + , NH 4 + , Mg 2+ , Ca 2+ , Ba 2+ , or Ni 2+ ions can form complexes with propylene carbonate (PC) by intercalation; the d (001) of montmorillonite expands to 19 Å. In the infrared absorption spectra of these complexes, the C=0 stretching band of the intercalated PC molecules shifts to lower frequencies, and the amount of the shift increased with the increase of the polarizing power of the interlayer cations. Water molecules were strongly bound to the cations. The PC molecules interacted with the cations by way of H 2 O molecules. With the removal of H 2 O, the PC molecules directly coordinate to the cations and the PC molecules show a much larger red-shift in the C=O frequency. The PC-montmorillonite complexes exhibited osmotic swelling, even in aqueous electrolyte solutions. This finding is interpreted in terms of the formation of thick electric double-layers consisting of PC and H 2 O between the 2:1 layers.
Cloning, Expression in Escherichia coli and Nucleotide Sequence of a Tetracycline-resistance Gene from Streptomyces rimosus (1988)

Determinants of tetracycline resistance have been cloned from two different tetracycline-producing industrial strains of Streptomyces into Streptomyces lividans using the plasmid vector pUT206. Three plasmids, pUT250 and pUT260 with a 9.5 and a 7.5 kb insert respectively of Streptomyces rimosus DNA, and pUT270 with a 14.0 kb insert of Streptomyces aureofaciens DNA, conferring resistance to tetracycline, have been isolated. By in vitro sub-cloning, a similar fragment of 2.45 kb containing the tetracycline resistance gene (tet347) was further localized on these plasmids. The S. rimosus gene has been cloned into Escherichia coli and expressed under the control of lambda pL or Lpp promoters. Differential protein extraction of E. coli cells revealed the presence of an additional membrane-embedded protein in tetracycline-resistant cells. On the basis of available restriction endonuclease maps, the tet347 gene is probably identical to the tetB gene from S. rimosus recently identified by T. Ohnuki and co-workers as responsible for the reduced accumulation of tetracycline. The nucleotide sequence of a 2052 bp DNA fragment containing the TcR structural gene from S. rimosus has been determined. The amino acid sequence of the tet347 protein (Mr35818) deduced from the nucleotide sequence shows a limited but significant homology to other characterized tetracycline transport acting determinants from pathogenic bacteria.
Effects of search success on search engine re-use (2011)

People's experiences when interacting with online services affects their decisions on reuse. Users of Web search engines are primarily focused on obtaining relevant information pertaining to their query. Search engines that fail to satisfy users' information needs may find their market share to be negatively affected. However, despite its importance to search providers, the relationship be-tween search success and search engine reuse is poorly understood. In this paper, we present a longitudinal log-based study with a large cohort of search engine users that quantifies the relationship between success and re-use of search engines. We use time series analysis to define two groups of users: stationary and non-stationary. We find that recent changes in satisfaction rate do correlate moderately with changes in rate of return for stationary users. For non-stationary users, we find that satisfaction and rate of return change together and in the same direction. We also find that some effects are stronger for a smaller player on the market than for a clear market leader, but both are affected. This is the first study to explore these issues in the context of Web search, and our findings have implications for search providers seeking to better understand their users and improving their experience.
Arrival Time Estimation (ETA) from On-Final to Gate (2007)

[Abstract] Accurate prediction of taxi-times on the airport surface is a key component of the collaborative decision making (CDM) concept of operations for efficient management of airport resources. The benefits of improved accuracy in predicted taxi-times are better gate management and reduced arrival and departure delays. This research supports the development of a predictive tool for the estimation of the arrival time at the gate for an aircraft when it is on its final approach, including estimation of threshold crossing time and on-ground taxi-time. Initial model development for Detroit Wayne County International (DTW) Airport predicts taxi-time from taxi-paths and conditioning factors identified from analysis of surface surveillance data. This work demonstrates the feasibility of automatic identification of taxi-paths from surveillance data, with application to taxi-route conformance monitoring. Development of a rule set for selection of arrival taxipaths (wheels-down to ramp area) shows that it is possible to predict taxi-time with a standard error of 1.67 minutes, based on eight dates of data in May 2006. Conditioning factors used to develop the rule set include arrival runway, ramp destination, aircraft type, and taxi-path.

Establishing Trust in Hybrid Cloud Computing Environments (2011)

Establishing trust for resource sharing and collaboration has become an important issue in distributed computing environment. In this paper, we investigate the problem of establishing trust in hybrid cloud computing environments. As the scope of federated cloud computing enlarges to ubiquitous and pervasive computing, there will be a need to assess and maintain the trustworthiness of the cloud computing entities. We present a fully distributed framework that enable trust-based cloud customer and cloud service provider interactions. The framework aids a service consumer in assigning an appropriate weight to the feedback of different raters regarding a prospective service provider. Based on the framework, we developed a mechanism for controlling falsified feedback ratings from iteratively exerting trust level contamination due to falsified feedback ratings. The experimental analysis shows that the proposed framework successfully dilutes the effects of falsified feedback ratings, thereby facilitating accurate and fair assessment of the service reputations.
The Arabidopsis <i>SLEEPY1</i> Gene Encodes a Putative F-Box Subunit of an SCF E3 Ubiquitin Ligase[W] (2003)

Abstract The Arabidopsis SLY1 (SLEEPY1) gene positively regulates gibberellin (GA) signaling. Positional cloning of SLY1 revealed that it encodes a putative F-box protein. This result suggests that SLY1 is the F-box subunit of an SCF E3 ubiquitin ligase that regulates GA responses. The DELLA domain protein RGA (repressor of ga1-3) is a repressor of GA response that appears to undergo GA-stimulated protein degradation. RGA is a potential substrate of SLY1, because sly1 mutations cause a significant increase in RGA protein accumulation even after GA treatment. This result suggests SCFSLY1-targeted degradation of RGA through the 26S proteasome pathway. Further support for this model is provided by the observation that an rga null allele partially suppresses the sly1-10 mutant phenotype. The predicted SLY1 amino acid sequence is highly conserved among plants, indicating a key role in GA response.
A Sub-100mV Ultra-Low Voltage Level-Shifter Using Current Limiting Cross-Coupled Technique for Wide-Range Conversion to I/O Voltage (2020)

In this paper, a sub-100mV ultra-low-voltage level-shifter for wide-range voltage conversion to I/O voltage is presented. The level-shifter uses a current limiting diode-connected transistor with crosscoupled transistor structure to reduce the minimum input voltage down to 100mV while covering a wide output voltage range up to I/O supply voltage (3V). We propose an improved split-control output buffer to reduce the static current from VDDH to VSS. The level-shifter is implemented using X-FAB 180nm HV CMOS process. The post-layout simulations show that the proposed structure achieves an average propagation delay of 7.57μ s with a power consumption of 3.43nW when the supply voltages VDDL, VDDH, and input frequency are 100mV, 3V, and 1kHz, respectively. The design occupies 182.46μ m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> silicon area with a static power consumption of 3nW when VDDL and VDDH are 100mV and 3V, respectively, which is suitable for low power applications.
Multistep Continuous-Flow Synthesis of (–)-Oseltamivir (2016)

A continuous-flow synthesis of (–)-oseltamivir composed of five flow units was accomplished. In each unit, the following reactions proceed efficiently: (1) a diphenylprolinol silyl ether mediated Michael reaction, (2) a domino reaction of Michael and intermolecular Horner–Wadsworth–Emmons reactions, (3) protonation, (4) epimerization, and (5) reduction of a nitro group to an amine. (–)-Oseltamivir was obtained in 13% total yield through a single flow with a residence time of 310 minutes.
Chemistry of arsenic removal during coagulation and Fe–Mn oxidation (1994)

Recent studies have indicated that arsenic in drinking water is as hazardous as radon in homes and secondhand tobacco smoke. Arsenic removal during coagulation or Fe–Mn oxidation is examined to aid utilities that desire to improve arsenic removal. Fundamental mechanisms of arsenic removal are discussed, optimization strategies are forwarded, and some new insights are provided to guide future research. Specifically, As(III) removals by coagulation are primarily controlled by coagulant dose and relatively unaffected by solution pH, whereas the converse is true for As(V). When compared on the basis of moles iron or aluminum hydroxide solid formed during coagulation, iron and aluminum coagulants are of demonstrably equal effectiveness in removing As(V) at pH <7.5. However, iron‐based coagulants are advantageous if soluble metal residuals are problematic, if pH is >7.5, or if the raw water contains As(III). Arsenic removal during Fe–Mn oxidation is controlled by the quantity of iron removed [Fe(OH) 3 formed] and is relatively independent of the quantity of manganese removed (MnOOH formed).
An implementation of flush channels based on a verification methodology (2003)

Flush channels generalize more conventional asynchronous message passing protocols. A distributed system that uses flush channels allows a programmer the flexibility of specifying the delivery order of each message in relation to other messages transmitted on the channel. An implementation technique that follows directly from a verification methodology for flush channels is presented. A relatively formal argument in support of the technique is included.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Bending Behavior of Composite Girders with Cold Formed Steel U Section (2002)

A new type of steel and concrete composite bridge with steel U-shape girders has been proposed. The U girder can be cold formed from one steel sheet, and the amount of welding required is substantially small and mass production could be possible. This new bridge would be therefore very economical. The steel U girder is composite with the reinforced concrete slab at the span center, whereas concrete is poured into the steel U section and prestressed at the intermediate supports of a continuous bridge. Bending tests were carried out to investigate the static bending behavior of the girder models. The girder model at the span center behaved as a composite beam. The girder model at the intermediate supports behaved as a prestressed beam and the filled concrete restricted the local buckling of steel plates in compression. A design calculation method for the girder section has been proposed assuming the Bernoulli-Euler principle, and was verified by the test results. This study shows that the new composite girder has sufficient bending strength and deformation capacity, and this bridge system is practical and feasible.
A New Hypothesis of the Etiology of Amyotrophic Lateral Sclerosis (1982)

Evidence is accumulating that a number of previously unexplained human diseases amy arise from a deficiency of DNA repair enzymes. Studies on the motoneurons of patients with amyotrophic lateral sclerosis (ALS), and those of an animal model of motoneuronal degeneration, the wobbler mouse, indicate the presence of major abnormalities of RNA metabolism. We advance the hypothesis that the primary abnormality in ALS is the accumulation of abnormal DNA, which is unable to undertake normal transcription, in motoneurons. This abnormal DNA may arise from a deficiency of an isozyme of one of the DNA repair enzymes.
Excitation of Mode Groups in Multimode Fibers With the Aid of Diffractive Optics (2016)

In this letter, we report on the excitation of low order Laguerre-Gaussian mode groups with a common propagation constant in a multimode gradient index optical fiber. Enabling generic space-division multiplexer was based on a key multichannel diffractive optical element. The experimental results show integrity of the excited mode groups in an OM2 multimode fiber optic patch cord.
Foundations of Business Process Modeling (2009)

This chapter provides an overview of business process management and business process modeling. We approach business process management by giving a historical classification of seminal work, and define it by the help of the business process management life cycle. Business process models play an important role in this life cycle, in particular, if information systems are used for executing processes. We deduct a definition for business process modeling based on a discussion of modeling from a general information systems point of view. In the following, we detail business process modeling techniques, in particular, modeling languages and modeling procedures for business process modeling. Finally, we discuss some future trends with a focus on the business process execution language for Web services (BPEL), and conclude the chapter with a summary. The chapter aims to cover business process modeling in a comprehensive way such that academics and practitioners can use it as a reference for identifying more specialized works.
RNA-dependent RNA polymerase consensus sequence of the L-A double-stranded RNA virus: definition of essential domains. (1992)

The L-A double-stranded RNA virus of Saccharomyces cerevisiae makes a gag-pol fusion protein by a -1 ribosomal frameshift. The pol amino acid sequence includes consensus patterns typical of the RNA-dependent RNA polymerases (EC 2.7.7.48) of (+) strand and double-stranded RNA viruses of animals and plants. We have carried out "alanine-scanning mutagenesis" of the region of L-A including the two most conserved polymerase motifs, SG...T...NT..N (. = any amino acid) and GDD. By constructing and analyzing 46 different mutations in and around the RNA polymerase consensus regions, we have precisely defined the extent of domains and specific residues essential for viral replication. Assuming that this highly conserved region has a common secondary structure among different viruses, we predict a largely beta-sheet structure.
Optical properties of a liquid crystal microlens (1990)

The liquid crystal microlens can be obtained by molecular orientation effects in a non-uniform electric field which is produced by the asymmetric electrode structure with a hole-patterned electrode and an ITO coated counter electrode. In this cell, an axially symmetric distribution of the liquid crystal molecules; that is, a radial distribution of refractive indices is achieved. Relations between the optical properties and the geometric factors, such as the diameter of the hole-pattern and the thickness of the cell are investigated. An optical fiber coupler with a variable coupling efficiency is prepared and its switching properties are discussed.
Improved Electromagnetic Interference Shielding Properties Through the Use of Segregate Carbon Nanotube Networks (2019)

We report the enhanced electromagnetic interference (EMI) shielding properties of hybrid carbon nanotube (CNT) composites consisting of more than two kinds of fillers through the use of segregate conducting networks. An excluded volume was created by micro-sized silica particles that concentrate the CNT network, resulting in improved electrical conductivity and microwave properties. To achieve the optimal dispersion of CNTs and silica particles, high shear force was applied to the pre-cured composite mixture via three-roll milling. Depending on the micro-silica content ratio, we observed improved electrical conductivity and EMI shielding properties. For a quantitative comparison to observe the excluded-volume effects, a CNT composite without micro-silica was measured in parallel with the other sample.
X-Ray and Dielectric Studies of the Systems (Ba<sub>1-<i>x</i></sub>R<sub>2<i>x</i>/3</sub>)Nb<sub>2</sub>O<sub>6</sub>, Where R is Y, Sm or La (1964)

New ferroelectric tungsten bronze type solid solutions were found with compositions 0.2≤ x ≤0.4 for Sm and La compounds, and x =0.25 for Y compound. The maximum dielectric constants were observed at about x =0.2 for each system, and corresponding Curie points were 278°C, 189°C and 10°C for Y, Sm and La compounds respectively. The hysteresis loops were observed below the respective transition temperatures. In R 2 O 3 -BaO-Nb 2 O 5 system, single phase region of tungsten bronze type structure is determined. End member of the system, RNb 3 O 9 for Sm, or Y system, was mixture of RNbO 4 and Nb 2 O 5 , but for La system a new compound LaNb 3 O 9 was identified.
