Microfluidic-Based Robotic Sampling System for Radioactive Solutions (2014)

A novel microfluidic-based robotic sampling system has been developed for sampling and analysis of liquid solutions in nuclear processes. This system couples the use of a microfluidic sample chip with a robotic system designed to allow remote, automated sampling of process solutions in-cell and facilitates direct coupling of the microfluidic sample chip with analytical instrumentation. This system provides the capability for near-real-time analysis, reduces analytical waste, and minimizes the potential for personnel exposure associated with traditional sampling methods. A prototype sampling system was designed, built, and tested. System testing demonstrated operability of the microfluidic-based sample system and identified system modifications to optimize performance.
Centrifugal Shape Sorting and Optical Response of Polyhedral Gold Nanoparticles (2013)

A centrifugal route for separating small {110}-faceted gold nanostructures, namely rhombic dodecahedra (RD) and triangular bipyramids (BPs), which form simultaneously during synthesis and cannot be separated by means of conventional filtration methods, is presented. The centrifuged solution shows two distinct bands: i) RD and ii) BPs, as verified in the corresponding scanning electron microscopy images. The sorted BPs show a refractive index dependence 2.5 times that of the as-synthesized, unsorted mixture.
Search for supersymmetry in electroweak production with photons and large missing transverse energy in pp collisions at s=8TeV (2016)

Results are reported from a search for supersymmetry with gauge-mediated supersymmetry breaking in electroweak production. Final states with photons and large missing transverse energy (E miss T ) were examined. The data sample was collected in pp collisions at s = 8 TeV with the CMS detector at the LHC and corresponds to 7.4 fb -1 . The analysis focuses on scenarios in which the lightest neutralino has bino-or wino-like components, resulting in decays to photons and gravitinos, where the gravitinos escape undetected. The data were obtained using a specially designed trigger with dedicated low thresholds, providing good sensitivity to signatures with photons, E miss T , and low hadronic energy. No excess of events over the standard model expectation is observed. The results are interpreted using the model of general gauge mediation. With the wino mass fixed at 10 GeV above that of the bino, wino masses below 710 GeV are excluded at 95% confidence level. Constraints are also set in the context of two simplified models, for which the analysis sets the lowest cross section limits on the electroweak production of supersymmetric particles.

Protein Chain Initiation by Methionyl Transfer Ribonucleic Acid in the Cytoplasm of Neurospora (1971)

Abstract The initiation of protein biosynthesis in the cytoplasmic system of Neurospora crassa has been investigated. Two major methionyl-tRNA species exist in the cytoplasm of Neurospora, only one of which (methionyl-tRNAf) is formylatable with Escherichia coli transformylase. In addition, methionyl-tRNAf has more affinity to bind on ribosomes in the presence of the AUG codon than methionyl-tRNAm. This methionyl-tRNAf appears to function for the initiation of protein biosynthesis by incorporating methionine at the amino-terminal end of proteins. In contrast, methionyl-tRNAm transfers methionine predominantly into the internal positions. This investigation provides evidence that protein biosynthesis in the cytoplasm of Neurospora is initiated by methionyl-tRNAf without prior formylation.
EPR data on the self-interstitial complex O3 in diamond (2000)

A previously unreported defect, which is labeled $O3,$ has been observed in the EPR spectrum of synthetic type-IIa diamonds irradiated at 100 K with 2 MeV electrons. This defect was not observed in identical diamonds whose temperature during electron irradiation was \ensuremath{\geqslant}300 K. This center has also been observed in neutron irradiated natural type-Ib diamonds, but only after isochronal annealing at about 650 K: it subsequently annealed out at about 720 K. Analysis of the angular variation of the EPR line positions has determined the zero-field interaction $(\underset{\ifmmode\bar\else\textasciimacron\fi{}}{\mathbf{D}}),$ showing that the center has a triplet $S=1$ ground state and ${C}_{2}$ symmetry, with a $〈100〉$ rotation axis. The use of a synthetic type-IIa diamond with 5% ${}^{13}\mathrm{C}$ isotopic enrichment allowed observation of ${}^{13}\mathrm{C}$ hyperfine satellites. Analysis of the ${}^{13}\mathrm{C}$ hyperfine couplings by a simple molecular orbital calculation shows that 76% of the unpaired electronic wave function is localized in two nonbonding $2p$ orbitals, on different carbon atoms. Interpretation of the parameter $\underset{\ifmmode\bar\else\textasciimacron\fi{}}{\mathbf{D}}$ as arising primarily from dipole-dipole interaction between these two orbitals indicates that they are separated by 0.32(2) nm. The nonbonding $2p$ orbitals indicate the involvement of $〈100〉$-split interstitials $({\mathbf{I}}_{100})$ in the structure. Two possible models are proposed, one involving two and one three parallel ${\mathbf{I}}_{100}$ at next-nearest-neighbor positions, of which the latter gives the better fit to the data.
A Reconfigurable Reflective/Absorptive SPDT Plasma Switch (2023)

For the first time in solid-state plasma technology, an SPST and SPDT switch is presented that can reconfigure its input impedance to match any real impedance, creating a dual-mode reflective/absorptive operation. Up to 6 GHz, the SPST switch's measured insertion loss is 0.27 dB, absorptive OFF-state return loss greater than 17.5 dB, and isolation (both modes) greater than 22.5 dB. The SPDT switch exhibits measured insertion loss less than 0.43 dB, absorptive OFF-state return loss greater than 16.8 dB, and RF-RF and Com-RF isolation greater than 28 dB and 25 dB (both modes), respectively, up to 4 GHz. The 50-Ω absorptive state consumes 46× less optical power than its reflective state and demonstrates greater than 10 dB return loss up to 33 dBm, and no failure up to 40 dBm. This work shows state-of-the-art low loss and absorbed power handling results in a novel, reconfigurable topology.
Extremely Tight Binding of a Ruthenium Complex to Glycogen Synthase Kinase 3 (2008)

Perfect match: An organoruthenium complex with at most a low picomolar binding constant for glycogen synthase kinases 3 is reported, whose binding to the ATP-binding site has been analyzed by X-ray crystallography. The complex, (RRu)-NP549, is one of the most potent protein kinase inhibitors reported to date, almost four orders of magnitude more potent than the related natural product staurosporine.
Privacy Preservation for Participatory Sensing Applications (2016)

Participatory sensing, which collects environmental information from mobile phone users, is growing in popularity. The collected information can be used for national policy or decision-making for companies. However, sensing users may violate their privacy. Recent studies have proposed negative surveys which can analyze the attributes of users statistically without precise information about each user's information. The traditional negative surveys need a lot of samples for proper estimation. These days, several types of negative surveys are used that can estimate the distribution of user attributes with a high degree of accuracy. However, privacy levels of these methods are relatively low. Moreover, existing studies assume that the privacy levels of all users are the same. In this paper, we propose a new negative survey that can estimate data distributions with more precision and can be used in a situation where the privacy levels are different based on each user's demand. By simulations of a synthetic and a real data set, we prove that our proposed method can estimate more precisely than existing methods.
Deconstructing Categorization in Visualization Recommendation: A\n Taxonomy and Comparative Study (2021)

Visualization recommendation (VisRec) systems provide users with suggestions\nfor potentially interesting and useful next steps during exploratory data\nanalysis. These recommendations are typically organized into categories based\non their analytical actions, i.e., operations employed to transition from the\ncurrent exploration state to a recommended visualization. However, despite the\nemergence of a plethora of VisRec systems in recent work, the utility of the\ncategories employed by these systems in analytical workflows has not been\nsystematically investigated. Our paper explores the efficacy of recommendation\ncategories by formalizing a taxonomy of common categories and developing a\nsystem, Frontier, that implements these categories. Using Frontier, we evaluate\nworkflow strategies adopted by users and how categories influence those\nstrategies. Participants found recommendations that add attributes to enhance\nthe current visualization and recommendations that filter to sub-populations to\nbe comparatively most useful during data exploration. Our findings pave the way\nfor next-generation VisRec systems that are adaptive and personalized via\ncarefully chosen, effective recommendation categories.\n

Low energy ion scattering (LEIS). A practical introduction to its theory, instrumentation, and applications (2016)

Low energy ion scattering (LEIS) probes the elemental composition of the outermost atomic layer of a material and provides static depth profiles of the outer ca. 10 nm of surfaces. Its extreme surface sensitivity and quantitative nature make it a powerful tool for studying the relationships between surface chemistry and surface related phenomena such as wetting, adhesion, contamination, and thin film growth. The high depth resolution obtained in LEIS in its static and sputter depth profile modes are useful for studying the layer structures of thin films. LEIS instrumentation has improved significantly in recent years, showing dramatic increases in its sensitivity and further expanding its potential applications. In this article, we provide a practical introduction to the technique, including a discussion of the basic theory of LEIS, LEIS spectra, LEIS instrumentation, and LEIS applications, including catalysts, solid oxide fuel cells (SOFCs), and thin films in integrated circuits.
Noise reduction of severely corrupted image sequences (1993)

A nonlinear adaptive noise filter for filtering the nonstationary signals from image sequences is presented. The filter uses estimates of the local statistics to adapt instantaneously. The authors propose to use a robust recursive estimator for those statistics which is based on order statistics. Prior to filtering, motion is estimated from the sequence and compensated for. For the estimation, a recursive block-matcher is used with a match criterion based on higher order statistics. By weighing out outlier data, this estimator provides robust estimates. The overall combination is able adequately to remove severe noise while maintaining sharp results. The computational complexity makes the method suitable for off-line processing only.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Genetic Analysis of Capsular Polysaccharide Synthesis Gene Clusters from All Serotypes of Streptococcus suis: Potential Mechanisms for Generation of Capsular Variation (2013)

Streptococcus suis strains are classified into 35 serotypes on the basis of the antigenicity of their capsular polysaccharides (CPs). CP synthesis genes are known to be clustered on the chromosome (cps gene cluster). The entire cps gene clusters of S. suis have so far been sequenced in 15 serotypes and found to be located between orfZ and aroA. In this study, to provide comprehensive information about S. suis CPs, we sequenced the entire cps gene clusters of the remaining serotypes and analyzed the complete set of S. suis cps gene clusters. Among the 35 cps gene clusters, 22 were located between orfZ and aroA, whereas the other 13 were flanked by other gene(s) on the chromosomes, and the chromosomal locus was classified into five patterns. By clustering analysis, the predicted products of cps genes found in the 35 serotypes were assigned into 291 homology groups, and all serotypes possessed a serotype-specific gene, except for serotypes 1, 2, 1/2, and 14. Because of the presence of genes encoding flippase (wzx) and polymerase (wzy), CPs of all serotypes were thought to be synthesized by the Wzx/Wzy pathway. Our data also implied the possibility of the transfer of the entire or partial cps gene clusters among S. suis strains, as well as the influence of spontaneous mutations in a single gene or a few genes on the antigenicity of some serotypes. Accumulation of these gene transfers and small-scale mutations may have generated the antigenic diversity of S. suis CPs.
Variation in Hospital Risk–Adjusted Mortality Rates Following Transcatheter Aortic Valve Replacement in the United States (2016)

Background— The use of transcatheter aortic valve replacement (TAVR) to treat aortic stenosis in the United States is growing, yet little is known about the variation in procedural outcomes in community practice. We developed a TAVR in-hospital mortality risk model and used it to quantify variation in mortality rates across United States (US) TAVR centers. Methods and Results— We analyzed data from 22 248 TAVR procedures performed at 318 sites participating in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry (November 2011 to October 2014). A Bayesian hierarchical model was developed to estimate hospital-specific risk-adjusted mortality rates adjusting for 40 patient baseline factors. A total of 1130 in-hospital deaths (5.1%) were observed. Reliability-adjusted risk-adjusted mortality rate estimates ranged from 3.4% to 7.7% with an interquartile range of 4.8% to 5.4%. A patient’s predicted odds of dying was 80% higher if treated by a hospital 1 standard deviation above the mean compared with a hospital 1 standard deviation below the mean (odds ratio =1.8; 95% credible interval, 1.4%–2.2%). Conclusions— Risk modeling of TAVR in-hospital mortality revealed variation in risk-adjusted mortality rates during the US early commercial experience. Transcatheter Valve Therapy Registry analyses using this model will support research, feedback reporting, and the identification of factors associated with quality.

Androgen influence on the meibomian gland. (2000)

The findings show that the meibomian gland is an androgen target organ and that androgens influence the lipid profile within this tissue. However, the extent to which androgens regulate the production of these lipids and whether this action may impact tear film stability remain to be determined.
Discovery and Optimization of Novel Pyridines as Highly Potent and Selective Glycogen Synthase Kinase 3 Inhibitors (2019)

&lt;div&gt;Glycogen synthase kinase-3 plays an essential role in multiple biochemical pathways in the cell, particularly in regards to energy regulation. As such, Glycogen synthase kinase-3 is an attractive target for pharmacological intervention in a variety of disease states, particularly non-insulin dependent diabetes mellitus. However, due to homology with other crucial kinases, such as the cyclin-dependent protein kinase CDC2, developing compounds that are both potent and selective is challenging. A novel series of derivatives of 5-nitro-N2-(2-(pyridine-2ylamino)ethyl)pyridine-2,6-diamine were synthesized and have been shown to potently inhibit glycogen synthase kinase-3 (GSK3). Potency in the low nanomolar range was obtained along with remarkable selectivity. The compounds activate glycogen synthase in insulin receptor-expressing CHO-IR cells and in primary rat hepatocytes, and have acceptable pharmacokinetics and pharmacodynamics to allow for oral dosing. The X-ray co-crystal structure of human GSK3-beta in complex with compound 2 is reported and provides insights into the structural determinants of the series responsible for its potency and selectivity.&lt;/div&gt;&lt;div&gt;&lt;br&gt;&lt;/div&gt;

Randomized byzantine generals (1983)

We present a randomized solution for the Byzantine Generals Problems. The solution works in the synchronous as well as the asynchronous case and produces Byzantine Agreement within a fixed small expected number of computational rounds, independent of the number n of processes and the bound t on the number of faulty processes. The solution uses A. Shamir's method for sharing secrets. It specializes to produce a simple solution for the Distributed Commit problem.
Cachexia-Like Symptoms Predict a Worse Prognosis in Localized T1 Renal Cell Carcinoma. (2004)

Cachexia-like symptoms independently predict a worse prognosis in patients with T1 RCC. Patients with cachexia (malaise, weight loss, anorexia and hypoalbuminemia), especially when associated with high grade tumors, should be considered for clinical trials of adjuvant therapies.
A 3D finite element analysis of large‐scale nonlinear dynamic electromagnetic problems by harmonic balancing and domain decomposition (2015)

Abstract The dual–primal finite element tearing and interconnecting (FETI‐DP) method is applied together with the harmonic balance method and the fixed‐point (FP) method to improve the efficiency of three‐dimensional finite element analysis of large‐scale nonlinear dynamic electromagnetic problems. The FETI‐DP method decomposes the original problem into smaller subdomains problems. Combined with parallel computing techniques, the total computation time can be reduced significantly. To account for nonlinear B‐H characteristics, the FP method is applied together with the polarization formulation. Because the FP method assumes a constant reluctivity, it decouples the systems of different harmonics. The FETI‐DP method can then be applied to speed up the simulation of each harmonic in each FP iteration. Two benchmark problems and a three‐phase inductor are simulated by the proposed method to validate the formulation and demonstrate its performance. Copyright © 2015 John Wiley &amp; Sons, Ltd.
Raman Spectroscopic Analysis of Structural Defects in Hot Isostatically Pressed Silicon Nitride. (1999)

Raman spectroscopy was used to analyze the crystal structure of Hot Isostatically Pressed silicon nitride (Si3N4 containing 0.5mol% of Y2O3, 0.5mol% of Nd2O3 and 1mass% of Si3N4 whiskers) to confirm whether microstacking faults occurred in the β-phase due to structural defects in the silicon nitride grains. With this technique, the presence or absence of a 514-520cm-1 peak confirms whether or not such stacking faults have occurred. For the β-phase alone of orientation-controlled silicon nitride, a large grain diameter and high thermal conductivity were obtained. In contrast, for gas-pressure hot-pressed silicon nitride, the grain diameter was smaller and stacking faults occurred in the β-phase, even though the heat treatment process was performed at the same temperature. It was found that structural defects in the crystal grains caused phonon-impurity scattering, resulting in a decline in thermal conductivity. This indicates that structural defects in the grains must be eliminated to obtain high thermal conductivity. The results of this study suggest that Raman spectroscopy can be an effective technique for conducting structural analyses to determine the presence of such defects.
Leader-Based Multicast Service in IEEE 802.11v Networks (2010)

With the advent of various multimedia streaming applications requiring reliability and high bandwidth, multicasting in wireless LANs has been gaining more attentions as the supported bit rate increases. However, according to the specification of the IEEE 802.11 standard, broadcast/multicast frames are transmitted at a fixed and low bit rate due to the absence of a feedback mechanism such as ACK. This simple broadcasting technique with no feedback signal raises some issues; reliability, efficiency and fairness. In this paper, hence, we propose a framework for multicasting termed Leader-Based Multicast Service (LBMS) to alleviate those limitations. LBMS consists of a leader-based transmission and feedback mechanism for multicasting by extending the IEEE 802.11v standard, which is the next-generation standard for network management. Also, we try to support legacy 802.11 stations can still participate in multicasting. Simulation exhibits that the gain of the proposed multicasting scheme increases as (i) more stations compete for the channel, and (ii) the wireless channel condition becomes poorer.
Target following performance in the presence of latency, jitter, and signal dropouts (2011)

In this paper we describe how human target following performance changes in the presence of latency, latency variations, and signal dropouts. Many modern games and game systems allow for networked, remote participation. In such networks latency, variations and dropouts are commonly encountered factors. Our user study reveals that all of the investigated factors decrease tracking performance. The errors increase very quickly for latencies of over 110 ms, for latency jitters above 40 ms, and for dropout rates of more than 10 %. The effects of target velocity on errors are close to linear, and transverse errors are smaller than longitudinal ones. The results can be used to better quantify the effects of different factors on moving objects in interactive scenarios. They also aid the designers in selecting target sizes and velocities, as well as in adjusting smoothing, prediction and compensation algorithms.
Characterizing the Conformationome: Toward a Structural Understanding of the Proteome (2017)

While non-native protein conformations such as folding intermediates are rarely observed in solution such species are often stabilized as gaseous ions during electrospray ionization for mass spectrometry. This opens the possibility of large scale efforts to capture information about many non-native structures such as folding intermediates or malformed conformations having deleterious effects: studies of the conformationome.
The Early and Delayed Analgesic Effects of Ketamine After Total Hip Arthroplasty: A Prospective, Randomized, Controlled, Double-Blind Study (2009)

Ketamine had a morphine-sparing effect after THA, even when morphine was combined with multimodal systemic analgesia. It also facilitated rehabilitation at 1 mo and decreased postoperative chronic pain up to 6 mo after surgery.
