Electrochemical treatment of alkaline nuclear wastes (1996)

Large quantities of highly radioactive waste have been generated throughout the Department of Energy complex over the past 50 years as a result of the production of special nuclear materials for defense and space programs. These wastes have been stored in underground tanks. Some of the tanks have developed cracks that have allowed waste to leak out of the primary tank. Many of the tanks are operating beyond their design life. Processes are being developed to remove the waste from the storage tanks and permanently dispose of it in engineered wasteforms. The bulk of the radioactivity will be concentrated into approximately 1% of the total waste volume and vitrified. The highly radioactive borosilicate glass wasteform will be placed in the federal repository. The remaining waste, which still contains low concentrations of radioactivity, will be incorporated into a low-level wasteform (e.g., cement, glass, ceramic, polymer, etc.) and placed in a near surface facility at the DOE site. Electrochemical-based processes are being evaluated to destroy organic compounds that impact radionuclide separations processes, to destroy or to remove hazardous species in the waste such as nitrates, nitrites, hazardous metals, and radionuclides that can impact wasteform production and characteristics, recovery chemicals of value suchmore » as sodium hydroxide (caustic) that can be recycled. Major benefits of such processes include the destruction or removal of hazardous species, waste volume reduction and the recovery of valuable chemicals contained in the waste.« less
Goal-Oriented Rectification of Camera-Based Document Images (2010)

Document digitization with either flatbed scanners or camera-based systems results in document images which often suffer from warping and perspective distortions that deteriorate the performance of current OCR approaches. In this paper, we present a goal-oriented rectification methodology to compensate for undesirable document image distortions aiming to improve the OCR result. Our approach relies upon a coarse-to-fine strategy. First, a coarse rectification is accomplished with the aid of a computationally low cost transformation which addresses the projection of a curved surface to a 2-D rectangular area. The projection of the curved surface on the plane is guided only by the textual content's appearance in the document image while incorporating a transformation which does not depend on specific model primitives or camera setup parameters. Second, pose normalization is applied on the word level aiming to restore all the local distortions of the document image. Experimental results on various document images with a variety of distortions demonstrate the robustness and effectiveness of the proposed rectification methodology using a consistent evaluation methodology that encounters OCR accuracy and a newly introduced measure using a semi-automatic procedure.

Moreover the complexity of the proposed method is considerably low. The related areas in the log files are determined for mining stage. Then, by using the association rules method the interesting patterns are extracted for consequent goals. In the result of this study, knowledge extraction was performed by proposed method. The significant and pure knowledge is contributed to structural organization of website. Besides, web site development and about the availability of the site to give advice to managers and designers are available.
Distributed Network-Channel Codes Design with Short Cycles Removal (2012)

In this paper, we address short cycle effects in the distributed low density generator matrix (LDGM) codes. As a codeword is formed from various nodes, the decentralized code construction makes it difficult to eliminate short cycles, resulting in a degraded code performance. To mitigate this effect, we propose a distributed algorithm which can eliminate short cycles within the network. The complexity of the proposed algorithm is a linear function of the number of relay nodes in the network. The simulation results show that the code performance can lower the error floor of irregular LDGM codes significantly, when all short cycles have been removed.

Phase II study of bevacizumab and erlotinib in treatment-naïve elderly patients (older than age 65) with advanced non-small cell lung cancer (NSCLC). (2010)

e18019 Background: The median age of newly diagnosed NSCLC patients (pts) in the United States is 71 and hence more than 60% of the pts will be 65 years of age or older. However, the elderly are under represented in clinical trials. The ‘fit elderly' (PS 0-1) derive the same level of benefit from systemic therapy as others but with a lower tolerance for toxicities. Innovative treatment strategies with less toxicity are, therefore, needed. This study explores the efficacy and tolerability of an ‘all-biologic' therapy in treatment-naïve elderly pts with advanced NSCLC. Methods: Fit elderly pts (≥70 years of age) with treatment-naïve stage IV or IIIB (malignant pleural effusion [MPE]) were treated with full dose erlotinib (150 mg/d) and bevacizumab (15 mg/kg Q 3 ks) in 21 day cycles. Progression Free Survival (PFS) was the primary endpoint. EGFR status was not required for enrollment. Imaging was performed every 2 cycles. Attributable grade 3 and 4 adverse events (AEs) were documented. Results: To date, 24 evaluable pts have been enrolled. Median age is 75 (range: 70-84). Fifteen pts (63%) have ECOG PS of 1. Five pts have stage IIIB disease. Kaplan-Meier estimate of median time from starting therapy to going off protocol is 4.8 months (95% confidence interval = 1.9-6.7). Of the 17 pts now off protocol, the median number of cycles is 4 (range: 1-23). Seven pts are currently on protocol, (range 3 to 38 cycles). For the first 15 pts on study, drug-related grade 3 (G3) and 4 (G4) AEs include hypertension (G3: 3 pts), fatigue (G3: 1 pt), rash (G3: 3 pts), diarrhea (1 G3 and 1 G4), anorexia (G3: 1 pt), and infection with neutropenia (G3: 1 pt). Five pts had partial response, four confirmed. Eleven pts had stable disease, four had progressive disease, and one was not evaluated. The response status of three pts is still pending. The estimated median PFS for all patients is 6.4 months (95% confidence interval 3.6-14.9 months). The estimated one year OS is 63.9% (95% CI = 33.6%-83.2%). Median OS has not been reached. Conclusions: Our data suggest that an all biologic combination with erlotinib and bevacizumab appears to be effective and well tolerated for the first-line management of elderly patients with advanced NSCLC.

Control of Spin-Wave Damping in YIG Using Spin Currents from Topological Insulators (2019)

Yttrium iron garnet (YIG) is a material with unique properties that make it very attractive for use in microwave applications, such as frequency-selective limiters and logic processing. However, the decay of a spin wave's amplitude as it propagates in the material curbs the use of YIG in practical applications. To surmount this limitation, in this study the surface spin currents of a topological insulator are used to enhance the spin-wave amplitude in adjacent YIG. In addition, interesting properties of magnons are observed and investigated, to advance spintronics.

Biochemically important reactions of 2-furylethylenes. Characterization of the reactivity towards thiols (1982)

Reactions of 1-(5-R 1 -2-furyl)-2-R 2 ,R 3 -ethylenes with thiols were investigated in aqueous solutions at pseudomonomolecular conditions and 25 °C. The obtained kinetic dependences made it possible to calculate the second order rate constants (1 mol -1 s -1 ). The reactivity of the studied 2-furylethylenes increases with the increasing electron-accepting effect of substituents varying both in position 5 of the furan and 2 of the exocyclic double bond. The reactivity of thiols towards 2-furylethylenes was found to raise with their increasing basicity.

Transient CFD Simulation of Exhaust Gas Recirculation Coolers for Further Structural Analyses (2009)

&lt;div class="htmlview paragraph"&gt;Exhaust Gas Recirculation coolers (EGR) have to withstand high thermal stresses due to large temperature gradients between the hot exhaust gas and the coolant. For the conceptual design of non-existing models in the early development phases, a simulation method was developed for the virtual validation of temperature cycle testing. In this work, a conjugate heat transfer analysis of a shell and tube type EGR cooler is carried out using Computational Fluid Dynamics (CFD) and the resulting structural temperatures are subsequently mapped to a Finite Element (FE) model for further structural analysis. This allows a complete and accurate thermal and structural analysis of component designs. The methodology has been developed and validated for temperature cycle loading tests. Experimental and simulation results are in good agreement, thereby allowing the successful virtual design and optimization of EGR coolers.&lt;/div&gt;
Synthesis of a Tri- and Tetrasaccharide Fragment Specific for the Shigella flexneri Serotype 5a O-Antigen. A Reinvestigation (1999)

ABSTRACT Stereocontrolled, stepwise synthesis of methyl α-L-rhamnopyranosyl-(1→2)-[α-D-glucopyranosyl-(1→3)]-α-L-rhamnopyranoside (A(E)B, 1) and methyl 2-acetamido-2-deoxy-β-D-glucopyranosyl-(1→2)-α-L-rhamnopyranosyl-(1→2)-[α-D-glucopyranosyl-(1→3)]-α-L-rhamnopyranoside (DA(E)B, 2) is described; these constitute the methyl glycosides of fragments of the O-specific polysaccharide of Shigella flexneri serotype 5a. Two routes to trisaccharide 1 were considered. Route 1 involved the coupling of a precursor to residue A and a disaccharide EB, whereas route 2 was based on the condensation of a precursor to residue E and a disaccharide AB. Rather surprisingly, the latter afforded the β-anomer of 1, namely methyl α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→3)]-α-L-rhamnopyranoside as the major product. Route 1 was preferred. Overall, several observations made during this study suggested that, for the construction of higher fragments, a suitable precursor to rhamnose A would require protecting groups of low bulkiness at position 3 and 4. Therefore, the 2-O-acetyl-3,4-di-O-allyl-α-L-rhamnopyranosyl trichloroacetimidate (35) was the precursor of choice to residue A in the synthesis of the tetrasaccharide 2. The condensation product of 35 and methyl 2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl-4-O-benzyl-α-L-rhamnopyranoside was selectively deacylated and condensed to 2-trichloroacetamido-3,4,6-tri-O-acetyl-2-deoxy-α-D-glucopyranosyl trichloroacetimidate to afford the corresponding fully protected tetrasaccharide 45. Controlled stepwise deprotection of the latter proceeded smoothly to afford the target 2. It should be emphasised that the preparation of 45 was not straightforward, several donors and coupling conditions that were tested resulted only in the complete recovery of the acceptor. Distortion of several signals in the 13C NMR spectra of the fully or partially protected tetrasaccharide intermediates suggested that steric hindrance, added to the known low reactivity of HO-2 of rhamnosyl acceptors, probably played a major role in the outcome of the glycosidation attempts.
Numerical Treatment of Defective Boundary Conditions for the Navier--Stokes Equations (2002)

We present a formulation for accommodating defective boundary conditions for the incompressible Navier--Stokes equations where only averaged values are prescribed on measurable portions of the boundary. In particular we consider the case where the flow rate is imposed on several domain sections. This methodology has an interesting application in the numerical simulation of flow in blood vessels, when only a reduced set of boundary data are generally available for the upstream and downstream sections.
Toward standardized mapping for left atrial analysis and cardiac ablation guidance (2014)

In catheter-based cardiac ablation, the pulmonary vein ostia are important landmarks for guiding the ablation procedure, and for this reason, have been the focus of many studies quantifying their size, structure, and variability. Analysis of pulmonary vein structure, however, has been limited by the lack of a standardized reference space for population based studies. Standardized maps are important tools for characterizing anatomic variability across subjects with the goal of separating normal inter-subject variability from abnormal variability associated with disease. In this work, we describe a novel technique for computing flat maps of left atrial anatomy in a standardized space. A flat map of left atrial anatomy is created by casting a single ray through the volume and systematically rotating the camera viewpoint to obtain the entire field of view. The technique is validated by assessing preservation of relative surface areas and distances between the original 3D geometry and the flat map geometry. The proposed methodology is demonstrated on 10 subjects which are subsequently combined to form a probabilistic map of anatomic location for each of the pulmonary vein ostia and the boundary of the left atrial appendage. The probabilistic map demonstrates that the location of the inferior ostia have higher variability than the superior ostia and the variability of the left atrial appendage is similar to the superior pulmonary veins. This technique could also have potential application in mapping electrophysiology data, radio-frequency ablation burns, or treatment planning in cardiac ablation therapy.

Quantifying uncertainties due to optical potentials in one-neutron knockout reactions (2023)

One-neutron knockout reactions have been widely used to extract information about the single-particle structure of nuclei from the valley of stability to the drip lines. The interpretation of knockout data relies on reaction models, where the uncertainties are typically not accounted for. In this work, we quantify uncertainties of optical potentials used in these reaction models and propagate them, for the first time, to knockout observables using a Bayesian analysis. We study two reactions in the present paper, the first of which involves a loosely bound halo projectile, $^{11}\mathrm{Be}$, and the second a tightly bound projectile, $^{12}\mathrm{C}$. We first quantify the parametric uncertainties associated with phenomenological optical potentials. Complementing this approach, we also quantify the model uncertainties associated with the chiral forces that can be used to construct microscopic optical potentials. For the phenomenological study, we investigate the impact of the imaginary terms of the optical potential on the breakup and stripping components of the knockout cross sections as well as the impact of the angular range. For the $^{11}\mathrm{Be}$ case, the theoretical uncertainty from the phenomenological method is on the order of the experimental uncertainty of the knockout observables; however, for the $^{12}\mathrm{C}$ case, the theoretical uncertainty is significantly larger. The widths of the uncertainty bands for the knockout observables obtained for the microscopic study and the phenomenological approach are of similar orders of magnitude. Based on this work we conclude that structure information inferred from the ratio of the knockout cross sections will carry a theoretical uncertainty of at least $20%$ for halo nuclei and at least $40%$ for tightly bound nuclei.
Structural characterization of Zn1−xCoxSe epilayers on GaAs(001) (1989)

We have grown a Co-based diluted magnetic semiconductor, the wide-gap compound Zn1−xCoxSe, by molecular-beam epitaxy on GaAs(001) substrates. We report here a detailed study of the structure and crystalline quality of these epilayers as obtained from a variety of x-ray diffraction and transmission electron microscopy (TEM) techniques. The films grow as (001) single-crystal zinc-blende epilayers which exhibit some degree of tetragonal distortion for the full range of Co concentrations (x≲0.1) and thicknesses (0.1–2.6 μm) studied. X-ray double-crystal rocking curve and topography measurements show that the crystalline quality of the thinner films (0.3 μm) approaches that of the GaAs substrates. Cross-sectional and plane-view TEM results indicate a low dislocation density and the absence of twin formation within the epilayers. High-resolution lattice images show that the interface between the epilayer and substrate is coherent and atomically abrupt.

Amphiphilic Block Copolymers as Bile Acid Sorbents:  2. Polystyrene-b-poly(N,N,N-trimethylammoniumethylene acrylamide chloride):  Self-Assembly and Application to Serum Cholesterol Reduction (2001)

This paper presents morphological studies and preliminary bile salt binding properties of the new amphiphilic diblock copolymer polystyrene-b-poly(N,N,N-trimethylammoniumethylene acrylamide chloride) (PS-b-PTMEACl)1 (see Figure 1), a derivative of PS-b-poly(tert-butylacrylate) (PS-b-PtBuA). In an aqueous environment, PS-b-PTMEACl forms simple spheres (∼20 nm diameter), large compound micelles (>100 nm diameter), and larger, more complex architectures as presented and discussed below. The colloidal stability with respect to sodium chloride and as a function of particle concentration is also considered. Finally, PS-b-PTMEACl aggregates were prepared and tested as an alternative to the commercially available bile salt sequestrant resins that target coronary heart disease due to elevated cholesterol levels. Electron micrographs were employed to visualize the colloid-based polyelectrolyte−biosurfactant interaction and chromatographic separation analytical methods were used to quantify the sequestration. The results indicate that although at this preliminary stage they require laborious preparation, self-assembled aggregates may present an interesting alternative to the clinically used bile salt sequestrants.
