The blanket interface to TSTA (1988)

The requirements of tritium technology are centered in three main areas, (1) fuel processing, (2) breeder tritium extraction, and (3) tritium containment. The Tritium Systems Test Assembly (TSTA) now in operation at Los Alamos National Laboratory (LANL) is dedicated to developing and demonstrating the tritium technology for fuel processing and containment. TSTA is the only fusion fuel processing facility that can operate in a continuous closed-loop mode. The tritium throughput of TSTA is 1000 g/d. However, TSTA does not have a blanket interface system. The authors have initiated a study to define a Breeder Blanket Interface (BBIO) for TSTA. The first step of the work is to define the condition of the gaseous tritium stream from the blanket tritium recovery system. This report summarizes this part of the work for one particular blanket concept, i.e., a self-cooled lithium blanket. The total gas throughput, the hydrogen to tritium ratio, the corrosive chemicals, and the radionuclides are defined. Various methods of tritium recovery from liquid lithium were assessed: yttrium gettering, permeation windows, and molten salt extraction. The authors' evaluation concluded that the best method was molten salt extraction.
Development of advanced electron holographic techniques and application to industrial materials and devices (2013)

The development of a transmission electron microscope equipped with a field emission gun paved the way for electron holography to be put to practical use in various fields. In this paper, we review three advanced electron holography techniques: on-line real-time electron holography, three-dimensional (3D) tomographic holography and phase-shifting electron holography, which are becoming important techniques for materials science and device engineering. We also describe some applications of electron holography to the analysis of industrial materials and devices: GaAs compound semiconductors, solid oxide fuel cells and all-solid-state lithium ion batteries.
Algorithmic, architectural, and beam pattern issues of sidelobe cancellation (1989)

Various important issues concerning the sidelobe cancellation (SLC) approach for suppressing sidelobe interference signals in radar are investigated. The concepts are presented in a tutorial manner and include: formulating the calculation of the complex weights for the auxiliary channels as an exact least-squares (LS) problem; computing the LS weights using orthogonal transformation for improved numerical accuracy; and mapping orthogonalization-based algorithms onto systolic arrays. The problem of excessive degrees of freedom (EDOF) associated with utilizing too many auxiliary elements when a relatively small number of jammers are present, is also considered. A divisionless orthogonalization-based algorithm is presented for the computation of the auxiliary weights. Many of these issues have previously been either implicitly stated or only individually addressed in various sources by a number of researchers. Besides showing simulation results and the divisionless procedure for obtaining the final auxiliary weights, a major consideration was to present all of the aforementioned concepts in a coherent and unified framework.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Clinical Effect of a Single Pulsed Dye Laser Treatment of Fresh Surgical Scars: Randomized Controlled Trial (2008)

A single pulsed dye laser treatment at the time of suture removal does not appear to have a beneficial effect on clinical scar appearance. The point of minimal benefit for such laser treatments may lie somewhere between one and three treatments.
Minimally Invasive Cardiac Valve Surgery Improves Patient Satisfaction While Reducing Costs of Cardiac Valve Replacement and Repair (1997)

Minimally invasive aortic and mitral valve surgery in patients without coronary disease can be done safely and accurately through small incisions. Patient satisfaction is up, return to normality is higher, and requirement for postrehabilitation services is less. In addition, the charges are approximately 20% less. These results serve as a paradigm for the future in terms of valve surgery in the managed care environment.
Dimethyl Ether in Diesel Engines: Progress and Perspectives (2000)

A review of recent developments related to the use of dimethyl ether (DME) in engines is presented. Research work discussed is in the areas of engine performance and emissions, fuel injection systems, spray and ignition delay, and detailed chemical kinetic modeling. DME’s properties and safety aspects are discussed. A simplified theoretical explanation of the emissions behavior of DME is presented. A discussion is presented proposing DME as a significant factor in the future international energy picture. Due to its beneficial combustion properties, possibility of production from a variety of sources, and usefulness as a chemical feed stock, DME can be used in a variety of applications in addition to transportation.
Gryphon: A Feasible Horizontal Takeoff Next Generation Architecture Concept (2004)

NASA’s Next Generation Launch Technology (NGLT) program recently funded studies of the Gryphon launch architecture. Gryphon combines existing technologies with moderate propulsion advancements and a design for operations approach into a unique, aircraft-like architecture. A joint NASA/industry team was assembled by NGLT’s Systems Analysis Project to assess the Gryphon concept and produce a conceptual design to specific performance, reliability, safety, and life cycle cost goals while meeting NASA and DoD requirements. The effort demonstrated the fundamental feasibility of the architecture. This paper describes the study, outlines the architecture’s features and benefits, and highlights the critical issues identified for further study.
Endoscopic Retroperitoneal Nephrectomy (2000)

Purpose: We describe modifications of the retroperitoneoscopic approach to the kidney, including the use of 2-mm instrumentation and prone positioning. Patients and Methods: Twenty-one children (13 girls, 8 boys; mean age 2.1 years) have undergone retroperitoneoscopic dissection in the prone position. An inflatable dissecting device was inserted into the retroperitoneum through a small incision at the lateral border of the sacrospinalis muscle, just below the costovertebral angle. After inflation, the dissecting device was replaced with a 5-mm cannula, the pneumoretroperitoneum was maintained with CO2 insufflation, and two 2-mm trocars were placed with endoscopic guidance. Dissection was performed using 2-mm instrumentation, and the specimen was extracted through the site of the largest port. Results: The children underwent nephrectomy, heminephrectomy, or total nephroureterectomy for chronic pyelonephritis with minimal function, reflux or obstruction with nonfunctioning kidney or moiety, multicystic dysplastic kidney, upper pole dysplastic moiety with associated ureterocele, or dysplastic kidney with a vaginal ectopic ureter. The mean operative time for the retroperitoneoscopic dissection was 142 minutes with an estimated blood loss of <15 mL. Conclusions: Several modifications to the retroperitoneal approach, including the use of prone positioning and 2-mm instrumentation, provide unobstructed viewing of the kidney and renal hilum and facilitate dissection in a small working space. These modifications may improve the safety and efficacy of this technique in children.
Towards (scalable) quantum simulations in ion traps (2007)

Experiments directed towards the development of an analogue quantum simulator based on trapped atomic magnesium ions are described. We report on the required initialization including ground state cooling of 25Mg+ ions for the first time—parallel to the group at NIST/Boulder. We discuss basic operations to implement quantum spin Hamiltonians like a one-dimensional quantum Ising model and some challenges to be addressed in reaching for larger scale and higher dimensional devices.
Discrete Element Method Simulations of Additively Manufactured Components With Integrated Particle Dampers (2021)

Abstract One major benefit of Additive Manufacturing is parts counts reduction. Several formerly distinct parts can be printed as one unit, reducing cost and weight. However, the interface between parts is often a major source of vibration damping, so eliminating interfaces can lead to fatigue failures. To alleviate this, researchers have been exploring the integration of damping features inside parts. Leaving a small pocket of unfused powder creates a particle damper. Particle dampers have long been known to suppress unwanted vibration. However they are highly complex and predicting their behavior is difficult. The particle damper literature often has contradictory claims, as what works best for one application does not work for another. Because the additive feedstock powder is much smaller (5–50 μm) than particles in typical particle dampers, it is difficult to draw conclusions from the existing literature to develop design guidelines. This papers reports on a Discrete Element Method (DEM) numerical simulation of additively manufactured cantilever beams with a small pocket of unfused powder. DEM explicitly simulates the motion of each particle and their interactions. Previously reported experiments with varying beam geometry showed nearly an order of magnitude difference in damping ratio depending on the location of the pocket along the beam. The simulation was able to accurately predict the damping ratio based on the input geometry. As a result, the correlated simulation tool can be used to optimize future designs. From the simulations, it was observed that particle-wall momentum exchange and particle-particle inelastic collisions appeared to be key contributors to the damping ratio. Additionally, a non-linear subharmonic motion of particles was observed, which suggests additional ways to improve performance.
De l'estimation de mouvement pour l'analyse temps réel de vidéos dans le domaine compressé (2007)

Directly analysing compressed video sequences requires accurate procedures to evaluate motion vectors. Our work focuses on a real time application processing these vectors. A statistical analysis of their spatial distribution makes it possible to select the appropriate filtering scheme. Then the related algorithms were implemented and validated on a corpus of surveillance sequences. Compared to previous publications, the overall result is a five time faster analysis.
Traumatic brain injury, coronary atherosclerosis and cardiovascular mortality (2015)

mTBI is associated with the severity of sub-clinical coronary atherosclerosis and independently predicts CV mortality.
A decision making module for cooperative collision warning systems using Vehicular Ad-Hoc Networks (2013)

Using a Vehicular Ad-Hoc Network (VANET) communication for cooperative collision warning system can increase safety, convenience and efficiency in driving. Intelligent vehicles can collect information about the driving environment, the driver situation and more importantly other vehicles' information using wireless communication. However, deciding what data to considered, what data to ignore and if and what action should be taken in different situations is a significant issue. In this work, we explore the use of a decision making module for accident situations which processes information from VANET communication and advises the driver based on the situation. Our decision making algorithm is a simple and effective algorithm that can be implement in each vehicle to assist the driver in certain situations. Rerouting to avoid traffic congestion caused by the accident is the major part of our decision making algorithm. This module has been implemented and evaluated using the Veins simulation.
Differential miRNA expression profiles in variants of papillary thyroid carcinoma and encapsulated follicular thyroid tumours (2009)

We conclude that analysis of a set of five selected miRNAS distinguish common variants of PTC from FA/MNG but failed to be a useful diagnostic method in individual and doubtful cases, especially in the differential diagnosis of encapsulated follicular thyroid tumours.
Hydrogen-Induced Lateral Growth of Nickel Coating on Ba[sub 3]Co[sub 2]Fe[sub 24]O[sub 41](Co[sub 2]Z)-Based Hexaferrite during the Electroplating of Multilayer Chip Inductors (2002)

In the present paper, electrical measurements, air-annealing experiments, and X-ray photoelectron spectroscopy (XPS) were used to study the lateral growth of nickel coating on the ceramics substrate during electroplating of hexaferrite multilayer chip inductors (MLCI). It was found that resistivity of the ferrite and inductance of MLCI decreased continuously during the electroplating. The lateral growth of metal coating occurred only after a certain time of electroplating, but not immediately. XPS analysis showed that a large part of on the ferrite surface had been reduced to during 20 min of nickel electroplating. However, the resistance-degraded specimens can be restored through 2 h of air annealing at 650°C during which all the was reoxidized to Based on the results obtained, it was concluded that reduction to induced by hydrogen during electroplating must be responsible for the functional degradation of the ferrite, which then resulted in the lateral growth of metal coating on the ceramics surface. © 2002 The Electrochemical Society.

Optimal wavefront estimation and control using adaptive techniques (2012)

Space-based coronagraphs for earth-like planet detection will require focal plane wavefront control to achieve the necessary contrast levels. These correction algorithms are iterative and require an estimate of the electric field at the science camera. In order to maximize science time the correction time must be minimized, which means reducing the number of exposures required for correction. This also means minimizing the number of iterations and the number of exposures per iteration to achieve a targeted contrast. The ideal choice is to use fewer exposures to estimate the electric field with the same level of accuracy. We demonstrate an optimal estimator that uses prior knowledge to create the estimate of the electric field. The performance of this method is compared to a pairwise estimator which is designed to give the least-squares minimal error. This allows us to evaluate the number of images necessary to achieve a contrast target.
Gelatin Particle-Stabilized High Internal Phase Emulsions as Nutraceutical Containers (2014)

In this paper, we report for the first time the use of a well-dispersed gelatin particle as a representative of natural and biocompatible materials to be an effective particle stabilizer for high internal phase emulsion (HIPE) formulation. Fairly monodispersed gelatin particles (∼200 nm) were synthesized through a two-step desolvation method and characterized by dynamic light scattering, ζ-potential measurements, scanning electron microscopy, and atomic force microscopy. Those protein latexes were then used as sole emulsifiers to fabricate stable oil-in-water Pickering HIPEs at different concentrations, pH conditions, and homogenization times. Most of the gelatin particles were irreversibly adsorbed at the oil-water interface to hinder droplet coalescence, such that Pickering HIPEs can be formed by a small amount of gelatin particles (as low as 0.5 wt % in the water phase) at pH far away from the isoelectric point of the gelatin particles. In addition, increasing homogenization time led to narrow size distribution of droplets, and high particle concentration resulted in more solidlike Pickering HIPEs. In vitro controlled-release experiments revealed that the release of the encapsulated β-carotene can be tuned by manipulating the concentration of gelatin particles in the formulation, suggesting that the stable and narrow-size-distributed gelatin-stabilized HIPEs had potential in functional food and pharmaceutical applications.

Plastic Surgery Wars (1988)

<i>To the Editor</i>.—I laud Dr Jack Anderson's professed goal of ending the plastic surgery wars in his commentary in theArchives.<sup>1</sup>Certainly, as he concludes, it is not an impossible dream for men of good will. I do take issue, however, with his proposed solution, for it betrays what is really wrong with cosmetic surgery today. The so-called turf wars are an embarrassment to all and unseemly behavior for professionals of dignity, but the real subject of our concern should be the well-being of our patients. They care not a whit about our squabbles, but want only quality care. How is a poor patient to select a well-trained surgeon from the advice available through media ballyhoo? The biggest advertisements, the fanciest office, the slickest sales force, or the presence of a celebrity in the waiting room are poor criteria from which to select a surgeon. The issue of
Exciton-Polaritons with Magnetic and Electric Character in All-Dielectric Metasurfaces (2020)

Exciton–polaritons are hybrids of light and matter formed at the strong coupling regime that exhibit interesting phenomena such as enhanced transport, long-range energy transfer, and nonlinear response. These properties make exciton–polaritons very promising quasiparticles for the development of novel optoelectronic applications in the so-called polaritonic devices. However, strong coupling is significantly damped by the absorption losses of the system, which lead to short-lived exciton–polaritons. Here, we demonstrate strong coupling between excitons in organic molecules and all-dielectric metasurfaces formed by arrays of polycrystalline silicon nanoparticles supporting Mie surface lattice resonances (MSLRs). Compared to Mie resonances in individual nanoparticles, MSLRs have extended mode volumes and much larger quality factors, which enables to achieve collective strong coupling with very large coupling strengths and Rabi energies. Moreover, the presence of electric and magnetic Mie resonances in high refractive index dielectric nanoparticles introduces a new degree of freedom in light–matter interaction. We show the hybridization of excitons with electric and magnetic MSLRs, to form exciton–polaritons with an electric or magnetic character. Our results demonstrate the potential of all-dielectric metasurfaces as novel platform to investigate and manipulate exciton–polaritons in low-loss polaritonic devices.

Mechanism of outer membrane destabilization by global reduction of protein content (2023)

The outer membrane (OM) is a selective permeability barrier that contributes to the intrinsic antibiotic resistance of Gram-negative bacteria. Biophysical characterization of the roles of the component proteins, lipopolysaccharides, and phospholipids is limited by both the essentiality of the OM and its asymmetrical organization. In this study, we dramatically change OM physiology by limiting the protein content, which requires phospholipid localization to the outer leaflet and thus disrupts OM asymmetry. By characterizing the perturbed OM of various mutants, we provide novel insight into the links among OM composition, OM stiffness, and cell shape regulation. These findings deepen our understanding of bacterial cell envelope biology and provide a platform for further interrogation of OM properties.
ENTRY CHARACTERISTICS OF PRACTICAL WORKPLACE AEROSOL SAMPLERS IN RELATION TO THE ISO RECOMMENDATIONS (1990)

In recent years, new sets of criteria for health-related aerosol sampling in workplaces have been proposed by, for example, the International Standards Organizations (ISO) and the American Conference of Governmental Industrial Hygienists (ACGIH). It is therefore timely to examine the performances of workplace aerosol samplers, both instruments that have been used in the past and ones which are beginning to emerge, in the light of these recommendations. This paper describes the results and conclusions from a study of dust samplers with a view to their possible applications in the mining industry. Their performances are assessed with special reference to their entry efficiencies, based on the philosophy contained in the most up-to-date ISO recommendations, in particular with regard to the concept of inhalability (or inspirability).
Oligomerization of Butene Mixture over NiO/Mesoporous Aluminosilicate Catalyst (2018)

This study is aimed at preparing C8–C16 alkene through oligomerization of a butene mixture using nickel oxide supported on mesoporous aluminosilicate. Mesoporous aluminosilicate with an ordered structure was successfully synthesized from HZSM-5 zeolite by combining a top-down and a bottom-up method. MMZZSM-5 catalyst showed much higher butene conversion and C8–C16 yield in the butene oligomerization reaction than those with HZSM-5. This is attributed to the pore geometry of MMZZSM-5, which is more beneficial for internal diffusion of reactants, reaction intermediates, and products. The ordered channel-like mesopores were maintained after the nickel-loading on MMZZSM-5. The yield for C8–C16 hydrocarbons over NiO/MMZZSM-5 was higher than that of MMZZSM-5 catalyst, which seemed to be due to higher acid strength from a higher ratio of Lewis acid to Brønsted acid. The present study reveals that a mesoporous NiO/MMZZSM-5 catalyst with a large amount of Lewis acid sites is one of the potential catalysts for efficient generation of aviation fuel through the butene oligomerization.
