High‐resolution esophageal manometry: addressing thermal drift of the manoscan system (2011)

Thermal effect is well compensated in the current operation of the system but baseline drift is not well recognized or addressed. Incorporation of a linear correction into current software would improve accuracy without impact on ease of use.
Testing Multitheoretical, Multilevel Hypotheses About Organizational Networks: An Analytic Framework and Empirical Example (2006)

Network forms of organization, unlike hierarchies or marketplaces, are agile and are constantly adapting as new links are added and dysfunctional ones dropped. We review some of the theoretical and methodological accomplishments and challenges of contemporary research on organizational networks. We then offer an analytic framework that can be used to specify and statistically test simultaneously multilevel, multitheoretical hypotheses about the structural tendencies of organizational networks. We conclude with an empirical study illustrating some of the capabilities of this framework.
Recovering human body con .gurations:combining segmentation and recognition (2004)

The goal of this work is to detect a human figure image and localize his joints and limbs along with their associated pixel masks. In this work we attempt to tackle this problem in a general setting. The dataset we use is a collection of sports news photographs of baseball players, varying dramatically in pose and clothing. The approach that we take is to use segmentation to guide our recognition algorithm to salient bits of the image. We use this segmentation approach to build limb and torso detectors, the outputs of which are assembled into human figures. We present quantitative results on torso localization, in addition to shortlisted full body configurations.
Viability of long-term cryopreserved human saphenous veins. (1990)

The feasibility of maintaining long-term viability of human venous allografts by cryopreservation has been investigated. Segments of vein were obtained from 85 patients undergoing a stripping operation for varicose veins. The venous segments were immersed in a dimethylsulfoxide 15% solution, deep frozen at -196 degrees C in liquid nitrogen and preserved for a duration of 1 week to 24 months. Light microscopy (n = 126) failed to demonstrate striking differences between control veins and any of the cryopreserved veins. The types of damage observed at scanning electron microscopy included endothelial cell separation, endothelial cell loss, exposed basement membrane and exposed fibrillar collagen, which were graded on a scale. The score for short term (less than 3 weeks) stored veins was 8.1 +/- 0.9 (mean +/- SEM) and did not differ from the long-term (greater than 10 weeks) stored veins score (6.3 +/- 1.0, p NS). The tissue enzymes LDH, GOT, GPT, CPK were measured in the frozen vein groups (n = 115) after thawing to room temperature. Cryopreservation did not alter any of the tissue enzymes measured when compared to controls. Endothelial fibrinolytic activity (FA) of 58 venous segments cryopreserved for a mean duration of 20 months was 6136.4 +/- 292.1 Tissue Activator Units (TAU) and did not differ from FA of 11 controls (5989.1 +/- 696.8 TAU). Synthesis of 6-Keto-PGF1-alpha-2, a stable breakdown product of PGI2, measured in 10 venous segments cryopreserved for 10 months, was significantly higher than in 13 veins stored in saline for 12 hours at 4 degrees C (2.8 +/- 0.4 vs 0.4 +/- 0.1 PG ml-1mg-1min-1, respectively; p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
Audio Elements Based Auditory Scene Segmentation (2006)

Auditory scene segmentation is an important step in the process of high-level semantic inference from audio data streams, and in particular, a prerequisite for auditory scene categorization. In this paper, we analyze the limits of previous works on auditory scene segmentation, and then propose a novel method that, conceptually, is inspired by the ideas used in text and video scene segmentation, and is based on an analysis of audio elements and key audio elements, which can be seen as equivalents to the words and keywords in a text document, respectively. Experiments performed on 1.5 hours of audio data indicate that the proposed approach is promising.
Discriminating spinal deformity employing centroids difference on the moiré images (2001)

Abstract Spinal deformities, a condition in which the spine deviates to the left or right from the midline, are on the rise, particularly among elementary and middle‐school students. Group diagnoses are being performed at schools for the purpose of early detection, but the burden on physicians is high due to the need to process many images. Automated diagnosis using computers is highly desirable from the standpoint of treatment. In this paper the authors establish a left–right rectangular processing region in a moiré image of a human back, then propose a method to automatically detect spinal deformities with the differences in the centroid positions as a feature. Using an approximately symmetrical reference axis which closely follows the midline of a person, and the amount of the feature from the centroid position of the left–right rectangular region as centered on the reference axis, the authors' method discriminates between normal cases and abnormal cases using a linear discrimination function on a two‐dimensional surface. If this kind of primary diagnosis of spinal deformities can be automated, group diagnosis in schools would be more efficient and useful. The authors use their method, perform discrimination tests on 120 normal and abnormal cases, and find a recognition rate of 87.9%. © 2001 Scripta Technica, Syst Comp Jpn, 32(7): 20–28, 2001
Adaptive Placement of Data Analysis Tasks For Staging Based In-Situ Processing (2021)

In-situ processing addresses the gap between speeds of computing and I/O capabilities by processing data close to the data source, i.e., on the same system as the data source (e.g., a simulation). However, the effective implementation of in-situ processing workflows requires the optimization of several design parameters such as where on the system workflow data analysis/visualization (ana/vis) as placed and how execution as well as the interaction and data exchanges between ana/vis are coordinated. For example, in the case of hybrid in-situ processing, interacting ana/vis may be tightly or loosely coupled depending on their placement, and this can lead to very different performance and scalability. A key challenge is deciding the most appropriate ana/vis placement, which depends on dynamic applications, workflow, and system characteristics that might change at runtime. In this paper, we present a framework to support online adaptive data analysis placement during the execution of an in-situ workflow. Specifically, the paper presents a model and architecture, and explores several data analysis placement strategies. Evaluation results show that dynamically choosing appropriate data analysis placement strategies can balance the benefits and overhead of different data analysis placement patterns to reduce in-situ processing time.
Influence of the free-energy functional form on simulated morphology of spinodally decomposing blends (2000)

The spinodal decomposition of a binary mixture has been studied within several mesoscopic models. It has been found that the form of the equilibrium free energy has a crucial effect on the morphological development in asymmetric blends. We have shown that the principal quantity that determines the topology of the interface (and type of morphology) is the equilibrium minority phase volume fraction, while the transition from bicontinuous to droplet morphology can be treated as a percolation. The concentration dependence of the square gradient coefficient attributed for the Flory-Huggins-de Gennes free energy has no significant influences on the average domain growth, but can be distinguished experimentally from its constant-coefficient alternative by measuring the maximum wave vector of the scattering intensity as a function of the minority phase volume fraction for spinodally decomposing asymmetric blends. The concentration dependence of the Onsager coefficient has the weak, systematic effect of slowing down the morphological development. The local shape of the interface is not affected considerably by the concentration dependence of the square gradient and Onsager coefficient.
Principles of Nerve Repair in Complex Wounds of the Upper Extremity (2015)

Peripheral nerve injuries are common in the setting of complex upper extremity trauma. Early identification of nerve injuries and intervention is critical for maximizing return of function. In this review, the principles of nerve injury, patient evaluation, and surgical management are discussed. An evidence-based approach to nerve reconstruction is reviewed, including the benefits and limitations of direct repair and nerve gap reconstruction with the use of autografts, processed nerve allografts, and conduits. Further, the principles and indications of commonly used nerve transfers in proximal nerve injuries are also addressed.

Elastically controlled manipulation of the magnetic order parameter and the metal-insulator transition in a manganite thin film (2014)

We measured the temperature dependence of the saturation magnetization $({M}_{s})$ of a $({\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Pr}}_{x}){}_{1\ensuremath{-}y}{\mathrm{Ca}}_{y}{\mathrm{MnO}}_{3}$ $(x\ensuremath{\sim}0.60$, $y\ensuremath{\sim}\mathrm{0.33})$ film as a function of applied bending stress. Stress producing a compressive strain of \ensuremath{-}0.01% along the magnetic easy axis increased the Curie temperature by \ensuremath{\sim}6 K and the metal-insulator transition by \ensuremath{\sim}4 K. Regardless of whether or not stress is applied to the film, magnetic ordering occurs at temperatures significantly higher than the metal-insulator-transition temperature. The magnetization of the sample at the temperature of the metal-insulator transition is approximately the site percolation threshold for a two-dimensional spin lattice.
Genomic structure analysis of promoter sequence of a mouse mu opioid receptor gene. (1994)

We have isolated mouse mu opioid receptor genomic clones (termed MOR) containing the entire amino acid coding sequence corresponding to rat MOR-1 cDNA, including additional 5' flanking sequence. The mouse MOR gene is > 53 kb long, and the coding sequence is divided by three introns, with exon junctions in codons 95 and 213 and between codons 386 and 387. The first intron is > 26 kb, the second is 0.8 kb, and the third is > 12 kb. Multiple transcription initiation sites were observed, with four major sites confirmed by 5' rapid amplification of cDNA ends and RNase protection located between 291 and 268 bp upstream of the translation start codon. Comparison of the 5' flanking sequence with a transcription factor database revealed putative cis-acting regulatory elements for transcription factors affected by cAMP, as well as those involved in the action of gluco- and mineralocorticoids, cytokines, and immune-cell-specific factors.
Optimization of Nonaqueous Electrolytes for Primary Lithium/Air Batteries Operated in Ambient Environment (2009)

The selection and optimization of nonaqueous electrolytes for ambient operations of lithium/air batteries have been studied. Organic solvents with a low volatility and low moisture absorption are necessary to minimize the change in electrolyte compositions and the reaction between lithium anode and water during the discharge process. It is also critical to make the electrolyte with a high polarity so that it can reduce wetting and flooding of the carbon-based air electrode and lead to improved battery performance. For ambient operations, the polarity of solvents outweighs the viscosity, ion conductivity, and oxygen solubility once these latter properties attain a certain reasonable level. Hence, a propylene carbonate/ethylene carbonate (PC/EC) mixture is the most feasible solvent system and lithium bis(trifluoromethanesulfonyl)imide the best salt for ambient operations of Li/air batteries, whose performance is relatively insensitive to PC/EC ratio and salt concentration.
Effects of the Polarizability and Packing Density of Transparent Oxide Films on Water Vapor Permeation (2005)

The tin oxide and silicon oxide films have been deposited on polycarbonate substrates as gas barrier films, using a thermal evaporation and ion beam assisted deposition process. The oxide films deposited by ion beam assisted deposition show a much lower water vapor transmission rate than those by thermal evaporation. The tin oxide films show a similar water vapor transmission rate to the silicon oxide films in thermal evaporation but a lower water vapor transmission rate in IBAD. These results are related to the fact that the permeation of water vapor with a large dipole moment is affected by the chemistry of oxides and the packing density of the oxide films. The permeation mechanism of water vapor through the oxide films is discussed in terms of the chemical interaction with water vapor and the microstructure of the oxide films. The chemical interaction of water vapor with oxide films has been investigated by the refractive index from ellipsometry and the OH group peak from X-ray photoelectron spectroscopy, and the microstructure of the composite oxide films was characterized using atomic force microscopy and a transmission electron microscope. The activation energy for water vapor permeation through the oxide films has also been measured in relation to the permeation mechanism of water vapor. The diffusivity of water vapor for the tin oxide films has been calculated from the time lag plot, and its implications are discussed.
Perceptual transparency from image deformation (2015)

Human vision has a remarkable ability to perceive two layers at the same retinal locations, a transparent layer in front of a background surface. Critical image cues to perceptual transparency, studied extensively in the past, are changes in luminance or color that could be caused by light absorptions and reflections by the front layer, but such image changes may not be clearly visible when the front layer consists of a pure transparent material such as water. Our daily experiences with transparent materials of this kind suggest that an alternative potential cue of visual transparency is image deformations of a background pattern caused by light refraction. Although previous studies have indicated that these image deformations, at least static ones, play little role in perceptual transparency, here we show that dynamic image deformations of the background pattern, which could be produced by light refraction on a moving liquid's surface, can produce a vivid impression of a transparent liquid layer without the aid of any other visual cues as to the presence of a transparent layer. Furthermore, a transparent liquid layer perceptually emerges even from a randomly generated dynamic image deformation as long as it is similar to real liquid deformations in its spatiotemporal frequency profile. Our findings indicate that the brain can perceptually infer the presence of "invisible" transparent liquids by analyzing the spatiotemporal structure of dynamic image deformation, for which it uses a relatively simple computation that does not require high-level knowledge about the detailed physics of liquid deformation.
Signatures of Multiband Effects in High-Harmonic Generation in Monolayer MoS2 (2022)

High-harmonic generation (HHG) in solids has been touted as a way to probe ultrafast dynamics and crystal symmetries in condensed matter systems. Here, we investigate the polarization properties of high-order harmonics generated in monolayer MoS_{2}, as a function of crystal orientation relative to the mid-infrared laser field polarization. At several different laser wavelengths we experimentally observe a prominent angular shift of the parallel-polarized odd harmonics for energies above approximately 3.5 eV, and our calculations indicate that this shift originates in subtle differences in the recombination dipole strengths involving multiple conduction bands. This observation is material specific and is in addition to the angular dependence imposed by the dynamical symmetry properties of the crystal interacting with the laser field, and may pave the way for probing the vectorial character of multiband recombination dipoles.
Results of an Innovative 100kW Induction Heater Prototype Testing (2013)

Industrial induction heating processes can contribute to the European Union (EU) energy saving goal of 20 percent before 2020. Induction manufacturers already propose many efficient solutions available at industrial scale. To improve induction devices for better energy efficiency, EDF R&D set up a French collaborative project called Innovative Solutions for Induction Systems (ISIS) with the financial support of the French National Research Agency (ANR). The objective of ISIS is to promote induction heating as a best available technology (BAT) and to develop innovative solutions to increase its efficiency. This paper reports the ISIS project innovations. The paper also discusses about the efficient heat conversion from the induction heating devices through the use of new auto-adaptive multi-coil power supply with low losses coils. An important aspect of this project is the recovery of fatally lost heat energy (cooling of the inductors). During the prototype testing, first the control algorithms of the multi-coil technology were successfully tested on a 100 kW 3-coils power supply. A homogenization technique is proposed to model a multi-strand coil and to use it in industrial setting. The multi-strand coils are now used only in low power residential applications such as induction cooking. A heat recovery test bench is built and equipped with a predictable function control (PFC) loop to fit with the production fluctuations. This paper also presents an analysis of the U.S. potential market for these new induction heating approaches and their applications in industries.
A signal-specific approach for reducing SAR-ADC power consumption (2013)

A novel power optimization technique, called adaptive tracking is proposed in this paper for successive approximation analog-to-digital converters aiming implantable device applications. A SAR-ADC can easily be equipped with the proposed tracking technique by a minor modification in its digital circuitry (SAR). This work relies on the similarity of consecutive sample values in band-limited bio-potentials. The proposed adaptive tracking scheme can reduce power consumption of a wide variety of SAR-ADCs. In particular, we show that the tracking scheme can save 30% of power in a conventional SAR-ADC, 31% of power in those using binary SAR-ADCs using a weighted DAC with split MSB capacitor, and 8% of power in those using charge sharing DAC.
PNP‐Pincer‐Type Phosphaalkene Complexes of Late Transition Metals (2016)

This account summarizes our recent studies on PNP-pincer-type phosphaalkene complexes. Phosphaalkenes with a P=C bond possess an extremely low-lying π* orbital and have a marked tendency to engage in strong π back-bonding with transition metals. This particular ligand property provides PNP-pincer complexes with unique structures and reactivities. 2,6-Bis(phosphaethenyl)pyridine leads to the isolation of coordinatively unsaturated complexes of Fe(I) and Cu(I); the former adopts a trigonal monopyramidal configuration, whereas the latter has a strong affinity for PF6- and SbF6- as non-coordinating anions. Unsymmetrical PNP-pincer-type phosphaalkene complexes of Ir(I) bearing a dearomatized pyridine unit instantly cleave the N-H bond of NH<sub>3</sub> and the C-H bond of MeCN at room temperature. The dearomatized iridium complexes catalyze the dehydrative coupling of amines with alcohols to afford N-alkylated amines and imines in high yields.
Design and Manufacture of an Original Equipment Manufacturer Deepwater Managed Pressure Drilling Integrated Solution (2018)

Abstract Objectives/Scope Industry deepwater exploration and development continues to encounter complex reservoir challenges, demanding an alternative to conventional drilling. Applied backpressure Managed Pressure Drilling has proven to be a solution suitable for similar challenges on land and shallow water. Some projects around the world have expanded the application to deepwater. The degree of complexity for such a solution in deepwater is such that it remains niche. To deliver a successful solution, operators have relied on integrating components from multiple providers to ensure a complete system. The package is customized for each drilling rig, further adding complexity to the integration exercise. Because each component of the system is delivered from separate suppliers, the certification of the system by an appropriate agency must then be approved on a case-by-case basis to guarantee insurability of the offshore drilling unit. Beyond certification, the ability to optimize the package was limited by barriers inherent in a multi-supplier solution. Methods, Procedures, Process In 2016, a drilling contractor requested an integrated deepwater MPD package, aimed at adding versatility to their rig fleet. A fully integrated, single Original Equipment Manufacturer solution was designed and manufactured to meet the objective of MPD enablement for a package designed to move throughout the fleet. The design, manufacture, install and system integrity test of all components for two drilling rigs took place over a 12-month period. The system was witnessed and certified by DNV GL. First field deployment took place in late 2017. Results, Observations, Conclusions This paper describes the complexities of delivering a fully integrated deepwater MPD package, including RCD, riser gas handling system, MPD control system and pressure and flow management hardware as a first artifact with DNV GL OS-E101 classification. Novel/Additive Information The solution described is an industry first complete OEM deepwater MPD system.
