The Role of Cardiac Ultrasound in Stem Cell Therapy (2009)

The role of cardiac ultrasound in evaluating and treating patients with stem cell therapy is reviewed. A number of ultrasound techniques can be used in the evaluation, therapy delivery, and follow-up of patients treated with stem cell therapy. These techniques include evaluation of myocardial systolic and diastolic function, perfusion, ischemia, viability, synchrony, and imaging targeted to specific cell types.
Performance of reiterated LMMSE filtering and coded radar waveforms (2008)

OFDM waveforms offer strong advantages for integrated communication and radar systems. Nevertheless they require filtering at the receiver that can serve for sidelobe suppression in order to avoid target masking. However unmasking is not the only concern, it is crucial to evaluate the filtering scheme both in terms of sidelobe suppression capability but also in terms of output signal to noise ratio. This last criterion is essential when aiming at detecting also weaker reflections. In this paper the theoretical performance of the reiterated filtering technique based on LMMSE is derived and compared to the matched filter. The unmasking capabilities are relevant, but also output power figures. Moreover the performance of reiterated LMMSE is evaluated for OFDM communication-encoded radar waveforms.
Minimal Test for Coupling Faults in Word-Oriented Memories (2002)

Most industrial memories have an external word-width of more than one bit. However, most published memory test algorithms assume 1-bit memories; they will not detect coupling faults between the cells of a word. This paper improves upon the state of the art in testing word-oriented memories by presenting a new method for detecting state coupling faults between cells of the same word, based on the use of m-out-of-n codes. The result is a reduction in test time, which varies between 26 and 38%.
Disturbance Effects On A Ground Based Precision Tracking System (1987)

A major concern when considering the design of a ground based precision tracking system, is the optical jitter that will result from various environmental disturbances. This paper considers disturbances including wind, angular seismic, linear seismic, gyroscope noise, electronics noise, and atmospheric turbulence. The disturbances may couple into a tracking system by applying forces or torques directly on the optical components, or by transmitting through the control loops which in turn place jitter into the optical path. The tracking system design can be altered by using different control system configurations to reject the expected disturbances. For instance, if seismic disturbances are large and expected to cause jitter in the optical train it may be desirable to add an autoalignment system to maintain dynamic optical train alignment. A further level of complexity is the selection of a reference for the autoalignment system. It might be a gyroscope stabilized mirror or simply a softly suspended mirror. This paper reports a trade study between the various disturbances and the various hardware configurations that result in some general guidelines when selecting the components in the design of a precision tracking system.
Design, Construction Details, and Preoperational Testing of an Argonne Fast Critical Facility (1966)

This report describes the component details and methods and procedures of construction of an Argonne fast reactor facility. Certain tests, and data resulting from such tests, have been included to illustrate structural stability. Accuracies of fits and alignment of mating parts, table surface flatness, precision leveling, etc., are given to indicate the reliability of the data taken during reactor experiments. The basic machine was designed and fabricated to tolerances that are consistent with large machine-tool fabrication. Further dimensional refinement would result in much higher cost with very little, if any, gain in reliability. The erection of the facility is discussed in a stepwise manner to provide a clear description of each part and how it fits the overall assembly. Safety and fail-safe features are explained in detail. Much of the design criteria was dictated by experience gained from the operation of ZPR-3. Matrix deflection behavior and magnitude were predictable through studies made on the ZPR-3 matrix loadings.
Radiation pressure acceleration by ultraintense laser pulses (2008)

The future applications of the short-duration, multi-MeV ion beams produced in the interaction of high-intensity laser pulses with solid targets will require improvements in the conversion efficiency, peak ion energy, beam monochromaticity, and collimation. Regimes based on Radiation Pressure Acceleration (RPA) might be the dominant ones at ultrahigh intensities and be most suitable for specific applications. This regime may be reached already with present-day intensities using circularly polarized (CP) pulses thanks to the suppression of fast electron generation, so that RPA dominates over sheath acceleration at any intensity. We present a brief review of previous work on RPA with CP pulses and a few recent results. Parametric studies in one dimension were performed to identify the optimal thickness of foil targets for RPA and to study the effect of a short-scalelength preplasma. Three-dimensional simulations showed the importance of ``flat-top'' radial intensity profiles to minimise the rarefaction of thin targets and to address the issue of angular momentum conservation and absorption.
Tight glycemic control in the ICU - is the earth flat? (2014)

Tight glycemic control in the ICU has been shown to reduce mortality in some but not all prospective randomized control trials. Confounding the interpretation of these studies are differences in how the control was achieved and underlying incidence of hypoglycemia, which can be expected to be affected by the introduction of continuous glucose monitoring (CGM). In this issue of Critical Care, a consensus panel provides a list of the research priorities they believe are needed for CGM to become routine practice in the ICU. We reflect on these recommendations and consider the implications for using CGM today.
Relationship of Testis Size and LH Levels with Incidence of Major Adverse Cardiovascular Events in Older Men with Sexual Dysfunction (2013)

Our data show that in SD subjects, TV and LH are associated with an adverse CV risk profile that mediate the higher TV-associated incidence of MACE. High LH levels are an independent marker of CV risk. Further studies are needed for clarifying determinants and mechanisms of testis enlargement that, beyond gonadotropins, could mediate the increased incidence of MACE.
Simulation of obliquely incident light propagation through a general twisted nematic liquid crystal cell by the Jones matrix technique (2000)

The simple Jones matrix technique was applied for finding intensity of obliquely incident light that passes through a plate of a uniaxial uniform medium that later was extended to general twisted nematic liquid crystal medium. Results of calculations were compared with the Berreman 44 matrix technique. Shown is the way of finding contrast viewing characteristics of nematic liquid-crystal displays. The obtained results are compared with experimental data.
Characterization of Steels Using a Revised Kinematic Hardening Model Incorporating Bauschinger Effect (2003)

A new variant of the nonlinear kinematic hardening model is proposed which accommodates both nonlinear and linear strain hardening during initial tensile loading and reduced elastic modulus during initial load reversal. It also incorporates the Bauschinger effect, as a function of prior tensile plastic strain, during the nonlinear compressive loading phase. The model is shown to fit experimental data from a total of five candidate gun steels. The numerical fits will be employed in subsequent work to predict residual stresses and fatigue lifetimes for autofrettaged tubes manufactured from the candidate steels.

Study of uranyl(VI) malonate complexation by time resolved laser-induced fluorescence spectroscopy (TRLFS) (2002)

Summary The uranyl(VI) malonate complex formation was studied by time-resolved laser-induced fluorescence spectroscopy (TRLFS) at pH 4 and an ionic strength of 0.1 M NaClO 4 . The uranium concentration was 5 × 10 −6 M at ligand concentrations from 1 × 10 −5 to 1 × −2 M. The measured fluorescence lifetimes of the 1:1 and 1:2 uranyl(VI) malonate complexes are 1.24 ± 0.02 µs and 6.48 ± 0.02 µs, respectively. The fluorescence lifetime of the uranyl(VI) ion is 1.57 ± 0.06 µs in 0.1 M perchloric media. The main fluorescence bands of the malonate complexes show a bathochromic shift compared to the uranyl(VI) ion and are centered at 494 nm, 515 nm and 540 nm for the 1:1 complexes and at 496 nm, 517 nm and 542 nm for the 1:2 complex. The spectra of the individual uranyl(VI) malonate complexes were calculated using a multi exponential fluorescence decay function for each intensity value at each wavelength, covering the entire wavelength range. Stability constants were determined for the complexes UO 2 C 3 H 2 O 4 ° (aq) and UO 2 (C 3 H 2 O 4 ) 2 2− from results of spectra deconvolution using a least square fit algorithm (logβ 1 ° = 4.48 ± 0.06, logβ 2 ° = 7.42 ± 0.06 or log K 2 ° = 2.94 ± 0.04). The results are compared with literature values obtained by potentiometric measurements.

On Use of Urea- and Phenol-Treated Skin Test Antigens for Diagnosis of Lymphogranuloma venereum. (1947)

Summary1. Saline suspensions prepared from yolk sacs heavily infected with the virus of Lymphogranuloma venereum and inactivated with 2% urea or 0.5% phenol constituted satisfactory diagnostic skin test antigens in high dilutions.2. Yolk sac suspensions treated with phenol so as to enhance their complement-fixing activity 16-fold were not appreciably more active as skin test antigens than urea-treated suspensions.
Clonal Accumulation of Activated CD8<sup>+</sup>T Cells in the Central Nervous System during the Early Phase of Neuroborreliosis (2003)

Borrelia burgdorferi may cause an acute infection of the central nervous system (CNS) that rarely leads to chronic disease. To characterize host immunity to B. burgdorferi in humans, we performed serial T cell receptor (TCR) variable beta (TCRBV) chain analyses in blood and cerebrospinal fluid (CSF) samples from 10 patients with acute neuroborreliosis. In most patients, we found significant differences in TCRBV expression between CSF and peripheral blood T cells, predominantly involving CD8(+) T cells. T cells that accumulated in the CSF had a memory phenotype and expressed high levels of C-C chemokine receptor 5 and CD69. Serial studies demonstrated that CD8(+) T cell accumulation decreased continuously after resolution of the infection. In 2 patients, serial analysis of the TCR-alpha and -beta chain sequences revealed that overexpression of TCRBV in CSF was caused by extensive clonal expansion of CD8(+) T cells. Our findings support the role of CD8(+) T cells during the early host defense against spirochete infection of the CNS.
C-band waveguide amplifier produced by femtosecond laser writing (2005)

An optical waveguide amplifier fabricated on erbium-ytterbium-doped phosphate glass by direct femtosecond laser writing is demonstrated. The waveguides are manufactured using 1040-nm radiation from a diode-pumped cavity-dumped Yb:KYW oscillator, operating at a 885 kHz repetition rate, with a 350 fs pulse duration. Peak internal gain of 9.2 dB is obtained at 1535 nm, with a minimum internal gain of 5.2 dB at 1565 nm. Relatively low insertion losses of 1.9 dB enable for the first time an appreciable net gain in the full C-band of optical communications.
Automatic verification of algebraic transformations (2004)

Programmers applying nontrivial code transformations are often faced with the problem of ensuring the functional equivalence of original and transformed programs. A pragmatic approach to the problem is to provide a tool to the programmers to check the equivalence of the two programs after applying the transformations. In prior work we have developed such a tool to handle important transformations like loop and sub-expression propagation. Here we report our progress on extending the tool to also handle algebraic transformations.
Interpreting competition experiments in host-guest chemistry (2009)

The quest for functional materials targeted for specific applications is ever increasing as societal needs and demands mount with advancing technology. One class of inorganic-organic hybrid materials, metal-organic materials (MOMs), has burgeoned in recent years due, in part, to effective design strategies (i.e. reticular chemistry) for their synthesis and their inherent [and readily interchangeable] hybrid, highly functional character. The molecular building block (MBB) approach introduces the ability to generate rigid and directional building blocks, mostly in situ, for the construction of MOMs having specific underlying networks and/or targeted functions/properties. Here we will discuss three basic strategies based on the MBB approach. Three classes of MBBs can be targeted and utilized in the assembly of functional MOMs: 1) single-metal-ion-based MBBs, which promote the rational construction, by forcing rigidity and directionality through control of the metal coordination sphere and judicious selection of suitable hetero-functional (N-, O-coordination) organic ligands, of porous MOMs with extra-large cavities, including zeolitelike metal-organic frameworks (ZMOFs); 1 2) multi-nuclear metal cluster-based MBBs, where, for example, simple metal-carboxylate clusters possess multiple metal-oxygen coordination bonds that result in the generation of rigid nodes with fixed geometry that, when combined with organic ligands of specific geometry, lead to the construction of desired MOMs (e.g. soc-MOFs); 2 and 3) supermolecular building blocks (SBBs), which involve enhanced built-in directional and structural information (e.g. high degree of symmetry and connectivity) compared to simple MBBs and allow the construction of high-connectivity nets (e.g. rht-MOFs). 3 The MBB approach and associated strategies, as well as physical properties of some corresponding MOMs (i.e. porosity, hydrogen sorption, catalysis, inclusion and sensing) will be discussed.
Preparation of SERS‐active substrates with large surface area for Raman spectral mapping and testing of their surface nanostructure (2008)

Abstract Surface‐enhanced Raman scattering (SERS) is a powerful technique of Raman signal detection of substances at a low concentration level. It allows observation of structural details of films with very small thicknesses. It is possible to achieve the enhancement of Raman signal of species located on the surface of properly prepared SERS‐active substrates of up to ca 10 6 . One of the main requirements for the substrate to be SERS‐active is the proper roughness of the surface. In this work different SERS‐active Au and Ag substrates suitable for spectral mapping were prepared using procedures which consisted of electrochemical deposition of metal layer and further roughening with oxidation–reduction cycles (ORC) treatment. The nanostructures of the metal surfaces were tested using atomic force microscopy (AFM). Monolayers formed both by covalent and noncovalent linkages to the metal surface were detected and Raman spectral maps were then measured. Roughening procedure of the substrates was optimized and its effect on the SERS enhancement was discussed. The relations among the surface nanostructure, optimal roughening, type of linkage of the analyte to the surface of the substrate and the Raman signal enhancement for the experimental conditions were studied.

Analysis of Transport in a Pressure-Driven Membrane Separation Process (1985)

The analysis of transport through a membrane in a pressure-driven membrane separation process need not include assumptions about the microstructure of the membrane. An analysis of transport is presented which interprets phenomenological relations in terms of the strengths of physicochemical interactions in the solute-solvent-membrane material system. No assumptions about the membrane microstructure are made. The results of this analysis are compared with the results of an analysis of transport through finely porous membranes.
Silicon Nitride Based Coatings Grown by Reactive Magnetron Sputtering (2018)

Silicon nitride and silicon nitride-based ceramics have several favorable material properties, such as high hardness and good wear resistance, which makes them important materials for the coating industry. This thesis focuses the synthesis of silicon nitride, silicon oxynitride, and silicon carbonitride thin films by reactive magnetron sputtering. The films were characterized based on their chemical composition, chemical bonding structure, and mechanical properties to link the growth conditions to the film properties. Silicon nitride films were synthesized by reactive high power impulse magnetron sputtering (HiPIMS) from a Si target in Ar/N 2 atmospheres, whereas silicon oxynitride films were grown by using nitrous oxide as the reactive gas. Silicon carbonitride was synthesized by two different methods. The first method was using acetylene (C 2 H 2 ) in addition to N 2 in a Si HiPIMS process and the other was co-sputtering of Si and C, using HiPIMS for Si and direct current magnetron sputtering (DCMS) for graphite targets in an Ar/N 2 atmosphere. Langmuir probe measurements were carried out for the silicon nitride and silicon oxynitride processes and positive ion mass spectrometry for the silicon nitride processes to gain further understanding on the plasma conditions during film growth. The target current and voltage waveforms of the reactive HiPIMS processes were evaluated.
Pacemaker implantation in small hospitals: complication rates comparable to larger centres (2011)

There are no generally accepted norms of complication rates in pacemaker surgery. However, we found no indications that our centres have a rate of complications that is unacceptably high.
The four-centre reaction I * 2 + F2 studied by laser-induced chemiluminescence in molecular beams (1977)

The four-centre reaction between electronically-excited I*2 and ground-state F2 has been studied under crossed-beam conditions by observing the resulting IF* chemiluminescence. The I2* is prepared in the v′= 43 level of the B3Π(0+u) state using the 514.5 nm line of the argon ion laser as an excitation source. The IF* emission is observed to the blue of the laser line and a spectroscopic analysis indicates that the IF* reaction product that is formed in the B3Π(0+) state has a non-Boltzmann vibrational distribution extending to the predissociation limit. For the I*2(B)+ F2(X) reaction, the energetics allow the formation of two IF product molecules, both of which may be electronically-excited, but do not allow the formation of IF*(B)+ I + F. Although the energetically-favourable ground state reaction I2(X)+ F2(X)→ IF(X)+ IF(X) appears not to take place, the reaction I*2(B)+ F2(X)→ IF*(B)+ IF(X or A) occurs with a reaction cross section estimated to be between 10–50 × 10–16 cm2. From the correlation of orbital symmetries (Woodward-Hoffmann rules), the four-centre reaction I2+ F2 as well as I*2+ F2 both appear to be formally forbidden. A discussion is presented suggesting possible ways in which this symmetry restriction for I*2+ F2 can be relaxed.
Significance of hydrogen breath tests in children with suspected carbohydrate malabsorption (2014)

Hydrogen breath tests can be helpful in the evaluation of children with gastrointestinal symptoms including functional intestinal disorders. If applied for a variety of carbohydrates but only where indicated, around two-third of all children have positive results. The therapeutic consequences are successfully relieving symptoms in the vast majority of patients.
DES Effect on Males (1978)

We have found defects in the urogenital tract of males exposed to diethylstilbestrol (DES) in utero, but the anomalies are different than those expected from the data of Henderson and co-workers (Pediatrics 58:505, October 1976). They reported an increased incidence of suspected urethral stenosis in boys exposed to DES. Their conclusion was drawn from the response of 225 DES-exposed males to a questionnaire. We have thoroughly examined 163 DES-exposed males and found a significantly increased incidence of oligospermia, hypotrophic testes, low ejaculate volumes, epididymal cysts, and microphallus.1
Comportement thermique de l’hydroxyapatite en présence de divers oxydes (1991)

La calcination à haute température (900-1200°C) d’un mélange d’hydroxy-apatite stoechiométrique et d’oxydes de divers éléments (SiO2, TiO2, LiO2) permet dans certains cas l’introduction d’un élément dans le réseau apatitique.
