Radiographic Views and Imaging of the Shoulder (2000)

Summary: Diagnostic imaging of the shoulder has advanced rapidly over the past several years. Sophisticated imaging modalities, such as computed tomography scans, bone scans, arthrograms, magnetic resonance imaging, and ultrasonograms, are available for evaluating shoulder problems. However, the first study of injuries and abnormal conditions about the shoulder is standard radiography. Shoulder radiographs provide essential information to the clinician, such as the presence of bony lesions and evidence of dislocation. Standard views and several special views are available to help the clinician make the diagnosis.

Growth Hormone Secretagogue Binding Sites in Peripheral Human Tissues1 (2000)

The family of GH secretagogues (GHS) includes peptidyl (hexarelin) and nonpeptidyl (MK 0677) molecules possessing specific receptors in the brain, pituitary, and thyroid. GHS receptor subtypes have also been identified in the heart; and a gastric-derived peptide, named ghrelin, has recently been proposed as a natural ligand. Our aim was to investigate the presence of GHS receptors in a wide range of human tissues, by radioreceptor assay with [125I]Tyr-Ala-hexarelin. GHS receptors were detected mainly in the myocardium, but they were also present (in order of decreasing binding activity) in adrenal, gonads, arteries, lung, liver, skeletal muscle, kidney, pituitary, thyroid, adipose tissue, veins, uterus, skin, and lymphnode. In contrast, negligible binding was found in parathyroid, pancreas, placenta, mammary gland, prostate, salivary gland, stomach, colon, and spleen. Hexarelin, MK 0677, and human ghrelin completely displaced the radioligand from binding sites of endocrine tissues, but MK 0677 and ghrelin were less potent than hexarelin. In nonendocrine tissues, both MK 0677 and ghrelin were inactive in displacement of [125I]Tyr-Ala-hexarelin, whereas hexarelin was as active as a displacing agent in endocrine tissues. This study provides the first detailed analysis of the tissue localization of GHS receptors and suggests that a still unknown receptor subtype, specific for peptidyl GHS, may exist in the heart and in other tissues.
On-Line Visual Tracking with Occlusion Handling (2020)

One of the core challenges in visual multi-target tracking is occlusion. This is especially important in applications such as video surveillance and sports analytics. While offline batch processing algorithms can utilise future measurements to handle occlusion effectively, online algorithms have to rely on current and past measurements only. As such, it is markedly more challenging to handle occlusion in online applications. To address this problem, we propagate information over time in a way that it generates a sense of déjà vu when similar visual and motion features are observed. To achieve this, we extend the Generalized Labeled Multi-Bernoulli (GLMB) filter, originally designed for tracking point-sized targets, to be used in visual multi-target tracking. The proposed algorithm includes a novel false alarm detection/removal and label recovery methods capable of reliably recovering tracks that are even lost for a substantial period of time. We compare the performance of the proposed method with the state-of-the-art methods in challenging datasets using standard visual tracking metrics. Our comparisons show that the proposed method performs favourably compared to the state-of-the-art methods, particularly in terms of ID switches and fragmentation metrics which signifies occlusion.

A new methodology for atrial flutter ablation by direct visualization of cavotricuspid conduction with voltage gradient mapping: a comparison to standard techniques (2013)

(i) Voltage gradient mapping visualized regions of critical CTI conduction, (ii) ablation of LVB terminated AFL and resulted in BDB, (iii) repeat mapping confirmed the absence of trans-isthmus voltage, and (iv) Compared with standard ablation, voltage gradient mapping decreases total RF lesions, lesions to AFL termination, and total RF time. Use of voltage gradient mapping can facilitate successful AFL ablation.
Response of four wheat cultivars to applications of (2-chloroethyl)trimethylammonium chloride (CCC) (1972)

The effect of CCC on the grain yield of two Australian and two Mexican semi-dwarf cultivars, with two seeding rates, and two levels of N fertilizer, was studied in the held. Grain yield increases, particularly in CV. Timgalen, were produced by CCC through the control of lodging, an increase in the number of grains per ear and an increase in the number of ears per unit area. Even where only a small effect on height was produced in CV. Pitic 62, the grain yield was increased as a result of more ear-bearing tillers. No significant grain yield increases were found in R.K.F. The delay in ear emergence in some cultivars as a result of CCC did not change the number of florets formed but it may have improved floral fertility as indicated by the higher number of grains per ear at harvest. The differential response of the cultivars to CCC is demonstrated by the plant height data. In decreasing order of height reduction they were Robin, Timgalen, Pitic 62 and R.K.F.
Cytotoxic Lignans of Justicia ciliata (1999)

Two new naturally occurring 1-aryl-2,3-naphthalide lignans, cilinaphthalide A (1) and cilinaphthalide B (2), and nine known compounds were isolated from the whole plant of Justicia ciliata. Their structures were established by spectral analysis, and their cytotoxic activity was evaluated against several different cell lines. The known compound, justicidin A, showed potent cytotoxic effects against T-24, CaSki, SiHa, HT-3, PLC/PRF/5, and 212 cells in vitro.
Conversation Analysis of Multi-Party Conferencing and Its Relation to Perceived Quality (2011)

This paper investigates interactivity in multi-party conferencing. To this aim the state model often used to descibe two-party telephone conversations is redefined for more than two interlocutors. We adapt and apply statistical measures such as conversation state probabilities to recordings made during a three-party conferencing quality test, which was designed to evaluate the perceived quality under various speech transmission properties. In a second step, we associate the different observed degrees of interactivity to the quality test ratings. Results give a first insight into the co-dependence of transmission properties, the interlocutors' communication behavior and their integral quality judgment.
Enzymatic Nanolithography of a Self-Assembled Oligonucleotide Monolayer on Gold (2004)

This paper describes a simple strategy to biochemically manipulate a surface at the nanoscale by enzyme dip-pen nanolithography using an endonuclease (DNase I) that is directly patterned on a self-assembled monolayer presenting a terminal oligonucleotide. Physisorbed nanopatterns of DNase I carried out nanoscale enzymology at the surface creating oligonucleotide patterns with the fidelity of the patterned enzyme because of the affinity of the enzyme for the immobilized, oligonucleotide substrate.
Monte-Carlo Modeling of Photoelectron Kinetics in Quantum-Dot Photodetectors (2009)

Using Monte-Carlo method, we simulate kinetics and transport of electrons in different types of InAs/GaAs quantum-dot infrared photodetectors. Our simulation program exploits Γ-L-X model of the conduction band of semiconductor and it includes three major types of electron scattering on: 1) acoustic phonons, 2) polar optical phonons, and 3) intervalley phonons. The results of simulation demonstrate that the combination of local potential barriers around quantum dots and quantum-dot structure with collective barriers can be used to achieve long carrier lifetimes, and therefore high photoconductive gain, responsivity, and detectivity.
How common is the most common adult movement disorder? Estimates of the prevalence of essential tremor throughout the world (1998)

Essential tremor (ET) is the most common adult movement disorder, as much as 20 times more prevalent than Parkinson's disease. Estimates of the crude prevalence of ET range widely from 0.08 to 220 cases per 1000 persons, a 2750-fold difference. There has been no formal attempt to synthesize these disparate results. Our purpose is to provide an overview of existing studies, to examine methodologic issues that may account for this tremendous variability in results, and to provide a more precise estimate of the prevalence of ET. Nineteen studies of the prevalence of ET were reviewed. Factors that contribute to the broad range of prevalence estimates include (a) differences in study design that influence validity and (b) differences in characteristics of study populations that influence comparability of studies. If we limit our examination to studies that (a) provided diagnostic criteria for ET, (b) defined ET as an action tremor, and (c) used community-based rather than service-based designs, then five studies remain, and the prevalence of ET is 4.1 to 39.2 cases per 1000, a 9.6-fold difference. Four of these five provided age-stratified data. Among these four, the prevalence of ET in those over the age of 60 years was 13.0 to 50.5 cases per 1000, a 3.9-fold difference.
Strong activation of MgCl2‐supported Ziegler‐Natta catalysts by treatments with BCl3: Evidence and application of the “cluster” model of active sites (2009)

Abstract Heterogeneous Ziegler‐Natta precatalysts (with phthalate as internal donor) were modified by treatments with BCl 3 (2 h in heptane; T = 20–90 °C; B/Ti = 0.1–5) before their use in the polymerization of propylene to modify the active sites distribution. If performed on previously “detitanated” precatalysts, the treatment leads to a strong increase of productivity (up to one order of magnitude) without drastic modifications of polypropylenes properties (tacticity, molecular weight distribution). In addition, these findings are in good agreement with the hypothesis of a “cluster” organization of active sites allowing to rationalize activation by BCl 3 by formation of heteronuclear B‐Ti clusters. The activation method was also applied to unmodified precatalysts and gave a significant gain of productivity. The simple and versatile activation process can also be performed under mild conditions (low T and low [BCl 3 ]). © 2009 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 47: 5784–5791, 2009

Angular selective window coatings: theory and experiments (1997)

This review is devoted to the angular selectivity that can be obtained in thin films prepared under conditions such that they contain inclined absorbing regions of sizes much smaller than the wavelength of visible light. The films are of considerable interest as window coatings for energy-conscious architecture and, potentially, in the automotive sector. The theoretical basis for modelling the optical properties is presented, comprising rigorous bounds on the dielectric function, effective medium theories pertinent to different microgeometries and equations for treating the optics of anisotropic thin films. Experimental data are reported for films made by oblique-angle evaporation of Cr and for reactive and non-reactive oblique-angle sputtering of Cr, Al, Ti and W. The highest angular selectivity was obtained with evaporated Cr, whereas the highest luminous transmittance, combined with some angular selectivity, was found with reactively sputtered Al. Films made from Ti showed angular selectivity mainly in the infrared, whereas films made from W could display angular selective electrochromism. Samples of several types were subjected to elaborate theoretical analysis using effective-medium theories and it was seen that theory and experiment could be reconciled using plausible parameters to specify the microstructures of the films. Thus it appears that the angular, spectral and polarization dependences of obliquely deposited films can be understood, at least approximately, in terms of conceptually simple theoretical models.
Recovery of acetic acid from dilute acetate solution (1982)

Cells sense physical properties of their environment including substratum rigidity, roughness, and topography of recognition sites. The cell surface displays continuous deformations of nanometer-scale amplitude and Hz frequency. Recent results support the hypothesis that these surface undulations constitute a powerful strategy for the rapid acquisition of environmental cues: transient contact with surroundings generates forces of piconewton intensity as a result of rapid formation and dissociation of intermolecular bonds. The combination of binding and steric forces is expected to drive conformational changes and lateral reorganization of membrane biomolecules, thus generating signaling cascades. We propose that spontaneous membrane mobility shapes the initial information generated by cell-to-surface contacts, and thereby biases later consequences of these interactions.
Comparison Between Liquid and Paste Karl Fischer Extractions for NIRS Water Calibrations (1989)

Abstract The acceptance of near infrared reflectance spectroscopy (NIRS) for the routine analysis of water in forage was made possible by the application of Karl Fischer (KF) water analysis as the primary reference method during calibration. Water is extracted by ball milling the sample in the presence of methanol (1:50), and an aliquot of the liquid phase is sampled and titrated. An alternative extraction utilizes a 20 g sample with 20 mL methanol, and an aliquot of the paste is sampled and titrated. The objectives of this study were to compare extraction procedures (i.e., liquid vs paste) on the determination of water in 75 milled grains and concentrate rations, and to develop and compare NIRS calibrations for water on the basis of both extraction methods. The majority of the samples (N = 61) had a 1.05 percentage unit greater water content (P &amp;lt; 0.05) from the paste method than from the liquid method. Bias between the extraction procedures was positively correlated (r2 = 0.84) to starch content. The lowered extraction efficiency of the liquid method is explained by its inability to account for water bound to starch. NIRS calibration and equation validation statistics were superior with water data from the paste method. The increased calibration errors with the liquid method also appear to reflect the inability of the method to accurately measure the total water concentration of the samples in relation to the water measurement based on the NIRS signals. The study concludes that the KF paste method is a superior primary reference method for the determination of water in flour obtained from cereal grains and concentrate rations.
Elderly Asian Patients Have Lower Revascularisation Rates and Poorer Outcomes for ST-Elevation Myocardial Infarction Compared to Younger Patients (2020)

Elderly patients with STEMI have poorer outcomes than MAO and young patients. This is potentially attributable to a myriad of factors including age, higher burden of comorbidities and a lesser likelihood of receiving revascularisation and guideline-recommended medical therapy.

Autothermal reforming of natural gas to synthesis gas:reference: KBR paper #2031. (2007)

This Project Final Report serves to document the project structure and technical results achieved during the 3-year project titled Advanced Autothermal Reformer for US Dept of Energy Office of Industrial Technology. The project was initiated in December 2001 and was completed March 2005. It was a joint effort between Sandia National Laboratories (Livermore, CA), Kellogg Brown & Root LLC (KBR) (Houston, TX) and Sued-Chemie (Louisville, KY). The purpose of the project was to develop an experimental capability that could be used to examine the propensity for soot production in an Autothermal Reformer (ATR) during the production of hydrogen-carbon monoxide synthesis gas intended for Gas-to-Liquids (GTL) applications including ammonia, methanol, and higher hydrocarbons. The project consisted of an initial phase that was focused on developing a laboratory-scale ATR capable of reproducing conditions very similar to a plant scale unit. Due to budget constraints this effort was stopped at the advanced design stages, yielding a careful and detailed design for such a system including ATR vessel design, design of ancillary feed and let down units as well as a PI&D for laboratory installation. The experimental effort was then focused on a series of measurements to evaluate rich, high-pressure burner behavior at pressures as high as 500 psi. The soot formation measurements were based on laser attenuation at a view port downstream of the burner. The results of these experiments and accompanying calculations show that soot formation is primarily dependent on oxidation stoichiometry. However, steam to carbon ratio was found to impact soot production as well as burner stability. The data also showed that raising the operating pressure while holding mass flow rates constant results in considerable soot formation at desirable feed ratios. Elementary reaction modeling designed to illuminate the role of CO{sub 2} in the burner feed showed that the conditions in the burner allow for the direct participation of CO{sub 2} in the oxidation chemistry.

Correlation of Total Uterine Activity to Blood Loss in the Third Stage of Labour (1996)

In 27 women, uterine activity in the third stage of labour was correlated with blood loss measured quantitatively during the same period of time. Myometrial activity was reflected by total intrauterine pressures measured using a Gaeltec catheter tipped pressure transducer inserted transcervically within 5 min of delivery of the placenta. Blood loss over the same 2-hour period was collected on absorbent paper and measured in the laboratory by colorimetric measurement of the haemoglobin content. As total uterine activity in the third stage of labour decreases total blood loss increases, but there is a poor correlation of uterine activity to total blood loss over the same period of time, probably because of biological variations in myometrial activity in normal women.
Treatment of Lower Eyelid Retraction by Expansion of the Lower Eyelid With Hyaluronic Acid Gel (2007)

Based on our preliminary results, hyaluronic acid gel shows promise as a treatment modality for the management of lower eyelid retraction. Long-term follow-up will better clarify the required frequency of maintenance injections, the degree of hyaluronic acid gel retention, and the position of the lower eyelid over time.
