Twin-to-Twin Transfusion Syndrome (2008)

Most anomalies seen in fetuses and neonates who have chronic twin-to-twin transfusion syndrome (TTTS) represent sequelae of cardiovascular dysfunction or vascular disruption. The placental examination can provide critical information to the neonatologist caring for infants who have a history of TTTS, especially in instances wherein the twins are not necessarily growth-discordant but have cardiovascular or renal dysfunction or neuropathologic findings. In this review, we present an updated discussion of the fetal and neonatal pathologies and adverse sequelae associated with TTTS and advances in antenatal diagnosis and clinical interventions for monochorionic gestations complicated by TTTS. We also present highlights of the placental examination so the neonatologist can inspect the placenta at the time of delivery and possibly gain insights that may affect patient care.

Muscle chemoreflex alters vascular conductance in nonischemic exercising skeletal muscle (1994)

Previous studies have shown that the muscle chemoreflex causes an augmented blood pressure response to exercise and partially restores blood flow to ischemic muscle. The purpose of this study was to investigate the effects of the muscle chemoreflex on blood flow to nonischemic exercising skeletal muscle. During each experiment, dogs ran at 10 kph for 8-16 min and the muscle chemoreflex was evoked by reducing hindlimb blood flow at 4-min intervals (0-80%). Arterial blood pressure, hindlimb blood flow, forelimb blood flow, and forelimb vascular conductance were averaged over the last minute at each level of occlusion. Stimulation of the muscle chemoreflex caused increases in arterial blood pressure and forelimb blood flow and decreases in forelimb vascular conductance. The decrease in forelimb vascular conductance demonstrates that the muscle chemoreflex causes vasoconstriction in the nonischemic exercising forelimb. Despite the decrease in vascular conductance, the increased driving pressure caused by the pressor response was large enough to produce an increased forelimb blood flow.
Heat Conductivity in Polyatomic or Electronically Excited Gases. II (1957)

The usual Eucken equation for the heat conductivity of a molecule with internal degrees of freedom is derived and improved. In the improved form the correction to the coefficient of thermal conductivity for the internal degrees of freedom of the molecule is given by the factor 0.115+0.354 Cp/R. With the help of Part I, we prove that this approximation is valid only if the electronic states are not metastable and if the coefficients of diffusion of all the molecular quantum states are equal. The metastable electronic species should lead to anomalously large coefficients of thermal conductivity, whereas the usual excited electronic states, because of their gigantic size, should give a much smaller contribution to the coefficient of thermal conductivity than would be expected on the basis of the Eucken assumption.
The Impact of Manager Output Control on Employee`s Satisfaction with Managers (2003)

This study was to investigate the relationship between food ＆ beverage employees` perceived controls and satisfaction with manager by gender and type of employment. Data were collected from 220 employees in the context of a hotel food ＆ beverage department. The data were analyzed using multiple regression. Chow test, and testing for parallelism. The findings can be summarized as follows: First, output reward and output information have significant positive influence on satisfaction with manager, but output punishment have significant negative influence on satisfaction with manager. Second, output reward is related to satisfaction with manager in the case of female employees, with output reward and output information are related to satisfaction with manager in the case of male employees. Third, output reward is related to satisfaction manager in the case of one year contractors, while output reward and output information are related to satisfaction with manager in case of full timers. In addition, summary and implications, limitations of this study, and future research directions are discussed.
Effects of Deletion of the Carboxyl-terminal Domain of ApoA-I or of Its Substitution with Helices of ApoA-II on in Vitro and in Vivo Lipoprotein Association (1996)

In the present study, the lipoprotein association of apoA-I, an apoA-I (DeltaAla190-Gln243) deletion mutant and an apoA-I (Asp1-Leu189)/apoA-II (Ser12-Gln77) chimera were compared. At equilibrium, 80% of the 125I-labeled apolipoproteins associated with lipoproteins in rabbit or human plasma but with very different distribution profiles. High density lipoprotein (HDL)2,3-associated fractions were 0.60 for apoA-I, 0.30 for the chimera, and 0.15 for the deletion mutant, and corresponding very high density lipoprotein-associated fractions were 0.20, 0.50, and 0.65. Clearance curves after intravenous bolus injection of 125I-labeled apolipoproteins (3 microg/kg) in normolipemic rabbits could be adequately fitted with a sum of three exponential terms, yielding overall plasma clearance rates of 0.028 +/- 0.0012 ml.min-1 for apoA-I (mean +/- S.E.; n = 6), 0.10 +/- 0.008 ml.min-1 for the chimera (p < 0.001 versus apoA-I) and 0.38 +/- 0.022 ml.min-1 for the deletion mutant (p < 0.001 versus apoA-I and versus the chimera). Fractions that were initially cleared with a t1/2 of 3 min, most probably representing free apolipoproteins, were 0.30 +/- 0.04, 0.50 +/- 0.06 (p = 0.02 versus apoA-I), and 0.64 +/- 0.07 (p = 0.002 versus apoA-I), respectively. At 20 min after the bolus, the fractions of injected material associated with HDL2,3 were 0.55 +/- 0.06, 0.25 +/- 0.03 (p = 0.001 versus apoA-I), and 0.09 +/- 0.01 (p < 0.001 versus apoA-I and versus the chimera), respectively, whereas the fractions associated with very high density lipoprotein were 0. 15 +/- 0.006, 0.25 +/- 0.03 (p = 0.008 versus apoA-I), and 0.27 +/- 0.03 (p = 0.003 versus apoA-I), respectively. The ability of the different apolipoproteins to bind to HDL3 particles and displace apoA-I in vitro were compared. The molar ratios at which 50% of 125I-labeled apoA-I was displaced from the surface of HDL3 particles were 1:1 for apoA-I, 3:1 for the chimera and 12:1 for the deletion mutant, indicating 3- and 12-fold reductions of the affinities for HDL3 of the chimera and the deletion mutant, respectively. These data suggest that the carboxyl-terminal pair of helices of apoA-I are involved in the initial rapid binding of apoA-I to the lipid surface of HDL. Although the lipid affinity of apoA-II is higher than that of apoA-I, substitution of the carboxyl-terminal helices of apoA-I with those of apoA-II only partially restores its lipoprotein association. Thus, this substitution may affect cooperative interactions with the middle amphipathic helices of apoA-I that are critical for its specific distribution over the different HDL species.
<title>Triple FOV IR sensor: an optimum configuration geometry</title> (1996)

Dual field of view sensors form the basis of many current IR systems. Emerging scenarios, however, are beginning to call for a wide range of field coverage, and are stretching the capabilities of dual field systems beyond the point where a comfortable balance of fields is obtainable. Provision of a 3rd field of view opens up an extended range of operational possibilities, and in many scenarios offers a sufficient level of functional availability when weighted against the cost of additional on-board FLIRs. The design evolution of a lightweight and compact triple field optical system is described. The system features a novel, optimum geometry carousel, which enables provision of 3 fields with a single mechanism. The design is modular and flexible, offering ratios up to 20:1 between the widest and narrowest field. Hybrid optical element assist in achieving performance with minimum element count, and a variant of the design featuring special materials (GaAs/KRS5) offers extended temperature capability and athermalization for specific applications. Configuration constraints are defined, limitations of alternative approaches explored, and characteristics of the preferred design are presented. Opto-mechanical design features are described which take advantage of the novel FOV change concept to produce a stable, balanced system which can offer advantages compared with a zoom in the operational environment. The modular nature of the configuration, which permits field of view and scanner interfacing to be readily tailored to suit any specific application while retaining commonality of main structural components and mechanisms, is also illustrated.
An Efficient Certificateless Encryption for Secure Data Sharing in Public Clouds (2013)

We propose a mediated certificateless encryption scheme without pairing operations for securely sharing sensitive information in public clouds. Mediated certificateless public key encryption (mCL-PKE) solves the key escrow problem in identity based encryption and certificate revocation problem in public key cryptography. However, existing mCL-PKE schemes are either inefficient because of the use of expensive pairing operations or vulnerable against partial decryption attacks. In order to address the performance and security issues, in this paper, we first propose a mCL-PKE scheme without using pairing operations. We apply our mCL-PKE scheme to construct a practical solution to the problem of sharing sensitive information in public clouds. The cloud is employed as a secure storage as well as a key generation center. In our system, the data owner encrypts the sensitive data using the cloud generated users’ public keys based on its access control policies and uploads the encrypted data to the cloud. Upon successful authorization, the cloud partially decrypts the encrypted data for the users. The users subsequently fully decrypt the partially decrypted data using their private keys. The confidentiality of the content and the keys is preserved with respect to the cloud, because the cloud cannot fully decrypt the information. We also propose an extension to the above approach to improve the efficiency of encryption at the data owner. We implement our mCL-PKE scheme and the overall cloud based system, and evaluate its security and performance. Our results show that our schemes are efficient and practical.
Parley as an approach to distributed detection (1995)

Decentralized detection networks implement local likelihood ratio tests at each sensor and combine the local decisions into a global decision. In general this is a "one-pass" procedure, with data transmission from the sensors (or subordinate decision makers) to the fusion center. There have been treatments of multipass schemes, but usually the approach has been to update the local decisions based on the previous fused decision. We explore the use of feedback (of all sensor decisions to all sensors) and successive retesting and rebroadcasting of the updated decisions until a common decision or consensus is reached, an operation we call parley due to its similarity to the process of discussion and negotiation by a team of human decision makers. We consider two modes of operation of such a network. In the first, all sensors are as correct as possible at all times. We see that this network is fast in reaching consensus, but not particularly as "correct" as it could be. Under the second scheme, we observe that via feedback it is possible for the network to make an optimum decision-this may, of course, require several rounds of parley. Of particular interest is that under both schemes a consensus always occurs-the sensors never "agree to disagree".< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
ISOLATION AND STRUCTURAL ANALYSIS OF NEW FRUCTANS PRODUCED BY CHICORY (2001)

This report describes a new series of oligosaccharides, which is formed in chicory roots under forcing conditions and during in vitro experiments using purified chicory 1-FFT (fructan:fructan 1-fructosyl transferase). It was demonstrated that the three smallest members of this new series (disaccharide, trisaccharide and tetrasaccharide) contain exclusively β-D-fructosyl residues after hydrolysis. The present data demonstrate that the smallest compound is levanbiose and that the other oligomers of this new series of fructans do not belong to the linear 2→6 linked levan-oligosaccharides nor to the linear 2→1 linked inulo-oligosaccharides. A combination of several chromatographic techniques yielded a fraction that contained only the compound with degree of polymerisation (DP) 2 (levanbiose, β-D-fructofuranosyl-(2→6)-D-fructofuranose), and a mixture of DP 3 of the new series and 1-kestose. Using homonuclear and heteronuclear 2D NMR experiments the complete 1H and 13C NMR assignments of levanbiose and DP 3 were obtained. From High Performance Anion Exchange Chromatography (HPAEC) and NMR experiments of DP 3 of the new series it was concluded that the molecule contains a β-D-fructofuranosyl residue 2→1 linked to the non-reducing moiety of levanbiose, and thus has to be named β-D-fructofuranosyl-(2→1)-β-D-fructofuranosyl-(2→6)-D-fructofuranose. The simple and regular pattern of the HPAEC retention times of the new oligosaccharides suggests that it is a homologous series of oligomers build by 2→1 elongation with β-D-fructofuranosyl residues at the non-reducing residue of levanbiose.
An anamorphic imaging model to correct geometric distortion in planar holographic stereograms (1989)

This thesis demonstrates the importance of an accurate imaging model for making holographic stereograms by evaluating the geometric perspective distortion that is seen in flat holographic stereograms made using a circularly symmetric imaging model. A correct anamorphic imaging model for flat holographic stereograms is discussed and the limitations of the new model are explored. An implementation of the anamorphic imaging model as a computer system for creating geometric distortion-free holographic stereograms IS described. Holographic stereograms were made using the computer system. A comparison is made of the uncorrected and corrected holographic stereograms. From viewing these holographic stereograms it is apparent that geometric distortion can be eliminated by using the correct anamorphic imaging model when creating holographic stereograms.
Endoscopic mucosal resection for Barrett’s esophagus-related neoplasia (2007)

Evaluation of: Lopes CV, Hela M, Pesenti C et al. Circumferential endoscopic resection of Barrett’s esophagus with high-grade dysplasia or early adenocarcinoma. Surg. Endosc. 21(5), 820–824 (2007).High-grade dysplasia may progress to esophageal adenocarcinoma in 16–32% of patients. Esophagectomy is the definitive therapy; however, the procedure has a mortality rate of 3–12% and 29–56% of patients develop at least one serious postoperative complication. Endoscopic mucosal resection (EMR) for high-grade dysplasia or early carcinoma has been proposed for selected patients. With conventional EMR, Barrett’s epithelium is left behind, invasive lesions may be missed due to sampling error and long-term outcomes remain unknown. A recent study reports a mean follow-up of 31.6 months in patients treated with circumferential EMR. Allowing multiple sessions of EMR and repeat EMR for recurrence, the study reports a 90% success rate. EMR changed the initial biopsy diagnosis in 34% of patients. Another trial of EMR recently described the long-term follow-up of patients with early Barrett’s-associated cancer who were managed with EMR. Complete local remission was achieved in 99% of patients. The 5-year survival rate was 98%. EMR should be a part of the evaluation of Barrett’s-associated neoplasia. As mucosal resection evolves, the technique may become standard management for highly selected subgroups of patients.

Hydroxy-substituted Cobalt Tetraphenylporphyrins as Electrocatalysts for the Reduction of <font>O</font><sub>2</sub> (1997)

The possible effects of the electron-donating properties of p-hydroxyphenyl groups on the catalytic activity of cobalt porphyrins toward the electro-reduction of O 2 were explored with three cobalt porphyrins having p-hydroxyphenyl substituents in the meso position of the porphyrin ring. The porphyrins were examined as electrocatalysts adsorbed on the surfaces of pyrolytic graphite electrodes in aqueous solution and as homogeneous catalysts dissolved in methanolic solutions. The adsorbed molecules exhibited a higher catalytic activity than those in solution and accomplished the reduction of a portion of the O 2 molecules reaching the electrode to H 2 O . However, the four-electron reduction was indirect, with H 2 O 2 being formed as an intermediate that was subsequently reduced. Although the introduction of the electron-donating p-hydroxyphenyl substituents on the porphyrin ring altered the catalytic activity of the cobalt porphyrins, the effect was not as great as can be obtained by coordinating ruthenium (II) complexes to π-accepting ligands in the meso position of the porphyrin ring.

An interactive multimedia framework for digital heritage narratives (2010)

The cultural heritage of a region is conveyed by both tangible physical artifacts and intangible aspects in the form of stories, dance styles, rituals, etc. Hitherto, the task of creating digital representations for each of these aspects has been addressed in isolation, i.e. using specific media most suited to the artifact such as video, audio, three-dimensional (3D) models, scanning, etc. The challenge of bringing together these separate elements to create a coherent story, however, has remained unaddressed until recently. In this paper we present a unified digital framework that enables the integration of disparate representations of heritage elements into a holistic entity. Our approach results in a compelling and engaging narration that affords a unified user experience. Our solution supports both active (user-controlled explorations) and passive (watching pre-orchestrated narrations) user interactions.

Determination of Withanolides in Withania somnifera by Liquid Chromatography: Single-Laboratory Validation, First Action 2015.17 (2016)

An LC method was developed and validated in 2007 for analyzing Withania somnifera raw material (root) and dried extracts for withanolide content, including withanoside IV, withanoside V, withaferin A, 12-deoxywithastromonolide, withanolide A, and withanolide B. The method involved the extraction of the analytes with methanol, their subsequent filtration, and then analysis on a C18 column with an acetonitrile gradient and UV detection. Single-laboratory validation yielded linearity generally in the range of 20 to 200 μg/mL for each analyte, with a repeatability precision of RSD < 3% in most cases, and recovery in the range of 90 to 105%. These results compare well with the performance criteria recently detailed in AOAC Standard Method Performance Requirement 2015.007. The method was shown to be rugged with respect to different analysts, equipment, and days of analysis, and the sample solution was shown to be stable for 24 h at room temperature after extraction. The method was reviewed by the AOAC Expert Review Panel on Dietary Supplements (Set 2 Ingredients) and approved for First Action Official MethodSM status.
Clinical Studies of Styrene Workers: Initial Findings (1976)

Styrene monomer is a high volume chemical used chiefly in production of polystyrene. A clinical survey of 493 production workers was undertaken at the oldest and largest monomer production, polymerization, and extrusion facility in the U.S. Relative exposure durations and levels were obtained from occupational histories. Significant differences between the high and low exposure groups were found with regard to history of acute prenarcotic symptoms, acute lower respiratory symptoms, prevalence of FEV 1/FV less than 75 per cent, and elevated GCTP. Other liver function tests, chest x-ray, FVC less than 80 per cent, and hematological parameters showed no distinct pattern. A concomitant mortality study has been mounted and is in progress.
Stratified Assemblies of Magnetite Nanoparticles and Montmorillonite Prepared by the Layer-by-Layer Assembly (2000)

Hybrid thin films are prepared from 8 to 10 nm Fe3O4 nanoparticles and exfoliated montmorillonite clay by using layer-by-layer assembly on poly(diallyldimethylammonium bromide), PDDA. Distinct stratification of the Fe3O4/PDDA/clay films is obtained due to the sheetlike structure of the clay particles. This feature distinguishes these assemblies from their polyelectrolyte−polyelectrolyte analogues, where the layers of individual polyelectrolytes are strongly interdigitated. Being adsorbed on PDDA strictly parallel to the substrate surface, montmorillonite produces a dense layer of overlapping alumosilicate sheets, which virtually flawlessly separates one magnetite layer from another. The difference in magnetic properties between assemblies of various architectures is attributed to the insulation effect of clay layers inserted between magnetic layers. The montmorillonite sheets disrupt the electron exchange interactions between the magnetite nanoparticles in adjacent layers, thereby limiting the magnetization reversal to two dimensions. Some optical properties of Fe3O4/PDDA films are investigated as well. When they are deposited on thin plastic substrate, oscillations of optical density were observed in the red part of the UV−vis spectrum. This effect, which was never been observed for conventional, thick substrates such as glass slides, stems from the interference of the light beams passed through and reflected off of the assembled film.
