Prevention of Central Venous Catheter-Related Infections by Using Maximal Sterile Barrier Precautions during Insertion (1994)

Maximal sterile barrier precautions during the insertion of nontunneled catheters reduce the risk of catheter infection. This practice is cost-effective and is consistent with the practice of universal precautions during an invasive procedure.
Pressure evolution of electrical transport in the 3D topological insulator (Bi, Sb)2(Se, Te)3 (2014)

The group V-VI compounds—like Bi2Se3, Sb2Te3, or Bi2Te3—have been widely studied in recent years for their bulk topological properties. The high-Z members of this series form with the same crystal structure, and are therefore amenable to isostructural substitution studies. It is possible to tune the Bi-Sb and Te-Se ratios such that the material exhibits insulating behavior, thus providing an excellent platform for understanding how a topological insulator evolves with applied pressure. We report our observations of the pressure-dependent electrical transport and crystal structure of a pseudobinary (Bi,Sb)2(Te,Se)3 compound. Similar to some of its sister compounds, the (Bi,Sb)2(Te,Se)3 pseudobinary compound undergoes multiple, pressure-induced phase transformations that result in metallization, the onset of a close-packed crystal structure, and the development of distinct superconducting phases.
Chemische Informations‐systeme der Natur: Insektenpheromone (1993)

Abstract Pheromone sind Signale chemischer Informationssysteme der Natur. Als flüchtige Riechstoffe lösen sie vor allem bei Insekten Verhaltensänderungen aus: Sie dienen der Geschlechtsfindung, der Partnerwahl und Fortpflanzung, der Beuteaufspürung, der Markierung von Futter‐ und Nestplätzen sowie der Regulation des Sozial‐ und Kastenwesens. Solche Eigenschaften werden heute bei der Bekämpfung von Schadinsekten ausgenutzt.
Hypopigmented Mycosis Fungoides Associated With Human T Cell Lymphotropic Virus Type I Tax in a Pediatric Patient (1999)

* Abbreviations:
 MF = : mycosis fungoides • HTLV-I = : human T cell lymphotropic virus type I • NYUMC = : New York University Medical Center • UVB = : ultraviolet B • PBMC = : peripheral blood mononuclear cells • PCR = : polymerase chain reaction

The cutaneous T cell lymphoma, mycosis fungoides (MF), is characterized by proliferation of atypical lymphocytes that preferentially home to the skin. Usually, afflicted patients are middle-aged and present with erythematous patches and plaques. Although often indolent, the disease may progress to a tumor stage and involve viscera. The present report concerns a 7-year-old black boy, who was born in Grenada and who presented with a 3-year history of slowly developing, hypopigmented patches scattered over his buttocks, legs, and arms involving approximately 20% of his body surface. He was serologically negative for antibodies to human T cell lymphotropic virus types I/II (HTLV-I/II). The young age of this patient, the hypopigmentation of his lesions, his origin from a region of the world where HTLV-I is endemic, and our previous studies showing an association of HTLV-I tax with MF,1 ,2 prompted us to investigate whether the patient and/or his first-degree relatives were infected with this virus. While the patient's healthy mother proved to be a carrier of HTLV-I, with antibodies to the virus when tested by routine serologic methods, the patient, like other patients with MF, as well as his healthy younger brother, harbored only deleted HTLV-I proviral sequences. The possible implications of this observation are discussed.

A 7-year-old black boy, born in Grenada, was referred to the Dermatology Service at New York University Medical Center (NYUMC) because of a 3-year history of hypopigmented macules and patches covering about 20% of his body (Fig 1). The hypopigmented lesions were not pruritic, scaly, or palpable to touch. He was otherwise well. His past medical history was relevant only in that he was born by spontaneous vaginal delivery and that he had been breastfed. Physical examination revealed no lymphadenopathy or organomegaly. Routine blood counts and biochemistries were all within normal range. He was serologically …
Biological significance of endogenous methylarginines that inhibit nitric oxide synthases (1999)

The guanidino-methylated arginine analogue NG monomethyl-L-arginine (L-NMMA) has been the standard nitric oxide synthase inhibitor used to evaluate the role of the L-arginine:nitric oxide pathway. However, L-NMMA and other methylated arginine residues are also synthesised in vivo by the action of a family of enzymes known as protein arginine methyltransferases. Proteolysis of proteins containing methylated arginine residues releases free methylarginine residues into the cytosol from where they may pass out of the cell into plasma. Of the three known methylarginine residues produced in mammals only asymmetrically methylated forms (L-NMMA and asymmetric dimethylarginine (ADMA)) but not symmetrically methylated arginine (symmetric dimethylarginine (SDMA)) inhibit nitric oxide synthase (NOS). We and others have proposed that endogenously produced asymmetrically methylated arginines may modulate NO production and that the accumulation of these residues in disease states may contribute to pathology. The activity of the enzyme dimethylarginine dimethylaminohydrolase that metabolises asymmetric methylarginines may be of critical importance in affecting NO pathways in health or disease.

Myasthenia gravis (1993)

To clarify the role of cell-mediated versus humoral immune effector responses in myasthenia gravis (MG), we examined the occurrence of inflammatory cells in muscle from 30 patients with MG, determined the site of accumulation of the cells (at or remote from end-plates), enumerated and immunophenotyped those cells at the end-plate, and evaluated the frequency of deposition of the complement membrane attack complex (MAC) at the end-plate. Seven of 30 patients had well-defined collections of mononuclear cells in muscle (lymphorrhages), but these were not topographically related to the end-plates. Twenty of 30 patients had inflammatory cells (mostly macrophages and T cells) at or near end-plates, but these cells were present at less than 10% of the end-plates, and only seldom was there more than one cell at any end-plate. None of the inflammatory cells penetrated the muscle fiber near the end-plate. All end-plates of all patients immunostained for MAC. The findings reconfirm that the predominant immune effector response in MG is humorally mediated. The lymphorrhages in muscle and other tissues are probably a nonspecific indicator of disturbed immune regulation in MG.
Noninvertible Gabor Transforms (2010)

Time-frequency analysis, such as the Gabor transform, plays an important role in many signal processing applications. The redundancy of such representations is often directly related to the computational load of any algorithm operating in the transform domain. To reduce complexity, it may be desirable to increase the time and frequency sampling intervals beyond the point where the transform is invertible, at the cost of an inevitable recovery error. In this paper we initiate the study of recovery procedures for noninvertible Gabor representations. We propose using fixed analysis and synthesis windows, chosen e.g., according to implementation constraints, and to process the Gabor coefficients prior to synthesis in order to shape the reconstructed signal. We develop three methods for signal recovery. The first follows from the consistency requirement, namely that the recovered signal has the same Gabor representation as the input signal. The second, is based on minimization of a worst-case error. Last, we develop a recovery technique based on the assumption that the input signal lies in some subspace of L <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . We show that for each of the criteria, the manipulation of the transform coefficients amounts to a 2D twisted convolution, which we show how to perform using a filter-bank. When the undersampling factor is an integer, the processing reduces to standard 2D convolution. We provide simulation results demonstrating the advantages and weaknesses of each of the algorithms.
Ultra-compact high-performance MCT MWIR engine (2017)

Size, weight and power (SWaP) reduction is highly desired by applications such as sights for the dismounted soldier or small gimbals for UAVs. But why have high performance and small size of IR systems inevitably exclude each other? Namely, recent development progress in the fields of miniature cryocoolers, short dewars and high operating temperature (HOT) FPAs combined with pitch size reduction opens the door for very compact MWIR-modules while keeping high electro-optical performance. Now, AIM has realized first prototypes of an ultra-compact high-performance MWIR engine in a total volume of only 18cl (60mm length x 60mm height x 50mm width). Impressive SWaP characteristics are completed by a total weight below 400g and a power consumption &lt; 4W in basic imaging mode. The engine consists of a XGA-format (1024x768) MCT detector array with 10&mu;m pitch and a low power consuming ROIC. It is cooled down to a typical operating temperature of ~160K by the miniature linear cryocooler SX020. The dewar uses a short coldfinger and is designed to reduce the heat load as much as possible. The cooler drive electronics is implemented in the CCE layout in order to reduce the required space of the printed boards and to save power. Uncorrected 14bit video data is provided via Camera Link. Optionally, a small image processing board can be stacked on top of the CCE to gain access to basic functions such as BPR, 2- point NUC and dynamic reduction. This paper will present the design, functionalities and performance data of the ultra-compact MCT MWIR engine operated at HOT.
A wireless real-time fall detecting system based on barometer and accelerometer (2012)

Falls threaten the health and life safety of the elderly seriously. And timely medical assistance will help largely to reduce the rate of morbidity- mortality. In this research, a fall detection algorithm was proposed to detect various fall scenarios with high accuracy by analyzing the fall events data obtained from young subjects and the Activities of Daily Life (ADL) data collected from the elderly subjects. Meanwhile a wireless real-time fall detecting system embedding a tri-axial accelerometer, a barometer and ZigBee protocol was developed. The experiment results showed that the real-time system had portability and high reliability on fall detection with a sensitivity of 95.71% and a specificity of 97.78%, for a total set of 320 movements. The system is going to be put into practice on the old subjects in a geracomium in Beijing.
Low-frequency pressure fluctuations in axisymmetric turbulent boundary layers (1980)

Measurements of wall pressure fluctuations under a turbulent boundary layer were made on the fuselage of a sailplane. This flow offers a noise-free environment with a low free stream turbulence level. The axisymmetric boundary layer undergoes natural transition and develops in a zero pressure gradient region. Spectra of the wall pressure were found to decrease at low frequency in agreement with calculations based upon a turbulence–mean shear interaction mechanism. Velocity fluctuations at several positions within and outside the boundary layer were measured and correlated with the wall pressure. A special conditional correlation method was also employed to find the contribution of various velocity fluctuations to the wall pressure. A conditioning signal was formed based upon the signs of u and v and the turbulent–non-turbulent nature of the flow. This signal was time lagged and correlated with the wall pressure signal. It was found that in the outer portion of the boundary layer ( y /δ &gt; 0·5), irrotational motions were more highly correlated with the wall pressure than vortical motion.
Inter-dependence of spectral measures for the singing voice (2006)

This paper deals with investigating the problem of singer identification, by studying some spectral features and the way they depend on each other and on musical performance. Features like the spectral centroid, the tristimulus, the odd/even harmonics relationship are calculated and their evolution during a musical phrase is studied. Their inter-dependence is tested using the Spearman's correlation coefficient. The mentioned features have previously found to be useful for musical instruments description. The results we obtained suggest that the spectral characteristics of the singing voice are mostly determined by the position of the formants, under conscious control of the singer.

Cathodic Protection Surveys of Offshore Platforms - a New Approach (1998)

Abstract Historically, cathodic protection (CP) surveys of offshore platforms have been comprised of a number of steel to seawater potential measurements recorded at selected points on or around the structure. Little or no emphasis has been placed on evaluation of the “resilience” of the CP system; i.e. how hard is the system working, how efficiently, and how much longer will it continue to provide efficient protection. The new approach, which has been used by some operators since 1989 in the Gulf of Mexico, addresses some of these areas without significant increase in the time required to perform the inspection.
Cyclic Resultants (2004)

We characterize polynomials having the same set of nonzero cyclic resultants. Generically, for a polynomial $f$ of degree $d$, there are exactly $2^{d-1}$ distinct degree $d$ polynomials with the same set of cyclic resultants as $f$. However, in the generic monic case, degree $d$ polynomials are uniquely determined by their cyclic resultants. Moreover, two reciprocal (``palindromic'') polynomials giving rise to the same set of nonzero cyclic resultants are equal. In the process, we also prove a unique factorization result in semigroup algebras involving products of binomials. Finally, we discuss how our results yield algorithms for explicit reconstruction of polynomials from their cyclic resultants.
Design and evaluation of multi-resonant unit cells based on liquid crystals for reconfigurable reflectarrays (2012)

A multi-resonant unit-cell based on liquid crystals is proposed for reconfigurable reflectarray antennas. The proposed reflectarray element is made up of three parallel dipoles in the same cell and a tunable liquid crystal as substrate. The performance of the multi-resonant unit cell is compared with that of a single-resonant element in a frequency band from 30 to 40 GHz, showing a significant improvement in bandwidth, range of phase and losses. For a commercial liquid crystal, the proposed element provides a phase range greater than 360° within a 7.4% bandwidth and losses lower than 4.7 dB. These results represent a significant improvement with respect to the single-resonant unit cell based on the same liquid crystal. Finally, the proposed multi-resonant element is validated by measuring the phase response and losses in an X-band waveguide simulator.
Isolation and proteomic characterization of the mid-infection inclusion of Chlamydia trachomatis (2015)

Chlamydia trachomatis ist ein obligat intrazelluläres Humanpathogen, welches sich, nach der Einnistung in seiner Wirtszelle, innerhalb einer membranumhüllten Vakuole, der sogenannten Inklusion, befindet. Die Inklusionsmembran stellt dabei die primäre Kontaktfläche für Pathogen–Wirtszell-Interaktionen dar und definiert dadurch die Nische, in welcher sich die Bakterien vermehren können. Zum ersten Mal beschreiben wir in dieser Arbeit die Isolation und biochemische Charakterisierung der Inklusion von C. trachomatis, mittels herkömmlicher Organellaufreiniungsverfahren und massenspektrometrischer Proteomanalyse an einem zentralen Zeitpunkt der Infektion. Die relative Quantifizierung von Proteinen mittels stabiler isotopenmarkierter Aminosäuren in Zellkultur (SILAC) und die zusätzliche markierungsfreie Quantifizierung erlaubten uns die Darstellung dieses subzellulären Proteoms mit hohem Konfidenzniveau. Mithilfe dieser Methoden haben wir über dreihundert Wirtszellproteine identifiziert und quantifiziert, welche noch nicht als inklusionslokalisiert bekannt waren. Die globale Analyse dieser Daten bestätigte die Rekrutierung vieler Proteine, welche in verschiedenen Membrantransportwegen involviert sind. Zudem fanden sich viele Proteine des retrograden Transportweges, welcher bislang nicht im Zusammenhang mit Chlamydien-Infektionen untersucht wurde. Die detaillierte Analyse dieser Proteine zeigte, dass Sorting Nexine sehr spezifisch zur Inklusion rekrutiert werden. Zudem haben wir mithilfe des unlängst beschriebenen Inhibitors Retro-2 gezeigt, dass retrograder Transport essenziell für die effiziente intrazelluläre Replikation von C. trachomatis ist. Zusammengefasst haben wir eine große Anzahl zuvor unbekannter inklusionsassoziierter Proteine identifiziert und quantifiziert, und auf Basis unserer Daten schlagen wir den retrograden Transportweg als neues Potenzielles Angriffsziel von Therapeutika zur Behandlung von C. trachomatis Infektionen vor.

Reconstructed images of 50 μm transverse and depth resolution have been achieved using this device as a coherence gate to image through 9 mean free paths of turbid scattering medial
A new non-eddy viscosity subgrid-scale model and its application to channel flow (1995)

To date, most large-eddy simulations (LES) have been carried out with eddy viscosity subgrid scale (SGS) models, with only a few exceptions that used the mixed model. Even though the assumptions behind Smagorinsky's model are rather stringent, it has been applied successfully to a variety of turbulent flows. This success is attributed to the ability of eddy viscosity models to drain energy from large scales, thus simulating the dissipative nature of turbulence. Most SGS models are absolutely dissipative, i.e. they remove energy from the large scales at every instant. However, SGS stresses may transfer energy back to the large scales intermittently; this reverse transfer or backscatter is especially important in geophysical flows and in transition. In a fully developed channel flow, there is reverse flow of energy from small to large scales near the walls, but eddy viscosity models are unable to account for this important feature. The dynamic localization eddy viscosity model of Ghosal et al. (1995) allows backscatter by co-evolving an auxiliary equation for the SGS energy; however, the computational cost is considerably larger than for conventional SGS models (Cabot 1994). In this report, a new non-eddy viscosity model based on local approximation of total quantities in terms of filtered ones is introduced; the scale similarity model of Bardina (1983) is a special case of this model. This procedure does not require the assumption of homogeneity, permits backscatter of energy from small to large scales, and is readily implemented in finite difference codes. The results of applying the proposed model to second order finite volume simulation of plane channel flow at high Reynolds numbers (Re(sub b) = 38,000) is described in this report. Greater emphasis is placed on the high Reynolds number flow since it provides a more rigorous test of the SGS model and its potential application. The results are compared to ones produced by the conventional and dynamic Smagorinsky models and the spectral LES of Piomelli (1993).
On spatial rendering and user-centered visualization in 3D (2009)

This paper presents a framework for the rapid isolation and representation of structures from spatially registered image stacks. The introduced framework enables dynamic visualization with next generation volumetric displays, in which image volumes are rendered in real 3D space. Two recent semi-supervised approaches to the problem of segmenting relevant structures are investigated and integrated to yield a generic interactive visualization pipeline. Information obtained from the segmentation process is used to guide layered object reconstruction via the SpatialGL SDK. The reconstructed original objects in 3D may then be selectively visualized on the Perspecta: a spatially-rendered display. Practical considerations, future improvements and applications are discussed.
Laparoscopic Spermatic Vein Ligation in Dogs (1991)

Laparoscopic isolation, ligation, and division of spermatic veins was performed in dogs as a feasibility study. The procedure was successful bilaterally in four adult animals. Successful ligation was confirmed by postoperative laparotomy or by venography. This procedure was simple to perform but was associated with a significant learning curve, as reflected by the operative times, which steadily decreased to less than 15 minutes per side in the final dog. There were no complications.
Amelioration of interface state response using band engineering in III-V quantum well metal-oxide-semiconductor field-effect transistors (2012)

Performance degradation due to interfacial traps is generally considered as one of the main challenges for III-V metal-oxide-semiconductor field-effect-transistors (MOSFETs). In this work, we have investigated the suppression of interface state response using band engineering in III-V quantum well MOSFETs and experimentally verified the concept in the antimonide materials system using a gate-stack consisting of Al2O3/GaSb/InAlSb. It is shown that if the thickness of the interfacial layer of GaSb is scaled down to a few monolayers, the effective bandgap of the interfacial layer increases dramatically due to quantum confinement, which leads to the suppression of interface-trap response.
