Intermodulation distortion in 48 TV channel FM-FDM optical transmission (1991)

The effect of dispersive fibers on multichannel FM video transmission characteristics is experimentally investigated. A directly modulated 1.5 mu m distributed feedback laser diode (DFB-LD) and a LiNbO/sub 3/ external modulator with a continuous-wave (CW) 1.55 mu m DFB-LD are used as optical signal sources. When the 1.3 mu m single-mode fiber (SMF) is used, directly modulated DFB-LDs suffer from second-and third-order intermodulation distortion (IMD). The external modulator realizes good transmission characteristics irrespective of the fiber's dispersion value. This means that external modulators can realize multichannel FM television signal transmission systems that use the standard 1.3 mu m SMF already installed in fiber optic subscriber loops.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Single mode laser with a V-shaped active layer grown by metalorganic chemical vapor deposition: A v-shaped double heterostructure laser (1981)

A single-mode AlxGa1−xAs/GaAs laser of excellent performance was made by metalorganic chemical vapor deposition. The laser has a double heterostructure with a small V-shaped active region of a self-aligned junction stripe geometrically grown on a groove-etched substrate. The self-aligning process was based on a newly found anomalous zinc diffusion phenomenon. The minimum threshold current and the maximum differential quantum efficiency in continuous operation were 15 mA and 65% for a 250-μm-long device. The output power up to 40 mW was attained with an Si3N4 coated device. The beam shape from the laser was nearly circular with an aspect ratio less than 1.5.
THE INFLUENCE OF TWO‐STAGE LOADING ON THE LONGITUDINAL SPLITTING OF UNIDIRECTIONAL CARBON/EPOXY LAMINATES (1996)

Abstract— A review of variable fatigue loading of carbon fibre/epoxy laminates indicates that for two‐stage loading, low‐to‐high loading is generally more damaging than high‐to‐low loading. Damage accumulation under two‐stage loading appears to produce linear damage in some CFRP materials and non‐linear behaviour in others. The behaviour of those materials exhibiting linear damage may be predicted by the Palmgren‐Miner rule. A model is presented for determining the longitudinal split growth in notched unidirectional carbon fibre/epoxy test coupons. The model is able to predict the non‐linear split growth for low‐to‐high loading whilst the linear damage accumulation for high‐to‐low loading may best be determined by use of the Palmgren‐Miner rule.
Pneumococcal Colonization and the Nasopharyngeal Microbiota of Children in Botswana (2018)

S. pneumoniae colonization is associated with characteristic alterations of the nasopharyngeal microbiota of children. Prospective studies should determine if nasopharyngeal microbial composition alters the risk of pneumococcal colonization and thus could be modified as a novel pneumonia prevention strategy.
INTEGRATED SHIP MACHINERY SYSTEMS WHICH RESULT IN SMALL, EFFICIENT DESTROYERS (1980)

ABSTRACT The use of properly seiected integrated ship machinery systems can sharply reduce the size, installed power, and fuel consumption of future Destroyers without reducing payload, speed, range, margins, or stability. One properly chosen subsystem opens the way to using a second superior subsystem, thus a third one, et cetera, forming a sort of beneficient chain reaction. The superior subsystems themselves provide highly leveraged effects on the displacement of the ship. Synergism of this entire chain can result in ship with markedly reduced initial and operating costs. The most essential elements of this system are: aircraft derivative gas turbines; compact, lightweight electric transmissions; large battery energy storage systems; and contrarotating propellers. Adoption of these systems permit secondary high‐leverage subsystems to be used, including efficient ship service power from propulsion turbines and light‐weight maintainable propulsion pods. These changes make total ship rearrangement possible, resulting in major decreases in turbine ducting, propulsion shafting, electric power distribution, and propulsion auxiliaries. Similar benefits in the auxiliary machinery system result from adoption of reverse‐osmosis fresh water production, heat pumps for space heating, glass‐reinforced plastic piping, controllable‐speed, high‐efficiency pump motors, et cetera.
Image-based estimation of ventricular fiber orientations for patient-specific simulations (2011)

Patient-specific simulation of heart (dys)function aimed at personalizing cardiac therapy are hampered by the absence of in vivo imaging technology for clinically acquiring myocardial fiber orientations. In this research, we develop a methodology to predict ventricular fiber orientations of a patient heart, given the geometry of the heart and an atlas. We test the methodology by comparing the estimated fiber orientations with measured ones, and by quantifying the effect of the estimation error on outcomes of electrophysiological simulations, in normal and failing canine hearts. The new insights obtained from the project will pave the way for the development of patient-specific models of the heart that can aid physicians in personalized diagnosis and decisions regarding electrophysiological interventions.
Magnetic Susceptibility of a Spin 1/2 Heisenberg Antiferromagnetic Chain: [3,3′-Dimethyl-2,2′-Thiazolinocyanine]-TCNQ (1996)

Magnetic susceptibility of an organic ion-radical salt, [3,3 ′ -dimethyl-2,2 ′ -thiazolinocyanine]-TCNQ, is measured in the temperature range of 1.4–300 K. Above 10 K, it is quantitatively explained in terms of a S =1/2 Heisenberg antiferromagnetic chain with J / k B =-32.5 K based on the Bonner-Fisher curve. Below 10 K, however, the measured susceptibility seems to show the characteristic slope reported by Eggert et al. down to the ordering temperature T c =1.49 K. Below T c the heat capacity of this salt displays the temperature dependence expected for a gapless spin-wave excitation, which rules out the spin-Peierls transition in this system.
Lack of Frank Agrammatism in the Nonfluent Agrammatic Variant of Primary Progressive Aphasia (2016)

There are nfPPA patients with imaging-supported diagnosis and preserved motor speech skills who do not exhibit frank agrammatism, and this may persist beyond the earliest stages of the illness. Because absence of frank agrammatism is a subsidiary diagnostic feature in the logopenic variant of PPA, this result has implications for differentiation of the nonfluent and logopenic variants, and indicates that PPA patients with nonfluent speech in the absence of frank agrammatism or AOS do not necessarily have the logopenic variant.

Elastomers, Synthetic, Survey (2009)

Abstract The purpose of this article is to provide a brief overview of the materials designated synthetic elastomers and the elastomeric or rubbery state. The term elastomer describes a material that exhibits rubbery properties, ie, that can recover most of its original dimensions after extension or compression. When elastomers are extended or stretched, the individual long‐chain molecules are partially uncoiled, but will retract when the force is removed. The properties of elastomeric materials are greatly influenced by the presence of strong interchain, ie, intermolecular forces that can result in the formation of crystalline domains. Two principal forces that govern the ability of a polymer to crystallize are the interchain attractive forces and the countervailing kinetic energy. In order to cure or vulcanize an elastomer, ie, cross‐link, certain additives are mixed and compounded with the rubber. Specific elastomers discussed are styrene‐butadiene rubber, polybutadiene, polyisoprene, elastomers resistant to age, solvent, and temperature,liquid rubber, and thermoplastics.
Transport, curvature, and geometric potential in photonic topological crystals (2010)

We report on the first experimental realization of topological crystals, solely formed by a geometric potential of an undulated slab waveguide. Transport mechanisms like Bloch oscillations and Zener tunneling are demonstrated.

Metabolic and morphologic properties of single muscle fibers in the rat after spaceflight, Cosmos 1887 (1990)

The adaptation of a slow (soleus, Sol) and a fast (medial gastrocnemius, MG) skeletal muscle to spaceflight was studied in five young male rats. The flight period was 12.5 days and the rats were killed approximately 48 h after returning to 1 g. Five other rats that were housed in cages similar to those used by the flight rats were maintained at 1 g for the same period of time to serve as ground-based controls. Fibers were classified as dark or light staining for myosin adenosine triphosphatase (ATPase). On the average, the fibers in the Sol of the flight rats atrophied twice as much as those in the MG. Further, the fibers located in the deep (close to the bone and having the highest percentage of light ATPase and high oxidative fibers in the muscle cross section) region of the MG atrophied more than the fibers located in the superficial (away from the bone and having the lowest percentage of light ATPase and high oxidative fibers in the muscle cross-section) region of the muscle. Based on quantitative histochemical assays of single muscle fibers, succinate dehydrogenase (SDH) activity per unit volume was unchanged in fibers of the Sol and MG. However, in the Sol, but not the MG, the total amount of SDH activity in a 10-microns-thick section of a fiber decreased significantly in response to spaceflight. Based on population distributions, it appears that the alpha-glycerophosphate dehydrogenase (GPD) activities were elevated in the dark ATPase fibers in the Sol, whereas the light fibers in the Sol and both fiber types in the MG did not appear to change. The ratio of GPD to SDH activities increased in the dark (but not light) fibers of the Sol and was unaffected in the MG. Immunohistochemical analyses indicate that approximately 40% of the fibers in the Sol of flight rats expressed a fast myosin heavy chain compared with 22% in control rats. Further, 31% of the fibers in the Sol of flight rats expressed both fast and slow myosin heavy chains compared with 8% in control rats. Immunohistochemical changes in the MG were minimal. These data suggest that the magnitude and direction of enzymatic activity and cell volume changes are dependent on the muscle, the region of the muscle, and the type of myosin expressed in the fibers. Further, the ability of fibers to maintain normal or even elevated activities per unit volume of some metabolic enzymes is remarkable considering the marked and rapid decrease in fiber volume.

Reciprocal positive regulation of hypoxia-inducible factor 1alpha and insulin-like growth factor 2. (1999)

Hypoxia-inducible factor 1 (HIF-1) activates transcription of genes encoding glucose transporters, glycolytic enzymes, vascular endothelial growth factor, and other proteins involved in O2 homeostasis and tumor progression. The expression and transcriptional activity of the HIF-1alpha subunit is regulated by the cellular O2 concentration. We demonstrate that insulin, insulin-like growth factor (IGF)-1, and IGF-2 induce expression of HIF-1alpha, which is required for expression of genes encoding IGF-2, IGF-binding protein (IGFBP)-2 and IGFBP-3. These data provide a novel mechanism by which HIF-1alpha overexpression may occur in tumor cells and contribute to an autocrine growth factor loop.
Inverted tetrahedron-pyramidal micropatterned polymer films for boosting light output power in flip-chip light-emitting diodes (2015)

We report the improved light output power in gallium nitride-based green flip-chip light-emitting diodes (FCLEDs) employed with inverted tetrahedron-pyramidal micropatterned polydimethylsiloxane (ITPM PDMS) films as an encapsulation and protection layer. The micropatterns are transferred into the surface of PDMS films from the sapphire substrate master molds with two-dimensional periodic hexagonal TPM arrays by a soft imprint lithography method. The ITPM PDMS film laminated on the sapphire dramatically enhances the diffuse transmittance (T(D)) in a wavelength (λ) range of 400-650 nm, exhibiting the larger T(D) value of ~53% at λ = 525 nm, (cf., T(D) ~1% for planar sapphire). By introducing the ITPM PDMS film on the outer surface of sapphire in FCLEDs, the light output power is enhanced, indicating the increment percentage of ~11.1% at 500 mA of injection current compared to the reference FCLED without the ITPM PDMS film, together with better electroluminescence intensity and far-field radiation pattern.
Harnessing fluid-structure interactions to design self-regulating acoustic metamaterials (2014)

The design of phononic crystals and acoustic metamaterials with tunable and adaptive wave properties remains one of the outstanding challenges for the development of next generation acoustic devices. We report on the numerical and experimental demonstration of a locally resonant acoustic metamaterial with dispersion characteristics, which autonomously adapt in response to changes of an incident aerodynamic flow. The metamaterial consists of a slender beam featuring a periodic array or airfoil-shaped masses supported by a linear and torsional springs. The resonance characteristics of the airfoils lead to strong attenuation at frequencies defined by the properties of the airfoils and the speed on the incident fluid. The proposed concept expands the ability of existing acoustic bandgap materials to autonomously adapt their dispersion properties through fluid-structure interactions, and has the potential to dramatically impact a variety of applications, such as robotics, civil infrastructures, and defense systems.
Note on Carbonate Reservoir Rocks, No. 5: Interrelationships Among Various Properties of Carbonates (1987)

Abstract Interrelationships among various properties of carbonate reservoir rocks are presented here. Properties include porosity (intercommunicating and effective), permeability (effective and absolute), bulk density, specific surface area, median pore size, and residual water saturation. Sonic velocity (and permeability) parallel to the bedding and perpendicular to the bedding are also compared.
Carbon flow electrodes for continuous operation of capacitive deionization and capacitive mixing energy generation (2014)

Capacitive technologies, such as capacitive deionization and energy harvesting based on mixing energy (“capmix” and “CO2 energy”), are characterized by intermittent operation: phases of ion electrosorption from the water are followed by system regeneration. From a system application point of view, continuous operation has many advantages, to optimize performance, to simplify system operation, and ultimately to lower costs. In our study, we investigate as a step towards second generation capacitive technologies the potential of continuous operation of capacitive deionization and energy harvesting devices, enabled by carbon flow electrodes using a suspension based on conventional activated carbon powders. We show how the water residence time and mass loading of carbon in the suspension influence system performance. The efficiency and kinetics of the continuous salt removal process can be improved by optimizing device operation, without using less common or highly elaborate novel materials. We demonstrate, for the first time, continuous energy generation via capacitive mixing technology using differences in water salinity, and differences in gas phase CO2 concentration. Using a novel design of cylindrical ion exchange membranes serving as flow channels, we continuously extract energy from available concentration differences that otherwise would remain unused. These results may contribute to establishing a sustainable energy strategy when implementing energy extraction for sources such as CO2-emissions from power plants based on fossil fuels.
A Microprocessor Controlled on-Line Monitor with Computed Trip Points for Long Lived Alpha Emitters in Aerosols (1980)

A four-channel microprocessor-controlled alpha-particle monitor with trip levels computed from background and source activity levels has been designed and constructed. This instrument, intended for monitoring uranium and transuranic particles contained in aerosols, uses virtual impactors to collect the particles and to provide background separation. Alpha spectrometry is subsequently used to separate the desired isotopes. The microprocessor performs trip point calculations, controls 12 four-decade counters and 12 fourdecade liquid crystal displays. It also monitors trip input information from flow and pressure monitors, a key pad for operator input, and controls a small printer used for report generation. This article covers the hardware and software techniques used to implement the device and the theoretical aspects of calculating the sliding scale trip point.
Ferumoxytol as an Intravenous Iron Replacement Therapy in Hemodialysis Patients (2009)

Computing the probability of target detection in dynamic visual scenes containing clutter using fuzzy logic approach (1998)

The probability of detection (Pd) of moving targets in visually cluttered scenes is computed using the fuzzy logic approach (FLA). The FLA is presented as a robust method for the computation and prediction of the Pd of targets in cluttered scenes with sparse data. A limited data set of visual imagery is used to model the relationships between several input parameters: the contrast, vehicle camouflage, range, aspect, width, and experimental Pd. The fuzzy and neurofuzzy models provide predicted Pd values that have 0.9 correlation with the experimental Pd's. The results obtained indicate the robustness of the fuzzy-based modeling techniques and the potential applicability of the FLA to those types of problems that have to do with the modeling of aided or unaided detection of a signal (acoustic, electromagnetic) in any spectral regime.

A UVC Device for Intra‐luminal Disinfection of Catheters: In Vitro Tests on Soft Polymer Tubes Contaminated with Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli and Candida albicans (2011)

Bacterial colonization of central venous catheters (CVCs) causes severe complications in patients. As a result, developing methods to remove and prevent bacterial and fungal colonization of CVCs is imperative. Recently, we have demonstrated that disinfection by radiation of polymer tubes with UVC light is possible. In this paper we present dose-response results using a newly developed UVC disinfection device, which can be connected to a Luer catheter hub. The device was tested on soft polymer tubes contaminated with a pallet of microorganisms, including Candida albicans, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa (ca 10(3) CFU mL(-1)). The tubes were equipped with a modified catheter hub and interfaced to the disinfection device via a middle piece separating the disinfection device from the hub. The contamination lasted for 3 h prior to treatment to simulate an aseptic breach. Our results show UVC killing in a dose and time dependent manner, with no viable counts after 2 min of radiation for bacteria. Killing of C. albicans was obtained at >20 min in an UVC absorbing suspension. We believe our results to be transferable directly to the clinic, and we are currently working on a setup for clinical trial.
Nonlinear Directional Coupler Based on Rb:KTP-Waveguides (1991)

To create ultrahigh-speed long-distance optical fiber communication systems of new generation particularly soliton transmission lines and to implement information optical processing systems into practice it is necessary to develop different functional devices having less than 10 ps high-speed characteristics[1]. The best variant is the application with this aim of light-controlled integrated optical switches and gates, as the pulses of less than 10 fs duration are obtained precisely by the optical methods. Promising from this point of view is the switch based on nonlinear coupled optical waveguides previously used experimentally in the integrated-optical variant on lithium niobate [2] and gallium arsenide [3] base as well as in quartz fiber light guides [4,5].
