Impact of nitric-oxide-mediated vasodilation and oxidative stress on renal medullary oxygenation: a modeling study (2015)

The goal of this study was to investigate the effects of nitric oxide (NO)-mediated vasodilation in preventing medullary hypoxia, as well as the likely pathways by which superoxide (O2(-)) conversely enhances medullary hypoxia. To do so, we expanded a previously developed mathematical model of solute transport in the renal medulla that accounts for the reciprocal interactions among oxygen (O2), NO, and O2(-) to include the vasoactive effects of NO on medullary descending vasa recta. The model represents the radial organization of the vessels and tubules, centered around vascular bundles in the outer medulla and collecting ducts in the inner medulla. Model simulations suggest that NO helps to prevent medullary hypoxia both by inducing vasodilation of the descending vasa recta (thus increasing O2 supply) and by reducing the active sodium transport rate (thus reducing O2 consumption). That is, the vasodilative properties of NO significantly contribute to maintaining sufficient medullary oxygenation. The model further predicts that a reduction in tubular transport efficiency (i.e., the ratio of active sodium transport per O2 consumption) is the main factor by which increased O2(-) levels lead to hypoxia, whereas hyperfiltration is not a likely pathway to medullary hypoxia due to oxidative stress. Finally, our results suggest that further increasing the radial separation between vessels and tubules would reduce the diffusion of NO towards descending vasa recta in the inner medulla, thereby diminishing its vasoactive effects therein and reducing O2 delivery to the papillary tip.
Solving systems of nonlinear equations using the nonzero value of the topological degree (1988)

Two algorithms are described here for the numerical solution of a system of nonlinear equations F(X) = Θ, Θ(0,0,…,0)∈ ℝ, and F is a given continuous mapping of a region 𝒟 in ℝ n into ℝ n . The first algorithm locates at least one root of the sy stem within n -dimensional polyhedron, using the non zero v alue of the topological degree of F at θ relative to the polyhedron; th e second algorithm applies a new generalized bisection method in order to compute an approximate solution to the system. Teh size of the original n -dimensional polyhedron is arbitrary, and the method is globally convergent in a residual sense. These algorithms, in the various function evaluations, only make use of the algebraic sign of F and do not require computations of the topological degree. Moreover, they can be applied to nondifferentiable continuous functions F and do not involve derivatives of F or approximations of such derivatives.
[A new method for the preparation of potassium ferrate and spectroscopic characterization]. (2010)

Calcium hypochlorite was used as the raw material for preparation of the high purity potassium ferrate. The study includes the effects of reaction temperature, recrystallization temperature, reaction time, Ca(ClO)2 dosage, and the amount of calcium hypochlorite on the yield. It was determined that when the reaction temperature was 25 degrees C, recrystallization temperature 0 degree C and reaction time 40 min, the yield was more than 75%. The purity was detected by direct spectrophotometric method to be more than 92%. The product was characterized by infrated spectrum(IR), X-ray diffraction (XRD) and ultraviolet spectrum (UV) methods and proved to be potassium ferrate that was prepared by calcium hypochlorite as the raw material.
SoCar: A Social Car2Car Framework to Refine Routes Information Based on Road Events and GPS (2015)

GPS-based applications make travelling easier, supplying information about routes, such as real-time traffic, Estimated Time of Arrival, faster or cheaper path. These applications exploit digital maps supplied by specific companies, often updated also thanks to user-submitted data. The aim of this work is to show an event driven system for territory mapping and monitoring, using multi-hop wireless networks, relying on C2X communication and on VANETs in general. The idea is to keep road maps up to date automatically and autonomously, exploiting a collaborative communication of events in social networking style, without the need for a centralized communication system. Moreover, it is possible to enhance standard map data introducing two more layers: an events layer, automatically built by the events detected by SoCar clients, characterized by a short life span, and a prevision area layer, derived from events layer statistics, where data point are clustered in proper spatial neighborhood. Both these layers contribute to choose the most convenient route, the events layer for the short term and the prevision area layer for the long term.

Do probiotics have a therapeutic role in gastroenterology (2006)

Several hundred species of bacteria inhabit the gut, and affect its cell biology, morphology and homeostasis. Many bacteria are however potential pathogens, especially if the integrity of the epithelial barrier is physically or functionally breached. Conversely, the interaction between host and commensal microbes can confer important health benefits. This has led to commercial and public interest in "probiotics", live microbes principally taken as food supplements. Might probiotics also be used in disease therapy? Experimental evidence that probiotics modulate gut physiology, particularly barrier integrity and immunological function, underpins exciting new gastroenterological research. We discuss below the scientific basis for probiotic effects and present a critical perspective for their use in relation to gastrointestinal disease.

Volatilization of Pesticides from Soil: Processes and Measurement (1991)

The volatilization of pesticides from soil is reviewed from the standpoint of the magnitude of volatilization losses, mechanisms involved, factors influencing volatilization rates, and progress in developing prediction models. The volatilization of soil incorporated pesticides is controlled by their rate of movement away from the surface, their effective vapor pressure at the surface or within the soil, and their rate of movement through the soil to the vaporizing surface. The use of a model for classifying and screening pesticides for their environmental behavior based on their physical and chemical properties is demonstrated and data on volatilization rates are compared with predictions from the model.
Measurements on light emission and current distribution in avalanching epitaxial diodes (1974)

Silicon diodes built in epitaxial layers of varying parameters were found to exhibit two distinct modes of light-emission dependence on avalanching current prior to secondary breakdown. The modes depend on whether the depletion layer extends to the substrate interface prior to avalanche or not. Current distribution is inferred from the light curve and a possible mechanism leading to the secondary breakdown is suggested.
Interferon gene expression signature in rheumatoid arthritis neutrophils correlates with a good response to TNFi therapy (2014)

IFN-response genes are significantly up-regulated in RA neutrophils compared with healthy controls. Higher IFN-response gene expression in RA neutrophils correlates with a good response to TNFi therapy.
Phase-mismatch dependence of efficiency of wave generation through four-wave mixing in a single-mode optical fiber (1987)

The generation wave efficiency with respect to phase mismatch in the four-wave mixing process is clarified experimentally in a single-mode fiber transmission line at 825 nm wavelength. The generated power of approximately 20 pW is measured successfully for input signal powers below 1 mW by the technique utilizing a heterodyne receiver and lock-in detector. The calculated efficiency as a function of the equivalent frequency separation can well explain and reflect the results obtained experimentally. Furthermore, the efficiency at zero chromatic dispersion wavelengths of 1.3 and 1.55 μm is also discussed considering chromatic dispersion slope against wavelength.

Broadband electronically-tuned microwave filters (2005)

It has been suggested that single crystals of yttrium iron garnet (YIG) can be used in the construction of low-loss microwave filters which can be tuned by means of an applied dc magnetic field. This paper will discuss practical broadband circuits in coaxial line and waveguide for both single-tuned and multiple-tuned band-pass and band-reject filters using such YIG crystals. One version of a band-pass filter has operated with electronic tuning from 2000 mc to 6500 mc. The insertion loss was 3 db at 2000 mc, 1 db at 4000 mc, and 0.7 db at 6500 mc, with bandwidths ranging from 18 mc to 40 mc. A packaged version of this filter will be described which utilizes a combination of permanent magnets and solenoids for tuning. The complete filter weighs less than 2-1/2 lb. and can be tuned <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\pm 1000</tex> mc from 3000 mc with a power consumption of 5 watts.
All-optical switching in a laterally coupled microring resonator by carrier injection (2003)

We demonstrate all-optical switching in a laterally coupled GaAs-AlGaAs microring resonator by carriers injections. The ring waveguide is optically pumped just above its bandgap energy, which results in a temporal tuning of the microring resonant wavelengths by the refractive index change due to the induced carriers. A switching window of 20 ps could be obtained and is only limited by the carrier recombination time. A switching energy of a few tens of picojoules per pulse is used and has resulted in a 1.2-nm wavelength shift of the microring resonance.
INEQUALITY AND POVERTY IN COMPARATIVE PERSPECTIVE (1997)

Members of modern societies use a wide range of goods and services to effect their participation in social relations, and their sense of social identity. As a part of common cultural understandings, members assume the necessity for particular material underpinnings to their activities in carrying out the social roles which constitute participation in their communities. Because these are highly stratified societies, the level of economic resources available to individuals and families varies greatly. People have a lively sense of what different levels imply in terms of both with whom an individual is likely to participate, and the kind of activities in social participation which are feasible. The definition of poverty adopted by the European Community in 1984 reflects a conception of poverty grounded in an understanding of the nature of social stratification in prosperous industrial societies: The poor shall be taken to mean persons, families, and groups of persons whose resources (material, cultural, and social) are so limited as to exclude them from the minimum acceptable way of life in the member state in which they live. This paper summarizes several studies concerned with cross-national comparisons of income

Gravimetric Analysis of the Nonvolatile Residue from an Evaporated Droplet, Using the Quartz Crystal Microbalance/Heat Conduction Calorimeter (2006)

Abstract A quartz crystal microbalance/heat conduction calorimeter (QCM/HCC) has been used to determine the nonvolatile residue at the parts-per-million level in 10 µL droplets of methanol and a 45 µL droplet of water. The QCM was used to measure the mass of the nonvolatile residue, and the calorimeter was used to determine the mass of the solvent by the heat required to evaporate the droplet.
Dynamic dependencies and performance improvement (2008)

The art of performance tuning is, alas, still an art; there are few tools to help predict the effects of changes that are motivated by performance needs. In this work, we present dynamic dependency modeling techniques for predicting the effects of configuration changes. These techniques utilize a simple, exterior model of the system under test, and only require codifying the nature of dependencies between subsystems. With a few examples, we demonstrate how to utilize these models to predict the impact of system changes. Using simple tools and a reasoning process, it is possible to answer many questions about possible performance enhancements. The impact of this work is to advance performance tuning a small amount – from being an art toward becoming a science.
Lipid peroxidation and antioxidant status is affected by different vitamin E levels when feeding fish oil (1994)

The protective role of vitamin E and changes in the status of several physiological antioxidants after feeding rats a fish oil diet were investigated. Six-week-old male Sprague-Dawley rats were divided into four groups and fed experimental diets for 8 wk. Three fish oil (FO) groups were fed a menhaden fish oil and soybean oil (SO) (9:1) mixture as 10% (w/w) of the diet. These groups were provided with < or = 3, 45 or 209 IU of vitamin E/kg diet. One SO group was used as control and was fed < or = 45 IU of vitamin E/kg diet. Plasma vitamin E levels, when expressed as vitamin E per mL plasma, were extremely low in the group fed FO and < or = 3 IU of vitamin E, and were lower in the groups fed FO than in the group fed SO. However, plasma vitamin E levels when expressed per mg plasma lipid were higher in the FO groups provided with < or = 45 and 209 IU of vitamin E than in the SO group. Compared with the SO group, plasma levels of thiobarbituric acid reactive substances (TBARS), when expressed per mg lipid, were higher in the three FO groups, plasma retinol levels were lower in the FO groups provided with < or = 3 and 45 IU of vitamin E, and ascorbic acid levels were lower only in the FO group provided with < or = 3 IU of vitamin E. Blood glutathione (GSH) levels were lower in all three FO groups than in the SO group.(ABSTRACT TRUNCATED AT 250 WORDS)
United Iterative Reconstruction for Spectral Computed Tomography (2014)

Spectral computed tomography (CT) has attracted considerable attention because of its energy-resolving capability in identifying and discriminating materials. The use of a narrow energy bin can improve energy resolution. However, a narrow energy bin has high noise ratio, which degrades the imaging quality of spectral CT. To address this problem, this study exploits the structure correlations of images in the energy domain and proposed two types of united iterative reconstruction (UIR) algorithms. One type uses the well-reconstructed broad-spectrum image, with all available photons, as a constraint, whereas the other type uses a pseudo narrow-energy image, which is estimated with the use of our proposed structure-coupling (SC) method, as a constraint. The SC method utilizes local structures to connect images that are reconstructed with broad-spectrum and narrow-energy CT datasets. Given a broad-spectrum image, the SC method can accurately estimate its corresponding narrow-energy image. Results show that UIR algorithms significantly outperform conventional iterative reconstruction algorithms for narrow-energy image reconstruction in spectral CT. Among the UIR algorithms, SC-UIR yields the best results.
Efficient GSVD Based Multi-User MIMO Linear Precoding and Antenna Selection Scheme (2009)

We present a multi-user multiple-input multiple-output (MU-MIMO) preceding scheme utilizing generalized singular value decomposition (GSVD). Our work is motivated by the precoding scheme developed by Sadek, Tarighat, and Sayed that maximizes the signal to leakage and noise ratio (SLNR), in which the precoding weight is obtained by the generalized eigenvalue decomposition (GEVD). However, the covariance matrix utilized in GEVD becomes close to be singular as the signal to noise ratio goes high. To improve the numerical accuracy, a GSVD based algorithm is exploited in this paper and a novel method is derived to compute the precoding weights for multiple users by removing redundant computational loads rather than repeating the GSVD algorithm for each user. In addition, we propose a technique to speed up the GSVD based precoding algorithm by preprocessing using the QR decomposition. Finally, to improve the system performance, the antenna selection scheme using GSVD is also proposed which does not require the exhaustive search to choose the active antennas.
Low-level processing for real-time image analysis (2005)

This paper describes a system that detects object outlines in television images in real-time. A high-speed pipeline processor transforms the raw image into an edge map and a microprocessor, which is integrated into the system, clusters the edges and represents them as chain codes. Image statistics, useful for higher level tasks such as pattern recognition, are computed by the micro processor. Peak intensity and peak gradient values are extracted within a programmable window and are used for iris and focus control. The algorithms implemented in hardware and the pipeline processor architecture are described. The strategy for partitioning functions in the pipeline was chosen to make the implementation modular. The microprocessor interface allows flexible and adaptive control of the feature extraction process.
Cascaded Multilevel Inverters with Reduced Structures Based on a Recently Proposed Basic Units: Implementing a 147-level Inverter (2017)

A multilevel inverter is capable of generating high-quality stepwise pseudo-sinusoidalvoltage with low THD , applicable to high-power and high-voltage systems. These types of topologiesmay require a large number of switches and power supplies. This leads to much cost, large size, andcomplicated control algorithms. Thus, newer topologies are being proposed to decrease the numberof power electronic devices for a large number of levels in output voltage. Recently, a new multilevelinverter has been reported in the literature to reduce component count. Its structure requires a lowernumber of active switches as compared to the existing ones. The available literature presents ageneralization of the topology with an especial asymmetrical sources ratio, but no investigations aremade for other symmetrical or asymmetrical sources ratio with cascaded configurations. This studypresents a comprehensive analysis of cascaded topologies with the proposed basic units. The topologyis analysed for both symmetric and asymmetric DC source configurations. Also, two algorithms forasymmetric source configuration suitable for cascaded structures are proposed. Moreover, the designand simulation of a 147-level inverter are presented under an optimal number of DC sources and powerswitches. Furthermore, experimental validation is performed by implementing a laboratory prototype.
Comparative studies on tree pollen allergens. XIV. Characterization of the birch (Betula verrucosa) and hazel (Corylus avellana) pollen extracts by horizontal 2-D SDS-PAGE combined with electrophoretic transfer and IgE immunoautoradiography. (1988)

The crude aqueous extracts of birch (Betula verrucosa) and hazel (Corylus avellana) pollen were characterized by horizontal isoelectric focusing (IEF) and one-dimensional and two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis (1-D and 2-D SDS/PAGE). Isoelectric focusing reference patterns obtained in pH 3.5 to 9.5 gradient gels contained 31 and 41 bands while the 2-D patterns consisted of 51 and 72 protein spots, respectively. Electrophoretic transfer to nitrocellulose membranes and subsequent 125I-immunoautoradiography demonstrated IgE binding in the region between pH 4.8 and 5.4 for both extracts. The main allergenic reactivities of this pH region were distributed by SDS/PAGE to the molecular weights of 29.5, 17, and 12.5 kilodaltons for birch and 15.5 and 12 kilodaltons for hazel. The high resolving power and the independence of rabbit antibodies were considered the major advantages of the described 2-D methodology as compared with conventional crossed immunoelectrophoretic and radioimmunoelectrophoretic techniques.
Novel targeted therapies in peripheral T cell lymphoma. (2013)

Peripheral T cell lymphomas (PTCL), non-Hodgkin lymphomas characterized by having features of T cells that have matured in the thymus, are a heterogeneous group of clinical entities. Compared with B cell lymphomas, they are less common, more difficult to diagnose and classify, more aggressive, and have inferior outcomes with current treatment paradigms. They are also less completely understood in terms of how different PTCL types correspond to normal T cell development, and in identifying cell signaling pathways as targets for new therapies. Recent studies with novel targeted therapies as single agents or in combination with other drugs have illustrated promising outcomes both for relapsed and frontline PTCL. We first briefly review classification, prognostic indices, and results of initial therapy of various T cell lymphomas. We then review recent studies of chemotherapy, monoclonal antibody-based therapy directed at cell surface targets, small molecule inhibitors of intracellular targets such as histone deacetylases and the proteasome, and agents that disrupt stromal interactions. Investigations that enhance our knowledge of T cell molecular biology and integrate novel targeted agents into the treatment algorithm for PTCL will be keys to improved outcomes for patients with PTCL.
