[Study on the dendritic cell subsets in peripheral blood and its relationship with the expressions of T-bet and GATA-3 in lymphocytes in severe aplastic anemia]. (2008)

Either DC1/DC2 or T-bet/GATA-3 ratio might become an index to estimate immune imbalance. High-expressed T-bet was related to the progress of SAA. In patients with SAA, DC1/DC2 ratio returns to normal range later than that of routine blood test does, indicating that immunosuppressive therapy should not be withdrawn too earlier.

Predictive Congestion Avoidance in Wireless Mesh Network (2015)

Congestion avoidance is a vital part in improving the Quality of service (QoS) in Wireless Mesh Network (WMN). A preventive congestion avoidance algorithm is proposed in this paper which predicts the congestion before it really happens in the network by using different statistical analysis models which analyze historical traffic data in the network with some level of certainty to predict the future traffic data. Our proposed algorithm improves the Hybrid Wireless Mesh Protocol (HWMP) routing protocol used in IEEE 802.11s MAC layer standard. Based on the predicted link congestion, rerouting algorithm is implemented in order to assure the load balancing and to prevent congestion over WMN network. Simulation results show that our proposed algorithm outperforms other algorithms in the literature in terms of throughput, end-to-end delay, and fairness.
Cylinder Pressure-Based Control of Pre-Mixed Diesel Combustion (2007)

<div class="htmlview paragraph">Implementation of real-time combustion feedback for use in closed-loop combustion control is a technology that has potential to assist in the successful production implementation of advanced diesel combustion modes. Low-temperature, pre-mixed diesel combustion is presently of interest because it offers the ability to lower the engine-out emissions of oxides of nitrogen (NOx) and particulate matter (PM). The need for lowering these two emissions is driven by tighter regulations enacted worldwide, especially the NOx limits in the United States. Reducing engine-out emissions eases the need for additional exhaust aftertreatment devices and their associated cost and mass.</div> <div class="htmlview paragraph">In this paper we will describe an experimental cylinder pressure-based control system and present both steady-state and transient results from a diesel engine employing a pre-mixed type of combustion. Data are presented showing engine operation with the control system enabled and disabled, highlighting the control effectiveness of the real-time cylinder pressure feedback.</div>
Robust smooth magneto tell uric transfer functions (1996)

Robust estimates of the magnetotelluric (MT) transfer function are found using an iterative reweighted method on time series data corrected for outliers and gaps. The MT transfer function, composed of several analytic functions smoothly varying in frequency, is used to represent the frequency-domain relationship between electric and magnetic time series. The smoothly varying transfer function facilitates identification and removal of electric and magnetic outliers (spikes), construction of the frequencyand time-domain weights used for obtaining robust smooth and band-averaged estimates, and separation of the time series into MT and correlated noise signals if a remote site exists that is free of the correlated noise. Errors in the transfer function are calculated using jackknife estimates of the solution covariance. The method is tested on: time series from a relatively clean MT site in central California; a test time series based on Tucson magnetic time series plus synthetic noise for a given transfer function; and time series from the Larderello geothermal region in central Italy where there are strong signals from d.c. electrified railways.

Effects of the Dietary Approaches to Stop Hypertension (DASH) Diet on the Pressure-Natriuresis Relationship (2003)

Blood pressure-lowering mechanisms of the Dietary Approaches to Stop Hypertension (DASH) diet, rich in fruits, vegetables, and low-fat dairy foods, were analyzed based on the pressure-natriuresis relationship. Participants (n=375) were randomly assigned to control or DASH diet groups by using a parallel-group design. They then ate their assigned diet for 3 consecutive 30-day intervention feeding periods, during which sodium intake varied among 3 levels by a randomly assigned sequence. Urinary sodium excretion rate and mean arterial pressure were measured at the end of each sodium intake level. Mean arterial pressure and urinary sodium excretion were plotted on x and y axes, respectively, for participants eating control and DASH diets and were modeled as linear relationships for simplicity to allow the estimation of the extrapolated x-intercept and slope of the relationships. The DASH diet steepened the slope of the relationship (29.5+/-3.4 vs 64.9+/-13.1 [mmol/d]/mm Hg, P=0.0002) without significantly shifting the x-intercept (94.1+/-0.5 vs 93.2+/-0.6 mm Hg, NS) of the relationship. These data suggest a natriuretic action of the DASH diet.
Spatio-Temporal Inception Graph Convolutional Networks for Skeleton-Based Action Recognition (2020)

Skeleton-based human action recognition has attracted much attention with the prevalence of accessible depth sensors. Recently, graph convolutional networks (GCNs) have been widely used for this task due to their powerful capability to model graph data. The topology of the adjacency graph is a key factor for modeling the correlations of the input skeletons. Thus, previous methods mainly focus on the design/learning of the graph topology. But once the topology is learned, only a single-scale feature and one transformation exist in each layer of the networks. Many insights, such as multi-scale information and multiple sets of transformations, that have been proven to be very effective in convolutional neural networks (CNNs), have not been investigated in GCNs. The reason is that, due to the gap between graph-structured skeleton data and conventional image/video data, it is very challenging to embed these insights into GCNs. To overcome this gap, we reinvent the split-transform-merge strategy in GCNs for skeleton sequence processing. Specifically, we design a simple and highly modularized graph convolutional network architecture for skeleton-based action recognition. Our network is constructed by repeating a building block that aggregates multi-granularity information from both the spatial and temporal paths. Extensive experiments demonstrate that our network outperforms state-of-the-art methods by a significant margin with only 1/5 of the parameters and 1/10 of the FLOPs.

Uniform Direct-Current Discharges in Atmospheric Pressure He/N2/CO2 Mixtures Using Gas Additives (1972)

Uniform direct-current discharges in atmospheric-pressure mixtures of He/N2/CO2 have been achieved by the use of an organic gas additive. Best results were obtained using xylene as an additive with a concentration of 0. 5% in a 90/5/5 gas mixture. Observed current densities were limited by external circuitry, but uniform pulsed discharges with current densities over 3 A/cm2 were obtained when the dc discharge was pulsed.
Conduction block induced by high frequency AC stimulation in unmyelinated nerves (2007)

The potential neurophysiological applications of high frequency AC stimulation (HFAC) in blocking conduction has led to a series of experimental and modeling studies analyzing the effect of HFAC conduction block on mixed nerves. However, many of these computational studies have been based on axon models that are perhaps not valid for the nerves under study. The isolated response of unmyelinated nerves to HFAC has also not been previously studied. In this study, 5-50 kHz sinusoidal HFAC stimulation waveforms were used to reversibly block conduction through the unmyelinated nerve fibers of Aplysia. Unlike myelinated nerves, the minimum HFAC amplitude for blocking conduction in these nerves showed a non-monotonic behavior with frequency. The Hodgkin-Huxley model did not accurately predict the experimentally observed trends but modifying the model to incorporate a frequency-dependent membrane capacitance resulted in a significant change in the high frequency response of the model while still preserving the standard characteristics of action potential propagation.
H2S Suppression During the Desulfation of a Lean NOx Trap with a Nickel-Containing Catalyst (2005)

<div class="htmlview paragraph">Lean NO<sub>x</sub> Traps are used to treat the NO<sub>x</sub> emissions from lean-burn engines by storing the NO<sub>x</sub> under lean conditions and reducing the NO<sub>x</sub> during periodic rich excursions. However, sulfur poisons the adsorption sites of the traps. The sulfur can be removed from the NO<sub>x</sub> trap by operating rich at high temperatures for several minutes. This results in the release of some SO<sub>2</sub> but also large quantities of H<sub>2</sub>S, which is a source of customer dissatisfaction that must be reduced or eliminated. This paper describes the use of a nickel-containing catalyst and air/fuel control to maximize the release of SO<sub>2</sub> and minimize the emissions of H<sub>2</sub>S during the desulfation of a lean NO<sub>x</sub> trap. We present laboratory and vehicle data with a nickel-containing catalyst located downstream of a lean NO<sub>x</sub> trap during desulfations of the trap. The nickel effectively reduced the emissions of H<sub>2</sub>S during the desulfation while improving the robustness to fluctuations in the air/fuel control.</div>
High‐efficiency PV inverter with SiC technology (2017)

A high‐efficiency, three‐phase, solar photovoltaic (PV) inverter is presented that has low ground current and is suitable for direct connection to the low voltage (LV) grid. The proposed topology includes a three‐phase, two‐level (2L) voltage source inverter (VSI) and an active common‐mode (CM) filter. The VSI utilises silicon (Si) insulated‐gate bipolar transistors with silicon carbide (SiC) diodes to reduce switching losses and provide very high efficiency. The active CM filter reduces the high level of CM voltage associated with the three‐phase 2L VSI. The active CM filter is controlled so that the PV ground current is reduced to acceptable levels, even when the PV inverter is connected directly to a LV grid with low‐impedance grounding. 50 and 100 kW prototypes are presented that demonstrate high efficiency.
A CMOS cubic voltage generator for a temperature compensated crystal oscillator (TCXO) (2008)

A cubic function generator is an essential component in TCXOs to compensate for the frequency variation of quartz resonators during temperature change. The authors present a fully analog CMOS cubic function generator circuit. It is composed of analog variable gain amplifiers and a voltage adder. The circuit generates an exact cubic function that represents a quartz resonator’s frequency versus temperature characteristic. Adjusting the parameters of the cubic wave and adding the higher order terms for more precise control can be done easily in this design. The design is implemented and fabricated in TSMC 0.35 μm technology.
Isolation and characterization of circulating feline leukemia virus-immune complexes from plasma of persistently infected pet cats removed by <i>ex vivo</i> immunosorption. (1982)

IgG and circulating IgG immune complexes (CIC) were purified from plasma of three pet cats persistently infected with feline leukemia virus (FeLV) by adsorption to, and elution from, Staphylococcus aureus Cowan I. CIC were then separated from free IgG by sucrose gradient ultracentrifugation and were analyzed for the presence of FeLV structural proteins and corresponding specific antibodies. Radioimmunoprecipitation analysis indicated that FeLV envelope (gp70) and major core (p30) proteins, along with cat IgG heavy and light chains, were present in the CIC from all three cats. Further analysis of the CIC from one of the cats also revealed the presence of FeLV core proteins p15 and p12. IgG purified from isolated CIC was also shown to bind specifically to purified FeLV gp70, p30, and p15. These data provide direct evidence for FeLV-specific CIC in the plasma of persistently viremic pet cats, and suggest these animals are immunologically response to the virus even though free antibodies against the major structural proteins cannot be demonstrated in standard assays.

Vision and consistency : USAID support of Al Amana and the law on microfinance in Morocco (2003)

This case study describes how the United States Agency for International Development (USAID) pursued a vision for large-scale microfinance in Morocco by creating a best-practice microfinance institution and facilitating an enabling legal framework. As an investor, USAID built a self-sustaining microfinance institution (MFI) that operates at a scale reached by only one other MFI in the Middle East and North Africa region.
Low complexity group detectors for multirate transmission in TD-CDMA 3G systems (2002)

In this paper, we address the problem of the downlink detection in a mobile radio system with hybrid time-division and code-division multiple access, wherein the deployment of orthogonal variable spreading factor codes allows for multirate communication. Accounting for a multipath propagation channel, we focus on the detection of data carried by a group of codes (ranging from a single code, to all active intracell codes) destined to the same mobile station and on the simultaneous rejection of the interference due to the complementary set of active intracell codes. We tackle both the problems of intersymbol interference (ISI) suppression, and multiple access interference (MAI) mitigation, and show when it is convenient to treat these issues together. Specifically, the feasibility of linear detectors based on the zero forcing and the minimum mean square error (MMSE) criterion is investigated, with the aim to mitigate both ISI and MAI. A unified low-complexity formulation based on a sliding window algorithm is proposed for this class of linear detectors. The numerical results validate the proposed receiver structure, indicating that the attainable performance is very close to the single user lower bound up to moderate system loads.
Homocysteine Elevation in Sickle Cell Disease (2000)

Patients with sickle cell disease have elevated plasma concentrations of homocysteine in spite of elevated plasma folate levels and vitamin B12 concentrations similar to those observed in controls. Based on these data, we hypothesize that the concentration of folate required to normalize plasma homocysteine levels in patients with sickle cell disease may be higher than that of normal controls and that patients with sickle cell disease have a higher nutritional requirement for folic acid than the general population.
The role of sulphate conjugation in the metabolism and disposition of oral and intravenous paracetamol in man. (1984)

The effects of paracetamol dose (5 and 20 mg/kg) and route of administration (intravenous and oral) on the urinary excretion of paracetamol and its glucuronide, sulphate, cysteine and mercapturic acid conjugates were studied in five healthy subjects. The fractional urinary excretion of unchanged paracetamol and its conjugates was independent of the route of administration at both dose levels, suggesting that the gastrointestinal tract is not an important site for paracetamol metabolism. The percentage of the dose excreted as the sulphate conjugate was significantly higher after 5 than after 20 mg/kg (37.7% and 33.3% respectively) and this is consistent with saturation of sulphate conjugation. No significant effect of paracetamol dose upon the area under the plasma concentration-time curve (AUC), corrected for dose, was found for the sulphate or glucuronide conjugates. The total plasma clearance of paracetamol and the renal clearance of the sulphate conjugate were significantly higher after the 5 than the 20 mg/kg dose (331 +/- 42 ml/min and 295 +/- 48 ml/min; 273 +/- 74 ml/min and 205 +/- 46 ml/min respectively). The oral systemic availability of paracetamol was 80% and independent of dose.
Identification of the structural gene encoding the SH-activated hemolysin of Listeria monocytogenes: listeriolysin O is homologous to streptolysin O and pneumolysin (1987)

By immunoblotting with an antiserum raised against purified listeriolysin O, we have detected the presence of a truncated protein of 52 kilodaltons in culture supernatants of a Tn1545-induced nonhemolytic mutant of Listeria monocytogenes (J.L. Gaillard, P. Berche, and P. Sansonetti, Infect. Immun. 52:50-55, 1986). The region of insertion of the transposon has been cloned and sequenced. The transposon had inserted in an open reading frame the listeriolysin O gene. The deduced amino acid sequence of this open reading frame revealed that listeriolysin O is homologous to streptolysin O and pneumolysin, although homologies were not detectable at the DNA level.
Enabling Oxygen–Sulfur Exchange Reaction to Produce Semicrystalline Copolymers from Carbon Disulfide and Ethylene Oxide (2020)

This work describes the first example of semicrystalline poly(thiocarbonate)s from carbon disulfide (CS<sub>2</sub> ) and ethylene oxide (EO), two mass producible low-cost monomers. Lewis acid/base pairs (LPs) exhibit high activity (EO conversion up to >99%, 8 h) in catalyzing the copolymerization under low Lewis pair/monomer ratio of 1:1500. Oxygen-sulfur exchange reaction (O-S ER) during the copolymerization of CS<sub>2</sub> and EO, the generation and mutual copolymerization with COS, CO<sub>2</sub> , and episulfide, is harnessed to introduce crystallizable segments [SC(O)O and SC(S)S] in the copolymer. The type of Lewis base is found to have a great impact on the chain microstructure and the crystalline properties. The formed copolymers with melting point from 117.7 to 245.3 °C are obtained. The maximum crystallinity is estimated to be 78% based on the powder wide-angle X-ray diffraction pattern. This work provides a general method to prepare semicrystalline sulfur-containing polymers.
Field Testing of Utility Robots for Lunar Surface Operations (2008)

Since 2004, NASA has been working to return to the Moon. In contrast to the Apollo missions, two key objectives of the current exploration program is to establish significant infrastructure and an outpost. Achieving these objectives will enable long-duration stays and long-distance exploration of the Moon. To do this, robotic systems will be needed to perform tasks which cannot, or should not, be performed by crew alone. In this paper, we summarize our work to develop "utility robots" for lunar surface operations, present results and lessons learned from field testing, and discuss directions for future research.
Acellular Gelatinous Material of Human Umbilical Cord Enhances Wound Healing: A Candidate Remedy for Deficient Wound Healing (2017)

Impaired wound healing is a severe clinical challenge and research into finding effective wound healing strategies is underway as there is no ideal treatment. Gelatinous material from the umbilical cord called Wharton's jelly is a valuable source of mesenchymal stem cells which have been shown to aid wound healing. While the cellular component of Wharton's jelly has been the subject of extensive research during the last few years, little is known about the de-cellularized jelly material of the umbilical cord. This is important as they are native niche of stem cells. We have isolated Wharton's jelly from umbilical cords and then fractionated acellular gelatinous Wharton's jelly (AGWJ). Here, we show for the first time that AGWJ enhances wound healing <i>in vitro</i> as well as <i>in vivo</i> for wounds in a murine model. <i>In vivo s</i>taining of the wounds revealed a smaller wound length in the AGWJ treated wounds in comparison to control treatment by enhancing cell migration and differentiation. AGWJ significantly enhanced fibroblast cell migration <i>in vitro</i>. Aside from cell migration, AGWJ changed the cell morphology of fibroblasts to a more elongated phenotype, characteristic of myofibroblasts, confirmed by upregulation of alpha smooth muscle actin using immunoblotting. AGWJ treatment of wounds led to accelerated differentiation of cells into myofibroblasts, shortening the proliferation phase of wound healing. This data provides support for a novel wound healing remedy using AGWJ. AGWJ being native biological, cost effective and abundantly available globally, makes it a highly promising treatment option for wound dressing and skin regeneration.
