Adsorption and desorption behavior of water and organic vapor of allophanic soil<b>–</b>templated porous carbon materials (2012)

We have synthesized several kinds of porous carbon material by template method using 2 kinds of natural allophanic soil purchased in Japan as template materials. To determine the hydroscopic properties of the templated porous carbon specimens, we measured their water adsorption and desorption isotherms around room temperature (283, 293 and 298 K). We also measured porous and chemical properties of the templated porous carbon specimens, and investigated the relationships between pore development and their water isotherms. The features of the isotherm curves of the templated porous carbon specimens were different from those of common activated carbon used as a reference, and the features in this study were dependent on template materials rather than carbon ingredients. Some of the templated porous carbon specimens had water adsorption isotherms that rose sharply at approximately 80% relative humidity (RH), and the desorption isotherms dropped off at 60% RH. The results indicate the possibility of application of these specimens as effective adsorbents that are not susceptible to moisture as compared with common activated carbon. The specimens are also assumed to be useful as humidity control materials.
IMPACT OF FIRES IN DIFFERENT MANAGEMENT SYSTEMS ON THE AREIA BRANCA FARM IN THE MUNICIPAL OF POMBAL- PB - BRAZIL (2011)

The burning of pasture and crop residues in the period prior to the rains in the semi-arid region is a practice usually applied by farmers to facilitate cleaning of the area and renew pasture. This study aimed to evaluate the effect of fire in chemical and biological soil properties in different areas in the hinterland of Paraíba. The treatments consisted in the use of fire and grazing in an area of growing with and no use of fire in grassland and preserved savanna area that served as a witness. Samples were collected bimonthly from September 2008 to July/2009. Samples were collected at depth of 0-20 cm in each area, for analysis of chemical indicators. To determine the biological indicators were installed traps "Provid" which consisted in the use of plastic bottles for collection of soil macrofauna, the soil samples without problems to determine the mesofauna were extracted using the type extractors modified Berlese-Tullgren (Oliveira 1999). Composed of rectangular boards, each containing structure, 25W lamps divided in two upper compartments contains rings with the samples and the lamps, while in the lower compartment are funnels and bottles of glass with a solution of ethyl alcohol 80% to the collection of organisms. The largest number of individuals of the mesofauna was collected in the areas of native grassland and savanna preserved without burning. As for the macrofauna, the capture of the organisms was higher in the area of native pasture without burning. The pH values were analyzed were near the neutrality, mainly suffering major reductions in CCQ. In burned areas (PNQ and CCQ) showed increased levels of P and K after burning and then there was a reduction in the levels.
The Origin of an Unexpected Increase in NH<sub>3</sub>–SCR Activity of Aged Cu-LTA Catalysts (2017)

We have recently reported an increase in low-temperature NH3–SCR activity of the copper-exchanged (Cu/Al = 0.50), high-silica (Si/Al = 23) LTA catalyst when it is hydrothermally aged at 1023–1173 K. Here we demonstrate that this unexpected phenomenon originates from the migration of Cu+ ions present inside the sod cages of Cu-LTA to the vacant single 6-rings which accompanies their oxidation to Cu2+ ions during (hydro)thermal aging. Hence, the sod cages, which are inaccessible to almost all reactant species so as to be regarded as useless for zeolite catalysis, were found to serve as a “catalyst reservoir” during the course of nitrogen oxides (NOx) reduction with NH3.
The Transjugular Intrahepatic Portosystemic Stent–Shunt Procedure for Refractory Ascites (1995)

Our findings in an uncontrolled prospective study suggest that the transjugular intrahepatic porto-systemic stent-shunt procedure was an effective treatment for many patients with liver cirrhosis and refractory ascites, but mortality from underlying diseases was substantial.
Antigenic phenotype and functional characterization of human tonsil B cells (1988)

Human tonsil cells were labeled with anti-leu-16, a monoclonal antibody (MoAb) that recognizes the CD20 antigen and that is specific for B cells. Two populations of B cells were identified by flow cytometry on the basis of antigen density. One labeled brightly with anti-Leu-16, and the other labeled at a level comparable to blood B cells. These two populations were characterized with a panel of MoAbs in two- and three- color flow cytometric studies and appeared to correspond to germinal- center and mantle-zone B cells. The pattern of staining of anti-Leu-16 on sections of frozen tonsil supported this characterization. Anti-Leu- 16 labeled germinal center cells more intensely than mantle zone cells and stained a few scattered B cells in the interfollicular zone. The ability of each Leu-16+ population to secrete IgG and IgM in response to mitogens was measured in a particle immunofluorescence assay. Dim Leu-16+ B cells (small, resting B cells and a subpopulation of preactivated cells) secreted IgG and IgM in response to pokeweed mitogen (PWM) but only IgG in response to B cell growth factor (BCGF). Bright Leu-16+ B cells (small to large activated cells and possibly memory cells) did not respond to PWM but secreted IgG in response to BCGF. The functional responses of dim Leu-16+ and bright Leu-16+ B cells were consistent with their identification as mantle-zone and germinal-center B cells. Phenotypic identification and functional studies of mantle-zone and germinal-center B cells may help clarify the differentiation pathway within the germinal center.
TeleWatt: An innovative electric vehicle charging infrastructure over public lighting systems (2013)

The growth of the Electric Vehicle (EV)'s market is strongly conditioned by the availability of cost-effective and reliable charging infrastructures. In the current state of the technology, the limited capacity of the batteries limits EV's market to urban moves. The rapid deployment of charging stations in urban areas is a real challenge. In this paper, we introduce an original approach consisting in reusing existing public lighting infrastructures for that purpose. Two main advantages characterize our solution. First, charging stations can be deployed rapidly without costly civil engineering. Second, a fraction of the power non consumed by the lamps at night can be used for the benefit of the charging stations. Meanwhile, such an approach must be achieved while guaranteeing the stability and quality of the lighting system.
Self-calibration of a camera using multiple images (2003)

The problem of calibrating cameras is extremely important in computer vision. Existing work is based on the use of a calibration pattern whose 3D model is known a priori. The authors present a complete method for calibrating a camera, which requires only point matches from image sequences. The authors show, using experiments with noisy data, that it is possible to calibrate a camera just by pointing it at the environment, selecting points of interests, and tracking them in the image while moving the camera with an unknown motion. The camera calibration is computed in two steps. In the first step the epipolar transformation is found via the estimation of the fundamental matrix. The second step of the computation uses the so-called Kruppa equations, which link the epipolar transformation to the intrinsic parameters. These equations are integrated in an iterative filtering scheme.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Improved Plasma Glucose Control, Whole-Body Glucose Utilization, and Lipid Profile on a Low-Glycemic Index Diet in Type 2 Diabetic Men (2004)

Only 4 weeks of an LGI diet was able to improve glycemic control, glucose utilization, some lipid profiles, and the capacity for fibrinolysis in type 2 diabetes. Even if changes in glycemic control were modest during the 4-week period, the use of an LGI diet in a longer-term manner might play an important role in the treatment and prevention of diabetes and related disorders.
Calibrated Decoders for Experimental Quantum Error Correction (2022)

Arbitrarily long quantum computations require quantum memories that can be repeatedly measured without being corrupted. Here, we preserve the state of a quantum memory, notably with the additional use of flagged error events. All error events were extracted using fast, midcircuit measurements and resets of the physical qubits. Among the error decoders we considered, we introduce a perfect matching decoder that was calibrated from measurements containing up to size-four correlated events. To compare the decoders, we used a partial postselection scheme shown to retain ten times more data than full postselection. We observed logical errors per round of 2.2±0.1×10^{-2} (decoded without postselection) and 5.1±0.7×10^{-4} (full postselection), which was less than the physical measurement error of 7×10^{-3} and therefore surpasses a pseudothreshold for repeated logical measurements.
Symposium: evaluating the reproducibility of pathological diagnosis using the 1997 Banff classification update (2006)

The purpose of this symposium was to evaluate the reproducibility of a histological diagnosis in renal allograft nephropathy according to the Banff classification. Seven transplant nephrologists and pathologists independently diagnosed the same glass slide specimens from 10 cases (five cases of acute rejection and five cases of chronic allograft nephropathy). Their diagnoses were collated and analyzed for the reproducibility of histological diagnosis. Consequently, several issues that hinder diagnostic reproducibility were identified.
Design and Build of a 1 Kilowatt Organic Rankine Cycle Power Generator (2013)

Organic Rankine Cycle (ORC) systems are capable of\nutilising low-enthalpy geothermal sources. The aim of the\nAbove Ground Geothermal and Allied Technologies\n(AGGAT) research programme is the development of ORC\nsystems within New Zealand. An experimental scale ORC\nsystem, known as ORC-B, was built at the University of\nCanterbury to assist with the research and development of\nthe system design and component selection process.\nThe unit is a 1 kW ORC consisting of four key components:\nevaporator, expander, condenser and pump. Selection of the\nworking fluid was found to be a constraining factor in the\ndesign. A refrigerant mix known as HFC-M1 was selected\ndue to its desirable performance, high safety and ease of\navailability in New Zealand. The heat source for the system\nis the exhaust of a Capstone gas turbine. Heat is transferred\nto the unit’s plate-type evaporator by a thermal oil\nextraction loop. Cooling is supplied to the plate-type\ncondenser from the available water supply. A scroll\nexpander is used to extract work from the system and the\nevaporator is fed by a high-pressure plunger pump. The\ninstrumentation selected allows measurement of the\nperformance of the system as well as PID control. The\nsystem has been designed and constructed and is now ready\nfor commissioning and testing.
Innovative signal processing and data analysis methods on JET for control in the perspective of next-step devices (2010)

In the last few years, it has been realized that more sophisticated control schemes are necessary to push the boundaries of tokamak operation and the performance of reactor-like machines. In addition, JET needs to operate safely with the new metallic wall and such protection will be needed for ITER. These objectives have motivated the development, benchmark and validation of new signal processing and data analysis methods. Two new approaches for the determination of the magnetic topology in real time have been validated on an extensive database of JET discharges, including advanced tokamak scenarios. Robust methods of confinement regime identification and disruption prediction are a prerequisite for safe, general control schemes. New identifiers have been developed and their success rates exceed 99% in determining whether plasmas are in the L or H mode. A new disruption predictor is being developed and has already provided success rates higher than 90% in realistic real-time conditions. Moreover, the generalization capability of this new predictor has been confirmed by applying it to new experimental campaigns not used for the training. The success rate remains high even more than ten campaigns, or about four years, after the last one used for the training. The deployment of video cameras in real time requires the development of new image processing algorithms, which have already been implemented and validated successfully on JET for the real-time identification of hot spots with a time resolution of tens of milliseconds. A series of new feedback schemes has also been explicitly developed not much to control the plasma but to really improve the physics understanding of some phenomena. Particularly interesting are the simultaneous control of the safety factor and pressure profiles and the real-time tracking of toroidal Alfven eigenmode instabilities. These advanced feedback schemes for physics understanding often require more advanced signal processing techniques like adaptive filtering, which have already been implemented. The paper concludes by discussing the use of these real-time analysis and control developments in next-step machines such as ITER.
Validity and reliability of the 6 minute walk in persons with fibromyalgia. (1999)

When using the 6MW it is necessary to conduct a practice walk, with the second walk taken as the baseline measure. It was determined from the correlations that the 6MW cannot replace the FIQ as a measure of function. The 6MW may be used as an indicator of aerobic fitness, although obtaining VO2 by means of a graded exercise test is preferable.
InAs/GaAs Quantum Dot Lasers on Silicon-on-Insulator Substrates by Metal-Stripe Wafer Bonding (2015)

InAs/GaAs quantum dot (QD) lasers on silicon-on-insulator substrates with Si rib structures are fabricated by metal-stripe wafer bonding, where the metal strips work not only as the bonding layer but also as electrodes. Our Fabry-Pérot lasers operate with a threshold current density of 520 A · cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> for the broad-area laser, and a threshold current of 110 mA for the ridge laser. The bonded lasers exhibit an InAs QD ground-state lasing at 1.3 μm at room temperature.
Decisive Criteria Between Stapedotomy and Cochlear Implantation in Patients with Far Advanced Otosclerosis (2014)

Although cochlear implantation gives better overall results, stapedotomy with hearing aids can still be very effective in the management of patients with far-advanced otosclerosis. It should therefore be proposed as a first-line treatment.
Consequences of Fetal Exposure to Maternal Diabetes in Offspring (2006)

Thus, fetal exposure to maternal diabetes may contribute to the worldwide diabetes epidemic. Public health interventions targeting high-risk populations should focus on long-term follow-up of subjects who have been exposed in utero to a diabetic environment and on a better glycemic control during pregnancy.
Sensitivity limits of coupled resonator optical waveguide (CROW) gyroscopes when subject to material losses (2015)

In recent years there has been a growing interest in optical microresonators as viable low cost on chip micro-optical gyroscopes with navigation grade sensitivities. Here, we analyze and compare the rotational sensitivity of coupled resonator optical waveguide (CROW) gyroscopes to equivalent single resonator gyroscopes under various geometric constraints and device parameters. We show that the CROW gyros offer a sensitivity enhancement over conventional single resonator gyros at low propagation losses. However, the single ring resonator gyro is found to be more stable over a wider range of propagation losses as well as boasting greater sensitivities for larger propagation losses compared to a CROW of the same size. Furthermore, an analysis of the maximum achievable sensitivity for different material technologies (Hydex, silicon oxynitride, and SOI) is conducted. While all materials achieved tactical grade sensitivities, Hydex shows the greatest potential for CROW gyros because of the stability of its sensitivity over a wide range of device parameters.
Premedication Strategy for Weekly Paclitaxel (2002)

Gas sensing based on ellipsometric measurement on porous silicon (2003)

Ellipsometry has sufficient sensitivity for sensor applications and is here used as an optical readout method in a gas sensing system. Porous silicon is used as sensing layers in which vapors of solvents can adsorb and condensate due to capillary effects. A miniaturized multi-beam ellipsometer system is proposed and the concept is demonstrated by measurements on alcohol vapors. Optimization of the sensor system is discussed and improvement of sensitivity and alteration of selectivity by metal deposition in porous silicon layers are presented.

Cetus - An Extensible Compiler Infrastructure for Source-to-Source Transformation (2003)

Cetus is a compiler infrastructure for the source-to-source transformation of programs. We created Cetus out of the need for a compiler research environment that facilitates the development of interprocedural analysis and parallelization techniques for C, C++, and Java programs. We will describe our rationale for creating a new compiler infrastructure and give an overview of the Cetus architecture. The design is intended to be extensible for multiple languages and will become more flexible as we incorporate feedback from any di#culties we encounter introducing other languages. We will characterize Cetus&apos; runtime behavior of parsing and IR generation in terms of execution time, memory usage, and parallel speedup of parsing, as well as motivate its usefulness through examples of projects that use Cetus. We will then compare these results with those of the Polaris Fortran translator.
Predicting hypoglycemia in diabetic patients using data mining techniques (2013)

The proper control of blood glucose levels in diabetic patients reduces serious complications. Yet tighter glycemic control increases the risk of developing hypoglycemia, a sudden drop in patients' blood glucose levels that causes coma and possibly death if proper action is not taken immediately. In this paper, we propose a hypoglycemia prediction model, using recent history of subcutaneous glucose measurements collected via Continuous Glucose Monitoring (CGM) sensors. The model is able to predict hypoglycemia events within a prediction horizon of thirty minutes accurately (sensitivity= 86.47%, specificity= 96.22, accuracy= 95.97%) using only the last two glucose measurements and the difference between them. More remarkably, this study shows the ability to develop a generalized prediction model suitable for predicting hypoglycemia events for the group of patients participating in the study.
