Relationship between Nanostructure and Electrochemical/Biosensing Properties of MnO<sub>2</sub> Nanomaterials for H<sub>2</sub>O<sub>2</sub>/Choline (2008)

Manganese dioxides of different crystalline structures with different dimensionality (amorphous MnO2 nanoparticles, α-MnO2 nanoparticles, and β-MnO2 nanowires) were synthesized, characterized, and evaluated for their electrocatalytic activity to H2O2. Via a direct and facile electrochemical deposition method, MnO2 nanomaterials were codeposited onto glassy carbon (GC) electrodes with chitosan hydrogel. The catalytic oxidation current of amorphous MnO2 nanoparticles per unit mass to H2O2 is much larger than that of α-MnO2 nanoparticles and β-MnO2 nanowires; however, the catalytic oxidation current of amorphous MnO2 per unit surface area to H2O2 is the same as that of α-MnO2 nanoparticles and much less than that of one-dimensional β-MnO2 nanowires. The bicatalytic activity toward H2O2 of the electrodes modified with three different nanomaterials increases in the following order: amorphous MnO2 > α-MnO2 > β-MnO2. Further codeposition of chitosan hydrogel, choline oxidase (ChOx), and different MnO2 nanomaterials onto GC electrodes was applied to form choline biosensors. The biosensors modified with crystalline MnO2 respond to choline far more quickly than that modified with amorphous MnO2 in amperometric measurements. For the same concentration of choline, the response time is 8 s, 25 s, and 5 min for biosensors modified with β-MnO2, α-MnO2, and amorphous MnO2, respectively. The reasons for these phenomena were discussed in detail from the differences of the specific surface areas, the amounts of entrapped MnO2 on electrodes, crystalline structures, and dimensionality. The biosensors based on α-MnO2 nanoparticles and β-MnO2 nanowires were applied on amperometric detections of choline chloride with the linear ranges of 2.0 × 10−6−5.8 × 10−4 M and 1.0 × 10−6−7.9 × 10−4 M with the detection limits of 1.0 and 0.3 μM, respectively.
Weld Pool Impedance Identification for Size Measurement and Control (1983)

A primary indicator of weld quality is the size of the bead produced, and for full penetration welds this size parameter can be reduced to the width of the backbead. A method for determining this width in real-time is proposed that measures the natural frequency of pool motion when driven by a time varying arc plasma force. This method is developed analytically and verified experimentally for stationary weld pools. A control system based on this measurement scheme is also developed and simulation results are presented.

Head motion measurement and correction using<scp>FID</scp>navigators (2018)

Quantitative rigid-body motion information can be effectively estimated using the proposed FIDnav-based approach, which represents a practical method for retrospective motion compensation in less cooperative patient populations.
Effects of Oral Caffeine on Postdural Puncture Headache (1990)

Forty postpartum patients with postdural puncture headache (PDPH) were randomly assigned to receive oral caffeine (300 mg) or a placebo. Intensity of headache, quantitated using a visual analogue pain scale (VAS), was assessed immediately before drug administration and 4 and 24 h later. Relief of PDPH measured as delta VAS (initial VAS - VAS at 4 h) was significantly better in the caffeine than in the placebo group (P = 0.014). Six patients (30%) whose PDPH was relieved by caffeine at 4 h had recurrence of symptoms the following day. Our study demonstrates that caffeine administered orally provides relief, albeit if sometimes transient, from PDPH with minimal side effects.
Simulation of Polymer Foaming using the Lattice Boltzmann Method (2019)

This paper presents a 3D lattice Boltzmann model (LBM) for simulation of
polymer foaming processes. The model incorporates many of the essential aspects
of foaming phenomena: gas diffusion into nucleated bubbles, bubble dynamics and
coalescence, surface tension, the stabilizing disjoining pressure between
bubbles, and the non-Newtonian behavior of polymers. The model uses a free
surface approach to reduce the two-phase (liquid-gas) problem to a single-phase
liquid problem. The model is validated against the results of the Cell Model of
Arefmanesh and Advani, and then results are presented that demonstrate the
potential of the LBM model to predict various polymer foaming phenomena.
Bengal Women's Education League: Pressure Group and Professional Association (1984)

The first attempt to bring together all women interested in female education in Bengal was the convocation of a Bengal Women's Education Conference in February 1927 which led to the formation of the Bengal Women's Education League. The problems of female education had received considerable attention from social reformers in nineteenth-century Bengal, but the formation of the League signified that for the first time women were taking over the responsibility for leadership of the women's education movement. The All-India Women's Education conference had been held in January of the same year, 1927, indicating that the formation of the League in Bengal was part of a national trend of coordinated activity to improve educational opportunities for women.
Landlord Neutral 2030 (2021)

With the housing crisis continuing to punish renters, we call for the abolition of private landlordism.
Quantitative Measurement of Melanoma Spread in Sentinel Lymph Nodes and Survival (2014)

Cancer cell dissemination to the sentinel node is a quantitative risk factor for melanoma death. A model based on the combined quantitative effects of DCCD, tumor thickness, and ulceration predicted outcome best, particularly at longer follow-up. If these results are validated in an independent study, establishing quantitative immunocytology in histopathological laboratories may be useful clinically.
Direct imaging of the fragments produced during excimer laser ablation of YBa2Cu3O7−δ (1991)

The evolution dynamics of the fragments produced during KrF excimer laser (248 nm, 25 ns) ablation of YBa2Cu3O7−δ has been observed by ultrafast photography using a synchronized dye laser beam (∼1 ns) to probe above the target surface. The images show that fragment removal is initiated near the beginning of the laser pulse (≳10 ns), continues for a maximum of a few hundred nanoseconds, and has an expansion front velocity suggesting a target temperature varying from about 1500 to 4000 K or greater. The shock wave formed due to interaction of the ablated fragments with background oxygen gas has also been photographed, and its temporal evolution as a function of oxygen pressure has been shown to agree better with a planar than spherical model. The overall picture is that of an ablation process showing pronounced but understandable gas-dynamic effects.
Dynamic cluster resizing (2004)

Processor resources required for an effective execution of an application vary across different sections. We propose to take advantage of clustering to turn-off resources that do not contribute to improve performance. First, we present a simple hardware scheme to dynamically compute the energy consumed by each processor block and the energy-delay/sup 2/ product for a given interval of time. This scheme is used to compute the effectiveness of the current configuration in terms of energy-delay/sup 2/ and evaluate the benefits of increasing/decreasing the number of active issue queues. Performance evaluation shows an average energy-delay/sup 2/ product improvement of 18%, and up to 50% for some applications, in a quad-cluster architecture.
Extraction of Some Transportation Reference Planning Indices using High-Resolution Remotely Sensed Imagery (2002)

Recently, spatial information technologies using remotely sensed imagery and functionality of GIS (Geographic Information Systems) have been widely utilized to various types of transportation-related applications. In this study, extraction programs of some practical indices, to be effectively used in transportation reference planning problem, were designed and implemented as prototyped extensions in GIS development environment: traffic flow estimation (TFL/TFB), urban rural index (URI), and accessibility index (AI). In TFL/TFB, user can obtain quantitative results on traffic flow estimation at link/block using high-resolution satellite imagery. Whereas, URI extension provides urban-rural characteristics related to road system, being considered one of important factors in transportation planning. Lastly, AI extension helps to obtain accessibility index between nodes of road segments and surrounding district areas touched or intersected with the road network system, and it also provides useful information for transportation planning problems. This approach is regarded as one of RS-T (Remote Sensing in Transportation), and it is expected to expand as new application of remotely sensed imagery.
Overhead Line Parameters From Handbook Formulas And Computer Programs (1985)

Overhead line parameters can be calculated from handbook formulas, or with more general computer-oriented methods. At power frequency, the differences between the two approaches are usually negligible, but they can become large at higher frequencies. This paper discusses the causes of these differences for the engineer who wants to compare results from computer programs with those obtained from handbook formulas. It contains no new theories, but simply summarizes the experience gained in analyzing such differences over many years.
Azimuth‐dependent AVO in reservoirs containing non‐orthogonal fracture sets (2001)

Azimuthal anisotropy in rocks can result from the presence of one or more sets of partially aligned fractures with orientations determined by the stress history of the rock. The symmetry of a rock with horizontal bedding that contains two or more non‐orthogonal sets of vertical fractures may be approximated as monoclinic with a horizontal plane of mirror symmetry. For offsets that are small compared with the depth of the reflector, the azimuthal variation in P‐wave AVO gradient for such a medium varies with azimuth as where φ is the azimuth measured with respect to the fast polarization direction for a vertically polarized shear wave. φ 2 depends on both the normal compliance B N and the shear compliance B T of the fractures and may differ from zero if B N B T varies significantly between fracture sets. If B N B T is the same for all fractures, and the principal axes of the azimuthal variation in P‐wave AVO for fixed offset are determined by the polarization directions of a vertically propagating shear wave. At larger offsets, terms in and are required to describe the azimuthal variation in AVO accurately. φ 4 and φ 6 also depend on B N B T . For gas‐filled open fractures but a lower value of B N B T may result from the presence of a fluid with non‐zero bulk modulus.
Nearest Neighbor Influences on DNA Polymerase Insertion Fidelity (1989)

The kinetics of forming all possible single base substitution errors are measured for Drosophila melanogaster DNA polymerase alpha and avian myeloblastosis virus reverse transcriptase. Seventeen sites along bacteriophage M13 DNA are investigated so that effects of nearest neighbor base stacking on misinsertion kinetics can be evaluated. Polymerase alpha appears to be more error prone than reverse transcriptase. Polymerase alpha forms transversion mispairs at rates comparable to transition mispairs with two exceptions; A.A and C.C are formed with significantly higher and lower efficiencies, respectively. Reverse transcriptase forms transversions with lower efficiencies than transitions, especially low being A.G, G.G, and C.C. For both enzymes, misinsertion frequencies vary typically by 10-fold for the same mispair in different locations. Misinsertion frequency can be expressed as a product of two components, one based on Km and the other on Vmax. DNA polymerase alpha appears to use primarily Km discrimination (100-5000-fold) to achieve insertion fidelity while reverse transcriptase shows a greater balance between Km and Vmax discrimination. Nearest-neighbor base stacking interactions appear to have opposite effects on the two discrimination components. The 5'-nearest neighbor influence on Km is greater for correct insertions than for incorrect, while the influence on Vmax is greater for the incorrect base. Target sites that have pyrimidine as the 5'-nearest neighbor to incoming nucleotides show a higher than average misinsertion component based on Km, but a lower than average component based on Vmax. Conversely, target sites with nearest neighbor purines have a higher than average Vmax component. These results imply that nucleotide misinsertion "hot spots" will occur next to pyrimidines when Km discrimination is dominant and next to purines when Vmax discrimination is dominant. When Vmax and Km discrimination components have similar magnitudes, nearest neighbor effects tend to cancel thereby reducing the effects of base stacking on insertion error rates.
The simulation of front keyhole wall dynamics during laser welding (1997)

A physical model of keyhole support and propagation during high-translation-speed laser welding is described. A numerical code for the simulation of the front keyhole wall behaviour is developed on the basis of a `hydrodynamic' physical model assuming that: (i) only the front part of the keyhole wall is exposed to the high-intensity laser beam; and (ii) recoil pressure exceeds surface tension and propagation of the keyhole wall inside the sample is due to melt expulsion similar to that in laser drilling. The front keyhole wall profile, distribution of absorbed laser intensity and phase velocity of the solid/liquid (liquid/vapour) boundary are calculated for various processing parameters. The calculations show that, depending on the processing conditions, the absolute value of the keyhole wall velocity component parallel to the translation velocity vector can be higher than, smaller than or equal to the beam translation speed. When the component of the keyhole velocity vector parallel to the sample surface was higher than the beam translation speed, the formation of the humps on the keyhole wall was observed numerically.
Stem Cell Mobilizers Targeting Chemokine Receptor CXCR4: Renoprotective Application in Acute Kidney Injury (2015)

We have discovered a novel series of quinazoline-based CXCR4 antagonists. Of these, compound 19 mobilized CXCR4(+) cell types, including hematopoietic stem cells and endothelial progenitor cells, more efficiently than the marketed 1 (AMD3100) with subcutaneous administration at the same dose (6 mg/kg) in mice. This series of compounds thus provides a set of valuable tools to study diseases mediated by the CXCR4/SDF-1 axis, including myocardial infarction, ischemic stroke, and cancer metastasis. More importantly, treatment with compound 19 significantly lowered levels of blood urea nitrogen and serum creatinine in rats with renal ischemia-reperfusion injury, providing evidence for its therapeutic potential in preventing ischemic acute kidney injury. CXCR4 antagonists such as 19 might also be useful to increase circulating levels of adult stem cells, thereby exerting beneficial effects on damaged and/or inflamed tissues in diseases that currently are not treated by standard approaches.
Neue Entwicklungen und zukünftige Trends im nichtinvasiven Abstoßungsmonitoring nach Herztransplantation - Computerized Heart Allograft Recipient Monitoring (CHARM) (2002)

Computerized Heart Allograft Recipient Monitoring (CHARM) basiert auf der Analyse von intramyokardialen Elektrogrammen bei Patienten nach Herztransplantation. Mit Hilfe eines telemetriefähigen Herzschrittmachers können nichtinvasiv beliebig oft Sequenzen aufgezeichnet und analysiert werden. Die hohe Korrelation dieser Signale mit den klinischen Ergebnissen konnte bereits in einer monozentrischen Studie sehr gut dargestellt werden. Die Frage, ob dieses System auch bei unterschiedlichen therapeutischen Regimen anwendbar ist, sollte eine geblindete multizentrische Studie beantworten. An vier europäischen Zentren wurden hiefür während der Herztransplantation telemetriefähige Herzschrittmacher mit zwei epimyokardialen Schraubelektroden implantiert. Einminütige, schrittmacherstimulierte Signalsequenzen wurden in regelmäßigen Abständen postoperativ aufgezeichnet und über das Internet der automatischen Datenverarbeitung an einer zentralen Workstation zugeführt. Die für die Abstoßungsdiagnostik relevante Information befindet sich in der maximalen Steilheit des absteigenden Schenkels der T-Welle (VER-T-slew). Der geblindete Beobachtungszeitraum erstreckte sich über 6 Monate nach der Herztransplantation. Es wurde prospektiv ein "Single threshold diagnosis model" konzipiert, um die Fähigkeit von VER-T-slew zu verifizieren und Abstoßungen größer/gleich Grad 2 (Endomyokardbiopsien nach ISHLT-Klassifikation) zu erkennen. Die Endomyokardbiopsien (EMB) aller teilnehmenden Zentren wurden von einem Referenzpathologen geblindet nachbefundet. Bei 44 Patienten kamen 839 Untersuchungen und 366 EMBs zur Aufzeichnung. 37 Patienten waren am Ende des Beobachtungszeitraumes am Leben. Das Alter zum Zeitpunkt der Transplantation, die Verteilung der EMB-Grade und die Abstoßungsprävalenz unterschieden sich signifikant zwischen den Zentren. Die histologische Nachbefundung der EMB-Ergebnisse zeigte bemerkenswerte Unterschiede in der Klassifikation. Der Vergleich der mittleren VER-T-slew bei Patienten (n = 15), die sowohl Aufzeichnungen signifikanter Abstoßungen als auch abstoßungsfreie Episoden hatten, zeigte signifikant niedrigere VER-T-slew-Werte unter dem Einfluß der Abstoßungsepisode (97 ± 13 % versus 79 ± 15 %, p 0,0001). 20 der 25 Fälle mit signifikanten Abstoßungen wurden von VER-T-slew mit einer Schwelle unter 98 % richtig identifiziert (SENS 80 %, SPEC = 50 %, NPV = 97 %, PPV = 11 %, p 0,00005). Unter Einsatz des "Single threshold diagnosis model" hätten 48 % der EMBs ohne Nachteil für die Patienten eingespart werden können. In dieser prospektiven, geblindeten multizentrischen Studie konnte ein hoher NPV für die Erkennung von Fällen mit signifikanten Abstoßungen erzielt werden. Diese Methode ermöglicht eine sichere Reduktion der Zahl der EMBs und stellt somit eine nichtinvasive, kostengünstige und zukunftsweisende Variante zur sicheren Abstoßungsdiagnostik bei Patienten nach Herztransplantation dar.

Fast and Secure Linear Regression and Biometric Authentication with Security Update. (2015)

Abstract. We explicitly present a homomorphic encryption scheme with a flexible encoding of plain-texts. We prove its security under the LWE assumption, and innovatively show how the scheme can be used to handle computations over both binary strings and real numbers. In addition, using the scheme and its features, we build fast and secure systems of • linear regression using gradient descent, namely finding a reasonable linear relation between data items which remain encrypted. Compared to the best previous work over a simulated dataset of 108 records each with 20 features, our system dramatically reduces the server running time from about 8.75 hours (of the previous work) to only about 10 minutes. • biometric authentication, in which we show how to reduce ciphertext sizes by half and to do the computation at the server very fast, compared with the state-of-the-art. Moreover, as key rotation is a vital task in practice and is recommended by many authorized organi-zations for key management, • we show how to do key rotation over encrypted data, without any decryption involved, and yet homomorphic properties of ciphertexts remain unchanged. In addition, our method of doing key rotation handles keys of different security levels (e.g., 80- and 128-bit securities), so that the security of ciphertexts and keys in our scheme can be “updated”, namely can be changed into a higher security level.
