Microstructure, wear and corrosion performance of plasma electrolytic oxidation coatings formed on D16T Al alloy (2020)

Abstract The plasma electrolytic oxidation (PEO) coatings were produced on D16T Al alloy in the aluminate and silicate electrolyte with and without graphene. The phase composition, microstructure and elemental distribution of the coatings were tested by X‐ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X‐ray spectroscopy (EDX). The wear and corrosion resistance of PEO coatings were evaluated by dry sliding wear tests and electrochemical impedance spectroscopy (EIS). The morphology feature of the wear tracks was compared and analyzed by SEM and three‐dimensional microscope. The results demonstrate that the structure, wear and corrosion resistance of PEO coatings with graphene are better than that of PEO coatings without graphene. The coating fabricated in the aluminate electrolyte with graphene exhibited the lowest roughness. The coated samples formed in silicate electrolyte with graphene displayed the thickest, densest and the most compact coating. It exhibited the best wear and corrosion resistance due to the incorporation mode of graphene in the coatings. The mechanism of graphene improving the wear and corrosion resistance of PEO coating was further discussed. In summary, the comprehensive performances of PEO coatings formed in silicate electrolyte on D16T Al alloy are superior to that produced in aluminate electrolyte.
[Treatment of patients with chronic obstructive bronchitis]. (1995)

As shown in a trial in 172 patients with chronic obstructive bronchitis suffering from respiratory trouble, chronic cor pulmonale, circulatory insufficiency, combined application of electrical stimulation of the diaphragm with ultrasonic inhalations is much more effective than separate use of these two modalities which, when used together, potentiate positive and abate side effects of each other. The method is simple in application, reduces the duration of the hospital stay, prevents incapacitation.
Nitrogen‐15 nuclear magnetic resonance spectroscopy as a probe for the study of membrane models (1984)

Abstract 15 N NMR spectroscopy has been used to investigate liposomes from an enriched phospholipid (dipalmitoyl‐phosphatidylcholine). It is shown that this probe can yield interesting information on the dynamics of head groups and on some interactions at the lipid–water interface. Even large multilamellar vesicles give rise to narrow, symmetrical signals, with a maximum nuclear Overhauser effect over the phase transition temperature. The sensitivity of the technique as regards structural changes was demonstrated by a complete study made between 20 and 60°C.
Una aproximación al perfil de los estudiantes universitarios excelentes (2014)

&lt;p&gt;El objetivo de este trabajo era concretar el perfil de los alumnos excelentes en la universidad, de cara a precisar modelos eficaces de funcionamiento que se pudieran generalizar y enseñar, en la medida de lo posible. Para ello se recogieron datos de varios grupos de alumnos de 1º de la Universidad Politécnica de Valencia con las mejores notas de entrada de diferentes titulaciones cuyos resultados se compararon con los de alumnos de calificaciones medias. Fueron 281 estudiantes, 148 excelentes y 133 medios, elegidos como tales por las notas de la PAU, de 11 titulaciones de 9 centros de esta universidad.&lt;br /&gt;Se evaluaron las estrategias de aprendizaje, los enfoques y estilos de aprendizaje, las actitudes ante el aprendizaje y el auto-concepto de los estudiantes medios y excelentes de la muestra. Se analizó también la relación con el sexo y con el CI.&lt;br /&gt;Se llevó a cabo análisis de diferencias de las variables estudiadas y también un CATPCA. Los resultados de ambas pruebas mostraron una alta coherencia y nos permiten concretar un perfil de los estudiantes excelentes de la muestra que presentan mejores estrategias de aprendizaje que sus compañeros medios, con un claro enfoque profundo de aprendizaje predominante, que se asocia con mayor rendimiento académico, con preferencia por los estilos reflexivo y teórico de aprendizaje, con mejores actitudes ante el aprendizaje, con mejor auto-concepto académico, y con mejores calificaciones. Además, este perfil está más asociado con la mujer que con el hombre.&lt;/p&gt;&lt;p&gt;&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;
A fast table lookup based, statistical model driven non-uniform unit selection TTS (2013)

For multi-channel TTS applications, e.g. in a cloud service, it is highly desirable that high quality speech can be synthesized in low complexity. In this paper, we propose a fast table lookup based, statistical model driven approach to non-uniform unit selection TTS for that purpose. In TTS training, the voice font of all waveform segments is organized as a Gaussian kernel coded hash table and a table for storing quantized costs of all possible concatenation segment pairs. In synthesis, waveform segments with non-uniform lengths are first selected to construct a candidate lattice by looking up the Gaussian kernel coded hash table, and the best path is searched in the lattice by minimizing the accumulated concatenation scores, which are retrieved from the quantization table for possible concatenations. Experimental results show that the new approach can significantly reduce the search complexity while keep a high TTS voice quality.
The optimum dose of Puag-Haad in the treatment of taeniasis. (1989)

Forty-two per cent of 24 patients with Taeniasis saginata were cured by two-gram dose of a crude aqueous extract of the wood Artocarpus lakoocha, Puag-Haad, while eighty per cent of 25 patients were cured by three-gram dose which is comparable to the results of five-gram dose but had less side-effect. Thus, the three-gram dose of Puag-Haad is recommended in the treatment of taeniasis.
Towards stable high-speed metal-wire deposition, Part I: Parameter study (2012)

The thesis gives a number of solutions towards full automation of the promising manufacturing technology Robotized Laser Metal-wire Deposition (RLMwD). RLMwD offers great cost and weight saving potentials in the manufacturing industry. By metal deposition is here meant a layered manufacturing technique that builds fully-dense structures by melting metal wire into solidifying beads, which are deposited side by side and layer upon layer. A major challenge for this technique to be industrially implemented is to ensure process stability and repeatability. The deposition process has shown to be extremely sensitive to the wire position and orientation relative to the melt pool and the deposition direction. Careful tuning of the deposition tool and process parameters are therefore important in order to obtain a stable process and defect-free deposits. Due to its recent development, the technique is still manually controlled in industry, and hence the quality of the produced parts relies mainly on the skills of the operator. The scientific challenge is therefore to develop the wire based deposition process to a level where material integrity and good geometrical fit can be guaranteed in an automated and repeatable fashion. This thesis presents the development of a system for on-line monitoring and control of the deposition process. A complete deposition cell consisting of an industrial robot arm, a novel deposition tool, a data acquisition system, and an operator interface has been developed within the scope of this work. A system for visual feedback from the melt pool allows an operator to control the process from outside the welding room. A novel approach for automatic deposition of the process based on Iterative Learning Control is implemented. The controller has been evaluated through deposition experiments, resembling real industrial applications. The results show that the automatic controller increases the stability of the deposition process and also outperforms a manual operator. The results obtained in this work give novel solutions to the important puzzle towards full automation of the RLMwD process, and full exploitation of its potentials.
Operator Control Units for the Dismounted Soldier (2003)

As the army focuses on bringing fewer men to the forefront of the battle, robotic assets will become more prevalent. The soldier will need to be able to control these assets from a portable, rugged, and robust Operator Control Unit(OCU). It is important that the soldier's mobility and situational awareness not be adversely affected by this task. Although many of today's fielded systems are wearable or fit within a brief case, they still can cause a deterioration in the soldiers overall performance. A lightweight, non- intrusive solution is required with an interface that is easy to use, but robust enough to control multiple assets and their many functions. This paper will focus on the in-house development of an OCU for a lab-robot that parallels the OCU developed to support the Dismounted Mule operations that were a part of the Vetronics Technology Integration (VTI) effort in February, March, and April of 2003.
Microdomain contraction in microphase-separated multiblock copolymers (1993)

Linear multiblock copolymers, like their diblock analogs, undergo microphase separation and order into periodic morphologies when the blocks are sufficiently incompatible. To explore the conformations of such materials, four symmetric poly(styrene-b-isoprene${)}_{\mathit{n}}$ copolymers with 2n (1\ensuremath{\le}n=4) perfectly alternating blocks of nearly equal mass have been synthesized. Small-angle x-ray scattering reveals that the microdomain periodicity decreases with n along the lamellar normal, thereby confirming theoretical predictions and providing direct evidence for bridging among the 2(n-1) middle blocks.
Pathologic Interpretation of Transbronchial Biopsy for Acute Rejection of Lung Allograft Is Highly Variable (2011)

Despite the standardization of pathologic grading of acute rejection in transbronchial lung biopsies following lung transplantation, the reproducibility of pathologic diagnosis has not been adequately evaluated. To determine the interobserver variability for pathologic grading of acute rejection, 1566 biopsies from 845 subjects in the Lung Allograft Rejection Gene Expression Observational study were regraded by a pathology panel blinded to the original diagnosis and compared to the grade of acute rejection assigned by individual center pathologists. The study panel confirmed 49.1% of center pathologists' A0 grades, but upgraded 5.7% to A1 and 2.7% to grade ≥ A2 rejection; 42.5% were regraded as AX. Of 268 grade A1 samples, 21.2% were confirmed by the pathology panel; 18.7% were upgraded to ≥ A2 and 35.8% were downgraded to A0 with 24.3% being regraded as AX. Lastly, 53.5% of ≥ A2 cases were confirmed, but 15.7% were downgraded to grade A0 and 18.4% cases to A1, while 12.4% were regraded as AX. The kappa value for interobserver agreement was 0.183 (95%CI 0.147-0.220, p < 0.001). The results for B grade interpretation were similar. Suboptimal sampling is common and a high degree of variability exists in the pathologic interpretation of acute rejection in transbronchial biopsies.

CD47-targeted NIR-PIT increased direct cancer cell death and phagocytosis resulting in inhibited tumor growth and improved survival in a murine xenograft model of human bladder cancer.
Development of an electrochemical surface-enhanced Raman spectroscopy (EC-SERS) fabric-based plasmonic sensor for point-of-care diagnostics (2018)

Early disease diagnosis is crucial for timely and effective healthcare monitoring and treatment. Demand for modern point-of-care (POC) technologies has increased during the past decade. Continuous monitoring of patient health status can be achieved through wearable sensors which can be incorporated into clothing and other wearables. While electronic textiles that monitor physical parameters (heart rate, blood pressure, etc.) are increasingly commonplace, smart textiles capable of monitoring chemical biomarkers are much less common. In this work, a conductive plasmonic electrochemical sensor was developed from a cotton blend fabric modified with silver nanoparticles and conductive inks. para-Aminothiophenol (pATP) was used as an initial probe molecule to evaluate the performance of the fabric-based electrode for electrochemical surface-enhanced Raman spectroscopic (EC-SERS) measurements. Further investigation was then carried out to detect levofloxacin, a commonly prescribed antibiotic, in both 0.1 M NaF and synthetic urine as supporting electrolyte. It was found that the fabric-based electrode provided excellent EC-SERS signals, comparable to commercial screen-printed electrodes, allowing for rapid detection of levofloxacin at clinically relevant concentrations. To the best of our knowledge, this is the first time a fabric-based electrode has been reported for EC-SERS investigations, highlighting a promising platform for wearable point-of-care sensors.
Physics and detector simulation facility Type O workstation specifications (1990)

This document specifies the requirements for the front-end network of workstations of a distributed computing facility. This facility will be needed to perform the physics and detector simulations for the design of Superconducting Super Collider (SSC) detectors, and other computations in support of physics and detector needs. A detailed description of the computer simulation facility is given in the overall system specification document. This document provides revised subsystem specifications for the network of monitor-less Type 0 workstations. The requirements specified in this document supersede the requirements given. In Section 2 a brief functional description of the facility and its use are provided. The list of detailed specifications (vendor requirements) is given in Section 3 and the qualifying requirements (benchmarks) are described in Section 4.
Electro-Acoustic Stimulation (2009)

For simultaneous acoustic and electric stimulation to be perceived as complementary, it may be beneficial for hearing aids and cochlear implants (CI) to be adjusted to provide compatible pitch sensations. To this end, estimates of the pitch perceived for a set of acoustic and electric stimuli were obtained from 14 CI users who had usable low-frequency hearing, either in the non-implanted ear or in both ears. The subjects assigned numerical pitch estimates to each of 5 acoustic pure tones and 5 single-electrode electric pulse trains. On average, the acoustic frequency that corresponded in pitch to stimulation on the most apical electrode was approximately 480 Hz. This was about 1 octave lower than the frequency expected from Greenwood's frequency-place function applied to estimates of the electrode insertion angle based on X-ray images. Furthermore, evidence was found suggesting that pitch decreased with increasing duration of CI use. Pitch estimates from 5 subjects who completed the experiment before experiencing any other sounds through their CI were generally close to the values expected from a recently published frequency map for the cochlear spiral ganglion. Taken together, these findings suggest that some perceptual adaptation may occur that would compensate in part for the apparent mismatch between the intracochlear position of the electrodes and the acoustic frequencies assigned to them in the sound processor.
Charge-transfer processes in collisions of slowH+ions with hydrocarbon molecules:CH4,C2H2,C2H6,andC3H8 (2000)

Charge-transfer processes in collisions of ${\mathrm{H}}^{+}$ ions with ${\mathrm{CH}}_{4},$ ${\mathrm{C}}_{2}{\mathrm{H}}_{2},$ ${\mathrm{C}}_{2}{\mathrm{H}}_{6},$ and ${\mathrm{C}}_{3}{\mathrm{H}}_{8}$ molecules have been studied based on joint experimental and theoretical approaches in the collision energy from 0.2 to 4.0 keV. In the present experiment, the initial growth rate method was employed for determination of cross sections, while in the present theory, the molecular orbital expansion method was utilized for ${\mathrm{CH}}_{4}$ and ${\mathrm{C}}_{2}{\mathrm{H}}_{2}$ molecules. Both experimental and theoretical results indicate that if one assumes vibrationally excited molecular ions $({\mathrm{CH}}_{4}^{+},$ ${\mathrm{C}}_{2}{\mathrm{H}}_{2}^{+},$ ${\mathrm{C}}_{2}{\mathrm{H}}_{6}^{+},$ and ${\mathrm{C}}_{3}{\mathrm{H}}_{8}^{+})$ in the exit channel, then charge-transfer processes are sometimes found to become more favorable due to an accidental resonant condition. This is the clear indication of the role of vibrational excited states for charge transfer, and is found to be particularly so as the molecular size increases.

Effect of (-)-para-fluoro-deprenyl on survival and copulation in male rats. (1992)

Six-month old male rats were treated with 0.25 mg/kg, s.c., (-)p-fluoro-deprenyl (n = 40) or salt solution (n = 20) three times a week for 25 months. Three of the 20 saline-treated and 15 of the 40 drug-treated males survived (p = 0.05). Sexual activity of the survivors was tested at the end of the experiment. Three of the (-)p-fluoro-deprenyl-treated 31-month-old males proved to be sexually fully active, though, Wistar rats lose their ability to ejaculate by completing their second year of life. Non-copulator, 13 month old male rats were treated instead of the usually used 0.25 mg/kg dose with 0.01 mg/kg, s.c., (-)deprenyl (n = 9), (-)p-fluoro-deprenyl (n = 9) and salt solution (n = 9), three times a week, for 82 weeks and mating activity was tested weekly. The lifespan of the non-copulators was very short: 102 weeks for saline (n = 9), 106 weeks for (-)deprenyl (n = 8) and 104 weeks for (-)p-fluoro-deprenyl (n = 7). Survival was lightly changed by this very small dose treatment, one (-)deprenyl-treated male and two (-)p-fluoro-deprenyl-treated rats remained alive. The copulatory activity, however, was substantially improved.
Results of bone grafting of tibial defects in uncemented total knee replacements. (1988)

Bony defects of the articular surface are frequently encountered in total knee replacement. As an alternative to excising more tibia and using a thicker tibial component, autogenous bone grafts have been used to fill these defects. The authors have analysed 43 cases in which bone grafts were used in conjunction with an uncemented tibial component. The follow-up was 2 to 7 years. The results in these cases were compared with those in a similar group using uncemented components in which bone grafting was not required. There were 15 central grafts and 28 edge grafts. All the edge grafts and seven large central grafts were fixed with screws. If the graft size was more than 1 cm2, patients were not permitted to bear weight for 4 to 6 weeks. In the others, weight bearing was allowed immediately. All grafts united, most within 6 months, and substantial collapse was not observed. Notable sinking of the tibial component occurred in one late case, in which a rotatory subluxation developed due to patellar dislocation. Collapse of the graft in a recent case, however, suggests that when large grafts are used, a heavy central stem should be used on the tibial component.
SYNTHESIS AND ANTIMICROBIAL ACTIVITY OF SOME NEW PYRIDO[3′,2′:4,5]THIENO[3,2-d]- PYRIMIDINE DERIVATIVES (2004)

5-Acetyl-3-amino-4-aryl-6-methylthieno[2,3-b]pyridine-2-carboxamides (1a, b) were reacted with aromatic aldehydes or with some cycloalkanones to give the corresponding tetrahydropyridothienopyrimidinone derivatives 2a–f and 4a–d . The reaction of compound 1b with urea and/or carbon disulfide has been carried out and their products were identified. Some representative compounds were screened in vitro for their antimicrobial activities.
How reliable is a RAID? (2003)

Disk arrays offer greatly increased transfer bandwidth at low cost, but without additional data redundancy they can suffer from significantly degraded reliability. The authors examine the reliability of RAID (redundant arrays of inexpensive disks) systems and find that although extremely reliable disk arrays cannot be attained with data redundancy alone, RAID system reliability can be made better than conventional large disks with little extra hardware. They show that the rest of the system components, such as the host bus adapters, power supplies, and fans cannot be ignored. The authors present a scheme in which the system support components are organized into groups orthogonal to the data redundancy groups, thus guaranteeing that no single disk or component failure will permanently lose data. This approach yields disk arrays with reliability about 50% greater than conventional disk subsystems. If further reliability improvements are sought, various parts of the support hardware can be made redundant. The authors have shown how these affect the design of a 49-data-disk RAID.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
