Influence of Powders on Ionic Conductivity of Polycrystalline Zirconias (2003)

Grain boundary resistivity in zirconia systems can significantly affect total conductivity below 800°C, The influence of starting powders on the total conductivity is investigated for the 8 mol% yttria-stabilized zirconia polycrystals prepared from powders synthesized by three different methods and from two commercial powders. Conductivity measurements by AC impedance spectroscopy show a factor of two differences between the lowest and highest values because of the grain boundary resistivity. The contribution of grain boundary resistivity can be more than 10% at the temperatures less than 800°C. The total grain boundary resistivity is reduced drastically and the total conductivity can be improved by as much as 50% when the sintering temperature is increased or the powder particle size is reduced. Similar results are obtained for the higher conductivity electrolyte prepared from 9 mol% scandia-stabilized zirconia.
Osseous Adaptation and Range of Motion at the Glenohumeral Joint in Professional Baseball Pitchers (2002)

The throwing shoulder in pitchers frequently exhibits a paradox of glenohumeral joint motion, in which excessive external rotation is present at the expense of decreased internal rotation. The object of this study was to determine the role of humeral head retroversion in relation to increased glenohumeral external rotation. Glenohumeral joint range of motion and laxity along with humeral head and glenoid version of the dominant versus nondominant shoulders were studied in 25 professional pitchers and 25 nonthrowing subjects. Each subject underwent a computed tomography scan to determine bilateral humeral head and glenoid version. The throwing group demonstrated a significant increase in the dominant shoulder versus the nondominant shoulder in humeral head retroversion, glenoid retroversion, external rotation at 90 degrees, and external rotation in the scapular plane. Internal rotation was decreased in the dominant shoulder. Total range of motion, anterior glenohumeral laxity, and posterior glenohumeral laxity were found to be equal bilaterally. The nonthrowing group demonstrated no significant difference in humeral head retroversion, glenoid retroversion, external rotation at 90 degrees or external rotation in the scapular plane between shoulders, and no difference in internal rotation at 90 degrees, total motion, or laxity. A comparison of the dominant shoulders of the two groups indicated that both external rotation at 90 degrees and humeral head retroversion were significantly greater in the throwing group.
Mechanism of cellulose dissolution in the ionic liquid 1-n-butyl-3-methylimidazolium chloride: a 13C and 35/37Cl NMR relaxation study on model systems (2006)

13C and 35/37Cl NMR relaxation measurements on several model systems demonstrate that the solvation of cellulose by the ionic liquid (IL) 1-n-butyl-3-methylimidazolium chloride ([C4mim]Cl) involves hydrogen-bonding between the carbohydrate hydroxyl protons and the IL chloride ions in a 1 ratio 1 stoichiometry.

Fuzzy Logic Modeling & Control for Drilling Composite Laminates. (2001)

Abslracf In drilling of composite laminates, it is important to minimize or reduce wcmnces of delaminations. In particular, B peel-up delamination at entrance and poabdnt delamination at exit are common. Delaminations may be avoided by regulating the drill thrust force can be controlled by adjusting the feednte of tbe drill. Dynamics involved in drilling of composite laminates is time varying and nonlinear. lo this paper, a fopr logic model and conhml strategy are proposed. Simulation results show that the fuzzy model can deseribe the nonlinear time-varying proeess well. The fuzzy controller realizes a fast rise time and a tittle oversboot of drilling force.
Direct Printing of Graphene Electrodes for High-Performance Organic Inverters (2018)

Scalable fabrication of high-resolution electrodes and interconnects is necessary to enable advanced, high-performance, printed, and flexible electronics. Here, we demonstrate the direct printing of graphene patterns with feature widths from 300 μm to ∼310 nm by liquid-bridge-mediated nanotransfer molding. This solution-based technique enables residue-free printing of graphene patterns on a variety of substrates with surface energies between ∼43 and 73 mN m<sup>-1</sup>. Using printed graphene source and drain electrodes, high-performance organic field-effect transistors (OFETs) are fabricated with single-crystal rubrene (p-type) and fluorocarbon-substituted dicyanoperylene-3,4:9,10-bis(dicarboximide) (PDIF-CN<sub>2</sub>) (n-type) semiconductors. Measured mobilities range from 2.1 to 0.2 cm<sup>2</sup> V<sup>-1</sup> s<sup>-1</sup> for rubrene and from 0.6 to 0.1 cm<sup>2</sup> V<sup>-1</sup> s<sup>-1</sup> for PDIF-CN<sub>2</sub>. Complementary inverter circuits are fabricated from these single-crystal OFETs with gains as high as ∼50. Finally, these high-resolution graphene patterns are compatible with scalable processing, offering compelling opportunities for inexpensive printed electronics with increased performance and integration density.
Ultrasound Communication Through Thin Plates: Understanding and Estimating the Channel (2022)

As with all digital communications, understanding the propagation channel is essential. In this paper we present an analytical model of a channel consisting of a thin plate, including effects of frequency-dependent speed of sound and attenuation. We show how a compressed sensing approach can be used to estimate this channel impulse response from real measurements, even for cases when the plate thickness causes the reverberating pulses to overlap. The estimate can be seen as a sparsity constrained deconvolution of the combined impulse responses of the transmitting and receiving transducers. We then show with simulations that the proposed sparsity-constrained estimate is able to cope also in the presence of dispersion. We also analyze the performance of the proposed method both with simulations and experiments on 6 mm and 2 mm thick glass plate and 3 mm thick aluminum plate, and our results show that the model assumptions seems to hold.
Adaptive clocking with dynamic power gating for mitigating energy efficiency & performance impacts of fast voltage droop in a 22nm graphics execution core (2016)

Combining adaptive clocking with dynamic power gating in an optimal manner mitigates energy efficiency and performance impacts of fast supply voltage droop in a 22nm graphics execution core more effectively than adaptive clocking alone. Measurements show that there is an optimal V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MIN</sub> where the combination provides the best improvement - 14% lower energy at 890MHz vs. 4% with adaptive clocking.
Easy vs. Tricky (2013)

This short paper is a work-in-progress report on an experimental comparison and evaluation of users' performance in four line-tracing tasks based on two shapes and performed with three input methods (mouse, stylus, and touch-input). The shapes' properties used in the study created the two classes of shapes: easy and hard to replicate. As expected these two classes had different impact on user's performance in each task tested (tracing, lasso selection, steering through narrow and wide tunnel). The results show that participants replicating the shapes using touch-input were the least accurate but were the fastest in comparison to the remaining input methods. The stylus was the least error-prone method and the mouse was the slowest device in drawing tasks (tracing and selection). The differences in error distances between the input methods were less pronounced in steering tasks but timing data showed that mouse was still the slowest one. While the time of replication did not differ between the two shapes tested, the differences between the errors participants made were significant for all tasks and input devices, and patterns of these differences were consistent between the shapes. These results confirm predictions from a previous study and show which shapes' properties can make their replication more difficult. The results can be used to design shapes that are easy to replicate, e.g., in surface-based gestural interaction.
Miscibility, Structure, and Property of Poly(biphenyl dianhydride perfluoromethylbenzidine)—Poly(ether imide) Molecular Composites (1996)

Miscibility of segmented rigid-rod polyimide (PI), viz., biphenyl dianhydride perfluoromethylbenzidine (BPDA-PFMB), and flexible polyether imide (PEI) molecular composites was established by differential scanning calorimetry. The composite films of BPDA-PFMB/PEI were drawn at elevated temperatures above their glass transitions. Tensile moduli of the films were evaluated as a function of composition and draw ratio. Molecular orientations of polyimide were determined by birefringence and wide-angle X-ray diffraction. The crystal orientation behavior of the 80/20 BPDA-PFMB/PEI was analyzed in the framework of the affine deformation model.
Autologous Transfusion Device for Use in Resource-Limited Settings (2011)

The lack of donated blood available for emergency transfusions in the developing world is a critically important issue that can significantly affect the prognosis and recovery of hemorrhaging patients. Autologous transfusion, in which a patient receives a transfusion of his or her own blood, is often used to reduce the need for donated blood. Clinicians in resource-limited settings have developed an improvised method of performing autologous transfusion using a soup ladle and simple gauze filter. This procedure is commonly used in cases of ruptured ectopic pregnancy, during which patients can lose up to 2 l of blood through internal hemorrhage. The process involves several labor- and material-intensive steps, which can cause complications due to excessive environmental exposure and handling of the blood. The aim of this research was to develop a low-cost blood salvage device applicable to resource-limited settings capable of replacing the current method.
Field emission study of titanium silicide array (2004)

Abstract A silicon field emitter array (FEA) was fabricated on n‐type, low‐resistance (5Ω·cm) Si(100) wafer by anisotropic etching (dipping in 40 wt.% KOH solutions). To increase the thermochemical durability of the tip, the long‐term stability and the current density, Ti (30 nm) film was deposited with evaporation and the silicide was formed by annealing at 650°C. The C 54 –TiSi 2 phase of the sample was observed by x‐ray diffraction analysis. The emission characteristics of the titanium silicide FEA were compared with those of an Si FEA under high vacuum conditions of ∼10 −7 Torr. The turn‐on voltage of the titanium silicide FEA is ∼1500 V whereas that of the Si FEA is found to be 1950 V. In addition, the emission stability of the titanium silicide FEA proved to be much better than that of the Si FEA. Copyright © 2004 John Wiley &amp; Sons, Ltd.

Molecularly imprinted polymers as selective recognition elements for optical sensors based on fluorescent measurements (2004)

Molecularly imprinted polymers have been applied to the development of piezoelectric and electrochemical sensors and in radioactive competitive assays. However, its application to optical sensors is still limited due to the lack of appropriate fluorescent molecules able to compete with the template by the specific binding sites in the polymer. Optimisation of the polymer composition to get the maximum specific binding in the least time is another aim of research in this area. In this paper we present several approaches to address these issues namely the application of a experimental design for MIP optimization and the design and synthesis of novel fluorophores for the analysis of beta-lactam antibiotics using competitive assays or labeled MIPs.

Early failure of acetabular components inserted without cement after previous pelvic irradiation. (1995)

The effect of previous irradiation of the pelvis on the survival of acetabular components inserted without cement in primary total hip arthroplasty was examined. We searched a database of 1319 patients who had been managed with a primary total hip arthroplasty with insertion of a hemispherical porous-coated acetabular component without cement. This revealed twelve hips in eleven patients who had been managed with previous irradiation of the pelvis. Three patients had died after less than one year of follow-up, leaving eight patients with nine acetabular components available for study at an average of thirty-seven months (range, seventeen to seventy-eight months) after the operation. The type of radiation as well as the fractionation, dose, and portals were reviewed to determine the exposure of the periacetabular region to radiation. Failure of the component was assessed radiographically and clinically. At the time of follow-up, three of the nine acetabular components had migrated, as seen on radiographs, and had been associated with progressive radiolucency without clinical symptoms. Thus, four of the nine acetabular components failed, at an average of twenty-five months (range, sixteen to thirty-eight months). The other five components had not failed clinically and were stable radiographically at an average of thirty-six months (range, seventeen to sixty-three months). The insertion of acetabular components without cement in a previously irradiated pelvis has a high rate of failure. However, a superior method of acetabular reconstruction in this difficult situation has yet to emerge.
Potential Serological Use of a Recombinant Protein That Is a Replica of aMycobacterium tuberculosisProtein Found in the Urine of Infected Mice (2004)

The recent availability of numerous well-characterized Mycobacterium tuberculosis recombinant proteins has revived interest in the serological diagnosis of tuberculosis. Several promising results have been reported, particularly when more than one antigen is used in the test. However, thus far these antigens have not been used in routine diagnostic tests because they lack sufficient sensitivity. In addition, with the exception of one antigen, most recombinant M. tuberculosis proteins do not identify the majority of tuberculosis patients coinfected with human immunodeficiency virus (HIV). Here, we report a newer M. tuberculosis protein that is a promising candidate for increasing the sensitivity of the serological tests, in particular for patients coinfected with HIV. The protein was found in the urine of mice during the early stages of infection with M. tuberculosis (10 to 14 days), thus suggesting that the antigen is abundantly released during the in vivo growth of the mycobacterium. Reverse genetics was used to produce the recombinant protein, which we named U1 (for urine protein 1). Using a conventional enzyme-linked immunosorbent assay (ELISA), antibody to U1 could be detected in 60% of patients with pulmonary tuberculosis with no signs of coinfection with HIV (n = 83). Conversely, anti-U1 antibody was detected in 87% of the sera from tuberculosis patients coinfected with HIV (n = 47). Out of 12 HIV-infected nontuberculosis patients' sera, 9 did not react with U1 and three sera gave borderline ELISA signals (signal/cutoff of < or =1.75). These results suggest that the high efficiency of U1 in identifying tuberculosis patients coinfected with HIV may be related to abundant release of this protein during the initial phase of the HIV coinfection. The immediate availability of the antigen at a time point in which the patient's immune system is still competent would lead to a secondary immune response to U1 that persists for months in the patient's serum.
<p>Systematic review of sequencing of ALK inhibitors in <em>ALK</em>-positive non-small-cell lung cancer</p> (2019)

The objective of this study was to understand outcomes of patients treated with ALK inhibitors, especially when ALK inhibitors are followed by other ALK inhibitors. A systematic literature review was conducted in PubMed, Embase, and Cochrane through July 17, 2017. Conference abstracts (three meetings in past 2 years) also were searched. Of 504 unique publications, 80 met inclusion criteria (47 clinical trials, 33 observational studies). Observational studies have the potential to provide information for ALK inhibitors used sequentially. Ten observational studies reported median overall survival of crizotinib-led sequences ranging from 30.3 to 63.75 months from initiation of crizotinib; 49.4-89.6 months from metastatic non-small-cell lung cancer diagnosis; and 15.5-22.0 months from initiation of the second-generation ALK inhibitor after initial crizotinib. Sequencing of ALK inhibitors may benefit patients progressing on initial ALK inhibitors.
A FBD theory based grid frequency independent current reference generation method for a three phase inverter interfacing renewable energy sources to generalized micro-grid (2011)

In this paper, inverter reference current generation using position sampled FBD method for a three inverter interfacing the renewable energy source to the generalized micro-grid is proposed. The proposed method facilitates high bandwidth grid active power flow control along with grid current THD control facility by finding suitable current references directly in the a-b-c frame. The proposed method is less computational intensive than the conventional p-q theory based methods because of the absence of phase lock loop (PLL), Park's transformation requirements and positive and negative sequence grid voltages extraction. The proposed method is also independent of grid voltage fundamental frequency and capable of rejecting the grid voltage harmonics. The proposed method is validated with experimental study and test results presented depict the efficacy of the proposed system.
Conformation‐based design of two cyclic physalaemin analogues (1991)

Two new cyclic analogues of physalaemin were designed on the basis of the conformation found in DMSO solution. Glp-Ala-cyclo(-Asp-Pro-Asn-Lys-)-Phe-Tyr-Gly-Leu-Met-NH2 (1) was synthesized by cyclization of physalaemin. In 2 the Asp residue was replaced by Glu. The linear analogue of 2 was synthesized by the solid phase method and subsequently cyclized. Two-dimensional nmr methods were employed to assign the proton and carbon resonances. Proton-proton distances were extracted from rotating frame nuclear Overhauser effect spectra and used as restraints in the molecular dynamics calculations. Analogue 1 was found to have a similar conformation as physalaemin, whereas 2 did not form intramolecular hydrogen bonds. The pharmacological evaluation revealed that both peptides have similar potencies as physalaemin in the dog carotid artery (NK-1 receptor). Therefore, the charged side chains of physalaemin appear not essential for NK-1 activation. However, the other tachykinin receptors show good sensitivity to the cyclic peptides. It is concluded that the replacement of a salt bridge by an amide bond connecting the side chains of natural residues might provide useful information about the biological significance of some charged side chains of neurokinins.

Transactional Execution of Java Programs (2005)

Parallel programming is difficult due to the complexity of dealing with conventional lock-based synchronization. To simplify parallel programming, there have been a number of proposals to support transactions directly in hardware and eliminate locks completely. Although hardware support for transactions has the potential to completely change the way parallel programs are written, initially transactions will be used to execute existing parallel programs. In this paper we investigate the implications of using transactions to execute existing parallel Java programs. Our results show that transactions can be used to support all aspects of Java multithreaded programs. Moreover, the conversion of a lock-based application into transactions is largely straightforward. The performance that these converted applications achieve is equal to or sometimes better than the original lock-based implementation.
