Multirate analysis of haptic interaction stability with deformable objects (2003)

Describes a technique for allowing multiple users to haptically interact with a set of deformable slowly-simulated objects in a stable manner. Stability has been approached in the past by various researchers using passivity theory in order to avoid having to model the human operator closing the haptic loop. None of these solutions however can work well without the use of high update rates and thus break down in the case of haptic interaction with slowly simulated virtual environments such as the ones featuring highly precise deformable objects. This is particularly true for the case of surgical simulation with force feedback, where precision is a key issue and where complexity can reach high levels. The techniques presented in the paper are based on the concepts of a local model for haptic interaction adapted to deformable objects. Such approach allows multiple users to stably interact with a same object while feeling the influence of other users on the same object. Experimental results employing a PHANTOM haptic interface are proposed for a simple example.

Mixed noble metal–oxo clusters: platinum(iv)–gold(iii) oxoanion [PtIV2AuIII3O6((CH3)2AsO2)6]− (2023)

The first discrete mixed platinum(IV)-gold(III) oxoanion [Pt<sup>IV</sup><sub>2</sub>Au<sup>III</sup><sub>3</sub>O<sub>6</sub>((CH<sub>3</sub>)<sub>2</sub>AsO<sub>2</sub>)<sub>6</sub>]<sup>-</sup> (1) was synthesized by reaction of H<sub>2</sub>Pt(OH)<sub>6</sub> with H[AuCl<sub>4</sub>] in a simple one-pot procedure in aqueous solution at pH 7 and comprises two equivalent Pt<sup>IV</sup>O<sub>6</sub>(As(CH<sub>3</sub>)<sub>2</sub>)<sub>3</sub> units which are linked by three square-planar Au<sup>III</sup>O<sub>4</sub> units. Polyanion 1 could be isolated as a potassium or sodium salt in good yield, which were structurally characterized in the solid state by single-crystal XRD and TGA, and in solution by multinuclear (<sup>1</sup>H, <sup>13</sup>C, <sup>195</sup>Pt) NMR, indicating that polyanion 1 is stable in solution, which was confirmed by ESI-MS studies. The sodium salt of 1 undergoes a clean single-crystal-to-single-crystal (SCSC) structural transformation upon rehydration and dehydration.
Detection of human T‐cell leukemia/lymphoma virus type I in a transfusion recipient with chronic myelopathy (1989)

A white man with a progressive spastic paraparesis that began 15 months after sustaining severe trauma in a motor vehicle accident was positive for antibodies to human T-lymphotropic virus type I (HTLV-I) by enzyme-linked immunosorbent assay. Serum antibody to HTLV-I was confirmed by Western blot and radioimmunoprecipitation assay. We detected specific proviral DNA in peripheral blood lymphocytes by the polymerase chain reaction. Because the incidence of HTLV-I is generally restricted to Southern Japan and Caribbean black populations, the most likely source of HTLV-I infection in this patient was multiple intraoperative blood transfusions. The relatively short interval between transfusion and development of HTLV-I-associated myelopathy is consistent with the more rapid evolution of this clinical syndrome compared with adult T-cell leukemia.
Difference in Reaction Schemes in Photolysis of Triphenylsulfonium Salts between 248 nm and Dry/Wet 193 nm Resists (2008)

Chemically amplified (CA) resists are important in the semiconductor industry because of their high orders of magnitude of sensitivity enhancement. The key components of CA resists are a polymer with an acid labile group and a photoacid generator (PAG) that produces an acid upon exposure to radiation. Although the photolysis of PAGs has been intensively studied, the difference in reaction schemes between 248 and 193 nm resists had not been clarified. In this work, we have focused on the reaction of Ph2S•+, which is one of the major intermediates in the photolysis of triphenylsulfonium triflate. It was revealed that the difference in reaction schemes between 248 and 193 nm resists is caused by the ion molecular reactions of a polymer radical cation produced by electron transfer from the polymer to Ph2S•+.
Evaluation of a Genus- and Group-Specific Rapid PCR Assay Panel on Synovial Fluid for Diagnosis of Prosthetic Knee Infection (2015)

We evaluated a genus- and group-specific PCR assay panel using 284 prosthetic knee synovial fluid samples collected from patients presenting to our institution with implant failure. Using the Musculoskeletal Infection Society diagnostic criteria, 88 and 196 samples were classified as showing prosthetic joint infection (PJI) and aseptic failure (AF), respectively. Sensitivities of the synovial fluid PCR panel and culture were 55.6% and 76.1% (P ≤ 0.001), respectively, and specificities were 91.8% and 97.4% (P = 0.016), respectively. Among the 70 subjects who had received antibiotics within the month preceding synovial fluid aspiration (48 of whom had PJI), PCR panel and synovial fluid culture sensitivities were 64.5% and 85.4%, respectively (P < 0.0001). In this group, the PCR panel detected Staphylococcus aureus in two culture-negative PJI cases. Overall, the evaluated molecular diagnostic tool had low sensitivity when applied to synovial fluid.
A Gigaseal Obtained with a Self-Assembled Long-Lifetime Lipid Bilayer on a Single Polyelectrolyte Multilayer-Filled Nanopore (2010)

A lipid bilayer with gigaohm resistance was fabricated over a single 800 nm pore in a Si3N4 chip using 50 nm liposomes. The nanopore was prefilled with a polyelectrolyte multilayer (PEM) that triggered the spontaneous fusion of the lipid vesicles. Pore-forming peptide melittin was incorporated in the bilayer, and single channel activities were monitored for a period of 2.5 weeks. The long lifetime of the system enabled the observation of the time-dependent stabilization effect of the melittin open state upon bias application.
Analysis of Dual-Infeed HVDC With LCC–HVDC and VSC–HVDC (2012)

The impact of a voltage source converter-based HVDC (VSC-HVDC) infeed on a line-commutated converter-based HVDC infeed (LCC-HVDC) at the same busbar is investigated. Steady-state aspects such as the maximum available power (MAP) as well as transient aspects such as temporary overvoltage (TOV) and commutation failure immunity index are considered in the analysis. The results show that VSC-HVDC improves the maximum available power, reduces TOV, and makes the LCC-HVDC less susceptible to commutation failure. The resulting improvement in performance of the LCC-HVDC is quantified by a proposed “apparent increase in short circuit ratio” (AISCR) index. AISCR is a measure of the increase in short-circuit ratio for the LCC-HVDC that would be necessary in the absence of the VSC-HVDC link to obtain similar performance. The analytical results are validated by a detailed electromagnetic transient simulation.
Establishment of mechatronics engineering professional groups in Jordan (2012)

This paper describes the motivation and work performed to establish ways to link between academia and industry in Jordan, in the field of mechatronics engineering. Two efforts are described. First, the creation of an on-line forum, called the Jordan Mechatronics Network (JMN), for mechatronics professionals inside and outside of Jordan to share knowledge and facilitate cooperation, considering that many Jordanian engineers find employment in Arab Gulf states. This forum operates in the English language, is open, free, and user driven. This setup helps sustain JMN over time with minimal cost and overhead. The second effort is placed into the establishment of a society for mechatronics engineers in Jordan under the umbrella of the Jordan Engineers Association (JEA). The ongoing work currently finalizes the rules and regulations of the society, which is named Jordan Mechatronics Engineers Society (JMES). The JEA was established in 1958 and currently has over 81000 members. The JEA and JMES follow a traditional rigorous setup in the Arabic language with regulations for elections, membership, funding, investment, social and political activities, etc.
Spontaneous Emission from Planar Microstructures (1994)

Abstract The alteration of spontaneous emission characteristics in terms of the spontaneous lifetime and spectral emission characteristics are discussed for dipoles in the presence of nearby planar reflecting interfaces and cavities, specifically for the case of semiconductors. For dipoles closely spaced to absorbing metal mirrors, significant lifetime change is possible. Analysis and experimental data are presented for light emitting diodes. For dielectric Fabry-Perot microcavities, the expected lifetime change is small, but significant modification in the radiation pattern of the emitted light occurs. It is shown that the spectral characteristics of emission have a sensitive dependence on the dipole location in the cavity. Comparison is made between a classical against a quantum treatment of the spontaneous emission modification due to the cavity.
The Interaction of FRC and Ventilation on Occlusion Pressure in Conscious Man (1977)

Analytical and experimental results relating the interaction of functional residual capacity (FRC) and ventilation (V) on occlusion pressure in conscious man are presented. An analytical model was developed relating the airway pressure measured 100 ms after occlusion (P100) with FRC and V just before occlusion. By relating the change in diaphragmatic force with time during breathing to that during occlusion, it was found that P100 and IFRC could be linearly related. In order to test this model, 16 normal adult subjects with different FRC values (2.0 to 5.6 1) were studied during periods of increasing ventilation. Subjects increased V by rebreathing a mixture of 7% CO2 and 93% 02. Neither AP100/APC02 nor AV/APCO2 could be correlated to FRC since the differences in motoneuron activity in response to hypercapnia were probably greater than the variations in FRC. Linear regression analysis on all 16 subjects demonstrated a significant effect of FRC on the relationships P100 versus V, and AP100/APCO2 versus A V/APCO2. These experimental findings were in close agreement with analytical predictions and suggest that subjects with larger FRC values have a greater ventilation and ventilatory response for the same occlusion pressure and occlusion pressure response, respectively.
Advancing Research on the Complex Interrelations Between Atrial Fibrillation and Heart Failure (2020)

The interrelationships between atrial fibrillation (AF) and heart failure (HF) are complex and poorly understood, yet the number of patients with AF and HF continues to increase worldwide. Thus, there is a need for initiatives that prioritize research on the intersection between AF and HF. This article summarizes the proceedings of a virtual workshop convened by the US National Heart, Lung, and Blood Institute to identify important research opportunities in AF and HF. Key knowledge gaps were reviewed and research priorities were proposed for characterizing the pathophysiological overlap and deleterious interactions between AF and HF; preventing HF in people with AF; preventing AF in individuals with HF; and addressing symptom burden and health status outcomes in AF and HF. These research priorities will hopefully help inform, encourage, and stimulate innovative, cost-efficient, and transformative studies to enhance the outcomes of patients with AF and HF.

Electrical characterization of new and aged semiconducting glazes (2005)

This work presents the electrical characterization of antimony-doped semiconducting glazes before and after exposure to AC and DC electric fields under outdoor conditions and in the laboratory using the rotating-wheel-dip test (RWDT). Measurements of the I-V characteristics as well as dielectric spectroscopy in frequency domain (FDS) were performed on new and aged samples and results were compared. While I-V data only show a decrease in the current with aging, FDS data show more detailed features. Besides a decrease in DC conductance, a strong increase in low frequency dispersion (LFD) was found and a decrease in the relaxation polarization was indicated. The latter was more pronounced for samples aged under DC voltage. The observed relaxation polarization could originate from the presence of a low-conductive glassy surface layer on top of the "bulk" semiconducting glaze and it was weakened by the appearance of surface changes, including damage of the glassy surface layer, which thereby opened an alternative path for the current flow from the electrode to the "bulk" semiconducting glaze. The increase in LFD could be attributed to moisture trapped in the surface cracks formed during aging.
Transition metal containing decatungstosilicate dimer [M(H2O)2(γ-SiW10O35)2]10−(M = Mn2+, Co2+, Ni2+) (2006)

The new, monometal substituted silicotungstates [Mn(H(2)O)(2)(gamma-SiW(10)O(35))(2)](10-) (1), [Co(H(2)O)(2)(gamma-SiW(10)O(35))(2)](10-) (2) and [Ni(H(2)O)(2)(gamma-SiW(10)O(35))(2)](10-) (3) have been synthesized and isolated as the potassium salts K(10)[Mn(H(2)O)(2)(gamma-SiW(10)O(35))(2)] x 8.25 H(2)O (K-1), K(10)[Co(H(2)O0(2)(gamma-SiW(10)O(35))(2)] x 8.25 H(2)O (K-2) and K(10)[Ni(H(2)O)(2)(gamma-SiW(10)O(35))(2)] x 13.5 H(2)O (K-3), which have been characterized by IR spectroscopy, single crystal X-ray diffraction, elemental analysis and cyclic voltammetry. Polyanions 1-3 are composed of two (gamma-SiW(10)O(36)) units fused on one side via two W-O-W' bridges and on the other side by an octahedrally coordinated trans-MO(4)(OH(2))(2) transition metal fragment, resulting in a structure with C(2v) point group symmetry. Anions 1-3 were synthesized by reaction of the dilacunary precursor [gamma-SiW(10)O(36)](8-) with Mn(2+), Co(2+) and Ni(2+) ions, respectively, in 1 M KCl solution at pH 4.5. The electrochemical properties of 1-3 were studied by cyclic voltammetry and controlled potential coulometry in a pH 5 buffer medium. The waves associated with the W-centers are compared with each other and with those of the parent lacunary precursor [gamma-SiW(10)O(36)](8-) in the same medium. They appear to be dominated by the acid-base properties of the intermediate reduced species. A facile merging of the waves for 3 is observed while those for 1 and 2 remain split. Controlled potential coulometry of the single wave of 3 or the combined waves of 1 and 2 is accompanied by catalysis of the hydrogen evolution reaction. No redox activity was detected for the Ni(2+) center in 3, whereas the Co(2+) center in 2 shows a one-electron redox process. The two-electron, chemically reversible process of the Mn(2+) center in 1 is accompanied by a film deposition on the electrode surface.

Enhanced Oxidative Stress and Altered Antioxidants in Brains of Bcl‐2‐Deficient Mice (1998)

Bcl-2 is an antiapoptotic protein located in the outer mitochondrial membrane. Cellular perturbations associated with programmed cell death may be the consequence of disrupted mitochondrial function as well as excessive production of reactive oxygen species (ROS). Numerous studies indicate that Bcl-2 is involved in opposing cell death induced by oxidative stimuli, but its mode of action is uncertain. We reexamined the role of Bcl-2 by using a loss-of-function model, Bcl-2 knockout mice. Brains from Bcl-2-deficient mice had a 43% higher content of oxidized proteins and 27% lower number of cells in the cerebellum relative to wild-type mice. Incubation of cerebellar neurons from Bcl-2 +/+ brains with 0.5 mM dopamine caused 25% cell death, whereas in Bcl-2-deficient cells, it resulted in 52% death; glial cells provided protection in both cultures. Splenocytes from Bcl-2-deficient mice were also killed more effectively by dopamine as well as paraquat. Bcl-2-deficient mice did not survive intraperitoneal injection of MPTP, which caused a decrease in dopamine level in the striatum of Bcl-2 +/- brains, which was more significant than in wild-type mice. When compared with Bcl-2 +/+ brains, brains of 8-day-old Bcl-2-deficient mice had higher activities of the antioxidant enzymes GSH reductase (192%) and GSH transferase (142%), whereas at the age of 30 days, GSH peroxidase was significantly lower (66%). Activities of GSH transferase and GSH reductase increased significantly (158 and 262%, respectively) from day 8 to day 30 in Bcl-2 +/+ mice, whereas GSH peroxidase decreased (31%) significantly in Bcl-2 -/- animals. In summary, our results demonstrated enhanced oxidative stress and susceptibility to oxidants as well as altered levels of antioxidant enzymes in brains of Bcl-2-deficient mice. It is concluded that Bcl-2 affects cellular levels of ROS, which may be due to an effect either on their production or on antioxidant pathways.
Cell Lines and Transgenic Mice Expressing a Matrix Metalloproteinase-9 Promoter-Driven Reporter Gene: Potential for Assay of Ultraviolet Light Effects and Light-Inhibiting Compounds (2007)

Acute and chronic exposure to ultraviolet (UV) wavelengths in sunlight can cause adverse reactions in exposed areas of the skin and corneas. UV exposure up-regulates the synthesis of Matrix Metalloproteinses (MMPs) and evidence suggests these enzymes mediate tissue damage. Therefore MMP gene activity can serve as a surrogate marker for bioassays. In this study, we tested the possible utility for this purpose of two stably transfected cell lines (from mouse keratinocytes and rabbit epithelial-like corneal cells) and a transgenic mouse line (line 3445), each harboring a DNA construct containing a bacterial beta-galactosidase (LacZ) reporter gene driven by the rabbit MMP-9 transcriptional promoter. We observed only a weak 2-fold maximal induction of LacZ reporter gene expression in the mouse epidermal cell line after exposure to UV-B irradiation (5, 10, 40 mJ/cm2) and no significant expression of the reporter gene in the rabbit epithelial-like cell line. Similarly negative results were obtained when primary corneal epithelial cells from human and rabbit were exposed to different doses of UV-B irradiation and endogenous MMP-9 gene expression was assayed by zymography and immunoprecipitation analysis. In contrast, when skin from 3-day-old transgenic mouse line 3445 was exposed to UV-B and UV-A, a clear dose-dependent induction of the LacZ reporter gene occurred and the location of gene expression was dependent on the wave-length of irradiation. These results suggest that line 3445 transgenic mice may serve as a useful tool to quantitatively and qualitatively assess the biological effects of UV light and the efficacy of therapeutic agents.

Using a linear reflection phase gradient from pi/2 to pi/2 with pi10 step with unit cell index across face, the surface can steer a reflected beam to 20.2deg in thetas. The pattern of the electromagnetic field reflected with the normally incident y-polarized wave is analyzed and experimented.
A mixed strategy approach to Spanish prosody (1999)

Toshiba English Text-to-Speech Synthesizer utilizes several new techniques to produce synthesized speech that is more natural-sounding and intelligible than that created by conventional synthesizers. The closed-loop training method creates synthesis units that most closely resemble the training data and are the least susceptible to prosodic distortion noise by analytically solving an equation that minimizes distortion between target units and training data. The pitch contour model creates a codebook of representative word-based F0 contours by first clustering the training data using word stress and syllable numbers. Within each cluster, the training data is divided into different groups using lexical and phonological attributes of each word. In each group, a representative contour is created using approximate error estimation. The resulting approximate errors are used in offset level prediction for each contour. These techniques have significantly improved the prosodic quality, naturalness and intelligibility of the resulting synthesized speech.
Thin film deposition research and its impact on microelectronics scaling (2020)

Throughout his career, Dr. Stephen Rossnagel and his co-workers have had a profound influence on thin film deposition. His seminal work includes the development of reactive, collimated, and ionized methods of DC and RF magnetron sputtering, as well as plasma-enhanced atomic layer deposition. Most importantly, his contributions have been widely adopted within the microelectronics community in its efforts to produce finer layers with increased uniformity and functionality. While applications span a very broad range, from complementary metal oxide semiconductor device metallization to DNA sensing, Dr. Rossnagel has also conducted fundamental investigations into microstructural effects on electronic scattering. In this manuscript, the authors will highlight some of Steve’s contributions to these areas and their continued relevance to current and future microelectronic device scaling.
