Improvement of response properties of MR-fluid actuator by torque feedback control (2002)

Magnetorheological (MR) fluids are substances that respond to an applied magnetic field with a change in their theological behavior. Though they are functionally similar to electrorheological (ER) fluids, MR fluids exhibit much higher yield strengths for the applied magnetic fields than ER fluids for the applied electric fields. The devices using MR fluids have an ability to provide high-torque, low-inertia, a safe device and simple interface. In this study, we report on an actuator developed using the MR fluid, which consists of an input part, an output part and an MR fluid clutch between them. First, the basic experiments are examined to investigate the characteristics of the actuator. Next, the torque control system of the MR-fluid actuator is proposed. Finally, the closed-loop control experiments were carried out and it is confirmed that the torque-feedback control is effective for improving the response properties of MR actuators.
Channel aware target tracking in multi-hop wireless sensor networks (2011)

A channel aware particle filtering approach is proposed for target tracking in multi-hop wireless sensor networks. The quantized M-bit data are relayed through multi-hop fading channels in order to reach a fusion center. Each relay node employs a binary decision relay scheme where the relay output is inferred from the channel impaired observation received from its source node. The observation likelihood function is derived based on the characteristic of the channel fading and noise. For two cases where the fusion center has the knowledge of the instantaneous fading channel gains and where it has only the knowledge of fading channel statistics, we propose the channel aware particle filtering for target tracking. The improved tracking accuracy and robustness to channel imperfection of the proposed filter is shown through computer simulations.
Anticancer Therapeutics That Target Selenoenzymes: Synthesis, Characterization, in vitro Cytotoxicity, and Thioredoxin Reductase Inhibition of a Series of Gold(I) Complexes Containing Hydrophilic Phosphine Ligands (2009)

Gold(I) complexes bearing water-soluble phosphine ligands, including 1,3,5-triaza-7-phosphaadamantane (PTA), 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane (DAPTA), and sodium triphenylphosphine trisulfonate (TPPTS), in combination with thionate ligands, were screened for their antiproliferative activities against human ovarian cancer cell lines A2780 either sensitive or resistant to cisplatin. In addition, the compounds were screened for their inhibition of mammalian thioredoxin reductases (TrxR), enzymes that are overexpressed in many tumor cells and contribute to drug resistance. The gold(I)-phosphine complexes efficiently inhibited cytosolic and mitochondrial TrxRs at concentrations that did not affect the related oxidoreductase glutathione reductase (GR). Additional complementary information on the enzyme metallation process and potential gold binding sites was obtained through the application of a specific biochemical assay using a thiol-tagging reagent, BIAM (biotin-conjugated iodoacetamide).
X-ray phase tomography of a moving object (2013)

We propose an algorithm for tomographic reconstruction of the refractive index map of an object translated across a fan-shaped X-ray beam. We adopt a forward image model valid under the non-paraxial condition, and use a unique mapping of the acquired projection images to reduce the computational cost. Even though the imaging setup affords only a limited angular coverage, our algorithm provides accurate refractive index values by employing the positivity and piecewise-smoothness constraints.
Application of a Bubble Column for Evaporative Cooling and a Simple Procedure for Determining the Latent Heat of Vaporization of Aqueous Salt Solutions (2009)

In this work we have studied the evaporative cooling effect produced in a continuous flow air bubble column, containing water and salt solutions. We have established that, at equilibrium, a significant reduction in temperature is produced in an insulated, continuous flow, bubble column. For example, with a continuous flow of inlet air at 22 degrees C, a water bubble column cools to about 8 degrees C, at steady state equilibrium. The cooling effect observed in a continuous bubble column of concentrated aqueous salt solution could be used for commercial applications, such as for evaporative cooling systems. We have developed a simple method, based on the steady state thermal energy balance developed in a bubble column, to determine the latent heat of vaporization of the liquid in the column. Only the equilibrium temperature of the bubble column, the temperature of the inlet gas and the hydrostatic pressure across the column need to be measured. This analysis has been used to determine the heat of vaporization for water and some concentrated salt solutions.

THE CASE FOR TOTAL KNEE REPLACEMENT IN UNICOMPARTMENTAL KNEE ARTHRITIS (1994)

In summary, unicompartmental replacement has narrow indications, involves more difficult surgical technique, and has inferior long-term results and revision complexity similar to that of tricompartmental replacement. It should be used by surgeons who are experienced with the technique and are performing a significant number of unicompartmental arthroplasties to justify its increased difficulty. Total knee replacement, on the other hand, is suitable for all gradations of knee disease, has a straightforward surgical technique, and has excellent long-term results. It is the treatment of choice for unicompartmental arthritis in the arthroplasty-indicated patient.

Formulation/cure technology for ultrahigh molecular weight silphenylene-siloxane polymers (1985)

Molecular weights above one million were achieved for methylvinylsilphenylene-siloxane terpolymers using a two-stage polymerization technique which was successfully scaled up to 200 grams. The resulting polymer was vulcanized by two different formulations and compared to an identically formulated commercial methylvinyl silicone on the basis of ultimate strength, Young's modulus, percent elongation at failure, and tear strength. Relative thermal/oxidative stabilities of the elastomers were assessed by gradient and isothermal thermogravimetric analyses performed in both air and nitrogen. The experimental elastomer exhibited enhanced thermal/oxidative stability and possed equivalent or superior mechanical properties. The effect of variations in prepolymer molecular weight on mechanical properties was also investigated.
Influence of low temperature ageing on optical and mechanical properties of transparent yittria stabilized-zirconia cranial prosthesis (2018)

Laser-based diagnostics and therapeutics show promise for many neurological disorders. However, the poor transparency of cranial bone limits the spatial resolution and interaction depth that can be achieved. We addressed this limitation previously, by introducing a novel cranial prosthesis made of a transparent nanocrystalline yttria-stabilized zirconia (nc-YSZ) which aims to enhance the diagnosis and treatment of neurological diseases by providing chronic optical access to the brain. By using optical coherence tomography, we have demonstrated the initial feasibility of ncYSZ implants for cortical imaging in an acute murine model. Although zirconia-based implants have been known for their excellent mechanical properties, the in vivo application was found to be affected by long-term failures, due to low temperature degradation. Accelerated aging simulations in humid environments at slightly elevated temperatures and over long periods typically transforms the ceramic surface into a monoclinic structure through a stress-corrosion-type mechanism. It was expected that the new nc-YSZ would show sufficient resistance to humid environments in comparison to the conventional zirconia implant. However, even a modest amount of transformation can change optical characteristics such as transparency. Herein we present the results of a simulated ageing study following the guidelines from the ISO 13356:2008 on aging of surgical zirconia ceramics. Comparison of %monoclinic transformation, optical transparency and mechanical hardness of nc-YSZ samples at baseline and following 25 and 100 h hydrothermal treatments shows our implant can withstand these extended ageing treatments.
Type III Acromioclavicular Joint Separation Associated with Late Brachial-Plexus Neurapraxia (1992)

We report the case of a 28-year-old woman who developed signs and symptoms of brachial-plexus neurapraxia eight years after a type III acromioclavicular (AC) joint separation. Stabilization of the AC joint resulted in resolution of the symptoms.
A Discussion of the Requirement of Patient Satisfaction of the Palliative and Hospice Care (2014)

Objectives: The objectives of this discussion were to analyze the symptoms that the terminal patients and the families most worry about, and to study the relationship between the medical team support and the need of the patients' families on the symptom management. This discussion also analyzed the relative critical factors and elements of the satisfaction of the palliative and hospice care. Material and Method: Subjects recruited were the families of the Hospice and Palliative Care patients who had died more than one month of a central Taiwan teaching hospital. Base on the purposive sampling from January, 2012 to October, 2012, use a questionnaire survey, FAMILY EVALUATION OF HOSPICE CARE, of the National Hospice and Palliative Care Organization (NHPCO). Out of 42 subjects, 33 completed the survey (78.57%). Results: The caregivers thought that the most in need of the terminal patients is the pain control, and secondly the physical care, and thirdly the breathing relief, and then supporting of the anxious mood. The caregivers score 9 at the sections of Patient Autonomy, Doctor-Patient Communication, and Good Ending. But the sections of Symptom Control and Mental support need to put more effort into. The relation between primary caregivers and patients made a big difference in the sections of Patient Autonomy and Good Ending. And the physical care made a difference in the section Patient Autonomy too (p≦0.05). The relation between primary caregivers and patients, and the quality of the hospital team physical care exert an influence of the satisfaction on the sections of Patient Autonomy and Good Ending. Conclusion: The patient's satisfaction depends on the care quality of the primary caregiver providing. The relation between the primary caregiver and the patient has an influence on the satisfaction and good ending.
CD19+IgM+ Cells from NOD Mice Demonstrate Enhanced Therapeutic Efficacy in Type 1 Diabetes Mellitus (2018)

We describe a protective effect on autoimmune diabetes and a reduced destructive insulitis in NOD.scid recipients following splenocyte injections from diabetic NOD donors and sorted CD19+ cells compared to NOD.scid recipients receiving splenocytes alone. This protective effect was age-specific (only CD19+ cells from young NOD donors exerted this effect; p &amp;lt; 0.001). Furthermore, we found that CD19+IgM+ cells is the primary cell subpopulation of B cells that delayed adoptive transfer of diabetes mediated by diabetogenic T cells from NOD mice (p = 0.002). In fact, removal of IgM+ cells from the CD19+ pool did not result in diabetes protection. Blockade of IL-10 with neutralizing antibodies at the time of CD19+ cell co-transfers also abrogated the therapeutic effect, suggesting that IL-10 secretion was an important component of the protective effect. These results were strengthened by ex vivo incubation of CD19+ cells with IL-5, which resulted in enhanced IL-10 production and significantly delayed diabetes progression compared to controls (p = 0.0005). To the best of our knowledge, this is the first study demonstrating that CD19+IgM+ cells is the primary cell subpopulation of regulatory B cells delaying diabetes mediated by diabetogenic T cells from NOD mice. The potential to expand CD19+IgM+ cells, especially in response to increased stimulation using IL-5 or by pharmacologic agents, may be a new therapeutic option for type 1 diabetes. Disclosure A.D.

Catalytic peptide assemblies (2018)

Self-assembly of molecules often results in new emerging properties. Even very short peptides can self-assemble into structures with a variety of physical and structural characteristics. Remarkably, many peptide assemblies show high catalytic activity in model reactions reaching efficiencies comparable to those found in natural enzymes by weight. In this review, we discuss different strategies used to rationally develop self-assembled peptide catalysts with natural and unnatural backbones as well as with metal-containing cofactors.
Van der Waals Materials for Atomically-Thin Photovoltaics: Promise and Outlook (2017)

Two-dimensional (2D) semiconductors provide a unique opportunity for optoelectronics due to their layered atomic structure and electronic and optical properties. To date, a majority of the application-oriented research in this field has been focused on field-effect electronics as well as photodetectors and light emitting diodes. Here we present a perspective on the use of 2D semiconductors for photovoltaic applications. We discuss photonic device designs that enable light trapping in nanometer-thickness absorber layers, and we also outline schemes for efficient carrier transport and collection. We further provide theoretical estimates of efficiency indicating that 2D semiconductors can indeed be competitive with and complementary to conventional photovoltaics, based on favorable energy bandgap, absorption, external radiative efficiency, along with recent experimental demonstrations. Photonic and electronic design of 2D semiconductor photovoltaics represents a new direction for realizing ultrathin, efficient solar cells with applications ranging from conventional power generation to portable and ultralight solar power.

List Ranking and Graph Algorithms on the Reconfigurable Multiple Bus Machine (1993)

The Reconfigurable Multiple Bus Machine (RMBM) is a model of parallel computation based on reconfigurable buses. We present constant time algorithms for list ranking, integer sorting and a number of fundamental graph problems on the RMBM. The algorithms are more efficient in terms of processors than the corresponding PARBS algorithms. The algorithms demonstrate some of the potential for computation available in the ability to manipulate communication paths as a vital part of computation.
BK Viremia Is Associated with Cyclophosphamide Use and Graft Versus Host Disease (GVHD) in Pediatric Hematopoietic Stem Cell Transplantation (SCT) (2012)

Overview: We describe preliminary results from the first comprehensive, prospective evaluation of SCT-TMA. To expand on the current literature, the goals are to determine clinical risk factors associated with the development of TMA and to report renal outcomes from this significant complication. Methods: Clinical and laboratory data are being collected on pediatric SCT recipients, beginning 3 weeks prior to conditioning and continuing for 100 days post-SCT. All pre-SCT patients are approached for recruitment and chronic dialysis is the only exclusion criterion. TMA is defined according to published clinical consensus guidelines as concomitant lactate dehydrogenase (LDH) above the upper limit of normal, platelet count and hemoglobin below the lower limit of normal or transfusion support, microangiopathic changes (schistocytes on peripheral blood smear), and low haptoglobin. All parameters must be noted for two consecutive measurements after day 0 to be considered positive.
Time is muscle in primary PCI: the strength of the evidence grows (2004)

This editorial refers to “Time-to-treatment significantly affects the extent of ST-segment resolution and myocardial blush in patients with acute myocardial infarction treated by primary angioplasty”1 by G. De Luca et al. on page 1009

In this issue of the European Heart Journal , De Luca et al., demonstrate that among 1072 patients with ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI), prolonged times between symptom onset and the first balloon inflation are associated with impaired ST-segment resolution, impaired myocardial blush grades, larger infarct sizes and higher mortality.1 These data add to a growing body of literature suggesting that renewed efforts are needed to reduce symptom-to-door and door-to-balloon times in order to improve myocardial perfusion, myocardial salvage and clinical outcomes among patients undergoing primary PCI for STEMI.1

While an association between prolonged door-to-balloon times and mortality has been described previously, the association of symptom-to-door and symptom-to-balloon times has not been as well established in its association with mortality.2 The demonstration of such an association may be hampered by survival bias: those patients with prolonged symptom-to-door times may not survive to be included in analyses such as the present one.2 It is noteworthy therefore that despite being enriched …

Pyroelectric organo-metallic langmuir-blodgett films (1989)

Abstract Organic materials are highly efficient non-linear media and can be prepared in a non-symmetric structure using the simple yet elegant deposition process termed the Langmuir-Blodgett technique. In this paper the pyroelectric behaviour of novel organo-metallic/behenic acid superlattices, prepared using this method, are reported. The largest pyroelectric coefficients (3 μCm−2K−1) were obtained from a ruthenium [(η5-cyclopentadienyl)-(bis-triphenylphosphine)] hexafluorophosphate complexed with a cyano (poly) phenyl liquid crystal. The influence of the phenyl rings and the effects of electron donating groups have been investigated to give an insight into the origins of the pyroelectric effect. The low dielectric loss and relative permittivity exhibited by these materials suggest a possible application as a thin film infra-red detector layer.

Small sample whole-genome amplification (2005)

Many challenges arise when trying to amplify and analyze human samples collected in the field due to limitations in sample quantity, and contamination of the starting material. Tests such as DNA fingerprinting and mitochondrial typing require a certain sample size and are carried out in large volume reactions; in cases where insufficient sample is present whole genome amplification (WGA) can be used. WGA allows very small quantities of DNA to be amplified in a way that enables subsequent DNA-based tests to be performed. A limiting step to WGA is sample preparation. To minimize the necessary sample size, we have developed two modifications of WGA: the first allows for an increase in amplified product from small, nanoscale, purified samples with the use of carrier DNA while the second is a single-step method for cleaning and amplifying samples all in one column. Conventional DNA cleanup involves binding the DNA to silica, washing away impurities, and then releasing the DNA for subsequent testing. We have eliminated losses associated with incomplete sample release, thereby decreasing the required amount of starting template for DNA testing. Both techniques address the limitations of sample size by providing ample copies of genomic samples. Carrier DNA, included in our WGA reactions, can be used when amplifying samples with the standard purification method, or can be used in conjunction with our single-step DNA purification technique to potentially further decrease the amount of starting sample necessary for future forensic DNA-based assays.
