A 60&#x2013;110 GHz low conversion loss tripler in 0.15-&#x00B5;m MHEMT process (2009)

A 60-110 GHz low conversion loss tripler in a 0.15-μm InGaAs metamorphic high electron-mobility transistor (MHEMT) technology is presented in this paper. The tripler employs a configuration of an anti-parallel diode pair to produce the third harmonic signal. Between 60 and 110 GHz, this tripler features a conversion loss of less than 20 dB with an input power of 15 dBm. The minimum conversion loss is 13 dB at 81 GHz with an output power of 3 dBm. The output 1-dB compression point (P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1dB</sub> ) is higher than 3 dBm among the operating bandwidth. The output power is higher than 4 dBm while the driving power is 20 dBm. The overall chip size is 1×1 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . To the best of the author's knowledge, this is the highest output power MMIC-based diode tripler to cover the entire E- and W-band without dc power consumption.
Process-oriented Guided Inquiry Learning in Engineering (2012)

Abstract Process-oriented guided inquiry learning (POGIL) is a student-centered pedagogy. While it has been extensively used in the chemistry curriculum, its use in engineering has been limited. This paper describes the use of POGIL in the Introduction to Materials Engineering course. Assessment of its effectiveness shows that details of implementation can play a critical role. In particular, because of the student-centered aspect of the approach students can feel that they are not being “taught” and thus not take ownership of their own learning. By providing opportunities for students to check their understanding and reflect on their learning process performance is enhanced over a traditional lecture course.
Size- and density-dependent acoustic differential bioassembly of spatially-defined heterocellular architecture (2022)

Emerging acoustic bioassembly represents an attractive strategy to build cellular closely-packed organotypic constructs in a tunable manner for biofabrication. However, simultaneously assemble heterogeneous cell types into heterocellular functional units with spatially-defined cell arrangements, such as complementary and sandwich cytoarchitectures, remains a long-lasting challenge. To overcome this challenge, herein we present an acoustic differential bioassembly technique to assemble different cell types at the distinct positions of the acoustic field based on their inherent physical characteristics including cellular size and buoyant density. Specifically, different cell types can be differentially assembled beneath the nodal or the antinode regions of the Faraday wave to form complementary cytoarchitectures, or be selectively positioned at the center or edge area beneath either the nodal or the antinode regions to form sandwich cytoarchitectures. Using this technique, we assemble human induced pluripotent stem cell-derived liver spheroids and endothelial cells into hexagonal cytoarchitectures<i>in vitro</i>to mimic the cord and sinusoid structures in the hepatic lobules. This hepatic lobule model reconstitutes liver metabolic and synthetic functions, such as albumin secretion and urea production. Overall, the acoustic differential bioassembly technique facilitates the construction of human relevant<i>in vitro</i>organotypic models with spatially-defined heterocellular architectures, and can potentially find wide applications in tissue engineering and regenerative medicine.

Studies of regenerative braking in electric vehicle (2010)

Generally the braking system for a car is based on hydraulic braking technology. However, this traditional braking methodology causes a lot of energy wastage since it produces unwanted heat during braking. Thus, the invention of regenerative braking in electric car has overcome these disadvantages moreover it helps in save energy and provides higher efficiency for a car. In regenerative mode, the motor act as a generator, it transfers the kinetic to electrical energy to restore the batteries or capacitors. Meanwhile, the brake controller monitors the speed of the wheels and calculates the torque required plus the excessive energy from the rotational force that can be converted into electricity and fed back into the batteries during regenerative mode. The merits of regenerative braking over traditional braking are energy conservation, wear reduction, fuel consumption and more efficient in braking. Nowadays, the brilliant technology in automotive industry towards regenerative braking is improving. By using a flywheel and ultracapacitor with DC-DC converter it had enhance the regenerative performance. In this paper, the working principle and braking controller for the regenerative braking have been studied to promote the efficiency and realization of energy saving in the electric vehicle.

RAFT‐mediated graft polymerization of glycidyl methacrylate in emulsion from polyethylene/polypropylene initiated with γ‐radiation (2017)

ABSTRACT The successful reversible addition‐fragmentation (RAFT)‐mediated graft polymerization of glycidyl methacrylate (GMA) in emulsion phase from polyethylene/polypropylene nonwoven fabric using 4‐cyano‐4‐[(phenylcarbonothioyl)thio]pentanoic acid under γ‐irradiation at ambient condition is reported. While conventional graft polymerization in emulsion phase yielded grafted materials with low of grafting (Dg) values [&lt;7.5% at 10% (wt/wt) GMA], addition of RAFT agent to the graft polymerization system allowed the synthesis of polyethylene/polypropylene‐ g ‐poly(GMA) with more tunable Dg (8% ≤ Dg ≤ 94%) by controlling the grafting parameters. Relatively good control (PDI ∼1.2 for selected grafting conditions) during polymerization was attained at 100:1 monomer‐to‐RAFT agent molar ratio. The number average molecular weight of free poly(glycidyl methacrylate) (PGMA) increased as a function of monomer conversion. NMR analyses of the free PGMA homopolymers indicate the presence of dithiobenzoate group from 4‐cyano‐4‐((phenylcarbonothioyl)thio) pentanoic acid on the polymer chain. The reactive pendant oxirane group of the grafted GMA can be modified for various environmental and industrial applications. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017 , 134 , 45270.

Further observations on an insecticide-bait-box method for the control of sylvatic plague vectors; effect of prolonged field exposure to DDT powder (1960)

A field experiment was conducted from July 1958 to February 1959 in the San Francisco Bay region to test the effect on flea populations of prolonged exposure of the native meadow vole, Microtus californicus , to 5% DDT powder in insecticide-bait-boxes. Previous studies had shown that two important vectors of sylvatic plague, Malaraeus telchinum and Hystrichopsylla linsdalei , could be controlled both on their hosts and in the host nests by this method. However, the question of possible resistance was postulated since the control of H. linsdalei on its host was inferior to control of other flea species. Bait-boxes with DDT powder were maintained in the field for 6 months. Records of flea populations on Microtus during this period showed equally good control of all flea species. Observations on vole nests at termination of the study revealed deposits of DDT and good control of all flea species in them. During the period of study, the evidence suggested that none of the flea species involved exhibited DDT resistance. The major portion of the field routine was done by Messrs A. R. Kinney and R. L. Martin. Flea identifications were made by Mr H. E. Stark. Analyses of nests and rodents for DDT were performed by Mr C. Cueto, Technical Development Laboratories, CDC, Savannah, Georgia.
Flow Analysis of Field-Controllable, Electro- and Magneto-Rheological Fluids Using Herschel-Bulkley Model (1999)

The Bingham plastic constitutive model has been widely used to predict the post-yield behavior of electro- and magneto-rheological fluids (ER and MR fluids). However, if these fluids experience shear thinning or shear thickening, the Bingham plastic model may not be an accurate predictor of behavior, since the post-yield plastic viscosity is assumed to be constant. In a recent study, it was theoretically and experimentally demonstrated that the Herschel-Bulkley fluid model can be successfully employed when evaluating non-Newtonian post-yield behavior of ER and MR fluids. In this paper, we extend our previous work and adopt the Herschel-Bulkley model to include a detailed analysis of ER and MR fluid dynamics through pipes and parallel plates. Simplified explicit expressions for the exact formulation are also developed. It is shown that the proposed simplified model of the Herschel-Bulkley steady flow equations for pipes and parallel plates can be used as an accurate design tool while providing a convenient and generalized mathematical form for modeling ER and MR fluids. Theoretical and experimental analyses are presented for a MR fluid damper, which is designed, developed, and tested at the University of Nevada, Reno (UNR).
Some novel designs to minimize the angular sensitivity of FSS structures (1994)

To reduce the angular and polarization sensitivity of FSS structures, various novel geometries such as double layered periodic structures composed of open or shorted square rings are proposed as cell elements. Results are presented to demonstrate the feasibility of removing the angular constraints upon the “reflective characteristics” of a resonating FSS. Logical steps that led to the proposed geometry will be pointed out as well.

Effects of Continuous Positive Airway Pressure Treatment on Cognitive Functions in the Korean Elderly with Obstructive Sleep Apnea (2016)

Background and ObjectiveaaObstructive sleep apnea (OSA) in elderly is accompanied by cognitive decline. However, it is not well known whether these deleterious changes can be reversed by continuous positive airway pressure (CPAP) treatment. Therefore, we aimed to elucidate the effect of CPAP on cognitive function in the Korean elderly with OSA. MethodsaaForty-two patients ( 60 yrs) with moderate-to-severe OSA and 41 normal controls were enrolled, and divided into treated subjects with CPAP (n = 28) and non-treated subjects (n = 14). We performed baseline measurements of cognition using the Korean version of the consortium to establish a registry for Alzheimer's disease neuropsychological battery. Additionally, digit span test, Stroop color and word test (SCW) and executive clock drawing task were applied. About 175.6 days later, second measurements of cognitive function were completed. resultsaaOSA groups had higher body mass index than normal controls (t = 3.132, p = 0.002). In comparison of cognition, OSA groups showed more decline in digit span test (forward; t = -3.647, p = 0.001, backward; t = -7.925, p < 0.001) with Bonferroni correction. In the OSA group, subjects with CPAP treatment were younger (t = 2.787, p = 0.008) and had a longer education years (t = 2.419, p = 0.020) than non-treated subjects. In comparison of cognition after CPAP treatment, they showed significant improvement in the executive function (SCW; F = 5.660, p = 0.023) after adjusting the age and education years, considering interaction effect with time and groups. ConclusionsaaShort-term CPAP treatment could improve executive function, but might not be effective on other cognitions in the elderly with OSA. Future study with long-term CPAP is required to evaluate beneficial effects on cognitive dysfunctions in elderly with OSA.
Treatment strategies for myasthenia gravis: an update (2012)

Evidence supporting the use of methotrexate and rituximab in MG has been published recently, in addition to conflicting randomized trials that were not successful, evaluating the use of tacrolimus as a steroid sparing agent. New promising treatments are currently under evaluation in clinical trials, such as belimumab and eculizumab.
Endothelial Progenitor Cells Significantly Contribute to Vasculatures in Human and Mouse Breast Tumors (2008)

The development of blood supply is crucial to the growth and progression of breast tumors. However, the contribution and role of endothelial progenitor cells (EPCs) in blood vessel formation in human breast tumors is undefined. Here, we demonstrate for the first time that ~68% of the cells integrated into vasculatures in late stage human breast tumors express CD34 and CD133 (the putative EPC markers). We also demonstrate that metastatic human breast cancer and mouse mammary gland carcinomas (MGCas) aberrantly express granulocyte colony-stimulating factor (G-CSF). Inhibition of the MGCa-derived G-CSF significantly decreased the numbers of EPCs in circulation and tumor vasculatures, as well as microvascular density and growth of transplanted MGCa in mice. These results indicate that EPCs may significantly contribute to blood vessel formation in advanced stage, G-CSF-expressing breast tumors and that patients with G-CSF-producing breast tumors may benefit from angiotherapeutic protocols that inhibit G-CSF-mediated neovascularization.
Improved Gas Response at Room Temperature of Activated Nanocrystalline WO3Films (2004)

Advanced reactive gas deposition was used to produce pure and Auactivated nanocrystalline WO3 films for gas-sensing studies. Many different methods – such as X-ray diffraction, X-ray photoelectron spectroscopy, energy dispersive spectroscopy, scanning electron microscopy, and atomic force microscopy – were used to characterize structural properties of the films. The WO3 particles in the films had the high-temperature tetragonal crystal structure after deposition, and the average crystallite size was about 10nm. The effect of sintering on structural, electrical, and gassensing properties of both pure and Au-activated WO3 films was also studied. Gas response experiments with films on alumina substrate were done at different operation temperatures, from room temperature up to about 450°C, at exposure to different concentrations of H2S and H2 in dry synthetic air.
The Product of Duration and Amount of Proteinuria (Proteinuria Index) Is a Possible Marker for Glomerular and Tubulointerstitial Damage in IgA Nephropathy (2002)

The natural course of IgAN is steadily progressive depending on the duration and amount of proteinuria. The product of these two factors (proteinuria index) may be a useful predictor for glomerular and interstitial histopathological changes and the fate of renal function in IgAN.
Multiple scattering in fish and zooplankton acoustics is the exception (1999)

Reference is made to the general literature on multiple scattering. This indicates that multiple scattering is negligible if the following condition is fulfilled: ρ≪2πλ−2σ−1/2, where ρ is the numerical density of scatterers, λ is the acoustic wavelength, and σ is the maximum single-scatterer differential scattering cross section. The condition is examined for three classes of aquatic organisms: fish, euphausiids, and copepods. It is amply satisfied for all plausible organism concentrations and frequencies excepting possibly those of schooling swimbladder-bearing fish at resonance.

Muscle IL1 Drives Ischemic Myalgia via ASIC3-Mediated Sensory Neuron Sensitization (2016)

Here, we have described a novel pathway whereby increased inflammation within the muscle tissue during ischemia/reperfusion injury sensitizes group III and IV muscle afferents via upregulation of acid-sensing ion channel 3 (ASIC3), leading not only to alterations in mechanical and chemical responsiveness in individual afferents, but also to pain-related behavioral changes. Furthermore, these I/R-induced changes can be prevented using an afferent-specific siRNA knock-down strategy targeting either ASIC3 or the upstream mediator of its expression, interleukin 1 receptor 1. Therefore, this knowledge may contribute to the development of alternative therapeutics for muscle pain and may be especially relevant to pain caused by issues of peripheral circulation, which is commonly observed in disorders such as complex regional pain syndrome, sickle cell anemia, or fibromyalgia.
Extensive Biopsies and Transurethral Prostate Resection in Men With Previous Negative Biopsies and High or Increasing Prostate Specific Antigen (2009)

About a fourth of patients with at least 2 extended negative sets of prostate biopsies remain at risk for prostate cancer and most tumors missed on initial procedures are clinically significant. Repeat biopsy using general anesthesia detects three-fourths of these prostate cancers. However, the diagnostic yield of transurethral prostate resection appears significant and may provide additional data of clinical importance in select, informed patients.
Dealerless Corporate Key Generation for Identity-Based Encryption Schemes (2016)

In Identity-Based Encryption (IBE) system, the Private Key Generator (PKG) holds the master secret key and is responsible for generating private keys for the users. This incurs the key-escrow problem, i.e. the PKG can decrypt any user' any ciphertexts without any possible detection. Also, compromising the master secret key will enable an adversary to do anything to the whole system, and having the master secret key be unavailable implies that new users cannot obtain private keys from the PKG, and existing users cannot get their private keys back from the PKG when they lost them. To address the key-escrow problem and protect the master secret key as much as possible with strong security and availability, distributed PKG protocols supporting threshold policy have been adopted in some IBE schemes. In this paper, we propose a distributed PKG protocol that supports the policy to be any monotonic access structures. Also, we propose the first distributed PKG protocol that supports the dynamic changes of the PKGs and the policy, while remaining the master secret key unchanged. The two protocols do not need any third party acting as a trusted dealer to present, and the master secret key should never be generated or resided in any one single site. The protocols are applicable to a generic IBE template, which covers many existing important IBE schemes. When applied to this generic type of IBE schemes, the two distributed PKG protocols do not affect the encryption and decryption algorithms, and only each user knows his own private key.
