Impedance Enhancement of Textile Grounded Loop Antenna Using High-Impedance Surface (HIS) for Healthcare Applications (2020)

In this paper, impedance matching enhancement of a grounded wearable low-profile loop antenna is investigated using a high-impedance surface (HIS) structure. The wearable loop antenna along with the HIS structure is maintained low-profile, making it a suitable candidate for healthcare applications. The paper starts with investigating, both numerically and experimentally, the effects of several textile parameters on the performance of the wearable loop antenna. The application of impedance enhancement of wearable grounded loop antenna with HIS structure is then demonstrated. Numerical full-wave simulations are presented and validated with measured results. Unlike the grounded wearable loop antenna alone with its degraded performance, the wearable loop antenna with HIS structure showed better matching performance improvement at the 2.45 GHz-band. The computed overall far-field properties of the wearable loop antenna with HIS structure shows good performance, with a maximum gain of 6.19 dBi. The effects of bending the wearable loop antenna structure with and without HIS structure as well as when in close proximity to a modeled human arm are also investigated, where good performance was achieved for the case of the wearable antenna with the HIS structure.
Improving multicast throughput in mobile ad-hoc networks using cross-layer signaling mechanism (2011)

A significant portion of communication across tactical edge networks includes multicast traffic to support collaboration among many separate multicast groups. In order to provide a reliable and scalable network, it is critical to optimize its multicast performance. However, multicast traffic performance in radio networks is limited by the data link layer design for distribution of multicast traffic to its neighbors. In many situations, local distribution is derived by the neighbor with weakest RF link. For example, when the Network layer forwards a multicast packet the MAC layer will use the lowest link state among all its neighbors to transmit that packet. This can result in reduction of available bandwidth for multicast transmission in situations when at least one neighbor with the lowest link state exists. One method to alleviate this problem is to disable lowest state for data delivery and routing. However this approach can result in network fragmentation when a neighbor is in line of sight but only available at the lowest state. An extreme example of this is when the lowest state link is the only link available between two network partitions (bridge), in this case the network will be fragmented. In this paper we examine the possibilities for cross layer optimization by using the lowest link state judicially, only at times when performance with other neighbor nodes is not affected. We will explore the benefit and tradeoff of different approaches in this paper and analyze the performance benefits that we can expect to achieve.
Evolution of size, morphology, and magnetic properties of CuO nanoparticles by thermal annealing (2009)

Cupric oxide (CuO) nanoparticles with different morphologies were synthesized by thermal annealing of the copper hydroxide at various temperatures. Significant changes in both the particle size and the morphology with the annealing temperature (TA) were observed. The average particle size (d) increases from 13 to 33 nm and the morphology varies from ellipsoidal to rodlike as TA increases from 150 to 550 °C. The formation of these morphologies is explained in terms of the variation in the interplanar H-bonds breaking rate with different temperatures. The magnetic measurements reveal the presence of weak ferromagnetic interaction and the blocking behavior in these nanoparticles. The magnetic field dependence of the superparamagnetic blocking temperature (TB) follows the Brown equation. In addition, the linear variation in zero field cooled susceptibility with particle size is consistent with the predictions of Néel model for the uncompensated spins. These surface spins are responsible for the observed anomalous magnetic properties of CuO nanoparticles.
Prevalence of Inflammatory Bowel Disease Among Adults Aged ≥18 Years — United States, 2015 (2016)

Crohn's disease and ulcerative colitis, collectively known as inflammatory bowel disease (IBD), are characterized by chronic inflammation of the gastrointestinal tract (1). IBD has been associated with poor quality of life and extensive morbidity and often results in complications requiring hospitalizations and surgical procedures (2-4). Most previous studies of IBD have used administrative claims data or data collected from limited geographic areas to demonstrate increases in estimated prevalence of IBD within the United States (5,6). Few national prevalence estimates of IBD among adults based on large, nationally representative data sources exist, and those that do tend to be based on older data. For example, the most recent national study used 1999 National Health Interview Survey (NHIS) data and estimated that 1.8 million (0.9%) U.S. adults had IBD (7). To examine the prevalence of IBD among the civilian, noninstitutionalized U.S. adult population, data from the 2015 NHIS were analyzed. Overall, an estimated 3.1 million, or 1.3%, of U.S. adults have received a diagnosis of IBD. Within population subgroups, a higher prevalence of IBD was identified among adults aged ≥45 years, Hispanics, non-Hispanic whites, and adults with less than a high school level of education, not currently employed, born in the United States, living in poverty, or living in suburban areas. The use of a nationally representative data source such as the NHIS to estimate the prevalence of IBD overall and by population subgroups is important to understand the burden of IBD on the U.S. health care system.
Melt polycondensation ofL-lactic acid with Sn(II) catalysts activated by various proton acids: A direct manufacturing route to high molecular weight Poly(L-lactic acid) (2000)

Poly(L-lactic acid) (PLLA) was produced by the melt polycondensation of L-lactic acid. For the optimization of the reaction conditions, various catalyst systems were examined at different temperature and reaction times. It was discovered that Sn(II) catalysts activated by various proton acids can produce high molecular weight PLLA [weight-average molecular weight (Mw ) ≥ 100,000] in a relatively short reaction time (≤15 h) compared with simple Sn(II)-based catalysts (SnO, SnCl2 · 2H2O), which produce PLLA with an Mw of less than 30,000 after 20 h. The new catalyst system is also superior to the conventional systems in regard to racemization and discoloration of the resultant polymer. © 2000 John Wiley & Sons, Inc.

Le processus de decision des IMF en matiere de structure du capital : pour une approche plus reflechie et plus methodique (2007)

Microfinance institutions (MFIs) today have an increasingly broad range of financing sources at their disposal. This allows for greater funding diversification, but it also makes decisions about capital structure more complex. Several high-profile financing transactions for MFIs have taken place recently, including securitizations, local bond issues, the first large-scale venture capital investment in an MFI, and the first Initial Public Offering of shares. In addition, where their legal structure permits, many MFIs are launching large-scale deposit mobilization campaigns as a core funding strategy. Consultative Group to Assist the Poor (CGAP) and Grameen Foundation recently conducted a survey of MFI managers to better understand MFI capital structure decision-making processes in the face of these expanding financing options.
Penetrating Flow of Polymer Solutions into a Newtonian Fluid in Undulating Slit Channels (2002)

In order to clarify the details of the E.O.R mechanism using polymer solutions, the flow of polymer solutions penetrating into the Newtonian fluid (machine oil) in undulating slit channels was examined experimentally. Test fluids were the solutions of 0.01wt% PAA(polyacrylamide) with a different viscosity of solvent. From the observation of flow pattern, the shape of the interface between the both fluids is closely connected to the steady shear viscosity. Furthermore, it is found that the addition of PAA is effective for the recovery of the Newtonian fliud.

The acceleration responsivity of fiber-optic mandrel hydrophones (2000)

Both piezoelectric and fiber-optic hydrophones are sensitive to acceleration. The acceleration can be a major noise source in rough environment. The pressure to acceleration responsivity ratio is therefore a figure of merit for a hydrophone.
Ureas: Applications in Drug Design (2016)

The unique hydrogen binding capabilities of ureas make them an important functional group to make drug-target interactions and thus incorporated in small molecules displaying broad range of bioactivities. The related research and numerous excellent achievements of ureas applicability in drug design for the modulation of selectivity, stability, toxicity and pharmacokinetic profile of lead molecules have become active topic. This review aims to provide insights in to the significance of urea in drug design by summarizing successful studies of various urea derivatives as modulators biological targets (viz. kinases, NAMPT, soluble epoxide hydrolases, mTOR, proteases, gyrB/parE, and epigenetic enzymes (such as HDAC, PRMT or DOT1L etc.). The findings of this review confirm the importance of urea moiety in medicinal chemistry and stimulate its use as a structural motif with rational decision making approach. Keywords: Urea, drug design, pharmacokinetics, enzyme inhibitors, epigenetics, intramolecular hydrogen binding.

Beta Testing Implementation of the Purdue Time Domain Reflectometry (TDR) Method for Soil Water Content and Density Measurement (2003)

The Purdue TDR method is a new technology for simultaneously measuring soil water content and dry density insitu. An ASTM standard for using TDR to measure soil water content and dry density based on Purdue TDR method was approved during the time span of this project and is designated ASTM D6780. The primary objective of this study was to take the Purdue TDR Method to the point where it is widely field tested by users on a broad spectrum of soils around the country. This goal was achieved by involving researchers at other universities and practitioners in federal and state agencies and in private practice firms. The results and feedback was obtained from Beta Partners by Purdue University for evaluation and further analysis. Major achievements in this research include: 1) Involvement of Beta Partners - Six Beta partners including two universities, two private firms and two state DOTs were involved in this project and instructions were provided to each Beta Partners. Involving these Beta partners provided a large span of field applications and research feedback. Results from testing performed were compared with existing technologies and provided the basis for the precision and bias statements needed for ASTM D6780. Based on feedback from extensive field tests, testing procedures were improved. Meanwhile, the testing equipment was refined and integrated, which made the testing system both more robust and easier to handle. The overall cost of the testing system has also been significantly reduced, which made it more economically competitive for mass production. 2) Testing automation - A new generation of electronics was identified and incorporated into the Purdue TDR test, the new TDR100 by Campbell Scientific, Inc. Corresponding software for automation was designed and systematically improved. This provided a user friendly interface and facilitated performance of TDR testing process. Preliminary feedback from using the computer software is satisfactory. The efforts and achievements on testing automation also built up the basis for a developing a more compact package in the future. 3) One step method for TDR testing - A simplified procedure to that described by ASTM D6780 to measure soil water content and dry density was discovered, which is an important product of this project. The simplified procedure is called the one-step method since it only requires one field TDR reading. The one-step method achieved this simplification by incorporating information of bulk electrical conductivity from TDR signal in addition to the apparent
Prise en charge de l’algoneurodystrophie ou Syndrome Douloureux Régional Complexe chez l’enfant et l’adolescent : la nécessité d’une approche en équipes (2021)

Dans le cadre de consultations spécifiques pour des patients souffrant de « douleurs chroniques », nous sommes régulièrement amenés à rencontrer des enfants (en général dès l’âge de 7 ans) et des adolescents, adressés le plus souvent par des chirurgiens orthopédistes pédiatriques pour la prise en charge d’algoneurodystrophies (ou Syndrome Douloureux Régional Complexe de type 1) rebelles aux traitements antalgiques classiques. Nous décrivons notre expérience auprès de ces patients avec la nécessité de porter autant d’attention à la véracité de leur vécu douloureux qu’à leur histoire de vie, leur personnalité et les relations avec leur entourage. La réussite de la rencontre avec ces patients, leur acceptation de notre aide reposent sur la qualité de notre écoute et la pluridisciplinarité de la prise en charge : celui du médecin et du psychologue en consultation, celui des autres professionnels et des équipes relais.
TRAIL death receptors as tumor suppressors and drug targets (2008)

Various ways of targeting TRAIL-death receptors for the treatment of a diverse set of malignancies are being explored in ongoing clinical trials. Recent data of ours and others suggest that loss of the only death signaling receptor in mice (TRAIL-R) is associated with susceptibility to various stages of lymphomagenesis and carcinogenesis, perhaps in a complex cell- and model-specific manner. Myc-overexpressing B cell lymphomas with an intact TRAIL-R locus displayed a number of gene expression changes indicating resistance to TRAIL-R signaling. Herein we show some data on the use of recombinant human TRAIL (rhTRAIL) and gamma-radiation (10 Gy) in combination in an autochthonous mouse model for hepatocellular carcinoma. As cell death signaling through the death receptors is evolutionary conserved from zebra fish to man, novel genetically engineered mouse tumor models may prove useful in establishing in vivo models that excel our fundamental understanding of resistance to TRAIL-death receptor signaling, off-target effects from TRAIL-death receptor targeting compounds and help in identifying a clinically cogent rationale for efficient targeting of TRAIL death receptors in patients. Once established, mouse tumor models may prove to be a useful tool in understanding TRAIL-death receptor signaling.
Analytical theory for Bragg transmission surface relief gratings (2003)

Surface relief gratings can have high diffraction efficiencies in the “scalar” domain where the grating period is more than about ten times the illumination wavelength, as well as in the Bragg resonance domain where the grating period approaches the illumination wavelength and only three diffraction orders +1st, 0, -1st are nonevanescent. The resonance domain is of particular interest for many applications, and extensive numerical methods have been developed for analyzing and optimizing the grating parameters and trade-offs [1,2]. Typically, such numerical methods are rather cumbersome and time consuming.
Intradural extramedullary meningeal melanocytoma: a case report and literature review (2023)

Primary meningeal melanocytomas are extremely rare, benign tumours arising from the leptomeninges. While they are considered to be benign lesions, there is potential for their growth and transformation into malignant melanomas. They are commonly found in the cervical spine, with a decreased incidence in the thoracic and lumbar regions. We present a case report of a 56-year-old man who presented to our unit with a 4-month history of lower limb weakness and a sensory level at T6. Magnetic resonance imaging shows an intradural extramedullary tumour. The patient underwent a thoracic debulking of the lesion with neurophysiological monitoring. Histopathology confirmed the diagnosis of melanocytoma of meningeal origin, with a low mitotic count. Our patient recovered well post-operatively with no complications. Surgical resection is an effective method to manage this tumour; however, adjuvant radiotherapy is advised due to the risk of recurrence and malignant transformation.
SCCC Turbo Equalizer/Decoder for X-band Nano Satellite High-Speed Downlink System (2014)

To provide data rate more than 100 Mbps for nano satellite communications, we have developed an X-band downlink system with a modulation symbol rate of 100 Msps. The received signals of nano satellites tend to suffer much more distortion due to the transmitter and channel constraints. Several effective techniques based on turbo equalizer/decoder have been developed and verified via computer simulation therefore, the obtained results apply to the downlink system design.

Cavity enhanced Faraday rotation of semiconductor quantum dots (2006)

Dielectric vertical cavities are used to study the spin dynamics of molecularly self-assembled colloidal CdSe quantum dots (QDs). A quality factor dependent enhancement of Faraday rotation (∼25×) is observed and attributed to optically excited spins interacting with multiple passes of the cavity photons. This enables dynamical measurements at extremely low powers on relatively small numbers of quantum confined spins. In CdSe QDs, measurements reveal that spectroscopic contributions from exciton and electron spin precession depend on the power of excitation. We demonstrate that this scheme is amenable to chemically synthesized systems as a means to increase detection sensitivity.
A fast SPFD-based rewiring technique (2010)

Circuit rewiring can be used to explore a larger solution space by modifying circuit structure to suit a given optimization problem. Among several rewiring techniques that have been proposed, SPFD-based rewiring has been shown to be more effective in terms of solution space coverage. However, its adoption in practice has been limited due to its long runtime. We propose a novel SAT-based algorithm that is much faster than the traditional BDD-based methods. Unlike BDD-based methods that completely specify all pairs of SPFD using BDDs, our algorithm uses a few SAT instances to perform rewiring for a given wire without explicitly enumerating all SPFDs. Experimental results show that our algorithm's runtime is only 13% of that of a conventional one when each wire has at most 25 candidate wires and the runtime scales well with the number of candidate wires considered. Our approach evaluates each rewiring instance independently in the order of milliseconds, rendering deployment of an SPFD-based rewiring inside the optimization loop of synthesis tools a possibility.
