Advanced model-based software engineering technologies for software defined radio configuration (2010)

Model based technologies can be used to reduce the cost of development and maintenance software intensive systems and to enable additional capabilities such as load time configuration and run time adaptation. Such systems include complex communications systems based on software defined radios that have adaptive or cognitive capabilities. Advanced methodologies and tools for developing adaptive software are needed to build such systems at an acceptable cost while maintaining safety and correctness. We have developed such methodologies and tools and have used two experimental platforms to validate them in realistic domains: 1) Flight control and vehicle management software and 2) Software defined radios. The overall goal is to demonstrate a 90% (10 X) savings in software development time and cost compared to conventional, non-model based technologies. In this presentation we will describe our application of model-based techniques to the dynamic configuration of software defined radios in the field according to mission context, environmental conditions and resource constraints.
Passive Polarimetric Imagery Based Material Classification For Remote Sensing Applications (2008)

Passive imaging polarimetry has emerged as a useful tool in many remote sensing applications including material classification, target detection and shape extraction. In this paper we present a method to classify specular objects based on their material composition from passive polarimetric imagery. The proposed algorithm is built on an iterative, model-based method to recover the complex index of refraction of a specular target from multiple polarization measurements. The recovered parameters are then used to discriminate between objects by employing the nearest neighbor rule. Experimental results indicate that the classification approach is highly effective for distinguishing between various targets of interest. Most significantly, the proposed classification method is robust to a wide range of observational geometry.
Further studies on the evidence for a 17-keV neutrino in adoped14germanium detector (1995)

We have studied the beta spectrum of $^{14}\mathrm{C}$ using a unique $^{14}\mathrm{doped}$ germanium detector. In 1991 an initial report was made of a distortion in the spectrum that could be explained by the emission of a 17-keV neutrino in approximately 1% of the decays. Further tests have shown that the observed distortion was most likely caused by systematic effects related to the detector's active guard ring. A new measurement with a smaller data sample shows no sign of this distortion. In addition, we find the Q value of $^{14}\mathrm{C}$ decay to be 155.95\ifmmode\pm\else\textpm\fi{}0.07(stat.)\ifmmode\pm\else\textpm\fi{}0.21(sys.) keV, in disagreement with a previous precision measurement.
Evaluation of Microbiological Diagnostic Techniques in Postoperative Endophthalmitis in the Endophthalmitis Vitrectomy Study (1997)

The vitreous was a richer source of positive cultures and high colony counts than was the aqueous, either because it is more supportive of bacterial growth or because a somewhat larger inoculum of the vitreous than of aqueous could be obtained. The result of Gram stain should not determine the choice of antibiotic drugs in the treatment of endophthalmitis. Vitrectomy, with culture of the vitrectomy cassette fluid, did not produce significantly more positive cultures than tap or biopsy material, and the procedure should not be performed to improve the microbiological yield.
Cervical Disc Arthroplasty: A Comprehensive Review of Single-Level, Multilevel, and Hybrid Procedures (2017)

Over the past decade, multiple high-quality studies have shown that single-level CDA can offer equivalent clinical outcomes with a reduction in secondary procedures and total cost when compared to ACDF. However, more recently there has been an increasing prevalence of 2-level CDA and hybrid surgery. Although the data regarding these multilevel procedures is less robust, it appears that they may be as effective as their single-level counterparts.
Placental growth factor in suspected preterm pre‐eclampsia: a review of the evidence and practicalities of implementation (2020)

Despite extensive research, the pathophysiology and prevention of pre-eclampsia remain elusive, diagnosis is challenging, and pre-eclampsia remains associated with adverse maternal and perinatal outcomes. Angiogenic biomarkers, including placental growth factor (PlGF) and soluble fms-like tyrosine kinase 1 (sFlt-1), have been identified as valuable biomarkers for preterm pre-eclampsia, accelerating diagnosis and reducing maternal adverse outcomes by risk stratification, with enhanced surveillance for high-risk women. PlGF-based testing is increasingly being implemented in clinical practice in several countries. This review provides healthcare providers with an understanding of the evidence for PlGF-based testing and describes the practicalities and challenges to implementation. TWEETABLE ABSTRACT: Placental growth factor in pre-eclampsia: evidence and implementation of testing.
Retracted: The spectrum of morphology in non‐neoplastic prostate including cancer mimics (2011)

The spectrum of morphology in non-neoplastic prostate includes lesions of prostatic epithelial origin, the most common being atrophy, including partial atrophy, adenosis (atypical adenomatous hyperplasia), basal cell hyperplasia and crowded benign glands, as well as those of non-prostatic origin, such as seminal vesicle epithelium. These lesions often mimic lower-grade prostatic adenocarcinoma whereas others, such as granulomatous prostatitis, for example, are in the differential diagnosis of adenocarcinoma, Gleason grades 4 or 5. Diagnostic awareness of the salient histomorphological and relevant immunohistochemical features of these prostatic pseudoneoplasms is critical to avoid rendering false positive diagnoses of malignancy.
Development of a HPLC/Tandem-MS Method for the Analysis of the Larvicides Methoprene, Hydroprene, and Kinoprene at Trace Levels Using Diels−Alder Derivatization (2005)

The invasion and subsequent spread of the mosquito-borne West Nile virus in the United States has resulted in increased use of methoprene. With the increased need for sensitive detection and monitoring of methoprene in the environment, an analytical LC/ESI-MS/MS method has been developed for the analysis of methoprene and two analogues, kinoprene and hydroprene, in water. To improve the ionization efficiency of the nonpolar analytes, a derivatization step with the Cookson-type reagent 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) was used. Derivatization improved the limit of detection 100-fold. For tandem MS analyses, limits of detection in environmental water samples (S/N = 3) are about 6 pg/mL for methoprene and 20 pg/mL for kinoprene and hydroprene, resulting in limits of quantification (S/N = 10) of 20 pg/mL for methoprene and 60 pg/mL for hydroprene and kinoprene extracted from 10 mL of water. This method was applied to measure methoprene concentrations in water samples from a treated site.

High-Voltage Pulse Generations by Power Conditioning of Flux Compression Generators (2007)

Summary form only given. Flux compression generators (FCGs) are devices that convert explosive energy into electromagnetic energy. FCGs are ideally suited for storing electromagnetic energy into an inductive load of low impedance, but not good for supplying fast-rising high-voltage pulse to a load of high impedance. For the purpose of powering high impedance loads such as microwave generators by using FCGs, a system, which can condition the output power of FCG, is needed. A power conditioning system generally consists of a storage inductor, an opening switch, a high-voltage transformer, and a closing switch. In this paper, three kinds of power conditioning systems were designed and the output properties of those were measured and analyzed. The first consisted of an explosively formed fuse opening switch (FOS), an epoxy molded pulsed transformer, and a water resistor load. The second consisted of a copper foil FOS, an epoxy molded pulsed transformer, and a carbon resistor load. The last consisted of a storage inductor, a thin copper wire FOS, and a capacitive load. In the tests, three systems supplied the high- voltage pulses of 172.7 kV, 118.0kV, and 811.0 kV, respectively. The detailed design and test results will be discussed in the presentation.
Hydrophobic-cluster analysis of plant protein sequences. A domain homology between storage and lipid-transfer proteins (1988)

Hydrophobic-cluster analysis was used to characterize a conserved domain located near the C-terminal amino acid sequence of wheat (Triticum aestivum) storage proteins. This domain was transformed into a linear template for a global search for similarities in over 5200 protein sequences. In addition to proteins that had already been found to exhibit homology to wheat storage proteins, a previously unreported homology was found with non-specific lipid-transfer proteins from castor bean (Ricinus communis) and from spinach (Spinacia oleracea) leaf. Hydrophobic-cluster analysis of various members of the present protein group clearly shows a typical domain structure where (i) variable and conserved domains are located along the sequence at precise positions, (ii) the conserved domains probably reflect a common ancestor, and (iii) the unique properties of a given protein (chain cut into subunits, repetitive domains, trypsin-inhibitor active site) are associated with the variable domains.
High Versus Low Load Resistance Training: The Effect of 24 Weeks Detraining on Serum Brain Derived-Neurotrophic Factor (BDNF) in Older Adults. (2017)

Our results show that a 12-weeks LOW+ resistance exercise increases circulating BDNF in older male subjects but that this reduces back to baseline levels after 24 weeks of detraining. Continuous exercise adherence seems to be needed to sustain the training-induced effects on BDNF in older persons. Additional studies are needed to unravel the underlying mechanisms, as well as to confirm the observed sex difference.
Gecko adhesion: evolutionary nanotechnology (2008)

If geckos had not evolved, it is possible that humans would never have invented adhesive nanostructures. Geckos use millions of adhesive setae on their toes to climb vertical surfaces at speeds of over 1ms-1. Climbing presents a significant challenge for an adhesive in requiring both strong attachment and easy rapid removal. Conventional pressure-sensitive adhesives (PSAs) are either strong and difficult to remove (e.g. duct tape) or weak and easy to remove (e.g. sticky notes). The gecko adhesive differs dramatically from conventional adhesives. Conventional PSAs are soft viscoelastic polymers that degrade, foul, self-adhere and attach accidentally to inappropriate surfaces. In contrast, gecko toes bear angled arrays of branched, hair-like setae formed from stiff, hydrophobic keratin that act as a bed of angled springs with similar effective elastic modulus to that of PSAs. Setae are self-cleaning and maintain function for months during repeated use in dirty conditions. Setae are an anisotropic 'frictional adhesive' in that adhesion requires maintenance of a proximally directed shear load, enabling either a tough bond or spontaneous detachment. Gecko-like synthetic adhesives may become the glue of the future-and perhaps the screw of the future as well.
The Effect of Ion Exchange Poisoning on the Ion Transport and Conduction in Polymer Electrolyte Membranes (PEMs) for Water Electrolysis (2022)

In water electrolyzers, polymer electrolyte membranes (PEMs) such as Nafion can accumulate cations stemming from salt impurities in the water supply, which leads to severe cell voltage increases. This combined experimental and computational study discusses the influence of sodium ion poisoning on the ionic conductivity of Nafion membranes and the ion transport in a thereon based water electrolysis cell. Conductivities of Nafion and aqueous solutions with the same amount of dissolved cations are measured with impedance spectroscopy and compared with respect to Nafion’s microstructure. The dynamic behavior of the voltage of a water electrolysis cell is characterized as a function of the sodium ion content and current density, showing the differences of the ion transport at alternating and direct currents. These experimental results are elucidated with a physical ion transport model for sodium ion poisoned Nafion membranes, which describes a proton depletion and sodium ion accumulation at the cathode. During proton depletion, the cathodic hydrogen evolution is maintained by the water reduction that forms hydroxide ions. Together with sodium ions from the membrane, the formed hydroxide ions can diffuse pairwise into the water supply, so that the membrane’s sodium ions can be at least partly be replaced with anodically formed protons.
Modeling of ferric sulfate decomposition and sulfation of potassium chloride during grate‐firing of biomass (2013)

Ferric sulfate is used as an additive in biomass combustion to convert the released potassium chloride to the less harmful potassium sulfate. The decomposition of ferric sulfate is studied in a fast heating rate thermogravimetric analyzer and a volumetric reaction model is proposed to describe the process. The yields of sulfur oxides from ferric sulfate decomposition under boiler conditions are investigated experimentally, revealing a distribution of approximately 40% SO 3 and 60% SO 2 . The ferric sulfate decomposition model is combined with a detailed kinetic model of gas‐phase KCl sulfation and a model of K 2 SO 4 condensation to simulate the sulfation of KCl by ferric sulfate addition. The simulation results show good agreements with experiments conducted in a biomass grate‐firing reactor. The results indicate that the SO 3 released from ferric sulfate decomposition is the main contributor to KCl sulfation and that the effectiveness of ferric sulfate addition is sensitive to the applied temperature conditions. © 2013 American Institute of Chemical Engineers AIChE J , 59: 4314–4324, 2013

Hypophosphatemic Vitamin D-Resistant Rickets: Metabolic Balance Studies in a Child Receiving 1,25 Dihydroxyvitamin D3, Phosphate, and Ascorbic Acid (1978)

A child with hypophosphatemic vitamin D-resistant rickets was treated for three years with the conventional vitamin D-inorganic phosphate supplementation followed by a new therapeutic regimen consisting of 1,25 dihydroxyvitamin D3 (1,25 (OH)2D3) and half of the previous phosphate supplementation. The effectiveness of the two treatment regimens was compared by calcium, phosphate, and magnesium balance techniques and by serial radiological examinations as well as careful height measurements. In addition, the lowering of the urinary pH with ascorbic acid supplementation seems to be associated with improvement in the renal tubular reabsorption of phosphate, but its distinct effect, separate from the rest of the treatment modalities, was not tested in this study. The conventional treatment did not correct the hypophosphatemia and alkaline phosphatase elevation, whereas the 1,25 (OH)2 D3-inorganic phosphate regimen is well tolerated and effective in achieving a sustained normalization of these variables. In addition, the improved growth and healing of rickets further attest to the efficacy of the new treatment.
A video rate 16*16 discrete cosine transform IC (2003)

The first fully operational implementation of a complete 16*16 discrete cosine transform (DCT) on a single chip with the speed and the resolution necessary for video images is described. Using a pipelined concurrent architecture, the DCT IC was designed for real-time processing of 14.3-MHz sampled video data. Distributed arithmetic combined with bit-serial and bit-parallel structures is used to implement the required vector inner products concurrently. The chip accepts 9-bit inputs and produces 14-bit DCT coefficients. The circuit has been laid out using the symbolic design tool MULGA. The chip contains approximately 73000 transistors and was fabricated using a double metal n-well 2- mu m CMOS technology.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Mutual coupling between millimeter-wave dielectric-resonator antennas (1999)

The mutual coupling between aperture coupled cylindrical dielectric-resonator antennas (DRAs) is analyzed using the finite-difference time domain method. The perfectly matched layer is used as absorbing boundary conditions. The voltage excitation source of microstrip structure is based on the Zhao's model, in which the source plane or the terminal plane can be moved very close to the discontinuity so that the computational domain can be reduced substantially. The numerical results are verified by measurements and reasonable agreement between theory and experiment is obtained. It is shown that this method is highly efficient for the analysis of DRAs.
Computer aided detection of lung cancer in the absence of the cancer on chest radiographs: effect of the computer-aided detection on radiologists' performance on cancer-free cases (2005)

Using data from a clinical trial of a commercial CAD system for lung cancer detection we separately analyzed the location, if any, selected on each film by 15 radiologists as they interpreted chest radiographs, 160 of which did not contain cancers. On the cancer-free cases, the radiologists showed statistically significant difference in decisions while using the CAD (p-value 0.002). Average specificity without computer assistance was 78%, and with computer assistance 73%. In a clinical trial with CAD for lung cancer detection there are multiple machine false positives. On chest radiographs of older current or former smokers, there are many scars that can appear like cancer to the interpreting radiologists. We are reporting on the radiologists' false positives and on the effect of machine false positive detections on observer performance on cancer-free cases. The only difference between radiologists occurred when they changed their initial true negative decision to false positive (p-value less than 0.0001), average confidence level increased, on the scale from 0.0 to 100.0, from 16.9 (high confidence of non-cancer) to 53.5 (moderate confidence cancer was present). We are reporting on the consistency of misinterpretation by multiple radiologists when they interpret cancer-free radiographs of smokers in the absence of CAD prompts. When multiple radiologists selected the same false positive location, there was usually a definite abnormality that triggered this response. The CAD identifies areas that are of sufficient concern for cancer that the radiologists will switch from a correct decision of no cancer to mark a false positive, previously overlooked, but suspicious appearing cancer-free area; one that has often been marked by another radiologist without the use of the CAD prompt. This work has implications on what should be accepted as ground truth in ROC studies: One might ask, "What a false positive response means?" when the finding, clinically, looks like cancer-it just isn’t cancer, based on long-term follow-up or histology.
