Mode I Interlaminar Fracture Toughness of Composites Using Slender Double Cantilevered Beam Specimens (1985)

The use of slender double cantilever beam specimens for measuring the mode I in terlaminar fracture toughness was critically evaluated. Experiments were performed with unidirectional composites to judge the validity of using data from multiple crack jumps on a single specimen. Three approaches for calculating the strain energy release rate were compared. These included an energy rate determination of the J I -integral, a compliance calibration procedure and an analytical equation based on linear beam bending. The fracture toughness was overestimated by the latter two approaches. Per manent deflection was seen to accumulate in the arms of the double cantilever beam specimens as the cracked surface area increased. This component of deflection must be accounted for in all forms of analysis with DCB specimens.
Partitioning a network into n pieces with a time-efficient net cost function (1991)

This paper discusses the generalization of the Fiduccia-Mattheyses linear time bi-partitioning algorithm to a linear time n-partitioning algorithm. It uses a new heuristic cost function to evaluate the cost of arbitrarily large spanning trees in O(log n) time. Practical experiments show good results.
Serological signatures of SARS-CoV-2 infection: Implications for antibody-based diagnostics (2020)

Abstract Background Infection with SARS-CoV-2 induces an antibody response targeting multiple antigens that changes over time. This complexity presents challenges and opportunities for serological diagnostics. Methods A multiplex serological assay was developed to measure IgG and IgM antibody responses to seven SARS-CoV-2 spike or nucleoprotein antigens, two antigens for the nucleoproteins of the 229E and NL63 seasonal coronaviruses, and three non-coronavirus antigens. Antibodies were measured in serum samples from patients in French hospitals with RT-qPCR confirmed SARS-CoV-2 infection ( n = 259), and negative control serum samples collected before the start of the SARS-CoV-2 epidemic ( n = 335). A random forests algorithm was trained with the multiplex data to classify individuals with previous SARS-CoV-2 infection. A mathematical model of antibody kinetics informed by prior information from other coronaviruses was used to estimate time-varying antibody responses and assess the potential sensitivity and classification performance of serological diagnostics during the first year following symptom onset. A statistical estimator is presented that can provide estimates of seroprevalence in very low transmission settings. Results IgG antibody responses to trimeric Spike protein identified individuals with previous RT-qPCR confirmed SARS-CoV-2 infection with 91.6% sensitivity (95% confidence interval (CI); 87.5%, 94.5%) and 99.1% specificity (95% CI; 97.4%, 99.7%). Using a serological signature of IgG and IgM to multiple antigens, it was possible to identify infected individuals with 98.8% sensitivity (95% CI; 96.5%, 99.6%) and 99.3% specificity (95% CI; 97.6%, 99.8%). Informed by prior data from other coronaviruses, we estimate that one year following infection a monoplex assay with optimal anti-S tri IgG cutoff has 88.7% sensitivity (95% CI: 63.4%, 97.4%), and that a multiplex assay can increase sensitivity to 96.4% (95% CI: 80.9%, 100.0%). When applied to population-level serological surveys, statistical analysis of multiplex data allows estimation of seroprevalence levels less than 1%, below the false positivity rate of many other assays. Conclusion Serological signatures based on antibody responses to multiple antigens can provide accurate and robust serological classification of individuals with previous SARS-CoV-2 infection. This provides potential solutions to two pressing challenges for SARS-CoV-2 serological surveillance: classifying individuals who were infected greater than six months ago, and measuring seroprevalence in serological surveys in very low transmission settings.
Her-2/neu status in breast cancer metastases to the central nervous system. (2003)

When FISH is the detection method, CNS metastases accurately reflect the HER-2/neu status of the primary tumor. Central nervous system metastases from breast cancer received as surgical specimens can therefore be used to assess HER-2/neu status in patients in whom the primary tumor is unavailable for analysis.
Quantitative trait loci in Two Soybean Recombinant Inbred Line Populations Segregating for Yield and Disease Resistance (2002)

Molecular makers linked to quantitative trait loci (QTL) can assist soybean [Glycine max (L.) Merr.] breeders to combine traits of low heritability, such as yield, with disease resistance. The objective of this study was to identify markers linked to yield QTL in two recombinant inbred line (RIL) populations ['Essex' x 'Forrest' (ExF; n = 100) and 'Flyer' x 'Hartwig' (FxH; n = 94)] that also segregate for soybean cyst nematode (SCN) resistance genes (rhg1 and Rhg4). Each population was yield tested in four environments between 1996 and 1999. The resistant parents produced lower yields. Heritability of yield across four environments was 47% for ExF and 57% for FxH. Yield was normally distributed in both populations. High yielding, SCN resistant transgressive segregants were not observed. In the ExF RIL population, 134 microsatellite markers were compared against yield by ANOVA and MAPMAKER QTL. Regions associated with yield were identified by SATT294 on linkage group (LG.) C1 (P = 0.006, R(2) = 10%), SATT440 on LG. I (P = 0.007, R(2) = 10%), and SATT337 on LG. K (P = 0.004, R(2) = 10%). Essex provided the beneficial allele at SATT337. Mean yields among FxH RILs were compared against 33 microsatellite markers from LG. K. In addition 136 markers from randomly selected LGs were compared with extreme phenotypes by bulk segregant analysis. Two regions on LG. K (20 cM apart) associated with yield were identified by SATT326 (P = 0.0004, R(2) = 15%) and SATT539 (P = 0.0008, R(2) = 14%). Flyer provided both beneficial alleles. Both populations revealed a yield QTL in the interval (5 cM) between SATT337 and SATT326. These populations may share a common allele for yield in this region, given that about 40% of Flyer genome derived from Essex.

Enhancement of Vascular Structures in3D and 2D Angiographic Images (2016)

A number of imaging techniques are being used for diagnosis and treatment of vascular pathologies like stenoses, aneurysms, embolisms, malformations and remodelings, which may affect a wide range of anatomical sites. For computer-aided detection and highlighting of potential sites of pathology or to improve visualization and segmentation, angiographic images are often enhanced by Hessian based filters. These filters aim to indicate elongated and/or rounded structures by an enhancement function based on Hessian eigenvalues. However, established enhancement functions generally produce a response, which exhibits deficiencies such as poor and non-uniform response for vessels of different sizes and varying contrast, at bifurcations and aneurysms. This may compromise subsequent analysis of the enhanced images. This paper has three important contributions: i) reviews several established enhancement functions and elaborates their deficiencies, ii) proposes a novel enhancement function, which overcomes the deficiencies of the established functions, and iii) quantitatively evaluates and compares the novel and the established enhancement functions on clinical image datasets of the lung, cerebral and fundus vasculatures.

Sugammadex-Induced Hypersensitivity Reaction in a Pediatric Patient (2018)

We report a case of a 3-year-old boy who administered sugammadex and developed an allergic reaction several minutes after the administration. He developed an increase in airway pressures and a decrease in peripheral oxygen saturation; auscultation revealed widespread wheezing in the lungs. He was successfully treated with immediate administration of methylprednisolone, pheniramine, and theophylline. We assumed an allergic reaction to sugammadex based on the clinical condition of the patient.
In vitro evaluation of nutrients that selectively confer a competitive advantage to lactobacilli (2015)

An assay was developed that tested the ability of Lactobacillus acidophilus to outcompete a challenge of Escherichia coli in a mixed culture containing different test nutrients. Using this assay, addition of fructo-oligosaccharide to the media allowed L. acidophilus to outcompete a challenge of E. coli, whereas in a mixed culture without the prebiotic the trend was reversed. Growth curves generated for E. coli in a single culture showed that fructo-oligosaccharide did not affect growth, indicating that the carbohydrate was not toxic to E. coli. This indicates that fructo-oligosaccharides may increase the ability of beneficial microbes to outcompete a pathogenic challenge. These results were confirmed using a skin simulant model that incorporates growth of the organisms at an air-surface interface to mimic the vulvar environment. It is possible to use a co-culture assay as an in vitro screening tool to define nutrients that confer a competitive advantage to beneficial flora specific to the female urogenital tract.
Helminths as therapeutic agents for inflammatory bowel disease (2004)

Over the last decade major advances have been made in our understanding of the mechanisms and mediators of inflammation that hold the promise of the development of new therapies for inflammatory disease. While much is to be gleaned from the application of new technologies, assessment of the age-old host-parasite relationship may also provide insights on how to counter pathological inflammatory events. In the case of inflammatory bowel disease [particularly Crohn's disease, which is associated with T helper 1 (Th1) events] it is proposed that infection with parasitic helminths would be beneficial: the paradigm being that of immune deviation, where Th2 cytokines mobilized in response to the helminth will prevent or antagonize the disease-promoting Th1 events in the gut. The situation is unlikely to be this simple. Here we review and critique the data in support of helminth therapy for inflammatory bowel disease, drawing attention to the gaps in knowledge and presenting a view on how the field may be advanced. While the concept of helminth therapy may be superficially unappealing, this review may convince the reader of the value of more extensive analyses of the impact of helminth infection on enteric inflammation.

Prediction of Falling Cylinder Through Air-Water-Sediment Columns (2005)

A falling rigid body through air, water, and sediment is investigated experimentally and theoretically. Two experiments were conducted to drop rigid cylinders with density ratio around 1.8 into shallow water (around 13 m deep) in the Monterey Bay (Exp-1) and into the Naval Postgraduate School’s swimming pool (Exp-2). During the experiments, we carefully observe cylinder track and burial depth while simultaneously taking gravity cores (in Exp-1). After analyzing the gravity cores, we obtain the bottom sediment density and shear strength profiles. The theoretical work includes the development of a 3D rigid body impact burial prediction model (IMPACT35) that contains three components: triple coordinate transform and hydrodynamics of a falling rigid object in a single medium (air, water, or sediment) and in multiple media (air-water and water-sediment interfaces). The model predicts the rigid body’s trajectory in the water column and burial depth and orientation in the sediment. The experimental data (burial depth, sediment density, and shear strength) show the capability of IMPACT35 in predicting the cylinder’s trajectory and orientation in a water column and burial depth and orientation in sediment.
Redox enzyme-mimicking activities of CeO2 nanostructures: Intrinsic influence of exposed facets (2016)

CeO<sub>2</sub> nanoparticles (NPs) have been well demonstrated as an antioxidant in protecting against oxidative stress-induced cellular damages and a potential therapeutic agent for various diseases thanks to their redox enzyme-mimicking activities. The Ce<sup>3+</sup>/Ce<sup>4+</sup> ratio and oxygen vacancies on the surface have been considered as the major originations responsible for the redox enzyme-mimicking activities of CeO<sub>2</sub> NPs. Herein, CeO<sub>2</sub> nanostructures (nanocubes and nanorods) exposed different facets were synthesized via a facile hydrothermal method. The characterizations by X-ray photoelectron spectroscopy, Raman spectroscopy, and UV-Vis spectroscopy show that the Ce<sup>3+</sup>/Ce<sup>4+</sup> ratio and oxygen vacancy content on the surfaces of as-synthesized CeO<sub>2</sub> nanostructures are nearly at the same levels. Meanwhile, the enzymatic activity measurements indicate that the redox enzyme-mimicking activities of as-synthesized CeO<sub>2</sub> nanostructures are greatly dependent on their exposed facets. CeO<sub>2</sub> nanocubes with exposed {100} facets exhibit a higher peroxidase but lower superoxide dismutase activity than those of the CeO<sub>2</sub> nanorods with exposed {110} facets. Our results provide new insights into the redox enzyme-mimicking activities of CeO<sub>2</sub> nanostructures, as well as the design and synthesis of inorganic nanomaterials-based artificial enzymes.
Characterization of Indium Tin Oxide and Reactive Ion Etched Indium Tin Oxide Surfaces (1990)

ITO films, both before and after annealing, were characterized with various methods. The changes in film characteristics are discussed. RIE etching mechanisms for the unannealed ITO films in three reactive gases (CF 2 Cl 2 , CF 3 Cl, and CF 4 ) and two diluent gases (N 2 and Ar) were delineated by analyzing and comparing the surface ESCA data with the process results. For undiluted gases, indium is the major component left on the surface, and each gas has its own etch preference for different components. The addition of a diluent into the plasma may change the surface composition as well as the etching mechanisms. To increase the whole film etch rate, each component has to be etched off effectively.
Transformation of industrial wastewater into copper–nickel nanowire composites: straightforward recycling of heavy metals to obtain products of high added value (2020)

Large amounts of industrial metal containing process and waste solutions are a growing issue. In this work, we demonstrated that they could be transformed into materials of high added values such as copper-nickel nanowires (CuNi NWs) by simple chemical reduction. A thorough investigation of the parameter space was conducted. The microstructure of the obtained material was found tunable depending on the employed concentration of precursor, reducing agent, capping agent, pH, temperature, and reaction time. Moreover, the obtained product had a strong magnetic character, which enabled us to separate it from the reaction medium with ease. The results open new perspectives for materials science by proposing a new type of nanostructure: composite NWs of very promising properties, with metallic elements originating directly from industrial process solution.
Hospital readmission for adult acute sickle cell painful episodes: frequency, etiology, and prognostic significance (2005)

The acute sickle cell painful episode is the most common cause of hospitalization of patients with sickle cell anemia. Its detailed clinical features and peri-discharge features are not well known. In order to determine the actual pattern of hospital admissions of patients with SS and the causes of frequent hospital readmissions and their prognostic significance, we conducted a prospective longitudinal and observation cohort study of all adult patients with sickle cell anemia admitted to Thomas Jefferson University Hospital between January 1998 and December 2002. Major outcome measures included the frequency, etiology, and prognostic significance of readmissions to the hospital within 1 week and 1 month after discharge. Incidence of mortality among patients during the study period was also determined. Analysis of the data showed that about 50% of hospital admissions for acute painful episodes were readmitted within 1 month after discharge, and about 16% of all admissions were within 1 week after discharge. The intensity of pain score decreased significantly during the first 4 days of hospital admission (P < 0.001) and then reached a plateau until discharge. The mean score of pain intensity was >7 throughout the hospital stay. Causes of hospital readmission included premature discharge, withdrawal syndrome, and recurrence of new acute episodes. Readmission within 1 week after discharge was associated with higher mortality than otherwise. This study shows that hospital readmission of adult patients with sickle cell anemia is common. It suggests that improvement is needed in the management of pain during hospitalization and at home after discharge. Patients who are readmitted frequently within 1 week of discharge have poor prognosis and require careful monitoring.
Fabrication and Characterization of High Performance Intermediate Temperature Micro-Tubular Solid Oxide Fuel Cells (2016)

A phase inversion-based dual-layer co-extrusion approach was advanced to fabricate micro-channel array structured micro-tubular solid oxide fuel cells (MT-SOFCs). The inner graphite layer was used as a sacrificial layer to eliminate the middle sponge-like layer and inner surface dense skin layer, which were normally formed using the single layer extrusion method. As a result, the micro-channel array generated in the outer layer was a more open structure and facile fuel/gas diffusion was obtained. The fuel/gas permeability of such an anode substrate Ni-Ce0.8Sm0.2O1.9 (Ni-SDC) was ∼9 times that of an anode substrate fabricated using the phase inversion-based single layer extrusion method. The open circuit voltages (OCVs) of the corresponding cell Ni-SDC/SDC/PrBaCo2O5+δ were 0.89 V–0.85 V at 500–600°C, much higher than those of other SDC electrolyte based MT-SOFCs. The peak power density of the cell was ∼1484 mW cm−2 at 600°C, approximately 1.5 times that of a similar cell with an anode substrate fabricated from the single layer extrusion method. This is also the highest performance among the SOFCs with the same material system in open literature. The fuel utilization rate was also significantly improved in different degrees depending on the supplied inlet fuel flow rates.
Hf-silicate inter-poly dielectric technology for sub 70nm body tied FinFET flash memory (2005)

We report for the first time on 256Mb NOR-type body tied FinFET flash memory using Hf silicate IPD (inter poly dielectric) and compare with FinFET flash memory using traditional ONO IPD. An enlarged coupling ratio through Hf silicate IPD enhanced a CHEI (channel hot electron injection) programming speed and made the operation voltage down. And we could obtain a higher erasing speed resulted from HHI (hot hole injection) erase than that of F-N tunneling without degrading endurance characteristics.

An ultra flat phased array Ku-band antenna with integrated receivers in SiGe BiCMOS (2015)

A highly integrated Ku-band (10.7–12.75 GHz) planar phased array receiver of 64 antenna elements is presented. It features instantaneous reception of the full Ku-band (2.05 GHz wide) in two orthogonal polarizations with wide scan angles by using time delay instead of phase shift. The receiver is part of a system for satellite broadcast TV reception on board of moving vehicles. Two SiGe radio frequency integrated circuits (RFICs) were developed, packaged in ceramic BGAs and assembled onto a 15-layer printed circuit board (PCB) which integrates the antenna elements. An outline of the system is given along with a detailed description. It sets a new standard in integration density. The receiver has extensive analog signal processing at intermediate frequency (IF)-level. A novel bipolar implementation for true time delay is proposed, with a continuous programmable delay range of 0…80 ps with less than 2.5 ps group-delay variation in 2 GHz bandwidth (BW). The wide BW calls for a constant group-delay implementation in the IF chain. The receiver (RFIC) consumes only 132 mW per channel. Each channel has 40 dB gain.
