GROUNDPLANE SHAPING TECHNIQUES FOR USE WITH SATELLITE POSITIONING SYSTEMS (1986)

ABSTRACT In the use of satellite positioning systems such as the Global Positioning System (GPS) significant errors can be introduced into the indicated position through the properties of the antenna structure. Of particular interest are the phase characteristics of the antenna as a function of observation angle. The microstrip antenna features a rugged, low profile and light weight construction making it an ideal choice for practical applications, but positioning accuracy may be limited by the phase perturbations introduced by the microstrip mounting surface. The rectangular microstrip and narrow slot antennas are investigated with several groundplane types using slot theory and the Uniform Theory of Diffraction (UTD) for their applicability in GPS. Amplitude, phase and phase centre characteristics are studied with particular emphasis on the pattern response at low elevation angles which are of particular interest in hydrographic and aviation applications. Analytic and experimental data are presented to show the effects of groundplane size and shape in producing a suitable amplitude and phase response.
Synthesis and reduction of large sized graphene oxide sheets (2017)

Graphene oxide (GO) can be considered as one of the most visible outcomes of graphene research in terms of large scale production and commercialization prospects. Although GO can be easily prepared by oxidation-exfoliation of graphite in agitated solutions, the size of these sheets is generally limited due to fragmentation along fault lines during chemical oxidation and exfoliation in agitated solutions. In this account, we discuss recent strategies which have been developed for the preparation of large sized graphene oxide (LGO) sheets with lateral sizes >10 μm, using chemically expanded graphite as the starting material. LGO has a much lower density of defects than GO prepared using the conventional Hummers' method and can be readily transformed into graphene by chemical reduction. In addition, the unique advantages of using LGO sheets as a performance enhancer are discussed. Finally, this review also discusses recent advances in the chemical and electrochemical reduction of graphene oxide.
Region-based motion estimation using deterministic relaxation schemes for image sequence coding (1992)

Motion analysis studies provide efficient estimation schemes for estimating dense optical flow fields. However, for image sequence coding where motion features have to be transmitted, an adaptive compact motion representation is required to extract temporal redundancy from an image sequence with a minimum amount of side information and, nevertheless, with a high quality of reconstruction. The advantages of region-based motion descriptions are illustrated and compared to those of the usual local ones (i.e., only two purely translational components of apparent motion). A new relaxation method for compact quantitative motion estimation using a hierarchy of motion models is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

A Multiplexed Cell‐Free Assay to Screen for Antimicrobial Peptides in Double Emulsion Droplets (2022)

Abstract The global surge in bacterial resistance against traditional antibiotics triggered intensive research for novel compounds, with antimicrobial peptides (AMPs) identified as a promising candidate. Automated methods to systematically generate and screen AMPs according to their membrane preference, however, are still lacking. We introduce a novel microfluidic system for the simultaneous cell‐free production and screening of AMPs for their membrane specificity. On our device, AMPs are cell‐free produced within water‐in‐oil‐in‐water double emulsion droplets, generated at high frequency. Within each droplet, the peptides can interact with different classes of co‐encapsulated liposomes, generating a membrane‐specific fluorescent signal. The double emulsions can be incubated and observed in a hydrodynamic trapping array or analyzed via flow cytometry. Our approach provides a valuable tool for the discovery and development of membrane‐active antimicrobials.
Anterior segment optical coherence tomography imaging and ocular biometry in cataract patients with open angle glaucoma comorbidity (2021)

Cataract patients tend to develop narrow anterior chamber angles. Anterior chamber angle parameters have a positive moderate to strong relationship with lens position. LP may be used predicting narrow angles.
Prognostic significance of aortic valve gradient in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (2017)

Baseline AVGs show an inverse association with mortality post-TAVR. These results were consistent also in patients with high-gradient AS, suggesting that AVG can be used to identify patients most likely to benefit from TAVR.
Light scattering from dislocations in silicon (2010)

Nondecorated glide dislocations in Czochralski grown silicon have been studied by laser scattering tomography technique. Dependence of intensity of scattered light on polarization of the incident light has been measured for different orientations of the dislocation line and Burgers vector. Detailed theory of light scattering by dislocation in silicon crystals is presented. It is shown that by combination of polarization and tomography measurements it is possible to determine slip system of nondecorated mixed dislocation in Si.
Multiple Myeloma (2011)

Multiple myeloma (MM) is a malignant neoplasm of plasma cells that accumulate in bone marrow, leading to bone destruction and marrow failure. The American Cancer Society estimates 20,520 new cases of MM will be diagnosed in the United States in 2011, including 11,400 cases in men and 9,120 in women, with an estimated 10,610 deaths. The treatment of MM has dramatically improved over the past decade. The 5-year survival rate reported in the Surveillance, Epidemiology and End Results database increased from 25% in 1975 to 34% in 2003 because of newer and more effective treatment options. 2,
A Clinical and Immunological Study of Allergy to Hen's Egg White (1983)

Antigen 22 (ag-22) in hen's egg white, previously shown to be one of the major allergens in the egg white, was partially purified by combining biochemical separation techniques and quantitative immunoelectrophoretic methods. The molecular weight of ag-22 was found to be approximately 78,000 using analytical ultracentrifugation and pI was determined to be 6.1, which is appropriate with the values of ovotransferrin. It was concluded that ag-22 is identical with ovotransferrin. The ability of ovotransferrin to react in the human IgE-system was demonstrated in vivo and in vitro, by means of skin prick tests and crossed radioimmunoelectrophoresis.
Probing of Cu presence at Ta-SiO/sub 2/ interfaces by second harmonic generation measurement (2005)

In this paper, we have demonstrated for the first time that optical second harmonic generation (SHG) measurement can be used to probe Cu presence at the Ta-SiO/sub 2/ interfaces. We report here the details of our experimental procedures and investigation results. This technique shows tremendous potential in surface and interface microanalysis for Cu presence at these regions.
BCL3 (Books for College Libraries) and the Book Jobber: The Marketing of a New Collection Development Service (2019)

When the third edition of Books for College Libraries (BCL3) was released in 1988, it was available for the first time in a machine-readable format. At Midwest Library Service, the decision was made to obtain the tapes of BCL3 and investigate their possible application as a collection development tool which could be used to compare a library’s holdings as reflected in their OCLC records to the idealized collection as reflected in BCL3. The hope was that this service would result in an increase of book orders for Midwest through both routine library expenditures as well as potential grants which this sort of project might engender. Several problems, some expected, some unexpected arose as this new service went into testing, but the early results suggest the viability of the project if potential clients are strictly qualified.

Cerebral Oximetry During Infant Cardiac Surgery: Evaluation and Relationship to Early Postoperative Outcome (2009)

Intraoperative rSO(2) varies according to anatomic diagnosis but accounts for very little of the variance in early outcome. As measured by frontal near-infrared spectroscopy, higher levels of hematocrit and current perfusion techniques appear to provide an adequate oxygen reservoir prior to relatively short periods of DHCA.
Annexin A10 meets the challenge of differentiating intrahepatic cholangiocarcinoma from metastatic pancreatic ductal adenocarcinoma. A comparative study of immunohistochemical markers (2016)

Aims: Discriminating intrahepatic cholangiocarcinoma (ICC) from hepatic metastases of pancreatic ductal adenocarcinoma (mPDAC) can be challenging. While pathologists still depend on clinicians' anamnestic readings about primary tumor, their diagnosis will lead the patient either to possibly curative operation (for ICC) or to palliation (for mPDAC). Beyond the validation of recently published potential biomarkers for PDAC (primary or metastatic) in a large cohort, we assessed the diagnostic performance of the most promising candidates in the challenging task of discriminating metastatic PDAC (mPDAC) and ICC.
Page-based optimistic concurrency control for memory-mapped persistent object systems (2002)

New applications that support cooperative work of users on distributed computers often share persistent data structures that contain pointers. For these applications, the underlying system, often uses the "page server" architecture, in which the persistent data are shipped from the server on a page basis, and clients cache the pages for object-grain accesses. In this page-grain environment, conventional concurrency control schemes do not work as well as they do in the object-grain environment for business applications, because of their lack of efficiency and/or correctness. The two-phase locking scheme and timestamp ordering scheme suffer from frequent lock contention, (false) deadlocks, and/or frequent transaction restarts. Existing optimistic schemes sometimes provide inconsistent views of the persistent storage to transactions that are to be aborted. This paper proposes a novel concurrency control scheme. Called "page-based versioned optimistic" scheme. suitable for serialization of distributed cooperative applications with page-grain accesses. The optimistic scheme with versioning avoids lock contention, commits all read-only transactions, and provides consistent views of the persistent storage even to transactions that are to be aborted. The scheme is able to be implemented efficiently in distributed systems as well as in centralized systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
An Observational Case for the Prevalence of Roll Vortices in the Hurricane Boundary Layer* (2005)

Abstract Doppler velocity data from Weather Surveillance Radar-1988 Doppler (WSR-88D) radars during four hurricane landfalls are analyzed to investigate the presence of organized vortices in the hurricane boundary layer (HBL). The wavelength, depth, magnitude, and track of velocity anomalies were compiled through analysis of Doppler velocity data. The analysis reveals alternating bands of enhanced and reduced azimuthal winds closely aligned with the mean wind direction. Resulting statistics provide compelling evidence for the presence of organized secondary circulations or boundary layer rolls across significant areas during four hurricane landfalls. The results confirm previous observations of the presence of rolls in the HBL. A potential limitation of the study presented here is the resolution of the WSR-88D data. In particular, analysis of higher-resolution data (e.g., from the Doppler on Wheels) is needed to confirm that data aliasing has not unduly impacted the statistics reported here. Momentum fluxes associated with the secondary circulations are estimated using the covariance between the horizontal and vertical components of the wind fluctuations in rolls, with resulting fluxes 2–3 times greater than estimated by parameterizations in numerical weather prediction models. The observational analysis presented here, showing a prevalence of roll vortices in the HBL, has significant implications for the vertical transport of energy in hurricanes, for the character of wind damage, and for improvements in numerical simulations of hurricanes.

Relationship between maternal environment and DNA methylation patterns of estrogen receptor alpha in wild Eastern Bluebird (Sialia sialis) nestlings: a pilot study (2016)

There is mounting evidence that, across taxa, females breeding in competitive environments tend to allocate more testosterone to their offspring prenatally and these offspring typically have more aggressive and faster-growing phenotypes. To date, no study has determined the mechanisms mediating this maternal effect's influence on offspring phenotype. However, levels of estrogen receptor alpha (ER α) gene expression are linked to differences in early growth and aggression; thus, maternal hormones may alter gene regulation, perhaps via DNA methylation, of ER α in offspring during prenatal development. We performed a pilot study to examine natural variation in testosterone allocation to offspring through egg yolks in wild Eastern Bluebirds (Sialia sialis) in varying breeding densities and percent DNA methylation of CG dinucleotides in the ER α promoter in offspring brain regions associated with growth and behavior. We hypothesized that breeding density would be positively correlated with yolk testosterone, and prenatal exposure to maternal-derived yolk testosterone would be associated with greater offspring growth and decreased ER α promoter methylation. Yolk testosterone concentration was positively correlated with breeding density, nestling growth rate, and percent DNA methylation of one out of five investigated CpG sites (site 3) in the diencephalon ER α promoter, but none in the telencephalon (n = 10). Percent DNA methylation of diencephalon CpG site 3 was positively correlated with growth rate. These data suggest a possible role for epigenetics in mediating the effects of the maternal environment on offspring phenotype. Experimentally examining this mechanism with a larger sample size in future studies may help elucidate a prominent way in which animals respond to their environment. Further, by determining the mechanisms that mediate maternal effects, we can begin to understand the potential for the heritability of these mechanisms and the impact that maternal effects are capable of producing at an evolutionary scale.
Mit Peptiden dekorierte Dendrimere und ihre biotechnologische Nutzung (2016)

Abstract Peptid‐dekorierte Dendrimere (PDDs) bilden eine Klasse kugelförmiger, regulärer, verzweigter Polymere, die an ihren Oberflächen kovalent durch Peptide modifiziert sind. PDDs sind als Proteinmimetika, neuartige Biomaterialien sowie für ein breites Spektrum biomedizinischer Anwendungen zum Einsatz gekommen. Seit ihrer Konzeption und Entwicklung in den späten 1980er Jahren ist Poly‐ l ‐lysin die bevorzugte Kernstruktur für PDDs. Jüngst haben zahlreiche Innovationen in der Polymer‐ und Ligationschemie das Feld neu belebt. Dies hat dazu geführt, dass heute wohldefinierte Dendrimere mit vielfältigeren Strukturen und Funktionen vorliegen. Dieser Kurzaufsatz beleuchtet die Entwicklung von PDDs als Produkte einer signifikant verbesserten Ligationschemie unter Einbeziehung strukturell wohldefinierter Peptide sowie erste Anwendungen von PDDs in den Bereichen Bildgebung und Wirkstoffentwicklung.
Bioavailability of Ginsenosides from White and Red Ginsengs in the Simulated Digestion Model (2014)

This study aims to investigate the bioavailability of ginsenosides during simulated digestion of white (WG) and red (RG) ginseng powders. Stability, bioaccessibility, and permeability of ginsenosides present in WG and RG were studied in a Caco-2 cell culture model coupled with oral, gastric, and small intestinal simulated digestion. Most ginsenosides in WG and RG were stable (>90%) during the simulated digestion. Bioaccessibilities of total ginsenosides during in vitro digestion of WG and RG were similar at approximately 85%. However, the bioaccessibility of protopanaxatriol type ginsenosides in the early food phase was greater than that of the protopanaxadiol type. The less polar RG ginsenosides were released later following the jejunum phase. Ginsenosides had low permeability (<1 × 10(-6) cm/s) through Caco-2 cell monolayers. These findings suggest that the WG and RG ginsenoside compositions affect bioaccessibility during digestion and that ginsenosides are poorly absorbed in humans.
Sorption of Alcohol−Toluene Mixtures in Poly(acrylic acid)−Poly(vinyl alcohol) Blend Membranes and Its Role on Pervaporation (1998)

The overall and preferential sorption of alcohol−toluene mixtures in homogeneous blends of poly(acrylic acid) and poly(vinyl alcohol) were determined. Both the overall solubility and the equilibrium sorption selectivity were strongly dependent on the composition of the blend and of the liquid feed mixture. The swelling of the blends increased with increasing poly(acrylic acid) content and with increasing alcohol content in the liquid mixtures. Alcohols were sorbed preferentially over toluene in all cases tested. The equilibrium sorption selectivity increased with increasing poly(vinyl alcohol) content in the blends and with decreasing alcohol content in the liquid mixtures. The equilibrium sorption selectivity was predicted by a model which was derived from Flory−Huggins thermodynamics. The agreement between the predicted and the experimental results was very good. In addition, the equilibrium sorption results were compared with the pervaporation results, and this clearly shows that preferential sorption dominates the pervaporation selectivity in the systems studied.

We also discuss an anesthetic/surgical approach on how to provide maximum analgesia with minimal anesthesia.
Efficient arbitrary simultaneously entangling gates on a trapped-ion quantum computer (2020)

Efficiently entangling pairs of qubits is essential to fully harness the power of quantum computing. Here, we devise an exact protocol that simultaneously entangles arbitrary pairs of qubits on a trapped-ion quantum computer. The protocol requires classical computational resources polynomial in the system size, and very little overhead in the quantum control compared to a single-pair case. We demonstrate an exponential improvement in both classical and quantum resources over the current state of the art. We implement the protocol on a software-defined trapped-ion quantum computer, where we reconfigure the quantum computer architecture on demand. Our protocol may also be extended to a wide variety of other quantum computing platforms.
Inhibition of growth factor effects in retinal pigment epithelial cells. (1991)

Several agents were examined for their effect on growth factor-stimulated processes in retinal pigment epithelial (RPE) cells. DNA synthesis was assessed by 3H-thymidine incorporation in density-arrested cells using previously determined maximally effective concentrations of various growth factors with and without test substances. Cell migration was assessed in Boyden chamber assays. For each test substance, trypan blue exclusion was used to determine noncytotoxic concentrations, and the effect of several concentrations were assessed on selected growth factors. The most effective, nontoxic concentration was then used for comparisons. Two cationic proteins, protamine and histone type II B, caused inhibition of RPE chemotaxis and 3H-thymidine incorporation induced by several growth factors, but a cationic polypeptide, polylysine, did not. Protamine and histone, were particularly effective inhibitors of acidic and basic fibroblast growth factors (FGF) but not if they were exposed to cells and then removed before growth factor addition. They had no effect on serum-stimulated chemotaxis or 3H-thymidine incorporation even when used in the presence of serum. Three anionic substances, heparin, pentosan polysulfate, and suramin, also inhibited RPE chemotaxis and 3H-thymidine incorporation induced by several different growth factors. They were less effective inhibitors of the FGFs than protamine and histone but were better inhibitors of serum-induced effects. Also unlike protamine and histone, the anionic substances maintained their inhibitory effect even when removed before growth factor addition. Since migration and proliferation of RPE cells are important processes in the pathogenesis of proliferative vitreoretinopathy, these agents and their mechanism of action deserve further study for potential therapeutic applications.
