Effects of mesozooplankton removal and ammonium addition on planktonic trophic structure during a bloom of the Texas 'brown tide': a mesocosm study (2003)

A bloom of the alga Aureoumbra lagunensis, known as the Texas ‘brown tide’, persisted in the Laguna Madre of Texas for most of the 1990s. The dominant mesozooplankter in Laguna Madre, Acartia tonsa, does not feed on A. lagunensis, and during blooms there are few other suitably sized phytoplankton cells available to feed on. We hypothesized that these copepods increased their feeding on microzooplankton, thereby reducing grazing pressure by microzooplankton on A. lagunensis and contributing to the persistence of this bloom. A mesocosm experiment was carried out to test this hypothesis during the summer of 1999. Twelve fiberglass corral-type mesocosms were deployed in the field for 16 days, each enclosing ∼1.2 m3 of Laguna Madre water and 1.1 m2 of natural benthos. Mesozooplankton were removed from six mesocosms with a 153 μm mesh dip net every 4 days; the other six mesocosms were treated in the same way, except that the contents of the net were returned to the mesocosm. For each zooplankton treatment, half of the mesocosms were dosed with ∼40 μm NH4 at 4 day intervals, and half received no additions. Phytoplankton populations in these mesocosms at the start of the experiment were dominated by A. lagunensis and the cyanobacterium Synechococcus spp. Growth rates of A. lagunensis were higher in mesocosms without ammonium additions, providing no evidence for nitrogen limitation. Acartia tonsa populations were reduced by ∼50% in the zooplankton removal mesocosms, and ciliate populations were significantly higher. The increase in ciliate population had no significant impact on A. lagunensis population dynamics, however, providing no evidence to support the hypothesis that a trophic cascade reducing microzooplankton populations contributed to the persistence of the brown-tide bloom. In contrast, populations of Synechococcus sp. showed evidence of both ‘top–down’ and ‘bottom–up’ control; they grew faster in nutrient addition mesocosms and had lower populations in mesocosms with increased densities of ciliate grazers.

Kinetics of Binding of Carrier-Free Ga-67 to Human Transferrin (1978)

A new method has been developed for calculation of a relative intrinsic association constant, K, for the binding of carrier-free gallium-67 to human transferrin. The approach is based on the method of Scatchard, and depends on the relatively large molar abundance of transferrin compared with the molar concentration of carrier-free Ga-67. Values obtained are in the range of K = 2.5 x 10/sup 5/ liters/mol.

ESTIMATIVA DO CRESCIMENTO DE POVOAMENTOS DE Eucalyptus\t BASEADA NA\nTEORIA DOS MODELOS NÃO LINEARES EM MULTINÍVEL DE EFEITO MISTO (2005)

O presente estudo foi baseado na utilização da teoria dos\nmodelos não-lineares de efeito misto em multiníveis para a\nmodelagem do crescimento em altura de povoamentos clonais de\nEucalyptus. A base de dados utilizada representa medições de\nárvores individuais, tomadas em diferentes locais e no tempo,\nsendo a mesma classificada de longidudinal, irregularmente\nespaçada, não-balanceada, com autocorrelação e com\na presença de heterogeneidade de variância. O modelo\nlogístico de três parâmetros foi utilizado para a\nestimativa do crescimento em altura. Os parâmetros do modelo foram\nestimados como de efeitos fixos e aleatórios em dois níveis:\nunidade amostral (nível 1) e árvore individual dentro das\nunidades amostrais (nível 2). A inclusão de tais níveis\nreduziu sensivelmente o erro padrão da estimativa para o modelo.\nAs estimativas também foram melhoradas com a modelagem da\nheterogeneidade da variância, utilizando estruturas diagonais, e\nda autocorrelação, com a estrutura ARMA(2,1).

Ignition of boron particles coated by a thin titanium film (1993)

A theoretical model for the ignition of titanium-coated boron particles in dry air has been developed. In general, the results indicate reduction in ignition time due to a high heating rate of the particle resulting from the reactions of titanium with both boron and oxygen and the deterioration of the protective properties of the coating layers due to mechanical stresses. However, ignition strongly depends on the titanium coating thickness and the ambient temperature.

Priming of Darkness-Rewarded Runway Responses in the American Cockroach (<i>Periplaneta Americana</i>) (1981)

Summary After cockroaches were trained to traverse an illuminated runway with darkness as the rewarding event, they were given brief “primes” of darkness in the startbox. Runway performance was enhanced, but these priming effects declined as postprime delay (i.e., the delay before a roach was permitted to leave the startbox) was increased. A second experiment found that the response enhancement was greater after primes of long duration than after primes of short duration. The present work suggests a possible distinction between the priming properties of food and water on the other hand, and darkness, brain stimulation, and an imprinting object on the other.
Correlation between calcific aortic stenosis diagnosed by two‐dimensional echocardiography and cardiac catheterization (1984)

This retrospective study correlates the severity of calcific aortic stenosis determined by two-dimensional (2-D) echocardiography with the aortic valve area determined by catheterization in 57 patients. Aortic valve leaflet calcification was diagnosed by cineangiography in 50 (88%) of 57 patients and by 2-D echo in 57 (100%) of 57 patients (p less than 0.025). An agreement between severity of aortic stenosis by catheterization and 2-D echo occurred in 22 (39%) of 57 patients. Chi-square and logistic regression analyses showed no correlation between the severity of aortic stenosis and the 2-D echo variables: left ventricular wall thickness, left ventricular diastolic dimension, left ventricular systolic dimension, aortic root diameter, and left atrial dimension. We conclude that 2-D echo detects aortic leaflet calcification better than cineangiography. However, the severity of aortic stenosis determined by 2-D echo correlates poorly with the severity of aortic stenosis determined by cardiac catheterization.
Wavelet based channel model for OFDM systems (2005)

In this paper, we present first ideas on how highly time and frequency selective channels may be modeled using wavelet decomposition. This approach is compared to a previously developed channel model using Karhunen-Loeve decomposition. We focus our study on OFDM systems, but this means no restriction with respect to the application of such a modeling technique.
A CD4-independent interaction of human immunodeficiency virus-1 gp120 with CXCR4 induces their cointernalization, cell signaling, and T-cell chemotaxis. (1999)

The gp120 envelope glycoprotein of human immunodeficiency virus-1 (HIV-1) interacts with the CXCR4 chemokine receptor, but it is not known whether gp120 activates CXCR4-mediated signaling cascades in the same manner as its natural ligand, SDF1alpha. We assessed the effects of wild-type gp120 and a mutant gp120 that interacts with CXCR4 but not CD4 on CD4(-)/CXCR4(+) cells and CD4(+)/CXCR4(+) cells, respectively. Under both experimental conditions, the interaction of CXCR4 and gp120 resulted in their CD4-independent cointernalization. Both molecules were translocated into early endosomes, whereas neither protein could be detected in late endosomes. Binding of gp120 to CXCR4 resulted in a CD4-independent phosphorylation of Pyk2 and an induction of chemotactic activity, demonstrating that this interaction has functional consequences. Interestingly, however, whereas SDF1alpha activated the ERK/MAP kinase pathway, this cascade was not induced by gp120. Together, these results suggest that the pathology of HIV-1 infection may be modulated by the distinct signal transduction pathway mediated by gp120 upon its interaction with CXCR4.
Ultrasonic Wall Thickness Monitoring at High Temperatures (>500°C) (2011)

Corrosion and erosion shorten the life of components that are used in the petrochemical industry. In order to mitigate the safety and financial risks posed by the degradation mechanisms, plant operators monitor wall thicknesses at regular inspection intervals. In high temperature locations inspections have to be carried out at plant shut downs because conventional ultrasonic sensors cannot withstand the high operating temperatures. The authors have developed a waveguide based high temperature thickness gauge for monitoring of wall thicknesses in high temperature areas. The waveguide allows the use of conventional transduction systems (max temp. 60°C) at one end and guides ultrasonic waves into the high temperature region where the inspection is to be carried out. Slender stainless steel waveguides allow a temperature drop of ~500-600°C per 200mm length to be sustained simply by natural convection cooling. This paper describes the technical challenges that had to be overcome (dispersion and source/receiver characteristics) in order to implement this “acoustic cable”. A commercial system for wireless corrosion monitoring based on the technology is now available. Experimental results of thickness measurements on components of different thickness, furnace tests at different temperatures and accelerated corrosion tests are presented as well as data from sensors that have been installed in petrochemical plants. In addition to this it is demonstrated how trending and multiple repeat measurements allow extraction of more information from the measured data.
Increased “Glucagon Immunoreactivity” in Plasma of Totally Depancreatized Dogs (1974)

Elevated plasma glucagon immunoreactivity (IRG) observed in overt diabetes and during prolonged fasting is assumed to be the result of increased secretion of pancreatic glucagon. In seven healthy mongrel dogs diabetes was induced by total pancreateetomy During the first two weeks following surgery, porcine NPH (6 to 12 U, once daily) and Regular insulin (6 to 12 U twice daily) were administered. Thereafter, insulin treatment was discontinued and the dogs were fasted for periods up to seven days. Plasma IRG was measured using antiglucagon serum G9-I which is 95 per cent specific for pancreatic glucagon. Fifteen hours after the last insulin injection an intraportal infusion of Regular insulin was given in amounts sufficient to achieve normoglycemia: mean IRG (pg./ml.) was 118 ± 34, a value similar to that observed in the fasting intact animals (134 ± 33). After insulin withdrawal, as fasting continued, plasma IRG increased progressively in all dogs. On Days 5 and 6-7, after insulin withdrawal, when peripheral plasma insulin was undetectable and marked hyperglycemia, hyperlipacidemia and ketonuria prevailed, mean IRG was 624 ± 136 and 986 ±184, respectively. The highest level of IRG observed was 1450 in one dog on Day 7. These results are confirmed by using three other antiglucagon sera considered to be specific for pancreatic glucagon. We conclude that: 1) Progressively increasing amounts of material crossreacting with “specific” antiglucagon sera appear in plasma of totally depancreatized dogs fasting for up to seven days. 2) This event appears to be the consequence of metabolic derangements induced by insulin lack. 3) Hyperglucagonemia can result onoly from a defect of the pancreatic α cell, but can also be the consequence of excessive production of IRG from a nonpancreatic source. It could be that glucagon deficiency cannot be easily demmonstrated, because the release of nonpancreatic IRG can compensate for lack of pancreatic glucagon.

Effect of Centrifugal Distortion on Line Intensities in Asymmetric-Rotor Molecules (1970)

A general theoretical treatment of intensity perturbations due to centrifugal distortion is given for the vibration–rotation lines of asymmetric-rotor molecules. The present theory gives the intensity perturbations up to the second order. By use of empirical constants, the theory is applied to the ν2 band of H2O and good agreement is obtained with experimental results of various authors.

A soft image edge detection approach based on the time matrix of a PCNN (2008)

Image segmentation has attracted the attention of researcher for many decades. Different approaches have been developed in order to find the solution in many different segmentation situations. In this paper we propose a novel edge detection approach aimed to generate useful information to achieve segmentation. The proposed method is based on analysis of the information provided by the time matrix generated from a pulse coupled neural network, PCNN. This information represents gray level differences among the pixel images. Two different schemes for edge detection are presented. The first scheme is developed to generate edges from coarse images and the second one to deal with more detailed edges. Similarity of this method with a previous developed method based on fuzzy edge level detection is also covered in the paper. Final results show that the proposed method may be used as a new alternative to define image edges of different levels for further analysis.
Power-insensitive silicon crystal-cut for amplitude-stable frequency synthesis (2017)

This paper reports on the theoretical prediction and experimental verification of the existence of a power-insensitive crystal cut in doped single crystal silicon (SCS). The existence of such a cut enables fully harmonic excitation of extensional elastic waves with negligible dispersion. Aligning bulk acoustic resonators to this power-insensitive cut along with suppression of boundary-induced nonlinearities enable realization of vibration-amplitude insensitive frequency references. An analytical formulation is presented to characterize the anisotropic anharmonic behavior of SCS elasticity, predicting the existence of the power-insensitive cut at ~30° offset from <;100> axis. This prediction is experimentally verified through implementation and characterization of an array of waveguide-based resonators aligned to different crystallographic directions. The resonators are optimized for substantial suppression of boundary induced nonlinearities through dispersive energy trapping technique. Among these, the waveguide-based resonator aligned to 22.5° cut shows a 1-dB compression point at 29dBm, which is 50× higher power-handling compared to <;100>/<;110> counterparts. Dispersive energy trapping used for elimination of geometrical nonlinearities simultaneously realizes a high Q of ~7,000 at 80MHz, which is independent of the crystallographic orientation.
Neutralizing Antibody-Resistant Hepatitis C Virus Cell-to-Cell Transmission (2010)

Hepatitis C virus (HCV) can initiate infection by cell-free particle and cell-cell contact-dependent transmission. In this study we use a novel infectious coculture system to examine these alternative modes of infection. Cell-to-cell transmission is relatively resistant to anti-HCV glycoprotein monoclonal antibodies and polyclonal immunoglobulin isolated from infected individuals, providing an effective strategy for escaping host humoral immune responses. Chimeric viruses expressing the structural proteins representing the seven major HCV genotypes demonstrate neutralizing antibody-resistant cell-to-cell transmission. HCV entry is a multistep process involving numerous receptors. In this study we demonstrate that, in contrast to earlier reports, CD81 and the tight-junction components claudin-1 and occludin are all essential for both cell-free and cell-to-cell viral transmission. However, scavenger receptor BI (SR-BI) has a more prominent role in cell-to-cell transmission of the virus, with SR-BI-specific antibodies and small-molecule inhibitors showing preferential inhibition of this infection route. These observations highlight the importance of targeting host cell receptors, in particular SR-BI, to control viral infection and spread in the liver.
