Vocalization source level distributions and pulse compression gains of diverse baleen whale species in the Gulf of Maine (2016)

The vocalization source level distributions and pulse compression gains are estimated for four distinct baleen whale species in the Gulf of Maine: blue, fin, minke, and sei. The vocalizations were received on a large-aperture densely sampled coherent hydrophone array system deployed to monitor marine mammals over instantaneous wide areas using the passive ocean acoustic waveguide remote sensing technique. For each baleen whale species, between 400 to over 1400 measured vocalizations with significantly high signal-to-noise ratios (SNR&gt;10 dB) after coherent beamforming and localized with high accuracies (&lt;10% localization errors) over ranges spanning roughly 1 km to 38 km are included in the analysis. The whale vocalization received pressure levels are corrected for broadband transmission losses modelled using a calibrated parabolic equation based acoustic propagation model for a random range-dependent ocean waveguide. The broadband vocalization equivalent pulse-compression gains are found to be 2.5±1.1 for fin, 24±10 for blue, and 69±23 for sei. The source level distributions and pulse compression gains are essential for determining signal-to-noise ratios and hence detection regions for baleen whale vocalizations received passively on underwater acoustic sensing systems, as well as for assessing communication ranges and potential for echolocation in baleen whales.

The helicity dependence of the $\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\gamma}}\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\rightarrow}p{\ensuremath{\pi}}^{0}$ reaction has been measured for the first time in the photon-energy range from 550 to 790 MeV. The experiment, performed at the Mainz microtron MAMI, used a $4\ensuremath{\pi}$-detector system, a circularly polarized, tagged photon beam, and a longitudinally polarized frozen-spin target. These data are predominantly sensitive to the ${D}_{13}(1520)$ resonance and are used to determine its helicity amplitudes.
Optimal Stopping Times for Detecting Changes in Distributions (1986)

It is shown that Page's stopping time is optimal for the detection of changes in distributions, in a well defined sense. This work is a generalization of an existing result where it was shown that Page's stopping time is optimal asymptotically.
Performance evaluation of a two-phase commit based protocol for DDBs (1982)

Many concurrency control algorithms for distributed database management systems have been proposed in the last few years, but little has been done to analyse their performance. This paper presents the specification of a concurrency control algorithm based on the two-phase commit protocol for DDBs. The results of a complete performance analysis based on an analytic model are presented and discussed.
Highly Stereoselective Tandem Aza‐Michael Addition–Enolate Protonation to Form Partially Modified Retropeptide Mimetics Incorporating a Trifluoroalanine Surrogate (2003)

Fine-tuning of key reaction parameters, such as the solvent and the base used, led to a dramatic improvement in d.r. (from ≈1:1 to 38:1) in a tandem aza-Michael addition–enolate protonation sequence. Thus, the reaction of α-amino ester nucleophiles 1 with N-(α-trifluoromethyl)acryloyl-α-amino ester acceptors 2 produced an array of partially modified retropeptide mimetics 3 with good to excellent stereocontrol (R, R1, R2, X, X1=alkyl).

Synthesis of [2-11C]5,5-dimethyl-2,4-oxazolidinedione for studies with positron tomography. (1982)

We have developed a method for the synthesis of [2-11C]5,5-dimethyl-2,4-oxazolidinedione ([2-11C]DMO) for use with positron emission tomography to measure regional tissue pH in vivo in man. [2-11C]Dimethyl carbonate (DMC) was prepared from [C-11]phosgene and excess of sodium methoxide in methanol containing dimethyl carbonate as added carrier. The [2-11C]DMC solution was then reacted with 2-hydroxyisobutyramide at 150 degrees C for 10 min to yield, after HPLC separation, [2-11C]DMO with a radiochemical yield of 20-56%. Chemical yields were 78-92%, and specific activity ranged as high as 830 mCi/millimol.

Determination of Pyridostigmine in Mammalian Plasma: Addressing Current Problems (1986)

Abstract The variable data for pyridostigmine levels reported in human plasma would indicate procedural and/or analytical problems. Consequently an effort was made to establish a precise and sensitive method which could be applied to the quantitation of pyridostigmine in plasma of human as well as other mammalian species. In this method the effect of various types of anticoagulants, the efficacy and precision of the isolation cartridge, the stability of the drug in blood, and the effect of cryogenic storage on the isolation and quantitation of both drug and internal standard were examined. Data on spiked human, guinea pig, dog, and rat plasma at nanogram level of pyridostigmine were presented. Variable concentrations of mobile phase, ranging from 20–27% acetonitrile in water, were used to minimize interfering peaks present in blank samples. Limits of sensitivity in ng/ml (CV) were: human, 2.5 (12.5%), guinea pig, 5.0 (4.5%), dog, 5.0 (2.7%), and rat, 5.0 (7.2%).
Gaussian process analysis of Electron Energy Loss Spectroscopy (EELS) data: parallel reconstruction and kernel control (2020)

Advances in hyperspectral imaging modes including electron energy loss spectroscopy (EELS) in scanning transmission electron microscopy (STEM) bring forth the challenges of exploratory and subsequently physics-based analysis of multidimensional data sets. The (by now common) multivariate unsupervised linear unmixing methods and their nonlinear analogs generally explore similarities in the energy dimension but ignore correlations in the spatial domain. At the same time, Gaussian process (GP) methods that explicitly incorporate spatial correlations in the form of kernel functions tend to be extremely computationally intensive, while the use of inducing point-based sparse methods often leads to reconstruction artefacts. Here, we suggest and implement a parallel GP method operating on the full spatial domain and reduced representations in the energy domain. In this parallel GP, the information between the components is shared via a common spatial kernel structure while allowing for variability in the relative noise magnitude or image morphology. We explore the role of common spatial structures and kernel constraints on the quality of the reconstruction and suggest an approach for estimating these factors from the experimental data. Application of this method to an example EELS dataset demonstrates that spatial information contained in higher-order components can be reconstructed and spatially localized. This approach can be further applied to other hyperspectral and multimodal imaging modes. The notebooks developed in this manuscript are freely available as part of a GPim package (https://github.com/ziatdinovmax/GPim).
Development of a laser scribing process of coated conductors for the reduction of AC losses (2007)

Expectations are high for using coated conductors for electric power applications not only because of better cost performance but also higher Jc–B properties compared with Bi2Sr2Ca2Cu3O10 (BSCCO) tapes. Furthermore, the coated conductors could also reduce AC losses by the use of various methods in post-treatment. When a YAG laser was used for scribing the superconductive layer, an AC loss reduction due to a decrease in the width of the superconductivity layer could be confirmed in short samples.
Rate-Equivocation Optimal Spatially Coupled LDPC Codes for the BEC\n Wiretap Channel (2010)

We consider transmission over a wiretap channel where both the main channel\nand the wiretapper's channel are Binary Erasure Channels (BEC). We use\nconvolutional LDPC ensembles based on the coset encoding scheme. More\nprecisely, we consider regular two edge type convolutional LDPC ensembles. We\nshow that such a construction achieves the whole rate-equivocation region of\nthe BEC wiretap channel.\n Convolutional LDPC ensemble were introduced by Felstr\\"om and Zigangirov and\nare known to have excellent thresholds. Recently, Kudekar, Richardson, and\nUrbanke proved that the phenomenon of "Spatial Coupling" converts MAP threshold\ninto BP threshold for transmission over the BEC.\n The phenomenon of spatial coupling has been observed to hold for general\nbinary memoryless symmetric channels. Hence, we conjecture that our\nconstruction is a universal rate-equivocation achieving construction when the\nmain channel and wiretapper's channel are binary memoryless symmetric channels,\nand the wiretapper's channel is degraded with respect to the main channel.\n
A Decision-Analysis Framework to Support Risk Assessment for Geologic Radioactive Waste Disposal Systems (2008)

Safety assessments for geologic radioactive waste disposal systems involve risk assessments that 
cover many topics within a wide range of technical disciplines. Priorities should be set for 
investigating these topics to ensure that the most important aspects of the repository behavior are 
well understood. This paper presents a decision-analysis framework designed to support such risk 
assessments by identifying important issues upon which to focus technical work. Key attributes of 
this framework are (i) an analytical procedure that integrates risk perception with technical 
evidence, (ii) an algorithm that does not involve execution of a mathematical simulation model, 
and (iii) a set of metrics that indicate the important technical issues for the risk assessments. A 
demonstration of the decision-analysis framework on a hypothetical geologic repository highlights 
the joint impact of perception and evidence on decisions that inform priorities for advancing 
technical work and building confidence in projections of future behavior for radioactive waste 
disposal systems. Potential applications to other systems analyses are discussed.
Weak intermolecular interactions in isomorphous 5-(2-chloroethoxy)-2,3-dihydro-1,4-benzodioxine and 5-(2-bromoethoxy)-2,3-dihydro-1,4-benzodioxine: bonding or nonbonding interactions (2009)

The title compounds, C10H11ClO3, (I), and C10H11BrO3, (II), are isomorphous and effectively isostructural; all of the interatomic distances and angles are normal. The structures exhibit long intermolecular C-H...O and C-H...pi contacts with attractive energies ranging from 1.17 to 2.30 kJ mol(-1). Weak C-H...O hydrogen bonds form C(3) and C(4) motifs, combining to form a two-dimensional R(3)(4)(12) net. No face-to-face stacking interactions are observed.
Eye movements and neural remapping during fusion of misaligned random-dot stereograms (1983)

Fender and Julesz [ J. Opt. Soc. Am.57, 819 ( 1967)] found that fused retinally stabilized binocular line targets could be misaligned on the two retinas in the temporalward direction by at least 30 min of arc without loss of fusion and stereopsis and that random-dot stereograms could be misaligned 2 deg before fusion was lost. To test these results in normal vision, we recorded eye motions of four observers while they viewed a random-dot stereogram that subtended about 10 deg. The observers misaligned overlaid vectograph stereo images by moving them apart in a temporalward direction until fusion was lost. They then returned the vectographs to the overlaid position. Throughout this cycle the observers reported at frequent intervals if they could perceive strong or weak depth, loss of depth, or loss of fusion. For some observers the image separation could be increased to 5 deg beyond parallel before fusion was lost. The visual axes diverged to follow the image centers and varied from overconverged to overdiverged with respect to the image centers while the observers still reported depth and fusion. We call the difference between the image separation and eye vergence the vergence error. If a vergence error persisted for at least 10 sec without loss of the percepts of fusion and depth, we postulate that neutral remapping occurred that compensated for the retinal misalignment. We found that the average maximum neural remapping was 3.0 deg. The neural remapping was greater at loss of fusion than at regaining fusion. This phenomenon corresponds to the hysteresis measured by Fender and Julesz. We obtained an average hysteresis value of 2.6 deg with a maximum value of 4.1 deg. The average value is somewhat larger than the value reported by Fender and Julesz; this might result from our use of larger targets. We recorded many vergence saccades, in both the convergent and divergent directions, associated with scanning the target. Refusion occurred after the images were briefly aligned on the retinas by a pair of vergence saccades. These saccades were initiated when the vergence error returned to the value that it had when fusion was lost, and the magnitude of the divergent saccade was such that the vergence error was reduced to zero. This may imply retention of the position of correspondence that spanned a period of nearly 1 min between loss and restoration of fusion.

Investigation of electrical shading effects in back-contacted back-junction silicon solar cells using the two-dimensional charge collection probability and the reciprocity theorem (2011)

In this study, short-circuit current losses in high-efficiency n-type back-contacted back-junction silicon solar cells caused by the electrical shading effect have been investigated by two-dimensional simulations of the charge carrier collection probability. Based on the reciprocity theorem, the homogenous partial differential equation describing the probability of charge carriers being collected by the p-n junction on the rear side of the solar cell has been solved numerically using the finite element method implemented in the partial differential equation solver COMSOL Multiphysics. The method has been applied to study the impact of geometrical parameters of the solar cell, such as the pitch distance, as well as the emitter and back surface field width, on the local and global internal quantum efficiency and on the short-circuit current density. The influence of the rear surface recombination velocity of an undiffused gap and the effective rear surface recombination velocity of the back surface field region on the short-circuit current density is also presented. It has been found that the width and the surface recombination velocity of the undiffused gap on the rear side of the solar cell have a strong impact on the charge collection probability in the base. Thus, the surface recombination velocity of the undiffused gap has to be minimized or the undiffused gap has to be reduced or omitted completely in order to increase the short-circuit current density significantly. Furthermore, it has been found that low base doping concentrations are essential for minimizing the effective rear surface recombination velocity of the back surface field. It has also been shown that in the case of low base doping concentrations, the short-circuit current density reaches its maximum value and that in this case it is nearly independent of the back surface field doping concentration.
Leukemia and lymphoma immunophenotyping in cell smears with immunogold-silver staining. : (1990)

The potential of the immunogold-silver staining (IGSS) technique for immunophenotyping leukemia and lymphoma cells in cell smears was examined. Peripheral blood, bone marrow aspirates, lymph node biopsy specimens, fine-needle aspirates, and biologic fluids of 83 patients with acute or chronic leukemias, non-Hodgkin's lymphomas, or Hodgkin's disease were labeled. Cell smears, cytocentrifuge preparations, or imprints were fixed, incubated with the reagents, and counterstained with May-Grünwald-Giemsa. Stable immunostaining and good morphologic characteristics allowed accurate cell identification and rapid enumeration of the positive cells. The immunophenotypes obtained with the use of 35 monoclonal antibodies with different specificities were similar to those determined by flow cytometry or immunohistochemical studies on the same samples. This IGSS method was especially useful for the examination of poor samples or complex cell suspensions with rare malignant cells. It could be an alternative to the immunoenzyme methods that generally are used for this purpose.
Floating-Body Effects in AlGaN/GaN Power HFETs (2002)

AlGaN/GaN power HFETs grown on a 200nm thick AlN sub-buffer layer are investigated. The presence of a steady kink in the static and dynamic drain-to-source current characteristics is attributed to floating-body (FB) effects that result from the AlN sub-buffer layer. A method to extract the off-state body-to-source voltage (VBS) is applied and the coherence of the results confirms that FB effects are present in this type of structures. To our knowledge, this is the first time that floating-body effects are reported and modeled in AlGaN/GaN HFETs.
The Regulatory Domain of Human Heat Shock Factor 1 Is Sufficient To Sense Heat Stress (1996)

Heat shock factor (HSF) activates transcription in response to cellular stress. Human HSF1 has a central regulatory domain which can repress the activity of its activation domains at the control temperature and render them heat shock inducible. To determine whether the regulatory domain works in tandem with specific features of the HSF1 transcriptional activation domains, we first used deletion and point mutagenesis to define these activation domains. One of the activation domains can be reduced to just 20 amino acids. A GAL4 fusion protein containing the HSF 1 regulatory domain and this 20-amino-acid activation domain is repressed at the control temperature but potently activates transcription in response to heat shock. No specific amino acids in this activation domain are required for response to the regulatory domain; in particular, none of the potentially phosphorylated serine and threonine residues are required for heat induction, implying that heat-induced phosphorylation of the transcriptional activation domains is not required for induction. The regulatory domain is able to confer heat responsiveness to an otherwise completely heterologous chimeric activator that contains a portion of the VP16 activation domain, suggesting that the regulatory domain can sense heat in the absence of other portions of HSF1.
Insulin-dependent Diabetes Mellitus Appearing as Bilateral Mature Diabetic Cataracts in a Child (1997)

It is unusual for bilateral mature cataracts of rapid onset to be the initial manifestation of insulindependent diabetes mellitus. We describe who we believe to be 1 of the youngest children who appeared well but whose rapid cataract progression led to the diagnosis of diabetes mellitus. Report of a Case. A 9-year-old girl had progressive loss of vision in the left eye during a period of 11 days and in the right eye during a period of 6 days. Ocular history revealed that she had been examined by an ophthalmologist since age 2 years, and no lens abnormalities were ever noted. There was no family history of cataracts, diabetes, or other metabolic diseases. The patient was alert and healthy except for bilateral lenticular opacities. Visual acuity was hand motion OU. The pupils reacted normally to light. Findings from biomicroscopic examination revealed swollen lenses with bilateral diffuse dense opacities. Water clefts,
Combined Analyses of Data From Quantitative Trait Loci Mapping Studies: Chromosome 4 Effects on Porcine Growth and Fatness (2000)

For many species several similar QTL mapping populations have been produced and analyzed independently. Joint analysis of such data could be used to increase power to detect QTL and evaluate population differences. In this study, data were collated on almost 3000 pigs from seven different F(2) crosses between Western commercial breeds and either the European wild boar or the Chinese Meishan breed. Genotypes were available for 31 markers on chromosome 4 (on average 8.3 markers per population). Data from three traits common to all populations (birth weight, mean backfat depth at slaughter or end of test, and growth rate from birth to slaughter or end of test) were analyzed for individual populations and jointly. A QTL influencing birth weight was detected in one individual population and in the combined data, with no significant interaction of the QTL effect with population. A QTL affecting backfat that had a significantly greater effect in wild boar than in Meishan crosses was detected. Some evidence for a QTL affecting growth rate was detected in all populations, with no significant differences between populations. This study is the largest F(2) QTL analysis achieved in a livestock species and demonstrates the potential of joint analysis.
Ticlopidine‐induced neutropenia mimicking sepsis early after intracoronary stent placement (1998)

We report a case of ticlopidine-induced profound neutropenia early in the course of therapy, which was manifest as a febrile systemic illness mimicking sepsis. This clinical presentation was potentially indicative of a contaminated intracoronary stent. The patient's signs and symptoms of illness promptly resolved with removal of ticlopidine, and no infection was documented. Review of indications for ticlopidine use, potential adverse effects, and monitoring recommendations are discussed.
