A non-destructive technique for the determination of spatial charge and polarization distributions in insulating polymers (1990)

Recently, a laser intensity modulation method (LIMM) has been developed to determine spatial distributions of both polarization and space charge in the bulk of polymeric insulators. Polarization arising from field-induced orientation of dipoles and trapped space charges provides pyroelectric current when a metal-polymer-metal sandwich is heated with a laser beam that is intensity modulated in an appropriate range of frequencies. Present work provides an improved analytical technique to transform the pyroelectric current-frequency data into a spatial distribution of polarization and space charges. Some experimental results with a polar polymer and the associated spatial distribution of polarization are presented in support of the mathematical model.
Parallel computation of multiple biological sequence comparisons (1990)

A parallel implementation of an efficient method for comparison of multiple DNA sequences is presented. The method is described in terms of a conceptual tree data structure for the sequences to be compared. The parallel algorithm shows efficient utilization of processors on an Encore Multimax computer in a sample comparison of 11 sequences totaling over 4000 bases. Timing data show the strong influence of computer system details on this parallel program. Also presented is a graphics program for displaying multiple sequence comparison output data. The display is capable of representing large volumes of multiple sequence comparison data in a single plot. The program has several additional features that allow closer examination of subsets of sequences. A display of matches from the sample comparison reflects the known structure of these sequences.
Freeform illumination design: a nonlinear boundary problem for the elliptic Monge–Ampére equation (2013)

We propose an approach to deal with the problem of freeform surface illumination design without assuming any symmetry based on the concept that this problem is similar to the problem of optimal mass transport. With this approach, the freeform design is converted into a nonlinear boundary problem for the elliptic Monge–Ampére equation. The theory and numerical method are given for solving this boundary problem. Experimental results show the feasibility of this approach in tackling this freeform design problem.
Field Trapping and Observations of Male Velvetbean Caterpillar Moths and Trapping ofMocisspp. (Lepidoptera: Noctuidae: Catacolinae) with Calibrated Formulations of Sex Pheromone (1989)

Responses of male velvetbean caterpillar moths, Anticarsia gemmatalis Hübner, were examined in field tests of cone-type traps baited with the female sex pheromone compounds, (Z,Z,Z)-3,6,9-eicosatriene (C20) and (Z,Z,Z)-3,6,9, heneicosatriene (C21). Various blends, formulated on rubber septa, were quantified in the laboratory for release rate and release ratio of the C20 and C21 components; the optimum release ratio (C20:C21) and rate for the capture of males were 78:22 and 10 ng/h, respectively. This specificity was not apparent unless both parameters of release rate and ratio were tested. The number of males observed flying in a viewing area in the field was increased significantly by the presence of C20:C21 blends; however, the close approach of males and sustained hovering at baits were more blend sensitive than other behaviors. Three species of the genus Mocis also responded to the velvetbean caterpillar pheromone components: disseverans (Walker), latipes (Guénée), and marcida (Guénée). M. disseverans was captured in large numbers and responded preferentially to baits that released about 50% or more C21. The most M. disseverans were captured at traps containing only C21.

GUDMAP (2008)

In late 2004, an International Consortium of research groups were charged with the task of producing a high-quality molecular anatomy of the developing mammalian urogenital tract (UGT). Given the importance of these organ systems for human health and reproduction, the need for a systematic molecular and cellular description of their developmental programs was deemed a high priority. The information obtained through this initiative is anticipated to enable the highest level of basic and clinical research grounded on a 21st-century view of the developing anatomy. There are three components to the Genitourinary Developmental Molecular Anatomy Project GUDMAP; all of these are intended to provide resources that support research on the kidney and UGT. The first provides ontology of the cell types during UGT development and the molecular hallmarks of those cells as discerned by a variety of procedures, including in situ hybridization, transcriptional profiling, and immunostaining. The second generates novel mouse strains. In these strains, cell types of particular interest within an organ are labeled through the introduction of a specific marker into the context of a gene that exhibits appropriate cell type or structure-specific expression. In addition, the targeting construct enables genetic manipulation within the cell of interest in many of the strains. Finally, the information is annotated, collated, and promptly released at regular intervals, before publication, through a database that is accessed through a Web portal. Presented here is a brief overview of the Genitourinary Developmental Molecular Anatomy Project effort.
Polyphosphazenes: Synthesis—properties—applications (1975)

Abstract Various aspects of polyphosphazene chemistry are reviewed. Stable poly (organophosphazenes) can be prepared from an inorganic precursor, poly(dichlorophosphazene), by careful control of polymerization and substitution reaction conditions. The bulk structure and properties of polyphosphazenes are discussed, and attention is given to those polymers which have promise as useful engineering materials. The successful preparation of stable poly(organophosphazenes) appears to have resulted in a new class of polymers for both specialty and large scale commercial development.
Stabilized ^3He–^20Ne transverse Zeeman laser (1980)

Tuning characteristics of power, intramode beat frequency, and polarization of 633-nm internal mirror lasers filled with natural Ne or (20)Ne are studied. It is found that the tuning curve of a polarization signal is S-shaped for the natural Ne laser, whereas that of the intramode beat frequency is S-shaped for the (20)Ne laser. The characteristic parameters of the tuning curve of the intramode beat frequency are determined. The axial modes of a (3)He-(20)Ne laser are collapsed into one by a transverse magnetic field and frequency stabilized by cooling the laser tube with a fan to keep the intramode beat constant. Frequency fluctuation of 3 x 10(-10) is obtained by the Allan variance analysis for the integration period range of 0.1-100 sec. Absolute accuracy and interinstrumental reproducibility of stabilized wavelengths can be expected for a (3) He-(20)Ne transverse Zeeman laser stabilized at the central frequency of the intramode beat.
Trademark matching and retrieval in sports video databases (2007)

In this paper we describe a system for detection and retrieval of trademarks appearing in sports videos. We propose a compact representation of trademarks and video frame content based on SIFT feature points. This representation can be used to robustly detect, localize, and retrieve trademarks as they appear in a variety of different sports video types. Classification of trademarks is performed by matching a set of SIFT feature descriptors for each trademark instance against the set of SIFT features detected in each frame of the video. Localization is performed through robust clustering of matched feature points in the video frame. Experimental results are provided, along with an analysis of the precision and recall. Results show that the our proposed technique is efficient and effectively detects and classifies trademarks.
Shape-Aware Human Pose and Shape Reconstruction Using Multi-View Images (2019)

We propose a scalable neural network framework to reconstruct the 3D mesh of a human body from multi-view images, in the subspace of the SMPL model. Use of multi-view images can significantly reduce the projection ambiguity of the problem, increasing the reconstruction accuracy of the 3D human body under clothing. Our experiments show that this method benefits from the synthetic dataset generated from our pipeline since it has good flexibility of variable control and can provide ground-truth for validation. Our method outperforms existing methods on real-world images, especially on shape estimations.
An Examination by Site-Directed Mutagenesis of Putative Key Residues in the Determination of Coenzyme Specificity in Clostridial<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msup><mml:mrow><mml:mtext>NAD</mml:mtext></mml:mrow><mml:mo mathvariant="bold">+</mml:mo></mml:msup></mml:mrow></mml:math>-Dependent Glutamate Dehydrogenase (2011)

Sequence and structure comparisons of various glutamate dehydrogenases (GDH) and other nicotinamide nucleotide-dependent dehydrogenases have potentially implicated certain residues in coenzyme binding and discrimination. We have mutated key residues in Clostridium symbiosum NAD(+)-specific GDH to investigate their contribution to specificity and to enhance acceptance of NADPH. Comparisons with E. coli NADPH-dependent GDH prompted design of mutants F238S, P262S, and F238S/P262S, which were purified and assessed at pH 6.0, 7.0, and 8.0. They showed markedly increased catalytic efficiency with NADPH, especially at pH 8.0 (∼170-fold for P262S and F238S/P262S with relatively small changes for NADH). A positive charge introduced through the D263K mutation also greatly increased catalytic efficiency with NADPH (over 100-fold at pH 8) and slightly decreased activity with NADH. At position 242, "P6" of the "core fingerprint," where NAD(+)- and NADP(+)-dependent enzymes normally have Gly or Ala, respectively, clostridial GDH already has Ala. Replacement with Gly produced negligible shift in coenzyme specificity.
Bioavailability of Tetracycline and Doxycycline in Fasted and Nonfasted Subjects (1977)

The influence of various test meals and fluid volumes on the relative bioavailability of commercial formulations of doxycycline hyclate and tetracycline hydrochloride was studied in healthy human volunteers. Serum levels of tetracycline were uniformly reduced by approximately 50% by all test meals, whereas serum levels of doxycycline were reduced by 20%. The reduction of tetracycline serum levels will likely be of clinical significance. The bioavailability of each drug was almost identical from an oral solution and from capsules in fasted subjects. The rate of doxycycline absorption was reduced when capsules were administered with a small volume of water, but the overall efficiency of absorption of both drugs was essentially independent of co-administered fluid volume. The use of 8-h serum data provides a reliable estimate of drug bioavailability for tetracycline and, to a lesser extent, for doxycycline.
Evidence for Scgb1a1+ Cells in the Generation of p63+ Cells in the Damaged Lung Parenchyma (2013)

Transformation-related protein 63-expressing (p63(+)) basal cells are confined to the trachea in the mouse lung. However, after influenza virus infection or bleomycin treatment, patches of p63(+) cells were observed in the damaged lung parenchyma. To address whether the newly induced p63(+) cells are derived from the p63(+) basal cells, we performed lineage tracing. In a keratin 5 promoter-driven CreER system, although preexisting p63(+) basal cells were labeled by enhanced green fluorescent protein (EGFP) after tamoxifen treatment, none or only a small fraction (∼ 15%) of the p63(+) patches was labeled by EGFP after bleomycin treatment or influenza virus infection, respectively. In contrast, > 60% of p63(+) patches contained EGFP(+) cells in Scgb1a1-CreER transgenic system where club cells are labeled. Many p63(+) cells were found in bronchiole-like lumen structures with columnar cells at the lumen side. The columnar cells were positive for club cell marker Cyp2f2 and could be traced to the newly induced p63(+) cells. These results suggest that most of the newly induced p63(+) cells in the damaged parenchyma are likely derived from club cells rather than from p63(+) basal cells and that newly induced p63(+) cells may be involved in the regeneration of bronchioles.
Rosacea: A Clinicopathological Approach (2004)

Rosacea seems to be a reaction pattern to which a variety of pathogenetic routes may lead.
SPARC (1998)

In an attempt to identify genetic alterations occurring early in astrocytoma progression, we performed subtractive hybridization between astrocytoma and glioblastoma cDNA libraries. We identified secreted protein acidic and rich in cysteine (SPARC), a protein implicated in cell-matrix interactions, as a gene overexpressed early in progression. Northern blot and immunohistochemical analyses indicated that transcript and protein were both elevated in all tumor specimens (grades II-IV) examined when compared with levels in normal brain. The level of SPARC expression was found to be tumor-dependent rather than grade-related. Immunohistochemically, SPARC protein was found to be overexpressed in 1) cells in the less cellularly dense regions within the tumor mass, 2) histomorphologically neoplastic-looking cells in adjacent normal brain at the tumor/brain interface, 3) neovessel endothelial cells in both the tumor and adjacent normal brain, and 4) reactive astrocytes in normal brain adjacent to tumor. Using a combination of DNA in situ hybridization and protein immunohistochemical analyses of the human/rat xenograft, SPARC expression was observed in the human glioma cells within the tumor mass, and in cells that invaded along vascular basement membranes and individually into the rat brain parenchyma, suggesting it may be an invasion-related gene. While it remains to be determined whether SPARC functionally contributes to tumor cell invasion, these data suggest that the early onset of increased SPARC expression, though complex, may serve as a signal indicative of neoplastic astrocytic transformation and reactive response to tumor-induced stress.
Thermal Considerations for the Design of an Implanted Cortical Brain–Machine Interface (BMI) (2007)

Devices for the brain–machine interface (BMI) are no longer science fiction but are being tested in patients with severe paralysis and advanced neuromuscular diseases. While the feasibility of controlling a device using brain-derived neural signals has been demonstrated, the first practical system for acquiring and processing these signals has yet to appear. This is in part because the implanted device technology needed to make a clinical BMI is substantially different in many ways from existing implanted devices. As described below, the BMI will use significantly more power than other implants. More power leads to the necessity of dissipating more heat inside the body.This chapter discusses tissue heating by the BMI components, one of the engineering challenges that need to be solved in order to create a functional BMI. A functional overview of a cortical BMI is given, with particular attention paid to the sources of heat, followed by a section reviewing quantitative methods to examine these sources of heat. A review of the literature characterizing tissue response to heating follows, and finally recommendations are made regarding BMI system design based on considerations of heat dissipation.
Direct Reading Ratio-Error Sets for the Calibration of Current Transformers (1970)

Four different direct reading ratio-error sets, capable of generating measured complex fractions of an input reference current to a nominal accuracy of 1 percent of reading for such applications as current-transformer calibration, are described and analyzed. Construction and performance details for actual sets with 3 or more digit resolution in both direct and quadrature components from 0.1 parts per million to 10 percent of input currents up to 10 amperes at 50, 60, and 400 Hz, are given.
Towards in vivo laser coagulation and concurrent optical coherence tomography through double-clad fiber devices (2016)

There is a strong clinical need for an optical coherence tomography (OCT) system capable of delivering concurrent coagulation light enabling image-guided dynamic laser marking for targeted collection of biopsies, as opposed to a random sampling, to reduce false-negative findings. Here, we present a system based on double-clad fiber (DCF) capable of delivering pulsed laser light through the inner cladding while performing OCT through the core. A previously clinically validated commercial OCT system (NVisionVLE, Ninepoint Medical) was adapted to enable in vivo esophageal image-guided dynamic laser marking. An optimized DCF coupler was implemented into the system to couple both modalities into the DCF. A DCF-based rotary joint was used to couple light to the spinning DCF-based catheter for helical scanning. DCF-based OCT catheters, providing a beam waist diameter of 62μm at a working distance of 9.3mm, for use with a 17-mm diameter balloon sheath, were used for ex vivo imaging of a swine esophagus. Imaging results using the DCF-based clinical system show an image quality comparable with a conventional system with minimal crosstalk-induced artifacts. To further optimize DCF catheter optical design in order to achieve single-pulse marking, a Zemax model of the DCF output and its validation are presented.
The c-Abl Tyrosine Kinase Is Regulated Downstream of the B Cell Antigen Receptor and Interacts with CD19 (2000)

c-Abl is a nonreceptor tyrosine kinase that we have recently linked to growth factor receptor signaling. The c-Abl kinase is ubiquitously expressed and localizes to the cytoplasm, plasma membrane, cytoskeleton, and nucleus. Thus, c-Abl may regulate signaling processes in multiple subcellular compartments. Targeted deletion or mutation of c-Abl in mice results in a variety of phenotypes, including splenic and thymic atrophy and lymphopenia. Additionally, lymphocytes isolated from specific compartments of c-Abl mutant mice have reduced responses to a variety of stimuli and an increased susceptibility to apoptosis following growth factor deprivation. Despite these observations, little is known regarding the signaling mechanisms responsible for these phenotypes. We report here that splenic B cells from c-Abl-deficient mice are hyporesponsive to the proliferative effects of B cell Ag receptor (BCR) stimulation. The c-Abl kinase activity and protein levels are elevated in the cytosol following activation of the BCR in B cell lines. We show that c-Abl associates with and phosphorylates the BCR coreceptor CD19, and that c-Abl and CD19 colocalize in lipid membrane rafts. These data suggest a role for c-Abl in the regulation of B cell proliferation downstream of the BCR, possibly through interactions with CD19.
CO2 utilization: Developments in conversion processes (2016)

Carbon dioxide capture, utilization and storage (CCUS) –including conversion to valuable chemicals-is a challenging contemporary issue having multi-facets. The prospect to utilize carbon dioxide (CO2) as a feedstock for synthetic applications in chemical and fuel industries -through carboxylation and reduction reactions-is the subject of this review. Current statute of the heterogeneously catalyzed hydrogenation, as well as the photocatalytic and electrocatalytic activations of conversion of CO2 to value-added chemicals is overviewed. Envisaging CO2 as a viable alternative to natural gas and oil as carbon resource for the chemical supply chain, three stages of development; namely, (i) existing mature technologies (such as urea production), (ii) emerging technologies (such as formic acid or other single carbon (C1) chemicals manufacture) and (iii) innovative explorations (such as electrocatalytic ethylene production) have been identified and highlighted. A unique aspect of this review is the exploitations of reactions of CO2 –which stems from existing petrochemical plants-with the commodity petrochemicals (such as, methanol, ethylene and ethylene oxide) produced at the same or nearby complex in order to obtain value-added products while contributing also to CO2 fixation simultaneously. Exemplifying worldwide ethylene oxide facilities, it is recognized that they produce about 3 million tons of CO2 annually. Such a CO2 resource, which is already separated in pure form as a requirement of the process, should best be converted to a value-added chemical there avoiding current practice of discharging to the atmosphere. The potential utilization of CO2, captured at power plants, should also been taken into consideration for sustainability. This CO2 source, which is potentially a raw material for the chemical industry, will be available at sufficient quality and at gigantic quantity upon realization of on-going tangible capture projects. Products resulting from carboxylation reactions are obvious conversions. In addition, provided that enough supply of energy from non-fossil resources, such as solar [1], is ensured, CO2 reduction reactions can produce several valuable commodity chemicals including multi-carbon compounds, such as ethylene and acrylic acid, in addition to C1 chemicals and polymers. Presently, there are only few developing technologies which can find industrial applications. Therefore, there is a need for concerted research in order to assess the viability of these promising exploratory technologies rationally.
EFFET OPTOGALVANIQUE DANS UNE DÉCHARGE À CATHODE CREUSE : MÉCANISME ET DOSAGE ISOTOPIQUE DE L'URANIUM (1983)

Nous présentons les résultats des travaux qui ont permis de démontrer que le mécanisme responsable de l'effet optogalvanique dans les lampes a cathode creuse, lors du pompage optique sur une transition de l'espèce pulvérisée, est le chauffage global du plasma. Ce chauffage est dû à la redistribution par collision électronique de l'énergie laser absorbée. Par la suite, la production d'ions, associée au pompage optique, est non sélective. Comme application de cet effet nous démontrons que la spectroscopie optogalvanique est une méthode prometteuse pour le dosage isotopique de l'uranium. Les valeurs obtenues de l'abondance de l'isotope 235 dans l'uranium naturel sont en bon accord avec les déterminations effectuées par spectrométrie de masse. Cette méthode est beaucoup plus sensible que les méthodes conventionnelles de spectroscopie d'absorption et d'émission. Pour nos conditions expérimentales la limite de détection calculée d'un isotope pair d'uranium est d'environ 106 atomes/cm3, ce qui correspond à une abondance isotopique de 0.00015%.
Processing Top N and Bottom N Queries. (1997)

this paper addresses the question of how top N and bottom N queries can be processed efficiently; moreover, we address the question of how such support can be provided as a natural extension of existing relational query processing architectures. In a nutshell, our goal is to evaluate such queries with as little wasted work
