Reflexive and voluntary orienting of visual attention: Time course of activation and resistance to interruption. (1989)

To study the mechanisms underlying covert orienting of attention in visual space, subjects were given advance cues indicating the probable locations of targets that they had to discriminate and localize. Direct peripheral cues (brightening of one of four boxes in peripheral vision) and symbolic central cues (an arrow at the fixation point indicating a probable peripheral box) were compared. Peripheral and central cues are believed to activate different reflexive and voluntary modes of orienting (Jonides, 1981; Posner, 1980). Experiment 1 showed that the time courses of facilitation and inhibition from peripheral and central cues were characteristic and different. Experiment 2 showed that voluntary orienting in response to symbolic central cues is interrupted by reflexive orienting to random peripheral flashes. Experiment 3 showed that irrelevant peripheral flashes also compete with relevant peripheral cues. The amount of interference varied systematically with the interval between the onset of the relevant cue and of the distracting flash (cue-flash onset asynchrony) and with the cuing condition. Taken together, these effects support a model for spatial attention with distinct but interacting reflexive and voluntary orienting mechanisms.
Further dihydrochalcones from Crotolaria ramosissima (1999)

Two new dihydrochalcones, crotaramin (2) and crotin (3), have been isolated from the Indian plant Crotolaria ramosissima. Their structures have been elucidated by extensive one- and two-dimensional NMR spectroscopy including HMBC and NOESY.
Solid-Phase Synthesis of a Fragment of the Capsular Polysaccharide of<i>Haemophilus Influenzae</i>Type B Using<i>H</i>-Phosphonate Intermediates (1992)

Abstract A pentameric fragment of the capsular polysaccharide of Haemophilus influenzae type b, containing a linker group, was synthesized by a simple solid-phase procedure. Cross-linked polystyrene was used as a solid phase, and a benzyl-protected ribosylribitol H-phosphonate was used as monomer. A non-promoted glycosidation reaction was used for preparation of the ribosylribitol monomer.
An enhanced handover oscillation control algorithm in LTE Self-Optimizing networks (2011)

In this paper we propose a new horizontal handover oscillation control algorithm for Long Term Evolution (LTE) Self-Optimizing based Networks (SON). Based on a pre-established policy, this algorithm automatically adjusts the Hysteresis and Time-To-Trigger (TTT) based on Ping-Pong Handover Performance Indicator (HPI). Additionally, the User Equipment (UE) type of traffic and speed is taken into account for a more accurate handover decision. Results show clear improvements when compared with other proposals, namely the fixed parameter scenario.
On the invertibility of invisible watermarking techniques (2002)

We shall show that non-invertibility is a necessary but not sufficient condition in resolving ownership disputes. We then define quasi-invertible watermarking schemes, and, present analysis that links invertibility and quasi-invertibility to some classes of watermarking techniques with different properties (which may or may not require original versions in watermark decoding), as well as to the different classes of attacks we have developed.
Theoretical and experimental studies of the atomic structure of oxygen-rich amorphous silicon oxynitride films (2003)

In this work we used an empirical potential model in order to describe the bulk structure of the oxygen-rich Si-O-N amorphous system. From the atomic configuration obtained by Monte Carlo simulations, the local order structure and the pair correlation function are determined. The results show that the basic structure of the amorphous is well described by a random distribution of tetrahedra with a central Si atom bonded to nitrogen and oxygen atoms. The Fourier transform of the extended x-ray-absorption fine structure (EXAFS) signal obtained by ab initio multiple-scattering calculations, using the theoretical atomic structure as input, shows good agreement with the experimental EXAFS analysis performed at the silicon K edge.
Greening the Blacktop: Using Asphalt's Environmental Qualities to Compete (2008)

This article explains the concept of LEED (Leadership in Energy and Environmental Design), a green building rating system, and how asphalt pavements can meet LEED standards. As more municipalities and federal facilities require that certain projects meet green building requirements, asphalt’s role is an important one, especially in the overall LEED rating of a development. Its greatest contribution is stormwater management through the use of porous asphalt. In addition, several techniques for mitigating urban heat island effect can be affected by asphalt usage. The author describes how porous pavements can generate LEED credits, as well as how the urban heat island can be mitigated by providing lighter-colored asphalt surfaces. A number of ways to make asphalt surfaces lighter are suggested. The ability to recycle hot mix asphalt also provides LEED credits. The author concludes that asphalt pavements can potentially provide more LEED credits than other types of pavement.
Molecular Factors Affecting the Accumulation of Recombinant Proteins in the Chlamydomonas reinhardtii Chloroplast (2010)

In an effort to develop microalgae as a robust system for the production of valuable proteins, we analyzed some of the factors affecting recombinant protein expression in the chloroplast of the green alga Chlamydomonas reinhardtii. We monitored mRNA accumulation, protein synthesis, and protein turnover for three codon-optimized transgenes including GFP, bacterial luciferase, and a large single chain antibody. GFP and luciferase proteins were quite stable, while the antibody was less so. Measurements of protein synthesis, in contrast, clearly showed that translation of the three chimeric mRNAs was greatly reduced when compared to endogenous mRNAs under control of the same atpA promoter/UTR. Only in a few conditions this could be explained by limited mRNA availability since, in most cases, recombinant mRNAs accumulated quite well when compared to the atpA mRNA. In vitro toeprint and in vivo polysome analyses suggest that reduced ribosome association might contribute to limited translational efficiency. However, when recombinant polysome levels and protein synthesis are analyzed as a whole, it becomes clear that other steps, such as inefficient protein elongation, are likely to have a considerable impact. Taken together, our results point to translation as the main step limiting the expression of heterologous proteins in the C. reinhardtii chloroplast.
An Integrated GPS/GLONASS Receiver (1993)

Utilization of a safe and economical
satellite navigation system for civil
aviation becomes more important, as a
current experimental stage will be
transferred to a fully operational stage
soon. The ICAO’s special committee of
Future Air Navigation systems (FANS) had
many technical investigations and examined
technical issues on GNSS(Globa1 Navigation
Satellite Systems). The committee reached
the conclusion that one of the most useful
solutions of the issues is an integrated
use of USA’s GPS and Russian GLONASS for
civil aviation navigation to meet the
integrity requirement. In Japan also,
examinations of the integrated use of GPS
and GLONASS have been started since 1991
mainly by Japan Civil Aviation
Bureau( JCAB). Japan Civil Aviation
Promotion Foundation(JCAPF) entrusted Japan
Radio Co., Ltd. (JR0 with a trial
manufacture of an experimental receiver in
1992. Several flight tests for purposes of
evaluation are scheduled this year jointly
by JRC and Electronic Navigation Research
Institute(ENR1).
This paper describes an outline of
architecture, composition and technical
problems with evaluation results of the
GPS/GLONASS integrated receiver we made.
The receiver is able to receive up to 16
satellite signals with 8 GPS channels and 8
GLONASS channels respectively. Position fix
is done in all-in-view mode. Time offsets
between user clock and the two systems
clocks as well as user position are solved
from more than 5 navigation equations when
two kinds of satellites are received. The
receiver has an online calibration function
of separated analog I. F. channels to
compensate differences among channel group
delays and improve accuracy of position
fixes. The RAIM functions specified in
MOPS[ll are satisfied. The receiver is
still in an experimental stage, but is
conformed to ARINC project paper 743.121
Enantioselective organocatalytic Michael additions of N,N′-dialkylbarbituric acids to enones (2017)

N,N'-Dialkylbarbituric acids as cyclic malonamide donors were successfully used in the enantioselective Michael addition reaction of enones. Using cinchona alkaloid-based bifunctional squaramide as an organocatalyst, this Michael reaction of N,N'-di-tert-butylbarbituric acid with various enones features a highly enantioselective (91-99% ee) production of the corresponding optically active 5-substituted barbituric acid derivatives. The transformations of the Michael product for the barbituric acid structural unit were realized in two ways, deprotection to remove the N-tert-butyl group and alkylation to produce 5,5-disubstituted barbituric acid derivatives.

Diagnosis of meningioma by time-resolved fluorescence spectroscopy (2005)

We investigate the use of time-resolved laser-induced fluorescence spectroscopy (TR-LIFS) as an adjunctive tool for the intraoperative rapid evaluation of tumor specimens and delineation of tumor from surrounding normal tissue. Tissue autofluorescence is induced with a pulsed nitrogen laser (337 nm, 1.2 ns) and the intensity decay profiles are recorded in the 370 to 500 nm spectral range with a fast digitizer (0.2 ns resolution). Experiments are conducted on excised specimens (meningioma, dura mater, cerebral cortex) from 26 patients (97 sites). Spectral intensities and time-dependent parameters derived from the time-resolved spectra of each site are used for tissue characterization. A linear discriminant analysis algorithm is used for tissue classification. Our results reveal that meningioma is characterized by unique fluorescence characteristics that enable discrimination of tumor from normal tissue with high sensitivity (>89%) and specificity (100%). The accuracy of classification is found to increase (92.8% cases in the training set and 91.8% in the cross-validated set correctly classified) when parameters from both the spectral and the time domain are used for discrimination. Our findings establish the feasibility of using TR-LIFS as a tool for the identification of meningiomas and enables further development of real-time diagnostic tools for analyzing surgical tissue specimens of meningioma or other brain tumors.
Etching of aluminum alloys in the transformer-coupled plasma etcher (1994)

Transformer-coupled plasma (TCP) technology has been applied to the etching of aluminum alloys. High density plasmas can be obtained at low pressures (∼10 mTorr) by inductive coupling of externally applied radio frequency (rf) power at the frequency of 13.56 MHz. The energy of the ions incident to the substrate is controlled by a separate capacitively coupled rf power supply. Cl2 and BCl3 gas chemistries were used for the etching. The characteristics of the plasma have been studied with a Langmuir probe and the ‘‘complex conjugate method.’’ The ion current density is mainly dependent on the rf power to the coil and gas pressure. The energy of ions bombarding the substrate surface can be controlled by changing the rf power to the bottom electrode and the coil. A statistical experimental method and optical emission spectroscopy were used to study the etching of the aluminum alloys with a TCP source. The results indicate that etching of aluminum alloys is dominated by chemical interaction with Cl2 gas whereas photoresist is etched by the bombardment of energetic ions.
Mechanisms of IgE tolerance: Dual regulatory T cell lesions in perinatal IgE tolerance (1991)

The mechanisms of genetic control of IgE responses are exercised at different immuno-physiological levels. This study centered upon the development of IgE lineage-specific regulatory T cells. Herein, we demonstrate the following points: (a) perinatal administration of soluble self IgE molecule or self IgE complexed with foreign antigen induces IgE tolerance as manifested by antigen-specific IgE unresponsiveness and a generalized IgE immunodeficiency, and the induction of IgE tolerance does not affect antigen-specific IgG1, IgG, and IgA responses; (b) inducibility of perinatal IgE tolerance is correlated with complete absence of endogenously secreted IgE in the neonates; and the state of persistent IgE tolerance also does not correlate with the presence of high levels of circulating anti-IgE autoantibodies; (c) The lesions induced during the ontogeny of IgE antibody system do not appear to result from an imbalance of production of interleukin 4 and interferon-gamma by T helper Th2 and Th1 cells in antigen-stimulated cultures; the dual immunoregulatory lesions in T cell subsets are demonstrated: clonal anergy/deletion of CD4+ IgE Th cells and the presence of CD8+ IgE suppressor cells induced by perinatal IgE treatment. We propose that antigen/interleukin 4 activated B cells are controlled by IgE lineage-specific regulatory T cells which recognize self IgE determinant(s) on IgE committed B cells. Life-long IgE tolerance ensues as a result of a new steady state of IgE lineage-specific CD4+ and CD8+ T cell subsets.
[Changes in thyroid function in systemic lupus erythematosus, progressive systemic sclerosis and rheumatoid arthritis]. (1994)

According to frequent thyroid function disorders in systemic connective tissue diseases a group of 380 patients were analysed - 70 with systemic erythematous lupus (SLE), 31 with progressive systemic scleris (PSS) and 270 with rheumatoid arthritis (RA). Thyroxine (T4) and triodothyronine (T3) were measured by radioimmunoassay technique and thyroid stimulating hormone (TSH) chronologically by monoclonal antibody technique and thereafter by fluoroimmunoassay. Thyreopahty was found at 15 patients with SLE (21.43%), 11 patients with PSS (35.48%) and 35 patients with RA (12.54%). Our results pointed out the significant frequency of thyroid function disorders in these diseases and imply the necessity of the routine thyroid function follow up, therefore to take adequate cure in due time.
Monoclonal antibodies to the myogenic regulatory protein MyoD1: epitope mapping and diagnostic utility. (1992)

Monoclonal antibodies (MoAbs) were developed against recombinant wild-type murine MyoD1 protein. Each of 4 MoAbs was immunologically reactive with recombinant MyoD1 protein by enzyme-linked immunosorbent assay, and each specifically stained the nuclei of myogenic cells. Epitopes were mapped using fusion protein constructs with specific deletions of defined regions of the MyoD1 molecule. MoAb 5.2F recognized an epitope in the amino terminal region between amino acid residues (AAR) 3 and 56, whereas epitopes for MoAbs 1.1A, 5.4G, and 5.8A were in the carboxyl terminus (AAR 167-318) of the MyoD1 protein. The epitope for MoAb 5.8A was further delineated to AAR 170-209 by Western analysis and immunoprecipitation of in vivo transcribed and translated MyoD1 protein having specific deletions in the carboxyl terminus. The 5.8A epitope was ultimately localized to the region between AAR 180 and 189 of the protein by enzyme-linked immunosorbent assay using 10-amino acid residue synthetic peptides. This sequence is apparently unique to MyoD1 and has little homology to other myogenic regulatory proteins (myogenin, Myf5, Myf6, and MRF4). Transfection of cDNA for murine MyoD1 into a nonmuscle cell line conferred 5.8A reactivity, confirming the specificity of this reagent. MoAb 5.8A was then used to examine the expression of MyoD1 in normal and malignant human tissues. MyoD1 was not detected in any normal adult tissue but was detected in 25 of 25 histologically confirmed rhabdomyosarcomas. Staining was localized to the nucleus and showed marked heterogeneity between cells as well as differential staining within nuclei. Specific subcellular localization of 5.8A was further determined by immunoelectron microscopy, where antibody was found to localize to electron-dense areas, more frequently associated with the nuclear submembranous region. In addition to rhabdomyosarcomas, MoAb 5.8A stained 2 of 5 Wilms' tumors and one ectomesenchymoma, neoplasms known to contain myogenic elements. The 5.8A reagent was also of value in the accurate histopathological classification of 2 of 4 tumors previously diagnosed as extraosseous Ewing's sarcoma and 2 of 3 tumors diagnosed as undifferentiated sarcomas.
Surfactant and Varespladib Co-Administration in Stimulated Rat Alveolar Macrophages Culture (2013)

Acute lung injury is a life-threatening condition characterized by surfactant dysfunction and raised secretory phospholipase A2 (sPLA2) activity. Varespladib is a sPLA2 inhibitor shown to be effective in animal models of acute lung injury. We aimed at investigating the effect of co-administration of surfactant and varespladib on sPLA2 activity. Alveolar macrophages were cultured and stimulated with lipopolysaccharide and then treated with either varespladib, surfactant, varespladib followed by surfactant or nothing. sPLA2 activity, free fatty acids, tumour necrosis factor-α (TNF-α) and protein concentrations were measured in culture supernatants. Treatment with varespladib (p=0.019) and varespladib + surfactant (p=0.013), reduced the enzyme activity by approximately 15% from the basal level measured in the untreated cultures. Surfactant, varespladib and varespladib + surfactant, respectively decreased free fatty acids by -45% (p=0.045), - 62% (p=0.009) and -48% (p=0.015), from the baseline concentration of the untreated cultures. Varespladib and poractant- α co-administration reduces sPLA2 activity and free fatty acids release in cultured rat alveolar macrophages, although a clear drug synergy was not evident. Since co-administration may be useful to reduce inflammation and surfactant inactivation in acute lung injury, further in vivo studies are warranted to verify its clinical usefulness.
Broad area photonic crystal distributed feedback quantum cascade lasers emitting 34 W at λ∼4.36 μm (2010)

We demonstrate room temperature, high power, single mode, and diffraction limited operation of a two dimensional photonic crystal distributed feedback quantum cascade laser emitting at 4.36 μm. Total peak power up to 34 W is observed from a 3 mm long laser with 400 μm cavity width at room temperature. Far-field profiles have M2 figure of merit as low as 2.5. This device represents a significant step toward realization of spatially and spectrally pure broad area high power quantum cascade lasers.
An Empirical Investigation of Costs in Batching Decisions* (2000)

This paper examines the use of costs and cost functions to model lot‐sizing decisions in batch manufacturing. The cost functions used to model a wide variety of manufacturing systems are typically derived from average cost models of unconstrained inventory problems. The use of setups and average inventories as the basis for modeling the economics of a typical batch manufacturing cell is shown to be inadequate. An alternative physical model that focuses on lead times provides a model that more closely represents the underlying value of such a cell.
N‐Removal in a granular sludge sequencing batch airlift reactor (2001)

The removal of N-compounds in the sequencing batch airlift reactor (SBAR) containing granular sludge was studied under conditions of decreased dissolved oxygen (DO). A simulation model was developed to describe and evaluate the effects of several process conditions in the SBAR on N-removal performance. The model described the experimental data reasonable well. It has been shown that nitrification, denitrification, and removal of chemical oxygen demand (COD) can occur simultaneously in a granular sludge SBR. It has also been shown that the exact location of the autotrophic biomass influences the net N-removal. The distribution of the autotrophic biomass is influenced by the DO in the reactor. The optimal DO value is expected to be around 40% air saturation. It was shown that storage and subsequent degradation of poly-beta-hydroxybutyrate (PHB) benefit the denitrification. In particular, PHB is stored in bacteria situated in deeper layers of the granules below where the autotrophic activity occurs, serves as a C-source for denitrification.

Graphical Tests for Hardy-Weinberg Equilibrium Based on the Ternary Plot (2007)

The proposed graphs can be used as control charts for spotting problematic markers in large scale genotyping studies, and constitute an excellent tool for the graphical exploration of bi-allelic marker data.
