A 100-GHz-tunable photonic millimeter wave synthesizer for the Atacama Large Millimeter Array radiotelescope (2007)

We propose a broadband photonic millimeter wave synthesizer based on the optical phase locking of telecom-grade DFB semiconductor lasers. A mathematical model of the OPLL shows that the frequency noise profile of these lasers is such that millimeter wave beat notes with residual phase noise levels of 2 x 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-5</sup> rad <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> can be achieved with loop path lengths as long as 60 cm. Experiments on a simplified proof-of-concept unit validate this model. The synthesizer is tunable over more than 100 GHz by changing the laser junction temperature. The photonic millimeter wave synthesizer will be used to generate and distribute the LO reference signal of the Atacama Large Millimeter Array radiotelescope.
Blind randomised non-crossover long-term trial comparing topical timolol 0.25% with timolol 0.5% in the treatment of simple chronic glaucoma. (1983)

The results of a 12-month blind randomised trial comparing the intraocular pressure lowering effect of timolol 0.25% with timolol 0.5% are presented. 27% of patients (22% of eyes) required additional antiglaucoma medication after a minimum time interval of 6 months to maintain an intraocular pressure less than 23 mmHg. The mean reduction in intraocular pressure (from pretreatment values) at 12 months was 24% for eyes treated with timolol 0.25% and 19% for eyes treated with timolol 0.5%. When reductions in intraocular pressure at each follow-up interval were statistically significant (timolol 0.25% treated eyes compared with timolol 0.5% treated eyes), the significance always favoured timolol 0.25%.
Acremonium keratitis in a patient with herpetic neurotrophic corneal disease (2000)

Fungi belonging to the genus Acremonium Link ex Fries 1821 are ubiquitous environmental contaminants and soil saprophytes, but are infrequent pathogens in humans. These filamentous fungi (previously known as Cephalosporium) are an uncommon cause of mycotic keratitis. As in the case of other filamentous fungi, corneal trauma with contaminated matter is the most frequent risk factor for the infection. We report in this paper a case of keratomycosis caused by Acremoniumpotronii, in a patient with a history of herpetic keratitis. Medical treatment with amphotericin B was unsuccessful and the infection eventually resolved with penetrating keratoplasty.
The Fractionation of Copolymers by Chemical Composition (1968)

Abstract Phase diagrams for the system of methyl ethyl ketone, cyclo-hexane, and styrene-acrylonitrile copolymer were determined. The phase diagrams indicate that the copolymer may be fractionated by chemical composition in this system. Discussions of the thermodynamics are also presented, to show that copolymers can effectively be fractionated into fractions of different compositions if a system can be found in which the difference between the Flory interaction parameters (x parameters) of two constituents of the copolymer with solvent is sufficiently large. Theoretically, the fractionation of copolymer must always occur to a certain extent, depending both on chemical composition and molecular weight. The composition fractionation results of styrene-acrylonitrile copolymers are given to confirm the discussions.
Recent advances in waterglass sand technologies (2007)

This paper reports some new understandings and advances in waterglass sand technologies. The multiple chemical modification process can increase the binding strength of the waterglass sand by up to 50%-70%. Therefore, the additions of the modified waterglass can be decreased to 3.0%-4.0% for CO2 process and to 2.0%-2.5% for organic ester hardening process, and greatly improve the collapsibility and reclaimability of the sand. Based on the new understandings and experimental results reported in this paper, several original ideas, such as nano modification, have been proposed to promote advances of waterglass sand technologies.
Automatic landing method of a reclaimer on the stockpile (1999)

Large excavation reclaimers are used to dig ore and transfer it to the blast furnaces that refine the ore into pure metal form. The reclaiming job consists of two operations: (1) landing a reclaimer bucket on the surface of a pile and (2) slewing its boom with rotating buckets to scoop the ore. An automatic landing method for choosing where to dig in a pile of raw ore is proposed to achieve autonomous reclaiming. The method comprises detecting the shape of a pile, extracting contour lines of the pile, obtaining the joint angles of the reclaimer and determining an optimal landing point. A 3D range finder was developed with laser radar concepts to detect the shape and height of the ore pile. A series of image processing techniques for extracting the contour line from the 3D range data of a pile is suggested. A height map is obtained from the acquired range data for a pile and a contour map is obtained through image processing steps, including interpolation and edge following. The optimal landing point of the bucket on the contour line is determined so that an overload problem does not occur in the slewing operation and the reclaiming efficiency can be maximized. The algorithm for finding the landing point requires an inverse kinematics solution for the reclaimer. The forward kinematics of the reclaimer is first obtained. A constraint equation based on the geometrical relationship is suggested to solve the inverse kinematics of the reclaimer with redundancy. The proposed method was successfully applied to a working reclaimer. An autonomous reclaimer is now being operated in the yards of Kwangyang Steelworks in Korea.
Tumor-derived p53 mutant C174Y is a gain-of-function mutant which activates the fos promoter and enhances colony formation (2000)

SV40 large T antigen-induced primitive neuroectodermal tumors of the rat provide a model system to study induction and progression of primitive neuroectodermal tumors at the molecular level. A cell line derived from such a tumor reproducibly gave rise to malignant derivatives that ceased large T-antigen expression but harbored a mutant p53 allele with a common mutation at Cys(174) to Tyr (C174Y). To determine whether this p53 mutation contributes to tumor progression, we analyzed mutant C174Y functionally. Co-transfection experiments in Saos-2 cells with mutant or wild-type p53 and reporter genes linked to various p53-responsive promoters revealed that mutant C174Y failed to transcriptionally transactivate the Mdm2, Waf1, Cyclin G and Bax promoters. Loss of transcriptional activation correlated with loss of DNA-binding activity. Moreover, mutant C174Y exhibited a dominant negative effect on co-expressed wild-type p53. The ability of mutant p53 to repress the viral RSV, LTR or SV40 early promoters or the cellular fos promoter was likewise impaired. In contrast, it showed even induction of the fos promoter. Consistent with these observations, mutant C174Y was non-functional in the suppression of Saos-2 cell growth and even conferred a growth advantage to the cells. Surprisingly, mutant C174Y was also impaired in nuclear transport, as revealed by immunofluorescence analyses. Taken together, our results demonstrate that mutant C174Y possesses features that can positively contribute to cancer progression.
Perception for a river mapping robot (2011)

We consider the perceptual challenges inherent in the robotic manipulation of previously unseen socks, with the end goal of manipulation by a household robot for laundry. The task poses challenging problems in modeling the appearance, shape and configuration of these textile items that tend to exhibit high variability in texture, design, and style while being highly articulated objects.
Treatment effects produced by preorthodontic trainer appliance in patients with class II division I malocclusion (2010)

The aim of the present study was to evaluate cephalometrically the treatment effects of preorthodontic trainer on dentoskeletal components in individuals showing class II division I malocclusion. This study comprised of 50 class II div. I patients (20 test patients and 30 controls) in the age group of 8-12 years. The test group was treated with a preorthodontic trainer for a period of 15 months. Standardized lateral cephalograms of both groups were taken before and after the treatment period. The cephalograms were then evaluated to determine the skeletal and dental changes in the course of treatment and then compared with the normative growth data to eliminate the possible growth effects. The readings were tabulated and subjected to statistical analysis. The results of the study after excluding the changes due to growth showed reduction in ANB and OP-SN values, indicating a significant reduction in the skeletal class II relationship. An upward cant of the occlusal plane in the treatment group was noted, probably due to the forward rotation of mandible. A significant increase in the vertical dimensions of the face in general and the mandible in particular was observed with the use of preorthodontic trainer. A significant reduction in the overjet and an increase in the inclination of mandibular incisor (L1-NB deg) were noted in the treatment group when compared with control group. It can be concluded that class II corrections can be achieved with the preorthodontic trainer appliance, which appears to have mostly dentoalveolar effects with smaller but significant skeletal effects.

Electrohydrodynamic Enhancement of Heat Transfer for Developing Air Flow in Square Ducts (2005)

Corona discharge in air was used to generate a secondary flow that significantly improved the convective heat transfer coefficient in the developing region of a square duct. A wire electrode, charged with a high voltage, was placed at the center of the duct. The electrode ionized the air and created a corona current, which was measured experimentally and used in the computations. The conservation differential equations for flow, energy, and electric field were considered for the 3D flow in the developing region of the duct, and they were solved numerically. The computational results indicated that the secondary flow gradually evolves into a fully-developed eight-cell vortical structure that creates flow mixing and turbulence and enhances the heat transfer coefficient. In this study, the ranges of Reynolds number and applied voltage were 500–10,000 and 0–11.7 kV, respectively. The normalized Nusselt number, Nu/Nuo, ranged from 1.06 (Re = 10,000 and 8.1 kV) to 13.58 (Re = 2000 and 11.7 kV), but the pressure drop penalty was relatively low. The normalized friction factor, f/fo, ranged from 1.01 (Re = 10,000 and 8.1 kV) to 7.28 (Re = 2000 and 11.7 kV). The computations were verified by comparison with the published literature.
Interleukin-10 level in sputum is reduced in bronchial asthma, COPD and in smokers (1999)

Interleukin (IL)-10 is a potent regulatory cytokine that decreases inflammatory responses. This study investigated whether IL-10 levels in the airway are decreased in chronic airway inflammation associated with asthma or chronic obstructive pulmonary disease (COPD). Sputum was obtained from 12 healthy nonsmokers, 10 healthy smokers, 16 asthmatic patients and seven patients with COPD by means of the sputum-induction method. The IL-10 level was measured via enzyme-linked immunosorbent assay and immunocytochemical analysis. The IL-10 level in sputum was significantly lower in asthma and COPD patients and healthy smokers compared with that in healthy nonsmokers (nonsmokers, 68.0+/-11.3; smokers, 45.3+/-7.8; asthma, 26.7+/-4.0; COPD, 18.0+/-2.3 pg x mL(-1); p<0.05 for nonsmokers versus the other groups). The percentage of IL-10-positive cells in the sputum was also significantly lower in asthma and COPD and in smokers (nonsmokers, 13.2+/-1.7; smokers, 6.4+/-1.8; asthma, 5.4+/-3.5; COPD, 3.5+/-1.6%; p<0.05 for nonsmokers versus the other groups). The IL-10-positive cell appeared morphologically to be the macrophage. These data suggest that the reduced level of interleukin-10 within the airways plays a role in the pathogenesis of chronic airway inflammation in asthma and chronic obstructive pulmonary disease.
Accuracy of Liver Fat Quantification With Advanced CT, MRI, and Ultrasound Techniques: Prospective Comparison With MR Spectroscopy (2016)

Quantitative MRI proton-density fat fraction and SECT fat attenuation have excellent linear correlation with MRS measurements and can serve as accurate noninvasive biomarkers for quantifying steatosis. Material decomposition with DECT does not improve the accuracy of fat quantification over conventional SECT attenuation. US-SWE has poor accuracy for liver fat quantification.

Saccharomyces cerevisiae strains for second-generation ethanol production: from academic exploration to industrial implementation (2017)

The recent start-up of several full-scale 'second generation' ethanol plants marks a major milestone in the development of Saccharomyces cerevisiae strains for fermentation of lignocellulosic hydrolysates of agricultural residues and energy crops. After a discussion of the challenges that these novel industrial contexts impose on yeast strains, this minireview describes key metabolic engineering strategies that have been developed to address these challenges. Additionally, it outlines how proof-of-concept studies, often developed in academic settings, can be used for the development of robust strain platforms that meet the requirements for industrial application. Fermentation performance of current engineered industrial S. cerevisiae strains is no longer a bottleneck in efforts to achieve the projected outputs of the first large-scale second-generation ethanol plants. Academic and industrial yeast research will continue to strengthen the economic value position of second-generation ethanol production by further improving fermentation kinetics, product yield and cellular robustness under process conditions.

Structure‐staining relationships in histochemistry and biological staining (1980)

Correlations between the structural features of dyes and staining performance for elastic fibres were investigated. Dyes studied included the traditional stains (such as Gomori's Aldehyde-Fuchsin and Weigert's Resorcin-Fuchsin), acid dyes used from alkaline aqueous-organic solvent mixtures (the Horobin-James system), and basic dyes used from acidic aqueous-ethanolic mixtures (the Taenzer-Unna system). In all three classes effective elastic fibre stains had large conjugated bond numbers, and were often hydrophobic (i.e. had high Hansch pi values). By choosing dyes with conjugated bond numbers at or over a critical value (25 for the TU system, 35 for the HJ) it is possible to select new and effective dyes for use in the HJ and TU staining systems. Mechanistically these results support the view that for typical commercial dyes and also for the traditional stains van der Waals attractions provide the important contributions to dye-elastic fibre affinities, with hydrophobic bonding playing a subsidiary role. However, supporting the views of Lillie, it was also noted that even hydrophilic dyes of low conjugated bond number could stain elastic fibres, if the dye carried a sufficiently reactive primary amino group as a substituent. The additional substituent groupings needed to generate such reactivity have been specified, for both acidic and alkaline reaction conditions.
A short note on phase and amplitude tracking for seismic event separation (2015)

Summary We propose a method for decomposing a seismic record into atomic events defined by a smooth phase and a smooth amplitude. The method uses an iterative refinement-expansion tracking scheme to minimize the highly nonconvex objective function. We demonstrate the proposed method on a noisy synthetic record from the shallow Marmousi model. Finally, we show an application of our method to low frequency extrapolation on the same record. This note is a short version of Li and Demanet (2015).
Selective Generation of Gut‐Tropic T Cells in Gut‐Associated Lymphoid Tissues: Requirement for GALT Dendritic Cells and Adjuvant (2004)

To gain entry into peripheral tissues, effector T lymphocytes express specific combinations of adhesion molecules and chemokine receptors. Expression of these are induced during activation in regional secondary lymphoid organs. Herein, we describe a role for GALT DCs in the generation of CCR9(+) alpha(4)beta(7)(+) gut tropic lymphocytes.

USES OF SEAWEED AND ITS APPLICATION TO HUMAN WELFARE: A REVIEW (2016)

<p>Seaweed research has been carried out for more than seven decades by many research workers. Research has been done separately in different aspects accordingly to our need. The main objective of the present review is to gather information relating to nutritional, pharmacological, clinical, biochemical, industrial uses and its application to human welfare. Seaweeds have a high concentration of essential vitamins, trace elements, proteins, lipids, polysaccharides, enzymes, and minerals as compared to terrestrial foodstuffs. These plants have been a source of food, fodder, medicine, cosmetics, energy, fertilizer and are used for industrial production of agar and alginate. Their recent utilization increases in poultry due to their nutritive value. In the present scenario, it is being used for wastewater treatment such as treatment of wastewater to reduce nitrogen and phosphorus containing compounds. This review work is an attempt to highlights all the relevant application and uses of seaweeds and its products. Finally, this paper would be helpful to a common man to know and aware about such a great living resources which is present in and around us.<strong></strong></p>
Conservation and Variability of West Nile Virus Proteins (2009)

West Nile virus (WNV) has emerged globally as an increasingly important pathogen for humans and domestic animals. Studies of the evolutionary diversity of the virus over its known history will help to elucidate conserved sites, and characterize their correspondence to other pathogens and their relevance to the immune system. We describe a large-scale analysis of the entire WNV proteome, aimed at identifying and characterizing evolutionarily conserved amino acid sequences. This study, which used 2,746 WNV protein sequences collected from the NCBI GenPept database, focused on analysis of peptides of length 9 amino acids or more, which are immunologically relevant as potential T-cell epitopes. Entropy-based analysis of the diversity of WNV sequences, revealed the presence of numerous evolutionarily stable nonamer positions across the proteome (entropy value of < or = 1). The representation (frequency) of nonamers variant to the predominant peptide at these stable positions was, generally, low (< or = 10% of the WNV sequences analyzed). Eighty-eight fragments of length 9-29 amino acids, representing approximately 34% of the WNV polyprotein length, were identified to be identical and evolutionarily stable in all analyzed WNV sequences. Of the 88 completely conserved sequences, 67 are also present in other flaviviruses, and several have been associated with the functional and structural properties of viral proteins. Immunoinformatic analysis revealed that the majority (78/88) of conserved sequences are potentially immunogenic, while 44 contained experimentally confirmed human T-cell epitopes. This study identified a comprehensive catalogue of completely conserved WNV sequences, many of which are shared by other flaviviruses, and majority are potential epitopes. The complete conservation of these immunologically relevant sequences through the entire recorded WNV history suggests they will be valuable as components of peptide-specific vaccines or other therapeutic applications, for sequence-specific diagnosis of a wide-range of Flavivirus infections, and for studies of homologous sequences among other flaviviruses.
