Calcium sulfite hemihydrate: Crystal growth rate and crystal habit (1986)

Abstract The crystal growth rate of CaSO 3 · 1/2H 2 O was measured by a pH‐stat method in aqueous solution with pH 3.5 to 6.5, 1 to 25 mM dissolved sulfite, 0.01 to 0.3 M Ca ++ , and 0 to 25 mM sulfate. The growth rate was a strong function of relative supersaturation and was strongly inhibited by dissolved sulfate. The growth rate per unit BET surface area, R' (mole/cm 2 ‐min), is given by: 9.7 × 10 −4 exp (−10250/RT) × (RS CaSO 3 −1) 2 × RS CaSO4 −1 , where RS CaSO3 and RS CaSO4 are the relative saturations with respect to calcium sulfite and gypsum, respectively. Scanning electron microscopy and IR spectroscopy demonstrated that solids generated in the presence of dissolved sulfate contained solid solution sulfate and crystallized as agglomerates of very thin platelets. In the absence of solid or dissolved sulfate the solids were agglomerates of well‐informed columnar, hexagonal crystals.

A prototype demonstrates the application of blockchain in identity and access management using the Hyperledger Fabric framework. It provides a proof of concept based on a use case concerning Electronic Health Records from the healthcare domain where an immutable and auditable history is desired for data concerning patients. Basic authentication and authorization operations are able to execute in 2-3 seconds with an initial size of blockchain of about 3.8 MB covering physicians in Denmark.
Ikaros interacts with P-TEFb and cooperates with GATA-1 to enhance transcription elongation (2011)

Ikaros is associated with both gene transcriptional activation and repression in lymphocytes. Ikaros acts also as repressor of human γ-globin (huγ-) gene transcription in fetal and adult erythroid cells. Whether and eventually, how Ikaros can function as a transcriptional activator in erythroid cells remains poorly understood. Results presented herein demonstrate that Ikaros is a developmental-specific activator of huγ-gene expression in yolk sac erythroid cells. Molecular analysis in primary cells revealed that Ikaros interacts with Gata-1 and favors Brg1 recruitment to the human β-globin Locus Control Region and the huγ-promoters, supporting long-range chromatin interactions between these regions. Additionally, we demonstrate that Ikaros contributes to transcription initiation and elongation of the huγ-genes, since it is not only required for TBP and RNA Polymerase II (Pol II) assembly at the huγ-promoters but also for conversion of Pol II into the elongation-competent phosphorylated form. In agreement with the latter, we show that Ikaros interacts with Cyclin-dependent kinase 9 (Cdk9), which contributes to efficient transcription elongation by phosphorylating the C-terminal domain of the large subunit of Pol II on Serine 2, and favours Cdk9 recruitment to huγ-promoters. Our results show that Ikaros exerts dual functionality during gene activation, by promoting efficient transcription initiation and elongation.

TRDB--The Tandem Repeats Database (2006)

Tandem repeats in DNA have been under intensive study for many years, first, as a consequence of their usefulness as genomic markers and DNA fingerprints and more recently as their role in human disease and regulatory processes has become apparent. The Tandem Repeats Database (TRDB) is a public repository of information on tandem repeats in genomic DNA. It contains a variety of tools for repeat analysis, including the Tandem Repeats Finder program, query and filtering capabilities, repeat clustering, polymorphism prediction, PCR primer selection, data visualization and data download in a variety of formats. In addition, TRDB serves as a centralized research workbench. It provides user storage space and permits collaborators to privately share their data and analysis. TRDB is available at https://tandem.bu.edu/cgi-bin/trdb/trdb.exe.
Multiple UAVs mission assignment based on modified Pigeon-inspired optimization algorithm (2014)

Unmanned aerial vehicles (UAVs) have shown their superiority for applications in performing military and civilian missions. In which, multiple UAVs mission assignment is becoming more important for today's military activities. So far, there have been many bio-inspired computation algorithms for solving multiple UAVs mission assignment problems, including particle swarm optimization (PSO), differential evolution algorithm (DE) and so on. However, deficiencies of these approaches exist inevitably, which cannot satisfy the requirements of dynamic mission assignment. In this paper, a new UAV assignment model focusing on the energy consumption of UAV is brought up which can be easily applied to intelligence algorithms. Meanwhile, we propose a new approach by applying the modified Pigeon-Inspired Optimization (PIO) algorithm to sovle the multiple UAVs mission assignment problem. The simulation results show that the modified PIO algorithm is more effective when compared with other state-of-the-art algorithms in addressing mission assignment problem for multiple UAVs.

Application and evaluation of enzyme-linked immunosorbent assay and immunoblotting for detection of antibodies to<i>Treponema hyodysenteriae</i>in swine (1991)

An enzyme-linked immunoassay (ELISA) has been developed to detect serum Immunoglobulin antibodies G and M to Treponema hyodysenteriae in vaccinated, experimentally infected and naturally infected swine. Naturally infected swine gave ELISA titres that were similar to experimentally infected swine, but were significantly less than the titres of vaccinated swine. When serum from naturally infected swine was used to probe nitrocellulose blots of sodium dodecyl sulphate-polyacrylamide gel electrophoresed whole cell proteins of T. hyodysenteriae, the immunoblotting patterns showed IgG antibodies were produced against many T. hyodysenteriae protein antigens and against lipopolysaccharide (LPS). The IgG antibodies directed against LPS were serotype-specific for that LPS and could be used to identify the serotype involved in the T. hyodysenteriae infection in that herd. IgM immunoblots also reacted with the many protein antigens but were less specific for LPS antigen, with a substantial degree of cross-reaction between the LPS of all serotypes. The data demonstrate that a microplate enzyme-linked immunosorbent assay, coupled with immunoblotting, is a very specific and sensitive test for detection of antibody to Treponema hyodysenteriae in swine.

Carbonate Precipitation through Microbial Activities in Natural Environment, and Their Potential in Biotechnology: A Review (2016)

Calcium carbonate represents a large portion of carbon reservoir and is used commercially for a variety of applications. Microbial carbonate precipitation (MCP), a by-product of microbial activities, plays an important metal coprecipitation and cementation role in natural systems. This natural process occurring in various geological settings can be mimicked and used for a number of biotechnology such as metal remediation, carbon sequestration, enhanced oil recovery and construction restoration. In this study, different metabolic activities leading to calcium carbonate precipitation, their native environment, and potential applications and challenges are reviewed.
Detecting Fatigue From Voice Using Speech Recognition (2006)

Military and civilian experience has shown that long-duration assignments present increased risk of performance failures as the mission progresses. This is due to interruption of normal sleep cycles and psychological pressures of the work environment. There continues to be a need for a non-intrusive fatigue assessment system to successfully monitor the level of alertness of personnel during critical missions and activities. Experimental results on human voice show that specific phones have a predictable dependence on fatigue. Hence, precise phonetic identification and alignment are important to voice-based fatigue detection. This paper explores techniques for detecting fatigue from voice using speech recognition to obtain phonetic alignments. A confidence measure was used to filter out less likely word hypotheses from the ASR's output. In this paper we restricted our analysis to dealing with out-of-vocabulary words. The results obtained from voice show strong correlation with other standardized tests such as sleep onset latency and sleep, activity, fatigue, and task effectiveness
Synthesis and Biological Activities of New HMG-CoA Synthase Inhibitors: 2-Oxetanones with a Side Chain Containing Biphenyl, Terphenyl or Phenylpyridine (1994)

A series of 1233A analogs containing biphenylyl, terphenylyl or phenylpyridyl groups in their side chain were synthesized and tested for the inhibitory activities against 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthase and inhibition for the cholesterol biosynthesis in the mouse liver. The compounds with an oxetane, cyclobutanone or γ-butyrolactone ring as isosters of a 2-oxetanone ring were entirely inactive. Among synthetic analogs, anti-4-[3-[2-(5-isopropyl-2-pyridyl)-ethyl]-phenyl]ethyl]-3hydroxymethyl-2-oxetanone (10b) was most active in vitro. The structure activity relationships on the transformations of 2-oxetanone and its side chain were obtained
Polymorphisms of glutathione S-transferases (GST) and thymidylate synthase (TS) – novel predictors for response and survival in gastric cancer patients (2005)

To evaluate the predictive value of a panel of gene polymorphisms involved in metabolism of 5-FU and cisplatin on clinical outcome in advanced gastric cancer patients. A total of 52 patients were enrolled in this study. DNA was extracted from paraffin-embedded tumour specimen. Genotypes were determined using PCR-RFLP. Median survival time was 6.0 months (95% CI 3.9;8.1). Overall response rate was 26%. Patients possessing the glutathione S-transferase P1-105 Valine/Valine (GSTP1-105VV) genotype showed a response rate of 67% compared to 21% in patients harbouring at least one GSTP1-105 Isoleucine (GSTP1-105I) allele (P=0.038). GSTP1-105VV patients demonstrated a significant superior median survival time of 15.0 months (95% CI 7.8;22.0) compared to 6.0 months (95% CI 5.1;7.0) in patients with at least one GSTP1-105I allele (P=0.037). Patients possessing a favourable thymidylate synthase (TS) genotype (2R/2R, 2R/3RC, 3RC/3RC) experienced a superior survival time of 10.2 months (95% CI 5.1;15.3) compared to 6.0 months (95% CI 5.0;7.0) in patients with unfavourable TS genotypes (P=0.099). Patients harbouring the GSTP1-105II genotype and one of the unfavourable TS genotypes showed an inferior median survival time of 6.0 months (95% CI 3.9;8.1) compared to 11 months (95% CI 6,23;15,77) in patients with either GSTP1-105VV or a favourable TS genotype (P=0.044). Testing for TS and GSTP1 polymorphisms may allow identification of gastric cancer patients who will benefit from 5-FU/cisplatin chemotherapy, sparing others the side effects of this chemotherapy.
Synthesis of Nickel Nanoparticles Supported on Nanoporous Silicon Oxycarbide (SiCO) Sheath−Core Fibers (2010)

Nickel (Ni) nanoparticles with average diameters less than 5 nm were successfully synthesized on nanoporous silicon oxycarbide (SiCO) sheath−core fibers by incipient wetness impregnation of Ni acetylacetonate precursor followed by reduction at temperatures above 250 °C. The SiCO fibers were fabricated by pyrolyzing electrospun 5/15 PUS/PMMA composite fibers at temperatures from 250 to 1000 °C to contain nanoporous cores and striated sheaths. The SiCO fibers pyrolyzed up to 600 °C were superhydrophobic and became superhydrophilic when pyrolyzed at 800 °C and above. Such a drastic switch from superhydrophobicity to superhydrophilicity coincided with the disappearance of aliphatic methyl and methylene groups. The SiCO ceramic fibers pyrolyzed at 1000 °C were highly porous with BET surface area 95.7 m2/g, pore volume 0.352 cm3/g, and average pore size 26 nm. They were thermally and chemically stable enough to support the Ni acetylacetonate precursor to be reduced to Ni nanoparticles at 250, 500, and 900 °C. SEM observation and EDS elemental mappings showed the reduced Ni nanoparticles to be homogeneously distributed in the fibrous structures without any aggregation. The Ni nanoparticles were monodispersed as confirmed by TEM and in a face-centered-cubic crystalline structure as evidenced by SAED and XRD.
The 9-Å solution: How mRNA pseudoknots promote efficient programmed −1 ribosomal frameshifting (2003)

There is something special about mRNA pseudoknots that allows them to elicit efficient levels of programmed -1 ribosomal frameshifting. Here, we present a synthesis of recent crystallographic, molecular, biochemical, and genetic studies to explain this property. Movement of 9 A by the anticodon loop of the aminoacyl-tRNA at the accommodation step normally pulls the downstream mRNA a similar distance along with it. We suggest that the downstream mRNA pseudoknot provides resistance to this movement by becoming wedged into the entrance of the ribosomal mRNA tunnel. These two opposing forces result in the creation of a local region of tension in the mRNA between the A-site codon and the mRNA pseudoknot. This can be relieved by one of two mechanisms; unwinding the pseudoknot, allowing the downstream region to move forward, or by slippage of the proximal region of the mRNA backwards by one base. The observed result of the latter mechanism is a net shift of reading frame by one base in the 5' direction, that is, a -1 ribosomal frameshift.

Persistent Scatterer Interferometry (2010)

This paper is focused on the potential and limits of Persistent Scatterer Interferometry (PSI), a powerful remote sensing technique used to measure deformation phenomena. It only refers to satellite-based PSI techniques, focusing on the most important sources of C-band SAR data: ERS and Envisat. In addition, it compares C- and X-band results, considering data from the high-resolution TerraSAR-X sensor. The paper begins with a description of the main characteristics of PSI. It then discusses the most important PSI products and their performances, analyzing their spatial sampling, the so-called residual topographic error and PSI geocoding, the average displacement rates, and the deformation time series. As C-band products are concerned, the paper reports some relevant PSI validation results, which come from the ESA-funded Terrafirma Validation Project. Regarding the X-band, it describes the results obtained over the City of Barcelona by processing 13 TerraSAR-X images. The last part discusses the main limits of PSI.
Studies on Leucocyte Function by Measuring Respiration and Nitroblue Tetrazolium Reduction by Simplified Methods (1973)

Two modified tests for evaluating leucocyte metabolic characteristics, i.e. oxygen consumption rate and nitroblue tetrazolium reduction capacity in the absence and presence of phagocytogenic agents, are presented here. Oxygen consumption was measured using hemoglobin as indicator of oxygen tension, which is thus recorded spectro-photometrically. The assay of nitroblue tetrazolium reduction capacity was simplified, thus permitting higher testing capacity. The methods were evaluated on a family including three members suffering from chronic granulomatous disease. Affected individuals did not show the normal respiratory burst in conjunction with phagocytosis nor did they reduce nitroblue tetrazolium.
Kinematics and open-loop control of an ilonator-based mobile platform (2005)

This paper describes the analysis and implementation of a motor drive control system for an intelligent wheelchair being developed at the Robotics Institute at Carnegie-Mellon University. The experimental mobile platform is mounted on four so-called Ilonators which permit motion in any direction without conventional steering of the wheel axes. The kinematics of the platform were determined analytically and a simulation program was developed to generate reference wheel velocity trajectories corresponding to several basic platform trajectories. These reference trajectories were used to drive the platform under open-loop control. The paper includes a description of the motor-drive hardware implementation, and experimental results. The results of this work provide the foundation for the implementation of feedback control of the wheels and higher-level supervisory control.
