Characterization of Direct Push Vadose Zone Sediments from the T and TY Waste Management Areas (2007)

This report contains all the geochemical and selected physical characterization data collected on vadose zone sediment recovered from 5 direct push characterization holes emplaced to investigate vadose zone contamination associated with leaks from tanks 241-TY-105 (UPR-200-W-152) and 241-TY-106 (UPR-200-W-153). Tank 241-TY-105 is estimated to have leaked 35,000 gal of tributyl phosphate (TBP) waste from the uranium recovery process to the vadose zone in 1960. Tank 241-TY-106 is estimated to have leaked 20,000 gal of TBP-uranium recovery waste to the vadose zone in 1959. Although several drywells in the vicinity of tank 241-TY-106 contain measurable quantities of cesium-137 and/or cobalt-60, their relatively low concentrations indicate that the contaminant inventory in the vadose zone around tank 241-TY-106 is quite small. Additionally, this report contains all the geochemical and selected physical characterization data collected on vadose zone sediment recovered from 7 direct push characterization holes emplaced to investigate vadose zone contamination associated with an overfill event and leak from tank 241-T-101.
Identification and Characterization of RbmA, a Novel Protein Required for the Development of Rugose Colony Morphology and Biofilm Structure in Vibrio cholerae (2006)

Phase variation between smooth and rugose colony variants of Vibrio cholerae is predicted to be important for the pathogen's survival in its natural aquatic ecosystems. The rugose variant forms corrugated colonies, exhibits increased levels of resistance to osmotic, acid, and oxidative stresses, and has an enhanced capacity to form biofilms. Many of these phenotypes are mediated in part by increased production of an exopolysaccharide termed VPS. In this study, we compared total protein profiles of the smooth and rugose variants using two-dimensional gel electrophoresis and identified one protein that is present at a higher level in the rugose variant. A mutation in the gene encoding this protein, which does not have any known homologs in the protein databases, causes cells to form biofilms that are more fragile and sensitive to sodium dodecyl sulfate than wild-type biofilms. The results indicate that the gene, termed rbmA (rugosity and biofilm structure modulator A), is required for rugose colony formation and biofilm structure integrity in V. cholerae. Transcription of rbmA is positively regulated by the response regulator VpsR but not VpsT.
Model Transformation Contracts and their Definition in UML and OCL (2004)

Abstract. A major challenge of the OMG Model-Driven Architecture (MDA) initiative is to be able to define and execute transformations of models. Such transformations may be defined in several ways and with various motivations. Our motivation is to specify model transformations independently of any transformation technology. To achieve this goal, we propose to define transformation contracts. We argue that model transformation contracts are an essential basis for the MDA, they can be used for specification, validation and test of transformations. This paper focuses on model transformation contract specification. We investigate the way to define them using standard UML and OCL features. In addition to presenting the approach and some experimental results, this paper discusses some limits of standard OCL to define transformation contracts as well as some hints to bypass these limitations. 1
The Near-Surface Circulation of the Eastern North Pacific (1978)

A description of the near-surface circulation of the eastern North Pacific during 1976–77 is given. The data for the study are obtained from 23 satellite (Nimbus 6) tracked drifters. The large-scale description obtained from the drifter trajectories is in good agreement with the mean annual dynamic topography. In the interior there is eastward zonal flow with a pronounced northward meander centered around 140°W. It is speculated that the meander, which is also seen in the mean annual dynamic topography, is an occasional feature closely connected with large-scale fluctuations of the surface wind. The trajectories define the eastern portion of the subarctic and subtropical gyres and the split between these gyres which occurs at about 50°N. In addition to these large-scale features, the trajectories show ubiquitous mesoscale activity. However, the mesoscale velocity field is not as strong as that reported for the western Atlantic or western Pacific. Separation statistics for the drifters indicate that very little dispersion occurs on time scales longer than 30 days and space scales greater than 300 km.
Enzymatic production of fully deacetylated chitooligosaccharides and their neuroprotective and anti-inflammatory properties (2017)

Among several commercial enzymes screened for chitosanolytic activity, Neutrase 0.8L (a protease from Bacillus amyloliquefaciens) was selected in order to obtain a product enriched in deacetylated chitooligosaccharides (COS). The hydrolysis of different chitosans with this enzyme was followed by size exclusion chromatography (SEC-ELSD), mass spectrometry (ESI-Q-TOF), and high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD). Neutrase 0.8L converted 10 g/L of various chitosans into mostly deacetylated oligosaccharides, yielding approximately 2.5 g/L of chitobiose, 4.5 g/L of chitotriose, and 3 g/L of chitotetraose. We found out that the neutral protease was not responsible for the chitosanolytic activity in the extract, while it could participate in the deacetylating process. The synthesized COS were tested in vitro for their neuroprotective (toward human SH-S5Y5 neurons) and anti-inflammatory (in RAW macrophages) activities, and compared with other functional ingredients, namely fructooligosaccharides.
Fatty acid composition of rice lipids by gas‐liquid chromatography (1964)

Abstract Gas‐liquid Chromatographic analysis of the methyl ester of lipids of four rice varieties showed that bran lipids had significantly higher mean contents of linoleic and linolenic acids, but lower contents of myristic, palmitic, palmitoleic, and stearic acids than milled rice lipids. Nine fatty acids were detected. The principal components were oleic, linoleic, and palmitic, which also was confirmed by thin‐layer chromatography of the esters.

Coordination Chemistry of Ir with Chelating Ligands Containing a Xanthine‐Derived, Protic N‐Heterocyclic Carbene (NHC) Moiety (2022)

Abstract A series of protic N‐heterocyclic carbene ligand precursors based on theophylline or adenine has been prepared, and the reactivity and coordination chemistry of these proligands towards iridium(III) centers has been investigated. Complex formation appears to be highly dependent on the proligand structure. In one case, a particularly stable complex is formed that enables fully reversible protonation/deprotonation of the coordinated NHC moiety. The acidity constant of the protonated complex was consequently determined.
Green, formaldehyde-free, foams for thermal insulation (2011)

New, green and cheap rigid foams presenting outstanding performances for thermal insulation are described. Such ultra-lightweight cellular materials are mainly based on renewable chemicals: tannin and furfuryl alcohol, are very easy to produce and have thermal conductivity as low as 38 mW/m/K. Compared to previously reported tannin-based foams, these new materials are much “greener” and present improved resistance to compression and to water. Especially the formaldehyde, formerly used as cross-linking agent of tannins but known as a volatile and harmful chemical, could be successfully removed from the formulation. The as-obtained, 2nd generation, tannin-based foams are totally stable and have an expected interest for thermal insulation of buildings.
Investigation on cascade multilevel inverter with symmetric, asymmetric, hybrid and multi-cell configurations (2016)

In recent past, numerous multilevel architectures came into existence. In this background, cascaded multilevel inverter (CMLI) is the promising structure. This type of multilevel inverters synthesizes a medium voltage output based on a series connection of power cells which use standard low-voltage component configurations. This characteristic allows one to achieve high-quality output voltage and current waveforms. However, when the number of levels increases switching components and the count of dc sources are also increased. This issue became a key motivation for the present paper. The present paper is devoted to investigate different types of CMLI which use less number of switching components and dc sources and finally proposed a new version of Multi-cell based CMLI. In order to verify the proposed topology, MATLAB – simulations and hardware verifications are carried out and results are presented.

Equivalence of magnetic field and particle dilution in the strange metal state of CeCoIn$_5$ (2018)

The Bardeen-Cooper-Schrieffer mechanism for superconductivity is a triumph of the theory of many-body systems. Implicit in its formulation is the existence of long-lived (quasi)particles, originating from the electronic building blocks of the materials, which interact to form Cooper pairs that move coherently in lock-step. The challenge of unconventional superconductors is that it is not only unclear what the nature of the interactions are, but whether the familiar quasi-particles that form a superconducting condensate even exist. In this work, we reveal, by the study of applied magnetic field in electronically diluted materials, that the metallic properties of the unconventional superconductor CeCoIn$_5$ are determined by the degree of quantum entanglement that (Kondo) hybridizes local and itinerant electrons. This work suggests that the properties of the strange metallic state are a reflection of the disentanglement of the many-body state into the underlying electronic building blocks of the system itself.

Decision Tree Based Predictive Models for Breast Cancer Survivability on Imbalanced Data (2009)

Based on imbalanced data, the predictive models for 5-year survivability of breast cancer using decision tree are proposed. After data preprocessing from SEER breast cancer datasets, it is obviously that the category of data distribution is imbalanced. Under-sampling is taken to make up the disadvantage of the performance of models caused by the imbalanced data. The performance of the models is evaluated by AUC under ROC curve, accuracy, specificity and sensitivity with 10-fold stratified cross-validation. The performance of models is best while the distribution of data is approximately equal. Bagging algorithm is used to build an integration decision tree model for predicting breast cancer survivability.
The Independent cue and cusSystems Confer Copper Tolerance during Aerobic and Anaerobic Growth inEscherichia coli (2001)

Copper is essential but can be toxic even at low concentrations. Coping with this duality requires multiple pathways to control intracellular copper availability. Three copper-inducible promoters, controlling expression of six copper tolerance genes, were recently identified in Escherichia coli. The cue system employs an inner membrane copper transporter, whereas the cus system includes a tripartite transporter spanning the entire cell envelope. Although cus is not essential for aerobic copper tolerance, we show here that a copper-sensitive phenotype can be observed when cus is inactivated in a cueR background. Furthermore, a clear copper-sensitive phenotype for the cus system is revealed in the absence of O(2). These results indicate that the cue pathway, which includes a copper exporter, CopA, and a periplasmic oxidase, CueO, is the primary aerobic system for copper tolerance. During anaerobic growth, however, copper toxicity increases, and the independent cus copper exporter is also necessary for full copper tolerance. We conclude that the cytosolic (CueR) and periplasmic (CusRS) sensor systems differentially regulate copper export systems in response to changes in copper and oxygen availability. These results underscore the increased toxicity of copper under anaerobic conditions and the complex adaptation of copper export in E. coli.

Three New Quassinoids, Ailantinol E, F, and G, from Ailanthus altissima. (2003)

Three new quassinoids, ailantinol E (1), ailantinol F (2), and ailantinol G (3), and related compounds were isolated from Ailanthus altissima grown in Taiwan. Their structures were elucidated from spectral evidence. Each new quassinoid was evaluated for its antitumor promoting effects against Epstein-Barr virus early antigen activation introduced by 12-O-tetradecanoylphorbol-13-acetate in Raji cells. The new quassinoids were found to show potent activity without showing any cytotoxicity. The screening for inhibitors against nitric oxide donor action was also conducted using the new quassinoids and some standard samples.
Visual Analytics for Deep Embeddings of Large Scale Molecular Dynamics Simulations (2019)

Abstract Molecular Dynamics (MD) simulation have been emerging as an excellent candidate for understanding complex atomic and molecular scale mechanism of bio-molecules that control essential bio-physical phenomenon in a living organism. But this MD technique produces large-size and long-timescale data that are inherently high-dimensional and occupies many terabytes of data. Processing this immense amount of data in a meaningful way is becoming increasingly difficult. Therefore, specific dimensionality reduction algorithm using deep learning technique has been employed here to embed the high-dimensional data in a lower-dimension latent space that still preserves the inherent molecular characteristics i.e. retains biologically meaningful information. Subsequently, the results of the embedding models are visualized for model evaluation and analysis of the extracted underlying features. However, most of the existing visualizations for embeddings have limitations in evaluating the embedding models and understanding the complex simulation data. We propose an interactive visual analytics system for embeddings of MD simulations to not only evaluate and explain an embedding model but also analyze various characteristics of the simulations. Our system enables exploration and discovery of meaningful and semantic embedding results and supports the understanding and evaluation of results by the quantitatively described features of the MD simulations (even without specific labels).
Spot evolution on LQ Hya from 2006–2017: temperature maps based on SOFIN and FIES data (2019)

Context. LQ Hya is one of the most frequently studied young solar analogue stars. Recently, it has been observed to show intriguing behaviour when analysing long-term photometry. For instance, from 2003–2009, a coherent spot structure migrating in the rotational frame was reported by various authors. However, ever since, the star has entered a chaotic state where coherent structures seem to have disappeared and rapid phase jumps of the photometric minima occur irregularly over time. Aims. LQ Hya is one of the stars included in the SOFIN/FIES long-term monitoring campaign extending over 25 yr. Here, we publish new temperature maps for the star during 2006–2017, covering the chaotic state of the star. Methods. We used a Doppler imaging technique to derive surface temperature maps from high-resolution spectra. Results. From the mean temperatures of the Doppler maps, we see a weak but systematic increase in the surface temperature of the star. This is consistent with the simultaneously increasing photometric magnitude. During nearly all observing seasons, we see a high-latitude spot structure which is clearly non-axisymmetric. The phase behaviour of this structure is very chaotic but agrees reasonably well with the photometry. Equatorial spots are also frequently seen, but we interpret many of them to be artefacts due to the poor to moderate phase coverage. Conclusions. Even during the chaotic phase of the star, the spot topology has remained very similar to the higher activity epochs with more coherent and long-lived spot structures. In particular, we see high-latitude and equatorial spot activity, the mid latitude range still being most often void of spots. We interpret the erratic jumps and drifts in phase of the photometric minima to be caused by changes in the high-latitude spot structure rather than the equatorial spots.
Relative roles of the pituitary, follicle cells, and progesterone in the induction of oocyte maturation in Rana pipiens (1967)

Abstract The responses of ovarian oocytes obtained from mature frogs ( Rana pipiens ) to pituitary hormone were examined after removal of the follicular envelope. When the follicular envelope was removed manually or after treatment with collagenase, the apparently naked oocyte can still respond to pituitary hormone by germinal vesicle breakdown and by polar body formation. However, when the follicular envelope was removed after treatment with EDTA or Ca‐Mg‐free solution, the responsiveness of the oocyte was completely lost. Microscopic examination revealed that removal of the follicular cells was incomplete unless Ca‐Mg‐free solutions or EDTA were used. Complete removal of follicle cells prevents the oocyte from responding to pituitary hormone. Moreover, the naked oocytes packed together with previously separated follicular envelopes showed maturation responses when treated with pituitary hormone solution in the presence of large amounts of ovarian tissue. Naked oocytes which are unable to respond to pituitary hormone can nevertheless full respond to progesterone to undergo maturation reactions. In fact, germinal vesicle berakdown and polar body formation were brought about within intact ovarian tissue by treatment with progesterone alone. Oocytes responding to progesterone alone always remained within the follicular envelope. The degree of maturation of the oocytes after progesterone treatment was tested by means of nuclear transplantation. When nuclei obtained from blastula or early gastrula cells were implanted into treated oocytes, still within the follicular envelope, normal cleavage occurred. These results indicate that pituitary gonadotropin acts on the follicle cells to stimulate them to release a hormone that directly acts on the oocyte to induce maturation.
Basic level scene understanding (2012)

An early goal of computer vision was to build a system that could automatically understand a 3D scene just by looking. This requires not only the ability to extract 3D information from image information alone, but also to handle the large variety of different environments that comprise our visual world. This paper summarizes our recent efforts toward these goals. First, we describe the SUN database, which is a collection of annotated images spanning 908 different scene categories. This database allows us to systematically study the space of possible everyday scenes and to establish a benchmark for scene and object recognition. We also explore ways of coping with the variety of viewpoints within these scenes. For this, we have introduced a database of 360° panoramic images for many of the scene categories in the SUN database and have explored viewpoint recognition within the environments. Finally, we describe steps toward a unified 3D parsing of everyday scenes: (i) the ability to localize geometric primitives in images, such as cuboids and cylinders, which often comprise many everyday objects, and (ii) an integrated system to extract the 3D structure of the scene and objects depicted in an image.
Design and Performance of a Minimum-Variance Hybrid Location Algorithm Utilizing GPS and Cellular Received Signal Strength for Positioning in Dense Urban Environments (2009)

This paper shows how the complementary advantages of
GPS and cellular received signal strength (RSS)
positioning methods improves hybrid location estimation
performance in dense urban environments. In general,
GPS techniques work best in rural or suburban
environments where there is only moderate building or
landscape clutter to interrupt sky visibility or to introduce multipath errors from reflected satellite signals. In contrast, cellular techniques work best in urban
environments where the density and geometry of cell
towers is favorable. Test results show that cellular-RSS effectively can be used to eliminate GPS outliers (location errors > 1 km, such as those associated with cell-ID fallback mode), while GPS can improve the accuracy of the combined solution. Based on field trial data, the accuracy of the Minimum-Variance Hybrid Algorithm (in dense urban
environments) is approximately 45m for 67% of E911
calls and 110m for 95% of E911 calls.
