Mineral Reactions in Shale Gas Reservoirs: Barite Scale Formation from Reusing Produced Water As Hydraulic Fracturing Fluid (2017)

Hydraulic fracturing for gas production is now ubiquitous in shale plays, but relatively little is known about shale-hydraulic fracturing fluid (HFF) reactions within the reservoir. To investigate reactions during the shut-in period of hydraulic fracturing, experiments were conducted flowing different HFFs through fractured Marcellus shale cores at reservoir temperature and pressure (66 °C, 20 MPa) for one week. Results indicate HFFs with hydrochloric acid cause substantial dissolution of carbonate minerals, as expected, increasing effective fracture volume (fracture volume + near-fracture matrix porosity) by 56-65%. HFFs with reused produced water composition cause precipitation of secondary minerals, particularly barite, decreasing effective fracture volume by 1-3%. Barite precipitation occurs despite the presence of antiscalants in experiments with and without shale contact and is driven in part by addition of dissolved sulfate from the decomposition of persulfate breakers in HFF at reservoir conditions. The overall effect of mineral changes on the reservoir has yet to be quantified, but the significant amount of barite scale formed by HFFs with reused produced water composition could reduce effective fracture volume. Further study is required to extrapolate experimental results to reservoir-scale and to explore the effect that mineral changes from HFF interaction with shale might have on gas production.
Odor Recognition Memory as a Function of Odor-Naming Performance (2010)

A series of experiments sought to clarify the relationship between odor naming and memory by manipulating odor label availability during a dual naming-memory task. Experiment 1 demonstrated that recognition memory and odor naming were both better when the naming task provided participants with odor label alternatives. Consistent and correct odor naming was associated with nearly perfect memory, whereas inconsistent or incorrect naming was associated with very weak memory if any at all. Experiment 2 showed that the availability of odor labels was effective at improving memory only if labels were available at both memory encoding and retrieval, suggesting that the labels were aiding memory by improving the identification of the odors. Odor naming was manipulated in Experiment 3 by varying the number of available labels from 4 to 16 during each odor-naming trial. As found in the previous experiments, naming and memory were strongly related in each of the labeling conditions. Experiment 4 showed that corrective naming feedback produced better memory performance but only when the feedback led to correct odor naming. It was concluded that perceptual processes related to matching olfactory input to acquired, multidimensional representations of odors play a critical role in both odor naming and episodic memory.
Effects of Various Types of Aluminosilicates and Aflatoxin B1 on Aflatoxin Toxicity, Chick Performance, and Mineral Status (1993)

In vivo and in vitro trials were conducted to test the efficacy of four aluminosilicates (AS) (Ethacal feed component, Novasil, Perlite, and Zeobrite) to sorb aflatoxin B1 (AFB1) and alleviate aflatoxicosis in broiler chicks. Percentage sorption capacity of AS to radiolabeled AFB1 dissolved in methanol varied from 2 to 60%, whereas percentage sorption in intestinal contents varied from 0 to 40.0% according to type of AS tested. Intestinal contents alone sorbed 42% radiolabeled AFB1. Novasil and Zeobrite exhibited the highest rates of sorption (55 and 60%, respectively) in methanol. An in vivo study compared the four types of AS in combination with 0 or 2.5 ppm AFB1 fed to day-old chicks (two pens of six chicks per treatment) to 3 wk of age. Diet effects on body weight, liver lipid, bone ash, and serum Ca, P, Na, K, and Cl were measured. The AFB1 significantly decreased 2- and 3-wk body weight, and a significant interaction effect of AS and AFB1 on bird weight occurred at 2 and 3 wk of age. Three of the four AS tested alleviated the growth depression caused by AFB1. Liver lipids percentage was increased in the AFB1-treated chicks, but this effect was suppressed by three of the AS. Bone ash was not affected by AFB1 and was increased by Novasil and decreased by Ethacal. Ethacal, Novasil, Perlite, and Zeobrite all tended to decrease serum Cl, regardless of AFB1 treatment.

Induction of β3-Integrin Gene Expression by Sustained Activation of the Ras-Regulated Raf–MEK–Extracellular Signal-Regulated Kinase Signaling Pathway (2001)

Alterations in the expression of integrin receptors for extracellular matrix (ECM) proteins are strongly associated with the acquisition of invasive and/or metastatic properties by human cancer cells. Despite this, comparatively little is known of the biochemical mechanisms that regulate the expression of integrin genes in cells. Here we demonstrate that the Ras-activated Raf-MEK-extracellular signal-regulated kinase (ERK) signaling pathway can specifically control the expression of individual integrin subunits in a variety of human and mouse cell lines. Pharmacological inhibition of MEK1 in a number of human melanoma and pancreatic carcinoma cell lines led to reduced cell surface expression of alpha6- and beta3-integrin. Consistent with this, conditional activation of the Raf-MEK-ERK pathway in NIH 3T3 cells led to a 5 to 20-fold induction of cell surface alpha6- and beta3-integrin expression. Induced beta3-integrin was expressed on the cell surface as a heterodimer with alphav-integrin; however, the overall level of alphav-integrin expression was not altered by Ras or Raf. Raf-induced beta3-integrin was observed in primary and established mouse fibroblast lines and in mouse and human endothelial cells. Consistent with previous reports of the ability of the Raf-MEK-ERK signaling pathway to induce beta3-integrin gene transcription in human K-562 erythroleukemia cells, Raf activation in NIH 3T3 cells led to elevated beta3-integrin mRNA. However, unlike immediate-early Raf targets such as heparin binding epidermal growth factor and Mdm2, beta3-integrin mRNA was induced by Raf in a manner that was cycloheximide sensitive. Surprisingly, activation of the Raf-MEK-ERK signaling pathway by growth factors and mitogens had little or no effect on beta3-integrin expression, suggesting that the expression of this gene requires sustained activation of this signaling pathway. In addition, despite the robust induction of cell surface alphavbeta3-integrin expression by Raf in NIH 3T3 cells, such cells display decreased spreading and adhesion, with a loss of focal adhesions and actin stress fibers. These data suggest that oncogene-induced alterations in integrin gene expression may participate in the changes in cell adhesion and migration that accompany the process of oncogenic transformation.
SUSCEPTIBILITY EPITOPE ON HLA‐DR β CHAIN FOR RHEUMATOID ARTHRITIS AND THE EFFECT OF THE POSITIVITY ON THE CLINICAL FEATURES (1989)

A highly significant association of an amino acid sequence, '70Q71R72R73A74A' located on the DR beta-1 chain, with rheumatoid arthritis (RA) was confirmed in Japanese patients using polymerase chain reaction. The '70QRRA74A' is the most plausible candidate of susceptibility epitope in Japanese RA patients. The patients carrying the sequence showed slightly higher but not significant familial incidence. The positivity of the 'QRRAA' showed no effect on the positivity of the rheumatoid factor, rheumatoid nodules, and extra-articular signs. Also no significant differences in other clinical parameters (ESR, CRP, Hb, A/G) and age at onset were observed regarding the positivity. The risk that the 'QRRAA' positive subjects would suffer from RA was estimated to be about 1.3% which meant 7.2 times easier to get RA than those without 'QRRAA'.

Implication of non-NMDA and NMDA receptors in cochlear ischemia (1992)

We have investigated the hypothesis that the acute ischemic swelling of the radial dendrites connected to the inner hair cells (IHCs) is mediated by glutamatergic receptors. In control cochleas, after 20 min ischemia all the dendrites were dramatically swollen. Conversely, after a perfusion of 50 microM 6-7-dinitroquinoxaline-2,3-dione (DNQX) before ischemia, most dendrites were protected although those contacting the IHCs on their modiolar side frequently swelled. After 50 microM of D-2-amino-5-phosphonopentanoate (D-AP5), no dendrite protection could be obtained. Finally, after DNQX and D-AP5, no dendrite swelling occurred. These results suggest that, in the cochlea, the acute ischemic swelling of dendrites primarily occurs via non-NMDA receptors. However, in radial dendrites contacting the IHCs on their modiolar side, NMDA receptors may contribute to excitotoxicity.
Deep Visual Reasoning: Learning to Predict Action Sequences for Task and Motion Planning from an Initial Scene Image (2020)

In this paper, we propose a deep convolutional recurrent neural network that predicts action sequences for task and motion planning (TAMP) from an initial scene image. Typical TAMP problems are formalized by combining reasoning on a symbolic, discrete level (e.g. first-order logic) with continuous motion planning such as nonlinear trajectory optimization. Due to the great combinatorial complexity of possible discrete action sequences, a large number of optimization/motion planning problems have to be solved to find a solution, which limits the scalability of these approaches.
Small Molecule Inhibitors of a Glycoside Hydrolase Attenuate Inducible AmpC-mediated β-Lactam Resistance (2007)

The increasing spread of plasmid-borne ampC-ampR operons is of considerable medical importance, since the AmpC beta-lactamases they encode confer high level resistance to many third generation cephalosporins. Induction of AmpC beta-lactamase from endogenous or plasmid-borne ampC-ampR operons is mediated by a catabolic inducer molecule, 1,6-anhydro-N-acetylmuramic acid (MurNAc) tripeptide, an intermediate of the cell wall recycling pathway derived from the peptidoglycan. Here we describe a strategy for attenuating the antibiotic resistance associated with the ampC-ampR operon by blocking the formation of the inducer molecule using small molecule inhibitors of NagZ, the glycoside hydrolase catalyzing the formation of this inducer molecule. The structure of the NagZ-inhibitor complex provides insight into the molecular basis for inhibition and enables the development of inhibitors with 100-fold selectivity for NagZ over functionally related human enzymes. These PUGNAc-derived inhibitors reduce the minimal inhibitory concentration (MIC) values for several clinically relevant cephalosporins in both wild-type and AmpC-hyperproducing strains lacking functional AmpD.
Magnetization and Hysteresis in Hematite Crystals (1920)

Magnetization and Hysteresis in Hematite Crystals; Experimental Procedure.---In a previous paper, the author has given the results of an investigation of the magnetic properties of crystallized hematite, the measurements being of the force exerted upon a sphere when it is placed in a non-uniform magnetic field. The present paper contains some results obtained by measuring the couple exerted when a hematite sphere is suspended in a uniform magnetic field. The couple in a uniform field measures the component of magnetization perpendicular to the field; the force measures the component parallel to the field.Experimental Data.---The paper contains (1) magnetization curves (Fig. 4) for two specimens of hematite; (2) hysteresis loops at fields from 9.5 to 1020 gausses, some obtained with a rotating field (Figs. 6, 7, 8, 9, 11), the others with an alternating field (Figs. 10, 11); (3) a graph representing components of magnetization parallel and perpendicular to the field (Fig. 12).Deduction, The normal magnetization curve of hematite consists of a sharp rise followed by a slow increase, which is proportional to the field strength. The hysteresis energy loss increases with an increase in the maximum field applied up to a certain field, and thereafter the area of the hysteresis loop remains constant. For the specimen on which most of the present measurements were made, the hysteresis loss is constant for field strengths above about 150 gausses.
Analysis of Functional Domain Organization in DNA Topoisomerase II from Humans and <i>Saccharomyces cerevisiae</i> (1996)

The functional domain structure of human DNA topoisomerase IIalpha and Saccharomyces cerevisiae DNA topoisomerase II was studied by investigating the abilities of insertion and deletion mutant enzymes to support mitotic growth and catalyze transitions in DNA topology in vitro. Alignment of the human topoisomerase IIalpha and S. cerevisiae topoisomerase II sequences defined 13 conserved regions separated by less conserved or differently spaced sequences. The spatial tolerance of the spacer regions was addressed by insertion of linkers. The importance of the conserved regions was assessed through deletion of individual domains. We found that the exact spacing between most of the conserved domains is noncritical, as insertions in the spacer regions were tolerated with no influence on complementation ability. All conserved domains, however, are essential for sustained mitotic growth of S. cerevisiae and for enzymatic activity in vitro. A series of topoisomerase II carboxy-terminal truncations were investigated with respect to the ability to support viability, cellular localization, and enzymatic properties. The analysis showed that the divergent carboxy-terminal region of human topoisomerase IIalpha is dispensable for catalytic activity but contains elements that specifically locate the protein to the nucleus.
Dynamic auto-encoders for semantic indexing (2010)

We present a new algorithm for topic modeling, text classification and retrieval, tailored to sequences of time-stamped documents. Based on the auto-encoder architecture, our nonlinear multi-layer model is trained stage-wise to produce increasingly more compact representations of bags-of-words at the document or paragraph level, thus performing a semantic analysis. It also incorporates simple temporal dynamics on the latent representations, to take advantage of the inherent structure of sequences of documents, and can simultaneously perform a supervised classification or regression on document labels. Learning this model is done by maximizing the joint likelihood of the model, and we use an approximate gradient-based MAP inference. We demonstrate that by minimizing a weighted cross-entropy loss between histograms of word occurrences and their reconstruction, we directly minimize the topic-model perplexity, and show that our topic model obtains lower perplexity than Latent Dirichlet Allocation on the NIPS and State of the Union datasets. We illustrate how the dynamical constraints help the learning while enabling to visualize the topic trajectory. Finally, we demonstrate state-of-the-art information retrieval and classification results on the Reuters collection, as well as an application to volatility forecasting from financial news. 1

Percutaneous Stent-Graft Repair of Anastomotic Pseudoaneurysms following Vascular Bypass Procedures: A Report of Two Cases (2013)

Anastomotic pseudoaneurysms are common entities following vascular bypass procedures and, if left untreated, serious complications such as thromboses, infection, and rupture can frequently occur. Therefore, attempts to employ various methods of repair have been utilized in treating anastomotic pseudoaneurysms to maximize operational success and future risk reduction. Herein, the authors report two cases of anastomotic pseudoaneurysms which were repaired percutaneously utilizing a combination of strategies such as careful preoperational image planning, multiple commercially available devices, and secondary embolization techniques.
Drying of gelcast ceramics (1991)

Plates (8.9 {times} 90.2 {times} 228.6 mm) of silicon nitride, sialon, and alumina made by gelcasting, a generic near-net-shape forming process, have been dried in a controlled humidity chamber. No constant-rate period was found in drying the gelcast plates. A linear shrinkage of 3--4% was observed, the shrinkage stopping after only about 20% of the total moisture had been lost. Dried parts, free of warpage and cracking, were obtained in reasonable times by controlling the humidity and temperature. 12 refs., 4 figs.

Comprehensive two‐dimensional liquid chromatography (NPLC×RPLC) with vacuum‐evaporation interface (2008)

A comprehensive two-dimensional liquid chromatographic system incorporating a vacuum-evaporation interface was developed. Normal-phase liquid chromatography with a CN microcolumn was used as the first dimension (1(st)-D), and reversed-phase liquid chromatography with a C(18) monolithic column was used as the second dimension (2(nd)-D). An electronically controlled dual-position, ten-port valve with two identical storage loops served as the interface and the analysis time in the 2(nd)-D was 1.5 min. The solvent in the loops of the interface was evaporated at 25 degrees C under vacuum conditions, leaving the analytes on the inner wall of the loops. The mobile phase of the 2(nd)-D dissolved the analytes in the loop and injected them onto the second column, allowing an on-line solvent exchange of the fractions from the 1(st)-D to the 2(nd)-D. The chromatographic resolution of analytes on the two dimensions was evaluated. Sample loss due to evaporation in the interface was investigated with standard samples having different boiling points. The usefulness of the comprehensive 2-DLC system was demonstrated in the analysis of a traditional Chinese medicine Radix salviae miltiorrhiza bage extract.
