FUEL INSTABILITY STUDIES: THE CHEMICAL VALIDATION OF ASTM METHOD D5304 (2001)

The current ASTM (D5304) procedure for determining storage stability involves rather drastic conditions, namely, 16 hours at 90°C and under 100 psig of oxygen. These mandated test conditions give rise to the question, “Does the reaction conditions induce chemical instability, or is it an accurate measure of the true instability process?” Several organo-sulfur functional groups are known to be present in petroleum derived fuels. Thiophenes, benzothiophenes, sulfides, disulfides, and trace amounts of thiols are the organo-sulfur compounds most prevalent. The reaction of organo-sulfur compounds under the ASTM reaction conditions have not been investigated. The purpose of the present research is to determine if the ASTM reaction conditions induce a reaction in an otherwise stable fuel matrix.
A supercritical fluid-based coating technology 1: Process considerations (2003)

A novel solvent-free particle coating process, based on the solvent properties of supercritical fluids (SCF) is described. It consists of dissolving one or more coating materials in supercritical CO(2) and then adjusting T/P conditions in the autoclave so that the coating material becomes insoluble in the CO(2). This insolubilization step causes a coating to deposit on the surface of suspended particles. This process has been applied to bovine serum albumin and sugar granules. Coating was effective, but different morphologies were obtained depending on the coating material used. A discontinuous coating has been made using trimyristin, since this material precipitates as micro-needles. Conversely, a smooth, regular coating has been obtained with a commercially available mixture of glycerides and glyceride esters of PEG (Gelucire 50/02) acting like a film-forming agent.
Quantifying the effects of online bullishness on international financial markets (2015)

Computational methods to gauge investor sentiment from commonly used online data sources that rely on machine learning classifiers and lexicons have shown considerable promise, but suffer from measurement and classification errors. In our work, we develop a simple, direct and unambiguous indicator of online investor sentiment, which is based on Twitter updates and Google search queries. We examine the predictive power of this new investor bullishness indicator for international stock markets. Our results indicate several striking regularities. First, changes in Twitter bullishness predict changes in Google bullishness, indicating that Twitter information precedes Google queries. Second, Twitter and Google bullishness are positively correlated to investor sentiment and lead established investor sentiment surveys. The former, in particular, is a more powerful predictor of changes in sentiment in the stock market than the latter. Third, we observe that high Twitter bullishness predicts increases in stock returns, with these then returning to their fundamental values. We believe that our results may support the investor sentiment hypothesis in behavioural finance.

Genomic and metabolic characterization of succinate dehydrogenase B deficient renal cell carcinoma. (2016)

e16102 Background: Succinate dehydrogenase B (SDHB)-deficient renal cell carcinoma (RCC) is a rare histologic subtype characterized by loss of SDHB expression, a key subunit of succinate dehydrogenase (SDH) in the tricarboxylic acid (TCA) cycle. Loss of SDH is also seen in gastrointestinal stromal tumors and hereditary paraganglioma-pheochromocytoma syndrome. SDHB-deficient RCC is typically indolent; however, it can develop into highly aggressive disease, and the pathogenesis and pathophysiology remain poorly understood. Methods: From 2014 – 2015, 3 patients with highly aggressive hereditary SDHB-deficient RCC were identified. The genomics were examined by whole genome and targeted exome sequencing. SDHB-/- and SDHB+/-cell lines were generated from the tumor and tumor-associated stroma of 1 patient. Results: Patients had high 13F-deoxyglucose (FDG) uptake on PET scan (Max SUV up to 48) and hyperlactatemia (up to 13 mM/L) that increased with tumor burden. Increased glutamine uptake was also seen by 13F-glutamine PET. Histologies were diverse, but all showed loss of SDHB expression by IHC and loss of heterozygosity of SDHB with a germline mutation in the remaining allele. In one patient, no other genomic alterations were identified by whole genome sequencing, suggesting that loss of SDHB may be sufficient for tumorigenesis. SDHB-/- cells had disturbed mitochondrial architecture with less cristae and an enlarged matrix by electron microscopy. Metabolic assessment of SDHB-/- cells showed increased glucose consumption and lactate production, and defective oxidative respiration. Measurement of intracellular metabolites by mass spectroscopy showed a > 60 fold increase in succinate, which could be reduced by glutamine deprivation. The SDHB-/- cell line was also more sensitive to glucose and glutamine deprivation compared to SDHB+/+cell lines. Conclusions: Loss of SDHB alone appears to be sufficient for tumorigenesis and induces dramatic metabolic shifts, as an extreme example of the Warburg Effect. Agents directed towards altering metabolism, such as mTOR targeted and glutaminase inhibitors, should be further explored.
Thin Co/Ni-based bottom pinned spin-transfer torque magnetic random access memory stacks with high annealing tolerance (2016)

Spin-transfer torque magnetic random access memory (STT-MRAM) is considered as a replacement for next generation embedded and stand-alone memory applications. One of the main challenges in the STT-MRAM stack development is the compatibility of the stack with CMOS process flows in which thermal budgets up to 400 °C are applied. In this letter, we report on a perpendicularly magnetized MgO-based tunnel junction (p-MTJ) on a thin Co/Ni perpendicular synthetic antiferromagnetic layer with high annealing tolerance. Tunnel magneto resistance (TMR) loss after annealing occurs when the reference layer loses its perpendicular magnetic anisotropy due to reduction of the CoFeB/MgO interfacial anisotropy. A stable Co/Ni based p-MTJ stack with TMR values of 130% at resistance-area products of 9 Ω μm2 after 400 °C anneal is achieved via moment control of the Co/Ta/CoFeB reference layer. Thinning of the CoFeB polarizing layer down to 0.8 nm is the key enabler to achieve 400 °C compatibility with limited TMR loss. Thinning the Co below 0.6 nm leads to a loss of the antiferromagnetic interlayer exchange coupling strength through Ru. Insight into the thickness and moment engineering of the reference layer is displayed to obtain the best magnetic properties and high thermal stability for thin Co/Ni SAF-based STT-MRAM stacks.
[The methylation analysis of EMP3 and PCDH-gamma-A11 gene in human glioma]. (2010)

The promoter methylation of EMP3 and PCDH-gamma-A11 genes may lead to the down-regulation of their mRNA levels in glioma. The promoter methylation and mRNA expressions of EMP3 and PCDH-gamma-A11 are closely related with the malignant development of glioma. The promoter methylation of the two genes may provide clues to evaluation of glioma malignancy as well as its prognosis. It also gives us an insight for future glioma medical therapy with a demethylating agent.
DEPMOSFET Active Pixel Sensor Prototypes for the XEUS Wide Field Imager (2005)

Active pixel sensors (APS) based on the DEPMOSFET (depleted p-channel MOSFET) recently produced at the MPI semiconductor laboratory are a promising new type of sensor to cope with the advanced requirements of the XEUS wide field imager. DEPMOSFET APS combine high energy resolution and random accessibility of pixels providing for highly flexible readout modes with fast readout speed. In the first prototype production, several design variants of 64 /spl times/ 64 pixel DEPMOSFET matrices with a pixel size of 75 /spl times/ 75 /spl mu/m/sup 2/ have been realized. A data acquisition system (DAQ) for evaluation of sensor prototypes has been developed, which allows for a performance characterization of the different designs. For operation, DEPMOSFET device, front-end IC and control ICs are integrated onto a readout hybrid. Device readout is done row by row, addressing and resetting one single matrix row at a time and processing the signals with a 64 channel parallel CMOS amplifier / multiplexer IC of the CAMEX type applying 8-fold correlated double sampling. Addressing and resetting of the matrix rows is done by two control ICs of the SWITCHER type fabricated in a high voltage CMOS technology. A number of readout hybrids has been built, the characterization of the different devices in terms of noise, spectral resolution and charge collection efficiency is in progress. The most promising DEPMOSFET matrix design variants, the DAQ system and measured key performance parameters of the devices are presented.
Melusin gene therapy: a novel approach to fight familial dilated cardiomyopathy (2013)

We have previously demonstrated that melusin, a muscle specific chaperone protein, is required for cardiac compensatory response to stress conditions (Brancaccio et al 2003) and its overexpression effectively counteracts cardiac dilation and heart failure induced by aortic stenosis (De Acetis et al 2005). Chaperones are cytoprotective proteins that recognize a broad panel of proteins partially damaged by stress conditions or genetic mutations allowing them to retain correct function. Using and in vivo gene therapy approach with cardiotropic adeno associated virus 9 vector we show that overexpression of melusin effectively counteract dilated cardiomyopathy in a mouse model mimicking human Emery Dreyfus familial cardiomyopathy caused by LaminA H222P mutation. These mice develop spontaneous dilated cardiomyopathy with age and males die within 8-10 month of age due conduction defect and sudden death. One month old homozygous mutant mice were injected with AAV9-Melusin or with AAV9-LacZ as control (I.V. injection of 1012 viral particles/mouse) and their cardiac function was monitored by echocardiography for the following 8 months. While mice injected with control virus progressively developed left ventricle dilation and reduced contractility (FS%), mice injected with AAV9-Melusin retained physiological level of contractility and were protected toward LV dilation. More interestingly, 8 month after the treatment, 40% of control mutant mice died as described by the literature, while Melusin-treated mice were 100% alive. Biochemical analysis indicated that melusin binds LaminA in cardiomyocyte, suggesting that chaperone function is crucial for the protective effect. These data indicate that melusin gene therapy has a strong potential to treat familial cardiomyopathy.
Mechanical Behavior of Flat Braided Composites (2021)

In the search for industrial applications of composites, 3D reinforcements are necessary. It has been demonstrated that braided fabric could provide the 3D configuration for the reinforcement of composites. Orientation, crimp and the continuity of fibers are important factors that can affect the mechanical performances and fracture behavior of a 3D fiber reinforced composite. Furthermore, in braided composite it is found that the direction of fibers is not constant throughout the structure. Therefore, it is important to have an analytical model containing fibers with various orientations. In most of the finite element models that have been developed recently (1,2) for the analysis and design of braided fiber reinforced composites, only beam and shell elements were employed. These models are useful but did not give detailed information on local failure or defect. In this study, a parametrical model constituted of 3D solid elements was used to investigate the mechanical properties a bar made of flat braided composite. Tensile tests were conducted on samples having fiber direction angle of 25.1° and 62.6° in order to verify the analytical prediction.
Aggregation of bubbles by thermocapillary flow (2000)

Thermocapillary flow near adjacent bubbles on heated surfaces explains bubble aggregation on a hot surface. The bubbles pump fluid away from the heated surface; this action draws liquid near the wall laterally toward the bubble. Bubbles mutually entrain each other in this flow pattern and aggregate. Experimentally, it has been found that pairs of bubbles placed near the hot surface aggregated; if the gradient was reversed, they separated. Theory based on thermocapillary flow provides the correct scaling and reasonable agreement with experimental data for approximately equal-sized bubbles.
Differentiation of Saccharomyces cerevisiae at Slow Growth Rates in Glucose-limited Chemostat Culture (1982)

Saccharomyces cerevisiae was grown in a glucose-limited chemostat at dilution rates equivalent to mass doubling times of 2 to 16 h. Phase contrast microscopy revealed that cultures with mass doubling times greater than 4·5 h contained two sub-populations of cells, phase-dark and phase-light. The latter were shown to be predominantly unbudded daughter cells, which were not proliferating, and had properties similar to those of stationary phase cells in batch culture. Phase-dark cells were equivalent to cells growing exponentially in batch culture. The results suggest that the formation of phase-light cells represents cell cycle specific differentiation into stationary phase. The consequences of this phenomenon for the interpretation of results obtained with S. cerevisiae in the chemostat are discussed.

Effects of Ligands on the Mobility of an Active-Site Loop in Tyrosine Hydroxylase as Monitored by Fluorescence Anisotropy (2006)

Fluorescence anisotropy has been used to monitor the effect of ligands on a mobile loop over the active site of tyrosine hydroxylase. Phe184 in the center of the loop was mutated to tryptophan, and the three native tryptophan residues were mutated to phenylalanine to form an enzyme with a single tryptophan residue in the mobile loop. The addition of 6-methyl-5-deazatetrahydropterin to the enzyme resulted in a significant increase in the fluorescence anisotropy. The addition of phenylalanine did not result in a significant change in the anisotropy in the presence or absence of the deazapterin. The K(d) value for the deazapterin was unaffected by the presence of phenylalanine. Qualitatively similar results were obtained with apoenzyme, except that the addition of phenylalanine led to a slight decrease in anisotropy. Frequency-domain lifetime measurements showed that the distribution of lifetimes was unaffected by both the amino acid and deazapterin. Frequency-domain anisotropy analyses were consistent with a decrease in the motion of the sole tryptophan in the presence of the deazapterin. This could be modeled as a decrease in the cone angle for the indole ring of about 12 degrees . The data are consistent with a model in which binding of a tetrahydropterin results in a change in the conformation of the surface loop required for proper formation of the amino acid binding site.
Function of Nanocatalyst in Chemistry of Organic Compounds Revolution: An Overview (2013)

Heterocyclic motif is an important scaffold which has both industrial and pharmaceutical applications. These motifs can be prepared using wide variety of reaction conditions such as the use of expensive catalyst, toxic solvent, harsh reaction condition like the use of base, high temperature, and multistep reaction. Although various methods are involved, the chemistry arena is now shifted towards the greener way of synthesis. Nanocatalyst constitutes an important role in the green synthesis. This is because the activity of the catalyst resides in the exposed portion of the particles. By decreasing the size of the catalyst, advantages such as more surface area would be exposed to the reactant, only negligible amount would be required to give the significant result and selectivity could be achieved, thereby, eliminating the undesired products. The current review enlists the various types of nanocatalyst involved in the heterocyclic ring formation and also some other important functionalization over the ring.
Highly Active Mixed-Phase Cu–Al Catalyst for Methanol Steam Reforming (2017)

In the present study, mixed-phase Cu–Al catalysts have been synthesized by an autocombustion method using glycine as fuel. By adjusting the ratio of glycine, the self-reductive Cu–Al mixed oxides were prepared and demonstrated higher activity than a commercial Cu-based catalyst in the catalytic performance test, where the WHSV was 12/h and the steam/methanol ratio was 1.1. The relationships between the physicochemical properties of the prepared Cu–Al catalysts and the catalytic performance have thoroughly been investigated by various characterization methods, such as BET, in-situ XRD and TEM.
Pre-Emphasis and Equalization Parameter Optimization with Fast, Worst-Case/Multibillion-Bit Verification (2007)

Designing a robust serial channel to meet the Bit Error Rate (BER) requirements of today’s serial protocols is a challenge for most system designers. It is imperative that designers have techniques that will allow them to accurately predict the behavior of their designs to meet these BER requirements as well as techniques to improve quality when designs fail. This paper covers a novel technique for quickly determining optimum settings for pre-emphasis and equalization while using advanced simulation techniques to validate the behavior over billions of bits and with the worst case stimulus. Results from the analysis are compared to conventional simulation techniques and hardware measurements of a serial channel, including measured versus simulated Bit Error Rate (BER) and eye aperture.
