Bioaccumulation From Mineral Oil-Wet and Synthetic Liquid-Wet Cuttings in an Estuarine Fish, <i>Fundulus grandis</i> (1991)

ABSTRACT The long-term effects of discharged oily drill cuttings on native fish populations are of major concern. This study investigates the uptake of oil and synthetic liquid by the mud minnow, Fundulus grandis. when exposed to three different concentrations of low-aromatic mineral oil-wet and synthetic liquid-wet cuttings in flow-through bioassay chambers. Fish were introduced into the flow-through bioassay system and cultured for 30 days. Water, cuttings, and fish were sampled routinely for analysis. Fish samples were dissected; gut and tissue samples were analyzed separately. Flow-through water was analyzed by extracting the water sampling tube absorbent. The cutting samples were analyzed by Soxhlet extraction. Fish tissue and gut samples were digested in sodium hydroxide and extracted with ether. The extracted organics in all the samples were analyzed by gas chromatograph!mass spectrometry. Gas chromatograph!mass spectrometry identified uptake of the mineral oil in fish tissue and gut samples for all cuttings treated with mineral oil-based mud (MOBM). No uptake was measured in any of the tissue samples for all cuttings treated with synthetic liquid-based mud (SBM). An accumulation of synthetic liquid was only detected in one sample of fish gut from the lowest concentration of SBM. The contrast in uptake between the mineral oil and the synthetic liquid is perhaps due to the greater molecular size of the synthetic liquid over that of the mineral oil. It is hypothesized that the greater molecular size of the synthetic liquid restricts uptake by gill and digestive structures. During the study, there was little migration of either base fluid from the cuttings. Hydrocarbon amounts in the water samples generally decreased during the 30-day test period. All collected organics were liberated as negligibly soluble microdroplets. Tests indicated no selective solubility of released microdroplets and little if any biodegradation for both SBM and MOBM.
[The nutritive value of wheat germ floc]. (1990)

The experimental investigation of the food value of wheat germ floc included the study of their chemical composition, biological value, and assimilability of the protein. Basing on the results obtained the authors have made a conclusion on the high food value of wheat germ floc and on their promising use as enriching additives to varying foodstuffs.
System-level integrated server architectures for scale-out datacenters (2011)

A System-on-Chip (SoC) integrates multiple discrete components into a single chip, for example by placing CPU cores, network interfaces and I/O controllers on the same die. While SoCs have dominated high-end embedded products for over a decade, system-level integration is a relatively new trend in servers, and is driven by the opportunity to lower cost (by reducing the number of discrete parts) and power (by reducing the pin crossings from the cores to the I/O). Today, the mounting cost pressures in scale-out dat-acenters demand technologies that can decrease the Total Cost of Ownership (TCO). At the same time, the diminshing return of dedicating the increasing number of available transistors to more cores and caches is creating a stronger case for SoC-based servers.
Pd/C-Catalyzed Deoxygenation of Phenol Derivatives Using Mg Metal and MeOH in the Presence of NH<sub>4</sub>OAc (2006)

A Pd/C-catalyzed deoxygenation method of phenolic hydroxyl groups via aryl triflates or mesylates using Mg metal in MeOH at room temperature was developed. The addition of NH4OAc dramatically affects the reactivity and reaction rate. This method is particularly attractive to provide an environmentally benign and widely applicable removal method of phenolic alcohols under quite mild reaction conditions.
Molecular Interaction between Limb Deformity Proteins (Formins) and Src Family Kinases (1996)

Ld proteins (formins) are encoded by the limb deformity (ld) gene and define a family of related gene products regulating establishment of embryonic polarity. In this study we establish that chicken and murine Ld proteins interact directly with Src family kinases (c-Src and c-Fyn). Specific binding is mediated by the proline-rich domain present in Ld proteins and the ligand binding surface of the Src SH3 domain. Co-immunoprecipitation of Ld and c-Src proteins from transfected cells shows that these proteins associate in vivo. Immunolocalization and biochemical fractionation of fibroblasts confirms the predominant nuclear localization of Ld proteins, but unexpectedly identifies a population of Ld proteins associated to cellular membranes. This population of Ld proteins co-localizes with membrane-associated c-Src proteins at both plasma and perinuclear membranes. These studies indicate that the morphoregulatory Ld proteins interact with signal transduction cascades by association to membrane-bound Src family kinases.
Characterization of an Intermediate in the Ammonia-Forming Reaction of Fe(DMeOPrPE)<sub>2</sub>N<sub>2</sub> with Acid (DMeOPrPE = 1,2-[bis(dimethoxypropyl)phosphino]ethane) (2013)

The reactivity of Fe(DMeOPrPE)2N2 with water and acid was explored. (DMeOPrPE is the bidentate phosphine 1,2-[bis(dimethoxypropyl)phosphino]ethane.) The complex reacts with acid to form trans-[Fe(DMeOPrPE)2(N2)H](+) and small amounts of ammonia and hydrazine. When reacted with H2O, cis-Fe(DMeOPrPE)2(H)2 is formed. To increase the yields of ammonia and hydrazine, we investigated the effect of anion, solvent, and acid addition rate on the yields of ammonia. Of these parameters, only the properties of the anion (i.e., of the acid) had a significant impact on the yields of ammonia. The highest yields of NH3 occurred with the largest/least-coordinating anion (triflate). A short-lived purple intermediate (τ1/2 < 5 s at 23 °C) was observed in the reaction of Fe(DMeOPrPE)2N2 with triflic acid. Because the structure of this purple species could potentially provide valuable insights into the mechanism of ammonia formation, a method was developed for independently synthesizing and stabilizing the complex. Spectroscopic characterization of the purple species identified it as the paramagnetic [((DMeOPrPE)2Fe)2(μ-N2)](2+) complex (1). This purple dimer (1) exists in equilibrium with yellow, monomeric, paramagnetic [Fe(DMeOPrPE)2N2](+) (2). The role of 1 in the formation of hydrazine and ammonia was probed by reacting 1 with acid.

Document Clustering Using Reference Titles (2010)

Titles have been regarded as having effective clustering features, but they sometimes fail to represent the topic of a document and result in poorly generated document clusters. This study aims to improve the performance of document clustering with titles by suggesting titles in the citation bibliography as a clustering feature. Titles of original literature, titles in the citation bibliography, and an aggregation of both titles were adapted to measure the performance of clustering. Each feature was combined with three hierarchical clustering methods, within group average linkage, complete linkage, and Ward's method in the clustering experiment. The best practice case of this experiment was clustering document with features from both titles by within-groups average method.

Walking Skill Can Be Assessed in Older Adults: Validity of the Figure-of-8 Walk Test (2009)

The F8W is a valid measure of walking skill among older adults with mobility disability and may provide information complementary to gait speed.
Notch filter tuning for resonant frequency reduction in dual inertia systems (2003)

This paper presents a technique to measure the resonant frequency of a dual inertia spring system using an FFT. The resonant frequency measurement and anti-resonant frequency calculation are utilized to tune an infinite impulse response notch filter to reduce the torsional oscillations in both the motor and load velocities. The simplicity and easy tuning of the filter makes it practical to implement in a DSP. The baseband performance of a resonant system would greatly improve.

Biomedical evaluation of nanomedicines (2014)

Abstract Nanotechnology is a newly fashionable field but in the world of drug development it is certainly not new. Nanotechnology has a vital role to play in realizing cost-effective diagnostic, therapeutic and prevent tools. The applications of nanotechnology for treatment, diagnosis, monitoring and control of biological systems have recently been referred to as nanomedicine. The nanocarriers have been made of safe materials, including synthetic biodegradable polymers, lipids and polysaccharides. Nanomedicines can be developed either as drug delivery systems or biologically active drug products. Application of nanotechnology is just started in traditional Chinese medicines. The change in the physicochemical and structural properties of engineered nanosized materials with a decrease in size could be responsible for a number of material interactions that could lead to toxicological effects. At present, scientists must accept that it is still very early in the toxicological evaluation for nanomaterials and nanomedicines, and few data on the safety and toxicity. The safety evaluation of nanomedicines includes workforce exposure limits in manufacturing process, environment impact with general impact and to patients after administration and safety for human use, such as depends on route of administration, dose and dosing frequency, as well as safety in drug delivery relates to toxicity of drug payload. The biomedical evaluation of nanomedicines includes

DNA-like class R inhibitory oligonucleotides (INH-ODNs) preferentially block autoantigen-induced B-cell and dendritic cell activation in vitro and autoantibody production in lupus-prone MRL-Fas lpr/lpr mice in vivo (2009)

Abstract Introduction B cells have many different roles in systemic lupus erythematosus (SLE), ranging from autoantigen recognition and processing to effector functions (for example, autoantibody and cytokine secretion). Recent studies have shown that intracellular nucleic acid-sensing receptors, Toll-like receptor (TLR) 7 and TLR9, play an important role in the pathogenesis of SLE. Dual engagement of rheumatoid factor-specific AM14 B cells through the B-cell receptor (BCR) and TLR7/9 results in marked proliferation of autoimmune B cells. Thus, strategies to preferentially block innate activation through TLRs in autoimmune B cells may be preferred over non-selective B-cell depletion. Methods We have developed a new generation of DNA-like compounds named class R inhibitory oligonucleotides (INH-ODNs). We tested their effectiveness in autoimmune B cells and interferon-alpha-producing dendritic cells in vitro and in lupus-prone MRL-Fas lpr / lpr mice in vivo . Results Class R INH-ODNs have 10- to 30-fold higher inhibitory potency when autoreactive B cells are synergistically activated through the BCR and associated TLR7 or 9 than when stimulation occurs via non-BCR-engaged TLR7/9. Inhibition of TLR9 requires the presence of both CCT and GGG triplets in an INH-ODN, whereas the inhibition of the TLR7 pathway appears to be sequence-independent but dependent on the phosphorothioate backbone. This difference was also observed in the MRL-Fas lpr / lpr mice in vivo , where the prototypic class R INH-ODN was more effective in curtailing abnormal autoantibody secretion and prolonging survival. Conclusions The increased potency of class R INH-ODNs for autoreactive B cells and dendritic cells may be beneficial for lupus patients by providing pathway-specific inhibition yet allowing them to generate protective immune response when needed.
Upregulation of Interleukin 6 and Granulocyte Colony-Stimulating Factor Receptors by Transcription Factor CCAAT Enhancer Binding Protein α (C/EBPα) Is Critical for Granulopoiesis (1998)

Cytokines stimulate granulopoiesis through signaling via receptors whose expression is controlled by lineage-specific transcription factors. Previously, we demonstrated that granulocyte colony-stimulating factor (G-CSF) receptor mRNA was undetectable and granulocyte maturation blocked in CCAAT enhancer binding protein alpha (C/EBPalpha)-deficient mice. This phenotype is distinct from that of G-CSF receptor-/- mice, suggesting that other genes are likely to be adversely affected by loss of C/EBPalpha. Here we demonstrate loss of interleukin 6 (IL-6) receptor and IL-6-responsive colony-forming units (CFU-IL6) in C/EBPalpha-/- mice. The observed failure of granulopoiesis could be rescued by the addition of soluble IL-6 receptor and IL-6 or by retroviral transduction of G-CSF receptors, demonstrating that loss of both of these receptors contributes to the absolute block in granulocyte maturation observed in C/EBPalpha-deficient hematopoietic cells. The results of these and other studies suggest that additional C/EBPalpha target genes, possibly other cytokine receptors, are also important for the block in granulocyte differentiation observed in vivo in C/EBPalpha-deficient mice.
Universal criterion for metallic glass formation (1997)

It is proposed that a simple criterion for topological instability applied to local atomic structure can explain a wide variety of phase transition phenomena involving metallic elements and alloys. These include melting, alloy formation, glass transition, solid state amorphization, and glass formation by rapid quenching. It can also provide a microscopic basis to explain the local structure of metallic glasses and their relaxation phenomena. Such simple theories are complementary to precise numerical computational theories in facilitating full understanding of the phenomena.
Dual scalable 500MS/s, 5b time-Interleaved SAR ADCs for UWB applications (2006)

A dual 500MS/s, 5b ADC chip is implemented in a 0.18 mum CMOS process. The two ADCs have synchronized sampling for use in an I/Q UWB receiver. Each ADC has a 6-way time-interleaved successive approximation register topology and uses full custom logic, self-timed bit-cycling, and duty cycling of the comparator preamplifiers to enable 500MS/s operation with 7.8mW power consumption
Ultra-fast 3G videotelephony session setup (2005)

The establishment of a typical 3G videotelephony (video calls) session is a process that lasts typically around 5 to 8 seconds between today's deployed 3G video-call enabled terminals. This delay is exclusive of call signalling, and is due to the need to complete several protocol procedures as prescribed by the ITU-T H.324 standard and its annex C, including mobile level detection and H.245 messaging to open logical channels and define multiplexing modes. This paper presents AnswerFast Plus (AF+), a technique that significantly accelerates the 3G videotelephony session setup to make it almost as fast as voice calls (1 second or less). AF+ establishes a video telephony session in a 1/2 round-trip duration of information transmission on the bearer channel, which is the minimum that can be achieved, while maintaining the flexibility of exchanging terminal preferences. AF+ offers major benefits not only from a user experience point of view, but also in terms of minimising infrastructure overheads, and reducing subscribers billing concerns. Another important advantage of AF+ is its interworking with deployed handsets. Because it is a 3G circuit-switched bearer based technology, and because AF+ information appears as noise to terminals that do not support it has an unmatched interworking record with existing deployed terminals. Extensive experiments on live 3G networks in a number of countries have been conducted and confirm our claims.
Hysteresis relaxation in (Pb,La)(Zr,Ti)O3 thin film capacitors with (La,Sr)CoO3 electrodes (1996)

We report on the thermally activated hysteresis relaxation effects in (La,Sr)CoO3/ (Pb,La)(Zr,Ti)O3/(La,Sr)CoO3 thin film ferroelectric capacitors. Films cooled in oxygen deficient ambients exhibit a marked voltage offset in the hysteresis loops. Upon the application of a dc bias voltage or unidirectional pulses of the same polarity as the offset, the loops become more symmetric. Subsequently, holding the capacitors in the original preferred polarization state leads to a relaxation of the hysteresis loop towards its original voltage offset condition. The relaxation process is described by a stretched exponential and is thermally activated.
Solid Oxide Fuel Cell System Development in VTT (2006)

The Finnish solid oxide fuel cell (SOFC) project (FINSOFC) was initiated in 2002 as a five-year project. It forms the core of the publicly funded SOFC research in Finland. The purpose of the project is to support the industry in its development of SOFC systems and components and other possible SOFC-based business to be created in the future. The project is coordinated by the VTT Technical Research Centre of Finland in cooperation with universities and industrial enterprises. The project is executed in close cooperation with several European partners both bilaterally and within Real-SOFC. The focus is to construct and run a natural gas-fueled 5kWe SOFC power plant demonstration connected to heat and electricity grids. The power plant demonstration contains a stack and all BOP components from fuel processing to power conditioning and grid connections. The aim is also to thoroughly understand the behavior of the system. The subprojects needed to do this are (i) fuel processing, (ii) testing of fuel cells and stacks, (iii) construction of a 5kWe power station demonstration, and (iv) system modeling.
Augmented Interface for Children Chinese Learning (2007)

The learning of Chinese is an abstract learning mode for kindergarten children; the pronunciation and writing of Chinese are different learning modes. This study tries to create a more efficient and interesting learning environment through AR. The paper describes the exertion of augmented reality (AR) to construct a learning system, where rich and effective interactions in learning were considered. The prototype of this AR learning system enables school children to have a better understanding in the pronunciation and memorization of Chinese. This clearly enhances the learning motives and interest of school children. In conclusion, the study shows a interesting way to promote Chinese phonetic alphabet learning via AR environment. The projector reveals AR does make the interaction and interface friendlier where children become more immersive in the scenario of learning.
Anxious depression. (1998)

Depression and anxiety often coexist. When they co-occur, both anxiety and depression appear to be more severe. Increased morbidity, poorer acute and long-term outcome, increased suicide risk, and increased treatment resistance are associated with comorbid anxiety and depression. The term anxious depression has taken on newer meaning with the changes in the diagnostic system that allow for concurrent diagnosis of anxiety disorders and major depression. Attention to the subtype of both anxiety and depression could have significant effects on treatment choice by the clinician. The authors review some historical aspects of anxious depression and also highlight some of the advances in differential diagnosis and treatment of coexisting depression and anxiety.
Presence of Functional Luteinizing Hormone/Chorionic Gonadotropin (hCG) Receptors in Human Breast Cell Lines: Implications Supporting the Premise that hCG Protects Women against Breast Cancer (1997)

We investigated MCF-7 and MDA-MB-231 human breast cancer cell lines and immortalized mammary epithelial HBL-100 cells for the presence of functional LH/hCG receptors. The results revealed that all three breast cell lines contain LH/hCG receptor mRNA transcripts and receptor proteins that can bind 125I-hCG. The MCF-7 cells, however, contain higher levels than the others. Culturing MCF-7 cells with highly purified hCG resulted in a dose- and time-dependent significant decrease in steady-state estradiol receptor mRNA and protein levels as compared to controls, with the maximal decrease occurring after 4 h of culture with 10 ng/ml hCG. The studies on cell growth demonstrated that hCG treatment in the presence of minimal or no fetal bovine serum had a time-dependent significant inhibitory effect on MCF-7 and HBL-100, but not on MDA-MB-231 cells. In summary, our results demonstrate that human breast cell lines contain functional LH/hCG receptors. The hCG effects in MCF-7 cells are consistent with a premise that hCG protects women against breast cancer.
