Measurement of asphaltene agglomeration from cold lake bitumen diluted with n-alkanes (1993)

A laser particle analyzer was used to study the formation of asphaltene agglomerates from Cold Lake bitumen due to the introduction of paraffinic diluents. The growth of the particles over time was investigated, and it was found that asphaltene particle growth is essentially an instantaneous process; that is, the final agglomerate size is reached within 5 seconds. The type of diluent used to precipitate the asphaltenes was determined to have a major effect on the size distribution of asphaltene agglomerates. The average particle size of asphaltene agglomerates ranged from 169 ptn for n-hexadecane to 299m for n-pentane. A relationship is shown to exist between the average particle size of asphaltene agglomerates and the carbon number of the diluent used. On a étudié à l'aide d'un analyseur laser de particules la formation d'agglomérats d'asphalténe de bitumes de Cold Lake due à I'introduction de diluants paraffiniques. On a étudié la croissance des particules dans le temps et on a trouvé que la croissance des particules d'asphalténe est essentiellement un processus instantané, à savoir que les agglomérats atteignent la taille définitive en 5 secondes. On a trouvé également que le type de diluant servant à précipiter les asphalténes a un effet significatif sur la distribution de taille des agglomérats d'asphalténe. La taille moyenne des particules des agglomérats d'asphalténe varie de 169 m pour le n-hexadécane 2 299 m pour le n-pentane. On montre qu'il existe une relation entre la taille moyenne des particules des agglomérats d'asphalténe et le nombre de carbones du diluant employé.
Partial reconfiguration on FPGAs in practice — Tools and applications (2012)

Abstract. Run-time reconfiguration of FPGAs has been around in aca-demia for more than two decades but it is still applied very seldom in industrial applications. This has two main reasons: a lack of killer applica-tions that substantially benefit from run-time reconfiguration and design tools that permit to quickly implement corresponding reconfigurable sys-tems. This tutorial gives a survey on state-of-the-art trends on reconfig-urable architectures and devices, application specific requirements, and design techniques and tools that are essential for implementing partial run-time reconfiguration on FPGAs. This is followed by a demonstra-tion of the floorplanning and constraint generation tool GoAhead. Fur-thermore, the tutorial will reveal several applications that benefit from partial reconfiguration, including network data processing, digital signal processing, cognitive radio, and systems on a reconfigurable chip. For these applications, the individual challenges and implementation issues are presented together with the achieved results. This tutorial demon-strates that partial FPGA reconfiguration is beneficial and applicable in industrial systems. 1
Detection of <i>Bacillus anthracis</i> DNA by LightCycler PCR (2002)

Anthrax is a zoonotic disease that is also well recognized as a potential agent of bioterrorism. Routine culture and biochemical testing methods are useful for the identification of Bacillus anthracis, but a definitive identification may take 24 to 48 h or longer and may require that specimens be referred to another laboratory. Virulent isolates of B. anthracis contain two plasmids (pX01 and pX02) with unique targets that allow the rapid and specific identification of B. anthracis by PCR. We developed a rapid-cycle real-time PCR detection assay for B. anthracis that utilizes the LightCycler instrument (LightCycler Bacillus anthracis kit; Roche Applied Science, Indianapolis, Ind.). PCR primers and probes were designed to identify gene sequences specific for both the protective antigen (plasmid pX01) and the encapsulation B protein (plasmid pX02). The assays (amplification and probe confirmation) can be completed in less than 1 h. The gene encoding the protective antigen (pagA) was detected in 29 of 29 virulent B. anthracis strains, and the gene encoding the capsular protein B (capB) was detected in 28 of 29 of the same strains. Three avirulent strains containing only pX01 or pX02, and therefore only pagA or pagB genes, could be detected and differentiated from virulent strains. The assays were specific for B. anthracis: the results were negative for 57 bacterial strains representing a broad range of organisms, including Bacillus species other than anthracis (n = 31) and other non-Bacillus species (n = 26). The analytical sensitivity demonstrated with target DNA cloned into control plasmids was 1 copy per microl of sample. The LightCycler Bacillus anthracis assay appears to be a suitable method for rapid identification of cultured isolates of B. anthracis. Additional clinical studies are required to determine the usefulness of this test for the rapid identification of B. anthracis directly from human specimens.
Polymorphism and Thermodynamic Stability of Zn <sub>7</sub> Sb <sub>2</sub> O <sub>12</sub> (2005)

The composition Zn 2.33 Sb 0.67 O 4 (or Zn 7 Sb 2 O 12 ) exists in two polymorphic forms. The thermodynamically stable, low‐temperature orthorhombic β form transforms to the high‐temperature cubic α‐polymorph with a spinel structure at 1225°±25°C. The transformation is fully reversible but slower in the α→β direction and therefore, it is easy to preserve the high‐temperature α‐polymorph to lower temperatures where it is kinetically stable but thermodynamically metastable. It is also possible to synthesize the α‐polymorph directly at low temperatures, e.g., 900°C. This synthesis, of a phase that is thermodynamically stable only at high temperatures, but which has sufficient kinetic stability to exist metastably at low temperatures, represents an example of Ostwald's law of successive reactions in which the first phase to crystallize from a reaction mixture is not necessarily the equilibrium phase of lowest free energy. The crystal structure of the α‐polymorph has been confirmed by Rietveld refinement of X‐ray powder diffraction data to be an inverse spinel, (Zn)[Sb 2/3 Zn 4/3 ]O 4 , in which octahedral sites contain a disordered, random mixture of Zn and Sb and tetrahedral sites are fully occupied by Zn.
Exploiting a GSM Network for Precise Payload Delivery (2009)

This paper introduces the novel concept of using a GSM network for command of and communications with multiple aerial delivery systems. The research prototype of such a system, Snowflake-N, allows communicating with other network clients via a commercial Blackberry Curve 8310 handheld over a Bluetooth connection. A new architecture allows reassigning targets and sending other relevant commands (via web interface, by voice, data, or text messages) to an onboard autopilot, which is within a network reach, from any place in the world. Similarly, a current position of the descending system and target assignment can be viewed from any computer connected to the Internet worldwide using a standard Google Earth viewer. The networking capability also allows uplinking the latest weather data measured by a portable target weather station, being a part of a network as well, and therefore drastically improving an accuracy of a payload delivery. The paper extends the previous work by the authors and introduces the current state of the Snowflake-N development. It presents a C 2 concept for the aerial delivery systems, talks about communication protocols, presents the hardware set-up, components and results of recent drops. The paper ends with conclusions and recommendations for further development.

Anchorage-independent cell growth-inhibiting factor(s) from normal rat liver and ascites hepatoma (1986)

Acid/ethanol extracts of normal rat liver and rat ascites hepatoma cells (AH 130) were found to inhibit the epidermal growth factor (EGF)-dependent colony formation of Balb/c 3T3 cells. The extracts did not inhibit the growth of the 3T3 cells in monolayer culture. The inhibitory activities were heat- and acid-stable and were not inactivated by the treatment with pronase, RNase and DNase. Upon ultrafiltration, a considerable fraction of the inhibitory activities were found in the fraction corresponding to the molecular size ranging from 3.5 to 10 Kd, in which no appreciable TGF-beta activity was detected.
Thermal oxidation of tantalum silicide in O2 and H2O (1982)

Thermal oxidation of TaSi2 in dry oxygen and steam has been investigated. 0.3-μm-thick films of tantalum silicide were deposited by cosputtering on high resistivity 〈111〉 silicon and oxidized silicon wafers. After a crystallization anneal in argon, the films were oxidized in dry O2 or steam at 1000 and 1100 °C. In all cases oxidation was observed. For TaSi2 deposited on Si, only the growth of SiO2 was observed, indicating that the Si diffused through TaSi2 before oxidation, and TaSi2 remained intact. In the case where TaSi2 was deposited on SiO2, it was actively involved in the oxidation process, resulting in the formation of SiO2 and Ta2O5.
[Clinical evaluation of desmopressin (DDAVP) in diabetes insipidus: solution vs tablets]. (1992)

Efficacy and tolerability of perorally administered desmopressin were evaluated in 12 adult patients suffering from central diabetes insipidus. According to the results of the study desmopressin should be administered at a higher dosage than 300 micrograms/die to obtain the same antidiuretic effect as with the intranasal administration. No significant changes in body weight, arterial pressure and blood chemistry parameters have been detected over the whole administration period and only some slight side-effects occurred. Oral desmopressin may be considered as an effective alternative to traditional intranasal administration and it may significantly improve patients' compliance.
Power Loss-Oriented Evaluation of High Voltage IGBTs and Multilevel Converters in Transformerless Traction Applications (2005)

The low-frequency line transformer in todays ac rail vehicles suffers from poor efficiency and a substantial weight. Future traction drives may operate directly from the mains without this transformer. A feasible concept for a transformerless drive system consists of series connected medium voltage converters applying modern high-voltage insulated gate bipolar transistors (HV-IGBTs). In a first design step, the switching characteristics and losses of 6.5-kV IGBTs are compared to 3.3-kV and 4.5-kV IGBTs which are already commercially used in traction applications. Based on the considered HV-IGBTs, the properties of multilevel converters are analyzed and their applicability to the transformerless system is evaluated. The paper focusses on a loss analysis of the converters. Reliability aspects and harmonic spectra are briefly discussed. Taking these design aspects into account, the three-level neutral point clamped converter turns out to be a reasonable solution to realize line and motor converter modules in a transformerless traction system.
The dynamic metabolism of hyaluronan regulates the cytosolic concentration of UDP-GlcNAc (2014)

Hyaluronan, a macromolecular glycosaminoglycan, is normally synthesized by hyaluronan synthases at the plasma membrane using cytosolic UDP-GlcUA and UDP-GlcNAc substrates and extruding the elongating chain into the extracellular space. The cellular metabolism (synthesis and catabolism) of hyaluronan is dynamic. UDP-GlcNAc is also the substrate for O-GlcNAc transferase, which is central to the control of many cytosolic pathways. This Perspective outlines recent data for regulation of hyaluronan synthesis and catabolism that support a model that hyaluronan metabolism can be a rheostat for controlling an acceptable normal range of cytosolic UDP-GlcNAc concentrations in order to maintain normal cell functions.

NRG1 / ERBB3 signaling in melanocyte development and melanoma: inhibition of differentiation and promotion of proliferation (2009)

Neuregulin (NRG) signaling through the receptor tyrosine kinase, ERBB3, is required for embryonic development, and dysregulated signaling has been associated with cancer progression. Here, we show that NRG1/ERBB3 signaling inhibits melanocyte (MC) maturation and promotes undifferentiated, migratory and proliferative cellular characteristics. Embryonic analyses demonstrated that initial MC specification and distribution were not dependent on ERBB3 signaling. However NRG1/ERBB3 signaling was both necessary and sufficient to inhibit differentiation of later stages of MC development in culture. Analysis of tissue arrays of human melanoma samples suggests that ERBB3 signaling may also contribute to metastatic progression of melanoma as ERBB3 was phosphorylated in primary tumors compared with nevi or metastatic lesions. Neuregulin 1-treated MCs demonstrated increased proliferation and invasion and altered morphology concomitant with decreased levels of differentiation genes, increased levels of proliferation genes and altered levels of melanoma progression and metastases genes. ERBB3 activation in primary melanomas suggests that NRG1/ERBB3 signaling may contribute to the progression of melanoma from benign nevi to malignancies. We propose that targeting ERBB3 activation and downstream genes identified in this study may provide novel therapeutic interventions for malignant melanoma.
Process for the formation of biaxially oriented films of poly(<i>p</i>‐phenylene terephthalamide) from liquid crystalline solutions (1982)

Abstract A new process for making equal biaxially oriented films from liquid crystalline solutions of poly(p‐phenylene terephthalamide) (PPD‐T) is described. The process involves extruding solutions of PPD‐T/H 2 SO 4 through an annular die and over an oil‐coated mandrel into a coagulation bath. The films were studied using wide angle X‐ray diffraction (WAXS) and scanning electron microscopy (SEM). Tensile stress–strain properties were obtained on samples cut at various directions in the plane of the film. Biaxially oriented films which possess equal properties in the various directions in the plane of the film were produced. Moduli of 2.3 × 10 9 Pa and tensile strengths of 9.6 × 10 7 Pa were obtained in the plane of the film. Films with unequal biaxial orientation were also produced. These tend to have higher modulus/tensile strength in the direction of major orientation, the machine direction (up to 8.3 × 10 9 Pa/2.5 × 10 8 Pa), but become brittle in the transverse direction.
A New Fuse Architecture and a New Post-Share Redundancy Scheme for Yield Enhancement in 3-D-Stacked Memories (2014)

3-D-stacked memory using through-silicon-vias (TSVs) has emerged as a good alternative for overcoming the limitation of 2-D memory technology. Among many issues with 3-D-stacked memory, yield is one of the major challenges for mass production. This paper proposes a new fuse architecture and redundancy scheme to improve the yield of 3-D-stacked memories. The new fuse architecture is developed based on the fact that the unused redundancies in prebond repair cause the inefficiency. Therefore, the new fuse architecture provides a way to share redundancies in prebond and postbond repairs. There are two kinds of operation modes. One is an enable mode for collecting the used redundancy information. The other is a mask mode for obtaining faulty redundancy information using a short test algorithm. Using the new fuse architecture, a new redundancy scheme called the post-share scheme is developed to achieve optimal yield. The post-share scheme allocates the fixed number of spare rows and columns for each repair just like other schemes. However, only allocated redundancies are used in prebond repair, while both the redundancies allocated for postbond repair and unused redundancies in prebond repair can be used for postbond repair. Experimental results show that the post-share redundancy scheme significantly increases the final yield of 3-D-stacked memories and the increase of area overhead is small.

A low-voltage tunneling-based silicon microaccelerometer (1997)

This paper describes the design, fabrication, and testing of a low-voltage tunneling-based silicon microaccelerometer. The device has been successfully batch-fabricated by the boron etch-stop dissolved wafer process. A 4 h, 1100/spl deg/C oxygen, post-diffusion annealing process has been developed to eliminate the stress gradient in and warpage of thin (/spl ap/3 /spl mu/m) heavily-boron-doped silicon microstructures. Using a simple discrete readout circuit, the device with an active area of 400/spl times/400 /spl mu/m/sup 2/ provides a measured sensitivity of 1.66/spl times/10/sup 4/ ppm/g (133 mV/g), bandwidth of 2 kHz in air, and a full scale range of 30 g with a nonlinearity of 0.6%. The measured noise spectrum exhibits a typical 1/f behavior and drops from 1.75 mg//spl radic/Hz (at 50 Hz) to 0.25 mg//spl radic/Hz (at 2 kHz), corresponding to a minimum detectable acceleration of 22.8 mg. The variations of the offset output voltage and device sensitivity are /spl plusmn/40 mV (/spl ap/0.5%) and /spl plusmn/0.65 mV/g (/spl ap/0.49%) in continuous operation over thirty days. The temperature coefficient of offset (TCO) and temperature coefficient of sensitivity (TCS) are -600 ppm//spl deg/C and 1200 ppm//spl deg/C, respectively.
Gas immersion laser diffusion for efficient cell fabrication and grain boundary research (1983)

Antlerogenic periosteum (AP) is the unique tissue type that gives rise to antlers and their antecedents, the pedicles. Deer antlers are the only mammalian organ that can fully regenerate. Efficient investigation of the mechanism of antler formation and regeneration requires year-round availability of AP, but naturally AP can only be obtained less than two months in a year. In the present study we took the cryopreservation approach to store the sampled AP in ultra-low temperature to overcome the limited period of availability. First, we evaluated the suitability of vitrification and cell cryopreservation method for cryopreservation of AP, cell migration status of the AP tissue pieces confirmed that vitrification methods did not work as the only few AP cells migrated out, whereas migrated cell numbers in the cell-cryo group (conventional method for cryopreservation of cells) were comparable to those of the fresh AP group. To further evaluate the suitability of cell cryopreservation method for AP tissue, AP samples were allocated into three groups based on the different ratios of cryopreservation reagents (dimethyl sulfoxide [DMSO], dulbecco's modified eagle's medium [DMEM] and fetal bovine serum [FBS]): AP-Cell-1 (1:4:5), AP-Cell-2 (1:2:7) and AP-Cell-3 (1:0:9), the results showed that migrated cell number were again comparable to the fresh AP group. There was no significant difference between the cell-cryo groups (AP-Cell-1 and AP-Cell-3) and the fresh group: (1) in viability (p > 0.05) through trypan blue staining (91.2%, 90.8%, and 92.4%, respectively); (2) in the attachment day, and all on Day 5 after cell seeding; (3) in cell proliferation rate (p > 0.05) through Cell Counting kit 8 (CCK8) measurement; and (4) in number of the formed clones (Clonogenicity). In the in vivo trials, there was no visible difference in temporal differentiation sequence of the formed xenogeneic antlers between the fresh AP and cryopreserved AP (AP-Cell-1 and AP-Cell-3). Overall, we found that the AP tissue was well cryopreserved just using the conventional freezing and thawing methods for cells, and their viability and developmental potential comparable to the fresh AP both in vitro and in vivo. The long-term preservation of the AP tissue is of great significance for the study of the periosteum biology in general and the mechanism underlying xenogeneic generation and regeneration of deer antlers in specific.
