Effect of oil sands slurry conditioning on bitumen recovery from oil sands ores (2010)

The effect of slurry conditioning on bitumen recovery and bitumen froth quality has been studied by using three oil sands ores tested with a laboratory hydrotransport extraction system (LHES) and a Denver flotation cell. Tests with the LHES show that an increase in slurry conditioning time yielded a lowered bitumen recovery for a long flotation time (30 min). Longer slurry conditioning time led to a better bitumen froth quality regardless of flotation time. However the over conditioning could be compensated by higher conditioning temperatures and higher slurry flow velocities. Tests with the Denver flotation cell show that the increase in slurry conditioning time resulted in a higher bitumen recovery and a better bitumen froth quality for both good and poor processing ores for a shorter flotation time of 5 min. For a longer flotation time of 20 min, increasing slurry conditioning time had little impact on bitumen recovery but led to a slightly better bitumen froth quality for the good processing ore whereas no effect on bitumen froth quality of the poor processing ore. Results also show that higher slurry temperatures and stronger mechanical energy input were beneficial to both bitumen recovery and bitumen froth quality for all three oil sands ores tested on both devices.
Production of 0.5-TW Proton Pulses with a Spherical Focusing, Magnetically Insulated Diode (1979)

The production, focusing, and numerical simulation of a 0.5-TW proton beam is reported. This beam is produced with a spherical, magnetically insulated, ion diode fed symmetrically by the dual-pulse-line Proto I generator. The ions are accelerated with electric fields due to a virtual cathode supported by magnetic field surfaces. Approximately 75% of the diode electrical power is delivered to ions and 25% of the ion beam is focused upon thin, 1-cm-diam, 1-cm-long conical targets to produce the first experimental ion-driven implosions.
DAWN: a framework to identify autism genes and subnetworks using gene expression and genetics (2014)

Validation studies demonstrate that DAWN is effective in predicting ASD genes and subnetworks by leveraging genetic and gene expression data. The findings reported here implicate neurite extension and neuronal arborization as risks for ASD. Using DAWN on emerging ASD sequence data and gene expression data from other brain regions and tissues would likely identify novel ASD genes. DAWN can also be used for other complex disorders to identify genes and subnetworks in those disorders.

Photoreactive Crystals: Photodimerization of a Diolefinic Derivative Accompanied by Isomerization (2001)

Abstract The novel photoreactive crystal, 4-(4-(2-(ethoxycarbonyl)vinyl)-cinnamoylamino)benzoic acid, (ECAB) was prepared and its photoreactivity evaluated. By introducing an amide group into a p-phenylenediacrylic acid derivative, a “tape” structure network was constructed. On irradiation the crystals were converted into dimers quantitatively. Characterization of the dimer and the results of X-ray crystallographic analysis showed that photodimerization proceeds with selective cycloaddition of olefinic bonds on the “amide side” only and accompanied by trans-cis isomerization of an olefinic bond on the “ester side”.
Inhibition of herpes simplex virus replication in the mouse cornea by drug containing immunoliposomes. (1987)

Monoclonal antibody to HSV glycoprotein D was derivatized with palmitic acid and incorporated into liposomes. These immunoliposomes bound specifically to intact mouse corneas infected with HSV-1 in vitro. Furthermore, in yield reduction assays, anti-gD immunoliposomes loaded with acyclovir proved far more effective at inhibiting viral replication in the cornea than free drug or drug delivered in untargeted liposomes. Site-specific sustained release immunoliposomes of this type are potentially an improved vehicle for drug delivery in the treatment of ocular HSV.
Synthesis and Photovoltaic Characteristics of Novel Copolymers Containing Poly(phenylenevinylene) and Triphenylamine Moieties Connected at 1,7 Bay Positions of Perylene Bisimide (2005)

Two novel copolymers containing PPV and triphenylamine moieties connected at 1,7 bay positions of perylene bisimide were successfully synthesized by means of the Wittig reaction. Both of them were characterized by FT-IR, 1H NMR, UV−vis, and FL spectra as well as GPC, TGA, and DSC measurements. The introduction of PPV and TPA moieties into the bay positions of perylene bisimide enhanced the solubility of polymers and quenched the fluorescence of perylene bisimide obviously. The photovoltaic devices ITO/PEDOT:PSS/copolymers/Ca/Al were fabricated, and their I−V characteristics indicated that the copolymerization in PERY−PPV and PERY−PPV−TPA improved the device performance for some extent.
Leashing the AlphaWolves (2002)

We present a system in which computer-graphical virtual characters may be controlled by a user and also remain "in character." The system allows the user to have high-level control over the actions of a character, while the emotional state of the character is autonomously maintained by the computer. We show how this system functioned as part of the AlphaWolf installation, presented in the Emerging Technologies program at SIGGRAPH 2001. Results from a 32-subject human user study support the hypothesis that users could control a character's actions without sacrificing its realistic autonomous personality. This system is appropriate to the control of computer-graphical entities that are meant to have personalities distinct from those of the humans that direct them.
Studies on the Removal of Abnormal Prion Protein by Processes Used in the Manufacture of Human Plasma Products (2000)

Plasma fractionation processes used in the manufacture of albumin, immunoglobulins, factor-VIII concentrate, factor-IX concentrates, fibrinogen and thrombin all contain steps which may be capable of removing causative agents of human TSEs.
Label-Free Detection of Clustering of Membrane-Bound Proteins (2010)

We report a new and label-free method to detect and characterize the clustering of membrane-bound proteins and, by extension, the lateral segregation of nanosized particles adsorbed to planar surfaces in liquid environment. The method exploits the contrast between two different mass and surface sensitive detection methods, quartz crystal microbalance with dissipation monitoring and ellipsometry. The time-resolved correlation of both techniques provides insight into subtle changes in the clustering state of surface-bound molecules that is not accessible with either technique alone. A theoretical model can provide quantitative predictions about the size of surface-bound clusters.
GE23077 binds to the RNA polymerase ‘i’ and ‘i+1’ sites and prevents the binding of initiating nucleotides (2014)

Using a combination of genetic, biochemical, and structural approaches, we show that the cyclic-peptide antibiotic GE23077 (GE) binds directly to the bacterial RNA polymerase (RNAP) active-center 'i' and 'i+1' nucleotide binding sites, preventing the binding of initiating nucleotides, and thereby preventing transcription initiation. The target-based resistance spectrum for GE is unusually small, reflecting the fact that the GE binding site on RNAP includes residues of the RNAP active center that cannot be substituted without loss of RNAP activity. The GE binding site on RNAP is different from the rifamycin binding site. Accordingly, GE and rifamycins do not exhibit cross-resistance, and GE and a rifamycin can bind simultaneously to RNAP. The GE binding site on RNAP is immediately adjacent to the rifamycin binding site. Accordingly, covalent linkage of GE to a rifamycin provides a bipartite inhibitor having very high potency and very low susceptibility to target-based resistance.

Experience with liver resection after hepatic arterial chemoembolization for hepatocellular carcinoma (1993)

The use of percutaneous transcatheter hepatic arterial chemotherapy and embolization in the treatment of primary liver cancer has become increasingly popular in recent years. The authors employed this method, using a combination of cisplatin, mitomycin C, 5-fluorouracil, and ethiodized oil (Lipiodol) or absorbable gelatin sponge in 30 patients with huge liver cancers (diameter range, 5.6-12.0 cm) as a preliminary treatment before liver resection. Significant tumor regression occurred after this treatment, converting these tumors into resectable lesions that were excised successfully later. Before surgery, chemoembolization was done once every 4-6 weeks. The patients underwent 1-5 treatment sessions (mean, 2.9) and then waited 1-4 months (mean, 2.4 months) before undergoing surgery. Alpha-fetoprotein levels decreased to normal in seven patients. The tumor diameters were reduced by 31.6 +/- 15.2% (2.3 +/- 1.2 cm) and the percent tumor necrotic area ranged from 40-100%. Adhesions of the tumor to the diaphragm and thickening of the hepatoduodenal ligament and gallbladder wall were the primary operative findings, but they did not significantly complicate the surgery. There was one postoperative death from acute pulmonary embolism. The 1-year, 2-year, and 3-year survival rates were 88.89%, 77.03%, and 77.03%, respectively. Although these patients still are being followed to assess their long-term survival, this treatment appears promising for patients with advanced huge liver cancers who hitherto have been denied surgery on grounds of unresectability.
Semantic Query Optimisation and Rule Graphs. (1998)

Previous researchers note the problem for semantic optimisation of database queries caused by its production of a large number of semantically equivalent alternative queries, tom which one must be quickly chosen. The present paper observes that this is caused by the nontmiform structure of rules, which also (i) prevents fast access to rules, (ii) allows the rule base to become impractically large, and (iii) such rules anyway are of low utility for SQO. Simple rules are less expressive but more useful in this application. Single-antecedent, single-consequent rules are the main component of the rule base. The rule set
Discrete Contributions of Elastic Fiber Components to Arterial Development and Mechanical Compliance (2009)

These results demonstrate that elastin and fibrillin-1 have both differential and complementary roles in arterial wall formation and function, and advance our knowledge of the structural determinants of vascular physiology and disease.
A novel adaptive beamforming algorithm for a smart antenna system in a CDMA mobile communication environment (2000)

An alternative way of adaptive beamforming is presented. The main contribution of the new technique is in its simplicity with a minimal loss of accuracy. The total computational load for computing a suboptimal weight vector from each new signal vector is about O(2N/sup 2/+5N). It can further be reduced down to O(3N) by approximating the autocorrelation matrix with the instantaneous signal vector at each snapshot. The required condition on the adaptive gain for the proposed algorithm to converge is derived analytically. The proposed beamforming algorithm is applied to the base station of a code-division-multiple access (CDMA) mobile communication system. The performance of the proposed method is shown in multipath fading communication channels in terms of the signal-to-interference+noise ratio (SINR), the bit error rate (BER), and the achievable capacity of a given CDMA cell/sector.
Performance analysis of time-multiplexed services for UMTS W-CDMA reverse link (2003)

In UMTS W-CDMA systems, it is possible to offer multiplexed services such as voice, data, and video simultaneously on one physical connection. Several issues such as the QoS requirement for each service, algorithmic complexity, hardware limitations, and performance of the overall system must be considered. In this paper, we investigate some of these issues and present link-level performance for multiplexed services on the reverse-link of an UMTS W-CDMA system. We show that because of an increase in the peak-to-average power ratio when different services are code-multiplexed onto the same physical channel, multiplexed services for UMTS may have to be offered via the time-multiplexing approach. Next, we illustrate how rate matching can be used to satisfy the quality of service requirements for all services. In our results, we illustrate how the rate matching attributes can be selected to satisfy the QoS requirements of 1% speech frame error rate, 10% data frame error rate, and 0.1% video frame error rate. The selection of good rate matching attributes, however, is dependent on many factors such as service rates, channel conditions, and desired error rates. As a result, under some circumstances, excessive transmission power may be required in order to meet the minimum QoS requirements. Next, the performance of the system under compressed mode, where certain frames are compressed in time to allow inter-frequency measurements or handover to other systems, is considered. It is shown that the degradation due to compressed mode is minimal (less than 0.5 dB), and hence compressed mode can safely be used in conjunction with multiplexed services.
Evidence for stable transformation of wheat by floral dip in Agrobacterium tumefaciens (2009)

Hexaploid wheat, one of the world's most important staple crops, remains a challenge for genetic transformation. We are developing a floral transformation protocol for wheat that does not require tissue culture. This paper presents three transformants in the hard red germplasm line Crocus that have been characterized thoroughly at the molecular level over three to six generations. Wheat spikes at the early boot stage, i.e. the early, mid or late uninucleate microspore stages, were immersed in an infiltration medium of strain C58C1 harboring pDs(Hyg)35S, or strain AGL1 harboring pBECKSred. pDs(Hyg)35S contains the NPTII and hph selectable markers, and transformants were detected using paromomycin spray at the whole plant level, NPTII ELISAs, or selection on medium with hygromycin. Strain AGL1, harboring pBECKSred, which contains the maize anthocyanin regulators, Lc and C1, and the NPTII gene, was also used to produce a Crocus transformant. T1 and T2 seeds with red embryos were selected; T1 and T2 plants were screened by sequential tests for paromomycin resistance and NPTII ELISAs. The transformants were low copy number and showed Mendelian segregation in the T2. Stable transmission of the transgenes over several generations has been demonstrated using Southern analysis. Gene expression in advanced progeny was shown using Reverse Transcriptase-PCR and ELISA assays for NPTII protein expression. This protocol has the potential to reduce the time and expense required for wheat transformation.
Aktuelle Entwicklung im Bereich der Bioaerosole und der Abluftreinigung (2015)

Ob Bioaerosolemissionen aus der Tierhaltung negative Einflüsse auf die Gesundheit von Anwohnern im Umkreis von Tierhaltungsanlagen haben, bleibt weiterhin unklar. Aus Gründen der Vorsorge sind sie trotzdem bereits Bestandteil von Genehmigungsverfahren für Stallbaumaßnahmen. Das momentane konservative Vorgehen bei der Berechnung von potentiellen Immissionen mit Ausbreitungsmodellen führt, auch aufgrund fehlender Eingabeparameter, zur Vorhersage von überhöhten Werten. Vorsorglich können Abluftreinigungsanlagen Emissionen mindern. Diese Technik hat in der deutschen Tierhaltung in den letzten 10 Jahren erheblich an Bedeutung gewonnen und verschiedene Systeme sind nunmehr nicht nur für Schweine, sondern auch für Geflügel erhältlich. Zertifizierte Anlagen gewährleisten eine Minderung der meisten luftgetragenen Mikroorganismen um mehr als 90 % bei Schweinen und um 70 % bis 90 % in der Masthähnchenhaltung.
Genetic studies of body mass index yield new insights for obesity biology (2015)

Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in upto 339,224 individuals. This analysis identifies 97 BMI-associated loci (P <5 x 10(-8)), 56 of which are novel. Five loci demonstrate clear evidence of several independent association signals, and many loci have significant effects on other metabolic phenotypes. The 97 loci account for similar to 2.7% of BMI variation, and genome-wide estimates suggest that common variation accounts for >20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous systemin obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.
Selective inhibition of axon outgrowth by antibodies to NGF in a model of temporal lobe epilepsy (1995)

The molecular basis of the axonal reorganization that follows seizure-induced brain injury is unknown. Elevations in neurotrophins following seizures suggest that growth factors may play a role in this process. After pilocarpine-induced seizures, robust axonal sprouting from dentate granule cells and cholinergic forebrain neurons was evident in the inner molecular layer of the dentate gyrus. Intraventricular infusions of an NGF-specific antibody that blocks NGF biological activity in vitro attenuated the cholinergic axonal sprouting and the increases in cell body size of basal forebrain cholinergic neurons that followed seizure-induced injury in vivo. In contrast to its effects on the cholinergic network, the NGF antibody did not decrease the sprouting of dentate granule cell axons into the inner molecular layer. These results suggest that NGF may have a functional and system-specific role in the remodeling of networks that follows repetitive seizures.
On the prokaryotic nature of red algal chloroplasts. (1975)

The sequences of oligonucleotides released by T1 ribonuclease digestion of 32-P-labeled 16S (chloroplast) and 18S (cytoplasmic) ribosomal RNAs from a marine species of Porphyridium (Rhodophyta) have been determined. The resultant catalogs have been compared to those obtained for three prokaryotes:Escherichia coli, Bacillus subtilis, and Anacystis nidulans (a blud-green alga). There is extensive sequence homology between the Porphyridium chloroplast 16S ribosomal RNA and each of the prokaryotic 16S ribosomal RNAs, but little homology between the Porphyridium cytoplasmic 18S ribosomal RNA and any of the 16S species. These data provide a measure of the evolutionary distance separating existing chloroplasts from contemporary bacteria and blue-green algae, and are discussed in terms of the hypothesis that these organelles evolved from endosymbiotic photosynthetic prokaryotes.

Relative deviations of the rms accuracy values between XL-25 and Z-12, such as the kinematic, three-dimensional position and the e ight velocity, are found to be below 2.6 m and 0.5 m/s, respectively.
Natural language programming: Styles, strategies, and contrasts (1981)

Our objective in this study was to obtain detailed empirical information about the nature of natural language “programming” to bring to bear on the issueosf increasing the usability of computer language interfaces. Although we expected numerous difficulties to be detected concerning the potentioalf actually implementing a system to interpret natural language programs, we were not prepared for the magnitude of what we see as being the three major obstacles: style, semantics, and world knowledge. Concerning the first, there is little way in which the vast differences in styles could be increased: programming-language style is simply alien to natural specification. With respect to semantics, we also were unprepared to find out the extent to which the selection of the appropriate “meaning” (to a word, phrase, or sentence) is dependent upon the immediate and prior context. And as for world nowledge, we suspect that the extent to which shared experiences and knowledge are critical to procedural communication and understanding among people has barely been hintaetd by our present data.

Compute intensive code offloading in mobile device cloud (2016)

With the advancement of mobile computing technologies computation intensive mobile applications are also thriving in a rapid pace. Existing cloud and cloudlet based solutions are not best suited for these applications in terms of response time and cost. A rampant technology to execute these applications is mobile device cloud, where the compute intensive part of the applications are migrated to nearby powerful mobile devices for offloaded execution. In this paper, we propose an offloading decision making algorithm to select the appropriate devices for offloading. The emulation results of the proposed algorithm show that, our algorithm outperforms the relevant approaches in terms of application execution time.
Prevention of Vertebrate Neuronal Death by the <i>crmA</i> Gene (1994)

Interleukin-1 beta converting enzyme (ICE) is a mammalian homolog of CED-3, a protein required for programmed cell death in the nematode Caenorhabditis elegans. The activity of ICE can be specifically inhibited by the product of crmA, a cytokine response modifier gene encoded by cowpox virus. Microinjection of the crmA gene into chicken dorsal root ganglion neurons was found to prevent cell death induced by deprivation of nerve growth factor. Thus, ICE is likely to participate in neuronal death in vertebrates.
