Generative models for name disambiguation (2007)

Name ambiguity is a special case of identity uncertainty where one person can be referenced by multiple name variations in different situations or evenshare the same name with other people. In this paper, we present an efficient framework by using two novel topic-based models, extended from Probabilistic Latent Semantic Analysis (PLSA) and Latent Dirichlet Allocation (LDA). Our models explicitly introduce a new variable for persons and learn the distribution of topics with regard to persons and words. Experiments indicate that our approach consistently outperforms other unsupervised methods including spectral and DBSCAN clustering. Scalability is addressed by disambiguating authors in over 750,000 papers from the entire CiteSeer dataset.
How green is multipath TCP for mobile devices? (2014)

Multipath TCP is a new transport protocol that enables systems to exploit available paths through multiple network interfaces. MPTCP is particularly useful for mobile devices, which frequently have multiple wireless interfaces. However, these devices have limited power capacity and thus judicious use of these interfaces is required. In this work, we develop a model for MPTCP energy consumption derived from experimental measurements using MPTCP on a mobile device with both cellular and WiFi interfaces. Using our MPTCP energy model, we identify the operating region where MPTCP can be more power efficient than either standard TCP or MPTCP. Based on our findings, we also design and implement an improved energy-efficient MPTCP that reduces power consumption by up to 8% in our experiments, while preserving the availability and robustness benefits of MPTCP.
Quantitative Assessment of the Efficacy of Amorphous Calcium Phosphate/Methacrylate Composites in Remineralizing Caries-like Lesions Artificially Produced in Bovine Enamel (1996)

Recent studies show that methacrylate-based composites with amorphous calcium phosphate (ACP) as a filler can release supersaturating levels of calcium and phosphate ions in proportions favorable for apatite formation. These findings suggest that such composites could be effectively used as coatings for remineralizing teeth damaged by tooth decay. To examine this hypothesis, we tested composites in vitro for their efficacy to remineralize artificially formed caries-like lesions in extracted bovine incisors. Single 120-microns-thick sagittal tooth sections were placed in holders that exposed only the carious enamel surface. The exposed surfaces were coated with a 1-mm- to 1.5-mm-thick layer of the composite containing, by mass, 40% apatite, silica, or P2O7(-4)-stabilized ACP and 60% photoactivated resin comprised of Bis-GMA, TEGDMA, HEMA, and ZrM. The photocured composite-coated sections were immersed either in a remineralizing solution for 4 weeks at 37 degrees C (static model) or cyclically immersed in demineralizing (0.5 h) and remineralizing solutions (11.5 h) for 2 weeks (dynamic model). Quantitative digital image analysis of matched 102 microns x 220 microns areas from contact microradiographs taken of the sections before and after immersion showed that lesions coated with ACP-filled composites fractionally recovered 71% +/- 33% of their lost mineral compared with 14% +/- 13% for apatite controls in the static model and 38% +/- 16% compared with -6% +/- 24% in the dynamic model. The results suggest that sealants based on ACP-filled methacrylate composites have the potential to remineralize carious enamel lesions.
Optimization and comparison of distributed generator in distribution system using backward and forward sweep method (2016)

This paper represents a easy methodology for optimal location and comparison of distributed generator (DG) in distribution system. Main idea behind this methodology is just to decrease the power loss and to reduce the environmental effects. Backward forward sweep method has been used to carry out base power flow analysis due to its high convergence rate and simplicity. The proposed methodology has been simulated on IEEE 33-bus distribution systems in the MATLAB environment. The outputs obtained clearly show the effectiveness of the proposed methodology.
Nucleotide Sequence at the 5' Extremity of Tobacco-Mosaic-Virus RNA. 1. The Noncoding Region (Nucleotides 1-68) (1978)

In the preceding paper it was shown that the first A-U-G codon in tobacco mosaic virus RNA is separated from the 5' terminus by a sequence of 68 nucleotides devoid of internal guanosine residues. In this paper we present the sequence of 165 residues immediately following the first potential initiation codon. The characterized sequence contains four nonsense codons but none are in phase with the prospective initiation codon. Several lines of evidence, including direct characterization of the portion of the RNA molecule which binds to and is protected by the ribosome in the course of initiation, all support the idea that the A-U-G at position 69-71 is a functional initiation signal for viral protein synthesis.
FineLine (2018)

Recovery is an intricate aspect of transaction processing architectures. In its traditional implementation, recovery requires the management of two persistent data stores---a write-ahead log and a materialized database---which must be carefully orchestrated to maintain transactional consistency. Furthermore, the design and implementation of recovery algorithms have deep ramifications into almost every component of the internal system architecture, from concurrency control to buffer management and access path implementation. Such complexity not only incurs high costs for development, testing, and training, but also unavoidably affects system performance, introducing overheads and limiting scalability.
Polysome-associated mRNAs are substrates for the nonsense-mediated mRNA decay pathway in Saccharomyces cerevisiae. (1997)

In eukaryotic cells, premature termination of translation at nonsense codons has been implicated as the cause of a variety of posttranscriptional events, including rapid mRNA decay in the cytoplasm or the nucleus, altered splice site selection, and exon skipping. In the yeast Saccharomyces cerevisiae, nonsense codons promote accelerated mRNA decay, and we sought to determine the cellular location in which this degradation occurs. In this report, we demonstrate that six different mRNAs, including nonsense-containing transcripts of the LEU2, HIS4, PGK1, and CYH2 genes, and two wild-type mRNAs (the MAT(alpha)1 and CYH2 mRNAs), were stabilized when the translation elongation inhibitor cycloheximide was added to cellular growth media. Subsequent removal of cycloheximide resulted in resumption of translation and degradation of wild-type and nonsense-containing mRNAs. A significant fraction of the CYH2 pre-mRNA that accumulated in the presence of cycloheximide was associated with polysomes, but disappeared from that fraction when decay resumed in the absence of the drug. Moreover, the abundance of the spliced and unspliced forms of the untranslated U3 snRNA was shown to be unaffected in strains harboring mutations that stabilize nonsense-containing mRNAs. Taken together, these observations indicate that nonsense-containing mRNAs in yeast are degraded within the polysome compartment of the cell.
Microfluidic mixers: from microfabricated to self-assembling devices (2004)

This paper begins with a survey of both passive and active microfluidic mixers that have been implemented in recent years. It then describes a micromixing device based on dynamic self-assembly. This device is easy to fabricate and has excellent working characteristics in the continuous-flow mode. The paper concludes with a brief discussion of possible applications of self-assembly in microfluidics.

NADP-malic enzyme: immunolocalization in different tissues34 plant maize and the C3 plant wheat (1997)

In situ immunotocalization and Western blot analysis of separated cellular and subcellular fractions, were used to determine the localization of different isoforms of NADP-malic enzyme in both wheat (CJ and maize (C 4 ) plants.In both techniques, an affinity purified anti-(maize 62 kDa NADP-ME) IgG from the maize green leaf isoform also reacted with a 72 kDa protein in tissues of C 4 plants as well as C 3 plants.The lightinducible 62 kDa isoform is located in bundle sheath chloroplasts of maize leaves.In etiolated leaves and in roots of maize there is evidence for the occurrence of a 72 kDa isoform which co-migrates on 2-D (SDS and isoelectric focusing) PAGE.The 72 kDa isoform is also present in low levels in green leaves.This form may occur in multiple intracellular compartments; but in situ immunolocalization experiments and Western blot and activity assays on fractionated protoplasts indicate that a significant amount of this isoform occurs in plastids.With regards to C 3 plants such as wheat, a 72 kDa isoform in leaves is largely confined to the chloroplasts based on in situ immunolocalization and Western blots and enzyme activity assays with fractionated protoplasts.In maize, it appears that the constitutive expression pattern of a possible C 3 ancestral gene for NADP-malic enzyme has been maintained, and a high level expression of a light-inducible isoform located in bundle sheath chloroplasts (62 kDa) has been acquired during its evolution.
Vision-based tracking and motion estimation for moving targets using small UAVs (2006)

This paper addresses the development of a vision-based target tracking system for a small unmanned air vehicle. The algorithm performs autonomous tracking of a moving target, while simultaneously estimating GPS coordinates of the target. A low cost off the shelf system is utilized, with a modified radio controlled aircraft airframe, gas engine and servos. Tracking is enabled using a low-cost, miniature pan-tilt gimbal. The control algorithm provides rapid and sustained target acquisition and tracking capability. A target position estimator was designed and shown to provide reasonable targeting accuracy. The impact of target loss events on the control and estimation algorithms is analyzed in detail
Collapse of LiNi<sub>1–<i>x</i>–<i>y</i></sub>Co<sub><i>x</i></sub>Mn<sub><i>y</i></sub>O<sub>2</sub> Lattice at Deep Charge Irrespective of Nickel Content in Lithium-Ion Batteries (2019)

Volume variation and the associated mechanical fracture of electrode materials upon Li extraction/insertion are a main cause limiting lifetime performance of lithium-ion batteries. For LiNi<sub>1- x- y</sub>Co <sub>x</sub>Mn <sub>y</sub>O<sub>2</sub> (NCM) cathodes, abrupt anisotropic collapse of the layered lattice structure at deep charge is generally considered characteristic to high Ni content and can be effectively suppressed by elemental substitution. Herein, we demonstrate the lattice collapse is a universal phenomenon almost entirely dependent on Li utilization, and not Ni content, of NCM cathodes upon delithiation. With Li removal nearing 80 mol %, very similar c-axis lattice shrinkage of around 5% occurs concurrently for NCMs synthesized in-house regardless of nickel content (90, 70, 50, or 33 mol %); meanwhile, the a-axis lattice contracts for high-Ni NCM, but it expands for low-Ni NCM. We further reveal Co-Mn cosubstitution in NCM barely, if at all, affects several key structural aspects governing the lattice distortion upon delithiation. Our results highlight the importance of evaluating true implications of compositional tuning on high-Ni layered oxide cathode materials to maximize their charge-storage capacities for next-generation high-energy Li-ion batteries.
Oral intake of heat-killed cells of<i>Lactococcus lactis</i>strain H61 promotes skin health in women (2012)

We conducted a double-blind, placebo-controlled trial to evaluate the effect of heat-killed cells of Lactococcus lactis strain H61 on various skin properties of Japanese women. Volunteers (age 31-62 years) were randomly assigned to receive test food with or without 60 mg of heat-killed strain H61 (fifteen women in each group; H61 and control groups, respectively) daily for 8 weeks. Results were analysed for three age categories (30s, 40s and 50-60s). Compared with that at week 0, skin hydration at the inner forearm at weeks 4 and 8 decreased in all volunteers (except those in their 50-60s) because of the environmental change from autumn to winter. The oldest H61 group maintained skin hydration at the inner forearm throughout the study. Skin elasticity and melanin content in the cheek decreased and sebum content increased throughout the test period due to seasonal environmental change, regardless of age or H61 treatment. Self-evaluation scores for apparent hair follicles and dryness of the throat at week 8 were higher in the overall H61 group than in the combined placebo group. The 30s H61 group noted marked improvements in self-surveyed skin elasticity at week 8 compared with at week 0 and with the placebo group at week 8. The results of the present study indicate that oral intake of heat-killed cells of L. lactis strain H61 can improve some skin properties and body characteristics in women. This strain would probably be useful in increasing the quality of life in an ageing population.
Germ Cell-Intrinsic and -Extrinsic Factors Govern Meiotic Initiation in Mouse Embryos (2008)

Retinoic acid (RA) is an essential extrinsic inducer of meiotic initiation in mammalian germ cells. However, RA acts too widely in mammalian development to account, by itself, for the cell-type and temporal specificity of meiotic initiation. We considered parallels to yeast, in which extrinsic and intrinsic factors combine to restrict meiotic initiation. We demonstrate that, in mouse embryos, extrinsic and intrinsic factors together regulate meiotic initiation. The mouse RNA-binding protein DAZL, which is expressed by postmigratory germ cells, is a key intrinsic factor, enabling those cells to initiate meiosis in response to RA. Within a brief developmental window, Dazl-expressing germ cells in both XX and XY embryos actively acquire the ability to interpret RA as a meiosis-inducing signal.
High <i>T</i>g Fluorene-based Hole-transporting Materials for Organic Light-emitting Diodes (2005)

Abstract A new series of fluorene-based hole-transporting materials, 9,9-bis[4-(di-p-tolylamino)phenyl]-2,7-bis(diphenylamino)fluorene (1), 9,9-bis[4-(di-p-tolylamino)phenyl]-2,7-bis(di-p-tolylamino)fluorene (2), 9,9-bis[4-(di-p-tolylamino)phenyl]-2,7-bis(2-naphthylphenylamino)fluorene (3), and 9,9-bis[4-(di-p-tolylamino)phenyl]-2,7-bis(9-carbazolyl)fluorene (4), was prepared and employed in the fabrication of organic light-emitting devices (OLEDs). These materials were designed to have bulky triarylamine moieties at the C-9 position, which provides them with excellent thermal stability and high glass-transition temperatures (Tg = 139–171 °C). 1 and 3 are comparable to 1,4-bis(1-naphthylphenylamino)biphenyl (NPB) in terms of device performance (maximum luminence and current efficiency) in a standard hole-transporting layer (HTL)/tris(8-hydroxyquinolino)aluminum (Alq3) double-layer device, but are superior to NPB in terms of higher glass-transition temperatures (Tg = 139 and 145 °C, respectively), while 2 shows higher luminance and current efficiency as well as Tg (140 °C) than those of NPB (100 °C).
Optimization studies of a multikilowatt PIE CO&lt;inf&gt;2&lt;/inf&gt;laser (1986)

Details of an investigation of the operational performance of a 10 kW CW PIE CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> laser are presented. The results obtained from the experiment, successfully scaled by an order of magnitude from an earlier proof-of-principle device, clearly document that the PIE excitation process can be effectively utilized in the design of very large volume lasers. Optimization data further reveal that overall wallplug efficiency is commensurate with that obtained from <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</tex> -beam sustained lasers; but at far less complexity and cost.

Using Input Buffers for Streaming XSLT Processing (2009)

We present a buffering streaming engine for processing top-down XSLT transformations. It consists of an analyzer and a transformer.The analyzer examines given top-down XSLT and XSD, and generates fragments which identify parts of XSD need to be buffered when XSLT is applied. The fragments are passed to the transformer which processes XSLT on an input XML document conforming to XSD. It uses auxiliary memory buffers to store temporary data and buffering is controlled according to the fragments. We describe implementation of the engine within the Xord framework and provide evaluation tests which show that the new engine is much more memory-efficient comparing to the common XSLT processors.
Issues and Implications of the Thermal Control System on Responsive Space Missions (2006)

Abstract : One aspect that poses a significant hurdle to achieving the goals of Operationally Responsive Space (ORS) is the thermal control system (TCS). Traditionally the TCS must be vigorously designed, analyzed, tested, and optimized from the ground up for every satellite mission. This reinvention of the wheel is costly and time intensive. Current design cycles require years. Next generation satellite thermal management must be robust, modular, and scalable in order to cover a wide range of applications, orbits, and mission requirements. To provide a better understanding of the issues and implications of the TCS and to help bound the problem for the development of robust and modular thermal designs, a preliminary analysis was conducted to determine the upper and lower design bounds for a small responsive satellite. In addition, the range of external heat loads for small satellites in low earth orbit were evaluated. From this analysis, the worst hot and cold cases conditions were identified. Using these two cases, various design parameters were evaluated, three different design approaches were compared, and the feasibility of a one-size-fits-all approach was assessed.
Lifetime of carbon capture and storage as a climate-change mitigation technology (2012)

In carbon capture and storage (CCS), CO(2) is captured at power plants and then injected underground into reservoirs like deep saline aquifers for long-term storage. While CCS may be critical for the continued use of fossil fuels in a carbon-constrained world, the deployment of CCS has been hindered by uncertainty in geologic storage capacities and sustainable injection rates, which has contributed to the absence of concerted government policy. Here, we clarify the potential of CCS to mitigate emissions in the United States by developing a storage-capacity supply curve that, unlike current large-scale capacity estimates, is derived from the fluid mechanics of CO(2) injection and trapping and incorporates injection-rate constraints. We show that storage supply is a dynamic quantity that grows with the duration of CCS, and we interpret the lifetime of CCS as the time for which the storage supply curve exceeds the storage demand curve from CO(2) production. We show that in the United States, if CO(2) production from power generation continues to rise at recent rates, then CCS can store enough CO(2) to stabilize emissions at current levels for at least 100 y. This result suggests that the large-scale implementation of CCS is a geologically viable climate-change mitigation option in the United States over the next century.
Laboratory readiness and response for novel coronavirus (2019-nCoV) in expert laboratories in 30 EU/EEA countries, January 2020 (2020)

Timely detection of novel coronavirus (2019-nCoV) infection cases is crucial to interrupt the spread of this virus. We assessed the required expertise and capacity for molecular detection of 2019-nCoV in specialised laboratories in 30 European Union/European Economic Area (EU/EEA) countries. Thirty-eight laboratories in 24 EU/EEA countries had diagnostic tests available by 29 January 2020. A coverage of all EU/EEA countries was expected by mid-February. Availability of primers/probes, positive controls and personnel were main implementation barriers.

Metabolic Engineering of Escherichia coli for Production of Mixed-Acid Fermentation End Products (2014)

Mixed-acid fermentation end products have numerous applications in biotechnology. This is probably the main driving force for the development of multiple strains that are supposed to produce individual end products with high yields. The process of engineering Escherichia coli strains for applied production of ethanol, lactate, succinate, or acetate was initiated several decades ago and is still ongoing. This review follows the path of strain development from the general characteristics of aerobic versus anaerobic metabolism over the regulatory machinery that enables the different metabolic routes. Thereafter, major improvements for broadening the substrate spectrum of E. coli toward cheap carbon sources like molasses or lignocellulose are highlighted before major routes of strain development for the production of ethanol, acetate, lactate, and succinate are presented.
