Research on Scheduling Strategy based on Trust in Hybrid Cloud (2016)

Hybrid cloud can help companies to maximize the potentiality of IT infrastructure, so the hybrid cloud is increasingly popular in the market. Hybrid cloud scheduling has become one of the important issues which cloud providers face in the current. How to effectively and safely make hybrid cloud scheduling is one of the main research topics in the field of hybrid cloud. This paper introduces an effective hybrid cloud resource management model, and proposes a hybrid cloud resource scheduling strategy based on the particle swarm leapfrog algorithm and trust mechanism in order to solve the problems. The experimental results show that the hybrid cloud scheduling strategy is effective in terms of security and throughput.
Evaluation of Carotid-Femoral Pulse Wave Velocity (2005)

Carotid-femoral pulse wave velocity (PWV), a measure of arterial stiffness, is determined from the time taken for the arterial pulse to propagate from the carotid to the femoral artery. Propagation time is measured variously from the foot of the waveform or point of maximum upslope. We investigated whether these methods give comparable values of PWV at rest, during beta-adrenergic stimulation, and pacing-induced tachycardia. In subjects at rest (n=43), values obtained using the foot-to-foot method (SphygmoCor system) were 1.7+/-0.75 m/s (mean+/-SD) greater than those obtained using the maximum slope (Complior system) at a mean value of 12 m/s. Isoprotenerol (0.5 to 1.5 microg/min; n=10), and pacing (in subjects with permanent pacemakers; n=11) increased heart rate but had differential effects on systolic blood pressure and pulse pressure. The increase in heart rate produced by isoprotenerol (18+/-3 bpm) and pacing (40 bpm) was associated with an increase in PWV measured using both systems (increases of 0.7+/-0.2 m/s and 0.9+/-0.2 m/s for SphygmoCor and Complior, respectively, during isoprotenerol and increases of 2.1+/-0.5 m/s and 1.1+/-0.2 m/s for SphygmoCor and Complior, respectively, during pacing, each P<0.001). Reanalysis of waveforms recorded from the Complior system using the foot-to-foot method produced similar values of PWV to those obtained with the SphygmoCor, confirming that the difference between these systems was attributable to the timing algorithm rather than other aspects of signal acquisition. Carotid-femoral PWV is critically dependent on the method used to determine propagation time, but this does not account for variation of PWV with heart rate.
Conceptual question response times in Peer Instruction classrooms (2014)

Classroom response systems are widely used in interactive teaching environments as a way to engage students by asking them questions. Previous research on the time taken by students to respond to conceptual questions has yielded insights on how students think and change conceptions. We measure the amount of time students take to respond to in-class, conceptual questions [ConcepTests (CTs)] in two introductory physics courses taught using Peer Instruction and use item response theory to determine the difficulty of the CTs. We examine response time differences between correct and incorrect answers both before and after the peer discussion for CTs of varying difficulty. We also determine the relationship between response time and student performance on a standardized test of incoming physics knowledge, precourse self-efficacy, and gender. Our data reveal three results of interest. First, response time for correct answers is significantly faster than for incorrect answers, both before and after peer discussion, especially for easy CTs. Second, students with greater incoming physics knowledge and higher self-efficacy respond faster in both rounds. Third, there is no gender difference in response rate after controlling for incoming physics knowledge scores, although males register significantly more attempts before committing to a final answer than do female students. These results provide insight into effective CT pacing during Peer Instruction. In particular, in order to maintain a pace that keeps everyone engaged, students should not be given too much time to respond. When around 80% of the answers are in, the ratio of correct to incorrect responses rapidly approaches levels indicating random guessing and instructors should close the poll.
On-Road Emissions of PCDDs and PCDFs from Heavy Duty Diesel Vehicles (2002)

This work characterized emission factors of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) from on-road sampling of three heavy duty diesel vehicles (HDDVs) under experimental conditions of city and highway driving; idling operation; high (>400 ppm) and low (<5 ppm) sulfur (S) fuels; and high mileage and rebuilt engine testing. Emission factors, homologue profiles, and isomer patterns were compared to determine whether the experimental conditions had an impact on PCDD/F emissions, or whether these conditions were uninfluential in determining a fleet-representative emission factor. For a single HDDV tested under conditions of a high mileage engine, a newly rebuilt engine, and the newly rebuilt engine with low S diesel fuel, emission factors were 0.023 (+/- 0.022), 0.008 (+/- 0.002), and 0.016 (+/- 0.013) ng toxic equivalency (TEQ)/km, respectively. These results may infer some limited condition-specific differences in PCDD/F emissions, but these differences do not appear to have a significant effect on the HDDV emission factor. An older HDDV with mechanical fuel controls resulted in a single test value of 0.164 ng TEQ/km, significantly higher than all other results. Observed differences in emission factors, homologue profiles, and TEQ-related isomer patterns from this on-vehicle sampling and others' tunnel sampling suggest limitations in our present characterization of fleet PCDD/F emissions.
Toe-To-Heel Waterflooding. Part II: 3D Laboratory Test Results (2003)

Abstract A new waterflooding process, Toe-To-Heel Waterflooding (TTHW) was developed, partly based on recently developed thermal toe-to-heel displacement processes: THAI and CAPRI. TTHW is a novel oil recovery process utilizing a horizontal producer (HP) and a vertical injector (VI). The HP has its horizontal leg located at the top of formation, while its toe is close to the VI, which is perforated at the lower part of the formation. TTHW realizes a gravity stable displacement, where water/oil mobility ratio becomes less important, and its detrimental effect on sweep efficiency is diminished. The main advantage of TTHW process is that the water always breaks-through at the toe, following which water cut gradually increases. A systematic investigation of the TTHW process in a Hele Shaw laboratory model mimicking a simulated porous medium showed that the process substantially improved the vertical sweep efficiency as compared to conventional waterflooding. Following these semi-quantitative tests, a more comprehensive 3-D model testing was undertaken in order to investigate the overall sweep efficiency of the process. The 3-D model consists of a metal box filled with glass beads and saturated with oil at connate water saturation; the thickness of "oil layer" is 16 cm and the length is 42 cm. Oil was displaced with a high salinity brine, either in a toe-to-heel configuration, or in a conventional array, using only vertical wells. A staggered line drive was used, by injecting water in two vertical wells located at one side of box and producing oil through either a horizontal producer with its toe close to injection line, or by using a vertical producer located at the horizontal producer's heel position. Several TTHW tests were carried out at different injection rates. For a given injection rate, the TTHW results were compared to those of conventional waterflooding tests. For the same amount of water injected, the ultimate oil recovery increased by a factor of up to two, as compared to that for conventional waterflooding. Numerical simulation models successfully matched the observed performance in the laboratory. All in all, the results of laboratory investigations and numerical simulations show that the novel TTHW process is sound, and can be further optimized.
Expression of long non-coding ribonucleic acid metastasis-associated lung adenocarcinoma transcript-1 is correlated with progress and apoptosis of laryngeal squamous cell carcinoma (2012)

Results The level of metastasis-associated lung adenocarcinoma transcript-1 in laryngeal squamous cell cancer was significantly higher than that in the corresponding adjacent nonneoplastic tissues. Patients with a poor histological grade or an advanced clinical stage have a higher expression of metastasis-associated lung adenocarcinoma transcript-1. Cell proliferation was significantly inhibited after metastasis-associated lung adenocarcinoma transcript-1 short interfering ribonucleic acid transfection in vitro. The growth of xenografts was signifi cantly suppressed by a repeated injection of a metastasis-associated lung adenocarcinoma transcript-1 short interfering ribonucleic acid lentivirus. Moreover, the apoptosis cells were increased in metastasis-associated lung adenocarcinoma transcript-1 short interfering ribonucleic acid lentivirustreated laryngeal squamous cell cancer xenografts than the control. Conclusion Taken together, these data suggest an important role for metastasisassociated lung adenocarcinoma transcript-1 in the progress of laryngeal squamous cell cancer and the potential application of metastasisassociated lung adenocarcinoma transcript-1 in laryngeal squamous cell cancer therapy.
Expression of the CUB domain containing protein 1 (CDCP1) gene in colorectal tumour cells (2007)

Expression of CUB domain containing protein 1 (CDCP1) is upregulated in carcinoma cells. We quantitated CDCP1 gene expression in matched normal colon and tumour tissue and compared the level of expression to other genes upregulated in colorectal tumourigenesis. Furthermore, we show that the CDCP1 gene generates two transcripts which are co-expressed in normal and matched tumour tissue as well as in the majority of cell lines analysed. However, intracellular localisation studies revealed that only one of these transcripts encodes a protein that is localised to the cell surface.
The fauna of hydrothermal vents on the Mohn Ridge (North Atlantic) (2010)

Abstract The macrofauna of the newly discovered hydrothermal vent field on the Mohn Ridge at 71°N was investigated. Samples were collected during the cruise BIODEEP 2006 using the ROV ‘Bathysaurus’. A total of 180 species-level taxa were identified. The region contains very few vent-endemic species, but some species of Porifera, Crustacea and Mollusca may be vent-associated. Dense aggregations of motile non-vent species such as Heliometra glacialis and Gorgonocephalus eucnemis surrounded the vent area, but the area in general only held small numbers of sedentary animals. Calcareous sponges comprised an unusually high portion of the sponge species found and they constitute one of the first pioneers among the sessile invertebrates settling on these vents. Possible explanations for the structure of the fauna in the region are discussed.
Effects of dielectric properties on electrical characteristics of dielectric barrier discharge generated by low frequency uni-polar high voltage pulses (2019)

Abstract This paper presents experimental results concerning the effects of properties of glass and ceramic dielectric on electrical characteristics of the dielectric barrier discharge (DBD). The effect has been examined with a focus on low frequency uni-polar pulse driving in order to eliminate influences induced by the presence of residual charges and mestastable states in the discharge volume. The results revealed that at low frequency, in the glass reactor, the discharge just occurred after a delay with respect to moment when a high voltage pulse is applied to the reactor, whereas this phenomenon was not observed in the case of discharge in the ceramic reactor. Furthermore, in the glass reactor, DBD was generated with a much higher current peak and shorter discharge current duration in comparison with the electrical characteristics of DBD generated in a ceramic reactor. The differences are presumed to be the result of the difference in ability of trapping and binding surface electrons of dielectric layers.
Expression of rat β(1,4)‐N‐acetylglucosaminyltransferase III in Nicotiana tabacum remodels the plant‐specific N‐glycosylation (2008)

Plant N-linked glycans differ substantially from their mammalian counterparts, mainly with respect to modifications of the core glycan, which typically contains a beta(1,2)-xylose and an alpha(1,3)-fucose. The addition of a bisecting N-acetylglucosamine residue by beta(1,4)-N-acetylglucosaminyltransferase III (GnTIII) is known to control the processing of N-linked glycans in mammals, for example by preventing alpha(1,6)-fucosylation of the core glycan. In order to outcompete plant-specific beta(1,2)-xylose and alpha(1,3)-fucose modifications, rat GnTIII was expressed either with its native localization domain (GnTIII) or with the cytoplasmic tail, transmembrane domain and stem region (CTS) of Arabidopsis thaliana mannosidase II (ManII) (GnTIII(A.th.)). Both CTSs targeted enhanced yellow fluorescent protein (eYFP) to a brefeldin A-sensitive compartment, indicative of Golgi localization. GnTIII expression increased the fraction of N-glycans devoid of xylose and fucose from 13% +/- 7% in wild-type plants to 60% +/- 8% in plants expressing GnTIII(A.th.). N-Glycans of plants expressing rat GnTIII contained three major glycan structures of complex bisected, complex, or hybrid bisected type, accounting for 70%-85% of the total N-glycans. On expression of GnTIII(A.th.), N-glycans displayed a higher heterogeneity and were of hybrid type. Co-expression of A. thaliana ManII significantly increased the amount of complex bisected structures relative to the plants expressing GnTIII or GnTIII(A.th.), whereas co-expression of human ManII did not redirect the pool of hybrid structures towards complex-type structures. The method described offers the advantage that it can be implemented in any desired plant system for effective removal of beta(1,2)-xylose and alpha(1,3)-fucose from the N-glycan.

A Mg-doped lithium-rich layered oxide material with a stable structure exhibits outstanding electrochemical properties for LIBs.
FOXL2 transcriptionally represses Sf1 expression by antagonizing WT1 during ovarian development in mice (2014)

Steroidogenic factor 1 (SF1; Ad4BP/NR5A1) plays key roles in gonadal development. Initially, the Sf1 gene is expressed in mouse fetal gonads of both sexes, but later is up-regulated in testes and down-regulated in ovaries. While Sf1 expression is activated and maintained by Wilms tumor 1 (WT1) and LIM homeobox 9 (LHX9), the mechanism of sex-specific regulation remains unclear. We hypothesized that Sf1 is repressed by the transcription factor Forkhead box L2 (FOXL2) during ovarian development. In an in vitro system (TM3 cells), up-regulation of Sf1 by the WT1 splice variant WT1-KTS was antagonized by FOXL2, as determined by quantitative RT-PCR. Using reporter assays, we localized the Sf1 proximal promoter region involved in this antagonism to a 674-bp interval. A conserved FOXL2 binding site was identified in this interval by in vitro chromatin immunoprecipitation. Introducing mutations into this site abolished negative regulation by FOXL2 in reporter assays. Finally, in Foxl2-null mice, Sf1 expression was increased 2-fold relative to wild-type XX fetal gonads. Our results support the hypothesis that FOXL2 negatively regulates Sf1 expression by antagonizing WT1-KTS during early ovarian development in mice.
Analysis of Sparse Regularization Based Robust Regression Approaches (2012)

Regression in the presence of outliers is an inherently combinatorial problem. However, compressive sensing theory suggests that certain combinatorial optimization problems can be exactly solved using polynomial-time algorithms. Motivated by this connection, several research groups have proposed polynomial-time algorithms for robust regression. In this paper we specifically address the traditional robust regression problem, where the number of observations is more than the number of unknown regression parameters and the structure of the regressor matrix is defined by the training dataset (and hence it may not satisfy properties such as Restricted Isometry Property or incoherence). We derive the precise conditions under which the sparse regularization ( <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">l</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> and <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">l</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> -norm) approaches solve the robust regression problem. We show that the smallest principal angle between the regressor subspace and all <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</i> -dimensional outlier subspaces is the fundamental quantity that determines the performance of these algorithms. In terms of this angle we provide an estimate of the number of outliers the sparse regularization based approaches can handle. We then empirically evaluate the sparse ( <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">l</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> -norm) regularization approach against other traditional robust regression algorithms to identify accurate and efficient algorithms for high-dimensional regression problems.
Synthesis of Chiral C2-Symmetric Bisferrocenyldiamines. X-ray Crystal Structure of Ru(2)Cl2·2CHCl3 (2 = N1,N2-Bis{(R)-1-[(S)-2-(diphenylphosphino)]ferrocenylethyl}- N1,N2-dimethyl-1,2-ethanediamine) (1999)

A new class of chiral C(2)-symmetrical bisferrocenyl diamines, N1,N2-bis[(R)-1-ferrocenylethyl]-N1,N2-dimethyl-1,2-ethanediamine (1) and N1,N2-bis{(R)-1-[(S)-2-(diphenylphosphino)]ferrocenylethyl}-N1,N2-dimethyl-1,2-ethanediamine (2), were prepared from the chiral template (R)-N,N-(dimethylamino)-1-ferrocenylethylamine ((R)-FA). Compound 1 was prepared from the reaction of (R)-FA with MeI followed by nucleophilic substitution with N,N'-dimethylethylenediamine, while 2 was formed from 1 via ortho lithiation followed by electrophilic substitution with chlorodiphenylphosphine. Compound 2 reacts with Ru(DMSO)(4)Cl(2) to give trans-Ru(2)Cl(2) (3) in which the ligand is tetradentate. This complex crystallizes in the orthorhombic system: P2(1)2(1)2(1) (No. 19); a = 11.7230(4) Å, b = 16.5951(6) Å, c = 27.853(1) Å; Z = 4; R = 0.046; R(w) = 0.104. The geometry around the central metal is an octahedron with a pair of chlorine atoms trans to each other. This complex exhibits catalytic activity toward asymmetric cyclopropanation of some olefins and alkyl diazoacetates, giving enantioselectivity up to 95%.
Inside Cover: Ultra‐fast One‐Handed Helix Induction and Its Static Helicity Memory in a Poly(biphenylylacetylene) with a Catalytic Amount of Chiral Ammonium Salts (Angew. Chem. Int. Ed. 15/2023) (2023)

Catalytic ultra-fast helix induction and its static helicity memory in a poly(biphenylylacetylene) were achieved by using chiral ammonium salts, as reported by Katsuhiro Maeda, Eiji Yashima, and co-workers in their Research Article (e202217020). The remarkable acceleration of the helix-induction rate accompanied by strong chiral amplification relies on crown-ether-like specific intermolecular complex formation of the two methoxymethoxy groups of the biphenyl pendants with chiral ammonium species.
A Safe and Facile Route to Imidazole-1-sulfonyl Azide as a Diazotransfer Reagent (2012)

A facile approach to the diazotransfer reagent of imidazole-1-sulfonyl azide was reported. The procedure was well optimized to clarify potential explosion risks. A high production yield as well as small batch variation was achieved even without careful pretreatment of reagents and solvents. HPLC and NMR methods to monitor the process were provided. These features made this protocol suitable for large scale preparation in academia and industry as well.
A novel self-aligned TiN formation by N/sub 2//sup +/ implantation during two-step annealing Ti-salicidation for submicrometer CMOS technology application (1994)

A new technology of self-aligned TiN/TiSi/sub 2/ formation using N/sub 2//sup +/ implantation during two-step annealing Ti-salicidation process has been developed. The formation of TiN was confirmed by RBS analysis. The leakage currents of n/sup +//p junction diodes fabricated using this technology were measured to investigate the phenomena of Al spiking into Si-substrate. The measured reverse-bias leakage current of diode per unit junction area with Al/TiN/TiSi/sub 2/ contact is 1.2 nA/cm/sup 2/ at -5 V, which is less than all of reported data. Also it can sustain the annealing process for 30 min at 500/spl deg/C. Thus, TiN formed with this technology process is suggested as a very effective barrier layer between TiSi/sub 2/ and Al for submicron CMOS technology applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Plasmonic low-profile nanoantenna reflectors (2010)

We describe here the possibility to realize ultralow profile nanoantenna reflectors, which may manipulate optical radiation and emission due to their plasmonic interaction with light. Classic concepts at microwave frequencies, such as reflectarray and holographic antennas are applied here to plasmonic materials, with the goal to achieve a large degree of flexibility and tunability for low-profile reflectors, with potential applications in nano-photonics and optical communications.
