iAware: Making Live Migration of Virtual Machines Interference-Aware in the Cloud (2013)

Large-scale datacenters have been widely used to host cloud services, which are typically allocated to different virtual machines (VMs) through resource multiplexing across shared physical servers. Although recent studies have primarily focused on harnessing live migration of VMs to achieve load balancing and power saving among different servers, there has been little attention on the incurred performance interference and cost on both source and destination servers during and after such VM migration. To avoid potential violations of service-level-agreement (SLA) demanded by cloud applications, this paper proposes iAware, a lightweight interference-aware VM live migration strategy. It empirically captures the essential relationships between VM performance interference and key factors that are practically accessible through realistic experiments of benchmark workloads on a Xen virtualized cluster platform. iAware jointly estimates and minimizes both migration and co-location interference among VMs, by designing a simple multi-resource demand-supply model. Extensive experiments and complementary large-scale simulations are conducted to validate the performance gain and runtime overhead of iAware in terms of I/O and network throughput, CPU consumption, and scalability, compared to the traditional interference-unaware VM migration approaches. Moreover, we demonstrate that iAware is flexible enough to cooperate with existing VM scheduling or consolidation policies in a complementary manner, such that the load balancing or power saving can still be achieved without sacrificing performance.
Improving the performance of the World Wide Web over wireless networks (2002)

The World Wide Web has become the largest source of Internet traffic, but it was not designed for wireless networks. This paper discusses some of the problems encountered when using the Web over wireless networks and describes solutions to those problems. By designing a multithreaded proxy server that prefetches documents to clients, reduces the resolution of large bitmaps, and communicates with clients using a new protocol, the multiple hypertext transfer protocol, we have reduced document load time by over 30%.
Computers against disease. (1993)

In order to improve the efficiency of the collection, compilation and dissemination of information on 35 communicable diseases in China's Sichuan Province, a computerized network has been established. In 1987 a microcomputer link was set up between the Provincial Health and Anti-epidemic Centre at Chengdu and the Health Information Centre in Beijing, and in 1990 a microcomputer network was established between Chengdu and the 21 prefectures in the province. Substantial progress in disease control is already apparent as a consequence of these developments.
Applied and fundamental aspects of BABY BOOM-mediated regeneration (2015)

Keywords: Somatic embryogenesis, Transcription factor, AINTEGUMENTA-LIKE, BABY BOOM, BBM, Sweet Pepper Transformation Title: Applied and Fundamental Aspects of BBM-mediated Regeneration Author: Iris Heidmann Catergories: Plant regeneration, Plant transformation, transcription factor, somatic embryogenesis Plant regeneration from tissues or single cells is essential for plant propagation. Efficient regeneration can be archieved through somatic embryogenesis using the plant growth regulator auxin or overexpression of specific transcription factors, but the underlying mechanisms are poorly understood. The potency of the BABY BOOM (BBM) AINTEGUMENTA-LIKE transcription factor to induce somatic embryogenesis in crop (sweet pepper) and model species (tobacco) was investigated. It was found that the introduction of BBM into sweet pepper, which is recalcitrant for transformation, enhanced the regeneration of transgenic plants. Exogenous cytokinin was necessary to induce somatic embryogenesis in both tobacco and sweet pepper. The mechanism underlying BBM-mediated somatic embryogenesis was studied in Arabidopsis by identifying BBM target genes (ChIPSeq). Genes controlling zygotic embryo identity and maturation (LAFL), as well as auxin biosynthesis (TAA1, YUCCA) and transport (PIN) are BBM targets. Mutant analysis and chemical inhibition studies showed that these genes play positive roles in BBM-induced somatic embryogenesis.
Foreign Direct Investment into Developing Asian Countries: The Role of Market Seeking, Resource Seeking and Efficiency Seeking Factors (2011)

According to eclectic theory of Dunning, FDI could be of four types: market seeking, resource seeking,efficiency seeking and strategic asset seeking. Market seeking factors of FDI such as market size, market growth,structure of domestic market, etc. aim at penetrating the local markets of host countries. While resource seekinginvestments are made in order to have access to cheap raw material, pool of labor, infrastructure, etc. Newsources of competitiveness, economies of scope and specialization and low cost of production are some of theefficiency seeking factors of FDI. An attempt is made to study the impact of market seeking, efficiency seekingand resource seeking factors of host countries on FDI inflows of host countries by taking sample 10 Asiancountries in the time period 1991 to 2008. Panel regression results show that all categories of FDI motivatingfactors have a significant impact on FDI inflows.
<p>Cancer Immunotherapies Targeting Tumor-Associated Regulatory T Cells</p> (2019)

Tumor-associated regulatory T cells (Tregs) are important effectors in the tumor microenvironment (TME), acting as accomplices in the promotion of tumor progression. Currently, the importance of removing the immunosuppressive activity in the TME has received its due attention, and Tregs have been focused on. The cytokine-receptor axes are among the essential signaling pathways in immunocytes, and tumor-associated Tregs are no exception. Therefore, manipulating cytokine-receptor pathways may be a promising effective strategy for treating various malignancies. Here, we summarize the classification, immunosuppressive mechanisms, existing immunotherapies, and potential biomarkers related to tumor-infiltrating Tregs to guide the development of effective cancer immunotherapies.
Precise Nuclear Resonance Thermometer (1957)

The properties of a thermometer based upon the temperature variation of the pure quadrupole resonance frequency (ν0) of the Cl35 nucleus in granular KClO3 have been investigated. In the range ∼10°K&lt;T &lt;300°K, the thermometer has a very high sensitivity, being better than ±0.002° at 273°K and ±0.004° at 77°K. The accuracy at 20°K is estimated as at least ±0.02°. The thermometer is exactly reproducible if care is taken that the KClO3 is of high chemical purity. No hysteresis effects were observed. Establishment of the thermometer requires a single precise determination of the ν0 versus temperature curve using the fundamental temperature standards to measure the temperature.
The presence of tat protein or tumor necrosis factor alpha is critical for herpes simplex virus type 1-induced expression of human immunodeficiency virus type 1 (1994)

Tat-independent transcription of human immunodeficiency virus type 1 (HIV-1) plays an important role in virus life cycle before biologically significant levels of Tat protein have been accumulated. Using a latently infected T-cell line containing an integrated Tat-defective HIV-1 provirus, we examined whether factors known to up-regulate the HIV-1 expression in vitro can replace the requirement for a functional Tat protein and induce the expression of the Tat-defective HIV-1 provirus. Both tumor necrosis factor alpha (TNF-alpha) and herpes simplex virus type 1 (HSV-1) infection stimulated transcription of the Tat-defective HIV-1 provirus to comparable levels, but in HSV-1-infected cells, the cytoplasmic HIV-1 transcripts were not efficiently translated in the absence of Tat protein and were excluded from the large polysomes. However, HSV-1 infection did not affect the distribution of cellular gamma-actin RNA or 28S RNA in the polysomal fractions. The translational block of HIV-1 RNA was not mediated by the virion-associated host cell shutoff protein (vhs); dissociation of HIV-1 transcripts from the polysomes and inefficient translation was also observed in cells infected with the vhs-defective mutant of HSV-1 (vhs-1). Overexpression of Rev protein did not rescue the synthesis of HIV-1 proteins in these cells; however, the observed inhibition of HIV-1 RNA translation was efficiently overcome in the presence of Tat protein or TNF-alpha. These findings suggest that, in contrast to TNF-alpha, HSV-1 infection is not able to induce a full cycle of HIV-1 replication and that cytokines and Tat have a critical role in the activation of HIV-1 provirus by HSV-1.
Ad36 adipogenic adenovirus in human non-alcoholic fatty liver disease (2009)

Ad36 seropositivity is not associated with a significant difference of IR in NAFLD patients, but is associated with a greater adiposity. Ad36 seropositivity is associated with a lower occurrence of NAFLD and bright liver, which, conceivably, is not directly mediated by IR.
The elastic coefficients of double‐porosity models for fluid transport in jointed rock (1995)

Phenomenological equations (with coefficients to be determined by specified experiments) for the poroelastic behavior of a dual porosity medium are formulated, and the coefficients in these linear equations are identified. The generalization from the single‐porosity case increases the number of independent coefficients for volume deformation from three to six for an isotropic applied stress. The physical interpretations are based upon considerations of different temporal and spatial scales. For very short times, both matrix and fractures behave in an undrained fashion. For very long times, the double‐porosity medium behaves like an equivalent single‐porosity medium. At the macroscopic spatial level, the pertinent parameters (such as the total compressibility) may be determined by appropriate field tests. At an intermediate or mesoscopic scale, pertinent parameters of the rock matrix can be determined directly through laboratory measurements on core, and the compressibility can be measured for a single fracture. All six coefficients are determined from the three poroelastic matrix coefficients and the fracture compressibility from the single assumption that the solid grain modulus of the composite is approximately the same as that of the matrix for a small fracture porosity. Under this assumption, the total compressibility and three‐dimensional storage coefficient of the composite are the volume averages of the matrix and fracture contributions.
A consensus genetic map of sorghum that integrates multiple component maps and high-throughput Diversity Array Technology (DArT) markers (2009)

The final consensus map has allowed us to map a larger number of markers than possible in any individual map, to obtain a more complete coverage of the sorghum genome and to fill a number of gaps on individual maps. In addition to overall general consistency of marker order across individual component maps, good agreement in overall distances between common marker pairs across the component maps used in this study was determined, using a difference ratio calculation. The obtained consensus map can be used as a reference resource for genetic studies in different genetic backgrounds, in addition to providing a framework for transferring genetic information between different marker technologies and for integrating DArT markers with other genomic resources. DArT markers represent an affordable, high throughput marker system with great utility in molecular breeding programs, especially in crops such as sorghum where SNP arrays are not publicly available.
Application of New A Priori Algorithm MDNC to Exchange Traded Fund (2009)

How to utilize a variety of derivatives so as to obtain positive investment return in different economies concerns the general investors. The present research utilizes a modified APRIORI algorithm called Multi-Dimension Non-Continuous (MDNC), an algorithm by eliminating the limitations imposed by traditional pattern matching of continuous data, to mine the associated rules in the cross-day discrete trading data and find out some valuable information. This paper further capitalizes on low cost and tax and trading flexibility characteristics of ETF along with a successful and effective data mining methodology to develop a day-trade strategy with high probability of positive investment return. The current approach outperforms Random Walk Transaction strategy with superior investment return and lower risk level, as evidenced by a 95-percent confidence interval. In other words, the investment strategy proposed by the present research is applicable in any economy situation for positive investment return.
The role of trehalose in cell stress. (1996)

Water is usually thought to be required for the living state, but many organisms can withstand anhydrobiosis when essentially all of their body water has been removed. The mechanisms for survival to this kind of stress could be similar in microbes, plants and animals. One common feature is the accumulation of sugars by anhydrobiotic organisms. Trehalose, which is one of the most effective saccharides in preventing phase transition events in the lipid bilayer, is accumulated by anhydrobiotic organisms in large amounts. It lowers membrane phase transitions in dry yeast cells, thus preventing imbibitional damages when cells are rehydrated. Yeast cells have a trehalose carrier in the plasma membrane which endows them with the ability to protect both sides of the membrane. Kinetic analysis of the trehalose transport activity in Saccharomyces cerevisiae cells revealed the existence of a multicomponent system with a constitutive low-affinity uptake component and a high-affinity H(+)-trehalose symporter regulated by glucose repression.
Steroid-Refractory Acute GVHD: Predictors and Outcomes (2011)

Patients with steroid-resistant acute graft versus host disease (aGVHD) have a dismal prognosis, with mortality rates in excess of 90%. We sought to identify a subgroup of patients less likely to benefit from initial therapy with corticosteroids as well as the impact of response on day 14 on outcome. Retrospective evaluation was performed of patients with biopsy-proven aGVHD treated with corticosteroids after allogeneic HSCT at M.D. Anderson Cancer Center from 1998 through 2002 (N = 287). Overall response to first-line therapy on day 14 was 56%. Grade III-IV aGVHD and hyperacute GVHD were the most significant factors predicting failure. Patients who fail to respond to steroids by day 14 should be considered for clinical trials. Severity of aGVHD, hyperacute GVHD, and sex mismatch could be integrated into prognostic scoring systems which may allow for pretreatment identification of patients unlikely to benefit from standard therapy with corticosteroids.
Light Transmission And Scattering Of Polymer Dispersed Liquid Crystals (1989)

The light transmission and scattering properties of a PDLC light shutter in the transparent (field applied) state are studied. It is found from transmission experiments of samples containing sub-micron size droplets that there is a broad distribution of about 10Â° about the field direction in droplet alignment, even in saturating fields. Evidence is presented that this distribution is principally caused by the non-spherical shape of the droplets. Measurements of the total scattering cross section imply that even in the transparent state there exists some multiple scattering or interdroplet scattering effects. Transmission and scattering measurements in samples with supra micron size droplets show effects of anomalous diffraction and are sensitive to distributions in droplet size. The theory of scattering from a nematic droplet in the anomalous diffraction regime agrees favorably with experiment.
Annexin II promotes invasion and migration of human hepatocellular carcinoma cells <i>in vitro</i> via its interaction with HAb18G/CD147 (2009)

HAb18G/CD147, a member of the immunoglobulin family enriched on the surface of tumor cells, is reported to be correlated with invasion, metastasis, growth, and survival of malignant cells. Here, we found that annexin II, a 36-kDa Ca(2+)- and phospholipid-binding protein and in vivo substrate for tyrosine kinase and PKC, is a new interaction protein of HAb18G/CD147 in human hepatocellular carcinoma (HCC) cells. In the present study, we explored the unclear role of annxin II in HCC invasion and migration and the interaction effects between HAb18G/CD147 and annexin II. Our data show that downregulation of annexin II in HCC cells significantly decreased the secretion of MMP, migration ability, and invasive potential, and affected the cytoskeleton rearrangement of tumor cells. The MMP-2 level and invasive potential of HCC cells were regulated by both annexin II and HAb18G/CD147. Also, interaction effects exist between the two molecules in tumor progression, including MMP-2 production, migration, and invasion. These results suggest that annexin II promotes the invasion and migration of HCC cells in vitro, and annexin II and HAb18G/CD147 interact with each other in the same signal transduction pathway working as a functional complex in tumor progression.

Robust real-time UAV based power line detection and tracking (2016)

Power line inspection is an essential but costly task while automated UAV (unmanned aerial vehicle) inspection can greatly reduce such costs. However, navigating along power lines is a challenging task due to the narrow width and limited features of power lines. Existing power line tracking methods have threshold selection problems and cannot work well for complex and changing backgrounds. We make use of power line specific knowledge to build a model to achieve predictive and continuous parameter selection so that the best thresholds are selected for changing scenarios. Experimental studies show that our solution is much better than existing ones. Specifically, we have built the first fully automated UAV that successfully tracks power lines in the real world.

Molecular cloning and expression of the genes encoding the<i>Escherichia coli</i>K4 capsular polysaccharide, a fructose-substituted chondroitin (1990)

The majority of capsular polysaccharides (K antigens) are linear molecules and their genes have a common functional organisation encoding common steps in capsule biogenesis. However, the K4 antigen is a substituted polymer composed of a chondroitin backbone with a fructose side chain. In order to determine whether K4 biosynthesis uses these common mechanisms the K4 antigen genes were cloned. DNA probes taken from the two conserved regions of the Kl genes were used to isolate one plasmid, pRDl, homologous to both probes. Immunological analysis was used to show that pRDl directs the production of the substituted K4 antigen on the cell surface. Southern hybridisation was used to show that the cloned genes are organised in the same way as other K antigen gene clusters. We conclude that the branched K4 antigen is handled by the same post-polymerization mechanisms as other linear K antigens.

An fMRI Study of Facial Emotion Processing in Patients With Schizophrenia (2002)

Failure to activate limbic regions during emotional valence discrimination may explain emotion processing deficits in patients with schizophrenia. While the lack of limbic recruitment did not significantly impair simple valence discrimination performance in this clinically stable group, it may impact performance of more demanding tasks.
