Evaluation of delta compression techniques for efficient live migration of large virtual machines (2011)

Despite the widespread support for live migration of Virtual Machines (VMs) in current hypervisors, these have significant shortcomings when it comes to migration of certain types of VMs. More specifically, with existing algorithms, there is a high risk of service interruption when migrating VMs with high workloads and/or over low-bandwidth networks. In these cases, VM memory pages are dirtied faster than they can be transferred over the network, which leads to extended migration downtime. In this contribution, we study the application of delta compression during the transfer of memory pages in order to increase migration throughput and thus reduce downtime. The delta compression live migration algorithm is implemented as a modification to the KVM hypervisor. Its performance is evaluated by migrating VMs running different type of workloads and the evaluation demonstrates a significant decrease in migration downtime in all test cases. In a benchmark scenario the downtime is reduced by a factor of 100. In another scenario a streaming video server is live migrated with no perceivable downtime to the clients while the picture is frozen for eight seconds using standard approaches. Finally, in an enterprise application scenario, the delta compression algorithm successfully live migrates a very large system that fails after migration using the standard algorithm. Finally, we discuss some general effects of delta compression on live migration and analyze when it is beneficial to use this technique.
Treatment of Malignant Carcinoid Tumors With Recombinant Interferon alfa-2b: Development of Neutralizing Interferon Antibodies and Possible Loss of Antitumor Activity (1989)

Twenty patients with malignant carcinoid tumors were treated for 6 months with recombinant interferon alfa-2b (IFN alpha-2b; Intron-A; Schering Corp., Bloomfield, NJ) at a mean dose of 5.9 megaunits three times per week. Eleven of the 20 patients (55%) had a greater than 50% reduction of tumor markers (urinary 5-hydroxyindoleacetic acid or plasma neuropeptide K), showing objective tumor response. Six patients (30%) had stable disease with no significant change in tumor markers or tumor size, and three (15%) had progressive disease with an increase in tumor markers and size. These results are similar to those reported earlier for treatment with natural leukocyte IFN in patients with carcinoid tumors. Only two patients (35%) had a slight reduction of tumor size after 6 months of treatment. Three patients developed neutralizing antibodies to IFN alpha-2b. Two of these patients initially showed an objective response, which lasted until IFN antibodies developed. In one of these patients, a change to human leukocyte IFN resulted in normalization of antibody titers within 3 months, and the patient had a second objective clinical response. There was no correlation between development of IFN antibodies and development of autoimmune phenomena such as increased titers of antinuclear antibodies or thyroid autoantibodies. IFN alpha-2b seems to be as potent as human leukocyte IFN in the treatment of patients with malignant carcinoid tumors, but it is important to recognize that antibodies neutralizing IFN may develop in some patients, with concomitant loss of antitumor effects. A change to natural leukocyte IFN might be beneficial in these patients.
Revisiting curcumin chemistry part I: a new strategy for the synthesis of curcuminoids. (2011)

A new strategy for the synthesis of curcuminoids is described involving the reaction of acetylacetone difluroboronite with an aromatic aldehyde in the presence of n-butylamine as catalyst. The new intermediate products, curcuminoid difluroboronites, of symmetrically substituted curcuminoids like curcumin and bisdemethoxycurcumin are stable, can be isolated and hydrolysed with aq. methanol at pH 5.8 to get the curcuminoids of high purity. The method is applicable for unsymmetrical curcuminoids like demethoxycurcumin also with some modification involving column chromatography. The intermediate curcuminoid difluroboronites, as also the natural β-diketone pongamol difluroboronite, prepared for the first time were characterized on the basis of physical and chemical properties and spectroscopic data. The advantage of using borontrifluoride to protect the enol group in acetylacetone over the generally used boric oxide is brought out. The importance of conducting biological activity studies using pure curcuminoids is explained.
Enhanced Simplified Maximum Likelihood Detection (ES-MLD) in Multiuser MIMO Downlink in Time-Variant Environment (2007)

Support for a large number of users is required for the next generation wireless access systems and very high channel capacity must be achieved. The Multiuser-MIMO (MU-MIMO) technique has attracted much attention because of its high spectrum efficiency. However, in downlink MU-MIMO, channel state information (CSI) estimation error occurs in a time varying environment and the transmission quality is degraded. In this paper, we propose a new transmission and decoding method based on simplified maximum likelihood detection (S-MLD), which was proposed for single user MIMO systems. Since the dimensions of the signal path search space are expanded by adding interference signal space to the desired signal space, the proposed method is robust against the interference caused by the channel variation in MU-MIMO. The effectiveness of the proposed method is confirmed by computer simulation.
Recent advances and applications of mid-infrared based trace gas sensor technology (2008)

Multisensor Processing Algorithms for Underwater Dipole Localization and Tracking Using MEMS Artificial Lateral-Line Sensors (2006)

An engineered artificial lateral-line system has been recently developed, consisting of a 16-element array of finely spaced MEMS hot-wire flow sensors. This represents a new class of underwater flow sensing instruments and necessitates the development of rapid, efficient, and robust signal processing algorithms. In this paper, we report on the development and implementation of a set of algorithms that assist in the localization and tracking of vibrational dipole sources underwater. Using these algorithms, accurate tracking of the trajectory of a moving dipole source has been demonstrated successfully.
Performance of a wideband multilayer polarizer for soft x rays (1992)

Performance of a Ru/C multilayer polarizer of double-crystal x-ray monochromator type has been evaluated in the soft x-ray region using synchrotron radiation. The throughput efficiencies for s-polarized light were found to be 11.5% at 100 eV and higher than 4% over an energy range of 80–150 eV without higher-order contamination. Its polarizance was higher than 99.0% at 88 eV and more than 94% over a range of 80–110 eV.
Mat-core: A matrix core extension for general-purpose processors (2007)

This paper proposes new processor architecture to exploit the increasingly number of transistors per integrated circuit and improve the performance of data parallel applications on general-purpose processors. The proposed processor (called Mat-core) is based on the use of multi-level ISA to explicitly communicate data parallelism to processor in a compact way instead of the dynamic extraction using complex hardware or the static extraction using sophisticated complier techniques. Since the fundamental data structures for data parallel applications are scalar, vector, and matrix data, Mat-core extends a scalar core (for executing scalar instructions) with a matrix unit (for executing vector/matrix instructions). Like vector microarchitectures, the extended matrix unit is organized in parallel lanes; each lane contains a pipeline of each functional unit and a slice of the register file. However, the Mat-core processor can effectively process not only vector but also matrix data on the parallel lanes. The increasingly budget of transistors can be exploited to scale the Mat-core processor by providing more cores in a physical package. On a multi-core processor, performance would be improved by parallel processing threads of codes using multi-threading techniques.
Noise analysis of a digital tanlock loop (1988)

The noise performance analysis of a nonuniform digital phase-locked loop (DPLL), called the digital tanlock loop (DTL), is investigated by both analytic and computer-simulation methods. The results are presented in terms of phase error probability mass function and mean time to skip cycle versus input signal-to-noise ratio (SNR). These results are compared to the ones obtained with the conventional sinusoidal DPLL loop (DPLL). It is found that, for low-to-moderate input SNR, the DTL has only a slight improvement over the DPLL. The DTL, however, has larger linear characteristics than the conventional DPLL, which makes it attractive for applications that require an increased tracking range or as a first stage in carrier tracking systems based on optimum estimation procedures such as a Kalman smoother.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Kinetics of Bacillus cereus phosphatidylinositol-specific phospholipase C with thiophosphate and fluorescent analogs of phosphatidylinositol (1992)

Thiophosphate analogs (C-S-P bond) of phosphatidylinositol (Cn-thio-PI: racemic hexadecyl-, dodecyl-, and octylthiophosphoryl-1-myo-inositol) and a fluorescent analog (pyrene-PI: rac-4-(1-pyreno)-butylphosphoryl-1-myo-inositol) were all substrates for phosphatidylinositol-specific phospholipase C from Bacillus cereus. Hydrolysis of thio-PI was followed by coupling the production of alkylthiol to a disulfide interchange reaction with dithiobispyridine. Hydrolysis of pyrene-PI was followed using a HPLC-based assay with fluorescence detection. The activity of PI-PLC with thio-PI analogs showed an interfacial effect. C16-Thio-PI, which had a critical micelle concentration (CMC) of 7 microM, gave a hyperbolic activity versus concentration curve between 0 and 2 mM, while C8-thio-PI, which had a CMC above 10 mM, showed very low activity which increased greatly upon introduction of an interface in mixed micelles with hexadecylphosphocholine (HDPC). Pyrene-PI, which aggregates above 0.3 mM, gave a sigmoidal activity curve with much higher activity above the CMC. All three thio-PI homologs as mixed micelles with HDPC gave hyperbolic activity curves with PI-PLC that were a function of bulk concentration of substrate at constant surface concentration and surface concentration of substrate at constant bulk concentration. The maximal activity of PI-PLC with pure C16-thio-PI micelles was 6.25 mumol min-1 mg-1, while that with pyrene-PI was estimated to be 68 mumol min-1 mg-1. With pure C16-thio-PI micelles, 0.022 mM substrate gave half Vmax, similar to that in mixed micelles with HDPC.
NCRs and DNAM-1 mediate NK cell recognition and lysis of human and mouse melanoma cell lines in vitro and in vivo (2009)

NK cells use a variety of receptors to detect abnormal cells, including tumors and their metastases. However, in the case of melanoma, it remains to be determined what specific molecular interactions are involved and whether NK cells control metastatic progression and/or the route of dissemination. Here we show that human melanoma cell lines derived from LN metastases express ligands for natural cytotoxicity receptors (NCRs) and DNAX accessory molecule-1 (DNAM-1), two emerging NK cell receptors key for cancer cell recognition, but not NK group 2 member D (NKG2D). Compared with cell lines derived from metastases taken from other anatomical sites, LN metastases were more susceptible to NK cell lysis and preferentially targeted by adoptively transferred NK cells in a xenogeneic model of cell therapy. In mice, DNAM-1 and NCR ligands were also found on spontaneous melanomas and melanoma cell lines. Interference with DNAM-1 and NCRs by antibody blockade or genetic disruption reduced killing of melanoma cells. Taken together, these results show that DNAM-1 and NCRs are critical for NK cell-mediated innate immunity to melanoma cells and provide a background to design NK cell-based immunotherapeutic strategies against melanoma and possibly other tumors.
Unraveling the Intrinsic and Robust Nature of van Hove Singularities in Twisted Bilayer Graphene by Scanning Tunneling Microscopy and Theoretical Analysis (2012)

Extensive scanning tunneling microscopy and spectroscopy experiments complemented by first-principles and parametrized tight binding calculations provide a clear answer to the existence, origin, and robustness of van Hove singularities (vHs) in twisted graphene layers. Our results are conclusive: vHs due to interlayer coupling are ubiquitously present in a broad range (from 1° to 10°) of rotation angles in our graphene on 6H-SiC(000-1) samples. From the variation of the energy separation of the vHs with the rotation angle we are able to recover the Fermi velocity of a graphene monolayer as well as the strength of the interlayer interaction. The robustness of the vHs is assessed both by experiments, which show that they survive in the presence of a third graphene layer, and by calculations, which test the role of the periodic modulation and absolute value of the interlayer distance. Finally, we clarify the role of the layer topographic corrugation and of electronic effects in the apparent moiré contrast measured on the STM images.

A Highly Accurate Stress Measurement System for Producing Precise X-Ray Masks (1995)

A new system that measures stress in film deposited on Si wafers has been developed to produce highly accurate X-ray masks. The system consists of very rigid air sliders, an electrostatic sensor, and a soft-handling wafer chuck. With the system, wafer warp is precisely measured before and after film deposition, and the stress distribution is calculated from those measurements. Wafer warps can be measured with a repeatability of a few nanometers by this system. The stress distribution of absorber film on 2-mm-thick Si wafers can be determined with an accuracy of ±5 MPa. The stress distribution agrees well with the pattern position shifts in the membrane.
Hypertension and Circulating mRNA for 11β‐Hydroxysteroid Dehydrogenase Type II (2008)

Circulating DNA and mRNA for 11beta-hydoxysteroid dehydrogenase (HSD) type II were measured in patients with hypertension and in healthy subjects. DNA and RNA levels in hypertensive patients and controls were quantified using real-time RT-PCR. Messenger RNA for 11beta-HSD type II was significantly lower in the hypertensive patients (median: 0.18) (P= 0.032) than in healthy subjects (median: 0.42). Plasma DNA was also significantly lower (P= 0.016) in hypertension. It is suggested that measurement of mRNA for 11beta-HSD type II in hypertension may identify subjects who may be salt-sensitive.
Color filter selection for color correction in the presence of noise (1993)

The effect of noise on the number of effective channels (color filters) used to record a color image is investigated. Transmittances of color filters are calculated which minimize the mean square error that occurs when estimating, from the recorded data, the colors in the image under a collection of viewing illuminants. Since the results indicate that a significant improvement in color correction accuracy is achieved by using four channels, there is good reason to consider using four-tuples for the representation of colorimetric information.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Preliminary instrumentation for the efficient use of Web-based electronic health records (2004)

NIST has devised preliminary elements (technical hooks) of a convenient logging method for Web-based electronic health record (EHR) dialogues. These can identify fields, record times spent at each (by whomever), and log a sequence of visits. The next step will be to refine this promising start, to begin building upon it a more polished and user-friendly system. We present our results to gain impressions from users of the worth of simple, open tools for tuning and improving e-record flows and their corresponding with practice workflows.
Human platelets secrete chemotactic activity for eosinophils (1993)

Thrombin-stimulated platelets liberate factors that induce chemotaxis of eosinophils and raise their cytosolic Ca2+ content ([Ca2+]i). The sources of this activity are the dense- and alpha-granules because inhibition of prostaglandin endoperoxide/thromboxane A2 formation and the platelet-activating factor receptor-antagonist WEB 2086 have no effect. Platelets from patients with Storage-Pool Deficiency show about 60% of the normal chemotactic activity with little effect on [Ca2+]i, whereas completely degranulated platelets fail to affect eosinophils. In concentrations secreted by the platelets, adenosine diphosphate (ADP), and platelet factor 4 have no effect, whereas adenosine triphosphate (ATP) induces a strong chemotactic response and increases [Ca2+]i. However, apart from ATP other modulating factors must be involved as platelet releasates induce more chemotaxis than ATP alone. Thus, platelets secrete factors that activate eosinophils and may contribute to inflammatory and allergic processes.
Growth of CdTe on Te Substrates by Solid-State Reaction (1979)

Cadmium-telluride was grown on Te substrates by heating (001) Te substrates with deposited Cd layers at low temperatures of 320–380°C in Cd vapour. The thickness of the CdTe layer increased with rise in annealing temperature and increase of annealing time and Cd vapour pressure, but was independent of the thickness of the Cd layer deposited. The reaction of Cd with Te was exothermic. The Cd vacancy concentration in CdTe near the interface between CdTe and Te was higher than elsewhere, and the diffusion of Cd atoms into the Te substrate was enhanced by the presence of this vacancy concentration gradient. A growth mechanism is proposed based on the experimental results, and the values of the thickness calculated from the model agree well with the experimental values.
Tuning-current splitting network for three-sectionDBR lasers (1994)

A simple current-splitting network for DBR-laser frequency tuning is proposed that distributes a single control current among two tuning sections and can adjust the current distribution without yielding impedance mismatching. The nonlinear characteristics of the tuning sections realise the non-proportional current splitting suitable for continuous tuning; 470 GHz (3.8 nm) tuning range is achieved.
