A Deep Learning Approach to VNF Resource Prediction using Correlation between VNFs (2019)

Software-Defined Networking (SDN) and Network Function Virtualization (NFV) greatly facilitate network service management. Specifically, these new network paradigms help manage the network environment dynamically and cost-efficiently. Virtual Network Function (VNF) and Service Function Chaining (SFC) are important aspects of the NFV environment. In terms of NFV management, resource demand of VNFs can be predicted at a future time to handle Quality of Service (QoS) and resource allocation problems efficiently. Hence, researchers study and build a management system where machine-learning-based predictions of VNF information are used to handle auto-scaling, deployment and migration of VNFs. In addition, in recent studies, these systems have involved SFC to obtain useful information, not just a lone VNF. However, not many of studies explain clearly how chaining dependency among VNFs in a SFC can be used to predict future resource demand of a VNF. In this paper, we introduce VNF resource prediction machine learning model that maximizes the benefits of using SFC. Then, we compare several machine learning models and analyze how SFC data can help predict resource usage patterns of VNFs. We also show benefits of Attention model to improve prediction accuracy and convergence time through experiments.
High resolution light and electron microscopic localization of tubulin with the IGS (immuno gold staining) method (1981)

Abstract A new, simple procedure is described for the production of 5 nm colloidal gold/secondary antibody reagents. Utilizing them with antitubulin shows 1) that they can be used for high resolution ultrastructural localization studies and 2) that this can be done with retention of satisfactory preservation of cell structure. The same, simple procedure can be used to prepare 20 nm colloidal gold/antibody reagents. These can be used for the high resolution light microscopic visualization of microtubules in interphase and mitotic cells. Colloidal gold labelled serum or monoclonal antibodies can be used in a new, general purpose immunocytochemical technique: the IGS (immuno gold staining) method.
Automated generation of materialized views in Oracle (2020)

Automated generation of a right set of materialized views is a challenging task. It is a highly desirable feature for autonomous databases. The selection of materialized views must be based on cost and verifiable in the actual database environment. This paper describes an automated system that generates, selects, verifies, and maintains materialized views in the Oracle RDBMS; it presents a novel technique, called the extended covering sub-expression algorithm, for the automated generation of materialized views. An extensive set of experiments is described that demonstrates the feasibility and efficiency of this approach. This system has been fully implemented and is going to be deployed on the Oracle Autonomous Database on the Cloud.

Improving body transmitted unvoiced speech with statistical voice conversion (2006)

The conversion method from Non-Audible Murmur (NAM) to ordinary speech based on the statistical voice conversion (NAM-toSpeech) has been proposed towards realization of “silent speech telephone.” Although NAM-to-Speech converts NAM to intelligible voices with similar quality to speech, there is still a large problem, i.e., difficulties of the F0 estimation from unvoiced speech. In order to avoid this problem, we propose a conversion method from NAM to whisper that is a familiar and intelligible unvoiced speech (NAM-to-Whisper). Moreover, we enhance NAM-to-Whisper so that multiple types of body-transmitted unvoiced speech such as NAM and Body Transmitted Whisper (BTW) are accepted as input voices. We evaluate the performance of the proposed conversion method. Experimental results demonstrate that 1) intelligibility and naturalness of NAM are significantly improved by NAM-toWhisper, 2) NAM-to-Whisper outperforms NAM-to-Speech, and 3) we can train a single conversion model successfully converting both NAM and BTW to the target voice. Index Terms: silent speech telephone, body transmitted unvoiced speech, voice conversion, F0 estimation, whisper
Heterogeneity of beta-type myosin isozymes in the human heart and regulational mechanisms in their expression. Immunohistochemical study using monoclonal antibodies. (1988)

To investigate the existence of heterogeneity of beta-type myosin isozymes (HC beta) in human hearts, immunohistochemical studies using monoclonal antibodies (MoAbs) raised against human ventricular myosin heavy chains were performed. Two types of MoAbs recognized some muscle fibers in the atrium, whereas both reacted with all ventricular muscle fibers. Since atrial muscle fibers reactive with each MoAb were found to be clearly different, the existence of two immunologically distinct HC beta (beta 1, and beta 2) was suggested in the atrium. By using affinity chromatography, two molecular variants of HC beta were isolated from the bovine atrium, and differences in the primary structure of beta 1 and beta 2 were confirmed by analysis of peptides produced by chymotryptic digestion. In pressure-overloaded human atria, myofibers containing beta 1 and/or beta 2 increased in accordance with decrement of myofibers containing alpha-type myosin isozyme (P less than 0.01). But they differed in expression during the developmental stage, since beta 2 did not exist in the early embryonic bovine heart, but beta 1 did. Thus, there are two distinct HC beta whose expression is regulated by at least two factors: pressure overload and developmental stage.
Picos, A Hardware Task-Dependence Manager for Task-Based Dataflow Programming Models (2017)

Task-based programming Task-based programming models such as OpenMP, Intel TBB and OmpSs are widely used to extract high level of parallelism of applications executed on multi-core and manycore platforms. These programming models allow applications to be expressed as a set of tasks with dependences to drive their execution at runtime. While managing these dependences for task with coarse granularity proves to be highly beneficial, it introduces noticeable overheads when targeting fine-grained tasks, diminishing the potential speedups or even introducing performance losses. To overcome this drawback, we propose a hardware/software co-design Picos that manages inter-task dependences efficiently. In this paper we describe the main ideas of our proposal and a prototype implementation. This prototype is integrated with a parallel task- based programming model and evaluated with real executions in Linux embedded system with two ARM Cortex-A9 and a FPGA. When compared with a software runtime, our solution results in more than 1.8x speedup and 40% of energy savings with only 2 threads.
Manipulation of receptor oligomerization as a strategy to inhibit signaling by TNF superfamily members (2014)

Signaling by receptor activator of nuclear factor κB (RANK) in response to its ligand RANKL, which is a member of the tumor necrosis factor (TNF) superfamily of cytokines, stimulates osteoclast formation and bone resorption. Thus, this ligand-receptor pair is a therapeutic target for various disorders, such as osteoporosis and metastasis of cancer to bone. RANKL exists as a physiological homotrimer, with each monomer recognizing a single molecule of RANK or the decoy receptor osteoprotegerin (OPG), which inhibits osteoclastogenesis. We engineered a RANKL protein in which all three monomers of RANKL were encoded as a single polypeptide chain, which enabled us to independently control receptor binding at each binding interface. To generate an effective RANK inhibitor, we used an unbiased forward genetic approach to identify mutations in RANKL that had a 500-fold increased affinity for RANK but had decreased affinity for the decoy receptor OPG. Incorporating mutations that blocked receptor binding into this high-affinity RANKL variant generated a mutant RANKL that completely inhibited wild-type RANKL-induced osteoclastogenesis in vitro and bone resorption in mice. Our approach may be generalized to enable the inhibition of other TNF receptor signaling systems, which are implicated in a wide range of pathological conditions.

Glycerol derivatives for diesel fuel reformulation (2005)

<div class="htmlview paragraph">Biofuels are an important means of progress to reduce greenhouse gases and local pollution and to diversify energy. For diesel engines, FAME (Fatty Acid Methyl Ester), coming from trans esterification of vegetable oils, have already shown their potential as fuel substitutes. Nevertheless, this trans esterification induces glycerol production as a co - product. At the same time, oxygenated compounds have been shown to have great potential for reducing diesel particulate emissions. So using glycerol as a basis to synthesize new oxygenated compounds, for diesel fuel formulation could be promising.</div> <div class="htmlview paragraph">This paper deals with the synthesis of oxygenated compounds coming from glycerol, such as acetals, ethers, or carbonates, and their evaluation as blending components in diesel fuel. The objective of this work is to evaluate their potential, in terms of pollutant emissions, with different engine technologies.</div> <div class="htmlview paragraph">Their impact on particulate emissions depends on the engine technology and the chemical structure of the glycerol derivatives.</div> <div class="htmlview paragraph">For the Euro II vehicle, the decrease in particulate emissions is up to 20% on NEDC cycle.</div> <div class="htmlview paragraph">Although the Euro III vehicle is less sensitive than the Euro II, with only 5% in volume of glycerol derivatives, up to 12% of particulate reduction is possible.</div> <div class="htmlview paragraph">The impact on NOx emissions is rather low especially for the Euro III vehicle.</div> <div class="htmlview paragraph">Tests with an HCCI engine have shown that some glycerol compounds could improve the running of HCCI engine.</div>
Stable Field Emitters for a Miniature X-ray Tube Using Carbon Nanotube Drop Drying on a Flat Metal Tip (2010)

Stable carbon nanotube (CNT) field emitters for a vacuum-sealed miniature X-ray tube have been fabricated. The field emitters with a uniform CNT coating are prepared by a simple drop drying of a CNT mixture solution that is composed of chemically modified multi-walled CNTs, silver nanoparticles, and isopropyl alcohol on flat tungsten tips. A highly thermal- and electrical-conductive silver layer strongly attaches CNTs to the tungsten tips. Consequently, the field emitters exhibit good electron emission stability: continuous electron emission of around 100 μA at 2.3 V/μm has stably lasted over 40 h even at non-high vacuum ambient (~10-3 Pa).
Efficient multilevel coding scheme for video transmission (1992)

A coding scheme comprising interframe DPCM, sub-band coding, and the discrete cosine transform is presented. The scheme has been expanded to include a multilevel video transmission which has resulted in a hybrid DPCM/DCT coding structure at its lowest level. This property is then used to transmit high quality video with full compatibility to existing hybrid based coding standards such as H.261 for videophone. In addition, for each level to be coded independently, a layer called the residual layer is generated at the lower level. Simulation results are presented for a two-level video transmission where the first and second levels are coded at the rates of 64kbit/s and 4Mbit/s, respectively

Improved delivery through biological membranes. 39. Brain-specific chemical delivery systems for .beta.-lactam antibiotics. In vitro and in vivo studies of some dihydropyridine and dihydroisoquinoline derivatives of benzylpenicillin in rats (1989)

Four chemical delivery systems (CDS's) based on a dihydropyridine----quaternary pyridinium salt redox system were used for the brain delivery of benzylpenicillin (BP). CDS's 5 and 9 are diesters of C1 and C2 diols in which one hydroxyl group is esterified by the benzylpenicillin-3-carboxylic group and the other by dihydrotrigonelline. CDS's 13a and 17 are benzylpenicillin esters of amino alcohols in which the amine group is acylated by dihydro-trigonelline (13a) or by 1,2-dihydro-2-methyl-4-isoquinolinecarboxylic acid (17). In vitro relative stability studies showed that both CDS's and quaternary pyridinium salts were quite unstable in rat and rabbit blood or brain but much more stable in dog or human blood. Kinetic studies performed in rat brain homogenate demonstrated the facile enzymatic oxidation of the CDS's to the corresponding quaternary salts. Hydrolysis of the CDS's and the quaternary salts resulted in the release of benzylpenicillin. In biological media CDS 13a also yielded a water addition product, the 6-hydroxy-1,4,5,6-tetrahydropyridine derivative. In vivo distribution studies were carried out in rats. After iv administration of equimolar doses of BP and CDS's, brain benzylpenicillin levels were found to be substantially higher and more prolonged in case of 5 and 9 than of BP itself. However, administration of 13a and 17 resulted in lower brain benzylpenicillin levels due to the water addition reaction and a nonspecific brain delivery, respectively. The remarkable increase of BP levels as well as the prolonged effect after the administration of 5 and 9 is a result of an improved penetration through the blood-brain barrier of the lipophilic CDS's and a "lock-in" effect of the corresponding quaternary salts generated in situ.
Electrical stimulation and hydration to optimise meat quality ( Conference Paper ) (2006)

This article discusses research that was conducted to optimise new electrical-stimulation technologies and to elucidate the effects of pre-slaughter dehydration of lambs. A change in lamb processing to a focus on eating quality has increased the uptake of new electrical technologies. Our research was aimed at understanding how carcase response to electrical stimulation is affected by genotype, pulse-width, current, and frequency and time of stimulation. Although seven post-dressing electrical stimulation systems have been installed in abattoirs across Australia and two prototype pre-dressing systems and an immobiliser have been installed at a major export abattoir, more installations are needed. An indicator of animal dehydration status was developed and used at two commercial abattoirs. This study showed that a large percentage of lambs are dehydrated at the time of slaughter, which represents a potential cost to industry $5 million annually. Although several compounds for prevention of pre-slaughter dehydration in lambs were tested, none were effective.
Biodegradable paper/polymerized vegetable oil mulches for tomato and pepper production (2006)

This project was undertaken to compare the efficacy of a biodegradable paper/cured vegetable oil mulch with newspaper/straw and bare soil for reducing weed growth and promoting vegetable yields. There were no significant differences in total tomato (<i>Lycopersicon esculentum</i>)<i> </i>or pepper (<i>Capsicum annum</i>)<i> </i>yields between the different mulch types. The coated paper and newspaper/straw mulches were effective in preventing weed growth around the plants while hand weeding was required for the bare soil plots. After 3 months, there was slight degradation (a few cracks, names are necessary to report factually on available data; however the USDA neither guarantees nor warrants the standard of the product, and the use of the name. USDA implies no approval of the product to the exclusion of others that may also be suitable. holes) of the coated paper mulches but not enough to allow noticeable weed penetration or detachment of the buried edge. Paper/cured oil mulch rolls appear to be a convenient and effective alternative to laborious hand weeding or spreading of newspaper and straw for vegetable gardening.
A New Model To Obtain Representative Field Relative Permeability for Reservoirs Produced Under Solution-Gas Drive (2005)

Summary Relative permeability curves (kr) control production and are of primary importance for any type of recovery process. In the case of production by displacement (waterflood or gasflood), the kr curves obtained in the laboratory can be used in numerical simulators to predict hydrocarbon recovery (after upscaling to account for heterogeneity). In the case of reservoirs produced under solution-gas drive (depressurized field, foamy oils), the experiments conducted in the laboratory depend on the depletion rate and cannot be used directly for reservoir simulations. We have developed a novel approach for calculating representative field relative permeabilities. This new method is based on a physical model that takes into account the various mechanisms of the process: bubble nucleation (pre-existing bubbles model), phase transfer (volumetric transfer function), and gas displacement (bubble flow). In our model, we have identified a few "invariant" parameters that are not sensitive to depletion rate and are specific to the rock/fluid system (mainly the pre-existing bubble-size distribution and a proportionality coefficient relating gas and oil velocity for the dispersed-phase regime). These invariant parameters are determined by history matching one experiment at a given depletion rate. The calibrated model is then used to generate synthetic data at any depletion rate, especially at very low depletion rates representative of the reservoir conditions. Relative permeabilities are derived from these "numerical" experiments in the same way as they are from real experiments. The calculated kr is finally used in commercial reservoir simulators. We have tested our model by using several series of published experiments with light and heavy oils. After adjusting the invariant parameters on one or two experiments, we are able to predict other experiments performed at different depletion rates with very good accuracy. Finally, we present an example of determination of relative permeabilities at reservoir depletion rates.
Extraction of Uranium(IV) from Phosphoric Acid by Kerosene Solution of Mono-(2-ethylhexyl) Phosphoric Acid and Neutral Organophosphorus Synergists (1981)

Abstract The extraction of uranium(IV) from phosphoric acid by mono-(2-ethylhexyl) phosphoric acid in kerosene has been investigated. The effects of extractant concentration, hydrogen ion concentration, temperature, and the synergistic effect of trioctyl phosphine oxide and dibutyl butyl phosphonate on this extraction system have been examined. Based on the extractant dependency and the acid dependency, an ion-exchange mechanism was generally observed and the extracted species were of the type, UH8n-4X4n , UH8n-4X4n , · TOPO, and UH8n-4X4n , · DBBP. The temperature effect for the extraction reaction has also been studied.
Hydrogen Silsesquioxane:  A Molecular Precursor for Nanocrystalline Si−SiO<sub>2</sub> Composites and Freestanding Hydride-Surface-Terminated Silicon Nanoparticles (2006)

We report the bulk preparation of nanocrystalline Si−SiO2 (nc-Si/SiO2) composites via straightforward reductive thermal annealing of a well-defined molecular precursor, hydrogen silsesquioxane. The presented method affords quantitative yields of composite powders in large quantities. Freestanding, hydride-surface-terminated silicon nanocrystals that photoluminesce throughout the visible spectrum are readily liberated from nc-Si/SiO2 composite powders upon etching in ethanol−water solutions of hydrofluoric acid. Composites and freestanding particles were characterized using transmission electron microscopy (TEM), selected area electron diffraction (SAED), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), photoluminescence (PL) spectroscopy, Fourier transform infrared spectroscopy (FT−IR), and thermogravimetric analysis (TGA).
