Seamless Migration of Virtual Machines across Networks (2013)

Current technologies that support live migration require that the virtual machine (VM) retain its IP network address. As a consequence, VM migration is oftentimes restricted to movement within an IP subnet or entails interrupted network connectivity to allow the VM to migrate. Thus, migrating VMs beyond subnets becomes a significant challenge for the purposes of load balancing, moving computation close to data sources, or connectivity recovery during natural disasters. Conventional approaches use tunneling, routing, and layer-2 expansion methods to extend the network to geographically disparate locations, thereby transforming the problem of migration between subnets to migration within a subnet. These approaches, however, increase complexity and involve considerable human involvement. The contribution of our paper is to address the aforementioned shortcomings by enabling VM migration across subnets and doing so with uninterrupted network connectivity. We make the case that decoupling IP addresses from the notion of transport endpoints is the key to solving a host of problems, including seamless VM migration and mobility. We demonstrate that VMs can be migrated seamlessly between different subnets - without losing network state - by presenting a backward-compatible prototype implementation and a case study.
Physiologic and Electrocardiographic Changes Occurring in Broilers Reared at Simulated High Altitude (1995)

An experiment was conducted to determine whether differences in the electrocardiograms (EKGs) of broilers reared at simulated high altitude from the day of hatch can be used to predict which birds are developing ascites. In three replicate experiments, conducted with 100 broilers per replicate, birds were reared at a simulated altitude of 3000 meters or at ambient atmospheric pressure. Lead I, II, and III EKGs were obtained from all birds on days 0, 14, 28, and 42. No consistent significant differences were seen on day 0 in the amplitude of the R or S wave or total amplitude of the QRS complex when broilers that developed ascites while being reared at simulated high altitude were compared with unaffected birds reared at simulated high altitude and with birds reared at ambient atmospheric pressure. On days 14 and 28, the average amplitude of the S wave and the total amplitude of the QRS complex were significantly higher in the ascites group than in the two other groups. Packed cell volumes were significantly higher in birds reared at simulated high altitude at all sampling days (days 14, 28, and 42) than in those reared at ambient atmospheric pressure, and they were significantly higher in the ascites group on day 28 than in the two other groups. Birds in the ascites group weighed significantly less than the two other groups by day 14, and this trend persisted.
Mixed binary multiplication of optical signals by convolution in an inhomogeneously broadened absorber (1986)

We have employed the recently developed technique of real-time optical waveform convolution in inhomogeneously broadened absorbers [ Appl. Phys. Lett.45, 714 ( 1984)] to perform mixed binary multiplication of digital optical signals. We demonstrate that an output signal representing the mixed binary product of up to three numbers encoded into discrete input signals can be generated in a single convolution cycle. We have studied the effect of material relaxation on output signal shapes and intensities. We find that mixed binary product signals up to ∼0.5% as intense as the input signals can be expected in weakly relaxing materials. This method of all-optical multiplication may be useful in high-speed applications, since its bit rate is limited fundamentally only by the inhomogeneous absorption bandwidth of the material used.
Study on the Start-Stop System Control Strategy under Different Driving Cycle (2018)

Ineffective idle stop of the engine and frequent start-stop of vehicles is the main problem that the vehicle start-stop system is facing and the changing driving cycles are the primary cause of this problem. As a result, the purpose of this paper is to improve the overall fuel saving effect of the start-stop system by optimizing the control strategy under different driving cycles. This paper firstly analyzed the cause of ineffective idle stop and put forward two control parameters (delay the action time and set speed threshold) which were used to avoid the ineffective idle stop and frequent start-stop problem. Then selected four typical driving cycles and proposed the multi-mode control strategy which can improve the overall fuel saving effect, followed by obtaining the optimal control parameters respectively when minimize the idle time was taken as the optimizing objective and nonlinear constrained optimization method was adopted. The simulation result shows that this method can effectively improve the overall fuel saving effect of the start-stop system.
An environment‐friendly thermal insulation material from cellulose and plasma modification (2013)

ABSTRACT Cellulose aerogels were prepared by combining the NaOH/thiourea/H 2 O solvent system and the freeze‐drying technology. Hydrophobic aerogels were obtained with the cold plasma modification technology. The results showed that cellulose aerogel had good heat insulation performance, while the main factors affecting thermal conductivity were density and porosity. Thermal conductivity decreased with the decrease of density and the increase of porosity. It could be as low as 0.029 W/(m K). Cellulose aerogel adsorbed moisture easily. The moisture adsorption had a significant influence on the heat insulation performance of aerogel. After conducting hydrophobic modification using CCl 4 as plasma, cellulose aerogel was changed from hydrophilic to hydrophobic and water contact angle was as high as 102°. Hydrophobic modification did not affect the heat insulation performance of aerogel. This work provided a foundation for the possibility of applying cellulose aerogels in the insulating material field. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 3652–3658, 2013
The synthesis and characterisation of hetero-bimetallic sulfonate bridged coordination polymers of the type M<sup>II</sup>Sn<sup>IV</sup>(SO<sub>3</sub>X)<sub>6</sub> with X = F or CF<sub>3</sub> (1987)

The synthesis of a series of hetero-bimetallic fluorosulfate bridged coordination polymers of the type M(II)Sn(SO 3 F) 6 , with M(II) = Mn, Fe, Co, Ni, or Cu, by interaction of the metal bisfluorosulfate with the strong fluorosulfate acceptor Sn(SO 3 F) 4 in fluorosulfuric acid is described. Subsequent solvolysis of either stoichiometric 1:1 mixtures of M(SO 3 F) 2 and Sn(SO 3 F) 4 or the bimetallic polymer M(II)Sn(IV)(SO 3 F) 6 in an excess of trifluoromethyl sulfuric acid affords the corresponding SO 3 CF 3 -bridged polymers of the composition M(II)Sn(SO 3 CF 3 ) 6 with M(II) = Mn, Fe, Co, Ni, or Cu. The new compounds are characterized by infrared and 119 Sn Mössbauer spectroscopy.

Central carbon metabolism of<i>Saccharomyces cerevisiae</i>in anaerobic, oxygen-limited and fully aerobic steady-state conditions and following a shift to anaerobic conditions (2007)

Saccharomyces cerevisiae CEN.PK113-1A was grown in glucose-limited chemostat culture with 0%, 0.5%, 1.0%, 2.8% or 20.9% O2 in the inlet gas (D=0.10 h(-1), pH 5, 30 degrees C) to determine the effects of oxygen on 17 metabolites and 69 genes related to central carbon metabolism. The concentrations of tricarboxylic acid cycle (TCA) metabolites and all glycolytic metabolites except 2-phosphoglycerate+3-phosphoglycerate and phosphoenolpyruvate were higher in anaerobic than in fully aerobic conditions. Provision of only 0.5-1% O2 reduced the concentrations of most metabolites, as compared with anaerobic conditions. Transcription of most genes analyzed was reduced in 0%, 0.5% or 1.0% O2 relative to cells grown in 2.8% or 20.9% O2. Ethanol production was observed with 2.8% or less O2. After steady-state analysis in defined oxygen concentrations, the conditions were switched from aerobic to anaerobic. Metabolite and transcript levels were monitored for up to 96 h after the transition, and this showed that more than 30 h was required for the cells to fully adapt to anaerobiosis. Levels of metabolites of upper glycolysis and the TCA cycle increased following the transition to anaerobic conditions, whereas those of metabolites of lower glycolysis generally decreased. Gene regulation was more complex, with some genes showing transient upregulation or downregulation during the adaptation to anaerobic conditions.
Subscriber-Loop Digital Transmission Using Opto-Electronic Transmitters and Receivers (1979)

The efficiencies of different methods for subscriber-loop digital transmission are compared, using as a criterion the cost per bit/second per kilometer of wire, denoted "CSP". Approaches to reduction of CSP are suggested, in particular the use of opto-electronic transmitters and receivers in a differential connection, resulting in a relatively noise-immune subscriber line. A graphic method for the analysis of opto-electronic digital transmission lines is described.
Three-dimensional imaging of single nanotube molecule endocytosis on plasmonic substrates (2012)

Investigating the cellular internalization pathways of single molecules or single nano objects is important to understanding cell-matter interactions, and to applications in drug delivery and discovery. Imaging and tracking the motion of single molecules on cell plasma membranes require high spatial resolution in three dimensions. Fluorescence imaging along the axial dimension with nanometre resolution has been highly challenging, but critical to revealing displacements in transmembrane events. Here, utilizing a plasmonic ruler based on the sensitive distance dependence of near-infrared fluorescence enhancement of carbon nanotubes on a gold plasmonic substrate, we probe ~10 nm scale transmembrane displacements through changes in nanotube fluorescence intensity, enabling observations of single nanotube endocytosis in three dimensions. Cellular uptake and transmembrane displacements show clear dependences to temperature and clathrin assembly on cell membrane, suggesting that the cellular entry mechanism for a nanotube molecule is via clathrin-dependent endocytosis through the formation of clathrin-coated pits on the cell membrane.
Microbiology of the Gastrointestinal Tract (1996)

The intestinal microflora is a complex ecosystem containing over 400 bacterial species. Anaerobes outnumber facultative anaerobes. The flora is sparse in the stomach and upper intestine, but luxuriant in the lower bowel. Bacteria occur both in the lumen and attached to the mucosa, but do not normally penetrate the bowel wall .
A YAC contig encompassing the chromosome 7p locus for autosomal dominant retinitis pigmentosa (1994)

Retinitis pigmentosa is an inherited retinal degeneration characterized by night blindness and loss of peripheral vision, often leading to complete blindness. The autosomal dominant form (adRP) maps to at least six different loci, including the rhodopsin and peripherin/Rds genes and four loci identified only by linkage analysis on chromosomes 7p, 7q, 8cen and 19q. The 7p locus was reported by this laboratory in a large English family, with a lod score of 16.5. Several new genetic markers have been tested in the family and this locus has now been refined to an interval of approximately 1 cM between markers D7S795 and D7S484 in the 7p13-15 region. In order to clone the gene for adRP, we have used microsatellites and STSs from the region to identify over 80 YACs, from four different libraries, which map to this interval. End clones from key YACs were isolated for the generation of additional STSs. Eleven microsatellite markers between D7S435 (distal) and D7S484 (proximal) have been ordered by a combination of both physical and genetic mapping. In this way we have now obtained a YAC contig spanning approximately 3 megabases of chromosome 7p within which the adRP gene must lie. One gene (aquaporin) and onemore » chromosome 7 brain EST have been placed on the contig but both map distal to the region of interest. Sixteen other ESTs and three further known 7p genes mapping in the region have been excluded. We are now attempting to build a cosmid contig in the defined interval and identify further expressed sequences from both YACs and cosmids to test as candidates for the adRP gene.« less
Dual active bridge buck-boost converter (2009)

A novel isolated bidirectional DC/DC converter suitable for high power applications is proposed. The proposed converter has bidirectional power flow capability with low device ratings for a wide source voltage range. The converter is controlled by varying the duty cycle and phase of the firing pulses, to achieve power flows in both directions and controlled current stresses, resulting in low total device rating (TDR) for a wide source voltage range. The proposed converter can scale to high power and uses system parasitics effectively. As a proof of concept, simulation results and comparison of TDR with conventional solutions based on analytical derivations are presented in a 100 kW level. Design considerations in building DAB <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> converter in a 100 kW level are presented.
Structure of Si/SiO2 thin multilayers sputtered in argon–hydrogen mixtures (1989)

A technique is described for preparing Si/SiO2 thin multilayers by performing sputtering from two independent sources in argon–hydrogen mixtures. Structural studies carried out by x-ray diffraction and Auger electron spectroscopy indicate a well-defined multilayer structure. The x-ray reflection peaks of the Si/SiO2 multilayer structure are found to intensify as a result of (i) inclusion of hydrogen in the sputtering gas and (ii) lowering of the sputtering pressure. Studies of the infrared spectra reveal that samples produced by sputtering in argon–hydrogen mixtures have absorption bands at ∼880 and 630 cm−1.
Probing DNA triple helix structure by chemical ligation (1991)

A series of oligomeric double and triple helical DNAs with irregular sequences of homopurine and homopyrimidine strands were prepared. DNA triplexes were identified by CD spectroscopy and thermal denaturation profiles (biphasic helix-coil transition). Condensation of oligonucleotides on single and double-stranded DNA templates was performed using water-soluble carbodiimide, phosphodiester and pyrophosphate internucleotide bonds being newly formed. Such chemical ligation proved to be a sensitive monitor of changes in the sugar-phosphate backbone resulting from conversion of double to triple helix and of third-strand binding.
Studies on the experimental variables effects on rhodium catalyzed hydroformylation of unsaturated fatty esters and comparison of [RhH(CO)(PPh3)3] and [RhCl3.3H2O] as starting catalytic precursors (2005)

Hydroformylation experiments were performed with technical-grade methyl oleate (MO) and soybean oil (SO) using [RhH(CO)(PPh3)3] and [RhCl3.3H2O] (double bond/Rh = 745) as catalyst precursors modified or not by triphenylphosphine. [RhH(CO)(PPh3)3] shows 100% conversion and 80-91% selectivity to aldehydes in only 4h for both substrates under mild conditions (100 °C, 40 bar, CO/H2 = 2:1, ligand/Rh = 10:1). Despite the rapid isomerisation of the soybean oil, producing trans isomers and conjugated dienes, no effects were observed on its further conversion to aldehydes. The reaction of soybean oil conducted with pure [RhCl3.3H2O] produced only conjugated dienes, and when this precursor was modified with triphenylphosphine (ligand/Rh = 10:1) no reaction was observed at all. Curiously, yellow crystals corresponding to the complex [Rh(Cl)(CO)(PPh3)2] were quantitatively isolated at the end of the reaction .
Solar Photothermochemical Reaction and Supercritical CO<sub>2</sub>Work up for a Fully Green Process of Preparation of Pure<i>p</i>-Nitrobenzyl Bromide (2013)

It has been reported by us recently that p-nitrobenzyl bromide (PNBBr) can be synthesized from p-nitrotoluene (PNT) in high isolated yield with respect to available bromine in 2:1 Br(-)-BrO3(-) employed as brominating reagent. The reaction was conducted in ethylene dichloride (EDC) and the substrate was taken in excess to suppress dibromo impurity formation. The product was "cold crystallized" from the reaction mass and the mother liquor was recycled in the subsequent batch thereby eliminating organic discharge. The present work attempts to further advance the synthesis of this commercially important molecule employed in protection-deprotection strategies. Herein its successful synthesis employing neat substrate and solar radiation as the sole energy source to drive this photothermochemical reaction is reported. Further, 100% pure PNBBr could be isolated from the solid reaction mass in 87% yield by leaching out the excess substrate through supercritical CO2 (Sc-CO2) extraction. The reaction was therefore accomplished cleanly in all respects and with low carbon footprint.
High Voltage Pulsar For 184-inch Cyclotron Electric Deflector (1948)

This paper describes a high voltage pulse generator developed to deflect the beam of the 184-inch cyclotron at Berkeley, California. The apparatus develops a deflecting potential of 200 kilovolts that rises from 10% to 90% of peak value in 0.1 microseconds. The unit employs two similar 100 kilovolt water cooled pulse transformers connected symmetrically about ground to the electric deflector bars. Water-cooled General Electric pulse capacitors are discharged through the two turn primary windings of the pulse transformers by triggering a battery of 16 paralleled Kuthe 5022 hydrogen thyratrons. Output voltages are developed across the 17 turn secondary winding of the pulse transformer. The transformer is mounted in an oil filled lucite case that provides both insulation and compact design.
The future of cable TV (1969)

The problem of polluting our skies extends beyond man's senses; our ether is becoming ensnarled with electromagnetic emanations. The situation has become critical and, if our technology is not to mire in a morass of radio signals, something will have to be done to quiet the confusion. Some systems by nature of their operation must pick their inputs from the airwaves. But there are a host of others that can do just as well-if not better - linked directly to a transmitter. Thus, many receivers now operating, and envisaged for future operation, will be phased to cable operation.
Generating content presentation according to purpose (2009)

Programming graphical user interfaces is hard and expensive, while automatic generation is still quite challenging. One of the issues involved in automatic generation is the presentation of content from the domain of discourse according to its purpose in the current context of the human-machine dialogue. For example, it makes a difference whether the same piece of information is to be presented in the context of asking a user something, or simply for the purpose of informing. We address this issue through generating content presentation specifically according to the type of communicative act, that indicates the purpose. In the course of transforming a high-level discourse model to a structural user interface model, we apply specific model-transformation rules to content types, depending on the type of communicative act they are referred from. This results in automatically generated user interfaces with content presentations according to purpose.
Temperature modulation of the visible and near infrared absorption and scattering coefficients of human skin (2003)

We determine temperature effect on the absorption and reduced scattering coefficients (mu(a) and mu(s)(')) of human forearm skin. Optical and thermal simulation data suggest that mu( a) and mu(s)(') are determined within a temperature-controlled depth of approximately 2 mm. Cutaneous mu(s)(') change linearly with temperature. Change in mu(a) was complex and irreversible above body normal temperatures. Light penetration depth (delta) in skin increased on cooling, with considerable person-to-person variations. We attribute the effect of temperature on mu(s)(') to change in refractive index mismatch, and its effect on mu(a) to perfusion changes. The reversible temperature effect on mu (s)(' ) was maintained during more than 90 min. contact between skin and the measuring probe, where temperature was modulated between 38 and 22 degrees C for multiple cycles While temperature modulated mu(s)(' ) instantaneously and reversibly, mu(a) exhibited slower response time and consistent drift. There was a statistically significant upward drift in mu(a) and a mostly downward drift in mu( s)(') over the contact period. The drift in temperature-induced fractional change in mu(s)(') was less statistically significant than the drift in mu(s)('). Deltamu( s)(') values determined under temperature modulation conditions may have less nonspecific drift than mu(s)(') which may have significance for noninvasive determination of analytes in human tissue.
Masked Autoregressive Flow for Density Estimation (2017)

Autoregressive models are among the best performing neural density estimators. We describe an approach for increasing the flexibility of an autoregressive model, based on modelling the random numbers that the model uses internally when generating data. By constructing a stack of autoregressive models, each modelling the random numbers of the next model in the stack, we obtain a type of normalizing flow suitable for density estimation, which we call Masked Autoregressive Flow. This type of flow is closely related to Inverse Autoregressive Flow and is a generalization of Real NVP. Masked Autoregressive Flow achieves state-of-the-art performance in a range of general-purpose density estimation tasks.
