SDN enhanced ethernet VPN for data center interconnect (2017)

Ethernet Virtual Private Network (EVPN) is an emerging technology that addresses the networking challenges presented by geo-distributed Data Centers (DCs). One of the major advantages of EVPN over legacy layer 2 VPN solutions is providing All-Active (A-A) mode of operation so that the traffic can truly be multi-homed on Provider Edge (PE) routers. However, A-A mode of operation introduces new challenges. In the case where the Customer Edge (CE) router is multi-homed to one or more PE routers, it is necessary that only one of the PE routers should forward Broadcast, Unknown unicast, and Multicast (BUM) traffic into the DC. The PE router that assumes the primary role for forwarding BUM traffic to the CE device is called the Designated Forwarder (DF). The proposed solution to select the DF in the EVPN standard is based on a distributed algorithm which has a number of drawbacks such as unfairness and intermittent behavior. In this paper, we introduce a Software-Defined Networking (SDN) based architecture for EVPN support, where the SDN controller interacts with EVPN control plane. We demonstrate how our solution mitigates existing problems for DF selection which leads to improved EVPN performance.

Extended-range interferometry using a coherence-tuned, synthesised dual-wavelength technique with multimode fibre links (1988)

We describe in the letter a technique for making extended-range interferometric measurements with a coherence multiplexed system by means of a variation on the dual-wavelength technique. The interferometer is illuminated with a single source and the two wavelengths are synthesised at the output by means of an interference filter.
Uncertainty Based Detection and Relabeling of Noisy Image Labels (2019)

Deep neural networks (DNNs) are powerful tools in computer vision tasks. However, in many realistic scenarios label noise is prevalent in the training images, and overfitting to these noisy labels can significantly harm the generalization performance of DNNs. We propose a novel technique to identify data with noisy labels based on the different distributions of the predictive uncertainties from a DNN over the clean and noisy data. Additionally, the behavior of the uncertainty over the course of training helps to identify the network weights which best can be used to relabel the noisy labels. Data with noisy labels can therefore be cleaned in an iterative process. Our proposed method can be easily implemented, and shows promising performance on the task of noisy label detection on CIFAR-10 and CIFAR-100.
A New Synthesis Route for MWW Analogues Using Octyltrimethylammonium Cations as Structure-directing Agents under Alkali-free Conditions (2007)

Abstract Crystalline zeolites with the MWW topology are readily synthesized under hydrothermal conditions using long-chain quaternary ammonium cation like octyltrimethylammonium from high silica gels free of alkali metal ions, which implies a new route for preparing MWW-type metallosilicates.
Assessment (2004)

Imagine a clinician prescribing an antihypertensive medication without first checking and subsequently monitoring the patient’s blood pressure after he or she had started taking that medication. Few people would argue the inappropriateness of such a scenario. Paradoxically, it is more common than not that an analgesic is prescribed without a formal assessment of pain status. This clinically common practice of inadequate pain assessment is responsible for much of the inadequacy of pain management (1).
Wetting and Capillary Flow of Surfactant Solutions and Inks (2003)

This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. In the wetting experiments, water, alcohols, aqueous surfactant solutions and commercial ink-jet inks were used as test liquids, and a number of substrates, including silicate glass, hydrophobised silica, gold-alkanethiolate surfaces with controlled hydrophobicity and several different types of paper were examined with respect to their wettability. The primary goal of these studies was to investigate the dynamic effects of surfactant adsorption and surface tension relaxation on the spreading and capillary flow. Key factors, such as surface chemistry and topography of the substrates and physicochemical properties of the wetting liquids, which have been shown to control the spreading and absorption dynamics, have been identified, assessed and rationalized in the framework of the existing or newly developed theoretical models. The drop spreading and capillary rise experiments point out that the spreading process can be divided into at least two different spreading regimes, dominated by different mechanisms and force contributions. In the first regime, occurring immediately after the drop impact, the inertia forces play a significant role together with the surface forces and gravity. The second regime is characterised by quasi-steady flow. The rate-determining step in this regime is the diffusion transport of surfactant from the bulk to the depleted liquid-vapour interface. This regime is often dominating the overall spreading process of surfactant solutions. The diffusion limitation is for instance mirrored by the fact that the rate of spreading decreases with decreasing critical micelle concentration (cmc) of the surfactant. In the case of hydrophobic substrates, the origin of the effect is the slower diffusion of micelles compared to monomers; sometimes combined with slow micellar dissociation and barriers for direct micellar adsorption. Some of these observed phenomena are also reflected in the results of the more practical studies performed, involving e.g. inks and paper substrates. Further research is required in order to get a more complete picture although this thesis work highlights some central points with respect to paper sizing (hydrophobising) efficiency and ink spreading.
Dual-regulator dual-decoding-trimmer DRAM voltage limiter for burn-in test (1991)

The authors present a dynamic RAM (DRAM) voltage limiter with a burn-in test mode. It features a dual-regulator dual-trimmer scheme that provides a precise stress voltage in a burn-in test while maintaining a constant limited voltage under normal operation. A regulator is used to preserve a constant difference between the internal burn-in voltage and the supply voltage. Two sets of trimmers reduce the voltage deviations of both the burn-in and normal-operation voltages within +or-0.13 V. The circuits are implemented in a 16-Mb CMOS DRAM. A burn-in voltage regulated to +or-50 mV at an ambient temperature up to 120 degrees C is obtained simply by elevating the supply voltage to 8 V as in conventional burn-in procedures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Color Management for VR Production (2018)

Virtual reality offers a new way of telling stories and engaging audiences. To create appealing content for this new imaging modality, content production and post-production workflows need to be adapted or completely rethought. One key aspect for ensuring image quality and preservation of the director's intent throughout the production workflow is color management. In this paper, we review color managed workflows for (post) production and explore the challenges that arise for ensuring color accuracy in VR. We focus on the display end of the imaging pipeline, presenting a workflow for characterizing and calibrating VR devices. Our workflow is evaluated on several key VR devices, allowing us to compare their display characteristics and calibration quality.
Model of a single mode energy harvester and properties for optimal power generation (2008)

The process of acquiring the energy surrounding a system and converting it into usable electrical energy is termed power harvesting. In the last few years, the field of power harvesting has experienced significant growth due to the ever increasing desire to produce portable and wireless electronics with extended life. Current portable and wireless devices must be designed to include electrochemical batteries as the power source. The use of batteries can be troublesome due to their finite energy supply, which necessitates their periodic replacement. In the case of wireless sensors that are to be placed in remote locations, the sensor must be easily accessible or of disposable nature to allow the device to function over extended periods of time. Energy scavenging devices are designed to capture the ambient energy surrounding the electronics and covert it into usable electrical energy. The concept of power harvesting works towards developing self-powered devices that do not require replaceable power supplies. The development of energy harvesting systems is greatly facilitated by an accurate model to assist in the design of the system. This paper will describe a theoretical model of a piezoelectric based energy harvesting system that is simple to apply yet provides an accurate prediction of the power generated around a single mode of vibration. Furthermore, this model will allow optimization of system parameters to be studied such that maximal performance can be achieved. Using this model an expression for the optimal resistance and a parameter describing the energy harvesting efficiency will be presented and evaluated through numerical simulations. The second part of this paper will present an experimental validation of the model and optimal parameters.
Use of clipping in sigma-delta modulators (1994)

High-resolution conversion processes utilising sigma-delta modulation (SDM) with practical sampling rates and single-bit quantisers require high-order loop filters. Third- and higher-order systems are particularly prone to instability when the input signal approaches full-scale (set by the quantiser output voltage), and such overload instability results in very low signal-to-noise ratios (SNR) observed at the modulator output. This paper shows by simulation how this type of instability in a fourth-order coder can be avoided by placing clippers at loop-filter integrator outputs, and how optimal choice of clipper levels can increase the SNR observed when the modulator is in overload, from less than 0 dB without clippers to 40 dB->80 dB. Results generated using clippers where integrator outputs are reset are compared with those of saturating clippers. Other techniques for avoiding overload instability, such as adaptive loop filters, are also considered.<

Rat β casein cDNA: sequence analysis and evolutionary comparisons (1982)

The complete sequence of a 1072 nucleotide rat beta-casein cDNA insertion in the hybrid plasmid pC beta 23 has been determined. Primer extension was employed to determine the sequence of an additional 82 5'-terminal nucleotides in beta-casein mRNA. Rat beta-casein mRNA consists of a 696 nucleotide coding region, flanked by 52 nucleotide 5' and 406 nucleotide 3' noncoding regions, including a 40 nucleotide poly(A) tail. The derived 216 amino acid sequence of rat beta-casein was compared to the previously determined sequences of beta-caseins from several other species. Approximately 38% of the amino acids have been conserved among the rat, ovine, bovine and human sequences and these conserved amino acids occurred in clusters throughout the protein. One such cluster containing the majority of the potential casein phosphorylation sites was located near the amino terminus. Contrary to the considerable divergence observed for the processed beta-casein, 14 of 15 amino acids in the signal peptide sequence of the precasein were identical between the rat and ovine caseins.

Synthesis and Optical Properties of Organic-Inorganic Hybrid Mesoporous Materials with Naphthalene Bridging Groups (2013)

Ordered naphthalene-bridged hybrid periodic mesoporous organosilicas (PMOs) were synthesized by co-condensation of 2,7-bis(3-triethoxysilylpropylaminocarbonyloxy) naphthalene (NIS) and tetraethoxy orthosilane (TEOS) using cationic trimeric surfactant [C10H21N+ (CH 3)2 (CH2)2N +(CH3) (C10H21)(CH2)2N+ (CH3)2C10H21 ] · 3Br as a structure-directing agent.The resulting samples were characterized by powder X-ray diffraction,high resolution transmission electron microscopy,nitrogen adsorption-desorption,and differential scanning calorimetry/thermogravimetric analysis.Ordered mesoporous hybrid materials with a crystal-like pore wall formed when the molar ratio of NIS to the sum of NIS and TEOS was 40%.When this value is below or above 40%,ordered mesoporous hybrid materials with amorphous phase in the pore walls,and nonporous hybrid materials are obtained,respectively.As the number of naphthyl groups in the pore walls increases,the thermal stability of the hybrid materials is enhanced through the strong π-π interactions between organic groups.Because of the fluorescent naphthyl groups in the silica framework,the PMOs exhibit optical behavior consistent with excimer formation.Absorption spectra of the PMOs show blue shifts compared with that of the precursor (NIS),suggesting the formation of aggregates in the pore walls of the hybrid materials.As the molar ratio of NIS to the sum of NIS and TEOS increases,the fluorescence quantum yield of the PMOs decreases through fluorescence quenching caused by aggregation of naphthyl groups.
Efficient Scalable Computing through Flexible Applications and Adaptive Workloads (2017)

In this paper we introduce a methodology for dynamic job reconfiguration driven by the programming model runtime in collaboration with the global resource manager. We improve the system throughput by exploiting malleability techniques (in terms of number of MPI ranks) through the reallocation of resources assigned to a job during its execution. In our proposal, the OmpSs runtime reconfigures the number of MPI ranks during the execution of an application in cooperation with the Slurm workload manager. In addition, we take advantage of OmpSs offload semantics to allow application developers deal with data redistribution. By combining these elements a job is able to expand itself in order to exploit idle nodes or be shrunk if other queued jobs could be initiated. This novel approach adapts the system workload in order to increase the throughput as well as make a smarter use of the underlying resources. Our experiments demonstrate that this approach can reduce the total execution time of a practical workload by more than 40% while reducing the amount of resources by 30%.
Biofilm Growth and Hydraulic Performance (1980)

An experimental investigation of the deleterious effect of microbial slime layers on the hydraulic performance of water conduits is presented. The underlying mechanisms that lead to an increase of frictional losses in the conduit are explored and their relative importance is discussed. It is shown that although the slime layer is viscoelastic and filamentous, its effect on frictional resistance can be adequately represented through an increase in rigid equivalent sand roughness of the conduit wall.
ENERGY‐DEPENDENT PROCESSES IN CHARA CORALLINA: ABSENCE OF LIGHT STIMULATION WHEN ONLY PHOTO‐SYSTEM ONE IS OPERATIVE (1974)

S ummary Light‐stimulated active chloride influx in Chara corallina , like that in other giant algal cells, requires the operation of photo‐system two of photosynthesis. Active phosphate influx and glucose influx also require photo‐system two for light‐stimulation, and are not stimulated by light under anaerobic conditions. This contrasts with the situation in Nitella and Hydrodictyon where influx of phosphate and glucose can be supported by photo‐system one, i.e. by cyclic photophosphorylation alone. None of the other metabolic processes in Chara tested in this work (acetate uptake and oxidation, starch synthesis, and passive Rb + influx), or described elsewhere in the literature, are light‐stimulated when photo‐system two is inoperative. Possible explanations of this apparent inability of cyclic photophosphorylation to act as a source of metabolic energy in Chara are suggested. Their significance is discussed in relation to hypotheses of the light reactions of photosynthesis and mechanisms of light‐dependent solute transport.
Genome-Wide Functional Synergy between Amplified and Mutated Genes in Human Breast Cancer (2008)

A single cancer cell contains large numbers of genetic alterations that in combination create the malignant phenotype. However, whether amplified and mutated genes form functional and physical interaction networks that could explain the selection for cells with combined alterations is unknown. To investigate this issue, we characterized copy number alterations in 191 breast tumors using dense single nucleotide polymorphism arrays and identified 1,747 genes with copy number gain organized into 30 amplicons. Amplicons were distributed unequally throughout the genome. Each amplicon had distinct enrichment pattern in pathways, networks, and molecular functions, but genes within individual amplicons did not form coherent functional units. Genes in amplicons included all major tumorigenic pathways and were highly enriched in breast cancer-causative genes. In contrast, 1,188 genes with somatic mutations in breast cancer were distributed randomly over the genome, did not represent a functionally cohesive gene set, and were relatively less enriched in breast cancer marker genes. Mutated and gained genes did not show statistically significant overlap but were highly synergistic in populating key tumorigenic pathways including transforming growth factor beta, WNT, fibroblast growth factor, and PIP3 signaling. In general, mutated genes were more frequently upstream of gained genes in transcription regulation signaling than vice versa, suggesting that mutated genes are mainly regulators, whereas gained genes are mostly regulated. ESR1 was the major transcription factor regulating amplified but not mutated genes. Our results support the hypothesis that multiple genetic events, including copy number gains and somatic mutations, are necessary for establishing the malignant cell phenotype.
Pressure evolution of the low-temperature crystal structure and bonding of the superconductor FeSe<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mrow><mml:mo>(</mml:mo><mml:mrow><mml:msub><mml:mi>T</mml:mi><mml:mi>c</mml:mi></mml:msub><mml:mo>=</mml:mo><mml:mn>37</mml:mn><mml:mtext> </mml:mtext><mml:mtext>K</mml:mtext></mml:mrow><mml:mo>)</mml:mo></mml:mrow></mml:mrow></mml:math> (2009)

$\ensuremath{\alpha}\text{-FeSe}$ with the PbO structure is a key member of the family of high-${T}_{c}$ iron pnictide and chalcogenide superconductors, as while it possesses the basic layered structural motif of edge-sharing distorted ${\text{FeSe}}_{4}$ tetrahedra, it lacks interleaved ion spacers or charge-reservoir layers. We find that the application of hydrostatic pressure first rapidly increases ${T}_{c}$ which attains a broad maximum of 37 K at $\ensuremath{\sim}7\text{ }\text{GPa}$ before decreasing to 6 K upon further compression to $\ensuremath{\sim}14\text{ }\text{GPa}$. Complementary synchrotron x-ray diffraction at 16 K was used to measure the low-temperature isothermal compressibility of $\ensuremath{\alpha}\text{-FeSe}$, revealing an extremely soft solid with a bulk modulus, ${K}_{0}=30.7(1.1)\text{ }\text{GPa}$ and strong bonding anisotropy between interlayer and intralayer directions that transforms to the more densely packed $\ensuremath{\beta}$ polymorph above $\ensuremath{\sim}9\text{ }\text{GPa}$. The nonmonotonic ${T}_{c}(P)$ behavior of FeSe coincides with drastic anomalies in the pressure evolution of the interlayer spacing, pointing to the key role of this structural feature in modulating the electronic properties.
Analyzing Array Data Using Supervised Methods (2002)

Pharmacogenomics is the application of genomic technologies to drug discovery and development, as well as for the elucidation of the mechanisms of drug action on cells and organisms. DNA microarrays measure genome-wide gene expression patterns and are an important tool for pharmacogenomic applications, such as the identification of molecular targets for drugs, toxicological studies and molecular diagnostics. Genome-wide investigations generate vast amounts of data and there is a need for computational methods to manage and analyze this information. Recently, several supervised methods, in which other information is utilized together with gene expression data, have been used to characterize genes and samples. The choice of analysis methods will influence the results and their interpretation, therefore it is important to be familiar with each method, its scope and limitations. Here, methods with special reference to applications for pharmacogenomics are reviewed.
Selenium Catalyzed Conversion of d-Phenyl-g-alkenyl Oximes into 2-Phenylpyridines (1996)

8-Phenyl-y-alkenyl oximes react with an excess of ammonium persulfate and catalytic amounts of diphenyl diselenide in the presence of trifluoromethanesulfonic acid in acetonitrile to afford 2-phenylpyridines and 2-phenylpyridine N-oxides in moderate yields.We have recently introduced a very simple and efficient selenium catalyzed multistep one-pot procedure to effect several conversions of functional groups.This procedure, which consists in the selenenylation of unsaturated compounds with benzeneseleoenyl sulfate12 followed by the deselenenylation of the addition products by ammonium persulfate, can be realized simply by using an excess of ammonium persulfate and only catalytic amounts of diphenyl diselenide.Depending on the solvent employed and on the
