A two-layer active power control scheme in a DC grid for contingency situation

A two-stage active power control scheme by droop-controlled DC grids for energy internet system when one converter is out of operation is proposed in this paper. In the first layer, the DC-link voltage of each DC terminal is analytically deduced according to the analytical power flow model in a meshed DC grid to make sure power support during the contingency situation. However, in the second layer, it can alter the concerned control parameters including the power set points and DC droops based on the DC-link voltage calculated in the former layer. The proposed hierarchical scheme can fast track the power change during the contingency situation such as loss of one converter. A typical four-terminal DC grid was modeled and verified in the DIgSILENT/PowerFactory to illustrate the two-laryer scheme.
Wavelength-Multiplexed Duplex Transceiver Based on III-V/Si Hybrid Integration for Off-Chip and On-Chip Optical Interconnects

A six-channel wavelength-division-multiplexed optical transceiver with a compact footprint of 1.5 × 0.65 mm2 for off-chip and on-chip interconnects is demonstrated on a single silicon-on-insulator chip. An arrayed waveguide grating is used as the (de)multiplexer, and III-V electroabsorption sections fabricated by hybrid integration technology are used as both modulators and detectors, which also enable duplex links. The 30-Gb/s capacity for each of the six wavelength channels for the off-chip transceiver is demonstrated. For the on-chip interconnect, an electrical-to-electrical 3-dB bandwidth of 13 GHz and a data rate of 30 Gb/s per wavelength are achieved.
Increased persistent Na+ current and its effect on excitability in motoneurones cultured from mutant SOD1 mice

Mutations in the enzyme superoxide dismutase 1 (SOD1) initiate a progressive motoneurone degeneration in amyotrophic lateral sclerosis (ALS). Transgenic mice overexpressing this mutation develop a similar progressive motoneurone degeneration. In spinal motoneurones cultured from presymptomatic mice expressing the glycine to alanine mutation at base pair 93 (G93A) SOD1 mutation, a marked increase in the persistent component of the Na+ current was observed, without changes in passive properties. This increase only enhanced neuronal excitability in high input conductance cells, as low input conductance cells exhibited a compensatory outward shift in the current remaining after Na+ blockade. High input conductance motoneurones tend to be large, so these results may explain the tendency of large motoneurones to degenerate first in ALS. Riluzole, at the therapeutic concentration used to treat ALS, decreased neuronal excitability and persistent Na+ current in G93A motoneurones to levels observed in the control motoneurones. Aberrations in the intrinsic electrical properties may be among the first symptoms to emerge in SOD1‐linked ALS.
Error Reduction in Multiple-Access Systems by Message Wrapping

In wireless multiple-access systems, CSMA/CA cannot eliminate packet collision completely, especially in the presence of hidden terminals. To address the problem, ZigZag decoding was proposed to resolve collisions. In this paper, we characterise the probability of decoding failure (due to rank deficiency) for a given transmission overhead. We then propose a new technique called message wrapping to further reduce the probability of decoding error. Our analytical and numerical results both show that errors can be significantly reduced by message wrapping.
Parenting and Child Development in Adoptive Families: Does Parental Sexual Orientation Matter?

This study investigated child development and parenting in 106 families headed by 27 lesbian, 29 gay, and 50 heterosexual couples (80% White, M = 42 years) with young adopted children (41% White, M = 3 years). Parents and teachers reported that, on average, children were developing in typical ways. Measures of children's adjustment, parenting approaches, parenting stress, and couple relationship adjustment were not significantly associated with parental sexual orientation. However, several family process variables—parenting stress, parenting approaches, and couple relationship adjustment—were found to be significantly associated with children's adjustment, regardless of parental sexual orientation. Implications for understanding the role of gender and sexual orientation in parenting, as well as for legal and policy debates, are discussed.
An Investigation of some Properties of an "Ant Algorithm"

We have used the metaphor of ant colonies to define "the Ant system", a class of distributed algorithms for combinatorial optimization. To test the Ant system we used the travelling salesman problem. In this paper we analyze some properties of Ant-cycle, the up to now best performing of the ant algorithms we have tested. We report many results regarding its performance when varying the values of control parameters and we compare it with some TSP specialized algorithms.
A generalized LR parser for text-to-speech synthesis

The development of a parser for a Norwegian text-to-speech system is reported. The generalized left-right (GLR) algorithm is applied, which is a generalization of the well-known LR algorithm for parsing computer languages. This paper briefly describes the GLR algorithm, the integration of a probabilistic scoring model, our implementation of the parser in C++, the attribute structures, the lexical interface, and the application of the parser to part-of-speech (POS) tagging for Norwegian. Applied to a small test set of about 4,000 words, this method correctly tags 96% of the known words, which is close to the performance of other POS-taggers trained on large text databases. 85% of the unknown words are tagged correctly, and the probability of choosing the wrong pronunciation of a word from the lexicon is less than 0.1%.
Experiments in Vision-Guided Robot Walking in a Structured Scenario

Locomotion of a biped robot in a scenario with obstacles requires a high degree of coordination between perception and walking. This article presents key ideas of a vision-based strategy for guidance of walking robots in structured scenarios. Computer vision techniques are employed for reactive adaptation of step sequences allowing a robot to step over or upon or walk around obstacles. A highly accurate visual feedback is achieved by a combination of line-based scene analysis and real-time feature tracking. The proposed vision-based approach was evaluated by experiments with a real humanoid robot. I. INTRODUCTION
Cress: Dynamic Scheduling for Resource Constrained Jobs

Applications on cloud data centers are becoming more complex and various, which makes it necessary to build a flexible and constraint-aware scheduling mechanism. On one hand, dynamic resource allocation according to workloads can achieve higher utilization to the whole system. On the other hand, workload-aware scheduling for special resource can improve the performance of those individual applications. However, it is a challenge to trade off the two goals above, especially for those cloud data centers where an amount of resident services with fluctuating workloads and constraints are running. In this paper, we propose a dynamic scheduling mechanism for resource-constrained jobs. First, a dynamic description language is introduced to describe the multi-dimensional requirements for resource-constrained jobs. Second, a workload-aware resource scheduling algorithm and a conversion method between soft and hard constraints are employed to dynamically adapt to fluctuating workload. Finally, we designed a job scheduler, called Cress, which can dynamically schedule jobs by groups under the hard and soft constraints. The experimental results present that Cress can effectively manage a mixed workload with minimal operation cost and optimal performance.
Multiclass Learnability and the ERM principle

We study the sample complexity of multiclass prediction in several learning settings. For the PAC setting our analysis reveals a surprising phenomenon: In sharp contrast to binary classification, we show that there exist multiclass hypothesis classes for which some Empirical Risk Minimizers (ERM learners) have lower sample complexity than others. Furthermore, there are classes that are learnable by some ERM learners, while other ERM learners will fail to learn them. We propose a principle for designing good ERM learners, and use this principle to prove tight bounds on the sample complexity of learning symmetric multiclass hypothesis classes--classes that are invariant under permutations of label names. We further provide a characterization of mistake and regret bounds for multiclass learning in the online setting and the bandit setting, using new generalizations of Littlestone's dimension.
Leaching behaviour of elements from coal combustion fly ash: an overview

Coal-based power generation produces over 750 Mt of coal ash per year globally, but under 50% of world production is utilised. Large amounts of fly ash are either stored temporarily in stockpiles, disposed of in ash landfills or lagooned. Coal ash is viewed as a major potential source of release of many environmentally sensitive elements to the environment. This paper encompasses over 90 publications on coal fly ash and demonstrates that a large number of elements are tightly bound to fly ash and may not be easily released to the environment, regardless of the nature of the ash. This review provides an extensive look at the extent to which major and trace elements are leached from coal fly ash. It also gives an insight into the factors underlying the leachability of elements and addresses the causes of the mobility. The mode of occurrence of a given element in the parent coal was found to play an important role in the leaching behaviour of fly ash. The amount of calcium in fly ash exerts a dominant influence on the pH of the ash-water system. The mobility of most elements contained in ash is markedly pH sensitive. The alkalinity of fly ash attenuates the release of a large number of elements of concern such as Cd, Co, Cu, Hg, Ni, Pb, Sn or Zn among others, but at the same time, it enhances the release of oxyanionic species such as As, B, Cr, Mo, Sb, Se, V and W. The precipitation of secondary phases such as ettringite may capture and bind several pollutants such ash As, B, Cr, Sb, Se and V.
Formulation and Evaluation of Long Circulating Liposomal Amphotericin B: A Scinti-kinetic Study using 99mTc in BALB/C Mice

In the present study, we formulated long circulating liposomes for amphotericin B and characterized them. The formulation was optimized using 23 factorial designs. Pegylated liposomal formulation showed favorable results with reference to particle size (247.33±9.60 nm), percent entrapment efficiency (94.55±3.34%). TEM studies revealed that the liposomes were essentially spherical, hollow, and appeared like powder puff structures. From DSC study it was concluded that the pegylated formulation containing Amp B showed better stability and membrane integrity of the formulation. During the stability studies the formulation was found to be stable. When subjected to gamma scintigraphy kinetic tracer studies the formulation showed longer residence time in the blood in BALB/C mice.

Frequency-interleaving technique for high-speed A/D conversion

This paper introduces a concept of analog-to-digital conversion for very high-speed applications. Like the time-interleaving conversion, this method uses different conventional ADCs (channels), which work in parallel, but the approach is different. The basic principle is close to techniques used in signal processing, such as the discrete Fourier transform (DFT) and sub-band coding. Because of its low sensitivity to sampling-clock jitter; this technique can achieve a 6 bit effective accuracy up to the Nyquist frequency.
Certification and regulatory challenges in medical device software development

The critical nature of safety in medical device software requires a repeatable and compliant software engineering process. This process should take into account the whole development life cycle, risk management, and software verification and validation activities that would commensurate with the device's complexity and risk. This paper discusses some of the key challenges medical device manufacturers are facing in the development and certification of medical device software. These challenges include: compliance with the EU and US regulatory requirements for medical device software, making software development and maintenance processes more agile in the medical device regulatory environment, integrating usability engineering process/human factors into software development, regulation of networked medical devices and mobile medical applications (apps). The MED-EL case study highlights some of the challenges described in this paper, and the approaches taken to overcome these challenges.
A Review on “Privacy Preservation Data Mining (PPDM)

It is often highly valuable for organizations to have their data analyzed by external agents. Data mining is a technique to analyze and extract useful information from large data sets. In the era of information society, sharing and publishing data has been a common practice for their wealth of opportunities. However, the process of data collection and data distribution may lead to disclosure of their privacy. Privacy is necessary to conceal private information before it is shared, exchanged or published. The privacypreserving data mining (PPDM) has thus has received a significant amount of attention in the research literature in the recent years. Various methods have been proposed to achieve the expected goal. In this paper we have given a brief discussion on different dimensions of classification of privacy preservation techniques. We have also discussed different privacy preservation techniques and their advantages and disadvantages. We also discuss some of the popular data mining algorithms like association rule mining, clustering, decision tree, Bayesian network etc. used to privacy preservation technique. We also presented few related works in this field.
Gender and Race Representations of Scientists in Highlights for Children

Girls lose interest in science by age 9, and researchers have attributed this finding to misrepresentations of female scientists in the media. While television, film, the Internet, textbooks, and biographies have been analyzed for such representations, this study examines the extent to which females and minorities are portrayed over time in science sections of a popular children’s magazine, Highlights for Children. Results indicate that, while males and Whites have outnumbered females and minorities in depictions of science, Highlights has consistently exceeded the number of females and minorities actually employed in scientific fields.
Reproducibility of the World Health Organization 2008 criteria for myelodysplastic syndromes

The reproducibility of the World Health Organization 2008 classification for myelodysplastic syndromes is uncertain and its assessment was the major aim of this study. The different peripheral blood and bone marrow variables required for an adequate morphological classification were blindly evaluated by four cytomorphologists in samples from 50 patients with myelodysplastic syndromes. The degree of agreement among observers was calculated using intraclass correlation coefficient and the generalized kappa statistic for multiple raters. The degree of agreement for the percentages of blasts in bone marrow and peripheral blood, ring sideroblasts in bone marrow, and erythroid, granulocytic and megakaryocytic dysplastic cells was strong (P<0.001 in all instances). After stratifying the percentages according to the categories required for the assignment of World Health Organization subtypes, the degree of agreement was not statistically significant for cases with 5-9% blasts in bone marrow (P=0.07), 0.1-1% blasts in peripheral blood (P=0.47), or percentage of erythroid dysplastic cells (P=0.49). Finally, the interobserver concordance for World Health Organization-defined subtypes showed a moderate overall agreement (P<0.001), the reproducibility being lower for cases with refractory anemia with excess of blasts type 1 (P=0.05) and refractory anemia with ring sideroblasts (P=0.09). In conclusion, the reproducibility of the World Health Organization 2008 classification for myelodysplastic syndromes is acceptable but the defining criteria for blast cells and features of erythroid dysplasia need to be refined.
The role of centaurins in vesicular trafficking and neuronal differentiation

In order to better understand the role of the phosphoinositide (PI) 3-Kinase (PI3K) pathway in neuronal differentiation and plasticity, I am studying two centaurins that are Arf GAPs and candidate targets downstream of PI3K. Arfs are small GTPases that regulate vesicular membrane trafficking within different compartments of the secretory and endosomal pathway. Centaurin alpha-1 binds PIP3 and filamentous (F)-actin, and interacts with the clathrin coat adaptor AP-3. Centaurin a-1 has a conserved GAP homology domain and has been shown to decrease Arf6 GTP levels in vivo. Other studies from our lab show that centaurin alpha-1 is required for normal dendritic branching and spine morphogenesis in developing neurons. My preliminary studies demonstrate centaurin alpha-1 has a punctate staining pattern in neurosecretory cells and neurons and colocalizes with protein markers of the regulated secretory pathway. These data support the hypothesis that centaurin alpha-1 is an Arf6 GAP involved in secretory vesicle trafficking and is required in dendritic differentiation. Centaurin gamma-2 (also called AGAP1) shows Arf1 GAP activity in vitro and in vivo. Centaurin gamma-2 binds PIP3 and AP-3, and overexpression in non-neuronal cells results in transferrin accumulation in the recycling endosome. Centaurin gamma-2 was also identified as a candidate autism susceptibility gene. My preliminary data
North by Northwest: Infrastructure Agnostic and Datastore Agnostic Live Migration of Private Cloud Platforms

Cloud technology is evolving at a rapid pace with innovation occurring throughout the software stack. While updates to Software-as-a-Service (SaaS) products require a simple push of code to the production servers or platform, updates to the Infrastructure-as-a-Service (IaaS) or Platform-as-a-Service (PaaS) layers require more intricate procedures to prevent disruption to services at higher abstraction layers. In this work we address the need for rolling upgrades to PaaS systems. We do so with the App-Scale PaaS, which is amulti-application, multi-language, multi-infrastructure, and multi-datastore platform. Our design and implementation allows for applications and tenants to be migrated live from one cloud deployment to another with guaranteed transaction semantics and minimal performance degradation. In this paper we motivate the need for PaaS migration support and empirically evaluate migrations between two AppScale deployments using highly scalable datastores.
Internal Memory Gate for Recurrent Neural Networks with Application to Spoken Language Understanding

Long Short-Term Memory (LSTM) Recurrent Neural Networks (RNN) require 4 gates to learn shortand long-term dependencies for a given sequence of basic elements. Recently, “Gated Recurrent Unit” (GRU) has been introduced and requires fewer gates than LSTM (reset and update gates), to code shortand long-term dependencies and reaches equivalent performances to LSTM, with less processing time during the learning. The “Leaky integration Unit” (LU) is a GRU with a single gate (update) that codes mostly long-term dependencies quicker than LSTM or GRU (small number of operations for learning). This paper proposes a novel RNN that takes advantage of LSTM, GRU (shortand long-term dependencies) and the LU (fast learning) called “Internal Memory Gate” (IMG). The effectiveness and the robustness of the proposed IMG-RNN is evaluated during a classification task of a small corpus of spoken dialogues from the DECODA project that allows us to evaluate the capability of each RNN to code short-term dependencies. The experiments show that IMG-RNNs reach better accuracies with a gain of 0.4 points compared to LSTMand GRU-RNNs and 0.7 points compared to the LU-RNN. Moreover, IMG-RNN requires less processing time than GRU or LSTM with a gain of 19% and 50% respectively.
Transport of the IgE Receptor α-Chain Is Controlled by a Multicomponent Intracellular Retention Signal*

The human high affinity IgE receptor (FcϵRI) is a central component of the allergic response and is expressed as either a trimeric αγ2 or tetrameric αβγ2 complex. It has been previously described that the cytoplasmic domain (CD) of the α-chain carries a dilysine motif at positions -3/-7 from the C terminus that functions in intracellular retention prior to assembly with other FcϵRI subunits. In this report we have further explored the role of the -3/-7 dilysine signal in controlling steady-state α-chain transport by mutational analysis and found little surface expression of a -3/-7 dialanine α-chain mutant but significant Golgi localization. We compared the transport properties of a series of α-chain cytoplasmic domain truncation mutants and observed that truncation mutants lacking 23 or more C-terminal residues showed a dramatic increase in steady-state transport suggesting a role for the membrane-proximal CD sequence in α-chain retention. By performing alanine-scanning mutagenesis we identified a dilysine sequence (Lys212-Lys216) proximal to the transmembrane domain (TMD) that is important for both α-chain cell-surface expression and intracellular stability. Furthermore, co-mutation of the Lys212-Lys216 residues with the -3/-7 dilysine signal produced a dramatic increase in α-chain surface expression that was further increased by co-mutation of the lone charged residue (Asp192) in the TMD thereby defining three regions that function to regulate α-chain transport and in a highly synergistic manner.
