Model predictive control of distributed air-conditioning loads for mitigation of solar variability

The growth of distributed solar photovoltaic (PV) generation in low-voltage grids in recent years has raised concerns about power quality disruptions introduced by solar variability. In response, some electricity utilities have introduced restrictions to new PV installations, such as imposing limits to power ramp rates and exports to the grid. These restrictions effectively require PV installations to locally compensate rapid variations in power output, such as those arising from passing clouds, by using batteries, for example. The direct control of responsive loads to follow variations in solar capacity is a cost-effective alternative to batteries to mitigate impacts to the grid. This paper explores the application of model-based predictive control (MPC) of a population of air conditioners (ACs) to achieve optimal tracking of PV generation to compensate solar variability at a substation or distribution transformer aggregation level. The proposed approach exploits an existing model for aggregate AC demand to design an MPC scheme to modulate the demand of clusters of ACs to track fluctuations in PV capacity. The effectivity of the proposed MPC scheme to achieve AC load following and regulation at different levels of PV penetration is analysed in a numerical simulation study, which shows that solar variability can be reduced by 80 to 95% at PV capacities between 25 and 10% of the peak AC demand with minimal impact to end-user comfort levels.
Validez de constructo de la versión española del Big Five Personality Trait Short Questionnaire (BFPTSQ) en adultos

There are several short personality trait measures that have been validated for use with adults, but few are specifically validated for use with adolescents. To trust such measures, we must demonstrate that they have adequate construct validity. In this research work, we develop the Spanish adaptation of the Big Five Personality Trait Short Questionnaire (BFPTSQ). This questionnaire is a short measure that assesses the five broad personality traits in adolescents and adults, and has an adequate conceptual breadth (content validity) of the primary traits represented in its items. The aim of this study was to explore the psychometric properties of this questionnaire in an adult Spanish sample. Thus, this research work analysed the factor, convergent (using the NEO-PI-R), and criterion (using scales that assess dark triad personality traits, alcohol consumption and happiness) validities as well as internal consistency, and testretest reliabilities of the BFPTSQ. The sample was composed of 262 participants; a subsample of 71 individuals also answered the NEO-PI-R, and another subsample of 42 respondents filled the BFPTSQ out again a month later. The results indicated that the five personality dimensions appeared in the obtained factor structure. Moreover, the internal consistency and test-retest reliabilities were adequate. Regarding the correlations with other measures, the majority of the associations of BFPTSQ with both NEO-PI-R and outcome scales were those expected. This study supports the construct validity of the Spanish version of the BFPTSQ in adults.
Comparison of Most-to-Least Prompting to Flexible Prompt Fading for Children with Autism Spectrum Disorder

ABSTRACT This study compared most-to-least prompting to flexible prompt fading for teaching four children with an autism spectrum disorder various expressive tasks. Using a parallel treatment design nested into a multiple probe design, researchers taught each participant how to expressively label six pictures with most-to-least prompting and six pictures with flexible prompt fading. The researchers evaluated effectiveness, maintenance, efficiency, and performance across both prompting conditions and across all participants. Results indicated that both prompting procedures were effective across all four participants. Results also indicated that flexible prompt fading led to a higher percentage of independent correct responding during teaching trials. For three of the participants, flexible prompt fading was also a more efficient procedure. Results were mixed in terms of maintenance across the four participants.
An Advanced User Interface for Exploring, Analysing and Browsing Digital Artwork Collections

We present ArtVis, an advanced user interface combining stateof-the-art visualisation techniques and tangible interaction to explore the Web Gallery of Art digital artwork collection consisting of almost 28 000 European artworks. The graphical ArtVis interface contains three separate visualisation panels that allow users to temporally, semantically and geographically investigate the digital artwork collection. The goal of ArtVis is that users can gain new insights by visually analysing and exploring a large data set rather than to only provide detailed information about individual artworks. This explorative ArtVis interaction style is further fostered by a tangible user interface where physical artefacts can be used as simple handles to drive the faceted browsing of the rich digital information space.
Epidemiology of neuromyelitis optica in Latin America

A major development over the past two decades was the recognition of recurrent neuromyelitis optica (NMO) as a particular central nervous system disorder different from multiple sclerosis (MS). Here we reviewed the epidemiology of NMO in Latin America (LATAM). A predominance of a mixed population is found in this region. Recurrent NMO in black women was described in the Caribbean Islands and in Rio de Janeiro. The prevalence of NMO in LATAM varied from 0.37/100,000 (Volta Redonda city) to 4.2/100,000 inhabitants (Caribbean Islands). NMO differs significantly from MS with respect to gender, ethnicity, morbidity and genetic susceptibility. An association of the HLA DRB1*03 alleles with NMO was described in the French Antilles, Ribeirão Preto, Rio de Janeiro and Mexico. It is not common to find familial forms of NMO. NMO represents 11.8% of all inflammatory idiopathic diseases in South America (SA). In SA, the highest frequency of NMO occurs in African Brazilian young women. The overall relative frequency of NMO among MS cases in this region was 14%, decreasing following a north-south gradient, which parallels the percentage of nonwhite people.
A Zen Garden interface for the interactive control of sonic ambiences in smart environment

In this paper we introduce SoZen, a novel interface for parameterizing aspects of ambient soundscapes including ambient music and peripheral sonifications using a Zen Garden. The SoZen system is both a stylish and aesthetic artifact in daily living environments and a computer-vision-based tangible and malleable representation for sound features. Due to the immediate correspondence between the arrangement of stones and the shape of sand with sonic features it also becomes a persistent visualization of the current sonic ambience. Thus it offers a conceptually different and `calm' way of reviewing and specifying sounds. The paper focuses on the conceptual ideas and showcases our current system. We demonstrate some initial ambiences and conclude with current ideas on how to embed and evaluate SoZen in the context of a smart apartment environment.
Whole genome expression profiling of blood cells in ovarian cancer patients -Prognostic impact of the CYP1B1, MTSS1, NCALD, and NOP14 genes

Ovarian cancer patients with different tumor stages and cell differentiation might be distinguished from each other by gene expression profiles in whole blood cell mRNA by the Affymetrix Human Gene 1.0 ST Array. We also examined if there is any association with other clinical variables, response to therapy, and residual tumor burden after surgery. Patients were divided into two groups, one with poor prognosis, advanced stage and poorly differentiated tumors (n = 22), and one group with good prognosis, early stage and well- to medium differentiated tumors (n = 11). Six genes were found to be differentially expressed: the PDIA3, LYAR, NOP14, NCALD and MTSS1 genes were down-regulated and the CYP1B1 gene expression was up-regulated in the poor prognosis group, all with p value <0.05, adjusted for mass comparison. In survival analyses, CYP1B1, MTSS1, NCALD and NOP14 remained significantly different (p<0.05). Patient groups did not differ in any transcript related to acute phase or immune responses. This minimal gene expression signature of prognostic ovarian cancer-related genes opens up an avenue for more practicable monitoring of ovarian cancer patients by simple peripheral blood tests, which may evolve into a tool to guide selection of curative and postoperative supportive therapies.
A Server-Side Solution to Cache-Based Side-Channel Attacks in the Cloud

As Cloud services become more common place, recent work have uncovered vulnerabilities unique to Cloud systems. Specifically, the paradigm promotes a risk of information leakage across virtual machine isolation via side-channels. In this paper, we investigate the current state of side-channel vulnerabilities involving the CPU cache, and identify the shortcomings of traditional defenses in a Cloud environment. We explore why solutions to non-Cloud cache-based side-channels cease to work in Cloud environments, and develop a mitigation technique applicable for Cloud security. Applying this solution to a canonical Cloud environment, we demonstrate the validity of this Cloud-specific, cache-based side-channel mitigation technique. Furthermore, we show that it can be implemented as a server-side approach to improve security without inconveniencing the client. Finally, we conduct a comparison of our solution to the current state-of-the-art.
Local Packing Density Is the Main Structural Determinant of the Rate of Protein Sequence Evolution at Site Level

Functional and biophysical constraints result in site-dependent patterns of protein sequence variability. It is commonly assumed that the key structural determinant of site-specific rates of evolution is the Relative Solvent Accessibility (RSA). However, a recent study found that amino acid substitution rates correlate better with two Local Packing Density (LPD) measures, the Weighted Contact Number (WCN) and the Contact Number (CN), than with RSA. This work aims at a more thorough assessment. To this end, in addition to substitution rates, we considered four other sequence variability scores, four measures of solvent accessibility (SA), and other CN measures. We compared all properties for each protein of a structurally and functionally diverse representative dataset of monomeric enzymes. We show that the best sequence variability measures take into account phylogenetic tree topology. More importantly, we show that both LPD measures (WCN and CN) correlate better than all of the SA measures, regardless of the sequence variability score used. Moreover, the independent contribution of the best LPD measure is approximately four times larger than that of the best SA measure. This study strongly supports the conclusion that a site's packing density rather than its solvent accessibility is the main structural determinant of its rate of evolution.
Neoadjuvant chemotherapy with trastuzumab in HER2-positive breast cancer: pathologic complete response rate, predictive and prognostic factors

The purpose of this study was to retrospectively review the pathologic complete response (pCR) rate from patients (n=86) with stage II and III HER2-positive breast cancer treated with neoadjuvant chemotherapy at our institution from 2008 to 2013 and to determine possible predictive and prognostic factors. Immunohistochemistry for hormone receptors and Ki-67 was carried out. Clinical and pathological features were analyzed as predictive factors of response to therapy. For survival analysis, we used Kaplan-Meier curves to estimate 5-year survival rates and the log-rank test to compare the curves. The addition of trastuzumab to neoadjuvant chemotherapy significantly improved pCR rate from 4.8 to 46.8%, regardless of the number of preoperative trastuzumab cycles (P=0.0012). Stage II patients achieved a higher response rate compared to stage III (P=0.03). The disease-free and overall survivals were not significantly different between the group of patients that received trastuzumab in the neoadjuvant setting (56.3 and 70% at 5 years, respectively) and the group that initiated it post-operatively (75.8 and 88.7% at 5 years, respectively). Axillary pCR post neoadjuvant chemotherapy with trastuzumab was associated with reduced risk of recurrence (HR=0.34; P=0.03) and death (HR=0.21; P=0.02). In conclusion, we confirmed that trastuzumab improves pCR rates and verified that this improvement occurs even with less than four cycles of the drug. Hormone receptors and Ki-67 expressions were not predictive of response in this subset of patients. Axillary pCR clearly denotes prognosis after neoadjuvant target therapy and should be considered to be a marker of resistance, providing an opportunity to investigate new strategies for HER2-positive treatment.
A Pseudonym-Based Signature Scheme for Dynamic Clusters in Ad Hoc Networks

Nodes in ad hoc networks often self-organize into clusters in which a node need anonymously prove the membership in some scenarios. For a self-organized cluster, any node should have the capacity to act as the cluster manger and use varying pseudonyms to keep privacy while the procedure of reissuing key is not desirable. Dynamic group signature schemes provide a probable solution, but are inappropriate because no incorruptible online TA (Trusted Authority) exists to run a group-key generation algorithm in the corruptible clusters of an ad hoc network, the opening capability are not absolutely necessary for a temporary cluster, and how to generate pseudonyms are not specified. To resolve the above problem, this paper proposes a pseudonym-based signature scheme where pseudonyms can be self-generated and messages can be bound to the self-generated pseudonyms. After the TA offline issues keys to all nodes, cluster managers can be dynamically elected and compute the public cluster-keys, which allow a node to dynamically join or leave the cluster by updating its restriction pseudonym. Then, only cluster members can sign messages on behalf of the cluster. Because the pseudonyms are self-updated and not directly bound to certificates, the signature scheme based on them must satisfy some new requirements. Hence, we formalize a security model for pseudonym-based signature schemes. The security of our scheme is proved in the random oracle model.
Efficient keyword search on graphs using MapReduce

A solution of a keyword query over graphs is a Group Steiner tree, which is rooted at a node and whose nodes collectively satisfy the query (e.g. node keywords cover all the query keywords), and in which the sum of edge weights satisfies given conditions (e.g., need to be minimum or be the first K minimal among all possible sub-graphs satisfying the query). Most existing techniques for evaluating keyword queries over graphs run on a centralized computer. We propose a new approach, SOverlapping, to evaluate keyword queries over graphs on MapReduce framework by utilizing probabilistic theory to partition graphs. The new approach has shown to be effective and efficient when tested on real graph data sets.
Behavior Identification Based on Geotagged Photo Data Set

The popularity of mobile devices has produced a set of image data with geographic information, time information, and text description information, which is called geotagged photo data set. The division of this kind of data by its behavior and the location not only can identify the user's important location and daily behavior, but also helps users to sort the huge image data. This paper proposes a method to build an index based on multiple classification result, which can divide the data set multiple times and distribute labels to the data to build index according to the estimated probability of classification results in order to accomplish the identification of users' important location and daily behaviors. This paper collects 1400 discrete sets of data as experimental data to verify the method proposed in this paper. The result of the experiment shows that the index and actual tagging results have a high inosculation.
In vitro activities of furoquinoline and acridone alkaloids against Plasmodium falciparum

The in vitro activities of furo[2,3b]quinoline and acridone alkaloids against Plasmodium falciparum were evaluated by an isotopic semimicrotest. A pyran ring in the furoquinoline nucleus and 2-O-pyranoglycoside and 2-nitro substituents in the acridone nucleus improved the antimalarial activities of the compounds. These findings provide a clue for further chemical modifications.
ANN-Based Control of a Multiboat Group for the Deployment of an Underwater Sensor Network

Underwater sensor networks (USNs) can be used for several types of commercial and noncommercial applications. However, some constraints resulting from the nature of aquatic environments severely limit their use. Due to constraints such as large propagation latency, low-bandwidth capacity, and short-distance communications, a large number of USN nodes are deployed to provide reliability in most applications. In this study, an unattended deployment approach based on the use of an autonomous boat group is proposed. A map of the deployment zone and optimal locations of USN nodes are fed into the onboard computers of the boat group. After processing these data and determining paths to be followed, the boat group deploys sensor nodes at predetermined locations. During the deployment, the boat group is controlled by an artificial neural network- (ANN-) based control system for reducing path errors. A set of performance evaluations is given to prove efficiency of the proposed control system. Performance results show that the boat group can successfully follow a predefined path set and deploy USN nodes. The tradeoffs between energy consumptions, end-to-end delay, and number of hops between underwater relay nodes of energy-efficient USN are also examined. The results indicate that increasing the number of hops reduces the total energy consumption and the end-to-end delay.
Software Assisted Transact Cache to Support Efficient Unbounded Transactional Memory

Transactional memory (TM) provides efficient, easy, deadlock-free parallel programming model for today's multicore-ubiquitous hardware platform. Implementation of TM needs to guarantee that the transaction is executed atomically and in isolation. Our paper proposes an efficient and unbounded hybrid-mode TM system with strong isolation guarantee, called HybridTCache. HybridTCache optimizes the common case by executing small transactions completely by hardware, and triggers operating system (OS) support with low overhead for the uncommon case when transaction size exceeds the hardware capacity. HybridTCache adds a new L1 cache, named TCache, to buffer transactional data for the active transaction executed by the processor. Compared with traditional log based approach, TCache provides fast bookkeeping which eliminates software logging overhead for the un-overflowed blocks, thus making both transaction commit and abort fast. A key design point of hardware TM is to support unbounded transactions. HybridTCache achieves this by introducing TCache overflow exceptions and resorting to OS to handle the overflowed blocks.
Worldwide Analysis of Genetic and Linguistic Relationships of Human Populations

Abstract In this study we relate language differences on a global scale with genetic distances for the same populations. The analysis is carried out on more populations (130) but fewer genetic systems (11) than earlier studies. We constructed an overall genetic distance matrix that allowed for missing values. A separate genetic distance matrix was also computed for each genetic system, and matching matrices of linguistic and geographic distances were associated with each genetic distance matrix, because the number of populations used differed among the genetic systems studied. Significant matrix correlations between language and genetics were found for both overall genetic distances and a substantial number of genetic systems, even when the effects of geographic distances were held constant. This demonstrates a significant correspondence between genetics and language on a global scale. Genetic matrices were correlated with two different linguistic distance matrices: one with higher (supraphyletic) taxonomic structure, in which among other features sub-Saharan Africans separate from non-Africans in the basal split and the Eurasiatic superphylum is postulated; and one without such structure. The correlations yield no genetic evidence to support the proposed higher linguistic structure. UPGMA and neighbor-joining trees were constructed for linguistic and genetic data. The proposed African split pattern is not supported by these data. Both types of trees indicate a pattern of grouping of east Asians, Arctic populations, and Australian natives separating from Caucasoid and African populations.
In Search of Contextual and Humanistic Southeast Asian Literature in English

English literature studies in Indonesia has to undergo a paradigm shift, given the demographic change of users and providers of English, to say nothing of the growing interests in Asian literature written in and/or translated into English. Mindful of our postcolonial experiences in today's cultural and political context, the use of more literary pieces from Southeast Asian countries in English Literature studies is all the more important. This paper locates Southeast Asian literature within the development of English as a Lingua Franca. Characteristic of our postmodern age is the recognition of people as human; and, in this case, Asian people as individuals, multilingual and multicultural subjects. As such, reading and evaluating works from the region may help develop a deeper understanding when defining our own place in relation to other people. It is through engaging in contextual and humanistic literary experiences that we measure and value the connection between literature and life.
