A Novel Self-Learning Differential Evolution Algorithm in Two-State Dynamic Optimization

In this paper we propose a novel differential evolution algorithm based on self-learning, in order to improve the environment adaptive ability of the population in dynamic optimization. The proposed algorithm can monitor the environment changes using re-evaluation of individuals. We direct the population evolution based on the current best individual and another two random individuals, so that the convergence speed is faster and the diversity of the population is maintained. In this way we may reduce the influence from the frequent environment changes. Testing on six dynamic functions, we study the influences caused by period and dimensions. We also compared the proposed algorithm with existing algorithms, the experimental results show that our algorithm has a better environment adaptive ability and achieves better optimization result.

A New Communication Scheme Implying Amplitude Limited Inputs and Signal Dependent Noise: System Design, Information Theoretic Analysis and Channel

I propose a new communications scheme where signature signals are used to carry digital data by suitably modulating the signal parameters with information bits. One possible application for the proposed scheme is in underwater acoustic (UWA) communications; with this motivation, I demonstrate how it can be applied in UWA communications. In order to do that, I exploit existing parameterized models for mammalian sounds by using them as signature signals. Digital data is transmitted by mapping vectors of information bits to a carefully designed set of parameters with values obtained from the biomimetic signal models. To complete the overall system design, I develop appropriate receivers taking into account the specific UWA channel models. I present some numerical results from the analysis of data recorded during the Kauai Acomms MURI 2011 (KAM11) UWA communications experiment. It is shown that the proposed communication scheme results in approximate channel models with amplitude-limited inputs and signal-dependent additive noise. Motivated by this observation, I study capacity of amplitude-limited channels under di↵erent transmission scenarios. Specifically, I consider fading channels, signaldependent additive Gaussian noise channels, multiple-input multiple-output (MIMO) systems and parallel Gaussian channels under peak power constraints. I also consider practical channel coding problems for channels with signaldependent noise. I consider two specific models; signal-dependent additive Gaussian noise channels and Z-channels which serve as binary-input binary-output approximations to the Gaussian case. I propose a new upper bound on the probability of error, and utilize it for design of codes. I illustrate the tightness of the derived bounds and the performance of the designed codes via examples.
Determinants of User Acceptance of Electronic Recordkeeping Systems: A User-Focused Empirical Study of System Characteristics / Caractéristiques déterminantes de l’acceptation des systèmes de gestion des documents électroniques par les utilisateurs: Une étude empirique orientée utilisateurs des cara

This article presents the findings of an empirical study exploring a set of system characteristics that influence users’ acceptance of electronic recordkeeping systems. Thirty-four semi-structured interviews were conducted with general users (i.e., non-specialists in information and records management), from which 10 system characteristics were identified, for example, sharing, integrated, and complete. In addition, this study has identified three moderating factors (i.e., gender, organizational context, and occupational difference) that influence the strength of the relationship between the set of system characteristics and users’ perceptions of electronic recordkeeping systems. Based on the results of this study and the Technology Acceptance Model, this article proposes a research model describing how the set of system characteristics and the moderating factors influence users’ perceptions of electronic recordkeeping systems. Given that records management work is no longer purely the responsibility of information and records management specialists but rather is increasingly part of every employee’s duties, it is vital to gain an understanding of the external variables that have an impact on users’ perceptions of electronic recordkeeping systems and that may enhance users’ intention to use these systems.Cet article présente les découvertes d’une étude empirique explorant un ensemble de caractéristiques systémiques qui influence l’acceptation par les utilisateurs des systèmes de gestion des documents électroniques. Trente-quatre entrevues semi-dirigées ont été conduites avec des utilisateurs non-spécialistes (c.-à-d. nonspécialistes de gestion de l’information/archives), à partir desquelles dix caractéristiques des systèmes ont été identifiées, par exemple, le partage, l’intégration, la complétude, etc. En complément, cette étude a identifié trois facteurs modérateurs (c.-à-d. genre, contexte organisationnel, et différence occupationnelle) qui influence le force de la relation entre les caractéristiques des systèmes et la perception des systèmes par les utilisateurs. A partir des résultats de cette étude et du model d’acceptation technologique (Technology Acceptance Model), cet article propose un modèle de recherche décrivant comment les caractéristiques des systèmes et les facteurs modérateurs influencent la perception des systèmes par les utilisateurs. Étant donné que le travail de gestion des documents n’est plus entièrement la responsabilité des spécialistes mais de plus en plus reparti sur l’ensemble des employés, il est vital de mieux comprendre les variables externes qui ont un impact sur la perception des systèmes de gestion documentaire, et qui peuvent induire les utilisateurs à utiliser ces systèmes.

Directing attention in 360-degree video

360° video and Virtual Reality are powerful techniques for giving viewers a sense of `Being There' [1], and are becoming increasingly popular. However, giving the viewer the freedom to look around also results in a reduced ability for filmmakers to direct the viewer's attention, a serious impediment to successfully telling a story within a 360° environment. We have created a number of 360° clips, filmed in such a way as to demonstrate and test several unobtrusive techniques for directing a viewer's attention within a 360° panorama. We have evaluated these techniques in a user study in which participants viewed these clips using a head-mounted display. Qualitative and quantitative data from these tests have been analysed to evaluate the effectiveness of the different attention-directing techniques. Qualitative data was also captured to explore the effect of the camera being addressed directly, and the viewers' responses to action occurring at a range of distances.

Short Story Based Language Teaching (Ssblt): A Literature-Based Language Teaching Method

Notwithstanding the past belief, recently there have been some attempts by scholars who encourage the incorporation of literature in language classes. In other words, literature has been discovered as a valuable and interesting material for improving students’ language ability. There exists a variety of language teaching methods that all receive conspicuous criticisms by scholarsthough there are still at workbut there is not yet a language teaching method solely based on literature as the authentic material. The purpose of this paper is two-fold: first, it accentuates the importance and benefits of using literatureshort story in particularin language teaching and second, considering the importance of continuous progress and innovation in language teaching methods on one hand and the advantages of using short stories in language classes, a new language teaching methods as Short Story based Language Teaching (SSBLT) is introduced here. SSBLT is a humanistic literature-based language teaching method that aims to promote the learners` personal, cultural and linguistic awareness. Its main purpose is to help learners to learn language by enjoying and help them use language for communication through using short stories as the materials in a friendly atmosphere. It is particularly designed to develop communicative competence and critical thinking. In the end, the paper discusses the teaching procedures and advantages of SSBLT.

Biochemical and Biological Properties of Soil from Murundus Wetlands Converted into Agricultural Systems

The implementation of conservationist systems that improve soil properties and reduce the impacts of the conversion of native areas is fundamental for feasible agricultural exploitation. This study aimed to evaluate the impact on soil biological properties caused by the conversion of murundus fields into agricultural systems and verify the ability of the no-tillage conservation system to recover these properties over the years. Treatments consisted of three agricultural areas subjected to the same management (no-tillage), in a chronosequence (7, 11, and 14 years of conversion) and a reference area (murundus field). To evaluate soil quality, we analyzed total soil organic carbon, microbial biomass carbon, soil basal respiration, metabolic and microbial quotients, and acid phosphatase activities, as well as the potential functionality of soil bacterial communities and the modifications in their genetic structure. The conversion of murundus field into agricultural systems negatively impacted soil biological properties, with expressive reduction in soil organic carbon content and microbial biomass carbon. The periods of adoption of the conservationist system (no-tillage) were not enough to recover the biological properties and/or to reverse the changes observed in the genetic structure of the soil bacterial communities of the managed areas, although stabilization trends were observed in the agricultural systems over the years.
Application of Artificial Neural Network Algorithm in Retrieving Atmospheric Temperature Profiles from Hyperspectral Infrared Data

The artificial neural network algorithm is presented in this paper to retrieve the temperature profiles under clear skies by using AIRS(Atmospheric InfraRed Sounder) actual observations.The study is focused on the comparison of artificial neural network retrieval algorithm with eigenvector regression algorithm which has already been well developed.The results show that these two algorithms cost nearly the same computing time with comparative precision in the real AIRS data retrieval process.Due to the statistic-physical nature of the artificial neural network algorithm,it is expected to improve the temperature retrieval precision on the basis of selecting network type and modifying the network parameters sequentially.
Creation of gene expression database on preeclampsia-affected human placenta

Publication of gene expression raw data in open access at online resources like NCBI or ArrayExpress made it possible to use these data for cross-experiment integrative analysis and make new insights into biological phenomena. However, most popular of the present online resources are meant to be archives rather than ready for immediate access and interpretation databases. Data uploaded by independent contributors is not standardized and sometimes incomplete and needs further processing before it is ready for the analysis. Hence, the need for a specialized database appears. Given in this article is the description of the database that was created after processing a collection of 33 relevant datasets on pre-eclampsia-affected human placenta. Data processing includes the choice of relevant experiments from ArrayExpress database, the experiment sample attributes standardization according to MeSH term dictionary and Experimental Factor Ontology and the completion of missing data using information from the corresponding articles and authors. A database of more than 1000 samples contains sufficient sample-wise metadata for them to be arranged into relevant case-control groups. Metadata includes information on biological specimen, donor’s diagnosis, gestational age, mode of delivery etc. The average size of these groups will be higher than it is in separate experiments. This will reduce experiment bias and enhance statistical accuracy of the subsequent analysis such as search for differentially expressed genes or inferring gene networks. The article concludes with the guidelines for the microarray experiment metadata uploading for future contributors.
A new one-step synthesis of 1,2,4 -triazino [2,3 -c ]-quinazolines

A new and efficient one-step protocol for the synthesis of 3-substituted 2H-l,2,4-triazino[2,3-c]quinazolin-2-ones (5) was developed starting from 4-hydrazinoquinazoline (1) and α-ketocarboxylic acids and their esters. Corresponding hydrazones (2a,c and 3a,c,e) were isolated as intermediate products. Further cyclocondensation followed by acid-catalyzed Dimroth rearrangement resulted in the title derivatives 5.
Mechanical behaviour of MWCNTs reinforced electrospun nanofibres

Abstract The nanoscale dimension of electrospun polymeric nanofibres produced by electrospinning are highly captivating, yet facing limitation of resisting external forces due to the weak tensile properties. Carbon nanotubes providing tremendous toughness due to extraordinary strong sp2 bonding network of carbon atoms in honeycomb lattice structure, augmented the physical resistant strength and is easily recover to its original state after load is removed. This study reports the performance of multi-walled carbon nanotubes (MWCNTs) as filler in the electrospinning of poly (L-lactide)-co-ε-caprolactone) (PLCL) composite nanofibres. Voltage of 10 kV is applied to the spinning solution mixture of 11 wt% (w/v) PLCL and MWCNTs, yielded nanofibres having diameters less than 400 nm. Results obtained showed the formation of composite nanofibres with tailored tensile behavior by modifying the content of MWCNTs. The addition of MWCNTs improved the tensile properties of resultant composite nanofibres, signified by tensile strength of 5.82 to 15.95 MPa, which were obtained using 0.1 to 1.0 wt% of MWCNTs. The structural integrity of nanofibres mats were retained in phosphate buffer saline (PBS) medium. Scanning Electron Microscopy (SEM) micrographs revealed the minimal of fiber deformation over 30 days of incubation and are closely identical to the initial diameter of as-spun fiber.
Nitrato encapsulado em substituição ao farelo de soja na terminação de bovinos de corte em confinamento

Objetivou-se avaliar a inclusao crescente de nitrato encapsulado (ENP) como fonte de nitrogenio nao proteico em substituicao do farelo de soja sobre variaveis de digestibilidade, desempenho, residuos de nitrato e nitrito na carne, variaveis de comportamento ingestivo, metemoglobina e os constituintes sanguineos de novilhos terminados em confinamento. Cento e vinte novilhos nao castrados (339,5 ± 28,3 kg) foram divididos em grupos de 6 animais, alojados em 20 baias e distribuidos em um delineamento em blocos casualizados com 5 blocos e 4 tratamentos: Controle (CTL) - farelo de soja; ENP-1 - 1% ENP (0,65% NO3-) na MS da dieta; ENP-2 - 2% ENP (1,30% NO3-); ENP-3-3% ENP (1,95% NO3-). As dietas foram compostas com relacao 90:10 concentrado: forragem (bagaco de cana in natura). O experimento durou 84 dias. O consumo de materia seca diminuiu linearmente (9,6-8,4 kg / dia; P 0,05) pelos tratamentos. Houve tendencia quadratica (0,121, 0,130, 0,128, 0,127, respectivamente; P = 0,07) para ganho em carcaca. A concentracao de nitratos na carne aumentou linearmente (3,48, 2,73, 3,98, 6,59 mg NO3- / kg de carne fresca; P = 0,02) com a adicao ENP, embora nitrito (NO2-) nao foi detectado. Houve uma tendencia para a reducao quadratica (P=0,07) no tempo por unidade de ingestao de materia seca e reducao quadratica (P 0,05) para os tratamentos. Entretanto, houve um efeito quadratico (P<0,01) para triglicerideos no sangue, e aumento linear para o colesterol total (P=0,05), as variaveis ureia (P<0,01), aspartato aminotransferase (P <0,01) e gama-glutamil transferase (P=0,04) resultaram em efeito linear decrescente. A digestibilidade aparente de nutrientes teve efeito quadratico para todos os nutrientes com os niveis crescentes de nitrato encapsulado substituindo farelo de soja nas dietas. Em conclusao, o produto nitrato encapsulado nao mostrou riscos de desenvolvimento da metahemoglobinemia ate a dosagem de 3% e pode ser utilizado como fonte de nitrogenio em dietas para terminacao de bovinos. O nitrato encapsulado e seguro e aplicavel na alimentacao de ruminantes.

Biochemical analysis of yeast pre-replicative complex assembly.

The boundaries of replication research would be greatly extended by the establishment of an origin-dependent in vitro DNA replication system. Saccharomyces cerevisiae is a prime candidate from which to develop such a system, as it initiates replication from specific, well conserved, short origin sequences. The first step towards producing a yeast cell free replication system was the development of a method to assemble pre-replicative complexes (pre-RCs) onto short repeat sequences of the origin ARSl, immobilised on Dynabeads. I have extended this research to use plasmids with ARSl origins. The plasmids are competent for pre-RC assembly (ORC, Cdc6p, MCM) and this is specific for origin sequences with an A element, the element known to be essential for replication in vivo. Formation of the complexes is also time dependent and once the MCM complex has been loaded, it can stay associated even in the absence of the MCM loader Cdc6p. This is in accordance with in vivo data and suggests that the system will be useful to elucidate in vivo mechanisms of replication. I have also explored the kinetics of pre-RC assembly using different nucleotides and competitor ARSl DNA. Different steps in pre-RC assembly have different nucleotide requirements and the loading of substantial levels of the MCM complex requires the hydrolysis of ATP. Loaded MCM complexes are stable on DNA, even in the presence of competitor ARS1 plasmid. I have further investigated the nucleotide requirements using mutants of Cdc6p with changes in an ATP interaction region. Recombinant Cdc6p was produced in E. coli and purified by means of a poly-histidine tag. Cdc6p or mutant cdc6p was also expressed as a second copy in yeast cells and extracts were produced containing these proteins. Experiments with rCdc6p or the yeast extracts produced comparable results. I have successfully established in vitro loading of pre-replicative complexes at ARS 1 origins on plasmid DNA and begun to investigate the requirements of this system.
