Quantum lithography: A?non-computing application of quantum information

Quantum information theory holds the promise of revolutionizing technologies other than computing and communications. In this article we show how quantum entanglement can be harnessed to beat the Rayleigh diffraction limit of conventional optical lithography, and to permit nano-devices to be fabricated at a scale arbitrarily shorter than the wavelength used. Given the relative ease of performing optical lithography compared with other schemes, and the relative costs associated in migrating the lithography industry to each new fabrication technology, exploiting quantum entanglement to extend the useful life of optical lithography could be economically attractive.     

A new Lyapunov functional approach to sampled-data synchronization control for delayed neural networks

This paper discusses the problem of synchronization for delayed neural networks using sampled-data control. We introduce a new Lyapunov functional, called complete sampling-interval-dependent discontinuous Lyapunov functional, which can adequately capture sampling information on both intervals from $r(t?\overline{\tau })$ to $r(t_k?\overline{\tau })$ and from $r(t?\overline{\tau })$ to $r(t_{k+1}?\overline{\tau })$. Based on this Lyapunov functional and an improved integral inequality, less conservative conditions are derived to ensure the stability of the synchronization error system, leading to the fact that the drive neural network is synchronized with the response neural network. The desired sampled-data controller is designed in terms of solutions to linear matrix inequalities. A numerical example is provided to demonstrate that the proposed approaches are effective and superior to some existing ones in the literature.

Inhibitory activities of microalgal extracts against Epstein-Barr virus DNA release from lymphoblastoid cells

This study aimed to assess the inhibitory activities of methanol extracts from the microalgae Ankistrodesmus convolutus, Synechococcus elongatus, and Spirulina platensis against Epstein-Barr virus (EBV) in three Burkitt's lymphoma (BL) cell lines, namely Akata, B95-8, and P3HR-1. The antiviral activity was assessed by quantifying the cell-free EBV DNA using real-time polymerase chain reaction (PCR) technique. The methanol extracts from Ankistrodesmus convolutus and Synechococcus elongatus displayed low cytotoxicity and potent effect in reducing cell-free EBV DNA (EC(50)<0.01 μg/ml) with a high therapeutic index (>28000). After fractionation by column chromatography, the fraction from Synechococcus elongatus (SEF1) reduced the cell-free EBV DNA most effectively (EC(50)=2.9 μg/ml, therapeutic index>69). Upon further fractionation by high performance liquid chromatography (HPLC), the sub-fraction SEF1'a was most active in reducing the cell-free EBV DNA (EC(50)=1.38 μg/ml, therapeutic index>14.5). This study suggests that microalgae could be a potential source of antiviral compounds that can be used against EBV.     

PUBLIC EDUCATION ABOUT NORMAL FORGETFULNESS AND DEMENTIA: EFFECTIVENESS OF A SYSTEMATICALLY DEVELOPED INFORMATION BROCHURE

Earlier research revealed that many elderly people in The Netherlands are worried about their forgetfulness and are afraid of incipient dementia. Until now, no systematic research has been conducted on the effects of public education about normal forgetfulness and dementia, and therefore an information brochure was developed and evaluated. The main function of this brochure was to reassure people who were unnecessarily worrying about possible dementia. A second function was to motivate people to seek professional help when this seemed advisable. Sixty‐two percent of all respondents (307 of 400) who had been worried about dementia before reading the brochure said that their anxiety decreased or disappeared after reading it; approximately 3% became more worried after reading the brochure. A cognitive test battery was administered to 104 people to determine whether their increased or decreased anxiety was justified. Thirty subjects had low test scores, yet 16 of these subjects had been reassured by the brochure that their forgetfulness was nothing to worry about. This group was characterized as experiencing fewer problems in daily life as a result of their forgetfulness and as having a higher internal locus of control. Seventy‐four subjects performed well on the cognitive tests, yet 18 of them had remained worried about their forgetfulness after reading the brochure. Anxiety for heredity of dementia could be a possible explanation for their persistent concern. Although many people were reassured by the brochure, the results also show that it is important to evaluate information brochures used as intervention instruments—in one third of the present sample, the effects of the brochure were not in accordance with its goal.     

Professional Characteristics and Teacher Professionalism of Secondary School Teachers

Questionnaire responses from 338 secondary school teachers were analysed to relate teachers' professional characteristics (comprising teaching experience, professional development, and academic and professional qualifications) to teacher professionalism, defined in terms of the two dimensions, teaching competence and commitment to teaching. The Professional Development and Teacher Professionalism Instrument (PDTPI) was devised to measure professional development and teacher professionalism. Inferential statistical techniques employed in the study showed that the variable, teaching experience, was not related to teacher professionalism. Professional development, on the other hand, was found to be an important variable, with the mean teacher professionalism scores between the “high” and “low” professional development groups being significantly different. The study also found that academic qualification was not related to teacher professionalism. However, teachers who had higher professional qualifications were found to possess a higher degree of teacher professionalism.

Developing Multicultural Competence Using the Structured Peer Group Supervision Model

Interest in the role of supervision in counselor training has increased concurrent with the interest in effective strategies for developing multicultural counseling competency. L. D. Borders (1991) proposed a model of group supervision appropriate for use with supervisees of differing skill levels; however, the model does not overtly provide for supervisees' development of multicultural awareness and skills. This article presents a format of peer group multicultural supervision in which supervisees work to increase their multicultural competencies while engaging in helper roles important for working with culturally diverse clients.     

Multiculturalism,Diversity, and Social Advocacy: A 17‐Year Content Analysis of Counselor Education and Supervision

The authors summarized (a) data regarding multiculturalism, diversity, and social advocacy represented in Counselor Education and Supervision (CES) over a 17‐year period (1989–2005, Volumes 28–45); (b) type of articles (i.e., research vs. theory) represented; (c) research methodology and applications used; (d) journal editor and related terms; (e) primary contributors and related institutional affiliations; and (f) the breadth and scope of the data regarding key topics represented. Seventy‐eight articles met inclusion criteria. Data indicate the extent to which multiculturalism, diversity, and social advocacy were represented in CES.
