Novel Compact Three-Way Filtering Power Divider Using Net-Type Resonators

In this paper, we present a novel compact three-way power divider with bandpass responses. The proposed power divider utilizes folded net-type resonators to realize dual functions of filtering and power splitting as well as compact size. Equal power ratio with low magnitude imbalance is achieved due to the highly symmetric structure. For demonstration, an experimental three way filtering power divider is implemented. Good filtering and power division characteristics are observed in the measured results of the circuit. The area of the circuits is 14.5 mm x 21.9 mm or 0.16 λg x 0.24 λg, where the λg is the guide wavelength of the center frequency at 2.1 GHz

The Influence of Chan Buddhism Spirit on Chinese Music DE L’INFLUENCE DU ZEN SUR LA MUSIQUE CHINOISE

Chan Buddhism is an influential school of Buddhism in China; the philosophic thinking it advocates has influenced Chinese music and culture in many ways, which results in four orientations of the development of Chinese music: firstly, Chinese music put emphasis on its artistic conception; secondly, Chinese music emphasizes spiritual charm; thirdly, Chinese music values self-intuition; fourthly, Chinese music values natural beauty. Key words: Chan Buddhism, Chinese music, Influence Résumé: Le Zen est un secte bouddhiste influent en Chine. Sa pensée philosophique a exercé des influences diverses sur la culture musicale chinoise, qui s’expriment dans les quatre domaines ci-dessous. Sous l’influence de la pensée de Zen, la musique chinoise insiste sur la beauté d’imagination, la beauté de spiritualité, la beauté de perception et la beauté naturelle. Mots-Clés: Zen, musique chinoise, influenc

Two-dimensional ferromagnetic semiconductor Cr2XP: First-principles calculations and Monte Carlo simulations

According to the Mermin Wagner theorem, two-dimensional material is difficult to have the Curie temperature above room temperature. By using the method of band engineering, we design a promising two-dimensional ferromagnetic semiconductor Cr2XP (X=P, As, Sb) with large magnetization, high Curie temperature and sizable band gap. The formation of gap is discussed in terms of the hybridizations, occupation and distribution of electronic states and charge transfer. Large magnetic moments about 6.16~6.37uB origin from the occupation of Cr-d electrons in crystal field.Competition and cooperation between d-d (Cr-d~Cr-d) and d-p-d (Cr-d~X-p~Cr-d) exchange interactions lead to the emergence of ferromagnetic ordering phase. Furthermore, Curie temperatures, approaching to 269 K, 332 K and 400 K for Cr2P2, Cr2AsP and Cr2SbP, are estimated by employing Monte Carlo simulation based on the Heisenberg model. Magnetic anisotropy energy of Cr2XP is determined by calculating the total energy dependence on the angle along different directions, and the origin is also discussed by the second-order perturbation theory. In addition, the Cr2XP possesses excellent thermodynamical, dynamical and mechanical stabilities, and can overcome their own gravity to keep their planar structure without the support of substrate. These above-mentioned advantages will offer some valuable hints for two-dimensional ferromagnetic semiconductor Cr2XP in spintronic devices

Pride, prejudice and pragmatism: family language policies in the UK

In this study, we examine how mobility and on-going changes in sociocultural contexts impact family language policy (FLP) in the UK. Using a questionnaire and involving 470 transnational families across the UK, our study provides a descriptive analysis of different family language practices in England and establishes how attitudes influence the different types of FLP in these families. Complementing the descriptive analysis, we use interview data to understand the driving forces behind the different types of language practices and language management activities, and explore how ideological constructs of ‘pride’, ‘prejudice’ and ‘pragmatism’ are directly related to negative or positive attitudes towards the development of children’s heritage language. The findings indicate that migration trajectories, social values, raciolinguistic policing in schools, and linguistic loyalty have shaped family decisions about what languages to keep and what languages to let go. Our paper responds to the linguistic and demographic changes in British society, and makes an important contribution to our knowledge about multilingual development of children in transnational families. Critically, this study shows that FLPs alone cannot save the minority languages; institutionally sanctioned language practices and ideologies have to make a move from limiting the use of these languages in educational contexts to legitimising them as what they are: linguistic resources and languages of pride

Introduction:The changing faces of transnational communities in Britain

In this editorial introduction, we outline the key conceptualisations andoverarching questions of this collection of studies on the changing faces of thetransnational communities in Britain. Using the nexus of migration and languageas our critical lens, we examine the internal diversities within the transnationalcommunities in Britain, evident in the emergence of groups differing on migrationtrajectories, social and educational backgrounds, linguistic repertories and statusassigned to community languages. We also explore how language shapes, and isshaped by, these internal diversities and wider socio-cultural-political dynamicsand pay particular attention to the multilingual and translanguaging practices inthese communities. We demonstrate how these communities function as sites forcontestation of language and identity that can be conflictual as well as a source ofothering. The introduction concludes with an outline of the contributions made bythe studies in this special issue, highlighting the key claims put forward by thecontributors
