Diglossia in Religious Activities in Puri Agung Tegal Tamu in Gianyar

Language varieties may be classified according to the users of the language. Regarding the so-cial stratification of the society where the language is spoken, language can divided into high, middle and lower variety. Language varieties which concern with social stratification between upper and lower class speaker is mentioned as diglossia. This research aims at identifying types and meaning of diglossia occur in Puri Agung Tegal Tamu and also investigating what factors influenced the used of diglossia in religious activities since Puri becomes the center of culture and a place where the civiliza-tion begins. In Puri Agung Tegal Tamu of Gianyar Regency, religous activities often take place such as maaturan, nunas tirta and nunas muput or ngantebin. This research concludes that the diglossia is classified into formal diglossia. Its occurrence in religious activities such as: inggih (yes), uning (know), elingang (remember) as part of H language variety and nah (yes), tawang (know), inget (remember) as part of L language variety. Its meaning for H class speaker is to express the power, and it signified respect by the L class speaker. It is influenced by several factors such as: field, mode and tenor. Keywords: diglossia, religious activities, and Puri

The Language Maintenance of Mother Tongue in Tourism Area, Ubud

This study entitled "The Language Maintenance of Mother Tongue in Tourism Area, Ubud". The background of this study is departed from having seen the phenomenon of a rapid tourism development in Ubud. The arrival of tourists, both domestics and foreigners, would have an impact on the interaction be-tween tourists and local communities. The interaction is not merely the culture, but also in terms of commu-nication of how the language is being used. The use of language in daily communication is definitely become an interesting aspect to be discussed because Ubud is known as a multicultural region; some people may think that Ubud is a bule village similar to Kuta. The objective of this study is to determine whether mother tongue is still being used in Ubud, Gian-yar or had it replaced by the foreign language. In addition, this research conducted to find out the strategies used by the people of Ubud to maintain the sustainability of mother-tongue language in the region. The method used for this research is a field research. The research conducted by a non-participatory observation; researchers act to make observations and not directly involved in the interaction at the time of the study. Research techniques that used are documentations, records and depth interviews. The results ana-lyzed by approach which was proposed by Fasold (1972). It is also supported by Fishman's approach; both concern with language maintenance. The interview results are expected to answer strategies used by speakers of the local community in preserving the language. The presentation of the data described in qualitative de-scriptive method.

Coxeter groups, hyperbolic cubes, and acute triangulations

Let $C(L)$ be the right-angled Coxeter group defined by an abstract triangulation $L$ of $\mathbb{S}^2$. We show that $C(L)$ is isomorphic to a hyperbolic right-angled reflection group if and only if $L$ can be realized as an acute triangulation. The proof relies on the theory of CAT(-1) spaces. A corollary is that an abstract triangulation of $\mathbb{S}^2$ can be realized as an acute triangulation exactly when it satisfies a combinatorial condition called "flag no-square". We also study generalizations of this result to other angle bounds, other planar surfaces and other dimensions.Comment: 27 pages, 9 figures. Accepted for publication by the Journal of Topolog

Geometric phase at graphene edge

We study the scattering phase shift of Dirac fermions at graphene edge. We find that when a plane wave of a Dirac fermion is reflected at an edge of graphene, its reflection phase is shifted by the geometric phase resulting from the change of the pseudospin of the Dirac fermion in the reflection. The geometric phase is the Pancharatnam-Berry phase that equals the half of the solid angle on Bloch sphere determined by the propagation direction of the incident wave and also by the orientation angle of the graphene edge. The geometric phase is finite at zigzag edge in general, while it always vanishes at armchair edge because of intervalley mixing. To demonstrate its physical effects, we first connect the geometric phase with the energy band structure of graphene nanoribbon with zigzag edge. The magnitude of the band gap of the nanoribbon, that opens in the presence of the staggered sublattice potential induced by edge magnetization, is related to the geometric phase. Second, we numerically study the effect of the geometric phase on the Veselago lens formed in a graphene nanoribbon. The interference pattern of the lens is distinguished between armchair and zigzag nanoribbons, which is useful for detecting the geometric phase.Comment: 8 pages, 5 figure

Development of a Community-Based Spiritual Life Review Program for Promoting Resilience of Elders Residing in Disaster-Prone Areas

Background: Nowadays disasters are a common occurrence in the world. The elderly are in a vulnerable condition in terms of disasters and need help to recover from the hardship caused if they are caught in such a disaster. Two significant contributors to elderly people having sufficient resilience to be able to deal with such disasters are spiritual support and social support. Purpose: To develop a program specifically for Muslim elderly in Indonesia for promoting resilience. Method: The processes of developing the program were conducted in 2011, and included a critical review of the literature, constructing the elements of the actual program, validating the contents of the program by three experts, revising the program according to the experts‟ suggestions, and finally pilot-tested the final version of the program on a group 12 elders in Banda Aceh, Indonesia. Result: The program protocol established in this program includes five stages: (1) reviewing individual spiritual life experiences using memorable photos; (2) appreciating feelings among group members (3) re-evaluating the participant‟s life by looking to the group‟s album, (4) reconstructing the participants‟ life, and (5) affirming the six spiritual dimensions of the Islamic religion by the religious leader

Deep Learning Framework for Wireless Systems: Applications to Optical Wireless Communications

Optical wireless communication (OWC) is a promising technology for future wireless communications owing to its potentials for cost-effective network deployment and high data rate. There are several implementation issues in the OWC which have not been encountered in radio frequency wireless communications. First, practical OWC transmitters need an illumination control on color, intensity, and luminance, etc., which poses complicated modulation design challenges. Furthermore, signal-dependent properties of optical channels raise non-trivial challenges both in modulation and demodulation of the optical signals. To tackle such difficulties, deep learning (DL) technologies can be applied for optical wireless transceiver design. This article addresses recent efforts on DL-based OWC system designs. A DL framework for emerging image sensor communication is proposed and its feasibility is verified by simulation. Finally, technical challenges and implementation issues for the DL-based optical wireless technology are discussed.Comment: To appear in IEEE Communications Magazine, Special Issue on Applications of Artificial Intelligence in Wireless Communication

Properties of the one-dimensional Hubbard model: cellular dynamical mean-field description

The one-dimensional half-filled Hubbard model is considered at zero temperature within the cellular dynamical mean-field theory (CDMFT). By the computation of the spectral gap and the energy density with various cluster and bath sizes we examine the accuracy of the CDMFT in a systematic way, which proves the accurate description of the one-dimensional systems by the CDMFT with small clusters. We also calculate the spectral weights in a full range of the momentum for various interaction strengths. The results do not only account for the spin-charge separation, but they also reproduce all the features of the Bethe ansatz dispersions, implying that the CDMFT provides an excellent description of the spectral properties of low-dimensional interacting systems.Comment: J.

Renormalization analysis of intermittency in two coupled maps

The critical behavior for intermittency is studied in two coupled one-dimensional (1D) maps. We find two fixed maps of an approximate renormalization operator in the space of coupled maps. Each fixed map has a common relavant eigenvaule associated with the scaling of the control parameter of the uncoupled one-dimensional map. However, the relevant ``coupling eigenvalue'' associated with coupling perturbation varies depending on the fixed maps. These renormalization results are also confirmed for a linearly-coupled case.Comment: 11 pages, RevTeX, 2 eps figure
