The migrant voice : the politics of writing home between the Sinophone and Anglophone worlds

This paper addresses the politics of language, identity, and diasporic Chinese writing in old and emerging Chinese migrant literature. I opt for the idea of a “migrant subject” as brought up by Ha Jin to underscore a diverse verbal strategy and mobile literary creativity: that of the migrant writer who initiates linguistic and literary perversions to actively intervene in the cultural politics of both the host country and the motherland. The article proceeds to recuperate the diasporic narratives of Sinophone authors Bai Xianyong and Nie Hualing as two earlier examples of migrant writers before Ha, which exemplified the Cold War phase of overseas Chinese American writing. Whereas writing in an adopted tongue of English, as attested by Ha himself, unleashes his creative and critical urges, for Bai and Nie writing in Chinese in a foreign land as America does likewise and ushers in the critical distance cherished by the migrant writers to work on such subject matters as exile and cultural alienation. Originally written in Chinese or English, their migrant voices bring in a minor language to major traditions (Chinese literature and American English literature). Tracing the historical trajectory of migrant literature, in which Sinophone and Anglophone texts are increasingly translated and circulated between cultures, I stress the gains in translation and intercultural writing as the migrant subject can stand valid as a position for writers of transnational literary creativity

Sensing and mapping for interactive performance

This paper describes a trans-domain mapping (TDM) framework for translating meaningful activities from one creative domain onto another. The multi-disciplinary framework is designed to facilitate an intuitive and non-intrusive interactive multimedia performance interface that offers the users or performers real-time control of multimedia events using their physical movements. It is intended to be a highly dynamic real-time performance tool, sensing and tracking activities and changes, in order to provide interactive multimedia performances. From a straightforward definition of the TDM framework, this paper reports several implementations and multi-disciplinary collaborative projects using the proposed framework, including a motion and colour-sensitive system, a sensor-based system for triggering musical events, and a distributed multimedia server for audio mapping of a real-time face tracker, and discusses different aspects of mapping strategies in their context. Plausible future directions, developments and exploration with the proposed framework, including stage augmenta tion, virtual and augmented reality, which involve sensing and mapping of physical and non-physical changes onto multimedia control events, are discussed

The Effects of Majorana Phases in Estimating the Masses of Neutrinos

Majorana CP violating phases coming from heavy right-handed Majorana mass matrices ($M_{RR}$) are considered to estimate the masses of neutrinos.The effects of phases on quasi-degenerate neutrinos mass matrix obeying $\mu$-$\tau$ symmetry predicts the results consistent with observations for (i) solar mixing angle($\theta_{12}$) below TBM, (ii) absolute neutrino mass parameters[$m_{ee}$] in neutrinoless double beta ($0\nu\beta\beta$) decay, and (iii) cosmological upper bound $\sum_{i}m_{i}$. Analysis is carried out through parameterization of light left-handed Majorana neutrino matrices $(m_{LL})$ using only two unknown parameters $(\epsilon,\eta)$ within $\mu$-$\tau$ symmetry. We consider the charge lepton and up quark matrices as diagonal form of Dirac neutrino mass matrix $(m_{LR})$, and $m_{RR}$ are genrated using $m_{LL}$ through inversion of Type-I seesaw formula. The analysis shows that the masses of neutrinos are in agreement with the upper bound from cosmology and neutrinoless double beta decay. The results presented in this article will have important implications in discriminating the neutrinos mass models.Comment: arXiv admin note: substantial text overlap with arXiv:1206.343

Non-conservation of Density of States in Bi2_2Sr2_2CaCu2_2Oy_y: Coexistence of Pseudogap and Superconducting gap

The tunneling spectra obtained within the ab-plane of Bi$_2$Sr$_2$CaCu$_2$O$_y$ (Bi2212) for temperatures below and above the critical temperature (T$_c$) are analyzed. We find that the tunneling conductance spectra for the underdoped compound in the superconducting state do not follow the conservation of states rule. There is a consistent loss of states for the underdoped BI2212 implying an underlying depression in the density of states (DOS) and hence the pseudogap near the Fermi energy (E$_F$). Such an underlying depression can also explain the peak-dip-hump structure observed in the spectra. Furthermore, the conservation of states is recovered and the dip-hump structure disappears after normalizing the low temperature spectra with that of the normal state. We argue that this is a direct evidence for the coexistence of a pseudogap with the superconducting gap.Comment: 5 pages, 4 figure

Fast scintillation counter preamplifier for the observation of Linsley effect

A fast preamplifier circuit has been designed and thoroughly tested for the purpose of observing the air shower arrival directions including the Linsley effect. The circuit intends to eliminate the time jitter due to variation of scintillation counter signal amplitudes. It assumes that the output signals from one counter system have the same rise time. On this basis, error arising from time jitter is removed by voltage discrimination at about half signal amplitudes. Detailed description of the circuit is reported
