Walking and Wandering: Reconstructing Diasporic Subjectivity in T. C. Huo\u27s Land of Smiles and Lê Thi Diem Thúy’s The Gangster We Are All Looking For

Diaspora has often been defined as the condition of dispersal and displacement in which its members express minimal connections with their host country and always look to return to their ancestral homelands. However, from the literary representations in T. C. Huo’s Land of Smiles and Lê Thi Diem Thúy’s The Gangster We Are All Looking For, it is clear that members of the Southeast Asian diaspora determine to set root in their host country and refuse to be treated as temporary guests. This determination is warranted by their desire to redefine the contentious idea of home beyond cultural ancestry and geopolitical boundaries. Both authors utilize the trope of walking and wandering to debunk the essentialist conception based on the premise that one’s subjectivity is static, especially when it applies to diasporic members’ supposed sense of homelessness and the longing to return to their native countries. Rather than perpetuating the systemic labels onto diasporic members, such as homelessness, passivity, and powerlessness, through walking and wandering, the Southeast Asian refugees in the novels demonstrate the psychosomatic connections with their host country, take part in the pursuit of success, and declare an active, visible presence in their new homeland as fervent subjects who embrace opportunities to obtain material security in the United States

Enhancement of hopping conductivity by spontaneous fractal ordering of low-energy sites

Variable-range hopping conductivity has long been understood in terms of a canonical prescription for relating the single-particle density of states to the temperature-dependent conductivity. Here we demonstrate that this prescription breaks down in situations where a large and long-ranged random potential develops. In particular, we examine a canonical model of a completely compensated semiconductor, and we show that at low temperatures hopping proceeds along self-organized, low-dimensional subspaces having fractal dimension $d = 2$. We derive and study numerically the spatial structure of these subspaces, as well as the conductivity and density of states that result from them. One of our prominent findings is that fractal ordering of low energy sites greatly enhances the hopping conductivity, and allows Efros-Shklovskii type conductivity to persist up to unexpectedly high temperatures.Comment: 9 pages, 6 figures; published version with added references and discussio

Authentication with Distortion Criteria

In a variety of applications, there is a need to authenticate content that has experienced legitimate editing in addition to potential tampering attacks. We develop one formulation of this problem based on a strict notion of security, and characterize and interpret the associated information-theoretic performance limits. The results can be viewed as a natural generalization of classical approaches to traditional authentication. Additional insights into the structure of such systems and their behavior are obtained by further specializing the results to Bernoulli and Gaussian cases. The associated systems are shown to be substantially better in terms of performance and/or security than commonly advocated approaches based on data hiding and digital watermarking. Finally, the formulation is extended to obtain efficient layered authentication system constructions.Comment: 22 pages, 10 figure
