Marina La Malinche: Writing Across Cultures

Tulisan ini membahas karya pengarang perempuan Prancis, Kim Lefévre. Lefévredilahirkan di Vietnam dari ayah Prancis dan ibu Vietnam—ia sendiri kini tinggal di Prancis.Karya-karya autobiografinya berkenaan dengan kompleksitas identitas campurannya. Dalamkarya novelnya Marina la Malinche, ia menyajikan kehidupan seorang wanita penerjemah,Malinche, selama invasi Spanyol di Meksiko. Malinche saat ini dianggap oleh orang Meksikosebagai pengkhianat bangsa. Dalam novel itu Lefévre menggunakan tokoh Malinche sebagaicermin problem identitasnya. Penerjemah hanyalah seorang “pengkhianat” ketika ia menjadikorban kekuatan di luar dirinya

Generalized cylindrical coordinates for characteristic boundary conditions and characteristic interface conditions

The aim of this report is to derive generalized coordinates for the specific case of mapping only the streamwise and radial coordinate of a cylindrical coordinate system, while leaving the azimuthal coordinate unchanged. The characteristic equations and the required matrices for the transformation from conservative to characteristic form are presented for this specific case. All equations and procedures are based on previous work on generalized characteristic boundary conditions (Kim &amp; Lee, 2000) and characteristic interface conditions (Kim &amp; Lee, 2003).<br/

Generalized detailed Fluctuation Theorem under Nonequilibrium Feedback control

It has been shown recently that the Jarzynski equality is generalized under nonequilibrium feedback control [T. Sagawa and M. Ueda, Phys. Rev. Lett. {\bf 104}, 090602 (2010)]. The presence of feedback control in physical systems should modify both Jarzynski equality and detailed fluctuation theorem [K. H. Kim and H. Qian, Phys. Rev. E {\bf 75}, 022102 (2007)]. However, the generalized Jarzynski equality under forward feedback control has been proved by consider that the physical systems under feedback control should locally satisfies the detailed fluctuation theorem. We use the same formalism and derive the generalized detailed fluctuation theorem under nonequilibrium feedback control. It is well known that the exponential average in one direction limits the calculation of precise free energy differences. The knowledge of measurements from both directions usually gives improved results. In this aspect, the generalized detailed fluctuation theorem can be very useful in free energy calculations for system driven under nonequilibrium feedback control

SRAD Director\u27s Corner: Understanding North Korea and the Key to Security in East Asia

In the third installment of the SRAD Director’s Corner, Colonel George Shatzer focuses on North Korea and the Kim family regime. He reviews Becoming Kim Jong Un: A Former CIA Officer’s Insights into North Korea’s Enigmatic Young Dictator by Jung H. Pak and Rationality in the North Korean Regime: Understanding the Kims’ Strategy of Provocation by David W. Shin and shows how these books might help readers better understand North Korea’s leader Kim Jong-Un and the implications of his actions for US foreign and military policy in the region. The books also provide insights for strategists attempting to plan for security in East Asia

Comment on ``Large Slip of Aqueous Liquid Flow over a Nanoengineered Superhydrophobic Surface'' by C-H Choi and C Kim

In a recent Letter (Phys. Rev. Lett. vol 96, 066001 (2006), ref [1]), Choi and Kim reported slip lengths of a few tens of microns for water on nanoengineered superhydrophobic surfaces, on the basis of rheometry (cone-and-plate) measurements. We show that the experimental uncertainty in the experiment of Ref. [1], expressed in term of slip lengths, lies in the range 20 - 100 micrometers, which is precisely the order of magnitude of the reported slip lengths. Moreover we point out a systematic bias expected on the superhydrophobic surfaces. We thus infer that it is not possible to draw out any conclusion concerning the existence of huge slip lengths in the system studied by Choi and Kim.Comment: to appear in Physical Review Letter

Minimum Cost Homomorphisms to Locally Semicomplete and Quasi-Transitive Digraphs

For digraphs $G$ and $H$, a homomorphism of $G$ to $H$ is a mapping $f:\ V(G)\dom V(H)$such that$uv\in A(G)$implies$f(u)f(v)\in A(H)$. If, moreover, each vertex$u \in V(G)$is associated with costs$c_i(u), i \in V(H)$, then the cost of a homomorphism$f$is$\sum_{u\in V(G)}c_{f(u)}(u)$. For each fixed digraph$H$, the minimum cost homomorphism problem for$H$, denoted MinHOM($H$), can be formulated as follows: Given an input digraph$G$, together with costs$c_i(u)$,$u\in V(G)$,$i\in V(H)$, decide whether there exists a homomorphism of$G$to$H$ and, if one exists, to find one of minimum cost. Minimum cost homomorphism problems encompass (or are related to) many well studied optimization problems such as the minimum cost chromatic partition and repair analysis problems. We focus on the minimum cost homomorphism problem for locally semicomplete digraphs and quasi-transitive digraphs which are two well-known generalizations of tournaments. Using graph-theoretic characterization results for the two digraph classes, we obtain a full dichotomy classification of the complexity of minimum cost homomorphism problems for both classes
