TL;DR: In this paper, an anthropological approach to the symbolic classificatory process of U.S. immigration and nationality law is outlined, emphasizing its performance in situations of state power.
Abstract: U.S. immigration and nationality law is viewed as a set of classifications that contribute to the transfer of value between classes. An anthropological approach to the symbolic classificatory process is outlined, emphasizing its performance in situations of state power. Ethnographic observations document the actual practice of Immigration and Naturalization Service classification and reveal covert symbolic categories and plausible constructs about migrants. However, migrants are accorded an active role in struggling with and responding to dominant classifications. Three important results of immigration classification are the increased exploitation of undocumented immigrants, categorized as outlaws and obliged to undertake the risk of crossing a heavily enforced boundary; the complex maneuvering and segmentation within immigrant communities induced by the rewards of legal visa categories; and the confirmation of stereotypes about migrants in the dominant society that underwrite their employment as inexpens...

Journal ArticleDOI
TL;DR: In this article, Piecuch et al. proposed a completely renormalized (CR) coupled-cluster (CC) method with singles, doubles, and noniterative triples, termed CR-CC(2,3), which has been previously applied to singlet excited states of closed-shell molecular systems.
Abstract: The recently proposed left-eigenstate completely renormalized (CR) coupled-cluster (CC) method with singles, doubles, and noniterative triples, termed CR-CC(2,3) Piecuch and Wloch, J Chem Phys, 2005, 123, 224105; Piecuch et al Chem Phys Lett, 2006, 418, 467 and the companion CR-EOMCC(2,3) methodology, which has been previously applied to singlet excited states of closed-shell molecular systems Wloch et al Mol Phys, 2006, 104, 2149 and in which relatively inexpensive noniterative corrections due to triple excitations derived from the biorthogonal method of moments of CC equations (MMCC) are added to the CC singles and doubles (CCSD) or equation-of-motion (EOM) CCSD energies, have been extended to excited states of open-shell species The resulting highly efficient computer codes for the open-shell CR-EOMCC(2,3) approach exploiting the recursively generated intermediates and fast matrix multiplication routines have been developed and interfaced with the GAMESS package, enabling CR-EOMCC(2,3) calculations for singlet as well as nonsinglet ground and excited states of closed- and open-shell systems using the restricted Hartree–Fock or restricted open-shell Hartree–Fock references A number of important mathematical and algorithmic details related to formal aspects and computer implementation of the CR-EOMCC(2,3) method have been discussed, in addition to overviewing the key concepts behind the CR-EOMCC(2,3) and biorthogonal MMCC methodologies for ground and excited states, and the numerical results involving low-lying states of the CH, CNC, C2N, N3, and NCO species, including states dominated by two-electron transitions, have been presented The results of the CR-EOMCC(2,3) calculations have been compared with other CC/EOMCC approaches, including the EOMCCSD and EOMCC singles, doubles, and triples methods, and their full and active-space valence counterparts based on the electron-attached and ionized EOMCC methodologies, and the predecessor of CR-EOMCC(2,3) termed CR-EOMCCSD(T) Kowalski and Piecuch, J Chem Phys, 2004, 120, 1715 © 2009 Wiley Periodicals, Inc Int J Quantum Chem, 2009

TL;DR: In this paper, a model of the mechanical alloying process, applicable to a single collision event involving ductile species, is developed, where simple physical models are constructed that allow development of analytical expressions for particle shape and hardness changes during a collision and stipulation of criteria for particle fracture and cold welding.
Abstract: A model of the mechanical alloying process, applicable to a single collision event involving ductile species, is developed. Simple physical models are constructed that allow development of analytical expressions for particle shape and hardness changes during a collision and stipulation of criteria for particle fracture and cold welding. These provide a“snapshot” of that which transpires during a single collision event. The model also accounts for the heterogeneity of deformation within the powder trapped between colliding media. This heterogeneity, together with the model criteria, can then be incorporated within a computational scheme capable of predictive description of the evolution of powder morphology and properties during mechanical alloying, as will be described in a subsequent article.

TL;DR: In this article, positive matrix factorization (PMF) was applied to air quality and temperature data collected as part of the Program for Research on Oxidants: Photochemistry, Emissions, and Transport 1997 summer measurement campaign.
Abstract: Positive matrix factorization (PMF) was applied to air quality and temperature data collected as part of the Program for Research on Oxidants: Photochemistry, Emissions, and Transport 1997 summer measurement campaign. Unlike more conventional methods of factor analysis such as principal component analysis, PMF produces non-negative factors, aiding factor interpretation, and utilizes error estimates of the data matrix. This work uses PMF as a means of source identification and apportionment, important steps in the development of air pollution control strategies. Measurements of carbon monoxide, particulate matter, peroxyactyl nitrate (PAN), isoprene, temperature, and ozone were taken from a 31 m tower in rural northern Michigan and analyzed in this study. PMF resulted in three physically interpretable factors: an isoprene-dominated factor, a local source factor, and a long-range transport factor. The isoprene-dominated and local source factors exhibited strong and weak diurnal signals, respectively. Fact...

Journal ArticleDOI
TL;DR: In this article, the formation and stability of dislocation patterns are interpreted on the basis of instabilities occurring in partial differential equations modelling the dynamics of dislocations species under certain circumstances, these equations are shown to be a coupled system of the diffusion reaction type for the densities of immobile and mobile dislocation populations.
