226 Chatterjee, DeenDemocracy beyond borders: justice and representation in global institutionsA book review of Andrew Kuper's Democracy Beyond Borders: Justice and Representation in Global Institutions.Book review; Democracy; Global governance2006-04
227 Khan, Faisal HabibDeriving new topologies of DC-DC converters featuring basic switching cellsThis paper will introduce the two basic switching cells, P-cell and N-cell, and their applications in different power electronic circuits. These basic cells have one switching element and one diode. The P-cell is the mirror circuit of the N-cell and vice-versa, and this paper suggests that any powe...DC-DC converters; P-cell; N-cell; Switching cells; Cúk converters2006-07
228 Harrison, Reid R.Design and implementation of multipattern generators in analog VLSIIn recent years, computational biologists have shown through simulation that small neural networks with fixed connectivity are capable of producing multiple output rhythms in response to transient inputs. It is believed that such networks may play a key role in certain biological behaviors such as d...2006-07
229 Liu, FengDetermination of the Ehrlich-Schwoebel barrier in epitaxial growth of thin filmsWe demonstrate an approach for determining the "effective" Ehrlich-Schwoebel (ES) step-edge barrier, an important kinetic constant to control the interlayer mass transport in epitaxial growth of thin films. The approach exploits the rate difference between the growth and/or decay of an adatom and a...Ehrlich-Schwoebel barrier; Epitaxial growth; Step-edge barrier; Adatoms2006-11
230 Zimmer, ZacharyDisability and active life expectancy among older CambodiansOlder adults in Cambodia are survivors of harsh living conditions, including poverty and periods of extreme violence. Although these experiences may affect health outcomes, little data has existed to monitor Cambodia's older population. The current paper uses data from the 2004 Study of the Elder...Active life expectancy; ageing; Cambodia; disability; functional status; Southeast Asia2006-07
231 Nichols, ShaunDo children think of the self as the soul?Bering's work provides new insight into the child's concept of the self. For his results indicate that children don't regard bodily identity as required for identity of self across time. Bering's methodology for investigating afterlife beliefs might also be exploited to explore the extent to which c...2006-10
232 Gondolo, PaoloEffect of a late decaying scalar on the neutralino relic densityIf the energy density of the Universe before nucleosynthesis is dominated by a scalar field Ø that decays and reheats the plasma to a temperature TRH smaller than the standard neutralino freeze-out temperature, the neutralino relic density differs from its standard value. In this case, the relic de...Neutralinos; Relic density; Reheating temperature2006-10
233 Mishchenko, Eugene; Raikh, Mikhail E.Electrostatics of straight and bent single-walled carbon nanotubesResponse of a single-walled carbon nanotube to external electric field, F, is calculated analytically within the classical electrostatics. Field-induced charge density distribution is approximately linear along the axis of a metallic nanotube and depends rather weakly, as ln(h/ r), on the nanotube...Electrostatics2006-10
234 Lupton, John MarkEvidence for temperature-independent triplet diffusion in a ladder-type conjugated polymerWe study the temperature dependence of triplet formation and decay by considering the phosphorescence dynamics in a prototypical conjugated polymer matrix. The dynamics of triplet formation as a function of temperature are unraveled by applying an electric field during optical singlet generation a...Triplet diffusion; Triplet excitons; Ladder-type conjugated polymers; Temperature dependence2006-12
235 Zhdanov, Michael S.Fast numerical modeling of multitransmitter electromagnetic data using multigrid quasi-linear approximationMultitransmitter electromagnetic (EM) surveys are widely used in remote-sensing and geophysical exploration. The interpretation of the multitransmitter geophysical data requires numerous three-dimensional (3-D) modelings of the responses of the receivers for different geoelectrical models of comple...multitransmitter electromagnetic data; numerical modeling; multigrid quasi-linear approximation; quasilinear approximation; geophysical exploration; 3-D modeling2006-06
236 Varner, Michael W.Fetal injury associated with cesarean delivery.OBJECTIVE: To describe the incidence and type of fetal injury identified in women undergoing cesarean delivery. METHODS: Between January 1, 1999, and December 31, 2000, a prospective cohort study of all cesarean deliveries was conducted at 13 university centers. Information regarding maternal and in...Birth Injuries; Cesarean Section; Adverse Effects2006-10
237 Gerton, JordanFluorescence near-field microscopy of DNA at Sub-10A nm resolutionWe demonstrate apertureless near-field microscopy of single molecules at sub-10 nm resolution. With a novel phase filter, near-field images of single organic fluorophores were obtained with ~sixfold improvement in the signal-to-noise ratio. The improvement allowed pairs of molecules separated by ~...2006-12

239 Mishchenko, EugeneGapless surfaces in anisotropic superfluidsWe demonstrate when p-wave pairing occurs between species whose free Fermi surfaces are mismatched the gap generally vanishes over a two-dimensional surface. We present detailed calculations of condensation energy, superfluid density (Meissner mass) and specific heat for such states. We also consi...Anisotropic superfluids; Meissner mass2006-11
240 Wu, Yong-ShiGeneral theorem relating the bulk topological number to edge states in two-dimensional insulatorsWe prove a general theorem on the relation between the bulk topological quantum number and the edge states in two-dimensional insulators. It is shown that whenever there is a topological order in bulk, characterized by a nonvanishing Chern number, even if it is defined for a nonconserved quantity s...Edge states; Bulk topology; Chern number2006-07
241 Mishchenko, EugeneGeneration of spin current by Coulomb dragCoulomb drag between two quantum wires is exponentially sensitive to the mismatch of their electronic densities. The application of a magnetic field can compensate this mismatch for electrons of opposite spin directions in different wires. The resulting enhanced momentum transfer leads to the conv...Spin current; Coulomb drag; Quantum wires2006-12

243 Zimmer, ZacharyImpact of past conflicts and social disruption on the elderly in CambodiaCambodia experienced violence during the rule of the Khmer Rouge in the 1970s. Many who died were the children or spouses of today's elderly. This may have resulted in an erosion of family support in a country where formal channels of assistance are virtually absent. This article examines the extent...Cambodia; Elderly; Social Disruption; Conflicts; Poverty2006-06
244 Liu, FengInfluence of quantum size effects on Pb island growth and diffusion barrier oscillationsQuantum size effects are successfully exploited in manipulating the growth of (111) oriented Pb islands on Si(111) substrate with a scanning tunneling microscope.

246 Hansen, Charles D.Interactive display of isosurfaces with global illuminationAbstract-In many applications, volumetric data sets are examined by displaying isosurfaces, surfaces where the data, or some function of the data, takes on a given value.
