We study the states of one and two atoms in a rotating ring lattice in a Hubbard-type tight-binding model. The model is developed carefully from basic principles in order to properly identify the physical observables. The one-particle ground state may be degenerate and represent a finite flow velocity depending on the parity of the number of lattice sites, the sign of the tunneling matrix element, and the rotation speed of the lattice. Variation of the rotation speed may be used to control one-atom states and leads to peculiar behaviors such as wildly different phase and group velocities for an atom. Adiabatic variation of the rotation speed of the lattice may also be used to control the state of a two-atom lattice dimer. For instance, at a suitably chosen rotation speed both atoms are confined to the same lattice site. © 2012 American Physical Society.

Journal of Homosexuality | Year: 2014

The present research investigated how personal beliefs about homosexuality influence learning in a college course. We tested students in introductory psychology over material on the science of homosexuality by Simon LeVay (2010). All students reported information about their typical academic habits and the extent to which homosexuality was consistent with their beliefs and values. The results showed that students' personal beliefs were related to academic behaviors (e.g., reading assignments, skipping class) and retention of the course material. The results also showed that students' recall of course material six weeks later was predicted by the extent to which they reported studying information that is inconsistent with their beliefs for an exam and then forgetting it. Students who reported the material to be inconsistent with their beliefs engaged in selective forgetting of the material on homosexuality. The results provide evidence that personal beliefs can reduce the retention of belief-inconsistent information in a college course. © Taylor & Francis Group, LLC.

Electrical, thermal and thermoelectric properties of chemically synthesized polyanilines (PANI)/metallic silver composites are reported and discussed in regard to their morphological features as determined by SEM. The metal-intrinsic conducting polymer power factor (PF) and figure of merit (ZT) are deduced from measurements of the electrical conductivity (σ), Seebeck coefficient (S), thermal diffusivity (α), thermal effusivity (e) and thermal conductivity (κ). It is shown that the PANI/Ag thermoelectric (TE) characteristics are much more improved as compared to those of pure PANI. In addition, the results reveal that the metal/PANI properties are inherently dependent on the volume concentration of silver and morphology of the composites. It is observed that electrical percolation takes place for samples having 16 vol% Ag content without any significant thermal percolation. The composite with 26 vol% Ag loading exhibits the best thermoelectric performance (PF ≈ 3 μW m-1 K-2; ZT ≈ 0.5 10-3). The overall enhanced TE performance of the PANI/Ag composites is attributed to an improved electrical conductivity with a concomitant limitation in the rise of thermal transport via scattering. © 2014 Elsevier B.V.

Recent advances in nanostructured materials have spurred the development of improved thermoelectric (TE) devices. Performances of these systems are strongly linked to their thermal conductivities. Accurate measurement techniques of thermal parameters are therefore required to assess the efficiency of new thermoelectric materials. In this work, thermal parameters (thermal diffusivity, thermal conductivity, and thermal effusivity) of nanostructured thermoelectric composites based on oxidised or unoxidised carbon nanotubes at 6.6 wt. % mixed with doped nanofibrous polyaniline have been measured with a novel photothermal method called photothermoelectricity. The thermal parameters are obtained from analyses of the phase and amplitude of the thermoelectric signal generated by the sample when it is periodically heated by a laser beam. Figure of merits are calculated from these results which indicate that the best nanocomposite exhibits almost four order of magnitude improvement compared with that of the pure doped matrix at room temperature. © 2013 American Institute of Physics.

A long-standing question in bat biology is if the evolution of echolocation and flight are associated or if they evolved independently, and if so, which evolved first. We seek to use ontogeny as a surrogate for understanding linkages between flight evolution and echolocation in bats. To do this we quantify the onset of recognizable sonar calls in newborn Artibeus jamaicensis and the tempo of growth and development across several different postnatal flight stages. By dropping individuals from a perch beginning on day 1 postpartum, we recorded vocalizations and quantified their flight ability into five developmental stages (flop, flutter, flap, flight and adult). One-day-old individuals were capable of emitting sonar-like frequency-modulated (FM) calls during free-fall that were not significantly different from adult sonar calls in high and low frequency (kHz). However, bandwidth (kHz) did increase significantly with age as did sweep rate (kHzms-1), whereas call duration significantly decreased. Few bats older than 18 days emitted communication calls as they fell and measured parameters of communication calls did not change significantly with age. Our data support the hypothesis that communication and sonar calls are discrete and independently derived at birth and thus have different evolutionary pathways as well. © 2014 The Zoological Society of London.

We report on the fabrication of polyaniline (PANI)/carbon nanotube (CNT) nanohybrids using a novel approach of CNT-templated polymerization process. The physical properties of the nanohybrids can be tuned by keeping a constant amount of CNTs and changing their nature, i.e., using single-walled, multiple-walled, oxidized or unoxidized. SEM investigations evidenced fibrous morphology in all PANI/CNT hybrids with nanometer-sized diameters. Spectroscopic (UV-vis, IR and Raman) analyses of the nanocomposites evidenced good π-π interactions between PANI rings and CNTs. X-ray crystallography supports the presence of nanocrystalline domains at 2θ ∼6.5°. Electrical and thermoelectric properties of nanohybrids containing: (a) unoxidized MWNTs or (b) oxidized SWNTs or oxidized MWNTs are reported for the first time. In the series of samples studied, the PANI/unoxidized SWNTs provided the most promising electrical (conductivity: σ = 530 S cm -1) and thermoelectric characteristics (seebeck coefficient: S = 33 μV K -1 and power factor: PF = 0.6 μW m -1 K -2). © 2012 Elsevier B.V.

Polyanilines (PANI)/reduced graphene oxide (RGO) nanocomposites are chemically synthesized. Their structure and morphology are characterized by scanning and transmission electron microscopies, x-ray diffraction and Raman spectroscopy. In addition, the nanocomposites' electrical, thermal and thermoelectric (TE) transport characteristics are investigated as a function of RGO content. The power factor and figure of merit (ZT) of PANI/RGO hybrids are deduced from measurements of the electrical conductivity (σ), Seebeck coefficient (α) and thermal conductivity (κ). Experimental results reveal that the properties of PANI/RGO composites are inherently dependent on the volume fraction of RGO. It is observed that electrical percolation follows a 2D conduction process which takes place for samples having 0.099 vol% RGO content. Unlike electrical conductivity, the thermal conductivity of PANI/RGO increases only slightly with the RGO fraction and is successfully fitted using a modified MG-EMA model which provides an interfacial (PANI/RGO nanoplatelets) resistance (Rk) of 4.9 × 10-10 m2 K W-1. This low Rk value is attributed to good interactions between the planar geometry of RGO platelets and PANI aromatic rings through π-π stackings as evidenced by Raman spectroscopy and x-ray studies. Compared to that of pure PANI, the TE performance of PANI/RGO composites exhibits a ZT enhancement of two orders of magnitude. © 2014 IOP Publishing Ltd.

The recently introduced photothermoelectric (PTE) effect is proposed as an alternative for measuring dynamic thermal parameters of solid samples. The front PTE configuration, together with the thermal-wave resonator cavity method as a scanning procedure, was used to measure the value of thermal effusivity. The back PTE configuration, together with the chopping frequency of incident radiation as a scanning parameter, leads to the direct measurement of thermal diffusivity. A theory based on the above two detection configurations was developed and its application to solids, covering a large range of typical values of thermal parameters (aluminum and copper alloys, glass, teflon, polyethylene, LiTaO3), was described in order to demonstrate the suitability of the method. Experimental support for other well-known techniques (photopyroelectric and infrared lock-in thermography) has validated the results obtained with the novel method. © 2014 IOP Publishing Ltd.

Biological Invasions | Year: 2014

The plant trade provides a major mechanism for the long-distance dispersal of land snails, including slugs, which have low natural mobility. Whereas inspections at national borders intercept many in-coming snails, dispersal within countries is much less well regulated and documented. To investigate the role of plant nurseries as a source for the distribution of non-native invertebrates, particularly land snails, we surveyed snails in 28 nurseries in Oklahoma (United States) and compared our survey with similar surveys worldwide. We found 36 taxa, including 16 species not native to the region; 11 of these were new state records. Snail species richness increased with increasing outside area of snail-appropriate habitat, but not with enclosed greenhouse area. Species composition was similar among nurseries and Oklahoma nurseries shared several species with nurseries in Hawaii and Europe. Appropriate models for the dispersal of snails via plant nurseries are the transport hub model (snails moving as contaminants on plants coming into and leaving nurseries) and, for snail populations already established in nurseries, the stratified diffusion model (contamination of plants by snails within nurseries, followed by long-distance jumps as plants are sold and transported). Potted plants are portable habitats that protect snails from detection, pesticides and desiccation. Dispersing snails may survive in urban habitats, where mulching and watering may ameliorate hot, dry summers and cold winters. © 2013 Springer Science+Business Media Dordrecht.

A computer application was written to complete the task of contour reduction. The application was used to complete analyses of twentieth-century post-tonal works for solo flute. The methodology of Rob Schultz’s Contour Reduction Algorithm was chosen for implementation. While contour reduction is a useful analytical tool, it is a meticulous and time-consuming process. Computer implementation of this procedure produces quick and accurate results while reducing analyst fatigue and human error. Java computer programming language is used to create a contour reduction application. This implementation greatly reduces the time needed to analyze a melody. Computer programming is combined with music analysis to produce informed and expressive musical interpretations. © Springer International Publishing Switzerland 2015.
