Unfitted Nitsche's method for computing band structures in phononic crystals with impurities

Subjects: subject: Numerical Analysis (math.NA)

description: In this paper, we propose an unfitted Nitsche's method to compute the band structures of phononic crystal with impurities of general geometry. The proposed method does not require the background mesh to fit the interfaces of impurities, and thus avoids the expensive cost of generating body-fitted meshes and simplifies the inclusion of interface conditions in the formulation. The quasi-periodic boundary conditions are handled by the Floquet-Bloch transform, which converts the computation of band structures into an eigenvalue problem with periodic boundary conditions. More importantly, we show the well-posedness of the proposed method using a delicate argument based on the trace inequality, and further prove the convergence by the Babuška-Osborn theory. We achieve the optimal convergence rate at the presence of the impurities of general geometry. We confirm the theoretical results by two numerical examples, and show the capability of the proposed methods for computing the band structures without fitting the interfaces of impurities.

description: We study phenomenological predictions in the scenario with the quasi-degenerate relation among neutrino Dirac masses, m_D1 simeq m_D2 < m_D3, assuming the bi-maximal mixing at the grand unification scale in supersymmetric standard models with right-handed neutrinos. A sufficient lepton number asymmetry can be produced for successful leptogenesis. The lepton flavor violating process mu to e gamma can be enhanced due to the Majorana phase, so that it can be detectable at forthcoming experiments. The processes tau to e gamma and tau to mu gamma are suppressed because of the structure of neutrino Dirac masses, and their branching ratios are smaller than that of mu to e gamma.

description: This paper outlines my analysis of health and mortality in Pennsylvania jails using publicly available datasets from the Pennsylvania Department of Corrections, US Census, and Centers for Disease Control and Prevention. I explored jail data from the Pennsylvania DOC, showing a chronic overcrowding problem in several jails and highlighting concerns about data on mental health hospitalizations, population flow, and sentencing status. My primary focus was mortality; this research revealed that suicides are an enormous health problem in jails. Nearly forty percent of deaths in Pennsylvania jail from 2015 to 2018 were suicides. A novel analysis suggests that the jail suicide rate is more than twice that of similar people in the resident Pennsylvania population. Further, I cleaned, standardized and combined several datasets, so that my colleagues at CHRS can continue further investigations on this topic.

description: The transverse momentum spectra of identified charged particles have been measured at very low and intermediate transverse momenta in Au+Au collisions at sqrt(s_NN) = 62.4 GeV and d+Au collisions at sqrt(s_NN) = 200 GeV using the PHOBOS detector at RHIC. New results on charged particle production at very low p_T in central Au+Au collisions at sqrt(s_{NN) = 200 GeV in the centrality intervals 0-6% and 6-15% are presented. A comparison of the PHOBOS low-p_T data with predictions of a recent optical model is shown. The shapes of m_T spectra for d+Au and Au+Au collisions are compared.

description: A great deal of time and effort has been dedicated to entrepreneurship research regarding the characteristics of entrepreneurs. However, characteristics of entrepreneurs in the gestation period have received less attention due to the difficulty of obtaining data from potential entrepreneurs at this stage in the entrepreneurial process. The purpose of this study is twofold. First we review the literature to determine key characteristics of entrepreneurs. Then utilizing a sample of Indiana entrepreneurs in the gestation stage, we conduct an empirical analysis. In addition to the key components identified through the literature review, in the empirical analysis additional variables are considered that we believe will be major determinants of business start-up.

description: This report analyzes results of a variable rate manure trial designed to test the potential of site-specific manure (SSM) management. To estimate corn and soybean response to manure, a system of equations estimated with three stage least squares (3SLS) including continuous soil test information as well as discrete management zones is proposed. Net present values (NPV) over a corn and soybean growing cycle were highest for whole-field manure management strategy combined with a variable rate fertilizer (VRF) phosphorous, potassium, and lime program (WFM-VRF), followed by a variable rate manure (VRM) management strategy combined with a VRF program. The third best strategy is a WFM-VRF strategy following an extension recommendation rate of 3500 gallons (gal) acre-1 of applied manure. The VRM strategies may have environmental benefits because they result in the lower average manure loadings than either following extension recommendations or developing a field specific uniform rate plan. If higher manure loadings are environmentally acceptable, then the WFM-VRF strategy is an attractive alternative.

Accretion Disc Structure and Orientation in the Lensed and Microlensed Q0957+561 Quasar

Year: 2005

description: Because quasars are unresolved in optical imaging, their structures must presently be inferred. Gravitational microlensing offers the possibility to produce information about the luminous structure provided the Einstein ring diameter of the microlensing particle is comparable to or smaller than the radiating quasar components. The long brightness history measured for the Q0957 quasar has been analyzed previously for information about the microlensing particles, and evidence for the existence of a cosmologically significant population of planetary mass particles has been reported. The microlensing results have also directly determined the sizes of the ultraviolet light emitting surfaces in the quasar Autocorrelation analysis of the same brightness record has produced evidence for complex structure in the quasar; if the quasar suddenly brightens today, it is probable that it will brighten again after 129, 190, 540, and 620 days. We interpret these lags as the result of luminous structure around the quasar, and in particular we interpret them in the context of the Elvis (2000) model of the quasar's structure. We find that the autocorrelation peaks imply that beyond the luminous inner edge of the accretion disc, the biconic structures of the Elvis model must lie at a radial distance of 2x10^17 cm from the black hole, and 2x10^16 cm above and below the plane of the accretion disc. The quasar is apparently inclined 55 degrees to the line of sight. A second possible solution with lower inclination and larger structure is also indicated but statistically less probable.

A finite-difference scheme for three-dimensional incompressible flows in spherical coordinates

description: In this study we have developed a flexible and efficient numerical scheme for the simulation of three-dimensional incompressible flows in spherical coordinates. The main idea, inspired by a similar strategy as (Verzicco, R., Orlandi, P., 1996, A Finite-Difference Scheme for Three-Dimensional Incompressible Flows in Cylindrical Coordinates) for cylindrical coordinates, consists of a change of variables combined with a discretization on a staggered mesh and the special treatment of few discrete terms that remove the singularities of the Navier-Stokes equations at the sphere centre and along the polar axis. This new method alleviates also the time step restrictions introduced by the discretization around the polar axis while the sphere centre still yields strong limitations, although only in very unfavourable flow configurations. The scheme is second-order accurate in space and is verified and validated by computing numerical examples that are compared with similar results produced by other codes or available from the literature. The method can cope with flows evolving in the whole sphere, in a spherical shell and in a sector without any change and, thanks to the flexibility of finite-differences, it can employ generic mesh stretching (in two of the three directions) and complex boundary conditions.

description: This teaching note accompanies the case study "Which Way to Grow at MBC Farms?" The case was published in the Review of Agricultural Economics, Volume 26, Number 4, 2004. Like many farm operations, MBC Farms is trying to determine what strategic actions to take to remain competitive. The farm produces corn and soybeans, contracted specialty corn, and milk. The crops and dairy managers are considering growth opportunities, but have not decided on a strategy. There are a number of possibilities, but the management team is seriously considering expanding either the dairy to take advantage of a milk contract or contract crop production. With the MBC Farms case, instructors can teach farm business managers how to use strategic and financial planning tools to select a growth path for the firm.

Massive elliptical galaxies : From cores to haloes

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: In the context of recent observational results that show massive ellipticals were in place at high redshifts, we reassess the status of monolithic collapse in a LCDM universe. Using a sample of over 2000 galaxies from the Sloan Digital Sky Survey, by comparing the dynamical mass and stellar mass (estimated from colours) we find that ellipticals have `cores' which are baryon-dominated within their half-light radius. These galaxies correspond to 3-sigma peaks in the spherical collapse model if the total mass in the halo is assumed to be 20 times the dynamical mass within the half-light radius. This value yields stellar mass to total mass ratios of 8%, compared to a cosmological baryon fraction of 18% derived from WMAP3 alone. We further develop a method for reconstructing the concentration halo parameter c of the progenitors of these galaxies by utilizing adiabatic contraction. Although the analysis is done within the framework of monolithic collapse, the resulting distribution of c is log-normal with a peak value of c~3-10 and a distribution width similar to the results of N-body simulations. We also derive scaling relations between stellar and dynamical mass and the velocity dispersion, and find that these are sufficient to recover the tilt of the fundamental plane.

The effects of curvature on the propagation of undulatory waves in lower dimensional elastic materials

Year: 2020

description: The mechanics of lower dimensional elastic structures depends strongly on the geometry of their stress-free state. Elastic deformations separate into in-plane stretching and lower energy out-of-plane bending deformations. For elastic structures with a curved stress-free state, these two elastic modes are coupled within linear elasticity. We investigate the effect of that curvature-induced coupling on wave propagation in lower dimensional elastic structures, focusing on the simplest example -- a curved elastic rod. We find that the dispersion relation of the waves becomes gapped in the presence of finite curvature; bending modes are absent below a frequency proportional to the curvature of the rod. By studying the scattering of undulatory waves off regions of uniform curvature, we find that undulatory waves with frequencies in the gap associated with the curved region tunnel through that curved region via conversion into compression waves. These results should be directly applicable to the spectrum and spatial distribution of phonon modes in a number of curved rod-like elastic solids, including carbon nanotubes and biopolymer filaments.

description: Mathematical measures of entropy as defined by Shannon (1948) and Kullback and Leibler (1951) are currently in vogue in the field of econometrics, primarily due to the comprehensive work by Golan, Judge, and Miller (1996). In this paper, an alternative interpretation of the entropy measure as a penalty function over deviations is presented. Using this interpretation, a number of parallels are drawn with least squares estimators, and it is demonstrated that, with a minor modification of the traditional least squares estimator, both approaches may be applied to the general linear model. The advantages and disadvantages of each approach are discussed, and a philosophical approach to the selection of estimation technique is suggested.
Can Recently Derived Solar Photospheric Abundances Be Consistent with Helioseismology?
Creators: name: Guzik, J.

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recent solar abundance analyses (Asplund et al. 2004; Lodders 2003) revise downward the abundances of C, N, O, Ne, and Ar, which reduces the solar photospheric Z/X to 0.017, and Z to ~0.013. Solar models evolved with standard opacities and diffusion treatment using these new abundances give poor agreement with helioseismic inferences for sound speed profile, convection zone helium abundance, and convection zone depth. Here we present helioseismic results for evolved solar models with these reduced photospheric abundances, trying varying diffusion treatments. We compare results for models with no diffusion, enhanced thermal diffusion, and enhanced diffusion of C, N, O, Ne, and Mg only. We find that while each of these models provides some improvements compared to a solar model evolved with the new abundances and standard physics, none restores the good agreement with helioseismology attained using the earlier abundances of, e.g., Grevesse & Sauval (1998). We suggest that opacity increases of about 20% for conditions below the convection zone, or the possibility of accretion of lower-Z material at the surface as the sun arrived at the main sequence, should be investigated to restore agreement. In addition, the new abundance determinations should be re-considered, as, if they are correct, it will be difficult to reconcile solar models with helioseismic results.

description: The sum rule for the structure function $g_1^{p}$ which is related to the cross section of the photo-production is used to show that a sign change of the integral corresponding to the appropriately defined moment at $n=0$ where the integral is cut at the point $x=x_c(Q^2)$ occurs at very small $Q^2$ near $Q^2\sim 0.09$(GeV/c)$^2$ and $x_c\sim 0.024$. This fact shows that the origin of the sign difference between the Ellis-Jaffe sum rule and the Drell-Hearn-Gerasimov sum rule lies in the rapid change of the elastic contribution at low $Q^2$ which is compensated by the inelastic contribution to satisfy the sum rule at $n=0$. Hence it occurs at very small $Q^2$.

description: This study demonstrates multilevel switching at 1.5 K of Al2O3/TiO2-x resistive memory devices fabricated with CMOS-compatible processes and materials. The I-V characteristics exhibit a negative differential resistance (NDR) effect due to a Joule-heating-induced metal-insulator transition of the Ti4O7 conductive filament. Carrier transport analysis of all multilevel switching I-V curves show that while the insulating regime follows the space charge limited current (SCLC) model for all resistance states, the conduction in the metallic regime is dominated by SCLC and trap-assisted tunneling (TAT) for low- and high-resistance states respectively. A non-monotonic conductance evolution is observed in the insulating regime, as opposed to the continuous and gradual conductance increase and decrease obtained in the metallic regime during the multilevel SET and RESET operations. Cryogenic transport analysis coupled to an analytical model accounting for the metal-insulator-transition-induced NDR effects and the resistance states of the device provide new insights on the conductive filament evolution dynamics and resistive switching mechanisms. Our findings suggest that the non-monotonic conductance evolution in the insulating regime is due to the combined effects of longitudinal and radial variations of the Ti4O7 conductive filament during the switching. This behavior results from the interplay between temperature- and field-dependent geometrical and physical characteristics of the filament.

description: The impact of identity preservation (IP) for genetically modified grains (GMOs) on the grain handling system for a typical region in the Eastern Corn Belt is examined. A cost minimizing linear programming model of the transshipment system from farms to grain elevators to grain users tracks shipments and costs through the marketing system. This study compares two different grain segregation strategies: segregating grain within the elevator and designating specific elevators as IP-only facilities. As the cost per unit for grain segregation increases, the designated plant strategy becomes the most cost efficient strategy.

description: We analyzed RXTE archival observations of 4U 1907+09 between 17 February 1996 and 6 March 2002. The pulse timing analysis showed that the source stayed at almost {\bf{constant}} period around August 1998 and then started to spin-down at a rate of $(-1.887\mp 0.042)\times 10^{-14}$ Hz s$^-1$ which is $\sim$ 0.60 times lower than the long term ($\sim 15$ years) spin-down rate (Baykal et al. 2001). Our pulse frequency measurements for the first time resolved significant spin-down rate variations since the discovery of the source. We also presented orbital phase resolved X-ray spectra during two stable spin down episodes during November 1996 - December 1997 and March 2001 - March 2002. The source has been known to have two orbitally locked flares. We found that X-ray flux and spectral parameters except Hydrogen column density agreed with each other during the flares.We interpreted the similar values of X-ray fluxes as an indication of the fact that the source accretes not only via transient retrograde accretion disc (in't Zand et al. 1998) but also via the stellar wind of the companion (Roberts et al. 2001), so that the variation of the accretion rate from the disc does not cause significant variation in the observed X-ray flux. Lack of significant change in spectral parameters except Hydrogen column density was interpreted as a sign of the fact that the change in the spin-down rate of the source was not accompanied by a significant variation in the accretion geometry.

ESL students learning biology : the role of language and social interactions
Creators: name: Jaipal, Kamini
Publisher: name: University of British Columbia
Year: 2009

description: This study explored three aspects related to ESL students in a mainstream grade 11 biology classroom: 1) the nature of students' participation in classroom activities, 2) the factors that enhanced or constrained ESL students' engagement in social interactions, and 3) the role of language in the learning of science. Ten ESL students were observed over an eight-month period in this biology classroom. Data were collected using qualitative research methods such as participant observation, audio-recordings of lessons, field notes, semi-structured interviews, short lesson recall interviews and students' written work. The study was framed within sociocultural perspectives, particularly the social constructivist perspectives of Vygotsky (1962,1978) and Wertsch (1991). Data were analysed with respect to the three research aspects. Firstly, the findings showed that ESL students' preferred and exhibited a variety of participation practices that ranged from personal-individual to socio-interactive in nature. Both personal-individual and socio-interactive practices appeared to support science and language learning. Secondly, the findings indicated that ESL students' engagement in classroom social interactions was most likely influenced by the complex interactions between a number of competing factors at the individual, interpersonal and community/cultural levels (Rogoff, Radziszewska, & Masiello, 1995). In this study, six factors that appeared to enhance or constrain ESL students' engagement in classroom social interactions were identified. These factors were socio-cultural factors, prior classroom practice, teaching practices, affective factors, English language proficiency, and participation in the research project. Thirdly, the findings indicated that language played a significant mediational role in ESL students' learning of science. The data revealed that the learning of science terms and concepts can be explained by a functional model of language that includes: 1) the use of discourse to construct meanings, 2) multiple semiotic representations of the thing/process, and 3) constructing taxonomies and ways of reasoning. Other important findings were: talking about language is integral to biology teaching and learning, ESL students' prior knowledge of everyday words does not necessarily help them interpret written questions on worksheets, and ESL students' prior knowledge of concepts in their first language does not necessarily support concept learning in the second language.

description: Excerpts from the report: Marketing the products of the Nation's farms, ranches, and groves requires the physical handling and the movement of millions of tons of commodities each year. Some of these products are handled as many as 25 or 30 times between producer and consumer. These operations require thousands of workers and millions of man-hours of labor. Currently the labor required for marketing some products exceeds that necessary to produce them. This emphasizes the importance of the efficient use of manpower. This report is one of a series designed to guide operators of apple and other fruit packing and storage houses in reducing labor required for various physical handling and warehouse operations. It outlines some of the methods by which labor can be made more productive. Although it evaluates methods and equipment used for handling boxes of apples in Pacific Northwest apple houses and appraises some of the methods and equipment developed during the research in that area, the results should be applicable to commercial fruit packing and storage houses in all areas.

description: An eleven-region stochastic coefficient econometric model was estimated and used in an optimal control framework to evaluate the effectiveness of the dairy price support program and marketing orders in reducing and stabilizing government purchases of dairy products. The results showed significant pressure on the reduction of the support price both in the presence and absence of Class I differentials. The optimal control model also showed that the drop in price support levels did not dramatically alter the regional distribution of milk production.

description: Methyl parathion or Penncap M (an encapsulated methyl parathion) are used extensively throughout the United States for controlling stink bug pests in soybeans, Glycine Max (L.) Merrill. However, this insecticide is highly toxic to mammals, birds, and non-target arthropods, and thus is less environmentally sound than other insecticides. For environmental and human health considerations, investigating alternative insecticides for control is desired. For this investigation, research based on field experimental data from Florida, Georgia, and Louisiana during the 1988 and 1989 growing seasons were employed. Results indicate that alternative, currently available, and less toxic insecticides may reduce producer costs, increase yield, and improve soybean quality. These alternative insecticides include Scout (tralomethrin), Karate (lambda-cyhalothrin), Orthene (acephate), and Baythroid (cyfluthrin). In terms of improved profits these alternative insecticides may dominate methyl parathion or encapsulated methyl parathion.

description: The rate of noise-induced escape from a metastable state of a periodically modulated overdamped system is found for an arbitrary modulation amplitude $A$. The instantaneous escape rate displays peaks that vary with the modulation from Gaussian to strongly asymmetric. The prefactor $ν$ in the period-averaged escape rate depends on $A$ nonmonotonically. Near the bifurcation amplitude $A_c$ it scales as $ν\propto (A_c-A)^ζ$. We identify three scaling regimes, with $ζ= 1/4, -1$, and 1/2.

description: We study the lepton-jet correlation in deep inelastic scattering. We perform one-loop calculations for the spin averaged and transverse spin dependent differential cross sections depending on the total transverse momentum of the final state lepton and the jet. The transverse momentum dependent (TMD) factorization formalism is applied to describe the relevant observables. To show the physics reach of this process, we perform a phenomenological study for HERA kinematics and comment on an ongoing analysis of experimental data. In addition, we highlight the potential of this process to constrain small-$x$ dynamics.

description: A model of the political economy of agricultural policy formulation was used to analyze the current stalemate in the Uruguay Round of Multilateral Trade Negotiations. The combination of social welfare increasing and transferring policies in the European Community and the U.S. is one of the primary causes of the deadlock in trade negotiations. The Community's farm policy of high internal price supports, limited market access, and export subsidies represents short-term equilibria in the market for social-welfare policies which distribute benefits to producers at the expense of consumers and taxpayers. Thus, the opportunity for internal reform of the CAP leading to a compromise in the GATT negotiations is problematic at best. However, international commitments to agricultural policy reform will force the Community to make concessions which will bring equivalent change in domestic policy.

description: This article investigates a set of partial differential equations, the DT-instanton equations, whose solutions can be regarded as a generalization of the notion of Hermitian-Yang-Mills connections. These equations owe their name to the hope that they may be useful in extending the DT-invariant to the case of symplectic 6-manifolds. In this article, we give the first examples of non-Abelian and irreducible DT-instantons on non-Kähler manifolds. These are constructed for all homogeneous almost Hermitian structures on the manifold of full flags in $\mathbb{C}^3$. Together with the existence result we derive a very explicit classification of homogeneous DT-instantons for such structures. Using this classification we are able to observe phenomena where, by varying the underlying almost Hermitian structure, an irreducible DT-instanton becomes reducible and then disappears. This is a non-Kähler analogue of passing a stability wall, which in string theory can be interpreted as supersymmetry breaking by internal gauge fields.

description: The electron scattering from periodic line defects on the surface of topological insulators with hexagonal warping effect is investigated theoretically by means of a transfer matrix method. The influence of surface line defects, acting as structural ripples on propagation of electrons are studied in two perpendicular directions due to the asymmetry of warped energy contour under momentum exchange. The transmission profiles and the details of resonant peaks which vary with the number of defects and the strength of their potentials are strongly dependent on the direction in which the line defects extend. At low energies, the quantum interference between the incident and reflected propagating electrons has the dominant contribution in transmission resonances, while at high energies the multiple scattering processes on the constant-energy contour also appear because of the strong warping effect. By increasing the spatial separation between the line defects, the minimum value of electrical conductance remains significantly high at low incident energies, while the minimum value may approach zero at high energies as the number of defects is increased. Our findings suggest that the potential ripples on the surface of topological insulators can be utilized to control the local electronic properties of these materials.

description: Stochastic simulation was used to analyze revenues and costs for a small-scale catfish processing plant under various combinations of operating capacity utilization and price paid for live fish. The probability for a positive level of daily net income ranged from 11 to 100 percent depending on the price paid for live fish and level of operating capacity utilized. Daily average total cost per pound of live fish processed changed by 2.10 percent given a 10 percent change in live fish processed. Short-term cyclical patterns in revenues and costs suggest a need for financial planning to provide for possible year-end revenue shortfalls.

description: In a recent Letter the phase diagram of Co/Cu/Ni/Cu(100) and Co/Fe/Ni/Cu(100) trilayers was determined experimentally as well as theoretically. Whereas we do not object the presented results, we remark that published work was not commented on. Especially, much more information can be extracted out of the measurements by a quantitative comparison with an appropriate model, allowing for a determination of important parameters such as exchange coupling constants.

description: This paper mainly focuses on environment perception in snowy situations which forms the backbone of the autonomous driving technology. For the purpose, semantic segmentation is employed to classify the objects while the vehicle is driven autonomously. We train the Fully Convolutional Networks (FCN) on our own dataset and present the experimental results. Finally, the outcomes are analyzed to give a conclusion. It can be concluded that the database still needs to be optimized and a favorable algorithm should be proposed to get better results.

description: The 1990 Farm Bill contains several measures concerning soil erosion caused by U.S. farmers. Data from a nationwide survey of people concerning their attitudes toward agriculture were used to examine the structure of respondents' preferences for government support-policies to combat soil erosion. Estimates of the influence of socio-economic and demographic variables on policy preferences were computed using a multiple-indicator model. Results show more support for the regulation of soil erosion, including laws and fines, than for government financial support.
The Geometric Calibration of the Planck satellite using point-source observations

description: The geometric calibration of the Planck satellite is investigated, specifically those parameters which require the use of the science data for their extraction. Methods for the recovery of these geometric-calibration parameters from point source detections in the science data are presented, together with the accuracies which may be achieved. These methods apply to the a posteriori evaluation of these parameters using all the mission data, and may be incorporated into the initial stages of the construction of the Planck final compact source catalogue. It is found that this process achieves the pointing requirements, provided that the geometric-calibration parameters vary only slowly in time. Indeed the errors in the pointing reconstruction due to the geometric calibration parameters may be seen to approach those due to the star tracker.

description: In this paper we define a way to get a bounded invertible automaton starting from a finite graph. It turns out that the corresponding automaton group is regular weakly branch over its commutator subgroup, contains a free semigroup on two elements and is amenable of exponential growth. We also highlight a connection between our construction and the right-angled Artin groups. We then study the Schreier graphs associated with the self-similar action of these automaton groups on the regular rooted tree. We explicitly determine their diameter and their automorphism group in the case where the initial graph is a path. Moreover, we show that the case of cycles gives rise to Schreier graphs whose automorphism group is isomorphic to the dihedral group. It is remarkable that our construction recovers some classical examples of automaton groups like the Adding machine and the Tangled odometer.

description: This study examined the supply of and demand for married female labor in the southern United States. Special attention was given to differences in labor force participation, labor supply, and quantities of labor supplied and demanded across rural and urban areas. Once state effects were accounted for, decisions to change participation were found not to vary by urban-rural designation. Differences in demand were fully captured by an intercept shifter and the variations in hours supplied by married females between urban and rural areas. Labor supply varied greatly with the effects of key determinants (number of children, work force experience, family income) being strongly different in rural areas. Different policies are needed to promote female labor supply in rural areas as opposed to urban areas.
Classical Electromagnetism as a Consequence of Coulomb's Law, Special Relativity and Hamilton's Principle and its Relationship to Quantum Electrodynamics

description: It is demonstrated how all the mechanical equations of classical electrodynamics (CEM) may be derived from only Coulomb's inverse square force law, special relativity and Hamilton's Principle. The instantaneous nature of the Coulomb force in the centre-of-mass frame of two interacting charged objects, mediated by the exchange of space-like virtual photons, is predicted by QED. The interaction Lagrangian of QED is shown to be identical, in the appropriate limit, to the potential energy term in the Lorentz-invariant Lagrangian of CEM. A comparison is made with the Feynman-Wheeler action-at-a-distance formulation of CEM.
description: 32 pages, 2 figures. It is found that electromagnetic forces between two charged objects are transmitted instantaneously in their common C.M. frame.
