description: This paper analyzes the ad hoc decision of three Asian countries to peg their currency to the U.S. dollar prior to the Asian crisis. It uses the Sjaastad model to estimate the optimal basket weights for Thailand, Korea, and Singapore. The analysis in this paper differs from the optimal basket research since we are not searching for an ad hoc optimal basket; rather, the basket is the solution to the problem. For Thailand and Korea, the correct weights of the dollar in the basket are estimated to be 44 and 65 percent, respectively, which differ significantly from the actual weight of 100 percent for the U.S. dollar in their currency basket prior to the 1997 Asian crisis. Singapore, with a weight of 85 percent for the U.S. currency, is closer to a dollar peg, and therefore was less affected by the large depreciation of the European currencies and the yen toward the dollar that occurred prior to the Asian exchange rate crisis. Besides the fact that Singapore had better economic fundamentals prior to the crisis, the fact that the optimal basket for that country is closer to a dollar peg is an additional reason why its economy was less severely hit by the crisis.

description: The high degree of economic integration has led to an increased degree of currency substitution in the EU countries, which could bring instability in national money demand functions while an EU-wide money demand function could be more stable. Currency substitution usually takes the form of cross border deposits (CBD), which are not included in the traditional monetary aggregates. Thus, extended monetary aggregates that include the relevant CBDs are defined in this study. In order to investigate the implications of currency substitution for the stability of the demand functions, the traditional and extended monetary aggregates for five EU countries are defined in addition to EU-wide monetary aggregates. The estimated EU-wide demand for extended money appears to be stable suggesting that there is scope for monetary policy at the European level. However, the stability of the area-wide aggregate has been impaired when the relevant CBDs are not included.

description: The EDELWEISS collaboration is searching for WIMP dark matter using natural Ge cryogenic detectors. The whole data set of the first phase of the experiment contains a fiducial exposure of 4.8 kg.day on Ge-73, the naturally present (7.8%), high-spin Ge isotope. The sensitivity of the experiment to the spin-dependent WIMP-nucleon interactions is evaluated using the model-independent framework proposed by Tovey et al.

description: We estimate in this paper the market risk implied by the prices of different options traded in the Brazilian stock market. The fundamental theory to handle this problem is the one implied by the Arrow-Debreu contingent claim concept. Using that theory, we are able to construct the term structure of market risk, and to obtain a surface that provides slices for a particular “volatility smile.” The methodology that we use follows the one proposed by Shimko (1993), which is able to calculate a non-lognormal probability density function (PDF) consistent with the volatility observed in a relatively small sample of option prices. This methodology goes beyond the one proposed originally by Black and Scholes (1973), since it does not require log-normality of the PDF nor that volatility remains constant.

description: The dream of machine learning in materials science is for a model to learn the underlying physics of an atomic system, allowing it to move beyond interpolation of the training set to the prediction of properties that were not present in the original training data. In addition to advances in machine learning architectures and training techniques, achieving this ambitious goal requires a method to convert a 3D atomic system into a feature representation that preserves rotational and translational symmetry, smoothness under small perturbations, and invariance under re-ordering. The atomic orbital wavelet scattering transform preserves these symmetries by construction, and has achieved great success as a featurization method for machine learning energy prediction. Both in small molecules and in the bulk amorphous $\text{Li}_α\text{Si}$ system, machine learning models using wavelet scattering coefficients as features have demonstrated a comparable accuracy to Density Functional Theory at a small fraction of the computational cost. In this work, we test the generalizability of our $\text{Li}_α\text{Si}$ energy predictor to properties that were not included in the training set, such as elastic constants and migration barriers. We demonstrate that statistical feature selection methods can reduce over-fitting and lead to remarkable accuracy in these extrapolation tasks.

description: The paper considers the use of directed acyclic graphs (DAGs), and their construction from observational data with PC-algorithm TETRAD II, in providing over-identifying restrictions on the innovations from a vector autoregression. Results from Sims’ 1986 model of the US economy are replicated and compared using these data-driven techniques. The directed graph results show Sims’ six-variable VAR is not rich enough to provide an unambiguous ordering at usual levels of statistical significance. A significance level in the neighborhood of 30 % is required to find a clear structural ordering. Although the DAG results are in agreement with Sims’ theory-based model for unemployment, differences are noted for the other five variables: income, money supply, price level, interest rates, and investment. Overall the DAG results are broadly consistent with a monetarist view with adaptive expectations and no hyperinflation.
Dynamical and photometric imprints of feedback processes on the early evolution of E/S0 galaxies

description: We show that the observed Velocity Dispersion Function of E/S0 galaxies matches strikingly well the distribution function of virial velocities of massive halos virializing at z > 1.5, as predicted by the standard hierarchical clustering scenario in a \LambdaCDM cosmology, for a constant ratio sigma/V_vir = 0.55 \pm 0.05, close to the value expected at virialization if it typically occurred at z > 3. This strongly suggests that dissipative processes and later merging events had little impact on the matter density profile. Adopting the above sigma/V_vir ratio, the observed relationships between photometric and dynamical properties which define the fundamental plane of elliptical galaxies, such as the luminosity-sigma (Faber-Jackson) and the luminosity-effective radius relations, as well as the M_BH-sigma relation, are nicely reproduced. Their shapes turn out to be determined by the mutual feedback of star-formation (and supernova explosions)and nuclear activity, along the lines discussed by Granato et al. (2004). To our knowledge, this is the first semi-analytic model for which simultaneous fits of the fundamental plane relations and of the epoch-dependent luminosity function of spheroidal galaxies have been presented.

description: Biofuels are increasingly being looked at to spur economic activity in the agricultural sector and to contribute to broader rural development goals while at the same time assisting in the reduction of harmful emissions created by burning petroleum-based fuels. Hence, biofuels appear to be a “win-win” technology that will contribute to achieving a number of important policy goals. As a result, governments around the world have become actively involved in the promotion of this new industry. The industry has expanded rapidly in the last few years but is still in a developmental stage. As the industry matures, biofuel producers will begin to see opportunities in international markets. Canada and the United States have considerable export potential due to their large supply of biomass and technological capacity to convert the biomass into biofuel. This article examines the potential trade issues that could arise when biofuels enter the international market. The issues examined include subsidization, the trade effects of using biotechnology in producing biofuels, market access and tariff classification, and potential technical barriers to trade related to product standards.

Modeling Nonlocal Electron-Phonon Coupling in Organic Crystals Using Interpolative Maps: The Spectroscopy of Crystalline Pentacene and 7,8,15,16-Tetraazaterrylene

description: Electron-phonon coupling plays a central role in the transport properties and photophysics of organic crystals. Successful models describing charge- and energy-transport in these systems routinely include these effects. Most models for describing photophysics, on the other hand, only incorporate local electron-phonon coupling to intramolecular vibrational modes, while nonlocal electron-phonon coupling is neglected. One might expect nonlocal coupling to have an important effect on the photophysics of organic crystals, because it gives rise to large fluctuation in the charge-transfer couplings, and charge-transfer couplings play an important role in the spectroscopy of many organic crystals. Here, we study the effects of nonlocal coupling on the absorption spectrum of crystalline pentacene and 7,8,15,16-tetraazaterrylene. To this end, we develop a new mixed quantum-classical approach for including nonlocal coupling into spectroscopic and transport models for organic crystals. Importantly, our approach does not assume that the nonlocal coupling is linear, in contrast to most modern charge-transport models. We find that the nonlocal coupling broadens the absorption spectrum non-uniformly across the absorption line shape. In pentacene, for example, our model predicts that the lower Davydov component broadens considerably more than the upper Davydov component, explaining the origin of this experimental observation for the first time. By studying a simple dimer model, we are able to attribute this selective broadening to correlations between the fluctuations of the charge-transfer couplings. Overall, our method incorporates nonlocal electron-phonon coupling into spectroscopic and transport models with computational efficiency, generalizability to a wide range of organic crystals, and without any assumption of linearity.

The Intrinsic Shape of Spiral Galaxies in the 2MASS Large Galaxy Atlas
Creators: name: Ryden, Barbara S.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The apparent shapes of spiral galaxies in the 2-Micron All Sky Survey Large Galaxy Atlas are used to constrain the intrinsic shape of their disks. When the distribution of apparent axis ratios is estimated using a nonparametric kernel method, the shape distribution is inconsistent with axisymmetry at the 90% confidence level in the B band and at the 99% confidence level in the K band. If spirals are subdivided by Hubble type, the late-type spirals (Sc and later) are consistent with axisymmetry, while the earlier spirals are strongly inconsistent with axisymmetry. The distribution of disk ellipticity can be fitted adequately with either a Gaussian or a lognormal distribution. The best fits for the late spirals imply a median ellipticity of epsilon = 0.07 in the B band and epsilon = 0.02 in the K band. For the earlier spirals, the best fits imply a median ellipticity of epsilon = 0.18 in the B band and epsilon = 0.30 in the K band. The observed scatter in the Tully-Fisher relation, for both late and early spirals, is consistent with the disk ellipticity measured in the B band. This indicates that excluding spirals of Hubble type earlier than Sc will reduce the intrinsic scatter in the Tully-Fisher relation used as a distance indicator.

description: We present the results of a nonrelativistic constituent quark model study of the semileptonic decays $Λ_b^0 \to Λ_c^+ l^- {\bar ν}_l$ and $Ξ_b^0 \to Ξ_c^+ l^- {\bar ν}_l$. We work on coordinate space, with baryon wave functions recently obtained from a variational approach based on heavy quark symmetry . We develop a novel expansion of the electroweak current operator, which supplemented with heavy quark effective theory constraints, allows us to predict the baryon form factors and the decay distributions for all $q^2$ (or equivalently $w$) values accessible in the physical decays. Our results for the partially integrated longitudinal and transverse decay widths, in the vicinity of the $w=1$ point, are in excellent agreement with lattice calculations. Comparison of our integrated $Λ_b-$decay width to experiment allows us to extract the $V_{cb}$ Cabbibo-Kobayashi-Maskawa matrix element for which we obtain a value of $|V_{cb}| = 0.040\pm 0.005 ({\rm stat}) ^{+0.001}_{-0.002} ({\rm theory})$ also in excellent agreement with a recent determination by the DELPHI Collaboration from the exclusive ${\bar {\rm B}^0_{\rm d}} \to {\rm D}^{*+}l^-{\bar ν}_l$ decay. Besides for the $Λ_b (Ξ_b)-$decay, the longitudinal and transverse asymmetries, and the longitudinal to transverse decay ratio are $=-0.954\pm 0.001 (-0.945\pm 0.002)$, $=-0.665\pm 0.002 (-0.628\pm 0.004)$ and $R_{L/T}=1.63\pm 0.02 (1.53\pm 0.04)$, respectively.

description: We present an overview of the CMZoom survey and its first data release. CMZoom is the first blind, high-resolution survey of the Central Molecular Zone (CMZ; the inner 500 pc of the Milky Way) at wavelengths sensitive to the pre-cursors of high-mass stars. CMZoom is a 500-hour Large Program on the Submillimeter Array (SMA) that mapped at 1.3 mm all of the gas and dust in the CMZ above a molecular hydrogen column density of 10^23 cm^-2 at a resolution of ~3" (0.1 pc). In this paper, we focus on the 1.3 mm dust continuum and its data release, but also describe CMZoom spectral line data which will be released in a forthcoming publication. While CMZoom detected many regions with rich and complex substructure, its key result is an overall deficit in compact substructures on 0.1 - 2 pc scales (the compact dense gas fraction: CDGF). In comparison with clouds in the Galactic disk, the CDGF in the CMZ is substantially lower, despite having much higher average column densities. CMZ clouds with high CDGFs are well-known sites of active star formation. The inability of most gas in the CMZ to form compact substructures is likely responsible for the dearth of star formation in the CMZ, surprising considering its high density. The factors responsible for the low CDGF are not yet understood but are plausibly due to the extreme environment of the CMZ, having far-reaching ramifications for our understanding of the star formation process across the cosmos.

description: Over the past 25 years, traditional agricultural co-operatives have been challenged by competition from local investor-owned firms and multinational companies, deregulation and globalization of trade, and increased market concentration in suppliers and purchasers. At the same time, co-operatives have constantly been seeking to add value to their member services through expansion and/or adoption of new technology. The capital investment needed for these endeavours has to be financed, and for traditional co-operatives the major source of financing new investments has been long-term borrowing. As a result some co-operatives are characterized by high debt loads, which may result in increased financial risk exposure. Important factors that may influence the level of financial risk exposure are the potential conflicts between managerial self-interest and the interest of the owners of the firm (Jensen, 1986; Jensen and Meckling, 1976) and the impact of these differences on the choice of capital structure (Friend and Lang, 1988; Firth, 1995; Matthews et al., 1994). Despite the considerable literature (e.g., Jensen and Meckling, 1976; Lewis and Sappington, 1995), the impact that differences in attitudes between managers and directors/members have upon the decision making process has remained a relatively unexplained aspect of agency problems, especially in member-owned firms. This article assesses the social-psychological and demographic variables that affect co-operative decision makers’ attitudes toward long-term debt financing and their intentions to increase long-term borrowing.

description: Accretion induced collapse (AIC) may be responsible for the formation of some interesting neutron star binaries, e.g., millisecond pulsars, intermediate-mass binary pulsars, etc. It has been suggested that oxygen-neon white dwarfs (ONe WDs) can increase their mass to the Chandrasekhar limit by multiple He-shell flashes, leading to AIC events. However, the properties of He-shell flashes on the surface of ONe WDs are still not well understood. In this article, we aim to study He-shell flashes on the surface of ONe WDs in a systematic approach. We investigated the long-term evolution of ONe WDs accreting He-rich material with various constant mass-accretion rates by time-dependent calculations with the stellar evolution code Modules for Experiments in Stellar Astrophysics (MESA), in which the initial ONe WD masses range from 1.1 to 1.35 M . We found that the mass-retention efficiency increases with the ONe WD mass and the mass-accretion rate, whereas both the nova cycle duration and the ignition mass decrease with the ONe WD mass and the mass-accretion rate. We also present the nuclear products in different accretion scenarios. The results presented in this article can be used in the future binary population synthesis studies of AIC events.

description: The United States provides a path to citizenship for its newcomers. Unlike other immigration countries, however, the United States does not have policies that ease assimilation or directly promote naturalization such as easily accessible and widely advertised language and civic instruction courses. Immigrants are by and large left on their own when facing legal and financial barriers or seeking instruction to pass the citizenship test. Not surprisingly, thus, we find that immigrants’ attributes such as educational attainment, English language proficiency, and income affect naturalization rates. This paper analyzes whether naturalization rates are also affected by neighborhood characteristics and informal networks for assistance and information. Towards that end, we estimate a binary model of immigrants’ citizenship status specifying the size of the immigrant enclave and its level of assimilation as key explanatory variables. The study uses 2005 ACS data, and focuses on immigrants from the Caribbean islands in the New York area. The results suggest that who they are and where they live has substantial impacts on immigrants’ propensities to have acquired US citizenship. Citizenship is unlikely for recent arrivals, those who do not speak English well, are poorly educated, and have a low income. Moreover, living in a neighborhood with a well assimilated immigrant enclave enhances the chance of acquiring US citizenship. This effect is stronger for highly educated than for poorly educated immigrants and thus misses the more vulnerable segments of the immigrant population.

description: We determine stability and attractor properties of random Boolean genetic network models with canalyzing rules for a variety of architectures. For all power law, exponential, and flat in-degree distributions, we find that the networks are dynamically stable. Furthermore, for architectures with few inputs per node, the dynamics of the networks is close to critical. In addition, the fraction of genes that are active decreases with the number of inputs per node. These results are based upon investigating ensembles of networks using analytical methods. Also, for different in-degree distributions, the numbers of fixed points and cycles are calculated, with results intuitively consistent with stability analysis; fewer inputs per node implies more cycles, and vice versa. There are hints that genetic networks acquire broader degree distributions with evolution, and hence our results indicate that for single cells, the dynamics should become more stable with evolution. However, such an effect is very likely compensated for by multicellular dynamics, because one expects less stability when interactions among cells are included. We verify this by simulations of a simple model for interactions among cells.

description: The need to decrease the United States’ dependency on oil has pushed ethanol to the forefront of energy sources. In the U.S., corn is used to make ethanol. Corn-based ethanol production has been profitable over the past few years, but there has been a near doubling of corn prices in late 2006 and early 2007 (Outlaw, et. al., 2007). The trend is a constant rise in prices, which has given way to ethanol production by other sources of raw materials like sugarcane. Sugarcane ethanol is the most cost-efficient biofuel available anywhere in the world, and in the United States, the government supports sugar prices. Through the US sugar policy, sugar prices are controlled, and foreign imports are severely limited. Brazil is leading the way in sugarcane ethanol, and its neighbors in Central America are following suit. In 2006, the Central American Free Trade Agreement (CAFTA) was established. The agreement allows sugar imports into the U.S. from these countries duty free. Those countries have extreme ethanol growth potential with low production costs and large sources of sugarcane. This paper uses GIS and statistical tools to determine the impact of the expanded U.S. sugar imports from CAFTA-DR countries on the U.S. ethanol market in terms of production and regional concentration. To estimate the relationship between ethanol production and sugar imports, an OLS regression model has been developed with monthly U.S. ethanol production as a function of imported sugarcane, gas, ethanol , and corn prices; covering January 2000 to September 2008.

description: Tight binding (TB) models are one approach to the quantum mechanical many particle problem. An important role in TB models is played by hopping and overlap matrix elements between the orbitals on two atoms, which of course depend on the relative positions of the atoms involved. This dependence can be expressed with the help of Slater-Koster parameters, which are usually taken from tables. Recently, a way to generate these tables automatically was published. If TB approaches are applied to simulations of the dynamics of a system, also derivatives of matrix elements can appear. In this work we give general expressions for first and second derivatives of such matrix elements. Implemented in a computer program they obviate the need to type all the required derivatives of all occuring matrix elements by hand.

The association between deceptive motivations and personality disorders in male offenders

description: The detection of deception is an integral part of any forensic assessment. Unfortunately, the motives underlying the use of deceptive strategies by offenders and how these may differ between different types of personality-disordered offenders are not well established. The aim of the present study was to identify different deception-related motivations in a sample of offenders and to examine the relationship between these motivations and personality pathology. Archived file and videotaped information for 103 Canadian federal offenders were reviewed in order to identify personality disorder pathology, as well as patterns of deceptive motivations (compulsive, secretive, avoiding punishment, avoiding negative evaluation, protective, to obtain a reward, to heighten self-presentation, altruistic, and careless). In general, as expected within a forensic context, offenders lied to avoid punishment. With respect to the other motivational categories investigated, personality pathology was found to significantly mediate the motivational patterns leading to offender-perpetrated deception. The relevance of these findings to credibility assessment and personality pathology is discussed.

description: Electron dynamics in metallic clusters are examined using a time-dependent density functional theory that includes a 'memory term', i.e. attempts to describe temporal non-local correlations. Using the Iwamoto, Gross and Kohn exchange-correlation (XC) kernel we construct a translationally invariant memory action from which an XC potential is derived that is translationally covariant and exerts zero net force on the electrons. An efficient and stable numerical method to solve the resulting Kohn-Sham equations is presented. Using this framework, we study memory effects on electron dynamics in spherical Jellium 'gold clusters'. We find memory significantly broadens the surface plasmon absorption line, yet considerably less than measured in real gold clusters, attributed to the inadequacy of the Jellium model. Two-dimensional pump-probe spectroscopy is used to study the temporal decay profile of the plasmon, finding a fast decay followed by slower tail. Finally, we examine memory effects on high harmonic generation, finding memory narrows emission lines.

description: The United States engagement in nonreciprocal preferential trade arrangements has been proliferating with several developing countries throughout the past couple of decades. One of the oldest and more successful of these arrangements has been the Caribbean Basin Initiative (CBI).The CBI is a general term used to refer to the Caribbean Basin Economic Recovery Act of 1983 (CBERA), the Caribbean Basin Economic Recovery Expansion Act of 1990 (CBERA Expansion Act), and the Caribbean Basin Trade Partnership of 2000 (CBTPA) (Ozden and Sharma 2006). The central premise behind the plan was that, by encouraging the CBI countries to become more open and liberal, trade would expand – and eventually translate into economic development and growth (Deere, 1990). The partnership between the U.S. and the CBI provides duty and quota free treatment for 1) textile and apparel products assembled from U.S. fabric in CBI beneficiary countries from U.S. fabric and 2) yarn and apparel assembled from CBI regional fabric, subject to a quantitative limit which increases over time. Cotton is a major commodity for the U.S. generating about $4-5 billion in annual cash receipts (Dodson 1995). Furthermore, cotton is a major raw material for the textile and apparel industries creating heavy dependence by these industries on cotton production. The demand for raw fiber is derived from consumer demand for textile products where cotton is an important textile fiber (Marseli and Epperson, 2002). This paper analyzes the effects these regional trade agreements have on CBI countries cotton imports from US by calculating the associated trade creation and trade diversion values.

description: Agriculture is a vulnerable sector of the U.S economy, accounting for 13% of Gross Domestic Product and 15% of employment. It produces quality cheap food for domestic consumption and accounts for more than $65 billion in export revenues. Contagious animal diseases like Foot and Mouth Disease (FMD) are often referred to as economic diseases because of the magnitude of harm they cause producers, local communities and the consequences in international trade. Losses from the 2001 FMD outbreak in the United Kingdom are estimated at $10.7 to $11.7 billion. The total cost of an FMD outbreak is the sum of eradication cost, production losses, and the loss of exports. This paper examines the export effects of a bioterrorist attack such as the introduction of FMD on the US beef industry. The context is to model the US beef market as a price taker on the international beef market, the simplifying “small open economy” assumption of international economics. Although, the beef market is linked to beef prices around the world, we tend to conceive of the US beef market in terms of domestic supply and demand and the resulting domestic equilibrium price. The excess supply of beef is the difference between quantities supplied and demanded that increases with price and responds to other influences on domestic supply and demand. We assumed that U.S consumers will exercise more caution when purchasing beef at grocery store as a result of the outbreak of FMD. As U.S consumers alter their diet, poultry and pork will become good substitutes with poultry having a higher demand than pork. The economic impact of FMD is simulated based on expected changes in price of beef and its substitutes based on three different scenarios of the levels of FMD occurrences.
Time-series and network analysis in quantum dynamics: Comparison with classical dynamics

description: Time-series analysis and network analysis are now used extensively in diverse areas of science. In this paper, we applythese techniques to quantum dynamics in an optomechanical system: specifically, the long-time dynamics of the mean photon number in an archetypal tripartite quantum system comprising a single-mode radiation field interacting with a two-level atom and an oscillating membrane. We also investigate a classical system of interacting Duffing oscillators which effectively mimics several of the features of tripartite quantum-optical systems. In both cases, we examine the manner in which the maximal Lyapunov exponent obtained from a detailed time-series analysis varies with changes in an appropriate tunable parameter of the system. Network analysis is employed in both the quantum and classical models to identify suitable network quantifiers which will reflect these variations with the system parameter. This is a novel approach towards (i) examining how a considerably smaller data set (the network) obtained from a long time series of dynamical variables captures important aspects of the underlying dynamics, and (ii) identifying the differences between classical and quantum dynamics.

description: We discuss the calculation of the strange magnetic radius of the proton in chiral perturbation theory. In particular we investigate the low energy component of the loop integrals involving kaons. We separate the chiral calculation into a low energy part and a high energy component through use of a momentum space separation scale. This separation shows that most of the chiral calculation comes from high energies where the effective field theory treatment is not valid. The resulting low energy prediction is in better agreement with dispersive treatments. Finally, we briefly discuss magnetic moments and show how our techniques can help resolve an old puzzle in understanding the magnetic moments of the proton and Sigma^+.

description: This case summarizes the available information on the 2007 Castleberry’s recall and food recalls in general, and raises questions prompted by a recall of this magnitude. A massive, nationwide recall of Castleberry’s canned food due to botulism in the summer of 2007 illustrates the complexity of the food industry. Product from a single production line at a single plant, packed under 90 labels (the company’s own store brands and foodservice), spurred a recall of tens of millions of cans of food. While every recall is important and unique, the breadth of the Castleberry’s Food Company recall and the severe consequences from botulism lend themselves to this exemplary case study.

description: It has been proposed recently that, within the framework of split Supersymmetry, long lived gluinos generated in astrophysical sources could be detected using the signatures of the air showers they produce, thus providing a lower bound for their lifetime and for the scale of SUSY breaking. We present the longitudinal profile and lateral spread of $G$-hadron induced extensive air showers and consider the possibility of measuring them with a detector with the characteristics of the Pierre Auger Observatory.

Unusual role of ligand states in the electronic properties of a parent Fe-based superconductor, CaFe2As2

description: We investigate the role of ligand states in the electronic properties of CaFe2As2 using high-resolution hard x-ray photoemission spectroscopy (HAXPES) at different sample temperatures. Experimental results indicate that the binding energy of Ca is close to that for 2+ charge state of Ca atoms and the other constituent elements, Fe and As possess electronic configuration close to that in elemental systems. No difference is observed in the As 3p core level spectra with the change of emission angle and/or the change in sample temperature. This is surprising as the Ca atoms at the cleaved sample surface reorganizes itself to form linear structures which is expected to influence Ca-As hybridization leading to significant difference in surface and bulk electronic structures. Moreover, CaFe2As2 undergoes structural and magnetic phase transition at 170 K, and strong Fe-As hybridization provides pathways for electron dynamics. Clearly, further studies are required to resolve these puzzling observations.
