description: We have studied the in- and out-of-plane magnetic penetration depths in the hole- doped iron based superconductor Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_{2}$ ($T_{c}\approx$ 30K). The study was performed on single crystals grown from different fluxes and we find that the results are nearly the same. The in-plane London penetration depth $λ_{ab}$ does not show exponential saturation at low temperature, as would be expected from a fully gapped superconductor. Instead, $λ_{ab}(T)$ shows a power-law behavior, $λ\propto T^{n}$ ($n\approx 2$), down to $T\approx 0.02 T_{c}$, similar to the electron doped Ba(Fe$_{1-x}$Co$_{x}$)$_{2}$As$_{2}$. The penetration depth anisotropy $γ_λ=λ_{c}(T)/λ_{ab}(T)$ increases upon cooling, opposite to the trend observed in the anisotropy of the upper critical field, $γ_ξ=H_{c2}^{\perp c}(0)/H_{c2}^{\parallel c}(0)$. These are universal characteristics of both the electron and hole doped 122 systems, suggesting unconventional superconductivity. The behavior of the in-plane superfluid density $ρ_{ab}(T)$ is discussed in light of existing theoretical models proposed for the iron pnictides superconductors.

description: Orthorhombically distorted perovskite manganites, RMnO3 with R being a trivalent rare-earth ion, exhibit a variety of magnetic and electric phases including multiferroic (i.e. concurrently magnetic and ferroelectric) phases and fascinating magnetoelectric phenomena. We theoretically study the phase diagram of RMnO3 by constructing a microscopic spin model, which includes not only the superexchange interaction but also the single-ion anisotropy (SIA) and the Dzyaloshinsky-Moriya interaction (DMI). Analysis of this model using the Monte-Carlo method reproduces the experimental phase diagrams as functions of the R-ion radius, which contain two different multiferroic states, i.e. the ab-plane spin cycloid with ferroelectric polarization P//a and the bc-plane spin cycloid with P//c. The orthorhombic lattice distortion or the second-neighbor spin exchanges enhanced by this distortion exquisitely controls the keen competition between these two phases through tuning the SIA and DMI energies. This leads to a lattice-distortion-induced reorientation of P from a to c in agreement with the experiments. We also discuss spin structures in the A-type antiferromagnetic state, those in the cycloidal spin states, origin and nature of the sinusoidal collinear spin state, and many other issues.

The hemicelluloses of Douglas fir
Creators: name: Abdurahman, Nizam
Publisher: name: University of British Columbia

description: The Douglas fir holocellulose was prepared by Wise’s(8) modification of Jayme's sodium chlorite procedure(9). The hemicelluloses were extracted using 24% potassium hydroxide followed by 17% sodium hydroxide containing 5% boric acid. Meier(31) reported that barium hydroxide can be used to purify polysaccharide mixtures. The mode of action presumably being the formation of an insoluble complex with the cis-hydroxyl groups of the mannose or galactose integers. By using this method of purification Timell(30) isolated a galactoglucomannan from a 24% potassium hydroxide extract of eastern hemlock holocellulose. Following Timell's scheme the attempt to isolate a galactoglucomannan from Douglas fir did not proceed with the facility suggested. Two purifications by Meier's procedure failed to remove the xylose containing polysaccharide. Further batches of freshly prepared holocellulose were extracted and repeated attempts at the isolation and purification of a galactoglucomannan are at present being pursued. The addition of barium hydroxide not only removed the galactoglucomannan fraction but also purified the xylan which remained in solution. Four barium hydroxide treatments followed by two purifications by means of Fehling's solution gave an arabino-4-0-methyl-D-glucuronoxylan freed from galactose. Previous attempts at the purification of this type of polysaccharide from softwoods have failed to remove the galactose residues. A glucomannan fraction was extracted using 17.5% sodium hydroxide containing 5% boric acid. Four fractionations by the barium hydroxide procedure failed to remove the xylose residues. Two further fractionations via the copper complex removed the last traces of xylose but the fraction still contained about 8% galactose. This is not unusual for it has been reported that the majority of gymnosperm glucomannans contain at least 4% galactose. The glucose to mannose ratio is approximately 1:3.5 which is in the order of a true glucomannan. It appears that the possibility should be seriously considered that the galactose residues present in the so called "glucomannans" are actually integral parts of these polysaccharides. Additional experimental data in the near future will undoubtedly serve to solve the problem.

description: We continue the previous study on the existence of different intermediate Hamiltonians in type A N-fold supersymmetric systems and carry out an exhaustive investigation on the N=3 case. In contrast with the N=2 case, we find various patterns in the existence of intermediate Hamiltonians due to the presence of two different intermediate positions in a factorized type A 3-fold supercharge. In addition, all the N=3 models are strictly restricted to at most elliptic type, which enables us to make the complete classification of the systems which admit intermediate Hamiltonians. Finally, we show realizations of third-order parasupersymmetry and variant generalized 3-fold superalgebras by such systems.

Episodic X-ray Emission Accompanying the Activation of an Eruptive Prominence: Evidence of Episodic Magnetic Reconnection

description: We present an X-ray imaging and spectroscopic study of a partially occulted C7.7 flare on 2003 April 24 observed by RHESSI that accompanied a prominence eruption observed by TRACE. (1) The activation and rise of the prominence occurs during the preheating phase of the flare. The initial X-ray emission appears as a single coronal source at one leg of the prominence and it then splits into a double source. Such a source splitting happens three times, each coinciding with an increased X-ray flux and plasma temperature, suggestive of fast reconnection in a localized current sheet and an enhanced energy release rate. In the late stage of this phase, the prominence displays a helical structure. These observations are consistent with the tether-cutting and/or kink instability model for triggering solar eruptions. (2) The eruption of the prominence takes place during the flare impulsive phase. Since then, there appear signatures predicted by the classical CSHKP model of two-ribbon flares occurring in a vertical current sheet trailing an eruption. These signatures include an EUV cusp and current-sheet-like feature (or ridge) above it. There is also X-ray emission along the EUV ridge both below and above the cusp, which in both regions appears closer to the cusp at higher energies in the thermal regime. This trend is reversed in the nonthermal regime. (3) Spectral analysis indicates thermal X-rays from all sources throughout the flare, while during the impulsive phase there is additional nonthermal emission which primarily comes from the coronal source below the cusp. This source also has a lower temperature, a higher emission measure, and a much harder nonthermal spectrum than the upper sources.

description: Manganese phosphide MnP has been investigated for decades because of its rich magnetic phase diagram. It is well known that the MnP exhibits the ferromagnetic phase transition at $\Tc=292$ K and the helical magnetic phase below $\TN=47$ K at zero field. Recently, a novel magnetic phase transition was observed at $T^* = 282$ K when the magnetic field is lower than 5 Oe. However, the nature of the new phase has not been illuminated yet. In order to reveal it, we performed the AC and the DC magnetization measurements for a single crystal MnP at very low field. A divergent behavior of the real and the imaginary part of the AC susceptibility and a sharp increase of the DC magnetization was observed at $T^*$, indicating the magnetic phase transition at $T^*$. Furthermore a peculiar temperature hysteresis was observed: namely, the magnetization depends on whether cooling sample to the temperature lower than $\TN$ or not before the measurements. This hysteresis phenomenon suggests the complicated nature of the new phase and a strong relation between the magnetic state of the new phase and the helical structure.

The Construction of "Cold War Reality" through Intercountry Adoption Law: A top-down and bottom-up Analysis

Subjects: subject: Intercountry adoption

subject: Family

description: U.S. intercountry adoption law was a fairly recent development, and matters related to foreign orphans were only partially covered under temporary, emergency immigration laws regarding refugees, such as the Displaced Persons Act of 1948 (DPA) and the Refugee Relief Act of 1953 (RRA). This paper presents a two-fold argument. Firstly, this series of special legislation regarding foreign orphans originated—not in World War I nor as a consequence of World War II—but in tandem with the Cold War along with other economic and military measures. Secondly, this Cold War policy was not imposed on the U.S. citizenry. It was a result of their own initiatives. Specifically looking at individuals who helped pave the legal framework and build adoption programs from West Germany, Japan, and South Korea in the 1950s, their efforts redefined families into humanitarian units and acknowledged the basic rights of children to a family. This in turn helped construct a certain “Cold War reality,” as they justified U.S. foreign intervention.
Higher Spins and Current Exchanges

Publisher: name: INFN Open Access Repository

description: The simplest higher-spin interactions involve classical external currents and
symmetric tensors $\phi_{\m_1 ... \m_s}$, and convey three instructive lessons.
The first is a general form of the van Dam-Veltman-Zakharov discontinuity in
flat space for this class of fields. The second is the rationale for its
disappearance in (A)dS spaces. Finally, the third is a glimpse into an option
which is commonly overlooked in Field Theory, and which both higher spins and
String Theory are confronting us with: one can well allow in the Lagrangians
non-local terms that do not spoil the local nature of physical quantities.
The structure of the nucleon from generalized parton distributions

Publisher: name: PoS LC2008:014,2008
Year: 2008

description: Generalized parton distributions (GPDs) have become a standard QCD tool for
analyzing and parametrizing the non perturbative parton structure of hadron
targets. GPDs might be viewed as non-diagonal overlaps of light-cone wave
functions and offer the opportunity to study the partonic content of the
nucleon from a new perspective, allowing one to study the interplay between
longitudinal and transverse partonic degrees of freedom. In particular, we will
review some of the new information encoded in the GPDs through the definition
of impact-parameter dependent parton distributions and form factors of the
energy-momentum tensor, by exploiting different dynamical models for the
nucleon state.

Radio signals of particle dark matter
Creators: name: Regis, Marco
Publisher: name: INFN Open Access Repository
Year: 2011

description: In most of particle dark matter (DM) models, the DM candidate injects sizable
fluxes of high-energy electrons and positrons through its annihilations or
decays. Emitted in regions with magnetic field, they in turn give raise to a
synchrotron radiation, which typically covers radio and infrared bands. We
discuss the possibility of detecting signatures of Galactic and extra-galactic
DM in the total intensity and small-scale anisotropies of the radio background.
Notes on Strings and Higher Spins
Creators: name: A. Sagnotti
Publisher: name: INFN Open Access Repository
Year: 2012

description: These notes are devoted to the intriguing and still largely unexplored links
between String Theory and Higher Spins, the types of excitations that lie
behind its most cherished properties. A closer look at higher-spin fields
provides some further clues that String Theory describes a broken phase of a
Higher-Spin Gauge Theory. Conversely, string amplitudes contain a wealth of
information on higher-spin interactions that can clarify long-standing issues
related to their infrared behavior.

Intrinsic Half-Metallicity in Modified Graphene Nanoribbons

Publisher: name: arXiv
Year: 2009
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

subject: FOS: Physical sciences

description: We perform first-principles calculations based on density functional theory to study quasi one-dimensional edge-passivated (with hydrogen) zigzag graphene nanoribbons (ZGNRs) of various widths with chemical dopants, boron and nitrogen, keeping the whole system isoelectronic. Gradual increase in doping concentration takes the system finally to zigzag boron nitride nanoribbons (ZBNNRs). Our study reveals that, for all doping concentrations the systems stabilize in anti-ferromagnetic ground states. Doping concentrations and dopant positions regulate the electronic structure of the nanoribbons, exhibiting both semiconducting and half-metallic behaviors as a response to the external electric field. Interestingly, our results show that ZBNNRs with terminating polyacene unit exhibit half-metallicity irrespective of the ribbon width as well as applied electric field, opening a huge possibility in spintronics device applications.

Collective flavour transitions of supernova neutrinos
Creators: name: Tamborra, Irene
Publisher: name: INFN Open Access Repository
Year: 2009

description: When the neutrino density is very high, as in core-collapse supernovae,
neutrino-neutrino interactions are not negligible and can appreciably affect
the evolution of flavour. The physics of these phenomena is briefly
highlighted, and their effects are shown on observable energy spectra from a
future galactic supernova within two-neutrino and three-neutrino frameworks.
Detection of such effects could provide a handle on two unknowns: the neutrino
mass hierarchy, and the mixing angle theta(13).
NNLO QCD correction to vector boson production at hadron colliders
Creators: name: Ferrera, Giancarlo
Publisher: name: INFN Open Access Repository
Year: 2010

description: We present a fully-exclusive next-to-next-to-leading order (NNLO) QCD
calculation for vector boson production in hadron-hadron collisions. The
calculation is implemented in a parton level Monte Carlo program, which
includes the gamma-Z interference, finite-width effects, the leptonic decay of
the vector bosons and the corresponding spin correlations. The code allows the
user to apply arbitrary (though infrared safe) kinematical cuts on the
final-states and to compute distributions in the form of bin histograms. We
show some illustrative numerical results at the Tevatron and the LHC.

A Noncrossing Basis for Noncommutative Invariants of SL(2,C)
Creators: name: Lehner, Franz
Publisher: name: arXiv
Year: 2009
Subjects: subject: Combinatorics (math.CO)

subject: 16R30, 46L54

description: Noncommutative invariant theory is a generalization of the classical invariant theory of the action of $SL(2,\IC)$ on binary forms. The dimensions of the spaces of invariant noncommutative polynomials coincide with the numbers of certain noncrossing partitions. We give an elementary combinatorial explanation of this fact by constructing a noncrossing basis of the homogeneous components. Using the theory free stochastic measures this provides a combinatorial proof of the Molien-Weyl formula in this setting.

description: In this paper, we describe an experiment performed at the Laboratoire de Physique des Lasers and dedicated to an optical measurement of the Boltzmann constant. With the proposed innovative technique, determining comes down to an ordinary frequency measurement. The method consists in measuring as accurately as possible the Doppler absorption profile of a rovibrational line of ammonia in thermal equilibrium. This profile is related to the Maxwell-Boltzmann molecular velocity distribution along the laser beam. A fit of the absorption line shape leads to a determination of the Doppler width proportional to sqrt(kT) and thus to a determination of the Boltzmann constant. The laser source is an ultra-stable CO2 laser with a wavelength . The absorption cell is placed in a thermostat keeping the temperature at 273.15 K within 1.4 mK. We were able to measure with a relative uncertainty as small as 3.8x10-5, which represents an improvement of an order of magnitude for an integration time comparable to our previous measurement published in 2007 [1]

An external-shock origin of the E_p-E_gamma relation for Gamma-Ray Bursts

description: We investigate the possibility that the E_p propto E_gamma^{1/2} relation between the peak energy E_p of the nuF_nu spectrum and energy output E_gamma for long-duration GRBs arises from the external shock produced by the interaction of a relativistic outflow with the ambient medium. To that aim, we take into account the dependence of all parameters which determine E_p and E_gamma on the radial distribution of the ambient medium density and find that the E_p-E_gamma relation can be explained if the medium around GRBs has a universal radial stratification. For various combinations of GRB radiative process (synchrotron or inverse-Compton) and dissipation mechanism (reverse or forward shock), we find that the circumburst medium must have a particle density with a radial distribution different than the R^{-2} expected for constant mass-loss rate and terminal speed.

Uno studio condotto da ricercatori dell’Università del Texas ha mostrato che i rilievi presenti all’interno dei crateri di Marte possono aiutarci a ricostruire il suo passato. Lo studio ha permesso di risalire fino al Noachiano, ovvero il periodo in cui Marte è passato da un ambiente umido a uno secco
