description: The precise momentum dependence of the superconducting gap in the iron-arsenide superconductor with Tc = 32K (BKFA) was determined from angle-resolved photoemission spectroscopy (ARPES) via fitting the distribution of the quasiparticle density to a model. The model incorporates finite lifetime and experimental resolution effects, as well as accounts for peculiarities of BKFA electronic structure. We have found that the value of the superconducting gap is practically the same for the inner Gamma-barrel, X-pocket, and "blade"-pocket, and equals 9 meV, while the gap on the outer Gamma-barrel is estimated to be less than 4 meV, resulting in 2Delta/kT_c=6.8 for the large gap, and 2Delta/kT_c<3 for the small gap. A large (77 \pm 3%) non-superconducting component in the photoemission signal is observed below T_c. Details of gap extraction from ARPES data are discussed in Appendix.

description: Recent lattice data have reported an infrared suppressed, positivity violating gluon propagator which is nonvanishing at zero momentum and a ghost propagator which is no longer enhanced. This paper discusses how to obtain analytical results which are in qualitative agreement with these lattice data within the Gribov-Zwanziger framework. This framework allows one to take into account effects related to the existence of gauge copies, by restricting the domain of integration in the path integral to the Gribov region. We elaborate to great extent on a previous short paper by presenting additional results, also confirmed by the numerical simulations. A detailed discussion on the soft breaking of the BRST symmetry arising in the Gribov-Zwanziger approach is provided.

Diagnoses. This species can be easily distinguished from other related species by the elongate body. Etymology. The Latin adjective “ longum ” refers to the elongate body and male legs of the new species. Biological notes. All specimens were collected from a log covered with white fungus (Fig. 43). Territorial behavior of the male was observed by the collector, and it was described as follows: Each male occupies a small area on the fungi. Normally they highly raise bodies upon their long legs and they can shake their bodies up and down rapidly. Once, a small male was too close to a large one, the large male rushed to it immediately and the small male retreated quickly, without having body contact.

One-loop corrections to the string tension of the vortex in the Abelian Higgs model

description: We present an exact numerical computation of the one-loop correction of the string tension for the Nielsen-Olesen vortex in the Abelian Higgs model. The computations proceeds via the computation of the Euclidean Green's function for the gauge, Higgs and Faddeev-Popov fields using mode functions, and taking the appropriate trace. Renormalization is an essential part of this computation, it is done by removing leading order contributions from the numerical results so as to make these finite, and to add the divergent parts back, after suitable regularization and renormalization. We encounter and solve some problems which are specific to gauge theories and topological solutions. The corrections to the energy are found to be sizeable, but still smaller than the classical energy as long as g**2 is smaller than unity.

Cartan Invariants of Symmetric Groups and Iwahori-Hecke Algebras

description: Külshammer, Olsson and Robinson conjectured that a certain set of numbers determined the invariant factors of the $\ell$-Cartan matrix for $S_n$ (equivalently, the invariant factors of the Cartan matrix for the Iwahori-Hecke algebra $\mathcal{H}_n(q)$, where $q$ is a primitive $\ell$th root of unity). We call these invariant factors Cartan invariants. In a previous paper, the second author calculated these Cartan invariants when $\ell=p^r$, $p$ prime, and $r\leq p$ and went on to conjecture that the formulae should hold for all $r$. Another result was obtained, which is surprising and counterintuitive from a block theoretic point of view. Namely, given the prime decomposition $\ell=p_1^{r_1}... p_k^{r_k}$, the Cartan matrix of an $\ell$-block of $S_n$ is a product of Cartan matrices associated to $p_i^{r_i}$-blocks of $S_n$. In particular, the invariant factors of the Cartan matrix associated to an $\ell$-block of $S_n$ can be recovered from the Cartan matrices associated to the $p_i^{r_i}$-blocks. In this paper, we formulate an explicit combinatorial determination of the Cartan invariants of $S_n$--not only for the full Cartan matrix, \emph{but for an individual block}. We collect evidence for this conjecture, by showing that the formulae predict the correct determinant of the $\ell$-Cartan matrix. We then go on to show that Hill's conjecture implies the conjecture of KOR.

description: In this work we investigate the contribution to B(d,s) mixing from both scalar and vector unparticles in a number of scenarios. The emphasis of this work is to show the impact of the recently discovered 3 sigma evidence for new physics found in the CP phase of B(s) mixing. Here we show that the inclusion of the CP phase constraints for both B(d) and B(s) mixing improves the bounds set on the unparticle couplings by a factor of 2~4, and one particular scenario of scalar unparticles is found to be excluded by the 3 sigma measurement of phi(s).

description: We show that the open cluster Trumpler 20, contrary to the earlier findings, is actually an old Galactic open cluster. New CCD photometry and high-resolution spectroscopy are used to derive the main parameters of this cluster. At [Fe/H]=-0.11 for a single red giant star, the metallicity is slightly subsolar. The best fit to the color-magnitude diagrams is achieved using a 1.3 Gyr isochrone with convective overshoot. The cluster appears to have a significant reddening at E(B-V)=0.46 (for B0 spectral type), although for red giants this high reddening yields the color temperature exceeding the spectroscopic T_eff by about 200 K. Trumpler 20 is a very rich open cluster, containing at least 700 members brighter than M_V=+4. It may extend over the field-of-view available in our study at 20'x20'.

Crucial elements for the adaption of the positron beam are presented, which include the magnetic field termination, the optional transmission-type remoderator for brightness enhancement and the electrostatic system for acceleration and beam optics. The positron trajectories of the remoderated and the twofold remoderated beam have been simulated to optimize the system, i.e. to obtain a coherent beam of small diameter. Within a first beamtime we tuned the system and characterized the direct beam. For the twofold remoderated beam of 10keV energy, we experimentally observe a beam diameter of d < 1.3mm, which agrees well with the simulation.

With selected UHECR events, two-sided bounds on the eight nonisotropic parameters are obtained at the 10^{-18} level, together with an improved one-sided bound on the single isotropic parameter at the 10^{-19} level.

description: Long-range interactions play a central role in electron transport. At the same time, they present a challenge for direct computer simulations, since sufficiently large portions of the bath have to be included in the computation to accurately compute the Coulomb potential. This article presents a reduced-order approach, by deriving an open quantum model for the reduced density-matrix. To treat the transient dynamics, the problem is placed in a reduced-order framework. The dynamics, described by the Liouville von Neumann equation, is projected to subspaces using a Petrov-Galerkin projection. In order to recover the global electron density profile as a vehicle to compute the Coulomb potential, we propose a domain decomposition approach, where the computational domain also includes segments of the bath that are selected using logarithmic grids. This approach leads to a multi-component self-energy that enters the effective Hamiltonian. We demonstrate the accuracy of the reduced model using a molecular junction built from a Lithium chains.

description: We present a ground state cooling scheme for a nanomechanical resonator linearly coupled with a LC oscillator. The linear coupling, when periodically modulated at red detuning, up-converts the low-frequency nanomechanical mode to the high-frequency LC oscillator mode and generates backaction force that can cool the resonator to its ground state in the resolved-sideband regime. We also study the effect of the quantum backaction noise on the cooling due to the counter rotating term in the linear coupling. The scheme can be compared with laser cooling for the atomic systems and can be realized in superconducting circuits.

description: Through condensation of 4-n-alkoxybenzaldehyde (n = 2 to 8, 10, 12, 14, 16, 18) with (E)-1-(4-aminophenyl)-3-(thiophen-2-yl)prop-2-en-1-one, new homologous series of rod shaped calamite liquid crystals that merge Schiff base, chalcone and thiophene units have been prepared. All synthesized compounds were characterized by FT-IR, 1H-NMR and 13C-NMR spectroscopy. The liquid crystalline properties of the synthesized compounds were investigated using a polarizing optical microscope (POM) and differential scanning calorimetry (DSC). The results indicate that n-heptyloxy (A7) to n-tetradecyloxy (A14) derivatives exhibited monotropic nematic phase while the remaining derivatives of homologous series are non mesomorphic. The n-ethoxy derivative (A2) crystallizes under monoclinic, space group P21/c with unit cell dimension a = 19.343(4) Å, b = 5.8353(9) Å, c = 16.574(4) Å, β = 98.78(2) °, V = 1848.8(7) Å3. The dihedral angle between two phenyl rings of imine linkage in compound A2 is 51.64 (2) °.
Self-identification of the lyrical subject in Russian poetry (a draft typology)
Creators: name: Faustov, Andrey Anatolievich
Publisher: name: Università degli Studi di Milano
Year: 2014
Subjects: lyrical subject, lyrical I, lyrical character (lyrical hero), role character (role hero), self-identification, referring, attributing, Russian poetry, metaphor, metonymy

description: The end goal of this paper is to shed light on the changes in the lyrical subject self-identification logics that were characteristic of Russian poetry of the ‘modernist’ era. We are going to focus our attention exclusively on the poems with a lexically expressed I, which build the nucleus of the poetic fraction of literary texts and allow to get a clear idea about the mechanism of self-naming that we regard as fundamental for self-identification of the lyrical I.

The paper discriminates between the two methods of lyrical subject identification/self-identification: referring and attributing. Based on this, we suggest determining four basic functional incarnations of the lyrical subject in Russian poetry of the 18th–19th centuries, which are in part terminological reconsiderations of the conventional Russian philology categories. These incarnations are: 1) ‘anonymous’ lyrical I referring directly to the real author; 2) lyrical I referring to the author through the prism of in-text heteronymic or metonymic transcoding; 2) lyrical character (lyrical hero) referring to the author through the prism of metaphoric transcoding; 3) role character (role hero) with zero reference to the author.
The revolution that affected the strategies of lyrical self-identification in Russian poetry of the Silver Age manifested itself in some fundamental shifts. First of all, kaleidoscopic multiplication of lyrical I’s, both through the lyrics of specific poets and even within individual poems. Second, blurred boundaries between different incarnations of the lyrical subject that had been more or less clearly contrasted in poetry of the 19th century. Third, theatralization and problematization (to the extent of open conflicts) of the relationship between the author and his/her lyrical ‘doubles’.

description: With 40 or more transiting exoplanets now known, the time is ripe to seek patterns and correlations among their observed properties, which may give important insights into planet formation, structure, and evolution. This task is made difficult by the widely different methodologies that have been applied to measure their properties in individual cases. Furthermore, in many systems our knowledge of the planet properties is limited by the knowledge of the properties of the parent stars. To address these difficulties we have undertaken the first comprehensive analysis of the data for 23 transiting planets using a uniform methodology. We revisit several of the recently proposed correlations, and find new ones involving the metallicity of the parent stars.

The effects of external ankle support on ankle joint talar tilt
Creators: name: Bodnar, David Michael
Publisher: name: University of British Columbia
Year: 2010

description: Injury prevention in athletics has been the focus of much attention in recent years. Due to the frequency of injuries arising about the ankle joint, primarily involving the lateral collateral ligament complex, many attempts have been made to reinforce the ankle joint through the use of adhesive tape and preventative strapping. The purpose of preventative ankle strapping, as used in athletics, is to reduce the frequency and severity of ankle injuries. Numerous methods of preventative strapping have been employed in athletic circles which attempt to restrict or limit the specific motion causing the injury. The effectiveness of such devices in limiting only the motion which causes the injury is difficult to determine. The externally applied cloth ankle wrap is one such device which is thought to increase ankle joint stability and thus limit, to "some degree, plantar flexion and inversion. It is the combination of these two movements which are associated with the disruption of the lateral collateral ligament, resulting in a lateral ankle sprain. The purpose of this investigation was to study the effects of inversion forces applied to the ankle joints of cadavers and the resulting influence on talar tilt. The subproblem of this investigation was to examine the affects that an external cloth ankle support has on cadaver talar tilt when inversion forces were applied. Seventeen unpreserved cadaver ankle joints were used as subjects for this study. The limbs for the study had no history of previous injury and had not been subjected to any structural damage prior to experimentation. The seventeen cadaver limbs were examined by x-ray analysis under two test conditions, those being supported and unsupported. Each ankle joint was subjected to four regulated loads under each condition. X-ray photographs were taken at the time each force was applied. The limb testing took place within 24 hours postmortem. Attempts were made to test each ankle joint to failure under maximum loading conditions. The following hypotheses were tested for significance at the .05 level. 1. An increasing inversion force applied to the ankle joint of a cadaver produced increasing talar tilt in a plantar flexed foot position. 2. The application of an external cloth ankle support decreases the amount of talar tilt produced by inversion force in the plantar flexed foot. Preliminary analysis of variance revealed that there was a nonsignificant difference regarding the order in which the ankle joints were tested. Multivariate analysis of the data collected revealed that hypothesis #1 was supported at the 0.001 level and that hypothesis #2 was supported at the 0.002 level. No statistically supported conclusions could be drawn from the data collected from the maximum load conditions.
Academic Biography in the Context of the Anti-Formalist Campaign of the 1930s
Creators: name: Penskaya, Yelena N.
Publisher: name: Università degli Studi di Milano
Year: 2014
Subjects: formalism; anti-formalism campaign; destruction; academic institutions; biography

description: The paper is focused around two biographical themes. Theme one is history of demolishing Leningrad school of dramatic theory developed in the State Institute of History of Art (GIII) in the 1920s. In 1931, the GIII was closed by a Sovnarkom resolution and transformed into Len- ingrad division of the State Academy of Art Studies (LOGAIS) established by the same resolu- tion. Theme two is description of the ‘academic traumatism’, traumatic behavior and its bio- graphical effects caused by destruction of a whole scientific trend during the anti-formalism campaign of the early 1930s. Based on archival documents (from the Russian State Archive of Literature and Art), shorthand notes and reports on discussions of the 1930s, we analyze behav- ioral tactics of initiators, participants and victims of the longstanding stigmatization and catalog absolutory, denunciative and repentant narratives. In particular, this paper analyzes the un- published letter to the editors of Rabochiy i Teatr journal written by Alexander Slonimsky, one of the key players in development and obliteration of dramatic theory associated primarily with Alexei Gvozdev’s group and with transformation and dissolution of the leading humanities in- stitutes. The text of the letter appears to be engrained in the complicated mosaic of measures aimed to discredit Meyerhold’s theater practice and Gvozdev as the leader of the scientific school. Deliberate misinterpretation and corruption of self-descriptions along with reconstruc- tion of biographies are some of the most crucial factors that affected reception of cultural pro- jects and their creators in the 1930s and later.

A metodologia envolveu a análise visual assistida por IA, comparação com imagens de satélite referenciadas por Plus Code e a subsequente geração de metadados para enriquecer a prova digital. Discutem-se as implicações críticas da perda de metadados para a cadeia de custódia digital (conforme Lei nº 13.964/2019 e jurisprudência do STJ), os desafios da LGPD, a importância da geolocalização para a especificidade de atos processuais (Art. 243, CPP) e soluções de mitigação como ProofMode. O caso ilustra a necessidade de letramento digital crítico e a sinergia entre intuição humana e análise algorítmica em sistemas híbridos, conectando-se a pesquisas anteriores sobre limites da formalização e mente estendida no Direito.

We find three different types of solutions consistent with the dynamic domain walls. For every case, the solutions have singularity. Further more, in these backgrounds, we study the dynamics of domain walls. We qualitatively plot various form of the bulk metrics and the potential encountered by the domain walls. In many cases, depending upon the value of the parameters, the domain walls show bouncing universe and also undergo inflationary phase followed by standard decelerated expansion.

The relationship of individual anaerobic thresholds to total, alactic, and lactic oxygen debts after a set treadmill run
Creators: name: Wiley, James Preston
Publisher: name: University of British Columbia
Year: 2010

description: Anaerobic threshold speed (VTAM) was determined for 20 male university students using a continuous treadmill protocol. The onset of anaerobiosis was determined by analyzing excess CO₂ elimination. The following week, all subjects ran at the VTAM median speed of 7.25 miles per hour for 10 minutes. Recovery oxygen consumption was monitored after this run. Application of double exponential equations by computer and subsequent integration, calculated Total, Alactic, and Lactic Oxygen Debts. Subjects who ran above their VTAM (group L-VTAM) had significantly (p < .05) higher total, lactic and alactic debts than those subjects who ran below their VTAM (group H-VTAM). The total debt showed a significant (p < .05) negative correlation (r=-.77) to in; group L-VTAM. This appears to be due to the increasing lactic debt, that was also significantly (p < .05) negatively correlated (r=-.73) to VTAM. Group H-VTAM did not exhibit this characteristic. This study demonstrates that VTAM is a critical factor in determining oxygen debt and therefore, work above this point results in the onset of metabolic acidosis, which may limit the optimal running speed for a given distance.
Effective Theory of Braid Excitations of Quantum Geometry in terms of Feynman Diagrams

description: We study interactions amongst topologically conserved excitations of quantum theories of gravity, in particular the braid excitations of four-valent spin networks. These have been shown previously to propagate and interact under evolution rules of spin foam models. We show that the dynamics of these braid excitations can be described by an effective theory based on Feynman diagrams. In this language, braids which are actively interacting are analogous to bosons, in that the topological conservation laws permit them to be singly created and destroyed. Exchanges of these excitations give rise to interactions between braids which are charged under the topological conservation rules.

Magnetic-field induced quantum-size cascades in superconducting nanowires

description: In high-quality nanowires, quantum confinement of the transverse electron motion splits the band of single-electron states in a series of subbands. This changes in a qualitative way the scenario of the magnetic-field induced superconductor-to-normal transition. We numerically solve the Bogoliubov-de Gennes equations for a clean metallic cylindrical nanowire at zero temperature in a parallel magnetic field and find that for diameters D < 10-15 nm, this transition occurs as a cascade of subsequent jumps in the order parameter (this is opposed to the smooth second-order phase transition in the mesoscopic regime). Each jump is associated with the depairing of electrons in one of the single-electron subbands. As a set of subbands contribute to the order parameter, the depairing process occurs as a cascade of jumps. We find pronounced quantum-size oscillations of the critical magnetic field with giant resonant enhancements. In addition to these orbital effects, the paramagnetic breakdown of Cooper pairing also contributes but only for smaller diameters, i. e., D < 5 nm.
“The infernal underside of the restaurant industry“
Creators: name: Bruegel, Martin
Publisher: name: Austrian Journal of Historical Studies

description: At the height of France’s gastronomic reputation in the 1920s, the union of Paris cooks – La Chambre syndicale ouvrière des cuisiniers de Paris et régions saisonnières – engaged in a protracted struggle to improve workplace hygiene. Theirs is an apt case to move grassroot campaigns for public health to a central place in general and working-class historiography. First, the cooks’ union articulated the importance of sanitary-related issues by using a wide repertoire of actions (fliers, newspaper articles, lobby- ing, meetings). Second, rather than focusing on particular ailments for which victims and their advocates sought retroactive compensation, the cooks brandished an ecological understanding of the risks that lurked in restaurant kitchens. In effect, their goal was the prevention of occupational hazards. Third, faced with governmental inertia and contrary to assertions in historical writing based exclusively on official reporting, the cooks launched a strike to promote the sanitary reform of restaurant kitchens. The historical study of cooks’ activism is beneficial for a number of reasons. It showcases the cooks’ media savvy in terms of how they brought into play issues of consumer pro- tection and gastronomic reputation. After all, spoiled restaurant meals en- dangered the clienteles’ health, tainted the country’s culinary prominence, and hurt tourism. The link between production and consumption proved to be a mechanism with which to obtain access to the government. The pressure exerted by the cooks’ union ultimately prompted an official investigation into restaurant hygiene, the results of which led to an unprecedented, precocious attempt at democratic industrial relations. Cooks, chefs, employers, and civil servants sat down to find technical solutions for hygienic deficiencies in restaurant kitchens. The experience was short-lived, but when the left conquered the Paris city hall in 1936, a new ordinance on sanitary regulations afforded restaurant hygiene a special section.

A variation of the clock paradox and a distinguishing feature of an inertial frame

description: The clock paradox is analyzed for the case when the onward and return trips cover the same <> (as observed by the traveling twin) but at unequal velocities. In this case the stationary twin observes the distances covered by her sister during the onward and return trips to be different. The analysis is presented using formulations of special relativity and the only requirement for consistency is that all observations are made from any one chosen inertial frame. The analysis suggests that a defining feature of an inertial frame should be based on the continued maintenance of the distinctive synchronicity of the clocks co-moving with it.

description: The results of the magnetization studies on Pr_{5}Ge_{3}and Tb_{5}Ge_{3} single crystals are reported. Single Crystals of Pr_{5}Ge_{3} and Tb_{5}Ge_{3} compounds were successfully grown by Czochralski method. These compounds crystallize in a Mn_{5}Si_{3} type hexagonal structure with space group P6_{3}/mcm. Ferromagnetic correlations set in at around 36 K in Pr_{5}Ge_{3} in the ab plane followed by an antiferromagnetic transition at 13 K. Along the c-axis the magnetization shows a ferromagnetic transition around 13 K with an overall ferrimagnetic behavior. At 2K, the magnetic isotherm of the compound along [0001] direction is typical for a ferromagnet, while a field induced ferromagnetic type response is observed along the [10\overline{\mathit{1}}0] direction. Hexagonal ab plane or [10\overline{\mathit{1}}0] direction was found to be the easy axis of magnetization. Tb_{5}Ge_{3} orders antiferromagneticaly at 85 K with the hexagonal ab plane as easy axis of magnetization. The compound shows a field induced ferromagnetic behavior in its magnetic isotherm at 2 K.

Non-Meissner electrodynamics and knotted solitons in two-component superconductors

description: I consider electrodynamics and the problem of knotted solitons in two-component superconductors. Possible existence of knotted solitons in multicomponent superconductors was predicted several years ago. However their basic properties and stability in these systems remains an outstandingly difficult question both for analytical and numerical treatment. Here I propose a new perturbative approach to treat self-consistently all the degrees of freedom in the problem. I show that there exists a length scale for a Hopfion texture where the electrodynamics of a two-component superconductor is dominated by a self-induced Faddeev term, which is a stark contrast to the Meissner electrodynamics of single-component systems. I also show that at certain short length scales knotted solitons in two-component Ginzburg-Landau model are not described by a Faddeev-Skyrme-type model and are unstable. However these solitons can be stable at some intermediate length scales. I argue that configurations with a high topological charge may be more stable in this system than low-topological-charge configurations. In the second part of the paper I discuss qualitatively different physics of the stability of knotted solitons in a more general Ginzburg-Landau model and point out the physically relevant terms which enhance or suppress stability of the knotted solitons. With this argument it is demonstrated that the generalized Ginburg-Landau model possesses stable knotted solitons.
