description: 26.­­­  Phlegmariurus talamancanus ­­­  (B.Øllg.) B. Øllgaard (2012b: 19). Fig. 17
 Huperzia talamancana B. Øllgaard (1993: 67).—Type: Costa Rica, Prov. San José, Cordillera de Talamanca, Cerro de la Muerte, Pan American Hwy at km 91, Ericaceae-Chusquea scrub, 3000–3300 m, 25. Aug. 1983, Hickey 898, AAU, holotype).
 Erect from an ascending base, forming large clumps, sometimes up to 60 cm tall. Shoots homoblastic, homophyllous, equally thick throughout or slightly tapering, 7–15 (–25) mm in diam. incl. leaves. Stem excl. leaves 3–5 mm thick. Leaves borne in crowded, irregular, alternating whorls of (4–) 5–7, spreading to arcuately ascending or loosely imbricate, lanceolate, (6–) 8–11 × 2–3 mm (leaves of distal divisions sometimes 1.5–2 mm wide), with an inconspicuous to prominent, often prominently decurrent basal swelling (air cavity), abaxially flat to rounded or with a shallow central ridge, smooth and often lustrous, sometimes with a few inconspicuous, slightly protruding, blister-like epidermal cells, with irregularly protruding, clear, marginal cells, green or yellowish tinged, not pruinous. Sporangia 2–3 mm wide.
 ­­­ Distribution:— Costa Rica and Panamá. Endemic.
 ­­­ Habitats:—Terrestrial in páramo, and under scrub. 2500–3380 m elev.
 ­­­ Notes:—A variable species, responding strongly to the light conditions of its habitats. Apparently related to Phlegmariurus crassus, with which it has often been confused.
 This species grows as a terrestrial plant in páramo, and under open scrub in páramo, in marshes and high swamps, often associated with Sphagnum. It appears to be rather frequent at high altitudes, mainly above 3,000 m in Costa Rica, and is known from two localities in western Panamá. Phlegmarius talamancanus often coexists with P. crassus in Costa Rica. It belongs to the Phlegmarius crassus group (Testo et al. 2018b) and has commonly been included in a wide concept of Phlegmariurus saururus (as Lycopodium or Urostachys), see e. g. Lellinger (1989).
 ­­­ Specimens­­­studied:—Bocas­­­del­­­Toro: Between Itamut and Bine peaks, Fábrega Massif, 3200 m, Gómez et al. 22529 (AAU, MO, UC). Chiriquí: Volcán de Chiriquí, Loma Larga to summit, 2500–3380 m, Woodson et al. 1079 (GH, MO, NY, US).

description: In dieser Bachelorarbeit geht es um die Entstehung, die Involvierten und die Behandlung von Mobbing in der Schule durch die Soziale Arbeit. Durch Mobbing wird an den Schulen eine bestimmte Form von Gewalt ausgeübt. Betroffene Jugendliche trauen sich oftmals nicht, sich den Erziehungsberechtigten oder den Sozialarbeitenden in der Schule anzuvertrauen. Die Fachpersonen innerhalb des Systems Schule sollen dem Phänomen Mobbing mit professionellen Vorgehensmethoden begegnen können. Im Rahmen einer Literaturrecherche sind die Autoren Josef Nogueira und Lukas Teixeira Ferreira der Fragestellung Wie können systemische und lösungsorientierte Vorgehensmethoden in der Beratung mit Jugendlichen in der Schule auf das Thema Mobbing angewandt werden? nachgegangen. Mit der Beschreibung und Definition der Begriffe Jugendliche, Mobbing und Soziale Arbeit in der Schule wurde eine theoretische Basis für diese Bachelorarbeit geschaffen. Im Anschluss wurden die Entstehung des Phänomens Mobbing und die Interventionsmöglichkeiten in der Beratung dargelegt. Damit die systemischen und lösungsorientierten Mobbinginterventionsmethoden der Sozialen Arbeit auf Jugendliche in der Schule angewandt werden können, benötigt es in der Schule Sozialarbeitende, welche die Kernkompetenzen der Sozialen Arbeit besitzen. Zudem sollen sämtliche im Mobbingprozess beteiligten Rollen partizipativ in die Lösungsfindung involviert werden. Weiter muss jeder Fall individuell betrachtet werden. Es dürfen keine Pauschalisierungen vorgenommen werden, da die involvierten Jugendlichen nicht alle in derselben Entwicklungsstufe sind und somit mit einer Intervention durch Sozialarbeitende jeweils andere Bedürfnisse gestillt werden müssen.

description: We present an analytic enumeration of the metastable states, $N_s$, in a periodic long-range Josephson array frustrated by a transverse field. We find that the configurational entropy, $S_{conf} \equiv \ln N_s$, is extensive and scales with frustration, confirming that the non-random system is glassy. We also find that $S_{conf}$ is different from that of its disordered analogue, despite that fact that the two models share the same dynamical equations.

description: Temporal graphs represent binary relationships that change along time. They can model the dynamism of, for example, social and communication networks. Temporal graphs are defined as sets of contacts that are edges tagged with the temporal intervals when they are active. This work explores the use of the Compressed Suffix Array (CSA), a well-known compact and self-indexed data structure in the area of text indexing, to represent large temporal graphs. The new structure, called Temporal Graph CSA (TGCSA), is experimentally compared with the most competitive compact data structures in the state-of-the-art, namely, EDGELOG and CET. The experimental results show that TGCSA obtains a good space-time trade-off. It uses a reasonable space and is efficient for solving complex temporal queries. Furthermore, TGCSA has wider expressive capabilities than EDGELOG and CET, because it is able to represent temporal graphs where contacts on an edge can temporally overlap.

description: Reaction currents in chemical networks usually increase when increasing their driving affinities. But far from equilibrium the opposite can also happen. We find that such negative differential response (NDR) occurs in reaction schemes of major biological relevance, namely, substrate inhibition and autocatalysis. We do so by deriving the full counting statistics of two minimal representative models using large deviation methods. We argue that NDR implies the existence of optimal affinities that maximize the robustness against environmental and intrinsic noise at intermediate values of dissipation. An analogous behavior is found in dissipative self-assembly, for which we identify the optimal working conditions set by NDR.

description: Using molecular dynamics simulations, with a realistic many-body embedded-atom potential, and a novel method to characterize local order, we study the structure of pure nickel during the rapid quench of the liquid and in the resulting glass. In contrast with previous simulations with pair potentials, we find more crystalline order and fewer icosahedra for slower quenching rates, resulting in a glass less stable against crystallization. It is shown that there is not a specific amorphous structure, only the arrest of the transition from liquid to crystal, resulting in small crystalline clusters immersed in an amorphous matrix with the same structure of the liquid.

description: This article presents the main results obtained in the pilot test of an experimental study on the acquisition of cultural competence in translator training. This study is part of PACTE’s (Process in the Acquisition of Translation Competence and Evaluation) research into the acquisition of translation competence. The research design of this study was pilot tested with a sample of five trainee translators in the final year of the degree in Translation and Interpreting at the Universitat Autònoma de Barcelona. Subjects’ L2 was German, and Spanish or Catalan was their native language. Data was gathered to test the suitability of the sample selection criteria, the translation problems that were selected for deeper analysis, the performance of the data collection instruments and the length and order of the experimental tasks. Results show that the data collection instruments gathered relevant data, the selected sample was drawn from a normal population and that the translation problems selected for deeper analysis were suitable. However, the experimental tasks have to be revised and more data on cultural aspects has to be collected.
En este artículo se presentan los principales resultados del estudio piloto de un estudio experimental sobre la adquisición de la competencia cultural en la formación de traductores. Este estudio se enmarca en la investigación sobre adquisición de la competencia traductora del Grupo PACTE (Proceso de Adquisición de la Competencia Traductora y Evaluación). El diseño experimental del estudio se pilotó con una muestra de cinco estudiantes con alemán como segunda lengua extranjera del último curso del Grado en Traducción e Interpretación de la Universitat Autònoma de Barcelona. La lengua materna de los estudiantes era el español o el catalán. Se recogieron datos para comprobar la adecuación de los criterios de selección de la muestra, la idoneidad de los problemas de traducción seleccionados para el análisis, el funcionamiento de los instrumentos de recogida de datos y la duración y el orden de las tareas experimentales. Los resultados han demostrado que los instrumentos recogen datos pertinentes, la muestra seleccionada era representativa de la población de estudio y los problemas de traducción eran útiles para el análisis. Sin embargo, las tareas experimentales deben ser revisadas y deben recogerse más datos sobre aspectos culturales.

description: The Survey of Ionized Gas of the Galaxy, Made with the Arecibo telescope (SIGGMA) provides a fully-sampled view of the radio recombination line (RRL) emission from the portion of the Galactic plane visible by Arecibo. Observations use the Arecibo L-band Feed Array (ALFA), which has a FWHM beam size of 3.4 arcmin. Twelve hydrogen RRLs from H163$α$ to H174$α$ are located within the instantaneous bandpass from 1225 MHz to 1525 MHz. We provide here cubes of average ("stacked") RRL emission for the inner Galaxy region $32 \le \ell \le 70$ degrees, $|b|\le1.5$ degree, with an angular resolution of 6 arcmin. The stacked RRL rms at 5.1 km/s velocity resolution is $\sim0.65$ mJy beam$^{-1}$, making this the most sensitive large-scale fully-sampled RRL survey extant. We use SIGGMA data to catalogue 319 RRL detections in the direction of 244 known HII regions, and 108 new detections in the direction of 79 HII region candidates. We identify 11 Carbon RRL emission regions, all of which are spatially coincident with known HII regions. We detect RRL emission in the direction of 14 of the 32 supernova remnants (SNRs) found in the survey area. This RRL emission frequently has the same morphology as the SNRs. The RRL velocities give kinematic distances in agreement with those found in the literature, indicating that RRLs may provide an additional tool to constrain distances to SNRs. Finally, we analyze the two bright star-forming complexes: W49 and W51. We discuss the possible origins of the RRL emission in directions of SNRs W49B and W51C.

description: We discuss the appearance of additional, hidden supersymmetries for simple 0+1 $Ad(G)$-invariant supersymmetric models and analyse some geometrical mechanisms that lead to them. It is shown that their existence depends crucially on the availability of odd order invariant skewsymmetric tensors on the (generic) compact Lie algebra $\cal G$, and hence on the cohomology properties of the Lie algebra considered.

Abnormal CD1611 immune cells and retinoic acid receptor–related orphan receptor gt–mediate enhanced IL-17F expression in the setting of genetic hypertension

description: Background: Hypertension is considered an immunologic
disorder. However, the role of the IL-17 family in genetic
hypertension in the spontaneously hypertensive rat (SHR) has
not been investigated.
Objective: We tested the hypothesis that enhanced TH17
programming and IL-17 expression in abundant CD1611
immune cells in SHRs represent an abnormal proinflammatory
adaptive immune response. Furthermore, we propose that this
response is driven by the master regulator retinoic acid
receptor–related orphan receptor gt (RORgt) and a nicotinic
proinflammatory innate immune response.
Methods: We measured expression of the CD161 surface
marker on splenocytes in SHRs and normotensive control
Wistar-Kyoto (WKY) rats from birth to adulthood. We
compared expression of IL-17A and IL-17F in splenic cells
under different conditions. We then determined the functional
effect of these cytokines on vascular reactivity. Finally, we tested
whether pharmacologic inhibition of RORgt can attenuate
hypertension in SHRs.
Results: SHRs exhibited an abnormally large population of
CD1611 cells at birth that increased with age, reaching more
than 30% of the splenocyte population at 38 weeks. The SHR
splenocytes constitutively expressed more RORgt than those of
WKY rats and produced more IL-17F on induction. Exposure
of WKY rat aortas to IL-17F impaired endothelium-dependent
vascular relaxation, whereas IL-17A did not. Moreover, in vivo inhibition of RORgt by digoxin decreased systolic blood
pressure in SHRs.
Conclusions: SHRs have a markedly enhanced potential for
RORgt-driven expression of proinflammatory and
prohypertensive IL-17F in response to innate immune
activation. Increased RORgt and IL-17F levels contribute to
SHR hypertension and might be therapeutic targets.

Are there narrow flavor-exotic tetraquarks in large-$N_c$ QCD?

description: A salient feature shared by all tetraquark candidates observed in experiment is the absence of flavor-exotic states of the type $\bar a b\bar c d$, with four different quark flavors. This phenomenon may be understood from the properties of large-$N_c$ QCD: On the one hand, consistency conditions for flavor-exotic Green functions, potentially containing these tetraquark poles, require the existence of two tetraquarks $T_A$ and $T_B$: each of them should decay dominantly via a single two-meson channel, $T_A\to M_{\bar a b}M_{\bar c d}$ and $T_B\to M_{\bar a d}M_{\bar c b}$, with suppressed rates $T_A\to M_{\bar a d}M_{\bar c b}$ and $T_B\to M_{\bar a b}M_{\bar c d}$. On the other hand, we have at hand only one diquark-antidiquark flavor structure $(\bar a \bar c)(b d)$ that might produce a compact tetraquark bound state. Taking into account that the diquark-antidiquark structure is the only viable candidate for a compact tetraquark state, one concludes that it is impossible to have two different narrow tetraquarks decaying dominantly into different two-meson channels. This contradiction suggests that large-$N_c$ QCD does not support the existence of narrow flavor-exotic tetraquarks. This argument does not rule out the possible existence of broad molecular-type flavor-exotic states, or of molecular-type bound states lying very close to the two-meson thresholds.

Mean-field study of the interplay between antiferromagnetism and d-wave superconductivity

description: The interplay between antiferromagnetism and d-wave superconductivity is studied in a mean-field approximation for a generic microscopic Hamiltonian with short-range repulsion and near-neighbor attraction. In the presence of competing microscopic interactions, the phase boundaries of antiferromagnetic and superconducting states are significantly modified in some region of the doping-temperature plane. The transition between superconductivity and antiferromagnetism occurs through a phase where both order parameters coexist with a third, dynamically generated, spin-triplet amplitude. This dynamical generation of a new order parameter is not restricted to a system with antiferromagnetism and d-wave superconductivity, but is a generic feature for fermionic systems. The dynamically generated spin-triplet order parameter is found to be robust to variations in the mean-field Hamiltonian.

description: Arbeit sichert Autonomie und schützt vor Armut. Das Paradigma der Aktivierung, das sich seit den 1990er Jahren im schweizerischen Sozialstaat etabliert hat, soll früh und umfassend jungen Erwachsenen Unterstützung auf dem Weg in die Arbeitswelt ermöglichen. Verschiedene Arbeitsintegrationsprogramme haben sich seither etabliert und werden von den Sozialversicherungen und der Sozialhilfe als Mittel genutzt, um den Weg in den Arbeitsmarkt zu ermöglichen. Trotz den Bemühungen gelingt der Einstieg in eine Berufslehre und nachher die Loslösung von der Sozialhilfe nicht Allen. Die vorliegende Arbeit beleuchtet mittels Literaturrecherche zunächst theoretische Grundlagen, welche eine berufliche Integration von sozialhilfebeziehenden jungen Erwachsenen ohne Berufslehre beeinflussen. Dabei zeigen sich diverse Hindernisse aus Sicht der Berufswahlbereitschaft, aus entwicklungspsychologischer, lebensweltorientierter und motivationstheoretischer Sicht. Bei der anschliessenden Auseinandersetzung mit dem Auftrag der Arbeitsintegration als Berufsfeld der Sozialen Arbeit zeigt sich ein Spannungsfeld, das systemtheoretisch unterlegt wird und aufzeigt, dass die Rolle der Wirtschaft ausser Acht gelassen wird. Bei der Erarbeitung der einzelnen Themen haben sich für die Autorinnen Erkenntnisse ergeben, die schliesslich aus Sicht der Menschenrechtsprofession der Sozialen Arbeit bewertet werden. Die Bewertung zeigt, dass die Arbeitsintegration Lücken aufweist, die unter den gegebenen Umständen auch exkludierend wirken können. Der Schluss widmet sich möglichen Umsetzungen des Integrationsauftrages der Sozialen Arbeit im Berufsfeld der Arbeitsintegration und zeigt Handlungsalternativen auf.

description: Latest observational reports of solar flares reveal some uncommon features of microwave spectra, such as unusually hard (or even positive) spectra, and/or a super-high peak frequency. For a better understanding of these features, we conduct a parameter study to investigate the effect of broken-power-law spectra of energetic electrons on microwave emission on the basis of gyrosynchrotron mechanism. The electron broken-power-law energy distribution is characterized by three parameters, the break energy ($E_B$), the power-law indices below ($δ_1$) and above ($δ_2$) the break energy. We find that with the addition of the $δ_2$ component of the electron spectra, the total flux density can increase by several times in the optically-thick regime, and by orders of magnitude in the optically-thin regime; the peak frequency ($ν_p$) also increases and can reach up to tens of GHz; and the degree of polarization ($r_c$) decreases in general. We also find that (1) the variation of the flux density is much larger in the optically-thin regime, and the microwave spectra around the peak frequency manifest various profiles with the softening or soft-hard pattern; (2) the parameters $δ_1$ and $E_B$ affect the microwave spectral index ($α$) and the degree of polarization ($r_c$) mainly in the optically-thick regime, while $δ_2$ mainly affects the optically-thin regime. The results are helpful in understanding the lately-reported microwave bursts with unusual spectral features and point out the demands for a more-complete spectral coverage of microwave bursts, especially, in the high-frequency regime, say, $>10-20$ GHz.

description: The design of multi-target directed ligands (MTDLs) is a valid approach for obtaining effective drugs for complex pathologies. MTDLs that combine neuro-repair properties and block the first steps of neurotoxic cascades could be the so long wanted remedies to treat neurodegenerative diseases (NDs). By linking two privileged scaffolds with well-known activities in ND-targets, the flavonoid and the N,N-dibenzyl(N-methyl)amine (DBMA) fragments, new CNS-permeable flavonoid – DBMA hybrids (1–13) were obtained. They were subjected to biological evaluation in a battery of targets involved in Alzheimer’s disease (AD) and other NDs, namely human cholinesterases (hAChE/hBuChE), β-secretase (hBACE-1), monoamine oxidases (hMAO-A/B), lipoxygenase-5 (hLOX-5) and sigma receptors (σ1R/σ2R). After a funnel-type screening, 6,7-dimethoxychromone – DBMA (6) was highlighted due to its neurogenic properties and an interesting MTD-profile in hAChE, hLOX-5, hBACE-1 and σ1R. Molecular dynamic simulations showed the most relevant drug-protein interactions of hybrid 6, which could synergistically contribute to neuronal regeneration and block neurodegeneration.

description: We present theoretically the thermal Hall effect of magnons in a ferromagnetic lattice with a Kekulé-O coupling (KOC) modulation and a Dzyaloshinskii-Moriya interaction (DMI). Through a strain-based mechanism for inducing the KOC modulation, we identify four topological phases in terms of the KOC parameter and DMI strength. We calculate the thermal magnon Hall conductivity ${κ^{xy}}$ at low temperature in each of these phases. We predict an unconventional conductivity due to a non-zero Berry curvature emerging from band proximity effects in the topologically trivial phase. We find sign changes of ${κ^{xy}}$ as a function of the model parameters, associated with the local Berry curvature and occupation probability of the bulk bands. Throughout, ${κ^{xy}}$ can be easily tuned with external parameters such as the magnetic field and temperature.

 Lycopodium tenue Willdenow (1810: 55).— Huperzia tenuis (Willdenow) Trevisan (1874: 248).— Urostachys tenuis (Willdenow) Nessel (1927: 401). Type:— ECUADOR. Loja: Valley of Vinajacu, near Loja, Humboldt & Bonpland 3363 (B-Willdenow no. 19423 holotype; BM, LG, P00669229 isotypes).
 Usually epiphytic, delicate to extremely delicate, flaccidly pendulous, at least to 75 cm long. Shoots gradually heterophyllous, 3–8 mm in diameter including the leaves in the basal divisions, tapering to 1–3 mm in diameter in the narrow terminal divisions. Stems excluding leaves 0.5–0.7 mm thick at the base, tapering to ca. 0.3 mm upward, pale greenish to stramineous, at least to 10 times dichotomous, usually discontinuously and unilaterally sporangiate from 10–30 cm above the base and upward. Leaves of basal divisions borne in irregular alternating whorls of 3–5, or spirally arranged, forming 6–10 indistinct longitudinal ranks, usually densely crowded, spreading to ascending, straight to somewhat curved, often secund, acicular, tapering from a subauriculate base, 3–5 (–7) × 0.3–0.5 mm, decurrent. Vegetative leaves and sporophylls of constricted terminal divisions almost conform, borne in alternating irregular whorls of 3, or irregularly alternate, patently diverging from the stem, with upward curved tips, widely ovate to subhastate, 1–3 × 0.5–1.4 mm wide at the base, clasping with the base, tapering to abruptly narrowed into a short to long acuminate apex, bluntly to sharply carinate, usually unilaterally, discontinuously, but often densely sporangiate. Sporangia 0.8–1.2 mm wide.
 ­­­ Distribution:— Costa Rica, Panamá, Andes from Venezuela to Bolivia.
 Habitats:— Epiphytic in uppermost montane forests, elev. 2800–3500 m elev.
 Notes:— Phlegmariurus tenuis exhibits the same type of size variation as mentioned for P. curvifolius. Some forms are almost as extremely fragile and slender but are easily distinguished by the spreading leaves in the terminal divisions. This species is also ecologically distinct, being restricted to the uppermost montane forests. The Central American plants are generally larger and more robust than the Andean ones.

description: Steady-state properties of microemulsions in shear flow are studied in the context of a Ginzburg-Landau free-energy approach. Explicit expressions are given for the structure factor and the time correlation function at the one loop level of approximation. Our results predict a four-peak pattern for the structure factor, implying the simultaneous presence of interfaces aligned with two different orientations. Due to the peculiar interface structure a non-monotonous relaxation of the time correlator is also found.

description: Here are presented the experimental results obtained with a ferrofluidic deformable mirror controlled by electro-magnet actuators. Using a step input through a single actuator we obtain a steady-state settling time of 100ms; however, different combinations of overdrive inputs can be used to decrease it to 25ms. Also, a new technique which consists in laying down an elastomer membrane, coated with an aluminum film, on the ferrofluid is discussed. By adding the membrane on the ferrofluid, it further decreases the time response by a factor of 2. Furthermore, the thin aluminum layer improves the reflectivity of the mirror. Finally, using the membrane and the overdrive techniques combined, the time response is improved by a factor of 20. Numerical simulations show that ferrofluidic mirrors using membranes and improved electronics should reach settling times of the order of a millisecond. Presumably even lower settling times could be possible.

Possible Stratification Mechanism in Granular Mixtures

description: We propose a mechanism to explain what occurs when a mixture of grains of different sizes and different shapes (i.e. different repose angles) is poured into a quasi-two-dimensional cell. Specifically, we develop a model that displays spontaneous stratification of the large and small grains in alternating layers. We find that the key requirement for stratification is a difference in the repose angles of the two pure species, a prediction confirmed by experimental findings. We also identify a kink mechanism that appears to describe essential aspects of the dynamics of stratification.

Comments on fractional instantons in N=2 gauge theories

subject: FOS: Physical sciences

description: N=1^* gauge theories are believed to have fractional instanton contributions in the confining vacua. D3 brane probe computations in gravitation dual of large-N N=2^* gauge theories point to the absence of such contributions in the low energy gauge dynamics. We study fractional instantons in N=2 SU(2) Yang-Mills theory from the field theoretical perspective. We present new solutions to the Seiberg-Witten SU(2) monodromy problem with the same perturbative asymptotic, a massless monopole and a dyon singularity on the moduli space, and fractional instanton corrections to N=2 prepotential in the semi-classical region of the moduli space. We show that fractional instantons lead to infinite monopole (dyon) condensate in mass deformed N=2 gauge theories.

Conductance oscillations in mesoscopic rings: microscopic versus macroscopic picture

description: The phase of Aharonov-Bohm oscillations in mesoscopic metal rings in the presence of a magnetic field can be modulated by application of a DC-bias current I_DC. We address the question of how a variation of I_DC and hence of the microscopic phases of the electronic wave functions results in the macroscopic phase of the conductance oscillations. Whereas the first one can be varied continuously the latter has to be quantized for a ring in two-wire configuration by virtue of the Onsager symmetry relations. We observe a correlation between a phase flip by +/- pi and the amplitude of the oscillations.

Modified BCS mechanism of Cooper pair formation in narrow energy bands of special symmetry I. Band structure of niobium
Creators: name: Krüger, Ekkehard
Publisher: name: arXiv
Year: 2000
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The superconductor niobium possesses a narrow, roughly half-filled energy band with Bloch functions which can be unitarily transformed into optimally localized spin-dependent Wannier functions belonging to a double-valued representation of the space group of Nb. The special symmetry of this "superconducting band" can be interpreted within a nonadiabatic extension of the Heisenberg model of magnetism. While the original Heisenberg model assumes that there is exactly one electron at each atom, the nonadiabatic model postulates that the Coulomb repulsion energy in narrow, partly filled energy bands is minimum when the balance between the bandlike and atomiclike behavior is shifted as far as possible towards the atomiclike behavior. Within this nonadiabatic Heisenberg model, the electrons of the superconducting band form Cooper pairs at zero temperature. Just as in the BCS theory of superconduc- tivity, this formation of Cooper pairs is mediated by phonons. However, there is an important difference: within the nonadiabatic Heisenberg model, the electrons in a narrow superconducting band are constrained to form Cooper pairs because the conservation of spin angular momentum would be violated in any normal conducting state. There is great evidence that these constraining forces are responsible for superconducting eigenstates. That means that an attractive electron-electron interaction alone is not able to produce stable Cooper pairs. In addition, the constraining forces established within the nonadiabatic Heisenberg model must exist in a superconductor.

Detailed X-Ray Mapping of the Shocked Ejecta and Circumstellar Medium in the Galactic Core-Collapse Supernova Remnant G292.0+1.8

description: G292.0+1.8 (G292) is a young ($\sim$3000 yr), Galactic textbook-type core-collapse supernova remnant (CCSNR). It is characterized by X-ray, optical and infrared emission from ejecta and circumstellar medium (CSM) features, and contains a pulsar (PSR J1124-5916) and pulsar wind nebula that have been observed in X-rays and radio. Previous studies have revealed a complex, dynamically evolving, oxygen-rich remnant, a striking relic from the explosion of a massive star. Here, using our deep (530 ks) $\textit{Chandra}$ ACIS data, we present high spatial-resolution maps (based on a regional grid size of a few arcsec) of the shocked CSM and metal-rich ejecta in G292. We make the first $\textit{Chandra}$-detection of Fe-rich ejecta in G292. We identify the X-ray counterpart of the northern equatorial belt, a component of a ring-like CSM structure identified earlier in the infrared band. We show the detailed spatial distributions of ejecta enriched in O, Ne, Mg, Si, S and Fe. We find that the bulk of the Si, S and Fe-rich X-ray-emitting ejecta are located in the northwestern hemisphere of the remnant, opposite to the pulsar's projected angular displacement to the southeast from the SNR's center. This suggests that the pulsar's kick may have originated from gravitational and hydrodynamic forces during an asymmetric explosion, rather than from anisotropic neutrino emission. Based on abundance ratios and our estimated CSM and ejecta masses, we constrain the progenitor mass to 13 M$_{\odot}$ $\lesssim$ M $\lesssim$ 30 M$_{\odot}$

Continuous Avalanche Segregation of Granular Mixtures in Thin Rotating Drums

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study segregation of granular mixtures in the continuous avalanche regime (for frequencies above ~ 1 rpm) in thin rotating drums using a continuum theory for surface flows of grains. The theory predicts profiles in agreement with experiments only when we consider a flux dependent velocity of flowing grains. We find the segregation of species of different size and surface properties, with the smallest and roughest grains being found preferentially at the center of the drum. For a wide difference between the species we find a complete segregation in agreement with experiments. In addition, we predict a transition to a smooth segregation regime - with an power-law decay of the concentrations as a function of radial coordinate - as the size ratio between the grains is decreased towards one.

description: The realization of center and chiral symmetries in $\mathcal{N}=1$ super Yang-Mills theory (SYM) is investigated on a four-dimensional Euclidean lattice by means of Monte Carlo methods. At zero temperature this theory is expected to confine external fundamental charges and to have a non-vanishing gaugino condensate, which breaks the non-anomalous Z$_{2\textrm{N}_{c}}$ chiral symmetry. In previous studies at finite temperatures, the phase transitions corresponding to deconfinement and chiral restoration were observed to occur at roughly the same critical temperature for SU(2) gauge group. We find further evidences for this observation from new measurements at smaller lattice spacings using the fermion gradient flow, and we discuss the agreement of our findings with conjectures from superstring theory. The implementation of the gradient flow technique allows us also to estimate, for the first time, the condensate at zero temperatures and zero gaugino mass with Wilson fermions.
