description: Ground state properties and excited states of ladder-type paraphenylene oligomers are calculated applying semiempirical methods for up to eleven phenylene rings. The results are in qualitative agreement with experimental data. A new scheme to interpret the excited states is developed which reveals the excitonic nature of the excited states. The electron-hole pair of the S1-state has a mean distance of approximately 4 Angstroem.

description: The Middle Jurassic docodont Borealestes serendipitus was the first Mesozoic mammal found in Scotland over 40 years ago. Its affinities and morphology have remained poorly understood. Although multiple dentary fragments and isolated teeth have been recovered from Scotland and England, they have not yet been described in sufficient detail. We report new, more complete specimens collected during recent field work on Skye, Scotland, combined with previously collected material. This includes upper and lower dentition and an almost complete right dentary. We present an updated description and diagnosis of the genus Borealestes, based on high-resolution micro-computed tomography (micro-CT) and synchrotron scans. We identify seven key features that distinguish Borealestes from other docodonts, including a pronounced a–c crest, absence of the a–g crest on cusp a, an anterior fovea at the buccolingual midpoint of the upper molar, and the convergence of the Meckel’s groove with the ventral margin of the mandible. We also present a revised diagnosis for the second species, B. mussettae. Our phylogenetic analysis supports a clade formed by Borealestes, Haldanodon, Docofossor, and Docodon. Ontogenetic variation in the mandibular morphology of Borealestes is similar to that seen in Docodon and Haldanodon, with the delayed emergence of the ultimate lower molar, the shift of the last molar to the front of the coronoid process, and a posterior shift of the Meckel’s sulcus in successively older individuals. This supports a distinctive growth pattern in the clade including Borealestes and Docodon, one that may be present in Docodonta as a whole.

description: Numerical renormalization-group results on entropy of the anisotropic two-channel Kondo model with the band-width cutoff ($D$) in the presence of a magnetic field ($h$) are obtained to determine crossover temperature from the non-Fermi liquid to Fermi liquid fixed point. It is found that the crossover temperature ($T_{\rm x}$) is given by $T_{\rm x} \equiv {r} T_{\rm K} \sim D(ΔJ/J_{\rm av})^2 e^{-1/J_{\rm av}}$ when $(h /T_{\rm K})^2 \ll r \ll 1 $, where $T_{\rm K}$, $J_{\rm av}$ and $ΔJ$ are the Kondo temperature, the average and difference of the exchange coupling constants, respectively. This result indicates that non-Fermi liquid behavior can be seen even if $ΔJ > T_{\rm K}$. Robust similarities of the crossover behavior in the region around the non-Fermi liquid critical point to that of the two-impurity Kondo model are also discussed.

 Drassus scrutatus O. Pickard-Cambridge 1872: 239, plate 15, fig. 16a (♂ ♀) (for a complete list of references, see World Spider Catalog 2020).
 Herpyllus bicolor Tikader, 1982: 458, figs 368–371 (♀) (erroneous transfer of Melicymnis bicolor Simon, 1885, based on misidentified specimen, apparently not the type of M. bicolor).
 Remarks
 Tikader (1982) illustrated a Herpyllus species, ‘ Herpyllus bicolor ’, erected by transferring the type species of Melicymnis Simon, 1885 (currently considered as nomen dubium) (World Spider Catalog 2020) without any explanation assuming that the specimen he studied was that of the type. The type species of Melicymnis, Melicymnis bicolor Simon, 1885 is, in fact, a juvenile specimen and has a different somatic morphology in comparison with that of ‘ H. bicolor ’ (compare Murphy 2007, fig. 594 with Tikader 1982, fig. 368), indicating that Tikader’s illustrations are based on a misidentified specimen. The illustrations clearly indicate that it is Z. scrutatus as it has a narrow continuous anterior epigynal margin, epigyne with longitudinal dropletlike median depression, long highly coiled internal ducts and globular spermathecae (Tikader 1982, figs 369–370). There is a possibility that Tikader (1982) might have chosen, by misidentification, the specimen of Z. scrutatus found in the same vial along with the juvenile type of M. bicolor received from MNHN and described and illustrated it as ‘ H. bicolor ’. Therefore, the specimen identified as ‘ H. bicolor ’ is actually misidentified and does not pertain to that of M. bicolor.

The simulations are carried out on a subset of the (isospin symmetric) $N_f=2+1$ flavour Coordinated Lattice Simulations (CLS) gauge ensembles with lattice spacings ranging from $a\approx 0.086\,$fm down to $a\approx 0.050\,$fm. First results on the breaking of flavour symmetry and the low energy constants $F$ and $D$ are presented. While SU(3) flavour symmetry violations are found to be sizeable for $g_A=\langle 1\rangle_{Δu^+-Δd^+}$, these are quite small for $g_T=\langle 1\rangle_{δu^--δd^-}$ and $\langle x\rangle_{u^+-d^+}$.

description: We study the optimisation of exact renormalisation group (ERG) flows. We explain why the convergence of approximate solutions towards the physical theory is optimised by appropriate choices of the regularisation. We consider specific optimised regulators for bosonic and fermionic fields and compare the optimised ERG flows with generic ones. This is done up to second order in the derivative expansion at both vanishing and non-vanishing temperature. We find that optimised flows at finite temperature factorise. This corresponds to the disentangling of thermal and quantum fluctuations. A similar factorisation is found at second order in the derivative expansion. The corresponding optimised flow for a ``proper-time renormalisation group'' is also provided to leading order in the derivative expansion.

description: The conductance of disordered nano-wires at T=0 is calculated in one-particle approximation by reducing the original multi-dimensional problem for an open bounded system to a set of exactly one-dimensional non-Hermitian problems for mode propagators. Regarding two-dimensional conductor as a limiting case of three-dimensional disordered quantum waveguide, the metallic ground state is shown to result from its multi-modeness. On thinning the waveguide (in practice, e. g., by means of the ``pressing'' external electric field) the electron system undergoes a continuous phase transition from metallic to insulating state. The result predicted conform qualitatively to the observed anomalies of the resistance of different planar electron and hole systems.

description: A concept -- quantum order -- is introduced to describe a new kind of orders that generally appear in quantum states at zero temperature. Quantum orders that characterize universality classes of quantum states (described by {\em complex} ground state wave-functions) is much richer then classical orders that characterize universality classes of finite temperature classical states (described by {\em positive} probability distribution functions). The Landau's theory for orders and phase transitions does not apply to quantum orders since they cannot be described by broken symmetries and the associated order parameters. We find projective representations of symmetry groups (which will be called projective symmetry groups) can be used to characterize quantum orders. With the help of quantum orders and the projective symmetry groups, we construct hundreds of symmetric spin liquids, which have SU(2), U(1) or $Z_2$ gauge structures at low energies. Remarkably, some of the stable quantum phases support gapless excitations even without any spontaneous symmetry breaking. We propose that it is the quantum orders (instead of symmetries) that protect the gapless excitations and make algebraic spin liquids and Fermi spin liquids stable. Since high $T_c$ superconductors are likely to be described by a gapless spin liquid, the quantum orders and their projective symmetry group descriptions lay the foundation for spin liquid approach to high $T_c$ superconductors.

description: Some of the operator product expansions (OPEs) between the lowest $SO(4)$ singlet higher spin-$2$ multiplet of spins $(2, \frac{5}{2}, \frac{5}{2}, \frac{5}{2}, \frac{5}{2}, 3, 3, 3, 3, 3, 3, \frac{7}{2}, \frac{7}{2}, \frac{7}{2}, \frac{7}{2}, 4)$ in an extension of the large ${\cal N}=4$ (non)linear superconformal algebra were constructed in the ${\cal N}=4$ superconformal coset $\frac{SO(N+4)}{SO(N) \times SO(4)}$ theory with $N=4$ previously. In this paper, by rewriting the above OPEs with $N=5$, the remaining undetermined OPEs are completely determined. There exist additional $SO(4)$ singlet higher spin-$2$ multiplet, six $SO(4)$ adjoint higher spin-$3$ multiplets, four $SO(4)$ vector higher spin-$\frac{7}{2}$ multiplets, $SO(4)$ singlet higher spin-$4$ multiplet and four $SO(4)$ vector higher spin-$\frac{9}{2}$ multiplets in the right hand side of these OPEs. Furthermore, by introducing the arbitrary coefficients in front of the composite fields in the right hand sides of the above complete 136 OPEs, the complete structures of the above OPEs are obtained by using various Jacobi identities for generic $N$. Finally, we describe them as one single ${\cal N}=4$ super OPE between the above lowest $SO(4)$ singlet higher spin-$2$ multiplet in the ${\cal N}=4$ superspace.

 Diagnosis (extended due to the incorporation of the new species). Large sized pselaphine of the tribe Ctenistini characterized by the following characters: 1) body shiny, dorsally with squamous setae restricted to base of head and base of pronotum; 2) head ventrally with belt of squamous setae except where interrupted by gular carina, additional squamous setae well-defined on mesoventrite, first (sternite III), and anterior and posterior parts of second (IV) abdominal ventrites; 3) head with very small frontal and vertexal foveae; 4) two pairs of trichomes present on apical corners of elytra; 5) antennal club trimerous, weakly defined, unmodified in males, scape and pedicel cylindrical, antennomeres III–X more or less conical, XI conical in basal half then taper to apex; 6) maxillary palpi varying from very small, not Epicaris could be seen as dubious. However, maxillary palpi are one of the most flexible and unstable body parts in the Pselaphinae. One of the evolutionary trends in the tribe Ctenistini seems to be towards diminution of the maxillary palpi (J. Parker, pers. comm. 2013). Four genera of Ctenistini have similarly reduced maxillary palpi, which are not visible in dorsal view: Chennium Latreille, 1807 (13 species in Palaearctic region from Spain to Turkmenistan and Uzbekistan), Chenniopsis Raffray, 1904 (1 species from Madagascar), Atinus Horn, 1868 (2 species from USA), and Biotus Casey, 1887 (1 species from USA). These genera, probably except for Chenniopsis, are myrmecophilous, which is also very probably the case of Epicaris due to the presence of trichomes on the elytra. Except for the form of the maxillary palpi, there are no other characters supporting the exclusion of E. bezdeki sp. nov. from Epicaris, and the diminution of the maxillary palpi of the three genera mentioned above, as well as in E. bezdeki sp. nov., could be simply a result of their adaptation to myrmecophily.

description: Extending previous results obtained in the effective-potential approach, we derive analytic expressions for the pole masses of the charged and neutral Higgs bosons in the minimal supersymmetric standard model (MSSM) with explicit CP violation. In such a minimal supersymmetric model, the CP invariance of the Higgs potential is explicitly broken by quantum effects dominated by third-generation squarks at the one-loop level and by one-loop gluino- and higgsino-mediated threshold corrections to the top- and bottom-quark Yukawa couplings at the two-loop level. Field-theoretic issues arising in the description of a two-level Higgs-boson system strongly mixed due to CP violation are addressed. Numerical results for the pole masses of the CP-violating Higgs bosons are presented, and comparisons are made with previous results obtained in the effective-potential approach.

The results obtained by projector quantum Monte Carlo simulations show that at moderate disorder, increasing the attractive interaction leads to a transition from delocalized superconducting states to the insulating phase of localized pairs. This transition takes place well within the metallic phase of the single-particle Anderson model.

Transmission of Monetary Policy in a Small Open Economy: Evidence from Mongolia

Subjects: subject: monetary policy

description: Monetary policy behaves in a forward-looking manner to influence the economy due to uncertainty and time lag of the effects of its policy actions. Therefore, the central bank’s ability to achieve the targeted goals is highly dependent on how reliable the transmission process is. This paper attempts to examine the effectiveness of monetary policy transmission mechanism in a small open economy, in the case of Mongolia. It employs a structural vector autoregression (VAR) model, which has a block exogeneity of a small open economy and uses two different identifications, the recursive and sign restrictions. The results suggest that the bank lending channel is the most effective transmission mechanism in Mongolia and operates as predicted by theory. We find that the interest rate channel works as influencing both price and output. The exchange rate has an immediate significant pass-through to price level; however, the effect on the real output is unclear. The effects of monetary policy shock on the interest rate and the exchange rate are sensitive to different identification schemes used. The transmission from monetary policy shock to interest rate is stronger in the recursive model but weaker in the sign restriction model. However, the transmission from monetary policy shock to exchange rate is weaker in the recursive model but stronger and persistent in the alternative model. Also, it is found that, with small open economy restrictions, the model resolves the exchange rate puzzle often found in small open economies.

description: This paper reports specific-heat measurements on superconducting MgB2 in magnetic fields to 9 T. In zero magnetic field the data can be fitted to a two-gap model, which is a generalization of a semi-empirical model for strong-coupled, single-gap superconductors (the alpha-model), to within the precision of the data. Both gaps close at Tc, with one gap larger and one smaller than the BCS weak-coupling-limit. (The two gaps have a ratio ~ 4:1.) Each gap accounts for ~ 50% of the normal electron density of states. The parameters characterizing the fits agree well with those from recent spectroscopic measurements and theory. In magnetic fields the superconductong anomaly is broadened as expected for an anisotropic, randomly-oriented superconductor.

description: Naucleoffieine H, a natural indole alkaloid, was isolated and identified from Nauclea officinalis Pierrc ex Pitard which is a traditional Chinese medicine used for the treatment of various diseases, such as cold, fever, bronchitis, pneumonia, acute tonsillitis, etc. In the present study, the effect of naucleoffieine H on the anti-inflammatory activities was investigated in LPS-induced RAW 264.7 macrophages. The results showed that naucleoffieine H significantly inhibited the release of nitric oxide (the level of nitrite as a stable biomarker of NO production) and tumor necrosis factor-α (TNF-α). Interesting, naucleoffieine H down-regulated the overexpression of inflammatory protein induced nitric oxide synthase (iNOS), but no effect on the expression cyclooxygenase-2 (COX-2) protein. In addition, this bioactive alkaloid suppressed enzymatic activity of iNOS activated by LPS. The above results indicated that naucleoffieine H suppress NO and TNF-α overproduction via block the iNOS pathway in LPS-induced RAW 264.7 macrophages.

description: Age estimation techniques such as gyrochronology and magnetochronology can't be applied to stars that exchanged angular momentum with their close environment. This is especially true for massive close-in planetary companion (with a periods of few days or less), which could have been strongly impacted the rotational evolution of the host star, along the stellar evolution, through the star-planet tidal interaction. We showed that the interaction of a close-in massive planet with its host star can strongly modify the surface rotation rate of this latter, in most of the cases associated to a planetary engulfment. In such cases, a gyrochronology analysis of the star would wrongly make it appear as "rejuvenated", thus preventing us to use this method with confidence. To try overcome this issue, we eventually proposed the proof of concept of a new age determination technique that we call the tidal-chronology, which is based on the observed couple $\rm P_{rot,\star}$-$\rm P_{orb}$ of a given star-planet system. The gyrochronology technique can only be applied to isolated star or star-planet systems outside a specific range of $\rm P_{rot,\star}$-$\rm P_{orb}$. This region tends to expand for increasing stellar and planetary mass. In that forbidden region, or if any planetary engulfment is suspected, gyrochronology should be used with extreme caution while tidal-chronology could be considered. While this technique does not provide a precise age for the system yet, it is already an extension of gyrochronology and could be helpful to determine a more precise range of possible age for planetary system composed of a star between 0.3 and 1.2 $M_{\odot}$ and a planet more massive than 1 $\rm M_{jup}$ initially located at few hundredth au of the host star.

Flavour-Changing Neutral Currents and Leptophobic Z' Gauge Bosons

Year: 2001
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Leptophobic Z' gauge bosons can appear in models with an E_6 gauge symmetry. We show that flavour-changing neutral currents can be generated in some of these models due to the mixing of the ordinary d_R, s_R and b_R quark fields with the exotic h_R. Because the Z' does not couple to charged leptons, the constraints on the flavour-changing couplings U^{Z'}_{db} and U^{Z'}_{sb} are relatively weak. Indeed, B_q--Bbar_q mixing (q=d,s) can be dominated by Z' exchange, which will affect CP-violating rate asymmetries in B decays. Rare hadronic B decays can also be affected, while decays involving charged leptons will be unchanged.

description: Classical molecular-dynamics simulations have been carried out to investigate densification mechanisms in silicon dioxide thin films deposited on an amorphous silica surface, according to a simplified ion-beam assisted deposition (IBAD) scenario. We compare the structures resulting from the deposition of near-thermal (1 eV) SiO$_{2}$ particles to those obtained with increasing fraction of 30 eV SiO$_{2}$ particles. Our results show that there is an energy interval - between 12 and 15 eV per condensing SiO$_2$ unit on average - for which the growth leads to a dense, low-stress amorphous structure, in satisfactory agreement with the results of low-energy ion-beam experiments. We also find that the crossover between low- and high-density films is associated with a tensile to compressive stress transition, and a simultaneous healing of structural defects of the {\em a-}SiO$_2$ network, namely three- and four-fold rings. It is observed, finally, that densification proceeds through significant changes at intermediate length scales (4--10 Å), leaving essentially unchanged the ``building blocks'' of the network, viz. the Si(O$_{1/2}$)$_{4}$ tetrahedra. This latter result is in qualitative agreement with the mechanism proposed to explain the irreversible densification of amorphous silica recovered from high pressures ($\sim$ 15--20 GPa).

description: HD 142990 (V 913 Sco; B5 V) is a He-weak star with a strong surface magnetic field and a short rotation period ($P_{\rm rot} \sim 1$ d). While it is clearly a rapid rotator, recent determinations of $P_{\rm rot}$ are in formal disagreement. In this paper we collect magnetic and photometric data with a combined 40-year baseline in order to re-evaluate $P_{\rm rot}$ and examine its stability. Both period analysis of individual datasets and $O-C$ analysis of the photometric data demonstrate that $P_{\rm rot}$ has decreased over the past 30 years, violating expectations from magnetospheric braking models, but consistent with behaviour reported for 2 other hot, rapidly rotating magnetic stars, CU Vir and HD 37776. The available magnetic and photometric time series for HD 142990 can be coherently phased assuming a spin-up rate $\dot{P}$ of approximately $-0.6$ s/yr, although there is some indication that $\dot{P}$ may have slowed in recent years, possibly indicating an irregular or cyclic rotational evolution.

Semiclassical approach to states near potential barrier top

description: Within the framework of the instanton approach we present analytical results for the following model problems: (i) particle penetration through a parabolic potential barrier, where the instanton solution practically coincides with the exact (quantum) one; (ii) descriptions of highly excited states in two types of anharmonic potentials: double-well $X^4$, and decay $X^3$. For the former case the instanton method reproduces accurately not only single well and double-well quantization but as well a crossover region (in the contrast with the standard WKB approach which fails to describe the crossover behavior), and for the latter case the instanton method allows to study resonance broadening and collapse phenomena. We investigate also resonance tunneling, playing a relevant role in many semiconducting devices. We show that in a broad region of energies the instanton approach gives exact (quantum) results. Applications of the method and of the results may concern the various systems in physics, chemistry and biology exhibiting double level behavior and resonance tunneling.

description: Based on angle resolved photoemission spectra measured on different systems at different dopings, momenta and photon energies, we show that the anomalously large spectral linewidth in the $(π,0)$ region of optimal doped and underdoped Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ has significant contributions from the bilayer splitting, and that the scattering rate in this region is considerably smaller than previously estimated. This new picture of the electronic excitation near $(π,0)$ puts additional experimental constraints on various microscopic theories and data analysis.

description: Starting from a one-dimensional model of relativistic fermions with $SO(5)$ spin and $U(N_f)$ flavor degrees of freedom we study the condensation of $SO(5)_{N_f}$ anyons. In the low-energy limit the quasi-particles in the spin sector of this model are found to be massive solitons forming multiplets in the $SO(5)$ vector or spinor representations. The solitons carry internal degrees of freedom which are identified as $SO(5)_{N_f}$ anyons. By controlling the external magnetic fields the transitions from a dilute gas of free anyons to various collective states of interacting ones are observed. We identify the generalized parafermionic cosets describing these collective states and propose a low temperature phase diagram for the anyonic modes.

description: In neutrino physics, it is now widely believed that neutrino oscillations are influenced by the presence of matter, modifying the energy spectrum produced by a neutrino beam traversing the Earth. Here, we will discuss the reverse problem, i.e. what could be learned about the Earth's interior from a single neutrino baseline energy spectrum, especially about the Earth's mantle. We will use a statistical analysis with a low-energy neutrino beam under very optimistic assumptions. At the end, we will note that it is hard to find petroleum with such a method, though it is not too far away from technical feasibility.
