description: Topological quantum materials coupled with magnetism can provide a platform for realizing rich exotic physical phenomena, including quantum anomalous Hall effect, axion electrodynamics and Majorana fermions. However, these unusual effects typically require extreme experimental conditions such as ultralow temperature or sophisticate material growth and fabrication. Recently, new intrinsic magnetic topological insulators were proposed in MnBi2Te4-family compounds - on which rich topological effects could be realized under much relaxed experimental conditions. However, despite the exciting progresses, the detailed electronic structures observed in this family of compounds remain controversial up to date. Here, combining the use of synchrotron and laser light sources, we carried out comprehensive and high resolution angle-resolved photoemission spectroscopy studies on MnBi2Te4, and clearly identified its topological electronic structures including the characteristic gapless topological surface states. In addition, the temperature evolution of the energy bands clearly reveals their interplay with the magnetic phase transition by showing interesting differences for the bulk and surface states, respectively. The identification of the detailed electronic structures of MnBi2Te4 will not only help understand its exotic properties, but also pave the way for the design and realization of novel phenomena and applications.

description: We explore the dynamics of neutrinos in a vacuum dominated cosmology. First we show that such a geometry will induce a phase change in the eigenstates of a massive neutrino and we calculate the phase change. We also calculate the delay in the neutrino flight times in this geometry. Applying our results to the presently observed background vacuum energy density, we find that for neutrino sources further than $1.5 Gpc$ away both effects become non-trivial, being of the order of the standard relativistic corrections. Such sources are within the obsevable Hubble Deep Field. The results which are theoretically interesting are also potentially useful, in the future, as detection techniques improve. For example such effects on neutrinos from distant sources like supernovae could be used, in an independent method alternative to standard candles, to constrain the dark energy density and the deceleration parameter. The discussion is extended to investigate Caianiello's inertial or maximal acceleration (MA) effects of such a vacuum dominated spacetime on neutrino oscillations. Assuming that the MA phenomenon exists, we find that its form as generated by the presently observed vacuum energy density would still have little or no measurable effect on neutrino phase evolution.

description: In the Minimal Supersymmetric Standard Model (MSSM) we calculate the corrections to neutral CP-even Higgs-boson production in the WW-fusion and Higgs-strahlung channel, e+e- -> \bar nu nu {h,H}, at a future Linear Collider, taking into account all O(alpha) corrections arising from loops of fermions and sfermions. For the production of the lightest MSSM Higgs boson, h, we find genuine loop corrections (beyond the universal Higgs propagator corrections) of up to -5%. For the heavy CP-even neutral Higgs boson, H, which shows decoupling behavior at tree level, we find non-negligible corrections that can enhance the cross section considerably in parts of the MSSM parameter space. At a center-of-mass energy of \sqrt{s} = 1000 GeV, heavy CP-even Higgs-boson masses of up to M_H <= 700 GeV are accessible at the Linear Collider in favorable regions of the MSSM parameter space.

Evolution of circular, non-equatorial orbits of Kerr black holes due to gravitational-wave emission: II. Inspiral trajectories and gravitational waveforms

description: The inspiral of a ``small'' ($μ\sim 1-100 M_\odot$) compact body into a ``large'' ($M \sim 10^{5-7} M_\odot$) black hole is a key source of gravitational radiation for the space-based gravitational-wave observatory LISA. The waves from such inspirals will probe the extreme strong-field nature of the Kerr metric. In this paper, I investigate the properties of a restricted family of such inspirals (the inspiral of circular, inclined orbits) with an eye toward understanding observable properties of the gravitational waves that they generate. Using results previously presented to calculate the effects of radiation reaction, I assemble the inspiral trajectories (assuming that radiation reacts adiabatically, so that over short timescales the trajectory is approximately geodesic) and calculate the wave generated as the compact body spirals in. I do this analysis for several black hole spins, sampling a range that should be indicative of what spins we will encounter in nature. The spin has a very strong impact on the waveform. In particular, when the hole rotates very rapidly, tidal coupling between the inspiraling body and the event horizon has a very strong influence on the inspiral time scale, which in turn has a big impact on the gravitational wave phasing. The gravitational waves themselves are very usefully described as ``multi-voice chirps'': the wave is a sum of ``voices'', each corresponding to a different harmonic of the fundamental orbital frequencies. Each voice has a rather simple phase evolution. Searching for extreme mass ratio inspirals voice-by-voice may be more effective than searching for the summed waveform all at once.

Evidence in favor of Single Parton Scattering mechanism in $Υ$ and $D$ associated production at the LHC

description: Associated production of prompt $Υ(1S)$ and $D^{+,0}$ mesons has been proposed as a golden channel for the search of Double Parton Scattering, because Single Parton Scattering contribution to the cross-section is believed to be negligible on a basis of leading order calculations in the Collinear Parton Model. We study this process in the leading order approximation of the Parton Reggeization Approach. Hadronization of $b\bar{b}$-pair into bottomonium states is described within framework of the NRQCD-factorization approach while production of $D$ mesons is described in the fragmentation model with scale-dependent fragmentation functions. We have found good agreement with LHCb data for various normalized differential distributions, except for the case of spectra on azimuthal angle differences at the small $Δφ$ values. Crucially, the total cross-section in our Single Parton Scattering model accounts for more than one half of observed cross-section, thus dramatically shrinking the room for Double Parton Scattering mechanism.

description: According to recent astrophysical observations the large scale mean pressure of our present universe is negative suggesting a positive cosmological constant like term. This article addresses the question of whether non-perturbative effects of self-interacting quantum fields in curved space-times may yield a significant contribution. Focusing on the trace anomaly of quantum chromo-dynamics (QCD), a preliminary estimate of the expected order of magnitude yields a remarkable coincidence with the empirical data, indicating the potential relevance of this effect.

description: Recently it was argued that an inflationary potential yielding power spectra characterized by a scale-invariant tensorial spectral index and a weakly scale-dependent scalar spectral index might account for a generic large-scale structure formation in the multiverses scenario of eternal inflation. Here it is shown that this statement remains true if the tensorial index is allowed to slowly vary in a wide range of angular scales. In the cases analyzed in this paper, the scalar index also slightly depends on the scales. Therefore, the production of closely resembling each other universes seems to be a common feature of inflationary scenarios with weakly scale-dependent spectral indices. With power-law inflation as the extreme case, this is the class of scenarios which may give the best fit to near future CMB observations.

description: Global demand for food and farm commodities continues to grow, while land and other natural resources are becoming increasingly scarce. Sustainable intensification is often seen as a new paradigm for increasing agricultural productivity in a socially and environmentally responsible way. Sustainable intensification requires a broad portfolio of technologies, including improved seeds, fertilizers, and various natural resource management (NRM) practices. However, possible synergies between different types of technologies are not yet sufficiently understood. Here, we address this knowledge gap. Using representative data from small farms in Kenya and a propensity score matching approach, we analyze income effects of various technologies and technology combinations. When adopted alone, some innovations produce positive effects, while others do not. Effects of certain technology combinations are larger. The largest income gains occur when improved seeds are adopted together with organic manure and zero tillage practices. This points at important synergies between input-intensive and NRM technologies. Yet, the number of farmers that have adopted such promising technology combinations is relatively small, implying that synergies are not yet fully exploited. More impact studies that explicitly account for possible synergies can add to the knowledge that is needed for designing and promoting technology combinations suitable for particular contexts.

description: In the first part of this paper, the extension of the Lieb-Schultz-Mattis theorem to dimensions larger than one is discussed. A counter example to the original formulation of Lieb-Schultz-Mattis and Affleck is exhibited and a more precise statement is formulated. The degeneracy of the ground-state in symmetry breaking phases with long-range order is analyzed. The second and third parts of the paper concern resonating valence-bond (RVB) spin liquids. In these phases the relationship between various authors approaches: Laughlin-Oshikawa, Sutherland, Rokhsar and Kivelson, Read and Chakraborty and the Lieb-Schultz-Mattis-Affleck proposal is studied. The deep physical relation between the degeneracy property and the absence of stiffness is explained and illustrated numerically. A new conjecture is formed concerning the absolute absence of sensitivity of the spin liquid ground-states to any twist of the boundary conditions (thermodynamic limit). In the third part of the paper the relations between the quantum numbers of the degenerate multiplets of the spin liquid phases are obtained exactly. Their relationship with a topological property of the wave functions of the low lying levels of this spin liquid phase is emphasized. In spite of the degeneracy of the ground-state, we explain why these phases cannot exhibit spontaneous symmetry breaking.

description: Many models that include small extra space dimensions predict graviton states which are well separated in mass, and which can be detected as resonances in collider experiments. It has been shown that the ATLAS detector at the Large Hadron Collider can identify such narrow states up to a mass of 2080 GeV in the decay mode G->ee, using a conservative model. This work extends the study of the ee channel over the full accessible parameter space, and shows that the reach could extend as high as 3.5 TeV. It then discusses ways in which the expected universal coupling of the resonance can be confirmed using other decay modes. In particular, the mode G-> di-photons is shown to be measurable with good precision, which would provide powerful confirmation of the graviton hypothesis. The decays G-> mu mu, WW, ZZ and jet--jet are measurable over a more limited range of couplings and masses. Using information from mass and cross-section measurements, the underlying parameters can be extracted. In one test model, the size of the extra dimension can be determined to a precision in length of 7x10^-33 m.

description: We study elliptic-like geodesic motion on hyperplanes orthogonal to the cylindrical symmetry axes of the Godel spacetime by using an eccentricity-semi-latus rectum parametrization which is familiar from the Newtonian description of a two-body system. We compute several quantities which summarize the main features of the motion, namely the coordinate time and proper time periods of the radial motion, the frequency of the azimuthal motion, the full variation of the azimuthal angle over a period, etc. Exact as well as approximate (i.e., Taylor-expanded in the limit of small eccentricity) analytic expressions of all these quantities are obtained. Finally, we consider their application to the gyroscope precession frequency along these orbits, generalizing the existing results for the circular case.

Exploring the link between exchange market pressure and monetary Policy in Ethiopia

description: Entrusted with the responsibilities of maintaining exchange rate stability, the central bank Ethiopia, namely, the National Bank of Ethiopia (NBE) has paid more attention to the maintenance of exchange rate stability in the formulation and implementation of monetary policy during the past years. These considerations often prompted the NBE to intervene in the foreign exchange market so as to influence exchange rate developments. A recent study that estimated an index of the Exchange Market Pressure(EMP) for Ethiopia over the period November, 2001 to December, 2005, on the other hand, reveals that in majority of the cases (in 42 months out of 49 months considered) the Ethiopian foreign exchange market was characterized by depreciation pressures (Abebe, 2006). According to a monetary model of exchange market pressure, an increase in domestic credit (expansionary monetary policy) will increase the EMP by decreasing foreign reserves, or by causing a depreciation of the exchange rate, or some combination of the two (Kim, 1985). The objective of this study is, therefore, to examine empirically the existence of such link between EMP and monetary policy in Ethiopia using the Girton-Roper monetary model of exchange market pressure and VAR technique. The result of the single equation model reveals that measure of the stance of monetary policy, i.e domestic credit growth, has a significant and positive impact on EMP. The VAR test provides further evidence supporting the claim that domestic credit has a positive impact on exchange market pressure. The estimated impulse response function (IRF) as well indicates a positive response of EMP due to a shock in domestic credit, implying that an expansionary monetary policy increases EMP in line with the traditional theory.

description: Cardiotonic steroids (CTS) are steroidal drugs, processed from the seeds and dried leaves of the genus Digitalis as well as from the skin and parotid gland of amphibians. The most commonly known CTS are ouabain, digoxin, digoxigenin and bufalin. CTS can be used for safer medication of congestive heart failure and other related conditions due to promising pharmacological and medicinal properties. Ouabain isolated from plants is widely utilized in in vitro studies to specifically block the sodium potassium (Na+/K+-ATPase) pump. For checking, whether ouabain derivatives are robust inhibitors of Na+/K+-ATPase pump, molecular docking simulation was performed between ouabain and its derivatives using YASARA software. The docking energy falls within the range of 8.470 kcal/mol to 7.234 kcal/mol, in which digoxigenin was found to be the potential ligand with the best docking energy of 8.470 kcal/mol. Furthermore, pharmacophore modeling was applied to decipher the electronic features of CTS. Molecular dynamics simulation was also employed to determine the conformational properties of Na+/K+-ATPase-ouabain and Na+/K+-ATPase-digoxigenin complexes with the plausible structural integrity through conformational ensembles for 100 ns which promoted digoxigenin as the most promising CTS for treating conditions of congestive heart failure patients.

description: We investigated the influence of vacuum annealing on interface properties of silicon carbide (SiC) metal-oxide-semiconductor (MOS) structures. For as-oxidized and nitric oxide (NO)-annealed samples, the interface state density ($D_{\rm it}$) near the conduction band edge ($E_{\rm C}$) of SiC did not increase by subsequent vacuum annealing. For phosphoryl chloride (POCl$_3$)-annealed samples, in contrast, $D_{\rm it}$ at $E_{\rm C}-0.2$ eV increased from $1.3\times10^{10}$ to $2.2\times10^{12}$ cm$^{-2}$eV$^{-1}$ by the vacuum annealing, and the channel mobility of MOS field effect transistors (MOSFETs) decreased from 109 to 44 cm$^2$V$^{-1}$s$^{-1}$. Mechanism of the observed increase in $D_{\rm it}$ was discussed based on the results of secondary ion mass spectrometry measurement.

description: Technical discussions of the Laser Interferometer Gravitational Wave Observatory (LIGO) sensitivity often focus on its effective sensitivity to gravitational waves in a given band; nevertheless, the goal of the LIGO Project is to ``do science.'' Exploiting this new observational perspective to explore the Universe is a long-term goal, toward which LIGO's initial instrumentation is but a first step. Nevertheless, the first generation LIGO instrumentation is sensitive enough that even non-detection --- in the form of an upper limit --- is also informative. In this brief article I describe in quantitative terms some of the science we can hope to do with first and future generation LIGO instrumentation: it short, the ``science reach'' of the detector we are building and the ones we hope to build.

description: The main purpose of this study has been to measure the influence of socioeconomic, demographic and location characteristics on households’ willingness to pay for improvement of solid waste services. The data for the study was obtained from a random sample of 200 households in Jimma town. Descriptive analysis of the data reveals that while some households are not willing to pay, others are interested to contribute either in labour, in cash or both for improvements in solid waste management services in Jimma town. Estimation results of a multinomial logit model indicate that these choices are influenced by a certain combination of family size, education and age of the household, years of schooling of children or family member, wealth, life-style and location of the dwelling unit. The study concludes with some policy implications for improved solid waste management services in Jimma town.

Material examined: 10 males, 20 females and 15 nymphs (7 samples, EMEC, MONZ).
 Remarks: From the Kellogg Collection, we examined one female labelled and reported by Kellogg (1906: 317) as “ Nirmus separatus ” from “ Oceanodroma cryptoleneura ” (= Oceanodroma castro) and we have identified it as Philoceanus becki. None of the specimens (syntypes) mentioned by Kellogg (1903: 88) were located in the EMEC or in other collections holding Kellogg material; therefore, they are presumed lost. The two Galápagos hosts listed above are the only known hosts for Philoceanus becki (see Price et al. 2003: 212).

description: Introduction: Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a rare genetic cause of renal impairment resulting from mutations in the MUC1, UMOD, HNF1B, REN, and SEC61A1 genes. Neither the national or global prevalence of these diseases has been determined. We aimed to establish a database of patients with ADTKD in Ireland and report the clinical and genetic characteristics of these families. Methods: We identified patients via the Irish Kidney Gene Project and referral to the national renal genetics clinic in Beaumont Hospital who met the clinical criteria for ADTKD (chronic kidney disease, bland urinary sediment, and autosomal dominant inheritance). Eligible patients were then invited to undergo genetic testing by a variety of methods including panel-based testing, whole exome sequencing and, in five families who met the criteria for diagnosis of ADTKD but were negative for causal genetic mutations, we analyzed urinary cell smears for the presence of MUC1fs protein. Results: We studied 54 individuals from 16 families. We identified mutations in the MUC1 gene in three families, UMOD in five families, HNF1beta in two families, and the presence of abnormal MUC1 protein in urine smears in three families (one of which was previously known to carry the genetic mutation). We were unable to identify a mutation in 4 families (3 of whom also tested negative for urinary MUC1fs). Conclusions: There are 4443 people with ESRD in Ireland, 24 of whom are members of the cohort described herein. We observe that ADTKD represents at least 0.54% of Irish ESRD patients.

However, males of C. barthorum can be easily separated by the rounded anterior margin of the clavate field (fig. 11) and the ovoid cymbium-bulb complex, with a smoothly, medially bent, corkscrew-shaped embolus (figs. 87–89).
 MALE: Total length 1.08. Carapace 0.49 long, 0.37 wide; abdomen 0.59 long, 0.25 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow. Sternum longer than wide, with oval field of clavate setae reaching anterior margin, covering about 4 = 5 of sternum length and about K of sternum width, anterior margin with rounded edges, with bare median band (fig. 11). Cheliceral fang elongated, fangs extremely long, thin, bent, and crossed (fig. 11). Abdomen ovoid, epigastric scutum not protruding. Cymbiumbulb complex ovoid with a broadly based and corkscrew-shaped embolus (figs. 87–89).
FEMALE: Unknown.
DISTRIBUTION: This species is found only at the type locality, in western Queensland (map 2).

Exchange rate movements’ effect on Sri Lanka-China trade
Creators: name: Alhaiki, Ahmad
Publisher: name: American University of Bahrain

Subjects: classificationCode: 38
subject: Economics

description: Purpose – The purpose of this paper is to examine empirically the effects of exchange rate movements on trade performance with reference to the Sri Lanka-China trade relationship over the quarterly period from 1993 to 2007. Design/methodology/approach – This paper tests this condition for the trade between Sri Lanka and China in two steps. First, it investigates the exchange rate movements on Sri Lanka’s aggregate exports and imports between China using selected variables such as the real bilateral exchange rate change, the change in income and the exchange rate volatility. Second, this study constructs a panel regression model using Sri Lanka’s sectoral exports and imports between China and tests whether exchange rate movements have detrimental effects on sectoral trade. Findings – The main finding is that bilateral exchange rate changes and exchange rate volatility do play an active role on trade, while income growth changes have less influence in determining the total exports and imports between two countries. The analysis of data shows that changes in real bilateral exchange rate, income and exchange rate volatility are playing a major role in determining sectoral exports and imports between Sri Lanka and China. Therefore, the findings suggest that the movements of exchange rate between these two countries do have significant effects on total trade as well as sectoral trade between Sri Lanka and China.

description: An SIR model with the coinfection of the two infectious agents in a single host population is considered. The model includes the environmental carry capacity in each class of population. A special case of this model is analyzed and several threshold conditions are obtained which describes the establishment of disease in the population. We prove that for small carrying capacity $K$ there exist a globally stable disease free equilibrium point. Furthermore, we establish the continuity of the transition dynamics of the stable equilibrium point, i.e. we prove that (1) for small values of $K$ there exists a unique globally stable equilibrium point, and (b) it moves continuously as $K$ is growing (while its face type may change). This indicate that carrying capacity is the crucial parameter and increase in resources in terms of carrying capacity promotes the risk of infection.

Classical and Quantum Thermodynamics of horizons in spherically symmetric spacetimes

description: A general formalism for understanding the thermodynamics of horizons in spherically symmetric spacetimes is developed. The formalism reproduces known results in the case of black hole spacetimes. But its power lies in being able to handle more general situations like: (i) spacetimes which are not asymptotically flat (like the de Sitter spacetime) and (ii) spacetimes with multiple horizons having different temperatures (like the Schwarzschild-de Sitter spacetime) and provide a consistent interpretation for temperature, entropy and energy. I show that it is possible to write Einstein's equations for a spherically symmetric spacetime in the form $TdS-dE=PdV$ near {\it any} horizon of radius $a$ with $S=(1/4)(4πa^2), |E| = (a/2)$ and the temperature $T$ determined from the surface gravity at the horizon. The pressure $P$ is provided by the source of the Einstein's equations and $dV$ is the change in the volume when the horizon is displaced infinitesimally. The same results can be obtained by evaluating the quantum mechanical partition function {\it without using Einstein's equations or WKB approximation for the action}. Both the classical and quantum analysis provide a simple and consistent interpretation of entropy and energy for de Sitter spacetime as well as for $(1+2)$ dimensional gravity. For the Rindler spacetime the entropy per unit transverse area turns out to be $(1/4)$ while the energy is zero. The approach also shows that the de Sitter horizon -- like the Schwarzschild horizon -- is effectively one dimensional as far as the flow of information is concerned, while the Schwarzschild-de Sitter, Reissner-Nordstrom horizons are not. The implications for spacetimes with multiple horizons are discussed.
