description: In the braneworld scenario, the four dimensional effective Einstein equation has extra terms which arise from the embedding of the 3-brane in the bulk. These non-local effects, generated by the free gravitational field of the bulk, may provide an explanation for the dynamics of the neutral hydrogen clouds at large distances from the galactic center, which is usually explained by postulating the existence of the dark matter. We obtain the exact galactic metric, the dark radiation and the dark pressure in the flat rotation curves region in the brane world scenario. Due to the presence of the bulk effects, the flat rotation curves could extend several hundred kpc. The limiting radius for which bulk effects are important is estimated and compared with the numerical values of the truncation parameter of the dark matter halos, obtained from weak lensing observations. There is a relatively good agreement between the predictions of the model and observations. The deflection of photons is also considered and the bending angle of light is computed. The bending angle predicted by the brane world models is much larger than that predicted by standard general relativistic and dark matter models. The angular radii of the Einstein rings are obtained in the small angles approximation. The predictions of the brane world model for the tangential shear are compared with the observational data obtained in the weak lensing of galaxies in the Red-Sequence Cluster Survey. Therefore the study of the light deflection by galaxies and the gravitational lensing could discriminate between the different dynamical laws proposed to model the motion of particles at the galactic level and the standard dark matter models.

description: We analyse the evolution of close binary systems containing a neutron star that lead to the formation of redback pulsars. Recently there has been some debate on the origin of such systems and the formation mechanism of redbacks may still be considered as an open problem. We show that the operation of a strong evaporation mechanism, starting from the moment when the donor star becomes fully convective (or alternatively since the formation of the neutron star by accretion induced collapse), produces systems with donor masses and orbital periods in the range corresponding to redbacks with donors appreciably smaller than their Roche lobes, i.e., they have low filling factors (lower than $0.75$). Models of redback pulsars can be constructed assuming the occurrence of irradiation feedback. They have been shown to undergo cyclic mass transfer during the epoch at which they attain donor masses and orbital periods corresponding to redbacks, and stay in quasi-Roche lobe overflow conditions with {\it high} filling factors. We show that, if irradiation feedback occurs and radio ejection inhibits further accretion onto the neutron star after the first mass transfer cycle, the redback systems feature {\it high} filling factors. We suggest that the filling factor should be considered as a useful tool for discriminating among those redback formation mechanisms. We compare theoretical results with available observations, and conclude that observations tend to favour models with high filling factors.

description: We introduce a new family of distributions to approximate $\mathbb {P}(W\in A)$ for $A\subset\{...,-2,-1,0,1,2,...\}$ and $W$ a sum of independent integer-valued random variables $ξ_1$, $ξ_2$, $...,$ $ξ_n$ with finite second moments, where, with large probability, $W$ is not concentrated on a lattice of span greater than 1. The well-known Berry--Esseen theorem states that, for $Z$ a normal random variable with mean $\mathbb {E}(W)$ and variance $\operatorname {Var}(W)$, $\mathbb {P}(Z\in A)$ provides a good approximation to $\mathbb {P}(W\in A)$ for $A$ of the form $(-\infty,x]$. However, for more general $A$, such as the set of all even numbers, the normal approximation becomes unsatisfactory and it is desirable to have an appropriate discrete, nonnormal distribution which approximates $W$ in total variation, and a discrete version of the Berry--Esseen theorem to bound the error. In this paper, using the concept of zero biasing for discrete random variables (cf. Goldstein and Reinert [J. Theoret. Probab. 18 (2005) 237--260]), we introduce a new family of discrete distributions and provide a discrete version of the Berry--Esseen theorem showing how members of the family approximate the distribution of a sum $W$ of integer-valued variables in total variation.

description: We present a photometric study of the field lenticular galaxy NGC 4546 using Gemini/GMOS imaging in g'r'i'z'. We perform a 2D image decomposition of the surface brightness distribution of the galaxy using GALFIT, finding that four components adequately describe it. The subtraction of this model from our images and the construction of a colour map allow us to examine in great detail the asymmetric dust structures around the galactic centre. In addition, we perform a detailed analysis of the globular cluster (GC) system of NGC 4546. Using a Gaussian Mixture Model algorithm in the colour-colour plane we detected hints of multiple groups of GC candidates: the classic blue and red subpopulations, a group with intermediate colours that present a concentrated spatial distribution towards the galaxy, and an additional group towards the red end of the colour distribution. We estimate a total GC population for NGC 4546 of $390\pm60$ members and specific frequency $S_N=3.3\pm0.7$, which is relatively high compared to the typical value for galaxies of similar masses and environment. We suggest that the unusual GC population substructures were possibly formed during the interaction that led to the formation of the young ultra-compact dwarf (NGC 4546-UCD1) found in this system. Finally, we estimate the distance modulus of NGC 4546 by analyzing its luminosity function, resulting in $(m-M)=30.75\pm0.12$ mag (14.1 Mpc).

description: We consider the problem of finding approximate analytical solutions for nonlinear equations typical of physics applications. The emphasis is on the modification of the method of Padé approximants that are known to provide the best approximation for the class of rational functions, but do not provide sufficient accuracy or cannot be applied at all for those nonlinear problems, whose solutions exhibit behaviour characterized by irrational functions. In order to improve the accuracy, we suggest a method of self-similarly corrected Padé approximants, taking into account irrational functional behaviour. The idea of the method is in representing the sought solution as a product of two factors, one of which is given by a self-similar root approximant, responsible for irrational functional behaviour, and the other being a Padé approximant corresponding to a rational function. The efficiency of the method is illustrated by constructing very accurate solutions for nonlinear differential equations. A thorough investigation is given proving that the suggested method is more accurate than the method of standard Padé approximants.

description: A discretization of a continuum theory with constraints or conserved quantities is called mimetic if it mirrors the conserved laws or constraints of the continuum theory at the discrete level. Such discretizations have been found useful in continuum mechanics and in electromagnetism. We have recently introduced a new technique for discretizing constrained theories. The technique yields discretizations that are consistent, in the sense that the constraints and evolution equations can be solved simultaneously, but it cannot be considered mimetic since it achieves consistency by determining the Lagrange multipliers. In this paper we would like to show that when applied to general relativity linearized around a Minkowski background the technique yields a discretization that is mimetic in the traditional sense of the word. We show this using the traditional metric variables and also the Ashtekar new variables, but in the latter case we restrict ourselves to the Euclidean case. We also argue that there appear to exist conceptual difficulties to the construction of a mimetic formulation of the full Einstein equations, and suggest that the new discretization scheme can provide an alternative that is nevertheless close in spirit to the traditional mimetic formulations.

description: A regular bouncing universe is obtained in the context of a dilaton-gravity brane world scenario. The scale factor starts in a contracting inflationary phase both in the Einstein and in the string frame, it then undergoes a bounce (due to interaction with the bulk Weyl tensor), and subsequently enters into a decelerated expanding era. This graceful exit is obtained at low curvature and low coupling, and without violating the Null Energy Condition.

description: We obtain a lower bound for the normalised height of a non-torsion hypersurface $V$ of a C.M. abelian variety $A$ which is a refinement of a precedent result. This lower bound is optimal in terms of the geometric degree of $V$, up to an absolute power of a ``log'' (independant of the dimension of $A$). We thus extend the results of F. Amoroso and S. David on the same problem on a multiplicative group $\mathbb{G}_m^n$. When $A$ is an elliptic curve and $V=\bar{P}$ is the set of conjugates of a non torsion $\bar{k}$-point, we reobtain the result of M. Laurent on the elliptic Lehmer's problem.

description: Quantum computing, along with quantum metrology and quantum communication, are disruptive technologies that promise, in the near future, to impact different sectors of academic research and industry. Among the computational challenges with great interest in science and industry are the inversion problems. These kinds of numerical procedures can be described as the process of determining the cause of an event from measurements of its effects. In this paper, we apply a recursive quantum algorithm to a D-Wave quantum annealer to solve a small scale seismic inversions problem. We compare the obtained results from the quantum computer to those derived from a classical algorithm. The accuracy achieved by the quantum computer is at least as good as that of the classical computer.

Encrusting sponge, size 2–4 cm length × 1–3 cm width and 6–8 mm thick growing over rocks. Oscules and ostia are not visible. Surface hispid due to evenly distributed projecting spicules. Consistency fleshy and difficult to tear. Colour in life yellow or green, pale brown in preservation (Figure 14A).   Skeleton
 Straight choanosomal tylostyles: 1320–2400 × 10–25 µm (Figures 15A, B, 16A). Acanthostyles with short recurved spines in two sizes: 1) 130–180 × 5–7.5 µm (Figures 15C, 16C); 2) 55–87.5 × 2.5–5 µm (Figures 15D, 16C). Straight strongyloxeas / styles: 400–550 × 5–10 µm (Figures 15E, 16B) (Table 8). The ectosomal skeleton is absent. The points of the spicules are protruding externally. The choanosomal skeleton has a hymedesmoid structure. Main tylostyles and acanthostyles are embedded in a spongin layer (20–40 µm thick). The strongyloxeas and styles are dispersed in groups of one to three arranged along the tylostyles in the choanosome (Figure 16D).    Remarks
 Eurypon patriciae sp. nov. is a subtidal sponge distributed in the Gulf of California. In the Eastern Pacific, there are two species assigned to this genus. Eurypon nigrum Bergquist 1967 is a blue encrusting sponge described from Oahu (Hawaii). It has tylostyles in two sizes (1200–2400 µm × 6–12 µm and 170–800 × 6–12 µm) and acanthotylostyles (70–165 × 6–9 µm). The spicule measurements are similar in these two species. However, E. nigrum has tylostyles as ectosomal spicules while E. patriciae sp. nov. has strongyloxeas and styles. Eurypon miniaceum Thiele 1905 is a red encrusting sponge described from Calbuco (Chile) at 30 m depth. It has tylostyles in three categories (2000–3000 × 30 µm; 800 × 30 µm; and > 120 µm), acanthostyles (120 µm) and subectosomal styles (550 × 5 µm). Eurypon patriciae sp. nov. has one category of styles while E. miniaceum has three.    Etymology
Named for Patricia Bergquist for her contribution to sponge science.

description: Epistasis is a key concept in the theory of adaptation. Indicators of epistasis are of interest for large systems where systematic fitness measurements may not be possible. Some recent approaches depend on information theory. We show that considering shared entropy for pairs of loci can be misleading. The reason is that shared entropy does not imply epistasis for the pair. This observation holds true also in the absence of higher order epistasis. We discuss a method for reducing the number of false positives. However, our main conclusion is that entropy-based approaches have serious limitations in this context.

description: A (n+1)-dimensional cosmological model with a set of scalar fields and antisymmetric (p+2)-form is considered. Some of scalar fields may have negative kinetic terms, i.e. they may describe ``phantom'' fields. For certain odd dimensions (D = 4m+1 = 5, 9, 13, ...) and (p+2)-forms (p = 2m-1 = 1, 3, 5, ...) and non-exceptional dilatonic coupling vector $\vecλ$ we obtain cosmological-type solutions to the field equations. These solutions are characterized by self-dual or anti-self-dual charge density forms Q (of rank 2m) and may describe the maximal set of branes (i.e. when all the branes have non-zero charge densities). Some properties of these solutions are considered, e.g. Kasner-like behavior, the existence of non-singular (e.g. bouncing) solutions and those with acceleration. The solutions with bouncing and acceleration take place when at least there is one ``phantom'' field in the model.

Accretion of dust grains as a possible origin of metal-poor stars with low alpha/Fe ratios
Creators: name: Shigeyama, Toshikazu

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The origin of low alpha/Fe ratios in some metal-poor stars, so called low-alpha stars, is discussed. It is found that most of low-alpha stars in the Galaxy are on the main-sequence. This strongly suggests that these stars suffered from external pollution. It is also found that the abundance ratios Zn/Fe of low-alpha stars both in the Galaxy and in dwarf spheroidal galaxies are lower than the average value of Galactic halo stars whereas damped Ly alpha absorbers have higher ratios. This implies that some low-alpha stars accreted matter depleted from gas onto dust grains. To explain the features in these low-alpha stars, we have proposed that metal-poor stars harboring planetary systems are the origin of these low-alpha stars. Stars engulfing a small fraction of planetesimals enhance the surface content of Fe to exhibit low alpha/Fe ratios on their surfaces while they are on the main-sequence, because dwarfs have shallow surface convection zones where the engulfed matter is mixed. After the stars leave the main-sequence, the surface convection zones become deeper to reduce the enhancement of Fe. Eventually, when the stars ascend to the tip of the red giant branch, they engulf giant planets to become low-alpha stars again as observed in dwarf spheroidal galaxies. We predict that low-alpha stars with low Mn/Fe ratios harbor planetary systems.

description: U.S. agricultural trade has improved significantly since the mid-1980's. Exports jumped from $26 billion in 1986 to $40 billion in 1990, and import growth slowed as the world economy and U.S. competitiveness improved. Farm exports outpaced imports (table 1), more than tripling the U.S. agricultural trade surplus to nearly $18 billion—the seventh highest ever. Despite agriculture's trade gains over the last 5 years, the sector has not completely recovered to the record-high early- 1980's levels. In 1990, exports were higher than in the mid-1980's, but lagged earlier years. Export value remained 8- percent below the 1981 record. The volume of exports was also substantially below peak levels. Export volume totaled 148 million tons in 1990, compared with more than 160 million tons at the beginning of the 1980's. At the same time, imports hit their third consecutive record high in 1990, rising $1 billion to $22.5 billion. Imports of products that compete with domestic agriculture have continued to surge, offsetting the beneficial effects of declining prices for tropical imports which do not compete with domestic production, such as coffee.

Subjects: subject: Cryptography and Security (cs.CR)

description: Payment protocols developed to realize off-chain transactions in Payment channel network (PCN) assumes the underlying routing algorithm transfers the payment via a single path. However, a path may not have sufficient capacity to route a transaction. It is inevitable to split the payment across multiple paths. If we run independent instances of the protocol on each path, the execution may fail in some of the paths, leading to partial transfer of funds. A payer has to reattempt the entire process for the residual amount. We propose a secure and privacy-preserving payment protocol, CryptoMaze. Instead of independent paths, the funds are transferred from sender to receiver across several payment channels responsible for routing, in a breadth-first fashion. Payments are resolved faster at reduced setup cost, compared to existing state-of-the-art. Correlation among the partial payments is captured, guaranteeing atomicity. Further, two party ECDSA signature is used for establishing scriptless locks among parties involved in the payment. It reduces space overhead by leveraging on core Bitcoin scripts. We provide a formal model in the Universal Composability framework and state the privacy goals achieved by CryptoMaze. We compare the performance of our protocol with the existing single path based payment protocol, Multi-hop HTLC, applied iteratively on one path at a time on several instances. It is observed that CryptoMaze requires less communication overhead and low execution time, demonstrating efficiency and scalability.

A total of 107 cold tolerant rice accessions (99 landraces collected from 29 high hill and mountain districts, seven released varieties and newly introduced black rice) were characterized during 2015 and 2016 at National Agriculture Genetic Resources Centre (NAGRC), Khumaltar, Nepal. Accessions were shown a month later than normal planting time of Kathmandu valley to induce cold stress during flowering stage. The experiment was managed in direct seeded rainfed condition. Seven quantitative and nine qualitative traits were recorded using standard descriptors for rice and diversity among accessions was assessed. The accessions were found to be diverse using Shannon–Weaver diversity indices (H') for all the quantitative traits (0.822 to 0.882) whereas low to high diversity was observed for the qualitative traits (0.136 to 0.851). The accessions were grouped in five clusters where 65 accessions including all released varieties in Cluster-2 followed by 32 accessions in Cluster-5. Black rice with the earliest in maturity (104 days) and the shortest plant height (72 cm) formed a single cluster (Cluster-1) whereas C05459 with the latest in maturity (157 days) formed another single cluster (Cluster-4). Accessions in Cluster-5 were having earlier maturity (111 days) and longer panicles (24 cm), thus these accessions could be used for future breeding to develop cold tolerant varieties for rainfed areas.

Description
Encrusting sponge, size 3–6 cm length × 2–5 cm width and 2–10 mm thick. Oscules and ostia not observed. Surface hispid with spicule projections evenly distributed.
Consistency hard and difficult to tear. Colour in life is orange or yellow, pale in preservation (Figure 14C).   Skeleton
Straight choanosomal subtylostyles: 900–1710 × 10–30 µm (Figures 19A, B, 20A). Curved or straight acanthostyles with prominent recurved spines in two categories: 210–390 × 10–17.5 µm (Figures 19C, 20B) and 60–180 × 5–15 µm (Figures 19D, 20B) (Table 10). The ectosomal skeleton is absent. The points of the spicules protrude externally. The choanosomal skeleton has a hymedesmoid structure. Main subtylostyles and acanthostyles are erect in a spongin layer (10–20 µm thick) (Figure 20C).   Remarks
 Eurypon diversicolor sp. nov. is found in the Mexican Pacific Ocean. The only similar species in the Eastern Pacific is E. nigrum Bergquist 1967. This is a darkblue encrusting sponge described from Oahu (Hawaii). It has straight tylostyles in two sizes: 1200–2400 × 6–12 µm and 170–800 × 6–12 µm; and acanthostyles (70–165 × 6–9 µm). Eurypon diversicolor sp. nov. has acanthostyles in two categories (Table 10). The acanthostyles I are longer in E. diversicolor sp. nov. than in E. nigrum. Eurypon duoacanthostyla (Hoshino, 1981) is an orange encrusting sponge described from Mitsusuke (Japan) at 15 m depth. It has straight styles (250–320 × 5–8 µm) and acanthostyles in two categories: 250–280 × 7–9 µm and 138–180 × 6–8 µm. Eurypon diversicolor sp. nov. has longer and thicker styles than E. duoacanthostyla. The other species belonging to the genus Eurypon from the Pacific Ocean have spicules of different length than E. diversicolor sp. nov. (Table 12).    Etymology
 Named diversicolor which means different colours in Latin.

description: T. he U.S. Government has launched several new programs and expanded many older export programs to encourage foreign sales of U.S. commodities. But, several factors continue to limit U.S. agricultural exports. Protectionist trade policies of other nations, fluctuating exchange rates, and a depressed global economy continue to challenge global demand for U.S. agricultural products. Four broad categories of U.S. agricultural export programs—food aid, export credit guarantees, export payments, and nonprice promotion—assist both exporters and importers of U.S. agricultural commodities. Food aid programs help friendly nations overcome hunger (see "Overseas Food Aid," elsewhere in this issue). Export credit guarantees for U.S. agricultural goods make credit available to foreign buyers facing foreign exchange constraints. Export payments help exporters compete for sales of specific commodities in markets where competitors subsidize their exports. Nonprice export market promotions stimulate product awareness and acceptance in export markets

description: All the analyses of Cosmic Microwave Background (CMB) temperature maps up--to--date show that CMB anisotropies follow a Gaussian distribution. On the other hand, astrophysical foregrounds which hamper the detection of the CMB angular power spectrum, are not Gaussian distributed on the sky. Therefore, they should give a sizeable contribution to the CMB bispectrum. In fact, the first year data of the Wilkinson Microwave Anisotropy Probe (WMAP) mission have allowed the {\it first} detection of the extragalactic source contribution to the CMB bispectrum at 41 GHz and, at the same time, much tighter limits than before to non--Gaussian primordial fluctuations. In view of the above and for achieving higher precision in current and future CMB measurements of non--Gaussianity, in this paper we discuss a comprehensive assessment of the bispectrum due to either uncorrelated and clustered extragalactic point sources in the whole frequency interval around the CMB intensity peak. Our calculations, based on current cosmological evolution models for sources, show that the reduced angular bispectrum due to point sources, $b_{ps}$, should be detectable in all WMAP and Planck frequency channels. We also find agreement with the results on $b_{ps}$ at 41 GHz coming from the analysis of the first year WMAP data. Moreover, by comparing $b_{ps}$ with the primordial reduced CMB bispectrum, we find that only the peak value of the primordial bispectrum (which appears at $l\simeq 200$) results greater than $b_{ps}$ in a frequency window around the intensity peak of the CMB. The amplitude of this window basically depends on the capability of the source detection algorithms (i.e., on the achievable flux detection limit, $S_{lim}$, for sources).

Widening of the Andes: an interplay between subduction dynamics and crustal wedge tectonics

description: Shortening of the continental lithosphere is generally accommodated by the growth of crustal wedges building above megathrusts in the mantle lithosphere. We show that the locus of shortening in the western margin of South America has largely been controlled by the geometry of the slab. Numerical models confirm that horizontal subduction favors compression far from the trench, above the asthenospheric wedge and steeply dipping segment of the subducting slab. As a result, a second crustal wedge grows in the hinterland of the continent, and widens the Andes. In the Bolivian orocline, this wedge corresponds to the Eastern Cordillera, whose growth was triggered by a major episode of horizontal subduction. When the slab returned to a steeper dip angle, shortening and uplift pursued, facilitated by the structural and thermo-chemical alteration of the continental lithosphere. We review the successive episodes of horizontal subduction that have occurred beneath South America at different latitudes and show that they explain the diachronic widening of the Andes. We infer that the present-day segmented physiography of the Andes results from the latitudinally variable, transient interplay between slab dynamics and upper plate tectonics over the Cenozoic. We emphasize that slab flattening, or absence thereof, is a major driving mechanism that sets the width of the Andes, at any latitude.

description: The quantum vacuum effects are investigated for a massive scalar field with general curvature coupling and obeying the Robin boundary conditions given on two concentric spherical shells with radii $a $ and $b$ in the $D+1$-dimensional global monopole background. The expressions are derived for the Wightman function, the vacuum expectation values of the field square, the vacuum energy density, radial and azimuthal stress components in the region between the shells. A regularization procedure is carried out by making use of the generalized Abel-Plana formula for the series over zeros of combinations of the cylinder functions. This formula allows us to extract from the vacuum expectation values the parts due to a single sphere on background of the global monopole gravitational field, and to present the "interference" parts in terms of exponentially convergent integrals, useful, in particular, for numerical evaluations. The vacuum forces acting on the boundaries are presented as a sum of the self--action and interaction terms. The first one contains well known surface divergences and needs a further regularization. The interaction forces between the spheres are finite for all values $a

description: We argue that recently observed superconductivity-induced blue shift of the plasma frequency $δω_{pl}$ in $Bi_2Sr_2CaCu_2O_{8+δ}$ is related to the change in the integrated dynamical structure factor associated with the development of the spin resonance below $T_c$. We show that the magnitude of $δω_{pl}$ is consistent with the small integrated spectral weight of the resonance, and its temperature dependences closely follow that of the spin resonance peak.

description: We introduce the notion of a real form of a Hamiltonian dynamical system in analogy with the notion of real forms for simple Lie algebras. This is done by restricting the complexified initial dynamical system to the fixed point set of a given involution. The resulting subspace is isomorphic (but not symplectomorphic) to the initial phase space. Thus to each real Hamiltonian system we are able to associate another nonequivalent (real) ones. A crucial role in this construction is played by the assumed analyticity and the invariance of the Hamiltonian under the involution. We show that if the initial system is Liouville integrable, then its complexification and its real forms will be integrable again and this provides a method of finding new integrable systems starting from known ones. We demonstrate our construction by finding real forms of dynamics for the Toda chain and a family of Calogero--Moser models. For these models we also show that the involution of the complexified phase space induces a Cartan-like involution of their Lax representations.
