description: The chalcid wasp Dibrachys cavus (Walker) is a parasitoid of wax moths (Galleria mellonella). It would be interesting to find whether it could be used in the biological control of wax moths. For this purpose, we studied certain aspects of the biology of D. cavus attacking wax moths (Galleria mellonella) in vitro and its seasonal and relative abundance under field and laboratory conditions. The parasite attacks more the wax moth cocoons and less the mobile larvae, and it lays more eggs when it has more wax moth cocoons at its disposal. The survival rate of all the biological stages of D. cavus parasitized on Galleria was relatively high and ranged over 81.5%. The natural infestation of G. mellonella in months with high temperatures (June-August) was low (1.0–5.6%) and higher in the rest of the months (6.5–72%). The release of parasitoids for controlling infestation in the beekeeper’s warehouse is promising for the biological control of G. mellonella.

description: Infections caused by Lotmaria passim, Crithidia mellificae, Nosema spp. are frequently observed in bee colonies. The aim of this study was to determine the age at which honey bee worker larvae are most susceptible to the above parasites. Three apiaries (group C—central Poland, group E—north-eastern Poland, group S—southern Poland) with the highest number of colonies infected with Nosema spp. were chosen for the study. Six bee colonies were selected in each apiary, and bee workers of different developmental stages were sampled. The presence of parasites was determined by real-time PCR. The results were processed statistically by two-way analysis of variance (ANOVA) and the least significant difference post-hoc test. The relationship between the presence of the parasites and larval age within groups was analyzed statistically. Significant differences (p < 0.05) in the presence of L. passim were found between 10-day-old larvae vs. 4-, 8-, 12-, 16-, 21-day-old bee brood. Differences in the presence of the analyzed parasites in differently aged larvae were also determined between groups. The presence of N. apis in 10-day-old larvae differed significantly (p < 0.05) between groups C and E. The study revealed that apparently, healthy bee colonies can be a source of infection for other colonies and larvae. C. mellificae was not identified in any of the analyzed groups.

description: We synthesized an l–arginine complex, containing Cu(II) and isothiocyanate ions, with the formula [Cu(l–Arg)2(NCS)]·(NCS)·H2O (1) (l–Arg = l–arginine). Two cis-chelated l–arginine zwitterions form the basal plane, while the weakly N–bonded isothiocyanate (Cu1–N1 = 2.261 Å) is located at the apex of the distorted elongated square pyramidal structure, with τ = 0.143. The non-coordinated NCS- anions held layers together in a 3D supramolecular network. The crystal structure, spectroscopic (FT–IR, Raman, NIR–Vis–UV, EPR) and magnetic properties of 1 have been compared with [Cu(l–Arg)(NCS)2] (2). For 1, two absorptions are observed for ν(C = N) stretching vibrations, corresponding to NCS- ions N–bonded to the central Cu(II) (2077 cm−1) and in the lattice (2057 cm−1). In 2, however, a single band is observed at 2102 cm−1, indicating equivalent NCS- ions in the structure. The EPR spectra of both complexes show axial character and anisotropic signal with g⊥ and g|| 2.062, 2.235 (1) and 2.08, 2.225 (2) characteristic for cis-N2O2 and N3O donor sets in the xy plane, respectively. The unpaired electron mainly occupies the dx2-y2 orbital, also confirmed by the single envelope of d–d bands with maxima at ca. 16,000 cm−1 for 1 and 16,500 cm−1 for 2. The magnetic properties of both compounds are characteristic of a very weak antiferromagnetic interaction with the values of the coupling constant, J = –0.055 cm−1 and J = –0.096 cm−1 for 1 and 2, respectively.

description: Stingless bees are important pollinators in tropical and subtropical areas. The breeding of native stingless bee species from the Meliponini tribe to obtain honey, pollen, and geopropolis (meliponiculture) is a promising activity in Brazil with economic, social, and environmental impacts. Stingless bees can share food sources with Apis mellifera and other insects that can be vectors of pathogens. Here, we investigated seven stingless bee species from Brazil (Melipona quadrifasciata anthidioides, Melipona scutellaris, Nannotrigona testaceicornis, Partamona helleri, Scaptotrigona xanthotricha, Tetragonisca angustula, and Trigona spinipes) screening for seven of the most common pathogenic viruses (ABPV, IAPV, BQCV, CBPV, SBV, KBV, and DWV) in A. mellifera in summer and winter seasons. All seven stingless bee species studied were positive for ABPV and IAPV (only in M. quadrifasciata anthidioides and T. spinipes), while ABPV was found in samples from summer and winter, IAPV was only found in winter. This is the first study detecting viruses in seven native stingless bee species in Brazil and because of the novelty of this area in Brazil, it is necessary to monitor native stingless bee colonies to investigate the impact of those viruses at a colony and individual level to avoid losses and impact to the native bees.

The $η$'s were produced in $e^{+}e^{-}$ collisions with 10 GeV center-of-mass energy at the Cornell Electron Storage Ring (CESR). We find with 90% confidence the upper limit on the branching fraction $B(η\to e^{+}e^{-}) < 7.7\times 10^{-5}$. The application of conventional elementary particle theory to this decay predicts a branching fraction of about $10^{-9}$.

On the connection of radio and $γ$-ray emission in blazars

description: Blazars are a sub-category of radio-loud active galactic nuclei with relativistic jets pointing towards to the observer. They are well-known for their non-thermal variable emission, which practically extends over the whole electromagnetic spectrum. Despite the plethora of multi-wavelength observations, the issue about the origin of the $γ$-ray and radio emission in blazar jets remains unsettled. Here, we construct a parametric leptonic model for studying the connection between the $γ$-ray and radio emission in both steady-state and flaring states of blazars. Assuming that relativistic electrons are injected continuously at a fixed distance from the black hole, we numerically study the evolution of their population as it propagates to larger distances while losing energy due to expansion and radiative cooling. In this framework, $γ$-ray photons are naturally produced at small distances (e.g. $10^{-3}$ pc) when the electrons are still very energetic, whereas the radio emission is produced at larger distances (e.g. $1$ pc), after the electrons have cooled and the emitting region has become optically thin to synchrotron self-absorption due to expansion. We present preliminary results of our numerical investigation for the steady-state jet emission and the predicted time lags between $γ$-rays and radio during flares.

description: A new type of Langevin equation exhibiting a non trivial phase transition associated with the presence of multiplicative noise is introduced. The equation is derived as a mesoscopic representation of the microscopic annealed Ising model (AIM) proposed by Thorpe and Beeman, and reproduces perfectly its basic phenomenology. The AIM exhibits a non-trivial behavior as the temperature is increased, in particular it presents a disorder-to-order phase transition at low temperatures, and a order-to-disorder transition at higher temperatures. This behavior resembles that of some Langevin equations with multiplicative noise, which exhibit also two analogous phase transitions as the noise-amplitude is increased. By comparing the standard models for noise-induced transitions with our new Langevin equation we elucidate that the mechanisms controlling the disorder-to-order transitions in both of them are essentially different, even though for both of them the presence of multiplicative noise is a key ingredient.

description: We report on the study of binary collisions between quantum droplets formed by an attractive mixture of ultracold atoms. We distinguish two main outcomes of the collision, i.e. merging and separation, depending on the velocity of the colliding pair. The critical velocity $v_c$ that discriminates between the two cases displays a different dependence on the atom number $N$ for small and large droplets. By comparing our experimental results with numerical simulations, we show that the non-monotonic behavior of $v_c(N)$ is due to the crossover from a compressible to an incompressible regime, where the collisional dynamics is governed by different energy scales, i.e. the droplet binding energy and the surface tension. These results also provide the first evidence of the liquid-like nature of quantum droplets in the large $N$ limit, where their behavior closely resembles that of classical liquid droplets.

Al dar cuenta de los componentes del modelo corporativo agropecuario (MCA) en la región y de su difusión, es posible observar que el paradigma tecnológico en que se sustenta no ha dado respuesta a los problemas de inequidad, exclusión y pobreza típicos de la región; por el contrario, ha exacerbado nudos conflictivos en diferentes ámbitos de la vida social y de la naturaleza. Observamos el polo capitalista de la agricultura por concentrarse ahí uso y el abuso de los recursos tecnológicos en la explotación del suelo. Seguir el desempeño de las corporaciones agroalimentaria e industriales se justifica porque ha devenido en el esquema de organización productiva que, de acuerdo con los gobiernos de la región, más promete en términos de prosperidad; también porque es predominante, en el sentido de que es en función de éste que se fijan el valor y los precios que operan el mercado global de bienes agropecuarios.

description: The evaluation of the average number S_N(t) of distinct sites visited up to time t by N independent random walkers all starting from the same origin on an Euclidean lattice is addressed. We find that, for the nontrivial time regime and for large N, S_N(t) \approx \hat S_N(t) (1-Δ), where \hat S_N(t) is the volume of a hypersphere of radius (4Dt \ln N)^{1/2}, Δ={1/2}\sum_{n=1}^\infty \ln^{-n} N \sum_{m=0}^n s_m^{(n)} \ln^{m} \ln N, d is the dimension of the lattice, and the coefficients s_m^{(n)} depend on the dimension and time. The first three terms of these series are calculated explicitly and the resulting expressions are compared with other approximations and with simulation results for dimensions 1, 2, and 3. Some implications of these results on the geometry of the set of visited sites are discussed.

description: Rotation is ubiquitous in the Universe, and recent kinematic surveys have shown that early type galaxies and globular clusters are no exception. Yet the linear response of spheroidal rotating stellar systems has seldom been studied. This paper takes a step in this direction by considering the behaviour of spherically symmetric systems with differential rotation. Specifically, the stability of several sequences of Plummer spheres is investigated, in which the total angular momentum, as well as the degree and flavour of anisotropy in the velocity space are varied. To that end, the response matrix method is customised to spherical rotating equilibria. The shapes, pattern speeds and growth rates of the systems' unstable modes are computed. Detailed comparisons to appropriate N-body measurements are also presented. The marginal stability boundary is charted in the parameter space of velocity anisotropy and rotation rate. When rotation is introduced, two sequences of growing modes are identified corresponding to radially and tangentially-biased anisotropic spheres respectively. For radially anisotropic spheres, growing modes occur on two intersecting surfaces (in the parameter space of anisotropy and rotation), which correspond to fast and slow modes, depending on the net rotation rate. Generalised, approximate stability criteria are finally presented.

description: Bees are affected by several factors, including pathogens and pesticides, which may cause mortality and consequent population decline. Considering the ecological and economic importance of these pollinators, this study evaluated the occurrence of the microsporidia Nosema apis and Nosema ceranae, the viruses ABVP, DWV, BQCV, KBV, IAPV and CBPV and residues of the pesticides atrazine, chlorantraniliprole, deltamethrin, fipronil and glyphosate in workers from field colonies of Africanized honey bee Apis mellifera across one year. The presence of pesticide residues was also evaluated in honey and pollen samples. All tested viruses were found in the workers, with BQCV showing the highest copy number. BQCV levels were correlated with relative humidity. Nosema ceranae was the only microsporidian with higher intensities of infection during summer and autumn; seasons with high availability of food resources, which can act as dispersers of this pathogen. Small amounts of glyphosate and its metabolite were detected in the bees tested. These data show that honey bees are contaminated with pathogens and pesticides in the field and present correlative data for these threats.

description: Scalar fields non--minimally coupled to (2+1)-gravity, in the presence of cosmological constant term, are considered. Non-minimal couplings are described by the term $ζR Ψ^2$ in the Lagrangian. Within a class of static circularly symmetric space-times, it is shown that the only existing physically relevant solutions are the anti-de Sitter space-time for $ζ=0$, and the Martinez-Zanelli black hole for $ζ=1/8$. We obtain also two new solutions with non-trivial scalar field, for $ζ=1/6$ and $ζ=1/8$ respectively, nevertheless, the corresponding space-times can be reduced, via coordinate transformations, to the standard anti-de Sitter space.

description: Incoherent neutron scattering experiments are simulated for simple dynamic models: a glass (with a smooth distribution of harmonic vibrations) and a viscous liquid (described by schematic mode-coupling equations). In most situations multiple scattering has little influence upon spectral distributions, but it completely distorts the wavenumber-dependent amplitudes. This explains an anomaly observed in recent experiments.

description: Statistics of many particle energy levels of a finite two-dimensional system of interacting electrons is numerically studied. It is shown that the statistics of these levels undergoes a Poisson to Wigner crossover as the strength of the disorder is decreased. This transition occurs at a similar strength of disorder as the one-electron delocalization crossover in a finite 2d system and develops almost simultaneously at all energies. We interpret this crossover in terms of delocalization in the space of occupation numbers of strongly bound and compact electron-hole pairs (excitons).

description: Apis mellifera bees can be infected by a multitude of parasites and pathogens that may cause colony losses. Among these pathogens, viruses are one of the main threats to the bees’ health and well-being. This study aimed to determine the prevalence of 7 viruses in adult bees by real-time PCR in two descriptive cross-sectional studies; the first survey was carried out in 2011 during the rainy season and the second survey from March 2013 to February 2014 during the rainy (May to October) and dry seasons (November to April) in two regions of Costa Rica where most of the beekeeping activity is concentrated. Most viruses had a higher prevalence in 2013-2014 compared to 2011, however, CBPV went from 37% to 3% and KBV from 7% to 1%, both significantly (p-value < 0.05). DWV, BQCV, SBV, and ABPV had at least 10 times higher odds to be present in an apiary in 2013-2014 compared to 2011. IAPV showed identical prevalences in both time periods. Significant statistical differences in the virus prevalences were observed when seasons, regions, and years were compared.

description: A novel marine nitrifying and aerobic denitrifying bacterium, was isolated and identified from shrimp culture ponds. The heterotrophic nitrifying and aerobic denitrifying characteristics of this strain were confirmed and investigated when ammonium chloride, nitrite sodium, and nitrate sodium were used as the sole nitrogen source. Furthermore, the highly precise analytical method of gas chromatography-isotope ratio mass spectrometry (GC-IRMS) was employed to determine the nitrogenous gases and clarify the nitrogen removal pathway of the bacterium.

description: Interelectron interactions and correlations in quantum dots can lead to spontaneous symmetry breaking of the self-consistent mean field resulting in formation of Wigner molecules. With the use of spin-and-space unrestricted Hartree-Fock (sS-UHF) calculations, such symmetry breaking is discussed for field-free conditions, as well as under the influence of an external magnetic field. Using as paradigms impurity-doped (as well as the limiting case of clean) two-electron quantum dots (which are analogs to helium-like atoms), it is shown that the interplay between the interelectron repulsion and the electronic zero-point kinetic energy leads, for a broad range of impurity parameters, to formation of a singlet ground-state electron molecule, reminiscent of the molecular picture of doubly-excited helium. Comparative analysis of the conditional probability distributions for the sS-UHF and the exact solutions for the ground state of two interacting electrons in a clean parabolic quantum dot reveals that both of them describe formation of an electron molecule with similar characteristics. The self-consistent field associated with the triplet excited state of the two-electron quantum dot (clean as well as impurity-doped) exhibits symmetry breaking of the Jahn-Teller type, similar to that underlying formation of nonspherical open-shell nuclei and metal clusters. Furthermore, impurity and/or magnetic-field effects can be used to achieve controlled manipulation of the formation and pinning of the discrete orientations of the Wigner molecules. Impurity effects are futher illustrated for the case of a quantum dot with more than two electrons.

On the scaling behavior of the abelian sandpile model

description: The abelian sandpile model in two dimensions does not show the type of critical behavior familar from equilibrium systems. Rather, the properties of the stationary state follow from the condition that an avalanche started at a distance r from the system boundary has a probability proportional to 1/sqrt(r) to reach the boundary. As a consequence, the scaling behavior of the model can be obtained from evaluating dissipative avalanches alone, allowing not only to determine the values of all exponents, but showing also the breakdown of finite-size scaling.
description: 4 pages, 5 figures; the new version takes into account that the radius distribution of avalanches cannot become steeper than a certain power law
Large Orders for Self-Avoiding Membranes

description: We derive the large order behavior of the perturbative expansion for the continuous model of tethered self-avoiding membranes. It is controlled by a classical configuration for an effective potential in bulk space, which is the analog of the Lipatov instanton, solution of a highly non-local equation. The n-th order is shown to have factorial growth as (-cst)^n (n!)^(1-epsilon/D), where D is the `internal' dimension of the membrane and epsilon the engineering dimension of the coupling constant for self-avoidance. The instanton is calculated within a variational approximation, which is shown to become exact in the limit of large dimension d of bulk space. This is the starting point of a systematic 1/d expansion. As a consequence, the epsilon-expansion of self-avoiding membranes has a factorial growth, like the epsilon-expansion of polymers and standard critical phenomena, suggesting Borel summability. Consequences for the applicability of the 2-loop calculations are examined.

description: We present ten metallicity measurements for quasar absorbers near $z=1.2$ that were selected for having unusually significant ZnII absorption in their SDSS spectra. Follow-up UV space spectroscopy of the Ly$α$ region shows that all ten have damped Ly$α$ (DLA) absorption, corresponding to neutral hydrogen column densities in the range $2.4\times 10^{20}$ $\le$ N(HI) $\le$ $2.5\times 10^{21}$ atoms cm$^{-2}$, and indicating that the gas is very optically thick and essentially neutral. The sample is a very small subset of systems compiled by searching the University of Pittsburgh catalog of $\approx 30,000$ intervening MgII absorption line systems in SDSS quasar spectra up to DR7. We started by isolating $\approx 3,000$ that had strong MgII absorption in the redshift interval $1.0 < z < 1.5$ in brighter background quasars. Of these, 36 exhibited significant absorption near ZnII. Space UV spectroscopy was then obtained for nine of these (25% of the total), and a tenth system in a fainter quasar was found in the HST archives. The result is a representative sample of the highest Zn$^+$ columns of gas within the DLA population. These ZnII-selected systems define the upper envelope of DLA metallicities near $z=1.2$. They show a tight anti-correlation between N(HI) and [Zn/H], with the higher metallicity systems clearly exhibiting more depletion based on [Cr/Zn] values. The various metal-line measurements (Zn, Cr, Si, Fe, Mn) indicate evolved neutral gas with $-0.9 \le$ [Zn/H] $\le +0.4$.

description: An effective field theory for the three-body system with large scattering length is applied to three-body recombination to a weakly-bound s-wave state in a Bose gas. Our model independent analysis demonstrates that the three-body recombination constant alpha is not universal, but can take any value between zero and 67.9 \hbar a^4/m, where a is the scattering length. Other low-energy three-body observables can be predicted in terms of a and alpha. Near a Feshbach resonance, alpha should oscillate between those limits as the magnetic field B approaches the point where a -> infinity. In any interval of B over which a increases by a factor of 22.7, alpha should have a zero.

description: The Asian hornet (Vespa velutina) has rapidly become a source of stress for the beekeeping sector. Several methods have been developed to control its impact and spread, though some of these impose a high risk for native insects. Among these methods are electric harps, which are physical barriers that electrocute hornets pass through two wires powered by a current generator. Here we evaluated the selectiveness and risk of damage for local entomofauna of the electric harps in a study carried out over three years and four locations in Girona province (NE Catalonia, Spain). The electric harps showed a high selectiveness, with 90.5% of all insects trapped (3331 individuals) catalogued as Asian hornets, although this greatly varied over years and locations with values ranging from 29.9 to 94.3%. The risk of damage to electric harps for local entomofauna was very low in all surveyed areas and years. Native insects, excluding domestic honey bees, accounted for, as a mean, 1.2% of all insects trapped over the study period (range 0–2.4%). Our results suggest that electric harps might be a useful environmentally-friendly method aiming to reduce predation pressure of the Asian hornet at beehives.

description: Varroa destructor and the pathogens they vector have contributed significantly to high annual honey bee colony losses. Deformed wing virus (DWV) is the most prevalent honey bee virus and has been associated with overwintering colony loss. DWV is capable of infecting honey bees at all life stages and castes via horizontal and vertical transmission. Few studies have been conducted to determine the effect that pathogens have on honey bee queen health and performance. Our results suggest that queens may have mechanisms that reduce the establishment of DWV infection following a single exposure event. A queen’s exposure to DWV-A prior to colony establishment did not significantly negatively impact colony strength metrics for two of three queen genotypes tested. Additionally, brood showed little subsequent infection. These findings suggest that when queens experience a single oral or venereal inoculation of DWV-A, vertical transmission may not result in significant brood infection and that overall colony strength may be largely unaffected. Increased colony loss experienced by colonies derived from one queen source indicates that differences in susceptibility exist due to factors that need to be investigated more fully. These findings contribute to a greater understanding of host-pathogen interactions in honey bees and suggest a context-dependent variability on the influence of queen exposure to viruses on colony health.
