description: We report on a search for the decay $B^0\toρ^0ρ^0$ and other charmless modes with a $π^+π^-π^+π^-$ final state, including $B^0\toρ^0π^+π^-$, non-resonant $B^0\to 4π^{\pm}$, $B^0\toρ^0f_0(980)$, $B^0\to f_0(980)f_0(980)$ and $B^0\to f_0(980)π^+π^-$. These results are obtained from a data sample containing 657 million $B \overline B$ pairs collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We set an upper limit on $\mathcal{B}(B^0\toρ^0ρ^0)$ of $1.0\times 10^{-6}$ at the 90% confidence level (C.L.). From our $B^0\toρ^0ρ^0$ measurement and an isospin analysis, we determine the Cabibbo-Kobayashi-Maskawa phase $ϕ_2$ to be $91.7 \pm 14.9$ degrees. We find excesses in $B^0\to ρ^0π^+π^-$ and non-resonant $B^0\to 4π^{\pm}$ with 1.3$σ$ and 2.5$σ$ significance, respectively. The corresponding branching fractions are less than $12.0 \times 10^{-6}$ and $19.3 \times 10^{-6}$ at the 90% C.L. In addition, we set 90% C.L. upper limits as follows: $\mathcal{B}(B^0\toρ^0f_0(980))< 0.3 \times 10^{-6}$, $\mathcal{B}(B^0\to f_0(980)f_0(980))< 0.1 \times 10^{-6}$, and $\mathcal{B}(B^0\to f_0(980)π^+π^-)< 3.8 \times 10^{-6}$.

description: Indications of aluminium monoxide in atmospheres of exoplanets are being reported. Studies using high-resolution spectroscopy should allow a strong detection but require high accuracy laboratory data. A \textsc{marvel} (measured active rotational-vibrational energy levels) analysis is performed for the available spectroscopic data on $^{27}$Al$^{16}$O: 22\,473 validated transitions are used to determine 6\,485 distinct energy levels. These empirical energy levels are used to provide an improved, spectroscopically accurate version of the ExoMol ATP line list for $^{27}$Al$^{16}$O; at the same time the accuracy of the line lists for the isotopically-substituted species $^{26}$Al$^{16}$O, $^{27}$Al$^{17}$O and $^{27}$Al$^{18}$O are improved by correcting levels in line with the corrections used for $^{27}$Al$^{16}$O. These line lists are available from the ExoMol database at http://www.exomol.com.

description: Buyer-driven governance systems and the related value chain entry and stay barriers are known to have led to smallholder farmers exiting the Kenyan fresh fruits and vegetables export value chain. This paper addresses two gaps in this literature. First, the paper addresses the question of how the fresh fruits and vegetable export smallholder farmers have managed to secure their stay in this value chain known for its high entry barriers. Second, the paper addresses the question of what happens to the smallholders known to have exited the value chain. To explore the two gaps, transaction costs theory was applied. The results show that smallholders entry and stay in the value chain was underpinned by relational contract enforcement mechanism of supply reliability. Second, smallholders were found to occasionally exit and re-enter the value chain, depending on the prevailing risks. In conclusion, the paper argues that contemporary African value chain scholarship should consider the analysis of relational contracts and their enforcement mechanism as well as the totality of smallholders’ farming, in order to understand the motives behind smallholder value chain entry and stay decisions.

description: We present a method to compute the Fermi function of the Hamiltonian for a system of independent fermions, based on an exact decomposition of the grand-canonical potential. This scheme does not rely on the localization of the orbitals and is insensitive to ill-conditioned Hamiltonians. It lends itself naturally to linear scaling, as soon as the sparsity of the system's density matrix is exploited. By using a combination of polynomial expansion and Newton-like iterative techniques, an arbitrarily large number of terms can be employed in the expansion, overcoming some of the difficulties encountered in previous papers. Moreover, this hybrid approach allows us to obtain a very favorable scaling of the computational cost with increasing inverse temperature, which makes the method competitive with other Fermi operator expansion techniques. After performing an in-depth theoretical analysis of computational cost and accuracy, we test our approach on the DFT Hamiltonian for the metallic phase of the LiAl alloy.

description: Squeezing of light's quantum noise requires temporal rearranging of photons. This again corresponds to creation of quantum correlations between individual photons. Squeezed light is a non-classical manifestation of light with great potential in high-precision quantum measurements, for example in the detection of gravitational waves. Equally promising applications have been proposed in quantum communication. However, after 20 years of intensive research doubts arose whether strong squeezing can ever be realized as required for eminent applications. Here we show experimentally that strong squeezing of light's quantum noise is possible. We reached a benchmark squeezing factor of 10 in power (10dB). Thorough analysis reveals that even higher squeezing factors will be feasible in our setup.

The method is specialized to a random telegraph signal of Mittag-Leffler type. Analytical predictions are compared to Monte Carlo simulations. Non-Poisson dichotomous noise is non-stationary and standard spectral methods fail to describe it properly as they assume stationarity.

description: We report a high frequency/high magnetic field electron spin resonance (HF-ESR) spectroscopy study in the sub-THz frequency domain of the two representatives of the family of magnetic topological insulators (MnBi$_{2}$Te$_{4}$)(Bi$_{2}$Te$_{3}$)$_{n}$ with $n = 0$ and 1. The HF-ESR measurements in the magnetically ordered state at a low temperature of $T = 4$ K combined with the calculations of the resonance modes showed that the spin dynamics in MnBi$_{\text{4}}$Te$_{\text{7}}$ is typical for an anisotropic easy-axis type ferromagnet (FM) whereas MnBi$_{\text{2}}$Te$_{\text{4}}$ demonstrates excitations of an anisotropic easy-axis type antiferromagnet (AFM). However, by applying the field stronger than a threshold value $\sim 6$ T we observed in MnBi$_{\text{2}}$Te$_{\text{4}}$ a crossover from the AFM resonance modes to the FM modes which properties are very similar to the ferromagnetic response of MnBi$_{\text{4}}$Te$_{\text{7}}$. We attribute this remarkably unusual effect unexpected for a canonical easy-axis AFM, which, additionally, can be accurately reproduced by numerical calculations of the excitation modes, to the closeness of the strength of the AFM exchange and magnetic anisotropy energies which appears to be a very specific feature of this compound. Our experimental data evidences that the spin dynamics of the magnetic building blocks of these compounds, the Mn-based septuple layers (SLs), is inherently ferromagnetic featuring persisting short-range FM correlations far above the magnetic ordering temperature as soon as the SLs get decoupled either by introducing a nonmagnetic quintuple interlayer, as in MnBi$_{\text{4}}$Te$_{\text{7}}$, or by applying a moderate magnetic field, as in MnBi$_{\text{2}}$Te$_{\text{4}}$, which may have an effect on the surface topological band structure of these compounds.

description: Given recent developments in our understanding of the Large Magellanic Cloud's (LMC) impact on the Milky Way's (MW) dark matter subhalo population, we compare the signatures of dark matter and baryonic physics on subhalos in MW systems with realistic LMC analogs. In particular, we study the effects of self-interacting dark matter (SIDM), warm dark matter (WDM), and the Galactic disk on the peak maximum circular velocity ($V_{\mathrm{peak}}$) function, radial distribution, and spatial distribution of MW and LMC-associated subhalos using cosmological dark matter-only zoom-in simulations of MW+LMC systems. For a fixed abundance of subhalos expected to host dwarf galaxies ($V_{\mathrm{peak}}\gtrsim 20\ \mathrm{km\ s}^{-1}$), SIDM and WDM can produce a similar mass-dependent suppression of the subhalo $V_{\mathrm{peak}}$ function, while disk disruption is mass independent. Subhalos in the inner regions of the MW are preferentially disrupted by both self-interactions and the disk, while suppression in WDM is radially independent. The relative abundance of LMC-associated subhalos is not strongly affected by disk disruption or WDM, but is significantly suppressed in SIDM due to self-interactions with the LMC at early times and with the MW during LMC infall at late times, erasing spatial anisotropy in the MW subhalo population. These results provide avenues to distinguish dark matter and baryonic physics by combining properties of the MW and LMC subhalo populations probed by upcoming observations of satellite galaxies and stellar streams.

description: The variational principle is used to build a model which describes open shell nuclei with ground state deformations. Hartree-Fock equations are solved by using single particle wave functions whose radial parts depend on the projection of the angular momentum on the quantization axis. Pairing effects are taken into account by solving Bardeen-Cooper-Schrieffer equations in each step of the minimisation procedure. The Gogny D1S finite-range interaction and an extension of it that includes tensor terms are consistently used in both parts of our calculations. The model is applied to study a set of isotopes with 34 protons and of isotones with 34 neutrons. Total energies, density distributions, their radii and single particle energies are analysed and the results of our calculations are compared with the available experimental data. We focused our attention on the effects of the deformation and of the tensor force on these observables. Our model describes open shell nuclei from a peculiar perspective and opens the possibility of future theoretical developments.

The Tail of Late-forming Dwarf Galaxies in $Λ$CDM

description: We use a robust analytical model together with a high-resolution hydrodynamical cosmological simulation to demonstrate that in a $Λ$ cold dark matter ($Λ$CDM) universe, a small fraction of dwarf galaxies inhabiting dark matter (DM) halos in the mass range $3\times 10^{9} \lesssim M_{200} / M_{\odot} \lesssim 10^{10}$ form unusually late ($z<3$) compared to the bulk population of galaxies. These galaxies originate from the interplay between the stochastic growth of DM halos and the existence of a time-dependent DM halo mass below which galaxies do not form. The formation epoch of the simulated late-forming galaxies traces remarkably well the time when their host DM halos first exceeded a nontrivial (but well-understood) time-dependent critical mass, thus making late-forming dwarfs attractive cosmological probes with constraining power over the past growth history of their host halos. The agreement between our model and the simulation results demonstrates that the population of simulated late-forming dwarfs is a robust cosmological outcome and largely independent of the specific galaxy formation model included in the simulations provided: (1) the universe underwent cosmic reionization before $z_{\rm re} \sim 8$; (2) star formation proceeds in gas that self-gravitates; and (3) galaxy formation is largely restricted to atomic-cooling halos before $z_{\rm re}$. The scarcity of massive late-forming dwarfs expected in $Λ$CDM implies that the great majority of bright, metal-poor, and actively star-forming dwarfs observed in our local universe--the most obvious candidates for these late-forming galaxies--cannot be undergoing their formation for the first time at the present day in a $Λ$CDM universe.

description: Axion-like particles (ALPs) are hypothetical bosons which may couple with photons. Since many ALPs can be emitted from hot and dense astrophysical plasma, nearby supernovae (SNe) are a possible probe into their properties including the ALP mass m_a and the coupling constant g_{ag} between ALPs and photons. I calculated ALP emission from a type Ia SN (SN Ia) model with the near-Chandrasekhar mass. It is found that the ALP luminosity from SNe Ia reaches ~10^43(g_{ag}/10^-10 GeV^-1)^2 erg s^-1 if m_a < 1 MeV. Heavy ALPs emitted from SNe are unstable and decay into photons. I predict the time delay and the flux of decay photons that reach Earth from a nearby SN Ia. It is found that the decay photons may provide a constraint on g_{ag} which is as stringent as an SN 1987A limit if an SN Ia is located 1 kpc away or closer and next-generation MeV gamma-ray satellites observe it ~1-10 years after the explosion.

Female aggressiveness, breeding density, and monogamy in willow ptarmigan
Creators: name: Hannon, Susan Jean
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis I investigate the influence of aggression by females in setting breeding density and maintaining monogamy in a population of willow ptarmigan (Lagopus lagopus). The aims of the study were: 1) to test the hypothesis that female willow ptarmigan determine their own breeding density by spacing behaviour, independently of male density; 2) to evaluate the effect of interactions between the sexes on final breeding density; and 3) to examine factors which may constrain willow ptarmigan populations to monogamy. Sex ratio of the population was altered in spring by continuous removal of most males and females from separate plots. The effect of removals on numbers of the same and the opposite sex was monitored. The following results were obtained and conclusions reached: 1) Females and males defend territories against individuals of the same sex, and this behaviour prevents some potential recruits from breeding. Physiologically mature yearling females and males settled in response to the removal of territorial birds of like sex. 2) Density of territorial males may not determine the number of females that breed. Females settled at high density, despite a reduction in the density of males, defended territories against each other within the enlarged territories of the remaining males, and mated polygynously. 3) Settlement patterns and subsequent territory sizes of males may affect density of both males and females. Females preferred territories of medium to large size, and males with smaller territories often remained unmated. Competition by yearling males for limited space on the breeding area may reduce territory size below that acceptable to females. Females may also alter settlement patterns of males by ignoring territorial boundaries of males and inciting interactions between neighboring cocks. 4) Unshared male vigilance is not essential to, but may improve, female reproductive success in years of high predation. Polygynous females had similar breeding success and survived as well as monogamous females, except in a year of high nest predation when they suffered higher nest loss. 5) The aggressive behaviour of females may prevent polygyny from occurring in unmanipulated populations, if a polygyny threshold exists. Females are able to defend territories which are similar in size to those of males and thus can prevent secondary females from settling. Results of this study indicate that aggressive behaviour of females in a monogamous species may be an important factor in regulating population density. Future studies should examine physiological and ecological factors influencing agonistic behaviour of females and should attempt to manipulate female aggressiveness to test whether changes in this behaviour can cause changes in population density.
Reduced models of unidirectional flows in compliant rectangular ducts at finite Reynolds number

description: Soft hydraulics, which addresses the interaction between an internal flow and a compliant conduit, is a central problem in microfluidics. We analyze Newtonian fluid flow in a rectangular duct with a soft top wall at steady state. The resulting fluid--structure interaction (FSI) is formulated for both vanishing and finite flow inertia. At the leading-order in the small aspect ratio, the lubrication approximation implies that the pressure only varies in the streamwise direction. Meanwhile, the compliant wall's slenderness makes the fluid--solid interface behave like a Winkler foundation, with the displacement fully determined by the local pressure. Coupling flow and deformation and averaging across the cross-section leads to a one-dimensional reduced model. In the case of vanishing flow inertia, an effective deformed channel height is defined rigorously to eliminate the spanwise dependence of the deformation. It is shown that a previously-used averaged height concept is an acceptable approximation. From the one-dimensional model, a friction factor and the corresponding Poiseuille number are derived. Unlike the rigid duct case, the Poiseuille number for a compliant duct is not constant but varies in the streamwise direction. Compliance can increase the Poiseuille number by a factor of up to four. The model for finite flow inertia is obtained by assuming a parabolic vertical variation of the streamwise velocity. To satisfy the displacement constraints along the edges of the channel, weak tension is introduced in the streamwise direction to regularize the Winkler-foundation-like model. Matched asymptotic solutions of the regularized model are derived.

We analyse the high energy emission of the INTEGRAL source using all available data and provide complementary optical photometric and spectroscopic data obtained respectively in August and October 2006. Based on a refined INTEGRAL position, we confirm the proposed optical identification. We clearly detect the presence of a 564 s periodic optical modulation that we identify as the rotation of the white dwarf. The analysis of the optical spectrum also demonstrates that the emission lines show a modulation in radial velocity with an orbital period of Porb = (4.033 +/- 0.005) hr. The two periodicities indicate that IGR00234+6141 is a magnetic CV of the intermediate polar type. This is one of the faintest and hardest sources of this type detected by INTEGRAL. This confirms earlier conclusions that IPs contribute significantly to the population of galactic X-ray sources and represent a significant fraction of the high energy background.

description: We present optical and near-infrared photometry of the afterglow of the long Gamma-Ray Burst GRB 070802 at redshift 2.45 obtained with the ESO/MPI 2.2 m telescope equipped with the multi-channel imager GROND. Follow-up observations in g'r'i'z' and JHK_S bands started ~17 min and extended up to 28 h post burst. We find an increase in brightness of the afterglow at early times, which can be explained by the superposition of reverse and forward shock (FS) emission or the onset of the afterglow FS. Additionally, we detect a strong broad-band absorption feature in the i' band, which we interpret as extinction from the redshifted 2175 A bump in the GRB host galaxy. This is one of the first and clearest detections of the 2175 A feature at high redshift. It is strong evidence for a carbon rich environment, indicating that Milky Way or Large Magellanic Cloud like dust was already formed in substantial amounts in a galaxy at z=2.45.

description: Blazars are Active Galactic Nuclei characterized by relativistic jets launched in the vicinity of the central engine (i.e. a supermassive black hole), that are oriented close to our line of sight. Their peculiar orientation makes them very efficient tracers of the overall jetted population, and due to their brightness they can be visible up to very high redshifts. A deep knowledge of these objects can provide fundamental clues to the models of formation and growth of the first supermassive black holes, but their search in the early Universe must be careful and follow a systematic approach. The discovery in the last $\sim15$ years of extremely massive blazars at very high redshifts ($M_{\rm BH}>10^9M_\odot, \, z>4$) revolutionized our perception of their earliest evolution: there seem to be different formation epochs for extremely massive black holes hosted in jetted ($z\sim4$) and non-jetted systems ($z\sim2.5$). This is not easy to explain, since one would expect that jetted sources accrete less efficiently. Small differences in the population are also derived from the search of such high-$z$ sources: we will go through the open questions in order to understand where the common knowledge stands and which steps must be undertaken to better understand the formation and common evolution of supermassive black holes and jets in the early Universe.

description: The differential performance of rainbow trout (Salmo gairdneri) in small scale models of circular cross-section raceways, circular tanks, and vertical tanks were documented. The experimental tanks had a water volume of 47 liters each. A constant head reservoir supplied water to the culture tanks equally at a flow rate of 5 l/min. The fish with initial weight of 9.08 g (9.11 cm) were reared through 4 periods of 42 days each (August 14, 1981 January 31, 1982). For every period, the tanks were stocked with the same number of fish. All fish lots were fed equal daily ration at the same feeding frequency. The feed ration ranged from 3.0% to 0.8% body weight per day. The water temperature fluctuated from 17°C to 4°C. Water pH was consistently on the acid side with a low level of 5.1. Total ammonia levels were negligible with a high of 0.73 mg/l. The heaviest stocking density attained was 171.68 kg/m3. The calculated pond loading indices, Wi, ranged from 0.63 to 1.45 kg/l-cm while the carrying capacities ranged from 0.35 to 1.61 kg/l/min. The average weight of the heaviest fish lot at the end of the study was 101.80 g (19.94 cm). The tanks and growing periods were compared on the basis of percent weight gain, length gain, condition factor, and feed conversion ratio. The two-way analysis of variance showed significant variation from tank to tank and from growing period to growing period in everyone of these growth parameters. For all 4 periods, the percent weight gains and length gains in the vertical tanks were consistently the highest. The raceways gave the least gains. Feed conversion efficiencies were highest in the vertical tanks and least in the raceways. Feed conversion ratios varied from 1.23 to 2.93 kg of feeds/kg of fish. For a given length, the fish in the vertical and circular tanks were heavier than those in the raceways. The observed condition factors ranged from 0.0123 to 0.0133 g/cm³. The results of tracer experimentation confirmed that the circular tanks approximated an ideal mixed flow and that the raceways approximated an ideal plug flow. The vertical tanks exhibited hydraulic properties similar to those of the circular tanks indicating mixed flow conditions in the tanks. Correlation between growth rates and hydraulic characteristics indicated that growth rates are higher in mixed flow tanks than in plug flow tanks. The hydraulic studies also showed that fish biomass and activity significantly affected the hydraulic characteristics of the culture tanks.

description: In this paper, we propose a geometric integrator for nonholonomic mechanical systems. It can be applied to discrete Lagrangian systems specified through a discrete Lagrangian defined on QxQ, where Q is the configuration manifold, and a (generally nonintegrable) distribution in TQ. In the proposed method, a discretization of the constraints is not required. We show that the method preserves the discrete nonholonomic momentum map, and also that the nonholonomic constraints are preserved in average. We study in particular the case where Q has a Lie group structure and the discrete Lagrangian and/or nonholonomic constraints have various invariance properties, and show that the method is also energy-preserving in some important cases.

description: The low-energy magnetic excitations of the noncentrosymmetric heavy-fermion superconductor CePt3Si have been measured with inelastic neutron scattering on a single crystal. Kondo-type spin fluctuations with an anisotropic wave vector dependence are observed in the paramagnetic state. These fluctuations do not survive in the antiferromagnetically ordered state below TN=2.2 K but are replaced by damped spin waves, whose dispersion is much stronger along the c-axis than in other directions. No change is observed in the excitation spectrum or the magnetic order as the system enters the superconducting state below Tc=0.7 K.

description: Gravity is perturbatively renormalizable for the physical states which can be conveniently defined via foliation-based quantization. In recent sequels, one-loop analysis was explicitly carried out for Einstein-scalar and Einstein-Maxwell systems. Various germane issues and all-loop renormalizability have been addressed. In the present work we make further progress by carrying out several additional tasks. Firstly, we present an alternative 4D covariant derivation of the physical state condition by examining gauge choice-independence of a scattering amplitude. To this end, a careful dichotomy between the ordinary, and large gauge symmetries is required and appropriate gauge-fixing of the ordinary symmetry must be performed. Secondly, vacuum energy is analyzed in a finite-temperature setup. A variant optimal perturbation theory is implemented to two-loop. The renormalized mass determined by the optimal perturbation theory turns out to be on the order of the temperature, allowing one to avoid the cosmological constant problem. The third task that we take up is examination of the possibility of asymptotic freedom in finite-temperature quantum electrodynamics. In spite of the debates in the literature, the idea remains reasonable.

description: We probe non-equilibrium properties of an active bacterial bath through measurements of correlations of passive tracer particles and the response function of a driven, optically trapped tracer. These measurements demonstrate violation of the fluctuation-dissipation theorem and enable us to extract the power spectrum of the active stress fluctuations. In some cases, we observe $1/\sqrtω$ scaling in the noise spectrum which we show can be derived from a theoretical model incorporating coupled stress, orientation, and concentration fluctuations of the bacteria.

Bio-entity recognition for SABIO-RK database

description: SABIO-RK (http://sabiork.h-its.org) has been developed as an absolutely expert-curated database for biochemical reactions and their kinetic properties with the aim of supporting the computational modeling to create models of biochemical reaction networks and also allowing the experimentalists to acquire further knowledge about enzymatic activities and reaction properties. This work is an initial attempt to use text-mining tools in order to facilitate annotators of the database. The most fundamental task in biomedical text mining is the recognition of named entities (called NER) or simply bio-entities, such as proteins, species, diseases, chemicals or mutations. Current state-of-the-art NER methods rely on pre-defined features that try to capture the specific surface properties of entity types, properties of the typical local context, background knowledge, and linguistic information, which is a data- and computation-intensive process. In this work we explore and compare two modes of bio-entity recognition, namely entity-agnostic and entity-specific methods of bio-entity recognition. Entity-specific method is a fully-supervised method that entirely depends on SABIO-RK entity-definitions, whereas the entity-agnostic method can use other bio-chemical databases in addition to the SABIO-RK. This uses more feature engineering than the entity-specific method. We used state-of-the-art LSTM-CRF approach for these two methods. The overall accuracy of entity-specific method is significantly better than the entity-agnostic method. We also found that the precision is lower in entity-agnostic method whereas the recall is lower in entity-specific method. In future we may use a hybrid method of these two methods to use more data-sources in order to enrich our system.

description: Nontrivial strong dynamics often leads to the appearance of chiral composites. In phenomenological applications, these can either play the role of Standard Model particles or lift chiral exotics by partnering with them in mass terms. As a consequence, the RG flow may change the effective number of chiral generations, a phenomenon we call generation flow. We provide explicit constructions of globally consistent string models exhibiting generation flow. Since such constructions were misclassified in the traditional model searches, our results imply that more care than usually appreciated has to be taken when scanning string compactifications for realistic models.
