description: In this work an efficient algorithm to perform a block decomposition (and so to compute the rank) of large dense rectangular matrices with entries in $\mathbb{F}_2$ is presented. Depending on the way the matrix is stored, the operations acting on rows or block of consecutive columns (stored as one integer) should be preferred. In this paper, an algorithm that completely avoids the column permutations is given. In particular, a block decomposition is presented and its running times are compared with the ones adopted into SAGE.

description: We study the mean-field dynamics of p-wave Feshbach molecule production in an ultra cold gas of Fermi atoms in the same internal state. We derive a separable potential to describe the low-energy scattering properties of such atoms, and use this potential to solve the mean-field dynamics during a magnetic field sweep. Initially, on the negative scattering length side of a Feshbach resonance the gas is described by the BCS theory. We adapt the method by Szymańska et al. [Phys. Rev. Lett. 94, 170402 (2005)] to p-wave interacting Fermi gases and model the conversion dynamics of the gas into a Bose-Einstein condensate of molecules on the other side of the resonance under the influence of a linearly varying magnetic field. We have analyzed the dependence of the molecule production efficiency on the density of the gas, temperature, initial value of the magnetic field, and magnetic field ramp speed. Our results show that in this approximation molecule production by a linear magnetic field sweep is highly dependent on the initial state.

description: Recently, a New HDE model with action principle was proposed (Li and Miao, arXiv:1210.0966). This model completely solves the causality and circular problems in the original HDE model, and is similar to the original model except a new term that can be interpreted as dark radiation. In this paper, we make further investigations on this model from the aspect of cosmological observations. Numerically, we confirm that the equations of motion force the $L(z=-1)=0$, making the cut-off $aL$ exactly the future event horizon. We also perform detailed analysis on the dynamical properties of the model, divided into the $c<6$ and $c\geq6$ cases ($c$ is a dimensionless parameter which should be decided by the data). From a combination of the present Union2.1+BAO+CMB+$H_0$ data, we find the model yields $χ^2_{\rm min}=548.798$ (in a non-flat Universe), comparable to the results of the original HDE model (549.461) and the concordant $Λ$CDM model (550.354). At 95.4% CL, we get $1.41

description: Mimicking the maximum likelihood estimator, we construct first order Cramer-Rao efficient and explicitly computable estimators for the scale parameter $σ^2$ in the model $Z_{i,n}=σn^{-β}X_i+Y_i,i=1,\ldots,n,β>0$ with independent, stationary Gaussian processes $(X_i)_{i\in\mathbb{N}}$, $(Y_i)_{i\in\mathbb{N}}$, and $(X_i)_{i\in\mathbb{N}}$ exhibits possibly long-range dependence. In a second part, closed-form expressions for the asymptotic behavior of the corresponding Fisher information are derived. Our main finding is that depending on the behavior of the spectral densities at zero, the Fisher information has asymptotically two different scaling regimes, which are separated by a sharp phase transition. The most prominent example included in our analysis is the Fisher information for the scaling factor of a high-frequency sample of fractional Brownian motion under additive noise.

description: A dilute system of reacting particles transported by fluid flows is considered. The particles react as $A + A \to \varnothing$ with a given rate when they are within a finite radius of interaction. The system is described in terms of the joint n-point number spatial density that it is shown to obey a hierarchy of transport equations. An analytic solution is obtained in either the dilute or the long-time limit by using a Lagrangian approach where statistical averages are performed along non- reacting trajectories. In this limit, it is shown that the moments of the number of particles have an exponential decay rather than the algebraic prediction of standard mean-field approaches. The effective reaction rate is then related to Lagrangian pair statistics by a large-deviation principle. A phenomenological model is introduced to study the qualitative behavior of the effective rate as a function of the interaction length, the degree of chaoticity of the dynamics and the compressibility of the carrier flow. Exact computations, obtained via a Feynman-Kac approach, in a smooth, compressible, random delta-correlated-in-time Gaussian velocity field support the proposed heuristic approach.

description: We study the photon blockade phenomenon in a nanocavity containing a single four-level quantum emitter. By numerically simulating the second-order autocorrelation function of the intra-cavity field with realistic parameters achievable in a state-of-the-art photonic-crystal nanocavity, we show that in the strongly coupled regime the resulting photon blockade is significantly better than that achievable with a two-level emitter. We introduce an intuitive picture of the photon blockade with a four-level emitter that explains the performance difference between the two-level and the four-level emitter schemes, as well as why -- in contrast to a cavity containing a two-level atom -- signatures of photon blockade appear and should be experimentally observable even outside the strong coupling regime when a four-level emitter is used. Finally, we show that the emitter-cavity coupling achievable in a nanocavity can overcome the non-ideal spacing of optical transitions in realistic four-level emitters that has so far prevented experimental realization of this photon blockade scheme.

subject: FOS: Biological sciences

description: The koala (Phascolarctos cinereus) is a marsupial arboreal folivore, able to survive on a diet of eucalypt leaves by having low energy requirements for maintenance, activity and growth. This thesis examined the social organization of koalas, and the constraints imposed on this social organization by their phylogeny and by their dietary and energetic strategies as arboreal folivores.
A population of koalas at Redhill Creek, French Island, Victoria, was studied between November 1982 and November 1985. All trees on the study site were marked and mapped, and all koalas on the site were ear-tagged, and their sex and age recorded. The locations of koalas during systematic searches of the site were recorded, with descriptions of behaviour. Manipulations were carried out to test hypotheses related to dominance among male koalas.
Koalas were removed from the study site in the late 1970's . The population structure during the study reflected the repopulation of the site, beginning with the immigration of animals, mainly young males, which resulted in an initial sex ratio 31:23 and a density of 8.9 animals/ha before the removal of some animals in March 1984. The numbers and age of females increased as a result of their philopatry and longevity. Rates of immigration were highest for 2 to 3 year old males, but most immigrants did not remain on the site, particularly when the population density was high. Rates of death or emigration were also greatest males of 2 to 3 years. Older males were philopatric, and the male population increased in age during the study.
Systematic sampling of koala sightings showed that koalas spent 84 . 9% of their time resting, 11.7% feeding, 2.7% moving and 0 . 6% in interactions with other koalas. Koalas remained in the same tree for long periods; animals were in the same tree for 12.1% of sightings made 24h apart. Koalas were more active at night, and during breeding seasons.[...]

description: In their Letter [Phys. Rev. Lett. 105, 137402 (2010)], Eisfeld et al. predicted the exchange broadening and blue-shift of the absorption band as well as a nonuniversal disorder scaling of the localization length of excitons in J-aggregates with Levy disorder, which they contrasted with the previously analyzed Gaussian and Lorentzian case [Phys. Rev. B, 79, 1 (2009)]. The observations were explained by chain segmentation due to outliers, and its interplay with localization of states in effective potential wells created by typical random site energies. We argue that the previously known theory does not break down and thus anticipates the properties of absorption band investigated in the commented work.

description: Five sympatric species of Myrmecia were studied within a small isolated mallee area near Bacchus Marsh Victoria. The general biology of each species was investigated and an attempt made to determine any ecological differences by which direct interspecific competition was avoided. The social organization of each species was also examined using colonies maintained in the laboratory.
The external nest structure of each species was distinctive whereas the internal nest structure was similar in all species except in M. nigriscapa which was more complex. Migration of nests to new sites occurred in two species, M· forceps and M· nigriscapa.
Foraging was primarily nocturnal in four of the species and one of these, M· pyriformis, appeared entirely nocturnal. The remaining species, M. nigriscapa, had a highly variable foraging pattern, foraging whenever the temperature was favourable. Variation in the number of ants foraging at different times of the year was measured in each of the species; this correlated closely with the brood in the nest. M· pyriformis which carried a large number of larvae over winter, foraged more than the other species in this season. M· nigriscapa, had no brood in winter and ceased all activity. This absence of a winter brood was due to the restriction of the oviposition period in M· nigriscapa to the period around spring from mid-July to early December. Oviposition occurred throughout the year in the other species.[...]

We solve this system exactly in the 't Hooft limit, N,k\to\infty with λ= N/k fixed. The solution exists up to |λ|=1 for a fixed value of chemical potential. We study the system beyond |λ|=1 by considering U(N) gauge group and taking the diagonal U(1) holonomy into account. The result suggests the system becomes unstable and a phase transition happens at |λ|=1.

description: The D=10 pure spinor constraint can be solved in terms of spinor moving frame variables and 8-component complex null vector which can be related to the kappa-symmetry ghost. Using this and similar solutions for the conjugate pure spinor and other elements of the non-minimal pure spinor formalism we present a (hopefully useful) reformulation of the measure of the pure spinor path integral for superstring in terms of products of Cartan form corresponding to the coset of 10D Lorentz group and to the coset of complex orthogonal group SO(8,C). Our study suggests a possible complete reformulation of the pure spinor superstring in terms of new irreducible set of variable.

description: Report Summary: Exposing harvested asparagus spears to controlled atmospheres containing 20 percent carbon dioxide (C02 ) for 24 hours effectively reduced the incidence of bacterial soft rot at the butt end during subsequent holding of the spears in air (normal atmosphere) for about 1 week at 36°, 41°, or 50° F. An initially high (20 percent) but gradually decreasing concentration of C02 reduced soft rot at the butt end of spears in a simulated air transit test of 4 days at 59°. Neither treatment, however, was effective in reducing soft rot at the tips. Bacterial soft rot at the tips of spears was significantly lower in less mature tight tips than in more mature loose or feathered tips. Culling spears with loose tips before shipment would reduce market losses in this crop.

The ecology and reproductive biology of the European goldfinch, Carduelis carduelis near Melbourne, Victoria

description: Between December, 1962, and August, 1965, the ecology and reproductive biology of the European Goldfinch Carduelis carduelis was studied in the vicinity of Melbourne, Victoria, in an attempt to assess the role of this exotic species in the Australian environment.Throughput the year, field observations were made on all aspects of the goldfinch’s annual cycle. During the non-breeding season (January to late August) the goldfinch occupies an open habitat where large feeding flocks are common at all times of day. In early September the winter flocks break up, and the birds gradually return to the nesting areas. After a nest site has been selected by the female, small territories are established by the pair. Nests, situated almost exclusively in exotic shrubbery, are built between late September and late January. Clutch size at Melbourne is 4.8. The incubation and nestling periods average 13 and 15 days respectively. Egg hatched in 50% of the nests in which eggs were laid, but only 28.9% of these nests produced fledglings. The major causes of nest failure are predation, wind action, and desertion.The nesting study was supplemented by a histological examination of the gonads and associated organs of 307 male and 205 female goldfinches. The results indicate that gonadal activity is cyclical. Gondal recrudescence starts in both sees in July, one month after the winter solstice. Breeding condition is research reached in September and persists until January when the gonads regress quickly. By March the gonads have reached their quiescent winter condition. The study of the male seminal sacs, in conjunction with the results of testicular examination suggest that spermatogenesis may occur in waves during the breeding season. The changes in bill pigmentation, observed throughout the year, bear a clear relationship to the gonadal cycle.The moult sequence in the goldfinch is described in detail. Moult, which is an annual process, starts in December, reaches its peak in February and March, and is completed by mid-May. There is a clear overlap between moulting and nesting.The food of the goldfinch was assessed by an examination of the crop and gizzard contents of 20 specimens from each month of the year, and by field observation. A total of 32 plant species were identified, only one proved to be an Australian native. Small quantities of insect food are eaten at all times, but there is a marked increase in the occurrence of insects in the crop during the breeding season.Finally the topic of introduced species is briefly discussed in the light of recent investigations. This topic is then related to the Goldfinch has succeeded in Australia because of its ability to exploit a vacant, man-made niche for which there were no competitors.

Fish from the freshwater Lower Cretaceous, near Koonwarra, Victoria, Australia : with comments on the palaeo-environment
Creators: name: Waldman, Michael
Publisher: name: Monash University
Year: 2016
Subjects: Uncategorized

description: Freshwater Lower Cretaceous sediments near Koonwarra, Victoria, Australia, and the vertebrate fauna contained in them are described. The evolutionary implications of the fish fauna are considered in detail. It is considered that the palaeo-environment was lacustrine or paludal, and that periodic mass mortality occurred due to anoxic winter conditions beneath an ice-cover ( "winterkill"). The graded laminations present in the fish-bed are thought to be, at least in part, of fairly regular origin and to be due to influxes of silt and clay-laden floodwaters in successive spring seasons. Although such laminae are generally only preserved in deep, cold lakes and wide- spread aquatic arthropod fauna is characteristic of a shallow-water environment today. The number and variety of terrestrial insects, and the small size of the fish also indicates the proximity of shallow waters. The vertebrate fauna consists mainly of fish, although bird feathers are known from the deposit. The discovery of fleas indicates the probable presence of mammals. Five families of fish are known from Koonwarra: Ceratodidae, Coccolepididae, Archaeomaenidae, Koonwarriidae nov. and Leptolepididae. The third and fourth families appear to be limited to Australia. The Ceratodidae are known at Koonwarra from one very poorly preserved specimen of parts of the axial skeleton and an associated skull fragment of Ceratodus sp. The Coccolepididae are represented by Coccolepis woodwardi sp. nov. and are generally small although one fragmentary specimen indicates a ?coccolepid of large size. Coccolepids are rare at Koonwarra. Only one archaeomaenid is known from this site, Wadeichthys oxyops n. gen. et sp. nov. This seems to be the most primitive archaeomaenid known, possessing enamelled scales overall, no ossification in the notochord, an uncompacted caudal skeleton, and most significantly, a pattern of preopercular pit-lines and a sensory canal similar to those of some parasemionotids. Koonwarria manifrons n. gen. et sp. nov. is derived from the archaeomaenids, and is considered to have reached the teleostean grade of organization. The caudal skeleton is compact and homoheterocercal, with elongate urodermals and well formed hypurals. Its scales are completely free of enamel and pit-lines have disappeared from the preopercular and are greatly reduced on the parietal. A new species of Leptolepis, L. koonwarri, is described and found to be closely related to the Jurassic L. talbragarensis from New South Wales. It may also have affinities with the Cretaceous L. diasii from Brazil and Clupavus brodiei from the English Upper Jurassic. L. 'koonwarri is a mosaic form with "advanced" skull features (e.g. loss of postorbital, few preopercular canal branches) whereas the axial and caudal skeleton resemble L. coryphaenoides from the Lower Jurassic of England.

description: We present three newly discovered sub-Jupiter mass planets from the SuperWASP survey: WASP-54b is a heavily bloated planet of mass 0.636$^{+0.025}_{-0.024}$ \mj and radius 1.653$^{+0.090}_{-0.083}$ \rj. It orbits a F9 star, evolving off the main sequence, every 3.69 days. Our MCMC fit of the system yields a slightly eccentric orbit ($e=0.067^{+0.033}_{-0.025}$) for WASP-54b. We investigated further the veracity of our detection of the eccentric orbit for WASP-54b, and we find that it could be real. However, given the brightness of WASP-54 V=10.42 magnitudes, we encourage observations of a secondary eclipse to draw robust conclusions on both the orbital eccentricity and the thermal structure of the planet. WASP-56b and WASP-57b have masses of 0.571$^{+0.034}_{-0.035}$ \mj and $0.672^{+0.049}_{-0.046}$ \mj, respectively; and radii of $1.092^{+0.035}_{-0.033}$ \rj for WASP-56b and $0.916^{+0.017}_{-0.014}$ \rj for WASP-57b. They orbit main sequence stars of spectral type G6 every 4.67 and 2.84 days, respectively. WASP-56b and WASP-57b show no radius anomaly and a high density possibly implying a large core of heavy elements; possibly as high as $\sim$50 M$_{\oplus}$ in the case of WASP-57b. However, the composition of the deep interior of exoplanets remain still undetermined. Thus, more exoplanet discoveries such as the ones presented in this paper, are needed to understand and constrain giant planets' physical properties.

Denying the possibility of giving birth to a child is an issue entwined with the idea of the auctorial self release by using the compulsory recording on paper as a genuine weapon of memory. The article examines both the problems of the literary text as such, the authenticity of the novel, and the hero’s evolution from a traumatic childhood to the survivor’s adulthood, analyzing the complexity of his passage through the triad “birth / life / death”, each of these instances being mirrored in multiple manners by the characters’ denial of assuming his own emptied of meaning Ego being “thrown into the world”.

description: In this Thinking Space essay, we explain why the COVID-19 pandemic makes mobilities research more important than ever. In a time when mobilities have been reconfigured so dramatically, perhaps even leading people to value mobility differently, we need concepts and theories that can help us to attend to and navigate this new situation. Our contention is that mobilities research must recentre the region. Building on earlier work in the mobilities paradigm, we suggest ways that regionality can be conceptualised, and argue that mobilities in our part of the world take distinctive manifestations that warrant our attention. Our essay concludes by pointing to new directions for mobilities research from our region.

description: We study the directional effect of the expected axion dark matter signal in a resonant cavity of an axion haloscope detector, for cavity geometries not satisfying the condition that the axion de Broglie wavelength $λ_a$ is sufficiently larger than the cavity dimensions $L$ for a fully coherent conversion, i.e. $λ_a \gtrsim 2πL$. We focus on long thin cavities immersed in dipole magnets and find, for appropriately chosen cavity lengths, an O(1) modulation of the signal with the cavity orientation with respect the momentum distribution of the relic axion background predicted by the isothermal sphere model for the galactic dark matter halo. This effect can be exploited to design directional axion dark matter detectors, providing an unmistakable signature of the extraterrestrial origin of a possible positive detection. Moreover, the precise shape of the modulation may give information of the galactic halo distribution and, for specific halo models, give extra sensitivity for higher axion masses.

description: When small RNAs are loaded onto Argonaute proteins they can form the RNA-induced silencing complexes (RISCs), which mediate RNA interference. RISC-formation is dependent on a shared pool of Argonaute proteins and RISC loading factors, and is thus susceptible to competition among small RNAs for loading. We present a mathematical model that aims to understand how small RNA competition for the PTR resources affects target gene repression. We discuss that small RNA activity is limited by RISC-formation, RISC-degradation and the availability of Argonautes. Together, these observations explain a number of PTR saturation effects encountered experimentally. We show that different competition conditions for RISC-loading result in different signatures of PTR activity determined also by the amount of RISC-recycling taking place. In particular, we find that the small RNAs less efficient at RISC-formation, using fewer resources of the PTR pathway, can perform in the low RISC-recycling range equally well as their more effective counterparts. Additionally, we predict a novel signature of PTR in target expression levels. Under conditions of low RISC-loading efficiency and high RISC-recycling, the variation in target levels increases linearly with the target transcription rate. Furthermore, we show that RISC-recycling determines the effect that Argonaute scarcity conditions have on target expression variation. Our observations taken together offer a framework of predictions which can be used in order to infer from experimental data the particular characteristics of underlying PTR activity.

description: Genetic association tests involving copy-number variants (CNVs) are complicated by the fact that CNVs span multiple markers at which measurements are taken. The power of an association test at a single marker is typically low, and it is desirable to pool information across the markers spanned by the CNV. However, CNV boundaries are not known in advance, and the best way to proceed with this pooling is unclear. In this article, we propose a kernel-based method for aggregation of marker-level tests and explore several aspects of its implementation. In addition, we explore some of the theoretical aspects of marker-level test aggregation, proposing a permutation-based approach that preserves the family-wise error rate of the testing procedure, while demonstrating that several simpler alternatives fail to do so. The empirical power of the approach is studied in a number of simulations constructed from real data involving a pharmacogenomic study of gemcitabine, and compares favorably with several competing approaches.

description: We revisit the time evolution of a flat and non-flat direction system during inflation. In order to take into account quantum noises in the analysis, we base on stochastic formalism and solve coupled Langevin equations numerically. We focus on a class of models in which tree-level Hubble-induced mass is not generated. Although the non-flat directions can block the growth of the flat direction's variance in principle, the blocking effects are suppressed by the effective masses of the non-flat directions. We find that the fate of the flat direction during inflation is determined by one-loop radiative corrections and non-renormalizable terms as usually considered, if we remove the zero-point fluctuation from the noise terms.

description: We constrain the light extinction properties of Milky Way dust. We investigated the correlations between dust column density as inferred from infrared data and the observed colours of celestial objects at cosmological distances with low levels of colour dispersion. Results derived using colours of quasars, brightest central galaxies, and luminous red galaxies are broadly consistent, indicating a proportionality constant between the reddening E(B-V)=A_B-A_V and the dust column density D^T (given in units of MJy/sr) of p=E(B-V)/D^T=0.02 and a reddening parameter R_V=A_V/E(B-V)=3 with fractional uncertainties of approximately 10%. The data do not provide any evidence for spatial variations in the dust properties, except for a possible hint of scatter in the dust extinction properties at the longest optical wavelengths.

Temperature-dependent dynamical nuclear polarization bistabilities in double quantum dots in the spin-blockade regime

description: The interplay of dynamical nuclear polarization (DNP) and leakage current through a double quantum dot in the spin-blockade regime is analyzed. A finite DNP is built up due to a competition between hyperfine (HF) spin-flip transitions and another inelastic escape mechanism from the triplets, which block transport. We focus on the temperature dependence of the DNP for zero energy-detuning (i.e. equal electrostatic energy of one electron in each dot and a singlet in the right dot). Our main result is the existence of a transition temperature, below which the DNP is bistable, so a hysteretic leakage current versus external magnetic field B appears. This is studied in two cases: (i) Close to the crossing of the three triplet energy levels near B=0, where spin-blockade is lifted due to the inhomogeneity of the effective magnetic field from the nuclei. (ii) At higher B-fields, where the two spin-polarized triplets simultaneously cross two different singlet energy levels. We develop simplified models leading to different transition temperatures T_TT and T_ST for the crossing of the triplet levels and the singlet-triplet level crossings, respectively. We find T_TT analytically to be given solely by the HF couplings, whereas T_ST depends on various parameters and T_ST>T_TT. The key idea behind the existence of the transition temperatures at zero energy-detuning is the suppression of energy absorption compared to emission in the inelastic HF transitions. Finally, by comparing the rate equation results with Monte Carlo simulations, we discuss the importance of having both HF interaction and another escape mechanism from the triplets to induce a finite DNP.

description: In the local Universe, galaxies in groups and clusters contain less gas and are less likely to be forming stars than their field counterparts. This effect is not limited to the central group/cluster regions, but is shown by recent observations to persist out to several virial radii. To gain insight into the extent and cause of this large-scale environmental influence, we use a suite of high-resolution cosmological hydrodynamic simulations to analyse galaxies around simulated groups and clusters of a wide range of mass (log M/M_sun = [13.0, 15.2]). In qualitative agreement with the observations, we find a systematic depletion of both hot and cold gas and a decline in the star forming fraction of galaxies as far out as ~ 5 r200 from the host centre. While a substantial fraction of these galaxies are on highly elliptical orbits and are not infalling for the first time (~ 50 per cent at 2 r200, independent of host mass) or are affected by `pre-processing' (less than 10 per cent of galaxies around groups, increasing to ~ 50 per cent around a massive cluster), even a combination of these indirect mechanisms does not fully account for the environmental influence, particularly in the case of the hot gas content. Direct ram pressure interaction with an extended gas `halo' surrounding groups and clusters is shown to be sufficiently strong to strip the hot gas atmospheres of infalling galaxies out to ~ 5 r200. We show that this influence is highly anisotropic, with ram pressure along filaments enhanced by up to a factor of 100 despite significant co-flow of gas and galaxies.
