The Statistical Discrepancy between the IGM and Dark Matter Fields: One-Point Statistics

description: We investigate the relationship between the mass and velocity fields of the intergalactic medium (IGM) and dark matter. Although the evolution of the IGM is dynamically governed by the gravity of the underlying dark matter field, some statistical properties of the IGM inevitably decouple from those of the dark matter once the nonlinearity of the dynamical equations and the stochastic nature of the field is considered. With simulation samples produced by a hybrid cosmological hydrodynamic/N-body code, which is effective in capturing shocks and complicated structures with high precision, we find that the one-point distributions of the IGM field are systematically different from that of dark matter as follows: 1.) the one-point distribution of the IGM peculiar velocity field is exponential at least at redshifts less than 2, while the dark matter velocity field is close to a Gaussian field; 2.) although the one-point distributions of the IGM and dark matter are similar, the point-by-point correlation between the IGM and dark matter density fields significantly differs on all scales and redshifts analyzed; 3.) the one-point density distributions of the difference between IGM and dark matter fields are highly non-Gaussian and long tailed. These discrepancies violate the similarity between the IGM and dark matter and cannot be explained simply as Jeans smoothing of the IGM. However, these statistical discrepancies are consistent with the fluids described by stochastic-force driven nonlinear dynamics.

description: A rarely studied open cluster, King 1 is observed using the 1.3m telescope equipped with 2k x 4k CCD at the Vainu Bappu Observatory, India. We analyse the photometric data obtained from the CCD observations in both B and V bands. Out of 132 detected stars in the open cluster King 1 field, we have identified 4 stellar variables and 2 among them are reported as newly detected binary systems, in this paper. The parallax values from GAIA DR2 suggest that the open cluster King 1 is at the background of these two detected binary systems, falling along the same line of sight, giving rise to different parallax values. The periodogram analysis was carried out using Phase Dispersion Minimization (PDM) and Lomb Scargle (LS) method for all the detected variables. PHOEBE (PHysics Of Eclipsing BinariEs) is extensively used to model various stellar parameters of both the detected binary systems. Based on the modeling results obtained from this work, one of the binary systems is reported for the first time as an Eclipsing Detached (ED) and the other as an Eclipsing Contact (EC) binary of W-type W UMa.

description: We study compactifications of an infinite family of four-dimensional $\mathcal{N}=1$ SCFTs on a Riemann surface in the presence of arbitrary background fluxes for global symmetries. The four-dimensional parent theories have holographic Sasaki-Einstein duals in type IIB string theory. We compute central charges and R-charges of baryonic operators in the resulting two-dimensional $\mathcal{N}=(0,2)$ theories in three distinct ways: from the field theory side utilizing c-extremization, its recently discovered geometric dual formulation, and holographically using new AdS$_3$ duals of two-dimensional field theories.

description: Anoxygenic photosynthesis is an important pathway for Rhodobacter sphaeroides to produce ATP under oxygen-limiting conditions. The expression of its photosynthesis genes is tightly regulated at transcriptional and post-transcriptional levels in response to light and oxygen signals, to avoid photooxidative stress by the simultaneous presence of pigments, light and oxygen. The puf operon encodes pigment-binding proteins of the light-harvesting complex I (genes pufB and pufA), of the reaction centre (genes pufL and pufM), a scaffold protein (gene pufX) and includes the gene for sRNA PcrX. Segmental differences in the stability of the pufBALMX-pcrX mRNA contribute to the stoichiometry of LHI to RC complexes. With asPcrL we identified the third sRNA and the first antisense RNA that is involved in balancing photosynthesis gene expression in R. sphaeroides. asPcrL influences the stability of the pufBALMX-pcrX mRNA but not of the pufBA mRNA and consequently the stoichiometry of photosynthetic complexes. By base pairing to the pufL region asPcrL promotes RNase III-dependent degradation of the pufBALMX-prcX mRNA. Since asPcrL is activated by the same protein regulators as the puf operon including PcrX it is part of an incoherent feed-forward loop that fine-tunes photosynthesis gene expression.

description: The electromagnetic form factors of the nucleon are calculated at order $q^4$ in the relativistic formulation of baryon chiral perturbation theory. In order to obtain a consistent power counting for the renormalized diagrams we make use of the extended on-mass-shell renormalization scheme which we have discussed in a recent paper. We analyze the Dirac and Pauli form factors, $F_1$ and $F_2$, as well as the electric and magnetic Sachs form factors, $G_E$ and $G_M$. Our results are compared with those obtained in the heavy-baryon approach and in the (relativistic) infrared regularization. In addition, the Sachs form factors are compared with experimental data. We confirm previous findings that a one-loop calculation of the electromagnetic form factors does not generate sufficient curvature for the Sachs form factors $G^p_E$, $G^p_M$, and $G^n_M$. Moreover, the electric form factor of the neutron is very sensitive to higher-order contributions.

 Comments. The specimen was collected during December from Douglas fir and cedar litter.
 Aedeagal characters of Sonoma cardiac are similar to those of S. virgo. The left parameres of each are indistinguishable, but unique among known species of Sonoma. The two can be separated based on the following characters, S. virgo in brackets []: endophallus with large blunt lateral projection (1/4 length of endophallus) in basal 1/3 [small process approximately 1/10 length]; apex of endophallus blunt, no projections [apex of endophallus with two projections, one narrow and one wide]; right paramere without apical projections or setae [right paramere with ventral process with two apical projections, tuft of lateral apical setae present].
 Etymology. The specific epithet is based on the resemblance of the aedeagus to a heart.

description: Machine learning techniques have been paramount throughout the last years, being applied in a wide range of tasks, such as classification, object recognition, person identification, and image segmentation. Nevertheless, conventional classification algorithms, e.g., Logistic Regression, Decision Trees, and Bayesian classifiers, might lack complexity and diversity, not suitable when dealing with real-world data. A recent graph-inspired classifier, known as the Optimum-Path Forest, has proven to be a state-of-the-art technique, comparable to Support Vector Machines and even surpassing it in some tasks. This paper proposes a Python-based Optimum-Path Forest framework, denoted as OPFython, where all of its functions and classes are based upon the original C language implementation. Additionally, as OPFython is a Python-based library, it provides a more friendly environment and a faster prototyping workspace than the C language.

description: Abstract. We define and discuss Savage games, which are ordinal games that are set in L. J. Savage’s framework of purely subjective uncertainty. Every Bayesian game is ordinally equivalent to a Savage game. However, Savage games are free of priors, prob- abilities and payoffs. Players’ information and subjective attitudes toward uncertainty are encoded in the state-dependent preferences over state contingent action profiles. In the games we study player preferences satisfy versions of Savage’s sure thing principle and small event continuity postulate. An axiomatic innovation is a strategic analog of Savage’s null events. We prove the existence of equilibrium in Savage games. This result eschews any notion of objective randomization, convexity, and monotonicity. Applying it to games with payoffs we show that our assumptions are satisfied by a wide range of decision-theoretic models. In this regard, Savage games afford a tractable framework to study attitudes towards uncertainty in a strategic setting. We illustrate our results on the existence of equilibrium by means of examples of games in which players have expected and non-expected utility.

description: We consider pulsed-pump spontaneous parametric downconversion (SPDC) as well as pulsed single- and dual-pump spontaneous four-wave mixing processes in waveguides within a unified Hamiltonian theoretical framework. Working with linear operator equations in $k$-space, our approach allows inclusion of linear losses, self- and cross-phase modulation, and dispersion to any order. We describe state evolution in terms of second-order moments, for which we develop explicit expressions. We use our approach to calculate the joint spectral amplitude of degenerate squeezing using SPDC analytically in the perturbative limit, benchmark our theory against well-known results in the limit of negligible group velocity dispersion, and study the suitability of recently proposed sources for quantum sampling experiments.

description: Microeconomic reform dominated Australian economic policy from the early 1980s until the end of the 20th century. Despite strong claims of success, focusing on the economic expansion since 1992, and rapid productivity growth between 1993-94 and 1998-99, evidence of improvements in the performance of the economy as a whole is weak and inconclusive. For an adequate evaluation of the microeconomic reform period, it is necessary to distinguish several different phases of reform and to evaluate reforms on a case-by-case basis.
Novák's conjecture on cyclic Steiner triple systems and its generalization

description: Novák conjectured in 1974 that for any cyclic Steiner triple systems of order $v$ with $v\equiv 1\pmod{6}$, it is always possible to choose one block from each block orbit so that the chosen blocks are pairwise disjoint. We consider the generalization of this conjecture to cyclic $(v,k,λ)$-designs with $1 \leq λ\leq k-1$. Superimposing multiple copies of a cyclic symmetric design shows that the generalization cannot hold for all $v$, but we conjecture that it holds whenever $v$ is sufficiently large compared to $k$. We confirm that the generalization of the conjecture holds when $v$ is prime and $λ=1$ and also when $λ\leq (k-1)/2$ and $v$ is sufficiently large compared to $k$. As a corollary, we show that for any $k \geq 3$, with the possible exception of finitely many composite orders $v$, every cyclic $(v,k,1)$-design without short orbits is generated by a $(v,k,1)$-disjoint difference family.

Inhomogeneous metallic phase upon disordering a two dimensional Mott insulator

description: We find that isoelectronic disorder destroys the spectral gap in a Mott-Hubbard insulator in 2D leading, most unexpectedly, to a new metallic phase. This phase is spatially inhomogeneous with metallic behavior coexisting with antiferromagnetic long range order. Even though the Mott gap in the pure system is much larger than antiferromagnetic exchange, the spectral gap is destroyed locally in regions where the disorder potential is high enough to overcome the inter-electron repulsion thereby generating puddles where charge fluctuations are enhanced. With increasing disorder, these puddles expand and concomitantly the states at the Fermi energy get extended leading to a metallic phase. We discuss the implications of our results for experiments.

Abundance of damped Lyman-alpha absorbers in cosmological SPH simulations

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We use cosmological smoothed-particle hydrodynamics (SPH) simulations of the Lambda cold dark matter (CDM) model to study the abundance of damped Lyman-alpha absorbers (DLAs) in the redshift range z=0-4.5. We compute the cumulative DLA abundance by using the relation between DLA cross-section and the total halo mass inferred from the simulations. Our approach includes a phenomenological model of galactic wind. We employ the ``conservative entropy'' formulation of SPH, and utilise a series of simulations of varying box-size and particle number to isolate the impact of numerical resolution on our results. We show that the DLA abundance was overestimated in previous studies for three reasons: (1) the overcooling of gas occurring with non-conservative formulations of SPH, (2) a lack of numerical resolution, and (3) an inadequate treatment of feedback. Our new results for the total neutral hydrogen mass density, DLA abundance, and column density distribution function all agree reasonably well with observational estimates at redshift z=3, indicating that DLAs arise naturally from radiatively cooled gas in dark matter haloes that form in a Lambda CDM universe. Our simulations suggest a moderate decrease in DLA abundance by roughly a factor of two from z=4.5 to 3, consistent with observations. A significant decline in abundance from z=3 to z=1, followed by weak evolution from z=1 to z=0, is also indicated, but our low-redshift results need to be interpreted with caution because they are based on coarser simulations than the ones employed at high redshift. Our highest resolution simulation also suggests that the halo mass-scale below which DLAs do not exist is slightly above 10^8 Msun/h at z=3-4, somewhat lower than previously estimated. (abridged)

description: The one-dimensional XXZ model (s=1/2) in a transverse field, with uniform long-range interactions among the transverse components of the spins, is studied. The model is exactly solved by introducing the Jordan-Wigner transformation and the integral Gaussian transformation. The complete critical behaviour and the critical surface for the quantum and classical transitions, in the space generated by the transverse field and the interaction parameters, are presented. The crossover lines for the various classical/quantum regimes are also determined exactly. It is shown that, besides the tricritical point associated with the classical transition, there are also two quantum critical points: a bicritical point where the classical second-order critical line meets the quantum critical line, and a first-order transition point at zero field. It is also shown that the phase diagram for the first-order classical/quantum transitions presents the same structure as for the second-order classical/quantum transitions. The critical classical and quantum exponents are determined, and the internal energy, the specific heat and the isothermal susceptibility,$χ_{T}^{zz},$ are presented for the different critical regimes. The two-spin static and dynamic correlation functions, $$, are also presented, and the dynamic susceptibility, $χ_{q}^{zz}$($ω),$is obtained in closed form. Explicit results are presented at $T=0,$ and it is shown that the isothermal susceptibility, $χ_{T}^{zz},$ is different from the static one, $χ_{q}^{zz}$($0).$ Finally, it is shown that, at $T=0,$ the internal energy close to the first-order quantum transition satisfies the scaling form recently proposed by Continentino and Ferreira.

description: High fidelity iodine spectra provide the wavelength and instrument calibration needed to extract precise radial velocities (RVs) from stellar spectral observations taken through iodine cells. Such iodine spectra are usually taken by a Fourier Transform Spectrometer (FTS). In this work, we investigated the reason behind the discrepancy between two FTS spectra of the iodine cell used for precise RV work with the High Resolution Spectrograph (HRS) at the Hobby-Eberly Telescope. We concluded that the discrepancy between the two HRS FTS spectra was due to temperature changes of the iodine cell. Our work demonstrated that the ultra-high resolution spectra taken by the TS12 arm of the Tull Spectrograph One at McDonald Observatory are of similar quality to the FTS spectra and thus can be used to validate the FTS spectra. Using the software IodineSpec5, which computes the iodine absorption lines at different temperatures, we concluded that the HET/HRS cell was most likely not at its nominal operating temperature of 70 degree Celsius during its FTS scan at NIST or at the TS12 measurement. We found that extremely high resolution echelle spectra (R>200,000) can validate and diagnose deficiencies in FTS spectra. We also recommend best practices for temperature control and nightly calibration of iodine cells.

description: The synthesis conditions of SrTiO$_3$(Co) samples in which cobalt predominantly enters the $A$ or $B$ sites of the perovskite $AB$O$_3$ structure are found. EXAFS studies show that the Co impurity at the $A$ site is off-center and is displaced from the site by 1.0 Å. XANES studies reveal two predominant oxidation states of Co: Co$^{2+}$ at the $A$ site and Co$^{3+}$ at the $B$ site. First-principles calculations of a number of possible cobalt-containing structural defects reveal defects whose properties are compatible with the experimentally observed Co oxidation state, its local structure, magnetic, electrical, and optical properties.

description: 7. Sonoma cobra new species
Fig. 7, 52; Map 10.
 Description. Holotype, male. Measurements: head 0.27 long, 0.36 wide; pronotum 0.41 long, 0.43 wide; elytra 0.40 long, 0.28 wide; antennomeres 1–11 total 0.67; total length 1.80. Body brown, distal portion of antennae, maxillary palpi, and legs paler. Body covered in short setae (less than 1/2 length of the eye).
 Head. Eyes reduced, maximum length in dorsal view 0.75x length of first antennal segment, with approximately 9–10 facets. Antennomere 2 approximately 0.78x width of 1; 3 smallest.
 Thorax. Elytra with indistinct sutural foveae; 2–3 foveae lateral to sutural fovea; single elongate central fovea in basal 1/3. Apparently brachypterous. Metatibia unmodified.
 Abdomen. Tergite IV without microtrichia. Basal lateral foveae obscured, weak if present.
Basal pubescence present on all visible ventrites.
 Aedeagus. Left paramere: longer than endophallus; blade-like apical projection with 4 setae arranged palmately directed posteriorly to mesad. Endophallus: wide as base, narrowing to apex; s-shaped; apical 1/5 perpendicular to aedeagus; subapical wart with two stout setae. Right paramere: elongate apical hook-like process approximately 2/3 length of paramere, directed mesad with 4–5 setae at base.
 Type Material. Holotype, male: * CALIF: Shasta Co. Buckhorn Summit IV.15.1981 T. R.Haig, Coll. / Berlesed from Oak duff (1♂). Deposited in CSAC.
 Geographical Distribution. Sonoma cobra is known from a single specimen collected in Shasta Co., California.
 Comments. The specimen was collected during April from Berlesed oak duff. The reduced eyes, apparent brachyptery, and collection method indicate that the species may be associated with more subterranean habitats than its congeners.
 Aedeagal characters of Sonoma cobra are unique. Lack of elongate latero-apical setae on the parameres separate it from S. spadica, S. repanda, and S. dolabra. The s-shaped endophallus and hook-like apical process on the right paramere will separate S. cobra from all other known species.
 Etymology. Sonoma cobra is named for its unique serpentine endophallus complete with “fang-like” setae. “Cobra” is derived from cobra de capelo, a Portuguese term, and today is commonly used to refer to snakes in the family Elapidae.

description: We analyze in detail the recursive construction of the Seiberg-Witten map and give an exhaustive description of its ambiguities. The local BRST cohomology for noncommutative Yang-Mills theory is investigated in the framework of the effective commutative Yang-Mills type theory. In particular, we show how some of the conformal symmetries get obstructed by the noncommutative deformation.

description: Many scientific investigations of photometric galaxy surveys require redshift estimates, whose uncertainty properties are best encapsulated by photometric redshift (photo-z) posterior probability density functions (PDFs). A plethora of photo-z PDF estimation methodologies abound, producing discrepant results with no consensus on a preferred approach. We present the results of a comprehensive experiment comparing twelve photo-z algorithms applied to mock data produced for The Rubin Observatory Legacy Survey of Space and Time (LSST) Dark Energy Science Collaboration (DESC). By supplying perfect prior information, in the form of the complete template library and a representative training set as inputs to each code, we demonstrate the impact of the assumptions underlying each technique on the output photo-z PDFs. In the absence of a notion of true, unbiased photo-z PDFs, we evaluate and interpret multiple metrics of the ensemble properties of the derived photo-z PDFs as well as traditional reductions to photo-z point estimates. We report systematic biases and overall over/under-breadth of the photo-z PDFs of many popular codes, which may indicate avenues for improvement in the algorithms or implementations. Furthermore, we raise attention to the limitations of established metrics for assessing photo-z PDF accuracy; though we identify the conditional density estimate (CDE) loss as a promising metric of photo-z PDF performance in the case where true redshifts are available but true photo-z PDFs are not, we emphasize the need for science-specific performancemetrics.
Economic Evaluation of the Proposed Free Trade Agreement between Australia and the United States

description: The main points of this submission are: 1. The most important distortions of agricultural trade practised by the US are unaffected by the FTA and are, in effect, endorsed by Australia’s signature to the agreement. 2. Considered in isolation, there is little to commend the proposed agreement. As regards goods, the agreement fails to address the main distortions, such as the US Farm Bill and the protection of the US sugar market while imposing a substantial loss on Australian taxpayers in the form of reduced tariff revenues. Impacts on services are modest. 3. The main adverse impacts of the proposed agreement lie in areas that ought to be outside the scope of a trade agreement. The most notable, as regards the commitments actually entered into, is intellectual property. 4. A Free Trade Agreement between Australia and the United States should be confined to the removal of barriers to trade in goods and services. Issues relating to economic integration should be dealt with in a multilateral context and in a manner that does not prejudice the democratic rights of Australians to control their own social and economic institutions. 5. Parliament must assert its capacity and responsibility to determine Australian law, rather than being bound by the conclusions of closed-door negotiations. Objectionable provisions of the FTA requiring legislative change, such as the extension of copyright, should be rejected. It would then be up to the US Congress to decide whether to accept an agreement which, while still weighted in favour of US interests, was less unbalanced than the current proposal.

Risk and Uncertainty

description: The debate about the dynamics and potential policy responses to asset inflation has intensified in recent years. Some analysts, notably Borio and Lowe, have called for 'subtle' changes to existing monetary targeting frameworks to try to deal with the problems of asset inflation and have attempted to developed indicators of financial vulnerability to aid this process. In contrast, this paper argues that the uncertainties involved in understanding financial market developments and their potential impact on the real economy are likely to remain too high to embolden policy makers. The political and institutional risks associated with policy errors are also significant. The fundamental premise that a liberalised financial system is based on 'efficient' market allocation cannot be overlooked. The corollary is that any serious attempt to stabilize financial market outcomes must involve at least a partial reversal of deregulation

description: We investigate the sensitivity of fits of hadron spectra produced in heavy ion collisions to the choice of statistical hadronization model. We start by giving an overview of statistical model ambiguities, and what they tell us about freeze-out dynamics. We then use Montecarlo generated data to determine sensitivity to model choice. We fit the statistical hadronization models under consideration to RHIC data, and find that a comparison $χ^2$ fits can shed light on some presently contentious questions.

description: Continuous and autonomous measurement of total dissolved inorganic carbon (TCO2) in the oceans is critical for modelling important climate change factors such as ocean uptake of atmospheric CO2 and ocean acidification. Miniaturised chemical analysis systems are therefore required which are small enough for integration into the existing Argo ocean float network for long-term unattended depth profiling of dissolved CO2 with the accuracy of laboratory bench analysers. A microfluidic conductivity-based approach offers the potential for such miniaturisation. Reagent payload for >3 yr operation is a critical parameter. The precise injection of acid into sample, liberating CO2 from seawater, is addressed here. Laser etched microfluidic snake channel restrictors and asymmetric Y meters were fabricated to adjust the metering ratio between seawater and acid simulants. Laser etching conditions were varied to create a range of channel dimensions down to ~75 microns. Channel flow versus pressure measurements were used to determine hydrodynamic resistances which were compared with finite element simulations using a range of cross-section profiles and areas. Microfluidic metering circuits were constructed from variable resistance snake channels and dimensionally symmetric or asymmetric Y-junctions. Sample to acid volume ratios (meter ratio) up to 100:1 have been achieved with 300 microns wide snake channel for lengths > 1m. At the highest pattern resolution, this would require a footprint of > 600 mm2 (6 x10-4 m2). Circuits based solely on asymmetric Y-junctions gave meter ratios up to 16:1 with a footprint cost of < 40 mm2 and precision values of ~0.2%. Further design and fabrication refinements will be required to ensure the structural and dimensional integrity of such small channels in future integration of metering units into full TCO2 analysis microfluidic circuits.
