What will Gaia tell us about the Galactic disk?

Subjects: subject: Astrophysics (astro-ph)

description: Gaia will provide parallaxes and proper motions with accuracy ranging from 10 to 1000 microarcsecond on up to one billion stars. Most of these will be disk stars: for an unreddened K giant at 6 kpc, it will measure the distance accurate to 15% and the transverse velocity to an accuracy of about 1 km/s. Gaia will observe tracers of Galactic structure across the whole HR diagram, including Cepheids, RR Lyrae, white dwarfs, F dwarfs and HB stars. Onboard low resolution spectrophotometry will permit -- in addition to a Teff estimate -- dwarf/giant discrimination, metallicity measurement and extinction determination. For the first time, then, Gaia will provide us with a 3D spatial/properties map and at least a 2D velocity map of these tracers (RVs will be obtained too for brighter stars.) This will be a goldmine of information from which to learn about the origin and evolution of the Galactic disk. I briefly review the Gaia mission, and then show how the expected astrometric accuracies translate into distance and velocity accuracies and statistics. I examine the impact Gaia should have on a few scientific areas relevant to the Galactic disk. I discuss how a better determination of the spiral arm locations and pattern speed, plus a better reconstruction of the Sun's orbit over the past billion years (from integration through the Gaia-measured gravitational potential) will allow us to assess the possible role of spiral arm crossings in ice ages and mass extinctions on the Earth.

Metabolic responses to experimental diving in adult and fetal weddell seals
Creators: name: Murphy, Brian Joseph
Publisher: name: University of British Columbia
Year: 2010

description: Metabolic potentials and activities of the heart, lung and brain were examined in the Antarctic Weddell seal, a species displaying outstanding diving abilities. The activities of representative enzymes in oxidative and fermentative metabolism in both the adult and near-term fetus are similar to those in homologous organs of the adult ox, but the brain and heart in both groups of seals contained elevated levels of lactate dehydrogenase. The isozyme data indicate that all three organs in the adult and fetus have the potential for either lactate production or utilization depending upon metabolic conditions. During experimental diving (up to 30 min) glucose appears to be a critical carbon and energy source for the adult. Glucose is utilized in a mixed aerobic and anaerobic metabolism. The consequent fall in blood glucose levels and rise in lactate levels are due predominantly to peripheral, hypoperfused tissues, but the central organs influence these metabolite pools as well. The brain of the adult seal utilizes glucose at a rate of approximately 0.3 μmol/gm/hr., releasing 20-25% as lactate; this proportion does not change throughout diving-recovery cycles. The lung consumes lactate and thus diminishes its accumulation in the blood during the dive. One, and possibly the main, fate of lactate absorbed by the lung is oxidation since ¹⁴CO₂ is the only measurable derivative found in aortic blood following ¹⁴C-lactate infusion into the right ventricle. During recovery, when blood lactate levels rise above 6 μmol/ml, the brain switches from lactate release to lactate uptake at a rate high enough to readily support the normal metabolic rate of this organ (about 8 μmol ATP/gm/hr). Enzyme and metabolite measurements suggest that the lung and heart also contribute to lactate clearance and re-establishment of metabolic homeostasis following diving in the adult. Blood metabolite analyses suggest little involvement of the majority of free amino acids during dive-recovery cycles. Only alanine and glutamine increase throughout both phases and both probably function as waste nitrogen carriers. Alanine accumulation could also be caused by anerobic catabolism of protein and/or anaerobic-aerobic transitions in tissues such as skeletal muscles. Both the physiological data and metabolite recovery profiles indicate fetal peripheral vasoconstriction and a fully developed diving response as a consequence of maternal diving. The fetus has apparently adapted to long-duration diving by significantly increasing its blood storage capacity of glucose to beyond that of the mother. Furthermore, these elevated stores appear to be under tight regulation during the latter stages of experimental diving.
Multi-Antenna Communication in Ad Hoc Networks: Achieving MIMO Gains with SIMO Transmission

description: The benefit of multi-antenna receivers is investigated in wireless ad hoc networks, and the main finding is that network throughput can be made to scale linearly with the number of receive antennas nR even if each transmitting node uses only a single antenna. This is in contrast to a large body of prior work in single-user, multiuser, and ad hoc wireless networks that have shown linear scaling is achievable when multiple receive and transmit antennas (i.e., MIMO transmission) are employed, but that throughput increases logarithmically or sublinearly with nR when only a single transmit antenna (i.e., SIMO transmission) is used. The linear gain is achieved by using the receive degrees of freedom to simultaneously suppress interference and increase the power of the desired signal, and exploiting the subsequent performance benefit to increase the density of simultaneous transmissions instead of the transmission rate. This result is proven in the transmission capacity framework, which presumes single-hop transmissions in the presence of randomly located interferers, but it is also illustrated that the result holds under several relaxations of the model, including imperfect channel knowledge, multihop transmission, and regular networks (i.e., interferers are deterministically located on grids).

description: Several countries have acquired, over the past decades, large amounts of area covering Airborne Electromagnetic data. Contribution of airborne geophysics has dramatically increased for both groundwater resource mapping and management proving how those systems are appropriate for large-scale and efficient groundwater surveying. We start with processing and inversion of two AEM dataset from two different systems collected over the Spiritwood Valley Aquifer area, Manitoba, Canada respectively, the AeroTEM III (commissioned by the Geological Survey of Canada in 2010) and the “Full waveform VTEM” dataset, collected and tested over the same survey area, during the fall 2011. We demonstrate that in the presence of multiple datasets, either AEM and ground data, due processing, inversion, post-processing, data integration and data calibration is the proper approach capable of providing reliable and consistent resistivity models. Our approach can be of interest to many end users, ranging from Geological Surveys, Universities to Private Companies, which are often proprietary of large geophysical databases to be interpreted for geological and\or hydrogeological purposes. In this study we deeply investigate the role of integration of several complimentary types of geophysical data collected over the same survey area. We show that data integration can improve inversions, reduce ambiguity and deliver high resolution results. We further attempt to use the final, most reliable output resistivity models as a solid basis for building a knowledge-driven 3D geological voxel-based model. A voxel approach allows a quantitative understanding of the hydrogeological setting of the area, and it can be further used to estimate the aquifers volumes (i.e. potential amount of groundwater resources) as well as hydrogeological flow model prediction. In addition, we investigated the impact of an AEM dataset towards hydrogeological mapping and 3D hydrogeological modeling, comparing it to having only a ground based TEM dataset and\or to having only boreholes data.

description: We study the coupled-qubit oscillation driven by an oscillating field. When the period of the non-resonant mode is commensurate with that of the resonant mode of the Rabi oscillation, we show that the controlled-NOT (CNOT) gate operation can be demonstrated. For a weak coupling the CNOT gate operation is achievable by the commensurate oscillations, while for a sufficiently strong coupling it can be done for arbitrary parameter values. By finely tuning the amplitude of oscillating field it is shown that the high fidelity of the CNOT gate can be obtained for any fixed coupling strength and qubit energy gap in experiments.

description: The numerical solution of partial differential equations by discretization techniques is ubiquitous in computational physics. In this work we benchmark this approach in the quantum realm by solving the heat equation for a square plate subject to fixed temperatures at the edges and random heat sources and sinks within the domain. The hybrid classical-quantum approach consists in the solution on a quantum computer of the coupled linear system of equations that result from the discretization step. Owing to the limitations in the number of qubits and their connectivity, we use the Gauss-Seidel method to divide the full system of linear equations into subsystems, which are solved iteratively in block fashion. Each of the linear subsystems were solved using 2000Q and Advantage quantum computers developed by D-Wave Systems Inc. By comparing classical numerical and quantum solutions, we observe that the errors and chain break fraction are, on average, greater on the 2000Q system. Unlike the classical Gauss-Seidel method, the errors of the quantum solutions level off after a few iterations of our algorithm. This is partly a result of the span of the real number line available from the mapping of the chosen size of the set of qubit states. We verified this by using techniques to progressively shrink the range mapped by the set of qubit states at each iteration (increasing floating-point accuracy). As a result, no leveling off is observed. However, an increase in qubits does not translate to an overall lower error. This is believed to be indicative of the increasing length of chains required for the mapping to real numbers and the ensuing limitations of hardware.

description: We use Gemini GMOS-IFU observations of three luminous nearby Seyfert galaxies (Mrk79, Mrk348 and Mrk607) to estimate the electron temperature ($T_{\rm e}$) fluctuations in the inner 0.4-1.1 kpc region of these galaxies. Based on $T_{\rm e}$ determinations through the [O III]$\lambda5007$/$\lambda4363$ emission line ratio of each spaxel, temperature variations are quantified by computing the integrated value of the temperature fluctuation parameter ($t^{\rm 2}$) projected in the plane of the sky $t_{\rm A}^{\rm 2}$, for the first time in Active Galactic Nuclei. We find $t_{\rm A}^{\rm 2}$ values of 0.135, 0.039, and 0.015 for Mrk79, Mrk348, and Mrk607, respectively, which are of the same order or larger than the maximum values reported in star-forming regions and planetary nebulae. Taking into account that $t_{\rm A}^{\rm 2}$ should be considered a lower limit of the total $t^2$ in the nebular volume, the results suggest that the impact of such fluctuations on chemical abundance determinations can be important in some AGNs.

description: In this note we establish a uniform bound for the distribution of a sum $S_n=X_1+\cdots+X_n$ of independent non-homogeneous Bernoulli trials. Specifically, we prove that $σ_n \mathbb{P}(S_n\!=\!j)\leqη$ where $σ_n$ denotes the standard deviation of $S_n$ and $η$ is a universal constant. We compute the best possible constant $η\sim 0.4688$ and we show that the bound also holds for limits of sums and differences of Bernoullis, including the Poisson laws which constitute the worst case and attain the bound. We also investigate the optimal bounds for $n$ and $j$ fixed. An application to estimate the rate of convergence of Mann's fixed point iterations is presented.

About ELASTIC: 

The next generation of wireless communication networks, 6G, is set to revolutionise the scope and potential of networked services by offering ultra-high data rates, ultra-low latency, ultra-reliability, and energy efficiency. However, to fully realise the benefits of 6G, it is crucial to ensure efficient and effective orchestration of its broad range of services and resources.

ELASTIC proposes a novel approach to 6G service orchestration that utilises cutting-edge technologies, including WebAssembly (Wasm), Function-as-a-Service (FaaS), and edge Internet of Things (IoT) orchestration, to enable flexible and efficient serverless deployment of services and functions, dynamic scaling and optimisation of service delivery, and collaborative processing of large datasets in a privacy-preserving manner.

ELASTIC's approach addresses the critical issue of security in 6G orchestration by leveraging Confidential Computing with Trusted Execution Environments (TEEs), and by implementing security policies and service level agreements provided by verticals in edge cloud-native environments and enclaves. To support the development of this approach,

ELASTIC will conduct extensive research on executable isolation, early detection of security vulnerabilities, comparative study of Kubernetes eBPF solutions for observability, and assessment of WASM security properties. ELASTIC will also develop a comprehensive infrastructure that includes an open-source framework and interfaces for cross-platform and portable drivers, low-latency, real-time monitoring of cluster-distributed eBPF/XDP and WASM for security issues, high-speed, secure communication algorithms, distributed state synchronisation algorithms, and an observability framework for WebAssembly-based serverless/FaaS workloads in Kubernetes. The impact of the ELASTIC will be materialised within the active contribution of the project to referent open-source projects (Linux, Kubernetes, etc.), communities, and standards.

 

ELASTIC project has received funding from the Smart Networks and Services Joint Undertaking (SNS JU) under the European Union’s Horizon Europe research and innovation programme under Grant Agreement No 101139067.

description: We report the value of the electric quadrupole moment of $^{209}$Bi extracted from the atomic data. For this, we performed electronic structure calculations for the ground $^4S^o_{3/2}$ and excited $^2P^o_{3/2}$ states of atomic Bi using the Dirac-Coulomb-Breit Hamiltonian and the Fock space coupled cluster method with single, double, and full triple amplitudes for the three-particle Fock space sector. The value of the quadrupole moment of $^{209}$Bi, $Q(^{209}$Bi$)=-418(6)$~mb, derived from the resulting electric field gradient values and available atomic hyperfine splittings is in excellent agreement with molecular data. Due to the availability of the hyperfine constants for unstable isotopes of Bi, current atomic calculation allows also to correct their quadrupole moments.

description: We present an analysis of the lightcurve extracted from Transiting Exoplanet Survey Satellite Full Frame Images of the double-mode RR Lyrae V338 Boo. We find that the fundamental mode pulsation is changing in amplitude across the 54 days of observations. The first overtone mode pulsation also changes, but on a much smaller scale. Harmonics and combinations of the primary pulsation modes also exhibit unusual behavior. Possible connections with other changes in RR Lyrae pulsations are discussed, but a full understanding of the cause of the changes seen in V338 Boo should shed light on some of the most difficult and unanswered questions in stellar pulsation theory, and astrophysics more generally.

description: A number of features of living systems: reversible interactions and weak bonds underlying motor-dynamics; gel-sol transitions; cellular connected fractal organization; asymmetry in interactions and organization; quantum coherent phenomena; to name some, can have a natural accounting via $physical$ interactions, which we therefore seek to incorporate by expanding the horizons of `chemistry-only' approaches to the origins of life. It is suggested that the magnetic 'face' of the minerals from the inorganic world, recognized to have played a pivotal role in initiating Life, may throw light on some of these issues. A magnetic environment in the form of rocks in the Hadean Ocean could have enabled the accretion and therefore an ordered confinement of super-paramagnetic colloids within a structured phase. A moderate H-field can help magnetic nano-particles to not only overcome thermal fluctuations but also harness them. Such controlled dynamics brings in the possibility of accessing quantum effects, which together with frustrations in magnetic ordering and hysteresis (a natural mechanism for a primitive memory) could throw light on the birth of biological information which, as Abel argues, requires a combination of order and complexity. This scenario gains strength from observations of scale-free framboidal forms of the greigite mineral, with a magnetic basis of assembly. And greigite's metabolic potential plays a key role in the mound scenario of Russell and coworkers-an expansion of which is suggested for including magnetism.

description: Informational entropy is often identified as physical entropy. This is surprising because the two quantities are differently defined and furthermore the former is a subjective quantity while the latter is an objective one. We describe the problems and then present a possible view that reconciles the two entropies. Informational entropy of a system is interpreted as physical entropy of a whole composed of both the system and "memories" containing information about the system.

description: We present a versatile, inexpensive and simple optical phase lock for applications in atomic physics experiments. Thanks to all-digital phase detection and implementation of beat frequency pre-scaling, the apparatus requires no microwave-range reference input, and permits phase locking at frequency differences ranging from sub-MHz to 7 GHz (and with minor extension, to 12 GHz). The locking range thus covers ground state hyperfine splittings of all alkali metals, which makes this system a universal tool for many experiments on coherent interaction between light and atoms.

Effects of parasitic copepod, Salmincola californiensis (Dana, 1852) on juvenile sockeye salmon, Oncorhynchus nerka (Walbaum)
Creators: name: Pawaputanon, Kamonporn
Publisher: name: University of British Columbia
Year: 2010

description: Sockeye salmon parasitized with Salmincola californiensis were compared experimentally with unparasitized fish of the same age to determine: (1) its effects on growth; (2) effects on parasitized fish under some environmental stresses and (3) hematological effects of this parasite on its fish host. It was found that average infection levels of 31.25 parasites per fish can reduce the weight of the fish host by almost 34 % within a period of 112 DPI. The rate of increase in length of the infected fish group was slower than that of the non-infected fish group though no statistically significant difference developed during the experimental period. The parasitized fish were found to develop anemia, expressed by the reduction in red cell counts, hemoglobin concentrations and hematocrit values. This anemic condition is attributed to hemodilution of the blood, resulting from damage to the gill and skin epithelia, and, in turn, leading to an osmotic imbalance between the water and the internal fluids. In addition, the progressive reduction of the red cells in the circulating blood may be a result of the absorption of parasite metabolic secretions through the gills or the bulla. Such absorption seems likely because of the observed variations of the cells in the leucocytic system and the significant increase in lymphocytes, neutrophils and "granulocyte cells" in relation to infection time. Furthermore, the blood of the infected fish clotted faster than that of the non-infected fish. During the course of infection a marked increase was also observed in the number of thrombocytes. Parasitized fish were less able to cope with environmental stresses. A water temperature of 21°C was found to be the median lethal temperature o infected fish. The swimming ability of infected fish was also reduced. The parasitized fish reached 50% fatigue when they swam in water of a velocity of 65 cm/sec for only 250 min. The chance of survival for the infected fish in this high water velocity is only 6.6% over the period of 600 min. The ability of the infected fish to transfer from fresh water to salt water was also affected. Mortality of the infected fish increased during this transition and these fish, as indicated by the salinity preference test, also avoided high salinity, suggesting that they may not have been ready to migrate. The critical period of infection where marked differences were found in all the parameters was that period when the parasites reached maximum size and a second infection took place with copepodids hatched from the original group.

description: This paper investigates the distributed optimal output consensus problem of second-order uncertain nonlinear multi-agent systems over weight-unbalanced directed networks. Under the standard assumption that local cost functions are strongly convex with globally Lipschitz gradients, a novel distributed dynamic state feedback controller is developed such that the outputs of all the agents reach the optimal solution to minimize the global cost function which is the sum of all the local cost functions. The controller design is based on a two-layer strategy, where a distributed optimal coordinator and a reference-tracking controller are proposed to address the challenges arising from unbalanced directed networks and uncertain nonlinear functions respectively. A key feature of the proposed controller is that the nonlinear functions containing the uncertainties and disturbances are not required to be globally Lipschitz. Furthermore, by exploiting adaptive control technique, no prior knowledge of the uncertainties or disturbances is required either. Two simulation examples are finally provided to illustrate the effectiveness of the proposed control scheme.

description: In this paper, a general tree algorithm processing a random flow of arrivals is analyzed. Capetanakis--Tsybakov--Mikhailov's protocol in the context of communication networks with random access is an example of such an algorithm. In computer science, this corresponds to a trie structure with a dynamic input. Mathematically, it is related to a stopped branching process with exogeneous arrivals (immigration). Under quite general assumptions on the distribution of the number of arrivals and on the branching procedure, it is shown that there exists a positive constant $λ_c$ so that if the arrival rate is smaller than $λ_c$, then the algorithm is stable under the flow of requests, that is, that the total size of an associated tree is integrable. At the same time, a gap in the earlier proofs of stability in the literature is fixed. When the arrivals are Poisson, an explicit characterization of $λ_c$ is given. Under the stability condition, the asymptotic behavior of the average size of a tree starting with a large number of individuals is analyzed. The results are obtained with the help of a probabilistic rewriting of the functional equations describing the dynamics of the system. The proofs use extensively this stochastic background throughout the paper. In this analysis, two basic limit theorems play a key role: the renewal theorem and the convergence to equilibrium of an auto-regressive process with a moving average.

description: We present an analysis of a new Australia Telescope Compact Array (ATCA) radio-continuum observation of supernova remnant (SNR) G1.9+0.3, which at an age of $\sim$181$\pm$25 years is the youngest known in the Galaxy. We analysed all available radio-continuum observations at 6-cm from the ATCA and the Very Large Array. Using this data we estimate an expansion rate for G1.9+0.3 of 0.563%$\pm$0.078% per year between 1984 and 2009. We note that in the 1980's G1.9+0.3 expanded somewhat slower (0.484% per year) than more recently (0.641% per year). We estimate that the average spectral index between 20-cm and 6-cm, across the entire SNR is $α=-0.72\pm 0.26$ which is typical for younger SNRs. At 6-cm, we detect an average of 6% fractionally polarised radio emission with a peak of 17%$\pm$3%. The polarised emission follows the contours of the strongest of X-ray emission. Using the new equipartition formula we estimate a magnetic field strength of B$\approx 273μ$G, which to date, is one of the highest magnetic field strength found for any SNR and consistent with G1.9+0.3 being a very young remnant. This magnetic field strength implies a minimum total energy of the synchrotron radiation of E$_{\textrm{min}} \approx$ 1.8$\times$10$^{48}$ ergs.

description: We report measurements of quasiparticle relaxation dynamics in the high-temperature superconductor (Ba,K)Fe$_{2}$As$_{2}$ in optimally doped, underdoped and undoped regimes. In the underdoped sample, spin-density wave (SDW) order forms at $\sim$85 K, followed by superconductivity at $\sim$ 28 K. We find the emergence of a normal-state order that suppresses SDW at a temperature $T^{\ast} \sim$ 60 K and argue that this normal-state order is a precursor to superconductivity.

Negative refraction in active and passive media: a discussion of various criteria

description: There are three widely-used conditions for characterizing negative refraction in isotropic dielectric-magnetic materials. Here we demonstrate that whilst all the different conditions are equivalent for purely passive media, they are distinct if active media are considered. Further, these criteria can also be applied to negative refraction in acoustic materials, where we might replace the dielectric permittivity $ε$ with a bulk modulus $κ$, and the magnetic permeability $μ$ with the mass density $ρ$.

description: The consortium NANOGrav discovered the isotropic gravitational wave background (GWB) with an amplitude of $h\sim 10^{-15}$ and a frequency of $f\sim 10^{-8}$ Hz using observations of millisecond pulsars. We hypothesize that the GWB is relic radiation left over from the merging stellar mass black holes (SBHs) during Big Crunch at $z\sim 10^{10}$. The relic gravitational waves are similar to the gravitational waves with $f\sim 10^2$ Hz discovered by LIGO in 2015, taking into account a decrease in frequency by a factor $\sim 10^{10}$ due to the expansion of the Universe. We take as a basis the observed spectrum of 139 SBHs, discovered by the LIGO observatory. Our model explains well all the observed features of the GWB. Unlike all other GWB models, our model predicts a sharp decrease in the GWB amplitude at frequencies $f>3.5*10^{-8}$ Hz, reflecting the deficit of SBHs with masses $<4M_\odot$. The SBMH mergers at Big Crunch should generate yet undiscovered GWB with a frequency of $f\sim 10^{-(14-17)}$ Hz.

“I Am not Here for Fun”: The Satirical Facebook Group Royalists Marketplace, Queer TikToking, and the New Democracy Movement in Thailand
Creators: name: Schaffar, Wolfram
Publisher: name: Austrian Journal of South-East Asian Studies

description: Pavin Chachavalpongpun is an associate professor at the Center for Southeast Asian Studies at Kyoto University. He has published extensively on Thailand and Southeast Asian politics. He is also politically active and does not shy away from discussing and criticizing the monarchy, which for a long time was taboo – in academia as well as in political campaigns. In April 2020, Prof. Pavin Chachavalpongpun founded the Facebook group Royalists Marketplace (รอยัลลิสต์มาร์เก็ตเพลส). The name alludes to other Facebook groups, like the Chulalongkorn Marketplace or Thammasat Marketplace, which were set up by former students of those universities as platforms for selling and purchasing items, and socializing in times of the COVID-19 lockdown. Pavin’s group, however, is a persiflage of these initiatives. He developed a unique style of political communication, with a distinct mixture of memes, TikTok and Youtube videos, together with serious academic debates, which made his Facebook group the leading platform for criticism of the monarchy. This interview took place via Zoom between Kyoto and Cologne at the end of August 2020. Information on the dynamic developments that have unfolded since then has been added.

description: Predictions of the Cabibbo-Kobayashi-Maskawa (CKM) parameters are investigated in detail in recent predictive models which are based on low-energy non-abelian discrete family symmetries. Some of the models can already be excluded at the present precision of the determination of the CKM parameters, while some of them seem to survive. We find that to make the uncertainties in the predictions comparable with the assumed uncertainties of $\sim 1^{\circ}$ and $\sim 2^{\circ}$ in $ϕ_2$ and $ϕ_3$, respectively, at about 50 inverse atto barn achieved at a feature B factory, it is necessary to reduce the uncertainties in the quark masses, especially that of the strange quark mass by more than 60%.
