description: Reinforcement learning (RL) for robotics is challenging due to the difficulty in hand-engineering a dense cost function, which can lead to unintended behavior, and dynamical uncertainty, which makes exploration and constraint satisfaction challenging. We address these issues with a new model-based reinforcement learning algorithm, Safety Augmented Value Estimation from Demonstrations (SAVED), which uses supervision that only identifies task completion and a modest set of suboptimal demonstrations to constrain exploration and learn efficiently while handling complex constraints. We then compare SAVED with 3 state-of-the-art model-based and model-free RL algorithms on 6 standard simulation benchmarks involving navigation and manipulation and a physical knot-tying task on the da Vinci surgical robot. Results suggest that SAVED outperforms prior methods in terms of success rate, constraint satisfaction, and sample efficiency, making it feasible to safely learn a control policy directly on a real robot in less than an hour. For tasks on the robot, baselines succeed less than 5% of the time while SAVED has a success rate of over 75% in the first 50 training iterations.

Theoretical approaches to understanding China and India in peacekeeping operations

Year: 2013
Subjects: subject: 300 Sozialwissenschaften::320 Politikwissenschaft

description: This paper outlines various theoretical approaches used to conceptualize peacekeeping operations (PKO) in International Relations Theory, and compares these general approaches with Indian and Chinese participation and practices. The analysis follows two main trajectories: 1) How is peacekeeping understood in Chinese and Indian conceptions of international relations? 2) How are peacekeeping operations operationalized and carried out? While China and India tend to differ at the level of their contributions, there is a commonality of the broad theoretical underpinnings of their participation. Westphalian principles of sovereignty and non-interference remain at the core of engagement for both these actors. At the same time, as demonstrated by Indian support for the UNAMA missions and Chinese voting behavior on Libyan and Syrian missions at the UNSC, both countries have become more pragmatic in their foreign policy approach to peacekeeping as future “responsible powers”. Chinese and Indian involvement in different types of missions which go beyond traditional peacekeeping thus point to a change in the international outlook and evolving foreign policy of both these countries, possibly in tandem with their rising global status and the need to utilize peacekeeping as a means of greater participation in the global governance system.

description: The quantization of the electronic two site system interacting with a vibration is considered by using as the integrable reference system the decoupled oscillators resulting from the adiabatic approximation. A specific Bloch projection method is applied which demonstrates how besides some regular regions in the fine structure of the spectrum and the associated eigenvectors irregularities appear when passing from the low to the high coupling case. At the same time even for strong coupling some of the regular structure of the spectrum rooted in the adiabatic potentials is kept intact justifying the classification of this situation as incipience of quantum chaos.

description: The Nishimori point of the random bond Ising model is a prototype of renormalization group fixed points with strong disorder. We show that the exact correlation length and crossover critical exponents at this point can be identified in two and three spatial dimensions starting from properties of the Nishimori line. These are the first exact exponents for frustrated random magnets, a circumstance to be also contrasted with the fact that the exact exponents of the Ising model without disorder are not known in three dimensions. Our considerations extend to higher dimensions and models other than Ising.

THE FORMATION OF CARBON DIOXIDE HYDRATE IN SOLID SUSPENSIONS AND ELECTROLYTES

description: Evaluation of host geologic sediment interactions with carbon dioxide is very important in sequestration strategies. The objective of the study is to experimentally investigate the effects of different soil mineral types on carbon dioxide hydrate formation. At isothermal, isochoric, and isobaric conditions, batch experiments were conducted with different types of solids (bentonite, kaolinite, nontronite, pyrite, and soil) and electrolytes (NaCl, KCl, CaCl2, and MgCl2) to measure carbon dioxide hydrate formation times. A 50 mL pressurized vessel was used for the experiment by bubbling gaseous CO2 into the solid suspension. We observed that the formation time of carbon dioxide hydrate was dependent on the reactor temperature (273.4 K and 277.1 K) and types of solid and electrolyte. A clear peak was observed in the temperature profile of each experimental run and determined as the hydrate formation time. This is due to the initiation of the hydrate crystallization and latent heat release at the hydrate formation time. The temperature profiles vary significantly with respect to the types of solids and electrolytes. As crystallization initiates, peaks were observed at higher temperatures in pyrite and soil suspensions. The results showed that hydrate formation times for clay minerals in water were approximately twice and 10 times faster than that for pyrite and soil, respectively. The rates of gas consumption were able to be determined by the pressure monitoring. The kaolinite appeared to have the fastest gas consumption rate among the clay mineral suspensions, which was 2.4 times and 7.4 times faster than nontronite and bentonite, respectively. Results from these experiments seem to provide an insight on the formation and growth of carbon dioxide hydrate, once sequestered into the sea bed sediments under the deep sea environment.

Energy Regulation by the Skeleton: Exploring the Role of Bone-Derived LCN2

description: Life relies on the integration of external environmental stimuli and internal signals to balance fluctuations in nutrient availability to achieve homeostasis. Bone has recently emerged as a pleiotropic endocrine organ that secretes at least two hormones, FGF23 and osteocalcin, which regulate kidney function and glucose homeostasis, respectively. These findings have raised the question of whether other bone-derived hormones exist and what their potential functions are. Here we identify, through molecular and genetic analyses in mice, lipocalin 2 (LCN2) as an osteoblast-enriched, secreted protein. Loss- and gain-of-function experiments in mice demonstrate that osteoblast-derived LCN2 maintains glucose homeostasis by inducing insulin secretion and improves glucose tolerance and insulin sensitivity. In addition, osteoblast-derived LCN2 inhibits food intake. LCN2 crosses the blood–brain barrier, binds to the melanocortin 4 receptor (MC4R) in the paraventricular and ventromedial neurons of the hypothalamus and activates an MC4R-dependent anorexigenic (appetite-suppressing) pathway. These results identify LCN2 as a bone-derived hormone with metabolic regulatory effects, which suppresses appetite in a MC4R-dependent manner, and show that the control of appetite is an endocrine function of bone. Furthermore, we show that serum LCN2 levels correlate with insulin levels and β-cell function, indices of healthy glucose metabolism, in genetic and diet-induced mouse models of obesity and in obese, healthy or pre-diabetic patients. However, LCN2 serum levels also correlate with body mass index (BMI) and insulin resistance in the same patients; and are increased in obese mice. To dissect this apparent discrepancy, we examined LCN2 effects in hyperphagia and β -cell function mouse models of obesity or β -cell destruction. Silencing Lcn2 expression increases hyperphagia, fat and body weight and worsens β -cell function and general metabolic dysfunction in obese, leptin receptor-deficient mice. Conversely, LCN2 increases β-cell numbers and promotes β-cell function after streptozotocin-induced β -cell failure by (STZ) and acts as a growth factor necessary for β -cell adaptation to higher metabolic load in mice. These results support a protective role for LCN2 in obesity-induced glucose intolerance and insulin resistance that stem from its ability to decrease food intake and promote adaptive β-cell proliferation.

description: Non-relativistic potential models are considered of the pure power V(r)=sgn(q) r^q and logarithmic V(r)=ln(r) types. It is shown that, from the spectral viewpoint, these potentials are actually in a single family. The log spectra can be obtained from the power spectra by the limit q --> 0 taken in a smooth representation P(n,l,q) for the eigenvalues E(n,l,q). A simple approximation formula is developed which yields the first thirty eigenvalues with error < 0.04%.

description: This study explores why energy prices in the Philippines are high. A comparison of the components of energy cost among selected cities in Asia reveals that Manila has the third highest generation cost, highest grid cost and the third highest value added tax imposed on energy. An examination of a residential bill in Manila further reveals an energy cost component unique to the Philippines. At least 15 percent of a residential electric bill comprises of miscellaneous charges that represent subsidies for the elderly and marginalized end-consumers, rural electrification, subsidies to incentivize development of renewable energy and the cost of debt incurred by the government in the past. The history of the energy industry in the Philippines reveals that loose implementation policies especially at the local level, external economic factors such as currency depreciation and increase in interest rates and oil prices, ineffective demand projections and poor pipeline planning as well as political influences led to the massive debt incurred by the government. Due to the governmentUs fiscal constraints, the industry was privatized. Pricing is regulated by the Energy Regulatory Commission but oligopolies and conflicts of interest in the industry, as well as the current pricing mechanisms suppress demand and impede the reduction of energy prices. Absence of public participation leaves the general public at a disadvantage because the burden of paying for miscellaneous energy costs falls on them.

How mobile robots can self-organise a vocabulary

Subjects: subject: 400 Sprache::410 Linguistik

description: One of the hardest problems in science is the symbol grounding problem, a question that has intrigued philosophers and linguists for more than a century. With the rise of artificial intelligence, the question has become very actual, especially within the field of robotics. The problem is that an agent, be it a robot or a human, perceives the world in analogue signals. Yet humans have the ability to categorise the world in symbols that they, for instance, may use for language. This book presents a series of experiments in which two robots try to solve the symbol grounding problem. The experiments are based on the language game paradigm, and involve real mobile robots that are able to develop a grounded lexicon about the objects that they can detect in their world. Crucially, neither the lexicon nor the ontology of the robots has been preprogrammed, so the experiments demonstrate how a population of embodied language users can develop their own vocabularies from scratch.

description: The level of abstraction at which application experts reason about linear algebra computations and the level of abstraction used by developers of high-performance numerical linear algebra libraries do not match. The former is conveniently captured by high-level languages and libraries such as Matlab and Eigen, while the latter expresses the kernels included in the BLAS and LAPACK libraries. Unfortunately, the translation from a high-level computation to an efficient sequence of kernels is a task, far from trivial, that requires extensive knowledge of both linear algebra and high-performance computing. Internally, almost all high-level languages and libraries use efficient kernels; however, the translation algorithms are too simplistic and thus lead to a suboptimal use of said kernels, with significant performance losses. In order to both achieve the productivity that comes with high-level languages, and make use of the efficiency of low level kernels, we are developing Linnea, a code generator for linear algebra problems. As input, Linnea takes a high-level description of a linear algebra problem and produces as output an efficient sequence of calls to high-performance kernels. In 25 application problems, the code generated by Linnea always outperforms Matlab, Julia, Eigen and Armadillo, with speedups up to and exceeding 10x.

description: We present and apply Gaussbock, a new embarrassingly parallel iterative algorithm for cosmological parameter estimation designed for an era of cheap parallel computing resources. Gaussbock uses Bayesian nonparametrics and truncated importance sampling to accurately draw samples from posterior distributions with an orders-of-magnitude speed-up in wall time over alternative methods. Contemporary problems in this area often suffer from both increased computational costs due to high-dimensional parameter spaces and consequent excessive time requirements, as well as the need for fine tuning of proposal distributions or sampling parameters. Gaussbock is designed specifically with these issues in mind. We explore and validate the performance and convergence of the algorithm on a fast approximation to the Dark Energy Survey Year 1 (DES Y1) posterior, finding reasonable scaling behavior with the number of parameters. We then test on the full DES Y1 posterior using large-scale supercomputing facilities, and recover reasonable agreement with previous chains, although the algorithm can underestimate the tails of poorly-constrained parameters. Additionally, we discuss and demonstrate how Gaussbock recovers complex posterior shapes very well at lower dimensions, but faces challenges to perform well on such distributions in higher dimensions. In addition, we provide the community with a user-friendly software tool for accelerated cosmological parameter estimation based on the methodology described in this paper.

description: We look in detail at the process of mapping an astrophysical initial model from a stellar evolution code onto the computational grid of an explicit, Godunov type code while maintaining hydrostatic equilibrium. This mapping process is common in astrophysical simulations, when it is necessary to follow short-timescale dynamics after a period of long timescale buildup. We look at the effects of spatial resolution, boundary conditions, the treatment of the gravitational source terms in the hydrodynamics solver, and the initialization process itself. We conclude with a summary detailing the mapping process that yields the lowest ambient velocities in the mapped model.

description: Kinesin motors can induce a buckling instability in a microtubule with a fixed minus end. Here we show that by modifying the surface with a protein-repellent functionalization and using clusters of kinesin motors, the microtubule can exhibit persistent oscillatory motion, resembling the beating of sperm flagella. The observed period is of the order of 1 min. From the experimental images we theoretically determine a distribution of motor forces that explains the observed shapes using a maximum likelihood approach. A good agreement is achieved with a small number of motor clusters acting simultaneously on a microtubule. The tangential forces exerted by a cluster are mostly in the range 0 - 8 pN towards the microtubule minus end, indicating the action of 1 or 2 kinesin motors. The lateral forces are distributed symmetrically and mainly below 10 pN, while the lateral velocity has a strong peak around zero. Unlike well-known models for flapping filaments, kinesins are found to have a strong "pinning" effect on the beating filaments. Our results suggest new strategies to utilize molecular motors in dynamic roles that depend sensitively on the stress built-up in the system.

BIOLOGY. — No information.
ETYMOLOGY. — The patronymic name is to draw attention that the genus occurs also on Vanuatu, as the genus was known only from Fiji.
 REMARKS. — There are numerous species of Levoecus from Fiji in the collections of Landcare Research, Auckland, but the species described from Vanuatu is not amongst the Fijian ones. Marshall (1956) reported also Vanuatu for Levoecus without mentioning or describing any species for these islands.

description: Several popular cosmological models predict that most of the baryonic mass in the local universe is located in filamentary and sheet-like structures associated with galaxy overdensities. This gas is expected to be gravitationally heated to ~10^6 K and therefore emitting in the soft X-rays. We have detected diffuse soft X-ray structures in a high Galactic latitude ROSAT field after point source subtraction and correction for Galactic absorption. These diffuse structures have an X-ray energy distribution that is much softer than expected from clusters, groups or unresolved emission from AGNs, but are consistent with that expected from a diffuse warm intergalactic medium. To discriminate between a Galactic or extragalactic nature of the diffuse gas we have correlated the soft X--map with multiband optical images in this field. We have found a significant overdensity of galaxies in correspondence with the strongest diffuse X-ray structure. The photometric redshift distribution of the galaxies over the X-ray peak has an excess over field galaxies at z~0.45. This result strongly suggests that the diffuse X-ray flux is due to extragalactic emission by warm gas associated with an overdense galaxy region at z~0.45.

description: Dominions, in the sense of Isbell, are investigated in the context of decomposable varieties of groups. An upper and lower bound for dominions in such a variety is given in terms of the two varietal factors, and the internal structure of the group being analyzed. Finally, the following result is established: If a variety ${\cal N}$ has instances of nontrivial dominions, then for any proper subvariety ${\cal Q}$ of ${\cal G}roup$, ${\cal NQ}$ also has instances of nontrivial dominions.

description: Quantum communication brings radically new capabilities that are provably impossible to attain in any classical network. Here, we take the first step from a physics experiment to a fully fledged quantum internet system. We propose a functional allocation of a quantum network stack and construct the first physical and link layer protocols that turn ad-hoc physics experiments producing heralded entanglement between quantum processors into a well-defined and robust service. This lays the groundwork for designing and implementing scalable control and application protocols in platform-independent software. To design our protocol, we identify use cases, as well as fundamental and technological design considerations of quantum network hardware, illustrated by considering the state-of-the-art quantum processor platform available to us (Nitrogen-Vacancy (NV) centers in diamond). Using a purpose built discrete-event simulator for quantum networks, we examine the robustness and performance of our protocol using extensive simulations on a super-computing cluster. We perform a full implementation of our protocol, where we successfully validate the physical simulation model against data gathered from the NV hardware. We first observe that our protocol is robust even in a regime of exaggerated losses of classical control messages with only little impact on the performance of the system.We proceed to study the performance of our protocols for 169 distinct simulation scenarios, including tradeoffs between traditional performance metrics such as throughput and the quality of entanglement. Finally, we initiate the study of quantum network scheduling strategies to optimize protocol performance for different use cases.

title: PEX13 Mutant Mice as Models of Zellweger Syndrome Neuropathogenesis and Peroxisomal Matrix Protein Import
Creators: name: Meshram, Mallika
Publisher: name: Griffith University

Subjects: subject: Zellweger Syndrome Neuropathogenesis
subject: Peroxisomal Matrix Protein Import

description: Peroxisomes are essential for the developing brain as the loss of functional peroxisomes leads to mild to severe Peroxisome Biogenesis Disorders (PBD) with significant neurological involvement. Zellweger Syndrome (ZS) represents the most severe form of PBDs resulting from a mutation in PEX genes, including PEX13, which encode peroxins necessary for peroxisome biogenesis. ZS patients exhibit a range of clinical abnormalities including hypotonia, multi-organ failure, abnormal metabolic profile with significant neuropathologies and death within a year after birth. As mutation in Pex13 in humans result in ZS, animal models with ubiquitous and targeted disruption of PEX13 were generated in order to understand the unifying molecular pathogenesis of ZS. PEX13 knockout (KO) and brain specific disruption of PEX13 mice (referred as PEX13 brain mutant) were developed in our laboratory and applied as experimental tools previously and in this thesis, to explore the molecular and cellular basis of ZS neuropathology. The PEX13 KO mice, exhibits severe ZS phenotype which includes hypotonia, neuronal migration defect, impaired fatty acid oxidation and plasmalogen synthesis, and early neonatal death.

description: The detection of gravitational waves with ground-based laser interferometers has opened a new window to test and constrain General Relativity (GR) in the strong, dynamical, and non-linear regime. In this paper, we follow an agnostic approach and we study the quasi-normal modes of gravitational perturbations of Johannsen black holes under the assumptions of the validity of the Einstein Equations and of low values of the black hole spin parameter and deformation parameters. We find that the deformation parameter $α_{13}$ has a stronger impact on the quasi-normal modes than the other leading order deformation parameters ($α_{22}$, $α_{52}$, and $ε_{3}$). We derive a fitting formula for the fundamental modes with $l=2$ and $l=3$ for the deformation parameter $α_{13}$ valid in the slow rotation approximation ($a_* < 0.4$). Finally, we constrain $α_{13}$ from the event GW170104; within our analysis, we find that the data of GW170104 are consistent with the predictions of GR.

description: In this work we derive a mathematical model for an open system that exchanges particles and momentum with a reservoir from their joint Hamiltonian dynamics. The complexity of this many-particle problem is addressed by introducing a countable set of n-particle phase space distribution functions just for the open subsystem, while accounting for the reservoir only in terms of statistical expectations. From the Liouville equation for the full system we derive a set of coupled Liouville-type equations for the n-particle distributions by marginalization with respect to reservoir states. The resulting equation hierarchy describes the external momentum forcing of the open system by the reservoir across its boundaries, and it covers the effects of particle exchanges, which induce probability transfers between the n- and (n+1)-particle distributions. Similarities and differences with the Bergmann-Lebowitz model of open systems (P.G.Bergmann, J.L. Lebowitz, Phys.Rev., 99:578--587 (1955)) are discussed in the context of the implementation of these guiding principles in a computational scheme for molecular simulations.
