description: Post-fertilization epigenome reprogramming erases epigenetic marks transmitted through gametes and establishes new marks during mid-blastula stages. The mouse embryo undergoes dynamic DNA methylation reprogramming after fertilization, while in zebrafish, the paternal DNA methylation pattern is maintained throughout the early embryogenesis and the maternal genome is reprogrammed in a pattern similar to that of sperm during the mid-blastula transition. Here, we show DNA methylation dynamics in medaka embryos, the biomedical model fish, during epigenetic reprogramming of embryonic genome. The sperm genome was hypermethylated and the oocyte genome hypomethylated prior to fertilization. After fertilization, the methylation marks of sperm genome were erased within the first cell cycle and embryonic genome remained hypomethylated from the zygote until 16-cell stage. The DNA methylation level gradually increased from 16-cell stage through the gastrula. The 5-hydroxymethylation (5hmC) levels showed an opposite pattern to DNA methylation (5-mC). The mRNA levels for DNA methyltransferase (DNMT) 1 remained high in oocytes and maintained the same level through late blastula stage and was reduced thereafter. DNMT3BB.1 mRNA levels increased prior to remethylation. The mRNA levels for ten-eleven translocation methylcytosine dioxygenases (TET2 & TET3) were detected in sperm and embryos at cleavage stages, whereas TET1 and TET3 mRNAs decreased during gastrulation. The pattern of genome methylation in medaka was identical to mammalian genome methylation but not to zebrafish. The present study suggests that a medaka embryo resets its DNA methylation pattern by active demethylation and by a gradual remethylation similar to mammals.

description: This paper addresses practical implementation of summing out, expanding, and reordering of messages in Local Conditioning (LC) for undirected networks. In particular, incoming messages conditioned on potentially different subsets of the receiving node's relevant set must be expanded to be conditioned on this relevant set, then reordered so that corresponding columns of the conditioned matrices can be fused through element-wise multiplication. An outgoing message is then reduced by summing out loop cutset nodes that are upstream of the outgoing edge. The emphasis on implementation is the primary contribution over the theoretical justification of LC given in Fay et al. Nevertheless, the complexity of Local Conditioning in grid networks is still no better than that of Clustering.

Boundary layer, accretion disk and X-ray variability in luminous LMXBs

description: Using Fourier frequency resolved X-ray spectroscopy we study short term spectral variability in luminous LMXBs. With RXTE/PCA observations of 4U1608--52 and GX340+0 on the horizontal/normal branch of the color-intensity diagram we show that aperiodic and quasiperiodic variability on ~ sec-msec time scales is caused primarily by variations of the luminosity of the boundary layer. The emission of the accretion disk is less variable on these time scales and its power density spectrum follows Pdisk(f) ~ 1/f law, contributing to observed flux variation at low frequencies and low energies only. The kHz QPOs have the same origin as variability at lower frequencies, i.e. independent of the nature of the "clock", the actual luminosity modulation takes place on the neutron star surface, The boundary layer spectrum remains nearly constant in the course of the luminosity variations and is represented to certain accuracy by the Fourier frequency resolved spectrum. In the considered range Mdot ~ (0.1-1)Mdot_Edd it depends weakly on the global mass accretion rate and in the limit Mdot ~ Mdot_Edd is close to Wien spectrum with kT ~ 2.4 keV (in the distant observer's frame). The spectrum of the accretion disk emission is significantly softer and in the 3--20 keV range is reasonably well described by a relativistic disk model with a mass accretion rate consistent with the value inferred from the observed X-ray flux.

description: This cumulative dissertation lays the conceptual groundwork for fostering young people’s political competencies, focusing on the politically relevant task of deciding on welfare support. More specifically, it examines which information is relevant and which misinformation is harmful to competence in welfare support decisions, and how these insights can be practically implemented. Addressing these questions is crucial, as democracies depend on both well-designed institutions and politically competent citizens. Young people are particularly significant in this context, as the impressionable years are crucial for the foundations of the making of citizens. Yet, fostering political competencies proves challenging, given ongoing debates over what constitutes “competence” and what role knowledge and misinformation play in competence development. This dissertation tackles these issues by developing a task-based approach to political competence and applying it to welfare support decisions in three papers. Through a comprehensive literature review, paper 1 introduces the “knowledge-deservingness-attitudes nexus,” linking knowledge and misinformation to welfare attitudes via the deservingness heuristic. It proposes a new research agenda centered on young people and welfare-state-related beliefs. Papers 2 and 3 follow this agenda with empirical case studies based on an original survey of over 1,500 adolescents in secondary schools in the German-speaking part of Switzerland. Paper 2 confirms that young people rely on deservingness considerations to inform their welfare support decisions. Moreover, the employed survey experiment reveals interesting differences from previous adult-centered studies (e.g., the absence of a migrant deservingness gap), indicating potential cohort effects. Paper 3 defines a criterion for competence in welfare support decisions, identifies unemployment-related beliefs and misinformation associated with deservingness, explores sources of influential misinformation, and provides educational policy recommendations. Overall, the dissertation contributes to the literature on political competence and political education, welfare attitudes, and political socialization, offering insights relevant beyond the Swiss context. At the same time, it raises deeper theoretical questions about how to define and evaluate truth in the political sphere, particularly when dealing with contested or uncertain claims.

description: The npm registry is one of the pillars of the JavaScript and TypeScript ecosystems, hosting over 1.7 million packages ranging from simple utility libraries to complex frameworks and entire applications. Due to the overwhelming popularity of npm, it has become a prime target for malicious actors, who publish new packages or compromise existing packages to introduce malware that tampers with or exfiltrates sensitive data from users who install either these packages or any package that (transitively) depends on them. Defending against such attacks is essential to maintaining the integrity of the software supply chain, but the sheer volume of package updates makes comprehensive manual review infeasible. We present Amalfi, a machine-learning based approach for automatically detecting potentially malicious packages comprised of three complementary techniques. We start with classifiers trained on known examples of malicious and benign packages. If a package is flagged as malicious by a classifier, we then check whether it includes metadata about its source repository, and if so whether the package can be reproduced from its source code. Packages that are reproducible from source are not usually malicious, so this step allows us to weed out false positives. Finally, we also employ a simple textual clone-detection technique to identify copies of malicious packages that may have been missed by the classifiers, reducing the number of false negatives. Amalfi improves on the state of the art in that it is lightweight, requiring only a few seconds per package to extract features and run the classifiers, and gives good results in practice: running it on 96287 package versions published over the course of one week, we were able to identify 95 previously unknown malware samples, with a manageable number of false positives.

description: Magnetic helices and skyrmions in noncentrosymmetric magnets are representative examples of chiral spin textures in solids. Their spin swirling direction, often termed as the magnetic helicity and defined as either left-handed or right-handed, is uniquely determined by the Dzyaloshinskii-Moriya interaction (DMI) in fixed chirality host crystals. Thus far, there have been relatively few investigations of the DMI in metallic magnets as compared with insulating counterparts. Here, we focus on the metallic magnets Co$_{8-x}$Fe$_x$Zn$_8$Mn$_4$ (0 $\leq$ $x$ $\leq$ 4.5) with a $β$-Mn-type chiral structure and find that as $x$ varies under a fixed crystal chirality, a reversal of magnetic helicity occurs at $x_\mathrm{c}$ $\sim$ 2.7. This experimental result is supported by a theory based on first-principles electronic structure calculations, demonstrating the DMI to depend critically on the electron band filling. Thus by composition tuning our work shows the sign change of the DMI with respect to a fixed crystal chirality to be a universal feature of metallic chiral magnets.

description: Extreme weather resilience has been defined as being based on three pillars: resistance (the ability to lower impacts), recovery (the ability to bounce back), and adaptive capacity (the ability to learn and improve). These resilience pillars are important both before and after the occurrence of extreme weather events. Extreme weather insurance can influence these pillars of resilience depending on how particular insurance mechanisms are structured. We explore how the lessons learnt from the current best insurance practices can improve resilience to extreme weather events. We employ an extensive inventory of private property and agricultural crop insurance mechanisms to conduct a multi-criteria analysis of insurance market outcomes. We draw conclusions regarding the patterns in the best practice from six European countries to increase resilience. We suggest that requirements to buy a bundle extreme weather event insurance with general insurance packages are strengthened and supported with structures to financing losses through public-private partnerships. Moreover, support for low income households through income vouchers could be provided. Similarly, for the agricultural sector we propose moving towards comprehensive crop yield insurance linked to general agricultural subsidies. In both cases a nationally representative body can coordinate the various stakeholders into acting in concert.

description: Several different New Zealand economic models produce measures of rural economic activity that have greenhouse gas implications. For climate change analysis, models need to translate economic activity into greenhouse gas emissions. This document estimates functions and creates projections for land-use related greenhouse gas emissions per unit of economic activity that are simple; are based on readily available data and strong science; are consistent with the national inventory in 2002; evolve so that implied net emissions approximately match past inventory totals (1990–2002); and can be linked easily to a variety of models so they can be used in simulations. We estimate dynamic greenhouse gas emission functions for five land uses: dairy, sheep, beef, plantation forestry, and indigenous forests; and for three greenhouse gases: methane, nitrous oxide, and carbon dioxide. We use an approach based on the consensus reached at the November 2004 “Land Use, Climate Change and Kyoto: Human dimensions research” project research workshop. These functions will allow different researchers who are studying activity levels in the rural sector to draw on a consistent set of emission functions when considering the greenhouse gas implications of their model results. All these data are available at www.motu.org.nz/dataset.htm so other researchers can easily apply these functions.

description: It is argued that an electronically charged dilaton black hole can support a long range field of a Nielsen-Olesen string. Combining both numerical and perturbative techniques we examine the properties of an Abelian-Higgs vortex in the presence of the black hole under consideration. Allowing the black hole to approach extremality we found that all fields of the vortex are expelled from the extreme black hole. In the thin string limit we obtained the metric of a conical electrically charged dilaton black hole. The effect of the vortex can be measured from infinity justifying its characterization as black hole hair.

description: Type one diabetes mellitus is a chronic disease that results in the dysregulation of blood glucose levels. Current therapeutic approaches for patients with type one diabetes include continuous monitoring of blood glucose levels and self-administration of exogenous insulin. Islet or β-cell transplantation allows for insulin-independency and doesn’t pose the risk of the patients under- or over-medicating themselves. With increasing studies understanding the human pancreas during development and as an adult, the field of islet transplantation has progressed greatly over the last decades with specific interest in the areas of enhancing donor islet survival, improving stem cell-derived β-cell differentiation protocols, and protecting islet transplants from the immune system. In this thesis, the different aspects of islet transplantation and cell monitoring modalities were addressed from a bioengineering perspective to improve transplant outcomes. We investigated the use of lentiviral forward programming protocols to improve the efficiency of β-cell differentiation, emphasizing the importance of recapitulating the temporal expression of the mature β-cell markers as in development. Further, to support the β-cells post-transplantation, we moved towards re-establishment of the human adult pancreatic environment using extracellular matrix proteins strongly associated with insulin-producing cells within the islets of Langerhans, decorin and nidogen-1. Interestingly, supplementation of these recombinantly-produced proteins to our immortalized β-cell line pseudo-islet model and isolated human donor islets improved glucose-responsiveness, and protected them under hypoxic conditions as experienced in a post-transplantation environment. Furthermore, decorin was observed to reduce the expression of fibrotic ECM proteins, suggesting a role in preventing fibrotic capsule formation surrounding the transplant which would otherwise render it ineffective. We also demonstrated the use of FLIM to non-invasively monitor the metabolic response of the β-cells to glucose stimulation and changes in oxygen levels in its environment in real-time. Altogether, this thesis highlights the importance of recapitulating the signals and cues β-cells experience in vivo to best improve islet transplantation outcomes.

description: The recent rapid advancement in the ability to create and manipulate superconducting qubit systems has created an exciting opportunity to construct quantum materials from the ground up, artificial atom by atom. This thesis will explore the creation of a new architecture of quantum simulation in which we use the circuit quantum electrodynamics toolbox to build quantum topological materials that so far have proven difficult to understand with theory, simulate with computational methods, and realize/measure with other quantum systems. Specifically we design a two-dimensional material in which microwave photons living in a superconducting 3D microwave cavity lattice interact strongly with a time-reversal symmetry breaking magnetic field and with each other. This is the first photonic topological lattice platform compatible with strong interactions. The combination of these interactions will enable the study of fractional quantum Hall systems, where fractionally charged particles called anyons are theorized to exist. This thesis describes how to engineer a tunable, low loss microwave lattice, create a magnetic field for chargeless photons using ferrite crystals, and generate inter-particle interactions using Josephson junction transmon qubits.

description: ALMA observations of CO(1-0) and CO(2-1) emissions of the circumstellar envelope of EP Aqr, an oxygen-rich AGB star, are reported. A thorough analysis of their properties is presented using an original method based on the separation of the data-cube into a low velocity component associated with an equatorial outflow and a faster component associated with a bipolar outflow. A number of important and new results are obtained concerning the distribution in space of the effective emissivity, the temperature, the density and the flux of matter. A mass loss rate of (1.6$\pm$0.4)10$^{-7}$ solar masses per year is measured. The main parameters defining the morphology and kinematics of the envelope are evaluated and uncertainties inherent to de-projection are critically discussed. Detailed properties of the equatorial region of the envelope are presented including a measurement of the line width and a precise description of the observed inhomogeneity of both morphology and kinematics. In particular, in addition to the presence of a previously observed spiral enhancement of the morphology at very small Doppler velocities, a similarly significant but uncorrelated circular enhancement of the expansion velocity is revealed, both close to the limit of sensitivity. The results of the analysis place significant constraints on the parameters of models proposing descriptions of the mass loss mechanism, but cannot choose among them with confidence.

Based on a Fokker-Planck description associated with the dynamics we establish that the drift and the diffusion coefficients can be related through a set of stochastic parameters which characterize the steady state of the dynamical system in a way similar to fluctuation-dissipation relation in non-equilibrium statistical mechanics. The proposed relationship is verified by numerical experiments on a driven double well system.

description: Today's era is characterized as the "digital transformation era". Digital processes and information systems are used in every aspect of social and business activity. The use of information technology over the internet is so extensive that we interact with it daily without even recognizing it. The technological advances can offer a plethora of improvements for the supply chain processes, especially in the field of distribution planning and execution. The scope of this paper is to present the technological content of an advanced routing and scheduling system for transportation and delivery of goods. The system focuses on the routing and scheduling problem in urban areas, as city logistics have become a complex environment for companies to deliver their goods. The presented system deals with both static and dynamic routing and scheduling problems. More specifically, the system can create initial routing plans based on orders, available vehicles, time windows, and traffic forecasting data. Afterwards, during the execution of the plans, the system can monitor the fleet, detect deviations from the original plans, and finally, perform rerouting operations when needed. After a brief presentation of the system's modules and functionality, the paper describes thoroughly the technologies used to develop the system. The technological elements of the system are integrated into a cloud environment offering a system that is easy to maintain and can effectively support logistics companies' distribution activities. The system is provided as a Software as a Service with data being maintained on a central host and processed on the cloud. Therefore, logistics companies that decide to implement it can achieve faster, more accurate and more cost-efficient distribution activities while ensuring better customer service.

Jets, winds and bursts from coalescing neutron stars

Year: 2002
Subjects: subject: Astrophysics (astro-ph)

description: Recent high-resolution calculations of neutron star coalescences are used to investigate whether nu bar{nu} annihilation can provide sufficient energy to power gamma-ray bursts, especially those belonging to the short duration category. Late time slices of the simulations, where the neutrino emission has reached a maximum, stationary level are analyzed to address this question. We find that nu bar{nu} annihilation can provide the necessary driving stresses that lead to relativistic jet expansion. Maximum Lorentz factors of the order of 15 are found along the binary rotation axis, but larger values are expected to arise from higher numerical resolution. Yet the accompanying neutrino-driven wind must be absent from the axis when the burst occurs or prohibitive baryon loading may occur. We argue that even under the most favorable conditions, nu bar{nu} annihilation is unlikely to power a burst in excess of ~ 10^{48} erg. Unless the emission is beamed into less than one percent of the solid angle, which we argue is improbable if it is collimated by gas pressure, this may fail to satisfy the apparent isotropic energies inferred at cosmological distances. This mechanism may nonetheless drive a precursor fireball, thereby evacuating a cavity into which a later magnetic driven jet could expand. A large range of time delays between the merger and the black hole formation are to be expected. If the magnetic driven jet occurs after the black hole has formed, a time span as long as weeks could pass between the neutrino powered precursor and the magnetic driven GRB.

description: This paper provides an overview of key issues involved in the choice among marketbased instruments for climate change policy. Specifically, it examines the potential net benefits from shifting to a permit system for emission reduction, and the preconditions necessary for this change. It also draws out the implications of New Zealand’s specific circumstances and current climate policies for future policy development.

description: We present a composite fermion theory of tunneling into the edge of a compressible quantum Hall system. The tunneling conductance is non-ohmic, due to slow relaxation of electromagnetic and Chern-Simons field disturbances caused by the tunneling electron. Universal results are obtained in the limit of a large number of channels involved in the relaxation. The tunneling exponent is found to be a continuous function of the filling factor nu, with a a slope that is discontinuous at nu=1/2 in the limit of vanishing bulk resistivity rho_xx. When nu corresponds to a principal fractional quantized Hall state, our results agree with the chiral Luttinger liquid theories of Wen, and Kane, Fisher and Polchinski.

description: We have recently shown that the baryonic Tully-Fisher and Faber-Jackson relations imply that the gravitational "constant" $G$ in the force law varies with acceleration $a$ as $G\propto 1/a$ and vice versa. These results prompt us to reconsider every facet of Newtonian dynamics. Here we show that the integral form of Gauss's law in spherical symmetry remains valid in $G(a)$ gravity, but the differential form depends on the precise distribution of $G(a)M(r)$, where $r$ is the distance from the origin and $M(r)$ is the mass distribution. We derive the differential form of Gauss's law in spherical symmetry, thus the source for Poisson's equation as well. Modified Newtonian dynamics (MOND) and weak-field Weyl gravity are asymptotic limits of $G(a)$ gravity at low and high accelerations, respectively. In these limits, we derive telling approximations to the source in spherical symmetry. It turns out that the source has a strong dependence on surface density $M/r^2$ everywhere in $a$-space except in the deep Newton-Weyl regime of very high accelerations.

description: We describe the structure of the moduli space of $σ$-model couplings for the worldsheet description of a system of $N$ D-particles, in the case that the couplings are represented by a pair of logarithmic recoil operators. We derive expressions for the canonical momenta conjugate to the D-particle couplings and the Zamolodchikov metric to the first few orders in $σ$-model perturbation theory. We show, using only very general properties of the operator product expansion in logarithmic conformal field theories, that the canonical dynamics on moduli space agree with the predictions of the non-abelian generalization of the Born-Infeld effective action for D-particles with a symmetrized trace structure. We demonstrate that the Zamolodchikov metric naturally encodes the short-distance structure of spacetime, and from this we derive uncertainty relations for the D-particle coordinates directly from the quantum string theory. We show that the moduli space geometry naturally leads to new forms of spacetime indeterminancies involving only spatial coordinates of target space and illustrate the manner in which the open string interactions between D-particles lead to a spacetime quantization. We also derive appropriate non-abelian generalizations of the string-modified Heisenberg uncertainty relations and the space--time uncertainty principle. The non-abelian uncertainties exhibit decoherence effects suggesting the interplay of quantum gravity in multiple D-particle dynamics.

description: The protection against tuberculosis induced by the Bacille Calmette Guérin (BCG) vaccine is unpredictable. In our previous study, altered DNA methylation pattern in peripheral blood mononuclear cells (PBMCs) in response to BCG was observed in a subgroup of individuals, whose macrophages killed mycobacteria effectively (‘responders’). These macrophages also showed production of Interleukin-1β (IL-1β) in response to mycobacterial stimuli before vaccination. Here, we hypothesized that the propensity to respond to the BCG vaccine is reflected in the DNA methylome. We mapped the differentially methylated genes (DMGs) in PBMCs isolated from responders/non-responders at the time point before vaccination aiming to identify possible predictors of BCG responsiveness. We identified 43 DMGs and subsequent bioinformatic analyses showed that these were enriched for actin-modulating pathways, predicting differences in phagocytosis. This could be validated by experiments showing that phagocytosis of mycobacteria, which is an event preceding mycobacteria-induced IL-1β production, was strongly correlated with the DMG pattern.

description: The large $N$ expansion of giant graviton correlators is considered. Giant gravitons are described using operators with a bare dimension of order $N$. In this case the usual $1/N$ expansion is not applicable and there are contributions to the correlator that are non-perturbative in character. By writing the (square of the) correlators in terms of the hypergeometric function ${}_2F_1(a,b;c;1)$, we are able to rephrase the $1/N$ expansion of the correlator as a semi-classical expansion for a Schrödinger equation. In this way we are able to argue that the $1/N$ expansion of the correlator is Borel summable and that it exhibits a parametric Stokes phenomenon as the angular momentum of the giant graviton is varied.
