description: The recent development of LA-ICP-MS/MS has revolutionized Rb-Sr mica dating allowing to obtain isotopic data within their microstructural context. While effective for old and felsic materials, this method presents challenges for young metamafic and metasomatic rocks due to limited radiogenic ingrowth associated with low Rb/Sr and young ages. We quantitatively address these limitations by combining laser ablation ICP-MS/MS and MC-ICP-MS data for coexisiting white mica and epidote, respectively, for 10 Cenozoic metamorphic rocks from Syros Island (Greece). White mica analyses from metamafic and metasomatic rocks yield limited Rb/Sr spread, which typically does not exceed one order of magnitude (⁸⁷Rb/⁸⁶Sr = 14 to 231 for the combined dataset), and low radiogenic ⁸⁷Sr/⁸⁶Sr (generally <0.8), resulting in high age uncertainties of typically 10 to 50 % RSE, and thus hampering robust geological interpretations. Epidote ⁸⁷Sr/⁸⁶Sr values range between ~0.705 and 0.708. The former (lower-end) is expected for typical, unaltered metamafic materials, whereas the latter is interpreted to reflect fluid-rock interaction along shear zones, with fluids derived from or having interacted with  more radiogenic lithologies. These atypical values suggest that a commonly assumed value of 0.703 for mafic rocks may not always be representative. Anchoring white mica Rb/Sr to epidote ⁸⁷Sr/⁸⁶Sr data improves age accuracy and precision substantially (e.g., 29 ± 17 Ma vs 47.2 ± 4.4 Ma for sample SYGR36). The new ages obtained in this study are consistent with multiple events previously recorded in Syros and the Cyclades blueschists unit including: i) metasomatism at near-peak to epidote blueschist-facies during early exhumation (47.2 ± 3.8 Ma to 41.1 ± 3.1); ii) a late stage of high-pressure exhumation and metasomatism transitioning to blueschist-greenschist-facies (20.8 ± 3.1 Ma to 19.8 ± 5.2 Ma). Anchored white mica Rb/Sr dates thus allow us to discriminate events of fluid-rock interactions and metasomatism associated with shear zone deformation at the subduction interface.

Absence of trapped surfaces and singularities in cylindrical collapse

description: The gravitational collapse of an infinite cylindrical thin shell of generic matter in an otherwise empty spacetime is considered. We show that geometries admitting two hypersurface orthogonal Killing vectors cannot contain trapped surfaces in the vacuum portion of spacetime causally available to geodesic timelike observers. At asymptotic future null infinity, however, congruences of outgoing radial null geodesics become marginally trapped, due to convergence induced by shear caused by the interaction of a transverse wave component with the geodesics. The matter shell itself is shown to be always free of trapped surfaces, for this class of geometries. Finally, two simplified matter models are analytically examined. For one model, the weak energy condition is shown to be a necessary condition for collapse to halt; for the second case, it is a sufficient condition for collapse to be able to halt.

Reasoning about Interior Mutability in Rust using Library-Defined Capabilities

Publisher: name: ETH Zurich

description: Existing automated verification techniques for safe Rust code rely on the strong type-system properties to reason about programs, especially to deduce which memory locations do not change (i.e., are framed) across function calls. However, these type guarantees do not hold in the presence of interior mutability (e.g., when interacting with any concurrent data structure). As a consequence, existing verification techniques for safe code such as Prusti and Creusot are either unsound or fundamentally incomplete if applied to this setting. In this work, we present the first technique capable of automatically verifying safe clients of existing interiorly mutable types. At the core of our approach, we identify a novel notion of implicit capabilities: library-defined properties that cannot be expressed using Rust's types. We propose new annotations to specify these capabilities and a first-order logic encoding suitable for program verification. We have implemented our technique in a verifier called Mendel and used it to prove absence of panics in Rust programs that make use of popular standard-library types with interior mutability, including Rc, Arc, Cell, RefCell, AtomicI32, Mutex and RwLock. Our evaluation shows that these library annotations are useful for verifying usages of real-world libraries, and powerful enough to require zero client-side annotations in many of the verified programs.

We review the influence of the finite size of the particles and of their energy level spectrum on the diffraction pattern. In turn, we demonstrate how experimental diffraction measurements allow to determine these quantities of weakly bound molecules by considering the diffraction of the dimer and trimer of helium, and the deuterium molecule dimer.

description: Using archival data from the Chandra X-ray telescope, we have measured the spatial extent of the hot interstellar gas in a sample of 49 nearby interacting galaxy pairs, mergers, and merger remnants. For systems with SFR > 1 M(sun)/yr, the volume and mass of hot gas are strongly and linearly correlated with the star formation rate (SFR). This supports the idea that stellar/supernovae feedback dominates the production of hot gas in these galaxies. We compared the mass of X-ray-emitting hot gas Mx(gas) with the molecular and atomic hydrogen interstellar gas masses in these galaxies (M(H2) and M(HI), respectively), using published carbon monoxide and 21 cm HI measurements. Systems with higher SFRs have larger Mx(gas)/(M(H2) + M(HI)) ratios on average, in agreement with recent numerical simulations of star formation and feedback in merging galaxies. The Mx(gas)/(M(H2) + M(HI)) ratio also increases with dust temperature on average. The ratio Mx(gas)/SFR is anti-correlated with the IRAS 60 micron to 100 micron flux ratio and with the Spitzer 3.6 micron to 24 micron. These trends may be due to variations in the spatial density of young stars, the stellar age, the ratio of young to old stars, the initial mass function, and/or the efficiency of stellar feedback. Galaxies with low SFR (<1 M(sun)/yr) and high K band luminosities may have an excess of hot gas relative to the relation for higher SFR galaxies, while galaxies with low K band luminosities (and therefore low stellar masses) may have a deficiency in hot gas, but our sample is not large enough for strong statistical significance.

description: Causality has been the issue of philosophic debate since Hippocrates. It is used in formal verification and testing, e.g., to explain counterexamples or construct fault trees. Recent work defines actual causation in terms of Pearl's causality framework, but most definitions brought forward so far struggle with examples where one event preempts another one. A key point to capturing such examples in the context of programs or distributed systems is a sound treatment of control flow. We discuss how causal models should incorporate control flow and discover that much of what Pearl/Halpern's notion of contingencies tries to capture is captured better by an explicit modelling of the control flow in terms of structural equations and an arguably simpler definition. Inspired by causality notions in the security domain, we bring forward a definition of causality that takes these control-variables into account. This definition provides a clear picture of the interaction between control flow and causality and captures these notoriously difficult preemption examples without secondary concepts. We give convincing results on a benchmark of 34 examples from the literature.

description: Numerical linear algebra anhd combinational optomization are vast subjects; as is their interaction. In virtually all cases there should be a notion of sparsity for a combinatorial problem to arise. Sparse matrices therefore form the basis of the interaction of these seemingly disparate subjects. As the core of many of today's numerical linear algebra computations consists of the solution of sparse linear system by direct or iterative methods, we survey some cominatorial problems, ideas, and algorithms relating to these computations. On the direct methods side, we discuss issues such as matrix ordering; bipartite matching and matrix scaling for better pivoting; task assignment and scheduling for parallel multifrontal solvers. On the iterative side, we discuss the preconditioning techniques including incomplete factorization preconditioners, support graph preconditioners, and algebraic multigrid. In a seperate part, we discuss the block trianglar form of sparse matrices.

description: The design of structure-preserving integrators is dealt with in the framework of a discrete model problem for large-strain thermo-viscoelasticity. The evolution equations pertaining to the model problem are cast in the framework of GENERIC. The GENERIC formalism provides an ideal foundation for the design of energy-momentum-entropy (EME) consistent time-stepping schemes. An analogous approach can be applied to the full continuum model for large-strain thermo-viscoelasticity.

description: The Home Meal Replacement (HMR) sector has been growing rapidly in the food industry. Due to the conveniences that the HMR product offers, the target consumers are generally busy workers and/or individuals who live alone. This study aims to investigate factors that affect the purchasing of HMR products and to formulate strategies for future HMR product sales. This study examines the effect of five independent variables: dine-out frequency, dine-out costs, and the employment status of housewives, involvement of meal preparation, and the role of overload on HMR purchase behavior. The study also examines what influences the purchasing of HMR products through different kinds of lifestyles. Surveys were conducted with a panel of housewives from major metropolitan areas in South Korea and configured by clusters according to different lifestyles. The panel of housewives was divided into four groups based on Food Related Lifestyles: Price Insensitive Group, Pride in Cooking Group, Indifference to Health Group and Against Eating Out Group. The results indicate that HMR sales target segments are consumers who tend to dine-out more and desire a low involvement in meal preparation than consumers who are busy and have less time to cook at home.

description: We study the geometrical characteristic of quasi-static fractures in disordered media, using iterated conformal maps to determine the evolution of the fracture pattern. This method allows an efficient and accurate solution of the Lamé equations without resorting to lattice models. Typical fracture patterns exhibit increased ramification due to the increase of the stress at the tips. We find the roughness exponent of the experimentally relevant backbone of the fracture pattern; it crosses over from about 0.5 for small scales to about 0.75 for large scales, in excellent agreement with experiments. We propose that this cross-over reflects the increased ramification of the fracture pattern.

description: We use the Wide Field Camera 3 on the {\sl Hubble Space Telescope} to spectrophotometrically monitor the young L7.5 companion HD~203030B. Our time series reveal photometric variability at 1.27\,$μ$m and 1.39\,$μ$m on time scales compatible with rotation. We find a rotation period of $7.5^{+0.6}_{-0.5}$ h: comparable to those observed in other brown dwarfs and planetary-mass companions younger than 300 Myr. We measure variability amplitudes of $1.1\pm0.3\%$ (1.27\,$μ$m) and $1.7\pm0.4\%$ (1.39\,$μ$m), and a phase lag of 56$^\circ\pm$28$^\circ$ between the two light curves. We attribute the difference in photometric amplitudes and phases to a patchy cloud layer that is sinking below the level where water vapor becomes opaque. HD 203030B and the few other known variable young late-L dwarfs are unlike warmer (earlier-type and/or older) L dwarfs, for which variability is much less wavelength-dependent across the 1.1--1.7$μ$m region. We further suggest that a sinking of the top-most cloud deck below the level where water or carbon monoxide gas become opaque may also explain the often enhanced variability amplitudes of even earlier-type low-gravity L dwarfs. Because these condensate and gas opacity levels are already well-differentiated in T dwarfs, we do not expect the same variability amplitude enhancement in young vs.\ old T dwarfs.

description: Further Education (FE) institutions are often overlooked when it comes to data management and preservation. They’re not research intensive, they tend not to be collection oriented, and there’s little tradition of institutional legacy management. However, they do have a major preservation problem, a ticking time bomb that is going to erupt in the not too distant future. What’s more, this is a problem that appears to have been overlooked my much of the Data and Preservation establishment. At the core of this? Electronic Records Management. FE institutions need to keep a LOT of data… And they need to keep it for a long time. That in itself would be a problem. However, it is exacerbated by the systems and infrastructure in use in the sector. Historically FE systems have evolved organically. As statutory requirements have been added, so systems have been procured to provide immediate, un-integrated, short term solutions—point solutions. This on its own is bad enough, but it has been exacerbated through a recent flurry of mergers and acquisitions. Most system suppliers appear to have not given much thought (if any) to the possibility of two (or more) Student Information Management System(s) from different institutions being merged. Pain points experienced by FE include: Multiple systems Obsolescence Little or no interconnection between systems Little or no data back-up or export facilities Mergers have caused a data export/import/merge nightmare Exponentially increasing storage requirements Arduous retention obligations Ambiguous data standards (where they exist) In this lightning talk I intend to explore the landscape of FE data management and preservation—highlighting the pain points, exposing the areas of concern—and present an action plan for addressing those concerns.

Increasing $I_s$ causes lowering and broadening of (1) coherence peaks of s-wave S, and d-wave S at (100) contact, (2) midgap-states-induced zero-bias conductance peak for d-wave S at (110) contact, and (3) Andreev-reflection-induced enhancement of $G$ within the gap near the metallic-contact limit. Novel features found include a current-induced central peak and a three-humped structure at intermediate barrier strength, etc.

description: This is a summary of a course given at the Fourth Mexican School on Gravitation and Mathematical Physics on some aspects of PBB cosmology. After introductory remarks the lectures concentrate on some amusing consequences derived from the symmetries of the string theory with respect to such classical concepts as isotropy and homogeneity. The extra dimensions and the symmetries of the M theory are further applied to show that the classical singularities might be just physically irrelevant. In the final lecture a model universe is "produced" from "almost nothing" and it is argued that initial plane waves are thermodynamically natural state for the universe to emerge from.

description: Built on our observation that entangling surfaces of the boundary field theory are great co-dimension one spheres in the context of DS/dS correspondence, we study some information theoretic quantities of the field theory dual intensively using holographic proposals. We will focus on entanglement entropy (EE), entanglement of purification (EoP) and complexity. Several fundamental observations and analysis are provided. For EE, we focus on its scaling behavior, which indicates the nature of the relevant degrees of freedom. Moreover, we find that EE provides us with important information of the energy spectrum in pure dS and it also leads us to the speculation that the field theory dual is chaotic or non-integrable. For EoP, an interesting phenomenon we call "Entanglement of Purification Jump" is observed according to which we propose two puzzles regarding EoP and EE in the context of dS holography. For complexity, we find that the Complexity=Volume proposal does not provide a well-defined way to compute complexity for pure dS. However, it does provide a well-defined way to compute complexity in the $T\bar{T}+Λ_{2}$ deformed case. At the end, we will use the surface/state correspondence to resolve all the puzzles and hence reach a consistent information theoretic picture of dS holography. Moreover, we will provide evidence for our former proposal that the $T\bar{T}+\cdots$ deformations are operating quantum circuits and study the non-locality of the field theory algebra suggested by the surface/state correspondence.

Gravitational Radiation Damping and the Three-Body Problem

description: A model of three-body motion is developed which includes the effects of gravitational radiation reaction. The radiation reaction due to the emission of gravitational waves is the only post-Newtonian effect that is included here. For simplicity, all of the motion is taken to be planar. Two of the masses are viewed as a binary system and the third mass, whose motion will be a fixed orbit around the center-of-mass of the binary system, is viewed as a perturbation. This model aims to describe the motion of a relativistic binary pulsar that is perturbed by a third mass. Numerical integration of this simplified model reveals that given the right initial conditions and parameters one can see resonances. These (m,n) resonances are defined by the resonance condition, $mω=2nΩ$, where $m$ and $n$ are relatively prime integers and $ω$ and $Ω$ are the angular frequencies of the binary orbit and third mass orbit, respectively. The resonance condition consequently fixes a value for the semimajor axis of the binary orbit for the duration of the resonance; therefore, the binary energy remains constant on the average while its angular momentum changes during the resonance.

description: We evaluate the effects of a randomly administered educational game on index insurance conducted with 400 households in Ethiopia in the 2010 growing season. Our game teaches farmers about the benefits and limitations of index insurance. All village members were then offered the choice to purchase real index insurance, designed with the input of local communities. We find that financial education, in the form of an experimental game, has a positive and significant effect on take-up for a real index insurance product. These effects are driven by cash purchasers, as labor purchasers' demand exceeded the quota for total allowable labor purchases. Cash purchasers in the game, while more likely to purchase insurance, purchase less coverage than labor purchasers, and even less if exposed to the educational game. As a result, the game had a significant and positive impact on insurance take-up, but an overall negative effect on the amount of insurance purchased, driven by the relatively larger increase in cash purchasers. Financial education is effective at increasing overall take-up, but purchasers who are cash constrained and educated on index insurance purchase less than those similar cash purchasers are not educated on these matters.

description: The formation and dynamics of a wide variety of binary two-dimensional ordered structures and superlattices are investigated through a phase field crystal model with sublattice ordering. Various types of binary ordered phases, the phase diagrams, and the grain growth dynamics and structural transformation processes, including the emergence of topological defects, are examined. The results are compared to the ordering and assembly of two-component colloidal systems. Two factors governing the binary phase ordering are identified, the coupling and competition between the length scales of two sublattices and the selection of average particle densities of two components. The control and variation of these two factors lead to the prediction of various complex binary ordered patterns, with different types of sublattice ordering for integer vs. noninteger ratios of sublattice length scales. These findings will enable further systematic studies of complex ordering and assembly processes of binary systems particularly binary colloidal crystals.

description: We present a recent study of light charged Higgs boson ($H^-$) production at the Large Hadron electron Collider (LHeC). We study the charged current production process $e^- p \to ν_e q H^-$, taking in account the decay channels $H^- \to b\bar{c}$ and $H^-\to τ\barν_τ$. We analyse the process in the framework of the 2-Higgs Doublet Model Type-III (2HDM-III), assuming a four-zero texture in the Yukawa matrices and a general Higgs potential. We consider a variety of both reducible and irreducible backgrounds for the signals of the $H^-$ state. We show that the detection of a light charged Higgs boson is feasible, assuming for the LHeC standard energy and luminosity conditions.

Universal finite size scaling around tricriticality between topologically ordered, SPT, and trivial phases

description: A quantum tricritical point is shown to exists in coupled time-reversal symmetry (TRS) broken Majorana chains. The tricriticality separates topologically ordered, symmetry protected topological (SPT), and trivial phases of the system. Here we demonstrate that the breaking of the TRS manifests itself in an emergence of a new dimensionless scale, $g = α(ξ) B \sqrt{N}$, where $N$ is the system size, $B$ is a generic TRS breaking field, and $α(ξ)$, with $α(0)\equiv 1$, is a model-dependent function of the localization length, $ξ$, of boundary Majorana zero modes at the tricriticality. This scale determines the scaling of the finite size corrections around the tricriticality, which are shown to be {\it universal}, and independent of the nature of the breaking of the TRS. We show that the single variable scaling function, $f(w)$, $w\propto m N$, where $m$ is the excitation gap, that defines finite-size corrections to the ground state energy of the system around topological phase transition at $B=0$, becomes double-scaling, $f=f(w,g)$, at finite $B$. We realize TRS breaking through three different methods with completely different lattice details and find the same universal behavior of $f(w,g)$. In the critical regime, $m=0$, the function $f(0,g)$ is nonmonotonic, and reproduces the Ising conformal field theory scaling only in limits $g=0$ and $g\rightarrow \infty$. The obtained result sets a scale of $N \gg 1/(αB)^2$ for the system to reach the thermodynamic limit in the presence of the TRS breaking. We derive the effective low-energy theory describing the tricriticality and analytically find the asymptotic behavior of the finite-size scaling function. Our results show that the boundary entropy around the tricriticality is also a universal function of $g$ at $m=0$.
