--- _id: '1732' abstract: - lang: eng text: We consider partially observable Markov decision processes (POMDPs), that are a standard framework for robotics applications to model uncertainties present in the real world, with temporal logic specifications. All temporal logic specifications in linear-time temporal logic (LTL) can be expressed as parity objectives. We study the qualitative analysis problem for POMDPs with parity objectives that asks whether there is a controller (policy) to ensure that the objective holds with probability 1 (almost-surely). While the qualitative analysis of POMDPs with parity objectives is undecidable, recent results show that when restricted to finite-memory policies the problem is EXPTIME-complete. While the problem is intractable in theory, we present a practical approach to solve the qualitative analysis problem. We designed several heuristics to deal with the exponential complexity, and have used our implementation on a number of well-known POMDP examples for robotics applications. Our results provide the first practical approach to solve the qualitative analysis of robot motion planning with LTL properties in the presence of uncertainty. arxiv: 1 author: - first_name: Krishnendu full_name: Chatterjee, Krishnendu id: 2E5DCA20-F248-11E8-B48F-1D18A9856A87 last_name: Chatterjee orcid: 0000-0002-4561-241X - first_name: Martin full_name: Chmelik, Martin id: 3624234E-F248-11E8-B48F-1D18A9856A87 last_name: Chmelik - first_name: Raghav full_name: Gupta, Raghav last_name: Gupta - first_name: Ayush full_name: Kanodia, Ayush last_name: Kanodia citation: ama: 'Chatterjee K, Chmelik M, Gupta R, Kanodia A.

While significant progress has occurred over the last two decades, no single survey currently exists that discusses the similarities, differences, and practical considerations of the available appearance capture techniques as applied to human faces. A central difficulty of facial appearance capture is the way light interacts with skin-which has a complex multi-layered structure-and the interactions that occur below the skin surface can, by definition, only be observed indirectly. In this report, we distinguish between two broad strategies for dealing with this complexity. "Image-based methods" try to exhaustively capture the exact face appearance under different lighting and viewing conditions, and then render the face through weighted image combinations. "Parametric methods" instead fit the captured reflectance data to some parametric appearance model used during rendering, allowing for a more lightweight and flexible representation but at the cost of potentially increased rendering complexity or inexact reproduction. The goal of this report is to provide an overview that can guide practitioners and researchers in assessing the tradeoffs between current approaches and identifying directions for future advances in facial appearance capture. article_processing_charge: No author: - first_name: Oliver full_name: Klehm, Oliver last_name: Klehm - first_name: Fabrice full_name: Rousselle, Fabrice last_name: Rousselle - first_name: Marios full_name: Papas, Marios last_name: Papas - first_name: Derek full_name: Bradley, Derek last_name: Bradley - first_name: Christophe full_name: Hery, Christophe last_name: Hery - first_name: Bernd full_name: Bickel, Bernd id: 49876194-F248-11E8-B48F-1D18A9856A87 last_name: Bickel orcid: 0000-0001-6511-9385 - first_name: Wojciech full_name: Jarosz, Wojciech last_name: Jarosz - first_name: Thabo full_name: Beeler, Thabo last_name: Beeler citation: ama: Klehm O, Rousselle F, Papas M, et al.

We first devise a straightforward dimension reduction technique that dramatically reduces the cost of solving the pressure projection. Next, we introduce a novel change of basis that satisfies free-surface boundary conditions exactly, regardless of the accuracy of the pressure solve. When combined, these ideas greatly reduce the computational complexity of the pressure solve without compromising free surface boundary conditions at the highest level of detail. Our techniques are easy to parallelize, and they effectively eliminate the computational bottleneck for large liquid simulations. acknowledgement: The first author was supported by a JSPS Postdoctoral Fellowship for Research Abroad article_processing_charge: No author: - first_name: Ryoichi full_name: Ando, Ryoichi last_name: Ando - first_name: Nils full_name: Thürey, Nils last_name: Thürey - first_name: Christopher J full_name: Wojtan, Christopher J id: 3C61F1D2-F248-11E8-B48F-1D18A9856A87 last_name: Wojtan orcid: 0000-0001-6646-5546 citation: ama: Ando R, Thürey N, Wojtan C.

Here, we consider the implications of a 3–8 times shorter orbital period, suggested by hydrodynamical simulations of circumbinary discs (CBDs) with nearly equal-mass SMBHBs (q ≡ M2/M1 ≳ 0.3). With the corresponding 2–4 times tighter binary separation, PG 1302 would be undergoing gravitational wave dominated inspiral, and serve as a proof that the BHs can be fuelled and produce bright emission even in this late stage of the merger. The expected fraction of binaries with the shorter tbin, among bright quasars, would be reduced by one to two orders of magnitude, compared to the 5.2 yr period, in better agreement with the rarity of candidates reported by Graham et al. Finally, shorter periods would imply higher binary speeds, possibly imprinting periodicity on the light curves from relativistic beaming, as well as measurable relativistic effects on the Fe K α line. The CBD model predicts additional periodic variability on time-scales of tbin and ≈0.5tbin, as well as periodic variation of broad line widths and offsets relative to the narrow lines, which are consistent with the observations. Future observations will be able to test these predictions and hence the binary+CBD hypothesis for PG 1302. article_processing_charge: No article_type: original author: - first_name: D.

Hydrodynamical simulations predict multiple periodic components for the variability of SMBHBs, thus raising the possibility that the true period of the binary is different from 5.2 yr. We analyse the periodogram of PG1302 and find no compelling evidence for additional peaks. We also point out that, despite the 5.2 yr peak being significant if a single source is considered, further analysis is required to account for the fact that PG1302 was selected among a large sample of 247 000 quasars. We derive upper limits on any additional periodic modulations in the available data, by modelling the light curve as the sum of stochastic noise and the known 5.2 yr periodic component, and injecting additional sinusoidal signals. We find that, with the current data, we would be able to detect with high significance (false alarm probability <1 per cent) secondary periodic terms, with periods in the range predicted by the simulations, if the amplitude of the variability was at least ∼0.06 mag (compared to 0.14 mag for the main sinusoid). A three-year follow-up monitoring campaign with weekly observations can increase the sensitivity for detecting secondary peaks by ≈50 per cent, and would allow a more robust test of predictions from hydrodynamical simulations. article_processing_charge: No article_type: original author: - first_name: M. full_name: Charisi, M. last_name: Charisi - first_name: I. full_name: Bartos, I. last_name: Bartos - first_name: Zoltán full_name: Haiman, Zoltán id: 7c006e8c-cc0d-11ee-8322-cb904ef76f36 last_name: Haiman - first_name: A.

We assume that the gas has primordial composition and that H2-cooling and prior star-formation in the haloes have been suppressed.

Our main conclusion is that the spin orientation and magnitude is initially well described by tidal torque linear theory, but later on is determined by the merging and accretion history of each halo. We provide evidence that the topology of the merging region, i.e. the number of colliding filaments, gives an accurate prediction for the spin of dark matter and gas: halos at the center of knots will have low spin while those in the center of filaments will have high spin.

Although they cannot be imaged, periodicities in the light curves of quasars have been interpreted as evidence for binaries, most recently in PG~1302-102, with a short rest-frame optical period of 4 years. If the orbital period matches this value, then for the range of estimated black hole masses the components would be separated by 0.007-0.017 pc, implying relativistic orbital speeds. There has been much debate over whether black hole orbits could be smaller than 1 pc. Here we show that the amplitude and the sinusoid-like shape of the variability of PG~1302-102 can be fit by relativistic Doppler boosting of emission from a compact, steadily accreting, unequal-mass binary. We predict that brightness variations in the ultraviolet light curve track those in the optical, but with a 2-3 times larger amplitude. This prediction is relatively insensitive to the details of the emission process, and is consistent with archival UV data. Follow-up UV and optical observations in the next few years can test this prediction and confirm the existence of a binary black hole in the relativistic regime. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Daniel J. full_name: D'Orazio, Daniel J. last_name: D'Orazio - first_name: Zoltán full_name: Haiman, Zoltán id: 7c006e8c-cc0d-11ee-8322-cb904ef76f36 last_name: Haiman - first_name: David full_name: Schiminovich, David last_name: Schiminovich citation: ama: D’Orazio DJ, Haiman Z, Schiminovich D.

Here we show that this low value leaves essentially no room for an early partial reionisation of the intergalactic medium (IGM) by high-redshift Population III (Pop III) stars, expected to have formed in low-mass minihaloes. We perform semi-analytic calculations of reionisation which include the contribution from Pop II stars in atomic cooling haloes, calibrated with high-redshift galaxy observations, and Pop III stars in minihaloes with feedback due to Lyman-Werner (LW) radiation and metal enrichment. We find that without LW feedback or prompt metal enrichment (and assuming a minihalo escape fraction of 0.5) the Pop III star formation efficiency cannot exceed ∼a few×10−4, without violating the constraints set by Planck data. This excludes massive Pop III star formation in typical 106M⊙ minihaloes. Including LW feedback and metal enrichment alleviates this tension, allowing large Pop III stars to form early on before they are quenched by feedback. We find that the total density of Pop III stars formed across cosmic time is ≲104−5 M⊙ Mpc−3 and does not depend strongly on the feedback prescription adopted. Additionally, we perform a simple estimate of the possible impact on reionisation of X-rays produced by accretion onto black hole remnants of Pop III stars. We find that unless the accretion duty cycle is very low (≲0.01), this could lead to an optical depth inconsistent with Planck. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Eli full_name: Visbal, Eli last_name: Visbal - first_name: Zoltán full_name: Haiman, Zoltán id: 7c006e8c-cc0d-11ee-8322-cb904ef76f36 last_name: Haiman - first_name: Greg L. full_name: Bryan, Greg L. last_name: Bryan citation: ama: Visbal E, Haiman Z, Bryan GL.

We use toy models for the distribution of recoil velocities, BH trajectories, and the geometry of obscuring dust tori in galactic centres, to simulate 2.5x10^5 random observations of recoiling quasars. BHs with recoil velocities comparable to the escape velocity from the galactic centre remain bound to the nucleus, and do not fully settle back to the centre of the torus due to dynamical friction in a typical quasar lifetime. We find that |\Delta v| and \Sigma_ {dust} for these BHs are positively correlated. For obscured (\Sigma_{dust}>0) and for partially obscured (0<\Sigma_{dust}<~2.3 g/m^2) quasars with |\Delta v|>=45 km/s, the sample correlation coefficient between log10(|\Delta v|) and \Sigma_{dust} is r_{45} = 0.28+/-0.02 and r_{45} = 0.13+/-0.02, respectively. Allowing for random +/-100 km/s errors in |\Delta v| unrelated to the recoil dilutes the correlation for the partially obscured quasars to r_{45} = 0.026+/-0.004 measured between |\Delta v| and \Sigma_{dust}. A random sample of >~3,500 obscured quasars with |\Delta v|>=45 km/s would allow rejection of the no-correlation hypothesis with 3 sigma significance 95% of the time. Finally, we find that the fraction of obscured quasars, F_{obs}(|\Delta v|), decreases with |\Delta v| from F_{obs}(<10 km/s)>~0.8 to F_{obs}(>10^3 km/s)<~0.4. This predicted trend can be compared to the observed fraction of type II quasars, and can further test combinations of recoil, trajectory, and dust torus models. article_processing_charge: No article_type: original author: - first_name: P. full_name: Raffai, P. last_name: Raffai - first_name: Zoltán full_name: Haiman, Zoltán id: 7c006e8c-cc0d-11ee-8322-cb904ef76f36 last_name: Haiman - first_name: Z. full_name: Frei, Z. last_name: Frei citation: ama: Raffai P, Haiman Z, Frei Z.

In this paper, we suggest that intensity mapping may be a promising method to study Pop III stars. Intensity mapping is a technique proposed to measure large-scale fluctuations of galaxy line emission in three dimensions without resolving individual sources. This technique is well suited for observing many faint galaxies because it can measure their cumulative emission even if they cannot be directly detected. We focus on intensity mapping of He ii recombination lines. These lines are much stronger in Pop III stars than Pop II stars because the harder spectra of Pop III stars are expected to produce many He ii ionizing photons. Measuring the He ii 1640 Å intensity mapping signal, along with the signals from other lines such as Lyα, Hα, and metal lines, could give constraints on the initial mass function (IMF) and star formation rate density of Pop III stars as a function of redshift. To demonstrate the feasibility of these observations, we estimate the strength of the Pop III He ii 1640 Å intensity mapping signal from z = 10–20. We show that at z ≈ 10, the signal could be measured accurately by two different hypothetical future instruments, one which cross-correlates He ii 1640 Å with CO(1–0) line emission from galaxies and the other with 21 cm emission from the intergalactic medium. article_processing_charge: No article_type: original author: - first_name: Eli full_name: Visbal, Eli last_name: Visbal - first_name: Zoltán full_name: Haiman, Zoltán id: 7c006e8c-cc0d-11ee-8322-cb904ef76f36 last_name: Haiman - first_name: Greg L. full_name: Bryan, Greg L. last_name: Bryan citation: ama: Visbal E, Haiman Z, Bryan GL.

We examine constraints on the parameter triplet (Ωm,w,σ8) from non-Gaussian features of the weak lensing convergence field, including a set of moments (up to 4th order) and Minkowski functionals, using publicly available data from the 154deg2 CFHTLenS survey. We utilize a suite of ray--tracing N-body simulations spanning 91 points in (Ωm,w,σ8) parameter space, replicating the galaxy sky positions, redshifts and shape noise in the CFHTLenS catalogs. We then build an emulator that interpolates the simulated descriptors as a function of (Ωm,w,σ8), and use it to compute the likelihood function and parameter constraints. We employ a principal component analysis to reduce dimensionality and to help stabilize the constraints with respect to the number of bins used to construct each statistic. Using the full set of statistics, we find Σ8≡σ8(Ωm/0.27)^0.55=0.75±0.04 (68% C.L.), in agreement with previous values. We find that constraints on the (Ωm,σ8) doublet from the Minkowski functionals suffer a strong bias. However, high-order moments break the (Ωm,σ8) degeneracy and provide a tight constraint on these parameters with no apparent bias. The main contribution comes from quartic moments of derivatives. article_number: '103511' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Andrea full_name: Petri, Andrea last_name: Petri - first_name: Jia full_name: Liu, Jia last_name: Liu - first_name: Zoltán full_name: Haiman, Zoltán id: 7c006e8c-cc0d-11ee-8322-cb904ef76f36 last_name: Haiman - first_name: Morgan full_name: May, Morgan last_name: May - first_name: Lam full_name: Hui, Lam last_name: Hui - first_name: Jan M. full_name: Kratochvil, Jan M. last_name: Kratochvil citation: ama: 'Petri A, Liu J, Haiman Z, May M, Hui L, Kratochvil JM.

Is trait variation influenced by many genes of small effect or by a few genes of major effect? Where is additive genetic variation located in the genome? Do the same loci cause similar phenotypic variation in different populations? Great tits (Parus major) have been studied extensively in long‐term studies across Europe and consequently are considered an ecological ‘model organism’. Recently, genomic resources have been developed for the great tit, including a custom SNP chip and genetic linkage map. In this study, we used a suite of approaches to investigate the genetic architecture of eight quantitative traits in two long‐term study populations of great tits—one in the Netherlands and the other in the United Kingdom. Overall, we found little evidence for the presence of genes of large effects in either population. Instead, traits appeared to be influenced by many genes of small effect, with conservative estimates of the number of contributing loci ranging from 31 to 310. Despite concordance between population‐specific heritabilities, we found no evidence for the presence of loci having similar effects in both populations. While population‐specific genetic architectures are possible, an undetected shared architecture cannot be rejected because of limited power to map loci of small and moderate effects. This study is one of few examples of genetic architecture analysis in replicated wild populations and highlights some of the challenges and limitations researchers will face when attempting similar molecular quantitative genetic studies in free‐living populations. article_processing_charge: No article_type: original author: - first_name: Anna W. full_name: Santure, Anna W. last_name: Santure - first_name: Jocelyn full_name: Poissant, Jocelyn last_name: Poissant - first_name: Isabelle full_name: De Cauwer, Isabelle last_name: De Cauwer - first_name: Kees full_name: van Oers, Kees last_name: van Oers - first_name: Matthew Richard full_name: Robinson, Matthew Richard id: E5D42276-F5DA-11E9-8E24-6303E6697425 last_name: Robinson orcid: 0000-0001-8982-8813 - first_name: John L. full_name: Quinn, John L. last_name: Quinn - first_name: Martien A.

These social effects may play a major role in the evolution of cooperative breeding if social partners differ in the quality of care they provide and if individual carers adjust their effort in relation to that of other carers. When applying social effects models to wild study systems, it is also important to explore sources of individual plasticity that could masquerade as social effects. We studied offspring provisioning rates of parents and helpers in a wild population of long-tailed tits Aegithalos caudatus using a quantitative genetic framework to identify these social effects and partition them into genetic, permanent environment and current environment components. Controlling for other effects, individuals were consistent in their provisioning effort at a given nest, but adjusted their effort based on who was in their social group, indicating the presence of social effects. However, these social effects differed between years and social contexts, indicating a current environment effect, rather than indicating a genetic or permanent environment effect. While this study reveals the importance of examining environmental and genetic sources of social effects, the framework we present is entirely general, enabling a greater understanding of potentially important social effects within any ecological population. article_number: '20150689' article_processing_charge: No article_type: original author: - first_name: Mark James full_name: Adams, Mark James last_name: Adams - first_name: Matthew Richard full_name: Robinson, Matthew Richard id: E5D42276-F5DA-11E9-8E24-6303E6697425 last_name: Robinson orcid: 0000-0001-8982-8813 - first_name: Maria-Elena full_name: Mannarelli, Maria-Elena last_name: Mannarelli - first_name: Ben J. full_name: Hatchwell, Ben J. last_name: Hatchwell citation: ama: 'Adams MJ, Robinson MR, Mannarelli M-E, Hatchwell BJ.

Here we find that many independent loci contribute to population genetic differences in height and body mass index (BMI) in 9,416 individuals across 14 European countries. Using discovery data on over 250,000 individuals and unbiased effect size estimates from 17,500 sibling pairs, we estimate that 24% (95% credible interval (CI) = 9%, 41%) and 8% (95% CI = 4%, 16%) of the captured additive genetic variance for height and BMI, respectively, reflect population genetic differences. Population genetic divergence differed significantly from that in a null model (height, P < 3.94 × 10−8; BMI, P < 5.95 × 10−4), and we find an among-population genetic correlation for tall and slender individuals (r = −0.80, 95% CI = −0.95, −0.60), consistent with correlated selection for both phenotypes. Observed differences in height among populations reflected the predicted genetic means (r = 0.51; P < 0.001), but environmental differences across Europe masked genetic differentiation for BMI (P < 0.58). article_processing_charge: No article_type: original author: - first_name: Matthew Richard full_name: Robinson, Matthew Richard id: E5D42276-F5DA-11E9-8E24-6303E6697425 last_name: Robinson orcid: 0000-0001-8982-8813 - first_name: Gibran full_name: Hemani, Gibran last_name: Hemani - first_name: Carolina full_name: Medina-Gomez, Carolina last_name: Medina-Gomez - first_name: Massimo full_name: Mezzavilla, Massimo last_name: Mezzavilla - first_name: Tonu full_name: Esko, Tonu last_name: Esko - first_name: Konstantin full_name: Shakhbazov, Konstantin last_name: Shakhbazov - first_name: Joseph E full_name: Powell, Joseph E last_name: Powell - first_name: Anna full_name: Vinkhuyzen, Anna last_name: Vinkhuyzen - first_name: Sonja I full_name: Berndt, Sonja I last_name: Berndt - first_name: Stefan full_name: Gustafsson, Stefan last_name: Gustafsson - first_name: Anne E full_name: Justice, Anne E last_name: Justice - first_name: Bratati full_name: Kahali, Bratati last_name: Kahali - first_name: Adam E full_name: Locke, Adam E last_name: Locke - first_name: Tune H full_name: Pers, Tune H last_name: Pers - first_name: Sailaja full_name: Vedantam, Sailaja last_name: Vedantam - first_name: Andrew R full_name: Wood, Andrew R last_name: Wood - first_name: Wouter full_name: van Rheenen, Wouter last_name: van Rheenen - first_name: Ole A full_name: Andreassen, Ole A last_name: Andreassen - first_name: Paolo full_name: Gasparini, Paolo last_name: Gasparini - first_name: Andres full_name: Metspalu, Andres last_name: Metspalu - first_name: Leonard H van den full_name: Berg, Leonard H van den last_name: Berg - first_name: Jan H full_name: Veldink, Jan H last_name: Veldink - first_name: Fernando full_name: Rivadeneira, Fernando last_name: Rivadeneira - first_name: Thomas M full_name: Werge, Thomas M last_name: Werge - first_name: Goncalo R full_name: Abecasis, Goncalo R last_name: Abecasis - first_name: Dorret I full_name: Boomsma, Dorret I last_name: Boomsma - first_name: Daniel I full_name: Chasman, Daniel I last_name: Chasman - first_name: Eco J C full_name: de Geus, Eco J C last_name: de Geus - first_name: Timothy M full_name: Frayling, Timothy M last_name: Frayling - first_name: Joel N full_name: Hirschhorn, Joel N last_name: Hirschhorn - first_name: Jouke Jan full_name: Hottenga, Jouke Jan last_name: Hottenga - first_name: Erik full_name: Ingelsson, Erik last_name: Ingelsson - first_name: Ruth J F full_name: Loos, Ruth J F last_name: Loos - first_name: Patrik K E full_name: Magnusson, Patrik K E last_name: Magnusson - first_name: Nicholas G full_name: Martin, Nicholas G last_name: Martin - first_name: Grant W full_name: Montgomery, Grant W last_name: Montgomery - first_name: Kari E full_name: North, Kari E last_name: North - first_name: Nancy L full_name: Pedersen, Nancy L last_name: Pedersen - first_name: Timothy D full_name: Spector, Timothy D last_name: Spector - first_name: Elizabeth K full_name: Speliotes, Elizabeth K last_name: Speliotes - first_name: Michael E full_name: Goddard, Michael E last_name: Goddard - first_name: Jian full_name: Yang, Jian last_name: Yang - first_name: Peter M full_name: Visscher, Peter M last_name: Visscher citation: ama: Robinson MR, Hemani G, Medina-Gomez C, et al.

In bulk systems, without surfaces, it is well understood that such systems have a plateau in the density of vibrational modes extending down to a frequency scale ω*. This frequency is controlled by ΔZ = 〈Z〉 − 2d, the difference between the average coordination of the spheres and twice the spatial dimension, d, of the system, which vanishes at the jamming transition. In the presence of a free surface we find that there is a density of disordered vibrational modes associated with the surface that extends far below ω*. The total number of these low-frequency surface modes is controlled by ΔZ, and the profile of their decay into the bulk has two characteristic length scales, which diverge as ΔZ−1/2 and ΔZ−1 as the jamming transition is approached. article_processing_charge: No article_type: original author: - first_name: Daniel M. full_name: Sussman, Daniel M. last_name: Sussman - first_name: Carl Peter full_name: Goodrich, Carl Peter id: EB352CD2-F68A-11E9-89C5-A432E6697425 last_name: Goodrich orcid: 0000-0002-1307-5074 - first_name: Andrea J. full_name: Liu, Andrea J. last_name: Liu - first_name: Sidney R. full_name: Nagel, Sidney R. last_name: Nagel citation: ama: Sussman DM, Goodrich CP, Liu AJ, Nagel SR.

Our model uses only local interactions, such as Vicsek-type nearest-neighbor alignment, short-range repulsion, and a local boundary term. Changing the relative strength of these interactions leads to migrating swarms, rotating swarms, and jammed swarms, as well as swarms that exhibit run-and-tumble motion, alternating between migration and either rotating or jammed states. Interestingly, although a migrating swarm moves slower than an individual particle, the diffusion constant can be up to three orders of magnitude larger, suggesting that collective motion can be highly advantageous, for example, when searching for food. article_number: '032706' article_processing_charge: No article_type: original author: - first_name: Ruben full_name: van Drongelen, Ruben last_name: van Drongelen - first_name: Anshuman full_name: Pal, Anshuman last_name: Pal - first_name: Carl Peter full_name: Goodrich, Carl Peter id: EB352CD2-F68A-11E9-89C5-A432E6697425 last_name: Goodrich orcid: 0000-0002-1307-5074 - first_name: Timon full_name: Idema, Timon last_name: Idema citation: ama: van Drongelen R, Pal A, Goodrich CP, Idema T.

However, unlike their crystalline\r\ncounterparts, disordered solids are not well understood. One of the primary\r\nobstacles is the lack of a theoretical framework for thinking about disorder\r\nand its relation to mechanical properties. To this end, we study an idealized\r\nsystem of frictionless athermal soft spheres that, when compressed, undergoes a\r\njamming phase transition with diverging length scales and clean power-law\r\nsignatures. This critical point is the cornerstone of a much larger \"jamming\r\nscenario\" that has the potential to provide the essential theoretical\r\nfoundation necessary for a unified understanding of the mechanics of disordered\r\nsolids. We begin by showing that jammed sphere packings have a valid linear\r\nregime despite the presence of \"contact nonlinearities.\" We then investigate\r\nthe critical nature of the transition, focusing on diverging length scales and\r\nfinite-size effects. Next, we argue that jamming plays the same role for\r\ndisordered solids as the perfect crystal plays for crystalline solids. Not only\r\ncan it be considered an idealized starting point for understanding disordered\r\nmaterials, but it can even influence systems that have a relatively high amount\r\nof crystalline order. The behavior of solids can thus be thought of as existing\r\non a spectrum, with the perfect crystal and the jamming transition at opposing\r\nends. Finally, we introduce a new principle wherein the contribution of an\r\nindividual bond to one global property is independent of its contribution to\r\nanother. This principle allows the different global responses of a disordered\r\nsystem to be manipulated independently and provides a great deal of flexibility\r\nin designing materials with unique, textured and tunable properties." article_number: '1510.08820' article_processing_charge: No arxiv: 1 author: - first_name: Carl Peter full_name: Goodrich, Carl Peter id: EB352CD2-F68A-11E9-89C5-A432E6697425 last_name: Goodrich orcid: 0000-0002-1307-5074 citation: ama: 'Goodrich CP.

However, the costs of providing concurrency between hardware and software transactions in HyTM are still not well understood. In this paper, we propose a general model for HyTM implementations, which captures the ability of hardware transactions to buffer memory accesses. The model allows us to formally quantify and analyze the amount of overhead (instrumentation) caused by the potential presence of software transactions.We prove that (1) it is impossible to build a strictly serializable HyTM implementation that has both uninstrumented reads and writes, even for very weak progress guarantees, and (2) the instrumentation cost incurred by a hardware transaction in any progressive opaque HyTM is linear in the size of the transaction’s data set.We further describe two implementations which exhibit optimal instrumentation costs for two different progress conditions. In sum, this paper proposes the first formal HyTM model and captures for the first time the trade-off between the degree of hardware-software TM concurrency and the amount of instrumentation overhead. acknowledgement: P.
