description: Heavy-flavor jets are powerful tools to gain insight into the in-medium partonic energy-loss mechanisms and the quark-gluon plasma's (QGP) transport properties in high-energy nuclear collisions. In this work we present the first theoretical study of the longitudinal momentum fraction $z_{||}$ carried by heavy-flavor mesons in jets in Pb+Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. The p+p baseline is provided by POWHEG+PYTHIA8, which matches the next-to-leading-order hard processes with the parton shower. We employ a Monte Carlo transport model, which considers the collisional and radiative partonic energy loss, to simulate the evolution of heavy-flavor jets in the expanding QGP medium. We observe steeper $z_{||}$ distributions of $\rm{B^0}$ jets compared to those of $\rm{D^0}$ jets at the same kinematics region in p+p collisions, which may be a hint of the harder jet fragmentation function of b jets compared to c jets in vacuum. In A+A collisions, it is shown that the jet quenching effect would generally decrease the values of $z_{||}$. We have made a systematical study on how several factors, including jet $p_{\rm{T}}$, jet radius $R$, and collision centrality, would influence the medium modification of $z_{||}$ distributions of a $\rm{D^0}$ jet. In addition, we predict visibly stronger nuclear modifications of $\rm{B^0}$-jet $z_{||}$ distributions compared to a $\rm{D^0}$ jet within the same $p_{\rm T}$ windows as a result of the much steeper initial $z_{||}$ distribution of the $\rm{B^0}$ jet in vacuum.

The Burden of Risk Aversion in Mean-Risk Selfish Routing

description: Considering congestion games with uncertain delays, we compute the inefficiency introduced in network routing by risk-averse agents. At equilibrium, agents may select paths that do not minimize the expected latency so as to obtain lower variability. A social planner, who is likely to be more risk neutral than agents because it operates at a longer time-scale, quantifies social cost with the total expected delay along routes. From that perspective, agents may make suboptimal decisions that degrade long-term quality. We define the {\em price of risk aversion} (PRA) as the worst-case ratio of the social cost at a risk-averse Wardrop equilibrium to that where agents are risk-neutral. For networks with general delay functions and a single source-sink pair, we show that the PRA depends linearly on the agents' risk tolerance and on the degree of variability present in the network. In contrast to the {\em price of anarchy}, in general the PRA increases when the network gets larger but it does not depend on the shape of the delay functions. To get this result we rely on a combinatorial proof that employs alternating paths that are reminiscent of those used in max-flow algorithms. For {\em series-parallel} (SP) graphs, the PRA becomes independent of the network topology and its size. As a result of independent interest, we prove that for SP networks with deterministic delays, Wardrop equilibria {\em maximize} the shortest-path objective among all feasible flows.

description: We have performed systematic resistivity and inelastic neutron scattering measurements on Fe$_{0.98-z}$Ni$_z$Te$_{0.5}$Se$_{0.5}$ samples to study the impact of Ni substitution on the transport properties and the low-energy ($\le$ 12 meV) magnetic excitations. It is found that, with increasing Ni doping, both the conductivity and superconductivity are gradually suppressed; in contrast, the low-energy magnetic spectral weight changes little. Comparing with the impact of Co and Cu substitution, we find that the effects on conductivity and superconductivity for the same degree of substitution grow systematically as the atomic number of the substituent deviates from that of Fe. The impact of the substituents as scattering centers appears to be greater than any contribution to carrier concentration. The fact that low-energy magnetic spectral weight is not reduced by increased electron scattering indicates that the existence of antiferromagnetic correlations does not depend on electronic states close to the Fermi energy.

description: The purpose of this article is to study the algorithmic complexity of the Besicovitch stability of noisy subshifts of finite type, a notion studied in a previous article. First, we exhibit an unstable aperiodic tiling, and then see how it can serve as a building block to implement several reductions from classical undecidable problems on Turing machines. It will follow that the question of stability of subshifts of finite type is undecidable, and the strongest lower bound we obtain in the arithmetical hierarchy is $Π_2$-hardness. Lastly, we prove that this decision problem, which requires to quantify over an uncountable set of probability measures, has a $Π_4$ upper bound.

Lead Isotopes as a New Tracer for Detecting Coal Fly Ash in the Environment

description: Lead (Pb) isotopes have been widely used to delineate Pb pollutants in the environment. Here, we present, for the first time, a systematic analysis of Pb isotopes in coal fly ash derived from coals from the three major coal-producing basins in the United States. Fly ash samples from Powder River Basin coals have higher 206Pb/207Pb ratios (1.2271 ± 0.0086, n = 7) than Appalachian Basin fly ash (1.2173 ± 0.0060, n = 16), while Illinois Basin fly ash samples are much more variable (1.2270 ± 0.0140, n = 22). The Pb isotopic signature of fly ash is distinguishable from that of major anthropogenic Pb sources in the United States, including leaded gasoline and paint, as well as the Pb isotope ratios of naturally occurring sediments and soils. Lead isotopic analysis of sediments from Sutton Lake in North Carolina, where other indicators have identified the occurrence of fly ash solids from unmonitored coal ash spills, shows a well-defined mixing between the Pb of unimpacted sediments and that of Appalachian Basin fly ash. This result further validates the applicability of Pb isotopes as a new tracer for detecting the occurrence of coal fly ash in the environment.

description: I gave this presentation as part of the Observations Working Group session at the SATCON1 workshop. I presented results from Section 6 of Tyson et al. 2020. Five SpaceX Starlink satellites launched in January 2020 were observed by the Blanco 4-m telescope's Dark Energy Camera (DECam) in March 2020. One of these is DarkSat, which has an experimental darkening mitigation. The main result is that DarkSat is about 6th magnitude in g-band while its brighter siblings are about 5th magnitude. Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will require low-earth-orbit satellites such as Starlink to be closer to 7th magnitude or fainter to mitigate the worst systematic errors likely to result from image artifact correction. For a detailed discussion, please see Tyson et al. 2020.

Publisher: name: Blackwell Publishing Ltd

description: Dense drill core and subsurface mapping at the Questa molybdenum mine, combined with regional structural tilt, permit detailed 3-D documentation of plutonic rocks in the Latir magmatic center, New Mexico. Integration of mapping with new and existing U-Pb zircon geochronology (a total of 136 analyses from 15 intrusions) allows for examination of the space-time evolution of the Bouguer gravity low associated with the magmatic center. The Questa batholith at Latir was assembled by discrete pulses of magma over a 5.5-Ma interval (approximately 25.3–19.8 Ma) of generally downward stacking intrusions following the volcanic peak at 25.52 Ma. This contradicts interpretations that the Bouguer gravity lows here and elsewhere are the plutonic crystal cumulate residues left after extraction of large-volume silicic magmas. Estimates of magma flux based on the volume of plutonic rocks inferred from gravity data combined with the extrapolation of geochronology of exposed surface rocks are questionable because the assumption that unexposed plutonic rocks are the same age as dated surface rocks directly above them likely underestimates the true range of ages.

description: As part of its HL-LHC upgrade program, the CMS collaboration is replacing its existing endcap calorimeters with a high-granularity calorimeter (CE). The new calorimeter is a sampling calorimeter with unprecedented transverse and longitudinal readout for both electromagnetic and hadronic compartments. Due to its compactness, intrinsic time resolution, and radiation hardness, silicon has been chosen as active material for the regions exposed to higher radiation levels. The silicon sensors are fabricated as 20 cm (8") wide hexagonal wafers and are segmented into several hundred pads which are read out individually. As part of the sensor qualification strategy, 8" sensor irradiation with neutrons has been conducted at the Rhode Island Nuclear Science Center (RINSC) and followed by their electrical characterisation in 2020-21. The completion of this important milestone in the CE's R&D program is documented in this paper and it provides detailed account of the associated infrastructure and procedures. The results on the electrical properties of the irradiated CE silicon sensors are presented.

description: This paper presents a rotation-search-based approach for addressing the star identification (Star-ID) problem. The proposed algorithm, ROSIA, is a heuristics-free algorithm that seeks the optimal rotation that maximally aligns the input and catalog stars in their respective coordinates. ROSIA searches the rotation space systematically with the Branch-and-Bound (BnB) method. Crucially affecting the runtime feasibility of ROSIA is the upper bound function that prioritizes the search space. In this paper, we make a theoretical contribution by proposing a tight (provable) upper bound function that enables a 400x speed-up compared to an existing formulation. Coupling the bounding function with an efficient evaluation scheme that leverages stereographic projection and the R-tree data structure, ROSIA achieves feasible operational speed on embedded processors with state-of-the-art performances under different sources of noise. The source code of ROSIA is available at https://github.com/ckchng/ROSIA.

description: Recentemente testemunhamos, no Brasil, uma amostra dos efeitos catastróficos que as alterações climáticas podem produzir. É imperioso que a classe de conservadores-restauradores brasileiros implemente uma urgente reforma no modo de atuação, atentando-se para as prioritárias  medidas de conservação-restauração sustentável. A conservação-restauração desenvolve-se a passos lentos, dado que nós brasileiros, historicamente enfrentamos a escassez de recursos, as diferenças metodológicas, processuais e deontológicas, todas essas acentuadas pela falta do reconhecimento profissional do conservador-restaurador. Essas problemáticas somadas à preocupação do papel desse profissional frente à sustentabilidade foram questões norteadoras que conduziram um profundo estudo de caso através da obra impressa por Guy Spitzer.O objeto de estudo  de caso, a obra “Nature Morte à la Charlotte”, de Pablo Picasso (fração 159/350), incitou uma estratégia metodológica na qual se espera poder servir de alicerce para a prática profissional em casos análogos. A obra apresenta graves acidificação e contaminação fúngica com comprometimento da leitura da peça. Em adição, possui inscrições a caneta esferográfica e carimbo de autenticidade, que representam um nível de dificuldade mais elevado quanto aos tratamentos necessários do suporte (papel). Os processos interventivos foram planejados de forma que fosse minimizada utilização de água, bem como feita a substituição dos produtos químicos não biodegradáveis por alternativas não contaminantes para o meio ambiente e contou com a criação de um sistema de reaproveitamento de materiais utilizados nos processos de preservação. Os resultados desse processo, estabeleceram diretrizes que podem vir a contribuir como modelo para a implementação prática de conservação verde, contemplando desde o profissional de iniciativa privada até instituições culturais.

description: Water, bedrock, and saprolite samples from the Neuse and Cape Fear River basins, North Carolina, were analyzed for 87Sr/86Sr and [Sr] to evaluate the control of exposed bedrock on fluvial Sr isotopic compositions and the influence of geology on Sr delivered to the ocean. The 87Sr/86Sr and [Sr] of the two rivers start low and rise downstream, eventually approximating recent ocean isotopic compositions before entering their estuaries. Groundwater samples from the headwaters have 87Sr/86Sr ratios that are lower than expected from the dominant exposed bedrock. The isotopic compositions of bedrock and saprolite samples vary predictably with rock type and age and show no correlation with degree of weathering. The data indicate that dominant surficial bedrock is not the primary source of Sr to the headwaters of the rivers. Rather, mafic dikes that focus groundwater flow and are more easily weathered than their silicic hosts impact the 87Sr/86Sr of the waters more than their limited exposure might suggest. Furthermore, the Sr isotopic composition of the water delivered to the marine environment is buffered by groundwater from coastal plain sedimentary rocks, leaving no evidence of upstream geology. The data suggest that rock type and structure exert significant control on the Sr isotope geochemistry of groundwater that enters into streams. Considering the global fluvial Sr budget, these results emphasize that, in some settings, (1) rock exposure area can be a poor indication of the geologic influence on Sr isotopic compositions of surface waters, and (2) downstream Sr isotopic compositions may not reflect upstream geology.

description: The In-Vessel Viewing System (IVVS) units proposed for ITER are deployed to perform in-vessel examination. During plasma operations, the IVVS is located beyond the vacuum vessel, with shielding blocks envisaged to protect components from neutron damage and reduce shutdown dose rate (SDR) levels. Analyses were conducted to determine the effectiveness of several shielding configurations. The neutron response of the system was assessed using global variance reduction techniques and a surface source, and shutdown dose rate calculations were undertaken using MCR2S. Unshielded, the absorbed dose to piezoelectric motors (PZT) was found to be below stable limits, however activation of the primary closure plate (PCP) was prohibitively high. A scenario with shielding blocks at probe level showed significantly reduced PCP contact dose rate, however still marginally exceeded port cell requirements. The addition of shielding blocks at the bioshield plug demonstrated PCP contact dose rates below project requirements. SDR levels in contact with the isolated IVVS cartridge were found to marginally exceed the hands-on maintenance limit. For engineering feasibility, shielding blocks at bioshield level are to be avoided, however the port cell SDR field requires further consideration. In addition, alternative low-activation steels are being considered for the IVVS cartridge.

description: The Talamanca Cordillera in the Central America Arc (Costa Rica-Panama) preserves the record of the geochemical evolution from an intraoceanic arc to a juvenile continental arc in an active subduction zone, making it a testbed to explore processes that resulted in juvenile continental crust formation and explore potential mechanisms of early continental crust generation. Here we present a comprehensive set of geochronological, geochemical, and petrological data from the Talamanca Cordillera that tracks the key turning point (12–8 Ma) from the evolution of an oceanic arc depleted in incompatible elements to a juvenile continent. Most plutonic rocks from this transition and postintrusive rocks share striking similarities with average upper continental crust and Archean tonalite, trondhjemite, and granodiorite. We complement these data with seismic studies across the arc. Seismic velocities within the Caribbean Plate (basement of the arc) show a relatively uniform lateral structure consistent with a thick mafic large igneous province. Comparisons of seismic velocity profiles in the middle and lower crust beneath the active arc and remnant Miocene arc suggest a transition toward more felsic compositions as the volcanic center migrated toward the location of the modern arc. Seismic velocities along the modern arc in Costa Rica compared with other active arcs and average continental crust suggest an intermediate composition beneath the active arc in Costa Rica closer to average crust. Our geochemical modeling and radiogenic isotopes systematics suggest that input components from melting of the subducting Galapagos hotspot tracks are required for this compositional change.

These observations are mainly based on results on azimuthal anisotropies, but also on particle spectra of identified particles, perfectly compatible with a hydrodynamic evolution. Surprisingly, in p-Pb collisions one observes a very similar behavior, and to some extent even in p-p. We take these experimental observations as a strong support for a unified approach to describe proton-proton (p-p), proton-nucleus (p-A), and nucleus-nucleus (A-A) collisions, with a plasma formation even in tiny systems as in p-p scatterings.

description: A search for pair-produced scalar and vector leptoquarks decaying into quarks and leptons of different generations is presented. It uses the full LHC Run 2 (2015-2018) data set of 139 fb$^{-1}$ collected with the ATLAS detector in proton-proton collisions at a centre-of-mass energy of $\sqrt{s} = 13$ TeV. Scalar leptoquarks with charge -(1/3)e as well as scalar and vector leptoquarks with charge +(2/3)e are considered. All possible decays of the pair-produced leptoquarks into quarks of the third generation (t, b) and charged or neutral leptons of the first or second generation ($e, μ, ν$) with exactly one electron or muon in the final state are investigated. No significant deviations from the Standard Model expectation are observed. Upper limits on the production cross-section are provided for eight models as a function of the leptoquark mass and the branching ratio of the leptoquark into the charged or neutral lepton. In addition, lower limits on the leptoquark masses are derived for all models across a range of branching ratios. Two of these models have the goal of providing an explanation for the recent B-anomalies. In both models, a vector leptoquark decays into charged and neutral leptons of the second generation with a similar branching fraction. Lower limits of 1980 GeV and 1710 GeV are set on the leptoquark mass for these two models.

description: We introduce with geometric means a density matrix decomposition of a multipartite quantum system of a finite dimension into two density matrices: a separable one, also known as the best separable approximation, and an essentially entangled one, which contains no product states components. We show that this convex decomposition can be achieved in practice with the help of an algorithm based on linear programming, which in the general case scales polynomially with the dimension of the multipartite system. Furthermore, we suggest methods for analyzing the multipartite entanglement content of the essentially entangled component and derive analytically an upper bound for its rank. We illustrate the algorithm at an example of a composed system of total dimension 12 undergoing loss of coherence due to classical noise and we trace the time evolution of its essentially entangled component. We suggest a "geometric" description of entanglement dynamics and show how it explains the well-known phenomena of sudden death and revival of multipartite entanglement.

A more informative way to name plutonic rocks

description: The International Union of Geological Sciences (IUGS) system for rock classification, introduced more than 40 years ago, has served geologists well but suffers from the problem of dividing a continuum of rock compositions into arbitrary bins. As a result, closely related rocks can be given unrelated names (e.g., granodiorite and tonalite), and the names themselves, which were generally derived from the names of places or people, rarely contribute to understanding the processes that generate the diversity of igneous rocks. Here we propose a quantitative modification to the IUGS system that reduces the number of distinct names but more effectively communicates the inherent variability of plutonic rocks. The system recognizes that mapped plutonic rock units are characterized by recognizable textures and mineral assemblages, but that mineral proportions within those units can be highly variable. Adding quantitative data to rock names is an important step toward moving geologic field observations into quantitative digital form and preparing them for advanced data mining and analysis.

description: Starobinsky inflation is an attractive, fundamental model to explain the Planck measurements, and its higher-order extension may allow us to probe quantum gravity effects. We show that future CMB data combined with the 21cm intensity map from SKA will meaningfully probe such an extended Starobinsky model. A combined analysis will provide a precise measurement and intriguing insight into inflationary dynamics, even accounting for correlations with astrophysical parameters.

description: We continue our study of rigorous renormalization group (RG) maps for tensor networks that was begun in arXiv:2107.11464. In this paper we construct a rigorous RG map for 2D tensor networks whose domain includes tensors that represent the 2D Ising model at low temperatures with a magnetic field $h$. We prove that the RG map has two stable fixed points, corresponding to the two ground states, and one unstable fixed point which is an example of a discontinuity fixed point. For the Ising model at low temperatures the RG map flows to one of the stable fixed points if $h \neq 0$, and to the discontinuity fixed point if $h=0$. In addition to the nearest neighbor and magnetic field terms in the Hamiltonian, we can include small terms that need not be spin-flip invariant. In this case we prove there is a critical value $h_c$ of the field (which depends on these additional small interactions and the temperature) such that the RG map flows to the discontinuity fixed point if $h=h_c$ and to one of the stable fixed points otherwise. We use our RG map to give a new proof of previous results on the first-order transition, namely, that the free energy is analytic for $h \neq h_c$, and the magnetization is discontinuous at $h = h_c$. The construction of our low temperature RG map, in particular the disentangler, is surprisingly very similar to the construction of the map in arXiv:2107.11464 for the high temperature phase. We also give a pedagogical discussion of some general rigorous transformations for infinite dimensional tensor networks and an overview of the proof of stability of the high temperature fixed point for the RG map in arXiv:2107.11464.

description: This thesis focuses on the field of 5G network security, specifically in the area of programmable networks that use Kubernetes as a VNF controller. For these operating environments, there are currently no available solutions for efficient real-time monitoring and log aggregation that will enable network administrators to evaluate performace and security threats. While some general-purpose industry-standard solutions offer a number of features, such as leveled logs, advanced text formatting, built-in visualizations and frontends, their use introduces significant performance overheads and requires a lot of customization effort in order to be deployed in live networks.
In this thesis, a new metrics system, developed in Golang, is introduced to alleviate the shortcomings of the aforementioned solutions. It enables efficient real-time monitoring and evaluation of network services and its parser-analyzer captures information related to network service performance and security and analyzes it in order to provide valuable insights. Automation scripts and Ansible configurations were also developed to facilitate and automate the monitoring and evaluation process, offering a more efficient and effective means of measuring the performance of network services as well as the effectiveness of the security countermeasures deployed in them.
The developed metrics system has been deployed, tested and validated in the PRINCIPALS research project. PRINCIPALS strives to enhance active network service management and security through the provision of security primitives to counter diverse types of attacks. The metrics system  is an integral  component of the PRINCIPALS framework, providing real-time benchmarking capabilities, as well as serving as the main logging mechanism.

description: We analyze nonequilibrium lattice models with up-down symmetry and two absorbing states by mean-field approximations and numerical simulations in two and three dimensions. The phase diagram displays three phases: paramagnetic, ferromagnetic and absorbing. The transition line between the first two phases belongs to the Ising universality class and between the last two, to the direct percolation universality class. The two lines meet at the point describing the voter model and the size $\ell$ of the ferromagnetic phase vanishes with the distance $\varepsilon$ to the voter point as $\ell\sim\varepsilon$, with possible logarithm corrections in two dimensions.
Dike intrusion and deformation during growth of the Half Dome pluton, Yosemite National Park, California

description: Meter-scale mapping of the Late Cretaceous Half Dome Granodiorite of the Tuolumne Intrusive Suite (TIS) near Tenaya Lake, Yosemite National Park, defines an intricate internal structure that reflects a combination of incremental pluton growth by diking and internal deformation as the pluton grew. At least four ages of dikes of layered granodiorite are defined by crosscutting relations. Because dikes thicker than 1 m invariably contain multiple cycles of layering that field relations indicate record multiple intrusive increments, dozens of discrete intrusive events are likely. The kinematic pattern of dilation across dikes, offset lithologic markers across dikes, shearing of mafic enclaves and magmatic layering, and folding of dikes defines a synintrusive bulk strain field characterized by E-W extension and N-S contraction, with net volume increase in the extension direction. The geometric and kinematic pattern of the deformation are consistent with current understanding of Late Cretaceous Cordilleran tectonics and suggest that regional tectonic dilation played a significant role in making upper-crustal space for the growing pluton. Narrow shear zones offset lithologic markers and produced extreme strains, yet no rock fabric is preserved in the zones. This indicates that late-magmatic to subsolidus recrystallization, previously inferred in the TIS based on textural and mineralogical observations, greatly modified rock textures and obscured both the intricate internal structure of the pluton and the importance of synemplacement deformation.
