title: Connectivity patterns of anchovy larvae in the Bay of Biscay from a coupled transport-bioenergetic model forced by size-structured zooplankton

description: No abstracts are to be cited without prior reference to the author.Connectivity during early life stages of pelagic fish, defined here by survival probability between spawning and early juvenile habitats, depends on a combination of sufficient food availability and low predator encounter along drift trajectories. For anchovy in the Bay of Biscay, larval transport experiments throughout the spawning season suggest accumulation of early juveniles in the offshore area of the southern Bay, as well as retention over the mid-shelf at mid-latitude. However, late summer-early autumn surveys suggest presence of juveniles only in the former region. From this observation, we set up a bioenergetic individual based model to test for the effect of food availability on survival patterns. The model couples a Lagrangian transport module to the hydrodynamic model MARS-3D, as well as a DEB (Dynamic Energy Budget) model for estimation of larval growth and mortality under starvation. Temperature is provided either from CTD casts or the hydrodynamic model, whereas food is provided by observation of size structured zooplankton biomass, from both insitu LOPC (Laser Optical Plankton Counter) and Zooscan processing of net haul samples from the Pelgas survey in May. Results suggest that for early spawning season, most of the mortality from starvation occurs at early larval stage, mostly for eggs spawned in the deepest on-shelf and off-shelf areas. The southern bay of Biscay is more suitable for growth and survival than the north at that time of the year for both temperature and food limitations reasons. The offshore occurence of late larvae in the south is consistent with observations in the area, but our model is not able to simulate a general drift of the whole distribution, that would be consistent with late larvae mostly found over the slope and off-shelf. Further simulations should investigate whether this comes from interannual and seasonal patterns explanations, or whether our model lacks an important process such as spatially explicit predation.

description: In his essay, “The Beholding Eye: Ten Versions of the Same Scene”, author D. W. Meinig offers ten different frameworks for defining landscape as: nature, habitat, artifact, system, problem, wealth, ideology, history, place, and aesthetic. Each framework focuses on different aspects of a landscape. Each of the ten frameworks, or perspectives, is assigned to a different actor: ecologist, conservationist, engineer, geomorphologist, environmental activist, developer, politician, Musqueam elder, writer, and artist. Because each actor has a different viewpoint on the landscape, the designer needs to radically shift his assumptions and approach with each new collaboration. This thesis is about ten actors with ten unique perspectives, one designer and one site, and ten unique proposals.

description: Based on the tick-by-tick stock prices from the German and American stock markets, we study the statistical properties of the distribution of the individual stocks and the index returns in highly collective and noisy intervals of trading, separately. We show that periods characterized by the strong inter-stock couplings can be associated with the distributions of index fluctuations which reveal more pronounced tails than in the case of weaker couplings in the market. During periods of strong correlations in the German market these distributions can even reveal an apparent Lévy-stable component.

description: We observe collective oscillations of a trapped, degenerate Fermi gas of $^6$Li atoms at a magnetic field just above a Feshbach resonance, where the two-body physics does not support a bound state. The gas exhibits a radial breathing mode at a frequency of 2837(05) Hz, in excellent agreement with the frequency of $ν_H\equiv\sqrt{10ν_xν_y/3}=2830(20)$ Hz predicted for a {\em hydrodynamic} Fermi gas with unitarity limited interactions. The measured damping times and frequencies are inconsistent with predictions for both the collisionless mean field regime and for collisional hydrodynamics. These observations provide the first evidence for superfluid hydrodynamics in a resonantly interacting Fermi gas.

description: Nuclear deexcitation associated with neutrino interactions and nucleon decays has a significant impact on a recent key observable for neutrino detectors: neutron multiplicity. However, most existing neutrino Monte Carlo event generators do not consider this process. For a comprehensive prediction of the neutron multiplicity, a nuclear deexcitation simulator based on TALYS named NucDeEx is developed. NucDeEx can be used for neutrino interactions and nucleon decayes for $^{12}\text{C}$ and $^{16}\text{O}$. The author provides the NucDeEx codes and sample codes for applying the NucDeex to widely-used neutrino Monte Carlo event generators, NEUT, NuWro, and GENIE.

description: Objectives: Using data from the Healthcare Cost and Utilization Project (HCUP), we estimated prevalence of individual substance use disorders (SUDs) and psychiatric comorbidities among pregnant women with opioid use disorder (OUD) in the New York State from 2009 to 2014. Methods: In this cross-sectional study, pregnancy outcome and gestational age at delivery were estimated, and OUD diagnosis during pregnancy or at delivery discharge was identified. Prevalence of SUDs and psychiatric comorbidities were then calculated. Results: Among 1,463,302 pregnant women, 8324 (0.57%) were diagnosed with OUD during pregnancy or at delivery. The most frequent SUDs or psychiatric comorbidities among pregnant women with OUD were non-opioid SUD (78.2%), followed by tobacco use disorder (74.9%), generalized anxiety disorder (38.0%), major depressive disorder (36.9%), cannabis use disorder (28.3%) and cocaine use disorder (27.4%). Conclusions: Most pregnant women with OUD were diagnosed with at least one non-opioid SUD and tobacco use disorder. Generalized anxiety disorder and major depressive disorder were also common, suggesting that mental health screenings should be prioritized for pregnant women with OUD.

description: The topological interaction arising in interlinked polymeric rings such as DNA catenanes is considered. More specifically, the free energy for a pair of linked random walk rings is derived where the distance $R$ between two segments each of which is part of a different ring is kept constant. The topology conservation is imposed by the Gauss invariant. A previous approach (M.Otto, T.A. Vilgis, Phys.Rev.Lett. {\bf 80}, 881 (1998)) to the problem is refined in several ways. It is confirmed, that asymptotically, i.e. for large $R\gg R_G$ where $R_G$ is average size of single random walk ring, the effective topological interaction (free energy) scales $\propto R^4$.

description: In the chiral unitary approach, we have studied the single Cabibbo-suppressed decays $Λ_c\to pK^+K^-$ and $Λ_c \to p π^+π^-$ by taking into account the $s$-wave meson-meson interaction as well as the contributions from the intermediate vectors $ϕ$ and $ρ^0$. Our theoretical results for the ratios of the branching fractions of $Λ_c\to p \bar{K}^{*0}$ and $Λ_c\to p ω$ with respect to the one of $Λ_c\to p ϕ$ are in agreement with the experimental data. Within the picture that the scalar resonances $f_0(500)$, $f_0(980)$, and $a_0(980)$ are dynamically generated from the pseudoscalar-pseudoscalar interactions in $s$-wave, we have calculated the $K^+K^-$ and $π^+π^-$ invariant mass distributions respectively for the decays $Λ_c\to pK^+K^-$ and $Λ_c\to pπ^+π^-$. One can find a broad bump structure for the $f_0(500)$ and a narrow peak for the $f_0(980)$ in the $π^+π^-$ invariant mass distribution of the decay $Λ_c\to pπ^+π^-$. For the $K^+K^-$ invariant mass distribution, in addition to the narrow peak for the $ϕ$ meson, there is an enhancement structure near the $K^+K^-$ threshold mainly due to the contribution from the $f_0(980)$. Both the $π^+π^-$ and $K^+K^-$ invariant mass distributions are compatible with the BESIII measurement. We encourage our experimental colleagues to measure these two decays, which would be helpful to understand the nature of the $f_0(500)$, $f_0(980)$, and $a_0(980)$.

description: The NEASQC project aims at demonstrating and advancing the capabilities of NISQ-era devices through the development of practically-relevant use-cases. Under the category of Symbolic AI and Graph Algorith-mic algorithms, one of the use-cases that is being developed is for Quantum-enabled Natural Language Processing (QNLP). The objective of the QNLP use-case in NEASQC is for the investigation, development and comparison of existing methods in classical NLP with a QNLP approach for encoding and processing sentences in a hybrid classical-quantum workflow.
 For this, deliverable D6.1 “QNLP design and specification” was presented in M6 with an overview of the background and existing approaches for classical NLP and quantum NLP along with a detailed illustration of the proposed QNLP software architecture solution and methods for testing and benchmarking the QNLP implementation.
 Deliverable D6.3 “QNLP pre-alpha prototype” is the first version of the QNLP software (pre-alpha prototype) which is primarily aimed at assessment within the NEASQC project. D6.3 implements a first version of the modules for generating training datasets (composed of sentences of specific grammatical structures), quantum circuits for training using single sentences and whole datasets, and classical NLP approaches for evaluation. This report accompanying D6.3 provides an overview of the currently implemented modules along with access and usage details of the QNLP pre-alpha prototype.

Hadronic Charmed Meson Decays Involving Tensor Mesons

Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Charmed meson decays into a pseudoscalar meson P and a tensor meson T are studied. The charm to tensor meson transition form factors are evaluated in the Isgur-Scora-Grinstein-Wise (ISGW) quark model. It is shown that the Cabibbo-allowed decay $D_s^+\to f_2(1270)π^+$ is dominated by the W-annihilation contribution and has the largest branching ratio in $D\to TP$ decays. We argue that the Cabibbo-suppressed mode $D^+\to f_2(1270)π^+$ should be suppressed by one order of magnitude relative to $D_s^+\to f_2(1270)π^+$. When the finite width effect of the tensor resonances is taken into account, the decay rate of $D\to TP$ is generally enhanced by a factor of $2\sim 3$. Except for $D_s^+\to f_2(1270)π^+$, the predicted branching ratios of $D\to TP$ decays are in general too small by one to two orders of magnitude compared to experiment. However, it is very unlikely that the $D\to T$ transition form factors can be enhanced by a factor of $3\sim 5$ within the ISGW quark model to account for the discrepancy between theory and experiment. As many of the current data are still preliminary and lack sufficient statistic significance, more accurate measurements are needed to pin down the issue.

description: A large computer program is typically divided into many hundreds or even thousands of smaller units, whose logical connections define a network in a natural way. This network reflects the internal structure of the program, and defines the ``information flow'' within the program. We show that, (1) due to its growth in time this network displays a scale-free feature in that the probability of the number of links at a node obeys a power-law distribution, and (2) as a result of performance optimization of the program the network has a small-world structure. We believe that these features are generic for large computer programs. Our work extends the previous studies on growing networks, which have mostly been for physical networks, to the domain of computer software.

Comparing extremal and thermal Explorations of Energy Landscapes

description: Using a non-thermal local search, called Extremal Optimization (EO), in conjunction with a recently developed scheme for classifying the valley structure of complex systems, we analyze a short-range spin glass. In comparison with earlier studies using a thermal algorithm with detailed balance, we determine which features of the landscape are algorithm dependent and which are inherently geometrical. Apparently a characteristic for any local search in complex energy landscapes, the time series of successive energy records found by EO also is characterized approximately by a log-Poisson statistics. Differences in the results provide additional insights into the performance of EO. In contrast with a thermal search, the extremal search visits dramatically higher energies while returning to more widely separated low-energy configurations. Two important properties of the energy landscape are independent of either algorithm: first, to find lower energy records, progressively higher energy barriers need to be overcome. Second, the Hamming distance between two consecutive low-energy records is linearly related to the height of the intervening barrier.

description: No abstracts are to be cited without prior reference to the author.First results of a coupled modelling and forecasting system for pelagic fisheries are presented. The system consists of three model subsystems: POLCOMS-ERSEM provides the physical-biogeochemical environment implemented in the domain of North-West European shelf, Sandeel Population Analysis Model describes the sandeel stocks in the North Sea and Sandeel Larval Analysis Model connects POLCOMS-ERSEM and SPAM by computing the physical-biological interaction. The model system is tested for scientific questions appearing in spatial fish stock management and marine spatial planning, including determination of local- and basin-scale Maximum Sustainable Yield, stock connectivity and source/sink structure. Our simulations indicate that sandeel stocks are currently exploited close to the MSY, but large uncertainty is associated with determining stock MSY due to stock eigen dynamics and climatic variability. Our statistical ensemble simulations indicate that the predictive horizon set by interannual climate variability is 2-6 years, after which only an asymptotic probability distribution of stock properties is predictable.

description: Nitrate (NO3-) sources and discharge were investigated using isotope and hydrochemical analyses in three river catchments draining Lake Victoria basin, Kenya. Hierarchical cluster analysis grouped Nyando, Nzoia and Sondu Miriu River stations into clusters corresponding to major land use classes of the catchments. Mixed agriculture (MA) in Nyando showed higher NO3− compared to the other land uses. Nitrate levels obtained (0.1–11.6 mg L−1) are higher than those reported in previous studies. Hydrochemistry support isotope data indicating that ammonium-based fertilizers and soil N were the major NO3- sources in tea dominated areas with average δ15N (6.5 ± 1.3 ‰), δ18O (6.7 ± 2.3 ‰) values. Manure/sewage were the main source in MA areas with average δ15N (8.4 ± 2.4 ‰), δ18O (7.8 ± 5.4 ‰) values. Sewage was the likely source in urban, residential & industrial areas recording average δ15N (10.0 ± 2.4 ‰), δ18O (6.9 ± 3.7 ‰) values. δ15N between land uses were significantly different (p 18O were similar (p = 0.4). Seasonally, inorganic/organic fertilizers influenced river NO3− mostly in the wet cropping season. Lower NO3− concentrations observed in Nyando and Sondu Miriu during dry or start-wet season could be a result of in situ denitrification.

description: Internet is the most important tool for our day-to-day life. But some rural areas are not connected by internet, so that people are not able to access the internet. Many arts and science colleges have internet facilities. This survey mainly focuses on the rural area students’ awareness and usage of internet in Libraries with special reference to St.John’s College, Palayamkottai. The results show that, 77.06 % students are accessing the internet from cyber cafe, 45.87 % of the students are accessing the internet weekly, 78.89 % of the students are sharing the information with friends, 36.69 % of the students are using the whatsapp social media, and 27.52 % of the students are using the internet for study-related work. This study concludes that government and telecommunication companies must improve the internet facility in the rural areas and colleges should install sufficient computers for accessing the internet the welfare of the students.
Curvature Effects in Gamma Ray Burst Colliding Shells

description: An elementary kinematic model for emission produced by relativistic spherical colliding shells is studied. The case of a uniform blast-wave shell with jet opening angle $θ_j \gg 1/Γ$ is considered, where $Γ$ is the Lorentz factor of the emitting shell. The shell, with comoving width $Δr^\prime$, is assumed to be illuminated for a comoving time $Δt^\prime$ and to radiate a broken power-law $νL_ν$ spectrum peaking at comoving photon energy $\e_{pk,0}^{\prime}$. Synthetic GRB pulses are calculated, and the relation between energy flux and internal comoving energy density is quantified. Curvature effects dictate that the measured $νF_ν$ flux at the measured peak photon energy $\e_{pk}$ is proportional to $\e^3_{pk}$ in the declining phase of a GRB pulse. Possible reasons for discrepancy with observations are discussed, including adiabatic and radiative cooling processes that extend the decay timescale, a nonuniform jet, or the formation of pulses by external shock processes. A prediction of a correlation between prompt emission properties and times of the optical afterglow beaming breaks is made for a cooling model, which can be tested with Swift.

description: From muon spin relaxation spectroscopy experiments, we show that the sharp peak (lambda type anomaly) detected by specific heat measurements at 54 mK for the ytterbium gallium garnet compound, Yb3Ga5O12, does not correspond to the onset of a magnetic phase transition, but to a pronounced building up of dynamical magnetic pair-correlations. Beside the lambda anomaly, a broad hump is observed at higher temperature in the specific heat of this garnet and other geometrically frustrated compounds. Comparing with other frustrated magnetic systems we infer that a ground state with long-range order is reached only when at least 1/4-1/3 of the magnetic entropy is released at the lambda transition.

description: High temperature superconductivity emerges in the vicinity of competing strongly correlated phases. In the iron-based superconductor $Ba(Fe_{1-x}Co_{x})_{2}As_{2}$, the superconducting state shares the composition-temperature phase diagram with an electronic nematic phase and an antiferromagnetic phase that break the crystalline rotational symmetry. Symmetry considerations suggest that anisotropic strain can enhance these competing phases and thus suppress the superconductivity. Here we study the effect of anisotropic strain on the superconducting transition in single crystals of $Ba(Fe_{1-x}Co_{x})_{2}As_{2}$ through electrical transport, magnetic susceptibility, and x-ray diffraction measurements. We find that in the underdoped and near-optimally doped regions of the phase diagram, the superconducting critical temperature is rapidly suppressed by both compressive and tensile stress, and in the underdoped case this suppression is enough to induce a strain-tuned superconductor to metal quantum phase transition.

(Re)Imagining Water : A Postcolonial Response to Colonial Hydrology

description: (Re)Imagining Water: A Postcolonial Response to Colonial Hydrology is a case study in reappropriating architectural representation to uncover and make visible the infrastructures of power and narrative which sustain socio-economic and political inequities. Adopting a postcolonial lens this project proceeds first with an investigation of the underlying factors which have contributed to the manifestation of the systemic and paradoxical water crisis of urban India – arguing that the current water crisis affecting millions of people in Delhi, and many millions more in other large centres in India, derives from a colonial hydrology imposed upon India by the British during their colonial rule. Influenced by the role that representation played in the colonial process the final portion of the project takes the form of a hypothetical gallery exhibit containing drawings which use architectural representation to challenge what we typically draw and in some instances the way we draw - experimenting with depictions of water not just as bounding lines but as flows that respond to the social, physical and ideological infrastructures which shape India’s urban water reality.

description: We present a novel graph embedding space (i.e., a set of measures on graphs) for performing statistical analyses of networks. Key improvements over existing approaches include discovery of "motif-hubs" (multiple overlapping significant subgraphs), computational efficiency relative to subgraph census, and flexibility (the method is easily generalizable to weighted and signed graphs). The embedding space is based on {\it scalars}, functionals of the adjacency matrix representing the network. {\it Scalars} are global, involving all nodes; although they can be related to subgraph enumeration, there is not a one-to-one mapping between scalars and subgraphs. Improvements in network randomization and significance testing--we learn the distribution rather than assuming gaussianity--are also presented. The resulting algorithm establishes a systematic approach to the identification of the most significant scalars and suggests machine-learning techniques for network classification.

description: No abstracts are to be cited without prior reference to the author.Our experience with industry-based surveys demonstrates that forming collaborative partnerships between scientists and fishermen can greatly improve the results of surveys and stock assessments. In our research, involving members of the fishing industry during each stage of the survey design and planning process was critical for improving survey results. While planning surveys, we solicited information from fishermen’s experience to define our study areas, and to choose the most appropriate times of year to sample the resource. We collaborated with fishermen to define the survey objectives, design survey trawls, develop practical protocols, and interpret results. The greatest benefits from collaborating with the fishing industry have been realized during field work. Fishing vessels provide a cost-effective platform for fisheries-independent surveys. The local ecological knowledge of our industry partners allowed us to extend the sampling area to habitats that are difficult to trawl and are typically undersampled by research vessels. Fishermen’s practical experience was also valuable for minimizing lost sampling time when problems arose, such as trawl damage. After field work and data analysis were completed, we found that it is important to share the results of the surveys with our industry collaborators, because their unique perspectives offered important insights into the results.

description: Spin-waves have been studied for data storage, communication and logic circuits in the field of spintronics based on their potential to substitute electrons. Recent discovery of magnetism in two-dimensional (2D) systems such as monolayer CrI$_3$ and Cr$_2$Ge$_2$Te$_6$ has led to a renewed interest in such applications of magnetism in the 2D limit. Here we present direct evidence of standing spin-waves along with the uniform precessional resonance modes in van der Waals magnetic material, CrCl$_3$. Our experiment is the first direct observation of standing spin-wave modes, set up across a thickness of 20 $μ$m, in a van der Waals material. We detect standing spin-waves in the vicinity of both, optical and acoustic, branches of the antiferromagnetic resonance. We also observe magnon-magnon coupling, softening of resonance modes with temperature and extract the evolution of interlayer exchange field as a function of temperature.

description: Metal halide perovskite nanowires (PrvNWs) have recently emerged as an interesting path for nanostructured solar cells. Here, we model the absorption of light in PrvNW arrays for varying diameter and length of the PrvNWs and period for the array by solving the Maxwell equations. For long enough bare PrvNW arrays, we find that the optimum diameter is fixed to that which places the absorption peak from the HE$_{11}$ waveguide mode in the PrvNWs to the vicinity of the bandgap wavelength. In contrast, when we include a transparent conductive oxide (TCO) top contact layer, the optimum diameter shifts to a larger value by 100 nm. The origin of this shift is traced to a reduced reflection at the interface between the TCO layer and the PrvNW array when the PrvNW's diameter is larger. Overall, we find that 1500 nm long PrvNWs can reach 90% of the broadband absorption potential, making this system of high interest for photovoltaics.

description: Twenty years of gravity observations from various satellite missions have provided unique data about mass redistribution processes in the Earth system. This paper studies the benefit of enhanced electrostatic and novel optical accelerometers and gradiometers for the future gravimetry missions. One of the limiting factors in the current space gravimetry missions is the drift of the Electrostatic Accelerometers (EA). This study focuses on the modeling of enhanced EAs with laser-interferometric readout, so called 'optical accelerometers', and on evaluating their performance for gravity field recovery in future satellite missions. In this paper, we simulate gravimetry missions in multiple scopes, applying the various software modules for satellite dynamics integration, accelerometer (ACC) and gradiometer simulation and gravity field recovery. The total noise budget of the modeled enhanced Electrostatic and optical ACCs show a similar sensitivity as the ACC concepts from other research groups. Parametrization w.r.t. ACCs test mass (TM) weight and the gap between the test mass and surrounding electrode housing confirmed previously known results that an ACC with a heavier TM and larger gap will have better performance. Our results suggest that the anticipated gain of novel ACCs might at some point be potentially limited by noise from the inter-satellite laser ranging interferometry. In order to present the advantage of the novel sensors, time-variable background models and associated aliasing errors were not considered in our simulations. Utilization of enhanced EA and optical ACC show a significant improvement of accuracy w.r.t. current GRACE-like EA. Also, their benefit in double satellite pairs in a so called 'Bender' constellations as well as in the combination of low-low satellite-to-satellite tracking with cross-track gradiometry has been investigated.

description: The determination of protein functions is one of the most challenging problems of the post-genomic era. The sequencing of entire genomes and the possibility to access gene's co-expression patterns has moved the attention from the study of single proteins or small complexes to that of the entire proteome. In this context, the search for reliable methods for proteins' function assignment is of uttermost importance. Previous approaches to deduce the unknown function of a class of proteins have exploited sequence similarities or clustering of co-regulated genes, phylogenetic profiles, protein-protein interactions, and protein complexes. We propose to assign functional classes to proteins from their network of physical interactions, by minimizing the number of interacting proteins with different categories. The function assignment is made on a global scale and depends on the entire connectivity pattern of the protein network. Multiple functional assignments are made possible as a consequence of the existence of multiple equivalent solutions. The method is applied to the yeast Saccharomices Cerevisiae protein-protein interaction network. Robustness is tested in presence of a high percentage of unclassified proteins and under deletion/insertion of interactions.

description: The Jagiellonian positron emission tomograph (J-PET) is a multi-purpose device built out of plastic scintillators. With large acceptance and high angular resolution, it is suitable for the studies of various phenomena such as discrete symmetries in decay of positronium atom or entangled states of photons as well as medical imaging. J-PET enables the measurement of momenta together with photon polarization related observables. Large acceptance and high granularity of the J-PET detector enables measurement of ortho-positronium decays into three photons in the whole phase-space. In this paper we present the search of the C-forbidden decays of positronium with the J-PET detector.

description: No abstracts are to be cited without prior reference to the author.Annual surveys of marine resources are often used to monitor changes in population composition and abundance. For those surveys based on a probability design, improvements to the probability design are evaluated with respect to the resultant increase in precision of the survey estimates. While these precision estimates will reflect the current efficiency of the survey design, improvements to the survey design will only carry over to stock assessment advice if the survey precision estimates are included in the process to generate this advice. Advice on catch levels for sea scallop populations (Placopecten magellanicus) around Nova Scotia is developed using a delay-difference state space population model and data collected annually using probability survey designs. Survey estimates of precision can be directly included in to the observation model component of the population model and will affect the provision of advice in terms of probabilities of exceeding reference points and predictions of future biomass. In this paper we present results on the sensitivity of stock assessment advice to changes in the level of precision of survey estimates

description: Consider a Markov chain on an infinite tree T=(V,E) rooted at ρ. In such a chain, once the initial root state σ(ρ) is chosen, each vertex iteratively chooses its state from the one of its parent by an application of a Markov transition rule (and all such applications are independent). Let μ_j denote the resulting measure for σ(ρ)=j. The resulting measure μ_j is defined on configurations σ=(σ(x))_{x\in V}\in A^V, where A is some finite set. Let μ_j^n denote the restriction of μto the sigma-algebra generated by the variables σ(x), where x is at distance exactly n from ρ. Letting α_n=max_{i,j\in A}d_{TV}(μ_i^n,μ_j^n), where d_{TV} denotes total variation distance, we say that the reconstruction problem is solvable if lim inf_{n\to\infty}α_n>0. Reconstruction solvability roughly means that the nth level of the tree contains a nonvanishing amount of information on the root of the tree as n\to\infty. In this paper we study the problem of robust reconstruction. Let νbe a nondegenerate distribution on A and ε>0. Let σbe chosen according to μ_j^n and σ' be obtained from σby letting for each node independently, σ(v)=σ'(v) with probability 1-εand σ'(v) be an independent sample from νotherwise. We denote by μ_j^n[ν,ε] the resulting measure on σ'. The measure μ_j^n[ν,ε] is a perturbation of the measure μ_j^n.
