Theory of Electromigration Failure in Polycrystalline Metal Films @ Colorado State University Electromigration failure of polycrystalline aluminum interconnects is one of the primary failure mechanisms limiting the reliability of integrated circuits. In this research, Monte Carlo simulations and analytical studies will be made of a model of electromigration failure in polycrystalline metal thin films based on percolation theory. The dependence of the average film lifetime and the distributions of lifetimes on the temperature and degree of structural disorder will be investigated. An empirical distribution for the film lifetime which is commonly employed in engineering applications will be compared to the Monte Carlo results, providing a test of this distribution for much lower failure rates than is possible experimentally. A theory of the failure kinetics will be constructed which is based on recent advances in the theory of irreversible processes in random media. As time permits, these ideas will be applied to the related problem of fatigue-induced fracture in inhomogeneous brittle materials. %%% As integrated circuits become smaller and smaller, the problem of how to connect elements within these circuits, and the circuits themselves to the outside world, becomes more critical. As these connections, or interconnects, become smaller, the probability that circuit failure may occur in the interconnect increases. Thus, an understanding of the underlying mechanisms and of the probability for interconnect failure are important for predicting lifetimes of devices. This grant is using an unconventional approach to look at this difficult problem. Percolation theory looks at conducting systems such as interconnects from a general point of view. It is not as concerned about the underlying physical details as with the more global aspects of the problem. The research proposed here will use percolation theory for the first time to try to make predictions of interconnect lifetimes and determine general parameters which affect interconnect failure. |

Evolution of Complexity in Vocal Repertoires: a Comparative Phylogenetic Study @ Ohio State University Research Foundation -Do Not Use Standard practice in animal communication studies is to define signal units subjectively. In this pilot study, the researchers will explore the feasibility of using recently developed quantitative methods to define objectively the basic signal units (notes) in the vocalizations of a monophyletic group of birds (chickadees). After assessing the performance of the computer- based SIGNAL Sound Analysis System, they will assess intra- population and inter-population variation in several common notes of representative species. They will then define the entire repertoire of a previously unstudied species in a hierarchical manner by examining clusters of similar combinations of note- types. Finally, they will assess the feasibility of using vocal data for phylogenetic reconstruction. If these preliminary studies are favorable, they will propose a follow-up project using these methods to reconstruct the evolution of vocal complexity in chickadees. This study, should it prove generally successful, will clarify hypothesized analogies between human and animal communication systems. For example, human phonemes and animal note-types function similarly as basic units of differentiable sound. Although human and animal communication systems differ quantitatively in the amount of information they can encode, they may have converged evolutionarily on a generally optimal organizational framework founded on a few dozen distinct sounds. This similarity suggests that similar constraints on perceptual processing of sound operate in both systems. |

Mathematical Sciences: Strong Mixing Conditions For Random Sequences and Random Fields @ Indiana University 9500307 Bradley Abstract This proposal concerns the study of random sequences and random fields satisfying strong mixing conditions. A random sequence is said to satisfy a "strong mixing condition" if (according to an appropriate criterion) the amount of stochastic "dependence" between the "past" and the "future" becomes uniformly arbitrarily small as the amount of "time" between past and future becomes sufficiently large. For random fields, the notions of "strong mixing" are similar, involving the uniform asymptotic independence between sets of observations as the "distance" between them becomes large. For such random sequences and random fields, both "structural properties" and limit theorems are investigated. In particular, this proposal involves a continuation of some recent work by the principal investigator in which the central limit theorem is proved for a certain class of random fields under strong mixing assumptions considerably weaker than in earlier similar theorems by other researchers. This proposal concerns the study of probabilistic models that involve "weak dependence," in which the "past" and "present" might have considerable influence on the "near future" but much less influence on the "far future." For example, the average annual national unemployment rate is one of many phenomena which appear to fit such a model; the unemployment rate for the year 1995 could presumably have considerable effect on the rate for the year 1996 or 1997 but not much effect on the rate for the year 2050. This proposal involves an investigation into various kinds of "structural properties" of probabilistic models of weak dependence, and also various long-term "laws of averages" that such models might satisfy. In particular, part of this proposal involves a continuation of some recent work by the principal investigator which considerably enlarges the class of weak dependence models that are known to satisfy a certain important law of averages. This proposal also concerns the study of similar types of probabilistic models in which observations are separated by location instead of time. |

Strong Mixing Conditions For Random Sequences @ Indiana University 9703712 Bradley Strong mixing conditions for random sequences and random fields have been useful in modeling phenomena in the real world in which observations that are ``far apart'' in time or location have only slight influence on each other. In this research, several questions are studied in connection with strongly mixing random sequences, and connections with random fields are discussed briefly. Question 1 deals with a possible ``trichotomy'' for the asymptotic behavior of the partial sums from a strictly stationary, strongly mixing sequence of random variables taking their values in a Banach space. Question 2 deals with the exact location of a part of the ``borderline'' of the central limit theorem under the (Rosenblatt) strong mixing condition. Question 3 deals with the spectral density of random sequences under a certain strong mixing condition. Question 4 deals with a possible connection (or lack of one) between two strong mixing conditions; the relevance of this question to an old conjecture of I.A. Ibragimov is discussed. In the real world, there are many phenomena which appear to be ``weakly dependent,'' in the sense that observations that are ``close'' in time or location may have considerable influence on each other, while observations that are ``far apart'' in time or location have only slight influence on each other. For example, the annual unemployment rate for the year 1998 may have considerable influence on the unemployment rates for the years 1999 and 2000, but will presumably have almost no influence on the employment rate in, say, the year 2050. Similarly, the fluctuations in the wind currents at a given location may be highly correlated with the (wind current) fluctuations ten miles away, but perhaps have no discernible correlation with the fluctuations 3000 miles away. For the modeling of such phenomena, much attention has been devoted in probability theory to a broad type of weak dependence known under the name ``stron g mixing conditions.'' An understanding of ``structural'' properties of strong mixing conditions can help in assessing their appropriateness for the modeling of a given real world phenomenon, and ``laws of averages'' connected with such conditions can provide the foundation for the statistical inference for the given phenomenon. This research deals with several questions concerning both ``structural'' properties and ``laws of averages'' in connection with various strong mixing conditions. |

Development of the Green Bank Solar Radio Burst Spectrometer: Exploring the Drivers of Space Weather @ Associated Universities Inc/National Radio Astronomy Observatory Two radio spectrometers with frequency coverage from 10 to 800 MHz will be constructed and deployed at the National Radio Quite Zone in Green Bank, WV. This effort, (i) develops a basic research tool in solar radio astrophysics for use by the wider community, (ii) remedies the lack of an important component of the United States National Space Weather Program: the need for readily available low-frequency, broadband, radio dynamic spectra in western longitudes, and (iii) provides a platform for research and development work on broadband antennas, feeds, and receivers operating from decimeter to decameter wavelengths. This program has important applications for instrument upgrades as well as future generations of instruments such as the LOw Frequency ARray (LOFAR) and the Frequency Agile Solar Radiotelescope (FASR). |

Collaborative Research: Precision Array For Probing the Epoch of Reionization (Paper) @ University of Virginia Main Campus This award is for continuation of the development of the Precision Array to Probe the Epoch of Reionization (PAPER). The focus of PAPER is the statistical detection of HI 21-cm signals from the neutral intergalactic medium (IGM) during cosmic reionization, an event corresponding to the transition from a fully neutral IGM to a highly ionized IGM caused by the UV radiation from the first stars and supermassive black holes. Probing this last unexplored phase of cosmic evolution has been called out by the Astro2010 Decade Survey as the primary area with extraordinary discovery potential in the study of cosmic structure formation, and this constitutes the main intellectual impact of this research. |

Topological Analysis of Pattern-Forming Systems @ Colorado State University Diverse phenomena in nature and the laboratory give rise to patterns such as ripples, squares, or hexagons. Examples range from laboratory models of climate in which a fluid is heated from below to hexagonal arrays of firing neurons in the region of the brain responsible for spatial memory. Two classes of pattern-forming systems motivate the work of this project. The first involves nanoscale patterns produced by bombarding a solid surface with a broad ion beam. This can produce a wide variety of self-organized nanoscale patterns. The self-assembly of nanoscale patterns that occurs when solids are irradiated is not just fascinating: in the future, ion bombardment may prove to be an important tool in the fabrication of nanostructures. It is widely believed that the burgeoning field of nanotechnology will lead to advances that will transform fields as disparate as energy, electronics, and medicine. The second class of patterns involves color changes in chemical systems in which a vapor reacts with a solid or liquid. For example, a colored pattern may appear in a solution of an important class of plant pigments called anthocyanins as it is exposed to common atmospheric pollutants. These patterns are a part of the sponsored outreach to elementary and high school students. In both of these systems, the patterns vary from highly ordered ripples or lattices with a few defects to patterns so dominated by defects that a lattice structure may not be easily recognized. These defects limit the utility of nanostructures produced by ion bombardment. They are also indicative of the underlying chemical or physical mechanism by which the patterns form, and therefore help the investigators to understand those mechanisms. In this work, the investigators develop mathematical tools to understand the formation of defects. The tools are also applied to help propose experimental methods to eliminate defects in nanopatterns produced by ion bombardment. The tools also provide insight into the mechanisms driving pattern formation. The research involves undergraduate and graduate students in integrated theoretical and experimental work. |
