Revisiting Galvanomagnetic Effects In Conducting Ferromagnets, Raymond Walter, Michel Viret, Surendra Singh, Laurent Bellaiche Dec 2015

Revisiting Galvanomagnetic Effects In Conducting Ferromagnets, Raymond Walter, Michel Viret, Surendra Singh, Laurent Bellaiche

Raymond Walter

The recently proposed coupling between the angular momentum density and magnetic moments is shown
to provide a straightforward alternative explanation for galvanomagnetic eects, i.e., for both anisotropic
magnetoresistance (AMR) and planar Hall eect (PHE). Such coupling naturally reproduces the general
formula associated with AMR and PHE and allows for the occurrence of so-called `negative AMR'. This
coupling also provides a unifying link between AMR, PHE and the anomalous Hall eect (AHE) since this
same coupling was previously found to give rise to AHE (Bellaiche et al 2013 Phys. Rev. B 88 161102).

Universal Memory Architectures For Autonomous Machines, Dan Guralnik, Daniel E. Koditschek Dec 2015

Universal Memory Architectures For Autonomous Machines, Dan Guralnik, Daniel E. Koditschek

Dan Guralnik

We propose a self-organizing memory architecture (UMA) for perceptual experience provably capable of supporting autonomous learning and goal-directed problem solving in the absence of any prior information about the agent’s environment. The architecture is simple enough to ensure (1) a quadratic bound (in the number of available sensors) on space requirements, and (2) a quadratic bound on the time-complexity of the update-execute cycle. At the same time, it is sufficiently complex to provide the agent with an internal representation which is (3) minimal among all representations which account for every sensory equivalence class consistent with the agent’s belief state; (4) …

Asymmetric Forecast Densities For U.S. Macroeconomic Variables From A Gaussian Copula Model Of Cross-Sectional And Serial Dependence, Michael S. Smith, Shaun Vahey Dec 2015

Asymmetric Forecast Densities For U.S. Macroeconomic Variables From A Gaussian Copula Model Of Cross-Sectional And Serial Dependence, Michael S. Smith, Shaun Vahey

Michael Stanley Smith

Most existing reduced-form macroeconomic multivariate time series models employ elliptical disturbances, so that the forecast densities produced are symmetric. In this paper, we use a copula model with asymmetric margins to produce forecast densities with the scope for severe departures from symmetry. Empirical and skew t distributions are employed for the margins, and a high-dimensional Gaussian copula is used to jointly capture cross-sectional and (multivariate) serial dependence. The copula parameter matrix is given by the correlation matrix of a latent stationary and Markov vector autoregression (VAR). We show that the likelihood can be evaluated efficiently using the unique partial correlations, …

Role Of Multiple High-Capacity Irrigation Wells On A Surficial Sand And Gravel Aquifer, Logan Seipel, Eric Wade Peterson, David H. Malone, Jason F. Thomason Dec 2015

Role Of Multiple High-Capacity Irrigation Wells On A Surficial Sand And Gravel Aquifer, Logan Seipel, Eric Wade Peterson, David H. Malone, Jason F. Thomason

Eric Wade Peterson

Within McHenry County, IL, the fastest growing county in Illinois, groundwater is used for 100% of
the water needs. Concerns over water resources have prompted the investigation of the surficial
sand and gravel aquifers of the county. While the eastern portion of the county is urbanizing, the
western portion remains devoted to agriculture. High-capacity irrigation wells screened within
the surficial sand and gravel aquifer are used for crop production. To assess the impacts of the ir-
rigation wells on the aquifer, a groundwater flow model was developed to examine five different
scenarios reflecting drought conditions and increased pumping. Results show …

Mapping The Patent Landscape Of Synthetic Biology For Fine Chemical Production Pathways, Pablo Carbonell, Abdullah Gok, Philip Shapira, Jean-Loup Faulon Dec 2015

Mapping The Patent Landscape Of Synthetic Biology For Fine Chemical Production Pathways, Pablo Carbonell, Abdullah Gok, Philip Shapira, Jean-Loup Faulon

Philip Shapira

A goal of synthetic biology bio-foundries is to innovate through an iterative design/build/test/learn pipeline. In assessing the value of new chemical production routes, the intellectual property (IP) novelty of the pathway is important. Exploratory studies can be carried using knowledge of the patent/IP landscape for synthetic biology and metabolic engineering. In this paper, we perform an assessment of pathways as potential targets for chemical production across the full catalogue of reachable chemicals in the extended metabolic space of chassis organisms, as computed by the retrosynthesis-based algorithm RetroPath. Our database for reactions processed by sequences in heterologous pathways was screened against …

An Agent-Based Modeling Approach To Determine Winter Survival Rates Of American Robins And Eastern Bluebirds, Samuel Iselin, Shannon Segin, Alex Capaldi Dec 2015

An Agent-Based Modeling Approach To Determine Winter Survival Rates Of American Robins And Eastern Bluebirds, Samuel Iselin, Shannon Segin, Alex Capaldi

Alex Capaldi

American Robins (Turdus migratorius) and Eastern Bluebirds (Sialia sialis) are two species of migratory thrushes that breed in Northwest Indiana but historically are uncommon during the winter season. These trends have changed recently, and both species are seen more abundantly during the winter. Recently invaded non-native fruiting plants continue to provide nutrients for the birds throughout the winter and may contribute to the increased avian populations during that time. To measure the effect these food sources contribute to thrush wintering habits, we created an agent-based computer model to simulate the birds' movement in Northwest Indiana along …

Shift Operators Defined In The Riordan Group And Their Applications, Tian-Xiao He Dec 2015

Shift Operators Defined In The Riordan Group And Their Applications, Tian-Xiao He

Tian-Xiao He

In this paper, we discuss a linear operator T dened in Riordan group R by using the upper shift matrix U and lower shift matrix UT ; namely for each R 2 R, T : R 7! URUT . Some isomorphic properties of the operator T and the structures of its range sets for dierent domains are studied. By using the operator T and the properties of Bell subgroup of R, the Riordan type Chu-Vandermonde identities and the Riordan equivalent identities of Format Last Theorem and Beal Conjecture are shown. The applications of the shift operators to the complementary Riordan …

Row Sums And Alternating Sums Of Riordan Arrays, Tian-Xiao He, Louis W. Shapiro Dec 2015

Row Sums And Alternating Sums Of Riordan Arrays, Tian-Xiao He, Louis W. Shapiro

Tian-Xiao He

Here we use row sum generating functions and alternating sum generating functions to characterize Riordan arrays and subgroups of the Riordan group. Numerous applications and examples are presented which include the construction of Girard-Waring type identities. We also show the extensions to weighted sum (generating) functions,
called the expected value (generating) functions of Riordan arrays.

Stratigraphy And Extent Of The Pearl-Ashmore Aquifer, Mchenry County, Il, Usa, Drew C. Carlock, David H. Malone, Jason F. Thomason, Eric Wade Peterson Dec 2015

Stratigraphy And Extent Of The Pearl-Ashmore Aquifer, Mchenry County, Il, Usa, Drew C. Carlock, David H. Malone, Jason F. Thomason, Eric Wade Peterson

Eric Wade Peterson

Quaternary glacial till, outwash, lake sediments, and loess compose the surficial deposits of McHenry County, Illinois. Much of the landscape of McHenry County were formed by at least three separate advances of the Harvard Sublobe of the Wisconsin Episode Lake Michigan Lobe, which was part of the Laurentide Ice Sheet. This project focuses on the delineation of the stratigraphy and extent of the Pearl-Ashmore Aquifer. The Pearl-Ashmore Aquifer is the combination of the proglacial outwash of the Wisconsin Episode Ashmore Tongue of the Henry Formation and the youngest outwash associated with the Illinois Episode, which is the Pearl Formation.

Human–Wildlife Conflict And Coexistence, Philip J. Nyhus Dec 2015

Human–Wildlife Conflict And Coexistence, Philip J. Nyhus

Philip J. Nyhus

Human interactions with wildlife are a defining experience of human existence. These interactions can be positive or negative. People compete with wildlife for food and resources, and have eradicated dangerous species; co-opted and domesticated valuable species; and applied a wide range of social, behavioral, and technical approaches to reduce negative interactions with wildlife. This conflict has led to the extinction and reduction of numerous species and uncountable human deaths and economic losses. Recent advances in our understanding of conflict have led to a growing number of positive conservation and coexistence outcomes. I summarize and synthesize factors that contribute to conflict, …

Nicholas Whiting

Many existing and emerging techniques of interrogating metabolism in brain cancer are at an early stage of development. A few clinical trials that employ these techniques are in progress in patients with brain cancer to establish the clinical efficacy of these techniques. It is likely that in vivo metabolomics and metabolic imaging is the next frontier in brain cancer diagnosis and assessing therapeutic efficacy.

Shrinkage Estimation For Multivariate Hidden Markov Mixture Models, Mark Fiecas, Jürgen Franke, Rainer Von Sachs, Joseph Tadjuidje Dec 2015

Shrinkage Estimation For Multivariate Hidden Markov Mixture Models, Mark Fiecas, Jürgen Franke, Rainer Von Sachs, Joseph Tadjuidje

Mark Fiecas

Motivated from a changing market environment over time, we consider high-dimensional data such as financial returns, generated by a hidden Markov model which allows for switching between different regimes or states. To get more stable estimates of the covariance matrices of the different states, potentially driven by a number of observations which is small compared to the dimension, we apply shrinkage and combine it with an EM-type algorithm. This approach will yield better estimates a more stable estimates of the covariance matrix, which allows for improved reconstruction of the hidden Markov chain. In addition to a simulation study and the …
