Relief Of The Dma1-Mediated Checkpoint Requires Dma1 Autoubiquitination And Dynamic Localization, Christine M. Jones, Jun Song Chen, Alyssa E. Johnson, Zachary C. Elmore, Sierra N. Cullati, Janel R. Beckley, Kathleen L. Gould Sep 2018

Relief Of The Dma1-Mediated Checkpoint Requires Dma1 Autoubiquitination And Dynamic Localization, Christine M. Jones, Jun Song Chen, Alyssa E. Johnson, Zachary C. Elmore, Sierra N. Cullati, Janel R. Beckley, Kathleen L. Gould

Faculty Publications

© 2018 Jones, Chen, et al. Chromosome segregation and cell division are coupled to prevent aneuploidy and cell death. In the fission yeast Schizosaccharomyces pombe, the septation initiation network (SIN) promotes cytokinesis, but upon mitotic checkpoint activation, the SIN is actively inhibited to prevent cytokinesis from occurring before chromosomes have safely segregated. SIN inhibition during the mitotic checkpoint is mediated by the E3 ubiquitin ligase Dma1. Dma1 binds to the CK1-phosphorylated SIN scaffold protein Sid4 at the spindle pole body (SPB), and ubiquitinates it. Sid4 ubiquitination antagonizes the SPB localization of the Polo-like kinase Plo1, the major SIN activator, so …

Pal: Toward A Recommendation System For Manuscripts, Sl Ziegler, Richard Shrake

Faculty Publications

Book-recommendation systems are increasingly common, from Amazon to public library interfaces. However, for archives and special collections, such automated assistance has been rare. This is partly due to the complexity of descriptions (finding aids describing whole collections) and partly due to the complexity of the collections themselves (what is this collection about and how is it related to another collection?). The American Philosophical Society Library is using circulation data collected through the collection-management software package, Aeon, to automate recommendations. In our system, which we’re calling PAL (People Also Liked), recommendations are offered in two ways: based on interests (“You’re interested …

Proximity Ligation Assay To Study Protein-Protein Interactions Of Proteins On Two Different Cells, Rushikesh Sable, Nithya Jambunathan, Sitanshu Singh, Sandeep Pallerla, Konstantin G. Kousoulas, Seetharama Jois

Faculty Publications

© 2018 Future Science. All rights reserved. Protein-protein interactions (PPI) by homo-, hetero- or oligo-merization in the cellular environment regulate cellular processes. PPI can be inhibited by antibodies, small molecules or peptides, and this inhibition has therapeutic value. A recently developed method, the proximity ligation assay (PLA), provides detection of PPI in the cellular environment. However, most applications using this assay are for proteins expressed in the same cell. We employ PLA for the first time to study PPI of cell surface proteins on two different cells. Inhibition of PPI using a peptide inhibitor is also quantified using this assay; …

Variation Across Mitochondrial Gene Trees Provides Evidence For Systematic Error: How Much Gene Tree Variation Is Biological?, E J. Richards, J M. Brown, A J. Barley, R A. Chong, E J. Richards Sep 2018

Variation Across Mitochondrial Gene Trees Provides Evidence For Systematic Error: How Much Gene Tree Variation Is Biological?, E J. Richards, J M. Brown, A J. Barley, R A. Chong, E J. Richards

Faculty Publications

The use of large genomic data sets in phylogenetics has highlighted extensive topological variation across genes. Much of this discordance is assumed to result from biological processes. However, variation among gene trees can also be a consequence of systematic error driven by poor model fit, and the relative importance of biological vs. methodological factors in explaining gene tree variation is a major unresolved question. Using mitochondrial genomes to control for biological causes of gene tree variation, we estimate the extent of gene tree discordance driven by systematic error and employ posterior prediction to highlight the role of model fit in …

Faculty Publications

Summary Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), the sugarcane aphid, is an invasive species in the United States. This species is a threat to crops of economic importance including sorghum and sugar cane. Therefore, monitoring dispersal of this pest is necessary to document its geographic expansion. Based on trap catches obtained from the Midwest Suction Trap Network during 2015 to 2017, sugarcane aphids arrived late in the growing season as far as northern Wisconsin. We will continue to monitor the dispersal of this aphid species through the Midwest Suction Trap Network in order to provide information to researchers, extension agents, and …

Obligate nutritional endosymbioses are arguably the most intimate of all interspecific associations. While many insect nutritional endosymbioses are well studied, a full picture of how two disparate organisms, a bacterial endosymbiont and a eukaryotic host, are integrated is still lacking. The mTOR pathway is known to integrate nutritional conditions with cell growth and survival in eukaryotes. Characterization and localization of amino acid transporters in aphids suggest the mTOR pathway as a point of integration between an aphid host and its amino acid-provisioning endosymbiont Buchnera aphidicola. The mTOR pathway is unannotated in aphids and unstudied in any nutritional endosymbiosis. We annotated …

A Notion Of Minor-Based Matroid Connectivity, Zachary Gershkoff, James Oxley Sep 2018

A Notion Of Minor-Based Matroid Connectivity, Zachary Gershkoff, James Oxley

Faculty Publications

For a matroid N, a matroid M is N-connected if every two elements of M are in an N-minor together. Thus a matroid is connected if and only if it is U1,2-connected. This paper proves that U1,2 is the only connected matroid N such that if M is N-connected with |E(M)|>|E(N)|, then M\e or M/e is N-connected for all elements e. Moreover, we show that U1,2 and M(W2) are the only matroids N such that, whenever a matroid has an N-minor using {e,f} and an N-minor using {f,g}, it also has an N-minor using {e,g}. Finally, we show that …

The CALorimetric Electron Telescope primary detector (CALET-CAL) is a 30 radiation-length-deep hybrid calorimeter designed for the accurate measurement of high-energy cosmic rays. It is capable of triggering on and giving near complete containment of electromagnetic showers from primary electrons and gamma rays from 1 GeV to over 10 TeV. The first 24 months of on-orbit scientific data (2015 November 01-2017 October 31) provide valuable characterization of the performance of the calorimeter based on analyses of the gamma-ray data set in general and bright point sources in particular. We describe the gamma-ray analysis, the expected performance of the calorimeter based on …

Excluding A Large Theta Graph, Guoli Ding, Emily Marshall Sep 2018

Excluding A Large Theta Graph, Guoli Ding, Emily Marshall

Faculty Publications

A theta graph, denoted θa,b,c, is a graph of order a+b+c−1 consisting of a pair of vertices and three internally-disjoint paths between them of lengths a, b, and c. In this paper we study graphs that do not contain a large θa,b,c minor. More specifically, we describe the structure of θ1,2,t-, θ2,2,t-, θ1,t,t-, θ2,t,t-, and θt,t,t-free graphs where t is large. The main result is a characterization of θt,t,t-free graphs for large t. The 3-connected θt,t,t-free graphs are formed by 3-summing graphs without a long path to certain planar graphs. The 2-connected θt,t,t-free graphs are then built up in a …

Calculation Of Quantum Discord In Higher Dimensions For X- And Other Specialized States, A. R.P. Rau Sep 2018

Calculation Of Quantum Discord In Higher Dimensions For X- And Other Specialized States, A. R.P. Rau

Faculty Publications

Quantum discord, a kind of quantum correlation based on entropic measures, is defined as the difference between quantum mutual information and classical correlation in a bipartite system. Procedures are available for analytical calculation of discord when one of the parties is a qubit with dimension two and measurements made on it to get that one-way discord. We extend now to systems when both parties are of larger dimension and of interest to qudit–quDit with d, D≥ 3 or spin chains of spins ≥ 1. While recognizing that no universal scheme is feasible, applicable to all density matrices, nevertheless, a procedure …

Aim: The Indonesian island of Sulawesi is home to thousands of endemic terrestrial animal species. Phylogeographical studies of some of these taxa revealed concordant distribution patterns (areas of endemism; AoEs), suggestive of a shared evolutionary or ecological mechanism driving divergence among various terrestrial taxa. Generally, AoEs have been attributed to Pleistocene marine incursions, geological fault zones and Sulawesi's history as an archipelago. We test, for the first time, the hypothesis that population divergences are associated with unsuitable climate spaces at the boundaries between these areas. Location: Sulawesi, Indonesia. Taxon: Maxomys musschenbroekii, a common murid rodent endemic to Sulawesi. Methods: We …

Horizontal Dispersion Of Buoyant Materials In The Ocean Surface Boundary Layer, Jun Hong Liang, Xiaoliang Wan, Kenneth A. Rose, Peter P. Sullivan, James C. Mcwilliams Sep 2018

Horizontal Dispersion Of Buoyant Materials In The Ocean Surface Boundary Layer, Jun Hong Liang, Xiaoliang Wan, Kenneth A. Rose, Peter P. Sullivan, James C. Mcwilliams

Faculty Publications

The horizontal dispersion of materials with a constant rising speed under the exclusive influence of ocean surface boundary layer (OSBL) flows is investigated using both three-dimensional turbulence-resolving Lagrangian particle trajectories and the classical theory of dispersion in bounded shear currents generalized for buoyant materials. Dispersion in the OSBL is caused by the vertical shear of mean horizontal currents and by the turbulent velocity fluctuations. It reaches a diffusive regime when the equilibrium vertical material distribution is established. Diffusivity from the classical shear dispersion theory agrees reasonably well with that diagnosed using three-dimensional particle trajectories. For weakly buoyant materials that can …

The Mayer And Minimum Time Problems With Stratified State Constraints, C. Hermosilla, P. R. Wolenski, H. Zidani Sep 2018

The Mayer And Minimum Time Problems With Stratified State Constraints, C. Hermosilla, P. R. Wolenski, H. Zidani

Faculty Publications

This paper studies optimal control problems with state constraints by imposing structural assumptions on the constraint domain coupled with a tangential restriction with the dynamics. These assumptions replace pointing or controllability assumptions that are common in the literature, and provide a framework under which feasible boundary trajectories can be analyzed directly. The value functions associated with the state constrained Mayer and minimal time problems are characterized as solutions to a pair of Hamilton-Jacobi inequalities with appropriate boundary conditions. The novel feature of these inequalities lies in the choice of the Hamiltonian.

Investigation Of An Early Season River Flood Pulse: Carbon Cycling In A Subtropical Estuary, Benjamin J. Haywood, John R. White, Robert L. Cook

Faculty Publications

© 2018 Elsevier B.V. The January 2016 Bonnet Carré Spillway (BCS) opening resulted in a large-scale Mississippi River (MR) flood discharge that qualitatively and quantitatively impacted the dissolved organic matter (DOM) cycling in the Lake Pontchartrain Estuary (LPE) located in Louisiana, USA. This early season flood event was a result of the delay of snow formation caused by warmer than normal watershed temperatures. During the diversion period and the subsequent weeks, the LPE water temperature remained lower than pre-flood water temperatures, suppressing carbon cycling. Following that period, the water temperature increased, leading to an increase in the rate of abiotic …

One of the major issues in plant breeding is the occurrence of genotype × environment (GE) interaction. Several models have been created to understand this phenomenon and explore it. In the genomic era, several models were employed to improve selection by using markers and account for GE interaction simultaneously. Some of these models use special genetic covariance matrices. In addition, the scale of multi-environment trials is getting larger, and this increases the computational challenges. In this context, we propose an R package that, in general, allows building GE genomic covariance matrices and fitting linear mixed models, in particular, to a …
