    • The Proof is in the Pudding: Building a Local Repository for Online Learning Objects 

      Hale, Jordan; Weaver, Kari D. (Association of College & Research Libraries, 2021)
      Libraries are increasingly building collections of learning materials in electronic formats. As the availability grows, it becomes necessary to consider the long-term discovery, access, management, and local ownership ...
    • Proof of the Kalai-Meshulam conjecture 

      Chudnovsky, Maria; Scott, Alex; Seymour, Paul; Spirkl, Sophie (Springer Nature, 2020-07-01)
      Let G be a graph, and let fG be the sum of (−1)∣A∣, over all stable sets A. If G is a cycle with length divisible by three, then fG = ±2. Motivated by topological considerations, G. Kalai and R. Meshulam [8] made the ...

    • Provocations from #vanlife: Investigating Life and Work in a Community Extensively Using Technology Not Designed for Them 

      Rizvi, Ali Haider; Morayko, Kateryna; Song, Arden; Hancock, Mark (ACM, 2021-05)
      Research on how lived experiences with technology intersect with home and work are core themes within HCI. Prior work has primarily focused on conventional life and work in Western countries. However, the unconventional ...
    • The Psychogeographies of Site-Specific Art 

      MacDonald, Shana (HAL Open Science, 2018-07-16)
      Contemporary efforts at urban revitalization have encouraged an increased production of site-specific public art events that temporarily inhabit popular city hubs. These “pop up†interventions range from loosely assembled ...
    • Psychological Prices at Retail Gasoline Stations: The Policies of 0-, 5-, and 9-Ending Prices 

      Huck, Nicolas; Chenavaz, Regis Y.; Dimitrov, Stanko (Taylor & Francis, 2021-07-12)
      Psychological prices are known to impact consumer behaviour and to depend on retailers’ characteristics. Less understood is last digit pricing, especially in the context of retail gasoline stations. We study price endings ...
    • PtSe2 Field-Effect Transistors: New Opportunities for Electronic Devices 

      AlMutairi, AbdulAziz; Yin, Demin; Yoon, Youngki (Institute of Electrical and Electronics Engineers, 2017-11-15)
      PtSe2, a new family of transition metal dichalcogenides, has been explored for electronic device applications using density functional theory (DFT) and non-equilibrium Green’s function (NEGF) within the third nearest ...
    • Public Willingness to Pay for Water Quality Improvements in the Great Lakes Basin Before and During Covid-19 

      Brouwer, Roy; Dupont, Diane; Pinto, Rute; Huang, Yichun (University of Waterloo, 2023-05-15)
      Economic valuation of water quality improvements is an essential input to inform policy and decision-making towards sustainable watershed management. The economic values provide important insight in the wide variety of ...
    • Pure Pairs VI. Excluding an Ordered Tree. 

      Scott, Alex; Seymour, Paul; Spirkl, Sophie (Society for Industrial and Applied Mathematics Journal on Discrete Mathematics, 2022-01)
      A pure pair in a graph G is a pair (Z1,Z2) of disjoint sets of vertices such that either every vertex in Z1 is adjacent to every vertex in Z2, or there are no edges between Z1 and Z2. With Maria Chudnovsky, we recently ...
    • Pure pairs. I. Trees and linear anticomplete pairs 

      Chudnovsky, Maria; Scott, Alex; Seymour, Paul; Spirkl, Sophie (Elsevier, 2020-12-02)
      The Erdős-Hajnal conjecture asserts that for every graph H there is a constant c > 0 such that every graph G that does not contain H as an induced subgraph has a clique or stable set of cardinality at least |G|c. In this ...
    • Pure pairs. II. Excluding all subdivisions of a graph 

      Chudnovsky, Maria; Scott, Alex; Seymour, Paul; Spirkl, Sophie (Springer Nature, 2021-06-01)
      We prove for every graph H there exists ɛ > 0 such that, for every graph G with |G|≥2, if no induced subgraph of G is a subdivision of H, then either some vertex of G has at least ɛ|G| neighbours, or there are two disjoint ...
    • Pure pairs. III. Sparse graphs with no polynomial-sized anticomplete pairs 

      Chudnovsky, Maria; Fox, Jacob; Scott, Alex; Seymour, Paul; Spirkl, Sophie (Wiley, 2020-11)
      A graph is H-free if it has no induced subgraph isomorphic to H, and |G| denotes the number of vertices of G. A conjecture of Conlon, Sudakov and the second author asserts that: - For every graph H, there exists ∈ > 0 ...
    • Pure pairs. IV. Trees in bipartite graphs. 

      Scott, Alex; Seymour, Paul; Spirkl, Sophie (Elsevier, 2023-07)
      In this paper we investigate the bipartite analogue of the strong Erd˝os-Hajnal property. We prove that for every forest H and every τ with 0 < τ ≤ 1, there exists ε > 0, such that if G has a bipartition (A,B) and does not ...
    • Pure Pairs. IX. Transversal Trees 

      Scott, Alex; Seymour, Paul; Spirkl, Sophie (Society for Industrial and Applied Mathematics, 2024)
      Fix k>0, and let G be a graph, with vertex set partitioned into k subsets ("blocks") of approximately equal size. An induced subgraph of G is "transversal" (with respect to this partition) if it has exactly one vertex in ...
    • Pure Pairs. V. Excluding Some Long Subdivision. 

      Scott, Alex; Seymour, Paul; Spirkl, Sophie (Springer, 2023-06-16)
      A \pure pair" in a graph G is a pair A;B of disjoint subsets of V (G) such that A is complete or anticomplete to B. Jacob Fox showed that for all " > 0, there is a comparability graph G with n vertices, where n is large, ...

      Scott, Alex; Seymour, Paul; Spirkl, Sophie (Elsevier, 2023-07)
      For integer n>0, let f(n) be the number of rows of the largest all-0 or all-1 square submatrix of M, minimized over all n x n 0/1-matrices M. Thus f(n)=O(log n). But let us fix a matrix H, and define fH(n) to be the same, ...
