A sharp lower bound for the least eigenvalue of the signless Laplacian of a non-bipartite graph [PDF]
, 2008 We prove that the minimum value of the least eigenvalue of the signless Laplacian of a connected non-bipartite graph with a prescribed number of vertices is attained solely in the unicyclic graph obtained from a triangle by attaching a path at one of its

Probabilistic and Geometric Languages in the Context of the Principle of Least Action [PDF]
, 2012 This paper explores the question of the unification of the three basic languages of physics, the geometric language of forces, the geometric language of fields or 4-dimensional space-time, and the probabilistic language of quantum mechanics.

Further results on the least eigenvalue of connected graphs [PDF]
, 2011 In this paper, we identify within connected graphs of order n and size n+k (with 0⩽k⩽4 and n⩾k+5) the graphs whose least eigenvalue is minimal.

Keeping Pace or Falling Behind? The Depth of Latin American Trade Agreements
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This article examines whether Latin American countries are keeping pace with global trends in trade agreement depth or falling behind. Using 681 agreements (1970–2019), we develop the Depth Index of Trade Agreements (DITA) to weight provisions endogenously through factor analysis based on co‐occurrence patterns.

Optimal design of a bar with an attached mass for maximizing the heat transfer
Electronic Journal of Differential Equations, 2012 We maximize, with respect to the cross sectional area, the rate of heat transfer through a bar of given mass. The bar serves as an extended surface to enhance the heat transfer surface of a larger heated known mass to which the bar is attached.

The vertex (edge) independence number, vertex (edge) cover number and the least eigenvalue of a graph [PDF]
, 2010 In this paper we characterize the unique graph whose least eigenvalue attains the minimum among all graphs of a fixed order and a given vertex (edge) independence number or vertex (edge) cover number, and get some bounds for the vertex (edge ...
