Computing Optimal Discrete Morse Functions
Electronic Notes in Discrete Mathematics, 2004 Abstract The essential structural information of discrete Morse functions is captured by so-called Morse matchings. We show that computing optimal Morse matchings is NP -hard and give an integer programming formulation for the problem. Then we present first polyhedral results for the corresponding polytope and report on some preliminary ...

Visual Demo of Discrete Stratified Morse Theory (Media Exposition)
, 2020 Discrete stratified Morse theory, first introduced by Knudson and Wang, works toward a discrete analogue of Goresky and MacPherson’s stratified Morse theory.

The Morse–Bott inequalities, orientations, and the Thom isomorphism in Morse homology [PDF]
, 2016 The Morse–Bott inequalities relate the topology of a closed manifold to the topology of the critical point set of a Morse–Bott function defined on it. The Morse–Bott inequalities are sometimes stated under incorrect orientation assumptions.

Movement Disorders Clinical Practice, EarlyView.Abstract Background LRRK2‐Parkinson's disease (LRRK2‐PD) is biologically heterogeneous with approximately 30% lacking aggregated alpha synuclein (αSyn) in cerebrospinal fluid by seed amplification assay (SAA). Prior work has suggested slower progression in LRRK2‐PD compared to sporadic PD (sPD).

The Euler Characteristic of the Fiber Product of Morse Functions on Grassmannians
International Journal of Mathematics and Mathematical SciencesFor F=R, C, or H, let GkFn denote the Grassmannian of k-planes in Fn. For a well-known Morse function f:GkFn⟶R, we denote by Cf the fiber product of two copies of f. We prove a formula which describes χCf.

Are Academic Executives Greener? Evidence From China
Managerial and Decision Economics, EarlyView.ABSTRACT This paper investigates the impact of executives with academic backgrounds (“academic executives”) on corporate green patents. We find that both the presence of academic executives and the proportion of academic executives have a significantly positive impact on firms' green patents, and this effect is positively associated with the firm's ...

Public Administration and Development, EarlyView.ABSTRACT Localization is the process of adapting and developing international aid to suit local contexts. Thus, localization involves paying attention to the relations between organizations and local actors receiving development aid. One key question that has not, as yet, been satisfactorily answered is how to collectively organize localization to ...

Advances in High Energy Physics, 2015 The second-order N-dimensional Schrödinger equation with pseudoharmonic potential is reduced to a first-order differential equation by using the Laplace transform approach and exact bound state solutions are obtained using convolution theorem.

Public Administration and Development, EarlyView.ABSTRACT This article explores the management adaptation strategies non‐governmental organizations (NGOs) managers employ in order to operate in repressive political environments. It answers the question: how do NGO managers initiate, manage and sustain internal change when the political/regulatory environment changes?
