Max-plus linear inverse problems
James Hook
Oct 15, 2019

In this paper we present new theory and algorithms for 2-norm regression over the max-plus semiring. As an application we also show how max-plus 2-norm regression can be used in system identification of max-plus linear...

Max-Plus Algebraic Statistical Leverage Scores
James Hook
Nov 16, 2017
The statistical leverage scores of a matrix A ∈ Rn×d record the degree of alignment between col(A) and the coordinate axes in Rn. These scores are used in random sampling algorithms for solving certain numerical linear algebra...

Bulk and Surface Chemistry of the Niobium MAX and MXene Phases from Multinuclear Solid-State NMR Spectroscopy.
MXenes, derived from layered MAX phases, are a class of two-dimensional materials with emerging applications in energy storage, electronics, catalysis, and other fields due to their high surface areas, metallic conductivity...
Incomplete LU Preconditioner Based on Max-Plus Approximation of LU Factorization
We present a new method for the a priori approximation of the orders of magnitude of the entries in the LU factors of a complex or real matrix A. This approximation is used to determine the positions of the largest entries in...

Extreme Min – Cut Max – Flow Algorithm
In this article, the authors propose a maximum flow algorithm based on flow matrix. The algorithm only requires the effort to reduce the capacity of the underutilized arcs to that of the respective flow. The optimality of the...
The effects of negative reputational contagion on international airlines

The Boeing 737-MAX was created for the ultra-competitive environment of the aviation industry and advertised as capable of delivering an 8% reduction in fuel and a 14% reduction in CO2 when compared to the...

Macro-porous Ti2AlC MAX-phase ceramics by the foam replication method
Chris Bowen, T. Thomas
Nov 01, 2015
This paper describes the fabrication of porous Ti2AlC MAX-phase ceramics using the foam replication technique. The influence of heat-treatment cycle and sintering time on phase composition, microstructure and type of defect is...

Mixed halide perovskites for spectrally stable and high-efficiency blue light-emitting diodes.
Bright and efficient blue emission is key to further development of metal halide perovskite light-emitting diodes. Although modifying bromide/chloride composition is straightforward to achieve blue emission, practical...
Cross-Currents
Isobel Maddison
Nov 05, 2018
When Elizabeth von Arnim's novel 'Introduction to Sally' appeared in 1926, the critical response was divided. Dame Ethel Smyth may have told von Arnim the book was her 'masterpiece' but some were less convinced; the reviewer in...
Guilt through association

The unfortunate set of circumstances surrounding the loss of both Lion Air Flight 610 and Ethiopian Airlines Flight 302 led to the immediate grounding of the advertised ‘incredibly fuel-efficient’ Boeing 737-MAX. The...

Inclusion Must Be Inferred by the Reader When Digitalizing Elementary Schools
Josefine Karlsson

Digital tools shift pedagogical dimensions which have consequences for education with learning opportunities and sense of belonging for all students. Digital teaching tools have possibilities to adapt to students' needs and...
Macrophages control the retention and trafficking of B lymphocytes in the splenic marginal zone
The marginal zone of the spleen is a precisely ordered region that contains specialized subsets of B lymphocytes and macrophages. Disruption of the negative signaling inositol phosphatase, SH2-containing inositol-5-phosphatase 1...

Repair and stabilization in confined nanoscale systems
Repair is ubiquitous in biological systems, but rare in the inorganic world. We show that inorganic nanoscale systems can however possess remarkable repair and reconfiguring capabilities when subjected to extreme confinement....
The Public Sector Cloud Service Procurement in Sweden
This paper investigates the use of cloud services in the public sector and management of information security challenges in the procurement of such services. The findings are based on an exploratory approach that included a...

The Max-Min Group Contest
We investigate a group all-pay auction in which each group's effort is represented by the minimum among the effort levels exerted by the group members and the prize is a group-specific public good. We fully characterize the...
