Creep properties and constitutive model of diabase in deep water conveyance tunnels
The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.

An overview of harmonic analysis and the shifted wave equation on symmetric graphs [PDF]
Let X be a symmetric graph of type k and order r, where k,r $\ge$ 2 are integers. In this paper we give explicite expressions of the horocyclic Abel transform and its dual, as well as their inverses X.

Mergers and Acquisitions and Brexit: A Natural Experiment
ABSTRACT We study the impact of Brexit uncertainty on one of the most important forms of corporate investment: mergers and acquisitions (M&As). Brexit provides us with an ideal natural experiment to explore the real effects of economic uncertainty and understand the underlying transmission mechanism. We document a significant decline in the number of M&

Nonlinear Shear-free Radiative Collapse
We study realistic models of relativistic radiating stars undergoing gravitational collapse which have vanishing Weyl tensor components. Previous investigations are generalised by retaining the inherent nonlinearity at the boundary.

On simultaneous Abel equations
The system (1) \(\phi [f(x)]=\phi (x)+1\quad \phi [g(x)]=\phi (x)+s\) is investigated, where x ranges over an open interval, and f and g are continuous commuting self-bijections of the interval. One would assume that then f and g are in some sense iterates of each other, and indeed the results are in that general direction.

Interplay Between Green Investment and Market Price Premia in Global Shipping
ABSTRACT Existing research emphasises that the driver of green investment is its future profitability. This paper shows that other investors' decisions also influence green investment. We take the example of scrubber installation in shipping, which is optional by regulation but has an established market for trading its underlying asset.
