Factors and Connected Factors in Tough Graphs with High Isolated Toughness
, 2019 In this paper, we show that every $1$-tough graph with order and isolated toughness at least $r+1$ has a factor whose degrees are $r$, except for at most one vertex with degree $r+1$.

Did U.S. Bank Supervisors Get Tougher During the Credit Crunch? Did They Get Easier During the Banking Boom? Did It Matter to Bank Lending? [PDF]
We test three hypotheses regarding changes in supervisory toughness' and their effects on bank lending. The data provide modest support for all three hypotheses that there was an increase in toughness during the credit crunch period (1989-1992), that ...

, 1996 We present a systematic study of the effect of crack blunting on subsequent crack propagation and dislocation emission. We show that the stress intensity factor required to propagate the crack is increased as the crack is blunted by up to thirteen atomic

A parametric study of fracture toughness of fibrous composite materials [PDF]
Impacts to fibrous composite laminates by objects with low velocities can break fibers giving crack-like damage. The damage may not extend completely through a thick laminate.

The Arizona Summit: Tough Times in a Tough Land
, 2010 Western repositories have much to gain and little to lose from statewide initiatives that promote cooperative collection management policies. The region's topography, demographics, boom-bust cycles, and flood of new residents threaten their missions and their very existence.

Advanced Functional Materials, EarlyView.The coherent heterostructure and the strong stress field at the heterointerface upshift the d‐band center of vanadium toward the Fermi level, which effectively lowers the Na+ diffusion barrier, facilitates charge transfer and accelerates reaction kinetics.
