The numerical solution to the frequency equation for the transverse vibration of a simple beam with symmetric overhang is found. The numerical results converge to the analytical solutions for the two limiting cases of a beam with no overhang and a beam with no span and agree with the case in which the supports are at the nodal points of a freely vibrating beam. An approximation to the solution ...

RNase III Drosha initiates microRNA (miRNA) maturation by cleaving a primary miRNA transcript and releasing a pre-miRNA with a 2 nt 3' overhang. Dicer recognizes the 2 nt 3' overhang structure to selectively process pre-miRNAs. Here, we find that, unlike prototypic pre-miRNAs (group I), group II pre-miRNAs acquire a shorter (1 nt) 3' overhang from Drosha processing and therefore require a 3'-en...

The MER3 protein of Saccharomyces cerevisiae is required for crossover in meiosis and has been suggested to act at the initiation of homologous pairing and the resolution of Holliday junctions. The purified MER3 protein is a DNA helicase that translocates along single-stranded DNA in the 3' to 5' direction displacing annealed DNA fragments. Here, MER3 was found to be able to unwind various doub...

The rotor overhang is used to enhance the air-gap flux and improve the power density. Due to the asymmetry in the axial direction caused by the overhang, a time consuming 3D analysis is necessary when designing a motor with overhang. To solve this problem, this paper proposes an equivalent magnetic circuit model (EMCM) which takes account overhang effects without a 3D analysis by using effectiv...

We present an approach for controlling the undercut and the minimal overhang angle in density based topology optimization, which are useful for reducing support structures in additive manufacturing. We cast both the undercut control and the minimal overhang angle control that are inherently constraints on the boundary shape into a domain integral of Heaviside projected density gradient. Such a ...

There is a natural bijection between Dyck paths and basis diagrams of the Temperley-Lieb algebra defined via tiling. Overhang paths are certain generalisations of Dyck paths allowing more general steps but restricted to a rectangle in the twodimensional integer lattice. We show that there is a natural bijection, extending the above tiling construction, between overhang paths and basis diagrams ...

This paper studies the optimal compensation problem between shareholders and the agent in the Leland (1994) capital structure model, and finds that the debt-overhang effect on the endogenous managerial incentives lowers the optimal leverage. Consistent with data, our model delivers a negative relation between pay-performance sensitivity and firm size, and the interaction between debt-overhang a...

We analyze government interventions to recapitalize a banking sector that restricts lending to firms because of debt overhang. We find that the efficient recapitalization program injects capital against preferred stock plus warrants and conditions implementation on sufficient bank participation. Preferred stock plus warrants reduces opportunistic participation by banks that do not require recap...

We demonstrate the impact of macroeconomic risk on the investment decisions of firms with risky debt and the costs of debt overhang. Debt overhang stems from the transfer between equity holders and debt holders after investment is made. The cyclicality of a firm’s assets in place and its growth options affects when such transfers are likely to occur and how much they can be, which provides a ra...
