Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...

Our country’s system for financing health care cannot be fundamentally reformed without significant compromise by all affected interest groups. Providers must yield on cost containment; consumers must accept restrictions in benefits; personal injury lawyers must tolerate tort reform; employers must pay either higher employee compensation or taxes; and private insurers must change the way they d...

Social scientists often consider multiple empirical models of the same process. When these models are parametric and non-nested, the null hypothesis that two models fit the data equally well is commonly tested using methods introduced by Vuong (Econometrica 57(2):307–333, 1989) and Clarke (Am J Political Sci 45(3):724–744, 2001; J Confl Resolut 47(1):72–93, 2003; Political Anal 15(3):347–363, 2...

Polities di¤er in the extent to which political parties can pre-commit to carry out promised policy actions if they take power. Commitment problems may arise due to a divergence between the ex ante incentives facing national parties that seek to capture control of the legislature and the ex post incentives facing individual legislators, whose interests may be more parochial. We study how di¤ere...

Do political and fiscal decentralization make it easier or harder to control inflation? If high inflation reflects the time inconsistency problem, devolving power might restrict the center’s ability to renege on promises of monetary stability, thus reducing inflation. If inflation results from failure to coordinate on a stabilization plan, devolving power to numerous regional governments should...

EU laws have exerted a powerful influence on research, manufacturing, supply, sale and procurement of the products which national health systems rely. Pre-Brexit, UK was closely involved in policy operation regulations affecting these goods. Since Brexit, ideological polarisation political salience during global pandemic driven rhetoric competitive divergence. However, active divergence to date...

Introduction: The incidence of breast cancer increases with the rate of 1-2% at the world. Radiation therapy is one of the available choices for breast cancer treatment. The single isocentre half-beam block technique is considered as a standard technique to avoid hot and cold spots within the PTV. The major advantage of half beam technique is that the both contralateral breast...
