Polynomial‐shaped electrodes for adaptive X‐ray optics

open access: yesJournal of Synchrotron Radiation, EarlyView.
A shaped electrode design for lithium niobate adaptive X‐ray mirrors connects actuator degrees of freedom to specific polynomial orders, enabling general shape control and the correction of defocus, coma and fourth‐order aberrations with a limited number of inputs.For adaptive mirrors on X‐ray beamlines and optical systems, we describe a strategy for ...

From analytical to data‐driven: multi‐method optimization of a bendable mirror system for dynamic focusing

open access: yesJournal of Synchrotron Radiation, EarlyView.
A small‐radius‐of‐curvature bendable mirror system is developed for dynamic focusing in X‐ray free‐electron laser and synchrotron radiation beamlines, and a transfer‐learning neural‐network and differential‐evolution framework is used for force‐to‐shape modeling and inverse optimization.

Value in the ‘valley of the shadow of death’—When the user is no longer the value arbiter

open access: yesAustralian Journal of Public Administration, EarlyView.
Abstract The Public Service Logic (PSL) user‐centric perspective on value creation has been one of its main critiques. Scholars argue that for some real‐world applications, such as emergency services, where users cannot engage with service offerings, the PSL must consider the roles of other service actors beyond just facilitators.

Sino‐Mexican Encounters Before the ‘Diplomatic Opening’: Exhibition Diplomacy and Grassroots Friendship in the 1960s

open access: yesHistory, EarlyView.
Abstract During the 1960s, Mexico's Institutional Revolutionary Party (PRI) embraced Chinese overtures for a commercial opening as consistent with its anti‐imperialist posture, thereby foreshadowing the diplomatic opening to China in 1972. Yet this professed ideological pluralism was eclipsed by an underlying allegiance to the United States' anti ...
