Microstructure versus Size: Mechanical Properties of Electroplated Single Crystalline Cu Nanopillars
We report results of uniaxial compression experiments on single-crystalline Cu nanopillars with nonzero initial dislocation densities produced without focused ion beam (FIB). Remarkably, we find the same power-law size-driven strengthening as FIB-fabricated face-centered cubic micropillars. TEM analysis reveals that initial dislocation density in our FIB-less pillars and those produced by FIB are on the order of 10^(14)  m^(-2) suggesting that mechanical response of nanoscale crystals is a stronger function of initial microstructure than of size regardless of fabrication method

Comment on “Effects of focused ion beam milling on the nanomechanical behavior of a molybdenum-alloy single crystal” Appl. Phys. Lett. 91, 111915 (2007)
While this article provides insight into differences in mechanics between Ga+-irradiated and “pure” surfaces of molybdenum, there are several statements that are either inaccurate or poorly stated. It is clear that when a surface is directly irradiated by orthogonal ion beam (0.07–0.21 mW), a focused ion beam (FIB) damage layer will likely form and affect the strength. However, this finding does not provide adequate foundation for raising the question of FIB-induced hardening in nanopillars, given the vast differences between these experiments and procedure used in pillar fabrication. These issues would cause considerable confusion and result in disservice to mechanical testing community if not clarified
CONNECTING THE DOTS OF AN OPAQUE CRIME: ANALYZING THE INFORMATION-SHARING FRAMEWORK AND PRACTICES OF CALIFORNIA’S HUMAN-TRAFFICKING TASK FORCES
This thesis explores existing frameworks and common challenges with information sharing among California’s anti–human trafficking specialty units. This research aimed to contextualize current gaps and barriers in the collection and dissemination process of sensitive and confidential human-trafficking information. The research identified social, economic, and human interpersonal factors affecting group work and illustrated how a nuanced application of the social identity analytical method might decrease interpersonal misunderstandings and miscommunications, thus increasing the volume and quantity of anti-trafficking information sharing. The findings of this research indicate that when anti-trafficking specialty units do not work together seamlessly, they foster programmatic and societal shadows that traffickers rely on to exploit their victims. Gaining an in-depth perspective on working group members’ social identities will increase trust within the groups, thereby promoting cooperation, coordination, and collaboration. Elevating all forms of group work is likely to spur analytical insights into the evolving tactics, techniques, and procedures of the threat actors, not to mention identify previously unrecognized victims while building more successful prosecutions.Civilian, California Governor's Office of Emergency Services (CalOES)Approved for public release.
