Cybersecurity and research are not a dichotomy: : How to form a productive operational relationship between research computing and data support teams and information security teams

Description
Cybersecurity and research do not have to be opposed to each other. With increasing cyberattacks, it is more important than ever for cybersecurity and research to corporate.

Cybersecurity and research do not have to be opposed to each other. With increasing cyberattacks, it is more important than ever for cybersecurity and research to corporate. The authors describe how Research Liaisons and Information Assurance: Michigan Medicine (IA:MM) collaborate at Michigan Medicine, an academic medical center subject to strict HIPAA controls and frequent risk assess- ments. IA:MM provides its own Liaison to work with the Research Liaisons to better understand security process and guide researchers through the process. IA:MM has developed formal risk decision processes and informal engagements with the CISO to provide risk- based cybersecurity instead of controls-based. This collaboration has helped develop mitigating procedures for researchers when standard controls are not feasible.

In-process laser heating: A cost-efficient way to improve mechanical and geometrical properties for fused filament fabrication

Description

In-process laser heating technique delivers a cost-efficient way to improve mechanical and geometrical properties to nearly isotropic and extremely smooth, respectively. The technique involves the incorperation of a solid-state laser into a commercial off-the-shelf 3D printer, mechanical system to allow controllable laser allumination on desired surfaces, and a gcode postprocesser…

In-process laser heating technique delivers a cost-efficient way to improve mechanical and geometrical properties to nearly isotropic and extremely smooth, respectively. The technique involves the incorperation of a solid-state laser into a commercial off-the-shelf 3D printer, mechanical system to allow controllable laser allumination on desired surfaces, and a gcode postprocesser to proper control of the mechanical system. This process uses laser for local heating, to enhance mass transfer between boundaries or to enhance surface reflow to smooth surface irregularity, to improve mechanical and geometrical properties. Only less than 3 W of laser power (CO2 laser) was used for high temperature material like PEEK and Ultem; less than 1 W (808nm laser) was found to be sufficient for achieving optimal properties for PLA. This technique has the potential for after-market integration into most commercial FFF 3D printers to achieved nearly isotropic and smooth 3D printed objects with various thermoplastic polymers.
