Nano-Newton electrostatic force actuators for femto-Newton-sensitive measurements: System performance test in the LISA Pathfinder mission
No full textLISA Pathfinder Collaboration: et al.Electrostatic force actuation is a key component of the system of geodesic reference test masses (TM) for the LISA orbiting gravitational wave observatory and in particular for performance at low frequencies, below 1 mHz, where the observatory sensitivity is limited by stray force noise. The system needs to apply forces of order 10−9 N while limiting fluctuations in the measurement band to levels approaching 10−15 N/Hz1/2. We present here the LISA actuation system design, based on audio-frequency voltage carrier signals, and results of its in-flight performance test with the LISA Pathfinder test mission. In LISA, TM force actuation is used to align the otherwise free-falling TM to the spacecraft-mounted optical metrology system, without any forcing along the critical gravitational wave-sensitive interferometry axes. In LISA Pathfinder, on the other hand, the actuation was used also to stabilize the TM along the critical axis joining the two TM, with the commanded actuation force entering directly into the mission’s main differential acceleration science observable. The mission allowed demonstration of the full compatibility of the electrostatic actuation system with the LISA observatory requirements, including dedicated measurement campaigns to amplify, isolate, and quantify the two main force noise contributions from the actuation system, from actuator gain noise and from low frequency “in band” voltage fluctuations. These campaigns have shown actuation force noise to be a relevant, but not dominant, noise source in LISA Pathfinder and have allowed performance projections for the conditions expected in the LISA mission.This work has been made possible by the LISA Pathfinder mission, which is part of the space-science program of the European Space Agency.

Public Health Task Force Report 5.0
No full textOVERVIEW
As of early 2020, humanity has been confronting a pandemic of severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2), which causes coronavirus disease, hereafter referred to as COVID-19.
This virus appears to be a new human pathogen that emerged in 2019 and rapidly spread around
the globe. COVID-19 has affected millions of people, triggering unexpected changes within social
systems, healthcare, and the global economy. Several countermeasures have been implemented
to control the spread of COVID-19, from campaigns aimed to improve personal hygiene practices to
community approaches like social distancing and quarantines.
In late May 2020, UTSA President Taylor Eighmy established a Public Health Task Force, composed
of experts and stakeholders from across the University, to advise on our response to the COVID-19
pandemic. This group was charged with gathering input from an external Expert Advisory Group on
appropriate best practices for relevant topic areas, including protection and prevention policies
associated with health considerations, facilities, and student life. A copy of the original Task Force
Charge is available in Appendix A. An updated charge, issued in March 2021, is available in Appendix
E. Based on an exchange with experts as well as research conducted by members, the Task Force
has developed this overarching guidance document with recommendations for the campus
community as we move through planning and implementation for a phased reopening. This is the fifth
report of the Task Force, primarily focused on operations for Fall 2021.
The results of this report serve as guidance for the Recovery Operations Committee (ROC) that
was formed to implement the recommendations of the Public Health Task Force and Tactical Teams
(see Appendix D).
This UTSA Public Health Task Force reflects one of several groups working together to take public
health best practices into account as we plan to move forward with the highest level of safety and
consideration of our campus community. The University and the Public Health Task Force have
continuously integrated input from many organizations, including but not limited to the U.S. Centers
for Disease Control and Prevention (CDC), the Texas Higher Education Coordinating Board (THECB),
The University of Texas System (UT System), the Governor’s Office, the National Collegiate Athletics
Association (NCAA), the San Antonio Metropolitan Health District (Metro Health), and others as
relevant to this topic. All input has been woven into recommendations here to guide our campus
reopening and operational efforts for Fall 2021 and beyond.
We will continue to update this report as additional guidance is made public and more is learned
about this novel virus’s spread and impact to San Antonio, including direct risk to our campus
community

“You’re tearing me apart, Lisa!” – The force needed for Lisa to pull off Johnny’s arm (from the movie The Room)
No full textIn the 2003 cult classic American drama The Room, during an argument between the two leads Johnny and Lisa, Johnny says “you’re tearing me apart, Lisa!” This paper investigates the force required by Lisa to literally detach Johnny’s arm from his body. The ultimate tensile strength of the glenoid labrum (the weakest segment of the arm, where it meets the shoulder) was found to be 6390000 Nm-2, and the cross-sectional area of Johnny’s arm was determined to be 3.14x10-4 m2. This allowed the force to be calculated as 2006.46 N. It was concluded that it would not be possible for Lisa to detach Johnny’s arm, with her maximum pulling force being 614.49 N (31 % of the actual force needed).
