Ethical Considerations In Cosmetic Dentistry

Journal IDA

Dentistry is both an art and a science. Patient care revolves around treatment for pain, missing teeth while also ensuring that appearances or the esthetic outcomes are maintained or enhanced. These two facets are not contradictory, but are intertwined for optimal, complete and customizable care for each patient. Dentists are often faced with requests from patients for a stereotypical “perfect” smile, which includes perfectly aligned teeth that are white in color resembling the image commonly conveyed by the media. As clinicians, we respond in our own way to these increasingly demanding esthetic demands. Some specialize in developing “esthetic” treatments; others …

Letara Ltd. has developed ICR‑X, a 2U CubeSat‑class hybrid chemical propulsion system using HDPE fuel and nitrous oxide. The system features an integrated oxidizer‑tank–combustion‑chamber structure, a low‑power multi‑restart ECP ignition system, and oxidizer‑temperature‑based thrust control, enabling 1–4 …

Scaling Distributed Spacecraft Autonomy Operations With Simple Temporal Networks: Introducing Splinter, Michael Iatauro, Caleb Adams, Caroline Lassiter

Small Satellite Conference

The Absolute Time Sequence (ATS) is a well-established mechanism for high-level spacecraft control, executing commands at specific times. One weakness of ATSs is that the cost of making a change to the command sequence grows with the length of the sequence, and the cost paid is many repetitive-but-detailed changes to the timing of commands, which is error-prone.

This weakness becomes a liability when scaling up to spacecraft swarms or long ATS durations because any perturbation to the command sequence or schedule incurs significant cost. Fitting that cost within a small team or short sequence development timeline becomes a central challenge …

Opengrcrmf: A Vendor-Neutral Framework For Teaching And Modeling Rmf Automation, Continuous Authorization, And Zero Trust Governance, Anand Janjal

Journal of Cybersecurity Education, Research and Practice

Abstract—Federal and regulated organizations continue to rely on document-centric Authorization to Operate (ATO) processes even as the NIST Risk Management Framework (RMF), continuous monitoring guidance, Zero Trust Architecture (ZTA), and continuous authorization initiatives require more continuous, evidence-driven risk management [1]-[3], [13], [15]. Manual System Security Plan (SSP) updates, spreadsheet-based Plan of Action and Milestones (POA&M) tracking, and disconnected assessment evidence create governance latency: the delay between operational security events and authorization-ready governance response. This paper presents OpenGRCRMF, a proposed open, vendor-neutral reference framework that models RMF lifecycle activities as workflow states, treats authorization artifacts as structured governance objects, and …
