Space Operations Command (SpOC) is the United States Space Force's space operations, cyber operations, and intelligence field command. It is headquartered at Peterson Space Force Base, Colorado and serves as the U.S. Space Force's service component to United States Space Command. Space Operations Command consists of Space Operations Command West, its mission deltas, and garrison commands.Space Operations Command was established on 1 September 1982 as Space Command (SPACECOM), which was the first dedicated space command in the United States Armed Forces. On 15 November 1985, Space Command was renamed Air Force Space Command (AFSPC or AFSPACECOM) to distinguish it from U.S. Space Command, Naval Space Command, and Army Space Command. On 20 December 2019, following the establishment of the United States Space Force as an independent service, Air Force Space Command was also redesignated as United States Space Force (USSF) and served as the transitional headquarters of the new service, but remained a component of the U.S. Air Force. On 21 October 2020, United States Space Force was redesignated as Space Operations Command and officially transitioned from a U.S. Air Force major command to a U.S. Space Force field command.S.S.

Scaling agile and DevSecOps to large enterprise systems such as automotive manufacturing or space-based communication systems offers many challenges. These systems are typically composed of multiple interconnected systems and subsystems, each developed and maintained by multiple vendors operating on different timelines and priorities. The challenge to the acquisition professional is how to manage the agile development process to ensure that all components are developed as a system of systems and not as independent and isolated entities. Multiple vendors, differing timelines, delays in releases, changing requirements, the availability of reliable supply chains, and various internal and external dependencies will need to be considered. This chapter discusses the unique challenges and offers recommended strategies in scaling agile and DevSecOps to large enterprise systems with a particular focus on software-based systems. Where appropriate, reference to hardware-only or hybrid hardware- and software-based systems will also be noted.
Recent work demonstrates that convolutional neural networks can be trained to recognize artificial satellites from spatially unresolved ground-based observations (SpectraNet). SpectraNet enables space domain awareness (SDA) catalogs to be enriched with object identity, a critical source of information for space domain stakeholders. As learned spectral SDA matures, conditions for training and deploying performant and calibrated neural network recognition algorithms must be measured. In this work we present a simulated three year baseline of observations using a longslit spectrograph on a single telescope. We use this dataset to develop a framework for measuring baseline data requirements for performant SpectraNet models, and for testing the performance of those models after deployment. On this limited (single telescope, longslit spectrograph) setup, the presented framework returns a performant model after three weeks of collections. Further, we find that a model can be deployed for a full annual cycle after twenty six weeks of data collection, and the model reaches maximum sustained inference performance after a year. Thus a SpectraNet powered longslit spectrograph can provide tactical inferences after a few weeks and be retrained to infer through seasonal variability during deployment. We find that the simulated system and dataset regularly exceed 82% classification accuracy, and discuss performance improvements with enhanced instrumentation and/or multi-telescope networks.
Introduction: Similar to prior reviews, the Journal of Wellness editors searched the literature from the second half of 2022 for an interesting and impactful selection of publications on wellness in healthcare professionals. Methods: Editors conducted a standard keyword search in Pubmed, focusing chiefly on large journals, interventional trials, and other prospective research. We included papers published between July 1, 2022 and December 31, 2022. Literature in Review: Finding several hundred publications, we excluded editorials, reviews, and some smaller, less generalizable papers. A final 25 significant studies focusing on wellness in medical professionals were sorted into the following categories: logistics, creativity / arts, exercise and nutrition, curriculum / training, burnout, and miscellaneous. Conclusion: JWellness editors continue to appreciate and focus on research related to thriving and positive well-being, rather than descriptive burnout studies.
No abstract available. Editor’s note: We published the first half of this biographical piece in our Spring 2022 issue (Volume 9: Number 1) at URL: https://jcldusafa.org/index.php/jcld/issue/view/1. The author highlights several themes that emerge from Davis’s experience as a leader, including turning challenges into opportunities, focusing on unit morale and culture, and winning over detractors through humility and demonstrating competence. The story picks up with his elevation to command of the 332nd Fighter Group.
Objective: An acute respiratory infection of unknown origin was first detected in Wuhan, China, and reported to the WHO on December 31, 2019, and within a month, this outbreak was declared as a Public Health Emergency of International Concern. This study was carried out with an objective to assess the spectrum of clinical presentations and host-related factors in outcome of COVID-19 during the first wave. Methods: This study was a retrospective observational study on 427 laboratory conformed COVID-19 cases at tertiary care center in North India during 6 months of the first wave. The demographic data, clinical profiles, comorbid conditions, treatment given, duration of hospital stay, and outcome were collected on a predesigned pro forma by the investigator himself and entered a Microsoft Excel sheet and analyzed using SPSS version 17.0 software. Results: Mean age of the study participants was 48.70 years. Majority (34.89%) belonged to above 60 years. About 74% were male. Mean duration of symptoms before detection was 1.30 and mean duration of hospital stay was 11.98 days. Majority had fever (73.54%) followed by myalgia (49.88%). About 85.48% had more than 3 symptoms and 69.32 had symptoms for less than 3 days before getting detected. About 40.52% had comorbidities and only 14.05% had history of contact with COVID confirmed case. Only 8.2% were asymptomatic while 23.19% had severe symptoms. Majority 91.57% were admitted to hospital while only 8.43% were put under home isolation. About 74% were positive on rapid antigen test (RAT) while 29.51% needed RT PCR test to turn positive. About 28.1% had bilateral pneumonia on chest X-ray findings. About 6.3% of were pregnant ladies. The overall mortality rate of our hospital during that 6-month period was 4.69%. Out of all parameters, only age category was statistically significant associated with outcome on discharge while other variables such as comorbidity, symptom duration, and severity of disease during admission did not show any statistically significant association. Conclusion: This single-center study provided the spectrum of clinical presentations and host-related factors in outcome of COVID-19 during the first wave which may help in decrease the burden of disease, minimize social disruption, and reduce the economic impact associated with a pandemic. Early detection, admission, and treatment of individuals with comorbidities and elderly would increase the recovery from the disease, thereby reduce mortality.
