Intercomparison of Small Unmanned Aircraft System (sUAS) Measurements for Atmospheric Science during the LAPSE-RATE Campaign.

Small unmanned aircraft systems (sUAS) are rapidly transforming atmospheric research. With the advancement of the development and application of these systems, improving knowledge of best practices for accurate measurement is critical for achieving scientific goals. We present results from an intercomparison of atmospheric measurement data from the Lower Atmospheric Process Studies at Elevation-a Remotely piloted Aircraft Team Experiment (LAPSE-RATE) field campaign. We evaluate a total of 38 individual sUAS with 23 unique sensor and platform configurations using a meteorological tower for reference measurements. We assess precision, bias, and time response of sUAS measurements of temperature, humidity, pressure, wind speed, and wind direction. Most sUAS measurements show broad agreement with the reference, particularly temperature and wind speed, with mean value differences of 1.6 ± 2 . 6 ∘ C and 0.22 ± 0 . 59 m/s for all sUAS, respectively. sUAS platform and sensor configurations were found to contribute significantly to measurement accuracy. Sensor configurations, which included proper aspiration and radiation shielding of sensors, were found to provide the most accurate thermodynamic measurements (temperature and relative humidity), whereas sonic anemometers on multirotor platforms provided the most accurate wind measurements (horizontal speed and direction). We contribute both a characterization and assessment of sUAS for measuring atmospheric parameters, and identify important challenges and opportunities for improving scientific measurements with sUAS.

Self-Restricted Diet in Pediatric Autism Leading to Vitamin A Deficiency and Severe Photophobia.

In developed countries, vitamin A deficiency (VAD) remains rare but is a leading cause of global blindness. We describe the case of a 10-year-old girl with autism spectrum disorder (ASD) initially presenting mild VAD symptoms, escalating to severe photophobia and reluctance to leave a darkened room due to a self-restricted diet of fast-food french fries. A timely examination revealed severe VAD and vitamin A supplementation resolved her symptoms in three weeks. This case highlights the challenge of obtaining accurate patient history in ASD, emphasizing the need for routine dietary discussions and micronutrient testing, especially at ages nine and 13 when the United States Department of Agriculture (USDA) recommends increased vitamin A intake. Early intervention can prevent micronutrient deficiencies in pediatric patients, particularly those with ASD.

Unusual Presentation of Coxsackievirus B and Methicillin-Sensitive Staphylococcus aureus Cellulitis Causing Sepsis.

The clinical association between Coxsackievirus B (CVB) and methicillin-sensitive Staphylococcus aureus (MSSA) has not been well established in the current literature. Here, we report a case of a 29-year-old male who presented with fever and malaise 24 hours after noticing a pruritic lesion on the anterior foreleg that resembled a mosquito bite. After multiple ED visits, laboratory studies, and imaging tests, the patient was admitted for treatment of high fevers and pancytopenia. The final diagnosis was viral sepsis complicated by co-infection with MSSA.
