Wake flow visualization of a dandelion pappus with posture change
Journal of Fluid Science and Technology, 2023 A typical plant that is distributed by wind is the dandelion, which possesses a complex hairy pappus that aids in flying. A pappus or group of bristly filaments found in plumed seeds is believed to have a role in drag enhancement. The pappus prolongs the

Orexin and MCH neurons: regulators of sleep and metabolism
Frontiers in Neuroscience, 2023 Sleep-wake and fasting-feeding are tightly coupled behavioral states that require coordination between several brain regions. The mammalian lateral hypothalamus (LH) is a functionally and anatomically complex brain region harboring heterogeneous cell ...

Signature of a Cosmic String Wake at $z=3$
, 2020 In this paper, we describe the results of N-body simulation runs, which include a cosmic string wake of tension $G\mu= 4 \times 10^{-8}$ on top of the usual $\Lambda CDM$ fluctuations. To obtain a higher resolution of the wake in the simulations compared

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes
Pediatric Blood &Cancer, EarlyView.ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.
