Numerical simulation on gust responses of high aspect ratio aircraft

open access: yesKongqi donglixue xuebao
The bending moment and torque of a high aspect ratio (AR) wing are redistributed when encountering gust turbulence, leading to the strong coupling of aerodynamics and structural dynamics. Affected by gust encounter, the original attitude and stability of

Configurations in fractals [PDF]

open access: yesRocky Mountain Journal of Mathematics, 2021
We define the manifold of configurations to be the quotient set of $k$ points in Euclidean space identified under congruence, and prove that compact subsets of $\mathbb{R}^d, d \geq 2$, of large Hausdorff dimension have a non-null set of configurations in them.

Irreducibility of configurations

open access: yesArs Mathematica Contemporanea, 2015
In a paper from 1886, Martinetti enumerated small $v_3$-configurations. One of his tools was a construction that permits to produce a $(v+1)_3$-configuration from a $v_3$-configuration. He called configurations that were not constructible in this way irreducible configurations.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Application of an efficient fluid simulation method based on IBM and AMR in complex fluid–structure interaction [PDF]

open access: yesAIP Advances
Currently, the immersed boundary method (IBM) is widely used in fluid–structure interaction simulations. However, due to the fact that the mesh used in IBM is often fixed, when the motion or deformation range of the object is large, it causes significant
