Aerodynamic Modeling and Path Optimization of Wing Docking Process for Fixed-Wing UAVs

open access: yes气体物理
The problem of aerial docking of fixed-wing UAVs restricts the development of the chained-wing UAVs. The aero-dynamic modeling and path planning of the wing docking process of fixed-wing UAVs were investigated. At first, the aerodynamic model of the wing

A rapid optical clearing protocol using 2,2'-thiodiethanol for microscopic observation of fixed mouse brain. [PDF]

open access: yesPLoS ONE, 2015
Elucidation of neural circuit functions requires visualization of the fine structure of neurons in the inner regions of thick brain specimens. However, the tissue penetration depth of laser scanning microscopy is limited by light scattering and/or ...

Claudin‐6 Protein Expression in Atypical Teratoid/Rhabdoid Tumors Is Strongly Enriched in the Molecular Subgroup AT/RT‐TYR

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Claudin‐6 has emerged as a promising immunotherapeutic target, yet protein‐level data in atypical teratoid/rhabdoid tumors (AT/RTs) have been inconsistent. We analyzed 36 well‐characterized AT/RT samples and found membranous claudin‐6 protein expression in 58% of cases, with striking enrichment in the molecular subgroup AT/RT‐TYR (100%) and ...

Estimation and Simultaneous Confidence Bands for Fixed-Effects Panel Data Partially Linear Models

open access: yesMathematics
In this paper, we study the estimation and simultaneous confidence band (SCB) problems for fixed-effects panel data partially linear models. We remove the fixed effects and then obtain estimators for the parametric and nonparametric components, which do ...

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...

Small sample inference for fixed effects from restricted maximum likelihood

open access: yes, 1997
Restricted maximum likelihood (REML) is now well established as a method for estimating the parameters of the general Gaussian linear model with a structured covariance matrix, in particular for mixed linear models. Conventionally, estimates of precision

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Investigation of the Relationship between Economic Growth, Trade Openness and Environmental Pollution: A Review of Selected Countries in the Middle East [PDF]

open access: yesPizhūhishnāmah-i Iqtiṣād-i Inirzhī-i Īrān, 2013
Trade openness, economic growth and environment are known as the major issues in recent decads. We considered the effect of expanding trade and economic growth on environmental quality for 11 country in the Middle East during the period of 1980 to 2010 ...
