Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

Dizhen xuebao, 2019 为了进一步探查汉中盆地的深部动力学机制和孕震构造特征，本文基于背景噪声成像、多频接收函数和面波联合反演以及莫霍面Ps震相时深转换方法反演了汉中盆地及其邻区的地壳S波速度和厚度，并进一步对比分析了研究区深部结构与地震活动性之间的关系。结果表明：汉中盆地不同区域的浅表沉积厚度和速度存在差异；部分区域莫霍面处的速度变化平缓，Ps震相与P震相的振幅比＜0.2；汉中盆地内部鲜有地震发生，其周边10 km范围内地震分布主要受到断层控制；4—16 km震源深度上下界面大致对应于低速体底层和高速体顶层 ...

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...

Dizhen xuebao, 2018 收集了鄂尔多斯地块西缘的21个宁夏区域地震台网台站和183个中国地震科学探测台阵台站记录到的2015年1月至2016年1月期间的远震P波资料，通过对其进行反褶积提取接收函数，并利用H-Kappa叠加方法计算了研究区内的莫霍面深度和泊松比。结果表明：研究区的莫霍面深度在36—58 km范围内变化，大体呈南厚北薄、西厚东薄的特点，且具有明显的分区特征，即以香山—天景山断裂为界，莫霍面在南北向呈现明显的起伏变化，该断裂以南的地壳增厚方式可能与青藏高原的水平挤压力所导致的上地壳重叠有关 ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Automatic Receiver Function Picking Using Fuzzy C‐Means Clustering
Earth and Space ScienceComputing receiver function (RF) from teleseismic records can be affected by noise present in the seismic waveforms, and therefore, visual inspection is still preferred for quality control purposes.
