Dizhen xuebao我国地震地电场观测时的漏电干扰问题会影响到观测质量和地震监测效能。针对这一实际问题，本文提出了点源干扰源定位方法。该方法首先建立地表点源对地电场观测影响模型，根据模型计算点源对地电场观测的干扰幅度，然后求解干扰源相对于中心电极的位置。将定位方法应用于高邮地震台和汉王地震台实际干扰源排查工作中，定位结果与实际干扰源位置基本一致，测区外干扰源定位误差小于2%，测区内干扰源定位误差小于20 m，并对影响计算误差的因素进行了分析。两个台站的实际应用表明 ...

Signal from noise retrieval from one and two-point Green's function - comparison
, 2015 We compare two methods of eigen-inference from large sets of data, based on the analysis of one-point and two-point Green's functions, respectively. Our analysis points at the superiority of eigen-inference based on one-point Green's function. First, the

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

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 ...

The streamline-diffusion method for a convection–diffusion problem with a point source
Journal of Computational and Applied Mathematics, 2003 The authors study a singularly perturbed convection-diffusion problem with a point source. This problem is solved by applying the streamline-diffusion finite element method to a class of Shishkin-type meshes. This approach enables the authors to prove pointwise error estimates, as well as the existence of superconvergent points for the first derivative.
