Current guidelines for implantable cardioverter-defibrillator （ICD） therapy in heart failure patients were established by multiple device Irials; however, very few geriatric patients （patients ≥ 65 years old） were included in these studies. This article explores the controversies of ICD implantation in the geriatric population, management of delivered ICD therapy in this age group, and the end of life care in patients with ICD.

在体育界,拜尔斯、帕吉和布莱德肖的成功故事令人印象深刻,这三名精英运动员都曾经公开谈论心理健康问题。2021年夏天,拜尔斯在东京奥运女子体操团体决赛中途退出,声称自己的心理健康出了问题。今年早些时候,英国女子撑竿跳高运动员布莱德肖担心在追求体育成就过程中身心受损。英国女子蹦床运动员帕吉也透露,她曾深陷“技能丧失综合征”困扰,2016年里约奥运会前尤其感到焦虑。

Originally developed decades ago, the binder jetting additive manufacturing （B J-AM） process possesses various advantages compared to other additive manufacturing （AM） technologies such as broad material compat- ibility and technological expandability. However, the adoption of B J-AM has been limited by the lack of knowledge with the fundamental understanding of the process principles and characteristics, as well as the relatively few systematic design guideline that are available. In this work, the process design considerations for B J-AM in green part fabrication were discussed in detail in order to provide a comprehensive perspective of the design for additive manufacturing for the process. Various process factors, including binder saturation, in- process drying, powder spreading, powder feedstock characteristics, binder characteristics and post-process curing, could significantly affect the printing quality of the green parts such as geometrical accuracy and part integrity. For powder feedstock with low flowability, even though process parameters could be optimized to partially offset the printing feasibility issue, the qualities of the green parts will be intrinsically limited due to the existence of large internal voids that are inaccessible to the binder. In addition, during the process development, the balanced combination between the saturation level and in-process drying is of critical importance in the quality control of the green parts.

A general model of a hybrid inteffacial domain wall （HIDW） in ferromagnetic/antiferromagnetic exchange biased bilayers is proposed, where an inteffacial domain wall is allowed to extend into either the ferromagnetic or antiferromagnetic layer or across both. The proposition is based on our theoretical investigation on thickness and field dependences of ferromagnetic domain wall （FMDW） and antiferromagnetic domain wall （AFDW）, respectively. Good match of the simulation to the hysteresis loops of a series of NiFe/FeMn exchange-biased bilayers confirms the existence of the HIDW, where the AFDW part is found to preferentially occupy the entire antiferromagnetic layer while the FMDW shrinks with the increased magnetic field as expected. The observed asymmetry between the ascending and descending branches of the hysteresis loop is explained naturally as a consequence of different partition ratios between AFDW and FMDW.
