Aims: Anaemia is a common comorbidity in chronic heart failure(CHF). The predictors of new onset anaemia(NOA) and its long-term prognostic value, particularly in patients treated with beta-blockers, are not known. Methods and results: In COMET, 3029 patients with CHF in NYHA Ⅱ-IV and EFs. Plasma haemoglobin(Hb) concentrations were measured at a central laboratory at randomization, at four monthly intervals for the first year and annually thereafter. According to WHO criteria, anaemia was defined when Hb measuredsidered anaemia to be severe when Hbseline mean Hb was 14.2±1.5 g/dL(n=2996) and 15.9%of patients had anaemia(males, 16.0%; females, 15.2%). At baseline, severe anaemia was found in 3.3%of patients(males, 3.6%; females, 2.0%). During the study, all-cause mortality(RR 1.47) death or hospitalization(RR 1.28), and heart failure hospitalization(RR 1.43, all Ps. In patients without anaemia at baseline, at the end of the study, the cumulative frequency of NOA was 28.1%in males and 27.0%in females. NOA increased over time from 14.2%at year 1 to 27.5%at year 5. Predictors of NOA were: higher age, diuretic dose, creatinine(all Pserum potassium, lower serum sodium, body mass index, and use of aldosterone antagonists, carvedilol, and digitalis(all Ps. metoprolol tartrate) was associated with a 24%increased risk to develop NOA(P=0.0047),but not severe anaemia(P=0.18). Patients with a Hb decrease of >3 g/dL(RR 3.37, Pseline had an increased subsequent mortality when compared with patients having Hb increases of 0-1.0 g/dL.

在本文中,我将把建筑师菲利普·比斯利(PhillipBeesley)的动态雕塑作品《生命空间(Hylozoic Ground)》与关乎人类主体的一组理论和哲学研究相联系。在这种语境下,怀着"生命"和"意识"间之密切关系的预期,我将探讨"什么是生命"这一深刻的哲学问题。在亚伊尔·纽曼(Yair Neuman,2008年)和索伦·布莱尔(srenBrler,2008年)的启发下,我将使用下述概念:"生命"和"意识"直接关系到身体内的各种交流过程,无论是有形可测量还是无法测量的。而且对这种交流过程最好的描述,是根据其性质的不同建立分级模型——除了相互依存的各种交流。

Toward the implementation of a universal angle-based optical indoor positioning system

引用

Frontiers of Optoelectronics 2018年第2期11卷 116-127页

作者： Mark H. BERGEN Ferdinand s. sCHAAL Richard KLUKAs Julian CHENG Jonathan E HOLZMAN Faculty of Applied science University of British Columbia Kelowna BC V1V 1V7 Canada Technical University of Denmark Anker Engelunds Vej 1 Bygning 101A 2800 Kgs. Lyngby Denmark

There is an emerging market today for indoor positioning systems capable of working alongside global navigation satellite systems, such as the global positioning system, in indoor environments. Many systems have been proposed in the literature but all of them have fundamental flaws that hold them back from widescale implementation. We review angle-of-arrival （AOA） and angle-difference- of-arrival （ADOA） optical indoor positioning systems which have been proven to be robust, accurate, and easily implementable. We build an AOA/ADOA optical indoor positioning system out of a simple commercial high-speed camera and white light light emitting diodes （LEDs） which operate over a working area of 1 m3, and compare its performance to other indoor positioning methods. The AOA and ADOA systems achieve positioning with low errors of 1.2 and 3.7 cm, respectively.
