Heart failure （HF） is a potentially fatal disease that affects increasing number of people worldwide. Although heart transplant is the ＂gold standard＂ therapy for HF, due to the limited availability of organs, many patients died when waiting for the transplant. Left ventricular assist device （LVAD）, as a mechanical circulatory support, has become a new light for patients with HF. With the technical advancements, LVADs work not only as a bridge to transplant, but also assist heart recovery and even as a destination therapy in long-term treatment. This observation paper reviewed the development of LVAD and its clinical roles. The challenges and possible solutions in nursing care for pa- tients with LVAD at different stage of implantation were discussed. The healthcare professionals could obtain a better understanding about the LVAD treatment for HF patients.

1948年由位于北京城的“中电三厂”出品的电影《深闺疑云》,直接回应了在抗战期间上海曾经上映过的希区柯克导演的作品《深闺疑云》(suspicion),在剧本人物权力关系的置换中完成了因应战乱时代的集体焦虑表达,同1950至60年代由中国香港生产、改编自希区柯克作品《后窗》《迷魂记》的粤语电影《后窗》《回魂夜》一起,组成了一条清晰的华语电影“借桥”希区柯克的脉络。徐昌霖版《深闺疑云》、中国香港版《后窗》和《回魂夜》等三部电影虽然都不曾明确宣布对西片原作的借重,但不约而同步地走上了一条与传统意义上的中国侦探电影或“含有侦探内容”的电影截然不同的“心探”路径。这三部侦探电影作品不仅承继了相关类型的商业特征,更在顺势应时的具体改编中回应了20世纪中期中国内地与中国香港变动不居的社会政治经济格局,形成了“仿作者以言志”或“解构作者以言志”的独特电影创作兴味。同时,这些影片中叙事策略的“伦理化”倾向,直接导致了对希区柯克电影之于好莱坞工业“解构性”的再度解构,形成了既符合不同时代的华语电影主流受众的认同,同时亦体现创作者自身的“电影本体”探索的电影文本转译特点。

shape-memory effect(sME) is the ability of a material to change its dimension in a predefined way in response to an external stimulus. Polymers that exhibit sME are an important class of materials in medicine, especially for minimally invasive deployment of devices. However, the rate of translation of the concept to approved products is extremely low, with mostly nitinolbased devices being approved. In this review, the general aspects of the different types of stimuli that can be used to activate sME are reviewed and sterilization issues of shape-memory polymer(sMP)-based medical devices are addressed. In addition, the general usefulness as well as the limitations of the shape-memory effect for biomedical applications are described.

椭圆曲线密码系统是最近十几年来获得迅速发展的一类密码系统.为了提高椭圆曲线密码系统的处理速度,针对其中最关键的运算——椭圆曲线标量乘法设计并实现了一种基于FPGA的硬件结构,完成GF(2m)上的椭圆曲线标量乘法计算.该结构最大程度地对标量乘算法的内部模块进行了并行处理,缩短最大延迟路径,从而达到提高运算速度的目的.这一结构在FPGA上实现后,计算一次GF(2163)上的椭圆曲线标量乘法只需要36μs,这一性能是目前国际上已知的基于FPGA的标量乘法器中最好的.

Time-series discord is widely used in data mining applications to characterize anomalous subsequences in time series. Compared to some other discord search algorithms, the direct search algorithm based on the recurrence plot shows the advantage of being fast and parameter free. The direct search algorithm, however, relies on quasi-periodicity in input time series, an assumption that limits the algorithm＇s applicability. In this paper, we eliminate the periodicity assumption from the direct search algorithm by proposing a reference function for subsequences and a new sampling strategy based on the reference function. These measures result in a new algorithm with improved efficiency and robustness, as evidenced by our empirical evaluation.

Concentrations of C-reactive protein (CRP) in the serum of 14 patients suffering from Lyme diseasc were measured. 86% of these patients were found to have abnormally high concentrations of serum CRP (range 14-158 mg/L). The CRP concentration of a 60-yearold patient abated from 29 mg/L to 13 mg/L after treatrnent. Results suggest that serum CRP concentration can provide a valuable and accurate means for the clinical diagnosis and monitoring of Lyme disease

Background: Lack of an observable vertical impact peak in fore/mid-foot running has been suggested as a means of reducing lower extremity impact forces, although it is unclear if impact characteristics exist in other axes. The purpose of the investigation was to compare three-dimensional(3 D) impact kinetics among foot-strike conditions in over-ground running using instantaneous loading rate–time ***: Impact characteristics were assessed by identifying peak loading rates in each direction(medial–lateral(ML), anterior–posterior(AP),vertical, and 3 D resultant) following foot-strike instructions(fore-foot, mid-foot, subtle heel, and obvious heel strike). Kinematic and kinetic data were analyzed among 9 male participants in each foot-strike ***: Loading rate peaks were observed in each direction and foot-strike condition, differing in magnitude by direction(3 D resultant and vertical > AP > ML, p ≤ 0.031) and foot-strike: ML(fore-foot and mid-foot strike > obvious heel strike, p ≤ 0.032), AP(fore-foot and mid-foot strikes > subtle-heel and obvious heel strikes, p ≤ 0.023). In each direction, the first loading rate peak occurred later during heel strike running relative to fore-foot(p ≤ 0.019), with vertical and 3 D resultant impact durations exceeding shear(ML and AP, p ≤ 0.007) in each ***: Loading rate–time assessment identified contrasting impact characteristics in each direction and the 3 D resultant following foot-strike manipulations, with potential implications for lower extremity structures in running.
