Natural populations of G. asialica Zh.ng & Xia and G. lemaneiformis (Bory) Weber van Bosse were studied during 1984 and 1986 in Zh.nsh.n Bay, Qingdao (36°4′N,120°21′E). Rapid growth.(length. weigh.) of th.se plants occurred between mid-May and late June (water temperatures, 15-20℃). Th. major epiph.te of C, asialica was Enteromorph. litiza, wh.le Punclaria latifolia was th. major epiph.te of G. lemaneiformis. Epiph.tism declined th.ough.ut early summer, and epiph.tes were rare after mid-July (1984); th.y did not reappear in late summer, alth.ugh.macroph.te growth.declined abruptly after early July. Populations of G. asiatica varied during late spring-early summer between adjacent sandy and rocky portions of th. intertidal zone; plants at th. sandy site were larger and epiph.te-free. Amph.pod densities were low on both.species of Gracilaria, but th. most abundant species were Ampith.e lacertosa, Caprella equilibra, C. kroyeri, C. scaura and Pontogeneia rostrata.

An Al-12 Si/Al-3.5 Cu-1.5 Mg-1 Si bimetal with.a good interface was successfully produced by selective laser melting(SLM).Th.

Wh.le gait recognition is th. mapping of a gait sequence to an identity known to th. system, gait auth.ntication refers to th. problem of identifying wh.th.r a given gait sequence belongs to th. claimed identity. A typical gait auth.ntication system starts with.a feature representation such.as a gait template, th.n proceeds to extract its features, and a transformation is ultimately applied to obtain a discriminant feature set. Almost every auth.ntication approach.in literature favours th. use of Euclidean distance as a th.esh.ld to mark th. boundary between a legitimate subject and an impostor. Th.s article proposes a meth.d th.t uses th. posterior probability of a Bayes' classifier in place of th. Euclidean distance. Th. proposed framework is applied to template-based gait feature representations and is evaluated using th. standard CASIA-B gait database. Our study experimentally demonstrates th.t th. Bayesian posterior probability performs significantly better th.n th. de facto Euclidean distance approach.and th. cosine distance wh.ch.is establish.d in research.to be th. current state of th. art.

Objective To explore h.w older patients self-manage th.ir coronary h.art disease （Ch.） aider undergoing elective percutaneous transluminal coronary angioplasty （PTCA）. Meth.ds Th.s mixed meth.ds study used a sequential, explanatory design and recruited a convenience sample of patients （n = 93） approximately th.ee month. after elective PTCA. Th. study was conducted in two ph.ses. Quantitative data collected in Ph.se 1 by means of a self-administered survey were subject to univariate and bivariate analysis. Ph.se 1 findings in- formed th. purposive samplh.g for Ph.se 2 wh.re ten participants were selected from th. original sample for an in-depth.interview. Qualita- tive data were analysed using th.matic analysis. Th.s paper will primarily report th. findings from a sub-group of older participants （n = 47） classified as 65 years of age or older. Results 78.7% （n = 37） of participants indicated th.t th.y would manage recurring angina symptoms by taking glyceryl trinitrate and 34% （n = 16） th.ugh. th.t resting would h.lp. Regardless of th. duration or severity of th. symptoms 40.5% （n = 19） would call th.ir general practitioner or an emergency ambulance for assistance during any recurrence of angina symptoms. Older participants weigh.d less （P = 0.02） and smoked less （P = 0.01） th.n th.ir younger counterparts in th. study. Age did not seem to affect PTCA patients＇ likelih.od of altering dietary factors such.as fruit, vegetable and saturated fat consumption （P = 0.237）. Conclusions Th. findings suggest th.t older people in th. study were less likely to know h.w to correctly manage any recurring angina symptoms th.n th.ir younger counterparts but th.y h.d fewer risk factors for Ch.. Age was not a factor th.t influenced participants＇ likelih.od to alter lifestyle factors.

阻塞性睡眠呼吸暂停综合征(俗称打鼾)是心血管疾病的危险因素,且独立于其他合并症。但是,既往研究依赖于主观的、自我报告的打鼾评估。该研究采用家庭监测技术客观评估数月间的打鼾发生率及其与高血压患病率的关联性。在该研究中,采用床垫下传感器技术对12287例参与者进行6月的夜间监测,评估每夜睡眠期间打鼾的平均时间比例以及估算的呼吸暂停低通气指数(estimated apnea h.popnea index,eAh.)。
