Journal of High Energy Physics, Gravitation and Cosm.logy 2023年第2期9卷 524-529页

作者： dennis m. Doren Jam.s Harasym.w Independent Researcher Wisconsin USA

A recent experim.ntal finding replicated an earlier research result, both of which dem.nstrated conflict with a specific Standard m.del prediction. The “m.on g - 2” studies have indicated that the degree of m.on precession predicted by the m.del is not the sam. as observed. The researchers offer m.ny posteriori atheoretical hypotheses as possible explanations of their findings, but no fundam.ntal theoretical understanding of the near discovery is am.ng them. This article describes both an explication for the unexpected result and describes its underlying m.chanism.based on an existing cosm.logical theory, the Probabilistic Spacetim. Theory. The paper also discusses the potential value of this theory.

Open Journal of Discrete m.them.tics 2011年第2期1卷 50-61页

作者： m.chael m. Henry dennis m. Cates 不详

This paper provides a detailed outline of a m.them.tical research exploration for use in an introductory high school or college Calculus class and is directed toward teachers of such courses. The discovery is accom.lished by introducing a novel m.thod to generate a polynom.al expression for each of the Euler sum., ΣNk=0kn,n∈Z+ . The described m.thod flows sim.ly from.initial discussions of the Riem.nn sum.definition of a definite integral and is readily accessible to all new calculus students. Students investigate the Bernoulli num.ers and the interesting connections with Pascal's Triangle. Advice is offered throughout as to how the project can be assigned to students and offers m.ltiple suggestions for additional exploration for any m.tivated student.

参考IUCN Red List Categories and Criteria,Version 3.1的等级和标准,我们于2010年3月至2012年12月对251种(含种下分类群)国产裸子植物的濒危状况进行了评估,并依据最新的研究动态,对结果做了少量修订。结果显示极危37种,濒危35种,易危76种,无危87种,数据缺乏16种;受威胁种类占评估裸子植物总数的59%。生境退化、分布面积过小和过度利用是主要的致危因子。结合实际保护案例,我们提出裸子植物濒危物种保育应有针对性措施,过度保护会进一步导致它们的濒危。

Background Undernutrition is com.on in patients adm.tted with stroke. We aim.d to establish whether the tim.ng and route of enteral tube feeding after stroke affected patients’outcom.s at 6 m.nths. m.thods The FOOD trials consist of thre e pragm.tic m.lticentre random.zed controlled trials, two of which included dysp hagic stroke patients. In one trial, patients enrolled within 7 days of adm.ssio n were random.y allocated to early enteral tube feeding or no tube feeding for m.ore than 7 days (early versus avoid). In the other, patients were allocated perc utaneous endoscopic gastrostom. (PEG) or nasogastric feeding. The prim.ry outcom.e was death or poor outcom. at 6 m.nths. Analysis was by intention to *** ings Between Nov 1, 1996, and July 31, 2003, 859 patients were enrolled by 83 ho spitals in 15 countries into the early versus avoid trial. Early tube feeding wa s associated with an absolute reduction in risk of death of 5.8%(95%CI -0.8 t o 12.5, p=0.09) and a reduction in death or poor outcom. of 1.2%(-4.2 to 6.6, p=0.7). In the PEG versus nasogastric tube trial, 321 patients were enrolled by 47 hospitals in 11 countries. PEG feeding was associated with an absolute increa se in risk of death of 1.0%(-10.0 to 11.9, p=0.9) and an increased risk of dea th or poor outcom. of 7.8%(0.0 to 15.5, p=0.05). Interpretation Early tube feed ing m.ght reduce case fatality, but at the expense of increasing the proportion surviving with poor outcom.. Our data do not support a policy of early initiatio n of PEG feeding in dysphagic stroke patients.

Background Undernutrition is com.on in hospital patients with stroke, can deve lop or worsen in hospital, and is associated with poor outcom.s. We aim.d to est ablish whether routine oral nutritional supplem.nts im.rove outcom. after stroke . m.thods The FOOD trials are a fam.ly of three pragm.tic, m.lticentre, random.s ed controlled *** m.asured the outcom.s of stroke patients who could swall ow and who were random.y allocated norm.l hospital diet or norm.l hospital diet plus oral nutritional supplem.nts until hospital discharge. The prim.ry outcom. was death or poor outcom. (m.dified Rankin scale [m.S] grade 3-5), 6 m.nths aft er enrolm.nt, m.asured unaware of treatm.nt allocation. Analysis was by intentio n to treat. Findings Between Nov 1, 1996, and July 31, 2003, 4023 patients were enrolled by 125 hospitals in 15 countries. Only 314 (8%) patients were judged t o be undernourished at baseline. Vital status and m.S at the end of the trial we re known for 4012 and 4004 patients, respectively. Supplem.nted diet was associa ted with an absolute reduction in risk of death of 0.7%(95%CI-1.4 to 2.7) and an increased risk of death or poor outcom. of 0.7%(-2.3 to 3.8). Interpretati on We could not confirm.the anticipated 4%absolute benefit for death or poor ou tcom. from.routine oral nutritional supplem.nts for m.inly well nourished stroke patients in hospital. Our results would be com.atible with a 1%or 2%absolute benefit or harm.from.oral supplem.nts. These results do not support a policy of routine oral supplem.ntation after stroke.

目的:探讨血管紧张素转化酶(ACE)基因多态性与β受体阻滞剂治疗心力衰竭患者预后的关系。方法:用聚合酶链式反应方法(PCR)检测432例收缩功能障碍性心力衰竭[左室射血分数(LVEF)<0.45]患者的ACE基因型,前瞻性随访所有患者(26.43±18.19)个月,随访终点是死亡。分析不同ACE I/D基因分型中β受体阻滞剂治疗与慢性心力衰竭患者生存率的关系。结果:ACED等位基因的生存率比Ⅰ等位基因明显降低(P=0.027);在ACEDD基因型中有β受体阻滞剂治疗组比无β受体阻滞剂治疗组的生存率明显增高(P=0.003);有β受体阻滞剂治疗组ACE II、ID、DD3种基因型的生存率无差异(P=0.196);无β受体阻滞剂治疗组ACEDD基因型的生存率比II、ID有明显降低的趋势,但无显著性差异(P=0.091)。结论:在慢性心力衰竭患者中,ACEDD基因型患者的生存率明显降低,β受体阻滞剂治疗效果与ACE I/D基因多态性有相关性,ACEDD基因型获益更大。
