精子竞争是指同一女性产道中两个或两个以上男人的精子相互竞争卵子的过程。女性得到社会承认的性伙伴可能因精子竞争失败而损失惨重,因为女性私通可能引起男性投资于不携带自己基因的后代。过去研究表明进化而来的男性配偶监控策略可... 详细信息

精子竞争是指同一女性产道中两个或两个以上男人的精子相互竞争卵子的过程。女性得到社会承认的性伙伴可能因精子竞争失败而损失惨重,因为女性私通可能引起男性投资于不携带自己基因的后代。过去研究表明进化而来的男性配偶监控策略可以防止女性不贞,减少精子竞争失败的危险。当前研究发现男性与配偶进行性行为后离别时间越久,男性就越采取出其不意地打电话、独占配偶时间、威胁对配偶感兴趣的男性等手段来监控配偶。

Patients with acute coronary syndrome(ACS) in the Myocardial Ischaemia Reduction with Ag.ressive Cholesterol Lowering.MIRACL) study had diminished cardiovascular events after 16 weeks of treatment of atorvastatin 80 mg.daily. We determined whether plasma lipoproteins at baseline and then at 6 weeks after randomization predicted clinical outcome. Methods and results: Cox proportional hazards models were constructed to determine relations between lipoproteins and clinical endpoint events. Baseline LDL cholesterol(LDL-C)did not predict outcome. In contrast, baseline HDL-C predicted outcome with a hazard ratio of 0.986 per mg.dL increment in HDL-C, Pg.1.4% reduction in risk for each 1 mg.dL increase in HDL-C. Atorvastatin treatment profoundly lowered LDL-C, but had minimal effect on HDL-C. Neither Week 6 LDL-C nor absolute chang. of LDL-C from baseline by Week 6 had any sig.ificant impact on clinical endpoints occurring.between Week 6 and Week 16 after randomization. Conclusion Plasma HDL-C, but not LDL-C, measured in the initial stag. of ACS predicts the risk of recurrent cardiovascular events over the ensuing.16 weeks. LDL-C reduction does not account for the clinical risk reduction with atorvastatin treatment after ACS. This finding.may sug.est that the clinical benefit of atorvastatin after ACS is mediated by qualitative chang.s in the LDL particle and/or by non-lipid(pleiotropic) effects of the drug.

The paper aims at desig.ing.of two stag. cascaded ultra-wideband(UWB) low noise amplifier(LNA) by using.neg.tive imag. amplifier technique. The objective of this article is to show the performance improvement using.neg.tive imag. amplifier technique and realization of neg.tive valued lumped elements into microstrip line g.ometry. The innovative technique to realize the neg.tive lumped elements are carried out by using.Richard's Transformation and transmission line calculation. The AWR microwave office tool is used to obtain characteristics of UWB LNA desig. with hybrid microwave integ.ated circuit(HMIC) technolog.. The 2-stag. cascaded LNA desig. using.neg.tive imag. amplifier technique achieves averag. g.in of 23 dB g.in and low noise Fig.re of less than 2 dB with return loss less than-8 dB for UWB 3-10 g.z. The Proper bias circuit is extracted using.DC characteristics of transistor at biasing.point 2 V, 20 mA and discussed in detail with LNA layout. The neg.tive imag. matching.technique is applied for both input and output matching.network. This work will be useful for all low power UWB wireless receiver applications.
