I know what the recurrence of disease is.
it means the disease occurs again.

previous recurrent abdominal pain and past diagnosed diseases including

数学家们,
f(n) <= 4*f(n/2) + 2n
What would be the solution to this recurrence inequality?
I seemed to remember this is related to the divide-and-conquer algorithm and
to O(n*logn)... Right now my mind is so full and tired that I cannot think or
reason coherently, so please help me. If this f(n) <= 4*n^2, then my research
finally has some hope!!!
Thanks a million!!!!!!

标 题: 抑郁症有妄想表现吗?
发信站: BBS 未名空间站 (Wed Jan 21 14:54:12 2015, 美东)
张纯如精神障碍的正式诊断是抑郁症。根据美国精神病诊断权威标准DSM-5(附件1),
抑郁症是没有妄想表现的。也就是说,如果一个人被诊断为抑郁症,就不应该有妄想表
现。如果一个人有妄想表现,就不应该诊断为抑郁症。
那么确诊为抑郁症的病人是否可以出现妄想呢?回答是肯定的。但是,当一个抑郁症病
人出现妄想症状,原来的“抑郁症”就不再适用于病人。这种情况下就要改变诊断为“
精神病性抑郁症”。这种病人往往同时会出现幻觉症状。相应的治疗和保护措施也要作
出改变。相关学术依据见附件2。
有些人说张纯如有精神病。所谓的日本右翼极端势力对她不断发出暴力威胁其实是她的
妄想。起码从医生给她的正式诊断来看,张纯如没有妄想症状。

我来说一下第二个题,作为一个面试题的话,那简直难到爆炸。是我们graduate概率课
的一个例子,做为一道一小时完成的ECE qualify题目完全是有可能的。这个题叫做
First Occurrence of Successive Hits。
Let y_m 表示题目要求的,flip出m个head需要的平均次数(期望)。
To analytically get y_m,需要下面这个recurrence equation:
y_m = y_{m-1}/p + 1/p
初始条件,y_1 = 1/p (其实算出这个初始条件都不简单了,你需要知道 geometric
random variable 的特殊性质,不信你试试看。。。)
这题答案看上去很简单,但是要得到那个recurrence equation是很花时间的,要用到
expectation的很多高级性质,我估计LZ在简历说了自己概率或者数学很厉害什么的,
我很难想象面试能有这种题!!!面试官黑的漂亮!!!

你这个要告的话,基本上没有希望能赢。
主要是PREXISTING的FILLING的大小和RECURRENT DECAY的大小,直接影响到
可能的结果。
如果以前的FILLING本身就比较大,而RECURRENT DECAY的SIZE也不小,那么
当DDS清理的时候,很有可能会很接近或者触到神经。
那么从FILLING变成ROOT CANNAL加CROWN的机率很大的。
通常如果DDS觉得有机会不需要做RCT的话,就会先做FILLING。而重新做的大的FILLING
后,有不少人都需要相当一段时间才能渐渐消除SENSITIVITY。我知道有人半年才好的
。当然如果一直很SENSITIVE,那么就要做RCT+CROWN了。
这是非常常见的情况。
另外,你要看的是ENDODONTIST不是ORTHODONTIST做RCT(根管治疗)。

metastasis in a few years. but large scale clinical studies showed that
chemotherapy does not decrease the chance of recurrence or metastasis and
does not increase the chance of long-term survival.

It could be that you gave oral herpes (hsv1) to her through oral sex; or
genital herpes (hsv2) through genital contacts before you wear condom for
penetration. For hsv1, you might not notice you have had active sores, which
is quite common (by estimate, up to 80% of the population carries hsv1).
For hsv2, you may have had it before, but it's less painful on recurrence
that's why you might not notice it. From what I have known, only when you
have active sores, it is contagious. Although many peop... 阅读全帖

谢谢您的回复!
您是说双原发的说法没有依据么?病理分析没法得出确切结论?一般的科普资料上貌似
找不到这个说法,倒是一些专业的医学期刊文章上有提到double primary cancer/
tumor, 不是很懂这个名称严格的定义和鉴定的方法。请问您对我妈妈的这种情况的分
期有什么看法或者建议么?非常感谢!
查了一些科普资料,确实肺腺癌的复发率较高,但是貌似唯一的例外是stage I-A,这也
是为什么我比较纠结分期的地方。貌似Stage I-A的手术后的预后相对还不错,美国的
