The HA-FXC50 provides excellent sound and superior sound isolation by
employing an innovative MICRO-HD driver unit, loaded into the tip of the
earphone housing. Different from conventional in-ear earphones, this allows
the driver unit to stay in the ear canal, delivering high-definition sound
directly into the ear without diffused reflection. The silicon earpieces are
both comfortable and practical, fitting securely |

发帖数: 305 | 6 My explaination is that the sum follows a diffusion equation, and drifts
away from origin. This means that
the left most number (16) gets the most flux. But after the peak of the
distribution passes 15, the numbers
16, 17 ... will get more probability. So I'm not sure how to show that the
game is more likely to have stopped
before the peak passed 15, though it may look obvious.
What if we stop when the sum is above 12? My feeling is that the answer may
not be 13.
Can you check?

I didn't google for this. I studied water treatment in
university.
The spent exchange medium can be regenerated with a solution
with very high and pure sodium concentration. Let's use
calcium as example. If the calcium in water is extremely low
and the sodium is extrememly high (say, 10%), calcium will
diffuse to water and sodium will replace calcium untill it
reaches chemical equilibrium. If you do it with running
solution, all calcium will be replaced ultimately (not
practical in real life). |

发帖数: 2464 | 40 一个多月前重感冒，很重很重那种，先是嗓子痛，后来都说不出话来了，咳嗽不止。
不过不发烧。
持续一周多。
期间发现颔下淋巴结肿得很厉害，很硬但不痛。
再后来吃了些消炎药感冒好了，淋巴稍小了一些，
可是最近一个月就不往下消了，还是很大。两边都有。
前几天去看医生，做了ultrasound,
说是两侧特别是颔下腺周围有几个淋巴结肿着，
让过阵子再不消再做一次。(不过最近都没消，再接着消的可能性是不是不大啊）
查血好像基本正常，血小板稍低于正常值。
后来又做了MRI，说是diffused neck adenopathy，没有tumor/mass什么的。
医生说建议再做一些blood test，加上淋巴穿刺。
要是再查不出什么就切一块淋巴下来看。
怕死了。MRI加ultrasound也还是不能排除淋巴瘤的可能么？
所以就上这里来问second opinion了。。。
