摘要：
We demonstrate a high-operating-temperature(HOT)mid-wavelength InAs/GaSb superlattice heterojunction in-frared photodetector grown by metal-organic chemical vapor deposition.High crystalline quality and the near-zero lattice mis-match of a InAs/GaSb superlattice on an InAs substrate were evidenced by high-resolution X-ray diffraction.At a bias voltage of-0.1 V and an operating temperature of 200 K,the device exhibited a 50%cutoff wavelength of~4.9μm,a dark current dens-ity of 0.012 A/cm^(2),and a peak specific detectivity of 2.3×10^(9) cm·Hz^(1/2)/W.

Humid air awaited my arrival at Fuzhou Changle Airport.Upon emerging from the airport,I found myself overwhelmed by mountains embracing Fuzhou.I also couldn’t help but notice roots hanging to the ground from the branches of banyan trees on either side of the streets.

上個星期六,我的一個美國同學(xué)搬新家,順道邀請我去做客他給我的信中是這樣寫的:Ihave a jacuzzi(hot tub)so bring a swim suit if you want to do that.I have a pool table too.大家知不知道"pool table"是什么意思。當時我以為是指泳池邊的桌子,結(jié)果到底是什么呢?小笨霖先賣個關(guān)子,看完本期的內(nèi)容你就知道了。
摘要：
本發(fā)明涉及真核基因表達的轉(zhuǎn)錄調(diào)控因子的應(yīng)用，特別是涉及一種組成型啟動子Pgap的轉(zhuǎn)錄調(diào)控因子Hot1p的應(yīng)用。本發(fā)明公開了Hot1p作為正調(diào)控因子在提高宿主細胞中蛋白表達中的應(yīng)用，所述Hot1p的氨基酸序列是由核苷酸序列為SEQ ID NO:1的Hot1基因所編碼的；所述應(yīng)用為通過在啟動子Pgap后插入Hot1基因從而提高宿主細胞中蛋白的表達。本發(fā)明所述的應(yīng)用能增強畢赤酵母組成型啟動子Pgap啟動子的轉(zhuǎn)錄，從而使其后的外源基因在畢赤酵母中高效表達，而且可以避免多拷貝或者多基因表達時，使用同一啟動子產(chǎn)生的稀釋效應(yīng)，導(dǎo)致不同基因表達量差異過大。
