But Perl hasn't left us stranded with a string when only a pair of numbers will do. By using the getpwnam function and passing the username we get an array of information about that username from the passwd file. For use in chown you'll need the 2 and 3 elements of the array. AUTHOR: Luke Melia

Micrococcal nuclease hypersensitive DNA fragments were either cloned directly, or mapped onto the genome by hybridization with oligo-nucleotide probes on a 244K Agilent array-CGH chip. The array-CGH mapping was confirmed for nuclease sensitivity by PCR after MNase digestion and by Southern blot analysis.

To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray. Of 2300 cDNA clones from low-abundance rat brain cDNA bank, 6 were identified as differentially expressed genes/ESTs in the hippocampus 35 days after lesion, in which none was confirmed by Northern blot. Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated.

Because of the presence of theory about air gun array, the designed technique of air gun array become mature, so it is widely applied in petrolic exploration and geophysics.

气枪阵列理论的提出，使得气枪阵列设计技术日趋成熟，并能够在石油勘探和地球物理探测中得到更加广泛的运用。

Chapter 2 discusses the function of optimum array based on the minimum meansquared error principle in CDMA system, the method of produce the reference signal, and proved whether the reference signal is the correspond PN code sequence or respread signal, the result of the array's weight converge can converge the same optimum weight under the condition that the PN sequence in a bit of data is long enough. In this chapter, we finally get the beam pattern and the correlate bit error rate after converge when several CDMA signal arrives in different direction.

本文的主要贡献及创新之处是：首次从理论上探讨了基于最小均方误差准则的最优天线阵在CDMA系统中的多址干扰抑制性能及其参考信号的产生方法，证明了采用有用信号相应的扩频码作为参考信号与采用将解扩信息与扩频码进行重扩频后的信号作为参考信号来调节自适应天线的权值均可使权值收敛于同一最优解。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.
