    • A method for calibrating a preferred disposition for a moveable first mirror of an optical switch core of a photonic crossconnect device relative to a second mirror thereof, the method comprising the steps of determining approximate geometric coordinates of the first mirror relative to the second mirror, effecting a laser light crossconnection between the first and second mirrors to produce data from which to provide first order corrections to refine the geometric coordinates, and effecting a further laser light crossconnection between the first mirror and a third mirror, to produce data from which to provide second order corrections to further refine the geometric coordinates, whereby to calibrate the first mirror such that upon initiation of a laser light crossconnection involving the first mirror, a switching element detects deviation of the first mirror from the preferred disposition thereof and effects corrective changes.

    • Polymers whose surfaces are modified by endgroups that include amphipathic surface-modifying moieties. An amphipathic endgroup of a polymer molecule is an endgroup that contains at least two moieties of significantly differing composition, such that the amphipathic endgroup spontaneously rearranges its positioning in a polymer body to position the moiety on the surface of the body, depending upon the composition of the medium with which the body is in contact, when that re-positioning causes a reduction in interfacial energy. An example of an amphipathic surface-modifying endgroup is one that has both a hydrophobic moiety and a hydrophilic moiety in a single endgroup. For instance, a hydrophilic poly(ethylene oxide) terminated with a hydrophilic hydroxyl group is not surface active in air when the surface-modifying endgroup is bonded to a more hydrophobic base polymer. If the hydroxyl group on the oligomeric poly(ethylene oxide) is replaced by a hydrophobic methoxy ether terminus, the poly(ethylene oxide) becomes surface active in air, and allows the poly(ethylene oxide) groups to crystallize in the air-facing surface. In this example, immersion in water destroys the crystallinity as the poly(ethylene oxide) sorbs water and the hydrophobic methoxy group retreats below the surface of the polymer. Also disclosed are methods and articles of manufacture that make use of these polymers.
    • 其表面被包括两亲表面改性部分的端基修饰的聚合物。 聚合物分子的两亲端基是含有至少两个具有显着不同组成的部分的端基,使得两亲性端基在聚合物体中自发地重排其定位,以将该部分定位在身体的表面上,这取决于 当该重新定位导致界面能量降低时,与身体接触的介质。 两亲性表面改性端基的实例是在单个端基具有疏水部分和亲水部分的实例。 例如,当表面改性端基键合到更疏水的基础聚合物上时,用亲水羟基封端的亲水性聚(环氧乙烷)在空气中不是表面活性的。 如果低聚聚(环氧乙烷)上的羟基被疏水性甲氧基醚末端所代替,则聚(环氧乙烷)在空气中变得表面活性,并允许聚(环氧乙烷)基团在面向空气的表面中结晶 。 在该实施例中,当聚(环氧乙烷)吸附水和疏水性甲氧基在聚合物表面下方退缩时,浸入水中会破坏结晶度。 还公开了利用这些聚合物的方法和制品。

    • A parser is provided that parses a Chinese text stream at the character level and builds a syntactic structure of Chinese character sequences. A character-based syntactic parse tree contains word boundaries, part-of-speech tags, and phrasal structure information. Syntactic knowledge constrains the system when it determines word boundaries. A deterministic procedure is used to convert word-based parse trees into character-based trees. Character-level tags are derived from word-level part-of-speech tags and word-boundary information is encoded with a positional tag. Word-level parts-of-speech become a constituent label in character-based trees. A maximum entropy parser is then built and tested.
    • 提供一个解析器,在字符级别分析中文文本流,构建汉字序列的句法结构。 基于字符的句法解析树包含词边界,词性标签和短语结构信息。 语义知识约束系统确定字边界时。 使用确定性过程将基于字的解析树转换为基于字符的树。 字符级标签是从词级词义标签中得出的,而字边界信息用位置标签编码。 词级词性成为基于字符的树的组成标签。 然后构建和测试最大熵解析器。
