摘要： Provided is an athermal external cavity laser (ECL), whose output optical power and output wavelength can be kept regular irrespective of temperature changes without using additional temperature controlling components. The ECL comprises: a semiconductor amplifier; an optical fiber comprising a core in which a Bragg grating is formed and a cladding surrounding the core; and a thermosetting polymer that fixes the optical fiber to a ferrule and has a negative thermooptical coefficient, wherein the thickness of the cladding surrounding the core in which the Bragg grating is formed is smaller than the portion of the cladding surrounding the portion of the core where the Bragg grating is not formed, and the thermosetting polymer the negative thermooptical coefficient surrounds the cladding. The ECL does not need additional temperature controlling components and thus can be manufactured compact and at low cost, and thus can be used as a light source of a dense wavelength division multiplexing (DWDM) system in designing economical WDM passive optical networks (PON).

摘要： Disclosed are a cell-penetrating, base sequence-specific, nucleic acid-hydrolyzing antibody, a method of preparing the same, and a pharmaceutical composition comprising the same. The antibody can be prepared by modifying a particular site of a cell-penetrating, nucleic acid-hydrolyzing antibody which lacks substrate specificity to impart sequence specificity thereto without alteration in nucleic acid-hydrolyzing ability. The antibody, when penetrating into cells by itself or ectopically expressed within cells, binds specifically to single- or double-stranded nucleic acid targets and hydrolyzes them, thus downregulating the expression of the targeted genes.

摘要： A heat exchange element of a heat exchanger prevents losses due to internal pressure non-uniformity. The heat exchanger includes a plurality of heat exchange sheets which are stacked together. A plurality of airflow guide ribs located between the sheets have connection passages that allow gases to flow between adjacent ducts. The flow of gasses through the connection passages offsets pressure non-uniformity between adjacent ducts. Also, the ribs can be continuously arranged over the length of the heat exchange ducts to increase an area supporting the heat exchange sheets, and thus the sag phenomenon of the heat exchange sheet can be prevented.
