Abstract: Provided is a method of eliminating the dependence of methanol induced promoter on a single methanol carbon source for expressing foreign polypeptide. The method comprises activating the expression of the promoter requiring methanol induction by increasing the expression quantity of Mit1 polypeptide in cells of methylotrophic yeast, so that the promoter originally depending on methanol induction no longer depends on single methanol and can also express foreign polypeptide.

Abstract: Snippets can be represented in a language-independent semantic manner. Each portion of a snippet can be represented by a combination of a semantic representation and a syntactic representation, each in its own dimensional space. A snippet can be divided into portions by constructing a dependency structure based on relationships between words and phrases. Leaf nodes of the dependency structure can be assigned: A) a semantic representation according to pre-defined word mappings and B) a syntactic representation according to the grammatical use of the word. A trained semantic model can assign to each non-leaf node of the dependency structure a semantic representation based on a combination of the semantic and syntactic representations of the corresponding lower-level nodes. A trained syntactic model can assign to each non-leaf node a syntactic representation based on a combination of the syntactic representations of the corresponding lower-level nodes and the semantic representation of that node.

Abstract: A SIM card connector includes a base, signal spring, a detection apparatus, and a controller. The detection apparatus includes a fixed contact and a detection spring. An action of a SIM card can be detected by means of separation or union between the fixed contact and the detection spring. A trigger part of the detection spring can press against a surface of the SIM card to move a movable end of the detection spring. A power supply of the signal spring can be cut off before the SIM card is separated from the signal spring, and the power supply of the signal spring can be switched on after the SIM card presses against the signal spring.

Abstract: A SIM card connector includes a base, signal spring, a detection apparatus, and a controller. The detection apparatus is configured to cooperate with one side of a SIM card, and includes a fixed contact and a detection spring, where an action of the SIM card can be detected by separation or union between the fixed contact and the detection spring. The controller can disconnect a power supply of the signal spring before the SIM card is separated from the signal spring, and can switch on the power supply of the signal spring after the SIM card presses against the signal spring, which effectively prevents the SIM card from being burned out by a momentary electric arc generated between the SIM card and the signal spring when the SIM card is being inserted or removed.

Abstract: Three dimensional printed objects having surface coatings, such as a hydrophobic coating or metalized surface, 3D printed substrates having an outer surface that can be tuned by application of such a coating, and methods for the fabrication of such objects and substrates are described. A surface initiator is incorporated into the 3D substrate during layer-by-layer printing, and the surface coated by surface-initiated atom transfer radical polymerization (SI-ATRP).

Abstract: An active device for dynamic control of lightwave transmission properties has at least one photonic crystal waveguide that has anti-reflection photonic crystal waveguides with gradually changed group refractive indices at both input and output side. An alternating voltage or current signal applied to two electrically conductive regions changes the refractive indices of the photonic crystal materials, introducing a certain degree of blue-shift or red-shift of the transmission spectrum of the photonic crystal waveguide. The output lightwave with frequency close to the band-edge of the photonic crystal waveguide is controlled by the input electric signal. Devices having one or more such active photonic crystal waveguides may be utilized as an electro-optic modulator, an optical switch, or a tunable optical filter.

Abstract: An anti-creep mechanism for coupler includes a lower lockpin rod, a coupler shank and a rotation shaft. The rotation shaft is disposed in an elongate mounting hole of the lower lockpin rod and a circular mounting hole of the coupler shank so that the lower lockpin rod and the coupler shank are hinged together. A boss is axially disposed on an upper surface of the rotation shaft, and a groove is axially provided in a wall of the mounting hole of the coupler shank above the rotation shaft to receive the boss of the rotation shaft. The rotation shaft is axially movable relative to the lower lockpin rod and the coupler shank and has two operating positions. When the rotation shaft is moved to the first operating position, an inner end portion of the boss is positioned in the elongate mounting hole of the lower lockpin rod, and a top wall of this elongate mounting hole abuts against the boss.

Abstract: A method for amplifying oligonucleotide in vitro by polymerase-endonuclease chain reaction (PECR) which utilizes a single-stranded DNA probe containing repeat sequences, extends a target oligonucleotide by a thermostable DNA polymerase, cleaves extended products with a thermostable endonuclease, and amplifies target oligonucleotide by thermocycling. In PECR, a specific oligonucleotide is exponentially amplified using one single probe instead of a pair of primers, and the reaction is precisely controlled by thermal cycles whose parameters are flexibly adjustable according to length, sequence, melting temperature and initial amount of the target oligonucleotide. Amplification speed depends totally on initial amount of target oligonucleotide present in the reaction system. The method can be used to amplify specific small nucleic acids, such as oligonucleotides and microRNAs, and further conduct quantitative analysis.
