Abstract: A CMOS inverter circuit includes a first and second PMOS transistor connected in series to a power supply voltage (VDD) and a first NMOS transistor connected in series with the second PMOS transistor and to ground (GND). All transistors receive the same input signal.
This configuration enables normal logic gate operation even when the P-channel characteristics of the PMOS transistors are shifted. The channel widths of the first and second PMOS transistors can be varied to adjust circuit performance.-

Abstract: A search method using an artificial intelligence based information retrieval model and a method for training the artificial intelligence based information retrieval model used for the method are provided.
In the method, even if there is no labeled data and only a corpus exists, the artificial intelligence based information retrieval model can be trained using the weak-supervision methodology. Search can be performed by dividing documents into passages having short lengths. Compared to an information retrieval model based on unsupervised learning, improved search results are provided.-

Abstract: Disclosed are a pharmaceutical composition and a beauty-purposed pharmaceutical composition for prevention or treatment of neuromuscular disease, the composition including a combination of Erigeron annuus flower-based essential oil and Botox. Erigeron annuus flower-based essential oil inhibits t-SNARE protein and v-SNARE protein expression in neurons to inhibit the formation of SNARE protein complexes. Erigeron annuus flower-based essential oil inhibits the regeneration of t-SNARE protein and v-SNARE protein degraded by Botox to inhibit neurotransmitter release. Accordingly, an efficacy duration of Botox may be extended. Thus, Erigeron annuus flower-based essential oil may be usefully used in combination with Botox as Botox adjuvant for the prevention and treatment of neuromuscular disease or for beauty.

Abstract: Canceling and removing distortion and noise components of a signal generated in a hybrid fiber-coax (HFC) network. The system transmits an optical signal from an input side of an optical network unit of an existing HFC network to a coaxial distribution hub through a separate optical fiber jumper; converts the optical signal into a reference RF signal; extracts only the distortion and noise component by combining the reference RF signal with the degraded main RF signal, in opposite phase, containing distortions and noises generated, while the main RF signal passes through coaxial cables and cascaded coaxial amplifiers in coaxial paths of an HFC network; canceling out the distortion and noise component by combining the extracted distortion and noise component with the degraded main RF signal, in opposite phase.

Abstract: The present invention provides an inverter and a bootstrap inverter with improved output characteristics. The inverter comprises a first and second load transistors, a driving transistor, and a control transistor. The control transistor, when turned on, effectively grounds the source of the first load transistor, ensuring a 0V output. The bootstrap inverter further includes a bootstrap transistor and a capacitor. This configuration solves the problems of output voltage being lower than VDD for logic ‘1’ and not completely 0V for logic ‘0’, achieving ideal output levels.

Abstract: The present invention relates to a method and a system for recognition of objects near a ship by using a deep neural network to prevent a collision with the object by recognizing a neighboring object that may be risky to the ship sailing in a restricted condition such as a foggy environment. All object movements within a predetermined radius are detected and recognized so that collision accidents with objects on the sea in an environment such as fog caused by bad weather at sea can be prevented, and a risk alarm is notified to a captain when the object is detected so that collision accidents can be remarkably reduced. In addition, peripheral environments are detected by only installing a CCTV camera so that expenses can be reduced, human negligence can be prevented, and the system can be easily constructed to prevent collisions.
