Abstract: A method for mitigating a leakage signal in an FMCW radar and a radar system thereof are disclosed. The method for mitigating the leakage signal in the radar system includes generating an in-phase signal and a quadrature signal for a beat signal, generating a complex signal using the in-phase signal and the quadrature signal, concentrating a phase noise of the leakage signal included in the complex signal on a stationary point, and mitigating the phase noise based on stationary point concentration (SPC) of the phase noise.

Abstract: Disclosed is a recombinant microorganism capable of growing using only carbon dioxide and formic acid by introducing and improving a metabolic pathway for synthesizing pyruvic acid from carbon dioxide and formic acid to enhance pyruvic acid synthesis efficiency and performing additional genetic manipulation, and a method for producing useful substances using the same. Advantageously, the recombinant microorganism is capable of synthesizing pyruvic acid, a C3 organic compound, at a remarkably improved rate, and in particular, grows well even in a medium containing only carbon dioxide and formic acid as carbon sources without a glucose supply, and is thereby capable of synthesizing pyruvic acid and various high value-added compounds using the same as an intermediate product in an economically efficient manner.

Abstract: Disclosed is an SLO-aware artificial intelligence inference scheduler technology in a heterogeneous processor-based edge system. A scheduling method for a machine learning (ML) inference task, which is performed by a scheduling system, may include receiving inference task requests of multiple ML models with respect to an edge system composed of heterogeneous processors and operating heterogeneous processor resources of the edge system based on a service-level objective (SLO)-aware-based scheduling policy in response to the received inference task requests.
