The present invention relates to an optoelectronic module using spatial light modulators and an optical computer comprising same. The optoelectronic module using the spatial light modulators comprises: a plurality of first light sources; a plurality of first lenses that reduce the divergence angles of light rays emitted from the first light sources; a plurality of spatial light modulators that adjust the intensity of light rays that pass through the first lenses; a plurality of light detectors that acquire a current value dependent on light intensity; and a lens unit that focuses the light rays, emitted from the first different light sources, onto one of the light detectors. The lens unit carries out the function of calculating the convolution of a light source array and a pixel array of the spatial light modulators by using the function of focusing the light rays, emitted from the first different light sources, onto the one light detector.

Abstract

The present invention relates to a ferritin nanocage fused with a LAG3 binding peptide and use thereof as an anticancer immunotherapeutic agent, in which, by respectively fusing peptides that bind to immune checkpoint receptor LAG3 (LAG3pep1: CIRNDPAVC and LAG3pep2: CSVLNASGC) to loops protruding from the surface of human ferritin to form a cage, a nanocage in which 24 LAG3 binding peptides are displayed was produced. The nanocage of the present invention increased immune activity by specifically binding to LAG3 receptors and blocking LAG3, and exhibited an anticancer effect by effectively targeting brain cancer tissues through BBB. In addition, an immune checkpoint blocking nanocage in which an LAG3 binding peptide and a PD-L1 binding peptide are fused together specifically binds to each receptor, thereby exhibiting a bifunctional immune checkpoint blocking effect. Therefore, the nanocage technology of the present invention is expected as a next-generation drug that overcomes the limitations of immune checkpoint blocking therapy using antibodies.

Abstract

The present invention relates to a method for manufacturing a Mg/Ti composite, and a metal composite manufactured thereby, the method immersing, in a molten metal that contains (Mg) and calcium (Ca), a precursor alloy (Ti-X) that contains titanium (Ti) and a metal (X), which is miscible with the molten metal so as to be dissolved into the molten metal, wherein the Ca alloy element, which is included in a molten Mg-Ca alloy, is highly miscible with Cu so as to promote dealloying behavior by which Cu is dissolved into the molten metal, thereby greatly reducing process time, is dissolved in Mg matrix so as to increase the volume fraction of the Mg matrix in the composite, and reduces the coarsening rate of Ti and, simultaneously, improves the strength of the composite through solid-solution strengthening of the Mg matrix.

Abstract

The present invention relates to a method for manufacturing a Mg/TiAl composite, and a Mg/TiAl composite manufactured thereby, the method comprising the steps of: (a) immersing, in a molten metal containing magnesium (Mg), a precursor alloy (Ti-X) containing a metal (X), which is miscible with titanium (Ti) and is to be dissolved in the molten metal, thereby manufacturing a Mg/Ti composite; (b) manufacturing a titanium (Ti) porous structure from the Mg/Ti composite; and (c) immersing the titanium (Ti) porous structure in a molten Mg-Al alloy, thereby manufacturing a Mg/TiAl composite. A magnesium matrix material is removed from a Mg-Ti composite manufactured through liquid metal dealloying (LMD), and then aluminum alloying is performed using the molten Mg-Al alloy, and thus a Mg/TiAl composite structured to be a three-dimensionally interconnected, in which an element such as copper (Cu) contained in the precursor alloy does not remain and which has excellent physical properties, can be manufactured.

Abstract

The present disclosure relates to ultra-high speed digital signal integrity improving structures. Each structure in the present disclosure includes a first unit structure and a second unit structure of the same or different shapes arranged to face each other on the left and right sides along a longitudinal direction of a balanced line, centered around a coplanar stripline (CPS) or parallel stripline (PSL) formed on a substrate. At least one of the first unit structure and the second unit structure includes a first side close to the balanced line and having a linear or curve shape; a second side facing the first side; and left and right sides connecting the first side and the second side. Here, the width of the first side is less than or equal to that of the second side, the left and right sides have a linear or non-linear slope, and the width from the first side to the second side is configured to change continuously or discontinuously. When the structures of the present disclosure are disposed around a balanced line, it has the advantage of being able to recover the distorted phase autonomously while rejecting a common-mode signal in a frequency band up to 40 GHz or more.
