Abstract: Disclosed are an integrate-and-fire neuron circuit implemented to enable an integrate-and-fire operation with only a small number of devices by using bistable resistance characteristics of the same two heterojunction NPN devices, unlike a CMOS-based integrate-and-fire neuron circuit having a complex structure, and an operation method thereof. In one or more aspects, an integrate-and-fire neuron circuit and an operation method thereof can increase neuron integration in a system by implementing an integrate-and-fire operation of neurons using only three transistors and two capacitors, or two transistors, one resistor and one capacitor, can improve the efficiency of spiking neural network learning by controlling a fire threshold point of neurons through regulation of a gate voltage of the same two NPN devices, and can expect an increase in energy efficiency of the entire system through inhibition of excessive fire by implementing excitatory and inhibitory post-synaptic potentials.

Abstract: A method of providing a texture motion effect in a multisensory media system includes generating a texture signal by using linear predictive coding (LPC) filters obtained by applying LPC to each of a column and a row forming a texture image selected from an input image and generating a texture motion by using a visual roughness of the texture signal and a depth speed of a camera.

Abstract: A tip-enhanced spectroscopy may include a substrate on which liquid containing an analyte is to be positioned, a tip extending from a fixed end to a free end adjacent to a location for the analyte, and a vibration source configured to harmonically vibrate the tip based on a preset natural frequency. The preset natural frequency may be a natural frequency of a tuning fork.

Abstract: Disclosed is an apparatus for continuous spinning of coagulative polymeric microfibers comprising an outer microcatheter, an inner microcatheter having a smaller diameter than the outer microcatheter and inserted inside the outer microcatheter, a double lumen part in which the outer microcatheter and the inner microcatheter are coaxially superimposed with a radially spaced interstitial space, and a single lumen part formed by the outer microcatheter from an end of the inner microcatheter to an end of the outer microcatheter. A core fluid supplied through an interior of the inner microcatheter comprises a coagulative polymeric fluid, and a sheath fluid supplied through the interstitial space comprises a fluid including saline, wherein the core fluid and the sheath fluid may be configured to flow coaxially in the single lumen part to generate and discharge a coagulative polymeric microfiber.

Abstract: The present invention relates to a sample holder on which a crystal sample for serial crystallography is mounted, or the like. Compared to an existing sample holder, the sample holder according to the present invention can be manufactured by a very simple manufacturing process and at low costs, and does not physically and chemically affect other equipment therearound while collecting X-ray diffraction data. Therefore, it is possible to stably operate a beam line, to increase beam time efficiency, and further to perform raster scanning so that many diffraction images can be obtained even in a small-sized chip. In addition, since the problem of evaporation of a crystallized solution does not occur even when the crystallized solution is stored in the air for a long time, the sample holder is generally easy to use compared to a previously reported sample holder. Therefore, it is expected that the sample holder is very likely to be variously applied to the fixed-target serial crystallographic research field using various samples.

Abstract: Provided is a method of fabricating a micro/nanowire having a nanometer- to micrometer-sized diameter at predetermined positions on an object. The method comprises: preparing a micro/nanopipette having a tip with an inner diameter (dpt) which is substantially the same as the diameter of the micro/nanowire to be fabricated; filling the micro/nanopipette with a solution containing a micro/nanowire-forming material; bringing the solution into contact with the object through the tip of the micro/nanopipette; and pulling the micro/nanopipette apart from the object at a pulling speed lower than or equal to a predetermined critical pulling speed (vc) to fabricate a micro/nanowire having substantially the same diameter as the inner diameter of the micro/nanopipette tip (dpt). The critical pulling speed (vc) is defined by a maximum limit of the pulling speed at which the micro/nanowire to be fabricated has the same diameter as the inner diameter of the micro/nanopipette tip (dpt).
