Abstract: An aerosol generating article includes: a first segment impregnated with a first liquid composition; a second segment impregnated with a second liquid composition that is different from the first liquid composition; a cooler configured to cool aerosol by allowing the aerosol, generated from the first segment or the second segment, to pass through the cooler; and a filter configured to filter the aerosol by allowing the aerosol having passed through the cooler to pass through the filter, wherein at least a portion of the filter is recessed to thereby form a cavity in the filter.

Abstract: A display device includes a substrate including an active area having pixels and a non-active area including a pad region. A pad electrode is disposed in the pad region and includes a first pad electrode and a second pad electrode disposed on the first pad electrode. A first insulating pattern is interposed between the first and second pad electrodes. In a plan view, the first insulating pattern is positioned inside the first pad electrode, and a portion of the second pad electrode overlapping the first insulating pattern protrudes further from the substrate in a thickness direction than a portion of the second pad electrode not overlapping the first insulating pattern. The second pad electrode directly contacts a portion of the upper surface of the first pad electrode. In a plan view, an area of the second pad electrode is greater than an area of the first pad electrode.

Abstract: A method of identifying an alveolar nerve region in a mandible image for dental implantation. The method includes: (a) slicing the 3-dimensional mandible image into a number of 2-dimensional slice images; (b) detecting a binary image object corresponding to a mandible region from one of the slice images; (c) grouping pixels of the binary image object of the mandible region into clusters each containing pixels having a similar intensity; (d) determining clusters that have pixels more than a predetermined minimum number of pixels, and determining the minimum labeled cluster having the lowest pixel intensity distribution among the clusters; (e) composing a new binary image containing pixels which belong to both the mandible region and the clusters having intensity distribution lower than that of the minimum labeled cluster, to extract a candidate nerve object; and (f) determining whether the candidate nerve object corresponds to the real alveolar nerve region.
