Abstract: The disclosure relates to a tobacco material including a flavor material and a method of preparing the tobacco material. The tobacco material may have a core-shell structure in which a core includes a first tobacco mixture and a flavor material and is surrounded by a shell including a second tobacco mixture, such that the aerosol generating article including the tobacco material generates a characteristic flavor.

Abstract: An embodiment of the present disclosure discloses tobacco material including: a center portion including a flavor material; and an outer portion including a tobacco mixture, wherein the outer portion surrounds the center portion.

Abstract: Provided are a resource allocation method and device in a multi-node system comprising a plurality of nodes and a base station which is connected to each of the plurality of nodes and controls same. The method comprises: partitioning wireless resources which the base station can use; and allocating the partitioned wireless resources to the plurality of nodes, respectively, wherein the wireless resources allocated to the plurality of nodes, respectively, have different frequency bands or frame structures between the nodes which may cause interference.

Abstract: A method for allocating fractional frequency reuse (FER) resources to perform cooperative MIMO in a multi-cell environment is disclosed. A cell which requests FER resources decides a band for cooperative MIMO with its neighboring cell, and requests the neighboring cell to allocate the decided band for cooperative MIMO. A cell which receives FER resource request receives a request from a neighboring cell to allocate some or all of FER bands allocated to the neighboring cell as a band for cooperative MIMO, decides whether to grant the request, and allocates some or all of the requested FER bands as the band for cooperative MIMO with the neighboring cell if the request is granted.

Abstract: Disclosed herein are pyridine derivatives, or a pharmaceutically acceptable salt, ester, amide, or prodrug thereof, pharmaceutical compositions comprising the same, and methods of modulating the level or activity of HIF in a subject, inhibiting hydroxylation of HIF ? in a subject, modulating expression of HIF-regulated genes in a subject, treating an HIF-related disorder in a subject, increasing levels of endogenous EPO in a subject, or treating a disorder in a subject, using the disclosed compounds.
