Abstract: An aerosol-generating device (3) comprises an axially extending heating space (21). The heating space (21) is configured to at least partially receive an aerosol-generating article (5). The aerosol-generating device (3) comprises a heat receiving surface (25) provided outside of the heating space (21). The aerosol-generating device (3) comprises a heat storage body (31) and an inner heat conduction body (33). The heat storage body (31) is provided between the heat receiving surface (25) and the heating space (21). The inner heat conduction body (33) is provided between the heat storage body (31) and the heating space (21). A material of the heat storage body (31) has a higher specific heat capacity than a material of the inner heat conduction body (33). The material of the inner heat conduction body (33) has a higher thermal conductivity than the material of the heat storage body (31).

Abstract: To control transmissions to a user equipment (UE) over a downlink (DL) multiple-input, multiple-output (MIMO) channel, a base station determining that the UE is configured to support N DL MIMO layers and transmit reference signals over L antenna chains (852). In response to determining that L<N (870), the base station generates channel information for the DL MIMO channel using (i) L uplink reference signals, each transmitted by the UE over a respective one of the L antenna chains (880), and (ii) one or more additional transmissions received from the UE (882). The base station transmits data streams over the DL MIMO channel in accordance with the generated channel information.

Abstract: A semiconductor integrated circuit comprises a semiconductor substrate having a via-hole, a front-side-metal layer formed on a top surface of the semiconductor substrate, a seed-metal layer and a backside-metal layer. A bottom surface of an inner surface of the via-hole is at least partially defined by the front-side-metal layer. A surrounding surface of the inner surface of the via-hole is at least partially defined by the semiconductor substrate. The seed-metal layer is formed on the inner surface of the via-hole and a bottom surface of the semiconductor substrate such that the seed-metal layer and the front-side-metal layer are connected. The backside-metal layer is formed on an outer surface of the seed-metal layer. An aspect ratio of the via-hole is greater than or equal to 0.2 and less than or equal to 3, thereby a thickness uniformity of the backside-metal layer is improved.
