Abstract: A manufacturing method of a turbomachine airfoil, such as an outlet guide vane airfoil, comprising positioning a first fibrous wall preform on a first mold portion, placing at least one core on the first wall preform, positioning a second fibrous wall preform on the core, assembling a second mold portion to the first mold portion so as to form a mold around the first and second wall preforms, applying a hardening treatment to the first and second wall preforms, removing the core, and positioning a reinforcing structure between the first wall preform and the second wall preform.

Abstract: Embodiments relate to synchronizing Internet Group Management Protocol (IGMP) leave processing in a system. One embodiment includes a system with a first access switch, a first virtual switch having a first timer, and a second virtual switch having a second timer. The first virtual switch and the second virtual switch are connected with the first access switch. The first access switch transmits an IGMP leave message to the first virtual switch. The first virtual switch transmits a synchronization message to the second virtual switch. The second virtual switch updates the second timer based on receiving the synchronization message.

Abstract: In one embodiment, a system includes at least one local processor adapted for executing logic, logic adapted for receiving a packet from an access switch on a virtual link aggregation (vLAG) port of a first switch, logic adapted for modifying a source media access control (MAC) address of the packet to include a MAC address of the first switch, wherein a last byte of the modified source MAC address includes a trunk identifier of the vLAG port on which the packet was received, and logic adapted for forwarding the packet to an inter-switch link (ISL) port. Other systems, methods, and computer program products are presented according to more embodiments.

Abstract: There is provided herein a method and apparatus suitable for use in studying cell membrane related activities. Activities of interest include patch-clamp related studies of networks of cells on a solid substrate. Cells are grown, preferably in a patterned manner, on a substrate having microholes therein. Seals between the cells and the microholes are formed. Each microhole is attached to a channel. In many cases only one hole will be attached to a single channel, allowing examination of effects of a stimulus at a number of different points in a network of one or more cell types. This may be interest, for example, to those wishing to study interactions between neurons or neuromuscular junctions.
