Patent number: 9315831Abstract: Provided herein are compositions and methods related to the direct conversion of the starch in a ground or fractionated grain into a fermentable sugar feedstock capable of serving as a carbon source for the industrial production of one or more products by a fermenting organism, such as isoprene, isoprenoid precursor molecules, and/or isoprenoids. Such conversions may be performed at temperatures at or below the initial gelatinization temperature of the starch present in the grain and may utilize one or more isolatable endogenous enzymes present in certain unrefined grains.Type: GrantFiled: March 13, 2013Date of Patent: April 19, 2016Assignees: DANISCO US INC., THE GOODYEAR TIRE & RUBBER COMPANYInventors: Collette M.

Publication number: 20150304889Abstract: Embodiments of the present application provide a load balancing method and a network control node. An entity in which a serving cell is located selects a scheduling cell for an edge UE, and instructs the scheduling cell to allocate a data channel for the edge UE, and a control channel is retained in the serving cell and is not handed over. In this way, in a case of being transparent to the UE, an objective of load balancing is achieved by automatic fast coordinating and scheduling without handover. It can be seen that, in the foregoing load balancing manner, a data channel is used as transferring granularity, and a handover time delay does not need to be introduced, thereby implementing a function of fast balancing instantaneous load, and improving load balancing efficiency.Type: ApplicationFiled: June 30, 2015Publication date: October 22, 2015Inventors: Ying QIAN, Yusun FU, Yuzhong WU, Jingbo PENG

Patent number: 8951764Abstract: Embodiments of the present disclosure relate to a process for producing isoprenoid precursor molecules and/or isoprenoids from a starch substrate by saccharification and/or fermentation. The saccharification is effectively catalyzed by a glucoamylase at a pH in the range of 5.0 to 8.0. At a pH of 6.0 or above, the glucoamylase possesses at least 50% activity relative to its maximum activity. The saccharification and fermentation may be performed as a simultaneous saccharification and fermentation (SSF) process.Type: GrantFiled: August 3, 2012Date of Patent: February 10, 2015Assignee: Danisco US Inc.Inventors: Martien H.

Patent number: 8908551Abstract: The invention provides a self-adaptive downlink power control scheme for OFDMA-based wireless cellular networks suitable for noise-limited environments. Downlink power levels are assigned in a distributed manner in the absence of any requirement for coordination or cooperation between cells. Distributed assignment allows for more optimal usage of the available transmit power at the base stations and more complete exploitation of the flexibility of frequency domain scheduling. In one embodiment, base stations in a cellular network service mobile user equipment within the respective base station coverage areas, and categorize the user equipment in a plurality of power levels according to certain criteria in accordance with such factors as channel experience and quality. A load-balancing self-adjustment mechanism allows automatic balancing of the load between different power levels.Type: GrantFiled: September 25, 2012Date of Patent: December 9, 2014Assignee: Futurewei Technologies, Inc.Inventors: Amine Maaref, Ying Qian, Hadi Baligh, Jianglei Ma

Patent number: 8817723Abstract: A method of resource allocation for use in a wireless network is disclosed. A network coloring decision to assign a plurality of resource blocks to a plurality of cells within the wireless network is triggered upon occurrence of a network event. A network coloring is performed by assigning each cell of the plurality of cells a resource block from the plurality of resource blocks. An effect of interference among adjacent cells with a same resource block assignment is reduced as measured by a network performance metric related to a number of resource block assignment conflicts over the plurality of cells.Type: GrantFiled: November 17, 2011Date of Patent: August 26, 2014Assignee: Futurewei Technologies, Inc.Inventors: Mohammadhadi Baligh, Ying Qian
