Compositions containing iron, buffering agent and denatured protein have been prepared that are capable of increasing serum iron in a subject. For example, spray dried microbeads have been prepared containing iron entrapped within a protein matrix and unbound iron in a buffered composition that provides a gastroprotective effect, preserves iron in the more available Fe2+ form and improves iron bioavailability in humans relative to previously known vehicles for delivering iron to a subject.
Embodiment techniques map parity bits to sub-channels based on their row weights. The row weight for a sub-channel may be viewed as the number of "ones" in the corresponding row of the Kronecker matrix or as a power of 2 with the exponent (i.e. the hamming weight) being the number of "ones" in the binary representation of the sub-channel index (further described below). In one embodiment， candidate sub-channels that have certain row weight values are reserved for parity bit (s). Thereafter, K information bits may be mapped to the K most reliable remaining sub-channels, and a number of frozen bits (e.g. N-K) may be mapped to the least reliable remaining sub-channels. Parity bits may then mapped to the candidate sub-channels, and parity bit values are determined based on a function of the information bits.

Various examples provide a method of caching service data in LTE networks. A base station parses a data request received from a UE to obtain an identification of requested contents, judges whether the requested contents are cached in the base station, sends the contents to the UE in response to a determination that the requested contents are cached in the base station. In response to a determination that the requested contents are not cached in the base station, the base station judges whether the requested contents are cached in an adjacent base station, and obtains the contents from the adjacent base station and returns the contents to the UE in response to a determination that the requested contents are cached in the adjacent base station. In response to a determination that the requested contents are not cached in adjacent base stations, the base station forwards the data request to an SGW, and returns contents obtained from the SGW to the UE. Various examples also provide another method and apparatus of caching service data in an LTE network. According to the examples, data requests of UEs are not necessarily always forwarded to a business server. Instead, requested data is first sought from a cache (in a base station and/or an SGW) which is the closest to to the user to reduce transmission load of the LTE network, reduce the time delay in obtaining service data by users, and improve the quality of experience of users.
The present invention provides Genome-Scale T Cell Activity Arrays (GS-TCAA), as well as methods of making these arrays and methods of using them to identify immune modulators.
Provided are an Ag-CuO low-voltage contact material and a method for fabrication thereof, comprising a CuO frame having a porous structure, and a metallic silver material filling the CuO frame; the volume of said CuO frame occupies 40%-80% of the total volume of the low-voltage contact material, and the remainder is said metallic silver material.

An over-the-air (OTA) broadcast middleware unit is configured to receive aggregated session description data for a plurality of sessions, wherein each of the sessions transports media data related to common media content, and wherein each of the sessions is transmitted as part of an OTA broadcast, and extract at least some of the media data from the OTA broadcast based on the aggregated session description data. The OTA broadcast middleware unit may further deliver the extracted media data to a streaming client, such as a Dynamic Adaptive Streaming over HTTP (DASH) client.
An anomaly detection method for an internal virtual machine of a cloud system. State information about a normal virtual machine in a cloud system is collected to train a Hidden Semi-Markov Model (HsMM), and a corresponding algorithm is designed for detecting and computing probabilities and mahalanobis distances of resource dynamic change behaviour when various virtual machines in the cloud system are on line. If the mahalanobis distance in an on-line detection result of a certain virtual machine is greater than a pre-set threshold value, this indicates that an activity of the virtual machine is abnormal, so an anomaly detection and processing system in the cloud system is started for performing anomaly detection and processing on the virtual machine. If it is detected that an anomaly rate of a certain virtual machine is less than the maximum threshold value of the anomaly detection and processing, after an anomaly is eliminated, a warning prompt is sent to a cloud tenant of the virtual machine; and otherwise, an alarm is given to the cloud tenant of the virtual machine, and the virtual machine is shut down. According to the method, abnormal behaviour of an internal virtual machine of a cloud system can be detected in real time, and fewer system resources are occupied, thereby fully ensuring the high availability and security of an internal virtual machine of a cloud system.
An energy-storage lithium battery pack, comprising a casing, multiple batteries connected in series within the casing, a battery management module, a current-limiting module, a charging switch, a discharging switch, an air switch, a start-up switch, a communication connection port, and a power connector. The charging switch and discharging switch achieve control of charging and discharging of the batteries. The start-up switch and communication connection port are connected to the battery management module. The power connector connects positive and negative electrodes of the batteries. The current limiting module achieves a balance of a current of the lithium battery pack. The air switch provides secondary over-current protection to the lithium battery pack. The energy-storage lithium battery pack of the present invention can be used independently, and multiple battery packs can be connected in series to expand the capacity. In a series connection configuration, a host is automatically configured to communicate and interact with an upper level controller, and voltage consistency across the multiple battery packs is achieved by means of controlling the charging and discharging switches to be on or off, thus preventing a loop current, and preventing the battery packs from being damaged by an over-current condition.
The present invention relates to a resource release method, system, and device, and computer storage medium in a service function chain. The method comprises: a classifier constructs, upon detection of a flow being in a termination state, a flow release message packet carrying a flow release identifier and link information of the flow; the classifier sends, according to the link information, to a corresponding service function forwarder the flow release message packet; the service function forwarder forwards, according to the link information, to a corresponding function node the flow release message packet; and upon receiving the flow release message packet, the function node releases, according to the flow release identifier carried in the flow release message packet, a corresponding resource.
Disclosed is a session synchronization method based on instant copy between cluster nodes. Session identification information is stored in a client, thereby avoiding storing complete session information in the client, so as to prevent the potential security hazard of exposing user identity information; moreover, during a process of sending a request to a server by the client, only the session identification information, rather than the complete session information, is carried so that the transmitted data volume is greatly reduced, thereby improving the efficiency of accessing the server by the client. Session information synchronization between various cluster nodes does not need to acquire session information from a database, thereby avoiding the performance bottleneck caused by frequently using the database, and also does not need to use a dedicated session cache server, thereby reducing the development and deployment costs and having a good application prospect.
