Abstract: A circuit includes a differential amplifier having a folded cascode architecture with a pair of cascode transistors. A sensing circuit senses a common mode input voltage of a differential input signal applied to the differential amplifier. A bias generator circuit generates a bias voltage for application to the pair of cascode transistors in the folded cascode architecture. The bias generator circuit is connected to an output of the sensing circuit such that the generated bias voltage has a value which is dependent on the sensed common mode input voltage. This dependence stabilizes a common mode output voltage from the differential amplifier in response to changes in the common mode input voltage.

Abstract: Techniques for providing extensibility framework for processing network packets are described herein. In one embodiment, in response to a packet received at a network element, the packet is processed using a generic process for performing a first type of operations required by the packet, wherein the first type of operations is common to a type of the packet. An extended process is invoked, via an extensibility application programming interface (API), to perform a custom operation that is not common to the generic process and is not statically known to the generic process, in order to determine whether the packet is eligible to access a resource of at least one of a plurality of application servers of a datacenter, including a layer-7 access control process. The network element operates as an application service gateway for the datacenter. Other methods and apparatuses are also described.

Abstract: A new method of inactivating enveloped viruses and preparations useful in accomplishing this inactivation are disclosed. The method is based on the discovery that paucilamellar lipid vesicles, preferably having non-phospholipids as their primary structural material, can fuse with enveloped virus and that the nucleic acid of the virus denatures shortly after the fusion. The method is useful for inactivating viruses such as orthomyxoviruses, paramyxoviruses, coronaviruses, and retroviruses.
