Data is cached in a dual-controller storage array having a first cache controlled by a first controller, a second cache controlled by a second controller, and a shared array of persistent storage devices, such as disk drives. When one of the controllers receives a write request, it stores the data in persistent storage, stores a copy of that data in the first cache, and transmits identification data to the second controller that identifies the data written to persistent storage. Using the identification data, the second controller invalidates any data stored in the second cache that corresponds to the data that the first controller wrote to persistent storage. If a controller receives a read request, and the requested data is validly stored in its cache, the controller retrieves it from the cache; otherwise, the controller reads the requested data from persistent storage and caches a copy of the requested data.

A lease system is described herein that allows clients to request a lease to a remote file, wherein the lease permits access to the file across multiple applications using multiple handles without extra round trips to a server. When multiple applications on the same client (or multiple components of the same application) request access to the same file, the client specifies the same lease identifier to the server for each open request or may handle the request from the cache based on the existing lease. Because the server identifies the client's cache at the client level rather than the individual file request level, the client receives fewer break notifications and is able to cache remote files in more circumstances. Thus, by providing the ability to cache data in more circumstances common with modern applications, the lease system reduces bandwidth, improves server scalability, and provides faster access to data.

The system additionally executes standard AGC techniques to refine the gain for the first-time talker while the first-time talker continues speaking. When a steady state within a decibel threshold is attained using standard AGC for the first-time talker, the system stores the steady state gain for the first-time talker to storage. Upon identifying a previously-identified talker, the system retrieves from storage the steady state gain for the talker and applies the steady state gain to the audio stream.

To improve bioavailability of the catalytic metalloporphyrin-based SOD mimics Mn(III) 5,10,15,20-tetrakis[N-ethylpyridinium-2-yl]porphyrin (MnTE-2-PyP5+) and Mn(III) 5,10,15,20-tetrakis[N,N′-diethylimidazolium-2-yl]porphyrin (MnTDE-2-ImP5+), three new Mn(III) porphyrins, bearing oxygen atoms within side chains, were synthesized and characterized: Mn(III) 5,10,15,20-tetrakis[N-(2-methoxyethyl)pyridinium-2-yl]porphyrin (MnTMOE-2-PyP5+), Mn(III) 5,10,15,20-tetrakis[N-methyl-N′-(2-methoxyethyl)imidazolium-2-yl]porphyrin (MnTM,MOE-2-ImP5+) and Mn(III) 5,10,15,20-tetrakis[N,N′-di(2-methoxyethyl)imidazolium-2-yl]porphyrin (MnTDMOE-2-ImP5+). The catalytic rate constants for O2.− dismutation (and the related metal-centered redox potentials vs NHE) for the new compounds are: log kcat=8.04 (E1/2=+251 mV) for MnTMOE-2-PyP5+, log kcat=7.98 (E1/2=+356 mV) for MnTM,MOE-2-ImP5+ and log kcat=7.59 (E1/2=+365 mV) for MnTDMOE-2-ImP5+. At 30 μM levels none of the new compounds were toxic, and allowed SOD-deficient E. coli to grow nearly as well as wild type. At 3 μM levels, the MnTDMOE-2-ImP5+, bearing an oxygen atom within each of the eight side chains, was the most effective and offered much higher protection than MnTE-2-PyP5+, while MnTDE-2-ImP5+ was inefficient. These new porphyrins were compared to Mn(III) N-alkylpyridylporphyrins. While longer-chain n-alkyl members of the series exerted toxicity at higher concentration levels, they were very effective at submicromolar levels. Thus, 0.3 μM Mn(III) tetrakis(N-n-hexyl-pyridinum-2-yl)porphyrin and its n-octyl analogue offered the same level of protection as did ≧10 μM methyl and ethyl porphyrins. The kcat of methyl and n-octyl porphyrins are identical, but n-octyl is ˜10-fold more lipophilic. Therefore, the 30-fold improvement in bioavailability appears to be due to the increase in lipophilicity. MnTDMOE-2-ImP5+ and longer-chain Mn(III) N-alkylpyridylporphyrins may offer better treatment for oxidative stress injuries than the previously studied MnTE-2-PyP5+ and MnTDE-2-ImP5+.

A structure is adopted for a layout of an SRAM cell which provides a local wiring 3a between a gate 2a and gate 2b and connects an active region 1a and an active region 1b. This eliminates the necessity for providing a contact between the gate 2a and the gate 2b. Therefore, it is possible to reduce the size of a memory cell region C in a short side direction. Furthermore, a structure whereby a left end of a gate 2c is retreated from the gate 2a and a local wiring 3b which connects the active region 1b and gate 2c disposed in a diagonal direction is adopted. This allows the gate 2a to be shifted toward the center of the memory cell region C.
