Abstract: Technologies are described to increase a data limit for a user by introducing additional archive mailboxes as the original archive fills up or subsequently added archive mailboxes fill up. Thus, a user's data limit may be effectively removed through the use of additional archive mailboxes. In some examples, the additional mailboxes may be integrated into the architecture of the communication application such that their use is transparent to the user and/or an administrator of the communication application or associated service through the use of an application programming interface (API) that exposes a single multivalued strongly typed collection instead of dealing with multiple attributes and extending the schema every time a new type needs to be added. A mailbox locations attribute may act as the main storage of serialized mailbox locations and a mailbox identifier attribute may be used for indexing.

Abstract: Apparatus and associated methods relate to using a high learning rate to speed up the training of a receiver and switching from a high learning rate to a low learning rate for fine tuning based on exponentially weighted moving average convergence. In an illustrative example, a selection circuit may switch the high learning rate to the low learning rate based on a comparison of a moving average difference en to a predetermined stability criteria T1 of the receiver. The moving average difference en may include an exponentially weighted moving average of a difference between two consecutive exponentially weighted moving averages of an operation parameter un of the signal communication channel. By using this method, the training time for the receiver may be advantageously reduced.

Abstract: When routing light on photonic integrated circuit (PIC) chips optical back-reflection and scattering can be highly detrimental to the desired application. Unused ports of optical devices, such as MMI, DC, Y-junction, PD, etc. are a cause for back-reflection and scattering, whereby the scattered light could get picked up by adjacent components, e.g. photodetectors. Management of stray light on the PIC is needed to prevent the undesired coupling between various components and to reduce noise. A dump taper may be used to guide and scatter stray light away from sensitive components or fully absorb the light while maintaining very low reflection from the taper. A doped dump taper may be used to passively absorb light reaching the unused port, thereby eliminating unwanted reflection and scattering. Alternatively, an undoped taper may be used to scatter light away from sensitive components while maintaining very low back-reflection.

Abstract: A data storage medium may have increased data capacity by being configured with first and second patterned pedestals that are each separated from a substrate by a seed layer. A first polymer brush layer can be positioned between the first and second patterned pedestals atop the seed layer and a second polymer brush layer may be positioned atop each patterned pedestal. The first and second polymer brush layers may be chemically different and a block copolymer can be deposited to self-assemble into separate magnetic domains aligned with either the first or second polymer brush layers.

Abstract: Methods are provided for fabricating void-free metallic interconnect structures with self-formed diffusion barrier layers. A seed layer is deposited to line an etched opening in a dielectric layer. A metallic capping layer is selectively deposited on upper portions and upper sidewall surfaces of the seed layer which define an aperture into the etched opening. An electroplating process is performed to plate metallic material on exposed surfaces of the seed layer within the etched opening, which are not covered by the capping layer to form a metallic interconnect. The capping layer prohibits plating of metallic material on the capping layer and closing the aperture before the electroplating process is complete. A thermal anneal process is performed to cause the metallic material of the metallic capping layer to diffuse though the metallic interconnect and create a self-formed diffusion barrier layer between the metallic interconnect and the surfaces of the etched opening.
