Title: Method and device for generating a scalable data stream and method and device for decoding a scalable data stream with provision for a bit savings bank function
Inventor: SPERSCHNEIDER RALPH
IPC: G10L19/14
Filed: 2002-01-14
Abstract: In a method for generating a scalable data stream from one or several blocks of output data of a first encoder and from one or several blocks of output data of a second en-coder a determining data block for a current section of an input signal is written. In addition, output data of the second encoder representing a preceding section of the in-put signal are written in transmission direction from an encoder to a decoder after the determining data block.  When the output data of the second encoder are written for a preceding section of the input signal, the output data of the second encoder are written representing the current section of the input signal. In order to signalize where the output data of the second encoder for the preceding section end and where the output data of the second en-coder for the current section begin, buffer information is written into the scalable data stream. By the fact that output data of a preceding section follow a determining data block for the current section, a bit savings bank function may be implemented in the scalable encoder and simply be signalized in the bit stream.

Title: Inhibition of erk to reduce or prevent tolerance to and dependence on opioid analgesics
Inventor: GUTSTEIN HOWARD B
IPC: A61K38/45
Filed: 2002-01-25
Abstract: Inhibition of mitogen-activated protein kinases (MAPKs), or more particularly extracellular signal regulated kinases (ERKs) inhibits the development of tolerance to opioid analgesics. Therefore, methods for reducing tolerance, reducing the risk of physical dependence, reducing hyperalgesia, reducing the symptoms of opioid withdrawal or inhibiting pain sensitization are described.  MAPK inhibition at the spinal level represents a powerful treatment modality for chronic pain, blocking both neural sensitization induced by pain and factors limiting the effectiveness of opioids, the strongest analgesics currently in use to treat chronic pain.

Abstract: The invention, when incorporated in a drill-through modeling tool (DMT) , allows all the elements affecting drill-through behavior to be aggregated in a single structure or set of structures, thereby allowing administration to be simplified, and also permitting easier integration with third-party tools. T he invention also provides for graphical displays of drill-through paths for a DMT user. These displays show the parameters and dependencies of each drill- through path and allow tool users to obtain a quick overview of the drill- through network and further, they allow the tool user to confirm drill-through dependencies at a glance. Drill-through objects may thus be manipulated and maintained in a graphical manner.

Title: Verifiable secret shuffles and their application to electronic voting
Inventor: NEFF ANDREW C
IPC: H04L9/30
Filed: 2002-03-25
Abstract: We present a mathematical construct which provides a cryptographic protocol to (verifiably shuffle) a sequence of (k) modular integers, and discuss its application to secure, universally verifiable, multi-authority election schemes. The output of the shuffle operation is another sequence of (k) modular integers, each of which is the same secret power of a corresponding input element, but the order of elements in the output is kept secret. Though it is a trivial matter for the "shuffler" (who chooses the permutation of the elements to be applied) to compute the output from the input, the construction is important because it provides a linear size proof of correctness for the output sequence (i.e. a proof that it is of the form claimed) that can be checked by one or more arbitrary verifiers. The protocol is shown to be honest-verifier zeroknowledge in a special case, and is computational zeroknowledge in general. On the way to the final result, we also construct a generalization of the well known Chaum-Pedersen protocol for knowledge of discrete logarithm equality ([3], [2]). In fact, the generalization specializes (exactly) to the Chaum-Pedersen protocol in the case (k)=2. This result may be of interest on its own. An application to electronic voting is given that matches the features of the best current protocols with significant efficiency improvements. An alternative application to electronic voting is also given that introduces an entirely new paradigm for achieving (Universally Verifiable) elections.
