Abstract: A system includes a memory and a processor communicatively coupled to the memory. The memory stores a correlation index that is based at least in part on a portfolio of index options, a plurality of stock options, and a plurality of deltas computed using a plurality of constant flat implied volatilities. The processor determines a value of the correlation index by selecting a plurality of strike prices for each of the index and stock options, computing a constant flat implied volatility for an index and a plurality of stocks on a first date, and computing the plurality of deltas using the plurality of constant flat implied volatilities.

Abstract: This disclosure describes implantable medical leads that include a lead body and an electrode. A width of the electrode as measured along a longitudinal direction of the lead varies about the perimeter of the lead. The uneven width of the electrode may bias a stimulation field in a particular direction, e.g., a radial or transverse direction relative to the longitudinal axis of the lead. Electrodes with an uneven width may be useful for controlling the direction of propagation of the stimulation field in order to, for example, avoid phrenic nerve stimulation during LV pacing or neck muscle stimulation during vagal neurostimulation.

Abstract: A bushing, having a core member, at least one enveloping body surrounding the same, and at least one elastic connecting layer, the elastic connecting layer joining together and spacing apart the enveloping body and the core member, and the core member and the enveloping body being movable relative to one another. In view of the object of designing and further refining a bushing of the type mentioned at the outset in such a way that it exhibits an adjustable stiffness response that is dependent on the deflection of the core member relative to the enveloping body, following the cost-effective manufacturing thereof, the bushing has at least one limit stop, which is structurally separate or is produced separately from the connecting layer, is assigned to the core member and/or the enveloping body and limits the relative movement thereof.

Abstract: A memory protection unit includes at least a first access control unit and a second access control unit programmed for controlling an access to a memory device. Further a method to operate a processing system comprising multiple processing devices and multiple memory protection units associated to the multiple processing devices, The access to the memory by a processing device is approved if first access control unit and second access control unit of the memory protection associated to the processing device approves the access and access is rejected if first access control unit or second access control unit rejects the access. The first access control unit is programmable by the associated processing device alone and the programming of the second access control unit is readable by an additional processing device which is to be used in a system with multiple programming devices, not the associate processing device.

Abstract: This disclosure describes techniques for controlling a depth of propagation of a stimulation field extending from an outer diameter of a lead body of an implantable stimulation lead. An implantable electrical stimulation lead may include a lead body, and at least one electrode arranged as a ring. An outer diameter of the ring may be different than an outer diameter of the lead body. A ring with a diameter smaller than the diameter of the lead body may be useful in limiting the depth of propagation of the stimulation field within patient tissue. A ring with a diameter greater than the diameter of the lead body may be useful in extending the depth of propagation of the stimulation field.

Abstract: The invention relates to a method for separating titanium tetrachloride and the hydrolyzed reaction products of titanium tetrachloride from the exhaust gases generated during the chlorination of raw materials containing titanium by treating the exhaust gases with a first aqueous hydrochloric-acid solution of titanium oxychloride, where, in the first separation stage (2), small droplets of hydrochloric-acid titanium oxychloride solution (3) are flowed with the exhaust gas flow, and larger droplets of hydrochloric-acid titanium oxychloride solution are flowed counter current to the exhaust to remove the smaller droplets and ensure that virtually no droplets are carried to a second separation stage. In the second separation stage, a second titanium oxychloride solution is injected into a second reactor (9), the second solution having a lower titanium oxychloride concentration than that injected in the first separation stage.

Abstract: Delivery of genetic material to a stimulation site causes transgene expression by tissue at the stimulation site. In some embodiments, the delivered genetic material causes increased expression of proteins, such as connexins, gap junctions, and ion channels, to increase the conductivity of the tissue at the stimulation site. In some embodiments, the delivered genetic material causes expression of a metalloproteinase, an anti-inflammatory agent, or an immunosuppressant agent. Genetic material is delivered to the stimulation site via a stimulation lead. A stimulation lead for delivering genetic material to a stimulation site includes a chamber that contains a polymeric matrix. The matrix absorbs the genetic material and elutes the genetic material to the stimulation site.
