Totally Implantable Bidirectional Neural Prostheses: A Flexible Platform for Innovation in Neuromodulation.

Implantable neural prostheses are in widespread use for treating a variety of brain disorders. Until recently, most implantable brain devices have been unidirectional, either delivering neurostimulation without brain sensing, or sensing brain activity to drive external effectors without a stimulation component. Further, many neural interfaces that incorporate a sensing function have relied on hardwired connections, such that subjects are tethered to external computers and cannot move freely. A new generation of neural prostheses has become available, that are both bidirectional (stimulate as well as record brain activity) and totally implantable (no externalized connections). These devices provide an opportunity for discovering the circuit basis for neuropsychiatric disorders, and to prototype personalized neuromodulation therapies that selectively interrupt neural activity underlying specific signs and symptoms

Israel\u27s Transboundary Water Disputes

As water is necessary to the function of life, it is imperative to understand the role of water in the politically turbulent Middle East. This paper will focus on Israel’s water disputes with her neighbors and how such disputes have either led to military confrontation, have been partially resolved, and otherwise continue to exist. As populations in the region are expected to increase, the need for water, already in short supply, will be magnified. Thus negotiations to settle water disputes and provide for equitable distribution of the water resources will become more contentious. This legal analysis of Israel’s water disputes will hopefully provide some guidance to the settlement of such issues in Israel’s future peace negotiations with the Syrians and Palestinians

Three axis attitude control system

A three-axis attitude control system for an orbiting body comprised of a motor driven flywheel supported by a torque producing active magnetic bearing is described. Free rotation of the flywheel is provided about its central axis and together with limited angular torsional deflections of the flywheel about two orthogonal axes which are perpendicular to the central axis. The motor comprises an electronically commutated DC motor, while the magnetic bearing comprises a radially servoed permanent magnet biased magnetic bearing capable of producing cross-axis torques on the flywheel. Three body attitude sensors for pitch, yaw and roll generate respective command signals along three mutually orthogonal axes (x, y, z) which are coupled to circuit means for energizing a set of control coils for producing torques about two of the axes (x and y) and speed control of the flywheel about the third (z) axis. An energy recovery system, which is operative during motor deceleration, is also included which permits the use of a high-speed motor to perform effectively as a reactive wheel suspended in the magnetic bearing

The Doctrine In The Shadows: Reverse-Erie, Its Cases, Its Theories, And Its Future With Plausibility Pleading In Alaska

In 2007 and 2009, respectively, the United States Supreme Court decided Bell Atlantic Corp. v. Twombly and Ashcroft v. Iqbal, abrogated Conley v. Gibson’s notice pleading standard, and imposed a new plausibility pleading standard upon the federal court system. Alaska, along with a majority of states however, still retains Conley’s “no set of facts” notice pleading standard. This Note asks, in light of the difference between the federal and Alaska pleading standards, whether Alaska—or any state—could be forced to apply the federal pleading standard when it adjudicates federal substantive claims. Prior to Iqbal, a plaintiff in Alaska would have faced the same pleading obligations in state and federal court regardless of whether he pleaded a state or federal claim. As this Note describes, now, a plaintiff could face different pleading standards depending on not only where he brings his claim, but also, if he’s in state court, whether he brings a state or federal claim. The reason for this is the Reverse-Erie doctrine: an little-developed judicial choice of law theory that broadly asks which procedure, federal or state, applies in a state court proceeding. Using the differences between federal and state pleading standards as an opportunity to flesh out Reverse-Erie, this Note concludes that while it is unlikely that the Supreme Court would force a state to adopt the federal pleading standard, the jurisprudential framework for such a move exists

Comparing coastal storm impact to decadal change in barrier island ecosystems

Highly dynamic coastal systems respond to disturbance events with a combination of topographic and vegetative changes. Sea level rise impacts on barrier islands have been quantified, but storm effects on vegetation are limited. Here we quantified barrier island vegetation change in response to an isolated storm event and compared to long-term periods. We hypothesized that disturbance-resisting areas with high woody vegetation cover and/or high foredune elevation would experience minimal transitions after a storm event, whereas disturbance-reinforcing areas with low vegetation cover and low foredune elevation would experience greater transitions between ecosystem states after a storm event. Patterns of dissonance were found at the island-scale, as net loss of woodland cover occurred during the storm and a net gain occurred through decadal regimes, indicative of a slow growing late successive vegetation responding to disturbance. Using sub-islands transects, significant correlations between stable upland vegetation covers (both woodland and grassland) and percent bare suggests that the amount of upland land cover may be important in upland community response to storm events. Maximum bare elevation was significantly correlated to woodland cover, indicative of disturbance resisting domains. Significant correlations found between pre-storm woodland cover (both area and percent) and non-changing grasslands suggest that the existence of woody vegetation is dependent on the establishment and extent of stable grasslands. No correlations were found with area of marshland converted to upland post storm. My results did not fully support my hypothesis but document upland vegetation interactions with elevation amidst a moderate coastal storm

On Individual Risk

We survey a variety of possible explications of the term "Individual Risk." These in turn are based on a variety of interpretations of "Probability," including Classical, Enumerative, Frequency, Formal, Metaphysical, Personal, Propensity, Chance and Logical conceptions of Probability, which we review and compare. We distinguish between "groupist" and "individualist" understandings of Probability, and explore both "group to individual" (G2i) and "individual to group" (i2G) approaches to characterising Individual Risk. Although in the end that concept remains subtle and elusive, some pragmatic suggestions for progress are made.Comment: 31 page
