Research findings suggest that experience and cognitive strategies contribute to successful performance during perceptual-motor tasks. This article critically reviews selected literature on the effects of information-processing skills, preferred movement time, experience, and task difficulty on performance during coincident timing tasks. Theoretical information and research findings are discuss...

Cortical tremor (CT) is a form of cortical reflex myoclonus that can mimic essential tremor (ET). Clinical features that are helpful in distinguishing CT from ET are the irregular and jerky appearance of the movements. We report two patients with CT with coexisting orthostatic movements, either orthostatic tremor (OT) or myoclonus, who experienced functional improvement in both cortical myoclon...

We revisit an old problem in classical invariant theory, viz. that of giving algebraic conditions for a binary form to have linear factors with assigned multiplicities. We construct a complex of SL2–representations such that the desired algebraic conditions are expressible as a specific cohomology group of this complex.

[1] Previous studies have shown strong contrasting trends in annual sea ice duration and in monthly sea ice concentration in two regions of the Southern Ocean: decreases in the western Antarctic Peninsula/southern Bellingshausen Sea (wAP/sBS) region and increases in the western Ross Sea (wRS) region. To better understand the evolution of these regional sea ice trends, we utilize the full tempor...

Gravitational waves are excellent tools to probe the foundations of General Relativity in the strongly dynamical and non-linear regime. One such foundation is Lorentz symmetry, which can be broken in the gravitational sector by the existence of a preferred time direction, and thus, a preferred frame at each spacetime point. This leads to a modification in the orbital decay rate of binary system...
