Migration then assembly: Formation of Neptune mass planets inside 1 AU

We demonstrate that the observed distribution of `Hot Neptune'/`Super-Earth' systems is well reproduced by a model in which planet assembly occurs in situ, with no significant migration post-assembly. This is achieved only if the amount of mass in rocky material is $\sim 50$--$100 M_{\oplus}$ interior to 1 AU. Such a reservoir of material implies that significant radial migration of solid material takes place, and that it occur before the stage of final planet assembly. The model not only reproduces the general distribution of mass versus period, but also the detailed statistics of multiple planet systems in the sample. We furthermore demonstrate that cores of this size are also likely to meet the criterion to gravitationally capture gas from the nebula, although accretion is rapidly limited by the opening of gaps in the gas disk. If the mass growth is limited by this tidal truncation, then the scenario sketched here naturally produces Neptune-mass objects with substantial components of both rock and gas, as is observed. The quantitative expectations of this scenario are that most planets in the `Hot Neptune/Super-Earth' class inhabit multiple-planet systems, with characteristic orbital spacings. The model also provides a natural division into gas-rich (Hot Neptune) and gas-poor (Super-Earth) classes at fixed period. The dividing mass ranges from $\sim 3 M_{\oplus}$ at 10 day orbital periods to $\sim 10 M_{\oplus}$ at 100 day orbital periods. For orbital periods $< 10$ days, the division is less clear because a gas atmosphere may be significantly eroded by stellar radiation.Comment: 41 pages in preprint style, 15 figures, final version accepted to Ap

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

Early role of vascular dysregulation on late-onset Alzheimer's disease based on multifactorial data-driven analysis

Multifactorial mechanisms underlying late-onset Alzheimer's disease (LOAD) are poorly characterized from an integrative perspective. Here spatiotemporal alterations in brain amyloid-β deposition, metabolism, vascular, functional activity at rest, structural properties, cognitive integrity and peripheral proteins levels are characterized in relation to LOAD progression. We analyse over 7,700 brain images and tens of plasma and cerebrospinal fluid biomarkers from the Alzheimer's Disease Neuroimaging Initiative (ADNI). Through a multifactorial data-driven analysis, we obtain dynamic LOAD–abnormality indices for all biomarkers, and a tentative temporal ordering of disease progression. Imaging results suggest that intra-brain vascular dysregulation is an early pathological event during disease development. Cognitive decline is noticeable from initial LOAD stages, suggesting early memory deficit associated with the primary disease factors. High abnormality levels are also observed for specific proteins associated with the vascular system's integrity. Although still subjected to the sensitivity of the algorithms and biomarkers employed, our results might contribute to the development of preventive therapeutic interventions

Installation Movie Files

Video documentation of the installation of the exhibit in the Duderstadt Center.This project 's title refers to the writings of Antonin Artaud, who proposed a "Theater of Cruelty" in France during the 1930's. In his manifestos and his larger work "The Theater and Its Double", Artaud invoked a fundamentally sincere and "essential theater", which would abandon the confining norms of the contemporary "artistic spectacle" to create an immediate experience shared by actors and audience. The Problem: We live in a culture without shadows. We are unknowing participants in a continuous spectacle, resulting in experiences that are both anaesthetic and unreal. The theater, the television set, and the computer screen have inappropriately framed our signified experiences and removed us from them. Our reliance on visual culture has begun to impair our reception of information through the senses working as a whole. The Question: How can we use technology to regain our lost experience by making multiple modes of information reception possible simultaneously? How can the now static human body be repositioned in space as a moving, feeling entity? How can our senses be challenged, enhanced, or altered completely via technological mediation? How can the senses be reconnected and dangerously reconstructed? How can the senses be privileged, making signified experiences lived ones? Finding an Answer: We believe that haptics and synethesia coupled with rich media are the means by which we can redefine sensory information. Haptics refers to a psychological orientation of a person in space by means of touch instead of sight. Like a blind person using a cane to guide their passage down a sidewalk, the haptic sense can be extended. The cane, the automobile and the Segway© Human Transporter are all instances of this extension. We believe that all bodily senses can be combined and utilized in similar ways with new technologies, augmenting and transforming the experiences of both individuals and audiences. What if you could “feel” a shower of music instead of hearing it? What if you could taste shapes? What if all transcribed textual information, be it a musical score or literary text, could be interpreted through other sensory means working in combination with new media? Information once inaccessible to those with disabilities could be mediated through these other means. The Haptic Theater of Cruelty does not physically exact violence upon an audience. Instead, it inhabits an objective space, where technology is handled with ethos and participants are not merely observers. Our ultimate goal is to reconnect our audience to a lost humanity and a sense of memory that is kept through action, even violent action. The phenomenological and logical combine with rich media to create a “common sense”, a place where all of our senses meet with our collective consciousness to create holistic perception.GROCS: GRant Opportunities [collaborative spaces], a Digital Media Commons program to fund student research on the use of rich media in collaborative learning.http://deepblue.lib.umich.edu/bitstream/2027.42/60405/3/Hapticdocumentary.movhttp://deepblue.lib.umich.edu/bitstream/2027.42/60405/2/Haptic_Installation_Walkthrough.movhttp://deepblue.lib.umich.edu/bitstream/2027.42/60405/1/Arch Construction.mo
