81. Marcadores de vulnerabilidad para la conducta suicida en el trastorno bipolar - Jiménez Martínez, Ester
Los pacientes bipolares presentan tasas muy elevadas de conductas suicidas. Dado que el litio, uno de los fármacos más ampliamente utilizado para tratar el trastorno bipolar, ha demostrado presentar ciertas propiedades antisuicidas y antiimpulsivas, pretendemos analizar el impacto que la variabilidad genética en algunos de los genes implicados en algunas de las vías relacionadas con el mecanismo de acción del litio ejerce sobre la conducta suicida, así como en los niveles de impulsividad, dimensión considerada tradicionalmente como un potencial endofenotipo de la conducta suicida. Además, habiéndose establecido una asociación entre un peor nivel de funcionamiento y la historia de conducta...

82. Radicalización del nacionalismo chino moderno: orígenes y desarrollo del fascismo chino. El caso de las organizaciones fascistas del Guomindang: la Sociedad Lixingshe y el Movimiento de la Nueva Vida (1927-1937) - Chen, Chiao-In
¿Ha existido en realidad el fascismo chino? Cuando hablamos de fascismo chino tenemos que hacer referencia necesariamente a una organización política conocida con varios nombres distintos: el nombre más común fue el de Camisas Azules (lanyishe) que fue utilizado en las prensa internacional durante los año treinta, aunque también se conoció por su nombre oficial, Sociedad de la Práctica Rigurosa de los Tres Principios del Pueblo (sanminzhuyi lixingshe o simplemente lixingshe). Lógicamente los Camisas Azules fue la expresión más conocida del fascismo chino, aunque no fue la única, sí fue la más relevante. Más su desarrollo y características e importancia,...

83. Flow Solver for Incompressible 2-D Drive Cavity - Kalb, Virginia L.
This software solves the Navier-Stokes equations for the incompressible driven cavity flow problem. The code uses second-order finite differencing on a staggered grid using the Chorin projection method. The resulting intermediate Poisson equation is efficiently solved using the fast Fourier transform. Time stepping is done using fourth-order Runge-Kutta for stability at high Reynolds numbers. Features include check-pointing, periodic field snapshots, ongoing reporting of kinetic energy and changes between time steps, time histories at selected points, and optional streakline generation.

84. Enhanced Reporting of Mars Exploration Rover Telemetry - Leger, Chris; Biesiadecki, Jeffrey J.; Maimone, Mark W.; Carsten, Joseph L.; Liebersbach, Robert T.
Mars Exploration Rover Enhanced Telemetry Extraction and Reporting System (METERS) is software that generates a human-readable representation of the state of the mobility and arm-related systems of the Mars Exploration Rover (MER) vehicles on each Martian solar day (sol). Data are received from the MER spacecraft in multiple streams having various formats including text messages, sparsely-sampled engineering quantities, images, and individual motor-command histories.

85. Implementation of Speed Variation in the Structural Dynamic Assessment of Turbomachinery Flow-Path Components - Brown, Andrew M.; DeHaye, Michael K.; Davis, R. Benjamin
During the design of turbomachinery flow path components, the assessment of possible structural resonant conditions is critical. Higher frequency modes of these structures are frequently found to be subject to resonance, and in these cases, design criteria require a forced response analysis of the structure with the assumption that the excitation speed exactly equals the resonant frequency. The design becomes problematic if the response analysis shows a violation of the HCF criteria. One possible solution is to perform "finite-life" analysis, where Miner's rule is used to calculate the actual life in seconds in comparison to the required life. In this...

87. Parametric Thermal Soak Model for Earth Entry Vehicles - Agrawal, Parul; Doan, Quy D.; Samareh, Jamshid
The analysis and design of an Earth Entry Vehicle (EEV) is multidisciplinary in nature, requiring the application many disciplines. An integrated tool called Multi Mission System Analysis for Planetary Entry Descent and Landing or M-SAPE is being developed as part of Entry Vehicle Technology project under In-Space Technology program. Integration of a multidisciplinary problem is a challenging task. Automation of the execution process and data transfer among disciplines can be accomplished to provide significant benefits. Thermal soak analysis and temperature predictions of various interior components of entry vehicle, including the impact foam and payload container are part of the solution...

88. Reply to ''Comments on 'Why Hasn't Earth Warmed as much as Expected?''' - Kahn, Ralph A.; Rodhe, Henning; Schwartz, Stephen E.; Ogren, John A.; Charlson, Robert J.
In response to our article, Why Hasnt Earth Warmed as Much as Expected? (2010), Knutti and Plattner (2012) wrote a rebuttal. The term climate sensitivity is usually defined as the change in global mean surface temperature that is produced by a specified change in forcing, such as a change in solar heating or greenhouse gas concentrations. We had argued in the 2010 paper that although climate models can reproduce the global mean surface temperature history over the past century, the uncertainties in these models, due primarily to the uncertainty in climate forcing by airborne particles, mean that the models lack...

89. Insights into Collisional between Small Bodies: Comparison of Impacted Magnesium-rich Minerals - Strojia, C.; Lindsay, S. S.; Keller, L. P.; Lederer, Susan M.; Jensen, E. A.; Smith, D. C.; Nakamura-Messenger, K.; Wooden, D. H.; Zolensky, M. E.; Cintala, M. J.; Berger, E. L.
Impacts are sustained by comets and asteroids throughout their lives, especially early in the Solar system's history, as described by the Nice model. Identifying observable properties that may be altered due to impacts can lead to a better understanding their collisional histories. Here, we investigate spectral effects and physical shock features observed in infrared spectra and Transmission Electron Microscope (TEM) images, respectively, of magnesium-rich minerals subjected to shock through impact experiments. Samples of magnesium-rich forsterite (Mg2SiO4, olivine), orthoenstatite (Mg2SiO3, pyroxene), diopside (MgCaSi2O6, monoclinic pyroxene), and magnesite (MgCO3, carbonate) were impacted at speeds of 2.4 km/s, 2.6 km/s and 2.8 km/s....

90. Development of the Code RITRACKS - Plante, Ianik; Cucinotta, Francis A.
A document discusses the code RITRACKS (Relativistic Ion Tracks), which was developed to simulate heavy ion track structure at the microscopic and nanoscopic scales. It is a Monte-Carlo code that simulates the production of radiolytic species in water, event-by-event, and which may be used to simulate tracks and also to calculate dose in targets and voxels of different sizes. The dose deposited by the radiation can be calculated in nanovolumes (voxels). RITRACKS allows simulation of radiation tracks without the need of extensive knowledge of computer programming or Monte-Carlo simulations. It is installed as a regular application on Windows systems. The...

91. The Mission Accessible Near-Earth Objects Survey (MANOS) - Thomas, Cristina; Polishook, David; Willman, Mark; Busch, Michael; Trilling, David; Abell, Paul; Person, Michael; Grundy, Will; Roe, Henry; DeMeo, Francesca; Moskovitz, Nicholas; Binzel, Richard; Christensen, Eric; Endicott, Thomas
NearEarth objects (NEOs) are essential to understanding the origin of the Solar System. Their relatively small sizes and complex dynamical histories make them excellent laboratories for studying ongoing Solar System processes. The proximity of NEOs to Earth makes them favorable targets for space missions. In addition, knowledge of their physical properties is crucial for impact hazard assessment. However, in spite of their importance to science, exploration, and planetary defense, a representative sample of physical characteristics for subkm NEOs does not exist. Here we present the Mission Accessible NearEarth Objects Survey (MANOS), a multiyear survey of subkm NEOs that will provide...

92. Turbulent Statistics From Time-Resolved PIV Measurements of a Jet Using Empirical Mode Decomposition - Dahl, Milo D.
Empirical mode decomposition is an adaptive signal processing method that when applied to a broadband signal, such as that generated by turbulence, acts as a set of band-pass filters. This process was applied to data from time-resolved, particle image velocimetry measurements of subsonic jets prior to computing the second-order, two-point, space-time correlations from which turbulent phase velocities and length and time scales could be determined. The application of this method to large sets of simultaneous time histories is new. In this initial study, the results are relevant to acoustic analogy source models for jet noise prediction. The high frequency portion...

93. Geologic Interpretation of Data Sets Collected by Planetary Analog Geology Traverses and by Standard Geologic Field Mapping - Evans, Cynthia A.; Feng, Wanda; Hurwitz, Debra M.; Gruener, John; Whitson, Peggy; Skinner, J. A., Jr.; Bleacher, Jacob F.; Eppler, Dean B.; Janoiko, Barbara
Geologic maps integrate the distributions, contacts, and compositions of rock and sediment bodies as a means to interpret local to regional formative histories. Applying terrestrial mapping techniques to other planets is challenging because data is collected primarily by orbiting instruments, with infrequent, spatiallylimited in situ human and robotic exploration. Although geologic maps developed using remote data sets and limited "Apollo-style" field access likely contain inaccuracies, the magnitude, type, and occurrence of these are only marginally understood. This project evaluates the interpretative and cartographic accuracy of both field- and remote-based mapping approaches by comparing two 1:24,000 scale geologic maps of the...

94. What Are Space Exposure Histories Telling Us about CM Carbonaceous Chondrites? - Nishiizumi, K.; Ross, K.; Le, L.; Imae, N.; Takenouchi, A.; Zolensky, Michael E.; Caffee, M.; Mikouchi, T.; Zolensky, P.; Velbel, M. A.; Yamaguchi, A.
Chondrites are chemically primitive and carbonaceous (C) chondrites are potentially the most primitive among them because they mostly escaped thermal metamor-phism that affected the other chondrite groups and ratios of their major, non-volatile and most of the volatile elements are similar to those of the Sun. Therefore, C chondrites are ex-pected to retain a good record of the origin and early history of the solar system. Carbonaceous chondrites are chemically differentiated from other chondrites by their high Mg/Si ratios and refractory elements, and have experienced various degrees of aqueous alteration. They are subdivided into eight subgroups (CI, CM, CO, CV,...

95. Are Medications Involved in Vision and Intracrancial Pressure Changes Seen in Spaceflight? - Faust, K. M.; Wotring, V. E.
The Food and Drug Association Adverse Event Reports (FDA AER) from 2009-2011 were used to create a database from millions of known and suspected medication-related adverse events among the general public. Vision changes, sometimes associated with intracranial pressure changes (VIIP), have been noted in some long duration crewmembers. Changes in vision and blood pressure (which can subsequently affect intracranial pressure) are fairly common side effects of medications. The purpose of this study was to explore the possibility of medication involvement in crew VIIP symptoms. Reports of suspected medication-related adverse events may be filed with the Food and Drug Administration (FDA)...

96. What are the Progenitors of Compace, Massive, Quiescent Galaxies at z (equals) 2.3? The Population of Massive Galaxies at z (greater than) 3 From NMBS AND CANDELS - Stefanon, Mauro; Rudnick, Gregory H.; Marchesini, Danilo; Tease, Katherine Whitaker; Brammer, Gabriel B.
Using public data from the NEWFIRM Medium-Band Survey (NMBS) and the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS), we investigate the population of massive galaxies at z > 3. The main aim of this work is to identify the potential progenitors of z 2 compact, massive, quiescent galaxies (CMQGs), furthering our understanding of the onset and evolution of massive galaxies. Our work is enabled by high-resolution images from CANDELS data and accurate photometric redshifts, stellar masses, and star formation rates (SFRs) from 37-band NMBS photometry. The total number of massive galaxies at z > 3 is consistent with the...

97. Cool-flame Extinction During N-Alkane Droplet Combustion in Microgravity - Williams, Forman A.; Nayagam, Vedha; Hicks, Michael C.; Dietrich, Daniel L.
Recent droplet combustion experiments onboard the International Space Station (ISS) have revealed that large n-alkane droplets can continue to burn quasi-steadily following radiative extinction in a low-temperature regime, characterized by negative-temperaturecoefficient (NTC) chemistry. In this study we report experimental observations of n-heptane, n-octane, and n-decane droplets of varying initial sizes burning in oxygen/nitrogen/carbon dioxide and oxygen/helium/nitrogen environments at 1.0, 0.7, and 0.5 atmospheric pressures. The oxygen concentration in these tests varied in the range of 14% to 25% by volume. Large n-alkane droplets exhibited quasi-steady low-temperature burning and extinction following radiative extinction of the visible flame while smaller droplets burned...
