Surface exposure dating of boulders on an exceptionally well-preserved sequence of moraines in the Peruvian Andes reveals the most detailed record of glaciation heretofore recognised in the region. The high degree of moraine preservation resulted from dramatic changes in the flow path of piedmont palaeoglaciers at the southern end of the Cordillera Blanca (10° 00′ S, 77° 16′ W), which, in turn, generated a series of cross-cutting moraines. Sixty 10Be surface exposure ages indicate at least four episodes of palaeoglacier stabilisation (>65, ca. 65, ca. 32 and ca. 18-15 ka) and several minor advances or stillstands on the western side of the Nevado Jeulla Rajo massif. The absence of ages close to the global Last Glacial Maximum (ca. 21ka) suggests that if an advance culminated at that time any resulting moraines were subsequently overridden. The timing of expanded ice cover in the central Peruvian Andes correlates broadly with the timing of massive iceberg discharge (Heinrich) events in the North Atlantic Ocean, suggesting a possible causal connection between southward migration of the Intertropical Convergence Zone during Heinrich events and a resultant increase in precipitation in the tropical Andes. © 2010 John Wiley & Sons, Ltd.

Carbon nanotubes are a promising platform across a broad spectrum of applications ranging from separations technology, drug delivery, to bio(electronic) sensors. Proper dispersion of carbon nanotube materials is important to retaining the electronic properties of nanotubes. Experimentally it has been shown that salts can regulate the dispersing properties of CNTs in aqueous system with surfactants (Niyogi, S.; Densmore, C. G.; Doorn, S. K. J. Am. Chem. Soc.2009, 131, 1144-1153); details of the physicochemical mechanisms underlying such effects continue to be explored. We address the effects of inorganic monovalent salts (NaCl and NaI) on dispersion stability of carbon nanotubes.We perform all-atom molecular dynamics simulations using nonpolarizable interaction models to compute the potential of mean force between two (10,10) single-walled carbon nanotubes (SWNTs) in the presence of NaCl/NaI and compare to the potential of mean force between SWNTs in pure water. Addition of salts enhances stability of the contact state between two SWNTs on the order of 4 kcal/mol. The ion-specific spatial distribution of different halide anions gives rise to starkly different contributions to the free energy stability of nanotubes in the contact state. Iodide anion directly stabilizes the contact state to a much greater extent than chloride anion. The enhanced stability arises from the locally repulsive forces imposed on nanotubes by the surface-segregated iodide anion. Within the time scale of our simulations, both NaI and NaCl solutions stabilize the contact state by equivalent amounts. The marginally higher stability for contact state in salt solutions recapitulates results for small hydrophobic solutes in NaCl solutions (Athawale, M. V.; Sarupria, S.; Garde, S. J. Phys. Chem. B2008, 112, 5661-5670) as well as single-walled carbon nanotubes in NaCl and CaCl2 aqueous solutions. © 2012 American Chemical Society.

This paper argues that citizens are capable of developing and promoting complex policy symbols, and that these symbols include supporting frames that explain and justify them. Based on a long-term study of education policies in Los Angeles, California, the paper uses interpretive methods to reconstruct and analyze these frames. Citizens developed two specific policy symbols while the district was engulfed in a desegregation debate; citizens identified schools as places where students gained academic knowledge and as institutions that affected broader race relations. However, education policy in Los Angeles could not support these two symbols over a long period of time, and a political movement to end mandatory busing eventually caused the academic symbol (originally the weaker of the two symbols) to become dominant. This trend reflects broader national discussions, in which education is now discussed in terms of standards and accountability and is evidence of continuing racism in US policy. © 2010 Springer Science+Business Media, LLC.

This project is for support for US participants to participate in a workshop entitled, Mathematical Modeling of Tumor-Immune System Dynamics to be held in Sydney, Australia from January 7-10, 2013. The workshop aims at bringing together applied mathematicians, biologists, and clinicians actively working in the field of cancer immunology in order to share their current research and exchange ideas, as well as increasing awareness of the innovative mathematical tools that are available and suitable for the growing field of cancer immunology. The workshop will include keynote tutorials by leading experts in the field of cancer immunology, group discussions, poster sessions, senior/junior presentations, and a summary panel discussion. A major objective of this workshop is to explore opportunities for future collaborative interaction and educational exchange amongst cancer immunology practitioners across Asian Pacific and North American countries.
Recent progress in cancer immunology and the advances in immunotherapy suggest that the immune system plays a fundamental role in host defense against tumor, and could be utilized to prevent or cure cancer. The purpose of this workshop is to: (1) share new advances in the field of mathematical and computational models of tumor-immune dynamics, (2) catalyze and identify potential areas for future collaborative opportunities between US and Australian researchers in the field of the cancer immunology, (3) establish novel approaches for interdisciplinary research, data sharing and ways of applying computational approaches to cancer immunology, and (4) explore innovative methods of combining mathematical and computational modeling of biological processes with undergraduate and graduate student education.
This workshop includes US and international mathematicians, biologists and clinicians, and participation will catalyze new collaborations, and energize existing international collaborative research among these scientists. In particular, the workshop will involve junior researchers and students from Asian Pacific and North American countries, providing opportunities for new and early-career mathematicians and biologists to enter this fast growing interdisciplinary field of cancer immunology. To stimulate new interests in this kind of interdisciplinary work, the workshop will schedule a panel discussion on how to cultivate a sustained collaboration between US, Australian and international scientists. The workshop will also have an educational impact by providing training to graduate students, early-career scholars and clinicians in cancer-immune dynamics. This workshop will serve as a platform for facilitating interdisciplinary interactions between experienced and beginning researchers in tumor-immune dynamics. In addition, the workshop will identify opportunities for overseas training and exchange programs for US investigators and graduate students motivated by the challenging problems in cancer immunology in Australia and elsewhere. Five of the plenary speakers are female, and two of them are minority. The organizers plan to post lectures online, and publish proceedings in an internationally recognized journal in math biology.

The effects of water confined in regions between self-assembling entities is relevant to numerous contexts such as macromolecular association, protein folding, protein-ligand association, and nanomaterials self-assembly. Thus assessing the impact of confined water, and the ability of current modeling techniques to capture the salient features of confined water is important and timely. We present molecular dynamics simulation results investigating the effect of confined water on qualitative features of potentials of mean force describing the free energetics of self-assembly of large planar hydrophobic plates. We consider several common explicit water models including the TIP3P, TIP4P, SPC/E, TIP4P-FQ, and SWM4-NDP, the latter two being polarizable models. Examination of the free energies for filling and unfilling the volume confined between the two plates (both in the context of average number of confined water molecules and "depth" of occupancy) suggests TIP4P-FQ water molecules generally occupy the confined volume at separation distances larger than observed for other models under the same conditions. The connection between this tendency of TIP4P-FQ water and the lack of a pronounced barrier in the potential of mean force for plate-plate association in TIP4P-FQ water is explored by artificially, but systematically, populating the confined volume with TIP4P-FQ water at low plate-plate separation distances. When the critical separation distance [denoting the crossover from an unoccupied (dry) confined interior to a filled (wet) interior] for TIP4P-FQ is reduced by 0.5 Å using this approach, a barrier is observed; we rationalize this effect based on increased resistant forces introduced by confined water molecules at these low separations. We also consider the dynamics of water molecules in the confined region between the hydrophobes. We find that the TIP4P-FQ water model exhibits nonbulklike dynamics, with enhanced lateral diffusion relative to bulk. This is consistent with the reduced intermolecular water-water interaction indicated by a decreased molecular dipole moment in the interplate region. Analysis of velocity autocorrelation functions and associated power spectra indicate that the interplate region for TIP4P-FQ at a plate separation of 14.4 Å approaches characteristics of the pure water liquid-vapor interface. This is in stark contrast to the other water models (including the polarizable SWM4-NDP model). © 2012 American Physical Society.
