galaxies represents one of the most exciting frontiers in astronomy.
Since the universe was filled with hydrogen atoms at early times, the
most promising method for observing the epoch of the first stars is
using the prominent 21-cm spectral line of hydrogen. This rich era of
early cosmic history should include several events caused by stellar
ultra-violet radiation and X-rays from early black holes. Work in this
field is growing rapidly in anticipation of the first 21-cm
observations. We have focused on predicting previously-unexpected
signatures of cosmic populations and on developing methods for a
model-independent analysis of upcoming data. -

New low frequency radio telescopes are being built to look back in time over 13 billion years, to when the Universe was less than a billion years old and the first stars and galaxies ignited (the so-called Epoch of Reionisation: EoR). This is the last remaining unexplored period of cosmic history and holds the key that connects the Cosmic Microwave Background and what we know about the Universe around us today. I will describe one of these new telescopes, the Murchison Widefield Array (MWA), built and operating in outback Western Australia. I'll outline some of the engineering considerations for the MWA, the EoR key science project, and other recent MWA science re-sults. The MWA is a precursor for a much larger project called the Square Kilometre Array (SKA), a billion dollar scale instrument. I'll describe the path from the MWA to the SKA over the next decade, including a significant upgrade to the MWA that is currently underway. -

Benoziyo Building Room 113Abstract Show full text abstract about Recalling unrelated memory items is a challenging task for m...» Recalling unrelated memory items is a challenging task for most people. In the classical free recall paradigm, participants are asked to repeat a list of randomly assembled words in an arbitrary order. For lists as short as five words, people begin to make recall mistakes, and for longer lists the fraction of recalled words is steadily decreasing. The variability of recall performance across participants is very large, but its origins, and in particular the potential contribution of practice, are not clear. In this study, we explored whether more and less successful participants exhibit different patterns of recall and whether this pattern changes over the course of the experiment. To this end, we analyzed a large data set of immediate free recall collected in the lab of M. Kahana (UPenn). We found that some participants exhibited extremely high recall performance, including many trials where they recalled completely the full presented lists of 16 words (‘perfect trials’). Moreover, these trials were typically characterized by a robust application of input-position dependent recall strategies; most prominently a serial ordering or a number of chunking strategies where presented lists were recalled in groups of consecutively positioned words. The number of perfect trials increased dramatically with practice, accompanied by a general increase in the extent of positional grouping applied by participants; however the choice of a particular strategy and the time course of its acquisition were highly variable among participants. Our results show, for the first time, that practicing memory recall results in improved performance, and that there are multiple ways humans can adopt to achieve perfect recall. -

Soft Matter and BiomaterialsContact Details Show full text description of Traction force microscopy (TFM) is a method that has been ut...» Traction force microscopy (TFM) is a method that has been utilized in the last decade to evaluate the forces applied by cells to underlying gels. Cells utilize traction forces to adhere, move, and apply force to their environment, as part of their normal function. Variation in forces between different cell types, following treatment, or following onset of disease and can reveal dynamic structural changes within the cell that may relate to changes in cell function. The mechanical interaction of cells with their environment depends on the cell type, its current activity, and the dimensionality and stiffness of the gel. Using 2-dimensional (2D), elastic polyacrylamide gels, with fluorescent particles embedded under their surface, or 3D collagen gels with dispersed particles, we are able to quantitatively evaluate forces applied by cells. In the current talk, I will explain the TFM method and approach in 2D and in 3D gel systems, providing detailed examples from three different cell types. I will provide examples on (1) invasive cancer cells (in 2D and 3D), showing differences between cancer and benign cells (2) changes in cell-gel interactions when undifferentiated stem cells grow into a 3D embryoid body; and (3) differences between pre-adipose cells and differentiated adipocytes. The experiments highlight quantitative similarities and differences relating to cell function and activity. -

We examined the relation between the stable synchronized activity modes and network connectivity using a Hodgkin-Huxley based, brain dynamics model. Simulations indicate that small motifs exhibit different synchronization modes depending on their local parameters. Thus the activity of a complex network composed of interconnected motifs cannot be extracted from the activity mode of each individual motif and is governed by local parameters. We demonstrate that the mechanism governing the synchronized activity modes in neural networks is the greatest common divisor of network loops. The synchronized mode and the transients to synchronization pinpoint the type of external stimuli. These analytic results are supported by in vitro experiments on cultured cortical cells, simulations of neural networks, simulations of chaotic maps, self-consistent and mixing arguments as well as analytical solutions of Bernoulli maps. Our findings call for reexamining sources of correlated activity in cortex and its functions. -

Proteins are an indispensable part of the cell’s content, and are synthesized by ribosomes. In particular, ribosomes synthesize ribosomal proteins – i.e., their own building blocks. And so, if a cell is to double, ribosomes are to double themselves as they double the proteome. Theoretical limits on the doubling time of cells, and on the required fraction of ribosomal proteins in the proteome, follow. We show that these limits are sensitive to coarse features of the ribosome, and present an array of evidence for their formative power on ribosome architecture in numerous organisms and in organelles. -
