Falls Lake Agent-based Model Critical Transitions Dataset
<p>Data files are provided here. They are output from the Falls Lake ABM at <a href="https://github.com/maskarb/FallsLakeABM">https://github.com/maskarb/FallsLakeABM</a>. Four management scenarios are simulated for 16 shifting climate scenarios. Management Scenario 1 is no management. Management Scenario 2 is retrofitting. Management Scenario 3 is retrofitting with light drought restrictions. Management Scenario 4 is retrofitting with severe drought restrictions. The 16 shifting climate scenarios correspond to shifting factors equal to 0.25 - 1.0, increasing in 0.05 increments. For each of the 64 settings (16 climate settings X 4 management scenarios), 100 simulations were run to capture stochasticity.</p> <p>Files in Results-mgmt-x folders show the agent-based modeling results for each simulation. Data files (for example, res-mgmt-1-s-0.25-5.txt) describe the storage and deficit for each of the simulations in million cubic meters, reported at a monthly timestep. Columns 5-9, inflow, storage, outflow, totalWaterSupply, waterSupply, report monthly flows. </p> <p>Files in EWS-mgmt-X-window-25 shows the value of each early warning signals indicator calculated for log-transformed reservoir storage for each of 100 simulations, for management strategies 1-4 and shifting factors. Winsize is set at 25%, which means that EWS indicators are not calculated until time step 300, or 25% of 1200 time steps.</p>
Trends and Transitions in 150 years of The American Naturalist
<p><span><span><span><span><span><span><span><span><span><span><span><i>The American Naturalist</i> recently passed its sesquicentennial. Throughout this long history, it regularly encountered moments of introspection and debate over its goals, mission, identity and audience. Here, we chronicle the history of those debates and transitions at critical moments. The <i>Naturalist </i>began as a popular magazine for amateur naturalists in the late 1860's. In the late 1870's it transitioned to an increasingly academic journal for professional scientists, from all branches of the natural sciences. By the turn of the century, academic specialization led to increasing fragmentation of the sciences into a multitude of societies and journals, creating an identity crisis for the once broad-reaching <i>American Naturalist.</i> This identity crisis was resolved when the journal pivoted around 1910 to focus on fundamental advances in the newly-emerging field of genetics. In the 1960's the journal underwent a remarkably rapid transition to its present focus on evolution and ecology. The profound shifts in the journal's contents over this time are a reflection of the historical changes in science as a whole: from amateur naturalists, to polymath professionals, to increasingly specialized academics. This chronicle reveals the ways in which the <i>American Naturalist</i> has left its mark on many disciplines, many of which are today only loosely affiliated with the journal, if at all.</span></span></span></span></span></span></span></span></span></span></span></p>

Exploiting Phase Transitions in Polymer Bilayer Actuators
<p>In many biological systems, the process of motion involves mechanically morphing materials, which change their mechanical properties and/or shape in response to a control signal. In the past two decades, significant progress has been made toward mimicking the underlying designs and resulting functions in artificial materials and systems. Polymer‐based bilayer bending actuators, in which the dissimilar thermal expansion of two materials is exploited, represent widely investigated actuation elements, but one limitation of this design approach is that the thermal expansion coefficient of polymers is generally small. Herein, it is shown that this problem is mitigated using a thermoplastic polyurethane elastomer with a crystallizable soft segment. The domains formed by the latter reversibly melt and crystallize in a convenient temperature range (30–60 °C), whereas the hydrogen‐bonded urethane hard segments serve as physical crosslinks that provide mechanical integrity and elastic behavior beyond this temperature. Melting the polyester results in a large nonlinear thermal expansion and thus actuation, in a narrow temperature range. The electrically controlled bilayer actuators are created by combining this material with cellulose acetate and integrating resistive heating electrodes. Optionally these devices are equipped with a thermally controlled supramolecular polymer adhesive “gripper.”</p>
