Selective flexibility: Breaking the rigidity of datapath merging

Hardware specialization is often the key to efficiency for programmable embedded systems, but comes at the expense of flexibility. This paper combines flexibility and efficiency in the design and synthesis of domain-specific datapaths. We merge all individual paths from the Data Flow Graphs (DFGs) of the target applications, leading to a minimal set of required resources; this set is organized into a column of physical operators and cloned, thus generating a domain-specific rectangular lattice. A bus-based FPGA-style interconnection network is then generated and dimensioned to meet the needs of the applications. Our results demonstrate that the lattice has good flexibility: DFGs that were not used as part of the datapath creation phase can be mapped onto it with high probability. Compared to an ASIC design of a single DFG, the speed of our domain-specific coarse-grained reconfigurable datapath is degraded by a factor up to 2x, compared to 3-4x for an FPGA; similarly, our lattice is up to 10x larger than an ASIC, compared to 20-40x for an FPGA. We estimate that our array is up to 6x larger than an ASIC accelerator, which is synthesized using datapath merging and has limited or null generality. © 2012 EDAA

Magneto-optical effects in semimetallic Bi1-xSbx (x=0.015)

We report the results of infrared and magneto-optical spectroscopy study on electrodynamic response of bismuth doped with 1.5% of antimony. The spectra are presented for temperatures down to 4.2 K, and in magnetic fields as high as 18 T. The results reveal strong magneto-optical activity, similar to pure bismuth, however there are some differences introduced by antimony doping. Analysis of optical functions reveals that the two type of charge carriers respond differently to external magnetic field. Finally, when the system enters the extreme quantum regime, both the inter- and intraband Landau Level transition are observed in the spectra

Magneto-optical effects in 1-xAsx with x=0.01: Comparison with topo- logical insulator Bi1-xSbx with x=0.20

In this work, we explore possible topological insulating state in bismuth doped with arsenic Bi1-xAsx. Infrared and magneto-optical spectroscopy are employed to probe the electrodynamic response of Bi1-xAsx with x = 0.01, as well as topological insulator Bi1-xSbx with x = 0.20. The spectra are reported in magnetic fields up to 18T, and at temperatures between 10 and 300K. The results indicate strong sensitivity of optical properties to these external stimuli in both Bi1-xAsx and Bi1-xSbx, but also some differences introduced by arsenic doping. Most notably, the field dependence of cyclotron resonance in Bi1-xAsx implies that it is due to bulk carriers, as opposed to surface carriers in Bi1-xSbx

Many Labs 5: Registered Replication of LoBue and DeLoache (2008)

Across three studies, LoBue and DeLoache (2008) provided evidence suggesting that both young children and adults exhibit enhanced visual detection of evolutionarily relevant threat stimuli (as compared with nonthreatening stimuli). A replication of their Experiment 3, conducted by Cramblet Alvarez and Pipitone (2015) as part of the Reproducibility Project: Psychology (RP:P), demonstrated trends similar to those of the original study, but the effect sizes were smaller and not statistically significant. There were, however, some methodological differences (e.g., screen size) and sampling differences (the age of recruited children) between the original study and the RP:P replication study. Additionally, LoBue and DeLoache expressed concern over the choice of stimuli used in the RP:P replication. We sought to explore the possible moderating effects of these factors by conducting two new replications—one using the protocol from the RP:P and the other using a revised protocol. We collected data at four sites, three in Serbia and one in the United States (total N = 553). Overall, participants were not significantly faster at detecting threatening stimuli. Thus, results were not supportive of the hypothesis that visual detection of evolutionarily relevant threat stimuli is enhanced in young children. The effect from the RP:P protocol (d = −0.10, 95% confidence interval = [−1.02, 0.82]) was similar to the effect from the revised protocol (d = −0.09, 95% confidence interval = [−0.33, 0.15]), and the results from both the RP:P and the revised protocols were more similar to those found by Cramblet Alvarez and Pipitone than to those found by LoBue and DeLoache

Does Distance from the Equator Predict Self-Control? Lessons from the Human Penguin Project

We comment on the proposition “that lower temperatures and especially greater seasonal variation in temperature calls for individuals and societies to adopt…a greater degree of self-control”, for which we cannot find empirical support in a large dataset with data-driven analyses. After providing more nuance in our theoretical review, we suggest revisiting their model with an eye to the social determinants of self-control
