Fusion of bilayer membranes is studied via dissipative particle dynamics (DPD) simulations. A new set of DPD parameters is introduced which leads to an energy barrier for flips of lipid molecules between adhering membranes. A large number of fusion events is monitored for a vesicle in contact with a planar membrane. Several time scales of the fusion process are found to depend exponentially on ...

This work presents a dataset and annotation scheme for the new task of identifying “good” conversations that occur online, which we call ERICs: Engaging, Respectful, and/or Informative Conversations. We develop a taxonomy to reflect features of entire threads and individual comments which we believe contribute to identifying ERICs; code a novel dataset of Yahoo News comment threads (2.4k thread...

The main result of the papzer is that any planar graph with odd girth at least 10k À 7 has a homomorphism to the Kneser graph G 2k‡1 k , i.e. each vertex can be colored with k colors from the set f1; 2;. .. ; 2k ‡ 1g so that adjacent vertices have no colors in common. Thus, for example, if the odd girth of a planar graph is at least 13, then the graph has a homomorphism to G 5 2 , also known as...

An ultra low-power digital signal processor (DSP) is proposed for the digital hearing aid. The DSP has a SNR monitor to vary its internal clock frequency in accordance with the input signal level. Digital filters use hardwired barrel shifters in place of multipliers, and a parameter ROM provides filter parameters. The clock generator consumes only 1 μW at sub-1V. The DSP consumes only 10 μW at ...

Using scanning tunneling spectroscopy, we investigated the temperature dependence of the quasiparticle density of states of overdoped Bi2Sr2CuO6+δ between 275 mK and 82 K. Below Tc=10K, the spectra show a gap with well-defined coherence peaks at ±Δp≃12meV, which disappear at Tc. Above Tc, the spectra display a clear pseudogap of the same magnitude, gradually filling up and vanishing at T∗≃68K. ...

At low redshifts, measurements of the total baryon content in stars, atomic and molecular hydrogen, and cluster gas fall a factor of two to four below the baryon density derived from observed light-element ratios and nucleosynthesis arguments. A possible hiding place for a significant fraction of the missing baryons is in the warm/hot gas at temperatures T= 10 − 10K. We present predictions of t...

This paper describes a series of experiments that were performed on the Rocky III rob0t.l Rocky III is a small autonomous rover capable of navigating through rough outdoor terrain to a predesignated area, searching that area for soft soil, acquiring a soil sample, and depositing the sample in a container at its home base. The robot is programmed according to a reactive behaviorcontrol paradigm ...

1. Implement AdaBoost with boosting stumps and apply the algorithm to the spambase data set of HW2 with the same training and test sets. Plot the average cross-validation error plus or minus one standard deviation as a function of the number of rounds of boosting T by selecting the value of this parameter out of {10, 102, . . . , 10k} for a suitable value of k, as in HW2. Let T ∗ be the best va...

Autism spectrum disorders (ASDs) are common, heritable neurodevelopmental conditions. The genetic architecture of ASDs is complex, requiring large samples to overcome heterogeneity. Here we broaden coverage and sample size relative to other studies of ASDs by using Affymetrix 10K SNP arrays and 1,168 families with at least two affected individuals, performing the largest linkage scan to date wh...

| We propose an FPGA architecture for next generation B-ISDN telecommunications systems. Such a system requires an FPGA in which an over 10K gates circuit can be implemented and that has a clock cycle rate of 80MHz. While the FPGA architecture has been discussed in terms of its circuit structure, we consider the circuit structure of the FPGA with its CAD tools. We evaluate several FPGA logic-el...
