Arrays of nanoscale apertures have been found to exhibit fascinating quantum phenomena such as the Josephson effect and collective quantized phase-slippage. To be in the Josephson regime, the aperture size must be comparable to the healing length of the He order parameter. For 50nm apertures this regime is attained ∼mK below Tλ. Collective phase slippage occurs at considerably lower temperature...

This paper presents experimental investigations carried out on various composite floor deck panel systems. The effects of parameters such as concrete shear length, steel thickness, and thickness the flexural behavior panels were examined. Shear tests identical specimens with four different span lengths. Four-point single-span double-span specimens. stress-slip, load-deformation, moment-curvatur...

In the title compound, C11H9NO2Se, the pyridine and phenyl rings are almost perpendicular, with the dihedral angle between their mean planes being 79.16 (7)°. In the crystal, the mol-ecules pack so as to form ruffled sheets in the (110) plane connected by weak C-H⋯O inter-actions. In addition, there are weak π-π inter-actions between the mean planes of both the phenyl [centroid-centroid perpend...

We present a deep convolutional neural network which is capable to distinguish between different contact states in robotic manipulation tasks. By integrating spatial and temporal tactile sensor data from a piezo-resistive sensor array through deep learning techniques, the network is not only able to classify the contact state into stable versus slipping, but also to distinguish between rotation...

Presence of the dihydrouridine (D) stem in the mitochondrial cysteine tRNA is unusually variable among lepidosaurian reptiles. Phylogenetic and comparative analyses of cysteine tRNA gene sequences identify eight parallel losses of the D-stem, resulting in D-arm replacement loops. Sampling within the monophyletic Acrodonta provides no evidence for reversal. Slipped-strand mispairing of noncontig...

Results from the experimental testing of a navigation system for planetary rovers called Terrain Adaptive Navigation (TANav) are shown here. This system was designed to enable greater access to and more robust operations in terrains with widely varying slippage. The system achieves this goal by using onboard stereo cameras to remotely classify terrain, predict the slippage of that terrain, and ...

In the title compound, C(19)H(13)BrO(3)S, the 4-bromo-phenyl ring makes a dihedral angle of 64.11 (2)° with the mean plane [r.m.s. deviation = 0.01 (2) Å] of the naphtho-furan ring. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits slipped π-π inter-actions between the central naphtho-furan benzene rings of neighbouring mol-ecules [...

Traditional interfacial toughness measurements for thin films on substrate are not appropriate to the structure composed of stiff films and soft substrate. This paper describes a new bending test system to measure the interfacial toughness for the soft interface between stiff films and elastomeric substrate. The experimental setup including the loading stages is easy to operate and scanning ele...
