Ultrasonic surface vibration at high frequencies (O(100 GHz)) can nucleate bubbles in a liquid within few nanometres from surface, but the underlying mechanism and role of wettability remain poorly understood. Here, we employ molecular simulations to study characterize this phenomenon, which call acoustothermal nucleation. We observe that nanobubbles on both hydrophilic hydrophobic surfaces, en...

This paper presents a new method for reconstructing piecewise linear surfaces from planar polygonal contours that branch. For non-branching contours, experience has shown that the piecewise linear surface of minimum surface area which connects a pair of contours often provides a good solution. The current algorithm extends this idea by searching for the surface of minimal area which connects tw...

This study was an attempt to explore the reading strategy use of Iranian M.A. students across three different fields of study. Eighty-two M.A. students of power engineering, physics, and communicationwere selected by a Nelson test and the reading comprehension section of a TOEFL. The reading comprehension section of the TOEFL served also as a specific task which helped participants report their...

The study of heat transport in low-dimensional oscillator lattices presents a formidable challenge. Theoretical efforts have been made trying to reveal the underlying mechanism of diversified heat transport behaviors. In lack of a unified rigorous treatment, approximate theories often may embody controversial predictions. It is therefore of ultimate importance that one can rely on numerical sim...
