OBJECTIVE This study examined dynamic effects of daily variations in craving and negative affect on the next-day risk of the first lapse and relapse among 149 adolescent daily smokers who achieved at least 24 hr of abstinence. METHOD Participants completed real-time assessments of their smoking, craving, and negative affect 3 times per day during the 3 weeks after their quit attempt. The main...

Cells are the building blocks of life, and time lapse microscopy is a powerful way to study cells. Automated video acquisition and analysis of cells opens unprecedented opportunities, ranging from building novel mathematical models supported by rich data to automated drug screening. Unfortunately, accurate and completely automated analysis of cell images is a difficult task. Therefore human int...

Abstract. In July 2018, the International Society for Atmospheric Research using Remotely piloted Aircraft (ISARRA) hosted a flight week to showcase role remotely aircraft systems (RPASs) can have in filling atmospheric data gap. This campaign was called Lower Process Studies at Elevation – Remotely-piloted Team Experiment (LAPSE-RATE). support of this campaign, ground-based remote and situ wer...

For binary black holes the lapse function corresponding to the Brill-Lindquist initial value solution is given in analytic form under the maximal slicing condition. In the limiting case of very small ratio of mass to separation between the black holes the surface defined by the zero value of the lapse function coincides with the minimal surfaces around the singularities. PACS number(s): 04.70.B...

This paper presents a technique to recover geometry from time-lapse sequences of outdoor scenes. We build upon photometric stereo techniques to recover approximate shadowing, shading and normal components allowing us to alter the material and normals of the scene. Previous work in analyzing such images has faced two fundamental difficulties: 1. the illumination in outdoor images consists of tim...

A simple system for the automatic generation of time-lapse animations has been created at the Aerodynamics Laboratory of the Institute for Aerospace Research, National Research Council of Canada (NRC). The system consists of two small Perl programs and a static web page, and relies heavily on two open source software packages: LWP::Simple, and ImageMagick. The first program, tlget.pl, runs for ...
