Video-on-Demand (VoD) services are having more and more impact on people’s daily life. The huge number of view records generated during the services reveal lots of information about video popularity and user behavior. In this work, we seek to understand user behavior from a network approach. Users who overlapped view records are defined as “familiar strangers” of each other. With network scienc...

The purpose of the study was investigate the scale and consequences of the engagement of children in agricultural work activities in Poland. The study covered 1,006 children aged 12-14, who completed an audience questionnaire form: 'Engagement of children in household and farm activities'. As many as 258 children kept diaries, in which they registered all work and everyday activities performed ...

Using Atomic Force Microscopes (AFM) to manipulate nanoobjects is an actual challenge for surface scientists. Basic haptic interfaces between the AFM and experimentalists have already been implemented. The multi-sensory renderings (seeing, hearing and feeling) studied from a cognitive point of view increase the efficiency of the actual interfaces. To allow the experimentalist to feel and touch ...

The chaotic characteristics and maximum predictable time scale of the observation series of hourly water consumption in Hangzhou were investigated using the advanced algorithm presented here is based on the conventional Wolf's algorithm for the largest Lyapunov exponent. For comparison, the largest Lyapunov exponents of water consumption series with one-hour and 24-hour intervals were calculate...

1. Evidence has been found that Northrop's phenomenon (so called by us) is produced in the digestion of casein or hemoglobin brought about by trypsin, papain, and pepsin either crude or crystalline in the presence of gelatin. 2. Anson's and Kunitz' methods permit the measure of proteolytic activity of any protease on casein or hemoglobin substrate in the presence of gelatin, even in very small ...

We report on parallel observations in two seemingly unrelated areas of dynamical network research. The one is the so-called small world phenomenon and/or the observation of scale freeness in certain types of large (empirical) networks and their theoretical analysis. The other is a discrete cellular network approach to quantum space-time physics on the Planck scale we developed in the recent pas...

this study aims to introduce the information seeking anxiety construct as a phenomenon among postgraduate students. it also presents the information seeking anxiety scale (isas) as a valid and reliable instrument. further, the current study investigates the prevalence of information seeking anxiety among postgraduate students at a research-intensive university in kuala lumpur, malaysia. results...

Figure 1. Ischemic ulceration and necrosis of left middle finger. DESCRIPTION A 35-year-old man presented with a 3-year history of episodic fingertip pain with associated discoloration triggered by cold exposure. His job required activities in a subzero walk-in freezer, which exacerbated pain and discoloration. The middle fingertip wound began spontaneously 3 months prior and worsened despite m...
