Peter Bruegel is now famous as the creator of modern landscape painting, but during his lifetime he owed much of his reputation to the satire found in many of his paintings and most of his prints. From an account of the Low Countries by Guicciardini (Antwerp, 1567) we know that in his own day Bruegel was considered a "great imitator of the knowledge and fantasies of Jerome Bosch." Today his sat...

We explore a reaction-dispersal mechanism for the generation of wave fronts which consists of a set of particles traveling with random velocities (chosen from arbitrary distributions) which experience an autocatalytic reaction. The differences found between this mechanism and approaches based on the continuous-time random walks, where the particles are assumed to perform discrete jumps from one...

Closed-form expressions explicitly relating modulation bandwidth and active length in electro-optic traveling wave modulators are presented which fully account for skin-effect electrode loss and optical-electrical wave velocities mismatch. Four operative margins have been identified where the bandwidth-length trade-off figure of merit takes simple forms.

The hypothesis is tested whether the P1 of the event-related potential (ERP) component behaves like an evoked, traveling alpha wave. This hypothesis is based on different kinds of evidence showing, e.g., that-after undergoing phase reorganization-frequencies in the broad alpha range become synchronized (aligned) in absolute phase and contribute significantly to the generation of the P1. We inve...

A festival or gala is an event that is ordinarily staged by a local community that centers around and celebrates a unique aspect of that community. Among many religions, a feast is a set of celebrations in honor of God.1 Each population and community has specific rejoicings and feasts.The joy and jubilation in these solemnities alleviate psychology stress and, hence, one’s health. Nevertheless,...

With the wide adoption of e-commerce in travel and tourism industry, the Internet has become an important travel service delivery channel, and traditional travel agency has been under severe disintermediation threat. This paper reports on a survey conducted to explore the Chinese consumer’s current usage of the Internet as the channel to search travel information and to book travel services. It...

BACKGROUND In travel health risk assessments visiting friends and relatives (VFR) travel status is often used as an indicator for high-risk travel behavior. VFR travelers have been associated with increased risk of travel-associated illnesses due to poor adherence to travel guidelines and lack of pre-travel health consultations. For travelers to dengue endemic regions, guidelines include compli...
