This article illustrates an unknown page in the fortunes of Giovanni Francesco Commendone’s (1524–84) Discorso sopra la corte di Roma. The analysis starts from first circulation text Roman circles. It then follows work’s journey Rome to library one most important universities Polish–Lithuanian Commonwealth, Akademia Zamojska. Here treatise was read along with a small selection Italian political...

In the traveling salesman path problem, we are given a set of cities, traveling costs between city pairs and fixed source and destination cities. The objective is to find a minimum cost path from the source to destination visiting all cities exactly once. In this paper, we study polyhedral and combinatorial properties of a variant we call the traveling salesman walk problem, in which the object...

Virtual reality (VR) storytelling, particularly in its nonfictional modes, promises a sensory immersion among others whose lives and ways of being privileged viewer might not otherwise experience. In this essay, by focusing on the Emmy-nominated 2018 VR film Traveling While Black, we explore how immersive power storytelling can enact ethnographic encounters premised less impulse to extract mean...

We study the stability of traveling waves of nonlinear Schrödinger equation with nonzero condition at infinity obtained via a constrained variational approach. Two important physical models are Gross-Pitaevskii (GP) equation and cubic-quintic equation. First, under a non-degeneracy condition we prove a sharp instability criterion for 3D traveling waves of (GP), which had been conjectured in the...

The Veterans Health Administration (VHA) provides care to over eight million Veterans and operates over 1,700 sites of care distributed across twenty-one regional networks in the United States. Health care providers within VHA report large seasonal variation in the demand for services, especially in healthcare systems located in the southern U.S. that experience a large influx of "snowbirds" du...

As recently as ninety years ago, traveling simply for the joy of it was an activity charged with implications regarding gender roles. For women in the United States, traveling involved navigating a social landscape as well as a physical one, a situation that many women living in Western democracies would be unfamiliar with today. A lot of the research revolving around the social barriers inhere...

Electromagnetic waves in a system with space and time dependent boundary experience both diffraction Doppler-like frequency conversion. In order to analyse such situations, conventional methods call for either the eigenmodes or dyadic Green's function media. Here, we propose dynamical differential method which does not require of them. Our utilises coordinate transformation simplify calculation...

This study aims to identify the effects of health-related risk perception and sociodemographic characteristics on willingness pay (WTP) for travel insurance as a reduction behavior following outbreak COVID-19. Through application double-bounded dichotomous choice contingent valuation method, this found several determinants price (i.e., toward traveling, about influence COVID-19, past purchase e...
