Introduction The Moab Slickrock Trail was the first trail designated primarily for mountain bike use and is one of the most popular mountain bike trails in the world. It was established as a motorcycle trail in 1969, but by the mid 1980s, it was primarily used by mountain bikers. The trail is located on a sandstone plateau overlooking the Colorado River, Moab Valley, and Arches National Park. T...

We show why and how the IĪ valley trajectory commonly used in the literature so far is in fact unsatisfactory. A better IĪ valley is suggested. We also give analytic expressions for the multiple instanton-antiinstanton configurations in the pure Yang-Mills theory. These formulas make it possible to go beyond the dilute gas approximation and calculate the multi-body interactions among instantons...

During May-July 2010 in Namibia, outbreaks of Rift Valley fever were reported to the National Veterinary Service. Analysis of animal specimens confirmed virus circulation on 7 farms. Molecular characterization showed that all outbreaks were caused by a strain of Rift Valley fever virus closely related to virus strains responsible for outbreaks in South Africa during 2009-2010.

Recent disclosures regarding the relationship between Heidegger’s thought and his own version of National Socialism have led me to rethink my earlier efforts to portray Heidegger as a forerunner of deep ecology. His political problems have provided ammunition for critics, such as Murray Bookchin, who regard deep ecology as a reactionary movement. In this essay, I argue that, despite some simila...

After a period of heavy rainfall, an outbreak of Rift Valley fever occurred in southern Mauritania during September-November 2012. A total of 41 human cases were confirmed, including 13 deaths, and 12 Rift Valley fever virus strains were isolated. Moudjeria and Temchecket Departments were the most affected areas.

The valley degree of freedom in the electronic band structure of silicon, graphene, and other materials is often considered to be an obstacle for quantum computing (QC) based on electron spins in quantum dots. Here we show that control over the valley state opens new possibilities for quantum information processing. Combining qubits encoded in the singlet-triplet subspace of spin and valley sta...

Introduction: Fretted terrain and fretted channels are very well developed in the northern part of Arabia Terra [1] and are the site of development of lineated valley fill (LVF) and lobate debris aprons (LDA) [2-3]. The detailed geological history and chronology of this region provide [4] a framework for the interpretation of modification processes operating on and near the dichotomy boundary. ...

Introduction: Mamers Valles is a fretted valley along the dichotomy boundary in the Deuteronilus Men-sae region of Mars (Fig. 1). Analyses of Mamers Valles from Viking images [1-2] characterized it as a fretted channel filled with textured terrain. The channel is interpreted to have formed in the Early Hesperian or earlier [3-4], however, the terrain filling the valley is recent, as young as La...
