Electromagnetic waves which propagate along a Josephson junction ladder are shown to manifest themselves by resonant steps in the current-voltage characteristics. We report on experimental observation of resonances in ladders of different geometries. The step voltages are mapped on the wave dispersion relation which we derive analytically for the general case of a ladder of arbitrary anisotropy...

Almost all proteins contain charged amino acids. While the function in catalysis or binding of individual charges in the active site can often be identified, it is less clear how to assign function to charges beyond this region. Are they necessary for solubility? For reasons other than solubility? Can manipulating these charges change the properties of proteins? A combination of capillary elect...

The history of genus distributions began with J. Gross et al. in 1980s. Since then, a lot of study has given to this parameter, and the explicit formulas are obtained for various kinds of graphs. In this paper, we find a new usage of Chebyshev polynomials in the study of genus distribution, using the overlap matrix, we obtain homogeneous recurrence relation for rank distribution polynomial, whi...

Pursuing a series of progressive (e.g., professional) goals that form a goal ladder often leads to a trade-off between moving up to a more advanced level and repeating the same goal level. This article investigates how monitoring one's current goal in terms of remaining actions versus completed actions influences the desire to move up the goal ladder. The authors propose that a focus on remaini...

This paper presents e-Snakes and Ladders (e-S&L), a game-based educational environment for portable devices. The e-S&L is based on the classic table game “Snakes and Ladders” and enriches the table game with various types of activities like Questions&Answers and Web-Quests. It provides a pleasant e-learning environment with an easy to use authoring tool for the instructor. The e-S&L is based on...

Chiral nanoscale photonic systems typically follow either tetrahedral or helical geometries that require four or more different constituent nanoparticles. Smaller number of particles and different chiral geometries taking advantage of the self-organization capabilities of nanomaterials will advance understanding of chiral plasmonic effects, facilitate development of their theory, and stimulate ...

The warp is a device that reframes notions of time and space. It is a common cultural artefact, one that audiences have come to recognise and believe in through various media. We accept the bed in Bedknobs and Broomsticks, the Tardis in Doctor Who, the supralight speed engines of science fiction, as time/space travel devices in order to get characters from A to B, to advance their progress alon...

We explicitly describe the divisor class groups and semidualizing modules for ladder determinantal rings with coefficients in an arbitrary normal domain ladders, not necessarily connected, all sizes of minors.

conclusions perceptions of nursing were significantly different from those of the ideal career in most of the attributes. therefore, it is recommended that nurses’ income, workplace safety, and sense of being appreciated and respected by all authorities should be improved. background identification of the attributes of nursing and the ideal career, and their similarities and differences, as per...

A cross-sectional study of a cohort of 197 clinical dental students in the four accredited dental schools in Nigeria was conducted to determine the sociodemographic characteristics of these dental students and their motives for the choice of dentistry. The results indicate that the number of female dental students in Nigeria is increasing, which reflects a trend well established in virtually al...
