The rank-k numerical range has a close connection to the construction of quantum error correction code for a noisy quantum channel. For noisy quantum channel, a quantum error correcting code of dimension k exists if and only if the associated joint rank-k numerical range is non-empty. In this paper the notion of joint rank-k numerical range is generalized and some statements of [2011, Generaliz...

the present study-both qualitative and quantitative--explored fifty efl learners’ preferences for receiving error feedback on different grammatical units as well as their beliefs about teacher feedback strategies. the study also examined the effect of the students’ level of writing ability on their views about the importance of teacher feedback on different error types. data was gathered throug...

The issue of whether or not to correct errors in students’ writing is controversial. Some scholars argue that error correction is helpful, while others argue that it is ineffective, perhaps even harmful. What is missing from the literature are studies about how error correction might affect the performance of specific types of students. This study, which included 140 undergraduate English major...

It's not surprisingly when entering this site to get the book. One of the popular books now is the the complexity of noise a philosophical outlook on quantum error correction. You may be confused because you can't find the book in the book store around your city. Commonly, the popular book will be sold quickly. And when you have found the store to buy the book, it will be so hurt when you run o...

Chording is a technique that allows users to enter text without visual feedback. Traditional chording strategies are hampered by the substantial training effort required as users need to memorize chords. In this study an alternative chording scheme that uses spatial mnemonics to accelerate learning is proposed. Users mentally visualize the appearance of each character as a 3 × 3 pixel grid. The...

globalization is a worldwide phenomenon. the concept globalization is a very recent term only establishing its current meaning in the 1970s, which emerged from the intersection of four inter related sets of communities of practice, academics, journalists, publishers. this paper models the channels through which globalization affects financial sector development in nigeria. to this end this stud...

We prove a general form of bit flip formula for the quantum Fourier transform on finite abelian groups and use it to encode some general CSS codes on these groups.
