As early as the late 1990s, it was recognised that “names are as important in a digital library as an ISBN number is in a traditional library” (Cleveland 1998). In an ideal situation, personal names are as able to identify digital objects uniquely as they are to identify people. In the real world, however, names are sometimes not unique enough to handle identifications for digital objects. This...

I propose to extend the pragmatic syntax of OpenMath by records. Record structures are utilized ubiquitously for representing objects and accessing their components in programming, and we show that this is true for mathematical practice at the informal but rigorous level as well, even though at the formal level records can be reduced to tuples or partial functions. This situation makes records ...

The ideal anti-Zeno effect means that a perpetual observation leads to an immediate disappearance of the unstable system. We present a straightforward way to derive sufficient conditions under which such a situation occurs expressed in terms of the decaying states and spectral properties of the Hamiltonian. They show, in particular, that the gap between Zeno and anti-Zeno effects is in fact ver...

For long-term sea level variability studies a single altimetric mission of high accuracy and long duration is the ideal situation. In reality, several altimetric missions have been flown and the corresponding sea level heights present an increasing accuracy, mainly due to the improved orbital and geophysical corrections applied to the measured data. At least one different preprocessing is used ...

Closure of huge palatal fistula surrounded by fully erupted permanent dentition in the adult patients with cleft is a challenge. Posteriorly based buccinator myomucosal flap is a neurovascular pedicled flap, with inherent nature of thin thickness, saliva secretion, and axial pattern blood supply. Vicinity of donor site to the palate and low donor-site morbidity are the other advantages. It is a...

The potential between heavy quarks can be rigorously defined in a QCD effective field theories framework. I discuss the general situation when the coupling constant may not be considered small and provide an explicit expression for the potential valid up to order 1/m. Spin dependent and spin independent terms are expressed in terms of Wilson loops, completing an ideal journey started twenty yea...

Coding theory plays an important role in efficient transmission of data over noisy communication channels. It consists of two steps; the first step is to encode the data to reduce its sensitivity to noise during transmission, and the second step is to decode the received data by detecting and correcting the noise induced errors. In this thesis an algebraic approach is used to develop efficient ...

In this paper we study a discrete Raman laser amplification model given as a LotkaVolterra system. We show that in an ideal situation, the equations can be written as a Poisson system with boundary conditions using a global change of coordinates. We address the questions of existence and uniqueness of a solution. We construct numerical schemes for the approximation of the solution that have goo...

Cryptographic multilinear maps have many applications, such as multipartite key exchange and software obfuscation. However, the encodings of three current constructions are “noisy” and their multilinearity levels are fixed and bounded in advance. In this paper, we describe a candidate construction of ideal multilinear maps by using ideal lattices, which supports arbitrary multilinearity levels....
