We prove a family of identities that involve the solution u to the following Cauchy problem: i∂tu +∆u = 0, u(0) = f(x), (t, x) ∈ Rt × R n x , and the Ḣ 1 2 (R)-norm of the initial datum f . As a consequence of these identities we shall deduce a lower bound for the local smoothing estimate proved in [3], [8] and [9] and a uniqueness criterion for the solutions to the Schrödinger equation. This p...

Writing projects are socially-situated identities. The rhetorically-loaded aspects of writing, like metadiscourse marking, are more prone to carry such identities. Through analyzing metadiscourse strategies employment in Persian and English (as the lingua franca of academic discourse community) research articles, this study makes an attempt to find out whether Persian native writers take on the...

We introduce degree n Sabinin algebras, which are defined by the polynomial identities up to degree n in a Sabinin algebra. Degree 4 Sabinin algebras can be characterized by the polynomial identities satisfied by the commutator, associator and two quaternators in the free nonassociative algebra. We consider these operations in a free power associative algebra and show that one of the quaternato...

The youth have long represented an important constituency for electoral mobilization in Africa. Today, as the region faces a growing ‘youth bulge’ that is disproportionately burdened by unand underemployment, capturing the votes of this demographic is becoming more important than ever before. Yet, despite their numerical importance and the historical relevance of generational identities within ...

Many organizations maintain identity information for their customers, vendors, and employees, etc. However, identities being compromised cannot be retrieved effectively. In this paper we first present a case study on identity problems existing in a local police department. The study show that more than half of the sampled suspects have altered identities existing in the police information syste...

In many Latin American countries football has been central to the formation of identities in the twentieth century, whether these be national, ethnic, local, generational, or gender identities. In this light, a comparison between the explanations given for the Brazilian defeat in the 1950 World Cup, which took place in Brazil itself, and that in the 1998 World Cup Final in France can serve as a...

This paper argues that community development has much to learn from the discursive strategies developed within Barack Obama’s successful 2008 presidential campaign. The discourse of the campaign constructed specific identities of both Obama and the public which (re)produced a collective mood for change. By constructing the public (rather than the campaign) as active agents for change, the Obama...

different methods arising from scientific investigation for removing noise from chaotic signals have been introduced and one of their best is local projection approach. the local projection approach projects the chaotic data in the neighborhood onto the hyper-plane. selection of neighborhood radius has a direct impact on its performance. a noticeable feature associated with chaotic trajectories...

Criminals often falsify their identities intentionally in order to deter police investigations. In this paper we focus on uncovering patterns of criminal identity deception observed through a case study performed at a local law enforcement agency. We define criminal identity deception based on an understanding of the various theories of deception. We interview a police detective expert and disc...
