Adler, Shiota and van Moerbeke obtained for the KP and Toda lattice hierarchies a formula which translates the action of the vertex operator on tau–functions to an action of a vertex operator of pseudo-differential operators on wave functions. This relates the additional symmetries of the KP and Toda lattice hierarchy to the W1+∞–, respectivelyW1+∞×W1+∞– algebra symmeties. In this paper we gene...

this bipartite paper examines the function of tasrif in the quranic story of creation in the light of halliday's textual meta-function. first, the quranic concept of tasrif as a field in elm-al maani (semantics of syntax), and its relation to systemic linguistics is introduced and reviewed. then, through review of literature, it is referred to givenness hierarchy, empathy degree, point of ...

The paper seeks to establish whether Maslowian theory of hierarchy human needs, in concert with other factors, could be a valid explanation for the observed poor insurance buying behaviour most Nigerians. Relying mainly on literature evidence it was that, given poverty level country, an average Nigerian would concerned more his existential needs than bother about security which decision relates...

International law is divided into functionally detached treaty regimes which lack clear hierarchies between them. Specific rules on how to prioritise among conflicting norms, e.g. international patent rights under the World Trade Organisation TRIPS regime and fundamental right health United Nations human law, are missing. Political sentiments economic policies often tend business interests, inc...

the increasing of emigration from villages to cities and decreasing of services to villagers to afford of daily needs causes that they recourse to the cities especial in central business districts. it needs to spend much time and causes to increase the villagers’ costs. so in this article it have been tried to compare between the services centers for villagers in zabol city and it have been tri...

security as one of the basic human needs has a special place in relaxation, comfort and spiritual needs provision. for this reason, security is always of managers, planners, architects and urban designers' interest. solutions and strategies of security provision have been fundamentally changed following prevailing change of housing architecture patterns from homes to residential complexes ...

This study is a needs assessment of ethnic Chinese older adults in Japan. The Delphi method was applied to identify the needs addressed by the focus groups. Maslow’s hierarchy of needs model guided the examination of the community’s political, economic and social environment in satisfying the needs of older community members. The needs were matched with a city’s Health, Welfare, and Long-term C...

We prove the following results: (i) PV proves NP ⊆ P/poly iff PV proves coNP ⊆ NP/O(1). (ii) If PV proves NP ⊆ P/poly then PV proves that the Polynomial Hierarchy collapses to the Boolean Hierarchy. (iii) S2 proves NP ⊆ P/poly iff S 1 2 proves coNP ⊆ NP/O(log n). (iv) If S2 proves NP ⊆ P/poly then S 1 2 proves that the Polynomial Hierarchy collapses to P[log n]. (v) If S2 proves NP ⊆ P/poly the...
