In the paper, we show that there is a complex structure on the elliptic surface E(4) with k sections rationally blown down for 2 ≤ k ≤ 9. And we interpret it via Q-Gorenstein smoothings.

Negacyclic BCH codes are a subclass of neagcyclic and the best linear in many cases. However, there have been very few results on negacyclic codes. Let q be an odd prime power m positive integer. The objective this paper is to study with length $$\frac{q^m-1}{2}$$ $$\frac{q^m+1}{2}$$ over finite field $${\textrm{GF}}(q)$$ analyse their parameters. presented good parameters general, contain opti...

Simulating a crowded scene like a busy shopping street requires tight packing of virtual characters. In such cases collisions are likely to occur, and the choice in collision detection shape will influence how characters are allowed to intermingle. Full collision detection is too expensive for crowds, so simplifications are needed. The most common simplification, the fixed-width, pose-independe...

OBJECTIVES To assess community perceptions of mental illness in the Bwindi Community Hospital (BCH) catchment area: to recognise beliefs about the causes and the treatments for mental illness. To provide community data to staff at BCH as they work to develop more effective community mental health programmes. BACKGROUND A shortage of mental health providers in Uganda has prompted research into...
