we study the theory of best approximation in tensor product and the direct sum of some lattice normed spacesx_{i}. we introduce quasi tensor product space anddiscuss about the relation between tensor product space and thisnew space which we denote it by x boxtimesy. we investigate best approximation in direct sum of lattice normed spaces by elements which are not necessarily downwardor upward a...

in this paper, we prove some results on characterization of $varepsilon$-simultaneous approximations of downward sets in vector lattice banach spaces. also, we give some results about simultaneous approximations of normal sets.

This paper describes an efficient edge-preserved regularization algorithm for downward continuation of magnetic data in detection of unexploded ordnance (UXO). The magnetic anomalies arising from multi-source UXO can overlap at a height over the ground surface, while causative sources may not be readily separated due to low level of signal-to-noise ratio of the observed data. To effectively the...

Early diagnosis and management of strabismus is needed to avoid complications such as amblyopia. In this retrospective cohort study we reviewed the profile and surgical outcome of vertical strabismus patients attending a clinic in Yazd city in the Islamic Republic of Iran. From the medical files of 265 patients, 19.2% were found to have pure vertical deviation and 80.8% had combined horizontal ...

Thirty-one patients presented for surgical correction of unilateral hypotropia of the globe and blepharoptosis. The hypotropia and pseudoptosis were corrected by Knapp procedures. The Bell's phenomenon was thereby improved, allowing safe correction of the true ptosis, generally by an anterior levator resection whose magnitude depended on measured levator function.

The downward closure of a word language is the set of all (not necessarily contiguous) subwords of its members. It is well-known that the downward closure of any language is regular. While the downward closure appears to be a powerful abstraction, algorithms for computing a finite automaton for the downward closure of a given language have been established only for few language classes. This wo...

We present the first polynomial-time algorithm for computing the minimal covering set of a (weak) tournament. The algorithm is based on a linear programming formulation of a subset of the minimal covering set known as the essential set. On the other hand, we show that no efficient algorithm exists for two variants of the minimal covering set, the minimal upward covering set and the minimal down...

We study the implications for optimal monetary policy when declining nominal wages is not a viable margin for adjustment to adverse economic conditions. To this end, we develop a New Keynesian model where downward nominal wage rigidity arises endogenously. We show that the optimal policy response to changing economic conditions is asymmetric. Another important finding is that downward nominal r...
