background: routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. we figure that repeat testing of critical laboratory values has any benefits or not.   methods : we examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white b...

a new base isolation method for reducing the destructive effect of earthquake is proposed in this method mushroom shaped basements are used under structures as base isolation. these basements have spherical surface and are located on foundations. basements have pinned arms that are connected. when the length of the arm is less then the radius of spherical surface, the action of them is similar ...

This paper investigates the in-hand manipulation capabilities of a compliant, underactuated planar robotic hand by treating the system as a simple, symmetric, 6-bar linkage mechanism with compliant joints. Although underactuated hands are generally not considered to be adept at dexterous tasks, we have found through past work that an underactuated manipulator can control n degrees of freedom wi...

The relationship between the %V, ΔC, and ΔV metrics of rhythm and the phonological characteristics they are generally believed to relate to is directly investigated. A cross-linguistically diverse sample of languages is examined to determine whether languages which pattern similarly according to phonological features, including range of allowable syllable structure, presence of phonemic vowel l...

A priority queue, a container data structure equipped with the operations insert and delete-minimum, can re-order its input in various ways, depending both on the input and on the sequence of operations used. If a given input σ can produce a particular output τ then (σ, τ) is said to be an allowable pair. It is shown that allowable pairs on a fixed multiset are in one-to-one correspondence with...

There are only two viable low-energy E6 subgroups: SU(3)C ×SU(2)L ×U(1)Y × U(1)N or SU(3)C × SU(2)L × SU(2)′R × U(1)YL+Y ′ R , which would not erase any preexisting lepton asymmetry of the Universe that may have been created by the decay of heavy singlet (right-handed) neutrinos or any other mechanism. They are also the two most favored E6 subgroups from a recent analysis of present neutral-cur...
