An extraction technique is described for vitamin K1 in medical foods, using accelerated solvent extraction (ASE) in conjunction with matrix solid-phase dispersion (MSPD). The medical food sample is treated as it would be with MSPD extraction, followed by ASE for a hands-free automated extraction. The vitamin K1 in the ASE extract is then quantitated by reversed-phase liquid chromatography with ...

A graph G is k-choosable if its vertices can be colored from any lists L(v) of colors with jL(v)j k for all v 2 V (G). A graph G is said to be (k; u)-choosable if its vertices can be colored from any lists L(v) with jL(v)j k, for all v 2 V (G), and with jSv2V (G) L(v)j u. For each 3 k u, we construct a graph G which is (k; u)-choosable but not (k; u+1)-choosable. On the other hand, it is proven...

This paper proposes a method for recognizing handshapes by using multi-viewpoint image sets. The recognition of a handshape is a difficult problem, as appearance of the hand changes largely depending on viewpoint, illumination conditions and individual characteristics. To overcome this problem, we apply the Kernel Orthogonal Mutual Subspace Method (KOMSM) to shift-invariance features obtained f...

A 14 years old girl lost all the fingers of her right hand except the thumb in a Toka (fodder chopping machine) 4 months ago. The fingers had been amputated at the level of the metacarpophalangeal joint. A double toe transfer was done using the second and third toes of her right foot to reconstruct the second and third digits of her right hand using microvascular technique. Bones were fixed wit...

In this work a quantum sorting algorithm with adaptable requirements of memory and circuit depth is introduced, used to develop new version the classical machine learning known as k-nearest neighbors (k-NN). Both efficiency performance k-NN are compared those another proposed by Schuld et al. Results show that both algorithms similar each other superior algorithm. On hand, one k-NN.

Ewing's sarcoma (ES) is a highly malignant neoplasm of childhood and adolescence seen commonly in both axial and appendicular skeleton but uncommonly in acral region. Ewing’s tumor in the hand is extraordinarily rare. Radiological features are variable and can mimic other common lesions. We present a case of 13 year old female, with complaints of pain and swelling in right hand, which on X-ray ...

This paper compares clusters of aligned Persian and English texts obtained from k-means method. Text clustering has many applications in various fields of natural language processing. So far, much English documents clustering research has been accomplished. Now this question arises, are the results of them extendable to other languages? Since the goal of document clustering is grouping of docum...

Let G be a group generated by k elements G = ⟨g1, . . . , gk⟩, with group operations (multiplication, inversion, comparison with id) performed by a black box. We prove that one can test whether the group G is abelian at a cost of O(k) group operations. On the other hand, we show that deterministic approach requires Ω(k) group operations.

In the paper, we continue our study on the state complexity of combined operations on regular languages. We study the state complexities of k ∪ i=1 Li , k ∩ i=1 Li , k ∪ i=1 Li , and k ∩ i=1 Li , for regular languages Li, 1 ≤ i ≤ k. We obtain the exact bounds for these combined operations and show that the state complexities of k ∪ i=1 Li and k ∩ i=1 Li are the same as the mathematical composit...
