Variable selection is a key step for eliminating redundant information in spectroscopy. Among various variable selection methods, the physarum network (PN) is a newly-introduced and efficient one. However, the whole spectrum has to be equally divided into sub-spectral bands in PN. These division criteria limit the selecting ability and prediction performance. In this paper, we transform the spe...

We give an upper bound in O(d) for the number of critical points of a normal random polynomial. The number of minima (resp. maxima) is in O(d)Pn, where Pn is the (unknown) measure of the set of symmetric positive matrices in the Gaussian Orthogonal Ensemble GOE(n). Finally, we give a closed form expression for the number of maxima (resp. minima) of a random univariate polynomial, in terms of hy...

Parenteral nutrition (PN) provision is complex, as it is a high-alert medication and prone to a variety of potential errors. With changes in clinical practice models and recent federal rulings, the number of PN prescribers may be increasing. Safe prescribing of this therapy requires that competency for prescribers from all disciplines be demonstrated using a standardized process. A standardized...

Suppose Pn = {1, 2, . . . , n} is a partially ordered set with the partial order defined by divisibility, that is, for any two distinct elements i, j ∈ Pn satisfying i divides j, i <Pn j. A table An = {ai|i = 1, 2, . . . , n} of distinct real numbers is said to be consistent with Pn, provided for any two distinct elements i, j ∈ {1, 2, . . . , n} satisfying i divides j, ai < aj . Given an real ...

Premature very low birth weight (< 1500 g) infants comprise one of the largest groups receiving parenteral nutrition. PN should be optimized to answer their high nutritional requirements and suit their metabolic status, but should also be validated pharmaceutically. PN can be provided as a standard, usually commercial, formulation, representing the average needs of a large group of patients. Al...

this is a case presentation of a 26-year-old woman with a moderate-sized atrial septal secundum defect (17mm) who underwent catheterism, during which an amplatzer septal occluder number 26 was inserted successfully. on the second postoperative day, she deteriorated and a clinical examination showed a typical tamponade. after a percutaneous aspiration of the pericardial cavity and transient impr...

background: cobalamin deficiency and peripheral neuropathy (pn) are commonly seen in hiv-infected adults. the level of urine methylmalonic acid (umma), a reliable indicator of tissue cobalamin status, was determined in hiv infected subjects with and without pn to establish this association. methods: one hundred and ninety-eight (198) consenting hiv infected subjects with and without pn were rec...

We prove that the probability PN for a real random Gaussian N ×N ×2 tensor to be of real rank N is PN = (Γ((N + 1)/2))N/G(N + 1), where Γ(x), G(x) denote the gamma and Barnes G-functions respectively. This is a rational number for N odd and a rational number multiplied by πN/2 for N even. The probability to be of rank N + 1 is 1− PN . The proof makes use of recent results on the probability of ...

INTRODUCTION Parenteral nutrition (PN) is an integral part of medical management of patients who do not have a functioning or accessible gastrointestinal tract. This paper discusses the clinical characteristics of patients receiving PN in a 420-bed hospital from 2009 to 2011. In addition, nutritional parameters were assessed at the start and end of PN and associated complications were analyzed....
