Trace Elements in Parenteral Nutrition: Considerations for the Prescribing Clinician
Nutrients, 2017 Trace elements (TEs) are an essential component of parenteral nutrition (PN). Over the last few decades, there has been increased experience with PN, and with this knowledge more information about the management of trace elements has become available ...

Involutions, Trace Maps, and Pseudorandom Numbers [PDF]
arXiv, 2016 Interesting properties of the partitions of a finite field $\mathbb F_q$ induced by the combination of involutions and trace maps are studied. The special features of involutions of the form $\frac{u}{z}$, $u$ being a fixed element of $\mathbb F_q$, are exploited to generate pseudorandom numbers, the randomness resting on the uniform distribution of ...

A Python package for fast GPU‐based proton pencil beam dose calculation
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Open‐source GPU‐based Monte Carlo (MC) proton dose calculation algorithms provide high speed and unparalleled accuracy but can be complex to integrate with new applications and remain slower than GPU‐based pencil beam (PB) methods, which sacrifice some physical accuracy for sub‐second plan calculation.

Contaminant trends in US National Estuarine Research Reserves [PDF]
, 2002 Inputs of toxic chemicals provide one of the major types of anthropogenic stress threatening our Nation's coastal and estuarine waters. To assess this threat, the National Oceanic and Atmospheric Administration's (NOAA’s) National Status and Trends (NS&T)

Veech groups without parabolic elements
, 2005 We prove that a ``bouillabaisse'' surface (translation surface which has two transverse parabolic elements) has totally real trace field. As a corollary, non trivial Veech groups which have no parabolic elements do exist.

Selected trace elements concentrations in pregnancy and their possible role - literature review.
Ginekologia Polska, 2017 The aim of this study was to review the role of selected trace elements in pregnancy and fetal development. Citations related to the role of iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) and selenium (Se) during pregnancy were searched in PubMed ...

Energy dependence of the GAFCHROMIC LD‐V1 in the diagnostic radiographic modalities
Journal of Applied Clinical Medical Physics, EarlyView.Abstract The GAFCHROMIC LD‐V1 radiochromic film is widely used in dosimetry because it can provide high‐resolution two‐dimensional dose distributions without processing. This study aimed to evaluate the response characteristics at different effective energies, from the low‐energy range of mammography to the high‐energy range of computed tomography. Net

Scalar multiplication in compressed coordinates in the trace-zero subgroup [PDF]
, 2017 We consider trace-zero subgroups of elliptic curves over a degree three field extension. The elements of these groups can be represented in compressed coordinates, i.e.

Cytotoxic Properties of HT-2 Toxin in Human Chondrocytes: Could T3 Inhibit Toxicity of HT-2?
Toxins, 2019 Thyroid hormone triiodothyronine (T3) plays an important role in coordinated endochondral ossification and hypertrophic differentiation of the growth plate, while aberrant thyroid hormone function appears to be related to skeletal malformations ...
