In a bivariate data plot, every two points determine an “elementary slope.” For n points with distinct x-values, there are n(n – 1)/2 elementary slopes. These elementary slopes are examined under the two classical regression assumptions: (1) the regressor variable values are fixed and the error is independent and normal, and (2) the data is bivariate normal. For case (1), it is demonstrated tha...

The elementary theory of Lie1 groups has something in common with precalculus: One wants to get past it in order to get on with the beautiful and powerful theory that follows, as well as the applications. With precalculus the theory that follows is built around calculus and its fundamental theorem, extending into calculus of several variables and having profound applications through the subject...

A room temperature hybrid electrolyte based lithium-sulfur cell was successfully cycled with an excellent coulombic efficiency of 100%. The initial discharge specific capacities of up to 1528 mA h g(-1), 1386 mA h g(-1) and 1341 mA h g(-1), respectively, at C/20, C/5 and C/2 rates were realized and remained at 720 mA h g(-1) after 40 cycles at the C/5 rate.

with no adverse effects reported. One patient treated herself with albendazole (400 mg/day for 3 days) before she was seen at a hospital. All patients became asymptomatic and had negative stool examination results 2–10 weeks after treatment. None of the patients reported previous or subsequent consumption of raw freshwater fi sh. Raw fi sh preparations such as sushi, sashimi, carpaccio, and cev...

The byte block cipher Two sh was proposed as a candidate for the Advanced En cryption Standard AES This paper notes the following two properties of the Two sh key schedule Firstly there is a non uniform distribution of byte whitening subkeys Sec ondly in a reduced xed Feistel round function Two sh with an byte key there is a non uniform distribution of any byte round subkey An example of two di...

BACKGROUND Subclinical hypothyroidism (SH) is associated with adverse obstetric outcomes and neurodevelopment disorders. Both iodine deficiency and excess are associated with SH; however, few data regarding iodine nutrition status of pregnant women with SH are available. This study aimed to clarify whether iodine deficiency or excess is associated with SH, especially, when test results for anti...

Copper concentrations were measured in a 65 samples marketed and collected in Croatia in summer 2012: meat samples (bovine, pig, sheep), meat products (sausages, pâté), fi sh and fi sh products and shellfi sh (mussels, oysters). Mean Cu levels were (mg/kg): all meat 0.77, sausages 0.69, pâté 2.24, fi sh 0.23, fi sh products 1.20, mussels 0.81, oysters 30.0. Signifi cant diff erences were found ...
