According to [1] Sect 8.1.1, the encryption key CK ESP shall be obtained from the key CK IM established as a result of the AKA procedure, using a suitable key expansion function, the latter to be specified in Annex I. Below, we study two alternatives for key expansion functions meeting the above length requirements and their security properties. We first note that the key CK IM is 128 bits in l...

Aggregations of young animals are common in a range of endothermic and ectothermic species, yet the adaptive behavior may depend on social circumstance and local conditions. In penguins, many species form aggregations (aka. crèches) for a variety of purposes, whilst others have never been observed exhibiting this behavior. Those that do form aggregations do so for three known benefits: 1) reduc...

Geometry optimization and vibrational spectra (infrared and Raman spectra) calculations of proteins are carried out by a quantum chemical approach using the EE-GMFCC (electrostatically embedded generalized molecular fractionation with conjugate caps) method (J. Phys. Chem. A, 2013, 117, 7149). The first and second derivatives of the EE-GMFCC energy are derived and employed in geometry optimizat...

Just because you pitch a tent doesn't mean you're ready to go camping. In other words, yes ? men can have erections without feeling sexually excited or horny. These erections, aka spontaneous erections, are perfectly normal and common, popping up when guys are eating dinner, are called on in class, riding a bike, watching a movie, reading, sleeping, talking with grandma, or doing just about any...

A comparison is made between the frequency of local minima in the analytic power (AP) of intracranial EEG (ECoG) from waking and unconscious human subjects and the frequency of putative frames of consciousness reported in earlier psychological literature. In ECoG from unconscious subjects, the frequency of deep minima in AP is found to be a linear function of bandwidth. In contrast, in ECoG fro...

The Australian species of the genus Aka White are revised. Seven new species are described: A. balma sp. nov., A. dobsonensis sp. nov., A. gwana sp. nov., A. issidopsis sp. nov., A. kuraka sp. nov., A. pirri sp. nov., A. sorellensis sp. nov. Adding to those the 5 species solely occurring in New Zealand, we have a total number of 14 species in Aka. The types of A. hardyi Muir, 1931 and part of t...

Background: Paper mulberry is one of the most common skin-lightening agents in beauty industry due to its strong anti-tyrosinase activity.
