We consider expanding maps of the circle with an almost neutral fixed point c. In this setting the ergodic averages of a smooth observable A satisfy the Central Limit Theorem. If A(c) = 0 we show that the expectation and the variance behave as the square root of the multiplier of c times rapidly oscillating functions of parameters.

Six RNA aptamers that bind to yeast phenylalanine tRNA were identified by in vitro selection from a random-sequence pool. The two most abundantly represented aptamers interact with the tRNA anticodon loop, each through a sequence block with perfect Watson-Crick complementarity to the loop. It was possible to truncate one of these aptamers to a simple hairpin loop that forms a classical 'kissing...

During each fatal encounter, an intercellular junction called the immunological synapse forms between killer and victim, according to researchers from Oxford University (Oxford, UK). Their work suggests new functions for the immunological synapse and supports the hypothesis that the imm...
متن کاملLove is more than just a kiss: a neurobiological perspective on love and affection.
Love, attachment, and truth of human monogamy have become important research themes in neuroscience. After the introduction of functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET), neuroscientists have demonstrated increased interest in the neurobiology and neurochemistry of emotions, including love and affection. Neurobiologists have studied pair-bonding mechanis...
