We show that a compact complex surface which bers smoothly over a curve of genus 2 with bers of genus 2 bers holomorphically. We deduce an improvement of a result in [16], and a characterisation of bered surfaces with zero signature. AMS Classi cation 14H15; 14J29, 20F34, 32L30, 57M50

DOI: 10.1002/admi.201500080 concerns pine cones, where asymmetrically positioned differently aligned layers of the nanoand mesoscale cellulose fi brils induce asymmetric water swelling, leading to bending. [ 15 ] In this way, the structure can be considered to be a biological counterpart to so-called bilayer actuators, which are extensively used in technology and science, involving different ex...

The optical properties of several types of polystyrene WLS bers are compared. Fibers having diierent dopant and UV absorber concentrations, and with diierent claddings have been measured. Experimental results on the light yield, light transmission, and mechanical stress tolerance of these bers are presented. A comparative study of those properties is done for Kuraray, Bicron and Pol.Hi.Tech bers.

the cholinergic and gabaergic .bers of the medial septal/diagonal band of broca (ms/db) area project to the hippocampus and constitute the septo-hippocampal pathway, which has been proven to play a role in learning and memory. in addition, the hippocampus has bidirectional connections with the septum so that to self-regulate of cholinergic input. the activity of septal and hippocampal neurons i...
