The hairy attachment system of spiders enables these animals to walkupside-down on rough and smooth surfaces without the use of glue.These outstanding biological structures comprise of pads includinghundreds to thousands of specially designed hairs that are made ofcomposite materials consisting of proteins and reinforcing chitin fibres.The goal of our study is to gain an in-depth understanding of thestructure-function mechanism of the attachment and detachment processesof single hairs to a surface. X-ray Tomographic Microscopy andScanning X-ray nanobeam diffraction are ideal tools to reveal the innerstructure of the spider hairs and allow to determine the gradient of themechanical properties which is essential for the attachment process.With both techniques we found that the shaft of the attachment hairis hollow.

Many supersymmetric models feature gauginos and also sleptons withmasses less than a few hundred GeV. These can give rise to direct pairproduction rates at the LHC that can be observed in the data samplerecorded by the ATLAS detector [...]

QCD evolution equations can be recast in terms of parton branching processes. We present a newnumerical solution of the equations and show, that this method reproduces the semi-analytical solutions.We discuss numerical effects of the kinematic boundary of resolvable branchings on the resultingparton distribution functions. [...]

This talk will describe searches for Higgs bosons decaying into two b-quarks at the ATLAS and CMSexperiments, presenting the analysis methods and results. Emphasis will also be put on the QCDaspects that are relevant for the analyses..

We present measurements of multi-differential Jet cross sections over a wide range in transversemomenta from inclusive jets to multi-jet final states. We present studies on the impact these measurementshave on the determination of the strong coupling alphas as well as on parton densityfunctions. [...]

The talk reviews the measurements of the 125 GeV Higgs boson in several final states, performedby the CMS collaboration. The main focus is on results obtained with data from LHC proton-protoncollisions at a centre-of-mass energy of 13 TeV..

Recent results on diffraction from the H1 and ZEUS experiments at HERA are presented. Measurement of open charm production in diffractive DIS has been performed by the H1 experiment using the event topology, given by ep→eXY, where the system X, containing at least one D*(2010) meson, is separated from a leading low-mass proton dissociative system Y by a large rapidity gap. [...]

The CALICE Collaboration is developing highly granular calorimeters for a future e+e− linear collider. The development of the calorimeters is driven by the Particle Flow approach (PFA) in order to achieve a jet energy resolution of 3-4 %. [...]

In-situ investigations of the crystallization of solids are still necessary for the understanding and the rational synthesis of precursors, intermediates and products with special or even improved properties.[1] With our crystallization cell,[2] the detection and the control of different reaction parameters during chemical reactions in fluid media can be achieved. The modifications of the cell allow in-situ experiments with X-ray diffraction (XRD).[2] The crystallization of Al(acac)3 (acac = acetylacetonate) as model system was investigated to demonstrate the performance of the cell. [...]

We report recent progress made in a synchronous multi-color mode-locked laser network over 4.7-km distance. Output of two remotely synchronized lasers shows only 0.6-fs RMS drift over 40 hours reaching 20th decimal uncertainty in less than 10000-s averaging time. [...]
