Open AccessMeasurements of ultrafast spin-profiles and spin-diffusion properties in the domain wall area at a metal/ferromagnetic film interface
Exciting a ferromagnetic material with an ultrashort IR laser pulse is known to induce spin dynamics by heating the spin system and by ultrafast spin diffusion processes. Here, we report on measurements of spi...

Open AccessModel-independent particle species disentanglement by X-ray cross-correlation scattering
Mixtures of different particle species are often investigated using the angular averages of the scattered X-ray intensity. The number of species is deduced by singular value decomposition methods. The full dis...

Prevention and treatment of bile duct injuries during laparoscopic cholecystectomy: the clinical practice guidelines of the European Association for Endoscopic Surgery (EAES)
Laparoscopic cholecystectomy is one of the most common surgical procedures in Europe (and the world) and has become the standard procedure for the management of symptomatic cholelithiasis or acute cholecystiti...

Open AccessUltrafast optical demagnetization manipulates nanoscale spin structure in domain walls
During ultrafast demagnetization of a magnetically ordered solid, angular momentum has to be transferred between the spins, electrons, and phonons in the system on femto- and picosecond timescales. Although th...

Fast Track—Different Implications in Pancreatic Surgery
Concepts in “fast-track” surgery, which provide optimal perioperative care, have been proven to significantly reduce complication rates and decrease hospital stay. This study explores whether fast-track concep...

Anharmonic motions of Kr in the clathrate hydrate
The anomalous glass-like thermal conductivity of crystalline clathrates has been suggested to be the result of the scattering of thermal phonons of the framework by ‘rattling’ motions of the guests in the clat...

Phase behaviour of n-hexane/perfluoro-n-hexane binary thin wetting films
We present X-ray reflectivity investigations of the concentration distribution in binary liquid thin films on silicon substrates. The liquid-vapor coexistence of the binary mixture investigated, hexane and per...

Rotational dynamics in methane hydrate
We performed neutron spectroscopy and neutron-diffraction experiments on both natural and laboratory-made methane hydrates. The experiments focussed on the rotational dynamics and the orientational scattering ...

Oncologic implications of laparoscopic and open surgery
Although instrumental manipulation and mechanical tumor cell spillage seem to play the major role in port-site metastases from laparoscopic cancer surgery, minimally invasive procedures are used more and more ...

Laparoscopic cecal ligation and puncture in the rat
Background: We describe a technique of laparoscopic cecal ligation and puncture (CLP) in the rat analogous to open CLP which may facilitate the study of minimally invasive surgery (MIS) and perit...
