We consider graphs that admit polyline drawings where all crossings occur at the same angle alpha is an element of (0, pi/2]. We prove that every graph on n vertices that admits such a polyline drawing with at most two bends per edge has O(n) edges. This r ...
In this work, a magnetic measurement system was designed and tested to estimate the Internal-External rotation between the Tibial and Femural parts of a knee prosthesis. To obtain this, the sensors were inserted in polyethylene part while a permanent magne ...
The dynamics of optical switching in semiconductor microcavities in the strong coupling regime is studied by using time-and spatially resolved spectroscopy. The switching is triggered by polarized short pulses which create spin bullets of high polariton de ...
The title compound, C5H10N2S5, was unintentionally obtained as the product of an attempted synthesis of a methyl-carbamodithioic acid using methylamine and carbon disulfide. In the molecule, two dithiocarbamate groups are bridged by a -CH2S- unit. The C-S- ...
The dihedral angle shown by intergranular lead inclusions in Cu-1 wt.% Pb alloys is measured varying the purity of the metal and the temperature. Several measurement methods are used and compared, namely classical two-dimensional (2D) methods based on meta ...
Single-molecule magnets represent the smallest stable magnetic entities available to technology, with promising applications in data storage and quantum computation in sight. Therefore, an interface between devices and single-molecule magnets must be devel ...
Interactions of transmembrane (TM) helices play a key role in many cell processes. The configuration and cross angle these helices adopt are traditionally attributed to specific residue interactions. We present a different approach, in which specific resid ...
This paper explores the dynamics of a highly rotationally and vibrationally excited radical, CD2CD2OH. The radical is produced from the 193 nm photodissociation of 2-bromoethanol-d(4), so it is imparted with high angular momentum and high vibrational energ ...
N-terminal acetylation is a very common post-translational modification, although its role in regulating protein physical properties and function remains poorly understood. α-Synuclein (α-syn), a protein that has been linked to the pathogenesis of Parkinso ...
A new method has been developed to obtain dynamic and structural information about peptide planes in proteins by a combination of measurements of weak short-range cross-correlation rates R(HNN/NC') that are due to concerted fluctuations of the HN-N and N-C ...
