Kottayil Madam Ramachandran, Mridhul Ram (2023-11-16)This Ph.D. thesis describes the P-centered as well as other heteroatom-centered reactions of mixed-atom heterocyclic compounds. <br> Initially, the synthesis of the anionic imidazole-2-thione-fused 1,4-dihydro-1,4-diphosphinines ... -
Synthesis, structures and reactivity studies of P-bis(trimethylsilyl)methyl-substituted σ3λ3-oxaphosphirane complexes
Marinas Pérez, Janaina (2011-01-24)This thesis was focused on the investigations of the scope and limitations of the new method of synthesis of oxaphosphirane complexes of the group 6 metal triade based on recently discovered Li/Cl phosphinidenoid complexes. ... -
Synthesizing Human Motions
Krüger, Björn Peter (2012-04-05)In this work different data-driven methods for the synthesis of natural human full body motions are presented. My research in this area was based on the following fundamental questions: Suppose we have all the motion capture ... -
Synthetic evolution of azobenzene and arylazopyrazole photoswitches and translation into photoresponsive DNA nanosystems
Adam, Volker (2019-10-23)Light as an external stimulus provides a powerful and versatile tool to control chemical reactions and biological systems. Light is easily available and permits a high spatial and temporal control while minimizing systemic ... -
System Test and Noise Performance Studies at The ATLAS Pixel Detector
Weingarten, Jens (2007)The central component of the ATLAS Inner Tracker is the pixel detector. It consists of three barrel layers and three disk-layers in the endcaps in both forward directions. The innermost barrel layer is mounted at a distance ... -
Systematic analysis of the synaptic recruitment and activation kinetics of presynaptic inhibitory group II metabotropic glutamate receptors
Rupprecht, Vanessa (2012-08-22)Pharmacological activation of presynaptic inhibitory group II mGluRs potently modulates excitatory synaptic transmission throughout the brain. However, little is known about the physiological conditions under which these ... -
Systematic Computational Analysis of Structure-Activity Relationships
Peltason, Lisa Bertha (2010-04-20)The exploration of structure–activity relationships (SARs) of small bioactive molecules is a central task in medicinal chemistry. Typically, SARs are analyzed on a case-by-case basis for series of closely related molecules. ... -
Systematic Identification of Scaffolds Representing Different Types of Structure-Activity Relationships
Hu, Ye (2011-07-22)In medicinal chemistry, it is of central importance to understand structure-activity relationships (SARs) of small bioactive compounds. Typically, SARs are analyzed on a case-by-case basis for sets of compounds active ... -
Systematic Study of Hadronic Molecules in the Heavy Quark Sector
Cleven, Martin (2014-01-17)In this work we have studied properties of hadronic molecules in the heavy quark sector. These have become increasingly important since from the beginning of this century a large number of states have been measured that ... -
Systematic treatment of Sematophyllaceae (Musci) in Thailand
Pollawatn, Rossarin (2008)<p>The taxonomic treatment of the Sematophyllaceae from Thailand was carried out based on about 2000 specimens. These specimens were on loan from herbaria: University of Aarhus, Denmark (AAU); Royal Forest Herbarium, Bangkok ... -
