Analytical Development of A Plastic Hinge Detail for Steel SMFs
… for use in steel special moment frames (SMFs). The aim of the special detail design is to dissipate seismic energy through stable yielding of a beam "link" in plastic hinge region. Reliable and repeatable energy dissipation at high ductility is assured through the elimination of weld …

Influence of the Gravity System on the Seismic Performance of Special Steel Moment Frames
… performance of Special Steel Moment Frames (SMFs). The influence was quantified using the FEMA P-695 methodology. The buildings used for this study were a 2-, 4- and 8-story SMFs taken from the ATC76-1 project where their collapse performance was already evaluated without the gravity system. …

Multi-domain Protein Unfolding Pathway Studies by Single Molecule Techniques
… signal from single molecule force spectroscopy (SMFS) based on atomic force microscopy (AFM) can be directly identified. Beyond this published work, I also characterized and compared the unfolding pathway of two homologous multi-domain proteins – yeast phosphoglycerate kinase (PGK) and its E.coli …

Mechanical unfolding of membrane proteins captured with single-molecule AFM techniques
… so called single molecule force spectroscopy (SMFS), allows for investigation of the strength of molecular interactions of different origins established between and within biological molecules. In the present work, SMFS was used to detect and locate structurally and functionally important …

Advances in single molecule spectroscopy and microscopy for biological imaging and polymer characterization
… we use single molecule force spectroscopy (SMFS) to study the mechanical properties of polymer systems. Here, we specifically examine the effect of the photostabilizer Trolox on the physical properties of the biopolymer, DNA. Using this technique, we exert force on a single polymer and …

Synthesis and single-molecule force spectroscopy of supramolecular capsules
… et al. in 2003 was the basis for successful SMFS experiments. In the force spectroscopy experiments using diluted SAMs, specific single-molecule dissociation events which could be assigned to the dissociation of single supramolecular capsules were observed. In dynamic single-molecule force …

Untersuchungen in lebenden Zellen mit Hilfe neuer Methoden der Einzelmolekülfluoreszenzspektroskopie
… single molecule fluorescence spectroscopy, Abk.: SMFS), zu denen Methoden, wie Totalreflexions-Fluoreszenz Mikroskopie (engl.: total internal reflection fluorescence microscopy, Abk.: TRIFM) und die konfokale Einzelmolekül¬fluoreszenzmikroskopie gehören. Die Stärke der …

Single-Molecule Measurements of Complex Molecular Interactions in Membrane Proteins using Atomic Force Microscopy
Single-molecule force spectroscopy (SMFS) with atomic force microscope (AFM) has advanced our knowledge of the mechanical aspects of biological processes, and helped us take big strides in the hitherto unexplored areas of protein (un)folding. One such virgin land is that of membrane proteins, where …

Integrated silicon photonic two-dimensional grating couplers
… transmission links, based on single-mode fibers (SMFs). On the one hand, there is a large mode-field mismatch between the tiny on-chip Si waveguide with an area of about 0.1 µm² and the external SMF with a core diameter of around 10 µm. In addition, there is a severe discrepancy between the …

On the Seismic Performance of Skewed Special Moment Frame Reduced Beam Section Connections
<p>Special Moment Frames (SMFs) are frequently used in high seismic areas for architecturally constrained designs, as they provide lateral system stiffness without the use of braces which often obstruct views and architectural features. Reduced beam section (RBS) connections are popular SMF …

Mechanochemical Reaction Development for Addition, Elimination, and Isomerization
… that lack the methoxy substituent. The SMFS and sonication results suggest that MeO-gDFC is a more efficient mechanophore source of HF than its 2-methoxy-gem-dichlorocyclopropane analog is of HCl, in contrast to expectations based on trends in force-free reactivity. We apply the …

Quantifying forearc deformation patterns using coastal geomorphic markers
… 3.7 m/ka millennial slip rate. However, if the SMFS slips only every ~1000 years, representing a few megathrust earthquakes, then a slip of ~3.5 m per event would be required to account for the long- term rate. Such event would be equivalent to a magnitude ~6.7 earthquake capable to generate a …

Investigation of biological macromolecules using atomic force microscope-based techniques
The atomic force microscope (AFM) provides a powerful instrument for investigating and manipulating biological samples down to the subnanometer scale. In contrast to other microscopy methods, AFM does not require labeling, staining, nor fixation of samples and allows the specimen to be fully …
