Significant questions remain in respect to cellulose's structure and polymorphs, particularly the cellulose surface layers and the bulk crystalline core as well as the conformational differences. Total Internal Reflection Sum Frequency Generation Vibrational Spectroscopy (TIR-SFG-VS) combined with conventional SFG-VS (non-TIR) enables selectively characterizing the molecular structures of surfa...

In order to rapidly produce, using high level synthesis, quality silicon implementations of Signal Flow Graphs (SFGs) for large size, real-world signal/image processing problems, the Hardware Description Language (HDL) representations of SFG nodes should possess certain desirable characteristics. We have embedded in DG2VHDL, a design tool developed by the authors which translates automatically ...

In this paper, a non-cooperative two person zero-sum static game(with in a discrete interval of time) is formulated and analyzed for the interaction between the SYN flood attacker and the web server administrator. The SYN flood game (SFG) payoffs are calculated based on Erlang loss queuing model. The solution of the SFG leads to mixed strategy and analyzed for different scenarios the numerical ...

The lineshape and intensity of SFG signals of CO adsorbed on supported Pd nanoparticles and Pd(111) are analyzed. For CO/Pd(111) nearly symmetric lorentzian lineshapes were observed. Applying two different visible wavelengths for excitation, asymmetric lineshapes observed for the CO/Pd/Al2O3/NiAl(110) system are explained by a lower resonant and a higher non-resonant SFG signal and a change in ...

A new method based on Shannon-Happ formula to calculate transfer function from Signal Flow Graph (SFG) is presented. The algorithm provides an explicit approach to get the transfer function in a format with both numerical and symbolic expressions. The adoption of the symbolic variable in SFG, which could represent the nonlinear item or the independent sub-system, is achieved by variable separat...

Sum frequency generation vibrational spectroscopy (SFG) and quartz crystal microbalance with dissipation monitoring (QCM-D) are employed to study the interfacial structure and adsorbed amount of the amino acids L-lysine and L-proline and their corresponding homopeptides, poly-L-lysine and poly-L-proline, at two liquid-solid interfaces. SFG and QCM-D experiments of these molecules are carried ou...

Visual exploration of flow fields is important for studying dynamic systems. We introduce semantic flow graph (SFG), a novel graph representation and interaction framework that enables users to explore the relationships among key objects (i.e., field lines, features, and spatiotemporal regions) of both steady and unsteady flow fields. The objects and their relationships are organized as a heter...

Analysis of 15 spotted fever group (SFG) and 2 typhus group strains of rickettsiae with a panel of monoclonal antibodies revealed a number of shared and unique epitopes of the 120- and 155-kilodalton surface proteins. All of the SFG strains but neither of the typhus group strains reacted with antibody to the lipopolysaccharidelike antigen of Rickettsia rickettsii; possibly the lipopolysaccharid...

Precise rules for locating the anatomical boundaries of the dorsolateral prefrontal cortex (DLPFC) or its subdivisions, i.e., superior, inferior and middle frontal gyri (SFG, IFG and MFG) on magnetic resonance images (MRI), have not been defined. The present study describes the inter-rater reliability of manual segmentation of the SFG, IFG and MFG using guidelines based on sulcal-gyral anatomic...

Time and frequency domain sum-frequency generation (SFG) were combined to study the dynamics and structure of self-assembled monolayers (SAMs) on a fused silica surface. SFG-free induction decay (SFG-FID) of octadecylsilane SAM in the CH stretching region shows a relatively long time scale oscillation that reveals that six vibrational modes are involved in the response of the system. Five of th...
