We have used dielectric spectroscopy and temperature modulated differential scanning calorimetry (TMDSC) to investigate the structural relaxation processes and phase transitions of water and lipids in multilamellar, planar phospholipids. At low hydration levels we observe the main structural relaxation related to the glass transition of the phospholipids. With increasing water content a more pr...

The electronic and structural properties of a material are strongly determined by its symmetry. Changing the symmetry via a photoinduced phase transition offers new ways to manipulate material properties on ultrafast timescales. However, to identify when and how fast these phase transitions occur, methods that can probe the symmetry change in the time domain are required. Here we show that a ti...

Hollow micro/nano structures form an important family of functional materials. We have used the thermal oxidation process combined with the passage of electric current during a structural phase transition to disclose a colossal mass diffusion transfer of Ti ions. This combination points to a new route for fabrication of hollow materials. A structural phase transition at high temperature prepare...

Structural congruences have been used to define the semantics and to capture inherent properties of language constructs. They have been used as an addendum to transition system specifications in Plotkin’s style of Structural Operational Semantics (SOS). However, there has been little theoretical work on establishing a formal link between these two semantic specification frameworks. In this pape...

Recent studies have shown that firms credit rating transition process is not stationary and may have structural breaks. To study the predictability of structural breaks, we develop a predictive model for latent structural breaks in firms rating transition dynamics, using historical records of (highdimensional) economic and market fundamentals. As a large number of economic and market variables ...

The thermally elicited structural and conformational transitions of the polynucleotide analog, poly(-)-2-[2-(thymin-l-yl)propanamido]propenoic acid, P(-YTDHA, have been studied using differential scanning calorimetry (DSC), differential thermal analysis (DTA), and thermogravmetric analysis (TGA). The differential scanning calorimetry curves obtained on solid P(-)TDHA samples exhibited five dist...

To clarify mechanisms of folding and unfolding of proteins, many studies of thermal denaturation of proteins have been carried out at low protein concentrations because in many cases thermal denaturation accompanies a great tendency of aggregation. As small-angle x-ray scattering (SAXS) measurements are liable to use low-concentration solutions of proteins to avoid aggregation, SAXS has been re...
