Extension of lower probabilities and coherence of belief measures
Coherence is an important concept which is introduced and discussed in a new mathematics branch, Imprecise Probability Theory. By using the Choquet integral, belief measures can be extended to be coherent lowe...

Reliability Analysis of Load Path-Dependent Structures
The state of a structure can be described in terms of the complete set of state variables at any given time in its lifetime [1,2,4,5,7]. If the state of the structure is independent of the loading history, the...

Rapid Confocal Measurements of Ca2+ Sparks in Rat Ventricular Myocytes
The initiation of contraction in mammalian myocardial cells begins with the entry of Ca2+ through sarcolemmal Ca2+ channels (DHP-receptors) and triggering of Ca2+ release from the sarcoplasmic reticulum (SR) via ...

Chapter
Synthesis of β and γ-Substituted Prolines for Conformation-Activity Relationship Studies of the α-MSH Analogue MT-II
Substituted prolines have limited rotational freedom about χ1 and χ2, and therefore can be used as unique probes for conformation-activity studies by incorporating them into biologically important peptides [1]...
