General principles of protein structure, stability, and folding kinetics have recently been explored in computer simulations of simple exact lattice models. These models represent protein chains at a rudimentary level, but they involve few parameters, approximations, or implicit biases, and they allow complete explorations of conformational and sequence(More)
What role does side-chain packing play in protein stability and structure? To address this question, we compare a lattice model with side chains (SCM) to a linear lattice model without side chains (LCM). Self-avoiding configurations are enumerated in 2 and 3 dimensions exhaustively for short chains and by Monte Carlo sampling for chains up to 50 main-chain(More)
Several systemic diseases share clinical, pathologic and radiologic characteristics. This article emphasizes similarities and differences in the clinical and chest radiographic manifestations of six diseases with both pulmonary and renal abnormalities-Goodpasture's syndrome, Wegener's granulomatosis, lymphomatoid granulomatosis, Churg-Strauss syndrome,(More)
What is the basis for the two-state cooperativity of protein folding? Since the 1950s, three main models have been put forward. 1. In 'helix-coil' theory, cooperativity is due to local interactions among near neighbours in the sequence. Helix-coil cooperativity is probably not the principal basis for the folding of globular proteins because it is not(More)
This paper evaluates the relation between Alcohol Withdrawal Syndrome tremors in the left and right hands of patients. By analyzing 122 recordings from 61 patients in emergency departments, we found a weak relationship between the left and right hand tremor frequencies (correlation coefficient of 0.63). We found a much stronger relationship between the(More)
In this paper, we propose a signal processing method of assessing the severity tremors caused by alcohol withdrawal (AW) syndrome. We have developed an iOS application to calculate the Clinical Institute Withdrawal Assessment (CIWA) score which captures iPod movements using the built-in accelerometer in order to reliably estimate the tremor severity(More)
In this paper, we have introduced a novel method to extract involuntary tremor movement activity in patients with Alcohol Withdrawal Syndrome (AWS). Using the Empirical Mode Decomposition (EMD), we show that the variations of energy of the tremor and voluntary activity can be distinguished in different Intrinsic Mode Functions (IMF) of the recorded tremor(More)
