BACKGROUND Low back pain (LBP) is one of the most frequent musculoskeletal conditions in industrialized countries and its economic impact is important. Spinal manipulation therapy (SMT) is believed to be a valid approach in the treatment of both acute and chronic LBP. It has also been shown that SMT can modulate the electromyographic (EMG) activity of the paraspinal muscle. The purpose of this ...

Inheritance hierarchies play a central role in object oriented languages as in knowledge representation systems. These hierarchies are acyclic directed graphs representing the underline structure of objects. This paper is devoted to the study of eecient algorithms to decompose recursively an inheritance hierarchy into independent subgraphs which are inheritance hierarchies themselves. This proc...

OBJECTIVE To determine the efficacy and safety of intradural-epidural analgesia in comparison with continuous epidural analgesia during labor and childbirth. PATIENTS AND METHOD Forty-two women whose labor began spontaneously were enrolled and distributed randomly in two groups. The intradural-epidural analgesia group (IEA, n = 21) received 25 microgram of intradural fentanyl with 2.5 mg of i...

PLCtechniques contain software packages for advanced control based on mathematical methods. S7-1200 tools are designed to increase the Process Capacity, yield, and quality of products. Most ofthe present time digital industry r...

Let E be a strong pseudorandom permutation (or SPRP) secure enciphering scheme (i.e., a length-preserving encryption scheme) which can only encrypt messages of size multiple of n, the block size of the underlying block cipher. There are several such constructions, e.g., CBC mode or cipher block chaining mode. In this paper we present how a secure enciphering scheme E can be obtained which can e...

The alternating direction method of multipliers (ADMM) is a benchmark for solving a linearly constrained convex minimization model with a two-block separable objective function; and it has been shown that its direct extension to a multiple-block case where the objective function is the sum of more than two functions is not necessarily convergent. For the multipleblock case, a natural idea is to...
