Recent methodological developments building on partial least squares (PLS) techniques and related ideas have significantly contributed to bridging the gap between factor-based and composite-based structural equation modeling (SEM) methods. PLS-SEM is extensively used in the field of e-collaboration, as well as in many other fields where multivariate statistical analyses are employed. We compare...

New developments in scanning electron microscopy (SEM) have resulted in a wealth of new applications for cell and molecular biology as well as related biological disciplines. New instrument developments coupled with new sample preparation techniques have been key factors in the increasing popularity of this versatile research tool. The desire to view biological material in native states at high...

Background: Effective debris and smear layer removal affects post-cementation bond strength. Aim: The aim was to compare the effectiveness of using standard irrigation activated with heated EDTA. Moreover, an irrigant activation technique chosen in current research, employing ultrasonic EDTA solution after being directly inside post space preparation. Materials Methods: 30 single-rooted human m...

All too frequently, a software cost estimate is required in the early stages of the life-cycle when requirements and design specifications are immature. To produce a cost estimate under these conditions requires extensive use of expert judgment and addressing significant estimation uncertainty. Research has shown that expert judgment under the right conditions can yield relatively "accurate" es...

Abstract. Among many structural health monitoring (SHM) methods, guided wave (GW) based method has been found as an effective and efficient way to detect incipient damages. In comparison with other widely used SHM methods, it can propagate in a relatively long range and be sensitive to small damages. Proper use of this technique requires good knowledge of the effects of damage on the wave chara...
