Piezoelectric polymer fibers offer a fundamental element in intelligent fabrics with their shape adaptability and energy-conversion capability for wearable activity health monitoring applications. Nonetheless, realizing high-performance smart faces technical challenge due to the relatively low piezoelectric performance. Here, we demonstrate yarns simultaneously equipped structural robustness me...

Cross sectional estimation of convergence regressions is known to be hazardous if there is convergence towards heterogeneous steady state values. In this paper, Monte Carlo methods are used to investigate the implications of this parameter heterogeneity problem. The cross sectional and pooled OLS estimators are compared with a panel estimator which is unaffected by heterogeneity. If there is he...

Abstract The analytic hierarchy process (AHP) is a cornerstone of multi‐criteria decision analysis, enabling well‐informed choices across diverse contexts. This paper introduces an original benchmark‐based framework designed to enhance the precision consistency classification for pairwise comparison matrices (PCMs) within AHP methodology. innovative approach quantifies discrepancy between given...

The progress of deep learning architectures, machine models and pathology slide digitization is an encouraging step toward meeting the growing demand for more precise classification prediction diagnosis breast tumours. BreakHis dataset with four magnification factors (40X, 100X, 200X 400X), as well seven architectures used feature extraction (DenseNet 201, Inception ResNet V2, V3, 50, MobileNet...

We consider a number of unit root tests for micro panels where the number of individuals is typically large, but the number of time periods is often very small. As we discuss, the presence of a unit root is closely related to the identification of parameters of interest in this context. Calculations of asymptotic local power and Monte Carlo evidence indicate that two simple t-tests based on ord...

Self-Employment Dynamics, State Dependence and Cross-Mobility Patterns This paper analyzes the mobility between self-employment, wage employment and nonemployment. Using data for men in West Germany, we find strong true state dependence in all three states. Moreover, compared to wage employment, non-employment increases the probability of self-employment significantly, and self-employment goes ...

This paper empirically investigates the impact of macroeconomic uncertainty on the spreads of credit default swaps (CDS). While existing literature acknowledges the importance of the levels of macroeconomic factors in determining CDS spreads, we show that the second moments of these factors—macroeconomic uncertainty—predict CDS spreads even in the presence of traditional macroeconomic factors s...

SCP-1 is a novel tumor antigen that belongs to the growing family of cancer/testis (CT) antigens, and it is a potential target for immunotherapy. In an effort to determine the expression of SCP-1 in epithelial ovarian cancer (EOC), one-step RT-PCR was performed with RNA from epithelial ovarian tumor tissues and with two normal ovarian surface epithelial cell lines. We used immunohistochemistry ...

Ensemble methods have been shown to be an effective tool for solving multi-label classification tasks. In the RAndom k-labELsets (RAKEL) algorithm, each member of the ensemble is associated with a small randomly-selected subset of k labels. Then, a single label classifier is trained according to each combination of elements in the subset. In this paper we adopt a similar approach, however, inst...

abstract production is a process by which a productive activity will require some conditions (before and after the start of the production). one of the most important pre-required factors for start up a production unit is suitable business environment. one of the most important factors that must be provided after the start of production -during the production process and the time to market and ...
