This modeling is performed on an experimental data set of complexes, where the metal ions of these complexes include transition ion metals and lanthanide ion metals. We use these models to develop a series of new thiosemicarbazone and their complexes; simultaneously, the complexes are worked out the stability constants from the novel models.

The purpose of this paper is to study the characteristics of competitiveness in firms’ sectors of the Greek manufacturing industry, based on firm level accounting and qualitative data attempting to identify key issues regarding Greek SMEs. An unbalanced data set of 407 Greek manufacturing SMEs is implemented, covering the period of 2003-2011 with the use of a multivariate regression model (EGLS) with explanatory variables characterizing firms’ operational activity.

Copaxone is an efficacious and safe therapy that has demonstrated clinical benefit for over two decades in patients with relapsing forms of multiple sclerosis (MS). On an individual level, patients show variability in their response to Copaxone, with some achieving significantly higher response levels.

The purpose of this study is to analyze the effects of supply chain innovation and business strategy formulation to business performance. This study analyzes supply chain innovation and how SME compile their business strategy in industrial clusters. Design of this study is quantitative. We develop a multivariate estimation model to analyze the relationship among constructs. We conduct surveys in 3 different SME clusters, they are shoes and sandals cluster in Mojokerto East Java, furniture cluster in Sukoharjo, Central Java and mushroom cluster in Yogyakarta.

Genome-wide association studies (GWAS) of Alzheimer’s disease (AD) have identified several risk loci, but many remain unknown. Cerebrospinal fluid (CSF) biomarkers may aid in gene discovery and we previously demonstrated that six CSF biomarkers (β-amyloid, total/phosphorylated tau, NfL, YKL-40, and neurogranin) cluster into fve principal components (PC), each representing statistically independent biological processes.

While PD-L1 expression and neutrophil-to-lymphocyte ratio (NLR) are prognostic biomarkers for lung cancer, few studies have considered their interaction. We hypothesized that the product of PD-L1 expression (tumor proportion score) and the NLR (PD-L1×NLR) might be a postoperative prognostic marker refecting the immune microenvironment of lung cancer.

To develop a clinical model for predicting high axillary nodal burden in patients with early breast cancer by integrating ultrasound (US) and clinicopathological features. Our model based on US variables and clinicopathological characteristics demonstrates that can help select patients with≥3 LNs, which can in turn be helpful to predict high axillary nodal burden in early breast cancer patients and prevent unnecessary axillary lymph node dissection.
