The Carnegie classification system has served as a framework for research on colleges and universities for more than 30 years. Today, the system’s developers are exploring criteria that more effectively differentiate among institutions. One approach being considered is classifying institutions based on students’ educational experiences. This study explored whether it is possible to create a typ...

We discuss the problem of global invertibility of nonlinear maps defined on the finite dimensional Euclidean space via differential tests. We provide a generalization of the Fujisawa-Kuh global inversion theorem and introduce a generalized ratio condition which detects when the pre-image of a certain class of linear manifolds is non-empty and connected. In particular, we provide conditions that...

Glioblastoma, the most dangerous and aggressive type of CNS tumor, appears resistant to many chemotherapy drugs. In patient-derived glioma cell lines NULU ZAR, which exhibit drug-resistant phenotypes, we investigated effect combined AE (Aloe-emodin) TMZ (temozolomide) found a significant additive inhibitory on growth promising cytotoxic both compared treatment with single agents. We also examin...
