Abstract Preferential attachment is an important mechanism in the structural evolution of complex networks.However, though resources on a network propagate and have an effect beyond a direct relationship, growth by preferential attachment based on indirectly propagated resources has not been systematically investigated.Here, we propose a mathematic
Financial Fraud Detection Using Value-at-Risk With Machine Learning in Skewed Data
The significant losses that banks and other financial organizations suffered due to new bank account (NBA) fraud are alarming as the number of online banking service users increases.The inherent skewness and rarity of NBA fraud instances have been a major challenge to the machine learning (ML) models and happen when non-fraud instances outweigh the
Endothelial cells stimulate growth of normal and cancerous breast epithelial cells in 3D culture
Abstract Background Epithelial-stromal interaction provides regulatory signals that maintain correct histoarchitecture and homeostasis in the normal breast and facilitates tumor progression in breast cancer.However, research on the regulatory role of the endothelial component in the normal and malignant breast gland has largely been neglected.The a
Prolonged Paroxysmal Sympathetic Storming Associated with Spontaneous Subarachnoid Hemorrhage
Paroxysmal sympathetic storming (PSS) is a rare disorder characterized by acute onset of nonstimulated tachycardia, hypertension, tachypnea, hyperthermia, external posturing, and diaphoresis.It is most frequently associated with severe traumatic brain injuries and has been reported in intracranial tumors, hydrocephalous, severe hypoxic brain injury
Extended power-law scaling of air permeabilities measured on a block of tuff
We use three methods to identify power-law scaling of multi-scale log air permeability data collected by Tidwell and Wilson on the faces of a laboratory-scale block of Topopah Spring tuff: method of moments (M), Extended Self-Similarity (ESS) and a generalized version thereof (G-ESS).All three methods focus on <i>q</i>-th-order sample s
