A compartmental model for Hepatitis B virus incorporating vaccination, medication, liver transplantation and environmental persistence

open access: yesMathematical and Computer Modelling of Dynamical Systems
Hepatitis B virus (HBV) remains a major public health concern because of its chronic progression and severe liver complications. We propose a compartmental model describing HBV transmission that incorporates vaccination, antiviral treatment, liver ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

A Mathematical Model for Integrating Product of Two Functions [PDF]

open access: yes, 2012
Integration by parts is a well-known method of integrating product of two functions. If the integrand involves a polynomial  of degree n and another function  that can be integrated at least (n+1) times, then the solution to     is guaranteed after n ...
