We present a detailed look at using Mach-Zehnder modulator generated distortion for identifying the magnitude and relative sign of photodiode generated second order intermodulation distortion (IMD2). Previous discussions introduced the concept for characterizing a test device. Analysis is expanded to IMD2 as a function of voltage, photocurrent and frequency.

Background: The World Health Organization (WHO) recommends an interval of at least 24 months from the date of a live birth to the conception of the next pregnancy in order to reduce the risk of adverse maternal, perinatal, and infant outcomes. There is limited data about the implementation of this recommendation and its contributing factors in low-land ecologies in Oromia, which is the biggest regional state in Ethiopia.
Objective: To assess the inter-pregnancy interval and determine associated factors among parous women in selected low-land districts of Arsi and East Shoa Zone.

Objective: Photopolymerized resin composites are widely used as dental filling materials. However, the shrinkage stress generated during photopolymerization can lead to marginal microcracks and eventual restoration failure. Accurate assessment of the stress evolution in dental restorations, particularly in complex cavity geometries, is critical for improving the performance and longevity of the dental filling materials.

Localized high-concentration electrolytes (LHCEs) offer a new methodology to improve the functionality of conventional electrolytes. Understanding the impact of antisolvents on bulk electrolytes is critical to the construction of sophisticated LHCEs. However, the mechanism of how antisolvent modulates the electrochemical reactivity of the solvation structure in LHCEs remains unclear.
