A stress‐balance‐based critical Weber number for droplets and bubbles

open access: yesAIChE Journal, EarlyView.
Abstract Predicting droplet and bubble breakup in turbulent flows is critical for optimizing multiphase flow processes such as emulsification and atomization. Traditional models based on a fixed critical Weber number (Wec$$ {We}_c $$) may not capture interfacial‐stress dominance in low‐viscosity fluids or viscous resistance in high‐viscosity droplets ...

Experimental and numerical study of liquid–liquid systems using the Euler–Lagrange/VOF approach

open access: yesAIChE Journal, EarlyView.
Abstract Achieving stable liquid–liquid dispersions with controlled droplet size remains a challenge due to the complex interplay of dispersed phase viscosity, hydrodynamic conditions and interfacial interactions. This work presents a validated computational framework for droplet breakage and coalescence in liquid–liquid dispersions with variable ...

Sports Activity Recognition Using Textile‐Based Sensor Fusion and Complex‐Valued Residual Convolutional Neural Networks

open access: yesAdvanced Intelligent Systems, EarlyView.
Motion artifacts in electrocardiographic signals, conventionally dismissed as noise, are shown to encode discriminative activity information. A smart t‐shirt fusing textile strain sensors with textile ECG electrodes, processed through a complex‐valued residual network, recognizes 12 sport activities.

The Impact of Paternity Leave on Long-term Father Involvement [PDF]

open access: yes
Using Norwegian registry data we investigate how paternity leave affects fathers’ long-term earnings. In 1993 Norway introduced a paternity quota of the paid parental leave.

Firm turnover under asymmetric information: Tanzania's agro‐dealer sector

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract We study firm turnover (i.e., entry and exit) and its consumer implications in a market characterized by asymmetric information. Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.

DOES MOTHER KNOW BEST?: A COMPARISON OF BIOLOGICAL AND SOCIAL FATHERS AFTER A NONMARITAL BIRTH [PDF]

open access: yes
High rates of nonmarital childbearing combined with high rates of instability and repartnering in nonmarital relationships portend that a large proportion of children born to unmarried mothers can expect to spend time with a ‘social father.’ This paper ...
